Questions - Essay Example US officials, on the other hand, viewed nuclear energy as having potential non-military benefits, thus giving rise to atomic diplomacy, in which the US sought to prove to the USSR that it was capable and willing to execute a nuclear attack (Ross 33). Atomic diplomacy was used in the Korean War, the first confrontation between the two super-powers, during which the US deployed B-29 bombers as a signal of its resolve, although by 1953, this idea was rejected as a means of coercion to further a cease-fire agreement in the conflict (Arnold & Wiener 21). When the USSR acquired capabilities to deliver nuclear war-heads on Western European and US territories in the late 50s, atomic diplomacy gave way to mutual deterrence, in which the two super-powers refrained from attacking each other due to the certainty of mutually assured destruction. During this period in which the USSR, the US, and its allies were separated by the ‘Iron Curtain’, the West’s general policy was to contain Communist states by keeping them within their present borders and hoping for internal failure and division that would end their threat (Arnold & Wiener 22). Although Dr. Martin Luther King Jr. (MLK) was not the founder of the Civil Rights Movement, he can be considered its formative figure and its de facto leader due to his sacrifices and the influence he had on some of its most seminal milestones (Ward & Badger 18). MLK was one of the first African American leaders to advocate for a social movement against racial segregation that used non-violent means, which was a hallmark of the Civil Rights Movement. He provided leadership for the Civil Rights Movement, which sought to end racial discrimination and segregation against blacks, while also securing federal protection and legal recognition for them as enumerated in federal and constitutional law. He was a major contributor to the Second Reconstruction, which was a

Prevention of Enzymatic Browning in Fruits and Vegetables

Prevention of Enzymatic Browning in Fruits and Vegetables Polyphenol oxidase (PPO) is known to be a key enzyme in enzymatic browning of fruit, vegetables, beverage and seafood in the food industry. The browning of food causes a great quality loss and economic loss of food products. Inhibition of browning by physical treatments has well been developed and there are a wide range of chemicals can also inhibit enzymatic browning. This article overviews the various chemical inhibitors against enzymatic browning in food. Enzymatic browning is one of the major causes in quality loss of vegetables and fruit, beverage and seafood. It is roughly accounted for over 50 percent losses in fruit [1]. It is very important to control enzymatic browning so as to minimize losses and maintain the economic values of the food products. In animal tissues, melanosis is the process results in the formation of dark pigments. The products of melanosis sometimes cause similar visual perception as spoilage and this would make customers not select these products although they are not harmful and do not influence taste of the food. Browning causes many deleterious changes in the organoleptic and nutritional properties of food products that decrease their market values. However, enzymatic browning is beneficial for some of the food products such as tea, coffee, and cocoa. The consumption of fruits and vegetables has been increased due to the nutritional recommendations for health maintain. As a result, the market values of mi nimally processed fruits and vegetables production increases and this will trigger and encourage research in enzymatic browning. Enzymatic browning definition Cell disruption caused by mechanical injury or temperature changes may lead to physiological disorders or even cell death. This loss of cell integrity results in the decompartmentation of phenolic substrates and enzymes [2]. Polyphenol oxidase (PPO) is a critical enzyme catalyzing the oxidation of endogenous phenolic compounds to form grey or brown colors in the enzymatic browning process. PPO is a term which includes a large number of related copper-containing enzymes, including catechol oxidase, tyrosinase and laccase. In the presence of oxygen, PPO oxidizes mono- and di-phenols to o-quinones. Once the products are formed, they polymerize to form high molecular weight compounds or brown pigments as they are highly reactive. The brownish color could be enhanced when they react with amino acids and proteins [2]. Importance of browning inhibition It is essential to control enzymatic browning in order to reduce the economic loss during fruit and vegetables processing. It is essential to control enzymatic browning for the better development in the food industry. The most common way used for the inhibition of browning is the addition of sulfating agents to inhibit PPO. However, sulfite is a toxic molecule and can react with a variety of humoral and cellular components and can cause toxicity [3]. Due to the adverse health effects caused by sulfites, alternative compounds are investigated for anti-browning properties. The ideal compound would be the one which is effective, does not cause any quality loss (eg. taste, flavor, nutritional values) and toxicity, as well as low cost. Until now, many approaches are available to inhibit enzymatic browning, which include the use of ascorbic acid, sodium chloride, kojic acid, 4-hexylresorcinol etc. Enzyme inhibitors, reducing agents, acidulant agents, chelating agents and complexing agents are the common chemical treatments of antibrowning [4]. In order to have a better control of enzymatic browning, it is important to understand its mechanism of actions, the property of the enzyme, substrates, products and their interactions. Minimizing the negative sides of enzymatic browning can extend the shelf life and increase the market value of the food products. Physical inhibition Physical treatments are one of the common approaches in the control of enzymatic browning in the food industries. Hot-air drying, freeze-drying, canning and bottling are examples of some preventive methods. Browning is enhanced by wounding of plant tissue as it stimulates phenolic biosynthesis, hence minimizing the mechanical damage of fruit and vegetables reduce the degree of browning. Reducing the temperature can slow down the rate of enzymatic browning as enzymes are generally inactive at low temperature. However, color change still occurs at 0oc, hence it is important to allow the crystallization temperature of water to be reached as rapidly as possible [5]. Color change would be blocked during commercial frozen (-18oC). When the temperature rises again, browning starts and the rate will be greater if the cellular structure of the plant tissues is damaged by freezing, peeling and slicing [5]. Heating or blanching is the simplest method to inhibit browning by denaturing the enzyme PPO. Heating temperature and time are crucial to maintain the quality of the food products as heating will affects the texture, taste, flavor and nutritional value of the food. PPO is completely destroyed at 80oC [6], but sufficient time is required for the interior part of the fruit or vegetables to reach such temperature. Blanching the green beans for 3.5 minutes at 82 oC and above, inactivated catalase, lipoxygenase, and polyphenol oxidase activities completely[6]. Protection of the fruit and vegetables from oxygen can prevent enzymatic browning when the plant organs cannot be branched. A variety of methods are used in food industries, including airtight package, partial vacuum and oxygen-poor atmosphere. Chemical inhibition Chemicais are the most commonly used for the control of enzymatic browning, but their use in processed food products is restricted to compounds that are nontoxic, wholesome and that do not adversely affect the quality[7]. Inhibition of enzymatic browning can be achieved by hindering the enzyme or by binding to its active site which lower the PPO activity. Chelating agents which remove the copper prosthetic group from PPO can inhibit enzymatic browning. Removing the substrates is another way to prevent enzymatic browning. Substances which undergo complexation with the phenolic substrate and enzymatic modification of phenols are possible ways to inhibit enzymatic browning. Besides substrate, inhibition targeted toward the products, o-quinones, can also be an approach to control enzymatic browning. Chemical inhibitors of enzymatic browning in food will be discussed in detail in this essay. Polyphenol oxidase Definition PPOs are first discovered in mushrooms by Schoenbein in 1856. They are copper-containing proteins and belong to the group of oxidoreductases. A copper prosthetic group is required for its activity. In the presence of oxygen, polyphenol oxidase catalyses reaction of monophenols to o-diphenols (monophenol oxidase activity). It also oxidises o-diphenols to o-quinones (dipehnol oxidase activity). The enzyme in plants have both mono-and diphenol oxidase activity and the ratio of monophenol to diphenol oxidase activity is usually 1:10 to 1:40. [8]. PPO is present in a wide variety of plants and the activity varies from one organ to another and varies inside an organ, depending on the types of tissues or cells. The role of PPOs in plants is believed to resist the infection of microorganisms and virus and to extreme climatic conditions. PPOs are also in involved the development of dark pigmentation in animals. The biosynthesis of melanin pigments and other polyphenolic compounds which often provide a protective function [1]. Indeed, there are many studies concerning the prevention of melanin formation on the face by inhibiting tyrosinase activity, so as to develop whitening agents for the cosmetic industry. Nomenclature Nomenclature of PPOs is sometimes confusing due to their similarity in nature. Jaenicke and Decker write Probably there is no common tyrosinase: the enzymes found in animals, plants and fungi are different with respect to their sequences, size, glycosylation and activation [9] PPOs must have a dinuclear copper centre, in which type 3 copper is bound to histidine residue in their active sites, and this structure is highly conserved [10]. PPOs are normally classified into three types for the convenient use of the term: Catechol oxidase Catechol oxidase (1,2-benzenediol: oxygen oxidoreductase, EC1.10.3.1) has both monophenol oxidase and diphenol oxidase activity. It is the most common form of PPOs in plants that when people talked about PPOs in food it normally refers to catechol oxidase. Reports on the molecular weight of plant PPO are very diverse and variable and it is estimated the molecular masses of PPOs ranges from 20 to 180kDa [2]. Most of the studies show PPOs have an optimum activity between pH 4 and 7, but some reports show that pH optima varies with the proportions of isoenzymes as well as phenolic substrates used [2]. The optimum temperature of PPOs ranges from 15 to 40 oC and this also depends on the same factors as pH. Tyrosinase Tyrosinase (EC1.14.18.1, monophenol, L-DOPA: oxygen oxidoreductase) refers to as monophenol monooxygenase and corresponds to the same enzymes as EC1.10.3.1 but which always catalyze the hydroxylation of monophenols. In aminals and fungi, PPOs are refered to tyrosinase as L-tyrosine is the major monophenolic substrate. It is very similar to catechol oxidase and sometimes tyrosinase is referred as PPOs. It catalyze two distinct reactions of melanin synthesis: the hydroxylation of tyrosine and the oxidation of 3,4-dihydroxyphenyphenalanine (L-DOPA) to o-dopaquinone. Tyrosinase has been a great concern in humans in the cosmetic industry as it plays a key role in mammalian melanogenesis, which leads to the formation of dark macromolecular pigments, melanin. Laccases Laccase (p-diphenol oxidase, E.C. 1.10.3.2)(DPO), has the unique ability to oxidase p-diphenols into their corresponding quinones, which allows it to be distinguished from catechol oxidase. The enzyme contains many subunits and there are three types of copper centers in each subunit. They occur mainly in fungi and higher plants while much less frequently in the plant kingdom than PPOs. They are glycoproteins with a carbohydrate content of about 15-41% and they have a molecular weight of about 60 to 80 kDa. Substrate Phenolic compounds are substrates for PPOs. There is a wide variety of phenolic compounds found in plants, but only a small number serves as direct substrates for PPOs. Degree of enzymatic browning varies widely from one plant to another. Not only content of PPOs contributes to the variation, quantitative and qualitative aspects of their phenolic content also affect enzymatic browning in fruit and vegetables. In the studies of enzymatic browning in various fruits such as apples, grapes, and peaches, the effects of phenolic content and polyphenol oxidase on the rate of enzymatic browning have been reported [11-13]. Phenolic compounds contain an aromatic ring with one or more hydroxyl groups, together with other substituents. The differences in species, ripening and environmental conditions of growth and storage influence the phenolic composition of plants. Phenolic compounds are essential in fruit and vegetables as they contribute to flavor, color and taste in fruits. Flavonoids are t he major phenolic compounds occurred in plants. Caffeic acid derivatives and monomeric flavan-3-ols often appear to be the best substrates [2]. In some cases, phenolic compounds which are not direct substrates can also take part actively in enzymatic browning by coupled oxidation reaction. Tyrosine, an amino acid, is a monohydroxy phenol and it is an important substrate for PPOs in animals. Caffeic acid derivatives, such as chlorogenic acid, the major diphenolic compounds in plants, act as substrates for polyphenol oxidases. Chlologenic acid is the main substrates for enzymatic browning in apples. On the other hand, some phenolic compounds may also act as inhibitors for PPOs. Apple polyphenol oxidases can be inhibited by various cinnamic acids acting as substrate analogues [1]. Mechanism of action Monophenol oxidase activity for the hydroxylation reaction is normally slower than the oxidation reaction for the production of quinine, which leads to the initiation of the polymerization reaction. Thus it is the rate determining step in the production of brown pigments from monophenols. One mole of oxygen is required for the reaction as shown in Figure 2. When there are only diphenolic substrates, production of the brown pigments will be faster due to their high catalytic rate in the formation of quinines. The primary products, o-quinones, are reactive and unstable compounds, which can undergo further oxidation to brown melanin pigment (figure 3). O-quinones are strong electrophiles which can suffer nucleophilic attack by water, other polyphenols, amino acids and proteins, leading to Michael-type addition products [14-16]. The final products have more intensive color than the o-quinones. Their color depends on the phenol from which they originate. Chemical inhibitors of PPO Plant Polyphenols Polyphenols are a diverse group of compounds having multiple phenolic functionalities [18]. Plants are a rich source of polyphenols which are almost free of harm effects. There are continued investigations of tyrosinase inhibitors from plant extracts, aiming to search what bioactive chemicals in plants have significant inhibitory effect. Flavonoids are one of the most common and best studied groups of plant polyphenols. Flavonoids can be further divided into six subgroups, which are flavanones, isoflavones, flavonols, flavanols, flavones and anthocyanidins. Some flavonoids such as catechin act as substrates for PPO while some of them, eg. quercetin and kaempferol have inhibitory effect on PPO [19, 20]. Isao Kubo studies the inhibition kinetics of kaempferol extracted from saffron flower and it is found that to be a competitive inhibitor, its inhibitory activity presumably comes from its ability to chelate copper in the enzyme [20]. This copper chelation mechanism may be applicable fo r all of the flavonols as long as their 3-hydroxyl group is free [20]. However, 3-o-glycoside derivatives, eg. kaempferol 3-o-glucoside, quercetin 3-o-glucoside, did not inhibit tyrosinase in high concentration [20]. This shows that the free hydroxyl group at C-3 may play an important role in the inhibition. However, some flavones which lack the 3-hydroxyl group, such as luteolin and luteolin-o-glucoside, still have tyrosinase inhibitory effect [21]. (−)-epicatechin 3-O-gallate(ECG), (−)-gallocatechin 3-O-gallate(GCG), and (−)-epigallocatechin 3-O-gallate(EGCG) in tea, especially green tea, are strong inhibitor of tyrosinase and it is found that GCG may act as a competitive inhibitor for the L-tyrosine binding at the active site of the enzyme [22]. It is believed that the flavon-3-ol skeleton with a galloyl moiety at the 3-position is required to inhibit tyrosinase effectively. When the hydrophobicity of gallates increases, the coumpounds are more resistant to be o xidized by tyrosinase as the tertiary structure of the enzyme is disrupted [23]. Structure-Activity Investigations of stilbenes and related 4-substituted resorcinols, obtained from Artocarpus incisus and other plants suggested that the 4-substituted resorcinol skeleton have potent tyrosinase inhibitory ability [24]. Oxyresveratrol, a stilbene isolated from Morus alba, exhibited 32 times inhibitory effect of kojic acid on tyrosinase and the inhibitors act non-competitively on the enzyme [25]. In the structure analysis of extracts from licorice root, glabridin exerts the strongest inhibitory effect on tyrosinase and the inhibitory effect was more effective against monophenol oxidase activity, the rate-determining step, than diphenol oxidase activity [26]. However, glabridins analog, glabrene, was 100-fold less active than glabridine while glyasperin C, isolated from the same part of the plant, was two times more active than glabridin [26, 27]. 6-hydroxydaidzein (6,7,4-trihydroxyisoflavone), one kind of hydroxyisoflavones isolated from soybean koji fermented with As pergillus oryzae, had 6-fold more than kojic acid acting competitively on the tyrosine binding site of the enzyme [28]. It is found that an isoflavone with hydroxyl groups at both the C6 and C7 positions in the A ring would increase both inhibitory effect and affinity to the enzyme more than 10 times [28]. Chalcones, with two aromatic rings in trans configuration, have strong inhibitory effects on tyrosinase. Licochalcone A isolated from the roots of glycyrrhiza species competitively inhibit tyrosinase and the effect was 5.4 times more active than kojic acid [29]. Kuraridin, isolated from Sophora flavescens, was 34 times of the activity of kojic acid in inhibiting monophenolase activity of mushroom tyrosinase [30]. It is believed that the 2,4-dihydroxyl groups in the aromatic ring of chalcone structure was the important substituted group to exert strong tyrosinase inhibitory activity as some simple 4-alkylresorcinols were found to exhibit the strong inhibitory effect [24, 31]. Chelating agents Chelating agents are chemicals that bind to metal ions and remove them from their sphere of action. EDTA (ethylenediaminetetraacetic acid) is a chemical preservative permitted for food industry use. It is a chelator and it is believed that EDTA inhibits PPO activity by either binding to the active copper site of PPO or reduces the availability of copper for the enzyme [7]. the United States Food and Drug Administration approved the use of Calcium disodium EDTA and disodium EDTA to be used as a food additive [32]. EDTA is usually used with other chemicals such as reducing agents (ascorbic acid) and acidulants (citric acid) to prevent enzymatic browning in food. Polyphosphates are another common chelating agent for anti-browning of fresh-peeled fruits and vegetables, but it has low solubility in cold water [7]. Sporix, containing citric acid, ascorbic acid, sodium acid pyrophosphate and calcium chloride, is a powerful chelator and also an acidulant. Browning prevention in apple juice a nd cut surfaces was obtained by Sporix [33]. However, it is not approved in U.S. for food use. Kojic acid (C6H6O4; 5-hydroxy-2-(hydroxymethyl)-4-pyrone), always being use as a standard to compare and study the tyrosinase inhibitory activity of various chemicals in research, is produced by several species of fungi, especially Aspergillus oryzae. Kojic acid possesses both antibacterial and antifungal activities. It is a good chelator and antioxidant that can prevent browning in both plants and seafood. It is commonly found as a food additive and in cosmetic products due to its tyrosinase inhibitory effect. In the phenolic acids tested (caffeic, chlorogenic, cinnamic, coumalic, ferulic, gallic, kojic) for inhibition on PPO, Son et al. reported that kojic acid showed the highest inhibitory activity on apple slice browning [34]. Kojic acid may inhibit the enzyme acting as a reducing agent. If high dose of kojic acid is given to rodents, the level of tyrosine stimulating hormone increases [35]. However, there is inadequate evidence showing that kojic acid would cause cancer in human . Consumption of kojic acid at levels normally found in food does not present a concern for safety [36]. Reducing agent Reducing agents can act as antibrowning agents by reducing the o-quinones back to o-quinones. Ascorbic acid is a good reducing agent and antioxidant which removes oxygen in polyphenol oxidase reactions. As the reaction resulting in the formation of o-quinones is reversible, in the presence of excess reducing agent, o-quinones are reduced to their original o-diphenols. Ascorbic acid is the most widely used antibrowning agent in food due to its reducing property as well as low pH. Since reducing agents act on o-quinones to prevent browning, the effectiveness of ascorbic acids would be decreased if their use is delayed until after the enzymatic reaction has started. In practice, about 0.1-0.3% of ascorbic acid can have protective effect against enzymatic browning. However, one of the drawbacks of ascorbic acid is that it can be oxidized to dehydroascorbic acid irreversibly during the reaction. As a result, it disappears rapidly and browning would occur again upon its depletion (figure 4 ). To overcome its rapid depletion, some derivatives, such as ascorbic acid-2-phosphate (AAP), or ascorbic acid-triphosphate (AATP), are used as substitutes. They are not reducing agents, but when the action of PPO presents they release ascorbic acids. Therefore they will not be oxidized by oxygen rapidly as AAP and AATP can remain stable in the presence of oxygen. Erythorbic acid (EA) has a similar effect and action as Acorbic acid in the inhibiting enzymatic browning. However, it is destroyed at a faster rate than ascorbic acid. Sulphiting agents including sulphur dioxide (SO2) and sulphite are very popular browning inhibitors used in the food industry. It is one of the most effective chemical inhibitors of browning and it is effective even in low concentration. Also, it is inexpensive and hence many food manufacturers use it to inhibit microorganisms growth and enzymes. Sulphur dioxide has three actions to inhibit browning. The first one is its reducing property to reduce o-quinones to its original o-diphenols. The second mechanism involves the formation of colorless products with o-quinones and the last one is that SO2 denatures PPO, resulting in the loss of functionality of the enzyme. Madero and Finne [37] reported that bisulphite could bind to the sulphydryl group at the active site of the enzyme so as to exert competitively inhibit the enzyme. Ferrer et al. [38] proposed that bisulphate inhibited PPO irreversibly by forming sulphoquinones when sulphites react with intermediate quinines, causing complet e inactivation of the enzyme. In addition, it also inhibits non-enzymatic browning that reduces pigmentation of the fruit and vegetables. Sometimes sulphur dioxide treatment is applied before deep-frozen, drying or freeze-drying of fruit and vegetables. In deep-frozen products of apples and apricots, fruit slices are soaked for 3-4 minutes in 0.4-0.5% sulphur dioxide solution. Sulphites are regulatory restricted in food products as it may cause potentially adverse effects on health. There are many reports showing that sulfites are genotoxic in vitro but not in vivo [39]. In the report of the safety evaluation of sulphites as food additives by World Health Organization (WHO), it concluded that when a suitable alternative method of preservation exists, its use should be encouraged, particularly in the applications in the food industry that the use of sulfites is extensive which may lead to its high intake as high level of sulfites in the body may cause life-threatening adverse reactions [39]. Thiol containing (sulfhydryl) compounds are compounds that an oxygen atom in the compound has been replaced by a sulphur atom. Many studies showed these compounds such as cysteine, N-acetyl-L-cysteine and reduced glutathione are able to inhibit enzymatic browning in fruits and vegetables [40]. In this group, cysteine is the most effective anti-browning agent. The proposed mechanism was that it reacted with the quinone intermediates to form stable colorless compounds. The cysteine-quinone adducts are also the competitive inhibitors of PPO. Nicolas et al. showed that cysteine directly inhibits PPO by forming stable complexes with copper [40]. However, use of cysteine is not so encouraged in the food industry because concentration of cysteine used to achieve significant inhibitory effect on PPO would have negative effects on taste. It has also been shown that Maillard reaction products (MRPs) are potential inhibitors enzymatic browning. Amadori rearrangement products, key intermediates in the first states of the Maillard reaction, has chelating, reducing and oxygen-scavenging properties and it might inhibit enzymatic browning [41]. The MRPs derived from glucose with sulfhydryl amino components (cysteine or the tripeptide, glutathione) could be considered as potential natural inhibitors and this was supported by Billuad et al.s study [42]. In a further study conducted by Hesham A. et al., the inhibitory effect of the thiol containing compounds was comparable with 4-hexyl resorcinol and being significantly (p < 0.05) higher than ascorbic acid. The MRPs derived from cysteine/glucose model system were more active than their counterpart derived from cysteine/ribose model system [43]. In a study examining various types of MRPs for their tyrosinese inhibitory effect, monosaccharide-glutathione was more active than glutathione [44]. However, MRPs are unstable and they may negatively affect the sensory quality of the food products as there was unpleasant odor formed from t he apple slices treated with MPRs [44]. Acidulants Most enzymes especially oxidative enzymes activity is very pH-dependent. Extreme pH can denature the enzymes that lead to the loss of the catalytic function. The groups in the active site of the enzymes are ionizable. In the environment of high proton concentration, the structure of the active site may be affected and there may be conformational change that decreases the binding of substrate and catalytic activity. A pH below 3 can effectively inhibit PPO activity [45]. In addition, under extreme pH, substrates may be degraded or change its conformation; as a result, the degraded substrates share the molecular features of the substrates that they may act as enzyme inhibitors [46]. Common acidulants use for PPO inhibition are citric acid, organic acids such as malie, tartaric and malonie acids and inorganic acids such as phosphoric and hydrochloric acids. Citric acid is an acidulants which widely used in the food industry as it is cost effective and highly available. 0.5-2% of it has protective effects against enzymatic browning in fruit and vegetables. The use of 100mmol/L citric acid combined with 10mmol/L glutathione was found to give a great control of browning in litchi fruits and it is recommended this combination can be a good way applied to control litchi fruit quality [47]. Since it is difficult to achieve efficient browning inhibition through pH control solely, citric acid is frequently used in combination with other anti-browning agents, such as ascorbic acid to chelate the copper of the enzyme. However, when the pH is lowered to a level the taste of the food products may be affected and it only can be applied in acidic foods. Complexing agents Complexing agents are able to form complexes with PPO substrates or reaction products, so as to reduce the browning effects. Cyclodextrins and cyclic nonreducing oligosaccharides of six or more D-glucose residues are examples of complexing agents. The hydrophobic central core of cyclodextrins can form inclusion complexes with phenol compounds, leading to the depletion of PPO substrates. Due to the limited space in the core of cyclodextrins, larger guest molecules only partially bind to it and form relatively weak complexes. However, chemical modification of cyclodextrines increases the binding and hence increases the inhibitory effect on PPO. In a study using chlorogenic acid as a substrate to compare ÃŽ ±-, ÃŽ ²- and ÃŽ ³-cyclodextrins in the formation of inclusion complexes, ÃŽ ²-cyclodextrins are more effective in inhibiting browning in apple juice [48]. The internal cavity of ÃŽ ²-Cyclodextrins is non-polar that it induced inclusion complex formation with the phenolic substrates of polyphenol oxidases, preventing them oxidizing to quinones and hence stop the subsequent polymerization to brown pigments. However, complex formation by cyclodextrins is not specific and it may remove the desirable color and flavor compounds of the food product. Cyclodextrins are insoluble in water, so it is better to be used in volatile or insoluble food ingredients in the food industry. The use of cyclodextrins in fruit and vegetable juice are patented, but it have not been approved to use in food by the FDA [49]. Chitosan, a naturally abundant polymer of ÃŽ ²-(1-4)-linked -D-glucosamine, is obtained from the chitin of shellfish. It is widely used in agricultural and horticultural as natural biocontrol and elicitor, water filtration and biomedical. Chitosan is a kind of dietary fibre that have an effect in reducing the absorption of bile salts in the small intestine, hence lowering the blood cholesterol level. It also helps to stop bleeding and has anti-bacterial effects. It is safe and non-toxic, and may even gain health benefits to the body. It has been reported enzymatic browning was inhibited by adding 200 ppm chitosan to Mcintosh apple juice [50]. When 2% of chitosan was treated with shrimp during storage, the incidence of melanosis was reduced [51]. Another study showed that chitosan coating can inhibit enzymatic browning in longan fruits and it can improve shelf life and quality of the fruit [52]. The effect might be due the formation of protective barrier on the surface of the fruit, p reventing the supply of oxygen to PPO. Therefore it is applicable that chitosan can be used in the combination with other agents to control browning and improve quality in fruit and vegetables during post-harvesting and storage. Enzyme inhibitors 4-hexylresorcinol is the one of the most potential PPO inhibitors apply to fresh-cut products. It has obtained the GRAS status for use in the prevention of shrimp melanosis and it proved to be more effective than sulphites in the inhibition of melanosis [7]. Due to its specific mode in the inhibition of enzymatic browning and effectiveness at low concentration, it may be a potential substitute to sulphites. The combination of it with ascorbic acid improved browning control in apple slices [53]. In a study investigating the combination effect of cysteine, kojic acid and 4-hexylresorcinol on the inhibition of enzymatic browning in Amasya apple juice, the interaction of kojic acid and 4-hexylresorcinol was found to have a positive effect on the inhibition of enzymatic browning [54]. Everfresh, a patented product containing 4-hexylresorcinol as the active ingredients and sodium chloride, showed better stability to blackspot formation than sulphites and it is proposed to be use for the in hibition of enzymatic browning in fruit and vegetables [55]. Sodium chloride, or saline water, is widely used in daily life as an anti-browning agent in freshly cut apple. It can also slow the microbial growth in the food products. Its effects on PPO increase when concentration increases. In an experiment examining the effects of salinity on PPO and peroxidase activity, increasing levels of salinity  reduced both oxidases activities immediately after cutting and throughout 7  days of storage [56]. Samples cultivated under high  salinity had also the lowest change in colour and showed the lowest reduction in total phenolic content and antioxidant capacity after 3  days of storage [56]. However, due to its inadequate protective effect at low concentration and unwanted salty flavor at high concentration, its application in the food industry is limited. When it is used with ascorbic acid and acidulants such as citric acid, the inhibitory effect is enhanced and prolonged. However, as the pH is getting higher, the inhibitory effect would dec rease. Its inhibition to PPO might be achieved by interacting with the copper at the active site of the enzyme. Sodium chloride at a concentration of 2-4% is usually used to inhibit browning in the food industry. At 1-2% concentration soaking for less than 1 minute, it can afford temporary protection from surface browning of sliced peeled apples for freezing, or ready-to-use fresh food. Other chemical inhibitors Sodium chlorite is an effective sanitizer inhibiting microbial growth. It can generate chlorine dioxide in acidic environment. Chlorine dioxide is a very powerful oxidizing agent and found to have inhibition in browning reaction. The anti-browning effect of sodium chlorite was gr

My Memories of the State Park Essays -- Personal Experience

When I think about my favorite childhood places to visit, one spot stands out above the rest. My parents took my family to the State Park every year on Columbus Day weekend. Cramped in a station wagon between my three other brothers in the back seat, I remember the car ride to seemingly take triple the amount of time it really took. The time that it took to get to the state park was always increased when my parents would stop for lunch at the half way point, something they did each and every time. I knew we were close when I saw a sign for the Mall. It was a very weathered sign on the side of an even more deteriorating barn that could not have been larger than a classroom. I always laughed to myself about this sign because even though the sign advertised the mall was four miles ahead, the lettering of â€Å"4 miles ahead† was in a text size that you could barely make out as a passenger in a car traveling fifty miles per hour. If you were not paying attention, you would mistake this element torn building as the actual mall and feel a slight pity for the poor town. Though, seeing this sign and feeling the pity was a small price to pay for nearly being at your favorite place on Earth and out of your cramped conveyance. Shortly after the sign, there are road signs for the State Park which lead you to a steep, winding mountain road. Going up this incline in an overstuffed, late model station wagon seemed like it took more time than the two hour car ride it took to get to it. Then, finally, a carved boulder on the right side of the road appeared and proclaimed â€Å"STATE PARK.† This rock always had special meaning to me. It was a massive stone that never shifted from where it settled probably several decades ago. Th... ...ss visitors great experiences and upon arrival to it, it will be your turn to have them. The State Park holds many other places that offer different sorts of ventures, but when you truly respect the land, the tiniest encounters often yield the largest rewards. When you forego visiting the popular tourist destinations and decide to make your own exploits, the possibility of experiencing true freedom is increased. Going to a crowded beachfront by the lake, waiting in lines for bathrooms or to buy worms for fishing has less potential for adventure than simply walking into the woods without so much as a destination. There, in the woods, you will forget for hours that you live in society. Shortly after that absence of thought, you will find yourself doing unexpected and fulfilling activities that will shape your mind and outlook on life for as long as you live.

Ethical dilemmas can international psychologists

The list below though not exhaustive but have been potential dilemmas that international psychologists ace during the execution Of their services in a culturally diverse population: Linguistic competencies- A case in point of such a situation is where immigrants travel in host community and want to use the health opportunities of that community. The medium of exchange for the host community is mainly English and say the immigrant is from a Chinese background.The children of most immigrants tend to adjust quickly in terms of linguistic abilities and therefore are most often interpreters for their parents. A parent of such cultural background seeking mental health services ill rely on the children to interpret for them. The dilemma here is the international psychologist is bound by law not to expose a patient's sensitive document to a third party and also how can the international psychologist ascertained that the patient clearly understood the informed consent interpreted by the child .The steps taken in such a scenario is the need for bilingual staff to facilitate the care of culturally diverse patients (Congress, 2004). Practitioners legal obligation versus workplace policies- Davidson, (201 0, up. 70) reported that workers within the social services will be unfrosted by the dilemma between acting in the ethical best interest of direct service recipients and acting according to the law.For instance, an international psychologist working with an organization in a culture where children or minors work to fend living for their parents will be faced with a dilemma as to whether he is legally obligated to report this illegal activities of the organization or has an obligation to the organization to report. Using individual participants to represent the whole population- In his voice thread, Dry. Larsen (2014) noted that most hypothesis used in testing cross cultural research uses individual participants as a unit of analysis to aggregate an overall score for each cu lture.We are cautioned by the video on cross cultural competence that when working with culturally diverse population, we should delve into the demographics and composition of the group so that at the end all benefits and risk should be proportionately distributed. The ethical issue that arises when we stereotype or generalize the attribute of one culture to encompass the whole is that relationships among the measured rabbles in one culture will not necessarily translate to the same relationship in another culture.

Complete Ramsey Walker’s profit plan Essay

Work assumption: 1. Assume that the sales will increase by 10% for each new title, as indicated the Backlist sales increase. 2. Assume that the total number of new titles remain unchanged; since Ramsey is trying to publish fewer segments and focus more resources on trying to publish fewer segments and focus more resources on differentiation those books in the marketplace, there is no reason for him increase the new titles. 3. Assume that they plan to increase their gross margin by 2% and decrease the expenses of sales by 1%, for each of the six formats, as given for Backlist. 4. Assume that AR as the percentage of sales remains 20%, as indicated by Backlist. 5. Assume that inventory as the percentage of sales decrease by 15%, as indicated by Backlist. 6. Assume that AP as the percentage of sales will stretch to 20%, as the last year percentage for the first five formats is 18%. The 10% increase in sales, 2% increase in GM and 1% decrease in expenses should be critical since it will increase the profit dramatically. And the decrease in inventory is also critical because it will decrease the lower part of the ROA formula. Since the overall goal of the profit plan is to achieve the 10% increase in ROA, so the above assumptions will directly affect the end results. Problem 2: Review the list of financial performance measure presented above. What measures or calculations should Ramsey use to manage the business? How should those measures be calculated? 1. Annual sales growth rate should be used to measure their performance  because this rate helps management to evaluate the quality of their decisions and also helps to make the new strategy for the future development. It is calculated by suing the difference between current year sales and previous years divided by the previous year sales. 2. Profit % is the most critical measurement of a business performance. Without profit or potential to earn profit in the future there is no meaning for a business to continue. It is simply calculated by using profit divided by the sales. 3. Average unit sales help the company to find the right format which is more profitable and more popular, and affect the company’s future strategies. Using the total units sold for one format divided by the total titles in this format. 4. Operating expenses can help them to manage their cost control system, OP can be calculated simply sum up all the expenses in the income statement. 5. POA and ROI are hard to control and too complex to analyze. But these measurements can be calculated by dividing the profit by total asset or total investment respectively, different results can be achieved by suing different assumptions.

6 Things Almost All Writers Get Wrong When Self-Editing

6 Things Almost All Writers Get Wrong When Self-Editing 6 Things Almost All Writers Get Wrong When Self-Editing Lisa Lepki is the Editor of the ProWritingAid blog. A word nerd, she loves the technical elements of writing almost as much as the writing itself. In this post, she reveals a few of the most common editing mistakes that authors make.As an editor, I see writers making the same mistakes over and over again.I’m not talking about narrative or character development here. I’m talking about the technical elements of your text, like sentence construction and word choice. Almost all editors are happy to help you with the meaty parts of your writing, like dialogue and structure, but they get frustrated if they see common rookie mistakes.Believe me, more than one publishing professional has chucked a manuscript in the recycling bin based solely on amateur mistakes like overuse of passive voice or over-reliance on adverbs.Here are six ways that I have seen writers go wrong:1. They try to edit as they writeThe creative part of your brain - that’s in charge of imagining your scenes, conceiving your characters and telling your story -   is very different to the part of your brain you use to edit. Going back and forth between the two of them will make you lose momentum - a key reason why many writers never finish their book.Don’t worry about analyzing every word as you go along. Don’t beat yourself up if you use a clichà © to get an idea across while you are in creative mode. It’s not even a problem if you â€Å"tell† rather than â€Å"show†, as long as you get your story out of your brain and onto the page. All of those issues are easy to fix when you go back and edit.So, for your first draft, just let the words flow. Give yourself the freedom to use the wrong words and have faith that you will be able to go back and find the right ones in due course. "6 Mistakes Authors Make When They Self-Edit" from Lisa Lepki of @ProWritingAid 2. They try to do everything at onceThere is a common problem among writers called â€Å"terrible second-half syndrome,† or TSHS. Okay, I just made that term up, but I promise it’s a thing - because I have done it myself.Somewhere in the depths of my hard drive, there is a manuscript I completed about twelve years ago. This was my first major piece of writing and I was delighted with it! Life got in the way and so I never really did anything with it, but I found it again last year. It had a serious case of TSHS. The first chapter was perfectly crafted, full of powerful imagery and compelling scenes. The second chapter was not quite as well-polished, and then it just went downhill from there. The last chapter didn’t even really make sense! Sound familiar?I see this a lot. Writers start their self-edit full of vigor. They painstakingly assess every word and every construction†¦ and then they begin to lose interest.I get it. Editing can be pretty frustrating ( i.e. boring) if you are more creatively inclined. So, instead of trying to get every element perfect on your first round, I recommend working on one issue at a time.For example, your first round might be Adverb Annihilation:We think the problem began when the company did not produce enough tubes for the experiment.These sentences both say the same thing, but the first one is full of clutter. Here are the problem areas:â€Å"It is our opinion that† is a much more convoluted way of saying, â€Å"We think†.  It is redundant to say that something â€Å"first began†. The word â€Å"began† already means â€Å"first†.You can replace â€Å"due to the fact that† with the much simpler â€Å"when†.â€Å"A sufficient amount of† is a cluttered way of saying â€Å"enough†.Tubes are always hollow, which means that the word â€Å"hollow† is redundant.The passive voice means â€Å"the company† is right at the end of the s entence, delaying its meaning and lessening clarity.We’re not suggesting that you dumb your writing down. We just want your ideas to come across as clearly as possible and if that means cutting back on prepositional phrases, so be it. If readers have to spend time (and brain power) trying to make sense of your language, then they may miss something critical.6. They don’t take time awayOnce you finish your first draft, you need to step away. It’s nearly impossible to evaluative your writing when it’s fresh. You know the idea that you meant to get across, and so you see it in your words... even if it isn’t there!The other benefit of moving into editing mode is that it gives your creative brain a break. Spending a couple weeks copy-editing will allow you to return to your story refreshed. You’ll be able to see those plot holes with fresh eyes.Want to learn more practical self-editing techniques?

Business law - contracts, summary to UCC, and FIRAC on a case Essay

Business law - contracts, summary to UCC, and FIRAC on a case - Essay Example Besides, there is not evidence that can act as a proof. Yes, since Light did not produce the quality services, which they had agreed and contracted prior the start of the exercise. In addition, the liquidated damages were also evident in the contract, which they had instituted besides each swearing to fulfill. No. This is because after Hart had entered into a contract with Brand Smith Roofing, he wrote to them two times before and after contracting with Broadview Roofing & Remodeling Inc. Brand Smith Roofing did not respond and nowhere making efforts to resurface, but continued to make Hart wait indefinitely. Unfortunately, during the case ruling, the magistrate unlawfully favors Brand Smith Roofing. Since, he failed to enforce the compensation of damages incurred by Hart. Yes.

Climate Change - Essay Example Describe three key findings of the AR4 report that are mentioned in the Introduction Section. Key findings include: 1. An increase in global average air and ocean temperatures, widespread melting of snow and ice and rising global sea levels 11 out of last 12 years from 1995-2006 rank among the 12 hottest years on record Global sea level rise of 1.8mm from 1961-2003 Polar ice caps shrinking – Artic sea ice extent shrank 2.7% per decade Changes in precipitation – decline in Mediterranean, Sahel, southern Africa and increase in eastern part of North and South America, North Europe 2. Natural systems are being affecting by regional climate change, particularly temperature increase Glacial runoff increase glacial lake sizes Hydrological effects – increase runoff, earlier spring peak discharge, warming of lakes/rivers, which effects thermal structure and water quality 3. Effects of regional climate change in natural and human environment are emerging, although many are difficult to discern due to adoption and non climatic drivers Agricultural changes – planting crops earlier on in the year Increase in climatic health hazards, e.g. European 2003 heat wave killed 15,000 people in France What is the difference between natural and anthropogenic drivers of climate change? Provide an example of each. Natural changes refer to climatic alterations in the Earth’s atmosphere that aren’t affected by humans. Astronomical Effects Terrestrial Effects Orbital variability of the Earth Global geometry of continent/ocean distribution Solar storms and flares Ocean tide cycles Sunspot cycles Periodic ocean circulation changes, e.g. El Nino These processes control the amount of suns radiation reaching specific latitudinal zones on Earth Volcanic eruptions Anthropogenic drivers have also been highlighted as contributing to climate change and accelerating the warming of the Earth’s atmosphere. Examples include increased CO? (280ppm from pre industrial levels to 379pmm by 2005), burning of fossil fuels, deforestation, CFC’s and aerosols and from agriculture, e.g. cows releasing significant amounts of methane. What is a greenhouse gas (GHG), and how have their levels changed in the atmosphere changed since 1970? A GHG is a gas in the Earth’s atmosphere that contributes to the greenhouse effect through absorbing and emitting radiation causing climate change. They include CO?, methane, nitrous oxide and halocarbons. Changes in the atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balances of climatic systems. There has been a 70% increase in global GHG emissions due to human activities between 1970-2004. CO? annual emissions have increased by 80% from 21 to 38 gigatonnes. CO? also represents 77% of total anthropogenic GHG emissions. Describe the SRES scenarios. What are they, and why do we have more than one of them? SRES refers to the scenarios descr ibed in the IPCC Special Report on Emission Scenarios. The SRES project an increase of baseline global GHG emissions by a range of 9.7 to 36.7 GtCO? – eq (25% to 90%) between 2000-2030. The SRES scenarios are grouped into 4 scenario families (A1, A2, B1, B2). They explore alternative development pathways, covering a wide range of demographic,

Peer Review Coursework Example | Topics and Well Written Essays - 500 words

Peer Review - Coursework Example What is your least favorite and why? My favorite part of this essay was discussing how telephones and cell phones have developed to the point where cell phones are not used for their original purpose, but are more so now used as media devices and the majority of communication is done through text messaging. It was also very inspiring to see how the development of communication devices has affected their lives in that deployment of a loved one can be a very hard thing to deal with due to the lack of communication in a war zone due to security restrictions. My least favorite part was when it was discussed about the different phone companies that exist. This is due to the fact that many cellular companies hold similar policies and price ranges as far as Verizon and Vongage go. 2. Looking carefully, find at least two confusing sections. This may be at the word, sentence, or paragraph level, perhaps an incorrect word or odd punctuation. The sentences might be awkward or too long. Even if the confusion clears up later, describe where the sections are and explain why they are confusing. The first confusing section is the second paragraph. The content of the paragraph does not flow correctly. First you were discussing the contemporary phone companies and about the new technology of telephones, and then you jumped into the historical development about Graham’s invention of the telephone.

In this this essay I relate his argument on language to â€Å"Darmok†, an episode of Star Trek: The Next Generation, and argue whether or not the alien species as depicted would have been able to achieve advanced technological capabilities.

WarGames Essay Example | Topics and Well Written Essays - 500 words

WarGames - Essay Example His latest goal is to discover how to get into the computers at a gaming company to play their latest big game before it comes out, but he unwittingly ends up inside WOPR, the top defense computer the Pentagon has at its disposal. Presented with a list of games to play, David is especially intrigued by one entitled, "Global Thermonuclear War", a simulation of US vs. Russia nuclear war scenarios. Alas, what started out as a game seems all too real, as WOPR takes over the systems at the NORAD project, and the folks there aren't sure if it is all a game or if the Russian missiles that appear to be poised to wipe out the US means World War III is imminent. Although WarGames is mostly considered a juvenile sci-fi adventure today, it was taken very seriously at the time of its release, thanks to the prevailing fear of nuclear war, in addition to the vast majority of the public not knowing of how such things as modems and computer actually work.

New York Times Essay Example for Free

New York Times Essay The newspaper serves as the first draft of history and is the most important source of primary documents in which historians use in order to better gauge exactly what were the concerns and motivations of a specific age. In 1900, America was celebrating a new century although there was little to celebrate. The Boar War in South Africa was taking far too long and costing far too many money and lives in what was perceived to be an invincible British Empire. A massive explosion in West Virginia killed dozens of miners and in China, the Boxer Rebellion; a Chinese nationalistic movement in which all foreigners were sought after and either expelled from the country or killed, was causing international headaches for America and President McKinley. The December 24, 1900 issue of the New York Times, the most prestigious newspaper in the country, detailed many of the aforementioned events as well as the smaller stories which never did make the history books but were vitally important for those who were involved. As 1900 was coming to a close and moving into what would be the bloodiest century in human history, the readers of that day, saw a world with no shortage of pessimistic news and depressing facts about the state of their world. In the backdrop of the Christmas season, the concern of the people of New York, as detailed in this issue of the New York Times, were detailing the hatred and strife which much of the world, and especially New York City had, in the day before Christmas.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The most important international issue of this day was the Boar War.   America would remain neutral in this war but with British soldiers deep in the heart of South Africa and fighting a war, the details commanded a position on the front page. The headline in the top left corner of page 1, â€Å"Boars Take British town,† detailed the pursuits of the British army in relation to the Boar War, which was ending its second year with no sign of victory. The war would continue from 1899-1902 and cost more lives and money than would ever have been conceived and historians marked this as the beginning of the end of the British Empire.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There were other important issues of the day. One issue which the people of New York were talking about that day was the firing of District Attorney Garnier by then governor Theodore Roosevelt. This story was seen on page 1 of the Times as well as a detailed editorial on page 6 of the paper. Theodore Roosevelt was seen as a free thinking Progressive Reformer who had no use for patronage, nor public opinion dictating his actions. He was one of the most unique Presidents this country ever had served in the White House. These aspects came through when Governor Roosevelt, under the idea that Garnier: â€Å"that he did not acknowledge the telegram of the governor directing attention to these officers†¦ and allowed his assets to interfere with the prompt trial of election cases.†[1] In other words, Garnier’s association with Tammany, the political force of the Democratic Party in which graft and patronage ran rampant, could not be separated from the demands of this office. In the election of 1900, it was asserted that Garnier had done little or nothing to stop the election tampering which the Republicans asserted had occurred. Governor Roosevelt believed this to be the case and promptly fired Garnier.   The New York Times, in their editorial, criticized this move, through the professed to be no friend of Garnier. â€Å"We think that the people’s rights and not Garnier’s are infringed by the action of Governor Roosevelt and are forced to condemn that action as a blunder in the nature of a crime.†[2] Tammany, since the days of Boss William Tweed, had been under a suspicion of grafting politicians and Roosevelt, always the reformer, sought to free New York City from the patronage which he felt was choking the lifeblood from the city. Tammany had been a source of patronage for decades and it sometimes served as the only source of employment for immigrants who were being ignored by the establishment. However, Tammany always ran under a cloud of suspicion for corruption and the reform candidates of that age, sought to starve Tammany of patronage. It is also interesting to note that since Governor Roosevelt was causing so much trouble, for both the Democrats as well as the Republicans, that he was placed on the Republican ticket as President McKinley’s Vice President in 1900 only a few months earlier as a way to silence him. Little did they know that the assassination of President McKinley in September 1901, propel Roosevelt onto the world political stage for the next 7  ½ years.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The newspaper also details the stories which never did make the history books. There are many one or two paragraph stories which served as life changing for those involved but which were quickly forgotten in a day or two by the rest of the public. One such story is of five year old Marie Horen who went into convulsions when she drank a bottle of whiskey as she copied what she had seen her father doing. She was rushed to the J. Hood Wright Hospital where her condition was deemed serious. Another story involves nine year old Nathan Roth who was shot in the head by one who the paper deemed crazy. He was shot in the head and the bullet exited the right eye of the boy. The boy was pronounced dead and the defendant, John Galletus, a father of three and one who had attempted to shoot others, was captured and sent away.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Another negative aspect of this day in New York History was the number of fires that were reported. There was listed, sixteen fires that had occurred. One of these fires ripped through a tenement in which it was reported that there presumed to be, a number of victims but as the records of those living in these tenements were sketchy at best, it seems as though the exact count will never be known. It has been suspected that a number of these fires, especially the ones in which barns were being set ablaze, was suspected of being done by a group of sixteen years from the many notorious gangs which New York City housed.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   It was also reported that Andrew Carnegie, the steel magnate, one who had originated from Scotland and had made his fortunes in steel, donated $20,000 for the assembly of a new library at the all black Tuskegee School in which Booker T. Washington founded and led. During these last years of his life, Carnegie sought o give away millions of dollars in the construction of libraries all across the country; from the large cities in America, to the small towns. He had earned his money through the ruthless exploitation of capitalism and now sought to right his wrongs and become a philanthropist and give money to support a new school at Tuskegee. This occurred at a time when only four years later, calls of treason arose from the South when President Roosevelt invited Booker T. Washington, a leader in the African American community to lunch in order to discuss the issues of the day concerning African Americans. It was reported that the entire building would be built from the hard work of the students themselves; a practice which had been adhered to when the school was first built. This speaks to the social culture of the day and is in contrast to the arrest of Ed. Johnson, a â€Å"dark† man who was suspected of kidnapping a woman. The story states, on page 1, that Mr. Johnson had been identified by a child witness as not having been the suspect but which did little to dissuade the authorities to immediately free Mr. Johnson.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Since this issue was dated Christmas Eve, there is also a religious aspect to this day as millions of Christians in the city were set to celebrate the birth of Jesus. This aspect of loving one’s neighbor which is seen more often around Christmas time than any other, was seen in a large advertisement which detailed the Salvation Army’s feeding of the poor as well as the performance of a passion play. These plays were designed to detail the last hours of Jesus before he was hung on the cross. These plays have served as a popular and touching aspect of the Christmas Season but which have become more popular during the Easter season. In this spirit of alms giving, the New York Protestant Episcopal Society was also feeding Christmas dinner to the poor. However, with New York City containing a large Jewish population, it was stated by the prominent rabbis of the city, that the Jewish people can enjoy this Christmas season, the joy and fulfillment which their fellow New Yorkers are experiencing this Christmas season but that Jews should be careful not to blend their appreciation for the enjoyment of others, with their own sense of faith, which it was stated, â€Å"has fundamental and final differences between Judaism and Christianity.†[3]   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   1900 was an important and event-packed year. Reading the newspapers, specifically the New York Times, serves as a reminder that ever day, there occurs events, large and small, important and socially irrelevant, that occur every day and which are important to the people it affects. In a city as large as New York City, there still occurs individual interest stories like the death of nine year old Nathan Roth or the case of five year old Maggie Enloin who went into convulsions after drinking a bottle of whiskey after seeing her father do the same. These stories occur every day, in every part of the country, as well as the world. Many times, they are not reported but in this day, December 24, 1900, the editors of The New York Times, felt that the tragic death of a nine year old to street violence, or the burnings of tenements on the Lower East Side, as well as the involvements of the Boxer Rebellion, the Boar War or the issues of patronage and corruption within the Tammany machine, all fell under the definition: â€Å"All the news that is fit to print.† This day in American History as well as New York History, saw a wide array of human interest stories, coupled with heavy issues and the larger questions of: â€Å"What role will political patronage serve in the city and how much damage can Governor Roosevelt make before he assumes the Vice Presidency? Are the problems of the tenements to only being reported or sill any actions are made to help the poor and to help them rise above their circumstance? Can the deaths of innocent children be reconciled in a city who believes that it is on the cutting edge of the country’s reforms? Also, to what degree, if any, will America get involved in the issues overseas such as the Boar War and the Boxer Rebellion and how their outcomes will affect America’s relations with these countries. The December 24, 1900 issue of the New York Times, had contained within its twelve pages, a wide array of stories from all walks of life and on all levels of importance. Many of the above mentioned people are to be remembered, when they are remembered at all, in the pages of the newspaper: the first draft of history.

Hospital Web Application Design for Elderly Patients

Hospital Web Application Design for Elderly Patients The aim of this project is to develop an elderly friendly web application which can be used to book hospital appointments online and also interact with Doctors via skype. It also can be used by doctors to maintain patient records which can be given read access to patients to their records. This aim also needs us to answer few things and the first one would be to address the needs of ageing population in learning how to use a computer if they dont know already and also using a web application which would cater their needs and make their lives easy. We will also discuss the specific difficulties faced by the ageing population in learning computer skills which will in turn help them using a web application easily. Older adults and technology Health takes a down turn when a person gets old and in the future years the number of older adults are going to increase according to many statistics. This could lead to being hospitals and clinics overfilled and become more in demand. Due to several factors, older adults will need supervision in their health from proper health care practitioners (Codreanu Florea, 2016). Perception of control is one of the most important factors in determining ones place on a social environment. To keep up with the new technologies younger generation use older generation are learning new computer technology faster than the younger generation (Morrell, 2002). To avoid themselves from socially isolating in this day and age older adults learn computer skills and also learn how to use internet. And some even contradict Morrell saying that older adults learn computer skills slower due to physiological changes which makes their learning process slow. Older adults can integrate with the modern society by learning how to use new technology and also know how to learn new stuff from internet on their own. There are many E-learning programs which can be used by the ageing population to learn anything. Most of the times older adults make the government of a country to to question its own policy towards people working after they retire. In the same way, they should also be able to integrate with the rest of the society to use latest web applications which are in the market and adapt to them and for them to adapt to it, the application creators should focus that there are plenty of older adults as well who might use their application in a day to day basis. To dive deep into the discussion of why web applications should be older adult friendly we will discuss the myths around older adults using web applications, how older adults are engaging themselves in learning latest technology and also the obstacles they face in using a web application (Githens, 2007). The goal of this project is to focus on the guidelines to be followed which can make the older adults involve in using web applications and also focus on other opportunities related to it in the favor of older adults and companies which develop web applications. How retirement is changing? Life expectancies have been increasing which has also increased the retirement years proportionally. Due to this the older adults value, all the benefits they get from employment after retirements such as financial, social, physiological and many more. Those employments may be full-time, part-time, paid, unpaid or even a temporary employment (Hale, 1990). With this and also seeing organizations dealing with new talents due to reduction of experienced workers due to retirement we could say that retirement is an outdated concept (Stein and Rocco, 2001). With the research done in the past decade it is seen that the new talents also want to be working after they retire, which is about 80% in 2005 (Dychtwald, 2017). With this spirit the notion of retirement will be transformed in the future as these new talents are the ones which bring big changes in the current world. The world-wide web or as we call the internet is not just for the younger generation. With many new applications like Quora, Facebook and many more we have seen that the internet is accepting individuals all around the world irrespective of the age and it is also seen that there has been an increasing number in the people of older age group. To determine the exact number would be difficult as any precise number which comes up will be obsolete after it gets recorded.

malcolm x Essay -- essays research papers

Malcolm X was a very interesting and complicated person. Throughout his life, Malcolm had exposure to practically every type of person the world had to offer. In his younger years, he excelled in his community predominately surrounded by whites. He then got into the hustling business within the black community which supplied for all types of people. After that, he joined the Nation of Islam, joining himself with many Muslims. Lastly, Malcolm went on a Hajj to Africa, where his communication with a diverse group of people expanded. Each time Malcolm had a new group of people in his life, he had a different alias to go by. Whichever one is remembered most, Malcolm Little, Malcolm X or El-Hajj Malik El-Shabazz, his impact on society will be remembered forever.   Ã‚  Ã‚  Ã‚  Ã‚  Gaining information on Malcolm from two different â€Å"texts† really helped in my understanding of him. These two different â€Å"texts† were The Autobiography of Malcolm X and the film Malcolm X: Make it Plain. Both of these pieces were informative in two entirely different ways. In the book, we gained knowledge of Malcolm through his views on various aspects of life. However, in the movie, we gained knowledge of Malcolm from others’ points of views. For me, the film was more helpful because I am more of a visual learner.   Ã‚  Ã‚  Ã‚  Ã‚  Malcolm Little, his birth name, was a very gifted child growing up. He managed to receive straight A’s and become the president of his junior high school. The book got more in depth than the movie in that aspect of his life. For example, the book talked about how Malcolm told his English teacher, Mr. Ostrowski that he wanted to become a lawyer. Even though this teacher encouraged the less intelligent white students to aspire any dreams, he told Malcolm that he would be better off becoming a carpenter. That was a very important part in Malcolm’s young life. It can be considered the turning point of his views with the white community. The movie would not be able to fit all of the information of his childhood that the book displayed. The film gave us an insight on how his brothers and sisters saw life as a young child around Malcolm, a time I am sure they will not forget.   Ã‚  Ã‚  Ã‚  Ã‚  Now Malcolm became a hustler on the streets of Harlem, needless to say, that occupation did not last very long. The book gave many details... ...ms felt threatened by Malcolm, he foresaw his own death, stated in both â€Å"texts.† Both pieces told how Malcolm was murdered, but the film was more emotional, because it let us view where the shooting occurred, with people’s views of the incident.   Ã‚  Ã‚  Ã‚  Ã‚  In contrast, the book could not let the reader know everyone’s reactions to this unfortunate death. In the film, we are made aware that both of Malcolm’s brothers, Philbert and Wilfred did not attend his funeral because of the precautions of their own safety. Also, we could see and hear the emotion that people felt when he was assassinated. Another interesting fact obtained from the movie was coincidentally the name of the film; Make it Plain. Prior to coming out to speak, Malcolm always told the speaker before him to â€Å"make it plain† implying that he did not want any special introduction. His half sister, Ella Collins, still goes to bed every night with the idea that â€Å"one day I’ll get even.† Finally, the book failed to show that when Malcolm was buried, his followers shunned away the professional grave diggers to dig up his grave themselves. That alone shows the effect this man had on all that he encountered.

Kidney Thieves Urban Legend :: Urban Legends

Losing Organs at a Party: The "Kidney Thieves" Legend and the Immigrant Experience My family, most being first generation immigrants, has at times a slightly negative view of American culture. Because of this, many of the family dinner conversations are about the differences between American and Iranian cultures and often how the Iranian culture is better in some ways. To support this theory many urban legends are brought up that show the â€Å"dark side† of the American culture. For example, when the family was gathered together for the Iranian new year, a version of the famous legend about the traveler who was drugged and robbed of his organs in a hotel room was told by a family member. It is important to note that he told the story in Farsi, which means that I am translating and not merely re-telling the story verbatim. The storyteller's version of the story was about an Iranian foreign exchange student who had recently come to the US. The story begins with the student, being alone in this country, going to a party he had heard of from other students. In the party, having had a few drinks, another â€Å"American thing† my family is against, he met a beautiful innocent girl who offered him a drink and asked to go to his place at the end of the night. The tone with which he described the girl was specially interesting, noting that even the innocent looking girls cannot be trusted. The story goes that the Iranian student did not remember anything from that point on until he woke up the next day in his bathtub covered with ice. There was also a note next to him telling him not to move and call 911. When the ambulance arrived at his apartment he was told that his kidney was removed and that he was not the first person this has happened to. To add to the accuracy and suspense of the story, the stor yteller, a physician, mentioned how the ice was used to keep the student’s body cold to prevent excessive blood loss and inflammation, which was essentially what kept him alive. After being discharged from the hospital for a few weeks with a missing kidney, a big hospital bill, and having fallen behind his studies, the student found out that there is an organized ring of organ thieves who specialize in lonely foreign students, who are as the storyteller sees it, more susceptible to being seduced by girls.

Back to the Future: the Work and Influence of Filippo Marinetti & Umberto Boccioni

Back to the Future The work and influence of Filippo Marinetti & Umberto Boccioni In Europe the transition from the 19th to the 20th century witnessed the emergence of a number of artistic and social movements which left a great impact on societies, not only in Europe but also worldwide. Movements such as Futurism, Dadaism, Surrealism, and Constructivism played an important role in changing society for the better by using their design and art practices.This era also witnessed a number of ideological and cultural changes in many fields such as psychology, philosophy, arts, and technology. Behind the popularity of Dada, Surrealism, Constructivism, Art Deco, and also Vorticism, there was a strong idea of Futurism which incorporated elements of technology, speed, violence, and mechanical objects such as cars, airplanes, and bicycles. Futurism was largely an Italian based movement, however there were other versions of the movement happening around the world, including Russia, and England. .Most Futurists practiced in various mediums of art. According to Anonymous (2010), sculpture, painting, architecture, ceramics, industrial design, interior design, graphic design, theatre and film, textiles, and literature were all acceptable mediums for The Futurists. Two of the more notorious Futurists were Filippo Marinetti, and Umberto Boccioni. Marinetti’s Manifesto of Futurism and Boccioni’s plastic dynamism and sculpture, Unique Forms of Continuity in Space are two very well known pieces of art which played an important role in the popularity of Futurism.The works of the two futurists inspired many artists of their time and are still well known amongst contemporary artists. When the French newspaper, Le Figaro, published on its front page a manifesto about an artistic group, no one knew about the author. The manifesto was written by an EgyptianItalian named Filippo Marinetti, who was based in Milan and was one of the founding fathers of Futurism. The literary p iece was about Le Futurism, the foundation manifesto of the artistic group which was in the process of forming. Marinetti was a natural born writer he wrote from a very young age.He studied in Paris, where he furthered his love for literature. Marinetti’s rebellious nature caused him some difficulties even at this age. He faced the threat of expulsion when he tried to publish Emile Zola’s scandalous novels through the school magazine. (Harrison 2003, 35) Shortly after the manifesto was published Marinetti was thrust into the public eye, gaining notoriety amongst his contemporaries who saw that he would introduce large changes in the art world. However he was severely criticized by some artists because of his passionate hate for old art and politics.In the article, Marinetti idealized the beauty of modern life and discussed the benefits of machinery, speed, violence, and youth. He talked about the transformation of Italian culture in a new artistic world. According to H enning (2006), Marinetti’s manifesto was not welcomed by most historians who saw it as an attack against history, and historicism. They were of the view that Marinetti joined anti-musuem sentiment with nationalism. Even though the manifesto was published in a French newspaper, it received a large response from Italy. The manifesto was published in the French newspaper Le Figaro, but he emphasized its source -’from Italy’- at the same time as he rejected the museum culture of Italy, and by implication France too, in the effort to pronounce himself of the present, and of the future. Marinetti associated museums with an obsessions with the past which was corrupting and infecting the body of the nation. † (Henning 2006, 39) Marinetti’s manifesto continued to gain popularity from contemporary artists and draw criticism from contemporary historians.His opposition to museums were considered a threat to the connection between ancient art and literature. In 1916, when Marinetti introduced the manifesto ‘The New Religion-Morality of Speed’, it was clear that it had some connection with the past. Though Marinetti adorned this manifesto with technological excitement, he used the parody of religious language, which confused his critics. ‘The New Religion’ has received a strong response from authors over time. For example Blum (1996) see in the manifesto a strong logic for Futurism. The binary structuring of reality is tied to the founding of a new religion. In ‘La nuova religione-role della velocita’ (The New Religion-Morality of Speed; 1916), Marinetti argues that speed, whose essence is ‘the intuitive synthesis of all forces in movement,’ is, by nature, pure. † (Blum 1996, 34) Despite a strict Catholic upbringing, Marinetti was an open opponent of religion, especially the influence of The Vatican in Italy. He was greatly influenced by his fathers interest in the history of religio n. He had great command of the use of religious language, but always with an anti-clerical tone.For example, in his manifesto, ‘Against the Papacy and the Catholic Mentality, Repositories of Every Kind of Traditionalism’, Marinetti launched a campaign for the liberation of Italy from The Vatican. Despite there being clear anti-Catholic tirades in his two manifestos-Against Spain, and Against the Papacy and the Catholic Mentality- one can easily find a solid religious foundation within his writings. Bru and Martens (2006) see a connection between the manifestos. They are of the opinion that despite a gap of over nine years between the publication of the two manifestos, little change is seen in his views of religion. Marinetti expressed his anti-Catholic sentiments in the manifestos, Against Spain (1910) and Against the Papacy and the Catholics Mentality, Repositories of Every Kind of Traditionalism (1919). He was fervently supported by Settimelli, whose brochure Svatican amento: Dichiarazione agli italiani, attacked the Vatican in such strong term that it was sequestered and its author taken to court. † (Bru and Martens 2006, 179) Berghaus (2009) has found genuinely innovative elements in the manifestos of Marinetti. He is of the opinion that Marinetti’s manifestos propagate the futurist reform of lifestyle. Marinetti was opposed to any fetishization of the muscular body and was highly critical of the Fascist adoption of sporting spectacles for the purpose of indoctrination. He was interested in healthy bodies with agile minds. Modern physical culture was an ally in his battle against decadence, materialism, and outdated values. † (Berghaus 2009, 33) Therefore, it can be said that the hidden religious characteristics of Marinetti helped to construct his anti-Catholic and anti-clerical campaign. It is obvious that he developed this quality because of his father’s close connection with religion and religious symbolism.Marinet ti’s role in giving a significant position to Futurism in the cultural history of the twentieth century cannot be ignored. Italian painter and sculptor Boccioni is considered to be one of Italy’s most important Futurists. He laid a strong foundation for the concept of Futurism in Italy. Boccioni, who studied art in Rome’s Scuola Libera del Nudo a the Accademia dil Belle Arti, launched a campaign in 1914 to transform Italy, and introduce Plastic Dynamism. His encounter with Futurism came after many years of studying the psychology of artistic dilemmas.He used powerful plastic forms to convey a concept of movement both intrinsic and relative to the object’s environment. After studying the Impressionists and Post-Impressionists in Paris. Boccioni played a very important role in the establishment of Futurism in Italy in 1911. This was time when Futurism had formed an idiosyncratic and vibrant style, with earl stages of pointillism giving way to a softer, less distinct neo-impressionisitic aesthetic. Smith (1997) says that because of Boccioni’s stern anti-traditional notions, researchers often find a similarity between himself and Marinetti’s ideologies.The response of the two Futurists towards tradition and the influence of religion on society in Italy is very similar indeed. However, according to Smith, Boccioni is differs slightly in his ideas about modernism. â€Å"Although most writers on Futurism accept that Boccioni was caught up by Marinetti’s ideology, most have isolated his work from his proto-Facist politics. His work is thus discussed primarily in terms of his use of the formal devices for the representation of modernity that the Futurists advocated in their manifesto; theories of modernism and various forms of contemporary philosophy are also invoked. (Smith 1997, 111) Like Marinetti, Boccioni audaciously attacked traditional values in his book ‘Pittura e scultura futuriste (dinamismo plastico)â⠂¬â„¢. He announced that his ideas n Plastic Dynamism would function as an anti-traditional idea, and revive not only Italy, but the whole world. In plastic dynamism, Boccioni tried to find a connection between plastic form, and it’s surrounding space. Boccioni has received great attention from Hays (2000) who has closely researched the development of Plastic Dynamism.The author gives credit to Boccioni in the development of new theories in the genre. â€Å"A more essential evolution of these problems, and one closer to the scientific movement that emancipated physical theory from the old notion of matter and its correlative space, is the basis of the new plastic theories developed by the Futurist Umberto Boccioni in his writings on Plastic Dynamism. † (Hays 2000), 592) Boccioni, in his writing severely criticized the traditional aesthetic taste of a democratic states, and said they were largely comprised of pseudo-intellectuals, anarchists, and socialists.He held Enri co Ferri, the socialist editor of L’Avanti in high regard, but was also supportive of Enrico Corradini, the nationalist novelist and journalist. Despite Boccioni’s criticism of the Italian Nationalist Association for it failure to assist the futurists in promoting the movement politically, he was of the view that Corradini’s nationalist beliefs were a beacon of hope in a corrupt society. Boccioni studied closely both the nature of an object in motion and its visual revolution in relation to the environment through which it travels.Contrary to traditionalists, his plastic dynamism was a regeneration of plastic consciousness which rejected the devastating effects of democratic-rationalist education. (Kwinter, 2001, 61) Therefore it would not be wrong to say that the aesthetics of Plastic Dynamism which Boccioni highlighted in his writing was anti-democratic as well as anti-traditional. According to Harte (2009), Boccioni, despite his inspiration from the Avant Gar de art movements of Picasso and Braque, presented his ideas in a different style. Unlike the cubists, Picasso and Braque, who fragmented the painted object with little regard for its relationship to the surrounding world, Boccioni and his fellow futurists emphasized an aestheticised object’s interaction with that world, regarding this interaction as critical to a successful expression of rapid movement on the static canvas or through three dimensional, sculpted forms. † (Harte 2009, 18) Boccioni’s understanding of the fourth dimension successfully bound the theory of space to a temporal idea of revolution.This understanding makes Boccioni prominent amongst other Futurists. The study of the work and writings of both Boccioni and Marinetti make it clear that without an understanding of these two figures, it is difficult to understand the concept of Futurism itself. These two Futurists played an important role in sparking people’s interest in the Futurist mov ement, created a template not only for artistic ideas, but also for cultural and social disobedience and a fundamental opposition to traditional aesthetic, moral and political opinions.They each attempted to clarify the Futurist’s ideals and their work left a great impact on society. Smith (1997) provides further evidence of the ideological connection between Boccioni and Marinetti. â€Å"Boccioni and Marinetti founded a movement based on speed. With the death of it’s leading artists, Boccioni, Futurism died fast. † (Strickland and Boswell 2007, 139) References Anonymous (2010) Futurism: Futurist Manifesto, Suite Vollard Enrico Prampolini, General Books LLC, New York Anonymous Berghaus, G. 2009) Futurism and the Technological Imagination, Rodopi, Amsterdam Blum, C S.

Behind the popularity of Dada, Surrealism, Constructivism, Art Deco, and also Vorticism, there was a strong idea of Futurism which incorporated elements of technology, speed, violence, and mechanical objects such as cars, airplanes, and bicycles. Futurism was largely an Italian based movement, however there were other versions of the movement happening around the world, including Russia, and England. .Most Futurists practiced in various mediums of art. According to Anonymous (2010), sculpture, painting, architecture, ceramics, industrial design, interior design, graphic design, theatre and film, textiles, and literature were all acceptable mediums for The Futurists. Two of the more notorious Futurists were Filippo Marinetti, and Umberto Boccioni. Marinetti’s Manifesto of Futurism and Boccioni’s plastic dynamism and sculpture, Unique Forms of Continuity in Space are two very well known pieces of art which played an important role in the popularity of Futurism.The works of the two futurists inspired many artists of their time and are still well known amongst contemporary artists. When the French newspaper, Le Figaro, published on its front page a manifesto about an artistic group, no one knew about the author. The manifesto was written by an EgyptianItalian named Filippo Marinetti, who was based in Milan and was one of the founding fathers of Futurism. The literary p iece was about Le Futurism, the foundation manifesto of the artistic group which was in the process of forming. Marinetti was a natural born writer he wrote from a very young age.He studied in Paris, where he furthered his love for literature. Marinetti’s rebellious nature caused him some difficulties even at this age. He faced the threat of expulsion when he tried to publish Emile Zola’s scandalous novels through the school magazine. (Harrison 2003, 35) Shortly after the manifesto was published Marinetti was thrust into the public eye, gaining notoriety amongst his contemporaries who saw that he would introduce large changes in the art world. However he was severely criticized by some artists because of his passionate hate for old art and politics.In the article, Marinetti idealized the beauty of modern life and discussed the benefits of machinery, speed, violence, and youth. He talked about the transformation of Italian culture in a new artistic world. According to H enning (2006), Marinetti’s manifesto was not welcomed by most historians who saw it as an attack against history, and historicism. They were of the view that Marinetti joined anti-musuem sentiment with nationalism. Even though the manifesto was published in a French newspaper, it received a large response from Italy. The manifesto was published in the French newspaper Le Figaro, but he emphasized its source -’from Italy’- at the same time as he rejected the museum culture of Italy, and by implication France too, in the effort to pronounce himself of the present, and of the future. Marinetti associated museums with an obsessions with the past which was corrupting and infecting the body of the nation. † (Henning 2006, 39) Marinetti’s manifesto continued to gain popularity from contemporary artists and draw criticism from contemporary historians.His opposition to museums were considered a threat to the connection between ancient art and literature. In 1916, when Marinetti introduced the manifesto ‘The New Religion-Morality of Speed’, it was clear that it had some connection with the past. Though Marinetti adorned this manifesto with technological excitement, he used the parody of religious language, which confused his critics. ‘The New Religion’ has received a strong response from authors over time. For example Blum (1996) see in the manifesto a strong logic for Futurism. The binary structuring of reality is tied to the founding of a new religion. In ‘La nuova religione-role della velocita’ (The New Religion-Morality of Speed; 1916), Marinetti argues that speed, whose essence is ‘the intuitive synthesis of all forces in movement,’ is, by nature, pure. † (Blum 1996, 34) Despite a strict Catholic upbringing, Marinetti was an open opponent of religion, especially the influence of The Vatican in Italy. He was greatly influenced by his fathers interest in the history of religio n. He had great command of the use of religious language, but always with an anti-clerical tone.For example, in his manifesto, ‘Against the Papacy and the Catholic Mentality, Repositories of Every Kind of Traditionalism’, Marinetti launched a campaign for the liberation of Italy from The Vatican. Despite there being clear anti-Catholic tirades in his two manifestos-Against Spain, and Against the Papacy and the Catholic Mentality- one can easily find a solid religious foundation within his writings. Bru and Martens (2006) see a connection between the manifestos. They are of the opinion that despite a gap of over nine years between the publication of the two manifestos, little change is seen in his views of religion. Marinetti expressed his anti-Catholic sentiments in the manifestos, Against Spain (1910) and Against the Papacy and the Catholics Mentality, Repositories of Every Kind of Traditionalism (1919). He was fervently supported by Settimelli, whose brochure Svatican amento: Dichiarazione agli italiani, attacked the Vatican in such strong term that it was sequestered and its author taken to court. † (Bru and Martens 2006, 179) Berghaus (2009) has found genuinely innovative elements in the manifestos of Marinetti. He is of the opinion that Marinetti’s manifestos propagate the futurist reform of lifestyle. Marinetti was opposed to any fetishization of the muscular body and was highly critical of the Fascist adoption of sporting spectacles for the purpose of indoctrination. He was interested in healthy bodies with agile minds. Modern physical culture was an ally in his battle against decadence, materialism, and outdated values. † (Berghaus 2009, 33) Therefore, it can be said that the hidden religious characteristics of Marinetti helped to construct his anti-Catholic and anti-clerical campaign. It is obvious that he developed this quality because of his father’s close connection with religion and religious symbolism.Marinet ti’s role in giving a significant position to Futurism in the cultural history of the twentieth century cannot be ignored. Italian painter and sculptor Boccioni is considered to be one of Italy’s most important Futurists. He laid a strong foundation for the concept of Futurism in Italy. Boccioni, who studied art in Rome’s Scuola Libera del Nudo a the Accademia dil Belle Arti, launched a campaign in 1914 to transform Italy, and introduce Plastic Dynamism. His encounter with Futurism came after many years of studying the psychology of artistic dilemmas.He used powerful plastic forms to convey a concept of movement both intrinsic and relative to the object’s environment. After studying the Impressionists and Post-Impressionists in Paris. Boccioni played a very important role in the establishment of Futurism in Italy in 1911. This was time when Futurism had formed an idiosyncratic and vibrant style, with earl stages of pointillism giving way to a softer, less distinct neo-impressionisitic aesthetic. Smith (1997) says that because of Boccioni’s stern anti-traditional notions, researchers often find a similarity between himself and Marinetti’s ideologies.The response of the two Futurists towards tradition and the influence of religion on society in Italy is very similar indeed. However, according to Smith, Boccioni is differs slightly in his ideas about modernism. â€Å"Although most writers on Futurism accept that Boccioni was caught up by Marinetti’s ideology, most have isolated his work from his proto-Facist politics. His work is thus discussed primarily in terms of his use of the formal devices for the representation of modernity that the Futurists advocated in their manifesto; theories of modernism and various forms of contemporary philosophy are also invoked. (Smith 1997, 111) Like Marinetti, Boccioni audaciously attacked traditional values in his book ‘Pittura e scultura futuriste (dinamismo plastico)â⠂¬â„¢. He announced that his ideas n Plastic Dynamism would function as an anti-traditional idea, and revive not only Italy, but the whole world. In plastic dynamism, Boccioni tried to find a connection between plastic form, and it’s surrounding space. Boccioni has received great attention from Hays (2000) who has closely researched the development of Plastic Dynamism.The author gives credit to Boccioni in the development of new theories in the genre. â€Å"A more essential evolution of these problems, and one closer to the scientific movement that emancipated physical theory from the old notion of matter and its correlative space, is the basis of the new plastic theories developed by the Futurist Umberto Boccioni in his writings on Plastic Dynamism. † (Hays 2000), 592) Boccioni, in his writing severely criticized the traditional aesthetic taste of a democratic states, and said they were largely comprised of pseudo-intellectuals, anarchists, and socialists.He held Enri co Ferri, the socialist editor of L’Avanti in high regard, but was also supportive of Enrico Corradini, the nationalist novelist and journalist. Despite Boccioni’s criticism of the Italian Nationalist Association for it failure to assist the futurists in promoting the movement politically, he was of the view that Corradini’s nationalist beliefs were a beacon of hope in a corrupt society. Boccioni studied closely both the nature of an object in motion and its visual revolution in relation to the environment through which it travels.Contrary to traditionalists, his plastic dynamism was a regeneration of plastic consciousness which rejected the devastating effects of democratic-rationalist education. (Kwinter, 2001, 61) Therefore it would not be wrong to say that the aesthetics of Plastic Dynamism which Boccioni highlighted in his writing was anti-democratic as well as anti-traditional. According to Harte (2009), Boccioni, despite his inspiration from the Avant Gar de art movements of Picasso and Braque, presented his ideas in a different style. Unlike the cubists, Picasso and Braque, who fragmented the painted object with little regard for its relationship to the surrounding world, Boccioni and his fellow futurists emphasized an aestheticised object’s interaction with that world, regarding this interaction as critical to a successful expression of rapid movement on the static canvas or through three dimensional, sculpted forms. † (Harte 2009, 18) Boccioni’s understanding of the fourth dimension successfully bound the theory of space to a temporal idea of revolution.This understanding makes Boccioni prominent amongst other Futurists. The study of the work and writings of both Boccioni and Marinetti make it clear that without an understanding of these two figures, it is difficult to understand the concept of Futurism itself. These two Futurists played an important role in sparking people’s interest in the Futurist mov ement, created a template not only for artistic ideas, but also for cultural and social disobedience and a fundamental opposition to traditional aesthetic, moral and political opinions.They each attempted to clarify the Futurist’s ideals and their work left a great impact on society. Smith (1997) provides further evidence of the ideological connection between Boccioni and Marinetti. â€Å"Boccioni and Marinetti founded a movement based on speed. With the death of it’s leading artists, Boccioni, Futurism died fast. † (Strickland and Boswell 2007, 139) References Anonymous (2010) Futurism: Futurist Manifesto, Suite Vollard Enrico Prampolini, General Books LLC, New York Anonymous Berghaus, G. 2009) Futurism and the Technological Imagination, Rodopi, Amsterdam Blum, C S.
