Disparity and Discrimination

Criminal Justice System has long been established in order to guide all law enforcers and legal officers in the implementation of laws and order in achieving justice. The law provides for strict prohibition of any signs of unfairness. However, the system is faced with issues of disparity and discrimination that continues to cast doubt as to the implementation of the law. Disparity refers to the â€Å"idea that individuals who commit the same or similar offenses receive different punishment† (Justice Works, 2008).Discrimination, on the other hand, refers to the â€Å"act of singling out a certain individual or group fro unfair treatment based on race, class, gender, or status† (Calderon). In criminal justice system, both disparity and discrimination are illegal. While disparity may not be intentional it is always unacceptable in the system. Discrimination, on the other hand, is always done intentionally.In addition, disparity is concern with the differences in outcome wh ile discrimination deals with equal treatment (Gelsthorpe and Padfield, 2003, p. 4). In criminal justice, disparity has been apparent in the juvenile proceedings. According to research, more juvenile minorities have been detained in public secure facilities while whites were housed in private secure facilities (Snyder and Sickmund, 1995). In addition, discrimination is also prevalent because of different treatment afforded to blacks and whites.Disparity usually occurs when more blacks were detained than whites who had committed same crime. Discrimination, on the other hand, occurs when detention of black was based on his race. In avoiding disparity, it is necessary that the legal factors such as seriousness of the crime and criminal history should be considered in the decision making (Calderon). Discrimination may also be avoided by implementing the law equally. References Calderon, M. (04 September 2006). AnairHoads. Org. Disparity and Discrimination.

Favorite Time of Year

A Little Christmas Dinner Christmas is the time of year renowned for bringing families together in a way no other holiday can quite muster up to. Family togetherness feels like a cup of hot chocolate on the first cold night of the year; heart warming. That magical day when relatives flock from all over to be in one house, at one table, and to eat one meal, nothing is more special than a little Christmas dinner. Christmas is known for coming quicker and quicker each passing year.Many people begin to silently panic as soon as they hear the first Christmas song on the radio. To me it strikes into my head that our yearly family Christmas dinner is ever so close. As a child I enjoyed the Christmas dinner but not for the wholesome heart warming reasons that echo through my words now, but for the greedy natured presents. Admittedly the presents still are a highlight of the Christmas dinner, but after a few seasoned years of learning that Christmas is not about materialistic items I now feel that the Christmas dinner is the best part of this day.Every year we have the dinner at my grand parent’s quant house in the country. It takes a few hours to get there, but the country ride is more mesmerizing than any movie that I have ever seen. The twists and turns on a single lane road surrounded by tree’s help set the tone for what the day will bring. Every year I am always the first one there to help my grandparents to set up. The first thing I always remember to do is hug each one of them for as long as I can, thankful for another year to take in their open arms.After the greetings I always help Grandpa with the yard, raking up the final of the fall leaves and stringing up a few lights on top of the house because the little cousins always look forward to it. Grandpa is a hard working man that refuses to retire and knows his best working days are behind him. It seemed like yesterday all of this work he could have done with his eyes closed. Knowing how much sense of pride he gets on his hard work and watching him stand there helpless unable to do any of the work reminds me cherish the moments we have together.Soon Grandpa would be too tired to do much more and I would hustle back into the house to find Grandma hard at work. She has just as much work ethic as Grandpa but is ten years younger so she still has that fire that seems to burn deep in all of the Little family. She is hustling away baking cakes and cooking the ham. Watching how hard she works gives me a greater sense of joy than any present that I could possibly receive on this day. The other family members begin to arrive group by group.The food is still not done and the cake still needs to be frosted, but I believe Grandma sets it up like that so my four and five year old cousins can lick the spoon. Everyone pitches in to help on the final sides and setting the table while having casual conversation. And just as fast as Christmas seemed to come it was time to sit down and enjoy th e famous Little Christmas Dinner. We all gather around the large mahogany table and join hands and pray. My Grandpa always leads us into a wonderful prayer that always seems to summarize how we as a family feel.After the prayer we all line up from youngest to oldest to gather a plate load of the best food we will have the rest of year. Everyone hurry’s to get a big helping of Grandma’s mashed potatoes because she always seems to never cook enough. After we have all placed as much food that our little styrofoam plates can handle the food disappears almost as quickly as it was put on the plate. As soon as the food seems to settle into everyone’s system that is when the true Christmas spirit seems to have hit. The joy on everyone’s face echoes my sentiments that this Little Christmas Dinner is what life is truly about.

It is known for its stimulating effect on the functions of the brain , thus making the drinker active . Variants of coffee flavors were already produced all throughout the world aiming for the discovery of alternative sources of coffee production . The coffee from ampalaya seeds help us to earn and save money . A. Background of the study Coffee alternatives have been famous since the last two decades due to economic crisis and experimentations for health and medical benefits. Any seeds that are edible when powdered can be used as an alternative source for coffee. The difference of the generic coffee from the seeds of the coffee plant from those of the alternatives is that it has a good amount of caffeine content. The similarity you can find in the alternatives and those of the original is that seeds contain carbohydrates which cause the aroma in roasted coffee. Ampalaya, on the other hand, is a crawling vine that grows mostly on tropical countries like the Philippines. It is said to be rich in iron, potassium, beta-carotene and other nutrients. It is also famous in treating diabetes because of its properties like polypeptide-P; a plant insulin that can lower blood sugar levels. Many researches on agricultural food chemistry convey that it provides nutritionally significant amounts of nutrients, minerals and amino acids that are needed for life. B. Objectives of the study B1. General Objectives 1. To determine if the ampalaya seeds have considerable characteristics of the products in terms of color, aroma, taste, and acidity. B2. Specific Objectives 1. To produce coffee using ampalaya seeds as the main ingredient. 2. To determine and compare the levels of acceptability of the coffee samples. C. Hypotheses NULL 1. There is no significant difference among the different ampalaya coffee samples developed in terms of their color, aroma, and taste. ALTERNATIVE 1. There is no significant difference among the different ampalaya coffee samples developed in terms of their acceptability. D. Significance of the study Momordica Charantia or ampalaya seeds contain iron and folic acid which are essential for the production of the red blood cells and the formulation of hemoglobin and myoglobin. Coffee is usually drunk hot, black or with cream and sugar and also drunk cold as iced coffee, specially summer. People are used of drinking coffee every morning to warmth their body and at night to avoid being sleepy. But coffee contains a stimulant called caffeine. The result of this will determine if the coffee made from ampalaya seeds can be use as a substitute for the commercial coffee. This study aimed to produce coffee using ampalaya seeds as substitute. The study was important because ampalaya is abundant in the Philippines. The product may be an anti-diabetes coffee but it is not the main concern of the study. Everybody can benefit of the result of the study unless a coffee drinker. It would recycle the ampalaya seeds instead of being thrown away which a lot of people consider it as waste. E. Scope and limitation The proposed study was limited to producing coffee out of ampalaya (Momordica charantia Linn. ) seeds. Three samples were prepared with different ampalaya seed concentration and same amount of water for comparison purposes in which one of the samples was pure commercial coffee. The samples were processed by the basic methods of making coffee: roasting, grinding, and brewing. Ampalaya Coffee. (2017, Mar 08).

Contemporary Issues In Marketing Essay Example | Topics and Well Written Essays - 2500 words - 2

Contemporary Issues In Marketing - Essay Example Though the customers perceive the whole thing as a single offering but actually customers reacts differently to each element of the marketing mix. If each part of the marketing mix acts differently and contradicts each other, then it creates an ambiguous effect that makes the customers behave in a confused manner and they tend to purchase product from other companies who have defined brands (Foxall, 1981). The method of marketing mix is used by the marketing manager to produce optimal response in the target market. By creating a perfect blend of the marketing mix elements such that they are utilized in an optimum way. All the elements in the marketing mix are controllable variable and can be altered to meet the need of the target market and the environment. Hence marketing mix is most useful tool to design the strategy and achieve success in the target market (Bootwala, Lawrence and Mali, 2009; Botha, Bothma and Brink, 2005). This study focuses on the use of the marketing tool for a restaurant chain in London that aims to generate a positive experience for the customers. Marketing Mix for the service chain The marketing mix for the service industry deals with the 7P’s like product, price, place, promotion, people, process and physical evidence. Product The package or product in the service industry is seen as a bundle of benefits and features, which has a close relevance to the target market. This makes it important to develop the service product or the benefit package to meet the expectation of the customer. The products offered by a restaurant can be classified into five levels like core benefits, basic product, expected product, augmented product and potential product. Core benefit is the fundamental service or benefit that the customer is buying. Basic product indicates the basic functional attributes of the product that is offered by the service provider. Expected product is the attributes that are normally expected by the customers. Augmented produ ct indicates the facilities or services that are provided by going beyond the expectations of the customers. Potential product are those that are created by innovation and distinguishes the service provider from others operating in the market (Srinivasan, 2012). In case of the restaurant chain the core benefit will be the taste of the food and the Italian cuisine in which it specialises. Studies have shown that eating habit of the people of London has undergone dramatic changes due to the opening of restaurants of diverse tastes specially French, German, Italian, Australian etc (White, 2011). The basic product will be foods and drinks of diverse origin and taste. The expected products that the restaurant offers is cleanliness and good ambience that is perfect for family and official dining. Augmented services would include just in time services, aroma and music. The potential product that would make the restaurant most distinguishing is the Italian food and some dietary foods; since people of London are now getting more and more diet concerned and health conscious (Wheelock, 1997). Price Competitive pricing should be done in order to be acceptable to the customers. It is the general tendency of the customers to link the price with the product or services offered by the organization. In simple words it indicates that the pricing of any product or services is largely influenced by the quality perceived by the customer

Analytical Essay on Short Fiction Example | Topics and Well Written Essays - 1250 words

Analytical on Short Fiction - Essay Example Based on the specific levels various people behave in different ways towards themselves and others in relation to education. Therefore, education is shown to have both divisive and combining powers. In this sense, this paper will analyze this aspect in the â€Å"Everyday Use† book by Alice Walker. It will evaluate the different feelings brought about by education and the examples that are used to achieve this notion. â€Å"Everyday use† portrays education as an element that is so much sort after for its numerous benefits to the individual and the society. On the other hand, there is a contradicting element linked to this factor. The characters in the book are shown to look for education in order to make a better life out of their current slavery status. The main character who is portrayed to look for this is Dee. She is a slave who desires education to make her situation better. However, she faces a great challenge in her inability to go to the school that she wants. However, after a lot of sacrifice from her fellow slaves she attends school where she gets a lot of ideologies and knowledge. Therefore, she is enlightened in a way that she wants to find the truth. As a result, the positive elements expected from education are not fully achieved. Instead, a long formed friendship and family ties are broken and the individuals separated. The lofty ideas and educational opportunity that Dee fi nds give her a sense of loss of heritage. In turn, she seeks her background, and identity that can only be provided by her family (Walker, 1992). During the time period between the 1960s and the 1970s the African Americans did not get the chance to engage in as many activities as the other citizens were. For instance, the people from other races were given the opportunity to take part in various education activities. Education is principle reason why the knowledge, skills and values are accumulated and transmitted from one generation to another.

Corporate Fundraising Essay Example | Topics and Well Written Essays - 1750 words - 4

Corporate Fundraising - Essay Example It is worth mentioning in this context that corporate fundraising options available to a particular business depends on various factors including the size of the company which further signifies its certification as a public or a proprietary company as per the Corporations Act 2001 (Cth) (â€Å"A Practitioner’s Guide to Corporate Law†, 2007). To be noted, as per the Corporations Act 2001 (Cth) Section 45A, a proprietary company can be limited or unlimited with share capital. Another type of company identifies as per the Corporations Act 2001 (Cth) is the public company wherein the Section 195 of the Act specifies that â€Å"public company means a company other than a proprietary company† (â€Å"Corporations Act 2001† 2005). Also, the corporate name of a proprietary company is distinct to that of a public company, i.e. a limited proprietary company is denoted with the abbreviation â€Å"Pty. Ltd.† while an unlimited proprietary company is abbreviated as â€Å"Pty.† Contextually, the public limited companies are denoted as â€Å"Ltd.† at the end of the registered name of the entity (â€Å"Corporations Act 2001† 2005). With reference to this context, The Green Coffee Company Ltd can be identified as a public limited company which shall further determine its fundraising obligations when attempting to invest in an international expansion venture to Vietnam. One of the major differences and opportunities for The Green Coffee Company Ltd in fundraising, being a public limited company, is that it can issue equities or sell its debentures or shares to â€Å"more than 50 non-employee shareholders† through the obligatory issuing of prospectus where proprietary companies (either limited or unlimited) are exempted from such permits (â€Å"Corporate Law† 2011). From a managerial concern, fundraising activities performed by organizations such as The Green Coffee Company Ltd will quite essentially give rise to company liabilities and thus seize the risk of affecting shareholders’ or investors’ interests.  

Managing small business Essay Example | Topics and Well Written Essays - 3000 words - 2

Managing small business - Essay Example Mama Mancini’s is a small, family run business. It was started way back in 1913 when Arturo Mancini set up an Italian restaurant in downtown Chicago, serving genuine home made sauces. Over the years, the popularity of the restaurant’s Italian sauces encouraged Bruno, the third generation Mancini, to start up a separate business in the manufacture of sauces. Although this is a small family owned business, in the past five years the popularity of their sauces has spread and they have expanded their operations in the greater Chicago area, with their sales doubling over a five year period. Whereas the business was running at a loss five years ago, the break even point was reached during the third year. The company’s financial statement may be summarized as follows: The success of this small family owned business is largely due to good planning, the quality of their product and the identification of the niche market. To a great extent, the vision and planning of the owner Bruno Mancini has contributed to its success. This Paper focuses on the dynamics of owner-owned enterprises and the case of Mama Mancini’s was chosen because it is a typical example of a successful, family owned small business, which are cropping up in increasing numbers all over the world. What classifies Mama Mancini’s as a family owned business? A family owned business is classified as such when family members own and operate the operations of the business. While researchers have put forth many definitions of family owned small businesses, there is general agreement that family involvement in ownership and management classifies the enterprise as a family owned business (Handler, 1989).

Discuss the idea(s) developed by the author about the significance of our memory of the past - Essay Example Memories of the past especially regarding racialism and the white supremacy mentality are evident and still haunt Walt’s future. In other words, the belief that the white race was supreme than others, which was practiced and held for many years still haunts memories of the actor in his past. For example, the author indicates that though "Hmong might be good people," if they wanted anything fixed such as appliances or even cleaning up a yard or even ending the gang war that affect the society, they needed a white person to help and that the white may get away with anything thing. The racist mentality that was practiced in the past still haunts the author; he believes that the whites are supreme over other races in all aspects. The past beliefs in cultural superiority dictate his relationships with other races, which as the film illustrates prevents the author from establishing a cordial relationship with others. Understanding one another early enough dictate how people interact later in life and how this interaction impacts their lives. Walt’s memories of the good and meaningful life he had in the past as a soldier and with the family affects his life, considering he is now alone and in different settings. This makes Walt to sink deep into loneliness and reject any gesture that seeks to lift him from this life. For instance, his oldest son and his wife bring him a birthday gift to make his life better and cheer him up. However, his son’s motives are against Walt’s values and feelings. As a result, he rejects the gift and the suggestion of a retirement home. This suggests that everyone views life in a different and unique lens. In other words, there is a need to understand others and their needs to avoid conflicts. The fact that the two do not understand one another results into conflict. If the two had understood one another before, the son could have known what his fat her needed most at the time,

Environmental Impact of Prescribed burning in the United States Essay Example for Free

Environmental Impact of Prescribed burning in the United States Essay The term prescribed burning refers to a management practice in which fire is used to burn a predetermined area under specified environmental conditions.   Burning in this case is used as a management tool in areas that are vulnerable to catching fire due to the ground cover that acts as fuel load. In addition, burning is considered to be the most environmentally friendly and cheapest method of having woody growth in an ecosystem controlled.   Prescribed burning in the United States is common. In this form of burning, controlled fires are used to burn a specified land area after proper planning which ensures that the present weather conditions are favorable for the burning. When weather conditions are not suitable for the burn, negative impact of the fire in the burnt areas is likely to be witnessed (Dale et al, 2009).   In the United States, prescribed burning is considered to be a very important management tool due to the benefits associated with it.   Both the landowners and the United States National Forest System have been using prescribed burning for many years. According to the United States fire policy in relation to the forest ecosystem, there is need to undertake prescribed burning in order to enhance the growth of commercial forests, prevent wildfire damage and to enhance fire dependent ecosystems.   However, prescribed burning has been criticized for its negative impact on the environment. For instance, prescribed burning results to the clearing of land or use of land for agricultural activities that have negative effects on the environment.   In this paper, the impact of prescribed burning on the environment in the United States will be discussed.   The paper will focus on the effect of prescribed burning on land after it is cleared by prescribed fires.   Land clearing that results from the burning impacts negatively on the vegetation, soil, water and biodiversity. Thesis In the United States prescribed burning is made necessary by the conditions in the forest ecosystems or ranches. The burning aims at preventing wildfires that can damage properly or lead to death of the people if the fuel load on the ground encourages wild fires.   In addition, the United States national forest system undertakes prescribed burning activities due to the ecological benefits that burning gives to the forests.   The national forest system associates prescribed burning to the reduction of wildfire hazards, land improvement, game habitat enhancement, insect and disease management and site preparation for reforestation (Biswell, 1999). Examples of areas that have undergone prescribed burning activities include the California wild lands, Florida Flatwoods and the Southern eastern US National Forest.   It is important to realize that although prescribed burning in these areas has its benefits to the ecosystem and the people; it also impacts negatively on the environment over time. Negative environmental impact of prescribed burning occurs despite the fact that prescribed burning is planned in a manner that minimizes negative effects of burning on the environment.   This has made the issue of prescribed burning to become a subject of debate in the country .While some consider prescribed burning to reduce negative impact of wild fires on the environment, burning can also impact negatively on the environment.   Land clearing that result from the burning has negative effect on the environment. Discussion Negative impact of Prescribed burning on vegetation after clearing of land Prescribed burning results to the clearing of land in a predetermined area as the fire burns the fuel load.   The burning has both indirect and direct negative effects after land clearing by the fire.   Land clearing in turn has negative effects on the vegetation, water, soil and wildlife. The negative impact of prescribed burning in the United States has been witnessed in some areas because prescribed burning has become a very important activity in the country. Every year, hundreds of thousands of hectares are burned. Although various methods of burning are used burn the vegetation cover in the predetermined areas, fires destroy the existing vegetation by either injuring or killing the entire plant or parts of the plant.   This depends on the duration that the fire burns or the intensity of the fire.   Prescribed burning based on the slash reduction method results to the reduction of debris. This method is also used to reduce debris in case of a natural event or road construction.   When management ignited fire is used, the burning of a stand that has been established is done while ensuring that fire does not spread beyond the predetermined area. While small trees are completely burned during the burning, larger trees may survive the fires but some of their trees may be destroyed.   When fires are ignited, the burning forest fuels increase the temperatures which make it difficult for the vegetation to survive. Since when it comes to burning the temperature of the vegetation and that of the air are very important, people who have the responsibility to ignite fires should do it when the air and vegetation temperatures cannot encourage fires that can have adverse effects on the environment.   For instance, prescribed fires in the United States during winter top kill the hard woods while hardwood rootstocks are killed by summer burns. In areas where burning has not been done for a longtime, deep organic layer that accumulates during prescribed burning leads to the cambial damage of trees. Because only little heat is required to destroy the plant cells in growing plants, burning the vegetation kills growing plants. This leads to the short and long term destruction of the vegetation which over time exposes land to changes that impact negatively on the good conditions of the environment. One short term and long term impact of prescribed burning in the Sequoia and Kings Canyon National parks in the United States is the change in species composition (Mary Berth, 2000).   This change alters proper functioning of the ecosystem since it leads to the growth of new species while those that earlier existed and are not tolerant to fire before the fire fail to regenerate. These two parks are located in California’s South Nevada areas.   The parks cover about 864, 383 acres of land and prescribed burning in these two parks was made necessary by the desire to initiate ecological benefits in the parks.   The two parks prescribed fire programs were developed in 1969 and continues to be implemented in order to reduce fuel hazard problem that may result from heavy surface fuel loads.   Though the fires have been used to reduce the damage that may result from severe wild fires, change in species composition due to the clearing of land by fires has over the years been witnessed in the parks. Fires have limited the growth of species that are not tolerant to the fire ignited over a long time.   For instance, the increase in relative density of the giant Sequoia due to prescribed fires over a long time has altered the growth and survival of some other plant species.   The successful fire regimes restoration in the parks has encouraged the regeneration of the species that are fire-adapted at the expense of the species that are less-adapted to fire.   The reduction of fuel load and the restoration of forest structure after the fires alter the number and pattern of growth of plant species.   The parks have conifer forests dominated by the sequoia species. The change in the species number in a forest ecosystem affects the proper functioning of the natural ecosystem and this may lead to bare ground and soil erosion when plants and animals that promote proper functioning of the ecosystem are eliminated from the environment. In ecologically sensitive habitats in the United States, prescribed fires have had adverse effects on the regeneration and survival of plant species.   For example, the riparian areas in a forest system.   A study carried out to determine the effect of prescribed fire on the riparian areas in the Dark Canyon area showed that the fire consumed 90 per cent of the ground fuel, 79 per cent of the riparian zone pre-fire fuel, and 34 per cent of the total surface fuel.   The fire significantly reduced the percentage cover of the surface vegetation (Beche et al, 2005). As compared to the unburned areas, the burned area showed a change in the plant taxa richness after the regeneration of vegetation.   The reduction in plant taxa cover and richness changed the under story riparian vegetation community composition. These changes show that when an area experiences prescribed burning for a long time, disappearance of some species can lead to reduction in the percentage of vegetative cover. In the California Oak woodlands, the Native Americans used fire to have the Oak woodland vegetation altered.   Prescribed fires are considered to reduce the under story woody vegetation and have the tree density is lowered.   After the fires, regeneration may result to growth of vegetation in patches.   Since the settlement of Euro-Americans in the area, prescribed fire ignited in an ecosystem to create land for livestock ranches has removed the vegetation cover and instead encouraging the growth of plant species that are good for forage production. The woody vegetation in the area has been affected.Eventually, reduced vegetation cover has made it easy for soil to be exposed to either wind or rain erosion.Prescribed fires in Oregon’s Mixed – conifer forests of Crater Lake over the years have altered species composition by killing species that are not fire resistant while providing favorable conditions for the regeneration of fire-resistant species (Agee, 2003).   The Crater Lake National park has in the past prescribed a fire program that aims at increasing growth of pine trees and killing of the white fir tree species in the park.   Natural ecosystems can undergo succession to form forests that are dominated by the hardwood. The southeast region in the United States is considered to be the most fire dependent area in the country.   The removal of fuel loads in burned areas impacts negatively on the environment when over time plant species that support proper functioning of an ecosystem are eliminated. This makes an ecosystem to be vulnerable to changes that have adverse effects on the environment.

Penicillins Structure and Function

Penicillins Structure and Function Rachael Sim Hwee Ling A Molecule that Shapes the World – C16H18N2O4S The discovery of penicillin has revolutionized the world of medicine and saved millions of lives. Penicillin is a group of antibiotics derived from Penicillium fungi  [1]. Antibiotics are specific substances derived from living organisms that can inhibit the life processes of other organisms  [2]. Penicillin is effective against a range of bacteria such as staphylococciand streptococci and bacteria causing diseases like meningitis and gonorrhea  [3]. Unlike sulfanilamide which is toxic to the kidney, penicillin has no harsh effects. It is non-irritating and can be applied to tissues directly  [4]. During World War II, the administration of penicillin to the wounded soldiers greatly reduced their chanceS of injury infection and raised their survival chances in the interim time between the wounding and surgery (14 hours for the Allied Forces), thus dramatically reducing the need for amputations and the death toll from infected wounds  [5]. Today, penicillin is still commonly used to treat conditions. Penicillin is often prescribed after dental surgery to prevent infections  [6]. The diseases and infections mentioned above are caused by bacteria. Almost all bacteria have cell walls made up of peptidoglycan, a rigid but elastic structure, that protects the underlying protoplast from mechanical damage and prevent it from bursting under osmotic pressure. Peptidoglycan is made up of long polysaccharide chains that are cross-linked via flexible peptide bridges  [7]. The synthesis of bacterial cell wall is catalyzed by the enzyme transpeptidase. Such synthesis is essential to the growth, cellular reproduction and maintaining the structure of bacteria. In 1965, Tipper and Strominger hypothesized that penicillin kills bacteria by blocking the action of the transpeptidase that catalyzes the last step of synthesis which involves the cross-linking of different peptidoglycan chains, thus inhibiting the synthesis of the cell wall  [8]. Water then enters the cell causing it to swell and explode. This essay will discuss how penicillin’s shape, structure, instability enable it to inhibit the action of transpeptidase, examine the science behind penicillin’s reaction, how the structure and size influence its effectiveness and the significance of the lack of symmetry. Penicillin structure consists of a thiazolidine ring fused to a ÃŽ ²-lactum ring to which a variable R group is attached by a peptide bond. (Fig 1) Penicillin G (Fig 2), which has a benzyl side-chain, is often regarded as the prototype of the class as it is one of the first-generation penicillin that can be obtained directly from the fungi. It is the most potent of the class against susceptible gram-positive bacteria and is still widely used.[9] Penicillin G is only effective against gram-positive bacteria in which the transpeptidases are directly accessible. Fig 1: General Penicillin molecule with R side chain, 3 chiral centres (*) and a ÃŽ ²-lactum ring (blue) Fig 2: Natural penicillin-G where R = benzyl group Fig 3: D-Alanyl-D-alanine which closely resembles penicillin (In D-amino acid, with the H atom pointing up and looking down from the H atom and moving anti-CW, the amino acid has the order COOH, R, NH2) One explanation about the mechanism of action of penicillin is that it mimics the shape and structure of the D-alanine-D-alanine termini of bacterial peptidoglycan (the usual substrate) and is thus recognized by transpeptidases  [10]. The transpeptidase enzyme reacts preferentially and binds irreversibly with penicillin. The penicilloyl-enzyme formed is stable and does not react any further  [11]. The free COOH group present mimics that of terminal carboxyl of D-alanine-D-alanine and is needed for penicillin to bind at the active site  [12]. The similarities in their molecular structures can be clearly observed in Fig1 and Fig3. Furthermore, as penicillin lacks symmetry, its mirror images are non-super-imposable. In order for penicillin to be biologically active, the 3 chiral centres in penicillin must be in the configuration in Fig1  [13]. As penicillin’s activity is stereo-dependent, penicillin synthesized must be enantiopure and the arrangement of the groups relativ e to one another should resemble that of D-alanine-D-alanine. This also explains penicillin non-toxicity. D-alanine only occurs in the cell wall of bacteria and all the proteins within our body are built up from L-amino acids. Hence, penicillin kills bacteria but will not adversely affect humans.  [14] Another explanation also relates to the structure of penicillin and the instability of the cyclic amide in ÃŽ ²-lactum ring which is fused to the thiazolidine ring. Research by Strominger has shown that the activity of penicillin is due to the inherent strain of the four-membered ring or to the reduced amide resonance  [15]. In the four-membered ring, the C and N atoms are forced to have a bond angle of approximately 90 ° which is far below the preferred bond angle for singly-bonded sp3 hybridised carbon and nitrogen atoms (109.5 °) and doubly-bonded sp2 hybridised carbon atom (120 °). This put the small ring under great ring strain which is further aggravated by the five-membered thiazolidine ring fused with it. X-ray crystallography has also showed that the two fused rings and the amide bond is non-planar. This leads to a loss of resonance stabilization normally found in these amide bonds  [16]. These make the amide group more reactive. Penicillin acylates the enzyme and form an open chain compound to relieve the strain. Furthermore, it is hypothesized that the –COOH group in penicillin’s structure contributes to penicillin’s widely varying acylating ability and its ability to travel through bodily fluids unaltered and only target transpeptidase in bacteria. Experimental data obtained from inelastic neutrons and quantum chemical theory suggests that the activity of penicillin is pH dependent  [17]. Under physiological conditions (pH = 7.4), penicillin’s -COOH group is deprotonated. As COO and the lone pair of electrons of N are on the same face of the molecule, the COO will repel the lone pair of electrons on the N atom. This shortens the amide bond, increases its strength and decrease the acylating power of the lactam ring  [18]. When near the active site of transpeptidase, COO group is protonated and the ÃŽ ²-lactum amide bond regains its strong acylating power  [19]. The 2 CH3 group is also important for activation as research has found no activity for penicillin analogues with these groups removed.  [20] At the active site, the science of reaction is as follows. The nucleophilic –OH group of the serine residue attacks and opens the ring. A covalent bond is formed between the serine on the enzyme and the penicillin molecule  [21], irreversibly inhibiting the normal function of the enzyme and kills the bacterial cell. The R group in the penicillin structure determines the effectiveness of the penicillin drug. Penicillin-G cannot be consumed orally as gastric acid will catalyze the hydrolysis of the highly unstable ÃŽ ²-lactum ring, destroying its antibiotic properties. The ÃŽ ²-lactum ring is also susceptible to attack by O atom of the neighboring carbonyl group. To prevent this, we can choose an electron withdrawing R group to decrease the nucleophilicity of the carbonyl oxygen on the acyl side chain to reduce the self destructive mechanism[22]. To avoid degradation by penicillinase enzyme, we can choose a bulky R group as a steric shield. The small size of penicillin molecules increases their potency as it enables them to penetrate the entire depth of the cell wall. In conclusion, penicillin-G is a molecule that was cleverly designed molecule by nature. All features in its structure – its bicyclic system, unstable ÃŽ ²-lactum ring, COOH group, stereochemistry and size is essential and influence its effectiveness. They enable penicillin to irreversibly react with transpeptidases, kill harmful bacteria and by doing so, save lives and shape the world. [1] penicillin.

The Effect Of Tourism On Peoples Lifestyle Tourism Essay

The Effect Of Tourism On Peoples Lifestyle Tourism Essay According, Gawler believed that tourism is effecting to economic and lifestyle of people in each area of tourism. Tourism has fears that is expanded to tourism and related to badly react or mass tourists. Anyway, tourism can be both positive and negative impacts on countries. Moreover, Mirbabayev and Shagazatova said that nowadays, tourism is the largest factor of economic. Tourism is evolving in economic activities. Various sectors of economy have affected from growing development rates; infrastructure development, foreign currency inflows, and new management. They can be contributed to the social and economic development in big part of the country. Also, Lehmann (2005) explained that there are three distinct parts: direct, indirect, and induced in the total economic impact of travelers First, the direct impact is the value added of those sectors that interact directly with the visitor. Second, the indirect impact is the benefit to suppliers to those direct sectors. Third, the induced impact adds the impact of tourism-generated wages as they are spent in economy. In addition, Rattanasuwongchai (1994) told that Tourism is the fastest growing industries and can generate national income in developing economies. Same as the other, Thailand has a tourism that is a major source of national income. Although tourism had some negative effects, it has covered all level. Otherwise, Sugiyarto, Blake, and Sinclair (2002) defined that tourism took place within a large context of the world economy. Besides, Sherpa (2006) said that tourism is a major economic activity providing livelihoods to poor people. Moreover, Bartsch (1998) said that Tourism conducted tourists visiting the village. They can get extra income and took advantage by offering accommodation to tourists. Likewise, Khadka (1996) explained that International tourism is a fast growing in economic factors. It increased in national income. Meanwhile, Albqami (1997) said that Tourism had received more attention in nowadays. Tourism stimulated to the economic growth. Similarly, Suntikul (2008) told that Tourism has a difficult problem. Tourism is accepting as the economic and societal importance of tourism activity. However, tourism has poorly managed within its economy, social, and environmental contexts. The meaning of the impacts of tourism cannot be properly assessed. Advantage of tourism impact According, Gawler (2001) believed that the advantages of tourism are economic development. Tourism is helping to support communities, particularly in rural areas. There are little dependences on urban centers and imports to sustain tourism activity as we called decentralised. Tourism development often brings a range of benefits to host communities. Improved infrastructure power, water, and telecommunications, services (banks, transport) and new investments, all serve to enhance the lifestyles of communities. Tourism can make a sense of community pride in their location. Tourism can exchange for cultural between communities and visitors. Tourism creates regional identity both nationally and internationally. Conservation area efforts and provides effective management of significant areas can get the fund for conservative and management. Tourism can promote the preservation. Otherwise, Mirbabayev and Shagazatova supported that Tourism can be both a source of international peace and understanding. Here are possible positive effects of tourism: Tourism is developing positive attitudes towards each other culture and learning about each others culture and customs. Also, Tourism is reducing negative perceptions and stereotypes. Tourism is developing friendships and developing pride, appreciation, understanding, respect, and tolerance for each others culture. Finally, Tourism is increasing self-esteem of hosts and tourists. Similarly, Lehmann (2005) said that tourism consists of share of the retail, transportation, restaurant, lodging, and entertainment industries directly contribute to the travel sector. Tourism directly gave nearly $1.64 billion in Palm Beach County on 2004. Meanwhile, Sugiyarto, Blake, and Sinclair (2002) defined that the levels of GDP and employment are increased by tourism growth. Trade, tax and balance of payment can increase by tourism activity. Additional, Albqami (1997) said that tourism industry is increased; the industry will need to purchase more input in the economy to produce the additional output. These purchases will stimulate additional output. Disadvantage of tourism impact According to, Rattanasuwongchai (1994) told that a huge number of tourists exploit natural resources. Tourism has a heavy impact on the environment. In addition, tourism needs more infrastructures, transportation and other facilities which can cause environmental suffering. Tourism caused environmental pollution from human waste, sewerage into water sources, and trash. Without strict regulations in land using, most hotel may invade the preservative areas. It can be cause of declining in participation in rural traditional. Similarly, Bartsch (1998) explained that Tourism in Ban Chaidee is does not replace any other activity, and agriculture which is still regarded by people as most important economic activity. Environmental damage and government policies have decreased the traditional resources of the villagers. The pollution caused by tourists, noise pollution late at night. Moreover, Khadka (1996) explained that Environmental and socio-cultural depletes may make tourism unsustainable. These factors can also be regional in their nature or impact. Otherwise, Sherpa (2006) said that tourists had a negative effect to loss of rural culture. In additional, Suntikul (2008) told that tourists took a critical the cultural in tourism practice, and the host culture. Tourism is introducing negative impacts to Luang Prabang.

Electricity has three features that include current, voltage and resistance. Current is the flow of electrons round a circuit that is measured by the ammeter in amps (A). Whilst the voltage, refer to as potential difference, is the driving force that circulates the current around the circuit that acts like an electrical pressure. The unit of measurement for this is Volts (V), which is measured by a voltmeter. Resistance is a force that slows down the current; consequently it slows down the flow of current. This is measured in Ohms (W). Between the voltage and resistance there is equilibrium, where the voltage impels the current, whereas the resistance is opposing this electrical pressure. The relative sizes of the voltage and resistance decide how big the current will be. Increasing the voltage allows more current to flow, whilst increasing the resistance would decrease the amount of current flowing round the circuit. Discovered by George Ohm in 1826, the current is in direct relative amounts to the potential difference. If the temperature is kept constant as well as other conditions, Ohms law is obeyed. The graph on the side illustrates the current through a resistor is proportional to the voltage. V=IR gives the formula for Ohms law. In order for current to flow it requires electrons to carry the electric current. The electrons are the negative charge that can freely move about. Within metals there are a sea of electrons that can carry the electric current, which is reason why they conduct so well and are used for many purposes, such as wires. Factors During the investigation there will be many factors that will affect the resistance in a wire. These factors include:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Length of wire – If the wire length increases, the distance for the electrons to pass through would take a longer period of time since the electrons collide more with atoms of the wire. As a result there is an increase in resistance as the number of collisions cause the electrons to flow slowly, which justifies the term for resistance. Conversely if the length of the wire is shortened, the time taken for electrons to travel is reduced given that there are not as many electrons colliding with atoms. As results there are a small number of collisions, hence reduces the resistance.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Thickness of wire - A wider breadth of the wire causes atoms within the wire to expand a small distance between each other.

William Shakespeares Hamlet Essay -- Shakespeare Hamlet Essays

William Shakespeare's Hamlet Hamlet is a play about intrigue, suspicion, treachery, and revenge. Its characters, the vast majority of whom are experienced members of the court, move through this world with varying degrees of ease, but all are accustomed to the forces at work. Hamlet’s reluctance to act out the revenge he knows is his duty does help the modern-day audience relate to him, perhaps, but at the end of the day he is still a part of this foreign culture, driven by customs and expectations very different from those that govern the life of his audience. There is one character in the play, though, who seems just as bewildered by the startling events swirling around her as the audience is. Ophelia’s main importance in the play is to act as a sort of emotional representative for the audience. We first meet Ophelia in Act I, scene iii, as preparations are being made for her brother’s departure. Laertes brings up Ophelia’s relationship with Hamlet and cautions her not to take the prince’s advances at face value. Laertes explains that as Prince of Denmark, Hamlet is not entirely free to declare his love for anyone without considering the potential effect on the country. Their father takes up the lecture later in the scene, citing Hamlet’s youth and gender as reasons why he should not be trusted. Poor Ophelia is rather dismayed at this, and even goes so far as to protest that â€Å"He hath importun’d me with love in honorable fashion.† (I.iii.99-100) Both of these warnings come as something of a surprise to Ophelia and to the audience, and for the first time Ophelia has fulfilled her role as unwitting expositor. Through her own ignorance and naivete, Ophelia has allowed other characters to explain things to the a... ...derstanding. Ophelia feels her way through the play, and the audience is quite capable of doing the same. This emotion-based view of the action is a deeper connection to the characters than one would obtain by trying to keep track of Hamlet’s brooding and ranting or Claudius and Polonius’s reasoned plans. Ophelia gives the play its emotional payoff, and by the time she exits the play, the audience is already emotionally attached on her behalf. That’s not to say that sympathy for Ophelia makes the audience side with Laertes—after all, Ophelia loved Hamlet, even if he did lead to her insanity. Rather, Ophelia manages to ensure that the audience has connected emotionally to the play in a way that no other character does, so that when we lose Ophelia enough of a relationship to the play has been established that the audience can’t help but care about the outcome.

Junior High School Essay

It was during my 7th grade year that I decided upon my answer to the age-old question: â€Å"What do you want to be when you grow up? † Being that it was my first year at a junior high school, I was a little intimidated. I wasn’t fond of making new friends, so I stuck with the people I already knew from the year before. Jonathan, one of my closer friends, was as introverted as I was. He wasn’t looking for a whole lot of attention, but he did want to involve himself in school. Jonathan asked me to join the school’s drama club with him, so he wouldn’t have to do it alone. I decided to humor him and attend the first meeting one day before school. When I walked in the doors, I saw kids laughing and joking around. It was such a comfortable atmosphere; I barely even felt as if I was still at school. Drama club wasn’t just some club, it was a place for me to be comfortable with myself. It was an escape from the humdrum school days which seemed to get longer as time passed. The drama club was filled with people who weren’t afraid to make fools of themselves and wouldn’t judge me when I did the same. I could let myself be silly and not feel ashamed. I played games like ‘Understudy’ where a skit is started with a few students, the leader interrupts, and the students are replaced with new ones. The new actors then carry on the same general plot of the skit. It was the most fun I had experienced in such a long time. I caught myself going every Tuesday and Friday morning before school. We even planned to do a play one day after lunch. For once I was hoping to get some attention. I wanted to be seen. I had never wanted something like that before. I always laid low and kept to myself, but now I was on stage reading lines. The funny thing about all of this was that I wanted to do it. It was my decision, and I was happy with it. I enjoyed myself so much that I wanted to experience it more often, but with no theater in town, it was easier for me to watch movies. I watched more and more, and before I knew it, I started paying more attention to the actors instead of the storyline. I would watch a couple of movies that all featured one actor to see how his or her style would change. One in particular changed my amateur views of acting altogether, Primal Fear featuring Edward Norton who portrayed an older teen with multi personality disorder. His ability to make 180 ° turns in a single scene fascinated me. I could compare this to Sally Field’s role in the movie Sybil. I tried to find more movies with Edward that were as mind-blowing as the last. I watched Fight Club and noted that he again played a character with a split personality. Leaves of Grass was next on the list. Edward acted as his own twin brother, one who was a college professor while the other was a drug dealer. It seemed to me that his strategy was to unveil the pencil-thin line dividing good and evil or moral/immoral. It was amazing to me that I could learn so much about one person by watching him or her portray others. I fell in love with this theory, so I decided to try my hand at them by joining the Teche Theater of Performing Arts. I auditioned for a play named Gypsy based on the life of Gypsy Rose Lee. The role I was given was not very substantial, but it was a role nonetheless. Rehearsals lasted all summer, and I dedicated myself. I showed up early, and I stayed late. I sang and danced after I told myself I would never do that on stage. I realized my motivation was in the applause. I was looking for a thrill, and I found it in the crowd. I found it in making people laugh. I found it in making friends. Now THAT was different. Now, I was different. I was happy. I used this motivation to better myself. I did more shows at the theater, and I met new people. One of which was Mrs. Diane Wiltz, the main director at the Teche Theater. She would tell me how impressed she was by my versatility on stage, but she wasn’t ever afraid to point out when I was doing something wrong. She taught me to improvise when appropriate, push my character onto the audience, be loud, and overact. â€Å"Don’t hold back,† she would say, â€Å"when you think it’s too much, it is just right. † She also taught me to act comfortable in situations that might not be comfortable. Her advice was not bound to theater. I found that I could incorporate the lessons she taught me into everyday life. I took heed to the advice that she gave me. I did a few experiments to see how I could use these lessons offstage. I started pushing myself to be more extroverted at school by talking to more people, even the teachers. I became comfortable joking with complete strangers. I noticed that my overall attitude towards life changed somewhere along the way. I wanted to make people feel good. It felt good hearing laughter or applause, so I looked for it everywhere I went. I further involved myself in school and the theater. I took on roles in several more productions at Teche, becoming a regular there. The Teche Theater was like a second home to me by then, and I wanted so badly to do this for the rest of my life. I then decided to make plans to act professionally. I looked into finding a school that would help me get a foot into an acting career. I stumbled upon a film organization associated with the University of New Orleans. How could I make my way into an organization that I knew nothing about? It would be way over my head considering I knew little to nothing about film, and I wasn’t a student of UNO. I needed to get a little experience at another college before jumping into being a full-time student in New Orleans, so I decided to enroll at Nicholls State University. As of now, I plan on finishing my freshman year at Nicholls before transferring to the University of New Orleans. When I enroll at UNO, I will major in film arts and production. I will work with fellow students on projects as well as doing a few projects of my own. I will also work to serve as an intern on any major motion picture sets that is offered. Students at the University of New Orleans have helped work on the set of movies like Ray, Runaway Jury, and The Curious Case of Benjamin Button. These opportunities will hopefully open more doors for me, helping me start a career in this field. I look forward to seeing how I fare in a career that is so difficult to jumpstart, and I can’t help but to think of the people that inspired me and pushed me to be on the path that I am on today.

The Lion, the Witch and the Wardrobe

C. S Lewis wrote the novel The Lion, the Witch and the Wardrobe initially for his Goddaughter in order to keep her in touch with Christianity. What Lewis did not realize is that many adults would also enjoy the fantasy children’s novel as well. The narrative is filled with mythical creatures, humorous moments, and suspenseful situations. Although many events and characters seem improbable, the four children in the book—Peter, Susan, Edmund, and Lucy—are realistically portrayed as well-rounded characters with individual strengths and faults. Although the novel is recognized as a children’s fantasy book, it is also popular with adults as the story contains bits of modern culture, vivid descriptions of violence and is heavy on Christian allegory. As much as the readers enjoy the magical land of Narnia, 21st century life is not exactly full of Dryads, Naiads and Fauns frolicking and feasting in the summer woods. By contrast, in today’s children’s fantasy novels, not every injustice is punished, and not all the good people live happily ever after: some of them die, because that is reality. Between school shootings, gang violence and child abuse is seems as though reality is thousands of miles away from the fantasy of complete and total justice in Narnia. What readers of all ages can relate to, however, is betrayal. For example, spouses who cheat, employees who steal from their employers, and friends who tell lies. This modern idea of betrayal is where readers from any age can relate to the novel. In the narrative, Edmund’s first betrayal is a small but unpleasant one: â€Å"Up to that moment Edmund had been feeling sick, and sulky, and annoyed with Lucy for being right, but he hadn't made up his mind what to do. When Peter suddenly asked him the question he decided all at once to do the meanest and most spiteful thing he could think of. He decided to let Lucy down† (Lewis 48). Edmund lies about his trip to Narnia in order to make himself look superior in the eyes of his older siblings. This small cruelty will pave the way for his greater betrayal further in the story. Readers of any age can connect with the modern culture of betrayal in the novel, where minimal details are explored that over time lead to Edmund turning his back on his siblings. This novel features an odd mix of childish adventure and bloody battles. Young children who read this story enjoy the fairy-tale aspects, while older readers can appreciate the repetition of scenes in which the children are often comforted by the sudden availability of tea, and the way the forces of good seem to always outweigh the evil. The use of violence throughout the novel deals strictly with fantasy for children, where it is mainly used for excitement. On the other hand, for older readers the violence in the novel can be seen as consequential where extreme force is used as simply last resort. For example, as the head of the forces of evil, the White Witch is not playing a long hand when she exclaims, â€Å"Summon all our people to meet me here as speedily as they can. Call out the giants and the werewolves and the spirits of those trees who are on our side. Call the Ghouls, and the Boggles, the Ogres and the Minotaurs. Call the Cruels, the Hags, the Spectres, and the people of the Toadstools. We will fight† (Lewis 149) There are many different creatures in Narnia that follow the White Witch and she merely acts as their stone cold captain. This quote explores evil where it is not an isolated incident in Narnia – it is the idea of violence and commands a great deal of power. The Lion, the Witch and the Wardrobe functions as a spiritual allegory where one does not have to be too familiar with the Bible to recognize some of the key characters and themes. Without doubt, Aslan represents Jesus Christ, and also God himself, whereas the White Witch represents Satan. Narnia, where the adventure happens, visibly represents the Kingdom of God. Clearly there is no direct retelling of any of the Bible stories; however, readers can find elements taken and redistributed for younger readers. In addition, having this biblical reality come to life is important to ensure a committed Christian lifestyle not only for children, but also for adults. For instance, when Edmund arrives in Narnia alone, he immediately meets the White Witch where he is tempted with the enchanted Turkish Delight and the promise of becoming a prince of Narnia. The White Witch explains to Edmund, â€Å"I think I would like to make you the Prince – some day, when you bring the others to visit me† (Lewis 40). Succumbing to temptation is a very powerful theme in the Bible, where Jesus is tempted by Satan in the wilderness with promises of great power. Not only does Lewis restate certain events in the life of Jesus in a context that is easy to understand, most importantly, readers of all ages can both relate to and enjoy the fantasy of Narnia. An understanding of the modern reality, use of violence and Biblical allegory in the novel is essential in satisfying both younger and older readers. The Lion, the Witch and the Wardrobe has already established itself as a timeless novel that appeals to both the atheists and Christians, the uneducated and to scholars, and lastly to children and adults. In addition to being a children’s fantasy book, it is an adventure story in which the heroes set out on a quest to recover their kidnapped friend and end up ruling the land. An analysis of this narrative, however, allows readers of any age to fully appreciate Lewis’ unique gift to simplify complex ideas and craft beautiful children’s fantasies. Thus, this allows the reader of any age group to gain a deeper understanding of Lewis as a skilled creative writer and a deeper satisfaction of his artwork, The Lion, the Witch and the Wardrobe.

Disadvantages of video games Essay

Video games have been available to consumers for the last 30 years. They are a unique form of entertainment, because they encourage players to become a part of the game’s script. Today’s sophisticated video games require players to pay constant attention to the game, rather than passively watching a movie. This has both positive and negative impacts on players. Several studies have been published that explore these impacts on today’s children. Sections: What impact does playing video games have on children or adolescents? Tips on managing your child’s media consumption. The Entertainment Software Rating Board (ESRB) References What impact does playing video games have on children or adolescents? The most widely used â€Å"positive† impact video games are said to have on children is that they may improve a player’s manual dexterity and computer literacy. Ever-improving technology also provides players with better graphics that give a more â€Å"realistic† virtual playing experience. This quality makes the video game industry a powerful force in many adolescent lives. However, numerous studies show that video games, especially ones with violent content, make teens more aggressive. Part of the increase in aggressive behavior is linked to the amount of time children are allowed to play video games. In one study by Walsh (2000), a majority of teens admitted that their parents do not impose a time limit on the number of hours they are allowed to play video games. The study also showed that most parents are unaware of the content or the Entertainment Software Rating Board (ESRB) rating (see below) of the video games their children play. In another study conducted by Gentile, Lynch, Linder & Walsh (2004, p.6) â€Å"adolescent girls played video games for an average of 5 hours a week, whereas boys averaged 13 hours a week†. The authors also stated that teens who play violent video games for extended periods of time: Tend to be more aggressive Are more prone to confrontation with their teachers May engage in fights with their peers See a decline in school achievements. (Gentile et al, 2004). The interactive quality of video games differs from passively viewing television or movies because it allows players to become active participants in the game’s script. Players benefit from engaging in acts of violence and are then able to move to the game’s next level. Gentile & Anderson (2003) state that playing video games may increase aggressive behavior because violent acts are continually repeated throughout the video game. This method of repetition has long been considered an effective teaching method in reinforcing learning patterns. Video games also encourage players to identify with and role play their favorite characters. This is referred to as a â€Å"first-person† video game (Anderson & Dill, 2000, p. 788) because players are able to make decisions affecting the actions of the character they are imitating. After a limited amount of time playing a violent video game, a player can â€Å"automatically prime aggressive thoughts† (Bushman & Anderson, 2002, p. 1680). The researchers concluded that players who had prior experience playing violent video games responded with an increased level of aggression when they encountered confrontation (Bushman & Anderson, 2002). In a Joint Statement (2000) before the Congressional Public Health Summit, a number of American medical associations — the American Medical Association, American Academy of Pediatrics, American Psychological Association, American Academy of Family Physicians and American Academy of Child & Adolescent Psychiatry — caution parents about violence in the media and its negative effect on children. Their report states that exposure to violent media can elevate aggressive feelings and thoughts, especially in children. These effects on aggressive behavior can be long-term. Although fewer studies have been conducted on interactive video games, evidence suggests that playing violent video games may have a more dramatic influence on the behavior of children and adolescents (Joint Statement, 2000). Back to top Tips on managing your child’s media consumption Because of the popularity of video games, completely eliminating them from your child’s life might be difficult. But you can decrease the negative impact that they have on your child. Here are a few tips: Know the rating of the video games your child plays (see below). Do not install video game equipment in your child’s bedroom. Set limits on how often and how long your child is allowed to play video games. Monitor all of your child’s media consumption — video games, television, movies and Internet. Supervise your child’s Internet use — there are now many â€Å"video games† available for playing online. Take the time to discuss with your children the games they are playing or other media they are watching. Ask your children how they feel about what they observe in these video games, television programs or movies. This is an opportunity to share your feelings and grow closer with your child. Share with other parents information about certain games or ideas for helping each other in parenting. Back to top The Entertainment Software Rating Board (ESRB) The ESRB is a self-regulatory body established in 1994 by the Interactive Digital Software Association (IDSA). The major video game manufacturers created this board after concerned groups applied pressure over the content of video games. Similar to the movie industry’s rating system, all major game companies now submit their new products for rating to specially trained raters at the ESRB. The ESRB rates over 1,000 games per year. The ESRB looks at a number of factors when rating games. In particular, it considers the amount of violence, sex, controversial language and substance abuse found in a game. Based on its developed guidelines, the ESRB then gives an age recommendation and content descriptor to each game submitted. The following are the rating symbols currently in use, according to the ESRB Web site. Early Childhood (EC): Content should be suitable for children 3 years and older and contain no objectionable material. Everyone (E): Content suitable for persons ages 6 and older. The game may contain minimal violence and some â€Å"comic mischief. † Teen (T): Content suitable for persons ages 13 and older. Content is more violent than (E) rating and contains mild or strong language, and/or suggestive themes. Mature (M): Content suitable for persons ages 17 and older. Content definitely has more mature sexual themes, intense violence and stronger language. Adults Only (AO): Content suitable only for adults and may contain graphic sex and/or violence. Adult Only products are not intended for persons under the age of 18. Rating Pending (RP): Game has been submitted to the ESRB and is awaiting a final rating. The ESRB Web site has more details about this rating system, as well as the â€Å"content descriptors† that are used in conjunction with the ratings on game packaging. The site is also useful for parents who want to search for the rating of a particular game. Back to top References Bushman, B. & Anderson, C. (2002).

Divergent Minds

Divergent character or Divergent personality Thesis Statement on Personality vs Character: Even though society may have an impact to change our character, our decision is the ultimate factor that changes as we accommodate in the environment we live in. While parents have a major influence in our life at young age, what they instill is what has been created by their parents and their surrounding. We grow up with certain types of personalities from our parents but our characters are challenged or molded within our lifetime and who we are behind closed doors have made us to be divergent with society.The book â€Å"Divergent† by Veronica Roth shows how society can have an impact on ones personality but a persons character may never change. While parents have a major influence in our life at young age, Should our characters be challenged or molded by our surrounding? because I believe that personality traits and character traits are misunderstood. while personality is the first thi ng we see in a person such like a mask that someone would wear, we downsize the fact that a persons character is really who they are under pressure or alone in there room from the unseen eye of society.Personality perceives personality but who we are is rooted in our hidden character which are uniquely shaped by the surroundings in life, society, and culture we live in and Ironically, research has shown that personality traits are determined largely by heredity and are mostly immutable. Character traits, as opposed to personality traits, are based on beliefs (e. g, that honesty and treating others well is important—or not), and though beliefs can be changed, it's far harder than most realize.

Rhetorical Analysis Essay Example | Topics and Well Written Essays - 250 words - 5

Rhetorical Analysis - Essay Example Swift launches attack on the irresponsibility of the Ireland‘s lawmakers, the presence of the well-being in the society, dictatorship of the Englishmen and the desperation in which he sees the Irish people living in. He also puts across the Irish peoples reluctance and inability to stand on themselves. The work shows that the state, English and the Irish people are responsible for the misery state of the country. Political failure was all over the nation during the Swift time hence leading to several works written to criticize the political leadership. Their objectives were to pressurize them to provide solutions to economic problems, poverty and misuse of the poors children for the gain of the rich. The author protests bitterly on the inability of political leadership and attacks the introduction of several reformers towards economic changes. In conclusion, the main challenge to Swifts work is to get the public attention whose indifference was well focused. He puts his point negatively, to bring out the themes of morality, political incapacity and poverty which should be

Comparative Study of State and Local Governments Research Paper

Comparative Study of State and Local Governments - Research Paper Example Government of California The Californian government differs from other governments in a number of ways - from the laws to how it offers its services to its residents. It possesses one of the longest constitutions in the history of the world, caused by construed individual provisional rights that have been made broader than any other bill of rights. These rights help protect individual against oppression and illegal practices in relation to securing their life and rights of living. The law extrapolates on how every citizen is dealt with in any case of any happening or occurrence. The difference is also triggered by execution of three branches of governance which are: the executive, the legislative and the judicial branch. The California government differs from other states and governments in that it has an institution, even though not stipulated in the constitution but plays a major role in implementing laws. The institution comprises of the governor, assembly speaker, assembly minori ty leader, president of the senate and senate minority leader. The big five meet in private closed meetings to discuss pending bills in the formal legislature since it is an informal institution. California’s direct democracy system is approached with high aggressiveness contrary to all other states. It gives the population free will of giving their unprecedented opinions collectively in choosing good governance rather than electing representatives. Its gives the people pure and preferred choice in passing executive motions, conducting trials, making laws, election of officials and dismissing errant officials. The Californian system of direct democracy has positive effects on the government, in that it protects grievances of the people majorly done by them. This type of government gives audience to all its residents and deals with each of their problems. Contrary, a representative government will only shed light to problems that affect particular areas especially when they ac crue vested interest. Such a government ensures that services are consumer friendly so as to reduce uproars from the population. When such a population decides to take on the streets for a demonstration, the whole economy is left at a stand still. The governor in California State has accrued extensive powers in running the state. He or she heads the executive branch, which includes lieutenant governor, attorney general, state secretary, state treasure and state controller. The governor has powers and responsibilities to sign laws passed by legislature, appoint judges, command state militia, propose state budget and grant pardons among others. These aspects grant the governor more powers than the legislature since he approves all the decisions and without his consent, they are doomed for failure. Provision of funds to state and local governments have given a boost to direct democracy in that the channels of communications are dropped to reach people at grass root levels. This idea at tributes many people in bringing out their opinions on possible castigations they are experiencing and end up with a rapport with the government. Similarly, local governments and states reduce the distance covered by people when they require services from the government. Funs provided are used to construct offices and support

Individual Business Report - Zumo Smoothie bar international Research Paper

Individual Business Report - Zumo Smoothie bar international - Research Paper Example It is on this postulation that Zummo Smoothie Bar will be founded upon. Zummo Smoothie Bar will seek to serve the underserved market of smoothie lovers who don’t have too much cash to spare. It will also seek to provide better services by allowing the customers to choose their own menus as well as offer delivery services. By giving these value-adding services to the business of smoothie, it will be easier for Zummo Smoothie Bar to create a market segment for its products and survives and overcome competition from the already existing and established competitors such as Starbucks. Introduction The Smoothie market is a big market, in terms of the various market drivers such as number of potential customers (Cross, 58). Smoothies come in all forms, qualities, and amounts. In the Camden town, London, the smoothie business is a big business as indicated by the numerous smoothie bars which offer numerous services. There is however a market segment that seems to be underserved. This market segment includes those who would want to have a smoothie without having to dig too dip into their pockets. Most smoothie bars in Camden offer very expensive products which many people may not afford. In this regard, there is an opportunity to offer the products to this market segment. This market segment is composed of the people who are willing to compromise a little in the quality of the smoothie as long as they ca get on a better price (Lerner & Roberto, 90). Competitors The main competitor in the smoothie sub sector is Starbucks which offers high quality smoothies in the Camden area within London. Starbucks is an international brand which offers different types of beverages including smoothies. Apart from Starbucks, there are also a number of other competitors such as Chaboba Bubble Tea, White Kitchen, Shake My Shake and The Espresso Bar. These businesses offer smoothies as well as other beverages such as coffee and tea. Most of them are high-end smoothie bars and offer v ery expensive products. As a result, although these competitors will be offering the same products as Zummo Smoothie bar, they will not offer direct competition to Zummo due to the fact that Zummo Smoothie bar will be looking for a subsection of the market which the rest of the bars don’t attend to. Marketing strategy for Zummo of the Smoothie bar According to Weinstein (45), market segmentation is a very important market strategy. Zummo Smoothie bar will target a market segment which is composed of the younger people in the market which will include students. This segment of the market is composed of the people who may not have enough money to send too such on a product like a smoothie. In this regard, the Zummo Smoothie Bar will offer smoothies of average quality in order to make sure that its costs are within the profit threshold. This will help the Zummo Smoothie bar to be able to offer the product at a much lower price and therefore be able to meet the needs of the marke t. Discounts As Donnelly (85) says, offering discounts is a major way to engage the customers. Zummo Smoothie bar will make use of discounts as a way to attract and maintain its customers. Since the Zummo Smoothie bar will be targeting the students, they will be given discounts for buying from the shops. Quantity discounts will be offered to the customers for being regular customers. To achieve this, the customers will be issued with a

DNA Fingerprinting Research Paper Example | Topics and Well Written Essays - 1250 words

DNA Fingerprinting - Research Paper Example The high rate of variation results because DNA fingerprinting relies on non-coding hyper-variable sequences to produce a unique pattern of bands for each individual. DNA profiling relies on the discovery of a broad range of restriction enzymes and their specificity. DNA typing has a wide range of applications from paternity testing, criminal investigations, and population studies to identification of tragedy victims. Other applications are in conservation biology and evolution studies. However, DNA typing presents its challenges especially concerning the amount of sample and accuracy of the process. Introduction DNA fingerprinting has caused a revolution in the world since its description in 1985. Deoxyribonucleic acid is present in all body cells. DNA consists of a sugar, four nucleotides, and a phosphate group. The nucleotides commonly called bases differ in the frequency of occurrence and the order in which they occur. The general DNA structure is similar in all individuals. Howev er, the order and frequency of bases brings a remarkable difference between individuals. DNA fingerprinting presents a profile of an individual’s DNA. The four bases namely adenine, cytosine, thymine, and guanine form unique sequences on the two DNA chromosomes. Studies reveal that there are sequences that encode for essential proteins that are necessary for all cell functions. Geneticists called these coding sequences exons. In addition, there are non-coding sequences, the introns. Studies have revealed that the coding sequences are present in every individual because they code for proteins that drive the life process. These sequences have great similarity in individuals and display limited variation. On the other hand, the non-coding sequences portray a high level of variation and form the basis of DNA profiling. Basis of Fingerprinting DNA profiling is currently the most powerful tool in individual identification. It utilizes the variation of the non-coding sequences to pr oduce unique profiles for each individual (Starr et al 247). The variation in these sequences is too high and this minimizes the probability of two individuals having identical profiles to virtually zero. Due to their high level of variability, geneticists call them hyper- variable regions. These regions consist of about ten to fifteen core sequences that may repeat themselves severally at different locations in the chromosome. The non-coding regions appear in between the coding regions. The frequency of repetition of these highly variable regions results to the differences among individuals. Studies indicate that only identical twins produce similar DNA profiles. The reliability on DNA profiles overrides the traditional fingerprints. The environment contributes greatly to the patterns of the fingers of an individual and the method presented its challenges. DNA fingerprinting presents a great potential in providing accurate profiles that can differentiate two individuals. Closely re lated individuals display a level of similarity in the profiles depending on the level of correlation. Procedure of Running a DNA Fingerprint DNA fingerprinting is laboratory technology involving several procedures. The discovery of restriction enzymes, which cleave DNA at specific recognition sites, formed the stepping-stone to DNA fingerprinting. The initial step in DNA typing is the isolation of DNA from the sample. Samples may be blood, cells, saliva, urine, hair follicles, bones, teeth, and hair fragments (Read 21). Geneticists recognize the existence of both nuclear DNA found in the cell nucleus and mitochondrial DNA in the mitochondrion. The amount of sample available determines the type of DNA isolated. In cases where small samples are available
