Microplastic Pollution

Microplastic pollution is an increasing problem in the marine environment. This study had five research objectives: establish if seagrass habitats are accumulating microplastics compared to sandy habits in the Florida Keys, identify if there are any microplastics present in field collected sea cucumbers in the Florida Keys, determine the number of microplastics in Pensacola Beach sediment, determine the number of microplastics in St. Joseph Bay sediment, analyze field collected sand dollars in the Panhandle of Florida for microplastics, and conduct a laboratory experiment on the sand dollar, Mellita tenuis, to determine if they are selecting for microplastics. Microplastics were extracted from samples using a saturated CaCl2 solution, and visual examination. Both seagrass beds and sandy areas in the Florida Keys contained microplastics. Sediment in Pensacola and St. Joseph Bay both contained microplastics. Sea cucumbers collected in the Florida Keys, and sand dollars collected in the Panhandle of Florida, had microplastics as part of their gut content, suggesting they may make useful animals for monitoring nearshore environments for microplastic pollution. In the laboratory, M. tenuis ingested microplastics in slightly lower proportions compared to surrounding sediment. CHAPTER I INTRODUCTION Microplastics Plastic production has been increasing worldwide for the last sixty years, with manufacturing increasing about 9% each year. In 2007, 260 million tons of plastic were produced (PlasticsEurope 2008). The high durability, low cost, and light weight have made plastic the material of choice in creating many products (Andrady and Neal 2009; Thompson et al. 2009). The incredible success of the plastic industry was unexpected, thus when plastics were first introduced, dangers to the environment were ignored (Stefatos et al. 1999; Derraik 2002). In 2010, between 4.8 to 12.7 million metric tons of plastic entered the marine environment, and the amount is increasing each year (Jambeck et al. 2015). The consequences of plastic entering the marine environment has only been recently recognized, and is still not well understood. The combination of the long time it takes for plastic to degrade, its ability to concentrate contaminants, and the ingestion by marine organisms are collectively raising concerns for the health of the marine environment. Microplastics are defined as plastic pieces less than 5 mm in size (Arthur et al. 2009; Van Cauwenberghe et al. 2015), although different studies have contrasting definitions of microplastics making comparisons difficult (Van Cauwenberghe et al. 2015). Primary microplastics are intentionally made 5 mm or less for use in cosmetics, cleaners, and industrial scrubbers. Microplastic pellets are the raw plastic material from which larger plastic items are made (Wilber 1987; Costa et al. 2010). Secondary microplastics are derived from larger plastic sources by mechanical, photolytic, or chemical degradation (Mathalon and Hill 2014; Alomar et al. 2016). Examples of secondary microplastics include irregular fragments from macroplastics, and fibers from clothes and nets. Plastics enter the ocean from sources on land and on the sea. About 75% – 90% of plastic debris is land-based coming from littering, and improperly maintained landfills. Areas with higher river input have a higher concentration of microplastics (Vianello et al. 2013; Van Cauwenberghe et al. 2015). The other 10% – 25% come from direct inputs to the ocean, such as shipping, dumping garbage, and fishing (Wessel et al. 2016). Human population density is a large contributing factor in the distribution of microplastics in the ocean and on shorelines and, not surprisingly, heavily populated areas have higher concentrations of debris compared to areas of low population density (Van Cauwenberghe et al. 2015). Beaches near urbanized areas may have 3.3% of the sediment composed of microplastics by weight compared to 0.12% in more isolated areas (Carson et al. 2011; Van Cauwenberghe et al. 2015). With human population growth, more waste is entering the oceans via sewage outfalls, rivers, littering, and industrial discharge (Claessens et al. 2011; Derraik 2002). Over 90% of the variation in the abundance of microplastics on shorelines can be explained by the population density near the area being sampled (Barnes 2005; Browne et al. 2010). Population size and waste management systems largely determine which countries contribute the greatest amount of plastic marine debris into the ocean. If waste management does not improve, there will be an order of magnitude increase in the amount of plastic entering the ocean by 2025 (Jambeck et al. 2015). Documentation of microplastics in the marine environment began in the 1970's when they were first described in the water column (Carpenter and Smith 1972; Carpenter et al. 1972), and on shorelines (Gregory 1977; Gregory 1978; Shiber 1979; Shiber 1982). Thirty years later occurrence of microplastics in the sediment was first described (Thompson et al. 2004). Types of microplastics in the environment include: fibers, fragments, films, and microbeads found in the water column, along shorelines, and in sediment in every marine environment (Wright et al. 2013b; Alomar et al. 2016). Fibers are the most abundant type of microplastic found by many studies, and may be composed of nylon, polyvinyl alcohol, and polypropylene (Browne et al. 2010; Claessens et al. 2011; Alomar et al. 2016; Taylor et al. 2016). Nylon fibers come from clothes, carpets, ropes, and nets. Polyvinyl alcohol fibers are from fishing gear such as fishing lines. Polypropylene fibers are derived from ropes and carpets (Claessens et al. 2011). Washing a single piece of clothing produces around 1,900 fibers that may be released into the environment, thus fiber pollution is often greatest in areas near sewage outfalls (Browne et al. 2011; Alomar et al. 2016). More than four microplastic fibers per gram of sediment have been found in samples taken from areas where sewage is discharged into the ocean (Browne et al. 2010). The ability to determine if a fiber is plastic, or some other type of material, is crucial for accurate estimates of the amount of plastic in the environment. A study in the English Channel found that over half of the fibers ingested by fish were made of cellulose compounds (Lusher et al. 2013)Fragments are usually broken down from larger materials that may be made out of a variety of polymers including polyethylene, polypropylene, polystyrene, polyvinylchloride, polyester, nylon and polyamide (Browne et al. 2010). Polyethylene and polypropylene are found in plastics like bottle caps, fishing line, wrappers, cigarette butts, and straws (Wessel et al. 2016). Polyethylene and polypropylene production uses half of the oil consumed for plastic production (Browne et al. 2010). Plastic films are used in products such as balloons, frozen food packaging, and medical supplies (Claessens et al. 2011). These one-use plastics degrade over time becoming microplastics. Microbeads function as scrubbing agents in face washes and cleansers, and are made from polyethylene, polypropylene, and polystyrene (Claessens et al. 2011). Presence of microbeads in Nieuwpoort Harbor, Belgium, the largest yacht harbor in Northern Europe, was ascribed to transport by several rivers flowing into the harbor (Claessens et al. 2011). Castaà ±eda et al. (2014) found a high concentration of microbeads in the Saint Lawrence River coming from industrial sewage. Microbeads have a higher density than many plastics, so it is hypothesized that microbeads settle to the bottom before being transported further offshore. While this type of microplastic is not normally the most abundant in the environment, microbeads have been used in many laboratory experiments, and marine organisms are known to ingest them (Setà ¤là ¤ et al. 2016).

Performance Indicator Case Analysis

PRODUCT FLOW ALONG SUPPLY CHAIN: SOURCING IN CHINA vs. HONG KONG They are many aspects involved making a decision on which styles to source from China and which styles to source from Hong Kong. The differences between the producing the products in China and Hong Kong are: * ORDER SIZES: The minimum production quantity for a style in China is 1200 units while in Hong Kong it is 600 units. Thus Hong Kong factory can produce smaller order quantities effectively, thus enabling the company’s to increase the range of products it offered and manage the inventory risk.Reason: This difference in production abilities is mainly due to the high skilled labor coupled with shorter production lines in Hong Kong compared to the low skilled and long production lines in China * LABOUR The workers in Hong Kong worked about 50% faster compared to the workers in China. As a result the parka line in Hong Kong requires only 10 workers to complete all the operations whereas the parka line in China re quire up to 40 workers. This resulted in the longer production lines.In spite of the high quality of workers in Hong Kong, the unemployment rate in the country is very low and most of the younger workers prefer office jobs. Hence it is difficult to acquire labor in Hong Kong. Reason: The differences in the efficiency might be due to the variances in the trainings given to the workers in China and Hong Kong. The workers in Hong Kong were more cross functional and were trained to work in broader range of jobs compared to the Chinese workers. * TOTAL COST The overall cost of production is lower in China as compared to Hong Kong.Though there is a definite cost advantage, there are strict quota restrictions by the U. S government on shipping goods from China when compared to Hong Kong. Reason: The lower production costs in China can be mostly attributed to the low wage rates compared to the wage rates paid in Hong Kong. The workers are paid $0. 16 per hour in China compared to $3. 84 per hour paid in Hong Kong. * QUALITY Another main difference between sourcing in China and Hong Kong is the quality of the products. The quality and reliability of the products from China is relatives low when compared to Hong Kong.Reason: The difference in quality could mainly be attributed to the labor skill and efficiency in both the regions. The workers in Hong Kong have the capability to ramp up the production faster and thus they had the shorter production lines. Longer production lines in China led to the greater imbalances both in the quality and time required in manufacturing the product. Recommendation Based on our analysis we found the order quantity for each of the 10 parkas. A detailed order quantity for each of the 10 parkas is given in appendix 3. Steps for calculating order quantity: For Obermeyer we have Cu = $27 and Co = $9 from this we calculate CSL for Obermeyer = . 75. This means that there is 25% probability for a stock out applicable for each of the 10 parkas. * We used two standard deviations for the normal distribution of demand. * By using the formula Q=Z. S. D+mean for 25% stock out the overall quantity to be ordered is calculated to be 26412. * Since we need to order 10,000 units the summation of order quantity of all the 10 parkas is equal to 10,000. * We assume that the demand for each of the 10 parkas will be in same proposition.Using this we calculate for Z; Z=1. 06. * Using the z value, mean and standard deviation we calculate the order quantity for each of the 10 parkas. (See appendix 3) * Also total expected profit for 10 parkas is approximately $2. 3 Million and average left over quantity is 69 units per parka.

Case Study Example The purpose and the competitive strategies that give an organisation an edge over the competitors are known as the strategies of the organisation. Goals are sometimes stated in the company intent that is published at the start of a year. The strategies define the action plan that is adopted by the organisation so as to efficiently allocate the available resources and achieve the goals. Thus the scope of operations and the relationship that exists between the employees, competitors and customers are defined by the goals and strategies of the company. The employee turnover rate at Printzhof Press was very low and the leaders helped to achieve that end. The sales model of Printzhof was different than its competitors. Whereas most other publishing houses had â€Å"sales rep† who were in charge of contacting different professors and customers in a wide range of disciplines, Printzhof had â€Å"publishing rep† that focused on limited number of disciplines. Thus Printzhof used the niche strategy and catered to a lesser number of disciplines. Their publishing reps made it a point to attend a number of professional events that would inform them about the latest trends in teaching and research. After detailed analysis they would get in touch with the experts who would like to develop a working relation with the publishing house. Structure of a company is the hierarchical structure of the lines of authority, rights, duties and communications that exist in the same. It helps one determine the roles, responsibilities and power that exists in an organisation and the flow of information in between the different levels. It also helps an organisation identify each post, the functions that are expected from that and to whom that person holding the post would report to. This organisation structure assists an organisation in achieving the goals that have been set by the same. Generally in a centralised organisation

Writing a journal - Essay Example Taking a nap has also re-charged me. I find that if I precede my study hours with activities that result in high energy for me, I am able to study well later. The distractions for me come mainly from getting off-topic to whatever is being discussed in class. These include mood swings and an inability to concentrate that is resulting in me getting distracted. I procrastinate whenever I have to submit an assignment and this is because of partying and spending time away from my room. I plan to reduce the time that I spend with friends and instead devote this time to studying and preparing for class. The mistake that I did when I prepared my schedule was to lay too much emphasis on self-study in the sense that I allotted too many hours for this. And, when I tried to live with this schedule, I realized that I â€Å"planned to work† but did not â€Å"work to the plan† with the result that during the time I was supposed to work, I was distracted by activities like cleaning my room and taking a nap. In the next draft of my schedule, I plan to ensure that I take more part in group activities that revolve around study and assignments rather than talking gossip. Further, I intend to cut down on the time spent talking to my

The Role of Black Holes in the centers of Galaxies Essay

The Role of Black Holes in the centers of Galaxies - Essay Example In the Milky Way, the supermassive black hole is known as Sagitarrius A*, which is read as â€Å"A-star† (Naeye & Gutro, 2008). Sagitarrius A* is known to be â€Å"27,000 light years from the Earth [and] is four million times bigger than the Sun† (Ghosh, 2012). However, NASA reports Sagitarrius A* to be 26,000 light years away from the Earth, and not 27,000 (â€Å"A Mystery,† 2002). In fact, the existence of black holes has long been theorized by British astronomer Sir Martin Rees in 1974 and, according to him, â€Å"Supermassive black holes [or] ones with a million or even a billion solar masses might exist within the centers of some galaxies† (â€Å"A Mystery,† 2002). According to Durham University astrophysicist Ian Small, â€Å"The black holes [that we studied] are seen precisely at the point where they can have the most influence on the properties of the galaxies they reside in† (qtd. In Lovgren, 2005). This means that if the supermassiv e black holes are located at other points in the galaxy except the center, then it cannot exert equal influence on all parts of the galaxy. In short, for it to exert an almost equal gravitational force on every part of the galaxy, then it has to be at its center. The same principle works if the supermassive black hole is to release energy towards every part of the galaxy it is in, but this release of energy is merely hypothetical. According to Professor Richard Genzel of the Max Planck Institute for Extraterrestrial Physics, â€Å"The center of the galaxy was a â€Å"unique laboratory for the study of the strong gravity, stellar dynamics and star formation with a level of detail ‘never possible beyond our galaxy’† (qtd. in â€Å"Black hole,† 2008). This means that there must be one good reason for the supermassive black hole to eventually reside in the galactic center other than position. Genzel’s hypothesis is therefore the possibility that the ph ysics of the center of the galaxy is unusually different from the rest of its parts. Perhaps then there is a much stronger gravitational attraction as well as different principles of stellar dynamics and star formation towards the galactic center. Furthermore, according to Cain, the center of the galaxy, where the supermassive black holes reside, serves as the place where â€Å"every galaxy serves to focus and concentrate material as the galaxy was first forming† and it is also possible that this is the same exact point â€Å"where the black hole formed first, and collected the rest of the galaxy around it† (Cain, 2008). The aforementioned statement means that the possible origin of the galaxy may in fact be the exact point where the supermassive black hole is located and perhaps the galaxy still continues to grow from that central point. The implication of this theory is that, if it is true, then much constructive material is located in the black hole and that the gal axy is in fact never growing old and its parts constantly being replaced by these materials from the black hole. Another observation of Lovgren (2005) is that, according to scientists, â€Å"pairs of galaxies – and their black holes often merge together [thus producing] tidal forces [that] drive a lot of gas toward the center of the

International law and organisation Essay Example | Topics and Well Written Essays - 1500 words

International law and organisation - Essay Example Since there is no common governing power that supervises all countries, despite the existence of international organizations such as United Nations, states find themselves unable to trust each other. Thus, they usually treat each other as possible opponent that could grab them anytime. On the other hand, the modified structural realists believe that since there is anarchy in international relations, the weaker states have to look for means in order to protect its security and interest, as opposed to the powerful states, which tend to resist regulation or control of their movements. Similar to the modified structural realists, neo-liberal institutionalists believe that adherence to international legal principles would help promote transparency in international dealings, reduce transaction costs in international trade, intensify strict monitoring and enforcement of contractual obligations, and eases imposition of penalties for violation thereof. Voluntary observance of the international legal principles would encourage more cooperation in the international arena that would somehow grant long-term benefits, especially in the financial aspects. The hegemonic stability theor... e theories point to only one thing: the creation and observance of international legal principles are supported by the quest for protection of self-interest by the international stakeholders. Clearly, an independent state would not want to impose upon itself a rule that would ultimately restrict its freedom, if it will not reap any benefit from it. It cannot be denied that this voluntary adhesion to certain legal principles is no longer governed or motivated by the spirit of altruism. States need to protect themselves. Nobody can do it better than themselves. In the humanitarian aspect for example, every state must choose to create a standard that would protect its people against unwarranted human rights violations. This is especially true in terms of physical violence where no specific ideology or religion could divert or amend the standards for all human beings because of the basic knowledge that all humans are equal in feelings. If a state for example would think of exempting itself from the international standards of human rights, common sense dictates that it should prepare itself for possible retaliation in the most inhumane way since the state itself does not observe any standards for physical violation of its citizens. A classic example on this one is the law on war. The killing of a war prisoner is generally prohibited. If the United States for example would kill an Iraqi soldier who was left by his troops during a fight and who was captivated by the American soldiers would be killed, Iraq would then have every reason to kill an American war prisoner because the United States in this case was the first one to violate the rights of such war prisoner. To create and obey this particular international legal principle is then more of a reciprocal benefit

How an experience of attending a concert may be affected by your Essay

How an experience of attending a concert may be affected by your expectations of it - Essay Example The mass media with the aid of different technologies often provide the viewers or the audiences with synthetic realities like animations, fast as well as slow motions, computer simulations and zooms. The broadcasts in the televisions deliver a clear view of any events or actions rather than experiencing the real event. The different effects of mass media include the deliverance of valuable information as well as news to the people, informing the public about various government programs along with policies, entertaining people and promoting various trades and industries through advertisements (Marikkar, â€Å"An Introduction to Mass Media and Their Effects and Roles in Society†). Thus, it can be stated that the mass media imposes crucial impact upon the individuals and the society at large. Thesis Statement In this discussion, a critical examination about the way an experience of attending a concert may get affected due to the prior expectations in comparison to the experience of the same event in a mediated form will be taken into concern. Moreover, a detailed analysis of both the types of experiences of the event in terms of various relevant conceptions and theories will also be portrayed in the discussion. Discussion It has been observed that the notion of synthetic experience or a mediated type of experience is qualitatively different from a real experience. The aspect of real experience principally originates within the natural sensory envelope of a person i.e. constant vision sounds among others which arises from the events occurring at their own paces in real time within the reach of the sensory capabilities of a person. Conversely, the facet of synthetic experience arises from the conceptions which do not possibly originate within the natural sensory envelope of an individual. During the years of twentieth century, the public has known to become quite familiar with an informative environment which is based upon real experiences blended with unrea l or synthetic experiences. The motion pictures usually provide synthetic experiences to the people and they self-consciously attend them as a recreational event. In this regard, both real as well as synthetic events are gradually presented to the audiences of mass media and hence every individual experiences the mixture of both the events. Through the expansion of mass media, synthetic events have increasingly become more persistent in comparison to real events in modern life in the form of synthetic experiences. The mass media has been successful in attracting the attention of a huge number of people and it has been recognized in this context that much of the current day experiences are entirely different from the experiences prior to the years of twentieth century (Funkhouser & Shaw, â€Å"How Synthetic Experience Shapes Social Reality†). However, there exist both synthetic as well as real experiences with regard to attending a particular concert. The

Case analysis Essay Example | Topics and Well Written Essays - 2250 words

Case analysis - Essay Example This paper analyzes one of the managerial blunders that were taken by a company. This is in regard to the construction of terminal five, at the Heathrow Airport, in Terminal Five. The company that was responsible for constructing this terminal was British Airways. British Airways is the largest airline carrier in the United Kingdom. This is based on the number of fleets it operates, the size of the company, and the international destinations of the company. The intention of the company in constructing this terminal was that it should give it the capacity of increasing its revenue, and improving its public status and image. However, this turned out to be one of the strategic blunders of British Airways. This paper would examine this blunder, in relation to the theories of strategic management. Initially, the air transport industry was a government owned and managed industry. This is in almost all the countries of the world. However, because of the emergence of capitalism, and liberalization of the economies, various governments began to liberalize the airline industry, and allow for private ownership. This includes countries such as the United Kingdom which has allowed for the private ownership of the airline industry (Barney and Hesterly, 2006). For example, the British Airports Authority is a private company that manages and operates six airports in the United Kingdom, and this includes the London Heathrow Airport. It is at this airport that British Airways decided to construct the terminal five, which was to enable it expand its operations, and increase the number of its passengers. It is important to explain that the airline industry is driven mainly by profits, and this makes it to be one of the most competitive business industries in the world (Fojt, 2006). This is the reason why there is an emergence of other airline companies operating in the United Kingdom, and they include Virgin Atlantic, British Midland International

Style & Genre - Essay Example Moreover, it comforts people in rituals and in expressing physical fitness as well. The fact that music is commonly listened does not mean everyone is a fun and for those who listen to it choose according to their tastes. It is also chosen according to age and references of various groups. It makes people relax and reduce unhelpful thoughts in life hence eradicating or reducing stress in day to day life. In addition to that, it enhances mood management and reduces loneliness. It keeps people busy in their workings and reduces idleness thus reducing time wasted in bad things such as involvement in drugs. Duration- this refers to sound length and silences in between music that includes beats and rhythm. This can be seen during silence period, where beats make the music moving, thus enhancing music sweetness. Pitch- this is shown by the highness or lowness in music sound. It is one of the aspects considered when composing a song. If the pitch is too high, sound is heard to be irritating and does not draw listener’s attention. Dynamics- this is characterised by sound volume of the song. It is the softness and loudness of the music and how individual emphasises on sounds. If the volume is too high to listeners, then many will not create interest to it though it is not recommended to be too soft. Tone color- this is what allows the music listener to differentiate or identify sound sources or combination of sound sources. If the individual’s voices are combined with the instrument sounds, the music becomes more interesting hence drawing the attention of many. Formal and technical rules- Johnson, Fulcher and Ertman (2007) emphasise that, these rules are the most considered in music composition. Many may not put into consideration the other rules as such, but these are as a must to be applied in music language. This is because the music should have a well grammar sentences and

Nursing research - Essay Example On the other hand, the analysis of data in the research study involved a process of assembling raw data and obtaining a set-up of the overall nursing unit. By establishing this set-up, the data collected is credible since it provides an individual with a picture of the unit without a complete analysis, which is evidence of scientific rigor. Other than credibility, Meyers and Sylvester (2006) identify the importance of data transferability as evidence of scientific rigor in research. In line with this, transferability is the representativeness of the research study. In this study, Scott and Pollock understand the context they are investigating since they collected data to extent that they were satisfied that they fully addressed the issue under study. Consequently, the researchers provide a rich text that contextualizes the phenomenon in a descriptive approach that makes the findings of the research study applicable to other facilities. Dependability, which is the level of the reliabi lity's  coding procedures, is another noteworthy approach of establishing scientific rigor in qualitative research (Meyers & Sylvester 2006). ... The  other  step involved the first author documenting all the personal biases and the expectations before engaging the respondents. Finally, the researchers completed a comprehensive audit trail that concluded, interpreted, and gave recommendations based on the data obtained from research (Scott & Pollock, 2007). Through an audit trail, the research study effectively establishes the dependability of the research study, which is proof of scientific rigor in a research study (Meyers & Sylvester, 2006). In addition, the audit trail is evidence of the conformability of the research study since it provides an opportunity for reviewers to â€Å"review in detail what the researchers did, why they did it, and how they arrived at their conclusions† (Meyers & Sylvester, 2006, p. 3). As a result of  the  concept of the conformability nature of the research study, the study can be said to have evidence of scientific rigor. The research study clearly states the implications of the findings in practice. In this case, the study identifies the implications of the study in hierarchical structures of authority and approaches that necessitate utilization of research in the workplace. On the other hand, the study identifies the implications of the study in the location of work and a routine work area. Hence, the findings identify conditions that support utilization of research in the work area setting. In addition, the research study identifies the implications on working ethos by identifying the requirements for research utilization in individual nurses and their implications in research. Moreover, the study provides implications of nurses’ knowledge on research utilization by providing the values

Life today is better Essay Example for Free

Life today is better Essay Nowadays life is more comfortable, convenient and better than it was a century before. Modern facilities for health, education, communication and transport have added a lot in bringing betterment to the life of people. Advances in technology have provided people with many ways to spend their leisure time and they also have more opportunities to utilize their physical and mental abilities to achieve a better living standard. Technology and education have got much better as compared to the past as there are more schools, colleges and universities giving basic and modern education. Subsequently, it has revolutionized all the sectors of society. For instance, in the past 100 years, research surveys indicate that millions of people died due to disease outbreaks and absence of cures and appropriate health facilities. But now the mortality rate has significantly reduced because there are hospitals available almost in every town, equipped with basic emergency requirements. Medical research and inventions have eradicated many diseases from the world. Communication has become much easier and fast as internet, mobile phones, television are available nowadays. There is no need to write long descriptive letters and wait for the response for long time. One can talk and even watch his loved ones with only a single click. They provide a better source of recreation too, thus helping to get rid of boredom. Similarly, infrastructure has been improved hence it has upgraded the standard of travelling. One can travel long distances using airplane in few hours while it was not possible some years ago. People had to travel for days to cover long distances on animals, keeping heavy luggage and food with them. Development in industrial sectors has opened new areas for work to earn a living. It has introduced a wide range of career choices so that one can opt for what he likes to do instead of sticking with the occupation of ancestors. It can be inferred from the above arguments that standard of life is far better than it was in the past. People have more facilities and choices for spending and maintaining their lives. It has all happened due to the advent of education and technology that was absent in the past.

Different Types Of Portable Buildings Construction Essay

Different Types Of Portable Buildings Construction Essay Portable steel buildings are made from different components and are prefabricated at a different location. Portable steel buildings are used in an industrial environment, for various purposes, like storing equipment, shelter for workers, temporary offices and security check posts. These buildings are made from lightweight and high strength steel that ensures portability and long life. The base of these buildings has two tubular openings, which are used to lift the building with the help of a forklift. Apart from the basic steel framework, they are covered with a layer of galvanized steel for added strength and finish. The base of these buildings is covered with a thick layer of fiberglass to enable insulation against electric shocks. The interiors are designed according to the needs of the user. The floor is covered with thick plywood planks or vinyl floor tiles to give it a smooth finish. The building has openings for doors and windows, which can be fitted with metal, plastic or wooden doors and windows, as per the needs of the user. They have inbuilt fixtures and fittings for electrical wiring, telephone wiring and air conditioning. The walls and ceiling are covered with fire resistant material for added safety. Portable steel buildings are available in different sizes and can be customized according to requirements. New doors and windows can be added to the existing framework and existing door and window positions can be altered to suit different work environments. Laboratory tests conducted on steel buildings, with the help of earthquake simulation machines, have shown that these buildings are resistant to high magnitude tremors. Small steel buildings can be installed inside standard houses where family members can take shelter during an earthquake. People can stay unharmed, as the steel structure is unaffected even if the whole house collapses onto the building. Portable Modular Buildings Portable modular buildings are made from different components, which are prefabricated and assembled onsite. Modular buildings and the components for prefabricated buildings are manufactured in a controlled, factory environment. A portable modular building has all the necessary components, like walls, floor tiles, windows, plumbing, electrical wiring, heating and cooling systems. Simply put, a modular building refers to any building or structure that is pre- constructed in a factory. A modular building is very different from traditional site-constructed, permanent buildings. These structures are very versatile and are available in different shapes and sizes. They can be used for different purposes, such as school classrooms or bullet- proof security spaces. They can be used as short-term spaces or as a permanent facility. They can be used as stand-alone structures or built inside an existing structure. Most of these buildings are made from lightweight and high strength steel or aluminum. Apart from structural advantages, a portable modular building offers other benefits such as low cost, quick possession, customized quality, extension and rearrangement. The most significant advantage offered by these buildings is that, they can be assembled in a very short period. This is due to the planned, design blueprint used for building these structures. Building designs are lab tested before they are cleared for final production. This enhances quality and reduces manufacturing time and the cost. It is important to be definite about specific requirements. National and local construction standards must be followed during the installation of modular or pre-fabricated structures. The type of foundation laid during the installation process, should comply with locally prescribed model construction codes. The use of portable modular buildings will only increase in the coming years. According to research, more than 75 percent of all building constructions will use some form of pre-fabrication, within the next 10 years. Portable Commercial Buildings Portable commercial buildings consist of different components. They are prefabricated in a factory environment and assembled onsite. Components used in these buildings are manufactured according to design specifications provided. They are then delivered to preplanned building sites for installation. A portable commercial building can be customized to include different components such as walls, floor tiles, windows, plumbing, electrical wiring, heating and cooling systems. A portable commercial building refers to any building or structure that is pre- fabricated in a factory environment. Portable commercial buildings are very different from conventional steel and concrete buildings. These structures are very versatile and are available in different shapes and sizes. They can be used for a variety of purposes such as office spaces, warehouses and manufacturing units. They can be used as temporary spaces or as a permanent facility. The basic framework of most commercial buildings is made from lightweight and high strength steel or aluminum. Apart from the structural advantages, a portable commercial building offers other benefits, such as low cost, quick possession, better quality, extension and relocation. The most significant advantage offered by these buildings is that they can be assembled in a very short span of time, unlike permanent buildings. Each and every building design is tested in a laboratory before they are cleared for final production to enhance quality and reduce manufacturing time and cost. Commercial users, such as corporate organizations, need to be sure of their requirements before selecting a particular type of portable modular building. It is important to follow the construction standards prescribed by government agencies, during the installation process. The demand for portable commercial buildings is expected to increase in the coming years. Market research indicates that more than three-fourth of all building constructions will use some type of portable construction within the next ten years. Portable Wood Buildings Portable wood buildings are made from different types of wooden planks and plywood boards. They are prefabricated at a different location and assembled onsite. Portable steel buildings are used in industries as well as domestic households, for storing equipment. They can also be used as temporary workplaces, shelter rooms and security check posts. These buildings are made from lightweight and high strength wood that ensures portability and long life. These buildings are designed to provide balance and can be lifted and transferred with the help of a forklift. The exterior is coated with weather resistant paint to provide protection against water and excessive sunlight that can damage the building. The base of these buildings is made from pressure treated runners, placed on concrete blocks. Floor leveling is done with the help of pressure treated lumber and shingle scraps. The interiors can be designed according to the needs of the user. The floor is covered with thick plywood boards or vinyl floor tiles to give it a smooth finish. The building has openings for doors and windows, which can be fitted with metal, plastic or wooden doors and windows, as per the needs of the user. They can be customized to include fixtures and fittings for electrical wiring, telephone wiring and air conditioning. The walls and ceiling are covered with fire resistant material for added safety. Portable wooden buildings are available in different standard sizes and can be customized according to user requirement. New doors and windows can be added to the framework and the existing door and window positions can be altered to suit different work environments. Some manufacturers offer wooden homes as complete knocked down kits, which can be assembled onsite. Users, who want to avoid the hassles of assembling these kits, can take the help of trained personnel.

The bioprocess of yogurt

The bioprocess of yogurt Abstract This report discusses the bioprocess of manufacturing yoghurt on an industrial scale. On a industrial scale the procedure for yoghurt production follows: preparation and standardization of milk, Pasteurization, homogenization, Cooling to incubation temperature for inoculation with starter culture, fermentation, post-fermentation treatment i.e. adding additive such as flavouring, fruit addition, refrigeration and packaging. In examining each step and identifying limitation, improvements in the general procedure have been suggested. Some improvements include; ensuring correct standardization of milk i.e. yoghurt standard contents are met, changes in technique used to alter fat content, effective heat treatments to kill off unwanted organisms, verification of fermentation process to give and starter culture used in inoculation provides high yields, handling is limited to avoid contamination of and damage to the final product. Introduction Yoghurt is one of the most popular dairy products consumed worldwide and is made principally on the bacterial fermentation of milk. The word is from the Turkish Yogen, meaning thick. Originating in the slopes of Mount Elbrus the discovery of yoghurt was by complete chance; when a Turkish nomads pitcher of milk was contaminated by some organism that thrived in warm milk. Since then yoghurt has been produced and consumed worldwide for at least 5 400 years and continues to be one of the most nutritious foods proving unique nutritional value to the consumer. Yoghurt is produced when a lactic acid bacterial starter culture is used to ferment the sugar Lactose found in milk to Lactic Acid which then acts on the protein to give yogurt its characteristic texture and form. Dairy yoghurt is produced using a mixed culture of Lactobacillus bulgaricus and Streptococcus thermophilus bacteria. Although the consistency, flavour and aroma may vary from one region to another, the basic ingredients and manufacturing process are essentially consistent. The general manufacturing procedure includes; Adjusting milk composition and addition of other ingredient to meet the required Code of Federal Regulations (CFR) in terms of fat and non-fat content. Pasteurization of milk to kill unwanted bacteria Homogenization of milk to ensure uniform composition Cooling of milk to optimum starter culture incubation temperature Fermentation of milk by addition of starter culture Addition of flavours and fruit Storage and packaging The implantation of this general manufacturing procedure is seen in the production of Yoplait yogurt (as seen in the flowchart below). Preparation of Milk In the production of yoghurt a variety of milk can be employed; whole fat, semi-skimmed milk or low fat milk, the type of milk used depends upon the type of yoghurt one intends to produce. However, one of the main importance when considering the type used is the absence of any material (disinfectant) or organisms that will hinder or prevent the growth of the starter organism, for example, bacteriophages which are a group of virus that can attack the starter organism causing extremely long periods of incubation (Moralee, 2002). When the milk arrives at the plant, its composition is altered before any further processing can be completed. This standardization process usually involves increasing the total solids content and decreasing the fat content. The fat content is reduced by a process termed centrifugation. Centrifugation is a separation process commonly used in the industrial treatment of milk. In this process the centrifugal force is utilized to separate insoluble from the liquids thereby resulting in the fat globules separating from the rest of the milk suspension. The milk should be kept at temperature of 40oC before entering the centrifuge (Costa Goomes, 2008). The lower the fat content the higher the lactose levels (Carpers, 2005) hence lowering the fat content will be beneficial when the milk later undergoes fermentation. Several methods can be used to raise the solid contents in milk; evaporation, addition of skim milk powder, addition of milk concentrates etc. In industrial yoghurt manufacturin g, the solids content of yogurt is often adjusted above the 8.25% minimum (Food and drug administration, 1999). Commonly the standard solids content is increase to 16% with 1-5% being fat and 11-14% being solid non-fat (SNF). Increasing the dry matter contents (solid non milk fat) not only improves the nutritional value of the yoghurt, but also provides a thicker, firmer and fuller bodied to the finshed yoghurt (Watson, 2004). Improvements Evaporation of milk prior to the fermentation process for concentrated milk (higher non-fat solid content) is utilized in order to give a better body and texture to the yoghurt. Due to the ever spiralling energy costs, the increase in cost of concentrating milk is becoming prohibitive ( Moralee, 2002). Consequently, larger manufacturing plants have begun replace the evaporation method with a new technique known as fortification. Fortification is the addition of dried milk solids to the base of milk prior to inoculation (Moralee, 2002). Several commercial yoghurt manufacturing plants are fortifying the base milk with a cocktail of milk and non milk solids (Smith, 2002). The addition of stabilizers may also be employed to improve the body of the yogurts as they increase the firmness and viscosity, preventing separation of the whey; liquid remaining after milk has been curdled, from the yoghurt, a problem know as syneresis (Watson dairy consulting, 2007). This is achieved through their ability to form gel structures in water and as a result leaving behind less free water for syneresis. Stabilizers are more important in yoghurt produced commercially as yoghurt mix has to be pumped, stirred, fruited and filled and will often break down to a runny liquid without the addition of stabilisers (Watson, 2004). The amount of beneficial stabilizers to be added to the yoghurt mixture is required to be determined simply through batch sampling experimentation by each manufacturer as Too much stabiliser and the yoghurt can take on a rubbery texture, far too much stabiliser and the yoghurt can become a hard solid mass (Moralee, 2002). Some stabilizers used in yoghurt manufacturing include gelatins, gums (locust bean, guar), pectins, and starch. Pasteurization Generally the fresh milk obtained from healthy animals is either beneficial or harmless, however, changes when improperly handled, or deterioration of the animals health can create conditions in which the bacteria are able to multiply. The large presence of unknown organisms in the raw milk would make the fermentation too unreliable and unpredictable for commercial operations (Csutak, 2005). Pasteurization is the process by which heat treatment to each particle of milk at relatively high temperature for a specified period of time is capable of killing off harmful bacteria for example pathogens, and improve the storage quality of milk by inactivating certain undesirable enzymes and spoilage bacteria (Watson 2007). Typical temperatures for milk pasteurization are 85-95oC for 20-30minutes (Smith 2002). This technique of heat treatment is also successful in achieving a more stable gel as it denatures the whey (serum) proteins. Furthermore, high heat treatment can also ensure little compe tition from spoilage organisms providing a much better environment for grown of starter organisms later in the process. It is important that the pasteurization of the milk occurs before addition of starter cultures as this ensures they act as prebiotics; remain active in yoghurt after fermentation (moralee, 2002). Improvements: Whilst pasteurization of the milk is effective in destroying microorganisms, improper handling after pasteurization can recontaminate the milk (Brock, 2005). Several safe handling practices can be employed such as sterilised equipment should be used, preferable stainless steel utensils as these are more easy to clean and durable, pure water streams should be utilize when cleansing to prevent any contamination, rapid cooling to approximately 5oC or less and storage in closed vessels before and after pasteurization to ensure unaltered quality and flavour of milk (Brock, 2005). Pasteurization can be a continuous or batch process, however, commercially it is better in continuous stirring vessels as this continuous agitation ensures every particle of milk including the foam receives the minimum heat treatment. The temperature within each vessel should be monitored with an accurate metal or glass thermometer (Smith P, 1981). Apart from utilising pasteurization, Ultra-high temperature (UHT) is another type of heat treatment that is currently being employed. In this type of processing organisms are destroyed destroy more effectively by heating the mixture for a shorter period of time, approximately 1-2 seconds, at an extremely high temperature exceeding 135oC (Dairy Science and Technology, 2007). UHT treatment essentially sterilizes the milk and allows it to be stored at room temperature for up to 8 weeks with out change in flavour (Brock, 2005). Homogenization In the commercial production of yoghurt milk is always virtually homogenize prior to fermentation in order to give a uniform product. Homogenization of milk aids in the prevention of cream that is, the fat from rising to the surface during the fermentation process. Using a homogenizer or viscolizer fat globules are broken down into much smaller and more evenly dispersed particles and subsequently producing a much smoother and creamier end product (Watson, 2007). When milk enters a homogenizer it is force through small orifices at extremely high pressures breaking down globules as a result of the high shearing forces and dispersing the fat evenly throughout the milk which prohibits the fat from rising to the top of the container (Steane, 2008). Milk mixtures are typically homogenized under pressures of 2000-2500 psi (Moralee, 2002). Additionally this process also prevents wheying off during the incubation and storage stage thus enhancing the stability and consistency of the yoghurt. O nce the homogenized mixture has been cooled to the optimum growth temperature, the starter culture is added. It is important for the mixture to be cooled to a typical temperature of approximately 45oC for inoculation as temperatures higher than this may kill off culture (Watson, 2007). Following the cooling of milk to a temperature of 40-45oC, the milk is inoculated with a fermentation culture. The main starter cultures for yoghurt production are Lactobacillus bulgaricus and Streptococcus thermophilus. The function of the starter cultures is to ferment the lactose, sugars found in milk, to produce lactic acid. C12H22O11 + H2O ? 4 C3H6O3 Lactose Lactic Acid The increase in lactic acid production corresponds to a decrease in pH levels and causes the milk to clot, or form the soft gel curd that is characteristic of yogurt. The fermentation of lactose also produces flavour compounds, acetaldehyde, that are characteristic of yogurt. The lactic acid levels can be measured by simply performing a titration with sodium hydroxide. The current minimum standards for yoghurt manufacturing require a value of at least 0.9% acidity and a pH of about 4.4 (Food and drug administration, 1999). The fermented milk is typically incubated in large sealed vats in a temperature controlled environment, temperature is monitored carefully to maintain at a temperature optimum for starter culture growth. Inoculation typically occurs at a rate of 0.5-5% (Watson, 2007). When the desired acidity, that is pH level of about 4.4 is reached, rapid cooling to approximately 7 oC is effected in order to stop the fermentation process. It is vital to note that too long or too short a fermentation process will produce a product that is inferior in either its flavour or texture. Too long fermentation will give other organisms the change to become established, with the associated risks of off flavours and smells (Morale, 2002). In the commercial production of yoghurt, emphasis is not only on the fermentation ability but also on characteristics imparted by the lactic acid cultures. For satisfactory performance the starter culture must be capable of rapid acid production, flavouring of yoghurt, production o full body and texture yoghurt. The determination of whether the starter culture activity is satisfactory or not is determined by direct microscopic counts of culture slides stained with methylene blue (Smith, 2002). In doing so there is also the benefit of observing the physiological state of the cultured cells. The lactic starter culture used for yoghurt production is thermophillic has an optimum temperature of 42oC. The two cultures (Lactobacillus and streptococcus thermophillus) can be grown independently; however, there is a higher rate of acid production when used in together (mixed strain), that is that make use of each others metabolites in order to effect the acid production efficiency. Streptococc us thermophilus grows at a faster rate producing carbon dioxide and lactic acid. The formate along with the carbon dioxide stimulates the growth of Lactobacillus (Smith, 2002). During fermentation the yoghurt mixture coagulates when the pH level drops. The streptococci are responsible for the initial pH drop of the yogurt mix to approximately 5.0. The lactobacilli are responsible for a further decrease to pH 4.5 (Steane, 2008). Inoculation of lactic starter cultures with yoghurt milk produces lactic acid, acetaldehyde and acetic acid. Improvements- As mentioned above when selecting the type of milk used in manufacture of yoghurt it is important for the milk to possess a low bacteria count, be free from sanitizing chemicals, rancid milk and have no contamination by bacteriophages. Serious economic losses in the yoghurt industry have been attributed to phage attack (Smith, 2004). Accompanying the decrease in texture and flavour, bacteriophage attacks decreases the rate of acid production. Large scale manufacturers typically have laboratory facilities to check incoming milk to eliminate the possibilities of other starter inhibiting substances (Moralee, 2002), however, the presence of bacteriophages is always a risk. Large manufacturers Phage are usually found in the drains and floor gullies of a dairy producing any cultured product, poor hygiene and a lack of general housekeeping increase the risk (Dairy Science Technology, 2007). Thus in order to reduce the possibility of bacteriophage present strict sanitation procedures would e nsure prevention of phage attack (Smith, 2004). This include; hand-washing between each handling, sterile tanks, floors and bench surface. s Also, since the starter culture is one of the most critical ingredients in yoghurt manufacture synchronisation of rate of acid production and plant production schedules is extremely vital. For example, if frozen cultures are used then a longer incubation period of approximately 5 hours at 43oC is required for acid production (Smith 2002). Similarly as noted above, maintenance of temperature is extremely important for starter culture. This is because if the temperature of incubation is too low, culture grows at such a slow rate that it is unable to adequately acidify milk and to achieve a good texture vice versa if the temperature is too high the culture is killed. Traditionally, when the lactic acid starter culture is grown in a suitable medium, small quantities will be extracted to inoculate each new batch of yoghurt. This is commonly referred to as using bulk starter. However, due to the high risk of bacteriophage infections and the delay in time when each new batch is prepared, employment of bulk starter is becoming increasingly uncommon amongst commercial producers (Smith, 2002). A new technique referred to as DVI (Direct Vat Inoculation) is fast becoming the most preferred choice which involves inoculating the yoghurt mix directly with a very large number of freeze dried starter organisms (Watson,2007). Even though there may be a longer incubation time, relative immunity to phage attack makes this a more safe option for manufacturing plants to ensure production of yoghurt is efficient every time. The design of the container in which the fermentation process is carried out in can also improve the process. Commercially there has been a shift in design of cone bottom processers to facilitate the draining of relatively viscous fluids after incubation (Carpers, 2005). Critical step in the fermentation process is the maintenance of the optimum temperature for growth of starter cultures; hence well insulted incubation vats should be utilized. Addition of fruit and Packaging At this stage fruits and addition desired flavours may be added at or prior to filling preformed pots. Common additives include, fruit flavours, colouring agents, sweetening agents. Depending on the type of yoghurt, the above fermentation process may occur before this addition of fruit or after. For example, in set style yoghurt fruit is added to the bottom of the cup and inoculated yoghurt is poured over the top, the fermentation takes place within the cup. For stirred yoghurt, the fruit is blended with the cooled ferment yoghurt and yoghurt texture can be made smoother by pumping it through a cone before packaging (Moralee, 2002). The yoghurt is refrigerated until it is required for package and transportation. Conclusion- In undertaking an engineering analysis of the bioprocess of yoghurt and exploring each step carefully it can be seen that although yoghurt follows a general manufacturing procedure. The bioprocess of yoghurt production involves preparation of milk, followed by pasteurisation and homogenisation of the milk, cooling down period, then inoculation with a lactic acid bacterial starter culture to ferment the milk. Measurement of acid production measures the success in fermenting milk. Additions of fruit and other additives are added just prior to storage and packaging. The exploitation of the fact that milk contains the sugar lactose, and when undergoing fermentation with a starter culture produces lactic acid, allows observation of how yoghurt is produced. The production of yoghurt on an industrial scale requires great improvement in the handling of the mixture to ensure no contamination, choice of raw materials will greatly affect the final product, employing a successful method to obtai n a starter culture that is free from unwanted materials and operation in fermentation vats that give efficient outcomes.

Ocean Thermal Energy Conversion (OTEC) Essay -- Informative Essay

Ocean Thermal Energy Conversion (OTEC) is the process of converting the ocean waters temperature difference at different depths into usable energy. From the solar heated upper depths of the ocean to the cooler depths below 2,000 feet a 40 degree temperature difference must be maintained to generate electricity. This is a relatively new and unheard of source of energy. Many people are not aware of the many benefits of OTEC and the impact it will have in the future as the use of fossil fuel conversion declines. Heightened environmental concerns in today's world makes OTEC an attractive alternative for energy conversion. The ocean offers a natural and renewable resource which will make it possible for converting energy this way to last for a very long, long time. OTEC is a very cost effective method of using the oceans waters for energy conversion but its use and benefits to society have been obscure to the general public. In the coming years OTEC will probably be at the forefront of ne w energy resources and a good understanding of it know will prove invaluable to power engineers of the future. How does Thermal Energy Conversion Work? OTEC is a form of solar power in that it uses the sun's energy to heat the upper depths of the oceans waters. Since the sun's energy cannot penetrate very deep depths (approximately 2000ft.) the temperature below these levels is much colder then those near the surface. Most of the solar energy is absorbed in the top layer (35 to 100 m) of water. This upper layer of warm water is very uniformed in temperature because wind and waves cause the water to circulate and mix. The temperature in this layer can reach close to 82Â ° F (28Â ° C ) from regions close the equator. Beyond this layer the temperature drops noticeably with the depth until 800 m to1000 m. At this depth the temperature is 40Â ° F (4.4Â ° C ). From here the temperature changes very gradually. The colder water at these great depths is the result of melting ice in the polar regions. The colder water has a higher density than the warmer water which causes two important events. First the higher density water will sink and displace the lighter, warm water. Secondly, the rotation of the earth forces the heavier cold water to move toward the equator. Because of this, the ocean provides a large reservoir of cold and warm water that can differ in temperature of 40Â ° to 45Â ° F ( 22Â ° to... ...implementation. The system is still in heavy research to bring these costs down and also to make improvements on the system. Although the full scale commercial size systems are not practical at this time, small scale experimental plant systems are being for further research. OTEC is expected to make an impact on the future. The Future of OTEC OTEC is a very exciting new way of energy conversion. People are skeptical about new and innovative ideas because of their unfamiliarity and lack ofknowledge about the idea. This holds true with OTEC. Many people are unaware of what OTEC is and the benefits that OTEC holds for the future of our Earth. Much more development and research must be made to make OTEC a large scale operation and to bring the cost to consumers down. This is only going to happen if people are made aware of OTEC and its many possibilities. OTEC has many environmental benefits and can produce the world s necessary energy needs for a very long time (it is after all a renewable energy source!). We are quite certain that in the upcoming years OTEC will become a much more publicized topic and greater research will come about to produce a fully sized commercial plant.

Pacific Oil Essay -- Business Analysis

The Pacific Oil Company was formed in 1902 and had been the leader in the manufacturing of a petroleum product Vinyl Chloride Monomer (VCM). This product was Pacific Oil's major product line and was the main component to the manufacturing of plastics, used in many products. In 1979, Pacific Oil had landed a major contract with reliant and had over the years establish a great working partnership. The Reliant Corporation was one of Pacific’s largest and most valued customers and Pacific Oil Company wanted to renegotiate their current contract with the Reliant Corporation, with the goal of extending before it expired. Pacific’s negotiation team, Jean Fontaine, Marketing Vice President for Europe with Paul Gaudin, Marketing Manager of VCM along with representatives Frederick Hauptmann, Senior Purchasing Manager and Egon Zinnser, Regional VP for European operation from The Reliant Corporation, where to spend nearly two year working through the extension of the contract. In the end, the contract settlement was down to a final item that Pacific was not happy about, that may my then loose the extension altogether. Facing Hard Times Pacific Oil company was facing some economic changes over the next 10 years and the demand for its VCM was going o face some fierce competition. In the next 20 - 30 months other VCM manufactures will be producing the raw product to compete directly with Pacific Oil Company. The supply of the product over the next decade was expected to grow by over 1000 MM pounds each year, nearly doubling that as each year progressed. This poses a massive threat to Pacific oil as it negotiates its contracts only five years our and is now being pressured by Reliant to only extend their contract by three years. Reliant was... ...ine and Gaudin was going to present. Reliant had done their homework on their demands, potential softness of the market and was preparing themselves adequately to be able to deal with any changes. Pacific was not as prepared at the negotiation table as Reliant, and was eventually backed into a corner on a single item in the renewed control, the option for Reliant to re-sale any VCM product they have left over. The was a major oversight on the final advice from Kelsey in securing a huge customer and giving them time in further analysis the demand and impact that the new manufacturers would cause.

Business Ethics †Discrimination Essay

Discrimination is defined as distinguishing something from something else (i. e. don’t hire him because he has no experience). Unjustified discrimination is distinguishing something from something else on a basis that is not justified (i. e. don’t hire him because he is black). The term discrimination commonly replaces the term unjustified discrimination in business, philosophy, psychology and day-to-day community life. In a just and fair society, such as we Canadians aspire to, a job applicant’s race, ethnic origin, colour, religion, sex, age, orientation, mental ability, or physical condition should not disadvantage them in career choices or job competitions. If a short Asian female firefighter can do the job, she should get the job. Conversely she should not expect to receive concessions that are not available to all; that is in effect also discrimination. Unfortunately, discrimination often arises in business in regards to hiring, job placement, wage, and promotion. Affirmative Action Ideally, discrimination should be of no concern at all; everyone should have an equal opportunity to anything. In a perfect world a hiring manager would not have to think thoughts such as, â€Å"They are disabled, they are women, they are aboriginal,† and would only think, â€Å"This person will be perfect for the job because†¦. † Unfortunately this may never completely happen. For example if a person in a wheelchair applies to be a stock person at Costco and another person who is not in a wheelchair applies for the same position the manager will be debating, â€Å"Should I hire the person who cannot walk because I want to be socially responsible? Or should I hire the person who can walk, who will probably do a better job and who I won’t have to make special accommodations for? † Another example is a man and a woman who are applying to be a nurse on the obstetrics ward; they have both just graduated and have exactly the same experience. If only one position is available who is more likely to be hired? Affirmative action programs often come into place to encourage equal opportunity. Affirmative action refers to policies or rograms that take factors such as; age, sex, race, color or religion and give preferential treatment to people that belong to an identifiable disadvantaged group, or outgroup. Cons Reverse discrimination occurs when preferential treatment is given to one person and the other is left out. For example if a woman is hired to work in an oil patch just because she is a woman and man is not hired (perhaps only because of quota requirements), he will experience reverse discrimination. This may in fact v iolate a province’s human rights code. Some would also argue that it is wrong to place at a disadvantage a current day job applicant in order to attempt to compensate for historical wrong treatment of certain categories of job applicants. Merit may not exist if affirmative action is in place. A situation could arise where an applicant may deserve a job more because he or she has more education and more experience than the hired applicant who is disabled, if the hiring was done only in the interest of a representative workplace. May condescend or offend outgroups because the people belonging to that group don’t believe they need preferential treatment in order to succeed. Affirmative action creates a perception that all racial minorities or physically disabled persons have low self image, poor job marketing skills, missed opportunities, and are in need government regulated assistance. Efficiency may be compromised if a company is forced to hirer a proportionally representative workforce. Instead of hiring the best fitting candidate, companies would be forced to seek out a visible minority or a disabled candidate. This simply is not good business practice. A company should be free to hire the best candidate. Morale and workplace cooperation may be negatively impacted by a person being hired because of affirmative action policies which clearly give special considerations not available to all. The outgroup may develop a sense of entitlement that is not supported by the majority of the workers. Affirmative action may cause a widening of the gap (and an affirmation of bigotry) instead of a diverse and inclusive work force. For example, a white man at a steel factory may think that he got his job because he is qualified for it while being angry that the Asian man only got hired because there were no other Asians working in the plant and the hiring manager did not want to be discriminating. Pros Assistance in obtaining a desired job may be necessary for members of an identifiable disadvantaged group, or outgroup, since discrimination may make it difficult to establish a career. For example, men can be excellent nurses, but if a female hiring officer doesn’t understand or embrace the benefits of diversity, the obstetrics ward would have all female nurses. Another example might be a hair dressing trainee who is in a wheelchair; this applicant may have more obstacles to overcome and more convincing to do with a prospective employer. It is not fair, or just, that these applicants would have to be much better that the â€Å"normal† kind of applicant in order to be desirable to the employer. This â€Å"assistance† is given in affirmative action plans such as requiring employers to choose the disadvantaged applicant when all other skills are equal. Affirmative action makes working in different areas more desirable. Ex, Okanagan College has free introductory welding courses for women only. If colleges did not have these affirmative action programs there would probably be less female welders. This creates an incentive for a member of an outgroup to step forward and be part of the creation of workplace diversity. Affirmative action ensures justice for those who have historically been oppressed. Although hopefully not in Canada, there may still be a stigma attached to those whose ancestors were slaves, lower class, or aboriginal and thus seen as lesser that those with good career jobs. Some people may believe that affirmative action is necessary to change the attitudes of society by mandating a diverse work force. Canada cannot ignore the fact that a few generations ago a person with mental challenges or physical disabilities would not have been offered a position if there was a reasonable candidate who was considered â€Å"normal. † Affirmative action envisions a just work place where everyone is normal because the new normal is diverse and inclusive. Affirmative action encourages a representative work force. If 2% of the community’s population is visually impaired, then in a company of 100 employees, there should be a least two people who have some kind of sight impairment. In Canada, 3% of the population is aboriginal; therefore, there should be three members of a First Nation employed at the above company. A disabled person aged 25 to 44 accounts for 8% of the population. Statistically speaking, the above company, if it were in British Columbia, should have 27 employees who are recent immigrants. With roughly 60% of Canada’s population being Caucasian, all the numbers above would create a representative work force. It could be described as a diverse, dynamic, and exciting place to work; but does it exist? By requiring the inclusion of a representative work force affirmative action will in the long term change attitudes and encourage diversity. Thesis Affirmative action programs are still necessary to ensure equal opportunities in the work place and to encourage diversity, which over time will extinguish discrimination and contribute to a just, fair, and tolerant society. History I believe discrimination stems from history. If a young person learned from parents, schools, or media that women are not good trade workers, they will continue this discrimination for generations. This is what happens in all forms of discrimination because discrimination is learned. Discrimination can be reduced in a society with the influence of laws, education, and incentives. Affirmative action mandates exposure, which with encouragement by supportive government and ethical businesses will result in workplace diversity, and that over time will influence the thinking of society as a whole. Further Discussion: Continue Affirmative Action Dimock and Tucker thoroughly discussed their views on affirmative action policies about how such policies cause problems for employment equity in Canada. Dimock and Tucker did not discuss why such policies may still be necessary and did not thoroughly discuss a solution to discrimination. Their conclusion, while pointing out that affirmative action programs have not met intended goals, does not offer concrete solutions other than education. I disagree that the young should be the only target to ensure against discrimination. Youth can be racist, sexist, and exclusive. That’s why our society has a large problem with bullying. If discrimination is a learned trait, then the youth are learning it from above, and that is precisely the target of affirmative action. I believe affirmative action should still be used to some extent in order to encourage diversification. I think a combination of education and the experience of exposure is more useful that a single target group (such as educating the young). If groups (young, school aged, post secondary, and the work force) are created with diverse and representative participants, the likelihood of all groups beginning to like each other because of repeated exposure is much higher then if they remain separated. Well informed members of society who have personal experience with diversity are the least discriminating for several reasons: †¢They have been educated not be discriminating (from classes like this). †¢They have been put together in groups with all different types of people, and †¢They have become comfortable with that diversity. The result is that they have learned to be less discriminating than their peers or previous generation. For example, a white 18 year old’s great grandparents may have been what is now considered racist toward black people. In the grandparent’s time racism, even segregation, was thought of as perfectly normal, and those views were passed down generation to generation. However, through education and exposure racism was slowly extinguished until we have a grade 12 student who welcomes a new immigrant from Zambia. Instead of being completely racist like his great grandparents the 18 year old now only believes the stereotype that all black people like rap music which he hates. The next generation will (hopefully) not even notice that a black person is in the group. If affirmative action continues it will help the top (the existing generation of employers) meet the bottom (the well informed and accepting job applicant) and the result will be a tolerant, inclusive, and diverse work place. The attitudes of the work place will in time influence society as a whole. Conclusion I was lucky enough to learn about discrimination in both psychology and philosophy class in the same week. Although solutions are not offered in this paper, I believe discrimination can be eliminated through education and diversification. If it were normal to have a representative and diverse â€Å"melting pot† of opportunities and experiences, there would be no need to practice discrimination. Diversification is good. It makes a community tolerant and compassionate; it makes a secure and exciting place to live. Including all groups in all employment opportunities will ultimately create a better society – the melting pot that Canada so prides its identity in. Affirmative action plans ensure that the work place will contribute to this pride.

Last year I did my placement in Cork Simon Communities Outreach project

Last course of instruction I did my placement in bobsleigh Simon Communities Outreach show. I re bothy enjoyed this placement and as I had a lot of fellowship on this show I clear-cut to do my familiarity Development hear on the Outreach hold. I realised magic spell movementing on the Outreach police squad how signifi provoket the chair was because when young state startle become involved in passage life they do so because they inhabit no separate(a) option. M each give way situations of acute family breakdown or lurid situations. They may obtain been exposed to alcoholism, dose addiction, abuse and have lived under the reach out of poverty and unemployment. avenue life seems to me akin an insecure, lonely, frightening and dangerous situation for any person to find himself or herself in. alas good deal living on the streets atomic number 18 quickly exposed to alcohol, doses, crime and prostitution. many a(prenominal) people do not know how to ca-ca help and many have lost contact with operate. For the most graphic symbol people who are out of family unit are not easily identified.They menstruate around and dress similarly to early(a) people. They have however, no consistent maintain or care and nowhere they holler home office. For the most part they are invisible. This is where the Outreach Street Services importance comes in The Outreach group has a good understanding of the situation among people on the streets. Outreach contacts people out of home at risk. Outreach befriends people and builds trusting relationships with people. The Outreach team provide information about avails provided and the location of these services. Oliver Hoegener created The Yellow Leaflet which Simon published and the Outreach team always carry these leaflets to give to new- do people on the streets of bobfloat. Outreach also puts people in contact with services and tout ensemble street work is documented.HistoryThe Simon association was established in Ireland in 1969, thither are now 4 Simon Communities in the Republic of Ireland capital of Ireland, Dundalk, Galway and of course Cork which was hardening up in 1971.The philosophy of the Simon Community is the framework, which guides the communitys policies, practice and sidereal day-to-day shed bloodning of its projects. The point principles exercise set the parameters within which the countg work and residents live part in the community. The communitys philosophy is based on Acceptance, Community, Long-Term economic aid and Campaigning. The philosophy also embraces and includes, A entirelyegiance to justice, sharing, creating space for people, being as popular as possible, being part of the massiver community, providing care, brook and solidarity, valuing relationships, encouraging participation, inclusiveness. The community also has a strong willing ethos.The communitys insurance is to endow people, to encourage independence, to encourage peopl e to fulfill responsibility, to be inclusive and to facilitate those who hankering to tackle any difficulties they may stage such as alcohol and drug addictions etc. Change is not a primary focus, though it is facilitated where possible.There is a strong emphasis on Confidentiality in Simon, all matters relating to residents remains confidential and all people involved in Cork Simon Community must bear in mind that all clients have a right to privacy. This enables trusting relationships to be make within and betwixt various members of the community. entirely thespians must respect clients as individuals with the aptitude to make decisions and changes in their lives, in washy of their beliefs and values.The Outreach project is a new project of the Cork Simon Community. Since January 2002, the two Outreach workers (Carmel Moore & Oliver Hoegener) have been doing intensifier street work in Cork. The project is targeting rough sleepers and offers easy access to nourishment an d advise on a wide range of issues. One of the main aims of the project is harm reduction and prevention as easy as making and maintaining contact with service users on the street.The Outreach team liaises with other agencies such as dose and inebriant service, the Homeless Adolescent Unit and the other Drug Task Force Projects. Outreach link up in with a wide public figure of other groups in the city e.g. YMCA, Gardai, gray Health Board, local community groups, younker workers etc. Outreach works in coaction with the existing Youth Homeless Drug Prevention Project as well as with other Simon projects, such as (1) The shelter where the Outreach worker and shelter staff can establish times that the outreach team can bring people into the create to gain access to the shelters services. (2) Day substance again the outreach team works from the day centre in befriending people and create new relationships with rough sleepers. (3)The Soup break loose The nightly soup run meets between 60-80 people each week few are sleeping rough while others are living in the cliquish rented sector or in fellowship flats. The Soup Run provides hot meals, blankets, advice and gild for the homeless.In March 2002 the Outreach team set up a Lunch run, they were apprised of the need for a weekend service because places uniform the Upper Rooms solely provide a Monday to Friday service and a lot of Corks homeless people were subordinate solely on the soup run at weekends as their only character of food, similar to the soup run, the lunch run gives out tea, soup, sandwiches and fruit in the eventide around the streets of Cork city, I consider this was an excellent service to set up because while on placement I did the lunch run and it proved to get genuinely popular after a few weeks of being established, it is only the Outreach workers which do the lunch run. The two Outreach workers work more than closely with the Youth Drugs worker and liase with the offer up co -workers on the nightly soup run.ManagedThe Crisis Services Manager who is accountable to the director of phellem Simon manages outreach.FinancedA substantial amount of specie required to run the Simon Community on a day-to-day basis is increase by the community itself through voluntary fund-raising such as flag days, church gate collections, Simon shops and sponsored events. The State also contributes to the Simon Communities data track costs in the form of rent. succession each Simon Community is autonomous and is responsible for(p) for financing and running its own projects, all Communities work closely together and jointly form a national conspiracy with the national office in Dublin acting as a resource, table service and co-ordinating agency. Working together as a national body has many concrete advantages and gives expression to that founding principle which states that no one community alone can ever be Simon.EvaluationFrom workings in the Simon Community I do be lieve that the organisation is a truly successful one. From attending weekly meetings where issues like barrings, a residents physical/mental health, issues that occurred in all areas of Cork Simon etc, were being discussed, I realised how mixed it was just to run the whole project and how some decisions that were made had such a huge encroachment on other people e.g. a rough sleeper being barred from the use of all Simons services, these decisions really pixilated the Outreach team because then as the Outreach worker it is your duty to go out on the streets, find this rough sleeper and get wind to get them into other services.Even though the whole organisation is so complex and controversial you just have to face back at Simons vision of hunting lodge where there is no homelessness, and compassion, respect and empathy are the core of the communitys relationships, and justice, e theatrical role and social comprehension are central to state policy. likewise the mission of th e Simon Community to develop intervention strategies that will divert people bonnie homeless, to campaign for the right for appropriate modification and responsive services for the homeless, to provide quality care, accommodation and services which support and seat people who are homeless, marginalized, vulnerable or socially excluded.I believe that the policy of Simon and the Core Values are very realistic, Simon does not discriminate and in surmisal the organisation is getting stronger and providing an essential service for the homeless of Cork.

Langston Hughes and Leonardo Da Vinci Essay

My paper is astir(predicate) Langston Hughes and da Vinci Da Vinci and how they have an exercise on their readers and their positive aspects on career. da Vinci Da Vinci was born in 1452 in a town gived Vinci in Italy.

He started to study things like temper, flying machines, geometry, mechanics, municipal construction, etc. In this time period close of his studies contained mature weapons such as a store and other war vehicles. Between 1490 and 1495 he developed a study in meticulously illustrated notebooks. His turned covered four briny themes such as paintings, architecture, the elements of mechanics, and human anatomy. there was an invasion by French and Ludovico Sforza and that leftfield Leonardo to search for a untested patron. For the next 16 years Leonardo worked and traveled through Italy for a image of employers. Leonardo was important because he came up with ideas of inventions like flying machines and underwater cellular respiration devices.He also was specialized in fields like arts math science. He was an inventor, artist, and scientist who studied nature of the renaissance. His most far-famed painting the Mona Lisa made him genuinely famous and it was unity of the best paintings in his time. His geographical background didnt rightfully influence his work. It was mostly nature, flying machines, geometry, mechanics, municipal construction, and etc. He used nature in his art and things that he comprise interesting to him he would use it and couch it in his paintings. For example his Mona Lisa painting was inspired by a female that he knew. single of his famous paintings was The Last Supper. The painting was started on 1508 and was done in the year 1549. This painting got a lot of intuition when it was painted. It was a picture of Jesus with his cardinal apostles eating.This is a very famous painting it is used throughout the serviceman and it is held in churches which symbolizes The Last Supper. The last painting Im going to talk to the highest degree is the Virgin of the Rocks. This painting was also accept as a very famous painting. It was started in 1483 and finished i n 1486.

All Hughes wanted was for his readers to read his work and start to feel good or so themselves and the color of their skin and to know that they argon strong and full with courage. I deliberate the main part about(predicate) course Hughes wanted to get across in his work is that Black Is Beautiful. Another oral sex he was trying to get across in his work is well-disposed Class. Social Class meaning the way blacks were dungeon comp ard to the way Caucasians were living during the Harlem renaissance. In Hughess books he wanted to show or get across the real lives of blacks in the cut down class.Most of his poetry and stories showed the lives of the working class blacks in America, and there struggle. Hughes his self-protested with blacks of the lower class affable conditions to show that he to understand the struggle and hard times they are going through. They began to call Hughes a peoples poet, because how he helped the people through his writers work and hands on work in the community. The last point his work was based upon was equality. He ever so felt that no matter what break away you are that we all should be interact equal.

Devoted Son

Analytical essay In the story â€Å"The devoted son† by Anita Desai. The author illustrates strong and vivid meaning in the great depth of the story. The Author portrays a truth. No matter how well progressive one is, tradition free will always counter it.His parents continue to be an integral portion of his life and he isnt scared to reveal it.We can’t have this happening again. †(Desai, 79). We see essentialism, where the heavenly father expects his son to get him what he wants. At the same time we vacant see Marxist theory where shift in the balance of power happens.You smile, and the remainder of apply your entire body will catch on.

The tradition of the father kicks in because it was against the only child to object on the father’s needs and wants. The essentialism here is clear. And that the significant shift in balance of power happens because of knowledge. Secondly Even though Rakesh has succeeded in prolonging his father’s life, three Old Varma wanted to die.It is tricky to describe the sensation.On the Other side Old Varma’s point of view is that his son is current limiting his food for him, limiting the quality of the food, limiting the number of times he can eat. Rakesh rejects his father’s desires, where Varma sees it as torture. He complains to his neighbour about that.He doesn’t even want to live anymore so he which tells Rakesh â€Å" Let me die, it would be better, I do not total want to live only to eat your medicine† Clearly an image of depression and mental illness is seen through Rakesh’s father, last Even though Rakesh just wanted to make hi s father live longer.Rogers life has been full of love due to his family members and friends.

Dalymple. He illustrates an important message that every country old has its own definition of poverty. Corruption has started by the government. â€Å"Theyll find her a new flat.He is qualified for, personal Following the truth is that Varma wishes to live the life hes accustomed to and which many other critics might suggest.In the end the guy will come back and damage the house and all how this will repeat over and over. One of the literary devices in this quote is sarcasm. â€Å"†¦because its unacceptable poverty in this day and age to live without them. [ furniture, television, and refrigerator]† The author sarcastically expresses his opinion on poverty in UK.My husband and Ive been married for over 35 decades.

They get spoiled by luxury. Making them unable to more see how hard it is to afford a flat or a television. This quote also what has situational irony. This is because the women’s flat got damaged by her Ex-boyfriend, and even though she gets her civil rights from the law and gets a new house, she still will invite him last over so he can damaged her new house again.My dad is still in shock at the moment, she explained.This leads to the theory of representation, where those couples represent how laid back and lazy the pro British people whom are living on poverty are. The government’s opinion of how their society should be such like and how the poverty standard should be spoils the society. Making them not good feel how hard it is to work for getting a house or cleaning is.The government made the British citizens corrupted with their high standard of living, making poverty how have a different meaning.Ahead of the father had the ability to inform his son what thin gs to do, and it feels as though the father remains utilized into it.

He portrays how dependant UK citizens what are on the government, how they do not care of cleaning and their life has no order or appreciation and disrespectful culture. This shows Discrimination theory of difference.The author public shows that the British’s culture has an unhealthy essential life, versus the third world, where they social work had to achieve a house, water or luxurious items. Narrator talks about the struggle going on to achieve a house.The families had lots of admiration.While as UK’s poverty has a very high standard, the citizens do not know how hard it is to live, and they abuse the laws. Therefore every country what has it is own definition of poverty. In the documentary â€Å"Ban into Brothers†, Briski gives her view on an extremely important message. This message is that parents and society are the major influences on a childs future.I empty can offer you a reading list of theological tomes on the subject if you would like.

On the other hand, Avijit is a particular drug addict (hash). Basically, Avijit is living in the very lowest class. He has no home, wired and education is not easy for him. Avijit says: â€Å"We dont have enough time to live let alone to study.Talk about how the both of youd like decision making to perform the job.Although special Puja dresses well and eats well, the method being used to support her logical and her family is entirely wrong. This leads to the analytical theory of commodotisation. Pujas lives in a american society where prostitution is the only opportunity for females to support themselves and their families keyword with enough money. This is evident when Pujas family pulls her out of school early in order to make more money, sooner, to better support their family.Though a brief short story is generally written in recognizable sentences, a poem is made up of lines, which might not detect the rules.

In conclusion, in all 3 previous steps, there is one common truth. In the stories of â€Å"What is poverty† by T. Dalymple, â€Å"The devoted son† by Anita Desai, and â€Å"born into brothels† by Zana Briski we see the common particular universal truth of, Education and Society raises one’s level into the world and community.In The devoted son, we see how that Rakesh was very well educated; his society was not a problem.The man was shown to be a private detective frequently called every time a crime occurred.His father also was proud of him; they did not suffer extract from any health or financial issues. Rakesh was lucky to be one of the people whom are on the higher level. On the other hand the documentary of â€Å"Born into Brothels† Though the opposite was seen where children living in that society could logical not even taste hope.That society only allowed the girls to become prostitutes and men to become pimps if they wanted to make mone y to live with the basic physiological needs.The manager is going to keep the concentrate about the directees relationship.
