Ashley Alaniz ECON 2302 Armstrong 3 May 2016 CASE STUDY: The Market Failure Analyzation of Alcohol DEMANDERS Alcohol is one of the most popular forms of socializing in America. On average about 66% of Americans say they consume alcohol and with most drinkers admitting to consuming just over four alcoholic drinks per week. According to the Beverage Marketing Corporation, in 2014, alcoholic beverages such as beer, wine, and spirits, make up about 20% of the US beverage market. Beer continues to be Americans favored drink, with wine being second, and liquor being another beloved form of alcohol. The American Beverage Licensees, also known as the ABL is the national association for services such as bars, taverns, pubs, and liquor stores. In an economic study, the ABL estimated that the economic impact of the alcoholic beverage industry in 2014 was more than $245 billion. However, for the past several years the demand for the alcohol market has gradually been declining because consumers are now becoming more health conscientious and choosing better alternatives to drink. Beer has long been the major alcoholic beverage preference compared to wine and distilled spirits and liquor. However, in recent years, beer has been losing its market share to wine and spirits. According to the Market Realist, this trend has negatively impacted beer producers such as Anheuser-Busch and MillerCoors.

Strategy and International Trade Opportunities Free Samples

Questions: 1.What is strategy?2.Discuss about the International Trade Opportunities. Answers: 1.Strategy The video talks about different important terminologies towards the formulation of strategy in different organizations. The organizations should aim for becoming the low cost provider of the service so that there is more number of customers for the company. It is also important to pursue a global strategy that would be competitive and would provide best services to the clients (Eden and Ackermann 2013). The best business solutions should integrate a set of local acquisitions so that these provide better business prospects for the organization (Eden and Ackermann 2013). A company should also strive for giving unrivaled customer services, which implies that the company should aim for providing the best customer service and address all the queries of the customers. The organizations should strive to be the first-mover, which implies that the organizations should incorporate value added services or innovative services to their products or services so that they become the first ones to do so (Verbeke 2013). It is also important to shift the focus to the industrial applications so that they provide more product variety to the clients. These pointers are not considered as strategies that are considered as tactics, which are considered as small components of strategy (Eden and Ackermann 2013). These strategies can also be regarded as objectives and goals, which should be used by the organizations to demonstrate their business acumen. These ideas of strategy are highly relevant in modern day organizations, including Coca Cola. Coca Cola should strive to provide the best services to the customers by including healthy ingredients in their products (Coca-cola.com 2017). The company should incorporate innovative ingredients in their products, such as healthy drink alternatives, which would attract the health conscious customers of the company. It should also strive to provide unique customers service to the organizational clients, preferably in both online and offline mediums (Coca-cola.com 2017). It should answer the queries of the customers, which would improve their business prospects. The company would really benefit from the above strategies. It should integrate local customizations to its products so that they are able to fulfill the preferences of the customers. The increased focus on the local tastes of people would help the company to build customer friendly products that would increase the revenue generation of the organization. It is important to adopt a global strategy for the organization to be successful in the market and to survive the tough competition. The business strategies of IBM Singapore involve a high degree of innovation that would be combined with the artificial intelligence (Ibm.com 2017). The organization aims to put greater emphasis on the transformations in the organization that increase the profitability and the growth (Ibm.com 2017). There is an increased investment in the country so that they can have global audiences and better business prospects (Ibm.com 2017). However, it was not able to attract a large number of local mergers or acquisitions in order to gain better business prospects. It has failed to be the low cost service provider and there are competitors who provide better services to the customers. 2.International Trade Opportunities CAGE is a framework, which is based on the different international and research economics that affects the trade between two countries, which is influenced by different factors (Ghemawat 2013). The application of CAGE framework is dependent on the fact that the managers should identify different attractive locations, which would be based on the costs, raw materials, access to the markets and others (Ghemawat 2013). For example, Cadbury is interested in markets with relatively high purchasing power of the consumers. An international market expansion strategy would be based on the determination of specific resources as well as capabilities of the firm. CAGE defines cultural distance, administrative distance, geographic distance and economic distance (Ghemawat 2012). There is significant cultural difference between the countries, which needs to be considered prior to the international expansion of Cadbury. The values of people of India would be different from that of New Zealand and thi s must be taken into account by the business managers (Ghemawat 2013). They should also focus on the administrative distance, which refers to the present and historical associations between the countries (Ghemawat 2013). The geographic factors take into consideration the physical distance between the two countries or trading partners. The economic distance factor should take into account the fundamental differences in terms of economic criteria such as income, purchasing power of geographic markets and others. Cadbury should consider these factors while venturing into international market expansion. There are considerable amount of difference between the CAGE framework of China and Australia. The Chinese culture focuses on the art of indirect communication while the Australians focus more on the direct communication (Bowe Martin and Manns 2014). The personal space is important for Australians, which is not the case for Chinese people. China is characterized by a command economy, which implies that the central power makes all decisions regarding investment and production (Economy and Levi 2014). On the other hand, the Australian economy is characterized by mixed market economy, which is dominant by the private sector. In China, the distribution of labor is concentrated in primary, secondary and tertiary sectors (Bowe Martin and Manns 2014). In Australia, there is concentration of the labor force in the tertiary sectors such as tourism. The geographic distance between China and Australia is 7,448 kilometers and the air distance is considered as 4,628 miles (Ayson 2012). China is c onsidered as the largest country in terms of population. Australia, on the other hand, is considered as slightly smaller than US and it has 7.62 million square meter of land (Ayson 2012). The economic condition of Australia points on the fact that it has continuous growth as well as different features of low unemployment (Bowe Martin and Manns 2014). It was also characterized by the low public debt and strong financial system. On the other hand, China has been characterized by centrally planned system and it has led to a major role in the global market References Ayson, R., 2012.

Research Proposal on Parental Involvement Essay Example

Research Proposal on Parental Involvement Essay Parental involvement is the participation of parents in the educational process of their children. Parental involvement is a wise decision of the government to improve the quality of education in the country. It is based on a very simple factor: total parental control over their children and constant help if they have problems with studying. When a child goes to school and has certain troubles with some subjects, the teacher often can not devote enough time to him, because classes are quite big and it is impossible to work with children individually. If a trouble occurs, the teacher asks parents to help their child with the problematic questions of a certain subject. Parental involvement is mostly expected to improve the behavior of a child and his attitude towards studying, because very often parents can not help him with education itself. When parents and teachers cooperate, the success of the educational process is supposed to be achieved. Parents control the time of a child, check his homework, make sure he does not miss classes and the teachers only have to share their knowledge with a kid.

info tech essays

info tech essays Topology means how a network is set up. Token Ring topology is one of them. It means that several computers are connected in a ring. When one computer wants to send data to another, it has to catch a free token which gives the permission to send data. As soon as one particular machine gets the token, it has the control over the whole network which means no other computer can send data. Then it puts its destination address and the data on the token, and sends the token to the machine that ¡s next to it. If the next machine is not the destination, it will pass the data on and on until it gets to the address. When the addressed station gets the data, it can not keep the message and release the token. It copies the data, then it sends the message back to the initiator with the acknowledgment to say that it has received the data. After the initiator receives the message and reads the acknowledgment, the free token can be released onto the ring. There are similarities and differences between Token Ring topology and Bus topology. In a Bus topology (Ethernet) all devices are connected to a central cable, called the bus or backbone.(ce.org/networkguide/netstructure/net4.asp) Ring topology is similar to Bus topology in that both networks have multiple access so that the messages will got to every station on the network. However, they are different. First, a Token Ring network has a ring which connects the network instead of a cable. Second, for Ethernet, when computers get messages which do not belong to them, they will not keep them and pass them on. Token Ring topology is different. Every machine on the network will keep passing on the data until it gets to its destination. Third, a computer on a Bus network has to wait for the network to be clear in order to send data packets. A Ring network has a token, so as soon as a machine ca ...

Words That Turn on the Root Vert

Words That Turn on the Root Vert Words That Turn on the Root Vert Words That Turn on the Root Vert By Mark Nichol The Latin verb vertere, meaning â€Å"turn,† is the source of a number of English words that pertain to shifting one’s position from the status quo. The list below defines many of these terms (those with prefixes, and their various grammatical forms); a subsequent post will continue the discussion of additional words in the vertere family: those with suffixes and those with the variant root vers rather than vert. Vert is a rare verb meaning â€Å"turn in some direction,† and those four letters constitute the foundation of most words on this list. When attached to a prefix stemming from the element ad-, it yields the verb avert (from the Latin verb avertere, meaning â€Å"turn away†), which retains the sense of its etymological source (usually in the sense of prevention) and the adjective averse, meaning â€Å"disinclined,† and the noun aversion, describing a disinclination bordering on distaste or disgust. Advert, of the same Latin derivation, means â€Å"turn toward,† though this sense is rare; the word is (in British English) now more common as an abbreviation for the noun advertisement. The verb advertise originally meant â€Å"inform† or â€Å"warn†; eventually, it acquired the connotation of â€Å"call attention to goods for sale,† and the noun became likewise associated with announcements of available products. (In American English, the short form is ad, often misspelled in lay writing as add, perhaps from an erroneous association with addition.) The act of using advertisements, and the industry based on doing so, are called advertising. To â€Å"turn† something or someone so that it or him or her is in agreement with something or someone else (whether a device to be made compatible with another or a person whose beliefs are to be aligned with another’s) is to convert; the concept is called conversion. Converse, meaning â€Å"talk,† is a back-formation of conversation, which originally meant â€Å"living together† and subsequently became a euphemism for sexual intercourse; this sense slightly preceded that pertaining to speaking with someone else. Someone who speaks with others, generally in the context of complimenting the person for skill in doing so, is a conversationalist; a rare variant is conversationist. To divert is to turn away; to present multiple qualities (thus turning away from a single reference point) is to be diverse. An act of turning away is a diversion, and an act of making something more diverse, or the natural process by which this occurs, is diversification. Evert and its adjectival and noun forms, which pertain to turning out or over, are rare, but invert, meaning â€Å"reverse,† is commonly used to describe turning something upside down; the noun is inversion. Subvert has the same general meaning, with the connotation of upending what is considered standard; the adjectival form is subversive, and the noun is subversion. The verb pervert, originally an antonym for the religious sense of convert, came to mean, more broadly, â€Å"corrupt.† The word as a noun, by association, refers to someone with deviant sexual urges; perv (sometimes perve) is a slang truncation of the noun and as a verb pertains to perverted behavior. A corruption of accepted behavior or belief, meanwhile, is called a perversion; the adjectival form for the former sense, meanwhile, is perverse. The verbs extrovert and introvert mean â€Å"turn outward† and â€Å"turn inward,† respectively; each also serves as a noun describing a person with a personality consistent with the respective meaning. The adjectival forms are extroverted (alternatively, extraverted in the context of psychology) and introverted, and the action of turning outward or inward is described, respectively, as extroversion or introversion. Someone who exhibits both personality traits is an ambivert, and that state is called ambiversion. Want to improve your English in five minutes a day?

Provider Roles in Spiritual Care Essay Example | Topics and Well Written Essays - 1250 words

Provider Roles in Spiritual Care - Essay Example From this discussion it is clear that the spiritual dimension of the client is strongly evident during illness, stress, difficulties, and end-life-care when people strongly needed the direction and comfort derived from their spiritual preferences. Faith and religion are essential components of a client’s spiritual dimension and health provider has the responsibility to have self-awareness of one’s spiritual preferences before integrating a non-biased spiritual care.This paper outlines that spiritual care is the most difficult task of a provider, specially the nurses. Most of the nurses lack adequate training for spiritual care giving and may influence the provision of adequate spiritual care. Healthcare providers such as nurses need to have formal education training or graduate programs in pastoral counseling or ministry in order to provide an excellent and competent spiritual care and to refer clients to other spiritual care providers as needed. Organizational team mem bers such as the Baptist Healing Trust aim to further the work of non-profit agencies in providing health services to vulnerable populations in Middle Tennessee. Members of the Baptist Healing Trust heal with love and compassionate care in accordance with the Christian tradition. In addition, staffs of the Baptist Healing Trust have the role of reiterating the importance of meeting health needs, providing human services, and balancing of excellence in skill and great compassion. The Baptist Healing Trust operates as a funding agency and requires partnership with the staff of non-profits to raise the standard of compassionate care. The Baptist Healing Trust also offers retreats, workshops, and consultation for organizational and culture change to continue the delivery of spiritual and health services to the vulnerable and underserved population of Middle Tennessee. The Baptist Healing Trust is the organizational team member of Baptist Hospital in Nashville, Tennessee. The organizatio n believed that true healing comes from deep compassionate care and charitable health care expressed through the preservation of humanity and dignity of each human being as a creation of God (Baptist Healing Trust, 2010, n.p.). The emergence of the healing hospital in Baptist Hospital follows the teachings of Jesus and the Good Samaritan. A hospital institution does not only prevent and cure diseases but also enriched the heart and spiritual needs of client. Spiritual health provider must have a servant’s heart that offers compassionate care, goes beyond the box to meet people’s needs, has commitment to organization’s values, mission, and vision, and expressed care in a continuous chain of light from care giver or provider to every patient, fellow caregiver, and one's

Real and Intellectual Property Law Briefs Case Study

Real and Intellectual Property Law Briefs - Case Study Example Golde made many post operative trips to the medical center for regular check ups. In addition to the normal check ups the doctors at the medical centre conducted research on the cells extracted from Moore's body and hoped to benefit commercially from the results of their research. However, this fact about research was not disclosed to Moore by the Doctors. From the research conducted on Moore's cells, a cell line was developed and got patented by Dr. Golde. Later Golde entered into agreement with the Genetic Institute and was the main beneficiary of the commercial exploits. Moore later sued Dr. Golde and other defendants over the issue. Although the Court discarded Moore's basic claim and ruled that he had no property rights as such or over any money made later on by the defendants by the research conducted and later exploitingg it commercially. It however, said that the defendants were obliged to disclose to Moore the financial angle involved in the cells extracted from Moore's body, so in these circumstances although Moore who had no property rights was free to bring a claim of injuries against the defendants. The decision was given by a bench of Supreme Court of California. Various arguments were forwarded by the counsel for the Plaintiff. The Hon'ble Supreme Court examined them in deatail and reached to a conclusion that the person has no absolute right to the products of his body because they are not unique and further espoused that legislature has formulated laws that stated that forbid patients under some treatment to possess their extracted organs. In this case the plaintiff's spleen was taken out to protec t his life from a life threatening situation but the court ruled out that the patient has an right over the spleen after it has been extracted from his body to save his life and under normal circumstances affected organs or body parts have to be disposed or may be used for research for the advancement of the medical profession. The Court feared that by extending property rights to body parts could spell a doom for the medical profession in general as it is a norm that the affected cells or body parts taken out from patient's body are used for research purposes. Moreover, Moore had given his consent too for the procedure. Although, to some extent it can be said that the consent was not informed as the whole procedure may not have been explained to him verbatim and there were some commercial interests involved. But to that he can only sue his Doctor i.e. Mr. Golde but the other defendants have no liability towards him. Main Issue : The highlight of this judgment was not to extend the status of property to ill human organs as that would have leaded to a plethora of damage suits and loss to the advancement of medical profession. INTELLECTUAL PROPERTY CASE A&M Records, Inc. v. Napster, Inc. Brief Facts : It can be said that this intellectual property law case an landmark case in which the United Court of Appeals decided that

Driverless Cars Are the Present, Not the Future. Essay Example for Free

Driverless Cars Are the Present, Not the Future. Essay With the advancement of technology in today\s world, the driverless car was introduced, and it has been a dominating headline topic within these few years. Many car manufacturers, such as BMW, Volvo, and Audi, have been investing in the development project for the autonomous vehicle. This might prove that driverless car might be the leading car industries in the future. This will lead to a question whether if the driverless car is better than the human-driven car. To have a clearer view of the comparison between them, we can consider these 3 aspects: safety, time and road optimization. Firstly, everyone knows the importance of safety when driving on the road but what makes the driverless car safer than a human-driven car. The driverless car is safer than the human-driven car because of its technology, the driverless car makes use of sensors such as cameras, radar, lasers, ultrasonic sensors, GPS, and mapping technology to determine its position and navigate on the road safely. In contrast, in a car driven by human the drivers make use of their senses, such as eyes, ears and touch to navigate their way on the road. With the increase of travel time, their fatigue level will also increase, this might cause the driver to lose concentration or even fall asleep while driving. Some driver might even consume alcohol before they travel, making it unsafe for other road users as well as themselves. Recent studies of the traffic accident in Singapore 2016 show that causes of human-driven car accident such as failing to keep a proper lookout, failing to have proper control, fai ling to give way to traffic with right of way and changing lane without due care resulted in more than 2500 accident cases. (Singapore Police Force 2016). Whereas for the driverless car in 2016 there is only one case of an accident that happens where the driverless car collided with a lorry at one north which was suspected due to software anomalies in the driverless car (Strait times 2016). Secondly, the time taken to drive from point to point can be quite a hassle, for example, a country like the United State of America where the land is so much bigger than Singapore, traveling from one states to the other would take more than 3 hours or even more. in a car driven by a human, the driver will need to stay focus and concentrate on driving the car to their destination. Whereas for a driverless car the experience will be totally different, the hours of time traveled can be utilized to do more stuff such as reading a newspaper or you can even take a nap while traveling without the need to control your car since the driverless car will take you to your destination. The driverless car will be able to save a lot of our time, it is like adding the extra hours to our hectic life. Lastly, in term of road optimization, there are many traffic lights on the road the human-driven car must stop when they encounter traffic light this will cause traffic congestion, whereas for a country with all driverless car on the road, traffic light is not needed anymore the driverless cars will be able to seamlessly merge to the other lanes easily. Allowing traffic to flow smoothly across intersections. There will be neither time delay nor collision. In conclusion, the driverless car has more advantages in term of safety, time and road optimization as compared to a human-driven car, with the minimal amount of road accident occurs, a large amount of time-saving and the non-delaying road optimization. This futuristic vision is becoming reality with the advancement of technology which will prove that the driverless car will be the leading car industries.

John Brown: Past and Present :: essays research papers

John Brown: Past and Present Host: â€Å"Looking into the crystal ball, I wonder who our guest will be. As the fog lifts from the orb, a picture of a man that has had an enormous impact on our socially accepted views begins to appear. Who is this man?

But his most notable contribution to our country is undoubtedly his involvement in the antislavery movement. The man I am referring to is John Brown. While we talk with him today, we will compare the consequences of past actions with the consequences of today’s actions.

The Importance of the Concept of Cash Flow

Assignment: The importance of the concept of cash-flow for the business finance Definition: Cash flow is the movement of money into or out of a business, an account or an investment. Normally, when the cash inflow is greater than the cash outflow it is a sign of a good financial situation because cash flow is essential for the survival of a business or even to any individual financial condition. If the company can meet its obligations and keep a healthy inflow of cash it has a healthy situation and the management of the company can invest most of its time in developing the company.There are 3 types of cash-flows: Operating cash-flows, which is the money received or spent as a result of a company’s normal business activities. Investment cash-flows, which is the money received or spent through investing activities and thirdly the financing cash-flows, which is the cash received through debt or paid out as debt repayments. Example: Imagine that you run a shoe factory. Having cash is necessary for your business to flow. If you have cash you can pay your suppliers, your employees and yourself on time and so keep the business flow.Therefore if you, as an individual, receive your pay check, you can pay for all your expenses (e. g. housing, food, utilities, insurance, etc). Here we are speaking about operational cash-flow. Another way of creating cash is if you opt for purchasing and selling assets. This is normally a long term issue that can help your business grow and might lead to a net worth increase. This is called investment cash-flow. There are companies that are specialized in this area that manage funds that invest and divest in property.Finally, a third option you have is financing cash-flows. This includes any cash which comes from loans or other types of other debt that allow you to finance your cash flow. It is also used to finance the down payments made of debts. Conclusion: Based on the above, one understands the importance of managing carefully t he cash-flow and also having capacity to meet emergency situations in order to be protected from unexpected circumstances, be it in a business or personally.To be able to run a company in a healthy way it is important to have a good and open relationship with your banks and secure lines of credit for certain times of the year when there is a delay in the cash inflows and also when there is a specific opportunity that requires cash. Companies that manage their cash flow in a positive way have a much stronger possibility of being successful. An example of an unexpected situation, and for which many are not normally prepared, is the sudden downturn in an economy just like what has happened in Portugal in the past three years.The factors which have had the biggest impact in the financial viability of companies are the inflation rate and above all, the restrictions on access to cash (e. g. : loans). If a business is not able to manage its cash-flow carefully and is not capable of setting aside emergency reserves (access to loans), then in a situation like today it will not be able to finance its cash flows and might enter into default. In some cases more than the economic capacity of a company it is its financial situation that might lead to a bankruptcy.We can then say that having cash is crucial for an entity to survive because companies with ample cash on hand can invest the cash back into the business and so generate more cash and profit. An old saying: â€Å"When the going gets tough, Cash is King! † Bibliography: Marques, Manuel de Oliveira, â€Å"A Importancia do Correcto Entendimento do Conceito de Cashflow para a Analise e a Tomada de Decisoes Financeiras†, Estudos de Economia, vol.

Diversity in America Essay

Diversity in america is a trademark of the beauty in our country. Without diversity, America wouldn’t be what it is today. A country that is an obvious reflection of the multiple cultures it contains. The rise and struggle of the African-Americans, The Spanish, Asian, and European immigrants who have all come to the U.S. and contributed to a diverse country. Chinese resturaunts, Soccer, Spanish music, There are so many diverse things that we love. With myself being a part of the Diverse community, it has shown me that being different doesn’t matter. Whether you’re Black, White, or Guynease, anyone can be accepted and become a good friend. In my parents home country of Guyana, the diversity is limited and its shows as they still live as if they are in the 90’s. Being as diverse as the United States has its challenges, races don’t always get along, there is always a feeling of prejudice, and stereotypes put fake labels on people. These challenges can’t always be always be solved it’s up to the people to Be more open minded. Langston Hughes faced a great amount of racism in his days, he had this to say, â€Å"I learned very early in life that our race problem is not really of black against white, and white against black. It’s a problem of people who are not very knowledgeable, or who have small minds, or small spirits.† This quote from hughes tells it all. The benefits from being such a diverse country outweigh the bad, being so diverse means many different people who have different interest and lifestyles. This presents a society where people of all different races are friends and learn from one another. The climate of acceptance in the U.S. is very high, i feel a haitian or cuban immigrant can come to the U.S. and be welcomed and ultimately succeed in this country. This is done by eliminating any racial exceptions and qualifications. Limiting Prejudice is no easy task for any country, there is no law you can put in place to stop it. Ultimately the people have to be educated and told that prejudice is just a factor that exists in your mind to create doubt. They have to know that races are not what many people may perceive. The appreciation for diversity in this country comes from the appreciation of the friends we have made who celebrate their diverse holidays that we too should embrace and the ways of other people and their culture. I happen to already know that our country does appreciate the diversity here and wouldn’t want to see it go and become one-sided. I hold myself to not being prejudice and being accepting, I like to learn of other cultures every once in awhile and be inclusive. All in all, Diversity is an important part of our society and it is a benefit to our country.

Analysis and Discussion of essays

Analysis and Discussion of essays Running head: SUMMARY AND DISCUSSION OF THE FIRST DECADE OF PERSONAL COMPUTING The First Decade of Personal Computing The First Decade of Personal Computing is an interesting account of the technological and financial highs and lows of the computer revolution of the 1970s. Computers of today have evolved from the 1950s room-filling monsters, which required a small army of people to maintain and operate. The 70s computer revolution should be grouped by the following years. From 1970-1974, frustrated engineers accumulated plentiful creative hours inside garages or in other various work centers attempting to turn their computer dreams into reality. In 1975 one of the first and most successful personal computer, Altair 8800, was created and sold. The spring of 1976 Steve Wozniak unveiled the Apple I. Several other computers emerged during this time due to the increased demand and innovation. In 1977 a major paradigm shift changed the way computers were sold. Fueled by the innovative shifts of Apple II, Commodore Pet, and the TRS-80, computers shifted from the kit to the assembled versions. From 1978 until the early 80s the focus shifted to software support. The development of office software applications and video games provided the core technology for computers to become essential for everyday applications. Companies like IBM, APPLE, and Radio Shack profited during the revolution while even more failed. The following key concepts were exhibited through out the article: Ingredients of a new venture, Entrepreneurial Style, and Dynamics of new ventures. All new high-tech ventures have 5 elements, all of which were present in Steve Wozniaks invention of the Apple I. Wozniaks first ingredient, a new product or process or service based on new technology, was the ca ...

Stasis Theory Definition, Use And Key Principles

Stasis Theory Definition, Use And Key Principles Statis Theory For Your Academic Success Some students think that the only goal of a writer is to create simple and readable content, remaining professional and academic. However, you should also provide reliability and accuracy of the mentioned information and the only way to achieve this is to understand the discussed subject. This means that you need to research as much as you can before working on the writing itself. Researching is a great way to learn new data, which is supported by evidence and can greatly improve your critical thinking. This leads us to the most common problem any student has to face: where to find information and how to process it. Luckily, there is a plan, which can help you along the way and it is called stasis theory. In this article, I will tell you what it is about and how to use it effectively in your writing. Definition Stasis theory is a rhetorical approach, which aims to determine the goal of a certain debate issue. It was introduced by Aristotle (or Hermagoras according to other sources) and was used by rhetoricians and philosophers since ancient times. These great minds defined key questions, which were first used in legal cases. Mentioned questions were used in a particular order because the answer on every question depended on the previous one. Stasis theory is very useful for writing essays, conducting research and working as a part of a team. When stasis theory is used, it aims to determine the following elements: Conjecture, i.e. facts; Meaning of the issue (its definition); Importance of the issue (its quality); Plan of actions (so-called policy). Remember, it is crucial to follow the proper order of the theory. However, to simplify the process you can divide every category into subcategories. Below is an example of how you can divide mentioned stages to get the maximum benefits out of the writing process. Fact Did anything happen? What was the cause of the event? Can the event be changed? For example, does climate change exist? What caused it? What can we do about it? Definition Nature of the problem; What sort of a problem it is? What parts make up the problem and how they interlink? For example, is climate change defined solely as global warming or it includes other issues? Quality Does it have a positive or a negative impact? How serious the problem is? What are its consequences and who is the most affected by the issue? What will happen if the problem is solved? For example, are changes in the ecosystem really harmful? Who is the most affected? Policy Should any actions be applied? What groups of people or individuals are involved in the process of solving the problem? What actions should be done? What should happen to resolve the issue? For example, is it necessary to find a solution to climate changes? Who should be involved? Research Stasis theory is a great solution for writers, who are willing to get maximum information on the studied subject. It is a key element of successful work, so you need to understand the theory’s basic principles not depending on the type of assignment you have. Stasis theory acts as a list of the most efficient analytical questions that help in collecting the most recent and relevant information. When you are working on the questions, you need to evaluate multiple sources: literature, interviews, databases, journals, polls and much more. Stasis approach helps not only to get access to the most accurate information on the research but also assists in exploring the issue even before shaping a thesis. For example, you are given a very challenging topic and you need to provide your own opinion and arguments. Before you shape your own ideas, you can apply all the stasis questions and explore the subject. This will help you to decide what side you are on and what your ideas on the matter are. In addition, stasis theory questions help in identifying gaps in your knowledge. If you can’t answer two or more questions, this means that you must conduct deeper research. Teamwork When you are asked to work as a part of a team, stasis approach helps to find common issues by starting a dialogue until the consensus is found. To provide an example, let us again return to the question of global warming and whether it is caused only by the harmful behavior of the planet’s inhabitants. While parts of the team may think that climate change was caused by people, others would disagree. Reaching a certain stasis means finding an idea or term, which everyone could agree with. Even though team members may have different opinion on whether climate changes were caused by people or not, all of them agree that those changes have a negative effect on Earth (fact), it leads to endangering of multiple species (fact) and of course everyone will agree that this problem influences us all (quality). In such a way a stasis will be reached in at least two categories (quality and fact) but they would still disagree on the definition (whether the problem is caused by people or by other issues) and the policy (what actions should be taken to solve the problem). Even if opinions differ, this theory helps to create and hold a dialogue and to write a strong paper. Without such a theory, members of the team would probably drown in arguments and would feel stressed about the assignment. You should remember that working in a team means that you should always use arguments and reach a consensus if members have different opinion. For example, you can make a list of different reasons why people should be blamed for global warming and also provide arguments why they shouldn’t. Let the reader decide whose side to choose. Many field experts name stasis theory a sort of research guideline. Simply by using its standard questions, you will be able to get maximum information on the matter, shape your own opinion and write an assignment, which will be filled with credible data. This theory is also of great use for teams because it helps to find common grounds and solve conflict situations. Remember, stasis theory is all about logic and thorough research of a given issue, so don’t waste your time and get started immediately.

Marketing management Essay Example | Topics and Well Written Essays - 2750 words

Marketing management - Essay Example According to a survey carried out by IBIS world, the profit margins of the industry will reduce by 1.5% over the next 5 years due to mounting competition among the providers. However, this has also led to the falling price of the phones. The company projects that UK mobile phone industry is expected to reach $3 Billion by the end of 2014. Furthermore, the development of new technologies such as, 4G services, the development of smart phones and the new applications, is also driving the industry (Adler, 2010). The UK mobile phone industry is characterised by high rates of market concentration and competition. Some of the key players of the industry are Vodafone, T-mobile, Virgin and O2 among others (Cohen, 2004). The industry will be analysed with the help of Porter’s five forces analysis and on the basis of that, a SWOT report will be prepared. The industry analysis is presented below: - Factor Analysis Resultant Bargaining Power of Buyers The bargaining power of buyers refers to the ability of the buyers to bargain and reduce the price. Reports have shown that the industry is growing at a robust rate and one of the reasons for this colossal growth is the enthusiasm among the buyers. However, due to the presence of a number of providers in the market, the buyers have the tendency to explore the other. This reduces the brand loyalty rate among the consumers. High Bargaining Power of Suppliers The bargaining power of suppliers refers to the ability of the suppliers to bargain and increase the manufacturing cost of the firm (Ferrell, 2006). The suppliers of raw materials for the mobile phone industry in UK is adequate in number and in most of the cases, these companies enter into a treaty with the suppliers which reduces their power to a great extent. Some of the key suppliers are Huawei and ZTE. Moderate Threat of New Entrant The threat of new entrant refers to the threat of a new player entering the industry, thereby increasing the level of competition. To start a telecom business in UK, one needs to go through a series of legal acts and moreover, acquiring spectrum rights is an apprehensive issue. Setting up of a telecom business also requires huge start up cost which often acts as a hindrance. Low Threat of Substitute The threat of substitutes refers to the extent to which substitute products can increase the competition within the industry and act as a potential threat to the firm. The substitutes of a mobile phone are tablets, land phones, palmtops and also, mini laptops to a certain extent, as it serves the core function of facilitating communication. These products are available throughout the country and in almost every outlet. However, due to the portable nature, mobile phone has its own set of customers. Moderate Threat of Competitors The threat of competitors is the level of competition within the industry. In the context of the mobile phone industry of UK, the industry is fiercely competitive due to the presence of a numbe r of players. Some of the established players of this industry are Vodafone, T-mobile, Virgin and O2, among others. High On the basis of the outcome of the industry analysis, following is the set of strengths, weaknesses, opportunities and threats for Blackberry in UK market. The same is illustrated below in SWOT analysis framework. Furthermore, the subsequent section will also prioritise the opportunities by considering certain

Marketing Strategy Based on the Apex City of London Hotel Essay

Marketing Strategy Based on the Apex City of London Hotel - Essay Example Apex should also choose between business and tourist traffic in order to build a competitive edge. The prime location will not yield adequate returns with only a 4-star rating, and the management should plan for an upgrade. London is a major financial, tourist, and historical center. The 2012 Olympic Games and its aftermath will open additional market segments. The city also has a very large number of established and competitive lodging and boarding facilities. Hence, the long term prospects of a new hotel such as Apex cannot succeed without creative and systematic segmentation and accurate targeting as well (Payne, 2002). Apex targets both affluent tourist traffic, as well as middle-level business executives. This is apparent from how the rooms have been appointed, the location chosen, and the conference facilities (Welcome, 2007). This kind of blend is a copy of tactics followed in the past by competing 4-star facilities, but it is not an optimal strategy for Apex to follow. The hotel should either focus on tourist traffic, or specialize as a convention center. It will weaken its branding by trying to do both things (Nijssen and Frambach, 2000). It is true that London has potential revenues from both segments, but since Apex is a late entrant in a mature market, it would do better to specialize in any one of the two segments which it has served during its first year. Generic Strategy Apex could have focused on becoming a luxury hotel for top executives and for celebrity visitors to the city. The prime location chosen makes it suitable for such use. This find of focus generic strategy would have offered the management superior returns on investment (Porter, 1991). However, the hotel has chosen to compete on price. The discounts promotions, deals, and special offers, which Apex offers makes it a place of choice in the prime locality where it is situated. This generic strategy may be difficult to sustain in the long run, and it is probably not required given the enormous traffic through London. The hotel has probably lost significant cash flows through its deep discounts. The forthcoming London Olympics will impact this low-price strategy, as the hotel has established a reputation for discounts in travel circles, which it may not be able to withdraw during peak tourist arrivals (Barger & Kirby, 1995). Overall, the company has not tried to maximize returns on its ne w investment, and has probably

Business environmental and public policy Essay Example | Topics and Well Written Essays - 1000 words

Business environmental and public policy - Essay Example The wrath of industry lobbyists and right wing media was sidelining the politicians of practical nature and who are capable of dealing with the situation as it demands. The narrow margin for Gore in 2000 election is due to his practical ideas on issues like Global Warming. The people who were not at all concerned about the environmental problems and the persons who pander people rather than addressing to their real future needs were in the power. This was the cause of negligence of public safety issues like Global Warming and drawing back in curbing it. As a result the curbing of Global Warming was remained as untouchable. Moreover the campaigners who were against the curbing of Global Warming were publicizing the fact that recently the ice layers in Antarctica did rise in their thickness. Though it was said to be true the warming will be done and the sea level will rise after the extra thick ice was melt. The people who are saying that fact are taking into consideration the details of Antarctica this year. There may be an opposite evidence for their argument if they take the records of thickness of ice for over 10 years of time at the same period of the year. The controversy is that some responsible scientists and politicians like Al Gore were in support of the argument that Global warming is true and the curbing will result in no considerable devastation of economy. But the only politician talking about the controversial issues and the correct measures to be taken was defeated and the right wing media a product of energy-industry lobbyists was making the right thinking politicians a mockery of them in the view of public. They fostered a careful campaign that the curbing of Global Warming will decrease the GDP and thus destroy the economy and so the Americans should not accept to it. But the reality conflicts with that argument. The economy will not be devastated as it was publicized by the media. The growth of GDP may be affected by just 0.2% in a span of 20 years but not as devastating as it was publicized by right wing media. Moreover, the Global Warming is at alarming level that after some time it may become irreversible. By now it was felt by a Science Magazine that the curbing of Global Warming is like eradicating the Small pox from the earth. By this comparison every body can understand that at the stage reached by Global Warming just by negligence due to the lobbying of industry circles against cubing it. One can wonder why the politicians or Industrialists were against the curbing of norms. The reason may be that the norms for curbing the Global Warming will make Industrialists cut their profits and discard some new technology on which they have spent more and there were no substantial returns yet. This may leave them scared as they have to resort to older methods by facing loss in adopted new technology. The Machinery now used might find necessity to be replaced. When this happens generally the heavy industry that makes machines will flourish and there is a chance of curbing the fall in GDP growth which was predicted by the protesters of curbing methods of Global Warming. But it makes some leading industrialists to spend on new machinery and infrastructure, which is difficult to them in their terms of profit. The

Mechanisms of Adsorption of Aormatic Nitrogen Compounds

Mechanisms of Adsorption of Aormatic Nitrogen Compounds MECHANISMS OF ADSORPTION OF AORMATIC NITROGEN COMPOUNDS AND AROMATIC COMPOUNDS ON METAL-ORGANIC FRAMEWORKS (MOFs) by JUN DAI Metal-Organic Frameworks (MOFs) constitute a class of novel porous materials which have attracted significant interest due to their application in separation, storage, catalyst and sensing. Large surface area and porous cavity make MOFs excellent absorbents with huge uptake capacity. In this paper, we studied adsorption mechanisms of adsorption of indole and naphthalene on Basolite F300, Basolite A100 and MIL-100 (Fe) by two complementary spectroscopic methods. Fluorescence spectroscopy and near-UV/Visible diffuse reflectance spectroscopy study demonstrate that naphthalene is quantum confined within the mesoporous cavity in F300. On the other hand, indole is weakly electronically bound to Fe (III) CUS in F300 and forms adsorption complex with F300. Direct spectroscopic proof of adsorption complex is provided by near-UV/Visible spectroscopy and fluorescence spectroscopy. Quenching of ligand-based fluorescence of A100 by indole is suggested and we propose adsorption of indole and napht halene onto A100 via Ï€-Ï€ interaction, spectroscopic proof is provided by fluorescence spectroscopy.   Table of Contents Title Abstract Acknowledgements and Dedication Table of Contents 1 Introduction 1.1 Metal Organic Frameworks (MOFs) 1.2 Clean Fossil Fuels 1.3 Nitrogen Aromatic Compounds in Fossil fuels 1.4 Aromatic Compounds in Fossil Fuels 1.5 Methods of Denitrogenation 1.5.1 Microbial Denitrogenation 1.5.2 Hydrodenigrogenation (HDN) 1.5.3 Adsorptive Denitrogenation (ADN) 1.6 Activation of Open Metal Sites of Metal-Organic Frameworks 1.7 Adsorption of Aromatic Compounds and Aromatic N-heterocyclic Compounds on mesoporous MOFs with CUS: MIL-100 (Fe) and F300 1.8 Adsorption of Aromatic Compounds and Aromatic N-heterocyclic compounds on microporous MOFs without CUS: MIL-53 and A100 1.9 Research Objective 2 Experimental 2.1 Metal Organic Frameworks 2.2 Solvents, Aromatic compounds and N-containing compounds 2.3 Activation and Hydration of Metal-organic frameworks 2.4 Fluorescence Spectroscopy 2.5 Near UV-Vis Diffuse Reflectance Spectroscopy (near UV-Vis DRS) 2.6 Model Fuels 2.7 Solid Mixture of Aromatic and Aromatic N-hetrocyclic compounds with MOFs 2.8 Stoichiometric adsorption complex of F300 and naphthalene in eicosane matrix 2.9 Kinetic adsorption of liquid indole on Basolite F300 (FeBTC) in liquid phase 2.10 Stoichiometric adsorption complexes of indole/naphthalene with MOFs 2.11 UV radiation 3 Results 3.1 Spectroscopic Studies of adsorption of naphthalene and indole on mesoporous F300 and MIL-100 (Fe) with CUS 3.1.1 Solid Mixtures of MOFs and organic aromatic compounds 3.1.2 Fluorescence spectrum of pure naphthalene List of Figures Figure 1: Structure of MIL-100 (Fe) (see as S1 in supplementary) Figure 2: Structure of MIL-53 (Al) (see as S2 in supplementary) Figure 3: Common nitrogen compounds existing in fossil fuels Figure 4: Pathways for the transformation of quinoline Figure 5: Fluorescence spectrum of (A) 0.08 M liquid solution of naphthalene (NAP) in n-heptane, ÃŽ »exc = 280 nm, bandwidth: Exc.

Recently, a novel kind of porous material ‘Metal-Organic Frameworks (MOFs)’ has emerged as potential competitor. MOFs are crystalline hybrid inorganic-organic porous solid formed by chemical metal-linker bounding1. Metal-Organic Frameworks (MOFs) constitute a class of novel porous materials which have attracted significant interest due to their application in separation, storage, catalyst and sensing. The use of MOF as stationary phase in high resolution GC separation of aromatic hydrocarbons has also gained significant attention2. In comparison with adsorption on the MOFs in gas phase which has been well studied and understood, adsorption on the MOFs in liquid phase is much less known. MOFs have extremely large surface area and porous cavity, which make them excellent adsorbents with huge uptake capacity. As a class of coordination compound repeated by metal or metal clusters as SBUs (second building units) and organic linkers, the cavity ranged between that of Zeolite and mesoporous silica3. Regarding the structures, variety of MOFs can display either 2 dimensional or 3 dimensional structures depend on different organic linkers. It is also indicated by J. R. Karra and K. S. Walton that the relation between pore size and guest molecule size plays an essential role in the adsorption4. The MOFs being investigated in this research are mesoporous and microporous MOFs. For mesoporous MOFs the pore size can vary from 2 nm to 50 nm, while for microporous MOFs the pore size is less than 2nm. Pore size can be a key in adsorption on MOFs due to micropore filling mechanism2, which suggests adsorption capacity depends on molecular cross-sectional area rather than minimum diameter. MOFs are structurally stable under ambient environment. It is reported by many authors that MOFs remain stable under increased temperature and under oxygen. In this research, our investigation mos tly focuses on several common MOFS, and their commercial names are Basolite C300, Basolite F300, Basolite A100 and MIL-100 (Fe) (MIL=Materials of Institute Lavoisier). All Basolite C300, Basolite F300 and Basolite A100 are bought commercially, and MIL-100 (Fe) is made with the collaboration of Dr. Jing Li from Rutgers – New Brunswick. Table 1 shows the basic physical information of the MOFs used in this research. Table 1: MOFs used in this research and structure information MOFs/formula Surface area/m2g-1 Pore dimension/Ã… Pore dimension Ref. BET Basolite F300 1300~1600 21.7 3D Sigma-Aldrich,5 Basolite A100 1100~1500 7.37.7 1D Sigma-Aldrich, MIL-100 (Fe) 2200 25, 29 3D 5 MIL-100 family MIL-100(M) (M=Cr, Fe, Al) refers to a family of mesoporous Metal-Organic Frameworks built up from metal clusters and benzene-1, 3, 5-tricarboxylic (BTC) linkers. These MOFs possess large surface area and have recently attracted tremendous attention for applications in adsorption and separation due to the coordinated unsaturated sites (CUS) which can provide chance for Lewis acid-base interaction between guest molecules and metal ions or metal clusters. In Metal-organic frameworks, metal sites (SBUs) are coordinated with organic linkers. Open metal sites (CUS) may be available on these SBUs. CUS are very important in gas storage, separation, sensing, catalysts, and even biological systems6. Considerable amount of research on the adsorption of small molecules have been done recently. Evidence has shown open metal sites have essential influence on adsorption property in MOFs. It is reported that open Cu2+ metal sites in HKUST-1 contribute significantly to the high acetylene storage capa city7. Moreover, MOFs with CUS such as HKUST-1 are used in chromatography separation due to its specific feature to distinguish strongly and weakly electron donating analytes8. In additional, MIL-100 (Fe3+, Cr3+, Al3+) has been shown to have strong preference to adsorb N-heterocyclic compounds (Lewis base) in mixtures910. Hence, open metal sites can be potential Lewis acid sites, the possible interactions between guest molecules and open metal sites will be examined and discussed in this paper. In our research, MIL-100 (Fe) will be used to investigate the adsorption mechanisms between guest molecules such as indole or naphthalene and sorbent MOFs. Besides MIL-100, there is a commercially made MOF named Basolite F300, which has a similar chemical composition. Both Basolite F300 and MIL-100 (Fe) are built up by Iron and BTC linkers. However, due to the poor crystallinity, the actual structure of F300 is still not known at this time. Difference in iron content and carbon content in F300 and MIL-100 (Fe) is shown by D. Amarajothi and his co-workers5. The iron mass content in F300 and MIL-100 (Fe) are respectively 25% and 21%. The carbon mass content in F300 and MIL-100 (Fe) are respectively 32% and 29%. Pore dimension in F300 and MIL-100 (Fe) are respectively 21.7 Ã… and 25/29 Ã…. Structure of MIL-100 (Fe) is shown below: Figure 1: Structure of MIL-100 (Fe) (see as S1 in supplementary) MIL-53 family There are many types of MOFs that undergo hydrolysis, while there are other MOFs that remain stable within water. Water stable MOFs start to showing potential applications in drug delivery and imaging11. Many MOFs containing Al as metal sites and amino acids as organic linkers are stable in aqueous solution, and it is also possible to synthesize them in aqueous environment12. MIL-53(M) (M= metal as Al13, Cr14, Fe15, In16, Sc17) is a common family of microporous MOFs and has excellent water stability. Figure 2: Structure of MIL-53 (Al) (see as S2 in supplementary) The one dimensional pore structure of MIL-53(Al) is built by chains of corner-sharing octahedra aluminum clusters AlO4(OH)2 and anion form of benzene-1,4-dicarboxylic acid (BDC) as organic linkers connecting infinite numbers of metal clusters. MIL-53 (Al) has rhombic channels which have dimension of 7.3 x 7.7 Ã…. A huge Langmuir surface area of 1600 m2/g makes MIL-53 (Al) an efficient adsorbent. MIL-53 (Al) has extraordinary thermal stability up to 773 K. It is believed that the structure of MIL-53 (Al) undergoes a reversible structural change during process of adsorbing/desorbing water molecules, and is described as ‘breathing’13. The so-called ‘breathing’ process interchanges between large-pore (lp) form (Al(OH)[O2C-C6H4-CO2]) and narrow-pore (np) form (Al(OH)[O2C-C6H4-CO2]H2O) 13. The lp form has a dimension of 8.5 x 8.5 Ã… and is obtained when activated upon high temperature and under high vacuum, which takes away excess free BDC acids, oxygen and water trapped in the cavity during synthesis. The lp form is capable of adsorbing water molecules in vapor at room temperature, as a result, the MIL-53 (Al) shifts to its’ np form. As shown in the formula, the np form contains one trapped water molecule every unit or cavity. Hydrogen bonds are found to form between carboxylic groups on the linkers and adsorbed water molecules. Due to this ‘breathing’ feature, applications on selective adsorption of various compounds in gas phase have already gained interest and being reported14. The np form of hydrated MIL-53 (Cr) is able to selectively adsorb CO2 in presence of CH4 in gas phase. Upon adsorption of CO2 but not CH4, MIL-53 (Cr) returns to its lp form with an increased cavity volume of 1522.5 Ã…3 from np volume of 1012.8 Ã…3. In our research, we used Basolite A100 MOF from the BASF, which is commercially available and is equivalent to MIL-53 (Al). Similarly, A100 is build up with AlO4(OH)2 octahedral clusters connecting by BDC linkers, and gives a surface area of 1084 m2/g and pore volume of 0.51 cm3/g as determined by N2 physical-adsorption at 77 K. Additionally, XRD pattern of A100 is proved to resemble that of MIL-53 (Al)18. G. Blanco-Brieva and his co-workers have studied adsorptive removal of aromatic sulfur compounds from model liquid fuels on thermally activated A10019. 1.2 Clean Fossil Fuels Combustion of sulfur and nitrogen containing compounds in fossil fuels will bring adverse effect to public health, environment and economy. It is widely recognized that nitrogen compounds are normally carcinogenic and mutagenic. Separation of heterocyclic compounds from petro-chemical feedstock has become an urgent application leading to clean liquid fossil fuels. Fossil fuel is a primary source of energy on the earth, the intensive use of fossil fuels has raised environmental concerns. Beginning in 2006, the Environmental Protection Agency (EPA) began an ambitious program aiming to reduce the sulfur content of diesel fuels. As of July 11, 2010, the EPA required that the concentration of sulfur content in diesel fuels not exceed 15 ppm20. For certain ultra-clean gasoline, diesel fuels and jet fuels, sulfur level needs to be lower than 1 ppm21. Hydrodesulfurization (HDS) of diesel fuel has become an essential research interest, while the presence of nitrogen compounds in middle-distil late oil inhibits the ultra-deep hydrodesulfurization22232425. In HDS, sulfur compounds are hydrogenated to hydrocarbons and H2S over catalyst such as Zeolites9. However, the nitrogen aromatic compounds in crude oil are found to compete for the active sites on these catalysts to inhibit a deep HDS26,27. This gives rise to the necessity for denitrogenation in fossil fuels. Moreover, the combustion of nitrogen compounds in petroleum leads to the formation of NOx oxides, which is a group of highly reactive and persistent species and contributes directly to acid rain and greenhouse effect. The life time of NOx oxides in atmosphere is 120 years before being removed or destroyed through chemical reactions. The impact of 1 pound of NO ­x on warming the atmosphere is over 300 times that of 1 pound of carbon dioxide. EPA first set standards for NO2 in 1971, setting both a primary standard (to protect health) and a secondary standard (to protect the public welfare) at 0.053 parts per million (53 ppb), averaged annually28. Also the presence of nitrogen aromatic compounds in fossil fuels can lead to poisoning of refining catalyst, which will eventually cause a decrease in yield. Thus, denitrogenation is necessary for deep desulfurization and has drawn significant interest around the world due to the increasingly rigid regulations and fuel specifications in many countries. 1.3 Nitrogen Aromatic Compounds in Fossil fuels Fossil fuels are naturally-formed fuel that contains significant level of heterocyclic aromatic contaminants. There are some representative sulfur aromatic compounds such as benzothiophene (BT) and dibenzothiophene (DBT), representative nitrogen aromatic compounds such as indole and quinoline. Nitrogen aromatic compounds content in crude oil averages around 0.3%. Although the concentration of nitrogen compounds in crude oil is relatively low, the concentration turns out to be higher throughout the petroleum distillation process. Common nitrogen aromatic compounds in fossil fuels are shown in Figure 1.129 and physical properties of nitrogen aromatic compounds investigated in this research is shown in Table 2. Nitrogen aromatic compounds in fossil fuels fall into two classes. One is non-basic nitrogen compounds including indole and pyrrole due to the fact that the extra pair of electrons on N is contributed to the Ï€ electron cloud and is not available for interaction with acids. While the other class is basic nitrogen compounds such as pyridine, quinoline and their derivatives, in which the lone pair of electrons on N is available as an electron donor. Indole is one of the most common nitrogen compounds in fossil fuels, and it has been broadly studied. And we choose indole in our research due to the fact that indole is a weakly basic N-containing compound, which means it has a potential of selective adsorption against aromatic compounds and desorption is possible and reasonably convenient. Figure 3: Common nitrogen compounds existing in fossil fuels Table 2: Physical property of common nitrogen aromatic compounds existing in fossil fuels Compounds Formula Melting Point, ÃÅ'Ã…  C Density, g/cm3 Dipole moment, D Acidity,pKa Maximum diameter, ÃÅ'Ã…  A Indole C8H7N 52~54 1.17 2.11 16.2 6.9 Quinoline C9H7N -15 1.093 0 4.85 7.2 Isoquinoline C9H7N 26~28 1.099 0 5.14 7.2 1.4 Aromatic Compounds in Fossil Fuels Fossil fuels contain significant amount of hydrocarbons, most of them are aromatic compounds and polycyclic aromatic hydrocarbons (PAHs). In this research we choose naphthalene as representative aromatic compounds, and in order to investigate the adsorption mechanism we use fluorescence spectroscopy and UV-Vis diffuse reflectance spectroscopy to investigate electronic interactions upon adsorption onto MOFs. Naphthalene is the most simple and common aromatic compounds in PAHs. And naphthalene is commonly produced in petroleum refining and is then separated from the petroleum. Purification and separation of these aromatic rings is of interest in chemical industry. Naphthalene has a molecular length of 7.2 Ã… (largest diameter determined by ChemDraw 3D) and is non-polar. 1.5 Methods of Denitrogenation Microbial Denitrogenation Microbial process is an alternative pathway for denitrogenation. Microorganisms are known to consume natural organic compounds and convert them into carbons and energy, and they are capable of metabolizing certain molecules including nitrogen compounds from fossil fuels. The degradation of quinoline is well-characterized, and the transformation pathways are elucidated by M. Benedik et al29 (shown in Figure 1. 5). The degradation of isoquinoline is less understood but 1-oxo-1,2-dihydroisoquinoline is suggested as initial oxygenated product30. According to the finding of Claus, G, indole is readily degraded via catechol or transformed directly into tryptophan30, while carbazole is relatively more difficult to be degraded. One possible degradation pathway31 beginning with angular dioxygenation has been proposed by Ouchiyama, N., which finally enters TCA cycle after conversion to catechol or tryptophan32. Mechanisms for the degradation of other nitrogen compounds such as pyridine, quinol ine, acridine and their derivatives are reviewed in detail by J. Kaiser33. Recent research in microbial denitrogenation has revealed a promising future for application in selective removal of nitrogen- and sulfur-containing petroleum. However, as a major mechanism for the removal and metabolism of organic compounds from the environment, its’ characterization of the enzymes involving in the pathways is still under research29. And it has not been widely applied to the industry yet. Figure 4: Pathways for the transformation of quinoline Hydrodenigrogenation (HDN) Hydrodenitrogenation (HDN) is usually used to remove nitrogen compounds in fossil fuels during the refinery process, and Co-Mo catalyst is normally involved in the process. However, the HDS process is accomplished by reacting with hydrogen at high temperature and high pressure. It is energy-intensive, hazardous and costly. Thus, significant amount of researches have been done on HDN in order to reach a goal of being economic and environmentally friendly. Adsorptive Denitrogenation (ADN) Another promising way to selectively remove the nitrogen compounds in fossil fuels is adsorption on a porous material, Activated carbon34353637, Zeolites38, HCL-loaded silica-aluminas39, ion-exchange resins40, meso-silicas41,42, Ti-HMSs43, microporous carbon44, activated aluminas45, Ni-based adsorbents45, and NiMOs46 have been used for ADN. While recently the use of MOF adsorbents has gained significant interest in adsorption and separation of aromatic and heterocyclic compounds in liquid phase due to its’ high capacity, high selectivity, economic importance and most importantly energy saving 47. Moreover, MOFs can even be recycled and effectively reduce the cost. Adsorptive separation via â€Å"adsorptive denitrogenation (AND)† is preferred over industrial catalytic HDN10. Specifically, selective adsorption of N-heterocyclic compounds48 in presence of aromatic and aliphatic hydrocarbons in liquid phase49 is of interest, which is investigated in this research. 1.6 Activation of Open Metal Sites of Metal-Organic Frameworks Available CUS in MOFs is essential for the adsorption of Lewis basic compounds. Thus, to fully utilize the open metal sites in MOFs, activation is needed to evacuate the water molecules which are relatively weakly coordinated on these metals. Because MOFs are strongly adsorptive molecules, humidity can be crucial to the availability of open metal sites in MOFs. Specific treatment is necessary at certain temperature under vacuum in order to activate open metal sites. And protection of the sample against humidity is critical during experiments. Interestingly, it is discovered by K. Schlichte and his colleagues that upon activation the color of HKUST-1 would change from light cyan to dark navy50. This is confirmed by E. Borfecchia and his working group using UV-Vis, a red shift at LMCT edge and appearance of a shoulder in d-d band at around 600 nm in UV-Vis spectrum is observed and explained by the removal of water51. In addition to the activation of MOFs, partial reduction of MIL-100 (Fe) has been reported by H. Leclerc and his group52. Certain metal sites in MOF can be reduced, for example, Fe3+ in MIL-100 (Fe) can be reduced to Fe2+. According to their analysis of oxidation states via IR, outgassing at 423 K for 12 hour will give rise to a greater proportion of Fe2+ sites while minority of Fe3+ sites is reduced. However, outgassing at 523 K will result in that most Fe3+ sites are reduced. Fe3+ sites are more Lewis acidic sites than Fe2+, it is easier for Fe3+ to form coordination bond with nitrogen aromatics, which are good Lewis base. 1.7 Adsorption of Aromatic Compounds and Aromatic N-heterocyclic Compounds on mesoporous MOFs with CUS: MIL-100 (Fe) and F300 Although adsorption of small organic molecules on MOFs both in liquid phase and in vapor, such as toluene, benzene, xylene isomers2, etc., has been well studied in the recent years, to our knowledge the adsorption of fuse-ring aromatic hydrocarbons on MIL-100 in liquid phase has not been reported. M. Maes and his co-workers have reported adsorption of indole from heptane/toluene mixture solution on MIL-100 family9. Thus, mechanism of adsorption of aromatic compounds versus aromatic N-heterocyclic compounds on F300 has not been studied. According to many studies, the formation of complexes in liquid adsorption is usually assumed, but there is a lack of direct spectroscopic evidence. Adsorption of small aromatic ring compounds (benzene and p-xylene molecules) on MIL-101 has been published by K. Yang, et al2. Pore-size filling mechanism is discovered and discussed in this paper, indicating that pore-size and different substrate relates with molecular selectivity of organic compounds. Ho wever, the mechanism is still not understood. Fluorescence spectroscopy is a straightforward method for studying the adsorption mechanism between guest molecules and MOFs. Yet there are rarely papers studying characterization of adsorption of aromatic compounds in liquid or solid system by fluorescence spectroscopy. It is assumed based on fluorescence spectra that Lewis acid-base interaction promotes the adsorption of pyrene on Al2O3 from model fuel using octane as solvent53. While the fluorescence spectra was collected using a model sorbent aluminum chloride in methanol instead of actual Al2O3 in model fuel, spectroscopic characterization of adsorption complexes formed by MOFs and aromatic compounds or aromatic N-heterocyclic compounds by the fluorescence spectroscopy is still unknown to our knowledge. Another useful characterization method is near-UV/visible diffuse reflectance spectroscopy (DRS), which is excellent at detecting the variation or shift in electronic states on adsorption complexes forming by metal sites and guest molecules. The DRS was used to identify the interactions between aromatic amines and MOFs54 but it has not been used to explore the interactions between metal sites of MOFs and guest molecules as aromatic compounds or aromatic N-heterocyclic compounds. Thus, we aim to investigate the adsorption of large aromatic compounds on MOFs using two spectroscopic methods as fluorescence spectroscopy and near-UV/visible diffuse reflectance spectroscopy. 1.8 Adsorption of Aromatic Compounds and Aromatic N-heterocyclic compounds on microporous MOFs without CUS: MIL-53 and A100 M. Maes and his colleagues have studied the adsorption of indole and methyl-substituted indole present in model fuel (heptane/toluene at either 80 vol. %/20 vol. % or 20 vol. %/80 vol. % combination) at initial concentration of 0.15 M on thermally activated MIL-53 (Al)9. The amount of absorbed indole intensively dropped in model fuel with toluene, which indicates a possible competitive adsorption. While no data of adsorption capacity for indole and substituted indole on MIL-53 (Al) in n-alkane solvent was reported, not enough experimental evidence or computational evidence can be used to prove the mechanism of competitive adsorption. Similarly, adsorption of indole, pyridine, pyrrole and quinolone on thermally activated MIL-53 (Al) has been studied in another paper. In this paper n-octane was used as solvent, however, no data for adsorption capacity of indole on MIL-53 (Al) has been reported55. Ï€-Ï€ interactions is suggested to be the major force that introduce the adsorption of indole or quinolone onto activated MIL-53 (Al), but no experimental evidence was given55. At the present time, no direct spectroscopic characterization of chemical bonds between aromatic or hetero-aromatic adsorbate and MIL-53 has yet been reported. Furthermore, adsorption of naphthalene on MOFs has not been reported to our knowledge. To investigate the adsorption mechanisms through fluorescence spectroscopy, it is essential to know the origin of the fluorescence from MOF itselft. It was discussed in a review paper by M. Allendorf, C. Bauer, R. Bhakta et al.56, that there are five modes for generating fluorescence in MOFs: linker-based, framework metal ions (charge transfer between linker and metal), adsorb

Anorexia Nervosa - Includes Bi Essay -- essays research papers fc

Anorexia Nervosa   Ã‚  Ã‚  Ã‚  Ã‚  In America, girls are given the message at a very young age that in order to be happy and successful, they must be thin. Given the value which society places on being thin, it is not surprising that eating disorders are on the increase. Every time you walk into a store, you are surrounded by the images of emaciated models that appear on the covers of fashion magazines. Thousands of teenage girls are starving themselves daily in an effort to attain what the fashion industry considers to be the â€Å"ideal† figure. The average model weighs 23% less than the average woman. Maintaining a weight 20% below your expected body weight fits the criteria for the emotional eating disorder known as anorexia. Most models, according to medical standards, fit into the category of being anorexic (Thompson, Colleen).   Ã‚  Ã‚  Ã‚  Ã‚  Anorexia has been known and recognized by doctors for at least 300 years. Most researchers agree that the number of patients with this life threatening disease is increasing at an alarming rate. The Rice Counseling Center defines anorexia as â€Å"an emotional disorder characterized by an intense fear of becoming obese, lack of self-esteem and distorted body image which results in self-induced starvation†. In accordance with information given by the Counseling Center at the University of Lawson 2 Virginia, the development of this disease generally begins at the age of 11 or 18. Significantly, these ages coincide with new phases of a girl’s life, the commencement and ending of adolescence. Recent estimates suggest that out of every 200 American girls between this age span, one will develop anorexia to some degree. The disease develops over a period of time during which the sufferer changes her eating patterns from normal or near normal to a very restricted diet (S.C.A.R.E.D. Website). This process can take anywhere from months to years. Clinically, an anorexic is diagnosed by having a body weight 20% below the expected body weight of a healthy person at the same age and height of the eating disorder patient. The anorexic often becomes frightened of gaining weight and even of food itself. The patient may feel fat, even though their body weight is well below the normal weight for their height. Some also feel they do not deserve pleasure out of life and will deprive themselves of situations offe... ...ily, friends, and the reasons she may have fallen into a pattern of self-starvation. As a patient learns more about her condition, she is often more willing to try to help herself recover. In treating anorexia nervosa, it is extremely important to remember that immediate success does not guarantee a permanent cure. Sometimes, even after successful hospital treatment and return to normal weight, patients suffer relapses. Follow-up therapy lasting three to five years is recommended if the patient is to be completely cured (Cove, Judy).

Teaching Computer Architecture: How to Introduce the Class

Introduction: How to Teaching is simple. It does not always require creativity to do it right. It is the art of using the right teaching method for the right student personality in the right environment. How much a particular student learns in a course is actually governed partially by that learner's native ability and preceding preparation but also by the consistency of his learning style and the teacher's teaching style. Teachers' teaching plans can exceed the learning process for the students and can improve their learning quality as well if it is well-matched the students' learning styles.The concept of learning styles – which states that different learners have different needs, ways of processing and adapting information, and therefore need to be taught differently so that their learning and achievement are more effective – has been a significant area of investigation in learning theories for over thirty years. In this paper I am designing a teaching plan driven by students learning styles and compatible with the basic two types of learning styles: visual and verbal learning styles.Teaching computer architecture has been examined in many ways like prototyping [1], learning through experience [2] [3] but it hasn't addressed by matching the teaching style with the students learning styles. I chose the first lesson of the computer architecture â€Å"introducing computer architecture course to the students† as an example to prove the enhancement of this approach in teaching computer architecture. The paper is divided to some sections.The first one is setting the base knowledge of the terms that will be used through this paper starting from explaining learning styles then going to clarifying the visual and auditory learning styles. After that, I am going to implement the introduced background in computer architecture context to computer architecture course (ACCESS) at University of Colorado at Colorado Springs. Finally, I will suggest how t o evaluate the applicability and the enhancement of this proposed plan followed by a brief dissection.Page 1 Motivation: First, I was motivated by the importance of computer architecture course. Second, my motivation was also the challenges that I faced in this course thus I didn't satisfactorily understand its concepts. My reason of not fully getting the content was personal; my background knowledge that was required to this course wasn't adequate. Then I asked myself how much have the other students, who have fulfilled the prerequisite, learned? Did they get the essentials of the course?And these questions have formulated my effort presented in this paper here in order to both facilitate their learning and improve their learning quality of this substantial course. Background: A. Learning styles: Learning in an organized educational situation may be thought of as a two-step process encompassing the reception and processing of information. Learning styles can be defined as the prefe rences of an individual in a particular learning situation 4]. It refers to the preferred way of a learner to receive information.Individuals are dissimilar in how they learn. In [5], Richard M. Folder had proposed a model of learning and teaching styles in engineering education that consists of five learning styles dimensions: sensory and intuitive, visual and verbal, inductive and deductive, active and reflective, and finally sequential and global. To match the teaching method with a category of the students learning styles, it changes the way to present information or the way to organize it and sometimes both. B.Visual and Verbal Learners In his model, he had considered the visual and verbal learning styles and had categorized them in the input dimension that deals with the component of the learning process in which information is observed. People receive information in many ways. These ways may be divided into three categories, sometimes mentioned to as modalities: visual ways t hat refers to sights, pictures, diagrams, symbols; auditory ways that use sounds, words; kinesthesia ways such as taste, touch, and smell.Thus, there are visual, verbal, and kinesthesia learners. Visual learners have a reference of seeing: pictures, diagrams, flow charts, time lines, films, or demonstrations and they remember best what they see. They usually like to see the teacher's body language and expressions to better understand the content of lessons, highlight the important points of the lesson with pretty colors, and they Page 2 illustrate the concepts to fully understand and memorize it.If information is simply said to them, they will forget it easily. Auditory learners remember best what they listen to. They acquire a lot out of discussion, learn efficiently by explaining things to ACH other, take the underlying meanings of speech through focusing their listening to tone of voice, read the written materials out loud to absorb and memorize them well, and they prefer verbal clarification to optical demonstration. According to Richard M.Folder, â€Å"most people of college age and older are visual while most college teaching is verbal?the information presented is predominantly auditory (lecturing) or a visual representation of auditory information (words and mathematical symbols written in texts and handouts, on transparencies, or on a chalkboard)†. This present a problem to many learners. C. How we learn? How People Learn: Brain Mind, Experience, and School book [6] has concluded seven primary points of how people learn: 1.Leaning is facilitated when knowledge is structured around major concepts and principles. 2. A learner's prior knowledge is the starting point of effective learning. 3. Awareness and self-monitoring of learning (â€Å"meta-cognition†) are important for acquiring proficiency. 4. Learners' belief about their ability to learn affects their success. 5. Recognizing and accommodating differences in the ways people learn are e ssential. 6. Learning is shaped by the context in which it occurs. . Learning can be strengthened through collaboration.These points also were the foundations of the vision for the future science and engineering learning environment that was anticipated in the new electrical and computer engineering curriculum in 2013 and beyond [7]. In my paper, I am suggesting a plan that is in line with both points number 1 and 5. Implementation: To implement a teaching plan that focuses on visual and verbal learning styles in the computer architecture context, I will be using visual and aural tools to present the content and I will mix using them while I am explaining each concept.The aural tools will be spoken words or written presented text. On the other hand, the visual tools will Page 3 vary between pictures, diagrams and charts. This teaching plan is intended for introducing computer architecture course ACCESS/5200 at University of Colorado at Colorado Spring. The laconic teaching goals for this lesson are: 0 0 0 0 Student defines computer architecture. Student recognizes the role of the technology trends in computer architecture. Student distinguishes between computer architecture and instruction set architecture. Student lists two types of parallelism.And it will be organized as the following: 1. Prerequisite classes. 2. A foreword. 3. Computer architecture definition. 4. Computer architecture intersection. 5. Computer architecture classifications. 6. Why does it matter? 7. Course content. 8. Conclusion. 1 . Prerequisite classes Dependency or process diagram is going to be utilized to show the computer organization prerequisite classes. Computer organization 2. A foreword. Computers have different ways of how we see them. Computer Architecture Personal Mobile devices Desktop Computing Servers Clusters/ warehouseman computers Embedded computersEach of these unlike computers has its own characteristics, requirement, and computing technologies. However, they all have a t least a processor, memory, 1/0 device, and a way to communicate between them. Another way to see computers is this picture. Page 4 Applications System software Hardware SIS SIS in this picture is abbreviation of instruction set architecture, the boundaries between the hardware and the software. 3. Computer architecture definition: So, what is computer architecture? What do the computer architects do? The definition will be driven from the presented pictures above. Computer architects design imputer systems.Hence, it is not equal to designing SIS any more (old definition) SIS is actually a part of computer architecture. The word architecture nowadays covers all three aspects of computer design – instruction set architecture, organization or macrostructure, and hardware [8]. Computer architecture has been defined as designing the organization and hardware of the computer to meet goals and Measurement and Analysis Design Requirements and Castrations functional requirements [8] (figure: 1). 4. Computer architecture intersection: SIS Compiler Logical design Computer architecture is not a stand-alone subject.In order to obtain better computer design, it calls for familiarities with several topics like What do the computer architects do? Figure 1 : compiler, history of computers, and operating systems (figure: 2). A useful suggested tool to visualize the above Computer Architecture prop languages SO Computer history Figure 2: computer architecture interaction http://loving. Host. Sky/attendant/Operating-System-Extended-Machine. HTML Page 5 content would be Venn diagram. 5. Computer architecture classification: The most popular known classification of the computer architecture is Flan's taxonomy.It insiders only the computer processor of the designed computer system. The memory, interconnections, 1/0 devises aren't involved in Flan's taxonomy. The processor receive two kinds of information flow whether data or instruction. According to Flan's taxonomy, both o f the instruction or data streams can be single or multiple. Architecture categories Flan's Taxonomy SITS SIMD MID MISS Another architecture classification is based on the type of parallelism that is exploited in the designed computer system. Tow type of parallelism at the computer application Parallel architecture Data level parallelismTask level parallelism level: data level parallelism and task level parallelism 6. Why does it matter? Architects design architecture for a given technology. Technology parameters quickly change over time. So, it is important to trace the technology trends and plan for it as architects (figure: 3). Parameter Time Page 6 Figure 3: Technology trends Technology: Integrated circuit technology DRAM, Flash Magnetic disk technology Bandwidth and Latency Transistors and Wires Power and Energy: Thermal Design Power (TIP) Dynamic Energy and Power Static power consumption Cost: DRAM pence Microprocessors price Integrated Circuit Cost 7.Course topics: Computer a rchitecture Quantitative approach [8] is a popular book for teaching computer architecture class in many universities, University of Colorado at Colorado Springs as well. So, I am going to adopt the content of this book to introduce the computer architecture topics. Here is a dependency diagram to present the course topics and the book chapters at the same time in relational manner to give the student a glance of how the topics are structured. Also, it can be extended by building up new dependency relations between the chapters as the instructor start to explain them later on the course.This method is to facilitate the learning according to How People Learn book [6] point number one.

Close the talk by summariz ing the information. In conclusion, the computer architecture is to design the organization and the hardware of the computer to meet its functional requirements and intended goals.To do that best, architects asked for taking the technology trends in its consideration to lengthen the life of the designed architects and for taking advantages of parallelism in order to make it scalable and efficient. Measurement and Analysis Indeed, Just one thing needs to change in the teaching plan to engage both visual and verbal learning styles- change the way to present information, provide visual aids in addition to verbal ones. Evaluation: In this section, I am going to suggest an evaluating procedure consist of two parts: satisfaction evaluation and outcome evaluation.First, to assess the satisfaction of this Lana, instructor can look to the learning style for each student in the class using one of the learning styles inventory test that are provided online like: http:// www. Learning-storyline . Com/inventory/questions. PH? Cockiest=y or http:// Then, count the percentage of students that has visual learning style, aural learning style, and other styles. After that, calculate the how much of the students learning styles are covered by this plan design, sum visual and verbal students.Finally, count the parentage of students learning styles that this plan considered to evaluate the degree of satisfaction. Second, in a teaching and learning, the most actual evaluation is that which on the basis of students learning outcomes. So, to measure this plan outcome, instructor can use either way quantitative or qualitative approach like: asking some direct questions to Page 8 students to examine their understanding; print out an assessment examination and give it to each student (figure: 4); asking all the students if they have any questions about the lecture.I recommend the simplest evaluating methodology like the method suggested in [9],†instructors should avoid questions or situations that could make it wizard for students to respond (â€Å"Who is lost? â€Å") or are so generic as to lead to nonresidents (â€Å"Are there any questions? â€Å"). Instead, instructors should pose questions that encourage more specific responses, (e. G. , â€Å"How many of you understand what we are talking about? â€Å"). † Name: ? What is computer architecture? Name: From 1 to 10: How much important is this course?How much you think you can learn this course? As (high – medium – low): How much important is this course? How much you think you can learn this course? Figure 4: example of printed students' assessment Discussion: In USC computer architecture class, while implementing the presented approach, I notice a further unintended advantage. The main goal for this plan was to match the learning style for the visual and verbal learners. But I discovered that it has advantages even if the learning style doesn't match the student like the case o f international students.Indeed, this plan improves the learning for the verbal learners who are taught by a different language from what they are natively speak. There was almost 15% of the students in the ACCESS at USC are international students. This approach can contribute to solve the learning difficulties that the international students face. Assuming that the international students misunderstand 5% to 35% from the spoken language in the lecture, due to the lack of their English vocabularies and synonyms that they are familiar with, the percentage expected to decrease when the instructor uses visual tools in their teaching.Consequently, the progress is accomplished by reducing the misunderstanding percentage of the international students. Observing the visualization tools in this teaching plan, it was suitable for the context that they have been exploited in. One of the efficient teaching visualization tools to computer architecture course is simulators [10], it hasn't used in this suggested plan because it had addressed introducing the course but it still can be used later on the lectures.It helps explaining the main concepts in the course such as CPU [1 1], SIS, or cache memory. Page 9 Even if the computer architecture topics expand, this suggested plan will still be applicable and it will not needs significant changes. Conclusion: In conclusion, the main effort in this paper was a contribution to utilize delivering the computer architecture content to the students. I have used a teaching method that focuses on students' learning style and I have designed a constructible teaching plan.In my suggested designed teaching plan for the first day of computer architecture class, I have chosen two basic learning styles of student, visual and verbal learning styles. Then, I propose a way to evaluate the success of it. In my discussion, I discussed several points; I highlighted a benefit for this approach for international students as well; mentioned visualizati on tools are useful and recommended additional one that haven't used but can be used later in the course, simulations is useful for chemotherapeutics.
