Moreover, because of its huge populace sixe and high extra cash of each Chinese family unit because of its noteworthy financial improvement for as far back as years, China offers extraordinary potential market to numerous global organizations looking for huge number of clients.

Close by with the flood of remote direct interest in China, Chinese portion of exchange on their GDP persistent to build each year as global firms expands the worldwide exchanging exchanges of China to the remainder of the world. Besides, due to China’s huge populace, it has had the option to offer less expensive workers and enormous potential market which are both appealing to outside speculators prompting the improvement of their remote direct ventures for as long as years since the late 1990’s. Without this segment, it is unimaginable for China to accomplish its current state and accomplishments. Since 1999, the GDP development pace of China has been performing stunningly as remote direct speculations settled major monetary markers, explicitly the exchange parity and local utilization, which are crucial in deciding the general execution of a given economy. This just proposes China can offer exceptional yield on speculations to financial specialists in the following coming a long time as China’s GDP development rate persistent to build each year. Because of the exertion of the Chinese government to pull in increasingly remote financial specialists into their market, it has been widely supporting the advancement of its correspondence foundation by giving appropriations to phone organizations. This would before long lift the business exercises everywhere throughout the residential market of China.

The Chinese government is still on the way toward building up its streets and parkways particularly those streets that would interface various areas to significant urban communities. It would even now take a couple of more years before this physical foundation will be completely evolved. References: Bodde, Derk. Presentation.

How to Write the Perfect Physician Assistant School Application Essay

Over at Inside PA Training Paul wrote a wonderful blog post about the common pitfalls that many PA school applicants fall victim to while preparing their PA school essay. CommonPhysician Assistant Essay Pitfalls Clichs Lack of Specificity Weak Conclusion No Theme Boring Introduction This is an excellent listbecause eight years ago while I was applying to PA school Iproved how adhering to each one of these elements was a guaranteed formula for failure. I wrote a blog post a while back about how to get into the PA school of your choice. Part of my recommendation was to throw caution to the wind and apply with your heart and not your mind. This as you know, is easier said than done. Every one of the above pitfalls is what happens when you think too much. The Six Hundred Words (or Less) that Changed my Life I applied to five PA schools in 2001 (prior to The Central Application Service for Physician Assistants (CASPA). First,I used an essay that I thought gave the review committee everything they would need to see that I was a stellar applicant. It showed my strengths, brown nosed a bit, and proved that I had the pedigree to be a wonderful healthcare provider. But, as you will see, it lacked heart, honesty, passion and most of all . . . grit. I received my fourthrejection letter as I was completing my application for the University of Medicine and Dentistry (UMDNJ). I was demoralized. That night I sat down at my computer and composed what would become the 600 words that changed my life forever. I had not read them for over 11 years until this morning. I had never taken the time to go back and see what made the difference. What had made the essay I sent to UMDNJ different from the previous four flops? I was thinking about this list of essay pitfalls this morning and decided to go back and see if I could find my original essays. I was delighted to find all of them, they brought back strong feelings and wonderful memories. I am going to share with you both essays. The one that worked, the one that didn't, and I want you to guess the winner. Avoid the urge to reveal the answer, reading through both essays will help you as you sit down to write your personal statement. When I applied to UMDNJ (Rutgers) I was 0.1 points below the minimum GPA requirement to even consider sending an application. The fact that they opened my application, and offered me an interview was a miracle. Yet, I was admitted just a week after my trip to New Jersey. Where were those other4.0 Ivy leaguers I met during my interview? They were placed on the waiting list. I am not trying to gloat, but I want to point out that the essay may be the single most important thing you do. I believe it is the reason I was accepted to PA school. Two PA School Applications Essays: Why Do You Want To Be a PA-C? PA School Essay # 1 Why Do You Want To Be a Physician Assistant? Every day is a gift to be embraced wholeheartedly. It is our job to fill that day with a hopeful and meaningful purpose. It has been said that the most important thing in life is to live your life for something more important than your life William James. It is deeply rooted in this philosophy that I desire to become a physician assistant (PA). I hope to provide quality healthcare to the underprivileged, an area of medicine, which I have noted to be dramatically underserved. I became involved in health care four years ago to help finance my college education. I worked as a medical records clerk in the University of Washington health clinic. In addition to delivering medical records, I assisted the hospital staff in a variety of activities. I loved working with the staff and admired how well they operated as a team. I desired more direct patient care and in January 1998, when a student position opened in the lab, I jumped at the opportunity. In a few weeks, I was drawing blood, interacting with patients, and helping with a variety of technical procedures. I loved what I was doing. The patients were often uneasy when facing a needle for the first time. I was able to comfort them, help them to smile, and ease their nervous tensions. My job required that I work throughout the various University hospitals. This provided an opportunity to work within a variety of settings, and with people of all ages. Whether it was doing morning rounds in labor and delivery o r working in the campus health clinic, one thing always remained the same; I found great satisfaction in caring for patients and learning of their needs. I felt a career in medicine was truly for me. While working at the clinic I discovered the PA profession. I have always enjoyed the complexities of science and have been fascinated by a career in medicine. In pursuit of this goal, I decided to speak with one of the resident doctors in the clinic. She introduced me to the role of Physician Assistant. After that, I immersed myself in research. I was surprised to learn that many people with whom I worked were Physician Assistants. I met with hospital staff, nurse practitioners, Physician Assistants, and physical therapists. I regularly visited the PA at the clinic and admired his significant level of patient interaction and his ability to work both autonomously and alongside other physicians and nurses. I admired the PA programs flexibility and versatility, which would allow a change of specialties if I desired. I began to focus my attention on becoming a PA. Being an independent thinker, as well as a people oriented individual; I feel that I am well suited, not just for a career i n the medical field, but for a lifetime career as a Physician Assistant. PA School Essay #2 Why Do You Want To Be a Physician Assistant? As a child, every day, I would swing on the swing set in the backyard of my house. I would sit there for hours, without a care in the world simply singing songs and swinging back and forth. On that swing, I felt untouchable. Like a bird in flight, my only cares were that of the sky and the beauty of each adjoining minute. In the swings gentle motion I was overcome with a sense of peace. We wake one day and find that the swing no longer exists. Our backyard has been rebuilt and the ground, which had once supported our youth, has been transcended. We search again for the swing, longing to find a resemblance of that peace. We hope to find it each day, as the product of our life and of our career. A woman smiled at me one day, her name was Margaret. The wrinkles on her face told a story and in her hands there played a motion picture. She sat crouched in a wheelchair; I sat on a stool beside her. I had been working as a phlebotomist in the University Clinic for two years. I was a friend of Margarets because every Wednesday at six she would arrive at the clinic for her routine blood work. Everybody liked Margaret; she used to tell us stories of her childhood and her husband who had given his life to the war. She had grown especially fond of me because I had freckles like her grandson. She used to come alone, but had grown weaker; this was the first time her daughter had accompanied her. Her daughter looked tired and spoke softly, The best vein is in her hand she explained, it doesnt hurt her there. I gently placed my hand on hers, and it was cold. She looked to me and through the cold touch of her hand poured the warmth of her heart. Its about time for dinner dont you think mom, said her daughter. The clock rang six and I agreed. The medicines have been making her sick; she sometimes has troubles keeping her food down. I looked closely at her face; it was thin and drooped to her chest. I realized that Margaret was unable to speak. Margaret, can you make a fist for me? Just like last time. She clenched tightly. I withdrew the needle and collected a small sample of blood. She raised her head and with her frail hand, gently placed it on mine. I looked again to her eyes while placing a bandage on her hand. It was warm now. Time for dinner mom, replied her daughter. I smiled and waved goodbye Margaret I will see you again next week. She raised her head and smiled. Without a word, she made perfect sense. I never saw Margaret again. In the memory of Margaret and every patient who has individually touched my every day, I have regained a piece of the backyard swing that I loved so much as a child. I have been directly involved in health care for four years. Every day has brought great joy. To be a part of a persons day is a wonderful blessing. Certainly, there are many pleasures in life. But, for me, none is greater than that which we find in the healing touch of another. As the eternal motion of the swing, it is in this that I find great peace.

Roberts, Gene, and Hank Klibanoff. The Race Beat: The Press, the Civil Rights Struggle, and the Awakening of a Nation. New York: Knopf, 2006. The Race Beat, written by Gene Roberts and Hank Klibanoff, was about the major impact that the press had on the American People to show the ignorance we’d had to that point in ignoring the horrible segregation our country was showing towards african americans. The events portrayed take place during the civil rights movement. The Race Beat shows the change in style of coverage of the civil rights movement and how the movement itself could take advantage of the press and use it in a much more productive way than before. The author points out in his thesis what he is trying to prove. â€Å"There is little in American society that was not altered by the civil rights movement.There is little in the civil rights movement that was not changed by the news coverage of it. And there is little in the way the news media operate that was not influenced by their coverage of the movement.†(page 7) The authors were very good at proving this thesis to be correct because of their firs t hand experience that is portrayed and the accuracy of the reaction to the new reporting, as it gained national attention. Gene Roberts was one of the young reporters that took on coverage and Hank Klibanoff was one of the editors.

Analysis Of I My Dear And Loving Husband, And Christopher...

Poetry is a beautiful work of literature that expresses ideas and gives words and phrases intense meaning that gets embedded permanently in the mind of the reader. It’s an art mastered by only a handful of talented poets who’s writings stand the test of time. Anne Bradstreet’s poem â€Å"To My Dear and Loving Husband† and Christopher Marlowe’s â€Å"The Passionate Shepherd to His Love† are no exception. These two poems share a common theme of love that uses strong imagery, figurative language, and rhyme to portray the strong love and desire the writer’s poses for their lovers. Love is a feeling that every living thing wants to feel and experience, many have found love like in the poem â€Å"To My Dear and Loving Husband† others are left chasing it like in the poem â€Å"The Passionate Shepherd to His Love†. I have experienced both of these dilemmas and because of my ability to strongly relate to these poems I have chosen to discuss them. Love is something that we as humans cannot help but want and need, it is a natural instinct and desire that we seek to fulfill. In the poem â€Å"To My Dear and Loving Husband† the speaker has clearly found that love. The main theme of this poem appears to be love and more specifically marital love. The poet speaks of her strong and true love towards her husband implying that there is no other wife out there that loves her husband more by stating â€Å"If ever man were loved by wife, then thee;† (Bradstreet 976). As we read further down the writer challenges other women

English Speech Mozart free essay sample

Albert Einstein who said that as an artist, or a musician, Mozart was not a man of this world. His extreme talents enabled him to master a piano piece In half an hour at just 4 years old, write a symphony at five years old and complete writing his first full Opera at the age of 12. Was Mozart a genius or Just a talented and hard rocking person? A scene in Amadeus the play written by Peter Shaffer uncovers Antonio Galleries realization of Mozart Genius.This Is discovered when Sellers sees Mozart own work for the first time without any mistakes. Saltier quotes She had said that these were his original scores. First and only drafts of the music. Yet they looked Like fair copies. They showed no corrections of any kind.

After his failed suicide attempt, he watches his own music diminish into oblivion and Mozart grows more and more popular, Galleries jealousy gets stronger as he decides to make a final attempt to be remembered in the publics eye.As we all know, Saltier cleverly took advantage of Mozart fondness for drink, his financial crisis, and his obsession with leasing his deceased father, and tricked Mozart into working himself to death. The question is why? It is no secret to history that Mozart and Saltier were expert enemies. During their years together in Vienna, Saltier was very much respected lobes. Saltier held succeeding roles as court composer, director of Italian opera, and court conductor. It was very highly unnecessary for Saltier to kill Mozart to put him out of the limelight; Galleries position in the industry gave him all the power he needed.

The Federal Government in the United States

The Federal Government in the United States Federalism and policy development The federal government has some powers over the States in the United States (Dye, 2010). In this regard, it makes choices on a range of aspects.Advertising We will write a custom research paper sample on The Federal Government in the United States specifically for you for only $16.05 $11/page Learn More The idea that the federal government has far-reaching powers over a number of issues raises questions regarding the extent to which the government should interfere with some aspects. Once the federal government decides on issues, in a way, it influences the behavior or the rights of individual citizens. Based on this, it is noticeable that federalism heavily influences policy making in the United States. Using the same line of thinking, the federal government sets the underlying regulations regarding public policy making. It is evident that the federal government decides the procedures or the rules that State governments have to observe regarding some activities. As an illustration, the federal government sets the percentage of revenue that the State governments retain as well as that that they remit. It is clear that the amount of revenue that States collect influence the level of development that States are able to carry out. As such, when the federal government policy puts demands that certain percentages be remitted to the national budget, it influences the developmental agenda of the States. If this holds, then it should also be noted that the State governments are in charge of certain functions at State level. These developmental activities affect the lives of the citizens at the State level. Since the federal government influences the activities, the States engage in, it also affects the lives of citizens. It is thus reasonable to conclude that federal policy activities affect the rights of citizens. Public Policy and Opinion Polls Political processes influence public policy in different ways (Dy e, 2010). Political processes may include elections, campaigns for elections, opinion polls, constitution making, etc. These political processes have varied effects on the policy making process although in unexpected ways (Gray, 2004). Regarding elections, it is noticeable that political parties give clearance to individuals who seek political office (Brown, 2009). As a rule, each political party has its policy agenda.Advertising Looking for research paper on government? Let's see if we can help you!

Concisely, each party has a policy line it seeks to implement upon assuming office. Additionally, upon winning elections, political parties appoint senior office holders in the country. Although, the leaders or office bearers run offices using set procedures, political affiliation may influence the decisions they make. Based on this illustration, it is discernable that the election process may influence policymaking. As presented in the case regarding political processes, public opinion is unstable. Public opinion changes within short spells and may have various degrees of influence on policymaking. As an illustration, it is established from the above point that public policy is a function of elections and the election process. It is noticeable that public opinion heavily influences elections. As an example, when the United States is at war, the public may hold a certain perception regarding the government. Such wars as the one against Vietnam led the public into holding divided views on the role of the government. If the public holds the view that the government is unjustified in engaging in a war, it is likely that the government would be voted out in the subsequent elections. Concisely, it is noticeable that public opinion affects the election process. In turn, election outcomes influence policy making as illustrated above. Reference List Brown, E. (2009).

Business Plan Final Essay Example for Free

Business Plan Final Essay Castle’s Family Restaurant Business Plan: Stage III The purpose of this business plan is to understand the restaurants business and its operations to improve its customer service and its employee relations. The Castle Family Restaurant has eight restaurants that operate under one regional manager that also acts as the Human Resource Manager for the restaurants. The goal is to develop a plan that can decrease the travel time of the regional manager so; that he, Jay Morgan, can save on gas due to high gas prices since each restaurant is located in the northern California area. The objective is to introduce a HRIS application and one vendor that can assist in the developing of the HR department and ease the transitioning of one individual HR manager to multiple employees. There are restaurants with profits in mind and provide the same food and service while the Castle’s Family believes in family, partnerships and developing relationships with one another for a great customer service. Introduction The Castle’s Family Restaurant has eight restaurants in northern California with about 300-340 employees. Most of the employees are part time with about 40% of them full-time. This business plan is to determine strategies that will eliminate the Human Resource position from Jay Morgan, so that he can reduce his travel time to all eight locations and to develop an HR department for the restaurants. In addition, the business plan is to enable Jay Morgan to concentrate on his operation manager duties. The factors that cause many issues to the Castle’s Family restaurant business are having one individual with so many responsibilities. Therefore, hiring an HR manager to schedule, recruit, hire and assist the employees in their needs will help in creating order. In addition, the restaurant must hire an assistant to help in the administration work; it will decrease the amount of  paperwork for the general manager. And each restaurant must have a manager to overseas the employees and the operation of the restaurant. The managers will conduct meetings monthly to provide the sales, revenues and customer services of each restaurant. Managers can communicate through emails, phone calls if they have questions for each other, or have any concerns. A needs assessment must be conducted to determine if an HRIS is needed for the company. In order to have a successful restaurant business every factor must be considered. For example, customer service to the customers is a big factor becau se that is what brings in the revenue. For a restaurant to have a successful business they must have the right food for their customers to enjoy and to assist the customers any way they can. In the last year, there had been some speculation into how the government will help the small restaurants and that the fiscal will prevent any type of savings in when tax time comes around. These HRIS and vendor application that will be stated in this business plan is there to develop and help maintain the restaurant’s H R department and increase growth in the company. We have acquired an HRIS system that will help in developing the HR department to provide easy process for the employees. The Sage HRIS application is an innovative way to ease the transition from traditional HR to a strategic HR. The Sage applications provide variety of options to assist in the HR process. For example, the payroll application should be implemented to help the restaurant establish tax, earnings, and deduction codes to perform critical payroll functions and to modify the system to the restaurant’s needs. This is the first time Castle’s Family Restaurant is developing a HR department, having the right tools to run a department the right way will allow less mistakes to be made; with eight different locations, adding the sage application will help in the transitioning all locations into one. Furthermore, it is critical for a company to have leadership to help establish the employee’s strengths and improve their weaknesses. In addition, the sageâ€⠄¢s time and attendance can help manage the employee’s attendance and work time. The system enables you to collect, analyze, and take control of employee’s attendance and labor data. The  application will help the company in providing perks to employees that always come to work on time. In addition, the performance management application tracks employee’s performance; help identify their critical skills to help the employees in their career development. Furthermore, I have compare and contrast a vendor that would benefit your company. These two vendors provide great services but one match your company’s true values and its missions. The Castle’s Family Restaurant need a vendor that can help in developing long lasting relationship and demonstrates positivity so that individuals can be their best. Furthermore, automation is viable to reduce the need of human errors that can results in more major consequences. Automation errors can occur at any time, the solutions are easy to fix, and automation provide easy data that can be change, delete and edit. The type of HRIS that the Castle Family Restaurant should implement is the Sage application as I have stated before. In order for such application to be developed a vendor must be selected to help in the process. The sage application is a best fit for the company because it has a group of team that can help in assisting in any technical difficulties. When developing new HR department, errors will consist and questions will need to be answered. Therefore, a new training program will need to develop to increase each employee’s skills and performances in the Human Resources Department. The Sage application has the career enhancement training; they have created a system that can help in detecting IT skills, leadership’s skills, etc.; that can benefit your restaurant. The application has an easy to read system. The vendors that I have selected are the ADP and the Rideau Recognition Solutions. The ADP provides all services for domestic international, small or large companies, it does not matter where you operate, and they are there to assist in developing the business. The Rideau Recognition Solutions provide services that inspire employees to succeed to the vendor’s belief. Their expertise is to help their clients build positive relationships with their people to reflect the company’s values and increase customers’ expectations. The Rideau main purpose and their definition of a business are being inspirational and providing inspiration to others. While  ADP is well recognized company that can assist in developing an HR department, and have the tools to performed the job, but because of the deep meaning and relationship that can develop with the Rideau Recognition Solutions and the restaurant being a family company; I believe that the Rideau is the best solution for the Castle’s restaurant. I have recommended that your company, The Castle’s Family Restaurant, to choose the Sage HRIS application and the Rideau Recognition Solution as your vendor. They have the right tools that can establish the restaurant business, and their tools can assist in the development of the HR department. In the restaurant business there will be a lot of risks such as food poising, slip and fall and property damages. Once these types of risks occur this is where the HR department comes in to assist in resolving the situation. This why there should be training when these disadvantages come to light. The sage applications have the proper tools to help decide the professional way to handle such situations. The HRIS application provides professional training to each individual HR employee. While these risks can occur, another problem that cans cause small businesses disadvantage are the fiscal cliff which this year small business operators tax rate has increase by 5 percent. Furthermore, knowing these disadvantages will allow you, the Castle’ Restaurant to prepare yourself as a restaurant. In addition, using these vendors and HRIS system will permit better training; and develop great communication between the HR department and the employees and managers for great customer service. It is important to know the negative factor and a positive factor on owning a small business restaurant and to prepare for any tactics on a professional level. In conclusion, I recommend the Sage as your HRIS application and the Rideau Recognition Solution as your vendor. The Castle’s Family Restaurant has been operating on one person basis, with eight restaurants to oversee. There are many duties to maintain to assure a  smooth business; with such issues that can arise in each restaurant, developing an HR department to oversee these tasks will reduce risks that can occur. I have concluded that the Sage HRIS and Rideau Recognition Solution are the chosen application and vendor for your company to help in the developing your restaurant business. The application and vendor will and can assist you in many different factors and help improve employee communication.

CAPM (Capital Asset Pricing Model) and Its Practical Use Essay

CAPM (Capital Asset Pricing Model) and Its Practical Use - Essay Example It is carried out through a properly designed and professional model that does not require to be completely renewed on a case by case basis. It has, therefore, met the requirements of the Asset Management industry in which the capacity to correctly price securities, and to properly infer the right rate of return. These are used to determine traditional and innovative alternative assets and provide all qualities that can make possible for a portfolio manager to gain an early lead over competitors (Brigham and Houston). The model, from a technical perspective, has been based on the works of Dr Harry Markowitz, a widely renowned professional and researcher who had been able to conduct important studies and researches in the field of diversification and of modern portfolio theory. According to his studies, some fundamental proven hypotheses can be synthesized as follows: Harry Markowitz, Nobel Prizer, investigated the effects of correlation rates and of diversification policies and strat egies. As a result, he found that diversification in this sense, when correctly computed and carried out, can reduce and minimize the risk of a portfolio, together with an improvement of its required rate of returns. In this perspective, a Markowitz Efficient Portfolio has been defined as the portfolio where no added diversification can lower its risk for a given return expectation. In this sense, the ability to properly synthesize the main portfolio requirements is needed in order for a portfolio manager to meet the expectations and to reach the highest expected return. Once this efficient portfolio and its relative asset allocation is reached, no investor can minimize the risk further, and any departure from this allocation is perceived as something that impairs the risk level, and any asset added to the portfolio in this sense increases the risk level of the portfolio. An accurate selection of the most efficient portfolio, hence, can be reached through the analysis of the various possible portfolios of the given securities in the light of their degree of diversification. Dr Harry Markovitz also developed and implemented the so called â€Å"efficient frontier†, which represents the total and integral selection of the most efficient portfolios, analyzed on a risk return perspective. Under this view, the portfolios of assets that compose the efficient frontier are the ones that maximize return levels for certain given amounts of volatility (defined as risk). In this perspective, Harry Markowitz developed a mean Variance model that maximizes returns for given risk levels; the major assumptions of the model are the following: Investors tend to be rational Investors can easily determine the set of efficient portfolios highlighted above and can maximize their returns for a given level of risk There is a single period investment, as compulsory one for the analysis Risk of a portfolio is highly dependent on the variability of returns An investor prefers to in crease the consumption Investors are risk averse by their nature The utility function of investors has a concave shape Major technical aspects of this model make possible to infer some major behavioral characteristic: firstly, investors prefer to retain a portfolio with lower risk, for a given return level. In addition to this, for a given risk (and volatility) level, investors tend to prefer portfolios with higher returns (Markowitz). Investors can be defined as risk averse when their expressed main priority is to minimize risk, and therefore, choose portfolios with lower risk. While, on the other side they are believed to be rational when they prefer asset

Do you think David Hockney's research and theory on the use of Assignment

Do you think David Hockney's research and theory on the use of technology by the artists of the Renaissance period is important for artists today - Assignment Example use people are in continuously eyeball and many students have learnt to do it better than Hockney can within a short time .If it was true that, Old artists were not able to make realistic- drawings, then this means that they were worse at drawing than contemporary art students are and this invalidates Hockneys claim and thus his search for a "better" explanation is left unjustified. Â  Contemporary artists record what they have done and the general methods used to demonstrate how they undertake their business. Dictionary of human form by Ted explains how to make accurate human drawings in broad variety of poses. (Ted, 5-35). Hockney explains that, medieval artists feared being burned as witches for making images with lenses and mirrors, but does not explain how contemporary artists publish information and how they do that. He dismisses past centuries evidence which indicate that old artists did not use optical on the grounds that they actively hided secrets by falsifying evidence. He does not put into consideration dismissing the living artists who work in the way that he claims is impossible. He is similar to a conspiracy theorist that supports their theories because there is no evidence to its negation. Ateliers are not new and they present unbroken chain stretching back to the Renaissance. Books written by pre-20th century painters do not mention the use of optical aids in drawing and painting. These books are still in existence but Hockney did not study them to discover how the Old artists did their work. He selectively choose writing that mention optical devices and went ahead to present the claim as if the rest didnt exist and that, artists lied about the methods they used to avoid being burned as witches. His claim is not convincing because the painters he claim could not paint lived in era where there was no chance of being condemned. Sculpture during the olden days were realistic and lively just the same way drawings and painting were and there were

The Giver Essay   Ã‚  Ã‚  Ã‚  Ã‚  Have you ever felt like starting all over again? Many people would like to have the opportunity to make a new beginning. In the book, The Giver, by Lois Lowry, Jonas is making a new beginning by making an end.   Ã‚  Ã‚  Ã‚  Ã‚  Jonas is making an end by leaving the community. He leaves with Gabriel because he wants to experience true things outside the community. He was very hurt in the community because he could not share his feelings. He wanted to be able to share and experience his feelings with other people. He feels the community does many things that are bad or wrong. Jonas doesn’t seem to like what happens to people when they are released. He wants to change many ways people in the community are treated. Jonas makes a great a choice by leaving the community.   Ã‚  Ã‚  Ã‚  Ã‚  Jonas opens up many opportunities and choices when he leaves the community. â€Å"Jonas sobbed and shouted and pounded the bed with his fist† (Lois Lowry pg 152). Jonas is obviously angry in the situation he is in and with the choices he is given. He wants to have the privilege to make his own choices which he will be able to do outside the community. He can now find peace since he was able to leave and make his own choices . The choices will give Jonas a chance to find a job and other things that are important to his life. Jonas would finally be able to be happy with himself and what he has. It is good for Jonas to be able to have opportunities and choices.   Ã‚  Ã‚  Ã‚  Ã‚  Jonas is making a beginning outside of the community. â€Å"Soon there were many birds along the way, soaring overhead calling† (Lois Lowry pg 172).

Epoxy Resin

Epoxy resin is a type of thermosetting polymer, commercially available in different forms, has a wide range of application in aerospace, coating, electric insulation and marine application due to its outstanding performances, easy handling and low cost [1-5]. Epoxy high inner stress, brittle texture, inferior impact resistance, weak creep resistance and poor moisture resistance, limited its application in other industrial areas [6]. So, the epoxy was mixed with polymers[7], clays, metal [8], carbon nanotube [9], graphene[10], and graphene oxide[11] to overcome its limitations. Graphene oxide (GO) is a graphite derivative that produced through oxidation of graphite using various methods. Graphene oxide is a 2D sheet with oxygen functional at the surface (hydroxyl, carbonyl, and epoxide) and (carboxyl) at its edge [12,13]. Graphene oxide is a promising material as polymer reinforcement, due to its high mechanical properties[14], excellent thermal stability[15], and good insulation properties [16]. Moreover, graphene oxide high surface area, high aspect ratio, excellent sheet flexibility, reactivity sites, and good dispersion in most common solvent favored its use a composites material for polymeric material. The Graphene oxide tends to improve the mechanical properties, thermal stability, insulator, and dielectric properties of the various commercial epoxy resin. However, Graphene oxide sheets tend to aggregate either by Van der Waals force or ?-? stacking interaction, which would decrease the improvement effects of graphene sheets in epoxy matrix [17]. Therefore, graphene oxide was modified either through covalent bonds or by ?-? interaction to reduce these aggregation phenomena and enhanced epoxy properties. For instance, Wan et al improved epoxy tensile strength and modulus by 75% and 15% through mixing epoxy with graphene oxide modified with DGEBA (diglycidyl ether of bisphenol-A) [18].Also, Liu et al enhanced epoxy glass temperature and tensile strength by 26oC and 31% using grafted graphene oxide [5]. Sharmila et al prepared Graphene oxide modified with iron oxide nanoparticles, they epoxy composites shown improvements in the tensile, impact, and fracture strength [19]. Fluorinated polymer is polymer contain carbon-fluorine bonds and they has been applied in many domestic and industrial application due there excellent thermal stability, anti-chemical corrosion, weathering resistance, high dielectric conductivity, and low surface energy [20-22]. However, the high market price of the fluoropolymers and poor miscibility in epoxy resin restricted their applications [23]. Thermal stability, roughness, and corrosion resistance were improved for epoxy resin modified with a fluorinated polymer [24-27]. The fluorine atoms reduced the crosslinking density of the epoxy resin and fluoropolymer, reducing the mechanical properties of the epoxy [28]. The grafting of the fluorinated polymer into carbon base material such as carbon nanotube, fluorinated graphene, and fluorinated graphite may combine the excellent properties of carbon base material and fluorine group's properties. The miscibility was improved with enhancement of the mechanical properties, thermal stability, surface properties, and electric properties. Yang and coworkers grafted fluorinated polymer on reduced graphene oxide coated with dopamine. The modified graphene showed excellent dispersion in the ferroelectric polymer matrix with good high dielectric constant and low dielectric loss [29].Que et al modified epoxy resin (DGEBA) with trifluoromethyl containing polyimide structures. Compared with neat epoxy, they found that the modified epoxy shown better thermal stability with 18 to 55 % char yield at 800 0C, water contact angle (94.9–105.0 °), higher toughness, and lower water absorption (0.47–0.95 %). The tensile shear of modified epoxy was lower than the neat epoxy, the fluorine groups decreased epoxy surface energy which further reduced the adhesion strength compared with unmodified epoxy [7]. In this work, graphene oxide was modified with Hexadecafluoro (1, 10) decanediol through one-step reaction. Modified graphene oxide was mixed with epoxy resin in various loading. Then, the mechanical properties, thermal stability, water contact angle water uptake, and alkaline corrosion resistance were examined for epoxy composites. Results and Discussion:   The surface functionalization of GO was confirmed by FTIR, XRD, XPS, Raman spectroscopy, and TGA. Fig. (1) shows the FTIR spectrum of GO and GOFO. For GO typical peaks were observed at 3390 cm-1 (stretching vibration of C-OH), 1041 cm-1 (stretching vibration of C-O), 1374 cm-1 (deformation vibration of C-OH), 1261 cm-1 and 877 cm-1 (stretching vibration of C-O-C), and 1734cm-1 (stretching vibration of C=O). The peak at 1619 cm-1 is attributed to the skeletal vibration of the graphitic of GO [30]. After reaction with FO new peaks appeared. The peaks at 1178 cm-1 (stretching vibration of C-F) [31], at 2966 cm-1 (bending stretching of C-H), and at 1441 cm-1 (stretching vibration of C-H) from the perfluoro compound. The peak at 1080 cm-1 was related to stretching vibration of ester bond C-O-C. These results indicated that FO was successfully grafted onto GO surface.The XRD patterns of Graphite, GO, and GOFO was shown in Fig. (2) and the interlayer distance was calculated using Bragg equation. Pristine graphite is shown a typical peak at 26.410 with an interlayer spacing of 0.337 nm [32]. This peak shifted to 11.020 (corresponding to an interlayer space of 0.802 nm) after graphite was oxidized to GO, that was due to the formation of oxygen-containing functional groups on a graphite oxide surface and water molecules trapped between the layers [33]. The functionalization of GO with FO shifted the peak from 11.020 to 10.080 (corresponding to an interlayer space of 0.676nm), suggested that GO was modified with FO. Another broad diffraction peak was observed at 22.760, which suggests the formation of few layers of reduced graphite oxide. To further study the structural differences between graphite, GO, and GOFO, the graphitic crystal size was calculated using Sheerer equation and the number of layers was calculated based on crystal size. Graphite had a large crystal size of 21.28nm with 63-64 graphene layers. After oxidation to GO, the crystal size decreased to 10.92nm and the number of layers decreased to 10-11 graphene layers. The crystal size of GOFO was 3.78nm with 5 -6 layers of the modified graphene sheet. In order to study the exfoliation of GOFO into the epoxy matrix, the XRD patterns of EGOFO composites and neat epoxy were investigated as shown in Fig. (3). For neat epoxy, two broads peaks centered at ?70 and ?180 were observed due to the amorphous nature of neat epoxy. All Epoxy composites show the same characteristic diffraction peak as neat epoxy and no diffraction peaks of GOFO at 10.080 and 22.760 were observed [34]. That's confirmed that GOFO was highly exfoliated into the epoxy matrix. Although, the highly exfoliated level of GOFO sheets in the epoxy matrix cannot represent a good dispersion was obtained in the epoxy composites [35]. The thermographic analysis in Fig. (4) represents the thermal stability of GO and GOFO under a nitrogen atmosphere. Graphene oxide shows 8.404% weight loss between 50 0C -100 0C, due to evaporation of residual water trapped between the layers. A significant weight loss of 29.53% was observed between 100 0C – 250 0C, that's due to decomposition of labile oxygen functional groups to H2O, CO, and CO2 [22,10].Compared to GO, GOFO was more stable with 3.48% weight loss was observed between 50 0C -100 0C can be assigned to evaporate of residual water trapped between the layers, which was lower than GO. Between 100 0C – 250 0C, 8.18% weight loss was found due to decomposition of the reaming oxygen functional groups. Then, 12.44% weight loss was observed between 250 0C – 550 0C, that can be assigned to the decomposition of the bond between GO and perfluoro compound. In addition, compared with 48.59% weight loss at 700 0C for GO, GOFO undergoes 20.83% weight loss. The above data can be due to GO, bosses high amount of oxygenated functional groups, while GOFO possesses low oxygenated functional groups due to functionalization by FO. The above results confirmed that GOFO was more stable than GO.Raman spectroscopy was applied to explore the structural variations between GO and GOFO. Generally, the graphitic material shows two characteristic peaks, the G peak (~1575 cm?1) arises from first-order scattering of the E2g photon of sp2 C atoms and the D peak (~1350 cm?1) from a breathing mode of ?-point photons of A1g symmetry. Also, the intensity ratio ID/IG can be used to evaluate the graphitization degree of the graphitic material, the lower value represented a high degree of graphitization [30]. Fig. (5) shows Raman spectrum results of GO and GOFO. The G and D bands of GO were located at 1599.9 and 1357 cm-1 receptivity, as reported in previous reports [30,36,37]. After functionalization with FO, the G band was shifted to a lower wavelength at 1589 cm-1, no obvious changes were observed for the D band. In addition, the ID/IG intensity ratio of GO increases from 0.96 to 1.062 for GOFO. The changes in the intensity ratio imply that GOFO of graphene structure was restored, which can be due to the removal of oxygen functional groups. The GO and GOFO were characterized using X-ray photoelectron spectroscopy (XPS), the results are shown in Fig. (5) and the elemental analysis is tabulated in Table (1). The GO broad spectrum shows two peaks at binding energies around 286.1 eV and 532.4 eV, which were assigned to C1s and O1s, respectively. The atomic composition of graphene oxide was obtained from XPS broad spectrum and revealed the presence of carbon (71.88%) and oxygen (28.12%). In contrast, the GOFO broad spectrum displayed three peaks at binding energies around 286.1 eV, 532.4 eV, and 686 eV, they can be assigned to C1s, O1s, and F1s respectively. The atomic composition of GOFO obtained from the broad spectrum shown the existence of carbon (71.66%), oxygen (27.34%), and fluorine (1%). The carbon-to-oxygen ratio increased from 1.6 for GO to 2.6 for GOFO, due to functionalization with FO. The C1s XPS spectrum of GO and GOFO are shown in Fig. (6). The C1s spectra can be decomposed into four characteristic peaks: C=C/C-C (non-oxygenated carbon, 284.5 eV), C-OH/C-O-C (hydroxyl, epoxy, and 286eV), C=O (carbonyl, 286.8 eV), and COOH (carboxyl, 288.9 eV) [38]. In comparison, the decomposed C1s spectrum of GOFO shows additional peaks at 287.02eV, 290 eV, and 292 eV, assigned to -C-O- (ether bond), C-F (fluorine), and C-F2 (fluorine) respectively[39]. As shown in Fig. (5), compared with XPS C1s spectrum of GO (Fig. (6)), the peak intestines of C-O and C-O-C were significantly decreased, new peaks appeared. The above results indicated the attachment of FO to graphene oxide surfaces via the reaction with hydroxyl groups of FO with C-O groups on the GO surfaces [40]. As shown in the SEM images of EGOFO composites, the GOFO sheets were well dispersed in the epoxy matrix. GOFO nano-sheets were surrounded tightly by epoxy resin, which indicates a good interfacial interaction between GOFO and the epoxy matrix. Such good interfacial bonding improves the stress transfer from the epoxy matrix to the GOFO nano-sheet and thus enhanced the mechanical properties of epoxy composites. However, due to the presence of incompatible fluorine groups on the GOFO, micro-voids can be observed and such voids could enhance crack initiation which leads to decrease the mechanical properties of epoxy composites[41]. SEM analysis of epoxy composites: The SEM images of epoxy and epoxy composites at fracture site after the tensile test are shown in Fig. (7). The images were used to examine the dispersion and the compatibility of GOFO in the epoxy matrix. Fig. (7a,b) shows neat epoxy exhibited relatively smooth surface with a river-like pattern in the fracture direction, confirmed the brittle nature of epoxy [42]. In contrast epoxy composites displayed rougher, fluctuant surfaces with GOFO nano-sheet pulled out of the epoxy matrix Fig. (7 c,e). Also, epoxy composites SEM images shown that GOFO nano-sheets were well dispersed in the epoxy matrix, a well interfacial interaction between the nano-sheets and epoxy composites Fig. (7 d,f). The good interfacial bonds can effectively transfer the stresses from the epoxy matrix to the GOFO nano-sheets and thus enhanced the mechanical properties of epoxy composites [41]. However, several micro-voids can be observed in all epoxy composites that can be due to the presence of fluorine groups. The low compatibility between the epoxy resin and fluorine groups caused the appearances of micro-voids. Cracks can initiate easily in the micro-voids, then spread through epoxy composites reducing epoxy composites strength. Mechanical properties of epoxy composites: Tensile test:The tensile test was conducted to investigate the effects of GOFO on the epoxy resin performance. Fig. (8) shows the stress-strain curves of neat and epoxy composites, and the results were summarized in table (2). The tensile modulus of pure epoxy was 471 MPa and its changes to 486 MPa (increased by 3.2 % with 0.1 wt. %), 507 MPa (increased by 7.6 % with 0.3wt. %), and 530 MPa (increased by 12.52 % with 0.5 wt. %). The highest tensile modulus was 12.52% compared to neat epoxy corresponding to 0.5% GOFO loading. The increase in the tensile modulus was due to the good dispersion and interfacial interaction between the GOFO and epoxy matrix. That's led to the good transfer of stress from the matrix to GOFO sheets. However, the tensile strength decreased by 18.35%, 22.15%, and 20.25% with 0.1 wt. %, 0.3 wt. %, and 0.5 wt. %. GOFO loading. The formation of micro-voids between the GOFO sheets in the epoxy matrix due to incompatibility between GOFO sheet and epoxy system due to the presence of fluorine groups. Fracture test:  Ã‚  The effects of GOFO loading on the fracture properties are shown in Table (2) and the stress-strain curves of fracture analysis were shown in Fig. (9). EGOFO composites shown a battened in the fracture modulus and strength to those of neat epoxy upon different loading. The fracture modulus was 1510MPa for neat epoxy. With 0.1, 0.3, and 0.5 wt. % loading of FO, the fracture modulus increased to 2340 ±17.61 MPa, 2324 ±73.5 MPa, and 2450 ±45 MPa respectively, these were 54.97, 53.84, and 62.85% respectively. However, for fracture strength, it's behaved differently with increasing GOFO concentration. The fracture strength decreased by 13.12% with the addition of 0.1 wt.% GOFO loading and then increased to 13.61% and 16.98% with 0.3 wt.% and 0.5 wt.% GOFO loading respectively. The increase in the fracture modulus and strength can be attributed to improvement in the interfacial interaction between the GOFO and epoxy matrix. That's allowed better load transfer from the epoxy matrix to the GOFO sheets, which increased both fracture modulus and strength. Thermal stability of epoxy composites:The Thermal stability of the GOFO nanocomposites was investigated by TGA as shown in Fig. (10) and Table (3).T10% and T50% are the temperature of sample weight loss reached 10% and 50 % respectively. Tdec is the sample decomposition temperature. All the specimens showed similar thermal degradation behavior with main weight loss between 3500C to 4500C. They exhibited different weight loss during the onset decomposition stages as shown in the enlarged window. The incorporation of GOFO significantly enhanced the thermal stability of epoxy composites in different trends. Epoxy composite 0.3 wt. % GOFO loading has a higher T5%, T50%, and Tdec compared with other epoxy composites. The T5% and T50% increased by ?13 and ?150C respectively based on pure epoxy. The Tdec increased by ?13 with the same loading compared to pure epoxy. According to the literate, there are two factors effects on the thermal stability of polymer composites: the formation of networks via covalent linkages between them and the crosslinking density [43,44]. The existence of the oxygen functional groups at the edge and the surface of the GOFO, can react with the epoxy resin and increased the crosslinking of the composites. The XRD data showed that GOFO doesn't have a uniform crystal shape compared to graphite, that makes the GOFO has a poor thermal conductivity. Therefore, with good dispersion of GOFO, it will act as a barrier and reduce the thermal conductivity of the epoxy composites [44]. Water uptake epoxy composites:The influences of water absorbed by the polymeric material can be significantly reduced by incorporating nano-size fillers into polymers [45,46].The water uptake of neat epoxy and its composites filled with GOFO were shown in Fig. (11). The addition of GOFO nano-fillers significantly decreased the amount of water absorbed by epoxy composites. The water uptake by neat epoxy was 0.432%, which decreased to 0.317% , 0.304% , and 0.308% for epoxy composites with 0.1wt.% , 0.3wt.% , and 0.5 wt.% GOFO loading respectively. this phenomenon implied that the addition of nano-size sheet with high aspect ratio provided tortuous pathways for water molecules to enter the epoxy composites and acted as a barrier water transportation through epoxy composites [47]. Another reason can be due to the hydrophobic nature of fluorine groups on GOFO, which can immobilized water molecules and prevented it from diffusion in epoxy matrix[47]. The hydrophobic behavior of GOFO composites:Fig. (12). Shown the air/water contact angle of pure epoxy and its composites. The measurement was performed at room temperature with three repetitions for each sample. From Fig. (12), the incorporation of GOFO increased the contact angle of all epoxy composites. The contact angle increased from 68.70 o  ± 1.73 for the pure epoxy to 83.53 o  ± 1.13 for 0.1 wt. % GOFO, 98.65 o  ± 2.49 for 0.3 wt. % GOFO, and 89.22 o ± 0.70 for 0.5 wt. % GOFO. The changes in the contact angle indicate that epoxy composites show more hydrophobic effects compared to pure epoxy [48]. The GOFO tends to immigrate to the surface of epoxy, due to the low surface energy of the fluorine atoms. They altered the surface energy and increased the hydrophobicity of the epoxy surface. But, with 0.5 wt. % GOFO loading, the contact angle decreased to 89.22 o ± 0.70, the aggregated GOFO nano-sheet at the surface can slightly reduce the polarity of the surface and increased the effects of the reaming oxygenated function groups of the graphene sheet.

|IPM Project Report | | | | | |Investment Portfolio Creation | |using | |†¦show more content†¦It’s actually a very simple quantitative stock ranking scheme. It uses return on capital and earnings yield as inputs. Return on capital is the metric that shows whether a business is a good one or not. Earnings yield is the metric that shows whether a company is cheap or not. Greenblatt suggests using these measures to identify good but cheap businesses, and buy them. That’s the secret behind the ‘magic formula’. In â€Å"The Little Book That Beats The Market,† Greenblatt calculated hypothetical returns for the 1988-2004 period. The magic formula returned an average 30.8% per year, while the market return was 12.3% and the SP 500 returned an average 12.4%. So this formula beats the market by 18% per year. The two things he looks at are earnings yield, which is how cheap the company is. A simple earnings yield would be the inverse of the P/E ratio or earnings to price. So, in other words, if something earned $2 and it cost you $10 a share, you’d have a 20% earnings yield. It uses a more sophisticated metric than just earnings, than just price. But the concept is the same. It uses EBIT–earnings before interest and taxes and compares that to enterprise value, which is the market value of a company’s stock plus the long-term debt that a company has. That adjusts for companies that haveShow MoreRelatedInvestment Analysis Portfolio Management1583 Words   |  7 PagesHere is the term paper on investment analysis portfolio management from 31st may to 1st august.
