Turning Point in My Life
Seayam, Sidy Instructor: Ludmila Hart ENG 101 ââ¬â 10 09/13/2012 Turning Point in My Life After I finished high school I knew that I had to look forward to my education, and check where I should finish it and think of the future, where I wanted to work and with a good job and if I was going to stay in my country or no. That was the beginning of my life change. June 5th was my last day of high school. I was like everybody happy that school had ended as every year talking with my friends about the exams and how every one did in it and what they expecting about their scores.After that I started to hang out every day with my friends because I didnââ¬â¢t know what I was going to do about college and did not know which major I will choose. I was confused, So I decided to wait for my results then take a decision, days been passing and decided to take Pharmacy or Dentist Major because I love chemistry and biology, but my parents wanted me to retake the high school because I didnââ¬â ¢t get a scholarship, and I refused because I knew thatââ¬â¢s my best and Iââ¬â¢m satisfied with my score.August before my birthday with few days I though about studying overseas and the first countries were Russia and Malaysia, but some of my friends didnââ¬â¢t support me to go to Russia because their friends or siblings were there and couldnââ¬â¢t find jobs with the Russian degree in other countries the opportunities were low in there, So I started to prepare my papers and making researches about Malaysia and itââ¬â¢s universities and found one and sent all my information to that university and they did accept me, one of days my uncle called my from USA to congratulate me graduating from High school and Suggested me to finish my education in the US, I was excited and confused at the same time, and asked my parents about that, they said that I am an adult now and should know my future and they will support me, After that I changed all my plans to US which known the land of opportunities.My first day in the US was November 21th the Thanks Giving day and it wasnââ¬â¢t that cold when I came as I expected it to be, I spent 7 months learning English and taking TOEFL classes to prepare my self for college studies, I started to search for pharmacy and dentist universities, but it was a shock to me from the amounts they wanted, and my parents couldnââ¬â¢t handle that much, so I chosen Computer Science as other interest and found Quincy College to start my future in it then transfer to a four years University. In 3 short months and with a lot of thinking about things I never knew before That was a big turning point in my life and in my future, because I didnââ¬â¢t expect that I come to the US and wasnââ¬â¢t what I was planning for.

Essay Sample on Baby Boomers Health Issues The Current Situation
Essay Sample on Baby Boomers Health Issues The Current Situation The baby boomer generation is an age group of men and women who were born between the years 1946 and 1964. ââ¬Å"Baby boomâ⬠ideally characterizes a time when there was a significant increase in the delivery of children after the Second World War. In addition, this generation characterizes a cultural perspective within the American society. They were born in an ideal environment that promoted the American dream. Current State of Healthcare in the United States In Relation To Baby Boomers Congress approved extensive laws to repair health care in the United States. Healthcare in the United States works in accordance with certain motives. The legal criteria establish the aim of health care as excellent care, not care as a universal amount or economy (Lingaraju Ashburn, 2013, p. 266). Judges concentrate on quality regardless of cost, and the courtââ¬â¢s priority is not an expense. Instead, todayââ¬â¢s court focuses on whether the defendant practitioner meets the criteria of health care or not. The health care framework in the United States currently offers costly but excellent care (Lingaraju Ashburn, 2013, p. 266). The legal system describes the level of care as the health care that a typical practitioner would deliver under similar conditions. Ninety-one percent of doctors confess to sensitively working towards unnecessary care. As a result, the legal care criteria constitute of unnecessary health care. The United States is one of the thirty or more nations with successful single-player worldwide healthcare frameworks. Germany is the single nation with a multiple-payer worldwide care (NYC department for the aging annual plan summary, 2013, p. 127). It is worth mentioning that this system is the same as the one suggested in 1993 by Former President of the United States, Bill Clinton. Today, President Barrack Obama oversees the application of a worldwide health care forum within the United States. President Obamaââ¬â¢s plan, packed as an economic incentive, set up a program for citizens below 65 years not protected by employer health care plans or not eligible for current government agendas (Figueroa et al, p. 367). This is largely because citizen above 65 years of age come from the baby boomers generation. Current Policies and/or Bills or Initiatives Addressing Healthcare in the US Disapproval of the bill strengthened after its approval. As a result, the bill will most possibly endure substantial amendments before it becomes fully functional (Lingaraju Ashburn, 2013, p. 266). The proposal could initiate the formation of a National Health Insurance Exchange (NHIE). The NHIE is a government-operated association operated to sell healthcare plans to people without health care. The impacts of both the issue and the likely solutions in interventional pain management might be superior to those on other subjects (Lingaraju Ashburn, 2013, p. 266). Expenses surfaced as a core component of the national health reform discussion that followed prior to the approval of the Affordable Care Act (ACA) of 2010.à The following is a list of ACA actions projected at cost containment. Superior government inaccuracies and control over health insurer premiums and practices (NYC department for the aging annual plan summary, 2013, p. 128). Rising competition and cost transparency in the sale of insurance rules through health insurance dealings Payment improvements that aim to lower payments for treatments and clinical admissions coming from mistakes or unfortunate quality of care Money for relative effectiveness studies that compare different intercessions and approaches to hinder, diagnose, treat, and observe health conditions (NYC department for the aging annual plan summary, 2013, p. 128). Relocating clinical delivery frameworks to be patient-based and advance the coordination and quality of care The new health care law approved by Congress does not tackle offense reform. Rather, it lowers doctor compensation and raises penalty-oriented expenses and control regulations. Doctors have to deal with the new and the decisive burden of this legislation. This is because of the doctorsââ¬â¢ entanglement between health care and criteria. This entanglement strictly calls for excellence irrespective of cost and penalty-based federal orders challenging economic health care irrespective of authorized care standards (Figueroa et al, 2013, p. 369). Congress amended and fixed the universal health care program bill on a number of events. The president did not approve this bill until March 2010 and will not be fully effective until 2014. How Baby Boomer Healthcare Currently Influences the Nursing Practice The baby boomer generation slowly gets old as chronicity rises together with the complication of care. Currently, the United States is in dire need of additional nurse practitioners, doctor assistants, and primary caregivers (Lingaraju Ashburn, 2013, p. 269). The nursing deficiency in the United States may deepen as baby boomers get older, and the necessity for healthcare rises. Intensifying the issue is the fact that nursing schools across the nation struggle to grow registration levels to meet the increasing demand for nursing expertise (NYC department for the aging annual plan summary, 2013, p. 131). Conclusion Older patients who undergo prolonged pain because of soreness or other conditions see chiropractors, acupuncturists and bodywork therapists. These medical workers pinpoint sources of pain and lower it by improving blood flow, exercising stiffness in the muscles, and improving body positions. The American Association of Colleges of Nursing (AACN) prioritizes the deficiency of enrolled nurses. Learning institutions, lawmakers, affiliated organizations, and the media currently work with the agency to make the nation realize this clinical crisis (NYC department for the aging annual plan summary, 2013, p. 131). AACN currently works on implementing laws, pinpointing approaches, and forming alliances to tackle the nursing shortage issue.

What Is Citation Order (Authorââ¬Date Referencing) - Get Proofed!
What Is Citation Order (Authorââ¬âDate Referencing) - Get Proofed! What Is Citation Order? Did you know that you can reference more than one source at once? This is a skill that every student should have. In this post, then, weââ¬â¢re looking at the rules for citing multiple sources and how citation order works in author-date referencing. When to Cite Multiple Sources Most of the time, one source is enough for a citation. For example, if you simply want to show where an author has discussed something, all you need to do is cite the relevant text: He argues that sport can be understood in economic terms (Lee, 2015). But if you want to show that someone has discussed something in more than one text, you could cite multiple sources by the same author. Likewise, to show that several people have discussed the same thing in various places, you could cite multiple sources by different authors. We will explain how this works below. However, keep in mind that you should only include multiple sources in a single citation if they support the same point. If youââ¬â¢re making more than one point in a single passage of text, you should give a separate citation each time. Citing Multiple Sources by One Author To cite more than one source by a single author, all you need to do is list the years of publication in chronological order. For example: He repeatedly argues that sport can be understood in economic terms (Lee, 1999, 2008, 2015). This shows Lee has made the same argument in at least three places. Each source would then be listed with full publication details in the reference list. One slight exception to this is MLA referencing, where citations do not include a year of publication. If youââ¬â¢re citing more than one source by the same author, youââ¬â¢ll therefore need to give a shortened version of the title for each one. Multiple Authors (Citation Order) Things get a bit more complicated when citing multiple sources by different authors. One common way of doing this (e.g., the style recommended in APA referencing) is to list sources alphabetically by author surname with a semicolon between each one: Other studies on the same subject reject this possibility (Acaster et al., 2002; Herring, 1986; Robins James, 1992; Widdicombe, 2015). However, some versions of authorââ¬âdate referencing recommend a citation order based on date of publication. For example: Other studies on the same subject reject this possibility (Herring, 1986; Robins James, 1992; Acaster et al., 2002; Widdicombe, 2015). This makes it essential to check your style guide for advice on citation order. If you cannot find specific instructions, though, simply pick one approach and apply it consistently throughout your document.

International Business Essay Example | Topics and Well Written Essays - 1500 words - 2
International Business - Essay Example After achieving huge success level in domestic market leading companies wish to do business practices across the domestic border in order to maximize profit, its market share, core competency and goodwill. These are all tangible and intangible assets of a company. The company chooses internationalization process in order to take the advantages of advanced technology, potential marketplace and favorable economical factors of international market. The internationalization process and the reason of adopting the process can be identified by several business models. Demand and supply led drivers will help to identify the advantages of customer and supplier relationship management for the international market orientation and the difference of these two drivers will help to identify the impacts on business practices for a company. Followed by this the Eclectic theory of internationalization will help to analyze the different categorized advantages that will help international business pract ices. Next the Uppsala model will help to find the business activities of a company in a foreign market. Last but not the least the product life cycle tool will help the company to develop their product internationally considering different aspects of product life cycle. The objective of the study is to find the reason for internationalization of a company and evaluation of several international business tools. Demand and Supply Led Drivers In order to adopting international business process companies need to understand about the demand led drivers and supply led drivers. The basic purpose to reinforce this demand and supply drivers is the gaining knowledge of companies about the demand chain management and supply chain management in international market. The difference of demand led driver and the supply led driver in specific international market is based on importance. The supply led drivers is the degree that focus on consumers and this driver gives importance on efficiency of s ervice. Here the company management consider about cost-led and supreme level of customer service. The risk of this supply-led driver is that the target customers may be aggregated. Therefore the link between customer and supplier relationship management may be hampered. Demand led drivers hold the broader vision of relationship management. This driver integrates both of the customer and supplier relationship management. The need of demand led driver is to allocate required resources for thy international operation (Porter, 2011, p.115). It is kind of a push strategy which influences both the customer and suppliers. Supply led driver is more of a pull business aspect. It may affect the target customers different brand loyalty and orientation. Eclectic Theory Eclectic theory of internationalization is the economics theory based on the theory of transaction costs. The idea behind the application of eclectic theory in internationalization process is to understand the economic approache s in international competitive business market. The fundamental forms of international market such as Licensing, FDI, and Export can be distinguished by this theory (Cantwell and Narula, 2012, p.71). Before entering in international market the three categories of advantages in internationalization process of this theory such as ownership advantages, internationalization advantages and location advantages need to be identified by the company. If the company has ownership advantages such as knowledge about the international target market, employeesââ¬â¢ international language skill, appropriate products, information about import permission and huge contacts can help the company to do the Licensing in

Do You Know What It Means to Lose New Orleans by Anne Rice Essay
Do You Know What It Means to Lose New Orleans by Anne Rice - Essay Example Her thesis was also based on the irritating utterances made by some eminent people and journalists concerning the flood crises in the area. Rice has relied on her thesis in writing the whole essay. The entire essay revolves around the author main thesis. The thesis is very relevant and acceptable to the situation which occurred in the New Orleans during the flood crises. To start with, the city is very important to its residents and the entire United States of America economy. It accommodates a very unique subculture in America known as Africa-America. On the other hand, the city has its own history ranging from as early as in 1800s and United States of America history is not complete without the inclusion of New Orleans city. Additionally, the city offers employment and accommodations for thousands of people who reside in the area. There are also very many churches, universities and other infrastructures which are extremely imperative for the development of America and the entire wo rld. Compared to other states in United States of America, New Orleans is extremely peaceful and accommodates a substantial number of black Americas. The city is also very beneficial to United States of America economy as its unique music and essays attract both local and foreign tourists in the country. It is also only in New Orleans where there exist peaceful societies where people maintain their family institutions, love each other as well as caring for other people welfare. Therefore, according to Rice, New Orleans ought to be given appropriate attention in the times of crises just like any other state in America (Anne 1). Does the other have good support for her thesis? Rice has adequate and concrete support for her thesis. In the initial stage of explaining her thesis, Rice provides a history of New Orleans city and its important to America. He quoted others writers who had come together to writes essays on the important of New Orleans to American in early 1840s. According to Rice, many people who reside in the states declines to go to other states because of the favorable condition in the state. Rice also explains the important of the city to the United States of America as a country. He quotes some of the most crucial structures which exist in the city and their relevant to America and the world at large. According to her observations, universities such as Xavier and Dillard University are very crucial to black America. On the other hand, in her essay, Rice talks about the state harmony and attractive music which is exceptionally appropriate in attracting local and international tourist thus leading to economic development in the country. Does the author have strong argument or weakness? What makes it strong or weak? Rice has a very strong argument in her essay. To justify her argument, the authors has started by analyzing the history of New Orleans in explaining the important of the city to its residents and to the entire Americans. She refers to old days writers who have written about the important of the city to America. On the other hand, the author talks about the reality in New Orleans. The city is occupied by both whites and blacks in America. The harmony of the country is brought about by the caring status of the cityââ¬â¢s residents. She provided an example in which residence of New Orleans offered adequate assistance to flood victims. As a matter of fact, the area is occupied by middle class and

Why Star Topology is Best
Why Star Topology is Best 1.0 SYNOPSIS This study focused on a star network topology. A star network is a local area network in which all devices are directly linked to a central point called a hub. Star topology looks like a star but not exactly a star. The findings from the study revealed that in star topology every computer is connected to a central node called a hub or a switch. A hub is a device where the entire linking standards come together. The data that is transmitted between the network nodes passes across the central hub. The project further goes on to explain the advantages, disadvantages and usage of star network topology. The centralized nature of a star network provides ease while also achieving isolation of each device in the network. However, the disadvantage of a star topology is that the network transmission is largely reliant on the central hub. If the central hub falls short then the whole network is out of action. Star networks are one of the most common computer network topologies that are used in homes and offices. In a Star Network Topology it is possible to have all the important data backups on the hub in a private folder and this way if the computer fails you can still use your data using the next computer in the network and accessing the backup files on the hub. It has come to realization that this type of network offers more privacy than any other network. 2.0 INTRODUCTION The main objective of this project is to discuss the advantages, disadvantages and usage of star network topology. A topology is a physical structure of a network. Star topology is a network structure comprising a central node to which all other devices attached directly and through which all other devices intercommunicate (http://www.yourdictionary.com/telecom/star-topology). The hub, leaf nodes and the transmission lines between them form a graph with the topology of a star. Star is one of the most and oldest common topology in the local area network. The design of star topology comes from telecommunication system. In telephone system all telephone calls are managed by the central switching station. Just like in star topology each workstation of the network is connected to a central node, which is known as a hub. Hub is a device where the whole linking mediums come together. It is responsible of running all activities of the network. It also acts as a repeater for the data flow. Generally when build a network using two or more computers, you need a hub. It is possible to connect two computers to each other directly without the need of a hub but when adding a third computer in the network, we need a hub to allow a proper data communication within the network. In a Star Network the whole network is reliant on the hub. (http://www.buzzle.com/editorials/2-6-2005-65413.asp) Devices such as file server, workstation and peripheral are all linked to a hub. All the data passes through the hub. When a packet comes to the hub it moves that packet to all the nodes linked through the hub but only one node at a time successfully transmits it. Data on a star network exceeds through the hub before continuing to its target. Different types of cables are used to link computers such as twisted pair, coaxial cable and fiber optics. The most common cable media in use for star topologies is unshielded or shielded twisted pair copper cabling. One end of the cable is plugged in local area network card while the other side is connected with the hub. Due to the centralization in star topology it is easy to monitor and handle the network making it more advantageous. Since the whole network is reliant on the hub, if the whole network is not working then there could be a problem with the hub. The hub makes it easy to troubleshoot by offering a single point for error connection at the same time the reliance is also very high on that single point. The central function is cost effective and easier to maintain. Star topology also has some draw backs. If the hub encounters a problem then the whole network falls short. In a Star Network Topology it is possible to have all the important data backups on the hub in a private folder and this way if the computer fails you can still use your data using the next computer in the network and accessing the backup files on the hub. 3.0 BACKGROUND STUDY In this section the researcher has clarified and explained in details some of the advantages, disadvantages and usage of star topology. These three concepts are the main core of this project. 3.1 ADVANTAGES OF STAR NETWORK 3.1.1 Isolation of devices: each device is isolated by the link that connects it to the hub. By so doing it makes the isolation of the individual devices simple. This isolation nature also prevents any non centralized failure from affecting the network. In a star network, a cable failure will isolate the workstation that it links to the central computer, but only that workstation will be isolated. All the other workstations will continue to function normally, except that they will not be able to communicate with the isolated workstation. http://en.wikipedia.org/wiki/Star_network) 3.1.2 Simplicity: The topology is easy to understand, establish, and navigate. The simple topology obviates the need for complex routing or message passing protocols. As noted earlier, the isolation and centralization simplifies fault detection, as each link or device can be probed individually .Due to its centralized nature, the topology offers simplicity of operation. (http://en.wikipedia.org/wiki/Star_network) 3.1.3 If any cable is not working then the whole network will not be affected: in a star topology, each network device has a home run of cabling back to a network hub, giving each device a separate connection to the network. If there is a problem with a cable, it will generally not affect the rest of the network. The most common cable media in use for star topologies is unshielded twisted pair copper cabling. If small numbers of devices are utilized in this topology the data rate will be high. It is best for short distance ( http://fallsconnect.com/topology.htm#a) 3.1.4 You can easily add new computers or devices to the network without interrupting other nodes: The star network topology works well when computers are at scattered points. It is easy to add or remove computers. New devices or nodes can easily be added to the Star Network by just extending a cable from the hub. If the hub adds a device for example a printer or a fax machine, all the other computers on the network can access the new device by simply accessing the hub. The device need not be installed on all the computers in the network. The central function is cost effective and easier to maintain. If the computers are reasonably close to the vertices of a convex polygon and the system requirements are modest. And also when one computer falls short then it wont affect the whole communication. (http://searchnetworking.techtarget.com/dictionary/definition/what-is-star-network.html#) 3.1.5 Centralization: the star topologies ease the chance of a network failure by linking all of the computers to a central node. All computers may therefore communicate with all others by transmitting to and receiving from the central node only. Benefits from centralization: As the central hub is the bottleneck, increasing capacity of the central hub or adding additional devices to the star, can help scale the network very easily. The central nature also allows the check up of traffic through the network. This helps evaluate all the traffic in the network and establish apprehensive behavior (http://www.buzzle.com/articles/advantages-and-disadvantages-of-different-network-topologies.html). 3.1.6 Easy to troubleshoot: in a star network the whole network is reliant on the hub so if the entire network is not working then there could be a problem with the hub. This feature makes it easy to troubleshoot by offering a single point for error connection ad at the same time the dependency is also very high on that single point 3.1.7 Better performance: star network prevents unnecessary passing of the data packet through nodes. At most 3 devices and 2 links are involved in any communication between any two devices which are part of this topology. This topology encourage a huge overhead on the central hub, however if the central hub has plenty of capacity, then very high network used by one device in the network does not affect the other devices in the network. Data Packets are sent quickly as they do not have to travel through any unnecessary. The big advantage of the star network is that it is fast. This is because each computer terminal is attached directly to the central computer (http://en.wikipedia.org/wiki/Star_network). 3.1.8 EASY INSTALLATION: Installation is simple, inexpensive, and fast because of the flexible cable and the modular connector. 3.2 DISADVANTAGES OF STAR NETWORK 3.2.1 If the hub or concentrator fails, nodes attached are disabled: The primary disadvantage of a star topology is the high dependence of the system on the functioning of the central hub. While the failure of an individual link only results in the isolation of a single node, the failure of the central hub renders the network inoperable, immediately isolating all nodes. (http://www.buzzle.com/articles/advantages-and-disadvantages-of-different-network-topologies.html ) 3.2.2 The performance and scalability of the network also depend on the capabilities of the hub. Network size is limited by the number of connections that can be made to the hub, and performance for the whole network is limited by its throughput. While in theory traffic between the hub and a node is isolated from other nodes on the network, other nodes may see a performance drop if traffic to another node occupies a significant portion of the central nodes processing capability or throughput (http://en.wikipedia.org/wiki/Star_network). Furthermore, wiring up of the system can be very complex. 3.2.3 The primary disadvantage of the star topology is the hub is a single point of failure: If the hub were to fall short the whole network would fail as a result of the hub being connected to every computer on the network. There will be communication break down between the computers when the hub fails. 3.2.4 Star topology requires more cable length: When the network is being extended then there will be the need of more cables and this result in intricate installation. 3.2.5 More Expensive than other topologies: it is expensive due to cost of the hub. Star topology uses a lot of cables thus making it the most costly network to set up as you also have to trunk to keep the cables out of harm way. Every computer requires a separate cable to form the network. . A common cable that is used in Star Network is the UTP or the unshielded twisted pair cable. Another common cable that is used in star networks is the RJ45 or the Ethernet cables 3.3 USAGES OF STAR NETWORK Star topology is a networking setup used with 10BASE-T cabling (also called UTP or twisted-pair) and a hub. Each item on the network is connected to the hub like points of a star. The protocols used with star configurations are usually Ethernet or local-talk. Token Ring uses a similar topology, called the star-wired ring (http://fallsconnect.com/topology.htm#a). Star Topology is the most common type of network topology that is used in homes and offices. In the Star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch. In a Star Network the best advantage is when there is a failure in cable then only one computer might get affected and not the entire network. Star topology is used to ease the probabilities of network failure by connecting all of the systems to a central node. This central hub rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, sometimes including the originating node. All peripheral nodes may thus communicate with all others by transmitting to, and receiving from, the central node only (From Wikipedia, the free encyclopedia). Star network is used to transmit data across the central hub between the network nodes. When a packet comes to the hub it transfers that packet to all nodes connected through a hub but only one node at a time successfully transmits it. In local area networks where the star topology is used, each machine is connected to a central hub. In contrast to the bus topology, the star topology allows each machine on the network to have a point to point connection to the central hub and there is no single point of failure. All of the traffic which transverses the network passes through the central hub. The hub acts as a signal booster or repeater which in turn allows the signal to travel greater distances. When it is important that your network have increased stability and speed, the star topology should be considered. When you use a hub, you get centralized administration and security control, low configuration costs and easy troubleshooting. When one node or workstation goes down, the rest of your network will still be functional. 4.0 APPENDIX As the name suggests, this layout is similar to a star. The illustration shows a star network with five workstations or six, if the central computer acts as a workstation. Each workstation is shown as a sphere, the central computer is shown as a larger sphere and it is a hub, and connections are shown as a thin flexible cable. The connections can be wired or wireless links. The hub is a central to a star topology and the network cannot function without it. It connects to each separate node directly through a thin flexible cable (10BASE-T cable). One end of the cable is plugged into the connector on the network adapter card (either internal or external to the computer) and the other end connects directly to the hub. The number of nodes you can connect to a hub is determined by the hub. 5.0 CONCLUSION A star network is a local area network in which all computers are directly connected to a common central computer. Every workstation is indirectly connected to every other through the central computer. In some star networks, the central computer can also operate as a workstation A Star Network Topology is best suited for smaller networks and works efficiently when there is limited number of nodes. One has to ensure that the hub or the central node is always working and extra security features should be added to the hub because it s the heart of the network. To expand a star topology network, youll need to add another hub and go to a star of stars topology. In a Star Network Topology it is possible to have all the important data backups on the hub in a private folder and this way if the computer fails you can still use your data using the next computer in the network and accessing the backup files on the hub. 6.0 REFERENCES Available on http://en.wikipedia.org/wiki/Star_network Available on http://en.wikipedia.org/wiki/Very_small_aperture_terminal Available on http://fallsconnect.com/topology.htm#a Available on http://searchnetworking.techtarget.com/dictionary/definition/what-is-star-network.html#(above) Available on http://www.answers.com/topic/star_network Available on http://www.buzzle.com/articles/advantages-and-disadvantages-of-different-network-topologies.html Available on http://www.buzzle.com/editorials/2-6-2005-65413.asp Available on http://www.blurtit.com/q826101.html
