Equality, Diversity and inclusion in work with children and young people. Essay

1.1 How does the equality Act 2010 promote equality and diversity? Obtain your schools Equality of opportunity policy. What is its aim? Identify references to action. The Equality Act protects individuals from unfair treatment and promotes a fair more equal society. Equality and diversity is now a ‘limiting judgement’ in Ofsted inspections. This means that if equality measures are not being implemented efficiently, this will restrict the overall inspection grade. As a school, you must not discriminate against a pupil or prospective pupil because of their disability, race, sex, gender reassignment, religion or belief, or sexual orientation. The objectives at Tutshill School are that all children in our school will learn in an environment free from the effects of and without discrimination, and that the working conditions and environment of our staff and volunteers will also be free from discrimination. Tutshill C of E Primary School strives to ensure that the culture and ethos of the school are such that, whatever the heritage and origins of members of the school community, everyone is equally valued and treats one another with respect. Pupils should be provided with the opportunity to experience, understand and celebrate diversity. Tutshill School will adhere to Gloucestershire LEA’s Racial Harassment in Schools – Guidelines and make all new teachers, student teachers and ancillary staff aware of the policy. 1.2 Why is it important to support the rights of all children and young people to participation and equality of access? All children have the right to access all the opportunities which are on offer in the school provision. Each and every pupil has the right to learn and should not be discriminated against for any reason. In order for us to  achieve this we must involve the children and parents in finding out what works well in school and what doesn’t. This should be supported by high quality teaching and learning experience. I believe that involving the children in this process would make the children more confident and feel more valued within school. 1.3 How is cultural diversity valued and promoted in your school? Discuss its importance. Within Tutshill School opportunities are provided for all children to experience others cultures and ethnic backgrounds. This is promoted through literacy lessons. Every term the children I work with have a new topic for example, Greece and The Romans. With each topic they learn about their cultures such as their religion, language and the different foods they eat. The children in year four studied the Romans and did a play for the other children in assembly and also designed a menu for the whole school to try. The Year five class studied Greece and designed and made holiday brochure for display in their class room and also designed a Greek menu for the school to try. This is to ensure that the children understand and value the social and cultural diversity that could be in their own community as well as around the world. Culture can cut across nationalities and faiths and by promoting cultural diversity and the differences of individuals and groups within school will enhance a child ’s learning and promote knowledge and understanding of all pupils. Diverse cultures in schools should be acknowledged and reflected throughout the curriculum. By supporting and encouraging children to understand and accept cultural diversity will also prevent stereotyping and reduce prejudice and discrimination within schools. Most importantly, it will prepare children and young people for numerous changes that will happen in their lives as adults where they will inevitably be involved in mixing with adults of different cultures and backgrounds. Having watched the Teachers’ TV programme ‘Pride and Prejudice’, about Gypsy, Roma and Traveller children, comment on the following. 2.1 What prejudices do these groups face? Gypsy, Roma and Traveller children face many prejudices throughout their lives. They are not considered part of the community that they live in and often come up against racism, stereotyping, discrimination and abuse not only from other children but adults as well. 2.2 What impact does this have on traveller C/YP? The impact that racism, stereotyping and discrimination have on the children is that they fall out of school or are taken out of school at an early age. Majority of traveller children tend to leave school or are taken out of school at the end of primary level as they find the transition into secondary school a difficult one due to other children and teachers bulling them and having little knowledge or understanding of their culture. The remainder of the children do not often make it past year 9. 2.3/2.4 How have schools tackled prejudice to raise attendance and attainment? Schools have tackled these prejudices by increasing other people’s knowledge about these minority groups. For Example: †¢Celebrate their culture. †¢Looking at the history of the travellers. †¢Increasing awareness of their heritage by having day trips to the Romany life centre. †¢Traveller children making a booklet to educate teachers and pupils, about their religion and how and where they live. †¢Showing the pupils a film about travellers about their skills and how they made a living. To raise attendance and attainment schools have been flexible with rules regarding attendance rates and given extra support especially just before SAT’s. The most important thing I feel is that they treated each and every child the same. 3.1 Explain what is meant by ‘inclusion’? Inclusion means to be fully included, to make people feel valued and respected irrespective of ethnicity, gender, disability, culture, age, religion and sexual orientation. It is about giving equal access and opportunities to everyone. 3.2/3.3 Provide 3 or 4 examples of inclusive practices in your classroom/school. During my time at Tutshill School I have witnessed and been part of several inclusive practices. Example 1. Within year 4 we have a student who is Chinese. During the Chinese New-year SL brought in sweets for everyone so we could celebrate the Chinese new-year with her. She then had time to talk to the class about what she did during their celebrations. Example 2. Throughout each classroom and the school there are displays of children’s work. All abilities are displayed, so the children can see and understand that just because their work may not be the neatest or always correct it will still get to be displayed. Example 3. During P.E all children will be included, whether they have a lower ability or any medical issues. The games that they are playing will be adapted if needed to so that every child has the opportunity to participate.

Abraham  Lincoln  Ã¢â‚¬â€œ the  statesman  of  the  USA,  one of the founders of the Republican Party, the 16th US president who freed the slaves, the national American hero – was born in village Hodgenville (Kentucky) on February 12, 1809.

Women in Sports Essay Example | Topics and Well Written Essays - 1500 words

Women in Sports - Essay Example Women participation in sports/Olympics Considering the historical background of women participation in the Olympics, it is obvious that women have enjoyed nominal representation in ancient games. As Barbara L. Drinkwater comments; â€Å"Although the modern Olympic Games actually began in 1896, women were not permitted to participate† (Drinkwater & Inthe international Federation of Sports Medicine xi). Research professionals consider Amsterdam Olympics as a special one. This Olympics achieved international attention because of its women representation. In this game, a female participant had won the gold medal in Olympics history. Betty Robinson Schwartz is considered as the first female gold winner in the Olympics. In the Amsterdam Olympics, she created a new history in track and field (Zabell). Women fol,k have faced severe discrimination from the part of authorities and male community. Historical studies prove that the patriarchal society never ready to keep the achievements of women in the Olympics and other ceremonies. In 396 B.C. Olympics, Kyniska, a Spartan princess, won an Olympic chariot race, but she is banned from accumulating her prize in person (Anthony & suffragist). The problem of social attitude towards women part he participated in some sports items contributes supplementary causes for poor female representation. In the case of boxing, it is clear that the game requires a higher level of physical fitness and it is more stereotypically supposed for men. Boxing constitutes a psychological as well a physiological pace in which tension and emotional frustrations the can be revealed through the use of ropes and corners posts (Scott & Conover 40). Lack of opportunities for women in participating sports programs plays a vital role in the process of lowering women participation in sports and games.â€Å"Furthermore, in many countries, women have scarcely any opportunity of taking a sport in their leisure time† (Drinkwater & International Fe deration of Sports Medicine 17). Another important thing is that society always treats the woman as secondary to man. People never ready to admit to women participation in sports. Female’s sports participation turns down more speedily with age than does that of male, and is more vulnerable to the impact of family and domestic reasons sibilities than men (Houlihan 92). Considerable changes have been remarked in the field of women participation in the Olympics. A kind of gradual development in female participation in sports events and other physical activities. In 1900 Parris Olympics two items were included for women. The period from 1976 t0 88 was recorded by active women representation in sports and games (Lam & Chang 153). After that International Olympic Council (IOC) revived its manual and ensures active female representation in sports and games without gender discrimination.

Data Minining and Data Discovery Research Paper

Data Minining and Data Discovery - Research Paper Example However, the data that is analyzed via different techniques is fetched from data warehouses, where many databases are interconnected with each other. Major techniques that are involved in the process of data miming are regression, classification and clustering. Data mining is incorporated for gaining in depth patterns for market intelligence from data warehouses containing massive amount of data. However, the issue that arises is not the quantity of data, as we already have massive amount of data to work with, it is the methodology that is required to learn data. 3 Data Mining 3NF is usually recommended for a corporate environment managing massive amount of replicated data. For instance there is no requirement of saving data several times. However, there is a requirement of doing more joins. Comparatively, 1NF will provide the functionality of storing replicated data regardless of number of joins. It is the choice of database administrator to evaluate what is the right form; it may b e 3NF or 1 NF. Moreover, normalization comprises of five rules that are applied on a relational database. The main objective is to eliminate or minimize the redundancy and at the same time increasing database efficiency. The negative part illustrates that too much implementation of normalization can cause issues. The objective is to deploy the highest acceptable level of normalization. If we compare three of these NF’s, the 1NF removes replication in groups. The 2NF reduces data replication or redundancy and the 3NF reduces columns from the tables that are not reliant on primary keys. Therefore, database design must demonstrate the highest level of normalization possible, in order to make database efficient and robust. In order to maintain 3 large databases for a VLDB and to keep them efficient for two years if required, there is a requirement for constructing a ‘store and forward’ mechanism that will process the data or information from and through each distribu tion center database. Likewise, at the same time embrace that data or information pending till the completion of EDW. Moreover, data archiving is also required for maintaining each distribution center becoming a VLDB. EDW is efficient enough to support this scenario. A study demonstrated the overall cost of this disease throughout the world is $376 Billion annually. It is now almost fundamental that a person exceeding an age of 60 have more chances to get this disease, as it is now considered as the fourth largest live taking disease globally along with making its name for the fourth most common disease that contributes to a death of a person. However, the most common of all diabetes is the type 2. As there are almost 20% habitants suffering from in the United Arab Emirates alone, many research studies and debates are conducted yearly in Dubai and Abu Dhabi. Moreover, awareness sessions are conducted in every town of the cities to aware the people about this disease (MoH launches se cond phase of diabetes campaign.2010). However, this case study demonstrates the disease diabetes and medical data associated with patients from the Middle east region i.e. United Arab Emirates for discovering concealed patterns and the valuable information that can be utilized for decision making process. In addition, these informed decisions are performed by medical personnel

Analysis of Terrorist Attacks in International Law Research Paper

Analysis of Terrorist Attacks in International Law - Research Paper Example Hague Convention considers the unlawful seizure of an aircraft, an international criminal offense and even the accomplices of the hijackers are charged with the same offense and even the states that get connected to the offense are asked to abide with the international law of hijacking. "The Convention requires each contracting state to take such measures as may be necessary to establish its jurisdiction over the offense when the offense is committed on board an aircraft registered in that state, or when the aircraft lands in that state with the offender on board, or when the alleged offender is present in its territory and it does not extradite him to one of the other states just mentioned" American Society of International Law.1" The use of the hijacked aircraft as lethal weapons, resulting in the deaths of hundreds if not thousands of persons, may be a crime against humanity under international law. The Statute of the International Criminal Court, which is in the process of obtaining the necessary ratifications to enter into force, defines a crime against humanity as any of several listed acts "when committed as part of a widespread or systematic attack directed against any civilian population, with knowledge of the attack." The acts include murder and "other inhumane acts of a similar character intentionally causing great suffering, or serious injury to body or to mental or physical health." When the attack happened in 2001 on the World Trade Centre, the International Criminal Court was not yet functioning. Still, the crimes were held as crimes against humanity that would be subject to all domestic criminal courts of the world and eventually they came under the jurisdiction of International Criminal Court. Under the jurisdiction of international law, not only any country could try the terrorists for the terrorist acts within the borders of that particular country irrespective of their nationality and citizenship according to the statutes that are in force, but also the terrorists could be sent to another country for trial if that country's grievance against such terrorists is more severe. All the countries can exercise the universal jurisdiction for the crimes committed against their State. According to the universal law, any country can bring such terrorist offenses under its own law and prosecute the offenders if 'they are within its custody'.International law issues can also crop up if any country is obviously harboring terrorists who have already committed acts of terrorism anywhere in the world. Military action against such a country is definitely not advised, but the country could be the target of many other international actions like sanctions, trade embargos etc. If there is an extradition treaty between the two countries, it should be honored immediately and not doing so, can earn the status of a rogue nation to the un-obliging country.

Service Marketing Research Paper Example | Topics and Well Written Essays - 3250 words

Service Marketing - Research Paper Example Talking about the various means of travelling in UK, the prominent ones are trains, ships and airways. All the three have become really advanced and providing great facilities and services to its clients. Now the journey is no more called as the boring time as the companies do their best to make the traveler feel like home and provide the quality time spent during travelling. There are number of companies who have already stepped into this industry as it is profit earning business and that has provoked a tight competition. Therefore any newbie has to struggle hard so that to make its place in this business. Before deciding any particular sector, let’s have a look at the general overview of the three main travelling means. Airways: UK major industry emphasize on the airways. According to the recent facts and figures, 235 million people use this means to travel a year and 2.3 million tonnes of freight is carried out via airways. In the recent years, the number of air travelers h as increased because of the fact that the income of people has also increased. Additionally, the time factor is most important thing that is considered today and airways is one of the fastest means of travelling. Aviation business is operated commercially and privately without subsidy. Therefore it is very important to plan out everything in prior and have negotiations with other countries’ aviation sector. Proper strategies and policies are required to be developed that support the department for long term. This business runs in collaboration of different departments like an airport, airlines, regulators and government sectors. In addition to this, they need support of international governments, embassies, customer representatives and trade associations as well. Civil Aviation Authority is the main department that regulates this industry. It keeps the record of safety, economic, airspace policy and consumer protection regulation. CAA is the department who negotiates with the government on issues of aviation, customer interests and also establishes statistical data after collecting information via economic and scientific research. In UK, air traffic management services are being provided by National Air Traffic Services (NATS) that is being regulated by the CAA. There are two main shareholders of NATS; one is the Government and the other Airline group consists of 7 UK airlines. In previous years, most of the people used to travel via trains and ships as because of the low rates. But now after the airlines have started offering low rates, the air travelling has become affordable for the mediocre person as well. But still due to the economic and security conditions there are many people who prefer to travel via means of ship or trains. Secondly, majority people use only trains and buses for the short distance travelling as it cost them much less. Therefore the trains and buses are big substitute threat for the airlines. Opportunities and threats to Airlin es Since the last few years, airline business is bearing major losses due to some reasons like first due to the security reasons after 9/11 issue then the recession period made it difficult for the people to afford high rates of the airlines. The International Air Transport Association (IATA) estimated loss of approximately $4.7 billion in 2009. Revenues were predicted to decrease by 12%. According to the facts and figures, Airlines bear loss of

Tessellation Pattern Essay Example | Topics and Well Written Essays - 500 words

Tessellation Pattern - Essay Example With vivid lines and basic definite shape, I find it conducive to come up with a tessellation of the ‘barking dog’ for its concrete details can be readily visualized to end up with sharp geometric tessellated form. It is more convenient I suppose to tessellate with straight rather than curved edges of the model in the process. Using MS Paint of the Windows accessories, I first cropped the image to make a barking dog-pattern then copied and pasted the same pattern in a row. The initial transformation would be to translate each common figure vertically then reflect it about the vertical axis so as to show a row of barking dog images on top and at the bottom of the one bearing the original pattern. In this manner, the tessellation design consists of rows in original and reverse positions of the barking dog image alternating each other in two shades – brown and pink. By horizontally flipping a line of mass generated figure with a row of the first orientation placed on top of the second, there emerges ease in yielding a sight of the entire object. Monotonousness is further reduced in this technique since transforming by means of translating reflections creates spatial balance at least, if not symmetry. It would feel as if the tessellated product is less complex in view especially that in between the sol id pink and the solid brown, an external structure cut-out that traces the source pattern also alternates in solid shades of maize and blue gray on application of the same transformation scheme.

Estimation of Weighted Average Cost of Capital Essay

Estimation of Weighted Average Cost of Capital - Essay Example The paper also discusses the various project evaluation techniques like Net Present Value Method, Internal Rate of Return, and so on. The paper takes a quantitative approach for the explanation of various concepts in Capital Structure and Project Evaluation Techniques/Capital Budgeting Techniques. Cost of capital is an important phenomenon in determining the overall/weighted average cost of capital. In fact, the financial risk is judged by investors and other stakeholders in line with cost of capital and nature of capital structure. The overall cost of capital can be reduced and value of the firm can be improved by maximizing the debt content in the capital structure. But, as debt content goes on increasing, equity investors expectations about risk will also change. Investors feel risk in investment with highly levered firms and vice versa. Capital structure theories postulate the various possibilities of capital structure. It does not speak about which approach is most beneficial to companies in various situations. Capital structure is not a static phenomenon. It keeps on changing with every change in the mix of various sources of capital/fund. The profitability of a business proposal/ project can be evaluated in various ways using both discounted and non-discounted project evaluation methods.

Close examination of global financial systems Essay

Close examination of global financial systems - Essay Example Not only is the existing function of German universal banking overemphasized, it perhaps never was as important as advocated, even at its peak by the turn of the century. The image that appears is not constant with the claim that German universal banks applied considerable power on industrial businesses and offered large amounts of funding (Bongini et al, 2009, p. 76). Even though there were a number of instances of this, these were the exceptions to the general rule, which was for businesses to support themselves on the inside largely. Pragmatic study on the relative values of bank-based as well as market-based financial systems has focused on â€Å"Germany and Japan as bank-based systems and the United States and the United Kingdom as market-based systems† (World Bank, 2012, p. 111). The bank-based idea emphasizes on the constructive function of banks in activating resources, categorizing good ventures, supervising executives, and dealing with risk. The bank-based approach a s well emphasizes on the relative limitations of market-based systems. Especially, highly sensitive markets promptly expose data within public markets, which diminishes the inducements for individual shareholders to obtain information. Therefore, better market expansion may hinder inducements for classifying pioneering ventures that encourage development. Banks, on the other hand, alleviate this setback as they create continuing links with businesses and do not disclose data instantaneously within public. Advocates of the bank-based approach as well highlight that liquid markets form a prejudiced investor environment. In liquid markets, investors can economically trade their shares, so that they have smaller number of inducements to apply thorough corporate control. As a... After bringing up the main the main topic of the essay, we see that it makes a few valid points to argue about. Whereas the function of financial systems is argued, the performance of different types of financial systems is even more greatly argues. Banks in Germany are mainly accountable for the growth of the nation, having promoted and developed its industries. To them, more than any other group may be attributed the wonderful outcomes yet realized. The essay goes deeper into the topic by bringing other examples. Pragmatic study on the relative values of bank-based as well as market-based financial systems has focused on â€Å"Germany and Japan as bank-based systems and the United States and the United Kingdom as market-based systems† (World Bank, 2012, p. 111). The essay says that theoretically, the financial services notion is completely compatible with both the bank-based as well as market-based approaches. Later, we are given pieces of advice, such as: when trying to con trol the design of a financial system, the study recommends that supervisory bodies should not intently concentrate on banks and markets independently, but rather see them as essential components of a co-developing system. In conclusion, we see that when trying to control the design of a financial system, the study recommends that supervisory bodies should not intently concentrate on banks and markets independently, but rather see them as essential components of a co-developing system.

Network Typologies Essay Example for Free

Network Typologies Essay A network is a system of two or more computers that are connected in some manner. Each computer on the network has access to the files and peripheral equipment (such as printers or modems) on all the other computers on the network. The origin of local area networks can be traced, in part, to IBM terminal equipment introduced in 1974. At that time, IBM introduced a series of terminal devices designed for use in transaction-processing applications for banking and retailing. What was unique about those terminals was their method of connection: a common cable that formed a loop provided a communications path within a localized geographical area. Unfortunately, limitations in the data transfer rate, incompatibility between individual IBM loop systems, and other problems precluded the widespread adoption of this method of networking. The economics of media sharing and the ability to provide common access to a centralized resource were, however, key advantages, and they resulted in IBM and other vendors investigating the use of different techniques to provide a localized communications capability between different devices. However, Datapoint Corporation began selling its Attached Resource Computer Network (ARCNet), considered by most people to be the first commercial local area networking product. Since then, hundreds of companies have developed local area networking products, and the installed base of terminal devices connected to such networks has increased exponentially. They now number in the hundreds of millions. Designing a manageable network One of the most important considerations in designing a network to be manageable is deciding how and where to connect the network-management equipment. Is there a separate network-management center to accommodate? Do nonoperational staff members like the network designer sit in a different area? Do they require access to the network-management centers equipment through the network? In general, the design should include a separate virtual local area network (VLAN) just for network-management equipment. The management VLAN was used to access management functions on remote network equipment. This network management-equipment VLAN houses servers and workstations used to manage the network. Design Types A large-scale network design is composed of several common building blocks. Every LAN, of whatever size, has to have an access system by which the end stations connect to the network. There are several inexpensive options for LAN connections, such as Ethernet and Token Ring. As a philosophical principle, the network should be built using basic commonly available technology. The design shouldnt have to reinvent any wheels just to allow the machines to talk to one another. So, just as basic commonly available technologies exist for connecting end stations to LANs, there are common methods for interconnecting LAN segments. Once again, these technologies and methods should involve the most inexpensive yet reliable methods. But in this stage of interconnecting, aggregating, and distributing traffic between these various LAN segments, the designer may run into some serious hidden problems. There may be thousands of ways to connect things, but most of these methods result in some kind of reliability problems. Network topology The topology of a local area network is the structure or geometric layout of the cable used to connect stations on the network. Unlike conventional data communications networks, which can be configured in a variety of ways with the addition of hardware and software, most local area networks are designed to operate based on the interconnection of stations that follow a specific topology. The most common topologies used in LANs include the loop, bus, ring, star, and tree, as illustrated in the figure below Loop As previously mentioned, IBM introduced a series of transaction-processing terminals in 1974 that communicated through the use of a common controller on a cable formed into a loop. This type of topology is illustrated at the top of Figure below. Local area network topology. The five most common geometric layouts of LAN cabling form a loop, bus, ring, star, or tree structure. Because the controller employed a poll-and-select access method, terminal devices connected to the loop require a minimum of intelligence. Although this reduced the cost of terminals connected to the loop, the controller lacked the intelligence to distribute the data flow evenly among terminals. A lengthy exchange between two terminal devices or between the controller and a terminal would thus tend to weigh down this type of network structure. A second problem associated with this network structure was the centralized placement of network control in the controller. If the controller failed, the entire network would become inoperative. Due to these problems, the use of loop systems is restricted to several niche areas, and they are essentially considered a derivative of a local area network. Bus In a bus topology structure, a cable is usually laid out as one long branch, onto which o ther branches are used to connect each station on the network to the main data highway. Although this type of structure permits any station on the network to talk to any other station, rules are required for recovering from such situations as when two stations attempt to communicate at the same time. Ring In a ring topology, a single cable that forms the main data highway is shaped into a ring. As with the bus topology, branches are used to connect stations to one another via the ring. A ring topology can thus be considered to be a looped bus. Typically, the access method employed in a ring topology requires data to circulate around the ring, with a special set of rules governing when each station connected to the network can transmit data. Star The fourth major local area network topology is the star structure, illustrated in the lower portion of Figure 1. In a star network, each station on the network is connected to a network controller. Then, access from any one station on the network to any other station can be accomplished through the network controller. Here, the network controller functions like a telephone switchboard, because access from one station to another station on the network can occur only through the central device. In fact, you can consider a telephone switchboard or PBX as representing a star-structured LAN whose trunks provide connections to the wide area network telephone infrastructure. Tree A tree network structure represents a complex bus. In this topology, the common point of communications at the top of the structure is known as the head-end. From the head-end, feeder cables radiate outward to nodes, which in turn provide workstations with access to the network. There may also be a feeder cable route to additional nodes, from which workstations gain access to the network. One common example of a tree structure topology is the cable TV network many readers use on a daily basis. With the upgrade introduction to networking of many cable TV systems to two-way amplifiers and the support of digital transmission, the local cable TV infrastructure can be considered to represent an evolving type of tree-structured local area network. Mixed Topologies Some networks are a mixture of topologies. For example, a tree structure can be viewed as a series of interconnected buses. Another example of the mixture of topologies is a type of ethernet known as 10BASE-T. 10BASE-T network can actually be considered a star-bus topology, because up to 16 or 24 devices known as stations are first connected to a common device known as a hub, which in turn can be connected to other hubs to expand the network. Transmission Medium Used in LAN. The transmission medium used in a local area network can range in scope from twisted-pair wire, such as is used in conventional telephone lines, to coaxial cable, fiber-optic cable, and electromagnetic waves such as those used by FM radio and infrared. Each transmission medium has a number of advantages and disadvantages. The primary differences between media are their cost and ease of installation; the bandwidth of the cable, which may or may not permit several transmission sessions to occur simultaneously; the maximum speed of communications permitted; and the geographic scope of the network that the medium supports. Twisted-pair wire In addition to being the most inexpensive medium available for LAN installations, twisted-pair wire is very easy to install. Since this wiring uses the same RJ11 and RJ45 modular connectors as a telephone system, once a wire is cut and a connector fastened, the attachment of the connector to network devices is extremely simple. Normally, a screwdriver and perhaps a pocket knife are the only tools required for the installation of twisted-pair wire. Anyone who has hooked up a pair of speakers to a stereo set has the ability to install this transmission medium. Unshielded twisted-pair Although inexpensive and easy to install, unshielded twisted-pair (UTP) wire is very susceptible to noise generated by fluorescent light ballasts and electrical machinery. In addition, a length of twisted-pair wire acts as an antenna; however, the twists serve as a mechanism to partially counteract this antenna effect. Unfortunately, due to the law of physics, the longer the wire length, the greater the noise it gathers. At a certain length, the received noise will obliterate the signal, which attenuates or decreases in strength as it propagates along the length of the wire. This noise can affect the error rate of data transmitted on the network, although lead-shielded twisted-pair (STP) cable can be employed to provide the cable with a high degree of immunity to the line noise and enable extended transmission distances. Examining a building cabling standard and the various categories of twisted-pair that can support different transmission rates which, in turn, enable different types of Ethernet networks to be supported. Because the bandwidth of twisted-pair cable is considerably less than coaxial or fiber-optic cable, normally only one signal is transmitted on this cable at a time. Although a twisted-pair wire system can be used to transmit both voice and data, the data transmission is baseband because only one channel is normally used for data. In comparison, a broadband system on coaxial or fiber-optic cable can be designed to carry voice and several sub channels of data, as well as fax and video transmission. Other constraints of unshielded twisted-pair wire are the rate at which data can flow on the network and the distance it can flow. Although data rates up to 1 gigabit per second (Gbps) can be achieved, normally local area networks employing UTP wiring operate at a lower data rate. In addition, UTP systems normally cover a limited distance, measured in terms of several hundred to a few thousand feet, while coaxial and fiber-optic cable–based systems may be limited in terms of miles. Extending transmission distances over twisted-pair wire requires the periodic insertion of repeaters into the cable. A repeater receives a digital signal and then regenerates it; hence, it is also known as a data regenerator. Coaxial cable At the center of a coaxial cable is a copper wire, which is covered by an insulator known as a dielectric. An overlapping woven copper mesh surrounds the dielectric, and the mesh, in turn, is covered by a protective jacket consisting of polyethylene or aluminum. The figure below illustrates the composition of a typical coaxial cable; however, it should be noted that over 100 types of coaxial cable are currently marketed. The key differences between such cables involve the number of conductors contained in the cable, the dielectric employed, and the type of protective jacket and material used to provide strength to the cable so it can be pulled through conduits without breaking. Two basic types of coaxial cable are used in local area networks. The type of cable used is based on the transmission technique employed: baseband or broadband signaling. Both cable types are much more expensive than twisted-pair wire; however, the greater frequency bandwidth of coaxial cable permits higher data rates for longer distances than you can obtain over twisted-pair wire. Normally, 50-ohm coaxial cable is used in baseband networks, while 75-ohm cable is used in broadband networks. The latter coaxial is identical to that used in cable television (CATV) applications, including the coaxial cable used in a home. Data rates on baseband networks using coaxial cable range from 50 to 100 Mbps. With broadband transmissions, data rates up to and including 400 Mbps are obtainable. A coaxial cable with a polyethylene jacket is normally used for baseband signaling. Data is transmitted from stations on the network to the baseband cable in a digital format, and the connection from each station to the cable is accomplished by the use of a simple coaxial T-connector. Because data on Coaxial cable. baseband network travels in a digital form, those signals can be easily regenerated by the use of a device known as a line driver or data regenerator. The line driver or data regenerator is a low-cost device that is constructed to look for a pulse rise, and upon detecting the occurrence of the rise, it will disregard the entire pulse and regenerate an entirely new pulse. Thus, you can install low-cost line drivers into a baseband coaxial network to extend the distance over which transmission can occur on the cable. Typically, a coaxial cable baseband system can cover an area of several miles, and may contain hundreds to thousands of stations on the network. Obtaining independent sub channels defined by separate frequencies on coaxial cable broadband transmission requires the translation of the digital signals from workstations into appropriate frequencies. This translation process is accomplished by the use of radio-frequency (RF) modems, which modulate the digital data into analog signals and then convert or demodulate received analog signals into digital signals. Because signals are transmitted at one frequency and received at a different frequency, a head-end or frequency translator is also required for broadband transmission on coaxial cable. This device is also known as a demodulator, as it simply converts the signals from one sub channel to another sub channel. Fiber-optic cable Fiber-optic cable is a transmission medium for light energy, and as such, provides a very high bandwidth, permitting data rates ranging up to billions of bits per second. The fiber-optic cable has a thin core of glass or plastic, which is surrounded by a protective shield. Several of these shielded fibers are bundled in a jacket, with a central member of aluminum or steel employed for tensile strength. Digital data represented by electrical energy must be converted into light energy for transmission on a fiber-optic cable. This is normally accomplished by a low-power laser, or through the use of a light-emitting diode and appropriate circuitry. At the receiver, light energy must be reconverted into electrical energy. Normally, a device known as a photo detector, as well as appropriate circuitry to regenerate the digital pulses and an amplifier, are used to convert the received light energy into its original digital format. The figure below provides an illustration of the cross sectio n of a single-strand fiber cable. The cladding that surrounds the core of the fiber can be considered to represent a cylindrical mirror whose job is to ensure light stays in the core as it flows along the fiber. The Kevlar fibers add strength to the cable, while the outer jacket, which is commonly colored orange, represents a polymer-based shield that protects the cable from the elements. There are two key factors that govern the manner by which light flows through a fiber-optic cable. Those factors are the diameter of the core and the light source. The first type of fiber-optic cable developed had a relatively large diameter that ranged from 50 to 140 microns, where a micron is a millionth of a meter. The original light source used to transmit information was a light-emitting diode (LED). Horizontal cross section of a single-strand fiber cable The coupling of an LED to a large-diameter optical fiber results in photons flowing along multiple paths through the optical fiber, resulting in the transmission referred to as multimode, which is also the same name used to reference the type of optical fiber. There are two types of multimode fiber, referred to as step-index and graded index. A step-index fiber has a core with a uniform refractive index, resulting in the different components of a light signal in the form of modes or rays flowing in a non-uniform manner through the optical cable. The top portion of the figure below illustrates the flow of light through a step-index, multimode fiber. In a graded-index multimode fiber, the refractive index is varied from the center to the edge of the core to minimize modal dispersion. The middle portion of the figure below illustrates the flow of light through a graded-index, multimode fiber. This type of fiber minimizes model dispersion and supports higher data rates than a step-index multimode optical fiber. A third type of optical fiber has a relatively small core diameter, typically between 7 and 12 microns (10−6 meters). This type of optical fiber permits only one path for the flow of light due to the small diameter of the core. As a result of the lack of modal dispersion, single mode supports a much higher data rate than multimode fiber. Because of the small diameter of single-mode fiber, lasers are used as the light source instead of LEDs. Both the core thickness and the cladding of an optical fiber are measured in microns. The three major core thicknesses used in optical fiber are 50, 62 and 100 microns. The associated claddings for those core diameters are 125 and 140 microns, respectively. Light flow in multimode and single-mode optical fiber. Computer networks are everywhere; from a simple two-node home setup to the vast number of computers on the internet. However, any computer network includes certain basic components, regardless of which operating system one is running. Network scope refers to the extent to which a network provides coverage. There are two major divisions of network scope; Local Area Networks and Wide Area Networks. †¢ A Local Area Network (LAN) consists of any number of computers that are linked directly together and are housed in a clearly defined geographic area, such as in a single building or campus. A LAN can only be as large as the physical limitations of the cabling you use which also depends on the cabling type. Usually the computers linked together in a LAN are workstations that can access data on computers on the same LAN, and use devices like printers that are connected to the LAN. †¢ A Wide Area Network (WAN) can span large geographic areas like countries and continents. WANs often contain two or more LANs. At least some of the connections used in WAN rely on long distance communications media such satellite links, long distance fiber optic cable, or specialized high speed telephone lines. WAN technology is essentially used to link all the computers in a multi-site or multinational enterprise in a reliable way Note that the key characteristic of a LAN or WAN is not how big it is, but rather the technologies used to connect the computers. There are other more specialized scopes used to describe networks. These include: †¢ Metropolitan Area Networks (MAN): this is a mini-wan or a giant LAN that is confined to a single municipality. A company might use a private MAN to link different offices together within the same compound. Computers on a MAN are linked using high-speed media like fiber optic or dedicated digital lines. This is the typical description of the IITA Ibadan network as will be discussed later. †¢ Storage Area Network (SAN): A specialized LAN linking several network servers that are dedicated to storing large amounts of data in a centralized secure repository. †¢ Personal Area Network (PAN): This is a connection you personally have with the technology that is around you (within your body) e.g. the way your cell phone communicates with your Bluetooth headset and your laptop. Bluetooth and infrared are currently the major types of PAN. Network Topology A network topology refers to the layout of the transmission medium and devices on a network. Topologies use either a point to point or multipoint connection scheme. A connection scheme indicates how many devices are connected to a transmission media segment or an individual cable. An example of point-to-point connection scheme is a printer or modem connected to your computer. Another is two computers connected directly to each other to use file transfer software like windows i.e. the network computer communicates with other network devices via direct cable connection between them. An example of a multi point connection scheme is a star or bus topology network. The entire physical structure of the network is called its physical topology. Star topology: This is a local area network topology where all the nodes are connected individually to a central connecting device called a hub. Signals travel from the nodes to the hub which then sends signals to other nodes on the network. A star topology network is easily scaleable – nodes can be added and removed fairly easily- and if a computer fails, none of the other nodes are affected. However if the hub fails the entire network fails. A hub does not perform any type of filtering or routing of the data. It is simply a junction that joins all the different nodes together.

Gay marriage should be legalized and accepted Essay Example for Free

Gay marriage should be legalized and accepted Essay Gay marriage (also known as same-sex marriage) generally refer to the marriage between two people with same sex can be either both male or both female. Imagine this, you and your beloved person walking on the street, everyone look at you in a strange way and mumble about you. How will you feel? That is how homosexual people feel these days. Remember this, they are just human beings like us but have different sexual orientation and that is the one and only difference. They can feel pain, happiness, sadness and lost just like how we feel, both physically and psychologically. It is one of our liberties to pursue happiness, which homosexual people are not able to chase, because they cannot marry the person they love. Who give you the right to take away others’ happiness? The happiness which did not and will not harm you. Are you racist? Are you sexist? Reasonable people will know that discriminate against anyone for any reason is rude and uneducated. And denying same-sex marriage sends the message of it is acceptable to discriminate against them. Some people may say that the institution of marriage has traditionally been defined as between a man and a woman, and allowing gay marriage will weaken the institution of marriage. This is absolutely nonsense. To not to change the institution is like to tell the court to not to change the law even when the law does not fit the modern world anymore. Nowadays, everything is changing as time passing by, so why not the institution of marriage. The legalization of gay marriage will also make it easier for same-sex couple to adopt, and provide stable home for children who otherwise be left in orphanage which hardly makes kids feel like home. Even gay marriage will lead to children being raised in same-sex household that lots of people may refer as not an optimum environment because children need both mother and father. However, according to a research by University of Melbourne lead by Doctor Simon Crouch which surveyed 315 same-sex parents and 500 children. The research shows that children who were raised in same-sex parents scored an average of 6% higher then general population on both health and family cohesion. Clearly the evidence shows that the children who grown up in same-sex couple family won’t grow unhealthily, in fact sometimes it is even better for kids to gain more resilience, because all the kids need is no more than two loving parents. So how many lives should be ruined, how many happiness should be  taken away before we take actions?

The effects of a binding minimum wage

The effects of a binding minimum wage Introduction A binding minimum wage leads to numerous detrimental effects in a competitive labour market. This essay will highlight what these effects are, and what the outcome of these effects will bring to the labour market. A labour market is defined by Parkin as a market where employers are on the demand side and workers are on the supply side. Firms decide how much labour to demand, and the lower the wage rate, the greater is the quantity demanded (Parkin, et al., 2008). It is said to be competitive when there is a surplus of workers that are seeking a job, with few employers willing to hire. A minimum wage is a price floor implemented by the government, which ensures that an employer must pay a minimum rate of pay to an employee, and anything lower than this rate of pay is illegal. A minimum wage is binding if it is set above the equilibrium wage (Parkin, et al., 2008). With a binding minimum, wage adjustments are blocked and the market is prevented from allocating labour resources (Parkin, et al., 2008). The Effects 2.1 The Labour Market due to the minimum wage In the labour market, there is said to be an equilibrium wage. This is where the demand and supply lines on the minimum wage graph intersect, as it is the point that the rate of pay is equivalent to that of the quantity of hours worked/required. A binding minimum wage in a competitive labour market means that this equilibrium point is offset as the rate of pay must rises. This can be shown using the following graph (Parkin, et al., 2008). With relation to part (a) of the Parkins graph previously, it is evident that the wage rate of à ¢Ã¢â‚¬Å¡Ã‚ ¬5 on the Y axis is the equilibrium price, and 21 million hours per week is the equilibrium quantity on the X axis. The minimum wage is below the equilibrium wage rate and is not binding (Parkin, et al., 2008). Where the rate of pay has increased, and all employees are being paid a higher wage, the hiring company cannot afford to hire as many employees as it will be too expensive, because not only do they have to pay wages for the skilled jobs, they also have to pay a higher wage than they would have intended for workers to perform the lower skilled jobs. Therefore this means that there will be workers on the supply side who will not be able to get a job, thus the unemployment rate will rise. This can be shown in part (b) of the graph (Parkin, et al., 2008). With relation to part (b), it can be seen that the minimum wage is à ¢Ã¢â‚¬Å¡Ã‚ ¬6 an hour, which is above the equilibrium wage. The equilibrium wage is now illegal. At a minimum wage of à ¢Ã¢â‚¬Å¡Ã‚ ¬6 an hour, 20 million of hours of labour are demanded and 22 million hours are supplied (Parkin, et al., 2008). This difference that has been created due to the binding minimum wage creates a surplus of 2 million hours of work per week in the graph, which means that the unemployment rate now rises. This new minimum wage also means that unemployed workers are willing to supply the 20 millionth hour for à ¢Ã¢â‚¬Å¡Ã‚ ¬4 (Parkin, et al., 2008). 2.2 Inefficiency of the Labour market due to the minimum wage The minimum wage is not efficient, as Parkin states it results in unemployment wasted labour resources and an inefficient amount of job search (Parkin, et al., 2008). When looking at a minimum wage graph, a deadweight loss is present. This occurs because of a decrease in both the workers surplus and the companys surplus. This is seen in the following graph (Parkin, et al., 2008). Also seen in this inefficiency graph is a potential loss from job search. This loss is said to arise because someone who finds a job earns à ¢Ã¢â‚¬Å¡Ã‚ ¬6 an hour but would have been willing to work for à ¢Ã¢â‚¬Å¡Ã‚ ¬4 (Parkin, et al., 2008). This inefficiency affects the labour market as it means there is a deadweight loss of 1 million hours of work per year. 3.0 What might soften my interpretation? The use of a minimum wage brings numerous detrimental effects to people. When looking at the outcomes of a minimum wage, it delivers an unfair result and imposes unfair rules (Parkin, et al., 2008). Parkin also states that this is unfair because only those who can find a job benefit, whereas the unemployed end up worse off than with no minimum wage (Parkin, et al., 2008).

Sigmund Freud Essay -- essays research papers

Sigmund Freud In the 1920s, the world was changing dramatically. Underground salons were built, new architecture was used and modern dance was introduced. If it were not for certain people, the world would not be the way it is today. In the twenties, new theories and ideas in science and psychology were being presented daily. Sigmund Freud changed the world of psychology by presenting new and controversial ideas on psychology and having his theories published. Freud broke cultural boundaries as he fought scientists opposed to his books and continued to study the human mind. Freud truly helped change the world in the 1920s and his influence remains today. Sigmund Freud was born in the Austro-Hungarian Empire in 1856. His father was a small time merchant. Sigmund’s family moved to Vienna when he was four. Freud was very ambitious and a good student. In 1873, Freud entered the medical school of the University of Vienna. Freud was mainly interested in science and hoped become a neuropsychological researcher. However, because of his financial situation, Freud was unable to pursue his desired career. Researchers in the twenties had to be wealthy because they were paid based on their findings. While in medical school, Freud developed a friendship with Josef Breuer, another physician and psychologist. One of Josef Breuer’s patients was Anna O. Anna O. was a young woman who had a serious case of hysteria. She had temporary paralysis and could not speak her native language, though sh...

Sherwood Andersons paper Pills: Deception In The Title

Sherwood Anderson's "Paper Pills": Deception In The Title Sherwood Anderson, in the title â€Å"Paper Pills,† tries to persuade us, the readers, in believing the short story is going to be about some kind of drug. Anderson in the other hand turns every thing around to tell us a story about two people falling in-love. The story begins with a description of Doctor Reefy and a brief description of the young woman. Then he tells the reader about the â€Å" twisted apples† (71)that represent doctor Reefy. Anderson begins characterize Doctor Reefy in his opening paragraph. The reader is given some facial and body features of the doctor. The â€Å"... white beard a huge nose and hands† (71) that Anderson puts as a description, making Reefy seem old, ugly, and worn out to the reader. The doctor kept to himself after his wife died. Reefy started smoking a cob pipe and sat in his empty office by a window that he never opened. On a hot summer day the doctor tried to open the window but when the window did not budge, Reefy did not attempt to reopen the dusty window again. Reefy was so devastated about his wife passing away that he did not care about him self for over ten years. The young woman was well off and needs to find a husband to help her take care of the farm that she inherited from her parents. She was tall, dark, and beautiful with lots of money. As the unwanted â€Å"twisted apples† are left on the tree to rotten -- so is Do...

Essay --

When asked about a certain food, the first thing that might come to mind is the taste, the look, or the texture. What does not come to mind is the ingredients that make the food for what it is. Today, many food items contain the ingredient high fructose corn syrup. While some people may cringe when they hear those words, others will explain the true meaning behind HFCS. Based on several articles, the truth of the matter is that high fructose corn syrup is just another replacement for sugar. There is no sufficient evidence proving that HFCS is worse than sugar, however that does not mean it is better for you either. HFCS is just as bad as sugar, meaning that there is no large effect on the body compared to sugar, but they both do have side effects if over consumed. When comparing and contrasting high fructose corn syrup with sugar, the similarities outweigh the differences. For instance, in the â€Å"myth vs facts† article it claims that HFCS is the same as sugar when it comes to the number of calories, composition and absorption in the human body. In addition, when it comes to sweetne...

Femininity

Images in the media today illustrate an unrealistic and even dangerous standard of ideal female beauty hat can have a powerful influence on the way women perceive themselves. The popular culture influences our ides of femininity to the extent that we hold high expectations of a women's appearance. Society is driven to judge or neglect a woman if they don't kick a certain way because they compare them to the unrealistic models seen on magazines, television, music videos, and so on. The media impacts the ideas of femininity to the extent that women are portrayed as sex objects who exist primarily to service men, or as weak individuals.To initiate, mass media is a powerful tool that is used to impact TTS audience in various ways. For instance, when I'm surfing the internet shopping for clothing in websites such as (Forever 21, Hollister, or H & M,) the models I perceive are usually extremely thin. When I look at the model info the height of the model tends to be about 5'8†³ or tall er and the waist is typically between 23 and 25. The models shown are always wearing a size extra-small or small, and they always appear very young and beautiful.They have perfect facial features and many times have colored eyes. They never display a model wearing anything bigger than a size small almost as if earring a size medium or anything bigger is unacceptable. The ideal expected body is also perceived in beauty pageants such as the Latin show â€Å"Muenster Bella Latin. † Beauty pageants like these push women to exercise a great deal and follow strict diets in order to meet the ideal weight. In one of the episodes that I watched a girl was eliminated simply because she was about two or three pounds over the expected weight.Common women are compared to these ideal models and society believes that in order for a woman to be sexy or attractive they must resemble these models. As a result, any women are disappointed with their bodies and are forced to exercise excessively, suffer anorexia or other eating disorders because they are obsessed with the idea of thinness. Not only are women disappointed with their bodies, but also fear aging and they are driven to various methods such as surgery or anti-aging creams in order to maintain a young appearance.In addition, advertising adds to the ideal image that is expected of woman. Advertising is a powerful force that surrounds us and influences us subconsciously on a daily basis. Advertisements use Photos and create artificial images of women, and women in real life attempt to measure themselves against those images. It gives women the idea that there's only one way to look good and receive the attention they want or deserve. For example, bikini or lingerie advertisements always have extremely thin woman hinting that a thicker girl would not look good wearing that.Not only does advertising promote the ideal image of a woman, but it also influences the idea that women are just sex objects, and that they are the weaker sex. In many occasions advertisements utilize sex appeal by illustrating naked omen or men who are in control over a woman. In â€Å"Two Ways a Woman Can Get Hurt,† Jean Kilojoules asserts that â€Å"Male violence is subtly encouraged by ads that encourage men to be forceful and dominant, and to value sexual intimacy more than emotional intimacy' (422).What Kilojoules states is that men believe sex is more significant and they forget the sentimental value. It is easier for men to identify women as an object because they justify their violent behavior, and if they perceive a woman as an object they overlook the fact that they have feelings and emotions. Moreover, music is another factor that influences ideas of femininity particularly in a negative way. The lyrics used by rappers constantly degrade women by referring to them as â€Å"pitches† and â€Å"host†.Women using their bodies and sexuality to get what they want are what make these words accepta ble. In the passage â€Å"From Fly-Girls to Pitches and Host†, Joan Morgan writes â€Å"but many of the ways in which men exploit our images and sexuality in hip-hop is done with our permission and cooperation† (459). What Morgan states, is that females will be willing to expose their dies in a music video or allow rappers to degrade them simply to make money or get attention. There are countless songs that degrade women such as the song â€Å"Pitches anti chit but hoes and tricks. The name of the song is a phrase that is repeated multiple times throughout the song as if once were not enough. Tag, the artist of this song sings, â€Å"Got this bitchy named Tar, she let me buck her in the car, / Like Kim Sardinian she wane be star. † These lyrics suggest that women are good for sex, and deserve no respect. The worse part of the particular songs is that women listen to them or dance to hem at clubs because they enjoy the beat of the songs, but they are not conscio us of the demeaning lyrics.If women themselves listen to these songs it gives society the idea that they can refer to women in such a way. Due to the fact, because women are degraded in this manner, men believe that women are only good for sex and they fail to love them. Yet some readers may challenge my view by saying that popular culture has a minor influence on society's ideas of femininity. It's not so much the media but typical gender stereotypes that impact our ideas of femininity. Gender stereotyping begins t a young age, and little girls believe only girls should wear pink or only girls should play with Barbie's.Many hold stereotypes that women should look a certain way in order to be identified as a woman. People hold stereotypes that women must be classy, and not trashy. Indeed, stereotyping plays a significant role, but as we grow older it's not so much about the gender stereotypes but rather about what surrounds us on a daily basis that influences our ideas. Once you get older individuals can decide to ignore or put their gender stereotypes aside, but popular culture is something that Anton be ignored by any means.Popular culture is everywhere go, and without a doubt it's the primary factor that impacts our ideas. Furthermore, there are various steps that the popular culture can take in order to improve the perceptions of women. For instance, beauty pageants should have models that are more like the average woman who are not extremely thin. Beau' pageants should choose contestants based on their talents rather than their appearance. Advertisements should be appropriate, and not objectify women because they are human beings. They should eliminate advertisements where women are practically naked.In addition, they should not Photos the image of women in advertisements, but rather display the true image of the model. Women need to speak out about how degrading it is to be insulted in music by rappers, and the songs should be banned from the radio. Wome n should not agree to be degraded simply because they want to be in the music video of some popular rapper. Females must stand up for themselves in order to be treated with respect. In conclusion, even if We tried to ignore it the popular culture constantly influences our ideas of femininity.If the media was not so powerful society would have more realistic perceptions of femininity. Women should be valued for who they truly are because there's so much more to femininity then just a physical appearance or sex objectification. Females are sensitive individuals who have feelings and emotions, and deserve to be respected. A woman should not be judged if she does not look a certain way because nobody is perfect, and we all have flaws. Females are not Barbie dolls with a perfect little waist or the ideal face, they are real life individuals.

Organizational Culture Essay

Organizational Culture has been described as the shared values, principles, traditions, and ways of doing things that influence the way organizational members act. In most organizations, these shared values and practices have evolved over time and determine, toa a large extent, how things are done in the organization. This definition continues to explain organizational values, described as â€Å"beliefs and ideas about what kinds of goals members of an organization should pursue and ideas about the appropriate kinds or standards of behavior organizational members should use to achieve these goals. From organizational values develop organizational norms, guidelines, or expectations that prescribe appropriate kinds of behavior by employees in particular situations and control the behavior of organizational members towards one another. † The definition of culture implies three things. The culture is ‘perspective’, ‘descriptive’ and finally ‘shared’ within the organization. Research suggests that there are seven dimensions that describe and organization’s culture. Each of the seven dimensions (shown in exhibit 1) ranges from low to high, meaning it is not very typical of the culture (low) or is very typical of the culture (high). The seven dimensions of culture are: Attention to Detail. Outcome Orientation. People Orientation. Team Orientation. Aggressiveness. Stability. Innovation and Risk Taking. The culture of an organization can either be Strong or Weak. It is the culture, that sometimes influence the employees’ behaviors and actions. Strong Culture is said to exist where staff respond to stimulus because of their alignment to organizational values. In such environments, strong cultures help firms operate like well oiled machines, cruising along with outstanding execution and perhaps minor tweaking of existing procedures here and there. Research shows that strong cultures are those in which the key values are deeply held and widely shared and have a greater influence on employees than do weaker cultures. A â€Å"Strong† culture may be especially beneficial to firms operating in the service sector since members of these organizations are responsible for delivering the service and for evaluations important constituents make about firms. Research indicates that organizations may derive the following benefits from developing strong and productive cultures: †¢Better aligning the company towards achieving its vision, mission, and goals †¢High employee motivation and loyalty †¢Increased team cohesiveness among the company’s various departments and divisions. †¢Promoting consistency and encouraging coordination and control within the company †¢Shaping employee behavior at work, enabling the organization to be more efficient. However, in a strong culture, people do things because they believe it is the right thing to do, this often creates a state where people, even if they have different ideas, do not challenge organizational thinking, therefore, resulting in a reduced capacity for innovative thoughts. Most organizations have moderate to strong cultures; that is, there is relatively high agreement on what’s important, what defines â€Å"good† employee behavior, what it takes to get ahead, and so forth. However, it is also important to view what a weaker culture in an organization may yield at: An organization’s culture is often established by its top managers and it starts at the selection process. For instance, during the employee selection process, managers typically judge job candidates not only on the job requirements but also on how well they might fit into the organization. Further to that, the risk-taking appetite and irreverence to its competitors by the top managers paves the growth and action of an organization.

Philip Larkin’s Poetry Essay

In what ways does Larkin’s poetry show his attitude to death? In Philip Larkin’s poetry there is a profound sense of unease about death. Larkin, throughout his poetry, obviously contemplates the inevitable end that is death. In his poetry Larkin uses great observational skills, noting and writing about everyday circumstances in cinematic detail. With death, though, Larkin has nothing to observe. He cannot draw any precise conclusions about something that he has not directly experienced. I think, therefore, that Larkin shows a fear of death through his poetry, but also a deep fascination with it. I intend to show Larkin’s attitude to death through a number of his poems. In these poems Larkin certainly does show a fascination with death, but hopefully I will also show that Larkin’s attitude is not completely negative and that Larkin may see that death can have a redeeming end. The first poem from my selection that I will use is â€Å"ËÅ"Ambulances’, a poem where even the title suggests relation to death. In â€Å"ËÅ"Ambulances’ the emphasis is definitely placed upon death, the first line actually hints upon Larkin’s attitude to death. He begins by setting a very sombre image within the reader’s mind, saying â€Å"Closed like confessionals†Ã‚ ¦Ã¢â‚¬  An almost dooming phrase. The instant image given by this one line is dread. Most people dread going to confession and the thought of disclosing one’s secrets and sins can make it seem even more daunting. Larkin actually had no love for religion, in fact it was quite the opposite, and the comparison made between ambulances and confessionals can actually be seen as an attack on ambulances, showing that they are a front, concealing the inevitable. The comment upon the path that they take â€Å"†Ã‚ ¦they thread Loud noons of cities† may be used to represent death being everywhere, and like a thread it is woven into our lives. One may also see a religious reference within this phrase, showing that God who is supposedly with us always is now replaced with death looming over us. Even amongst the vibrancy and lively atmosphere of the city, perhaps even a rush hour, death still looms. We see Larkin’s great observation; he almost absorbs everything he sees, † †¦ giving back None of the glances they absorb. Light glossy grey, arms on a plaque.† Larkin sees as ambulances as representing death, which takes life, carrying it off but never returning it. He also shows not only his own fascination with death, but also the fascination all people have. Whenever people see the ambulance they immediately stare. The imagery of death as Light glossy grey, arms on a plaque and They come to rest on any kerb creates an impression upon the reader making them look at their own mortality and they realise that death is the one truth we all must encounter Larkin is bleakly honest when he says â€Å"All streets in time are visited†¦Ã¢â‚¬  This clearly shows that death is also common in all places and paints a picture for the reader to understand. â€Å"Then children strewn on steps or road, Or women coming from the shops Past smells of different dinners†¦Ã¢â‚¬  Larkin takes everyday chores experiences and relates them to death, showing how commonplace death is. The image of children being ‘strewn’ reflects the randomness of death. An image is evoked from the reader of bodies scattered and strewn after death has finally reached them. Even the youthful cannot escape death, children are susceptible. â€Å"†¦ see A wild white face that overtops Red stretcher blankets momently As it is carried and stowed† The use of enjambment rushes the reader through the lines and ives a sense of panic at the sight of this person being taken away. The use of the word â€Å"ËÅ"stowed’ shows that the body is just like an object being stowed away, an unimportant â€Å"ËÅ"thing’. Larkin then describes death as â€Å"the solving emptiness†. Life is seen as having such a meaningless nature and that death is there and â€Å"†¦lies just under all we do.† Death constantly threatens us in everything we do. This shows the fragility of human life. â€Å"And for a second get it whole, So permanent and blank and true.† This truth is inescapable, the repetition of ‘and’ drags out this whole meaning. The  utter truth is that death is forever, like the ambulances, we do not return. Larkin shows that people think of death, but when they see the truth that death holds it frightens them and they place it in the back of their minds. This is shown when he says â€Å"The fastened doors recede †¦Ã¢â‚¬  These fastened doors are the doors of the mind closed to what they don’t want to know, what they cannot possibly comprehend. As the body was stowed the people whisper â€Å"poor thing† but â€Å"at their own distress â€Å". These people do know that all streets in time are visited, including their own. When anything bad occurs, one naturally reacts by comparing the situation to one’s own life. We are sympathetic but naturally selfish. We all see death, including Larkin, as an image of a â€Å"..sudden shut of loss Round something nearly at an end†¦Ã¢â‚¬  The shut of the ambulance doors represents death closing in around life that is â€Å"nearly at an end†¦Ã¢â‚¬  Larkin’s language when he describes death as ‘something’ gives it anonymity life no longer has a source of meaning because Larkin sees death to be a stronger power which overpowers life. Death removes the uniqueness and identity of life; everyone comes to the same end. â€Å"And what cohered in it across The years, the unique random blend Of families and fashions there At least begin to loosen.† Larkin could be referring to the mix of genes we have inherited over the years and that death can loosen this blend. This also shows that we are ‘unreachable’ by anything but death. â€Å"The traffic parts to let go by†¦Ã¢â‚¬  This shows the traditional respect for the sick and the dead. This respect has been built up through the fear of death. I know that this is true to me, personally and obviously to Larkin also. Larkin ends with a very daunting cadence; â€Å"Brings closer what is left to come, And dulls to distance all we are. † This cadence, to me, seems very dramatic. It brings into perspective the whole theme of mortality. Larkin makes us think of how fragile and short life is. Larkin must really fear his own mortality. I suppose everyone fears death to  a certain extent, but not many people would care to, or even dare to contemplate what happens after death in as much detail as Philip Larkin. These thoughts must frighten him and anything to do with death and mortality must scare him. Another poem, that is not only relevant to the question, but is also on the same theme as ‘Ambulances’ is called ‘The Building’, the building being a hospital. Larkin describes the hospital as â€Å"Higher than the handsomest hotel† I think that this line is misleading and somewhat ironic, it is falsely attractive. It paints an almost positive picture of a hospital, but I feel that Larkin resents the height of it, after all, the bigger the building the larger the capacity it can hold. The building is â€Å"Like a great sigh out of the last century.† So this building is obviously a modern construction, a quite incongruous and disturbing building in it’s nineteenth century context. Larkin’s tone then changes to fear: â€Å"†Ã‚ ¦what keep drawing up At the entrance are not taxis; and in the hall As well as creepers hangs a frightening smell.† Larkin makes a reference to ambulances here also. He refers to them drawing up outside and the smell in the halls being â€Å"ËÅ"frightening’. He almost persomifies the smell by saying it hangs over them as if it were ready to pounce on any victim. He describes the waiting area and how the people’s faces are â€Å"restless and resigned† He obviously sees this as an area of tension evoking nervous reactions from those who await. He describes them as â€Å"†Ã‚ ¦humans, caught On ground curiously neutral, homes and names Suddenly in abeyance.† He is saying that in this building everyone is in the same boat. They are all â€Å"Here to confess the something has gone wrong.† This is similar to the idea of the confessionals in â€Å"ËÅ"Ambulances’. As I have said, this idea strikes unremitting fear. Each person is waiting to tell of how something has gone wrong with their bodies. Death is slowly violating them. â€Å"It must have been an error of a serious sort, For see how many floors it needs†Ã‚ ¦Ã¢â‚¬  He is amazed by the size of the building, or perhaps even scared by the size of the need for this building. After all men like to covet wealth but the need for this place is so great that the expense is necessary. â€Å"†Ã‚ ¦and how much money goes in trying to correct it†Ã‚ ¦Ã¢â‚¬  As a man is wheeled  past in old ward clothes the people all turn quiet, another aspect of death that was also shown in â€Å"ËÅ"Ambulances’. The people fear their mortality when they see death creep up on others. Larkin also relates to us how trapped he feels in the hospital and how distant the outside seems. â€Å"Far past these doors are rooms, and rooms past those And more rooms yet, each one further off And harder to return from†Ã‚ ¦Ã¢â‚¬  The distance between the outside and the rooms within the hospital seems greater than any physical distance, the freedom of the outside â€Å"†Ã‚ ¦out to the car park, free†Ã‚ ¦Ã¢â‚¬  seems to be slipping away like time, into the past, like a cherished memory: â€Å"†Ã‚ ¦outside seems old enough†. His desperation for this freedom is so immense that he even plots, in his mind, the route he took to the hospital. He states that we are lulled into a false sense of security and fears that he may never get out. â€Å"†Ã‚ ¦a touching dream to which we are lulled But wake from separately†Ã‚ ¦Ã¢â‚¬  We are â€Å"ËÅ"lulled’ into this false sense of security, this dream that we wake from â€Å"ËÅ"separately’, isolated and alone. He seems to pity those who, without realizing it, may have to stay for a longer period than they think, they â€Å"†Ã‚ ¦join the unseen congregations†Ã‚ ¦Old, young; crude facts of the only coin this place accepts†Ã‚ ¦Ã¢â‚¬  The only way of being accommodated here is to be sick. His attitude of inevitable death is shown again: â€Å"All know they are going to die Not yet, perhaps not here, but in the end, And somewhere like this.† He then goes on to describe life as a cliff we climb towards death and how death cannot be overcome. We may try to lighten the dark by bringing gifts, but they are merely wasteful gestures because death is so inevitable and final. Larkin’s attitude to death, here, sees it as totally negative, we also see this view in his poem ‘ The Explosion’, where Larkin takes the form of a third person, describing an incident which claims the lives of several miners in a rural community. Here, Larkin takes the role of a narrator and in this poem his view of death is more sanguine than it is in other poems. He does not express thoughts and feelings as much and I feel this shows how impersonal death really is. The poem has three distinct sections: before the explosion, the moment of the explosion and its aftermath. The first line  arouses a feeling of expectation; â€Å"On the day of the explosion’ We know that from the beginning of this poem that the explosion, and therefore death, is imminent. There is also a hint of Kinship that Larkin may have held for ‘the men in the pits’. He makes the men seem real by talking about ‘Fathers, brothers, nicknames, laughter’ which makes the reader feel the humanity of the men and therefore sympathise with them. These men were ordinary people with their own fears, even a fear of death. Even though these characters were killed in the explosion Larkin has tinged the ending of the poem with hope, because for an instant the love between the dead and their loved ones was so strong that it overcame death itself, allowing the loved one to see each other one last time. â€Å"Wives saw men of the explosion†¦Ã¢â‚¬  Larkin strangely endorses the idea of an afterlife even though he was an atheist. ‘The Explosion’ ends on an optimistic note. The final line tells us of how one of the dead miners shows ‘The eggs unbroken’. These ‘eggs’ are a symbol telling us not to lose hope, for even though we may die, nature and life will always carry on. It is set apart from the rest of the poem and can therefore be seen as a climax. So far, 1 have looked at Larkin’s dread, fear, curiosity and overall negative reaction to death. I think it is possible that Larkin may have also found a somewhat positive and redeeming aspect of death in his poem ‘An Arundel Tomb’. This poem tells of a dead earl and his wife the countess who were buried together in a tomb. Their tomb has become, through time, a tourist attraction because of the great likenesses formed from stone of their bodies. Larkin, again with his keen observational eye, looks upon statues and is shocked to find proof of hope and positivity. â€Å"It meets his left hand gauntlet, still Clasped empty in the other,. and One sees, with a sharp tender shock, His hand withdrawn holding her hand.† This chivalrous sight surprisingly hits a tender chord with Larkin, this is surprising due to his predominantly pessimistic views. Larkin also realises that the times of chivalry, knighthood and love are gone. Their love in this time has almost been changed to an untruth, yet is still has prevailed and lasted through time. Larkin looks at these deaths positively because he says, â€Å"†¦and to prove our Almost instinct, almost true : What will survive of us is love.† Larkin takes comfort in this as it reconciles and contrasts to his view that nothing exists after death. He previously described death as, â€Å"An endless meaningless.† Through looking at these poems, I found that throughout Larkin’s life, he tried and tried to find out what death was and what lay beyond it. Most of the time, we find that Larkin had a genuine fear of death, and he could not possibly surmise what lay beyond it. This could be due to his lack of faith and spirituality. For this reason I chose’ An Arundel Tomb’, so as to show that Larkin expressed some hope in death, love was the redeeming feature. Larkin discovered something in those statues that did go beyond death, and this is why he expressed it so beautifully in his last line: â€Å"What will survive of us is love.† Larkin’s poetry almost paths a journey he took through his life in discovering the truth about death. John Carey said that â€Å"Fear of death runs through the poems, and may seem irreconcilable with Larkin’s poised realism.† I have found that Larkin’s poetry is indeed interwoven with death throughout. This may be the case, but I also believe that Larkin found something redeeming in â€Å"ËÅ"An Arundel Tomb’ and that all of his works referring to death, were steps towards his own reconciliation with death.

Micro Manufacturing

ME 686: Micro-manufacturing Assignment 1 Study the effects of process parameters (speed, feed, depth of cut etc. ) associated with SPDT for manufacturing of micro lens let arrays. Also find out the ranges of these process parameters and values of optimal process parameters. Submitted by: Marmeek Kishor Kumar Kosambia (09010332) Submitted to : Dr. S. N. Joshi Date of Submission: 17/01/13 Introduction A microlens array is composed of a series of micro lens distributed in a regular pattern and has been usedin a wide range of photonic products.A  micro lens  is a small  lens, generally with a  diameter  less than a  millimetre  (mm) and often as small as 10 micrometers ( µm). The small sizes of the lenses means that a simple design can give good optical quality but sometimes unwanted effects arise due to optical  diffraction  at the small features. A typical micro lens may be a single element with one plane surface and one spherical convex surface to  refract  the light. Because micro lenses are so small, the substrate that supports them is usually thicker than the lens and this has to be taken into account in the design.More sophisticated lenses may use  aspherical  surfaces and others may use several layers of optical material to achieve their design performance. Since surface roughness affects the performance of the lens, one needs to generate finely machined surface with minimum roughness Single Point Diamond Turning machining is a technique which removes materials from a few microns to sub-micron level to achieve ductile mode machining on hard-to-machine materials such as electro less nickel plating, silicon, quartz, glass and ceramics with no subsurface defects.Such a machining process is able to achieve mirror surface finish of less than 10 nm and form error of less than 1um easily. If properly applied to a specific range of diamond turnable materials, the process is far superior to grinding and polishing where shape control is mo re difficult and processing time is longer. The selecting and optimization of machining parameters is one of the main factors that could influence the machining accuracy. The main machining parameters are tool feed rates, spindle speed and depth of cut.The tool feed rate is normally expressed in terms of either distance travelled by the tool per unit time (mm/min) or distance travelled per unit rotation (mm/revolution). It is most common to see the distance per revolution as it is directly related to the anticipated theoretical surface finish. For a given tool feed rate, larger the tool nose radius, lower the roughness and the better the optical surface finish. The surface quality depends to great extents on the material characteristics like: grain size, micro structure or crystal boundary, crystal uniformity and annealing procedures adopted. Casual selection of combination of machining parameters may affect the surface quality, so it is required to optimize the machining parameters before final SPDT process. Machining of aspheric surface is more complicated than spherical and flat surfaces because of complicated tool path and uneven material removal. To achieve required profile tool path should be optimized. Surface roughness with respect to variable Feed rate Feed rate is most important parameter and variation of this havea great impact on the surface finish. Theoretical surface finishdepends on feed rate and tool radius.Depth of cut 2 ? m andRPM 1000 kept constant and tool feed rate is varied from 0. 5? m/rev to 5. 0 ? m/rev. the results of the experiments are asfollows. From the above experiments, it is observed that the surface finish is going down as we reduce feed. The surface roughness is 54. 8 nm at feed 0. 5 ? m where the depth of cut is 2 ? m and 1000 RPM was maintained. It is investigated that although look of the surface was good but it is not of optical quality at these parameters. We have varied the depth of cut at feed rate of 0. 5. Surface rou ghness with respect to variable depth of cutFrom the above experiments, it is observed that the surface finish is depending on the depth of cut but its behavior is different. As we increase the doc from 1? m to 2 ? m the roughness decrease from 117 nm to 54 nm and again increase the roughness on of doc. Same is again repeated on 8 ? m doc. The surface roughness is 54. 8 nm at feed 0. 5 ? m/rev where the depth of cut is 2 ? m and 1000 RPM. But it is investigated that surface is not optical at these parameters, the surface quality was dull after 10 ? m doc and there no use of increasing the doc more than 10 ? m.From the above experiments, it is observed that the surface finish is depending on the depth of cut but its behavior is different. As we increase the doc from 1? m to 2 ? m the roughness decrease from 117 nm to 54 nm and again increase the roughness on of doc. Same is again repeated on 8 ? m doc. The surface roughness is 54. 8 nm at feed 0. 5 ? m/rev where the depth of cut is 2 ? m and 1000 RPM. But it is investigated that surface is not optical at these parameters, the surface quality was dull after 10 ? m doc and there no use of increasing the doc more than 10 ? m.Surface roughness with respect to variable RPM From the last experiment we have seen that the depth of cut 2 ? m giving the better surface. During this experiment feed rate 0. 5 ? m/rev and depth of cut remained unchanged and RPM varied from 800 to 4000, to get the further better surface on the work piece. Analysis of turned work piece at different RPM is carried out. Output result is shown in above table. By experiments we have seen that polycarbonate surface turned to the surface finish of below 25 nm, which is achieved at RPM 3000. A good surface finish is achieved at 800 RPM also but it is not economical.At RPM 1500 we have observed the star pattern on surface of PC. So, RPM 3000, Feed 0. 5 ? m/rev and depth of cut 2 ? m are the optimum parameters where optical surface is achieved. An empi rical formula is developed for predicting surface roughness of diamond turned polycarbonate at different turning parameters (feed rate, depth of cut and RPM). Empirical formula is derived as follows. Optimum turning parameter are suggested where the optical surface finish in obtained. Tool feed rate : 0. 5 ? m/revolution Depth of cut : 2 ? m RPM : 3000 Tool Path CompensationAnother study shows the greatest challenge lies in selecting the optimum combination of the process parameters to get the best surface quality. The parameters chosen for optimization are as: Spindle speed (SS), Feed rate (TFR), Depth of cut (DoC). Another parameter to optimize the machining is the tool path. The tool path compensation cycle starts with the definition of desired aspheric surface by the conic equation: It is observed that by modifying the tool path, profile error ofaspheric surface is significantly reduced. The comparison between aspheric figure error, before and after tool path compensation is giv en in Table-4.Conclusions: 1) Tool feed is the dominant parameter for surface roughness followed by the spindle rotational speed. Depth of cut shows minimal effect on surface roughness compared to other parameters. 2) Depth of cut is the leading parameter for peak to valley error, followed by spindle rotational speed. Feed rate does not have considerable effect on Pt. 3) Effect of depth of cut on Pt varies with spindle speed. However, for achieving good optical surface on the polycarbonate work piece, lower depth of cut is preferred. 4) Spindle rotational speed of 2000rpm, tool feed rate of1? m/rev and depth of cut of 2? are selected for precisemachining of polycarbonate. 5) The process of the optimization of tool path helps to optimize the machining process further.
