To what extent does disparity exist with the legalization of the birth Essay

To what extent does disparity exist with the legalization of the birth control movement in regards to poor and minority women in the United States - Essay Example But both prevented the spread of birth control by changing from a popular, participatory cause to a professional operation (Gordon, 1975). The most prominent activist is Margaret Sanger. She is known the founder of the birth-control movement in the United States was Margaret Sanger. She has witnessed the results of uncontrolled fertility, self-induced abortions, and high rates of infant and maternal mortality. Her experiences as a nurse and midwife led her to focus all her energy on the single cause of reproductive autonomy for women. She was convinced that there is a need for extensive information on contraception. She established information and advice centers that help women in safe, effective and female controlled contraceptive. She founded the American Birth Control League which later became Planned Parenthood Federation of America. That time issues regarding birth control and contraception was considered obscene and this results to continuous government harassment and closure of her shops. The Comstock Act which was passed in 1873 states that it is illegal to convey any information or devices that could be used f or preventing conception and defined it as obscene was used against Sanger in her advocacy (Battaglia, 1998). It was the government that controlled the access of poor women to birth control, sterilization and abortion for the most part of the 20th century. Primarily concerned about the maternal and infant mortality, the officials began to offer access to birth control centers but women have limited access. Birth control has difficulty in finding legislative support mainly because of the eugenic rhetoric and arguments used by supporters to promote them. There are four main groups that influenced the nature and delivery of the policies. First are the medical and social scientists that offer theories about the origins and characteristics of poverty and proposed solutions that involved the control of reproduction. Second are the leading health and welfare professionals that shaped public policy and influenced the nature of reproductive services. Third, the state and county officials who implemented public health and welfare policies shaped the delivery of reproductive services. Finally, the poor and minority women targeted by the programs responded to them. Factors such as sexuality, class and racial conflicts shaped the negotiations over reproductive control. The ability of women to control their sexuality in terms and conditions of motherhood are the center of debates about birth control. Class and racial background determines whether women will have access to reproductive health care. It was assumed by Policy makers and health and welfare professionals that poor single mothers in particular if they are African American, Hispanic, or Native American-lacked the ability to function properly as mothers and that they should be discouraged from further childbearing.

Midterm Paper about Concept for Nursing Theories course Term

Midterm about Concept for Nursing Theories course - Term Paper Example One of the main concerns of end-of-life care is the provision of quality care for end-of-life patients, which can be difficult to define for all involved stakeholders. For the society and many health care professionals, death is a sign of failure, and they are hesitant to allow people to naturally die from their illnesses. End-of-life care is critical, because nurses have to balance conflicting goals, such as helping patients and their families deal with the process of â€Å"letting go† and helping patients experience quality of life, while still living. End-of-life care will also contradict the goal of some patients and their families to extend life, even when illnesses are already terminal. This paper explores the concepts of end of life and end-of-life care and its definitions. It will determine the criteria for the concept of end-of-life, how it is addressed in literature, tools for measuring the concept, antecedents and consequences, and it will also provide three cases f or end of life care. Review of Literature End of Life Concept Karlsson and Berggren (2011) define end of life, as the phase of patient life, where â€Å"curative care is no longer possible† and survival time is considered â€Å"short† (p.374). Epstein (2010) is concerned of end of life’s implications on the quality of caring provided to dying patients. For him, the health care staff should be concerned of end of life’s implications to â€Å"dissatisfaction, conflict, and moral distress† (p.577). It is inferred that he defines â€Å"end of life† as a critical phase of care delivery, as the end of care looms. Reinke et al. (2010) agree with Epstein (2010) and affirm the necessity and urgency of the issue of quality care when end of life is concerned. Reinke et al. (2010) define end of life as the care response to the physical, emotional, social, and spiritual needs and concerns of dying people (p.753). End-of-Life Care Concept Lippincott Willi ams and Wilkins (2007) define end-of-life care in terms of palliative care, where the latter aims to prevent and relieve suffering and to advance the patient’s comfort and quality of life (p.3). There is no goal of hastening or delaying the patient’s death, and instead, stakeholders accept death as part of the natural cycle of human life (p.3). Poor (2001) also defines end-of-life care as a concept of palliative care, where it refers to the â€Å"comprehensive care of patients with a terminal illness who are nearing the end of life† (p.6). The World Health Organization (WHO) provides a more detailed definition of palliative care: â€Å"the active total care of patients whose disease is not responsive to curative treatment† (as cited in Poor, 2001, p.6). Some of the important goals of palliative care are to control pain and to respond to the psychological, social, and spiritual needs of the patient (Poor, 2001, p.6). The WHO provides the following characte ristics of palliative care: 1) Life and death are normal processes; 2) Death is not delayed or encouraged; 3) Pain control and control of other upsetting symptoms are important; 4) The spiritual and psychological components of care are included in the care plan; 5) There is a support system for patients to live a quality and active life; 6) and there is also support system for the family of the dying patient, so that the former can cope with the upcoming realities of death (as cited in Poor

Neonatal Respiratory Distress Syndrome: Causes and Effects

Neonatal Respiratory Distress Syndrome: Causes and Effects Shalyn Bauer Neonatal respiratory distress syndrome or (NRDS) occurs when a newborn babys lungs are not fully developed. This is often found in premature babies, however there is the occasional case where the baby is not premature. This disease is mainly caused by the lack of a substance called surfactant. Surfactant is a slippery substance made up of a mixture of lipids and proteins that is secreted into the fluid lining of the alveolar space by epithelial type II cells (ScienceDirect). This substance helps fill air in the lungs and keep the air sacs from collapsing. Surfactant usually starts to produce between week 24 through 28 and by week 34 there is enough produced for an infant to breathe normally. This is why a baby born prematurely may not have enough of this substance and have lung problems and difficulty breathing. Babies who are not premature but have NRDS can be caused by the mother having diabetes or poor lung development. Other risk factors include carrying twins or triplets or reduced blood flow during delivery. In a rare case, there may be a problem with a gene which can affect lung development. According to the article Neonatal respiratory distress syndrome, Its estimated half of all babies born before 28 weeks of pregnancy will develop NRDS. This has recently gone down due to the fact that a mother can be given a steroid during premature labor. If a premature delivery is expected, a mother can receive corticosteroids which speed up lung production and production of surfactant. NRDS displays symptoms that can be noticed right after being born. For example, a baby with this disease may have a bluish tint to their skin, flaring of nostrils or give off a grunting sound while breathing. In some cases a baby may not experience symptoms right after birth. It can take up to 24 hours before you can tell. Doctors how believe a child may have NRDS will order blood tests to measure the amount of oxygen in the blood and to rule out infections that could cause these symptoms. A doctor will also order a chest X-ray to look over the lungs. A pulse oximetry test, which is a sensor attached to the babys finger, ear or toe to measure how much oxygen is being absorbed into the blood. An infant who is diagnosed with NRDS will be admitted into a neonatal intensive care unit. They will provide the infant with warm moist oxygen and will be monitored closely to ensure the infant will not receive too much oxygen. An infant can be given artificial surfactant which is put in the airway to help restore normal lung function. An infant can also be put on a ventilator to provide extra breathing support. Without proper oxygen intake, a babys organs will not function properly. This is why treatment is crucial when a baby is first diagnosed. The treatment varies based on how severe the case may be. It is said that receiving consistent prenatal care and avoiding smoking, drugs and alcohol can help reduce the risk of premature delivery. There are some complications that come along with NRDS. This disease can be fatal in some cases. According to the article, Neonatal respiratory distress syndrome In more severe cases theres a risk of further problems. These can include scarring to the lungs, leading to longer-term breathing problems. Theres also a risk of brain damage, which may result in problems such as learning difficulties. Complications vary based on the severity of the case. Every baby is different and will experience different complications from the disease. NRDS is a scary diagnose for parents to hear, however the majority of cases can be successfully treated. Works Cited   Ã‚   Neonatal Respiratory Distress Syndrome. MedlinePlus Medical Encyclopedia.

Kabuo Assumed Guilty Because of Japanese Heritage in Snow Falling on Cedars by David Guterson :: Snow Falling Cedars David Guterson Essays

Kabuo Assumed Guilty Because of Japanese Heritage in Snow Falling on Cedars by David Guterson In the novel, Snow Falling on Cedars by David Guterson, Kabuo Miyamoto is arrested for murder without any substantial evidence. He was charged with a crime he did not commit. He was accused based strictly on his race. Kabuo’s trial was unfair because there was racial conflict with the Japanese following World War II. The racial conflict with Japanese-Americans began when the Empire of Japan attacked Pearl Harbor. On December 7, 1941, the Empire of Japan launched a surprise attack on Pearl Harbor, a military naval base located in the state of Hawaii. â€Å"Behind them they left chaos, 2,403 dead, 188 destroyed planes, and a crippled Pacific Fleet that included 8 damaged or destroyed battleships† (â€Å"Attack† 1). The next day, President Franklin D. Roosevelt declared war on the Empire of Japan. The fear that resulted from the attack on Pearl Harbor caused many white Americans to hate the Japanese-Americans. Many Japanese were accused of being spies and were arrested without proof. â€Å"Rabid anti-Japanese American racism surfaced the first days after Pearl Harbor. The FBI and the military had been compiling lists of "potentially dangerous" Japanese Americans since 1932, but most were merely teachers, businessmen or journalists† (Thistlethwaite 1). In February of 1942 , all of the Japanese on the West Coast of the United States were sent to internment camps. Japanese Internment Camps were established to keep an eye on everyone of Japanese decent. The internment camps were based on an order from the President to relocate people with Japanese Heritage. This meant relocating 110,000 Japanese people. â€Å"Two thirds of these people were born in America and were legal citizens, and of the 10 people found to be spying for the Japanese during World War II, not one was of Japanese ancestry† (Friedler 1). Thus, there was no reason for these internment camps, but people do irrational things when driven by fear. In theinternment camps, many of the Japanese became sick or even died because of lack of nourishment in the food provided at these camps. The conditions in the internment camps were awful. One of the internment camps, Manzanar, was located to the west of Desert Valley in California. â€Å"Manzanar barracks measured 120 x 20 feet and were divided into six one-room apartments, ranging in size from 320 to 480 square feet.

Nigella Lawson and Jamie Oliver Essay

Both Nigella Lawson and Jamie Oliver are well recognized TV chefs, however both use spoken language in very different ways, while interacting with their audience. For example Nigella’s language is more sophisticated and formal whereas Jamie’s language is more casual and informal. While there are many language differences between each of these chefs, there are also many similarities. Jamie Oliver was brought up in Essex, where people usually are open minded and sociable. When he does his openings he usually uses phrases like â€Å"Hey guys† & â€Å"Hello lovely people†, this friendly approach to the audience makes him more connected to people all around the world who watches his TV programmes like Jamie’s 15 minutes meals. Nigella in the other hand was born in wandsworth London and was brought up in a self-established and well educated family. She uses sophisticated language and she doesn’t usually has a warm greeting like Jamie’s inste ad she gets straight to the point like â€Å" this salad† , which suggest that the main focus for her is the food she is cooking. Jamie Oliver uses friendly gestures from beginning to the end. He starts usually with â€Å"hey guys† which automatically brings a friendly feeling towards the audience. This creates Jamie as an friendly and approachable. He uses informal speech while talking to the audience making them feel connected to him and making them more focused on what he is trying to say. While he is doing some action like smashing a potato he doesn’t usually say â€Å"smash the potato† but instead he uses â€Å"bash the hell out of it† which in sense is using onomatopoeia which makes it more exciting and simple to understand. Jamie does use this quiet often and also uses slang languages which is more appealing to teen audiences and it also sounds very relaxed and laid back. Nigella uses words like â€Å"lethally and fierce chilli† which is related to some type of quick and snappy. It shows how quick the chilli flavour hits you and how strong the hotness is in the ingredie nt. This may make the audience feel that the chilli is very powerful. The word lethally and fierce are common words to describe chilli. Nigella also uses long pauses while saying the word chilli, while she has long pauses its usually for gestures to take place for the pause moments. Language used by Nigella and Jamie both of them use semantic fields of cookery throughout their programme. They use this to add come kind of impression to their audience while differentiating to which category their food falls into. Jamie uses jargon throughout his programme and he uses it  more frequently as he is well connected to his viewers and others(who) already know him as an casual informal chap from down the street. In the other hand nigella creates huge focus on her jargons to make sure that what are good and what are bad in the food, however in my opinion she sticks to more difficult words what only small proportion of people could understand again implementing she was well educated and was raised in higher class family. Other factors of her that we could also state is being flirtatious with the audience which could make her more appealing to men audiences and making her more likeable and getting more likes and views. She uses words like â€Å"plumcious beauties† which have more impact on male audience then female audience. In conclusion, I believe that Nigella Lawson and Jamie Oliver both use effective language in there spoken responses. This is because they want to encourage their target audience that everyone can cook even if it’s more difficult or something easy. Nigella uses more sophisticated and formal language, which is mostly based for a more upper classed audience and jamies uses informal language and slang which makes him more reliable to teenagers who don’t want any hassel and just want quick and simple way to make good food. Overall Nigella and Jamie have their own ways and uses different language techniques to engage and persuade the audience that they have the most successful food methods and recipes, which has been proven as these chefs have been well known on TV newspapers and magazines.

Manager’s Function, Skills and Role Essay

This page investigates the skills, roles and functions of Management. For any organisation to achieve the goals it has established and be successful it needs managers to correctly implement and understand the functions, skills and roles involved in the managerial process. How these are applied will vary depending on what level of management a particular manager is involved in (high, middle, low) and the organisation. Regardless of these two factors all management decisions focus on the efficient and effective use of resources for the benefit of the organisation, in the direction of its desired goals and/or objectives. The Functions of Management The four functions of management are planning, organising, leading and controlling (Davidson et al, 2009. p.13). Planning involves reviewing the current situation and generating a plan that will allow the organisation to meet its established goals and objectives (Selley, 2009). This could entail generating a plan to increase profit and detail how this will be achieved (focus on capturing a larger market share or perhaps moving into a new market). Correct planning ensures there is a degree of focus, while also providing a structured timeline that relevant stakeholders can adhere too. The second stage is organising, this is where management prepares for the task ahead by delegating resources and responsibilities, as efficiently and effectively as possible (Pakhare, 2011). During this stage management would consider the different departments and divisions within its organisation and provide authority and tasks as necessary. An organisation that wants to increase its profit might use the organising stage to outline the roles of marketing (investigate and promote new market share) and separate these from the accounting department (assess the viability by calculating projected sales and expenses) while also ensuring they all have the necessary resources to complete the work. Davidson et al. defines leading as the process of getting members to work together for a common interest (2009. p.14). Leading requires a manager to have a positive influence on people while also inspiring them to complete their jobs (making this vital in low-middle management), this in turn improves their job performance through a positive work environment (Expert Manage, 2011). It is important to establish this positive environment to ensure that deadlines set in the initial planning stage can be met and resources are not being wasted. The final stage in the function of management is controlling, this stage is important in the establishment of performance standards and ensuring these standards are adhered too while also taking corrective actions against deviation. If for example deadlines are not being met the manager should investigate, if they this was due to incorrect original estimates relating to the workload required, the manager could increase staffing for the particular project. Management has been described as a social process involving responsibility for economical and effective planning & regulation of operation of an enterprise in the fulfillment of given purposes. It is a dynamic process consisting of various elements and activities. These activities are different from operative functions like marketing, finance, purchase etc. Rather these activities are common to each and every manger irrespective of his level or status.Different experts have classified functions of management. According toGeorge & Jerry, â€Å"There are four fundamental functions of management i.e. planning, organizing, actuating and controlling†. According to Henry Fayol, â€Å"To manage is to forecast and plan, to organize, to command, & to control†. Whereas Luther Gullick has given a keyword ’POSDCORB’ where P stands for Planning, O for Organizing, S for Staffing, D for Directing, Co for Co-ordination, R for reporting & B for Budgeting. But the most widely accepted are functions of management given by KOONTZ and O’DONNEL i.e.Planning, Organizing, Staffing, Directing and Controlling.| For theoretical purposes, it may be convenient to separate the function of management but practically these functions are overlapping in nature i.e. they are highly inseparable. Each function blends into the other & each affects the performance of others. 1. Planning It is the basic function of management. It deals with chalking out a future course of action & deciding in advance the most appropriate course of actions for achievement of pre-determined goals. According to KOONTZ, â€Å"Planning is deciding in advance – what to do, when to do & how to do. It bridges the gap from where we are & where we want to be†. A plan is a future course of actions. It is an exercise in problem solving & decision making. Planning is determination of courses of action to achieve desired goals. Thus, planning is a systematic thinking about ways & means for accomplishment of pre-determined goals. Planning is necessary to ensure proper utilization of human & non-human resources. It is all pervasive, it is an intellectual activity and it also helps in avoiding confusion, uncertainties, risks, wastages etc. 2. Organizing It is the process of bringing together physical, financial and human resources and developing productive relationship amongst them for achievement of organizational goals. According to Henry Fayol, â€Å"To organize a business is to provide it with everything useful or its functioning i.e. raw material, tools, capital and personnel’s†. To organize a business involves determining & providing human and non-human resources to the organizational structure. Organizing as a process involves: * Identification of activities. * Classification of grouping of activities. * Assignment of duties. * Delegation of authority and creation of responsibility. * Coordinating authority and responsibility relationships. 3. Staffing It is the function of manning the organization structure and keeping it manned. Staffing has assumed greater importance in the recent years due to advancement of technology, increase in size of business, complexity of human behavior etc. The main purpose o staffing is to put right man on right job i.e. square pegs in square holes and round pegs in round holes. According to Kootz & O’Donell, â€Å"Managerial function of staffing involves manning the organization structure through proper and effective selection, appraisal & development of personnel to fill the roles designed un the structure†. Staffing involves: * Manpower Planning (estimating man power in terms of searching, choose the person and giving the right place). * Recruitment, selection & placement. * Training & development. * Remuneration. * Performance appraisal. * Promotions & transfer. 4. Directing It is that part of managerial function which actuates the organizational methods to work efficiently for achievement of organizational purposes. It is considered life-spark of the enterprise which sets it in motion the action of people because planning, organizing and staffing are the mere preparations for doing the work. Direction is that inert-personnel aspect of management which deals directly with influencing, guiding, supervising, motivating sub-ordinate for the achievement of organizational goals. Direction has following elements: * Supervision * Motivation * Leadership * Communication Supervision- implies overseeing the work of subordinates by their superiors. It is the act of watching & directing work & workers. Motivation- means inspiring, stimulating or encouraging the sub-ordinates with zeal to work. Positive, negative, monetary, non-monetary incentives may be used for this purpose. Leadership- may be defined as a process by which manager guides and influences the work of subordinates in desired direction. Communications- is the process of passing information, experience, opinion etc from one person to another. It is a bridge of understanding. 5. Controlling It implies measurement of accomplishment against the standards and correction of deviation if any to ensure achievement of organizational goals. The purpose of controlling is to ensure that everything occurs in conformities with the standards. An efficient system of control helps to predict deviations before they actually occur. According to Theo Haimann, â€Å"Controlling is the process of checking whether or not proper progress is being made towards the objectives and goals and acting if necessary, to correct any deviation†. According to Koontz & O’Donell â€Å"Controlling is the measurement & correction of performance activities of subordinates in order to make sure that the enterprise objectives and plans desired to obtain them as being accomplished†. Therefore controlling has following steps: * Establishment of standard performance. * Measurement of actual performance. * Comparison of actual performance with the standards and finding out deviation if any. * Corrective action. Management Skills While a solid grasp of management functions is important management should also have a sound skill base, a report by Hay’s Group suggests this is a weak area for most individuals in management and is one of the biggest threats to business success (Financial Advisor, 2007). These skills include but are not limited to technical, interpersonal and conceptual skills. â€Å"Technical skills are those necessary to accomplish or understand the specific work being done in an organisation,† (Davidson et al, 2009. p.19). These technical skills are used mostly at the lower levels of management and are obtained through experience and training. An example of technical skills could be introducing and teaching a new accountant the accounting system used by the firm. Interpersonal skills focus on the ability to work with, motivate and communicate with other people (Hahn, 2007). This skill is very important for managers to create a strong relationship between both individuals and groups within the organisation (Dale, 2008, p.121) this will ensure that there is trust and respect between these parties, allowing tasks to be completed effectively and efficiently. The final core skill of management is conceptual thinking, this is the ability to consider a situation both abstractly and logically in order to come to the correct decision based on internal and external environments (Griffin, 2011. p.179). Globalisation has made this skill extremely important for managers (especially those in high-level positions), as they must be able to break-down and analyse information to make immense decisions that potentially have a worldwide impact. Management Roles Through numerous managerial roles the skills discussed above are put into practice. Mitzberg’s observations and research suggest that a manger’s role can be split into ten roles and three categories; interpersonal (management through people), informational (management through information) and decisional (management through action) (Daft and Marcic, 2010. p.17). Interpersonal roles naturally form an important part of being a manager and relate to activities involving other people. Some interpersonal tasks could involve being a figurehead and speaking at important organisation ceremonies, motivating employees through leadership or serving as a liaison between different departments (Davidson et al, 2009. p.18). Informational roles are focused on the processing of information, this could include seeking out information while also analysing and monitoring for relevant changes that apply to the organisation, communicating information to your co-workers or being a spokesperson on behalf of the organisation (MindTools, 2011). Informational roles require quick and thorough processing of information and resilience to information overload. The final category is decisional which requires decisions to be made using the information provided. This could require developing innovate ideas, serving as a mediator to resolve conflict, allocating resources within the organisation and negotiating on the organisations behalf. A manager involved in a decisional role must have strong problem solving abilities, be able to prioritise and have good negotiation skills. Reference List Daft, R. Marcic, D.

Electronic Voting Machine Essay Example

Electronic Voting Machine Essay Example Electronic Voting Machine Essay Electronic Voting Machine Essay International Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 A Preview on Microcontroller Based Electronic Voting Machine Diponkar Paul and Sobuj Kumar Ray, Member, IACSIT Abstract- Voting is most pivotal process of democratic society through which people determine it’s government. Governments around the world are increasingly considering the replacement of traditional paper-based voting schemes with electronic voting systems. Elections of Bangladesh are conducted most exclusively using electronic voting machines developed over the past three years. In this paper we describe the design, construction and operation of a digital voting machine using a microcontroller profoundly. Again we also portray counting system of votes, market survey and cost analysis. Index Terms- Voting system, atmega16l microcontroller, voting analysis, security of EVM. I. INTRODUCTION Voting is a crucial device to reveal the opinion of a group on an issue that is under consideration. Based on the promise of greater e? iency, better scalability, faster speed, lower cost, and more convenience, voting is currently shifting from manual paper-based processing to automate electronic-based processing. The term â€Å"electronic voting† characteristically depicts to the use of some electronic means in voting and ensure the security, reliability, guarantee and transferency[1],[2]. Now a day the wide range of application of voting inclu de its use in reality student body elections, shareholder meetings, and the passing of legislation in parliament. Perhaps the most important, in? ential, publicised, and widespread use of voting is its use in national elections. Compared to its traditional paper-based counterpart, electronic voting is considered to have many greater potential bene? ts. These bene? ts include better accuracy by eliminating the negative factor of human error, better coverage for remote locations, increased speed for tally computation, lower operational cost through automated means, and the convenience of voting from any location Whether or not electronic voting is a necessary replacement for the traditional paper-based method, it is irrefutable that the conduct of voting as been shifting to the use of electronic medium. To date, electronic databases are used to record voter information, computers are used to count the votes and produce voting results, mobile devices are used for voting in interactive television shows, and electronic voting machines have been used in some national elections. Generally, the term â€Å"electronic voting† refers to the de? nition, collection, and dissemination of people’s opinions with the help of some machinery that is more or less computer supported. Despite Manuscript received August 15, 2012; revised October 12, 2012. The authors are with the Department Electrical and Electronic Engineering, World University of Bangladesh, Dhaka, Bangladesh (e-mail: [emailprotected] com, [emailprotected] edu. sg) the transition from traditional paper-based systems to electronic medium, the purpose and requirements for voting remain. Voting is a decision making mechanism in a consensus-based society and security is indeed an essential part of voting. The critical role in determining the outcome of an election, electronic voting systems should be designed and developed with the greatest care. However, a number of recent studies have shown that most of the electronic voting systems being used today are fatally defective [3], [4], [5] and that their quality does not match the importance of the task that they are supposed to carry out. Flaws in current voting systems, which were discovered through testing and other analysis techniques, have stimulated a number of research efforts to mitigate the problems in deployed voting systems. These efforts focused on ameliorating security primitives, such as the storage of votes [6], [7] and auditing [8], and on formally assessing and making procedures more effective [9], [10]. Finally, the standards that set the functional and performance requirements against which the systems are developed, tested, and operated have often been found to be inadequate [11], [12], [13]. Among the reasons for concern, critics include vague and incomplete security guidelines, insufficient documentation requirements, and inadequate descriptions of the configuration of commercial software. An electronic voting machine has been designed by a microcontroller for which the code is written in assembly language. Various code protection schemes specified by the manufacturer of the microcontroller are used to prevent inadvertent or deliberate reading and reproduction of the code contained in the microcontroller. The election data contained in the EEPROM of the microcontroller can download into a central computer for tabulations. The security of data in this computer is enforced by generating digital signatures for each data file created. This process makes it impossible for anyone to substitute wrong or deliberately altered data files at any intermediate stage between the capturing of voter’s intent by the machine and the final results tabulations. Prior to the election, all con? guration data is set up on the counting server. The con? guration is then transferred to the ballot-box server. Con? guration data include: candidate names, polling station identity, and a list of barcodes. During the voting period, voters are authenticated as per the traditional paper-based voting, and asked whether they wish to vote electronically or use the traditional paper-based method. A voter choosing to use the traditional paper-based method proceeds by being given a ballot paper, casting the vote on the ballot paper, and placing the ballot paper in a ballot-box. On the other hand, a barcode is chosen at random and is given to the voter choosing to use eVACS. Voter authorisation on the electronic voting booth computer is by 185 DOI: 10. 7763/IJIEE. 2013. V3. 295 International Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 using the barcode. The electronic voting booth computer communicates the barcode to the ballot-box server for validation and to inform that the voting process is initiating. Upon validation of an invalid barcode, the ballot-box server returns an error message to the voting booth computer. Otherwise, the ballot-box server returns the equivalent of a ballot-paper containing the names of candidates to the voting booth computer. The voter may select the candidates in a particular preference ordering, and restart or complete their selection afterwards. The selection is displayed on the screen forcon? rmation, and the voter is allowed to change or con? rm their selection. The voting booth computer returns a warning given invalid selection or informal vote, however casting invalid or informal vote is allowed. The voter con? ms the selection by using the barcode, and both the vote and a log of key sequence pressed are then communicated to the ballot-box server. The ballot-box server checks that the same barcode is used to initiate the server counts the votes, and produces a voting result. II. HARDWARE DEVELOPMENT OF ELECTRONIC VOTING MACHINE Fig. 1. Block diagram of digital voting system Fig 2. Circuit diagram of the digital voting system A. Circuit Description The high level digital voting machine built with ATmega16 Micro controller. The Micro controller port D uses for LCD display and port C. (pin 22) uses for voting power or presiding officers button. The candided button input from Port C. 1 – C. 4 (pin 23 to 26; 4 candided). The output LED and buzzer uses Micro controller port C. 5 and C. 6. The LCD backlight also connected to port C. 7 via a transistor. At the starting of voting the election commission offices setup the machine at the centre. Then power on the switch and sealed it that nobody can power off. The presiding officer identifies the original voter of that particular area and pushes the voting power button. The voting power LED glow then and continue it until once press the candided buttons. The voter then goes to the secret room where Voting unit placed and press button beside his candided symbol. Voter can watch success of voting by glowing confirmation LED and beep indication. The presiding officer can also hear beep sound watch a confirmation LED. Same time the voting power goes down and nobody can vote again. Mainly when presiding officer press voting power button, Micro controller start scanning from pin 23 to pin 26. When get response from a specific pin, increase the counter one of that candided and stop scanning. So it is not possible to voting twice or more. All the counter result store at Micro controller EEPROM. When the voting is under process it will showed at display â€Å"Voting under Process†. At the end of voting we need to know result. Then election commission or presiding officer presses the secret key (password). Now the Micro controller shows the result and supply the power to LCD backlight that it illuminated. If it needs to return voting process again one should press another secret key. There uses a transistor to operate buzzer and confirmation LED with proper current. There also uses a voltage regulator (7805) to supply 5v continuously. Here uses a dry cell 9V battery as power source. The power consumption of the system is very low (50mW150mW varying). After collected data and need erase recorded data from EEPROM just broken the sealed on power button and power off the system. Now the system is ready for next election. This measurement System includes the following components: Voting Unit Control Unit Confirmation Unit Display Unit (LCD) Power Supply Unit B. Voting Unit Fig. 3. Output circuit diagram of the digital voting system Fig. 4. Voting 186 International Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 Fig. 5. Confirmation unit In this Voting unit we have been used five button switch and five 2. 2K? resister which connected to the five button switches. C. Buzzer A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical or piezoelectric. Typical uses of buzzers and beepers include alarm devices. These devices are output transducers converting electrical energy. As power is applied this mechanical device will energize and by doing so interrupt the power source and the cycle continue until the power is removed. The frequency of oscillation is strictly dependent on mechanical inertia. The piezo buzzer produces sound based on reverse of the piezoelectric effect. The generation of pressure variation or strain by the application of electric potential across a piezoelectric material is the underlying principle. These buzzers can be used alert a user of an event corresponding to a switching action, counter signal or sensor input. They are also used in alarm circuits. The buzzer produces a same noisy sound irrespective of the voltage variation applied to it. It consists of piezo crystals between two conductors. When a potential is applied across these crystals, they push on one conductor and pull on the other. This, push and pull action, results in a sound wave. Most buzzers produce sound in the range of 2 to 4 kHz. The Red lead is connected to the Input and the Black lead is connected to Ground. D. Light Emitting Diode (LED) A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. When a light-emitting diode is forward-biased (switched on), electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. LEDs are often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, 187 mproved robustness, smaller size, and faster switching. LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamp sources of comparable output. Light-emitting diodes are used in applications as diverse as replacements for aviation lighting, automotive lighting (in particular brake lamps, turn signals, and indicators) as wel l as in traffic signals. LEDs have allowed new text, video displays, and sensors to be developed, while their high switching rates are also useful in advanced communications technology. Infrared LEDs are also used in the remote control units of many commercial products including televisions, DVD players, and other domestic appliances E. Controller Unit A control unit in general is a central part of the machinery that controls its operation, provided that a piece of machinery is complex and organized enough to contain any such unit. One domain in which the term is specifically used is the area of computer design. In this work Microcontroller ATMEGA 16L is used as the controller unit which controls the sensed signal. A single highly integrated chip that contains all the components comprising a controller. Typically this includes a CPU, RAM, some form of ROM, I/O ports, and timers. Unlike a general-purpose computer, which also includes all of these components, a microcontroller is designed for a very specific task to control a particular system. As a result, the parts can be simplified and reduced, which cuts down on production costs. Microcontrollers are sometimes called embedded microcontrollers, which just mean that they are part of an embedded system that is, one part of a larger device or system. F. Power Supply Unit Power supply is a very important part of electronic circuit this circuit required fixed +5 V supply so to fix this voltage we needed voltage regulator. In this work used 7805 Voltage regulator which output fixed +5 volt. A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions. There are two types of voltage regulators: linear and switching. A linear regulator employs an active (BJT or MOSFET) pass device (series or shunt) controlled by a high gain differential amplifier. It compares the output voltage with a precise reference voltage and adjusts the pass device to maintain a constant output voltage. G. Display Unit Display device shown the result of the measuring instrument. A observer can see the result and observe the temperature of electrical machine. In this work we used a 216 character LCD (LM016L) display. A liquid crystal display (LCD) is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals. H. Printed Circuit Board A printed circuit board, or PCB, is used to mechanically International Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. It is also referred to as printed wiring board (PWB) or etched wiring board. A PCB populated with electronic components is a printed circuit assembly (PCA), also known as a printed circuit board assembly (PCBA). Printed circuit boards are used in virtually all but the implest commercially produced electronic devices. PCBs are inexpensive, and can be highly reliable. They require much more layout effort and higher initial cost than either wire wrap or point-to-point construction, but are much cheaper and faster for high-volume production; the production and soldering of PCBs can be done by automated equipment. Much of the electronics industrys PCB design, assembly, and quality control needs are set by standards that are pu blished by the IPC organization.

SOFTWARE DEVELOPMENT FOR ELECTRONIC VOTING MACHINE Flowchart of Program: user. In both of the systems that we analyzed, we found major security vulnerabilities that could compromise the confidentiality, integrity, and availability of the voting process. The results of our study suggest that there is a need for a drastic change in the way in which electronic systems are designed, developed, and tested. Researchers, practitioners, and policy makers need to define novel testing approaches that take into account the peculiar information flow of these systems, as well as the combination of computer security mechanisms and physical procedures necessary to provide a high level of assurance. Electronic voting software is not immune from security concerned. Here we describe Hack-a-vote, a simplified DRE voting system that we initially developed to demonstrate how easy it might be to insert a Trojan horse into a voting system. In case of a discrepancy, there either must be a row with the fresh random number. But without a mark of the voter or the alignment information on the ballot and on the receipt must differ. The proof consists either of a row containing the fresh random number but no mark without revealing which row this is or the proof consists of the two differing alignment bar codes without showing the mark at all. After the publication of the receipts the situation is analogous to the paper based schemes above as the voter possesses a correct receipt as electronic evidence. In addition to using unforgivable receipts with a special paper one can assume a trusted printer containing a chip card this printer could have the chip card and print the signature to the receipt. Having two in dependent ways to proved receipt to be not a forgery is a big advantage. REFERENCES D. Balzarotti, G. Banks, M. Cova, V. Felmetsger, R. A. Kemmerer, W. Robertson, F. Valeur, and G.

RESULTS AND ANALYSIS This work contributed to three very basic research questions arising: in the context of verifiable elections. First, we discussed the problem of keeping ballot secrecy to a certain extent in the case of a corrupted doting machine or voting authority. Our contribution to this is an approach where all secret information is encapsulated in the voting machine. Second, we considered the attack of receipt stealing and manipulation of the corresponding votes. Here we proposed a novel approach of linking all receipts by a hash chain such that each single receipt guards the integrity of all receipts issued previously. Together with a display in the polling place this approach shortens the time window in which an adversary can perform the ballot stealing attack without almost zero risk. Third, we discussed in detail the possibility of contesting an election based on the evidence provided by the verifiable election scheme. We compared the situation for Bingo Voting to the evidence provided by paper based schemes. We shortly sketched an approach to prove an error or a manipulation in the voting booth without violating ballot secrecy. However, this was only a proof of concept and for a practical application the usability of this approach needs to be further improved. V. CONCLUSION As part of these exercises, we devised a testing methodology, developed new tools that are specifically tailored to the security analysis of these systems, and learned a number of lessons, all of which should be of use to other 189 International Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 [12] M.

Free Essays on The Tyger† Free Essays on The Tyger† Patricia Sayles ENGL 1302 March, 13 2004 The Tyger is perhaps, apart from the words to the hymn Jerusalem the best known of all Blake’s work. As the contrary poem to The Lamb, The Tyger is straight from the heart of the Songs of Experience. The Tyger it is a poem that addresses our constant struggle to decode, interpret and master the world around us, as well as a satire on the ways we attempt to carry this task out, I prefer to interpret The Tyger as a poem that addresses the creation of evil in the world. The Tyger is a poem full of rich, powerful imagery and sound. We will address Blake’s use of the variations within it as a mechanism used to communicate to the reader this attack on the Establishment. Metrically, The Tyger is principally trochaic which creates a forceful drum-beat reflecting the power of both the tyger and its Creator.

Example of a Permutation Test

Example of a Permutation Test One question that it is always important to ask in statistics is, â€Å"Is the observed result due to chance alone, or is it statistically significant?† One class of hypothesis tests, called permutation tests, allow us to test this question. The overview and steps of such a test are: We split our subjects into a control and an experimental group.  The null hypothesis is that there is no difference between these two groups.Apply a treatment to the experimental group.Measure the response to the treatmentConsider every possible configuration of the experimental group and the observed response.Calculate a p-value based upon our observed response relative to all of the potential experimental groups. This is an outline of a permutation.  To flesh of this outline, we will spend time looking at a worked out example of such a permutation test in great detail. Example Suppose we are studying mice.  In particular, we are interested in how quickly the mice finish a maze that they have never encountered before.  We wish to provide evidence in favor of an experimental treatment.  The goal is to demonstrate that mice in the treatment group will solve the maze more quickly than untreated mice.   We begin with our subjects: six mice.  For convenience, the mice will be referred to by the letters A, B, C, D, E, F. Three of these mice are to be randomly selected for the experimental treatment, and the other three are put into a control group in which the subjects receive a placebo. We will next randomly choose the order in which the mice are selected to run the maze. The time spent finishing the maze for all of the mice will be noted, and a mean of each group will be computed. Suppose that our random selection has mice A, C, and E in the experimental group, with the other mice in the placebo control group. After the treatment has been implemented, we randomly choose the order for the mice to run through the maze.   The run times for each of the mice are: Mouse A runs the race in 10 secondsMouse B runs the race in 12 secondsMouse C runs the race in 9 secondsMouse D runs the race in 11 secondsMouse E runs the race in 11 secondsMouse F runs the race in 13 seconds. The average time to complete the maze for the mice in the experimental group is 10 seconds. The average time to complete the maze for those in the control group is 12 seconds. We could ask a couple of questions. Is the treatment really the reason for the faster average time? Or were we just lucky in our selection of control and experimental group?  The treatment may have had no effect and we randomly chose the slower mice to receive the placebo and faster mice to receive the treatment.  A permutation test will help to answer these questions. Hypotheses The hypotheses for our permutation test are: The null hypothesis is the statement of no effect.  For this specific test, we have H0: There is no difference between treatment groups.  The mean time to run the maze for all mice with no treatment is the same as the mean time for all mice with the treatment.The alternative hypothesis is what we are trying to establish evidence in favor of. In this case, we would have Ha: The mean time for all mice with the treatment will be faster than the mean time for all mice without the treatment. Permutations There are six mice, and there are three places in the experimental group. This means that the number of possible experimental groups are given by the number of combinations C(6,3) 6!/(3!3!) 20. The remaining individuals would be part of the control group. So there are 20 different ways to randomly choose individuals into our two groups. The assignment of A, C, and E to the experimental group was done randomly.  Since there are 20 such configurations, the specific one with A, C, and E in the experimental group has a probability of 1/20 5% of occurring. We need to determine all 20 configurations of the experimental group of the individuals in our study. Experimental group: A B C and Control group: D E FExperimental group: A B D and Control group: C E FExperimental group: A B E and Control group: C D FExperimental group: A B F and Control group: C D EExperimental group: A C D and Control group: B E FExperimental group: A C E and Control group: B D FExperimental group: A C F and Control group: B D EExperimental group: A D E and Control group: B C FExperimental group: A D F and Control group: B C EExperimental group: A E F and Control group: B C DExperimental group: B C D and Control group: A E FExperimental group: B C E and Control group: A D FExperimental group: B C F and Control group: A D EExperimental group: B D E and Control group: A C FExperimental group: B D F and Control group: A C EExperimental group: B E F and Control group: A C DExperimental group: C D E and Control group: A B FExperimental group: C D F and Control group: A B EExperimental group: C E F and Control group: A B DExperimental group: D E F and Control group: A B C We then look at each configuration of experimental and control groups. We calculate the mean for each of the 20 permutations in the listing above.  For example, for the first, A, B and C have times of 10, 12 and 9, respectively.  The mean of these three numbers is 10.3333.  Also in this first permutation, D, E and F have times of 11, 11 and 13, respectively.  This has an average of 11.6666. After calculating the mean of each group, we calculate the difference between these means. Each of the following corresponds to the difference between the experimental and control groups that were listed above. Placebo - Treatment   1.333333333 secondsPlacebo - Treatment   0 secondsPlacebo - Treatment   0 secondsPlacebo - Treatment -1.333333333 secondsPlacebo - Treatment 2 secondsPlacebo - Treatment 2 secondsPlacebo - Treatment 0.666666667 secondsPlacebo - Treatment 0.666666667 secondsPlacebo - Treatment -0.666666667 secondsPlacebo - Treatment -0.666666667 secondsPlacebo - Treatment 0.666666667 secondsPlacebo - Treatment   0.666666667 secondsPlacebo - Treatment -0.666666667 secondsPlacebo - Treatment -0.666666667 secondsPlacebo - Treatment -2 secondsPlacebo - Treatment -2 secondsPlacebo - Treatment 1.333333333 secondsPlacebo - Treatment 0 secondsPlacebo - Treatment 0 secondsPlacebo - Treatment -1.333333333 seconds P-Value Now we rank the differences between the means from each group that we noted above. We also tabulate the percentage of our 20 different configurations that are represented by each difference in means. For example, four of the 20 had no difference between the means of the control and treatment groups. This accounts for 20% of the 20 configurations noted above. -2 for 10%-1.33 for 10 %-0.667 for 20%0 for 20 %0.667 for 20%1.33 for 10%2 for 10%. Here we compare this listing to our observed result. Our random selection of mice for the treatment and control groups resulted in an average difference of 2 seconds. We also see that this difference corresponds to 10% of all possible samples.  The result is that for this study we have a p-value of 10%.

What is economic growth Discuss the factors that promote economic growth in ( Australia ) - Essay Example The factors that promote economic growth within Australia comprise of its service sector which depicts around 68% of the GDP. Also the role of the agricultural and mining sectors is of utmost essence as these signify about 57% of Australian exports (Blackie, 2008). Economic growth within Australia is bolstered by being dependent on imported crude oil as well as petroleum products. The economic growth is manifested time and again by the strength of the Australian Dollar which has made its mark not only within the nation but also in the Commonwealth comity of nations. The inflation is at 2.8% by 2010 estimates and Gini index stands at 0.331 by 2009 figures (Dixon, 2010). In 2010, $210 billion worth of exports were recorded which suggests for success within the economic growth modules. It can be easily suggested that the economic growth domains within Australia are set on the right pattern and one can look forward to seeing more similar dimensions coming to the fore with the advent of

Thesis statement - Essay Example This latter theme of using a story as a form of warning has been explored in the story of the lost continent Atlantis where its rulers were very cruel and unjust (Forsyth 54). Almost without exception, Greek myths are told in an entertaining style so audiences will pay close attention to the lesson that a mythical story contains. This lesson is usually in the form of a parable or a riddle to encourage audiences to discuss, debate, and detail all the twists and turns that a hero goes through in that myth. These Greek myths are intentionally to be shrouded in controversies so there will be no easy answers or solutions for an audience. It was the intent of the storyteller to foster further interest in the myth by using various forms of telling the myth about gods and heroes such as through epics, poems, parables, or riddles. As mentioned above, the story of the lost world of Atlantis continues to endure even up to the present time and this ensuring durability of the story, whether myth or not, achieves the main purpose of the Greeks which was to tell a story that will last for generations to come and yet at the same time, impart a valuable lesson for the population, including the politicians. As it happens, Atlantis was claimed to have been lost due to the cruelty of its rulers and Plato (427-347 B.C.) warned the rulers of Greek city-states like Athens to rule with justice always. Roman mythology is basically just a duplicate copy of Greek mythology but with a big difference. This is because Roman mythology does not contain the distinguishing feature of Greek mythology which was to impart a life-long lesson to audiences; rather, this Roman version of the Greek mythology contains a lot of embellishments designed to conform to the more war-like nature of the ancient Roman culture. While Greek mythology is preponderant on divine themes and on questions about the universe, the

Study case - Essay Example The defendant had flouted the civil rights of the employees enshrined in the Civil Rights Act of 1991. The defendant had flouted Civil Rights Act of 1991 which prohibits employers from discriminating their employees. The company resolved this by setting up a prayer special room at the plant (Robert & John 103). Tyson Foods also had a conflict that arose when they attempted to replace Labor Day with Eid al-Fitr. The non Muslim employees complained about this move. The company addressed the issue by allowing all their employees (Muslim and Non-Muslim) eight paid holidays (Robert & John 103). The holidays included; Memorial day, Martin Luther King Day, New Years Day, Christmas Day, Thanksgiving Day and a personal holiday. Subject to the approval of their supervisors, the employees had the option of spending their personal holidays either for their birthday or Eid  al-Fitr. The company thus incurred more operational expenses by increasing the number of paid holidays to eight. Comparing the solutions adopted by the two companies, unlike Tyson foods, JBS-SWIFT’s solution will yield the company the greatest positive yield because, it will not incur additional operational cost (Robert & John

Public Relation Core Values Essay Example for Free

Public Relation Core Values Essay Public Relations Society of America (PRSA) has extremely important core ethical values that include advocacy, honesty, expertise, independence, loyalty, and fairness. All of which will help further a public relations practitioner in their career. Every practitioner handles every job differently, in a way thats going to benefit both the company they are working for as well as the public. Honesty should be the most important core value for every practitioner. Not only should it be the most important core value in the work field, it should also be the most important core value in everyones life as well. On the other hand, practitioners tend to ignore their core values while working. One of the biggest values they tend to ignore or overlook is fairness. Mark Twain once said, Honesty is the best policy; when there is money in it. This quote should be every public relations practitioner motto because being honest will always lead you to conducting better business with clients. Clients want honest individuals working for them because the company expects the practitioner to represent the company in a way thats going to gain the publics trust. When the public has your trust, they are going to shop at your company rather than one who puts out false advertisement and has a poor look in the publics eyes. Not only does the quotes speak for itself, but honesty is simply the best way to conduct business. Some practitioners try their hardest to provide equally fair service to every client. Fairness is a core value that all practitioners respect but is hard to do at times. When dealing with clients, employers, peers,vendors, competitors, and most important the public, its hard to keep everyone happy. Lets say a practitioner is dealing directly with a company for the release of a new product. The company producing the item may not want competitors knowing about it so they can keep the technological edge on its competitors but also at the same time they want the public to hear about whats new. Since they manage what information the public hears, its essential what they say. No matter what they say or dont say, someones always going to want more. With that being said, someones not going to be happy. Life in general isnt always fair, so when faced with a situation that can cause grey areas with others, do what you ethically think is the right thing.

Education Systems Comparison: Australia and Mongolia

Education Systems Comparison: Australia and Mongolia COMPARISON BETWEEN MONGOLIAN AND AUSTRALIAN EDUCATION SYSTEM I would like to introduce comparison between Mongolian and Australian Education system in several areas such as general statement, access, quality and efficiency. First of all I would like to introduce general statement for both countries. Education in both countries follows preschool, primary and secondary education and technical education and vocational training and tertiary education. Both countries preschool education is non compulsory. Mongolian preschool education is offered to children agedÂÂ  2 to 5 in kindergarten, but Australian preschool education offered children aged 3 to 5. Mongolian preschool education is an instructional institution and by the Mongolian Preschool education law kindergartens shall provide preschool education to children of preschool age and ensure their school preparedness. Australian early childhood education has many types of preschool education such as kindergarten, child care center, Montessori center and act. Also, there are many similarities on primary and secondary education in two countries which means 12 year schooling system. The official enrolment age is 6 year old children in two countries. In addition, the Mongolian Government initiated transforming primary and secondary schools into a 12 year system in 2008. This transition will be complete by 2016. In Mongolia, that 6 years of primary, 3 years of lower secondary and 3 years of upper secondary schooling. In Australia that 7 years of primary and 5 years of secondary. In Australia, in the some states territories, primary schools often include a pre-school. In Mongolia, technical education and vocational training (1-2.5 years) sub-sector comprises specialized upper secondary schools as well as post-secondary diploma programs housed in higher education institutions. Therefore, in Australia, each state has a Vocational Education and Training or Technical and Further Education system. It is prepares people for work in a career that does not need a university degree. In Mongolia, higher education is awarded by colleges, institutes and universities. At the higher education level, bachelor programs usually last four to five years and six years for medical programs. Masters programs usually require one to two years and doctorate programs require three to four years to complete. Likewise, Australian higher education (6+) awards are classified as follows certificate, diploma and associate degrees, which take one to two years to complete, some aspects of higher education are the responsibility of States and Territories. In particular, most universities are recognized under the State and Territory legislation. Secondly, I would like to compare access of education in both countries. In Mongolia, 76.3 percent preschool age children attended in preschool education services. In 2009/2010 academic year, there are 785,8 thousand students enrolled in institutions of formal education. There were 102, 6 thousand children in 814 kindergartens. In 2009, 58.6 percent of pre-school children who are 2-5 year olds enrolled at institutionalized education programs and 17.4 percent of total pre-school children enrolled in alternative forms of educational services. In Australia 97.5 per cent of children attended for early childhood education the year before school. The year before a child is due to attend primary school is the main year for pre-school education. This year is far more commonly attended, and may take the form of a few hours of activity during weekdays. Preschool is in some states and territories relatively unregulated. In Mongolia, in 2009/2010 academic year, 557,3 thousand pupils in 710 primary and secondary schools. The primary and secondary education net enrollment rate was 91.5 percent. An addition, girls enrollment in primary and secondary cycle is greater than boys. In Australia, primary and secondary education is compulsory between the ages of 6 to 17, depending on the state or territory. The primary and secondary education net enrollment rate was 99.3 percent. In recent years, over three quarters of students stay at school until they are seventeen. Government schools educate about two thirds of Australian students, with the other third in Catholic and Independent schools. A small portion of students are legally home-schooled. Higher Education in Mongolia has universities and colleges. There are 146 universities, which is 42 are public, 99 are private and 5 are international. During the last 5 years number of students enrolled in higher education institutions increased by 70,1 per cent. The proportion of female students is 61.8% of total higher education enrolment. That data indicate an unusual reverse gender gap in higher education. This is particularly noticeable at the higher levels of education where typically female greatly outnumber male students. Last 5 years enrolments in occupational programs such as foreign languages, law, computer science, engineering, medicine, and tourism was more than double. Tertiary education in Australia provider is university self-accrediting provider, non self-accrediting provider. In 2009, the Australian higher education system consisted of 41 universities, of which 37 are public institutions, 2 are private, and 2 are Australian branches of overseas universities; 2 other self-accrediting higher education institutions; and non-self-accrediting higher education providers accredited by State and Territory authorities, numbering more than 150 as listed on State and Territory registers. These include several that are registered in more than one state and territory. Thirdly, in short, I want to compare and contrast quality of education both countries. The most important aspect for quality education is the learning achievement. According to the Program for International Student Assessment for 2006 ranks the Australian education system as 6th on a worldwide scale for Reading, 8th for Science and 13th for Mathematics. The Education Index, published with the UNs Human Development Index in 2008, based on data from 2006, lists Australia as 0.993, amongst the highest in the world, however Mongolia lists as 71, the medium level. In addition, many universities in Australia have gained international recognition. Two of the most acknowledged are the Academic Ranking of World Universities, produced by Shanghai Jiao Tong University, and the THES QS World University Rankings, which in 2006, had no fewer than 13 universities amongst the worlds top 200. That is why many foreign students wants to study in Australia at schools and universities. Quality in education is not good in Mongolia. Particularly, urban-rural gap in education quality still exist. According to some recent research, children attending rural schools perform significantly worse than children attending schools in aimag centers and Ulaanbaatar. Rural schools have limited access to resources needed to support higher learning achievements. Another main issue of qualitative aspects in education is teacher and children ratio. In Mongolia teacher and children ratio in the preschool is 25:2 and 30:1 is for secondary school.2 But 18:3 is for preschool and secondary is about 20:1 in Australia.5 It depends states and territories. Teachers are key players in implementing of the education sector, especially in classroom and teaching and learning quality, which is highly dependable on their professional capacity and supply. Two countries teacher qualification and professional knowledge and skills are similar, but teaching method is different. As I mentioned the last another issue of qualitative aspects in education is curriculum. The Mongolian Government approved a new set of competence based education curriculum/standards for pre school, primary and secondary education emphasizing the quality of education. These new curriculum is being introduced in the school year of 2005/2006. On the other hand, national curriculum /standard has renewed to be promoting a human development as develop pupils competence in terms of communication skills, self-confident, a critical thinking and problem solving abilities etc. In Australia there is a mandatory curriculum in addition to elective subjects. For the students are required to take state-wide external tests in English-literacy, mathematics, science, Australian history, geography, civics and citizenship and computing skills in. Finally, I want to write a few words about educational efficiency. The Mongolian Law on Education stipulates that at least 20 percent of the government budget is allocated to education. Government expenditure on education as a percent of GDP is 9 and a percent of GNP is 19.09 in 2004. Education expenditure has significantly increased over the last few years. Educations share of public expenditure has also remained consistently high, averaging 18.6 percent over the 2008-2010 period, although it has not quite reached more than 20 percent share as required by the Education Law, (revised in 2006). But the national education budget has increased by 2.5 times in 2004 as compared to 1996. The education sector is financed principally from two sources: the Central budget (81.7 percent in 2008) and the local budget (9.3 percent) with revenue raised at province and city levels. Other sources of revenue include tuition fees (4.1 percent), donations from individuals and organisations (1.6percent), project funds (0.1 percent) and others (2.7percent). In Mongolia, school and kindergarten financing is operated based on per child normative variable expenses with adjusting indexes. Indexes used to adjust the different situations in terms of population density, distance as remoteness of school location so on. However, some of remote and rural schools are still facing problems related with financial shortages due to not enough children attending in their kindergarten and school. Since 1997, state financing only fixed costs such as heating, electricity and water in higher education institutions. Student tuition fees constitute the major income source for universities, institutes and colleges. It makes up 80% of higher education income. In conclusion, it can be clearly seen that Australian and Mongolian education system are a few similarities some area such as general statements and accesses. However, the quality in education two countries is very different. Quality in education in Australia is the highest in the world, although in Mongolia, such as many indicators of the education quality and efficiency are not good enough and we have to change trends also, remind that there is need for policy and operational strategy reforms. Therefore, Mongolian education sector is undergoing new stage development reform. It has encountered new challenges created by poverty and social deprivation. The following issues are considerable in future development of education sector in Mongolia. Generally, Australian education system has a good policy, management, and sustainable development for every part of the education sub sectors. Finally, I believe that to improve relationship and to expand cooperation between Australian and Mongo lian education sector.

Graduation Speech -- Graduation Speech, Commencement Address

The first day of kindergarten, we clung to our parents afraid of the new experiences that awaited us. We looked around at all of the other faces not sure what to think. Fear and doubt crippled us. Little did we know that this day was the beginning of a journey stock full of obstacles and rewards. Kindergarten was a breeze. We learned the ABCs, made friends, and finally counted to one hundred. Then we went into elementary. We saw new students join our classes throughout these long but short elementary years. Teachers could see boys and girls running away from each other screaming, "Ew, you got cooties!" Life was a breeze all the way through to middle school. We came into middle school with no idea what to be prepared for. None the less, we made it. We were the youngest. Fifth grade ...

Goal Setting Theory Essay

The idea that human behavior is motivated and regulated by goals and aspirations has long been recognized by psychologists. Goal-Setting Theory can be traced back to Edwin Locke and Gary Latham; they elaborated on the basic notion of goal setting and have described how this drives behavior in organization. Goal-setting theory helps to explain individual differences in motivation and performance. Goals are defined as the desired outcomes in terms of level of performance to be attained on a task rather that the desire to take specific section (Muchinsky, 2005). It is thus a person’s intention to attain developed goals that can serve as a principal determinant of motivation. For instance, as a student I have a goal of attaining an A grade on this subject which would motivate me to study well and participate more in class in order to achieve my goal. According to Locke, goals have motivational value for three reasons which are: goals serve to direct and focus our attention particular direction; goals help us to maintain task persistence; and the existence of goals tends to facilitate the development task strategies. Attributes of goals that make them motivating are the difficulty, acceptance, specificity and feedback to motivate performance. It has been viewed that goals that are difficult are more motivating than easier goals. For instance, a salesperson is going to be more motivated if he has a goal of making $10,000 in commission, rather than a goal of $5,000. The second attribute is the goal acceptance, wherein a person would believe that he can attain a particular goal set to him or by him. Goals are much more motivating when they are specified in a particular level of performance, example, an individual must be able to sell 10 units of apartments in the next month rather than ‘be a good salesperson’ which is very vague motivation. Attaining a goal is often a hard process; thus it is important that employees receive feedback regarding their progress and once a goal is accomplished a pleasurable emotional state called job satisfaction will be experience. Principles of goal-setting theory has been a very influential approach and one of the most valid and practiced theories of employee motivation in organizational psychology.
