Is Embryonic Stem Cell Research Ethical - 951 Words

Is Embryonic Stem Cell Research Ethical? The introduction and expansion of embryonic stem cell research initiated a highly debated ethical topic. Can our society agree to disagree? What are embryonic stem cells? What are stem cells? Is all stem cell research considered abortion? Debates surrounding embryonic stem cell research is further complicated by social standards and needs, religious beliefs, and personal morals. In November of 1998, a group of researchers announced that they had successfully isolated and grown a special kind of cell with the potential to develop into virtually any kind of human tissue. The scientists had made the discovery of embryonic stem cells. The discovery was considered to be an innovative†¦show more content†¦Any time someone had to get a lung transplanted there would be no need to find a donor; and once the lung was transplanted, the patient would not have to receive drugs afterwards, because his immune system would automatically accept the lung. Also, organs that canno t possibly be donated and accepted in a new body, like spinal tissue, could be duplicated. This means if an individual was paralyzed, hers or his spinal tissue could be duplicated by stem cells and then transplanted. In addition, it may become possible, with embryonic stem cells, to generate healthy heart muscle cells in the laboratory and then transplant those cells into patients with chronic heart disease. Through the use of embryonic stem cells, brain cells and many other cells can be cultured and then transplanted into a patient to cure Alzheimers disease and other brain and heart related diseases. A person diagnosed with diabetes, a disease in which a person is unable to produce insulin, can have cells cultured to form insulin producing cells and have them transplanted. Because of the limited number of cells adult stem cells are able to produce; these diseases would be unable to be cured through their use. Stem cells could also be used to test new drugs. With this achi evement scientists could be able to cure cancer and many other diseases. This would reduce the view of cancer as a fatal disease, to something that can be overcome, such as a common cold.

The Taming of the Shrew A Feminist Reading

A feminist reading of Shakespeares The Taming of the Shew throws up some interesting questions for a modern audience. We can appreciate that this play was written over 400 years ago and, as a result, we can understand that values and attitudes towards women and their role in society were very different then than now.   Subordination This play is a celebration of a woman being subordinated. Not only does Katherine become the passive and obedient partner of Petruchio (due to his starving her of food and sleep) but she also adopts this view of women for herself and ​evangelizes this mode of being to other women. Her final speech dictates that women must obey their husbands and be grateful. She suggests that if women do contest their husbands, they come across as ‘bereft of beauty.’ They must look pretty and be quiet. She even suggests that the female anatomy is unsuitable for hard work, being soft and weak she is unsuited to toil and that a woman’s demeanour should be reflected by her soft and smooth exterior. Modern Contrasts This flies in the face of what we learn about women in today’s ‘equal’ society. However, when you consider one of the most successful books of recent times; Fifty Shades of Grey, about a young woman Anastasia learning to be subordinate to her sexually dominant partner Christian, a book particularly popular with women; one has to wonder whether there is something appealing to women about a man taking charge and ‘taming’ the female in the relationship? Increasingly, women are taking more high powered positions in the workplace and in society in general. Is the idea of a man taking on all the responsibility and burden of work more appealing as a result?   Would all women really prefer to be ’kept women’, with the small dispensation of having to obey your men folk in return? Are we willing to pay the price of male brutality over women for a quiet life as Katherine is? Hopefully the answer is no. Katherine - A Feminist Icon? Katherine is a character who initially speaks her mind she is strong and witty and is more intelligent than many of her male counterparts. This can be admired by a female readership.   Conversely, what woman would want to emulate Bianca’s character who is essentially just beautiful but unremarkable in other aspects of her character? Unfortunately it appears that Katherine wants to emulate her sister and eventually becomes even less willing than Bianca to challenge the men in her life as a result. Was the need for companionship more important to Katherine than her independence and individuality? One could argue that Women are still celebrated more for their beauty than for any other achievement in today’s society. Many women internalize misogyny and behave accordingly without even knowing it. Women like Rhianna cavort and look sexually available on MTV to buy into a male fantasy in order to sell their music. They shave all over in order to conform to the current male fantasy demonstrated in prolific pornography. Women are not equal in today’s society and one could argue that they are even less so than in Shakespeare’s day...at least Katherine was just made to be subordinate and sexually available to one man, not millions. How Do You Solve a Problem Like Katherine Feisty, outspoken, opinionated Katherine was a problem to be solved in this play. Perhaps Shakespeare was demonstrating the way in which women are beaten down, criticised and derided for being themselves and in an ironic way was challenging this? Petruchio is not a likable character; he agrees to marry Katherine for the money and treats her badly throughout, an audience’s sympathy is not with him. An audience may admire Petruchio’s arrogance and tenacity but we are also very aware of his brutality. Perhaps this makes him slightly attractive in that he is so manful, perhaps this is even more attractive to a modern audience who is tired of the metrosexual male and would like a resurgence of the cave man? Whatever the answer to these questions, we have somewhat established that women are only slightly more emancipated now than in Shakespeare’s Britain (even this contention is debateable). The Taming of The Shrew raises issues about female desire:   Do women really want a man to tell them what to do and take charge or is an equal partnership something they should be striving for?If a woman wants a man to be in charge does that make her an enemy of the feminist?If a woman enjoys the Taming of the Shrew or Fifty Shades of Grey (Sorry to compare the two, Fifty Shades of Grey is by no means on a par in literary terms!) is she internalising patriarchal control or responding to an innate desire to be controlled? Perhaps when women are fully emancipated these narratives will be rejected completely by women? Either way we can learn from The Taming of the Shrew about our own culture, predilections and prejudices.

Trying Juveniles as Adults - 1404 Words

When it comes to trying juveniles as adults, it is a strong issue to follow through, but it has been a controversial topic to the public. This topic is a controversial topic even considering that there are numerous arguments to put forth on both sides.

Therefore, Cameron showed the signs he was showing because he most likely didn’t fully understand what was going on, or what he did. During this time, when juveniles have no responsibilities, and maturity it is not expected of them, they most likely do not understand the consequences.

Management accounting and decision making free essay sample

According to Burger (2008) â€Å"Accounting is the language of business. A lot of people think its just numbers, but its really a lot more than that. There are a lot of areas outside of numbers that need to be looked at, processes and procedures, what the tone of the company is. Accounting will take you in just about any direction in a company. ~ Wade Becker, CPA, Beard, Miller Co. The job description of many professions is changing nowadays. The skills to perform a certain job require more skills to perform a particular job. If an example of Information Technology is to be taken then it is realized that once they were left to do IT related jobs or make computers work however, in today’s world IT professionals are now moving into higher level management positions which require them to perform many other tasks which may not be directly related to the their profession. Therefore, a stereotypical role of an accountant was once considered a â€Å"number person† but today’s era demands accounting professional to own and use interactive and communication skills to help with the decision making process across all areas of a business. In a managerial accounting world all professionals must communicate their ideas to other companies using ways which are tactful and effective. Siegel (2000) states that â€Å"Management accountants should be great communicators.† Durry C (1992) believes that management accounting is â€Å"concerned with providing information to managers –that is people inside an organization who direct and control the operations.† In the 19th Century financial accounting was considered to be the need of a society which later evolved to Management accounting. Management accounting became a prerequisite for more detailed information for stock control, product costing and decisions affecting the future. Accounting is facing numerous challenges, as Elkington (1998) states â€Å"business people must increasingly recognise that the challenge now is to help to deliver simultaneously economic prosperity, environmental quality and social equity.† All this is making business managers to re-examine the practices that are currently led. Cokins G and Hicks D believe that Managerial accounting is part of an organisations management information system. To follow any business or an organisation aim managers engage in activities which involve an effective cost model as it can be a great asset to an organisation. A business or projects to be a success or failure three things need to be considered, for  example, cost, schedule and performance. A project should be continued within the means provided otherwise stakeholders struggle to finance the project and its abandoned. A success of a manager is when appropriate tools are employed and sound safe decisions are made and follow on with apply ing substantial level of expertise to have effective cost management. The world today is surrounded by increasingly advanced technology such as computer assisted manufacturing and flexible manufacturing systems. According to Cokins and Hicks organizations to compete effectively need to understand the cost of each product or element of their value chain from product design and purchase of material therefore internal cost is very important as mentioned in Cokins and Hicks article because it becomes critical for competitive action and increasing shareholders wealth in the current globally competitive economy. Management accounting systems are the benefactors of the precarious internal cost information. There has been few criticisms leading to the literature of Management accounting system and it has been labeled outdated and there has been criticisms linked to its consistency as it has been thought that it does not provide consistent information with the current strategic management paradigm. Cokins and Hicks believe that systems designs elements should capture the fundamental technology, promote a business based on effective cost model, quality and lead time. Precise and appropriate cost information is critical to management’s decision making procedures (Cokins and Hicks) and the literature being studied reveals Management accounting system reflects the organizational complications of the current world however traditional Management accounting systems do not replicate current organizational era as all costing procedures were designed around late nineteenth century. In traditional era product line diversity was not very common and cost of materials and direct labour were the main components of production cost but the environment today is surrounded around advanced technology and automation and that has led the prime cost to be the overhead component. The overhead costs are altering product cost because of the old management accounting system techniques. Management accounting needs a unique set of skills and behaviour. According to Cokins and Hicks Accounting Management framework gives business a planned approach to address all factors that will manage accounts interface and todays reality. Cooper and Kaplan believe there are six critical factors which play a crucial role  in Accounting Management framework which also backs Cokins and Hicks journal being studied for this assignment. The first one is organizational structure. It includes factors such as whom and how you manage accounts, why and how you organize around them. The second account management success factor is people as they need the appropriate skills, knowledge and skills to experience and perform the role. The third factor is tools and technology as it must support the account management processes and must balance â€Å"help† as â€Å"control.† The fourth one is compensations structures as they can inhibit change or accelerate adoption. The fifth account management success factors are processes and methodologies as they should align with the customer, drive growth and opportunity plan and the last factor channels and alliances must be managed effectively through the account manager interface.it is up to an organization to structure their useful employees around their key customers and that can create a deep impact on their performance. First few deliberate decisions need to be taken in terms of placement of accounts management resources such as market and territory. Cokins and Hicks believe management team need to plan using methodology a number of factors to create a ranking based on the business goal for the affiliation and ability to deliver. Once these methodologies are selected they can play a vital role in team structure and it will help to deal with issues such as ownership or shareholders Cokins and Hicks discuss the difference between cost accounting and managerial accounting and the strength of their article is that managerial accounting is tied with GAAP whereas cost accounting is used within a business to manage that particular business. Accounting standards of a country provide guidelines to an accountant so they can be used while reporting economic transactions of a business. United Kingdom accounting has improved a lot as mentioned in the journal being studied for this particular assignment. Managers have immense pressure to improve financial management practices to improve service to the community and it is not only done on national level. Managerial accountants have to keep accountant standards fair globally and that is mainly done through Accounting Standards Committee. â€Å"What gets measured gets managed, What needs managed gets measured† (Peter Drucker) famous quotes has cause many criticisms but if the practices and development mentioned in Cokins and Hicks journal are to be analyzed, one can conclude this quote has some truth. Managers of a business  often use this quote indicates that active management of businesses should be given importance instead of accountability to gain desired goals. It will lead to survive in today’s world of information age competition therefore businesses should ensure they are using management systems resulting from their strengths. Any business main task is to develop an active measurement system as it is main part of the management process. Good management practices lead to using certain measures to plan, implement and improve certain aspects of an organization. According to Kaplan, (1994) measurement is a difficult task because it is not related to science so there are no facts and does not have rules between variables. Furthermore, systems which are used by management accountants will make sure that actions are taken according to the strategies and objectives developed. There has been an immense amount of research on management accountants and the research evidence has proved that businesses which are using a developed measurement system are developing and gaining profits therefore, Gates (1991) states â€Å"an organizations objectives and severity of measures, varies, depending on people, culture and past experiences of the organization.† The management accountant was developed after 1980s and it was seen a golden era in management accounting research as it saw new techniques and practices beneficial to the management accounting. One of the techniques developed in 80s was strategic management accounting and some of the processes which fall under the category of strategic management accounting are activity based costing and balance scorecard. The balance scorecard emerged after it was realized that there is a need of an integrated system which can be used to measure both financial and non-financial performances. It helps companies to view their performances on a regular basis and it gave a clear view of what should be measured in order to balance a particular business financial perspectives. The balance score card consists of four functions known as learning and growth perspective. It means how to achieve a certain organizations goals and how will a business will sustain its ability to change and improve. the second perspective is financial and its aim is to succeed financially and is mainly concerned with making a good impression to shareholders. Another perspective is based on customers as they can determine sales and to achieve business goals a good impression is to be made upon customers. The last perspective is known as internal business  processes. It mainly deals with how to satisfy customers and shareholders and what business processes must a certain business excel as. (Kaplan and Norton:1996) Balance scorecard is one of the necessities for any organization and it is used by the management to accomplish vision and strategies of an organization and it has few other benefits too such as, making sure managers are managing every single variable within an organization and are not working upon favoritism. If more developments are to be discussed and strength of Cokins and Hicks journal than one must not forget one of the major development in an accounting field known as Activity-based costing. Kaplan and Cooper gave this idea a new beginning as it was not very well known in previous years. According to Kaplan (1996) manufacturing costs are determined by amount of â€Å"activities† and the key to effective cost control is maintaining the effectiveness of the activities ABC recognizes better cost pools for indirect costs and then implies cost drivers to relate the expenses in the cost pools to activities of an organization. ABC has become more popular in recent years but faces a lot of criticisms too due to the fact that sometimes businesses face difficulties in implementing this technique. ABC is enhanced further by Activity-based management as they believe in planning and measurement and class them as key factors in a competitive business environment. To conclude, If an organization has accounts managers or not a success can only be achieved if a successful profile is valued. It can be done through an industry as it will help determine to what extent an account manager is an industry expert and the second is through customers as it is vital for an accountant to understand the businesses being worked upon. The profession Accountancy has seen many developments and criticisms however, since 1980s there has been many changes in management accountancy. The new changes are focusing on measurement tools within a business to manage its aims and objectives. Management techniques are discussed briefly in this essay and they emphasize on Cokins and Hicks journal that management decisions can be made better by using effective management measurement tools and it leads to improving the management of an organization. There can be problem with new measurement techniques as nothing in life comes with a guarantee however, new ideas can be used on t he basis of guess work and the new contributions could be a way forward.
