The Field Of Information Retrieval And Web Analysis

ABSTRACT Opinions play a crucial role in the decision making process. Analysis in the field of making decisions and setting policies has shown that sentiment analysis and Opinion mining has become increasingly important in the field of Information Retrieval and Web analysis. In the past years, the growth of user generated data in web forums, social networking sites and other social platforms is tremendous, which diverts our study towards mining the opinions on web. In this paper, we have presented a novel methodology to classify the tweets and the complete opinion mining system is explained on the basis of survey and analysis. A flowchart has been proposed in which the overall picture of classification of twitter data has been proposed and accuracy of the evaluation strategies by various supervised learning algorithms has been evaluated. Review data is collected for various product domains from micro blogging sites like twitter, face book. Keywords Opinions, Web mining, Sentiment Analysis, Supervised Learning, Mining. 1. INTRODUCTION In recent years, we have witnessed that a huge amount of opinionated text is available which have greatly influenced our social and political systems.

Should Physician-Assisted Suicide be Legal Free Essays

Most people in North America die what may be called a bad death. One study found that ‘More often than not, patients died in pain, their desires concerning treatment neglected, after spending 10 days or more in an intensive care unit’† (Horgan). The word euthanasia is the opposite of bad death in that its Greek origins of eu (good) and thanatos (death) have it meaning good death. We will write a custom essay sample on Should Physician-Assisted Suicide be Legal? or any similar topic only for you Order Now    The media attention dedicated to Dr.   Jack Kevorkian, the â€Å"death doctor,† in the 1980s has given rise to some interesting questions and moral dilemmas concerning the right to die.   Ã‚  Jack Kevorkian made use of suicide machines, rigged contraptions that would deliver a death blow, to his patients that recommended them. Basically, euthanasia is the mercy killing of an individual who has a terminal illness and who might be in considerable pain or have no quality of life.   It can take two forms.   Passive Euthanasia is simply denying the patient lifesaving treatments.   Examples of this can be the removal of feeding tubes or breathing tubes.   Active Euthanasia is, as the name implies, an active way to put a suffering individual to death.   It may include administering lethal doses of painkillers or toxins to the individual.   One definition of physician assisted suicide which combines both type of euthanasia and therefore has been dubbed ‘voluntary passive euthanasia (VPE) is â€Å"A physician supplies information and/or the means of committing suicide (e.g. a prescription for lethal dose of sleeping pills, or a supply of carbon monoxide gas) to a person, so that they can easily terminate their own life (Robinson). Recently morals and ethics have come into conflict over this issue .   Is the right to die inherent in each individual?   What role does dignity play?   Is the quality of life more important than the sanctity of life? The majority of people look to answer these questions from their own personal experiences.   Those who have watched love ones die long and painful deaths will usually wish to avoid those ends themselves.   When death is imminent, suffering for a few extra days spent in pain or even unconscious or unaware of one’s surroundings seems a futile and even cruel punishment to inflict upon oneself or a loved one.   Others fear that the depression and pain experienced by the dying person are clouding their decision-making abilities. However, personal feelings are the least likely to be validated because everyone’s personal feelings and view differ.   Therefore, other levels of the moral and legal hierarchy must be considered. Many attempt to resolve this dilemma through religious avenues.   Religion as a basis for legal decisions is not uncommon.   Legally, the church and state must remain separate, but many exceptions have been made.   A moment of silence in school can be used for prayer.   Member of certain religious denominations may refuse medical treatment such as vaccinations for their children.   Certain individuals are not required to swear on the Bible in court, and some religious groups are even allowed controlled and illegal substances for use in religious services.   Clearly precedence has been set for breaching or at least blurring, the line between legal and moral. Most devoutly religious individuals believe that taking the life of another is immoral under any circumstances.   They believe that only God can give and take life. Clearly they view physician-assisted suicide as murder.   Doctors who do so are playing God, which is considered a sin. From a medical standpoint, doctors are often in the middle of this debate. As physicians, they are extremely knowledgeable about the pain and suffering associated with terminal diseases and injuries.   They may feel personally saddened at this deterioration of a patient that they have come to know.   However, the doctors are bound by the Hippocratic Oath in which they have sworn â€Å"first, do no harm.†Ã‚   At this point, they possible feel conflicted between their professional duty and their personal feelings. Legally, taking one’s own life is suicide and taking another’s life is murder. Wikipedia defines murder as â€Å"the premeditated unlawful killing of one human being by another through any action intended to kill or cause grievous bodily harm† (Murder). This definition, doctors who take the life of a patient, even one who is suffering horrible and certain to die, is guilty of murder. Thus, the question of should physician-assisted suicide be legal is certainly complex.   Public opinion polls show that the international public is generally supportive of euthanasia.   According to a Gallup poll in 1997, 57% of people are in favor and 35% are opposed in the US.   In Canada, 76% are supportive with that number rising to 80% in Britain, 81% in Australia and 92% in the Netherlands (Reed, A12). The right to die is just one of the many choices that have come under the legislative domain.   Roe v. Wade gave the choice of abortion to women.   However, this right is now in jeopardy.   It seem that the US government is afraid to give choices about personal life decisions to the American public out of fear of religious backlash.   This has led to doctors fearing to provide this humanitarian aid out of fear of legal backlash in the form of lawsuits or even prosecution. Sue Rodriguez was the center of a high profile terminally ill case in Canada.   Suffering from ALS, she publicly challenged all opponents of the right to die with â€Å"Whose life is it, anyway.   Her doctor helped her commit suicide in the presence of a Canadian Member of Parliament. Neither was prosecuted (Robinson).   It is very hard to argue with the pleas of a dying woman in this situation.   However, the recent case of Terry Schiavo, in which the family had to make an interpretation of an incapacitated woman’s desires, is less cut and dried.   Human greed and hatred can interfere with just decision making and this case clearly divided America. One way to ensure that an individual’s own personal wishes are carried out is through a living will.   In 1990, the U.S. Supreme Court ruled that every individual has the constitutional right to control his or her own medical treatment and that doctors, nurses or any professional staff must follow ‘clear and convincing evidence’ of the ill individual’s wishes.   The personal position of the doctors and the family cannot override a living will (Robinson). Unfortunately, 67% of people do not have a living will (Robinson).   In absence of such a document, society is forced to the original question:   Should physician assisted suicide be legal?   Yes, it should.   First of all, the majority of the public believes that it is the right and just thing to do.   Next, legal precedents of the importance of choice in similar situations such as abortion have already been established in court.   Third, even if patients are depressed or in pain, they are still dying. The United States Justice system validates the choices of depressed individuals every day.   If a depressed person makes a choice to commit a crime, that choice is validated by an arrest, conviction and possible prison term. Prolonging their life under these circumstances is cruel and unusual punishment.   Doctors can choose as well.   Millions of people rely on doctor’s choices every day. The United States should not strip individual choice from its citizens. Citizens should be able to make the choice and then live (or, in this case, not live) by the consequences.   Physician assisted suicide should be legalized in the United States.   This way it can be documented and cases like Sue Rodriquez and Terry Schiavo will not have to dominate the media but can rest in the peace that they deserve.

Protecting or Ensuring the Health and Safety of Employees

Table of Contents Exhibit commitment Develop training program Inspect the workplace Conclusion Works Cited Protecting or ensuring the health and safety of employees who are directly affected by the activities within the organization is an important part of risk management. The employees are the most important resource and the last one that determine the performance of the organization after other factors have been satisfied (Werner DeSimone 10).Advertising We will write a custom case study sample on Protecting or Ensuring the Health and Safety of Employees specifically for you for only $16.05 $11/page Learn More Therefore, strategies that should be implemented to protect their health and safety should not only cover the context, but must be effective. Whoever conceives the initiative is not more important than the one it affects. I suppose that the debate about health and safety should be on how the intended strategy is appreciated among the subject s rather than on its perceived outcomes. Thereason is that, the effectiveness solely depends on the willingness of the subjects to contribute to the initiative. The strategies should therefore be those that initiate motivations and establish positive relationship between the deliverer and the subject. The realization here is that the human resource management is as important as the employees in protecting the health and safety of the employees, and the best recommendations are those that affect bothcontexts. Exhibit commitment Hawkins (2) suggests that the provision of health and safety of the workers is the responsibility ofparties bound by organizational policies, goals and mission. The sources of unsafe environment should not be seen as to originate from the system that caused it or the failed responsibility of an employee, but right from external factors that could have been considered in preventing it. For instance, a new faulty machine that causes an accident could be the faul t of the operator or the manager as well as the failure of the legislative bodies to commit them in seeing that the developers of such machines adhere to quality specifications. Commitment for all including the society which can protest if a facility is observed to risk the health of the people is a strong recommendation in ensuring health and safety for all. When narrowed down, corporate commitment is most important in providing health and safety of the workers. It can never be argued that the accomplishment can occur without involving the stakeholders. Health and security is a matter that requires knowledge and skill support, moral support, and financial support. At this juncture, the role of human resource department is to link the employees with the higher hierarchies of governance. While the employees are in the best position to protect them, the means to do that usually comes from above. The commitment of the management and the board will make them to value the employees and e ventually be willing to enhance their working environment.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More The effects of corporate commitment on health and safety of employees is seen in the case of North Staffordshire Combines Healthcare NHS Trust (HSE, 3). After facing improvement targets, the board set out a whole system approach to manage risks giving one of the directors responsibilityfor overseeing the health and safety in the organization. This led to a better and much improved health and safety system that enables in identifying and managing corporate risks, a transparent culture, and improvements in reporting and monitoring. In such an environment there remains only the contribution of the employees to ensure their health and safety. Employee commitment is also important as it gives the last take in the process of ensuring health and safety of the workplace (Karmis 181). No m atter how the management is committed, the employees must be ready to appreciate what is afforded. Their commitment means even their efforts to assist the management understand the ground issues in terms of health and security. This is a basis of the argument that the employees have the sole responsibility to protect themselves. As noted earlier however, the means and motivation must come from somewhere else. Workers humble themselves in order to deliver their duties so as to make a living and might never be aware of the risks associated with their working environment. Develop training program We all do what we know and improve our performance through learning new things as well as revisiting the old ones. Similarly, the employees will do what they know about health and safety and improve in that context through leaning new things. Furthermore, working environment and the equipments associated keep on changing and thus require new knowledge in order to adapt well. Therefore training is important in protecting the health and safety of the employees. The more the employees learn new ways to protect themselves, the better they shape their work places. It is not morally upright for the management to assume that the employees are safe at their workplaces when there is no effort to show them what should be done. The major role of HR is ensuring that the employees are comfortable enough to perform to the expectations of the organization. In terms of health and safety, this comfort means to arm the employees with the necessary skills and knowledge through systematic training.Advertising We will write a custom case study sample on Protecting or Ensuring the Health and Safety of Employees specifically for you for only $16.05 $11/page Learn More It is true that the managers might not understand the situation at the ground level or might not be feeling the actual weight of the matter, but they have the central role to connect the employees wi th the necessary resources. The business context is quite different as the mentoring process originates from the HR department. Most employees will innocently seek for an advice from the HR fraternity and thus imposing a moral obligation on HR to support their independence in terms of health and security through training. Most of the management members within an organization know about the basic health and security implications, and indeed have the resources to learn about them. Hence, it beats logic to argue that the members should delegateall the health and security responsibilities to their employees. According to the work ethics, leaders are accountable to the wellbeing of their employees and should never come a time when they leave this responsibility. They would instead initiate programs for training to make the employees more independent and easy to manage, and the best programs will be designed when there sufficient knowledge about the workplace. Inspect the workplace Regula r inspection of the workplace and the associated systems forms the platform for the management to make effective decisions concerning health and safety. This is because recommendations such as training originate from the findings of an inspection exercise. The human resource has the role of collecting as much information as possible about the experience and perceptions of the employees on their places of work. Although, the employees might require the organization to provide a healthy and safe environment, it is not true that most of them know the ideal working environment. Certainly, they are not much aware of the health and security issue surrounding their working environment. This is because, as any other person who becomes used to the same place, the employees tend to assume the many signs of risks. Regular inspections may also awaken the realization in the employees that the organization in concerned and become more responsible when working. In fact many accidents and errors le ading to health hazards resulting from the carelessness of the employees can be reduced through regular inspection. Aware that the management has played its role in ensuring health and securities, the employees are challenged to contribute to the dilemma.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More As human beings, the employees cannot sit down and watch everything being done for the sake of their wellbeing. They will indeed be motivated to rise up and take their respective roles and for the conditions beyond their control, they will be able to press their needs forward in faith that they will be dealt with. Their moral authority will move others and the entire organization towards protecting their health and safety. Conclusion Protecting the safety and health of the employees is an effort that calls for corporation from all the parties involved. Their commitment and especially that of the human resource management ensures that the employees have accessibility to the appropriate means. These means which are facilitated by the organization at large must meet a workforce which is prepared to exploit them. Therefore, training becomes important in preparing the employees to work independently towards a healthy and safe environment. In addition, the regular inspection of the workin g environment enables the management to make better decisions while at the same time encouraging the employees to take responsibilities. Despite their understanding of the situation, there is no way that the employees can ensure healthy and safe environment on their own.

How to Change a Column Size or Type in MySQL

How to Change a Column Size or Type in MySQL Just because you made a MySQL column one type or size doesnt mean that it has to stay that way. Changing the column type or size in an existing database is simple.​ Changing a Database Column Size and Type You change a column size or type in MySQL using the  ALTER TABLE  and  MODIFY commands together to make the change.   Lets say, for example, that you have a column named State on a table named Address and you previously set it up to hold two characters, expecting people to use 2-character state abbreviations. You find that several people entered entire names instead of 2-character abbreviations, and you want to allow them to do this. You need to make this column larger to allow the full state names to fit. Here is how you do it:   ALTER TABLE address MODIFY state VARCHAR(20) ; In generic terms, you use the ALTER TABLE command followed by the table name, then the  MODIFY command followed by the column name and new type and size. Here is an example:   ALTER TABLE tablename  MODIFY columnname  VARCHAR(20) ; The maximum width of the column is determined by the number in parentheses. The type is identified  by VARCHAR as being a variable character field. About VARCHAR The VARCHAR(20) in the examples can change to whatever number is appropriate for your column. VARCHAR is a character string of variable length. The maximum length- in this example  it is 20- indicates the maximum number of characters you want to store in the column. VARCHAR(25) could store up to 25 characters. Other Uses for ALTER TABLE The ALTER TABLE  command can also be used to add a new column to a table or to remove an entire column and all its data from a table. For example to add a column, use:   ALTER TABLE table_name   ADD column_name datatype To delete a column, use:   ALTER TABLE table_name   DROP COLUMN column_name

Capital and unskilled labor are substitutes Essay

Capital and unskilled labor are substitutes - Essay Example These are the factors that facilitate the growth development and expansion of a business. One would therefore have to understand the importance of labor in maintaining the production of more capital for a business. There is an immense similarity between the capital invested in a project and the type of labor it can afford to hire. This is also determined by the materials used by the business as it grows and ensuring that it rises. Production takes place when all the integral parts of an organization or business work together to attain a goal that will contribute to the whole company as well. It is particularly through these social relations to each other that that each part influences the other (Krusell 2000). These interactions between the manufacturers and the atmosphere within which they trade tasks and contribute to the complete construction usually differ depending on the nature of the method of production. Capital also involves the exchange values. It is hence a computation of property, trade ethics and social extent. It maintains its value regardless of the form in which it is invested in. Basically; capital always has a constant value of exchange. For instance, if the capital is in the form of land the exchange value will still remain the same. The commodity may appreciate or depreciate in value but during transformation its exchange value will not be altered. This shows that all factors are interrelated in one way or another so as to produce an end result that favors each integral part of the system (Johnson 1997). A laborer will receive a mode of survival in return for his services. Substitution of capital with unskilled labor would depend on how much initial capital was invested. Low capital investment would not enable employment of skilled labor as this would reflect unrealistic allocation of finances. Therefore, low capital investments will lead to employment of unskilled labor. A workforce that does not have adequate skills would
