The Great Gatsby vs. Hamlet - 1514 Words
Throughout history, the media has shown many different sides of love. Weather it be peaceful, violent, dangerous, beautiful, almost all forms of the media have shown love in some way. In the novel The Great Gatsby, love is shown between many different characters in different ways. The reader experiences love at its best and worst. We see relationships flourish, rekindle and end between the different characters. The most controversial relationship is the relationship between Daisy and Tom. Through infidelity, and mistrust, tragedy occurs. Other characters become associated with their marital problems, showing different kinds of love and relationships. In the play Hamlet, the reader also experiences many different kinds of love, ranging fromâ⬠¦show more contentâ⬠¦Both pieces of literature express the same theme of love and corruption. In the play Hamlet, the relationships between the different characters were destroyed because of Hamlets frustrations and other characters suspicions. Hamlet and Ophelia once had a very passionate love affair. Ophelias father Polonius and brother Laertes did not agree with their relationship. Laertes told Ophelia that she could not have a relationship with Hamlet because For Hamlet and the trifling of his favour, Hold it a fashion and a toy in blood, A violet in the youth of primy nature, Forward, not permanent, sweet, not lasting, The perfume and suppliance of a minute; No more. Act I scene III 3 Laertes is implying that Hamlet is not the right age for her, and he is comparing Hamlets love of Ophelia to the violet, which flowers early in the spring, but doesnt live long. If it were not for Polonius and Laertess influence on Ophelia, and Ophelias willingness to go along with everything her father and brother tell her to do, many tragedies could have been avoided such as Hamlets insan ity, and the death of most of the main characters. The relationship between Gertrude and Claudius caused many problems. Gertrudes husband King Hamlet was killed, and the reader learns that it was Claudius that killed King Hamlet in act I scene V. Two months later, Claudius and Gertrude married, and Hamlet was not happy.

The Universal Declaration Of Human Rights - 1103 Words
In 10 December 1948 ââ¬Å"The Universal declaration of human rightsâ⬠was declared to protect the freedom of every human being of the planet. These human rights were declared as the foundation of freedom, justice and peace in the world. After World War II, a committee heated by Mrs. Roosevelt wrote a special document and its main purpose was to bring peace around the world. Although human rights was declared to give freedom and rights to every living being in the planet, I claim that not all of the human right is protected, one of which I believe is violation of womenââ¬â¢s right because of gender discrimination, education and increasing women poverty and violence against women. Firstly, Gender discrimination refers to discrimination, which is based on sex of the person. In todays society it often affects the girls and women in the society and predominantly an issue for women. It is not only prevail in a country but all around the globe. According to the law, women and men should be treated equally, not only women and men but also all living creature should be treated with equality and respect. Women are one wheel of the society while the other wheels are men. According to The universal declaration of human rights Article 1, ââ¬Å"All human beings are born free and equal in dignity and rightsâ⬠however all the human rights are not protected.

Information Technology and protection of Malware â⬠Free Samples
Question: Discuss about the Information Technology and protection of Malware. Answer: Introduction Malware is the abbreviated term used for "malicious software". This is the software which is specifically developed to gain access or to damage a computer without any knowledge of the owner. Software is considered malicious based on the intent of the developer rather than the function the software performs. Malicious software's are developed to get personal information of the owner which may be of sheer importance to him. Initially malwares were developed for the purpose of experiments and pranks but with development in the technology now these malwares are now created to earn profit via forced advertisements (adware), stealing important information (spyware), spreading email spam (zombie computers) or for the purpose of money extortion (ransomware). Certain factors can make computer prone to malware attacks such as defects in operating system, running of computers on the same network etc. So it is very important to stay alerted from these type of malicious softwares (Skoudis Zeltse r, 2004; Elisan, 2012). Scope of Engagement The purpose of this report is to provide the reader with an insight on the concepts of malware and how its development took place with the years and how the technologies have been developed simultaneously to prevent unauthorized access to networks and computers. The report also discusses about how cyber criminals use this technology to their advantage and infect computers and how security applications have been developed to prevent the same. A brief history of the topic is also presented to provide the reader with a basic understanding about the issue of computer security. History The knowledge about viruses came into existence with publication of the research paper named "Computer Viruses-Theory and Experiments" which was written by Prof. Fred Cohen in 1984 in which he discussed about the potential of the viruses, how could they enter the system and what could be done to prevent them. He showed that the only systems that are safe from the attacks of the viruses were the systems with low or no sharing or has developed protection measures (Athina, 2012 ). Three years later in 1987 another computer specialist named Ralph Burger decided to investigate about the virus and he jotted down his research in the book titled "Computer Viruses: A High Tech Disease" (Virus Scan Software, 2017; Creutzburg, 2016). Publication of this book cause major problems in the sector of information technology. His research was so in depth that he even wrote about how the viruses worked and how they can be designed. This resulted in the sharing of knowledge of virus development among th e people who earlier had no or little idea about this technology. The book published by him acted as a beginner's guide of virus development and people started developing their own viruses for prank as well as for experiment purposes. With the introduction of modern internet in the 1990's the reporting's of security breach also increased (Radware, 2017). The new and modern viruses named Michelangelo and Melissa were the latest and the most dangerous addition to the world of viruses. The year also saw the development of new virus technology like bots and botnets (Landesman, 2017). With the development of modern internet for the first time the private and personal information of the people were exposed. This became a serious issue as it was getting hard to trace these notorious criminals and there were no measures taken or a force sanctioned to tackle these incidents. Eventually the problem was becoming a national security concern and not only the personal systems were affected but the systems with government were getting affected too. In the year 1998, the US attorney general passed a bill of $64 million to counter the problem of cyber-attacks. A command center was sanctioned to protect the systems on national as well as personal levels and in 1990 a Protection Center was introduced. With the development of internet, the security issues and the threat to the privacy is also increasing. With the change in preference of people and the shift towards cashless transactions and using digital methods instead of hard copies there is a need to develop proper measures t o protect people from malware and viruses. Initially only viruses were the only malicious software that posed threat but with the development of technology and internet many malwares developed with time. Most common types of malwares are discussed below (Adaware, 2016; Miloevi?, 2013): Viruses - Virus is the type of malware that has potential to replicate itself and harm the computer. A virus accesses the code of the computer by executing its code. A virus generally targets executable files and applications. A virus is capable of damaging data files, hampering the performance of the system and corrupting the data stored on the system. Spyware - A spyware is used to spy on computers or any digital device running on a particular OS. It is often used in the form of adware which when clicked by the user enters the system and monitors the activity of the system. It is mainly used to gather the information about the financial systems and obtain sensitive data. Worms- A worm is a malware which replicates itself and occupies the data on the disk and hampers the performance of the computer through the network. Unlike a virus a virus does not need to attach itself to an executable file to replicate itself. Bots - A bot is a program that when released on a computer can access and control that computer from a remote server. This is generally used by hackers and can be released through the means of game or a software application. A computer can be controlled by a bot when the application is run on the system and then the remote server access and controls the system in the background. Trojans - A Trojan software is the one which disguises itself in form or other applications. A Trojan also known as Trojan horse slows down the process speed of the system, spies the activity and steals the information from the system. The software generally steals the information from the system and sends the data back to the hacker who developed the Trojan. Spam - A spam is generally targets a large group of systems. It is also used to steal personal and important information like credit card details and other information which may be of benefit to the person who sent the spam. A spam is sent in the form of tricky message or advertisements. Apart from the tools that the malware uses to interfere with personal data there are certain tools that have been developed to counter with these attacks and to help people to keep their personal information safe (Infosec, 2017). These tools are listed below (Comodo Antivirus, 2014; McAfee, 2017): Firewall- A firewall is software which acts like a barrier which prevents the infection from spreading. Firewall is the term used by fire fighters. It is a barrier which is used by them to stop the fire. Just like this in computing terms a firewall is software which checks the file for infection and then it allows the transfer of file to its desired destination. It is preferred in organization in which the data is shared on large scale. A firewall is generally installed in the main computer and then the data is allowed to be sent to other computer after the successful scan of the file. If there is no malicious file attached with the data, then only the firewall allows the sharing of the data (Noonan Dubrawsky, 2006). Antivirus software- Antivirus software scans the file and blocks and deletes any malware or viruses attached with the file. With the development of viruses, antivirus technologies have developed too and have been successful in dealing with the issue. Viruses though have always been a step ahead but antiviruses have always been the most reliable method to counter them. An antivirus program generally uses a two-step method to identify activities of malware. First it looks for suspicious activities in the system which doesnt occur normally and then in the next step it scans the whole system for malicious software. It identifies the virus by the set of database which is pre-installed by the software company in the software which has a unique method or prevention for every type of virus. If the software finds any unusual activity in the system, it pops up a security message and prompts the user to take a measure to counter the problem. Antivirus software is needed to be updated on a regul ar basis to keep up with various developments in the malicious world and so that the user can be protected. This is the main reason the antivirus software prompts the user to keep his system and database updated (Parsons Oja, 2012). Spam filter- There are many sites on the internet which contains spam and are malicious. These spams pose a worldwide threat to the security of the users. With spreading awareness and netizens getting educated many users are able to avoid these types of threats but still it sucks a small amount of users in it. It is very cheap to develop and it spreads very easily. A spam filter works in many ways and the most common way is that it scans and filters the spam in the e-mails. This method is effective but is time consuming too (Downing, 2015). Impact of Malware in Real Life A malware can do many things, from stealing personal info to destroying the performance of the computer. We have already discussed about the potential of malwares. Here is the list of the impact of malware if it enters your system (Visually, 2017; ClearPath IT Solutions, 2017): It can cause the system or the connection to slow down. In extreme conditions it can cause the system to crash and a person may lose his unsaved data. It can cause a message to be displayed continuously. It can cause serious trouble in shutting down and restarting of the computer as various programs will be still active. It can even hijack the browser and redirect the user to various sites. It can use your computer to broadcast various files and attacks. It can send e-mails which were not written by the user and can lend him into trouble. It can be invisible if designed well and can cause the harm in background without any knowledge of the user. Conclusion There are various security measures available to the user which can protect his system and him from the malware. Though there are many companies which are providing these services there are many notorious hackers who manage to stay one step ahead and stay trouble. This is a never ending fight between the two and it is required by the person to stay alerted in order to avoid any kind of harm to his personal information. Apart from this it is necessary for a user to install and update these anti malware programs on a regular basis so that they do not fall prey to cyber criminals. References Adaware.

Stereotypes Of Elderly Essays - Gerontology, Ageing, Stereotypes
Stereotypes Of Elderly The baby boomers cohort is soon approaching the last third of their lives while they try to disentangle the many stereotypes the elderly encounters today. The baby boomers are now beginning to attain a new vantage point about getting old. This is the first approaching age cohort in American society that is trying to make a difference with being able to accept the concept of growing old as the true so-called "golden years." The baby boom generation grew up primarily in the hippies decade which contributed to the vast majority of people to first become in American society freewill, liberal, independent individuals. Presently in society today the once "hippies" that rejected the advice of anyone over 30 are now beginning to educate themselves about what their future beholds as they begin to reach the last third of their lives. They want to focus on the reality of getting old not just the negative stereotypes society has created towards the elderly. In the American society we have created such negativism towards the elderly. The article points out that by time the tender age of only 6 years old we have created negative stereotypes about aging and we also develop stereotypes about races and gender at this same time. We feel in the American society almost as if it is a sin or even lack of a human being if we show signs of aging. The article discusses from the 1960s to the 1980s, the number of wrinkle removing face-lifts rose from 60,000 to an estimated 2 million a year at an annual cost of $10 billion. Due to this drastic increase pertaining to rejuvenation we should all become plastic surgeons. A diverse amount of experts are trying to change the way society views and deals with growing old. They have adopted the concept of "conscious aging." This new concept basically means trying to accept what aging actually is, and trying to view it as a new point of life- a "new window." Also, not concentrating on the inevitable primary aging characteristics is an essential way to live and cope with being old. If the elderly can learn to educate themselves about the process of aging, and not pinpoint it to just a change that they individually encounter alone, then they could possibly realize this happens to us all at one point in life. Therefore, we may not have such negative feelings about becoming old or even being old. If society can learn to obtain these attitudes towards being old maybe it will even become a self fulfilling prophecy as viewing the elderly from a new positive perspective.

The Detrimental Effects in Changing the Rent Contr Essays
The Detrimental Effects in Changing the Rent Contr Essays The Detrimental Effects in Changing the Rent Control Act Rent Control-pro The Detrimental Effects in Changing the Rent Control Act In a just society, the ruling authority must decide what is right when allocating wealth to its individual citizens. The same ruling authority does this by intervening with the inner workings of a marketplace to uphold its fundamental values and ideals. The aim of government intervention is to create a just society that will reflect the peoples values. Governing bodies do this by establishing laws that enforce fairness or equity. The Ontario government passed the Rent Control Act in 1975. The law levels the playing field between landlords and tenants. New units are exempt from controls for their first five years after which the controls are put into place. The controls put a ceiling on annual rent increases. Under current law, a landlord may only increase a tenants rent by 2% plus inflation.1 As with all other markets, the housing market is based on supply and demand. If the nature of the market were allowed to take its course, then the price of housing would become unaffordable for most citizens. An unfair situation would be created where power and money would be disproportionately appropriated to land owners. Rent control laws were established by previous governments to protect society and its people from inflated and uncontrollable housing costs. The Harris government now wants to repeal these laws. On June 25 the Minister of Housing, Al Leach, released a policy paper outlining the changes that are to be made to Ontarios rent laws. Conservative legislators plan to pass the proposed Tenant Protection Act in the fall. The omnibus legislation will rescind the Rent Control Act, the Landlord and Tenant Act, the Rental Housing Protection Act, Residents Rights Act, the Land Lease Statute Amendment Act, the Vital Services Act.2 The most objectionable change allows the act to lift controls off vacant units. The 3.2 million renters in Ontario are very concerned about the changes.3 The housing ministry will accept written submissions from the public until August 30. Public hearings are also planned in hope that they will ease the transition. However, most people are indignant towards the idea. Changing the rent control laws would be detrimental to society as they threaten citizens positive right to affordable housing, harm their mobility rights and increase the gap between the rich and the poor. The proposed Tenant Protection Act assaults peoples right to affordable housing. If people are to adhere to a basic standard of living, then the cost of their homes must be affordable. But what exactly is affordable? The Ministry of Housing released a report stating that 70,000 Toronto house holds (20% of the citys population) do not have affordable housing. The report explains that a tenants' housing is unaffordable if they are paying more than a quarter of their gross income in rent. This is an alarming thought since some renters are paying 70-80% of their gross income in rent.4 The problem of high housing costs is combated by rent control to allow people a minimum quality of life. Housing like medical care is not normal good or service. It is a basic need. Renters need to buy more than landlords need to sell. If the renter does not get a place to live, he is on the street. If the landlord has no tenant, he just has an empty apartment. In short, there is a mismatch of power in the rental market. The laws of supply and demand are unfairly applied against the buyer. Thus controls came into being precisely because the market does not work. Lifting controls would hurt peoples ability to bear the cost of housing without serious harm. The government justifies this action by arguing that something must be done about Torontos apartment shortage. Because apartments are offered below their market value, they are sold faster new ones can be created. Toronto has a vacancy rate of .8% with only twenty new apartment units built in Metro last year.5 Currently, two thirds of renters move once in five years. Since controls are lifted off vacant apartments, the government believes that after a few years, most apartments will be decontrolled and the supply problem would

Understanding Chemical Evolution
Understanding Chemical Evolution The term chemical evolution can be used in many different ways depending on the context of the words. If you are speaking to an astronomer, then it could be a discussion about how new elements are formed during supernovas. Chemists may believe chemical evolution pertains to how oxygen or hydrogen gases evolve out of some types of chemical reactions. In evolutionary biology, on the other hand, the term chemical evolution most often is used to describe the hypothesis that organic building blocks of life were created when inorganic molecules came together. Sometimes called abiogenesis, chemical evolution could be how life started on Earth. The Earths environment when it was first formed was very different than it is now. The Earth was somewhat hostile to life and so the creation of life on Earth did not come for billions of years after the Earth was first formed. Because of its ideal distance from the sun, the Earth is the only planet in our solar system that is capable of having liquid water in the orbits the planets are in now. This was the first step in chemical evolution to create life on Earth. The early Earth also did not have an atmosphere surrounding it to block ultraviolet rays which can be deadly to the cells that make up all life. Eventually, scientists believe a primitive atmosphere full of greenhouse gases like carbon dioxide and perhaps some methane and ammonia, but no oxygen. This became important later in the evolution of life on Earth as photosynthetic and chemosynthetic organisms used these substances to create energy. So just how did abiogenesis or chemical evolution happen? No one is completely certain, but there are many hypotheses. It is true that the only way new atoms of non-synthetic elements can be made are through the supernovas of extremely large stars. All other atoms of elements are recycled through various biogeochemical cycles. So either the elements were already on Earth when it was formed (presumably from the collection of space dust around an iron core), or they came to Earth via the continuous meteor strikes that were common before the protective atmosphere was formed. Once the inorganic elements were on Earth, most hypotheses agree that the chemical evolution of the organic building blocks of life began in the oceans. The majority of Earth is covered by the oceans. It is not a stretch to think that the inorganic molecules that would undergo chemical evolution would be floating around in the oceans. The question remains just how these chemicals evolved to become organic building blocks of life. This is where the different hypotheses branch off from each other. One of the more popular hypotheses says that the organic molecules were created by chance as the inorganic elements collided and bonded in the oceans. However, this is always met with resistance because statistically the chance of this happening is very small. Others have tried to recreate the conditions of early Earth and make organic molecules. One such experiment, commonly called the Primordial Soup experiment, was successful in creating the organic molecules out of inorganic elements in a lab setting. However, as we learn more about the ancient Earth, we have found out that not all of the molecules they used were actually around during that time. The search continues to learn more about chemical evolution and how it could have begun life on Earth. New discoveries are made on a regular basis that help scientists understand what was available and how things may have happened in this process. Hopefully one day scientists will be able to pinpoint how chemical evolution happened and a clearer picture of how life began on Earth will emerge.
