Animal Abuse Essay Example for Free

Animal Abuse Essay The Greyhound is an ancient breed of dog. It is the only dog mentioned in the Bible, and has been depicted in many ancient Egyptian paintings, dating back over 4,000 years. Greyhounds were so revered, that the Greyhounds were allowed to share their tents. In ancient Arabic countries, the birth of a son was the most important event, the second was the birth of a Greyhound. The history of dog racing can be traced back to Queen Elizabeth I in the 16th century when Greyhounds were brought over to England from Egypt, where her majesty created the first formal rules of dog coursing, naming it the â€Å"Sport of Queens†. In the 18th century, England exported the sport to America, and soon the sport was comprised of racing and gambling. In 1912, the dog racing as it is known today, was established by Owen Patrick Smith, the man who invented the mechanical lure used in today’s dog racing. The first official dog track was opened in 1919 in California, and in 1931, wagering was legalized in Florida, paving the way for the development of the Palm Beach Kennel Club. The Palm Beach Kennel Club operated permits for dog racing, which officially started in America in 1932. Unfortunately, the once grandeur and majesty of the sport is tarnished with the unethical abuse these animals endure. The definition of animal abuse is â€Å"the crime of inflicting physical pain, suffering or death on an animal, usually a tame one, beyond necessity for normal discipline. It can include neglect that is so monstrous (withholding food and water) that the animal has suffered, died or been put in imminent danger of death. † (Hill, 2005). Many Greyhounds are the subject of abuse in the racing world. The Greyhounds are subject to horrible conditions. Many people enjoy watching a good race. The anticipation of the race and the thrill of their prized dog winning would make anyone want to attend a race. But it’s what happens before and after the race that has many people up in arms over the whole dog racing scene. When the dogs are not racing, they are kept in crates stacked one on top of the other. The dogs are not exercised regularly; the only exercise they get is from racing, and a race lasts for only a few minutes. If an Greyhound is injured during practice or during the race, the dog is killed and ground up for food for the other dogs. Many Greyhounds also die during the race due to exhaustion and dehydration. It is important to address this issue because animal abuse is a crime, and most people who commit these heinous acts are never brought to justice. It is also important to understand why someone could harm an innocent animal. According to the ASPCA, there are three main reasons why someone would be cruel to animals in their article titled, Why people abuse animals. The first reason is that some people abuse animals is that they do not know they are abusing the animal. Some people just don’t think about what they are doing to the animal, and others think excessive force is necessary to maintain control of the animal. A person who hits their dog when he or she does something wrong, like poop in the house, will use excessive force to show the animal that what he or she did was bad. Other people forget to roll down a window on a hot day with the animal in the car. The second reason a person would abuse animals is that the person will do it purposefully, but not for a continuous amount of time. Young kids who throw rocks at cats or kick a dog are an example of this type of abuser. Many young children can be taught through support groups and educational programs to show how an animal feels when it is abused in such a way, and many children learn to respect animals. The third reason a person would abuse an animal is the most serious form of animal cruelty. The third reason a person would abuse an animal is for power. Many of these types of people enjoy hurting the weak and helpless animals, as it makes them feel in control. Most of these people who intentionally hurt an animal have serious psychological issues that need to be addressed. If left unchecked, these issues may lead to more serious acts of violence. According the article, most people that were mentioned in the first and second reason for animal abuse can be educated through materials, counselors and educational classes. But even with the educational classes, what most people don’t understand is the psychological effects of the abuse has on animals. All animals want is to be loved and cared for, especially dogs. Humans have breed dogs to be our companions, and are the only animal that sets out to please us. When a human abuses an animal, we lose that trust that the animal places in us. The main psychological effect abuse has on dogs can be devastating. A dog may feel threatened by any human that it comes in contact with, and the dog can turn aggressive out of fear. Other dogs are fearful and maintain their fearfulness throughout the rest of their lives. These dogs may cower away from humans, shunning away when a human has an object in their hand or hide when they hear raised voices. L. Kalef wrote an article titled Psychological effects of animal cruelty, and in the article, he talked about the effects of animal abuse in Eastern Europe. For those who have traveled to Eastern European countries, it is not uncommon to be privy to packs of dogs roaming in some of the major cities, and sometimes being aggressive out of fear, hunger or abuse have led to provoke a similar reaction by the population by way of harm and abuse. Sadly, these neglected animals are under constant scrutiny and possible attack, which has become all too common. For years, welfare activists have been speaking up for the plight of the strays and the brutal inhumane abuse and killings; but no one until now has suggested that the constant exposure of this violence may instigate other and further violent activity within the community. In other words, growing up in a society being exposed to animal abuse causes further abuse and lack of compassion. (Kalef, 2012) But there are many people who argue that dog racing is not the only animal sport that has animal abuse and that it is part of the sport. Throughout the world of animal sports, there are some instances of animal abuse. In Mexico, bullfighting is a very popular sport, where the object of the game is to kill the bull or else the Matador will be stampeded or stabbed by the bulls horns. The bulls are starved and tortured, and they meaner the bull becomes, the more entertaining the sport. Also, horse racing has had its fair share of animal abuse cases. Many Thoroughbreds that receive an injury are killed, just like the Greyhounds, and made into meat that is sold for human consumption. J. Frater wrote an article titled 10 Debated acts of animal cruelty, which outlines a few instances that can be considered animal abuse. For those who have traveled to Eastern European countries, it is not uncommon to be privy to packs of dogs roaming in some of the major cities, and sometimes being aggressive out of fear, hunger or abuse have led to provoke a similar reaction by the population by way of harm and abuse. Sadly, these neglected animals are under constant scrutiny and possible attack, which has become all too common.

In other words, growing up in a society being exposed to animal abuse causes further abuse and lack of compassion. (Frater, 2010). But to most people, that is just the way the sport is. What is someone going to do with a prized race horse that has a broken leg and can no longer race? Why take the money to fix the injury, when the owner can make money off of selling the animal for food? It’s just part of the sport. But there is one question that needs to be answered. Which side is right? The truth is both sides are right. There will always be animal abuse in sports, as well as throughout the world. We as a people will not be able to completely stop the abuse, we can just diminish the amount of animals are abused. Through the use of stricter laws and more regulations, we as humans can help the voiceless. In conclusion, though there is no one way to solve animal cruelty in the world. There will always be animal cruelty in the sporting world, but as long as we humans can educate the younger generations, the amount of cases of animal cruelty will drastically decrease. Only one can hope that the â€Å"Sport of Queens† can return once again to the grandeur and majesty that the sport once was.

Macbeth :: essays research papers

MACBETH The play Macbeth by William Shakespeare contains many interesting themes; Shakespeare has taken a time of great change in Scottish history and used it to suit his of purposes. He uses the rise to power of a man to examine issues and ideology of Elizabethan times. The people of the Elizabethan timer believed in the divine right of kings, to put simply the king is gods chosen representative on earth, he speaks to god, to kill a king would bring about horrendous repercussions an turn a peaceful world into chaos. A good example of this chaos is when Macbeth kills Duncan; the day after Ross tells us That the day became as dark as night, a falcon was killed by an owl and that Duncan's horses turned wild and ate each other. Another theme from Macbeth, which is linked to the idea of divine right of kings, is Individuals disrupting the natural order of events. Unnatural acts such as murder and witchcraft are linked to unnatural events in nature. Using the example of duncan's horses, we see, after Macbeth committed an unnatural act (killing Duncan) we learn that his horses ate each other an act that is not natural to horses. Considering both of these, Macbeth had to decide whether it was right for him to change events, but also if he kills Duncan will it mean he, himself may fall victim to someone's vaulting ambition. "Bloody instructions which, being taught, return to plague the inventor" Macbeth Act 1 scene 4 Macbeth is also plagued with the idea of kingship. A bad leader will always equal unhappy times. When Maclom lists the qualities in a king ( Act 4 scene 3)he lists Justice, Verity, Temperance, Stableness, bounty, Perseverance, Mercy, lowliness, Devotion, Patience, Courage, Fortitude. How many of these qualities do we see in Macbeth? The role of good and evil, another major theme in Macbeth is important, because although Macbeth and lady macbeth are comsidered evil, they show weaknessess. It is clear they have got in to deep. I consider the witches to be evil as they corrupted a good man leading him from the values he was brought up to respecthowerve, I do not see Banquo as good. For the reason he did not voice his beliefs that macbeth was the killer, nor Macduff, although he appears as a good man he did abandon his family, leaving them to the wrath and injustice of Macbeth Macbeth :: essays research papers MACBETH The play Macbeth by William Shakespeare contains many interesting themes; Shakespeare has taken a time of great change in Scottish history and used it to suit his of purposes.

There are number of data compression algorithms, which are dedicated to compress different data formats. Even for a single data type there are number of different compression algorithms, which use different approaches. This paper examines lossless data compression algorithms. 1. DATA COMPRESSION: In computer science  data compression  involves  encoding  information  using fewer  bits  than the original representation.Compression is useful because it helps reduce the consumption of resources such as data space or transmission  capacity. Because compressed data must be decompressed to be used, this extra processing imposes computational or other costs through decompression. 1. 1 Classification of Compression: a) Static/non-adaptive compressio n. b) Dynamic/adaptive compressioin. a) Static/Non-adaptive Compression: A  static  method is one in which the mapping from the set of messages to the set of codewords is fixed before transmission begins, so that a given message is represented by the same codeword every time it appears in the message ensemble.The classic static defined-word scheme is Huffman coding. b) Dynamic/adaptive compression: A code is  dynamic  if the mapping from the set of messages to the set of codewords changes over time. 2. 2 Data Compression Methods: 1) Losseless Compression: Lossless compression reduces bits by identifying and eliminating  statistical redundancy. No information is lost in Lossless compression is possible because most real-world data has statistical redundancy. For example, an image may have areas of colour that do not change over several pixels; instead of coding â€Å"red pixel, red pixel, †¦ the data may be encoded as â€Å"279 red pixels†. Lossless compression is used in cases where it is important that the original and the decompressed data be identical, or where deviations from the original data could be deleterious. Typical examples are executable programs, text documents, and source code. Some image file formats, like  PNG  or  GIF, use only lossless compression 2) Loosy Compression: In information technology, lossy compression is a data encoding method that compresses data by discarding (losing) some of it. The procedure aims to inimize the amount of data that needs to be held, handled, and/or transmitted by a computer. Lossy compression is most commonly used to compress multimedia data (audio, video, and still images), especially in applications such as streaming media and internet telephony. If we take a photo of a sunset over the sea, for example there are going to be groups of pixels with the same colour value, which can be reduced. Lossy algorithms tend to be more complex, as a result they achieve better results for bitma ps and can accommodate for the lose of data. The compressed file is an estimation of the original data.One of the disadvantages of lossy compression is that if the compressed file keeps being compressed, then the quality will degraded drastically. 2. Lossless Compression Algorithms: 2. 1 Run-Length Encoding(RLE): RLE stands for Run Length Encoding. It is a lossless algorithm that only offers decent compression ratios in specific types of data. How RLE works: RLE is probably the easiest compression algorithm. It replaces sequences of the same data values within a file by a count number and a single value. Suppose the following string of data (17 bytes) has to be compressed: ABBBBBBBBBCDEEEEFUsing RLE compression, the compressed file takes up 10 bytes and could look like this: A 8B C D 4E F 2. 1. 1 Algorithm: for (i=0;i

The Rate Of Mental Health Essay - 1439 Words

In this essay, research based around the rate of mental health in UK students will be discussed and analyzed. The writer will be discussing how prevalent mental health conditions are in UK students and how research has helped to impact the support of students with such conditions. According to the World Health Organization a mental illness is â€Å"generally characterized by some combination of abnormal thoughts, emotions, behavior and relationships with others†. A big problem with mental illness is defining what behaviors are normal and abnormal as to do so it involves a judgment, but societies ideas of what is â€Å"normal† are subjective. There are a variety of mental health illnesses and according to the DSM-5 there are 271 psychological disorders which it has listed and categorized into groups such as eating disorders and mood disorders. The DSM-5 is a manual for diagnosing psychological disorders and aims to help professionals make objective decisions when diagnosing people with disorders, and although is widely used, it does focus a large amount on surface behaviors and not enough on what is causing people to act and or think a certain way. The DSM-5 also relies a lot on symptoms for putting people into categories for their maldaptive beha viors but, in reality mental health conditions are a lot more complicated - â€Å"a person may have some of the symptoms of one disorder and some of the symptoms of another and their symptoms may change in different surroundings† (Dalal andShow MoreRelatedThe Epidemic Rates Of Mental Health Concerns844 Words   |  4 PagesThere exists a limited amount of research in the field of child and youth mental health despite the high level of documented need in this area (Nadeau, Rousseau Measham, 2012).
