Free Essays on Sea Turtles

Sea turtles are generally solitary creatures that remain submerged for much of the time they are at sea. There are five species of sea turtles. They live in shallow, warm, coastal waters. They formation of forelegs that are shaped like paddles makes them excellent swimmers but slow walkers. They are large animals that live 15 to 30 years. The Leatherback is the largest turtle that averages 90 kg. There were some recorded up to 550 kg. The so called green turtles feed on sea grass but others eat invertebrates including jellyfish. When it is not nesting season, sea turtles may migrate hundreds or even thousands of miles. The evidence suggests that their navigation works by sensing wave motions of the earth’s magnetic field. Sea turtles can sleep at the surface while in deep water or on the bottom wedged under rocks in near-shore waters. Green turtles have been seen sleeping under ledges in reefs and rocks. The mating for most sea turtles are believed to occur during a limited "r eceptive" period prior to the female's first nesting emergence. Afterwards, only females come ashore to nest. It was proven with DNA that females return to the beaches where they were born to lay their own eggs. Males almost never return to land once they leave the sand of their natal beach. Copulation can take place either on the surface or under water. Sometimes several males will compete for females and may even fight each other. Females may mate with several males just prior to nesting season and store the sperm for several months. When she finally lays her eggs, they will have been fertilized by a variety of males. This behavior may help keep genetic diversity high in the population. They can lay up to 100 eggs at a time in sand above the high tide lines. The eggs are always in danger of being eaten by dogs, crabs or other animals. After laying the eggs, the female returns to the coastal shallow water. After about 60 days of incubation, the hatchlings move t...

Analytical Essay Sample on Roll of Thunder, Hear My Cry to Explore Racism

Analytical Essay Sample on Roll of Thunder, Hear My Cry to Explore Racism Over many years racism has been a disgusting, horrible issue in our world. Racism still exists today, although it is not as bad as it once was. In the historical novel, Roll of Thunder, Hear my Cry, Mildred D. Taylor explores the issue of racism through the victimization of the Berry Family and Sam Tatum by the Ku Klux Klan as well as an encounter with more disgusting people at the Wallace store. The Berry’s burning is a huge act for racism. First Mr. Berry was talking to a Caucasian lady. Then some man saw him talking to her. They didn’t think it was normal for an African-American man to be talking to and Caucasian lady. After Mr. Berry was done talking to her, he left for home in his car. But what Mr. Berry didn’t notice was that the Caucasian men were following him to his home. Mr. Berry didn’t have much gas left so he stopped at his friends’ house. As he was leaving his car to go to the house, The KKK jumped him and poured hot tar on him and feathered him. The KKK thought that you could only talk to your own race. Cassie also had some experiences of racism in Strawberry. Cassies experiences in Strawberry were very rough. First Cassie, Stacy, and T.J. went into Jim Lee Barnett mercantile buy some supplies for T.J.’s family. Mr. Barnett was helping the kids when a Caucasian lady came in. Mr. Barnett dropped all the things that he was helping with the kids and helped the lady, although the kids were first. So Cassie gets very upset and complains to Mr. Barnett. Then Mr. Barnett throws Cassie out of the store. That was the fist sign of racism Cassie experienced in Strawberry. The next experience was on the street of Strawberry. Cassie was minding her own business, when bratty Lillian Jean bumped in to Cassie. Well Lillian jean blamed the accident on Cassie although she did not do it. Lillian Jean made Cassie apologize, but Cassie did not. So Lillian Jean made her dad tell her to apologize just because Cassie. Whit this racism, the KKK is a big part of racism, so is the Wallace store. The Wallace store is not a good place for kids to go and hang out. Papa doesn’t want the kids to go to the Wallace store because the Wallace’s are members of the KKK and the kids there are drinking. The KKK might harm the kids or even kill them because they are African-American. So that is why Papa doesn’t want the kids to go there. This is another act of repeating racism. Killing or harming African-American kids just because the kids go to a Caucasian store. By reading Roll of Thunder, Hear my Cry, Mildred D. Taylor wanted us to realize racism is unacceptable, evil, inappropriate and not necessary. Our job is to stamp out racism by treating every human being equally. It is important to join together to create a nation that celebrates our differences.

The Myth of Secure Computing by Austin and Christopher Article

The Myth of Secure Computing by Austin and Christopher - Article Example The amount of money spent on digital security is only 5 to 10 percent of a company’s total expenditure due to which, there are risky security concerns. Network Attacks, which are responsible for slowing network functions and disrupting online performance, are common threats to digital security that can result in big financial losses for the company. Network attacks are external. Intrusions are internal attacks and are more dangerous than network attacks as the intruders can use the same rights to alter or damage data as authorized users. Intrusions can cause not only monetary but also data leakage loss. All kinds of threats are highly dangerous and need to be analyzed in advance. The IT department of a company needs to be highly effective in identifying all kinds of threats and the level of security that should be provided to each and every asset. An operational approach needs to be followed in order to secure the company, its assets and its reputation from any digital security breach. Risk management should be there in order to check the possible risks to a company’s digital security and to control them in time. The IT department is required to keep continuous check to day-to-day processing. If software programs are used in a company, they must be tested regularly. The coding, testing and implementation process should not be conducted with proper care and efficiency. The IT staff should be well equipped with all concerned knowledge about IT state of the company and required security measures. The writers of the article have pointed towards a crucial issue that needs attention to detail. The companies working today are computerized mostly and have their own networks due to which, they are in need of digital security measures so that they face minimum security breaches and can control any intrusion in order to save them from big losses.  

Children, War and Education Essay Example | Topics and Well Written Essays - 1000 words

Children, War and Education - Essay Example This leads them into an intense mental trauma. 3. Children used as terrorists/soldiers:The scene grows even more gruesome when children are made a part of these wars. Their small hands are trained to hold and control the agents of deaths deadly weapons and their vulnerable minds are inculcated with norms of the terror culture where ruthless massacres are a way of life. Be it the Hamas in Gaza, the Taliban in Afghanisthan or the LTTE in Sri Lanka they extensively use children as terrorists."assessments by the Sri Lankan Directorate of Military Intelligence have estimated that as much as 60 per cent of the LTTE's fighters were below 18."(SOUTH ASIA TERRORISM PORTAL) and "LTTE terrorists used a 13 year old child suicide bomber against the advancing 55 Division troops in Chalai "( Thilakaratne 2009)The conditions are no different in Jammu and Kashmir where children are used as "terror tools". They are even trained in throwing grenades and planting IEDs.( GUPTA 2005).This affects a child's(terrorist) psychology in a very dangerous ma nner sometimes making it impossible to help them lead a normal life even after they have been freed/rescued. Their experience with terror creates a kind of crisis in their life - it's a crisis of life purpose and direction. Children Participation in armed conflicts, even voluntarily, is an offence as per the Geneva Convention (1948), its two amendments (1997), and as per Article 38 of the UN Convention on Rights of the Child. But one can definitely not expect the terrorist groups to abide by these laws. Even in cases where terrorist outfits were warned against the use of children or even when the terrorist groups promise not to use children (as in case of LTTE), there are hardly any productive or positive results. 4. Loss of children's education: In conditions like these it's not difficult to imagine what must be happening to the education of children. A country's civilian population is under a condition of constant stress when there is a war going on at the borders of the country and the education of children is often disturbed due to falling attendance as a result of fear, shutting down of schools due to govt. orders concerning safety or other such reasons. And the conditions worsen in countries where there are no defined battle fields and the civilian areas are frequently attacked. Terrorist attack on schools causes a great damage; and this damage is multidimensional. Not only is the property damaged but also many lives are lost and the entire education system completely disrupted and sometimes even uprooted. Attacking schools severs several purposes for the terrorist organisations: A. Schools are soft targets and can be attacked comparatively easily.(Ervin 2006) B. Attack on

Quality management focuses attention on continuous improvement Essay Example for Free

Quality management focuses attention on continuous improvement Essay Th e work of W. Edwards Deming is a cornerstone of the quality movement in management. 27 His story began in 1951, when he was invited to Japan to explain quality control techniques that had been developed in the United States. â€Å"When Deming spoke,† we might say, â€Å"the Japanese listened. † Th e principles he taught the Japanese were straightforward, and they worked: Tally defects, analyze and trace them to the source, make corrections, and keep a record of what happens afterward. Deming’s approach to quality emphasizes constant innovation, use of statistical methods, and commitment to training in the fundamentals of quality assurance. One outgrowth of Deming’s work was the emergence of total quality management, or TQM. Th is process makes quality principles part of the organization’s strategic objectives, applying them to all aspects of operations and striving to meet customers’ needs by doing things right the fi rst time. Most TQM approaches begin with an insistence that the total quality commitment applies to everyone in an organization, from resource acquisition and supply chain management, through production and into the distribution of fi nished goods and services, and ultimately to customer relationship management. The search for and commitment to quality is now tied to the emphasis modern management gives to the notion of continuous improvement—always looking for new ways to improve on current performance. 29 Th e goal is that one can never be satisfi ed; something always can and should be improved upon. Evidence-based management seeks hard facts about what really works. Looking back on the historical foundations of management, one thing that stands out is criticism by today’s scholars of the scientifi c rigor of some historical cornerstones, among them Taylor’s scientifi c management approach and the Hawthorne studies. The worry is that we may be too quick in accepting as factual the results of studies that are based on weak or even shoddy empirical evidence. And if the studies are fl awed, perhaps more care needs to be exercised when trying to apply their insights to improve management practices. Th is problem isn’t limited to the distant past. 30 A book by Jim Collins, Good to Great, achieved great acclaim and best-seller status for its depiction of highly successful organizations. But Collins’s methods and fi ndings have since been criticized by researchers. 32 And after problems appeared at many fi rms previously considered by him to be â€Å"great,† he wrote a follow-up book called How the Mighty Fall. 33 Th e point here is not to discredit what keen observers of management practice like Collins and others report. But it is meant to make you cautious and a bit skeptical when it comes to separating fads from facts and conjecture from informed insight. Today’s management scholars are trying to move beyond generalized impressions of excellence to understand more empirically the characteristics of high-performance organizations—ones that consistently achieve highperformance results while also creating high quality-of-work-life environments for their employees. Following this line of thinking, Jeff rey Pfeff er and Robert Sutton make the case for evidence-based management, or EBM. Th is is the process of making management decisions on â€Å"hard facts†Ã¢â‚¬â€that is, about what really works—rather than on â€Å"dangerous half-truths†Ã¢â‚¬â€things that sound good but lack empirical substantiation. Using data from a sample of some 1,000 fi rms, for example, Pfeff er and a colleague found that fi rms using a mix of well selected human resource management practices had more sales and higher profi ts per employee than those that didn’t. 35 Th ose practices included employment security, selective hiring, self-managed teams, high wages based on performance merit, training and skill development, minimal status diff erences, and shared information. Examples of other EBM fi ndings include challenging goals accepted by an employee are likely to result in high performance, and that unstructured employment interviews are unlikely to result in the best person being hired to fi ll a vacant position. 36 Scholars pursue a variety of solid empirical studies using proven scientifi c methods in many areas of management research. Some carve out new and innovative territories, while others build upon and extend knowledge that has come down through the history of management thought. By staying abreast of such

Hemingway :: ESSAYS

Hemingway In one of the chapters in the book entitled â€Å"Hemingway† the author Leo Lania tries to explain Hemingway and his work. He explains that a key to understanding Hemingway can be found in the characters of his heroes and in their beliefs. The leading character â€Å"appears in various guises in the different novels and short stories but basically he is always the same type†(Lania8).Whether ordinary soldier or general, smuggler or gambler, Negro or journalist he is a man scarred by experience. He has always been gravely wounded, physically or mentally, either during the war, in the sports arena, during childhood, in fight for existence. At some time or other something terrible has happened to him and the memory persecutes him. Lania also explains that Hemmingway’s principal character is almost always an American from the Middle West. He is â€Å"no intellectual but his primitiveness is only a mask for his sensitivity. In order to master life he needs a moral code he can follow, a believe in certain rules by which to measure his behavior†(11). Neither books, reason nor religion can supply him with this belief. He needs to practical experience. Hemingway’s’ world is at war, â€Å"war either in the literal sense or the ruthless, brutal fight for existence†(11). In short stories Hemingway sums up his philosophy of life in one sentence: ‘A man can be destroyed but not defeated’ â€Å"the speaker is an old bullfighter who although overcomes, does not surrender and therefore proves the victor†(11). In another story a champion boxer provides a similar example. In his latest work, The Old Man and the Sea, the old Cuban fisherman triumphs through tenacity of his fight with the great fish, although in the end the sharks eat away his catch and deprive him of the reward for his indescribable sacrifice. This theme runs continuous through all of Hemingway’s works. â€Å"His outlook may be limited and incomplete, his conception of honor and heroes primitive, even childish†(12). The part played by women in Hemingway’s work is significant. That he handles sex without sentimentality that only strict moralists would hold against him. This was no t only part of his poetic license but also an important contribution to our knowledge us. Hemingway’s lovers â€Å"have nothing in common either spiritually or intellectually, nor do they seek it†(14). They are not partners they are not even enemies. Their relationship is therefore neither exalted nor tragic.

Black American Music History Essay

First of all, there is many different types of African American music but im going to talk about three in particular which are slave spirituals, blues, and the more common rap/hip-hop. First slave spirituals is a type of religious song originating among black slaves in the American south. It was famous for the reason that the lyrics of negro spirituals were tightly linked with the lives of their authors†¦. slaves! While work songs only dealt with their daily life, spirituals were inspired by the message of Jesus Christ and his Good News (Gospel) of the Bible, â€Å"You can be saved†!

Blues is a type of folk song devised by Black Americans at the beginning of the 20th century. Blues was so important to the African Slaves because it was a sort of code, how they told stories that had things to do with their owner and everyday life. Lastly is the most common now in time some people know it as rap others as hip hop but it is the style and fashion of African American music. Hip hop is important to African American culture because it originated from it all started when blues and jazz crossed over and musicians started making beats which were call bebop.
