Artistically Hanging a Man - 1183 Words
A man, who wanted to join the Confederate army but wasnââ¬â¢t able to, set fire to Owl Creek Bridge which was a bridge the Union army was building. The punishment for this is to be hanged. This is a story of a manââ¬â¢s last thoughts while being hanged for committing a crime. This is the analysis of An Occurrence at Owl Creek Bridge. The author who wrote An Occurrence at Owl Creek Bridge is named Ambrose Bierce. Bierce lived from 1842 to about 1914 (ABAS: The Death of Bierce). Bierce disappeared somewhere in Mexico, so 1914 is only an estimate of when he died; his daughter, Helen, alarmed by his disappearance got the United States Government involved. (ABAS: The Death of Bierce) Some things in his life that seems to have influenced his story is the fact that he was in the Union Army, his two sons died, and a divorce from his wife (Bierce 551). This story states how the protagonist set fire to the Union Armyââ¬â¢s bridge, which is why the fact that Bierce was in the Union Arm y influenced that aspect of the story. The main characterââ¬â¢s thoughts during the story venture to his family which shows that Bierceââ¬â¢s family and regrets that he lost his family also influenced the story. Another thing that influenced this story is a place called Swan Creek Trestle in Northern Alabama, which looks just like the one described in the story.

Essay on Hamlet Act 3 Scene 1 To Be or Not To Be - 588 Words
Hamlet Act 3 Scene 1: Hamletââ¬â¢s ââ¬Å"To Be Or Not To Beâ⬠Soliloquy Hamletââ¬â¢s ââ¬Å"To be or not to beâ⬠soliloquy is conceivably the most prominent soliloquy in the archive of the theatre. Even now, more than 400 years after it was originally written there is still an air of familiarity that reaches others even if they do not know the play itself in detail. In act 3, scene 1, Hamletââ¬â¢s ââ¬Å"To be or not to beâ⬠Soliloquy is critical in developing the plot because this is when Hamlet discusses his most suicidal thoughts. The way that Shakespeare portrayed Hamletââ¬â¢s soliloquy touches on a global issue of suicide. While Hamlet considers his suicidal thoughts it reveals inklings about his character. Hamletââ¬â¢s soliloquy advances the tone of the play because ofâ⬠¦show more contentâ⬠¦95-98). In this scene Hamlet denies ever giving her gifts when he says ââ¬Å"No, not I. I never gave you aughtâ⬠(act 3.1. 99). This quote from Hamletââ¬â¢s soliloquy shows that his suicidal thought process affects his interaction with others. The fact that he claims that he never gave Ophelia any gifts and then insults him when she attempts to give him an explanation shows that Hamlet was not in the right frame of mind due to the fact that he is extremely suicidal and he just discovered that his father may have been murdered by his uncle. The rhetorical devices used in Hamletââ¬â¢s soliloquy help advance the plot are repetition and direction.These devices impact the overall effect by adding a contemplative tone. An example of repetition in this speech would be when Hamlet repeats the line ââ¬Å"to die, to sleepâ⬠(act 3.1. 61,65). another example of a rhetorical device would be when Hamlet says ââ¬Å"no traveler returns puzzles the will and makes us rather bear those ills we have than fly to those that we know not of?â⬠(act 3.1. 81-83). That is an example of direction in the play. These rhetorical devices help Hamlet develop the plot because they accentuate his point about whether he commit suicide or not. In Conclusion, In act 3 scene 1, Hamletââ¬â¢s ââ¬Å"To be or not to beâ⬠Soliloquy was critical in developing the plot because this was when Hamlet was at his most suicidal standpoint in the play.Show MoreRelatedAct 3 Scene 1 Of Hamlet1279 Words à |à 6 PagesIn Act 3 scene 1 of Hamlet we are faced with the soliloquy that contains one of the most famous lines from English literature: ââ¬Å"To be, or not to be ââ¬â that is the questionâ⬠(III.i.57). This passage tends to show a large amount of evidence of the theme ââ¬Å"Action vs. Contemplationâ⬠. Through poetic devices, tone, and sensory imagery we are able to analyze the theme and Hamletââ¬â¢s tragic flaw: indecisiveness/inability to act. Poetic devices are a great way to develop a point efficiently. Within Hamlets soliloquyRead MoreWhat Is The Adaptation Of Hamlet Act 3 Scene 11257 Words à |à 6 PagesAct 3 scene 1 of Hamlet as told by William Shakespeare shows Hamlets digression into depression. Within the words of the play, hides why Hamlet is moving into a depression. This is because of the death of his father. At a young age he lost his father, but not like any other person has. Hamlet Sr. was murdered by his own brother and then comes to his son to ask for him to avenge his death, by killing his uncle.

I believe that there is a lot of evidence arguing that Hamlet never loved Ophelia and that he was just using her.

Wix vs WordPress Which Is Better for You (Everything You Need to Know)
Creating a website has never been a task for the faint of heart. Even the simplest site will require time, money, and know-how to steer it in the right direction. Thats where Wix vs WordPress come into play.Or at least, that used to be the case, until websiteà builders and Content Management Systems (CMS) took the web by storm, including the two titular platforms. Wix and WordPress two very different tools which share one common goal: enabling users to create stunning and usable websites in a simple manner.In the spirit of healthy competition, well be pitting Wix vs WordPress to measure how they perform against each other in four different categories. In the end only one will remain, so lets get the fight started!Wix vs WordPress1. Ease of useGetting started on Wix is a simple process. Once youve signed up, it will ask you what kind of website you want to create, and then it will send you right over to its collection of templates for your chosenà category.After making your choic e you can begin tinkering with it using Wixs colorful drag-and-drop editor. You can create new pages using a drop-down menu without leaving the editor, and switch between them in a matter of seconds.Moving onto WordPress, taking your first steps with the CMS can be a little intimidating, since it doesnt hold your hand too much. While there are thousands of articles and tutorials covering every simple step of the process ââ¬â from creating new pages to choosing the right theme ââ¬â getting to know WordPress ins and outs can take a while.WordPress 0 : Wix 1 The first round of the Wix vs WordPress fight goes to Wix, which has you up and running in no time at all.2. Depth of CustomizationFor this round, well take into consideration two aspects: design customization, and the ability to implement advanced features.Wix offers its users hundreds of website templates ââ¬â all of which are fully responsive ââ¬â and enables them to tinker with the editor to add their personal t ouches, so thats a good start.When it comes to the implementation of advanced features, Wix boasts a catalog of eighty appsà that can be added to your site in a matter of seconds. They range from form builders, to reservation systems, and even pricing tables.WordPress, on the other hand, only offers 15 official themes on its site. Thats pretty disheartening until you realize that there are thousands of third-party themes available on sites like ThemeForest, Elegant Themes, andà our very own ThemeIsle.Moving on, when it comes to plugins, WordPress is second to none. There are over 46,000 plugins available on WordPress.org, and the community shows no signs of slowing down. If you can imagine something, theres almost certainlyà a plugin for it.WordPress 1 : Wix 1 Round two of Wix vs WordPress goes to WordPress ââ¬â the undisputed king when it comes to customization options.3. SecurityWix and WordPress feature two entirely separate approaches when it comes to security. The fir st takes it entirely out of your hands ââ¬â aside from the basics such as choosing a good password and using two-factor authentication ââ¬â and handles the security aspect of things on their own. You sign up, you pay, and as long as the checks keep clearing, there will be people whose job it is to keep your site safe.WordPress, however, places the brunt of securing your website on your shoulders. You need to stay on top of core updates, check for various errors, choose the right host, and handle pretty much everything else yourself.To some people, this may sound like a lot of responsibility, but its mostly common sense. A WordPress website is as secure as its owner makes it.Furthermore, there are plenty of plugins dedicated solely to keeping your WordPress sites safe, such as WordFence. Wordfence Security Firewall Malware Scan Author(s): WordfenceCurrent Version: 7.4.0Last Updated: August 22, 2019wordfence.7.4.0.zip 96%Ratings 135,846,747Downloads WP 3.9+Requires W ordPress 2 : Wix 1 WordPress takes the crown again this round. Securing your WordPress site is not that challenging, and you should face no security problems as long as you stay on top of the factors we mentioned. Furthermore, you have the option to make your site as secure asà you want it to be.4. SupportWix offers both a robust knowledge base as well as telephone (you can request a callback) and support. The downside of Wixââ¬â¢s support is that they use templated messages quite a lot. So you may have to write them a few times to get your issue resolved if itââ¬â¢s a bit more complex. Response times are usually less than 24 hours, which is acceptable.On the other side of the coin, WordPress doesnt offer any specialized support aside from its knowledge base. However, entire libraries could be filled with the many articles that have been written on how to perform any imaginable action using the CMS.Whats more, most plugins and themes receive support from their developers, wh ich is kind of like always having aà chef available to answer your questions whenever youreà making a recipe.WordPress 3 : Wix 2 This round of Wix vs WordPress is a tie. Finding help for your particular issues may require a bit of googling with WordPress, but youll be sure to find an answer to just about anyà inquiry if you look hard enough.5. SEOWix hasnââ¬â¢t really got the best reputation for SEO. But rest assured, this comes mainly from Wixââ¬â¢s past when they were still a Flash-based website builder. In 2012 however, they switched to a completely new platform based on HTML5, adding all modern SEO options like customizable URLs as well as page titles and descriptions. They even added 301 redirects and the possibility to add canonical URLs to your pages. You can check this table for a full SEO feature list.An area they still need to work on is their loading speed. Despite having improved quite a bit already by adding advanced features such as page caching and better image compression, you are still limited to what the Wix editor allows you to do. Wordpress, on the other hand, letââ¬â¢s you do whatever you want. Not right out of the gate but if you install the right plugin(s) your SEO options will be limitless. Yoast is a great one but there are also very decent alternatives available.You also have much better options to crank up your loading speed by choosing your own host and adding plugins to cache and minify your pages.WordPress 4 : Wix 2 The final round goes to WordPress again. Even though Wixââ¬â¢s SEO options are probably more sufficient for beginners, if you are in a very competitive niche, itââ¬â¢s better to have to full arsenal of tools available.Wix vs WordPress: Which one should you use?Ultimately, we have to rule in favor on WordPress when it comes to the Wix vs WordPress debate. Heres why:It enables its users to customize every single aspect of their website.Despite forcing users to take security into their hands, it provi des them with all of the tools to do so.There are hundreds if not thousands of articles, tutorials, and videos available for tackling any issues you might encounter.Despite ruling for WordPress, we have to say that were mightily impressed by how easy it is to use Wix and the many options it provides. If youre just looking to get an attractive website up and running quickly, then it might just be the right pick for you.Choosing which platform youll use to develop your websiteà is a tough choice to make. Whichever decision you take will come with its own set of pros and cons ââ¬â but once youve taken that first step, the rest of your website designing career can begin at last!Ultimately, we decided to go with WordPress, but that is not to say that Wix isnt a viable option ââ¬â in fact, its a great tool for getting simple websites up and running fast, and it offers a lot of plans for different types of users.Which side are you on when it comes to the Wix vs WordPress debate?

Rumsfeld Differences essays
Powell/Rumsfeld Differences essays The rift in ideology and policy ideals between Secretary of State Colon Powell and Secretary of Defense Donald Rumsfeld had been catching the medias attention lately. In this paper, we will look at what these differenced are, what may be the cause of them, and with whom the President is siding with to formulate policy. It seems as of now, that the policy ideals of Secretary Rumsfeld are winning out over those of Secretary Powell partly because of the rekindled hard-line attitude of the American public following the events of September 11th. First, a brief background of the events on which this division of policy is based will be given in this paper, followed by Secretary Rumsfelds ideals and arguments, then those of Secretary Powell. We will then look at the policy decisions President Bush has made on this topic, and how the international community could perceive said policy. Let us look at the situation in Cuba and the decisions facing President Bush. Right now there are approximately three hundred detainees being held by United States forces at Camp X-Ray in Guantanamo Bay Naval Station, Cuba. Now, one might ask why these prisoners are being classified as detainees and not as prisoners of war. The United States is engaged in a self-proclaimed War on Terrorism, now being fought in Afghanistan. The foes being fought there are the forces of the Taliban regime and the Al Qaida terror network. Are these persons not combatants, are they not prisoners of a war? According to Secretary of Defense Donald Rumsfeld and his camp; no, they are not. Yet according to Secretary of State Colon Powell; yes, they are. The camp referred to as Donald Rumsfelds includes Vice President Dick Cheney and Deputy Secretary of Defense Paul Wolfowitz. They share the common view that the prisoners detained in Cuba, and in Afghanistan, are not Prisoners of War. According to the Geneva Convention, a pri...

Ground Sloths - A Survivor of the Megafaunal Extinction
Ground Sloths - A Survivor of the Megafaunal Extinction Giant ground sloth (Megatheriinae) is the common name for several species of large bodied mammals (megafauna) who evolved and lived exclusively on the American continents. The superorder Xenarthranswhich includes anteaters and armadillosemerged in Patagonia during the Oligocene (34-23 million years ago), then diversified and dispersed throughout South America. The first giant ground sloths appeared in South America at least as long ago as the late Miocene (Friasian, 23-5 mya), and by the Late Pliocene (Blancan, ca. 5.3-2.6 mya) arrived in North America. Most of the large forms died out during the late Pleistocene, although there is recently discovered evidence of ground sloth survival in central America as recently as 5,000 years ago. There are nine species (and up to 19 genera) of giant sloths known from four families: Megatheriidae (Megatheriinae); Mylodontidae (Mylodontinae and Scelidotheriinae), Nothrotheriidae, and Megalonychidae. Pre-Pleistocene remains are very sparse (except for Eremotheriaum eomigrans), but there are lots of fossils from the Pleistocene, especially Megatherium americanum in South America, and E. laurillardi in both South and North America. E. laurillardi was a large, intertropical species known as the Panamanian giant ground sloth, who may well have survived into the late Pleistocene. Life as a Ground Sloth Ground sloths were mostly herbivores. A study on over 500 preserved feces (coprolites) of the Shasta ground sloth (Nothrotheriops shastense) from Rampart Cave, Arizona (Hansen) indicate that they mainly dined on desert globemallow (Sphaeralcea ambigua) Nevada mormontea (Ephedra nevadensis) and saltbushes (Atriplex spp). A 2000 study (Hofreiter and colleagues) found that the diet of sloths living in and around Gypsum Cave in Nevada changed over time, from pine and mulberries around 28,000 cal BP, to capers and mustards at 20,000 years bp; and to saltbushes and other desert plants at 11,000 years bp, an indication of changing climate in the region. Ground sloths lived in a variety of ecosystem types, from treeless scrublands in Patagonia to wooded valleys in North Dakota, and it seems that they were fairly adaptive in their diets. Despite their adaptability, they almost certainly were killed off, as with other megafaunal extinctions, with the assistance of the first set of human colonists into the Americas. Ranking by Size Giant ground sloths are loosely categorized by size: small, medium and large. In some studies, the size of the various species seems to be continuous and overlapping, although some juvenile remains are definitely larger than the adult and subadult remains of the small group. Cartell and De Iuliis argue that the difference is size is evidence that some of the species were sexually dimorphic. Megatherium altiplanicum (small, femur length about 387.5 mm or 15 inches), and about 200 kilograms or 440 pounds per adult individuals) Megatherium sundti (medium, femur length about 530 mm, 20 in) Megatherium americanum (large, femur length between 570-780 mm, 22-31 in; and up to 3000 kg, 6600 lb per individual) All of the extinct continental genera were ground rather than arboreal, that is to say, lived outside of trees, although the only survivors are their small (4-8 kg, 8-16 lb) tree-dwelling descendants. Recent Survivals Most of the megafauna (mammals with bodies greater than 45 kg, or 100 lbs) in the Americas died out at the end of the Pleistocene after the retreat of the glaciers and about the time of the first human colonization of the Americas. However, evidence for ground sloth survival into the late Pleistocene has been found in a handful of archaeological sites, where research indicates that humans were preying on ground sloths. One of the very old sites thought by some scholars to be evidence of humans is the Chazumba II site in Oaxaca state, Mexico, dated between 23,000-27,000 calendar years BP [cal BP] (Vià ±as-Vallverdà º and colleagues). That site includes a possible cutmarkbutchery markon a giant sloth bone, as well as a few lithics such as retouched flakes, hammers, and anvils. Shasta ground sloth (Nothrotheriops shastense) dung has been found in several caves in the southwestern United States, dated to as late as 11,000-12,100 radiocarbon years before the present RCYBP. There are also similar survivals for other members of the Nothrotheriops species found in caves in Brazil, Argentina, and Chile; the youngest of those are 16,000-10,200 RCYBP. Solid Evidence for Human Consumption Evidence for human consumption of ground sloths exists at Campo Laborde, 9700-6750 RCYBP in the Talpaque Creek, Pampean region of Argentina (Messineo and Politis). This site includes an extensive bone bed, with over 100 individuals of M. americanum, and smaller numbers of glyptodons, panamanian hare (Dolichotis patagonum, vizcacha, peccary, fox, armadillo, bird, and camelid. Stone tools are relatively sparse at Campo Laborde, but they include a quartzite side-scraper and a bifacial projectile point, as well as flakes and micro-flakes. Several sloth bones have butchery marks, and the site is interpreted as a single event involving the butchery of a single giant ground sloth. In North Dakota in the central US, evidence shows that Megalonyx jeffersonii, Jeffersons ground sloth (first described by the U.S. President Thomas Jefferson and his physician friend Caspar Wistar in 1799), were still fairly widely distributed across the NA continent, from Old Crow Basin in Alaska to southern Mexico and from coast to coast, about 12,000 years RCYBP and just before most of the sloth extinction (Hoganson and McDonald). The most recent evidence for ground sloth survival is from the West Indian islands of Cuba and Hispaniola (Steadman and colleagues). Cueva Beruvides in Matanzas Province of Cuba held a humerus of the largest West Indies sloth, the Megalocnus rodens, dated between 7270 and 6010 cal BP; and the smaller form Parocnus brownii has been reported from the tar pit Las Breas de San Felipe in Cuba between 4,950-14,450 cal BP. Seven examples of Neocnus comes have been found in Haiti, dated between 5220-11,560 cal BP. Sources and Further Information Cartelle C, and De Iuliis G. 2006.
