Overview of Thylacosmilus

Name: Thylacosmilus (Greek for pouched sabre); pronounced THIGH-lah-coe-SMILE-us Habitat: Woodlands of South America Historical Epoch: Miocene-Pliocene (10 million to 2 million years ago) Size and Weight: About six feet long and 500 pounds Diet: Meat Distinguishing Characteristics: Short legs; large, pointed canines About Thylacosmilus The saber-toothed mammal plan has been favored by evolution more than once: Killer fangs didnt develop only in the large placental mammals of the Miocene and Pliocene epochs, but in prehistoric marsupials as well. Exhibit A is the South American Thylacosmilus, the huge canines of which apparently kept growing throughout its life and were kept tucked in pouches of skin on its lower jaw. Like modern kangaroos, Thylacosmilus raised its young in pouches, and its parental skills may have been more developed than those of its saber-toothed relatives to the north. This genus went extinct when South America was colonized by the true mammalian saber-toothed cats, exemplified by Smilodon, starting about two million years ago. (A recent study has found that Thylacosmilus possessed an embarrassingly weak bite for its size, chomping down on its prey with the force of an average house cat!) By this point, you may be wondering: how is it that the marsupial Thylacosmilus lived in South America rather than Australia, where the vast majority of all modern marsupials reside? The fact is, marsupials evolved tens of millions of years ago in Asia (one of the earliest known genera being Sinodelphys), and spread to various continents, including South America, before making Australia their favored habitat. In fact, Australia had its own version of a large, catlike carnivore, the similar-sounding Thylacoleo, which was only distantly related to the line of pseudo-saber-toothed cats occupied by Thylacosmilus.

Digital Divide free essay sample

The term digital divide emerged in the mid-1990’s to describe the gap that exists between individuals who have access to technology and those that do not have access (Eamon, 2004). Computer technology has transformed modern society in profound ways (Behrman Shields, 2000). Everyday society exposes citizens to technology in some form. Citizens integrate technology into common tasks such as signing into work, paying bills, shopping, paying taxes, and even reading the local newspaper (Behrman Shields, 2000). The increasing integration of technology into society cause school systems to be more resolute about including technology in every classroom. School leaders generally agree that access to technology prepares students to succeed in the 21st century (Bell, Judge, Puckett, 2006). Other researchers point out that increasing access to technology in the classroom environment does not ensure academic improvement. These researchers point out that there are limits to the advantages that technology offers. A meta-analysis by Crismann, Badgert and Lucking (1997) involving 27 studies concerning academic achievement of students who received traditional classroom instruction or traditional classroom instruction with technology integration showed interesting results. The new presidential administration did not have as great an interest in digital access and eventually â€Å"Digital Divide† became â€Å"Digital Inclusion. † The NTIA was eventually downgraded and its budget taken away. These actions eventually and effectively ended the NTIA The question of it the Digital Divide is real can be answered by looking at the numbers, A report done by the Pew Research Center shows that one in five American adults does not use the internet, with senior citizens, those with less than a high school education and lower income adults being the least likely to have access to the internet. (Smith, Zickuhr, 2012) Americans with disabilities are even less likely to use the internet. Nearly half of those that do not go online say that don’t because they do not feel the internet is relevant to them. One thing that is helping to bridge the digital divide is the ever changing face of mobile technology. With the face of mobile technology changing at a rapid pace, those that were on the other side of the digital divide are now able to go online. Out of those groups, young adults, minorities, those with no college experience and lower income adults are more likely to use their smart phone as a main source of internet access. Internet use has grown greatly among U. S adults. In a span of 16 year, June 1995 to Jan 2011, internet use among those 18 and over has gone from just 14% to 78%. Smith, Zickuhr, 2012) In these numbers the line is still senior citizens, minorities, and low income as those less likely to have online access. A majority of those that do not use the internet feel they do not need it or are cautious of new technology. The difference between 2000 and 2011 is significant. In June of 2000 only 50% of American adults used the internet. That number jumped to 80% in 2011. ( Smith, Zickuhr, 2011) A household’s income plays a factor in internet use as well. In August 20111 only 62% of households with income less that $30,000 use the internet. When you compare these numbers to those making over $75,000 that have an internet usage of 97%, the Digital Divide is evident. The gap between whites and minorities is quickly disappearing. There are still some differences in internet access but they have become less noticeable and in some cases have disappeared all together. The strongest negative predictors for internet use are not race or gender, instead those factors now include seniors (those age 65 and older), low income (under $20,000), and lack of a high school education. Among these groups there have been some increases in internet use, but there is still a gray area for some such as seniors. Even though those 65 and over are less likely to use the internet, 41% now do go online. (Smith, Zickhur, 2012) The reasons that adults do not use the internet vary. In the year 2000, 54% of American adults felt that the internet was a dangerous thing. This feeling was especially true among seniors and individuals with less than a high school education. Research also show that 39% that that access to the internet cost to much and 36% found the internet confusing and difficult to se. (Smith, Zickuhr, 2012) More recent research shows the biggest reason of not going online is the do not feel the internet is relevant to them. 48% do not want to use it or feel that do not need it to get the information they need. A majority of non-users have never use the internet before and have no one in the household that does know how to use it. Only a very small percentage one i n ten, are interested in using it in the future. One thing that is changing the Digital Divide is mobile technology as mentioned above. Currently 88% of Americans age 18 and over have a cell phone. With mobile technology expanding, 63% of American adults use a mobile device- Laptop, tablet computer, e-book reader, cell phone- to go online. The rise in mobile devices has caused a noticeable mobile difference. (Smith, Zickuhr, 2012) A person becomes more active using the internet once they get a mobile device. Of the mobile devices, smartphones are becoming more widely used than basic cell phones. Among American adults 46% now has a smartphone. (Smith, Zickuhr, 2012) There are groups that have greater levels of smartphone use such as higher income, well educated and those under age 50. These groups also have higher rates of technology use. Younger adults (under age 30) do have a higher than average level of smartphone use no matter their income or education. Those younger adults with only a high school education or less are actually more likely to own a smartphone than older adults (age 50 and over) who have gone to college. The same holds true for income, young adults in the lower income bracket (under $30,000) are more likely to have a smartphone than older adults in the higher income bracket. Among these users, 25% say they use their smartphone as their main source of internet access. Smartphones are helping to bridge the Digital Divide. Computer sales during the holidays fell for the first time in 5 years as gadget use such as smartphones grows. According to Walker Sands a digital marketing agency, 23% of total global website visits came from mobile devices which is up from 17% in the 3rd quarter. (Leonard, 2013 These numbers show how big the shift is to how people connect. Former President Bill Clinton said in a key note speech at the Consumer Electronics Show â€Å"Mobile Technology is doing so much now to lift the poor. Smartphones are a much cheaper way for internet access and the capabilities that go along with it such as mobile banking and social media. The smartphone is a unique item when it comes to personal technology and the Digital Divide. At the same time it represents the cutting edge of technology. It is of course the choice for people of any economic class as the most economical and efficient way to connect in an age where getting on the internet ranks up there as a top priority right below food, shelter and water. The Digital Divide will most likely always be there but with modern mobile technology it appears to be shrinking. It does affect people not only here in the United States but also people across the globe. If you look at recent technology and the future, the implications are without a doubt very fascinating. What would happen if everyone had an affordable computer in their pocket or purse? What about the balance or more correctly imbalance of political power? All of this seems uncertain but the possibilities are endless. One thing that is certain, the Digital Divide will always exist. There will always be those that just cannot afford it in any form. There will always be that that just do not find the internet relevant in their lives. There will also be those that want to use the internet but don’t know how. The question that remains is â€Å"How much can we bridge the Digital Divide? † That question may never be fully answered. References Arnold , B. (2007 , Feb). Caslon analytics digital divides.
