Savvy college grads have really begun to see their Rosetta stone software
bridge year, the year after graduation but before work begins, as a great time to enhance the resume. If you can increase your fluency in a foreign language and gain some valuable work experience at the same time, you really cannot go wrong. When you start applying for jobs you really want to stand out from the crowd, and this kind of experience can give you the edge.Increasingly, people are seeing real benefit by attending Spanish schools in South America. If you are looking to learn Spanish quickly, you can definitely benefit from choosing to study Spanish abroad. Spanish schools in South America are an immersion experience and provide their students with a great deal of cultural exposure. These are world-class opportunities that you are unlikely to find elsewhere.Soon America will be home to more Spanish speakers than anywhere in the world other than Mexico. With the trend toward multilingual population, an ability to speak fluent Spanish will become increasingly important in the workplace. Additional benefits of spending one’s bridge year at Spanish schools in South America include networking opportunities. In today’s competitive job market any advantage can be a big advantage.There are organizations available that specialize in bridge year programs geared towards students looking to study Spanish abroad. Such programs include Rosetta Stone English
a 16 week adventure in Argentina, Chile, and Peru. Yet, it is not all studying and course work in Spanish schools in South America. These beautiful countries, of course, have a considerable amount to offer in culture rich activities and just good old-fashion fun. Tango dancing in Buenos Aires is only the tip of what you can do in this fast-paced cosmopolitan city. Likewise, Chile is loaded with natural wonders to explore and such fun activities as wine tasting, which will never get old.When you are choosing a Spanish school in South America be sure to find one that seeks to make sure that students have amazing travel experiences while they study Spanish abroad. As Jerry Wang of Texas expressed, "The social component of the trip is the best part of the whole experience. In 5 months, I've met about 200 people, ranging from 19-65 yrs old. There were students, pilots, dean's of universities, teachers, VPs of companies, small business owners, tons of lawyers, etc. from all over the world. The relationships I've built are lifelong and we continue to keep in touch.”Another important factor to look for in Spanish language schools in South America is whether or not internships are offered. The bridge year is the opportune time to boost the resume with an internship. Internships in South America can vary considerably. They can range from marketing internships to internships in social work to everything in between. You could find a six-month program where three months are spent learning Spanish and three months are spent working on an internship. Rosetta Stone America English Levev 1-5
Generally, programs begin in mid-June and end in mid-December. If you can gain an internship experience and Spanish fluency, your time abroad can provide lifelong dividends.While it is true that the internships don’t come with any pay, the upside is that the cost of living is very low in Peru, Argentina and Chile when compared to the cost of living in the United States. You will have no need for a car while other expenses such as housing, food and expenses such as nights out are a fraction of what they are in the States.Approaching your bridge year, as a time to increase your résumé’s “punch” is an idea that is garnering more and more attention from college graduates all the time. Spending a few months in exciting locations like Buenos Aires, for example, is definitely a reward that most college graduates (even those who already partied a little too much) will feel that they have earned. Whether you are wine tasting or snowboarding in Chile or enjoying big-city life in an amazing city like Buenos Aires, studying Spanish abroad can likely be an experience that you will never forget. And all the while you can be putting in those graduate school applications and even applying for jobs while you are in South America. The fact that your application is arriving from out of the country, as you study at one of the Spanish schools in South America, is enough on its own to make your application stand out to potential employers or graduate school admission officers.

The Big Squeeze
First, community colleges are no longer offering Rosetta stone
as much practical training as they once did. To attract more students, many have modified their course offerings to become more like private institutions. While President Obama has pledged to invest heavily in community colleges and upgrade their training programs, the changes are long overdue. Second, for-profit colleges and universities are in trouble. A number of them are being investigated right now by Congress because of shady recruiting practices and abuse of government programs for funding higher education. It seems likely that a number of for-profit schools will shut their doors.The result? American students will find it harder to find schools that offer the practical training they need to secure jobs. And we all know what can happen when a country's workers are under-trained, compared to workers in other countries. The result will likely be further damage to the American economy and business.What Rosetta Stone Spanish
Will Save American Higher Education?The trends outlined above are grim. Yet the situation is far from hopeless. A number of positive trends are at work that point to the possibility that American higher education is not going away, but simply changing.*America still has the strongest educational infrastructure in the world. We simply have more colleges and universities than any other country. Many of these institutions are already reinventing themselves by offering distance learning options, three-year degree programs and other incentives for modern learners. *Americans' desire for education remains strong. With so many of our citizens hungering for learning, there is ample incentive for colleges to develop new learning options for them. *The timeline of education has changed. More Americans are returning to college at all stages of life. The result is that a larger pool of Americans who are interested in higher education. Rosetta Stone Spanish (Latin America) Levev 1-5
*Distance learning is moving into the forefront of American higher education. As Bill Gates predicted on August 9 in his talk at the Techonomy conference in Lake Tahoe, it is already possible to deliver a college education over the Internet for as little as $2,000. In the end, we predict that American ingenuity will not only survive these crises, but turn America into a new kind of community of learners.

They found that reporting was very inconsistent.Muscle rosetta stone version 3
s trength, the most commonly reported outcome, was discussed in 84 percent of articles. Range of motion, however, was reported in less than half of the papers. No papers measured motion of the entire upper extremity and only 14 percent of papers detailed how the motion was measured. Functional outcome scores were recorded in only 12 percent and scores were recorded using different tools, so comparing studies was difficult. Functional outcome scores were recorded using a variety of different tools, including the DASH (Disabilities of the Arm, Shoulder, and Hand measure), a 30-item, self-report questionnaire designed to measure physical function and symptoms, as well as other tools such as the Constant Score for Shoulder Function, VAS functional score, or institution-specific questionnaires. Only 27 percent of papers measured sensation and only 8 percent recorded assessments of pain. No article reported all five outcome measurements: strength, range of motion, functional scores, sensibility, and pain. The maximum number of outcomes a paper reported was three (14 percent of papers), and the remaining articles reported only one or two outcomes.In a second study, the same investigators describe a first draft of a tool that they hope clinicians can use so that the reporting of outcomes is standardized. What we are doing is presenting this to the international community to get buy in on the concept, said Scott W. Wolfe, M.D., hand and upper extremity surgeon and director of the soon-to-open Hospital for Special Surgery Center for Rosetta Stone Japanese
Brachial Plexus and Complex Nerve Injury. This is a first iteration and we hope the group will respond favorably, but we'd like to get researchers and plexus surgeons from the Far East, Europe, the States and South America to work together to design a system that we all feel will function effectively for our patients.Dr. Wolfe said they had looked at different tools that doctors were using to see if they could come up with one that would work for brachial plexus surgery, but none of them were adequate and inclusive. We had to take elements of different instruments as well as elements that we designed to derive a complete system, Dr. Wolfe said. We're studying an injury of several critical nerves, an injury that affects the arm in a way that is very different from that of a fracture or degenerative disease. We needed to design an innovative way to analyze and report outcomes, because we're simultaneously assessing nerve, muscle and joint recovery. By way of example, although a patient's nerves could recover beautifully in a particular case, if their shoulder is frozen or their hand atrophied, the patient may not have a functional recovery; unless all elements are assessed, the analysis is incomplete.The key elements of the instrument are measurements of motion, strength and function for seven critical domains of the upper extremity: shoulder elevation, Rosetta Stone Spain Spanish
shoulder external rotation, elbow flexion, elbow extension, wrist extension, finger flexion and intrinsics (the distance the fingers can be spread apart). The tool involves assessing tasks such as touching the back of your head, touching your mouth and holding a utensil.The researchers hope that with help from the international community, the tool can be refined and outcomes can be standardized across research centers and across continents.Rohit Garg, M.D., at Hospital for Special Surgery, was also involved with the study.

Sleep Helps People Learn Complicated Tasks
Using a test that involved learning to play rosetta stone version 3
video games, researchers showed for the first time that people who had forgotten how to perform a complex task 12 hours after training found that those abilities were restored after a night's sleep.Sleep consolidated learning by restoring what was lost over the course of a day following training and by protecting what was learned against subsequent loss, said Howard Nusbaum, Professor of Psychology at the University of Chicago, and a researcher in the study. These findings suggest that sleep has an important role in learning generalized skills in stabilizing and protecting memory.The results demonstrate that this consolidation may help in learning language processes such as reading and writing as well as eye-hand skills such as tennis, he said.For the study, researchers tested about 200 college students, most of whom were women, who had little previous experience playing video games. The team reported the findings in the paper, Consolidation of Sensorimotor Learning During Sleep, in the current issue of Learning and Memory. Joining Nusbaum in the research were lead author Timothy Brawn, a graduate Rosetta Stone French
student in Psychology at the University; Kimberly Fenn, now an Assistant Professor of Psychology at Michigan State University; and Daniel Margoliash, Professor in the Departments of Organismal Biology Anatomy and Psychology at the University.The team had students learn video games containing a rich, multisensory virtual environment in which players must use both hands to deal with continually changing visual and auditory signals. The first-person navigation games require learning maps of different environments.For the study, researchers used first-person shooter games, with the goal of killing enemy bots (software avatars that play against the participant) while avoiding being killed.The subjects were given a pre-test to determine their initial performance level on the games. Then they were trained to play the games and later tested on their performance. One group was trained in the morning and then tested 12 hours later after being awake for that time. A second group was trained in the morning and then tested the next day, 24 hours after being trained. Another group was trained in the evening, then tested 12 hours after a night's sleep and a fourth group was trained in the evening and then also tested 24 hours after training.When trained in the morning subjects showed an 8 percentage point improvement in accuracy Rosetta Stone French Levev 1-5
immediately after training. However after 12 waking hours following training, subjects lost half of that improvement when tested in the evening. When subjects were tested the next morning 24 hours after training, they showed a 10 percentage point improvement over their pre-test performance.The students probably tested more poorly in the afternoon because following training, some of their waking experiences interfered with training. Those distractions went away when they slept and the brain was able to do its work, Nusbaum said.Among the students who received evening training, scores improved by about 7 percentage points, and went to 10 percentage points the next morning and remained at that level throughout the day.The study follows Fenn, Nusbaum and Margoliash's earlier work, published in Nature, which showed for the first time that sleep consolidates perceptual learning of synthetic speech.In that study we showed that if after learning, by the end of the day, people 'forgot' some of what was learned, a night's sleep restored this memory loss, Nusbaum said. Furthermore a night's sleep protected memory against loss over the course of the next day.The latest study expanded that work to show that sleep benefits people learning complicated tasks as well, Nusbaum said.

New approach helps teachers integrate conservation biology into high school ecology classes
The authors of the study tested this ecology rosetta stone version 3
-disrupted framework using two case studies in the classrooms of more than 30 teachers in New York City public schools in 2008 and 2009. They found that students in all cases developed a better understanding of ecological concepts such as abiotic and biotic factors and habitat, as well as a better understanding of how their daily life can affect the natural world.We hope our model will be used to encourage students to understand the complexity of ecological processes and the role of human behavior in disrupting ecosystems, said Wyner, the study's first author. This may lead students to be more environmentally aware and perhaps be more environmentally responsible.Many conservation biology research Rosetta Stone Japanese
studies can easily be rephrased as questions that link daily life to the particular environmental issues described in the studies, said DeSalle. For example, a report on land use and climate change can be explored in the classroom as 'how does having a big backyard harm native wildlife?' In the two case studies used in the research, the authors used real data from published studies and Science Bulletin video presentations developed at the American Museum of Natural History. One study examined how highways bisecting the Sierra-Nevada Mountains are blocking the movements of bighorn sheep and leading to inbreeding, while the other study explored how salt added to roadways to melt snow was causing freshwater streams to become progressively saltier. The Science Bulletins, which are produced by the National Center for Science Literacy, Education, and Technology, a part of the Department of Education at AMNH, were screened to present students with other examples of people disrupting abiotic factors in unexpected ways.The authors intend to modify and retest their teaching modules by introducing their ecology-disrupted Rosetta Stone Spain Spanish
case study model into the classrooms of 60 teachers for the 2010-2011 school year. After testing, the modules will be available for dissemination on the Museum's education website.This research was funded in part by the National Science Foundation.

Athapaskan Migration To Southwest U.S. Illuminated With Y Chromosome Study
The study, led by researchers at the University of Illinois,
is detailed this month in the American Journal of Rosetta stone
Physical Anthropology. It relied on a genetic analysis of the Y chromosome and so offers a window on the unique ancestral history of the male Athapaskan migrants. Previous genetic studies of this group focused on mitochondrial DNA, which is passed down exclusively from mothers to their offspring.The new findings reinforce the hypothesis that the Athapaskan migration involved a relatively small group that nonetheless was very successful at assimilating and intermixing with native groups already living in the southwest. The newcomers were so influential that the Athapaskan language family now dominates many parts of the Southwest. Now called Apacheans, the Navajo and Apache descendants of the early migrants are dispersed throughout the central Southwest and speak languages closely related to the Chipewyan, an Athapaskan language found in the subarctic.(Language studies also revealed that Athapaskans migrated to the northwest U.S. and settled on the coast in parts of California and Oregon.)How the Athapaskan migrants were able to spread their language -- and genes -- so successfully is unknown. Anthropologists note that the migrants probably arrived in the Southwest at a time of stress among indigenous groups as a result of an extended drought.The new study also revealed how pervasively European males intermixed with native groups, said principal investigator Ripan Malhi, a molecular anthropologist in the department of anthropology at Illinois.A lot of the Y chromosomes have been replaced by European males, he said.Malhi Rosetta Stone Spanish
and his colleagues looked at specific regions on the Y chromosome that can vary from person to person. Tiny differences in the sequence of nucleotides that spell out the genetic code can be used to determine whether -- and how closely -- individuals are related to
one another. Those who share many of these genetic signatures are more likely to share a recent common ancestor than those who don't.The researchers analyzed 724 Y chromosomes from 26 native populations in North America. By including groups from across the continent (they studied tribes from Alaska to the Yucatan Peninsula and eastward to Hudson Bay and southeast U.S.), the researchers were able to analyze genetic differences among many native groups and to get an idea of the degree of European male infiltration into the native gene pool.Consistent with a previous study of native North American mitochondrial DNA (also led by Malhi), the new analysis found a pattern that indicates that a small group of subarctic Athapaskans miYgrated to the Southwest. This pattern is reflected in the fact that many Apacheans carry the genetic signature of a small subset of subarctic Athapaskans.These findings also affirm an earlier study of variants of a particular protein, albumin, in different native groups. That study showed that while many Apacheans carried an albumin variant common among natives in the Southwest and Mesoamerica, some Apacheans were the only ones to carry a variant that also occurs in subarctic populations.Other patterns emerged from the Y chromosome analysis. One genetic signature associated with European
Rosetta Stone Spanish (Latin America) Levev 1-5
males was detected in native males throughout North
America, but was found at the highest frequency in groups living nearest to Hudson Bay, where trade between Europeans and the region's indigenous peoples was established in the early 17th century.The new study, along with the earlier genetic and protein studies and the language analyses, is filling a gap in the archaeological record of Athapaskan migration, Malhi said.This gap is the result of the fact that the Athapaskan migrants seem not to have altered the physical landscape, architecture or cultural practices of the populations they assimilated in the southwest U.S.The only lasting evidence of the Athapaskan migration found so far is in their language and their genes, Malhi said.We're fitting together different lines of evidence, he said. We're not just using the genetic data. We're using it in combination with the linguistic, oral histories from elders in the community and archaeological data. And even though there has been over a century of archaeological research done in the Southwest,
there's not much information there about the Athapaskan migration into the Southwest.The team also included researchers from the Universidad Nacional Autonoma de Mexico, the University of California at Davis, Washington State University, the University of Montana, the University of Arizona and Trace Genetics.

The newcomers were so influential that the Athapaskan language family now dominates many parts of the Southwest. Now called Apacheans, the Navajo and Apache descendants of the early migrants are dispersed throughout the central Southwest and speak languages closely related to the Chipewyan, an Athapaskan language found in the subarctic.(Language studies also revealed that Athapaskans migrated to the northwest U.S. and settled on the coast in parts of California and Oregon.)How the Athapaskan migrants were able to spread their language -- and genes -- so successfully is unknown. Anthropologists note that the migrants probably arrived in the Southwest at a time of stress among indigenous groups as a result of an extended drought.The new study also revealed how pervasively European males intermixed with native groups, said principal investigator Ripan Malhi, a molecular anthropologist in the department of anthropology at Illinois.A lot of the Y chromosomes have been replaced by European males, he said.Malhi Rosetta Stone Spanish
and his colleagues looked at specific regions on the Y chromosome that can vary from person to person. Tiny differences in the sequence of nucleotides that spell out the genetic code can be used to determine whether -- and how closely -- individuals are related to
one another. Those who share many of these genetic signatures are more likely to share a recent common ancestor than those who don't.The researchers analyzed 724 Y chromosomes from 26 native populations in North America. By including groups from across the continent (they studied tribes from Alaska to the Yucatan Peninsula and eastward to Hudson Bay and southeast U.S.), the researchers were able to analyze genetic differences among many native groups and to get an idea of the degree of European male infiltration into the native gene pool.Consistent with a previous study of native North American mitochondrial DNA (also led by Malhi), the new analysis found a pattern that indicates that a small group of subarctic Athapaskans miYgrated to the Southwest. This pattern is reflected in the fact that many Apacheans carry the genetic signature of a small subset of subarctic Athapaskans.These findings also affirm an earlier study of variants of a particular protein, albumin, in different native groups. That study showed that while many Apacheans carried an albumin variant common among natives in the Southwest and Mesoamerica, some Apacheans were the only ones to carry a variant that also occurs in subarctic populations.Other patterns emerged from the Y chromosome analysis. One genetic signature associated with European

males was detected in native males throughout North
America, but was found at the highest frequency in groups living nearest to Hudson Bay, where trade between Europeans and the region's indigenous peoples was established in the early 17th century.The new study, along with the earlier genetic and protein studies and the language analyses, is filling a gap in the archaeological record of Athapaskan migration, Malhi said.This gap is the result of the fact that the Athapaskan migrants seem not to have altered the physical landscape, architecture or cultural practices of the populations they assimilated in the southwest U.S.The only lasting evidence of the Athapaskan migration found so far is in their language and their genes, Malhi said.We're fitting together different lines of evidence, he said. We're not just using the genetic data. We're using it in combination with the linguistic, oral histories from elders in the community and archaeological data. And even though there has been over a century of archaeological research done in the Southwest,
there's not much information there about the Athapaskan migration into the Southwest.The team also included researchers from the Universidad Nacional Autonoma de Mexico, the University of California at Davis, Washington State University, the University of Montana, the University of Arizona and Trace Genetics.
