Year upon year, it issues country-specific human rights reports, accusing more than 190 countries and regions, including China, of their human fights conditions. Yet it tums a blind eye to its own. It is just behind the "Statue of Liberty’" that hides serious infringements upon human rights.展开更多

Overall scores were compared across programs, and for subscales(autonomy, teaching, and social Support), using chi-squared, t-tests, and analysis of variance.RESULTS: A total of 219 surveys were returned for 260 residents across six programs(3 SA, 3 USA), with a response rate of 84%. Program-specific response rates varied from 79%–100%. All six residencies were qualitatively rated as "more positive than negative but room for improvement". Quantitative PHEEM scores for the USA programs were significantly higher: 118.7 compared to 109.9 for SA, P=0.001. In subscales, perceptions of social support were not different between the two countries(P=0.243); however, role autonomy(P<0.001) and teaching(P=0.005) were better in USA programs. There were no significant differences by post-graduate training year.CONCLUSION: EM residents in all three emergency medicine residency programs in SA and the three USA programs studied perceive their training as high quality in general, but with room for improvements. USA residency programs scored higher in overall quality. This was driven by more favorable perceptions of role autonomy and teaching. Understanding how residents perceive their programs may help drive targeted quality improvement efforts.展开更多

Current resources of...The current “mega” interest in Lithium resources was spurred by the development of Lithium-Ion batteries to aid in restructuring the world’s reliance on carbon spewing power petroleum reserves. Current resources of lithium recovery have fallen into two main categories—Pegmatite, found worldwide associated with felsic intrusions and Brine Related, and now with development in the Southwest United States of America (SWUS), a third category— Tertiary Volcanic clays, are specifically associated with Tertiary volcanics and major Tectonic Plate interactions. “Active” Plate tectonics is important as both the SWUS, the Lithium Triangle of South America (LTSA) and the Tibetan Plateau of China (TPC) producing tertiary (Miocene) volcanism that is important to the development of Lithium resources. The Tanzanian part of the East Africa Rift System (EARS) has features of both the SWUS, tertiary volcanic related “playas” and Continental rifting, the LTSA, tertiary volcanic related “Brines” and a major Tectonic plate event (subduction of an Oceanic Plate beneath the Continental South American Plate) and the TPC, tertiary volcanics (?) and major tectonic plate event (subduction of the Indian Continental Plate under the Eurasian Continental Plate). As well as the association of peralkaline and metaluminous felsic volcanics with Lithium playas of the SWUS and the EARS (Tanzania) “playas”. These similarities led to an analysis of a volcanic rock in Northeast Tanzania. When it returned 1.76% Lithium, a one-kilometer spaced soil sampling program returned, in consecutive samples over 0.20% Lithium (several samples over 1.0% lithium and a high of 2.24% lithium). It is proposed that these four regions with very similar past and present geologic characteristics, occur nowhere else in the world. That three of them have produced Lithium operations and two of them have identified resources of Lithium clay and “highly” anomalous Lithium clays should be regarded as more than “coincidental”.展开更多

Presently there are three educational paths that students may take to become a registered nurse （RN）. These are the baccalaureate degree （BS）, the associate degree （AD） and the diploma. Accelerated nursing programs are also available for people who have a baccalaureate degree in another field. Nursing education and nursing practice in the United States is regulated by each of the 50 states. The focus of nursing education is the preparation of nurses who use critical thinking skills to provide comprehensive patient-centered care to a variety of clients. It is expected that nurses will function using evidence-based practice in a culturally competent, safe manner. Nursing schools must be approved by the state in which they exist. In addition to this, most nursing schools are also accredited, a voluntary process that is done by a non-governmental association. All graduates take the same licensing exam, a computer adaptive test that is from 75 to 265 items long educated graduates were first time test takers; 85.5% passed the exam. Trends in nursing education In 2008 almost 120,000 US include a focus on evidence based practice, an emphasis on safety and quality, patient education and management of chronic conditions, genetics and genomics and the use of simulation in nursing education展开更多

Design/methodology/approach： Using relative values based on fractional counting, we investigate the distribution of publications across document types at both the journal and country level, and we use （cosine） document type profile similarity values to compare pairs of publication years within countries. Findings： Nature and Science mainly publish Editorial Material, Article, News Item and Letter, whereas the publications of PNAS are heavily concentrated on Article. The shares of Article for Nature and Science are decreasing slightly from 1999 to 2014, while the corresponding shares of Editorial Material are increasing. Most studied countries focus on Article and Letter in Nature, but on Letter in Science and PNAS. The document type profiles of some of the studied countries change to a relatively large extent over publication years. Research limitations： The main limitation of this research concerns the Web of Science classification of publications into document types. Since the analysis of the paper is based on document types of Web of Science, the classification in question is not free from errors, and the accuracy of the analysis might be affected.Practical implications： Results show that Nature and Science are quite diversified with regard to document types. In bibliometric assessments, where publications in Nature and Science play a role, other document types than Article and Review might therefore be taken into account. Originality/value： Results highlight the importance of other document types than Article and Review in Nature and Science. Large differences are also found when comparing the country document type profiles of the three journals with the corresponding profiles in all Web of Science journals.展开更多

It is also evidence that policy of the United States of America to make for its internal politics between two world wars was abandoned and it was intended to dominate world politics. Likewise, it can be considered as the smoking gun for power loss of continental Europe, including England, against the Soviet Union. When Turkey had to find its way into Western alliance in this new period divided into two poles and called as ＂Cold War＂, it intended to enter into economic acquis formed by Marshall Plan. Turkey, in the process to prevent the spread of communism against the Soviet Union that started mainly by Truman Doctrine, was of the first priority status by the USA just like Greece. It can be said that Turkish economy made an important progress to move into liberal system from its statist structure through Marshall Plan. Accession process to European Union integration mandated by the USA was started by Republican People＇s Party （CHP） and it was also continued in Democratic Party period with liberal program that took over the power as a result of elections in Turkey. Although Marshall Plan created economic added value in Turkey at the beginning, it could not create a sustainable welfare process as consultants coming from the USA had insisted on unilateral economic policies and Turkey was directed towards military spending due to being seen mainly as a buffer state against the Soviet Union and Middle East. It can be also said that arrangements arising from double standards in the application compared to European countries caused economic instabilities in the long run.展开更多

The axis now has been demonstrated to have implications for the treatment of several neuro-psychological illnesses, including Alzheimer’s Disease (AD), a condition that affects a person’s ability to connect socially and communicate effectively. Previously thought to be a rare disorder, it is now thought to affect 1 in 9 individuals in the United States. Unfortunately, there is not FDA-approved drug for the primary symptoms of AD, and the current cognitive-behavioral therapy procedures for the condition are time-consuming and expensive. Scientists are currently investigating the MGB axis to identify potential treatment targets to reduce AD symptoms. This review aims to highlight the functioning of the MGB axis;research into this dysfunction may effectively demonstrate the need of innovative AD treatment approaches, ranging from probiotics and dietary changes to more contemporary techniques like fecal transplants, vagal nerve stimulation, and gene therapy. Not simply behavioral intervention therapy, but also microbes, may hold the key to curing AD.展开更多
