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

The absorption to aN was best to perennial ryegrass while nN to barley. According to the differential analysis of N content, treatments of both aN and nN was nitrogen superfluous, which led to release excessive N to the atmosphere, and the rainwater treatment and the control were N deficient, the largest N absorption from atmosphere was 0.698 g in rainwater treatment.[Conclusion] Average N use efficiency contributed by atmosphere N deposition ranged from 1.321%-6.116%, while the control of barley had the highest of 6.116%.展开更多

A hands-on practical was developed to simplify detection of enzyme activity of amylase, protease and lipase on starch agar, dry whole milk agar, and trihutyrin agar, respectively. The subjects of the study were 24 senior undergraduates who studied in the Program of General Science, Faculty of Science, Srinakharinwirot University, Bangkok, in three semesters during 2007 - 2008. The basic concepts of enzymes, e.g., substrate specificity, how to detect enzymes and optimal enzyme conditions, were taught before the practical. The first enzyme, protease, was used in the second semester of 2007, and then changed to be lipase and protease in the first and second semesters of 2008, respectively. Ten open-ended questions were used to assess students in all semesters. In agreement with the constructivist learning model, it was demonstrated that students had learning retention and applied their prior knowledge to other enzyme experiments.展开更多

Methods and Materials： A randomly sampled population of 280 students and 12 managerial staff of sport and medical units participated in the descriptive study. Responses to a validated questionnaire provided the source of data. A test-retest reliability coefficient （r） = 0.80. Data were analyzed with simple percentages and Chi-square at 〈 0.05 alpha level. Results： All the respondents in medical centre and sport unit oriented the students on the available medical services and facilities on campus： availability of first aid services, treatment services for complicated injuries （inpatient）, referral services for specialized care, financial support during hospitalization. Complementary results from the students showed that the majority of the respondents （50%） strongly agreed that medical centre was available in the Campus, and 36% strongly affirmed to availability of first aid services. Thirty four percent of the respondents strongly agreed to the availability of treatment services, while 40% of the respondent agreed to the availability of free medical services. The study revealed that there was a significant relationship between efficient medical services and students＇ participation in sports. Conclusion： All medical services were available but students perceive the services as inefficient which implies poor or non utilization.展开更多

Sample included 67 first year university undergraduates. All the 67 students considered prior knowledge of the high school five-paragraph essay writing style helpful. They believed that it facilitated a transfer of learning in the first-year university undergraduate academic writing course. However, only 15 out of the respondents, who reported that prior knowledge of the high school English language five-paragraph essay writing style was helpful, also reported that they are level-appropriate competent in the first-year university undergraduate English language academic writing courses after one academic year. As such, essay-writing in high school offers students some foundation-knowledge to succeed in academic writing in universities. Further findings showed that students often delve into essay or academic writing without proper planning. Thus, it is recommended that universities introduce a bridge course specifically to address academic deficiency in reading and writing for all first year undergraduates upon admission into the university.展开更多

According to the criteria in EUCT （Evaluation in Undergraduate Course Teaching）, college libraries should meet certain standards and the cost will be large. Given the current condition that governmental funding is inadequate, we have to control the cost by ourselves. Our solutions to cost control will focus on three aspects： manpower of stuffs, hardware of library and the maintenance of library.展开更多

This approach is expected to foster the students＇ design skills in design studios. The approach is an educational tool for tutors that could guide the students and increase their creativity in their design. It considers the concepts and the practice of digital architectural design that influence architectural education. The approach is a catalyst for creativity, experimentation, critical thinking and the sustained growth of creative communities. The core of design studio is the notions, methods and skills of digital architectural design. The instruments used for this research was an investigation that made for the work of the fourth year students designs at the architectural department at University of Jordan, by testing design process and product of students＇ work： first using manual skills, and then using computer-aided programs. The results revealed that the computer-based design approach was able to foster students＇ design skills as well as to develop their creativity in design. Ninety-one percent of 44 students were found improved in design process using computer-based approach that depends on computer programs. This was done in design studio by improving students＇ way of thinking, developing their abilities to direct their own learning and pushing them for new definitions in developing their future work.展开更多

In his famous lecture, he told us that the most powerful revolutionary force in the world today is science, science is essentially progressive, and the scientific culture is also a newer one. So Snow, after excluding scientific culture from the whole culture, calls the rest of the whole culture traditional culture. In his opinion, science is more important than humanities. All these ideas are faithfully reflected in his earlier literary work The Masters （1972b）. Snow＇s favor toward men of sciences in the novel is self-evident. ＂The Masters, therefore, may be considered as a political science novel rather than as a political novel＂. It was the Industrial Revolution which created our sensibility展开更多

But in the after development, psychology met the unprecedented contradiction and conflict, facing division and broken, and in the embrassmed situation of divorced from society, positive psychology is emerge as the times requirement in this crisis. In order to better guide the development to positive psychology, providing philosophical theory and instructions on methodology,it is neeessary to discuss about the positive psycholog from a philosophical perspective. Since 1879 the western modern psychology come into being, the psychology of natural science orientation has been the mainstream of psychology. In addition, admit the uniqueness of man, attention to people＇s inner experience of humanistic psychology, also occupies a space in the confrontation with the reflection of the mainstream of scientific psychology, positive psychology from the research content to lead psychology to another port, but the research methods are not completely abandon the previous research methods of positivism psychology, but more introduced humanism based on the oositivism research method of scientific oriented.展开更多

Undergraduate students are supposed to get the possibility to design and build up a real train which serves as demonstrator for a mechatronic system. This project strengthens the motivation of students, since a practical demonstration of electromagnetic forces is given in addition to theoretical courses. This paper introduces the major project steps and explains the learning targets for the students. It focuses on analytical magnetic circuit design, numerical field simulation, modeling and control of a multi degree of freedom system, electronic circuit design, measurement setups and a first prototype test bench.展开更多

It is easy to pick up several parts of their representative works and prove that this thesis is corresponded to the original of Plato and Aristotle. But, in reflections of philosophy, we should not ignore a cautious view, focused just on this starting point： If the above mentioned thesis is used like a slogan, ＂Plato for idealism, Aristotle for realism,＂ as it often is, in the meantime there arises a dogmatic position which fixes our mental and intellectual activity only within the frame, so that everyone begins to reflect on Plato or Aristotle from that starting point in a certain framework. A critical and self-critical view of philosophy may bring this position for a query.展开更多

Patents are part of research and knowledge production. The scientific community and policy makers are increasingly interested in production of knowledge collaboratively. Almost all of the research being conducted on snow avalanches uses technology, technique or instrumentation. One main objective of this study is to draw from the literature the many technologies, techniques and instrumentations that are being used in research related to avalanches. Thus, a textual analysis of the most significant literature in the field of snow avalanches was done. In this analysis, techniques, technologies and instrumentations have emerged. A patent search has been done in databases. Subsequently, patents were conceptualized. The proportion of applicants for patents is higher in industry than in universities. The measure of exploration of the ongoing sociocognitive transformations of science and technology systems presents a useful tool to conduct a study to explore these transformations. It would be interesting for the scientific community, but also for the industry, to elaborate concept mapping when applied to avalanche research, which would help in determining referents.展开更多
