屈原生辰研究综述

屈原是中国历史上第一个伟大诗人,他创作的楚辞体文学开创了中国文学的另一个源头。由于朝代邈远,战乱频仍,使很多关于屈原的珍贵史料荡然无存,因此,对这样一位重要的作家,关于其生平的材料却只有一鳞半爪,使后世的研究者对其人其作争论不休,至今未有定论。关于其生辰的争论一直是个焦点,自王逸,朱熹各自提出关于屈原出生日期的观点以来,关于屈原生辰的研究便没有停止过,特别是近代,更是对屈原的生辰进行前所未有的实证性研究。本文尽量穷尽关于屈原生辰的研究成果,以期能给后来研究者提供这一论题的研究全貌。

How to Teach by the Unit Method

Using data from the National Center for Educational Statistics research spanning fifteen years, researchers examined the impact of national educational policy implementation on the role of social studies in elementary schools. Specifically, with the reauthorization of No Child Left Behind (NCLB) in 2007 and the continuation of federal-mandated testing of English language arts (ELA) and mathematics in grades three through five, researchers sought to understand how policy decisions to extend testing to science affected teacher decisions in regard to instructional time allocations for core subject areas of ELA, mathematics, science, and social studies in elementary schools. Results of this quantitative study offer large-scale evidence of the declining role of social studies in an era in which testing is clearly linked to subject-area importance. Findings provide an overview of the national scope of testing and the ramifications for social studies in elementary schools. Researchers conclude that curriculum standardization, accountability, and high-stakes testing have had adverse affects on social studies time allotments in comparison to tested subjects.     

Quantitative Risk Assessment of the New York State Operated West Valley Radioactive Waste Disposal Area

This article is based on a quantitative risk assessment (QRA) that was performed on a radioactive waste disposal area within the Western New York Nuclear Service Center in western New York State. The QRA results were instrumental in the decision by the New York State Energy Research and Development Authority to support a strategy of in‐place management of the disposal area for another decade. The QRA methodology adopted for this first of a kind application was a scenario‐based approach in the framework of the triplet definition of risk (scenarios, likelihoods, consequences). The measure of risk is the frequency of occurrence of different levels of radiation dose to humans at prescribed locations. The risk from each scenario is determined by (1) the frequency of disruptive events or natural processes that cause a release of radioactive materials from the disposal area; (2) the physical form, quantity, and radionuclide content of the material that is released during each scenario; (3) distribution, dilution, and deposition of the released materials throughout the environment surrounding the disposal area; and (4) public exposure to the distributed material and the accumulated radiation dose from that exposure. The risks of the individual scenarios are assembled into a representation of the risk from the disposal area. In addition to quantifying the total risk to the public, the analysis ranks the importance of each contributing scenario, which facilitates taking corrective actions and implementing effective risk management. Perhaps most importantly, quantification of the uncertainties is an intrinsic part of the risk results. This approach to safety analysis has demonstrated many advantages of applying QRA principles to assessing the risk of facilities involving hazardous materials.     

The effects of correlation among observations on the consistency property of sample variance

It is well known that even when the sample observations are correlated and not normal the sample variance, S² converges in probability to E(S²). But the required sample size for S² to be a consistent estimator of E(S²) is an open question. Some light is shed on this question in this paper. In particular the relation between the rate of convergence and the correlation property of the observations is explored. It is shown that the retardation to the rate of convergence is not appreciable if the correlation is moderate but it can be severe for extreme correlations.

The Special Historical Section of the Journal of American College Health

Abstract

Objective: To identify human papillomavirus (HPV) infection and HPV vaccine–related attitudes among college-aged women and the relationship between HPV vaccine uptake and subsequent sexual behaviors. Methods: PubMed, MEDLINE, CINAHL, and Google Scholar searches were performed from 2006, the date after the first HPV vaccine became available, to present. Results: Of the 13 studies identified, most were cross-sectional. College-aged women saw HPV infection as serious and had positive attitudes toward the HPV vaccine. Barriers (ie, cost, lack of insurance coverage) existed that prevented women from obtaining the vaccine and many women did not see themselves at risk for HPV. The vaccine uptake rate, although increasing, has been slow. Conclusion: College-aged women in the United States may need unbiased information about HPV and HPV vaccine. Studies that focus on risk perception and the relationship between knowledge, attitudes, vaccine uptake, and sexual behaviors are needed to inform interventions and public health programs.     

Alternative Medicine and Herbal Use Among University Students

Abstract

Objective: This study sought to (1) examine perceived stress and resources to cope with stress as predictors of emotional eating during the transition to college and (2) determine whether body mass index (BMI) moderated the emotional eating-stress relationship. Participants: Participants were 97 college freshmen (73% female; BMI: M = 25.3 kg/m², SD = 5.7 kg/m²). Research was conducted in September 2012. Methods: Participants completed the Perceived Stress Scale, Emotional Eating Scale, and Eating and Appraisal Due to Emotions and Stress Questionnaire during the first month of college. Height and weight were measured objectively. Results: BMI moderated the relationship between perceived stress and emotional eating. Higher stress predicted greater emotional eating for the lower BMI groups, but not the highest group. Greater resources to cope with stress predicted lower emotional eating. Conclusions: Greater perceived stress and poorer resources to cope with stress may contribute to emotional eating during the transition to college. The relationship between perceived stress and emotional eating may vary by BMI.     

Principles of Total Quality Management and Their Application to Employee Assistance Programs:

Total quality management (TQM) has been thrust into the psyche of corporate America. TQM is not a new phenomena. Introduced in the early fifties to Japanese managers by an American management expert, it served to make Japan an international economic leader. U.S. companies have generally had little international competition. They now recognize he formidable challenge that quality based companies represent and are striving to replicate these successes. To do so will be to remain competitive. To discount the impact of TQM initiatives could spell economic disaster. Employee assistance program (EAP) management is modeled after American management principles. EAPs are also now having to compete for market share in ways for which they were never prepared. The TQM initiatives currently being implemented in many companies may be applied equally well to EAPs. This article presents an overview of the TQM principles formulated by W. Edwards Derning. The article also attempts to critically analyze some of the areas that have been problematic in EAP management. Further, it examines how TQM initiatives could serve to ameliorate some of these problems and lend additional impetus to the competitiveness of employee assistance programs with other behavioral health care service delivery and cost management programs.
