Social work is a stressful occupation but continues to attract large numbers of students every year. This study was conducted by undergraduate students of all three cohorts at a women’s-only college in Tiruchirapalli in South India (N = 73). Standardised instruments to assess stress, anxiety, resilience and coping were administered. It was seen that anxiety and stress levels were relatively higher in the first- and third-year students while compared to those in the second year of their course, while resilience and coping was relatively low in the first-year group. Correlations were significantly positive for the stress and anxiety scores as well as the coping and resilience scores. However, it was seen that only the anxiety scores significantly predicted the manifestation of stress in the students. Implications of the findings and the limitations of the study have also been discussed. 相似文献

针对目前公共英语教学中口语教学的不足,笔者在授课过程中发现,以学生为中心,重视语言综合应用能力和学生自学能力的培养为特色的<新编大学英语>教材,成功地将精读教学和口语教学结合起来.教师采用让学生复述故事、上台表演、看图说话和讨论等方式,在精读课上进行口语练习.这种将两者穿插进行的方式,不失为解决口语教学不足的一个良策. 相似文献

It is pointed out that the familiar analytical device of "event tree", widely used in risk analysis, can be viewed as a transition matrix expressing the likelihood of going from "entry states" to "exit states". This point of view is shown to have numerous interesting conceptual and computational features which promise to make it a very useful addition to the arsenal of tools for risk analysis. The basic idea is explained first in terms of a simple, made-up example. The application of the idea to a very real and complicated problem, nuclear-plant risk assessment, is then outlined. 相似文献

An Alternative Approach to Dietary Exposure Assessment 总被引:4,自引:0,他引:4

The method of dietary exposure assessment currently used by the Environmental Protection Agency (EPA), the Dietary Residue Evaluation System (DRES), combines a consumption distribution derived from the United States Department of Agriculture (USDA) 1977-1978 Nationwide Food Consumption Survey (NFCS) with a single estimate of residue level. The National Academy of Sciences'1 ' recommended that EPA incorporate both the distribution of residues and the distribution of consumption into their exposure assessment methodology and proposed using a Monte Carlo approach. This paper presents an alternative method, the Joint Distributional Analysis (JDA), that combines the consumption and residue distributions, without relying on random sampling or fitting theoretical distributions like the Monte Carlo method. This method permits simultaneous analysis of the entire diet, including assessing exposure from residues in different foods. 相似文献

Reorganization of the NHS in 1974 sped up the process of professionalization of the leadership of the Community Dental Health Services. Since that event public dental officers have gained status through recognition of the need for specialists in community dental health. Nevertheless, by the beginning of 1982 no trainees had yet been appointed to begin the special training programme, thus far failing the efforts of those area dental officers who have striven since 1974 to raise the standards of their successors. 相似文献

Energy constitutes a small fraction of the production inputs in the economy, yet the rigidity imposed by the short and medium term inability to substitute energy with other production factors in case of an energy shortage, requires the establishment of safeguard mechanisms to ensure sufficient energy supply during an emergency. These safeguards usually take the form of strategic energy reserves. A methodological approach is presented here, relating the level of strategic petroleum reserves, the decision variable, with the costs associated with their storage and the economic losses incurred by an energy shortage. This approach is based on the use of a decision tree, to portray emergency scenarios. Each scenario, a branch of the decision tree, can be evaluated in terms of a cost function which includes the inventory procurement and maintenance cost and the shortage cost inflicted by a petroleum shortfall. 相似文献
