This study investigated relationships among factors hypothesized as related to job loss grief. A summary grief score correlated positively with time since job loss and number of dependents, and negatively with length of notice. Perceived reemployment prospects and income loss related positively to some grief index subscales, as did the condition of living on one's own. Job duration correlated negatively with some grief responses. Implications for counseling and avenues for future research are discussed. 相似文献

The relationship between daily pollen counts during the peak pollen season and hay fever symptoms in known sufferers of pollen allergy was investigated in a Sydney hospital‐based study. This paper develops statistical models for both the short term (day to day) associations and the longer term relationships between these time series. Possible effects of asthma status are investigated. The analyses illustrate how different relationships between time series may be explored in a simple way by working on different time scales with suitably transformed variables. 相似文献

该文首先介绍了社会心理学中的归因理论,并结合作者的实际工作,论述了归因理论对数学教学工作的指导意义。它包括:教师必须弄清学生学习失败的真正原因,帮助学生树立自信心,并不断使其体验到因具备能力并加上自身的努力后取得成功的喜悦;强调经过努力获得成功也是学生自身能力的体现。教师应努力使学生深信,他们所要完成的学习任务是很有价值的,能够通过自我控制达到最佳的效果。 相似文献

Summary. Suppose that we have m repeated measures on each subject, and we model the observation vectors with a finite mixture model. We further assume that the repeated measures are conditionally independent. We present methods to estimate the shape of the component distributions along with various features of the component distributions such as the medians, means and variances. We make no distributional assumptions on the components; indeed, we allow different shapes for different components. 相似文献

The number of suicides reported for New York City by the National Center for Health Statistics (NCHS) fell precipitously in 1985 and remained extremely low until 1989, when it returned to pre‐1985 levels. The downturn in reported suicides from 1985 to 1988 occurred in all five of the city's boroughs but did not extend to the suburbs. The apparent drop in suicide rates was largely and perhaps completely an artifact of personnel and policy changes in the New York City Chief Medical Examiner's Office during a period in which the office engaged in defensive structuring in the face of severe political, economic, and journalistic pressures. During the downturn, suicides were “hidden” in reported deaths attributable to non‐motor‐vehicle accidents and, to a lesser extent, undeter‐mined external causes. The socially constructed trough in suicide rates between 1985 and 1988 affects the outcome of tests of theories of suicidal behavior using county‐level data for New York State. 相似文献

Conclusion This article has presented a vision of what a field of altruism and social solidarity could potentially involve. An additional
perspective on the nature of this field and how it could contribute to the discipline and to society is provided by the science
of psychology. In the last decade a fundamental new orientation has developed in this discipline, growing from the pioneering
work of Martin E.P. Seligman. Generally identified as “positive psychology” it represents a shift from a focus on trying to
understand and find solutions to mental illness and various pathologies of thought and behavior in a “disease model” to a
focus on human strengths, virtues, and other positive characteristics. This shift in focus is regarded as making a direct
contribution to understanding what is best in human emotions and traits and how society can support the psychological flourishing
of individuals. This new perspective in turn provides increased awareness of how the problems studied in the disease model
can more effectively be prevented (Seligman, 2003, 2005). The importance of this focus on the positive for sociology and a
call to action is stated by Seligman (2003): The third pillar of positive psychology is the study of positive institutions
and positive communities. 相似文献

It is widely accepted that regular physical exercise helps diabetic patients control blood glucose, reduce cardiovascular risk factors, and prevent other related complications. In spite of the undoubted benefits of regular physical exercise, diabetic patients with chronic complications should be aware of potential hazards of practicing exercise. To avoid some harmful consequences of acute exercise, it is necessary to adopt a vigilant attitude with these risk patients and to carefully adjust type and intensity of exercise to the individual situation. This article intends to summarize and analyze the current literature concerning the preventive and therapeutic effects of regular exercise in diabetic patients, pointing out its physiological influence on blood glucose regulation, and to analyze the potential risks of acute physical exercise and the precautions given to patients with a variety of complications. 相似文献

Abstract. Let π denote an intractable probability distribution that we would like to explore. Suppose that we have a positive recurrent, irreducible Markov chain that satisfies a minorization condition and has π as its invariant measure. We provide a method of using simulations from the Markov chain to construct a statistical estimate of π from which it is straightforward to sample. We show that this estimate is 'strongly consistent' in the sense that the total variation distance between the estimate and π converges to 0 almost surely as the number of simulations grows. Moreover, we use some recently developed asymptotic results to provide guidance as to how much simulation is necessary. Draws from the estimate can be used to approximate features of π or as intelligent starting values for the original Markov chain. We illustrate our methods with two examples. 相似文献
