This study examined positive and negative outcome expectancies for risk behaviors, and their association with engagement in risk behaviors, in a sample of 149 maltreated adolescents. “Outcome Expectancies” are evaluative social cognitions about what will occur as a consequence of one's actions. Risk behaviors and outcome expectancies for substance use, sexual behavior, and delinquency were assessed. In all regression models, positive expectancies were significantly related to risk behaviors while negative expectancies, with one exception, were not significantly related. In three of four regression models, significant interactions were found between positive and negative expectancies in predicting risk behaviors. The nature of the interaction differed by type of risk behavior. Beyond demonstrating associations between outcome expectancies and risk behaviors in a maltreated sample, this paper contributes to the study of social information processing by demonstrating significant interactions between positive and negative expectancies. 相似文献

Russian regions display remarkably different patterns of economic and political development. These differences come into sharp focus when comparing two nearly identical northwestern regions, Novgorod and Pskov. Novgorod's success and Pskov's failure are attributed to the local elite's creative use of key cultural symbols and myths to support regional development. Contrasting two popular approaches to culture and development—“cultural adjustment” and “cultural congruence”—the author argues that the cultural congruence model, adopted by Novgorod, dramatically improves the chances for rapid social and economic transformation. 相似文献

In certain abnormalities of spinal shape, the long axis of the spine moves out of the median sagittal plane, producing both an axial torsion and a lateral deviation out of the usual front-back plane. Clinicians need to be able to assess rapidly and accurately whether or not an individual has such an abnormality. In this paper, we examine several case studies. These are analyzed using some simple summary statistics, and the use of these methods to infer abnormality is demonstrated. Using a simple fitted model for the data, an angular estimate of abnormality is obtained. Empirical measures of abnormality based on the eigenvalues of the covariance matrix are also determined. These methods are applied to a number of individuals for whom the surface spinal profiles have been recorded and who have been assessed as normal or abnormal by clinicians. 相似文献

Environmental policymakers and regulators are often in the position of having to prioritize their actions across a diverse range of environmental pressures to secure environmental protection and improvements. Information on environmental issues to inform this type of strategic analysis can be disparate; it may be too voluminous or even absent. Data on a range of issues are rarely presented in a common format that allows easy analysis and comparison. Nevertheless, judgments are required on the significance of various environmental pressures and on the inherent uncertainties to inform strategic assessments such as “state of the environment” reports. How can decisionmakers go about this type of strategic and comparative risk analysis? In an attempt to provide practical tools for the analysis of environmental risks at a strategic level, the Environment Agency of England and Wales has conducted a program of developmental research on strategic risk assessment since 1996. The tools developed under this program use the concept of “environmental harm” as a common metric, viewed from technical, social, and economic perspectives, to analyze impacts from a range of environmental pressures. Critical to an informed debate on the relative importance of these perspectives is an understanding and analysis of the various characteristics of harm (spatial and temporal extent, reversibility, latency, etc.) and of the social response to actual or potential environmental harm from a range of hazards. Recent developments in our approach, described herein, allow a presentation of the analysis in a structured fashion so as to better inform risk‐management decisions. 相似文献

The literature argues that income growth leads to increased demand for environmental quality and thus reduction in pollution. Using a utility theoretic model, we hypothesize that the income–pollution relationship should depend on the level of disamenity of the pollutant. We proxy for disamenity using the toxicity of releases. For counties in the United States, the functional relationship between income and releases depends on the level of disamenity: the form is more concave for more toxic releases. We find that environmental improvements occur at lower levels of per capita income for more toxic pollutants. 相似文献

Predictors of prenatal and postnatal parenting efficacy were examined in a sample of 115 primiparous mothers and 73 fathers in an effort to examine the association between preexisting parental characteristics and prenatal efficacy and the association between prenatal characteristics and postnatal efficacy when aspects of the current parenting context are taken into account. The most robust predictors of maternal postnatal efficacy included both prenatal efficacy, which significantly predicted postnatal efficacy independent of all other predictors including the current parenting context, and perceived infant temperamental reactivity as both a main effect and as buffered by social support. This was not the case for fathers, whose postnatal efficacy was primarily a function of their amount of involvement in parenting tasks and social support. The differential predictors of mother and father efficacy as well as their implications for future research are discussed. 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
