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

This study assesses the fire safety risks associated with compressed natural gas (CNG) vehicle systems, comprising primarily a typical school bus and supporting fuel infrastructure. The study determines the sensitivity of the results to variations in component failure rates and consequences of fire events. The components and subsystems that contribute most to fire safety risk are determined. Finally, the results are compared to fire risks of the present generation of diesel-fueled school buses. Direct computation of the safety risks associated with diesel-powered vehicles is possible because these are mature technologies for which historical performance data are available. Because of limited experience, fatal accident data for CNG bus fleets are minimal. Therefore, this study uses the probabilistic risk assessment (PRA) approach to model and predict fire safety risk of CNG buses. Generic failure data, engineering judgments, and assumptions are used in this study. This study predicts the mean fire fatality risk for typical CNG buses as approximately 0.23 fatalities per 100-million miles for all people involved, including bus passengers. The study estimates mean values of 0.16 fatalities per 100-million miles for bus passengers only. Based on historical data, diesel school bus mean fire fatality risk is 0.091 and 0.0007 per 100-million miles for all people and bus passengers, respectively. One can therefore conclude that CNG buses are more prone to fire fatality risk by 2.5 times that of diesel buses, with the bus passengers being more at risk by over two orders of magnitude. The study estimates a mean fire risk frequency of 2.2 x 10(-5) fatalities/bus per year. The 5% and 95% uncertainty bounds are 9.1 x 10(-6) and 4.0 x 10(-5), respectively. The risk result was found to be affected most by failure rates of pressure relief valves, CNG cylinders, and fuel piping. 相似文献

Data from a five percent census sample reveal that in Guatemala City in 1964 economically active women, especially domestic servants, had lower cumulative fertility than inactive women, partly because larger proportions of them had never married and were childless. However, even among ever married mothers there was a substantial differential, which was not due to differences in age at first birth. With respect to all women, cross tabulation and regression analysis show that age, marital status and educational attainment were more strongly associated with fertility than was activity status, but the latter also had a significant net association. Selection for sterility was not likely. Being contrary to expectations expressed in the literature, the very low fertility of the domestics received further attention. Live-in domestics had considerably lower fertility than those who lived out, which was also the case in the United States in 1960. These data and other evidence strongly suggest that this differential is due to a widespread employer preference for single or childless women. The concept of role incompatibility is therefore inapplicable to domestic servants. These findings add to the considerable evidence showing lower fertility among economically active women in large urban places in Latin America. 相似文献

Suicide among adolescents is increasing. Three interacting factors—the crisis of adolescent development, family dysfunctioning, and social factors—create vulnerability to feelings of rejection and worthlessness among suicidal adolescents. Long-term family problems that are not openly acknowledged but for which the adolescent feels responsible are particularly relevant. The authors recommend a multiple approach to assessment and treatment in which crisis intervention is employed initially; and individual treatment for the adolescent and family therapy are utilized concurrently on a long-term basis. 相似文献
