This paper discusses the use of risk and resilience theory to understand how individuals and communities respond to natural disasters that present ongoing developmental challenges to personal and collective well-being. In the past two to three decades, mental health workers have developed numerous disaster relief strategies; while economists have become expert at estimating risk. These develops are explored.  相似文献

Children (aged 9, 14, 19, and 24 months) were encouraged to use tools to achieve a demonstrated goal. Each tool was most efficiently applied when held by the handle with the thumb toward the head of the tool in a radial grip. The tools were presented at midline and oriented to the left and right on alternating trials, so the children who managed to grasp a tool in both orientations with the radial grip demonstrated planning of actions in advance. The tools included a spoon, hairbrush, toy hammer, and magnet; the goals were to feed one's self, feed another, brush one's hair, brush another's hair, hit pegs, and retrieve metal objects. Children were found to use more radial grips with the self‐directed tools (i.e., hairbrush‐to‐self and spoon‐to‐self), indicating that they could plan their actions better when directed toward the self than toward an external goal.  相似文献

We describe a one-dimensional probabilistic model of the role of domestic food handling behaviors on salmonellosis risk associated with the consumption of eggs and egg-containing foods. Six categories of egg-containing foods were defined based on the amount of egg contained in the food, whether eggs are pooled, and the degree of cooking practiced by consumers. We used bootstrap simulation to quantify uncertainty in risk estimates due to sampling error, and sensitivity analysis to identify key sources of variability and uncertainty in the model. Because of typical model characteristics such as nonlinearity, interaction between inputs, thresholds, and saturation points, Sobol's method, a novel sensitivity analysis approach, was used to identify key sources of variability. Based on the mean probability of illness, examples of foods from the food categories ranked from most to least risk of illness were: (1) home-made salad dressings/ice cream; (2) fried eggs/boiled eggs; (3) omelettes; and (4) baked foods/breads. For food categories that may include uncooked eggs (e.g., home-made salad dressings/ice cream), consumer handling conditions such as storage time and temperature after food preparation were the key sources of variability. In contrast, for food categories associated with undercooked eggs (e.g., fried/soft-boiled eggs), the initial level of Salmonella contamination and the log10 reduction due to cooking were the key sources of variability. Important sources of uncertainty varied with both the risk percentile and the food category under consideration. This work adds to previous risk assessments focused on egg production and storage practices, and provides a science-based approach to inform consumer risk communications regarding safe egg handling practices.  相似文献

Presidential Address on ALTRUISM AND SOCIOLOGY   总被引:1,自引:0,他引:1  
This article concerns the study of altruism. Highlights of the research history of altruism in sociobiology, psychological social-psychology, and sociology are reviewed. Examples from the author's work on kidney and bone-marrow donation are interwoven with this history. The sociological mechanisms producing altruism, particularly normative obligation, are emphasized along with the psychological mechanisms (e.g., empathy). The need for better integration across subareas in sociology is discussed. In addition, it is concluded that some scientific work significantly trivializes altruism.  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

The prudent reader who does not understand something in a research report should inquire of the researcher concerning the precise nature of the problem. Had Professor Kuz contacted me, Professor Latif (then working half-way across town from him), or some third party knowledgable in the field in this regard, he would have been spared the embarrassment of committing more mistakes than I can hope to identify in this short space. I would have been spared the time and trouble to locate and correct them. The Review would have been spared the unhappy task of keeping some worthy contribution unpublished while choosing to publish Professor Kuz' comments.  相似文献

The present study investigates the dimensional structure of the psychosocial work environment as assessed by Karasek's job characteristics scales and a set of factorial scales derived from the Dictionary of Occupational Titles (DOT) observers' ratings of occupational characteristics for census occupations. Scale scores on the Karasek and DOT were linked to information on occupation from the Epidemiologc Catchment Area (ECA) study sample. Scale intercorreladons and factor analysis were performed on those ECA subjects who reported ever having a full-time job (n=11,789). DOT'sS Substantive Complexity scale was positively correlated with Karasek's Skill Discretion and Decision Authority scales, and DOT's Physical Demands and Hazards scale was positively correlated with Karasek's Physical Demands scale. In addition, the DOT system compared to the Karasek system seems to assess psychosocial work domains less characteristic of traditional industrial jobs (interpersonal stress, expressive work). The content validity of the Karasek scales might be increased with the assessment of these domains. Giving support to Karasek's Demand/Control Model, the factor structure of the psychosocial work enviromnent in the probability sample of five US metropolitan populations yielded two major dimensions: Control, and Physical Demands.  相似文献

Collective violence is often social control: self-help by a group. It typically defines and responds to conduct as deviant. When unilateral and nongovernmental, it appears in four major forms—lynching, rioting, vigilantism, and terrorism—each distinguished by its system of liability (individual or collective) and degree of organization (higher or lower). Following Donald Black's paradigm of pure sociology, the central assumption is that collective violence varies with its location and direction in social space—the conflict structure. I offer ten propositions that predict and explain the likelihood and severity of collective violence in general and the four forms of collective violence in particular. Conflict structures with a high degree of relational distance, cultural distance, functional independence, and inequality between the adversaries are associated with collective violence in general. Each of the four forms depends on the degree of social polarization between the parties as well as the continuity of the deviant behavior to which the violence responds. Earlier versions of this paper were presented at the Annual Meeting of the American Sociological Association, Pittsburgh, Pennsylvania, August 1992, and the Centennial Congress of the International Institute of Sociology, University of Paris (Sorbonne), Paris, June 1993.  相似文献
