Preregulation estimates of benefits and costs are rarely validated after regulations are implemented. This article performs such a validation for the mandatory automobile airbag requirement. We found that the original 1984 model used to estimate benefits became invalid when 1997 values were input into that 1984 model. However, using a published 1997 cost-effectiveness model, we demonstrate, by replacing the model inputs with the values from 1984, that the 1997 cost-effectiveness ratios, based on real-world crash data and tear-down cost data, are less attractive than what would have been originally anticipated. The three most important errors in the 1984 input values are identified: the overestimation of airbag effectiveness, the overestimation of baseline fatality/injury rates, and the underestimation of manual safety belt use. This case study, which suggests that airbags are a reasonable investment in safety, shows that the regulatory analysis tools do not always produce findings that are biased against health, safety, and environmental regulation. Future validation studies of health, safety, and environmental regulation should focus on validation of benefit and risk estimates, areas where we found significant error, as well as on cost estimates. 相似文献

Male pathological gamblers entering a comprehensive treatment program were followed-up for twelve months after treatment completion. Twelve month follow-up was obtained for 45 of the 66 patients entering treatment. Total abstinence was reported by 55% (n=25) of the patients located for twelve month follow-up. A relationship was found between abstinence at six month follow-up and selected subscales of the Wechsler Adult Intelligence Scale, performance scale. The implications of these findings for sub-typing gamblers are discussed. 相似文献

The importance of coping skill enhancement in the treatment of pathological gamblers is discussed. It is particularly critical to assess and enhance the coping skills of relapse prone gamblers who are marked by unusual degrees of impulsivity, high levels of negative affect and feelings of helplessness and hopelessness. A study of 1129 substance abusers, including 140 with serious gambling problems is reported. All were assessed to determine their repertoire of coping skills. The patients with serious gambling problems utilized significantly more avoidant and impulsive coping styles. 相似文献

1. Patients with post-traumatic stress disorder (PTSD) often encounter treatment that is complicated by professional bias, personal issues, countertransference, and pathological staff dynamics. 2. Treatment is further complicated by diagnostic confusion, the dual diagnoses of substance abuse or depression, and symptoms that mimic personality disorders or psychosis. 3. The special circumstances of the Vietnam conflict that contributed to the susceptibility and etiology of PTSD are the individual characteristics of those who served, the special nature of the war itself and the military strategies used, and the psychosocial and cultural milieu in which it occurred. 相似文献

Managerial value and belief systems in a cross-national context: The case of thetrivial significance
This article discusses potential theoretical and methodological flaws in value-based research in a cross-national context. Using data from a comparative study of American and Indian CEOs, it is shown that some managerial beliefs and value systems do vary as a function of national background. While this is neither surprising nor exciting, whether this significantheterogeneity offers nontrivial predictive utilityin explaining the observed variance in a large number of structural, strategic, and other critical variables at the organizational level is the more important question. This study offers preliminary evidence to the contrary.In this era of multinational corporations and an emerging global market for executive and managerial talent, the question of whether some managerial beliefs and value systems persist in spite of extensive acculturation and socialization has been an issue of concern — especially in the United States because of a large and continuing flow of immigrants. Our results show in essence that this question, though important and interesting from a sociological angle, is perhaps not as crucial as one might suppose in influencing the strategic thrust, structural configurations, or certain aspects of performance of an organization. 相似文献

Confederate asset price stabilization policies appear to have increased the velocity of circulation and counterproductively channeled inflationary pressures into other areas of the economy. Three successive monetary reforms encouraged holders of Treasury notes to exchange these notes for bonds by imposing deadlines on their convertibility. We show that Confederate funding acts aimed at precipitating the conversion of currency into bonds did temporarily suppress currency depreciation. These acts also triggered upsurges in commodity prices, however, because note holders rushed to spend the currency before their exchange rights were reduced. 相似文献

The distinctive economic histories of African American and White wives suggest that involvement in household income production holds contextually situated unique meanings for these groups. Yet research has not addressed racial differences in the effects of relative earnings on marital well‐being. Surveying 431 employed wives in 21 U.S. cities, we found that wife‐to‐husband income ratio and marital happiness were negatively associated when women held traditional values, but in racially distinct ways. Among White women only, a negative association between income ratio and marital happiness was reversed when financial need was reported. Findings are discussed in terms of variability in the meaning of wives’ earnings as a function of situational, historical, and sociocultural dynamics. 相似文献
