Abstract

The relative importance of university versus work setting socialization experiences and the combined effects of these experiences on professional role orientation is assessed via path analysis for a sample of 1580 engineering and science graduates of a large midwestern university. As hypothesized, the following experiences positively effect professional role orientation: science training; attainment of the Ph.D.; autonomy as a graduate student; knowledge of faculty who endorse the scientific ethos; assignment to an R&D function and exercise of high levels of technical responsibility in initial and current jobs. In general, professional orientation results less from work setting influences than from graudate school training. One exception is that respondents who exercise high levels of technical responsibility in 1965 show a stronger professional orientation than their less successful colleagues.  相似文献

This study examines the impact, relative importance, and unique predictive validity of changes in a host of job features and other relevant factors on job satisfaction over a 35-year period using data from the 1979 National Longitudinal Survey of Youth cohort (12,686 respondents). The design of our analysis eliminated of the impact of established between-person correlates of job satisfaction (e.g., personality, cognitive ability), thereby providing for direct examination of within-person change in the focal variables. Results using a first-difference regression and a relative weights analysis revealed that changes in intrinsic, social, and extrinsic features corresponded to changes in satisfaction, but with differing magnitudes. Specific features (e.g., different dimensions of the Job Characteristics Model) generally were unique predictors when all variables were considered. Findings regarding the importance of various features substantially deviate from employees’ reports about contributors to job satisfaction and, in some cases, also differ from findings drawn from cross-sectional data.

Flood insurance is a critical risk management strategy, contributing to greater resilience of individuals and communities. The occurrence of disasters has been observed to alter risk management choices, including the decision to insure. This has previously been explained by learning and behavioral biases. When it comes to flood insurance, however, federal disaster aid policy could also play a role since recipients of aid are required to maintain insurance. Using a database of flood insurance policies for all states on the Atlantic and Gulf coasts of the United States between 2001 and 2010, this article uses fixed effects models to examine how take‐up rates respond to the occurrence of hurricanes and tropical storms, as well as disaster declarations and aid requirements. Being hit by at least one hurricane in the previous year increases net flood insurance purchases by 7.2%. This effect dies out by three years after the storm. A presidential disaster declaration for floods increases take‐up rates by 6.7%. When disaster aid grants are made available to households, take‐up rates increase by 5%; this accounts for the majority of the increase in policies after occurrence of a hurricane. When the models are estimated taking into account which policies are required by disaster aid, hurricanes are estimated to lead to only a 1.5% increase in voluntary purchases. This overlooked federal policy that disaster aid recipients insure is responsible for a majority of insurance purchases postdisaster.  相似文献

The concept of control is a prominent component of theories of stress. From a transactional framework, appraisal of control is seen as important in influencing coping behaviour. However, little attention has been paid to the measurement of the appraisal of control in a work-related situation. In this paper it is argued that situational control should not be reduced to a simple assessment of whether or not an individual has control over a given situation. Instead it is believed that it is important to identify the factors that an individual strives to have control of, as well as the perceived degree of control over those factors. A major component of the present study was the use of a measure that viewed control in this way and that examined control as a multifaceted construct (task control, predictability, self-control and general control). This paper reports on an analysis that examines the multifaceted nature of perceived control with other situational appraisals in the process of coping with workplace stress. A total of 134 employees from four public sector organizations in New Zealand took part in this research. Having control over work tasks was for this sample considered to be less important in giving a sense of control than either predictability or self-control. When it came to reporting how much control they actually had, respondents reported higher levels of self-control than other aspects of control. However, in general respondents reported lower levels of actual control than what they perceived it was important for them to have. This research emphasizes the importance of having a sense of self-control, particularly when it comes to the use of different coping strategies. Overall these findings point to the need to better understand the nature and type of control and its importance if we are to advance our knowledge of work stress.  相似文献

Using the 1994–1995 National Longitudinal Study of Adolescent Health, we examine the association between closeness with parents and teen beliefs regarding the consequences of pregnancy. Unlike previous studies in this area, we include measures of closeness to both mother and father and examine effects for both male and female adolescents by family type (two-biological- or two-adoptive-parent, stepfather, and single-mother families). Our findings indicate that parental closeness is most salient for boys living with two biological or adoptive parents. For girls living with two biological or adoptive parents and boys and girls living in stepfather families, controlling for other aspects of the parent-child relationship, as well as adolescent, socioeconomic, and demographic characteristics, eliminates the protective influence of closeness to parents. For teens living in single-mother families, closeness with mother has no effect on beliefs about the consequences of pregnancy. Overall, our findings indicate that it is teen beliefs regarding parental viewpoints on educational achievement and engagement in sexual activity, rather than closeness per se, that has the link to adolescent beliefs about the consequences of pregnancy.  相似文献

Hurricane Katrina did massive damage because New Orleans and the Gulf Coast were not appropriately protected. Wherever natural disasters threaten, the government—in its traditional role as public goods provider—must decide what level of protection to provide to an area. It does so by purchasing protective capital, such as levees for a low-lying city. (“Protection” also consists of prohibiting projects that raise risk levels, such as draining swamps.) We show that if private capital is more likely to locate in better-protected areas, as would be expected, then the marginal social value of protection will increase with the level of protection provided. That is, the benefit function is convex, contrary to the normal assumption of concavity. When the government protects and the private sector invests, there may be multiple Nash equilibria due to the ill-behaved nature of the benefit function. Policy makers must compare them, rather than merely follow local optimality conditions, to find the equilibrium offering the highest social welfare. There is usually considerable uncertainty about the amount of private investment that will accompany any level of protection, further complicating the government’s choice problem. We show that when deciding on the level of protection to provide now, the government must take account of the option value of increasing the level of protection in the future. We briefly examine but dismiss the value of rules of thumb, such as building for 1000-year floods or other rules that ignore benefits and costs.  相似文献
