The present study was designed to examine the effectiveness of Fatal Vision Goggles in reducing intentions to drink and drive. Participants performed a field sobriety task and drove in a traffic simulator while wearing the goggles. A regression analysis was performed in order to predict changes in intentions to drink and drive, using typical drinking patterns, perceived likelihood of getting into a collision when drinking and driving, self efficacy, and driving independence as predictor variables. Results showed that drinking and driving intentions were reduced following the use of Fatal Vision Goggles among those that typically drink more during outings, among those that believe the likelihood of collisions when drinking and driving are greater, and among those less likely to drive to achieve independence and autonomy. These results indicate that Fatal Vision Goggles can be an effective tool in altering drinking and driving attitudes among drivers with specific attitudinal and personal characteristics. 相似文献

Economists may disagree over how much raising the minimum wage increases unemployment, though few argue that the unemployment
effect is zero. According to the standard model, the less the unemployment caused by a minimum wage increase, the less the
harm (or greater the good) that results. But by recognizing that minimum wage workers receive fringe benefits, I show that
increasing the minimum wage may not cause any unemployment and harms workers because it doesn 't. Furthermore, when there
is lumpiness in providing fringe benefits, a minimum wage increase may harm workers by 相似文献

Firms have increased their reliance on flexible, or temporary, employment. Some of this increase is a normal market response
to technological and demographic trends largely beyond the control of public policy. But the trend toward flexible employment
is also explained by increased government regulation of labor markets. This regulation has increased the cost of employing
permanent workers relative to the cost of employing temporary workers. Of primary importance has been the substitution of
regulatory restrictions on hiring and firing for the common law doctrine of employment at will. 相似文献

Traditional sources of sociohistorical data capture only a narrow sense of past lifeworlds. Ethnographic accounts often preserve greater details of social practice but have less clear guidelines for use as data. We evaluate the use of hermeneutical theory as providing guidelines for a method by which ethnographies may be used as sociohistorical data. Hermeneutical analysis of ethnographic "texts" is used to reconstruct patterns of daily life in early-twentieth-century rural Appalachia. This method involves: (1) concept-critique to separate observations from the theoretical framework of the ethnographic account, and (2) validation through a logic of internal consistency and comparison. Through hermeneutical analysis, ethnographics can be made to yield observations of social relations not otherwise available. Our analysis suggests benefits and drawbacks of hermeneutical analysis of ethnographic texts. 相似文献

The implicit definitions we give to career and personal counseling reflect a dichotomy between the two areas of research and practice. The field's research focus and counseling trainees' early practice experience probably reinforce the idea that career counseling is prototypically concerned with young adult career choice. A case study of targeted coaching in business is presented to illustrate how career and personal issues are intertwined in adult career adjustment. 相似文献

Product development occurs in multiproject environments where preemption is often allowed so that critical projects can be addressed immediately. Because product development is characterized by time-based competition, there is pressure to make decisions quickly using heuristics methods that yield fast project completion. Preemption heuristics are needed both to choose activities for preemption and then to determine which resources to use to restart preempted activities. Past research involving preemption has ignored any completion time penalty due to the forgetting experienced by project personnel during preemption and the resulting relearning time required to regain lost proficiency. The purpose of this research is to determine the impact of learning, forgetting, and relearning (LFR) on project completion time when preemption is allowed. We present a model for the LFR cycle in multiproject development environments. We test a number of priority rules for activity scheduling, activity preemption, and resource assignment subsequent to preemption, subject to the existence of the LFR cycle, for which a single type of knowledge worker resource is assigned among multiple projects. The results of the simulation experiments clearly demonstrate that LFR effects are significant. The tests of different scheduling, preemption, and resource reassignment rules show that the choice of rule is crucial in mitigating the completion time penalty effects of the LFR cycle, while maintaining high levels of resource utilization. Specifically, the worst performing rules tested for each performance measure are those that attempt to maintain high resource utilization. The best performing rules are based on activity criticality and resource learning. 相似文献

Although literature on the achievement of monetary objectives in a resource-constrained project environment is limited, the maximization of project net present value (NPV) is an important criterion of project success. This paper presents a procedure for developing a late-start resource-constrained project schedule using the critical path method-material requirements planning. Using an extensive set of problems from the literature, we show that this procedure yields a higher NPV and lower average duration than schedules derived with heuristics that schedule each activity as early as possible. In addition, while the late-start schedule on average was significantly longer than the optimal-duration resource-constrained schedule, no significant difference occurred in the average NPVs of the two scheduling methods. 相似文献

This article completes a characterization of achievable and unachievable hierarchies in weighted voting systems where the quota is a proportion of the total weight, proving the main conjecture of Bean et?al. (Soc Choice Welf 34: 397–410, 2010). 相似文献
