The benefits of programme review, forward planning and control have been demonstrated at the university-wide level. Within a faculty or department, there is also a clear need for developing and using planning methods which are rationally based and forward looking if appropriate responses to changing social and academic trends are to be made. This paper delineates a number of planning and control variables encountered at the faculty or departmental level, describes the development and use of a computer-based interactive forecasting model, and discusses the advantages and limitations of such models in planning a faculty's progress toward its goals. 相似文献

This paper describes how 23 primarily upper-middle-class high school seniors anticipated identity changes as they prepared to leave home for college. The transition from high school to college is a period of “liminality” during which students are structurally in between old and new statuses. We discuss how students anticipated change, planned to affirm certain of their identities, imagined creating new identities, and contemplated discovering unanticipated identities. Such interpretive effort must be understood in the context of the ambivalence they felt about leaving home and achieving independence. The data also provoke discussion of how social class membership might be implicated in people's ability to control identity change as they move through the life course. 相似文献

Functional avoidance as an intermittent coping mechanism is a necessary component in disaster recovery. By temporarily avoiding losses after disaster, survivors can secure basic needs and begin rebuilding. It is not until recovery projects are completed that mental health outcomes become apparent. Many individuals begin a healthy grieving process; however, for others, where avoidance extends past the completion of normalizing tasks it becomes pathological. This study presents the concept of functional avoidance and investigates the point at which it becomes dysfunctional using case examples and data from a mental health clinic. Findings suggest increased emotional distress, depression, and posttraumatic stress disorder over 3 years after Hurricane Katrina. 相似文献

Abstract. Objectives: This study explored God locus of control beliefs (ie, God's control over behavior) regarding their influence on alcohol use and sexual behavior as an alternative religiosity measure to religious behaviors, which does not capture perceived influence of religiosity. Additionally, demographic differences in religious beliefs were explored. Methods: College students aged 18–24 (N = 324) completed a survey between April 2012 and March 2013. Principal components and multivariate analyses were conducted. Results: Findings suggest that measures provide reliable, valid data from college students. God locus of control is linked to not consuming alcohol or engaging in sex. There were differences regarding relationship status and religious denomination. Conclusions: God locus of control beliefs are an appropriate construct for collecting data about college students’ religiosity. Furthermore, health educators at faith-based institutions could incorporate this construct into their programming, encouraging abstinence but also behaving responsibly for those who do drink and are sexually experienced. 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

This article examines how parents experience the process of “letting go” of their college‐bound children. The focus of our analysis is on how the parents evaluate the meanings of their children's leaving home and adopt strategies to facilitate the process for both themselves and the departing child. Our analysis is based on interviews with thirty sets of parents. The interview materials allowed us to recognize and then parse the paradoxical task faced by parents of fostering “attached individuation” for both themselves and their children. We address four broad and persistent themes that emerged from our conversations with parents. First, we consider how parents manage the range of sometimes‐conflicting emotions generated by the letting go process. Second, we analyze the content of parents' worries as a good unobtrusive measure of how they understand the transition to college as a ritual marker in their children's lives. Third, we show how negotiations about geography—about proper distance from home—in choosing a college reflect efforts to impose a measure of gradualism into the letting go process. Fourth, we report on how parents theorize the impact of a child's departure on family relationships in general. 相似文献
