Abstract

The authors surveyed 614 African American university students to determine the magnitude of cigarette use, identify risk factors, and develop models to predict smoking. More than half (58.3%) of the participants had smoked at least once, and 9.3% of that group were lifetime smokers. Among the lifetime smokers, 71.3% had smoked during the 30 days preceding the survey. More women (66.8%) than men (56.1%) had tried smoking and were classed as lifetime smokers. Residence, parental, and peer smoking (current and childhood) were associated with trying smoking; age, race/ethnicity, and marital status were additional factors for becoming a lifetime smoker. The risk of being a lifetime smoker was reduced when neither friends nor parents of the student smoked and the student viewed spirituality as important. The results of this study add to the growing understanding of health risk behaviors among African Americans and can be useful in reducing smoking.  相似文献

The increasing organizational size, as a result of the industry's structural change, is leading to crises in German horticultural companies. Therefore, the present study examines the causes of fundamental change processes in horticultural companies, indicates the overriding trends and identifies the success factors of change initiatives. For this purpose, over 150 decision-makers with over 10 years’ experience in their respective organization were surveyed from May to December 2014. The megatrends are environmental issues, changed consumer behavior, resource shortages and the labor market. Currently, the reasons for change lie in a changing market strategy/sales approach, business succession and submission and external changes in the legal conditions. Among the most difficult problems occurring in the implementation of change processes are low willingness to take responsibility, interest and goal conflicts of the involved organization's members and a sacrifice of long-term actions for short-term profit improvements. The most important success factors of change processes include realistic, clear visions/goals and their communication, team spirit and motivation and a coordinated chronological procedure. Six factors of the psychological level of the change success are presented. The results of the study can help to recommend a design for change processes in companies within horticultural manufacturing.  相似文献

This article examines the professional culture of a UK symphony orchestra and the ways the musicians perceive themselves as a Community of Practice (CoP). The study draws on data from semi-structured interviews. Findings illuminated aspects of a CoP among the musicians, including having a shared purpose, valuing their collective endeavor, and experiencing tension between individual and collective development. These elements provide insights for our understanding of CoP, and highlight critical aspects of musical and interpersonal interactions that emerging professional musicians and advanced students need to develop and skillfully balance if they are to operate effectively within an orchestral CoP.  相似文献

The present research examined the relationship between supportive and controlling dimensions of parenting behaviors and Chinese adolescent outcomes (school adjustment and problem behavior). Researchers collected self-report data from 589 adolescents in Hangzhou, China. Results showed the factor structure for the Parent Behavior Measure in the Chinese sample was different from the factor structure based on Western research. Specifically, paternal support did not emerge as a viable factor. Parental monitoring and involvement predicted positive adolescent outcomes, whereas punitiveness and permissiveness predicted negative outcomes. Surprisingly, maternal support predicted more adolescent problem behavior, especially for boys. Guilt induction, love withdrawal, and positive induction did not predict any significant adolescent outcomes when other parenting behaviors were controlled. School adjustment mediated and gender moderated the relationship between parenting and adolescent problem behavior. The importance of considering parenting behaviors, adolescent school adjustment, gender, and cultural norms when examining adolescent problem behavior was discussed.  相似文献

In a service environment a service provider needs to determine the amount and kinds of capacity to meet customers’ needs over many periods. To make good decisions, she needs to know the probability distribution of her customers’ demand in each period. We study a situation in which customers’ demand for a given service is random in each period, but inelastic, or modeled well by this assumption, and cannot be delayed to the next period. This article presents a mechanism that allows a service provider to learn the distribution of a customer's demand by offering him a set of contracts through which he can partially prepay for future service for a reduced cost for units of service based on anticipated needs. We describe the form of a set of contracts that will cause the customer to reveal his demand distribution as he minimizes his expected costs. To justify the effort of organizing and offering contracts, we present an application that demonstrates the cost savings to the service provider with better capacity planning using the truthfully elicited distribution.  相似文献

Recent studies have found size of territorial units to vary inversely with population density, the only exception to this regularity being Great Britain, where size and density were found to be unrelated. The present research accounts for this anomaly by demonstrating Britain's historical conformity to the size-density relation. The size-density hypothesis is further supported by direct test, made possible by a recent reorganization of british counties. Results show that reorganization has restored the expected inverse relation between size and density and has restructured the size and density of counties in a manner precisely specified by underlying theory.  相似文献

This study analyzes consumers’ knowledge of their own credit situation and tests whether a lack of knowledge affects financial outcomes. The unique dataset from survey and credit report data includes self-estimates of credit scores and actual scores from a low-to-moderate income sample. We argue and show empirically that many respondents don’t know their credit score and generally underestimate their creditworthiness. Furthermore, our evidence suggests that this biased self-assessment may explain differences in perceived credit constraints and credit contracts, specifically credit card interest rates. Our research suggests that an important aspect of financial literacy is self-assessment, and that it is important to encourage consumers to regularly check their credit reports and scores so as to better understand their actual creditworthiness.  相似文献

Family relations and economic issues may predict stress in two-generation farm families. Marital adjustment, length of time married, income satisfaction, and number of household dependents are examined as predictors of stress for each family member (i.e., separately for each member) using multiple regression analyses. The model is significant for fathers with marital adjustment, length of time married, and income satisfaction significantly contributing to fathers' stress. The model is not significant for mothers, sons, or daughters-in-law; but income satisfaction is significantly related to stress for mothers. Implications for researchers and practitioners are discussed.Support for this research was provided by the Montana Agricultural Experiment Station Grant No. MONB00266 and is part of the AES Western Regional Project W-167.Stephan M.
