OBJECTIVE: The goal of this study was to examine the association between sexual abuse (SA) and initiation, cessation, and current cigarette smoking among a large representative adult population in France. METHOD: A random sample size of 12,256 adults (18-75 years of age) was interviewed by telephone concerning demographic variables, health practices and beliefs, and health status--for which SA and tobacco questions were included. Bivariate and multivariate analyses were conducted. RESULTS: Nearly 46% of SA survivors were current smokers compared to 34% of non-abused persons (p<.001). Survivors of SA consumed more cigarettes per day than non-abused individuals (14.5 vs. 12.4, p<.01). Survival analysis showed an increased risk of smoking initiation for respondents abused before 18 (adjusted relative hazard=1.55; p<.0001) with referent to the non-abused group. SA was not found to be a significant predictor of current smoking status among those who began smoking after the first incident of SA. Respondents who were not sexually abused were 1.8 times (95% CI, 1.12-2.99) more likely to quit smoking than people who began smoking after they were sexually abused. CONCLUSIONS: The early identification and treatment of sexually abused persons is critical to decrease smoking among adolescents and adults because of the association of SA with both smoking initiation and decreased cessation rates. It may be more difficult to detect an association between SA and current smoking due to the high rates of smoking and lower rates of quitting among the general French population.  相似文献

The author gives a personal account of his relationship with his graduate mentor, Allan Schnaiberg. He also describes a mentoring project that he created with a colleague. The mentoring project emerges as both a vehicle for and a window onto the intergenerational transmission of the mentoring disposition of Schnaiberg. It stands as but one of many branches of the expanding influence of Schnaiberg’s life as a scholar, professor, graduate mentor and man. The importance of holistic mentoring is explored, with particular attention to the critical value of its central, affective dimension. Mentoring is particularly important today for non-traditional students, who have a heightened need to feel that they belong in the academic setting. It is suggested that mentoring serves as the guidance function associated with the process by which any being goes through the challenging transition from one cycle, or level of experience, to the next.  相似文献

This research examined the impact of preservice teachers delivering individualized instruction of basic computer skills to at-risk, ethnic minority alternative high school students in an urban school district in South Texas. The alternative high school students' achievement of computer skills, motivation to use computers, and self-efficacy as current and future students was assessed. University preservice teachers taught a keyboard/computer skills curriculum developed specifically for this collaborative teaching and learning project in 10 1-hr-long sessions 2 times a week over a 5-week period. A series of 2 by 2 repeated measures analysis of variance showed achievement gains as measured by a survey instrument within the treatment group. This small, preliminary study supports the use of preservice teachers in the delivery of an individualized, computer-based program of instruction for at-risk students.  相似文献

Previous studies have shown that a predominant tendency in creative generation tasks is to base new ideas on well-known, specific instances of previous ideas (e.g., basing ideas for imaginary aliens on dogs, cats or bears). However, a substantial minority of individuals has been shown to adopt more abstract approaches to the task and to develop more original products as a result. Because domain knowledge is sometimes thought to be associated with more abstract representations, it is possible that these individual differences are linked to how much people have learned about the domain in question. The present study explored the relationship between domain knowledge, the tendency to rely on specific domain instances and both the originality and practicality of outcomes in a task in which participants designed novel sports. In addition to designing novel sports, participants rated their own knowledge about and participation in sports, and they took a short test of sport knowledge. As in previous studies, there were individual differences in approaches to the task, and participants who relied on specific known sports (e.g., basketball) produced less original designs. Neither the measures of sport knowledge nor the measure of sport participation related to the tendency to rely on specific instances in developing the novel sports or to the originality of those creations. However, there were links between tested knowledge and the rated practicality of the designs.  相似文献

The diurnal patterning of locomotion, stereotypy, grooming, eating, drinking, sleeping, postural readjustment, and inactivity was studied in 14 species of muroid rodents in the laboratory using a visual observation technique.Microtus canicaudus, M. montanus, M. ochrogaster, andM. pennsylvanicus exhibited acyclic activity patterns, whilePeromyscus eremicus,P. gossypinus, P. leucopus, P. maniculatus bairdi, P. polionotus, Calomys callosus, Mus musculus, andOnychomys leucogaster displayed nocturnality in their behavioral patterning.Rhabdomys pumilio exhibited crepuscular activities andNeofiber alleni displayed a complex pattern of nocturnality. Species differed in total amount of time spent per day for all activities but eating. The acyclicity ofMicrotus species appears to be related to high metabolic rates and a semifossorial life-style.  相似文献
