The purpose of this study was to explore individual- and school-level policy characteristics on student smoking behavior using an ecological perspective. Participants were 24,213 (51% female) Grade 10–11 students from 81 schools in five Canadian provinces. Data were collected using student self-report surveys, written policies collected from schools, interviews with school administrators, and school property observations to assess multiple dimensions of the school tobacco policy. The multi-level modeling results revealed that the school a student attended was associated with his/her smoking behavior. Individual-level variables that were associated with student smoking included lower school connectedness, a greater number of family and friends who smoked, higher perceptions of student smoking prevalence, lower perceptions of student smoking frequency, and stronger perceptions of the school tobacco context. School-level variables associated with student smoking included weaker policy intention indicating prohibition and assistance to overcome tobacco addiction, weaker policy implementation involving strategies for enforcement, and a higher number of students smoking on school property. These findings suggest that the school environment is important to tobacco control strategies, and that various policy dimensions have unique relationships to student smoking. School tobacco policies should be part of a comprehensive approach to adolescent tobacco use.  相似文献

This study, conducted at the University of Tennessee's Anthropological Research Facility (ARF), lists and ranks the primary chemical constituents which define the odor of decomposition of human remains as detected at the soil surface of shallow burial sites. Triple sorbent traps were used to collect air samples in the field and revealed eight major classes of chemicals which now contain 478 specific volatile compounds associated with burial decomposition. Samples were analyzed using gas chromatography-mass spectrometry (GC-MS) and were collected below and above the body, and at the soil surface of 1.5-3.5 ft. (0.46-1.07 m) deep burial sites of four individuals over a 4-year time span. New data were incorporated into the previously established Decompositional Odor Analysis (DOA) Database providing identification, chemical trends, and semi-quantitation of chemicals for evaluation. This research identifies the "odor signatures" unique to the decomposition of buried human remains with projected ramifications on human remains detection canine training procedures and in the development of field portable analytical instruments which can be used to locate human remains in shallow burial sites.  相似文献

We hypothesised that the responses of pairs of liars would correspond less with each other than would responses of pairs of truth tellers, but only when the responses are given to unanticipated questions. Liars and truth tellers were interviewed individually about having had lunch together in a restaurant. The interviewer asked typical opening questions which we expected the liars to anticipate, followed by questions about spatial and/or temporal information which we expected suspects not to anticipate, and also a request to draw the layout of the restaurant. The results supported the hypothesis, and based on correspondence in responses to the unanticipated questions, up to 80% of liars and truth tellers could be correctly classified, particularly when assessing drawings.

The objective of the study is to assess the impact of emergency department (ED) intimate partner violence (IPV) counseling and resource referrals on patient-perceived safety and safety planning. ED patients with risk factors were offered consultation with trained IPV advocacy counselors who completed safety assessments, provided resource referrals, and helped patients develop safety plans. Patients were contacted after ED intervention to assess progress and further assist in IPV counseling. Over 96% of patients perceived an increase in their safety after the intervention, and approximately 50% had completed a portion of their safety plan. Legal assistance and/or law enforcement were considered the most beneficial resource referrals. Although follow-up was limited, this study appears to demonstrate that an ED IPV intervention program may be useful in helping IPV victims achieve safer living environments and access local resources.  相似文献

Although violent offenders are widely considered to be difficult to engage in therapeutic change, few methods of assessing treatment readiness currently exist. In this article the validation of a brief self-report measure designed to assess treatment readiness in offenders who have been referred to violent offender treatment programs is described. The measure, which is an adaptation of a general measure of treatment readiness developed in a previous work, displayed acceptable levels of convergent and discriminant validity and was able to successfully predict treatment engagement in violent offender treatment. These results suggest that the measure has utility in the assessment of treatment readiness in violent offenders.  相似文献
