Positive school climates and student drug testing have been separately proposed as strategies to reduce student substance
use in high schools. However, the effects of drug testing programs may depend on the favorability of school climates. This
study examined the association between school drug testing programs and student substance use in schools with different climates.
The analysis was based on a nationally representative sample of 943 high school students (48% female) ranging from 14 to 19 years
of age (62% identifying as white, 18% Hispanic, 13% African American, and 7% in other categories). Results showed that both
male and female students in schools with positive climates reported lower levels of personal substance use. Drug testing was
associated with lower levels of personal substance use in positive school climates, but only for female students. There was
no relationship between drug testing and male students’ substance use. The results are discussed in terms of the importance
of considering school climates before implementing drug-testing programs in high schools. 相似文献

First, the clothing and shoes from 29 participants who had recently filled their vehicles with petrol were analysed for any traces of petrol. No traces of petrol were found on any of these items. Secondly, the clothing and shoes from 17 participants who had recently used a petrol-powered lawn mower were also analysed for petrol. Petrol was detected on two pairs of shoes from different participants. Components of petrol were detected on a set of clothing from a third participant, however, there were insufficient components present in this sample to confirm the presence of petrol. No traces of petrol were found on the items from the remaining 14 participants. Thirdly, the clothing from a forecourt attendant, a mechanic and a professional lawn mower were analysed at the end of a number of shifts. Petrol was detected on the upper and lower clothing from the forecourt attendant at the end of one shift. No petrol residues were found on the forecourt attendant after a second shift, or on the mechanic's clothing after two separate shifts or on the professional lawn mower's clothing after three separate shifts. These results can be used to assist the forensic analyst in assessing the chance of finding traces of petrol on clothing and shoes after the wearer has performed common activities that involve petrol. 相似文献

Eighty years ago, Edwin H. Sutherland conceptualized and defined white‐collar crime. In this article, I engage retrospectively with Sutherland's ideas and work to emphasize important aspects that continue to guide research today; to note where he was prescient as well as shortsighted. I center this discussion around “corporate crime” or crimes by business. Four main themes are discussed: 1) law and official responses to corporate offending—the data problem, 2) corporate crime and the life cycle of organizations, 3) psychological and trait‐based explanations, and 4) consequences of definitional ambiguity. 相似文献

Reaching a postmortem diagnosis of hypothermia is challenging in forensic practice. Therefore, this study was conducted to detect the histopathological, histochemical and biochemical changes that occur in adult albino rats following exposure to induced fatal hypothermia. Twenty-four adult albino rats were divided into the negative control, moderate hypothermia, severe hypothermia and hypoxia groups. Rats in the control group were euthanized when those in the moderate hypothermic group died. Blood samples were collected via heart puncture, and the cerebrum, heart, suprarenal gland, kidney, liver and skeletal muscle were removed to investigate the biochemical, histochemical and histopathological changes. Postmortem assessment depicted significant changes in lipid peroxidation, represented by increased malondialdehyde levels in the studied organs of the rats in hypothermic and hypoxia groups. Histopathological examination of the rats’ organs revealed degeneration and necrosis in the hypothermia and hypoxia groups. Sections taken from the severe hypothermic rats revealed a loss of normal cardiac tissue architecture, necrotic changes in the pyramidal cells in the cerebral cortex, and massive necrosis, mainly in the tubules of the renal cortex and medulla. These findings suggest that histological changes might be used as biochemical markers for postmortem diagnosing of fatal hypothermia, particularly in severe hypothermic conditions.
Key points
- Death by hypothermia is a serious public health problem worldwide.
- Confirming a diagnosis and determining the cause of death in cases of hypothermia are among the most difficult practices in forensic medicine.
- Death by hypothermia might be associated with structural abnormalities in various organs.
- Studies using different tissue staining techniques will enable an overall illustration of the role of histopathological changes in body organs as indicators of hypothermia.

The right to request flexible working has been introduced into the UK employment laws against a background of post-fordist
work practices, which already allow for employer rather than employee flexibility. This paper posits the idea that for the
individual employee to benefit from these new rights what is required is the situation of dialogues within the workplace that
take place in an ethical frame that recognises the employee as an individual.
