Bath salts are new designer drugs with stimulant effects on the central nervous system. White or brown powder sold online and in mini‐marts under different brand names, bath salts can be used by injecting, snorting, smoking, or ingesting with food or drink. The case of a 30‐year‐old Caucasian male who developed acute psychosis within a few hours of injecting himself with bath salts is described. The patient was hospitalized with a complaint of hearing voices. The drug also induced in the patient a state of euphoria, increased energy level, along with decreased need for sleep and decreased appetite. The psychological effects of the bath salts subsided within a few hours of injection and his reality testing remained consistently intact over the next 3 days of hospitalization. This case brings to attention the fact that bath salts were legal throughout the United States until recently and is still not completely controlled. This report informs clinicians of harmful effects of bath salts, including severe agitation with possible rhabdomyolysis, psychosis, suicidal ideation, hypertension, tachycardia, and death.  相似文献

The present study examines differences between homeless adolescents, young adults, and older adults served by homeless shelters or food programs to inform service provision. Four homeless studies using the same sampling and measurement methods were pooled to permit comparisons across age groups. Results showed that homeless adolescents demonstrated greater resilience than younger and older adults. Adolescents reported the shortest duration of homelessness, lowest number of life stressors, fewest physical symptoms, largest social networks, and fewest clinically significant mental health problems. Adolescents also received fewer alcohol and drug abuse diagnoses than younger and older adults. Younger adults reported less time homeless and fewer physical symptoms than older adults, but more life stressors. Younger adults also endorsed higher levels of hostile and paranoid psychological symptoms. Implications for service provision and policy are discussed.  相似文献

SUMMARY

Trends in substance abuse prevention have not adequately addressed the needs of girls and female adolescents. The precursors to substance use and abuse in adolescence are analyzed specifically from a gender-specific perspective. Female drug use as both a maladaptive and adaptive pattern of coping behavior is examined within a socio-cultural context. This new understanding points to the need for alternative models of prevention with particular attention to risk, resiliency and protective factors. The expanded role of the family therapist as “Family Life Cycle Specialist” within a prevention model will be highlighted.  相似文献

While the literature on peacekeeping has mostly focused on whether peacekeeping actually keeps the peace, few studies have systematically addressed the question of what explains variations in unintended consequences of peacekeeping, such as sexual exploitation and abuse (SEA). This study presents the Sexual Exploitation and Abuse by Peacekeepers data, a new dataset covering the 36 international peacekeeping missions by the UN, NATO, ECOWAS, and the African Union, active in the years 1999–2010. Using this dataset, it also presents the first statistical study that explores the issue of what can account for variations in reported SEA across peacekeeping operations. The systematic analysis of this data indicates that SEA was more frequently reported in situations with lower levels of battle-related deaths, in larger operations, in more recent operations, the less developed the country hosting the mission, and in operations where the conflict involved high levels of sexual violence. Our discussion and conclusion highlights data restrictions and identifies key challenges for future research.  相似文献

Despite the increase in the number of females incarcerated, there is a paucity of research concerning female life-sentenced inmates in the United States. Using a nationally representative data set containing the largest known sample of this population, the present research examines the pre-incarceration traumatic experiences of female life-sentenced inmates. The results indicate that these women are more likely to experience traumatic events, in particular abuse, than either male life-sentenced inmates or female inmates in general. Logistic regression analyses reveal a significant association between abuse and a life sentence in both gender-specific models.  相似文献

This research traces the history of Tracy Neal v. Michigan Department of Corrections, a class action lawsuit against the Michigan Department of Corrections that alleged the sexual abuse of women prisoners spanning more than two decades. The litigation resulted in combined jury verdicts of more than $30 million for the plaintiffs and a $100 million settlement that included extensive injunctive relief. This article examines the abuses and conditions suffered by female inmates in Michigan prisons, the court decisions, jury trials, and settlement. Drawing on interviews from several lead attorneys for the plaintiffs, the article provides an examination of the circumstances, discusses litigation strategy, and highlights lessons from Neal that could be relevant to civil rights scholars and advocates. The article concludes with a discussion of the impact and future implications of this case.  相似文献

美国有联邦监听法律法规,但各州也根据自己的立法权制定了一些本州的监听法。宪法虽然为美国人权、隐私权提供了有效的保护伞,但自9.11以后,《美国爱国者法案》赋予了美国总统特权,监听扩权问题甚嚣尘上。但联邦层面上对监听问题的监督相对完善,对此的介绍也频见报端,但对各州监听立法的研究却鲜有所见。文章比较详尽地介绍了美国各州的监听立法情况,披露了各州监听立法的内容、执法程序、监督机制等等都不尽如人意,权力监督不力、滥用情况比较普遍,以资我国监听立法借鉴。  相似文献

Parental substance abuse is a major factor in families experiencing foster care placement, yet little is known about the potential of screening in determining risk or identifying subpopulations for which elevated risk occurs. One Midwestern state recently implemented screening. This research uses information gathered as part of the screen's implementation to conduct a latent class analysis. The research was extended to provide a detailed examination of differences in child and family characteristics across classes, and to compare the screen results with caseworker impressions. Three distinct typologies emerged, with the high-risk and moderate-risk designations comprising only one quarter of the cases.  相似文献

Each year, a significant number of adolescents become pregnant in the United States, with more than half of these pregnancies resulting in live births. Adolescent parenting is associated with poor outcomes, including increased risk of child maltreatment. Youth “aging out” of the foster care system may be at greater risk of maltreating their children due to their experiences of child maltreatment, a lack of social support, and little preparation for parenthood. This article examines current programs and policies targeting pregnant and parenting youth aging out and presents a research agenda that focuses on pregnancy prevention and positive parenting.  相似文献

Research studies have found that for parents with children in foster care, use of problem-targeted services increases the likelihood of reunification. However, available research focuses almost entirely on substance abusing mothers, and rarely considers parents' use of parenting classes and counseling, services that are commonly ordered for most reunifying parents. This study examined the effects of parents' use of specific services on reunification. Findings suggest that in addition to parents' use of problem-targeted services, use or compliance with parenting classes and counseling services is also heavily weighted in reunification decision-making. Further research is needed to identify factors associated with service use and advance our understanding of the effectiveness of reunification services.  相似文献
