Concurrent detection of heroin, fentanyl, and xylazine in seven drug-related deaths reported from the Philadelphia Medical Examiner's Office

Recreational drugs, such as cocaine and heroin, are often adulterated with other pharmacological agents to either enhance or diminish the drug effects. Between April 21, 2006 and August 8, 2006, the Philadelphia Medical Examiner's Office detected xylazine (a veterinary sedative) and fentanyl (a synthetic opioid) in specimens taken from seven cases. Initial immunoassay screening was performed on urine and blood for fentanyl, opiate, cocaine, phencyclidine (PCP), and benzodiazepines. All tests reported positive were confirmed by gas chromatography-mass spectrometry. All seven xylazine positive cases tested positive for fentanyl and six cases tested positive for 6-acetylmorphine (a metabolite and definitive marker for heroin). The seventh case was positive for morphine and had a history of heroin abuse. Xylazine was present in urine in all seven cases and blood levels were detected in three cases. The blood concentrations ranged from trace to 130 ng/mL. Fentanyl was present in the blood and urine in each case and blood concentrations ranged from 4.7 to 47 ng/mL. Adulteration of illicit drugs has become an epidemic health concern for drug users. Healthcare professionals need to be aware of this issue, so the patients can be treated in an effective, timely manner.     

Outcome evaluation of a high-intensity inpatient sex offender treatment program

The treatment outcome of a high-intensity inpatient sex offender treatment program was evaluated by comparing the sexual recidivism rates of 472 treated and 282 untreated sex offenders. The program is designed for moderate- to high-risk sex offenders and follows the principles of effective correctional treatment. The current investigation is an extension of an earlier study (Nicholaichuk et al., 2000) with the addition of 176 participants, an extra 4 years follow-up, and the use of Cox regression survival analysis to control for three potentially confounding variables: age of release, sexual offending history, and length of follow-up. Treated offenders sexually recidivated significantly less than the comparison group over nearly 20 years of follow-up, even after controlling for the aforementioned variables. The substantive findings suggest that treatment adhering to the what works principles can reduce long-term sexual recidivism for a moderate- to high-risk group of sex offenders.     

Identity Styles,Positive Youth Development,and Civic Engagement in Adolescence

Identity formation is a core developmental task of adolescence. Adolescents can rely on different social-cognitive styles to seek, process, and encode self-relevant information: information-oriented, normative, and diffuse-avoidant identity styles. The reliance on different styles might impact adolescents’ adjustment and their active involvement in the society. The purpose of this study was to examine whether adolescents with different identity styles report differences in positive youth development (analyzed with the Five Cs—Competence, Confidence, Character, Connection, and Caring—model) and in various forms of civic engagement (i.e., involvement in school self-government activities, volunteering activities, youth political organizations, and youth non-political organizations). The participants were 1,633 (54.1 % female) 14–19 years old adolescents (M _age  = 16.56, SD _age  = 1.22). The findings indicated that adolescents with different identity styles differed significantly on all the Five Cs and on two (i.e., involvement in volunteering activities and in youth non-political organizations) forms of civic engagement. Briefly, adolescents with an information-oriented style reported high levels of both the Five Cs and civic engagement; participants with a normative style reported moderate to high scores on the Five Cs but low rates of civic engagement; diffuse-avoidant respondents scored low both on the Five Cs and on civic engagement. These findings suggest that the information-oriented style, contrary to the diffuse-avoidant one, has beneficial effects for both the individual and the community, while the normative style has quite beneficial effects for the individual but not for his/her community. Concluding, adolescents with different identity styles display meaningful differences in positive youth development and in rates of civic engagement.     

Psychosocial differences between occasional and regular adolescent users of Marijuana and Heroin

Data on marijuana and heroin use were obtained from 969 adolescents in Hong Kong, part of them being offenders. Very high drug use prevalence rates were found, which is due to the unique population studied. All but two of the heroin users were incarcerated youth. Drug use frequencies were highly associated with psychosocial variables such as sensation seeking, peer drug use, family drug use, susceptibility to peer pressure, perceived control to gain access to drugs, intention to try other substances, and perceived adverse consequences of drug use. Interactions were found indicating, for example, that regularly marijuana using girls and occasionally heroin using girls were characterized by higher levels of sensation seeking and susceptibility to peer pressure than their male counterparts. Polysubstance use was generally related to high levels of psychosocial vulnerability factors. The exclusive use of marijuana was associated with high susceptibility to peer pressure and with perceived control to gain access to drugs. The findings reflect a complex interplay of psychosocial variables with substance use in adolescents that, however, cannot be generalized beyond this particular sample in Hong Kong.Received Ph.D. in Clinical Psychology from the University of North Texas.

Effects of self-monitoring and perceived approval on delinquent behavior among Hong Kong adolescents

It has been established that perceived approval from relevant others is related to delinquent behavior. The aim of the present study was to investigate how this relationship was mediated by self- monitoring. Eight hundred twenty-eight students from Grade 7 to Grade 9 were asked to respond to a questionnaire that measured their self-monitoring, the frequency they committed delinquent acts, and the perceived approval of committing these acts from their parents, teachers, and friends. Regression analyses indicated that self- monitoring wax an interacting factor between perceived approval and delinquency. On further path analyses, it was found that self- monitoring acted as a mediating factor, and that the relationship between delinquent behavior and perceived approval was more apparent among high self- monitoring individuals. The present study was based on data collected in the delinquency project by S. Lau and Kwok Leung.Received M.Phil. from University of Hong Kong and M.A. in education from Chinese University of Hong Kong. Research interests include self-monitoring, problem solving, and learning environments.Received Ph.D. from Purdue University. Research interests include values, self-concept, family processes, and the psychology of adolescence.     

Predictors of Asian American Adolescents’ Suicide Attempts: A Latent Class Regression Analysis

Although suicide-related outcomes among Asian American adolescents are a serious public health problem in the United States, research in this area has been relatively sparse. To address this gap in the empirical literature, this study examined subgroups of Asian American adolescents for whom family, school, and peer relationships exerted differential effects on suicide attempts. Data were drawn from Waves 1 and 2 of the National Longitudinal Study of Adolescent Health dataset and included responses from a national sample of 959 Asian American adolescents (48.0% girls; average age at Wave 2 = 16.43). A latent class regression was used to assess the optimal number of latent classes (i.e., subgroups of participants) that explained the associations between family, school, and peer relationships and subsequent suicide attempts. Three latent classes were identified. Most participants belonged to a latent class in which family, school, and peer relationships were protective factors. However, stronger school relationships and peer relationships were found to be risk factors in two other latent classes. The three latent classes also differed significantly in terms of suicide attempts, gender, and acculturation. The practical implications of this study, particularly for educators and mental health professionals, are discussed.     

Towards a More Comprehensive Analysis of Warlord Politics: Constitutive Agency,Patron–Client Networks and Robust Action

This article serves as a critique of a recent American foreign policy formulation proposing to eradicate ‘warlordism’ and asserting that democratic institutions can be directly created out of the post-eradication anarchic chaos. Against this background, recent years have indeed seen a bourgeoning literature on ‘warlord politics’ in Southeast Asia. The majority commonly portray political actors as faithful followers of economic rationality and self-interest. Therefore, most are conceived as selfish predators who ruthlessly use violence for private gains at the expense of public interest. By suggesting that comparative studies on warlordism have been heavily influenced by the political economy perspective, the article develops a more comprehensive analysis of warlord politics. Along the lines of patron–client network analysis, insights from moral economy and agency-structure sociological dualism are considered. Contrasting case studies are used to illustrate how the alleged warlords of Southeast Asia do not fit entirely into the political economy perspective. Caught in a vast patron–client network of competing interests and diverse powers across state and society, one's agency is constantly constituted by discursive arrays of contending interests, juxtaposing rationalities and multiple intentions. In state building, this complication is regarded as paradoxically necessary for compelling the alleged warlord-actor to re-define and elevate multiple private interests into public interest.
