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.

“Racial Threat”, Partisan Climate, and Direct Democracy: Contextual Effects in Three California Initiatives

Does context—racial, economic, fiscal, and political—affect whites’ votes on racially-related ballot propositions? We examine non-Hispanic whites’ voting behavior on three California ballot initiatives: Propositions 187, 209, and 227. Unlike previous analyses that lacked individual-level data and were therefore limited to ecological inference, we combine individual-level data from exit polls with county-level contextual variables in a hierarchical linear model. Racial/ethnic context affected whites’ votes only on Proposition 187, economic context had no influence on vote choice, and the effect of fiscal context was limited to Proposition 227. However, across the propositions, whites’ decisions were shaped by their political context. Thus, we do not find support for the “racial threat” hypothesis across all racially-charged issues.     

Hong Kong's policy possibilities and directions toward the mainland‐Taiwan conflict

On 1 July 1997, Hong Kong was returned from British colonial rule to Chinese rule under the sovereignty of the People's Republic of China (PRC). The change in political status of Hong Kong has great impacts on the triangular relationship between Hong Kong, the mainland and Taiwan, in which the mainland and Taiwan are still in a state of intense political conflict and competition. This paper examines the policy possibilities and directions for Hong Kong as a Special Administrative Region of the PRC in handling its relations with Taiwan. It argues that both Beijing and Taipei want to preserve the existing Hong Kong‐Taiwan relations for political and practical purposes but at the same time will try to avoid being forced into a suspected political trap—for Beijing the recognition of Taiwan as an independent political entity and for Taipei the subordination of Taiwan to PRC sovereignty. Between these two baselines, the paper points out that Hong Kong should pursues its own Taiwan policy built upon the interests of Hong Kong and depoliticization of Hong Kong‐Taiwan relations.     

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.

Fatal Insulin Overdoses: Case Report and Update on Testing Methodology

Suicidal insulin overdoses are an under‐recognized and uncommon cause of death, often relying on scene and nonspecific autopsy findings. Here, we present a case report of a fatal exogenous insulin overdose in a patient with type 1 diabetes. In our case, there were no contributory autopsy findings; however, serum analog aspart insulin levels were c. 10× the predicted therapeutic upper limit (4000, reference 6.6–55 uU/mL), which correlated with scene findings. This was specifically determined by a newly developed immunocapture liquid chromatography–tandem mass spectrometry assay, able to discriminate between various synthetic insulin analogs. Total insulin levels by immunoassay were highly elevated on the Siemens Advia Centaur, but not the Roche platforms (4741 vs. 5.2 uU/mL, respectively), showing variable sensitivity of detection within the same analog depending on assay. We discuss the prevalence and features to look for at autopsy in these types of cases. Additionally, analytical options for testing insulin levels, including new methodologies, guidance on collection of samples, as well as an outline of available historical reference range data are discussed.     

A Framework for Unifying Formal and Empirical Analysis

An important disconnect exists between the current use of formal modeling and applied statistical analysis. In general, a lack of linkage between the two can produce statistically significant parameters of ambiguous origin that, in turn, fail to assist in falsifying theories and hypotheses. To address this scientific challenge, a framework for unification is proposed. Methodological unification leverages the mutually reinforcing properties of formal and applied statistical analysis to produce greater transparency in relating theory to test. This framework for methodological unification, or what has been referred to as the empirical implications of theoretical models (EITM), includes (1) connecting behavioral (formal) and applied statistical concepts, (2) developing behavioral (formal) and applied statistical analogues of these concepts, and (3) linking and evaluating the behavioral (formal) and applied statistical analogues. The elements of this EITM framework are illustrated with examples from voting behavior, macroeconomic policy and outcomes, and political turnout.     

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.
