Epidemiology of completed suicides in Singapore for 2001 and 2002

This study provides an analysis of 640 completed suicide cases in Singapore for the years 2001 and 2002, compared to previous years and in relation to demographic and socioeconomic factors, as well as to the characteristics of a subgroup of suicide victims with prior psychiatric illness. There was little change in the suicide pattern over the 2 years studied compared to previous years. The sex ratio was constant at 1.5. Population-adjusted ratios were 1 for Chinese, 0.5 for Malays, and >1 for both Indians and other ethnic groups. Falling from heights ranked first in terms of method adopted for both years. A disproportionately higher number of suicides were recorded for the 25-34 and the > or =75-year-old age groups. A total of 47 (17.2%) in 2001 and 74 (20.2%) in 2002 of the cases had a history of prior psychiatric illness, with psychotic disorders being the most common diagnostic category. There was also a statistically significant correlation between unemployment and incidence rates. Although the overall rate of elderly suicides had gone down since the 1990s, prevention strategy should focus on the elderly as this rate is still about 3-4 times the national average.     

A Cross-National Comparison of the Internal Effects of Participation in Voluntary Organizations

This article draws on two recent and largely untapped sources of data to test empirically the Tocquevillian argument about the impact of involvement in civic organizations on individual attitudes and behaviors. Our analysis is based on two related studies – the European Social Survey (ESS) and the US 'Citizenship, Involvement, Democracy' (CID) survey – that incorporate innovative and detailed measures about respondents' involvement in voluntary associations in nineteen European countries and in the United States. These surveys provide us not only with rich individual-level data within a cross-national comparison, but they also allow us to develop and test a new measure of civic involvement that distinguishes between different levels of participation. After employing our 'civic involvement index' in pooled and individual country analyses, we find general support for the Tocquevillian argument. On average, those persons with greater levels of involvement in voluntary organizations also engage in more political acts, have higher life satisfaction and are by and large more trusting of others than those who do not. These findings highlight the general importance of actual involvement as opposed to nominal membership.     

Conduct Problems Among Children at Battered Women's Shelters: Prevalence and Stability of Maternal Reports

The present research was designed to (1) replicate prevalence estimates of clinical levels of conduct problems in a large (n = 401) sample of children residing at a shelter for battered women, and (2) assess the stability of mothers' reports of child conduct problems following shelter departure. According to mothers' reports on standardized questionnaires and diagnostic interviews obtained during shelter residence, approximately one third of the children between 4 and 10 years of age exhibited clinical levels of conduct problems. Prior research has demonstrated elevated maternal distress during shelter residence and suggests that such distress may influence mothers' reports of child conduct problems. To examine this issue, a subset of families with children exhibiting clinical levels of conduct problems (n = 68) was reassessed following their shelter departure. Mothers' reports of child conduct problems remained stable despite significant reductions in mothers' distress after shelter exit.     

Determination of ibogaine and noribogaine in biological fluids and hair by LC-MS/MS after Tabernanthe iboga abuse Iboga alkaloids distribution in a drowning death case

Tabernanthe iboga belongs to the Apocynaceae family. In this study, we report the case of a 37-year-old black male working as a security agent in Paris and found dead naked on the beach in Gabon after consumption of iboga. Autopsy revealed a drowning fatality and a myocardial abnormality (myocardial bridging). Samples of blood, urine, bile, gastric content, liver, lungs, vitreous, spleen and hair were taken. Biological fluids were liquid-liquid extracted with saturated NH4Cl pH 9.5 and methylene chloride/isopropanol (95/5, v/v) in presence of clonazepam-d(4), used as internal standard. After decontamination with dichloromethane, hair was cut into small pieces then sonicated for 2h in saturated NH4Cl pH 9.5 before extraction by methylene chloride/isopropanol (95/5, v/v). After evaporation the residues were reconstituted in methanol/ACN/formate buffer pH 3, from which 10 microL were injected into an ODB Uptisphere C(18) column (150 mm x 2.1mm, 5 microm) and eluted with a gradient of acetonitrile and formate buffer delivered at a flow rate of 200 microL/min. A Quantum Ultra triple-quadrupole mass spectrometer was used for analyses. Ionization was achieved using electrospray in the positive ionization mode (ESI). For each compound, detection was related to three daughter ions (ibogaine: m/z 311.4-->122.1, 174.1 and 188.1; noribogaine: m/z 297.4-->122.1, 159.1 and 160.1; clonazepam-d(4): m/z 319.9-->218.1, 245.1 and 274.1). Ibogaine and noribogaine were detected in all autopsy samples. Hair segmentation was not possible as hair was very short and frizzy. Concentrations of 1.2 and 2.5 ng/mg, respectively were detected. Neither other licit or illicit drugs nor alcohol were found. The presence of ibogaine and noribogaine in all autopsy samples was consistent with the recent absorption of Tabernanthe iboga, which was assumed to be responsible of the drowning fatality. The history of exposure, regarding hair analysis, is discussed. LC-MS/MS appears to be the best method for analyzing complex and poorly volatile alkaloids in autopsy samples and particularly in hair, due to the presence of a nitrogen ring and the relatively low concentrations to be measured.     

Assessing the investigative needs of rural law enforcement

Although the topic of rural crime has received relatively little attention in traditional criminal justice research, the more specialized subtopic of rural criminal investigation has received even less. As criminological research and public attention begin to focus upon rural crime due to its rapid growth, rural police agencies will need to assess their investigative attitudes and resources in an effort to reduce accelerating crime rates. This paper surveyed the attitudes of 52 rural sheriffs in an effort to gather information necessary to assess needs and attitudes unique to the rural investigation.     

Is Germany's xenophobia qualitatively different from everybody else's?

This paper grapples with a fundamental question that emerged repeatedly during the conference from which all of these papers are derived: is German antipathy to foreigners qualitatively different from that of other nations and ethnic groups? The paper provides an historical perspective on German immigration policy and on the recurrence of state-sanctioned killings from the witch hunts of the sixteenth and seventeenth centuries to the Holocaust. This paper concludes that there is evidence to support that xenophobia and hostility to ethnic minorities may be more dangerous in Germany than in other Western nations.     

Psychosocial Correlates of Affective Distress: Latent-Variable Models of Male and Female Adolescents in a Community Sample

Latent-variable confirmatory factor analysis was used to examine the interrelationships of depressive and anxious symptomatology and 13 measures of psychosocial functioning in a community-based sample of adolescents participating in a school-based drug abuse prevention intervention. Measures of psychosocial functioning included: cognitive self-efficacy, self-management, self-reinforcement, decision-making and problem-solving skills, interpersonal skills, social anxiety, behavioral style, risk taking, conventionality, somatic complaints, perceived tangible, and adult support. Simultaneous group comparison and nested hierarchical tests were used to statistically contrast parameters obtained from male and female models. Overall, the hypothetical constructs were statistically reliable and models were psychometrically sound. Partial factorial invariance was obtained, however, the patterns of covariation between distress and psychosocial functioning were dissimilar for male and female youth. Differences clustered around affective distress, cognitive skills, and perceived functional support. More socially anxious females perceived less social support, whereas support and anxiety were positively related among male students. Male youth with high levels of conventional behavior were also socially anxious, whereas for females this relationship was absent and nonsignificant. For both male and female students, distress was moderately and inversely related to cognitive efficacy and personal competence skills. Distressed youth were also less conventional (behavioral control) and less diligent, and were characterized by greater sensation-seeking, poorer competence, and perceived less social support, and were more socially anxious with less interpersonal skills. Findings are discussed in terms of potential contributors to gender differences in distress and psychosocial functioning and their implications for the understanding of adolescent mental health.     

Pathologic features of farm and tractor-related fatalities in children

A study of 15 childhood fatalities due to farm or tractor-related accidents demonstrated extensive injuries typified by crushing, evisceration, and amputation of limbs. Although these injuries are characteristic of industrial accidents in adults, such accidents do not commonly occur in children. However, the unique circumstance of the farm, which incorporates home and industrial environments, results in particularly severe patterns of injuries in accidental childhood deaths. A knowledge of the range of machines that are used and the environment of the farm facilitates assessment of the types of injuries that may be found at autopsy in cases of pediatric farm accident.
