Polydrug fatality involving metaxalone

A 29-year old female with a history of depression was found dead in a hotel room. The death scene investigation found empty pill bottles and an empty liter bottle of wine. Metaxalone, a centrally acting muscle relaxant, along with citalopram, ethanol, and chlorpheniramine were identified in the postmortem samples and quantitated by gas chromatography-mass spectrometry. The concentration of metaxalone in femoral vein blood was 39 mg/L. The heart blood concentration was 54 mg/L. Femoral vein blood concentrations of citalopram and chlorpheniramine were 0.77 mg/L and 0.04 mg/L, respectively. Ethanol levels were 0.13 g/dL in vitreous and 0.08 g/dL in heart blood. Other tissue samples were also analyzed. The authors consider the metaxalone concentrations toxic and potentially fatal. The citalopram concentrations were lower than those reported in fatal cases for this drug alone. Death was ascribed to polydrug abuse/overdose with metaxalone a major contributor. This represents the first reported case to our knowledge in which a metaxalone overdose significantly contributed to death.     

The fraction of disability caused at work

Disability has high societal and personal costs. Various disparate federal and state programs attempt to address the economic and social needs of people with disabilities. Presumably workplace injuries and accidents are an important source of disability. Yet separate public policies and research literatures have evolved for these two social problems--disability and workplace injuries--despite their relatedness. This article seeks to document the overlap between these two phenomena in estimating the proportion of the disabled population whose disability was caused by workplace injury, accident, or illness using the Health and Retirement Study of 1992. The results point toward the need for initiatives to reduce disability that focus on work-related causes, which are a common pathway to disability, and that may result in substantial savings in federal programs.     

Democratic Political Competence: Clearing the Underbrush and a Controversial Proposal

Though the link between democracy and an appropriately trained citizen is obvious, the theoretical and empirical nature of this association is murky despite mountains of scholarship addressing this topic. Part of this problem is that the term democratic competence has been stretched almost to the point of uselessness. This constant adding of desired traits—many of which are ideologically driven—misdirects effort away from such complex problems as the relationship between individual attributes and collective capacities. Moreover, recent research has often been guilty of using data of uncertain relevance to demonstrate a competence that seems largely an analytical artifact. We conclude by offering an approach that stresses old- fashioned traits such as patriotism that seem necessary to the existing, and quite democratic, status quo.     

Evaluating the Dimensionality and Invariance of ”Low Self-Control”

According to Gottfredson and Hirschi's (1990) A General Theory ofCrime, all illegal activity is the manifestation of a single underlyingcause. The authors argue that inadequate child-rearing causes individualsto develop a similar type of propensity for criminal and analogousbehavior. Gottfredson and Hirschi label this characteristiclow self-control. Six dimensions, which can be identified intheir theory, are suggested to comprise a final low self-controltrait. Further, low self-control is proposed to be an invariantcharacteristic (i.e., its form does not change with the age of theindividual or context in which the person resides). In this research, weevaluate these two propositions. First, the six dimensions are measured andused to determine if a multidimensional model can explain another commonfactor—low self-control—in two samples of individuals (fromdifferent locales) with dissimilar mean ages. Second, low self-control inboth samples is tested for invariance. We test the proposed invariance oflow self-control by examining if the parameter values in a model, which isreflective of Gottfredson and Hirschi's conceptualization of thecharacteristic, differ across the two samples of individuals. The resultssupport both of Gottfredson and Hirschi's propositions. Lowself-control does appear to be a multidimensional characteristic whosedimensions represent another common factor. Low self-control also appears tobe an invariant latent trait that members of these two samplespossess. These tests help to clarify Gottfredson and Hirschi'sconceptualization of low self-control.

Parental influences on the development of adolescent autonomy and identity

Two studies were undertaken to examine parental influences on autonomy and identity development. In Study 1, 262 adolescents in seventh and eleventh grades were given Kurtines's autonomy measure, Simmons's identity measure, and Elder's questions regarding the adolescents' perceptions of their parents' autocratic, democratic, or permissive parenting styles. Study 2 was a replication with 168 subjects. Across both studies it was found that sex-role socialization is more influential for automony development than is either level of parental power or age. Both age and father's use of democracy were the most influential variables on identity development.Received Ph.D. from the University of Minnesota.

Assessing Stability and Change in Criminal Offending: A Comparison of Random Effects, Semiparametric, and Fixed Effects Modeling Strategies

An important theoretical problem for criminologists is an explanation forthe robust positive correlation between prior and future criminaloffending. Nagin and Paternoster (1991) have suggested that the correlationcould be due to time-stable population differences in the underlyingproneness to commit crimes (population heterogeneity) and/or thecriminogenic effect that crime has on social bonds, conventionalattachments, and the like (state dependence). Because of data andmeasurement limitations, the disentangling of population heterogeneityand state dependence requires that researchers control for unmeasuredpersistent heterogeneity. Frequently, random effects probit models havebeen employed, which, while user-friendly, make a strong parametricassumption that the unobserved heterogeneity in the population follows anormal distribution. Although semiparametric alternatives to the randomeffects probit model have recently appeared in the literature to avoid thisproblem, in this paper we return to reconsider the fully parametric model. Viasimulation evidence, we first show that the random effects probit modelproduces biased estimates as the departure of heterogeneity from normalitybecomes more substantial. Using the 1958 Philadelphia cohort data, we thencompare the results from a random effects probit model with a semiparametricprobit model and a fixed effects logit model that makes no assumptions aboutthe distribution of unobserved heterogeneity. We found that with this dataset all three models converged on the same substantive result—evenafter controlling for unobserved persistent heterogeneity, with models thattreat the unobserved heterogeneity very differently, prior conduct had apronounced effect on subsequent offending. These results are inconsistentwith a model that attributes all of the positive correlation between priorand future offending to differences in criminal propensity. Sinceresearchers will often be completely blind with respect to the tenabilityof the normality assumption, we conclude that different estimationstrategies should be brought to bear on the data.     

Reforming rural Ontario

Abstract: This paper turns the scholarly spotlight onto an overlooked aspect of the Ontario municipal system by exploring the issue of county government reform in four selected communities in southern Ontario. Various proposals for county government reform have been advanced by the provincial government during the last quarter-century; here we consider the “common sense” approach to municipal government reform adopted by the Harris government after its election in 1995. We analyse how four counties have responded to this concerted and forceful attempt to bring about major county restructuring. The study has two major objectives. First, it illustrates the forces that have at once advanced and constrained county government reform in recent years; second, it attempts to explain major differences in the manner in which individual counties have responded to the Harris government's drive for reform. Finally, the paper concludes with some reflections on the viability of rural government in Ontario in the light of the substance and process of county government reform. Sommaire: Cet article examine un aspect négligé du système municipal ontarien en explorant la question de la réforme des gouvernements de comté dans quatre communautés choisies du sud de l'Ontario. Le gouvernement provincial a fait diverses propositions de réforme du gouvemement de comté au cours du demier quart de siècle; ici, nous examinons l'approche basée sur le « ban sens » adoptée par le gouvernement Harris en ce qui concerne les gouvernements municipaux, après son élection en 1995, et nous analysons la manière dont quatre comtés ont réagi à cette tentative concertée et vigoureuse de déclencher une forte restructuration au niveau du comté. Cette étude a deux grands objectifs. Premièrement, elle illustre les forces qui ont à la fois promu et retenu la réforme des gouvernements de comté au cours de ces dernières annèes; deuxièmement, elle essaie d'expliquer les principaux écarts dans la façon dont chaque comté a réagi aux efforts de réforme du gouvemement Harris. Enfin, I'article offer quelques réflexions sur la viabilité du gouvernement rural en Ontario à la lumière du fond et du processus de réforme des gouvernements de comté.
