The quality of life concept in sociology

An interdisciplinary concept, quality of life (QOL) has gained prominence in research in psychology, marketing, and several other disciplines. What is its status in sociology? Arising out of the social indicators“movement,” QOL has gained attention as both objective and subjective measures. Precursors of the concept figured in sociological research in the 1930s on level and plane of living. Now, it is recognized in one sociological encyclopedia, a textbook, and a few sociological monographs, but otherwise has gained little coinage in general sociology. One social problems text has adopted it as an organizing theme. With these modest inroads, the components of QOL, such as inequality, income, crime, the environment, etc., always have been prominent in sociology. When QOL is recognized in theory and when legislatures require its use in evaluation of public programs, the concept will become established in sociological research.     

Pathways from physical childhood abuse to partner violence in young adulthood

Analyses investigated several competing hypotheses about developmental pathways from childhood physical abuse and early aggression to intimate partner violence (IPV) for young adult males and females at age 24. Potential intervening variables included: adolescent violence (age 15 to 18), negative emotionality at age 21, and quality of one's relationship with an intimate partner at age 24. At the bivariate level, nearly all variables were associated in the expected directions. However, tests of possible intervening variables revealed only a few significant results. For males, a strong direct effect of abuse on later partner violence was maintained in each model. For females, the quality of one's relationship with an intimate partner did appear to mediate the effect of childhood abuse on later violence to a partner, raising the possibility of gender differences in developmental pathways linking abuse to IPV. Implications with regard to prevention are discussed.     

Space city revisited: patterns of legal outcomes in Houston homicide

This study re-examines, and updates, that of Lundsgaarde (1977), who found that among homicide offenders in Houston, Texas, in 1969, less than 50% of those who killed intimates or other family members were ever prosecuted for their lethal acts. The general pattern that emerges from our analysis of a random sample of 428 homicide cases during 1985 to 1994 indicates that killers of intimate partners or relatives are somewhat more likely to be prosecuted as offenders who were friends or strangers to their victims. Also during this 1985 to 1994 time period, the relative percent of defendants who were sentenced to a prison term of 20 years of less was smallest for those who killed intimate partners or other family members compared to those convicted of killing friends/acquaintances or strangers. As for sex-specific legal dispositions in cases of lethal violence against intimates or other relatives, we found that sanctions against women were considerably less severe than those against male offenders, in both time periods.     

Comparing the New Zealand and Swedish National Surveys of Gambling and Problem Gambling

National surveys of gambling and problem gambling have recently been completed in New Zealand and Sweden. These studies are unique in that data collection was undertaken by official government statistical agencies, involved large, nationally representative samples, and attained high response rates. Comparison of the findings is facilitated by the use of similar procedures and instrumentation and is of interest in that both countries have similar per capita gambling expenditure and welfare states that have recently undergone major economic and social restructuring. Data on gambling participation, problem gambling prevalence and risk factors for problem gambling are presented and discussed. While there are a number of similarities and differences, the Swedish findings are more similar to those of an earlier national survey conducted in New Zealand during 1991. This suggests that risk factors are changing over time in relation to evolving patterns of gambling participation and attitudes towards gambling, a finding that has implications for future patterns of gambling and problem gambling in these and other countries.     

Measuring risk and protection in communities using the Communities That Care Youth Survey

The Communities That Care Youth Survey measures risk and protective factors shown in prior studies to predict adolescent problem behaviors such as drug use, delinquency, and violence. This paper describes the development and validation of cut points for the risk and protective factor scales in the Communities That Care Youth Survey that distinguish youths at higher risk for involvement in problem behaviors from those at lower risk. Using these cut points, populations surveyed with this instrument can be described in terms of the proportions of youths experiencing risk and the proportions experiencing protection on each predictor. This facilitates communities' prioritization of specific factors for attention. This paper compares different cut points, and evaluates the discriminant validity of selected cut points. Results indicate that cut points with sufficient sensitivity and selectivity can be established for each of the scales, and that risk and protective factors can be profiled as prevalence rates. Implications of these findings for prevention planning are discussed.     

Exposure Assessment Approaches for Engineered Nanomaterials

Products based on nanotechnology are rapidly emerging in the marketplace, sometimes with little notice to consumers of their nanotechnology pedigree. This wide variety of nanotechnology products will result (in some cases) in unintentional human exposure to purposely engineered nanoscale materials via the dermal, inhalation, ingestion, and ocular pathways. Occupational, consumer, and environmental exposure to the nanomaterials should be characterized during the entire product lifecycle—manufacture, use, and disposal. Monitoring the fate and transport of engineered nanomaterials is complicated by the lack of detection techniques and the lack of a defined set of standardized metrics to be consistently measured. New exposure metrics may be required for engineered nanomaterials, but progress is possible by building on existing tools. An exposure metric matrix could organize existing data by relating likely exposure pathways (dermal, inhalation, ocular, ingestion) with existing measurements of important characteristics of nanoscale materials (particle number, mass, size distribution, charge). Nanomaterial characteristics not commonly measured, but shown to initiate a biological response during toxicity testing, signal a need for further research, such as the pressing need to develop monitoring devices capable of measuring those aspects of engineered nanomaterials that result in biological responses in humans. Modeling the behavior of nanoparticles may require new types of exposure models that individually track particles through the environment while keeping track of the particle shape, surface area, and other surface characteristics as the nanoparticles are transformed or become reactive. Lifecycle analysis could also be used to develop conceptual models of exposure from engineered nanomaterials.     

Assessing the effects of a school-based intervention on unscheduled school transfers during elementary school.

Raising Healthy Children is a cluster-randomized study of a school-based intervention aimed at preventing problem behaviors among children recruited into the project in the first or second grade of elementary school. Multilevel analysis was used to compare students in intervention and control schools with respect to whether they transferred out of their original schools. Students in intervention schools were less likely to transfer within the first 5 years of the project. A multilevel discrete-time survival model that included both time-varying and contextual variables revealed that the difference in hazard of transfer was greatest in the earlier years of the project.
