Assessing program impact using latent growth modeling: a primer for the evaluator

Latent growth modeling (LGM) has emerged as a flexible analytic technique for modeling change over time because it can describe developmental processes at both the inter- and intra-individual levels. The LGM method can also provide a means for testing the contribution of other variables in order to explain variability in growth trajectories. This paper didactically illustrates the use of LGM as an analytical tool in program evaluation. Specifically, a hypothetical evaluation of a high school drug prevention program was used to demonstrate: (a) how LGM can be used to assess the longitudinal impact of a prevention program by comparing treatment and control populations with respect to individual differences in initial status and in rate of change; and (b) how predictors of initial status (post-intervention) and growth selected on the basis of a particular program theory can be incorporated in the model to explain program impact. Some advantages and limitations of using LGM in program evaluation are highlighted.     

Strike Lengths: Correcting for Prestrike Announcements and the Ratio of Bargaining Size to Firm Size

Anticipating the duration of a labor strike can be vital for both sides of the dispute, as well as outside observers. The methods of a pair of studies using Canadian data are surveyed to analyze labor strikes in the United States from 1992 to 2008. Corrections are made for strikes with predetermined lengths (“one-day” strikes and the like), whose durations are more a function of the prior announcements than of other factors, such as number of employees striking and macroeconomic conditions. Strikes are found to be generally shorter when the striking unit represents a larger portion of the firm’s total workers, a proxy for its bargaining power. This ratio provides a better understanding of the strike dynamics (including expected length) than do sheer bargaining unit size or sheer firm size.     

Conceptualising the psycho‐emotional aspects of disability and impairment: the distortion of personal and psychic boundaries

Recent feminist critics of the social model of disability have pointed towards a danger that disability studies may give relatively little attention to personal and emotional aspects of disablist oppression and impairment. We argue for consideration of the centrality of the distortion of personal and psychic boundaries as a key aspect of oppressive relational dynamics surrounding disability. Within the observer the disturbing psychic evocations of disability, and related defences, are connected to the maintenance of dynamics of unreal, collusory and alienating modes of relating, which may deprive disabled people of the recognition of subjective experience and personhood. Skewed socialisation of disabled people, involving inter alia the protection of the emotional lives of others, as well as the reality of inaccessible material resources, contributes to the internalisation of disablism and the ideological recruitment of disabled people as complicit in their marginalisation.     

The Effect of Risk Beliefs on Property Values: A Case Study of a Hazardous Waste Site1

Health risk beliefs of homeowners near a landfill site were assessed in a survey and compared to expert judgments of the health risks of living near the site. A bimodal distribution of health risk beliefs suggested sharp disagreement between the experts and at least some of the residents. Correlates of high risk beliefs included perception of odor from the site, exposure to media coverage of the problem, having children living at home, age (younger respondents more concerned), and gender (females more concerned). An aggregated neighborhood health risk belief predicted reductions in home prices even after controlling for home physical characteristics, such as size and other disamenities such as proximity to a freeway. In the 4100 homes near the site, the estimated depression in property values was estimated to total about $40.2 million before the site was closed and to be about $19.7 million after closure. Implications of these results for community conflict and for benefit-cost analysis of hazard site remediation are discussed.     

Levels of analysis,theoretical orientations and degrees of abstraction

This article suggests that what often appear to be fundamental conflicts of opinion among sociologists regarding appropriate levels of analysis and theoretical orientations are much less problematic when considered in terms of differences in degrees of abstraction. The critical factor in the compatibility of various levels of analysis and theoretical orientation is the use of degrees of abstraction by the researcher. The impact of this issue on sociological knowledge and some of its applications are examined.

Who Cares If Police Become Violent? Explaining Approval of Police Use of Force Using a National Sample

Understanding police violence is important in part because police violence, if generally tolerated, could transform a society based on law into one governed by political and personal whim. This research asks whether the conflict perspective can explain which groups are more likely to approve of police use of force, and whether several dimensions of power are at issue or just a few. Previous studies have found that race is the most important factor in determining approval of police use of force. Gender, age, class, and other variables have shown mixed results. Using a national sample (1998 General Social Survey), this paper contributes a more comprehensive examination of this issue to the small body of literature in this area. We look at approval of police use of force in five scenarios. Our findings show that minorities and women are more likely to disapprove of police use of force. Supporting a narrow application of conflict theory, other dimensions of power appear not to affect attitudes toward police hitting citizens. Context of violence matters too. When situations are not actively threatening for officers, by near consensus, violence is unacceptable. Disagreement comes from less clear-cut circumstances.
