Psychological Control and Autonomy Granting: Opposite Ends of a Continuum or Distinct Constructs?

This article explores the relationship between parental psychological control and parental autonomy granting, and the relations between these constructs and indicators of adolescent psychosocial functioning, in a sample of 9,564 adolescents from grades 9 to 12. Participants completed a comprehensive parenting questionnaire as well as several measures of psychosocial adjustment. Confirmatory factor analyses of the parenting items revealed discrete factors for psychological control and autonomy granting, suggesting that these are distinct parenting constructs rather than opposite ends of a parental control continuum. Moreover, structural equation modeling showed that these factors were weakly correlated and differentially related to adolescent internalizing symptoms. Findings have implications for future conceptualization and measurement of psychological control and autonomy granting, and for research examining their effects on adolescent development.     

The Role of Migration Policy Changes in Europe for Return Migration to Senegal

This study questions the role of migration policy changes in France, Italy, and Spain for return migration to Senegal, by analyzing biographic data from the Migration between Africa and Europe (MAFE‐Senegal) survey and the contextual data of the Determinants of International Migration (DEMIG) VISA and DEMIG POLICY databases that cover major changes in migration policies in these destination countries for the different categories of migrants. Event history logistic regressions reveal that Senegalese migrants are less likely to return when the entry restrictions have become tighter. This result suggests that the decision to return depends on the possibility of migrating again after the return, which is crucial for both theory and policy regarding Western democracies' attempts to regulate migration.     

Evaluation of objectivity, reliability and criterion validity of the key indicator method for manual handling operations (KIM-MHO), draft 2007

Upper extremity musculoskeletal symptoms and disorders are common in the working population. The economic and social impact of such disorders is considerable. Long-time, dynamic repetitive exposure of the hand-arm system during manual handling operations (MHO) alone or in combination with static and postural effort are recognised as causes of musculoskeletal symptoms and disorders. The assessment of these manual work tasks is crucial to estimate health risks of exposed employees. For these work tasks, a new method for the assessment of the working conditions was developed and a validation study was performed. The results suggest satisfying criterion validity and moderate objectivity of the KIM-MHO draft 2007. The method was modified and evaluated again. It is planned to release a new version of KIM-MHO in spring 2012.     

Reconfiguring Sovereignty in Foucauldian Genealogies of Power: The Case of English Master and Servant Law and the Dispersion and the Exercise of Sovereignty in the Modern Age

This paper is a critique and partial reconfiguration of the Foucauldian genealogy of sovereignty. Sovereignty is largely conceptualized as the antithesis of governmentality and disciplinary power in the modern age; presented as a negative case as a juridical and centralized power of interdiction and containment in the classical age. I argue that we can genealogically examine how sovereignty in the modern age underwent transformation and dispersion. My empirical focus is on how master and servant law in the eighteenth and nineteenth centuries, along with the development and transformations of local courts, led to the increasingly dispersal of sovereign power as it as practiced in specific industrial sites and regions.     

The Development of Impulse Control and Sensation‐Seeking in Adolescence: Independent or Interdependent Processes?

This study examines whether changes in impulse control and sensation‐seeking across adolescence and early adulthood reflect independent or interdependent developmental processes. Data are drawn from a national longitudinal study (N = 8,270; 49% female; 33% Black, 22% Hispanic, 45% non‐Black, non‐Hispanic). An autoregressive latent trajectory model is used to test whether development in one trait influences development in the other. Although levels of these traits are inversely correlated, we do not find evidence that change over time in either trait is influenced by the prior level of the other. This failure to reject the null hypothesis is consistent with the view that sensation‐seeking and impulse control are the products of distinct neuropsychological systems that develop independently of one another.     

Methods to assess measurement error in questionnaires of sedentary behavior

Sedentary behavior has already been associated with mortality, cardiovascular disease, and cancer. Questionnaires are an affordable tool for measuring sedentary behavior in large epidemiological studies. Here, we introduce and evaluate two statistical methods for quantifying measurement error in questionnaires. Accurate estimates are needed for assessing questionnaire quality. The two methods would be applied to validation studies that measure a sedentary behavior by both questionnaire and accelerometer on multiple days. The first method fits a reduced model by assuming the accelerometer is without error, while the second method fits a more complete model that allows both measures to have error. Because accelerometers tend to be highly accurate, we show that ignoring the accelerometer's measurement error, can result in more accurate estimates of measurement error in some scenarios. In this article, we derive asymptotic approximations for the mean-squared error of the estimated parameters from both methods, evaluate their dependence on study design and behavior characteristics, and offer an R package so investigators can make an informed choice between the two methods. We demonstrate the difference between the two methods in a recent validation study comparing previous day recalls to an accelerometer-based ActivPal.
