A presumption to disclose: new laws on the provision of information about child sex offenders to parents in England and Wales

In England and Wales, agencies managing child sex offenders in the community have long had the power to disclose information on those offenders to other agencies and sometimes to individual members of the public; this process has variously been referred to as ‘discretionary disclosure’ or ‘controlled disclosure’. In 2008, new laws were passed to strengthen this process and allow designated members of the public to request such information and imposed a new duty on agencies considering disclosure to conduct those considerations with a ‘presumption to disclose’. This article looks at the background to the new laws and how they might work in practice. Copyright © 2010 John Wiley & Sons, Ltd.     

Stuck in the Middle: Maintaining the Organizational Legitimacy of the Regional Environmental Center

Maintenance of legitimacy is central to the survival of any organization and is of particular importance to non-governmental organizations (NGO) reliant on external sources of income. Interaction with the external environment plays an important role in determining organizational legitimacy, shaping actions and determining opportunities. The ability of an organization to effectively respond to and influence the external environment can potentially strengthen its legitimacy. This paper considers the issue of organizational legitimacy by using resource dependence and institutional theories to analyze the development of the Regional Environmental Center for Central and Eastern Europe (REC). The findings indicate that it is possible for an organization to maintain legitimacy through adaptation, responding to the rise and fall of external opportunities and challenges. As predicted by institutional theory, it also argues that external environmental factors place increasing pressure for conformity over time, limiting scope to manoeuvre over the longer-term.     

Cycles versus equilibrium in evolutionary games

Mixed-strategy equilibria are typically rather unstable in evolutionary game theory. “Monocyclic” games, such as Rock–Paper–Scissors, have only mixed equilibria, some of which are “stable” in the sense that sequential best replies lead to them; yet, even these games are prone to stable cycles under discrete-time simultaneous best replies, giving an unusual equilibrium-selection problem. This article analyzes such games in a random-utility setting where changing strategies is costly, and the speed of the dynamic is, thus, endogenous. The stochastically stable outcome is determined by the cost of switching strategies; when switching costs are high, mixed equilibria are selected, whereas when switching costs are low, cycles are selected.     

Predictors of Longitudinal Growth in Inhibitory Control in Early Childhood

In the current study, we examined latent growth in 731 young children's inhibitory control from the ages of two to four years, and whether demographic characteristics or parenting behaviors were related to initial levels and growth in inhibitory control. As part of an ongoing longitudinal evaluation of the family check‐up, children's inhibitory control was assessed yearly at the ages of two to four years. Inhibitory control was initially low and increased linearly to the age of four years. High levels of harsh parenting and male gender were associated with low initial status in inhibitory control. High levels of parental positive behavior support were associated with faster growth. Extreme family poverty and African‐American ethnicity were also associated with slower growth. The results highlight parenting as a target for early interventions in contexts of high socioeconomic risk.     

Skin color,sex, and educational attainment in the post-civil rights era

We assess the relationship between skin color and educational attainment for native-born non-Hispanic Black and White men and women, using data from the Coronary Artery Risk Development in Young Adults (CARDIA) Study. CARDIA is a medical cohort study with twenty years of social background data and a continuous measure of skin color, recorded as the percent of light reflected off skin. For Black men and women, we find a one-standard-deviation increase in skin lightness to be associated with a quarter-year increase in educational attainment. For White women, we find an association approximately equal in magnitude to that found for Black respondents, and the pattern of significance across educational transitions suggests that skin color for White women is not simply a proxy for family background. For White men, any relationship between skin color and attainment is not robust and, analyses suggest, might primarily reflect differences in family background. Findings suggest that discrimination on the basis of skin color may be less specific to race than previously thought.     

Linking Changes in Parenting to Parent–Child Relationship Quality and Youth Self‐Control: The Strong African American Families Program

A randomized prevention trial was conducted contrasting families who took part in the Strong African American Families Program (SAAF), a preventive intervention for rural African American mothers and their 11‐year‐olds, with control families. SAAF is based on a conceptual model positing that changes in intervention‐targeted parenting behaviors would enhance responsive‐supportive parent–child relationships and youths' self‐control, which protect rural African American youths from substance use and early sexual activity. Parenting variables included involvement‐vigilance, racial socialization, communication about sex, and clear expectations for alcohol use. Structural equation modeling analyses indicated that intervention‐induced changes in parenting were linked with changes in responsive–supportive parent–child relationships and youth self‐control.     

A UNIFIED FRAMEWORK FOR MODELLING WILDLIFE POPULATION DYNAMICS†

This paper proposes a unified framework for defining and fitting stochastic, discrete‐time, discrete‐stage population dynamics models. The biological system is described by a state‐space model, where the true but unknown state of the population is modelled by a state process, and this is linked to survey data by an observation process. All sources of uncertainty in the inputs, including uncertainty about model specification, are readily incorporated. The paper shows how the state process can be represented as a generalization of the standard Leslie or Lefkovitch matrix. By dividing the state process into subprocesses, complex models can be constructed from manageable building blocks. The paper illustrates the approach with a model of the British grey seal metapopulation, using sequential importance sampling with kernel smoothing to fit the model.
