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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

Seventy-five clinicians who treat compulsive gamblers were surveyed. Each rated 89 clinical tasks and responsibilities for importance in the treatment of this population. Analysis of those items for which a plurality of clinicians rated the item as critical was chosen as the criteria of importance. A principal components analysis was conducted to determine the underlying structure of clinical perceptions of importance. An eight-dimensional model was found to describe perceptions in the most satisfactory way. The analysis revealed five major and three minor clusters of tasks and responsibilities. The major dimensions were labeled as (1) self-help/social support, (2) crisis interventions, (3) behavioral resources for change, (4) psychodynamics of treatment, and (5) crisis severity. The minor dimensions were (6) knowledge and training, (7) ethics and sensitivity to needs, and (8) confidentiality and regulations. A brief discussion of the implications are presented.This research was supported in part by a grant from the Massachusetts Department of Public Health. 相似文献

Definitions of conflict and the legitimation of resources: The case of environmental risk 总被引:3,自引:0,他引:3
This paper examines the social construction of conflict over environmental health and safety issues (i.e., environmental risk). Four explanations for such conflict are commonly offered in the environmental policy literature. We examine the interests served by each. We hypothesize that environmental policy professionals hold definitions of conflict consistent with the values and interests of the organizations for which they work and the professions of which they are members. These definitions enhance the legitimacy of the resources those groups possess in relative abundance. Data from a survey of risk professionals are generally consistent with these hypotheses. We conclude by generalizing beyond environmental conflict to identify ways in which disputes about the nature of a social problem or conflict are often at the same time struggles to determine the value of the resources available to social movements and their opponents.An earlier version of the paper was presented at the 1984 annual meeting of the American Sociological Association.

A graph representing the probabilistic dependences between genotypes of individuals in a pedigree is shown to be four-colourable. The consequences of this for computation of probabilities, using both exact and Markov chain Monte Carlo methods, is discussed. A four-colouring and triangulation of an inbred section of a pedigree of Red-Crowned Cranes is illustrated. 相似文献
