This paper provides further evidence to challenge the scepticism of successful interprofessional working. It is a story of a project to support families and children, more specifically, isolated mothers, and the use of continuous quality improvement and action research methodologies to engage a community and change service provision. Based on exploratory group work Stay and Play child development and learning sessions were set up for, and were well received by, parents. The project group worked initially with uncertainty and undefined needs; professionals involved eventually saw the benefit of changing their practice to meet local community needs.  相似文献

Darwin explained how species began. Today we may be witnessing the sixth great extinction. Conservationists rely on the so-called "red list" of most-threatened species, but the red list has been criticised as arbitrary, subjective and based on inadequate data. David Keith looks at the science and the statistics of the red list.  相似文献

Abstract While sociologists and the public at large are increasingly interested in the life conditions of animals, conceptual and empirical development of the topic is limited. This paper seeks to further develop the sociological research on attitudes toward animal well‐being. We build on insights from contemporary stratification theory to explain the nature of animal attitudes and their determinants. We also extend past work by examining a broader range of factors related to attitudes about animal well‐being, focusing on place, other social structural factors, and individuals' unique animal‐related experiences. Data are from a survey of over 4,000 Ohio residents conducted in 2002. We find that childhood experience has the greatest place‐based effect on attitudes. Other findings highlight the importance of social structural factors, suggesting support for the “underdog hypothesis.” Women, people experiencing economic hardship, those with less education, younger and middle aged people, and blacks tend to be more concerned with animal well‐being. Individualized, experiential variables are also important. Our results reflect the complexity of attitudes about animals and point to the need for greater sociological attention to factors left largely unexplored in previous studies, including childhood place‐based factors, economic hardship, and individuals' unique animal‐related experiences  相似文献

Objectives. This article analyzes competing explanations for variation in the relative size of contemporary police forces in larger U.S. cities. The featured explanation is conflict theory, which previously provided much evidence for a racial threat thesis but limited evidence that racial insurgency affected police mobilization in the 1960s and 1970s. Methods. The study sample consists of the 66 cities with a population of at least 250,000 in 2000. Aggregate data from the Bureau of Justice Statistics, Congressional Quarterly's America Votes, and the U.S. Census Bureau are combined with a content analysis using the Lexis‐Nexis regional news database to generate the data set. OLS regression modeling is applied to the analysis of this cross‐sectional data set. Results. This analysis shows that the size of contemporary police forces is substantially shaped not only by the legacy of the 1960–1970 wave of racial unrest in the United States, but also by reaction to racial disorders in the 1980s and 1990s and by the prevalence of racial minorities in the current population. Conclusions. Police departments' relative force size in 2000 is not only a result of incremental growth from the size attained by 1980, but also is dramatically shaped by whether the city experienced a race riot from 1980–2000 and, to a lesser extent, the size of the minority population and the violent crime rate. City wealth is a less robust indicator; and there is no evidence that either community ideology or the degree of uptake of community policing matters.  相似文献

This purpose of this study was to explore the moderating influence of gender on the relationship between child maltreatment and internalizing symptoms (e.g., affective and somatic problems) and externalizing behavior (e.g., rule breaking behavior and aggression) among children aged 7–12 years old. Using a longitudinal comparison group design and a sample of 300 youth of which 56% (n = 168) had substantiated cases of child maltreatment, results of a structural equation modeling revealed that internalizing symptoms exerted a mediating influence that was conditioned by gender. Only girls’ internalizing symptoms were found to mediate the link between child maltreatment and externalizing behavior while a direct relationship between maltreatment and externalizing behavior was found among boys. These findings provide evidence for gender differences in the pathways between being child maltreatment and maladaptive thoughts, feelings, and behaviors. Thus, adapting evidence-based strategies that target gender specific internalizing behaviors and externalizing behaviors among maltreated youth may significantly reduce the risk of short and long-term maladaptive behavior.  相似文献

Because random assignment to conditions is often neither possible nor desirable in longitudinal evaluations of mutual help organizations, the influence of self-selection effects must be assessed in order to accurately interpret outcome data. One approach to adjusting for self-selection effects is to control for covariates that predict outcome using statistical procedures such as analysis of covariance (ANCOVA), partial correlations, and hierarchical regression. This approach has considerable power, but is less useful when an evaluator is interested in directly modeling the process of entry into a program and incorporating information on the factors affecting self-selection into estimation of program effects. Two-stage sample selection models are designed to address such situations. These models rely on regression procedures in which program participation is modeled in an initial equation, which yields a sample selection correction factor. The correction factor is included with participation in a second equation that predicts outcome. This two-stage procedure allows the evaluator to interpret the observed effects of a professional service or a self-help group in the context of the magnitude and direction of selection effects. We compare and contrast the covariate control and sample selection models in a longitudinal study of the effects of participation in Alcoholics Anonymous on drinking behavior.  相似文献

This article investigates the ‘becoming’ of queer female punx in the contemporary hardcore scene in a regional Australian city. Twelve young women aged 20–30 years were interviewed about their experiences of queer identity. They emphasized their involvement in the music scene as a key catalyst for the development of a queer punk identity even though the local hardcore scene is male-dominated and homosocial. We find that these young female queer punx assert their identity through collectively summoning and synthesizing the counternormative resources of both queer and punk Do It Yourself (DIY) to configure the space of hardcore differently. Our findings confirm the durability of a playful, subversive punk ethos in constituting challenges to the normative.  相似文献

In previous country programmes, communications development work was divided into single-issue vertical projects. Each project developed its own materials and would then send it to an in-house materials development unit. This unit would, in turn, design the graphics and layout, supervise the printing, and organise the field-testing. The system was production oriented. The Country Programme in Uganda is now organised on a broad-based programme arrangement in which different issues are combined. New concepts are being introduced along with new ways of working in the field, and a wide range of people from many different sectors and types of organisations are required for the production of communications materials.Inevitably, this approach has considerable costs, particularly in terms of time and control on the final product. During the time of transition from the single-intervention vertical product approach to a broad multi-sector programme approach, different processes were used to develop communications material. This variation created an opportunity to compare processes within one context, hence this assessment. The overall purpose of the assessment was to determine if the costs incurred by each method were justified in terms of the value added, such as stakeholder acceptance, ownership and use by the field staff.  相似文献

Summary.  Systematic review and synthesis (meta-analysis) methods are now increasingly used in many areas of health care research. We investigate the potential usefulness of these methods for combining human and animal data in human health risk assessment of exposure to environmental chemicals. Currently, risk assessments are often based on narrative review and expert judgment, but systematic review and formal synthesis methods offer a more transparent and rigorous approach. The method is illustrated by using the example of trihalomethane exposure and its possible association with low birth weight. A systematic literature review identified 13 relevant studies (five epidemiological and eight toxicological). Study-specific dose–response slope estimates were obtained for each of the studies and synthesized by using Bayesian meta-analysis models. Sensitivity analyses of the results obtained to the assumptions made suggest that some assumptions are critical. It is concluded that systematic review methods should be used in the synthesis of evidence for environmental standard setting, that meta-analysis will often be a valuable approach in these contexts and that sensitivity analyses are an important component of the approach whether or not formal synthesis methods (such as systematic review and meta-analysis) are used.  相似文献
