According to bystander theory, factors such as the community environment, collective efficacy, and history of adverse childhood experiences could be related to likelihood of reporting or intervening against maltreatment. An online survey was conducted with 946 general population Californians obtained through mixed-mode random probability and quota-based recruitment methods. Using an experimental vignette design, participants were randomly assigned to two scenarios: a) potential child abuse occurring in their neighborhood; b) potential child abuse in an unfamiliar neighborhood. Weighted multivariate logistic regression models assessed relationships between the vignette condition, collective efficacy, appraisal of the behavior, and likelihood of reporting or intervening. The results suggested that perceiving the vignette as occurring in your own neighborhood was associated with lower odds of viewing the behavior as appropriate and considering it abusive. Higher collective efficacy scores were associated with lower odds of viewing the incident as inappropriate but higher odds of personally intervening. Adverse childhood experiences were positively related to reporting the incident to child protective services and intervening. Bystanders may be more likely to give parents in their own neighborhood "the benefit of the doubt" by viewing their abusive behaviors as less severe, potentially leading to underreporting. Neighborhood collective efficacy might increase willingness to personally intervene, but not contact systems such as child protective services or police, suggesting that enhanced trust in communities does not extend to these institutions. Our findings have implications for neighborhood and education interventions to enhance understanding of and willingness to intervene on behalf of children.  相似文献

ABSTRACT

Libraries worldwide have had to re-think their purpose and adapt to changing community needs and expectations. They are no longer simply repositories for old books. Rather, they are vital components of a community’s social and economic infrastructure that connects communities and fosters creativity and innovation. This paper explores the changing role of libraries—and public value organizations more broadly—in creating positive social, economic, and environmental outcomes for individuals and communities.  相似文献

This article is the fourth in a series on New Directions. The National Health Service is under pressure, challenged to meet the needs of an ageing population, whilst striving to improve standards and ensure decision making is underpinned by evidence. Health Education England is steering a new course for NHS library and knowledge services in England to ensure access to knowledge and evidence for all decision makers. Knowledge for Healthcare calls for service transformation, role redesign, greater coordination and collaboration. To meet user expectations, health libraries must achieve sustainable, affordable access to digital content. Traditional tasks will progressively become mechanised. Alongside supporting learners, NHS librarians and knowledge specialists will take a greater role as knowledge brokers, delivering business critical services. They will support the NHS workforce to signpost patients and the public to high‐quality information. There is a need for greater efficiency and effectiveness through greater co‐operation and service mergers. Evaluation of service quality will focus more on outcomes, less on counting. These changes require an agile workforce, fit for the future. There is a bright future in which librarians’ expertise is used to mobilise evidence, manage and share knowledge, support patients, carers and families, optimise technology and social media and provide a keystone for improved patient care and safety.  相似文献

In 1993, the U.S. Advisory Board on Child Abuse and Neglect recommended a neighborhood-based strategy to prevent child abuse and neglect. The Board further recommended the development of Prevention Zones to allow for testing of the effectiveness of community-wide child protection efforts in neighborhoods of differing population density, ethnic and cultural composition, and social and economic resources. Following the Board's recommendation, this article presents the results of a trial of the effectiveness of a neighborhood-based strategy in low- and high-resource communities. Using management, survey, and administrative data, the research showed that both community types experienced declines in founded cases of and injuries suggesting child maltreatment for children under age 5. Low-resource communities experienced greater levels of mobilization, as measured by community and institutional engagement, and a greater number of positive outcomes related to changes in the quality of life for families and community norms relative to child and family well-being. In particular, the low-resource communities experienced the largest increases in receiving help from neighbors, neighboring, perceived household safety for neighborhood children, and observed positive parenting. High-resource communities experienced greater increases in intermediate outcomes related to self-reported parenting practices. The findings suggest that, ultimately, community mobilization can occur and be an effective means of preventing child maltreatment across community types. It appears, however, that community mobilization may play a more significant role in low-resource communities.  相似文献
