This study investigated hope as a protective factor buffering the relationships between parenting stress and well-being among a sample of parents identified at moderate to high risk for child maltreatment. Two hundred parents were recruited from a nonprofit organization providing secondary and tertiary child maltreatment prevention programs. Results of the analyses showed that parental stress was negatively associated with subjective and emotional well-being. Hope was positively correlated with well-being and negatively associated with parenting stress. Hierarchical regression analyses showed that hope had a significant incremental relationship to well-being and that the negative effects of parenting stress fell below statistical significance. These findings provide preliminary support for hope as a coping resource social workers can target when working with parents in the prevention of child maltreatment.  相似文献

Historically the law regarded children as inherently unreliable and made it difficult for them to testify. Since 1975 awareness of child abuse has increased and research has established that children can be reliable witnesses. Governments began to recognize the needs and capacities of children and enacted legal reforms to facilitate prosecutions for child abuse. This paper reports on a survey of victim witness workers and other justice system professionals which reveals some of the continuedfailings of that system in dealing with children. Althoughrelatively rare, there are cases of false allegations of abuse, usually a result of investigations by poorly trained professionals. Further legal reforms and better human supports are required to ensure that the needs of children are met and their capacities as witnesses are fully appreciated.  相似文献

Objectives: Older lesbian, gay, bisexual, and transgender (LGBT) adults are a vulnerable yet resilient population who face unique stressors as they foresee health decline. This paper presents the results of a study about community-dwelling LGBT older adults’ anticipated needs and fears related to nursing homes and assisted living. Methods: This qualitative study collected data through seven focus groups. The sample (= 50) consisted of LGBT-identified adults age 55 and over. We used an inductive, thematic analysis approach to data analysis. Results: Participants seek an inclusive environment where they will be safe and feel connected to a community. They fear dependence on healthcare providers, dementia, mistreatment, and isolation. Importantly, these fears can lead to identity concealment and psychological distress, including suicide ideation. Discussion: This study adds to the existing literature about the worries of older LGBT adults as they anticipate long-term care. The results suggest that older LGBT adults seek LGBT-inclusive residential care settings that encompass two distinct yet related aspects of LGBT-affirmative care: the procedural (e.g. culturally competent skills and knowledge of practitioners) and the implicit (e.g. the values and mission of the organization). This paper identifies implications for practice, policy, and training.  相似文献

The impact of R&D on growth through spillovers has been a major topic of economic research over the last thirty years. A central problem in the literature is that firm performance is affected by two countervailing “spillovers” : a positive effect from technology (knowledge) spillovers and a negative business stealing effects from product market rivals. We develop a general framework incorporating these two types of spillovers and implement this model using measures of a firm's position in technology space and productmarket space. Using panel data on U.S. firms, we show that technology spillovers quantitatively dominate, so that the gross social returns to R&D are at least twice as high as the private returns. We identify the causal effect of R&D spillovers by using changes in federal and state tax incentives for R&D. We also find that smaller firms generate lower social returns to R&D because they operate more in technological niches. Finally, we detail the desirable properties of an ideal spillover measure and how existing approaches, including our new Mahalanobis measure, compare to these criteria.  相似文献

Wildfire is a persistent and growing threat across much of the western United States. Understanding how people living in fire‐prone areas perceive this threat is essential to the design of effective risk management policies. Drawing on the social amplification of risk framework, we develop a conceptual model of wildfire risk perceptions that incorporates the social processes that likely shape how individuals in fire‐prone areas come to understand this risk, highlighting the role of information sources and social interactions. We classify information sources as expert or nonexpert, and group social interactions according to two dimensions: formal versus informal, and generic versus fire‐specific. Using survey data from two Colorado counties, we empirically examine how information sources and social interactions relate to the perceived probability and perceived consequences of a wildfire. Our results suggest that social amplification processes play a role in shaping how individuals in this area perceive wildfire risk. A key finding is that both “vertical” (i.e., expert information sources and formal social interactions) and “horizontal” (i.e., nonexpert information and informal interactions) interactions are associated with perceived risk of experiencing a wildfire. We also find evidence of perceived “risk interdependency”—that is, homeowners’ perceptions of risk are higher when vegetation on neighboring properties is perceived to be dense. Incorporating social amplification processes into community‐based wildfire education programs and evaluating these programs’ effectiveness constitutes an area for future inquiry.  相似文献

This study considers a typical scheduling environment that is influenced by the behavioral phenomenon of multitasking. Under multitasking, the processing of a selected job suffers from interruption by other jobs that are available but unfinished. This situation arises in a wide variety of applications; for example, administration, manufacturing, and process and project management. Several classical solution methods for scheduling problems no longer apply in the presence of multitasking. The solvability of any scheduling problem under multitasking is no easier than that of the corresponding classical problem. We develop optimal algorithms for some fundamental and practical single machine scheduling problems with multitasking. For other problems, we show that they are computationally intractable, even though in some cases the corresponding problem in classical scheduling is efficiently solvable. We also study the cost increase and value gained due to multitasking. This analysis informs companies about how much it would be worthwhile to invest in measures to reduce or encourage multitasking.  相似文献

The Collaborative Demonstration Program for Homeless Individuals is providing an opportunity for several community agencies in the United States to explore innovative intervention and treatment strategies to address the needs of homeless people with co-occurring (mental illness and substance abuse) disorders. This cooperative agreement, funded jointly by the Center for Mental Health Services (CMHS) and the Center for Substance Abuse Treatment (CSAT), is a $3 million project supporting programs in various community agencies to develop, document, and evaluate programs for persons who are homeless with co-occurring disorders to be used as models in other communities. The program models include: Assertive Community Treatment, Psychosocial Rehabilitation, Therapeutic Community, and an integrated treatment model. The first phase of the two-phase project funded 16 programs in the U.S. to develop manuals within their primary treatment modalities for homeless people with co-occurring disorders. For Phase II of the project, six of the 16 model programs were competitively selected to demonstrate program impact through formal program evaluation efforts. The data derived from the various projects will be compiled into a compendium of information for state agencies and community service providers throughout the U.S.  相似文献

In a majority rule voting game, the uncovered set is the set of alternatives each of which can defeat every other alternative in the space either directly or indirectly at one remove. Research has suggested that outcomes under most reasonable agenda processes (both sincere and sophisticated) will be confined to the uncovered set. Most research on the uncovered set has been done in the context of voting games with a finite number of alternatives and relatively little is known about the properties of the uncovered set in spatial voting games.We examine the geometry of the uncovered set in spatial voting games and the geometry of two important subsets of the uncovered set, the Banks set and the Schattschneider set. In particular, we find both general upper and lower limits on the size of the uncovered set, and we give the exact bounds of the uncovered set for situations with three voters. For situations with three voters, we show that the Banks set is identical to the uncovered set.  相似文献

According to most standard socioeconomic indicators (for example employment, income and education), Indigenous Australians tend to have worse outcomes than their non-Indigenous counterparts. Most objective health indicators including life expectancy also tend to be worse. Traditionally, these two domains and associated objective indicators have been the focus of research, government policy and evaluation. There has been less research, however, on differences between Indigenous and non-Indigenous Australians in subjective measures of wellbeing. In this paper, I attempt to answer three related research questions on Indigenous wellbeing—What is the average level of emotional wellbeing and satisfaction with life for the Indigenous and non-Indigenous population of Australia? How do the differences between the two populations change once other characteristics have been controlled for? What are the factors associated with emotional wellbeing within the Indigenous population? With regards to the first two questions, Indigenous Australians are less likely to report frequent periods of happiness and more likely to report periods of extreme sadness than the non-Indigenous population. Surprisingly, given these results for emotional wellbeing, a major finding from the analysis was that Indigenous Australians were significantly more likely to report above-average satisfaction with their life. The main finding with regards to the third question is that using retrospective measures, those in remote areas report higher levels of happiness than those in non-remote areas. This is different to the results for socioeconomic status and objective measures of health found elsewhere and has important implications for government policy in Australia.  相似文献
