Children who spend time in care are more likely to have an official record of offending behaviour than the general population. However, there is a lack of longitudinal research on the timing, severity, and volume of offending in relation to time spent in and out of care. Furthermore, differences in patterns of offending by identifiable groups in care are rarely a focus of research. This study is both longitudinal and identifies 8 groups within the care population with different volumes of recorded offending: ranging from a mean of 41.75 (prolific) to 1.60 (low). Substance misuse, gender, and reasons for referral to care were associated with different patterns of offending in and out of care. The study is primarily based on a subsample of 64 children who had offended whilst in care. The subsample represents 38.5% of a cohort of children who had been in care or were taken into care over a particular period (2008–2011) in one local authority. The placements and recorded offences of the 64 children were tracked for a further 2 years (2011–2013). The study highlights future areas of research and the need for more tailored responses to different groups within the care system.  相似文献

The worldwide aging of the population is having a major impact upon society. The United Nations General Assembly has declared 1999 to be the International Year of Older Persons to increase the awareness of aging worldwide. They identified five principles for older persons: independence, participation, care, self-fulfillment, and dignity. The numbers of elderly are growing around the world with many elderly living considerably longer than in past times. Developed countries are struggling with the high cost of maintaining support programs, and developing countries face dissolution of traditional care systems without institutional replacements. Women around the globe typically live longer than men, often without the economic resources to maintain independence. As nations adapt to their aging populations, a partnership among policy makers, family members, and older persons themselves is needed to offer alternatives to meet the needs of elders.  相似文献

This study examines the extent to which fathers are involved in parenting their children under several conditions, using a multivariate regression model. The model includes the age of the child, father role salience, and the father and child's coresidential status as predictors of father involvement. Although nonresidential fathers tend to be less involved than residential fathers under most conditions, this is not the case for fathers of adolescents who find the father role to be at least moderately salient. Explanations for their greater involvement are proposed, focusing specifically on the unique characteristics of the parent-child relationship involving an adolescent child and a nonresidential parent.  相似文献

Effects of perceived merchandise and service quality, relative to competition, on retail store performance are investigated using store traffic and revenue growth as outcome variables. A model is proposed and tested using aggregate customer data and store performance outcomes from a group of stores owned by a national retail organization. Results suggest that both service and merchandise quality exert significant influence on store performance, measured by sales growth and customer growth, and their impact is mediated by customer satisfaction. Implications of the results and future research directions are discussed.  相似文献

Homeless youth often have untreated health problems and experience barriers to care. Existing evidence suggests that homeless youth use emergency departments (EDs) more frequently than other youth. We hypothesized that street youth with access to primary care services would be less likely to utilize EDs for health care. Data were drawn from a study of housing security and changes to it over time among 150 youth (16–20 years) recruited from service agencies for street-involved youth. Our findings show that those with access to primary care were actually more likely to use the ED, suggesting that access may encourage further engagement with the health care system. Findings support the need to better understand why access to primary care increases ED use and what could be done to change this pattern.  相似文献

In aviation, there is currently a lack of accurate and timely situational information, specifically weather data, which is essential when dealing with the unpredictable complexities that can arise while flying. For example, weather conditions that require immediate evasive action by the flight crew, such as isolated heavy rain, micro bursts, and atmospheric turbulence, require that the flight crew receive near real-time and precise information about the type, position, and intensity of those conditions. Human factors issues arise in considering how to display the various sources of weather information to the users of that information and how to integrate this display into the existing environment. In designing weather information display systems, it is necessary to meet the demands of different users, which requires an examination of the way in which the users process and use weather information. Using Human Centered Design methodologies and concepts will result in a safer, more efficient and more intuitive solution. Specific goals of this approach include 1) Enabling better fuel planning; 2) Allowing better divert strategies; 3) Ensuring pilots, navigators, dispatchers and mission planners are referencing weather from the same sources; 4) Improving aircrew awareness of aviation hazards such as turbulence, icing, hail and convective activity; 5) Addressing inconsistent availability of hazard forecasts outside the United States Air Defense Identification Zone (ADIZ); and 6) Promoting goal driven approaches versus event driven (prediction).  相似文献

In response to the very limited and mostly outdated literature on older lesbian sexuality, this exploratory study examined older lesbian sexual identity, romantic relationships, the impact of aging, and experiences of discrimination within these contexts. Utilizing an online survey that recruited via numerous online lesbian communities and snowball sampling, 456 lesbians over the age of 50 responded to closed, Likert scale, and open-ended questions that provided a preliminary understanding of older lesbian sexuality. The results indicated that older lesbians have experienced fluidity in past romantic and sexual relationships, as well as in erotic fantasies, despite strong identification with being lesbian. The findings also indicate a decreased focus on sexuality in the context of relationships, with more focus on stability and continuity. Future research is needed that provides greater specificity and detail about older lesbian conceptions of sexual behavior and sexual identity labels, as well as specific sexual behaviors.  相似文献

Transnational marriages of migrants in Western Europe tend to be seen as hampering integration. In response, policies have been tightened, despite little knowledge on transnational marriages and the effects of such measures. This paper investigates the role of individual preferences and contextual factors such as family reunification policies, group size and development levels of the regions of origin in partner choice of the children of Turkish and Moroccan immigrants. We draw on a novel dataset collected in Austria, Belgium, France, Germany, the Netherlands, and Sweden. Our findings suggest that transnational marriages are partly associated with contextual factors such as a rural origin and family reunification policies. The analysis indicates higher rates of transnational marriages under open family reunification policies, providing tentative evidence of policy effects. On the individual level, the choice of a partner from the parents' origin country is associated with religiosity.  相似文献

Literature in the field of autism is largely deficit driven, with a focus on the inabilities of individuals and the negative experiences of families, often characterised by reductive assumptions and tragedy model interpretations. In addition, family-orientated research has generally overlooked the views and contribution of fathers of disabled children, with positive paternal narratives especially scarce. This study explored 198 father perspectives on perceived benefits of parenting their children with autism, gained in response to an open-ended question in an online survey. Key themes relate to appreciating children’s individual qualities, valuing the strong emotional bond, fathers’ own nurturing role and their associated personal development. Findings will be discussed in relation to models of childhood disability and fatherhood.  相似文献
