ABSTRACT

By 2060, the number of Americans aged 65 and older is expected to more than double, while the number of Americans aged 85 and older is expected to nearly triple. As the nation's aging population grows, older adults will need to rely on social support services, such as transportation and housing services, in order to remain active and lead independent lives. In this study we use data collected from the elderly supplement of the Southeastern Pennsylvania Household Health Survey (SPHHS) (n = 3,042) to explore the relationship between the availability of elderly specific social service providers and utilization of social support services among older adults. We find that while the number of elderly specific social service providers can increase use of social support services among older adults, its impact is relatively minimal. We find that individual factors, instead, are stronger predictors of service use. This is a finding that should be particularly encouraging for elder care providers who may not have the resources needed to undertake large structural changes (like building new facilities). Still, future research should explore how the availability of a broader range of elderly specific social services (than explored in this study) impacts use.  相似文献

We liaised with a wharekura (Māori language immersion school) to translate and disseminate an online survey for a group of Māori youth in Southland, New Zealand (NZ). The focus of this article is not results, but the processes of respondent orientation and engagement to more genuinely include Māori in a youth survey. An online survey about transport and well-being was conducted with older teenagers from 12 schools, including the wharekura. After working with wharekura staff and students, the survey was translated from English into te reo Māori using best-practice methods. Steps were taken to safeguard authentic engagement, including how the survey translation was conducted, and how the survey data were shared. This NZ-specific experience adds to the literature about the practice of applying the principle of respondent orientation to the process of translating an existing survey into te reo Māori, demonstrating commitment to some Treaty of Waitangi principles. While this is not a kaupapa Māori research project, it is informed by some kaupapa Māori principles. This may be seen as a limitation of this work; however, we believe there are many positive experiences and lessons to be learned from our approach.  相似文献

As survey response rates decline, correlates of survey participation may also be changing. Panel studies provide an opportunity to study a rich set of correlates of panel attrition over time. We look at changes in attrition rates in the American National Election Studies from 1964 to 2004, a repeated panel survey with a two-wave pre-post election design implemented over multiple decades. We examine changes in attrition rates by three groups of variables: sociodemographic and ecological characteristics of the respondent and household, party affiliation and political and social attitudes recorded at the first interview, and paradata about the first wave interview. We find relatively little overall change in the pre-post election panel attrition rates, but important changes in demographic correlates of panel attrition over time. We also examine contact and cooperation rates from 1988 to 2004.  相似文献

The daily evolution of the price of Abbey National shares over a 10-week period is analysed by using regression models based on possibly non-symmetric stable distributions. These distributions, which are only known through their characteristic function, can be used in practice for interactive modelling of heavy-tailed processes. A regression model for the location parameter is proposed and shown to induce a similar model for the mode. Finally, regression models for the other three parameters of the stable distribution are introduced. The model found to fit best allows the skewness of the distribution, rather than the location or scale parameters, to vary over time. The most likely share return is thus changing over time although the region where most returns are observed is stationary.  相似文献

The radical shift by news audiences away from newspaper to motion media (video stories on TV, web, cell phones, handhelds) prompted the assessment of media modality (text, text + picture, video) and source (public relations, news, user-generated content [UGC]) effects on credibility and more importantly perceived veridicality, a perception of an object as being accurate and believable regardless of the source, as well as impact of messages. The findings revealed that motion media modality significantly enhances believability judgments and perceived veridicality, which is independent of source cue, in which news source garnered no greater credibility than PR or UGC source.  相似文献

Chronic loneliness is a risk factor associated with adverse psychological, physical, and academic outcomes. Converging evidence suggests that young children experience and can reliably report on their own loneliness: thus, a clearer understanding of the risk factors for child loneliness is needed. The aims of this study were two-fold: (a) to examine if temperament (i.e., negative affect, effortful control, inhibitory control), and attachment security assessed at the age of four predict loneliness at the age of six and (b) to determine if social competence at the age of five mediates the relation between temperament and attachment security at the age of four and loneliness at the age of six. Participants included a diverse sample of 796 4-year-old children, about half of whom were male. Results of hierarchical regression analyses indicated that lower levels of effortful control and inhibitory control at the age of four significantly predicted greater loneliness at the age of six. Also, while lower levels of negative affect (NA) and higher levels of effortful control and attachment security at the age of four significantly predicted higher levels of social competence at the age of five, social competence at the age of five did not predict loneliness at the age of six. There was no evidence that social competence at the age of five mediated the relation between the age of four temperament, attachment security, and the age of six loneliness. These findings reveal that early self-regulation is associated with later child-reported loneliness and that intervention for children who struggle with behavioral regulation may be effective in decreasing risk for later loneliness.  相似文献
