The aims of this investigation were (1) to measure the impact of arts-related activities on the perceived quality of life of a representative sample of British Columbians aged 18 years or more in the spring of 2007, and (2) to compare the findings of this study with those of a sample of 1,027 adults drawn from five B.C. communities (Comox Valley, Kamloops, Nanaimo, Port Moody and Prince George) in the fall of 2006. Seven hundred and eight British Columbians responded to a mailed out questionnaire, and the working data set was weighted by age and education to match the 2006 census statistics for the province, yielding a fairly representative sample. Speaking quite generally, about 62.0% of the results for the two samples are very similar. In particular, in both surveys we found that (a) among arts-related activities in which people participate relatively infrequently (i.e., participation is counted in times per year rather than in hours per week), live theatre is supreme in the strength of its positive correlation with respondents’ perceived quality of life measured in 7 different ways, and (b) compared to 4 demographic variables (age, education, household income and body mass index), household income had the highest average, positive correlation with 7 different measures of respondents’ overall life assessments, namely, self-assessed general health, satisfaction with life as a whole (single item), happiness, satisfaction with the quality of life, satisfaction with life as a whole (5-item index), contentment with life (5-item index) and subjective wellbeing (4-item index). Different results were found in the province-wide versus the five-communities survey for the following, among other things, (a) compared to all 7 life assessment measures, for the province, satisfaction with the quality of life and happiness had the largest number of significant correlations with arts-related activities measured in hours per week engaged, while for the five communities, the single measure of satisfaction with the quality of life had the largest number of significant correlations, and (b) For the province, compared to all 7 life assessment measures, satisfaction with the quality of life had the largest number of significant correlations with arts-related activities measured in times per year engaged; for the five communities, compared to all 7 life assessment measures, self-assessed general health had the largest number of significant correlations with arts-related activities measured in times per year engaged.  相似文献

There has been a dramatic increase in the number of new HIV diagnoses among people aged 50 to 64 in the United States, and according to the Centers for Disease Control and Prevention (CDC), in just 7 years (by 2015) 50% of those living with AIDS will be aged 50 or older. To address this public health concern, viable HIV/AIDS prevention and treatment options for individuals over the age of 50 are necessary. This article discusses the No One Is Immune initiative that planned, implemented, and coordinated evidence- based HIV/AIDS prevention and education programs specifically tailored for middle-aged and older adults. Guided by the health belief model, an educational conference entitled "Sexuality, Medication, and HIV/AIDS in Middle and Later Adulthood" was conducted along with research activities that assessed HIV/AIDS knowledge gained using both qualitative and quantitative measures. This project can be replicated by other providers within the aging network.  相似文献

Using behavioral self-regulation processes may facilitate exercise among older women with heart disease. Data from women in a heart disease-management program (n = 658, mean 73 years), was used to explore associations among exercise self-regulation components (i.e., choosing to improve exercise and observing, judging, and reacting to one's behavior) and exercise capacity. General linear models showed that choosing exercise predicted higher exercise self-regulation scores postprogram and 8 months later. In turn, these scores predicted greater improvements in exercise capacity concurrently and 8 months later. Interaction analyses revealed that the effect of self-regulation on exercise capacity was stronger among women who chose to work on exercise.  相似文献

In the last decade the Maltese population has seen an influx of overseas-born individuals. This has been largely due to Malta’s access to the European Union and the increased intake of refugee immigrants. These immigration trends have resulted in changes in population composition, with the overseas-born population increasing from 17,740 (4.7%) in 1995 to 24,560 (6.1%) in 2005. There has also been an increase in the proportion of births registered in Malta to overseas citizens, including citizens of non-EU Europe (1.1%); the African continent (1.5%); America (0.3%); and Asia (0.8%). About ten per cent of marriages in Malta are between a Maltese spouse and a foreigner. The data suggest that the Maltese population is slowly becoming more cosmopolitan, a trend that is gradually changing the ethnic composition of the Maltese community.  相似文献

Gambling prevalence studies are typically conducted within a single (landline) telephone sampling frame. This practice continues, despite emerging evidence that significant differences exist between landline and mobile (cell) phone only households. This study utilised a dual-frame (landline and mobile) telephone sampling methodology to cast light on the extent of differences across groups of respondents in respect to demographic, health, and gambling characteristics. A total of 2,014 participants from across Australian states and territories ranging in age from 18 to 96 years participated. Interviews were conducted using computer assisted telephone interviewing technology where 1,012 respondents from the landline sampling frame and 1,002 from the mobile phone sampling frame completed a questionnaire about gambling and other health behaviours. Responses across the landline sampling frame, the mobile phone sampling frame, and the subset of the mobile phone sampling frame that possessed a mobile phone only (MPO) were contrasted. The findings revealed that although respondents in the landline sample (62.7 %) did not significantly differ from respondents in the mobile phone sample (59.2 %) in gambling participation in the previous 12 months, they were significantly more likely to have gambled in the previous 12 months than the MPO sample (56.4 %). There were no significant differences in internet gambling participation over the previous 12 months in the landline sample (4.7 %), mobile phone sample (4.7 %) and the MPO sample (5.0 %). However, endorsement of lifetime problem gambling on the NODS-CLiP was significantly higher within the mobile sample (10.7 %) and the MPO sample (14.8 %) than the landline sample (6.6 %). Our research supports previous findings that reliance on a traditional landline telephone sampling approach effectively excludes distinct subgroups of the population from being represented in research findings. Consequently, we suggest that research best practice necessitates the use of a dual-frame sampling methodology. Despite inherent logistical and cost issues, this approach needs to become the norm in gambling survey research.  相似文献

In sum, this paper examines the core determinants of lottery sales in Portugal. With panel data analysis covering 18 Portuguese districts and 5 years, this study explains the variations in a district’s per-capita lottery sales in terms of key theoretical hypotheses such as per capita district income, age, education index, gender and religion. This paper concludes that the richer Portuguese districts spend more than the poorer districts and there is an inverted-U relationship between lottery sales and per capita income. The paper also concludes that married Catholic citizens spend more on lottery products than others and that the level of education returns a negative effect on lottery spending.  相似文献

Growing ethnic and cultural diversity within Europe has brought increased attention to the impact and inclusion of immigrant populations and has also presented societies with valuable opportunities for intercultural learning between diverse groups. Using the International Civic and Citizenship Study data from 24 European education systems, in this paper we explore whether fostering an atmosphere of inclusion in schools relates to select attitudes and behaviours typically associated with an inclusive society, particularly among immigrant students. Our study is able to tease out some of the differences related to social class among immigrant students, opening up important avenues for discussion and future research. According to our findings, first generation immigrant students from higher socio-economic status backgrounds tended to have significantly more negative attitudes toward their resident country. Findings also collectively suggest that local-level practices, such as improving immigrant student participation in schools and positive relations between immigrant students and teachers, could be significant factors in fostering an inclusive society. Based on these results, we describe several education policies and practices that can promote greater inclusion, such as encouraging increased civic participation within the school and community, and providing a forum where students can contribute to school governance.  相似文献

A controversial proposal to pilot the training of child protection social workers through an intensive work-based route in England is being supported and funded by the UK Government. Frontline, the brainchild of a former teacher, locates social work training within local authorities (‘the agency’) rather than university social work departments (‘the academy’) and has stimulated debate amongst social work academics about their role in shaping the direction of the profession. As a contribution to this debate, this paper explores the duality of social work education, which derives its knowledge from both the academic social sciences and the experience of practice within social work agencies. While social work education has traditionally been delivered by the academy, this paper also explores whether the delivery of training in the allied professions of probation and nursing by ‘the agency’ is equally effective. Finally, this paper explores the Helsinki model which achieves a synergy of ‘academy’ and ‘agency’. It suggests that there are alternative models of social work education, practice and research which avoid dichotomies between the ‘academy’ and the ‘agency’ and enable the profession to be shaped by both social work academics and practitioners.  相似文献

The aims of this article are threefold: One, to focus on the advertising and marketing communications situating the presence of the USA in India. Two, to address three issues concerning the where, how, and impact dimensions of marking the US presence in Indian advertising. In that process an attempt will be made to integrate three aspects of advertising, namely: marketing, media, and linguistics. Three, to account for US corporate culture as it manifests itself in advertising. Central to our discussion are two product types: consumer products (e.g. Coke, Pepsi, Kellogg’s cereals, or Cadbury’s chocolates) and socially-sensitive, or ‘taboo’, products (e.g. condoms, alcohol, and breath fresheners).  相似文献

Recent research has revealed the important role of multimodal object exploration in infants' cognitive and social development. Yet, the real‐time effects of postural position on infants' object exploration have been largely ignored. In the current study, 5‐ to 7‐month‐old infants (= 29) handled objects while placed in supported sitting, supine, and prone postures, and their spontaneous exploratory behaviors were observed. Infants produced more manual, oral, and visual exploration in sitting compared to lying supine and prone. Moreover, while sitting, infants more often coupled manual exploration with mouthing and visual examination. Infants' opportunities for learning from object exploration are embedded within a real‐time postural context that constrains the quantity and quality of exploratory behavior.  相似文献
