A missing link in the voluminous chain of prior studies on Canadian versus American identity is a comparative analysis of the impact of social studies – especially civics – education on the construction of national identity in these two North American nation-states. This article analyzes curricular documents and secondary-level school textbooks to learn more about how social studies education contributes to constructing a sense of ‘being a Canadian’ versus ‘being an American’ north and south of the 49th parallel.  相似文献

ABSTRACT

Inactivity has been identified as a major contributor to the burden of disease in older women. Study aims were: (a) to assess the personal, social, and environmental facilitators and impediments to physical activity in older women from ethnic communities; and (b) to determine the factors associated with physical activity participation. Older women (aged 60–84 years) were recruited from the local Italian (n = 20), Vietnamese (n = 26) and Anglo-Celtic (n = 26) communities. A survey questionnaire was administered in the participants' preferred language. The most common barriers were: “I am not in good health,” “I am self-conscious about my looks,” “I am too tired,” “I don't have time,” and “The weather is bad.” When comparing the ethnic groups, the Vietnamese women reported fewer barriers than the Italian women (2.6 vs. 5.9). While the Vietnamese women were much more likely to report being “self-conscious about my looks,” the Italian women more commonly reported poor health, being too tired, and not liking exercise as barriers. Overall, those living alone were more likely to be active and those who reported fear of injury, less active. Recognizing ethnospecific differences in the prevalence of barriers may be important when devising strategies to increase activity levels of older women.  相似文献

The Representing Self—Representing Ageing initiative has been funded by the ESRC as part of the New Dynamics of Ageing cross-council research program. It has consisted of four projects with older women using visual research methods and participatory approaches to enable women to articulate their experiences of aging and to create alternative images of aging. Complex research processes were utilized. Innovative methods included the use of art elicitation, photo diaries, film booths, and phototherapy.  相似文献

This research: (1) implements a genetically informed design to examine the effects of fathers’ presence–absence and quality of behavior during childhood/adolescence on daughters’ frequency of substance use during adolescence; and (2) tests substance use frequency as mediating the relation between paternal behavior and daughters’ sexual risk taking. Participants were 223 sister dyads from divorced/separated biological families. Sisters’ developmental exposure to socially deviant paternal behavior predicted their frequency of tobacco, alcohol, and cannabis (TAC) use. Older sisters who co‐resided with fathers who were more (vs. less) socially deviant reported more frequent TAC use during adolescence. More frequent TAC use predicted more risky sexual behavior for these daughters. No effects were found for younger sisters, who spent less time living with their fathers.  相似文献

Accounts of managerial practice in small and medium‐sized firms frequently draw upon notions of formality and informality. In this paper, we explore the relationship between these concepts through an analysis of managerial approaches to employment relations practice in six growing, medium‐sized organizations. Drawing on recent conceptual work on informality and formality, we argue that the use of the terms in previous analyses tends to neglect the co‐dependency of both the concepts and managerial approaches to the employment relationship. We present an alternative conceptualization of formalization and informalization processes that emphasizes synchronization through interactional practices. Through this analysis, we suggest that debate in this area can be reframed through thinking of informality and formality as a dualism rather than a dichotomy, and challenge the notion that small firms must, should or inevitably do move from informality to formality. From this, we construct an inclusive model of formality and informality that better reflects practice and enables further analytical development.  相似文献

Recent research addressing fear of crime largely concerns the causes of that fear; this article expands our understanding of fear of crime by examining whether people cope with their fear individually or collectively. Our guiding questions were two: Do coping strategies differ by those individual-level characteristics established in the fear-of-crime literature? And do strategies differ based upon conceptually distinct types of fear? This research, based on a 1995 telephone survey of a random sample of New Orleans residents, suggests that the answer to both questions is yes. Commodified, individual-level precautionary techniques are explained primarily by characteristics that reflect differential abilities to pay for such precautions. Conversely, collective-level coping strategies are predicted primarily by degree of affective fear based on emotional reactions, regardless of actual levels of victimization.  相似文献

Bayesian inference for partially observed stochastic epidemics   总被引:4,自引:0,他引:4  
The analysis of infectious disease data is usually complicated by the fact that real life epidemics are only partially observed. In particular, data concerning the process of infection are seldom available. Consequently, standard statistical techniques can become too complicated to implement effectively. In this paper Markov chain Monte Carlo methods are used to make inferences about the missing data as well as the unknown parameters of interest in a Bayesian framework. The methods are applied to real life data from disease outbreaks.  相似文献

We compared the extent of parents' differential treatment (PDT) and girls' and boys' perceptions of parents' fairness in middle childhood and adolescence as a function of the gender constellation of the sibling dyad. Further, we examined links between PDT in three domains, parental warmth, parents' temporal involvement, and the allocation of household tasks, and both siblings' self esteem and positivity in the sibling relationship. Participants were mothers, fathers and both first- and secondborn siblings from 385 families. To collect information on siblings' family experiences and well-being, family members were interviewed individually in their homes. During the subsequent 2–3 weeks, 7 evening telephone interviews also were conducted; these focused on siblings' daily activities. Analyses revealed different patterns of PDT for siblings as a function of age and gender constellation, stronger links with self esteem and sibling positivity for perceptions of fairness than for PDT, and different patterns of association with self esteem and sibling relations across domains of PDT. We emphasize the importance of studying the processes through which PDT experiences have implications for siblings.  相似文献

The aim of this study was to determine the impact on risk perceptions of disclosing genetic test results used to estimate the risk of Alzheimer's disease (AD). Adult children (n = 149) of people with AD were randomized to one of two groups--Intervention group: lifetime risk estimates of AD based on age, gender, family history, and Apolipoprotein E (APOE) genotype; Control group: lifetime risk estimates of AD based on the same risk factors excluding APOE genotype. Perceptions of personal risk (PPR) for AD were assessed six weeks after risk assessments. PPR were correlated with actual lifetime risk estimates (r = 0.501; p < 0.0001). After controlling for lifetime risks communicated to participants, age, and number of affected relatives, PPR scores among those with an epsilon4-positive test result (the test result associated with increased AD susceptibility) (adjusted mean: 3.4 (SD: 0.7)) were not different from the PPR scores in the Control group (adjusted mean: 3.4 (SD: 0.7) (F1,91= 1.98; p = 0.162). Again, controlling for lifetime risk estimates, age, and number of affected relatives, the PPR score of those receiving an epsilon4-negative test result was significantly lower (adjusted mean: 3.1 (SD: 0.8)) than those in the Control group (adjusted mean: 3.4 (SD: 0.7) (F1,95 = 6.23; p = 0.014). Perceptions of risk of developing AD are influenced by genetic test disclosure in those receiving epsilon4-negative, but not those receiving epsilon4-positive test results. Despite the reduced perceptions of risk in the former group, there was no evidence of false reassurance (i.e., perceiving risks as equal to or lower than population risks of AD), although this possibility should be assessed in other testing contexts.  相似文献
