In care-physical activity (care-PA) initiatives, primary care and sports are combined to stimulate PA among adults at risk of lifestyle related diseases. Preliminary results from Dutch care-PA initiatives for adults with a low socioeconomic status (SES) indicate a decrease in participants’ body weight and an improved quality of life, however, the elements that make these initiatives successful are yet to be identified. In total, 19 Dutch health promotion experts participated in our concept mapping (CM) of the effective elements of care-PA initiatives for adults with a low SES. The experts identified 111 effective elements of these initiatives, which were grouped into 11 clusters, focusing on: 1) approaching participants within the care-PA initiative, 2) barriers experienced throughout the initiative, 3) long-term implementation, 4) customizing the care-PA initiative to the target population, 5) social support, 6) structure and guidance, 7) the professionals within the care-PA initiative, 8) the accessibility of the care-PA initiative, 9) targeted behaviour and progression, 10) recruitment and administration, and 11) intersectoral collaboration. CM was useful for creating a valuable overview of these effective elements. Our results could be used to improve the development and implementation of future care-PA initiatives for adults with a low SES.  相似文献

In this article, I investigate commodification discourses and ideologies of English from the perspective of Nepali tourism workers. Drawing data from interviews with porters and trekking guides in Nepal, I argue that English is not seen as merely a transactional means to convey meaning; it works in combination with the traditional form of labor and care in the local economy, establishing itself as a powerful tool to establish closer interpersonal relationships, enhance such interpersonal relationships for economic gains and commodify local identities and cultures in the tourism market. The interview and ethnographic details show that language learners are agentive and capable of making sense of their actions by positioning themselves variously in terms of ethnicity, economic class and job category. These workers think that tourists' linguistic and financial resources are the empowering tools that enable them to travel to locations that they want. They also want to empower themselves with English skills and translocal imaginaries to travel and see the world beyond their immediate reach. Repertoires in English are considered as instruments to mediate their imaginaries and the foreign worlds they want to be part of.  相似文献

This study contributes to the growing body of literature on the outcomes of labour migration by focusing on the effects of migrant legal status on the economic and perceptual measures of migration success. To study the effects of legal status, we use a sample of Central Asian migrant women who work in Russia and of their native counterparts who occupy the same positions on the labour market. Similar to the studies in the developed settings, we find that a temporary legal status is associated with an earnings penalty and that permanent legal status corrects this earning disparity. We also find that both temporary and permanent migrant status is positively associated with perceptions of pay inequality but that, irrespective of these perceptions, both types of migrants are more likely to be satisfied with their jobs than natives. We interpret these findings within the legal and social context of migrant economic incorporation in Russia and relate them to the findings from other migrant-receiving settings.  相似文献

While socioeconomic barriers to learning have been well-documented by education, sociology, and social policy scholars, further research is needed to understand how students with low-socioeconomic status excel in high-performing schools. The collection and analysis of 20 in-depth interviews with female college students from different racial and socioeconomic backgrounds provide rich insights into the stark differences between the educational practices of low and high-SES students. Building on Bourdieu’s conceptualization of how habitus and capital influence practices in the field of education exposes unique, strategic practices that low-SES students use to attain educational success within a system of reproduction and power. While entering a high-performing school is often perceived as a definitive step for accessing high-quality educational resources, my findings illustrate how it is actually an important intermediary step within a more complex process. Increasing educational opportunity and attainment for low-SES students requires improving their access to social, cultural, and economic capital through knowledgeable mentors who contribute to a habitus and portfolio of capital which enable practices to successfully navigate and challenge the educational system.  相似文献

A common risk among adolescents is sexual solicitation, in which an adolescent is asked to provide sexual information, engage in sexual talk, or in sexual activities. Although scholars increasingly address this topic from an intrapersonal perspective, there is little attention to factors of language use and message content. In two focus group studies, we investigated whether adolescent girls consider themselves capable of assessing whether an online stranger is an adult or a peer, the extent to which adolescent girls actually succeed in making this assessment, the strategies they apply to do so, and the content- and language-related cues focused on. Our findings suggest that most of the adolescent girls are confident in their ability to assess whether the stranger is a peer or an adult with possible sexual intentions. However, we also found that only 43% were able to correctly make this assessment. Most of the adolescents seem to apply the passive strategy of uncertainty reduction: They scan the profile page of the stranger, check contact information, and the profile picture. They may choose to apply the interactive strategy to find out more about the online stranger. Important content-related cues that alarm adolescent girls are: ignoring personal questions, showing an exaggerated amount of interest, acting as a friend, and being sexually oriented. Language cues mentioned related to word usage, abbreviations, sentence length, and tone.  相似文献

This paper discusses regression analysis of clustered current status data under semiparametric additive hazards models. In particular, we consider the situation when cluster sizes can be informative about correlated failure times from the same cluster. To address the problem, we present estimating equation-based estimation procedures and establish asymptotic properties of the resulting estimates. Finite sample performance of the proposed method is assessed through an extensive simulation study, which indicates the procedure works well. The method is applied to a motivating data set from a lung tumorigenicity study.  相似文献

While there is a global shift towards smaller families, some groups maintain relatively high fertility rates. The 2013 New Zealand census data were used to investigate the nature of fertility between ethnicities in New Zealand. The NZ Deprivation Index 2013 was used as a measure of socioeconomic status to determine the relationships with fertility. The results mirror research outside of New Zealand in that socioeconomic status is inversely correlated to fertility. Using crude average fertility rates, sole-ethnicity Pasifika and Māori ethnic groups still have substantially higher fertility than sole-ethnicity Europeans and Asians ethnic groups, even when simultaneously accounting for age, socioeconomic status, education, and religious affiliation. Christians have more children than individuals reportedly without any religion, and fertility rates drop on average for mothers who have higher formal qualifications. Our findings suggest that cultural, or other ethnic-specific factors differentially affect fertility for Māori, Pasifika, New Zealand European, and Asians as aggregated ethnic categories, respectively.  相似文献

The discourse of some of the most powerful public figures in today’s world is often incoherent and nonsensical. Incoherent yet authoritative discourse shows that authority does not rest in language but results from non‐linguistic and pre‐textual conditions. The non‐linguistic and pre‐textual conditions are exemplified in an Australian case‐study of a media debate between the Immigration Minister and a refugee, drawing on research by Smith‐Khan (2019a, 2019b). Two such conditions are then examined with reference to academic publics. First, I ask which languages do or do not carry authority, before moving on to speaker identity as a condition of authority. The close association between English and academic excellence has resulted in diminishing the authority of academic publications in languages other than English. The same is true of publications by women and people of colour. I close by reflecting on referencing practices as forms of extending authoritativeness to voices in excluded languages and from excluded scholars in academic publics.  相似文献
