ABSTRACT

The World Health Organization (WHO)’s Age-Friendly Community (AFC) initiative has gained worldwide momentum. Yet, measures have not been validated in regions with various levels of socio-economic development. This article used a nationally representative dataset in China to (a) analyze community-level measures within the framework of AFC and (b) compare the age-friendliness between rural and urban settings in China. Chi- square and t-tests examined the rural and urban differences. Results suggest that many AFC concepts did not apply well in developing areas. The Chinese survey measured important environmental aspects in developing regions that were missing in the WHO AFC framework.  相似文献

This study examined prospective associations between the family context and adolescents’ romantic relationships as moderated by adolescents’ gender and culture among Mexican American families (= 189). Adolescents at Time 1 (early adolescence) were on average 12.29 years of age (SD = 0.50) and 54% female. Mothers and fathers reported on family structure and dynamics during early adolescence, and youth reported on their romantic relationship involvement and quality during middle and late adolescence. Results from path analyses indicated that family structure and dynamics (supportive parenting, consistent discipline, and parent–adolescent and interparental conflict) were associated with adolescents’ romantic involvement and quality, and with differences by adolescents’ gender and culture. Findings highlight Mexican American family contexts that contribute uniquely to adolescents’ romantic relationships.  相似文献

As US Internet penetration rates have climbed, digital divide researchers have largely shifted attention to differences in Internet skills. Interviews with 72 low-income US residents from both a large metropolitan city and a medium-sized Midwestern town, however, reveal that many people still struggle to maintain physical access, supporting technology maintenance theory. Technology maintenance theory argues that although most of the US poor now use digital technology, access is unstable and characterized by frequent periods of disconnection. As a result, low-income users must work to maintain access, often experiencing cycles of dependable instability. In these interviews, nearly all used the Internet, but technology maintenance practices were widespread, including negotiation of temporarily disconnected service, broken hardware, and logistic limitations on public access. As a result, participants had limited access to health information and employment, and biased attitudes toward technology. That is, in some cases, negative attitudes toward Internet adoption reflected a rational response to disconnection rather than cultural norms or fears of the Internet, as suggested by previous research. Findings support and extend the theory of technology maintenance by emphasizing a shift in the US digital divide from issues of ownership to issues of sustainability; they also provide insight into the interrelated nature of access and attitudes toward technology. This new theoretical approach complements other theoretical approaches to the digital divide that foreground a contextualized understanding of digital disparities as embedded within a history of broad social disparities.  相似文献

Gray squirrels (Sciurus carolinensis) use trees for various resource needs in urban and nonurban settings; particularly, mast producing trees which are the preferred and supplemental foods for the species. During periods of abundant mast availability, less time will be invested in foraging because of the higher success rate stemming from the increased ability to locate food items. Conversely, in periods of reduced mast availability, more time will be invested in foraging. However, correlations between food availability and foraging effort are only supported under the assumption that gray squirrels rely significantly on mast as a preferred or supplemental food source (Nixon et al, J Wildl Manag 39:1–25, 1975). Therefore, given the seasonal variation in the availability of mast, there should also be correlating seasonal variations in foraging effort. In this paper, we will examine daily and seasonal time-activity budgets of gray squirrels in urban areas. We studied the time-activity budgets of gray squirrels in six urban parks in Baltimore, MD. Seasonal frequencies of activities were expressed as percent occurrence and seasonal differences in activities were analyzed using a Tukey Studentized multiple range test for significance. We found that the activity with highest percent occurrence was forage (2003, summer: 23.8 %, fall: 25.9 %; 2004, summer: 23.1 %, fall: 25.2 %), followed by feed and store, all activities associated with food. Results of the Tukey Studentized multiple range test for seasonal differences of activities yielded significant results (P?P?=?0.003); fall 2003 and fall 2004 (P?=?0.048).  相似文献

Urban atmospheres can have high concentrations of particulate organic carbon (oC) but the rate and fate oC deposition in near-urban ecosystems are rarely quantified. We collected atmospheric particulate matter in Phoenix, AZ and applied these samples to Sonoran Desert soils in a series of laboratory incubation experiments. The addition of fine particulate matter (<2.5 μm aerodynamic diameter) increased microbial respiration in soils collected from the interspaces between desert shrubs. The increase in soil respiration was equivalent to 25% to 30% of the added oC. In contrast, we did not detect increases in respiration when coarse particulate matter (>2.5 μm aerodynamic diameter) was added to interspace soils, suggesting that coarse particulate oC is recalcitrant to microbial decomposition. Due to comparatively higher background levels of C mineralization, we rarely detected changes in microbial respiration when fine or coarse particulate oC was added to soils collected beneath shrub canopies. We measured total atmospheric C concentrations within and surrounding Phoenix and, using inferential methods, estimated rates of deposition that ranged from 0.02 to 0.58 mg C m−2 d−1 for fine particles and from 0 to 6.15 mg C m−2 d−1 for coarse particles. Results show that fine atmospheric particulate matter deposited at low rates downwind of Phoenix is a labile oC substrate for soil heterotrophs. In contrast, oC deposited at higher rates as coarse particulate matter may accumulate in soils due to slow microbial decomposition rates.  相似文献

Prejudices against older adults have been shown to reduce effective care delivery and impact long-term health outcomes for older adults. In an effort to combat these prejudices, intergenerational—and often unidirectional—programs focus on challenging ageism. The PALETTE program takes this further to employ collaborative activities as a way to challenge the gerontophobia that often accompanies ageism. Promoting Art for Life Enrichment Through Transgenerational Engagement (PALETTE) is an innovative program for interprofessional undergraduate and graduate students that combines intergenerational arts activities with formal education on aging, ageism, and gerontophobia. Having demonstrated success in changing the attitudes of students, PALETTE serves as a model for an internationally replicable program that has the potential to improve person-centered care while educating future generations of older adults about positive, optimal aging.  相似文献
