In order to provide competent care to aging parents, adult children, and older parents must renegotiate long-standing privacy boundaries that allow caregivers access to parents’ private information. It is reasonable to surmise that caregivers encounter privacy coordination issues when attempting to care for their aging parent. This study utilizes Communication Privacy Management theory to explore what content is considered private and what privacy coordination issues arise in the context of eldercare. Results from 27 in-depth interviews with adult children caring for an aging parent suggest that information concerning parents’ future care, health and well-being, and (in)capabilities were marked private. The findings also detail three disruptions to privacy coordination, including parental caregivers’ ambivalence toward managing parents’ care-related information. Critical implications of the study are discussed, which include how privacy turbulence may be a functional catalyst for boundary recalibration. 相似文献

Abstract This study explores the bio-psychosocial context of HIV/AIDS in which eleven HIV-positive activist women from Khayelitsha negotiated the process of disclosing their HIV-positive status to significant others, specifically biological household members. The study is based on the narratives of a group of HIV-positive peer-educators in Cape Town, South Africa. The results suggest that community perceptions of HIV/AIDS are shaped by a wide variety of factors particular to the socio-cultural and political context of HIV/AIDS in South Africa. The process and outcomes of disclosure to others occurs within this shifting web of meanings, and in turn, reshapes them as people respond to the person who has just disclosed. Eight out of the eleven women disclosed to a close biological household member as these significant-others provided, or had the potential to provide, the appropriate support. Six of the eleven participants disclosed during the symptomatic phases of HIV/AIDS, while five were asymptomatic at the time. Four of the five who disclosed when asymptomatic were diagnosed while pregnant and had never experienced severe opportunistic infections. Additionally, these same four disclosed some time after diagnosis (nine months > t < two years). Of the six who disclosed in a state of ill-health, five disclosed immediately after diagnosis in order to access health-related social support. At this time, concerns regarding health and mortality superseded fears of rejection and discrimination due to AIDS-related stigma. The perceived potential benefits (social and health-related support) outweighed the perceived risks (stigmatisation and discrimination). When participants had never experienced serious illness, they disclosed in order to educate loved-ones, gain emotional support or challenge false popular perceptions of HIV/AIDS. 相似文献

Urbanisation is widely considered to promote the establishment of non-native species, but there is limited empirical evidence of the ecological factors driving their responses. The grey squirrel Sciurus carolinensis (Gmelin 1788) is native to North America, but is widespread in the UK and is starting to spread across Europe. It is regarded as one of the world’s worst invasive animals due to its adverse impacts on native biodiversity. We use the non-native grey squirrel population in Sheffield (UK) as a case study to assess which factors limit its distribution and abundance in urban environments. In 2010 the city-wide population of adult squirrels peaked at an estimated 6539 in autumn (0.46 squirrels/ha), with maximum local densities of 8.29/ha. These densities appear to be slightly lower than those recorded in urban environments in the species’ native range. Grey squirrels occurred more frequently at urban sites with larger amounts of green-space in the surrounding region. Local habitat characteristics were, however, more powerful predictors of urban grey squirrel occurrence and abundance than regional availability of green space. Canopy cover, seed bearing trees and supplementary feeders, provided for garden birds, positively influenced grey squirrels. The potential for grey squirrels to connect city dwellers with nature thus appears to be highest in urban locations that have considerable capacity to support native biodiversity. The beneficial impacts of supplementary feeding on grey squirrel populations is notable given concerns that squirrels can adversely influence bird populations. These habitat associations also imply that grey squirrels typically respond negatively to urbanisation, which challenges arguments that urbanisation favours exotic species. 相似文献

The “Arab Spring” was a surprising event not just because predicting revolutions is a difficult task, but because current theories of revolution are ill equipped to explain revolutionary waves where interactive causal mechanisms at different levels of analysis and interactions between the units of analysis predominate. To account for such dynamics, a multidimensional social science of revolution is required. Accordingly, a meta-framework for revolutionary theory that combines multiple levels of analysis, multiple units of analysis, and their interactions is offered. A structured example of theory building is then given by detailing how the development of world cultural models and practices challenge existing political structures, affect mobilization processes, and make diffusion more likely. A structured example of study design using qualitative comparative analysis of 16 Middle Eastern and North African countries provides support for the interaction of subnational conditions for mobilization, state-centered causes, and transnational factors, including a country’s linkage to world society, as one explanation of the Revolutions of 2011. 相似文献

Following the extension from linear mixed models to additive mixed models, extension from generalized linear mixed models to generalized additive mixed models is made, Algorithms are developed to compute the MLE's of the nonlinear effects and the covariance structures based on the penalized marginal likelihood. Convergence of the algorithms and selection of the smooth param¬eters are discussed. 相似文献
