With a review of literature on corporate social responsibility (CSR) and its micro‐level impacts, this paper proposes an integrative framework to map undesirable relational outcomes of CSR activities on internal (employees) and external (customers) stakeholders. By adopting a paradox‐based perspective, the authors determine that unexpected, adverse stakeholder reactions to CSR are driven primarily by either performing or belonging tensions, related to exchange‐ and identity‐based stakeholder concerns, respectively. Specifically, contextual and personal influences can trigger and explain undesirable relational outcomes of CSR. On this basis, this paper offers a research agenda for developing a more refined understanding of CSR‐related tensions and a more nuanced perspective on the business case for CSR.  相似文献

Few studies have investigated the sexual development of populations with low cognitive abilities in the United States. This article examines the relationship between cognitive ability and various sexual experiences from adolescence (ages 12 to 18) to early adulthood (ages 28 to 34). Data were from 13,845 respondents interviewed at Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health), a probability sample of adolescents in the United States followed from adolescence to adulthood. Adjusted logistic regression models were used to study relationships between cognitive ability, approximated by the Add Health Picture Vocabulary Test (AHPVT), and experiences of vaginal, oral, and anal sex. After controlling for biological sex, age, race/ethnicity, and socioeconomic status (SES), individuals in the lowest cognitive ability group had significantly lower odds of experiencing each type of sex than those in the average ability group. Although individuals in the highest cognitive ability group had significantly lower odds of experiencing vaginal intercourse than those in the average ability group, this association did not remain significant when analyses were stratified by biological sex. These differences in experiences have implications for future health and warrant further study to understand policy implications for sexual health services and education.  相似文献

Nestedness among species assemblages implies that sites of lower species richness are subsets of richer sites in a regional species pool. This nestedness is a reflection of a non-random process of species loss as a consequence of factors that promote the disaggregation of assemblages. The impoverishment of assemblage diversity is more often observed in fragmented landscapes. This non-random process has important implications for conservation. We recorded 95 species of anurans across 22 protected areas, of which 11 sites were in an urban matrix and 11 were in a non-urban matrix. We found that sites in the urban matrix had lower richness and high values of nestedness with no spatial autocorrelation among geographic distances and species composition. Thus, species were non-randomly distributed across the landscape and a nested pattern was documented from non-urban matrix sites to urban matrix sites. The impoverishment of assemblages toward the urban matrix sites may suggest that protected areas in an urban matrix are less suitable for anuran conservation than those in a non-urban matrix sites. Both the ecological revitalization of protected areas in urban matrix and protection of non-urban forested sites are needed for the conservation of Neotropical anurans.  相似文献

This article explores the way mental health services and social services are orientated on assisting people with a psychiatric disability to participate in different areas of community life. A large research project about community participation in three different countries (Estonia, Hungary and the Netherlands) confirms the findings of other studies that – regardless of geographical location – people with a psychiatric disability have difficulty fulfilling social roles in the community. They are often faced with fewer opportunities than other citizens, due to their health problems, stigma, discrimination and poverty [World Health Organisation. (2011). World report on disability. Geneva: WHO]. An important objective of social work is to help people find their way in society. Surprisingly enough, in all three countries, most social workers are mainly focused on solving individual problems, and not on community participation. Shifting the focus starts by having a clear awareness of the notion of community participation. Social workers have to work both on supporting individuals to find their way in the community (individual support), and on supporting social networks in the community to accommodate persons with a disability on the basis of equal and valued citizenship (community support).  相似文献

Drawing on an ethnographic study of Chinese female tertiary students’ work practices in Melbourne, Australia, this article engages critically with John Urry’s concept of network capital. I show how these students’ work practices link them both into relatively fixed, localized, diasporic employment networks in Melbourne’s Chinese restaurant sector; and into relatively mobile, transnational, digitally mediated trading networks in the micro-entrepreneurial activity of daigou or parallel trading: buying local goods on behalf of customers in China. Based on this case study, I develop three main inter-related claims. First, I argue that geographic and social mooring in place, as well as mobility, can generate benefit for individuals and groups, just as both fixity and mobility may generate disadvantage or risk. Second and relatedly, I propose that social capital cannot operate entirely independently of geography, as Urry’s proposal of network capital as a replacement for the concept of social capital implies. Third, through my development of the concept of ‘feminine network capital’, I show how network capital may take ‘weak’ and tactical, as well as ‘strong’ and strategic forms.  相似文献

Seventy-one U.S. mothers with a physical disability who had a child aged 0 to 3 years responded to a survey about the system of care used for their child. Results indicated that mothers participated in all different types of care (physical, comforting, playing, limit setting, and taking the child outside the home). Partners and participants’ mothers provided the most assistance with care. Mothers were generally satisfied with assistance received from others. This article explores how mothers remain central to their children with others assisting with the child’s care and the impact of such assistance on mothers’ relationships with partners and children.  相似文献

We study the almost sure convergence and rates of weighted sums of associated random variables under the classical assumption of existence of Laplace transforms. This assumption implies the existence of every moment, so we address the same problem assuming a suitable decrease rate on tail joint probabilities which only implies the existence of finitely many moments, proving the analogous characterizations of convergence and rates. Still relaxing further the assumptions on moment existence, we also prove a Marcinkiewicz–Zygmund for associated variables without means, complementing existing results for this dependence structure.  相似文献

We propose a state-space approach for GARCH models with time-varying parameters able to deal with non-stationarity that is usually observed in a wide variety of time series. The parameters of the non-stationary model are allowed to vary smoothly over time through non-negative deterministic functions. We implement the estimation of the time-varying parameters in the time domain through Kalman filter recursive equations, finding a state-space representation of a class of time-varying GARCH models. We provide prediction intervals for time-varying GARCH models and, additionally, we propose a simple methodology for handling missing values. Finally, the proposed methodology is applied to the Chilean Stock Market (IPSA) and to the American Standard&Poor's 500 index (S&P500).  相似文献
