With soaring food prices in recent years has come alarm about rising poverty in the developing world. Less appreciated, however, is that many of the poor in agricultural economies may benefit from higher wages. This study finds that wages for manual labor in rural India, both within and outside agriculture, rose faster in districts growing more of those crops with large producer price run‐ups over the 2004–2009 period. Based on a general equilibrium framework that accounts for such wage gains, rural households across the income spectrum are found, contrary to more conventional welfare analysis, to benefit from higher agricultural prices.

This paper reports the results of a quantitative 42-item survey that explored foster, adoptive, and kinship parents’ (N = 160) utilization of different types of respite services (formal, informal, and a mixture of formal and informal), as well as their impressions of the impact of respite care on aspects of their lives related to family cohesion and stability, caring for their children, and their personal wellbeing. An exploratory cross-sectional, survey design was used to assess both the formal and informal respite care experiences of the foster, adoptive, and kinship caregivers. Two-tailed Fisher’s exact tests were used to examine the relationship between the type of respite received and caregivers’ respite experiences. Findings indicated that parent experiences differed depending on the type of respite services they received. Specifically, parents who used a mixture of formal and informal respite reported positive experiences related to respite more frequently than the other two types of respite groups, while those who received only informal respite reported less benefit than others. Parents who used formal respite (either alone or mixed with informal respite) reported greater stress reduction. The greatest increase in family stability was reported by parents who received a mix of informal and formal respite. While this study revealed clear benefits for families to using both informal and formal respite services, the findings suggest that formal respite care was helpful to parents regardless of whether used alone or in combination with informal care.  相似文献

The Sustainable Development Goals (SDGs) herald a new phase for international development. This article presents the results of a consultative exercise to collaboratively identify 100 research questions of critical importance for the post‐2015 international development agenda. The final shortlist is grouped into nine thematic areas and was selected by 21 representatives of international and non‐governmental organisations and consultancies, and 14 academics with diverse disciplinary expertise from an initial pool of 704 questions submitted by 110 organisations based in 34 countries. The shortlist includes questions addressing long‐standing problems, new challenges and broader issues related to development policies, practices and institutions. Collectively, these questions are relevant for future development‐related research priorities of governmental and non‐governmental organisations worldwide and could act as focal points for transdisciplinary research collaborations.  相似文献

Transformational leaders are known to inspire and motivate their followers, thereby leading to enhanced job satisfaction. Job satisfaction is an intellectual concept regarding individuals’ attitudes toward their jobs. This study asserts that the underlying mechanisms for transformational leadership to affect employee satisfaction are trust in the community, including the leader (that is, organization) and trust in the self, namely self‐efficacy. Leadership is specifically associated with continual transformations in the higher educational context, and collectivist cultures may manifest different processes underlying the transformational leadership–satisfaction relationship. This study investigated the mediating effects of trust and self‐efficacy on the relationship between transformational leadership and job satisfaction. The study sample included academicians from a nonprofit higher education institution in Turkey. The data were analyzed using structural equation modeling. The results showed that the relationship between transformational leadership and job satisfaction is fully mediated by both trust and self‐efficacy. The mediator effect of trust was shown to be stronger than self‐efficacy, which is assumed to be the result of the cultural context. The results are discussed in the context of employee satisfaction and cultural determinants of employee satisfaction.  相似文献
