Graduation model interventions represent a new wave of anti‐poverty programming that seeks to offer a sustainable pathway out of poverty. An expanding evidence base points towards positive economic outcomes at household level but little is known about impacts on child well‐being. This paper investigates children’s well‐being in Burundi during and after participation in a graduation model programme using a longitudinal mixed‐methods approach. The programme is found to improve child well‐being, particularly in relation to housing, food security and education. Covariate shocks undermine sustainability of effects but greater knowledge, experience and prioritisation of children’s needs contribute to harnessing improved outcomes.  相似文献

This special section shifts analytical attention onto efforts undertaken by dispersed sets of actors operating in online communities to mobilize a novel internet‐based technology that mysteriously appeared at the height of market volatility in 2008. Applications of blockchain technologies and the challenges presented to longstanding patterns of financial globalization are analysed by a group of scholars with backgrounds in anthropology, political science and sociology. This introductory article first elaborates what blockchain technologies consist of before foreshadowing the insights that the following interdisciplinary investigations yield for comprehending the implications that technological changes pose for global finance specifically and globalization more generally.  相似文献

Social capital is the whole set of shared norms, values, attitudes, and beliefs that promote cooperation among individuals within the community and that has proved to be a key factor in explaining development processes. This article aims to provide an analytically reliable notion of social capital within the farming sector and a methodological tool for empirically measuring how social capital is accumulated at the farmer level. The theoretical framework proposed is based on the multidimensionality of the complex concept of social capital. Thus, to develop a comprehensive index for social capital, we identify three dimensions of the concept, structural, relational, and cognitive social capital, each one also comprising several subdimensions. This integrative approach permits creation of a composite indicator of the agricultural social capital accumulated at the farmer level, further identifying socioeconomic factors that influence its accumulation at that level. We empirically apply this methodological approach to farmers in Andalusia in southern Spain as a case study. This research provides an interesting starting point for informing policymakers about social capital and helping them implement the necessary programs to facilitate sustainable development in the agricultural sector.  相似文献

Unique dream patterns are related to psychopathological distress in adults. In adolescence, this was investigated almost exclusively regarding nightmares. This longitudinal study examines developmental trajectories of various adolescent‐reported dream patterns, and their associations with parent‐reported psychopathology (internalization and externalization problems) in early adolescence. Ninety‐four 10‐ to 11‐year‐old normally developing children completed a week of sleep, dreaming, and pubertal development assessments. Parents reported behavior problems. Assessments were repeated after 1 and 2 years. Reports of unusual dreams decreased over time, and dream recall decreased among girls. Internalizing symptoms longitudinally predicted an increase in dream recall and unusual dreams. Moreover, unusual dreams longitudinally predicted increased behavior problems (internalization and externalization). Assessing dream patterns during early adolescence may help early detection of covert psychopathological distress.  相似文献

Relationships between parenting styles, academic performance, and the mediating effects of motivation, goal orientation, and self-efficacy were examined. One hundred forty-eight high school students participated, including 58 males and 90 females. The Parenting Style/Parental Involvement Questionnaire was used to measure students' perceptions of their parents' parenting styles. The Intrinsic-Extrinsic Orientation Scale measured students' motivation. The Patterns of Adapted Learning Survey measured participants' goal orientation and academic self-efficacy. Adolescents who reported their parents as having a more authoritative parenting style were found to demonstrate more intrinsic motivation in their academic pursuits. Future implications for intervention and research are discussed.  相似文献

This study looks at how gender relates to a critical economic behavior—savings activity. We start with the proposition that gender is not merely an additional variable to explain savings choices. Gender is the primary type of social categorization in the U.S. today. Therefore, other variables will be differently relevant to savings depending on gender. We use a national survey, the 2006 Economic Decision Making Survey conducted by Michigan State University’s Institute for Public Policy and Social Research, to examine the proposition. Basic frequencies reveal nonsignificant differences in savings participation across gender, but regression analysis including interactions of gender with other key variables reveals that multiple aspects of individuals’ lives are influenced by gender to predict savings plan participation.  相似文献

This paper evaluates the effects of a labor market reform in Spain that removed restrictions on fixed‐term or temporary contracts. Our empirical results are based on longitudinal firm‐level data that cover observations before and after the reform. We posit and estimate a dynamic labor demand model with indefinite and fixed‐term labor contracts, and a general structure of labor adjustment costs. Experiments using the estimated model show important positive effects of the reform on total employment (i.e., a 3.5% increase) and job turnover. There is a strong substitution of permanent by temporary workers (i.e., a 10% decline in permanent employment). The effects on labor productivity and the value of firms are very small. In contrast, a counterfactual reform that halved all firing costs would produce the same employment increase as the actual reform, but much larger improvements in productivity and in the value of firms.
