This paper explores the role of social capital in creating social innovation ecosystems and fostering social impact. We examine two cases, chosen for their pioneering experiences in the field of tackling poverty in Latin America: Socialab and Compartamos con Colombia. Focusing on their structure of interactions (through network-level and node-level indicators), we examine the structural characteristics of the two ecosystems studied. We then correlate relational data to study the association between perceived social impact and the structural aspects. Results confirm heterophilic ecosystems and high levels of perceived impact as good drivers for strengthening future collaborations.  相似文献

The Southampton Rebellion of 1831, Nat Turner’s Rebellion, stands as the most famous slave rebellion in American History. Historians have studied the rebellion extensively often focusing on Turner’s biography, the incident’s violent sequence of events, and the wide social, cultural, and political impact of the rebellion. The most recent scholarship on the Southampton Rebellion focuses on the wider community that produced the violent event that resulted in the death of nearly 60 whites and an uncountable number of people of color. African-American children made up a significant demographic in antebellum Southampton. They were present everywhere, just as children were present in most antebellum communities. Yet their appearances in the trial records associated with the Southampton Rebellion are all but unstudied. The Southampton Rebellion was not the result of Nat Turner’s singular genius focused on immediate results. It was a rebellion constituted in the community with future liberation in mind. Children, the literal embodiment of slavery’s future, then were necessarily included and involved. This article engages the extensive court documents associated with the Southampton Rebellion’s aftermath to investigate the possible role of children in the rebellion and their significance to the resistance of enslaved communities.  相似文献

Research has demonstrated that humans detect threatening stimuli more rapidly than nonthreatening stimuli. Although the literature presumes that biases for threat should be normative, present early in development, evident across multiple forms of threat, and stable across individuals, developmental work in this area is limited. Here, we examine the developmental differences in infants' (4‐ to 24‐month‐olds) attention to social (angry faces) and nonsocial (snakes) threats using a new age‐appropriate dot‐probe task. In Experiment 1, infants' first fixations were more often to snakes than to frogs, and they were faster to fixate probes that appeared in place of snakes vs. frogs. There were no significant age differences, suggesting that a perceptual bias for snakes is present early in life and stable across infancy. In Experiment 2, infants fixated probes more quickly after viewing any trials that contained an angry face compared to trials that contained a happy face. Further, there were age‐related changes in infants' responses to face stimuli, with a general increase in looking time to faces before the probe and an increase in latency to fixate the probe after seeing angry faces. Together, this work suggests that different developmental mechanisms may be responsible for attentional biases for social vs. nonsocial threats.  相似文献

Background

Asthma affects 12.7% of pregnancies in Australia. Poorly controlled asthma is associated with increased maternal and infant morbidity and mortality. Optimal antenatal management of asthma during pregnancy has the potential to reduce complications relating to asthma. Evidence-based clinical practice guidelines help to translate health research findings into practice and when implemented can improve health outcomes. National and International guidelines currently provide recommendations for optimal asthma care in pregnancy.

Aim

To appraise the existing asthma in pregnancy guidelines with respect to their evidence for recommendations, consistency of recommendations and appropriateness for clinical practice.

Method

The Appraisal of Guidelines for Research and Evaluation (AGREE II) tool was used to appraise four English language asthma in pregnancy guidelines, published or updated between 2007 and 2016. The recommendations, range and level of evidence was analysed.

Results

Two of the four guidelines scored highly in most domains of the appraisal. Many of the recommendations made in the appraised guidelines were consistent. Due to the lack of randomised controlled trials involving pregnant women with asthma, most recommendations were evidenced by consensus and expert opinion rather than high quality meta-analysis, systematic reviews of randomised controlled trials.

Conclusion

The recommended antenatal asthma management was generally consistent among the guidelines but lacked clarity in some areas which then leave them open to interpretation. More randomised controlled trials involving pregnant women with asthma are required to fortify the recommendations made and asthma management guidelines should be included in Australian Antenatal Care Guidelines as they currently are not.  相似文献

Categorical perception, demonstrated as reduced discrimination of within‐category relative to between‐category differences in stimuli, has been found in a variety of perceptual domains in adults. To examine the development of categorical perception in the domain of facial expression processing, we used behavioral and event‐related potential (ERP) methods to assess discrimination of within‐category (happy‐happy) and between‐category (happy‐sad) differences in facial expressions in 7‐month‐old infants. Data from a visual paired‐comparison test and recordings of attention‐sensitive ERPs showed no discrimination of facial expressions in the within‐category condition, whereas reliable discrimination was observed in the between‐category condition. The results also showed that face‐sensitive ERPs over occipital‐temporal scalp (P400) were attenuated in the within‐category condition relative to the between‐category condition, suggesting a potential neural basis for the reduced within‐category sensitivity. Together, these results suggest that the neural systems underlying categorical representation of facial expressions emerge during the early stages of postnatal development, before acquisition of language.  相似文献

Analysis of a sample of 2084 child abuse referrals to the NSPCC Child Protection Helpline showed that in 10% a parent or carer was reported as having a mental health problem. Mothers were the parent affected in the majority of these cases. The mental health sample differed from the other referrals in an increased concern about emotional abuse and less about sexual abuse; greater levels of violence and discord between parents; and more agency involvement. Issues of potential labelling and therapeutic needs are discussed. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

From of Macroergonomic Analysis of Work were diagnosed the main ergonomics demands in a furniture company in the city of Cambé, Paraná. Through this method we could identify the most problematic points of the analyzed environment for posterior solutions of improvement with the objective of increasing the working and psychological quality of the employees, motivating their good performance and satisfaction.  相似文献

This paper examines the extent of and the mechanisms behind the penalty to motherhood in six European countries. Each country provides different levels of support for maternal employment allowing us to determine institutional effects on labour market outcome. While mothers tend to earn less than non-mothers, the penalty to motherhood is considerably lower in countries with policy support for working mothers. The paper establishes the United Kingdom and West Germany to have the least policy support for working mothers as well as the largest penalties to motherhood.
