This article explores under what conditions an agent can derive a transitive all-things-considered preference from a plurality of non-comparable objectives, values or judgements mirroring her plural identity. In contrast to existing contributions, the multiple values are reflected by partial (viz. incomplete) orderings. It is shown that a slight modification of the conditions employed by Arrow implies a spread of the dictate of one identity to its ‘incomplete parts’. The second result reveals that if one requires the decision making power to be spread a bit more equally across the various parts of a person’s identity, then even the derivation of an acyclic all-things-considered preference is rendered impossible. A third result shows that requiring some minimal consistency among a person’s plural identities, introduced via a domain restriction, allows the avoidance of the highlighted impossibilities.  相似文献

Children's conscience, including the ability to experience guilt and engage in rule‐compatible behavior, develops across early childhood. The current study investigated whether within‐family variation in children's baseline respiratory sinus arrhythmia (RSA) and sibling conflict behavior were associated with individual differences in children's guilt and internalized conduct. Between‐family differences across sibling dyad gender compositions were also examined. A within‐family design that included 70 families with two siblings between the ages of 2 and 5 was utilized. Children's baseline RSA was measured while sitting quietly with their family. Mothers and fathers completed questionnaires that assessed siblings’ conflict behavior, guilt, and internalized conduct. Older siblings had higher levels of guilt and internalized conduct than younger siblings. Results from actor‐partner interdependence models indicated that there were no direct effects of children's baseline RSA. The interaction effects approached significance (p's ≤ .08) suggesting that older siblings’ conflict moderated the association between older siblings’ baseline RSA and both older and younger siblings’ guilt. In contrast, older siblings’ conflict was positively associated with older and younger siblings’ internalized conduct. Guilt and internalized conduct also differed for older and younger siblings in different dyad gender compositions. The results underscore the need for greater clarity regarding the function that siblings serve in promoting children's moral development during early childhood.  相似文献

This study considers key value differences between leaders of two types of social ventures: for-profit social benefit corporations and nonprofit organizations. The research question asks to what degree the value sets of leaders of benefit corporations are congruent with those of similarly situated individuals in nonprofit organizations. The results show the values of leaders working in benefit corporations and nonprofit organizations are in many ways aligned, but there are notable statistical differences. A sectoral association of values is also present with employees in both types of organization, especially when the previous work experience of employees is considered.  相似文献

Spanish-speaking and culturally sensitive social workers are in high demand throughout the country to work with Latino clients. Latinos currently represent about 11% of active social workers, limiting the capacity of social work to effectively address the needs of the Latino population. Despite this shortage, little attention has been paid to the recruitment and retention of Latinos in social work. This article presents a case study that examines a BSW program accredited by the Council on Social Work Education, at a bilingual, private college where 90% of students self-identify as Latinos. It details how the BSW program builds on the students’ community cultural wealth to ensure continued recruitment and retention of Latino students. Implications for social work education are discussed.  相似文献

The costs for rent and utilities account for the largest share of living expenses, yet these two critical dimensions of material hardship have seldom been examined concurrently in population-based studies. This paper employs multivariate statistical analysis using American Community Survey data to demonstrate the relative risk ratio of low-income renter-occupied households with children experiencing ‘rent burden', ‘energy insecurity', or a ‘double burden’ as opposed to no burden. Findings suggest that low-income households are more likely to experience these economic hardships in general but that specific groups are disproportionately burdened in different ways. For instance, whereas immigrants are more likely to experience rental burden, they are less likely to experience energy insecurity and are also spared from the double burden. In contrast, native-born African Americans are more likely than all other groups to experience the double burden. These results may be driven by the housing stock available to certain groups due to racial residential segregation, decisions regarding the quality of housing low-income householders are able to afford, as well as home-country values, such as modest living and energy conservation practices, among immigrant families. This paper also points to important policy gaps in safety net benefits related to housing and energy targeting low-income households.  相似文献

This paper uses longitudinal data from the Philippines to analyze determinants of children’s time allocation. The estimation method takes into account both the simultaneity of time use decisions, by allowing for correlation of residuals across time uses, and unobservable family heterogeneity, through the inclusion of household fixed effects. Importantly, this improved estimation method leads to different results than when applying the methods previously used in the literature. Girls suffer significantly from the absence of their mother with a reduction in time spent in school that is equivalent to dropping out completely. This effect is substantially larger when controlling for household unobservables than when not. Boys increase time spent working on market related activities in response to an absent father, although this time appears to come out of leisure rather than school or doing household chores. Land ownership substantially increase the time boys spend on school activities, whereas renting land reduces the time girls spend on school. Finally, there does not appear to be a substantial trade-off between time spent on school and work, either in the market or at home.  相似文献

In this article I explore a methodology of storytelling as a means of bringing together research around autism and childhood in a new way, as a site of the embodied becoming of autism and childhood. Through reflection on an ethnographic story of embodiment, the body is explored as a site of knowledge production that contests its dominantly storied subjectivation as a ‘disordered’ child. Storytelling is used to experiment with a line of flight from the autistic-child-research assemblage into new spaces of potential and possibility where the becomings of bodies within the collision of autism and childhood can be celebrated.  相似文献

We discuss qualitative and quantitative research findings from a study exploring the benefits and effectiveness of a 12-week arts-based mindfulness group program for vulnerable children (children who were involved with the child welfare or mental health systems and experienced a variety of challenges). Using post-group individual interviews with children/guardians, and pre and post-intervention self-report data (using the Piers-Harris Children’s Self-Concept Scale and the Resiliency Scales for Children and Adolescents), we hypothesized that children would have improved resilience and self-concept after having completed the program. Interpretive thematic qualitative analysis was conducted using transcribed interview data collected from 47 children (30 girls and 17 boys with a mean age of 10.38 years). The perceived benefits of participating in the group included improved (a) emotion regulation, (b) mood, (c) coping/social skills, (d) confidence and self-esteem, (e) empathy, and (f) ability to pay attention and focus. The quantitative analysis used self-report data from 77 children (43 girls and 34 boys with a mean age of 10.34 years). A repeated measures MANOVA was used to examine changes across the intervention period. Our hypothesis that children would have better scores on self-concept after having completed the program was partially supported and this result reflected the perceived improvements derived from the qualitative analysis. The hypothesis that resilience would improve post-group was not supported. Using these promising results, we discuss how strengths-based and arts-based mindfulness group methods may be effective in engaging vulnerable children in a beneficial helping process.  相似文献

The amygdala is essential for processing emotions, including the processing of aversive faces. The aim of this multimethodological study was to relate the amygdala reactivity of students (= 88) toward teachers’ fearful and angry faces, to students’ relationship with their teachers. Furthermore, students’ neural responses during the perception of teachers’ faces were tested as predictors of test anxiety (controlling for neuroticism as a potential trait anxiety effect). Multiple regression analysis revealed that students reporting high‐quality teacher–student relationships showed stronger amygdala activity toward fearful faces, which was related to worry. Furthermore, students with high levels of neuroticism tended to perceive their teachers as motivators and showed higher amygdala activity toward angry faces, which was related to the measures of emotionality.  相似文献
