Recent debate in Voluntas and elsewhere has paid a great deal of attention to the subject of mapping the nonprofit sector. However, very little attention has been paid to the ways in which the practice of mapping is a political mode of knowing and the ways in which knowing is governing. In this essay, we turn to critical theory and political anthropology in order to demonstrate how mapping as it is currently practiced is a mode of knowledge inquiry that facilitates statecraft. In light of these interdisciplinary perspectives, we wrestle with the implications of knowing—and thereby governing—voluntary collective organization in this manner. We conclude that this approach potentially disciplines the qualitative dimensions of democratic associational life and misrepresents the possibilities of social change.  相似文献

Mitochondrial defects have been related to obesity and prostate cancer. We investigated if Mexican–Mestizo men presenting this type of cancer, exhibited somatic mutations of ATP6 and/or ND3.Body mass index (BMI) was determined; the degree of prostate cancer aggressiveness was demarcated by the Gleason score. DNA from tumor tissue and from blood leukocytes was amplified by the polymerase chain reaction and ATP6 and ND3 were sequenced. We included 77 men: 20 had normal BMI, 38 were overweight and 19 had obesity; ages ranged from 52 to 83. After sequencing ATP6 and ND3, from DNA obtained from leukocytes and tumor tissue, we did not find any somatic mutations. All changes observed, in both genes, were polymorphisms. In ATP6 we identified, in six patients, two non-synonymous nucleotide changes and in ND3 we observed that twelve patients presented non-synonymous polymorphisms. To our knowledge, this constitutes the first report where the complete sequences of the ATP6 and ND3 have been analyzed in Mexican–Mestizo men with prostate cancer and diverse BMI. Our results differ with those reported in Caucasian populations, possibly due to ethnic differences.  相似文献

How can higher education programs engage students in building a shared commons to address inequalities and foster commitment to intergroup collaboration? Intergroup dialogue is one such possibility to provide forums for meaningful engagement among students from diverse backgrounds. Findings from field experiments at nine colleges and universities show that students in intergroup dialogues increased significantly more than counterparts in control groups and social science comparison groups in their critiques of inequality and their commitments to post-college action to redress inequalities. Further, students in intergroup dialogues rated the frequency of the core communication processes more highly than the social science comparison students. The communication processes help account for the greater increase in students’ critiques of inequality and commitment to post-college actions.  相似文献

In this commentary, we consider questions related to research integrity in data-intensive science and argue that there is no need to create a distinct category of misconduct that applies to deception related to processing, analyzing, or interpreting data. The best way to promote integrity in data-intensive science is to maintain a firm commitment to epistemological and ethical values, such as honesty, openness, transparency, and objectivity, which apply to all types of research, and to promote education, policy development, and scholarly debate concerning appropriate uses of statistics.  相似文献

Young children differ in their responses to failure, displaying mastery or helpless behavior patterns. We examine the moderating role of child temperament on the association between parent warmth/negativity and children's helpless responses to failure. Regarding temperament, we focus on tendencies to experience interest and sadness because they entail task engagement and withdrawal, respectively. We measured mother (n=150) expressions of positive and negative emotion during a teaching task, assessed temperament using LabTAB‐Preschool episodes, and coded helplessness during an impossible puzzle task. Maternal negative emotion during teaching was positively associated with helplessness, but only for children low in interest. Maternal warmth was negatively associated with helplessness, but only for children high in sadness; sadness did not moderate the relation between maternal negativity and helplessness. Findings provide support for parenting by temperament goodness‐of‐fit models and for a discrete emotions approach to temperament.  相似文献

This qualitative study was designed to explore decision-making processes used by directors of field education in social work programs in the USA. It is a follow-up to previous research showing the dilemmas that field directors face [specifics deleted to maintain the integrity of the review process]. We asked 22 field directors to explain how they would handle different dilemmas designed to simulate the kinds of issues that typically arise in field education. Analyses revealed that field directors use a four-dimensional decision-making process to address competing demands, employing a ‘good enough’ framework. The four dimensions include student learning, professional ethics, agency relationships, and administrative expectations.  相似文献

美国加利福尼亚州有这样一群"绿色妈妈",她们聚集在空气清新的客厅里,一边喝着红酒,一边说笑.她们的谈话很快就热烈起来--她们讨论的不是文学名著,也非名人八卦,而是各种可在家里落实的环保措施,比如抗菌洗手液的缺点、如何改造洗衣房以及在非能源使用高峰时段(晚7点后)只用冷水和生物降解洗涤剂洗衣服.  相似文献

Increasing aggregate concentration in the economy has increased attention to the issues surrounding the outside ownership of enterprises. Outside ownership entails both industrial diversification and various forms of conglomerate ownership and represents an important new direction for studies of economic sociology and labor market segmentation. The article shows that the influence of four measures of outside ownership on worker's earnings and tenure is largely, though not universally, negative. Outside ownership tends to suppress earnings otherwise accruing to workers in companies with high levels of unionization, rapid growth, and high profits. Workers' tenure is influenced negatively by some types of outside ownership but positively by others. Tenure is reduced in subsidiary firms and in industries predominately owned by other industries due to reduced union influence on job tenure in these settings. Average tenure is increased in companies that are spread across several industries. These findings provide little support for dual labor market theories and other economic theories that argue that workers benefit from the market power of their employing organizations. Instead, the findings provide support for theories that stress the dangers to workers' fates arising from the increasing dominance of financial management in economic decision making.  相似文献
