Relations between grandmother and partner involvement (coresidence, social support, child care) and Puerto Rican adolescent mothers' parenting behaviors were examined. Few associations between grandmother involvement and behavior emerged, and these were moderated by coresidence. In contrast, partner involvement showed a number of significant (positive) direct and moderated relations with behavior. For both providers, the direction of the relations between social support and behavior during teaching was the opposite depending on coresidence: Greater social support was related to the display of more positive behavior among coresiding mothers but to less competent behavior among non‐coresiding mothers. The relations between child care support and behavior differed across providers. For grandmothers, greater child care was related to less positive behavior during teaching among coresiding mothers but to more competent behavior among non‐coresiding mothers. For partners, greater child care was more strongly related to positive behavior during play among non‐coresiding than coresiding mothers. Results are discussed in light of Latino cultural values, developmental issues, and implications for intervention. 相似文献

The aim of this study was to determine the psychometric properties of a short version of the Fisher Divorce Adjustment Scale (FDAS–SF; Fisher, 1978) in the Chilean context. Participants were 260 individuals who were divorced or separated. The FDAS–SF included 22 of the original 100 items, and its factorial structure was evaluated using exploratory and confirmatory factor analysis. Instead of the 6 original subscales proposed by its author, the structure that showed the best fit to the data was composed of 5 subscales: self-worth, disentanglement from the ex-partner, anger, grief, and social trust. The social self-worth subscale was excluded. Reliability analyses revealed good internal consistency of the subscales and adequate convergent validity with depression, anxiety, stress, and life satisfaction. Given the psychometric properties of this short version, it can be concluded that the FDAS–SF can be used in the Chilean context to evaluate the adjustment to divorce and separation. 相似文献

Qualitative Sociology - In the past, ethnographers often presented themselves in the classic hero frame, where they appeared authoritative and calm. Recent ethnographers, though, reveal hardship... 相似文献

A transparency movement has begun urging researchers to publicize their data in order to ease replication and accountability. Some ethnographers have also begun arguing that researchers should unmask, or fully disclose, field sites and participant identities in order to replicate studies, verify accounts, and monitor social phenomena over time. However, for ethnographers studying violence and crime, full transparency or unmasking can get an ethnographer harmed. Thus, I broaden the unmasking/masking discussion by arguing for partial disclosures in dangerous research. To do so, I provide examples from my previous drug market ethnography and my ongoing gang research. I then propose safer ways to disclose field sites and participants, mainly through the following: semibiographical disclosure, where the ethnographer strategically omits some data in otherwise rich biographical portraits; through partial spatial disclosures, where the ethnographer reveals the field site's general area; and through invitational disclosure, where the ethnographer invites outsiders to meet participants in the field. 相似文献

In this article, we evaluate ethnic solidarity and the vote in Chile with reference to the Mapuche, the largest and most traditional ethnic group in the country. We use electoral data from the mayoral elections of 2012, drawn from all the municipalities of the Araucanía, the region with the largest percentage of Mapuche population. Using a multi-level linear regression model and controlling for poverty and rurality, we found that Mapuche candidates, regardless of their political orientation, were indeed more successful than non-Mapuche candidates in areas with the greatest concentration of Mapuche voters. Additionally, we used results from an unpublished opinion survey conducted in three municipalities of the Araucanía. We concluded that after controlling for other variables ethnic solidarity prevails as a robust predictor of electoral behaviour, albeit more strongly in rural areas than urban ones. The Chilean case, moreover, is useful for studying the strategies used by the traditional parties that promote this solidarity – that is, by presenting candidates with Mapuche surnames in their lists. 相似文献

A successful experience to train power producers on pool-based electricity markets presented. Trainees are arranged in groups and assigned, at random, a set of generators. They play the role of power producers and compete against each other with the target of maximizing their own profits. They have to bid in terms of price and quantity to try to sell energy to the consumers through the market. The trainer plays the role of the market operator. A market simulator and a computer communication network make it possible to simulate the actual functioning of a pool-based electricity market. The simulator is based on the widely used software package MATLAB, and a computer communication net, which can be replaced by the WWW. 相似文献
