The goal in the present study was to understand the discourses that animate children’s talk about having a parent come out and how these discourses interplay to create meaning. Data were gathered through 20 in-depth interviews with adults who remembered a parent coming out to them as lesbian or gay. One discursive struggle animated the participants’ talk about their parents’ coming out: the discourse of lesbian and gay identity as wrong vs. the discourse of lesbian and gay identity as acceptable. Analysis of participants’ talk about their familial identities revealed a range of avenues for resisting the negative discourses regarding lesbian and gay identities. The findings highlight discursive power in participants’ talk about their familial identities and how participants organize the conflicting messages they receive in their culture and in relationships regarding family identities.  相似文献

The present study replicated and extended the Pelaez et al. (Journal of Applied Behavior Analysis 44:33–40, 2011) study, which examined the reinforcing effects of mothers’ contingent imitation of their infants’ vocalizations. Three infants aged 7–12 months who could vocalize sounds but not words participated with two caregivers for each infant (i.e., triads). During the intervention phase, the caregivers were asked to immediately imitate all vocalizations emitted by the child for a 3-min period. During the yoked control phase, the caregivers listened to an audio recording from the preceding condition and provided vocalizations non-contingently on the infants’ responses. The procedures yielded different results across participants; one infant emitted a higher frequency of vocalizations during the contingent imitation phases over the control phases, and the other two infants showed higher rates of responding during the control phases. However, all infants emitted more imitative return vocalizations during contingent reinforcement conditions compared with the yoked control condition.  相似文献

Social media continues to grow as a focus of social, organizational, and scholarly interest, yet there is little agreement as to what constitutes social media and how it can be effectively analyzed. We review various definitions of social media and note that much of the confusion regarding social media comes from conflation between social media types, platforms, and activities. To facilitate investigations of social media, we debunk common social media myths and review the relationship between social media and several prominent sociological concerns. We conclude by reflecting on directions for future research on social media.  相似文献

Welfare reform has had dramatic repercussions for millions of adults andchildren in the country. So far, the results of the "naturalexperiment" of welfare reform have shown both benefits and problems. Although welfare reform became law in 1996, there have been legislativerevisions and other policy changes aimed at making the law moreeffective and less punitive. The latest research indicates that welfare reform has had a major impact on the number of people who are receiving welfarebenefits but not on the income of former welfare recipients. Research also suggests that there are families who are suffering as a result of welfare reform. In this article, I discuss how welfare reform has evolved and theimplications for policy changes in the future.  相似文献

The relationship between work and marriage is well documented in dual-earner couples. Work-marital spillover patterns, however, have been understudied in single-earner couples. The current study extends the work-marital spillover literature by examining spillover patterns from individual experiences and self-care behaviors to the marital relationship over a period of 42 days in husband-earner and wife-earner couples. Results of pooled time-series regression analyses indicated individual experiences and self-care behaviors predicted marital processes for both employment groups. For self-care behaviors, however, different patterns emerged for employed and unemployed spouses. Results identify an important connection between energy depletion and marital processes, and highlight the role of a spouse’s own and the partner’s self-care behaviors, particularly for the employed spouse in single-earner couples.  相似文献

This study examined independent and interactive relations between the interparental relationship and maternal employment in predicting fathering within low‐income, Mexican American two‐parent families (N = 115). Interparental conflict was negatively related to quality fathering, and these relations were noted only for single‐earner families. The parenting alliance was positively related to quality fathering irrespective of maternal employment. Fathering was associated with lower levels of child depression and conduct problems. Results suggest that bolstering quality fathering is a useful avenue for improving child well‐being and that strengthening the interparental relationship can support quality fathering and child mental health within Mexican American families.  相似文献

The process of transformation of Bulgarian agriculture from a centrally controlled economy to a market-oriented economy is resulting in land reform, which will necessitate the immediate development and operation of land markets. On the one hand, the land reform is restoring land to those who owned it in the year 1947, or their heirs, who not only have very small and scattered holdings, but who often live in urban areas far from the claimed land and do not practice farming. On the other hand, farming is being changed by the liquidation of the former collective farms and the emergence of privately managed farms and new forms of co-operatives. These new operating units may or may not have their own land claims, but in most cases, do not have immediate access to sufficient land for adequately sized operations. Without land market institutions for information, contracting land use, and enforcement of contractual rights, the transaction costs of bringing the suppliers of land together with those demanding land will result in unused land and distorted agricultural activity. The paper explores both the formation of institutions and the evidence of transactions, as well as the possible impacts on farming.  相似文献

To successfully acquire language, infants must be able to track multiple levels of regularities in the input. In many cases, regularities only emerge after some learning has already occurred. For example, the grammatical relationships between words are only evident once the words have been segmented from continuous speech. To ask whether infants can engage in this type of learning process, 12‐month‐old infants in 2 experiments were familiarized with multiword utterances synthesized as continuous speech. The words in the utterances were ordered based on a simple finite‐state grammar. Following exposure, infants were tested on novel grammatical and ungrammatical sentences. The results indicate that the infants were able to perform 2 statistical learning tasks in sequence: first segmenting the words from continuous speech, and subsequently discovering the permissible orderings of the words. Given a single set of input, infants were able to acquire multiple levels of structure, suggesting that multiple levels of representation (initially syllable‐level combinations, subsequently word‐level combinations) can emerge during the course of learning.  相似文献
