When children act to involve mothers in positive interaction, they influence the amount, timing, and content of parent–child exchanges. By assessing children's smiling and positive initiation, we examined child behaviors that function to create positive interaction. In a non-clinical North American sample of 103 mothers and their 14- to 27-month-olds, we observed that children attempted to connect positively with mothers (1) more with age, (2) more frequently and quickly immediately after mothers were responsive, (3) more with mothers who were generally supportive, and (4) more with mothers low in depressive symptoms. When mothers were high in depressive symptoms, age-related increases in smiling and positive initiation were absent. Findings demonstrate the importance of maternal depression and responsiveness to child behaviors that involve mothers in ongoing activity. They suggest that both immediate cues and children's stored knowledge related to how mothers will respond may regulate children's positive connecting behaviors.  相似文献

Sources of power children use in sibling conflict during early and middle childhood were examined according to French and Raven's typology of power. Participants included 66 dyads with an older (M = 81.8 months, SD = 14.48 months) and younger (M = 56.2 months, SD = 13.03 months) sibling. Data based upon naturalistic observations were coded for conflict issues (object, procedure, and information), power types (coercive, information, and legitimate), power effectiveness (attempts and successes), and resolutions (win/lose and compromise). Siblings used coercive power in object issues and information power in procedural issues. Whereas younger siblings used legitimate power in procedural and object issues including win/lose and compromise outcomes, older siblings used coercive power in win/lose resolutions. Siblings did not differ in their effectiveness of power, but they were most effective when coercive power was employed. Findings are discussed in light of power theory and the development of conflict management skills.  相似文献

This study examines the distinction between power imbalance and mutual dependence to better understand how NGOs manage resource dependencies in their relationships with civil society partners. The NGO leaders we interviewed emphasized mutual dependence in the relationships they developed with other NGOs regarding access to financial and information resources. In contrast, discourse about their relationships with IGOs focused on the acquisition of legitimacy and access, and was dominated by power imbalance. NGOs were largely accepting of both forms of dependence in pursuit of the community’s shared goals and for the greater good of constituents. Our finding that NGOs refrain from terminating suboptimal relationships also reflects the extent to which mutual dependence governs NGOs partnering strategies.  相似文献

A mail questionnaire methodology was utilized to provide baseline data on consumers' reactions to the Canadian Oil Substitution Program (COSP). COSP is a major financial incentive, operated by the Canadian government, designed to stimulate conversions of oil-fired home hearing systems to alternative energy sources.The results provide a snapshot of consumer reactions one year after the COSP incentive was first introduced. Specific results include the motives for and barriers to off-oil conversion; the importance of COSP, relative to other conversion motives; and the size and characteristics of the oil-user group who are resistant to converting off-oil heating. Implications for program management and directions for future research are discussed.  相似文献

The computerisation of membership lists offers considerable scope for postal surveys of trade unionists. However, faith in the new technology can give rise to the illusion of increased accuracy. Yet, the computerised data bases, while undoubtedly quicker and easier to use, may be no more accurate than their manual predecessors and samples drawn from them can result in misleading response rates. Therefore, with reference to a specific case study of a major trade union, we argue that researchers should seek to establish empirically the probable error in their lists with a view to constructing realistic ‘benchmarks’. Then, these substantial new resources can provide a solid basis for worthwhile research.  相似文献

We find that, in a linear model, the James–Stein estimator, which dominates the maximum-likelihood estimator in terms of its in-sample prediction error, can perform poorly compared to the maximum-likelihood estimator in out-of-sample prediction. We give a detailed analysis of this phenomenon and discuss its implications. When evaluating the predictive performance of estimators, we treat the regressor matrix in the training data as fixed, i.e., we condition on the design variables. Our findings contrast those obtained by Baranchik (1973 Baranchik , A. J. ( 1973 ). Inadmissibility of maximum likelihood estimators in some multiple regression problems with three or more independent variables . Ann. Statist. 1 ( 2 ): 312321 .[Crossref], [Web of Science ®] [Google Scholar]) and, more recently, by Dicker (2012 Dicker , L. ( 2012 ). Dense signals, linear estimators, and out-of-sample prediction for high-dimensional linear models. arXiv:1102.2952 [math.ST].  [Google Scholar]) in an unconditional performance evaluation.  相似文献

渤海与日本交聘中“高丽国”的辨析   总被引:1,自引:0,他引:1  
渤海与日本建立交聘关系及其努力保持和发展与日本的交聘关系 ,是出于渤海的政治、经济利益的需求。在交聘中 ,渤海统治者的某些做法使日本一度产生渤海是高句丽的后继国的误解 ,日本出于自身利益曾在一段时期内改称渤海为“高丽”。事实上 ,渤海从未明确表示过自己是高句丽的继承国 ,所谓“渤海对高句丽的继承意识”也是一种主观臆想的错误看法  相似文献

This paper aims to uncover gendered interpretations of various kinds of suicidal behaviour. Its empirical basis is focus group discussions with a range of young people, including users of social work services. In support of Canetto's research, the authors found some of the young people to be associating ‘successful’ suicides with masculinity and ‘failed’ suicide attempts with femininity. These feminized suicide attempts were subject to some fairly pejorative interpretations, such as being motivated by revenge or manipulation. There was no particular pattern of viewpoints in terms of the sex of respondents. The implications of these findings for social work are discussed.  相似文献
