Siblings who have suffered severe trauma and disrupted attachment relate to one another in ways that interfere with individual development, the chance to benefit from connections with adults, the establishment of healthy sibling relationships, and the working through of traumatic experiences. The authors use case examples to illustrate four distinct sibling patterns: absent, adult lockout, half and half, and trauma shield. The authors highlight the importance of recognizing these types and then varying the therapist's treatment stance to pursue five goals. These include suspending problematic sibling relationships to create room for bonding with caring adults, transferring attachment behaviors and impulses to a receptive adult, resuming healthy individual development, forming more adaptive sibling connections, and expressing shared traumatic content.  相似文献

高技术产业在推动产业升级和创新驱动方面具有重要带动作用。以长江经济带11省市高技术产业为研究对象,运用空间杜宾模型,选取2006—2015年面板数据,研究创新要素集聚及其对高技术产业的空间溢出效应。研究表明:创新要素集聚的非均衡分布特征明显;除资本投入和劳动力投入外,创新要素集聚对高技术产业发展的促进作用最为显著;创新要素集聚在省域间的溢出效应大于省域内的溢出效应。  相似文献

This research project explores the relationship between social anxiety and appearance management behaviors (AMB), including both routine and non-routine, among gay and straight men and women. Prior research had found links between AMB and stress (Reilly & Rudd, 2002), stress and (perceived) discrimination (Lee, 1997; Savin-Williams, 1994), and sexual orientation and weight (Brand, Rothblum, & Solom, 1992). An argument is made that links stress with AMB using the foundation of Social Comparison Theory (Festinger, 1954) as a guide. Research questions investigated were: (1) Is there a correlation between stress and AMB; (2) Is there a significant difference between body mass indices of men and women of differing sexual orientations; (3) How do AMB differ between those with gay and straight orientations; and (4) How do AMB differ between men and women? Using a survey design, a questionnaire was posted on the Internet. Measures included the Rudd/Lennon Appearance Management Scale of Routine and Risky Behaviors and the Liebowitz Social Anxiety Scale. A total of 365 usable forms were completed. Results show that social anxiety is positively correlated with non-routine AMB, or behaviors that carry some risk. Gay and straight participants differed on the routine AMB they practiced. Men and women differed on the non-routine or risky AMB they practiced or would consider practicing. Implications are discussed and further research is suggested.  相似文献

The technical characteristics of electricity generation and transmission have implications for the way in which economic principles are adapted to evaluate pricing and regulation issues in electricity markets. In particular, there is an externality associated with the way in which electricity flows in networks because of Kirchoff's laws. In this paper, a mathematical programming model is presented that simulates a competitive electricity market, based on the spatial-intertemporal equilibrium models pioneered by Takayama and Judge (1971). The model is used to simulate the operation of a hypothetical electricity market, illustrating some of the issues arising from the network externality.  相似文献

Within democratic political systems the activities of organized groups, striving to influence government decisions on matters affecting their particular interests, are widely recognized as a significant element in the political process. Members of the nursing profession in Queensland have sought to obtain concessions from governments. The tactics used and the degree of success achieved by nurses, when acting as a pressure group, are described. The organization which represents the interests of Queensland nurses is the state branch of the Royal Australian Nursing Federation (RANF). Until the 1960s the organization did not utilize pressure group activities to any great extent, being satisfied to accept the status quo in matters of nurse training and registration. In the 1960s the RANF decided to take the initiative in seeking changes in the relevant legislation. Initially, the campaign mounted by the organization to achieve its objectives revealed a lack of acceptance by the association of the full implications of pressure group tactics. In the later 1960s when there was more awareness of the fact that the organization was acting as a pressure group, greater success was achieved.  相似文献

Academic interest in official systems of racial and ethnic classification has grown in recent years, but most research on such census categories has been limited to small case studies or regional surveys. In contrast, this article analyzes a uniquely global data set compiled by the United Nations Statistical Division to survey the approaches to ethnic enumeration taken in 141 countries. The motives for this analysis combine theoretical, applied, and policy objectives. I find that 63% of the national censuses studied incorporate some form of ethnic enumeration, but their question and answer formats vary along several dimensions that betray diverse conceptualizations of ethnicity (for example, as “race” or “nationality”). Moreover, these formats follow notably regional patterns. Nonetheless, the variety of approaches can be grouped into a basic taxonomy of ethnic classification approaches, suggesting greater commonality in worldwide manifestations of the ethnicity concept than some have recognized.

The entropy measure H=−σpi log pi is being used with increasing frequency in the analysis of business and economic data. It is, however, simply another measure of dispersion which can be related to the moments of the probability function. Its virtues stem from its decomposition and interpretative properties. This paper surveys the uses to which the measure has been put in the literature, and discusses whether its use has been appropriate and innovative.  相似文献
