一种提取多导体互连电磁参数的有效方法

利用区域分解法,将直线法和有限差分法相结合,计算了多层介质多导体互连的电容和电感矩阵。通过在纯介质区域使用直线法,导体所在区域使用有限差分法分别进行求解,充分发挥其各自的优越性。数值结果表明该计算方法有效,且计算时间与介质层的厚度无关。     

Ethnic Related Variations from the Cass Model of Homosexual Identity Formation: The Experiences of Two-Spirit,Lesbian and Gay Native Americans

Synthesis of current research with the self-stories of Native American two-spirit, lesbian and gay people suggests differences in social locations that may produce sexual orientation identity development processes absent from the current literature. We employed a modified form of grounded theory analysis to explore the identity experiences of six self-identified two-spirit, lesbian or gay Native Americans recounted during in-depth interviews. The resulting five themes are presented with quotes from participants for clarification and support, along with a discussion of their fit with the Cass Model of Homosexual Identity Development and interpersonal congruency theory. Results suggest two developmental pathways, one following the course of Cass' model and a second path notable for its absence of many of the key experiences specified by Cass.     

How to make head or tail of ‘bridging’ and ‘bonding’?: addressing the methodological ambiguity1

A distinction has recently been proposed between bridging (or encompassing) and bonding (or inward-looking) social networks. However, existing theoretical contributions remain vague as to the fundamental meaning of both concepts. As a consequence, two distinct interpretations have developed alongside each other. In the present paper, we employ data on voluntary association membership in Flanders to empirically illustrate that both approaches can lead to substantially different outcomes and therefore appear to tap into different dimensions of bridging versus bonding. These findings underline the problematic nature of the current conceptual ambiguity. We conclude that should the bridging/bonding distinction add meaningfully to our understanding of the external effects of social networks, it is essential to resolve the conceptual and methodological imprecision.
