论中国岩画的取象规则

取象是岩画制象的首要步骤。中国岩画在取象中显示出了几大原则。第一是简化原则。它包括投影轮廓技法、局部代整体技法和抽象化技法。第二是最大轮廓化原则，指最大面积地截取轮廓。这在早期艺术中时常出现。第三是局部凸现原则。它在中国岩画中表现为形体的凸现与位置的凸现两种形式。第四是多点平视原则。它表现了岩画缺乏背景衬托，属于触觉绘画的特征。这些原则的综合运用代表着原始岩画的取象特征，显示了原始先民的取象思维。     

On the efficiency of two-stage and three-stage least squares estimators

This paper utilizes the results of Kruskal (1968), Zyskind (1967), and more recently Milliken and Albohali (1984) to derive a simple necessary and sufficient condition for 3SLS to be equivalent to 2SLS. This condition depends upon the inverse of the variance:covariance matrix of the disturbances, and the set of second stage regressors of each structural equation. More importantly, this condition should prove useful for econometric students and provides an easy method for checking sufficiency.

Perceived social standing among Asian immigrants in the US: Do reasons for immigration matter?

We investigate the association between a subjective measure of social status and the reasons for immigration among Asian immigrants in the US. We use data from the National Latino and Asian American Study to test several hypotheses about this association. Our analyses show the positive effect on perceived social standing of migrating for better education, the negative effect of migrating to seek employment, and the negative impact of refugee status. Migrating for family reunification can be associated with various circumstances, which lead to differing outcomes. The results suggest that the notion that immigrants arrive in the US with limited resources and few skills and move slowly up the socioeconomic ladder must be reassessed in light of the complex social context and factors such as ethnicity, gender, divergent immigration paths, and a range of associated circumstances.

The Symbolic Dilemmas of Suburban Poverty: Challenges and Opportunities Posed by Variations in the Contours of Suburban Poverty1

Poverty has increased significantly in U.S. suburbs since the 1990s. What we know about suburban poverty is largely limited to demographic and economic information. Building off the organizational perspective approach, I use in‐depth interviews with nonprofit, antipoverty organizations in eight Pennsylvania suburbs to better understand the suburban poverty experience. My focus is on how organizations compete for external resources. By working directly with the poverty problem while also working in broader metropolitan political and economic fields of decision making, this “middleman” role ( Marwell, 2007 ) gives us insights into contemporary poverty dynamics for suburbs. I find that how suburban organizational leaders perceive the challenges they face, and what strategies they adopt to confront such difficulties, revolves around symbolic dilemmas posed by the history, distribution, and politics of poverty in the suburbs. Symbolic dilemmas cluster around three different situational contexts of poverty in the suburbs. I use this to develop a three‐part typology of suburban poverty: symbiotic suburbs, skeletal suburbs, and overshadowed suburbs. This typology has implications for future research and for policymakers interested in developing tools to appropriately address this pressing issue.     

略论限度观

限度对于人们生存和发展具有重要的指导意义。为更好地适应时代发展要求，人们应该确立科学合理的限度观：必须恪守“最低限度”，应该追求“最大限度”，务必防止“无意过度”，可以倡导“超越限度”。确立科学合理限度观体现了科学发展的精神，有利于和谐社会的构建，有益于社会主客体的发展。人们要在实践和感悟中去寻求、把握和发展限度。科学合理限度观的确立，必须坚持求真务实、持续发展和公正发展等实践原则。
