美国竞选财政制度初探

美国竞选财政制度是美国政治制度中争议最多的问题之一。由于利益集团政策参与的需求和竞选人竞选的需要 ,美国的竞选捐赠日益加剧 ,捐赠规模日趋膨胀 ,并在一定程度上导致了决策过程中利益代表性的偏差。由此 ,美国早期的法律就对利益集团的竞选捐赠进行限制 ,2 0世纪 4 0年代以来 ,美国关于竞选财政制度改革的立法不断。但改革遇到利益需求和关于合宪性问题等种种障碍 ,步履维艰。美国政治中的这一两难状况是其政治体制所使然 ,有关竞选财政制度改革的争论仍将继续下去。     

“拯救”新闻业的技术方案何以失灵?--区块链新闻初创公司“可感知创新属性”分析

区块链技术在范式创新的意义上激发了对新闻业前景的乐观想象,区块链新闻初创公司作为“颠覆性创新者”,形成了与成熟媒体机构完全不同的创新路径。本文以创新扩散理论中的“可感知创新属性”为分析框架,考察了初创公司Civil的创新历程及其潜在采纳者在决策中可能感知的综合信息氛围。研究表明,Civil在商业和专业方面带来相对优势的感知是模糊的,甚至是高风险的;激进的创业文化与遵循制度化、常规化业务逻辑的传统新闻业存在相容性上的障碍;过于复杂的运行机制和购买流程大大降低了创新的可试验性和可观察性,这些因素共同构成了潜在采纳者对其创新属性的负面感知,进而使这种强调采纳决策相互依赖性的交互式创新趋于失败。     

Girls’ “New Femininity” Refusals and “Good Girl” Recuperations in Soap Talk

The “new femininities” produced in postfeminist media confront girls with complex and challenging subjectivities that reach into the spaces where girls engage in their own productions of self. Feminist scholarship has interrogated and critiqued the “girl” produced in postfeminist popular culture texts, highlighting her internal contradictions and often problematic re/production within the heterosexual matrix. Yet, despite an intensified focus on girls featured in popular culture, the ways that girls themselves make sense of the “girl” in contemporary femininity texts has been relatively neglected. Viewing girls' sense-making of femininity in popular culture texts as crucial in the process of their subjectivity or self-production, in this paper we examine pre-teen girls' negotiations of femininity through their talk about Scarlett, a main teen girl character in a New Zealand soap drama. Our analyses and discussion focus on girls' management of the contradictory and regulatory productions of femininity in the text, in particular the often classed conditions under which girls recuperate the “good girl” discourse to refuse the regulatory femininities inside the heterosexual matrix. We suggest that an absence of empowering discourses outside of postfeminism's sexual empowerment limits girls' resources for critiquing and challenging regulatory femininities, “new” and “traditional.”     

Inferences on regression coefficients in a regression model under heteroscedasticity and robustness with respect to departure from normality

In this paper we consider a simple linear regression model under heteroscedasticity and nonnormality. A statistical test for testing the regression coefficient is then derived by assuming normality for the random disturbances and by applying Welch's method. Some Monte Carlo studies are generated for assessing robustness of this test. By combining Tiku's robust procedure with the new test, a robust but more powerful test is developed.     

从美国金融危机看金融安全问题

美国金融危机始于2007年夏季，之后迅速蔓延到世界各主要经济体，对各国金融安全和全球经济发展带来了威胁和挑战。为了维护金融的安全与稳定，各国不但要提高对金融安全问题的重视程度、增强对金融创新风险防范的能力、完善金融监管体系，还要加强国际区域金融合作，并为构建新型的国际金融体系作出不懈努力。

On square ordinal contingency tables: a comparison of social class and income mobility for the same individuals

Summary.  Square contingency tables with matching ordinal rows and columns arise in particular as empirical transition matrices and the paper considers these in the context of social class and income mobility tables. Such tables relate the socio-economic position of parents to the socio-economic position of their child in adulthood. The level of association between parental and child socio-economic position is taken as a measure of mobility. Several approaches to analysis are described and illustrated by UK data in which interest focuses on comparisons of social class and income mobility tables that are derived from the same individuals. Account is taken of the use of the same individuals in the two tables. Additionally comparisons over time are considered.
