A Graphical Tool for Interpreting Regression Coefficients of Trinomial Logit Models

Multinomial logit (also termed multi-logit) models permit the analysis of the statistical relation between a categorical response variable and a set of explicative variables (called covariates or regressors). Although multinomial logit is widely used in both the social and economic sciences, the interpretation of regression coefficients may be tricky, as the effect of covariates on the probability distribution of the response variable is nonconstant and difficult to quantify. The ternary plots illustrated in this article aim at facilitating the interpretation of regression coefficients and permit the effect of covariates (either singularly or jointly considered) on the probability distribution of the dependent variable to be quantified. Ternary plots can be drawn both for ordered and for unordered categorical dependent variables, when the number of possible outcomes equals three (trinomial response variable); these plots allow not only to represent the covariate effects over the whole parameter space of the dependent variable but also to compare the covariate effects of any given individual profile. The method is illustrated and discussed through analysis of a dataset concerning the transition of master’s graduates of the University of Trento (Italy) from university to employment.     

The context of employment discrimination: interpreting the findings of a field experiment

Although field experiments have documented the contemporary relevance of discrimination in employment, theories developed to explain the dynamics of differential treatment cannot account for differences across organizational and institutional contexts. In this article, I address this shortcoming by presenting the main empirical findings from a multi‐method research project, in which a field experiment of ethnic discrimination in the Norwegian labour market was complemented with forty‐two in‐depth interviews with employers who were observed in the first stage of the study. While the experimental data support earlier findings in documenting that ethnic discrimination indeed takes place, the qualitative material suggests that theorizing in the field experiment literature have been too concerned with individual and intra‐psychic explanations. Discriminatory outcomes in employment processes seems to be more dependent on contextual factors such as the number of applications received, whether requirements are specified, and the degree to which recruitment procedures are formalized. I argue that different contexts of employment provide different opportunity structures for discrimination, a finding with important theoretical and methodological implications.

论奉天当局对朝鲜移民开发水田的政策

朝鲜移民的水田开发，促进了东北地区农业经济的发展。开始之初，奉天当局及东北地区官民对开发水田的朝鲜垦民采取了积极鼓励的政策。《满蒙条约》签订之后，为了控制朝鲜移民的迁入和抵制日本帝国主义利用朝鲜移民对中国的侵略，奉天当局对朝鲜移民采取了限制、取缔的政策，严厉禁止朝鲜移民的土地所有权。     

高速SDRAM控制器设计的FPGA实现

同步动态存储器(SDRAM)控制器通常用有限状态机实现,对于一般的设计方法,由于状态数量多,状态转换通常伴随大的组合逻辑而影响运行速度,因此,SDRAM控制器的速度限制了SDRAM存储器的访问速度。该文从结构优化入手来优化方法,利用状态机分解的思想将大型SDRAM控制状态机用若干小的子状态机实现,达到简化逻辑的目的,不仅提高了速度还节省了资源,对该类大型SDRAM控制器的实现有一定参考意义。     

三螺旋创新模式的理论探讨

基于非线性网状创新模型提出的“三螺旋场”和“三螺旋循环”概念进一步推进了三螺旋创新模式的理论研究。三螺旋场概念旨在解释在大学、产业和政府三股螺旋之间存在的相对独立和彼此作用的本质，说明三螺旋的生成原理、静态表现和动态演化特征。三螺旋的生成原理在于创新过程的非线性本质和多主体特征，静态表现为“内核外场模型”，而动态演化过程则在于纵向进化和横向循环。发生在三股螺旋之间的三螺旋循环揭示了在大学、产业和政府之间以人员、信息和产品流动为特征的相互作用和运行机制。     

法与非政治公共领域制度间博弈对社会结构之影响

本文是在《中国社会结构变迁与转型的动因探索:通过社会行动的法与非政治公共领域的关系解读》一文的基础上所做的更进一步的研究,仍以非政治公共领域的主体行动为支点,在非政治公共领域的制度与法律之间搭建桥梁,并通过主体行动实践在这几者要素之间的博弈分析,揭示非政治公共领域主体是如何通过行动实践促使社会结构变迁和转型的,从而进一步探索中国社会结构变迁与转型之潜在动因,并试图对社会行动理论做更深入的诠释和研究。     

口语教学中的文化教学

语言与文化相互依赖密不可分,语言学习离不开文化积累。本文从文化、语言、交际的内涵以及三者的关系为出发点,阐述了中西文化体现在语言运用上的差异,提出了将文化融于口语教学中的必要性和具体的实施方法。

俄语交际失误产生的两个重要原因

交际失误现象在非正式交际中是不可避免的，在本质上属于生动的、自发的交流。到目前为止，语言学文献中很少讨论言语相互作用而导致的交际不顺畅，以及不成功交际中产生的交流失误。现代语言学对交际失误的系统研究刚刚开始。引起交际失误的语言学因素包括编码错误和评价行为特征，对交际失误产生的原因进行研究，很有必要。
