从不同价值领域看中国传统价值观

对不同价值领域间关系的定位与评判是反映人们价值观的一个重要维度。中国传统价值观在道德价值与非道德价值领域、家庭生活与政治生活领域、道德价值与超道德的神圣价值领域、不同文化领域之间的关系上都表现出一元论的倾向。我们应立足于领域分离、价值多元的现代背景对其进行反思 ,以构建有中国特色的价值观念体系     

俄汉语认知域中的转喻与隐喻连续体现象——以俄汉语“手”的认知为例

语言中的基本范畴词是人们认识世莽的基础，在此基础上人们通过转喻、隐喻来认知更抽象的概念和事物。俄汉语中的“рука——手”同属基本范畴词，具有很强的转喻：隐喻能力。通过手部动作认知、情绪认知、场景认知、权势认知、身体结构认知等方面研究俄汉语认知域中转喻与隐喻的交互作用在词汇层面的连续体关系，将有助于从实证的角度对比分析俄汉语转喻和隐喻思维模式的异同，探求造成两个民族认知差异的文化因素。

Math-oriented fields of study and the race gap in graduation likelihoods at elite colleges

This study examines the relationship between chosen field of study and the race gap in college completion among students at elite colleges. Fields of study are characterized by varying institutional arrangements, which impact the academic performance of students in higher education. If the effect of fields on graduation likelihoods is unequal across racial groups, then this may account for part of the overall race gap in college completion. Results from a large sample of students attending elite colleges confirm that fields of study influence the graduation likelihoods of all students, above and beyond factors such as students’ academic and social backgrounds. This effect, however, is asymmetrical: relative to white students, the negative effect of the institutional arrangements of math-oriented fields on graduation likelihood is greater for black students. Therefore, the race gap is larger within math-oriented fields than in other fields, which contributes to the overall race gap in graduation likelihoods at these selective colleges. These results indicate that a nontrivial share of the race gap in college completion is generated after matriculation, by the environments that students encounter in college. Consequently, policy interventions that target field of study environments can substantially mitigate racial disparities in college graduation rates.     

Asymptotic behaviour of binned kernel density estimators for locally non-stationary random fields

We investigate the asymptotic behaviour of binned kernel density estimators for dependent and locally non-stationary random fields converging to stationary random fields. We focus on the study of the bias and the asymptotic normality of the estimators. A simulation experiment conducted shows that both the kernel density estimator and the binned kernel density estimator have the same behavior and both estimate accurately the true density when the number of fields increases. We apply our results to the 2002 incidence rates of tuberculosis in the departments of France.     

Penalized Pseudolikelihood Inference in Spatial Interaction Models with Covariates

Given spatially located observed random variables ( x , z = {( x _i , z _i )} _i , we propose a new method for non-parametric estimation of the potential functions of a Markov random field p ( x | z ), based on a roughness penalty approach. The new estimator maximizes the penalized log-pseudolikelihood function and is a natural cubic spline. The calculations involved do not rely on Monte Carlo simulation. We suggest the use of B-splines to stabilize the numerical procedure. An application in Bayesian image reconstruction is described.     

The embeddedness of organizational performance: Multiple Membership Multiple Classification Models for the analysis of multilevel networks

We present a Multiple Membership Multiple Classification (MMMC) model for analysing variation in the performance of organizational sub-units embedded in a multilevel network. The model postulates that the performance of organizational sub-units varies across network levels defined in terms of: (i) direct relations between organizational sub-units; (ii) relations between organizations containing the sub-units, and (iii) cross-level relations between sub-units and organizations. We demonstrate the empirical merits of the model in an analysis of inter-hospital patient mobility within a regional community of health care organizations. In the empirical case study we develop, organizational sub-units are departments of emergency medicine (EDs) located within hospitals (organizations). Networks within and across levels are delineated in terms of patient transfer relations between EDs (lower-level, emergency transfers), hospitals (higher-level, elective transfers), and between EDs and hospitals (cross-level, non-emergency transfers). Our main analytical objective is to examine the association of these interdependent and partially nested levels of action with variation in waiting time among EDs – one of the most commonly adopted and accepted measures of ED performance. We find evidence that variation in ED waiting time is associated with various components of the multilevel network in which the EDs are embedded. Before allowing for various characteristics of EDs and the hospitals in which they are located, we find, for the null models, that most of the network variation is at the hospital level. After adding these characteristics to the model, we find that hospital capacity and ED uncertainty are significantly associated with ED waiting time. We also find that the overall variation in ED waiting time is reduced to less than a half of its estimated value from the null models, and that a greater share of the residual network variation for these models is at the ED level and cross level, rather than the hospital level. This suggests that the covariates explain some of the network variation, and shift the relative share of residual variation away from hospital networks. We discuss further extensions to the model for more general analyses of multilevel network dependencies in variables of interest for the lower level nodes of these social structures.     

Gender,Field, and Habitus: How Gendered Dispositions Reproduce Fields of Cultural Production

Bourdieu argues that fields of action produce a specific habitus in participants, and views this specific habitus as a mechanism through which the field is reproduced. Although Bourdieu acknowledges the habitus as gendered, he does not theorize gender as part of the mutually constitutive relationship between field and habitus. Using evidence from two cultural fields, the Toronto heavy metal and folk music scenes, I show that gender is central to the process through which field and habitus sustain each other. The metal field produces a “metalhead habitus” that privileges gender performances centered on individual dominance and status competition. In contrast, the “folkie habitus” encourages gender performances centered on caring, emotional relations with others, and community‐building. These differently gendered habitus support different working conventions: music production occurs largely through volunteer‐based nonprofit organizations in the folk field, and individual entrepreneurship in the metal field. The gendered habitus also supports different stylistic conventions: guitar virtuosity in the metal field, and participatory music‐making in folk. Applying a gendered lens to the field–habitus relationship clarifies the mechanisms through which cultural fields shape individual action, and the mechanisms through which cultural fields are reproduced and maintained.
