战国文学的太平洋视域(二)

本文认为鲲化为鹏、海外有山、海外有国以至天外有天的故事,之所以受到部分战国文化巨人的倾情关注,既和当时各国君主崇尚巨美的文化风潮有关,也和一批文学家、哲学家、政治理论家对海天之外的未知领域进行浪漫猜想有关,更和大批文化人士乐于接受随着中西交通而涌进的远方信息有关,甚至还可能和濒海民族尤其是流放远海的越国罪人的航海经历有关。     

The influence of peers and parents on youth life satisfaction in Hong Kong

This investigation attempts to measure the relative influence of peer and parental influence on the perceived life satisfaction of two groups of secondary students in Hong Kong. Data on 1906 students from 30 schools were collected through the use of a self-administered questionnaire. Respondents were asked to rate their level of satisfaction on 26 different domains of life on a seven-point scale, ranging from very satisfied to very dissatisfied, as well as their satisfaction with life in general. These 26 items were combined to form six summary indices of life satisfaction: school life, family life, acceptance by others, government, media, and living environment. Two independent variables were used in the analysis of life satisfaction: peer orientation, and parent orientation. Both are composite indices and measure the adolescent's attachment to and identification with his peers or parents. It was found that parent orientation is a better predictor of life satisfaction than peer orientation. Adolescents who are high on parent orientation are more satisfied with every domain of life. They are also more satisfied with life in general. The relationship between peer orientation and life satisfaction is not a clear-cut one. Adolescents with strong peer orientation are more satisfied with school, media, government, and acceptance by others, but are less satisfied with family. There is no significant relationship between peer orientation and environment. The younger adolescents in our sample tend to perceive a higher level of satisfaction than the older adolescents in every domain of life as well as life in general.     

Composition-consistent tournament solutions and social choice functions

This paper introduces a new axiom for choice in preference profiles and tournaments, called composition-consistency. A social choice function is composition-consistent if it is non-sensitive to the cloning of one or several outcomes. The key feature of the composition consistency property is an operation concept called multiple composition product of profiles. The paper provides a brief overview of some social choice functions studied in the literature. Concerning the tournament solutions, it is proved that the Top Cycle, the Slater and the Copeland solutions are not composition-consistent, whereas the Banks, Uncovered Set, TEQ, Minimal Covering Set are composition-consistent. Moreover, we define the composition-consistent hull of a solution as the smallest composition-consistent solution containing . The composition-consistent hulls of the Top cycle and Copeland solutions are specified, and we give some hints about the location of the hull of the Slater set. Concerning social choice functions, it is shown that Kemeny, Borda and Minimax social choice functions are not composition-consistent, whereas the Paretian one is composition-consistent. Moreover, we prove that the latter is the composition-consistent hull of the Borda and Minimax functions.

我国偏远乡村农产品上行差异化战略

基于差异化战略解决偏远乡村农产品上行问题,有利于解决我国当前“人民日益增长的美好生活需要和不平衡不充分的发展”这一主要矛盾。偏远乡村农地细碎且农产品产量小,却因自然禀赋和精耕细作而具有可实施差异化战略的优势。经济学研究表明：经济越发达地区对高价格接受程度越好,且地理区位距离越远的经济发达地区对高价格接受程度越好,因此,偏远乡村适宜选择地理区位距离相对较远的中心城市实施差异化战略。由于传统流通模式存在供应链长且损耗率高、信息节点多且信息不完全、市场体系不完善且交易方式落后等诸多弊端,提出利用电子商务手段提高偏远乡村农产品的流通效率并提升其产品价值,从重构差异化农产品价值链、构建差异化产品品牌、优化差异化农产品供应链等3个方面着手对农产品上行策略进行优化,从而保证偏远乡村农产品上行差异化战略的成功实现。     

唐长安城胡人居所分布研究

唐王朝曾以其强大的经济、开明的政治以及包容的文化吸引了大规模的四夷入朝,开创了“九天阊阖开宫殿,万国衣冠拜冕旒”的盛景,其中以踏着丝绸之路前来的胡人为甚,胡人在唐长安城的活动极大地影响了唐王朝社会文化风尚.以现存文献、新出土墓志和唐诗为研究资料,探析唐长安城胡人居所的分布规律和迁移轨迹,探明唐前期形成了以西市为核心、以胡商为主体的街西胡人聚居区和以东市为核心、以入仕唐廷的官员为主体的街东胡人聚居区,其中街西胡人圈在唐长安城胡人圈中发挥着主导力量;“安史之乱”后,胡人大规模自西向东迁移,唐中后期街东胡人圈更具群体话语权;此外,以祆祠为中心的胡人居所辐射分布规律长期稳定,投射出胡文化巨大的凝聚力和向心力.     

公共艺术对构建和谐社会的理论审思

从多元文化视角及文化与社会的互动关系论述公共艺术对于构建社会主义和谐社会的作用,具有独特意义。公共艺术作为社会公众艺术,对于建设和谐的社会文化生态,塑造和谐的社会生存空间,促进人与人、人与自然、人与社会的整体和谐都具有十分重要的作用。当前,公共艺术与社会发展之间存在着诸多不协调的现象,需要从体制、意识、内涵等方面寻求突破。     

Workgroup interdependence and satisfaction from a developmental perspective: the moderating role of the group’s life cycle stage / Interdependencia y satisfacción en el grupo de trabajo desde la perspectiva del desarrollo: el rol moderador de la fase del ciclo de vida grupal

From a developmental perspective, workgroups adjust and modify the way they function over time. The present study aims to test, at the group level, the moderating role of the group’s life phase in the relationship between workgroup interdependence ties in terms of task, outcome and functions, assessed by social network density and group satisfaction. A sample of 84 teams from various companies participated in this research. The results showed that the group’s development phase determines the way that outcome interdependence density in teams is associated with satisfaction and reveal the existence of differences between the second and fourth development stages. Therefore, the group’s life cycle stage should be considered as a relevant variable in research and intervention with groups in the workplace.     

MIMCA: multiple imputation for categorical variables with multiple correspondence analysis

We propose a multiple imputation method to deal with incomplete categorical data. This method imputes the missing entries using the principal component method dedicated to categorical data: multiple correspondence analysis (MCA). The uncertainty concerning the parameters of the imputation model is reflected using a non-parametric bootstrap. Multiple imputation using MCA (MIMCA) requires estimating a small number of parameters due to the dimensionality reduction property of MCA. It allows the user to impute a large range of data sets. In particular, a high number of categories per variable, a high number of variables or a small number of individuals are not an issue for MIMCA. Through a simulation study based on real data sets, the method is assessed and compared to the reference methods (multiple imputation using the loglinear model, multiple imputation by logistic regressions) as well to the latest works on the topic (multiple imputation by random forests or by the Dirichlet process mixture of products of multinomial distributions model). The proposed method provides a good point estimate of the parameters of the analysis model considered, such as the coefficients of a main effects logistic regression model, and a reliable estimate of the variability of the estimators. In addition, MIMCA has the great advantage that it is substantially less time consuming on data sets of high dimensions than the other multiple imputation methods.
