基于路径分析的科技成果评价指标赋权方法研究

指标赋权是科技成果评价过程中的关键环节。通过建立路径模型，对科技成果评价指标进行路径分析，在消除其他因素影响的基础上，确定原因变量（指标）对结果变量（指标）的直接影响，并据此对指标进行赋权。实证分析表明，该赋权方法具有可操作性和实用性。

Factors that influence reading and comprehension of branching instructions in self–administered questionnaires

Summary: In this paper we examine the tendency for branching instructions to be ignored, misread, or otherwise not appropriately followed so that item nonresponse occurs for follow–up questions. The potential influence on branching errors of seven features of question complexity are examined, including high number of question words, high number of answer categories, last categories branch, all categories branch, write–in responses, location at the bottom of a page, and high distance between the answer box and branching instruction. A logistic regression analysis revealed that question complexity had a tendency to increase certain errors, but not others.* A more detailed version of this paper with additional analysis and discussion is available at http://www.sesrc.wsu.edu/dillman/. The opinions expressed here are those of the authors, not necessarily of the institutions where they presently work or the U.S. Census Bureau, which provided financial support for the collection of these data. We would like to thank Aref Dajani and Yves Thibaudeau for their advice on the analysis used in this paper.     

单李代数不可约表示的标记

对于n秩单李代数g,当采用Dynkin关于素根的分类时,其不可约表示可以用n个非负整数Λ_(αi)标记,也可通过初等表示的权用数组li来标记。利用Cartan逆矩阵,我们给出了计算Λ_(α_i)与li之间关系的方法。对于B_n、C_n、D_n和F_4,利用Cartan逆矩阵证明了这些li是与采用Cartan关于素根的分类时的Λi是一致的。     

Quality of life indicators and program evaluation

Social indicators and program evaluation research have much in common. Quality of life work specifically raises the question of objective versus subjective variables, aggregate data versus distributional and individual issues, and the reference standards used in judgment and evaluation decisions. This article presents perspectives on these issues from the orientation of quality of life research and proposes that these approaches have relevance for program evaluation work.

制造业集聚对新型城镇化的影响研究——基于空间溢出效应的视角

文章依据2014—2020年《国家新型城镇化规划》,构建了中国新型城镇化水平综合评价体系,并基于熵权法测算了2003—2015年中国大陆31个省份新型城镇化水平。在此基础上,通过构建空间杜宾模型,考察了中国制造业集聚的空间交互效应,并在控制了对外出口、金融发展以及财政支出的情况下研究了制造业集聚对新型城镇化的影响。研究结果表明：中国制造业集聚具有显著的空间依赖特征,表现出明显的"集聚俱乐部"现象。制造业集聚显著地推动了中国新型城镇化建设,同时其空间溢出效应明显,在推动本地区新型城镇化的同时还能有力地带动周边地区新型城镇化的发展。地方财政支出的增加有助于显著推动新型城镇化建设,并且地区之间财政行为存在空间互动,邻近地区通过扩大财政支出也能刺激本地区的新型城镇化建设。同时,对外出口和金融发展也是新型城镇化建设中不可或缺的力量,但其空间溢出效应却不明显,并未对周边地区产生明显的影响。对此,建议应该以产业集聚区作为城市功能外溢的核心地区,不断完善集聚区相关配套的基础设施和公共服务体系,实现产城融合的良性发展态势。     

Measuring Kurtosis by Right and Left Inequality Orders

The question of how to measure kurtosis in both symmetric and asymmetric distributions is addressed using the kurtosis diagram of Zenga (2006 Zenga , M. ( 2006 ). Kurtosis . In : Kotz , S. , Read , C. B. , Balakrishnan , N. , Vidakovic , B. , eds. Encyclopedia of Statistical Sciences. 2nd ed . New York : John Wiley and Sons . [Google Scholar]). Kurtosis is related to inequality at either side of the median, and we establish a hierarchy of kurtosis orderings in which the kurtosis diagram stands at the weakest level. A sufficient condition for constructing kurtosis measures compatible with such ordering is provided. The merits of the proposed approach in both clarifying and formalizing the idea of kurtosis are evaluated and examples are discussed throughout.     

On the Use of a Log-Rate Model for Survey-Weighted Categorical Data

For the analysis of survey-weighted categorical data, one recommended method of analysis is a log-rate model. For each cell in a contingency table, the survey weights are averaged across subjects and incorporated into an offset for a loglinear model. Supposedly, one can then proceed with the analysis of unweighted observed cell counts. We provide theoretical and simulation-based evidence to show that the log-rate analysis is not an effective statistical analysis method and should not be used in general. The root of the problem is in its failure to properly account for variability in the individual weights within cells of a contingency table. This results in goodness-of-fit tests that have higher-than-nominal error rates and confidence intervals for odds ratios that have lower-than-nominal coverage.     

An improved estimator of omission rate for census count: With particular reference to India

ABSTRACT

Every large census operation should undergo evaluation programs to find the sources and extent of inherent coverage errors. In this article, we briefly discuss the statistical methodology to estimate the omission rate in Indian census using dual-system estimation (DSE) technique. We have explicitly studied the correlation bias factor involved in the estimate, its extent, and consequences. A new potential source of bias in the estimate is identified and discussed. During the survey, more efficient enumerators compared to the census operations are appointed, and this fact may inflate the dependency between two lists and lead to a significant bias. Some examples are given to demonstrate this argument in various plausible situations. We have suggested one simple and flexible approach which can control this bias. Our proposed estimator can efficiently overcome the potential bias by achieving the desired degree of accuracy (almost unbiased) with relatively higher efficiency. Overall improvements in the results are explored through simulation study on different populations.
