不公平有几何？——中国城市居民收入分配公平感的测量

文章首先通过批判性地介绍几种已有的公平感测量方法,选取其中最为合适的一种在CGSS2005数据基础上测量中国城市居民的反身性公平感和非反身性公平感。其次,分别以性别、年龄、教育和单位体制变量分组,从多方面呈现了两种公平感在中国的现状。最后,作者通过使用对总体样本进行随机性拆分得到的两个样本对此测量方法的信度进行了验证。     

基于隐马尔可夫链模型的电子商务用户兴趣导航模式发现

用户智能导航模式发现已经成为电子商务领域中的一个研究热点。为此,结合电子商务站点用户网页访问时间与网页关键字信息对用户访问兴趣进行定义,借鉴经典隐马尔可夫链模型,建立用户兴趣导航模型。给出在此模型中用户兴趣导航路径的发现方法及算法描述。通过模拟数据、某B2C在线图书销售站点中的真实数据以及与经典方法的对比等方面的实验验证,结果表明：给出的模型方法能够准确、高效地找到带有用户访问兴趣的关联路径信息。这个方法可以作为一种应用于电子商务领域更为有效、实用的智能导航发现工具。

农民专业合作社理事长能力测度与培育——基于运城市100家合作社的实证研究

基于运城市100家合作社的调查数据,确定测度合作社理事长能力的9个维度:政府关系能力、社会关系能力、管理能力、战略能力、创新能力、资源整合能力、学习能力、操作能力和机会能力,并对理事长能力的差异性之根源以及理事长能力的培育进行探讨。实证结果表明:在理事长能力的结构中,政府关系能力贡献最多,其次是创新能力,再次是资源整合能力,其他依次为社会关系能力、管理能力、战略能力、学习能力、操作能力和机会能力。理事长能力主要受合作社组建方式、合作社产品类型、理事长受教育程度和担任理事长的时间影响。合作社理事长能力的培育可以通过政府扶持政策、理事长自身素质的提高以及完善理事长助理制度等三方面来实现。

Semiparametric inference for estimating equations with nonignorably missing covariates

We consider statistical inference of unknown parameters in estimating equations (EEs) when some covariates have nonignorably missing values, which is quite common in practice but has rarely been discussed in the literature. When an instrument, a fully observed covariate vector that helps identifying parameters under nonignorable missingness, is available, the conditional distribution of the missing covariates given other covariates can be estimated by the pseudolikelihood method of Zhao and Shao [(2015), ‘Semiparametric pseudo likelihoods in generalised linear models with nonignorable missing data’, Journal of the American Statistical Association, 110, 1577–1590)] and be used to construct unbiased EEs. These modified EEs then constitute a basis for valid inference by empirical likelihood. Our method is applicable to a wide range of EEs used in practice. It is semiparametric since no parametric model for the propensity of missing covariate data is assumed. Asymptotic properties of the proposed estimator and the empirical likelihood ratio test statistic are derived. Some simulation results and a real data analysis are presented for illustration.     

Techniques and paradoxes in performing performance measurements: concluding reflections

ABSTRACT

Performance measurement has an implicit performance theory embedded within its practice; performance measurement perforce performs. Performance measurement has a performative effect on performance. Drawing together and building on the various empirical observations from the preceding papers in this collection, this concluding paper firstly examines the circumstances in which performance measurement performs, that is, when it produces ‘authentic’ performance improvements, compared to when performance measurements misfire. The paper secondly explores several paradoxes of performance measurement – such that performance measurement measures only part of the performance it seeks to be performative on, incentives to perform incentivise poor performance and so on. These paradoxes, contradictions and ironies must be apprehended and appreciated in discovering, discerning and deciphering the diverse dynamics of measuring performance. They also demonstrate that analysing and working with performance measurement requires a perspective that eschews absolutes and clear directions, and embraces the uneasy and potentially destabilising tension of Escher’s performative art.     

Hitting the target without missing the point: New Zealand’s immunisation health target for two year olds

ABSTRACT

The use of health targets as a form of performance measurement has become more prominent internationally as governments have sought to control public expenditure, produce greater efficiency and improve accountability. However, health targets have faced criticism for their potential to produce negative outcomes within a health system. This paper examines how a health target was used as a policy instrument within the New Zealand health system to improve immunisation coverage at two years of age. It explores how the immunisation health target was implemented within four case study sites and discusses the effectiveness of the health target as a policy instrument for improving immunisation coverage and addressing persistent immunisation inequities. Measuring and monitoring performance towards the immunisation health target improved accountability for immunisation coverage within the New Zealand health system and focused attention on improving immunisation coverage in a way that previous policy attempts had failed to do. Health targets may be an effective policy instrument for creating change within specific areas of a health system if their potential for dysfunctional consequences are taken into consideration at the outset.
