西部地区工业竞争力综合评价

本文基于面板数据的因子分析,从经济效益、科技与人才、能源与环保三个维度对西部十一省工业综合竞争力进行评估。结果表明,西部地区工业竞争力总体水平不高且不平衡明显。其中四川、重庆、陕西、广西、云南是西部具有较强的工业竞争力的地区,而贵州、甘肃、内蒙古、新疆、青海、宁夏竞争力较弱。因此要有针对性地实施发展规划,以促进西部地区工业差距缩小与总体发展水平的提升。     

The Aging Semantic Differential in Mandarin Chinese: Measuring Attitudes toward Older Adults in China

ABSTRACT

The Aging Semantic Differential (ASD) is the most widely used instrument to measure young people’s attitudes towards older adults. This study translated the ASD to Mandarin and examined its psychometric properties. The Mandarin-ASD contains three latent factors (Personality and Mental Health, Societal Participation, and Physical) that have high internal reliability and reasonable discriminate validity. Social work researchers, practitioners and allied professionals may utilize the ASD-Mandarin instrument to measure young people’s attitudes towards older adults in China. We issue a call for a universal-ASD that can be applied across different cultural contexts.     

On the mathematics of the Jeffreys–Lindley paradox

This paper is concerned with the well known Jeffreys–Lindley paradox. In a Bayesian set up, the so-called paradox arises when a point null hypothesis is tested and an objective prior is sought for the alternative hypothesis. In particular, the posterior for the null hypothesis tends to one when the uncertainty, i.e., the variance, for the parameter value goes to infinity. We argue that the appropriate way to deal with the paradox is to use simple mathematics, and that any philosophical argument is to be regarded as irrelevant.     

A bibliographic study of public relations in Spanish media and communication journals, 2000–2012

This study analyses the trends and visibility of research on public relations in the most relevant Spanish media and communication journals between the years 2000 and 2012. Bibliometrics and content analysis are used to show the reduced presence of articles on public relations in these publications. A trend towards gender parity in authorship is confirmed in the sample, as well as a plurality of universities and a variety of research themes. The study also proves preference for generic questions rather than for specialised topics. Another finding is that almost one fourth of the specific articles on this discipline do not contain the term “public relations”. This can hint towards the need to have a specific high-impact publication on public relations to bring together and provide visibility to the contributions of researchers in this field.     

Bayesian testing of restrictions on vector autoregressive models

In this study, we propose a prior on restricted Vector Autoregressive (VAR) models. The prior setting permits efficient Markov Chain Monte Carlo (MCMC) sampling from the posterior of the VAR parameters and estimation of the Bayes factor. Numerical simulations show that when the sample size is small, the Bayes factor is more effective in selecting the correct model than the commonly used Schwarz criterion. We conduct Bayesian hypothesis testing of VAR models on the macroeconomic, state-, and sector-specific effects of employment growth.     

What is the Point of Change? Change Point Detection in Relational Event Models

This paper presents an extension to the relational event model with change points (REM-CP) to study abrupt changes to social interaction behavior in temporal networks. A change point detection algorithm is proposed for exploring when and which network effects abruptly change, and a confirmatory approach to test the presence of a change point at a given moment. The effectiveness of the methodology was assessed with numerical simulations and NASA’s Apollo 13 mission data. The latter revealed dynamic communication behavior and identified time zones where most change points occurred, including around the time of the famous quote “Houston, we’ve had a problem.”     

中国旅游上市公司全要素生产率研究

旅游上市公司是旅游业发展的微观主体,其全要素生产率全面反映了该行业的实际经营效率和发展趋势。本文基于Malmquist指数探讨了20家中国旅游上市公司2004-2009年的全要素生产率。Malmquist指数及其分解结果显示:中国旅游上市公司Malmquist指数年均增长率为-0.4%,其中纯技术效率的增长显著,年均增幅为1.3%;时间跨度层面,中国旅游上市公司的全要素生产率的年度波动性较大。此外,样本中旅游上市公司Malmquist指数与营业收入增长率未能兼顾;2008-2009年度粗放型增长的特征显著。     

基于DS／AHP方法的云南省中小企业家能力关键要素辨识

为有效辨识企业家能力关键要素以全面提升云南省中小企业长短期绩效,首先通过合并同类项的文献整合法对国内外相关研究中所涉企业家能力要素进行归纳与提炼,然后应用DS／AHP方法融合学术界、政府界、从业界三方对不同准则下中小企业家能力要素或要素集的偏好判断信息,最后基于累积标准化似然值大于0．8的要素甄选原则辨识出影响云南省中小企业绩效的企业家能力关键要素。实证结果表明,战略能力、概念能力、机会能力、关系能力、组织领导能力以及学习能力是目前影响云南省中小企业绩效的企业家能力关键要素。     

中国工业部门全要素能源效率状况分析——基于2005—2009年省际面板数据的实证研究

基于2005—2009年省际规模以上工业面板数据,构建DEA模型,从静态和动态两个角度实证分析了中国工业部门全要素能源效率状况。从静态角度来看：（1）中国工业部门全要素能源效率整体上处于中优水平,有约25％～40％的节能空间;（2）工业生产过程表现为能源利用相对低效,全要素能源效率低于全要素技术效率;（3）区域之间和区域内部的差畀性较大。工业全要素能源效率值在区域之间自东向西递减,而地区内部的差异性却自东向西增大。从动态角度来看：（1）2005—2009年,工业部门全要素能源效率整体上未发生实质性变化,绝大部分省份也未发生实质性变化;（2）工业全要素能源效率全国范围内差异性有减小趋势,各地区内部差异性将持续存在。     

基于投入产出表的安徽省主导产业集群的识别与评价

基于2002年和2007年安徽省投入产出的有关资料,对安徽省的6个主导产业集群做了具体的识别、界定和评价。本文的政策建议是：壮大农业—食品业集群、轻工—纺织业集群以及煤炭—电力业集群;升级教育—公共管理集群、文化产业集群以及化工—医药集群;培育电子产业集群。从而促进安徽省经济更快更健康地发展。
