基于指标体系的我国环保产业区域发展比较研究

本文以2010~2012年中国统计年鉴中的环保指标和数据为基础,并归纳总结我国环保产业相关文献的指标数据,从环保产业区域发展不平衡的角度,研究了我国各区域环保产业的现状和问题,分析评价各个区域生态环境的特点,并结合国外产业发展历史经验,提出我国区域差异的环保产业发展对策,对我国生态文明建设具有重要意义。     

基于缺陷扣分法与模糊理论相结合的GIS数据质量评价——以基本农田成果数据为例

本文通过对GIS数据评价的因素进行分析,改善专家综合评语所得到的模糊关系矩阵。以基本农田调查数据库为基础,运用缺陷扣分的方法,对各因素集进行打分评判,计算出各因子在产品质量等级中所占有比重,结合专家综合评语,得到较准确的模糊关系矩阵。通过层次分析法计算出各因素的权重分配,根据模糊矩阵合成规则合成模型,依照最大隶属原则,得出最终的评价结论。     

进出口商品质量指数在进口棉花上的应用

为了评价进出口商品的综合质量水平,研究构建了进出口商品质量指数测评模型。统计历年来棉花检验检疫、通报退运、不合格货值等数据,通过对各相关指标的权重设置,选定一个基期,测算出进口棉花质量指数。再通过一个时期不间断的数据采集及分析,可以得知该时间周期内进口棉花质量水平的变化情况,并对不合格情况提出警示。研究结果可以提高检验检疫监管效能,有利于各级监管部门进行有效监管。     

和谐社会评价指标体系与评价模型及其应用

根据和谐社会的内涵与特征,选取4个方面18个评价指标组成层次结构指标体系,引入模糊隶属函数对各指标进行无量纲化处理,利用因子分析法确定各级指标权重,构建模糊综合评价模型对我国社会和谐度进行综合评价,并对评价结果进行分析。结果显示,我国社会总和谐度处于一般和较高之间,离全面建设社会主义和谐社会的目标仍有一定的距离。     

The influence of activity importance and similarity on perception of recreation substitutes

Abstract

This study examines how substitutes are selected for a fly‐angling and camping recreation activity. Results show that although people choose substitutes similar to their intended activity, the degree of similarity between substitute and original is unrelated to perceived quality of substitute. Also, both the quality of a substitute and the number of available substitutes are inversely related to the importance of an activity's attributes. The lack of a relationship between activity/substitute similarity and quality of the substitute poses problems for application of the substitutability concept.     

MATLAB在专用线危险品装卸区安全评价中的应用

目前铁路专用线运输和装卸危险化学品的安全评价,普遍使用的道化学法和TNT当量模型计算法存在计算过程烦琐、结果不直观、不方便比较和查阅、不能迅速判断事故的伤害区域等缺点。研究将MATLAB应用于专用线易燃易爆危险品装卸区安全评价,对蒸气云爆炸后果进行模拟,得出死亡半径,并将计算绘制成各种图形结果。利用MATLAB对专用线危险品装卸区进行安全评价,发挥其计算和分析优势,可以缩短评价周期,提高评价效率。     

The employment interview: A review of current studies and directions for future research

The employment interview continues to be a prevalent device used by organizations and a popular topic of study among researchers. In fact, over 100 new articles have been published since Posthuma, Morgeson and Campion's [Posthuma, R. A., Morgeson, F. P., & Campion, M. A. (2002). Beyond employment interview validity: A comprehensive narrative review of recent research and trends over time. Personnel Psychology, 55, 1–81] review that are selectively examined and critiqued. During this timeframe, three main areas that have received considerable research attention are discussed: (1) understanding why “structured” interviews predict, (2) examining the constructs interviews may measure, and (3) investigating the applicant and interview factors that may affect the interview process. Despite advances made in our knowledge of employment interviews, numerous ideas for future research are advanced. Three key areas that deserve immediate research attention are: (1) establishing a common model and measurement of interview structure, (2) focusing on what constructs could be or are best measured, and (3) formulating consistent definitions, labeling and measurement of applicant factors. In this way, employment interview research can be advanced.     

Gerrymandering in personnel selection: A review of practice

Gerrymandering personnel selection systems is defined as those practices explicitly intended to improve the outcomes of individual applicants or groups of applicants to the detriment of other individuals and groups. Gerrymandering can serve a variety of purposes, such as enhancing demographic diversity, rewarding political allies, or giving hiring preference to specific individuals. This paper reviews eleven strategies for gerrymandering personnel selection systems. The strategies fall into three categories of decisions: decisions in choosing or designing personnel selection tools; decisions in scoring personnel selection tools; decisions in selecting among passing applicants. Perspectives on the appropriateness and ethics of gerrymandering are then reviewed.     

Market Positioning of Differentiated Products

A brand is a mean of product differentiation and a kind of a sign by which we can distinguish one commodity from another. Consumers' utility, as well as commodity prices are affected by brands. Therefore, the market positioning of branded products is important for firms, too, since it affects profits. This paper presents a theoretical framework that incorporates aspects of brand in microeconomic analysis and the tools for an effective market positioning of differentiated products. A case study illustrates the workings of the methodology; the application evaluates the quality of major tyres producers and undertakes their market positioning.
