The effect of scale size on obtaining information in preference testing

The effect of scale size upon response is the subject of this study. The same questions (regarding preferences) were put to four equal-sized groups measuring preference with four different scale lengths; a three-point scale, a five-point scale, a seven-point scale, and a nine-point scale. This paper describes the results obtained.

Psychometrically and qualitatively validating a cross-national cumulative measure of fear-based xenophobia

The article reports the results of a Mokken Scale Procedure (MSP) developing a hierarchical cross-national scale to measure xenophobia, and a qualitative validation of this scale. A pool of 30 xenophobic scale items were collected from several sources and edited according to established unidimensional criteria. The survey was administered to 608 undergraduate students in the USA, 193 undergraduate students in the Netherlands, and 303 undergraduate students in Norway. Fourteen scale statements measuring perceived threat or fear and meeting the criteria of the Stereotype Content Model (e.g., Fiske et al. in Trends Cogn Sci 11:77–83, 2006) were selected for further analysis. A separate item analysis and subsequently MSP analysis yielded a cumulative scale with the same five items for each of the three samples meeting criteria for homogeneity in all samples with H >.40. The result, a cross-national 5-item scale measuring fear-based xenophobia, was tested by means of the Three-Step Test-Interview (Hak et al. in Surv Res Methods 2:143–150, 2008) with 10 students in The Netherlands and 10 students in Norway. The analysis of these qualitative interviews shows that individual respondents’ criteria for the ranking of the scale items strongly depend on the way immigrants are framed. Ranking according to different levels of fear turned out to be only one criterion out of several possible ones used by individual respondents.     

HR accounting as a measurement tool

In tracing the history of human resource accounting, most reviewers would agree that the topic is now experiencing something of a revival. This research set out to explore why HR accounting is regarded as important, to whom it is important and its links with organisational and HR strategies. We used a survey‐questionnaire approach to gather data. A scale was developed measuring the extent to which respondents thought each item reflected their organisation's view on the importance of measuring of human resources. Component analysis revealed two reasons why measuring human resources is perceived as being important. The first illustrates the view that ‘measurement reflects the strategic and competitive importance of human resources’, while the second suggests that,‘to earn credibility, HRM must be expressed in financial terms’. Further analysis highlighted the importance of senior management and financial managers' support for measuring human resources and drew attention to what may appear to be a ‘hard view' of HRM held by HR managers in relation to why they consider this important.     

Scale Efficiency and Productivity Change

Thefirst objective of this paper is to develop a generic measureof scale efficiency for a multiple-input multiple-output firm,using basic principles of modern production theory. The secondobjective is to combine measures of technological change, technicalefficiency change, and scale efficiency change into an encompassing(primal) measure of productivity change. This measure and itsdecomposition is compared to a number of recent proposals inorder to shed light on what seems to have become a controversialissue. The paper proceeds by developing an encompassing dualmeasure of productivity change. This dual measure is then appliedto panel data of a set of Dutch firms, continuing the empiricalwork of Balk (1998). It turns out that extending the Malmquistproductivity index with factors measuring scale efficiency changeand input mix change leads to appreciably different outcomes.     

品牌延伸评价研究:个性匹配视角

本文从消费者个性角度探讨消费者与品牌延伸之间的相互关系。研究以消费者性别人格个性为出发点,依照个性源于消费者人格并赋予品牌的逻辑,尝试运用Aaker(1997)的五维个性量表测量消费者、品牌和延伸产品个性,并聚类三者个性展开品牌延伸实验。实验数据统计及ANOVA分析结果表明,个性匹配能带来较高品牌延伸评价和对品牌正面反馈效应,不匹配品牌延伸品牌稀释效应不显著。同时,验证Aaker(1997)个性量表测量中国消费者、品牌及延伸产品的可行性。

Product diversification,production systems,and economic performance in U.S. agricultural production

The U.S. agricultural sector is experiencing significant structural change. Farm size is rising and activities are broadening, including more off-farm employment, implying economic incentives for larger and more diversified farms, and complementarities among agricultural netputs. We quantify such patterns for farms in the corn belt, by measuring scale economies, and output and input contributions and jointness. We estimate the multi-output and -input production technology by stochastic frontier techniques applied to output and input distance functions. We find that both scope and scale economies have important economic performance implications, and that an input-oriented framework including off-farm income best characterizes agricultural production.     

Measures in DEA with an Application to the Malmquist Index

This paper shows the importance of goal vectors G in measuring and dealing with DEA inefficiencies. It emphasizes the advantages of the family of additive relative to the traditional oriented DEA models and shifts the primary emphasis to measuring inefficiency rather than efficiency. This new (raw) inefficiency measure RIN incorporates both the traditional DEA efficiency and the DEA slacks and provides the background for a new approach to the Malmquist Index. The final section points out some deficiencies in existing computational procedures for selecting G and calls for continued research on the selection process, as well as showing a role for G in returns to scale studies.     

Critical success criteria for B2B E-commerce systems in Chinese medical supply chain

The paper presents an exploratory investigation to determine and prioritise the critical success criteria, which can measure and guide the successful application and performance improvement of business to business e-commerce system (BBECS) in a medical supply chain's selling and buying functions, in the context of global business expansion. The research reveals that the buying and the selling functions have different prioritisations on the majority of the determined critical success measuring criteria. These criteria are categorised into three Critical Success Measuring Criteria Groups, for the selling and the buying functions, respectively, guiding medical supply chain members in harnessing the full advantage of a BBECS. For the selling function, the top critical success measuring criteria are as follows: integrating information searching/transmission and application processes, ensuring the reliability and timeliness of technical support, ensuring recognition and acceptance of e-commerce processes, displaying the organisation's business focus and product/service provisions online, securing a large scale/amount of business transactions, adjusting production outputs and inventory levels and having more registered users than competitors do. The top critical success measuring criteria for the buying function are as follows: securing the establishment of business relationships between businesses, displaying the measures ensuring mutual trust and cooperation online, ensuring employees' recognition of the benefit of e-commerce in increasing revenue, ensuring the contribution to the development and realisation of corporate strategy, achieving cost reduction for the organisation, making the purchase of famous brand products available/doable, securing a large scale/amount of business transactions, and ensuring the attainability of products/services at a lower price.
