Construct validity and generalizability of the Kirton Adaption–Innovation Inventory

The factor structure of the Kirton (1976) Adaption–Innovation inventory was examined by use of confirmatory factor analysis. A three-factor structure was found, characterized by distinct, yet positively associated, facets, thereby challenging the oft-assumed unidimensional conceptualization of adaption–innovation. The measures were found to achieve satisfactory levels of reliability for the separate facets and to exhibit strong evidence for convergent and discriminant validity. This was demonstrated for the full 32-item inventory, as well as 20-item and 13-item abridgments. Subjects were postgraduate students from the United Kingdom (N = 149), Australia (N = 142), and the United States (N = 131). The three-factor solution was found to generalize across all three samples in the sense of yielding identical factor loadings, error variances, and correlations among facets. Differences in the means of factors were found across samples.     

Consumer brand choice: individual and group analyses of demand elasticity

Following the behavior-analytic tradition of analyzing individual behavior, the present research investigated demand elasticity of individual consumers purchasing supermarket products, and compared individual and group analyses of elasticity. Panel data from 80 UK consumers purchasing 9 product categories (i.e., baked beans, biscuits, breakfast cereals, butter, cheese, fruit juice, instant coffee, margarine and tea) during a 16-week period were used. Elasticity coefficients were calculated for individual consumers with data from all or only 1 product category (intra-consumer elasticities), and for each product category using all data points from all consumers (overall product elasticity) or 1 average data point per consumer (interconsumer elasticity). In addition to this, split-sample elasticity coefficients were obtained for each individual with data from all product categories purchased during weeks 1 to 8 and 9 to 16. The results suggest that: 1) demand elasticity coefficients calculated for individual consumers purchasing supermarket food products are compatible with predictions from economic theory and behavioral economics; 2) overall product elasticities, typically employed in marketing and econometric research, include effects of interconsumer and intraconsumer elasticities; 3) when comparing demand elasticities of different product categories, group and individual analyses yield similar trends; and 4) individual differences in demand elasticity are relatively consistent across time, but do not seem to be consistent across products. These results demonstrate the theoretical, methodological, and managerial relevance of investigating the behavior of individual consumers.     

Exploring Attitudes and Predicting Intentions: Profiling Student Debtors Using an Extended Theory of Planned Behavior

This study was designed to investigate application of a theory of planned behavior, including involvement and decision‐making style in predicting undergraduates' borrowing attitudes. We conducted interviews to explore antecedents of students' debt‐consumption/borrowing attitudes. We employed exploratory factor analysis to identify attitudinal dimensions utilized in hierarchical regression as independent variables. The results suggest students regard themselves as good money managers, but lack control over borrowing and debt. Combining involvement and decision‐making style as a style/involvement variable had a powerful mediating effect in predicting borrowing intention. Research suggests that grouping students, based on their involvement level with finance and decision‐making style, into debtor types offers opportunities for more understanding of their debt‐consumption intentions. Strategies are proposed for dealing with different debtor types.     

被遗忘的《古兰经》文化

文化是否能够改变文明，就像人类一样，个人或家族经历中曾被抑制的因素会留下印记，甚至会在当今引发混乱？对上述两种情况，我们是否可以提出假设：以往未解决的冲突和“被遗忘的”，即被抑制的渊源会在当下以不满、冲突和激情的方式重现显现出来？
