Development and validation of a situational judgement test of Japanese leadership knowledge

ABSTRACT

Leadership research has accumulated a wealth of empirical findings about what leadership behaviours are effective in various business environments. We took advantage of these empirical findings to develop a situational judgement test (SJT) of leadership knowledge with correct answers. The SJT contains four leadership dimensions: task-focused, relationship-focused, transformational, and developmental leadership. Item response theory and confirmatory factor analyses were used to examine the psychometric properties of the SJT, based on a sample of 658 Japanese college students. Ultimately, we confirmed a four-factor model and retained 21 of 53 situation questions for the final SJT.

Job satisfaction and organizational commitment: validating the Arabic satisfaction and commitment questionnaire (ASCQ), testing the correlations,and investigating the effects of demographic variables in the Lebanese banking sector

The aim of this study was to assess the construct validity and the reliability of two measurement scores of organizational commitment and job satisfaction, to measure the correlation between the two variables, and to explore the effects of different demographic variables on satisfaction and commitment in a Lebanese context. A total of 298 cases from five major banks were analyzed. Rigorous forward and backward translation procedures have been applied to ensure the relevance of this instrumentation in a different cultural context. Results of exploratory factor analysis, confirmatory factor analysis, simple item-internal consistency estimates, and item intercorrelation analysis provided evidence that both instruments have produced reliable measurement scores with construct validity adequate to measure satisfaction and commitment in the Lebanese context. Results also showed that the constructs of satisfaction and commitment were significantly correlated and that satisfaction was a good predictor of commitment. Demographic analysis, discussion of these results, and suggestions for future research were proposed.     

The Role of Reward Systems in Product Innovations: An Examination of New Product Development Projects

Focusing on new product development projects, this study suggests that the effect of a market orientation on innovation performance relationships may differ depending on whether the market orientation is responsive or proactive. This study also argues that process‐based and outcome‐based rewards moderate the effect. Based on a survey of 186 new product development projects in 122 high‐tech firms, this study found that responsive and proactive market orientations have positive influences on incremental innovation performance and radical innovation performance, respectively. In addition, the positive effect of a proactive market orientation on performance is strengthened by process‐based rewards, whereas the positive effect of a responsive market orientation on performance is positively moderated by outcome‐based rewards. This study provides practical implications and directions for future research.

Gift cards: a review and research agenda

Gift cards have received limited study despite being a key element of many retailers’ strategies. One reason may be that approaching the study of gift cards from a traditional economic perspective, i.e. ignoring social relationships, leaves little justification for the rapid increase in gift card sales. Failing to see the value of gift cards, many commentators go so far as to argue against the purchase of gift cards, suggesting that consumers would better off using other gift types. This misses the important point that givers voluntarily buy cards and receivers enjoy gaining them. Consumers undoubtedly perceive the value in gift cards. We suggest that taking a broader perspective on consumer behavior and considering consumers involved in social systems that encourage gift giving, allows us to see the value gift cards create while allowing us to address the concerns gift cards raise more effectively. In this article, we detail the benefits created for givers, receivers, and merchants by the use of gift cards. We highlight areas with significant public policy implications. We outline an agenda for some promising areas of research, including seeking to gain a better understanding of the psychology of giving gift cards and the economics of retail strategies dependent upon gift card usage.     

Ambidextrous Idea Generation—Antecedents and Outcomes*

Ambidexterity, defined as the capability to develop both incremental and radical innovations, is an important driver of firm success. Idea generation is an essential starting point for both types of innovation. Therefore, this study investigates whether ambidextrous idea generation, defined as the capability to actively generate both incremental and radical ideas, affects new product development (NPD) success. Analyses on the Comparative Performance Assessment Study (CPAS) data, which includes data from 453 companies distributed over 24 countries, demonstrate that ambidextrous idea generation does indeed affect NPD program success. Consequently, this study also investigates which antecedents foster ambidextrous idea generation. The innovation paradox concept predicts that achieving ambidexterity requires overcoming paradoxical antecedents. Therefore, we tested whether combinations of financial and breakthrough orientations (the paradox of strategic emphasis), a formal innovation process and an innovation culture (the paradox of innovation drivers), tight and loose customer coupling (the paradox of customer orientation), and internal development and external collaboration (the paradox of openness) affects ambidextrous idea generation. The results show that only customer orientation and openness have the expected inverted u‐shaped effect. These finding are in line with construal level theory, which predicts that the organizational characteristics that influence idea‐generation activity must be at the same construal level to have the desired effect. The contribution of this study is twofold. First, the analyses indicate that ambidextrous idea generation has significant repercussions for the entire NPD program. Second, the results show that resolving innovation paradoxes only has an effect if the construal level of the paradox and the activity match. This finding indicates an important boundary condition for the innovation paradox concept.     

E-lifestyles of Indian online shoppers: A scale validation

Online shopping in India is growing at a dramatic rate and marketers are still working on understanding the lifestyles of online shoppers for purpose of segmentation, targeting and promotions. The scales for such requirements developed in other countries may not be apt for use in India. Hence there is a need to develop appropriate scales applicable in the Indian context. By way of review of the previous literature as well as exploratory study through interviews and focus group with online shoppers and experts in the field, the authors develop a pool of items relating to electronic lifestyles, henceforth called e-lifestyles of Indian online shoppers. Further using exploratory as well as confirmatory factor analysis, reliability and validity of the scale is confirmed and a six factor scale consisting of e-enjoyment, e-distrust, e-self-inefficacy, e-logistic concerns, e-negative beliefs and e-offers is developed. The study is a first step towards identifying a more holistic picture of factors that influence Indian online shopper lifestyles or e-lifestyles. The findings of this study can be integrated into marketing and promotional strategies of the web retailers.
