Due to the rapid expansion of perceived e-shopping risks, and highly isolated and inconsistent presentation of literature about this concept, understanding e-shopper's behavior has become more difficult. In this regard, this study brings together different views, evidences and facts about perceived e-shopping risks from both scholars and practitioners of South-East Asian and Western countries. It then interprets the information in the form of a new scale which offers more adequacy, assemblage and uniformity than the existing models of perceived risks of e-shoppers. The new scale of construct has 11 dimensions comprising a pool of 38 items, which has been empirically validated through the data collected from 537 Malaysian e-shoppers. The dimensions are: high price risk, deception risk, transaction failure risk, dissimilar product risk, incapable service risk, illegitimate product risk, isolation risk, unease risk, displeasure risk, prior-purchase time delays risk, and post-purchase time delays risk. The theoretical and managerial implications and research limitations have also been discussed.  相似文献

创客组织是实现组织协同创新的重要载体。创客位于组织协同系统的核心层,创客入驻创客组织的创新状态决定了协同创新发展状态;创客组织位于组织协同系统的中间层,起组织协调作用,其发展稳定性影响着整个系统;协同组织位于外部层,其参与程度决定了整个系统的组织协同和协同创新吸引能力。基于波动系数计量模型,对240家创客组织的12项评价指标进行分析,结果显示,以高校主导的创客组织衡量指标波动系数为标准,创客组织在整体上处于发展不稳定状态;分类别分析结果表明,高校和科研院所主导的创客组织发展稳定性明显优于企业和个人主导的创客组织。研究结果可以为完善创新政策、促进创客组织稳健发展提供参考。  相似文献

In investigating consumers’ intentions to re-purchase organic personal care products (PCP), this study extends the theory of planned behaviour by including perceived value dimensions as the antecedents of attitude in the model. The findings revealed that most of the hypothesised relationships linking the consumer perceived value constructs (namely, health, safety, hedonic and environmental) with attitude towards the rebuying of organic PCP, were supported. Also, better product knowledge about organic PCP would lead to more positive attitudes towards re-purchasing the product. In contrast, social value was not important in predicting attitude. Similarly, the influence of subjective norm on rebuying intention was not supported. In terms of ranking of importance with regards to prediction of re-purchasing intention, attitude was the most important predictor followed by perceived behavioural control, product knowledge, hedonic value, environmental value and safety value.  相似文献

This research aims to study the origins of consumers' usefulness perceptions through the example of mobile online shopping adoption in Europe. The results of an empirical study, which is grounded in technology acceptance theory, reveal the pivotal role of consumers' beliefs about the quality of mobile online stores in the formation of usefulness perceptions prior to adoption. While this study identifies that consumers form their usefulness evaluations depending on the respective shopping tasks, the results of a moderation analysis yield usefulness predictors that differ in relevance across product categories and shopping touchpoints. This contextual perspective has implications for both adoption and (online) channel research. It also helps managers to identify starting points on how to promote (mobile) online shopping adoption.  相似文献

在分类应用的过程中,经常会出现新的类别,导致数据分布发生显著变化,使得原分类模型不再适用。如何识别新的类别使分类模型能适应其出现已经成为一个亟需解决的问题。本文提出基于特征增量的SVDD(支持向量数据描述)新类识别方法。该方法在SVDD算法的基础上,通过增加新特征,扩大特征空间维度从而提高模型对于新类的识别能力。在多个数据集上的实验结果表明,该方法能有效识别新类,使更新后的模型具有更高的准确度。  相似文献

Despite extant literature, the most effective structure of loyalty programs is still heavily questioned among researchers. Building on the congruence principle, we examine the moderating role of brand concept. Our findings reveal that for symbolic brand concepts, customers perceive hierarchical loyalty program structures (which classify customers into tiers according to spending levels or other purchase activities) to be more congruent; this perception increases firm loyalty intentions. However, for functional brand concepts, customers perceive hierarchical and linear loyalty programs structures as equally congruent. Also for symbolic brand concepts, program structure appears as the most important feature in ensuring perceived congruence between a program and a brand, ahead of program benefits. These findings have important theoretical and managerial implications.  相似文献

This article offers a new and interesting perspective on organizational buying behavior by focusing on the simultaneous existence of both cooperation and competition, that is, coopetition. Coopetition may bring undesired knowledge leaks, opportunism, and weakened competitive advantage, and it is therefore important to understand how coopetition develops over time through interrelated activities on multiple levels. The article aims to improve our understanding of the development of organizational buying behavior through adopting a multilevel perspective on coopetition. The empirical study is based on exploratory case study research involving a single case from the manufacturing sector featuring a large multinational buyer and its supplier. The findings of the study show that organizational buying behavior in coopetition develops through interrelated activities on the individual, the organizational, and the relational level. Over time, dominating activities evolve from being ambivalent on an individual level to become authoritative on a company level and finally to being opportunistic on a relational level. Theoretically, this study contributes to organizational buying behavior literature by examining coopetition from a multilevel perspective. From a managerial perspective, the findings establish the importance of recognizing individual-, and organizational-level activities.  相似文献

Central to the evolution of a digital business platform is the organization’s ability to balance exploration (renewal) and exploitation (refinement) simultaneously. Drawing on prior research—including digital platforms, contradictory tensions, and organizational ambidexterity—and our own experience investigating digital business platforms in organizations, this article provides insights into how executives can manage this evolution successfully. More specifically, we present a framework recognizing three pairs of organizational capabilities (i.e., identifying-nourishing, expanding-legitimating, and augmenting-embedding) that enable balancing renewal and refinement of the platform over time. We close by providing critical managerial practices that executives can use in anticipating, adjusting, and evaluating the evolution of a digital business platform over time, including its initiation, development, and growth.  相似文献
