This research attempts to exemplify whether pets ascribed as possessions can be regarded, as part of our selves, i.e., a metaphoric relationship with pets, by examining the dynamic relationship between beliefs, extended self, self-identity concerning possessions, and psychological ownership.This study extends the literature by developing a conceptual model asserting that probabilities of purchase for pets, in particular, are contingent on possessions and the extended self. A sample of 326 pet owners was selected, and by using SEM, the direct and indirect relationships were explored. Self-identity and beliefs were significantly associated with psychological control and the extended self, however, beliefs were negatively related to the probabilities of purchase. The extended self and the psychological ownership demonstrated mediating relationships. The study contributes to an understanding of the theoretical relationship between the role of possessions and provides scholars and retail practitioners with an understanding of probabilities of purchase for pet fashions.  相似文献

Since Benford’s law is an empirical phenomenon that occurs in a range of data sets, this raises the question as to whether or not the same thing might be true in terms of the Chinese income distribution data. We focus on the first significant digit (FSD) distribution of Chinese micro income data from the 2005 Inter-Census sample, which corresponds to 1% of Chinese population and other micro income data from the China family panel studies (CFPS) and Chinese General Social Survey (CGSS). We use information theoretic-entropy based methods to investigate the degree to which Benford’s FSD law is consistent with the FSD of Chinese income data and our findings suggest consistency between the Chinese FSD income distribution and Benford’s distribution. The close connection between the two distributions has implications for the quality of the sample of Chinese micro data.  相似文献

Although many scholars have demonstrated that companies engaged in collaborations achieve better environmental performance than other companies, existing studies have not analyzed in depth whether this effect changes considering the characteristics of cooperation. Our paper aims to explore whether collaboration with other companies always has a positive effect on environmental performance or whether it depends on cooperation goals, collaboration type, or company size. Empirical analysis based on a sample of 773 European companies demonstrated that an external source of knowledge is an important way to foster firms' environmental proactivity, especially when environmental goals are shared at the basis of collaboration. Second, we verified that companies involved in JVs with environmental goals achieve greater environmental performance than companies that use M&As to acquire external knowledge. Finally, we demonstrated that it is more important for small companies to be involved in environmental collaboration than larger ones.  相似文献

This study aims to broaden the current knowledge on the antecedents and consequences of customers’ psychological ownership (CPO) from new perspectives in the hotel context. Specifically, this study investigates how self-image congruity and functional congruity affect CPO through impression in memory based on self-congruity theory and also examines two types of customer engagement—customers’ social influence engagement and knowledge-sharing engagement—as new CPO outcomes. Using survey data collected from 433 Chinese hotel customers, this study finds that self-image congruity positively predicts CPO partially through impression in memory, whereas functional congruity positively influences CPO fully through impression in memory. Moreover, the findings indicate that CPO significantly drives customers’ social influence engagement and knowledge-sharing engagement. This study contributes theoretically to the CPO literature by further developing its linkages with congruity perceptions and customer engagement. Practical implications of the findings can help hotel managers effectively promote CPO and customer engagement.  相似文献

What does a community‐centric approach to impact assessment look like? That is the central question addressed in this article. Our community‐centric perspective provides an alternative to discipline‐centric approaches to impact assessment that emphasize specific methodological gold‐standards (e.g., randomized controlled trials [RCTs] in development economics). Disciplinary approaches to impact assessment owe their principal allegiance to the discipline's knowledge‐creation norms. Consequently, the concerns, interests, and voices of community members are not fully captured in the impact assessment process. In this article, we flip the conventional perspective to offer a community‐centric view of impact assessment that places the concerns, interests and voices of community members front and center. We present the case for why we need a community‐centric approach to impact assessment and clarify its axiological content, theoretical perspective, and methodological stance. Specifically, we advocate for a relational axiology, a system‐theoretic perspective, and a phenomenological methodology.  相似文献

Nowadays, industrial firms are very much careful to build a green environment by reducing carbon emissions. The government imposes some rules and regulations to provide a better eco-friendly environment. In this study, the cap-and-trade mechanism has been considered in a production model to control the carbon emissions rate. The manufacturers invest in advanced green technology to reduce per unit emissions. As online and offline selling is crucial to any industry for increasing customer demand, the manufacturers sell their products by dual-channel and advertise their products by online channel to make more popular of their products. Keeping these in mind, a sustainable flexible production model with single-type substitutable product production is considered here by imposing a cap-and-tax policy, investing in green technology, and advertising for products. This model is divided into two cases: with and without investment in green technology. The demand of each manufacturer depends upon an online selling price, an offline selling price, and an online advertisement of the product. A classical optimization technique helps to get the optimum strategies for the online selling price, offline selling price, advertisement investment, green technology, cycle time, and production rate. From the numerical study, it is proved that the industry gets 6.97% more profit in the case of green technology investment and the proposed study gives 5.74% more profit than the traditional production system. Sensitivity analysis and managerial insights are performed.  相似文献

Women are generally seen as less inclined to join trade unions. This study matches firm–worker data from the Swedish cigar and printing industries around 1900 and examines information on men and women holding the same jobs; such data are rare but important for understanding gender gaps. The results explain the gender gap in union membership among compositors, but not among cigar workers. Differences in union membership varied considerably across firms, with the largest differences found in low-union-density cigar firms where indirect costs (that is, uncertainty and risk) accrued in particular to women workers. The lack of gender differences in mutual aid membership indicates that women were not hard to organize but avoided organizations associated with greater risk for employer retaliation and uncertain returns according to a cost–benefit analysis.  相似文献
