The implementation of smart meters in German households by 2032 is a major step in the transition towards an intelligent and connected energy system. Despite of federal legislation providing a structured plan for the nationwide smart meter rollout including basic product requirements, actors within the energy market have the opportunity to take an active part in shaping the market through appealing product offers and hence to create competitive advantage. This study identifies relevant features of smart meters from literature und business practice, and measures customer’s preferences for these features. Results indicate predominantly positive customer evaluations of smart meter features, amongst which the availability of consumption data, the installation price and rental charges as well as time variable tariffs contribute most to overall utility of smart meters. Finally, findings suggest targeting customers by defining strategies to address privacy concerns, to educate about saving potentials as well as to create differentiated pricing schemes.  相似文献

Abusive supervision has received increasing attention in the field. However, few studies have qualitatively reviewed its latest developments. The current paper reviews 48 studies on abusive supervision using content analysis. We identify six emerging trends of abusive supervision, including inconsistency of abusive behaviors, comparison between perceived and objective behaviors, reciprocity, team-level climate, coworker effects, and comparisons between theoretical perspectives. Based on a review of those six trends and some emerging findings, we identify and validate the possible positive effects of abusive supervision from an integrated analysis. We also determine the moderating role that Asian culture plays in differentiating the negative and positive effects of abusive supervision. Specifically, we identify the differences between Asian and Western cultures, and then explore the moral mechanisms (i.e., violation of moral standards, conflict of moral principles) through which abusive supervision may exert positive effects in the Asian cultural context. Finally, we clarify our theoretical implications and provide suggestions for future research.  相似文献

In this essay we consider why American colleges and universities participate in big-time commercialized intercollegiate sports, and how sports came to play such a prominent role on American college and university campuses. We also review how the National Collegiate Athletic Association (NCAA) developed as a body to regulate player safety and transformed itself into an economic regulator, the means by which the NCAA attempts to maintain its control, increase revenues, and reduce costs for college sports programs. We also examine how the organization succeeds in the face of institutional characteristics that imply that its cartel activities would be doomed. Finally, we speculate on what changes might be on the horizon for the NCAA and college athletics.  相似文献

Salespeople assume a key role in defending firms’ price levels in price negotiations with customers. The degree to which salespeople defend prices should critically depend upon their leaders’ influence. However, the influence of leadership on salespeople’s price defense behavior is barely understood, conceptually or empirically. Therefore, building on social learning theory, the authors propose that salespeople might adopt their leaders’ price defense behavior given a transformational leadership style. Furthermore, drawing on the contingency leadership perspective, the authors argue that this adoption fundamentally depends on three variables deduced from the motivation–ability–opportunity (MAO) framework, that is, salespeople’s learning motivation, negotiation efficacy, and perceived customer lenience. Results of a multi-level model using data from 92 salespeople and 264 salesperson–customer interactions confirm these predictions. The first to explore contingencies of salespeople’s adoption of their transformational leaders’ price negotiation behaviors, this study extends marketing theory and provides actionable guidance to practitioners.  相似文献

In 2016, German corporations invested 33.5 billion euros in on-the-job-trainings. Communication trainings, especially those for executives, play an important part in on-the-job-trainings and adult education. This study examines how basics of communication and media studies are used in the praxis of communication trainings. We ask which theories of interpersonal communication are being used in communication trainings for executives and for what reasons trainers choose specific theories. The answer can help us understand how executives view communication processes and which criteria make a theory praticable in the eyes of practitioners.First, we define communication trainings as part of on-the-job training and give an overview of research regarding the use of theories in trainings. Research shows that theories play an important role in communication trainings, but that the trainings lack theoretical depths and complexity. The existing research stems mostly from linguistics; the perspective of communication and media studies is missing. In addition, none of the existing studies considers criteria for a practicable theory.In a second step, the canon of theories of interpersonal communication in communication and media studies is identified via a content analysis of seven textbooks and encyclopedias. Overall, these books present 38 theories of interpersonal communication, but only eight theories are presented in three or more books. These eight theories, among them Symbolic Interactionism (Mead), the Theory of Social Systems (Luhmann) and the Four-Ears-Model (Schulz von Thun), build the canon of theories of interpersonal communication in this study.This canon is the basis for the main part of our study. Sixteen communication trainers were interviewed, using the method of qualitative expert interview. The trainers answered questions regarding their professional background, typical courses of training, their goals in trainings, the role of theories in trainings, requirements of the executives being trained and the exchange between colleagues in the occupational field.Results show that trainers use about 15 to 20% of the training time to convey theoretical basics. The Four-Ears-Model by Schulz von Thun dominates the examined trainings. Scientists regard this communication-psychological model as being rather popular scientific. Still, every interviewed trainer uses it. This finding shows that most trainers regard communicational misunderstandings as a result of the four-dimensional character of a message (Who is the sender? Why is he talking to me like that? What are the facts about? What shall I do, think, feel based on the message?). The Communication Axioms by Watzlawick are used as the second most common approach.Apart from theories of interpersonal communication, the trainers mentioned several psychological methods and approaches with therapeutic traits, like Transaction Analysis (Berne) or Active Listening (Rogers).The explorative findings suggest that the trainers chose the theories they use—especially the Four-Ears-Model and Communication Axioms—because it is easy to interlock these theories and the praxis of communication trainings, because they are comprehensible and easy to use in examples, and because they show the relativity of communication processes. Moreover, trainers use theories to explain human behavior and the sources for misunderstandings.These criteria alone do not explain the trainers’ theory choices, though. It became clear in the interviews that factors of socialization, like advanced training for the trainers, play a major role in influencing their training content. Trainers teach the theories which they themselves learned in further education programs becoming a trainer, and they barely look out for new and/or alternative theories.We recommend that communication trainers look for other theories in communication and media studies, like the Symbolic Interactionism. This theory complies with the trainers’ criteria for good theories. Communication and media scholars on the other hand should work together with educational institutions and advanced training to improve the transfer of their theories into the praxis of communication trainings.  相似文献

The fact that jurisdictional consolidation overcomes externality problems in the provision of local public goods is one of the best-known benefits of consolidation in the theoretical literature. Nevertheless, previous studies provide little evidence of how public service spillover effects influence consolidation decisions. This study empirically tests the hypothesis that spillovers induce consolidation, using voting data on the consolidation of Japanese municipalities. The extent of spillovers is measured by estimating the demand function for public goods with externalities. It is found that residents of the municipalities that can internalize a large amount of public goods spillovers through municipal consolidation tend to favor consolidation. This result supports the theoretical inference that spillovers in local public goods affect utility gains from jurisdiction integration, thus serving as one of the key impetuses for boundary reform. Moreover, after controlling for the spillover effects, economies of scale, population share, differences in median income, and unconditional grants can help explain consolidation preference.  相似文献
