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

The empirical evidence from the extant literature has been equivocal regarding the influence exerted by different ownership types on corporate social responsibility (CSR), especially in developing countries such as India characterized by institutional voids. We use a longitudinal panel dataset of 500 large Indian companies to test a model of corporate ownership forms as key determinants of CSR engagement in India. Based on neo-institutional theory, our model of CSR determinants investigates the roles of three salient aspects of ownership namely multinational ownership/affiliation, state ownership and family ownership and control, after controlling for the influence of firm size, firm age, leverage, the availability of slack resources, profitability and various governance attributes. Our ordered logit regressions indicate strong support for the role of multinational ownership and family control and management in promoting higher levels of CSR engagement. Contrary to expectations, public sector ownership appeared to negatively impact CSR engagement. We offer our conjectures on this anomalous finding and the research possibilities it opens up. 相似文献

This study focuses on female and male students who succeed in engineering programmes in Sweden, and why they have success. Data were collected through a questionnaire sent to all engineering students in Sweden registered for their seventh semester during year 2012 and about 30 % of the students in the cohort responded on several questions. The answers were then analysed and interpreted using Pierre Bourdieu’s theory and the concept of capital. The female-students as well as the male-students emerged as homogeneous groups, but SPSS-clustering shows differences and similarities between four female student-profiles and five male students-profiles. The female students who come to graduate as engineers have experiences and resources that seem to be fruitful: well-educated parents, positive attitudes to the engineer students’ traditions, and a positive view of the engineering profession. In addition, they value the traditional teaching with lectures and self-studies. They seem not to have been inspired by compulsory school teaching or teachers there. The male students have the same experiences and resources but there are differences. Among female students, a profile emerges which is absent among the male students and which emphasises the importance of doing good for society, people, and the environment in their future professional roles. Among male students, the student profiles which emerge include one with a primarily practical and technical capital despite the lack of a high degree of educational or scientific capital. 相似文献

Design and problem solving are central to technology and have distinguished learning in technology from other curriculum areas. This research investigated how expert technologists learn design and problem solving through experience. Data was collected from four expert technologists and this information was analysed using learning theories that focus on learning through experience—that is experiential learning theory, situated cognition, distributed cognition and activity theory. This framework of analysis provided evidence that learning through experience is central to these experts’ development and justify a broader construct of experience than normally associated with hard materials. This information supports curriculum development in hard materials technology that employs a wide range of experiences and provides justification for curriculum developers and teachers to justify, inform and develop effective design and problem solving learning programmes focussed on a broadened construct of experience. 相似文献

Technology education is a new school subject in comparison with other subjects within the Swedish compulsory school system. Research in technology education shows that technology teachers lack experience of and support for assessment in comparison with the long-term experiences that other teachers use in their subjects. This becomes especially apparent when technology teachers assess students’ knowledge in and about technological systems. This study thematically analysed the assessment views of eleven technology teachers in a Swedish context. Through the use of in-depth semi-structured qualitative interviews, their elaborated thoughts on assessing knowledge about technological systems within the technology subject (for ages 13–16) were analysed. The aim was to describe the teachers’ assessment views in terms of types of knowledge, and essential knowledge in relation to a progression from basic to advanced understanding of technological systems. The results showed three main themes that the interviewed teachers said they consider when performing their assessment of technological systems; understanding (a) a system’s structure, (b) its relations outside the system boundary and (c) its historical context and technological change. Each theme included several underlying items that the teachers said they use in a progressive manner when they assess their students’ basic, intermediate and advanced level of understanding technological systems. In conclusion, the results suggest that the analysed themes can provide a basis for further discussion about defining a progression for assessing students’ understanding about technological systems. However, the findings also need to be examined critically as the interviewed teachers’ views on required assessment levels showed an imbalance; few students were said to reach beyond the basic level, but at the same time most assessment items lay on the intermediate and advanced levels. 相似文献

The subject of design and technology was introduced to the curriculum for high schools in China 10 years ago. However, the teaching and learning of this subject have become difficult for both teachers and students because there is a lack of qualified teachers with design background to deliver this subject in a way to stimulate the learning interests of the students. This paper presents a research that is aimed at improving this situation by integrating the teaching and learning of design and technology within a computational environment as part of social networks sites. The purpose is to enable the collaboration among the students and interaction between teachers and students. In this research, a series of investigations were conducted, by following through several taught subjects in design and technology in prominent high schools in China. Based on these investigations, a theoretical framework for web-based design learning and teaching system in the style of social networking is developed, implemented and tested, emphasizing three features of design: innovation, collaboration, and interaction. This framework has been tested among high school students and teachers in a high school in Nanjing. It identified and validated necessary techniques and design features required to make an education-related social networking site effective and affective for the students and teachers. The results of this research indicated that social networking sites have significantly positive values in design education, especially for the collaboration and interaction on the subject of design and technology. 相似文献

The paper explores the impact of the internet on students and their enhancement of their Identity and culture in the world of globalization. It is based on two stages; a theoretical background in the literature that provides criteria for examining the issue of the study. Then, the analytical study is done to the collected data. The paper incorporates two methods of data collection; a questionnaire survey to measure the instructors’ perception of how students should reflect the identity and local culture in their projects in the internet era, and statistical analysis of students’ implementation of cultural knowledge and identity features in their graduation projects in the new millennium before the usage of internet in the design education in the interval of 2001–2007 and after the usage of internet the interval between 2008 and 2015. Consequently, the paper is designed to generate both statistical quantitative and qualitative data. Despite the apparent impact of Globalization and internet based education on abandoning individual identity, yet it might lead to opening new horizons in front of dealing with cultural identity and heritage with a contemporary vision that integrates with nowadays architecture and at the same time refer to the unique identity. 相似文献

The design and development processes of instructional materials might be considered simple and clear because the pre-established instructional goals can lead the way. However, in practice, there are lots of issues to be considered during these processes. The quality of the material, appropriate visual design, usability, and acceptable amount of cognitive load are some of these issues. On the other hand, an instructional material needs to be as original as possible. In this study, we focused on the creativity of the instructional materials designed and developed by second year students from the Computer Education and Instructional Technologies (CEIT) department. We divided students into two groups: (1) CEIT students designing and developing materials about Information Technology (IT); (2) CEIT students designing and developing materials about Math. The main aim of this study is to understand how CEIT students’ instructional materials differ when they design and develop materials, which are out of their field of experience. In other words, we tried to compare how the creativity of materials change when students create materials with familiar domain (IT) in comparison to unfamiliar domain (Math). Students worked on ten instructional materials such as digital story, animation, and worksheet for 14 weeks. The materials of students were evaluated in terms of creativity, and then they were interviewed. The students worked in groups of 4–5, and during the material development period, we as researchers observed and took notes about the whole process. The findings indicated that materials developed in familiar domain were higher in creativity than those of the unfamiliar. Students’ explanations of creativity and their evaluations about the process helped us to understand the reasons of the produced materials’ creativeness. Technical skills, authentic contributions, material type, and the boundaries of the content or familiarity were found as the primary factors affecting the design and development of creative instructional materials. 相似文献
