How communities support innovative activities: an exploration of assistance and sharing among end-users 总被引：3，自引：0，他引：3
This study contributes to our understanding of the innovation process by bringing attention to and investigating the process by which innovators outside of firms obtain innovation-related resources and assistance. This study is the first to explicitly examine how user-innovators gather the information and assistance they need to develop their ideas and how they share and diffuse the resulting innovations. Specifically, this exploratory study analyzes the context within which individuals who belong to voluntary special-interest communities develop sports-related consumer product innovations. We find that these individuals often prototype novel sports-related products and that they receive assistance in developing their innovations from fellow community members. We find that innovation-related information and assistance, as well as the innovations themselves, are freely shared within these communities. The nature of these voluntary communities, and the “institutional” structure supporting innovation and free sharing of innovations is likely to be of interest to innovation researchers and managers both within and beyond this product arena. 相似文献

In this paper we describe how progressive download and adaptive streaming can be combined into a simple and efficient streaming framework. Based on the MPEG-4 file format (MP4) we use HTTP for transport and argue that these two components are sufficient for specifying an open streaming architecture. The client selects appropriate chunks from the MP4 file to be transferred based on (1) the header information (i.e. the “moov” box) in the first part of the file and (2) his observation of network throughput. The framework is completely client driven which allows for better server scalability and reduces signalling overhead. We discuss architecture and implementation issues such as complexity, interoperability and scalability and compare to 3GPP PSS Rel-6 adaptive streaming when appropriate. Measurements from a simple MP4/HTTP streaming client are presented showing that appropriate chunks are selected such that increased reliability is achieved. 相似文献

This contribution aims to lay down the theoretical potential of accompaniment as a phenomenon and developing this point further from a pedagogical perspective. The core assumption is that accompaniment represents both a pedagogically relevant phenomenon of action as well as an essential characteristic of the system. In this sense, accompaniment can be understood as creating a possibility for looking at phenomena of education on a micro and a macro level. Thus, the assumption follows that a central signature of the social system – namely that of inclusion – has already been incorporated by the pedagogically organized system of lifelong learning a long time ago. This finding has far-reaching consequences for levelling the hierarchy between different layers of the education and learning systems. 相似文献

The ability to communicate effectively is an essential skill for graduates of Masters of Business Administration (MBA) programmes; however, as synchronous hybrid learning becomes more common, business schools may find it challenging to assess students’ proficiency in this core area. An additional layer of complexity is added by the burgeoning enrolment of international students in this technology-enriched learning environment. The objective of this exploratory study was to examine the relationships among attendance mode (online vs. on-campus), student nationality (domestic vs. international) and oral communication assessment scores in a synchronous hybrid MBA programme. Quantitative data from 202 hybrid MBA students collected over 12 semesters revealed domestic students were rated as more proficient orators than international students when assessed face-to-face. These results, however, were not replicated when students were assessed in a synchronous online environment. Furthermore, the results indicated that international students received higher scores when their oral communication skills were assessed online compared to face-to-face. Conversely, domestic students who were assessed face-to-face had higher mean scores than the domestic students who were assessed online. The findings are discussed with respect to teaching and learning in hybrid environments, technology-mediated assessment design and accreditation practices in non-traditional programme delivery modes. 相似文献

Individual consumers in the household sector increasingly develop products, services and processes, in their discretionary time without payment. Household sector innovation is becoming a pervasive phenomenon, representing a significant share of the innovation activity in any economy. Such innovation emerges from personal needs or self-rewards, and is distinct from and complementary to producer innovations motivated by commercial gains. In this introductory paper to the special issue on household sector innovation, we take stock of emerging research on the topic. We categorize the research into four areas: scope, emergence, implications for business, and diffusion. We develop a conceptual basis for the phenomenon, introduce the articles in the special issue, and show how each article contributes new insights. We end by offering a research agenda for scholars interested in the salient phenomenon of household sector innovation. 相似文献

Satisfying heterogeneous user needs via innovation toolkits: the case of Apache security software 总被引：3，自引：0，他引：3
Manufacturers customarily provide only a few product variants to address the average needs of users in the major segments of markets they serve. When user needs are highly heterogeneous, this approach leaves many seriously dissatisfied. One solution is to enable users to modify products on their own using “innovation toolkits.” We explore the effectiveness of this solution in an empirical study of Apache security software. We find high heterogeneity of need in that field, and also find that users modifying their own software to be significantly more satisfied than non-innovating users. We propose that the “user toolkits” solution will be useful in many markets characterized by heterogeneous demand. 相似文献

Interrelation between patenting and standardisation strategies: empirical evidence and policy implications 总被引：2，自引：0，他引：2
This paper analyses the relationship between strategies to protect intellectual property rights and their impact on the likelihood of joining formal standardisation processes. It is based on a small sample of European companies. On the one hand, theory suggests that the stronger the protection of own technological know-how, the higher the likelihood to join formal standardisation processes in order to leverage the value of the technological portfolio. On the other hand, companies at the leading edge are often in such a strong position that they do not need the support of standards to market their products successfully. The results of the Probit models to explain the likelihood to join standardisation processes support the latter theoretical hypothesis: the higher the patent intensities of companies, the lower is their tendency to join standardisation processes. 相似文献

Synchronous hybrid delivery (simultaneously teaching on‐campus and online students using Web conferencing) is becoming more common in higher education. However, little is known about students’ emotions in these environments. Although often overlooked, emotions are fundamental antecedents of success. This study longitudinally examined the role of students’ emotions (enjoyment, anxiety, and boredom), perceptions of control, value, and success in synchronous hybrid learning environments. In particular, the investigation assessed students’ self‐reported enjoyment, anxiety, and boredom as predictors of their program achievement and successful technology use. Students were recruited from synchronous hybrid MBA and MPA programs. Control‐value theory of emotions was used as the theoretical framework. Paired samples t‐tests revealed that the achievement domain, compared to the technology domain, yielded higher mean scores for control, value, enjoyment, anxiety, and boredom. In addition, mixed ANOVAs indicated an interaction effect in which group means for program boredom were significantly higher for on‐campus students than for online students. Intercorrelations in each domain showed that perceived success was positively related to enjoyment and negatively related to anxiety and boredom. Technology‐related anxiety was also found to fully mediate the positive effect of control on perceived success in using technology. 相似文献
