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

AbstractThree case studies (Veneto-Cretan shipping of Egyptian-Arab merchandise, Catalan-Venetian cooperation, and Venice acting on behalf of Latin pilgrims) around the activities of the Venetian consul inform an investigation of the cosmopolitan community formed by local groups and foreign nations, and the role of the Venetian consul in this wider community. It will be argued that the Venetian consul was not only a Venetian envoy but also a Mamlūk official and an informal head of the cosmopolitan business community in late medieval Alexandria. 相似文献

Center-based child care has been struggling with poor health and high turnover rates of child care staff and their adverse impact on care quality for decades. Yet little is known about personal and structural antecedents of job resources and job demands that are valid predictors of health and turnover in the child care workforce. Research Findings: This study investigated job resources and job demands among child care staff of different education levels (491 lead teachers and 310 assistant teachers) from Switzerland. Results from t-tests and hierarchical regression analyses indicated slightly higher job resources and job demands for lead teachers than for assistant teachers but similar antecedents of job resources and job demands. Overall, center characteristics shaped job resources and job demands more strongly than staff characteristics. More specifically, job resources were predicted by structural characteristics associated with professionalism in child care work, whereas job demands were primarily dependent on adequate staffing. Practice or Policy: The findings suggest that center characteristics (e.g., work environment and staffing levels) should be targeted in order to increase job resources and reduce job demands, which would in turn promote health and lower turnover rates among child care staff. 相似文献
