Household sector innovation is significant in scale and scope. Thus far, it has been studied in isolation and with mixed evidence regarding the role of personal resources (consumers' income and discretionary time). We recognize that household sector innovation is embedded in the broader phenomenon of do-it-yourself (DIY) by consumers, as the literature reveals conceptual similarities, parallel motivations, and antecedents. The main distinction is that, whereas DIY goods may replicate existing products, household sector innovation is restricted to goods embodying a novel function. We explore if studying household sector innovation and DIY in an integrated framework helps to resolve previous inconsistent evidence on the role of personal resources. Based on a neoclassical model in which agents optimize their time allocation, we hypothesize that income and discretionary time positively relate to their DIY output, but—given that agents develop DIY goods—we hypothesize that income negatively relates to innovation. For discretionary time, we formulate a research question regarding its effect on innovation which we answer empirically. Our findings suggest that consumers with more personal resources derive more process benefits from DIY but that these benefits crowd out individuals' focus on the function of their objects, hence, the likelihood of developing innovations. Survey data from the United Arab Emirates (n = 2728) confirm our suppositions, showing that the relationship between personal resources and household sector innovation is more refined than suggested by previous studies. 相似文献

This article examines the digital divide in terms of access and the cultural use purposes of the Internet in Finland, the United Kingdom, and Greece. The analysis is based on data from Finnish, British, and Greek sections of Eurobarometer collected in 2013 (N = 3,009). Separate measures for class and status are applied in the analysis. The findings indicate that both access to and use of the Internet for cultural purposes are affected by a number of interdependent factors, whose effects and strengths vary significantly among the countries. 相似文献

This paper studies the evolution of the photovoltaics industry in Australia, Germany and Japan taking a comparative perspective. A modification of the sectoral innovation system framework is used to discuss: knowledge and technologies, actors and interactions, institutions and funding, development of markets and technological structure, as a way to understand the changes. In the process of transition from niche to mass production, national players have specialised in different activities, and the institutions’ building block has been a key determinant. In the case of Australia, it is also the least developed area which ultimately exposes the country to losing its innovation benefits. 相似文献

What is the sky? Where is it? How high is it? What lies above the sky? I am sure that you have asked questions like these. They are very difficult to answer, aren't they?Perhaps we can answer some of these questions now. What is the sky? It is vast space. In the sky there is the sun, the moon, and all the stars.Scientists have always wanted to know more about space. They use telescopes to obtain information. But this 相似文献

塞林格一直被认为西方神秘主义的影响,而禅宗方面却常被忽略。佛教禅宗对塞林格施以极大影响,他自己也十分向往东方哲学,尤其是佛教禅宗。这方面在他的代表作《麦田里的守望者》中表现的很明显。在这部小说中,霍尔顿的麦田里守望者的愿望,在于要阻止孩子们堕落到虚伪的成人世界。这正如佛教僧侣普渡众生,使人们超脱令人厌恶的世俗世界。 相似文献

Learning a language is much more than learning its vocabulary and grammar rules, but also culture, and every culture in each nation has distinct characteristics that made it different from every other culture. This thesis begins with the relationship of language and culture, then analyses the present situation of culture-introduction in the English teaching, explains and points out its necessity and great significance, further puts forward some effective ways of culture-introduction in the English teaching. 相似文献

We review the recent progress in the emerging area of devices and circuits operating on the basis of ionic currents. These devices operate at the intersection of electrochemistry, electronics, and microfluidics, and their potential applications are inspired by essential biological processes such as neural transmission. Ionic current rectification has been demonstrated in diode-like devices containing electrolyte solutions, hydrogel, or hydrated nanofilms. More complex functions have been realized in ionic current based transistors, solar cells, and switching memory devices. Microfluidic channels and networks—an intrinsic component of the ionic devices—could play the role of wires and circuits in conventional electronics. 相似文献

The rapid spread of the 1889-1890 influenza epidemic was widely reported in the periodical press. As Londoners read that another European capital had succumbed, they were struck that the illness was not only travelling as fast as the news, but was also moving along the same routes. Although medical science quickly resolved that a germ was the cause of the illness, its mild nature but widespread social impact lead many to suspect that it was actually caused by newspaper hype. This link between the press and the illness made the epidemic seem a curious symptom of the modern communications technologies that increasingly defined the age. 相似文献

Do world-leading researchers from developing countries contribute to upgrading locally, or do they disengage from the local context? The paper investigates the scientific collaborations of university-based science and technology researchers in the database of the South African National Research Foundation (NRF), and analyses the co-authorships of researchers who were ranked by the NRF during the 2001-2007 period. To establish the extent to which a researcher can access knowledge outside the South African academic science and technology research community, and share it inside that community, we develop a measure of ‘gatekeeping’. The evidence suggests that there is not a local/global trade-off in knowledge creation in academia in the developing world, and that the world-leading researchers in developing countries may play an especially important role as conduits of new knowledge in their country. 相似文献
