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

We explore how a firm’s knowledge structure characteristics and market identity—as reflected in its position in the industry value chain and market status—influence knowledge-based alliance (KBA) formation. We propose that a firm’s propensity to form KBAs is affected by the congruence (or misalignment) between its knowledge structure characteristics (i.e., knowledge depth and scope) and the role it plays in the industry, as demanded by its position in the value chain. We further argue that while a firm’s market status can amplify the positive effect of the congruence, thereby enhancing a firm’s proclivity to form KBAs, being prominent can also hurt a firm when it faces a misalignment between its knowledge structure characteristics and externally induced expectations related to its value chain position. We validate our arguments using panel data on 1051 firm-year observations for 197 firms patenting in the global fuel cell industry for the period 1999–2009. By developing a richer understanding of the relationship between a firm’s knowledge-based resources and KBA formation, we answer the call for a better understanding of how and when firms can leverage their internal knowledge configurations to improve their proclivity to form alliances.  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

Much of the public understanding of science literature dealing with fictional scientists claims that scientist villains by their nature embody an antiscience critique. I characterize this claim and its founding assumptions as the "mad scientist" trope. I show how scientist villain characters from the science fiction television series Doctor Who undermine the trope via the programme's use of rhetorical strategies similar to Gilbert and Mulkay's empiricist and contingent repertoires, which define and patrol the boundaries between "science" and "non-science." I discuss three such strategies, including the literal framing of scientist villains as "mad." All three strategies exclude the characters from science, relieve science of responsibility for their villainy, and overtly or covertly contribute to the delivery of pro-science messages consistent with rationalist scientism. I focus on scientist villains from the most popular era of Doctor Who, the mid 1970s, when the show embraced the gothic horror genre.  相似文献

Darwin came to realize that he could never devise an experiment that would demonstrate the development of new species by crossing hybrids. Instead, he turned to the problem of sterility within a species. The difference between Darwin's experimental and theoretical approach and that of French scientists working in the Muséum d'Histoire Naturelle in Paris can be shown most vividly by tracking Darwin's experiments in botany and his interest in those of Charles Naudin on hybrid plants. In his discussion of Mendel, Robert Olby has provided an interesting analysis of Naudin's hereditary concepts. I have approached some of the same work here with an emphasis on the question of sterility raised by Darwin, not simply between hybrids but within members of the same species and the light that he thought this could throw on both heredity and the origin of species.  相似文献

Arguments regarding the relationship between media discourse and public opinion have raged for decades, if not centuries. COmparing media coverage of biotechnology between 1992 and 2001 in two national newspapers with national survey data collected in early 2003, an argument is made that a general one-dimensional media effect is not occurring within the US public regarding media discourse. Given the multivalent characteristics of the media and the interpretive filters used by audiences - including ignoring information - even strong slants by the presumed opinion-leading press (the New York Times and the Washington Post) do not predict public opinion on a nascent issue such as biotechnology. While some observations show these mirrors to be ephemeral.  相似文献

This study employs digital methods in conjunction with traditional content and discourse analyses to explore how the US President Donald Trump conducts diplomacy on Twitter and how, if at all, diplomatic entities around the world engage in diplomatic exchanges with him. The results confirm speculations that Trump’s diplomatic communication on Twitter disrupts traditional codes of diplomatic language but show little evidence that new codes of diplomatic interactions on social media are being constructed, given that other diplomatic entities around the world mostly remain within the confines of traditional notions of diplomacy in (not) communicating with Trump on Twitter.  相似文献

This paper addresses the issue of public perception of modern biotechnology in the Netherlands. Contrary to expectations, data from the 1999 Eurobarometer on biotechnology indicate that the position of the Dutch public in general is rather ambiguous, which is in contrast to many of its neighboring countries. The issue is described in terms of differences between the Netherlands and other European countries on political-economic, social-cultural, or media coverage indicators. On many indicators, the Dutch population differs from that of other European countries, and the Dutch opinion-leading media present a rather balanced perspective on modern biotechnology.  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

In the August 2020 issue of Clinical Chemistry and Laboratory Medicine, Giuseppe Lippi and Mario Plebani proposed a definition of laboratory medicine, which ends with this sentence: “The results of these measurements are translated into actionable information for improving the care and/or maintaining the wellness of both a single individual and an entire population”. Nevertheless, the selfishness of individuals may, sometimes, jeopardize the interest of whole populations. The virtue of justice being within the reach of the entire human community more than of single individuals, the final sentence in the definition proposed by Giuseppe Lippi and Mario Plebani, should therefore, in our view, be rewritten, less selfishly, for example like this: “For a given investment, these measurements are preferably made when they bring as much beneficence, and non-maleficence, as possible to the whole population”.  相似文献

In their race to provide the ultimate guide to the moon, two 17th-century astronomers proposed lunar maps and nomenclatures that they hoped would gain international currency. But the names we use today were those proposed by the Jesuit, a friend of Galileo's persecutors, in a book whose purpose was to refute the Copernican system once and for all. We now believe that Riccioli was wrong about the universe, but why do we still use his nomenclature? The keys to this foundational visual debate in astronomical image-making are the moon maps themselves.  相似文献

Scholars have recently highlighted the promise of open innovation. In this paper, we treat open innovation—in it's different forms and manifestations—as well as internal or closed innovation, as unique governance forms with different benefits and costs. We discuss how each governance form, whether open or closed, is composed of a set of instruments that access (a) different types of communication channels for knowledge sharing, (b) different types of incentives, and (c) different types of property rights for appropriating value from innovation. We focus on the innovation “problem” as the central unit of analysis, arguing for a match between problem types and governance forms, which vary from open to closed and which support alternative forms of solution search. In all, the goal of this paper is to provide a comparative framework for managing innovation, where we delineate and discuss four categories of open innovation governance forms (markets, partnerships, contests and tournaments and user or community innovation) and compare them with each other and with two internal or closed forms of innovation governance (authority and consensus-based hierarchy).  相似文献

To the keen observer of American political and medical history, a disturbing set of debates surrounded the sanity of free Black residents of the United States of America after the publication of the controversial 1840 census returns on race and insanity. This article analyzes how the census became a battlefield where physicians and other commentators fought over—and thus shaped—various political meanings of Black insanity before and after the American Civil War, up until the 1890s, as the South underwent a massive political and social transformation, from slavery to emancipation. It also highlights the arguments raised by authors such as James McCune Smith and Ramón de la Sagra who attempted to disprove the returns shortly after their publication, and whose arguments contributed to efforts to combat scientific racism.  相似文献

Research and public policy on academic entrepreneurship are largely based on the assumption that faculty members start businesses to commercialize inventions that have been disclosed to university administrators and have been patented. In this paper, we analyze a sample of 11,572 professors and find that much academic entrepreneurship occurs outside the university intellectual property system. Specifically, about 2/3 of businesses started by academics are not based on disclosed and patented inventions. Moreover, we show that individual characteristics, departmental and organizational affiliations, and time allocation of academics that have started business outside the IP system are different from those of academics that have started businesses to exploit disclosed and patented inventions. We discuss the implications for research on and the practice of academic entrepreneurship.  相似文献

In this paper, we analyze the extent to which University-Level Support Mechanisms (ULSMs) and Local-Context Support Mechanisms (LCSMs) complement or substitute for each other in fostering the creation of academic spin-offs. Using a sample of 404 companies spun off from the 64 Italian Science, Technology, Engineering, and Mathematics universities (STEM universities) over the 2000–2007 period, we show that the ULSMs’ marginal effect on universities’ spin-off productivity may be positive or negative depending on the contribution offered by different LCSMs. Specifically, in any given region, ULSMs complement the legislative support offered to high-tech entrepreneurship whereas they have a substitution effect with regard to the amount of regional social capital, regional financial development, the presence of a regional business incubator, regional public R&D expenses as well as the level of innovative performance in the region. Results support the idea that regional settings’ idiosyncrasies should be considered for universities to develop effective spin-off support policies. This paper contributes to the debate on the evaluation of economic policies supporting entrepreneurship.  相似文献
