This paper investigates the relationship between patenting and publication of research results by university faculty members. Our study adds to the limited evidence on this topic with an empirical investigation based on a panel data set for a broad sample of university researchers. Results suggest that publication and patenting are complementary, not substitute, activities for faculty members. This is not consistent with recent concerns regarding deleterious effects of patenting on the research output of faculty members. Average citations to publications, however, appear to decline for repeat patenters, suggesting either a decrease in quality or restrictions on use associated in patent protection. 相似文献

Changing Patterns in the Middle Management of Higher Education Institutions: The Case of Portugal 总被引:1,自引:0,他引:1
Abstact Much of the writing on higher education in recent years has tended to assume that the new management push in higher education
is both universal and irreversible. This paper, however, presents evidence from Portugal to challenge that assumption. While
elements of the new managerialism are clearly evident in the perceptions and attitudes of academics in charge of the basic
academic units (departments/schools and faculties) in the country’s universities and polytechnics, academic management remains
faced with a complex, contradictory and conflicting set of demands and expectations which is likely to take a considerable
time to resolve. 相似文献

Scientific facts are loaded with values, but, it is argued, this does not viciously compromise the objectivity of scientific claims, because the values that permeate scientific discourse (a) are loaded in turn with facts, (b) are not immune from critical revision, and (c) have changed in the past and continue to be subjected to revision. In science, unlike such enterprises as Scientific Creationism, values are discovered, introduced, tested and challenged in the same way that other aspects of scientific discourse are. All of this makes scientific discourse relevant to the contemporary exploration and critique of human values in general, particularly as more aspects of life become illuminated by science.Research for this paper was made possible in part by RF-CUNY (grant PSC-CUNY 669106). A preliminary version of this paper was given at Universite de Fribourg, Switzerland, May 1990. 相似文献

Three experiments were conducted to examine the effects of map structure, concept quantification, and focus question on dynamic thinking during a Concept Map (CMap) construction task. The first experiment compared cyclic and hierarchical structures. The second experiment examined the impact of the quantification of the header concept in the map. The third experiment explored the effect of the focus question on the map. For all three experiments, the content of the CMaps was assessed for the number of dynamic propositions and the number of quantified concepts. The results show that the cyclic structure, the quantification of the header concept, and the focus question “How” significantly increased dynamic thinking. The studies, the theoretical background, and the implications of the findings are discussed. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 44: 448–465, 2007 相似文献

The voucher model of financing schooling is becoming increasingly common throughout Latin America, with at least 12 countries using vouchers or voucher-like schemes. The present study focuses on the voucher models of Colombia and Chile, which have the most extensive programs of this type and those of the longest standing in the region. Using empirical evidence, the author compares the two models along four evaluative dimensions: educational quality, segregation, choice and socialization. After weighing the successes and weaknesses of each system, he concludes that, among other characteristics, the most effective and equitable voucher model features: (a) a flexible interpretation of educational quality; (b) financial grants which target solely the poor; (c) vouchers which cover the entire cost of tuition; (d) open enrolment at participating schools; (e) the participation of both secular and religious private schools; (f) accessible and meaningful information to parents; and (g) strong systems of accountability. 相似文献

We examine the accuracy of p values obtained using the asymptotic mean and variance (MV) correction to the distribution of the sample standardized root mean squared residual (SRMR) proposed by Maydeu-Olivares to assess the exact fit of SEM models. In a simulation study, we found that under normality, the MV-corrected SRMR statistic provides reasonably accurate Type I errors even in small samples and for large models, clearly outperforming the current standard, that is, the likelihood ratio (LR) test. When data shows excess kurtosis, MV-corrected SRMR p values are only accurate in small models (p = 10), or in medium-sized models (p = 30) if no skewness is present and sample sizes are at least 500. Overall, when data are not normal, the MV-corrected LR test seems to outperform the MV-corrected SRMR. We elaborate on these findings by showing that the asymptotic approximation to the mean of the SRMR sampling distribution is quite accurate, while the asymptotic approximation to the standard deviation is not. 相似文献

Although much attention has been paid to how media use and interpersonal discussion motivate people to engage in political persuasion, and despite recent efforts to study the role of digital media technologies, less is known about the creation of news and public affairs content online. This study sheds light on how online content creation works alongside other communicative behaviors, such as news use and political discussion, to affect attempted political persuasion. Using two-wave panel survey data, we find that political discussion and citizen news creation mediate the relationships between online and traditional news use, on one hand, and attempted persuasion, on the other. Furthermore, strength of partisanship moderates the relationship between content creation and attempted persuasion. Findings are discussed in light of their implications for the political communication and public sphere processes. 相似文献
