Relationship between R&D expenditures and publication output for U.S. colleges and universities     

Paul R. McAllister  Deborah Ann Wagner 《Research in higher education》1981,15(1):3-30

Two large independent sources of data, NSF's University Science Statistics Program Integrated Data Base and CHI Research's bibliometric data base, are brought together in a comprehensive study of the relationships among research resources, as measured by R&D expenditures, and research output, as measured by the quantity and visibility of scientific journal articles. The study is based on approximately 500 U.S. colleges and universities. For each of 11 fields of science, there is strong indication of a linear relationship between R&D expenditures and number of papers. The evidence also indicates a positive relationship between number of cites received per paper and number of papers published, but only for papers published in the basic research journals of the fields of chemistry, physics, and biology.  相似文献

(Trans)lating Identity: Exploring Discursive Strategies for Navigating the Tensions of Identity Gaps     

Phillip E. Wagner  Benjamin L. Compton 《Communication quarterly》2016,64(3):251-272

This study explored the formation and expression of gender identity among 19 self-identified transgender individuals through the use of qualitative, in-depth interviews. Through the lens of the Communication Theory of Identity (CTI), we examined how trans* individuals form and perform gender identity, the tensions produced between identity frames, and the discursive strategies used to navigate those tensions. We identified the manifestation of three specific identity gaps: personal-enacted, personal-relational, and enacted-relational. Furthermore, we discovered four discursive strategies previously recognized for navigating tensions that emerge from identity gaps: closeted enactment, passing, disengagement, and label changing, and we identified a fifth discursive strategy—hyper-engagement—used to navigate these tensions. Results revealed that these identity layers and discursive strategies collaboratively manifest and coalesce in response to specific communicative contexts. Our results are discussed within the resounding call for greater understanding of trans* identity formation and expression.  相似文献   

On the relationship between environmental management, environmental innovation and patenting: Evidence from German manufacturing firms   总被引：1，自引：0，他引：1  

Marcus Wagner   《Research Policy》2007,36(10):1587-1602

This paper analyses empirically the relationship between environmental innovations, environmental management and patenting. In particular it tests a number of propositions on how environmental management systems and the interaction with environmentally more or less concerned stakeholders are associated with the probability of firms to pursue innovation in general (measured as patenting behaviour) and specifically environmental innovation (measured based on firm self-assessment and through patent data). In applying a negative binomial as well as binary discrete choice models the relationship is studied using data on German manufacturing firms. As a novel and important insight, the study finds that environmental innovation can be meaningfully identified using patent data and that environmental innovation defined this way is less ubiquitous than self-reported environmental innovation. It also reveals that the implementation level of environmental management systems has a positive effect exclusively on environmental process innovation, whereas it is negatively associated with the level of a firms’ general patenting activities. For environmental product innovation and patented environmental innovations a positive relationship with environmentally concerned and a negative link with environmentally neutral stakeholders is found.  相似文献   

Laboratory medicine in pandemic of COVID-19

After the outbreak in China in the year 2019, severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) quickly spread around the world causing a protracted pandemic. Approximately one-third of infections appear to be asymptomatic. Symptomatic disease is characterized primarily by symptoms of respiratory tract infection of varying severity. But Coronavirus Disease 2019 (COVID-19) is much more than an acute respiratory disease because SARS-CoV-2 affects many organs inducing a vast number of symptoms such as cardiovascular, neurological, gastrointestinal, dermatological, with numerous complications. Short and long-term effects of infection, severe ones, and especially mild forms of the disease which affect a huge number of patients need to be further investigated. Laboratory medicine has a crucial role in early diagnosis of the disease, recognition of the patients who need hospital care, and close monitoring of hospitalized patients to timely identify associated clinical complications as well as follow-up of patients with long-term COVID-19.  相似文献   

Learning to be prejudiced: A test of unidirectional and bidirectional models of parent–offspring socialization     

Jos-Miguel Rodríguez-García  Ulrich Wagner 《Int J Intercult Relat》2009,33(6):516-523

According to Allport's (1954) model of socialization of prejudice the level of prejudice of parents and their offspring should co-vary due to the offspring's adaptation to the parents’ attitudes. Available empirical studies and literature reviews support Allport's assumption. Modern models of socialization give reason to extend Allport's unidirectional influence model to a bidirectional perspective which assumes that parents influence their offspring's attitudes and are simultaneously influenced by them. In a cross-sectional study, 408 parent–offspring dyads (64% female parents, 55% female offspring, mean age of children = 16.47 years, SD 1.87, parents = 42.08 years, SD 7.08) from the ethnic majority population in Costa Rica were asked about their prejudice towards immigrants and ethnic minorities in Costa Rica. Using structural equation modelling, unidirectional and bidirectional models of prejudice determination were tested. The data clearly support the unidirectional model of prejudice transmission from parents to offspring, even if moderator effects of sex, age, and importance of contact are taken into account.  相似文献

In support of a functional definition of interaction     

Ellen D. Wagner 《The American journal of distance education》2013,27(2):6-29

Abstract

A common theme in the distance education literature is that delivery technologies with the potential for real‐time interactivity will improve both the image and practice of distance education. Although there appears to be a growing acceptance of a causal relationship between system interactivity and instructional interaction, neither concept has been clearly or functionally defined. This article discusses several systems models and relates them to the contexts of instructional delivery, instructional design, instructional theory, and learning theory in an attempt to establish conceptual parameters for the function of interaction.  相似文献

Does immigration background matter? How teachers’ predictions of students’ performance relate to student background     

Axinja Hachfeld  Yvonne Anders  Sascha Schroeder  Petra Stanat  Mareike Kunter 《International Journal of Educational Research》2010,49(2-3):78-91

Accurate teacher evaluations of student performance are crucial for effective teaching. This study examined whether students’ immigration and language background affect teachers’ evaluations. Multilevel analyses tested whether teachers overestimate the performance of immigrant relative to that of non-immigrant students. As part of the German PISA 2003 assessment, 305 teachers predicted the performance of seven of their students on two mathematics problems of different linguistic complexity. Results revealed an interaction effect of students’ language background and linguistic complexity of the problem on teachers’ predictions. Teachers overestimated the performance of bilingual students more than the performance of monolingual immigrant or non-immigrant students on a linguistically complex problem. Teachers need to consider both students’ language background and linguistic demands of the material used to appropriately support bilingual students.  相似文献
