    Research productivity in the internet era
    (Springer, 2006) Barjak, Franz
    The present study investigated the relationship between the use of different internet applications and research productivity, controlling for other influences on the latter. The control variables included dummies for country, discipline, gender and type of organization of the respondent; as well as variables for age, recognition, the degree of society-related and career-related motivation for research, and the size of the collaboration network. Simple variance analyses and more complex negative binomial hurdle models point to a positive relationship between internet use (for personal communication, information retrieval and information dissemination) and research productivity. However, the results should be interpreted with caution as it was not possible to test the role of the internet against other pre-internet tools which fulfil the same functions. Thus instance it may not be the use of e-mail per se, but the degree of communicating with colleagues that makes a productive scientist.

    The Future of e-Research Infrastructures
    (25.06.2009) Schroeder, Ralph; Meyer, Eric; Eccles, Kathryn; Kertcher, Zack; Barjak, Franz; Hüsing, Tobias; Robinson, Simon
    In this paper, we present selected results of a systematic study of different types of e-Research infrastructures. The paper is based on ongoing research to compare a range of e-Infrastructures of broad diversity focusing on: geographical diversity, representing efforts from around the globe; disciplinary diversity, including the natural sciences, social sciences and humanities; organizational diversity, for example, multi-institutional or federated; diverse levels of maturity, from those in the planning stage to those with a well-established user base; and diverse types of target user communities such as specialized niche, discipline-wide, or generic infrastructures. In presenting six initial cases, we discuss some general features that distinguish between different types of infrastructures across different fields of research. Previous analyses of e-Infrastructures have focused on the parallels between these infrastructures and the major infrastructures in society that support national populations. What our cases highlight instead is that e-Infrastructures consist of multiple types of overlapping and intersecting socio-technical configurations that serve quite diverse needs and groups of users. Indeed, the very term ‘infrastructures’ may be misleading insofar as it connotes support of whole communities of researchers on a large scale, which is currently still premature. The paper derives implications of this heterogeneity for the future outlook on e-Infrastructures.

    International collaboration, mobility and team diversity in the life sciences: impact on research performance.
    (Taylor & Francis, 2008) Barjak, Franz; Robinson, Simon
    The combination of knowledge and skills from different backgrounds or research cultures is often considered good for science. This paper describes the extent to which academic research teams in the life sciences draw on different national knowledge pools and how this is related to their research performance. We distinguish between international collaboration between research teams and international mobility leading to team diversity, where scientists with a background in another country work as members of a team over time. Our findings confirm previous results on the positive relationship between international collaboration and team performance. Moreover, we show that the most successful teams have a moderate level of diversity: maximizing diversity does not maximize performance. These results have implications for research team management and for research policy, in particular pointing out a need for adequate integration support to mobile scientists.

    The role of the Internet in informal scholarly communication
    (2006) Barjak, Franz
    The present analysis looks at how scientists use the Internet for informal scientific communication. It investigates the relationship between several explanatory variables and Internet use in a cross-section of scientists from seven European countries and five academic disciplines (astronomy, chemistry, computer science, economics, and psychology). The analysis confirmed some of the results of previous U.S.-based analyses. In particular, it corroborated a positive relationship between research productivity and Internet use. The relationship was found to be nonlinear, with very productive (nonproductive) scientists using the Internet less (more) than would be expected according to their productivity. Also, being involved in collaborative R&D and having large networks of collaborators is associated with increased Internet use. In contrast to older studies, the analysis did not find any equalizing effect whereby higher Internet use rates help to overcome the problems of potentially disadvantaged researchers. Obviously, everybody who wants to stay at the forefront of research and keep up-to-date with developments in their research fields has to use the Internet.

    A statistical analysis of the web presences of European life sciences research teams
    (2008) Barjak, Franz; Thelwall, Mike
    Web links have been used for around ten years to explore the online impact of academic information and information producers. Nevertheless, few studies have attempted to relate link counts to relevant offline attributes of the owners of the targeted Web sites, with the exception of research productivity. This article reports the results of a study to relate site inlink counts to relevant owner characteristics for over 400 European life-science research group Web sites. The analysis confirmed that research-group size and Web-presence size were important for attracting Web links, although research productivity was not. Little evidence was found for significant influence of any of an array of factors, including research-group leader gender and industry connections. In addition, the choice of search engine for link data created a surprising international difference in the results, with Google perhaps giving unreliable results. Overall, the data collection, statistical analysis and results interpretation were all complex and it seems that we still need to know more about search engines, hyperlinks, and their function in science before we can draw conclusions on their usefulness and role in the canon of science and technology indicators.

    e-Infrastructure adoption in the social sciences and humanities: cross-national evidence
    (12.09.2008) Barjak, Franz; Lane, Julia; Poschen, Meik; Procter, Rob; Robinson, Simon; Wiegand, Gordon
    This paper is a first attempt to describe and compare the adoption of e-Infrastructure across the UK, continental Europe, and the USA in the social sciences and humanities. A survey of early adopters identified three differences across these countries, each potentially affecting adoption: funding approaches, the technical configuration of projects, and research support. Our findings also suggest that the sustainable adoption of e-Infrastructure co-varies with the role of intrinsic and extrinsic motivations and the involvement of other people in the adoption decision.

    Case Studies of e-Infrastructure Adoption
    (SAGE, 2009) Barjak, Franz; Lane, Julia; Kertcher, Zack; Poschen, Meik; Procter, Rob; Robinson, Simon
    This article reports results from a study of e-Infrastructure adoption in the social sciences and humanities (SSH). The authors find that bridging barriers between computer and domain scientists is of key importance. In particular, SSH communities have to be accepted as being distinct and not suited to a ‘‘one size fits all’’ strategy of e-Infrastructure diffusion. Sustainability was also a core issue, whereas barriers to resource sharing could mostly be resolved with technological solutions, and skills and training activities are a reflection of the general ‘‘user dilemma.’’ The authors’ recommendations to European Union (EU) policy makers point the way to promoting e-Infrastructure development and wider application in the SSH.
