The increasing rate of outbreaks in humans of zoonotic diseases requires detailed examination of the education, research, and practice of animal health and its connection to human health. This study investigated the collaboration network of different fields engaged in conducting zoonotic research from a transdisciplinary perspective. Examination of the dynamics of this network for a 33-year period from 1980 to 2012 is presented through the development of a large scientometric database from Scopus. In our analyses we compared several properties of these networks, including density, clustering coefficient, giant component, and centrality measures over time. We also elicited patterns in different fields of study collaborating with various other fields for zoonotic research. We discovered that the strongest collaborations across disciplines are formed among the fields of medicine; biochemistry, genetics, and molecular biology; immunology and microbiology; veterinary; agricultural and biological sciences; and social sciences. Furthermore, the affiliation network is growing overall in terms of collaborative research among different fields of study such that more than two-thirds of all possible collaboration links among disciplines have already been formed. Our findings indicate that zoonotic research scientists in different fields (human or animal health, social science, earth and environmental sciences, engineering) have been actively collaborating with each other over the past 11 years.

A recent major shift has broadly impacted the evolution of electronic commerce: Web 2.0. This paradigm shift represents the change of the Internet from a market for goods and services to a socially centered and user-driven marketplace. The authors argue that by applying the fundamental principles of basic psychological need theory, we can better understand how the Web 2.0 technologies

Foodborne disease outbreaks are increasingly being seen as a greater concern by public health authorities. It has also become a global research agenda to identify improved pathways to coordinating outbreak detection. Furthermore, a significant need exists for timely coordination of the detection of potential foodborne disease outbreaks to reduce the number of infected individuals and the overall impact on public health security. This study aimed to offer an effective approach for coordinating foodborne disease outbreaks. First, we identify current coordination processes, complexities, and challenges. We then explore social media surveillance strategies, usage, and the power of these strategies to influence decision-making. Finally, based on informal (social media) and formal (organizational) surveillance approaches, we propose a hybrid information network model for improving the coordination of outbreak detection.

New theoretical and practical approaches were used to determine the outcome of complex interorganizational networks during the 2009 H1N1 outbreak in Australia. Seventy health professionals from different skill sets and organizational positions who participated in the 2009 swine influenza H1N1 outbreak in Australia were surveyed. Interviews were designed to collect both qualitative and quantitative data to build a comprehensive and in-depth understanding of the dynamics of interorganizational networks that evolve during the coordinated response to the H1N1 outbreak. Three main components of network theory, ie, degree centrality, connectedness, and tie strength, were used to construct a performance model for assessing networks of preparedness and response. We observed that increasing communication frequency and diversifying the tiers of the interorganizational links enhanced the overall network's performance in the case of formal coordination. Network measures such as centrality, ...

ABSTRACT Information Systems (IS) is not a homogeneous discipline. Rather, it is comprised of various communities that are characterized by different perspectives and methods. With regard to the ongoing discussion about the profile of the discipline, this is a remarkable phenomenon. More specifically, it recommends analyzing the characteristic features of the various IS communities and explaining the diverse paths of development they took. Furthermore, it implies the question whether—and how—the current diversity could be overcome in order to foster a more focused competition as well as a more coherent presentation of research results on an international scale. This article contributes to such an investigation. It is focused on a comparison of the international English-speaking community predominantly (in particular in its early days) shaped by North-American IS researchers, which plays a leading role in the international scene, and the IS discipline in German-speaking countries (”Wirtschaftsinformatik” or WI, in Austria, Germany, and Switzerland), which constitutes the largest IS community outside North America that maintains its own approach. The focus of this article is mainly on describing the communities’ characteristics as the outcome of a social construction that is chiefly influenced by those individuals who participated in this construction. Against this background, eight scholars from North America and six scholars from German-speaking countries were interviewed at length. All were chosen as witnesses of and important contributors to the development of their discipline. As a result of this reconstruction, the article presents a rich picture of the communities’ history and characteristics as experienced and reported by the interviewees. The results obtained from this project indicate that neither of the two conceptions (IS or WI) can serve as an ideal model. Instead, a more intensive international exchange among the various research communities, including the Scandinavian and British scholars, should contribute to further develop the field into a more mature and satisfactory state.

The serum activity of beta-glucuronidase (beta-gluc) has been presumed to indicate the disease activity in rheumatoid arthritis (RA). In 10 patients with RA the serum beta-gluc was repeatedly determined after the initiation of a treatment with cyclosporin for one year. A significant increase of beta-gluc was found after 8, 12 and 16 weeks compared to the values before treatment, while the concentration of the soluble interleukin 2-receptor decreased. The data reveal, that beta-gluc is not a useful indicator of the disease activity during cyclosporin treatment.

We theorize on industry-level computerization by drawing data from on-going empirical study of the United States' residential real estate industry begun in 1997. Real estate serves us here as a ���living laboratory��� for studying information-intensive economic activity. In lieu of standard economic analyses, we advance computerization as the analytic framework for this study because it focuses attention to the take up and uses of information and communication technologies (ICT) in conjunction with related socioeconomic ...

National economies can be viewed as networks of interdependent relations among the firms, industries and sectors that make up the total economic system. Within this economic system. The communication industry plays a central role by providing message and media products and services, i.e. the linking and coordinating infrastructure.Some limited research has been conducted on the nature and importance of the communication industry in the total economic network of a nation. The study reported here, however, represents the first application of currently existing network analysis techniques to this problem on a large-scale basis. The data used for this study represent the interorganizational relationships among 365 West German firms, with a 1970-based stock value of $333,000 or more. Interorganizational linkages are a function of (1) direction of ownership, and (2) magnitude of ownership (percentage of stock owned weighted by the value of the owned firm).The data analysis reveals that there are a number of dominating industrial groups, including a communication industry. The inter-firm relationships of the communication industry have been mapped and measured. The analysis demonstrates that there is relatively little dominance in and widespread integration with other major economic clusters of the economy. These findings are considered as being preliminary since only publically reported data were available, i.e. privately controlled firms are not included in the analysis. A number of measures for connectedness and integrativeness are presented that suggest themselves in addition to the technique of network analysis per se as potential alternative measures. Media scholars as well as economists may want to utilize network analysis as a method to study various forms of economic concentration and ownership in national industries.
