Individual acceptance of the biogas innovation: A structural equation model
No full textThe rapid spread of biogas production in Germany has resulted in an increased public debate over this new business branch. Today the production of biogas is much more controversially debated than several years ago. At the same time it could be proven that even among farmers themselves the acceptance of biogas production in some regions is somewhat dampened due to accompanying "collateral damages". Therefore, the goal of this paper is to identify relevant influencing factors that determine the acceptance of the innovation "biogas" among farmers by applying a causal analysis. Initial results among the five investigated determinants show that not only an individual attitude toward biogas but also the farmers' personal innovativeness strongly and significantly influences an individual's acceptance of the innovation "biogas".

The Influence of Clusters on the Competitiveness of Hog Production: The Example of Northwestern Germany
No full textIn recent decades the northwestern part of Germany (Weser-Ems region) has come to focus on intensive pork production. This has led to public outrage about the disposal of biological waste, farmers’ complaints about the high cost of leasing land, soaring risks of animal diseases, and the decreasing popularity of intensive animal husbandry. However, despite these problems, due to a beneficial cluster structure, the region is a successful market participant. To shed some light on the relationship between network relationships in clusters and competitiveness, an empirical survey was undertaken to compare this pork-intensive region with non–pork-intensive regions. Bi- and multivariate analyses reveal a better access to knowledge and information on the part of farmers in the Weser-Ems region as well as a higher regional competitiveness. As a result, the cluster region characterized by intensive hog production is economically more successfu
Determinants of the Use of Information: An Empirical Study of German Pig Farmers
No full textDue to growing expectations for quality and safety of food products and an increasing demand for more transparent food supply chains, pork production faces new challenges. In the course of this development, chain-wide communication has gained importance in agribusiness. Nonetheless, existing approaches focus primarily on information supply, whereas the use of information for managerial decision-making has only rarely been highlighted. This research gap is addressed in this paper on the basis of a large-scale empirical study of animal health management on German pig farms. By applying factor and multinomial logistic regression analyses, this study identifies determinants of the use of information as well as ways to improve information use on farms. It shows that factors like intrinsic motivation and farmer's competence have a significant influence on information use.INTERREG IVA Project SafeGuar

Administrative cooperation and disease control in cross-border pork production
No full textIn recent years, the continuous structural change in the value chain of modern food production has been characterised by an increasing international division of labour among manufacturing companies. A regional specialisation of primary agricultural production is especially apparent in meat production. Thus, the German-Dutch border area has developed into a region of unprecedented intensive pork production. While The Netherlands specialises in piglet production, the production of fattened pigs continues to grow in northwest Germany. As a result of this increasing transnational value chain development, German imports of Dutch piglets have risen continuously since 2000. However, this structural interweaving of pork production between The Netherlands and Germany has resulted in many new challenges for the cooperation between the various participants and in particular for the administrative authorities in the field of food and feed safety as well as efficient animal disease control. The motivation for this exploratory study stems from the lack of scientific work on this topic to date. The aim of this research is to illustrate the relevance of functioning cross-border cooperation in the food sector, using commodity flow structures and disease spread analysis. Results indicate that cross-border cooperation between authorities during a CSF epidemic can reduce the risk of recurrence and the duration by 50%. (C) 2012 Elsevier Ltd.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
