Impact of biogas production on the regional land lease market - Empirical study of five rural districts in Lower Saxony with high density of biogas plants
No full textImpact of biogas production on the regional land lease market - Empirical study of five rural districts in Lower Saxony with high density of biogas plants - The study analyzes the effects of biogas production on the regional land lease market in five rural districts of Lower Saxony. The regions chosen for the study, which are characterized by a high density of biogas plants and to some extent also of animal husbandry, were the counties Celle, Soltau-Fallingbostel, Emsland, Rotenburg (Wumme) and Oldenburg. In the theoretical part in which the relationship between the biogas production and the price for leasing farmland was determined, it could be shown by use of functional income analysis that under the average market conditions in the 2006 to 2009 period an exemplary farm in the Soltau-Fallingbostel region was able to enjoy internal advantages and could realize a higher maximum willingness to pay for arable land by the addition of energy maize in its crop rotation. The empirical results from the five regions also underscore the high importance individual farmers place on biogas production in regard to the leasing market. The surveyed biogas farmers on average consider themselves as being fitter for the future, more successful and due to the higher maximum willingness to pay for arable land more competitive on regional land lease markets than other farmers. However, the survey also clearly pointed out that even in regions with a relatively high density of biogas plants as well as a stagnating or even decreasing animal population, the biogas production currently exerts an increasingly strong effect on the land lease market, which leads to increasing rents for arable land and crowding out on the land market. Therefore, the competitiveness of the regional food production can decline through the promotion of biogas production, since the rising costs of land use can increase the cost of individual farm growth as well as the production costs of food and forage
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".

Evaluierung IT-gestützter Betriebsmodelle zur Abbildung einzelbetrieblicher Anpassungsstrategien an den Klimawandel auf typischen Ackerbaubetrieben
No full textIn Zukunft müssen sich landwirtschaftliche Ackerbaubetriebe an die Folgen des Klimawandels operativ und strategisch anpassen, um langfristig wettbewerbsfähig zu bleiben. Mit Hilfe von einzelbetrieblichen Simulationsund Op- timierungsmodellen lassen sich schon im Vorfeld Auswirkungen der Umweltver- änderungen quantifizieren sowie sinnvolle einzelbetriebliche Anpassungsmaßnahmen ableiten. Dazu werden in diesem Beitrag die drei Betriebsmodelle FarmBoss, MODAM und TIPI-CAL vorgestellt, die für die ökonomischen Analysen auf typischen Ackerbaubetrieben grundsätzlich Verwendung finden können. Es zeigt sich hierbei, dass für die Abbildung einzelbetrieblicher Anpassungsstrategien auch auf Expertenwissen (z.B. Berater, Landwirte) zurückgegriffen werden sollte
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
