Flächeninanspruchnahme 2020 und das 30-ha-Ziel: Regionale Verteilungsschlüssel und Anpassungserfordernisse
Get PDF


The reduction of land development and the attainment of the national 30-ha-sustainability-target require all states, regions and municipalities in Germany to adjust. Up to now, however, regional targets for local jurisdictions have not been achieved. This paper presents a top-down mechanism by which a national target is subdivided according to the population and total area shares of each administrative unit. Distributional implications of this rule are analyzed on the level of states and regions. For this purpose, the derived sub-quantities are compared with the past and future land development rates. The future development of land consumption is estimated by the Panta Rhei Regio model, which projects growth rates of settlement and traffic areas until 2020. The results show that although land development will decline significantly in the next years, it will still clearly remain above the 30-ha-target level. As the simulation is modeled on county level the results also indicate the need to specify detailed quantity standards at regional level. A definition of subdivided targets for states, regions and municipalities offers the opportunity to improve the ongoing German debate on open space preservation and to initiate greater efforts on the way to a more efficient use of natural resource land.

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
Lebensraumverbund und Siedlungsentwicklung in Deutschland
No full textDie Flächeninanspruchnahme durch Bebauung ist nach den Wirkungen von Land-, Forst- und Wasserwirtschaft eine der wesentlichen Gefährdungsursachen für die Biologische Vielfalt. Neben dem generell hohen Flächenverbrauch ist die Lage wachsender Siedlungsflächen ein kritischer und für den Erhalt von Verbundbeziehungen wichtiger Aspekt. Häufig knüpfen neu bebaute Flächen an bestehende Siedlungs- und Verkehrsflächen an, verbinden diese oder erzeugen Siedlungsbänder. Infolge von Flächeninanspruchnahmen wurden in Deutschland in der Vergangenheit wichtige Lebensraumverbindungen im Lebensraumverbund durch Siedlungserweiterungen irreversibel unterbrochen. Im vorliegenden Band werden die Methoden und Ergebnisse einer bundesweiten Analyse zu möglichen Zerschneidungen wichtiger Zusammenhänge in den Lebensraumnetzen durch Siedlungsraumentwicklung beschrieben und dargestellt. Besonderes Augenmerk liegt auf "Engstellen" oder räumlichen "Flaschenhälsen" im überregionalen Lebensraumverbund. Die Ergebnisse sind als GIS-Shapes und Karten so aufbereitet, dass sie für bundesrelevante Planungen genutzt und mit weiteren naturschutz- und infrastrukturrelevanten Daten kombiniert werden können. Mit der näheren Betrachtung ausgewählter Engstellen-Gebiete, die auf Basis der bundesweiten Analyse gemeinsam mit dem BfN ausgewählt wurden, werden die Ergebnisse veranschaulicht. Der Band schließt mit Planungsempfehlungen, in denen erläutert wird, wie die Ergebnisse in der Landschafts- und Raumplanung (z. B. im Rahmen der Regionalplanung) in den Ländern, Regionen und Kommunen Verwendung finden können
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
