Empirische Analysen und Empfehlungen für die Hochschulpraxis“ von Wilfried Schubarth, Karsten Speck und Andreas Seidel wird die Reihe „Potsdamer Beiträge zur Lehrevaluation“ unter neuem Titel und veränderter inhaltlicher Schwerpunktsetzung fortgeführt. Die Umbenennung in „Potsdamer Beiträge zur Hochschulforschung“ versteht sich als ein Schritt hin zu einer thematischen Öffnung der Reihe für die verschiedensten Felder der Hochschulforschung. Der vorliegende Band widmet sich einem der zentralen Reformziele von Bologna: der Frage des Praxis- und Berufsbezugs und dabei insbesondere den Praxisphasen im Studium. Mit der Bologna-Reform werden im bildungspolitischen Bereich sehr vielfältige strukturelle und inhaltliche Ziele verfolgt. Das Ziel dieses Bandes besteht deshalb darin, empirische Forschungen zu Praxisbezügen und Praxisphasen im Studium vorzustellen, diese in den Kontext aktueller Debatten um Studienqualität und Studienreform zu stellen sowie Folgerungen für die Gestaltung von Praxisphasen abzuleiten. Inhaltliche Schwerpunkte bilden das BMBF-Forschungsprojekt ProPrax und die Praxisphasen im Lehramtsstudium. Die Beiträge dieses Bandes gehen aus einem gleichnamigen Workshop hervor, der am 1. Oktober 2010 in Potsdam stattfand. N2 - The present conference volume „Beyond Bologna: Internship in studies – obligation or option? Empirical analysis and recommendations on the praxis of higher education“ by Wilfried Schubarth, Karsten Speck and Andreas Seidel is part of the serial “Potsdamer Beiträge zur Lehrevaluation” which is actually renamed as “Potsdamer Beiträge zur Hochschulforschung“. The new title supports modified focal points for research and provides opportunities for several fields of higher education research. The volume focuses on the practical relevance and the development of professional skills in academic studies as one of the central intentions of the Bologna Process. This Reform involves a variety of structural and content-related intentions in the field of educational policy. The aim of this conference volume is therefore to present empirical research with regard to practical relevance and internship in academic studies. It is linked to the current debate concerning quality of academic studies as well as the higher education reform in general and draws conclusions for the practical implementation of academic internships. The ProPrax research project, founded by the BMBF, and its first results as well as internships in teacher education are main issues of this volume. The contributions result from the correspondent Potsdam conference on October 1st 2010.

Predicting net livestock impacts on soil organic carbon stocks remains challenging, however, due to the dependence on animal loads and on soil and environmental parameters. The objective of this study was to better understand grazing effects on soil organic carbon in seasonal tropical dry forests of north-eastern Brazil (Caatinga) by quantifying carbon stocks of the upper soil profile (0–5 cm depth) and greater soil depths (>5 cm depth down to bedrock) along a gradient of grazing intensity while accounting for other influencing factors such as soil texture, vegetation, landscape topography, and water availability. We analysed soil organic carbon, soil clay content, altitude above sea level, soil depth to bedrock, distance to the nearest permanent water body, species diversity of perennial plants and aboveground biomass on 45 study plots located in the vicinity of the Itaparica Reservoir, Pernambuco, Brazil. Livestock (mainly goats and cattle) are unevenly distributed in the studied ecosystem, thus grazing intensity was accounted for based on the weight of livestock droppings per square metre and classified as no or light, intermediate, or heavy grazing. The mean soil organic carbon in the area was 16.86 ± 1.28 Mg ha−1 C with approximately one-quarter found in the upper 5 cm of the soil profile (4.14 ± 0.43 Mg ha−1 C) and the remainder (12.57 ± 0.97 Mg ha−1 C) in greater soil depths (>5 cm). Heavy grazing led to significantly lower soil organic carbon stocks in the upper 5 cm, whereas no effect on soil organic carbon of the soil overall or in greater soil depths was detectable. The soil’s clay content and the altitude proved to be the most relevant factors influencing overall soil organic carbon stocks and those in greater soil depths (>5 cm). Our findings suggest that grazing causes substantial release of carbon from Brazilian dry forest soils, which should be addressed through improved grazing management via a legally compulsory rotation system. This would ultimately contribute to the conservation of a unique forest system and associated ecosystem services.
