zur Praxis des Zeugenschutzgesetzes
No full textSoftcover, 372 S.: 22,00 €Softcover, 17x24Die Autorin beleuchtet die Praxis der Videovernehmung kindlicher Zeugen. Ausgangspunkt ihrer empirischen Untersuchung ist die Frage, ob die Gesetzesreform nicht nur gut gemeint ist, sondern auch praktisch umgesetzt werden kann. Hierbei knüpft sie an die Regelungen des 1998 geschaffenen Zeugenschutzgesetzes an, zu dessen Umsetzbarkeit im Sinne eines vom Gesetzgeber intendierten effektiven Opferschutzes, insbesondere der Vermeidung der sog. sekundären Viktimisierung (Traumatisierung), Experten aus Niedersachsen - Staatsanwaltschaft, Polizei und Gerichte - von ihren ersten Erfahrungen berichten. In fünf ausgewählten niedersächsischen Landgerichtsbezirken hat die Autorin zudem eine umfangreiche Aktenanalyse zum Einsatz von Videovernehmung durchgeführt und gelangt zu dem Ergebnis, dass die Videotechnologie im Strafverfahren so gut wie nicht eingesetzt wird. In konkreten Reformvorschlägen de lege ferenda werden auch die neueren Regelungen des Opferrechtsreformgesetzes von 2003 wertend in die Untersuchung einbezogen.The author examines the practice of video interrogation for children witnesses. Starting point for their empirical investigation is the question of whether the law reform is not only meant well, but can be implemented practically. Here the author builds on the regulations of the 1998 established law for witness protection, to its feasibility in terms of the intended effective protection of victims, particularly the avoidance of so-called secondary victimization (trauma), experts from the federal state of Lower Saxony - prosecutors, police and courts - report by their own experiencees. In five selected district courts of Lower Saxony, the author has also conducted an extensive document analysis on the use of video testimony, and concluded that the video technology in criminal proceedings is used rarely. In specific reform proposals „de lege ferenda“ also the recent regulations of the Law Reform Act of 2003 victims are included in the evaluative study
Estimates of biomass carbon stocks of the Baltic Sea ecosystem, version 2
No full textWe have estimated the standing stocks in carbon units per m² in the Baltic Sea ecosystem for 18 living and non-living groups relevant to carbon cycle and management activities in the Baltic Sea. We included three non-living apartments: POC, DOC and sediment carbon. The living groups comprise: phytoplankton, protozooplankton, bacteria, zooplankton, macrophythes, benthos, plaice, flounder, herring, sprat, cod, ringed seals, seals, grey seals and harbour porpoises. The estimates are based on ICES raw data and literature data and represent spatial and temporal averages. Data, data sources, assumptions and calculations are described in detail to ensure reproducibility

Eine Kohlenstoffperspektive auf höheren trophischen Ebenen - Wie tragen Tiere zum organischen Kohlenstoffkreislauf und -bestand in der Ostsee bei?
No full textThe world's oceans are an integral part of the Earth's climate system, contributing significantly to the mitigation of human-induced climate change through carbon cycling and storage. Marine organisms of all kinds, from the smallest virus to the largest whale, play various roles in both cycling and storage. Traditionally however, organisms higher up in the food web such as fish and marine mammals, have been given little to no consideration in this context, as their contribution was considered quantitatively negligible. Recent studies, conversely, show that these organisms can indeed make a significant contribution. However, despite increasing research, our understanding of how fish and marine mammals affect the ocean carbon cycle is still incomplete due to a lack of data, concepts and descriptions that encompass these organisms.
This incomplete understanding is particularly critical as populations of higher trophic levels are in steep decline worldwide. The contribution of these organisms may be changing as a result, while at the same time it has not even been fully understood, let alone quantified, especially in regional ecosystems. The Baltic Sea is one of the regional ecosystems where fish and marine mammals have not yet been accounted for in the carbon cycle and are simultaneously subject to significant population changes.
The Baltic Sea is a unique brackish ecosystem in Northeastern Europe. Exposed to high anthropogenic exploitation pressures and changing environmental conditions, the Baltic Sea has undergone several major transitions in the last decade. One consequence of these transitions includes the drastic reduction of the cod stock, one of the key higher trophic level species within the Baltic Sea. The sharp decline in the piscivorous cod population has implications for the food web, ecology of the Baltic Sea, and the livelihoods of many people who depend on this system. However, how the decline of cod affects carbon cycling and storage is unknown.
In this thesis, we advance the understanding of the contribution of higher trophic levels to organic carbon (OC) cycling and storage both globally and specifically within the Baltic Sea ecosystem. Although our investigations are mainly theoretical and conceptual, they fit into a picture that is increasingly emerging: Fish and other higher trophic levels can most likely make a non-negligible contribution to the marine carbon cycle and thus potentially to climate change mitigation. To account for the roles and contribution of these organisms in the future, scientific gaps need to be filled and a perspective shift in policy and management needs to be advanced

Constituent Information department of the University of Gothenburg (Informationsenheten vid Göteborgs universitet)
Course Master thesis in media and communications at the institution for journalism, media and communication at the University of Gothenburg
Term Spring 2013
Pages/ word count 77/ 32211 words
Objective To examine why researchers at the University of Gothenburg chose to blog in their role as a researcher
Method Exploratory analysis of qualitative, semi-structured interviews
Material Eleven interviews with blogging researchers from different fields at the University of Gothenburg, material gathered in spring 2012
Main results In the context of research communication blogs play an essential role for researchers for directly communicating with the public. A strong motivation for researchers to blog is that they can represent and create an image of themselves. Also the blog is
used in several ways as a tool in the researchers’ daily work.
Despite the fact that there are disadvantages with blogging, the researchers in the study find that it brings along far more advantages than disadvantages, which is why they keep blogging

A first estimate of the effect of offshore wind farms on sedimentary organic carbon stocks in the Southern North Sea
No full textOffshore wind farms (OWFs) can increase the transfer and stock of organic carbon (OC) in the surrounding sediments during their operational phase, while their construction and decommissioning release carbon. To answer the question whether sediments of OWFs trap more OC than they release, we estimate the net carbon effect over the entire life cycle (construction, operational and decommissioning phases) of OWFs in the Southern North Sea. Based on existing studies we compare the increased OC flux due to the colonization of organisms at the foundations of wind turbines and the OC loss due to sediment-disturbing activities during construction and decommissioning. Our results show that the areal intensity of carbon release in the disturbed areas is about 43.5 times higher than that of carbon trapping in the entire area of the OWFs. However, since the disturbed areas only account for about 0.50 ± 0.06% of the total area of the OWFs, in absolute terms about 4.6 ± 1.4 times more carbon is trapped in the sediment of the OWFs than is released. Due to limited data availability and the resulting need for extensive assumptions, our estimates only represent orders of magnitude. We therefore provide sensitivity estimates that define the limits of our calculations in terms of disturbance depth, remineralisation ratio, scour protection measures and heterogenous OC contents. In addition, we identify shortcomings of our extrapolation. Further research, especially more advanced impact assessments of construction and decommissioning processes must follow to improve the understanding of impacts of OWFs on sedimentary OC
Yang–Mills solutions and dyons on cylinders over coset spaces with Sasakian structure
No full textAbstractWe present solutions of the Yang–Mills equation on cylinders R×G/H over coset spaces of odd dimension 2m+1 with Sasakian structure. The gauge potential is assumed to be SU(m)-equivariant, parameterized by two real, scalar-valued functions. Yang–Mills theory with torsion in this setup reduces to the Newtonian mechanics of a point particle moving in R2 under the influence of an inverted potential. We analyze the critical points of this potential and present an analytic as well as several numerical finite-action solutions. Apart from the Yang–Mills solutions that constitute SU(m)-equivariant instanton configurations, we construct periodic sphaleron solutions on S1×G/H and dyon solutions on iR×G/H
