Rechtsbeziehungen von Open Source Entwicklungsgemeinschaften

Als Triumph der Open Source Bewegung wurde im vergangenen Jahr das Urteil des Landgerichts München I1 gefeiert, das als weltweit erste Gerichtsentscheidung der General Public Licence (GPL) rechtliche Verbindlichkeit zusprach und einem Sofwarehersteller die kommerzielle Verwertung eines unter der GPL stehenden Computerprogramms ohne Quellcodeweitergabe untersagte

Intrinsic and extrinsic diffusion of indium in germanium

Diffusion experiments with indium (In) in germanium (Ge) were performed in the temperature range between 550 and 900°C. Intrinsic and extrinsic doping levels were achieved by utilizing various implantation doses. Indium concentration profiles were recorded by means of secondary ion mass spectrometry and spreading resistance profiling. The observed concentration independent diffusion profiles are accurately described based on the vacancy mechanism with a singly negatively charged mobile In-vacancy complex. In accord with the experiment, the diffusion model predicts an effective In diffusion coefficient under extrinsic conditions that is a factor of 2 higher than under intrinsic conditions. The temperature dependence of intrinsic In diffusion yields an activation enthalpy of 3.51 eV and confirms earlier results of Dorner et al. [Z. Metallk. 73, 325 (1982)]. The value clearly exceeds the activation enthalpy of Ge self- diffusion and indicates that the attractive interaction between In and a vacancy does not extend to third nearest neighbor sites which confirms recent theoretical calculations. At low temperatures and high doping levels, the In profiles show an extended tail that could reflect an enhanced diffusion at the beginning of the annealing

The demandingness of Nozick’s ‘Lockean’ proviso

Interpreters of Robert Nozick’s political philosophy fall into two broad groups concerning his application of the ‘Lockean proviso’. Some read his argument in an undemanding way: individual instances of ownership which make people worse off than they would have been in a world without any ownership are unjust. Others read the argument in a demanding way: individual instances of ownership which make people worse off than they would have been in a world without that particular ownership are unjust. While I argue that the former reading is correct as an interpretive matter, I suggest that this reading is nonetheless highly demanding. In particular, I argue that it is demanding when it is expanded to include the protection of nonhuman animals; if such beings are right bearers, as more and more academics are beginning to suggest, then there is no nonarbitrary reason to exclude them from the protection of the proviso

Helicobacter pylori and Gastric Mucosa-associated Lymphoid Tissue (MALT) Lymphoma: Updated Review of Clinical Outcomes and the Molecular Pathogenesis

In most H. pylori-positive patients, gastric low-grade mucosa-associated lymphoid tissue (MALT) lymphomas regress both endoscopically and histopathologically after H. pylori eradication, but no factors that can be predictive of the response to the eradication have been definitively identified, and there is little information on how to determine the optimal observation period before additional treatment can be started. Here, clinical studies dealing with the diagnosis and treatment of gastric MALT lymphomas and H. pylori published during the last 5 years were systematically reviewed, and studies identifying the molecular approaches involved in the pathogenesis were summarized. Most of the clinical studies indicate a favorable effect of H. pylori eradication on the clinical outcome of gastric MALT lymphomas. Some studies suggest the necessity of additional treatment in nonresponders to H. pylori eradication, while others suggest the adoption of a watch-and-wait strategy. The molecular characteristics of MALT lymphomas could play an important role in prognostic prediction and the selection of further therapeutic intervention after the eradication. This updated review of gastric MALT lymphomas illustrates the potential efficacy of H. pylori eradication in tumor remission, but further molecular characterization is necessary to establish the most suitable therapeutic strategy for patients who do not respond to eradication

Robert Nozick on nonhuman animals : rights, value and the meaning of life

In his chapter, Josh Milburn argues that Robert Nozick considers nonhuman animals in his philosophical writings, but that these discussions are downplayed in animal ethics and Nozick scholarship. This is regrettable, Milburn proposes, as Nozick is far more sympathetic to animal rights than many other libertarians. Milburn thus offers an analysis of Nozick’s animal ethics. Nozick’s arguments concerning vegetarianism and speciesism are considered, and Milburn argues that tensions in Nozick’s political philosophy potentially open the door to animal rights. Whatever their place in his political philosophy, Milburn contends, nonhuman animals find a comfortable home in Nozick’s axiology and ethics, with their value and the significance of our duties towards them affirmed. Milburn concludes that animal ethicists could learn from Nozick’s distinctive arguments and approaches and find an unexpected ally
