Model-driven software adaptation:report on the workshop M-ADAPT at ECOOP 2007

This first edition of the workshop Model-driven Software Adaptation (M-ADAPT'07) took place in the Technische Universität Berlin with the International Conference ECOOP'07 in the beautiful and buzzing city of Berlin, on the 30th of July, 2007. The workshop was organized by Gordon Blair, Nelly Bencomo, and Robert France. Participants explored how to develop appropriate model-driven approaches to model, analyze, and validate the volatile properties of the behaviour of adaptive systems and its environments. This report gives an overview of the presentations as well as an account of the fruitful discussions that took place at M-ADAPT'07. © 2008 Springer-Verlag Berlin Heidelberg.

Sedimentology, geochemistry and ostracodes from Lake Ohrid

Ancient Lake Ohrid, located in the southern Balkan Peninsula in Macedonia and Albania is characterized by a high degree of endemism and it is considered to be the oldest lake in Europe. But its exact age (between one and ten million years) and also its origin are so far not known. To unravel these uncertainties an ICDP (International Continental Scientific Drilling Program) drilling project (Scientific Collaboration On Past Speciation Conditions in Ohrid (SCOPSCO)), started in April 2013. In addition to the investigations about the age and origin, other paleolimnological studies, e.g., the reconstruction of past climate and of past lake level changes, should be performed with the drilled cores. Used proxies in such paleolimnological studies are, e.g., ostracodes because they respond sensitively to environmental changes but an accurate knowledge of their preferences and tolerances to specific environmental conditions is necessary for this purpose. So far, this knowledge about the, mostly endemic, Ohrid ostracodes was limited. Thus, within the framework of this thesis, ostracodes and a multiplicity of environmental data were collected in Lake Ohrid and its adjacent waters during four field campaigns. In a total of 47 ostracode species could be detected in the entire study area and 32 of them were found alive in Lake Ohrid. Multivariate statistic identified that water depth, salinity, conductivity, pH, and dissolved oxygen were the main determining factors for ostracode distribution in the entire study area. In Lake Ohrid, the distribution was mainly controlled by water depth, water temperature, and pH. Some ostracodes were identified as strong indicator species for important environmental variables, e.g., water temperature and water depth. A distinctive feature of Lake Ohrid was the finding of the ostracode genus Amnicythere whose species normally inhabit oligo-(meso-)haline waters and this could point to a marine origin of the lake. So far, the specialized endemic ostracodes show the highest abundances and the greatest spatial distribution in Lake Ohrid but during the sampling eight widespread species were found for the first time in the lake. They inhabited mainly the northern part of the lake, where two cities are located and industry and agriculture play a major role, and they were limited to water depths above 50 m and this could be an evidence for an increasing anthropogenic pressure because widespread ostracode species often replace endemic species. To unravel the human impact on Lake Ohrid during the last decades short sediment cores were taken and the multi-proxy study indicated that the lake productivity between the early 1920s and the late 1980s was relatively low. Diatom assemblages indicate a rising productivity in the southern part of Lake Ohrid since the mid 1970s and geochemical proxies and ostracodes point to an increasing productivity since the late 1980s in the southern and in the northern part. A slight increase in the productivity continued until 2009. Noticeable is the fact that since the early 1990s, the increasing productivity and the increasing concentrations of heavy metals correspond to a decreasing number of ostracodes in the northern part of Lake Ohrid. Perhaps, this indicates that living conditions in this lake part became less favorable for the mostly endemic ostracode species. Furthermore, the sediment samples from the cores show relatively high concentrations of arsenic, iron, and nickel. Fluctuations in ostracode assemblages from three longer sediment cores, the longest spans approximately 136 ka, taken in Lake Ohrid, correspond to fluctuations in the productivity, in the carbonate content, of the lake level, and of climate changes. Between the marine isotope stage (MIS) 6 and MIS 2 the number of ostracode valves is very low or the valves were completely absent. This corresponds to a low lake productivity, a low carbonate content, and a low lake level. At the onset of the Holocene, the number of valves increased markedly and this correlates with an increased productivity and carbonate content and a warmer climate. But during the Little Ice Age (LIA), the number of valves dropped again and species which prefer warmer waters disappeared completely. This drop corresponds also to a low productivity. After the LIA, the number of species increased again but since 1895 AD a strong and abrupt decrease is visible. A reason for this could be an increase in the heavy metal concentrations.

@_I-T-A: Rechnereinsatz im klassischen Seminar

Am Ostasienzentrum der Technischen Universität Dresden wurden Fördermittel aus dem BMBF-Programm „Neue Medien in der Bildung“ dazu genutzt, E-Learning im Rahmen der klassischen Seminar-Situation zu erproben. Eingesetzt wurden Kurswebseiten, Nachrichtenforen und Selbstlernmodule. Gesucht wurde eine Antwort auf die Frage, ob sich die klassischen geisteswissenschaftlichen Lernziele damit besser erreichen lassen als ohne den Einsatz der technischen Hilfsmittel. Herausgekommen ist das ITA-Konzept. Es empfiehlt den Einsatz von Rechnern in geisteswissenschaftlichen Lehrveranstaltungen vor allem in drei Bereichen: Information, Training und Austausch.(DIPF/Orig.)

Fachliche Publikationskulturen und Open Access. Fächerübergreifende Entwicklungstendenzen und Spezifika der Erziehungswissenschaft und Bildungsforschung

Open Access zu öffentlich geförderten wissenschaftlichen Publikationen ist unter dem Vorzeichen der „Openness“ Teil einer zunehmend bedeutsamen globalen Entwicklung mit strukturellen Folgen für Wissenschaft, Forschung und Bildung. Dabei bedingen die jeweiligen fachkulturellen Ausgangslagen und ökonomischen Interessenskonstellationen sehr stark, in welcher Weise, mit welcher Reichweite und Akzeptanz sich das Open-Access-Paradigma konkret materialisiert. Die vorliegende Arbeit geht dieser Frage am Beispiel des inter- bzw. pluridisziplinären Feldes der Erziehungswissenschaft/Bildungsforschung nach. Zum einen werden die fachlichen und soziokulturellen Konstellationen des Publizierens im disziplinären Feld, die verlagswirtschaftlichen Marktkonstellationen sowie die informationsinfrastrukturellen Bedingungen des Fachgebietes analysiert und ein differenziertes Gesamtbild erstellt. Gestützt auf eine Online-Befragung der Fachcommunity Erziehungswissenschaft/Bildungsforschung werden weitergehende Erkenntnisse über vorhandene Open-Access-Erfahrungen im Fachgebiet und Hemmnisse bzw. Anforderungen an das neue Publikationsmodell aus der Sicht der Wissenschaftler/innen selbst – sowie explorativ aus Sicht der Studierenden und der Bildungspraxis - ermittelt. Wesentliche Faktoren bei der Betrachtung der Potenziale und Effekte von Open Access im Fachgebiet bilden die Faktoren akademischer Status und Funktion, Interdisziplinarität und fachliche Provenienz sowie das Verhältnis von Bildungspraxis und akademischem Sektor.
