Musikalisches Involviertsein als Modell kultureller Teilhabe und Teilnahme

In recent years, the concept of cultural participation has become very popular both in the scientific context as well as in the political discourse. Despite that, a sound definition of the construct allowing for solid empirical data collection and analysis is still missing. While this is a major obstacle for researchers, society and political decision makers ask for evidence-based knowledge concerning the effects and benefits of cultural education and assistant measures. Based on Amartya Sen’s “Capability Approach” and on a broad conception of culture, the authors try to fill this gap and propose a theoretical model of “musical involvement” to describe cultural participation in music.

Bryozoan borings in shells of Costa Rican miocene oysters

Borings of bryozoan colonies are rare fossils and hitherto unknown from Central America. Four different types of zoaria, belonging to Spathipora sp., Terebripora sp. A, Terebripora cf. falunica and Iramena sp., were recognized. They are developed on shells of Miocene oysters (Saccostrea sp. and Ostrea sp.) from shell - beds of the Venado-Formation (Northern Limon - San Carlos Basin, Costa Rica). The period of colonization and growth by bryozoans and/or a few other benthic invertebrates was probably a short - term event, followed by suffocation from accumlating sediment.

Age an origin of the "Mexican Onyx" at San Antonio Texcala (Puebla, Mexico)

A great variety of color banded CaC03 is known as „Mexican Onyx“, and is extensively used for ornamental purposes. Within the San Antonio Texcala mining district an area of about 24.000 m2 is covered by a thick travertine crust with a calculated volume of at least 2,8 x 1061. It originates from warm waters that emerge on young fissures and faults. It seems to be likely that the travertine formation is related to the hydrothermal activity of the Transmexican Volcanic Belt and to the seismicity of this zone. The deposit is built up by different travertine varieties. The main lithotypes are: (1) dense crystalline laminated travertine; (2) ray crystal travertine; (3) shrub layer travertine; (4) irregular porous travertine; (5) travertine breccia. Textural variation seems to be related to water temperature/distance from the emergence point, rapid or slow degassing of CO, and bacterial influence. At the moment, a light green banded variety (native sulfur impurities) is mined. It is the facture fill of a morphological prominent fissure-ridge travertine. U/Th data indicate, that the travertine has been deposited since at least 52 + 5 ka.

Anlage-Umwelt-Diskurs. Historie, Systematik und erziehungswissenschaftliche Relevanz

Sind Menschen das Produkt ihrer Gene oder ihres Umfeldes? Ist Intelligenz erblich? Kommen Mädchen und Jungen bereits mit vorgeprägten Gehirnstrukturen zur Welt? Kaum eine wissenschaftlich geführte Debatte ist so oft aufgegriffen, heftig diskutiert und als gelöst oder auch prinzipiell unlösbar deklariert worden wie die Frage, ob die Fähigkeiten eines Menschen stärker (oder gar ausschließlich) durch die Anlagen (Gene) oder durch Umwelteinflüsse (Milieu, Erziehung) bestimmt werden. Ziel der Untersuchung ist [...] eine Rekonstruktion des internationalen und interdisziplinären Diskurses über Anlage und Umwelt von seinen Anfängen in der Antike bis zur Gegenwart. Als aktuelle Positionen werden die Verhaltensgenetik (Zwillingsforschung), Soziobiologie/Evolutionspsychologie sowie kritische Ansätze eines konstruktivistischen Interaktionismus vorgestellt. Zudem werden anhand von Beispielen aus den Bereichen "Intelligenz" (Jensen-Debatte und Burt-Skandal der 1970er Jahre) und "Geschlecht" (Mead-Freeman-Kontroverse in den 80er Jahren und der Fall David Reimer zur Jahrtausendwende) vier heiße Phasen des Diskurses nachgezeichnet und hinsichtlich der Intentionen und Strategien der beteiligten Akteure hinterfragt. Abschließend wird die Bedeutung aktueller Positionen für die Erziehungswissenschaft diskutiert und nach Konsequenzen für die pädagogische Forschung, Theoriebildung und künftige Rezeptionsperspektiven biologischen Wissens gefragt.

Teeth of a small durophagous crocodile from the Late Jurassic (Kimmeridgian) of North Germany

An outcrop of Late Jurassic (Kimmeridgian) age in Lower Saxony (NW Germany) has yielded small teeth probably of crocodilian origin. The dental morphology is still unknown among crocodiles and indicates a durophagous habit. The teeth are provisionally referred to as Metasuchia fam., gen. et sp. indet.

Hydrothermale Dolomitisierung im Kauffunger Kalkstein (Paläozoikum - W-Sudeten, Polen

Within the Kauffung Limestone dolomite bodies related to volcanic contacts occure and are interpreted as a post-Variscan, hydrothermal volcanogenic formation. Two genetic dolomite types are discernible: a pervasive replacement saddle dolomite and a cavity filling saddle dolomite cement. Micro texture and oxygen isotopy of both dolomite types refer to heightened temperatures of formation. The ocurrence of the dolomite in contact to cross-cutting rhyolithic dikes points to a close petrogenetic relation. Dolomite bodies and rhyolithic injections in contrast to the rock wall are characterized by a distinctive cavernous texture, so that a prekinematic genesis is excluded. The formation of replacement saddle dolomite and saddle dolomite cement altogether are considered as a concomitant phenomenon of the Permo-Carboniferous volcanism widespread in the Bober-Katzbach Mountains.

Der Kauffunger Kalkstein (Bober-Katzbach Gebirge, Polen): Petrographie, Fossilinventar, Stratigraphie

In the Western Sudetes (Mts.) in SW Poland carbonate rocks occur which are well known in the older German literature as ’’Kauffung Limestone” or ’’Wojcieszow Limestone” in recent publications, respectively. They are intercalated in sedimentary (shales) and volcanic (greenstone) successions and are, presumed - due to the lack of index fossils - to be Cambrian in age. These deposits occur in a variety of isolated massifs in the Bober-Katzbach Mts. where they have been mined in many quarries in the past. In a single location (Polom quarry near Wojcieszow) they are exploited up until today. The predominantly calcitic rocks display a wide variety of different lithologies and are, consequently, subdivided into the following lithological units which differ in textural characteristics, mineral constituents, and different grades of diagenetic and metamorphic alteration: 1. Calcite Marble: massive, calcitic, chiefly metamorphic recrystallized. 2. Zebra Limestone: dolomitic-calcitic, certain content of metasomatic silica, fine bedding as a result of microbial calcite precipitation or of diagenetic to metamorphic separation of carbonate and silica constituents. 3. Massive matrix Dolomite: compact, of diagenetic to metamorphic origin. 4. Dolomite Marble: metamorphic. 5. Hydrothermal Dolomite: hydrothermal alteration of limestone, postdating the tectonic deformation. The recent appearance of ’’Kauffung Limestone” is mainly a result of regional metamorphosis at low temperature up to about 300°C and locally high pressure. The typical textural features are stress induced, mostly protomylonitic calcite recrystallisation and generally slowly or not infected dolomite crystals. The different reactions of the two carbonate phases are attributed to their mineral properties. Rhyolitic and dacitic dykes penetrating the carbonate rocks are interpreted as a result of post- orogenic, probably Carboniferous or Permian volcanism. Microprobe investigation on the carbonates revealed a stochiometric composition of dolomite and calcite. The stable isotope content (8 c 0,8* ^C) reflects increased crystallisation temperature of the carbonate minerals (8 O von -7,75 bis -15,78). A variety of fossil remains have been extracted from bulk samples, consisting of sponge needles, floral components, foramini- fera, and vertebrate remains the latter two of which indicate a depositional age younger than Ordovician. Due to the stratigraphic re-attribution of the Kauffung Limestone, the hypothesis of a Cambrian/Ordovician rifting in the Western Sudetes should be abandoned.

Beurteilung der geomechanischen Stabilität und Integrität von Endlagerbergwerken im Salzgebirge auf der Grundlage geologischer und ingenieurgeologischer Untersuchungen

Any safety assessment of a permanent repository for radioactive waste has to include an analysis of the geomechanical stability of the repository and integrity of the geological barrier. Such an analysis is based on geological and engineering geological studies of the site, on laboratory and in-situ experiments, and on numerical calculations. Central part of the safety analysis is the geomechanical modelling of the host rock. The model should simulate as closely as possible the conditions at the site and the behaviour of the rock (e.g., geology, repository geometry, initial rock stress, and constitutive models). On the basis of the geomechanical model numerical calculations are carried out using the finite-element method and an appropriate discretization of the repository and the host rock. The assessment of the repository stability and the barrier integrity is based on calculated stress and deformation and on the behaviour of the host rock measured and observed in situ. An example of the geomechanical analysis of the stability and integrity of the Bartensieben mine, a former salt mine, is presented. This mine is actually used as a repository for low level radioactive waste. The example includes all necessary steps of geological, engineering geological, and geotechnical investigations.

Die Erziehungswissenschaft im Vereinigten Königreich: Die erziehungswissenschaftliche Forschungslandschaft im Spiegel der Forschungsevaluation

Der Autor widmet sich der erziehungswissenschaftlichen „Forschungslandschaft im Spiegel der Forschungsevaluation“ im Vereinigten Königreich und stellt Ergebnisse der Research Excellence Framework (REF) vor, eine Forschungsevaluation, die zwischen 2013 und 2014 an allen hochschulischen Einrichtungen im Vereinigten Königreich stattfand. Ein interessantes Ergebnis der referierten REF-Daten ist, dass es keine vollständige Gleichberechtigung zwischen Wissenschaftlerinnen und Wissenschaftlern in Bezug auf für die Karriere relevante Forschungsmerkmale gibt.
