Männlichkeit verpflichtet. Die pädagogische Bearbeitung randständiger Männlichkeit im Zuge der Herstellung von Ausbildungsreife in der Berufsvorbereitung

Unter dem Vorzeichen wenig erfolgreicher formaler Bildungslaufbahnen finden sich dennoch nach wie vor problematische Orientierungen an stereotypen Männlichkeiten, die für Jugendliche die Anschlussmöglichkeiten an Bildungschancen vergrößern sollen. Dass auch ohne eine explizite Programmatik in pädagogischen Institutionen an der Veränderung von Männlichkeitskonstruktionen gearbeitet wird, um eine bessere habituelle Passung von Jugendlichen für die Erfordernisse des Arbeitsmarkts herzustellen, zeigt der Beitrag des Autors mit dem Titel Männlichkeit verpflichtet. Die pädagogische Bearbeitung randständiger Männlichkeit im institutionellen Alltag dualer Berufsvorbereitung. Der Artikel widmet sich mit der Berufsvorbereitung einem empirisch kaum ausgeleuchteten Feld. Vor dem Hintergrund einer in weiten Teilen geschlechtersegregierten Arbeitswelt und dem segmentierten Ausbildungssystem kommt Angeboten wie dem Berufsvorbereitungsjahr für Männlichkeitskonstruktionen eine immense Bedeutung zu. Wesentliches pädagogisches Moment solcher Angebote ist die Herstellung von Ausbildungsreife. Anhand eines methodenpluralen Forschungsprojektes mit Schülern im Berufsfeld Lagerlogistik legt der Autor das Augenmerk auf die Mitkonstruktionen eines männlichen Habitus durch die Ausbilder in den überbetrieblichen Klassen durch die Betonung männlicher Härte sowie der Ablehnung von als unmännlich markierter Schwäche, die sich vor allem an körperbezogenen Praktiken feststellen lässt. Als Fazit zieht der Autor, dass das pädagogische Arrangement der Berufsvorbereitung, das auf die Förderung von Ausbildungsreife zielt, sich in männlich dominierten Berufen demnach auch als eine „Schule von Männlichkeit“ verstehen lässt, welche insofern funktional ist, als sie auf die Herausbildung eines für die manuellen Tätigkeiten funktionalen Geschlechtshabitus abzielt.

Fluviatile und äolische Prozesse im Gebiet der unteren Elbe bei Neuhaus (Niedersachsen) seit dem Weichselspätglazial

The Late Glacial and Holocene landscape development in the vicinity of the River Elbe near Neuhaus, Lower Saxony, was studied during geological mapping of the area. The geological and geobotanical methods used in these investigations were chosen to cope with the difficulties which arise during research on Quaternary flood plains in low country. Paleochannel fill and areas of flood-plain sediments were drilled, the lithology examined, and the sediments dated on the basis of their pollen content. No evidence was found for the existence before the Middle Ages of paleo- channels the size of the present River Elbe. Before the first measures were made to regulate the Elbe River, it was an anastomosing river system with numerous small branches. The lower parts of the flood-plain profiles are predominantly sand and the upper parts silty-clayey loam. With the construction of effective levees over the last several centuries, the flow velocity of the Elbe has increased considerably during high water periods and instead of the deposition of meadow loam, sand was deposited as natural levees. The main belt of sand dunes on the east bank of the Elbe overlies Preboreal to Boreal lake mud and is, therefore, of Holocene age.

Gewebeansatz-Strukturen auf pyritisierten Steinkernen von Ammonoideen

3400 pyritized internal moulds of Upper Devonian, Triassic, Jurassic and Lower Cretaceous ammonoids show various soft tissue attachment structures. They are preserved as regularly distributed black patterns on the moulds. All structures can be interpreted as attachment areas of muscles, ligaments and intracameral membranes. Paired structures are developed along the umbilicus and on the flanks of the moulds, unpaired ones appear on the middle of their dorsal and ventral sides. Strong lateral muscles cause paired twin lines on the flanks of the phragmocone and of the body chamber. A ventral muscle is deduced from small rounded or crescent shaped spots in front of each septum on the ventral side. These spots are often connected, forming a band-like structure. Broad dark external bands on the ventral side of the phragmocone, ventral preseptal areas in the posterior part of the living chamber, small twin lines or oval shaped areas on the ventral side of the living chamber represent paired or unpaired attachment areas of the hyponome muscle. A middorsal muscle is documented by small roughened areas in front of each dorsal lobe. Dark spots along the umbilicus, often connected and thus forming a band-like structure (tracking band), are remains of a pair of small dorsolateral muscles at the posterior end of the soft body. Dark bands, lines and rows of small crescent shaped structures behind the tips of sutural lobes are due to spotlike fixation places of the posterior part of the mantle and their translocation before subsequent septal secretion. Devonian goniatites had a paired system of lateral and ventrolateral muscles preserved on the moulds as black or incised lines on the flanks of the living chamber and as dark preseptal areas, ventrally indented. These structures represent the attachment areas of paired lateral cephalic and paired ventral hyponome retractors. Fine black lines on the phragmocone situated parallel to the sutures (pseudosutures) represent a rhythmical secretion of camera! membranes during softbody translocation. Goniatites had a paired system of lateral and ventrolateral muscles, whilst Neoammonoids have a paired lateral and dorsolateral system, and, additionally, an unpaired system on the ventral and on the dorsal side. Mesoammonoids show only a paired lateral and an unpaired dorsal one. Fine black lines situated parallel to the saddles and behind the lobes of the suture line can be interpreted as structures left during softbody translocation and a temporary attachment of rhythmical secreted cameral membranes. Cameral membranes had supported the efficiency of the phragmocone. Only some of the observed structures are also present in recent Nautilus. Differences in the form and position of attachment sites between ammonoids and recent Nautilus indicate different soft body organizations between ammonoids and nautiloids. The attachment structures of goniatites especially of tornoceratids can be compared with those of Nautilus which indicates Richter - Gewebeansatz-Strukturen bei Ammonoideen 3 a comparable mode of life. Differences in the form and position of attachment structures between goniatites and ammonites may indicate an increasing differentiation of the muscular system in the phylogeny of this group. Different soft body organization may depend on shell morphology and on a different mode of life. On the modification or reduction of distinct muscle systems ammonoids can be assigned to different ecotypes. Based on shell morphology and the attachment areas of cephalic and hyponome retractor muscles two groups can be subdivided: - Depressed, evolute morphotypes with longidome body-chambers show only small ventral hyponome retractor muscles. Lateral cephalic retractors are not developed. These morphotypes are adapted to a demersal mode of life. Without strong cephalic retractor muscles no efficient jet propulsion can be produced. These groups represent vertical migrants with efficient phragmocone properties (multilobate sutures, cameral membranes, narrow septal spacing). - Compressed, involute moiphotypes with brevidome body-chambers show strong cephalic and hyponome retractor muscles and represent a group of active swimmers. These morphotypes were able to live at different depths, in the free water column or/and near the seafloor. They are not confined only to one habitat. Most of the examined genera and species belong to this group. Changes of the attachment structures in the course of ontogeny confirm that juveniles of Amaltheus and Quenstedtoceras lived as passive planche drifters in upper and intermediate parts of the free water column after hatching. At the end of the juvenile stage with a shell diameter of 0,3 - 0,5 cm cephalic retractor muscles developed. With the beginning of an active swimming mode of life (neanic stage) the subadult animals left the free water column and moved into shallow water habitats. Fuciniceras showed no marked changes in the attachment structures during ontogeny. This indicates that there occur no differences in the mode of life between juvenile and adult growth stages. Based on attachment structures and shell morphology of Devonian goniatites their relation to the systematic position permits statements about probable phylogenetic relationships between the Cheiloceratidae and Tornoceratidae. In some cases attachment structures of ammonites permit statements about phylogenetic relationships on family and genus level.

Bildungsforschung ohne kritische Theorie der Bildung? Ein Gutachten von Theodor W. Adorno zur Gründung eines (Max-Planck)„Instituts für Recht, Soziologie und Ökonomie der Bildung“ aus dem Jahre 1961

Der Autor kommentiert das Gutachten von Adorno zur Gründung des Max-Planck-Instituts für Bildungsforschung in Berlin. „Das Gutachten bietet eine willkommene Gelegenheit, sich angesichts des heute vorherrschenden mainstream von ‚Bildungsforschung‘ - und in PISA-Zeiten von ‚empirischer‘ zumal - noch einmal zu vergegenwärtigen, was der Anspruch von Bildungsforschung im Lichte der Kritischen Theorie der Bildung zu sein hätte. Es geht um das Problem der Verdinglichung, vor dem Adorno gewarnt hatte. Wenn Bildung (im Sinne des Wortes) festgestellt wird - als Bildungsgut, das erworben und besessen werden kann –, dann lassen sich definierte Bildungsprodukte messen und vergleichen, und wer dem aufsitzt, als was sie sich in Sachen ‚Bildung‘ ausgeben, ist ihrer Selbstideologisierung schon aufgesessen. Eben dies wollte Becker vermieden sehen.“ (DIPF/Orig.)

Geologie und Hydrogeologie im Raum Bad Pyrmont unter besonderer Berücksichtigung des Quellensystems

The hydrodynamics and hydrochemistry of salt and fresh water from solid rock aquifer systems in the Pyrmont area are described and interpreted on the basis of recent investigations including geoelectrics, isotope hydrology, soil air analysis. Theories on the source of the springs in this area are developed, which explain the different compositions of the springs and make it possible to protect them. Data from new and re-interpretated drill holes, borehole logs and outcrops suggest a revision of the geological structure of the Pyrmont dome. Bad Pyrmont is situated on a wide dome of Triassic rocks in the southern part of the Lower Saxony uplands. Inversion of the relief has caused the development of an erosional basin surrounded by prominent ridges. Deep faults developed at the crest of the dome as this part of the structure was subjected to the strongest tectonic stress. Subrosion of the Zechstein salts in the western part of the dome has caused the main salt bed to wedge out below the western part of the dome along a N-S striking structure; this structure is refered to as the „Salzhang“ (salt slope). West of the „Salzhang“, where subrosion has removed the salt bed that prevents gas rising from below, carbon dioxide of deep volcanic origin can now rise to the surface. Hydraulic cross sections illustrate the presence of extensive and deep-seated groundwater flow within the entire Pyrmont dome. While groundwater flow is directed vertically downwards in the ridges surrounding the dome, centripetal horizontal flow predominates the intermediate area. In the central part of the dome, groundwater rises to join the River Emmer, which is the main receiving water course in the central part of the eroded basin. The depth of the saltwater/freshwater interface is determinated by the weight of the superimposed freshwater body. Hydrochemical cross sections show the shape and position of the interface and document a certain degree of hydrochemical zonation of the gently mineralized fresh water. Genetic relationships between the two main water types and the hydrochemical zones of the freshwater body are discussed. The knowledge of the hydrogeological relationship in the Bad Pyrmont aquifer systems permits a spatially narrow coexistence of wells withdrawing groundwater for different purposes (medicinal, mineral, drinking and industrial water).

Late Devonian (Famennian) jaws: the icriodid multielement apparatus and its function

In this study the conodont multielement apparatus of Late Devonian (Famennian) Icriodus altematus is described which has been reconstructed from clustered group findings and separated elements. This apparatus is markedly different from classical ozarkodinid apparatuses and needs further consideration of its functional morphology. Since bedding plane assemblages of Icriodus altematus are yet unknown, a spatial reconstruction of this apparatus and a feeding mechanism are proposed which are based on the oropharyngal apparatus of recent lampreys. Though the extant representatives of petromyzontoids are not close phylogenetic relatives of extinct conodonts, there exist intriguing analogies concerning the morphology of the tooth types and the presumed spatial distribution within the oral cavity of both taxa.

Entwicklung der Faziesverteilung eines Riffkomplexes im Korallenoolith (Oberjura) des Osterwaldes (Niedersachsen)

The Hainholz quarry in the Osterwald hills of NW-Germany is the most impressive outcrop in the Lower Saxony Basin exposing Late Jurassic (Korallenoolith, Oxfordian) coral buildups. The Korallenoolith deposits in the quarry commence with a oolitic sequence about 20 m thick which is limited by a distinctive hardground at its top. This sequence is overlain by the so called “Obere Korallenbank”-Member about 13 m in thickness which is mainly build up by coral reef complexes. Throughout a lateral extend of about 400 m exposed in the quarry, the Obere Korallenbank Member shows numerous pillar-shaped reefal build ups which are flanked by a reefal debris limestone. The coral fauna of the in situ reefal bioconstructions comprises not less than 37 taxa most of which have been described from the Lower Saxony Basin for the first time. Probably, the pillar-shaped reefs formed a small positive relief of only a few dm against the debris deposits during deposition. The interreef debris limestones in the lower and middle part of the Obere Korallenbank Member show three intercalated biostromal coral layers. In the upper part of the member, the interreef facies is represented by a mikritic peloidal limestone rich in sponge remains and, unusual in such a depositional environment, ammonites (Dichotomo-sphinctes bifurcatoides, D. sp.). Additionaly, at the top of of the peloidal limestone a layer enriched in nerineids and other gastropods limits the reefal constructions of the Obere Korallenbank Member against the overlying “humeralis-Oolith” sequence. On the basis of the facies development of this depositional sequence the reef formation in relation to sealevel changes is discussed.

Paläobiogeographie des Korallenooliths (Mittleres Oxfordium - Unteres Kimmeridgium): Tethyale Faunen- und Florenelement auf höherer Paläobreite

An overview is given here on the palaeobiogeography of the Korallenoolith Formation (middle Oxfordian to early Kimmeridgian) in NW Germany (Lower Saxony Basin). Based on microfacies observations, abundant faunal and floral elements of the tropical tethyan realm are recognized in shallow-marine calcareous sediments of the Korallenoolith Formation. Foraminiferal fauna is both highly diverse and abundant and mostly of mediterranean character. Also, there is a small flora recorded, which includes heavily calcified red algae, aragonitic green algae, and cayeuxiid algae. They display restricted diversity when compared to those of shallow-marine tropical tethyan seas. Chaetetids and diceratids are locally abundant. Lithocodium aggregatum and Bacinella irregularis have been observed in Late Jurassic palaeolatitudes north of the Tethys for the first time. Corals are present in numerous genera and species. Their occurrence is restricted to a few horizons of the Korallenoolith Formation where they build patch reefs, coral biostroms and coral meadows. The overall character of the coral-thrombolite-reefs (florigemma-Bank Member) is very similar to those of the Tethys. The presence of these marine tethyan taxa assigned the position of the Lower Saxony Basin during middle Oxfordian to early Kimmeridgian palaeobiogeographically into the submediterranean province and reflects northward migration of tropical tethyan fauna and flora which reach in the Lower Saxony Basin their northern limit. These biota seem to be biogeo-graphically transitional between communities present in England and the Tethys.

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.
