Uguaglianza e differenza di genere nella riforma del diritto di famiglia: una lettura luhmanniana

La igualdad ante la ley es uno de los derechos fundamentales de las Constituciones modernas. Sin embargo, hay algo más. De hecho podría decirse que los modernos sistemas jurídicos se han ido formando alrededor de la idea de igualdad. El valor de la igualdad parece expresar una manera común de entender las relaciones humanas, especialmente en el caso de la igualdad de género, expresamente mencionado por el artículo de las Constituciones democráticas modernas que se refiere al principio de igualdad ante la ley. El presente estudio trata esa forma específica de igualdad que se caracteriza por la paradoja de querer tratar como igual lo que es diferente, o sea, de hacer distinciones sin discriminar. Con este fin nos referimos al enfoque jurídico y al enfoque político del tema como se encuentran en la reforma del derecho de familia. No es un problema de una específica legislación nacional, sino más bien una versión específica de un problema de nivel general. Se trata de la imposibilidad de construir como indistinguible lo que es diferente. El intento político de reformar el derecho de familia para implementar el principio constitucional de igualdad no consigue resolver el problema. Éste vuelve a aparecer por la imposibilidad que el derecho funcione sin crear diferencias. Al mismo tiempo, surgen problemas nuevos relacionado con formas nuevas de organizar la vida familiar.

Ensayo ganador del VII premio Enrique Ruano Casanova: La presencia del crucifijo en las aulas. Jurisprudencia nacional y europea

Cuando se aprueba la Constitución Española en 1978, España se convierte en un Estado aconfesional, reconociendo por primera vez un verdadero derecho de libertad religiosa de todos los individuos. Precisamente, el ejercicio de esta libertad en una situación de igualdad ha originado diversas polémicas desde que se instauró la democracia. Una de las controversias que más repercusión ha tenido en los últimos años viene determinada por la presencia de los crucifijos u otros símbolos en las aulas de algunos colegios públicos, cuestión que ha sido abordada por los tribunales españoles, así como por el Tribunal Europeo de Derechos Humanos.

Maximilian’s Journeys through Spain and Brazil: The Long Way to the Mexican Empire

In May of 1864, Maximilian of Austria reached the Mexican coast, being this journey his last, ending three years later with his execution. Much has been written about the reasons that prompted his acceptance of the crown of Mexico, a country so distant in every sense of his cultural environment. However, years ago Maximilian had traveled to Spain and Brazil (to Spain twice) and these experiences, although not determinant, greatly influenced the decision of the Archduke, who saw the chance to realize a dream he had conceived on his trip to Spain and that was consolidated during his stay in Brazil, as we can extract from his travel memoirs.

La imagen de España en la novela de viaje "Cabo de Gata" de Eugen Ruge

Este artículo presenta un análisis de la imagen de España trazada en la novela Cabo de Gata (2013). Con ello se toma en consideración un género que, hasta ahora, ha recibido poca atención en la investigación de la imagen de España en la literatura de viajes alemana. El foco del análisis lo constituyen tanto el motivo del viaje como la percepción y representación de lo ajeno español. Por último, el análisis narratológico de los diversos aspectos seleccionados de la técnica narrativa nos servirá para delimitar la repercusión imagológica de la novela.

Gestengestützte Schema- und Datenexploration

Der Zugang zu Datenbanken über die universelle Abfragesprache SQL stellt für Nicht-Spezialisten eine große Herausforderung dar. Als eine benutzerfreundliche Alternative wurden daher seit den 1970er-Jahren unterschiedliche visuelle Abfragesprachen (Visual Query Languages, kurz VQLs) für klassische PCs erforscht. Ziel der vorliegenden Arbeit ist es, eine generische VQL zu entwickeln und zu erproben, die eine gestenbasierte Exploration von Datenbanken auf Schema- und Instanzdatenebene für mobile Endgeräte, insbesondere Tablets, ermöglicht. Dafür werden verschiedene Darstellungsformen, Abfragestrategien und visuelle Hints für Fremdschlüsselbeziehungen untersucht, die den Benutzer bei der Navigation durch die Daten unterstützen. Im Rahmen einer Anforderungsanalyse erwies sich die Visualisierung der Daten und Beziehungen mittels einer platzsparenden geschachtelten NF2-Darstellung als besonders vorteilhaft. Zur Steuerung der Datenbankexploration wird eine geeignete Gestensprache, bestehend aus Stroke-, Multitouch- und Mid-Air-Gesten, vorgestellt. Das Gesamtkonzept aus Darstellung und Gestensteuerung wurde anhand des im Rahmen dieser Arbeit entwickelten GBXT-Prototyps auf seine reale Umsetzbarkeit hin, als plattformunabhängige Single-Page-Application für verschiedene mobile Endgeräte mittels JavaScript und HTML5/CSS3 untersucht.

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).

Die Zunahme intraanueller Zuwachsstreifen bei Muscheln im Laufe der Erdgeschichte

Die Deutung der stärkeren Wachstumsunterbrechungen auf den Schalen von Muscheln als "Jahresringe" wird weiter unterbaut. Bei langlebigen Arten wird daraus ein Rhythmus nachgewiesen, der an den 11-jährigen Sonnenfleckenrhythmus erinnert. Die kleineren intraannuellen Wachstumsstörungen ("Monatsringe?") werden in ihrer durchschnittlichen jährlichen Häufigkeit vom Silur bis zur Gegenwart verfolgt. Es wird eine allmähliche Zunahme im Verlauf der Erdgeschichte festgestellt. Dabei ergeben sich kleinere Sprünge zwischen Karbon und Perm sowie zwischen Trias und Jura. Ein größerer Sprung ist zwischen Jura und Kreide erkennbar. Im Palaeozän gleichen die Zahlen noch sehr denen der Kreide, während vom Eozän ab wieder eine dann gleichbleibende Zunahme sichtbar ist. Die intraannuellen Zuwachsunterbrechungen ("Monatsringe") dürften in der Mehrzahl nicht durch Milieueinflüsse entstanden sein. Zu ihren Ursachen könnten vielleicht Beziehungen zur Kurve der Beschleunigung des erdgeschichtlichen Ablaufes oder jener der Erdexpansion hinführen. Auch die "Monatsringe" lassen unter der Lupe noch kleinere Wachstumsunterbrechungen erkennen, bei denen am ehesten noch örtliche Milieubedingungen mitgewirkt haben könnten.

Riffe und fazielle Entwicklung der florigemma-Bank (Korallenoolith, Oxfordium) im Süntel und östlichen Wesergebirge (NW-Deutschland

During the Sedimentation of the platform carbonate deposits of the Korallenoolith Formation (middle Oxfordian to early Kimmeridgian) small buildups ofcorals formed in the Lower Saxony Basin. These bioconstructions are restricted to particular horizons (Untere Korallenbank,ßorigenuna-Bank Member etc.) and represent patch reefs and biostromes. In this study, the development of facies, fossil assemblages, spatial distribution of fossils, and reefs of the ßorigenuna-Bank Member (upper Middle Oxfordian) in the Süntel Mts and the eastern Wesergebirge Mts is described; the formation of reefs is discussed in detail. Twelve facies types are described and interpreted. They vary between high-energy deposits as well winnowed oolites and quiet-water lagoonal mudstones. Owing to the significance of biota, micro- and macrofossils are systematically described. The reefs are preserved in growth position, are characterized by numerous corresponding features and belong to a certain reef type. According to their size, shape and framework, they represent patch reefs, coral knobs (sensu James, 1983), coral thrombolite reefs (sensu Leinfelder et al., 1994) or “Klein- and Mitteldickichte” (sensu Laternser, 2001). Their growth fabric corresponds to the superstratal (dense) pillarstone (sensu Insalaco, 1998). As the top of the ßorigenuna-Bank displays an erosional unconformity (so-called Hauptdiskontinuität), the top of the reefs are erosionally capped. Their maximum height amounts to at least the maximum thickness of the ßorigenuna-Bank which does not exceed 4 metres. The diversity of coral fauna of the reefs is relatively low; a total of 13 species is recorded. The coral community is over- whelmingly dominated by the thin-branched ramose Thamnasteria dendroidea (Lamouroux) that forms aggregations of colonies (77?. dendroidea thickets). Leafy to platy Fungiastrea arachnoides (Parkinson) and Thamnasteria concinna (Goldfuss) occur subordinately, other species are only of minor importance. In a few cases, the reef-core consisting of Th. dendroidea thickets is laterally encrusted by platy F. arachnoides and Th. concinna colonies, and microbial carbonates. This zonation reflects probably a succession of different reef builders as a result of changing environmental conditions (allogenic succession). Moreover, some reefs are overlain by a biostrome made of large Solenopora jurassica nodules passing laterally in a nerinean bed. Mikrobial carbonates promoted reef growth and favoured the preservation of reef organismn in their growth position or in situ. They exhibit a platy, dendroid, or reticulate growth form or occur as downward-facing hemispheroids. According to their microstructure, they consist of a peloidal, clotted, or unstructured fabric (predominately layered and poorly structured thrombolite as well as clotted leiolite) (sensu Schmid, 1996). Abundant endo- and epibiontic organisms (bivalves, gastropods, echinoids, asteroids, ophiuroids, crabs etc) are linked to the reefs. With regard to their guild structure, the reefs represent occurrences at which only a few coral species serve as builder. Moreover, microbial carbonates contribute to both building and binding of the reefs. Additional binder as well as baffler are present, but not abundant. According to the species diversity, the dweller guild comprises by far the highest number of invertebrate taxa. The destroyer guild chiefly encompasses bivalves. The composition of the reef community was influenced by the habitat structure of the Th. dendroidea thickets. Owing to the increase in encrusting organisms and other inhabitants of the thickets, the locational factors changed, since light intensity and hydrodynamic energy level and combined parameters as oxygen supply declined in the crowded habitat. Therefore a characteristic succession of organisms is developed that depends on and responds to changing environmental conditions („community replacement sequence“). The succession allows the differentiation of different stages. It started after the cessation of the polyps with boring organisms and photoautotrophic micro-encrusters (calcareous algae, Lithocodium aggregatum). Following the death of these pioneer organisms, encrusting and adherent organisms (serpulids, „Terebella“ species, bryozoans, foraminifers, thecideidinids, sklerospongid and pharetronid sponges, terebratulids), small mobile organisms (limpets), and microbial induced carbonates developed. The final stage in the community replacement sequence gave rise to small cryptic habitats and organisms that belong to these caves (cryptobionts, coelobites). The habitat conditions especially favoured small non-rigid demosponges (“soft sponges”) that tolerate reduced water circulation. Reef rubble is negligible, so that the reefs are bordered by fossiliferous micritic limestone passing laterally in micritic limestone. Approximately 10% of the study area (outcropping florigemma-Bank) corresponds to reefal deposits whereas the remaining 90% encompass lagoonal inter-reefal deposits. The reef development is a good example for the interaction between reef growth, facies development and sea-level changes. It was initiated by a sea-level rise (transgression) and corresponding decrease in the hydrodynamic energy level. Colonization and reef growth took place on a coarse-grained Substrate composed of oncoids, larger foraminifers and bioclasts. Reef growth took place in a calm marine lagoonal setting. Increasing abundance of spherical coral morphs towards the Northeast (section Kessiehausen, northwestem Süntel Mts) reflects higher turbidity and a facies transition to coral occurrences of the ßorigenuna-Bank Member in the adjacent Deister Mts. The reef growth was neither influenced by stonns nor by input of siliciclastic deposits, and took place in short time - probably in only a thousand years under most probably mesotrophic conditions. The mass appearance of solenoporids and nerineids in the upper part of the ßorigenuna-Bank Member point to enhanced nutrient level as a result of regression. In addition, this scenario of fluctuations in nutrient availability seems to be responsible for the cessation of reef corals. The sea level fall reached its climax in the subaerial exposure and palaeokarst development of the florigemma-Bank. The reef building corals are typical pioneer species. The blade-like, flattened F. amchnoides colonies are characterized by their light porous calcium carbonate skeleton, which is a distinct advantage in soft bottom environment. Thus, they settled on soft bottom exposing the large parts of its surface to the incoming light. On the other hand, in response to their light requirements they were also able to settle shaded canopy structures or reef caves. Th. dendroidea is an opportunistic coral species in very shallow, well illuminated marine environment. Their thin and densely spaced branches led to a very high surface/volume ratio of the colonies that were capable to exploit incoming light due to their small thamasterioid calices characterized by “highly integrated polyps”. In addition, sideward coalescence of branches during colony growth led to a wave-resistant framework and favoured the authochthonous preservation of the reefs. Asexual reproduction by fragmented colonies promoted reef development as Th. dendroidea thickets laterally extend over the sea floor or new reefs have developed from broken fragments of parent colonies. Similar build ups with Th. dendroidea as a dominant or frequent reef building coral species are known from the Paris Basin and elsewhere from the Lower Saxony Basin (Kleiner Deister Mts). These buildups developed in well-illuminated shallow water and encompass coral reefs or coral thrombolite reefs. Intra- and inter-reef deposits vary between well-winnowed reef debris limestone and mudstones representing considerably calmer conditions. Solenoporid, nerineids and diceratides belong to the characteristic fossils of these occurrences. However, diceratides are missing in theflorigemma-Bank Member. Th. dendroidea differs in its colonization of low- to high-energy environment from recent ramose scleractinian corals (e.g., Acropora and Porites sp.). The latter are restricted to agitated water habitats creating coral thickets and carpets. According to the morphologic plasticity of Th. dendroidea, thick-branched colonies developed in a milieu of high water energy, whereas fragile, wide- and thin-branched colonies prevail in low-energy settings. Due to its relatively rapid growth, Th. dendroidea was able to keep pace with increased Sedimentation rates. 68 benthonic foraminiferan species/taxa have been recognized in thin sections. Agglutinated foraminifers (textulariids) predominate when compared with rotaliids and milioliids. Numerous species are restricted to a certain facies type or occur in higher population densities, in particular Everticyclammina sp., a larger agglutinated foraminifer that occurs in rock building amounts. Among the 25 reef dwelling foraminiferal species, a few were so far only known from Late Jurassic sponge reefs. Another striking feature is the frequency of adherent foraminiferal species. Fauna and flora, in particular dasycladaleans and agglutinated foraminifers, document palaeobiogeographic relationships to the Tethys and point to (sub)tropical conditions. Moreover, in Germany this foraminiferan assemblage is yet uncompared. In Southern Germany similar tethyan type assemblages are not present in strata as young as Middle Tithonian.

Do teacher stereotypes about school tracks function as expectations at the collective level and do they relate to the perception of obstacles in the classroom and to teachers’ self-efficacy beliefs?

The effects of individual teacher expectations have been the subject of intensive research. Results indicate that teachers use their expectations to adapt their interactions with their students to some degree (as summarized in a review by Jussim & Harber, 2005). This can in turn lead to expectancy-confirming student developments. While there are studies on the Pygmalion effect on individual students, there is only little research on teacher judgements of whole classes and schools. Our study aims to extend the perspective of teacher judgements at the collective level to stereotypes within the context of school tracking. The content and structure of teachers’ school track stereotypes are investigated as well as the question of whether these stereotypical judgements are related to teachers’ perception of obstacles to their teaching and their teaching self-efficacy beliefs. Cross-sectional data on 341 teachers at two different school types from the Panel Study at the Research School „Education and Capabilities“ in North Rhine-Westphalia (PARS) (see Bos et al., 2016) were used for two purposes: First, the structure of teachers’ stereotypes was identified via an exploratory factor analysis. Second, in follow-up regression analyses, the stereotype dimensions extracted were used to predict teachers’ perceptions of obstacles to their classroom work and their individual and collective teacher self-efficacy beliefs. Results showed that – after controlling for the average cognitive abilities and the average cultural capital of the students – teacher stereotypes were indeed related to perceived obstacles concerning their classroom work and their self-efficacy beliefs. After a discussion of the strengths and limitations of the present research, the article closes with a short proposal of a future research framework for collective Pygmalion effects. (DIPF/Orig.)

Prädiktoren der LehrerInnenverantwortung

Der vorliegende Beitrag beschäftigt sich mit der Frage ob Lenks Modell zur Erfassung von grundsätzlichen Determinanten der LehrerInnenverantwortung, das durch Lauermann und Karabenick übernommen wurde, empirisch gestützt werden kann. Ziel dieses Beitrags ist es, kausale Beziehungen innerhalb dieses Modells mit Hilfe eines Strukturgleichungsmodells zu bewerten. Basierend auf Daten einer norwegischen LehrerInnenuntersuchung ergaben sich deutliche Zusammenhänge zwischen den Elementen des Modells. Relationales Vertrauen, informelles Lernen zwischen den LehrerInnen und wahrgenommene Unterstützung durch SchulleiterInnen haben sich als wichtige Determinanten für die LehrerInnenverantwortung erwiesen, wenngleich die kontextuellen Faktoren in ihrer Eigenart komplexer zu sein scheinen. Es bedarf weiterer Forschung, um diese zu verstehen. Angesichts der Ergebnisse ist zu empfehlen, dass Schulbehörden einen Schwerpunkt auf die Gestaltung einer Politik legen, die die Vertrauensbeziehungen zwischen den LehrerInnen berücksichtigt.

Gestaltwandlungen des Imperiums. Heiner Muller und Rom

Die Arbeit schlägt eine systematische Studie der Rezeption des antiken Rom in den Werken von Heiner Müller vor. Die Analyse von Dramen, Gedichten und Essays, sowie von Interviews und Manuskripten, liefert ein umfassendes Bild wiederholter und vielschichtiger Begegnungen mit der römischen Geschichte und Literatur, die bisher weitgehend im kritischen Diskurs im Schatten standen. Der Schwerpunkt der Analyse liegt einerseits auf dem philologisch-literarischen Vergleich mit diesen Quellen und andererseits auf der darauf basierenden Rekonstruktion des umfassenden Bildes eines Imperiums, das seine historischen Grenzen überschreitet, um zu einem zivilisatorischen Prinzip zu werden, so allgegenwärtig wie ambivalent – das "Urbild" einer unauflöslichen Verschränkung von Staat und Gewalt, Kultur und Barbarei, Gesetz und Terror. Diese kulturelle Prägung zeigt sich nicht nur in Werken mit römischem Thema, sondern auch in nachfolgenden historischen Konstellationen, die Müller inszenierte, vom Elisabethanischen England über das Preußen Friedrichs II. bis hin zu den Blöcken des 20. Jahrhunderts. Besondere Aufmerksamkeit wird der Untersuchung literarischer Einflüsse und philosophischer Vorgänger dieser zivilisationskritischen Vision Roms gewidmet – eine Untersuchung, die bestehende Interpretationen korrigiert und neue einführt. Im Lichte des thematischen Komplexes "Rom" wird so ein beträchtlicher Teil von Müllers Produktion neu interpretiert, wodurch ein neues hermeneutisches Paradigma ebenso wie bisher übersehene Einflüsse und intertextuelle Beziehungen bei der Untersuchung von Dramen und Lyrik hervortreten.
