Demokratische Bildung und Beteiligung nahe an den Lebenswelten. Möglichkeiten des Legislativen Theaters

Politische Teilhabe und Raum für Subjektivität gehen Hand in Hand. Menschen in schwierigen und benachteiligten Lebenslagen wird der Raum für unabhängiges, kritisches, politisches Denken und Handeln aufgrund der Prekarität ihres Lebensalltages jedoch zusehends entzogen. Theaterarbeit kann hier ein Ort sein, um (wieder) Zugang zum eigenen Erleben, zu den eigenen Sichtweisen und zur eigenen Sprache zu finden; Beteiligung wird erfahrbar gemacht und soziale Grenzen können überschritten werden. Im Zentrum des vorliegenden Beitrages steht das Legislative Theater nach Augusto Boal, das politische Öffentlichkeit unter Einschluss der "Ausgeschlossenen" ermöglicht und darüber hinaus demokratische Beteiligung eröffnet. Vorgestellt werden Geschichte, Ablauf, aber auch drei konkret von InterACT umgesetzte Beispiele in Österreich und deren nachhaltige politische Einflussnahme. Fazit des Autors: Politisches und demokratisches Lernen entwickeln sich vor allem nahe an den Lebenslagen und Lebenswelten des/der Einzelnen. (DIPF/Orig.)

Panoptikum Bildung – Impulse zur demokratiepolitischen Bildung. Radiosendungen als Beitrag zu zivilgesellschaftlichem Engagement

Die Radiosendung Panoptikum Bildung versteht sich als Medium kritischer Berichterstattung und versucht sozialpolitische Phänomene durch sachliche Informationen aufzubereiten. Die einzelnen Radiobeiträge beleuchten bildungsrelevante Themen aus einem kritischen Blickwinkel, bieten umfassende Hintergrundinformationen und binden FachexpertInnen mit ein. Credo ist: Information statt Infotainment, Gespräch statt Floskeln, Wissensvermittlung anstelle von Talkshowformaten und Dialog statt Konfrontation. In diesem Beitrag, der sich auf bisher unveröffentlichte Jahresberichte der Radiosendereihe stützt, werden das Entstehen und die Leitgedanken sowie die Inhalte und Anliegen einzelner Radiobeiträge vor dem Hintergrund von Oskar Negts theoretischen Überlegungen zu Demokratie und Bildung beschrieben und reflektiert.

[Es] wurden folgende Forschungsfragen entwickelt: (1) Welche Modelle aus den Bezugsdisziplinen der Umweltökonomie und Ökologischen Ökonomie haben hohe Bedeutung in den Fachwissenschaften und sind zugleich anschlussfähig an relevante erziehungswissenschaftliche Forschung sowie curriculare Vorgaben? Was sind Bestandteile dieser fachwissenschaftlichen Schlüsselmodelle, die für eine ökonomische Allgemeinbildung bedeutsam sind? (2) Welche unterschiedlichen Präkonzepte nutzen Studierende der ökonomischen Bildung, wenn sie mit typischen, allgemein verständlich formulierten Problemen aus der Fachwissenschaft konfrontiert werden? (3) Wie können die Erkenntnisse über die fachlichen Modelle und Präkonzepte zur Planung von Seminaren genutzt werden? … Der erste Teil der Arbeit beschäftigt sich mit der Auswahl und Aufarbeitung bedeutsamer Modelle aus den Wirtschaftswissenschaften … Dafür wird einleitend das der Arbeit zugrunde liegende Verständnis ökonomischer Bildung entwickelt … Anschließend werden erziehungswissenschaftliche Forschung sowie curriculare Vorgaben aufgearbeitet und zentrale Forschungsgebiete der Ökologischen Ökonomie und Umweltökonomie identifiziert. Auf dieser Grundlage werden zwei Schlüsselmodelle der relevanten Bezugsdisziplinen bestimmt, nämlich die ökonomische Bewertung und das Management von Ökosystemdienstleistungen (ÖSD) und umweltpolitische Instrumente. … In den Kapiteln 3 und 4 werden die beiden identifizierten Modelle inhaltlich entsprechend der Anforderungen des Literacy-Ansatzes detailliert aufgearbeitet. … Im zweiten Teil der Arbeit werden Präkonzepte, d. h.

Pollen sources of the orchid bee Euglossa annectans Dressler 1982 (Hymenoptera: Apidae, Euglossini) analyzed from larval provisions

In order to analyze the pollen resources used by the orchid bee Euglossa annectans, samples of larval provisions from cells under construction were taken from 12 different trap nests (wooden boxes) on Santa Catarina Island, southern Brazil. The 43 samples collected between 2002 and 2005 represented all months except December. Overall, 74 pollen types from 24 families were distinguished. Among the 26 pollen types that reached more than 10% in monthly means, the families Melastomataceae, Bromeliaceae, Ochnaceae, Fabaceae, and Myrtaceae were most frequently represented. The Shannon-Weaver diversity index H' for the 43 brood cells varied from 0.10-1.65 and the annual diversity was 0.98. Similarity indices ranged from 0 to 0.87 and were highest during spring and summer. The results characterize E. annectans as a polylectic species. Based on these data, we can conclude that Euglossa females may act as pollinators of many forest species.

Forward Neutral-Pion Transverse Single-Spin Asymmetries in p plus p Collisions at s=200 GeV

We report precision measurements of the Feynman x (x(F)) dependence, and first measurements of the transverse momentum (p(T)) dependence, of transverse single-spin asymmetries for the production of pi(0) mesons from polarized proton collisions at s=200 GeV. The x(F) dependence of the results is in fair agreement with perturbative QCD model calculations that identify orbital motion of quarks and gluons within the proton as the origin of the spin effects. Results for the p(T) dependence at fixed x(F) are not consistent with these same perturbative QCD-based calculations.

Survival and Neuronal Differentiation of Mesenchymal Stem Cells Transplanted into the Rodent Brain Are Dependent upon Microenvironment

Introduction: The successful integration of stem cells in adult brain has become a central issue in modern neuroscience. In this study we sought to test the hypothesis that survival and neurodifferentiation of mesenchymal stem cells (MSCs) may be dependent upon microenvironmental conditions according to the site of implant in the brain. Methods: MSCs were isolated from adult rats and labeled with enhanced-green fluorescent protein (eGFP) lentivirus. A cell suspension was implanted stereotactically into the brain of 50 young rats, into one neurogenic area (hippocampus), and into another nonneurogenic area (striatum). Animals were sacrificed 6 or 12 weeks after surgery, and brains were stained for mature neuronal markers. Cells coexpressing NeuN (neuronal specific nuclear protein) and GFP (green fluorescent protein) were counted stereologically at both targets. Results: The isolated cell population was able to generate neurons positive for microtubule-associated protein 2 (MAP2), neuronal-specific nuclear protein (NeuN), and neurofilament 200 (NF200) in vitro. Electrophysiology confirmed expression of voltage-gated ionic channels. Once implanted into the hippocampus, cells survived for up to 12 weeks, migrated away from the graft, and gave rise to mature neurons able to synthesize neurotransmitters. By contrast, massive cell degeneration was seen in the striatum, with no significant migration. Induction of neuronal differentiation with increased cyclic adenosine monophosphate in the culture medium before implantation favored differentiation in vivo. Conclusions: Our data demonstrated that survival and differentiation of MSCs is strongly dependent upon a permissive microenvironment. Identification of the pro-neurogenic factors present in the hippocampus could subsequently allow for the integration of stem cells into nonpermissive areas of the central nervous system.

Cyclic variability of the circumstellar disk of the Be star zeta Tauri I. Long-term monitoring observations

Context. Emission lines formed in decretion disks of Be stars often undergo long-term cyclic variations, especially in the violet-to-red (V/R) ratio of their primary components. The underlying structural and dynamical variations of the disks are only partly understood. From observations of the bright Be-shell star. Tau, the possibly broadest and longest data set illustrating the prototype of this behaviour was compiled from our own and archival observations. It comprises optical and infrared spectra, broad-band polarimetry, and interferometric observations. Aims. The dense, long-time monitoring permits a better separation of repetitive and ephemeral variations. The broad wavelength coverage includes lines formed under different physical conditions, i.e. different locations in the disk, so that the dynamics can be probed throughout much of the disk. Polarimetry and interferometry constrain the spatial structure. All together, the objective is a better understand the dynamics and life cycle of decretion disks. Methods. Standard methods of data acquisition, reduction, and analysis were applied. Results. From 3 V/R cycles between 1997 and 2008, a mean cycle length in Ha of 1400-1430 days was derived. After each minimum in V/R, the shell absorption weakens and splits into two components, leading to 3 emission peaks. This phase may make the strongest contribution to the variability in cycle length. There is no obvious connection between the V/R cycle and the 133-day orbital period of the not otherwise detected companion. V/R curves of different lines are shifted in phase. Lines formed on average closer to the central star are ahead of the others. The shell absorption lines fall into 2 categories differing in line width, ionization/excitation potential, and variability of the equivalent width. They seem to form in separate regions of the disk, probably crossing the line of sight at different times. The interferometry has resolved the continuum and the line emission in Br gamma and HeI 2.06. The phasing of the Br gamma emission shows that the photocenter of the line-emitting region lies within the plane of the disk but is offset from the continuum source. The plane of the disk is constant throughout the observed V/R cycles. The observations lay the foundation for the fully self-consistent, one-armed, disk-oscillation model developed in Paper II.

Beyond the Fragmentation Threshold Hypothesis: Regime Shifts in Biodiversity Across Fragmented Landscapes

Ecological systems are vulnerable to irreversible change when key system properties are pushed over thresholds, resulting in the loss of resilience and the precipitation of a regime shift. Perhaps the most important of such properties in human-modified landscapes is the total amount of remnant native vegetation. In a seminal study Andren proposed the existence of a fragmentation threshold in the total amount of remnant vegetation, below which landscape-scale connectivity is eroded and local species richness and abundance become dependent on patch size. Despite the fact that species patch-area effects have been a mainstay of conservation science there has yet to be a robust empirical evaluation of this hypothesis. Here we present and test a new conceptual model describing the mechanisms and consequences of biodiversity change in fragmented landscapes, identifying the fragmentation threshold as a first step in a positive feedback mechanism that has the capacity to impair ecological resilience, and drive a regime shift in biodiversity. The model considers that local extinction risk is defined by patch size, and immigration rates by landscape vegetation cover, and that the recovery from local species losses depends upon the landscape species pool. Using a unique dataset on the distribution of non-volant small mammals across replicate landscapes in the Atlantic forest of Brazil, we found strong evidence for our model predictions - that patch-area effects are evident only at intermediate levels of total forest cover, where landscape diversity is still high and opportunities for enhancing biodiversity through local management are greatest. Furthermore, high levels of forest loss can push native biota through an extinction filter, and result in the abrupt, landscape-wide loss of forest-specialist taxa, ecological resilience and management effectiveness. The proposed model links hitherto distinct theoretical approaches within a single framework, providing a powerful tool for analysing the potential effectiveness of management interventions.

Cold Nuclear Matter Effects on J/psi Yields as a Function of Rapidity and Nuclear Geometry in d plus A Collisions at root S(NN)=200 GeV

We present measurements of J/psi yields in d + Au collisions at root S(NN) = 200 GeV recorded by the PHENIX experiment and compare them with yields in p + p collisions at the same energy per nucleon-nucleon collision. The measurements cover a large kinematic range in J/psi rapidity (-2.2 < y < 2.4) with high statistical precision and are compared with two theoretical models: one with nuclear shadowing combined with final state breakup and one with coherent gluon saturation effects. In order to remove model dependent systematic uncertainties we also compare the data to a simple geometric model. The forward rapidity data are inconsistent with nuclear modifications that are linear or exponential in the density weighted longitudinal thickness, such as those from the final state breakup of the bound state.

Azimuthal correlations of electrons from heavy-flavor decay with hadrons in p plus p and Au plus Au collisions at root s(NN)=200 GeV

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled p+p collisions. These measurements indicate that charm and bottom quarks interact with the hot dense matter produced in heavy-ion collisions much more than expected. Here we extend these studies to two-particle correlations where one particle is an electron from the decay of a heavy-flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interactions between heavy quarks and the matter, such as whether the modification of the away-side-jet shape seen in hadron-hadron correlations is present when the trigger particle is from heavy-meson decay and whether the overall level of away-side-jet suppression is consistent. We statistically subtract correlations of electrons arising from background sources from the inclusive electron-hadron correlations and obtain two-particle azimuthal correlations at root s(NN) = 200 GeV between electrons from heavy-flavor decay with charged hadrons in p+p and also first results in Au+Au collisions. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to p+p collisions.

Measurement of neutral mesons in p plus p collisions at root s=200 GeV and scaling properties of hadron production

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the invariant differential cross section for production of K(S)(0), omega, eta', and phi mesons in p + p collisions at root s 200 GeV. Measurements of omega and phi production in different decay channels give consistent results. New results for the omega are in agreement with previously published data and extend the measured p(T) coverage. The spectral shapes of all hadron transverse momentum distributions measured by PHENIX are well described by a Tsallis distribution functional form with only two parameters, n and T, determining the high-p(T) and characterizing the low-p(T) regions of the spectra, respectively. The values of these parameters are very similar for all analyzed meson spectra, but with a lower parameter T extracted for protons. The integrated invariant cross sections calculated from the fitted distributions are found to be consistent with existing measurements and with statistical model predictions.
