"Arbeitsweisen im Gegenwartstheater", Band 1 der neuen theaterwissenschaftlichen Reihe, ist im April 2015 im Berliner Alexander Verlag erschienen. Die regelmäßig erscheinenden Ausgaben sind als Arbeitsbücher zu den "itw : im dialog"-Symposien des Instituts für Theaterwissenschaft der Universität Bern konzipiert. Die Beiträge des ersten Bandes reflektieren die komplexen und divergenten Erscheinungsformen zeitgenössischen Theaters und nähern sich aus unterschiedlichen Perspektiven der Frage nach den Zusammenhängen von Arbeitsweisen und Ästhetiken: z. B. Kollektivität und Reflexivität im Gegenwartstheater, Formen und Mobilität internationalisierten Theaters, Allianzen zwischen Freier Szene und Stadttheater sowie Autorenregie. Mit Beiträgen von Annemarie Matzke, Barbara Gronau, Sandra Umathum, Philipp Schulte, Karin Nissen-Rizvani und Gesprächen mit Alexandre Devriendt und Joeri Smet (Ontroerend Goed, Gent), Sebastian Brünger (Rimini Protokoll, Berlin), Tomas Schweigen (FADC/Theater Basel), Sabine Harbeke (Autorin/Regisseurin, Zürich).

Identification and estimation of thresholds in the fixed effects ordered logit model

This paper proposes a new estimator for the fixed effects ordered logit model. In contrast to existing methods, the new procedure allows estimating the thresholds. The empirical relevance and simplicity of implementation is illustrated in an application on the effect of unemployment on life satisfaction.

Varying expectancies and attention bias in phobic and non-phobic individuals.

Phobic individuals display an attention bias to phobia-related information and biased expectancies regarding the likelihood of being faced with such stimuli. Notably, although attention and expectancy biases are core features in phobia and anxiety disorders, these biases have mostly been investigated separately and their causal impact has not been examined. We hypothesized that these biases might be causally related. Spider phobic and low spider fearful control participants performed a visual search task in which they specified whether the deviant animal in a search array was a spider or a bird. Shorter reaction times (RTs) for spiders than for birds in this task reflect an attention bias toward spiders. Participants' expectancies regarding the likelihood of these animals being the deviant in the search array were manipulated by presenting verbal cues. Phobics were characterized by a pronounced and persistent attention bias toward spiders; controls displayed slower RTs for birds than for spiders only when spider cues had been presented. More important, we found RTs for spider detections to be virtually unaffected by the expectancy cues in both groups, whereas RTs for bird detections showed a clear influence of the cues. Our results speak to the possibility that evolution has formed attentional systems that are specific to the detection of phylogenetically salient stimuli such as threatening animals; these systems may not be as penetrable to variations in (experimentally induced) expectancies as those systems that are used for the detection of non-threatening stimuli. In sum, our findings highlight the relation between expectancies and attention engagement in general. However, expectancies may play a greater role in attention engagement in safe environments than in threatening environments.

Does Stepwise Voltage Ramping Protect the Kidney from Injury During Extracorporeal Shockwave Lithotripsy? Results of a Prospective Randomized Trial

BACKGROUND Renal damage is more frequent with new-generation lithotripters. However, animal studies suggest that voltage ramping minimizes the risk of complications following extracorporeal shock wave lithotripsy (SWL). In the clinical setting, the optimal voltage strategy remains unclear. OBJECTIVE To evaluate whether stepwise voltage ramping can protect the kidney from damage during SWL. DESIGN, SETTING, AND PARTICIPANTS A total of 418 patients with solitary or multiple unilateral kidney stones were randomized to receive SWL using a Modulith SLX-F2 lithotripter with either stepwise voltage ramping (n=213) or a fixed maximal voltage (n=205). INTERVENTION SWL. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was sonographic evidence of renal hematomas. Secondary outcomes included levels of urinary markers of renal damage, stone disintegration, stone-free rate, and rates of secondary interventions within 3 mo of SWL. Descriptive statistics were used to compare clinical outcomes between the two groups. A logistic regression model was generated to assess predictors of hematomas. RESULTS AND LIMITATIONS Significantly fewer hematomas occurred in the ramping group(12/213, 5.6%) than in the fixed group (27/205, 13%; p=0.008). There was some evidence that the fixed group had higher urinary β2-microglobulin levels after SWL compared to the ramping group (p=0.06). Urinary microalbumin levels, stone disintegration, stone-free rate, and rates of secondary interventions did not significantly differ between the groups. The logistic regression model showed a significantly higher risk of renal hematomas in older patients (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.00-1.05; p=0.04). Stepwise voltage ramping was associated with a lower risk of hematomas (OR 0.39, 95% CI 0.19-0.80; p=0.01). The study was limited by the use of ultrasound to detect hematomas. CONCLUSIONS In this prospective randomized study, stepwise voltage ramping during SWL was associated with a lower risk of renal damage compared to a fixed maximal voltage without compromising treatment effectiveness. PATIENT SUMMARY Lithotripsy is a noninvasive technique for urinary stone disintegration using ultrasonic energy. In this study, two voltage strategies are compared. The results show that a progressive increase in voltage during lithotripsy decreases the risk of renal hematomas while maintaining excellent outcomes. TRIAL REGISTRATION ISRCTN95762080.

[Spontaneous retropharyngeal hematoma with fatal outcome]

Halsschmerz, Dysphagie und Dyspnoe sind die häufigsten Symptomen, aufgrund derer Patienten einen Arzt aufsuchen. Hierbei handelt es sich um unspezifische Symptome mit vielfältigen Ursachen. Mögliche im Retropharyngealraum lokalisierte Pathologien sind in der überwiegenden Anzahl der Fälle selbst limitierend oder durch medikamentöse Therapien beherrschbar (Bsp.: Pharyngitis, Tonsillitis, Seitenstrangangina). Deutlich seltener sind im Spatium retropharyngeum lokalisierte Abszesse, Neoplasien (Bsp.: Lipome, Neurofibrome, Liposarkome) oder Hämatome (Schmäl F et al. HNO 2002; 50: 418 – 423). Letztlich können auch degenerative Veränderungen der Wirbelsäule, eine ektop verlaufende Arteria carotis interna oder seltene Manifestationen von Systemerkrankungen (Bsp.: Sarkoidose) zu einer unterschiedlich stark ausgeprägten Vorwölbung der Pharynxhinterwand und Einengung der Luft- und Speiseröhre führen. Anhand des vorliegenden Falls wird die klinische Präsentation sowie die radiologische Diagnose eines retropharyngealen Hämatoms diskutiert und die anatomische Beziehung der Halskompartimente mit besonderem Fokus auf den Retropharyngealraum dargestellt.

Roots under attack: contrasting plant responses to below- and aboveground insect herbivory

The distinctive ecology of root herbivores, the complexity and diversity of root–microbe interactions, and the physical nature of the soil matrix mean that plant responses to root herbivory extrapolate poorly from our understanding of responses to aboveground herbivores. For example, root attack induces different changes in phytohormones to those in damaged leaves, including a lower but more potent burst of jasmonates in several plant species. Root secondary metabolite responses also differ markedly, although patterns between roots and shoots are harder to discern. Root defences must therefore be investigated in their own ecophysiological and evolutionary context, specifically one which incorporates root microbial symbionts and antagonists, if we are to better understand the battle between plants and their hidden herbivores.

Independence Day for IgA

IgA is induced through T-cell-dependent and -independent pathways. In this issue, Bunker et al. (2015) now show that the T-cell-independent pathway is sufficient to coat most small intestinal microbes specifically, and Fransen et al. (2015) find that IgA coating promotes uptake of microbes into Peyer's patches and drives further induction in a positive-feedback loop.

The Big Five in Context: Personality, Diversity and Attitudes toward Equal Opportunities for Immigrants in Switzerland

The paper analyzes the link between personality traits and attitudes of Swiss citizens toward equal opportunities for immigrants. In particular, we examine the extent to which this relationship is moderated by the socio-structural context. We test the assumption that the direct links between personality traits and attitudes toward equal opportunities are strengthened by perceived ethnic diversity. Based on our empirical analyses, we are able to replicate central findings of the research on personality traits and attitudes toward immigrants for the Swiss context. While openness toward experience and agreeableness are positively related to a preference for equal opportunities, conscientiousness is negatively linked to these attitudes. Furthermore, our results reveal that the link between conscientiousness and attitudes toward equal opportunities is significantly moderated by the perceived share of foreigners in the neighborhood. This finding is especially relevant for future research on the effects of personality traits.

Study of Basic Wood Decay Mechanisms and Their Biotechnological Applications

The overall objective of this thesis was to gain further understanding of the non-enzymatic mechanisms involved in brown-rot wood decay, especially the role of pH, oxalic acid, and low molecular catecholate compounds on the dissolution and reduction of iron, and the formation of reactive oxygen species. Another focus of this study will be the potential application of a biomimetic free radical generating system inspired from fungi wood decay process, especially the non-enzymatic mechanism. The possible pathways of iron uptake and iron redox cycling in non-enzymatic brown-rot decay were investigated in this study. UV-Vis spectroscopy and HPLC were employed to study the kinetics and pathways of the interaction between iron and model catecholate compounds under different pH and chelator/iron molar ratio conditions. Iron chelation and reduction during early non-enzymatic wood decay processes have been studied in this thesis. The results indicate that the effects of the chelator/iron ratio, the pH, and other reaction parameters on the hydroxyl radical generation in a Fenton type system can be determined using ESR spin-trapping techniques. Data also support the hypothesis that superoxide radicals are involved in chelator-mediated Fenton processes. The mechanisms involved in free radical activation of Thermal Mechanical Pulp fibers were investigated. The activation of TMP fibers was evaluated by ESR measurement of free phenoxy radical generation on solid fibers. The results indicate that low molecular weight chelators can improve Fenton reactions, thus in turn stimulating the free radical activation of TMP fibers. A mediated Fenton system was evaluated for decolorization of several types of dyes. The result shows that the Fenton system mediated by a catecholate-type chelator effectively reduced the color of a diluted solution of synthetic dyes after 90 minutes of treatment at room temperature. The results show that compared to a neat Fenton process, the mediated Fenton decolorization process increased the production, and therefore the effective longevity, of hydroxyl radical species to increase the decolorization efficiency.
