Die europäische Konzernorganisation und die „Europa GmbH“ (SPE) bilden zwei wichtige Forschungsschwerpunkte im Werk von Peter Hommelhoff. Beide Projekte haben sich über die Jahre als außerordentlich dicke Bretter erwiesen. Doch davon lässt sich der Jubilar nicht beirren. Rückschläge und Umwege gehören in der Wissenschaft zum kollektiven Lernprozess, der neue Erkenntnisse bringt. Ganz in diesem Sinne münden die Erfahrungen aus der Diskussion um ein europäisches Konzernrecht und um die SPE im vorliegenden Beitrag in die Konzeption eines supranationalen Konzernbausteins für europäische Unternehmensgruppen.

The Old Babylonian Ištar ritual from Mari (FM 3, no. 2) has been the focus of much discussion since its primary edition in 1938 by G. Dossin. This article offers a new analysis of the passage mentioning the balaĝ-deity Ninigizibara, which leads to identifying this balaĝ as a huge upright lyre as tall as a human played by two persons from both sides. Similar musical instruments are known from Anatolia and Egypt. Especially the Egyptian examples, which are attested only for the time of Echnaton, show striking parallels to the musical performance described in the Old Babylonian Ištar ritual. After discussing the possible background of cultural exchange, this article closes with a revaluation and new interpretation of the term balaĝ.
The three-dimensional cuneiform script is one of the oldest known writing systems and a central object of research in Ancient Near Eastern Studies and Hittitology. An important step towards the understanding of the cuneiform script is the provision of opportunities and tools for joint analysis. This paper presents an approach that contributes to this challenge: a collaborative compatible web-based scientific exploration and analysis of 3D scanned cuneiform fragments. The WebGL -based concept incorporates methods for compressed web-based content delivery of large 3D datasets and high quality visualization. To maximize accessibility and to promote acceptance of 3D techniques in the field of Hittitology, the introduced concept is integrated into the Hethitologie-Portal Mainz, an established leading online research resource in the field of Hittitology, which until now exclusively included 2D content. The paper shows that increasing the availability of 3D scanned archaeological data through a web-based interface can provide significant scientific value while at the same time finding a trade-off between copyright induced restrictions and scientific usability.
Echinocandin antifungals represent one of the most important drug classes for the treatment of invasive fungal infections. The mode of action of the echinocandins relies on inhibition of the β-1,3-glucan synthase, an enzyme essentially required for the synthesis of the major fungal cell wall carbohydrate β-1,3-glucan. Depending on the species, echinocandins may exert fungicidal or fungistatic activity. Apparently independent of this differential activity, a surprising in vitro phenomenon called the “paradoxical effect” can be observed. The paradoxical effect is characterized by the ability of certain fungal isolates to reconstitute growth in the presence of higher echinocandin concentrations, while being fully susceptible at lower concentrations. The nature of the paradoxical effect is not fully understood and has been the focus of multiple studies in the last two decades. Here we concisely review the current literature and propose an updated model for the paradoxical effect, taking into account recent advances in the field.
Although recent developmental studies exploring the predictive power of intelligence and working memory (WM) for educational achievement in children have provided evidence for the importance of both variables, findings concerning the relative impact of IQ and WM on achievement have been inconsistent. Whereas IQ has been identified as the major predictor variable in a few studies, results from several other developmental investigations suggest that WM may be the stronger predictor of academic achievement. In the present study, data from the Munich Longitudinal Study on the Genesis of Individual Competencies (LOGIC) were used to explore this issue further. The secondary data analysis included data from about 200 participants whose IQ and WM was first assessed at the age of six and repeatedly measured until the ages of 18 and 23. Measures of reading, spelling, and math were also repeatedly assessed for this age range. Both regression analyses based on observed variables and latent variable structural equation modeling (SEM) were carried out to explore whether the predictive power of IQ and WM would differ as a function of time point of measurement (i.e., early vs. late assessment). As a main result of various regression analyses, IQ and WM turned out to be reliable predictors of academic achievement, both in early and later developmental stages, when previous domain knowledge was not included as additional predictor. The latter variable accounted for most of the variance in more comprehensive regression models, reducing the impact of both IQ and WM considerably. Findings from SEM analyses basically confirmed this outcome, indicating IQ impacts on educational achievement in the early phase, and illustrating the strong additional impact of previous domain knowledge on achievement at later stages of development.
Past and the projected future climate change in Afghanistan has been analyzed systematically and differentiated with respect to its different climate regions to gain some first quantitative insights into Afghanistan’s vulnerability to ongoing and future climate changes. For this purpose, temperature, precipitation and five additional climate indices for extremes and agriculture assessments (heavy precipitation; spring precipitation; growing season length (GSL), the Heat Wave Magnitude Index (HWMI); and the Standardized Precipitation Evapotranspiration Index (SPEI)) from the reanalysis data were examined for their consistency to identify changes in the past (data since 1950). For future changes (up to the year 2100), the same parameters were extracted from an ensemble of 12 downscaled regional climate models (RCM) of the Coordinated Regional Climate Downscaling Experiment (CORDEX)-South Asia simulations for low and high emission scenarios (Representative Concentration Pathways 4.5 and 8.5). In the past, the climatic changes were mainly characterized by a mean temperature increase above global level of 1.8 °C from 1950 to 2010; uncertainty with regard to reanalyzed rainfall data limited a thorough analysis of past changes. Climate models projected the temperature trend to accelerate in the future, depending strongly on the global carbon emissions (2006–2050 Representative Concentration Pathways 4.5/8.5: 1.7/2.3 °C; 2006–2099: 2.7/6.4 °C, respectively). Despite the high uncertainty with regard to precipitation projections, it became apparent that the increasing evapotranspiration is likely to exacerbate Afghanistan’s already existing water stress, including a very strong increase of frequency and magnitude of heat waves. Overall, the results show that in addition to the already extensive deficiency in adaptation to current climate conditions, the situation will be aggravated in the future, particularly in regard to water management and agriculture. Thus, the results of this study underline the importance of adequate adaptation to climate change in Afghanistan. This is even truer taking into account that GSL is projected to increase substantially by around 20 days on average until 2050, which might open the opportunity for extended agricultural husbandry or even additional harvests when water resources are properly managed.
What does it mean to take animal autobiography seriously and how can we account for the representation of life-narrating animals? The article investigates animal autobiographies as ‘literary autozoographies’, drawing attention to both the generic contexts and the epistemological premises of these texts. Adopting a double-bind approach stemming from autobiographical research as well as cultural animal studies, the article focuses on early nineteenth-century equine autozoographies from the German-speaking tradition. These texts are discussed exemplarily in relation to the parameters of fictional autobiographies, before they are contextualized with historical discourses regarding horses in natural history and so-called ‘horse-science’. Due to the fact that the poetics and aesthetics of the genre are modeled on the templates of factual autobiographies, the article argues that literary autozoographies can be read as fictional autobiographies as well as meta-auto/biographical discourse undermining autobiographical conventions. Furthermore, it shows that literary autozoography and zoology share a common historical and ideological epistemology accounting for the representation of animals in both fields. Literary autozoographies thus participate in the negotiation and production of species-specific knowledge. Reading Life of the Mecklenburg Mare Amante (1804), Life of a Job Horse (1807) and Life of a Worn-Out Hack (1819) alongside equine-centric discourses around 1800, the article demonstrates in what ways these texts can be regarded as part of a regime of knowledge attributing emotions and cognitive capacities to horses, while simultaneously arguing for humane treatment on the basis of interspecies homologies.
