The Gradient Symbolic Computation (GSC) model presented in the keynote article (Goldrick, Putnam & Schwarz) constitutes a significant theoretical development, not only as a model of bilingual code-mixing, but also as a general framework that brings together symbolic grammars and graded representations. The authors are to be commended for successfully integrating a theory of grammatical knowledge with the voluminous research on lexical co-activation in bilinguals. It is, however, unfortunate that a certain conception of bilingualism was inherited from this latter research tradition, one in which the contrast between native and non-native language takes a back seat.
Die vorliegende Arbeit befasst sich mit Führungsverhalten im öffentlichen Sektor sowie mit Einflussfaktoren auf dieses Führungsverhalten. Hierzu wurde eine Taxonomie, bestehend aus sechs Metakategorien von Führungsverhalten, entwickelt. Die Metakategorien umfassen Aufgaben-, Beziehungs-, Veränderungs-, Außen-, Ethik- und Sachbearbeitungsorientierung. Eine Analyse von Umfragedaten, die für diese Arbeit bei Mitarbeitern und unteren Führungskräften dreier Behörden erhoben wurden, zeigt, dass diese Taxonomie sehr gut geeignet ist, die Führungsrealität in der öffentlichen Verwaltung abzubilden.
Eine deskriptive Auswertung der Daten zeigt außerdem, dass es eine relativ große Differenz zwischen der Selbsteinschätzung der Führungskräfte und der Fremdeinschätzung durch ihre Mitarbeiter gibt. Diese Differenz ist bei der Beziehungs- und Veränderungsorientierung besonders hoch.
Der deskriptiven Auswertung schließt sich eine Analyse von Einflussfaktoren auf das Führungsverhalten an. Die Einflussfaktoren können den vier Kategorien "Charakteristika und Eigenschaften der Führungskräfte", "Erwartungen und Interesse von Vorgesetzten", "Charakteristika und Einstellungen von Geführten" und "Managementinstrumente und -rahmenbedingungen" zugeordnet werden.
Eine Analyse mit Hilfe von hierarchischen linearen Modellen zeigt, dass vor allem die Führungsmotivation und die Managementorientierung der Führungskräfte, die Gemeinwohlorientierung und die Art der Aufgabe der Geführten sowie die strategische Führungskräfteauswahl und die Leistungsmessung durch die Führungskräfte anhand konkreter Ziele einen Einfluss auf das Führungsverhalten haben.
Die Ergebnisse dieser Arbeit ergänzen die Literatur zu Führungsverhalten im öffentlichen Sektor um die Perspektive der Einflussfaktoren auf das Führungsverhalten und leisten zusätzlich mit Hilfe der verwendeten Taxonomie einen Beitrag zur theoretischen Diskussion von Führungsverhalten in der Public-Management-Forschung. Darüber hinaus bieten die gewonnenen Erkenntnisse der Verwaltungspraxis Hinweise zu relevanten Einflussfaktoren auf das Führungsverhalten sowie auf beachtliche Differenzen zwischen Selbst- und Fremdwahrnehmung des Führungsverhaltens.
This article is a response to calls in prior research that we need more longitudi-nal analyses to better understand the foundations of PSM and related prosocial values. There is wide agreement that it is crucial for theory-building but also for tailoring hiring practices and human resource development programs to sort out whether PSM-related values are stable or developable. The article summarizes existent theoretical expecta-tions, which turn out to be partially conflicting, and tests them against multiple waves of data from the German Socio-Economic Panel Study which covers a time period of sixteen years. It finds that PSM-related values of public employees are stable rather than dynamic but tend to increase with age and decrease with organizational member-ship. The article also examines cohort effects, which have been neglected in prior work, and finds moderate evidence that there are differences between those born during the Second World War and later generations.
Introduction
Genes involved in body weight regulation that were previously investigated in genome-wide association studies (GWAS) and in animal models were target-enriched followed by massive parallel next generation sequencing.
Methods
We enriched and re-sequenced continuous genomic regions comprising FTO, MC4R, TMEM18, SDCCAG8, TKNS, MSRA and TBC1D1 in a screening sample of 196 extremely obese children and adolescents with age and sex specific body mass index (BMI) >= 99th percentile and 176 lean adults (BMI <= 15th percentile). 22 variants were confirmed by Sanger sequencing. Genotyping was performed in up to 705 independent obesity trios (extremely obese child and both parents), 243 extremely obese cases and 261 lean adults.
Results and Conclusion
We detected 20 different non-synonymous variants, one frame shift and one nonsense mutation in the 7 continuous genomic regions in study groups of different weight extremes. For SNP Arg695Cys (rs58983546) in TBC1D1 we detected nominal association with obesity (p(TDT) = 0.03 in 705 trios). Eleven of the variants were rare, thus were only detected heterozygously in up to ten individual(s) of the complete screening sample of 372 individuals. Two of them (in FTO and MSRA) were found in lean individuals, nine in extremely obese. In silico analyses of the 11 variants did not reveal functional implications for the mutations. Concordant with our hypothesis we detected a rare variant that potentially leads to loss of FTO function in a lean individual. For TBC1D1, in contrary to our hypothesis, the loss of function variant (Arg443Stop) was found in an obese individual. Functional in vitro studies are warranted.
Die Rezeption des Propheten Jona im Koran setzt dessen biblischen Narrativ im Wesentlichen voraus und deutet diesen vor allem dort aus, wo man um eine Korrektur seines Prophetenbildes bemüht ist. Im Fokus stehen dabei die Buße, Umkehr und Erlösung Yūnus’ und seines Volkes. Nachkoranische Prophetenerzählungen (qisas alanbiyā’) füllen die narrativen Leerstellen der ‚Jona-Suren‘ wiederum mit erklärendem Erzählmaterial auf und schöpfen dafür auch aus dem umfangreichen Fundus biblischer und rabbinischer Traditionen, die sie sich im äußeren Rahmen der koranischen Yūnus Überlieferung schöpferisch zu eigen machen. So entstehen Erzählkompositionen, die sich als dialogische Auseinandersetzung mit religiösen Themen von gemeinsamer Relevanz lesen lassen. Der Artikel reflektiert gezielt Entwicklung und Verhältnis der Rezeptionen Jonas im Koran sowie in den Prophetenerzählungen von Ibn-Muhammad at-Ta‛labī und Muhammad ibn ‛Abd Allāh al-Kisā’i, in stetiger Auseinandersetzung mit der jüdischen Jona-Tradition.
Lake Towuti is a tectonic basin, surrounded by ultramafic rocks. Lateritic soils form through weathering and deliver abundant iron (oxy)hydroxides but very little sulfate to the lake and its sediment. To characterize the sediment biogeochemistry, we collected cores at three sites with increasing water depth and decreasing bottom water oxygen concentrations. Microbial cell densities were highest at the shallow site a feature we attribute to the availability of labile organic matter (OM) and the higher abundance of electron acceptors due to oxic bottom water conditions. At the two other sites, OM degradation and reduction processes below the oxycline led to partial electron acceptor depletion. Genetic information preserved in the sediment as extracellular DNA (eDNA) provided information on aerobic and anaerobic heterotrophs related to Nitrospirae. Chloroflexi, and Therrnoplasmatales. These taxa apparently played a significant role in the degradation of sinking OM. However, eDNA concentrations rapidly decreased with core depth. Despite very low sulfate concentrations, sulfate-reducing bacteria were present and viable in sediments at all three sites, as confirmed by measurement of potential sulfate reduction rates. Microbial community fingerprinting supported the presence of taxa related to Deltaproteobacteria and Firmicutes with demonstrated capacity for iron and sulfate reduction. Concomitantly, sequences of Ruminococcaceae, Clostridiales, and Methanornicrobiales indicated potential for fermentative hydrogen and methane production. Such first insights into ferruginous sediments showed that microbial populations perform successive metabolisms related to sulfur, iron, and methane. In theory, iron reduction could reoxidize reduced sulfur compounds and desorb OM from iron minerals to allow remineralization to methane. Overall, we found that biogeochemical processes in the sediments can be linked to redox differences in the bottom waters of the three sites, like oxidant concentrations and the supply of labile OM. At the scale of the lacustrine record, our geomicrobiological study should provide a means to link the extant subsurface biosphere to past environments.
The present work is a case study contributing to the major planning project “Suedlink”. It is structured as follows: first, in a theoretical part, mandatory theories of social acceptance (Wüstenhagen et al., 2007), steps of participation (Münnich, 2014), and the governance theory (Benz and Dose, 2011) are elaborated. Secondly, the relevant methods are discussed. Thirdly, in a qualitative analytical part, the information that were gathered from the expert interviews are analyzed with the use of the aforementioned theories. In the fourth place, an empirical quantitative analysis of data regarding the public acceptance towards Suedlink is presented.
In this case study, with the use of qualitative and quantitative methods, two questions are answered: first, which governance aspects were relevant for the priority use of underground cables for the construction of high voltage direct current transmission lines? For this question, intensive document analysis and different expert interviews were conducted. Secondly, the central question of the present work addresses the question whether local or/and individual factors affect the public acceptance towards SüdLink. Here, in particular, it is interesting to analyze if the priority use of underground cables affected the people’s acceptance towards SuedLink. In order to respond to both questions, an online survey was conducted among citizen initiatives, district administrators, and individuals in social media during March till July 2016. Thereafter, the data was analyzed with the use of descriptive quantitative methods. The data shows, that underground cables not necessarily increase public acceptance (see also Menges and Beyer, 2013). On the contrary, individual and local criteria were relevant for the survey respondents. For example criteria such as the quality of participation, distance between home and transmission lines, and the additional financial burden (taxes, higher prices for electricity) were important for the evaluation. In addition, survey respondents who participated in citizen initiatives were more critical against the priority use of underground cables and SuedLink in general. Likewise, residential homeowners rejected every form of transmission lines.
