Narcissus and Echo
(2012)
George Eliot’s late novel Daniel Deronda tackles big, fundamental political questions that radiate from the societal circumstances of the novel’s production and reach deep into our present-day life. The novel critically analyses the capitalistic, morally flawed and standard-less English society and narrates the title hero’s proto-Zionist mission to found a Jewish nation that re-establishes history, meaning and ethical values. This study attempts to trace the novel’s two models of society and time by bringing them into resonance with the myth of Narcissus and Echo famously rendered by Ovid. The unloving, self-referential, visual Narcissus is read as the model for the capitalistic world of spectacle and speculation. Echo’s loving, memory-bearing voice forms an important part in the construction of the sublating unity of the Jewish nation-to-come. Guided by this resonance between George Eliot’s novel and Ovid’s myth pieces of critical theory and philosophy are woven into the study’s fabric. The resulting analysis dissects and deconstructs the novel’s fascinating and highly complex patterns of conditions of possibility for the fabrication of the redeeming Jewish nation, the very same conditions that the novel presents as the conditions of possibility for narrating a meaningful story.
Social Closure
(2012)
“Social closure” is one of the most basic terms and concepts in sociology. Basically, closure refers to processes of drawing boundaries, constructing identities, and building communities in order to monopolize scarce resources for one’s own group, thereby excluding others from using them. Society is not a homogenous entity but is instead internally structured and subdivided by processes of social closure. Some social formations, such as groups, organizations, or institutions, may be open to everybody, provided they are capable of participation, while access to most others is limited due to certain criteria that either allow people to become members or exclude them from membership. Therefore, social closure is a ubiquitous, everyday phenomenon that can be observed in almost every sphere and place in the social world. Members of societies experience closure from the very beginning of their social life. To be excluded from certain groups starts at school, where presumably homogenous classes begin to subdivide into distinct peer groups or sports teams. Here, exclusion may be rather arbitrary, but the experience of having a door slammed in one’s face proceeds in cases, where inclusion depends on formal rules or preconditions. Access to private schools follows explicit rules and depends on financial capacities; access to university depends on a certificate or diploma, eventually from certain schools only; membership in a highly prestigious club depends on economic and social capital and the respective social networks; and finally, in the case of migration, people will have to be eligible for citizenship and pass the thorny path of naturalization. However, it is not just the enormous plurality of forms that makes social closure crucial for sociology. Rather, the process of closure of social relations—of groups, organizations, institutions, and even national societies—is the fundamental process of both “communal” (Vergemeinschaftung) and “associative” relationships (Vergesellschaftung), and neither would be possible without social closure. In this broad and fundamental sense, social closure is not restricted to processes in national societies. It even allows for understanding crucial processes of the way the social world is organized at the regional or global level.
Die Koloniale Karibik
(2012)
Werden nicht in der Karibik des 19. Jahrhunderts Phänomene und Prozesse vorweg-genommen, die heute erst ins Bewusstsein gelangen? Der Blick auf die kaleidoskopartige Welt der Karibik über literarische und kulturelle Transprozesse in jener Epoche erlaubt völlig neue Einsichten in die frühen Prozesse der kulturellen Globalisierung. Rassistische Diskurse, etablierte Modelle „weißer“ Abolitionisten, Erinnerungspolitiken und die bisher kaum wahrgenommene Rolle der haitianischen Revolution verbinden sich zu einem Amalgam, das unser gängiges Konzept einer genuin westlichen Moderne in Frage stellt.
Die Erfüllung sicherheitsrelevanter Aufgaben, gerade im Bereich der Wasserversorgung, erfolgt immer vor dem Hintergrund des Schutzes der Kritischen Infrastruktur selbst und eines effektiven Bevölkerungsschutzes. Daher erfordert die Organisation des Schutzes eine über die betriebsbezogene Sichtweise hinausgehende überorganisatorische Betrachtung im Gesamtkontext zunehmender Verflechtung und Abhängigkeiten der Organisationen. Die vorliegende Broschüre richtet sich daher insbesondere an kleine und mittlere Betreiber Kritischer Infrastrukturen, insbesondere im Bereich der Wasserversorgung. Diese sollen in die Lage versetzt werden, eine anforderungsgerechte, skalierbare und vor allem ressourceneffiziente Schutzkonzepterstellung durchführen zu können.
Background/Purpose
Muscular reflex responses of the lower extremities to sudden gait disturbances are related to postural stability and injury risk. Chronic ankle instability (CAI) has shown to affect activities related to the distal leg muscles while walking. Its effects on proximal muscle activities of the leg, both for the injured- (IN) and uninjured-side (NON), remain unclear. Therefore, the aim was to compare the difference of the motor control strategy in ipsilateral and contralateral proximal joints while unperturbed walking and perturbed walking between individuals with CAI and matched controls.
Materials and methods
In a cross-sectional study, 13 participants with unilateral CAI and 13 controls (CON) walked on a split-belt treadmill with and without random left- and right-sided perturbations. EMG amplitudes of muscles at lower extremities were analyzed 200 ms after perturbations, 200 ms before, and 100 ms after (Post100) heel contact while walking. Onset latencies were analyzed at heel contacts and after perturbations. Statistical significance was set at alpha≤0.05 and 95% confidence intervals were applied to determine group differences. Cohen’s d effect sizes were calculated to evaluate the extent of differences.
Results
Participants with CAI showed increased EMG amplitudes for NON-rectus abdominus at Post100 and shorter latencies for IN-gluteus maximus after heel contact compared to CON (p<0.05). Overall, leg muscles (rectus femoris, biceps femoris, and gluteus medius) activated earlier and less bilaterally (d = 0.30–0.88) and trunk muscles (bilateral rectus abdominus and NON-erector spinae) activated earlier and more for the CAI group than CON group (d = 0.33–1.09).
Conclusion
Unilateral CAI alters the pattern of the motor control strategy around proximal joints bilaterally. Neuromuscular training for the muscles, which alters motor control strategy because of CAI, could be taken into consideration when planning rehabilitation for CAI.
Flux-P
(2012)
Quantitative knowledge of intracellular fluxes in metabolic networks is invaluable for inferring metabolic system behavior and the design principles of biological systems. However, intracellular reaction rates can not often be calculated directly but have to be estimated; for instance, via 13C-based metabolic flux analysis, a model-based interpretation of stable carbon isotope patterns in intermediates of metabolism. Existing software such as FiatFlux, OpenFLUX or 13CFLUX supports experts in this complex analysis, but requires several steps that have to be carried out manually, hence restricting the use of this software for data interpretation to a rather small number of experiments. In this paper, we present Flux-P as an approach to automate and standardize 13C-based metabolic flux analysis, using the Bio-jETI workflow framework. Exemplarily based on the FiatFlux software, it demonstrates how services can be created that carry out the different analysis steps autonomously and how these can subsequently be assembled into software workflows that perform automated, high-throughput intracellular flux analysis of high quality and reproducibility. Besides significant acceleration and standardization of the data analysis, the agile workflow-based realization supports flexible changes of the analysis workflows on the user level, making it easy to perform custom analyses.
The reaction of the German labor market to the Great Recession 2008/09 was relatively mild – especially compared to other countries. The reason lies not only in the specific type of the recession – which was favorable for the German economy structure – but also in a series of labor market reforms initiated between 2002 and 2005 altering, inter alia, labor supply incentives. However, irrespective of the mild response to the Great Recession, there are a number of substantial future challenges the German labor market will soon have to face. Female labor supply still lies well below that of other countries and a massive demographic change over the next 50 years will have substantial effects on labor supply as well as the pension system. In addition, due to a skill-biased technological change over the next decades, firms will face problems of finding employees with adequate skills. The aim of this paper is threefold. First, we outline why the German labor market reacted in such a mild fashion, describe current economic trends of the labor market in light of general trends in the European Union, and reveal some of the main associated challenges. Thereafter, the paper analyzes recent reforms of the main institutional settings of the labor market which influence labor supply. Finally, based on the status quo of these institutional settings, the paper gives a brief overview of strategies to combat adequately the challenges in terms of labor supply and to ensure economic growth in the future.
Cell-level kinetic models for therapeutically relevant processes increasingly benefit the early stages of drug development. Later stages of the drug development processes, however, rely on pharmacokinetic compartment models while cell-level dynamics are typically neglected. We here present a systematic approach to integrate cell-level kinetic models and pharmacokinetic compartment models. Incorporating target dynamics into pharmacokinetic models is especially useful for the development of therapeutic antibodies because their effect and pharmacokinetics are inherently interdependent. The approach is illustrated by analysing the F(ab)-mediated inhibitory effect of therapeutic antibodies targeting the epidermal growth factor receptor. We build a multi-level model for anti-EGFR antibodies by combining a systems biology model with in vitro determined parameters and a pharmacokinetic model based on in vivo pharmacokinetic data. Using this model, we investigated in silico the impact of biochemical properties of anti-EGFR antibodies on their F(ab)-mediated inhibitory effect. The multi-level model suggests that the F(ab)-mediated inhibitory effect saturates with increasing drug-receptor affinity, thereby limiting the impact of increasing antibody affinity on improving the effect. This indicates that observed differences in the therapeutic effects of high affinity antibodies in the market and in clinical development may result mainly from Fc-mediated indirect mechanisms such as antibody-dependent cell cytotoxicity.
