Between immersion and media reflexivity: virtual travel media in the 19th century
2016-01-01

Deviating from Oliver Grau’s notion of the panorama’s immersive features, this article will discuss the receptive impact of virtual travel media of the 19th century in a more ambivalent and nuanced manner by employing two theoretical texts by Walter Benjamin, Clemens Brentano and Heinrich von Kleist. In Berlin Childhood around 1900 Benjamin draws on and reflects his childhood experience of the Kaiserpanorama in Berlin. Brentano and Kleist’s text elucidates the authors’ ‘strange feeling’ towards Caspar David Friedrich’s painting Monk by the Sea. What both texts share is a fundamental experience of ambivalence regarding the topographies depicted in both media. Other than merely being ‘enchanted’ and taken into a far distant land, it is precisely the mediality of the Kaiserpanorama and the Friedrich painting that provides a more complex experience, oscillating between distance and familiar terrain, between immersion and media reflexivity, between past, present and future. After introducing and discussing both theoretical accounts, I will apply their receptive principles to the analysis of the virtual travel media panorama and early cinema.
Diffusion, Coulombic interactions and multicomponent ionic transport of charged species in saturated porous media
2016-01-01

Diffusion and compound-specific mixing significantly affect conservative and reactive transport in groundwater at different scales, not only under diffusion-dominated regimes but also under advection-dominated flow through conditions [1]. When dissolved species are charged, besides the magnitude of their aqueous diffusion coefficients also the electrostatic interactions significantly affect solute displacement. We investigated electrostatic interactions between ionic species under flow-through conditions resulting in multicomponent ionic dispersion: the dispersive fluxes of the different ions in the pore water are cross-coupled due to the effects of Coulombic interactions. Such effects are illustrated in flow-through experiments in saturated porous media. Simple strong electrolytes (i.e., salts and strong acid solutions) were selected as tracers and their transport was studied under different advection-dominated conditions in homogeneous and heterogeneous porous media [2-3]. The model-based interpretation of the experimental results is challenging since it requires a multicomponent ionic formulation with an accurate description of local hydrodynamic dispersion and explicitly accounting for the cross-coupling of dispersive fluxes due to the Coulombic interactions between the ions in the pore water [4-5].
Diffusive-dispersive mass transfer in the capillary fringe: Impact of water table fluctuations and heterogeneities
2016-01-01

Diffusive–dispersive mass transfer in the capillary fringe is important for many groundwater quality issues such as transfer of volatile compounds into (and out of) the groundwater, the supply of oxygen for aerobic degradation of hydrocarbons as well as for precipitation of minerals (e.g. iron hydroxides). 2D-laboratory scale experiments were used to investigate the transfer of oxygen into groundwater under non-reactive and reactive conditions, at steady state and with water table fluctuations. Results show that transfer of oxygen is limited by transverse dispersion in the capillary fringe and the dispersion coefficients are the same as below the water table. Water table fluctuations cause temporarily increased fluxes of oxygen into groundwater during draining conditions and entrapped air after water table rise. High-permeability inclusions in the capillary fringe enhance mass transfer of oxygen to the underlying anoxic groundwater by increased dispersion due to flow focusing and by significant air trapping in the coarse material inclusions.
Technological complexity’s impact on the sustainability of competitive advantage from innovation
2016-01-01

Firms outperforming their competitors face imitation and substitution of their innovations which theoretically erodes their competitive advantage. Based on resource based theory we investigate the influence of substitution and imitation on the sustainability of firms’ competitive advantage constituted by innovations as knowledge based resources. We analyze their influence on the continuous outperformance of firms differentiating between complex and discrete technologies and product and process innovation. Our findings refine and enhance previous research in this area and advance our knowledge on imitation’s and substitution’s relevance and impact on sustained competitive advantage in different contexts. We contribute the important moderating influence of technology complexity within the resource based view and highlight the limited explanatory power of this theory for highly complex technologies. We provide extensive discussions of these implications.
Antecedents and Consequences of Trust Development Across Hierarchical and Cross-Cultural Boundaries
2016-01-01

Enriching interpersonal cross-cultural trust literature with acculturation theory, our explorative, qualitative study reveals how (collectivist) Chinese subordinates either succeed or fail in forming and developing trust to their (individualist) German supervisors. Our analysis is based on 90 semi-structured interviews with Chinese subordinates of German supervisors and German supervisors of Chinese subordinates both in China and in Germany. Our findings illuminate how Chinese subordinates develop (or lose) trust in German supervisors over three phases (contact, disillusion and acculturation), ultimately resulting in either establishment or erosion of trust. Our findings disclose that central propositions of seminal (Western) trust concepts are turned upside down, once the focus moves from an exclusively Western cultural context to one that includes also Asian contexts. As such, our study uncovers important boundary conditions of influential trust concepts.
The mismeasurement of mind: How neuropsychological testing creates a false picture of cognitive aging.
2016-01-01

Age-related declines in scores on neuropsychological tests arewidely believed to reveal that human cognitive capacitiesdecline across the lifespan. In a computational simulation, weshow how the behavioral patterns observed in PairedAssociate Learning (PAL), a particularly sensitive measure ofage-related performance change (Rabbitt &amp;amp; Lowe, 2000), arepredicted by the models used to formalize associative learningprocesses in other areas of behavioral and neuroscientificresearch. The simulation further predicts that manipulatinglanguage exposure will reproduce the experience-relatedperformance differences erroneously attributed to age-relateddecline in age-matched adults. Consistent with this, olderbilinguals outperformed native speakers in a German PALtest, an advantage that increased with age. These analyses andresults show that age-related PAL performance changesreflect the predictable effects of learning on the associabilityof test items, and indicate that failing to control for theseeffects is distorting our understanding of cognitive and braindevelopment in adulthood.
Spirituality and Religion and the Pursuit of Meaningfulness in Organizational Life
2016-01-01

In this symposium each panelist will explore how they find meaning in their work and, in doing so, play a part in making their organizations meaningful. Given the essence of meaning is connection and is inherently spiritual as it is a nonphysical reality, we believe it fruitful to examine how people satisfy Baumeister’s four needs for meaning at work (need for purpose, values, efficacy, and self-worth) through a wide spectrum of religious and nonreligious traditions, perspectives, and practices including Christianity, Judaism, Islam, Buddhism, Hinduism, 12 Step spiritual programs, humanistic management, and atheism. In particular, symposium panelists will elaborate on how meaningfulness can foster maximization/realization of human potential at work and how these different framings illuminate the processes of making organizations meaningful.
How embodied is action verb processing? Exploring the limits of effector-specific compatibility effects
2016-01-01

According to the experiential-traces account, which is part of the embodied cognition framework, language comprehension is based on the reactivation of experiential traces that stem from experiencing the corresponding objects, states, or events. Behavioural research finds support for this theory in interactions between language and motor processing. However, previous research focusing on action verb processing produced mixed results. To further address this issue, we investigated effector-specific compatibility effects in four experiments by comparing results of a lexical decision task with those of a Stroop-like task. We found effector-specific activation for nouns in a variety of different conditions (tasks, stimulus sets). Compatibility effects for action verbs, in contrast, were highly task and stimulus set dependent. These results are problematic for embodied accounts of language comprehension, according to which the reactivation of experiential traces is a necessary component of language comprehension. unpublished
From France to Saxony – Painted pebbles from Le Mas d’Azil (Ariège) in the archaeological collections from Saxony
2016-01-01

This contribution presents about 30 painted pebbles from Le Mas d’Azil which have been recently detected in the Staatliches Museum für Archäologie à Chemnitz (Germany). This study retraces the history of these pieces since their discovery at the site and demonstrates that they have been directly donated, in 1899, by the excavator Édouard Piette to the royal collection of prehistory at Dresden. The identification of their origin makes it unlikely that they represent forgeries and offer an important addendum to the existing inventory of these emblematic pieces of French prehistory.
Sculptures as the Trademark of Sovereignty in the Hoysaḷa Kingdom
2016-01-01

Among the various sculptures created by Hoysaḷa artists between the 12th and 13th centuries emerges a curious iconographic couple: a man wearing a long robe and an unusual headdress, accompanied by a woman, completely naked, with sandals on her feet, surrounded by snakes. Both these figures have a stick. The recurrence of this subject in many temples and the important position in the register of sculptures suggest that this iconography was already codified in the early 12th century, that is during the rise of the dynasty. The focus of my study is to analyze the development of these representations in correlation with the religious and political context: at the beginning the two iconographies were sculpted together, while in the course of time they began to be carved separately. This new exploration adds to the iconographic analysis and the study of the epigraphic sources and it aims at relating the artistic production with the construction and legitimation of the dynasty. Controversial interpretations of the meaning of these representations open up a lively debate about local cults in medieval Karnataka and the versatile royalty of the Hoysaḷa dynasty.
Influence of organ transplant controversies on corneal donation rates
2016-01-01

Aim: This study aimed to investigate the influence of organ transplant controversies on corneal donation rates at the University Hospital Tübingen. Methods:Data from all hospital deaths from 2009 to 2015 were analyzed.During the 7-year period two vast German organ donor controversies occurred in the end of 2012 and 2014.An ophthalmic resident handled on a full-time basis the corneal donor procurement with stable methods.The rates of corneal donation were examined and evaluated.Results: Among the 5712 deaths, consent for corneal donation was obtained in 711 cases.The mean annual corneal donation rate was 12.4% (range: 8.7% -17.8%).Since 2009, the donation rate per year could be increased with exception of 2013 and 2015.In the end of 2012 and 2014 two vast German organ donor controversies received worldwide attention.In the following years 2013 and 2015 corneal donation rate decreased significantly (P=0.02 and P=0.0006). Conclusion:German law regarding tissue collection is based on previous informed consent from the donor through a standard donor card or through verbal or written consent.
Performance Analysis of CoDel and PIE for Saturated TCP Sources
2016-01-01

In the recent years, the bufferbloat phenomenon was observed which is mainly due to oversized unmanaged buffers in the Internet. This triggered a new discussion of active queue management (AQM) algorithms in the IETF. Controlled Delay (CoDel) and Proportional Integral controller Enhanced (PIE) are considered as an alternative to Random Early Detection (RED). Their intention is both to take advantage of large buffers for occasional bursts and to limit queueing delays most of the time. Moreover, they are able to cope with varying bandwidth. In this paper, we study the performance of CoDel, PIE, and CoDel-ACT, which is an effective modification of CoDel that leads to better performance than CoDel in our studies. We experiment with saturated TCP sources and a fixed-bandwidth bottleneck link and focus on the delay-limiting phase of the algorithms. We investigate the impact of configuration parameters and traffic load on link utilization and queueing delay. We study the timely evolution of queuing delays and drop patterns, and point out significant differences among the algorithms. In particular, we show that CoDel's drop behavior changes over time and may lead to underutilization.
Demo: Resilient Integration of Distributed High-Performance Zones into the BelWue Network Using OpenFlow.
2016-01-01

The Internet service provider (ISP) BelWue interconnects higher education and research institutions in Baden-Wuerttemberg, Germany. Its 10 Gb/s backbone among university campuses has been augmented with an additional optical 100~Gb/s high-speed network called NeIF. The bwNET100G+ project sets up special high-performance zones (HPZ) at a few university campuses and seeks for cost-efficient interconnection over the NeIF and integration into the legacy infrastructure. We propose for that purpose SDN-NeIF, a software-defined network architecture leveraging OpenFlow and iBGP. The demo illustrates this concept for three university locations with a special focus on resiliency. It leverages a virtualized testbed consisting of four desktop PCs and three consumer switches. The demo validates the SDN-NeIF architecture and serves as a first proof-of-concept.
Pneumothorax Ex Vacuo by Severe pleuramesothelioma
2016-01-01

Pneumothorax ex vacuo is a rare type of pneumothorax which forms adjacent to an atelectatic lobe.Pneumothorax ex vacuo occurs if the underlying lung is unable to expand, for example due to bronchial obstruction under severe pleuramesothelioma.In this situation, the pleural effusion was caused by lung collapse, leading to negative pressure in the pleura which gradually pulled in fluid.The primary problem is not the pleural effusion, but rather the fact that the lung cannot expand.Our patient has severe pleuramesothelioma.The palliative chemotherapy was already initiated.Due to progressive dyspnea, a thoracentesis with implication of pleurX-catheter was performed in this situation.
Válka jako stvořitelka a ničitelka národů, národních států a impérií. Evropská zkušenost od napoleonské éry / War as the creator and destroyer of nations, nation-states and empires. The european experience since the napoleonic era
2016-01-01

This study examines the role of war in the processes of decay and emergence of nations, nation-states and empires in Europe from the Napoleonic wars to the First World War. Throughout the period under review up to 1914 no nation-state emerged in Europe without conflict. The war was often related to the notions of European nations and national movements regarding progress and achievement of global dominance in Europe in those days.
Whither local governance in contemporary China? Reconfiguration for more effective policy implementation
2016-01-02

This article describes China's reorganization of its local governance system since the early 2000s. Policy shifts, administrative restructuring and intensified public inclusion have considerably modified local governance, especially in the country's vast rural areas and, we argue, have laid the groundwork for continuous and more effective policy implementation amidst increasing complexity and challenges. Based on years of fieldwork on new rural development policies, urbanization programs and private sector development in China, we start by briefly describing the most important developments in local governance, especially at the county level and below. We then concentrate on two aspects with particular relevance: first, we trace the reconfigured characteristics of internal governmental procedures of policy adjustment and implementation. Second, we find new types of external stakeholder inclusion, which we analyze based on the example of local government interactions with private entrepreneurs in promoting development blueprints and strengthening public goods provision. In conclusion, we contend that current Chinese local governance is a dynamic and delicate combination of expanding local administrative autonomy, external actor inclusion and the Party State's re-emergent aim of pervasive steering. At a minimum, the resulting governance arrangements appear able to generally strengthen the political regime's implementation capacities.
New Middle Palaeolithic sites from the Mani Peninsula, Southern Greece
2016-01-02

We here report the first results from a systematic research project in Mani (Southern Greece), which includes survey and test excavations. Forty-six caves, rockshelters and open-air sites in lowland settings were surveyed. Geomorphological data were collected in order to assess how geological processes affect the preservation of sites and bias site distribution patterns. Artifacts manufactured from non-local rock indicate potential raw material transfers and suggest links among the different regions of Mani, related to mobility patterns. Our research in the Mani has nearly doubled the number of known Middle Palaeolithic sites from the region and confirmed that the peninsula has the strongest 'Neanderthal signal' identified to date in Greece. Almost all sites are located at coastal areas. Despite the influence of Pleistocene landscape dynamics, this distribution emerges as a persistent pattern, perhaps indicating a preference for coastal locations. The Neanderthal occupation of Mani can illuminate important aspects of Middle Palaeolithic adaptation in one of the southernmost coastal regions of Europe.
Nests of the soil dwelling sweat beeAugochloropsis caerulans(Hymenoptera: Halictinae) in a waterlogged environment in southern Brazil
2016-01-02

A swampy nest site of the sweat bee Augochloropsis caerulans (Vachal, 1903) in southern Brazil is reported. The bees colonized small earth mounds scattered throughout a water-covered area. Although the substrate of these mounds has high organic matter content, the risk of microbial infestation seems not to be enhanced owing to permanent water saturation. The nests are shallow and can be found 3 cm above the water table. Each nest consists of a cluster of vertically oriented cells on pillars in an oval shaped cavity. The specific nest architecture is thought to mitigate microbial infestation of the brood and to prevent water excess. Nests of A. caerulans are not restricted to water-saturated substrates, but the specific nest architecture presumably enables the bee to propagate in such habitats.
Simulation of Wing and Nacelle Stall
2016-01-02

Numerical stall simulations are challenging in terms of physical models involved, overall computation effort, and the needed efforts for validation. The present paper describes coordinated, fundamental research into new simulation methodologies and their validation for wing and nacelle stall that also include the effects of atmospheric gusts. The research is&#13;\\ncarried out by the DFG funded Research Unit FOR 1066, which is composed of German Universities and the German Aerospace Center, DLR. The Research Unit investigates advanced models of turbulence, advanced physics-based gust models, and new numerical approaches for gust simulation. These modeling and computational activities are &#13;\\nsupplemented by new validation experiments, that aim at providing stall data on wings and engine nacelles with well defined, generic distortions of the onset flow.
The Emergence and Use of GPS Electronic Monitoring in Germany: Current Trends and Findings
2016-01-02

In Germany, Electronic Monitoring (EM) is currently applied in two different areas. As of 2000, in the German state of Hesse, Radio Frequency (RF) EM has been used for probationers to avoid (re)imprisonment. Approximately 4 years ago, a federal law came into force allowing for Global Positioning System (GPS) EM of high-risk offenders after prison release. In spite of these ongoing areas of application, a pilot project featuring GPS-EM of prisoners was carried out as a means of release preparation in the German state of Baden-Württemberg from October 2010 until March 2012. This article gives an overview of the different areas of application of EM in Germany and analyzes its nationwide use. Furthermore, the rationale and the outcome of the pilot project in Baden-Württemberg are presented in detail. In conclusion, the authors raise serious doubts about the rehabilitative potential of EM with respect to the current evaluative findings.
A Derivative of the Blatter Radical as a Potential Metal-Free Magnet for Stable Thin Films and Interfaces
2016-01-04

Organic radicals are fascinating materials because of their unique properties, which make them suitable for a variety of applications. Their synthesis may be challenging, and big efforts have focused on chemical stability. However, introducing a new material in electronics not only requires chemically stable molecules but also stable monolayers and thin films in view of their use in devices. In this work, we have investigated the thin films of a derivative of the Blatter radical that was synthesized bearing in mind the thermodynamic factors that govern thin film stability. We have proved our concept by investigating the electronic structure, the paramagnetic character, and stability of the obtained films under UHV and ambient conditions by in situ X-ray photoelectron spectroscopy, ex situ atomic force microscopy, and electron paramagnetic resonance spectroscopy.
Coordinating Role of RXRα in Downregulating Hepatic Detoxification during Inflammation Revealed by Fuzzy-Logic Modeling
2016-01-04

During various inflammatory processes circulating cytokines including IL-6, IL-1β, and TNFα elicit a broad and clinically relevant impairment of hepatic detoxification that is based on the simultaneous downregulation of many drug metabolizing enzymes and transporter genes. To address the question whether a common mechanism is involved we treated human primary hepatocytes with IL-6, the major mediator of the acute phase response in liver, and characterized acute phase and detoxification responses in quantitative gene expression and (phospho-)proteomics data sets. Selective inhibitors were used to disentangle the roles of JAK/STAT, MAPK, and PI3K signaling pathways. A prior knowledge-based fuzzy logic model comprising signal transduction and gene regulation was established and trained with perturbation-derived gene expression data from five hepatocyte donors. Our model suggests a greater role of MAPK/PI3K compared to JAK/STAT with the orphan nuclear receptor RXRα playing a central role in mediating transcriptional downregulation. Validation experiments revealed a striking similarity of RXRα gene silencing versus IL-6 induced negative gene regulation (rs = 0.79; P<0.0001). These results concur with RXRα functioning as obligatory heterodimerization partner for several nuclear receptors that regulate drug and lipid metabolism.
