Ist umweltbezogener Gesundheitsschutz noch nachgefragt?
Authors: Wiesmüller Gerhard A. , Hornberg Claudia 
Published: October 2014

Einleitung
Umweltbezogener Gesundheitsschutz bedeutet, sowohl potenziell gesundheitsgefährdende schädliche Umwelteinflüsse zu erkennen, zu bewerten und entsprechend zu verhindern als auch begünstigende Umwelteinflüsse als Gesundheitsressource zu erkennen und zu fördern. Diese Aufgabe obliegt im Regelfall den unteren Gesundheitsbehörden der Landkreise und kreisfreien Städte. Um diese Aufgaben mit hoher Qualität (weiterhin) erfüllen zu können, bedarf es im öffentlichen Gesundheitsdienst der Kontinuität an qualifizierten Mitarbeiter/Mitarbeiterinnen sowie deren regelmäßigen Fortbildung. Die Vielfalt der Aufgabenfelder des umweltbezogenen Gesundheitsschutzes unterstreicht dessen Stellenwert an der Schnittstelle zwischen Humanmedizin, Public Health und Umweltwissenschaften als eine zentrale Einrichtung zum Wohle und zum Schutz der Bevölkerungsgesundheit in Deutschland.

Published: October 2014

AbstractWe present wall-modelled large-eddy simulations (WLES) of oblique shock waves interacting with the turbulent boundary layers (TBLs) (nominal$\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}\delta _{99}=5.4\ \mathrm{mm}$and${\mathit{Re}}_{\theta }\approx 1.4\times 10^4$) developed inside a duct with an almost-square cross-section ($45\ \mathrm{mm}\times 47.5\ \mathrm{mm}$) to investigate three-dimensional effects imposed by the lateral confinement of the flow. Three increasing strengths of the incident shock are considered, for a constant Mach number of the incoming air stream$M\approx 2$, by varying the height (1.1, 3 and 5 mm) of a compression wedge located at a constant streamwise location that spans the top wall of the duct at a 20° angle. Simulation results are first validated with particle image velocimetry (PIV) experimental data obtained at several vertical planes (one near the centre of the duct and three near one of the sidewalls) for the 1.1 and 3 mm-high wedge cases. The instantaneous and time-averaged structure of the flow for the stronger-interaction case (5 mm-high wedge), which shows mean flow reversal, is then investigated. Additional spanwise-periodic simulations are performed to elucidate the influence of the sidewalls, and it is found that the structure and location of the shock system, as well as the size of the separation bubble, are significantly modified by the lateral confinement. A Mach stem at the first reflected interaction is present in the simulation with sidewalls, whereas a regular shock intersection results for the spanwise-periodic case. Low-frequency unsteadiness is observed in all interactions, being stronger for the secondary shock reflections of the shock train developed inside the duct. The downstream evolution of secondary turbulent flows developed near the corners of the duct as they traverse the shock system is also studied.
Transnational Political Cosmology: A Central Mediterranean Example
Authors: Ben-Yehoyada Naor 
Published: October 2014

AbstractThis paper examines the workings of kinship and marriage idioms in transnational political imaginary in the central Mediterranean to challenge current academic reliance on the notion of fraternity as the symbolic building block of both national and global political relations. Since the 1960s, the Sicilian town of Mazara del Vallo and its fishing fleet have become entwined in intensifying interactions with Tunisia and the wider Maghreb. These interactions—specifically the Tunisian-Italian “Fish War” and construction of a trans-Mediterranean natural gas pipeline between North Africa and Europe—rejuvenated the old geopolitical imagination of the Mediterranean and helped produce the central Mediterranean as a spatio-temporal field of political action. Italians and Tunisians perceived each other as related, and staged the trans-Mediterranean infrastructural project as a sort of European-African (cross-cousin) marriage. I begin by examining the tensions between two central kinship idioms—fraternity and cousinage—in current understandings of transnational relations. I then discuss the growing prevalence of a transnational political cosmology of affinity across difference over that of shared descent and sameness that characterize national alignments. I conclude by examining how Tunisians and Sicilians in Mazara today cast each other in roles deriving from segmentary schemes they share, but on the content of which they disagree. By applying concepts associated with kinship and marriage studies to recent Mediterranean history, I show how segmentation, a concept anthropologists abandoned when they crossed the Mediterranean on their way into Europe, can help us understand transnational politics.
Sounding the Latin Transatlantic: Music, Integration, and Ambivalent Ethnogenesis in Spain
Authors: Tucker Joshua 
Published: October 2014

AbstractThis article uses commentary on and consumption of popular music as a lens to explore how Peruvian immigrants in Spain experience new notions of belonging and alterity as they tack between official Spanish discourses about difference and otherness and distinct notions of unity and sameness that circulate within the country's wider Latin American community. I examine the uneven, tentative emergence of a local Latino identity, and how this formation compares to the tenets that accrue to the formation found in the United States. I explain how the naturalization of this new and alien way of organizing national difference, in concert with native Spanish ideas about European modernity and the need to suppress ethnicitytout court, tends to marginalize distinctive experiences valued by indigenous and mestizo Peruvians from the country's Andean region. I show how they evade the homogenizing tendencies of Latino discourse, bypass native Spanish opposition to the very notion of deep difference, and seek out spaces for asserting difference. Considered also are challenges faced by a country that has undergone rapid and recent multicultural change, even as it seeks to become part of a European project that citizens view widely as an effort to transcend divisive particularity.
Progress and Backwardness in Book Accumulation: Bancroft, Basadre, and Their Libraries
Authors: Salvatore Ricardo D. 
Published: October 2014

AbstractThe essay examines the conditions of book accumulation in two places in the world economy, California and Peru, through the narratives left by book collector Hubert Bancroft and librarian and historian Jorge Basadre. A reading of these reveals the complex interrelations between socioeconomic development and cultural accumulation. In California, Bancroft turned his fortune accumulated through business into a unique book collection and this, in turn, was placed at the service of a “factory of history” that produced a multivolume “History of the Pacific States of North America.” In the Peruvian case, after a fire destroyed most of the collections of the National Library of Lima, historian Basadre directed an effort of reconstruction that led him to reflect upon the state's neglect of cultural patrimony, popular disdain for high culture, and Peru's long tradition of exporting books and documents to foreign collectors and libraries. Basadre's reflections speak of the position of a peripheral intellectual within a context of underdevelopment. I examine the centripetal logic of book accumulation and call for further engagement with this neglected side of cultural history.
Adaptivity in high-performance embedded systems: a reactive control model for reliable and flexible design
Authors: Yu Huafeng , Gamatié Abdoulaye , Rutten Éric , Dekeyser Jean-Luc 
Published: October 2014

AbstractSystem adaptivity is increasingly demanded in high-performance embedded systems, particularly in multimedia system-on-chip (SoC), owing to growing quality-of-service requirements. This paper presents a reactive control model that has been introduced in Gaspard, our framework dedicated to SoC hardware/software co-design. This model aims at expressing adaptivity as well as reconfigurability in systems performing data-intensive computations. It is generic enough to be used for description in the different parts of an embedded system, for example, specification of how different data-intensive algorithms can be chosen according to some computation modes at the functional level; and expression of how hardware components can be selected via the usage of a library of intellectual properties according to execution performances. The transformation of this model toward synchronous languages is also presented, in order to allow an automatic code generation usable for formal verification, based on techniques such as model checking and controller synthesis, as illustrated in the paper. This work, based on Model-Driven Engineering and the standard UML MARTE profile, has been implemented in Gaspard.
Taxonomy of reputation assessment in peer-to-peer systems and analysis of their data retrieval
Authors: Azzedin Farag 
Published: October 2014

AbstractThe need for reputation assessment is particularly strong in peer-to-peer (P2P) systems because the peers’ personal site autonomy is amplified by the inherent technological decentralization of the environment. However, the decentralization notion makes the problem of designing a P2P-based reputation assessment substantially harder in P2P networks than in centralized settings. Existing reputation systems tackle the reputation assessment process in anad hocmanner. There is no systematic and coherent way to derive measures and analyze the current reputation systems. In this paper, we propose a reputation assessment process and use it to classify the existing reputation systems. Simulation experiments are conducted and focused on the different methods in selecting the recommendation sources and collecting the recommendations. These two phases can contribute significantly to the overall performance owing to precision, recall, and communication cost.
Conceptual modeling for knowledge management to support agile software development
Authors: Amritesh  , Misra Subhas C. 
Published: October 2014

AbstractAgile software development (ASD) has emerged as a result of consolidated values proposed under the lightweight methods of software engineering. Despite bearing some criticisms, the initial deployment and results observed in the practice environment represents its increasing domination over the traditional software development practices. Any ASD method, in particular, requires knowledge-intensive practices and typically employs multi-disciplinary expert team working extended periods of time for weeks on a nearly continuous basis. A huge amount of tacit knowledge creation and exchange happens in the entire process over the project lifecycle, which attracts the attention of research in the domain of knowledge management (KM). In this paper, first, we have mapped the agile values and agile principles, and in its support, we have argued upon and the need for integrated KM infrastructure and proposed a KM model that can be employed within the organization. We have also developed a conceptual framework for knowledge sharing and learning for the individual practitioners for the sustainability of agile team. We attempt to create an organizational learning framework for knowledge creation and exchange among the involved entities in a collaborative practice environment.
Boundedness and stabilization in a multi-dimensional chemotaxis—haptotaxis model
Authors: Tao Youshan , Winkler Michael 
Published: October 2014

This paper deals with the coupled chemotaxis-haptotaxis model of cancer invasion given bywhereχ, ξandμare positive parameters andΩ ⊂ ℝn(n≥ 1) is a bounded domain with smooth boundary. Under zero-flux boundary conditions, it is shown that, for anyμ>χand any sufficiently smooth initial data (u0,w0) satisfyingu0≥ 0 andw0> 0, the associated initial–boundary-value problem possesses a unique global smooth solution that is uniformly bounded. Moreover, we analyse the stability and attractivity properties of the non-trivial homogeneous equilibrium (u, v, w) ≡ (1,1, 0) and establish a quantitative result relating the domain of attraction of this steady state to the size ofμ. In particular, this will imply that wheneveru0> 0 and 0 <w0< 1 inthere exists a positive constantμ* depending only onχ, ξ, Ω, u0andw0such that for anyμ<μ* the above global solution (u, v, w) approaches the spatially uniform state (1, 1, 0) as time goes to infinity.
Multiple solutions for a free boundary problem arising in plasma physics
Authors: Liu Zhongyuan 
Published: October 2014

In this paper we study the existence of solutions for a free boundary problem arising in the study of the equilibrium of a plasma confined in a tokamak:where p > 2, Ω is a bounded domain in ℝ2, n is the outward unit normal of ∂Ω, α is an unprescribed constant and I is a given positive constant. The set Ω+ = {x ∊ Ω: u(x) > 0} is called a plasma set. Under the condition that the homology of Ω is non-trivial, we show that for any given integer k ≥ 1 there exists λk > 0 such that for λ > λk the problem above has a solution with a plasma set consisting of k components.
BEYOND THE OTHER SHORE: GERMAN INTELLECTUALS IN THE UNITED STATES
Authors: DERMAN JOSHUA 
Published: October 2014

For over half a century, the American transformation of German philosophy and social thought has been a major theme of modern intellectual history. The main protagonists of this “cultural migration,” as the story traditionally has been told, were German-speaking scholars and writers who, fleeing Hitler's Europe, brought their erudition and indigenous methodologies to American shores. But beyond this beachhead lies a vast and unfamiliar terrain for the historian. What became of German texts and concepts as they traveled further inland? Who transported them—and for what ends? InThe Closing of the American Mind, the philosopher Allan Bloom marveled at the ways in which nonacademic Americans had become complicit in the dissemination of German thought: “What an extraordinary thing it is that high-class talk from what was the peak of Western intellectual life, in Germany, has become as natural as chewing gum on American streets.” It was an extraordinary thing, but not a good one, as far as Bloom was concerned:We are like the millionaire inThe Ghost (Geist) Goes Westwho brings a castle from brooding Scotland to sunny Florida and adds canals and gondolas for “local color.” We chose a system of thought that, like some wines, does not travel; we chose a way of looking at things that could never be ours and had as its starting point dislike of us and our goals. The United States was held to be a nonculture, a collection of castoffs from real cultures, seeking only comfortable self-preservation in a regime dedicated to superficial cosmopolitanism in thought and deed. Our desire for the German things was proof we could not understand them.
Slot dipole antenna with single‐ and dual‐band tuning characteristic
Authors: Idris I.H. , Hamid M.R. , Jamaluddin M.H. , Rahim M.K.A. , Kelly J. 
Published: October 2014

A slot dipole antenna with a reconfigurable operating frequency is presented. The antenna comprises two pairs of slot arms. Each arm incorporates a number of varactor diodes. The antenna is capable of operating in single‐band or dual‐band mode. In each case, the location of these bands can be altered by varying the voltage applied to the varactor diodes. The antenna can be tuned over a wide frequency range, namely 1.5–4.5 GHz (i.e. a ratio of 3:1). The antenna is potentially useful for cognitive radio application, particularly in a small base station or access point terminal.
Bifunctional ectodermal stem cells around the nail display dual fate homeostasis and adaptive wounding response toward nail regeneration
Authors: Leung Yvonne , Kandyba Eve , Chen Yi-Bu , Ruffins Seth , Chuong Cheng-Ming , Kobielak Krzysztof 
Published: October 2014

Significance
Skin appendages including hair follicles, sweat glands, and nails offer a source of regenerative support following injury. Here, we focus on the regenerative potential of the peri-nail region and reveal a population of K15-positive, label retaining cells (LRCs) within the nail proximal fold with self-renewal capabilities. Physiologically, these cells display bifunctional stem cell qualities and contribute to both the nail structure and peri-nail epidermis long term; however, upon injury, the homeostatic balance is tilted toward nail regeneration. Molecularly, reduced bone morphogenetic protein signaling tilts nail keratinocytes toward an epidermal fate. Collectively, we demonstrate the plasticity of these stem cells: bifunctional under normal homeostasis, but adaptive in response to wounding. Such principles may exist in the interface between other ectodermal organs and skin.

Published: October 2014

ABSTRACTObjectives:Adalimumab, a humanised anti‐tumour necrosis factor antibody, is an effective treatment in adult patients with refractory Crohn disease (CD). The available literature on its efficacy in children remains limited. We aimed to evaluate the real‐world efficacy in paediatric patients with CD and compare the efficacy between infliximab (IFX) nonresponders and patients who lost response to IFX.Methods:All Dutch patients with CD receiving adalimumab before the age of 18 years after previous IFX therapy were identified. We analysed longitudinal disease activity, assessed by the mathematically weighted Pediatric Crohn's Disease Activity Index (wPCDAI) or the physician global assessment (PGA), and adverse events (AEs).Results:Fifty‐three patients with CD were included. Twelve patients received monotherapy and the others received combination treatment with thiopurines (n = 21), methotrexate (n = 11), steroids (n = 7), or exclusive enteral nutrition (n = 2). Median follow‐up was 12 months (interquartile range 5–23). Remission was reached in 34 patients (64%, wPCDAI < 12.5 or PGA = 0) after a median of 3.3 months, and maintained by 50% for 2 years. Eleven patients (21%) reached response but not remission (decrease in wPCDAI ≥ 17.5 or decrease in PGA). Eighteen patients (34%) failed adalimumab treatment because of nonresponse (n = 4), lost response (n = 11), or AEs (n = 3). More IFX nonresponders failed adalimumab treatment than patients who lost response to IFX (2/3 vs 8/34, hazard ratio 18.8, 95% confidence interval 1.1–303.6). Only 1 patient encountered a serious AE, a severe but nonfatal infection.Conclusions:In clinical practice, adalimumab induces remission in two‐thirds of children with IFX refractory CD.

Authors: D. Carnegie Garry 
Published: October 2014

Purpose– The purpose of this paper is to outline some personal reflections, based on recent published accounting history research and methodological contributions, on the state of the art and future directions in interdisciplinary research on accounting's past.Design/methodology/approach– An essay focusing on recent developments in the accounting history specialisation and outlining some possible future research developments.Findings– The paper points to the growing literature in the accounting history specialisation; the conduct of historical accounting research across an array of institutions, including business, social and religious institutions; the diversity of theoretical perspectives which have been applied during the past 15-20 years, essentially on the premise of accounting as social practice, and the prospects of theoretically-informed investigations continuing to offer the greatest potential insight into both accounting's present and future. Reflections rendered on possible future directions of historical accounting research may provide some motivation for future research or at least stimulate some discussion and debate on the subject.Research limitations/implications– The analysis and critique represents the author's perspectives as a longstanding academic in the field.Originality/value– The paper may assist in generating some new ideas, topics and approaches for future historical accounting research in any given country or region and may even stimulate “comparative international accounting history” (CIAH) studies in different locations around the globe.
Addressing directions in interdisciplinary accounting research
Authors: D. Parker Lee , Guthrie James 
Published: October 2014

Purpose
– The purpose of this paper is to address and critique the current state and trajectory of the interdisciplinary accounting movement.

Design/methodology/approach
– An interdisciplinary literature sourced analysis and critique of the movement's positioning and trajectory.

Findings
– It observes the creeping currency of the financial economics-based accounting research tradition, with its attendant limitations in scope and policy/practice relevance of its subject matter and findings. The paper reveals the persistent growth and development of an interdisciplinary accounting community despite the pressures of careerist research score-based goal displacement produced by government and university performance measurement systems.

Originality/value
– The interdisciplinary movement is seen as offering issues focused and innovation-driven research that aims to engage with the complexities of the organisational and institutional actors’ worlds. This remit remains essential to the challenge of the accounting academy's pursuit of issues of societal significance.
