Inflation and the steeplechase between economic activity variables: evidence for G7 countries
Authors: Baxa Jaromír , Plašil Miroslav , Vašíček Bořek 
Published: October 2016

AbstractA sharp increase in unemployment accompanied by a relatively muted response of inflation during the Great Recession and a consecutive inflationless recovery cast further doubts on the very existence of the Phillips curve as a systemic relation between real activity and inflation. With the aid of dynamic model averaging, this paper aims to highlight that this relation resurfaces if (i) inflationary pressures are captured by a richer set of real activity measures, and (ii) one accounts for the existence of a non-linear response of inflation to the driving variable. Based on data for the US and other G7 countries, our results show that the relation between economic activity and inflation is quite sturdy when one allows for more complex assessment of the former. We find that measures of economic activity describe inflation developments to a varying degree across time and space. This can blur the picture of inflation–real economy comovements in models where only a single variable of economic activity is considered. The output gap is often outperformed by unemployment-related variables. Our results also confirm a weakening of the inflation–activity relationship (i.e. a flattening of the Phillips curve) in the last decade that is robust both across activity measures and across countries.
A New Generalization of the P
1 Non-Conforming FEM to Higher Polynomial Degrees
Authors: Schedensack Mira 
Published: October 2016

Abstract
This paper generalizes the non-conforming FEM of Crouzeix and Raviart
and its fundamental projection property
by a novel mixed formulation for the
Poisson problem based on the Helmholtz decomposition.
The new formulation allows for ansatz spaces of arbitrary polynomial degree and
its discretization coincides with the mentioned non-conforming FEM for the
lowest polynomial degree.
The discretization directly approximates the gradient of the solution
instead of the solution itself.
Besides the a priori and medius analysis, this paper proves optimal
convergence rates for an adaptive algorithm for the new discretization.
These are also demonstrated in numerical experiments.
Furthermore, this paper focuses on extensions of this new scheme to
quadrilateral meshes, mixed FEMs, and three space dimensions.
Preparation of a poly(DMAEMA-co-HEMA) self-supporting microfiltration membrane with high anionic permselectivity by electrospinning
Authors: Ni Henmei , Yang Yadong , Chen Yixuan , Liu Junxiu , Zhang Lijuan , Wu Min 
Published: October 2016

Abstract
A cross-linked microfibrous anion exchange membrane with high ion permselectivity and robust mechanical properties was fabricated by electrospinning. Copolymer, poly N,N-dimethylaminoethyl methacrylate (DMAEMA)-co-2-hydroxyethyl methacrylate (HEMA), was selected as the electrospun material. Fourier transform infrared (FTIR) spectroscopy, 1HNMR and scanning electron microscopy (SEM) were employed to characterize the copolymer and microfibrous mat. The electrospinning optimal parameters were determined by orthogonal experiments. Formaldehyde vapor was applied to crosslink the mat. It was observed that the water sorption decreased from 75.7% to 30.4% as the crosslinking time increased from 20 h to 32 h. The robust mat with the high tensile strength of 4.62 MPa and 50% elongation at break was obtained at 24 h. The ion permeability of NO3
−, Cl−, SO4
2− were 94, 91 and 87%.

Obstacles to emancipation of Roma women
Authors: Kajanová Alena , Mrhálek Tomáš , Lidová Lenka 
Published: October 2016

Abstract
The article describes the obstacles to the emancipation of Roma women in the family and Czech society. The theoretical side deals with the recent changes in gender roles in the Roma family, changes in the position of Roma women and their discrimination as well as the concept of emancipation. The article aims to describe the obstacles a Roma woman must overcome in the course of emancipation. The data are based on qualitative socio-ethnographic research conducted through narrative interviews with 30 women of different ages and classes who identify as Roma and live in three Czech regional capitals. The research sample was compiled using the snowball method. The data collected in the field research were analyzed in Atlas.ti using anchored theory. We identified five main obstacles to the emancipation of Roma woman. They include obstacles emanating from the family and the majority society as well as obstacles caused by the hegemony of masculinity and those emanating from the woman. By gaining an understanding of relations in Roma families, the situation regarding the emancipation of Roma women and the associated barriers may help those who come into daily contact with the Roma minority to take appropriate actions and apply the right interventions.
Nachwirkungen des Nationalsozialismus. Mechanismen der Schuldübertragung auf die Kinder der Täter und ihre erinnerungskulturellen Funktionen in Martin Walsers Drama Der Schwarze Schwan
Authors: Welsh Caroline 
Published: October 2016

AbstractThe paper analyses the link between the National Socialist Euthanasia-Programme, the Holocaust and the effect of these mass murders on the children of perpetrators as depicted in Martin Walser’s Der schwarze Schwan. First performed during the Frankfurter Auschwitz-Process, the drama prefigures later psychoanalytical theories on the transmission of guilt to the second generation. A close reading of the drama reveals the importance of childhood memories and contrasts them with Walser’s statements on the effect of the holocaust on his childhood memories.
Die deutsche Geschichtswissenschaft und die Moderne
Authors: Dipper Christof 
Published: October 2016

AbstractFor decades German historiography was rather reluctant to develop its own concept of modernity. It started to do so only once people began to feel ›post-modern‹, i.e., once people felt that modernity had come to an end. This article presents six versions of an historical theory of modernity, the last theory being the only one sufficiently complete and complex to meet the task.
Postmoderne. Bezeichnung eines Transformationsprozesses innerhalb der ästhetischen Moderne
Authors: von Petersdorff Dirk 
Published: October 2016

AbstractAlthough semantically misleading, the persistent term »postmodernity« might function as a label that deserves further scrutiny. Within the arts the assumption of a simple convergence of historical process and aesthetic structure has been questioned during the last thirty years. This leads to a pluralism of aesthetic programs that can no longer be labeled as either historically legitimate or illegitimate.
Die Aufnahme von Ilse Aichingers Die größere Hoffnung im niederländischen Sprachraum
Authors: Andringa Els 
Published: October 2016

AbstractThis article sketches the reception of Die größere Hoffnung in the Dutch language area from the first reviews in the early fifties up to the present day. The focus is on Frank Schuitemaker’s translation which appeared in 1981 together with an introduction to Aichinger’s life and work. A few examples show that the translator based his choices on a careful interpretation and thorough knowledge of Aichinger’s work. Nevertheless the reception remained modest, despite evidence of increased interest after the second edition appeared in 1987, the year in which Aichinger received the Europalia price.
Das Recht zu Atmen
Authors: Holm Isak Winkel 
Published: October 2016

Abstract:In Dostoevsky, the question of justice is not only posed as a legal or moral question but also, on a more fundamental level, as a question of a human being’s right to live, its raison d’être. This article will interpret the central notion of justice in Dostoevsky in the conceptual framework of the theory of recognition as it is put forward in Hegel’s early Jenaer Realphilosophie.

PI Passivity-Based Control for Maximum Power Extraction of a Wind Energy System with Guaranteed Stability Properties
Authors: Cisneros Rafael , Gao Rui , Ortega Romeo , Husain Iqbal 
Published: October 2016

Abstract
The present paper proposes a maximum power extraction control for a wind system consisting of a turbine, a permanent magnet synchronous generator, a rectifier, a load and one constant voltage source, which is used to form the DC bus. We propose a linear PI controller, based on passivity, whose stability is guaranteed under practically reasonable assumptions. PI structures are widely accepted in practice as they are easier to tune and simpler than other existing model-based methods. Real switching based simulations have been performed to assess the performance of the proposed controller.
Prevalence of medically treated children with ADHD and type 1 diabetes in Germany – Analysis of two representative databases
Authors: Kapellen Thomas M. , Reimann Rebecca , Kiess Wieland , Kostev Karel 
Published: October 2016

AbstractBackground:The aim of this study was to analyze the prevalence of attention deficit hyperactivity disorder (ADHD) in children and adolescents with type 1 diabetes mellitus (T1DM) in Germany.Methods:Two different representative German databases – IMS®-Disease Analyzer, a database that includes diagnoses as well as other information, and IMS®-LRx, a database that documents prescriptions – were used to conduct a retrospective analysis. We searched the LRx database for patients who received both insulin and ADHD-specific medication.Results:In 2014, 677,587 children and adolescents aged 0–18 years were treated by a pediatrician and documented in the Disease Analyzer database. Of these patients, 16,833 received the International Statistical Classification of Diseases and Related Health Problems (ICD-10) diagnosis of ADHD (2.5%) and 3668 patients were treated for T1DM (0.1%). Of these 3668 patients, a total of 153 children were also diagnosed with ADHD (4.2%; p<0.05). In the LRx database, the overall prevalence of children in Germany who received both drugs for the treatment of ADHD and insulin in 2014 amounted to 2.9%. Diagnosis of ADHD is 2.4–3.3 times more frequent in boys than in girls. The highest prevalence was seen in the age group of 12–15 years (3.5%) and the lowest in the age group of 6–11 years (2.5%).Conclusions:Children with diabetes suffer from ADHD significantly more frequently than children without diabetes. The prevalence of medically treated children with ADHD and diabetes is similar to that documented in a recent report by the Barmer GEK health insurance body. However, it is possible that children with T1DM are much more frequently seen by medical care providers and are thus more likely to be evaluated and receive an appropriate diagnosis.

Published: October 2016

AbstractWe demonstrated two methods of increasing the bandwidth of a broadband light source based on amplified spontaneous emission in thulium-doped fibres. Firstly, we have shown by means of a comprehensive numerical model that the full-width at half maximum of the thulium-doped fibre based broadband source can be more than doubled by using specially tailored spectral filter placed in front of the mirror in a double-pass configuration of the amplified spontaneous emission source. The broadening can be achieved with only a small expense of the output power. Secondly, we report results of the experimental thulium-doped fibre broadband source, including fibre characteristics and performance of the thulium-doped fibre in a ring laser setup. The spectrum broadening was achieved by balancing the backward amplified spontaneous emission with back-reflected forward emission.
Hydrolysis of chitin and chitosan in low temperature electron-beam plasma
Authors: Vasilieva Tatiana , Lopatin Sergey , Varlamov Valery , Miasnikov Vladimir , Hein Aung Myat , Vasiliev Michael 
Published: October 2016

Abstract
Hydrolysis of natural chitin and chitosans was performed in the electron beam plasma (EBP) of oxygen, by means of specially designed electron beam plasmachemical reactor (EBPR). Low molecular water-soluble chitin oligosaccharides with weight-average molecular mass 800–2000 Da and polydispersion index 1.5–2.5 were produced due to action of active oxygen species formed in the EBP. By optimizing the treatment conditions the 95% yield of chitin oligosaccharides was obtained after 2 min whereas the conventional chemical hydrolysis usually takes several days. The studies of the antimicrobial activity of low molecular products formed due to EBP-stimulated degradation showed that they inhibit the multiplication of various mycelial and yeast-like fungi. The technique involved is likely to be promising for the production of bioactive low molecular chitin oligosaccharides and the EBP-stimulated hydrolysis appears to be competitive with technologies conventionally used in the industry.

Abstract
Synthesis via ozone precipitation reaction was used to obtain manganese dioxide (OMD) and it was probed as an adsorbent for zinc ions. Adsorption was followed along shaking time and increasing ratio [NO
3
−] / [Zn2+], and isotherms were obtained at different pH values and in the presence of several anions (chloride, nitrate, sulphate, and acetate). It was found that adsorption equilibrium is fast and follows the pseudo-second order model (qe = 34 ±1 mg/g and K = 0.07 ±0.01 g/mg h). Isotherms were fitted to Langmuir, Freundlich, and Langmuir-Freundlich models, and the best fitting was found with the last one. The process is dependent on pH and the efficiency increases from pH 1 to 4. The ratio [NO
3
−] / [Zn2+] up to 3 does not seem to change the behaviour of the process. Regarding the anions, the efficiency of Zn(II) adsorption occurs according to: acetate > nitrate and sulphate > chloride. Manganese oxide obtained via ozonization is an excellent adsorbent for zinc ions.

Published: October 2016

Abstract
Halloysite nanotubes (HNTs) reinforced epoxy composites with improved mechanical properties were prepared. The prepared HNTs reinforced epoxy composites demonstrated improved mechanical properties especially the fracture toughness and flexural strength. The flexural modulus of nanocomposite with 6% mHNTs loading was 11.8% higher than that of neat epoxy resin. In addition, the nanocomposites showed improved dimensional stability. The prepared halloysite reinforced epoxy composites were characterized by thermal gravimetric analysis (TGA). The improved properties are attributed to the unique characteristics of HNTs, uniform dispersion of reinforcement and interfacial coupling.
Preparation, characterization and application of superparamagnetic iron oxide nanoparticles modified with natural polymers for removal of 60Co-radionuclides from aqueous solution
Authors: Sharaf El-Deen Gehan E. , Imam Neama G. , Ayoub Refaat R. 
Published: October 2016

Abstract
Superparamagnetic iron oxide nanoparticles (IO-MNPs) coated with natural polymers, starch (IO-S MNPs) and dextrin (IO-D MNPs), were synthesized by modified co-precipitation method. IO and hybrid-IO-MNPs were characterized by XRD, SEM, HRTEM, FT-IR spectroscopy, vibrating sample magnetometer (VSM) and zeta potential (ZP). IO-S MNPs and IO-D MNPs have IO core-shell structure with core of 10.8 nm and 13.8 nm and shell of 7.5 nm and 5.9 nm, respectively. The efficiency of the hybrid IO-MNPs for sorption of 60Co(II)-radionuclides from aqueous solution was investigated under varying experimental conditions. Kinetic data were described well by pseudo-second-order mode, sorption isotherms were fitted quite with Freundlich model with maximum adsorption capacity 36.89 (mmol·g−1)/(L·mmol−1)n for IO-S MNPs and 24.9 (mmol·g−1)/(L·mmol−1)n for IO-D MNPs. Sorption of 60Co-radionuclides by IO-S MNPs was suppressed with salinity and most of the adsorbed 60Co onto IO-S MNPs could be remove with 0.1 M HCl solution. IO-S MNPs exhibits superparamagnetic properties, easier separation according to higher saturation magnetization (47 emu/g) and better adsorption for 60Co-radionuclides than IO-D MNPs.

Published: October 2016

AbstractIn situTiB2/Al-4.5Cu composites with different TiB2particle amounts were fabricated by the salt-metal reaction technique. The effects ofin situTiB2on the microstructure and mechanical properties of Al-4.5Cu alloy were studied in this paper. The results showed thatin situTiB2particles had significant effect on refining grain size and improving mechanical properties of as-cast Al-4.5Cu alloy. With the amounts of TiB2particles increasing, the yield strength and ultimate tensile strength were improved, while the elongation reduced. The strengthening mechanisms of thein situparticle-reinforcing Al matrix composites were discussed, and the yield strength was predicted accurately by accounting for the three strengthening mechanisms and particle distribution.

Authors: Kumar Shiv Ranjan , Patnaik Amar , Bhat I.K. 
Published: October 2016

Abstract
The aims of the present study were to develop a dental composite filled with silanized nanoalumina and then to investigate the effect of nanoalumina filler on the two-body and three-body wear behavior under distilled water and food slurry medium, respectively. The dental composites were fabricated by adding silane treated nanoalumina filler particle in the weight percentage of (0–3 wt.%) to the matrix of BisGMA, TEGDMA, CQ and EDMAB. Two-body and three-body wear tests were performed in dental wear simulator machine with varying parameters such as normal load, chewing speed and chamber temperature in such a way as to simulate mastication process. Taguchi’s orthogonal array (L16) design, steady state condition and ANOVA were applied to evaluate the optimum parameter for minimum wear and effect of each parameter on the wear performance of dental composites. The finding of the result indicated that mean volumetric wear rate of dental composite in distilled water (i.e. two-body abrasion) was 33.23% more than that of the same composite in food slurry condition (i.e. three-body abrasion).
„I apologize to Giorgio Chiellini and the entire football family.“ / Zur Rolle Sozialer Medien in der Krisenkommunikation - dargestellt an Beispielen im Kontext der Fußball-WM 2014 in Brasilien
Authors: Burk Verena , Grimmer Christoph G 
Published: October 2016

Zusammenfassung
Im Beitrag wird untersucht, ob und mit welchen Strategien Athleten sowie Sportorganisationen in Krisen des Sports Soziale Medien in ihrer Krisenkommunikation verwenden. Ausgehend von der Theorie der situationsbezogenen Krisenkommunikation (SCCT) nach Coombs (1995; 2010), der bei verschiedenen Krisentypen spezifische Kommunikationsstrategien empfiehlt, werden Facebook-Posts und Tweets/Retweets von Spielern und Verbänden bei zwei ausgewählten Krisen während der Fußball-WM 2014 (Ausscheiden Spaniens in der Vorrunde; ‚Suárez-Biss‘) qualitativ analysiert. Den Ergebnissen zufolge werden die Möglichkeiten Sozialer Medien nicht bzw. nur unzureichend genutzt. In beiden Fällen findet keine zeitnahe Krisenkommunikation statt. Bei der Spanien-Krise schätzen die Beteiligten die Krisenschuldzuschreibung durch die Öffentlichkeit und den damit verbundenen Reputationsschaden höher ein als notwendig; im zweiten Fall wird ein individuelles Fehlverhalten trotz vorliegender Krisenhistorie dagegen unterschätzt.

Abstract

Introduction
Alpha-thalassemia (α-thal) is one of the most common diseases in the world, and is more common in the Mediterranean countries, the Middle East, Southeast Asia, and Africa. The aim of this study was to determine the prevalence and genotypes of α-thal in high school students in Adıyaman province, Southeast Turkey.

Methods
In this study, a total of 289 people were screened for α-thal mutations by multiplex gap-PCR and ARMS.

Results
α-thal mutation frequency was determined to be 13.15%. Five different mutations were identified and the most common mutation was found to be −3.7 deletions with a frequency of 11.07%. We identified two heterozygous alpha hemoglobin variants. We described the second case of heterozygote Hb Fontainebleau of Turkish origin. Here, we also reported another heterozygote hemoglobin variant, Hb Q-Iran, previously reported in a few cases in another part of Turkey.

Discussion and conclusion
This study covers the frequency of α-thal disease, and the molecular analysis is the first study in the Southeastern Anatolia Region of Turkey. The prevalence of the α-thal trait is low in Adıyaman Province, compared to the other cities of Turkey.
