Krankenhausinfektionen
Authors: Martiny Heike , Popp Walter 
Published: July 2014

Einleitung
Nosokomiale Infektionen (NI) sind von Risikofaktoren abhängig, die sowohl in Bezug auf den Patienten selber bestehen als auch hinsichtlich weiterer Einflüsse während seiner Behandlung. Aufgrund verschiedener Daten errechnet für Deutschland bei 1,3 Mio NI eine Zahl von 30.000 Toten. NI verursachen Kosten, die 10.000 € pro Patient betragen können. NI stellen in Deutschland sowohl eines der größten gesundheitspolitischen als auch der gesamtgesellschaftlichen Probleme dar.
Influenzaimpfung – für Risikogruppen besonders wichtig
Authors: Wicker Sabine 
Published: July 2014

Einleitung
Jahr für Jahr führen Influenzainfektionen zu Krankenhauseinweisungen, Todesfällen und Fehltagen in der Schule und am Arbeitsplatz. Influenza ist jedoch eine impfpräventable Erkrankung. Maßnahmen zur Erhöhung der Impfquoten bei den Risikogruppen und beim medizinischen Personal sollten ein wichtiges gesundheitspolitisches Ziel darstellen.
Revising Lehár’sRastelbinderfor the Reich
Authors: Petersen Ulrike 
Published: July 2014

AbstractOperetta held an ambiguous position within Nazi German entertainment culture: while suitably diverting and escapist, many of the most successful hits had Jewish authors and were thus increasingly avoided by theatre directors. To replenish the Reich’s performable repertory, Goebbels founded the ‘Reichsstelle für Musikbearbeitungen’, whose revisions of classical works including Handel’s oratorios and Mozart’s Da Ponte operas have been widely discussed. This article focuses on one of the institution’s many operetta commissions, Viennese satirist Rudolf Weys’s unfinished 1944 version of Franz Lehár’sDer Rastelbinder(1902), a box office success that featured an itinerant Jewish peddler as the central character. Weys’s revisions as well as his own story show that this kind of Reichsstelle commission could be a lifeline for artists who could not afford to attract attention or leave the Reich.
Evaluating Angular Ion Current Density for Atomically Defined Nanotips
Authors: Urban Radovan , Wolkow Robert A. , Pitters Jason L. 
Published: July 2014

AbstractIn this paper we investigate methods to characterize angular current density from atomically defined gas field ion sources. We show that the ion beam emitted from a single apex atom is described by a two-dimensional Gaussian profile. Owing to the Gaussian shape of the beam and the requirement to collect the majority of the ion current, fixed apertures have inhomogeneous illumination. Therefore, angular current density measurements through a fixed aperture record averaged angular current density. This makes comparison of data difficult as averaged angular current density depends on aperture size. For the same reasons, voltage normalization cannot be performed for fixed aperture measurements except for aperture sizes that are infinitely small. Consistent determination of angular current density and voltage normalization, however, can be achieved if the beam diameter as well as total ion current are known. In cases where beam profile cannot be directly imaged with a field ion microscope, the beam profile could be extracted from measurements taken at multiple acceleration voltages and/or with multiple aperture sizes.

AbstractSexual harassment is among the most serious forms of gender violence, and what all violent acts have in common are the many myths associated with them. Three studies were conducted to adapt a Spanish version of the Illinois Sexual Harassment Myth Acceptance (ISHMA) scale, which assesses myths about sexual harassment. The first study aimed to, for the first time, present psychometric data on the Spanish version of the ISHMA. The participants were 339 college students. After adapting the items and measuring their content validity, we examined the test’s dimensional structure, statistically analyzed the items, and determined the instrument’s reliability (α = .91 for the total scale and between .77 and .84 for the different dimensions). Study 2 involved 326 adult participants from the general population and its objective was to evaluate the scale’s dimensional structure through confirmatory factor analysis (χ2143 = 244.860, p < .001; GFI = .952; CFI = .958; RMSEA = .034 [.026 – .041]). The third study was conducted in order to measure convergent validity in both students and adults from the general population. Differences by gender were found in all dimensions being the females’ means higher than males (Cohen´s d between .38 and .62). Our findings suggest the Spanish version of the ISHMA is a useful instrument to study myths about sexual harassment.
Grammatical Comprehension in Spanish-Speaking Children with Specific Language Impairment (SLI)

Published: July 2014

AbstractThe Grammatical Structures Comprehension Test (CEG) was used to analyze grammatical comprehension problems in native Spanish-speaking children with Specific Language Impairment (SLI). The test is divided into 20 blocks containing the most common grammatical structures in Spanish. Our objective was to establish whether the CEG was sensitive in detecting these problems and whether there were differential patterns in grammatical comprehension between children with SLI (14 participants) and two control groups: a chronological control group (CC) with 14 participants and a linguistic control group (LC) also with 14 participants. We found significant differences between the SLI group and the chronological control participants (Box’s M = 63.080,F= 1, 159,p= .238), with a correct classification rate of 85.7 % in the discriminant function analysis. These differences did not occur in all the blocks, in which we identified a range of different performance patterns that varied according to the structures being analyzed. This work helps to clarify certain questions about grammatical comprehension in children with SLI and contributes to the debate on delay vs. “delay within the delay”.
Measuring Affect at Work Based on the Valence and Arousal Circumplex Model
Authors: Madrid Hector P. , Patterson Malcolm G. 
Published: July 2014

AbstractAffective states have become a central topic of interest in research on organizational behavior. Recently, scholars have been paying more attention to the proposals of the Circumplex Model (Russell, 1980) in order to gain a finer grained understanding of job-related affect. However, the limited availability of well-validated measures to test this model in work settings, particularly in non English-speaking populations, is still a major drawback. Using three samples of English-speaking and Spanish-speaking workers, this article offers the cross-validation of the Multi-Affect Indicator (Warr, 2007) between the original English version and its corresponding translation into Spanish. Multi-group Structural Equation Modeling supported the instrument’s structure and its invariance between the two languages (English: χ2= 65.56,df= 48,p= .05; RMSEA = .06; CFI = .97; Spanish: χ2= 68.68,df= 48,p= .03; RMSEA = .05; CFI = .97). Furthermore, Circular Stochastic Modeling supported the theoretically proposed circumplex representation (χ2= 139.85,df= 51,p< .01; χ2/df= 2.74, RMSEA = .06). Thus, this study offers an instrument that provides a more accurate approximation to affect at work, both in English and in another of the major language communities in the world, the Spanish-speaking population.

Authors: Ebersberger Sabine 
Published: July 2014

Der vorliegende Beitrag widmet sich dem Triptychon als therapeutische Methode in der Kunsttherapie. Triptychen sind dreiteilige Gemälde, die als sogenannte Flügelaltäre im 15. und 16. Jahrhundert Bekanntheit erlangten. In der Auseinandersetzung mit den therapeutischen Wirkfaktoren (vgl. Grawe, 2000 ; 2004 ) diskutiert der Beitrag die methodischen Stärken des Triptychons als Bildformat und zeigt auf, wie diese in der kunsttherapeutischen Arbeit praktisch nutzbar gemacht werden können. Exemplarische Bildbeispiele verdeutlichen diese Methode.
Hat Expressives Schreiben über eine positiv imaginierte Zukunft Einfluss auf Affekt, Copingstrategien und Selbstwirksamkeit?
Authors: Heimes Silke 
Published: July 2014

Das Expressive Schreiben (ES) hat sich in verschiedenen Untersuchungen als hilfreich bei der Verarbeitung belastender Ereignisse erwiesen und es haben sich mehr oder weniger deutliche positive Auswirkungen auf den psychologischen und physiologischen Gesundheitszustand gezeigt. Zunehmend beschäftigen sich Wissenschaftler mit der Frage, ob das ES bei der Formulierung von Lebenszielen zur Verbesserung von Selbstwirksamkeit und Affekt und als Copingstrategie geeignet sein könnte. 31 Studierende der Kunsttherapie und des Coachings wurden randomisiert zwei Gruppen zugeteilt, die beide an drei aufeinanderfolgenden Tagen für zwanzig Minuten entweder über eine positiv imaginierte Zukunft oder ein neutrales Thema schrieben. Untersucht wurden über einen Zeitraum von acht Wochen der positive und negative Affekt (PANAS), die Copingfähigkeiten (COPE) und die Selbstwirksamkeitserwartungen (SWE). In der Experimentalgruppe (EG) kam es nach der Schreibintervention zu einer Zunahme positiver Affekte im Vergleich zu den Ausgangswerten und zur Kontrollgruppe (KG), der sich im Follow-up allerdings verlor. In beiden Gruppen hatte das Schreiben keinen signifikanten Einfluss auf den negativen Affekt, die Copingfähigkeiten und die Selbstwirksamkeitserwartung. Schreiben über eine positiv imaginierte Zukunft vermag den positiven Affekt kurzzeitig zu steigern. Zur langfristigen Stimmungsverbesserung, einer Verbesserung der Copingfähigkeiten und einer Zunahme der Selbstwirksamkeitserwartung bedarf es möglicherweise einer längerdauernden Intervention und eines längeren Nachbeobachtungszeitraums.
Reducing handover delays for seamless multimedia service in IEEE 802.11 networks

Published: July 2014

In IEEE 802.11 wireless local area network (WLAN) environments, handovers occur when a mobile node (client) moves from the coverage area of one access point (AP) to that of another AP. In particular, a handover in multimedia streaming settings requires a series of tasks to be executed – recognising the disconnection to the currently associated AP, searching for other APs in client visibility and so on. The time taken to perform these tasks gives rise to an interruption of service for about 6 s, which greatly decreases users’ quality of experience (QoE). To reduce service disruptions caused by handovers in IEEE 802.11 networks, a soft proactive handover scheme that exploits the received signal strength indicator (RSSI) and scalable video coding (SVC) is proposed. The proposed scheme predicts the time that a handover process is going to start using the RSSI values and receives the lightweight base layer code of the SVC‐encoded video during a certain interval before the predicted handover starts. Experimental results show that the proposed scheme can minimise service interruption times during the 802.11 handover operations, thereby increasing QoE.
Ultra‐wideband unequal in‐phase power divider using three‐line coupled structure
Authors: Zhu H. , Abbosh A. , Guo L. 
Published: July 2014

A compact ultra‐wideband in‐phase power divider using a three‐line coupled structure is proposed. The power division of the device depends on the coupling factors between the centreline and the two sidelines. For an enhanced isolation between the output ports, a 100 Ω chip resistor is connected between the ends of the two sidelines, whereas the end of the centre line is grounded. To verify the design, a prototype with 2:1 power division was fabricated and tested. The measured results validate the ultra‐wideband performance with more than 12 dB return loss, more than 13 dB isolation and <0.2 dB and 4° amplitude and phase imbalances, respectively, across the band 3.1–10.6 GHz.
Voltage look‐up table method to control multilevel cascaded transformerless inverters with unequal DC rail voltages
Authors: Ebadi Mazdak , Joorabian Mahmood , Moghani Javad Shokrollahi 
Published: July 2014

This study presents a new voltage control algorithm for multilevel inverters which are used to connect the distributed generation (DG) sources (like photovoltaic cells) to the network, which is called the voltage look‐up table method (VLUTM). This method can build up an almost sinusoidal voltage at the inverter output with the least number of switching in the power circuit, and the best possible harmonic spectrum without the need to any big filtering. On the other hand, in some specific applications where the DG has been set up beside a non‐linear load, VLUTM can make a reference voltage based on the reference current to take a desired current form the DG. This way the DG can compensate the major low‐order load current harmonics and improve the source side current THD greatly. Decreasing the switching frequency as much as possible, which leads to better efficiency and less EMI problems, the capability of implementation both in single phase and three phase circuitry, and the very simple and desired current control, would be the major benefits of this method. The simulation results taken from Matlab/Simulink and the experimental results on a 1 kVA experimental prototype are presented to evaluate the performance of this method.
The fossilized birth–death process for coherent calibration of divergence-time estimates
Authors: Heath Tracy A. , Huelsenbeck John P. , Stadler Tanja 
Published: July 2014

Significance
Divergence time estimation on an absolute timescale requires external calibration information, which typically is derived from the fossil record. The common practice in Bayesian divergence time estimation involves applying calibration densities to individual nodes. Often, these priors are arbitrarily chosen and specified yet have an excessive impact on estimates of absolute time. We introduce the fossilized birth–death process—a fossil calibration method that unifies extinct and extant species with a single macroevolutionary model, eliminating the need for ad hoc calibration priors. Compared with common calibration density approaches, Bayesian inference under this mechanistic model yields more accurate node age estimates while providing a coherent measure of statistical uncertainty. Furthermore, unlike calibration densities, our model accommodates all the reliable fossils for a given phylogenetic dataset.

Significance
For mechanism-based development of treatment for Alzheimer’s disease (AD), the precise molecular mechanism of γ-secretase modulators (GSMs), which have been extensively developed as possible therapeutic reagents, is required. Here, we analyzed the mode of actions of phenylimidazole-type GSMs using a chemical biology approach and systematic mutagenesis. We provide the first structural model, to our knowledge, that binding of the phenylimidazole-type GSMs at the luminal loop of presenilin induces a conformational change of the catalytic center to reduce toxic amyloid-β species selectively. Our results may facilitate the effective development of AD therapeutics.
Substance Use and Mental Illness among Nurses: Workplace Warning Signs and Barriers to Seeking Assistance
Authors: Cares Alexa , Pace Elizabeth , Denious Jean , Crane Lori A. 
Published: July 2014

Background Although some studies have examined the prevalence of substance use among nurses, few have assessed substance use in the workplace or early cues for identifying these health conditions. Primary data collected as part of a larger program evaluation were examined with the purpose of better understanding (a) the context and perceived consequences of substance use and mental illness among nurses and (b) barriers and opportunities for earlier identification and treatment of these issues among nurses, their colleagues, and employers. Methods Anonymous surveys were mailed to 441 active and recent participants of a peer health assistance program in the summer of 2010. The survey examined drug-related behaviors in the workplace; behavioral cues that may permit earlier identification of substance use and mental illness; perceptions of barriers to seeking assistance; and strategies for preventing problems and overcoming barriers to seeking assistance. Results Responses were received from 302 nurses (69%). Nearly half (48%) reported drug or alcohol use at work, and two fifths (40%) felt that their competency level was affected by their use. More than two thirds of respondents thought their problem could have been recognized earlier. The most highly rated barriers to seeking assistance for substance use and mental illness included fear and embarrassment and concerns about losing one's nursing license. Respondents recommended greater attention be paid to early identification of risk factors during nurses’ professional training as a prevention strategy. Conclusions Findings from this study provide preliminary data that can be used by schools of nursing and health care employers to improve early identification of nurses’ substance use and mental illness treatment needs. These data also suggest a need for more research to explore the prevention and early identification of co-occurring disorders in health care settings where nurses practice.

Published: July 2014

Abstract
Macrophage infiltration in the adipose tissue, and the interaction with adipocytes, is well documented to be involved in fat inflammation and obesity-associated complications. In this study, we isolated IκB kinase ε (IKKε) as a key adipocyte factor that is potentially affected by interaction with macrophages in adipose tissue in vivo. We showed that IKKε mRNA expression levels in white adipose tissue were increased in both genetic and diet-induced obese mouse. Furthermore, IKKε mRNA expression was decreased by the administration of vitamin B6, an anti-inflammatory vitamin, and that IKKε expression levels in adipose tissue were closely correlated with the numbers of infiltrating macrophages. In a co-culture system, we showed that IKKε expression in adipocytes was upregulated by interaction with activated macrophages. This study provides novel insight into IKKε, which is involved in adipose tissue inflammation during the development of obesity.
VASCULAR PLANT ONE-ZINC FINGER1 and VOZ2 repress the FLOWERING LOCUS C clade members to control flowering time in Arabidopsis
Authors: Yasui Yukiko , Kohchi Takayuki 
Published: July 2014

Abstract
Floral transition is regulated by environmental and endogenous signals. Previously, we identified VASCULAR PLANT ONE-ZINC FINGER1 (VOZ1) and VOZ2 as phytochrome B-interacting factors. VOZ1 and VOZ2 redundantly promote flowering and have pivotal roles in the downregulation of FLOWERING LOCUS C (FLC), a central repressor of flowering in Arabidopsis. Here, we showed that the late-flowering phenotypes of the voz1 voz2 mutant were suppressed by vernalization in the Columbia and FRIGIDA (FRI)-containing accessions, which indicates that the late-flowering phenotype of voz1 voz2 mutants was caused by upregulation of FLC. We also showed that the other FLC clade members, MADS AFFECTING FLOWERING (MAF) genes, were also a downstream target of VOZ1 and VOZ2 as their expression levels were also increased in the voz1 voz2 mutant. Our results suggest that the FLC clade genes integrate signals from VOZ1/VOZ2 and vernalization to regulate flowering.
Minimalist, standard and no footwear on static and dynamic postural stability following jump landing

Published: July 2014

AbstractIn recreational sports, uncushioned, light‐weight and minimalist shoes are increasingly used to imitate barefoot situations. Uncertainty exists whether these shoes provide sufficient stability during challenging movements. In this randomised crossover study, 35 healthy distance runners performed jump landing stabilisation and single‐leg stance tests on a force plate, using four conditions in random order: barefoot, uncushioned minimalist shoes, cushioned ultraflexible shoes and standard running shoes. Ground reaction force (GRF) and centre of pressure (COP) data were used to determine unilateral jump landing stabilisation time and COP sway velocity during single‐leg stance. Repeated measures analysis of variance revealed significant footwear interactions for medial–lateral (p < 0.001) and anterior–posterior COP sway velocity during standing (p < 0.001). The barefoot condition produced significantly greater postural sway velocities (p < 0.001) compared to all footwear conditions. No significant effects were found for jump landing stabilisation time. In conclusion, the results of this study indicate that increased shoe flexibility and reduced sole support have no, or only minor influence on static and dynamic postural control, and therefore, may not increase the risk of traumatic events during sports activities. However, barefoot conditions should be considered carefully when adequate postural control is needed.
Competitive binding-based optical DNA mapping for fast identification of bacteria - multi-ligand transfer matrix theory and experimental applications on Escherichia coli

Abstract
We demonstrate a single DNA molecule optical mapping assay able to resolve a specific Escherichia coli strain from other strains. The assay is based on competitive binding of the fluorescent dye YOYO-1 and the AT-specific antibiotic netropsin. The optical map is visualized by stretching the DNA molecules in nanofluidic channels. We optimize the experimental conditions to obtain reproducible barcodes containing as much information as possible. We implement a multi-ligand transfer matrix method for calculating theoretical barcodes from known DNA sequences. Our method extends previous theoretical approaches for competitive binding of two types of ligands to many types of ligands and introduces a recursive approach that allows long barcodes to be calculated with standard computer floating point formats. The identification of a specific E. coli strain (CCUG 10979) is based on mapping of 50–160 kilobasepair experimental DNA fragments onto the theoretical genome using the developed theory. Our identification protocol introduces two theoretical constructs: a P-value for a best experiment-theory match and an information score threshold. The developed methods provide a novel optical mapping toolbox for identification of bacterial species and strains. The protocol does not require cultivation of bacteria or DNA amplification, which allows for ultra-fast identification of bacterial pathogens.
