Improving Reading Comprehension and Social Studies Knowledge in Middle School
Authors: Vaughn Sharon , Swanson Elizabeth A. , Roberts Greg , Wanzek Jeanne , Stillman‐Spisak Stephanie J. , Solis Michael , Simmons Deborah 
Published: December 2016

AbstractThis study aimed to determine the efficacy of a content acquisition and reading comprehension treatment implemented by eighth‐grade social studies teachers. Using a within‐teacher design, the eighth‐grade teachers’ social studies classes were randomly assigned to treatment or comparison conditions. Teachers (n = 5) taught the same instructional content to both treatment and comparison classes, but the treatment classes used instructional practices focused on teaching essential words, text as a source for reading and discussion, and team‐based learning approaches. Students in the treatment conditions (n = 261) scored statistically higher than students in the comparison conditions (n = 158) on all three outcomes: content acquisition (ES = 0.17), content reading comprehension (ES = 0.29), and standardized reading comprehension (ES = 0.20). Findings are interpreted as demonstrating support for the treatment in improving both knowledge acquisition and reading comprehension within content area instruction.

Published: December 2016

AbstractBecause chronic stress is an important risk factor for anxiety states and depressive disorders, we studied hypothalamus–pituitary–adrenal (HPA) axis and sympathetic system activity via changes in cortisol and alpha amylase activity levels in pediatric generalized anxiety disorder (GAD) patients (n = 26) with comorbid depression and a healthy comparison group (n = 26). Morning plasma cortisol and diurnal profiles of salivary cortisol and salivary alpha amylase (sAA) activity were assessed, also reactivity of HPA‐axis, sAA activity, and heart rate following a psychosocial stressor (Trier Social Stress Test for children). GAD patients with comorbid depression showed increased morning plasma and salivary cortisol levels, ameliorating throughout in‐patient treatment, and higher sAA activity in their diurnal profile. Both HPA and sympathetic activity positively correlated with the severity of anxiety and depression. We also demonstrated a blunted HPA and sympathetic response to acute stress in patients. This pattern of neuroendocrine and sympathetic changes seems to be distinct from the one previously reported in pediatric patients with only social anxiety or depressive disorders. We propose morning plasma and saliva cortisol levels as potential physiological indicators for supporting the evaluation of symptoms' severity and treatment progress in children with GAD and comorbid depressive disorder.
Top management team incentive heterogeneity, strategic investment behavior, and performance: A contingency theory of incentive alignment
Authors: Steinbach Adam L. , Holcomb Tim R. , Holmes R. Michael , Devers Cynthia E. , Cannella Albert A. 
Published: December 2016

Research summary: We develop and test a contingency theory of the influence of top management team (TMT) performance‐contingent incentives on manager–shareholder interest alignment. Our results support our theory by showing that although TMTs engage in significantly higher levels of acquisition investment when their average incentive levels increase, investors' responses to those large investments are generally negative. More importantly, however, we further find that within‐TMT incentive heterogeneity conditions that effect, such that investors evaluate TMTs' large acquisition investments more positively as the variance in those top managers' incentive values increases. Thus, within‐TMT incentive heterogeneity appears to increase manager–shareholder interest alignment, in the context of large acquisition investments.Managerial summary: We find that as the average value of TMTs' incentives increase, relative to their total pay, they invest more in acquisitions and investors' respond negatively to the announcement of those deals. However, we further show that investors respond more positively to acquisitions announced by TMTs whose members' incentive values vary (some TMT members hold higher incentives and others hold lower). Results imply that when TMT members hold differing incentives levels, they approach investments from divergent perspectives, scrutinize those investments more heavily, and make better decisions, relative to TMTs with similar incentives. They also suggest that boards seeking tighter manager–shareholder interest alignment may benefit from introducing variance into TMT members' incentive structures, as doing so appears to create divergent preferences that can improve team decision making.

Musculoskeletal pain and injury in sonographers, causes and solutions
Authors: Pallotta O. J. , Roberts A. 
Published: December 2016

AbstractIntroductionScanning a patient involves pushing a heavy transducer and a heavy cord while simultaneously leaning over a patient, using the keyboard and viewing the screen. Even with good patient and machine position, a sonographer's upper limbs can be abducted up to 90º from the body that can place the body under stress. International statistics indicate that 80–95% of sonographers experience work‐related pain, 90% experience this pain for more than half their career and one in five sonographers sustain a career ending work‐related injury.MethodsThe sonographer safety initiative is a collaborative effort between sonographers, biomedical engineers in SA Health, Flinders Biomedical Enterprises and GE Healthcare; with the goal to investigate sonographer work‐place injuries. A 6‐month study was conducted that reviewed literature, compensation claims, injury reports, and surveyed sonographers and relevant stakeholders.ResultsInformation regarding the social/cultural, physiological/environmental and technological issues in current practices was collected along with the causes and rates of sonographer injuries.DiscussionMusculoskeletal disorders are a significant concern for sonographers with detrimental effects on the individual and the employer. Sonographers are reluctant to report or claim these injuries, which mask the problem and prevent it from getting the traction it requires.
Definition of REST web services with JSON schema
Authors: Barbaglia Guido , Murzilli Simone , Cudini Stefano 
Published: December 2016

SummaryThe Web has evolved from being a collection of documents to a collection of interconnected services that interoperate throughout the Internet. Web services are a natural consequence of this evolution. The web services model was initially centered around the eXtensible Markup Language (XML). Such services can be described by Web Services Description Language documents that are formally defined through the XML Schema Definition language. However, in recent years the popularity of XML‐based web services has declined, as more developers favor JavaScript Object Notation (JSON)‐based alternatives. Although the use of the latter language is spreading, no official standard to formally describe JSON documents exists. The aim of this article is to demonstrate how JSON Schema, and particularly the JSON Hyper Schema extension, is suitable to describe JSON‐based web services that follow the REST architectural pattern.

Untersuchung zur Kantenfestigkeit von Floatglas in Abhängigkeit der Kantenbearbeitung
Authors: Kleuderlein Jonas , Ensslen Frank , Schneider Jens 
Published: December 2016

AbstractFür die Bemessung von Standard‐Verglasungen gewinnt die Kantenfestigkeit von Floatglas zukünftig an Bedeutung, vor allem im Hinblick auf den thermisch induzierten Bruch. DIN 1249‐11 definiert bisher rein visuelle und geometrische Merkmale. Jedoch wird die Glaskantenfestigkeit in Abhängigkeit von der Bearbeitungsart derzeit noch unzureichend betrachtet. Unter Federführung des Arbeitskreises “Kantenfestigkeit“ beim Fachverband Konstruktiver Glasbau e.V. (FKG) wurden verschiedene Arten der Kantenbearbeitungen optisch und experimentell untersucht sowie statistisch ausgewertet. Die Analyse der Versuche erlaubt eine erste Abschätzung zur Korrelation der Kantenfestigkeit mit der Kantenbearbeitungsart und bezüglich des Einflusses von Produktionsparametern.Study on edge strength of float glass as a function of edge processing. For the design of glazing the edge strength of annealed float glass becomes more and more important. In current standards the edge quality is defined by visual and geometric characteristics only. The strength of the glass edge, depending on the type of processing, however, is considered insufficiently in standards. In cooperation with the working group “edge strength” at Fachverband Konstruktiver Glasbau e.V. (FKG) different types of edge processing were investigated experimentally, and evaluated statistically. The analysis of the experiments gives a first estimate for the correlation between edge strength and the edge processing, considering the variation of production factors.
Fassadenintegration von Dünnschicht‐Photovoltaik‐Paneelen mit rückseitigem Latentwärmespeicher

Published: December 2016

AbstractOpake Fassadenbereiche besitzen ein großes Potential zur Erzeugung von Energie durch den Einsatz von Photovoltaik (PV)‐Modulen. Die Leistung dieser Module sinkt mit zunehmender Temperatur der PV‐Zellen, wodurch sich die Verwendung im Fassadenbereich bisher hauptsächlich auf Kaltfassaden beschränkt hat. Im Unterschied zu Kaltfassaden ist bei standardmäßigen Pfosten‐Riegel‐Fassaden eine Hinterlüftung zur Kühlung der Module nicht möglich. Um auch hier den Einsatz von PV‐Modulen zu ermöglichen und gleichzeitig einen temperaturbedingten Leistungsabfall zu minimieren, sollen die PV‐Module mit rückseitig angebrachten Phasenwechselmaterialien (PCM) kombiniert werden. Erreicht die Temperatur in der Fassade den frei einstellbaren Schmelzpunkt des PCM, erfolgt ein Phasenübergang von fest zu flüssig. Dabei absorbiert das Material thermische Energie und entzieht sie auf diese Weise dem PV‐Modul, sodass ein Temperaturanstieg in den PV‐Zellen abgepuffert wird. Nachts wird die im PCM latent gespeicherte Wärmeenergie wieder an die Umgebung abgebeben.Façade integration of thin‐film photovoltaic panels with rear‐mounted phase change material (PCM). Opaque façade areas feature a great potential for generating energy by using PV modules. Their use in the façade sector has so far been limited mainly to cold fronts because the performance of these modules drops with increasing temperatures of the PV cells. In contrast to cold fronts, a rear ventilation to cool the modules is not possible in standard mullion and transom façades. To ensure low module temperatures and thus a high performance, the PV modules are to be combined with rear‐mounted phase‐change materials (PCM). When the temperature in the façade reaches the freely adjustable melting point of the PCM, it results in a phase transition from solid to liquid. The material absorbs thermal energy from the PV‐module and the rising of module temperature can be buffered. At night, the thermal energy latently stored in the PCM is released back into the ambient air.

Published: December 2016

AbstractDer vorliegende Artikel beschreibt die herausragende Leistungsfähigkeit einer in eine Vielzahl von Bildpunkten strukturierten, schaltbaren Flüssigkristallverglasung. Durch die Unterteilung in kleine, einzeln ansteuerbare Bereiche, die individuell verdunkelt werden können, ergibt sich weltweit erstmals die Möglichkeit, die Blendschutzfunktion von der Helligkeitsregelung des Raumes zu entkoppeln. Dies ermöglicht insbesondere in der Heizperiode, wenn Solarstrahlungsgewinne durch die Fassade erwünscht sind, die Möglichkeit der Nutzung dieser Gewinne bei gleichzeitiger Gewährleistung der Blendfreiheit für den Nutzer. Nachfolgend vorgestellt werden das Strukturierungskonzept, der Aufbau der Verglasungen sowie die Messkampagne während des Betriebs der Verglasungen im Fassadentestgebäude des ILEK.Potential of Pixelated Switchable Glazing. In this paper the extraordinary performance of multi‐pixeled switchable glazing is described. The façade depicted here is the first façade worldwide which is subdivided into small, individually controlled and individually dimmable sections thus creating the possibility to operate a room’s glare protection separate from the brightness control. In this way glare protection can be provided even during the heating period when the glazing should allow for the transmission of solar radiation. In this paper the structuring of the pixels, the design of the glazing and the measurement campaign during the operation of the façade prototype will be described.
Vom Bieten zum Bauen – Transparenz im Spannungsfeld von Markt und Machbarkeit
Authors: Frey Hans 
Published: December 2016

AbstractIn Zeiten knapper Budgets und damit einhergehend stark verzögerter Entscheidungsprozesse durchläuft ein Entwurf vielfache Entwicklungsstufen und langwierige Angebotsverfahren, in dem das Konzept unterschiedlichsten Einflussfaktoren standhalten muss. Häufig sind die Gebäudehüllen erstes Opfer von Einsparmaßnahmen. Es gibt essentielle Unterschiede im Ablauf von gewöhnlichen Bauprojekten im klassischen Vergabeverfahren, die sich eher Standardsystemen bedienen, oder solchen, die nach innovativen und herausfordernden Lösungen in Konzept und Detail verlangen. Für den Projekterfolg und die Durchsetzung des Konzeptes zahlt sich aus, über Leistungsgrenzen hinaus zu denken, Markt und Machbarkeit in der Planung widerzuspiegeln. Wie die Fallbeispiele aus Baku zeigen, empfiehlt sich frühzeitig ein starkes Team unter Einbindung der Schlüsselgewerke zu bilden, das auf partnerschaftlicher Basis zusammenarbeitet, um das bestmögliche Projektergebnis durch Leistungs‐ und Terminoptimierung zu erzielen.From bid to building – transparency as merger of market and constructability. At times of tight budgets and thus strongly delayed decision making a design has to sustain many influences in the course of multiple developmental stages and long bid processes. Oftentimes building envelopes are the first target of a value engineering processes. There is a significant difference in the delivery process of projects using standard systems and challenging projects including innovations and exceptional design or construction elements. For a successful delivery of such special projects it pays off to look beyond scope boundaries and to consider market and feasibility at the design stage. The case studies from Baku show that it pays off to form a team involving key trades early on that collaborates on a partnership basis to deliver the best possible result by optimising performance and schedule.
Physical layer architectures for machine type communication networks—a survey
Authors: Huang Yi‐Feng , Chen Hsiao Hwa 
Published: December 2016

AbstractMachine‐type communication (MTC) has attracted much attention due to the fact that it provides pervasive connections for billions of MTC devices, forming a basis for the Internet of things. Most works in the literatures on machine‐to‐machine (M2M) communications focused on media access layer (MAC) layer or other upper layer applications, such as e‐health, energy management and entertainment services. On the other hand, physical (PHY) layer plays a pivotal role in M2M communications. To accommodate a large number of MTC devices, M2M should be made efficient enough in terms of its power consumption and spectrum utilisation. Copyright © 2016 John Wiley & Sons, Ltd.
Characterizing multi‐hop localization for Internet of things

Published: December 2016

AbstractDeployments over large geographical areas in the Internet of Things (IoT) pose a major challenge for single‐hop localization techniques, giving rise to applications of multi‐hop localizations. And while many proposals have been made on implementations for multi‐hop localization, a close understanding of its characteristics is yet to be established. Such an understanding is necessary, and is inevitable in extending the reliability of location based services in IoT. In this paper, we study the characteristics of multi‐hop localization and propose a new solution to enhance the performance of multi‐hop localization techniques. We first examine popular assumptions made in simulating multi‐hop localization techniques, and offer rectifications facilitating more realistic simulation models. We identify the introduced errors to follow the Gaussian distribution, and the estimated distance follows the Rayleigh distribution. We next use our simulation model to characterize the effect of the number of hops on localization in both dense and sparse deployments. We find that, contrary to common belief, it is better to use long hops in sparse deployments, while short hops are better in dense deployments – despite the traffic overhead. Finally, we propose a new solution that decreases and manages the overhead generated during the localization process. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
Human milk is essential for the initial development of newborns, as it provides all nutrients and vitamins, such as vitamin D, and represents a great source of commensal bacteria. Here we explore the microbiota network of colostrum and mature milk of Italian and Burundian mothers using the auto contractive map (AutoCM), a new methodology based on artificial neural network (ANN) architecture. We were able to demonstrate the microbiota of human milk to be a dynamic, and complex, ecosystem with different bacterial networks among different populations containing diverse microbial hubs and central nodes, which change during the transition from colostrum to mature milk. Furthermore, a greater abundance of anaerobic intestinal bacteria in mature milk compared with colostrum samples has been observed. The association of complex mathematic systems such as ANN and AutoCM adopted to metagenomics analysis represents an innovative approach to investigate in detail specific bacterial interactions in biological samples.

AbstractDendritic cells (DCs) have been implicated in the pathogenesis of psoriasis but the roles for specific DC subsets are not well defined. Here we show that DCs are required for psoriasis-like changes in mouse skin induced by the local injection of IL-23. However, Flt3L-dependent DCs and resident Langerhans cells are dispensable for the inflammation. In epidermis and dermis, the critical DCs are TNF-producing and IL-1β-producing monocyte-derived DCs, including a population of inflammatory Langerhans cells. Depleting Ly6Chi blood monocytes reduces DC accumulation and the skin changes induced either by injecting IL-23 or by application of the TLR7 agonist imiquimod. Moreover, we find that IL-23-induced inflammation requires expression of CCR6 by DCs or their precursors, and that CCR6 mediates monocyte trafficking into inflamed skin. Collectively, our results imply that monocyte-derived cells are critical contributors to psoriasis through production of inflammatory cytokines that augment the activation of skin T cells.

Published: December 2016

AbstractThe use of electric fields for signalling and control in liquids is widespread, spanning bioelectric activity in cells to electrical manipulation of microstructures in lab-on-a-chip devices. However, an appropriate tool to resolve the spatio-temporal distribution of electric fields over a large dynamic range has yet to be developed. Here we present a label-free method to image local electric fields in real time and under ambient conditions. Our technique combines the unique gate-variable optical transitions of graphene with a critically coupled planar waveguide platform that enables highly sensitive detection of local electric fields with a voltage sensitivity of a few microvolts, a spatial resolution of tens of micrometres and a frequency response over tens of kilohertz. Our imaging platform enables parallel detection of electric fields over a large field of view and can be tailored to broad applications spanning lab-on-a-chip device engineering to analysis of bioelectric phenomena.

AbstractIn the past years, magnetism-driven ferroelectricity and gigantic magnetoelectric effects have been reported for a number of frustrated magnets featuring ordered spiral magnetic phases. Such materials are of high-current interest due to their potential for spintronics and low-power magnetoelectric devices. However, their low-magnetic ordering temperatures (typically <100 K) greatly restrict their fields of application. Here we demonstrate that the onset temperature of the spiral phase in the perovskite YBaCuFeO5 can be increased by more than 150 K through a controlled manipulation of the Fe/Cu chemical disorder. Moreover, we show that this novel mechanism can stabilize the magnetic spiral state of YBaCuFeO5 above the symbolic value of 25 °C at zero magnetic field. Our findings demonstrate that the properties of magnetic spirals, including its wavelength and stability range, can be engineered through the control of chemical disorder, offering a great potential for the design of materials with magnetoelectric properties beyond room temperature.
