Investigating mediation styles of second language listener verbal reports
Authors: Yeldham Michael , Chen Rainbow Tsai-Hung 
Published: May 2016

Abstract
This study investigated verbal report styles for eliciting strategies data from second language listeners. It examined outcomes from three different mediation (prompting) styles, one style unprompted and the two others prompted, after the learners were first provided with low-prescriptive instructions on how to complete the report. Also, the unprompted style was additionally examined after the provision of more-prescriptive instructions to observe the effect of this greater learner guidance. Theoretically, the core of the study examined two competing cognitive perspectives on verbal reporting. One, from an information processing perspective, is that verbal reports elicit the best insight into individuals’ strategic processes when prompts are kept to a minimum. The other perspective, a constructivist one, advocates the use of prompts in the form of researcher questions, mainly to help guide the report. Seventeen Taiwanese EFL learners participated in the study, with data gathered from each through a verbal report followed by a semi-structured interview. It was found that researcher prompting was both strongly favored by the learners and clearly elicited the best data for second language listener strategies research. The results also indicated that unprompted reports were little more effective when preceded by more-prescriptive instructions.

AbstractDuring the past few years, scientists have shown that climate change is a serious problem that mandates adequate solutions. Greenhouse gas emissions such as carbon dioxide contribute to heat trapping in the atmosphere, which increases the global temperature. Reducing greenhouse gas emissions and the carbon footprint to zero is an essential step toward maintaining a 2°C temperature change. In doing so, researchers and scientists have focused much attention on finding alternative technologies that provide clean and sustainable energy. In particular, nanotechnology can offer this alternative solution to the ongoing energy crisis. The recent progress in nanomaterial research has focused on the development of high-efficiency optoelectronics, batteries, low-power electronics, and thermoelectric devices for energy generation applications. With the emergence of new nanomaterials, such as carbonaceous materials and transition metal dichalcogenides, new physics have emerged. Scientists and engineers are still eager to answer some of the fundamental issues concerning these nanomaterials, including optical, electrical, and thermal properties. Yet, to this day, nanotechnology solutions to provide a sustainable energy are hinged by the ability to control and fully understand the properties of these nanomaterials. Here, we highlight some of the recent progress carried out in nano-optoelectronics, and share our thoughts on the opportunities and challenges facing low-dimensional devices to generate clean and sustainable energy.
Zum Ursprung der Stabdolche und stabdolchartiger Waffen in Europa
Authors: Horn Christian , Schenck Tine 
Published: May 2016

ZusammenfassungStabdolche gelten nach wie vor in weiten Teilen der europäischen Forschung als relativ kurzlebige Erscheinung der Frühbronzezeit. In diesem Beitrag wird für eine erste Nachweisbarkeit von Stabdolchen aus Kupfer und Kupferlegierungen in der ersten Hälfte des 4. Jts. v. Chr. plädiert. Im Weiteren wird aufgezeigt, dass die Idee, Klingen und Spitzen stabdolchartig zu schäften, bereits im vierten und frühen dritten Jts. v. Chr. von Zentralitalien bis nach Südskandinavien weit verbreitet war. Diskutiert werden eine rechtwinklige Schäftung und der Gebrauch „dicker Spitzen“ der Trichterbecherkultur als Waffe. In die Diskussion einbezogen werden Gebrauchsspuranalysen von 115 Klingen. Erörtert wird eine Waffenfunktion der sog. Geweihspitzen aus den Seeufersiedlungen der Schweiz sowie der Versuch einiger Forscher, die Idee, Waffen stabdolchartig zu schäften, zeitlich und geografisch zu verorten. Als technologischer Ursprung werden Werkzeuge benannt, die es aufgrund ihrer Multifunktionalität möglich erscheinen lassen, dass sich Stabdolche als innovative neue Waffe an verschiedenen Orten und zu unterschiedlichen Zeiten entwickelten.
Innovations in European Bronze Age textiles

Published: May 2016

ZusammenfassungWährend der Bronzezeit kam es in Europas nach dem Aufkommen von Wolle als neuem Rohstoff zu einer Reihe von Innovationen im Bereich der Textilien. Neue Analysen und die Nutzung der SEMMikroskopie erbrachten eine Vielzahl von Informationen zur Verwendung von Pflanzenfasern und Wolle, insbesondere zur Frage, wie und in welchem Umfang Wolle vor dem Spinnen sortiert und verarbeitet wurde. Als weitere Neuerungen anzuführen sind die Dekoration von Textilien durch Stickereien und die Köperbindung. Auch die Werkzeuge zur Textilbearbeitung veränderten sich, um Wolle verarbeiten zu können. Der Beitrag stellt Nachweise für die Faserverarbeitung vor und beschreibt, wie das Aufkommen der Wolle weitere Innovationen in der Textilherstellung nach sich zog.
Bronzization: The Bronze Age as Pre-Modern Globalization
Authors: Vandkilde Helle 
Published: May 2016

ZusammenfassungIst es möglich, die Bronzezeit im Sinne der soziologisch definierten Begrifflichkeit “Globalisierung” zu fassen? Der Beitrag folgt dieser Fragestellung auf analytischem Wege, aber auch in der Diskussion ihrer Merkmale auf Basis moderner und zeitgenössischer Geschichtsschreibung. Sichtbar wird, dass die Bronzezeit als einzigartiges Beispiel der Verschränkung eines kontinentübergreifenden afrikanisch-eurasischen Großraumes anzusehen ist, der sich um etwa 2000 v. Chr. herausbildete und um ca. 1200 v. Chr. wieder verschwand. Um die Bronzezeit als ein entsprechend globalisiertes Phänomen betrachten zu können, wurde der Begriff “bronzization” eingeführt, der die Bronze als entscheidende Ressource eines historischen Wandels über den Zeitraum von 800 Jahren fasst und in den Mittelpunkt der Forschung stellt.
Eine Insel der Pazifisten im Meer der Krieger? Anmerkungen zu einem Grabinventar von Aasø, Seeland
Authors: Przybył* Marzena J. 
Published: May 2016

ZusammenfassungDer Artikel behandelt das in der zweiten Hälfte des 19. Jahrhunderst zufällig entdeckte Männergrab von Aasø auf Seeland. Seine Ausstattung gehört zu den reichsten Männerbestattungen Seelands der spätrömischen Kaiserzeit. Neben einem Satz von provinzialrömischen Gefäßen, Spielsteinen, Spielbrett-, Horn- und Gürtelbeschlägen, wurden in ihm – was untypisch für die Bestattungssitten Seelands ist – Bewaffnungselemente gefunden. Das Inventar ist Ausgangspunkt für Erörterungen hinsichtlich des „Waffentabus“ im Bestattungsritual auf Seeland – eines Brauches, der diese Insel von benachbarten Gebieten über die gesamte jüngere vorrömische Eisenzeit, römische Kaiserzeit und frühe Völkerwanderungszeit unterscheidet. Besprochen werden auch formale und technologische Merkmale des im Inventar von Aasø gefundenen Schildbuckels, der zwar anderen zeitgleichen Schildbuckeln aus Nordeuropa entspricht, der aufgrund seiner Herstellungsweise aber deutlich an römische Erzeugnisse erinnert.Ein separates Thema, das in Zusammenhang mit im Grab gefundenen Gürtelteilen zur Sprache kommt, sind die bisher wenig deutlichen Verbindungen Seelands mit dem südöstlichen Ostseeraum.Weil keine Angaben über die Lage der Inventarteile im Grab von Aasø vorliegen, mussten sie anhand der Angaben über andere spätrömerzeitliche Gräbern von Seeland rekonstruiert werden. In Anlehnung an die zugänglichen Daten in diesem Bereich lassen sich einige allgemeine Regelmäßigkeiten hinsichtlich der Deponierungsweise der Beigaben in spätkaiserzeitlichen seeländischen Gräbern feststellen. Weiterhin wird auch eine Analyse zur sozialen Differenzierung der in den Gebieten entlang des Flusses Suså ehemals siedelnden Populationen vorgestellt. Diese mikroregionale Untersuchung kann anhand der aus jener Region bekannten spätrömischen Grabinventare, wie z. B. auch das Grabinventar von Aasø, durchgeführt werden.
Estimating stochastic volatility models using realized measures
Authors: Bekierman Jeremias , Gribisch Bastian 
Published: May 2016

AbstractThis paper extends the basic stochastic volatility (SV) model in order to incorporate the realized variance (RV) as an additional measure for the latent daily volatility. The particular model we use explicitly accounts for the dependency between daily returns and measurement errors of the realized volatility estimate. Within a simulation study we investigate the form of the dependency. In order to capture the long memory property of asset volatility, we explore different autoregressive dynamics for the latent volatility process, including heterogeneous autoregressive (HAR) dynamics and a two-component approach. We estimate the model using simulated maximum likelihood based on efficient importance sampling (EIS), producing numerically accurate parameter estimates and filtered state sequences. The model is applied to daily asset returns and realized variances of New York Stock Exchange (NYSE) traded stocks. Estimation results indicate that accounting for the dependency of returns and realized measures significantly affects the estimation results and improves the model fit for all autoregressive dynamics.
Olive Mill Wastewater (OMW) Phenol Compounds Degradation by Means of a Visible Light Activated Titanium Dioxide-Based Photocatalyst

Abstract
The use of titanium dioxide as heterogeneous photocatalyst is drawing considerable attention for water and air
purification and remediation. Recently, TiO2 particles have been modified in order to make this material
attractive for industrial and environmental remediation usage. In the present study, phenolic compounds of olive mill
wastewater (OMW) were degraded in the presence of glucose-doped titanium particles (CDT) through a photocatalysis process
activated by visible light. The photocatalyst effectiveness towards the polluted wastewater from olive oil industry was
tested on systems having different initial concentrations of phenols and in the presence of different amounts of CDT. For
kinetic analysis the role of Ti/TPh ratio (amount of catalyst/amount of total phenols) was
investigated. The rate constant (k
2) and the amounts of species adsorbed on adsorbent at equilibrium (q

e
) of
each reaction were calculated by fitting kinetics data to a second-order kinetic adsorption model. The results collected
at different Ti/TPh ratios showed that the amount of phenols that can be removed from the water solution
linearly increases with the Ti/TPh ratio till a maximum value (optimal ratio) at which no further
degradation of phenolic compounds was obtainable. Such kind of parameter allows to identify the optimal value of catalyst
and the initial substrate concentration for a high level of degradation. The results showed in this study can have an
important impact for an applicative point of view.

<p>La producción de biomasa y pigmentos a partir de Arthrospira platensis ha cobrado gran importancia, debido a que estos tienen aplicaciones en producción de alimentos, metabolitos de interés biotecnológico e industrial. No obstante, para la producción de biomasa y pigmentos se han utilizadodiversos sustratos que generan altos costos. Se estudió el crecimiento y producción de pigmentos de A. platensis bajo la influencia de seis concentraciones de carbón de bajo rango (CBR) tipo lignito (10, 20, 30, 40, 50, 60 mg/L) frente a una concentración de AIA (80 mg/L), se realizaron cultivos en batch en medio Zarrouk suplementados con CBR tipo lignito y AIA, bajo condiciones de aireación constante y fotoperiodos de 12:12 horas, durante 33 días. Los valores promedios más altos que se obtuvieron en cuanto a producción de biomasa y pigmentos se lograron en los cultivos suplementados con 50 y 60 mg/L de CBR tipo lignito con respecto a los controles. Los resultados obtenidos dan constancia al uso potencial del CBR como materia orgánica humificada, rica en nutrientes para el cultivo A. platensis que podrían ser aprovechado en medios acuíferos que son expuestos a la explotación carbonífera, contribuyendo a procesos de depuración y biorremediación de aguas contaminadas con materiales carboníferos.</p>

ABSTRACTLead halide perovskites have proven their great power conversion efficiency (PCE) in the last few years and attracted more and more attentions. Evaporation is an important method to get high quality perovskite films, especially for surface and interface investigation, which is important for the solar cell performance. In this paper, we present our investigations on growing PbI2 and CH3NH3I films by evaporation, and then CH3NH3PbI3 films by co-evaporation. X-ray photoemisson spectroscopy (XPS) was used to characterize the films. The results showed that CH3NH3I film was not stable in vacuum. Both N and I decreased in vacuum with time elapsing. PbI2 and CH3NH3PbI3 films are quite stable. The atomic ratio of CH3NH3PbI3 films (C: N: Pb: I =1.29:1.07:1.00:2.94) is very close to the ideal CH3NH3PbI3, which indicates that evaporation is a good method to get high quality perovskite films with accurate atomic ratio.
Early Craniofacial Defects in Zebrafish that Have Reduced Function of a Wnt-Interacting Extracellular Matrix Protein, Tinagl1

Published: May 2016

Objective Tinagl1 has a weak genetic association with craniosynostosis, but its functions in cartilage and bone development are unknown. Knockdown of Tinagl1 in zebrafish embryos allowed an initial characterization of its potential effects on craniofacial cartilage development and a test of whether these effects could involve Wnt signaling. Results Tinagl1 knockdown resulted in dose-dependent reductions and defects in ventral pharyngeal arch cartilages as well as the ethmoid plate, a zebrafish correlate to the palate. These defects could be correlated to reduced numbers of cranial neural crest cells in the pharyngeal arches and could be reproduced with comanipulation of Tinagl1 and Wnt3a by morpholino-based knockdown. Conclusions These results suggest that Tinagl1 is required early in the proliferation or migration of cranial neural crest cells and that its effects are mediated via Wnt3a signaling. Because Wnt3a is among the Wnts that contribute to nonsyndromic cleft lip and cleft palate in mouse and man, further investigation of Tinagl1 may help to elucidate mechanisms underlying these disorders.

Immersion Pulmonary Edema in the setting of Takotsubo Cardiomyopathy
Authors: Reed Tara Mireille 
Published: May 2016

<p>Immersion Pulmonary Edema (IPE) is a unique medical condition being increasingly described in the medical literature as sudden-onset pulmonary edema in the setting of scuba diving and/or swimming. We report on three patients with unique presentations of IPE with associated development of Takotsubo cardiomyopathy (TTC). All three cases occurred in Oahu, Hawaii and were seen by the same cardiologist within a span of seven years. Each patient was scuba diving with sudden onset dyspnea with pulmonary edema on chest x-ray. Cardiac catheterization revealed no significant epicardial stenosis or thrombosis. EKGs showed typical evolution of symmetric T wave inversion. Wall motion abnormalities resolved. IPE and TTC may occur together and may be more common than initially thought. Physical and emotional stressors are known to trigger TTC. TTC should be considered as a possible complication of IPE. Initial workup should include EKGs, cardiac enzymes, echocardiogram and, in the appropriate situation, cardiac catheterization. </p>

Resumo Na primeira parte deste artigo, mencionamos as obras do escritor alemão Georg Büchner (1813-1837), considerando especialmente o drama Woyzeck. Ressaltamos a novidade temática e estética dessa peça, pioneira em apresentar um homem despossuído no papel principal, obra com a qual Büchner se converteria em precursor de naturalistas e expressionistas. Nas seces finais, abordamos as razões para compor a peça Zé, adaptação em verso e canções de Woyzeck. O verso pode conferir ao texto certas qualidades musicais, as quais ampliam o campo de significações da peça teatral. Exemplos tomados a Zé são utilizados para expor tais hipóteses.
