The influence of mold temperature on thermoset in-mold forming
Authors: Deringer Tim , Drummer Dietmar 
Published: January 2020

Abstract
A new process, called thermoset in-mold forming, for combining thermoset master forming and thermoset forming in one mold is in development. A pre-impregnated continuous-fiber reinforced sheet based on epoxy (prepreg) is formed in the injection molding machine, followed by instantaneous overmolding of a short-fiber reinforced epoxy compound in one step. Compared with conventional processes in which thermoset injection molding, prepreg compression molding, and hence curing of the materials are separated, the new process allows for the combination in one step and simultaneous curing of both components. The result is a hybrid component, which features a continuous-fiber reinforced part for higher mechanical performance and a short-fiber reinforced part with high design freedom for integration of additional functions. For a successful combination of both materials in one process, it is essential to investigate the bond strength between them in relation to the processing parameters and their influence on the degree of cure. This paper analyzes the influence of the mold temperature in this process on curing degree, bond strength, and the processing viscosity.
Arbitrage-free interpolation of call option prices
Authors: Bender Christian , Thiel Matthias 
Published: January 2020

Abstract
In this paper, we introduce a new interpolation method for call option prices and implied volatilities with respect to the strike, which first generates, for fixed maturity, an implied volatility curve that is smooth and free of static arbitrage.
Our interpolation method is based on a distortion of the call price function of an arbitrage-free financial “reference” model of one’s choice.
It reproduces the call prices of the reference model if the market data is compatible with the model.
Given a set of call prices for different strikes and maturities, we can construct a call price surface by using this one-dimensional interpolation method on every input maturity and interpolating the generated curves in the maturity dimension.
We obtain the algorithm of
N. Kahalé [An arbitrage-free interpolation of volatilities,

as a special case, when applying the Black–Scholes model as reference model.
Die 10 Modellannahmen der Computertomographie
Authors: Herold Frank 
Published: January 2020

Zusammenfassung
Die industrielle Computertomographie mittels Röntgenstrahlen (CT) wird oft als Referenz in der zerstörungsfreien Materialprüfung herangezogen wegen ihrer realitätsnahen dreidimensionalen Abbildungseigenschaften eines Prüfkörpers. Immer öfter wird die CT für Aufgaben der dimensionellen Meßtechnik herangezogen. Daher ist es wichtig zu hinterfragen, bis zu welchem Grad das Vertrauen in diese Technik gerechtfertigt ist.
In diesem Artikel werde ich 10 relevante Modellannahmen einführen und diese mit den für CT typischen Abbildungsartefakten in Verbindung bringen. Diese Artefakte beeinflußen die Genauigkeit der Abbildung und somit auch die davon abgeleiteten Meßgrößen sowie die bestmögliche Detailauflösung im Sinne einer Strukturauflösung.
Abschließend führe ich in den Stand der aktuellen Normung ein, um zu zeigen inwieweit es heute möglich ist, CT-Systeme vergleichend zu charakterisieren und somit auf die Eignung für eine spezielle Applikation rückschließen zu können.
Using an artificial neural network to evaluate the hull condition of naval vessels
Authors: Thiel Christian , Neumann Kevin , Broecheler Claas , Ludwar Frank , Rennings Andreas , Doose Jens , Erni Daniel 
Published: January 2020

Abstract
The evaluation of the hull condition of naval vessels is a crucial part for corrosion protection systems due to the direct linkage between the electrochemical process at the hull/water interface leading to corrosion and the overall coating of the hull to prevent the corrosion process. In the case of the latter, the condition is unknown while the vessel is on a mission and either has to be evaluated by divers (in open water) or on dry docks which is a time consuming process, respectively. In our work, we present a methodology to localize coating damages without the need of divers or dry docks using an artificial neural network (ANN) combined with the information provided by the onboard impressed current cathodic protection (ICCP) system to predict said damages in a specific sector of a generic ship model. Using only the ICCP currents as highly aggregated input variables for the ANN, approximately 86 % of randomly sized and positioned coating damages are correctly predicted.
Elektrische Kapazitätstomografie mit phantomabhängiger Adaptivität
Authors: Kandlbinder-Paret Christoph , Fischerauer Alice , Fischerauer Gerhard 
Published: January 2020

Zusammenfassung
In der elektrischen Kapazitätstomografie (ECT) verbessert sich die Auflösung der rekonstruierten Permittivitätsverteilung mit der Elektrodenanzahl, wohingegen die Anzahl der Kapazitätsmessungen und die Messzeit steigt und das Signal-Rausch-Verhältnis sinkt. Um einen Kompromiss zwischen Elektrodenanzahl und Auflösung zu finden, haben wir ein phantomabhängiges Adaptionsverfahren untersucht, in dem grobe Messungen mit verbundenen Einzelelektroden, die quasi synthetische größere Elektroden darstellen, durchgeführt werden. Das Verfahren wurde anhand eines Kunststoffzylinders im Erfassungsbereich im Inneren eines Rohres getestet. Wir vergleichen die rekonstruierten Ergebnisse basierend auf den Kapazitäten zwischen sechs synthetischen Elektroden und zwölf elementaren Elektroden sowie mit dem Adaptionsverfahren, das sowohl die Kapazitäten zwischen den sechs synthetischen Elektroden als auch zwischen einigen der elementaren Kapazitäten auswertet. Die Permittivitätsverteilung wird mit dem projizierten Landweber-Algorithmus einerseits aus berechneten Kapazitäten (Simulation mit der Finite-Elemente-Methode, FEM) und andererseits aus gemessenen Kapazitäten rekonstruiert. Die Kapazitäten werden dabei für jeweils zwei Fälle bestimmt. Im ersten Fall werden die Elektroden, die gerade nicht Teil der betrachteten Kapazität sind, geerdet, im zweiten Fall sind sie potentialfrei. Die Ergebnisse zeigen, dass im Erdungsfall die Rekonstruktionsergebnisse der gemessenen Kapazitäten mit dem Adaptionsverfahren sogar verbessert werden können. Im potentialfreien Fall und bei den Simulationen konnte das Phantom nur mit einer Verschlechterung der Auflösung dargestellt werden.

AbstractIsomorphicsymmetry reductions are a special class ofklassengleichesymmetry reductions where the subgroup has the same space group type. The present contribution highlights five differentisomorphictransitions of index 5 (i5), all fromI 4/mtoI 4/m. These superstructure formations allow (i) atom ordering in MoNi4, (ii) vacancy ordering in Nb4N5, KxFe2−ySe2and Nd10Au3As8O10and (iii) charge ordering in CsInCl3(≡Cs2InIInIIICl6). The group-subgroup schemes in the Bärnighausen formalism are discussed along with the crystal chemical consequences.

Gaucher hastalığı hepatosplenomegaliye neden olabilen bir lipid depo hastalığıdır. Zamanında tanı konamayan hastalarda ciddi splenomegaliye neden olabilmekte ve tanı alamamış hastalar gereksiz splenektomiye gidebilmektedir. Bu amaçla splenektomi yapılmış hastalar arasında zamanında tanısı konamamış, ancak splenektomi sonrası Gaucher hastalığı tanısı konmuş olanlar var mı diye araştırdık. 2010-2019 yılları arasında splenektomi yapılmış toplam 271 splenektomili hastanın klinikopatolojik ve demografik verileri geriye dönük olarak incelendi. Splenektomi yapılma sebeplerinden en sık üç sebep; travma (%26,5), solid organ tümörlerinin operasyonu esnasında (%22,88) ve immün trombositopenik purpura (%12,18) nedeniyleydi. Hastaların hiçbiri Gaucher hastalığından dolayı splenektomiye verilmemişti ve tanısal amaçlı splenektomi yapılmış olanların hiçbirinde Gaucher hastalığı saptanmamıştı. Gaucher hastalığında splenektomi , hematolojik ve mekanik problemler varken yapılabilmesine rağmen , artık selektif enzim replasman tedavisi tercih edilen tedavi şeklidir.
Trois modalités de réseaux littéraires pour enseigner la grammaire en contexte plurilingue
Authors: Thibeault Joël , Quevillon Lacasse Claude 
Published: January 2020

La grammaire est une discipline qui est ancrée dans la tradition scolaire francophone et dont l’enseignement, parce qu’on lui reconnait une fonction normative assumée, peut contribuer à la reproduction de certaines inégalités à l’école. Au regard de cet état de fait, le présent article veut, dans un premier temps, mettre en évidence la pertinence didactique que revêtent les réseaux littéraires pour l’enseignement de la grammaire du français (langue d’enseignement ou seconde) en contexte plurilingue. Ainsi exposerons-nous les fondements théoriques qui concourent à l’utilisation de ces réseaux et verrons-nous comment on peut les mettre en oeuvre afin de valoriser et de mettre à profit le répertoire linguistique pluriel des élèves. Dans un second temps, il s’agira d’exemplifier notre propos en présentant trois modalités de réseaux littéraires, ceux-ci, s’ils sont élaborés en considérant les plurilinguismes qui caractérisent de nos jours les salles de classe, pouvant soutenir le développement de la compétence grammaticale des élèves.

Translanguaging and the No Voice Policy in L2 Sign Language Contexts
Authors: Tanner Josée-Anna , Doré Nina 
Published: January 2020

This article draws on translanguaging theory and research to consider a common pedagogical practice in American Sign Language (ASL) as a second language (L2) classroom, the No Voice policy (i.e., spoken language use is forbidden). The No Voice policy serves important cultural and practical purposes, but by nature limits learners’ access to their entire linguistic repertoire, which raises questions about the overall impact of the policy on learners’ language development. Current literature about pedagogical translanguaging has not yet addressed practices that integrate (and, by extension, limit) selective modalities; we evaluate this gap and propose several directions for future research on the topic.Moreover, previous discussions of translanguaging practices involving recognized minority (e.g., Basque, Welsh, Irish) spoken languages are not wholly comparable to sign languages, which are not yet official or fully recognized languages in most countries and are therefore additionally vulnerable.We take into account the impact of ASL L2 learners on the language community, as many learners go on to become interpreters and allies to the deaf community.

Bridging Teaching, Learning and Assessment Processes through a Reflective Method: Implications for Plurilingual Learning Environments
Authors: Spinelli Barbara 
Published: January 2020

The challenges of global education highlight the need for students to meaningfully engage with their life experiences, deepen their reflection on their practices and feelings, and learn from them. What challenges may the implementation of such reflective approaches in a plurilingual and pluricultural learning environment entail? This article has a three-fold aim: first, it explores benefits that reflective and participatory methods have brought to plurilingual learners in different learning settings; second it describes the implementation of a three-mode reflective framework in a university blended course aimed at developing plurilingual competences, strategies, and literacies; and third, it argues how such reflective methods may contribute to promoting an integrated and transformative learning experience for a diverse linguistic and cultural learning community.

Translanguaging et intercompréhension - deux approches à la diversité linguistique ?
Authors: Schwender Philipp , Reissner Christina 
Published: January 2020

C’est la compétence plurilingue qui constitue l’un des objectifs centraux de la politique linguistique de l’Europe. Le translanguaging (TL) comme l’intercompréhension (IC) sont des conceptions proposées comme appropriées sur le chemin vers une diversité linguistique vécue. Les deux concepts se situent dans le champ de recherche en plurilinguisme comme approches positives à la diversité linguistique. Incontestablement, ils représentent un enrichissement dans le débat scientifique autour du plurilinguisme. Néanmoins, les frontières et interfaces entre TL et IC restent floues de sorte que la question d’une définition pertinente se pose généralement. À cet égard, la présente contribution se penchera sur la clarification des notions en question. L’objectif de cet article est donc de mettre en évidence quelques convergences et divergences épistémologiques entre les deux approches. Afin de compléter la perspective théorique, seront discutés quelques exemples d’une enquête menée à ce propos parmi des acteurs universitaires dans le domaine du plurilinguisme, les participants du Colloque du CCERBAL 2018.

Translanguaging, recours aux langues et aux cultures de la classe autour de la littérature de jeunesse pour des publics allophones d’Ottawa (Canada) et de Montpellier (France) : opportunités et défis pour la classe
Authors: Fleuret Carole , Auger Nathalie 
Published: January 2020

Bien que vivant un contexte sociolinguistique bien différent, l’Ontario au Canada et le Languedoc–Roussillon en France partagent de nombreux points communs (idéologie de défense de la langue française, impératif de reconnaître la diversité scolaire) utiles à une réflexion sur l’enseignement aux élèves migrants, population de plus en plus grandissante sur les deux bords de l’Atlantique, et au translanguaging. Le manque de formation concernant le répertoire plurilingue de l’élève, les approches plurielles et les activités translangagières dans l’appropriation du français nous ont incitées à choisir des albums de jeunesse comportant des aspects interculturels afin de proposer à des enseignants sur nos deux sites d’utiliser ces artefacts. Après avoir formé un certain nombre d’enseignants à la mise en oeuvre de l’interculturel et des albums de jeunesse en classe, nos résultats montrent que les enseignants ont des discours et attitudes contradictoires. Si l’album leur permet de s’autoriser et d’autoriser les langues et les cultures des élèves lors des séquences de classe, la majeure partie des activités translangagières proposées consistent à parler sur les langues et les cultures (sans inclure toutefois toujours celles des élèves) plutôt qu’à les utiliser comme une ressource à tout moment de la classe. Ces résultats nous amènent à proposer une redéfinition de la mise en oeuvre des approches plurielles et des pratiques translangagières qui soient traduisibles dans les futures formations des enseignants.

Enabling Translanguaging in the French Language Classroom
Authors: Weinmann Michiko , Charbonneau Noella 
Published: January 2020

Recent studies in multilingual and translanguaging pedagogies have shifted the focus from investigating how students engage their multilingual repertoires to exploring how teachers understand and implement these pedagogical directions in their practice. In this article, the authors report on a national online survey on the multilingual perspectives and practices of teachers of French in Australia. The overall goal of the survey discussed here was to comprehensively capture how teachers of French understand the teaching and learning of languages in general, and of French in particular. The study revealed several tensions between the language teachers’ beliefs and practice. While most of the survey participants expressed strong support for innovative pedagogies such as translanguaging (García & Wei, 2014), and keen motivation to engage the full multilingual repertoire of their learners, a closer reading of the data indicated that most of them felt restricted in their practice by “the normative terms and conditions of an understanding of languages education that remains rooted in parochial, monolingual and pecuniary perspectives” (Weinmann & Arber, 2017, p. 173). In particular, the findings indicate that (self-)perceptions of “non-native” language teachers as “culturally deficient” continue to frame the notion of what constitutes a “good” language teacher (Holliday, 2015). For teachers to feel more confident and better equipped to effectively implement translanguaging pedagogies in their practice, teachers’ perceptions of their own multilingual identities and how these are shaped within the systems they work in (Young, 2017) need to be better understood.

Translanguaging and Multilingual Texts as a Resource in Superdiverse Classrooms
Authors: Schwarzl Lena , Vetter Eva 
Published: January 2020

This contribution draws on the preliminary results of a project that uses translanguaging and plurilingual texts during an intervention (of six months) in one primary and one lower secondary school class in Vienna. Although Viennese pupils’ linguistic repertoires are highly diverse, pupils usually barely get a chance to use their respective repertoires at school, because of a focus on highly prestigious languages, such as German or English. We assumed that pupils would positively experience the use of their plurilingual competences to gain self-efficacy. Moreover, we expected that group dynamics would improve due to the use of translanguaging. Results of the ethnographic observations and interviews we conducted with one teacher at each school at the end of the intervention are discussed in this article. They support the conclusion that school classes that are linguistically diverse benefit from intervention at the socioemotional level. However, it is crucial that teachers pay particular attention to the integration of less dominant languages.

Published: January 2020

Social support can influence the perceptions of individual and social well-being for university students. We sought to verify whether the perceptions of social support correlate with the manifestation of clinical symptoms in young university students. A total of 26 participants, 58% female and 42% male, between the ages of 19 and 27 were included. The following tests were administered: SCL-90-R â€“ scale for the self-evaluation of general psychopathology and MSPSS â€“ self-assessment scale for the perception of social support. The students who perceived low levels of social support had high levels of clinical symptomatology (especially for internalised disorders). The index for a high intensity of symptoms Positive Symptom Total is correlated with a low level of perceived social support.

The effect of practical work to enhance ninth grade achievement in biology class: The case of diaspora secondary school, Ethiopia
Authors: Kelkay Asrat Dagnew , Sitotaw Chekula 
Published: January 2020

The aim of this study was to investigate the effects of practical work enriching instruction of biology lessons on ninth grade studentsâ€™ attitudes towards biology lessons and their achievement based on studentsâ€™ success. Attitude pre-test, attitude post-test, achievement pre-test and achievement post-test are employed for all participants in addition to interviewing four students randomly selected from the total participants. The test was applied to students in two different times. According to the research results, it was found that the experimental teaching method was more effective in the attitude and achievement level of students in some biology lessons, and attitude and achievement have a positive correlation. Therefore, the study recommends that high school biology teachers should plan their lessons in a more practical way to boost (enhance) learners' attitude as well as achievement. All stakeholders including curriculum planners should take part in the planning process.
Keywords: Achievement, attitude, effect, practical work, teaching method.
The factors of compassion fatigue among guidance counsellors
Authors: Estacio Rhenan Dizon 
Published: January 2020

The research was about the compassion fatigue and its contributing factors in guidance counsellors. The sample for the study was 92 guidance counsellors. This study explored factors of compassion fatigue, work-related factors, personality traits and demographic factors utilising the following instruments: professional quality of life scale (ProQOLs), NEO PI-R and demographic questionnaire. The context for the study was different schools in Central Luzon â€“ Region 3, Philippines. Descriptive statistics and multiple regression stepwise method were utilised in the study. Findings indicated that participants had low levels of burnout and low levels of secondary trauma stress as elements of compassion fatigue. Personality traits of the participants identified include low levels of neuroticism, average levels of extraversion, average levels of openness to experience, high level of agreeableness and high levels of conscientiousness. Multiple regression stepwise method confirmed that the personality traits neuroticism, extraversion and agreeableness predict burnout with a variability of 40%. Likewise, salary as work-related factor also predicts burnout with a variability of 4.7%. Similarly, personality trait neuroticism is confirmed to predict secondary trauma stress with a variability of 21.9%. Based on the two elements of compassion fatigue, neuroticism was found out to be the best predictor among the personality traits.
