MULTIPLICATION AND DIVISION OF FRACTIONS: NUMERICAL COGNITION DEVELOPMENT AND ASSESSMENT PROCEDURES
Authors: Díaz-Cardenas Alfonso F. , Díaz-Furlong Alfonso , Díaz-Furlong Hector Adrian , Sankey-García M. Rayo , Zago-Portillo Gemma
Published: November 2019

Number and its basic operations can be conceptualized within a general system of relationships. Children need to build a number system within which they can add, subtract, multiply, and divide any rational number. Products and quotients can be defined in terms of general relational schemes. In this study, we examine whether elementary school children can construct a number system such that multiplication and division of fractions are based on the construction of general relational schemata. Student groups are not homogeneous and children progress at different rates. For reliable assessment, teachers need methods to examine developmental and individual differences in cognitive representations of mathematical concepts and operations. A logistic regression curve offers a visualization of the learning process as a function of the average grades. Item analysis of multiplication and division of fractions shows an improvement in the probability of a correct answer, especially for students with a higher average score.
Aproximando-se da distância: as principais disparidades do pensamento fraco de Vattimo ante a ontologia heideggeriana
Authors: Debatin Gabriel
Published: November 2019

O presente ensaio pretende apresentar uma série de distanciamentos fundamentais entre o pensamento do italiano Gianni Vattimo, centrado no conceito de pensamento fraco, com a ontologia heideggeriana. A problemática consiste no confesso fato de Vattimo basear seu pensamento na filosofia de Heidegger; contudo, sob forte influência do pensamento de Nietzsche, o filósofo italiano acaba por desvirtuar certos conceitos cruciais da filosofia heideggeriana, conduzindo-a a conclusões diametralmente opostas às suas. Vattimo assevera, assim, que há um elemento niilista que perpassa toda a ontologia heideggeriana, não, contudo, apenas como um sintoma de uma sociedade decadente e indefinida, mas julga esta mesma ausência de sentido como a própria superação da metafísica tão almejada pela filosofia da história de Heidegger.
El debate sobre Plato und die Dichter y su inscripción en el contexto de Alemania Nacional-Socialista: una discusión con lecturas de la teoría política
Authors: Bey Facundo Norberto
Published: November 2019

Hans-Georg Gadamer, en su conferencia Plato und die Dichter (1934), desarrolló una investigación fenomenológica excepcional de filosofía ético-política de Platón y del lugar que el arte ocupa en ella. En mediados de la década de 1990, la escritora mexicana Teresa Orozco publicó una serie de escritos en los cuales acusa a Gadamer de haberse colocado, a través de la exhibición y publicación de este trabajo, a servicio del nacional-socialismo. Este artículo busca discutir los argumentos presentados por Orozco y otros autores, en primer lugar, investigando la heterogeneidad de la recepción del texto en cuestión entre 1934 y 1944, dentro y fuera de Alemania; en segundo lugar, recuperando datos biográficos relevantes que fueron omitidos por sus detractores; y, finalmente, ofreciendo pruebas documentales que refuten los fundamentos de la acusación mencionada anteriormente. Al final, haré una propuesta de lectura metodológica para analizar el trabajo de referencia en relación a su contexto histórico, lo que puede contribuir para verificar en qué sentido esta conferencia expresaría la disidencia de Gadamer con la hegemonía Nacional-Socialista.
Computational wear prediction of insert conformity and material on mobile-bearing unicompartmental knee arthroplasty
Authors: Koh Yong-Gon , Lee Jin-Ah , Lee Hwa-Yong , Kim Hyo-Jeong , Kang Kyoung-Tak
Published: November 2019

Objectives

Unicompartmental knee arthroplasty (UKA) is an alternative to total knee arthroplasty with isolated medial or lateral compartment osteoarthritis. However, polyethylene wear can significantly reduce the lifespan of UKA. Different bearing designs and materials for UKA have been developed to change the rate of polyethylene wear. Therefore, the objective of this study is to investigate the effect of insert conformity and material on the predicted wear in mobile-bearing UKA using a previously developed computational wear method.

Methods

Two different designs were tested with the same femoral component under identical kinematic input: anatomy mimetic design (AMD) and conforming design inserts with different conformity levels. The insert materials were standard or crosslinked ultra-high-molecular-weight polyethylene (UHMWPE). We evaluated the contact pressure, contact area, wear rate, wear depth, and volumetric wear under gait cycle loading conditions.

Results

Conforming design inserts had the lower contact pressure and larger contact area. However, they also had the higher wear rate and volumetric wear. The improved wear performance was found with AMD inserts. In addition, the computationally predicted volumetric wear of crosslinked UHMWPE inserts was less than half that of standard UHMWPE inserts.

Conclusion

Our results showed that increasing conformity may not be the sole predictor of wear performance; highly crosslinked mobile-bearing polyethylene inserts can also provide improvement in wear performance. These results provide improvements in design and materials to reduce wear in mobile-bearing UKA. Cite this article: Bone Joint Res 2019;8:563–569.

Can ›epistemic silence‹ be decolonised?
Authors: Darowska Lucyna
Published: November 2019

Lucyna Darowska geht in ihrem Beitrag der Frage nach, inwiefern die Wissensproduktion an den Universitäten in Deutschland in bestimmten Themenfeldern von tradierten Perspektiven eingegrenzt ist. Sie nimmt zuerst die globalen ökonomischen und politischen Verhältnisse in den Blick und legt aus einer kritisch-analytischen Perspektive die Mechanismen der Ungleichheitsherstellung zum Nachteil des »globalen Südens« offen. Zugleich konstatiert sie eine marginale Relevanz dieses Themas an den Hochschulen. Kritische Theorieanalyse stellt darüber hinaus den zukunftsweisenden Gehalt der Marx'schen Theorie, die vielerorts zur Kritik neokolonialer Zustände herangezogen wird, auf den Prüfstein. Es wird eine Kontinuitätslinie zwischen der in vieler Hinsicht unzulänglichen Marx'schen Theorie und der tragischen Entwicklung der diktatorischen quasikolonialen Zustände in osteuropäischen Ländern (1945-1989) nachgezeichnet. Ein reflektierendes dekolonialisierendes Paradigma wird in Bezug auf beide »Leerstellen« gefordert, dessen Notwendigkeit exemplarisch auch am Ausschnitt aus feministischen Diskursen gezeigt wird.

Die Studie zeigt: Die Kombinationsmöglichkeiten der Beziehungen zwischen den Produktionsnetzwerken bieten vielfältige Perspektiven - insbesondere für kleine und mittelgroße Unternehmen, die die Berliner Modebranche bevölkern.
Die Polemik der Restauration
Authors: Kruska Alexander
Published: November 2019

Auf die Französische Revolution folgte eine Epoche der »Restauration«: Die europäische Politik Anfang des 19. Jahrhunderts wollte die vorrevolutionäre Ordnung des Ancien Régime wiederherstellen. Der Autodidakt Karl Ludwig von Haller verfasste die Schrift »Restauration der Staatswissenschaft«, deren unverhohlener wie wohlüberlegter Kampfgeist dem Leser von der ersten Seite an entgegenschlägt. Alexander Kruska zeigt, inwiefern von Hallers aufsehenerregender erster Band der Restaurationsschrift als eine politiktheoretisch motivierte, systematische Polemik zu verstehen ist. Im Bestreben, dem Fragen nach legitimer Herrschaft ein Ende zu bereiten, setzt von Haller dem aufklärerischen Staatsdenken eine »bessere Doktrin« entgegen: Anstatt vernunftbegründeter Staatlichkeit proklamiert er eine natürliche Ordnung bloßer Machtverhältnisse. Zu diesem Zweck gilt es, gegen das politische Denken selbst vorzugehen.

Science Slam
Authors: Stimm Maria
Published: November 2019

Vielfältige Formen der Wissenschaftskommunikation haben sich etabliert - darunter der ›Science Slam‹ als ein Format, welches aktuelle Ansprüche an den Bereich der Wissenschaftskommunikation abbildet. Als Forschungsgegenstand dient es Maria Stimm dazu, zwei bisher eher für sich stehende Bereiche zu verschränken: Wissenschaftskommunikation und Erwachsenenbildung. Die Studie arbeitet die zentrale Bedeutung heraus, die die Begegnung von Wissensstrukturen für die Wissenschaftskommunikation hat, und stellt das Konzept der Lernkulturen vor, welches eine didaktische Positionsbeschreibung des Veranstaltungsformats für die Erwachsenenbildung bietet. Die spezifische Lernkultur des ›Science Slam‹ wird dabei analytisch über den innovativen Ansatz des ›Da-Zwischen‹ herausgearbeitet.
Big Science Fiction - Kernfusion und Popkultur in den USA
Authors: Märkl Simon
Published: November 2019

Die Kernfusion, die in Wasserstoffbomben seit 1954 auf zerstörerische Weise gelingt, zur Stromerzeugung nutzbar zu machen, ist eines der ambitioniertesten Großforschungsprojekte seit dem Manhattan-Projekt. Ihre Geschichte als Zukunftstechnologie im Spiegel öffentlicher Darstellungen illustriert das wechselvolle Verhältnis der amerikanischen Gesellschaft zu den Zielen und der Richtung technologischer Entwicklung. Simon Märkl macht deutlich, dass die Kernfusion als Gegenstand medialer und kultureller Auseinandersetzung dabei zu allen Zeiten nicht nur eine neue Möglichkeit umweltfreundlicher Energieversorgung, sondern immer auch Mittel zur Propagierung politischer Werte und Vorstellungen war.
Die USA und ihre Bösen
Authors: Butter Stefan
Published: November 2019

Spielfilme sind nicht nur ein populäres Unterhaltungsmedium, sie transportieren auch Konzepte und Werte der Gesellschaften, in denen sie produziert werden. Dazu gehören nicht zuletzt Vorstellungen vom »Bösen« - Feindbilder, ohne die keine Kultur auskommt. Die Geschichtswissenschaft hat dem bislang nur wenig Aufmerksamkeit geschenkt. In der ersten umfassenden Studie zu diesem Thema untersucht Stefan Butter den Feindbildwandel in den USA in jenen Jahrzehnten, in denen der Kalte Krieg zu Ende ging und der »Krieg gegen den Terror« begann und damit entscheidende Weichen für die Welt gestellt wurden, in der wir heute leben.
Die Korrektur der Gesellschaft
Authors: Mölders Marc
Published: November 2019

Über Gesellschaft lässt sich viel lernen, wenn man die Arbeit an ihrer Korrektur untersucht. Globalisierung und Digitalisierung scheinen Korrektiven abseits des Staatlichen eine Sonderposition einzuräumen: Ungekannt schnell und grenzenlos können sie operieren. Marc Mölders zeigt, dass zentrale Gesellschaftsprobleme Übersetzungskonflikte sind und dies nicht nur differenzierungstheoretisch angenommen wird. Anhand des Investigativ-Journalismus - einer Form organisierter Gesellschaftskorrektur - zeichnet er nach, wie eine durch Tempo-Dosierung und Grenzeinhaltung gekennzeichnete Irritationsgestaltung aus Publikationen »Druckerzeugnisse« macht.
História da disciplina escolar Língua Portuguesa em Mato Grosso do Sul (1977-2008)
Authors: Sperandio Daniele Spadotto
Published: November 2019

A obra “História da Disciplina Escolar Língua Portuguesa em Mato Grosso do Sul (1977-2008) é resultado de uma pesquisa de pós-doutoramento em Educação Escolar pela Universidade Estadual Paulista Júlio de Mesquita Filho, defendida em 2011, e está fundamentada em rigorosa pesquisa histórica documental, com uma criteriosa análise sobre as políticas curriculares da Língua Portuguesa referente ao período de 1977 a 2008, permeando as transformações ocorridas no ensino dessa disciplina no Estado de Mato Grosso do Sul. A autora observou a ausência de estudos que abordam a compreensão do passado mais recente, em especial a partir de 1970, de modo que, para delimitação temporal, registra o período de criação do estado de Mato Grosso do Sul, em 1977 até 2008, quando constava a proposta curricular vigente no momento da coleta de dados, e para delimitação do corpus, a análise refere-se as quatro últimas séries/ano do 1º grau/ensino fundamental. A autora baseou-se na configuração textual para a análise das propostas curriculares como documento escrito e que abrange uma série de aspectos compreendidos como elementos constitutivos desse documento, independentes se externos ou internos, a saber: quem escreveu, onde, quando, por que, o quê, para quê, para quem e como. Dessa maneira, as propostas curriculares passaram por uma análise sobre a materialidade de seus suportes, compreendendo os aspectos formais das propostas, a autoria, a recepção, as concepções teóricas e as bibliografias consultadas e sugeridas.

O espectro da anormalidade ronda os alunos
Authors: Catani Júlia
Published: November 2019

Em A "'criança-problema" na escola brasileira - uma análise do discurso pedagógico, Ana Laura Godinho Lima examina de forma detalhada o que seria este modo de nomeação e suas possíveis repercussões no campo educacional brasileiro. O material analisado na obra que é fruto da tese de doutoramento mostra a necessidade de se remontar à origem dos termos, dos nomes e dos recursos verbais empregados no cotidiano escolar. A pesquisadora desenvolve uma extensa investigação a respeito dos elementos envolvidos na classificação de “criança-problema”. Aos leitores apressados, desejosos de rápido esclarecimento do que envolve o cenário do uso dos termos, recomendo paciência, pois a atenção detida ao modo de organização do trabalho de análise nos permite apreciar, como num roteiro de viagem, cada escolha feita pela autora e o modo de construção da crítica a cada um dos problemas identificados. Ou seja, o leitor é recompensado pelas informações contidas em cada página, informações estas que se estendem para muito além do volume de dados e ensejam reflexões e questionamentos férteis para a compreensão das práticas educacionais e também para os campos do conhecimento pedagógico e do cuidado em geral. Já dizia Freud: quanto mais se souber do passado, melhor serão as possibilidades de futuro. Conhecer a história que levou à identificação e nomeação da criança-problema permite entender fatores sociais, escolares, religiosas e familiares envolvidos na situação e nos alerta para o que pode não ser evidente ou até mesmo ser desconhecido por nós.
ATPASE ERYTHROCYTE TRANSPORT SYSTEMS IN HUMAN BLOOD
Authors: Fedorova E , Nalobina A , Sizov A
Published: November 2019

Aim. The article deals with establishing the features of ATPase erythrocytes in the athletes of the first and second categories and non-athletes from different age groups. Material and methods. We studied the capillary blood of track-and-field athletes and healthy non-athletes of the same age and anthropometric characteristics (n = 60). Blood analysis was performed with the help of the Dixion hematological analyzer (Russia). The activity of erythrocyte membrane ATPases was studied according to K.S. Keeton. Results. The study revealed significant (p < 0.05) differences in certain (HGB and RBC) hematological blood indicators in participants from different age groups depending on their physical fitness. Age differences between groups are not significant (p > 0.05). The results obtained demonstrate the significantly (p < 0.001) higher values of ATPase activity in the athletes of the first and second categories from various age groups. The increase in Mg2+, Na+, K+-, Mg2+- and Na+, K+-ATPases activity in athletes is connected with more intensive metabolism in this group because transport ATPases participate in the energy supply of training and competition loads. Age-related differences (p < 0.05) in the activity of erythrocyte membrane ATPases in both groups can be possibly connected with the conformation features of erythrocyte membrane protein. The two-factor dispersion analysis revealed that age significantly (Р < 0.001) determined Mg2+, Na+, K+-, Mg2+- and Na+, K+-ATPases erythrocyte membrane activity at 89.15, 87.46, and 81.40 % respectively; physical activity at 96.19, 95.45 and 93.80 % respectively. Conclusion. General physical fitness and age can be considered as the factors determining the activity of erythrocyte membrane ATPases.
FUNCTIONAL STATUS OF THE CHILDREN WITH REGULAR PHYSICAL ACTIVITY
Authors: Zhigalo V , Litvin F , Bulavkina T , Dubogryzova I , Stanishevskaya T
Published: November 2019

Aim. The article deals with studying the dynamics of a functional status in young football players aged 10–11 based on the typological features of vegetative heart rhythm regulation and individual reactivity to physical load. Materials and Methods. 28 boys regularly attending a football section participated in the study. We studied the dynamics of their functional status by using the mathematical analysis of heart rate data. HRV data were processed and interpreted with the help of the ‘Varicard 2.51’ equipment and ‘Eskim-6’ program (Axion). The study was conducted at the beginning and at the end of the training year. All participants belonged to the 2nd year group of initial preparation. Results. We revealed three of four existing types of vegetative heart rhythm regulation. More than half of children are characterized by a moderate or pronounced predominance of the central regulatory mechanism. It is shown that after a four-month training in the football section, the number of children with a moderate predominance of the autonomous regulatory mechanism is increasing. We registered a significant increase in the parameters reflecting the activity of the parasympathetic nervous system. For example, RMSSD increases by 71% (р < 0.05), HF by 116% (р < 0.05). The decrease of tension in regulatory systems is proved by an increase in the total power (TP) by 35 % and a decrease in the Stress Index (SI) by 62 % (р < 0.05). We also registered a simultaneous decrease in the number of football players with the predominance of the central regulatory mechanism. Conclusion. We revealed increased resistivity to physical load in young football players with the predominance of autonomous regulation. We demonstrated the need for an individual approach to adjusting physical load concerning the genetic predisposition of heart regulation.

Published: November 2019

Aim. The article deals with improving the efficiency of ball throwing technique enhancement in basketball beginners. Materials and methods. 2 groups (10 persons each group, control and experimental) of male basketball beginners born in 2007–2009 participated in the study. The training was conducted at the premises of “Yugoria” Olympic reserve school named after A. Piloyan (Surgut, Russia). For an objective instrumental assessment of the 3rd stage of training, we used “Stabilo-MBN” computer-assisted stabilometry. Results. Statistically significant positive changes in muscle synergy and kinesthetic sensitivity in the experimental group reflect the objectively significant improvement of throwing accuracy under standard test conditions. Conclusion. The fundamental rules of the performance of the mechanisms in the nervous system allowed us to objectively improve the efficiency of ball throwing technique enhancement in basketball beginners.

Designing tasks for developing complex language skills and cognitive
competence in the distance learning of Slovak as a foreign language
Authors: Mošaťová Michaela , Výškrabková Jana
Published: November 2019

The Slovak language is one of the less commonly taught languages, and
its learners worldwide have few options in terms of its study and practice.
One of them, however, is the www.e-slovak.sk e-learning platform provided by
the Studia Academica Slovaca Centre at the Comenius University Faculty of
Arts in Bratislava, Slovakia. This article summarises a two year experience
teaching Slovak in two tutored e-learning courses of e-slovak levels A1 and
A2 (CEFR, 2001). The article focusses mainly on the tasks contributing to
the development of productive communication skills (speaking and writing).
We explored to what extent various language learning tasks are efficient in
terms of developing complex language skills and engaging students’ cognitive
skills in accordance with Anderson et al.’s (2001) revised Bloom’s taxonomy
of teaching objectives.
An iCALL approach to morphophonemic training for Irish using speech
technology
Authors: Ní Chiaráin Neasa , Ní Chasaide Ailbhe
Published: November 2019

A key benefit in intelligent Computer Assisted Language Learning (iCALL)
is that it allows complex linguistic phenomena to be incorporated into
digital learning platforms, either for the autonomous learner or to
complement classroom teaching. The present paper describes (1) complex
phonological/morphophonemic alternations of Irish, which are problematic for
many learners; (2) an iCALL platform, An Scéalaí, which uses speech
technology and Natural Language Processing (NLP) prompts to train writing
and aural skills – in this paper the target is the morphophonemic
alternations of (1); and (3) a perception experiment to guide how the
platform might be used for prompt-based self-correction. The perception
experiment has been carried out using newly built synthetic voices based on
deep neural network technology.
Time to evaluate: the students’ perspective of an online MA in CALL
programme
Authors: Papadima-Sophocleous Salomi , Giannikas Christina Nicole
Published: November 2019

Despite the critical importance of Computer Assisted Language Learning
(CALL) Teacher Education (CTE) programmes, L2 practitioners often report
that there are not many such onsite/online programmes, and the ones that
exist may not directly meet their specific needs. Moreover, there seems to
be a lack of systematic evaluation studies of such courses. As a result,
problems in such courses cannot be diagnosed, and they are left unresolved.
This paper presents a study undertaken to evaluate an online Master’s of
Arts (MA) in CALL programme in the Republic of Cyprus. The investigation was
based on a conceptual multidimensional e-learning evaluation model rated by
the students. Data were collected from 25 graduate students via an online
anonymous survey. This focussed on the participants’ perceptions of the
value of the following aspects: (1) their engagement; (2) the course and its
organisation, teaching mode, and materials; (3) course strengths; (4) course
aspects most helpful to learning; and (5) course aspects which were
obstacles to learning. This paper discusses the findings and offers some
first recommendations for further improvement to the MA in CALL
programme.
Joining the blocks together – an NLP pipeline for CALL
development
Authors: Ward Monica
Published: November 2019

Intelligent Computer-Assisted Language Learning (ICALL) involves using
tools and techniques from computational linguistics and Natural Language
Processing (NLP) in the language learning process. It is an inherently
complex endeavour and is multi-, inter-, and trans-disciplinary in nature.
Often these tools and techniques are designed for tasks and purposes other
than language learning, and this makes their adaptation and use in the CALL
domain difficult. It can be even more challenging for Less-Resourced
Languages (LRLs) for CALL researchers to adapt or incorporate NLP into CALL
artefacts. This paper reports on how two existing NLP resources for Irish, a
morphological analyser and a parser, were used to develop an app for Irish.
The app, Irish Word Bricks (IWB), was adapted from an existing CALL app –
Word Bricks (Mozgovoy & Efimov, 2013). Without this ‘joining the blocks
together’ approach, the development of the IWB app would certainly have
taken longer, may not have been as efficient or effective, and may not even
have been accomplished at all.

The theme selected for the 2019 EuroCALL conference held in
Louvain-la-Neuve was ‘CALL and complexity’. We decided to opt for a positive
vision of complexity. As languages are known to be linguistically complex,
as are the many determinants of learning (additional) languages, we wanted
to view complexity as a challenge to be embraced collectively. The 2019
conference allowed us to pay tribute to providers of Computer Assisted
Language Learning (CALL) solutions and to recognize the complexity of their
task, to acknowledge the notion of complexity to ensure the provision of ad
hoc CALL solutions, and to draw both learners’ and teachers’ attention to
complexity issues so that they can make the most of their learning/teaching
experience.

This research project investigates mobile literacy of Syrian refugee
women teachers settled in Lebanon and Sweden. Our research provides input
into Syrian refugee women teachers’ professional aspirations and their
connection to informal mobile learning. In both countries, training programs
are used for these newly arrived teachers, enabling them to move forward in
their careers, where digital and mobile learning play an important part. The
purpose is to investigate how Syrian refugee women teachers are blending
their teaching profession and vocational training with mobile literacy and
digital technology. A qualitative method approach was applied, interviewing
20 refugee women in Lebanon and Sweden, all teachers from Syria. The
outcomes show that the teachers are developing their vocational abilities in
getting more career-oriented training in their areas of education by means
of enhancing their language skills through mobile technology.
English -learning mobile app designing for engineering students’ cross-disciplinary learning and collaboration
Authors: Tai Yaming , Ting Yu-Liang
Published: November 2019

Engineers must be able to collaborate with experts across disciplinary boundaries to successfully address the complex challenges of a contemporary workplace. The related training and research on motivating and engaging engineering students in schools is limited and rarely accounts for students’ lived experiences in the curriculum design. Meanwhile, programming is a medium of communication that can be reflexive with other domains and has been treated as a way of thinking about and exploring disciplines beyond computer science. In this study, engineering students used authoring tools of mobile app to design an English-learning app, in which English teachers provide feedbacks for revision, and a preliminary cross-disciplinary collaboration is asserted. The learning design referred to the frameworks of constructing socio-technical creativity to aid the students in employing their existing English knowledge to design mobile apps. The evaluation was conducted on the basis of the students’ designed apps and presentation, teachers’ feedback, and students’ self-reports. The results indicated that the common use of mobile apps in people daily life seemed to create a boundary object for the engineering students and English teachers to express, communicate, and coordinate their perspectives and knowledge. Students could view the engineering work from different aspects and appreciate English teachers’ comments and value their expertise. By accounting for the interests of students and schools’ limited resources, this study serves as a reference for cross-disciplinary learning and collaboration methodology.
The effectiveness of the choice of criteria on the stationary and non-stationary noise removal in the phonocardiogram (PCG) signal using discrete wavelet transform
Authors: Rouis Mohamed , Sbaa Salim , Benhassine Nasser Edinne
Published: November 2019

The greatest problem with recording heart sounds is parasitic noise effects. A reasonable solution to reduce noise can be carried out by minimization of extraneous noises in the vicinity of the patient during recording, in addition to the methods of signal processing that must be effective in noisy environments. Wavelet transform has become an essential tool for many applications, but its effectiveness is influenced by main parameters. Determination of mother wavelet function and decomposition level (DL) are important key factors to demonstrate the advantages of wavelet denoising. So, selection of optimal mother wavelet with DL is a main challenge to current algorithms. The principal aim of this study was the choice of an appropriate criterion for finding the optimal DL and the optimal mother wavelet function according to four criteria which are: signal-to-noise ratio (SNR), mean square error (MSE), percentage root-mean-square difference (PRD) and the structure similarity index measure (SSIM) for testing the robustness of the proposed algorithm. The proposed method is applied to the PCG signal contaminated with four colored noise types, in addition to the Gaussian noise. The obtained results show the effectiveness of the proposed method in reducing noise from the noisy PCG signals, especially at a low SNR.
Kyararevisited: The pre-narrative character-state of Japanese character theory
Authors: Wilde Lukas R.A.
Published: November 2019

This article proposes to take a closer look at a variety of contemporary Japanese “character” franchises which cannot be accounted for if the entities in question are primarily understood with reference to diegetic worlds or stories. Rather, virtual idols like Hatsune Miku, fictional mascots like Kumamon, or notorious product placement figures such as Hello Kitty all seem to circulate mostly on non-narrative artifacts such as clothes, office supplies, or decontextualized artworks, and within mediated performances such as stage musicals, cosplay, or public appearances in full-body suits. They are nevertheless quite typical for the Japanese “media mix” franchising model, designed to allow for user-level reshuffling and reenactment. Such “characters without stories,” orkyara,are thus best understood as “mediated performers,” as fictional actors that can take on any fictional role attributed to them within the participatory cultures and collective creations of fan manga (dōjinshi), fan artworks, or even cosplay. Theorists such as Itō (2005) or Azuma (2009) therefore differentiate sharply betweenkyarakutāundkyara,the latter being a pre- or meta-narrative “nodal point” for diverging games of make-believe.Kyaracan just as easily beenactedandperformedas they can be brought back into narrative (kyarakutā) contexts. The following article relates and contrast these notions to international (“Western”) character theories and argues for their relevance beyond “exotic” Japanese contexts.
The stimulation protocol in poor responder IVF; a minimal or high-dose stimulation? – A meta-analysis
Authors: Jamaludin Ridzuan , Ahmad Mohd Faizal , Park Dae-Keun , Zain Murizah Mohd , Yoon Tae-Ki , Lee Woo-Sik , Koong Mi Kyoung , Lee Kyung-Ah
Published: November 2019

Background

To determine whether a minimal stimulation (MS) or high-dose stimulation (HDS) protocol is a better option for patients classified as poor ovarian responders (POR) in terms of reproductive and pregnancy outcomes.

Materials and methods

A database search for evaluation of the study outcome by using meta-analysis method was carried out. The primary outcome was the clinical pregnancy (CP) rate for each of two groups, namely, the MS and HDS groups. The secondary outcomes were the gonadotropin dose used, duration of stimulation, cancellation rate, number of oocytes retrieved, number of fertilized oocytes, number of embryos transferred and live birth rates.

Results

Across five databases, 4670 potential studies for further screening were selected. But ultimately only six studies, three RCTs and three retrospective or case control studies were selected that meet the Bologna criteria for POR. In all there were 624 cycles. Our meta-analysis indicated that the CP rates, cycle cancellation rates, durations of stimulation, numbers of oocytes fertilized and numbers of embryos transferred were not statistically significant. Clearly, the number of oocytes retrieved in the MS group was significantly lower than in the HDS group, while the HDS group consumed significantly higher doses of gonadotropins than the MS group. The live birth rates were significantly higher in the MS group than in the HDS group.

Conclusion

MS should be the first-line protocol for managing POR because the live birth rate is significantly higher, even with fewer oocytes retrieved.

Blast furnace heat is the key to the blast furnace’s high efficiency and stable operation, and it is difficult to maintain a suitable temperature for large blast furnace operations. When designing the furnace heat prediction and control model, parameters with good reliability and measurability should be chosen to avoid using less accurate parameters and to ensure the accuracy and practicability of the model. This paper presents an effective model for large blast furnace temperature prediction and control. Using thermal equilibrium and the carbon-oxygen balance of the blast furnace’s high-temperature zone, the slag-iron heat index was calculated. Using the relation between the molten iron temperature and slag-iron heat index, the furnace heat parameter can be calculated while production conditions are changed,which can guide furnace heat control.
Back from the Future: Divine Supercomprehension and Middle Knowledge as Ground for Retroactive Ontology
Authors: Hollingsworth Andrew
Published: November 2019

In this article, I attempt to solve a problem in Wolfhart Pannenberg’s eschatology, which is best understood as a retroactive ontology. Pannenberg argues that the future exerts a retroactive causal and determinative power over the present, though he also claims that said future does not yet concretely exist. The problem can be posed thus: How does a non-concrete future hold retroactive power over the concrete present? I argue that the doctrines of middle knowledge and supercomprehension formulated by the Spanish Jesuit theologian Luis de Molina, provide an adequate solution to this problem while still preserving both the retroactive power of the nonconcrete future as well as genuine human libertarian free choice.
A surprising mechanism lacking the Ni(0) state during the Ni(II)-catalyzed P–C cross-coupling reaction performed in the absence of a reducing agent – An experimental and a theoretical study

The Hirao reaction, i.e. the P–C coupling between a bromoarene and a >P(O)H reagent performed in most cases in the presence of a Pd(0) complex incorporating a P-ligand may also be carried out applying a Ni(II) catalyst precursor with or without Zn or Mg as the reducing agent. The Ni catalysts may include P- or N-ligands. B3LYP/6-31G(d,p)//PCM(MeCN) quantum chemical calculations suggested that the mechanism of the NiX2 catalyzed (X=Cl or Br) P–C couplings performed in the absence of a reducing agent, and in the excess of the >P(O)H reagent serving as the P-ligand (via its tautomeric >POH form) is completely different from that of the Pd(OAc)2 promoted version, as no reduction of the Ni(II) occurs. In the two variations mentioned, the active catalyst is the dehydrobrominated species derived from primary complex [(HO)Y2P]2Ni(II)Br2, and the [(HO)Y2P]2Pd(0) complex itself, respectively. Both species undergo temporary oxidation (to “Ni(IV)” and “Pd(II)”, respectively) in the catalytic cycle. During the catalysis with “P2Ni(II)X2”, one of the P-ligands serves the >P(O)H function of the ArP(O)H <  product. The consequence of this difference is that in the Ni(II)-catalyzed case, somewhat less >P(O)H-species is needed than in the Pd(0)-promoted instance. Applying 10 % of the Pd(OAc)2 or NiX2 precursor, the optimum quantity of the P-reagent is 1.3 equivalent and, in the first approach, 1.1 equivalent, respectively. Preparative experiments justified the new mechanism explored. The ligation of Ni(II) was also investigated by theoretical calculations. It was proved that the bis-complexation is the most favorable energetically as compared to the mono-, tri- and tetra-ligation.
Inverse approach for concentrated winding surface permanent magnet synchronous machines noiseless design

Published: November 2019

The electromagnetic noise generated by the Maxwell radial pressure is a well-known consequence. In this paper, we present an analytical tool that allows air gap spatio-temporal pressures to be obtained from the radial flux density created by surface permanent magnet synchronous machines with concentrated winding (SPMSM). This tool based on winding function, a global air-gap permeance analytical model and total magnetomotive force product, determines the analytical air-gap spatio temporal and spectral radial pressure.We will see step-by-step their impacts in generating noise process. Also two predictive methods will be presented to determine the origin of the lows radial pressure orders noise sources. The interest lies in keeping results very quickly and appropriate in order to identify the low order electromagnetic noise origin. Then through an inverse approach using an iterative loop a new winding function is proposed in order to minimize radial force low order previously identified and chosen.
The Institutional Dimension of Class-based Educational Decision-making: Evidence from Regional Variation in Switzerland
Authors: Combet Benita
Published: November 2019

This article examines to what extent the specific institutional arrangement of an education system moderates the influence of social background on students’ track allocation, and whether this happens via primary or secondary effects of social origin. I tackle the problem of omitted-variable bias by analyzing subnational education systems in Switzerland, a country with a variety of cantonal school systems but otherwise homogeneous institutions. The results show a complex picture. First, even though the absolute transition probability to the highest track is higher in education systems with low stratification for students of higher social background, this does not translate into a relative advantage as in most cantons the odds of transitioning do not differ between high and low social background students. Second, in line with previous research, I observe that the secondary effect of social origin prevails in more stratified education systems. Third, it is not possible to conclude with certainty that specific features of the education system enable high social background parents to disproportionately influence their children’s transition probabilities because the results are not robust.
Zwischen affirmativer Teilnehmer- und kritischer Beobachterperspektive

Dieser Kommentar nimmt eine Studie von Stefan Hirschauer über die Entstehung von geschlechtlichen Asymmetrien in der Schwangerschaft zum Anlass, um über die soziologische Form der Thematisierung von Symmetrien und Asymmetrien nachzudenken. In der genannten Studie wird in analytischer Absicht der moderne Kampf um symmetrische Anteile in der Elternschaft eindrücklich dargestellt, zugleich verstrickt er sich aber selbst in diesen Kampf, indem er sich für eine Symmetrisierung der (Vor-)Elternschaft engagiert. Der Beitrag changiert also zwischen kritischer Beobachtungs- und affirmativer Teilnehmerperspektive. Er weiß also schon stets, welche Lösung die bessere sei. Über eine solche affirmative Teilnehmerperspektive möchte der Kommentar hinausführen, indem er auf die „Kulturbedeutung“ (Weber) von modernen Symmetriepostulaten hinweist und zu einer kritischen Beobachtung des Umgangs mit Differenzen (Luhmann, Foucault) auffordert.

The reactions of the binary metal chlorides AgCl, RbCl and PbCl2 at T = 180°C in the ionic liquid [BMIm]Cl · 4AlCl3 (BMIm = 1-n-butyl-3-methylimidazolium) yielded air-sensitive, colorless, high-quality crystals of their tetrachloridoaluminate(III) salts. Thereby, the obstructions that hinder proper crystallization of these compounds from pristine AlCl3 melts were circumvented. X-ray diffraction on single-crystals revealed a monoclinic structure (space group P21/c) for Ag[AlCl4], which unexpectedly has a closer relation to Cu[AlCl4]2 than to Cu[AlCl4]. Rb[AlCl4] crystallizes in the baryte structure type (orthorhombic, Pnma), and Pb[AlCl4]2 is isotypic to α-Sr[GaCl4]2 (orthorhombic, Pbca).

TMEM16A, a Ca2+‐activated Cl− channel, is known to modulate the excitability of various types of cells; however, its function in central neurons is largely unknown. Here, we show the specific expression of TMEM16A in the medial habenula (mHb) via RNAscope in situ hybridization, immunohistochemistry, and electrophysiology. When TMEM16A is ablated in the mHb cholinergic neurons (TMEM16A cKO mice), the slope of after‐hyperpolarization of spontaneous action potentials decreases and the firing frequency is reduced. Reduced mHb activity also decreases the activity of the interpeduncular nucleus (IPN). Moreover, TMEM16A cKO mice display anxiogenic behaviors and deficits in social interaction without despair‐like phenotypes or cognitive dysfunctions. Finally, chemogenetic inhibition of mHb cholinergic neurons using the DREADD (Designer Receptors Exclusively Activated by Designer Drugs) approach reveals similar behavioral phenotypes to those of TMEM16A cKO mice. We conclude that TMEM16A plays a key role in anxiety‐related behaviors regulated by mHb cholinergic neurons and could be a potential therapeutic target against anxiety‐related disorders.

Accumulating evidence highlights the role of histone acetyltransferase GCN5 in the regulation of cell metabolism in metazoans. Here, we report that GCN5 is a negative regulator of autophagy, a lysosome‐dependent catabolic mechanism. In animal cells andDrosophila, GCN5 inhibits the biogenesis of autophagosomes and lysosomes by targeting TFEB, the master transcription factor for autophagy‐ and lysosome‐related gene expression. We show that GCN5 is a specific TFEB acetyltransferase, and acetylation by GCN5 results in the decrease in TFEB transcriptional activity. Induction of autophagy inactivates GCN5, accompanied by reduced TFEB acetylation and increased lysosome formation. We further demonstrate that acetylation at K274 and K279 disrupts the dimerization of TFEB and the binding of TFEB to its target gene promoters. In a Tau‐based neurodegenerativeDrosophilamodel, deletion of dGcn5 improves the clearance of Tau protein aggregates and ameliorates the neurodegenerative phenotypes. Together, our results reveal GCN5 as a novel conserved TFEB regulator, and the regulatory mechanisms may be involved in autophagy‐ and lysosome‐related physiological and pathological processes.
