Published: January 2019

Предложен метод моделирования напряженно-деформированного состояния в поверхностно упрочненных элементах статически не определимых стержневых систем в условиях ползучести на примере трехэлементной несимметричной стержневой системы.
Решение задачи состоит из двух этапов: реконструкции напряженно-деформированного состояния после процедуры поверхностного пластического упрочнения цилиндрических элементов системы (пневмодробеструйная обработка микрошариками) и методики расчета релаксации остаточных напряжений в упрочненных элементах на фоне ползучести всей стержневой конструкции как целого.
В качестве определяющих реологических соотношений использовалась модель, описывающая первую и вторую стадии ползучести.
Результаты решений на обоих этапах проиллюстрированы на модельном примере ползучести систем с упрочненными элементами из сплава ЖС6У при температуре 650 °C.
Для упрочнения стержней из этого сплава использовались реальные экспериментальные данные для осевых и окружных остаточных напряжений, детально проиллюстрирована методика реконструкции напряженно-деформированного состояния после пневмодробеструйной обработки.
Для построения реологической модели использовались опытные данные для кривых одноосной ползучести сплава ЖС6У при различных постоянных напряжениях при температуре 650 °C, приведены численные значения параметров модели.
Выполнено обобщение одноосной модели на сложное напряженное состояние.
Решение основной задачи выполнено численно с использованием дискретизации по пространственной и временной координатам.
Исследовано стационарное асимптотическое напряженно-деформированное состояние стержневой системы, соответствующее стадии установившейся ползучести, которое использовалось для оценки сходимости численного метода.
Получены зависимости кинетики всех компонент тензора остаточных напряжений во всех трех упрочненных элементах системы вследствие ползучести при заданной внешней нагрузке.
Выполнен сравнительный анализ скорости релаксации остаточных напряжений в различных стержнях.
Разработано алгоритмическое и программное обеспечение для решения поставленной задачи.
Основные результаты работы иллюстрируются эпюрами распределения остаточных напряжений по глубине упрочненного слоя.
Обсуждаются вопросы применения полученных в работе результатов в прикладных задачах оценки надежности упрочненных стержневых систем.
К проблеме единственности решения задачи Коши для уравнения дробной диффузии с оператором Бесселя
Authors: Хуштова Фатима Гидовна , Khushtova Fatima Gidovna
Published: January 2019

Рассматривается уравнение дробной диффузии с сингулярным оператором Бесселя, действующим по пространственной переменной, и оператором дробного дифференцирования Римана - Лиувилля, действующим по временной переменной. Когда порядок дробной производной равен единице, а особенность у оператора Бесселя отсутствует, рассматриваемое уравнение совпадает с классическим уравнением теплопроводности. Ранее для уравнения дробной диффузии с оператором Бесселя было построено решение задачи Коши и доказана теорема единственности решения в классе функций экспоненциального роста.
Построен пример, показывающий, что увеличение показателя степени в условии, гарантирующем единственность решения задачи Коши, влечет за собой неединственность решения. С помощью известных свойств функции Райта получены оценки для построенной функции. Показывается, что она, будучи не равной тождественно нулю, удовлетворяет однородному уравнению и однородному условию Коши.

The seaweed resources of Alaska
Authors: Stekoll Michael S.
Published: January 2019

Alaska has the longest coastline of all of the states in the USA. This coastal zone stretches from the temperate zone to past the Arctic circle. Oceanographic conditions vary from quiet estuaries to exposed open coasts. Water temperatures range from over 20°C in the summer in the south to ice covered water in the north. Consequently, the marine flora is plentiful and diverse with over 500 species of seaweeds. Three species of floating kelps occur from the southern boundary to Kodiak Island and westward along the Aleutian Chain. Species of Fucus are dominant in the intertidal along most of the coastline. There is also an abundance of red algae in the intertidal and subtidal. There is only minimal subsistence and commercial utilization of the seaweed resource. The major commercial use of seaweeds is in the herring spawn-on-kelp fishery. “Black seaweed” (Pyropia sp.) is a special resource for Alaskan Native subsistence harvest. Recently, there has been increasing interest and activity in the commercial mariculture of kelps such as Saccharina latissima and Alaria marginata.
Why perceived political bias on TV does not inevitably lead to a polarized audience. The case of NRK and TV2 in Norway
Authors: Jenssen Anders Todal , Aalberg Toril
Published: January 2019

This paper investigates whether political polarization of the TV audience is emerging also in a typical democratic corporatist system. The study is motivated by the claim put forward by several US scholars, who argue that in today’s high choice information environments, partisans tend to see mainstream media as ‘hostile’ and therefore seek out and select broadcasters who confirm and deepen their worldview (Arceneaux and Johnson, 2013; Iyengar and Hahn, 2009; Tewksbury and Riles, 2015). This demand, they argue, expands the market for partisan TV and contributes to growing political polarization. We ask if there is evidence of a politically polarized Norwegian TV audience, by exploring the relationship between partisan preferences, perceived political bias and selective exposure to TV news. We find that many Norwegians believe that both the public broadcaster and the leading commercial broadcasters are politically biased. Consistent with the “hostile media hypothesis”, people on the right accuse the broadcasters of favoring the parties on the left, whereas people of the left tend to see the broadcasters as favoring the parties on the right, albeit not to the same degree. By using a survey experiment, our study also demonstrates that given the opportunity, the audience does select news stories consistent with their political beliefs from a politically ‘friendly’ broadcaster. However, they also choose news stories consistent with their political beliefs from a perceived hostile news source over politically inconsistent stories from a friendly source. This suggests that ‘friendly’ content triumphs perception of broadcaster bias. Despite widespread perceptions of partisan favoritism in the Norwegian TV market, we find few traces of a politically polarized audience. The main reason for this is that the public broadcaster still draws a wide audience across the political spectrum, as even critics consider this news source as too important and relevant to be ignored.
Hebrew and Aramaic Terms in the Extractiones de Talmud. The Term “Yeshivah” in the Thirteenth-Century Latin Translation of the Talmud
Authors: Dal Bo Federico
Published: January 2019

Translation is hardly an exceptional event. On the contrary, it is quite common and reflects the necessity of communication despite the obvious multiplicity of human languages. Therefore, it has often exhibited a practical and prescriptive nature – as a discourse characterised by instructions to translators about how, what and why to translate. In the present article, I will pay special attention to the treatment of Hebrew and Aramaic terms in the thirteenth-century Latin translation of the Talmud – better known as Extractiones de Talmud (‘Excerpts from the Talmud’). This translation is a large anthology from the Babylonian Talmud that was compiled by Christian authorities in consequence of the famous Paris process of 1240, when the Jewish convert Nicholas Donin confronted the prominent Rabbi Yehiel of Paris regarding the allegedly blasphemous, anti-Christian nature of the Talmud. This large anthology frequently emphasises linguistic difference and abounds in providing details about specific terms from Talmudic literature. Yet the Extractiones appear to neglect the complex nature of the Talmud. They never mention that the Talmud is bilingual – as it collects Hebrew and Aramaic texts – while emphasising that in it the Jews still employ the so-called ‘Holy Tongue’. I will argue that the Extractiones’ emphasis on Hebrew has both ideological and practical purposes. On the one hand, the notion that Hebrew abounds in the Talmud resonates well with the Christian expectation that Judaism is still bound to the “hebraica veritas” (‘Hebrew truth’). On the other hand, an unexperienced Christian reader might have found it difficult to come to terms with the linguistically and historically complex nature of the Talmud. Therefore, the focus on Hebrew may have been the result of an oversimplification for the readers’ sake. The case will be proven on account of one central example: the translation of the Hebrew term “yeshivah”. I will show that the treatment of this term illustrates how the Latin translator of the Talmud intended to emphasise the cultural difference between Jews and Christians, without abandoning the practical need of offering some form of cultural adaptation.
Carbon nanostructures for advanced nanocomposite mixed matrix membranes: a comprehensive overview
Authors: Salehi Ehsan , Heidary Farhad , Daraei Parisa , Keyhani Mohammad , Behjomanesh Milad
Published: January 2019

The highly progressive membrane separation technology challenges conventional separation processes such as ion exchange, distillation, precipitation, solvent extraction, and adsorption. The integration of many desired properties such as low energy consumption, high removal efficiency, affordable costs, suitable selectivity, acceptable productivity, ease of scale-up, and being environmentally friendly have made the membranes capable of being replaced with other separation technologies. Combination of membrane technology and nanoscience has revolutionized the nano-engineered materials, e.g. nanocomposites applied in advanced membrane processes. Polymer composites containing carbon nanostructures are promising choices for membrane fabrication owing to their enhanced chemistry, morphology, electromagnetic properties, and physicochemical stability. Carbon nanostructures such as carbon nanotubes (CNTs), nano graphene oxides (NGOs), and fullerenes are among the most popular nanofillers that have been successfully applied in modification of polymer membranes. Literature review shows that there is no comprehensive overview reporting the modification of mixed matrix membranes (MMMs) using carbon nanofibers, nano-activated carbons, and carbon nanospheres. The present overview focuses on the applications of carbon nanostructures mainly CNTs and NGOs in the modification of MMMs and emphasizes on the application of CNTs and NGO particles.

Pharmacological inhibition of the sonic hedgehog (SHH) pathway can be beneficial against certain cancers but detrimental in others. Adamantinomatous craniopharyngioma (ACP) is a relevant pituitary tumour, affecting children and adults, that is associated with high morbidity and increased mortality in long-term follow-up. We have previously demonstrated overactivation of the SHH pathway in both human and mouse ACP. Here, we show that this activation is ligand dependent and induced by the expression of SHH protein in a small proportion of tumour cells. We investigate the functional relevance of SHH signalling in ACP through MRI-guided preclinical studies using an ACP mouse model. Treatment with vismodegib, a clinically approved SHH pathway inhibitor, results in a significant reduction in median survival due to premature development of highly proliferative and vascularised undifferentiated tumours. Reinforcing the mouse data, SHH pathway inhibition in human ACP leads to a significant increase in tumour cell proliferation both ex vivo, in explant cultures, and in vivo, in a patient-derived xenograft model. Together, our results demonstrate a protumourigenic effect of vismodegib-mediated SHH pathway inhibition in ACP.

El trabajo de lo negativo
Authors: Muñoz Cecilia
Published: January 2019

La autora se sirve de algunas ideas de André Green sobre el “trabajo de lo negativo” para pensar la historia de odio, destrucción y muerte vividos en los últimos setenta años en Colombia. Se destacan: 1) el uso de la negación, la desmentida y la forclusión como mecanismos para excluir la verdad de la conciencia en el terreno individual y social; 2) la desaparición del yo bajo el objeto en los procesos de duelo, melancolía e identificación que se observan en el terreno social cuando el jefe poderoso impone sus ideas; 3) pulsión de muerte, desinvestidura, desobjetalización y aniquilamiento caen sobre el enemigo, pero también sobre el sí mismo de los sometidos, aquellos que han perdido su propia relación con la satisfacción, el deseo y con su estructuración psíquica (yo y superyó) bajo las demandas del líder endiosado.

EFL Teachers’ Attitudes Towards Oral Corrective Feedback: A Case Study
Authors: Gómez Argüelles Lizbeth , Hernández Méndez Edith , Perales Escudero Moisés D.
Published: January 2019

This paper reports a qualitative case study of college-level English as a foreign language teachers’ attitudes towards oral corrective feedback. Our goal is to characterize such attitudes considering a model which integrates cognitive, affective and conative components as well as different aspects of oral corrective feedback. Six English instructors working in English language teaching at a university in southern Mexico were interviewed. Directed qualitative content analysis shows that (1) participants prefer implicit corrective feedback strategies, and (2) considerations of students’ feelings guide their overall attitudes toward corrective feedback. The participants seem unaware of most corrective feedback strategies and consideration of students’ cognition is absent in the composition of their corrective feedback attitudes. This finding suggests a need for more theory-based corrective feedback training and practice.
Engaging English as a Foreign Language Students in Critical Literacy Practices: The Case of a Teacher at a Private University
Authors: Gómez Jiménez Maria Catalina , Gutierrez Claudia Patricia
Published: January 2019

This paper describes the process English as a foreign language university students and their teacher underwent when engaging in critical literacy practices. Interviews, focus groups, questionnaires, students’ artifacts, and the teacher’s journal were used to collect data in this study. Findings suggest that when students engage in critical literacy practices, they are prone to reflect on the power they have as agents of social change, while developing language skills. However, teachers should be ready to encounter some resistance from students and to struggle with the incorporation of critical perspectives in their lessons, which is understandable considering the emphasis grammar mastering has traditionally had on language teaching and learning.
Linguística Aplicada e o ensino de línguas adicionais
Authors: Lopes Rodrigo Smaha , Salles Jaqueline Laís , Pallú Nelza Mara
Published: January 2019

This article aims to highlight the importance of applied linguistics (AL) knowledge in the continuous construction of pedagogical practices involving language teaching and learning and, through the relationship between teaching methods and approaches, and the research development in AL, to show how the teacher’s role has changed, from the beginning of LA to what has been called today the Post-method – Prabhu (1990), Kumaravadivelu (1994, 2001) and Celani (2009). In this scenario, it is the teacher who determines – or should determine – which method/approach will be most profitable, based on the investigation of its context and not a priori. It is hoped that this work will contribute to the additional language teacher’s reflection on their classroom practices – why, what for, how and what to teach –, to transform them, to educate themselves critically-reflexively and to become, in fact, a teacher-researcher.
Designing classroom material to promote socialization and social change
Authors: Cardoso Vinícius Borges de Medeiros
Published: January 2019

This paper will review the process of developing two units of a coursebook that aimed to promote socialization and social change. Teaching perspectives on the Communicative Approach and Critical Literacy are reviewed, advocating the possibility of linking both perspectives. The methods of dealing with the receptive and productive skills and three language systems – grammar, vocabulary, and pronunciation – are synthesized and reasons for supporting the choice of the activities in the units are given throughout the article. The results of this study suggest that the coursebook syllabus can bring together both the possibility of socialization, fostered by the Communicative Approach, and social change, encouraged by the Critical Literacy. Thus, coursebooks are important factors to promote students’ active citizenship.

Playing By Their Rules
Authors: Blume Carolyn
Published: January 2019

While digital gameplaying is increasingly recognized for its potential for language learning, its use among English as a foreign language (EFL) teachers in both leisure and pedagogical contexts is comparatively meagre. Assumptions regarding the appropriate nature of schooling on the one hand and appropriate leisure pursuits on the other mediate beliefs about digital gaming to generate skepticism of gameplaying among many educators. Their devaluation of digital game-based language learning (DGBLL) has implications for language learning, not just in terms of skills and attitudes, but in regard to the development of linguistic capital. The purpose of this article is to use the concept of habitus to examine the reasons why educators marginalize DGBLL and the implications of such pedagogic decisions on the development of linguistic capital. Given the emergent empirical base, this contribution adopts a theoretical approach to contextualize observed trends. The article concludes by discussing the importance of teacher-mediated DGBLL for reasons of access and equity before recommending ways of integrating DGBLL to achieve these goals.

Authors: Kul'metyeva V. B. , Porozova S. E. , Gilev V. G. , Vokhmyanin D. S.
Published: January 2019

The eﬀect of annealing and sintering temperatures on the phase transformations of ZrO2was studied depending on the content of REE concentrate using diﬀerential thermal analysis, Raman spectroscopy andX-ray diﬀraction. It is shown that the introduction of REE concentrate in an amount of more than 15 wt. % stabilizes the tetragonal phase of ZrO2only at temperatures below 1200 °C. A further increase in temperature leads to destabilization of the tetragonal phase with the formation of the monoclinic and cubic phases of theLn2Zr2O7type isostructural compounds (n= La, Nd, ...) with the pyrochlore structure.Ill. 8.

Published: January 2019

The synthesis of the Ti2AlN-based material by means of the mechanical activation (MA) of the Ti‒AlN powder mixture in the planetary mill followed by the vacuum spark-plasma sintering (SPS). It was shown that the phase ratio AlN/Ti gradually decreases under mechanical activation. The data are given on the sample's phase composition, density and hardness after the SPS. The maximum Ti2AlN content value of 90 mass percent was achieved at the SPS temperature 1300 °C. The samples had the lowest porosity value of 1,9 % at the SPS temperature 1200‒1300 °C, the HV0,5hardness being close to 7 GPa.

Seçilmiş İslam Ülkeleri İçin Satın Alma Gücü Paritesinin Geçerliliği Üzerine Bir Çalışma
Authors: HATİPOĞLU Mercan
Published: January 2019

Bu çalışmanın amacı seçilmiş İslam ülkeleri için satın
alma gücü paritesinin (SGP) geçerliliğini tespit etmektir. Satın alma gücü
paritesi döviz kurlarının fiyatlar genel seviyesi tarafından belirlendiğini
savunmaktadır. Eğer parite geçerli ise döviz kurunun dengeye gelmesi için
herhangi bir müdahale gerekmeyecektir. Ancak döviz kurları, birçok
öngörülemeyen durumla, finansal krizler ve hükümet müdahalelerine maruz
kaldıkları için, klasik birim kök testleri böyle olayları yeterince
modellemekte başarısız olmaktadır. Bu yüzden ekonomi politikalarından sorumlu
kurum ya da kişiler SGP’nin geçerli olup olmadığına karar verirken tereddüt
yaşamaktadır. Markov rejim değiştirme modelinin, döviz kurlarını yükselirken ve
düşerken aynı anda analiz edebildiği için literatürde klasik testlere göre daha
iyi sonuçlar verdiği kanıtlanmıştır. Bu çalışmada Markov rejim değiştirme
testleri kullanılarak Malezya ve Endonezya için SGP’nin geçerli olduğu
bulunmuştur. Öte yandan bulgular Fas ve Birleşik Arap Emirlikleri’nde SGP’nin
lehine kanıtlar sağlayamamıştır.

Published: January 2019

Vergilerin etkin bir şekilde
tahsil edilebilmesinde mükelleflerin vergiye karşı olan tutum ve davranışları
oldukça önemlidir. Mükellefin vergiye yönelik tutum ve davranışlarını ise vergi
algıları belirlemektedir. Vergi algısının etkileyen faktörler içerisinde en
önemlilerinin vergi adalet ve vergi affı olduğunu söylemek mümkündür. Bu
çalışmada vergi denetim algısına sahip mükelleflerin vergi adaleti ve vergi
affı uygulamalarına bakışını araştırmak amacıyla Uşak ilinde faaliyet gösteren
gelir vergisi mükellefleri üzerine ampirik bir çalışma gerçekleştirilmiştir.
Elde edilen verilerin yorumlanmasında SPSS 23.0 paket programı kapsamında
çapraz tablolar analiz yönteminden yararlanılmıştır. Çalışma sonucunda vergi
denetim algısına sahip mükelleflerin vergi adaleti ve vergi aflarına bakışları
konusunda bir takım veriler elde edilmiş olup vergi sisteminde adaletin
sağlanmasında vergi denetimlerinin yerinin ne denli önemli olduğuna ilişkin
bulgulara erişilmiştir. Ayrıca vergi denetimlerinin etkinliğinin önünde vergi
aflarının bir engel teşkil ettiği sonucuna da ulaşılmış ve tüm bu hususlarla
ilgili bir takım önerilerde bulunulmuştur.
Exploring Linking Social Capital in Economic Development
Authors: İZMEN Ümit
Published: January 2019

Linking social capital is a
concept suitable for the study of the nature, extent and economic impact of
social interactions with politicians or officials. By reviewing the development
of the concept and its application in economic development, this paper aims to
gain insight into the usefulness of the concept of linking social capital in
economic development studies where political system is internalized. The
appropriateness of the concept is reviewed through an in-depth analysis of main
theoretical contributions and papers selected from Thomson Reuters’ Web of
Science Core Collection.  Studies that
conceptualize linking social capital as shaped by political institutions are
rare. Lack of consensus on the definition and measurement of linking social
capital limited its usefulness. The paper concludes with a call for clarity in
the definition of the concept à la Bourdieu and for further studies that
explore the economic impact of social capital under different political
environments.
Ticari Dışa Açıklığın Bölgesel İşsizlik Üzerindeki Etkisi: Türkiye Örneği
Authors: ERCAN Onur , KILIÇ Esin
Published: January 2019

Bölgesel işsizlik oranları,
bölgesel gelişmişliğin emek piyasasına ilişkin temel göstergesi olarak ele
alınmaktadır. Dolayısıyla, işsizlikle mücadele politikaları yatırımların
bölgelere yayılmasını da sağlamalıdır. Ayrıca, dış ticaret daha geniş piyasalar
için üretimi beraberinde getireceğinden; istihdam düzeyi, işletmelerin dış
ticarete yönlendirilmesiyle de arttırılabilir. Bu nedenle, bölgesel düzeyde
ticari dışa açıklık ile işsizlik arasındaki ilişkinin araştırılması önemlidir. Bu
çalışmada Türkiye’de bölgesel ticari dışa açıklık ile işsizlik arasındaki ilişki,
2004-2014 dönemi için dinamik doğrusal panel veri analizi yöntemleri
kullanılarak araştırılmıştır. Analiz sonuçları bölgesel ticari dışa açıklık
endeksleri ile işsizlik oranı arasında negatif bir ilişki olduğunu işaret
etmiştir. Ayrıca, Dumitrescu-Hurlin panel nedensellik testi sonuçları, bu iki
değişken arasındaki ilişkinin çift yönlü olduğunu göstermiştir. Elde edilen
sonuçlar, Türkiye’de bölgesel ticari dışa açıklığın arttırılmasına yönelik
uygulanacak politikaların bölgesel işsizlik oranlarını azaltabileceği şeklinde
yorumlanabilir.

Authors: Higueras Georgina
Published: January 2019

The pendulum of History leaves the West to return to the East, as in the times of Marco Polo. China has found in the resurrection of the Silk Road the instrument for a more inclusive global economic growth and that is also in line with the multipolar world that the government proposes. In just five years, The Belt and Road Initiative, as it is formally referred to, has made great strides in its revolutionary global connection plan and added new followers, despite of the swiftness of the Chinese’s ascent is scaring many countries, especially its neighbors. The purpose of this article is to analyze the misgivings of Europe and the range of opportunities that Beijing isoffering to create together a model of sustainabledevelopment and address the major challengesthat affect both: inequality, climate change andprotectionist drift. The New Silk Road is a uniqueopportunity to bring closer the two extremes ofEurasia, which today, more than ever, need tounderstand each other.
Human Capital, Training Pathways and Educational and Professional Guidance in China
Authors: Doncel Abad David
Published: January 2019

One of the Government's priorities is to swap from an industrial economy and low salaries to one of Services and high salaries. For this, the government needs to increase the quality of Human Capital, understood as the increase in the average educational level of the population. An educational measure to achieve this goal is to enhance educational and vocational guidance. Orientation is conceived as a measure designed to optimize the adjustment between the education system and labor market. Although it is a measure present in the Chinese educational system before, it is not until 2012, when the government is committed to a model of Educational andProfessional Guidance focused on the developmentof the individual's career. The objective of thispaper is to analyze how educational transitionsare from one educational stage to another, andfrom one educational level to another, to knowthe problems and factors associated with droppedfrom school. Once detected the different typesof transition in the Chinese education system.We contrast it with the theoretical model ofeducational and professional guidance focusedon the development of the individual's vocationalcareer. At the methodological level, a review ofthe research and of the databases to be usedis carried out. Finally, the results show howdifferent itinerary models that Chinese studentstake according to their socio-educational profiledo not fit with the theoretical model of CareerEducation.
