Frequency Domain Backoff for Continuous Beamforming Space Division Multiple Access on Massive MIMO Wireless Backhaul Systems
Authors: Maruta Kazuki
Published: January 2020

This paper newly proposes a frequency domain backoff scheme dedicated to continuous beamforming space division multiple access (CB-SDMA) on massive antenna systems for wireless entrance (MAS-WE). The entrance base station (EBS) has individual base band signal processing units for respective relay stations (RSs) to be accommodated. EBS then continuously applies beamforming weight to transmission/reception signals. CB-SDMA yields virtual point-to-point backhaul link where radio resource control messages and complicated multiuser scheduling are not required. This simplified structure allows RSs to work in a distributed manner. However, one issue remains to be resolved; overloaded multiple access resulting in collision due to its random access nature. The frequency domain backoff mechanism is introduced instead of the time domain one. It can flexibly avoid co-channel interference caused by excessive spatial multiplexing. Computer simulation verifies its superiority in terms of system throughput and packet delay.

Authors: Morera-fernandez Mercedes , Morera-mesa Aram , Morera-fumero Miguel Angel , Hernandez-perez Javier , Morera-fumero Armando Luis
Published: January 2020

Peer interactions and teacher student interactions are essential components of learning upon which
cooperative learning (CL) is rooted. Empirical data about this type of interactions are scanty. The aim
of this research is to compare students’ opinions about the student-student and student-teacher
interactions in a CL method (Jigsaw II/puzzle) and the conventional teacher learning method after
learning an economics teaching unit in a secondary education school. The study was carried out in a
secondary education level institute in the island of Tenerife, Canary Islands (Spain) during the 20172018

academic year. Twenty-eight students took part in the study. Students were taught a unit
through the conventional teacher exposition method and later through a CL technique (Jigsaw
II/puzzle). Peer interactions and teacher-student interaction were evaluated through a 5-point Likertscale.

Students were evaluated twice, during the conventional instruction and approximately two
weeks later after receiving the CL instruction. The total score of interactions among peers was
significantly higher with the CL method than the conventional method (conventional method: 19.92
± 2.26 vs CL method: 21.54 ± 2.75, p < 0.009). There were no significant differences between the
methods of learning in the total score of the interaction with the teacher (conventional method:
17.17±1.61 vs CL method: 16.37±2.78, p < 0.098), but in item 9 (interchange of information with the
teacher) the score in conventional method was significantly higher than in the CL technique (4.50 ±
0.59 vs 4.21 ± 0.72, p < 0.016). In conclusion, the secondary education students consider that
puzzle/jigsaw II CL technique promotes relationships among peers more than conventional learning
while there is no difference between the puzzle/jigsaw II CL technique and the conventional learning
in the teacher-student relationships.

Published: January 2020

Introduction

Oxidative stress (OS) seems to be an important mediator of cellular injury, from which sepsis can proceed. Studies have demonstrated the protective effect of controlled hypothermia in sepsis. This study aimed to evaluate its effects on OS parameters in rat hepatic and renal tissue septic after caecal ligation and puncture (CLP).

Material and Methods

Three groups were appointed (10 rats/group): C (control), SN (sepsis normothermic), and SH (sepsis hypothermic). Ten hours from CLP, the liver and kidneys were harvested and total protein concentration, superoxide dismutase (SOD), glutathione peroxidase (GPx) activities, lipid peroxidation level (malondialdehyde (MDA), carbonylated proteins (2,4-dinitrophenylhydrazine (DNPH), and fatty acid profile were analysed.

Results

Sepsis significantly increased SOD and GPx activities in the liver, regardless of the temperature. In renal tissue, GPx activity increased significantly in normothermic conditions and SOD tended to decrease in hypothermic conditions. MDA and DNPH concentrations increase in both tissues after CLP. Hypothermia significantly lowered MDA in the liver but only changed it insignificantly in the kidneys. The DNPH in the liver and kidneys was significantly lower in hypothermic conditions. The unsaturated-to-saturated fatty acids ratio was significantly lower in sepsis, and the fall in temperature raised this ratio.

Conclusion

Experimentally induced sepsis in rats enhances OS in the liver and kidneys. The effect of hypothermia on OS indices is dependent on the type of tissue.
A SNAPSHOT METHODOLOGICAL REVIEW OF JOURNAL ARTICLES IN ENGINEERING EDUCATION RESEARCH
Authors: Liu Qin
Published: January 2020

Explicit discussion of methodology is important to better understand how knowledge claims are made in a field. In light of a methodological taxonomy, this exploratory review paper examined the research topics and methodologies that were used in a sample of 142 articles published in 2018 by four major engineering education journals. The analysis reveals that engineering education research exhibits varied profiles in different engineering education journals. It also identifies several patterns and trends in the current state of engineering education research. The findings will not only provide novice engineering education researchers with a snapshot, yet an illustrating view, of the emerging field of EER but also offer a starting point to examine critical questions in the field of EER, such as quality and rigor.
EXPLORING STUDENTS’ DEFINITIONS OF SUCCESS: A REVIEW OF THE LITERATURE
Authors: Ullrich Max , Strong David S.
Published: January 2020

The term “success” has many different meanings for students and stakeholders in the academic environment [1]. The most common measure of student success employed by researchers and institutions is performance-based measures such as grades and graduation rates. The remainder of the definitions are inconsistent among the various stakeholders in the academic environment. Understanding the importance of the criteria used by students to define their success in Canadian undergraduate engineering programs, as well as the degree to which students are motivated to engage in each criterion with a mastery-based approach, could be useful for reconciling the differences between the student group and the other stakeholders in the academic environment and assist in designing teaching strategies that align with these criteria and thus promote a masterybased view of success.

This paper summarizes three achievement motivation frameworks and contributes a synthesis of the literature regarding student and other stakeholder definitions of student success to identify opportunities and methodologies in preparation for a research study on this topic as it applies to success in the context of Canadian undergraduate engineering students.
EXAM-WRAPPERS AS A TOOL TO ENHANCE STUDENTS’ METACOGNITIVE SKILLS IN MACHINE ELEMENT DESIGN CLASS
Authors: El Bojairami Ibrahim , Driscoll Mark
Published: January 2020

Acquiring metacognitive skills, i.e. selfassessment of study behaviors through exam-wrappers, would potentially have concrete positive effects on students learning. The purpose of this study was to assess the link between students’ performance and study behaviors, to analyze their metacognitive skills.  Exam-wrappers consisted of 4 fundamental questions and were utilized in an undergraduate engineering class, Machine Element Design, at McGill University. Data were later collected and analyzed using statistical analyses. Results showed an overall increasing trend between the quality of reflection and students grades’ improvement, with the highest being a 47.5 increase in grade for a student who scored a 10/10 reflection.  Analyzed cases led to the conclusion that students were able to use their metacognitive skills to self-assess, and accordingly adjust their study behaviors and goals, to thrive at a better performance.
FIVE CAPABILITIES OF DESIGN ENGINEERS: TOWARDS UNDERSTANDING THE TRANSDISCIPLINARY COMPETENCIES
Authors: Ha Minha R. , Czekanski Aleksander
Published: January 2020

Today there is a growing emphasis on responsible engineering design, which commits its practice to sustainable, ethical, equitable outcomes in the broader societal level. For engineers involved in the design, development, and implementation of existing and emerging technologies, such responsibility requires skillfulness on multiple fronts, for example: facilitating the integration of cross-disciplinary expertise and knowledge; translating a detailed problem understanding from its sociocultural settings into technical requirements; and negotiating requirements and priorities with key internal and external stakeholders. In order to understand how design engineers access, acquire, and effectively utilize knowledge outside their technical disciplines, especially pertaining to the human and social contexts of the design problem and designer practice, an online survey and in-depth interviews were conducted with professional engineers. The paper discusses potentially important design engineer capabilities that engineering educators should consider. We welcome discussions and feedback on our ongoing work.

Hal ini berarti aktivitas pengangkatan CPU tidak berbahaya karena F comp kurang dari 6500 N.
Revocation Of Re-Elected Rights For Corruptor In Public Offices Without Time Limitation The Progressive Law Perspective
Authors: Mubayyinah Fira
Published: January 2020

The problem of corruption has always been a public discussion, not only because of its consequences. But also because the perpetrators of corruption that they caught were from political parties. And it tends to be after they go through the criminal period, re-enter the area of policy holders or authority through political channels again. Additional criminal imposition of revocation of political rights for the corutor is stated in the Decision of the Supreme Court Number: 537k / Pid.Sus / 2014, and Number 1195K / Pid.Sus / 2014. The application is not limited to the period as stipulated in article 38 of the Criminal Code. Revocation of political rights on the one hand is considered contrary to human rights, but revocation of political rights becomes an important punishment imposed, considering that the perpetrators of corruption do not come from political parties. The application of criminal acts is a means of reason to prevent criminal acts. Revocation of political rights which is still debated can have an impact on its implementation. Therefore, in its implementation, of course requires a Law Enforcement Officer who has a step of thinking and progressive steps. Penal punishment is the authority of the Judge. Judges in imposing crimes should rely on the principle of substantive justice and are intended to provide protection to society (social deffence)
Review Of Islamic Law To The Use Of Article 28 Subsection 2 About Speech Hatred And Defamation (UU Number 19 AT 2016 Amendments to UU Number 11 at 2018)
Authors: Rasyid Arbanur
Published: January 2020

Hate Speech  has recently become a warm conversation, not only in the media, but has begun to be discussed in scientific forums as a result of the many characters who are ensnared by hate speech due to making uploads in Social Media that is considered insulting to other people or state institutions by making a statement containing elements of hate speech in accordance with the criminal threat in Article 28 paragraph 2 of Law number 19 of 2016 amendment to law number 11 of 2008. Long before the law talks about hate speech, Islam through the Qur'an speaks a lot about how God denounces the actions of people who insult, berate, speak ill of others and make hoaxes, and Allah threatens sin for those who do it . Even in the history of Islam through the Prophet Muhammad had given a caning to people who make hoaxes, and the sentence in the Islamic criminal law is called Ta'zir, thus Islam is very careful and highly respects the human rights of a person including in protecting the soul and someone's honor
Melissus and the Оne
Authors: Ignatenko E. A.
Published: January 2020

It is established that Melissus associated with the concept of “the one” all-encompassing “all-one”, uniting in itself, as in “whole”, an infinite number of particles, which in their likeness should be, as “one single whole”. And this similarity means similarity in homogeneous existence. Homogeneity – embracing the entirety of “single” and ”multiple”, “single” and “parts”. Additionally it is established that Melissus considered existing material principles and material elements, which remain unchanged, like “whole” at levels beyond human sensory perception (sight, hearing, etc.). It was revealed that Melissus denied the possibility of knowing the true essence of things and bodies with the help of these senses. The world from the perspective of the infinite, eternal “one” is knowable, according to Melissus, only by reason.
On the Authenticity of Protagoras’ Myth and its Role in Plato’s Protagoras
Authors: Bazhenova E. A.
Published: January 2020

The article discusses the thesis according to which Protagoras’ myth in the dialogue of the same name by Plato originates in its core from the historical Protagoras. Although the author aligns with this thesis’ supporters, the analysis of the myth in the context of the dialogue as a whole, including dramatic features of the latter, allows her to presume that the myth is intended not so much to convey the views of the famous sophist as to contribute to the creation of the satirical image of his through which Plato ridicules Protagoras’ philosophical and pedagogical ambitions.
Epistemic Disagreement in Social Epistemology
Authors: Maslov D. K.
Published: January 2020

The article presents the problem of epistemic disagreement as part of social epistemology, particularly considering the conditions of rational disagreement (equal weight view). Against this background some versions of epistemic “bootstrapping” are addressed that serve to give advantage to one of the disputing parties. As a result, a conclusion is drawn that the kinds of bootstrapping portrayed are epistemically irrelevant, which also casts doubt on Bayesian epistemology, for it mixes two different types of rational decision making – practical and epistemic.
Revolutionary Waves of the Twentieth Century: “The Red Wave” in Asia, 1940–1970
Authors: Tsygankov V. V.
Published: January 2020

The study examines revolutionary waves – the process of spreading protest activity from one society to another. The author reveals the specifics and analyzes the nature of relations within the “red wave” in post-war Asia in the 40s – 70s of the twentieth century. The paper explains the structural, ideological and organizational relationship between these revolutions (uprising, partisan wars) using the world system analysis, demographic and structural theory, the theory of military revolutions, and the neo-Marxist model of B. Moore. These approaches helped to explain the authoritarian, dirigiste an egalitarian Asian “wave”, and also highlighted two ideologically and organizationally separate “waves”.

Authors: Shekhar Bhawani , Kumar Sunesh , Mathur Sandeep , Singhal Seema , Meena Jyoti , Sharma D. N. , Singh Neeta
Published: January 2020

Context:

Endometrial cancer is a frequently encountered gynecological malignancy. An adverse prognostic immunohistochemical marker had not been identified until recently. Recent studies have used human epidermal growth factor receptor 2 (HER2)/neu expression as a marker for adverse outcomes in carcinoma endometrium, as proven in carcinoma breast.

Aim:

The present study was undertaken to correlate HER2/neu expression with prognostic factors in cases of endometrial carcinoma.

Materials and Methods:

This was a prospective study on evaluation of HER2/neu expression done on 30 patients with biopsy-proven carcinoma endometrium admitted in the hospital for staging laparotomy. Histopathological examination was performed and HER2/neu expression was assessed by immunohistochemistry and was categorized into (1) Group 1: HER2/neu 0/1+ (negative), (2) Group 2: HER2/neu 2+ (equivocal), and (3) Group 3: HER2/neu 3+ (positive). All the cases were followed up for a period of 1 year.

Statistical Analysis:

All data analyses were carried out using statistical software SPSS, IBM version 21.0. P< 0.05 was considered as significant.

Results:

0/1+ HER2/neu expression (negative) was detected in 19 patients (63.33%), 2+ HER2/neu expression (equivocal) was detected in 4 patients (13.33%), and 3+ HER2/neu expression (positive) was detected in 7 patients (23.33%). HER2/neu 3+ group was significantly associated with non-endometrioid histology (P = 0.003) and high tumor grade (P = 0.005). The association of HER2/neu 3+ group with advanced disease and lymph node involvement showed a trend, but it was not statistically significant. No association was found between HER2/neu overexpression and extent of myometrial invasion. There were two recurrences in 1 year follow-up period. HER2/ neu expression (2+ and 3+) was seen the recurrence cases.

Conclusion:

HER2/neu overexpression was found to be an adverse prognostic marker in carcinoma endometrium, which could form the basis of targeted chemotherapy.
Bypassing the Inertness of Aziridine/CO2 Systems to Access 5-Aryl-2 Oxazolidinones: Catalyst-Free Synthesis in Water Under Ambient Conditions
Authors: Bresciani Giulio , Antico Emanuele , Ciancaleoni Gianluca , Zacchini Stefano , Pampaloni Guido , Marchetti Fabio
Published: January 2020

The development of sustainable synthetic routes to access valuable oxazolidinones via CO2 fixation is currently a hot topic of research, and the aziridine/carbon dioxide coupling has aroused a particular interest. This reaction is featured by a high activation barrier, thus it requires a catalytic system and often presents some other critical issues. Here, we describe the first gram-scale synthesis of a large number of 5-aryl-2-oxazolidinones at ambient temperature and atmospheric CO2 pressure, in the absence of any catalyst/co-catalyst and using water as solvent. The key to this innovative procedure consists in the direct transfer of the CO2/amine adduct (carbamate) to common aziridine precursors (dimethylsulfonium salts), replacing the classical sequential addition of amine (intermediate isolation of aziridine) and then CO2. The reaction mechanism has been elucidated by NMR studies and DFT calculations applied to model cases.

Published: January 2020

The first case of bacterial infection was recorded in 1862, while it was first isolated in 1882 from the scientist Gessard, who was called Bacillus pyocyaneus. The most common infections caused by bacteria are the first bacteremia in patients with serious burns, chronic lung injuries in patients with cystic fibrosis, and acute ulcerative keratitis in people who use contact lenses. The gastrointestinal tract is an important gateway for entry into the blood infection caused by bacteria, and the bacteria cause endocarditis, where the bacteria infects the heart valves from the direct invasion of the bloodstream, as it causes meningitis and brain abscesses, and it can invade the central organ The inner and nasal sinuses can also be accessed from a site far from the injury, such as the urinary tract. Other pathogenic infections caused by bacteria are pulmonary injuries, as bacteria are the most common disease associated with lung injuries. They are caused by bacteria Hospitalized lung with a mortality rate greater than 70%. Bacteria are a common cause and acquired by hospitals for urinary tract infections due to their ability to adhere to urinary epithelial cells in the bladder, as they cause cystitis and urinary tract infections. The percentage of deaths caused by bacteria can reach 50% due to many factors, including weak body defenses and bacteria resistance to anti-life as well as the production of bacteria, enzymes and external toxins.

Solvent used in extraction process of agarwood: a systematic review
Authors: Zakaria F. , Talip B.A. , Kahar E.E.M. , Muhammad N. , Abdullah N. , Basri H.
Published: January 2020

The method of extraction of Agarwood is usually dependent on the purpose of the extract.
This systematic review aims to look at the number of studies that use different types of
solvents in the process of extraction. There are 3 types of solvents commonly used in the
extraction of agarwood essential oils namely methanol, ethanol and water. Each solvent
produces different extracts in terms of quantity and quality of the final product. However,
there is controversy over the use of solvents as it may cause a cytotoxic effect on the user.
Another common type of solvent is water. Although water is a cheap solvent and
relatively safe, aqueous extracts have more impurities that make isolating the desired
compound difficult. After the extraction process, the crude extract was fractionated into
the desired compounds and this technique is widely applied, especially in the whole
process of extraction of the agarwood. In conclusion, extraction solvents have certain
advantages and disadvantages, and this is one of the reasons why this extraction method
depends on the purpose of using the final product such as agarwood essential oil.

Reciprocal Teaching merupakan model pembelajaran yang mengutamakan peran aktif siswa dalam pembelajaran untuk membangun pemahamannya dan mengembangkan kemampuan komunikasi secara mandiri. Prinsip tersebut sejalan dengan prinsip dasar konstruktivisme yang beranggapan bahwa pengetahuan itu merupakan konstruksi (bentukan) dari sesuatu yang diketahui untuk  mengetahui sesuatu. Pengetahuan itu bukanlah suatu fakta yang tinggal ditemukan, melainkan suatu perumusan yang diciptakan orang yang sedang mempelajarinya.Dengan demikian, proses pembelajaran merupakan suatu proses aktif siswa yang sedang belajar untuk membangun pengetahuannya sendiri, sedangkan guru berperan menyediakan suasana/kondisi belajar yang mendukung proses konstruksi pengetahuan pada diri peserta didik. Melalui Reciprocal Teaching peserta didik diajarkan empat strategi pamahaman pengaturan diri spesifik yaitu perangkuman(summarizing), pengajuan pertanyaan(questioning), menjelaskan (clarifing)prediksi(prediction). Kata Kunci: Reciprocal Teaching, Pendekatan Saintifik, Pembelajaran Bahasa Berbasis Teks

Published: January 2020

The wild boar population has been on a permanent increase over the last decades, causing conflicts with the requirements of modern human society. Existing effort to stabilize wild boar numbers generally fails with one of the causes being the high reproductive potential of wild boar. The aim of this study was to assess the onset of sexual maturity in wild boar males with regard to age, physical frame and environmental conditions on the basis of testicle development and sperm production. This study assessed the dimensions of gonads and the occurrence of sperm in boars caught during common hunts. Environmental conditions were found as an important factor for growth and sexual maturity of wild boar males. The body weight was a more important factor for sperm production than the age of young wild boar males. The weight threshold for sperm production in the testes was 29 kg of live weight, which corresponds to 6 months of age on average. This study has proven that environmental conditions are a significant factor affecting the physical development of male wild boars, more specifically the growth rate of their body frames and the onset of sexual maturity. In a better quality environment boars grow faster and enter puberty at an earlier age. Poor food supply and/or high hunting pressure result in slower body and testicular growth, as well as the production of sperm at a later age (approx. 2-3 months later).

Authors: Straffon-Olivares Diana Karina , Valencia-Ortiz Andromeda Ivette , Bautista-Díaz Maria Leticia , Lima-Quezada Alejandra
Published: January 2020

Los hábitos alimentarios saludables son un factor protector de la salud, mientras que los inadecuados aumentan los diferentes problemas de salud en adultos y particularmente, en niños. Los malos hábitos alimentarios y la presencia de trastornos psicológicos, como síntomas de depresión, aumentan los riesgos para la salud. El objetivo de este estudio fue determinar la asociación entre los hábitos alimentarios y los síntomas de depresión en niños escolares mexicanos, en un seguimiento a un año. Con un diseño longitudinal de panel no-experimental, participó una muestra no probabilística-intencional de 64 niños (rango de edad de 8 a 10 años). Las mediciones se identificaron como evaluación 2016 y 2017. Los participantes contestaron en una sesión el Inventario de Depresión Infantil (CDI) y el Cuestionario de Sobreingesta (OQ), esto posterior al consentimiento informado de sus padres. Se encontró una mayor cantidad de correlaciones significativas en la evaluación 2017 comparada con la del 2016 (rs; p <.05) tanto en niños como en niñas. Específicamente, con la muestra total, evaluación 2016, se destaca la asociación más fuerte entre la imagen corporal y el CDI total (rs = -.46; p <.05), mientras que en la evaluación 2017, destaca la asociación más fuerte entre la alteración afectiva y el CDI total (rs = .62; p <.05). Se concluye que en niños y niñas, la percepción de la imagen corporal empeora con los síntomas de depresión, pero con el paso del tiempo, una mayor alteración afectiva empeora los hábitos de salud

Birinci Haçlı Seferi sırasında İmparator I. Aleksios Komnenos ile Haçlı liderleri öncesinde Bizans’ın egemenliğinde olan yerlerin ele geçirilmesi durumunda iade edilmesi üzerinde anlaşmaya varmışlardır. Ancak bu kapsamda Bizans’a teslim
edilmesi gereken Antakya’da I. Bohemund (ö.1111) bir Haçlı teşekkülü kurunca ilişkiler düşmanca bir hal almıştır. Bizans’ın Aleksios Komnenos ile yeniden başlayan kudretlenme devri Ioannes Komnenos zamanında iyice kendini göstermeye
başlamıştır. Bu dönemde Balkanlardaki sorunlar çözülmüş ve Selçuklulara karşı yapılan mücadeleler artmıştır. Öte yandan 1137-1138 yılında Ioannes Komnenos, babası zamanında yapılan anlaşma gereği Antakya’yı Bizans İmparatorluğu’na
katmak için sefer düzenlemiştir. Bu sefer sırasında Kilikya’ya hakim olmuş burada hüküm süren Baron I .Leon’u esir alarak İstanbul’a götürmüştür. Ancak seferin Suriye’ye uzattığında Haçlıların hilekarlıkları nedeniyle bir başarı
elde edememiştir. 1143 yılında ikinci kez sefer düzenlemeye hazırlandığı sıralarda vefat etmiştir. Bundan sonra imparator olan Manuel 1159 yılındaki seferiyle Kilikya Ermeni Baronluğu, Antakya Prinkepsliği ve Kudüs Haçlı Krallığı’nı
kendine bağlamayı başarmıştır. Onun bu çabası bölgede Bizans otoritesini arttırdığı gibi Halep Atabeyi olan Nureddin Mahmud’un(ö.1174) Antakya’ya kesin bir saldırı düzenlemesini de engellemiştir. Bu sayede Antakya Prinkepsliği’nin
siyasi hayatı uzamıştır.
SOME DATA ON ISTANBUL'S FIRST METEOROLOGICAL RECORDS AND AN EVALUATION
Authors: OĞUZ Ahmet
Published: January 2020

Osmanlı Devletinin ilk özel gazetesi olan Ceride-i Havadis Gazetesinde iç de dış haberler olmak üzere pek çok yazı kaleme alınmıştır. İstanbul ile ilgili olarak da pek çok yazı, haber ve benzeri veriler yer almıştır. İstanbul konulu
çıkan haberler arasında meteorolojik haberler de yer almıştır. 1841 tarihinden itibaren İstanbul'un sıcaklık değerleri verilmeye başlamıştır. Bu sıcaklık ölçümleri İstanbul 'a gelen batılı meraklı gözlemciler tarafından (Mr. Henri
Lyne gibi) amatörce ölçümler yapılarak kaydedilmiştir. Gazetenin bu verileri nasıl elde ettiği meçhuldür. 1841 tarihinde yapılan sıcaklık ölçümlerini kimin yaptığı bilinmemektedir. Bu bilgiler haricinde konuyla ilgili daha başka
haberlere rastlanmamıştır. Türkiye’de Meteoroloji çalışmaları 1867’den itibaren resmen başlamıştır. 1925 tarihinden sonra da Ankara- Etlikte Meteoroloji Müdürlüğü kurulmuştur.
The World View of B. V. Shergin (On Basis of the Material of Comparisons)
Authors: Morozova O. E.
Published: January 2020

The article deals with B. Shergin’s world view represented in figurative comparisons. The artistic prose and diaries of the writer were used as a source of linguistic material. The research material was obtained as a result of purposive sampling. The aim is to characterize the features of the conceptual system and the world view of B. Shergin, shaped by Russian Northern culture, art education and religious views of the writer. The semantic spheres, which had an importance for the writer (nature, human, artifacts, sphere of «Me») and manifested in comparisons were considered. The key concepts having a particular significance for the writer («ship», «house», «sea», «river», «nature», «soul») were identified. Correlations between these concepts intertwined into a single conceptual system, which consists of universal, regional and the writer’s unique components, were established.
The Features of B. Shergin’s Cognitive Style (On the Example of the Conceptualization of the Image of the Sea)
Authors: Sidorova T. A.
Published: January 2020

The main aim of this research was to identify the features of B. V. Shergin’s cognitive style through comprehension of the artistic image of the sea in the works of this writer. An analysis of this image was conducted from the standpoint of cognitive poetic. Cognitive poetic is considered as the main method of linguopoetic interpretation of a literary text, whose basic principles include analysis of conceptual structures reflected in the text. In the process of research, the concept of “cognitive style” in correlation with the literary text was clarified, The components of cognitive style, objectified by the image of the sea were specified. Since the literary text was interpreted from the position of cognitive poetics, the main attention was paid not only to linguistic, but also to mental structures. Furthermore, the article explores the wellknown structures of knowledge: presuppositions, concepts, motives, ideas, etc., along with semantic dominants and semantic constructs as strong meaning formations, which are determined by the author’s needs, values, world view and world perception. Therefore, the process of text interpretation takes into account the specificity of linguistic and artistic consciousness of the author, including features of the socio-cultural consciousness of Pomors (members of a subculture). The study showed that each component of B. V. Shergin’s cognitive style has its specific characteristics. The manner of presenting information in the text is characterized by a special emotional tension: understandable and close to the people daily life gets an ontological understanding. Among the cognitive mechanisms, the secondary conceptualization of the concepts of Russian Northern culture plays a special role: many of them acquire a sign of spirituality. It is shown that the specifics of the author’s cognitive style is determined by the features of his consciousness; therefore, the knowledge as sententias, semantic dominants, semantic constructs, stereotypes, values and oppositions holds the central position.

Published: January 2020

Despite the pivotal role of risk management very limited research is carry out on the issue of firm’s risk management capability and value creation. This study aims to analyze the impact of firms risk management capabilities on firm performance and cost. Using panel data technique a sample of 301 non financial firms was analyzed for the time period on five years starting from 2011 to 2015. We assert that effective risk capabilities have positive impact on all stakeholders. The effective risk management capabilities guarantee more resilience to exogenous and endogenous risks. Our findings will have a significant impact on existing literature, by extending the existing knowledge of firm’s risk management capabilities into the domain of diverse stakeholders and resources adjustment.
Role of the δ-Opioid Receptor in 2 Murine Models of Colitis

Published: January 2020

Crohn disease and ulcerative colitis, collectively referred to as inflammatory bowel disease (IBD), are chronic inflammatory disorders of the gastrointestinal tract. Currently, the etiology of IBD is unknown, and immunosuppressive therapies have become the standard of care to reduce
the inflammation; however, these agents only induce remission 50% of the time in patients and can have serious side effects. Recently, endogenous opioids and opioid receptors have been shown to play a role in the mediation of inflammation. In addition, opioid receptor blockade with a nonselective
antagonist, naltrexone, has been shown to reduce colitis in both murine models and human subjects. The goal of the current study was to determine if the antiinflammatory effects of naltrexone are mediated through the delta (δ) opioid receptor. Male C57BL/6NCrl (6 to 8 wk.; n
= 110) and female BALB/cAnNCrl (6–8 wk.; n = 91) mice were studied using 2 animal models of chemically induced colitis: dextran sodium sulfate (DSS) and 2, 4, 6-trinitrobenzenesulfonic acid (TNBS). The selective δ-receptor antagonists naltrindole and 7-benzylidenenaltrexone
were administered to examine the role of the δ-opioid receptor in colonic inflammation. The quantitative measurement of colitis activity, colon weight and length, Hct, WBC count, and gross and microscopic aberrations were analyzed. Administration of naltrexone in the DSS colitis model
significantly improved overall disease activity indices on day 5 of therapy. The use of δ-antagonists and naltrexone had limited to no effect on TNBS colitis. Similar findings were obtained by using the DSS colitis model. Based on the current findings, the authors conclude that naltrexone
therapy has limited effect on the improvement of colitis in 2 murine models; however, the δ-opioid receptor was not responsible for mediating the effects.

NHP are important translational models for understanding the genomic underpinnings of growth, development, fetal programming, and predisposition to disease, with potential for the development of early health biomarkers. Understanding how prenatal gene expression is linked to pre- and
postnatal health and development requires methods for assessing the fetal transcriptome. Here we used RNAseq methodology to analyze the expression of cell-free fetal RNA in the amniotic fluid supernatant (AFS) of vervet monkeys. Despite the naturally high level of degradation of free-floating
RNA, we detected more than 10,000 gene transcripts in vervet AFS. The most highly expressed genes were H19, IGF2, and TPT1, which are involved in embryonic growth and glycemic health. We noted global similarities in expression profiles between vervets and humans, with
genes involved in embryonic growth and glycemic health among the genes most highly expressed in AFS. Our study demonstrates both the feasibility and usefulness of prenatal transcriptomic profiles, by using amniocentesis procedures to obtain AFS and cell-free fetal RNA from pregnant vervets.
Teacher education cultural diversity, social justice and equality: Policies, challenges and abandoned possibilities in Swedish teacher education
Authors: Beach Dennis
Published: January 2020

There is a history of policies from the late 1940s to 2000 for the introduction of research based knowledge in Sweden for supporting the intellectual preparation of future teachers for an integrated and inclusive school system. The development of these policies was initiated following the National School Commission Inquiry into the possibilities for a common unitary comprehensive school, which had identified the historical divisions (duality) in teacher education as an obstacle. Pulling these divisions together and educating teachers in a shared content developed from a common research base in the education field about the challenges faced in the realization of the comprehensive school vision was expressed as a possible solution. However, the project failed. The divisions have remained. Schools have not overcome social reproduction. And in recent decades challenges have intensified as hyper-diversity, globalization and a recent turn towards market governance have added new complications.

Published: January 2020

La formación de futuros y futuras docentes, capaces de responder a las necesidades de justicia social en la escuela, constituye un reto en las instituciones de Educación Superior. La intención de este artículo es identificar cuáles son las acciones desarrolladas por el profesorado universitario para formar futuros y futuras docentes capaces de responder a las necesidades de todo el alumnado. El estudio se basa en una investigación etnográfica crítica llevada a cabo con tres profesores y 300 estudiantes del Grado en Educación Primaria en la Universidad de Zaragoza. Relatos de vida, observación participante en el aula universitaria y análisis de documentos han sido las técnicas utilizadas. Los resultados destacan dos acciones básicas que el profesorado universitario lleva a cabo para formar futuros y futuras docentes capaces de responder a las necesidades de todo el alumnado. (1) El diálogo en torno al conocimiento científico a partir de las experiencias de los estudiantes. (2) El desarrollo de procesos de deconstrucción y reconstrucción durante la enseñanza/investigación. Finalmente, el artículo discute el valor de la conexión entre investigación y enseñanza para posibilitar el empoderamiento de los futuros y las futuras docentes para dar respuesta a las necesidades de la escuela actual desde la justicia social.
