Authors: ÇARPAR Mehmet Can
Published: August 2020

Sosyal bilimleri ve sosyolojiyi etkisi altına alan pozitivizmin sorgulanması sonucunda, insanı anlamaya ve onu kendi bağlamı içinde yorumlamayı amaçlayan niteliksel araştırma yöntemleri önem kazanmaya başlamıştır. Söz konusu araştırmalar birbirlerinden farklı ve özgün yönlere vurgu yaparlar. Bunlar, temel özellikleri bakımından genellikle etnografi, fenomenoloji, kuram oluşturma, anlatı araştırmaları ve durum çalışmaları şeklinde beş desene ayrılırlar. Bilindiği üzere bu desenler araştırmacının odaklandığı konuya, iletişim ve yazma kabiliyetine ve/veya sahip olduğu imkanlara göre farklılaşan süreçlere sahiptirler. Bununla birlikte söz konusu desenler nicel desenlerin aksine çok daha esnektirler ve esnek oldukları ölçüde iç içe geçen, karmaşık ve ayırt edilmesi zor aşamaları içerirler. Bu doğrultuda bu çalışmanın amacı sosyolojide son dönemlerde sıklıkla tercih edilen iki niteliksel desen olan fenomenolojik ve etnografik araştırmaların temel özelliklerini alanyazına dayalı olarak karşılaştırmalı bir biçimde analiz etmek ve söz konusu desenleri kullanacak biz araştırmacılara çok küçük de olsa bir katkı sağlamayı ummaktır. Bu derlemede öncelikle nitel araştırmaların karakteristik özelliklerinden bahsedilmiş, ardından fenomenolojik ve etnografik araştırmaların sosyal bilimlere etkileri, araştırmacılara katkıları, avantajları ve dezavantajları bakımından kısa bir analizi yapılmıştır.

Determining the Tangential Velocity profile of a Rotating Fluid in a Static Container using Navier–Stokes equations
Authors: TAH RAJDEEP , MAZUMDAR SARBAJIT , Parida Krishna Kant
Published: August 2020

The shape of the liquid surface for a fluid present in a uniformly rotating cylinder is generally determined by making a Tangential velocity gradient along the radius of the rotating cylindrical container. A very similar principle can be applied if the direction of the produced velocity gradient is reversed, for which the source of rotation will be present at the central axis of the cylindrical vessel in which the liquid is present. Now if the described system is completely closed, the angular velocity will decrease as a function of time. But when the surface of the rotating fluid is kept free, then the Tangential velocity profile would be similar to that of the Taylor-Couette Flow, with a modification that; due to formation of a curvature at the surface, the Navier-Stokes law is to be modified. Now the final equation may not seem to have a proper general solution, but can be approximated to certain solvable expressions for specific cases of angular velocity.

Dataset: Does loneliness, self-esteem and psychological distress correlate with problematic internet use? A Bangladeshi survey study
Authors: Mamun M. A. , Hossain Sharif , Moonajilin Mst. Sabrina , Masud Mohammed Tanvir , Misti Jannatul Mawa , Griffiths Mark
Published: August 2020

Background: Researchers have claimed that problematic internet use (PIU) and internet addiction (IA) is a global mental health problem. However, little research has addressed this issue in Bangladesh and no previous study has examined the relationship between PIU and potential psychological risk factors.Aim: The present study examined the prevalence of PIU and its associated risk factors including socio-demographic variables, internet use behaviors, and other psychological variables including loneliness, self-esteem, and psychological distress.Methods: A cross-sectional study was conducted among Bangladeshi students (N = 605). Measures included the Internet Addiction Test (IAT), Rosenberg's SelfEsteem Scale, the UCLA Loneliness Scale, and the General Health Questionnaire.Results: Using a cut-off score of ≤60 (out of 100) on the IAT, the prevalence of PIU was 16.5% (n = 100). Regression analysis showed that sleep disturbance (more or less than 6-7 hours sleeping time), not using internet for academic purposes, and online chatting were risk factors for PIU. Loneliness and psychological distress were positively correlated with PIU, whereas self-esteem was negatively correlated.Conclusions: The present study highlights that PIU among Bangladeshi university students is an issue of concern and that targeted prevention is needed among emergingadults to help overcome the potentially negative effects of problematic internet use.
On the Differences between General Cross-Lagged Panel Model and Random-Intercept Cross-Lagged Panel Model: Interpretation of Cross-Lagged Parameters and Model Choice
Authors: Usami Satoshi
Published: August 2020

Many methods have been developed to infer reciprocal relations between longitudinally observed variables. Among them, the general cross-lagged panel model (GCLM) is the most recent development as a variant of the cross-lagged panel model (CLPM), while the random-intercept CLPM (RI-CLPM) has rapidly become a popular approach. In this article, we describe how common factors and cross-lagged parameters included in these models can be interpreted, using a unified framework that was recently developed. Because common factors are modeled with lagged effects in the GCLM, they have both direct and indirect influences on observed scores, unlike stable trait factors included in the RI-CLPM. This indicates that the GCLM does not control for stable traits as the RI-CLPM does, and that there are interpretative differences in cross-lagged parameters between these models. We also explain that including such common factors as well as moving-average terms in the GCLM makes this interpretation very complicated.
Sinking in: the peripheral Baldwinisation of human cognition
Authors: heyes cecilia , Chater Nick , Dwyer Dominic Michael
Published: August 2020

The Baldwin effect is a hypothetical process in which a learned response to environmental change evolves a genetic basis. Modelling has shown that the Baldwin effect offers a plausible, elegant explanation for the emergence of complex behavioural traits but there is little direct empirical evidence of its occurrence. Here we highlight experimental evidence of the Baldwin effect and argue that it acts preferentially on peripheral rather than central cognitive processes. Careful scrutiny of research on taste aversion and fear learning, language and imitation, indicates that their efficiency depends on adaptively specialised input and output processes – analogues of scanner and printer interfaces that feed information to core inference processes and structure their behavioural expression.
Culture primer
Authors: heyes cecilia
Published: August 2020

In this Primer, Cecilia Heyes explains how and why cultural evolutionists define culture. Social learning is ubiquitous in animals, it often produces group-typical behaviour, and more rarely yields improvement over generations. In humans, complex cognitive processes may be fruits rather than seeds of cultural selection.

Authors: Surdyanto Annas , Kurniawan Wiwit
Published: August 2020

The preparation of these critical reading modules uses a learning approach that also provides a focal point for the development of thinking skills. The approach used is CLIL (Content and Language Integrated Learning). This approach is not only emphasizes language skills (language) but how learning content can provide a stimulus to think and understand what is the purpose of learning.CLIL is a teaching approach where students are taught in a foreign language with a dual focus which is the material being taught and language skills. In other words, the teacher can focus the discussion on specific themes and issues while still improving students' language skills. Themes and issues designed in learning will provide materials that can be used by students to develop a critical reading process. With a variety of themes from relevant and interesting literary works, students are required to not only seek information but analyze, evaluate and criticize the theme. In this aspect, CLIL will be relevant as an approach to develop practical, effective and valid Critical Reading modules for English Literature Department.

A metaphysical duel. Understanding Chekhov
Authors: Kantor V. K.
Published: August 2020

The article, based on the analysis of Chekhov’s The Duel [Duеl], offers a new interpretation of Chekhov’s oeuvre. Modern Chekhov studies often imply that the writer lived in the era of the end of ideologies and therefore refrained from offering any ideological recipes. In fact, nearly each of Chekhov’s longer novellas debunked the nascent ideologies of the time. He warned of the perils of submission to an ideology, even though he could not predict which one would eventually dominate. Therefore, he critiqued each and every one of them. This is how ideology is tackled in his story The Black Monk [Chyorniy monakh] (an anticipation of detrimental Modernist ideas); in A Dreary Story [Skuchnaya istoria], these days often compared to the story of Faust; and in Ward No. 6 [Palata nomer shest], showing descent of normal people into insanity. Similarly, in The Duel, he depicted a proto-Nazi and Bolshevik, no less, in the character of Von Koren, who embraces Nietzsche’s worldview and will not hesitate to destroy an intellectual who crossed his path.
Foreword [Preduvedomlenie] to the unpublished collection of novellas by Botanist X.
Authors: Kobozev D. R. , Chayanov A.
Published: August 2020

The first publication of the complete Foreword [Preduvedomlenie] authored by the renowned Russian economist and writer A. Chayanov in the Russian language (1999 saw the publication of the French version). The piece is considered to be an inseparable part of his ‘Moscow Hoffmanniada.’ To illustrate the book, Chayanov invited the master of smallscale graphics A. Kravchenko, who later became a classic of the romantic tradition in Russian 20th-c. graphic art. The publication never happened, banned by Glavlit (the official Soviet censorship organ) in 1926, and the Foreword was archived. This Foreword was missing from all subsequent publications of Chayanov’s romantic novellas, although the commentators kept referring to the piece. The article seeks to correct the situation and draw the readers’ attention to the text, printed in full after the typewritten manuscript stored in GARF (the State Archive of the Russian Federation), upon elimination of typos and obvious inaccuracies, assuming that the Foreword is part and parcel of Chayanov’s ‘botanical Hoffmanniada.’
A humanized human. Evgenia Nekrasova
Authors: Pogorelaya E. A.
Published: August 2020

The article is devoted to E. Nekrasova, a contemporary writer, whose school novel Kalechina-malechina was short-listed for The Big Book Prize and The National Bestseller Award in 2019. Kalechina-malechina is analyzed as a specimen of the contemporary Russian crossover novel (which targets both adult and young audiences), highly popular in the West, but having trouble taking root in Russia – perhaps, because the genre suggests a polyphony not only in terms of the plot, but also psychology, whereas Russian literature of the 2000s – 2010s is predominantly monologic. Nekrasova, on the other hand, in her Kalechina-malechina and Sestromam, a collection of short stories, embraces the principle of the diversity of voices. Comparing Nekrasova’s work with another example of contemporary school prose, provided by B. Khanov’s Inconstants [Nepostoyannye velichiny], the author decides that the integrity of a text today is defined by its polyphonic quality, by the ability to hear a different opinion: the ability that some modern authors and even critics are badly lacking.
Acute Pancreatitis in Pregnancy: Three Case Reports
Authors: Lemdaoui N , Lemdaoui N , Abdelmoumene M , Mammouche S , Bataiche A , Satta S , Boutrid H , Rahmoune H. , Boutrid N.
Published: August 2020

Acute pancreatitis is a rare condition during pregnancy, with peculiar specificities and particular findings.
We report a series of 03 cases of pregnant women, treated for acute pancreatitis from 2016 to 2020. Their
average age was 34.33 years and the diagnosis was based on clinical-biological clues: epigastric pain with
strong elevation of lipasemia. Biliary etiology was confirmed in all patients initially by ultrasounds. Two
patients had benign pancreatitis of favorable evolution. The third patient presented with a clinically severe
pancreatitis and systemic inflammatory response syndrome, multiple organ failure syndrome with maternal
and fetal deaths. Treatment was mainly symptomatic (medical), followed by cholecystectomy after delivery.
Acute pancreatitis during pregnancy is a real threat for both the maternal and fetal prognosis and is a
differential diagnosis that must be kept in mind for prompt management.
New Validated Analytical Method for Determination of Simvastatin in Tablet Formulations by RP–HPLC
Authors: Ashour Safwan , Ashour Safwan , Omar Soulafa
Published: August 2020

RP–HPLC method has been developed and validated for the determination of simvastatin (SVS) in pure
form and in tablets. Fluvastatin sodium was used as internal standard. The determination was performed on
Nucleodur column C8 (250×4.6 mm i.d., 5 µm particle size); the mobile phase consisted of a mixture of
phosphate buffer solution (KH2PO4 0.05 M, pH 4.83) and methanol (20:80, v/v), pumped at a flow rate 1.0
mL min−1
. Analyte was monitored by UV detection at 230 nm. The mean retention times for fluvastatin and
simvastatin were about 4.40 and 9.00 min, respectively. The method was proved linear in the range of 3.5–
550.0 µg mL-1
and exhibited good correlation coefficient (r>0.9998) and excellent mean recovery (100.71–
102.18%). Very good limit of detection of 0.63 µg mL-1 was found for SVS. The method was validated
statistically and by recovery studies for linearity, precision, repeatability, and reproducibility. This method
was successfully applied to the determination of simvastatin content in four marketed brands from Syria. A
good agreement between this method with the pharmacopoeial method for the determination of simvastatin
in some real samples demonstrates that the proposed method is suitable to quantify simvastatin in
pharmaceutical formulations.

Published: August 2020

Emotional abuse in marital or committed couples has been reported differently in literature. There has been
a traditional theme that husbands are significantly more emotionally abusive toward their wives. This trend,
however, has been changing due to the social participation and educational uplift of women. The current
study intended to explore the prevalence and levels of emotional abuse among husbands and wives. The
study involved 177 husbands and 139 wives and administered the Multidimensional Measure of Emotional
Abuse to assess the levels of emotional abuse among the respondents. The findings revealed that husbands
felt significantly more emotional abuse from wives.

Published: August 2020

Purpose: The purpose of the study is to analyze the structure of mental disorders and social adaptation in
retired ex-combatants of the security forces.
Methods: 111 retired men, ex-combatants who sought medical care, were examined. There are two groups:
I: 56 people with identified mental disorders; II: 55 with pre-nosological mental health disorders.
Results: It is shown that the state of mental health of retired ex-combatants is characterized by severe
polymorphic mental disorders, especially those expressed in group I (organic, behavioural disorders,
substance use, schizophrenia, schizotypic and delusional disorders, affective, neurotic, stress-related, and
somatoform disorders, personality and behaviour disorders in adulthood), as well as social maladaptation,
associated with the transformation of values, lifestyle and communication, the emergence of difficulties in
social and everyday life, the breakdown of social ties and the displacement of pensioners from public life.
Conclusion: The article substantiates the need for a comprehensive approach to the rehabilitation of retired
ex-combatants with the interaction of all government structures, public associations, medical, psychological
and social institutions directly related to the development and implementation of individual rehabilitation
routes.
Acute Coronary Syndrome in Octogenerians: Management Perspectives
Authors: Modi Ranjan , Modi Sunil , Modi Ranjan
Published: August 2020

Current guidelines for acute coronary syndrome are derived from the data in randomized clinical trials and
metanalysis conducted in patients. These patients are generally of younger age. The data of acute coronary
syndrome in octogenarians is mainly derived from registries. This mid and long-term data regarding medical
therapy or interventions in octogenarians is low in number with smaller subsets of patients. Most of the
physicians are reluctant to use the same guidelines in these elderly patients due to increased chances of
complications. This article reviews the available data and literature in acute coronary syndrome in
octogenarians and provides management perspectives for these elderly patients.
Complementary Correlational Profiles between Slow Wave Brain Oscillations and Working Memory Capacity
Authors: Davelaar Eddy J. , Davelaar Eddy J.
Published: August 2020

Working memory involves a range of functions, including maintenance of information and processing that
information undisturbed by distraction. Neuroscientific studies have observed critical contributions from
frontal and parietal brain regions during processing of cognitive demanding tasks. However, less is known
about individual differences in the resting state and their association with working memory capacity. In this
study, electrophysiological recordings were taken from thirty volunteers in eyes closed and eyes open
conditions after completing the automated version of the operation span task. The results reveal two clusters
of correlations: a midline-theta cluster and a parieto-temporal alpha cluster. The theta and alpha clusters
have a negative and a positive correlation with operation span performance, respectively. These results are
interpreted as individual differences in cognitive preparedness, with the centro-parietal region being critical
in switching between outward and inward attention, with the balance of theta and alpha spectral power at
Pz indicating to where cognitive resources are directed.

As a renewable energy, ocean wave energy is exploited with infinite potential to solve the energy crisis. In this study, we develop a novel two-body direct-drive wave energy converter (DD-WEC) to surmount the problems associated with low power density, low direct-drive speed of the buoys, seawater corrosion and maintenance in the existing two-body WEC. Its prototype consists of two cylindrical buoys that float horizontally at sea level and the Halbach permanent magnet linear generator (HPMLG) that is employed in the power take-off (PTO) system. The energy is extracted from the relative motion between two buoys oscillating. Compared with the existing WEC, the proposed WEC has more vigorous motion between buoys, higher conversion efficiency and little extra underwater structure, due to the utilization of the horizontal buoys and the HPMLG. First, the motion equations of buoys are derived on the basis of linear wave theory. And depending on the motion equations, the structure of buoys and the HPMLG is designed. And we found that compared with the existing WEC, the proposed WEC has more vigorous motion between buoys in the seawater waves oscillation. Then, based on finite-element method (FEM), the performance of the HPMLG is evaluated, and it can generate 19% more power than the traditional permanent magnet linear generator (TPMLG) based on the same wave motion. Finally, the DD-WEC prototype is manufactured based on the designed parameter. The manufactured prototype is tested in the test platform and the wave tank. The measured output voltage is highly consistent with the observed variation trends in FEM simulation data. The results show that the proposed DD-WEC is well suited for wave energy conversion.
Design and analysis of metamaterials for wireless power transfer with same resonance frequency but different L/C combinations

Published: August 2020

Metamaterial is an artificial material with unique material properties that cannot be found in a naturally existing one, and hence it is able to perform functions that a conventional material cannot do. Consequently, it has shown great potential in various engineering applications such as resonance coupled mid-range wireless power transmission (R-WPT) systems. However, the analysis and design of an application-oriented metamaterial include both the unit cells and their combinations, and thus are very complex. Moreover, the performance of a metamaterial is very sensitive to uncertainties in both manufacturing and operating conditions. In this regard, a two-phase methodology for robust design optimizations of metamaterial slabs in R-WPT applications is proposed and applied to the design optimization of a prototype R-WPT system with promising results.

The laser array spot thermography (LAST) is a fully non-contact and non-destructive method for the inspection of surface cracks with high efficiency. In this study, the detection capability of this method for the inspection of surface cracks in structures with curved surfaces is experimentally studied. The influence of the inspection angle on the crack imaging results is also investigated. The experiment results show that cracks in surface of the pipes with different dimeters can be detected and imaged by LAST.

This paper presents a multi-parameter model of an ultrasonic motor for speed control. Firstly, the model is divided into the steady-state part and the dynamic part, and then the speed mapping relationship of amplitude, frequency, phase difference is described by linear function, exponential function, and hyperbolic tangent function, respectively in steady-state modeling. The least-square transfer function identification is used in the dynamic velocity modeling. This paper also constructs a modeling flowchart from the discrete models to the state-space function based on the pairwise combination of parameters, which can realize the flexible control of different parameters. Finally, the error box diagram of the model and the comparison between the measured results and simulation ones both verify the effectiveness of the model.
Fast reconstruction of the magnetization of a Halbach magnet in EMAT using experimental measurements
Authors: Mihalache Ovidiu , Yamaguchi Toshihiko
Published: August 2020

The paper presents a fast and accurate algorithm to reconstruct the magnetization model of parallelepiped magnet (parts of a Halbach magnet array) or the Halbach magnet array used in an electromagnetic acoustic (EMAT) transducer. The model accuracy is validated against measurements of the magnetic flux distributions above surface of block magnets or Halbach magnet array using 2D/3D theoretical formula to compute magnetic flux distribution, validated by 2D/3D FEM simulations, and based on a non-uniform distribution of reconstructed magnetization model (using only main magnetization component). The illness of inverse reconstruction model is controlled through very small enough increments steps in an adaptive iterative algorithm but large enough increments to assure faster reconstruction, and converging to the same magnetization model of magnet blocks or Halbach array magnet, independent of the initial magnetization values.

Published: August 2020

With the continuous development of society and economy, people’s demand for electric energy is increasing. The low-carbon and energy-saving technologies of renewable energy especially wave energy have become the focus of current researches. Considering the increasingly serious energy problems, a wave energy converter (WEC) is proposed based on Halbach permanent magnetic array, which increases the output performance. The equivalent magnetic circuit model of the WEC is established. The static magnetic field modeling and structural parameters optimal permanent of the WEC are performed on this theoretical. Theoretical studies have found that the optimal permanent magnet thickness ratios for Halbach permanent magnet array structures is 0.6, and the ratio of permanent magnet to coil radial ratio is 0.7. The coil winding form and rectifying circuit of the WEC were designed. The WEC equivalent magnetic circuit model was verified by COMSOL Multiphysics finite element software, and the open circuit voltages of WEC was obtained. If the WEC moves at a speed of 0.1 m/s, the coil voltage can reach about 113 V after simulation. According to the testing requirements of the WEC, a test platform was built. The Halbach permanent magnet array structures greatly enhances the wave energy collection of WEC.

Published: August 2020

For the electrical anisotropy of carbon fiber reinforced polymer (CFRP), conductivity of unidirectional CFRP laminate in three directions was inverted in this paper. The three-dimensional eddy current electromagnetic model of unidirectional composites was constructed by ANSYS software, and the influence of the electrical conductivity of the material on the detection signal of the probe in the longitudinal, transverse and thickness directions was studied. In order to improve the amplitude of the probe output signal induced by the change of conductivity, the optimal detection angle of the eddy current probe was determined. On this basis, the relationship between the conductivity and the detection signal was studied to estimate the initial values of the conductivity based on the experimental data obtained by the eddy current testing (ECT). According to the forward model, the theoretical probe voltage under the estimated conductivity were calculated. The database consisting of conductivity and corresponding theoretical results was built for the neural network to construct the mapping that can estimate conductivity by experimental results. Using neural network for iteration, the conductivity was inverted quickly and precisely.
Climate Change, Energy Security and Societal Vulnerability in Eurasia
Authors: Mohapatra Nalin Kumar
Published: August 2020

Climate change, energy security, and societal vulnerability are three normative frameworks providing a “context” to study the notion of “sustainable security”. Demand for “fossil fuel is growing”, hence, a greater concern for securing “cleaner energy” along with maintaining a “harmonious” and “sustainable environment” also exists. The present article attempts to highlight how to maintain a delicate balance between these two above-mentioned normative frameworks to ensure “sustainable security” in Eurasia. The important aspect that needs to be highlighted here is while in the Arctic and Siberian parts of Russia along with the Caspian Region, the energy sector is playing a catalytic factor for climate change, on the other hand, in parts of South Caucasus and along the Baltic, though energy is not a major factor, still they are experiencing climatic change with negative consequences. In Central Asia, however, climate change is putting a stress on “hydropolitics”, this, in turn, is aggravating the “societal insecurity” in terms of “accessibility” to hydro-energy. Henceforth, Eurasia requires a more sustainable and pragmatic policy framework in the context of addressing problems associated with the three above-mentioned normative trajectories.
