Türkçenin Yabancı Dil Olarak Öğretiminde Kişi Ad ve Soyadlarının Sınıflandırılması ve Okuma Metinlerinde Kullanımı
Authors: TUM Gulden
Published: November 2018

Yabancı dil olarak Türkçe (TYD) öğretiminde kelime öğreniminin zor olma
nedeni, farklı diller arasındaki sözcüklerin biçimsel özellikleri ile Türkçenin
sondan eklemeli bir dil olmasından kaynaklanan yapım ve çekim eklerinin farklı yapılandırılması
gösterilebilir. Her ikisi de anlamayı ve üretimi zorlaştıran unsurlardır.  Söz varlığının kolay ve kalıcı
öğrenilebilmesi sözcüklerin bilişsel düzeye hitap etmesi kadar anlamsal
metinlerin oluşturulmasına da bağlıdır. Bunun için metin ve metni oluşturan
sözcüklerin arasındaki bağın güçlü olması beklenir. Türkçede kişi adları farklı
anlam taşıyan sözcük gruplarında hazırlanabilir ve bu özellik yabancı
öğrencilere sezdirilirse öğrenmeye katkıda bulunulabilir. Bu çalışma, kişi ad
ve soyadlarının sınıflandırılması, okuma metinlerinde kullanılması ve
örüntülenmesi durumunda kalıcı öğrenmeyi ne kadar sağlayabileceğini
sorgulamaktadır. Bu nedenle Türkçenin yabancı dil olarak öğretimi dersini alan
öğretmen adaylarına kişi ad ve soyadlarını sınıflandırmaları ve sınıflandırmaya
göre metin üretmeleri istenmiş, hangi adları ne tür metinlerde kullandıkları
belirlenmeye çalışılmıştır. Ayrıca, kişi ad ve soyadlarının TYD kitaplarındaki
durumu da gözden geçirilmiştir. Sonuçlar öğretmen adaylarının kişi adlarını
sınıflandırmada doğa, duygu, kahramanlık, mevsim, din, sayı, eylem, sıfat
unsurlarını kullandıklarını ancak metin üretmede kişi ad ve soyadlarından
yeteri kadar yararlanamadıklarını; TYD kitaplarındaki kişi ad ve soyadı
kullanımlarının sınıflandırma ve biçim açısından yeterli olmadığını
göstermiştir. Bu alanda çalışmaya rastlanmamış olmasının alana katkıda
bulunacağı varsayılmaktadır.

Čokan Valichanov, l’identità nazionale kazaka e la colonizzazione russa
Authors: Citati Dario
Published: November 2018

Čokan Čingisovič Valichanov (1835-1865) has been one of the most significant personalities in Kazakh culture of 19th century. This article aims to examine three items of his intellectual production that highly, although subtly, influenced the self-identification of contemporary Kazakhstan after its independence from Soviet Union: the ambiguous relationship with Russian world, the admiration toward the West, the interpretation of Islam as a cultural element of the steppe rather then the key religious system of Kazakh people. As a result, Valichanov appears not only as a great polymath of the past, but as a constant ideological reference for today’s Kazakhstan.
Dipendenza e interdipendenza tra paesi land-locked e di transito
Authors: Frappi Carlo
Published: November 2018

The article aims at investigating the nexus between the land-locked condition and the energy security needs of a hydrocarbons-exporting country. Addressing the bilateral relations between Azerbaijan and Georgia, the article looks at the dynamics of dependence naturally unfolding between a land-locked country and its main transit one. Introducing the elements which may provide the land-locked country with a sounder bargaining power vis a vis its transit country, the article will focus on the tools exploited by Baku in order to reduce the asymmetry of power ensured to Georgia by its role of ‘window to the West’ for Azerbaijani national hydrocarbons. Findings suggest that the Oil & Gas sector provides land-locked country with effective tools enabling it to downgrade the vulnerability vis a vis transit country and to foster functional interdependence with the latter.

Authors: Dockery Michael , Logunov Dmitri V.
Published: November 2018

The lepidopterans in Raymond Wooff`s collection in the Manchester Museum are distinctively curated and represent an assemblage of insects in the classic Aurelian tradition but created in the twentieth century. This collection was established on index cards, with only butterfly/moth
wings being mounted and laminated onto cards. Despite being such an unusual collecting and preservation technique, it illustrates how a dedicated field biologist, with limited resources, can amass a significant, data-rich Lepidoptera collection that provides reliable information on distribution,
habitat preferences and phenology of the collected species. The present paper explores the history and content of this unusual Lepidoptera collection and its collector.

Authors: Amaral Ernesto F. L. , Faustino Samantha Haussmann Rodarte , Gonçalves Guilherme Quaresma , Queiroz Bernardo L
Published: November 2018

Brazil experienced population ageing and improvement in educational attainment between 1980–2010. Proportion of workers in the formal economic sector increased between 2000–2010. Earnings decreased from 1980 to 1991 and increased in 2000. However, earnings in the formal economic sector decreased again in 2010. We estimate associations of individual- and area-level variables with individual earnings of male workers living in urban areas in Brazil. Ordinary least squares regressions estimate variations on earnings of male workers, using the 1980–2010 Demographic Censuses. Individual independent variables include age, education, economic sector, race/color, marital status, religion, and region of residence. Contextual independent variables consider demographic, educational, and economic sector compositions by areas of residence. Considering individual-level variables, older and better educated workers have higher earnings. Workers in the formal economic sector have higher earnings than in the informal sector. For area-level variables, higher proportions of people working in the formal economic sector have positive associations with earnings. Proportions of people in age-education groups have negative associations with earnings mostly among older workers. For models by economic sector, proportions in age-education groups have higher positive coefficients in the informal sector, compared to the formal sector. Transitions in demographic, educational, and economic sector compositions are correlated with earnings. These effects generate greater economic inequality in the informal sector than in the formal sector. Our main contribution is the estimation of models about associations of individual earnings with individual and area-level variables, which can be replicated for other countries.

Published: November 2018

Contemporary academic culture is sometimes referred to as hypercompetitive and biased towards quantitative output indicators. This may induce a high level of perceived publication pressure, which can have detrimental effects on both science and scientists. Our research question was: What is the level of perceived publication pressure in the four academic institutions in Amsterdam and does the pressure to publish differ between academic ranks and disciplinary fields? We sent out the revised Publication Pressure Questionnaire (PPQr) to all academic researchers in Amsterdam. The PPQr is a validated instrument with 3 subscales (Publication Stress, Publication Resources and Publication Attitude) scored on Likert scale from 1 (totally disagree) to 5 (totally agree). 1073 researchers completed the questionnaire (response rate 14%). Postdocs and assistant professors (M= 3.4) perceive more publication stress than associate and full professors (M= 3.0) as well as PhD students (M= 3.2). PhD students (M= 2.4) perceive a greater lack of resources than associate and full professors (M= 1.8). Results indicate that publication pressure is perceived by researchers from all academic ranks and disciplinary fields. Yet publication pressure seems to be especially a strong stress factor for postdocs and assistant professors. Our findings emphasize the need for a healthier publication climate, where researchers are encouraged to put more emphasis on the quality and the integrity of their work.

Geographical Roots of the Coevolution of Cultural and Linguistic Traits
Authors: Galor Oded , Özak Ömer , Sarid Assaf
Published: November 2018

This research explores the geographical origins of the coevolution of cultural and linguistic traits. It establishes the existence of common roots for: (i) the presence of sex-based grammatical gender and the prevalence of gender bias, (ii) the existence of politeness distinctions and power distance, and (iii) the structure of the future tense and long-term orientation. The study documents that geographical characteristics that generated gender gaps in agricultural productivity, and led to gender bias in society, fostered the existence of sex-based grammatical gender. Further, ecological diversity, and its effect on the formation of hierarchical societies and the rise in power distance, were conducive to the emergence of politeness distinctions. Finally, higher caloric crop return, and its impact on long-term orientation, contributed to cross-language variations in the structure of the future tense.
Old and Out? A social network approach towards age, self-responsibility, and their effects on employability
Authors: Froehlich Dominik Emanuel
Published: November 2018

The share of older people on the workplace is increasing and thereby also the dependence of organizations on older employees rises. However, at the moment, older people are in general not well integrated into the workforce. This stresses the need for continuous learning in order to stay employable also in higher ages.Unfortunately, several factors limit the learning potential of older people in practice. Next to a decline in fluid intelligence, several negative stereotypes about old people exist on the workplace, especially in connection with learning and change. Empirical findings about age and learning on the workplace are inconsistent and give little guidance. We therefore aim to take a fresh look on the learning of older employees and focus especially on personal antecedents (goal orientation and future perspective) and the feedback exchange behavior of employees employing a social network analysis approach. Specifically, we hypothesize an effect of chronological age on goal orientation, which is partially mediated by future time perspective. A learning goal orientation and a open future time perspective are in turn hypothesized to be positively related to formal and informal learning (feedback seeking), which will eventually increase employability.After the basic model has been validated in different sectors and countries, a longitudinal field-study will be conducted in order to get a even more detailed look on the learning processes at the workplace.
Half a century of IgA nephropathy: achievements, frustrations and challenges
Authors: Lapchynska I.I.
Published: November 2018

IgA nephropathy is the most common glomerulonephritis worldwide. This disease has a tremendous economic impact because renal replacement therapy is expensive and hard-to-reach. It also represents a social problem because children and young adults in their second and third decades of life are affected by the IgA nephropathy, and it is the most active period of human life with highest work productivity. Many retrospective studies have shown that 40% of biopsy-proven IgA nephropathy patients develop end-stage kidney disease in 20 years after their biopsy disease.

The biomarker research in IgA nephropathy has experienced a major splash in recent years with great number of scientific reports. Individual biomarkers often lack sensitivity and specificity with impairment of disease specificity as a consequence. The review describes a novel approach based on a panel of biomarkers for pathogenic process of IgA nephropathy. Integration of genetic, clinical, and bioinformatics data sets could optimize the specific value of each biomarker in a multimarker panel. This is a inspirational and promising approach for precision medicine and personalized therapy in IgA nephropathy.

Half a century into the original description of IgA nephropathy, there is still no specific therapy for this condition Although the scarcity in treatment advances could be related to the disease’s complex pathogenesis. The evolution of different therapeutic approaches is reviewed over time and resulted in the 2012 Kidney Disease: Improving Global Outcomes Clinical Practice Guideline for Glomerulonephritis that presently is being updated, and provide collation of recent data on various forms of immunosuppressive agents. Existing approaches to treatment of IgA nephropathy are described with focus primarily on innovative therapeutic strategies currently being evaluated in IgA nephropathy that were not discussed in the 2012 Kidney Disease Improving Global Outcomes Clinical Practice Guidelines.

Authors: Colley Paige , Myer Bronia , Seabrook Jamie , Gilliland Jason
Published: November 2018

The quality of children’s diets has declined over the past few decades, giving rise to a variety of health-related consequences. In response to this trend, school food programs have become an increasingly effective method to support nutrition and lifelong healthy eating habits. This systematic review synthesizes current academic literature pertaining to school nutrition programs in Canada to identify existing interventions and their impacts on children’s nutritional knowledge, dietary behaviour, and food intake. The review was conducted through a search of the following databases: ERIC, Education Source, CINAHL, PubMed, SagePub, SCOPUS, EMBASE, and CBCA. Information extracted from the articles included the program objectives, intervention design and components, research evaluation, and primary outcomes. A total of 11 articles evaluating Canadian school nutrition programs were identified. The programs incorporated a variety of intervention components including policy, education, family and community involvement, and/or food provision. These multi-component interventions were positively associated with children’s development of nutrition knowledge, dietary behaviour changes, and intake of healthy foods; however, barriers associated with intervention duration, intensity, and availability of resources may have influenced the extent to which these programs impacted children’s diets and overall health.

Authors: Podnebesnykh P. A. , Ovchinnikov V. P.
Published: November 2018

The paper reviews the new data on the secondary zeolite mineralization characteristics for the Lower Cretaceous deposits of the West Siberian plate north. The authors suggest that the zone of distribution of altered rocks is much wider and in addition covers the area of Russkoye field. A new method of accounting of the volume of minerals of the zeolite group is proposed based on using the value of the volume fraction content of zeolites, which allows for a more qualitative approach to calculation of volumes of hydrocarbons in this type of reservoirs. It is shown that in major foreign deposits, complicated by the zeolitization processes, in order to improve the performance of the bottom-hole zone it is recommended to use a solution of hydrochloric acid.

Published: November 2018

Using the NMR method with a pulsed magnetic field gradient the features of crude oil self-diffusion were investigated on samples of oil from the Tula horizon, the oil field Yamashinskoye. It was found that the samples were characterized by a complicated (non-exponential) form of diffusion attenuation of the NMR spin echo amplitude which required the introduction of the concept of effective (average over the entire sample volume) coefficient of selfdiffusion Deff. The temperature dependences of Deff within the temperature range 303-363 K are satisfactorily described by the equation of Arrhenius type equation which enabled to determine the values of self-diffusion activation energy ED in the studied systems. The correlation between the parameters of the studied systems self-diffusion, Deff, ED and their dynamic viscosity was found.

Authors: Ovchinnikova S. V. , Ali G. H.
Published: November 2018

The ultimate goal of this work was to develop a method which can be used in mature oil fields to determine the effective viscosity of the granulated gel (PPG) used for plugging the anthropogenic fractures (after FHF). Using the laboratory fracture model the values of constants (apparent constant consistency, ka, and the apparent index of pseudoplasticity, na) were obtained for the equation of viscoelastic liquid. The same constants were used in the derived equation for pressure gradient along the artificial fracture. The gel effective viscosity was calculated based on the equation of the gel motion along the fracture. This equation enables to calculate the effective viscosity of PPG for each size the granulated gel fraction depending on the fracture width and the gel injection rate.

Published: November 2018

The article considers a vibrator of two-equalizer design used for pulsed liquid injection into a well. The versatility of this vibrator is the ability to provide a free delivery of geophysical instruments to the bottom of the well to be treated without pulling out the tubing string. Based on the mathematical expressions and taking into account the simulation results the basic expressions for determination of main parameters of the device operation are presented. Using a developed laboratory bench the tests of the pilot design have been run reproducing the downhole conditions. The comparison of the theoretical and laboratory results showed the error of no more than 16 %. Based on the results of bench tests the device optimal size was determined for achieving the expected effect at pulse injection of fluids into the well.

Published: November 2018

Currently, the most powerful and energy-intensive method of influence on the productive strata is water flooding. Due to certain economic factors, dictated by saving of capital costs on drilling of injection wells, a number of injection wells is much smaller than the development wells number. It is natural, that for full-value compensation of volumes of produced liquid from the development wells, taking into account losses, it is necessary to pump large volumes of water which can reach 1000-2500 m3 per day into a less number of injectors. Such conditions of water flooding lead to a need to create high pressure at the bottomhole and repression in the injection wells, which contributes the unfocused hydraulic fracturing. The results of the scientific research performed by S. I Grachev and A. S. Trofimov in a number of known fields using the method of tracer studying have shown that in all fields, where such studies were conducted, there observed the so-called channels with ultra-low hydraulic resistance, or with ultra-high conductivity/ permeability.

The complex flows of viscous compressible heat-conducting gas arising during heating the vertical field, have a pronounced axial symmetry. Therefore, for the numerical solution of the complete Navier-Stokes equations system to describe such gas flows it is advisable to use a cylindrical coordinate system. This paper describes a transformation of the second projection of the motion equation of the complete Navier-Stokes equations system. The result of this transformation is writing of the second projection of the equation of a continuous medium motion in the cylindrical coordinate system.
