Changes in Physicians' Specalization Preferences from 1987 to 2017
Authors: BAKAN KALAYCIOĞLU Dilara
Published: November 2020

Aim: The purpose of this study is to determine whether gender is an associated variable in the speciality preferences of physicians and to investigate the change in the mean scores of the medical specialities according to the risk groups.
Methods: This study has been conducted in relational survey model and the dataset of the study consists Weighted Clinical Medical Sciences scores (K) of 18.308 physicians who placed in a medical speciality with the Medical Specialization Examinations applied in 1987, 1997, 2007 and 2017. Within the scope of the study, 2 test was used to determine whether there is a relationship between the gender of physicians and their speciality (internal, surgical, basic medical sciences) and medical malpractice risk groups (first, second, third and fourth). In addition, to investigate the changes occurring in the speciality preferences of physicians in the course of time, K score averages of the risk groups by years was examined by one way analysis of variance. Finally, the distribution of the one hundred physicians’ specialities with the highest K score is given year by year.
Results and Conculusion: There is a statistically significant relationship between physicians’ gender and the medical speciality which they were placed. In general, male physicians prefer surgery, while female physicians prefer internal and basic medical sciences. Similarly, there is a statistically significant relationship between the gender of physicians and the risk groups of their specialty. According to the variance analysis results, the differences between the standardized K score means of all risk groups were found statistically significant. In the forty-year period, especially the standardized K score means of the first risk group increased. When the 2007-2017 compared, the standard K score means of the specialties in the first and second risk groups increased, while the standard K score means of the specialties in the third risk group decreased. During the last 40 years, it has been observed that the physicians who scored high in the Medical Specialization Examinations tend towards to dermatology, plastic, reconstructive and aesthetic surgery, and radiology, rather than child health and diseases, internal medicine, gynecology and obstetrics, and cardiology. Based on these findings, the factors that cause physicians declining interest in surgical specialities should be determined and precautions should be taken.

Accuracy and Reproducibility of Host-Guest Interactions in Zeolites
Authors: Schwalbe-Koda Daniel , Gomez-Bombarelli Rafael
Published: November 2020

Molecular modeling plays an important role in the discovery of organic structure-directing agents (OSDAs) for zeolites. By quantifying the intensity of host-guest interactions, it is possible to select cost-effective molecules that maximize binding towards a given zeolite framework. Over the last decades, a variety of methods and levels of theory have been used to calculate these binding energies. Nevertheless, no benchmark examining these calculation strategies has been reported. In this work, we compare binding affinities from density functional theory (DFT) and force field calculations for 272 zeolite-OSDA pairs obtained from static and time-averaged simulations. We show that binding energies from the frozen pose method correlate best with DFT time-averaged energies. They are also less sensitive to the choice of initial lattice parameters and optimization algorithms, as well as less computationally expensive. Furthermore, we demonstrate that a broader exploration of the conformation space from molecular dynamics simulations does not provide significant improvements in binding energy trends over single-point calculations. The code and benchmark data are open-sourced and together with the reported results, provide robust, reproducible, and computationally-efficient guidelines to calculating binding energies in zeolite-OSDA pairs.

Методом спектрального анализа в дальнем (70 - 420 см) ИК-диапазоне исследовано влияние введения ионных групп на формирование сетки физических связей в композитах на основе полиэфир уретана и сополимера стирола. Анализ спектров ПУИ / Ст-со-АК (К+) композитов показал, что при увеличении содержания Ст-со-АК (К+) в системе образуется новая сетка межмолекулярных (ион-молекулярных) связей. Появление интенсивной полосы поглощения при ~ 180 см, обусловленной колебаниями катионов К+ в электростатической области анионов (СОО-) карбоксильных групп, её значительная полуширина и наличие максимумов при 145, 155, 177, 185, и 200 см свидетельствуют об образовании различных по организации форм катион-анионных ассоциатов в системе: от простых ионных пар до сложных мультиплетов и кластеров.

He effect of the introduction of ionic groups on the formation of a network of physical bonds in composites based on polyether urethane (PEUI) and styrene copolymer (S-co-AA (K+)) was studied by the method of spectral analysis in the far (70-420 cm) IR range. An analysis of the spectra of PEUI / S-co-AA (K+) composites showed that with an increase in the content of S-co-AA (K+), a new network of intermolecular (ion-molecular) bonds forms in the system. The appearance of an intense absorption band at ~ 180 cm, due to vibrations of K+ cations in the electrostatic region of anions (COO-) carboxyl groups, its significant half width and the presence of maxima at 145, 155, 177, 185, and 200 cm indicate the formation of various on the organization of forms of cation-anion associates in the system: from simple ion pairs to complex multiplets and clusters.

В работе рассмотрены перспективы введения второго металла-модификатора в состав палладий-содержащих катализаторов кросс-сочетания Сузуки. Представлены результаты проверки каталитических свойств моно- (Pd) и биметаллических (Au-Pd, Pd-Cu, Pd-Zn) безлигандных катализаторов на основе сверхсшитого полистирола марки MN100, содержащего третичные аминогруппы, в модельной реакции кросс-сочетания 4-броманизола и фенилбороновой кислоты. Реакция проводилась на воздухе в периодическом режиме в мягких условиях (растворитель - смесь этанола и воды в объемном соотношении 4 : 1, температура 60С, основание - NaOH) в отсутствии агентов фазового переноса. Было показано, что в случае образца Pd/MN100, предварительно восстановленного в токе водорода, для достижения 100% конверсии 4-броманизола за 60 мин важно обеспечить определенный избыток фенилбороновой кислоты и NaOH (селективность по продукту кросс-сочетания при этом сохраняется равной 89%). Среди биметаллических образцов наибольшей активностью обладал катализатор Au-Pd/MN100 (достигалась 100% конверсия 4-броманизола за 15 мин реакции), однако наиболее селективным был образец Pd-Cu/MN100 (селективность составила 93%).

This paper is devoted to the prospects of introducing the second metal-modifier into the composition of palladium-containing catalysts of Suzuki cross-coupling. The results of catalytic testing of mono- (Pd) and bimetallic (Au-Pd, Pd-Cu, Pd-Zn) ligandless catalysts based on hyper-crosslinked polystyrene of MN100 type containing tertiary amino-groups in the model reaction of cross-coupling of 4-bromanisole and phenylboronic acid are presented. The reaction was carried out in air in a batch mode under mild conditions (solvent - mixture of ethanol and water in a volumetric ratio of 4 : 1, temperature 60C, NaOH was used as a base) in the absence of phase-transfer agents. It was shown that in the case of Pd/MN100 sample preliminarily reduced in hydrogen flow, it is important to provide a certain excess of phenylboronic acid and NaOH in order to achieve 100% conversion of 4-bromanisole in 60 min (selectivity with respect to cross-coupling product was maintained at 89%). Among bimetallic samples, the catalyst Au-Pd/MN100 revealed the highest activity (100% conversion of 4-bromanisole was achieved in 15 min of reaction), however Pd-Cu/MN100 sample was the most selective (selectivity was 93%).

Servant and transformational leadership: a supply chain management perspective
Authors: Nichols Thomas , D. Anderson Trisha , Erakovich Rod
Published: November 2020

We examine the association between leadership style (transformational and servant) and the type of supply chain (efficient or responsive) and the impact of employee engagement on customer satisfaction. We propose a model for examining the influence of transformational and servant leadership on the efficient and responsive type supply chains. We present 7 propositions and present a novel view of leadership by viewing it through the lens of contextual leadership theory in which the context is defined by the type of supply chain, effective or responsive. While both transformational and servant leadership are viewed as positive, even normative, forms of leadership, we have found that the efficacy of each type of leadership can be influenced by the context in which they operate and especially in supply chain environments.

funded by the Fund for Assessment Research (FAR) in Foreign Language Education in China. Next, we will illustrate how some research questions can be answered by analyzing a video-taped lesson from a round-one FAR project. We conclude by calling for more teacher-led research and argue that research on CBFA by teachers will not only produce valid interpretations and applicable findings, but also constitute a viable model for teacher professional development.
Word meaning in academic English: homography in the Academic Word List
Authors: Ming-Tzu K. W. , Nation Paul
Published: November 2020

The Academic Word List (Coxhead 2000) consists of 570 word families that are frequent and wide ranging in academic texts. It was created by counting the frequency, range, and evenness of spread of word forms in a specially constructed academic corpus. This study examines the words in the Academic Word List (AWL) to see if the existence of unrelated meanings for the same word form (homographs) has resulted in the inclusion of words in the list which would not be there if their clearly different meanings were distinguished. The study shows that only a small proportion of the word families contain homographs, and in almost all cases, one of the members of a pair or group of homographs is much more frequent and widely used than the others. Only three word families (intelligence, offset, and panel) drop out of the list because none of their homographs separately meet the criteria for inclusion in the list. A list of homographs in the AWL is provided, with frequencies for those where each of the members of a homograph pair are reasonably frequent.
Identifying technical vocabulary
Authors: Chung T , Nation Paul
Published: November 2020

This study compared four different approaches to identifying technical words in an anatomy text. The first approach used a four step rating scale, and was used as the comparison for evaluating the other three approaches. It had a high degree of reliability. The least successful approach was that using clues provided by the writer such as labels in diagrams, typographical marking, and definitions. Using a technical dictionary was more successful, but had an accuracy rate around 80%. The fourth approach compared frequency of occurrence in the specialized text with frequency in a large more general corpus. This worked well, but failed to identify words like neck, chest, skin which were also in common usage. It also could not separate collocates of technical words (superior, posterior, transverse) from technical words. If collocates are included the accuracy rate is close to 90%. Being able to reliably identify technical vocabulary provides an essential starting point for looking at how learners and teachers should deal with technical vocabulary. © 2004 Elsevier Ltd.

Perception is Reality: Teachers' Perceptions of the Presence of Servant Leadership Characteristics in Public School Principals and its Influence on Teachers
Authors:   , Simmons Johnnie
Published: November 2020

This phenomenological study explored teachers’ perceptions of the presence of servant leadership characteristics in their school principals and how the principals’ use of servant leadership characteristics influenced teachers. The primary phenomenon was the teachers’ perceptions of their principals’ use of servant leadership characteristics based on their direct personal experiences with the principals and the intrinsic and extrinsic influence on their behavior. A nonrandom sample of 16 public school teachers from Grades 1 through 12 from three similar districts in a southern California county was recruited. The elementary, middle, and high school teachers participated in one-on-one semi structured interviews. The data from the 16 oral interviews indicated that principals’ use of servant leadership characteristics, as perceived by the teachers, intrinsically and extrinsically influenced the teachers. The interviews generated seven themes regarding perceptions held by the teachers regarding their principals’ use of servant leadership characteristics. When principals in public schools exhibit servant leadership characteristics, teacher satisfaction and retention are impacted. Therefore, consideration must be made for use of servant leadership as a framework and model for teachers’ perceptions of their principals’ use of servant leadership and how those perceptions influence teachers.

The analysis of the main characteristics of reproductive capacity of herd cows on a farm was performed during 2013–2018. The material of the research work was based on the informational database of animals from the program of breeding register Selex. Cows were divided according to sire lineage and milk productivity into five groups by the level of milk yield: from 5000 to6500 kg, 6501-8000, 8001-9500, 9501-11000 and more than11001 kg. Successful insemination of heifers took place at the age of 15.7-16.6 months with the live weight of more than400 kg, which corresponds to zootechnical standards. The earliest (15.7 months) insemination was in heifers of Reflection Sovereign sire line, the age of first calving was 753 days with the live weight of561 kg. The latest (498 days) successful insemination was observed in heifers of Montvik Chieftain bull line with the live weight of498 kg. Cows of Sealing Trygen Rocket (8766 kg) and Reflection Sovereign (8704 kg) sire lines had the highest milk productivity with a significant difference (p ≥ 0.90). The cows of these lines had the longest service period (164 and 179 days), as well as the length of the calving interval (445 and 458 days), respectively. The coefficient of reproductive capacity of cows of different sire lines ranged from 0.80 to 0.88, which is a low indicator.

The analysis of the therapeutic efficacy of a new medical and prophylactic drug on piglets of Large White breed crossed with Duroc was carried out. The experiment was conducted in the conditions of a pig-breeding farm in theTrans-BaikalTerritoryin 2019, 2020. Experimental animals were treated with a preparation based on dry extracts of magnolia vine, wild rose, bird cherry, chamomile, and eleutherococcus rhizomes. For the experiment, three groups of newborn pigs (n = 30) with signs of gastrointestinal tract disorders were formed. The drug was administered to piglets for 10 days according to two regimens: the 1st experimental group was given the drug orally at a dose of 6 ml/kg of live weight once a day; the 2nd experimental group – at a dose of 6 ml/kg of live weight 2 times a day with an interval of 12 hours. The control group was injected with a prebiotic at a dose of 10 ml/kg (1x106 CFU/10 mg) once a day. The animals were assessed on a daily basis for their clinical status (temperature, pulse, respiration, level of dehydration according to skin turgor, intensity of reflexes, state of feces). Recovery in the 1st group was observed on the 4th day, in the 2nd group on the 2nd day. The animals of the control group suff       a severe disease, the death rate was 60%, the surviving animals recovered on the 10th day. In animals of the 2nd group, there was an increase in lymphocyte cells by 34.5%, erythrocytes – by 18.1%, hemoglobin – by 8.1%, hematocrit – by 13.9%. The biochemical analysis of the blood serum of piglets showed a positive growth dynamics of total protein by 12.1%, albumin – by 17.1%, globulins – by 6.2%. The most effective regimen of treating pigs with the herbal preparation proved to be the one used in the 2nd experimental group. The use of the drug according to the recommended treatment regimen will allow pig farms to ensure high survival rate of young pigs, increase their weight gain and get environmentally friendly pig products.

The aetiological diagnosis in an infant with hypotonia is a challenging task for a clinician due to variable and long list of differentials [1]. It could be due to an insult within the central nervous system (CNS) or less commonly result from a peripheral defect at neuro-muscular level and other miscellaneous causes (rickets, hypothyroidism) [2]. Most commonly it is a central hypotonia where the muscular weakness is absent or not profound. In Indian scenario, it is mostly idiopathic central hypotonia, followed by HIE (cerebral palsy) [2]. In cases of cerebral palsy, neuro-imaging reveals the severity of affliction. The peripheral aetiologies like congenital myopathies, congenital myasthenia, infantile botulism etc. are rather rare occurrences. Infants with congenital muscular dystrophy have muscular dystrophy, central neural affliction and involvement of multiple systems (skeletal, cardiovascular, respiratory, ocular etc.). It is a rare disease with studies in Italian population showing point prevalence of 0.563 per 100,000 total population [3]. Unlike HIE, the affliction in CMD is multi-system and it is an inherited disease with variable penetration, the distinction between the two is important to a clinician for the management. CMDs generally have early fatal outcome. So, early diagnosis is important for prognostication, supportive treatment and genetic counselling. The neuro-imaging findings of CMD clearly stand out from the rest aetiologies and can guide a clinician to go in early , for an invasive test like muscle biopsy which is the gold standard diagnostic test .

Bu çalışmanın amacı, Avrupa Birliği üye ülkeleri ve Türkiye’de polis alımlarında kullanılan fiziksel uygunluk testlerinin mevcut uygulamalarının neler olduğunu analiz etmektir. Betimsel bir amaca yönelik tasarlanan bu çalışmada veriler, polis alımlarında yetkili kurumların internet sayfalarındaki işe alım ilanlarından tarama yöntemi kullanılarak elde edilmiştir. Elde edilen verilere göre, fiziksel uygunluk bileşenlerinden kas gücü/dayanıklılık ve kardiyovasküler dayanıklılık testlerini uygulayan ülkeler çoğunluktadır. Ayrıca, çeviklik/sürat ve koordinasyon/beceri testlerinin de tercih edildiği gözlemlenmiştir. Fiziksel uygunluk bileşenlerinden olmamasına rağmen yüzme testlerini uygulayan ülkeler de bulunmaktadır. Alanyazında el kavrama kuvvetinin tabanca atış isabet oranlarına katkısını ortaya koyan araştırmalar bulunmasına rağmen, ülkelerden sadece İtalya’nın el kavrama kuvveti testini polis alımlarında tercih ettiği tespit edilmiştir. Sonuç olarak, polis işe alımlarında temel seviyede fiziksel uygunluk bileşenlerinin tercih edildiği görülmektedir. Polis işe alımlarında, polislik mesleğine özgü becerilerin de değerlendirilmesinin eğitim maliyetlerinin azaltılmasına katkı sağlayacağı söylenebilir.
INTERNATIONAL MIGRANTS AS A MATTER OF SECURITY: OPEN DOOR POLICY AND SYRIANS IN TURKEY
Authors: KARAKOÇ DORA Zuhal
Published: November 2020

International migration, an issue as old as the history itself, needs to be tabled. The Syrian conflict which happened due to the Arab Spring led millions of Syrians to leave their country. The wave of uncontrolled immigration, starting from the neighbouring ones and spreading to various countries, became an important tool for terrorists to infiltrate into target countries and caused a serious security problem for migrant-hosting states. Additionally, this human flow has led to changes in the demographic structures of the hosting countries, and these changes have brought many social and economic costs that threaten the internal security. In this context; in Turkey, who applied open door policy for the people fleeing from the humanitarian crisis in Syria from the very first days, issues caused by Syrians in time are quite attention grabbing. An in-depth analysis of these events reveals the relationship between illegal and irregular migration and considerable increase in terrorist activities, social, political and economic costs and demographic changes.

İnsanlar tarihte önceleri iklim şartları nedeniyle yer değiştirmiş, yakın dönemde ise daha çok silahlı çatışmalar, işgaller, ayrımcılık, insan hakları ihlalleri gerekçeleri ile göç etmişlerdir. Göçler nedeni ile göç edenler ve yerleşikler karşılıklı birbirlerini etkilemiştir. Sosyal, kültürel, ekonomik, siyasal konulardaki etkiler yeni dönemin güvenlikleştirici ortamında göçün tehdit olarak algılanmasına yol açmıştır. 2011 yılında başlayan Arap Baharı ile Suriye’deki iç savaş Suriyelileri ülke içi ve dışına göç etmek zorunda bırakmıştır. 3.5 milyonu aşan Suriyeli’nin Türkiye’nin her şehrinde yaşıyor olması toplumda birçok alanda değişik algılara yol açmıştır. Bu çalışmanın amacı toplumun Suriyelilere yönelik sahip olduğu güvenlik algısını araştıran bir ölçek geliştirmektir. Fiziksel, sosyo-ekonomik ve kültürel ile siyasal güvenlik algısı boyutlarında yeni geliştirilen 35 sorudan oluşan ölçek; pilot uygulama sonrasında Gaziantep ve Balıkesir illerinde yaşayan 785 kişiye uygulanmıştır. Analizler sonucunda bu ölçeğin toplumun güvenlik algısını belirleyebilecek geçerli ve güvenilir bir araç olduğu söylenebilir.
Spin-Orbit Coupling Effect on the Electrophilicity Index, Chemical Potential, Hardness and Softness of Neutral Gold Clusters: A Relativistic Ab-initio Study
Authors: Jabbarzadeh Sani Mahnaz
Published: November 2020

Electrophilicity index (𝜔) is related to the energy lowering associated with a maximum amount of electron flow between a donor and an acceptor and possesses adequate information regarding structure, stability, reactivity and interactions. Chemical potential (μ) measures charge transfer from a system to another having a lower value of μ, while chemical hardness (η) is a measure of characterizing relative stability of clusters. The main purpose of the present research work is to examine the Spin-Orbit Coupling (SOC) effect on the behavior of the electrophilicity index, chemical potential, hardness and softness of neutral gold clusters Aun (n=2-6). Using the second-order Douglas-Kroll-Hess Hamiltonian, geometries are optimized at the DKH2-B3P86/DZP-DKH level of theory. Spin-orbit coupling energies are computed using the fourth-order Douglas-Kroll-Hess Hamiltonian, generalized Hartree-Fock method and all-electron relativistic double-ζ level basis set. Then, spin-orbit coupling (SOC) corrections to the electrophilicity index, chemical potential, hardness and softness are calculated. It is revealed that spin-orbit correction to the vertical chemical hardness has important effect on Au3 and Au6, i.e. SOC decreases (increases) the hardness of gold trimer (hexamer). Due to the relationship between hardness and softness, σ = , inclusion of spin-orbit coupling increases (decreases) the softness of Au3 (Au6) and thus destabilizes (stabilizes) it. Spin-orbit coupling (SOC) also has more important effect on the chemical potential of Au3 by decreasing its value. It is found that spin-orbit coupling has considerable effect on the electrophilicity index of gold trimer and greatly increases its value. Furthermore, SOC increases the maximal charge acceptance of Au3 more and thus destabilizes it more. As a result, spin-orbit coupling effect appears to be important in calculating the electrophilicity index of the gold trimer. Doi: 10.28991/HIJ-2021-02-01-05 Full Text: PDF
Challenges and Risks in the Due Diligence Process Answered with an Innovative Approach
Authors: Müller Christoph
Published: November 2020

In existing academic studies on the Due Diligence process, the different areas have been considered separately. This is time consuming and causes inefficiencies. The proposed approach to Due Diligence integrates these separate areas into one process. While every company’s success can be defined by a few key factors, these differ by industry. The goal of this analysis is to develop a basis for decision-making regarding Mergers and Acquisitions for small- and medium-sized manufacturing companies by generating a scorecard model that enables the potential acquirer to perform an overall analysis of the existing data as well as to generate an informed outlook for the future using a standardized and efficient approach that also has a positive impact on the success rate of mergers and acquisition transactions. The model is based on different research methods. First of all, a literature research was executed, to define the theoretical framework. There are two main areas, the Strategic Controlling on the one hand and M&A on the other hand. The theoretical findings are specified through expert interviews. The expert interviews are semi-standardized. There is a quantitative and a qualitative part. Based on the analysis, a concept for a leaner DD approach is developed. The article presents a sum up of the research. Doi: 10.28991/HIJ-2021-02-01-06 Full Text: PDF

Published: November 2020

A tendência atual dos movimentos de Acesso Aberto e de Ciência Aberta na promoção da informação científica pode tornar possível a criação de um repositório de dados científicos na Universidade Federal de Alagoas, considerando dados científicos o foco central de nossa argumentação. O objetivo deste trabalho é promover a discussão sobre o acesso à informação e ao conhecimento produzido na universidade, além de difundir os conceitos relacionados aos repositórios de dados, quanto ao Movimento de Acesso Aberto e a Ciência Aberta. Esses movimentos são protagonistas de uma forma de pensar a informação em um mundo globalizado e capitalista neoliberal. A força motriz dessa forma de tratamento da informação são as Tecnologias Digitais de Informação e Comunicação. Com o uso em larga escala dos recursos computacionais e com a popularização da Internet, a sociedade pode intensificar o registro da maioria dos documentos produzidos pelas institucionais de educação e pesquisa. Programas e sistemas computacionais foram desenvolvidos especificamente para tornar o acesso à informação livre de barreiras. Questões como tradição e memória serão beneficiadas com esta nova tendência e todo um sistema complexo de informação, trabalho, profissões e instituições aumentarão a capacidade de uso e reuso da informação registrada e preservada. Desse modo, as universidades brasileiras poderão se beneficiar dessa tendência e criar seus repositórios de dados científicos e assim preservar a memória científica e institucional em prol da ciência e da sociedade em geral.

“To stop voting is to vote for the enemy”: Catholic Church and press in building voters in Rio Grande do Sul (1945-1950)
Authors: Angeli Douglas Souza
Published: November 2020

: In order to understand the mobilization aimed at building voters in the initial period of the democratic experience, that is, building an interest in the act of voting at the time of the return of elections, the creation of national political parties and the significant expansion of the registered voter, this article analyzes the role of specific agents in this mobilization work: the Catholic Church, the Catholic Electoral League and the Catholic press. The study has Rio Grande do Sul as its spatial cutout and the newspapers Correio Rio-Grandense and Jornal do Dia, as well as Unitas - bulletin of the ecclesiastical province of Rio Grande do Sul. For such agents, in this moment of expanding electoral participation, how should the Catholic voter behave? What meanings were attributed to the act of voting? The construction of the Catholic voter is driven by a markedly anti-communist speech, articulated to the Church's positioning strategies before the State and to the practices of mobilization of the clergy and the Catholic Electoral League with a view to enlistment and voting.
