The synthesis of complexes based on diethylenetriaminepenta-acetategermanate(IV) acid and a number of exo-ligands was carried out. Their composition, thermal stability, method of coordination of diethylenetriaminepentaacetic acid (H5Dtpa) and protonation of exo-ligands (isoniazid Ind, diphenylguanidine Dphg, piracetam Pam, imidazole Im, cytosine Ctz, 1,10-phenanthroline Phen, 2,2´-bipyridine Bipy), were established. The structural scheme and molecular formula of the obtained compounds were proposed (HL)[Ge(OH)(HDtpa)]·nH2O, де L = Ind, n = 0 (1), Dphg, n = 8 (2), Pam, n = 4 (3), Im, n = 2 (4), Ctz, n = 2 (5), Phen, n = 5 (6), Bipy, n = 4 (7).
Based on the elemental analysis of the synthesis products 1–7, it was determined that they exhibit a molar ratio of Ge:N = 1:6 (1, 2, 5), Ge:N = 1:5 (3, 4, 6, 7), therefore, Ge:Dtpa:Ind (Dphg, Pam, Im, Ctz, Phen, Bipy) = 1:1:1. The thermal decomposition of complexes 2–7 begins with an endothermic effect in the temperature range of 80–180 °C, during which a certain amount of crystallization water molecules is removed. The relatively high temperature of its removal is due to the formation of a broad system of intermolecular and intramolecular hydrogen bonds, which is characteristic of various metal complexonates. Thus, in the new compounds, the structure of the octahedral polyhedron of Germanium remains the same as in the original complex acid: the Ge atom is coordinated by two Nitrogen atoms and three Oxygen atoms of three Dtpa acetate groups. The coordination number of Germanium is complemented to 6 by the hydroxo-ligand.
All carboxyl groups of the ligand are deprotonated, as evidenced by the presence of bands νas(COO⁻) at 1630–1690 cm⁻¹ and νs(COO⁻) at 1380–1420 cm⁻¹. The presence of Ge-N and Ge-O bonds in the synthesized complexes is confirmed by the bands of valence vibrations of these bonds in the range of 640–650 cm⁻¹ and 590–620 cm⁻¹, respectively. Particularly noteworthy is the band of deformation vibrations of the Ge-O-N group at 810–820 cm⁻¹. In complexes 1–7, a splitting of bands in the 3000 cm⁻¹ region (valence vibrations of the C-H bond) is observed, indicating that all nitrogen atoms in their molecules are coordinated or protonated.
The obtained compounds are of interest as promising agents for biomedical applications.

Published: March 2024

Much research attention has been paid to amino acids as an alternative to amino alcohols for capture of sulfur dioxide. Taurine (Tau) occupies a special place among amino acids. This study was stimulated by the limited literature data on the nature of the interaction of SO2 with Tau salts aqueous solutions, the composition and relative stability of the corresponding reaction products.
Chrono-pH-, chrono-redox- and chrono-conductometric studies of SO2 chemisorption with potassium taurate (TauK) and monoethanolammonium (TauMEA) aqueous 0.1 M solutions were carried out in the temperature range 293–313 K to study these processes.
The maxima on the differential pH-metric titration curves positions coincide with the positions of the jumps on the integral and maxima on the redox-metric titration differential curves, as well as with breaks on the conductometric curves position. Δk negative values indicate the formation of weakly dissociated particles or less mobile ions in the solutions under study that is confirmed by the data of mathematical calculations.
Using a mathematical model that takes into account the law of mass action, material balance and electrical neutrality principle, SO2 – TauK – H2O solutions ion-molecular composition and ionic strength were calculated. With an increase in the chemisotption SO2 amount, the taurate anions concentration decreases due to the hydrolytic transformation into zwitter ions +NH3CH2CH2SO2O - and the sequential transformation of hydrotaurate-sulfite (4:1 and 2:1; I and II), taurate-sulfite (2:1; III), hydrotaurate-hydrosulfite (2:1; IV) and taurate-hydrosulfite (1:1; V) associates. The concentration and thermodynamic constants for the formation ionic associates I–V were calculated.
TauK input into impregnated fibrous chemisorbents (IFCS) composition obtained by impregnating viscose fibers with monoethanolamine aqueous 0.25 M solutions (IFCS-0.25MEA) leads to a synergistic increase in quantity of adsorbed SO2. IFCS-0.25MEA-TauK are long-acting sulfur dioxide chemisorbents, and TauK itself serves as a promoter-modifier towards IFCS-0.25MEA preventing the MEA removal from IFCS surface by the GPS flow due to the ionic associates formation and promoting deeper HOCH2CH2NH2 «response».

Published: March 2024

Chinese herbal medicine (CHM) have a long history, a wide variety, and similar shapes, which lead to the difficulty and low efficiency of traditional CHM identification methods (mainly including original identification, morphological identification, microscopic identification, and physical and chemical identification). In view of the above problems, this paper proposes an improved method based on the traditional convolutional neural network VGG. First of all, this paper is no longer limited to the Conv-Batch Normalization (BN)-Max Pooling network structure model, but uses three (Conv-BN, Conv-Max Pooling and Conv-BN-Max Pooling) interlaced network structures. Second, we use GAP to connect the convolutional and fully connected layers (FC). The experimental results show that compared with the Conv-BN-Max Pooling network structure, using the above improved network structure can improve the recognition accuracy rate by 3.3% (Epoch 100), and finally achieve a correct recognition rate of 97.86% for 12 traditional Chinese medicine images, which proves that the proposed improved method has certain advantages compared with other network structures, and explores new ideas for the modern identification of Chinese medicinal materials.

Published: March 2024

Artificial Intelligence through advanced algorithms, such as deep learning, has recently been applied in medical imaging, representing an emerging area in the classification of medical pathologies. Deep learning has been widely applied in medical imaging to help automate and improve medical image analysis. Medical imaging techniques such as MRIs, CT scans, and X-rays produce large amounts of data that can be difficult for human experts to accurately interpret and analyze. Deep learning algorithms can be trained to recognize patterns in medical images, identify abnormal features, and make predictions about patient outcomes. The present research work exposes an automatic classification model to detect brain tumors in brain magnetic resonance images (MRI). The data set is found in the Kaggle repository, which consists of 253 MRI images: 155 with brain tumors and 98 without. The proposed model can classify brain tumor MRI images with 91% accuracy. Therefore, the model represents an auxiliary tool to existing conventional methods for the diagnosis of brain tumors.

Development of correction coefficients for cable cross-sections selection in polymeric cable channel
Authors: Shepelev Alexander O. , Osipov Dmitry S. , Tkachenko Vsevolod A.
Published: March 2024

Relevance. The need to develop correction coefficients for selecting cable sections when laying in the polymeric cable channel in the Russian Federation. Currently, there are no recommendations fixed by the state standards for laying cable power lines in polymer pipes. Aim. To develop correction factors for laying cable power lines in the polymer cable channel. Objects. Cable transmission lines laid underground in polymer pipes. Methods. Numerical simulation of combined frequency-stationary method; determination of correction factors based on interpolation of model results; evaluation and analysis of comparison of cables in corrugated and smooth polymer pipes. Results. Calculations of the long-term current load for cables laid in the polymeric cable channel showed the effectiveness of this method of laying cable lines. The use of pipes with smooth walls makes it much more efficient to remove heat from cables into the environment (compared to a corrugated pipe), which allows you to increase the capacity of the same cable by about 25%, depending on the number of pipes laid nearby. Based on the results of the simulation of the thermal mode of corrugated and smooth polymer pipes, it can be concluded that corrugated pipe significantly complicates heat removal from the cable system to the environment (soil). This is due to the presence of air gaps in the ribbed structure of the corrugated pipe. The gaps filled with air act as a heat-insulating layer, unlike a smooth pipe in which this gap is absent. The developed coefficients will take into account the influence of the location of cables on their allowable current already at the design stage, which will reduce the cost of power transmission losses due to the wrong cable cross-section and high temperature.

Authors: Singh Shivani , . Sulekha , Kumar Gulshan , Das Arup Kumar
Published: March 2024

Background: Ultrasonography is a second most commonly used diagnostic imaging technique in veterinary practice after radiography. The ultrasonographic examination of clinically healthy animals provides relevant information about anatomical location, echo texture, size and shape of organs. In the present study, the echo-structural pattern of urinary system of adult female goats were evaluated to find the normal structural pattern of various constituents of urinary system. Methods: B-mode ultrasonographic study of urinary system was performed in 20 healthy adult female Jamunapari goats. Mean±S.E. values of body weight and age of selected animals were 27.49±0.79 kg and 2.77±0.10 years, respectively. All twenty animals were subjected to sonographic examination after clipping the hairs from desired sites to scan the various organs of urinary system in standing position under physical restraint without using any anesthetic agent. The values of various clinico-physiological parameters including rectal temperature, heart rate, respiration rate, colour of mucous membranes were recorded to examine the health status prior to sonography. The left and right kidneys were scanned from right dorsal flank by paravertebral approach using a transcutaneous micro-convex probe at 5 MHz and a convex probe at 2.8-6 MHz frequency. A dual frequency (5-9 MHz) micro-curved array cavity probe was used to scan bladder and urethra per rectally. The renal parenchyma in healthy goats was distinctly divided into hypoechoic outer cortex and anechoic inner medulla. The hyperechoic renal sinus complex was present in center of the kidney and renal pelvis was anechoic. The renal capsule was seen as hyperechoic fine line surrounding the renal parenchyma. Pulsed wave renal color doppler ultrasound was performed in 3 healthy goats with the aim to generate reference images of renal vasculature. Result: The Mean±SE values of renal length, renal height, horizontal diameter of renal sinus, vertical diameter of renal sinus and diameter of renal pelvis for right kidney were 6.11±0.09, 3.26±0.08, 3.01±0.11, 1.32±0.03, 1.05±0.03, respectively while for left kidney these values were 6.02±0.09 and 3.35±0.07, 2.67±0.12, 1.14±0.06, 1.10±0.07 cm. The ureters could not be visualized in any of the goats. The distended bladder was seen as anechoic circular structure surrounded by a smooth echogenic wall with a mean thickness of 1.65±0.06 mm. No significant difference was observed in the measurements of both kidneys except in dimensions of renal sinus. Positive correlation was found between renal size and body weight of goats. It was concluded that ultrasound is an easy, rapid and non-invasive method to evaluate echotexture and morphometry of structures of urinary system.

Published: March 2024

Background: The research work was undertaken to investigate the efficacy of various diagnostic tests by using conventional microscopic examination, rapid Ab detection test and molecular technique, haemato-biochemical changes, Abdominal organs changes using ultrasonography, and therapeutic efficacy of different treatment protocols on Canine Monocytic Ehrlichiosis (CME) infected dogs from in and around Navsari, Gujarat, India. Methods: 69 dogs suspected of ehrlichiosis based on clinical signs and hematological values and then subjected to blood and buffy coat smear examination, rapid Ab detection test and PCR based assay targeting 16S rRNA gene. The pre and post-treatment haematology and biochemical analysis of treatment groups along with all the positive dogs were performed. Further, all the treatment group dogs were subjected to ultrasound for evaluating organ abnormalities. Modified Clinical Sign Grading (MCSG) score for CME-infected dogs was carried out to evaluate therapeutic responses based on minimizing the clinical score. Descriptive statistics along with Student t-test and One-way analysis of variance (ANOVA) followed by DMRT was performed to compare differences between means wherever applicable. Result: CME incidence among the 69 suspected cases was 49.28%. Out of 69 suspected dogs, Ehrlichial inclusions or morulae in the monocytes could be identified in only 4.35% of blood smears and 10.14% of buffy coat smears examined by Giemsa and or Field-stained and 15.94% of dogs were found positive for Ehrlichia genus by PCR. 72.5 per cent of dogs were found positive for antibodies to E. canis, out of 40 dogs. The sensitivity of blood smear examination, buffy coat smear examination, and thrombocytopenia was 10.34%, 24.14% and 89.66%, respectively. The specificity of all the diagnostic tests was 100%. The anemia along with leucopenia, were the most significant hematological alteration recorded while ALP, creatinine, and BUN were elevated and albumin was significantly decreased in CME-infected dogs. Significant improvement of haemato-biochemical parameters towards normalcy in both treatment groups. However, a higher percentage of reduction was observed in the clinical score of imidocarb treated CME affected dogs than in the oxy-doxycycline therapy after 14 days.

Citizens and experts on trust in the institutions and policies of the Russian state
Authors: Merzlikin Nikolay
Published: March 2024

The article is devoted to the sociological analysis of the level of trust of the Russian society to the authorities in the conditions of Russia's special military operation in Ukraine. The events of February 2022 became a turning point not only in the global, but also in the internal Russian socio-political situation, marking the beginning of cardinal transformations in the mood and public position of Russian citizens. Under such conditions, the institution of trust becomes one of the most important priorities in ensuring the sustainability of the Russian statehood. The analysis is based on the comparison of data from expert surveys conducted with the author's participation in 2022-2023 with the results of the all-Russian sociological monitoring "How are you, Russia?" (both studies were conducted by ISPR FCTAS RAS). The assessment of both expert and mass sociological surveys allows us to conclude that the majority of society understands the crucial nature of the special military operation for the future of the country and supports it. Over the two years since the beginning of the special operation, citizens' trust in the president and the institutions of power has grown, the course for the denazification of Ukraine, according to experts, is supported by key actors of civil society (although the categorical attitude to the special operation, whether positive or negative, is gradually being replaced by a neutral one, which may be due to the routinisation of the subject). Based on the analysis of the dynamics of expert assessments and sociological monitoring data, the author concludes that a new social reality has emerged in the country, the distinctive feature of which is the formation of a stable nucleus of social actors that maintain a high level of public trust in the state, but it has not become prevalent and unchanged at the moment.
Health behavior: theoretical and methodical problems of sociological measurement
Authors: Chirkova Anna
Published: March 2024

The article is devoted to a comparative analysis of approaches to the study of health behavior that exist in modern Russian and foreign sociology; identifying theoretical and methodical problems; designation of directions for the development of this issue. The article shows that specific theoretical and methodical problems generated in various approaches can be generalized into two groups. The first correlates with problems of cognitive adequacy of the variables used for analysis. It includes such problems as adapting variables to measure social attitudes or behavior; choosing the optimal way to empirically interpret indicators of health behavior; identifying discrepancies between self-assessments and the results of “objective” measurement. The second group of problems is related to the complexity of the relationships between the components of such behavior, which includes: the mediation of the relationships between the components of health behavior by indicators of a different nature; identification of factors that influence health behavior in different directions, their specificity for various health practices; implementation of conceptual representations in multidimensional data analysis models. The article pays special attention to typological studies as one of the important directions in the development of the problem of sociological measurement of health behavior, which makes it possible to overcome many theoretical and methodical problems. In particular, the advisability of a priori typology of the population being studied is emphasized; testing a number of indicators of health behavior as type-forming attributes; using the experience of conducting typological analysis in subject fields close to the field of health.

In the case of international disputes resolved by means of arbitration, the cross-border effects of the awards are essential for the parties. At first glance, these awards are assimilated to the national court judgements of the state where they were pronounced and are considered foreign court judgements in any other state. Nevertheless, in some cases, the links between the arbitral procedures and the place of pronouncement of the awards are weak or even non-existent, which raises serios doubts over the ability of this specific place to determine the nationality of the arbitral award. The described circumstance is the premise of the present scientific approach, which aims to deepen the analysis of the criteria for determining the nationality of an arbitral award (by a Romanian court), with implications on its cross-border effects, as well as on the procedures that could lead to its dissolution. From a methodological point of view, the research aims, successively, to inventory the applicable legal instruments, to delineate the solutions offered by them, in order to, finally, by overlapping them, provide a comprehensive theory on the determination of the nationality of an arbitral award.

The energy transition is one of the most relevant priorities in the context of the current production and consumption system. Finance, through Sustainable Finance, must start redirecting money flows towards projects with less impact on the environment. Through portfolio construction, this paper conducts an analysis based on Monte Carlo Simulation and Value at Risk. Based on a sample of 40 international banks, distributed by those that invest more in fossil fuels vs. those that invest less, the main objective of this work is to know the financial viability of the different portfolios considering their return and risk. The results show that the banks that are divesting more in fossil fuels have a lower return and a higher risk compared to those banks that continue to invest in fossil fuels. According to the Monte Carlo Simulation, there is also a better performance of those banks that continue to have a strong fossil fuels investment policy. According to these results, it seems that stronger restrictions should be imposed on fossil fuels investment in order for the major banks to become profitable by investing in projects with lower environmental impact. An in-depth analysis of the policy and legal implications of this performance is a line that can be addressed in the future.

Published: March 2024

A robust securities market is the engine of a country's economy. Undoubtedly, the stability and strength of a country's financial intermediaries and secondary market systems determine its overall economic growth. Since 2009, when the secondary market and Egypt’s EGX 30 stock index were established, the Egyptian economy has been on a trajectory of growth. However, Egypt's economy has been facing various economic and financial challenges in recent years because of political instability and social unrest, starting with the 2011 political revolution and the global external shocks such as the Corona pandemic, which negatively impacted its foreign capital inflows from the hard currency. Which made it essential and critical to ask for financial assistance from international institutions and the global financial market to maintain the country's economic wellbeing. That was linked to economic structural reform-backed loan programs and agreements with the IMF and the World Bank. Since then, it is assumed that Egypt’s economy is moving towards more cointegration with the global economy, especially after the IMF-backed loan program and the economic reforms that took place since the end of 2016 with the currency flotation regime in November 2016. Since then, Egypt’s economic stance, stock market, and foreign exchange rate turned out to be more reflective and vulnerable to the external shocks that are taking place. And with the association of the IMF loan program, the financial capital market via foreign capital inflows in the foreign portfolio investments, has played a main role in influencing the currency performance through Egypt’s equity and debt markets, which are directly and indirectly influenced by Egypt’s Central Bank monetary policy decisions. This paper helps to understand the stock, foreign exchange markets in Egypt and the impact of the government’s monetary policy on the financial market. It aims at identifying the determinants of both markets, investigates the relationship between macroeconomic variables on Egypt’s EGX30 all-share stock index and Egypt’s FX rate. The macroeconomic interrelations are examined including Egypt’s lending interest rate and the 91-day Treasury bill (T-bill) rate. By applying the cointegration model and the VECM model to test the short-run and long-run relationships between the noted variables. The findings indicated a long-run relationship between Egypt's stock market index, lending rates, and T-bills over the period from 2010 until 2016, before the currency flotation regime.

Authoritarian leadership is prevalent in the Asian region, and previous research has found a positive correlation between authoritarian leadership and employees' intention to leave their jobs. However, there are employees in the workplace who can adapt to such supervisors. Therefore, we approach this study from the perspective of "fit theory" to explore whether employees with authoritarian family upbringing can match with authoritarian leadership. This study aims to investigate the impact of authoritarian leadership on employees' intention to leave, with supervisor satisfaction as the mediator and employees' authoritarian family upbringing as the moderator. A total of 232 valid questionnaires were collected in this study. The results revealed that the level of authoritarian family upbringing among employees has a moderating effect on the relationship between authoritarian leadership and supervisor satisfaction.

Published: March 2024

The paper discusses the concept of using non-curricular arts to strengthen the social status of engineers by expanding skillset and perception, building bridges, and connections. While there's no definitive answer of how non-curricular arts are used to strengthen the social status of engineers, the study presents some artistic ways of engagement that can impact engineers' social standing by demonstrating creativity and innovation, communication and storytelling, collaboration, and empathy. The study shows that the impact of non-curricular arts on engineers' social status depends on individual engagement, societal context, and how the artistic pursuit is perceived. While not a guaranteed formula, actively engaging in diverse artistic mediums can certainly contribute to a more well-rounded, respected, and connected image of engineers within society. Finally, the paper presents a comprehensive overview of how non-curricular arts can potentially influence the social status of engineers.

Ayrıca, kurumsal sosyal sorumluluk faaliyetlerine yönelik algının güven üzerinde ve sadakat üzerinde anlamlı ve pozitif etkisi olduğu sonucuna da ulaşılmıştır. Demografik değişkenlere göre değerlendirildiğinde, evli ve bekâr tüketiciler arasında sadakat ve satın alma niyetinde anlamlı farklılık görülmektedir. Tartışma –Elde edilen sonuçlar literatür ile uyumludur. Dai ve Reich (2022) yaptıkları çalışmada kurumsal sosyal sorumluluk faaliyetleri ile marka güveni açısından pozitif yönde bir ilişki olduğunu tespit etmiştir. Kurumsal sosyal sorumluluk algısının güven üzerine etkisini inceleyen bir çalışmada, sosyal sorumluluk algısının güven üzerinde pozitif yönde etkili olduğu sonucuna ulaşılmıştır (Karaboğa vd., 2020).

Authors: Kılıç Sultan Nazmiye
Published: March 2024

Amaç –Günümüzde değişmekte olan yaşam koşulları ve grileşen sosyo-demografik yapıyla birlikte orta yaş üstü grubun farklı boyutlardan araştırılması gerekli hale gelmiştir. Bireyin yaşamında önemli dönüm noktalarından biri olan emeklilik olgusunun toplumsal ve ekonomik açılardan farklı katkıları olabilmektedir. Bu doğrultuda, emekli olduktan sonra turizm girişimciliği faaliyetlerinde bulunan bireylerin yaşam öykülerinden yola çıkarak deneyimledikleri süreçlerin anlaşılması; politika oluşturma, alan yazını geliştirme ve sektörel uygulamalara ilişkin konularda katkı sunabilecektir. Araştırmada, emekli olduktan sonra turizm sektöründe girişimde bulunan bireylerin biyografik anlatıları tematik olarak analiz edilerek, turizmde emekli girişimciliği olgusuna ışık tutulması amaçlanmıştır.Yöntem –Araştırmanın amacı kapsamda anahtar kelimeler kullanılarak yapılan web taramasında ulaşılan ve biyografik bilgi sunan Türkçe sayfalar değerlendirmeye alınmıştır. İlgili sayfalarda örnek olayların ve girişimci deneyimlerinin yer alması nedeniyle, bireyin girişimcilik öyküsünü ve biyografisini sunduğu belirlenen 23 biyografik anlatı araştırmaya dâhil edilmiş ve tematik olarak analiz edilmiştir. Kodlama sürecinde MAXQDA programından faydalanılmıştır.Bulgular –Araştırmada girişimcilerin yaşadığı deneyimlerin incelenmesi sonucunda; “motivasyon”, “kolaylaştırıcı-destekleyici unsurlar” ve “turizm girişiminin bireye katkısı” kategorileri altında 18 koda ulaşılmıştır. Biyografik anlatılarda en yoğun vurgulanan unsurların sosyal ve psikolojik faktörler olduğu belirlenmiştir. Emekli bireyleri motive eden faktörlerin ve girişim faaliyetlerinin bireye sunduğu katkılarının belli konularda kesiştiği, emekli bireyleri hayatın içinde tuttuğu ve aktif yaşlanmayı desteklediği görülmüştür. Bireylerin önceki mesleklerinin ve aile desteğinin yeni girişimlere önemli katkılar sağladığı anlaşılmıştır. Kişinin kendisini tanımasının ve ilgi alanlarını fark etmesinin emeklilik sürecinde yeni girişimcilik imkânlarının açılmasına katkı sağladığı belirlenmiştir. Emekli girişimcilerin faaliyetlerinin kültürel zenginliklerin sürdürülmesine destek olduğu ve topluma fayda sunan çıktıların oluştuğu belirlenmiştir. Tartışma –Bulgular değerlendirildiğinde, bireyin emeklilik öncesi ilgi alanlarının, deneyimlerinin ve değerlerinin emeklilik sonrasında girişimcilik faaliyetleri için önem taşıdığı anlaşılmıştır. Bu doğrultuda, sosyal yaşamda bireyi zenginleştirebilecek deneyimlerin hayat boyu öğrenme prensibiyle sunulması, yeni girişimcilik faaliyetlerini teşvik edebilir. Hazırlanacak politikalarda ve yapılacak akademik çalışmalarda emeklilik sonrası yaşama hazırlık için programlar geliştirilmesi ve bireyin sosyal açıdan aktif ve sağlıklı kalmasını destekleyen sosyal programların uygulanması faydalı olabilir

Published: March 2024

Amaç –Örgüt kavramının temellerini oluşturan olgulardan birisi örgütsel hedefler olarak ifade edilmektedir. Örgütsel hedeflerin etkili bir şekilde yerine getirilebilmesi ve örgütün rekabet gücüne ulaşabilmesi için bazı göstergelere ihtiyaç duymaktadır. Örgüt yönetimlerinin kendi çalışanlarını bu doğrultuda yönlendirmeleri için onların fikirlerini dinlemeleri büyük öneme sahiptir. Örgütsel demokrasi, gücün bireyler tarafında bir bütün olarak verildiği ve kararların tartışılarak alındığı bir sistem olarak ifade edilmektedir. Örgütsel sinizm ise çalışanlar tarafından örgüte karşı duyulan negatif duyguları açıklamaktadır. Bu bağlamda bu araştırmada, örgütsel demokrasinin örgütsel sinizme etkisinin belirlenmesi amaçlanmıştır.Yöntem –Nicel araştırma deseninde değerlendirilen bu araştırmada öngörülen araştırma modelinde yer alan örgütsel demokrasi ve örgütsel sinizm değişkenleri, literatürde yaygın olarak kabul edilen boyutlarıyla araştırmaya dâhil edilmiştir. Bağımlı ve bağımsız değişkene ilişkin tanımlayıcı istatistiklerin uygulandığı çalışmada ölçeklere ilişkin doğrulayıcı faktör analizi ve korelasyon analizi uygulanmış daha sonrasında ise yapısal eşitlik modeli kurulmuştur. Araştırma modeli bağlamında Afganista’ın Belh kentinde görev yapan 294 katılımcıdan veriler analiz edilmiş ve yorumlanmıştır.Bulgular –Araştırma sonucunda ulaşılan bulgular örgütsel demokrasinin artmasının çalışanların örgütsel sinizm algısını azalttığını göstermektedir. Ayrıca bu çalışmada ortaya konulan sonuçlardan birisi de örgütsel demokrasi örgütsel sinizmin alt boyutları olan duyuşsal ve bilişsel sinizmin de azaltmasıdır.Tartışma –Bulgular göstermektedir ki örgütsel demokrasi ikliminden beslenen örgütlerde örgütsel sinizm yerini pozitif olgulara bırakma eğiliminde olmaktadır. Ayrıca örgütsel demokrasi iklimi çalışanların örgüt hakkındaki fikirlerini etkilemektedir.

Published: March 2024

Purpose –This paper demonstrates the application of the IDOCRIW-based MABAC and MAIRCA methods in the evaluation of the trade competitiveness of the top fifteen textiles exporters in the world. Design/methodology/approach –The trade competitiveness index was used for assessing the trade competitiveness of exporters in the textile industry. The IDOCRIW method was used to obtain the weight of criteria. The analysis of the trade competitiveness of exporters was carried out using the new multi-criteria methods, namely the MABAC (Multi-Attributive Border Approximation area Comparison) and the MAIRCA (Multi-Atributive Ideal-Real Comparative Analysis). Findings –According to the results obtained by the IDOCRIW method, share in the world market (SWM) and net exports (NEX) were determined as the most and least important criteria with weight values of 0,3297 and 0,0816, respectively. After determining the criteria weight, the alternatives were ranked using the MABAC and MAIRCA methods. The results for both methods indicate that China, Italy, Luxembourg, Belgium, and Spain have the highest trade competitiveness, while Croatia, Ireland, the Republic of Cyprus, Malta, and Mexico have the lowest trade competitiveness in the textile industry. The findings demonstrated that MABAC and MAIRCA provided consistent solutions for ranking the alternatives. Additionally, the consistency and robustness of the results were tested using two different scenarios. The overall results revealed that China and Italy have the best trade competitiveness in the textile industry. Discussion –As expected, China and the European Unioun (EU) countries have the highest trade competitiveness in the world’s textile industry. It can also be stated the textile industry is strategic sector for both the EU countries and China.
Türkiye de Banka Performansı ve Reel Döviz Kurları İlişkisi: ARDL Sınır TestiYaklaşımı (The Relationship between Bank Performance and Real Exchange Rates in Turkey: ARDL Boundary Test Approach)
Authors: Yiğitbaş Şehnaz Bakır
Published: March 2024

Amaç -Bu araştırmanın amacı, reel efektif döviz kurlarının Türk Bankacılık Sektörü’nünperformansı üzerindeki etkisini 2012:03-2023:03 dönemi aylık verilerini kullanarak ekonometrik olarak analiz etmektir. Yöntem -Araştırmada ARDL yöntemi kullanılmıştır. Ekonometrik analizde banka performansını temsil eden Aktif Kârlılığı (ROA) ve Özkaynak Kârlılığı (ROE) olmak üzere iki değişken, döviz kurlarını temsil eden, enflasyon etkilerinden arındırılmış reel efektif döviz kuru (EXR) olmak üzere bir değişken kullanılmıştır. Bankacılık performansı ve döviz kurları arasındaki ilişkinin kısa ve uzun dönem analizleri Pesaran ve Shin (1999) ile Pesaran (2001) tarafından geliştirilen “Sınır Testi” yaklaşımı ile yapılmıştır.Bulgular –Banka performansı ile reel döviz kurları arasında hem uzun dönem hem de kısa dönemde bir eşbütünleşme ilişkisi bulunmaktadır. Türkiye’de reel döviz kurları, incelenen dönem itibariyle banka performansını pozitif yönde etkilemektedir.Tartışma-Döviz kuru oynaklığının bankaların sermaye getirileri üzerindeki etkisi ile ilgili teorik beklenti negatif olması yönündedir. Çalışmada döviz kuru değişkenini temsilen nominal değil, reel döviz kuru değişkeninin kullanılması bu sonucun ortaya çıkmasında etkili olmuştur. İncelen dönem itibariyle döviz kurlarının enflasyon oranlarının altında bir seyir izlediği ve bu nedenle enflasyon etkilerinden arındırılmış reel efektif kurun yıllar itibariyle düştüğü gözlenmiştir. Dolayısıyla, enflasyon oranlarının altında kalan reel döviz kurları, bankaların performansını negatif değil pozitif yönde etkilemiştir.
