Proportionality of Restrictions on Socio-Economic Rights and Freedoms of Citizens
Authors: Uvarov A. A.
Published: April 2022

The area of socio-economic relations is the most popular in the life of citizens. Thus, a person perceives every restriction of his socio-economic rights in a more sensitive way. The restriction itself, in the positive meaning of this term, is a consequence of the collision of different principles and values when it is necessary to solve any state tasks and issues of public administration. Restrictions exist both in law enforcement and law-making, while the problems of restrictions in lawmaking have become especially relevant in connection with the activities of the Constitutional Court of the Russian Federation and the European Court of Human Rights. Proportionality of restrictions on human rights and freedoms forms the most serious problem. The paper analyzes the practice of the Constitutional Court in assessing the proportionality of legislative restrictions on socio-economic rights and freedoms of citizens. Attention is drawn to the fact that not all aspects of these restrictions can be assessed by the Constitutional Court in terms of their compliance with the Constitution of the Russian Federation. Thus, as a legislative discretion, the court recognizes the establishment of quantitative criteria or economic indicators that are not correlated with the relevant constitutional provisions. In this case, the Constitutional Court and the European Court of Human Rights can only offer abstract tools that is advisable for the legislator to be guided in its lawmaking. The author concludes that the socio-economic sphere regulation should be based on the people’s trust in professional managers, which does not prevent them from exercising control over them and changing their team in case of insufficient realization of their socio-economic interests.
The Category of an Interest in Tax Law
Authors: Shchekin D. M.
Published: April 2022

The author was faced with the task of studying the category of an interest in tax law, identifying signs of this phenomenon and finding forms of its interaction with tax law. The paper defines the concept of an interest as a conscious need with motivation for actions aimed at achieving the goal. From these positions, the approaches of other authors to the category of interest are analyzed, the forms of interaction between tax law and an interest are indicated: firstly, an interest can serve as a socio-legal basis for subjective law; secondly, legitimate interests may exist in tax law as a special technique of legal technique; thirdly, interests may not yet be recognized by a legislator, but they can be in need of such recognition. In the latter case, the task of the doctrine of tax law is to identify and propose legal forms of securing interests in legislation. Through the prism of these forms of interaction of tax law and interests, the author analyzes the norms of legislation on taxes and fees, in which the category of interest appears.
Methodological Foundation of Civil Law Regulation of Remote Investment Transactions
Authors: Matytsin D. E.
Published: April 2022

The author examines the risk of property losses for participants in remote investment transactions as a methodological basis for their civil law regulation. The author describes the risks inherent both to the recipients of investments and private investors when making these transactions in the info. The conclusion is substantiated that external and internal risks are characteristic of both credit institutions and other economic entities. If such a legal entity finds itself in the position of a recipient of investments, these risks in their actual implementation will prevent this entity from fulfilling its obligation to the investor in a timely and full manner. According to the author, all possible negative events eventually crystallize into a single risk that opposes the agreements with the investor that took place within the framework of the transaction — the risk of non-payment of the recipient of the investment. In this regard, the author presumes the property losses of the participants in the transaction and the avalanche-like reaction of conflict tension spreading along the chain of non-payments that can involve hundreds of subjects and destabilize not only the investment transactions, but also the transactions made under civil law as a whole. The methodology of civil law regulation of remote investment transactions should be based on the inevitability of the risk of property losses of participants in these transactions. The author of the paper makes proposals concerning formation and functioning of preventive legal mechanisms that minimize the negative impact of this risk.
Etiotropic therapy of the new coronavirus infection: expectations and realities at the beginning of 2022. Part 1
Authors: Kuznetsova Olga Yu.
Published: April 2022

The review includes an analysis of the latest literature data on the etiotropic therapy of a new coronavirus infection. The search for an effective antiviral treatment for SARS-CoV-2 infection is ongoing. Often, the urgent need for an antiviral drug was a pretext for testing drugs without pharmacological justification, bypassing the generally accepted procedure for conducting multi-stage clinical trials. In this regard, many clinical trials involving thousands of patients did not demonstrate the high efficacy and safety of drugs that were chosen as etiotropic therapy. In this review, we focused on the efficacy and safety of those drugs that have been studied in sufficient detail, which are reflected in international publications, and are also included in Russian guidelines for use on an outpatient practice: favipiravir and molnupiravir. The mechanism of action of antiviral drugs, their effectiveness and possible side effects were studied in clinical trials, the results of which are in the open press, which made it possible to analyze these drugs in terms of the appropriateness of their use in real clinical practice.
A Multifactorial Model of Risk Factors for Non-Contact Musculoskeletal Injury in Collegiate Swimmers
Authors:   , Pollen Travis R. , Silfies Sheri P
Published: April 2022

Swimmers are known for high training loads and overuse injuries. Due to a limited number of prospective studies, especially on college swimmers, the risk factors for injury remain uncertain. The overall objective of this dissertation was to determine the risk factors that were most strongly associated with non-contact musculoskeletal injury in college swimmers. I hypothesized that previous injury, swimming technique, perceived susceptibility to injury, movement competency, and training load would all be associated with injury. I also hypothesized that multiple risk factors would be more strongly associated with injury than any one alone. Thirty-seven Division III college swimmers participated in a prospective cohort study. In the preseason, they completed questionnaires on previous injuries and perceived susceptibility. At the beginning of the season, they completed the Movement System Screening Tool and Freestyle Swimming Technique Assessment. During the season, the student-athletes and swim coach reported their workloads (kilometers swum) and injuries. Univariate and multiple logistic regressions were used to assess the associations between risk factors and injury. Eleven participants sustained an injury. Previous injury (OR = 8.89, 95% CI: 1.78, 44.48) and a cross-over hand position during the entry phase of the freestyle stroke (OR = 8.50, 95% CI: 1.50, 48.05) increased odds of injury. Together, previous injury and hand position at entry estimated model fit at 42.8%, which exceeded the model fit for either risk factor alone by over 14%. After adjusting for previous injury, higher perceived percentage chance of injury decreased injury odds (adjusted OR = 0.11, 95% CI: 0.02, 0.82). Poor scores on the Movement System Screening Tool were not associated with injury (OR = 1.06, 95% CI: 0.96, 1.16). Nor were the number of kilometers swum over the entire season (OR = 1.00, 95% CI: 0.99, 1.01). However, the odds of injury were higher during weeks in which workloads exceeded 37.2 km/week (27.1, 95% CI: 8.2, 89.8) compared to all other weeks. Similarly, compared to all other weeks, injury odds were higher for weeks in which the ratio of the most recent week of training to the most recent four weeks of training (i.e. the acute:chronic workload ratio) exceeded 1.56 (OR = 25.1, 95% CI: 7.7, 81.4). In summary, previous injury, a cross-over hand entry position in freestyle, and low perceived percentage chance of injury all predisposed college swimmers to injury. While college swimmers tolerated high workloads spread throughout the season, injuries were more likely to occur during high-workload weeks than all other weeks.

Published: April 2022

A família é considerada importante na promoção de um desenvolvimento físico, cognitivo e socioemocional adequado. Este estudo pretendeu analisar as associações entre as dimensões da parentalidade positiva, a coparentalidade e o desenvolvimento e socioemocional de crianças entre os 12 e os 36 meses. Para a recolha de dados, utilizou-se um questionário de dados sociodemográficos, a Escala de Parentalidade Positiva, a Escala de Coparentalidade e a Escala de Desenvolvimento Socioemocional, preenchidos pelos pais em suporte de papel. Participaram 347 crianças (50.3% raparigas), com idades entre os 10 e os 35 meses. As mães destas crianças tinham, em média, 34.76 (DP = 4.79) anos e mais de metade terminou o ensino superior (62.1%). A figura paterna tinha, em média, 36.79 (DP = 4.95) anos e 48.3% terminou o ensino superior. Os resultados mostram a existência de correlações fracas e positivas entre o desenvolvimento socioemocional e as dimensões da parentalidade positiva. Além disso, existe uma relação fraca, negativa e estatisticamente significativa entre o desenvolvimento cognitivo e uma das dimensões da parentalidade positiva. As dimensões da coparentalidade não apresentam correlações estatisticamente significativas com o desenvolvimento socioemocional nem com o desenvolvimento cognitivo. Na análise de regressão multivariada, verificou-se que o desenvolvimento emocional está associado com a idade da criança e o envolvimento familiar.

Introduction Custom-made acetabular componenents demonstrate a higher clinical efficiency in revision hip arthroplasty for 3A and 3B uncontained acetabular defects and pelvic discontinuity in comparison with serial implants. However, the cost of customized implants still outweighs the cost of serial implants. Accordingly, the level of economic feasibility of using different implants for various defects of the acetabulum seems to be interesting to investigate. Purpose To analyze the economic efficiency of using customized acetabular implants for 3A and 3B uncontained acetabular defects and pelvic discontinuity in comparison with serial implants. Materials and methods To assess the economic efficiency, the Markov model was applied. The model was built on the basis of 4-year survival data for aseptic loosening, infection, and dislocation in 133 cases of revision hip arthroplasty. Results According to the results of modeling, over a 5-year cycle, customized implants showed a reduction in costs by 11.7 % and an increase in the quality of life of patients by 0.2 QALY in the group of patients with 3A uncontained defects in comparison with serial implants. In patients with 3B uncontained defects and pelvic discontinuity, custom-made implants also showed a reduction in costs by 20.8 % and 41.1 %, and QALY values were also higher in the groups of patients who had custom-made implants at 0.6 and 1.4 QALY units, respectively. Conclusion The use of custom-made implants is a more cost-effective strategy in comparison with the implantation of serial acetabular components.
El sistema electoral de segundo grado de las diputaciones provinciales
Authors: Garrido López Carlos
Published: April 2022

En el sistema electoral de las diputaciones provinciales, son los concejales de cada partido político, coalición, federación o agrupación de electores quienes eligen, entre sí, en cada circunscripción, a los diputados provinciales que les corresponden en función de los votos obtenidos en las elecciones municipales. Debido a tan singular sistema, la elección de los diputados se desarrolla necesariamente en una fase posterior a la constitución de los ayuntamientos, una vez que la junta electoral provincial ha distribuido los escaños de la diputación entre las diversas circunscripciones en que se divide la provincia y después de que las juntas electorales de zona repartan los puestos de diputado provincial que corresponden a los partidos, coaliciones, federaciones y agrupaciones más votados en cada circunscripción. En este trabajo expondré las razones que llevaron a configurar este sistema electoral y analizaré cada una de sus fases, así como algunos de sus elementos más característicos e insólitos, como la utilización de los partidos judiciales como circunscripción electoral, el protagonismo atribuido a los partidos políticos y la existencia de tantos colegios electorales de segundo grado como candidaturas logran escaños en cada circunscripción.
Consulta anticorrupción de Colombia de 2018: ¿Buena o mala democracia participativa?
Authors: Ramírez Nárdiz Alfredo
Published: April 2022

El 26 de agosto de 2018 se celebró en Colombia la Consulta Popular Anticorrupción. No tuvo efectos jurídicos directos al no alcanzar la participación mínima exigida, pero los efectos indirectos y las características de la consulta merecen estudio y reflexión. Los promotores defendieron que contribuyó a visibilizar la corrupción como un problema capital de la sociedad colombiana. Los detractores la consideraron un recurso de promoción política personal de los primeros. Cabe preguntarse si la consulta fue un instrumento participativo que mejoró la vida política colombiana o una perversión de la democracia participativa que la empeoró. Este texto expone la regulación y práctica de la consulta popular en Colombia, analiza la consulta de 2018, desarrolla una serie de elementos que se proponen para determinar qué es y qué no es buena democracia participativa y, desde ellos, estudia la naturaleza de la consulta. Se concluye que la consulta tuvo aspectos positivos, pero no fue una buena práctica participativa.
La disciplina de partido y los derechos fundamentales de los afiliados: Un recorrido jurisprudencial
Authors: González Moro Alicia
Published: April 2022

La mayoría de los conflictos que se producen en el interior de los partidos políticos derivan del difícil equilibrio entre la garantía del pluralismo y el mantenimiento de la cohesión interna. El presente trabajo expone la evolución de la jurisprudencia constitucional sobre esta cuestión: una doctrina que, inicialmente, partía de una posición favorable al derecho de autoorganización de los partidos, pero que ha avanzado hacia una mejor protección de los derechos fundamentales de los afiliados. A partir del análisis de la reciente STS 412/2020, se comprueba cómo la aplicación de esta doctrina permite corregir los excesos en el ejercicio de la potestad disciplinaria; ahora bien, es posible limitar aún más el margen de autonomía de los partidos para elevar el estándar de protección jurídica del afiliado y conseguir organizaciones más plurales y participativas en consonancia con el mandato constitucional de estructura interna y funcionamiento democráticos.

Geopolitics of Rohingya Refugee Crisis and Regional Security
Authors: Hossain A N M Zakir
Published: April 2022

Millions of Rohingya were forced to flee their home and became effectively stateless due to countless violations and vulnerabilities in Myanmar. Their future has become jeopardized with a profusion of uncertainties; however, like other displaced people, Rohingya also got media attention when disaster and conflicts forced them to flee. This study aims to explore and classify the determinant factors that push the Myanmar government to force the Rohingya to flee. It also explores the indicators that moulded the South and Southeast Asian geopolitics. The research intends to categorize the conditions that triggered the Rohingya crisis, while the regional geopolitics capture Rohingya as a proxy to intensify the regional proximity. The study found that Rohingya seek opportunities for rights while financial and institutional inability bewildering to respond to their needs and increase the proximity of evasive commitments for the next move by the national and regional government. It is also evident that the plight of these people is precarious and vulnerable, where the provision of legal protection is rare. The great powers of this area intentionally avoid the issue and indirectly influence the countries to increase the regional security tension by supporting armament. This issue dramatically influences the domestic and regional politics of South and Southeast Asian countries and redefines their mutual relationships with the great powers. The study provides a glimpse of the polarization and politicization of the Rohingya minority in the regional security and geopolitical context.

Authors: Mouafo Donald , Biaou Ulrich
Published: April 2022

Recent progress in computer vision applied to facial analysis has led to state-of-the-art face detection and facial feature extraction models. A cautious implementation of these models into face recognition pipelines can enable achieving superior performances and popularized daily applications of face recognition in a variety of domains. However, modern face recognition system is a multi-steps process including face detection, feature extraction and classification model. Developing a high-performance face recognition application generalizing on local data set remains challenging. In this paper, we present Deep learning based face recognition system employing MTCNN for face detection and FaceNet for feature extraction. We compare KNN and SVM classification models trained on the facial features extracted from prepared labeled faces. Both models demonstrated almost 100% accuracy on static test faces. Moreover, as face pose get more pronounced, far above 30°, both SVM and KNN models demonstrate efficient recognition rate of 95.95% and 96.67% respectively. Real-time evaluation shows less than 1% deviation from the static performances with both classifiers on less 30° tilted images.

Published: April 2022

In this article, high temperature oxidation behaviour of plasma sprayed carbides and oxides reinforced composite CoCrAlY coatings were investigated at 700°C. CoCrAlY was reinforced with Al2O3+YSZ, CeO2, WC-Co, Cr3C2-NiCr individually to produce four different coatings. SEM, EDS and XRD are used to analyze the oxide scales formed during oxidation process on the coatings surface. From the results it is found that, all these coatings exhibited parabolic weight gain nature, indicating presence of protective oxide scale on coating surface, whereas changes in total weight gain is observed. CoCrAlY+Al2O3+YSZ coatings exhibited higher oxidation resistance than other coatings. The distribution of thermodynamically stable á- Al2O3 in the coating is shown slow-scale growth kinetics during the oxidation.
Oxidation resistance by HVOF coating of MDN-121 on turbine material
Authors: D Prabhakaran , N Jegadeeswaran
Published: April 2022

Surface corrosion, such as oxidation, occurs in gas turbines at high-temperature locations such as turbine edges. Because of the absconds, the turbines became less compelling and loud. The focus of the exhibit is on a high speed oxy-fuel coating of MDN-121 unusual steel using a blended mix of cermets powder consisting of 25% Cr3C3NiCr+75% NiCrAlY. In a hot environment at 750oC, oxidation tests were performed on coated and uncoated MDN-121. Cycles of 1 hour warming and 20 minutes cooling were used in thermogravimetric testing. Weight estimation was done after each cycle. The tests were characterized using XRD and SEM/EDS after 50 cycles were completed. It was observed that the coated test is more oxidation safer than the uncoated test. Surface morphology from SEM/EDS shows that the surface is wealthy in oxides. Gravimetric examination demonstrated that the weight picks up of the test takes after a illustrative relationship with time. The rate steady for the coated test was much for the coated sample was much lesser compared to the uncoated sample.
A comparative study of biodiesel production by microwave assisted and conventional transesterification methods
Authors: Y H Basavarajappa , H Taranath , S.P Darshan , R Vinod , Banapurmath R
Published: April 2022

Nowaday’s use of biofuels for both power generation and automobiles is more relevant because of the need for energy security, environmental concerns, foreign exchange savings and socio-economic issues. Non-edible oils are considered as second generation alternative fuels and use of these oils avoids conflict between food and energy security. Therefore various locally available vegetable oils of edible and nonedible nature were selected for their biodiesel production. Subsequent characterization of these biodiesels was carried out to ensure their suitability as alternative fuels in diesel engines. Subsequently characterization of both raw vegetable oils and their respective biodiesels was done according to ASTM standards. The experimental investigation also suggests that the fuel processing with conventional transesterification method is a laborious and time consuming one. On the other hand microwave assisted transesterification (MATM) is found to be better in terms of shorter reaction time, lower consumption of power and resources compared to conventional transesterification process. MATM method reduces the reaction time drastically for both edible and non-edible oils. For edible oils the reaction time is found to be 1 minute while for nonedible oils it varies from 3 to 6 minutes. The biodiesel production from pressure reactor uses same resources required by the conventional transesterification method [CTM], but it is conducted in a closed vessel. This feature enhances the chemical kinetics, thereby reducing the reaction time up to 66% compared to conventional method.

Published: April 2022

In the present work, bead-on -plate welds were carried out on 304L austenitic stainless steel using synergic MIG process. In this present investigation 304L having 1.2 mm diameter was used as an electrode with direct current electrode positive polarity. Argon and CO2 was employed for shielding purposes. The fusion zone is defined by a few geometrical characteristics, such as bead width, bead height, and penetration depth. A number of factors influence the configuration of the fusion zone, including gas flow rate, voltage, travel speed, and wire feed rate. Micro hardness measurements were done over the weld bead base material to better understand the Knoop micro hardness.

The advanced gas turbine is designed to operate at higher temperature to increase thermal efficiency. Since the gas temperature exceed the allowable material temperature, so cooling techniques of turbine components are more important. Effusion film cooling is an external and highly sophisticated cooling technology, which protects the liner by injecting the secondary cooler fluid at particular locations over the liner surface exposed to the higher gas temperatures. The injected fluid forms as a thin layer (film) on the liner surface and protects the liner surface from higher gas temperatures. In elliptical geometry of holes in plate for effusion cooling is studied for the samples made of adiabatic and conductivity material. To increase the life of combustion chamber it is essential to know the amount of cooling air to be used for cooling of the liner. For effusion film cooling, geometry of the hole is one of the key parameters which influences the coolant mass flow rate and it spread over the liner surface thus affecting the cooling effectiveness. The commercially available FloEFD software is used for calculating the surface temperature and effusion cooling effectiveness distribution throughout the sample plate and result values are in good agreement and this has given confidence to usage of the commercial software FloEFD for predicting the film effectiveness. After result validation finally concluded that span wise elliptical hole (Config-2) have more effectiveness than circular holes.

Many industries such as oil, gas, aerospace, and automotive, use axisymmetric adhesively bonded single lap joints. Different materials are frequently mated using axisymmetric lap joints. When composite adherents delaminate, the stress circulation inside the adhesive layer significantly influenced. As a result, the importance of considering adhesive layer stresses in the presence of considerable delamination is investigated in this paper. To understand stress analysis and examine adhesive bond strength at static loading conditions, the model created using finite element analysis with cohesive zone modelling. A complete parametric study carried using simple finite element code in ABAQUS, the axisymmetric single lap joins adhesively bonded joints prepared with different material adherents. Analysis carried on the influence of numerous factors such as the distribution stress inside the adhesive joints. In this connection, mating of carbon reinforced polymer composite to titanium alloy adherends discussed thoroughly. The results show that depending on the position of the delamination, the presence of a throughout-the-thickness delamination affects the structural response of both single lap and axisymmetric adhesively bonded joints by varying overlap length. The presence of a delamination reduced adhesive peel and shear stresses significantly in both joint configurations.

Because of the good shape memory effect and superelasticity, copper-based shape memory alloys (SMAs) with aluminum and beryllium as binary and ternary elements are widely used in many applications (Cu-Al-Be SMAs). However, they are prone to corrosion in atmospheric conditions. This alloy is susceptible to corrosion due to hydrogen. This affects the characterization of the SMAs by absorbing the hydrogen and results in hydrogen embrittlement, makes changes in SME and SE effect. The process of hydrogen absorption was carried out under electrolytic charging under constant current density and the charged specimens were aged in the air at room temperature. The results show the decrement in SME from 99.8 % to 62%, and the tensile test revealed an increment in the transformation stress level from 200MPa- 290MPa in the case of the charged specimen.

The aim of this study was to evaluate the Ecological Footprint (EF) for Environmental Sustainability in Ijebu Ode. The study adopted a descriptive cross-sectional study design and the objectives were, to assess the average EF of Ijebu Ode. Both primary and secondary data were employed, and the primary data for this study was collected from four hundred (400) systemically sampled households through structured questionnaires, and analysed descriptively using the Statistical Package for Social Sciences (version 20.0). The findings revealed the average ecological footprint of the Ijebu Ode to be 0.3gha per capita, with the footprint of water as the highest contributor to the EF, with 0.9gha (86.5%) of the total footprint. Thus, the study concluded that, the average EF of Ijebu Ode is 0.3 gha and therefore sustainable. However, it was recommended that, sustainable consumption must be encouraged, implemented and demonstrated to sustain the current EF of Ijebu Ode and public campaigns should be encouraged and implemented adequately in light of increasing awareness of the adverse environmental impacts of unsustainable consumption.

Bu makale, İstanbul’daki haftalık pazarları ve üretici pazarlarını, gıdanın sosyal, mekânsal ve ekolojik gömülülüğü bağlamında değerlendirmektedir. Makale, öncelikle, gömülülük yazınının ağırlıklı olarak Küresel Kuzey'deki vakalara odaklandığını ve farklı gıda aktörlerinin (toptancılar, satıcılar, çiftçiler, çiftçi-satıcılar) ve üretim uygulamalarının (yerel vs. alternatif (sertifikalı organik vs. sertifikasız organik vs. topluluk destekli sertifikalı vs. 'doğal') vs. konvansiyonel) sıklıkla bir arada bulunabileceği Küresel Güney örneklerini nispeten görmezden geldiğini savunmaktadır. Ardından, İstanbul'un pazarlarında ve yerellik hareketiyle ilişkili üretici pazarlarında yapılan katılımcı gözlem ve görüşme verilerini kullanarak, her iki alanda da gıdanın yeniden sosyalleştirildiğini ve yeniden mekânsallaştırıldığını ortaya koymaktadır. Bununla birlikte, iki alandaki sosyalleştirme ve mekânsallaştırma arasında yapısal olarak farklılıklar vardır: Üretici pazarlarında tüketiciler ve üreticiler arasında önemli sosyo-ekonomik farklılıklar olsa bile, üretici pazarları, ekoloji bilinci yüksek gıda vatandaşlarından oluşan bir topluluk oluşturmayı amaçlarken, pazarlarda mahalle cemaatinin korunması vurgulanmaktadır. Ancak kimlerin bu mahalle cemaatine dahil olduğu mahalleye ve pazara özgüdür. Mesela, şehrin çeperlerindeki pazarlarda satıcılar, çiftçi-satıcılar ve tüketiciler bu cemaatin bir parçası olabilirken; merkezi konumdaki pazarlarda, pazarcılar dışlanır ve pazar dışında var olan mahalle cemaati yeniden üretilir. Kısacası, pazarlar ve üretici pazarları arasında gıdanın sosyal, mekânsal ve ekolojik gömülülüğü açısından farklılıklar olduğu gibi, pazarların ve üretici pazarlarının içinde de bulundukları yerlerden mütevellit farklılıklar mevcuttur. Makale, bu farklılıkların özellikle yerellik odaklı gıda hareketi için ne gibi fırsatlar ve sıkıntılar doğurabileceği tartışılarak sonuçlanmaktadır.

Published: April 2022

Antakya (Hatay), etnik ve dinsel anlamda farklı toplulukların bir arada yaşadığı, Türkiye’de sıklıkla ‘hoşgörü kenti’ olarak dile getirilen kozmopolit sınır kentlerinden biridir. Antakya ve çevresinde yaşayan ve kadim bir topluluk olan Arapça ibadet eden Rum Ortodoks Hristiyanlar, Antakya dışına yaşanan göçler ve güncel toplumsal sorunlar nedeniyle nüfusu azalmış bir grup olup kültürel kimlik ve kolektif bellek açısından devamlılığını sürdürme mücadelesi içindedir. Bu çalışma Antakyalı Ortodoks Hristiyanların etno-dinsel kimliklerinin toplumsal inşası ve gündelik yaşamda kültürel belleklerini kadın ve gençler aracılığıyla aktarma biçimlerini ve deneyimledikleri toplumsal sorunları anlamaya ve açıklamaya çalışmaktadır. Derinlemesine görüşme ve katılımcı gözlem gibi etnografik yöntemler kullanılarak gerçekleştirilen bu çalışma iki temel soruya odaklanmaktadır: 1. Günümüzde Antakya’da yaşayan Ortodoks Hristiyanlar etno-dinsel kimliklerini ve kültürlerini nasıl tanımlamakta ve aktarmaktadırlar? 2. Antakyalı Ortodoks Hristiyan cemaatinde, özellikle kadın ve gençler arasında, kültürel belleklerini, anlama ve anlatma biçimleri nelerdir? Teorik anlamda kültürel bellek ve etnik sınırlar yaklaşımları kullanılarak, bu araştırmada Antakyalı Ortodoksların kültürel bellek aktarımı ile hatırlama biçimlerinde kadının yeri ve rolü, belleğin gençler ve çocuklara aktarımı, dinsel ritüeller, isim koyma, miras ve karma evlilikler üzerinden ele alınarak tartışılmıştır. Bu araştırma kapsamında toplam 48 derinlemesine görüşme, dört odak grup görüşmesi ve etnografik çalışma Antakya, Altınözü, Arsuz, İskenderun ve Samandağ ilçelerinde Nisan 2016-Aralık 2021 yılları arasında gerçekleştirilmiştir. Çalışmada Antakyalı Ortodoksların, kadınları ve gençleri modern gündelik hayatta yaşanan değişim ve dönüşüme rağmen kültürel belleğin aktarımında en önemli özneler olarak gördüğü sonucuna ulaşılmıştır.
