Economic, Social, and Political Elites in MENA Political Science
Authors: Shamaileh Ammar
Published: March 2024

Recent Western literature concerning the political determinants of economic and social outcomes has primarily concentrated on regime types and the effectiveness of state institutions. While this literature has been influential among scholars of and in the Middle East and North Africa, there has also been an emphasis in the region on the interests and networks of economic and political elites—the interactions between rulers, elites, and the broader citizenry—to explain divergent policy outcomes. This is largely due to the inability of dominant mainstream institutional and structural theories to explain much of what has been observed in the region, viewing it as exceptional in its authoritarianism and resistance to global trends. In fact, the seeds for a more sophisticated understanding can be found in the literature on the Arab world that emphasizes relational dynamics between political and economic actors. Synthesizing the insights of scholars of the region has the potential to contribute more broadly to global debates on how political factors and conditions within states shape the quality of life experienced by their residents. Such a shift to viewing regimes as networks provides a useful framework for bridging the broader trends in political science with the work emanating from scholarship on the Middle East and North Africa.
Russian Hip Hop and the War in Ukraine
Authors: Vandevert John David
Published: March 2024

In response to the ongoing war between Ukraine and Russia, beginning as early as 2014 but reaching a critical apex in the early parts of 2022, hip hop in Russia has only further cemented its role as a “popular” vehicle for the promotion of cultural activism and sociopolitical critique. Born out of post-Soviet antagonism, imperial hegemony, neoliberal commercialism, and jingoist logic, “Russian” rap is a mouthpiece of contemporary conditions. A tangible vehicle for the rediscovery of post-Soviet optimism and the promise of financial prosperity, rap in Russia both upholds and challenges cultural norms and values. In February 2022, the Russo-Ukrainian conflict turned savage, and what it meant to be Russian and be a Russian rapper changed forever. While some rappers rejected Putin’s actions, others either endorsed Putin or stayed silent. Despite the foreignness of rap to the Russian nation, by studying Russian rap and its response to geopolitical unrest the Russian “popular” thought can be more accurately understood. To ascertain how the invasion was conceptualized and synthesized into rap by the Russian rap community, two Russian rap tracks (Oksimiron, Miron Yanovich Fyodorov, Oida and Husky, Dmitry Kuznetsov, God of War) were aesthetically and linguistically analyzed. Lying on divergent sides, they represent polar opposites of Russian rap, each encoding their worldview and position of Russian life in disparate ways, reflecting their respective political voice. While limited in scope, the study provides researchers one possible way to observe how Russian rappers internalize and then aestheticize their political beliefs into their musical style.

Post-bariatric hypoglycaemia (PBH) is typically a post-prandial hypoglycaemia occurring about 2–4 h after eating in individuals who have undergone bariatric surgery. PBH develops relatively late after surgery and often after discharge from post-surgical follow-up by bariatric teams, leading to variability in diagnosis and management in non-specialist centres.

Aim

The overall aim was to improve and standardise clinical practice in the diagnosis and management of PBH. The objectives were: (1) to undertake an up-to-date review of the current literature; (2) to formulate practical and evidence-based guidance regarding the diagnosis and treatment of PBH; (3) to recommend future avenues for research in this condition.

Method

A scoping review was undertaken after an extensive literature search. A consensus on the guidance and confidence in the recommendations was reached by the steering group authors prior to review by key stakeholders.

Outcome

We make pragmatic recommendations for the practical diagnosis and management of PBH, including criteria for diagnosis and recognition, as well as recommendations for research areas that should be explored.

Plain English summary

Post-bariatric hypoglycaemia (PBH) is a condition that commonly affects people who have undergone weight loss surgery. In this condition, people develop low blood sugar occurring about 2–4 h after meals, leading to debilitating symptoms such as hunger, sweating, anxiety, palpitations and even blackouts and fainting. PBH is becoming more common as weight loss surgery is being taken up by more people to help with their weight and to help with diabetes. The condition often develops after the patient has been discharged from follow-up after their surgery, which can lead to inconsistent diagnosis and treatment in non-specialist healthcare centres. The lack of clear information and evidence in the existing scientific literature further contributes to the variation in care. To address this problem, the Society for Endocrinology has created new guidelines to help healthcare professionals accurately diagnose and manage this condition. The guidelines were developed with input from dietitians, surgeons and doctors specialising in weight loss, and hormone specialists.
Evaluating Customer Experience Management in the Insurance Industry - Empirical Studies of Company and Customer Perspectives
Authors: Klopfer Lisa-Marie
Published: March 2024

Customer experience management has become a widely discussed topic within the insurance industry, with a growing number of insurers adopting the customer-oriented management approach to meet the challenges of today’s highly competitive market. As research and practice lack a comprehensive understanding of both the company and customer perspectives, this article contrasts insurers’ current efforts regarding the management approach with customers’ perceptions of their experiences. The results of an online survey among insurance companies show that insurers are in the midst of implementing the management approach, evaluating ist success using customer satisfaction and loyalty indicators. The proposed four-stage maturity model, which is developed on the basis of the survey data, can serve insurers as a decision-making tool to prioritize investments and activities regarding customer experience management. In a second online survey, insurance customers evaluate their experiences with their insurance provider. Structural equation modeling reveals that an effective customer journey design positively affects customer satisfaction and subsequently customer loyalty.

Authors: Hua Dongliang , Yuan Shuai , Zhao Yuxiao , Xu Haipeng , Chen Lei , Jin Fuqiang , Li Yan
Published: March 2024

Anaerobic digestion (AD) has been widely used as a promising technology for the treatment of kitchen waste (KW). The effects of several acidification-resisting methods were compared, which included the supplementation of trace elements (TEs) and zero-valent iron (ZVI) / powdered activated carbon (PAC), and the application of the sludge domesticated by acetic acid (HAc) and KW as inoculum. The results showed that the supplementation of TEs and ZVI/PAC at total solid (TS) content of 6% and optimal addition doses resulted in an increase in methane yield to 346 and 366 mL/g VS, respectively. In addition, the methane yields of 327 and 241 mL/g VS were obtained by applying the sludge domesticated with KW and HAc as inoculum, while the methane yield of the control was only 89.2 mL/g VS, representing a relative increase of 288%, 311%, 267%, and 170%. The acidification could be alleviated by applying these methods, and also the methanogenic profile was improved. Furthermore, microbial community analysis revealed that the enrichment of Methanosarcina, which enhanced the substrate utilization capacity and subsequently increased methane production, was achieved through the addition of TEs and ZVI/PAC, along with the application of sludge domesticated by KW.
Performance of laminated veneer lumber panels from fast-growing species with different layering arrangements
Authors: Arabi Mohammad , Hazrati Moharam , Rostampour-Haftkhani Akbar
Published: March 2024

This study investigated the effect of various layer arrangements and their impact on the properties of laminated veneer lumber (LVL). Seven different layer arrangements (CCCCCCC, DDDDDDD, PPPPPPP, CDDDDDC, CPPPPPC, CDDCDDC, CPPCPPC, CDCDCDC, CPCPCPC, CCDDDCC, CCPPPCC, CCDCDCC, and CCPCPCC) were used in the manufacturing of the LVL, with each arrangement represented by a combination of the three wood species: hornbeam (C), paulownia (P), and poplar (D). The veneers were bonded with a polyurethane adhesive and pressed under 1 MPa pressure. The physical and mechanical properties of the laminated veneer lumber, including modulus of rupture, modulus of elasticity, block shear, delamination, and swelling, were measured under both dry and cyclic conditions (boil and dry). The modulus of rupture and modulus of elasticity of the LVLs increased when the proportion of hornbeam in the lamination increased. In the cyclic boil-dry condition, the laminated veneer lumbers with the configurations CPCPCPC and CDCDCDC showed the best structural performance. Furthermore, the study found that when one or two upper layers of poplar and paulownia were replaced with hornbeam layers, cracks were observed in the laminated veneer lumber samples. However, when the layers of poplar and paulownia were replaced with hornbeam alternately, no cracks were observed after saturating the laminated veneer lumber with water. The utilization of an alternating arrangement of poplar and paulownia layers with hornbeam in LVL can be used as an effective and cost-efficient approach for enhancing and reinforcing the LVL performance.
Cationic Microparticle Retention Aids: The Mechanism Study and Laboratory Evaluation

The cationic polymeric microparticles (CPMP) with different charge densities and particle sizes were synthesized and characterized.The flocculation and retention of precipitated calcium carbonate {PCQ and titanium dioxide {TiO2) suspensions induced by a cationic polymeric microparticle retention system were studied in both the original and washed pulps. For the dispersion of PCC in the washed pulp, the CPMP alone is not an effective retention aid because both the CPMP and PCC are positively charged. However, the retention of fillers can be significantly enhanced by dispersing FCC in an unwashed pulp. The combination of CPMP and a high- molecular weight, water- soluble polymer led to excellent retention of PCC. Although both anionic or cationic polymers can be used in conjunction with CPMP, different mechanisms are involved in these dual-retention systems. For the dual-retention system of CPMP-APAM (anionic polyacrylamide), it is believed that a bridge is formed between the CPMP patch and APAM. In contrast to the CPMP-APAM system, the increase in the filler retention efficiency by the dual-retention system of CPMP-CPAM (cationic polyacrylamide) is not through the bridging formation between CPMP and CPAM, but is caused by the configuration change of the cationic polymer in the presence of CPMP. It is believed that the pre-adsorption of CPMP can prevent CPAM from getting flat on the solid surface, resulting in an extended polymer conformation and high retention efficiency. It has also been found that the particle size of a cationic polymeric microparticle is a critical factor affecting the PCC retention.

Microbial contaminants will decrease the quality of pigments and fillers in paper and board industry. Microbe-caused spoilage of these raw materials as well as indirect deteriorative effects of these spoiled additives on the machine housekeeping, production and hygienic properties of paper products are well-known problems at the mills. The traditional analysis of colony forming units helps both the manufacturer of raw material and his client to understand, what are the major contaminants and their densities in the raw material studied. These methods, unfortunately, are unsatisfying when rapid microbiological analyses are needed in urgent situations (trouble shooting, prevention of process contamination) . Their shortage as indicators of the effects of biocides on the activity of microbes is also evident . Three “rapid methods” were regarded as promising alternatives of colony count analyses in the control of paper and board machine’s processes: detection of microbial growth by impedance method or turbidity test and measurement of biomass by luminometric ATP assay . When tested for mineral additive control, difficulties were arisen in every case: inhibitive effect of sedimentation of the sample in direct impedance measurement, poor interpretation of slow growth responses in indirect impedance method and the adsorptive effects of turbidity on the light emission (ATP assay) or on the background absorbance (turbidometry) . For these reasons, strong dilutions of samples were needed and only high microbial densities (over 1000000 CFU/ml) were practically measurable by these methods. Integration of total impedance change may help to estimate low microbial densities by impedance methods, and more effective extraction and fractioning of microbial ATP may increase the sensitivity of ATP assay. Turbidometry seems to be a rather finished method, but its weak point is the long incubation period needed. Some efforts to develop all methods for the control of mineral additives seems thus to be necessary.
Post-Pandemic Public Space: How COVID-19 May Permanently Alter the Public Realm
Authors: Fisher Thomas
Published: March 2024

This research looks at the impact that pandemics can have on public space. The goal of the research was to learn from the past to anticipate the long-term effects of COVID-19 on the public realm. The research involved exploring the history of the effects of two major global pandemics – the 19th C. Cholera and the 20th C Influenza pandemics – as well as documenting the effects of COVID-19 as they occurred. The main finding of the research is that pandemics have long-lasting impacts on public space, although each has a somewhat different effect, depending upon whether it is bacterial or viral-based and how different countries and cultures respond. The research also shows that COVID-19 has been unique in rebalancing what we do in-person or remotely, physically or digitally, which will likely have profound effects on the use of public as well as private space. This, in turn, will demand a re-evaluation of public policies, many of which are based on pre-pandemic assumptions about in-person interactions as the primary way in which people work, shop, learn, and live.

Synthesis and investigation of dyeing properties of 8-hydroxyquinoline based azo dyes & 1-naphthylamine based azo dyes
Authors: Das Anik , Lei Xu
Published: March 2024

A facile and well-known synthetic strategy has been used to prepare this novel 8-hydroxyquinoline-based azo dye to apply as a disperse dye to polyester fabric. In this method, 8-hydroxyquinoline possessing a “privileged structure” which is made up of two rings, a phenol ring fused with pyridine ring, has been coupled with diazonium salt obtained from 1-Napthylamine. As-synthesized dyes are used as disperse to polyester fabric, and the dyed samples were characterized for color fastness to washing, rubbing, and perspiration. The fastness testing results indicate that the dyes have a good affinity to PET fabric as the dyed PET fabrics have moderate to excellent fastness to washing and perspiration and good fastness to rubbing. The dyeing property of 8-hydroxyquinoline-based dyes is very promising and can be considered as the potential candidate to meet the actual demand of PET fabric dyeing in the textile industry.

Phytochemical, Vitamins and Toxic level of processed Cocoyam inflorescence were determined. Samples of cocoyam inflorescence were processed by blanching, soaking, Boiling, sun drying, and oven drying. Fresh sample of Cocoyam inflorescence was analyzed and stands as the control. All the chemical analysis was determined, using standard analytical method. Processing methods caused significant (p<0.05) reduction on the Vitamins, phytochemical composition and toxic components of cocoyam inflorescence. Pro vitamin A content of fresh sample was 348.91µg/dl while Vit. E, B2 and C were 16.82, 12.59 and 27.21 mg/100g respectively. The fresh sample showed 114.01, 586, 1.52, 36.07, 254.24, 32.27 and 32.87% respectively for flavonoid, carotenoid, phenol, oxalate, steroid, phytate and alkaloid contents. Water blanching and oven drying showed significantly (p<0.05) reduction in Vit. E, B2, C and pro vit A by 83.5, 79.1, 98.6 and 95% respectively. Boiling and sun drying caused significant (p<0.05) reduction in alkaloid, flavonoid, carotenoid, saponin, phenol, oxalate, steroids, phytate and tannin content by 95.8, 83.2, 94.4, 74.6, 45.4, 43.1, 87.2 and 97.8% respectively. These results showed that fresh Cocoyam inflorescence contains appreciable amount of vitamins with moderate level of phytochemicals. The highest dosage of 5000 mg/kg body weight of cocoyam inflorescence extract had no significant (p<0.05) toxic effect on the tested animals. Petroleum ether extract showed the presence of rich variety of the secondary metabolites. Boiling with sun drying showed higher losses of vitamins and phytochemical composition of Cocoyam inflorescence while boiling with oven drying showed better retention of these bioactive components in Cocoyam inflorescence.

Authors: Peña Baracaldo Fernando Javier , Africano Franco David Ricardo , Moreno-Ortiz Carlos Alberto
Published: March 2024

The blueberry industry is growing significantly in Colombia. For investors, cost analysis plays a key role in project planning for any agribusiness. This paper is an exploratory study, with a descriptive scope to identify components of establishment and production costs of growing blueberries in Colombia. Data were collected and analyzed from a project aimed at establishing a 1 ha blueberry crop in Zipaquirá and 18 blueberry small farms in the Cundiboyacense highlands. Components were applied to estimate the capital investment and to identify the establishment, production, and maintenance costs of this project. Decision investment analysis, including discount rates for the capital asset pricing model (CAPM), were used to compute the net present value (NPV), internal rate of return (IRR), and the return on investment (ROI). Production costs are still expensive due to the Colombian peso (COP) exchange rate compared to the US dollar (USD). Results show advantages for promoting the establishment of blueberry crops because of suitable climatic conditions for continuous production throughout the year in Colombia. Labor costs and utilities are cheaper compared to other countries and represent a competitive advantage in the investment. Intermediation suppliers affect establishment costs for commercial reasons. Blueberry production cost analysis in Colombia may facilitate agribusinesses to promote projects in Colombian agriculture.

Authors: Pérez Analía Fernanda , Fraysse Cintia Pamela , Ojeda Mariel
Published: March 2024

Introducción: Los equinodermos son dominantes en términos de abundancia y diversidad; particularmente los asteroideos presentan un importante rol en las comunidades bentónicas antárticas.

Objetivo: El objetivo del presente trabajo fue revisar la distribución batimétrica, composición específica, ocurrencia y riqueza de especies de asteroideos que habitan en los archipiélagos Orcadas del Sur, Shetland del Sur y Archipiélago de Palmer, ubicados en la Península Antártica. A su vez, detallar aspectos de los patrones de desarrollo de las especies halladas.

Métodos: Utilizamos la información adquirida durante Campañas Antárticas de Verano 2012 y 2013, a bordo del Buque Oceanográfico “Puerto Deseado”. Las estaciones de muestreo se ubicaron en tres archipiélagos localizados en la Península Antártica: Orcadas del Sur (OS), Shetland del Sur (SS) y Archipiélago de Palmer (AP). Se realizaron 28 lances de pesca y se fotografiaron y procesaron 436 individuos. Se determinó el radio mayor (mm) de cada individuo, las características macroscópicas de las gónadas y la presencia de embriones. Se realizó una revisión del estatus taxonómico y de la distribución batimétrica y del área de distribución geográfica de las especies muestreadas basándonos en registros bibliográficos y bases de datos. Se utilizó una agrupación jerárquica para analizar la composición de las especies entre las diferentes áreas.

Resultados: En todas las estaciones de muestreo se obtuvieron asteroideos (ocurrencia: 100 %) entre 52.7 y 987 metros de profundidad. Se registraron 21 especies, de las cuales no se modificó la distribución batimétrica de ninguna de ellas, pero se amplió el área de distribución geográfica de seis. La riqueza de especies fue igual en SS y AP, y mayor que en OS, coincidiendo con la presencia de dos grupos regionales con una composición faunística similar. El 72 % de las especies registradas presentan desarrollo pelágico (larva planctotrófica = 17 % y larva lecitotrófica = 55 %) y el 28 % desarrollo no pelágico (larva retenida = 17 % y desarrollo directo = 11 %).

Conclusiones: En los tres archipiélagos el patrón de desarrollo mayoritario fue el pelágico con nutrición lecitotrófica. La totalidad de las especies halladas en el presente trabajo son compartidas con la región subantártica, destacándose la importancia de la Corriente de Malvinas en la dispersión de las especies desde Antártida.
Effect of gamete aging on fertilization success of the sea urchin Arbacia dufresnii (Arbacioida: Arbaciidae)
Authors: Fernández Jimena Pía , Di Marco Florencia , Rubilar Tamara , Cledón Maximiliano , Gonzalez Pisani Ximena
Published: March 2024

Introduction: Short-term gametes storage is an inexpensive and simple technique that allows the use of the same batch of eggs or sperm at different times, maximizing the application of research protocols and the use of gametes in production. Arbacia dufresnii is a sea urchin species with proven aquaculture potential and already used in the nutraceutical industry. Aging of its gametes is unknown and is a needed information to scale up the production.

Objective: Determine the effect of male and female gamete aging on the fertilization success of Arbacia dufresnii. This will allow optimizing the use of gametes after collection decoupling spawning from fertilization.

Methods: A. dufresnii individuals were induced to spawn and gametes were kept at 12 ± 1 °C throughout each bioassay. Sperm was separated into two treatments: activated sperm in seawater (AS), and dry sperm (DS). Two bioassays were made: Bioassay 1 evaluated the effect of time on fertility by performing fertilization tests at 0 h, 24 h, 48 h, 72 h, and 96 h after spawning. Bioassay 2 evaluated the contribution of each type of aged gamete on fertility, combining aged gametes (96 h) with fresh gametes (0 h).

Results: Bioassay 1: the fertilization success obtained by combining eggs (E) with AS or DS presented important differences. While the fertilization success remained acceptable (greater than 50 %) for up to 72 h using ExDS, it only remained acceptable for up to 48 h using ExAS. Bioassay 2: acceptable fertilization success was found by combining aged E (96 h) with fresh sperm, or aged DS (96 h) with fresh E, but not using aged AS with fresh E.

Conclusions: The findings of this work show that fertilization success in A. dufresnii gametes remains relatively unchanged for up to 48 h after spawning when combining ExAS, and for up to 72 h when combining ExDS. However, when combining aged E or aged DS with a fresh gamete, post-collection fertilization can be extended up to 96 h. In this work, the first steps have been taken to understand the conservation time of A. dufresnii gametes with minimum intervention.

Artifacts Associated with the Chemical Arts in the Early Islamic Period in Ramla, Israel
Authors: Gorzalczany Amir , Rosen Baruch
Published: March 2024

Archaeological excavations in Ramla, Jund Filastin capital during the early Islamic period, discovered in a zone of artisans and workshops, a unique complex of built and dug installations. It included barely known and understood components of a proto-chemical toolkit. The finds included an abundance of small, decorated bottles previously identified as perfume containers. Additional small finds of a proto-chemistry toolkit included e.g., bronze pipettes, delicate bronze pestles and weights. The complex is to be associated with the existence of a facility differing from an alchemist studio-laboratory. It involved the commercial, non-artisan, pre-industrial production of perfumes and aromatic oils associated with body care chemistry. The close proximity to a Hammam (bathhouse) is notable. Suitable comparisons were found throughout the Mediterranean Basin, from Spain, where comparable tool kits in close proximity to Hammams were discovered, to Russia, where similar technology and typology were documented. The article discusses the importance of the dictates of the Qur’an and Mohammedan traditions regarding purification of the body and their catalytic influence on social and early technological changes in a pre-industrial society.
The “Halep Arki” (Aleppo Channel), a Mamluk Era Water System for Aleppo
Authors: Demir Timur , Ekici Bulut Makbule , Redford Scott
Published: March 2024

Due to its low rainfall and limited potential for water retention, northern Syria has always had access to and control of water as one of the main features of states in the region aiming to maintain their rule. This article introduces new information about the Mamluk period water adduction system of the northern Syrian city of Aleppo, which brought water to the Quwayq River, the city’s most important source of water. A newly documented part of the system, known in the Gaziantep region of Türkiye as the “Halep Arki” (the Aleppo channel), is discussed along with Mamluk-era inscriptions associated with it. During archaeological survey conducted between 2016 and 2018 in the Oguzeli region of Türkiye’s Gaziantep province, an open-air channel connected to a qanat-like tunnel with vertical shafts was documented, in addition to two inscriptions carved into the bedrock where the open-air channel met the tunnel. These inscriptions, which have been damaged over the centuries, were documented using RTI (Reflectance Transformation Imaging) technology, which allowed portions of one of them to be read. The survey showed that this Mamluk era water system was also used and expanded in the Ottoman period beginning with the conquest of the region in the 16th century. Spoil heaps show that the system was cleaned, likely during the Ottoman era. The closing of gaps in the bedrock that came about due to earthquakes or other reasons with stone walling may also have taken place in the Ottoman period. Also, in the Ottoman period, water from other springs was added to the system and various regulations on the use of water introduced. In this article, based on topographic and hydrological study of the region, we offer suggestions of the sources of the spring water that were joined to this system.

SYNTHESIS OF NICKEL-DOPED BIVO4 MATERIALS BY HYDROTHERMAL METHOD AND EVALUATE THE PHOTOCATALYTIC ABILITY TO DECOMPOSE METHYLENE BLUE UNDER VISIBLE LIGHT
Authors: Pham Van Thinh , Dao Thi Bach Tuyet , Tran Thi Kim Ngan , Tran Ngoc Quyen , Bach Long Giang
Published: March 2024

Ni-doped BiVO4 photocatalysts were successfully synthesized by hydrothermal method. The catalytic samples were characterized by scanning electron microscopy (SEM), UV-vis diffuse reflection spectroscopy (DRS), photoluminescence spectroscopy (PL) and X-ray diffraction (XRD). Based on the results of PL spectrum analysis, the electron-hole recombination phenomenon is limited by the presence of the second metal Ni in the structure at Bi3+ positions. The catalyst materials at the Ni doping ratios all have the monoclinic-scheelite BiVO4 structure as shown by the XRD and Raman methods. The photocatalytic ability of methyl blue (MB) on the Ni/BiVO4 catalyst was studied under visible light irradiation in order to contribute to reducing the current environmental pollution problem. The removal efficiency of MB varies with the doping ratio of Ni/BiVO4, reaching the highest decomposition efficiency of 84.77% in the 5% mol Ni sample, which is 30% higher than that of the BiVO4 sample. The BiVO4 material modified with Ni gives a high photocatalytic efficiency of organic pigment decomposition under visible light indicates the potential improvement in the efficiency of a material for existing applications and exploit many new applications in the future.

The present paper is focused on the problem of consecrated virginity. A consecrated virgin is a sign of Church’s love for Christ, what situates the consecrated virgin in the community of the Church essentially as a prophetic person and a kind of example for other faithful. Her virginity, which is her characteristic feature, is for her both a gift from God and a task to realize within her vocation. Consecration of a virgin means the establishment of a spousal covenant between her and Christ. Therefore the first paragraph focuses the attention on Christ as a Bridegroom both of the Church and of every Christian, and finally of every consecrated virgin. The second paragraph discusses the virginity as a gift both to Mary and to the Church, as well as to the consecrated virgin. The third paragraph deals with the tasks of the consecrated virgin resulting from her virginity. The present paper is the ninth Author’s publication concerning the individual forms of consecrated life. The presented viewpoint is a formational proposition for both consecrated virgins and candidates for consecration.

Data on the regional composition of mixed marine aggregations of juvenile pink salmon during postcatadromous migrations in the basin of the Sea of Okhotsk in 2022 are demonstrated. A high probability of a significant predominance is revealed for pink salmon spawning returns 2023 of the northern stock complex compared to the southern ones. Identification estimates for juvenile fish obtained from RFLP analysis of mtDNA and analysis of allelic variability of SNP loci are compared to the values of actual regional catches and spawning returns. Close correspondence between the calculated estimates and actual data on the results of the 2023 fishing season was noted. Forecast about predominance of pink salmon of the northern stock complex, as well as about atypically low proportion of fish from water bodies of Iturup Island is fully confirmed. The estimates for Sakhalin Island and the southern part of the continental coast of the Sea of Okhotsk are close to the actual catch.

Exploring the Differences in Learning Strategy Use Between Online and Offline Classes
Authors: Park Eun Hwa
Published: March 2024

The purpose of this study was to explore whether there is a difference between online and offline classes in the degree of learning strategies that learners use for learning outcomes and whether there is a connection between learning strategies used in online and offline classes. A total of 81 college students, taking liberal arts English classes—Reading and Writing Practice, TOEIC Beginner, Let’s Know Two-Word Verbs, and ESP Reading and Writing—answered questions based on the learning strategies scales from the Motivated Strategies of Learning Questionnaire (MSLQ) by Pintrich et al. (1991). There was a total of 30 questions related to rehearsal, elaboration, organization, critical thinking, and metacognitive self-regulation. The results showed that there was no significant difference between online and offline classes in learning strategies used. It was further found that there were highly significant relationships among the learning strategies used in online and offline classes. Although there was no difference in strategy use between online and offline learning, this current study found out that the level of the strategy uses and the relationship between strategies used was significant. This study emphasizes that the use of learning strategies should be presented according to the context and learning environment.

Published: March 2024

The study analyzed educational migration in Russia. Migration is considered from the standpoint of an integrated indicator that reflects complex socio-economic processes in society. The factors of territorial mobility of the population are listed. Under their influence, the directions, dynamics, intensity and consequences of migration for donor and recipient countries change. The place and role of educational migration in the modern world are shown. The study examined the structure and dynamics of the number of foreign students studying in the universities of the Russian Federation. The directions of tough competitive struggle of national educational models in the international market of educational services and rating indicators for evaluating the activities of universities are analyzed. It is noted that the West conducts unfair competition in relation to Russian universities and the entire education system, which manifests itself in sanctions pressure, the exclusion of Russia from the Bologna process, the refusal to nostrify educational documents, etc. It is emphasized that external educational migration to a certain extent can be considered as a form of brain drain. The largest recipient countries of foreign students are indicated, which include the USA, Great Britain, China, Canada, Australia, and France.
