Role-based access control in cloud-native applications: Evaluating best practices for secure multi-tenant Kubernetes environments
Authors: Charan Shankar Kummarapurugu
Published: November 2024

As cloud-native applications grow in complexity and adoption, particularly within multi-tenant Kubernetes environ- ments, security and access control mechanisms are paramount. Role-Based Access Control (RBAC) is increasingly utilized as a critical security framework to manage permissions across users and services in these cloud-native platforms. However, implementing RBAC in Kubernetes presents unique challenges, especially in multi-tenant setups where robust access separation and efficient permission management are essential. This paper explores best practices for RBAC in multi-tenant Kubernetes environments, highlighting architectural design principles, po- tential vulnerabilities, and mitigation strategies. We propose an optimized RBAC model tailored for cloud-native applications, emphasizing role hierarchies, namespace isolation, and scalable access management. Our approach aims to enhance security by reducing the risk of privilege escalation and ensuring compliance with security policies across tenant boundaries. Experimental evaluation demonstrates the effectiveness of our model in min- imizing security risks and providing scalable access control in Kubernetes clusters. These findings offer actionable insights for organizations seeking to secure cloud-native applications in shared and multi-tenant infrastructures.
A Comparative Analysis of OAuth 2.0 and OpenID Connect for Identity Federation in Cloud Environments
Authors: Charan Shankar Kummarapurugu
Published: November 2024

In cloud computing, secure and efficient identity federation is crucial to providing users with seamless access across distributed resources. As cloud ecosystems grow, so does the demand for protocols that can manage identity verification and access authorization in a scalable and secure manner. OAuth 2.0 and OpenID Connect are two of the most prominent protocols enabling identity federation, though they address distinct aspects of identity management. OAuth 2.0 primarily facilitates secure delegation of access permissions without sharing user credentials, making it a reliable choice for resource access in distributed systems. Conversely, OpenID Connect builds on OAuth 2.0 by introducing an authentication layer that verifies user identities, thus enhancing security for applications where user verification is required. This paper provides a comparative analysis of OAuth 2.0 and OpenID Connect, focusing on their architectural designs, security features, and performance in cloud-based applications. Using metrics derived from real-world cloud scenarios, this study examines each protocol’s scalability, vulnerability to security threats, and efficiency in high-demand environments. The results indicate that OAuth 2.0’s architecture supports higher scalability and lower latency, suitable for environments prioritizing efficiency. OpenID Connect, while introducing some computational overhead, provides added layers of identity security, which is critical in applications requiring strong user authentication. This analysis offers a framework for selecting the appropriate protocol based on specific cloud environment needs, whether prioritizing performance, scalability, or identity verification.
ETL and data virtualization
Authors: Nishanth Reddy Mandala
Published: November 2024

As organizations continue to adopt modern data architectures, the convergence of traditional ETL (Extract, Transform, Load) processes with data virtualization has emerged as a promising solution for integrating and managing complex data environments. Data virtualization allows real-time data access without physically moving the data, while ETL provides the foundation for data transformation and integration. This paper explores the integration of ETL and data virtualization, its benefits, and challenges, and provides insights into how businesses can leverage this approach to create a unified data management strategy.

Published: November 2024

The efficient and useful conversion of kitchen waste into biogas will mitigate the health and environmental challenges caused by their indiscriminate disposal. This study compared the potential yields of biogas from plantain peels chaff (P) and bean peels chaff (B) when anaerobically digested in singles and when combined, and when digested in different slurry concentrations. Two combinations of the substrates were used; PB1 consisted of P and B combined in the ratio of 1:0.691 respectively, while PB2 had an equal ratio (1:1) of P and B. The substrates were digested anaerobically in three slurry concentrations representing substrate/water mixing ratios of 1:5 (S1), 1:10 (S2) and 1:15 (S3). The substrates were digested for thirty-seven days after augmentation with cow rumen liquor. Proximate analysis of the substrates was also done. Biogas was collected using the water displacement method. Results revealed that the total solids (%) of the substrates were 90.12 (P), 96.03 (B), 84.15 (PB1), and 84.94 (PB2). The carbon/nitrogen (C/N) ratios ranged from 9.04 to 15.3. PB1 yielded the highest mean volume of biogas per day (10.8 cm3/day) while P yielded the least (8.07 cm3/day). Results revealed that biogas yields increased as slurry concentration increased. The difference in yields with respect to co-digestion was not significant, whereas the difference with respect to slurry concentration was highly significant. We conclude that the peels of Musa paradisiaca and Phaseolus vulgaris could be converted into biogas whether digested individually or combined, and that higher slurry concentrations are recommended for a higher production of biogas.
Mental health issues in women diagnosed with infertility or multiple failed IVF attempts
Authors: Sobotie Stephanie Efua
Published: November 2024

This article examines the relationship between infertility and mental health in women, highlighting the bidirectional nature of this interaction. Infertility often leads to psychosocial issues such as depression, anxiety, and sexual dysfunction, significantly reducing the quality of life for patients. This paper also presents a literature review to provide a theoretical foundation on the topic, encompassing controlled randomized trials, population cohort studies, and cross-sectional studies. The research covers data on the prevalence of mental disorders, loss of a sense of control, and sexual dysfunction among women experiencing prolonged infertility, particularly after unsuccessful in vitro fertilization (IVF) cycles. The results indicate that 60% of patients suffer from depression, and 75% experience sexual dysfunction as well as anxiety disorders. Moreover, significant differences in mental disorder levels between groups underscore the need to integrate mental health support into infertility treatment protocols to improve patients' overall well-being. These findings support the necessity of providing psychological support for women suffering from infertility and multiple failed IVF attempts.
Higher education reform in Morocco: Challenges, insights, and global perspectives
Authors: Sarah Houssami
Published: November 2024

This paper explores the evolution and challenges of higher education, with a particular focus on Morocco. Beginning with a historical overview, it traces the development of the modern university and its mission as defined by key figures such as Wilhelm von Humboldt and John Henry Newman. The paper examines how these ideas have shaped global higher education systems, including the Moroccan context. It highlights the persistent challenges in Moroccan higher education, such as outdated curricula, ineffective reforms, and the widening gap between graduates’ skills and job market demands. Despite various reform efforts, including the adoption of the LMD (‘Licence-Master-Doctorat’) system, the paper argues that these initiatives have not fully addressed the structural deficiencies and have struggled to keep pace with globalization and labor market changes. Additionally, the paper discusses the tension between public and private higher education models, the issue of brain drain, and the growing importance of English as a global lingua franca in Moroccan universities. By drawing on both Moroccan and international examples, this study highlights the need for continuous, adaptive reforms that emphasize interdisciplinary learning, practical training, and stronger public-private partnerships. Ultimately, the paper calls for a holistic approach to reforming higher education in Morocco to ensure it serves as a public good and remains relevant in the global economy.

Authors: Yolenta Alina Hale  , Antonius Lucky Arnando  , Agung Krismariono
Published: November 2024

Introduction: Pulp and periodontal tissues have embryonic, anatomical, and functional attachments so that infections can easily spread to each other. Endo-perio lesions are commonly found in teeth with pulp necrosis, especially involving the furcation area. The lateral connecting channel between the pulp tissue and the periodontal tissue causes this condition. Case Report: A 20-year-old healthy male came with the main complaint of a loose lower right back tooth and bleeding gums when brushing his teeth. Intra-oral examination revealed plaque and BOP (+) in all dental quadrants, caries, and grade 2 mobility in tooth 46. The treatment plan in Periodontology is regenerative surgery on tooth 46. Case Management: Flap surgical therapy was performed on tooth 46 with granulation tissue debridement, bone graft, and membrane application to the furcation area. Conclusion: Treatment of furcation involvement by regenerative therapy using bone graft and membrane can provide good results in endo perio lesions. The key to successful treatment in this case is a combination of endodontic treatment and periodontological treatment.

Published: November 2024

У статті розглядається потенціал технологій штучного інтелекту (ШІ) у інтерпретації до військових операцій. Досліджуються ключові можливості ШІ, які можуть змінити способи ведення війни, зокрема автономні бойові системи, інтелектуальні транспортні системи, обробка великих даних, прогнозування, інтелектуальні системи управління боєм, підвищення ефективності логістики та кібербезпека. Автономні бойові системи, включаючи бойові дрони та наземні роботизовані платформи, здатні виконувати розвідувальні та ударні завдання, знижуючи ризики для особового складу. Інтелектуальні транспортні системи, такі як автономні конвої та безпілотні літальні апарати, оптимізують логістичні операції та забезпечують точні дані про обстановку. Обробка великих даних дозволяє інтегрувати інформацію з різних джерел для покращення ситуаційної обізнаності, а алгоритми прогнозування допомагають передбачати рухи противника та моделювати бойові сценарії. Інтелектуальні системи управління боєм надають командирам рекомендації на основі аналізу даних, сприяючи прийняттю обґрунтованих рішень. Використання розширеної та віртуальної реальності покращує підготовку персоналу та ситуаційну обізнаність на полі бою. Логістика виграє від автоматизації складів та оптимізації ланцюгів постачання, що підвищує ефективність використання ресурсів. Кібербезпека стає критично важливою з огляду на зростання кіберзагроз, і ШІ відіграє ключову роль у захисті військових систем від атак. Інформаційні операції також використовують ШІ для аналізу та протидії дезінформації. Однак впровадження ШІ у військовій сфері стикається з технічними, організаційними та етичними викликами. Важливо забезпечити належний рівень безпеки, підготовки персоналу та дотримання етичних норм. Стаття підкреслює, що ШІ може значно підвищити ефективність військових операцій, зменшити втрати та забезпечити стратегічні переваги, але потребує обережного та відповідального підходу.

A COMPARATIVE ANALYSIS OF METAPHORS IN AHMET HAMDI TANPINAR’S NOVEL HUZUR AND VIRGINIA WOOLF’S NOVEL MRS. DALLOWAY
Authors: İnan Dilek , Eser Kadriye Tilbe
Published: November 2024

Ahmet Hamdi Tanpınar's novel Huzur and Virginia Woolf's novel Mrs. Dalloway depict the adverse consequences of the post-war period within and between societies. The novels, from diverse cultural backgrounds, portray the traumas of individuals and the characteristics of modernism. Huzur from Turkish literature and Mrs. Dalloway from English literature, apply metaphors to illustrate the atmosphere during the post-war period. Metaphors arise from experiences, and it is a way of understanding one domain through the lens of another. Metaphors are often inherent in everyday language and are often used unconsciously; whereas those found in literature are generally treated with artistic intent. As both novelists are critical of physical and psychological disorders of post-war experience, the paper elaborates on “Life is a War” conceptual metaphor inspired by Lakoff and Johnson’s metaphor index. The study focuses on a comparative analysis of conceptual and linguistic metaphors in Huzur and Mrs. Dalloway considering modernist elements in the novels.
STRUCTURAL CONTROL OF SEISMIC ACTIVITY ALONG THE SOUTHEASTERN EDGE OF THE BUREYA MASSIF

Published: November 2024

Analysis of the relief and geophysical fields showed the seismic zone of the southeastern margin of the Bureya massif to be confined to the ring structure, where signs of shear deformation were revealed: displacement of submeridional structures by northeastern faults, an oblique mantle detachment. The gravity field analysis indicates that strike-slip displacements were initiated by NE- and NW-oriented heterogeneities. Anomalies of the released seismic energy are also of NE and NW directions, but the intensity and the size of the first direction are much greater. The strongest seismic sources with M ≥ 5 are confined to deep NE intense gravity anomalies suggesting that activation of northeastern structures in this seismic zone is the main process. The area where sources with 5 > M ≥ 4 cluster on the surface is confined to the narrow depression formed above the edge of the deep NW-oriented intense anomaly which tends to pinch out laterally. In the near-surface horizons, according to the gravity field analysis data, submeridional anomalies are displaced by NE-oriented structures to form a transtensional fault. Thus, the area of enhanced seismic activity represents a tectonic center with NE- and NW-oriented structures aligned. These structures initiate rotational and shear deformations, which probably reflects the joint influence of the collision between the Indian and Eurasian plates, on the one hand, and the Pacific subduction zone, on the other, on intraplate processes.

Authors: Arroyave-Durán Cristhian David , Vallejo-Valderrama Karina , Castillo-Clavijo José Luis , Figueroa Luis Mauricio
Published: November 2024

Introducción. Los tumores de células yuxtaglomerulares, también denominados reninomas, representan una causa poco frecuente de hipertensión arterial secundaria en la población pediátrica. Se sospechan ante la presencia de cifras tensionales elevadas, refractarias al manejo farmacológico, con elevación de renina plasmática e hipopotasemia. El objetivo de este artículo fue presentar el caso de una paciente de 17 años con diagnóstico de tumor de células yuxtaglomerulares, tratado con cirugía preservadora de nefronas.
Caso clínico. Paciente que cursó con crisis hipertensiva y en el estudio de causas secundarias se identificó elevación de la renina plasmática e hipopotasemia, que persistió luego del ajuste de la terapia antihipertensiva. Los estudios imagenológicos identificaron una lesión renal izquierda, nodular y sin extensión a estructuras adyacentes.
Resultados. Fue llevada a tumorectomía usando ecografía intraoperatoria y se resecó una lesión de la cara posterior del polo inferior renal, cuya biopsia por congelación fue negativa para células blásticas. La patología quirúrgica y el análisis inmunohistoquímico fueron compatibles con tumor de células yuxtaglomerulares. En el postoperatorio temprano desarrolló un urinoma, que fue manejado mediante tutorización urinaria con catéter doble J.
Conclusiones. Aunque se trata de una etiología infrecuente para hipertensión secundaria, debe ser considerado entre los diagnósticos diferenciales de hipertensión renina-dependiente. Se ha reconocido la resección quirúrgica como el manejo estándar, con intervenciones que van desde la nefrectomía abierta hasta la cirugía preservadora de nefronas mínimamente invasiva, con la que se logra, posteriormente, el control de las cifras tensionales.

Authors: Henry Enyi Chika , Adeyinka Ibianga Gift
Published: November 2024

Despite the flow of FDI in Nigeria, there is still high rate of unemployment, leading to greater level of insecurity, banditry, kidnapping etc. Until adequate economic investments are actualized, it will be difficult to achieve and measure both human and material resources. The study investigated the relationship between foreign direct investment and economic growth in Nigeria using ex-post-facto research design. The time series data used covered the time period 1990-2022. The data were obtained from the Annual Statistical Bulletin of the Central Bank of Nigeria. The population for this study consists of the national economic data that is pertinent to this research. However, this limitation applies specifically to foreign direct investment, which includes both oil and non-oil foreign direct investment, as well as economic growth measured by real gross domestic product (RGDP). In line with the positivist investigation ethic and quantitative design, this study use parametric statistics as the technique for inferential analysis. This technique involves the utilisation of quantitative models to determine the connection between two variables. It uses sample-based parameters as metrics to make inferences about the population being studied. The analysis was conducted with linear regression. The analysis confirmed a substantial correlation between characteristics related to foreign direct investment and economic growth. Consequently, the study demonstrated a substantial and favourable correlation between variables related to foreign direct investment and economic growth. Hence, the study recommends that policymakers should formulate policies that both encourage foreign investment and safeguard and enhance domestic production and investment. These policies should align with the development objectives of the host countries. The Nigerian government should prioritise substantial investments in non-oil sectors like agriculture and mining to generate a multiplier effect and boost the productive capacity of non-oil exports. This will contribute to the long-term economic growth and sustainability of Nigeria.

Authors: Alharbi Ziyad Salem Awad
Published: November 2024

Numerous risks associated with petrochemical projects can lead to cost overruns and negatively impact the quality of petrochemical products. These problems result from a failure to implement a plan to manage risks related to the operation and maintenance of petrochemical equipment and machinery. Therefore, this study aims to examine the risk mitigation strategies represented by risk retention, risk control, risk prevention, and risk transfer related to improving the financial aspects of petrochemical projects. To achieve the research objectives, the study relied on the quantitative approach by using a questionnaire that included the definition of all potential risks related to operational, human, environmental, and maintenance risks. The questionnaire also included an extensive study of risk mitigation strategies. The organization distributed the questionnaire to 268 Sankyu Company employees who operate and maintain petrochemical equipment. The study sample reached 159 respondents. The SPSS statistical analysis program calculated averages and standard deviations after collecting the data. The study found that the potential risks assessed using the risk index have a significant impact on petrochemical projects. The study also provided a comprehensive guide that includes risk mitigation strategies in petrochemical projects. The study has proven effective in improving the financial aspects of petrochemical projects.

Neuroscience and climate action: intersecting pathways for brain and planetary health
Authors: Todorova Boryana , Steininger Maximilian Oscar , Lamm Claus , Doell Kimberly C
Published: November 2024

The climate crisis and the human brain are intricately connected. Climate change impacts neurocognitive health, while climate actions both shape and are shaped by the brain. However, research examining these connections remains scarce. This review highlights how neuroscience can deepen the understanding of the reciprocal relationship between climate action and the brain. First, we discuss how both individual and collective climate action can directly and indirectly benefit our brain health, mental health and cognitive functioning and how emphasising this holds the potential of harvesting self-interest as a driving force for change. Second, we explore the role of the brain’s emotional and decision-making systems in motivating climate action. We also highlight neuroscience’s potential to predict population- level behaviours and aid in the systematic development of interventions. By addressing current knowledge gaps, we identify the next steps for deepening our understanding of the interwoven connections between climate action and the brain.

Coarse grain is obtained at the weld nugget in the FSW and finer grain is obtained in case of TIG Welding. Weld is less brittle in FSW than TIG Welding as the % elongation is 3.24 in FSW and 0.76 in TIG welding.
The Optimal Placement of a Photovoltaic-integrated Dynamic Voltage Restorer for the Enhancement of Power Quality within the Distribution System: A Case Study of 11Kv Simara Industrial Feeder in Nepal
Authors: Dhakal Prabin , Gautam Basanta kumar
Published: November 2024

Power Quality (PQ) issues like voltage sag, swell, and harmonics in electric power systems, especially those with an unbalanced radial network structure, dynamic compensation mechanisms are essential, particularly for industrial loads susceptible to voltage fluctuations due to faults or overloads. Dynamic Voltage Restorers (DVRs) have been proposed as a viable solution. However, when integrated into a distributed network, it becomes crucial to determine the optimal placement to maximize system performance. This paper focuses on a Photovoltaic (PV) system integrated DVR using Space Vector Transformation (SVT) with a Proportional Resonant (PR) Controller Control strategy. The primary objective is to minimize the System Average RMS Variation Frequency Index (SARFI) within the system of interest by identifying the optimal location of DVR. To assess the effectiveness of the proposed scheme, a functional PV-DVR model was developed using the MATLAB2023a/SIMULINK simulation environment. This model was implemented to dynamically restore node voltages to their pre-fault conditions in response to faults or overloads. The simulation results are presented for both an IEEE 13-node test distribution system and a 50-node typical radial industrial distribution system operating in Nepal. These simulation results serve to demonstrate the effectiveness and practicality of the proposed approach in mitigating power quality issues within electric distribution systems, thereby ensuring uninterrupted operation for critical industrial loads.
Acquisition of L2 English Negative Quantifiers without Equivalent Lexical Items in an L1
Authors: Kamiya Masaaki , Guo Zhaosen
Published: November 2024

This article investigates how second language learners interpret a scope bearing item in the target language. According to Sprouse (2006), L2 learners’ task is to relabel their native language’s lexical items in line with the features of the target language. An interesting lexical item is the English negative quantifier, for which there is no equivalent in Japanese. It was discovered that the default interpretation of the English negative quantifier by Japanese-speaking learners of English was a narrow scope reading (i.e., Quantifier Raising (QR) does not occur). We follow Beghelli and Stowell’s (1997) elaborated functional structures for quantifier feature checking at Spec-Head agreement. Because Japanese is considered to be a “no agreement” language (Kuroda, 1992; Fukui & Sakai, 2003), QR is failed since the English negative quantifier cannot satisfy “agreement” for the feature-checking. Hence, even if the equivalent lexical item does not exist in Japanese, a grammatical constraint such as “no agreement” is transferred to the initial state of the second language (Full Transfer in Schwartz and Sprouse, 1996).
Digital Game-Based Language Learning (DGBL): An Analysis of Polish and Spanish Teacher Candidates’ Knowledge and Attitudes
Authors: Belda-Medina Jose , Poveda-Balbuena Miguel Luis
Published: November 2024

The digital gaming industry is experiencing rapid growth and presents significant potential for implementation in educational contexts. Despite a significant body of literature on Digital Game-Based Language Learning (DGBL), the focus has primarily been on students as game players rather than on teacher candidates as future educators. This study aimed to examine the attitudes and knowledge of 205 teacher candidates from Poland (n = 79) and Spain (n = 126) regarding digital games’ potential for foreign language learning. Convenience sampling was used, and a mixed-method approach was taken to collect quantitative and qualitative data via pre-post surveys, digital game presentations, and class discussions. Participants undertook various DGBL activities and were grouped into teams to choose games for language learning, create infographics, and share their insights in a collaborative learning environment. Statistical analysis indicated differences in the first-time technology access and gameplay frequency between the Polish and Spanish cohorts. The Wilcoxon-signed rank test revealed a significant difference (p ≤ 0.05) in two of the five scale dimensions: usefulness (U) and preference for digital games (PDG). The findings suggest that while teacher candidates hold a positive view of DGBL’s potential, they lack practical knowledge of its implementation in the language classroom.
The Cultural Component of Selected LSP Textbooks in the Area of Business and Their Potential for Developing Intercultural Competence
Authors: Wlosowicz Teresa Maria
Published: November 2024

The article aims to investigate the cultural component of selected LSP textbooks in Business English, German, French and Spanish from the point of view of their potential for developing intercultural competence, which is indispensable in business communication (Stegu, 2017). The study analyses the cultural content of twenty textbooks as well as activities aimed at developing and practising intercultural skills. As the results show, they include different cultural information and focus on developing different skills. Moreover, they mostly present such information implicitly rather than explicitly, for example, model business letters show how business correspondence is written in the target language culture, without making explicit statements on politeness in that culture. It is thus the teacher’s role to select the textbooks, draw the learners’ attention to the cultural elements, and to supplement the books with other materials.

Pedagogical literature identifies established links between student engagement with learning and subsequent academic attainment. During my first year as a GTA, the main challenge I experienced was getting students to verbally engage in seminars, both with myself and their peers. I was surprised by how challenging I found teaching a seminar with limited verbal engagement, and how difficult it was encouraging this during seminar discussions. In this piece, I critically reflect on my experiences as an introverted GTA trying to ‘tackle the tumbleweed’. To commence, I consider the preconceptions I had about what constituted an ‘engaged’ seminar group, and examine varied definitions of (verbal and non-verbal) ‘student engagement’ within the seminar context. Then, I reflect on the techniques I used to encourage both verbal and non-verbal engagement in practice, plus further approaches I will trial in future teaching. In the concluding section, I provide advice for other GTAs and raise wider, external factors likely impacting engagement that lie beyond GTA control.
Harnessing the power of peer dialogue to support GTAs’ professional development: Two reflective stories
Authors: Zhuo Meifang , Li Yanyan
Published: November 2024

Graduate teaching assistants (GTAs) have played an essential role in supporting teaching and learning in higher education institutions (HEIs) across the globe. Enhancing GTAs’ professional development (PD) is critical for ensuring the quality of higher education. The influence of peers in GTA’s PD has been widely acknowledged (e.g., Bale & Moran, 2020; Dobbins et al., 2021). However, there is limited research on the benefits of peer dialogue, one of the most accessible means of harnessing peer powers in GTAs’ PD. This qualitative study aims to explore how peer dialogue can contribute to GTAs’ PD. This study will use data from two narratives detailing the experiences of peer dialogue, completed independently by two senior GTAs in a UK-based university, who are also the first and second authors of this study. Through thematic analysis, the two researchers will first identify the themes of the data separately and then work together to synthesize the key themes from the data, to uncover the key benefits of peer dialogue in promoting GTAs’ PD. The findings of this study will add to the literature on the power of peers in GTAs’ PD and provide insights into the positive impacts of engaging in peer dialogue activities to promote GTAs’ PD. This study will have significant implications for GTAs interested in seeking PD opportunities and for stakeholders who support GTAs in higher education. By highlighting the benefits of peer dialogue, this study also underscores the need to create a supportive environment or platform for GTAs to be engaged in open and collaborative peer dialogue.
Workers, Workplaces, Sorting, and Wage Dispersion in Mexico
Authors: Pérez Pérez Jorge , Nuño-Ledesma José G.
Published: November 2024

Between 2004 and 2018, the spread of wages in Mexico’s private labor sector remained stable. Nonetheless, the underlying factors behind salary dispersion underwent significant shifts nationally and regionally. We analyze a matched employer-employee dataset comprising the near-universe of Mexico’s formal workforce. We estimate log wage models with worker and workplace fixed effects capturing over 94% of wage variation. We then decompose national and regional earnings dispersions into worker, workplace and assortative matching components. At the national level, we find that sorting increased its importance over time, from explaining 16% of total wage variance to 19% by the end of the period. Worker- and workplace-specific factors contributed between 37% to 44% and 33% to 37% to the total spread of remunerations, respectively. Workplace factors became increasingly important during the 2014–2018 time segment, to the point that their contribution to total wage variance is equivalent to that of worker factors. The influence of workplace factors on wage dispersion correlates negatively with regional economic development: It is lowest in the North, Mexico’s most-developed region, and largest in the South, the country’s least-prosperous region.

Foreign experience in researching the problem оf post-traumatic personal growth
Authors: Safin Olexander , Teptyuk Yulia
Published: November 2024

The results of the theoretical analysis of the phenomenon of post-traumatic personal growth are presented: the concept of post-traumatic personal growth is defined, theories explaining the mechanisms of growth are analysed, and predictors of this phenomenon are identified. It is established that post-traumatic personal growth is understood as a subjective experience of positive psychological change after exposure to a life-threatening stressor.
The positive changes described by people experiencing post-traumatic personal growth are represented by the following factors: attitude towards others; new opportunities; personal strength; spiritual changes; and increased value of life. Two main theories of post-traumatic personal growth are described. It is concluded that the perceptions remain one-sided, since these theories consider exclusively cognitive processes occurring after trauma as a trigger for post-traumatic personal growth. At the same time, the analysis of published data has shown that socio-demographic characteristics, health indicators, individual psychological characteristics, predictors related to the traumatic event should also be considered as predictors of post-traumatic personal growth, and the central place should be given to cognitive processes and structures that allow assessing the event in an individual aspect not only as a threat, but also as a source of growth. It has been established that indicators of post-traumatic personal growth are associated with both general and specific factors for different types of trauma. The data on the relationship between severe posttraumatic stress and growth are also of great importance. It was found that post-traumatic stress and post-traumatic personal growth coexist in one person, and it is believed that severe stress is a predictor of growth at distant stages of trauma, and not vice versa.
Diagnosis of post-traumatic stress disorder (PTSD) in military personnel/veterans
Authors: Shelenkova Nataliia
Published: November 2024

Military personnel and veterans often suffer from a psychogenic disorder called post-traumatic stress disorder (PTSD), which has negative consequences for mental and somatic health, social interaction, and overall quality of life.
 It has been found that between 20% and 40% of military personnel need psychological assistance. Symptoms of acute trauma are found in 60-80% of servicemen and women who witnessed the deaths of their comrades or civilians or saw the bodies of the dead. Symptoms of PTSD develop in about 12-20% of servicemen who have sustained combat trauma but have not sought psychological help.
The article outlines the psychosocial factors that cause stress and lead to the development of mental and behavioral disorders and the diagnostic criteria for PTSD (according to DSM-5).  The symptoms of post-traumatic stress disorder in military personnel have been identified.
In accordance with the purpose of the article, the concept of PTSD, the basic principles (safety, interest, minimization of trauma, responsibility, confidentiality, professionalism and professional responsibility, a sufficient minimum, a clear understanding of the limits of professional competence) and criteria for its diagnosis (according to the DSM-5 recommendations) are considered.
The author analyzes the psychodiagnostic tools that can be used for screening and psychological examination of victims of psychotraumatic situations, including military personnel/veterans.
 Examples of screening questionnaires for PTSD aimed at identifying: the main symptoms of PTSD; the type of traumatic event experienced by a person; assessment of the impact of a traumatic event on a person are given.
