A Critical Textual Analysis of Immigration Echoes in Moroccan Football Ultras Discourse
Authors: EL Hadifi Mohammed
Published: November 2024

This study seeks to critically analyze the discursive construction of immigration issue within Moroccan football ultras discourse. Through a critical textual analysis as adopted by Norman Fairclough in his three-dimensional approach, the study analyses the seven chosen chants of Moroccan ultras by analyzing the two meta-functions which are posited by Halliday in his SFL which are integrated by Fairclough in the first stage of his model. This study adopts a qualitative approach, concentrating on the experiential, relational, and expressive values of the lexico-grammatical features present in ultras discourse related to immigration. The findings proved that Moroccan football ultras employ a diverse and ideologically charged lexicon. They employ linguistic techniques such as rewording, over-wording, synonymy, hyponymy, and antonymy to articulate immigration complexities. The use of euphemism, dysphemism, and varying formalities enhances emotional engagement. Their deliberate grammatical choices, following Halliday’s transitivity system, convey agency and immigration experiences while avoiding nominalization and negative sentences. Instead, they use direct constructs and positive framing to highlight immigration drivers. Also, the ultras’ discourse reflects multifaceted relational values and asserts their agency within power relations, aligning with Fairclough’s notion of expressive values to engage emotionally and advocate for change in Morocco. The significance of this study resides in its potential to inform policymakers about the critical need to understand the concerns and preoccupations of Moroccan youth, particularly regarding immigration. Thus, policymakers can work more effectively to address and mitigate the underlying causes of this complex phenomenon.
Critical Discourse Analysis of Artificial Intelligence in Gates' Social Media Content
Authors: Alashtary Tabarek
Published: November 2024

Artificial intelligence (henceforth, AI) is one of the most remarkable topics on social media platforms. The current study aims to investigate the representation of AI in Bill Gates’ social media content to uncover the hidden ideology of one of the most influential figures in the field of AI technology. Furthermore, critical discourse analysis (henceforth, CDA) examines the relationship between language, ideology, and power in various social and cultural contexts. The study aims to answer the following questions: 1- What are the lexical devices that are used to represent Artificial Intelligence (henceforth, AI) in Gates' social media content to construct the "self "and the "other"? 2- How is intertextaulity utilized in social media in terms of ideology and the construction of "self" and "other"?
The researcher forms an eclectic model of CDA using Fairclough’s (2001) three-dimensional model and Van Dijk’s (1995) ideological square model. Based on the findings, the study concludes that the examination of lexical devices reveals the way the "self" represents his AI technology and its benefits to the world. While the representation of "other" is illustrated in the environment that surrounds AI technology.
Modelling The Role of Institutional Change In A Tourism Growth Model: A Dynamic Analysis
Authors: Wada Isah
Published: November 2024

This study aims to investigate the dynamic relationships among foreign direct investment (FDI), financial development, tourism development, and institutional quality in selected MENA countries. The research focuses on assessing the significance of institutional quality within these interlinked dynamics and its impact on the variables under consideration. The study's objective aligns with UNSDG Goal 16, which aims to promote peaceful and inclusive societies with strong institutions that support economic growth and development. The study employs a novel panel Autoregressive Distributed Lag (ARDL) estimation approach to analyze empirical data from 2002 to 2018. This method allows for a comprehensive examination of both short-run and long-run interactions among FDI inflows, financial development, tourism development, and institutional quality across multiple countries in the MENA region. The empirical results indicate that, in the long run, institutional quality negatively influences FDI inflows, financial development, and international tourist arrivals, while it positively impacts real GDP. In the short run, financial development was found to negatively affect real GDP, and international tourist arrivals were observed to negatively impact financial development. Additionally, institutional quality exhibited a negative effect on international tourist arrivals in the short run. Country-wise regression results showed that institutional quality positively influenced international tourist arrivals, FDI inflows, real GDP, and financial development. Furthermore, the study identifies significant unidirectional causal relationships, highlighting the pivotal role of institutional quality in economic growth and development. The study concludes that institutional quality plays a critical role in shaping the dynamics of FDI, financial development, and tourism growth. While institutional quality has a positive impact on long-term economic growth, its negative effects on FDI, financial development, and tourism in the short run suggest the need for improved governance and policy interventions.
Winter is Coming: A Tale of Two Futures – Entrepreneurial State or Creative Destruction?
Authors: Morales-Alonso Gustavo
Published: November 2024

This paper aims to explore the fundamental principles of sound monetary policy, fiscal prudence, and entrepreneurial innovation, which have historically supported the economic prosperity of nations. It seeks to identify the factors leading to an impending financial crisis and proposes countermeasures based on market liberalization and individual entrepreneurial resilience. Using a critical analysis of prevailing economic conditions, this paper evaluates the unchecked expansion of the monetary supply, fiscal policies, and government interventions. The methodology includes a review of historical economic trends and the application of theoretical frameworks concerning monetary policy, fiscal responsibility, and market innovation. The research identifies that the unchecked expansion of the monetary supply has contributed to inflationary pressures, diminished savings incentives, and led to the misallocation of capital. In addition, fiscal looseness and increased government intervention have exacerbated these economic vulnerabilities, creating conditions ripe for an economic crisis of substantial magnitude, possibly surpassing previous crises such as the Great Recession and the COVID-19 pandemic. The paper concludes that this impending crisis is not an unforeseeable "black swan" event but rather one with clear warning signs that require immediate action. The findings advocate for a departure from interventionist policies and emphasize the importance of returning to foundational economic principles, including market liberalization and fostering individual creativity and entrepreneurial innovation. This paper serves as a timely call for policymakers to address these challenges before the full impact of the crisis is realized.
ESG and Administrative Costs in Equity Trading: Evidence from China
Authors: Huang Lanchun , Wang Zhan
Published: November 2024

Recent findings suggest that firms with higher Environmental, social, and governance (ESG) scores may experience lower stock returns, contrary to the common belief that better ESG performance enhances market reputation and stock returns. This study aims to investigate the relationship between ESG performance, management costs, and stock returns by introducing an "ESG-cost framework." The framework proposes that the costs incurred in implementing ESG practices can reduce revenue, offsetting the positive effects of strong ESG performance. Using an empirical analysis of firms based on both their ESG scores and management costs, the study finds that firms with low management costs gain the most from high ESG scores, while those with high costs may see diminished stock returns despite strong ESG performance. Additionally, the study proposes trading strategies that integrate ESG scores and cost considerations, demonstrating that these strategies yield better returns than traditional market indices. These findings offer a new perspective on ESG decision-making and provide valuable insights for constructing effective trading strategies.
Challenges of ICT Integration in Social Work Practicums in African Higher Education: A Systematic Review
Authors: Rammutla Mmathato Calphurnia
Published: November 2024

This systematic review explores the role of Information and Communication Technology (ICT) in enhancing social work practicums within higher learning institutions across developing African nations. Key challenges identified include the absence of clear institutional policies for ICT integration, insufficient funding for welfare organizations, particularly from the South African Department of Social Development, and unreliable internet access in rural regions. Additionally, the lack of clarity within the Department of Education’s policy framework regarding appropriate technologies for educational curricula hinders students’ practical experiences. Using the PRISMA methodology, this review analyzed 65 peer-reviewed articles selected from an initial retrieval of 320 sources from databases such as Google Scholar, Taylor & Francis, Scopus, ScienceDirect, and ResearchGate. The inclusion and exclusion criteria ensured relevance to the topic of ICT challenges in social work education. The findings highlight a pressing need for revised policies and the introduction of new legislation to address the technological barriers that limit social work students’ access to essential resources like Wi-Fi, digital infrastructure, and institutional support. These challenges are particularly acute in South Africa, Zimbabwe, and Mozambique, where limited technological infrastructure and financial constraints impede progress. Nonetheless, the development of Continuing Professional Development (CPD) guidelines, the introduction of affordable technologies, and the establishment of a robust national policy framework for ICT integration can significantly improve the quality of social work practicums, facilitating better alignment between theory and practice.

Authors: Motaung Mamello , Roberts Hester , Makhoahle Pakiso
Published: November 2024

Many Southern African countries, including Lesotho, face severe health and environmental issues attributed to waste disposal. The purpose of this study is to assessed the environmental and health impacts on residents living in proximity to disposal sites in the lowlands of Lesotho. A descriptive cross-sectional design was employed, using a semi-structured questionnaire and observation method. A mapping device was used, and photographs were taken to validate the findings. Descriptive statistics and the Chi-square test (?²) were employed to analyze the data. Results indicate that in Lesotho, some landfill sites are located as close as 50 meters from residential areas, and most (60%) received hazardous mixed waste streams. Waste burning and backyard dumping were the most frequently used disposal methods by residents. Several perceived health outcomes and environmental issues were noted, with respiratory and gastrointestinal health issues being the most prevalent. There was a statistically significant association between waste burning and respiratory diseases (P < 0.010) and between backyard dumping and gastrointestinal diseases (P < 0.003). The study concludes that regulatory instruments need to be revised and enforced, requiring hazardous waste producers to take responsibility for end-of-life waste and banning the entry of such waste into disposal sites. The application of waste management strategies to initiate other preferable end-of-life waste procedures, such as recycling of WEEE and waste-to-energy technologies for organic waste in Lesotho, could improve the quality of health for residents and their environment.
Indigenous language preservation: A study of the Tshivenḓa speech community in South Africa
Authors: Mudau Phethani Progress , Mandende Itani Peter , Mushaathoni Maria
Published: November 2024

This sociolinguistic study explored the significance of language preservation through the use of indigenous forms of address by the Vhavenḓa in South Africa. Indigenous forms of address are integral to the language and cultural identity of a society. Furthermore, they are indispensable in the preservation of the language and culture of any society. Ignoring the use of these forms of address can lead to language shift or even extinction. This study utilised face-to-face semi-structured interviews to gather and analyse data. The researchers sampled 22 Tshivenḓa L1 participants, 14 youths, and eight elders. The study used the ethnopragmatic theory as its framework. This theory helped the researchers to understand the use of forms of address within the Tshivenḓa cultural scripts, such as cultural norms and values. The findings revealed that using forms of address is pivotal in preserving the Tshivenḓa language. The language will be preserved if lexical items, such as aa, nndaa, and mboloma, are used for greeting. The Vhavenḓa speech community is found in the Limpopo Province in South Africa; the term “Vhavenḓa” refers to people who speak Tshivenḓa, while Tshivenḓa refers to the language and culture of these people. The study recommends that Indigenous Tshivenḓa forms of address should be included in school syllabuses and aired on television and radio programmes. In this way, the Tshivenḓa language can be prevented from shifting or dying, as its disappearance may have dire consequences for its development as a language.

Authors: CHI Bing , Gao Xiang
Published: November 2024

China has emerged as Indonesia's largest trading partner, creating new opportunities for bilateral economic cooperation. However, challenges related to cultural differences in joint ventures have become increasingly important. Improving cross-cultural adaptability and joint venture performance is crucial to strengthen collaboration and exchange. This study aims to explain the theory of cross-cultural adaptation in joint ventures, establishing connections between employee backgrounds, cross-cultural activities, support, and networks to develop new theoretical foundations for promoting such adaptation. The study examines the dynamic impact of cross-cultural adaptation on business performance by analyzing data from 30 China-Indonesia joint ventures between 2008 and 2019. The results indicate that cross-cultural adaptation comprises four components: employee backgrounds, cross-cultural spending, support, and networks. Notably, as cross-cultural adaptability improves, joint venture performance increases significantly. Among these components, cross-cultural networks have the most substantial impact on performance. These findings suggest joint ventures should enhance cross-cultural resilience through targeted activities to improve performance.

Authors: Abusalam Mukhtarov Abusalam Mukhtarov
Published: November 2024

Azerbaijan, traditionally known for its vast oil and gas reserves, also harbors considerable geothermal energy potential that remains largely untapped. This paper delves into the geothermal resources of Azerbaijan, assessing their viability for both electricity generation and direct applications such as heating. According to the State Agency on Alternative and Renewable Energy Sources (SAARES), the country’s geothermal energy potential could reach up to 800 MW. The thermal waters in the territory of the Azerbaijan Republic span across 11 geothermal zones, with temperatures ranging from 30°C to 100°C, allowing for diverse energy applications. Key geothermal regions include Kelbadjar, Ilisu, and Bagirsag, where springs like Shikhovo and Ibadisu exhibit water temperatures between 36°C and 95°C. Additionally, balneotherapeutic springs, including IstiSu and Darydag, offer further opportunities for geothermal exploitation. The study also reviews significant geothermal wells in Jarly-3, Khachmaz, Yalama, and Nakhchivan Daridagh, where temperatures range from 26.5°C to 96°C, with corresponding flow rates and potential power outputs varying widely. For instance, the Jarly-3 well has a flow rate of 2000 m³/day at 92°C, capable of generating approximately 70 MW if cooled to 20°C. These findings highlight the abundant geothermal resources across Azerbaijan and underscore the strategic importance of developing these resources to diversify the country’s energy portfolio, enhance energy security, and promote environmental sustainability. This paper provides a comprehensive analysis of Azerbaijan’s geothermal potential and recommends approaches for its effective utilization to meet future energy needs.

STUDY OF CONDITIONING EFFECT OF BALL VALVES
Authors: Leyla Ibayeva Leyla Ibayeva
Published: November 2024

Two or more configurations are combined to provide common use of ball valves. The use of metal fasteners in ball valves is used to ensure tightness under conditions of high temperature and pressure. Studies conducted on connecting structures show that 70% of them fail due to problems of fixation. With the application of a magnetic device, the position of the connectors is different in the open and closed state of the faucet. In the open state of the faucet, the magnetic force does not affect the connectors. This, in turn, minimizes the friction that may arise in the coupling elements in the ball-coupling pair. The correct design of fastening systems is an important factor for efficient and reliable operation. Methodologies range from simple computation-based procedures to detailed mathematical models. An appropriate mathematical model for the design and analysis of a crane provides a logical equivalent determined by the characteristics of the system. The design methodology offers a number of innovations for the identification of all possible system configurations capable of meeting a specific requirement according to the required levels of reliability.

REMOVING RESIDUAL OIL BY INJECTING A SOLUTION-AIR COMPOSITION THROUGH A NEW INJECTOR INTO THE WETTED FORM
Authors: Azer Gasimli, Elshan Aliyev Azer Gasimli, Elshan Aliyev
Published: November 2024

In the literature, the physical mechanism of the method of increasing the oil yield of the formation by means of elastic waves is indicated by various terms: vibrating, acoustic, elastic, pulsed, seismoacoustic, etc. We will talk about a general term that illuminates them in their physical essence - the method of wave action.
Until now, some industrial-experimental application of the wavy impact method has been carried out in the fields of the former USSR and foreign countries. The wave field is divided into two parts according to the value of the generation frequency - the low-frequency effect of the method (up to 1 kHz) and the high-frequency effect of the method (higher than 1 kHz). The conversion of the first generated energy, the vibrating wave, into elastic energy is divided into mechanical, hydraulic, gas-pneumatic, electromechanical, etc. The use of this and other modifiers is chosen depending on the type of determined method of influence (increasing oil yield, intensification of filtration and reception), the geological and technical condition of the field and individual wells, and most importantly, the expected technical and economic effect.
The wave effect is carried out near the selected area of the formation from the ground surface and the wellhead, using special vibration and impulse sources. The main issue of the acceptance of the wave effect method is the understanding of the physical process of elastic wave radiation in a porous medium saturated with formation fluids.
Abasov MT, Hadiyev SM, Mirzajanzade AX, Krylov AP, Khavkin AY, etc., are the main works of this issue. carried out by the authors, it was possible to reveal the physical meaning of the processes taking place in the layer.
Many modern oil recovery methods, such as the wave effect method, help to reduce the influence of some factors that make oil extraction difficult. However, they do not take into account the fact that they are not applied in time and that natural hydrocarbon fluids move under the influence of gravitational effects and capillary forces, which leads to a decrease in technical and economic indicators.

ANOVA analysis also confirmed that PBL had a significant effect on the enhancement of both skills. These findings demonstrate that the application of PBL in PAI learning significantly improves students' critical and creative thinking skills, making it an effective method to address educational challenges in the modern era

Penelitian ini bertujuan untuk memahami konsep rasionalitas ekonomi Islam yang menekankan keseimbangan antara tujuan materi dan spiritual. Menggunakan metode kajian pustaka dengan menganalisis literatur terkait. Hasil penelitian menunjukkan bahwa rasionalitas ekonomi Islam berfokus pada upaya setiap pelaku ekonomi untuk mencapai mashlahah, menghindari pemborosan, dan meminimalkan risiko dalam situasi ketidakpastian. Selain itu, konsep mashlahah mencakup lima jaminan dasar: keselamatan agama, jiwa, akal, keluarga dan keturunan, serta harta benda. Rasionalitas dalam ekonomi Islam juga mengutamakan etika konsumsi yang sesuai dengan prinsip syariah, seperti menghindari perilaku berlebihan dan lebih memprioritaskan kehidupan akhirat. Keimpulan dari penelitian ini menekankan pentingnya penerapan prinsip-prinsip ekonomi Islam dalam menciptakan keseimbangan antara kepentingan duniawi dan ukhrawi.
This study aims to understand the concept of Islamic economic rationality, which emphasizes the balance between material and spiritual goals. The research uses a literature review method by analyzing relevant sources. The findings show that Islamic economic rationality focuses on the efforts of economic actors to achieve mashlahah, avoid wastefulness, and minimize risks in uncertain situations. Additionally, the concept of mashlahah encompasses five fundamental guarantees: the protection of religion, life, intellect, family and lineage, and wealth. Rationality in Islamic economics also prioritizes ethical consumption in line with Sharia principles, such as avoiding excessive behavior and prioritizing the afterlife over worldly matters. The conclusion of this research highlights the importance of applying Islamic economic principles to create a balance between worldly and spiritual interests.

Objective. To study the features of X-ray manifestations of knee joint arthrosis in women of different ages, depending on bone mineral density and severity of X-ray morphometric signs of osteopenia and osteoporosis of the spinal.

Materials and methods. The study involved 82 women aged 50 to 77 years, divided into three unequal age groups (50–59, 60–69, 70 years and older); to assess the X-ray morphometric signs of osteopenia and osteoporosis, standard radiographs of the thoracic and lumbosacral spine in two projections were used; manifestations of gonarthrosis were assessed by the results of radiography of the knee joints in a direct projection — the index of the knee joint was calculated, and a semi-quantitative assessment of characteristic x-ray changes was made; Quantitative X-ray computed tomography on a Somatom CT (Siemens) of 2, 3, and 4 lumbar vertebrae was used as an absorptiometry technique.

Results. As expected, a decrease in the index of the knee joint index with increasing age was observed. In the oldest age group (over 70 years), with minimal bone mineral density and the most pronounced X-ray manifestations of osteopenia and osteoporosis of the spinal column, there was no significant increase in the prevalence of manifestations of arthrosis of the knee joints in the form of subchondral osteosclerosis and bone growths along the edges of the articular surfaces.

Conclusions. The results of this study establish the relationship between bone mineral density and X-ray manifestations of arthrosis of the knee joints in the form of subchondral osteosclerosis and marginal bone growth.

Relevance. Activation of innate and acquired immunity, accompanied by increased production of classical (interleukin (IL) IL-1β, IL-6, tumor necrosis factor-α (TNF-α) and interferon-γ (INF-γ)) proinflammatory cytokines in synovial fluid and blood serum, plays an important role in the pathogenesis of rheumatoid arthritis (RA).

Objective. To determine the concentration of IL-1β, IL-6, TNF-α and INF-γ in RA patients in the advanced stage of the disease, to evaluate the relationship between them, clinical indices of disease activity, the presence of rheumatoid factor (RF), and antibodies to cyclic citrullinated peptide (ACCP).

Material and methods. We examined 154 patients with RA (41 men and 113) who were middle-aged (56.0 (50.0; 64.0) years), disease duration (9.4 (3.0; 13.0) years), seropositive 129 (83.8 %) for IgM RF and/or 106 (68.8 %) ACCP with moderate to high (DAS28-ESR — 5.40 (4.65; 6.00)) disease activity. The concentration of IL-1β, IL-6, TNF-α and INF-γ in serum determined by multiplex technology.

Results. The concentration of IL-1β was not significantly different between patients with RA and controls. The values of IL-6 and INF-γ were significantly higher, and TNF-α — significantly lower than in donors. IL-6 hyperproduction was detected most frequently (51.6 %), whereas elevated levels of INF-γ (38.96 %), IL-1β (26.62 %) and TNF-α (23.38 %) were less common. Significant positive correlations were observed between the concentrations of all cytokines and their high levels. The strongest correlations were characteristic for IL-1β, TNF-α and INF-γ. No statistically significant differences in cytokine levels were observed between patients with RA who were positive or negative for IgM-RF and ACCP. The concentration of IL-6 alone significantly positively correlated with the values of the indices (DAS28-ESR, CDAI, SDAI) of RA clinical activity (p<0.05).

Conclusions. There are differences in the levels and frequencies of proinflammatory cytokines among patients with advanced-stage RA. In the presence of a close relationship between them, there are certain differences in their associations with clinical and laboratory indicators of disease activity.

Osteoarthritis (OA) of the knee joints (KJ) has a high social significance and is therefore a relevant pathology for scientific research. The authors have proposed an original hydraulic theory for the pathogenesis of OA in KJ. This approach is based on the notion of primary mechanical damage to the internal ligamentous structures and synovial membrane accompanied by posttraumatic edema, synovial hypervolemia, and hypertension. The authors demonstrated that regular physical activity at all stages of the disease is pathogenetically justified and allows the patient to improve lymphatic and venous outflow and thus resist increasing fibrosis. Improved arterial blood flow will reduce tissue hypoxia. Any type of symptom-modifying therapy can be harmful because it reduces the protective role of pain reflexes in protecting the KJ from excessive loads, leading to injury. The necessity of maintaining a walking speed of more than 4.3 km/h with an increase in cadence is emphasized from the perspective of reducing static stress during walking and extending life expectancy.

Rehabilitation is widely recommended in national and international guidelines for the treatment of osteoarthritis (OA) and is considered one of the main treatment strategies for patients with OA. Osteoarthritis rehabilitation includes physical exercise, strength training, weight-control, and self-control training and includes transitioning to an active lifestyle.

A review of the effectiveness and safety of rehabilitation for the treatment of OA was conducted, and international evidence-based recommendations were analyzed. Physical therapy is widely recommended for the treatment of OA. In this review we focused on exercises on land and water, and strength training for OA. In general, evidence indicates that physical therapy and special strengthening exercises or strength training for the lower extremities can reduce pain and improve physical function in knee joint OA. Data from other OA localities are less reliable. Therefore, considering the lack of special studies, recommendations for treating hip and hand OA are based on studies on knee OA. In addition, no recommendations regarding the exercise regime have been developed. The effectiveness and safety of physical therapy and strength training should be further evaluated in randomized controlled trials involving patients with OA of the hip joint and hands. It is also necessary to define the optimal composition of exercise programs more clearly.

A search of relevant literature was conducted in PubMed and the Cochrane Database from 2014 to March 1, 2024. Exclusion criteria: absence of comparison groups; total number of study participants <20 and premature termination of the study.
