В настоящее время нефтяная промышленность сталкивается с насущными проблемами повышения продуктивности скважин, поскольку спрос на нефть растет с каждым днем, особенно в развитых и развивающихся странах. Можно обнаружить, что темпы роста потребления являются серьезной проблемой в текущем контексте. С другой стороны, возможности открытия новых нефтяных месторождений весьма ограничены. Большинство месторождений в настоящее время находятся в зрелом состоянии с низким дебитом. Таким образом, проекты повышения нефтеотдачи (EOR) сильно зависят от текущей экономической ситуации, типа резервной нефти и цен на сырую нефть.

Эта работа представляет собой углубленный обзор состояния иранской экономики, областей ограничений, возможного роста и инвестиций. Это подчеркивает постоянное стремление к поддержанию экономики посредством государственных доходов, создания рабочих мест и валютных резервов в экономике. Цель этой статьи – обсудить необходимость диверсификации экспорта Ирана как страны и снижения зависимости от экспорта сырой нефти и зависимости от импорта других стран для достижения устойчивого экономического роста. Мы использовали методы сравнительного анализа, дедуктивного анализа, а также анализа исторических данных и текущего состояния экономики. Хотя результат показывает, что концепция увеличения прямых иностранных инвестиций, диверсификация экономики и продвижение сильного и конкурентного рынка являются путем вперед для иранской экономики. Ключевым выводом является изучение зависимых переменных, которые можно предсказать, и независимых переменных, которые могут повлиять на зависимые переменные по отношению к экономике, с акцентом на важность открытости торговли, государственных расходов, уровня инфляции и роста ВВП.

The Main Trends in the Development of the Moscow Jazz School (1950s – 1960s)
Authors:   Kosygin State University of Russia, Ovchinnikov Pavel L. , Zaitseva Marina L. ,   Kosygin State University of Russia
Published: November 2023

The present paper deals with the leading trends in the development of Russian jazz art. The authors substantiate high productivity of the “thaw” era in Russian art leading to the emancipation of society, the expansion of the range of cultural communication and formation of the auto-image of Russian jazz. The research explores refraction of jazz aesthetics in stylistics as a youth subculture with its own slang, musical preferences and behavioral models. While the negative consequence of the promotion of jazz as a musical reference point for representatives of this youth subculture was the narrowing and stereotyping of listeners' expectations, the emergence of new artistic types, themes and images that do not lose their significance at the turn of the 21 century came to be the positive side of the popularity of jazz among young people. The paper reveals how Moscow jazz of the 1950s and 1960s entered a period of active development of jazz improvisation techniques, as well as embraced the experience of foreign collectives. Basing on the study of bibliographic sources and musicological literature, the authors identify the leading trends of the Moscow jazz school of the given period: transformation of ensemble interaction strategies, intellectualization of the perception of jazz music, institutionalization of jazz in Russian musical culture. The paper specified socio-cultural factors that determined the leading role of the Moscow jazz school in the period of the 1950s and 1960s in the creation of youth clubs, amateur associations and jazz study centers, jazz festivals, the appearance of the first professional educational institutions of the pop-jazz profile.
The Originality of the Musical Work of the Composer Vladimir Pozhidaev (1946–2009)
Authors:   M. S. Shchepkin Higher Theater School (Institute) under The State Academic Maly Theatre of Russia, Pozhidaeva Galina A.
Published: November 2023

The paper shows the composer's work appeal to serious and significant topics related to the historical and spiritual life of the people of Russia, both in the past and today. Typical artistic images of folk culture and the national nature of the musical language make it possible to qualify the composer’s work as the mainstream of “new folklore wave” of the 50 – 70s of the 20th century through to the 90s and enriching it with folk-instrumental genre. The leading instrumental form in the composer's work becomes a symphony, a concerto - which applies to the principles of genre and epic symphonism. Particular emphasis should be placed on the importance of the spiritual mentality of the Russian people and their musical and liturgical culture The organic fusion of the music of folk life and the high spiritual culture of Holy Rus' allows us to take a fresh look at the composer's work. It brings a new quality to the “new folklore wave”, revealing, along with a genuine folklore stream, a deep Orthodox faith concealed from the official direction of socialist realism, preserved among the people despite all prohibitions and persecution. In the work of V. Pozhidaev, the ancient layers of folk and Christian musical culture are connected in an original way. The depth of the content, the organicity of the folk and professional, expressed by modern means — all this gives rise to a surprisingly original musical world, full of kindness and illuminated by the inner light.
“God’s Roads” of the Russian North: Sacred Hydrography and Hydrosophy of the Northern Pyatirechye
Authors:   N. Laverov Federal Center for Integrated Arctic Research of the Ural Branch of the Russian Academy of Sciences, Terebikhin Nikolay M.
Published: November 2023

The paper displays results of the initial stage of research on the creation of a thesaurus of key geocultural concepts, images and symbols of the Russian North and the Russian Arctic as a cultural code and symbolic resource of spatial development of the Northern macroregion. The research methodology is based on semiotic analysis and hermeneutics of texts of the traditional culture of the region’ peoples, as well as works included in the Northern supertext of Russian literature. The “Island-archipelago” prasymbol and associated image-symbolical ensemble of the sacred hydrosphere (“world river”) are identified as a basic geocultural constant reflecting the structure of physical and metaphysical space (cosmos) of the North and the Arctic. The river network of the North, reproducing the tree-like topology of the “world tree”, acted as a system of spatial, social, and sacred orientations underlying the identity of ethnic and local communities of the region. Sacred hydrography determined the ways and directions of the Slavic-Russian (Novgorod) colonization of the Chud’ north (“Finnish Rus”), colonization models, types and forms of colonists' settlements. In addition to the “island” and “river” symbols, the study provides a semantic analysis of related concepts and images, relevant for building a thesaurus of geocultural symbols of the Russian North and the Russian Arctic (“holiness”, “zemstvo-world”, “Northeast”, “network”, “House of St. Sophia”).

Sovereignty under the Australian Constitution
Authors: Crowe Jonathan
Published: November 2023

Section 6 of the Australia Acts 1986 provides that, when a State law concerns the ‘constitution, powers and procedure’ of the State Parliament, it must abide by any relevant ‘manner and form’ requirements in previous legislation. This provision is generally accepted as imposing a binding limitation on the sovereignty of State Parliaments. However, the reason why this section is binding on State Parliaments is disputed. This article begins by discussing the concept of sovereignty in philosophical terms, before turning to the history of sovereignty in Australia. It explores the role of the Australia Acts in the constitutional system, focusing on their implications for constitutive power in the States, then looks specifically at s 6 and its capacity to bind State Parliaments. I argue that attempts to explain the authority of s 6 by appealing to the United Kingdom or Commonwealth Australia Acts fail. The only satisfactory explanation appeals to the idea that the Australian Parliaments acting together have a special form of sovereignty that allows them to make certain kinds of constitutional changes. This conclusion has important implications for how constitutive power is understood in Australia today.
IMPROVING THE STRATEGIES OF THE MARKET PLAYERS USING AN AI-POWERED PRICE FORECAST FOR ELECTRICITY MARKET
Authors: Bâra Adela , Oprea Simona-Vasilica , Ciurea Cristian-Eugen
Published: November 2023

This paper analyses the recent evolution of the electricity price of one of the EastEuropean countries’ Balancing Markets (BM) – Romania, aiming to understand the prices trend and predict them in the current economic and geopolitical context. This is especially important as the electricity producers have to allocate their output between wholesale electricity market, ancillary services markets and BM targeting to maximize value and achieve a sustainable economic development. Therefore, in this paper, we propose an AI-powered electricity price forecast using several types of standout Machine Learning (ML) algorithms such as classifiers and regressors to predict the electricity price on BM. This approach, consisting of two steps, identifies the imbalance sign and significantly enhances the performance of the price forecast. The proposed method offers valuable insights into the market participants’ trading opportunities using two prediction solutions. The first prediction solution consists of averaging the results of five ensemble ML algorithms. The second one consists in weighting the results of the five forecasting ML algorithms using either a linear regression or a decision tree algorithm. Thus, we propose to combine supervised and unsupervised ML algorithms and find the fundamentals for creating optimal bidding strategies for electricity market players.

Published: November 2023

The mammal community of the Coastal Range of southern Chile has been little studied even though they inhabit an environment under severe threats due to anthropic disturbance. During the spring-summer seasons of 2020–2021 and 2021–2022, we characterized the communities of wild terrestrial mammals in a native forest (NF) and an exotic plantation of Eucalyptus (PL) of the Coastal Range of Osorno province by phototrapping. We used 1,060 camera-trap days in the NF and 960 camera-trap days in the PL to explore the effect of habitat type on wild mammal diversity in two localities (L-1 and L-2). We quantified the species richness, abundance, community similarity and daily distribution of mammal communities. Species richness was higher in the NF (7–8 spp) than in the PL (3–4 spp). Two community similarity index (CSI) was significantly higher between native forests (CSI = 0.728 ± 0.088) than between Eucalyptus plantations (CSI = 0.211 ± 0.097) (95% CI). Mean abundance was also higher in the NF than in the PL (L-1: 0.011 vs. 0.004 occurrence/camera-trap day (OCT); L-2: 0.008 vs. 0.004 OCT). In L-1, the most abundant mammals in the NF were Leopardus guigna (45.3% of relative occurrence (RO)) and Pudu puda (18.9% RO), and in the PL, they were Lycalopex culpaeus (50% RO) and L. guigna (37.5% RO). In L-2, the highest abundances in the NF were for P. puda (34.5% RO) and Puma concolor (27.6% RO), while in the PL, P. puda was predominant (66.7% RO). In NF of both localities, 22.2% of melanic L. guigna individuals were observed. The highest frequency of occurrences in both locations was between 12:00 and 23:59 hours, with 60% and 76.9% of detections, respectively. The species richness found in native forest is in accordance with studies carried out in other temperate rainforests of southern Chile. In addition, native forests support a richer and more similar community of terrestrial mammals than exotic forest plantations, which indicates that native forests are the main habitat for most mammals detected and that exotic plantations function as a complementary habitat for some species.
Taxonomic revision of the Erigeron acris group (Asteraceae) in Murmansk Region, Russia, reveals a complex pattern of native and alien taxa
Authors: Sennikov Alexander N. , Kozhin Mikhail N.
Published: November 2023

Based on the evidence of morphology and a comprehensive revision of herbarium collections and field records, the taxonomy of the Erigeron acris group in Murmansk Region, European Russia, is completely revised. Its accepted diversity is increased from 2 to 8 taxa, including putative hybrids. The only native species, E. politus, is distributed in mountainous regions, along sea coasts and in the Kutsa River basin. Five species are alien: E. rigidus (previously confused with E. acris s.str.), E. acris s.str. (first recorded in the narrow taxonomic definition), E. brachycephalus (previously unrecorded), E. droebachiensis and E. uralensis (previously reported in error). Two major waves of the introduction of alien taxa are discovered, with different occurrences and species compositions. Regional and local dispersal by pomors (historical Russian settlers) occurred during their colonisation and traditional activities since the 12th century (archaeophytes or early neophytes); such alien taxa (E. rigidus, E. brachycephalus, and partly E. acris) are particularly common within the territory traditionally settled by Russian colonists but also found elsewhere along historical trade routes. Other alien species of the E. acris group (E. droebachiensis, E. uralensis, and partly E. acris and E. brachycephalus) colonised industrial areas in the 1960s–1990s as seed contaminants introduced during revegetation of slag dumps, stockyards, dams and channels. Putative hybrids between E. politus (native), E. rigidus and E. acris (aliens) are found in the places of co-occurrence. Updated nomenclature, synonymy and descriptions are provided for all accepted taxa.
Asymmetric volatility spillover between oil prices and regional renewable energy stock markets: A time-varying parameter vector autoregressive-based connectedness approach
Authors: Alharbey Mohammed , Alfahaid Turki Mohammed , Ben-Salha Ousama
Published: November 2023

The rapid expansion of renewable energy sources and their integration into the energy mix has generated scholarly interest in comprehending the interplay between renewable and conventional energy markets. This research aims to examine the (a)symmetric volatility spillover between the oil market and various regional renewable energy stock markets, namely the US, Europe and Asia. To achieve this objective, we employ the time-varying parameter vector autoregressive-based connectedness (TVP-VAR) approach, which allows analysing the interconnection and transmission of shocks between the different markets. Based on an analysis of daily data relative to the different regional renewable energy stock markets and international oil prices, the findings suggest the presence of a dynamic volatility connectedness between the green and brown energy stock markets. The extent of connectedness is contingent upon the specific regional renewable energy market under consideration. Moreover, the decomposition of the volatility series into good and bad volatility emphasizes an asymmetric pattern, which becomes more pronounced during periods of major events. On average, the oil market and the Asian renewable energy stock market are net receivers of volatility shocks. In contrast, the US and European renewable energy stock markets are net transmitters of shocks. Our findings provide investors with valuable insights for portfolio design and risk management decisions.

Published: November 2023

Workers in the trades sectors often experience mental health issues and decreased work ability due to occupational stress, workplace hazards and living in danger or constant fear of injury. Understanding the impacts of psychosocial risk factors on construction workers' mental health can aid in decreasing workplace injuries, lessening disabilities and increasing worker productivity. In this study, we focus on understanding and assessing the mental health and wellness of individuals in the electrical sector that are members of the Employer Engagement Project (EEP) from the Ontario Electrical League (OEL). The subset of potential participants included electricians and plumbers in Ontario working for small to medium sized employers (SME). The recruitment took place in 2022, with a total of 82 participants who completed a survey collecting demographic information, assessing the importance and availability/satisfaction of workplace factors and stress-and burnout-related questions. The data were analyzed using IBM SPSS Statistics 29.0. Two-sample Mann-Whitney U tests were performed to test for associations between the availability of work-related factors and burnout scores among the participants. Burnout scores were determined using the Copenhagen Burnout Inventory. Our findings demonstrate that dissatisfaction of the following factors: Workload allocation, internal staff development opportunity and stable staffing/minimal turnover, were associated with high burnout levels. The findings indicate there may be a relationship between certain work-related factors and burnout levels experienced. There is a need for improvement of workload allocation in SMEs to help enhance the mental health and well-being of employees.

Published: November 2023

Electrical discharge machining (EDM) is mainly utilized for the die manufacturing and also used to machine the hard materials. Pure Copper, Copper based alloys, brass, graphite, steel are the conventional electrode materials for EDM process. While machining with the conventional electrode materials, tool wear becomes the main bottleneck which led to increased machining cost. In the present work, the composite tool tip comprises 80% Copper and 20% silicon carbide was used for the machining of hardened D2 steel. The powder metallurgy route was used to fabricate the composite tool tip. Electrode wear rate and surface roughness were assessed with respect to the different process parameters like input current, gap voltage, pulse on time, pulse off time and dielectric flushing pressure. During the analysis it was found that Input current (I p ), Pulse on time (T on ) and Pulse off time (T off ) were the significant parameters which were affecting the tool wear rate (TWR) while the I p , T on and flushing pressure affected more the surface roughness (SR). SEM micrograph reveals that increase in I p leads to increase in the wear rate of the tool. The data obtained from experiments were used to develop machine learning based surrogate models. Three machine learning (ML) models are random forest, polynomial regression and gradient boosted tree. The predictive capability of ML based surrogate models was assessed by contrasting the R 2 and mean square error (MSE) of prediction of responses. The best surrogate model was used to develop a complex objective function for use in firefly algorithm-based optimization of input machining parameters for minimization of the output responses.

Published: November 2023

Augmented reality technology has been widely adopted in various fields, particularly in the realm of education. In the west, this technology has been applied to various foreign languages such as Malay, English, Chinese, Spanish, French, and Ukrainian. However, in the context of learning Arabic in Malaysia, the use of this technology has been less explored, particularly from the perspective of students at the public university level. Hence, this study aims to examine the level of perception among students at University Sains Islam Malaysia (USIM) regarding the use of augmented reality as a new technology in Arabic language learning today. A questionnaire was used in this study to collect data from a sample of 30 respondents. Analytical findings on frequency distribution, percentage, mean, and standard deviation were obtained through descriptive statistical analysis. Cronbach’s alpha analysis showed that all eight items of the questionnaire had good internal consistency. The overall mean score of the items was 4.48, indicating a high level of data interpretation. Based on the analysis of the findings, the study revealed that the majority of students responded positively and expressed satisfaction with their readiness to use augmented reality in language learning. In conclusion, augmented reality is a valuable learning aid that can greatly benefit students in understanding Arabic vocabulary more easily.

Published: November 2023

The resilience and reliability of healthcare supply chain models were put to the test by the Corona Virus Disease 2019 (COVID-19). This study investigated the application of supply chain systems in South African healthcare institutions during the COVID-19 pandemic. A systematic literature review (SLR) was employed to explore the performance of existing supply chain systems, followed by a case study that tested and compared the acquisition and distribution of COVID-19 resources. The SLR revealed that most of the flare-ups were exacerbated by the acquisition of insufficient resources and speculative shortages as the supply chain systems got overwhelmed by the unprecedented demand. The simulation of the real-world data of South Africa revealed gaps in the distribution of resources, allocation of medical staff to administer COVID-19 vaccines, and shortages of vaccines. The study recommends development of effective contextual (SA) healthcare supply chain systems to support the containment of pandemic flare-ups. The study was conducted in South Africa and only reported data was used.

Published: November 2023

The occurrence of the Covid-19 pandemic during the spring 2020 semester required the face-to-face first accounting course for the first half of the semester to convert purely online for the second half of the semester, creating a version of a blended teaching method. There has been scarce research conducted on blended teaching in the first accounting course in higher education. This research question asked if the blended teaching method created during the Covid-19 Pandemic could resurrect the first accounting course from the results of a student survey and focus group. The results suggested that implementing the blended teaching method in the first accounting course may not only improve the efficiency and effectiveness for the university and the instructor, but most importantly, the satisfaction of the 21st century student resulting in the resurrection of the first accounting course.

Published: November 2023

This study evaluates the merits and challenges associated with onsite and online internships, focusing on their impact on objective achievement, intern-industry interaction, interdisciplinary learning, and globalization through the four-I's framework: intentional, interconnected, interdisciplinary, and international. By comparing the experiences of 21 students engaged in eight-week onsite programs alongside 21 online interns, the study finds that online internships offer flexibility and global accessibility, enhancing international skills. However, they score lower in intentionality, interactivity, and interdisciplinary learning. In contrast, onsite internships excel in providing hands-on experiences, real-time observation, teamwork, and the development of interdisciplinary skills development, albeit underutilizing international dimensions. Future investigations could explore how technological advancements like augmented reality and virtual reality might enhance online internships. Additionally, it could examine how digital tools and social media platforms could facilitate interaction among online interns, mentors, and host companies within the evolving internship landscape.

Authors: Jaffri Abbis , Baellow Andrea
Published: November 2023

Context

Patellofemoral pain (PFP) is a common source of knee pain in active individuals, accounting for a large number of knee injuries examined in sports medicine clinics. As a chronic condition, PFP can affect mental health. However, this effect has not yet been studied in individuals with PFP.

Objective

To determine how subjective physical and mental health measures in individuals with PFP differed from those measures in pain-free individuals.

Design

Case-control study.

Setting

Laboratory.

Patients or Other Participants

Volunteers for the study were 30 people with PFP (19 women, 11 men; age = 20.23 ± 3.32 years, height = 166.69 ± 6.41 cm, mass = 69.55 ± 13.15 kg) and 30 matched pain-free individuals (19 women, 11 men; age = 20.33 ± 3.37 years, height = 169.31 ± 9.30 cm, mass = 64.02 ± 11.00 kg).

Main Outcome Measure(s)

Current and worst pain levels in the past 24 hours were determined using a visual analog scale (VAS). The Anterior Knee Pain Scale, Fear Avoidance Belief Questionnaire, and Lower Extremity Functional Scale were administered. Physical and mental health measures were obtained using a modified 12-item Short Form Health Survey. Scores for 2 subscales on the modified Short Form-12 were weighted and calculated: physical component and mental component.

Independent t tests were calculated to compare variables between groups. Coefficient correlations were used to measure the associations between the variables.

Results

Individuals with PFP reported lower levels of physical (pain free: 56.13 ± 1.63, PFP: 50.54 ± 7.10, P < .001) and mental (pain-free: 53.32 ± 4.71, PFP: 48.64 ± 10.53, P = .03) health. In the PFP group, we found moderate negative correlations between the VAS score for current pain and mental health (r = −0.52, P < .01) and between the VAS score for worst pain in the past 24 hours and mental health (r = −0.46, P = .01) and between activity limitations in individuals with PFP and fear avoidance beliefs (r = −0.61, P < .01).

Conclusions

Our results should encourage clinicians, especially musculoskeletal rehabilitation professionals, to acknowledge the importance of a whole-person approach when treating or planning rehabilitation programs for individuals with PFP.

On the Whitehead nightmare and some related topics
Authors: Poénaru Valentin
Published: November 2023

In this very fast survey I will start by reviewing my work on the QSF property in geometric group theory. While working on this topic, I met some infinitistic complications which I called the Whitehead nightmare. This has analogues in other areas of low-dimensional topology. Afterwards I will present some joint work in progress with Louis Funar and Daniele Otera, where we plan to show that all groups, and only finitely presented groups are concerned by this paper, can avoid the nightmare in question. And also that all groups have the GSC (geometric simple connectivity) property, much stronger than QSF. Both QSF and GSC are explained in the main text.
Glutamine addiction and therapeutic strategies in pancreatic cancer
Authors: Ren Lin-Lin , Mao Tao , Meng Pin , Zhang Li , Wei Hong-Yun , Tian Zi-Bin
Published: November 2023

Pancreatic cancer remains one of the most lethal diseases worldwide owing to its late diagnosis, early metastasis, and poor prognosis. Because current therapeutic options are limited, there is an urgent need to investigate novel targeted treatment strategies. Pancreatic cancer faces significant metabolic challenges, principally hypoxia and nutrient deprivation, due to specific microenvironmental constraints, including an extensive desmoplastic stromal reaction. Pancreatic cancer cells have been shown to rewire their metabolism and energy production networks to support rapid survival and proliferation. Increased glucose uptake and glycolytic pathway activity during this process have been extensively described. However, growing evidence suggests that pancreatic cancer cells are glutamine addicted. As a nitrogen source, glutamine directly (or indirectly via glutamate conversion) contributes to many anabolic processes in pancreatic cancer, including amino acids, nucleobases, and hexosamine biosynthesis. It also plays an important role in redox homeostasis, and when converted to α-ketoglutarate, glutamine serves as an energy and anaplerotic carbon source, replenishing the tricarboxylic acid cycle intermediates. The present study aims to provide a comprehensive overview of glutamine metabolic reprogramming in pancreatic cancer, focusing on potential therapeutic approaches targeting glutamine metabolism in pancreatic cancer.
