The Iron Wall Revisited: Utopian Paradigms in Jabotinsky's Conception of Zionism, Circa 1923
Authors: Horowitz Brian (Yossi)
Published: November 2024

ABSTRACT: Jabotinsky's two Iron Wall essays of 1923–24 offered solutions to all sorts of problems: conflict with the Arabs of Palestine, refocusing Britain's government on attaining the goals in the Balfour Declaration (at least as Jaobtinsky understood them), and energizing the pace of Jewish emigration. Above all, after the violence in 1920 and 1921, Jabotinsky articulated a way to achieve peace. Although the most people perceive the essays as a prediction of the future—only naked violence will work—I believe the essays have their main importance as windows onto Jabotinsky's present and especially on his past, i.e. his political development since the Helsingfors Conference in 1906. This is because Jabotinsky changed, having fashioned himself from a subaltern representative of a small minority in the Russian Empire into a leader of an independent political grouping with specific needs to gain popularity in the present.

Published: November 2024

The growth, from a global perspective, in plastic waste sees its necessary promise in Artificial Intelligence. The driving force of Machine Learning, Computer Vision, and Predictive Analytics, shapes each style of waste management and effective collection routes to recycling. In this paper, therefore, the discussion will be on how AI can ensure a reduction in plastic waste, focusing on developing countries such as Nigeria. The theoretical underpinning of this research is on AI adoption, the Technology Acceptance Model, a few real-world case studies in AI for waste reduction, and many challenges that need to be focused on due to issues of data sparsity, infrastructure limitations, and ethics. Using these challenges for unlocking the full potential of AI in the direction of a more sustainable future, with minimal plastic waste at the forefront of environmental well-being, could be better negotiated. As the global community faces the pressing need to tackle plastic pollution, especially in areas with inadequate waste management systems and severe environmental challenges AI technologies present groundbreaking solutions to improve waste management methods, eliminate environmental harm, and foster sustainable growth. A crucial factor influencing the future of AI-driven plastic waste reduction in developing countries is the ongoing progress and implementation of AI technologies.

Published: November 2024

This study investigates the impact of economic inflation on food security and accessibility through the development of an econometric modeling approach. As inflation rates rise, the purchasing power of consumers diminishes, leading to increased food prices and potentially exacerbating food insecurity. This research aims to quantify the relationship between inflation and food security indicators, such as availability, access, utilization, and stability of food supplies. By employing time-series data and econometric techniques, the model captures the dynamic interactions between inflation rates, food prices, and socioeconomic factors affecting food security. The model incorporates key variables, including consumer price index (CPI), food inflation, income levels, and unemployment rates, to analyze their collective impact on food security across different demographics. The findings indicate that rising inflation significantly correlates with higher food prices, disproportionately affecting low-income households and vulnerable populations. This relationship highlights the necessity of understanding inflation's broader implications on food accessibility, especially in regions where food security is already a pressing issue. Future research directions are proposed, focusing on policy interventions aimed at stabilizing food prices and enhancing food security. Potential strategies include price controls, subsidies for staple foods, and targeted social safety nets for low-income households. Additionally, the study suggests further examination of supply chain factors contributing to food price volatility, such as transportation costs and global market dynamics, which can exacerbate inflation's effects on food security. This research contributes to the literature on food security by providing empirical evidence of inflation's impact on food accessibility and identifying critical areas for policy intervention. By addressing the complex interplay between inflation and food security, stakeholders, including policymakers and food industry leaders, can develop informed strategies to mitigate adverse effects and promote food security in inflationary environments.

The review underscores the potential of digital phenotyping to revolutionize ASD monitoring, enabling more personalized, data-driven approaches in public healthcare systems.
Assessment of cultural resources and their associated practices focusing on agricultural water sustainability in present environmental conditions
Authors: Akash Sharma  , Meenakshi Dhote
Published: November 2024

Cultural resources, recognized as the fourth pillar of sustainable development, are integral to the holistic development of society and place. These resources include art and literature, as well as lifestyles, ways of living, value systems, traditions, and beliefs. Resources and activities directly or indirectly associated with culture have a holistic impact on society. Many of these resources become embedded in our culture, and their regular use contributes to the protection of environmental conditions. This paper discussed various cultural resources and their associated practices. People’s engagement with cultural resources is often reflected in their practices of worshiping nature, which can form the basis for the emergence of a faith-related environmental ethic. Agricultural water sustainability, which is deeply connected to cultural practices, plays a crucial role in maintaining the balance between resource use and environmental preservation. Finding highlighted that sustainable water management in agriculture ensures that the cultural practices linked to these resources are not only preserved but also adapted to contemporary environmental challenges. The study identified issues related to specific resources, which had led to their depletion and the decline of associated practices. The findings suggested that the degradation of environmental conditions is linked to the depletion of cultural resources, a concern that needs to be addressed. By identifying and addressing these issues in advance, we could preserve the resources sustainably for the future.

Authors: Elnaz Ghaffari
Published: November 2024

This case report explores the unique life experiences of an individual diagnosed with both Attention Deficit Hyperactivity Disorder (ADHD) and Asperger Syndrome, highlighting how these two conditions can complement each other. The individual, referred to as Alex, demonstrates how ADHD's impulsivity and hyperactivity can balance Asperger Syndrome's need for routine and predictability, and vice versa. This dual diagnosis presents both challenges and strengths in social interactions, cognitive abilities, and emotional regulation. Alex's case illustrates that the impulsivity and creativity driven by ADHD can be balanced by the structured thinking and focused attention associated with Asperger Syndrome. This interplay creates a dynamic balance that enhances overall functioning and productivity. The report emphasizes the importance of personalized management strategies that leverage the complementary aspects of both conditions, suggesting that understanding these interactions can lead to better support and improved outcomes for individuals with similar diagnoses. The findings of this case report have implications for clinical practice, highlighting the need for tailored therapeutic approaches that consider the unique strengths and challenges presented by coexisting ADHD and Asperger Syndrome.

Authors: Izuchukwu Precious OBANI  , Theresa Ojevwe AKROH
Published: November 2024

This paper evaluated the effectiveness of environmental taxes and adopted a case study approach which used carbon pricing in the UK as a tool to reducing Greenhouse Gases Emissions. The objectives of the research are to determine the effect of carbon pricing on greenhouse gases emissions in the United Kingdom, evaluate how fossil energy depletion affect greenhouse gases emissions in the United Kingdom and ascertain the effect of total energy consumption from different energy mix on greenhouse gases emissions in the United Kingdom. The paper used an ex post facto research design and the estimated model was estimated using the ordinary least squares regression technique. The data were sourced from different sources and covered the period between 2010 and 2023. The findings of the study revealed that carbon pricing is an effective tool for reducing greenhouse gases emissions in the UK while renewable energy is also a significant tool for reducing greenhouse gases emissions. Based on these findings, the study recommends that the government should consider increasing the carbon price incrementally over time to ensure that it continues to effectively discourage high-emission activities.

This study characterized Zambian indigenous chickens' phenotypes and morphometric traits in Kabwe District, Zambia, to create a base for breeding program development. To achieve this, 206 hens and 228 cocks we sampled in Kabwe district. Each sampled chicken was phenotyped for 4 qualitative traits: ear lobe color, shank color, comb type, and eye color. Individual linear body measurements were recorded from each chicken using a tailor's tape in centimeters, which included body length (BL), chest circumference (CC), corpus length (CL), keel length (KL), shank circumference (SC), shank length (SL), thigh circumference (TC), and thigh length (TL). The findings showed that the predominant phenotypes were single comb type (98.91%), orange eyes (80.44%), white shanks (33.70%), and red-white earlobe color (50%). The average body weight was 1698.24 g, which showed a significant positive correlation (p<0.05) with all linear body measurements. For both sexes, body weight correlated positively with all linear measurements, except in males where body length showed a nonsignificant negative correlation. A stepwise regression analysis indicated that chest circumference, keel length, body length, shank circumference, thigh circumference, and corpus length (CL) are significant predictors of body weight (R² = 76.90%, P < 0.05). Additionally, the CHAID data mining algorithm identified keel length as the primary predictor of body weight, with corpus length and thigh length also contributing, achieving an R² of 61.20%. These findings provide valuable insights for instituting chicken breeding programs aimed at enhancing productivity and selection decisions.
A review of the limitation of legitimate expectation principle in FET Claims in energy regulatory disputes: Can a balance be achieved?
Authors: Saheed Abudu SJD
Published: November 2024

This article explores the intricate interplay between the right of states to regulate in the context of environmental regulations aimed at decarbonization and an investor's right to investment protection, particularly focusing on the Fair and Equitable Treatment (FET) standard in international investment law. With the increasing importance of environmental regulations such as the US Greenhouse Gas Standards and Guidelines for Fossil Fuel-Fired Power Plants, in the transition to cleaner energy sources, the potential economic impacts on investments and resulting investment disputes could be huge, making the balancing of these competing interests a topical issue. The article delves into the prominence of the FET standard in investment protection and its evolution in international investment law. It argues that the limitation on the legitimate expectation element of the FET standard in modern times poses challenges in balancing states' rights to regulate with the protection of foreign investments in decarbonization disputes. The author asserts that recent developments in international investment law, exemplified by treaties like the EU-Canada Comprehensive Economic and Trade Agreement (CETA) and the United States-Mexico-Canada Agreement (USMCA), signal a shift towards prioritizing states' right to regulate over investment protection. By analyzing the limitations on legitimate expectation and investment protection in modern times and the implications for energy investments in the era of decarbonization, the article aims to shed light on the complexities of reconciling the competing interests of states and investors in the evolving landscape of international investment law. Ultimately, this author contends that achieving a balance between these interests is increasingly challenging and may require a reevaluation of the prevailing norms in investment protection.

Authors: Uzondu C. Dike  , Victor M. Jackson
Published: November 2024

This paper discusses the possibilities of integrating cloud-based IoT with telemedicine as the ways to advance the healthcare industry performance and change its context for the better. This paper aims at exploring how these technologies can be integrated to enhance the existing solutions to the present problems of health care access, patient interactions and use of analytical data in practices. Possible ways in which IoT devices and cloud technology can enhance patient care and assist clinicians in their process of arriving at diagnoses are problems that the research seeks to uncover. The method used is a qualitative systematic review of prior studies related to telemedicine, IoT, and cloud computing, accompanied by a thematic analysis to reveal emerging patterns and the gaps in the literature examined in the study. The new model ‘‘Telemedicine Integration with Cloud-Based IoT,’’ was categorized thematically by differentiation of real-time severity, data privacy, patient interaction and technological difficulties. This model considers layers for acquiring IoT data, storing and analysis, a healthcare remote interface, a machine learning based analytics, and security, which offer a holistic way to enhance healthcare services. Real-time IoT, cloud-based storage, AI for early diagnosis, secure telemedicine platforms, data protection, and complete os compatibility. Based on this study, the authors posited that the convergence of IoT and cloud is capable of redesigning telemedicine by delivering better quality, efficient, and accessible healthcare solutions. However, they lack socio-economic factors for example, the feasibility cost for implementing it for the health companies and difficulties faced by the patient in the less-developed regions. The main limitation observed in the current research is related to the barriers hindering its implementation and future studies are suggested to address these challenges by exploring improved cost-effective approaches to overcome these and other barriers and analysing the issue of data security and patients’ privacy regulation. Studies should also aim at the long-term implications on the user satisfaction in order to introduce or show the long term positive and negative effects of cloud IoTs in telemedicine.

Authors: Gromova T. A. , Levakov S. A. , Mushkyurova D. R.
Published: November 2024

Due to the high prevalence of cervical cancer, it is necessary to take measures aimed at reducing its frequency through vaccination, screening, detection and treatment of precancerous conditions. The article presents a systematic analysis of scientific data on the use of testing for self-sampling for human papillomavirus as a tool to improve the effectiveness of screening and detection of precancerous diseases of the cervix. It has been shown that the use of such tests, which are based on polymerase chain reaction (PCR), have similar clinical accuracy compared to sampling by a doctor, and thus this option is promising for expanding the coverage of cervical cancer screening. The presence of expected economic efficiency also determines the relevance and prospects for these tests, but further research is needed to assess their implementation in routine practice.

К вопросу о провенансе картины «Перекрещенный белый квадрат (черное с красным)»
Authors: Каменский Михаил
Published: November 2024

В статье представлен первый этап исследования провенанса живописной композиции «Перекрещенный белый квадрат / Черное с красным» (1919?)», холст, масло с предполагаемым авторством К. Малевича, которая находится в частном собрании в Нидерландах. На обороте картины присутствует надпись: «К. Малевич. 1919. Супрематизм духа №11». По своей композиции картина близка работе Малевича «Супрематизм духа» (1920), выполненной на доске, из собрания Фонда Харджиева (музей Стедейлик, Амстердам). К исследованию провенанса произведения из Нидерландов побудили документы Н. Харджиева и письмо Л. Лисицкого. подлинность которых подтверждена экспертизой архивистов и почерковедов. Из них следует, что с начала 1920-х по 1984 год: картина последовательно находилась у Лисицкого, далее в музее Асконы, у А. Веревкина, Н. Харджиева и В. Козового, с 1984 в европейском частном собрании.

Задачей исследования является проверка гипотезы о возможности присутствия в коллекции Харджиева двух вариантов живописной картины Малевича, в которых использована композиция креста, с наложенным на него в центре белым квадратом. Период предполагаемого нахождения картины в Швейцарии является наименее изученным, поэтому следующий этап проверки провенанса связан с работой в архиве музея Асконы.

Обширное собрание Отдела, созданного в 1985 на основе даров коллекционеров и наследников художников, насчитывает более 10 000 экспонатов, среди которых значительная часть принадлежит мастерам русского авангарда начала ХХ в., художникам-нонконформистам и мастерам концептуального искусства второй половины XX–начала XXI в., etc.

Актуальным направлением деятельности отдела является также программа «Плеяда», ориентированная на сохранение, исследование и популяризацию творчества выпускников ВХУТЕМАСа, в русле которой лежит поступление крупного живописно-графического комплекса работ С.Никритина, происходящего из московской мастерской художника.

С.Никритин – представитель молодого поколения русского классического авангарда, в начале 1920-х экспериментировал в области беспредметного искусства, создал яркую авангардную теорию Проекционизм. После критики 1936 года оставил экспериментальное творчество, сосредоточился в пространстве сюжетно-фигуративного искусства, обогащенного пластическими приемами новаторского периода.

Наследие Никритина, переданное в дар ГМИИ, находится в стадии изучения, носит ретроспективный характер, отражает основные темы и характер творчества мастера, насчитывает несколько сотен произведений 1920-х–1960-х. Среди них – автопортреты, работы из известных циклов довоенных лет, подготовительные материалы к программной картине Старое и новое; многочисленные рисунки военного периода – эскизы агитплакатов, зарисовки прифронтовой и городской жизни. Оптимизм послевоенных лет отражен в колхозных и индустриальных сериях, этюдах южных приморских городов Советского Союза, многообразных пейзажах Москвы. Отдельную «главу» составляют произведения по «мотивам старых мастеров», исполненные преимущественно в Пушкинском музее.

Монографические собрания произведений Никритина хранятся в Третьяковской галерее, MOMus (Салоники), Нукусском музее. С поступлением в ГМИИ нового большого комплекса работ мастера музеефицирование его наследия близится к своему завершению.
Collecting before and after the October Revolution: the Archive of Nadezhda Dobychina
Authors: Muromtseva Olga
Published: November 2024

Dobychina’s name and her Art Bureau are mentioned in the bibliography dedicated to the history of modernism thanks to the “Last Futurist Exhibition. 0,10” which was held there in December, 1915–January, 1916. However, it should be noted though that Dobychina hardly belonged to the radical avant-gardists. Her interests as a collector and a curator in the pre-revolutionary years included artists of the World of Art and the Blue Rose groups, but she also had in her possession some artworks by Natal’ia Goncharova, Mikhail Larionov, David Burliuk, Natan Al’tman, Marc Chagall, Wassily Kandinsky.

The documents from the Dobychina’s archive, kept at the State Russian library, prove that she played an important role in the art field and acted as an art dealer both before and after the October revolution. In the early 1920s, she was in charge of the exhibition departments of the several institutions in Petrograd (Leningrad), from 1932 to 1934 she worked as a senior researcher at the State Russian Museum; after that she moved to Moscow, where she headed the Art Department of the Revolution Museum. Throughout these turbulent years she tried to keep her art collection. The three collection inventories, compiled in 1919, 1924 and 1930, show that some artworks constituted the collection’s integral part and not intended for selling.

The most striking paintings and graphics by Mikhail Vrubel’, Valentin Serov, Viktor Borisov-Musatov, Dmitriĭ Stelletsky, Alexandre Benois, Martiros Sar’ian, apparently, belonged to Dobychina for decades and were sold mostly after her death to the famous Soviet collectors – Solomon Shuster, Aram Abramian, Aleksandr Miasnikov, and Valeriĭ Dudakov.
Gustav Klucis (1895–1938): a Complex Transformation from “Soviet Artist” to “Russian Avant-Gardist”
Authors: Derkusova Iveta
Published: November 2024

The two main elements that render the case of Gustav Klucis unique among other Russian Avant-garde artists are: his nationality which was the cause of his tragic death during Stalin’s Great Purge but also what determined the fate of his creative legacy; and his political engagement in the development of mass (propaganda) art, which is behind the current controversial evaluation of his legacy today, and had influenced his own complicated career. Although both the circumstances of the artist’s life and the historical context are familiar to scholars, archival studies provide new materials, revealing less-known aspects of the artists’ creative biography.

My paper addresses two topics. In the introduction I recall some notable facts about the “Riga Collection” of Klucis’ works, kept at the Latvian National Museum of Art, and discuss how its interpretation and interrelation to other collections of Klucis’ works were developed with an eye towards the artist’s reintegration in the context of the Russian Avant-garde. In the main part of my paper, I share some thoughts about Klucis as a theorist, related to the study of the second version of his manuscript “The Right to Experiment” and other less known materials, found in the Nikolai Khardzhiev archive.
Increasing competitiveness of Holstein cattle breed in Moscow region

The Holstein breed of cattle was registered in the Russian’s "State Register of Breeding Achievements Approved for Use" in 1993 (application № 9352682). By that time, its relative abundance was 0,7 %. Over the past 28 years, despite the continuing decline in the number of dairy cattle in the Russian Federation the share of the Holstein breed has grown to 34,7 %, while for the vast majority of other breeds and almost all domestic breeds This indicator has significantly decreased: for the Red Steppe breed to 2,7 % (3 times), Kholmogor breed to 4,4 % (almost 2 times), Simmental breed — to 4,5 % (4,8 times). The relative number of Black-and-White cattle from 1993 to 2010 increased from 45,8 to 57,9 %, over the next 11 years it decreased to 42,4 %.

During the study period (from 1993—2021), in our country there was not only a reduction in the number of dairy cattle but also the replacement of domestic breeds for Holstein cattle (Red Steppe, Kholmogor, Simmental and Black-and-White).

The results of studies convincingly testify:

   milk production of Holstein breed increased annually by 29,4—150,0 % higher than that observed in animals of domestic breeds;

   consumer demand for pedigree Holstein heifers and primiparous is constantly growing while for animals of domestic breeds is declining and in the last 11 years, the annual demand for breeding Holstein breed has increased by an average of 3,7 %;

    the overall assessment of the body type of Holstein first-calf cows increased by an average of 0,3 points annually and at the same time productivity increased by 206,7 kg per year;

    if the identified rates of improvement of Holstein cattle are maintained in the near future, by 2026, the milk productivity of pedigree cows of this breed can reach an average of at least 11,0 thousand kg in milk yield, the fat content in milk is 4,20 % and protein is 3,40 %.
On the mod-2 cohomology of the product of the infinite lens space and the space of invariants in a generic degree
Authors: Phúc Đặng Võ
Published: November 2024

Let $\mathbb S^{\infty}/\mathbb Z_2$ be the infinite lens space. Denote the Steenrod algebra over the prime field $\mathbb F_2$ by $\mathscr A.$ The (mod-2) cohomology $H^{*}((\mathbb S^{\infty}/\mathbb Z_2)^{\oplus s}; \mathbb F_2)$ is known to be isomorphic to the graded polynomial ring $\mathcal {P}_s:= \mathbb F_2[x_1, \ldots, x_s]$ on $s$ generators of degree 1, viewed as an unstable $\mathscr A$-module. The Kameko squaring operation $(\widetilde {Sq^0_*})_{(s; N)}: (\mathbb F_2\otimes_{\mathscr A} \mathcal {P}_s)_{2N+s} \longrightarrow (\mathbb F_2\otimes_{\mathscr A} \mathcal {P}_s)_{N}$ is useful in studying an open problem of determining the dimension of the indecomposables $(\mathbb F_2\otimes_{\mathscr A} \mathcal {P}_s)_N.$ It has been demonstrated that this $(\widetilde {Sq^0_*})_{(s; N)}$ is onto. As a continuation of our recent works, this paper deals with the kernel of Kameko's $(\widetilde {Sq^0_*})_{(s; N_d)}$ for the case where $s = 5$ and the "generic" degree $N_d$ is of the form $N_d = 5(2^{d} - 1) + 11.2^{d+1}$ for arbitrary $d > 0.$ Our study also corrects almost all of the inaccurate main results in an earlier publication [Rev. Real Acad. Cienc. Exactas Fis. Nat. Ser. A-Mat. \textbf{116}:81 (2022)] by Nguyen Khac Tin. Furthermore, we have established several advanced algorithms in \texttt{SAGEMATH} to validate our results. As an application, we investigate the behavior of the cohomological transfer in bidegrees $(5, 5+N_d).$
The Impact of Focal Cortical Lesions on the Development of Cognitive Ability: Testing causality after the longitudinal analysis of 464 children
Authors: Protzko John , COLOM ROBERTO , Karama Sherif
Published: November 2024

Theories of cognitive development rely on implicit or explicit causal assumptions from developmental data. While powerful in their attempt to account for within-individual developmental change, causally testing such theories is difficult. One method for enhancing our knowledge might be to look for exogenous changes affecting mainly some cognitive abilities and to observe the developmental outcomes over further abilities. Focal cortical lesions sustained in childhood represent one informative instance of such changes. Here we test the implications of theories of cognitive development by studying a sample of 464 individuals who suffered focal cortical lesion in childhood to either the right frontal or right temporal lobes. Children had follow-up cognitive assessments done 8.5 years later. The key findings showed sustained long-term deficits in fluid abilities, but no developmental cascade of a reduction in abilities over time. Suffering a lesion to the right frontal cortex, despite causing a drop in fluid or abstract intelligence, does not transfer over to crystallized or knowledge-based abilities over development. The implication is that there is no transfer between these abilities when an exogeneous change affects early fluid ability. These results can be seen as powerful for testing developmental theories of cognition against their causal assumptions.
