ALTERNATIVAS DE AHORRO ECONÓMICO Y GENERACIÓN DE DIVISAS, MEDIANTE CAMBIOS EN LA MATRIZ ENERGÉTICA
Authors: Gardilcic Calvo Mirko
Published: December 2024

El presente artículo de investigación, está, orientado a proponer alternativas que posi- biliten cambios en la actual matriz energética, para alcanzar ahorros para la economía nacio- nal y a su vez contribuir con la generación de divisas que, hoy más que nuca resulta priori- tario en Bolivia. La estrategia en sí, simple- mente implica la sustitución del consumo de recursos de origen fósil (gas natural) por el uso de recursos hídricos (agua) para la gene- ración de energía eléctrica, sin descartar la posible utilización de otros recursos renova- bles, como los eólicos, solar, evaporíticos y biomasa, que a futuro pudieren contribuir de manera significativa.
Para dicho cometido, de inicio se expone un análisis cualitativo de la viabilidad técnica de los proyectos hidroeléctricos que existen en portafolio, para posteriormente poder demos- trar cuantitativamente, el beneficio econó- mico y financiero que, pudiera lograrse me- diante la implementación de esta alternativa tecnológica a mediano y largo plazo, frente a las plantas termoeléctricas que actualmente suponen la mayor fuente de energía eléctrica (más del 75 %) y que utilizan como combus- tible el gas natural subvencionado, que tanta falta hace a nuestra economía.
La mutación del tipo de tecnología propuesto, para la generación de energía eléctrica, podrá originar cuantiosos beneficios económicos y financieros a favor del Erario Nacional, con efectos redistributivos en la economía regio- nal, por el ahorro del consumo de gas natural que, además de disminuir considerablemente, ocasionó un drástico decremento en los ingre-sos por exportación, afectando la balanza de pagos, con la consiguiente insuficiencia de divisas en el País. Adicionalmente, se prevé lograr como externalidad positiva, la regula- ción del uso de agua para riego que, beneficia- rá trascendentalmente a la actividad agrícola. Pero posiblemente la gracia mayor, consista en disminuir el impacto en el medio ambien- te y la diversidad ecológica que, cada vez se encuentra más amenazada y con inminentespeligros de extinción.

En tal sentido, se demuestra a lo largo del trabajo de investigación, la innegable contri- bución al crecimiento y desarrollo económico de Bolivia.

DIVERSIFICACIÓN Y REGULACIÓN DEL CAMPO DE LA EDUCACIÓN SUPERIOR Y LAS UNIVERSIDADES
Authors: Yapu Condo Mario
Published: December 2024

Bolivia ha vivido un intenso proceso de diversificación social, económico, cultural y educativo en los últimos cuarenta años. Se ha reivindicado la diversidad cultural, lingüística y de los saberes indígenas, llegando a definirse como un Estado plurinacional en 2009, sin que esto cambie sustancialmente la desigualdad social, económica, regional y la emigración. En este escenario, este artículo analiza la educación superior, especialmente, las universidades, en su reposicionamiento, resistencia y cambios con relación al Estado, y entre ellas mismas como un campo de formación e investigación en conflicto. El trabajo se inspira del neoinstitucionalismo en sociología sintetizado por DiMaggio y Powell y de otros autores como Mary Douglas, Michel Foucault y Pierre Bourdieu cuyos abordajes varían, pero también comparten elementos comunes. Se inspira en ellos, pero no pretende hacer un debate teórico limitándose al nivel descriptivo. Discute las acciones institucionales del Estado y sus dispositivos que, más allá de la autonomía universitaria, pretende inducir el campo de acción de las universidades hacia sus políticas institucionales sin lograr afectar las rutinas y las regulaciones internas. En concreto, analiza el campo de las universidades en su interacción con el Estado, apoyándose en el análisis de la producción de normas correspondiente a dos reformas educativas nacionales. El objetivo es mostrar la diversificación del campo universitario y las estrategias de regulación desde el Estado.

Elasmobranch Conservation in India: Assessing Threats and Strategies for Sustainable Management
Authors: Makwana Ketan , Parmar H. L. , Ragul Sivakumar
Published: December 2024

Elasmobranchs, a group that includes sharks, rays, and skates, play a crucial role in marine ecosystems as apex predators and benthic regulators. However, they face significant threats that jeopardize their populations and overall biodiversity. Major threats include overfishing, bycatch, habitat degradation, pollution, and climate change. Overfishing, driven by high demand for shark fins and ray gills, alongside unregulated fishing practices, has led to drastic declines in many species. Bycatch in commercial fisheries further exacerbates their vulnerability. Additionally, habitat destruction due to coastal development and pollution impacts their breeding and feeding grounds. Climate change contributes to shifts in ocean temperature and acidity, affecting elasmobranch physiology and distribution. Effective conservation strategies are essential to address these threats and ensure the sustainability of elasmobranch populations. Key measures include implementing and enforcing sustainable fishing practices, creating marine protected areas, reducing bycatch through improved fishing gear, and enhancing global cooperation for conservation efforts. Addressing these threats requires a multifaceted approach involving scientists, policymakers, and local communities to safeguard the future of elasmobranch species and maintain the health of marine ecosystems.

O objetivo deste artigo é analisar as relações de sociabilidade entre antigos e novos residentes considerando o afluxo de pessoas para trabalhar como assalariadas na dendeicultura na vila Forquilha em Tomé-Açu (PA). Trata-se de um estudo de caso conduzido por meio de abordagem quantitativa e qualitativa, com revisão de literatura e levantamento de dados primários e secundários. Observações e entrevistas semiestruturadas e não diretivas foram realizadas com 46 antigos residentes (“os daqui”) e com 51 novos (“de fora”) que foram atraídos pelo assalariamento. Observações foram feitas nos lugares de residência e em espaços públicos de lazer e de serviços. As principais conclusões mostram que houve transformações nas relações de sociabilidade devido à chegada de pessoas para trabalhar. Evidenciam-se três tipos de interação social: entre os residentes “daqui”, entre os residentes “de fora” e entre ambos os tipos de residentes. A interação ocorre com maior fluidez no convívio intragrupos; entre um tipo e outro, é superficial, e a sociabilidade torna-se mais difícil em razão das diferenças.
Green-Economic Constructions Using Composite GFRP Closed Forms
Authors: M. Mohamed Hamdy
Published: December 2024

Green and Sustainability are big words these days. Recently, the demand for more green
construction or sustainable construction has been driven largely by consumers in the construction
sector. In this study, new filament wound glass fiber-reinforced polymer (GFRP) tubes are used
as an FRP-stay in place structural formwork for concrete beams. The test results of an
experimental study carried out on 230 mm diameter and 2000 mm long concrete filled FRP tubes
(CFFTs) beams are presented. Three CFFT beams and two control specimens without tube were
tested under four-point bending. One control specimen was reinforced with steel spirals of stiffness
equivalent to the GFRP tube and the other had no transverse reinforcement. The parameters used
in this investigation include the effect of laminate thickness of FRP tubes, the type of the internal
reinforcements (steel or GFRP bars) and the type of transverse reinforcements (spiral steel or
FRP tubes). The fiber orientations of the tubes were mainly in the hoop direction. The two control
specimens failed in shear; however, using GFRP tubes instead of transverse steel reinforcement
changed the mode of failure of the three CFFT beams to flexural failure. In addition, the GFRP
tubes confine the concrete core which subsequently increases the ultimate compression capacity
and the ductility of the specimens. Also, test results indicate that the GFRP tube enhances the
flexural strength of the specimens, whereas it provides a longitudinal reinforcement in the tension
side.

Published: December 2024

In all over the word, COVID 19 has created uncertainty and panic situation in almost all areas of
life. Not only financial position of all countries has been badly affected but also internal and
external social lives have also disturbed badly. If we talk about Bahrain and its economy, all large
scale businesses in general and small and medium sized businesses have dropped up to their
alarming position. Major victims of the COVID-19 outbreak are micro, small, and medium-sized
businesses (SMEs). This article aims to assess the impact of COVID-19 outbreak on these
businesses and provide policy recommendations to help SMEs in reducing business losses and
survive through the crisis. The study adopted an exploratory methodology with comprehensively
reviewing the available literature in the relevant field. Further, to add empirical evidence, we
collected data from some Bahraini SMEs by administering an online questionnaire. The data were
analyzed through descriptive statistics. The results indicate that most of the participating
enterprises have been severely affected and they are facing several issues such as financial, supply
chain disruption, decrease in demand, reduction in sales and profit, among others. Besides, over
75% of enterprises were neither prepared nor have any plan to handle such a situation. The
findings of our study are consistent with previous studies. Based on the results of the research,
different policy recommendations were proposed to ease the adverse effects of the outbreak on
SMEs.

Authors: Srour Heba , Azmy Ahmed
Published: December 2024

The paper is aiming at assessing the effect of cash conversion cycle on firm
profitability. Three components are used to measure cash conversion cycle
(CCC); average collection period (ACP), average inventory period (AIP) and
average payable period (APP). Henceforth, cash conversion cycle and its
determinants are taken as independent variables. The dependent variable is
profitability being measured by return on asset (ROA) and return on equity (ROE).
For the period 2016-2020, data was collected from companies listed on the EGX,
regression models are used to test the Hypothesis with a sample of seven firms from
various industries. The paper’s results are consistent to those of (Telly & Ansori,
2019), and (Rizky & Mayasari, 2018) showed that, the average collection period
and average inventory period have an inverse association with the firm’s
profitability (ROA), with the exception of the average payable period.
Keywords: Cash Conversion Cycle – Profitability – Return on Asset – Return on

The Role Of Aesthetic Procedures In Long-term Wound Management
Authors: Hetz Dr. Samuel
Published: December 2024

The role of aesthetic procedures in long-term wound management is a growing field that combines known dermatological procedures with tailored care plans to enhance healing and improve outcomes for patients with certain wounds, including surgical incisions, tumours, and ulcers. Long-term wound management refers to the positioning of aesthetic procedures as a solution during the later stages of wound healing, most commonly the proliferation and maturation stages. This article will explain the science behind scarring, the role of micro-wounds in aesthetic procedures, and how collagen production influences the latter stages of wound healing. The necessary cautions and considerations for each procedure will also be discussed. The article will inform wound care teams about the potential benefits of aesthetic procedures in long-term wound management, ultimately contributing to enhanced patient care and quality of life.

In this paper, we discuss the atomic solutions of the abstract Cauchy problem in two variables. The proposed abstract Cauchy problem is assumed to be non-homogeneous and in tensor product form. We utilize some results from the theory of tensor product of Banach spaces to obtain solutions in the atom operator form. The approach is applied for both ordinary and α-conformable fractional derivatives.
On the Lichnerowicz-Poisson cohomology complex and quasi-Poisson algebras
Authors: Iskamle Bruno , Tcheka Calvin , Dongho Joseph
Published: December 2024

This article explores F-commutative algebra (A,·) with Poisson structure defined by a non-Lie algebra bivector Q. We analyse the Lichnerowicz-Poisson coboundary δ*Q and its implications as a quasi-Poisson structure, where the Schouten bracket does not vanish, complicating cohomology computations. The examined open question is whether the deviating term is a coboundary of Poisson cohomology. Our main objectives are to construct a Poisson subalgebra on which the twisted term δ2Q(Q) vanishes, and to study the existence of Poisson structures P on a Poisson ideal satisfying the condition δ2P(·) = δ2Q(Q).
On block-related derived graphs
Authors: Baskar Nivedha , Mangam Tabitha Agnes , Raja Rohith
Published: December 2024

The cut vertex of a graph G is a vertex whose removal increases the number of components in the graph. A maximal connected subgraph with no cut vertex is called a block of the graph. This paper introduces and analyses the block-degree of a vertex and the cut-degree of a block. The block-degree of a vertex v is the number of blocks containing v. The cut-degree of a block b is the number of cut vertices of G contained in b. Given the block-degree sequence of cut vertices of a graph, the number of blocks of the graph and bounds on the order and size of the graph are studied. The block graph (B(G)) of a graph G is the graph whose vertices are blocks of G in which two vertices are adjacent whenever the corresponding blocks have a vertex in common. The number of cut vertices in B(G) is obtained and the graphs for which B(G) has exactly one cut vertex are characterized. Further, an investigation is carried out on the traversability of B(G). The block cut point graph BC(G) of a graph G is the graph whose vertices are the union of the set of blocks and the set of cut vertices of G and in which two vertices are adjacent if it corresponds to a block b of G and the other to a cut vertex c of G and c belongs to b in G. The properties of BC(G) and its iterations are studied. The graph G for which BC(G) is a perfect m-ary tree is characterised.

Published: December 2024

This paper presents a new type of semiderivation in ring, called a (f, g)-semiderivation, where f and g are are self-mappings of a ring. We explore various properties of (f, g)-semiderivations and demonstrate that if a semiprime ring R satisfies specific differential identities involving a (f, g)-semiderivation D, then D must be a zero map on R. Additionally, we examine the commutativity of prime rings that admit nonzero (f, g)-semiderivations which satisfy certain differential identities.

Published: December 2024

Ekonomik özgürlük ve finansal derinleşme arasındaki ilişki, ülkelerin ekonomik büyümesi ve kalkınması için önemlidir. Finansal derinleşme kavramı ülkelerin finansal sisteminin genişlemesi ve derinleşmesi anlamına gelmektedir. Ekonomik özgürlük kavramı ise kişilerin ekonomik faaliyetlerde bulunma özgürlüğünü, mülkiyet haklarının güvenliğini, ticaret özgürlüğünü ve devlet müdahalesinin derecesini ölçen bir göstergeyi ifade etmektedir. Bu bağlamda iki kavram arasındaki ilişki, ekonomik kalkınma ve istikrar için önemli arz etmektedir. Bu çalışmada E7 ülkelerin finansal derinleşme ile ekonomik özgürlük endeksi, doğrudan yabancı yatırım ve portföy yatırımları değişkenlerinin 1995-2024 yılları arasındaki oluşturulan yıllık veri setiyle korelasyon, eş bütünleşme ilişkisi ve nedensellik analizleri yapılmıştır. Korelasyon analizi sonuçlarına göre finansal derinleşme ile ekonomik özgürlük arasında negatif doğrudan yabancı yatırımlar ve portföy yatırımları arasında ise pozitif bir korelasyonun olduğu tespit edilmiştir. Değişkenler arasında bir eş bütünleşme ilişkisi tespit edilememiştir. Nedensellik analizi sonucunda finansal derinleşme ile doğrudan yabancı yatırımlar arasında çift yönlü bir nedenselliğin olduğu tespit edilmiştir. Ayrıca finansal derinleşmeden ekonomik özgürlük ve portföy yatırımlarına doğru tek yönlü bir nedenselliğin olduğu tespit edilmiştir.

Authors: De Carvalho Messora Thereza Cristina , Pinter dos Santos Adriano
Published: December 2024

Introdução: A febre amarela é uma doença infecciosa com ocorrência em surtos espaçados temporalmente. No ano de 2016 iniciou-se a maior circulação epizoótica do ciclo silvestre da doença na região Sudeste do Brasil. Objetivo: Descrever a experiência de um município frente à dispersão do vírus amarílico e sua estratégia de vacinação. Metodologia: Trata-se de um relato de experiência realizado em um município do interior do Estado de São Paulo no ano de 2017. Resultados: Os macacos bugios apresentaram valor preditivo positivo como espécie sentinela, demonstrando um padrão de dispersão no sentido norte-sul do território, de acordo com a teoria de corredores ecológicos. Foram aplicadas 3.952 doses de vacina na estratégia domiciliar em áreas rurais ou próximas a fragmentos florestais. Não houve registro de casos e óbitos humanos. Conclusão: A vigilância geoespacial da circulação viral possibilitou o planejamento da estratégia de imunização para populações prioritárias em um cenário de oferta insuficiente de vacina, atuando de forma preventiva e oportuna na redução de casos humanos, com potencial de replicação em cenários de risco futuros.

O(s) modelo(s) silábico(s) do emakhuwa (P31) parece diferir(em) da língua portuguesa, embora tenham em comum a estrutura mais atestada nas línguas naturais, i.e., CV. Partindo desta premissa, mostra-se interessante proceder a análise contrastiva das duas línguas, tendo como escopo do estudo a sílaba, para entender a composicionalidade em emakhuwa. Da avaliação de estruturas pouco comuns na língua, essencialmente formadas por sequências consonantais e vocálicas, em empréstimos nominais do português, conclui-se que o emakhuwa pauta pelo modelo canónico da sílaba CV, embora em situações pontuais possam ocorrer na língua outros tipos de sílabas, a exemplo de V, N, VV e CVV. Entretanto, o formato CV(V)C ocorre apenas em alguns casos de estruturas emprestadas do português.

Published: December 2024

This paper aims to describe LLM-SEMREL, a new Portuguese semantic database built automatically using currently available large language models. The motivation for this project stems from the lack of rich semantic resources for the Coreference Resolution task in Portuguese. As a result, we provide a new resource that can be used to improve current models and build new ones. LLM-SEMREL is composed of 1,229,399 semantic relations, distributed among 261,731 words and their descriptions.

оптимизация портфеля представляет собой задачу многомерного характера, где необходимо учитывать различные критерии, такие как минимизация риска, достижение целевого уровня доходности и обеспечение диверсификации активов. В исследовании использован подход, основанный на минимизации стандартного отклонения доходности портфеля при заданных ограничениях на доли активов, что предотвращает чрезмерную концентрацию капитала на одном активе. Особое внимание уделяется использованию энтропийного показателя для оценки степени диверсификации, что позволяет равномерно распределять капитал среди активов и снижать концентрационные риски. Для оценки риска портфеля используется ковариационная матрица доходностей активов, что позволяет более точно учесть корреляции между активами. В результате были получены оптимальные портфели, характеризующиеся приемлемым уровнем риска и доходности. Представленные результаты показывают, что методы нелинейного программирования обеспечивают эффективное решение задач портфельной оптимизации, минимизируя риски и обеспечивая устойчивость к рыночным колебаниям. Исследование подчеркивает важность интеграции показателей диверсификации и риска для создания сбалансированных инвестиционных портфелей, что делает предложенный подход полезным для практического применения в управлении активами.

portfolio optimization is a multidimensional task that requires considering multiple criteria, such as risk minimization, achieving a target return level, and ensuring asset diversification. The study employs an approach based on minimizing portfolio return volatility under constraints on asset shares, preventing excessive concentration of capital in a single asset. Special attention is given to the use of an entropy measure to evaluate the degree of diversification, allowing for balanced capital allocation among assets and reducing concentration risks. The portfolio's risk is assessed using a covariance matrix of asset returns, which more accurately captures the correlations between assets. The results demonstrate optimal portfolios characterized by acceptable levels of risk and return. The findings indicate that nonlinear programming methods provide an effective solution for portfolio optimization, minimizing risks and ensuring resilience to market fluctuations. The study highlights the importance of integrating diversification and risk measures to create balanced investment portfolios, making the proposed approach valuable for practical asset management applications.

данная статья посвящена разработке метода генерации синтетических данных для задач линейной регрессии. Итоговый метод позволяет генерировать данные различных размеров и позволяет пользователю контролировать особенности полученной регрессии. В нём реализована возможность добавить гетероскедастичную ошибку, авторегрессию в ошибках, сильно скоррелированные зависимые переменные, переменные не связанные с зависимой переменной, а также варьируемую зашумлённость как зависимых, так и независимой переменных. Помимо теоретического подхода прилагается реализация метода на языке программирования Python, а также примеры применения кода с различными тестами. В результате был разработан метод, позволяющий генерировать синтетические данные с требуемыми параметрами для проверки точности или скорости методов оценки линейных моделей или для изучения работы алгоритмов линейной регрессии при различных особенностях «истинной» модели или неточностей в получении данных в реальных условиях.

this article is devoted to the development of a method of generating synthetic data for linear regression problems. The resulting method can be used to generate data of various sizes and allows the user to control specifics of resulting regression. It has the option to add heteroscedastic error, autoregression in errors, strongly correlated dependent variables, variables not related to the dependent variable, as well as variable noise of both dependent and dependent variables. In addition to the theoretical approach, there is also an implementation of the method in the Python programming language, as well as examples of implementation given some sets of parameters with various tests. As a result, a method was developed that allows generation of synthetic data with the required parameters to test the accuracy or speed of linear model evaluation methods or to study the application of linear regression algorithms under various specifics of the "true" model or inaccuracies in obtaining data in real conditions.
