O impacto da taxa Selic na bolsa de valores brasileira sob a perspectiva da aversão à perda
Authors:   , Mariano Gustavo Escobar
Published: December 2024

Este estudo examina como a variação da taxa Selic afetou o comportamento dos investidores brasileiros na Bolsa de Valores (B3) entre 2021 e 2022, com foco especial na aversão à perda. Baseando-se na Teoria do Prospecto, de Kahneman e Tversky, que sugere que as pessoas são mais sensíveis às perdas do que aos ganhos, o estudo analisa a tendência dos investidores de buscar segurança em ativos de renda fixa, especialmente em momentos de alta nos juros. Nos períodos de aumento da Selic, a renda fixa se torna mais atrativa por oferecer retornos garantidos, desviando o interesse de muitos da renda variável, que é considerada de maior risco. A pesquisa mostra que, nesse contexto, há uma mudança na perda de influência significativamente nas decisões de investimento, motivando uma migração para ativos mais seguros e menos voláteis. Esse comportamento reflete uma preferência por evitar perdas potenciais em detrimento de ganhos possíveis, o que tem implicações importantes para o mercado de ações e a economia em geral. A conclusão ressalta que, em cenários de inflação elevada e juros altos, a versão à perda entre investidores brasileiros se acentua, moldando a dinâmica de alocação de ativos no país.

Authors:   , Araujo Neto Joel de
Published: December 2024

Este artigo tem como objetivo analisar o impacto das práticas de ESG (Environmental, Social and Governance) na eficácia financeira das empresas listadas no Índice de Sustentabilidade Empresarial (ISE) da B3, focando em uma comparação setorial. A pesquisa investiga como a adoção de critérios ESG influencia indicadores financeiros como ROE, ROA, ROIC e Margem EBITDA, abrangendo o período de 2016 a 2018. A hipótese central é que a implementação dessas práticas pode resultar em melhorias financeiras a longo prazo, embora não assegure lucros imediatos. Os dados foram coletados de relatórios anuais e trimestrais, permitindo uma análise abrangente da relação entre sustentabilidade e desempenho financeiro. Os resultados indicam que a hipótese foi parcialmente aceita. Observou-se uma correlação positiva moderada entre práticas sustentáveis (ESG) e alguns indicadores de eficiência financeira, como ROA e Margem EBITDA, enquanto a correlação com ROE e ROIC foi fraca, o que sugere que o impacto das práticas ESG sobre a eficácia financeira varia de acordo com o indicador e pode não ser imediato em alguns casos, sendo mais perceptível em indicadores operacionais de curto prazo.
Cognição, compreensão e algoritmos
Authors: Nöth Winfried
Published: December 2024

Algoritmos são regras gerais que guiam computadores na resolução de problemas e execução de trabalhos. Nisso, eles fazem computadores interpretar e produzir signos. Um algoritmo é um legissigno simbólico argumentativo, o que implica que eles são agentes semióticos e participam em processo cognitivos. Implementados em máquinas de IA, os algoritmos também interpretam ícones diagramáticos, mas diferentemente dos humanos não ícones da classe das imagens. – Máquinas inteligentes agem como extensões cognitivos de cérebros humanos. Os riscos da extensão da inteligência humana para inteligência artificial são riscos que existem desde que a comunicação humana tem sido estendida a lugares distantes, onde foram interpretados na ausência dos emissores e começaram a adquirir uma autonomia além do controle dos emissores dos signos.
Musical topics, (self-)narrativity and adaptation in my recent composition Pearl
Authors: Matthew Kaner
Published: December 2024

This exposition charts the creation and musical-narrative structure of Pearl, my recent composition for symphony chorus, orchestra, and solo baritone: a setting of extracts from the medieval poem Perle, translated into modern English by Simon Armitage, commissioned as part of the BBC Proms in 2022. Envisioned as a contemporary adaptation of the poem’s historically distant, yet somehow timelessly poignant and continually resonant story, Pearl takes the form of a musical narrative that evokes both past and present, through personal and more universal reflections on the nature of loss, grief, and acceptance. By drawing together analytical techniques taken from musical theories of narrative (principally Byron Almén 2008), musical topics, and the adaptation of narratives across media (Marie-Laure Ryan 2014), with a self-narrative approach to documenting my practice in action (as advocated by Christopher Leedham and Martin Scheuregger 2018), I unpack my creative approach to Pearl in what might be understood as ‘bricolage’ as proposed by Robyn Stewart (2007). Constructing a ‘new story’ through a ‘plurality of approaches’, I adopt Stewart’s methodological eclecticism to theorize and situate the work as a musical narrative. However, through the slippage that occurs between narratology and self-narrativization, Pearl is shown to also mirror and situate my personal artistic experiences as a contemporary practitioner. In response to the recent and ongoing debate about the nature and validity of Practice Research in Composition, the article addresses calls to share the ‘messy, complicated, uncertain, and soft’ (Arthur Bochner 2000) aspects of the artistic process suggesting a more open, and even collaborative, role for the sharing of compositional research.

La « capitulation » de Stjepan Radić et l’échec de sa politique de coopération avec Belgrade
Authors: Kovač Miro
Published: December 2024

Après la création du Royaume des Serbes, Croates et Slovènes en décembre 1918 le président du Parti paysan croate Stjepan Radić devint le leader du mouvement national croate. Confronté à l’échec de sa politique obstructionniste, sans aide substantielle d’une puissance étrangère pour « affranchir le peuple croate » de la « tyrannie serbe », mis en prison pour avoir « conspiré avec les Soviets », en juillet 1925 il accepta finalement de coopérer avec « Belgrade », notamment avec ennemi politique et geôlier Nikola Pašić, le chef du Parti radical national. Arriver à une « paix » entre Croates et Serbes et consolider le royaume balkanique allié, ce fut également le souhait de la France officielle, dont le président du Conseil Édouard Herriot n’avait pas manqué d’user de son influence au sein de la presse de gauche pour promouvoir cette idée. Radić abandonna alors sa politique obstructionniste, reconnut la Constitution centralisatrice du Vidovdan, abjura le républicanisme, leva son opposition au service militaire, et entra même au gouvernement de Pašić comme ministre de l’Instruction publique. Cependant, ainsi Radić se révéla encore plus dangereux pour la caste politico-militaire serbe. Car non seulement le « trublion croate » gênait le fonctionnement du gouvernement, mais, au surplus, il tâchait d’élargir sa base électorale majoritairement paysanne aux dépens de celle de ses « partenaires » radicaux. En avril 1926, il fut invité à se retirer du ministère, et en janvier 1927 il mit fin à la coopération avec le Parti national radical. Son échec de s’implanter en Vieille Serbie l’amena à s’allier à un autre ancien ennemi mortel, Svetozar Pribićević, l’énergique Serbe ex-habsbourgeois, avec lequel il forma, en novembre 1927, la Coalition démocrate paysanne (SDK), formation qui regroupait la majorité des Croates et des Serbes de l’ancien royaume triunitaire. Le nouveau bloc des prečani fut la plus dangereuse force d’opposition dans la courte histoire du royaume, et il n’est guère surprenant que le roi Alexandre s’efforçât de le briser à tout prix.

Authors: Shin Man-Seok , Kang Sung-Ryong , Kim Bo-Ra
Published: December 2024

In this study, distribution data and environmental information for predicting the potential habitat of amphibians and reptiles in South Korea were compiled. The distribution data of amphibians and reptiles include nationwide surveys conducted by the National Institute of Ecology (seven surveys) and the Korea National Park Service (one survey). The distribution data are based on 57,777 locations for 35 species. Environmental information related to the habitat of amphibians and reptiles was constructed from 19 bioclimatic variables related to climate and four spatial variables related to geographic factors, and 19 bioclimatic variables for the future (2020-2090) were constructed using the results of SSP scenarios. In addition, species distribution models (MaxEnt) were used to predict current and future potential habitat for 28 amphibian and reptile species with more than 50 survey sites. The model validation values for the 28 species ranged from 0.717 to 0.987. These data have the potential to inform conservation strategies in response to climate change by spatially identifying current and future potential habitat for amphibians and reptiles.

Impact of Climate Change on Human Health: A Review of Literature
Authors: Y Farooqi , K Akhtar , SH Arif
Published: December 2024

Background: The present article was written with the background knowledge of climate change and highlighting it relationship
with health issues especially in tropical and Sub-Saharan African regions. There is a significant impact of global climate change
on human health. This article highlighted the fundamental pillars of health including food security, air quality and water safety.
Introduction: An anthropogenic activity such as urbanization, industrialization, and infrastructure development needs land.
Deforestation is one of the straightforward ways to acquire lands for these developments. Large scale of deforestation taken
place in last century led to increase of Green House gas (GHG) emission which subsequently led to global warming. Increase
in atmospheric temperature led to many health problems notably, increase in incidence of infectious disease, emergence of
new infectious agents, respiratory and cardiovascular diseases. Further, increased GHG emission led to depletion of ozone
layer and increased quantity of UV radiation on earth causes various form of malignancies in human beings apart from poor
air quality which contain particulate matters (PM), responsible for cardiovascular, respiratory illness and lung cancers. The
effort of global environmental organization is to agree to cut the GHG emission to hold the increase in the global average
temperature to well below 2°C above pre-industrial levels and pursue efforts to limit the temperature increase to 1.5°C above
pre-industrial levels as per Paris agreement 2015, so that emergence of diseases and increase in incidence of these disease
can also be decreased.
Aims: This article aims to highlight the impact of climate change on health and to find out the possible measures to reduce the
GHG emission and increase the quality of health affected by climate change and global warming.
Conclusions: Active measures should be planned and implemented by local bodies and international organizations and
to devise effective global strategies for mitigation and adaptation so that the adverse effect of climate change may not be
detrimental to human health.

Published: December 2024

Adoption of traditional gendered roles in managing streams in most Nigerian communities, have raised concerns over its
sustainability. Using the concepts of gender analysis and sustainable water management (SWM), we examined the traditional
roles played by men and women in managing Ezekoro stream in Achina, Anambra State, Nigeria. Qualitative, laboratory and
secondary data analysis were used in the study. We adopted purposive sampling to recruit a total of 24 community members
between18 to 60 years and above:12 women and men for FGD (6 each group), 2 key informants were interviewed (oral
histories)-the oldest man and woman leader in the community and 10 participants randomly selected for in-depth interviews.
Also, photographs and physiochemical and biological analysis of water samples from Ezekoro stream were used. Findings
unveil that traditional sanctions were used to separate. Ezekoro stream into male and female sections. Females carried out
domestic activities in their section while the male section was preserved for drinking. Again, sanctions restricting human
actions such as farming, sand mining, wood logging, open defecation, around the stream area were not effective. Elderly and
unmarried women found it difficult to access drinking water from the male section of the stream. Further, water samples from
the female section indicated that phosphorus, fluoride, copper and total coliform, bacteria count and fecal coliform were above
the permissible NESREA standard while sample from the male section had traces of total coliform, signifying the presence of
disease-causing organisms. Obviously, the practiced gender separation was ineffective, since there were traces of pollutants
in drinking water sourced from the male section. For optimal results, we recommend inclusiveness and gender equality,
maximize youth efforts and intensify awareness on water quality protection. Also, developing adaptive capacity for floods,
integrating regular water quality assessments to checkmate possible health risks.

Authors: D Bhumika , M Priya , K Vidit , J Namit , Y Harshwardhan , Y Satyanarayan
Published: December 2024

The sustainable use of medical waste in the construction sector has gained attention as an innovative solution to address the
growing environmental concerns linked to biomedical waste disposal. Medical waste contributes significantly to pollution, and
its effective management is vital to safeguarding both public health and the environment. Simultaneously, the construction
industry, as one of the largest consumers of natural resources, generates considerable waste. Integrating medical waste
into construction materials offers a dual benefit-minimizing the environmental footprint of the construction industry while
providing an eco-friendly solution for managing medical waste. This paper provides a comprehensive review of the current
research on the sustainable incorporation of medical waste into construction materials. It examines various methods of medical
waste utilization, identifies the challenges and opportunities this approach presents, and explores the policy and regulatory
frameworks that support sustainable medical waste management. The paper concludes by emphasizing the potential of
this approach to promote a circular economy, reduce the environmental impact of waste management, and underscores the
importance of further research and cross-industry collaboration between the medical and construction sectors.
Human-Induced Bushfires Threat to Biodiversity in the Noun Valley, Cameroon
Authors: EN Ngum , SJP Tume
Published: December 2024

The study examines the relationship between bushfires and their impact on the flora, fauna, and soil of the Noun Valley. This
was done using remotely sensed data from MODIS Fire and Global Water Pack datasets and field observations to arrive at the
desired results. During the height of the dry season, various plant species in the wetland forests, grasslands, and cultivated
fields, such as eucalyptus, palm trees, coffee, and cocoa, are highly susceptible to fire damage. Refugial forests, shrubs, and
pasture lands on the valley's hillsides are particularly at risk, often due to fires sparked by cattle grazers moving towards the
wetlands at the start of the dry season. The valley's significant agricultural potential has increased the incidence of humaninduced fires in the riparian villages. As the vegetation experiences stress, the safety of many animal and bird species is
compromised as their habitats and food sources are gradually destroyed. The valley's diverse ecosystems respond differently
to bushfires in terms of recovery, impacting the survival of habitats and potentially leading to the migration of species to safer
areas. Mitigation strategies are essential to reduce the impact of bushfires, and it is crucial to promote behavioural changes,
community awareness, and policy adjustments. Accurately predicting the effects and specific risks of similar incidents remains
a challenge.

Published: December 2024

The waste problem in Bandar Lampung is becoming increasingly critical as the volume of domestic waste reaches 1,283 tons per day. Ineffective management can lead to negative impacts on public health and the environment, such as the spread of diseases and pollution. This study aims to design and test a household-scale incinerator that is effective, efficient, safe, and low in pollution as an alternative solution for waste management. The designed incinerator is capable of burning 30 kg of waste in 180 minutes, using a fuel mixture of used oil and gasoline amounting to 130 ml. Test results show that the thermal efficiency of the incinerator ranges from 70-75%, with a charcoal yield of 14.42% and an ash yield of 11.53%. The overall efficiency reaches 77.05%, indicating that this device can optimally utilize the energy produced from combustion. This research demonstrates that a household-scale incinerator can be an effective solution for reducing waste volume and minimizing negative impacts on the environment. Recommendations for future research include the development of the incinerator design, evaluation of the temperature control system, and analysis of emissions generated from various types and compositions of waste. Thus, this study makes an important contribution to more environmentally friendly and sustainable waste management in Indonesia. Keywords: Combustion, Development, Design, Incinerator, Waste, Used Oil, Yield.

Authors: Kepeshchuk Denis , Bas Olexandr , Kepeshchuk Taras , Serediuk Denis , Pelikan Yuriy , Shevchuk Volodymyr
Published: December 2024

The paper presents the results of studies of the influence of pure gaseous hydrogen and gas-hydrogen mixtures and the performance and metrological characteristics of membrane-type gas meters used in the household sector. For the study, membrane-type meters of leading domestic and European manufacturers were pre-selected. A series of static and dynamic tests were conducted for the meters. The static tests involved checking the air-tightness of the meters under the influence of gaseous mixtures. The dynamic tests involved measurements on a simulated test site with a work medium of pure hydrogen as well as hydrogen-methane mixtures. The proportions of the mixtures used were: 80% of methane and 20% of hydrogen, and 90% of methane and 10% of hydrogen respectively. A structural diagram of the measuring system was developed. The measurements were performed by comparing the volume of the gas that passed through the experimental meter with the volume measured by the reference meter. The measuring system was equipped with a means for measuring the pressure and temperature of the measuring medium to bring the results of the experiments to standard conditions. As a reference means in the assembled measuring system, a drum-type gas meter with a calibration characteristic pre-determined under laboratory conditions with a work air medium was used. After the experimental studies with the work hydrogen medium and hydrogen gas mixtures under the conditions of the test site, the metrological characteristics were re-determined under laboratory conditions for the reference meter. To conduct the experiments with the maximum possible accuracy and to exclude the influence of additional errors on the measurement result, a specialized software was developed to automate the measurements of the volume of the gas passing through the reference meter, measuring the pressure and temperature of the work medium and fixing the required value of the gas volume flow rate. The results of the experiments for several meters are presented in the form of tabular values and graphs. General conclusions were made regarding the influence of hydrogen and gas-hydrogen mixtures on the change in metrological characteristics of household gas meters.
The determination of colour differences when calculating the colour rendering index
Authors: Hovorova Kateryna , Hryhorieva Yevheniia , Harmash Bohdan , Gulevskyy Sergiy , Malkova Iryna , Diumin Eduard
Published: December 2024

The paper addresses the issue of determining the reference light source when calculating the colour rendering index (CRI) and highlights a longstanding recognition of the importance of accurately conveying the shades of illuminated objects by light sources. Certain fields, such as garment and textile factories, art workshops, museums, printing houses, beauty salons, and dental offices, necessitate high-quality colour rendering to successfully perform their work. Improving the quality characteristics of lighting installations is essentially a risk-based approach to operating conditions, including the provision of the conditions that meet current international occupational safety standards. In 1965, the Colour Rendering Index (CRI) was introduced as a method to assess the colour accuracy in light sources, now mandated for testing by international standards for the LED equipment manufacturers.
The practical significance of the colour rendering index is based on the fact that the perception of lamp light by the human eye depends not only on quantitative characteristics (illumination, luminous flux), but also on qualitative characteristics, the negative indicators of which may affect the entire lighting system, that is, create the impression that “the lamp is shining, but does not illuminate”. As a result, this indicator has a direct effect on the energy efficiency of a lighting installation, where, to compensate for the “lack of light”, the power consumption of the installation is increased, instead of improving the quality of lighting, by replacing light sources with other sources with a high colour rendering index.
A crucial aspect of the CRI calculation involves determining the reference light source based on the colour difference determination. The approach aims to minimize the uncertainty by studying a reference emitter with a colour temperature similar to the tested light source. However, this criterion neglects the heterogeneity of colour perception, although it eliminates the need to consider changes in the eye adaptation states. To address this limitation, having analysed the standards on colorimetry, a formula for calculating the colour difference was proposed for the first time. The formula accounts for the heterogeneity in the perception of colour space, providing a more comprehensive approach in calculating the colour rendering index.
Metrology and economics: on the choice of the best options for the development of metrology systems by the criterion of minimum necessary costs – a review
Authors: Prokopov Alexander , Skliarov Volodymyr , Krasokha Liliia , Oliinyk Alla
Published: December 2024

A general approach to substantiating the best ways to develop national metrology systems based on minimizing the financial investments needed is formulated. The methods that have been developed at the NSC “Institute of Metrology” for estimating the effectiveness of investments for different possible options of functionality of metrological infrastructure elements related to certain types of measurements are analysed. In particular, the following options have been considered: a state primary (national) measurement standard of a unit that has passed international comparisons; there is no primary measurement standard yet, but it is being developed; there is no primary measurement standard yet and it is not being developed; a calibrated abroad secondary measurement standard used as a reference standard in the absence of a primary one.
The paper presents mathematical algorithms for analysing the economic feasibility of investments, which allow choosing the least costly solutions. An approach to calculating the payback period of the investments that takes into account inflationary processes is proposed.
Examples of application of the developed algorithms to analyse the economic feasibility to establish measurement standards, specifically, state primary measurement standards of the unit of volume activity of radon-222 and luminous intensity, are given. The algorithms presented in the paper for selecting the best options for the development of metrology system and increasing the efficiency of investments in metrology are especially relevant for countries with limited financial resources.
The Effect of STEM-Based Interventions on Learning Outcomes in High School: A Meta-Analysis
Authors: Fadillah Muhammad Aizri , Hirahmah Atifah , Asrizal  , Usmeldi
Published: December 2024

While numerous studies have investigated the effectiveness of STEM (Science, Technology, Engineering, and Mathematics) education, findings remain fragmented, and variations in research designs, sample characteristics, and contexts of implementation pose challenges in drawing generalized conclusions. This study aimed to assess the efficacy of the STEM approach on student learning outcomes at the high school level through a meta-analysis. A total of 24 studies that met the inclusion criteria were analyzed from 14 papers that met the criteria. The meta-analysis results demonstrated that the STEM approach was significantly more effective than traditional learning methods, with an overall effect size value of d = 1.71, Z = 7.45, and a significance level of P < 0.00001. Although there was considerable heterogeneity among the effect sizes (Q = 589.66, I² = 96%), the funnel plot demonstrated a symmetrical distribution of effect sizes, indicating minimal publication bias. The findings substantiate that STEM-based education can enhance student engagement, facilitate concept comprehension, and cultivate critical thinking abilities. The practical implications of this study include recommendations for education policymakers to design more effective STEM programs and for educators to adopt STEM-based teaching strategies. Various stakeholders must collaborate to guarantee this initiative's successful implementation and adequately prepare students for the global challenges they will encounter in the 21st century.

The Seljuk Turks’ victory at the Battle of Manzikert (1071 AD) and their entry into Anatolia marked a new chapter for this ancient land. The emergence of the Sultanate of Rum led to extensive political, social, and cultural transformations in the region. Gradually, with the consolidation of Seljuk rule, nomadic and urban Turks, drawn by the promise of prosperity and security in Anatolia, crossed the deserts of Central Asia and flocked to Anatolia in droves. To strengthen the foundations of their weakening caliphate in the 6th-7th/12th-13th centuries, the Abbasid caliphs supported the futuwwa movement. They joined them and encouraged their vassal rulers to do the same, spreading futuwwa throughout the Islamic lands. The Mongol invasion prompted a migration of scholars and Sufis to Anatolia, where they found refuge under the Seljuk kings. The kings’ support for futuwwa and Sufism and socio-political changes in the region led to various Sufi orders in Anatolia. Despite its combative stance against the Seljuks, the Alevi-Bektasi order became one of the most influential Sufi movements in the region and was significantly impacted by the Akhis tradition. Alevi Bektasi order was influenced by futuwwa ideas and practices. Some of their rituals in Jam ceremony are similar to futuwwwa. With the rise of the Alevi-Bektasi order during the Ottoman period, many Akhi members joined this order. The simplicity of teachings, emphasis on action, and the presence of Shia rituals in both groups brought them closer together and eventually united them. This paper examines the influence of them on the Bektasism, highlighting the similarities between the two movements that eventually led to their integration.
