Trabalho invisível das mães no cálculo da pensão alimentícia
Authors: Ruffing Tainá Simões , Coelho Fábio Alexandre
Published: May 2024

O objetivo deste artigo é evidenciar a busca pelo reconhecimento do “trabalho invisível das mães no cálculo da pensão alimentícia”, descrevendo o desafio central enfrentado nas interseções do direito de família, justiça social e equidade de gênero com a superação de paradigmas jurídicos e econômicos tradicionais. Estes modelos frequentemente falham em reconhecer e valorizar as contribuições não monetárias para a economia familiar, perpetuando assim desigualdades de gênero estruturais que se manifestam tanto nas esferas privadas quanto públicas da vida. Uma reavaliação conceitual do trabalho doméstico e de cuidado se faz necessária, onde tais atividades sejam compreendidas não apenas como responsabilidades inerentes ou naturais atribuídas às mulheres, mas como contribuições vitais para o sustento e desenvolvimento da sociedade. Essa mudança requer um novo framework (estrutura) jurídico e econômico que considere o trabalho de cuidado como um pilar essencial da economia familiar e, por extensão, da economia nacional. Ademais, o desenvolvimento e a efetivação de metodologias de valoração econômica que possam quantificar de forma justa e precisa o trabalho doméstico emergem como um aspecto essencial nesta discussão. Essas metodologias devem levar em conta não apenas o tempo despendido em tarefas de cuidado e domésticas, mas também o impacto a longo prazo dessas atividades no bem-estar e desenvolvimento dos membros da família. A aplicação dessas metodologias nas decisões relativas à pensão alimentícia poderia proporcionar uma base mais equitativa para a distribuição de recursos após a dissolução conjugal. Estas reformas devem visar à incorporação explícita do valor do trabalho doméstico nas diretrizes de pensão alimentícia, garantindo que os tribunais tenham um mandato claro para reconhecer e compensar as contribuições não monetárias. Além disso, a legislação deve promover uma maior equidade de gênero, desafiando estereótipos e normas sociais que relegam o trabalho de cuidado com os afazeres domésticos ao âmbito feminino. Em suma, o reconhecimento do trabalho invisível das mães no cálculo da pensão alimentícia é uma questão intrinsecamente ligada à justiça social e equidade de gênero, exigindo uma abordagem multidisciplinar que englobe reformas legislativas, desenvolvimento de metodologias econômicas inovadoras, educação e conscientização. Por uma recontextualização do valor do trabalho doméstico, é possível avançar em direção a uma sociedade mais justa e equitativa, onde as contribuições de todas as pessoas são reconhecidas e valorizadas. Este esforço coletivo não apenas beneficiará as famílias diretamente envolvidas, mas também promoverá uma mudança cultural mais ampla, redefinindo o valor do cuidado na construção de uma comunidade resiliente e sustentável.

Based on both the economic and environmental points of view, processing used lithium-ion batteries (LIBs) is of great importance. The valuable components contained in LIB (cathode, anode and current collectors) generate high interest in solving the problem of resource deficiency and reducing environmental destruction due to overexploitation. The starting anode material extracted from a used lithium iron phosphate battery is a mixture of graphite, acetylene carbon black, and polymer binder. Reusing this material in lithium batteries without additional cleaning is impractical owing to poor electrochemical characteristics and the presence of impurities. To achieve effective regeneration, the recycled anode material is first treated in a nitric acid solution to remove copper foil and lithium ions with electrolyte interaction products formed during battery operation. The next step is heat treatment of the material, which allows the removal of acetylene soot and polymer glue binder. The tests showed sufficiently high values of the specific capacity of recycled graphite (~330 mA h g-1 at 0.1 C), which are comparable to commercial materials and meet the requirements of reuse.
The role of autoimmune thyroid disorders in patients with alopecia areata
Authors: Şahin Hatice Nihal , Görgülü Adnan
Published: April 2024

Objective: The aim of this study was to investigate the association of thyroid autoimmunity with alopecia areata (AA) by examining thyroid stimulating hormone (TSH) and thyroid autoantibody levels. In addition, to compare the epidemiologic data obtained with the data of our country.
Methods: Our study was organized as a cross-sectional, retrospective study. The study was performed on patients between the ages of 2-65 years who were admitted to our outpatient clinic between 01.01.2008 and 31.12.2011, who were clinically or histopathological diagnosed with AA, examined for etiology and thyroid autoantibodies were requested. Patients under two years of age and over 65 years of age, patients with no thyroid autoantibodies and pregnant patients were excluded. Results were expressed as mean±standard deviation and median values. Mann-Whitney U test was used to compare TSH, anti-TG antibody (Anti-TG) and anti-TPO (Anti-TPO) antibody values in the variables of nail involvement, psychiatry, comorbidity and family history. Spearman correlation analysis was used to examine the relationships between age and disease duration and TSH, Anti-TPO and Anti-TG variables.
Results: In our study, 65 (42.8%) of 152 patients were female and 87 (57.2%) were male. The ages of the patients ranged between 2-65 years and the mean age was 26.5±14.6 years. The mean age of females was 27.5±14.4 and 25.7±14.9 in males. Elevated thyroid autoantibodies were found in a total of 29 patients, 21 of whom were female and 8 of whom were male. Of these 29 patients, 10 had hypothyroidism, 2 had chronic thyroiditis and 3 had toxic multinodular goiter. 14 patients did not return after the examination at the internal medicine outpatient clinic, so the diagnosis of thyroid disease could not be reached. The mean TSH, Anti-TG and Anti-TPO values were 2.27±1.57, 29.2±99 and 71.5±2.2, respectively. When these values were analyzed separately as men and women, they were found to be 2.6±2.02, 41.8±1.23 and 134±2.8 in women and 1.99±1.03, 19.8±75.6 and 24.5±1.32 in men. There was a significant difference between men and women in terms of Anti-TG and Anti-TPO values (p=0.011 and p=0.001, respectively). A significant correlation was found between disease duration and Anti-TPO positivity (p=0.045); however, a similar relationship was not found between disease duration and Anti-TG positivity (p=0.34).
Conclusions: As a result of this study, although there was a significant correlation between anti-TPO and duration of AA, the association between thyroid autoimmunity and AA was not found to be statistically significant. This may be due to the fact that humoral autoimmunity plays a role in thyroid autoimmunity and primarily cellular autoimmunity plays a role in AA. In addition, the epidemiologic data of our study were similar to the data of studies conducted in our country.

Heat Stress in Indian Mustard (Brassica juncea L.): A Critical Review of Impacts and Adaptation Strategies
Authors: Pillai Anagha J , Walia Puneet
Published: May 2024

Indian mustard, a member of the Brassicaceae family, is a cool-season crop cultivated extensively in various agro-ecological conditions, contributing significantly to vegetable oilseed production. However, being a thermosensitive and C3 plant [1], Indian mustard is highly susceptible to high-temperature stress, particularly during critical developmental stages [2]. High temperatures disrupt physiological, morphological, and biochemical mechanisms essential for plant growth and development. From altered chlorophyll content and osmotic water potential to impaired photosynthesis and reduced seed oil accumulation, heat stress detrimentally affects various aspects of Indian mustard physiology. This comprehensive review examines the impacts of heat stress on Indian mustard, a significant oilseed crop, and explores adaptation strategies to mitigate its adverse effects. Additionally, heat stress during reproductive stages leads to flower abortion, reduced fertility, and poor seed development, significantly impacting yield potential. To cope with heat stress, plant response mechanisms involve intricate signaling pathways, leading to cellular readjustments at transcriptome, epigenome, proteome, and metabolome levels. Breeding approaches, including conventional techniques and advanced molecular tools like CRISPR/Cas-based genome editing, offer promising avenues for developing heat-tolerant cultivars. Integration of multi-omics approaches aids in identifying stress-responsive genes and metabolic pathways crucial for adaptation. Agronomic strategies, such as nutrient management and microbial inoculation, play vital roles in mitigating heat stress effects and enhancing plant resilience. Collaborative efforts and interdisciplinary research are essential to deepen our understanding of heat stress responses and develop sustainable solutions to ensure oilseed crop productivity and food security in the face of climate change. This review underscores the urgency of addressing heat stress challenges in Indian mustard cultivation and highlights the need for concerted efforts to develop effective adaptation strategies for sustainable agriculture.

Authors: Tarek Ahmed Hafez Samah , Ahmed Ibrahim Moawad Mohamed
Published: April 2024

This study examined the relationship between sustainability reports disclosure level and stock price crash risk, as its main goal is to answer the question “what is the relationship between the disclosure level of sustainability reports dimensions (economic, social, and environmental) and the stock price crash risk?” Using a sample of 20 companies listed in the Egyptian sustainability index EGX ESG from 2017 to 2022. The proposed model and hypotheses were analysed using structural equation modelling. The results indicated that there is a statistically significant negative relationship between the disclosure level of all sustainability reports dimensions (economic, social, and environment) and stock price crash risk, as the increase of the level of disclosure in any sector of sustainability reports (economic, social, and environmental) leads to a decrease in the stock price crash risk for the companies in the study sample.

However, the successful implementation of green bonds faces multifaceted challenges, including market dynamics, regulatory frameworks, and the establishment of robust monitoring mechanisms. This research conducts an in-depth exploration of the intricate relationship between green bonds, environmental sustainability, and economic development within the context of Egypt’s Vision. Drawing on a synthesis of academic literature and insights gleaned from international case studies, the study critically evaluates the mechanisms for implementing green bonds. It also identifies the financing challenges and opportunities inherent in Vision green economy aspirations, while proposing strategic pathways to enhance the efficacy of green bond deployment. Formulating a set of research hypotheses, the study examines the alignment of green bond implementation mechanisms with Vision 2030 objectives, evaluates the impact of market perceptions and regulatory frameworks on green bond financing effectiveness, and assesses the role of international collaborations in mitigating financing challenges. Furthermore, the research explores key variables such as environmental impact, green bonds, and financial sustainability to elucidate their interconnections and implications for sustainable development. By offering nuanced insights and actionable recommendations, this research aims to enrich the discourse on sustainable development and financial innovation in Egypt. It seeks to bridge existing knowledge gaps, inform strategic decision-making processes, and facilitate the formulation of evidence-based policies conducive to realizing Egypt’s sustainable development aspirations outlined in Vision 2030.

Does the Audit Going Concern Opinion Really Matter? The Case of Egypt.
Authors: Ramadan Shehata Haitham , N. Ali Abdelwahab
Published: April 2024

The auditor’s going concern opinion (GCO) is an opinion given by an auditor about a firm’s financial health. This opinion serves as an early warning system for the financial distress of client’s firm. The current research aimed to study the impact of the auditor’s going concern opinion (GCO) on stock prices in the Egyptian business environment. On a sample of 132 firms listed on the Egyptian Stock Exchange for the period 2016-2022 with a total of 759 firm-year-observations. In addition to the possible effect of two moderating variables associated with the main independent variables. Which is the expectation of GCO and perceived audit quality (AQ). We added the independent and moderating variables to the modified Ohlsen regression model to test for the value relevance of the GCO, and the effects of the moderating variables on the mentioned above relation. We found no evidence of a significant impact of the auditor’s GCO on the stock prices of companies listed on the Egyptian Stock Exchange, regardless of whether this opinion is expected or not. On the other hand, for the effect of perceived audit quality, we found a significant negative effect of GCO on stock prices for companies being audited by big 4 audit firms, which could be interpreted because of the reputation effect for such firms.

Investigating the Inclusion of Human Rights Education in Pakistani Elite Schools: A Qualitative Content Analysis of History Textbooks
Authors: Rauf Arjumand , Muhammad Yaar , Batool Syeda Beenish
Published: April 2024

Pakistani educational system is broadly divided into public and private sectors. Due to specific financial and administrative issues, the public sector has failed to produce social capital that could serve as an advocate of human rights. However, elite schools in the private sector are better equipped to educate their students on human rights. Through qualitative content analysis, the present study explores the status of human rights in history textbooks taught in elite schools from grade 6 to O-levels and the International Baccalaureate (I.B.) Middle Years Programme (MYP). It was observed that the human rights issues in Pakistan remained part of the null curriculum in the books published for Pakistani students. In the I.B. books, human rights issues were discussed at the global level, leaving elite students ignorant and oblivious to the state of human rights in Pakistan. It is suggested that human rights should be transformed from abstract and generalized statements to absolute and concrete reality, first stemming from local society and then advancing to a global community.
Opportunities for local electric vehicle manufacturing in Africa
Authors: Ibhadode Akii
Published: April 2024

In order to achieve the Sustainable Development Goals (SDG) of the United Nations on Clean Energy, Sustainable Industrialization and Climate Change, there is an urgent call on Africa to decarbonize transportation. Achieving these goals requires that Africa grows its current, largely, non-existent EV fleet to a reasonable level in the near future, to counter harmful emissions from fossil fuel vehicles. This paper discusses the opportunities available to African entrepreneurs on investing in electric vehicle (EV) manufacturing. It also discusses the factors militating against the establishment of a viable automotive sector. To exploit the opportunities offered despite the limitations, the paper advocates a paradigm shift from the conventional vehicle assembly of foreign vehicles to one in which African original designs are made in low-cost, low-volume vehicle manufacturing plants consisting of general-purpose workshop equipment and intensive labour such that the whole value chain for vehicle manufacturing is developed.
The impact of petrol subsidy removal on the adoption of solar power in Nigeria
Authors: Divine Utazi , Stephen Audu , Lanrewaju Soretire , Hillary Ani
Published: April 2024

For decades, the Nigerian government has subsidized the price of petrol, making it one of the lowest in the world. Historically, the country has relied significantly on petrol subsidies to make energy more affordable to its inhabitants. This policy, however, has imposed a significant budgetary burden, fostered smuggling and corruption, and discouraged investment in renewable energy sources. Additionally, it cuts down on the resources that governments may devote to achieving other development goals as well as sustainable development goals. With a growing global emphasis on renewable energy sources and the need to reduce carbon emissions, Nigeria faces the challenge of transitioning from its traditional reliance on fossil fuels to more sustainable alternatives. To determine the impact of petrol subsidy removal on the adoption of solar power in Nigeria, we present a cost analysis comparing the acquisition and operation of a 2.5 kVA solar PV system to that of a petrol generator of the same capacity. The cost analysis shows that the solar PV system is a more cost-effective and sustainable option for power generation than petrol generators, especially in the long term. The paper emphasised the need of harnessing Nigeria's tremendous solar potential and reducing carbon emissions through solar power adoption. The study also shed light on the potential benefits and challenges of promoting solar energy as a viable alternative to traditional electricity supply in Nigeria.
Carbon-neutral aviation in Nigeria: Assessing the feasibility and impacts of sustainable aviation fuel adoption
Authors: Oluwaseun Adeniyi
Published: April 2024

This study investigates the feasibility and potential impacts of transitioning Nigeria's aviation industry towards carbon-neutral operations through the adoption of Sustainable Aviation Fuel (SAF). By examining Nigeria's aviation landscape, international efforts for carbon-neutral aviation, and factors such as feedstock availability, infrastructure, and economic considerations, the paper assesses the viability of SAF adoption. Environmental and economic benefits, including reduced carbon emissions, improved air quality, job creation, and economic diversification, are explored. Challenges such as regulatory hurdles, investment requirements, and public awareness are analyzed, with recommendations provided for policy support, industry collaboration, research and development, and public education campaigns. Despite the absence of specific SAF adoption case studies in Nigeria, insights from international experiences inform the recommendations. The findings suggest Nigeria's potential to lead in SAF adoption regionally, contributing to environmental sustainability and economic growth in the aviation sector, while also offering broader implications for the global industry's transition towards a more sustainable future.
Empowering sustainable mobility in Nigeria: A study of conversion of conventional bicycle to electric bicycle
Authors: Etin-Osa Collins , Etin-Osa Deborah
Published: April 2024

Amid global efforts towards the United Nations Sustainable Development Goals (SDGs), Nigeria's recent decision to eliminate fuel subsidies has amplified the search for sustainable transportation alternatives. In this study, a traditional pedal bicycle was converted into an electric bike (e-bike) in order to explore it as a viable solution to promoting eco-friendly commuting and reducing carbon emissions on Nigerian roads. The conversion cost was 174,500 in Nigerian currency, with the e-bike demonstrating a range of 8.33km per charge, under a load of 136kg on a 36V, 4.8AH battery. At a speed of 15km/h, an estimated 1.44 volts per kilometer were consumed. Notably, the study revealed a 99.49% correlation between voltage depletion and distance covered per kilometer, indicating a highly predictable relationship between energy consumption and travel distance. These insights highlight the e-bike's potential advantages, particularly in terms of cost-effectiveness, presenting a compelling case for the adoption of electric bicycles as a means to decarbonize transportation in Nigeria.
