A Study on Gender Discrimination
Authors: Desai Astha
Published: April 2024

Abstract: Gender discrimination still exists in India, even with significant progress made in certain areas. It can take many different forms, such as unequal access to education, unequal compensation for work of equal value, and deeply rooted cultural customs and practices. Gender-based violence, including domestic abuse and sexual harassment, still affects a lot of women. In addition to experiencing pervasive discrimination, members of the LGBTQ+ community also encounter social and legal obstacles that keep them from exercising their rights and being accepted. Gender discrimination remains a complex issue that is deeply linked with historical and cultural components, necessitating ongoing work towards gender equality, notwithstanding legal initiatives and public awareness campaigns. A new research on gender discrimination among undergraduate students in Bangalore uncovered unsettling trends. The study, which employed surveys and interviews, demonstrates how common genderbased biases and prejudices are among female students in both social and academic contexts. Some of the examples of unjust treatment that female students brought up included less rigorous requirements for their academic accomplishment and less opportunities for leadership positions in student organizations. Furthermore, a large number of female students expressed feeling uncomfortable and unsafe on campus as a result of sexual harassment and gender-based stereotypes. In addition to highlighting the need of combating gender discrimination and advancing inclusivity in educational institutions, this study highlights the need of fostering a friendly and fair learning environment.

Published: April 2024

Abstract: As a consequence of mass unemployment being the byproduct of COVID-19, people around the world discovered investment in cryptocurrency as a means to tackle their declining financial condition. Subsequently, the prominence of Ethereum as a platform for crypto transactions also gave rise to fraudulent transactions. The need to detect these frauds exists even today. This study proposes a token-based approach to detect fraud in Ethereum transactions incorporating the ERC20 standard, by employing machine learning techniques. After cleaning and preprocessing of the dataset, the transaction data was fed to Random Forest (RF), AdaBoost, Extra Trees (ET), Gradient Boosting (GB) and Extreme Gradient Boosting (XGB) classifiers in search of the most suitable model for fraud detection. Meticulous evaluation revealed that RF, ET and XGB classifiers yielded the highest accuracy of 95%. The proposed token-based approach hence presents a novel and efficient solution for fraud detection, with room for improvement and scalability.
Neoextrativismo e construção ‘sustentável’: duas faces do capitalismo financeirizado
Authors: Saramago Rita de Cássia Pereira , Lopes João Marcos de Almeida
Published: April 2024

O presente artigo investiga como o extrativismo, operado nos territórios coloniais, possibilitou a consolidação e a expansão mundial do sistema capitalista, sendo que continua viabilizando-o no presente. Para ilustrar nossos argumentos, usamos o exemplo da mineração. Em seguida, apontamos a cumplicidade existente entre o setor construtivo, em que a Arquitetura é praticada, e o capitalismo exportador de commodities. Indicamos ainda que a crença na ecoeficiência das tecnologias e edificações ‘verdes’, na verdade, mascara a externalização dos danos socioambientais gerados pelos processos de produção hegemônicos – como aqueles que compõem a cadeia produtiva do ferro e do aço (materiais que, em boa parte, empregamos na Construção Civil). Por fim, analisamos o emblemático caso da comunidade de Piquiá de Baixo (MA), em que as problemáticas apresentadas neste trabalho podem ser melhor explicitadas.
From Non-Markovian Dissipation to Spatiotemporal Control of Quantum Nanodevices
Authors: Lacroix Thibaut , Lovett Brendon W. , Chin Alex W.
Published: April 2024

Nanodevices exploiting quantum effects are critically important elements of future quantum technologies (QT), but their real-world performance is strongly limited by decoherence arising from local `environmental' interactions. Compounding this, as devices become more complex, i.e. contain multiple functional units, the `local' environments begin to overlap, creating the possibility of environmentally mediated decoherence phenomena on new time-and-length scales. Such complex and inherently non-Markovian dynamics could present a challenge for scaling up QT, but – on the other hand – the ability of environments to transfer `signals' and energy might also enable sophisticated spatiotemporal coordination of inter-component processes, as is suggested to happen in biological nanomachines, like enzymes and photosynthetic proteins. Exploiting numerically exact many body methods (tensor networks) we study a fully quantum model that allows us to explore how propagating environmental dynamics can instigate and direct the evolution of spatially remote, non-interacting quantum systems. We demonstrate how energy dissipated into the environment can be remotely harvested to create transient excited/reactive states, and also identify how reorganisation triggered by system excitation can qualitatively and reversibly alter the `downstream' kinetics of a `functional' quantum system. With access to complete system-environment wave functions, we elucidate the microscopic processes underlying these phenomena, providing new insight into how they could be exploited for energy efficient quantum devices.

Published: April 2024

Each teacher must be able to harmonize the assessment of cognitive and psychomotor aspects with the assessment of students' affective aspects in learning. Most of the research conducted in Aceh is still limited to the development of spiritual attitude assessment instruments, while studies describing the ability of science teachers to design spiritual attitude assessment instruments are still very limited. This study aims to determine the ability of junior high school science teachers in the Pidie District to prepare questions to measure students' spiritual attitudes. The research uses the Mix method, with documentation and interview analysis techniques using the Miles and Huberman models, and the feasibility validity of the spiritual attitude assessment instrument uses a Likert scale and is then presented using percentage calculations. A purposive sampling technique is applied in determining the sample. The results showed that most of the teachers had less ability to design spiritual attitude assessment instruments. Few teachers could compile a comprehensive spiritual attitude assessment instrument per the attitude assessment technique in the 2013 curriculum. The first obstacle science teachers faced was formulating assessment indicators, where some teachers did not understand spiritual attitudes with social attitudes in learning. Secondly, assessment techniques with Rubik's or scoring guidelines were not in line with the demands of the 2013 curriculum.

Herein, we synthesized two small molecules named as 4TBTCN and 6TBTCN
with strongly electron-rich 4T and 6T as central unit and weak
electron-withdrawing benzo[c][1,2,5]thiadiazole-4-carbonitrile
as termini, which were connected by C-C single bond. Both mole-cules
exhibited medium optical bandgap and high-lying frontier molecular
orbital energy levels, which were matched with those of the
representative low-cost polymer donor P3HT. Moreover, 4TBTCN and 6TBTCN
showed high stability under continuous illumination and base condition,
owing to a lack of exocyclic vinyl group between the central unit and
end group. Compared to P3HT:6TBTCN, P3HT:4TBTCN blend system displayed
lower miscibility and thus more distinct phase separation, leading to
more efficient charge transport and collection. Although the LUMO energy
level of 4TBTCN was 0.15 eV deeper than that of 6TBTCN, the energy loss
for P3HT:4TBTCN based device was similar to that of P3HT:6TBTCN based
device. As a result, P3HT:4TBTCN based device displayed a similar
open-circuit voltage but higher fill factor and short-circuit current
density, yielding a superior power conversion efficiency, in comparison
to P3HT:6TBTCN based device. This work provides a new strategy for
design of efficient and stable acceptor molecules.

Published: April 2024

Aim: The aim of the research was to find the advantages and disadvantages of running care farms, one of the forms of entrepreneurship in rural areas that drive social innovation. Methods: The study’s analyses consisted of secondary research and a qualitative approach. The target group reached were people interested in or already running care farms in Poland (n = 17). The research was conducted between December 2022 and March 2023. Results: The findings reveal the observed advantages and disadvantages of care farms as reported by those overseeing these centers. Operators of such facilities emphasize the importance of their centers being part of a network of similar entities. Conclusions: The most important conclusions were the need for further regulation to help social farming actors stay in business through networking, better marketing and advertising of social farming operators that support the local community, creating jobs, and improving the quality of life of those in need.
THE IMPACT OF TRADE LIBERALIZATION ON THE PERFORMANCE OF TANZANIA’S EXPORT SECTOR – A TIME SERIES ANALYSIS FROM 1980 TO 2019
Authors: Utouh Harold
Published: April 2024

Aim: This article aims to enhance understanding of the impact of trade liberalization on Tanzania’s export performance. As many studies conducted, both in developing and developed countries, have yielded mixed results and the relationship varies across different nations, it is difficult to provide a definitive answer to the question of whether trade liberalization affects Tanzania’s export sector without first conducting an empirical analysis. Methods: This study employs a quantitative research methodology because it allows for a larger sample size, greater objectivity, and accuracy. Due to the nature of the study and the data used, a statistical study design was chosen. Macroeconomic data spanning 1980 to 2019 was obtained from the World Bank and the Tanzania Bureau of Statistics to analyze the effects of trade liberalization on export performance using vector error correction and autoregressive distributed lag models. Results: The results reveal a sig­nificant positive correlation between trade liberalization and subsequent export performance, as well as the interdependencies between trade liberalization and foreign direct investment (FDI) strategies. There is a re­ciprocal relationship between trade liberalization and exchange rates, implying the significance of competent exchange rate management in enhancing export competitiveness. Conclusions: The study concludes that trade liberalization, FDI, and export performance have a long-term positive correlation. This implies that a carefully executed trade liberalization policy is crucial not only for the expansion of the export industry sector and the influx of capital, but also for the transformation and development of the nation.growth.

Review on Toxicity, Mechanisms and Health Effects of Herbicides and Prevention Mechanisms
Authors: D Abera
Published: April 2024

In agricultural crop production, herbicides are typically used to prevent or control weeds and other plant pathogens by reducing crop losses and maintaining high product quality. This brief overview sheds light on the level of toxicity, mechanisms of toxicity, health effects and prevention strategies. Three main levels of toxicity have been identified in herbicides: acute (short-term exposure), sub-chronic (medium-term exposure), and chronic (long-term exposure). These levels of toxicity have detrimental effects on humans, animals, and the environment. Herbicides must be handled and administered appropriately to minimize or completely prevent their negative side effects. It is recommended to manage herbicide to its minimum residue level while using them in agriculture. On the hand, certain mechanisms of action must be followed including contact, absorption, movement, toxicity, and death in order to be effective in management of weed by herbicides. This mechanism of actions of herbicides are also applied to humans and animals too. Improper usage of herbicides has adverse health effects on humans such as carcinogenic, cardiovascular, respiratory, hormonal, metabolic, cellular and neurological effects. In order to eliminate or minimize their effect the preventive safety mechanisms/strategies such as employing alternative and less herbicide-dependent cropping systems, properly using all certified personal protective equipment (PPE), proper packaging and package leaflet, proper labeling and giving general awareness about the use or handle of herbicide for farmers or any others who are not familiar with the use of herbicides must applied before or after handling of herbicides. In order to minimize or totally avoid the negative impacts of herbicides on humans, animals, and the environment, it is not just the responsibility of farmers but also of other stakeholders (agricultural experts, policymakers, etc.).
