Facies models for rocky shorelines and their application to transgressed basement highs in the North Sea.
Authors: Puig Lopez Josep Maria , Howell John
Published: January 2024

Rocky shorelines form where basement highs are eroded and flooded during marine transgressive events. Despite the Mesozoic North Sea rift generated numerous platform margins and rotated fault blocks which acted as basement highs, rocky shoreline deposits have not been previously reported. In the rock record rocky shoreline deposits are usually represented by thin conglomerates overlying major unconformities, and are typically characterised by their ichnological aspects, rather than their depositional facies. This study uses the sedimentological aspects of modern and Miocene rocky shoreline conglomerates from Spain and Austria, to create facies models which are then applied to the recognition of rocky shorelines in the Mesozoic of the Central North Sea. Our results demonstrate that structureless, clast-supported, poorly-to-moderately sorted conglomerate deposits are associated with competent basement lithologies, which produce hard, resistant coastal cliffs in areas associated with volcanic centres which were previously overlooked in the subsurface. The basement lithologies in most of the Central North Sea favoured the formation of smaller coastal cliffs, with less resistant lithologies that did not generate or preserve gravel size particles, precluding the preservation of Mesozoic rocky shores in much of the North Sea’s stratigraphic record.

Published: January 2024

The Mnemonic Similarity Task (MST; [1]) is a widely used measure of individual tendency to discern small differences between remembered and presently presented stimuli.Significant work has established this measure as a reliable index of neurological and cognitive dysfunction and decline. However, questions remain about the neural and psychological mechanisms that support performance in the task. Here, we provide new insights intothese questions by fitting seven previously-collected MST datasets (total N = 529) usinga three-choice evidence accumulation model (the Linear Ballistic Accumulator; LBA [2]).The model decomposes choices into automatic and deliberative components. We showthat these decomposed processes both contribute to the standard measure of behavior in this task, as well as capturing individual variation in this measure across the lifespan.We also exploit a delayed test/re-test manipulation in one of the experiments to show that model parameters exhibit improved stability, relative to the standard metric, acrossa one week delay. Finally, we apply the model to a resting-state fMRI dataset [3], findingthat only the deliberative component corresponds to off-task co-activation in networks associated with long-term, episodic memory. Taken together, these findings establish a novel mechanistic decomposition of MST behavior, and help to constrain theories about the cognitive processes that support performance in the task.
Policy Shaping the Impact of Open-Access Publications: A Longitudinal Assessment
Authors: Hadad Shlomit , Aharony Noa , Raban Daphne R.
Published: January 2024

This study investigated the longitudinal impact of Open-Access (OA) publication in Israel, a country which has not yet adopted a formal OA policy. We analyzed bibliometric indicators of Israeli researchers across all academic disciplines, focusing on OA publications published in journals and repositories from 2010 to 2020. Data extracted from Scopus reveal a consistent "OA citation advantage" (OACA) throughout the study period, suggesting the influence of OA publication on citation rates beyond time and scientific novelty. Despite the highest number of publications in the green route, steadily increasing over the years, and a recent rise in gold route publications, the hybrid route demonstrates a significantly higher citation advantage, highlighting an "OA subtype citation effect". Furthermore, our study uncovers a "funding effect" on OA grant-funded publications, indicating a doubled likelihood of publishing in OA when research is funded, contingent on the funder's OA policy. The findings offer comprehensive insights into OA publishing trends in Israel, serving as a case study for assessing the impact of OA policy. The study underscores the importance of both funder-specific OA policies and broader initiatives by the global scientific community and intergovernmental organizations to promote OA publishing and address potential disparities in research dissemination. Efforts to combat the "rich get richer" effect can foster equitable access to scientific knowledge.

Does Microfinance Affect Women Empowerment? Evidence from Rautahat District of Nepal
Authors: Thapa Bharat Singh , Amit Yadav
Published: January 2024

The issue of women empowerment is a significant focus in developing countries as it has a high potential for poverty reduction and overall development. Microfinance institutions (MFIs) have emerged as potential instruments for addressing both poverty and women's empowerment. This study investigated the connection between microfinance and women's empowerment in rural Nepal. Through a survey among 150 women clients of MFIs in Rautahat district, the study analyzed how social empowerment of women changes after participation is microfinance programs. Employing hypotheses testing with statistical tests like the Wilcoxon Signed Rank Test and One-sample t-test, the study found compelling evidence of a positive influence of microfinance on women's empowerment. After participation in microfinance programs, women's status was found significantly increased in terms of ownership in assets, decision-making autonomy, freedom of mobility and social recognition. These findings suggest that microfinance can be a valuable tool for empowering women in developing countries, potentially leading to improved social well-being, and increased participation in community decision-making. However, further research is needed to understand the long-term sustainability of these impacts and address potential challenges such as debt burden and social stigma associated with borrowing.
Impact of Credit Risk and Macroeconomic Variables on the Profitability of Commercial Banks in Nepal
Authors: Niraula Damodar , Maharjan Sujita
Published: January 2024

This study was conducted to examine the impact of credit risk and macroeconomic variables on the profitability of commercial banks in Nepal. Return on assets and earnings per share of the banks were taken as regrassands. Whereas, as regressors, non-performing loan, capital adequacy ratio and credit to deposit ratio were taken as the proxies of credit risk, and GDP growth rate, consumer price index and base rate were studied as indicators of macroeconomic variables. Following simple random sampling techniques, 14 commercial banks were selected as sample for the study. The required quantitative data were retrived from annual financial reports of the banks. Data were analyzed on Gretl software. The Pearson correlation and Ordinary Lease Square model for regression resulted that the GDP growth rate was insignificant in defining the variation on return on assets. Likely, inflation and base rate were not significant in defining the variation on earning per share. Result of this study provided sufficient scope to bankers in developing their growth strategies.
Impact of Strategic Human Resource Management Practices on Employee Retention
Authors: Shrestha Prakash , Prajapati Mamata
Published: January 2024

This paper aims to analyze the impact of strategic human resource management (SHRM) practices on employee retention. This study employed a quantitative research approach. Senior-level people including CEOs, DCEOs, general managers, operation in-charges, HR managers, and branch managers of six commercial banks and six insurance companies were requested to respond to a series of questionnaires to collect data. 240 questionnaires were distributed; 167 questionnaires (69.58%) were returned and used for analysis. The results suggest that the banks and insurance companies in Nepal might retain their workforces in part by implementing SHRM practices. Out of five indicators of SHRM practices only three indicators such as recruitment and selection, compensation and benefits, and career management practices have a significant and positive impact on employee retention, whereas two indicators such as training and performance appraisal practices have a negative impact on employee retention. In fact, employee retention is the main problem that Nepalese commercial banks and insurance are facing. This is due to high employee turnover. Therefore, they need to focus on employee retention through the effective application of SHRM practices. They also need to create a cohesive set of employment policies to attract and retain skilled employees.

Among five factors, the market risk premium found to be the most prominent factor affecting stock returns.
Learning English Through Non-English Subjects: A Survey on Nepalese EFL Students
Authors: Wagle Bashu Dev
Published: January 2024

In Nepal, students are taught various subjects using two different mediums of instruction. The majority of teachers prefer using English as the medium of instruction, but there are still some who opt for their mother tongue. This research aimed to investigate the impact of teaching English through non-English subjects on the vocabulary development of Nepalese EFL students. A total of seventy-four students participated in this study and were divided into two groups: one group learned English through non-English subjects (SLETNES) as the experimental group, while the other group learned non-English subjects in their mother tongue (SLNESMT) as the control group, based on teachers’ preferences for the medium of instruction. Both groups of students completed a questionnaire, and the data collected were analyzed to determine which group exhibited better vocabulary learning outcomes. The study spanned four sessions, with each session lasting 40 minutes. The data analysis revealed a significant difference between the two groups, with SLETNES students being exposed to a more extensive vocabulary.

Authors: Carroll Amanda , Kirchen Twylla
Published: January 2024

LAY SUMMARY

This qualitative study explored the experiences of older U.S. women Veterans regarding their experiences and perceptions of their time in military service and its overall impact on their lives. Five women Veterans participated in interviews that were analyzed and resulted in four main themes: 1) family military history, 2) being treated differently and proving themselves, 3) making the most of opportunities, and 4) lasting personal strengths. Findings from this study highlight how, despite enduring negative experiences during military service because of gender, participants credited the military with having an overall positive impact on their lives in the long term. This study suggests that health care interventions and services that tap into positive aspects of military service, as identified by older women Veterans (i.e., personal strengths such as resilience and pride), may have the potential to promote the health and well-being of this population.

A rubber compound is an intermediate product resulting from mixing rubber with other additives before being molded through a vulcanization process. Frequently, there is a delay between the compounding process and vulcanization, therefore proper storage procedures must be prepared. The presence of a vulcanizing agent, activator, and accelerator in the compound allows the vulcanization reaction to occur during the storage period. This study aims to analyze the effect of the storage time and temperature of rubber compounds on rubber vulcanization characteristics. The rubber compound is stored at room temperatures of 25oC and 32oC. On the 1st, 3rd, and 5th day of storage, the compounds were tested using a rheometer to obtain vulcanization parameter data. The values of MH, ML, ts2, tc90, cure rate index (CRI), and effective torque of each treatment were studied. The results showed that the storage time of the compound affected each of the observed parameters. In the range of 5 days, the longer time indicates the formation of polysulfide crosslinks in the rubber polymer chain network. Higher storage temperature also faster reaction rate during storage. The increasing number of cross-links resulting a longer induction period dan vulcanization time, lower CRI, and effective torque.

Purifying Crude Glycerol from Biodiesel Production for Sustainable Energy Solutions
Authors: Rahman Herliati
Published: January 2024

Biodiesel production has been an important part of a global effort to replace fossil fuels with renewable energy sources. However, one of the problems facing biodiesel production is increased production of glycerol as a by-product. Glycerol, or crude glycerol (CG), is generally produced in significant quantities and needs to be managed wisely. This article discusses the potential use of glycerol from biodiesel production as a raw material for bioethanol production. By optimizing fermentation processes, genetic engineering technology, and purification, glycerol can be converted into bioethanol, one of the more environmentally friendly renewable fuels. The success of the conversion of glycerol to bioethanol is also supported by advances in genetic engineering technology that enable the development of more efficient and productive microorganisms. This creates great opportunities to reduce waste, support resource sustainability, and reduce dependence on fossil fuels through the use of glycerol as a bioethanol raw material. Conversion of glycerol to bioethanol is a step towards more sustainable and environmentally friendly renewable energy.

Published: January 2024

Este artigo apresenta uma análise de revistas de histórias em quadrinhos de grande circulação no Brasil e no exterior, destacando os elementos científicos presentes nessas publicações que podem ser utilizados como formas de ensino não formal. Para isso, foram examinadas 33 revistas do tipo almanaque da Mônica no período de 2009 a 2020. Não foram analisados exemplares dos anos de 2015 e 2016, pois não havia exemplares gratuitos e as pesquisadoras não os possuíam em seu acervo. Os números disponíveis foram organizados em categorias de acordo com características semelhantes. Foi possível constatar que, mesmo sem a intenção explícita de ensinar, a maioria das revistas continham histórias que incorporaram apenas conceitos científicos nas temáticas da revista, no entanto, fazem de maneira equivocada e perpetuam com uma visão tecnicista da ciência e masculina de cientista. Como proposta, este trabalho apresenta possíveis formas de utilização dos episódios selecionados em sala de aula, além de reflexões sobre o impacto de alguns elementos na divulgação da ciência.

Published: January 2024

O objetivo desta investigação foi compreender como as atividades investigativas podem auxiliar os alunos a superarem suas concepções errôneas em relação à Natureza, Propagação e Qualidades do Som. Para tanto, foi elaborada e aplicada uma Sequência de Ensino Investigativa (SEI) com foco em experimentos. Esta pesquisa teve caráter misto e delineamento quase-experimental, fazendo-se uso de grupos controle e experimental. Os dados foram coletados a partir de um questionário, aplicado tanto no pré-teste quanto no pós-teste. Como métricas de análise, foram utilizados o ganho normalizado de aprendizagem (g) e o tamanho do efeito (d de Cohen). Os resultados mostram maior ganho de aprendizagem na turma que recebeu a SEI em comparação com a que não recebeu, sendo verificado ainda um efeito muito grande da SEI nesta turma. Tais resultados permitem inferir que os alunos da turma experimental possivelmente superaram mais suas concepções errôneas em relação à turma controle.
A ALQUIMIA NOS LIVROS DIDÁTICOS DE QUÍMICA APROVADOS PELO PROGRAMA NACIONAL DO LIVRO DIDÁTICO

Published: January 2024

Considerando a importância da Alquimia e seu contexto histórico, a presente pesquisa teve como objetivo compreender como a Alquimia é explorada nas obras didáticas aprovadas pelo Programa Nacional do Livro Didático (PNLD) de 2018. Trata-se de uma pesquisa de natureza qualitativa. Para análise dos livros didáticos, utilizamos como critério as marcas da historiografia tradicional apontadas por Beltran, Saito e Trindade (2014), e os livros didáticos foram identificados pelas letras LD, seguidas por um código numérico: LD1, LD2, LD3, LD4, LD5, LD6. Pela análise dos livros didáticos, identificaram-se características da perspectiva historiográfica tradicional, consideradas ultrapassadas por Beltran, Saito e Trindade (2014), o que evidencia que, de modo geral, não há importante valorização da nova historiografia da ciência. Verificou-se que, em LD4, a Alquimia não é contemplada em nenhum dos capítulos, enquanto que apenas LD5 apresenta poucos aspectos da antiga historiografia, evidenciando que os autores buscaram inserir a nova historiografia da ciência em sua abordagem. De modo geral, os livros didáticos analisados fazem uma abordagem da Alquimia que carece de informações históricas e ainda é permeada por aspectos da antiga historiografia da ciência.

Este trabalho é um relato de experiência que teve como objetivo elaborar um instrumento para o ensino de física, desenvolvido por licenciandos em Física de uma universidade pública na disciplina de Instrumentação para o Ensino de Ciências. O trabalho se justifica na medida que o ensino de Física baseado unicamente em aulas expositivas não garante que os estudantes desenvolvam os subsídios cognitivos necessários para a aprendizagem, reforçando a necessidade de que o ensino baseado unicamente na transmissão precisa ser superado. Portanto, neste trabalho foi construída uma História em Quadrinhos tendo como tema a acústica, o uso desse recurso visa desenvolver o interesse dos alunos e permitir o seu protagonismo em seu processo de aprendizagem. A HQ foi desenvolvida no software Inkscape, que é um editor de gráficos vetoriais de qualidade profissional para Linux, Windows e MacOS, sendo gratuito e de código aberto. Além de elaborado e impresso o recurso, socializamos o processo de construção em um minicurso destinado a professores e estudantes da área do ensino de ciências. Como objeto de análise consideramos tanto o processo de elaboração do instrumento, quanto o processo de socialização deste no minicurso, a partir da observação e notas tomadas nesse encaminhamento. Nossos resultados indicam que esse instrumento pode favorecer ao leitor e ao professor, um amplo leque de ações cognitivas, como análise, interpretação, imaginação, favorecendo a contextualização da física, ou seja, dos conceitos de acústica e situações vivenciadas no cotidiano.

Published: January 2024

Neste relato de experiência, destacaram-se as percepções adquiridas durante a realização do Estágio Supervisionado em Ciências, conduzido em uma instituição de ensino na modalidade de Educação de Jovens e Adultos (EJA). O propósito do estágio consistiu em alcançar uma compreensão prática do ambiente de docência, bem como das complexidades inerentes à profissão docente. O cerne deste artigo reside na análise da metodologia subjacente ao projeto de intervenção didática, que foi desenvolvido e implementado durante o estágio. Paralelamente, foram discutidos os obstáculos identificados no processo de concretização desse projeto, delineando possíveis justificativas para os desfechos observados. Adicionalmente, abordaram-se os aspectos sociopolíticos que permeiam a modalidade EJA, realçando a relevância do estágio curricular no âmbito da formação de licenciandos.

Authors: Foss De Zorzi Fernanda Cristina , Copetti Jaqueline
Published: January 2024

A adolescência constitui-se em uma fase com diversas alterações, essas quando observadas durante o processo de problematização, elaboração e implementação de políticas públicas podem influenciar na qualidade de vida do adolescente. O objetivo foi analisar estudos referentes às políticas de educação e saúde que gerem reflexos para a qualidade de vida do aluno adolescente. A metodologia utilizada foi uma revisão bibliográfica narrativa. Como resultados  destaca-se o Programa Saúde na Escola (PSE) com potencialidade de promover qualidade de vida ao aluno adolescente; a necessidade de inserção do tema transversal relacionado à saúde no currículo escolar e o desenvolvimento deste de forma interdisciplinar, pautado na realidade do aluno adolescente; a necessidade do planejamento integrado dos setores da educação e saúde;  a formação de rede de apoio para promoção da saúde refletindo no desenvolvimento de um cidadão responsável com hábitos de vida saudáveis e capaz de mudar o contexto em que vive. Um aspecto com destaque nos textos analisados é o desconhecimento dos profissionais da educação, da saúde e dos gestores dessas, sobre os objetivos e diretrizes das políticas estudadas. Fato que pode influenciar na efetividade de tais políticas em relação ao reflexo sobre a qualidade de vida do aluno adolescente.

No cenário das políticas educacionais curriculares brasileiras a Base Nacional Comum Curricular é uma questão recente. Considerando essa problemática é de suma importância que esse campo seja explorado com pesquisas abordando o seu contexto de elaboração e efetivação, além disso em se tratando de BNCC do Ensino Médio esse tema torna-se mais ainda hodierno dado que essa etapa de ensino está passando por uma grande reforma curricular. Diante desse cenário, o objetivo desta pesquisa é analisar a proposta de ensino presente no texto referente a área de Ciências da Natureza e suas tecnologias apresentado na versão atual da BNCC do Ensino Médio. Para isso, realizou-se uma pesquisa qualitativa, de caráter exploratório, tendo como forma de coleta de dados a pesquisa bibliográfica e documental. Ao final constatou-se que, de modo geral, apesar do texto da BNCC remeter para um ensino interdisciplinar entre as disciplinas Física, Química e Biologia e também outras áreas do conhecimento, muitos temas importantes para a área foram silenciados ou reduzidos do referido documento.
