Authors: Reis Anne Vitoria Dornelas , Silva Giovana Bachmann da , Costa Yasmim Melissa Soares da
Published: February 2025

A revista “Meninas e Mulheres na Ciência: Publicações Pesquisa para Elas 2024 – Volume 1” é mais do que uma compilação de pesquisas científicas; é um manifesto em prol da equidade de gênero nas áreas de STEAM (Ciência, Tecnologia, Engenharia, Artes e Matemática). Esta obra reúne os frutos do trabalho de meninas do ensino médio e graduandas, desenvolvidos em colaboração com suas orientadoras de instituições de renome nacional e internacional. O Programa Pesquisa para Elas, uma iniciativa da ONG STEM para as Minas, foi criado em 2021 como resposta à escassez de oportunidades científicas para meninas no Brasil. De acordo com o Centro de Pesquisa em Ciência, Tecnologia e Sociedade do IPEA, as mulheres cientistas representam apenas 14% dos membros da Academia Brasileira de Ciências, e a sub-representação feminina em cargos de liderança científica persiste, mesmo sendo a maioria entre os doutorandos. Com base nesses dados alarmantes, o programa visa abrir portas para meninas de escolas públicas e de faculdades que, de outra forma, talvez não tivessem a chance de experimentar a pesquisa científica de perto. Nesta obra, composta por vinte e dois capítulos, exploramos temas que atravessam as grandes áreas de STEAM: Ciências Biológicas, Tecnologia e Engenharia, Ciências Humanas, Ciências Naturais e da Terra, e Ciências Exatas. Os trabalhos apresentados abordam questões como tecnologias assistivas, saúde mental, inteligência artificial e economia, mostrando a vasta gama de talentos e interesses de nossas jovens pesquisadoras.

Published: February 2025

The purpose of the study was to investigate the use of Information and Communication Technology (ICT) in the teaching of Religious and Moral Education (RME) in basic schools in Cape Coast. It sought to establish RME teachers’ levels of perceived ease of use (PEU) and perceived usefulness (PU) of Information and Communication Technology, as well as determine the effect they have on RME teachers’ actual use (AU) of ICT. The Technology Acceptance Model was the undergirding theory for the study. The Cross-sectional survey design was used. All 150 RME teachers and 950 Basic 8 and 9 students of basic schools in the Cape Coast metropolis constituted the population of the study. Using proportionate simple random sampling procedure, a sample of 121 teachers and 561 students was obtained. Data was collected using two sets of structured questionnaires and analyzed descriptively using frequencies, percentages, mean, and standard deviation, as well as inferentially using simple linear regression. Results revealed that RME teachers have a high level of PU, PEU and AU of ICT in the teaching of RME. The regression analysis portrayed that PU of ICT moderately explains 51% of the variance in the AU of ICT in teaching RME, and PEU of ICT explains 39% of the variance in the AU of ICT. It is obvious from the findings that the usefulness and easy operation of ICT tools would lead to their use by RME teachers. To deal with this issue, the study recommended that the National Council for Curriculum and Assessment and Ghana Education Service should continue to enhance ICT training programmes for RME teachers. To address the limited knowledge about ICT among RME teachers, teacher development workshops and seminars that target comprehensive ICT training should be organised for RME teachers.

Published: February 2025

This paper looks at the role of games in teaching grammar to teenagers. The goal is to find out how students feel about gamification in educational settings and investigate how it affects grammatical abilities when used in grammar instruction. Gamification is using games for a specific purpose, such as teaching grammar to pupils. It goes beyond simply employing games for this reason. 10th grade were chosen as the participants of this research. There were two groups: experimental and controlled. The present study was built on three experimental stages: pre-test, interventions, and post-test with a questionnaire. During the pre-experimental stage, both groups were conducted a pre-test which contained 20 multiple-choice questions. Students’ achievements in both groups were similar to each other. Then, students from the experimental group were taught grammar by using three games. By the end, two groups had post-tests and a questionnaire was taken from the experimental group. With the help of pre-test and post-test, the differences were defined. Students from the experimental group showed higher results compared to the control group. The data analyses, based on a questionnaire, prove that learners from the experimental group had positive perceptions about the games. Furthermore, fun and enjoyment make students stay motivated to learn new grammar.

Published: February 2025

The article presents the results of a study analysing the compliance of the content of educational programs in pedagogical universities for primary school teacher training with the norms of the Professional Standard for Teachers. The research aimed to identify «problem areas» in the content of teacher training educational programs and develop recommendations for stakeholders on improving continuous pedagogical education. A quantitative content analysis method was applied to analyse the programs. Based on the teacher standard competency framework, a table of frequency factors for compliance was developed. Using this research tool, educational programs from national, and regional universities, and a pedagogical institute in a monocity were studied. The study has limitations regarding the testing of a single assessment tool and the number of programs presented. The research results indicated that the program from the national university had the highest compliance with the teacher standard norms. Moreover, knowledge components significantly dominate educational programs. The content of educational programs revealed that professional teaching and development competencies of teachers have low-frequency indicators according to the Professional Standard norms. Based on the data obtained, recommendations were developed for stakeholders to further improve continuous pedagogical education.

The effect of carbonate mineral additions on biogeochemical conditions in surface sediments and benthic–pelagic exchange fluxes
Authors: Biçe Kadir , Myers Stewart Tristen , Waldbusser George G. , Meile Christof
Published: February 2025

Abstract. Coastal sediments are hotspots of biogeochemical processes that are impacting subsurface and overlying water conditions. Fluid composition in sediments is altered through the mineralization of organic matter which, under oxic conditions, further lowers both pH and the carbonate saturation state. As a potential mitigation strategy for this sediment acidification, we explored the effects of mineral additions to coastal sediments. We experimentally quantified carbonate mineral dissolution kinetics of carbonate shells suitable for field application and then integrated these data into a reactive transport model that represents early diagenetic cycling of C, O, N, S, and Fe and traces total alkalinity, pH, and saturation state of CaCO3. Model simulations were carried out to delineate the impact of mineral type and amount added, porewater mixing, and organic matter mineralization rates on sediment alkalinity and its flux to the overlying water. Model results showed that the added minerals undergo initial rapid dissolution and generate saturated conditions demonstrating the potential of alkalinity enhancement in mitigating surface sediment acidification. Aragonite dissolution led to higher total alkalinity concentrations than calcite. Simulations of carbonate mineral additions to sediment environments with low rates of organic matter mineralization exhibited a substantial increase in mineral saturation state compared to sediments with high CO2 production rates, highlighting the environment-specific extent of the effect of mineral addition. Our work indicates that carbonate additions have the potential to effectively buffer surficial sediments over multiple years, yielding biogeochemical conditions that counteract the detrimental effect of low-pH sediment conditions on larval recruitment and potentially increase benthic alkalinity fluxes to support marine carbon dioxide removal (mCDR) in the overlying water.

Abstract. Satellite-driven inversions provide valuable information about methane (CH4) fluxes, but the assimilation of total column-averaged dry-air mole fractions of CH4 (XCH4) has been challenging. This study explores, for the first time, the potential of the new lower tropospheric partial column (pXCH4_LT) GOSAT data, retrieved by the Japan Aerospace Exploration Agency (JAXA), to constrain global and regional CH4 fluxes. Using the CarbonTracker Europe-CH4 atmospheric inverse model, we estimated CH4 fluxes between 2016–2019 by assimilating the JAXA/GOSAT pXCH4_LT and XCH4 data and surface CH4 observations, independently of each other. The Northern Hemisphere CH4 fluxes derived from the JAXA/GOSAT pXCH4_LT data were similar to the estimates derived from the surface observations, but was underestimated by about 35 Tg CH4 year-1 (∼6 % of the global total) using the JAXA/GOSAT XCH4 data. For the Southern Hemisphere, the estimates from the both GOSAT inversions were about 15–30 Tg CH4 year-1 higher than that derived from surface data. The evaluations against independent data from the Atmospheric Tomography Mission aircraft campaign showed good agreement in the lower tropospheric CH4 from the inversions using the JAXA/GOSAT pXCH4_LT and surface data. However, the modelled North-South gradients showed significant overestimation in the upper troposphere and stratosphere, possibly due to relatively uniform inter-hemispheric OH distributions that control CH4 sinks. Overall, we found that the use of the JAXA/GOSAT pXCH4_LT data shows considerable potential in constraining global and regional CH4 fluxes, advancing our understanding of the CH4 budget.

Abstract. The development and evolution of satellite altimetry and operational oceanography are very closely linked. By providing all weather, global and real time observations of sea level, a key variable to constrain ocean analysis and forecasting systems, satellite altimetry has had a profound impact on the development of operational oceanography. Over the past 20 years, satellite altimetry has been providing a continuous observation of the ocean in near real time. From the launch of Jason-1 in 2001 to the launch of SWOT in 2022, satellite altimetry capabilities have regularly improved from geophysical corrections, processing algorithms including real time processing, altimeter radar technology (SAR mode, swath altimetry) and resolution thanks to the use of multiple altimeters and now swath altimetry. In parallel, major improvements of ocean prediction systems have occurred from the GODAE demonstration in the 2000s up to fully operational systems serving now a large range of applications in the 2020s. The paper provides an overview of the development and evolution of satellite altimetry and operational oceanography over the past 20 years in the context of the Mercator Ocean prediction center, the DUACS system and the EU Copernicus Marine Service. Impact of altimetry on the performances of ocean prediction systems (based on OSEs and OSSEs) is reviewed. The future contribution of swath altimetry on operational altimeter products and ocean prediction is also discussed. Prospects for the next decade are discussed in conclusion.

Published: February 2025

This essay includes collated contributions from practising writers, participants in a Creative Writing|Neuroimaging Exploratory Study, Ideasthetic Imagining – Mapping the Brain’s Microstates Using Magnetoencephalography (MEG), conducted at Swinburne University (2023, Melbourne, Australia). The study investigates neural activity in participants’ brains while undertaking a creative writing workshop. Participants write imaginatively from short and long-term memory. The research team utilises MEG neuroimaging technology to determine where and how the brain is processing information at distinct stages of the workshop. The creative writing workshop at the heart of the study involves imaginative approaches to life writing, transforming unresolved memories through creative practice. As participants engage in the workshop, the research team measures activity in target regions of the brain. The researchers then analyse the interaction between distinct regions of the brain at various stages. The following essay gathers the voices of the experimental group (practising writers), asking them to reflect upon their experience of writing a long-term memory, as they experienced it at the time and, subsequently, from a perspective other than their own. In this exercise, particular regions of the brain are activated (to a far greater extent) in the experimental group (practising writers) as opposed to the control group (non- writers).

The research aim is to see how Country speaks and what it says, which includes what it says through the cultural productions of Barkindji and other people in town. We are using a mass-media setting and technology – radio, and now print – to discuss and send out messages about Barkindjiness, Country, history and modernity. It’s about using the master’s tools to dismantle the master’s preconceptions. By bringing poets Jen Crawford and Paul Magee into the discussion and space, we are investigating communication between Barkindji Country and Barkindji people with white society. The discussion was broadcast live.
“Some harm, some foul”: The editor’s duty of care in minimising the potential harm of creative nonfiction that contains problematic or distressing material

Published: February 2025

The popular Americanism, “no harm, no foul”, was first used in basketball when the play in question caused no physical harm. Today, the expression is used to suggest that, if no one has been harmed by a misdeed, the “foul” should be excused. Kate Clanchy’s controversial memoir, Some Kids I Taught and What They Taught Me (2019), caused considerable psychological harm to readers – and significant reputational damage to both author and publisher. The critical discussion that ensued divided readers, with critics drawing attention to the ableist, classist, racist, and sexist undertones of the work, while Clanchy’s most vocal supporters argued that her critics were “abusive trolls” (Rajesh, 2021, para. 4) who condemned the book without reading it. Thus, this paper scrutinises the public commentary that surrounded the controversy to demonstrate that there was, indeed, “some harm, some foul”. The paper then assesses the value of harm-preventative measures available to practising Australian editors who work with problematic content in creative nonfiction texts. The paper concludes by offering an evidence-based probability of harm model for editing problematic content, with the overarching goal of minimising potential harm, and promoting safe and responsible editing practice.

Published: February 2025

The hijab controversy, a hot topic in India since January 2022, emerged from a clash between students and college authorities in Karnataka, a state in India. The dispute made its way to Karnataka’s High Court, which, on 15 March 2022, ruled that the hijab was not mandatory for religious practices. This decision stirred widespread debates, especially on social media platforms like Facebook. This study is focused on user reactions in The Times of India Daily’s official Facebook page, employing sentiment analysis to decipher public emotions, attitudes, and opinions. Nearly 200 comments posted on the verdict day were analyzed, utilizing the routine activity theory (RAT), spiral of silence theory, and online disinhibition effect. The research introduced a unique model, RAT+A, to enhance analysis. As a significant platform for public discourse, Facebook played a crucial role in capturing diverse societal sentiments and reactions regarding this social issue.

Authors: Chaudhuri Jaydip Ray
Published: February 2025

Background: Multiple sclerosis (MS) is a neurological disorder involving central nerves system. MS can affect both genders, more commonly women and younger adults. MS is associated with various risk factors and can lead to significant disability and poor quality of life.

Aim: The present study is to investigate, the clinical profile, risk factors and assess their correlation with disability using Expanded Disability Status Scale (EDSS).

Methods: This prospective observational study recruited 102 patients with MS at department of Neurology, Yashoda hospital, Hyderabad, India. All patients met the McDonald’s 2010 criteria for MS. Risk factor evaluation was done. EDSS was done for all patients. Analysis was performed after dichotomizing patients based on EDSS (≤ 3.0 and ≥ 3.5 EDSS).

Results: Out of 102 patients, women were 60 (58.2%), mean age was 47.2 ± 13.4 years. On clinical symptoms, optic neuritis was seen in 70 (68.6%), sensory involvement in 46 (45%) and bladder symptoms in 33 (32.3%). Associated peripheral nerve involvement was seen in 40 (39.2%). Hypertension was noted in 13 (12.7%), diabetic mellitus in 18 (17.6%), smoking in 38 (37.2%), alcoholism in 35 (34.3%), obesity in 28 (27.4%), 25-hydroxyvitamin D deficiency in 57 (55.8%), and non-vegetarian diet in 76 (74.6%) patients. In MS subtypes, 68 (66.6%) had RRMS, 5 (4.9%) had SPMS and 29 (28.4%) CIS. We compared the risk factors between patients with mild disability (> 3.0 EDSS) and severe disability (> 3.5 EDSS). Women (p=0.002), age>40 years (p=0.005) smoking (p=0.01), alcoholism (p=0.01), obesity (p=0.002), 25-hydroxyvitamin D deficiency (p=0.001) and vegetarian diet (p<0.0001) were significantly associated with severe disability.

Conclusion: In our study, we established female gender, age>40 years, smoking, alcoholism, obesity, 25-hydroxyvitamin D deficiency and vegetarian diet to be associated with severe disability in patients with MS.

Published: February 2025

Through the portrayal of rural left-behind children in Chinese state media, this study investigates the evolution of narratives and the societal consequences. The research seeks to uncover its media depiction of left-behind children and how these constitute cultural and policy priorities. A Systematic Literature Review (SLR) was carried out using a qualitative research approach in order to analyze 20 peer-reviewed studies. Thematic analysis highlighted major shifts in media narratives moving from early portrayals that favored the idea of material deprivation to the more recent narratives that revolved around behavioral and psychological challenges. Visual and linguistic techniques of media encourage empathy and the alignment of narratives with family responsibility and resilience often detract from the realities of systemic problems such as rural to urban inequalities. Differences between the state media and the independent media are highlighted in cross cultural comparisons, Chinese state media emphasizes social harmony and policy alignment, while independent media features systemic critiques. The study’s findings highlight the role of media in helping to form societal values and bolstering policy objectives. More balanced narratives, which integrate systemic critiques, are needed for deeper public awareness and policy reform, as well as scholarly understanding and practical strategies for media practitioners and policymakers.

Rem merupakan alat yang memiliki fungsi untuk menurunkan kecepatan atau menghentikan suatu kendaraan. Salah satu jenis rem ialah rem tromol dengan komponen utama tromol (brake drum), kampas rem (brake shoe). Besi cor FC 250 merupakan salah satu material yang digunakan brake shoe, dan pada praktiknya material tersebut kurang mampu menahan beban pengereman yang terjadi. Sehingga pada penelitian dilakukan studi penambahan kromium 1 % pada besi cor FC 250 sebagai upaya untuk meningkatkan kekuatan material tersebut. Bahan penelitian ialah FC 250 yang dicampur dengan kromium 1 %. Spesimen uji diproduksi dengan membuat cetakan pasir berbentuk Y block sesuai standar JIS G 5501. Hasil cor diproses sebagai spesimen uji komposisi, uji kekerasan, dan uji tarik. Spesimen uji tarik dibuat dengan merujuk pada standar JIS Z 2201. Target komposisi kromium pada spesimen hasil cor sekitar 1 %. Besi cor kelabu FC 250 dengan penambahan kromium 1 %, dikatakan layak digunakan sebagai material brake shoe apabila kuat tariknya minimal 357,5 N/mm2. Komposisi FC 250 + Cr 1% terdiri atas C = 3,37 %, Si = 1,84 %, Mn = 0,93 %, P = 0,19 %, S = 0,1%, dan Cr = 0,96%. Penambahan kromium 1 % pada besi cor FC 250 memberikan dampak pada kenaikan nilai kekerasan dan kuat tarik hingga 66,4% dan 38,3 %. Besi cor FC 250 + Cr 1% dapat digunakan sebagai alternatif material brake shoe rem tromol, karena nilai kuat tariknya lebih tinggi daripada tegangan maksimum yang terjadi pada brake shoe.
