This study examines the impact of constructivist physics lessons and laboratory activities on middle and high school students’ academic success. Utilizing the constructivist learning model, which emphasizes active student engagement, the research was conducted at Hyperion Theoretical High School in Chișinău, Moldova, involving 195 students across grades 6, 8, and 10. The study finds that integrating constructivist teaching methods — such as the 5E model, Flipped Classroom, and Early Physics Approach — positively influences students’ academic performance at the middle and high school level. The results indicate a significant positive correlation between students’ performance in laboratory work and their end-of-chapter evaluations. This highlights the importance of hands-on lab work in reinforcing learning and improving academic performance. The research reveals that, in middle school, girls perform better than boys in lab work and evaluations, but this difference diminishes in high school. The study suggests that constructivist lab work and assigned roles in group activities help reduce the gender gap in physics. The study indicates that physics is perceived as less masculine than traditionally thought, based on performance data and gender-related stereotypes. Despite some differences in performance, the overall constructivist environment in physics labs does not contribute to a negative experience based on gender.

Mathematics textbooks are commonly considered to be tools for efficient teaching and implementing change in mathematics classrooms worldwide, helping teachers to teach and learners to learn. When the content as described in the curriculum is not faithfully and relevantly represented in textbooks, learners’ opportunity is limited. Against this background, opportunity to learn Euclidean geometry was investigated by scrutinising four Grade 11 mathematics textbooks used in South African schools, using deductive content analysis. The Kurz Opportunity to Learn (OTL) Model was the theoretical foundation focusing on content coverage and the quality of tasks. In this paper, the embedding of context within geometry questions is investigated as one of the criteria in judging the quality of tasks. The study revealed that although the four textbooks covered almost all the Euclidean geometry topics in depth, contextualisation was absent, despite its ability to improve learners’ problem recognition, interpretation and understanding abilities. All the questions were intra-mathematical. With the use of contextualised tasks, possibly the real world can enter the mathematics classroom, so that the age-old learner question, “Why am I doing this?” may be answered with a demonstration of relevance.

The Resurgence of Trumponomics: Implications for the Future of ESG Investments in a Changing Political Landscape Innocents Alhamis
Authors: Alhamis Innocents
Published: February 2025

Public policy shapes the economic landscape, influencing everything from corporate behavior to individual investment decisions. For Environmental, Social, and Governance (ESG) investors, these policy shifts can create opportunities and challenges as they navigate an ever-changing regulatory environment. The contrast between the Trump and Biden administrations offers a striking example of how differing political agendas can affect ESG investments. Trump’s first term was marked by deregulation and policies favoring fossil fuels, which created an uncertain environment for sustainable investments. When Biden assumed office, his focus on climate action and clean energy reinvigorated the ESG sector, offering a more stable and supportive landscape for green investments. However, with Trump’s return to power in his second term, these policies are being reversed again, leading to further volatility. This paper explores how such dramatic shifts in public policy influence economic strategies and directly impact ESG investors' decisions, forcing them to constantly reassess their portfolios in response to changing political climates.

Published: February 2025

A capacidade de inovação de PMEs é um tema que ainda carece de estudos empíricos, em especial no contexto de América Latina e Caribe. Na Colômbia, empresas deste porte correspondem por 99,5% do total de negócios do país. Apesar da existência de programas de incentivo, os números mostram baixo nível de inovação e alto nível de mortalidade nos primeiros dois anos. A predominância de PMEs também não se representa nas exportações, que ainda estão concentradas em grandes players e na venda de commodities, evidenciando potencial não consolidado para produtos de alto valor agregado. A partir deste cenário, o presente estudo tem como propósito analisar os fatores de inovação em PMEs exportadoras do departamento Atlântico, parte da região do caribe colombiano que representa um dos centros com mais potencial suprimido de internacionalização. Para obtenção dos dados, foi realizada survey com as PMEs de manufatura, devido à grande concentração de negócios nesta atividade e com o propósito de reduzir vieses comparativos em empresas de setores distintos. Os resultados mostram baixo volume de recursos dedicados e incentivos para desenvolvimento de competências para a inovação dentro das organizações, nível inferior de uso de ferramentas tecnológicas em produção e processos, pouco investimento em certificações e protocolos de melhorias de processos, assim como a carência de processos sistematizados e padronizados. Evidenciou-se significativa correlação dos fatores relacionados à inovação com a capacidade percebida pelas empresas de exportar para a amostra analisada, que reforça a literatura prévia em um ambiente com baixo nível de inovação.

Bali sardinella is a fish species that contributes greatly to the Archipelago Fishing Port (PPN) Pengambengan. The potential of Bali sardinella fishery resources is abundant and of high economic value. The purpose of this study was to assess the performance of fish resource domain status with an ecosystem approach. The research was conducted for seven months from January to July 2023. Data collection was done through observation and interviews. The data analysis used was a multi-criteria analysis approach with assessment and visualization of the composite index with a flag model. Six indicators in the fish resources (SDI) domain were studied, namely standardized CPUE trends, Bali sardinella size, proportion of juveniles caught, species composition of the catch, range collapse of fish resources, and endangered, threatened, and protected species (ETP). Indicators in the fish resources domain indicate that the trend of standardized CPUE is decreasing, the trend of Bali sardinella size is relatively fixed, the proportion of juveniles caught is 53%, the species composition of the catch is a higher proportion of target fish, the range collapse of fish resources for fishing grounds is relatively fixed depending on the target species, and for ETP species caught but released. The final result of the assessment of the status of Bali sardinella fish resources based at PPN Pengambengan received a composite score of 70, so it is in a good category.
Thermal Transfer Performance of Downhole Electric Heaters for In-Situ Pyrolysis in Tar-Rich Coal

Published: February 2025

The performance of a large-size helical baffle heater in an in-situ operating is investigated using a numerical simulation method. It revealed that the fluid in the shell retains a spiral flow, and the output flow velocity is higher than in the surrounding area. However, the pitch design is rather big, resulting in a low-velocity flow zone on the backwind side. At 100 kW and 500 m³/h, the fluid flow is turbulent. 50 kW and 200 m³/h, the fluid remained laminar. As flow rate rose, the pressure of tar-rich coal formation grew dramatically. The wall temperature exhibited spiral plunger at the inlet, but the bottom temperature was symmetrically distributed. Under low power and flow, Reynolds number change has a greater impact on the combination of Nusselt and Prandtl number. The wellbore experiences higher thermal loads during downhole heating, increasing the possibility of thermal damage dramatically. An increase in the heater shell length improves the total heat transfer performance. Conventional heaters often only heat the bottom formation. Therefore, while optimizing the construction, it is vital to ensure that the weight of heater itself does not exceed the tensile strength of cable, and consider shifting down the perforation outlet or lowering the outlet.

RMSF, a tickborne infection caused by Rickettsia rickettsii, produces severe and fatal disease in humans and dogs. Since the beginning of the 21st century, cases have risen dramatically, most notably in Mexico and Brazil, where outbreaks occur in urban centers including cities with populations of > 1,000,000 persons. Reported case fatality rates can exceed 50%. Factors consistent with high case fatality include lack of awareness of disease ecology, limited capacity for diagnosis, and delay in appropriate antimicrobial treatment. The emergence of urban hyperendemic foci has been leveraged by 2 distinct but similar anthropogenic events that create disproportionately high numbers of vertebrate amplifiers of R rickettsii, as well as the tick species that transmit this pathogen in proximity with dense human populations. This often occurs in neighborhoods with a highly marginalized at-risk population that includes persons in poverty and particularly children, and health management systems that are under-resourced. We discuss strategies to reduce host dog populations, particularly in Mexico, and capybaras in Brazil. We review challenges to the control of tick populations in these settings. Robust systems are required to enhance awareness of RMSF among medical practitioners and people at risk of RMSF. Public health campaigns should incorporate innovative behavioral science (eg, diverse learning models, motivational interviews, and gamification) to increase prevention and understanding within communities. While anti-Rickettsia or anti-tick vaccines will be necessary to resolve this One Health crisis, impactful implementation will require data-driven and multiple-target innovations to address challenges with hosts, ticks, medical systems, and public welfare. The companion Currents in One Health by Foley, Backus, and López-Pérez, JAVMA, March 2025, addresses helpful information for the practicing veterinarian.

Control and resistance
Authors: Levit Irina
Published: February 2025

Using questions strategically to control witness testimony is imperative to a successful criminal trial. Witnesses are not without power and can deploy resistance strategies in the face of controlling questioning. Through an examination of question typology, question function, and answer types, this paper aims to provide a holistic understanding of how counsel and witness negotiate narrative production through the unique turn-taking system present in witness testimony. Rachel Jeantel’s testimony, in the case of Florida v. Zimmerman, was analyzed to explore the relationship between question types, question functions, and type-conforming or resisting answers. Results are in line with general counsel strategies for direct and cross-examination; counsel prefer more controlling questions, with a higher relative proportion of controlling questions in cross relative to direct examination. Type-conforming responses are the most common response in both types of examination. Resistance strategies employed by the witness are more common in cross-examination. However, there exist interesting dynamics between avoidance, correction, and confirmation-eliciting questions. Finally, the presence of question clusters and interruptions may contribute to narrative control and resistance to such control.

Effects of Depressive Disorder on Employment Income in Brazil
Authors: Benedicto Bianca Vieira , Soares Laís de Sousa Abreu , Teixeira Evandro Camargos
Published: February 2025

Introduction
Depressive disorder is prevalent worldwide, with a particularly high impact in Brazil, where it mainly affects women. While most research on depression focuses on its clinical aspects, there is a scarcity of studies exploring the economic consequences of the disorder.
Objective
This study aims to analyze the effect of depressive disorder on income from work in Brazil in 2008, considering both men and women and how the illness affects them differently.
Methodology
Two dummy endogenous variable models were estimated to assess the impact of depressive disorder on labor income. These models account for the distinct effects of the disorder on men and women, reflecting the varying characteristics of the illness's impacte.
Results
The findings indicate that depressive disorder reduces labor income by approximately 32.6% for women and 29.8% for men. This decrease in revenue is attributed to a reduction in individual productivity. Additionally, the illness can reduce labor supply, with some individuals leaving the labor market entirely.
Conclusions
The results highlight the significant economic impact of depressive disorder on labor income in Brazil. The findings suggest the need to incorporate mental health care into primary care public policies to mitigate the financial consequences of the illness

Los porcentajes de hogares con pobreza inducida por vivienda son similares a los estimados utilizando el umbral del 30%, pero presentan una distribución considerablemente diferente según la composición sociodemográfica del hogar. Los hogares inquilinos con mayor dependencia económica, principalmente aquellos con niños/as, y/o encabezados por jefes/ as jóvenes, bajo nivel educativo y empleos poco calificados, tienen mayores probabilidades de enfrentar problemas de asequibilidad.
Conclusiones
Un enfoque residual permite un análisis más preciso de las restricciones que enfrentan los hogares inquilinos, al evidenciar la pobreza resultante de la sobrecarga de los gastos en vivienda, especialmente debido a los altos costos de los alquileres.

Published: February 2025

AbstractMicrolearning is becoming more popular in education due to its convenience, flexibility,  and effectiveness.  The popularity emerges from the use of chunking of materials in short and understandable components  that makes it easier for learners to attain the information at their convenience. Preferably, learning materials are microlearning-designed. However, since not many teachers are well-informed about microlearning, the existing learning materials may not be microlearning-based designed. Studies focusing on this issue are relatively limited. This study aims to analyze whether English learning materials at senior high school are designed based on microlearning principles. Twenty four English learning materials covering various types of materials including textbook, e-module, webpage, as well as, pre-recorded teaching and YouTube videos designed for grade X, XI, and XII collected from three senior high schools in Jakarta were analyzed using microlearning framework. The findings of this study show that the existing learning materials do not conform to microlearning  principles. The results of this study reveals the needs to design microlearning-based materials, break the lesson units into micro contents, and produce microlearning object materials for English lessons in high schools. Key Words: microlearning, English learning materials, microlearning object materials

Kopi merupakan komoditas perkebunan unggulan di Kabupaten Garut. Penelitian ini bertujuan untuk menganalisis kelayakan usaha dari aspek non-finansial dan finansial, serta mengkaji tingkat kepekaan dan analisis nilai pengganti terhadap fluktuasi harga bahan baku. Metode yang digunakan adalah kuantitatif deskriptif, dengan fokus pada analisis kelayakan usaha dari aspek non-finansial dan finansial. Aspek non-finansial meliputi pasar, teknis, manajemen dan hukum, sosial, ekonomi dan budaya, serta lingkungan. Aspek finansial dianalisis menggunakan arus kas dan kriteria investasi seperti NPV, Gross B/C, Net B/C, IRR, dan PP. Selain itu, analisis sensitivitas dan analisis nilai pengganti juga digunakan.  Hasil analisis kelayakan usaha dari aspek non-finansial menunjukkan bahwa usaha ini layak meskipun terdapat kekurangan pada aspek teknis, yang dapat diimbangi oleh aspek pasar dan lingkungan. Dari segi finansial, usaha pengolahan Kopi Arabika Talaga Hurip juga dinyatakan layak, dengan inflow sebesar Rp 52.800.000 hasil dari penjualan 240 kg kopi dengan harga Rp 220.000/kg. Outflow meliputi biaya investasi sebesar Rp 69.942.000 dengan penyusutan Rp 7.565.725/tahun, biaya tetap sebesar Rp 11.107.000/tahun, dan biaya variabel Rp 25.050.400/tahun. Kriteria kelayakan investasi dalam penelitian ini menunjukkan NPV sebesar Rp 24.042.745, Gross B/C 1,09, Net B/C 1,55, IRR 24,65 persen, dan PP 6,1 tahun, yang berarti usaha Talaga Hurip Kopi memenuhi semua kriteria kelayakan investasi.
