What scale for local food system planning? Insights from French case studies
Authors: Liu Tianzhu
Published: January 2025

This paper explores the critical role of scale in food system planning. Although there is growing aware­ness of the importance of considering the city-region scale in food system planning, a comprehen­sive understanding of the scale of planning is lacking in this evolving policy field. This study addresses this gap by analyzing a series of food sys­tem planning projects developed at different scales in France. Drawing on document analysis and semi-structured interviews with officials, the paper ex­plores three key dimensions of scale: administra­tive, action, and governance scales. Findings reveal that there is no relevant one-size-fits-all administra­tive scale for all food system planning projects. Instead, each administrative scale has its own strengths and limitations. Smaller-scale planning is often more efficient for rapid implementation but may fall into the local trap, whereas larger-scale planning offers a more appropriate scale to meet the food supply-demand balance at a city-region scale but risks a long process of coordination and inefficient implementation. The study identifies local political willingness, legal competences, and spatial appropriateness as significant factors when determining at which scale to develop food system planning. Moreover, the study investigates how localities define “local” within their food system planning practices. They vary from the ambiguous “as close as possible,” administrative units, to quantified distances, but most action scales extend administrative boundaries. Finally, the study identi­fies locally designed governance strategies to match action scales and administrative scales, with empiri­cal evidence from food system planning experi­ments applying cross-scalar and cross-local govern­ance models. It also highlights challenges such as unclear distribution of responsibilities among juris­dictions, which hinders local implementation of actions. By providing empirical evidence, the paper contributes to a nuanced understanding of the scale issue in food system planning and emphasizes the importance of governance strategies and insti­tutional design. The paper offers practitioners guid­ance on identifying and determining the scale of planning and governance strategies, while also pro­viding scholars with directions for future research.

The Role of Ontology in Developing Language Skills
Authors: Sari Nur Nilam , Sari Dewi Permata , Taufiqurrahman Taufiqurrahman , Arifin Bahri
Published: January 2025

Language learning transcends mere vocabulary acquisition and grammatical understanding, encompassing the intricate interplay between language, thought, and existence. This research investigates how ontological perspectives-realism, idealism, and constructivism-shape language education practices and influence learners' cognitive and linguistic development. Employing a literature review methodology, the study synthesizes contemporary research to elucidate the relationship between ontological beliefs and effective language skill development. Realism, with its emphasis on objective knowledge and standardized assessment, promotes structured language instruction but may stifle creativity and contextual relevance. In contrast, idealism encourages learners to engage with language as a vehicle for expressing personal and cultural identities, fostering critical thinking and collaborative learning. Constructivism emphasizes active engagement and social interaction, positioning language acquisition as a dynamic process rooted in real-world contexts. The findings underscore the need for educators to reflect on their ontological assumptions, balancing structured approaches with those that prioritize meaning and interaction. By integrating diverse ontological perspectives, language education can cultivate proficiency and facilitate meaningful communication, preparing learners for real-world linguistic challenges. This research offers valuable insights for educators, informing curriculum design and teaching strategies to enhance language learning experiences.

Authors: Mira Andrea , Smith Constanza
Published: January 2025

Las funciones ejecutivas son fundamentales para el desarrollo de las habilidades de autorregulación y para el desarrollo socioemocional en los niños. Es por esto que se hace necesario poder conocer que factores van influyendo en este proceso. Uno de estos factores a considerar son las interacciones entre los niños y sus padres. Es por esto que el objetivo de este trabajo es poder describir el rol que tendrían los padres en el desarrollo de las funciones ejecutivas de sus hijos. Se realizó una revisión teórica en torno a lo que se denomina andamiaje (scaffolding), para así poder reflexionar acerca de cómo los padres podrían ir facilitando el desarrollo de las funciones ejecutivas (FE) de sus hijos e hijas a través de las interacciones con ellos. En los estudios revisados se evidenció una importante relación entre el andamiaje y el desarrollo de las FE en los niños, esto probablemente por rol que tiene el contexto social en el desarrollo de los niños. Es así como se podría integrar en las intervenciones de terapia ocupacional el fortalecimiento de rol de los padres en el desarrollo de las FE a través del andamiaje.

Necropolítica y entrevistas criminales en Brasil: Un análisis del legado de la tortura y los principios Méndez
Authors: Dos Santos de Almeida Mariana
Published: January 2025

This study investigates the persistence of torture and police brutality in Brazil, focusing on the contradictions between legal principles and actual practices within the criminal justice system. The objective is to identify the main constitutional principles and rights garanteed and examine how, besides them, historical legacies, institutional culture, and contemporary policies contribute to the ongoing violations of human rights, particularly during criminal interviews. The research employs a qualitative methodology, including a review of historical and legal documents, case studies, and analyses of recent reports and precedents. It explores the evolution of torture practices from Brazil’s colonial past through its latest military dictatorship and into the present, highlighting systemic issues in the legal and judicial frameworks. Key findings reveal a troubling continuity of torture mechanisms and police brutality, sustained by institutional complicity and socio-political factors. Despite formal constitutional protections, systemic violence remains pervasive, disproportionately affecting marginalized communities. The study identifies significant gaps between constitutional guarantees and actual practices, particularly in the application of Precedent 70 from Rio de Janeiro State’s Court and the handling of custody hearings in Brazil, among many others. It also emphasizes the role of societal acceptance and institutional biases in perpetuating these abuses. The conclusions underscore the need for comprehensive reforms to bridge the gap between legal norms and practical realities. Enhancing accountability mechanisms, revising problematic legal precedents, and implementing the Méndez Principles for humane interviewing practices are essential steps. The study highlights the importance of addressing underlying socio-economic inequalities and fostering a cultural shift towards genuine respect for human rights to effectively combat torture and brutality. The significance of this research lies in its potential to inform some policy changes and legal reforms to enhance the Brazilian justice system, without attempting to cover all possibilities. By providing a detailed analysis of the systemic issues and proposing actionable solutions, the study contributes to the broader discourse on human rights and justice, advocating for a transformative approach to addressing entrenched abuses, ensuring the protection of constitutional rights and fortifying the democratic rule of law.

STABILNOŚĆ I NIESTABILNOŚĆ UKŁADÓW (ELEKTRO)CHEMICZNYCH
Authors: Orlik Marek
Published: January 2025

The article is an introduction to the dynamic self-organization of chemical systems, with particular emphasis on the electrode processes. Experimental manifestations of this type of phenomena include multistability (mainly bistability), spontaneous oscillations of the system’s state, and formation of spatiotemporal patterns. In general, such phenomena occur when a single steady state loses stability in favor of other, more complex dynamic behaviors, which are possible in systems with non-linear characteristics containing steps of positive and negative feedback loops in their kinetic mechanisms. From a mathematical point of view, the transition to multistability or oscillations means appropriate bifurcations in the solutions of differential equations describing the dynamics of the system. With regard to electrochemical systems, the key role of negative differential resistance (N or S type) in the current-potential characteristics of the electrode processes has been indicated as the typical cause of feedback loop. In the presence of appropriate series resistance in the electrical circuit, combined with the relatively slow diffusion of reactants into the electrode, this can lead to oscillations, as well as to multistability. A linear stability analysis of a one- and two-dimensional electrochemical system is outlined, with the diagnosis of the saddle-node bifurcation (the route to multistability) and the Hopf bifurcation (the typical route to oscillation). For illustrative purposes, selected manifestations of dynamic self-organization are summarized: oscillations and bistability in the electroreduction of nickel(II) thiocyanate complexes, tristability in the electroreduction of azide nickel(II) complexes, convectively generated bistability in the electroreduction of Hg(II) and the formation of luminescent convective structures in thin-film electrolysis of rubrene.

KRYSZTAŁY ‒ OD MINERALOGII DO RENTGENOWSKIEJ ANALIZY STRUKTURALNEJ
Authors: Kozioł Anna
Published: January 2025

This work is an attempt to present the history of structural research at the new university, which was established after the war in 1944. The university was created from scratch ‒ based on random buildings, by people with different experience and mostly displaced from their hometowns. At the Faculty of Natural Sciences of the Maria Curie-Skłodowska University in the years 1945‒1951, crystallography was part of geological and mineralogical research. Students of the Faculty of Natural Sciences and Pharmacy had a "crystallography" section among the subjects they studied. After the reorganization of the university structure, the Department and next the Laboratory of Crystallography became part of the Faculty of Mathematics, Physics and Chemistry. Crystallography was taught only to chemistry students, and the subject of research was phase transformations of two-component systems. It was the crystal chemistry of solid phases, studied mainly by thermal and microscopic methods. Equipping the laboratory with an X-ray generator and cameras-goniometers for photographic registration of diffraction patterns, and later for counter collection on a powder diffractometer, enabled the use of the applied X-ray crystallography. Phase transformations of zeolites, polymer structures (degree of crystallinity) and porous materials were investigated. The use of the SAXS method made it possible to extend the research to nano- and microcrystalline phases. And above all, equipping the laboratory with single-crystal X-ray diffractometers makes it possible to study what is basic and most important in chemistry, i.e. the structure of newly synthesized compounds. Analysis of the stereochemistry of molecules, including the determination of absolute configurations, allows the correlation of physicochemical, spectroscopic and biological properties with the structure of compounds. Such research is currently carried out by crystallographers from the Faculty of Chemistry of UMCS in cooperation with, among others, medical universities

Published: January 2025

Anemia is one of the health problems that still affects Indonesia. One of the causes of anemia is a lack of knowledge and iron supplement adherence, which can lead to anemia. This research aims to determine the effect of group discussion method education on iron supplement adherence and Hemoglobin levels in female students at SMAN 1 Senduro, Lumajang. This research was a quasi-experimental pretest-posttest quantitative with a non-probability total sampling technique. The sample used in this research was adolescent girls, with 41 students. Measurement of the level of adherence used the Morisky Medication Adherence Scale (MMAS-8) and given the intervention of pretest and post-test. Data was tested using the Wilcoxon Signed Rank Test. The results of this research showed that adolescents with iron supplement adherence before group discussions were in the low category 41 (100%). After the group discussion, the high category was 2 (4.9%), low 21 (51.2%); before the group discussion, the average Hb level was 10.65mg/dl; after the group discussion, the average Hb result was 11.37 mg/dl. The results of the Wilcoxon test obtained a p-value of 0.000 (p < 0.05), which means that there is a significant effect of the provision of education on group discussion methods in adolescent girls. An increase influenced the increase in hemoglobin levels in the consumption of blood supplement tablets in adolescent girls, showing active participation and changes from before and after the group discussion. Respondents who remained anemic after the group discussion were due to a lack of iron needs and a lack of knowledge of consuming nutritious food.

Published: January 2025

The increasing trend of industrial development has led to rapid changes in land use over the past few years. The changes in land use in Saraburi Province were studied during three periods: the years 2000, 2010, and 2021, using Landsat satellite imagery processed with the Google Earth Engine (GEE) platform. The Random Forest (RF) machine learning algorithm was employed to classify land use activities into five categories based on the criteria set by the Department of Land Development. The overall accuracy values for land use were 83.59%, 82.42%, and 80.78%, respectively. The changes in land use have clearly affected the urban and built-up area. In 2000, there were only 7,561.15 ha, but by 2021, the area had increased to 34,221.11 ha. Forest areas also saw an increase. In 2000, there were only 79,626.26 ha, which increased to 163,542.05 ha in 2021, reflecting that Saraburi Province places importance on green areas. In contrast, agricultural areas decreased, which was attributed to the increasing number of households, according to the statistical report from the Department of Provincial Administration. In 2000, there were 168,979 households, and by 2021, they had increased to 288,275 households, resulting in a change in land use from agricultural areas to urban and built-up areas, totaling 22,114.95 ha. This information can be used as a guideline for planning development and land use to promote Saraburi Province, aiming towards becoming an eco-industrial city that is livable and has sustainable environmental quality in the future.

The study involves seventeen athletes, divided into volleyball and track and field groups, undergoing a series of repeated maximal sprints with minimal recovery. The activity involves seven repeated sprints across a 20m straight line. The variables captured for the study were anthropological (height, weight and sitting height), physiological (RHR, PHRavg, blood sugar (pre and post), fatigue index (10m and 20m)) and skill performance variables (average time, total time, maximum time and speed (10m and 20m)). The procedure for data analysis involved frequency, mean, standard deviation, zscore, independent and dependent t-test. The independent t-test result revealed that there were significant differences in the skill performance variables (Average time (20m), p = 0.03; Total time (20m), p = 0.03; Maximum time (20m), p = 0.01; Speed (20m), p = 0.00) between the volleyball and athletics athletes. The dependent t-test showed that there were significant differences between the physiological (Fatigue index (10m vs 20m), p = 0.01; Average time (10m vs 20m), p = 0.00; Total time (10m vs 20m), p = 0.00; Maximum time (10m vs 20m), p = 0.00; Speed (10m vs 20m), p = 0.00) and skill performance variables considered for the study. The study provides valuable insights into the distinct RSA profiles of university athletes, offering practical implications for enhancing training programs and athletic performance through sport-specific monitoring and targeted interventions.

It is no secret that the costs of getting a college education are steadily increasing. At the Southern Oregon University (SOU) Hannon Library, we are seeing the way our students struggle increasingly to afford tuition in addition to rent, food, and other necessities, and the high cost of textbooks and other course materials is only exacerbating this problem for certain student demographics. Although a large portion of our students come from the immediate region, we have students attending from throughout Oregon, and many more that come from California and other western states. We serve many first-generation students as well as nontraditional students. It is common for our students to work multiple jobs to be able to afford their education, and many report that they are unable to meet college expenses with their expected resources. Understanding the ways that textbook affordability has become a real barrier to success for so many SOU students, we wanted to do our part to reduce the cost of course materials for students by focusing on providing access to currently required texts in print or digital forms and by promoting the use of open educational resources across campus.

O câncer de bexiga é uma das neoplasias mais prevalentes no trato urinário, caracterizado por alta morbidade e disparidades nos desfechos clínicos devido a desigualdades regionais e demográficas. Este estudo objetivou analisar os padrões de internação hospitalar por câncer de bexiga no Brasil entre 2014 e 2023, considerando aspectos temporais, regionais e sociodemográficos. Trata-se de uma análise descritiva baseada em dados secundários do Sistema de Informações Hospitalares do SUS (SIH/SUS), complementada por revisão de literatura relevante. Os resultados evidenciaram uma predominância de internações em homens acima de 60 anos, com destaque para as regiões Sudeste e Sul, que apresentaram maior número de casos e menores taxas de mortalidade. Em contrapartida, as regiões Norte e Nordeste, com menor infraestrutura de saúde, registraram taxas de mortalidade mais elevadas. O número total de internações aumentou 74,8% no período analisado, mas as taxas de mortalidade geral mostraram leve redução. A ausência de informações sobre subtipos histológicos e dados limitados sobre raça/cor nos registros hospitalares destacam desafios adicionais para a análise. Este estudo reforça a necessidade de políticas públicas para reduzir desigualdades regionais e ampliar o acesso a diagnósticos precoces e tratamentos eficazes. A inclusão de informações mais detalhadas em bases de dados hospitalares é essencial para análises mais robustas e o desenvolvimento de estratégias preventivas e terapêuticas direcionadas.

Os transtornos do sono representam um desafio significativo para a saúde pública, demandando intervenções farmacológicas eficazes e seguras. Este estudo realizou uma revisão integrativa sobre o uso da trazodona na terapia de indução e no tratamento de transtornos do sono, comparando sua eficácia e segurança às Z-drugs e benzodiazepínicos. A trazodona demonstrou eficácia na melhora da latência do sono, aumento do sono profundo e aprimoramento da qualidade subjetiva, com um perfil de segurança superior devido ao menor risco de dependência e insônia rebote. Em contrapartida, as Z-drugs e benzodiazepínicos, embora eficazes, apresentam limitações como potencial de dependência, efeitos adversos neurocognitivos e alterações na arquitetura do sono. Esses achados reforçam a relevância da trazodona como uma alternativa terapêutica promissora, especialmente para pacientes com contraindicações ou intolerâncias aos hipnóticos tradicionais.

A realização de visitas técnicas no ensino de biologia é uma estratégia educacional que envolve a realização de visitas a locais relevantes à aprendizagem. Durante essas visitas, os estudantes têm a oportunidade de observar conceitos biológicos na prática, interagir com profissionais da área e explorar ambientes que complementam o ensino teórico. O trabalho em questão foi realizado no ano letivo de 2022, envolvendo tanto bolsistas do Programa Institucional de Bolsas de Iniciação à Docência (PIBID) como estudantes do Instituto Federal de Educação, Ciência e Tecnologia da Bahia (IFBA) - Campus Ilhéus, onde foi desenvolvido um projeto de realização de visita técnica. Este projeto envolveu turmas do quarto ano dos cursos de Edificações e Informática. Os alunos foram direcionados a visitar a coleção de animais e o serpentário da Universidade Estadual de Santa Cruz (UESC). Essa iniciativa ocorreu em paralelo às aulas teóricas, onde os estudantes estavam estudando Ecologia. Durante as visitas, eles tiveram a oportunidade de compreender, na prática, a importância da fauna para o funcionamento dos ecossistemas e suas interações com o ambiente natural. Os alunos tiveram a chance de explorar a coleção de mamíferos, que é supervisionada pelo professor Dr. Martín Alvarez. Lá, puderam observar animais taxidermizados e exemplares preservados em álcool, como morcegos. Também visitaram o laboratório de Entomologia, orientado pelo professor Dr. Aníbal Ramadan, onde tiveram contato com caixas entomológicas e examinaram ácaros sob microscópio. Além disso, eles visitaram o serpentário, que é coordenado pelo professor Dr. Antônio Argolo. Nesse local, tiveram a oportunidade de observar várias cobras preservadas em álcool e aprenderam sobre animais peçonhentos e não peçonhentos. Durante as visitas, receberam informações valiosas sobre a importância desses animais e as medidas de conservação necessárias. Dessa forma, o projeto pode proporcionar uma compreensão mais profunda da biologia, estimulando a curiosidade, promovendo a aplicação de conhecimentos e preparando os alunos para futuras carreiras na área científica. Além disso, as visitas técnicas ajudaram a contextualizar os conceitos biológicos no mundo real, tornando o aprendizado mais significativo e memorável.
