Authors:   , Costa Antonio Cleyton Arruda de Azevedo
Published: February 2025

O processamento dos produtos cárneos na indústria visa aumentar a vida útil do produto, bem como o aproveitamento integral das partes dos animais e dentre esses produtos cárneos, o hambúrguer deixa de ser coadjuvante e passar a ser um alimento principal devido a sua praticidade e características nutricionais, contudo devido à alta manipulação do alimento, ele fica sujeito à contaminação microbiológica por agentes deteriorantes e patogênicos, podendo acarretar doenças veiculadas por alimento, como as intoxicações estafilocócicas, além disso, alguns microrganismos patogênicos apresentam genes de resistência antimicrobiana o que gerar um problema de saúde pública relacionado à antibioticoterapia dos pacientes acometidos por doenças veiculadas por alimentos. Diante dessa problemática, o presente trabalho objetivou avaliar a qualidade microbiológica dos hambúrgueres artesanais comercializados em Mossoró, RN e verificar o perfil molecular de produção de toxinas e de resistência antimicrobiana estafilocócica de nove estabelecimentos especializados em hambúrguer artesanal. Para alcançar os objetivos foi realizada a contagem de microrganismos mesófilos e estafilococos de hambúrguer artesanal mal passado comercializado em Mossoró, RN, bem como realizada a busca por genes de produção de enterotoxinas e o perfil de resistência antimicrobiana dos Staphylococcus aureus isolados dos hambúrgueres. Após a realização das análises, constatou-se que todas as amostras apresentaram uma contaminação elevada de microrganismos mesófilos (5,2 a 6,7 log UFC/g). Já as contagens de estafilococos revelou que três estabelecimentos estavam fora dos padrões da legislação (3,7; 5,4; 4,3 log UFC/g), entretanto houve crescimento de estafilococos coagulase positiva em amostras de quatro estabelecimentos (1, 4, 5 e 7), dos quatro, três estabelecimentos (4, 5, 7), apresentaram um padrão genético para produção de enterotoxinas A e C e de resistência antimicrobiana MecA e MecC, sendo que o estabelecimento cinco apresentou dupla expressão de enterotoxinas e de gene de resistência antimicrobiana, já o antibiograma revelou que dos nove antibióticos testados, cinco já não apresentava mais ação contra os Staphylococcus aureus isolados os quatro estabelecimentos. Com isso pode-se inferir que, apesar da Legislação permitir um número máximo de microrganismos no alimento, os mesmos podem produzir toxinas e resistir à vários antibióticos de uso clínico, dificultando o tratamento do paciente, bem como que a manipulação e/ou armazenamento do alimento está sendo realizado de forma inadequada, sendo necessário uma rigidez maior nas boas práticas de manipulação, bem como na legislação.
Projeto e desenvolvimento de uma plataforma automatizável para sensor baseado na ressonância de plasmons de superfície
Authors:   , Silva Francisco Josiran da
Published: February 2025

Sistemas de detecção de eventos biológicos são essenciais para o entendimento e monitoramento
de interações moleculares. Dentre as tecnologias de detecção, comumente usadas, as baseadas em
ressonância de Plasmons de Superfície (SPR) ganham destaque devido a sua alta sensibilidade. A
instrumentação de sensores SPR exige componentes ópticos, eletrônicos, fluídicos e mecânicos,
cuidadosamente posicionados para a correta excitação do fenômeno. Normalmente, estes
componentes são rearranjados em posições fixas. Eventuais ajustes são realizados de maneira
manual, de modo a ajustar o sensor para que funcionem sempre em uma mesma condição
de uso. Além disso, muitos sensores contam com instrumentação volumosa e procedimentos
caros, exigindo operadores bem treinados e infraestrutura avançada de laboratório para ajustes
dos componentes. O biochip PPBIO possibilita o desenvolvimento de sensores SPR de forma
prática, menos complexa, evita-se a necessidade de elementos mecânicos rotacionais. Todavia,
as estruturas para esse biochip também são baseadas em componentes com posições fixas. Este
trabalho busca realizar análises mais rápidas em relação a plataforma mecânica, otimizando
o processamento e a aquisição de dados. Os resultados obtidos, por meio da análise entre a
curva teórica e experimental, permitiram concluir que quanto mais acentuada e profunda a curva
SPR melhor acoplamento óptico e, consequentemente, melhor o fenômeno SPR. Possibilitaram
analisar a largura da curva SPR, concluindo-se que quanto mais acentuada, maior a precisão
de detecção e melhor acoplamento óptico; e quanto menor a largura, melhor a sensibilidade,
consequentemente, melhor o fenômeno SPR. Dessa forma, a plataforma automatizada, como
contribuição científica, tem aplicação para operar no modo de interrogação angular, pois fornece
um melhor alinhamento do acoplamento óptico. Tendo como uma das vantagens da plataforma,
a não necessidade do uso sistemas rotacionais, a redução do efeitos térmicos capaz de evitar
leves distorções no caminho óptico, gerando uma melhor resposta, estabilidade, sensibilidade
com boa repetitividade e maior precisão da curva SPR
A study on educational attainment and career development of second generation immigrants
Authors: Takahashi Tomoko
Published: February 2025

There are second-generation immigrants across the globe. These people were born in the country one or both parents migrated to. They can face challenges different to those experienced by people whose families are native to a given country. Researchers are working towards the goal of
a fairer society and, as such, many are focusing on the plight of immigrants and second generation immigrants. Tomoko Takahashi, Global Education Center, Kindai University, Japan, is a researcher whose current project focuses on the issues facing second generation immigrants when it comes
to attaining education and career development. Through her research contributions she hopes to help improve the education of children with foreign roots currently attending Japanese schools. Takahashi worked as an elementary school teacher for several years and started her current project
to address the situation in Japan where the Government is not accepting immigrants and doesn’t recognise foreigners residing in Japan as immigrants. She believes there is a lack of awareness, measures and support in educational settings, the workplace and society. By exploring the educational
attainment and career development of the second generation, she believes it is possible to clarify the issues facing Japanese society and provide solutions. The project focuses on the children of first-generation Chinese immigrants as they encounter significant challenges relating to education
in Japan. As many first-generation Chinese immigrants only speak Chinese, they are unable to help their children with their Japanese homework, give educational advice or effectively communicate with teachers.
Understanding school refusal behavior using SRAS‐R and its application to behavioral consultation techniques
Authors: Yano Yoshinori
Published: February 2025

Unauthorised student absences from school occur around the world. Given the importance of school, it's crucial to understand why this occurs and how the situation might be improved. Existing measures include psycho-educational, psycho-analytic and behavioral approaches but the issue
is growing and more needs to be done to better understand non-attendance. If understanding can be improved, more effective measures can be put in place to encourage children to attend their classes. Associate Professor Yoshinori Yano leads a team based within the Department of Early Childhood
Education at Sakushin Gakuin University Women’s College in Japan applying a variety of techniques and approaches to better understanding school refusal behavior. Yano is particularly interested in special needs education and applied behavior analysis. He is applying the
concept of applied behavior analysis to his work to understand the actions of people and visualise achievement status. He is looking at truant behavior from the perspectives of special support education and student guidance. Yano is using the School Refusal Assessment Scale (SRAS-R) to understand
school absences. There are two types of the scale: one for professional grading and one for parental grading. The four functions of the SRAS-R are: avoidance of unpleasant stimuli related to school; avoidance of evaluation and social situations (ESE); attention-seeking behavior of others;
and having fun outside of school. Studies have been conducted using the Japanese version of SRAS‐R, the SRAS‐R‐J, but none in clinical settings outside of school.
Practical research on constructing a framework for interdisciplinary lessons through collaboration between teachers
Authors: Nihashi Takuya
Published: February 2025

Cross-curricular education is gaining traction in Japan and beyond as it supports the development of a well-rounded education. It involves integrating multiple subjects in a way that encourages
students to forge links between different disciplines. Teacher training, however, doesn't tend to include how to incorporate cross-curricular classes or the communication process needed for the
development of these types of classes. Dr Takuya Nihashi, Faculty of Liberal Arts at Osaka Shoin Women’s University, is conducting interconnected research studies with the goal of addressing
this. He wants to improve teacher training so that teachers are able to develop cross-curricular classes. Communication between teachers with different specialities is a key part of creating
cross-curricular learning. Therefore, Nihashi explored the process of planning interdisciplinary lessons through collaboration between teachers. He interviewed teachers interested in cross-curricular
classes and with awareness of the challenges to understand how teachers create their lesson plans, with emphasis on the discussions that occur between teachers. Nihashi analysed these interviews using
the Modified Grounded Theory Approach (M-GTA), which identified four key themes in the planning process: 'this person can do it', which rates to how teachers decide who to collaborate with; 'this can
work as a lesson', which concerns how teachers explore the connections between subjects; 'belief in a good lesson', which relates to teachers' motivation to create a good lesson; and 'lesson planning
discussions', relating to the practical conversations involved in bringing lesson plans to life.

Authors: Thakur Madhur , Maurer Eric W , Tran Kim Ngan , Tholkes Anthony , Rajamani Sripriya , Dwivedi Roli
Published: February 2025

UNSTRUCTURED

Federally Qualified Health Centers (FQHCs) provide service to medically underserved areas and communities, providing care to over 32 million patients annually. The burden of diabetes is increasing, but often, the vulnerable communities served by FQHCs lag in the management of the disease due to limited resources and related social determinants of health. With the increasing adoption of technologies in health care delivery, digital tools for continuous glucose monitoring (CGM) are being used to improve disease management and increase patient engagement. In this viewpoint, we share insights on the implementation of a CGM program at an FQHC, the Community-University Health Care Center (CUHCC) in Minneapolis, Minnesota. Our intent is to improve diabetes management through better monitoring of glucose and to ensure that the CGM program enables our organization’s overarching digital strategy. Given the resource limitations of our population, we provided Libre Pro devices to uninsured patients through grants to improve health care equity. We used an interdisciplinary approach involving pharmacists, nurses, and clinicians and used hemoglobin A1c (HbA1c) levels as a measure of diabetes management. We assessed the CGM program and noted key aspects to guide future implementation and scalability. We recruited 148 participants with a mean age of 54 years; 39.8% (59/148) self-identified their race as non-White, 9.5% (14/148) self-identified their ethnicity as Hispanic or Latino, and one-third (53/148, 35.8%) were uninsured. Participants had diverse language preferences, with Spanish (54/148, 36.5%), English (52/148, 35.1%), Somali (21/148, 14.2%), and other languages (21/148, 14.2%). Their clinical characteristics included an average BMI of 29.91 kg/m2 and a mean baseline HbA1c level of 9.73%. Results indicate that the CGM program reduced HbA1c levels significantly from baseline to first follow-up (P<.001) and second follow-up (P<.001), but no significant difference between the first and second follow-up (P=.94). We share key lessons learned on cultural and language barriers, the digital divide, technical issues, and interoperability needs. These key lessons are generalizable for improving implementation at FQHCs and refining digital strategies for future scalability.

¿Qué hay de nuevo en la cultura? Aportes desde la Encuesta Nacional de Consumos Culturales de Argentina
Authors: Moguillansky Marina , Focás Brenda
Published: February 2025

Este artículo presenta algunos hallazgos de la Encuesta Nacional de Consumos Culturales (ENCC) realizada en 2022 en Argentina. Se reconstruyen los antecedentes de estudios de consumos culturales en América Latina para describir luego el diseño metodológico y las dimensiones que aborda la encuesta, así como los desafíos de realizar esta medición apenas concluida la pandemia de COVID-19. Se hace foco en los resultados sobre consumo de televisión y plataformas de streaming, uso de redes sociales y lectura de noticias. Los datos de la ENCC muestran que la televisión sigue siendo relevante, aunque el streaming y las redes han expandido sus audiencias. El noticiero sigue teniendo un rol importante en los consumos de información, pero se evidencia un creciente uso de las redes sociales para informarse. Se observa como novedad la simultaneidad e integración de diferentes tipos de prácticas, por ejemplo, el uso de redes sociales para comentar lo que se está viendo en televisión o en plataformas. Se concluye resaltando la importancia de los datos de la ENCC para la investigación y formulación de políticas públicas orientadas a mejorar el acceso y la participación ciudadana.

INTRODUCTION: Soft tissue tumors are a diverse group of growths that can occur anywhere in the body. While sarcoma only account for about 1% of all malignant neoplasms, they come in many different types and often recur after treatment. This makes accurate diagnosis and monitoring of these tumors and postoperative scars essential.

OBJECTIVE: To analyze scientific works of the latest 5 years, which examined medical imaging techniques, specifically multiparametric ultrasound and MRI, and assess their effectiveness in diagnosing soft tissue tumors, including sarcomas and their recurrences.

MATERIALS AND METHODS: Search queries were performed in the Google Scholar, PubMed and Web of Science databases and were based on the keywords: «sarcoma of soft tissue», «soft tissue tumor», «soft tissue Ultrasound», «soft tissue MRI», «soft tissue CEUS».

RESULTS: The literature analysis determined that multiparametric contrast-enhanced ultrasound is more effective in diagnosing soft tissue tumors than studies without contrast and can be comparable in accuracy to magnetic resonance imaging. However, the accuracy rates reported in publications on this topic were significantly influenced by factors such as the criteria used to select patients, the design of the studies, and the size of the samples.

DISCUSSION: This review shows that developing an optimal diagnostic algorithm for soft tissue tumor requires a comprehensive approach considering both the strengths and weaknesses of individual methods and the potential of cost-effective new technologies to improve diagnostic quality.

CONCLUSION: Additional research needs to investigate all modes of multiparametric ultrasound and magnetic resonance imaging, as well as the role of echo contrast both in a diagnostic algorithm for detecting soft tissue tumors and in monitoring after surgical resection for sarcomas.

A Dádiva em todo lugar: notas a propósito do centenário da obra-prima de Marcel Mauss
Authors: Esteves Leonardo Leal
Published: February 2025

Neste texto, procuro discutir a respeito da importância do Ensaio sobre a Dádiva, após quase um século de sua publicação original. De modo particular, busco chamar atenção para alguns debates mais significativos em torno da obra, bem como refletir acerca de desdobramentos desse clássico da Antropologia. Sem a pretensão de ser exaustivo e consciente de que há, possivelmente, análises muito mais profícuas sobre as contribuições teóricas do seu autor, esse texto é um convite à reflexão acerca da atualidade da obra-prima de Marcel Mauss. A partir da releitura do Ensaio e da análise de comentaristas e de trabalhos em diferentes áreas na antropologia procuro chamar atenção para a importância da obra maussiana para a compreensão teórica de aspectos no Direito, relações de parentesco, formas de organização política, questões relativas à economia, religião, o tema das festas e da cultura popular, entre outros aspectos. Uma obra, em outras palavras, cujas fronteiras e influências interdisciplinares não deixam de se expandir, ao mesmo tempo em que continua sendo referência central para compreensão de diferentes aspectos sob a perspectiva da Antropologia e para nos orientar como coletividade nesses tempos desnorteantes em que vivemos. Em outros termos, mesmo depois de quase 100 anos de críticas, debates e desdobramentos, a contribuição teórica e dimensão totalizante do Ensaio da Dádiva continuam incontestáveis e suas influências estão em todo o lugar.

Smartphone addiction as a barrier to intrinsic motivation: The role of task value and self-efficacy
Authors: Şen Şenol
Published: February 2025

This study aimed to investigate the relationships between intrinsic
motivation, self-efficacy, task value, and smartphone addiction. To examine
the relationship between smartphone addiction and intrinsic motivation, a
mediation model was developed, in which self-efficacy and task value acted
as mediating variables. The Smartphone Addiction Scale and Motivated
Strategies for Learning Questionnaire were administered to 534 high school
students to collect data. The results revealed statistically significant
negative relationships between smartphone addiction and students' intrinsic
motivation, self-efficacy, and task values. Additionally, self-efficacy and
task value were found to be possible mediators within the model. These
findings suggest that smartphone addiction may lead to a decrease in
students' intrinsic motivation by reducing their self-efficacy and task
value. In conclusion, although smartphone use enhances our daily lives, it
may also have negative effects on certain affective variables that play an
important role in the learning process, as demonstrated in this study.
Heat and mass transport characteristics in viscous slip flow over a curved surface and entropy production
Authors: Olkha Amala , Choudhary Rahul , Kumar Mukesh
Published: February 2025

This study deals with heat and mass transport in viscous slip flow over a
curved, permeable sheet stretching linearly in a porous medium. Various
factors influencing heat and mass transport, such as non-uniform heat
generation/absorption, thermal radiation, chemical reaction, and viscous
dissipation, are invoked in the study. Under appropriate similarity
transformation relations, the governing nonlinear PDEs are turned into ODEs
in non-dimensional form, and then tackled numerically utilizing MATLbased
bvp4c technique. The impacts of pertinent parameters are exhibited
graphically on various relevant fields (velocity field, temperature field,
concentration field) and discussed. Second law analysis is also presented in
terms of entropy generation. Moreover, values of skin friction coefficient,
Nusselt number, and Sherwood number are computed and presented in tabular
form. For validity of the results obtained, the skin friction coefficient
values are compared with previously published data and found to be in good
agreement.
Study on the typical influencing factors of gasoline vapor explosion in a confined space
Authors: Li Run , Cheng Yang-Fan , Zhu Rong-Kang , Chen Zi-Han , Xu Jian-Wei
Published: February 2025

To explore the influencing factors of explosion accidents caused by gasoline
leakage in a confined space, the effects of ignition delay time, ignition
energy, initial pressure, initial temperature and mass concentration on
gasoline vapor explosion pressure and flame propagation velocity were
investigated using a 20 L spherical explosion vessel. The dynamic explosion
temperature distribution of gasoline vapor was mapped by the colorimetric
thermometry, and the results demonstrated that the optimal ignition delay
time, ignition energy and mass concentration of gasoline vapor in the
confined space were 100 ms, 100 J and 160 g/m3, respectively. When the
initial pressure was 0.11 MPa, the deflagration pressure of gasoline vapor
explosion reached the maximum of 1.08 MPa. The influence of the increasing
initial temperature on the maximum explosion pressure rise rate of gasoline
was greater than that on the explosion pressure and combustion duration.
When the mass concentration of gasoline vapor was 160 g/m3, the flame
propagation velocity and average temperature both obtained their maximum
values of 1.23 m/s and 2271 K, respectively. The research results were
conductive to reveal the mechanism of explosion accidents caused by gasoline
leakage in a confined space, and may provide theoretical guidance for safe
storage and transportation of gasoline.

Published: February 2025

This study conducts an experimental and modeling investigation on the
optimization of the glass fiber filter diversion structure. Addressing the
critical issue in air filtration systems of enhancing the service life and
performance of filter devices, this research rationally designs and
optimizes the structural parameters of the diversion structure. Numerical
simulation of the filter device was established through airflow organization
experiments of glass fiber filters to explore the impact of various guide
vane structure parameters on the system's air distribution uniformity and
service life. Furthermore, machine learning was employed to optimize the
guide structure of the filtration device based on the results of numerical
simulations. The study demonstrates a good agreement between numerical
simulation results and experimental outcomes, with an error of less than
10%. The optimal length and angle of the guide plate predicted by machine
learning are 163.2 mm and 38.5?, respectively. This research not only
injects new momentum into the continuous advancement of air filtration
technology but also shows significant potential in energy efficiency and
cost control.
Om lesepraksiser i den norske barnehagen
Authors: Hoel Trude , Fodstad Cecilie , Bjorvand Agnes-Margrethe , Stangeland Elisabeth Brekke
Published: February 2025

Målet med denne studien er å få innsikt i lesepraksiser i norske barnehager slik de kommer til uttrykk i en nasjonal spørreundersøkelse og fem semistrukturerte fokusgruppeintervju med barnehagelærere. I studien forstår vi lesepraksiser som sosiale, og de beskrives i form av interaksjoner mellom individer og deres omgivelser. Studien har fire fokusområder: initiativ til lesing, gruppeinndeling, avsatt tid til lesing og lesested. Sentrale funn er at: (1) Lesing i barnehagen som regel er spontan og barneinitiert. (2) Gruppeinndeling med planlagt og organisert lesing synes å være vanligere på storbarns- enn på småbarnsavdeling. (3) Det er mindre avsatt tid til lesing i form av faste tidspunkt med de yngste enn med de eldste barna. Og at (4) tilgang til eller mangel på gode lesesteder og bøker påvirker barnehagenes lesepraksiser i vesentlig grad. Basert på resultatene konkluderes det med at den vanligste lesepraksisen i norske barnehager er spontan, barneinitiert og i liten grad planlagt, noe som peker mot et behov for å revitalisere prioriteringen av lesing sammen med barnehagebarn. 
ENGLISH ABSTRACT
On Reading Practices in Early Childhood Education and Care Institutions in Norway
The aim of this study is to gain insight into reading practices in Early Childhood Education and Care (ECEC) institutions in Norway as expressed in a national survey and five semi-structured focus group interviews with early childhood teachers. In this study, we understand reading practices as social, and they are described in terms of interactions between individuals and their surroundings (Barton, 2006, p. 29). The study has four focus areas: initiative to read, group division, time set aside for reading and reading spaces. Key findings are that: (1) Reading in ECEC is usually spontaneous and child initiated. (2) Division into groups with planned and organized reading seems to be more common for the oldest than for the youngest children. (3) There is less time set aside for reading in the form of fixed times with the youngest than with the oldest children. And that (4) access to or lack of good reading spaces and books significantly affects the reading practices in ECEC. Based on the results, it is concluded that the most common reading practice in Norwegian ECEC is spontaneous, child initiated and to a small extent planned, which points to a need to revitalize the prioritization of reading together with children.
Mellom skrifta og barnet – tre barnehagelærarar sine strategiar i høgtlesing av bildebøker med få ord og med fleire ord
Authors: Vadstein Anne Marta Vinsrygg
Published: February 2025

Denne studien går ut på å utforske korleis skriftmengde påverkar tre barnehagelærarar sine val av bildebok, og kva strategiar dei tek i bruk når dei realiserer bildebøker med få ord og med fleire ord for fireåringar i barnehagen. Det empiriske materialet i studien er todelt: (1) Tre barnehagelærarar har filma to lesestunder kvar – ei bok med få ord og ei bok med fleire ord, og (2) deretter har eg gjennomført videostøtta samtalar med barnehagehagelærarane der dei reflekterer rundt førebuing og gjennomføring av lesestundene. Videoopptaka frå høgtlesingane er transkriberte og analyserte komparativt med den skrivne teksten i bøkene, og tematisk, etter kva strategiar barnehagelærarane brukar i realiseringa av verbalteksten. Tre hovudkategoriar er identifiserte: (a) invitasjonar til samtale, (b) innhaldsformidling og (c) språklege tilpassingar. Lydopptaka frå den videostøtta samtalen med barnehagelærarane i etterkant er tematisk analyserte (Braun & Clarke, 2006). Studien viser at barnehagelærarane nyttar fleire strategiar for å byggje bru mellom verbalteksten og barna når dei les bildebøker med få ord, enn når dei les bildebøker med fleire ord. Funna gir innsikt i kva rolle skriftmengde spelar for barnehagelærarar sine bokval og strategiar dei brukar i realiseringa av verbalteksten. 
ENGLISH ABSTRACT
Between the Verbal Text and the Child – Three ECEC Teachers’ Strategies Mediating Picture Books With Shorter or Longer Verbal Text
This study explores how text volume impacts three early childhood teachers’ picture book selection and their strategies for mediating books with fewer words or more words for four-year-olds. The research utilizes two forms of empirical material: (1) Three ECEC teachers have filmed two reading sessions each – one of a book with fewer words and one book with more words, and (2) video-supported conversations with the teachers, offering reflections on the reading sessions. The data from the readings was transcribed and comparatively analyzed with the book’s written text, and thematically categorized (Braun & Clarke, 2006) based on the mediation strategies utilized. The audio from the conversations was transcribed and included in the analyses. Three main strategies have been identified: (a) conversational initiations, (b) content dissemination, and (c) linguistic adaptions. The study shows that the three teachers use strategies more frequently to build bridges between the written text and the children when reading books with fewer words. The findings provide insight into the role the amount of text plays in early childhood teachers’ picture book selection and their strategies for mediating written text.
Nordic Preschool Teachers’ Views of the Physical and Psychological Literacy Environments Regarding Read-Alouds
Authors: Alatalo Tarja , Magnusson Maria , Norling Martina
Published: February 2025

This research aims to increase knowledge about how preschool teachers in three Nordic countries view their preschool’s physical and psychological literacy environment regarding read-alouds. A total of 222 Nordic preschool teachers (52 Finnish, 91 Norwegian, and 79 Swedish) responded to a survey about early literacy practices. Likert-scale questions that contained statements about teachers’ views of the physical literacy environment and methods of reading aloud were used. Scales indicating a physical and psychological literacy environment were created based on statements that reflected the respective literacy environment. The results revealed that the teachers, on average, rated their preschool’s physical literacy environment positively. Their attitudes towards the psychological literacy environment were, on average, high regarding reading aloud as an opportunity for meaning-making and even higher for language-stimulating interaction. The attitudes towards reading aloud to organise everyday activities scored very low on average, which was a somewhat unexpected finding. There were some statistically significant differences in the measures between countries and groups, such as educational level. Emphasising high-quality literacy environments as early as for one- to three-year-old children is discussed as being essential in preschool teacher training and in-service training.
Children’s literature as coupling point between global sustainability concerns and children’s local agency
Authors: Kolmos Marie , Skyggebjerg Anna Karlskov , Nielsen Anne Maj
Published: February 2025

This article is about how educators’ dialogical–creative presentation of children’s picture books has the potential to make global sustainability concerns accessible to young children. Thematization around climate change and the biodiversity crisis are global phenomena that are difficult to translate to the local settings where children spend part of their lives. This article argues that various dialogical and creative reading activities based on relevant children’s literature may serve as gateways to developing young children’s agency and understanding related to some of the sustainability concerns that they may have to address when they grow up. This article’s analysis is based on two literature courses at a Danish early childhood education and care centre, where educators invited children to creatively explore literary narratives in various ways, through visits to the surrounding area and the creative processing of the stories’ message. The analyses show how children’s potential agency is developed through a dialectical process of becoming based on a sociocultural and phenomenological understanding of artefacts, mediating means and place as an event.

Interpretación del bienestar y calidad de vida de becarios del programa Jóvenes Construyendo el Futuro a partir de características personológicas
Authors: Moreno-García Blanca Verónica , Beltrán López Robert , Díaz Rodríguez Eustacio , Moreno Cuahteconzi Francisco Javier
Published: February 2025

La presente investigación tuvo como escenario de estudio el municipio de Othón P. Blanco, Quintana Roo, México; el objetivo consistió determinar las características personológicas de los individuos que acceden al programa social Jóvenes Construyendo el Futuro en Othón P. Blanco con base en su interpretación del estado de bienestar personal y calidad de vida, considerando que la importancia de la variable que se estudiada, condicionó directamente su interpretación de la realidad y como consecuencia en su modelo del mundo. Esto puede determinar su calidad de actuación en lo individual y en lo colectivo y contribuir al mejoramiento de las condiciones de vida y evitar conductas no deseables, como la violencia, las adicciones y las actividades delictivas, que son reflejo de la marginación y desigualdad social. Se fundamentó en el modelo de desarrollo humano de Sen y Ul Haq, el modelo de bienestar de Ryff y la Teoría de personalidad de Fromm. Se parte de una epistemología interpretativista-crítica, que busca comprender el sentido subjetivo de las experiencias humanas desde una perspectiva crítica, con un paradigma fenomenológico-hermenéutico, utilizando para el efecto la entrevista autobiográfica narrativa con enfoque de historia de vida. Se realizó un muestreo intencional por experiencia. Los resultados indican que, sí se percibe bienestar a partir del apoyo social; sin embargo, existen dos perspectivas, una con creencias mercantilistas bajo la perspectiva de tener más si se puede, y otros bajo la creencia de una política benefactora de acceder a aquello a lo que no se puede. Concluyendo que, los programas sociales, como políticas públicas, son efectivos para promover la equidad y la igualdad de oportunidades. Sin embargo, deben complementarse con estrategias que fomenten valores individuales y sociales, para prevenir prácticas de corrupción y simulación, contribuyendo así al fortalecimiento de una sociedad más justa y sostenible.

Based on multi-method team ethnography, this study examines the knowledge production of creative ethnographic methods. We explore what the encounters between ethnographers and streets as sensory entities can tell us about urban living: How do ethnographers become part of street life, and what kind of knowledge is produced through this material-sensory entanglement? Our experimental methods include ethnographic hanging out, sensory intervention, and the application of ethnographic methods in futures studies. These methods broaden our understanding of the ways in which the socio-material environment can be experienced and envisioned. They shift attention to the blind spots, offering a unique perspective on urban life that diverges from traditional depictions of street life. Our project draws inspiration from a 1970s ethnological project in which two streets in central Helsinki were documented by ethnology students through interviews, photographs, and observations of street and domestic life. In autumn 2023, present-day ethnology students revisited the same streets using sensory and creative ethnographic methods as their tools. This knowledge is reflected in the research ideals of the 1970s and the knowledge produced at that time.The article is based on the coursework conducted in the Ethnography of Everyday Life course in autumn 2023.
