Juguetes científicos para enseñar física y química. Ejemplos de su uso en Educación Primaria
Authors: Montejo Bernardo José Manuel
Published: February 2023

La ciencia, o mejor dicho, la divulgación científica está de moda, gracias sobre todo a los programas televisivos, y eso ha hecho que los denominados juguetes científicos se hayan hecho un hueco entre los juegos de mesa, las videoconsolas y los drones. Sin embargo, su uso con fines divulgativos no es algo nuevo y desde hace años se vienen publicando muchos trabajos en los que se describen los principios científicos por los que se rige su funcionamiento y se muestran sus posibilidades como medio para la difusión de la ciencia de un modo lúdico. También han sido propuestos como una herramienta innovadora para la enseñanza de la física y la química en diferentes niveles educativos, fundamentalmente a partir de la ESO y hasta la Universidad. En muchos casos la explicación técnica de su funcionamiento no es sencilla y eso limita su aplicación para niveles educativos más bajos, de modo que en los trabajos en los que se propone su uso para los niveles de primaria se presentan más como un recurso para estimular el interés del alumnado que como una herramienta para emplearla directamente en las clases. En el presente trabajo se repasan y analizan brevemente estas cuestiones y se presentan una serie de propuestas con ideas y ejemplos sobre cómo se pueden emplear este tipo de juguetes en las clases de física y química en los cursos de Educación Primaria.
EMOROBOTIC: Gestión Emocional a través de la Programación en Robots en Educación Primaria
Authors: López Ramos Víctor , Yuste Tosina Rocío
Published: February 2023

¿Puede un niño de 11 años aprender a programar un robot para que éste sea capaz de dar respuestas emocionales con las que ambos interactúen? Esta es, en la más absoluta puridad, la pregunta que se plantea el presente proyecto de investigación. Una pregunta sencilla, concreta y concisa. El proyecto EMOROBOTIC pretende analizar la utilidad y relevancia de la programación de emociones en robots, investigando de esta forma varios núcleos de conocimiento: el aprendizaje por parte de niños de entre 10 y 12 años de la gestión emocional, de la programación computacional, de las estrategias básicas de trabajo colaborativo, y de las implicaciones y repercusiones que puede tener este aprendizaje en el currículo de Educación Primaria. EMOROBOTIC se constituye como un proyecto claramente multidisciplinar, integrado por profesionales de la docencia en los niveles de la Educación Primaria, secundaria y universitaria, así como de la empresa privada, asociaciones y fundaciones extremeñas, cuyas procedencias académicas y profesionales son tan variadas como las diferentes áreas que pretende estudiar, conformando así un amplio equipo de trabajo especialmente diverso e innovado.

Analytical study on behaviour and performance of infilled frame structure with reinforced eccentric opening
Authors: Wirawan Putu , Wiryadi Gede , Tubuh Ketut , Pradnyadari Ni
Published: February 2023

This numerical analysis has discussed the behaviour of the frame structure with eccentric infill wall opening modelled with shell and strut elements. In the beginning, validation models were created by following the laboratory tests results. Then, a simple one-storey infill frame structure with an opening was modelled with varying ratios by taking the strut angle formed to obtain an equation for the strut width that corresponds to the behaviour of shell element model with strut angles variation. The strut width equation was then applied to the 3-storey infill frame structures. The behaviour comparison between the strut and shell element model was then investigated by linear and nonlinear static analysis. The strut width equation for infill wall frame with eccentric openings (Weo) is determined by modifying the stiffness coefficient (Ce) based on the opening ratio. The application of the Weo equation to the infill frame model showed that the strut model had a comparable behaviour to the shell element model. The drift ratio comparison showed that the smaller the strut angle, the greater the structure stiffness. The pushover analysis shows the infilled frame model was able to withstand a larger base shear force than the open frame model.
When workers feel like objects: A field study on self-objectification and affective organizational commitment
Authors: Valtorta Roberta Rosa , Monaci Maria Grazia
Published: February 2023

Objectification is a form of dehumanization that implies the perception of others as mere objects. The present study aimed to expand research on objectification in the work domain by exploring the relationships between objectifying job features, self-objectification, and affective organizational commitment within a real work setting. Building on previous literature, we hypothesized that the execution of objectifying work activities would be positively related to workers’ tendency to objectify themselves. Further, we expected a decrease in affective organizational commitment as the outcome of these perceptions. A study involving 142 Italian supermarket clerks (75 females) supported our hypotheses. Workers with a low-status job role (i.e., cashiers and salespeople vs. managers) perceived their activities as more objectifying. In turn, this perception heightened their self-objectification, which decreased workers’ commitment towards the organization. Our results enrich the understanding of workplace objectification by also providing relevant insights into the link between social-psychological and organizational processes.
A systematic review of adolescent flourishing
Authors: Waigel Nicole C. , Lemos Viviana N.
Published: February 2023

Traditionally, the study of well-being has been approached from the hedonic and eudaimonic perspectives. However, the last findings suggest that both aspects are complementary, giving place to an integrated conceptualization of well-being called flourishing. In spite of the constant increase of research around this construct, there is still little information regarding flourishing in adolescents. The objective of this study is to review the available literature on flourishing in adolescence in relation to its tie with other constructs, its study in different contexts and the way it has been operationalized. The selection of the studies was conducted in two phases. First, it was verified that the exclusion and selection criteria were met. Then, an evaluation of the quality of the pre-selected studies was carried out. The data were synthesized through the thematic synthesis method. For the results, 28 empirical studies were selected. Four thematic axes were identified: (a) Flourishing in different contexts, (b) Flourishing in regards to other results and positive psychological characteristics and/or their negative counterpart, (c) Flourishing and psychosocial vulnerability, and (d) indicators for the evaluation of flourishing. Suggestions are provided with the goal of consolidating the science of human flourishing.

Published: February 2023

As meias compressivas são produzidas, principalmente, para tratar e melhorar a vida das pessoas com doenças venosas e problemas circulatórios. O presente estudo teve como objetivo identificar os parâmetros para o design de meias compressivas, a fim de compreender e demonstrar a imprescindibilidade dos estudos de usabilidade para o desenvolvimento do produto e da contribuição do design, enquanto um campo interdisciplinar, em melhorar a qualidade dos produtos. Tais parâmetros foram obtidos por meio de uma investigação de uso que ocorreu pela aplicação de um questionário eletrônico, a 122 usuários ativos de meias compressivas. A pesquisa identificou o perfil do usuário e foram analisadas algumas questões referentes à usabilidade: percepção de eficácia do produto, satisfação de uso, agradabilidade visual, aceitação social e a capacidade de vestir.Como resultado, foi possível destacar também os motivos quanto às insatisfações do usuário para com o produto, tais como desconforto térmico, descontentamento quanto à gama de cores disponíveis no mercado, e dificuldade no ato de vestir o produto. Assim, este artigo contribui para o projeto de meias de compressão e enfatiza a necessidade de pesquisas que incentivem produtos mais ergonômicos, inclusivos e adaptáveis.

Desaprender, perguntar-se, escutar: rotas para pensar uma arte educação dissidente
Authors: Wosniak Fabio
Published: February 2023

O presente artigo apresenta os percursos do autor na construção de propostas pedagógicas dissidentes, envolvendo articulações entre a prática artística e a prática docente na Licenciatura em Artes Visuais. Para propiciar aos acadêmicos/as estas experiências, foram pensadas aulas onde teoria e prática não se dissociavam, mas que se nutriam constantemente. As fragmentações como arte e vida, educação e arte, agir e pensar, foram todas colocadas entre parênteses. A provocação para pensar a arte e a arte educação dissidente, partia sempre das inquietações cotidianas, que logo encontravam nas metodologias utilizadas pelos/as artistas uma outra questão-problema para ser pensada. Nestes caminhos, com as des-aprendizagens a partir do trabalho do artista e da sua prática, foi possível compreender que um percurso era certo: descontruir saberes, perguntar mais que responder, aprender a ouvir o que as práticas artísticas dissidentes estão clamando e, só a partir desta outra maneira de des-aprender sem repostas absolutas e verdadeiras, se torna possível reconstruir saberes.
Imagens da memória: experiências afetivas de uma professora/artista
Authors: Schvambach Janaina
Published: February 2023

O texto apresenta um trecho de minha tese de doutorado em que conto por meio de ensaios poéticos minhas experiências estéticas e sensíveis que reverberaram em minha prática docente enquanto professora de fotografia e como artista visual no uso da fotografia. A tese, defendida em meio a pandemia no ano de 2020, utilizou-se do método da cartografia e a coleta de dados teve como dispositivo fotografias publicadas em um perfil pessoal na rede social Instagram em forma de arquivo/diário. O perfil, criado no início do doutorado, possuía inicialmente o objetivo registrar o dia a dia do processo de doutoramento. Porém, acabou se tornando um arquivo do meu olhar durante os quatro anos. Por meio dele armazenei imagens que me tocavam ou rememoravam um passado distante que se fazia presente a todo momento. Assim, como uma viajante flâneur, naveguei entre as águas da memória, marcadas por um olhar delicado que se efetiva por meio da fotografia, trazendo os afetos que atravessaram/atravessam e constituíram/constituem minha subjetividade. Através das imagens, criei narrativas e neste momento, apresento algumas histórias, noções e conceitos que balizaram a pesquisa.
Fotografias de Berenice Abbott e Gisèle Freund: troca de olhares entre mulheres que amavam mulheres
Authors: Auler Lívia Bittencourt
Published: February 2023

O presente artigo apresenta retratos de mulheres que se relacionaram afetivamente com outras mulheres, através do trabalho de duas fotógrafas lésbicas: Berenice Abbott e Gisèle Freund. As fotografias de ambas as artistas foram feitas principalmente dentro do círculo artístico europeu, sobretudo parisiense, durante a primeira metade do século XX. Além de dissertar sobre as fotógrafas e suas produções, também serão comentados aspectos da vida e obra de cada retratada; entre elas estão as artistas e escritoras Marie Laurencin, Colette, Djuna Barnes e Janet Flanner. A partir desta pesquisa, foi possível observar a relevância da criação de laços entre essas mulheres, explicitados pela troca de olhares entre fotógrafa e fotografada, para a sustentação de um senso de comunidade e construção de identidade entre mulheres lésbicas. Dessa forma, este artigo procura ampliar a reflexão sobre o tema na historiografia da arte e reafirmar a importância de visibilizar os relacionamentos entre mulheres, os quais, por muito tempo, foram largamente ocultados.

Notas sobre a educação feminina nos primeiros liceus de Artes e Ofícios em Porto Alegre: entre poética, técnica e formação
Authors: Acom Ana Carolina , Bosak Joana
Published: February 2023

A educação feminina em Liceus, no Rio Grande do Sul, foi desenvolvida desde o século XIX, mas principalmente sob a égide do Estado, no início do século XX. A pesquisa bibliográfica e documental buscou encontrar relações entre a formação feminina e o ensino em artes e ofícios. A investigação em teses, dissertações, artigos e jornais de época evidenciou a marca permanente do currículo voltado à formação limitada ao horizonte doméstico. Dessa forma percebemos em relações com a literatura e o cinema a manutenção de padrões de comportamento e inserção feminina fixos, nos quais a questão do gênero aparece sempre marcada pela domesticidade e cuidado com a casa e filhos.
A educação e a indústria do vestuário no nordeste catarinense: do aprendizado informal ao ensino profissionalizante
Authors: Riffel Renato , Schmitt Darlan Jevaer , Theis Mara Rubia , Schaefer Egéria Höeller Borges
Published: February 2023

A presente pesquisa objetiva delinear um panorama histórico da educação profissionalizante e da formação da mão de obra para a indústria do vestuário nas cidades de Blumenau, Brusque e Jaraguá do Sul. A pesquisa bibliográfica e documental apresenta um recorte temporal entre 1850, período que compreende o início da colonização do nordeste catarinense, e se estende até 2004, momento em que ocorre a consolidação do ensino superior na área de moda nas cidades citadas. O estudo abrange a capacitação informal de aprendizes, como alfaiates e costureiras domésticas, as políticas públicas voltadas para a formação profissional e, sobretudo, a constituição do ensino profissionalizante na área da indústria do vestuário organizado a partir da composição da Federação das Indústrias do Estado de Santa Catarina (FIESC) e do Sistema “S”, acompanhando demandas do desenvolvimento industrial do Estado. Diante da industrialização, o ofício de alfaiate perdeu sua função social, mas seus métodos de modelar, cortar e costurar as roupas multiplicaram-se em materiais didáticos e no processo ensino e aprendizagem que capacitam estudantes e professores. Entende-se que o sistema educacional profissionalizante deve abranger o desenvolvimento intelectual, qualificação profissional e formação cidadã. A educação não pode se limitar às soluções para as demandas do mundo do trabalho, mas sim, ser parte ativa da construção desse mundo primando pela humanização nos processos de ensino e aprendizagem, para que se perpetuam no contexto político, econômico, social e profissional.
O ensino profissional em Florianópolis: entre cortes, costuras e algumas agulhadas
Authors: Sant'Anna Mara Rúbia
Published: February 2023

O ensino profissionalizante no contexto da capital catarinense e a partir do período republicano é o tema de pesquisa que fomentou a escrita desse artigo. Seu propósito foi refletir em que medida as diferentes modalidades de ensino profissionalizante praticadas em Florianópolis, de inciativa pública, atentou para o perfil socioeconômico da sociedade local, em especial, as formações voltadas para o universo da produção e consumo do vestuário. Para alcançar tal objetivo foram arroladas fontes primárias como legislação estadual e anúncios de jornais e, igualmente, teses, dissertações e publicações diversas que trataram do tema, época e sociedade. Dada a vasta problemática definida, a delimitação temporal foi estabelecida entre 1910 e1993. Após análises, se concluiu que os projetos educacionais profissionalizantes adotados não eram atentos à realidade socioeconômica e nem mesmo ao projeto de desenvolvimento local definido pela gestão estadual, cuja razões dessas decisões se devem a própria compreensão do que é o sistema produtivo do vestuário e o status social desfrutado por seus profissionais.

Caracterização e viabilidade técnica de aplicação de tijolos ecológicos em habitações populares: uma contribuição à sustentabilidade ambiental
Authors: Barcelos Sheyla Thays Vieira
Published: February 2023

O crescimento populacional e o aumento no número de indústrias no Brasil acarretaram maior geração de resíduos. Um exemplo são as usinas sucroalcooleiras, que vem aumentando sua produção e com isso a preocupação com uma destinação final correta aos resíduos. Este artigo caracteriza amostras de cinza de bagaço de cana-de-açúcar (CBC) e composto (mistura de cinzas e torta de filtro) afim de produzir e avaliar a viabilidade técnica de tijolos ecológicos, propondo uma proporção adequada para adição desses materiais alternativos na fabricação de tijolos que possam ser aplicados em habitações populares, obedecendo os padrões estabelecidos por norma. As produções de tijolos ecológicos foram realizadas nos traços 1:1:5, 1:2:4 e 1:3:3 (cimento: resíduo: solo), assim como um traço controle de 1:6 (cimento: solo). As amostras de cinzas e composto foram caracterizadas através de granulometria, compactação, atividade pozolânica, DRX e FRX, enquanto os tijolos fabricados foram testados quanto a resistência a compressão, umidade e absorção de água. As amostras testadas se mostraram promissoras para utilização como agregado miúdo na produção de tijolos. Apesar de somente a amostra de cinzas ter apresentado resultado satisfatório para atividade pozolânica, os traços 1:1:5 com ambos os resíduos e 1:2:4 com composto, tanto para os ensaios de resistência à compressão quanto para absorção de água, se mostraram satisfatórios resultando em 4,25 MPa e 15,58% para o traço 1:1:5 com CBC, 4,25 MPa e 14,88% para o traço 1:1:5 com composto e 1,99 MPa e 19,21% para o traço 1:2:4 com composto, atendendo o mínimo estabelecido pela NBR 8491 (2013) para o uso de tijolo solo-cimento-resíduo. Os subprodutos serão reutilizados dentro do contexto de economia circular e dos pilares da sustentabilidade, evitando o descarte na natureza. Além dos benefícios ao meio ambiente, amplia de forma desejável o espectro da construção civil, possibilitando sua aplicação em imóveis populares, fomentando o desenvolvimento local do estado do Mato Grosso do Sul e diversificando as possibilidades de execução, sendo possível a aplicação em proporção adequada da cinza ou composto, que não haviam sido estudados em conjunto até o momento.
Effects of Household Chaos on Preschoolers’ Aggression and Prosocial Behavior: Sleep Problems and Executive Function as Mediators
Authors: Lee Bomi , Noh Jeeun , Shin Nana
Published: February 2023

Household chaos, represented by high levels of disorganization and instability in the home, has been linked with suboptimal outcomes for preschoolers. The aim of this study was to examine the roles that sleep problems and executive function play in the association between household chaos and preschoolers’ aggression and prosocial behavior. The sample for the study consisted of 420 preschoolers and their mothers. The mothers provided reports on the level of chaos in the home and their preschoolers’ sleep problems, executive function, and social behavior, including aggression and prosocial behavior. The data was analyzed using structural equation modeling. When preschoolers’ sleep problems and executive function were included in the model as mediators, the results indicated that household chaos did not have direct effects on preschoolers’ aggression and prosocial behavior. Such effects were instead serially mediated by preschoolers’ sleep problems and executive function, respectively. The higher the degree of household chaos, the more preschoolers displayed sleep problems and deficits in executive function, resulting in more aggression and less prosocial behavior. The findings from this study emphasize the significance of reducing household chaos in order to reduce preschoolers’ aggression and promote prosocial behavior. They also underscore the need to identify additional variables that mediate the impact of household chaos on preschoolers’ social outcomes.
A Case Study of the Use of Artificial Intelligence in a Problem-Based Learning Program for the Prevention of School Violence
Authors: Shim Jae Young , Choi Saeeun
Published: February 2023

The aim of this study was to develop, implement, and evaluate the use of Artificial Intelligence in the prevention of violence among middle-school students. The sample for this study consisted of 20 first-year middle-school students who participated in theme selection activities in a free semester program as part of their home economics studies. The data for the study consisted of nine class observation logs, four group activity outputs, 30 class results, an online survey, and in-depth interviews with three students. A program called “R.U.OK” was developed by setting problematic situation for school violence prevention linked to the contents of the Home Economics Education(HEE) curriculum. After the program was implemented, the survey on the students’ class satisfaction content elements, with AI-based learning activities and PBL and interest, displayed high points, with an average of 4.0 or higher. Our qualitative analysis produced four significant results. First, students’ concerns about school violence had increased and they showed a change in attitude, having more empathy with friends and more interest in their surroundings. Second, digital and AI literacy had improved, and students’ interest in digital media learning had increased. Third, there had been an improvement in problem-solving ability in terms of being able to think more critically and independently. Fourth, the results also demonstrated that there had been a positive effect on self-direction and an improved capacity for teamwork. This study was significant in demonstrating the effectiveness of a program for the prevention of school violence based on the use of digital technology in the educational environment.
Physical Education in primary schools: head teachers' beliefs and practices
Authors:   , Williams Sarah
Published: February 2023

This study investigates primary school head teachers’ beliefs about Physical Education (PE). It illustrates significant ways in which head teachers’ personal and professional experiences shape their beliefs about PE and the ways in which PE is conceptualised in schools. In so doing, this research has been designed to develop an understanding of the factors that have shaped the participants’ beliefs and practices in PE, thus strengthening the existing knowledge and understanding within the field. The research is situated within an interpretivist framework in order to understand the subjective experience of primary head teachers. Moreover, the research follows a sequentially timed, explanatory mixed methods model to gain a pragmatic understanding of the participants’ experiences. The thesis presents an argument that, after many years on the side-lines of the primary curriculum, a critical period for the positioning and development of PE has been reached, whereby a careful, objective evaluation needs to take place to protect and secure the educational integrity of PE. Moreover, it is argued that, if PE is going to meet the needs of children, it is essential to question the ways in which PE is conceptualised and taught in primary schools. This would assist the refocusing of PE’s educational goals. It is, therefore, important for head teachers to understand the unique subject goals and pedagogies of PE and acknowledge the somewhat contradictory messages that have accompanied recent policy. Currently, research on primary head teachers’ beliefs and practices the factors that have shaped their conceptualisations of PE is limited. Hence this research addresses an established gap in the body of knowledge. The findings illustrate significant ways in which head teachers’ personal and professional experiences shape their beliefs, conceptualisations and practices in PE. Drawing on Lawson’s model of teacher socialisation (1983a, 1983b), this research serves to reinforce the importance of effective initial and early career teacher continuous professional learning for generalist primary teachers in PE to ensure pedagogical practice in PE is aligned with other areas of the curriculum. This study reinforces the vital role of head teachers in developing and leading a school culture that models positive health practices and motivates learners to become lifelong participants. In order to fulfil this role effectively, it is imperative that head teachers understand the unique contribution and educational value of PE and are able to clearly articulate the purpose of PE to ensure it is taught in a way that is educative. The findings of this research have led to the development of several recommendations including professional learning opportunities and materials to support headteachers to consider the unique contribution and educational value of PE and the provision of high-quality Initial Teacher Training experiences including opportunities to teach PE during school-based training.
The Effectiveness of Soft Skills in Generating Dynamic Capabilities in ICT companies
Authors: Ogunrinde Abayomi
Published: February 2023

Purpose: This article aims to show the effectiveness of soft skills to increase the dynamic capabilities of information and technological companies. The research was carried out to examine the effects of soft skills in ICT firms located in European Countries. Results obtained from various projects such as Skills Match, research sources show that 86% of respondents indicate an increased emphasis on soft skills and that organizations now consider soft skills more important than employees.
Design Methodology: The article try to show that ICT firms with employees with a high level of soft skills derive dynamic capabilities than those with employees with deficit soft skills. The search was conducted through the scientific databases: Web of Science and Scopus; with specific journals, articles, book chapters, and reports. The search then narrowed to some specific subject areas. The search span was from 2016-2020.
Contributions: Based on the search results, the literature was synthesized, and the importance of soft skills to generate dynamic capabilities in ICT firms were identified. Soft skills are not only necessary for work; they are vital for daily living.
Practical Implications: This study showed that there is a wide range of soft skills that the employers and staff of ICT companies should possess to be successful.
Added Value: The implication of this article is that firms can no longer take with levity acquisition, training and continuous development of soft skill if it is generating dynamic capabilities.
Increasing Pathways to Leadership for Black, Indigenous, and other Racially Minoritized Women
Authors: Motapanyane Maki , Shankar Irene
Published: February 2023

Leadership positions within post-secondary institutions (PSIs) remain elusive to women generally, and to Black, Indigenous, and other racially minoritized women in particular. In this paper, we argue that pathways to leadership, particularly for non-traditional, non-normative and critical approaches that can come from the differently situated epistemic positioning of Black, Indigenous, and other racially minoritized women, are important as beginning steps towards progressively dismantling standardized Eurocentric, androcentric, and corporatized academic workplace cultures. This type of reform is essential preliminary work in the process toward greater equity and inclusivity in academic institutions. Note then that we are writing of a significant amount of substantive change needed to enact crucial initial reform, in tandem with, and beyond which we should continuously push for more radical transformation (Dryden 2022; Patel 2021). As such, we propose initiatives that universities can take to address some of the common gendered, racialized, and class-related exclusions and inequities evident in academic workplaces. This is in acknowledgement that academic institutions, having demonstrated a predilection for the co-optative and performative, are barely able to reform meaningfully, let alone engage the “transformation” and “decolonization” with which reform is often confused and erroneously conflated. Grounded within institutional research, we detail the commitments required from governing bodies, the changes necessary in academic decision-making spaces, the need for timely and transparent data collection infrastructure, and other institutional changes required to enhance the recruitment, hiring, and retention of Black, Indigenous, and other racially minoritized faculty and academic leaders. Together, these practices constitute preliminary reform necessary to create opportunity for more meaningful practices of inclusion.
Trauma-informed Consent Education: Understanding the Grey Area of Consent Through the Experiences of Youth Trauma Survivors
Authors: Wright Jessica
Published: February 2023

Sexual consent education has emerged in recent years as the most popular method of preventing gender-based violence. Yet, the concept of consent used in much contemporary programming problematically oversimplifies sexual exploration and the power dynamics it is imbued with by asserting that consent is as simple as “Yes” or “No.” The messiness of sexual negotiation or the ‘grey areas’ of consent that youth may experience are left unaddressed. By examining the experiences of youth trauma survivors through a trauma-informed lens, the limits to binary consent education become clear. I draw on empirical data from nine open-ended interviews with Canadian youth trauma survivors to demonstrate how a trauma-informed lens may be implemented in consent education. I argue that educators should include understandings of consent which falls outside the Yes/No binary in order to adequately address youth survivors’ vulnerability to sexual (re)victimization. I examine how three of the psychosocial impacts of trauma, dissociation, hypersexuality, and struggles with acquiescence, refuse the binaristic model of consent and should be considered for trauma-informed consent education. While education alone cannot end rape culture, addressing the grey area of consent in consent education may help reduce preventable harm for survivors, as well as youth more broadly.
Bacillus thuringiensis toxins divert progenitor cells toward enteroendocrine fate by decreasing cell adhesion with intestinal stem cells in Drosophila

Published: February 2023

Bacillus thuringiensis subsp. kurstaki (Btk) is a strong pathogen toward lepidopteran larvae thanks to specific Cry toxins causing leaky gut phenotypes. Hence, Btk and its toxins are used worldwide as microbial insecticide and in genetically modified crops, respectively, to fight crop pests. However, Btk belongs to the B. cereus group, some strains of which are well known human opportunistic pathogens. Therefore, ingestion of Btk along with food may threaten organisms not susceptible to Btk infection. Here we show that Cry1A toxins induce enterocyte death and intestinal stem cell (ISC) proliferation in the midgut of Drosophila melanogaster, an organism non-susceptible to Btk. Surprisingly, a high proportion of the ISC daughter cells differentiate into enteroendocrine cells instead of their initial enterocyte destiny. We show that Cry1A toxins weaken the E-Cadherin-dependent adherens junction between the ISC and its immediate daughter progenitor, leading the latter to adopt an enteroendocrine fate. Hence, although not lethal to non-susceptible organisms, Cry toxins can interfere with conserved cell adhesion mechanisms, thereby disrupting intestinal homeostasis and endocrine functions.
TIR-1/SARM1 inhibits axon regeneration and promotes axon degeneration

Growth and destruction are central components of the neuronal injury response. Injured axons that are capable of repair, including axons in the mammalian peripheral nervous system and in many invertebrate animals, often regenerate and degenerate on either side of the injury. Here we show that TIR-1/dSarm/SARM1, a key regulator of axon degeneration, also inhibits regeneration of injured motor axons. The increased regeneration in tir-1 mutants is not a secondary consequence of its effects on degeneration, nor is it determined by the NADase activity of TIR-1. Rather, we found that TIR-1 functions cell-autonomously to regulate each of the seemingly opposite processes through distinct interactions with two MAP kinase pathways. On one side of the injury, TIR-1 inhibits axon regeneration by activating the NSY-1/ASK1 MAPK signaling cascade, while on the other side of the injury, TIR-1 simultaneously promotes axon degeneration by interacting with the DLK-1 mitogen-activated protein kinase (MAPK) signaling cascade. In parallel, we found that the ability to cell-intrinsically inhibit axon regeneration is conserved in human SARM1. Our finding that TIR-1/SARM1 regulates axon regeneration provides critical insight into how axons coordinate a multidimensional response to injury, consequently informing approaches to manipulate the response toward repair.

Loss- and gain-of-function of MeCP2 causes Rett syndrome (RTT) and MECP2 duplication syndrome (MDS), respectively. MeCP2 binds methyl-cytosines to finely tune gene expression in the brain, but identifying genes robustly regulated by MeCP2 has been difficult. By integrating multiple transcriptomics datasets, we revealed that MeCP2 finely regulates growth differentiation factor 11 (Gdf11). Gdf11 is down-regulated in RTT mouse models and, conversely, up-regulated in MDS mouse models. Strikingly, genetically normalizing Gdf11 dosage levels improved several behavioral deficits in a mouse model of MDS. Next, we discovered that losing one copy of Gdf11 alone was sufficient to cause multiple neurobehavioral deficits in mice, most notably hyperactivity and decreased learning and memory. This decrease in learning and memory was not due to changes in proliferation or numbers of progenitor cells in the hippocampus. Lastly, loss of one copy of Gdf11 decreased survival in mice, corroborating its putative role in aging. Our data demonstrate that Gdf11 dosage is important for brain function.
Gastric Inverted Hyperplastic Polyp Removed Using Endoscopic Submucosal Dissection

Gastric subepithelial tumors (SETs) are usually asymptomatic and are often detected incidentally during screening endoscopy. A gastric inverted hyperplastic polyp (IHP) is characterized by downward growth of hyperplastic mucosa into the submucosal layer. Owing to these characteristics, a gastric IHP is frequently misdiagnosed as a SET. Gastric IHPs are asymptomatic in most cases and are discovered incidentally. Notably, IHPs may be accompanied by an adenocarcinoma or anemia owing to chronic bleeding associated with this lesion; therefore, endoscopic submucosal dissection is recommended for complete excision of IHPs measuring > 2 cm. We report a case of gastric IHP that was diagnosed during screening endoscopy in an asymptomatic patient. We observed a whitish purulent exudate expressed from the SET, and endoscopic ultrasonography revealed a SET originating from the muscularis mucosa. Endoscopic submucosal dissection was performed to remove the SET, and final histopathological findings revealed a gastric IHP. This case report highlights that IHPs should be suspected in patients with a SET associated with whitish exudates.

Background

Global shifts in climatic patterns have been recorded over the last decades. Such modifications mainly correspond to increased temperatures and rainfall regime changes, which are becoming more variable and extreme.

Methods

We aimed to evaluate the impact of future changes in climatic patterns on the distribution of 19 endemic or threatened bird taxa of the Caatinga. We assessed whether current protected areas (PAs) are adequate and whether they will maintain their effectiveness in the future. Also, we identified climatically stable areas that might work as refugia for an array of species.

Results

We observed that 84% and 87% of the bird species of Caatinga analyzed in this study will face high area losses in their predicted range distribution areas in future scenarios (RCP4.5 and RCP8.5, respectively). We also observed that the current PAs in Caatinga are ineffective in protecting these species in both present and future scenarios, even when considering all protection area categories. However, several suitable areas can still be allocated for conservation, where there are vegetation remnants and a high amount of species. Therefore, our study paves a path for conservation actions to mitigate current and future extinctions due to climate change by choosing more suitable protection areas.
Physical Characteristics of Biocomposite Edible Films Based on Fish Gelatin and Nanochitosan with the Addition of Beeswax: A Review
Authors: Fitriyanti . , Rochima Emma , Rostini Iis , Pratama Rusky Intan
Published: February 2023

Edible films is a thin layer that can be eaten directly with the food it is coated with and is biodegradable, so it is used as an alternative to plastic packaging. The components of the edible film consist of hydrocolloids (proteins and polysaccharides), lipids (fatty acids), and composites (a combination of hydrocolloids and lipids). The physical characteristics of edible films that are commonly used are thickness, tensile strength, elongation percentage, water vapor transmission rate and solubility. Several studies have shown that the addition of beeswax to gelatin and nanochitosan edible films can produce films with good physical characteristics. The addition of a greater concentration of beeswax can increase the thickness value and decrease the value of the water vapor transmission rate and water solubility of the edible film.

The maize very important role in the Brazilian economy because it has a high commercial value, having great production due to its ability to adapt to different edaphoclimatic conditions. Family farming produces seeds from local varieties, called creole seeds. This type of seed is resistant because it keeps relevant characteristics left as an inheritance from its ancestors, who, free of charge, performed an environmental service for the preservation and perpetuation of this genetic heritage. Therefore, the work had to evaluate the effect of the adherent agents palm extract, aloe vera extract and sugar solution in the pelleting of creole corn seeds with rock dust. The work was carried out in the Plant Propagation Laboratory belonging to the Campus of Engineering and Agricultural Sciences of the Federal University of Alagoas. As adherent agents were used: water, palm extract, aloe vera extract and sugar solution. Rock dust (MB-4) was used for the coating. The evaluated parameters were: water content, weight of a thousand seeds, first germination count, germination, germination speed index, average germination time, germination uncertainty, length and dry mass of the root and aerial part. Palm extract is the most efficient adherent agent for pelletizing corn seeds with rock dust.

This article highlights the findings of a study that explored girls’ issues in weekly boarding. The objectives of this research were twofold: (1) explore the problems that exist among the girls in weekly boarding at Chadiza Day Secondary School; (2) determine how problems among the girls in weekly boarding day secondary schools impede their education. This study used a mixed method research employing a case study. The study sample consisted of 38 participants: 12 girls, 10 boys, 10 teachers (5 female teachers and 5 male teachers), 2 guidance teachers, 2 administrators and 2 parents. Participants were sampled using snowball, purposive and convenience sampling methods. Data were collected through questionnaires, interview guide, observation guide and Focus Group Discussions (FGDs) and were analysed qualitatively using thematic data analysis technique and quantitatively employing descriptive data analysis method. As such, this study established issues that girls, who do weekly boarding at Chadiza Day Secondary Schools, were involved in; and how these issues impeded their education. The findings served as an eye-opener for the School administration, teachers and parents to provide services that would help to provide quality education and reduce existing issues that impede the education of girls. The results of the study were discussed in reference to thematic areas of the findings; related literature on girls’ issues in weekly boarding and the authors drew attention to how these issues impeded their education. The study concludes that weekly boarding in day secondary schools is a good initiative but should be provided under what may be called ‘supervised weekly boarding’ in order to avoid girls’ issues that may affect their education and life at large.
