Effect of nano-cellulose on the improvement of the properties of paper newspaper produced from chemi-mechanical pulping
Authors: Kasmani Jafar Ebrahimpour , Samariha Ahmad
Published: April 2023

The effect of nanofibrillated cellulose (NFC) was investigated relative to the strength of chemi-mechanical pulp (CMP) and paper. The NFC was added at five levels: 0%, 2%, 4%, 6%, and 8%. Handsheets with a basis weight of 60 g/m2 were prepared, and the physical properties (air resistance and surface roughness), the mechanical properties (tensile strength, burst strength, and tear strength), and the optical properties (brightness, opacity, and yellowness) were measured according to TAPPI standards. By increasing the NFC content, the tensile strength, burst strength, air resistance, brightness, and whiteness increased by 10.9%, 12.5%, 23.6%, 0.6%, 3.5%, and 6.8%, respectively, compared to the control (0% NFC) samples. By increasing the NFC content, the tear strength, roughness, and opacity decreased by 10.4%, 11.1%, and 0.6% compared to the control samples.
Ternary flame retardant system based on the in-situ polymerization of ammonium polyphosphate-diatomite-aluminium trihydroxide
Authors: Li Jing , Zhao Huifang , Sha Lizheng , Zhang Hui , Ding Mingqi , Liao Changlv
Published: April 2023

A three-component flame-retardant system was prepared based on in situ polymerization of ammonium polyphosphate (APP), diatomite (DE), and aluminium trihydroxide (ATH) to improve the flame retardance and smoke suppression properties of fibrous materials. Compared to the two-component system of APP-DE, the addition of APP-10% DE-4% ATH dosed at a filler load of 20% of the fibrous material reached a limited oxygen index of 27.5%, which was approximately 9.1% higher than the two-component system. The lower mass loss rate and higher residual mass at high temperatures resulted in excellent flame retardance. The synergistic effect on alleviating combustion and reducing heat release was shown by the 16.6%, 22.1%, and 12.5% decreases in the peak heat release rate, total heat release, and average effective heat combustion, respectively. Superior fire resistance was demonstrated by a higher fire performance index and a lower mass loss. A smoke suppression effect was shown by the peak smoke release rate and the total smoke release results that were 28.7% and 15.8% lower than the two-component system, respectively. Based on the porous structure of DE and generated aluminum oxide (Al2O3), the outstanding adsorption effect and flame-retardant effect was also demonstrated by the production rate of carbon monoxide (CO) and carbon dioxide (CO2).

Tracer indicators in patients with acute surgical abdomen
Authors: Céspedes Rodríguez Héctor Alejandro
Published: April 2023

Introduction: The tracer indicators are elements to be taken into account by the surgical services to know the morbidity and mortality in the non-traumatic acute abdomen. Objective: To describe the characteristics of tracer diseases in the non-traumatic acute abdomen in the General Surgery service of the Manuel Ascunce Domenech University Hospital in Camagüey. Methodological design: A cross-sectional longitudinal descriptive observational study was carried out in 657 patients. The data came from the medical records and were processed using descriptive statistics, relating some variables in a non-inferential way. Results: 60.6% of the patients were men. 30.7% were between 40 and 59 years old. There were 334 patients with symptom evolution time between 24-47 hours. 42.5% presented acute appendicitis. There were 29.2% complications, 66.1% of them were infectious. Mortality was 10.2%. 37.3% of the deceased presented pulmonary thromboembolism, 50.7% presented intestinal occlusion. The reoperation and readmission rates were 5.3% and 7.6%, respectively. Conclusions: The study of tracer diseases shows that: Almost a tenth of the patients died, being pulmonary thromboembolism the cause of the deaths. The time of evolution greater than 24 hours, infectious complications, ages over 40 years and intestinal occlusion as a cause of acute abdomen seemed to influence the mortality of the sample studied. Evisceration and infection of the operative site were the causes of admissions and reoperations.
Evaluation of fecal incontinence symptoms in adult women and impact on their quality of life
Authors: Massahud Matheus
Published: April 2023

Fecal incontinence is an important complaint with great impact in patient’s quality of life. Its cause is multifactorial, its diagnosis greatly underestimated, and its prevalence increases with age. Fecal incontinence is defined as any involuntary loss of feces – liquid or solid – or gas in patients older than 4years of age. Fecal incontinence can be present in up to 15% of patients older than 70years. Only 10 to 30% of symptomatic patients seek medical attention. Up to 40% of symptomatic women have major fecal incontinence with even greater impact on quality of life. Health care professionals’ awareness and patient information are paramount for diagnosis and treatment of the issue.
Policing and Overuse of the Juvenile Justice System
Authors: Jindal Monique
Published: April 2023

National attention toward recent highly publicized police killings and the coronavirus disease 2019 pandemic, which has disproportionately impacted communities of color, highlight the continued systematic oppression of racial and ethnic minorities in the United States. Furthermore, burgeoning evidence demonstrates that police contact is associated with adverse health outcomes for Black and Latinx youth beyond the loss of life. This article seeks to describe the historical and contemporary context of youth’s experiences with the police and present the state of the science linking police contact to poor health. The evidence suggests that police contact is a critical determinant of health for racial and ethnic minority children and that pediatric clinicians, researchers, and policymakers have a role in mitigating the detrimental impact of policing on child health.
Ígéretek és tények – a pedagógusbérekről és azok hatásáról

Az írás azt vizsgálja meg, hogy a hazai pedagógusbérek és azok állami támogatása
hogyan alakult az elmúlt évtizedben, nemzetközi összehasonlításra is kitekintve.
Ezt követően a tanulmány elemzi a bérek hatását a pedagóguspálya, illetve egyes
tanár szakok iránti keresletre, a jelentkezők számára és a bejutási
pontszámokra. Végül górcső alá veszi a pedagógusbér-emelés forrásaként tervezett
EU-támogatási projekt jellemzőit, a forrás nagyságát s az annak hatására
létrehozható béremelést, továbbá egy ilyen béremelés sajátosságait.
Összegzésként megállapítja az írás, hogy a pedagógusok érdekérvényesítő
képessége gyenge, s ennek nyomán a pedagógusbérszint és a pedagógusbér-rendezés
jól halasztható, a rövid távú politikai szemlélet miatt messze nem élvez kiemelt
kormányzati prioritást, ugyanakkor hosszú távon a pedagógusok presztízse,
megbecsültsége meghatározó az oktatás minőségére.

Providing Rewards as an Effort to Grow Self-Confidence in Madrasah Ibtidaiyah Students
Authors: Latifah Alia , Ichsan Ichsan
Published: April 2023

In the learning process there needs to be motivation so that students can improve their learning outcomes. By participating in learning activities, students are expected to be able to develop themselves socially, emotionally, intellectually, linguistically, morally and personally in the positive direction that everyone wants. This is inversely proportional to the current reality that there are still students who are shy or don't dare to express their thoughts in public.thus making students less confident when answering questions from the teacher so that rewards come out as reinforcement. This study aims to reveal the giving of rewards to students' self-confidence. The research method used is descriptive qualitative with data collection techniques in the form of interviews. The subject of this research is a class III teacher at MI Al-Mutaqin. The results of the study revealed that the application of rewards to students at the elementary school/Madarsah Ibtidaiyah level was given by the teacher in learning including giving verbal rewards. The reward given has the impact of growing students self-confidence in learning.Keywords: Confidence, Madrasah Ibtidaiyah, Reward
„Immediacy of Experience Principle” z plemienia Pirahã jako możliwa powszechna podstawa epistemologii
Authors: Petryszak Karol
Published: April 2023

Szeroko opisane przez Daniela Everetta plemię Pirahã pozwala na odniesienie kierującej zachowaniem jego członków zasady bezpośredniości doświadczenia do szerszego kontekstu epistemologicznego. W artykule poza przedstawieniem samej zasady bezpośredniości doświadczenia uzasadniono, dlaczego stanowi ona ostatecznie podstawę każdej epistemologii – choć w różnym stopniu wpływa na późniejsze rozwiązania epistemologiczne. Sformułowano również postulat opracowania „poziomów abstrakcji”, co pozwoliłoby na prowadzenie dalszych badań pod kątem choćby rzeczywistego istnienia desygnatów danych tzw. pojęć abstrakcyjnych.

Solid oxide fuel cells (SOFCs) have been attracting considerable attention as ecologically friendly and highly efficient power sources with a variety of applications. Modern directions in the SOFCs technology are related to lowering the SOFC operating temperature that require both advanced materials design and development of versatile technologies to fabricate SOFC with thin-film electrolyte membrane to decrease ohmic losses at decreased temperatures. Electrophoretic deposition (EDP) is one of the most technologically flexible and cost-effective methods for the thin film formation currently available. This review highlights challenges and approaches presented in literature to the formation dense thin films based on oxygen-conducting and proton conducting electrolytes, as well as multilayer and composite electrolyte membranes.
Directed Search Based on Improved Whale Optimization Algorithm for Test Case Prioritization
Authors: Yang Bin , Li Huilai , Xing Ying , Zeng Fuping , Qian Chengdong , Shen Youzhi , Wang Jiongbo
Published: April 2023

With the advent of the information age, the iterative speed of software update is gradually accelerating which makes software development severely limited by software testing. Test case prioritization is an effective way to accelerate software testing progress. With the introduction of heuristic algorithm to this task, the processing efficiency of test cases has been greatly improved. However, to overcome the shortcomings of slow convergence speed and easy fall into local optimum, the improved whale optimization algorithm is proposed for test case prioritization. Firstly, a model called n-dimensional directed search space is established for the swarm intelligence algorithm. Secondly, the enhanced whale optimization algorithm is applied to test case prioritization while the backtracking behavior is conducted for individuals when hitting the wall. In addition, a separate storage space for Pareto second optimization is also designed to filter the optimal solutions of the multi-objective tasks. Finally, both single-objective and multi-objective optimization experiments are carried out for open source projects and real-world projects, respectively. The results show that the improved whale optimization algorithm using n-dimensional directed search space is more conducive to the decisions of test case prioritization with fast convergence speed.
A new belief entropy and its application in software risk analysis
Authors: Chen Xingyuan , Deng Yong
Published: April 2023

The measurement of uncertainty has been an important topic of research. In Dempster’s framework, Deng entropy serves as a reliable tool for such measurements. However, it fails to consider more comprehensive information, resulting in the loss of critical data. An improved belief entropy is proposed in this paper, which preserves all the merits of Deng entropy. When there is only a single element, it can be degraded to Shannon entropy. When dealing with multiple elements, the partitioning method employed for mass functions makes it more responsive and efficient than alternative measures of uncertainty. Some numerical examples are given to further illustrate the effectiveness and applicability of the proposed entropy measure. Additionally, a case study is conducted on software risk analysis, demonstrating the practical value and relevance of the proposed method in real-world scenarios.
Avaliação do desenvolvimento tecnológico em saúde a partir da ocorrência das epidemias de zika e chikungunya no Brasil
Authors: Fernandes Maria da Conceição Rodrigues , Monte Washington Sales do , Bezerra Francisco Silvestre Brilhante
Published: April 2023

Buscando compreender como as epidemias de zika e chikungunya incitaram o desenvolvimento tecnológico, este estudo realizou levantamento de dados epidemiológicos e prospecção tecnológica, utilizando dados do Instituto Nacional da Propriedade Industrial (INPI) e do Orbit Intelligence. Ainda, analisou produtos desenvolvidos e em desenvolvimento a nível mundial e aqueles registrados no Brasil por meio da Agência Nacional de Vigilância Sanitária (Anvisa). No ano de 2016, observou-se o maior número de casos totais para ambas as doenças. A prospecção tecnológica nacional revelou que há interesse global em desenvolver tecnologias para essas doenças e depositar suas patentes no Brasil, tendo as empresas como principais depositantes. Por sua vez, a prospecção tecnológica global mostrou que o ano de 2016 configura-se como importante marco na evolução do número de patentes para zika e chikungunya, sugerindo que as epidemias brasileiras estimularam o mundo no desenvolvimento de novos insumos para a saúde. Os Estados Unidos e a China são as principais jurisdições, tendo as universidades como maiores depositantes. A análise de produtos a nível global revelou que apenas dois chegaram ao mercado para zika e um para chikungunya, e as vacinas estão na categoria principal. A busca na Anvisa revelou que há mais produtos registrados para zika do que em comparação à chikungunya. Os principais fabricantes legais são empresas brasileiras, com pedidos de registro realizados principalmente pelas empresas DiaSorin S.p.A., ECO Diagnóstica Ltda. e Chembio Diagnostics Brazil Ltda. Apesar do visível estímulo à pesquisa, desenvolvimento e patenteamento gerado pelas epidemias de zika e chikungunya no Brasil, isso não garantiu a chegada de novos produtos ao mercado nem acesso da população a eles.

Published: April 2023

O declínio global das coberturas vacinais levou a Organização Mundial da Saúde (OMS), em 2019, a definir a hesitação vacinal como uma das dez maiores ameaças mundiais à saúde pública. No Brasil, a queda da cobertura vacinal teve início em 2012, acentuando-se a partir de 2016, e sendo agravada pela pandemia de COVID-19. O alerta da baixa cobertura vacinal vem acompanhado pela reintrodução de doenças imunopreveníveis como o sarampo. O retorno de doenças até então eliminadas, como a poliomielite, pode agravar a crise sanitária ainda em curso. Mesmo sendo reconhecido como um dos mais efetivos programas de imunizações do mundo e dos esforços permanentes, o Programa Nacional de Imunizações enfrenta um cenário extremamente adverso no que tange às coberturas vacinais. Este artigo descreve o Projeto pela Reconquista das Altas Coberturas Vacinais (PRCV) e a estratégia de trabalhar na ponta do sistema, executada nos territórios, que vem sendo implementada desde 2021 e já começa a apresentar resultados promissores. O PRCV foi organizado em três eixos temáticos com atuação compartilhada e ações específicas, a saber: vacinação; sistemas de informação; comunicação e educação. Os resultados já alcançados permitem afirmar que é possível conseguir a reversão das baixas coberturas vacinais, a partir da articulação de ações estruturais e interinstitucionais, com o fortalecimento das políticas públicas e desenvolvimento de medidas de curto, médio e longo prazos. Os fatores mais potentes do PRCV são sua abordagem junto aos profissionais da ponta, o pacto social pela vacinação, e a estruturação de redes locais de apoio às imunizações.
Sobrevivendo no inferno: a escrita da história na eco-crise global
Authors: Marques Leonardo
Published: April 2023

RESUMO A atual crise energética e as questões de sustentabilidade ligadas a ela podem ser compreendidas melhor quando enquadradas no colapso ambiental mais amplo do qual são parte. A eco-crise mundial atualmente em curso ocupa um lugar incontornável em debates na esfera pública e na agenda política de diferentes governos ao redor do mundo. Historiadores têm participado de diferentes formas dessas discussões, que com frequência trazem embutidos modelos de análise histórica simplistas, quando não a-históricos. No entanto, historiadores com frequência também operam de modo irrefletido por meio de categorias produzidas pela história do capital, que tendem a naturalizar as formas de ver e experimentar o mundo, e que estão na base do colapso ecológico de nossa época. O presente artigo apresenta reflexões em torno desses problemas e explora possibilidades de análise histórica no contexto do colapso ambiental.
“A população precisa conhecer os perigos que corre!”: consumo cinematográfico e retóricas do medo no Rio de Janeiro da Belle Époque
Authors: Lapera Pedro Vinicius Asterito
Published: April 2023

RESUMO Este artigo aborda a série jornalística Cinemas-arapucas, veiculada pelo jornal A Noite entre os dias 8 e 16 de agosto de 1912, que teve como foco a denúncia contra alguns cinemas das áreas centrais do Rio de Janeiro por conta do não-cumprimento de regras relativas à segurança do público. Pretendemos verificar como a série jornalística inseriu-se na disseminação de uma retórica do medo em relação ao consumo cinematográfico - e, por extensão, com quais outros medos dialogava e que mecanismos de poder acionava a partir disso. Como questão central, nossa proposta é analisar a série Cinemas-arapucas para verificar algumas relações entre imprensa, autoridades, donos de cinematógrafos e público de cinema no Rio de Janeiro das primeiras décadas do século XX. Para tanto, adotamos como metodologia em nossa pesquisa o paradigma indiciário, tal como proposto por Carlo Ginzburg.
“The Population Needs to Know the Dangers They Face!”: Cinematic Consumption and Rhetoric of Fear in Belle Époque Rio de Janeiro
Authors: Lapera Pedro Vinicius Asterito
Published: April 2023

ABSTRACT This article addresses the journalistic series Cinemas-arapucas (Trap-cinemas), published by the newspaper A Noite between August 8 and 16, 1912, which denounced some movie theaters in the central areas of Rio de Janeiro because of noncompliance with rules related to public safety. We intend to verify how the journalistic series was inserted in the dissemination of a rhetoric of fear regarding cinematographic consumption - and, by extension, with which other fears it engaged and what mechanisms of power it triggered from this. As a central question, our proposal is to analyze the Cinemas-arapucas series to verify some relations among the press, authorities, cinematographers, and cinema audiences in Rio de Janeiro in the first decades of the 20th century. To do so, we used the evidential paradigm methodology, as proposed by Carlo Ginzburg.
Jogos de gênero, maternalismo e política: “uma mulher operária” na Câmara de Vereadores de Porto Alegre (1948-1951)
Authors: Nunes Guilherme Machado
Published: April 2023

RESUMO Após a queda do Estado Novo, o Brasil passou por um processo de redemocratização e de reestabelecimento de suas casas legislativas. No final de 1947, diversas capitais do país realizaram eleições para suas Câmaras Municipais, em um pleito que levaria algumas mulheres a exercerem o cargo de vereadoras pela primeira vez. Em Porto Alegre, a operária comunista Julieta Battistioli acabou a disputa como primeira suplente do colega Elóy Martins, mas ao longo da legislatura assumiu a tribuna diversas vezes, protagonizando intensos debates com os demais vereadores. O objetivo deste artigo é analisar alguns dos espaços por onde Julieta circulou e, principalmente, alguns desses embates, identificando estratégias e ressignificações adotadas por ela, de forma a se legitimar em um ambiente até então exclusivamente masculino.
Rituais públicos com intervenção de Juan de Albuquerque, primeiro bispo de Goa residente na Ásia. Linguagens de transferência ou de acomodação?
Authors: Paiva José Pedro
Published: April 2023

RESUMO Uma das estratégias adotadas pelo franciscano Juan de Albuquerque, primeiro bispo da Índia a residir na Ásia, ao desembarcar em Goa em 1538, foi a realização e a intervenção em rituais públicos, a exemplo da sagração da catedral, dos batismos de importantes personagens locais, das bençãos de armadas portuguesas que partiam para a guerra, da entronização de governadores ou vice-reis e das práticas de exercício de justiça eclesiástica. Este artigo propõe o mapeamento e a reconstituição desses eventos a partir da cronística e de diversos relatos coevos de quem participou nesses rituais. Defendemos que os modelos que conformavam estas cerimônias tinham um padrão que replicava na Ásia os rituais europeus. Neste estudo avaliar-se-á de que modo se conformaram com o mundo que, para os portugueses ali instalados, era novo e diferente: Goa nos anos 40-50 do século XVI.

Effects of enabling characteristics of budgetary control on the psychological capital of managers with budgetary responsibility

Published: April 2023

ABSTRACT This study investigates the influence of enabling characteristics of budgetary control on the psychological capital of managers with budgetary responsibility. Within the budgetary context, the studies that analyze the effects of enabling characteristics of budgetary control on individuals’ mental states at work are still in their infancy and that is a theoretical gap explored in this research. The research evaluates the interactive and multidimensional effects of enabling budgetary control on psychological capital. It advances the literature by indicating which characteristics exert the greatest influence on psychological capital and its dimensions. The results provide evidence of the enabling effects of enabling budgetary control on the psychological capacities of managers with budgetary responsibility, being positively reflected in their beliefs of self-efficacy, hope, optimism, and resilience for achieving their objectives and the desired organizational results, which tends to have an impact on the individuals’ as well as the organization’s performance. A survey was conducted in a publicly-traded company operating in Brazil, using a quantitative approach to the data (structural equation modeling). The sample analyzed included 85 middle-level managers from different areas of the organization. The possibility of adjusting budgetary reports and accessing detailed information on budgetary deviations (repair capacity), as well as of incurring expenses unforeseen in the budget and adjusting the original budgetary assumptions (budgetary flexibility), positively contributes to promoting managers’ psychological capital. However, this does not occur with internal transparency and global transparency. Within the context studied, the benefit of repair capacity primarily takes the form of self-efficacy, resilience, and hope, while the benefit of flexibility primarily occurs in terms of optimism and hope. These results contribute to organizations designing their management control systems so as to develop the psychological capital of their collaborators and thus obtain the benefits expected from that development.

SCIENTIFIC LITERACY IN HUMAN SCIENCES: TOWARDS A DIALOGUE
Authors: Ferreira Eduardo Carvalho , Moraes Jerusa Vilhena de
Published: April 2023

Abstract The present study aims to discuss and problematize how close is the relationship between the notion of scientific literacy and school teaching of human sciences by presenting the results of the analysis of 32 articles, focusing on their main contributions, principles, challenges and suggestions that may potentially foster the dialogue between scientific literacy and human sciences. The construction of the analysis was based on a heuristic methodology whose results gave visibility to four general aspects: scientific literacy as a way to qualify human sciences teaching, the strengthening of a vision about school education based on scientific values, the valorization of practices as a place of formative experience and the viability of scientific literacy to be thought of as a social practice.
Teaching work in Medicine at a federal university in the Southern region Brazil
Authors: Matos Izabella Barison , Boneti Lindomar Wessler , Ferla Alcindo Antônio
Published: April 2023

Abstract Brazilian public policies approach the international paradigm of interaction between training and health systems advocating for a general medical training, linked to the population’s epidemiological profile, and reverberating on teaching work. This work sought to analyze perceptions about teaching and professional perspectives of professors of the medicine course at a federal university. This is a descriptive study with a qualitative approach, with a questionnaire, documentary and bibliographic research, and analysis from the perspective of hermeneutics-dialectic. From the results, four categories of analysis were constructed that describe the teaching work from the perspective of its actors: training markers for teaching (the repertoire of knowledge of teaching practice is experiential); imaginaries attributed to teaching (conflict with the ideal image previously conceived); confrontations in the teaching routine (the generalist training recommended has less social recognition); teaching and its horizon (search for greater qualification). The investments - personal and institutional - have not been sufficient in face of aspects that generate dissatisfaction and the perception of unpreparedness of teachers in the daily routine of medical training, denouncing a certain discomfort among professors. It can be said that the teaching work is fundamental for the change in training, and that the perception of the actors of a concrete experience points out deficits in pedagogical training and in permanent education.
BLACK MALES IN NON-STEM AND STEM OCCUPATIONS
Authors: López Omar S.
Published: April 2023

While many labor market studies have examined wage inequality by race, gender, and class, the
research has seldom directly considered labor market outcomes of STEM college graduates within the context of non-STEM and STEM occupations. The current study investigates the determinants of wages among Black males in STEM and non-STEM occupations compared to their White male peers. Through this investigation, it explores the feasibility of broadening Black males' participation in STEM
occupations but also how they might earn higher wages and thereby close the wage gap with White
male peers. The Public Use Microdata Sample (PUMS) files for the 2018 American Community Survey (ACS) were the primary data source for the current study. Following the convention in labor economics, the author used Mincer's single-equation model to explain variations in earnings as a function
of select wage determinants derived from the data. Three main insights emerged from the current
study. The findings suggested that opportunities do exist for employers to hire qualified Black males
seeking gainful employment in STEM occupations. The findings also indicated that within the Black male group, working in a STEM occupation with a college degree in a STEM field was the best route to attain maximum wages. The third insight from the current study cannot be avoided: the noticeable gaps in wages between White and Black males. Implications of the findings for employers seeking to diversify their STEM workforce and for Black males considering employment or employed in a STEM occupation are discussed.

Published: April 2023

Given the non-uniform melting of the end face of a joint and the local non-fusion of the joint in large-diameter hollow stud welding, to research the law of arc motion, the joint-forming quality, weld microstructure and mechanical properties in the process of hollow stud welding propelled by a longitudinal magnetic field were investigated in this study. The results reveal that under the influence of a longitudinal magnetic field, the arc on the end of a stud is affected by the Lorentz force and spirals downward. In the welding process, with an increase in magnetic field intensity, the arc uniformly burns the stud end face, preventing local non-fusion and resulting in a well-shaped joint. Under the action of magnetic field stirring, eutectoid ferrite is broken, the content of eutectoid ferrite and bainite is diminished, the nucleation barrier is reduced and the grain is refined. Under the action of a longitudinal magnetic field, the shear strength of the hollow stud welded joint rises to 312 MPa, surpassing the strength of a joint welded without a magnetic field.
The Effects of Surprising Events on Promoting Social Change in Unwinnable Persuasive Games

Published: April 2023

Surprising events can be beneficial for unwinnable persuasive games, especially since they can evoke players to reflect on their failure to win the game. Despite its presence in some titles, the usage of surprising events still lacks empirical support. This study aims to gain insight into it by comparing the effects of revealing the game’s context from the beginning to delaying it until the game ends. In addition, we also examine the interaction effects with playing duration since it is possible that longer playtime will lead to smaller effects for a game with surprising events, whereas longer playtime will result in greater effects for a game without surprising events. To do so, we conducted a 2 x 2 factorial between-subject experiment with an additional no-treatment control group. The results suggest that delaying the revelation to create a surprising event can promote the same level of donation from players, regardless of their playing time. On the other hand, longer playtime is important if players know the context from the beginning. Additional results about the effect of playing duration on donation and willingness to help were also discussed in this paper.

Schistosoma mansoni cercariae shedding v1
Authors: K Buddenborg Sarah
Published: April 2023

Schistosoma mansoni cercariae can be obtained from infected Biomphalaria glabrata snails. Although infected snails will release (shed) cercariae constantly at low numbers, it is possible to trigger the release of larger quantities by keeping the snails in the dark for a few days before shedding. Material obtained from these procedures can be mechanically transformed into schistosomula for further experimentation.

Authors: Froes santos Rosilene Aparecida , Fialho de Sousa Marcio Jean , Froes Santos Rosana
Published: April 2023

As produções literárias possibilitam a elucidação de temáticas que carecem de atenção, dentre esses temas destaca-se a violência contra a mulher. Nesse sentido, o objetivo deste estudo é refletir acerca das formas de violência contra a mulher presentes no conto “A caolha” (2001). O conto será analisado sob a luz da Lei Nº 11.340 / 2006, documento esse que institui estratégias para coibir a violência contra a mulher no contexto nacional. A elucidação de formas de violência no contexto literário, no conto “A caolha” (2001), propicia ao leitor refletir acerca da violência no território literal.
Vulnerability to Disinformation in Relation to Political Affiliation in North Macedonia

Published: April 2023

This study aims to analyze the relationship between political affiliation and vulnerability to disinformation in North Macedonia through the role of psychological and social constraints in shaping how individuals respond to and process information. Research has shown that politically affiliated individuals may be particularly vulnerable to disinformation in part due to confirmation bias or the tendency to accept and seek out information that is consistent with one’s preexisting beliefs and ignore or refute information that is not. Using the quantitative method and cross-matched data from the empirical research, the study has shown that political affiliation affects the way individuals perceive disinformation. Correspondingly, disinformation with a negative connotation from one’s affiliated political party is perceived by a lower percentage as accurate, contrary to disinformation with a negative connotation from the opposing political party, which is perceived by a higher percentage as accurate. The study also found that politically affiliated individuals are more prone to disinformation than those who are not politically affiliated. The results suggest that political affiliation plays a significant role in an individual’s vulnerability to disinformation.
Experimental Geometry, Pythagorean Theorem and Montessori
Authors: Silva Circe Mary Silva
Published: April 2023

Background: Some 19th and 20th-century geometry textbooks show methodological innovations in relation to the traditional books that followed Euclid's logical-deductive proposal. Objective: To analyse in the book Psico Geometria: el estúdio de la geometria basado en la psicologia infantil by Maria Montessori (1934) as the didactic approach of the Pythagorean theorem, proposed by her, fits into an experimental geometry perspective. Design: Using documentary analysis, we analysed the books of the following authors: Hoüel (1867), Méray (1874), Laisant (1898, 1906), Calkins (1861), Bert (1886), Prestes (1895), Lyra da Silva (1923), Wentworth and Hill (1901) and Montessori (1916, 1934) to understand the approach to teaching geometry.Environment and participants:The research sources collected in the National Library of France (BNF) and in the Universidade Federal de Santa Catarina (UFSC) Digital Repository refer to the geographic environment of authors from four countries Data collection and analysis: The selected and analysed documents can be found at BNF – Gallica in a digitized version, as well as at the UFSC Digital Repository. Based on the documentary analysis of these books, we found that the methodological proposals seek to escape from a deductive presentation of elementary geometry and include in their texts experiences for the introduction of concepts and visual demonstrations of elementary geometry. Results: The authors of the analysed works, from different countries, criticized the elementary teaching of geometry, especially the authors of textbooks, for the fact that they approach deductive geometry in the initial classes, favouring a deductive presentation of mathematics. Montessori's book shows an experimental geometry proposal for the Pythagorean theorem. Conclusion: We found that Montessori's proposal, besides presenting characteristics of an experimental geometry, also inserts some deductive reasoning.
Contextualisation of Geometry Tasks in High School Mathematics Textbooks
Authors: Litoldo Beatriz Fernanda , Amaral Rúbia Barcelos , Mazzi Lucas Carato
Published: April 2023

Background: Geometry is often seen as an area of mathematics that is present in everyone’s daily life. Looking around, we see it in the shapes of objects, in nature, etc. Therefore, it would be natural to expect that its approach in textbooks, for example, would bring different contexts in which it would be present. Objective: To discuss how contexts are introduced in geometry tasks in a collection of mathematics textbooks. Design: We use a qualitative approach of the documentary type as a methodology. Environment and participants: A collection of high school mathematics textbooks approved by the National Textbook and Didactic Material Program – 2018 was selected. Data collection and analysis: Data were produced, organised, and analysed using horizontal and vertical analysis methods in each collection volume, according to the different references of contexts. Results: They concern the different references of contexts involved in the tasks. From the 1,335 tasks analysed, 1,108 were contextualised in purely mathematical situations, while the rest, 227, were in contexts of reality. In this, there are 215 referring to reasonable semi-realities, and, on the other hand, the real context contemplates only three. Finally, nine concern tasks in unreasonable semi-real contexts. Conclusions: The restriction of the different context references that students can experience from this collection is discussed. The contexts presented do not include a broad spectrum based on a diversity of experiences among the different references of contexts.
