The effects of national culture on environmental disclosure: A cross-country analysis
Authors: Pinheiro Alan Bandeira , Oliveira Marcelle Colares , Lozano M. Belén
Published: March 2023

ABSTRACT This study aims to answer the following research question: How does national culture affect environmental disclosure in liberal economies? Several previous studies have shown that formal institutions, such as the characteristics of the government, the country's financial system, have an influence on environmental disclosure. However, there is still a gap in the literature on how informal institutions (the country's culture) can influence the behavior of companies. The results of this study provide a solid understanding of environmental disclosure in liberal economies. In these economies, it is common for companies to be more interested in disclosing financial and governance information. Thus, analyzing environmental disclosure in these companies presents an additional gain for the literature. Managers can use our findings to understand how the country's culture can influence their business. The adoption of the Global Reporting Initiative (GRI) disclosure guidelines and the presence of a sustainability committee in the company can help companies achieve better environmental performance. We examined the level of environmental disclosure for a sample of 1,037 companies based in Australia, Canada, Ireland, New Zealand, United Kingdom, and United States of America (USA) for the period 2015-2018. To measure national culture, we used the proposed cultural dimensions by Hofstede (1983): distance to power, individualism, masculinity, aversion to uncertainty, long-term orientation, and indulgence. Our evidence shows that power distance, individualism, and masculinity have a positive effect on environmental disclosure. The results show that in cultures with less aversion to uncertainty, companies disclose more environmental information. Our findings also show us that companies that carry out an environmental disclosure following GRI guidelines disclose more sustainability information. The results show that sectors such as energy, materials, and utilities have greater environmental disclosure.
Dividend-yield variation as an asset selection criterion in momentum strategies of Brazilian real estate investment trusts
Authors: Greenhalgh Luis Henrique , Campani Carlos Heitor
Published: March 2023

ABSTRACT We aimed at showing the usage of the dividend-yield (DY) variation as a criterion for selecting Brazilian real estate investment trusts (BR-REITs) in momentum strategies. The identification of momentum in BR-REITs with this selection criterion is, to the best of our knowledge, new and gives rise to different strategies that seize abnormal returns. This study allows a new understanding of the dynamics between prices and dividend payments, which compose BR-REITs returns. It is of major importance, considering the relevance of the DY ratio for the asset class. The studied strategies delivered results above the industry’s index with expressive magnitude, are of simple elaboration, and can be applied by any individual or institutional investor. Portfolios’ performances were measured by Sharpe ratio (SR), alpha of the Fama and French three-factor model, and excess returns obtained in relation to the BR-REITs’ index. Statistical tests were applied to verify the significance of the results. This study showed that strategies around the momentum effect that buy (sell) BR-REITs with greater (smaller) DY variations in previous months tended to have superior performance to the industry’s index.

Published: March 2023

Abstract Jaboticaba peels are an important source of health-benefit and antimicrobial compounds. The present work aims to evaluate concentration of polyphenolics and the mode of action of aqueous extract from jaboticaba peels against Staphylococcus aureus and Escherichia coli. Jaboticaba peel extract showed minimum inhibitory concentration and minimum bactericidal concentration against S. aureus of 5.1 g L-1 and 10.1 g L-1, respectively; meanwhile, against E. coli the parameters were 2.0 g L-1 and 3.4 g L-1. Kinetics of viable cell counts indicated a bacteriolytic action against both bacteria and Scanning Electron Microscopy (SEM) showed that jaboticaba peel extract causes subtle morphological changes in bacterial cells. Concentration of total polyphenols in the extract was 1535.04±36.05 mg of gallic acid equivalent (GAE) mL-1, monomeric anthocyanins was 14.52 ± 0.98 mg of cyanidin 3-glucoside mL-1, condensed tannins was 0.49 ± 0.05 mg of epicatechin equivalent mL-1 and phenolic acids was 80.04 ± 4.11 mg of caffeic acid equivalent (CAE) mL-1, which have demonstrated well-documented antibacterial activity. In conclusion, jaboticaba peel aqueous extract may be an interesting natural preservative to control Gram-positive and Gram-negative bacteria growth when interacting with the bacteria cell wall.

Published: March 2023

ABSTRACT Purpose To compare the vowel emission and number counting tasks in perceptual-auditory differentiation among children with and without laryngeal lesions. Methods Observational, analytical, and cross-sectional methods were used. Medical records of 44 children were selected from a database of an otorhinolaryngology service at a University Hospital and they were divided into groups: without laryngeal lesion (WOLL), and with laryngeal lesion (WLL), with 33 and 11 children. For the auditory-perceptual evaluation, the vocal samples were separated according to the type of task. They were analyzed separately by a judge who analyzed the general degree of vocal deviation and assessed whether the child would pass or fail in the face of a screening situation. Results There was a difference between the WOLL and WLL groups in terms of the overall degree of vocal deviation for the task of number counting, with a predominance of mild deviations in WOLL and moderate in WLL. In the screening, there was a difference between the groups during the number counting task, with more failures in the WLL. The groups were similar in the sustained vowel task, both in terms of the overall degree of vocal deviation and the vocal screening. Most children in the WLL failed in both tasks during vocal screening compared to the children in the WOLL who, in general, failed in only one task. Conclusion The task of number counting contributes to the auditory differentiation in children with and without laryngeal lesion, by identifying deviations of greater intensity in children with laryngeal lesion.

Covid-19 y Educación Superior. Evaluación de la continuidad didáctica en Cuba
Authors: Masegosa Antonio Nadal
Published: March 2023

Resumen La evaluación de lo acontecido con la repentina aparición del virus Covid-19 con respecto a la Educación Superior a lo largo y ancho del planeta enfrenta un alto número de dificultades, con todo tipo de matices, y la necesidad de atender a una realidad multifactorial. El análisis de lo acontecido en cualquier lugar del mundo, cuando menos, necesita de actores y actrices principales, al menos, a modo de fuente primaria de conocimiento. Conocer de forma general qué aconteció en Cuba fue el objetivo inicial de la presente investigación, atendiendo en primer lugar a lo aportado por las informaciones oficiales, escasas, y probablemente poco actualizadas. Pese a ello, fue posible establecer una serie de consideraciones que muestran las vicisitudes de la continuidad de la didáctica en la Enseñanza Superior en Cuba.

Published: March 2023

RESUMO Este trabalho teve como objetivo sistematizar a produção acadêmica referente à temática Educação em Saúde desenvolvida em programas de pós-graduação no Brasil. Por questões operacionais, optou-se pelo recorte quadrienal 2015-2019, mesmo período em que os programas de pós são avaliados pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior. O processo de sistematização realizou-se entre os meses de agosto e dezembro de 2020, utilizando-se da técnica de revisão integrativa com vistas à inclusão e à exclusão de documentos concernentes ao objetivo do estudo. Os dados indicam que a área de Educação apresentou uma performance muita baixa do ponto de vista da produção de teses e dissertações quando comparada com a área de Enfermagem por exemplo. Pôde-se indicar um distanciamento da área de Educação em relação ao tema Educação em Saúde. Conclui-se, portanto, que a temática focal deste estudo é pouco influenciada e/ou tem pouca contribuição da educação, o que pode constituir-se em um importante déficit para o desenvolvimento da temática Educação em Saúde no contexto brasileiro.
Educação infantil e pandemia da covid-19: ações dos burocratas de médio escalão na Baixada Fluminense
Authors: Costa Rejane Peres Neto , Nascimento Anelise Monteiro do , Castro e Souza Marina Pereira de
Published: March 2023

RESUMO Este artigo é um recorte de pesquisa que objetivou mapear as ações de dez municípios da Baixada Fluminense para a educação infantil no período da pandemia da covid-19, por meio do diálogo com os burocratas de médio escalão, profissionais responsáveis pela gestão municipal das creches e pré-escolas. A metodologia envolveu encontros virtuais e aplicação de questionário. O ensino remoto foi uma alternativa temporária e uma aposta para a continuidade do ano letivo com muitas contradições em relação ao trabalho pedagógico na educação infantil. Essa opção desconsiderou que muitas crianças estavam em contextos de fragilidade social, em que suas famílias estavam preocupadas com questões materiais de subsistência e com pouco acesso a artefatos e serviços tecnológicos. Os resultados apontam para a desarticulação entre os entes federados, o que dificultou as ações locais dos coordenadores de educação infantil. Assim, é importante pensar o lugar desses profissionais na burocracia estatal.
(Self)critical reflexivity, decolonial Southern social/cognitive justice and affection in languages
Authors: Takaki Nara Hiroko
Published: March 2023

ABSTRACT This article purports to outline critical educational perspectives, implicated in discursive and ideological life, as important foundations to expand decolonial Southern social/cognitive justice and affection. It also presents and discusses some findings of an ongoing research project with a similar theme in always already dilemmatic times. The research methodology prioritizes the qualitative and interpretive processes of meaning making grounded on each participant’s social place and on my own1 (as a coordinator of this project), based on the theories I have selected. Two Freirean notions are entrenched: (self)critical reflexivity as a constant process of resignifications and the ecology of knowledges. Both of them constitute contemporary ethical paradigms for research on language teacher education towards social/cognitive justice and affection. The partial results show evidence that language is used as a political and affective resource in the participants’ critical engagement in meaning making, while trying to problematize some of the issues under debate.

Published: March 2023

Entre os jovens, os universitários compõem a classe considerada mais vulnerável a desenvolver problemas de saúde mental decorrentes da pandemia de COVID-19. Assim, uma forma de entender como a pandemia afeta os universitários é por meio do constructo senso de coerência (SOC), o qual possui importante papel moderador da saúde mental, visto que ele é capaz de prever a saúde. Este estudo teve como objetivo analisar a prevalência de sintomas depressivos e os recursos de enfrentamento (senso de coerência) em estudantes universitários durante o distanciamento social, decorrente da pandemia. Trata-se de um estudo quantitativo, descritivo-exploratório e transversal. A amostra de 242 universitários caracterizou-se como não-probabilística, obtida com a aplicação da metodologia bola de neve virtual. Utilizaram-se os instrumentos: Patient Health Questionnaire-9 (PHQ-9), Questionário de Senso de Coerência (SOC-13) e questionário semiestruturado. Os participantes apresentaram escores sugestivos para a presença de sintomas depressivos (M=16; DP=7,56) e escores médios de senso de coerência (M=57; DP= 8,39). Houve associação significativa entre SOC-13 e PHQ-9, ou seja, foi observada uma associação forte inversa (R=-0,627) significativa (<0,0001), demonstrando que quanto maior o escore de sintomas depressivos, menor a pontuação de senso de coerência. Por fim, referente aos fatores sociodemográficos, houve associação significativa entre sexo (<0,0030), idade (<0,0001) e renda familiar (<0,0011) com sintomas depressivos e senso de coerência. Neste cenário, torna-se necessário o desenvolvimento de ações e intervenções nos campi universitários visando à promoção da saúde mental dos acadêmicos, auxiliando-os a lidar com o estresse e a depressão decorrentes da pandemia.
Um documento para chamar de nosso: refletindo o protagonismo estudantil a partir da experiência de uma universidade comunitária

Published: March 2023

O processo de democratização do acesso à educação superior traz à tona a temática do protagonismo estudantil na universidade. Qual o papel reservado aos acadêmicos? Eles têm espaço e possibilidade de contribuir na concepção das políticas institucionais, ou são tidos como meros clientes? Em um contexto de mercantilização da educação superior, como pensar o protagonismo político e crítico dos estudantes na universidade? Tomando como referência a experiência de construção de um documento denominado Política dos Estudantes em uma universidade comunitária localizada no sul do Brasil (Universidade de Passo Fundo), o artigo reflete sobre o protagonismo estudantil na educação superior, em especial no modelo institucional comunitário. Metodologicamente, trata-se de uma pesquisa qualitativa, cujos dados consistem na narrativa dos estudantes que participaram da construção do documento. O tratamento dos dados se deu a partir da análise de práticas discursivas e está ancorado em dois eixos de análise: a) O papel dos estudantes: do protagonismo individual ao protagonismo coletivo e b) Voltar-se para a comunidade como marca do protagonismo estudantil. O estudo revela que os estudantes desejam fazer parte da universidade para além da sala de aula, participando coletivamente da construção da instituição. Mostra, ainda, que o protagonismo estudantil se faz pela potencialização da relação com a comunidade, tendo força para levar a universidade comunitária a aproximar-se cada vez mais de sua natureza, princípios e missão públicos.
Qualification exams carried out in the professional master’s program in mathematics in the national network

Published: March 2023

Abstract This article analyzes the nature of the knowledge, especially that of a specialized nature, evoked in the solution of the questions that made up the National Qualification Exams (NQE), developed within the scope of the Professional Master’s Program in Mathematics in the National Network (PROFMAT), between the years 2012 and 2019. The focus of this program was based on the development of a solid education in Mathematics, which contemplates the needs arising from the daily lives of teachers in the school space and their broad needs for development and professional appreciation. Therefore, a qualitative study was developed in which, from the interpretative content analysis, a total of 62 questions were classified in the light of the conceptual-analytical model Mathematics Teachers’ Specialized Knowledge (MTSK), which composed the NQE applied in the first semester of the 8 years analyzed. The analysis carried out showed that: a) more than 70% of the questions focus exclusively on knowledge that appears in only one subdomain of Mathematical Knowledge (MK), the Knowledge of Topics, while only 5% of them address knowledge that appears in all subdomains of MK; b) Absence, in all questions, of knowledge associated with the Pedagogical Content Knowledge (PCK) domain. Thus, it is concluded that the evaluation developed through the NQE privileges knowledge that appears only in one of the six subdomains of knowledge that really support the teacher in his daily work with mathematics, which is opposed to the results of many relevant studies that emphasize the importance and impact of knowledge associated with the PCK domain in teaching.
SYMBOL ERROR PROBABILITY PERFORMANCE FOR GENERALIZED SELECTION COMBINING DIVERSITY RECEPTION OF M-QAM OVER RAYLEIGH FADING CHANNEL
Authors: Bamisaye Ayodeji James , Akinsanya Olusola Ayodeji , Oyeniran Olubunmi Rotimi
Published: March 2023

The performance of generalized selection combining (GSC) diversity reception symbol error probability (SEP) of square M-ary quadrature amplitude modulation (M-QAM) signals over frequency-flat Rayleigh fading channels is investigated in this work. The combining techniques considered in this paper are maximum ratio combining and selection combining (SC). We present closed-form approximate expressions for the average combined signal-to-noise ratio (SNR) and SEP in the fading channel for M-QAM signal reception in the GSC using diversity pathways that are independently, identically distributed. The simulation results validate the SEP expressions and demonstrate that, for a given number of accessible diversity paths, combining the strongest paths results in the majority of the diversity gain, and that the SNR declines as the number of combined paths increases. On the other hand, the numerical results demonstrate that, for a certain number of combined paths, increasing the number of available diversity paths can lead to a significant performance improvement.
Laboratory preparation and tensile signal response of sensor-enabled piezoelectric geobelt
Authors: Rao Y. , Ye J. , Wang H. , Wang J. , Ding G. , Ni J.
Published: March 2023

In this study, a sensor-enabled piezoelectric geobelt (SPGB) was developed and its mechanical properties and signal output mode were analysed. It is found that the output voltage signal of SPGB increases with the increase of strain rate. Furthermore, the normalised impedance of SPGB samples at different strain rates has a linear relationship with their strain rate. This study shows that the self-sensing function of SPGB can monitor its deformation signal and quantify its deformation behaviour. Thus, this function can provide an early warning and has a reference significance for further engineering applications of SPGB.
Pre-activation negativity (PrAN): A neural index of predictive strength of phonological cues
Authors: Roll Mikael , Söderström Pelle , Horne Merle , Hjortdal Anna
Published: March 2023

We propose that a recently discovered event-related potential (ERP) component—the pre-activation negativity (PrAN)—indexes the predictive strength of phonological cues, including segments, word tones, and sentence-level tones. Specifically, we argue that PrAN is a reflection of the brain’s anticipation of upcoming speech (segments, morphemes, words, and syntactic structures). Findings from a long series of neurolinguistic studies indicate that the effect can be divided into two time windows with different possible brain sources. Between 136–200 ms from stimulus onset, it indexes activity mainly in the primary and secondary auditory cortices, reflecting disinhibition of neurons sensitive to the expected acoustic signal, as indicated by the brain regions’ response to predictive certainty rather than sound salience. After ~200 ms, PrAN is related to activity in Broca’s area, possibly reflecting inhibition of irrelevant segments, morphemes, words, and syntactic structures

Published: March 2023

Justificativa e Objetivos: A doença arterial coronária (DAC) é a causa de óbito mais comum em países desenvolvidos e em desenvolvimento. Nos docentes, são observados indicadores ao desenvolvimento dessa patologia, como sedentarismo, estresse, obesidade e outros. O rastreamento desses fatores de risco é uma das formas mais eficazes para prevenção de eventos cardiovasculares. Dessa forma, objetivou-se rastrear os fatores de risco para DAC em docentes de uma faculdade privada do interior da Bahia. Métodos: Estudo de prevalência, quantitativo, descritivo, com 36 docentes, de forma aleatória. As variáveis avaliadas foram: sociodemográficas, condições de trabalho, prática de atividade física, questões gerais de saúde e teste de estresse. A estatística descritiva foi empregada para descrever as variáveis categóricas (%). O estudo foi aprovado pelo Comitê de Ética em Pesquisa da Faculdade de Tecnologia e Ciências. Resultados: A prevalência de fatores hereditários para DAC foi 87,5%. 80,6% tinham 2 ou mais vínculos empregatícios, 88,1% trabalhavam mais de 40 horas semanais e 55,6% praticavam de atividade física. Os níveis de LDL e colesterol total elevados foram de 56,3% e 58,3%, respectivamente. 72,2% dos docentes apresentaram valores elevados de Índice de Massa Corporal (IMC). A pressão arterial sistólica e diastólica elevadas foram observadas em 61,1% e 58,3%, respectivamente, havendo prevalência de 80,6% no teste de estresse na fase II. Conclusão: Os docentes dessa instituição estão suscetíveis ao desenvolvimento de DAC pela elevada prevalência dos fatores de risco. Sugere-se que sejam realizados novos estudos, com populações maiores de caráter confirmatório para elucidação dessa lacuna científica.
Headers and concussions in elite female and male football: a pilot study
Authors: Den Hollander Steve , Gouttebarge Vincent
Published: March 2023

Background: Heading is a risk factor for neurogenerative disease in football. However, the exposure to heading in elite football training is understudied.
Objectives: The primary purpose of this study was to determine the exposure to headers in elite men’s and women’s football and to describe the effects of the headers on ocular markers.
Methods: Exposure to headers was observed over three days of women’s and men’s football. The number of headers at each session was determined through video analysis, and the G-force was determined via an impact tracker. Ocular markers were assessed at the start and end of the three days, and the results were compared to determine if there were any changes. Self-reported exposure to heading was recorded after each session and compared to the number of headers observed through video analysis, to assess the validity of players’ self-reporting.
Results: Female players made an average of 11 headers per player per session. Ninety percent of the headers were below 10G, and none were above 80G. Male players made an average of three headers per player per session, with 74% of the headers recording a G-force above 10G and 3% above 80G. No meaningful changes were observed post-session in the ocular markers, and no concussions were observed. Neither cohort was able to accurately self-report exposure to headers.
Conclusion: Longitudinal studies should be designed and conducted across different levels of play in both women and men’s football as a prerequisite to develop evidence-based measures to prevent or mitigate the potential risks associated with headers and concussions in elite football.
Contextualised Approach to Mathematics in Engineering from the Perspective of Cognitive Dysfunctions
Authors: Loureiro de Lima Gabriel , Lutaif Bianchini Barbara , Gomes Eloiza
Published: March 2023

Background: The relevance of enabling beginning students of engineering courses to solve problems directly related to their future professional activities, already in the initial subjects of mathematics, implies the need to elaborate such problems, implement them and analyse their potential in terms of construction and application of mathematical knowledge in different contexts. Objectives: In this article, we analyse the cognitive dysfunctions evidenced by the students during the process of solving a problem articulating the real functions of a real variable to the study of the characteristic curve of a semiconductor diode, content linked to the analogical electronics. Design: This qualitative-nature investigation is characterised, as field research, of exploratory-descriptive combined type. Environment and participants: the research subjects, seven students in the first semester of an engineering course offered by a private institution in the state of São Paulo, with an interest in following the control and automation qualification, participated voluntarily in the study. Data collection and analysis: three synchronous meetings were held in remote modality. For data collection, we used audio and video recordings of the discussions and the written productions of the students in such moments. In this article, we present the analysis of the first meeting. Results: We evidenced, among other aspects, cognitive dysfunctions that can lead to obstacles in the transposition of mathematical knowledge to extra-mathematical contexts. Conclusions: The results obtained allow, in the future, the planning of adequate mediations so that the teacher can help the students to convert the identified dysfunctions into sufficiently developed cognitive functions.
A szakmai továbbképzések szerepe az angoltanár-képzésben oktatók IKT készségfejlesztésében: longitudinális esettanulmány a magyar felsőoktatási kontextusban a Covid-19 idején
Authors: Fekete Imre , Divéki Rita
Published: March 2023

A jelen kutatás célja egy szakmai továbbképzés-sorozat szerepének bemutatása egy olyan hazai felsőoktatási intézmény angol tanszékének életében, ahol az oktatók részt vesznek mind az anglisztika alapképzésben, mind az angoltanár-képzésben tanuló hallgatók oktatásában, s ahol nem működik módszertani fejlesztőközpont. Leibowitz (2014) értelmezése szerint a szakmai fejlődés (academic development) fogalmának univerzális meghatározása nehéz vállalkozás, mert fogalmi keretei gyorsan változnak, valamint rendkívül kontextusérzékenyek. Ezért a kontextus figyelembevételével jelen esetben a szakmai továbbképzéseket olyan közös szakmai eseményeknek (workshopoknak) tekintjük, amelyeken azonos képzésben oktató tanárok saját pedagógiai készségeik fejlesztését szolgáló tevékenységeket végeznek. Ezek a tevékenységek lehetnek eszmecserék új oktatásmódszertani lehetőségekről, azok aktív kipróbálása védett környezetben, illetve a folytatólagosság tekintetében az egyes, valós tanulási helyzetben is kipróbált módszerek reflektív értékelése. Mivel jelen esetben a továbbképzésekre belső igény mutatkozott, és a részvétel az eseményeken végig önkéntes volt, önszerveződő szakmai továbbképzés-sorozatról van szó. Jelen tanulmány bemutatja, miért döntöttek úgy az esettanulmányban részt vevő tanszék oktatói, hogy önszerveződő szakmai továbbképzéseket szerveznek, valamint több lépcsőben, hosszú távon nyomon követik a résztvevők tapasztalatait. A továbbképzésekre a 2020 tavaszán hirtelen elrendelt intézménybezárások miatt 2020 őszén került sor, majd két lépcsőben, 2021 tavaszán és 2022 tavaszán utánkövető interjúk formájában gyűjtöttük a résztvevők tapasztalatait. Ezt kiegészítve a továbbképzések anyagával, valamint a kutató-résztvevők megfigyeléseivel, a kutatás három fő területre fókuszál: (1) mi motiválta a tanszék oktatóit a továbbképzések megszervezésére és az azokon történő részvételre, (2) milyen meglátásaik voltak a továbbképzésekről (hasznosnak bizonyultak-e, segítették-e a munkájukat), valamint (3) mennyire sikerült hosszú távon integrálni a továbbképzés során megszerzett ismereteket saját tanítási gyakorlatukba.

Az iskolai kudarcnak (school failure) igen sok értelmezése vált ismertté az elmúlt évtizedekben, melyek nemcsak bővítették e kudarcélmény okainak eredetileg szűk körét, hanem lehetővé tették személyes (kognitív és nem kognitív) és környezeti (családi és iskolai) dimenziók szerinti értelmezését, illetve ezen dimenziók egymásra gyakorolt hatásának vizsgálatát is. A kutatások eredményei rámutattak arra, hogy egy igen komplex jelenségről van szó, melynek egyéni és rendszerszintű kezelése kizárólag e komplexitás figyelembevételével lehet hatékony és eredményes (pl. Berliner, 2009; Herbert, 1996; Keddie, 1973; Petridou & Karagiorgi, 2016;Paksi et al., 2020; Turkheimer et al., 2003).Az elméleti tanulmány célja bemutatni az iskolai kudarc főbb értelmezési kereteit, kiemel-ten azokat, amelyek a társas kontextusban jelentkező kognitív pszichológiai jellemzők mellett hangsúlyosabban foglalkoznak a nem kognitív jellemzőkkel, hiszen egyre több vizsgálati eredmény (pl. Heckman & Rubinstein, 2001; Ibabe, 2016; Paksi et al., 2020) hívja fel a figyelmet e jellemzők kudarcélményben és iskolai lemorzsolódásban (dropping out) játszott szerepére. A tanulmányban ismertetjük az ezen megközelítések mentén általunk kialakított kutatási modellt is, mely alapját képezi egy 2021–2025 között megvalósítandó négyéves longitudinális kutatásnak és fejlesztési munkának általános iskolai (7–14 éves) tanulók és pedagógusaik körében.

Abstract: The financial achievements of outstanding athletes are not directly proportional to the finances of the coaches who have driven these athletes' careers. It is necessary to develop an application that can link the influence between athlete achievement and coach marketing. When athletes get achievements, coaches also get additional job opportunities to increase their financial income. The purpose of this research and development is to develop the Sport Human Connection (SHC) application as a marketplace for publication and marketing of sports coach services. Research and development was chosen for this research method by involving 40 samples of sports trainers spread across various provinces in Indonesia. Sports trainers state that the SHC application with all its features can help the publication and marketing of the sports coach profession. As well as significantly, the marketing of sports trainers is more effective by using the SHC application than using the conventional methods used by sports coaches before. It can be concluded that the SHC application can help the publication and marketing of sports trainers which can provide additional job opportunities and financial income. For this reason, it is necessary to hold an audience with the Indonesian government so that the use of the SHC application obtains a policy and can be disseminated to sports coaches throughout Indonesia.

Abstrak: Financial atlet berprestasi belum berbanding lurus dengan financial pelatih-pelatih yang mengantarkan karier atlet tersebut. Perlu dikembangkan sebuah aplikasi yang bisa menghubungkan pengaruh antara prestasi atlet dengan pemasaran pelatih. Ketika Atlet memperoleh prestasi, pelatih juga mendapat peluang pekerjaan tambahan untuk meningkatkan pendapatan finansialnya.  Tujuan penelitian dan pengembangan ini adalah mengembangkan aplikasi Sport Human Connection (SHC) sebagai marketplace untuk publikasi dan pemasaran layanan pelatih olahraga. Research and development dipilih untuk metode penelitian ini dengan melibatkan 40 sampel pelatih olahraga yang tersebar di berbagai provinsi di Indonesia. Pelatih olahraga menyatakan bahwa aplikasi SHC dengan semua fiturnya mampu membantu publikasi dan pemasaran profesi pelatih olahraga. Serta secara signifikan, pemasaran pelatih olahraga lebih efektif dengan menggunakan aplikasi SHC daripada menggunakan cara konvensional yang digunakan para pelatih olahraga sebelumnya. Dapat disimpulkan bahwa aplikasi SHC bisa membantu publikasi dan pemasaran pelatih olahraga yang mampu memberikan peluang pekerjaan dan pendapatan finansial tambahan.

Under-treatment of Pain in Black Patients: A Historical Overview, Case-based Analysis, and Legalities as Explored Through the Tenets of Critical Race Theory
Authors: Habib Muhammad Hamza
Published: March 2023

Pain, also called the “fifth vital sign” is an important topic in healthcare settings. It requires urgent attention and treatment to minimize agony and discomfort. Unfortunately, multiple clinical studies conducted over the last few decades have repeatedly shown disparately inferior pain management in Black patients in medical settings when compared to White patients with similar pain levels. This Article utilizes Critical Race Theory to examine the understudied issue of under-treatment of pain in Black patients. It discusses the story of a real patient, Jacqui, who was under the medical care of the author. It examines her unfortunate experiences with poor pain management throughout different stages of her life, including a blood disorder as a child with, a traumatic arm fracture as a teen, during childbirth, and finally, later in life with advanced cancer. Three points are addressed in this Article: first, a discussion of Jacqui’sexperiences, and an analysis of those experiences through the available clinical data. This Article reveals the extent to which Black patient’s pain is undertreated, and how it led Black patients to mistrust our healthcare system. Second, the Article explores malpractice based legal analyses to these issues based on federal and state legislation. Third, various proposals to correct various systemicdiscrepancies in medical-education and clinical settings to minimize such racial biases in pain management are discussed. It concludes by talking about the final part of Jacqui’s clinical journey.
Pyrolysis Simulation of Plastic Wastes in Actual Situation
Authors: Wang Zijian
Published: March 2023

Nowadays, the physical and chemical qualities of the same type of plastic goods can vary significantly due to production conditions and manufacturing processes, making it difficult to categorize discarded plastic products and increasing the difficulty of recycling. In this paper, three thermoplastics: polypropylene (PP); polystyrene (PS); and high-density polyethylene (HDPE), are used to detect and analyze the pyrolysis properties of waste plastics using Thermogravimetric Analysis (TGA) and to calculate the kinetic parameters of thermoplastics in the pyrolysis reaction. It is found that the mixed pyrolysis of plastics facilitates the pyrolysis reaction, but the required activation energy of the reaction increases if the content of more stable HDPE gains. The optimum pyrolysis temperature range and activation energy of pyrolysis are discovered by modelling the real proportion of waste plastics and pyrolyzing them. And the results will predict and guide the engineering development for mass waste plastic pyrolysis.
