Stem Cell Therapy for Brain Tumors
Authors: Aleynik Alexander , Rameshwar Pranela
Published: April 2024

Glioblastoma multiforme (GBM), the most common and lethal brain cancer, prognosis remains bleak with a median survival of about 15 months despite maximal surgical resection, radiotherapy, and temozolomide treatment. The difficulty associated with safely and effectively delivering therapeutics across the blood brain barrier (BBB) is a major challenge towards GBM treatment. Ongoing research and clinical trials, including attempts to deliver therapeutics within stem cells present possible solutions. The relationships between brain cancer pathology, stem cell properties, therapeutic advantages and disadvan- tages of various stem cell types, drug delivery methods, cancer stem cells, gene therapy, anti-cancer vaccines, chimeric antigen receptor therapies, and combination therapies are discussed.

A Theory of Gravitational Generation to Mitigate Space-Induced Low Gravity – Relevance to Premature Aging in Space
Authors: Rangdal Anish , Petryna Andrew , Shadpoor Bobak , Sherman Lauren S. , Homsi Emile
Published: April 2024

Artificial gravity is among the key goals for successful long-term space exploration. Over the last century, several possible theoretical models have been proposed. As far as we are aware, use of centrifugal rotation is the only major form of artificial gravity that has been significantly tested. There are disadvantages to this system including the high degree of speed needed to produce a force to recapitulate earth’s gravitational field. We tested the potential efficacy of diamagnetic levitation as a form of artificial gravity. This study capitalized on its unique capacity to uphold desired aesthetic attributes while adjusting gravitational forces per specific conditional requirements. The model emphasized on methods by which diamagnetic levitation negate the detrimental consequences of prolonged weightlessness on human physiology, leading to premature age. By offering a detailed exploration of the potential of diamagnetic levitation and its implications, this research contributes to a deeper understanding of the critical role of the potential for artificial gravity on long-term visit to space. The findings and insights presented herein serve as a valuable resource for future space missions and the development of space habitation technologies, guiding interdisciplinary scientists towards the realization of safer, healthier, and more sustainable human ventures beyond earth’s confines. We discussed the positive impact on premature aging for long-term habitation in space.

Visual arts education in pre-school and integrated education has an integrating role in relation to most areas of education. In the early period of mental development, the visual arts, along with speech, become the basic form of expression for children
and a factor in the development of creative thinking. This period of children's mental development is called the age of expression in connection with the strong need to express oneself through creative plastic activity. Reasoning then becomes a cognitive activity and artistic expression becomes a basic form of expression. Visual arts education should be a permanent part of teaching and parenting activities. It is especially important at the elementary level when children make a mental breakthrough and cognitive processes intensify.
and cognitive processes are intensified, making most of them ready for learning, which gradually becomes their primary form of activity.
The main aim of the study is to present visual arts education as one of the
one of the most important forms of activity of the pre-school and early school-age child and to indicate that artistic creativity results from the child's psychological needs manifested in all forms of activity and is the driving force behind the development of the young person.
Visual creativity is a process of making a difference, the best strategy for guiding development. This assumption compels us to explore the essence of creativity both
in terms of creations and works, as well as the developmental mechanisms conditioning the creative process The influence of the first years of life on the later behaviour and actions of an adult is a scientifically proven fact. Young children's creativity is linked to his or her own concrete experience and forms the basis of a research attitude. By drawing, the child tells and explains, at the same time discovers himself and expresses his world; he is by nature a creator. Children's expression is a form of manifestation of the child's creative attitude.
The Nose at the Crossroads: An Intersectional Reading of the Pseudo-Vergilian Moretum
Authors: Bellei Francesca
Published: April 2024

summary: This article provides a new interpretation of the anonymous poem Moretum as erotic satire. Mindful of Shelley Haley's invitation to read it through a Black feminist lens, this article turns to recent Black feminist scholarship on pornography to argue that the presence of sex does not automatically negate the agency of Scybale, the African woman described in the poem as Simulus's custos . Further, I review the evidence for Simulus's own identity. Through a combination of Audre Lorde's Black queer lens and Paul Preciado's trans scholarship on the dildo, I further argue that by imagining Simulus as Black, queer, and/or trans, the power imbalance between Simulus and Scybale is greatly reduced. Lastly, I heed Haley's invitation to read Black protagonists of Latin poetry through Yoruba mythology, and turn to Henry Louis Gates Jr. to argue that Simulus's Blackness brings them closest to Esu, the genderqueer trickster god, which in turn helps us identify him with the author themselves.
Owning the Libs: The Contemporary Politics of Envy
Authors: Johnson Paul
Published: April 2024

Abstract: This essay defines Owning the Libs (OTL), a logic of envy, characterized by a subject's need to both deny another enjoyment and to frustrate the capacity of these political opponents to live. My case studies focus on reactions to progressive protests in the post-Ferguson environment. OTL is not downstream of some cultural war nor an exotic right-wing, illiberal phenomenon. Situating personhood in the tradition of violent dispossession, I illuminate the practice's liberal roots, before concluding OTL will be (if it is not already) US conservatism's policy agenda, and an existential threat to progressive agitation.
The Misbegotten Critique of the Model Minority Myth
Authors: Kim Claire
Published: April 2024

Abstract: I argue in this article that Asian Americanists' standard critique of the "model minority myth" does more harm than good and should therefore be abandoned. I show that the critique misses the forest for the trees, disavowing structural anti-Blackness and the differentiated positioning of Asian Americans and Black people that it produces, thereby misconceiving the stakes and function of model minority discourse. What I offer here, then, is a critique of the critique of model minority discourse—as well as suggestions for how to re-assess such discourse in relation to anti-Blackness.
Intercomparison of flux-, gradient-, and variance-based optical turbulence (C
n2) parameterizations
Authors: Pierzyna Maximilian , Hartogensis Oscar , Basu Sukanta , Saathof Rudolf
Published: April 2024

For free-space optical communication or ground-based optical astronomy,
ample data of optical turbulence strength (C
n
2) are imperative but typically scarce.
Turbulence conditions are strongly site dependent, so their accurate
quantification requires in situ
measurements or numerical weather simulations. If C
n
2 is not measured directly (e.g., with
a scintillometer), C
n
2 parameterizations must be utilized to
estimate it from meteorological observations or model output. Even
though various parameterizations exist in the literature, their
relative performance is unknown. We fill this knowledge gap by
performing a systematic three-way comparison of a flux-, gradient-,
and variance-based parameterization. Each parameterization is applied
to both observed and simulated meteorological variables, and the
resulting C
n
2 estimates are compared against
observed C
n
2 from two scintillometers. The
variance-based parameterization yields the overall best performance,
and unlike other approaches, its application is not limited to the
lowest part of the atmospheric boundary layer (i.e. the surface
layer). We also show that C
n
2 estimated from the output of the
Weather Research and Forecasting model aligns well with observations,
highlighting the value of mesoscale models for optical turbulence
modeling.

Published: April 2024

This study introduces a cutting-edge fiber-optic dosimetry (FOD) sensor designed for measuring radiation in biological settings. The accuracy and precision of dosimeters for small animals, particularly prolonged exposure to nonuniform radiation fields, are always challenging. A state-of-the-art in-vivo dosimeter utilizing glass-encapsulated Thermoluminescence cylindrical detector (TLD) was introduced. The FODs are implanted into the rat during a prolonged irradiation scenario involving 137Cs where the rat has the freedom to move within a heterogeneous radiation domain. The implantation surgery was verified with X-ray computed tomography (CT) in addition to biochemical and pathological tests to assess the biocompatibility of FOD in vivo. A versatile FOD is designed for industrial and medical fields, which demand accurate and resilient radiation dosimeters. The dose measurements are associated with precise two-dimensional (2D) radiation distribution imaging. Three cylindrical FODs and three standards TLD_100 for each rat were tested. The measurements of peak irradiation before and after exposure reveal greater stability and superior sensitivity when compared to standard thermo-luminescence detectors in an in-vivo animal test. To the best of our knowledge, FOD testing on live animals is presented for the first time in this paper. Regarding the safety and biocompatibility of FOD, no morphological signs with any kind of inflammation or sensitivity toward the FOD material have been remarked. Moreover, with the current FOD, there is no oedema between the epidermal, dermal, and subdermal sections at the site of implantation. The results also show the stable levels of white blood cells (lymphocytes, granulocytes, MID) as blood inflammatory markers before surgery and at the time of extraction of the implanted dosimeters, thus confirming the biocompatibility for each optical fiber cylinder dosimeter. As a result, the new dosimeters have excellent biocompatibility in living tissues and have 100% accurate reusability intensity of the delivered radiation doses compared to TLD_100 which demonstrated a 45% reduction in its intensity accuracy.

Published: April 2024

Three-dimensional tomographic reconstruction requires careful selection of the illumination angles, often under certain measurement constraints. When the angular distribution must be nonuniform, appropriate selection of the reconstruction weights is necessary. We show that Voronoi weighting can significantly improve the fidelity of optical diffraction tomography.
Impact of external moisture on quantitative analysis of coal and rapid drying by a CO2 laser to improve prediction accuracy based on laser induced breakdown spectroscopy

Published: April 2024

For high-accuracy determination of ash, fixed carbon, and volatile matter in coal, generally, the impact of external moisture content in coal must be considered and removed in quantitative modeling based on laser-induced breakdown spectroscopy (LIBS). Herein, the ash, fixed carbon, and volatile of coals with moisture contents from 3% to 15% are quantitatively assessed using partial least squares based on principal component analysis (PCA-PLS), and the predictive limit of this model for moist coals is explored based on LIBS. To validate the industrial feasibility of the method, an infrared CO2 laser based heating technique is employed to rapidly dry the moist coals before laser ablation. The results demonstrate that root mean square error of prediction (RMSEP) of all ash, volatile carbon, and fixed carbon become higher with moisture content increase. Nevertheless, as the moisture content reaches 3%, the prediction model retains an acceptable predictive capability with mean absolute error (MAE) of ash, volatile matter, and fixed carbon of 1.85%, 1.5%, and 1.79%, respectively. When the IR laser for drying is employed to irradiating for 40 ms, external water in coal with an original moisture content of 15% can be quickly removed, resulting in a decrease in RMSEP of ash, volatile matter, and fixed carbon from 3.06%, 5.42%, and 6.22% to 1.47%, 3.16%, and 3.34%, respectively. This method provides a potential technical solution for the use of infrared laser-assisted LIBS real-time online rapid detection of indicators in raw coal with high moisture content.
Regulation of multiple exceptional points in a plasmonic quadrumer
Authors: Peng Yiwei , Yang Yumeng , Chen Hongsheng , Li Yuanzhen , Gao Fei
Published: April 2024

Exceptional points (EPs), which signify the singularity of eigenvalues and eigenstates in non-Hermitian systems, have garnered considerable attention in two-state systems, revealing a wealth of intriguing phenomena. However, the potential of EPs in multi-state systems, particularly their interaction and coalescence, has been underexplored, especially in the context of electromagnetic fields where far-field coupling can revolutionize spatial wave control. Here, we theoretically and computationally explore the coalescence of multiple EPs within a designer surface plasmonic quadrumer system. The coupled mode model shows that the multiple EPs can emerge and collide as the system parameters vary, leading to higher-order singularities. Numerically calculated results showcase that multiple EPs with different orders have special far-field responses. This pioneering strategy heralds a new era of wavefront engineering in non-Hermitian photonic structures, presenting a transformative class of radiative systems that transcend the conventional frequency spectrum from microwave to optical realms.
A bidirectional broadband multifunctional terahertz device based on vanadium dioxide
Authors: Li Tong , Liang Xiangan , Bao ChengQin , Huang Pan , He Qian , Song Guofeng
Published: April 2024

We propose a bidirectional and switchable terahertz absorber/reflector, utilizing vanadium dioxide. Detailed simulations reveal that the device is capable of achieving broadband absorption and reflection by manipulating the phase state of vanadium dioxide. Specifically, when vanadium dioxide is in its insulating phase, the device exhibits exceptional bidirectional broadband absorption characteristics, with an absorptivity exceeding 90% across a frequency range of 1.9 THz to 10 THz for both forward and backward TE/TM-polarized incident waves. Notably, this absorption behavior remains robust regardless of the polarization angle of the incident wave. When vanadium dioxide transitions to its metal phase, the device demonstrates a reflectivity of over 90% in the lower frequency range for forward and backward TE-polarized incident waves. In the higher frequency range, the device exhibits both reflection and absorption effects for TE-polarized waves. The performance of the device is insensitive to the angle of incidence of electromagnetic waves whether the vanadium dioxide is in the insulating or metallic phase. Furthermore, when the device is used as an absorber (reflector), changes in vanadium dioxide conductivity do not affect the stable performance of the device at high (low) frequencies. Given its versatility and high efficiency, the device has promising applications in a number of fields such as terahertz energy harvesting, sensing, optical switching and shielding.

Published: April 2024

People living with chronic hepatitis B (PLCHB) are recommended to follow a lifelong monitoring regimen and face increased risk of liver cancer. Additionally, PLCHB frequently encounter stigma and discrimination, and relationship disruptions because of their chronic hepatitis B (CHB). Social support plays a key role in coping with chronic illnesses; however, this is inadequately assessed for PLCHB. This study aims to assess the physical, social, and mental impacts of living with CHB, the strategies PLCHB utilize to cope with their disease, and how social support–or lack of–impacts their journey with hepatitis B. The study was promoted through the Hepatitis B Foundation social media platforms, interested individuals filled-in a form expressing their interest to participate. The researcher conducted 24 telephone interviews in English, with PLCHB ≥18 years of age residing in the United States (U.S.) and Canada. Questions focused on the lived experiences of CHB and explored social support mechanisms that helped PLCHB. PLCHB experience a wide range of impacts (physical, social, and mental) that negatively affect their quality of life. Participants reported that receiving social support from their close network of individuals, hepatitis B community, or healthcare providers positively influenced their perspective on their future health and helped them adhere to treatment. The physical, social, and mental impacts of living with hepatitis B significantly affect the quality of life of PLCHB, calling for more research to document these impacts, and design integrated care models to address them. Social support appears to play an essential role in helping PLCHB cope with their disease and should be further studied.
A fractional perspective on the transmission dynamics of a parasitic infection, considering the impact of both strong and weak immunity
Authors: Tang Tao-Qian , Jan Rashid , Shah Zahir , Vrinceanu Narcisa , Tanasescu Ciprian , Jan Asif
Published: April 2024

Infectious disease cryptosporidiosis is caused by the cryptosporidium parasite, a type of parasitic organism. It is spread through the ingestion of contaminated water, food, or fecal matter from infected animals or humans. The control becomes difficult because the parasite may remain in the environment for a long period. In this work, we constructed an epidemic model for the infection of cryptosporidiosis in a fractional framework with strong and weak immunity concepts. In our analysis, we utilize the well-known next-generation matrix technique to evaluate the reproduction number of the recommended model, indicated by R 0. As R 0 < 1, our results show that the disease-free steady-state is locally asymptotically stable; in other cases, it becomes unstable. Our emphasis is on the dynamical behavior and the qualitative analysis of cryptosporidiosis. Moreover, the fixed point theorem of Schaefer and Banach has been utilized to investigate the existence and uniqueness of the solution. We identify suitable conditions for the Ulam-Hyers stability of the proposed model of the parasitic infection. The impact of the determinants on the sickness caused by cryptosporidiosis is highlighted by the examination of the solution pathways using a novel numerical technique. Numerical investigation is conducted on the solution pathways of the system while varying various input factors. Policymakers and health officials are informed of the crucial factors pertaining to the infection system to aid in its control.

Published: April 2024

The Communist Party of China’s 19th National Congress underlined the necessity of speeding the development of a manufacturing powerhouse and advanced manufacturing sector by supporting the deep integration of the Internet, big data, artificial intelligence, and the real economy. This study employed principal component analysis to extract the prominent risk factors from questionnaire data in order to manage the risks connected with the Internet strategic transformation of manufacturing firms. To confirm the major risk factors, a structural equation modeling was created using Amos-24 software. The findings revealed that risk factors of Internet strategic transformation in manufacturing businesses are mostly expressed in equipment flexibility risks, organizational versatility risks, smart technology risks, Internet technology risks, flexible management risks, and financing management risks. The paper offers useful theoretical and practical insights into the risks of China’s manufacturing businesses’ Internet strategic transformation. The findings can assist manufacturing firms in better identifying and managing these risks, supporting their smooth transition to the Internet economy.
Postpartum versus postnatal period: Do the name and duration matter?
Authors: Kumarasinghe Malith , Herath Manoja P. , Hills Andrew P. , Ahuja Kiran D. K.
Published: April 2024

Introduction

Guidelines and other strategic documents were collated to understand the extent of the global use of terms postpartum and postnatal along with the duration and schedule of maternal care after delivery.

Methods

Postpartum care guidelines and strategies published in English, by international organisations including the World Health Organization, and countries in either the Organization for Economic Co-operation and Development or Group of 20 were included in this scoping review. All documents available online with unrestricted access and published before May 31, 2023, were included. The evolution of the World Health Organization’s definition of the period after delivery for mothers and the changes in the schedule of routine maternal care following delivery over time were displayed pictorially. A summary table was then developed to present the level of similarities and differences in the latest available documents from the international organisations and countries belonging to either the Organisation for Economic Co-operation and Development or the Group of 20.

Results

Ten documents from the World Health Organization, one from the European Board, and 15 country-level guidelines from six countries met the inclusion criteria. The interchangeable use of ‘postpartum’ and ‘postnatal’ is common. While the World Health Organization mentions the definitive length (six weeks) of the postpartum/ postnatal period, it is not stated in documents from other organisations and countries. Additionally, the length and schedule of routine maternal care after delivery vary substantially between organisations/countries, spanning from six weeks to one year with two to six healthcare contacts, respectively.

Conclusion

Through this review, we make a case for a universal harmonisation of the term postpartum when referring to mothers after delivery; add clarity to the documents on the rationale for and duration of the postpartum period; and extend the routine maternal care schedule after delivery to support women in this vulnerable period.
Blood glucose fluctuation and in-hospital mortality among patients with acute myocardial infarction: eICU collaborative research database
Authors: Chen Junhua , Huang Weifang , Liang Nan
Published: April 2024

Background

To assess the relationship between glycemic variability, glucose fluctuation trajectory and the risk of in-hospital mortality in patients with acute myocardial infarction (AMI).

Methods

This retrospective cohort study included AMI patients from eICU Collaborative Research Database. In-hospital mortality of AMI patients was primary endpoint. Blood glucose levels at admission, glycemic variability, and glucose fluctuation trajectory were three main study variables. Blood glucose levels at admission were stratified into: normal, intermediate, and high. Glycemic variability was evaluated using the coefficient of variation (CV), divided into four groups based on quartiles: quartile 1: CV≤10; quartile 2: 10<CV≤20; quartile 3: 2030. Univariate and multivariate Cox regression models to assess the relationship between blood glucose levels at admission, glycemic variability, glucose fluctuation trajectory, and in-hospital mortality in patients with AMI.

Results

2590 participants were eventually included in this study. There was a positive relationship between high blood glucose level at admission and in-hospital mortality [hazard ratio (HR) = 1.42, 95%confidence interval (CI): 1.06–1.89]. The fourth quartile (CV>30) of CV was associated with increased in-hospital mortality (HR = 2.06, 95% CI: 1.25–3.40). The findings indicated that only AMI individuals in the fourth quartile of glycemic variability, exhibited an elevated in-hospital mortality among those with normal blood glucose levels at admission (HR = 2.33, 95% CI: 1.11–4.87). Additionally, elevated blood glucose level was a risk factor for in-hospital mortality in AMI patients.

Conclusion

Glycemic variability was correlated with in-hospital mortality, particularly among AMI patients who had normal blood glucose levels at admission. Our study findings also suggest early intervention should be implemented to normalize high blood glucose levels at admission of AMI.

Published: April 2024

Since the pandemic started, organisations have been actively seeking ways to improve their organisational agility and resilience (regility) and turn to Artificial Intelligence (AI) to gain a deeper understanding and further enhance their agility and regility. Organisations are turning to AI as a critical enabler to achieve these goals. AI empowers organisations by analysing large data sets quickly and accurately, enabling faster decision-making and building agility and resilience. This strategic use of AI gives businesses a competitive advantage and allows them to adapt to rapidly changing environments. Failure to prioritise agility and responsiveness can result in increased costs, missed opportunities, competition and reputational damage, and ultimately, loss of customers, revenue, profitability, and market share. Prioritising can be achieved by utilising eXplainable Artificial Intelligence (XAI) techniques, illuminating how AI models make decisions and making them transparent, interpretable, and understandable. Based on previous research on using AI to predict organisational agility, this study focuses on integrating XAI techniques, such as Shapley Additive Explanations (SHAP), in organisational agility and resilience. By identifying the importance of different features that affect organisational agility prediction, this study aims to demystify the decision-making processes of the prediction model using XAI. This is essential for the ethical deployment of AI, fostering trust and transparency in these systems. Recognising key features in organisational agility prediction can guide companies in determining which areas to concentrate on in order to improve their agility and resilience.
Structural equation modeling for the effects of family dysfunctions and communication on perceived mental health status among under/graduate students in the U.S.
Authors: Shon En-Jung , Lee Lena
Published: April 2024

Background

Many of the college students expressed experiencing moderate or severe psychological distress. In their emergence as adults, college students encounter significant periods of drastic change. Family functions play a crucial role in determining individuals’ mental health status.

Objectives

The first objective of this study was to investigate whether family communication mediates the relationships between family dysfunctions and perceived mental health status among under/graduate students. The second objective was to investigate whether the mediation effects of family communication on the relationships between family dysfunctions and perceived mental health status differ by gender.

Methods

The current study applied Minuchin’s Structural Family Theory with under/graduate students (N = 348) in Ohio. Structural Equation Modeling was conducted to examine the effects of family dysfunctions and communication on perceived mental health status among under/graduate students.

Results

Disengaged family function significantly influenced family communication, which, in turn, significantly impacted perceived mental health (mediation effect). Enmeshed family function did not show a significant relationship with family communication, whereas family communication had a significant impact on perceived mental health (no mediation effect). The model comparison test indicated that there were differences between males and females: the structural weights of the current path models were consistent with the full models, and there was a significant difference in the effect of parents’ marital status on perceived mental health, with males being significantly impacted in both models.

Conclusions

Practitioners should recognize that improving positive communication skills within the family unit can be a realistic approach to supporting the perceived mental health of under/graduate students. Colleges/universities should offer regular education programs to promote an understanding of the relationship between family communication strategies and the mental health of under/graduate students.
Angol nyelvű olvashatósági formulák magyar nyelvi adaptálásának lehetséges irányai
Authors: Bogdán Patrik
Published: April 2024

Az olvashatóság olyan szövegjellemző, amely előrejelzi a szöveg olvasásának nehézségi fokát, megmutatva, milyen nehezen lehet annak információit kinyerni. Az olvashatóság kutatása ezért az oktatás során használt szövegek esetében nélkülözhetetlen. Az olvashatósági formulák célja ezen jellemző matematikai úton történő meghatározása (DuBay 2004). Magyar nyelvű szövegeken alkalmazható formula még nem készült. Ezért jelen tanulmány célja az olvashatóság alapvető elméleti kereteinek áttekintése, a formulák rendszerezése változóik alapján. Ezért a szakirodalmi elemzés során először az olvashatóság és az olvasható szöveg meghatározásait járjuk körbe, majd a leggyakrabban használt amerikai formulák közül ötöt bemutatva szemléltetjük azok működési elveit, magyar nyelvű adaptációjuk lehetséges irányait, végül pedig a formulákat érő leggyakoribb kritikákat ismertetjük. Legfontosabb megállapításaink összefoglalása: Bármely szöveg három jellemző kölcsönhatása révén válik olvashatóvá – a szöveg tartalma és szerkezete; az olvasó olvasásértési képessége, motiváltsága és tudása; a vizsgálat célja és jellege –, amelyek közül az olvashatósági formulák az elsőre fókuszálnak, különböző számítási módszerek segítségével (Dale és Chall 1949). A formulák közelebbi vizsgálata során ezen módszereket a mért változók mentén három csoportba rendszereztük, melyek a (1) szófamiliaritáson alapuló, a szóhosszúságot (2) szótagszámban és (3) betűszámban mérő formulák. A magyar nyelvi adaptálhatóság szempontjából a harmadik csoport bizonyul legcélszerűbb kiindulópontnak. Az összefoglalt elméleti keret és a formulák rendszerezése a formulák magyar nyelvi adaptációját, az olvashatóság hazai diskurzusának kibontakoztatását hivatott elősegíteni.
Sob os augúrios de Mnemosyne: Menina que vem de Itaiara, de Lindanor Celina
Authors: Pinho Relivaldo
Published: April 2024

Estuda-se o primeiro romance de Lindanor Celina, Menina que vem de Itaiara, de 1963, que narra a trajetória da menina Irene na cidade de Itaiara. Apesar de certo reconhecimento, especialmente da relação de seus elementos ficcional e histórico, a literatura de Celina ainda é pouco estudada e isso se aplica a esse livro. Tomam-se teorias e conceitos de pensadores, como Paul Ricoeur, Platão, Aristóteles, Maurice Halbwachs, e de outros autores que tratam sobre as características históricas, socioculturais e ficcionais da região paraense, para analisar o cerne, ainda não detidamente estudado, desse romance, o estatuto da memória. No livro, a memória está, em seus vários aspectos, relacionada à reminiscência, à imaginação/representação do vivido e à narração. É a narração – na interseção da literatura com as dimensões histórico-sociais regionais – a responsável por rememorar os eventos e personagens exemplares e arquetípicos da cidade.

Teatro e suas técnicas: uma prática inclusiva na Arteterapia com alunos da Educação Especial
Authors: Malaquias Leandro Jesus
Published: April 2024

Este texto tem como objetivo fazer uma reflexão sobre as técnicas teatrais desenvolvidas com crianças especiais no âmbito educacional. Trazer o teatro para a escola e direcionando-o para educação especial significa criar mecanismo de organização pedagógica para o seu desenvolvimento, dotando a instituição escolar de espaços e tempos curriculares para educadores e educandos buscarem seus saberes estéticos. Esse trabalho justifica-se porque o teatro é um instrumento eficaz na utilização da arte como terapia, pois através dela é possível os alunos exercitarem suas expressões e suas emoções utilizando o corpo como um dos instrumentos de trabalho. O teatro dentro da Arteterapia deve ser entendido como uma prática pedagógica que conduza os alunos perante as suas especificidades a encontrar um caminho para a criatividade. Ela proporciona o aprendizado pela manifestação da imaginação criativa na realidade, pois reúne a sensibilização e a conscientização por meio de jogos, brincadeiras, movimentos corporais, posturas e atitudes. No âmbito da educação especial, o teatro é visto como insuficientemente desenvolvido nas escolas durante as aulas de Arteterapia, pois, aos profissionais da área, em sua maioria com formação em Artes Visuais falta o entendimento de que ela também pode ser uma ferramenta útil no processo de ensino-aprendizagem do aluno.

O texto discute a Fisiologia Humana de uma perspectiva transdisciplinar, em diálogo com as artes. O conteúdo teórico, que vai desde a origem do Universo e da vida até o movimento humano, mistura-se aos atravessamentos do Isolamento Social consequente à Pandemia da Covid-19. Ficar em casa traz reminiscências dos tempos de escola, enquanto canções da MPB compõem a trilha sonora. Durante o ensino remoto mediado por equipamentos eletrônicos, estimular o interesse é uma demanda urgente.
Desafios na jornada docente: O aparecimento silencioso da Síndrome de Burnout
Authors: GONÇALVES DALILA DA COSTA , Ribeiro Wilian , Gonçalves Débora
Published: April 2024

A crescente desistência da sala de aula tem demonstrado quão desgastada e desvalorizada tem se tornado a profissão docente. Junto a fatores de pressão por alto desempenho em meio a um cenário pandêmico, o sistema político-educacional produz colapsos psíquicos e físicos em seus profissionais. Discute-se muito acerca da efetividade do ensino e aprendizados dos discentes, contudo,  pouco  se  aborda sobre as condições de trabalho e os reflexos na saúde dos  professores. Este artigo tem   por  objetivo   refletir   sobre   o desgaste dos professores e correlaciona-lo ao aparecimento  da Síndrome de Burnout. Baseada em uma revisão de literatura, buscamos compreender e identificar os primeiros sintomas e as consequências físicas e emocionais geradas pelas condições do sistema educacional. O desgaste vocal, físico e mental, extensa jornada de trabalho, além da remuneração insatisfatória, reinvenção pedagógica diante do isolamento social, o não reconhecimento social e a pressão por alta performance em meio a pandemia do Covid-19, são algumas das  supostas evidências que podem estar diretamente relacionadas ao  desenvolvimento da síndrome de Burnout.

Buscando mitigar os problemas de ensino-aprendizagem ocasionados pela suspensão das aulas presenciais na pandemia de Covid-19, diferentes universidades e grupos de educação adotaram estratégias identificadas como “atividades de ensino remoto emergencial”. Partindo de uma perspectiva freiriana, este artigo avalia uma dessas experiências, desenvolvida dentro de uma Instituição Federal de Ensino Superior (IFES), a partir da leitura de mundo realizada pelos estudantes envolvidos. Para isso, apresenta e discute os dados obtidos em grupos focais online realizados com 140 graduandos, estabelecendo diálogo com os estudos sobre experiências semelhantes desenvolvidas no Brasil. Os resultados indicam que, para a maior parte dos discentes, as atividades remotas trouxeram prejuízos em relação à aprendizagem e problemas de saúde. A análise dos dados permite inferir que, embora tenha sido relevante no período de isolamento, o modelo adotado pela IFES reproduziu a educação bancária presente no modelo presencial e não trouxe benefícios que justifiquem sua continuidade no pós-pandemia.
Docentes e as relações entre trabalho remoto e competências socioemocionais na pandemia de Covid-19
Authors: LAPA JUNIOR LUIZ GONZAGA
Published: April 2024

O objetivo deste artigo é relacionar percepções do trabalho remoto e competências socioemocionais de docentes de um município do Estado de Goiás. Para as percepções do trabalho remoto foi construído um questionário específico e utilizou-se a Escala de Competências Socioemocionais no Brasil de Macêdo e Silva (2020). Participaram 168 docentes com a presença majoritária no gênero feminino (N=146). Os resultados apontam uma forte associação entre manter o autocontrole nas emoções e a capacidade de manter um desempenho profissional satisfatório em situações de estresse (regulação emocional). Ficou evidenciado que as variáveis: idade e estado civil são preditoras do trabalho remoto. Indicam-se novas investigações e estudos em outras culturas e regiões do país.

Esta pesquisa tem por objetivo apresentar uma proposta para o ensino de leitura e compreensão de texto a partir do conto “A moça tecelã” de Marina Colasanti. Partimos do pressuposto de que o sentido do texto é resultante de operações comunicativas e processos linguísticos sociocomunicativos, dessa forma, permite ao leitor contribuir para a tessitura do texto. Metodologicamente, a pesquisa caracteriza-se como bibliográfica, de cunho qualitativo. Para os fundamentos teóricos, o estudo foi feito com base em Solé (1998), Isola (2001), Koch (2003), dentre outros. Os resultados mostram que o trabalho com o conto pressupõe um leitor participativo que busque construir os sentidos a partir das informações implícitas presentes no texto, tendo a escola papel fundamental na formação de leitores proficientes.

Utilização de texto jornalístico para o ensino de eletricidade
Authors: Francisco Batista Heloisa Fernanda , Andrade Batista Elisson
Published: April 2024

Os conteúdos jornalísticos estão presentes no cotidiano de diversas formas e trazem conhecimentos acadêmicos de forma aplicável. A partir dessa percepção, este trabalho foi desenvolvido com estudantes do Ensino Médio de uma Escola de Educação Especial de Minas Gerais. Abordou-se a temática Eletricidade, tendo como ponto inicial uma matéria jornalística que apresentava o quantitativo de raios que caem no país e meios para que a população possa se proteger de tais descargas elétricas. Este trabalho foi desenvolvido a partir dos pressupostos de uma pesquisa qualitativa do tipo participante, no qual foram utilizados diários de campo como instrumento de controle dos dados e a análise baseou-se na Análise de Conteúdo de Bardin (2016). Em relação à utilização desse material para o desenvolvimento das aulas de Eletricidade, verificou-se que ele chama a atenção dos estudantes e possibilita maior participação, pois as notícias jornalísticas estão mais próximas de seus cotidianos e propiciam a aproximação e apropriação dos conceitos abordados.

Adaptation of humans to challenging environmental conditions, such as extreme temperature, malnutrition, or hypoxia, is an interesting phenomenon for both basic and applied research. Identification of the genetic factors contributing to human adaptation to these conditions enhances our understanding of the underlying molecular and physiological mechanisms. In our study, we analyzed the exomes of 22 high altitude mountaineers to uncover genetic variants contributing to hypoxic adaptation. To our surprise, we identified two putative loss‐of‐function variants, rs1385101139 in RTEL1 and rs1002726737 in COL6A1 in two extremely high altitude (personal record of more than 8500 m) professional climbers. Both variants can be interpreted as pathogenic according to medical geneticists' guidelines, and are linked to inherited conditions involving respiratory failure (late‐onset pulmonary fibrosis and severe Ullrich muscular dystrophy for rs1385101139 and rs1002726737, respectively). Our results suggest that a loss of gene function may act as an important factor of human adaptation, which is corroborated by previous reports in other human subjects.

High sodium intake is decisive in the incidence increase and prevalence of hypertension, which has an impact on skeletal muscle functionality. Diazoxide is an antihypertensive agent that inhibits insulin secretion and is an opener of KATP channels (adosine triphosphate sensitive potasium channels). For this reason, it is hypothesized that moderate‐intensity exercise and diazoxide improve skeletal muscle function by reducing the oxidants in hypertensive rats. Male Wistar rats were assigned into eight groups: control (CTRL), diazoxide (DZX), exercise (EX), exercise + diazoxide (EX + DZX), hypertension (HTN), hypertension + diazoxide (HTN + DZX), hypertension + exercise (HTN + EX), and hypertension + exercise + diazoxide (HTN + EX + DZX). To induce hypertension, the rats received 8% NaCl dissolved in water orally for 30 days; in the following 8 weeks, 4% NaCl was supplied to maintain the pathology. The treatment with physical exercise of moderate intensity lasted 8 weeks. The administration dose of diazoxide was 35 mg/kg intraperitoneally for 14 days. Tension recording was performed on the extensor digitorum longus and the soleus muscle. Muscle homogenates were used to measure oxidants using fluorescent probe and the activity of antioxidant systems. Diazoxide and moderate‐intensity exercise reduced oxidants and increased antioxidant defenses.
Estimating positional plus-minus in the NBA
Authors: Gong Hua , Chen Su
Published: April 2024

Plus-minus is a widely used performance metric in sports. Players with high plus-minus ratings are often considered more efficient than others. While numerous plus-minus models have emerged since the introduction of adjusted plus-minus in 2004, most of these metrics focus on evaluating player performance at the individual level. In the present study, we follow the plus-minus framework and adopt a hierarchical Bayesian linear model to estimate plus-minus at the position level in the NBA from 2015–16 to 2021–22. Results show that players with versatile offensive skills and big players who defend the paint area are the most valuable offensive and defensive contributors respectively. We also find that the gaps in offensive plus-minus between offensive position groups have decreased over time. Overall, our analysis offers valuable information regarding average positional values in the NBA, allowing more objective player comparisons within position groups. We also show improved prediction accuracy in player plus-minus when factoring in player positions.
