COVID-19 mortality paradox (United States vs Africa): Mass vaccination vs early treatment
Authors: Kelleni Mina Thabet
Published: March 2024

The coronavirus disease 2019 (COVID-19) mortality rate in 55 African countries is almost 4.5 times lower than in the coronavirus disease 2019 (COVID-19) despite Africa having over 4.2 times more people. This mortality paradox is also evident when comparing Nigeria, a heavily populated, poorly vaccinated and weakly mandated country to Israel, a small, highly vaccinated and strictly mandated country. Nigeria has almost 4 times lower COVID mortality than Israel. In this Field of Vision perspective, I explain how this paradox has evolved drawing upon my academic, clinical and social experience. Since April 2020, I’ve developed and been using the Egyptian immune-modulatory Kelleni’s protocol to manage COVID-19 patients including pediatric, geriatric, pregnant, immune-compromised and other individuals suffering from multiple comorbidities. It’s unfortunate that severe acute respiratory syndrome coronavirus 2 is still evolving accompanied by more deaths. However in Africa, we’ve been able to live without anxiety or mandates throughout the pandemic because we trust science and adopted early treatment using safe, and effective repurposed drugs that have saved the majority of COVID-19 patients. This article represents an African and Egyptian tale of honor.

Published: March 2024

BACKGROUND

Dysphoria and despondency are prevalent psychological issues in patients undergoing Maintenance Hemodialysis (MHD) that significantly affect their quality of life (QOL). High levels of social support can significantly improve the physical and mental well-being of patients undergoing MHD. Currently, there is limited research on how social support mediates the relationship between dysphoria, despondency, and overall QOL in patients undergoing MHD. It is imperative to investigate this mediating effect to mitigate dysphoria and despondency in patients undergoing MHD, ultimately enhancing their overall QOL.

AIM

To investigate the mediating role of social support in relationships between dysphoria, despondency, and QOL among patients undergoing MHD.

METHODS

Participants comprised 289 patients undergoing MHD, who were selected using a random sampling approach. The Social Support Rating Scale, Self-Rating Anxiety Scale, Self-Rating Depression Scale, and QOL Scale were administered. Correlation analysis was performed to examine the associations between social support, dysphoria, despondency, and QOL in patients undergoing MHD. To assess the mediating impact of social support on dysphoria, despondency, and QOL in patients undergoing MHD, a bootstrap method was applied.

RESULTS

Significant correlations among social support, dysphoria, despondency, and quality in patients undergoing MHD were observed (all P < 0.01). Dysphoria and despondency negatively correlated with social support and QOL (P < 0.01). Dysphoria and despondency had negative predictive impacts on the QOL of patients undergoing MHD (P < 0.05). The direct effect of dysphoria on QOL was statistically significant (P < 0.05). Social support mediated the relationship between dysphoria and QOL, and this mediating effect was significant (P < 0.05). Similarly, the direct effect of despondency on QOL was significant (P < 0.05). Moreover, social support played a mediating role between despondency and QOL, with a significant mediating effect (P < 0.05).

CONCLUSION

These findings suggest that social support plays a significant mediating role in the relationship between dysphoria, despondency, and QOL in patients undergoing MHD.
Image Color Balance with Laplacian and Gaussian Pyramid (CBLGP) Algorithm
Authors:   P P Savani University, Kosamba, Surat and 394125, India, Robin Hojiwala
Published: March 2024

In recent times, technology has rapidly and significantly evolved across all sectors. Digital image processing stands out as a modern technology aimed at achieving clear images. However, digitized images often encounter issues of low quality, such as unclear or underwater images that require enhancement for better visibility. These problems stem from factors like deficient focusing, lighting, and various constraints leading to low contrast, shading, and artifacts. Underwater and satellite images consistently face less-than-ideal conditions due to environmental factors like light refraction in water, particle scattering, and dust in aquatic environments. Similarly, challenges in space, such as poor illumination and lack of contrast, further complicate image analysis. Overcoming these obstacles is crucial for extracting valuable information, necessitating advanced processing techniques. This paper introduces an enhanced Gaussian/Laplace color balance-fusion algorithm designed to improve image visibility. Modifications to certain equations result in sharper and clearer images. The algorithm begins by determining the white balance of the input RGB color image and subsequently enhances its intensity. Edge improvement is carried out separately using a depth filter. The weights for each image are then determined and combined to form a Laplace Pyramid. A color restoration technique is applied to process the resulting image, producing the final enhanced image. While existing methods for image contrast enhancement typically focus on image features, they often neglect user characteristics. This paper explores the application of image sharpening, a prominent image enhancement technique, in clearing underwater or low-quality images using the proposed algorithm. Keywords: EDSHE, High pass filter, White patch ratix, Laplacian pyramid, Color restoration.

More than ever, robust, and interpretable toxic comment recognition methods are required to manage the growing frequency of toxic comments on online platforms. The research tries to incorporate techniques in Explainable Artificial Intelligence (XAI) to improve the transparency and comprehensibility of toxic comment classification. Using a comprehensive dataset, we designed a model architecture which includes the latest practices in XAI. Through rigorous experimentation, our study proves the usefulness of such methods as tools that not only increase classification accuracy but also illuminate model decision-making processes. One view is that by adding LIME and Eli5 to toxic comment classification, model performance improves both in terms of accuracy and interpretation for decisions. Our results provide valuable insights into the model's strengths and areas for refinement, contributing to the transparency and interpretability of toxic comment classification. This research contributes to the evolving landscape of interpretable machine learning, offering a pathway to more accountable and trustworthy toxic comment moderation systems.

Authors: Claar Danielle C. , Leslie Katie L. , Welicky Rachel L. , Williams Maureen A. , Wood Chelsea L.
Published: March 2024

In this module, students have the opportunity to discover the hidden world of parasites: they will come face to face with living parasites, learn about what differentiates parasites from free-living species, observe some common adaptations to a parasitic lifestyle, explore the ecological role of parasites in food webs, and assess how parasite abundance might change in a changing world. To accomplish these goals, this module includes an introductory PowerPoint presentation (including a video of parasite ecologist Dr. Chelsea L. Wood delivering this introductory lecture) and two exercises. The first exercise is a wet lab that involves dissecting an easy (and disturbing) source of live parasite material: fresh fish from your local seafood market. The second exercise is a computer lab that will allow students to engage with real data to answer the question: how do human impacts on ecosystems change the abundance of parasites in wildlife? This module will introduce students to the basics of parasite ecology and provide an opportunity to practice their data analysis and interpretation skills.

Published: March 2024

The emerging field of carbon dots (CDs), a type of carbon nanostructure that has gained significant attention due to its unique properties and potential applications. CDs possess remarkable attributes, including photoluminescence, electrochemical potential, compatibility with living organisms, solubility in water, chemical stability, and versatile surface properties. The chemical structure, particle size, and surface functionalities of CDs all have an impact on their photoluminescent properties, which are the focus of this review. The photoluminescence mechanism in CDs is discussed, highlighting their amorphous structure, and comparing them to graphene quantum dots. The paper delves into the application of CDs in artificial photosynthesis, which enhances crop growth by improving the photo-synthesis process. CDs increase sunlight and carbon dioxide absorption rates by interacting with plant leaves, potentially leading to substantial crop yield improvements. The advantages of CDs in artificial photosynthesis are explored, including their modifiable absorption characteristics across the ultraviolet to near-infrared spectrum. The paper acknowledges challenges in CD production, such as size control and aggregation, while emphasizing their potential in various fields, including sensing, bioimaging, energy devices, and catalysis. CDs' unique optical properties and versatile applications suggest a promising future for these nanostructures in numerous scientific and technological domains.

Published: March 2024

The phenomena of trance and possession are events that occur in various cultures and traditions. In general, both phenomena are characterized by the loss of control of one's body or consciousness. However, views on the causes and treatment of both phenomena may vary between Western and Islamic Psychology perspectives. This study aims to compare Western and Islamic Psychology perspectives on the phenomena of trance and possession. From the Western perspective, the phenomenon is often explained as a medical or psychological condition that can be treated with scientific methods such as drugs and psychological therapies. Whereas in Islamic Psychology, the phenomenon is explained as a manifestation of supernatural powers that affect a person's mental state. This research combines a comparative qualitative and descriptive approach by analyzing literature related to the phenomena of trance and trance from both perspectives. The results show that although there are differences in views between the two perspectives, both recognize the influence of psychological factors in the occurrence of these phenomena. In addition, Islamic Psychology recognizes the existence of supernatural powers that influence the phenomenon of trance and trance-inducing, while the Western perspective tends to reject this view. In conclusion, this study provides an understanding of the differences in views between the Western perspective and Islamic Psychology regarding the phenomena of trance and possession. It also shows that although the views between the two perspectives may differ, they can complement each other and provide a more holistic understanding of the phenomenon.

Published: March 2024

The Covid-19 pandemic has had a huge impact on the world of education. The learning process is usually carried out face-to-face, but during the Covid-19 pandemic, schools were required to follow government policies regulated by the Ministry of Education and Culture. Where the learning process is carried out in asynchronous learning, so that a teacher is highly demanded to be able to use interesting learning media, create a creative and innovative learning atmosphere so that students can understand learning material easily. Asynchronous is a learning system that is carried out delayed or indirectly, so that the teacher can only provide knowledge not in educating the student's character. However, students can easily access learning materials anytime and anywhere. This research was conducted aiming to describe the role of asynchronous in improving student achievement. This research uses quantitative methods using survey models, google forms and in-depth interviews. The results of this study indicate that student achievement will increase if these students are able to make good use of the asynchronous system in the learning process. The limitation of this study is that researchers have difficulty knowing student learning progress by using an asynchronous system in improving student achievement. Therefore, it is hoped that future researchers will be more thorough in reviewing student achievement using an asynchronous system.

Authors: Silva Tiago Rodrigues da , Silva Lucas Diogo Rodrigues da
Published: March 2024

As grandes incorporadoras brasileiras abriram capital na bolsa de valores a partir de 2007 como forma de capitar recursos para alavancagem de suas atividades. A partir deste ano o setor viveu um excelente momento devido as condições econômicas favoráveis e o alto déficit habitacional no país, podendo-se dizer que o mercado imobiliário passou um período de “euforia”. Mas a partir de 2014, este crescimento do setor, foi interrompido por uma forte crise devido a super oferta de unidades imobiliárias, e a falta de crédito bancário de clientes para aquisição de imóveis. Este trabalho teve como objetivo o estudo dos indicadores econômico financeiros de algumas incorporadoras importantes (Cyrela, Even, EZTEC, MRV e Direcional) no mercado nacional, listadas no índice setorial IMOB da Bolsa de Valores, para medir a evoluções destes indicadores durante o período de 2007 até o fim do primeiro semestre de 2017, período em que o setor da construção civil viveu dois momentos antagônicos, ou seja, forte crescimento e queda vertiginosa. Como foi mostrado nos resultados, os principais indicadores econômicos financeiros (liquidez, endividamento, rentabilidade, e giro ou atividade) tiveram um comportamento esperado para os momentos de euforia e crise.
Transtornos mentais comuns associados a acidentes e violência
Authors: Anjos Rosana Maria Paiva dos , Assis Veronica Fontes de , Alves Rebeca Santana
Published: March 2024

Os transtornos mentais comuns (TMC) são caracterizados por um conjunto de sintomas não psicóticos que afetam diretamente a rotina do paciente e contribuem significativamente para a redução da qualidade de vida do indivíduo afetado. A literatura evidencia que indivíduos com diagnóstico de TMC, são considerados de três a quatro vezes mais propensos a apresentar algum tipo de comportamento violento. Ademais, um histórico de violência física ou psicológica tem influência direta com o TMC, de forma que a violência pode ser um preditor de TMC e os problemas de saúde mental podem ser um fator de risco para se tornar vítima de violência ou, até mesmo, para se tornar o agressor. Objetivo: Analisar pessoas portadoras de TMC e a sua associação com acidentes e violências, segundo respostas registradas em Inquérito de Saúde, realizado no município de São Paulo, em 2014. Metodologia: Trata-se de um estudo observacional, transversal analítico realizado através das respostas obtidas em Inquérito de Saúde, realizada no Município de São Paulo, no ano de 2014. O arquivo foi analisado através do programa STATA, para o gerenciamento dos dados e análise estatística, sendo calculados a razão das chances e intervalos de confiança. Resultados: A um nível de significância de 5% são estatisticamente diferentes a proporção dos grupos com TMC e sem TMC, no relacionado a violência nos referentes à sequelas ou incapacidades resultantes da violência; entre as vítimas de algum tipo de violência, como insulto, humilhação, ameaça, ferimento por algum tipo de arma ou agressão física nos últimos 12 meses. Também no que se refere as vítimas de insultos, humilhações ou xingamentos nos últimos 12 meses; e entre os indivíduos que afirmaram que o(s) problema(s) de saúde decorrente(s) dessa violência limitou/limitaram suas atividades do dia a dia. Conclusão: A razão de chances de transtornos mentais comuns foi duas vezes mais alta entre as vítimas de violência, em comparação com os indivíduos que não relataram terem sofrido algum tipo de violência, essa associação pode ser explicada em razão do TMC estar correlacionado ao mais alto risco condicional de sofrer ou até mesmo provocar a violência.

This study aims to determine the relationship of living habits during the new normal period with (1) body composition and (2) blood oxygen levels after cycling while wearing a mask. This research is a multicenter study between Indonesia and Malaysia, with the data presented here being specifically from the DI Yogyakarta region in Indonesia, involving an analytical observational study using a cross-sectional approach. The study included 71 research subjects. The instruments used to collect data were fitness behavior during the pandemic (exercise frequency and duration), anthropometric and oxygen saturation measurement after cycling during pandemic. Body composition was determined using the BMI formula, involving height and weight. Oxygen saturation during cycling was measured using the Pulse Oximeter FOX-1(N) by Elitech Technovision. The largest percentage of cycling is twice a week (42.25%), followed by three, one, fifth and fourth times a week. The majority of participants cycled for 120 minutes (35.21%), followed by durations of 180 minutes, 60 minutes, 30 minutes, and so on. Oxygen saturation data shows that most subjects have oxygen saturation of 98% (47.8% of respondents), none of them have 100%, but 97% saturation, 96% occupying the second and third distributions. From the primary data obtained in Indonesia, only oxygen saturation and cycling duration showed a highly significant relationship (p = 0.009), while other variables, such as BMI and cycling frequency, did not exhibit a significant correlation. It can be concluded that a significant relationship exists between exercise duration, specifically cycling, and oxygen saturation in Indonesian subjects.
Ambassadors in Pinstripes
Authors: Zeiler Thomas W.
Published: March 2024

Inspired and led by sporting magnate Albert Goodwill Spalding, two teams of baseball players circled the globe for six months in 1888-1889 competing in such far away destinations as Australia, Sri Lanka and Egypt. These players, however, represented much more than mere pleasure-seekers. In this lively narrative, Zeiler explores the ways in which the Spalding World Baseball Tour drew on elements of cultural diplomacy to inject American values and power into the international arena. Through his chronicle of baseball history, games, and experiences, Zeiler explores expressions of imperial dreams through globalization's instruments of free enterprise, webs of modern communication and transport, cultural ordering of races and societies, and a strident nationalism that galvanized notions of American uniqueness. Spalding linked baseball to a U.S. presence overseas, viewing the world as a market ripe for the infusion of American ideas, products and energy. Through globalization during the Gilded Age, he and other Americans penetrated the globe and laid the foundation for an empire formally acquired just a decade after their tour.

Three World Cuisines
Authors: Albala Ken
Published: March 2024

The text begins with a comprehensive theory of cuisine in the introduction and moves to the parallel culinary histories of Italy, Mexico, and China: the independent domestication of crops in each, the social, political, and technological developments that gave rise to each cuisine, and cooking in both professional and home settings. It also compares the internal logic of the cooking style and techniques in a way that will resonate with students. The meat of the text compares and contrasts the three cuisines in chapters on grains and starches; vegetables; fruits and nuts; meat, poultry, and dairy products; fish and shellfish; fats and flavorings; and beverages. Readers are taken on a fascinating journey of discovery, where the background story of mis-transmission, adaptation, and evolution of cooking as it spreads around the globe with trade and immigration is revealed. It answers the big questions, such as, why did the wok prevail in China, while the sautée pan and comal were used in Italy and Mexico, respectively? Why is bread baked in the Mediterranean but more often steamed in the Far East? How are certain ingredients used in completely different ways by different cultures and why? Why is corn transformed into tortillas and tamales in one place and into polenta in another? Why do we find tomato salsa in the Americas, long-cooked sauces in Italy, and tomatoes mixed with scrambled eggs in China? Albala also challenges the notion of authenticity, providing ample evidence that cuisines are constantly evolving, adapting over time according to ingredients and cooking technologies. More than 150 of Albala’s recipes complete the instruction, inspiring readers to learn how to cook in a fundamental way.

This research aims to identify the developmental patterns of reflective learning in the health sciences context and offer suggestions for future research in this field. Our dataset consists of 385 studies conducted between 1983 and 2023 in the Web of Sciences (WOS) database. In this study, bibliometric analysis techniques such as performance analyses, co-citation analysis, co-word analysis, and co-authorship analysis were employed. The results of the co-word analysis indicated that Cluster 1 emphasizes medical education, student performance, and skill development, showcasing that self-assessment and feedback are crucial components of reflective learning. Cluster 2 explores how health services shape student experiences and the impact of reflective learning on these experiences. Cluster 3 highlights the centrality of reflective learning in professional development and patient interaction. Clusters 4 and 5 elucidate the roles of knowledge, attitudes, and quality management in the reflective learning process. Clusters 6 and 7 underscore the critical importance of continuous improvement and patient safety within the context of reflective learning. In conclusion, the topic of reflective learning is garnering increasing interest in health disciplines, and further comprehensive analyses are needed to better understand the trend of this interest.

In the last few years, the non-invasive infrared reflectography (IRR) imaging technique has been improved by means of the multispectral option both in the VIS and in the NIR range in order to achieve more reliable and accurate results. Hence, the collected data can be visualised and studied both in the spatial and in the spectral domain, being processed as reflectographic images or as punctual reflectance spectra of the materials composing the painting. This work presents the formulation and application of an easyto- use methodology to identify and map the original artist’s pigments in ancient paintings starting by a set of spectral data acquired with multispectral imaging technique in the VIS-NIR range. The preliminary results shown are obtained on a painting by Vittore Carpaccio, belonging to the collection of Gallerie dell’Accademia in Venice, Italy.

In the last years, demands on high quality products increases dramatically, e.g. in textile industry. In order to produce high functional textiles a numerous of chemical agents have to be applied to the fabrics, in several wet chemical treatments, in the production process. One auxiliary agent is the size. Sizes are colorless, water soluble substances which improve the mechanically stiffness of threads during weaving process. Usually, sizes have to be wash out of the fabric before further processing since they may affect the following production steps. Up to now, offline process control methods e.g. extraction of the size are the state of the art of process control in textile industry. It is obvious, that the time consuming and punctual analytical methods are no more seasonable for an optimal process control. Thus, alternative process control methods were on demand. This paper presents a study of the potential of NIR hyperspectral imaging for in-line analysis in textile technology. Application weights and spatial distribution of sizes on polyester fabric are investigated by NIR hyperspectral imaging. In a preliminary study a calibration to the application weight of the size was prepared and a PLS model was established. This PLS model was applied for the quantitative monitoring of the colorless size across the fabrics. Additionally, contaminants on the textile were visualized by NIR chemical imaging. Thus, NIR hyperspectral imaging is presented as a fast, precise and powerful analytical method which also fulfills the requirements of textile industry.

THz imaging for recycling of black plastics
Authors: Küter Andries , Reible Stefan , Geibig Thomas , Nüssler Dirk , Pohl Nils
Published: March 2024

This paper presents the development of a novel linecamera device in the THz-domain which is capable of measuring minute differences in broadband spectral fingerprints of nonconducting materials. The primary focus is sorting black plastics in industrial recycling contexts, where large scale sorting of different types of black plastics remains a challenge. The system operates from 84GHz to 96 GHz. As the relevant plastics exhibit no specific absorption lines in this frequency range, a broadband approach is necessary to accumulate slight differences in dielectric properties into enough entropy that a machine learning algorithm can be trained to differentiate between different materials even in the presence of contaminants such as flame retardants, color pigments and dirt. Preliminary results suggest that the blackValue® THz sensor system is capable of achieving these goals.

A racionalidade pedagógica empreendedora no direcionamento das formas de governo de si
Authors: Manfré Ademir Henrique
Published: March 2024

Este texto reflete sobre o tema Projeto de Vida, gestão de si e cultura do empreendedorismo. Objetivou analisar como o Projeto de vida – enquanto componente curricular transversal na educação escolar – alinha-se à cultura do empreendedorismo, direcionando as formas de governo de si. O Projeto de Vida, de acordo com essa cultura, promete desenvolver múltiplas dimensões, motivando os indivíduos a resolver problemas e a tomar decisões para alcançar propósitos e atingir a realização profissional. Quando associada ao Projeto de vida, essa cultura transfere os dispositivos empresariais – tais como competividade, lucratividade, desempenho e produtividade – ao âmbito educacional, subordinando os processos formativos a uma nova governamentalidade. Partiu-se do seguinte questionamento: o que temos feito de nós mesmos sob as formas de governo da vida? A partir do exposto, defende-se que o debate acadêmico sobre Projeto de Vida ancora-se em princípios provenientes do mercado neoliberal, priorizando a formação de indivíduos economicamente produtivos, porém, politicamente submissos e dóceis. Desse modo, pretende-se colocar em discussão o papel desempenhado pela racionalidade pedagógica empreendedora no direcionamento das formas de governo de si. Como forma de direcionamento analítico, a crítica foucautiana surgiu como referencial teórico capaz de apresentar criticamente os limites dos dispositivos neoliberais que inserem a Educação nas diretrizes da produtividade e da governamentalidade.
