Authors: Schmeelk Suzanna , Davis Alison , Li Qiaozheng , Shippey Caroline , Utah Michelle , Myers Annie , Reading Turchioe Meghan , Masterson Creber Ruth
Published: May 2022

Background

Mobile health (mHealth) apps have facilitated symptom monitoring of COVID-19 symptoms globally and have been used to share data with health care professionals and support disease prediction, prevention, management, diagnostics, and improvements in treatments and patient education.

Objective

The aim of this review is to evaluate the quality and functionality of COVID-19 mHealth apps that support tracking acute and long-term symptoms of COVID-19.

Methods

We systematically reviewed commercially available mHealth apps for COVID-19 symptom monitoring by searching Google Play and Apple iTunes using search terms such as “COVID-19,” “Coronavirus,” and “COVID-19 and symptoms.” All apps underwent three rounds of screening. The final apps were independently assessed using the Mobile Application Rating Scale (MARS), an informatics functionality scoring system, and the Center for Disease Control and World Health Organization symptom guidelines. The MARS is a 19-item standardized tool to evaluate the quality of mHealth apps on engagement, functionality, aesthetics, and information quality. Functionality was quantified across the following criteria: inform, instruct, record (collect, share, evaluate, and intervene), display, guide, remind or alert, and communicate. Interrater reliability between the reviewers was calculated.

Results

A total of 1017 mobile apps were reviewed, and 20 (2%) met the inclusion criteria. The majority of the 20 included apps (n=18, 90%) were designed to track acute COVID-19 symptoms, and only 2 (10%) addressed long-term symptoms. Overall, the apps scored high on quality, with an overall MARS rating of 3.89 out of 5, and the highest domain score for functionality (4.2). The most common functionality among all apps was the instruct function (n=19, 95%). The most common symptoms included in the apps for tracking were fever and dry cough (n=18, 90%), aches and pains (n=17, 85%), difficulty breathing (n=17, 85%), tiredness, sore throat, headache, loss of taste or smell (n=16, 80%), and diarrhea (n=15, 75%). Only 2 (10%) apps specifically tracked long-term symptoms of COVID-19. The top 4 rated apps overall were state-specific apps developed and deployed for public use.

Conclusions

Overall, mHealth apps designed to monitor symptoms of COVID-19 were of high quality, but the majority of apps focused almost exclusively on acute symptoms. Future apps should also incorporate monitoring long-term symptoms of COVID-19 and evidence-based educational materials; they should also include a feature that would allow patients to communicate their symptoms to specific caregivers or their own health care team. App developers should also follow updated technical and clinical guidelines from the Center for Disease Control and the World Health Organization.
Testing a Mobile App for Participatory Research to Identify Teen-Targeted Food Marketing: Mixed Methods Study (Preprint)
Authors: Truman Emily , Elliott Charlene
Published: May 2022

BACKGROUND

Mobile apps are not only effective tools for promoting health to teenagers but are also useful for engaging teenagers in participatory research on factors that influence their health. Given the impact of food marketing messages on teenagers’ food attitudes and consumption choices, it is important to develop effective methods for capturing the food advertisements targeted at this population to assess their content.

OBJECTIVE

The aim of this study was to test the feasibility and usability of a mobile app, “GrabFM!” (“Grab Food Marketing!”), designed for teenagers to facilitate monitoring of self-identified targeted food marketing messaging.

METHODS

A mixed methods approach, including quantitative user response rates and qualitative focus group discussion feedback, was used in the evaluation process.

RESULTS

A total of 62 teenagers (ages 13-17) completed GrabFM! app pilot testing over a 7-day data collection period. Teenagers submitted a total of 339 examples of food marketing, suggesting high feasibility for the app. Participants also took part in focus group discussions about their experience, providing positive feedback on usability, including ease of use and design aesthetic appeal.

CONCLUSIONS

The GrabFM! app had high feasibility and usability, suggesting its efficacy in capturing accurate data relevant to the teenage population’s experience with food marketing messaging.

Global research trends on immunotherapy in cancer: a visualization analysis (Preprint)
Authors: Weijia Wu , lei zhao
Published: May 2022

BACKGROUND

Cancer immunotherapy has been gradually introduced and has undergone noteworthy developments in recent years. The number of scientific publications has been expanding, and the progression in this field has been rapidly evolving with time.

OBJECTIVE

This study aimed to use bibliometric analysis of the published literature on immunotherapy in cancer to illustrate the research trends over the past 20 years and to summarize the hotspots for future studies.

METHODS

A literature search for medical publications on immunotherapy in cancer from 2000 to 2021 was conducted in the Web of Science Core Collection on March 1, 2022. Visualization analysis was performed using VOSviewer software (version 1.6.16).

RESULTS

From 2000 to 2021, a total of 18,778 publications were retrieved. Annual publication output grew rapidly from 366 in 2000 to 3,194 in 2021, with a clear increase in publications in 2017. The USA issued the largest number of publications (n=6,739, 35.89%), with the University of Texas System making the largest contribution (n=802, 4.27%). A total of 976 meaningful topics were identified and further classified into 4 different clusters. The most common research topics included ‘expression’, ‘chemotherapy’, ‘dendritic cells’, ‘pembrolizumab’ and ‘open-label’. Highly identified cancer types included hepatocellular, bladder, breast and lung cancer. A shift in popularity from mechanism research to clinical trials was observed, indicating that clinical application would be the center of attention in the future.

CONCLUSIONS

Attention has been given to the field of cancer immunotherapy, and this trend will continue in the future. This study provides an unbiased visualization analysis on this topic in a scale-efficient manner for further research.
Fluorescence Labelling of Proteomic Samples
Authors: Sen Srijon
Published: May 2022

Over the decades, covalent derivatization of proteins with fluorescent dyes prior to separation is widely used in the field of proteomic research. Our work examines the reactivity of a novel fluorescent dye with different proteins having different properties and check out for the reaction time of this dye with the proteins. Several experiments suggested that the reaction is increasing with time. Phosphate Buffer turned out to be a better option compared to Tris Buffer in terms of protein solubilization. Denaturing and non-denaturing gel electrophoresis suggested that the fluorescent dye reacts with Lysozyme, Bovine Serum Albumin and mammalian Red Fluorescent Protein but does not bind with Ubiquitin. Matrix assisted laser desorption/ionization-mass spectrometry also demonstrated in support of the gel electrophoresis results. The internal fluorescence property of the red fluorescent protein remained intact in the presence of this dye. This fluorescent dye can most likely be considered as a cysteine-specific dye. In many ways, fluorescence-labeling of cysteine residues presents a more attractive alternative than labeling any other residues. Serial dilution studies suggested that the sensitivity of this dye is high and can detect as low as 20 ng of BSA. Thereby, this novel fluorescent dye may serve as an alternative for labeling proteins where atleast one cysteine residue is present.

La Etnicidad en la (des) elección de escuela en Isla de Pascua
Authors: Corvalán Rodríguez Javier
Published: May 2022

This article analyzes the reasons mothers on Easter Island enroll their children in one of the three elementary schools on the island. Even though the public school offers a curriculum closer to the Rapanui language and culture than the other two subsidized private schools, a significant number of Rapanui families choose the latter two schools, which almost all non-local (continental) families also attend. Ethnicity (Rapanui and continental families) is a priority aspect for data collection and analysis in this study. After interviewing 30 mothers from both ethnic groups, including mothers of mixed families, researchers concluded that ethnicity discourse (we/they) are present in decisions to choose or avoid a school. This discourse intermingles with other social representations of the family and children’s future in a globalized world.
Aproximaciones cognitivas al estudio de la metáfora: teoría de la relevancia y teoría de la metáfora conceptual
Authors: Morgado Fernández Paula
Published: May 2022

La metáfora ha sido objeto de reflexión en diversos campos del saber. Debido a ello, no posee una clara delimitación conceptual ni tampoco un consenso respecto de cómo se comprende. En el área de la lingüística existen dos desarrollos teóricos sobresalientes para el tratamiento de este fenómeno: la teoría de la relevancia y la teoría de la metáfora conceptual. El propósito de este artículo es contrastar dichas perspectivas de estudio con el objetivo de describir sus lineamientos epistemológicos y objetivos teóricos. Los resultados demuestran que ambas propuestas integran el sustrato cognitivo en el tratamiento de la metáfora, solo que en diferente medida. La teoría de la relevancia se interesa por el proceso de generación e interpretación del enunciado metafórico, mientras que, para la teoría de la metáfora conceptual, las metáforas estructuran todo el sistema conceptual por medio del cual pensamos y actuamos.
Dimensiones de la participación política offline y online: factores de primer y segundo orden
Authors: Zumárraga-Espinosa Marcos , Reyes-Valenzuela Carlos , Carofilis-Cedeño Cynthia
Published: May 2022

El presente trabajo evalúa los modos de acción que integran las dimensiones online y offline de la participación política. Se propone que la participación política offline está compuesta por dos subdimensiones generales: la participación convencional y la protesta política. Por su parte, la participación online opera mediante una modalidad de bajo costo (soft) y otra de alto costo (hard). Los análisis de este artículo contaron con una muestra de 1 136 personas del Distrito Metropolitano de Quito, Ecuador. La estrategia para verificar las hipótesis planteadas se fundamentó en la comparación de diferentes modelos factoriales mediante análisis factorial confirmatorio. Se discute también la naturaleza multidimensional de la participación política y sus implicaciones en el contexto actual de América Latina.
El VIH en los pueblos indígenas de Oaxaca, México: de la inmunidad étnica a la vulnerabilidad estructural
Authors: Muñoz Martinez Rubén
Published: May 2022

En la actualidad no existen cifras oficiales sobre el impacto del VIH en los pueblos indígenas en México; son muy escasos los estudios al respecto, debido a la exclusión —desde ciertas ideologías dominantes— de conocer y abordar esta problemática y sus especificidades. A partir de una investigación etnográfica, complementada con análisis cuantitativo de datos epidemiológicos, se documentan y analizan  en Oaxaca (el estado que posee el mayor número de hablantes de lengua indígena): a) datos cuantitativos desagregados por etnicidad sobre prevalencia de VIH y mortalidad por SIDA; b) procesos socioculturales que producen inequidades en la prevención, detección, atención del VIH y en la mortalidad por SIDA de esta población respecto a la no indígena, y c) estrategias individuales y colectivas para afrontar las barreras en el acceso y apego al tratamiento. Se proponen las gramáticas de la inmunidad y la inmunidad étnica como eje teórico-conceptual que discute las narrativas y prácticas dominantes en la epidemiología, en la academia y en la sociedad civil respecto a esta problemática, basadas en la consideración de la etnicidad como un factor protector frente al VIH.
Aportes a la planificación de políticas públicas para un nuevo paradigma productivo
Authors: Nizza Carolina , Affranchino Gustavo , Rossen Ariana
Published: May 2022

En el presente trabajo se plantean algunos aportes para evaluar cómo incentivar una transformación sustentable de las prácticas productivas y culturales vigentes en el marco de la responsabilidad asumida por el Estado argentino frente a los Objetivos de Desarrollo Sostenible (ODS) de la Agenda 2030 de la Organización de las Naciones Unidas (ONU). Partiendo del hecho de que cada Estado adherente debe comprometerse en el corto plazo con la existencia de renovadas prácticas destinadas a la protección ambiental tanto en la sociedad civil como en el sector industrial, la dinamización de los esfuerzos en favor del logro de ello deviene en la actualidad no sólo necesaria sino también oportuna. En este sentido, aquí se expone el escenario resultante de la actual pandemia ocasionada por el coronavirus SARS-CoV-2 como una oportunidad de carácter único para comenzar a construir una nueva realidad focalizada en la sustentabilidad, destacándose la utilidad que para ello tiene la planificación de políticas públicas compatibles con tendencias productivas de vanguardia como la Economía Circular y la Industria 4.0.
Los fundamentos de “la forma nación” según Étienne Balibar: capitalismo e ideología en la modernidad
Authors: Plana Joya Genís
Published: May 2022

En un momento histórico en que las perspectivas de la globalización son sumamente inciertas, la demarcación nacional reaparece como espacio privilegiado desde el cual significar proyectos políticos orientados tanto a la izquierda como a la derecha del espectro ideológico. La contundencia con que se presenta esta realidad exige poner atención a los fundamentos que sostienen aquello que el filósofo Étienne Balibar ha denominado “la forma nación”. Con ese propósito, el presente trabajo pretende trazar un recorrido por la conceptualización que el pensador realiza de los cimientos sobre los cuales se sostiene la nación. A partir de uno de sus más célebres ensayos (La forma nación: historia e ideología), las siguientes páginas incidirán en las condiciones de posibilidad de la nación, sean éstas duras (el desarrollo de la economía capitalista a escala planetaria) o blandas (los procesos ideológicos por los cuales se configura la subjetividad nacional). En la parte final de este recorrido observaremos las consideraciones de Balibar con respecto al componente de clase que le resulta propio a cualquier comunidad nacional.

La raza y la etnia en la estratificación del mercado
Authors: Caicedo Maritza , Bermúdez Rico Rosa Emilia
Published: May 2022

En este artículo analizamos el peso de la raza y la etnia en la estructuración de las desigualdades salariales en Estados Unidos y Colombia, dos economías y sociedades disímiles con problemas comunes en el mercado de trabajo como la segregación ocupacional y la discriminación salarial. A partir de datos de la American Community Survey (2014-2018) y la Encuesta de Calidad de Vida de Colombia (DANE, 2018), ajustamos modelos de regresión lineal que nos permitieron establecer que, aunque la raza y la etnia son clasificaciones fincadas en paradigmas distintos —biológico y cultural, respectivamente—, tienen un efecto similar en el comportamiento de los salarios en los dos países, que ubica a la población afrodescendiente en abierta desventaja.

Control de convencionalidad en México: transformaciones y desafíos
Authors: Silva García Fernando
Published: May 2022

En este trabajo se evidencian las tensiones jurídicas e interpretativas que ha generado la recepción de la jurisprudencia interamericana y el control de convencionalidad entre los criterios de la SCJN, así como los desafíos que implica para los operadores jurídicos en los próximos años. A pesar de que la jurisprudencia de la SCJN ha privilegiado las restricciones constitucionales sobre las normas convencionales, lo cierto es que allí en donde no hay una restricción expresa, el operador judicial debe resolver los asuntos de su conocimiento haciendo realidad el control de convencionalidad a la luz del principio pro persona; por otro lado, en el terreno de las restricciones constitucionales expresas, la Segunda Sala de la SCJN, en sintonía con la perspectiva garantista de la Primera Sala, ha establecido que el operador jurídico debe interpretarlas de la manera más favorable a las personas.
El Parlamento y el tiempo: entre duración e instante. Perspectivas comparadas: Francia, Bélgica, Alemania, Italia, Reino Unido y Unión Europea
Authors: Cartier Emmanuel
Published: May 2022

Las democracias contemporáneas atraviesan una crisis no sólo política, sino también de temporalidad. El Parlamento aparece como centro de las contradicciones producidas por una sociedad en la que impera la velocidad y la necesidad de eficiencia, en un mundo cada vez más complejo y globalizado. El Parlamento se inscribe en el tiempo según un ritmo y una lógica especiales, de acuerdo con su identidad institucional, normativa, política y humana. Sus tres funciones clásicas (legislar, controlar el gobierno y representar) son impactadas por el tiempo y participan a la producción de un tiempo especial, entre tiempo social, político y sobre todo jurídico. Este estudio se inscribe en un marco geoconstitucional limitado a cinco sistemas parlamentarios nacionales que tienen en común un carácter bicameral y un sistema parlamentario transnacional con la UE.
El penitenciarismo mexicano del siglo XIX. Las aportaciones de Mariano Otero
Authors: García Ramírez Sergio
Published: May 2022

Este artículo revisa las ideas e iniciativas del político y jurista Mariano Otero en relación con la reforma penitenciaria planteada y parcialmente desenvuelta en el siglo XIX. Otero, bien conocido por sus aportaciones en materia constitucional y en torno al juicio de amparo (recuérdese la llamada “fórmula Otero”, incorporada en 1847), lo ha sido menos en lo que respecta a sus estudios y propuestas en materia penal y penitenciaria. El ilustre liberal jalisciense tuvo clara conciencia de la relevancia de la legislación penal dentro de las tareas del Estado y de la necesidad —siempre vigente— de renovar el sistema de prisiones y alentar el buen trato a los reclusos. Recibió la influencia de tratadistas y reformadores del siglo XVIII, como Jeremías Bentham y John Howard. En su concepto, era necesario adoptar el llamado sistema “filadélfico”, que llamó la atención en el mundo entero y atrajo a visitantes europeos, como Tocqueville y Beaumont, que deseaban conocer los avances alcanzados en los reclusorios norteamericanos.
Effectiveness of Amendment of GCC on Claims by CPWD in 2019
Authors: Gupta Nidhi , Solanki Sushil Kumar , Mittal Manoj
Published: May 2022

Abstract: Contracts are highly crucial in any sector, and we all know that claims are quite easy to make in construction projects because there are so many parties involved and each project has its own set of characteristics. In India, the majority of construction contracts are based on the GCC developed by the CPWD, and it has been discovered that due to the rigorous nature of the GCC and differences in the nature, site, and kind of projects, construction industry conflicts are highly widespread. The report aims to demonstrate the efficiency of the CPWD's revised GCC and make recommendations for reducing public contract disputes. An attempt has been made by using real-life arbitration cases and anticipating many parameters. The amended clauses have been analyzed by comparing them to the old clauses, and an assessment has been performed to determine the root reasons of the claims. To make the clauses more understandable, they've been divided into different categories, and then claims have been linked to the relevant factors in various arbitration cases.

Published: May 2022

Abstract: The project focuses on solving the problem of dust settling, stability issues of solar tracking unit and overtime decrease in efficiency of solar panels. The project is based on fabricating an automated system which can clean and track the solar panels automatically and efficiently. It works on reducing the losses caused by tracking and cleaning which could be adjusted to be fully automated as well as manually controlled as per the requirements. The major common problems in normal solar cleaning and tracking projects is the use of sensors which get affected due to adverse conditions and settling of dust due to which the mechanism provides incorrect readings. Hence these problems are solved in our project which focuses on cleaning of panels and eliminating the use of sensors like proximity sensors, etc. The project designed can be used in solar power plants and industries where timely cleaning and maintenance of Solar Panels is a necessity. Keywords: Automatic, Eliminating, Efficiency, Dust Settling, Maintenance, Tracking, Cleaning.

Fast simulation of quantum algorithms using circuit optimization
Authors: Guerreschi Gian Giacomo
Published: May 2022

Classical simulators play a major role in the development and benchmark of quantum algorithms and practically any software framework for quantum computation provides the option of running the algorithms on simulators. However, the development of quantum simulators was substantially separated from the rest of the software frameworks which, instead, focus on usability and compilation. Here, we demonstrate the advantage of co-developing and integrating simulators and compilers by proposing a specialized compiler pass to reduce the simulation time for arbitrary circuits. While the concept is broadly applicable, we present a concrete implementation based on the Intel Quantum Simulator, a high-performance distributed simulator. As part of this work, we extend its implementation with additional functionalities related to the representation of quantum states. The communication overhead is reduced by changing the order in which state amplitudes are stored in the distributed memory, a concept analogous to the distinction between local and global qubits for distributed Schroedinger-type simulators. We then implement a compiler pass to exploit the novel functionalities by introducing special instructions governing data movement as part of the quantum circuit. Those instructions target unique capabilities of simulators and have no analogue in actual quantum devices. To quantify the advantage, we compare the time required to simulate random circuits with and without our optimization. The simulation time is typically halved.

Published: May 2022

O presente artigo expõe as repercussões da pandemia do Coronavírus (COVID–19) nos processos de enunciação e subjetivação da população em situação de rua. Norteado pela pesquisa cartográfica e pela esquizoanálise, acompanhamos os movimentos da População de Rua em Parnaíba (PI), e virtualmente o Movimento Nacional da População de Rua (MNPR) durante doze meses, deslocando-se por espaços urbanos do município e redes sociais (Facebook, Instagram) e plataformas de vídeos (Youtube) do MNPR e de apoiadores, além de documentos públicos em sites do governos e Ministério Público, problematizamos os agenciamentos dos processos de subjetivação da Pop rua nesse momento de pandemia. A pandemia da Covid-19 escancarou ainda mais as vulnerabilidades vivenciadas por esse grupo e reafirmou a importância da organização coletiva das pessoas em situação de rua, exercida pelo MNPR, nesse compromisso ético-político colocando-se como meio de resistência à sujeição colonial-capitalística.
Descolonizando a Mente e o Olhar: “Xala” e a Impotência do Estado Pós-colonial
Authors: Do Nascimento Jonas
Published: May 2022

Entre as décadas de 1960 e 1970, na esteira das lutas anti-coloniais em África, vê-se surgir através do cinema a possibilidade de construção de uma identidade africana e uma autonomia cultural e política do continente. A linguagem cinematográfica configurou-se, naquele momento, numa ferramenta de discurso diante da dificuldade de escrita da História. A câmara, assim, tornou-se uma arma para a denúncia da impotência da classe política africana e, além disso, um meio para a reivindicação de uma imagem descolonizada do continente. Neste artigo, problematizo os conceitos de identidade, tradição e modernidade no contexto pós-independência africana, conforme a representação do filme Xala (1975) do cineasta-escritor senegalês Ousmane Sembène. Além disso, discuto os aspectos que possibilitaram a construção de um imaginário de superação da colonização e a articulação discursiva dessa tendência cinematográfica em torno da desejada revolução social em África.
Tema: Você é de onde?

Estes apontamentos são resultado de reflexões sobre experiências vividas por mim e minha filhas, após 14 anos nas terras brasileiras, refletidas na música de Renato Braz. Há muito por falar sobre as marcas tatuadas em nossas peles, memórias, olhos, cheiros, toques, no entanto, tentarei narrar algumas que nos marcaram e marcam como corpo que não pertence a este lugar. Experiências divididas com ela que chagara ao Brasil com apenas 6 meses de vida, onde a todo o momento tínhamos e temos que responder à pergunta: De onde vocês são? Apesar de narradas nas “primeiras pessoas”, trazem, também, à tona o que muitas e muitos de países africanos, de pele escura, vivenciam enquanto não brasileiras/os, carimbadas/os na pele e nos sotaques do não “Norte Global”. Salientar que são apontamentos sobre nossas experiências, enquanto estrangeiras não europeias e não norte americanas.
Embates ontológicos e epistemológicos com mulheres amefricanas: autonomia e independência em uma economia “informalizada”
Authors: Malomalo Bas'Ilele , Bueno Lúcia de Toledo França
Published: May 2022

O notável lugar de destaque e o papel central das mulheres nas sociedades africanas pré-coloniais tem sido inferiorizado em empreendimentos coloniais de devastação dos modos de ser africano, com desdobramentos particulares sobre as mulheres em função da instrusão da hierarquia de gênero e da consequente generificação do trabalho. A descaracterização e criminalização das organizações socioeconômicas autóctones, matrifocalizadas, expressa-se pela nomenclatura de “economias informais”. À vista disso, o presente artigo teórico-empírico tem como objetivo articular como a categoria “matriarcado” se aplica à lógica de organização socioeconômica reinventada na contemporaneidade, produzindo autonomia e independência de mulheres. Iniciamos com o embate ontológico e epistemológico que incita a resiliência das estruturas familiares e econômicas matriarcais nas Améfricas. Em seguida, na etapa empírica, constatamos as manifestações da matrifocalidade partir de relatos de lideranças de organizações econômicas e religiosas de matriz africana. Tais tecnologias econômicas matricentradas representam fonte de geração de vida individual e coletiva e – sobretudo – a capacidade de reinvenção dos princípios do matriarcado nas Améfricas contemporâneas.
A mulher e os rituais do casamento no interior de Santiago (Cabo Verde)
Authors: Silva Maria Goreti Varela Freire
Published: May 2022

Este estudo, marcadamente descritivo, foca os rituais do casamento no interior da ilha de Santiago, nos meados do século XIX, procurando compreender como é que o casamento, um ato íntimo entre duas pessoas, podia envolver duas famílias, os vizinhos ou até duas comunidades e quais as etapas percorridas desde a manifestação de interesse do jovem pretendente pela rapariga, até ao casamento. Assim, começa-se por fazer a contextualização de um casamento tradicional, arranjado e realizado, no interior de Santiago, passando pelas diferentes etapas, desde o pedido de noiva aos preparativos que antecedem o dia da cerimónia religiosa e uma série de rituais realizados na residência dos pais da noiva ao longo do dia do casamento, e à noite, antes e depois da consumação do matrimónio. Esta pesquisa bibliográfica, documental e de campo, baseada em entrevistas semiestruturadas, pretende contribuir para a descrição do casamento tradicional, recorrendo a testemunhos de figuras reconhecidas da cultura tradicional e de alguns anciãos respeitados na sua comunidade. Foi possível concluir que tanto o namoro como o casamento, nos dias que correm, são arranjados e realizados em moldes diversos e que os rituais envolventes pouco ou nenhuma relação têm com os eventos descritos no presente trabalho.
de Santiago, passando pelas diferentes etapas, desde o pedido de noiva e os preparativos que antecedem o dia da cerimónia religiosa e uma série de rituais realizados na residência dos pais da noiva ao longo do dia, do casamento, e à noite, antes e depois, da consumação do matrimónio. Este trabalho pretende contribuir para a descrição do casamento tradicional recorrendo a testemunhos de figuras reconhecidas da cultura tradicional e de alguns anciãos respeitados na sua comunidade, complementarmente, reforçados pela revisão da parca bibliografia existente sobre este assunto. Foi possível, através desta pesquisa, concluir que tanto o namoro como o casamento, nos dias que correm, são arranjados e realizados em moldes diversos e que os rituais envolventes pouco ou nenhuma relação têm com os eventos descritos neste trabalho.

Published: May 2022

Lipschütz’s ulcers (LU) are rare entities, which occur mostly in
non-sexually active young women. UL appear to be associated with
infectious conditions such as Epstein-Barr virus or cytomegalovirus. We
report a case that revealed that SARS-CoV-2 infection could be
considered a trigger event for the appearance of acute vulvar
ulceration.

Scientific Relevance and Future of Digital Immortality and Virtual Humans
Authors: Cebo Prof. Dr. Daniel
Published: May 2022

We are on the threshold of a significant change in the way we view
digital life, which will have a major effect on the physical world.
Computers have increasingly emulated deceased human beings through
growing awareness in the fields of artificial intelligence, big data,
and machine learning, and have symbolically managed to overcome death
with the help of technology. One thing is clear, though: now that there
are proper and legitimate discussions happening about human immortality,
we can be certain that the future is upon us. This article attempts to
explain and challenge the ways in which digital immortality, in
particular, has manifested itself. This paper summarizes the
technological solutions, research findings and technical challenges of
major researchers by reviewing the key technologies and general
technical schemes in the field of digital human beings. The prospects of
digital human beings are being investigated.

The focus of this paper is to critically assess the strategic importance of entrepreneurship as a mechanism for sustainable economic growth in Nigeria considering the experiences of developed nations like the America, Europe, Japan, India, and China. Entrepreneurship has been instrumental in economic growth, balanced regional development, and job creation in most dynamic economies, where technology is changing at a faster rate and the product life cycle is becoming less. Research in entrepreneurship development indicates that there is a lack of a theoretical model to examine rural entrepreneurship development particularly in the developing countries like Nigeria. The methodology adopted in this paper is the narrative – textual case study (NTCS); it is a social science research method that relies on the information and data from several sources for problem-solving. It is a fact that entrepreneurship development plays a vital role in economic development of any nation including the developing countries like Nigeria. However, despite this, most entrepreneurial policies and programs seems to favour the urban centres until recently when efforts are geared towards the rural areas. Thus, this paper examines the strategic role of entrepreneurship in the development of the rural areas in a developing economy. The study reveals that the right business environment for entrepreneurship is lacking in Nigeria on account of bad and inadequate infrastructural facilities, political instability, terrorism, multiple taxes, all stand as barriers to entrepreneurship and economic growth. The paper concludes that government should focus on adequate security, improve infrastructural facilities and enabling environment that will lead to economic growth which can be sustained to a developmental level. Keywords: Nigeria, Strategic, Entrepreneurship, Sustainable Development, Economic Growth.
Prognostication of microstructure evolution during laser powder bed fusion of aluminum alloy using phase-field method
Authors: Sahoo Seshadev
Published: May 2022

In the present study, a phase-field method-based microstructure model is developed to predict the microstructure of the AlSi10Mg alloy in the laser powder bed fusion process. For this purpose, the FORTRAN code is developed and used to solve the phase-field equations by considering different cases, i.e., without thermal fluctuation, with thermal fluctuation, and with a planar interface. From the simulation results, it is found that during rapid solidification of the AlSi10Mg alloy in the laser powder bed fusion process, a columnar equiaxed structure is formed with primary and secondary dendrites. Also, the dendritic growth velocity decreases with an increase in solidification time. The developed microstructure model will help the researchers to understand the microstructure evolution based on solidification conditions, i.e., temperature gradient, cooling rate, nuclei formation, etc. Also, the models give a fundamental understanding of the simulation procedure for the development of the new model for different alloy systems at different processing conditions.
Práctica profesional y repercusiones biopsicosociales de docentes de educación media superior por el confinamiento en Hidalgo, México
Authors: Ramírez Díaz Iliana Montserrat , Herrera Mijangos Santos Noé , Luna Reyes Dayana
Published: May 2022

El objetivo de esta investigación consistió en conocer las adaptaciones en la práctica profesional de los docentes de nivel medio superior a partir del cambio de paradigma educativo por la pandemia de covid-19 y los efectos en su salud biopsicosocial. Para lograrlo, se recurrió a una metodología cualitativa, descriptiva e interpretativa por su alcance, sustentada a partir de una entrevista a profundidad y el análisis institucional también llamado etnografía escolar. Los resultados se presentaron como una “novela” construida a partir de la narración de la participante. Se develó que el cambio de paradigma educativo representó un desafío para los docentes en diversos ámbitos, pues la implementación de la modalidad en línea generó una sobrecarga de trabajo y obligó a docentes y alumnos a adquirir los medios para continuar con las clases vía remota. La privacidad de los profesores y alumnos se vio expuesta al convertir sus hogares en las nuevas aulas escolares y surgió el temor a ser objeto de burla. Los resultados también mostraron la presencia o el agravamiento de diversos padecimientos biopsicosociales: dolores en la zona lumbar, problemas de sueño, estrés excesivo y agotamiento mental. Esta investigación puede ser considerada como una muestra de lo que han vivido otros integrantes del magisterio en México y el mundo.
Rise of Medicalised Mindfulness During the 1970s and 1980s
Authors: Morris Stephen
Published: May 2022

In the 1970s, scientists combined spiritual meditation methods with scientific knowledge to access the curative potential of belief-based practices. Mindfulness was one of several meditation methods scientists claimed could deliver health benefits. In 1979, Jon Kabat-Zinn redefined traditional mindfulness meditation for clinical use, later rebranding the training as mindfulness-based stress reduction (MBSR). Mindfulness eventually became the dominant object of meditation research, spawning a family of mindfulness-based interventions (MBIs). Today MBIs are embedded within UK health and social policy. However, despite the widespread acceptance of mindfulness, scientists have identified limitations in the evidence supporting its proliferation. Notwithstanding these concerns, little is known about how meditation converged with science during the 1970s and 1980s. Transdisciplinary investigation of the history of meditation has shed new light on mindfulness’s migration to medico-scientific domains. From this perspective, MBSR appears as part of a wider movement to relocate spiritual meditation within science. By analysing peer-reviewed scientific and humanities studies, this paper will outline how mindfulness became scientifically validated through a process I describe as medicalisation. I will also briefly discuss a possible relationship between medicalisation and current concerns in mindfulness research.

Cuando la belleza es la ciudad: áreas naturales protegidas en Río de Janeiro
Authors:   Profesora de Sociología, Programa de Pos-Graduação em Ciências Sociais, Universidade Federal Rural do Rio de Janeiro, Fraga Fernandez Annelise Caetano
Published: May 2022

Este artículo analiza la creación e implantación de dos áreas naturales protegidas (ANP) en la ciudad de Río de Janeiro. Se demuestra cómo ello pone de manifiesto, a la vez, tanto las disparidades sociales en el proceso de evolución urbana como las posibilidades para construir el derecho a la ciudad y al entorno en tanto que bien común. Los resultados de este proceso están supeditados a la equiparación de los objetivos principales (a menudo conflictivos) de las áreas protegidas: la conservación de la naturaleza, el uso público y los derechos territoriales de las comunidades locales. Partiendo de una revisión de bibliografía sobre las relaciones entre la ciudad y la naturaleza, se presentan las dicotomías y complementariedades entre ambos términos y los criterios de clasificación y denominación, de los que se han derivado distintas representaciones sociales, dispositivos técnicos y efectos políticos respecto a las ANP urbanas.
