Simulación y análisis del sistema de transporte en el norte de la Carpetania romana. Una aproximación desde SIG y análisis de redes
Authors: Moreno Navarro Fernando
Published: July 2022

Este trabajo caracteriza el modo en que se articulaba el territorio del n de la Carpetania romana a través de sus vías de comunicación principales y secundarias. En este caso hemos enfocado este trabajo desde una perspectiva alternativa alejada de las tradicionales aproximaciones urbanocéntricas. Para ello, hemos realizado una simulación de la red de comunicaciones en el n de la Carpetania a través de Sistemas de Información Geográfica. Los resultados para las vías principales se ajustan notablemente bien con las vías descritas en las fuentes textuales antiguas. Esto nos ofrece una gran fiabilidad para poder analizar la articulación del territorio a través de las vías secundarias y caminos rurales. Mediante herramientas derivadas de los análisis de redes hemos analizado la localización de algunos de los asentamientos más característicos en la red viaria, así como las áreas con mayor accesibilidad. Estos análisis apuntan a que las aldeas y aglomeraciones presentes en el territorio jugaban un papel crucial en la articulación territorial, principalmente en aquellas áreas menos cubiertas por las áreas de influencia municipales.
¿Poblamiento y cambio social de un territorio aislado? Propuestas sobre la evolución de la ocupación territorial de la isla de Gran Canaria en época prehispánica
Authors: Moreno Benítez Marco A. , Velasco Vázquez Javier , Alberto Barroso Verónica , Delgado Darias Teresa
Published: July 2022

La colonización de las Islas Canarias ha sido objeto de diversos trabajos; sin embargo, la implantación humana en los diferentes territorios y su evolución en el tiempo es una cuestión que prácticamente no ha recibido atención en la investigación. En este trabajo presentamos una propuesta interpretativa de las dinámicas de ocupación de la isla de Gran Canaria entre los ss. III y XV d. C. desde una perspectiva temporal y comparada basada en la longue durée braudeliana. Para ello se han establecido diferentes variables –tipo de suelo, visibilidad, accesibilidad, etc.– que han sido analizadas a través de un Sistema de Información Geográfica –SIG–, tomando como unidad de observación mínima diferentes isócronas. Así, el estudio estadístico primero, y luego el análisis histórico y territorial de los yacimientos, han permitido implementar un escenario diacrónico del poblamiento aborigen de Gran Canaria, teniendo como referencia las teorías de relleno ambiental. El resultado se presenta como la interrelación de diferentes formas de utilización del territorio, tanto a nivel material como ideológico, conformándose, en consonancia, diferentes paisajes arqueológicos.
La casa imaginaria: hoyos de destoconado y desarraigo de árboles en asentamientos al aire libre de la Prehistoria Reciente
Authors: Teira-Brión Andrés
Published: July 2022

Los hoyos ocasionados por la caída de árboles son uno de los edaforrasgos más comunes en los suelos. Su origen puede ser tanto natural, la muerte y caída de un árbol, como antropogénico, relacionado con la tala del bosque. Este tipo de estructuras se han encontrado en varios yacimientos del Noroeste ibérico en las últimas décadas, pero han sido entendidas como fondos de cabaña. Además, la investigación reciente no ha tenido en cuenta las incoherencias entre sus dataciones de C14 y los eventos que supuestamente fechan. El objetivo de este trabajo es abordar los errores basados en una interpretación equivocada de los hoyos provocados por la caída de árboles y en una metodología inadecuada en la recuperación de los restos arqueobotánicos utilizados en la datación radiocarbónica. Reexaminar estos rasgos arqueológicos puede arrojar luz sobre las evidencias de deforestación y empujarnos a reconsiderar las teorías sobre la construcción de los espacios domésticos en el Noroeste ibérico.

Background and Aim: Pestivirus, a genus of the Flaviviridae family, comprises viruses that affect bovines, sheep, and pigs. Symptoms, including hemorrhagic syndromes, abortion, respiratory complications, and deadly mucosal diseases, are produced in infected animals, which cause huge economic losses to the farmers. Bovine viral diarrhea virus-1, bovine viral diarrhea virus-2, classical swine fever virus, border disease virus, Bungowannah, Hobi-like, and atypical porcine pestivirus belonging to the Pestivirus genus were selected for the study. This study aimed to estimate the codon usage bias and the rate of evolution using the glycoprotein E2 gene. Furthermore, codon usage bias analysis was performed using publicly available nucleotide sequences of the E2 gene of all seven Pestiviruses. These nucleotide sequences might elucidate the disease epidemiology and facilitate the development of designing better vaccines.

Materials and Methods: Coding sequences of the E2 gene of Pestiviruses A (n = 89), B (n = 60), C (n = 75), D (n = 10), F (n = 07), H (n = 52), and K (n = 85) were included in this study. They were analyzed using different methods to estimate the codon usage bias and evolution. In addition, the maximum likelihood and Bayesian methodologies were employed to analyze a molecular dataset of seven Pestiviruses using a complete E2 gene region.

Results: The combined analysis of codon usage bias and evolutionary rate analysis revealed that the Pestiviruses A, B, C, D, F, H, and K have a codon usage bias in which mutation and natural selection have played vital roles. Furthermore, while the effective number of codons values revealed a moderate bias, neutrality plots indicated the natural selection in A, B, F, and H Pestiviruses and mutational pressure in C, D, and K Pestiviruses. The correspondence analysis revealed that axis-1 significantly contributes to the synonymous codon usage pattern. In this study, the evolutionary rate of Pestiviruses B, H, and K was very high. The most recent common ancestors of all Pestivirus lineages are 1997, 1975, 1946, 1990, 2004, 1990, and 1990 for Pestiviruses A, B, C, D, F, H, and K, respectively. This study confirms that both mutational pressure and natural selection have played a significant role in codon usage bias and evolutionary studies.

Conclusion: This study provides insight into the codon usage bias and evolutionary lineages of pestiviruses. It is arguably the first report of such kind. The information provided by the study can be further used to elucidate the respective host adaptation strategies of the viruses. In turn, this information helps study the epidemiology and control methods of pestiviruses.
ascensão da Língua Portuguesa em São Tomé e Príncipe
Authors: Balduino Amanda Macedo , Bandeira Manuele
Published: July 2022

Este artigo discute a ascensão do português em São Tomé e Príncipe. Com base em processos históricos de interação social nos períodos colonial e pós-colonial, observou-se a difusão da língua portuguesa em detrimento das línguas locais, ainda que o input em português fosse, inicialmente, limitado. Em decorrência de pressões assimilatórias, reforçadas ao longo dos séculos XIX e XX, a população não portuguesa favoreceu o uso e a transmissão intergeracional do português, comportamento validado pelas elites locais. Após 1975, o português foi, então, consolidado, como a língua transmitida pelas gerações mais velhas, tornando-se a língua materna da maior parte da população de São Tomé e Príncipe, possibilitando, assim, a emergência de variedades singulares do português, as quais são marcadas pelo contato com as demais línguas locais.
Representações de experiências de quase morte
Authors: Milanez Aline Andrea Zamboni , Alencar André Luiz Siqueira
Published: July 2022

O objetivo deste artigo é a análise da variação das dimensões de relatos de Experiências de Quase Morte (EQM). Nas últimas décadas, diversas áreas do conhecimento têm investigado o fenômeno, desde o lançamento do livro de Moody (1975), dentre as quais a linguística. Nenhum estudo, até o presente momento, investigou sua variação de dimensões na língua inglesa, por meio da Linguística de Corpus (LC) (BERBER SARDINHA, 2004) e da Análise Multidimensional (AMD) (BIBER, 1988). Como método principal do estudo, usou-se a AMD aditiva (BIBER; CONRAD, 2001) e  AMD completa (BIBER, 1988), a fim de mapear 1223 relatos nas dimensões de variação do inglês e desvendar suas dimensões próprias. Em relação à AMD aditiva, o corpus de estudo apresentou escore positivo nas dimensões um, dois e cinco e escore negativo nas dimensões três e quatro. Quanto à AMD completa, três dimensões funcionais foram identificadas e interpretadas como (1) Discurso relatado vs. Descrição elaborada, (2) Discurso Deôntico e (3) Discurso com enfoque no posicionamento.
Cotidiano e presentificação
Authors: Gueller Viviane
Published: July 2022

Esta pesquisa aborda um conhecimento engendrado em minha prática artística a partir do encontro com interstícios da vida urbana. Trata-se da imagem-experiência, uma imagem portadora de experiência, investida por suas marcas, originada em um gesto de colocar-se em disponibilidade perceptiva. A sua instauração em espaços expositivos marcados por características históricas e cotidianas singulares motivou a reflexão sobre uma ativação mútua entre o trabalho e seu local de inscrição, proporcionando o entendimento da presentificação como uma atualização da imagem-experiência. Os estudos de Henri Lefebvre (1901-1991) sobre a vida cotidiana são fundamentais para refletir, investigar e aprofundar as implicações deste exercício poético que nasce do mundano, de situações de encontro entre brechas na vida que corre. A proposição de uma presentificação da imagem-experiência traz uma perspectiva de relação com a formulação dialética site e nonsite, de Robert Smithson (1938-1973), e também entre conceitos como habitar, de Martin Heidegger (1889-1976).

O presente ensaio tem como objetivo central analisar o ensino de geografia em tempos de hegemonia das tecnologias digitais e da forte presença da chamada educação online. Frente a essa temática envidamos esforços para responder de forma provisória e flexível as seguintes indagações: Que questões críticas se interpõem ao contexto pedagógico da geografia marcado pelo cruzamento intenso entre práticas ensino e as mídias e tecnologias digitais? Quais são as interposições desse processo no trabalho do docente de geografia? Essas questões orientadoras são analisadas tendo como referência um esboço teórico do campo da educação, das mídias digitais e do ensino de geografia. Procuramos balizar as indagações com inferências construídas no campo da pesquisa e das observações do movimento atual em torno da escola, dos processos formativos e do ensino de geografia, todos eles marcados pela vida online e pela profusão de recursos educacionais digitais.
O APELO DOS LUGARES ÀS AFECÇÕES DOLOROSAS CRÔNICAS
Authors: Carvalho Caê Garcia
Published: July 2022

Discutimos neste artigo as condições e consequências existenciais da problemática da dor crônica em pacientes que sofrem com duas enfermidades, a saber, a artrite reumatoide e a fibromialgia. A literatura antropológica e psicanalítica nos indica que a dor não advém simplesmente de um processo orgânico, físico-corporal, como tantas vezes – e ainda hoje – a medicina tenta compreendê-la. A nossa tese é que a dor, em determinados casos (sobretudo para o quadro da fibromialgia), ao mesmo tempo em que matiza um rompimento das relações com o mundo por causa das limitações físicas, é também fruto de um alijamento do ser para com o mundo, é uma tentativa, por parte do sujeito, de expurgar-se da realidade em vistas de sua nulificação quanto ao desejo de ser. Além de apresentarmos uma argumentação teórica – na esteira da psicanálise e da fenomenologia – quanto a esses processos, veremos, doravante, como os lugares podem se constituir como um ponto de reenlace da relação então abortada entre ser e mundo e como o sujeito pode recuperar-se das lamúrias de sua cronicidade. Uma recuperação se entreabre para esses pacientes na reconstituição do laço ontológico de ser-no-mundo, reascendendo, pelo lugar, o desejo de ser.

Una introducción a los problemas del medio rural contemporáneo en México
Authors: Gómez-Bonilla Adriana Petrovna , Martín Pere Sunyer
Published: July 2022

Los problemas contemporáneos del medio rural en México se resumieron durante mucho tiempo en la lucha por el acceso a la tierra. El artículo 27 de la Constitución de 1917, aprobada durante la Revolución mexicana (1910-1918), vino a paliar temporalmente esa demanda. La Reforma agraria aplicada desde los años treinta del siglo XX no consiguió sin embargo superar el problema endémico de la pobreza del mundo rural. Sesenta años después, la crisis del campo mexicano se pensó superar mediante la liberalización del mercado de tierras. A cien años de la aprobación de la Constitución revolucionaria, una nueva demanda se alza en el campo mexicano: la defensa del territorio.
Palabras clave: Artículo 27. Lucha por la tierra. Defensa del territorio. Campesinado.

Authors: Esposito Laura Fernanda Dias Ribeiro , Vieira Maria de Fátima , Martins Alex Lara , Quaresma Edson Antunes
Published: July 2022

O conjunto de ações autocráticas de um governo eleito democraticamente submeteria as instituições de ensino a processos contrários ao primado democrático. Esta pesquisa bibliográfica e documental objetivou identificar e analisar elementos autocráticos de instrumentos jurídicos publicados entre 2020 e 2021, com impacto na Rede Federal de Educação. Foram adaptados cinco indicadores de ações antidemocráticas para a área da educação, a partir dos quais os instrumentos jurídicos do governo foram analisados. Evidenciou-se, a partir desse trabalho, um conjunto de ações autocráticas do governo que colocam em risco as bases da democracia, mas também a possibilidade de resistir a elas.
Regularidades nas políticas de formação docente dos anos 1990 e atuais: o cuidado de si da Academia
Authors: Cunha Alexander Montero , Rodrigues Daniele Gualtieri
Published: July 2022

O presente trabalho envolve a busca por regularidades discursivas nas políticas da década de 1990 e atuais de formação de professores. Numa perspectiva foucaultiana, destacamos regularidades que envolvem a resistência da Academia frente à ingerência do Estado nos projetos de Cursos de Licenciaturas em ambos os períodos. Essas regularidades nos auxiliaram na composição de um cenário que não tem a pretensão de previsões futuras e sim salientar um possível conflito ético eminente que envolve o governo de si e o cuidado de si da Academia. Por regularidade, salientamos que a resistência na falta de um espaço de diálogo pode resultar na marginalização da Academia da sua função de formação de professores, o que poderia descaracterizar boa parte de sua identidade enquanto instituição.
Indicador para medir la migración de valor en pymes argentinas
Authors: Casella Volosin Guido , Martínez Mansilla Jerónimo , Rivera Motrich Santiago
Published: July 2022

Esta investigación buscó construir un indicador que mida la migración de valor y que pueda aplicarse a las PyMEs que no cuentan con información de la capitalización bursátil. Para ello, se elaboró un cuestionario que indaga sobre los factores impulsores de migración de valor agrupados en dimensiones, a ser administrado a los gerentes de PyMEs de una muestra no probabilística. El indicador de migración de valor se obtuvo por adición de las puntuaciones de las variables ordinales relevadas y se determinaron, también, contribuciones por dimensión. Aplicando la prueba no paramétrica de Mann–Whitney se identificaron las variables más significativas en la medición de la migración de valor. Los hallazgos indican que los avances tecnológicos y la vinculación de las empresas con su entorno resultan elementos fundamentales para captar valor y deben considerarse al diseñar un modelo de negocio.El índice propuesto permite salvar la limitación del indicador de Slywotzky, único indicador análogo prexistente, que solo puede ser aplicado a empresas con capitalización bursátil. Este constituye una valiosa herramienta para que las empresas midan si están perdiendo, reteniendo o ganando valor y permite obtener información para mejorar el proceso de toma de decisiones y la planificación estratégica. Además, posibilita el análisis del modelo de negocio y su ajuste en relación a las prioridades cambiantes de los clientes.
El efecto del regreso a clases presenciales durante la Pandemia del Covid–19 en los casos confirmados en Argentina
Authors: Boquete Seidán , Gomez Alonso Benjamín
Published: July 2022

En esta investigación se analiza el efecto del retorno a clases presenciales entre febrero y marzo de 2021 en Argentina en los niveles inicial, primario y secundario sobre el nivel de contagios por Covid–19 en 57 departamentos del país. La hipótesis es que las clases presenciales producen un incremento de los casos confirmados por Covid–19 desde dos frentes: por un lado, directamente dentro de las instituciones educativas. Por otro, a través del aumento en la movilidad que el traslado de los estudiantes hacia y desde las instituciones educativas produce. Para evidenciarlo, se utiliza aquí un modelo econométrico deDiferencias en Diferencias. A la vista de los resultados, no se encuentra evidencia estadísticamente significativa de que el regreso a clases presenciales haya afectado, ya sea de forma positiva o negativa, a la cantidad de casos confirmados por Covid–19 en el total de la población ni en los grupos etarios de 18 a 34 años, 35 a 59 años y 60 años en adelante entre el 2 de febrero de 2021 y el 18 de abril de 2021 en los departamentosestudiados. Por otro lado, las estimaciones del modelo indican que el regreso a clases presenciales en los niveles inicial, primario y secundario han tenido un efecto positivo y significativo de 0,58 casos en la media móvil semanal de casos confirmados por fecha de inicio de síntomas cada 100 000 habitantes de ese grupo etario luego de 30 días de haber retomado la educación presencial.
Hybrid Identity of Urban Muslim Youth: The Case of Teras Dakwah Yogyakarta
Authors: Saputra Eko
Published: July 2022

This paper describes the phenomenon of hybrid identity among young urban Muslims in the popular da'wah movement in Yogyakarta. This research takes a case study of Teras Da'wah by using an ethnographic approach. This research argues that today's da'wah movement is oriented towards market Islam or market religion. The consequence of this market Islam is that it gives birth to a distinctive da'wah movement, namely the identity of young Muslim hybrids who appreciate various Islamic ideologies. In addition, their hybrid identity also has an impact on how Teras Da'wah appreciates symbols of popular culture such as developing an office or da'wah center resembling a modern cafe, using social media and slang dictions in preaching, and using contemporary da'wah themes. It also uses music, films, futsal and hanging out culture as an instrument of da'wah. This puts da'wah in a form that fits the identity of urban Muslim youths, who are pious and modern
Konsep Pendidikan Karakter dan Adab: Pemikiran Adian Husaini
Authors: Radino Radino , Hidayat Yunus Nur
Published: July 2022

Character education in Indonesia is now experiencing a decline, thus proving that the government's efforts have not been successful in significantly improving the nation's character. So this requires the whole community, especially the leaders of Indonesian education observers to think of steps or solutions that are solutions to these problems. One of the figures who intensively gives criticism and suggestions for solutions for Indonesian education is Adian Husaini, he pays great attention to the problem of the nation's character. This study aims to describe the concept of character education from the perspective of Adian Husaini and its relevance to Islamic religious education. This research is a literature study, using the documentation method, while the data analysis uses descriptive qualitative analysis. The results of this study indicate that character education alone is not enough, character education should be balanced with adab education based on Islam which is relevant to the philosophy of the Indonesian nation which is based on the One Godhead. A curriculum based on adab cultivation and a piety curriculum is one of the alternative solutions that Adian Husaini has explained.
Effect of Explosive Shapes (in Sand Buried Condition) on the Failure of a Circular Clamped Plate of Protective Vehicle
Authors: Choudha Pankaj K. , Kumaraswamy Adepu , Rao V Venkateswara
Published: July 2022

Protective vehicles like armoured personnel carriers (APCs) require assessment of failure of structural elements subjected to impulsive load resulting from explosive blast under sand buried conditions. The explosive shape and location of detonation affect the failure in near field region. In the present study, a circular clamped Rolled Homogenous Armour (RHA) steel plate has been modelled using JC strength & damage model and explosive using JWL equation. Initially, the reflected pressure and specific impulse for a fixed quantity of explosive (3.75 kg) of various shapes i.e. sphere, hemisphere, cylinders with Length to Diameter (L/D) ratio varying from 0.1 to 1 were studied for sand buried at a standoff distance of 118.1 mm. Further, studies were extended for cylindrical charges of φ 213.77 mm with conical 120°-150° and hemispherical cavities with radius of R1.2-R1.8. It was observed that, reflected pressure and specific impulse is much higher for hemispherical cavity of R1.2. The permanent deformation obtained using non-dimensional impulse is valid for explosives without cavities. However, the cavity charges produce failure of plate in the central region of the charge. The critical impulse emerges as an important parameter for assessing failure due to cavity charges. In addition, the scale down experiment is conducted to validate the effectiveness of cavity charges. It can be concluded that cavity charge with hemispherical radius of R1.2 can provide highest damage to RHA plates in close standoff distance.
MAKING INVESTMENT DECISIONS IN AN INDUSTRIAL ENTERPRISE UNDER UNCERTAINTY
Authors:   South Ural State University, Mokhov V.G. , Chebotareva G.S.
Published: July 2022

The article is devoted to the issue of selecting investment projects for the modernization of an industrial enterprise in the conditions of uncertainty. Uncertainty in this work is understood as the lack of data on the likelihood of the implementation of scenarios of alternative investment projects. As a methodological base, a set of generally accepted quantitative criteria for reducing uncertainty is proposed, which is characterized by different attitudes towards the probability of future events (pessimistic, optimistic, neutral, etc.). Additionally, a criterion is selected that combines expert and quantitative assessment of uncertainty. Practical calculations are made according to five criteria for three scenarios of five investment projects of an industrial enterprise. The aim of this work is to assess the difficulty of making unambiguous investment decisions under conditions of uncertainty. As a result, each of the four quantitative criteria has pointed to a different project. The fifth criterion has made it possible to limit the range of choice to two projects. This has confirmed the conclusions that making investment decisions requires the responsible person to use not only quantitative indicators, but also existing experience and intuition. The reliability of the findings has been confirmed by the use of generally accepted models and methods, as well as the practical implementation of the results. It is recommended to use these results in the scientific community when conducting subsequent methodological studies aimed at reducing uncertainty, as well as to business owners and investors when making strategic decisions.
ON DETERMINING THE COEFFICIENT OF HEAT EXCHANGE IN STRATIFIED MEDIUM
Authors:   Yugra State University, Belonogov V.A.
Published: July 2022

In the article we consider the well-posedness in Sobolev spaces of the inverse problems of determining the heat exchange coefficient at the interface which is included in the transmission condition of the imperfect contact type. In a cylindrical spatial domain, a second-order parabolic equation is considered. The domain is divided into two sub-domains, on the common part of the boundary of which the transmission condition is set. The heat exchange coefficient included in the transmission condition is sought as end segment in series with time-dependent unknown Fourier coefficients. The equation is supplemented with general boundary conditions and initial conditions, as well as overdetermination conditions. The ovedetermination conditions are the values of a solution at some points lying in the spatial domain. Under natural smoothness conditions for the data and the location of the measurement points, the existence and uniqueness theorem local in time is demonstrated. The obtained solution to the problem is regular, i. e., all generalized derivatives included in the equation are summable to some power, and the equation holds almost everywhere. The method is constructive, and the approach allows to develop numerical methods for solving the problem. The proof is based on a priori estimates obtained and the fixed-point theorem.
ANALYSIS OF THE BOUNDARY VALUE PROBLEM FOR THE POISSON EQUATION
Authors:   South Ural State University, Ushakov A.L.
Published: July 2022

The mixed boundary value problem for the Poisson equation is considered in a bounded flat domain. The continuation of this problem through the boundary with the Dirichlet condition to a rectangular domain is carried out. Consideration of the continued problem in the operator form is proposed. To solve the continued problem, a method of iterative extensions is formulated in an operator form. The extended problem in operator form is considered on a finitedimensional subspace. To solve the previous problem, an iterative extension method is formulated in operator form on a finite-dimensional subspace. The continued problem is presented in matrix form. To solve the continued problem in matrix form, the method of iterative extensions in matrix form is formulated. It is shown that in the proposed versions of the method of iterative extensions, the relative errors converge in a rate that is stronger than the energy norm of the extended problem with the rate of geometric progression. The iterative parameters in these methods are selected using the minimum residual method. Conditions are indicated that are sufficient for the convergence of the applied iterative processes. An algorithm is written that implements the method of iterative extensions in matrix form. In this algorithm, the iterative parameters are automatically selected and the stopping criterion is indicated when the estimate of the required accuracy is reached. Examples of application of the method of iterative extensions for solving problems on a computer are given.

Published: July 2022

This paper evaluates the strategies applied in handling reputation and brand management of Kenya Meat Commission over the history of the corporate. A brief historical background of Kenya Meat Commission lays the foundation of the study by juxtaposing various brand and reputation management concepts and principles from desktop research. To achieve the study purpose, two specific objectives guided the researchers viz.: To analyse the branding and reputation management strategies through SWOT analysis of Kenya Meat Commission’s internal environment; and to assess the branding and reputation management strategies through PESTEL analysis of Kenya Meat Commission’s external environment. Desktop research methodology was used and empirical data from other regional countries specifically Botswana Meat Commission was used to comparatively guide critical assessment of Kenya Meat Commission. The study concluded that Kenya Meat Commission has failed over and over again due to poor branding and reputation management efforts as evidenced following the SWOT and PESTEL model analyses. The study recommends that Kenya Meat Commission should consider instituting a corporate communications department that will raise its branding and reputation management efforts and consequentially cause it to become a more profitable corporate in Kenya and beyond.
The Effectiveness of Virtual Events During Covid-19 Pandemics
Authors: Ton Han Nu Ngoc , Do Quynh Hai Xuan
Published: July 2022

Events suffer from severe impacts of COVID-19 restrictions on mass gatherings. The industry shifts to digital environment to sustain. However, virtual events’ limitation is multi-dimensional interaction resulting in consumer experience and satisfaction. Therefore, the effectiveness of virtual events is questioned. Key themes of COVID-19 impacts on the event industry and virtual event environment are review. Then, a conceptual model on event experience is applied as the theoretical framework of this research. This research is guided by the constructivism approach. Using qualitative methods and a semi-structured questionnaire, six interviews were conducted to exploit narratives on virtual event interaction and attendee experience. Data are analyzed according to three key themes of pre-, during-, and post-event experience. The incompletion of five senses in virtual event design restrains interpersonal interaction which negatively affect attendee experience. Some practices are recommended to increase virtual event’s effectiveness, including virtual avatars, three-dimensional projection, and hybrid events. Experience on virtual events is negative due to low degree of interpersonal interaction. Various application of virtual reality technology is suggested to improve effectiveness. Despite some limitations, this research has expanded the literature of virtual events.
Identifying CRAAP on the Internet: A Source Evaluation Intervention
Authors: Muis Krista Renee , Denton Courtney , Dubé Adam
Published: July 2022

Individuals of all ages struggle to determine the reliability of information on the internet. To address this common issue, many educational institutions have endorsed the CRAAP test (i.e., currency, relevance, authority, accuracy, and purpose) as an effective approach to support identification of unreliable information. The present study extended the CRAAP test by incorporating a modeling component on how to evaluate and integrate multiple sources of varying quality on the internet and evaluated the efficacy of this source evaluation training intervention. Eighty-two participants across Canada were recruited to evaluate six authentic webpages and then construct an argument on a specific topic. Half the sample received training to examine the currency, relevance, authority, accuracy, and purpose (i.e., CRAAP) of the webpages before completing the online activity. Results revealed that the intervention group provided more accurate rank-ordering of the webpages, but no differences were found between groups on source integration via an argumentative essay. These findings suggest that the CRAAP test is effective in improving individuals’ evaluations of online sources but is not effective in promoting better quality source integration.

Published: July 2022

Minimally invasive surgery is the standard for many abdominal interventions, with an increasing use of telemanipulated robots. As collaborative robots enter the field of medical interventions, their intuitive control needs to be addressed. Augmented reality can thereby support a surgeon by representing the surgical scene in a natural way. In this work, an augmented reality based robot control for laparoscopic cholecystectomy is presented. A user can interact with the virtual scene to clip the cystic duct and artery as well as to manipulate the deformable gallbladder. An evaluation was performed based on the SurgTLX and system usability scale.

Radiocarbon in Dinosaur Bones Revisited
Authors: Senter Philip J.
Published: July 2022

Evidence from isotopes other than radiocarbon shows that dinosaur fossils are millions of years old. Despite that, bone mineral from Mesozoic dinosaur fossils yields a falsely young radiocarbon “date” of less than 50,000 years, due to its accumulation of new radiocarbon via recrystallization. Similarly, the so-called collagen fraction of Mesozoic fossil bone (actually the total organic fraction) yields a falsely young “date,” due to the presence of organic contaminants, including glue that is added during fossil excavation. The contaminants are responsible for the falsely young radiocarbon “date.” That problem can be overcome by the HYP method: subjecting only the hydroxyproline (the part of the “collagen” fraction that is specific to collagen) in the “collagen” fraction to radiocarbon dating. Science educators need to be aware of the details of these phenomena, so as to be able to advise students whose acceptance of biological evolution has been challenged by young-Earth creationist arguments that are based on radiocarbon in dinosaur bone “collagen.”
Connected Despite Lockdown: The Role of Social Interactions and Social Media Use in Wellbeing
Authors: Sun Rui , Rieble Carlotta , Liu Yang , Sauter Disa
Published: July 2022

Humans are social beings, but during the COVID-19 pandemic, people around the world were periodically in lockdown and were required to try to physically distance themselves from others. The resultant limitation of face-to-face interactions presented a challenge to wellbeing. During periods of lockdown, people could, however, still connect to others via technology, but it is unknown whether such interactions offer benefits comparable to face-to-face interactions. In the present study, we examined how different ways of interacting with others impacted wellbeing during a period of lockdown in the United Kingdom. In a 30-day diary study conducted in April-June 2020, 110 adults reported the time they spent daily on face-to-face interactions and technology-mediated communication (video, phone, text) with different interaction partners. They also indicated the time they spent on active and passive social media use and their end-of-day wellbeing. Multilevel regressions indicated that more face-to-face interactions both within and outside of one’s household positively predicted wellbeing, while technology-mediated communication had less consistent positive effects. Additionally, more active and less passive social media use predicted better wellbeing. These results highlight the complexity of benefits of different kinds of social interactions during lockdowns in the COVID-19 pandemic and point to the importance of taking into account communication channels, interaction partners, and how people use social media when studying the effects of connecting to others.
Connection
Authors: Evans Keith
Published: July 2022

This essay is an autoethnographic reflection on what it means to spend a lot of life alone, most especially at Christmas, in Westernized societies a time of year in which it is unacceptable, or at least unexpected, to be alone. I explore one of the many trips to mountain shelters, known in Scotland as bothies, that I’ve made alone over the Christmas holiday. I tell how it was to walk into and climb the mountains around the bothy in a storm, and explore my own internal relationship with being alone, with Christmas, and with my broken heart.
Stepwise pluripotency transitions in mouse stem cells
Authors: Endoh Mitsuhiro , Niwa Hitoshi
Published: July 2022

Pluripotent cells in mouse embryos, which first emerge in the inner cell mass of the blastocyst, undergo gradual transition marked by changes in gene expression, developmental potential, polarity, and morphology as they develop from the pre‐implantation until post‐implantation gastrula stage. Recent studies of cultured mouse pluripotent stem cells (PSCs) have clarified the presence of intermediate pluripotent stages between the naïve pluripotent state represented by embryonic stem cells (ESCs—equivalent to the pre‐implantation epiblast) and the primed pluripotent state represented by epiblast stem cells (EpiSCs—equivalent to the late post‐implantation gastrula epiblast). In this review, we discuss these recent findings in light of our knowledge on peri‐implantation mouse development and consider the implications of these new PSCs to understand their temporal sequence and the feasibility of using them as model system for pluripotency.
Generosity as Capital to Win: Ethnic Minority Chinese and Social Capital in Belu Government Head's Election 2015, East Nusa Tenggara
Authors: Mbiri Adeo , Alfirdaus Laila Kholid
Published: July 2022

This article discusses the modalities of minority ethnic groups to win the 2015 local government head's election in the District of Belu. There were three candidates in the election, two were the local ethnic group residents, and one candidate was Chinese, generally known to be the newcomers (migrants) in Indonesia's social context. Interestingly, the candidate from a minority ethnic group succeeded in winning the election and led the district for the next five years. In addition to the fact that the candidate is from a minority ethnic group, the candidate is not known to be the richest one compared to the others. This article looks at the three candidates' social, political, and economic modalities, applying qualitative research with interviews and observations as the data collection method. Although economic and political modalities are necessary, the results reveal that social modalities remain a key factor in gaining community support. Willybrodus Lay, the local Chinese candidate, paired with Ose Luan, won the election despite not being the wealthiest candidate with the most potent economic modalities. Lay's well-known generosity, and his good relationships with the greater community, and his proximity to various social institutions, especially with churches, mosques, and traditional groups, as well as his personality, led him to win the election. He beat another candidate, known to be the richest among the three, and another one, the most popular in local bureaucracy.
