Studies on knowledge and attitudes about HIV pre-exposure prophylaxis (PrEP) have mostly focused on key populations in North America and Europe. To inform Lesotho’s national rollout of PrEP to the general population, this study aimed to characterize knowledge and attitudes about PrEP among policy makers, implementing partners, healthcare providers, and PrEP end-users in Lesotho. Respondents were purposively selected to participate based on personal experience in the development and implementation of Lesotho’s PrEP program, or the personal use of PrEP. We conducted 106 in-depth interviews with policy makers (n = 5), implementing partners (n = 4), and end-users (current PrEP users = 55; former PrEP users = 36; and PrEP “decliners” = 6). In addition, we held 11 focus group discussions (FGDs) with a total of 105 healthcare providers. Interview and FGD transcripts were analyzed following the tenets of Grounded Theory. Respondents expressed positive attitudes toward PrEP, owing to experienced and perceived personal, familial, and societal benefits. PrEP was viewed as i) an opportunity for serodiscordant couples to remain together, ii) a means of conceiving children with minimized risk of HIV infection, iii) providing a sense of agency and control, and iv) an avenue for addressing the HIV epidemic in Lesotho. Respondents demonstrated understanding of PrEP’s intended use, eligibility requirements, and modality of use. However, respondents also reported that several important misconceptions of PrEP were common among adults in Lesotho, including a belief that PrEP protects against sexually transmitted infections other than HIV, promotes promiscuity, prevents pregnancy, causes seroconversion, and provides lifelong protection from taking the pill just once. In addition to building on the perceived advantages of PrEP to shape a positive message, Lesotho’s national rollout of PrEP will likely benefit from a communication strategy that specifically addresses the common misconceptions of PrEP identified in this study.
Reconstructing long-term dengue virus immunity in French Polynesia

Published: October 2022

Background

Understanding the underlying risk of infection by dengue virus from surveillance systems is complicated due to the complex nature of the disease. In particular, the probability of becoming severely sick is driven by serotype-specific infection histories as well as age; however, this has rarely been quantified. Island communities that have periodic outbreaks dominated by single serotypes provide an opportunity to disentangle the competing role of serotype, age and changes in surveillance systems in characterising disease risk.

Methodology

We develop mathematical models to analyse 35 years of dengue surveillance (1979–2014) and seroprevalence studies from French Polynesia. We estimate the annual force of infection, serotype-specific reporting probabilities and changes in surveillance capabilities using the annual age and serotype-specific distribution of dengue.

Principal findings

Eight dengue epidemics occurred between 1979 and 2014, with reporting probabilities for DENV-1 primary infections increasing from 3% to 5%. The reporting probability for DENV-1 secondary infections was 3.6 times that for primary infections. We also observed heterogeneity in reporting probabilities by serotype, with DENV-3 having the highest probability of being detected. Reporting probabilities declined with age after 14 y.o. Between 1979 and 2014, the proportion never infected declined from 70% to 23% while the proportion infected at least twice increased from 4.5% to 45%. By 2014, almost half of the population had acquired heterotypic immunity. The probability of an epidemic increased sharply with the estimated fraction of susceptibles among children.

Conclusion/Significance

By analysing 35 years of dengue data in French Polynesia, we characterised key factors affecting the dissemination profile and reporting of dengue cases in an epidemiological context simplified by mono-serotypic circulation. Our analysis provides key estimates that can inform the study of dengue in more complex settings where the co-circulation of multiple serotypes can greatly complicate inference.
Calcification traits for cryptic species identification: Insights into coralline biomineralization
Authors: Basso Daniela , Piazza Giulia , Bracchi Valentina Alice
Published: October 2022

Calcareous red algae are foundation species and ecosystem engineers with a global distribution. The principles governing their calcification pathways are still debated and the morphological characters are frequently unreliable for species segregation, as shown by molecular genetics. The recent description of the new species Lithophyllum pseudoracemus, previously undetected and morphologically confused with Lithophyllum racemus, offered a challenging opportunity to test the effectiveness of microanatomy and ultrastructural calcification traits as tools for the identification of these two species, for integrative taxonomy. High resolution SEM images of molecularly identified samples showed that the different size of the perithallial cells and the features of the asexual conceptacle chambers may contribute to the separation of the two species. The two species share the same crystallite morphology in the primary and secondary cell-wall calcification, as previously described in other species belonging to the same clade. However, the perithallial secondary calcification was significantly thicker in L. racemus than in L. pseudoracemus. We described a granular calcified layer in the innermost part of the cell wall, as a putative precursor phase in the biomineralization and formation of the secondary calcification. The hypothesis of different pathways for the formation of the primary and secondary calcification is supported by the observed cell elongation associated with thicker and higher Mg/Ca primary calcification, the inverse correlation of primary and secondary calcification thickness, and the absence of primary calcification in the newly formed wall cutting off an epithallial cell from the meristem.

Published: October 2022

The recent era has witnessed exponential growth in the production of multimedia data which initiates exploration and expansion of certain domains that will have an overwhelming impact on human society in near future. One of the domains explored in this article is content-based image retrieval (CBIR), in which images are mostly encoded using hand-crafted approaches that employ different descriptors and their fusions. Although utilization of these approaches has yielded outstanding results, their performance in terms of a semantic gap, computational cost, and appropriate fusion based on problem domain is still debatable. In this article, a novel CBIR method is proposed which is based on the transfer learning-based visual geometry group (VGG-19) method, genetic algorithm (GA), and extreme learning machine (ELM) classifier. In the proposed method, instead of using hand-crafted features extraction approaches, features are extracted automatically using a transfer learning-based VGG-19 model to consider both local and global information of an image for robust image retrieval. As deep features are of high dimension, the proposed method reduces the computational expense by passing the extracted features through GA which returns a reduced set of optimal features. For image classification, an extreme learning machine classifier is incorporated which is much simpler in terms of parameter tuning and learning time as compared to other traditional classifiers. The performance of the proposed method is evaluated on five datasets which highlight the better performance in terms of evaluation metrics as compared with the state-of-the-art image retrieval methods. Its statistical analysis through a nonparametric Wilcoxon matched-pairs signed-rank test also exhibits significant performance.

Published: October 2022

Cyanobacteria are prokaryotic Gram-negative organisms prevalent in nearly all habitats. A detailed proteomics study of Cyanobacteria has not been conducted despite extensive study of their genome sequences. Therefore, we conducted a proteome-wide analysis of the Cyanobacteria proteome and found Calothrix desertica as the largest (680331.825 kDa) and Candidatus synechococcus spongiarum as the smallest (42726.77 kDa) proteome of the cyanobacterial kingdom. A Cyanobacterial proteome encodes 312.018 amino acids per protein, with a molecular weight of 182173.1324 kDa per proteome. The isoelectric point (pI) of the Cyanobacterial proteome ranges from 2.13 to 13.32. It was found that the Cyanobacterial proteome encodes a greater number of acidic-pI proteins, and their average pI is 6.437. The proteins with higher pI are likely to contain repetitive amino acids. A virtual 2D map of Cyanobacterial proteome showed a bimodal distribution of molecular weight and pI. Several proteins within the Cyanobacterial proteome were found to encode Selenocysteine (Sec) amino acid, while Pyrrolysine amino acids were not detected. The study can enable us to generate a high-resolution cell map to monitor proteomic dynamics. Through this computational analysis, we can gain a better understanding of the bias in codon usage by analyzing the amino acid composition of the Cyanobacterial proteome.
"Cordons, vírgules i anguiles" en la ciudad. Sátiras y respuestas políticas en torno a la epidemia de cólera de 1885 en Valencia
Authors: Ramón Ros Jorge
Published: October 2022

Mientras el cólera se introducía en 1885 en las rutinas comerciales y sociales de Valencia, publicaciones satíricas en ascenso como La Moma y La Traca intentaban ampliar su radio de acción a través del análisis jocoso de la ciudad y sus problemas. Al principio, el humor se alimentaba de una burla de la enfermedad. Pero poco a poco, se convirtió en un medio maleable de dar sentido a la epidemia y criticar el ejercicio político de las autoridades municipales y estatales, en este caso desde sensibilidades cercanas al republicanismo. Asimismo, en las "sátiras coléricas" confluían preocupaciones que superarían la coyuntura epidémica, mostrando una ciudad cuyo gobierno y su turno dinástico estaba deslegitimado. La desigualdad social, reforzada por diferentes exposiciones y comportamientos ante la enfermedad, la falta de infraestructuras sanitarias o la imbricación con el entorno agrícola próximo eran crecientemente problematizadas en vistas a hipotéticos desarrollos urbanos futuros.
La trascendencia de la nación y de la persona: lo heroico, lo post-heroico y sus narrativas modernas
Authors: Beriain Josetxo , Gil Gimeno Javier
Published: October 2022

El presente trabajo tiene por objeto llevar a cabo un análisis de dos narrativas presentes en las sociedades actuales: la heroica-nacional y la post-heroica, que nos ofrecen una certera medida del carácter sacralizador o re-sacralizador de las sociedades modernas y seculares. Para llevar a cabo esta tarea, en un primer momento, estableceremos las bases conceptuales sobre las que se articulan los procesos de sacralización moderna, para lo que utilizaremos los conceptos de trascendencia y religiosidad en los trabajos de autores tan significativos como Georg Simmel, Émile Durkheim, Alfred Schütz y Thomas Luckmann o Max Weber. Una vez realizada esta labor, y en un segundo momento, presentamos dos de las sacralizaciones más importantes vinculadas a la «Era Secular»: las que se articulan alrededor de la nación y de la persona. De este modo, a partir de ellas y en un tercer paso, llevaremos a cabo un análisis en profundidad de las dos narrativas señaladas anteriormente, llegando a la conclusión de que las mismas conviven en la actualidad en un estado de tensión dinámica, actuando como claros símbolos de la vitalidad religioso-secular y de la gran heterogeneidad de fórmulas de sacralización que alberga esta época.
La mirada del refugiado colombiano a partir del análisis de Parábola del retorno (Juan Soto, 2016, Colombia)
Authors: Marcos Ramos María , Calvo de Castro Pablo
Published: October 2022

El presente artículo analiza el documental Parábola del retorno, realizado por el director colombiano residente en Londres Juan Soto (2016), para reflexionar sobre cómo el cine puede ser una herramienta más para hablar de los conflictos. El protagonista de la trama huye de la violencia política y de la guerra de Colombia, por lo que la historia se centra en la rememoración de la vida de este en el exilio, en mostrar visualmente el retorno y en exponer el anhelo de lo que pudo ser y no fue. El artículo se enmarca en el campo de los estudios culturales y utiliza una metodología cualitativa a partir del análisis histórico y contextual, así como del uso del decoupage aplicado a la idiosincrasia del cine documental. El director explora en su obra la representación de la ausencia, del destiempo, del destierro y, por extensión, de la identidad. El documental, a partir del uso del lenguaje audiovisual, hace reflexionar al espectador sobre estos temas y se convierte en una aproximación a la memoria histórica de un país y de una sociedad que, tras más de 60 años de guerra, afronta el reto de construir memoria sin olvidar a las víctimas en medio de un frágil proceso de paz.
Construyendo relatos sobre procesos migratorios desde prácticas artísticas colaborativas: la experiencia de cuatro mujeres artistas
Authors: Maiztegui-Oñate Concepcion , Esesumaga Salsidua Eztizen , Gandarias Goikoetxea Itziar
Published: October 2022

Son numerosas las investigaciones sobre el papel que desempeñan los y las artistas para suscitar el diálogo en torno a los problemas sociales contemporáneos y en la configuración de la forma en que vemos, pensamos y actuamos. En este artículo nos acercamos a las experiencias de cuatro mujeres artistas, todas residentes en Bizkaia —Saray Pérez Castilla, Mirian Isasi, Olga Ruiz y Argenis Mesa— cuya obra audiovisual ha reflejado el encuentro con la inmigración y el refugio. A través de una selección de sus proyectos basados en prácticas artísticas colaborativas, analizamos sus experiencias y los elementos más significativos. El análisis muestra que el proceso colaborativo se caracteriza por cinco elementos complementarios: el propio proceso, la flexibilidad y apertura, el ejercicio de la escucha, la reciprocidad o impacto mutuo y la ocupación y presencia del espacio público. Los registros gráficos de estos procesos constituyen un recurso privilegiado para reconocer relatos alternativos.
Alternativas a la migración, colaboración y post-migración: Origen de Maribel Sánchez-Maroto y Ana Pastor (2020) y No nacimos refugiados (2020) de Claudio Zulián
Authors: Ballesteros Isolina
Published: October 2022

Las representaciones mediáticas y productos audiovisuales sobre migración a menudo simplifican el fenómeno al presentarlo exclusivamente como una salida a la falta de oportunidades o a la persecución en los países emisores, o al subrayar la anonimidad, precariedad y victimización que inmigrantes y refugiados sufren en los países receptores. Dos productos culturales que tratan de aportar una visión más compleja son los que se analizan en este texto: Origen, de Maribel Sánchez Maroto y Ana Pastor (2020), y No nacimos refugiados, de Claudio Zulián (2020), desafían los mitos de la migración a Europa, alentando el emprendimiento nacional en los países de origen, y rehuyendo las connotaciones negativas asociadas a la noción de refugio. Este ensayo examina el enfoque testimonial y colaborativo de ambos documentales, así como su intención de generar «impacto» y subrayar la experiencia contra-migratoria o la «condición post-migrante» de sus protagonistas.
De identidades ciudadanas y postnacionales. Jürgen Habermas y la racionalidad identitaria
Authors: Rodríguez Fouz Marta
Published: October 2022

La identidad constituye una de las cuestiones centrales de la reflexión política y teórica de Jürgen Habermas. Su interés por ella se concentra en la configuración de un nosotros y, en mucha menor medida, en la individualidad de cada sujeto, que, en todo caso, es referida desde las interacciones que lo conforman. La atención a la identidad permite acercarse al pensamiento de Habermas desde su preocupación por la construcción de una identidad europea y por las dificultades para incorporarla como identidad postnacional. La pretensión de formular una ciudadanía europea se asienta sobre una concepción singular del patriotismo constitucional. Su orientación hacia un universalismo moral encuentra en el derecho internacional su expresión normativa más ajustada, desde donde mide las posibilidades de la racionalidad comunicativa para la materialización de identidades que estarían siempre en proceso y abiertas al cambio.

Essa revisão tem como objetivo analisar as diferentes opções em sistemas de integração lavoura, pecuária e floresta, englobando os sistemas silvipastoril, silviagrícola, agropastoril e agrossilvipastoril de forma a apontar suas características produtivas e ambientais. Atualmente diversas atividades são responsáveis pela liberação de gases prejudiciais na atmosfera, incluindo a produção agropecuária, como alternativa para a redução das emissões existem os sistemas de integração, eles se apresentam como uma alternativa que visa tornar o sistema de produção mais sustentável e reduzir os seus efeitos negativos. Esses sistemas melhoram a eficiência no uso do solo e proporcionando uma diversificação da produção por área. O sistema silvipastoril consiste na junção entre pecuária e floresta, sendo amplamente utilizado em regiões que apresentam degradação das pastagens visto que as árvores auxiliam na preservação do solo. O sistema silviagrícola consiste em unir a lavoura com a silvicultura, objetivando a diversificação de áreas nas quais ocorria apenas a produção de grãos. O sistema de agropastoril consiste na utilização de uma mesma área para o plantio de culturas e a criação de gado, proporcionando a recuperação de pastagens degradadas, a melhoria das condições físicas e biológicas do solo e grãos para alimentação animal. O sistema agrossilvipastoril engloba todas as áreas de produção disponíveis na integração, unindo de forma estratégica a lavoura, pecuária e a floresta. Os sistemas de integração proporcionam ganhos produtivos consideráveis com baixo impacto sobre o meio ambiente no qual estão inseridos, auxiliando nas boas condições do solo e na sustentabilidade ambiental.

Published: October 2022

Durante o ensino médio os alunos são apresentados a mecânica newtoniana, contudo muitas situações são simplificadas, como por exemplo, a desconsideração da força de arrasto. Essas simplificações, no entanto, quando feitas de forma inadequada podem prejudicar o aprendizado, reforçando conceitos errôneos. A fim de viabilizar a aprendizagem significativa sobre a força de arrasto, elaborou-se uma simulação acerca do fenômeno da queda livre, utilizando a linguagem de programação Python, e sua biblioteca gráfica, Vpython. Os resultados da aplicação remota da sequência didática (SD) embasada na teoria da aprendizagem significativa de Ausubel, apresenta evidências da contribuição positiva do Python no processo de ensino e aprendizagem dos conhecimentos do estudo do movimento, em particular para ensinar força de arrasto.
“The most seen I have ever felt”: Labour-Based Grading as a pedagogical practice of care:
Authors:   TE HERENGA WAKA-VICTORIA UNIVERSITY OF WELLINGTON, Gibson Lorena , Otsuki Grant , Anderson Jordan
Published: October 2022

This paper discusses experiments with Labour-Based Grading (LBG) in undergraduate anthropology courses at Te Herenga Waka—Victoria University of Wellington. Since before the COVID-19 pandemic, we have been aware that our teaching was not serving students, especially those from different class backgrounds and historically marginalized communities, and those with learning disabilities or mental health issues. The challenges these students face are compounded by a secondary school education that does not adequately prepare them for university, leaving many feeling uncared for in the classroom. In response, we developed pedagogical practices of care using LBG. We discuss LBG as an assessment method that determines students’ grades based on the time and effort they spend on an assignment, instead of more conventional subjective criteria. We reflect on staff and student experiences with LBG to offer it as a model for a future of learning that actualizes care in the classroom.
Learning with labyrinths: Neurodivergent journeying towards new concepts of care and creative pedagogy through participatory community autism research
Authors:   University of Kent, Shaughnessy Nicola
Published: October 2022

This paper arises from a UK research project, Playing A/Part, which explores the identities and experiences of autistic girls through creative practices and the implications for pedagogy. Funded by the Arts and Humanities Research Council, the project was an interdisciplinary collaboration using mixed-measures and a creative and participatory approach to co-produce new knowledge about this under-represented group. The research engaged 77 girls, aged 11 to 16, in a range of educational settings: Special Educational Needs, mainstream, and selective. The focus of discussion is the emergence of the labyrinth as a creative tool for learning and well- being and the implications for care and learning in neurodivergent contexts. After contextualising the study in relation to research on autism and gender, the paper explains how labyrinths offered an appropriate ethical, aesthetic, and sensory space for the creative pedagogic practices within the research programme. The paper also considers the implications of the study for higher education in terms of teaching neurodivergent learners, and research approaches to autism.

Modelo en gerencia de proyectos para pymes de consultoría informática en Bogotá, basado en marcos ágiles de trabajo
Authors: Arias Battle Yeraldin , Roa Rodríguez Guillermo
Published: October 2022

Contexto: Las pymes, en general, cumplen un papel muy importante en la economía y en la generación de empleo para Colombia, como país en desarrollo. Particularmente inmersas en este gran conjunto de empresas se encuentran las pymes de consultoría informática, las cuales, dentro de las empresas asociadas al área de tecnologías de información, generaron las mayores ventas del sector para 2015 (Ministerio de las Tecnologías de la Información y las Comunicaciones de Colombia [MinTIC], 2015). Sin embargo, a pesar de su gran representación y crecimiento, uno de los principales factores que inciden en sus problemáticas son los métodos de gestión de proyectos utilizados; de hecho, autores como Silveira y Silva (2015) indican la creciente tendencia y necesidad de la adaptación de marcos ágiles en las empresas. Así mismo, Whitney y Daniels (2013) refuerzan la idea del potencial de la adopción de estas metodologías en proyectos de tecnologías de información (TI), debido a su flexibilidad ante situaciones cambiantes y maleabilidad frente a controles formales.
Método: Como metodología se planteó la caracterización y definición de los aspectos críticos comunes sobre los proyectos gestionados del sector de consultoría informática, lo cual permitió continuar con la correlación de los aspectos críticos comunes identificados con marcos ágiles en gerencia de proyectos para así, usando la información obtenida, diseñar un modelo ágil en gerencia de proyectos para pymes de consultoría informática en Bogotá, finalizando con su respectiva validación.
Resultados: Se diseñó y valido el modelo para pymes de consultoría informática en Bogotá, sobre un proyecto desarrollado por una de las empresas de la muestra representativa, que cumplía con las características del estudio, sobre el cual se observó un porcentaje de mejora del 77 %, en el tiempo de entrega, del 57 % en la gestión de costo sin afectaciones a su alcance, en cumplimiento con lo requerido por el cliente.
Conclusiones: Tomando como base los resultados obtenidos al implementar el modelo desarrollado, se infiere que, al implementar el modelo en los proyectos desarrollados por empresas de consultoría informática en Bogotá (Colombia), pueden llegar a tener resultados satisfactorios en el desarrollo de sus proyectos, en cuanto al tiempo, costo y alcance, pues la validación permitió observar una mejora del 77 % en cuanto a las desviaciones de tiempo y un 57 % respecto a las desviaciones de costo precisando una mínima afectación al cumplimiento de los alcances comprometidos.
Evaluación de dos tipos de adsorbentes para la recuperación de vapores de hidrocarburos generados en Plantel de Recope en Ochomogo
Authors: Quesada Carvajal Laura Vanessa , Amón Pérez Rafael Isaac
Published: October 2022

Contexto: Al cargar el producto en los camiones cisterna, se generan vapores de hidrocarburos emitidos sin tratamiento al medio ambiente. Para evitar estas emisiones, se requiere un sistema que permita retener y recuperar estas sustancias, mediante el uso de un adsorbente capaz de retener los compuestos orgánicos volátiles generados en el patio de carga del plantel de distribución de combustibles en El Alto de Ochomogo, Cartago, Costa Rica.
Método: Se analizó la composición de los vapores desplazados durante la carga de producto limpio, y se comparó la efectividad de remoción y recuperación de dos matrices de adsorbentes: Tenax® TA y Carbotrap® 317, al modificar el método estándar TO 17 de la Agencia de Protección Ambiental de Estados Unidos.
Resultados: Con Tenax® TA se consiguió un 93,8 % de remoción; sin embargo, la mayoría de los compuestos atrapados estaban constituidos por cadenas superiores o iguales a siete átomos de carbono. Los tubos empacados con Carbotrap® 317 removieron un 99,9% de los compuestos de la muestra, reteniendo los compuestos con cadenas inferiores a los siete átomos de carbono de los vapores de gasolina. Las condiciones de acondicionamiento, atrapamiento y desorción del método modificado permitieron al Carbotrap® 317 retener y recuperar exitosamente compuestos similares a los que se están perdiendo durante la carga de los camiones cisterna.
Conclusiones: Las condiciones de acondicionamiento, muestreo y desorción del método modificado permitieron a la matriz Carbotrap® 317 retener y recuperar exitosamente compuestos similares a los que se están perdiendo durante el llenado de los camiones cisterna.

Stratagems and the Byzantine culture of war: the theory of military trickery and ethics in Byzantium (c. 900–1204)
Authors: Chatzelis Georgios
Published: October 2022

Although there has been significant scholarly attention on just war (jus ad bellum) in Byzantium and an increasing interest in the study of the Byzantine culture of war, military trickery and jus in bello (just conduct of war) remain largely unexplored by Byzantinists. This paper aims to fill this gap by studying the theory of military trickery and ethics in Byzantium, c. 900 -1204. It explores and analyses this aspect of jus in bello in Byzantium by employing methods and concepts from Byzantine history, war studies and military ethics. The paper begins by examining the impact of dominant literary traditions (Classical and Biblical) on Byzantine perceptions of military trickery, and then explores the reception and development of Classical and Biblical notions of military trickery and ethics by different sub-cultures in Byzantium (e. g., theologians, jurists, tacticians, historians, orators, poets). The author then attempts to frame a more complete theory of Byzantine military trickery and ethics, and to reflect on the relationship between jus ad bellum and jus in bello in Byzantium.
Performance, ceremonial and power in the basilikoi logoi by Theophylact of Ohrid
Authors: Medeiros Publio Dias João Vicente de
Published: October 2022

In this article, we analyse two basilikoi logoi by Theophylact of Ohrid addressed to the emperors Constantine Doukas (1081-1091?) and Alexios I Komnenos (1081-1118) and contest recent scholarship which traces criticism to Alexios I by the use of subversion of traditional rhetorical topoi. We do not question the presence of such subversions, but rather their function in the text. For that, they are studied in their performative contexts: ceremonial events, performative practices and the political circumstances in which their composition possibly took place and when they were performed. By doing so, it is noticeable that criticism to the emperor in such situations is hardly conceivable and the inadequacies of the praises present in the texts can be interpreted as a response to already existing criticism to current imperial policy. Moreover, by comparing both orations as autonomous works, it is possible to perceive a clear shift both in the power balances in the recently established Komnenian consortium and in the relationship between Theophylact and major political player of his time
The economy of Melitene/Malaṭya and its role in the Byzantine-Islamic trade (seventh to eleventh centuries)
Authors: Durak Koray
Published: October 2022

The city of Melitene in eastern Asia Minor/western Armenia presents a peculiar case in the study of Byzantine-Islamic commerce in the early Middle Ages, because, unlike Trebizond or Attaleia, its commerce was entirely based on land-route connections, and the available evidence does not identify it as a town deliberately designated as a commercial exchange point by the Byzantine authorities. My purpose is to find an answer to the question of how Byzantine- Islamic trade took place in a location on the eastern land frontier where the coexistence of war and trade was a daily reality. The products and export items as well as the routes of the Melitene zone and its neighboring regions (Cappadocia, Pontos, Armenia) are examined in order to situate Melitene in a larger commercial context. I argue that Melitene prospered commercially in the middle of war zone for centuries and that its commercial fortunes began to improve especially by the beginning of the tenth century, reaching their climax in the eleventh century.
Ein tödliches Kinderspiel und seine prognostische Bewältigung. Zu Proc. Bella 5(1).20, 1–4
Authors: Grünbart Michael
Published: October 2022

Procopius of Caesarea inserts numerous events of symbolic and prognostic character in his Gothic Wars. In Bella 5(1).20.1-4 he describes a game of competition between young Samnite shepherds imitating the current political situation. The loser was hung from a tree by them taking the common Late Roman punishment on the furca as a model. Due to the contingent appearance of a wolf he was not rescued and died. The tragic event is subsequently attributed predicting significance.
Revisiting the cod. 31 New Testament of the Hagia Lavra at Kalavryta
Authors: Konstantinidi Chara , Zarras Nektarios
Published: October 2022

Τhis paper revisits the luxurious Palaiologan illuminated manuscript of the New Testament, Codex 31 of the Hagia Lavra monastery in Kalavryta. Iconographic and stylistic characteristics of the miniatures are compared with others and with seals of the early fifteenth century, as well as with the wall-paintings of the Pantanassa Monastery at Μystras (ca 1430). It is argued that the codex was commissioned by Georgios Kantakouzenos Palaiologos, a close collaborator of Konstantinos Palaiologos, Despot of the Morea and subsequent emperor, who lived in Kalavryta and promoted his personal library, which was enjoyed even by Ciriaco of Ancona.
A late Byzantine book inventory in Sofia, Dujčev gr. 253 (olim Kosinitsa 265) – a monastic or private library?
Authors: Rance Philip
Published: October 2022

This study concerns an inventory of books, dated 1428/29, inscribed in Sofia, Dujčev gr. 253 (olim Kosinitsa 265), fol. 290r. Although the text was obscurely published in 1886, the vicissitudes of this codex over the following century impeded further research and the inventory continues to be overlooked in studies of Byzantine libraries, books and reading. A new edition, furnishing corrections and filling lacunae, together with a first translation and palaeographical analysis, provide a foundation for introducing this rare document and re-evaluating its context and significance. While the limited prior scholarship generally presumed compilation in a monastic library in 1428/29 and pursued inquiries based on that surmise, examination of Dujčev gr. 253 draws attention to annotations by a member of the Laskaris Leontares family, dated 1431-1437,which place the codex in private possession during this period. A survey of thirteen extant codices variously connected to this distinguished aristocratic dynasty, c.1400 - 1455, elucidates acquisition, ownership and use of books in this socio-cultural milieu, with particular reference to this family’s history and social networks. Comparative assessment of this sample of thirteen codices and the 21 items recorded in the book-list of 1428/29 affirms the view that it relates to a private rather than an institutional library and distinguishes its potential value for investigating aristocratic book culture in the late Byzantine era.

Using the complex stratigraphic structure model, we study the changes in remaining oil on the millimeter scale in different structural parts during the different water flooding development methods. According to the actual geological structure characteristics of the oil layer, We designed and produced the meter-level experimental model, which ensures the similarity between the model structure and actual oil layer structure. The recovery rate of the primary water flooding stage is 10.36%. The stage recovery rate addition of the change flow direction stage is 7.85%. The final recovery rate is 41.36%. The physical interlayer structure has an influence on the oil saturation change in the nearby layers. The oil saturation reduction value is highest in the left part of layer 3 in the primary water flooding stage, the reduction range is 24.81%. There are 2 parts and 1 part where the oil saturation decreases by more than 10.0% in the second boost flooding stage and the change flow direction stage, respectively.
Optimization of interpolation parameters based on statistical experiment
Authors: Zhang Jinming
Published: October 2022

Interpolation parameters are the basic elements of an interpolation algorithm in terrain environmental modeling. Different interpolation parameters produce different interpolation precisions, and the differences can be substantial. They are divided into deterministic parameters and uncertainty parameters. The optimization of uncertainty interpolation parameters is studied in this article. First, the methods of cross-validation, correlation analysis, and trend surface analysis are systematically used to identify and determine the optimal interval of interpolation parameters, which is helpful to solve the “black box” problem of parameter selection. Second, the significance degree of different parameters on the interpolation accuracy is given by using analysis of variance, which indicated that the high influence parameters are more helpful to improve the accuracy. This is an innovative conclusion.

Objectives

Children with epilepsy are at increased risk of vitamin D deficiency. We aimed to compare the effect of two ergocalciferol regimens given for 90 days.

Methods

Epileptic patients aged 5–18 years who received at least one antiepileptic drug (AED) for more than 6 months and had serum 25-OHD <30 ng/mL were randomized to receive 20,000 IU/10 d (standard dose, n=41) or 60,000 IU/10 d (high dose, n=41) of oral ergocalciferol. Serum Ca, P, Mg, ALP, iPTH and urine Ca/Cr ratio were measured at baseline and after 90 days of treatment. Change in serum 25-OHD and vitamin D status after treatment was evaluated.

Results

The initial serum 25-OHD in the standard dose and high dose group was 19.5 ± 4.9 and 18.4 ± 4.6 ng/mL, respectively. Serum 25-OHD after treatment was significantly higher in the high dose group (39.0 ± 11.5 vs. 27.5 ± 8.6 ng/mL, p<0.05). The average increase in serum 25-OHD in the high dose and standard dose group was 20.6 ± 11.4 and 7.2 ± 7.5 ng/mL, respectively (p<0.05). Normalized serum 25-OHD was achieved in 80.5% of the high dose group compared to 36.6% of the standard dose group (p<0.05). No adverse events were found. Patients with a BMI Z-score>0 had a 2.5 times greater risk of continued hypovitaminosis D after treatment compared to those with a BMI Z-score<0 (95% CI: 1.0–5.9, p<0.05).

Conclusions

Oral ergocalciferol 60,000 IU/10 d for 90 days was more effective at normalizing serum 25-OHD than 20,000 IU/10 d in epileptic children and adolescents who were receiving AEDs.
Russia under Putin in the Eastern Mediterranean: The Soviet Legacy, Flexibility, and New Dynamics
Authors: Gasimov Zaur
Published: October 2022

Russia has become an important player in the Eastern Mediterranean during the presidency of Vladimir Putin, setting up a military presence in the Crimea, South Caucasus, Syria as well as naval facilities in the Mediterranean. Moscow deepened its bilateral relations with NATO members Greece, France and particularly Turkey and has been able to profit from the new dynamics that have emerged in the Middle East North Africa (MENA) region. Russian policy towards the Eastern Mediterranean has been based on large-scale flexibility and its ability to combine elements of soft and hard power. Dependent on Russian grain and tourists and eager to cooperate with Moscow militarily, most non-EU countries of the Eastern Mediterranean have refused to institute anti-Russian sanctions of the sort imposed by the EU after Russia’s invasion of Ukraine in February 2022.
