Authors: Onchere Walter Omonywa , Weke Patrick Guge , Ottieno Joseph Makoteku , Ogutu Carolyne Adhiambo
Published: November 2022

Grouping insureds in clusters such as joint-life annuities imposes statistical dependence. In this paper, we propose the shared compound frailty approach in collective valuation of joint-life annuity products where most applications have been in bio-statistics. The positive stable compound process used entails the frailty mixing distribution with the weighted exponential, generalized exponential and weighted Weibull as the base force of mortality distributions calibrated on a large Kenyan insurer joint-life last-survivor dataset. The findings shows that the positive stable generalized exponential model addresses time-varying heterogeneity effects positively and negatively associated with dependence
Choice of the spectral window width by cross-validation: Case of the almost periodically correlated process with continuous time
Authors: Ekra Sylvestre Placide , Monsan Vincent
Published: November 2022

This work presents a procedure to choose the width of the spectral window used in the smoothing of a periodogram when estimating the spectral density of an almost periodically correlated process. The cross-validation procedure we propose is based on the estimation of the integrated square error using the "Leave-out-I" principle.

Una propuesta para promover la comprensión intuitiva de la validez lógica
Authors: García Duque Carlos Emilio , Arango Giraldo Pablo Rolando , Posada Ramírez Jorge Gregorio
Published: November 2022

El artículo presenta una propuesta para promover la comprensión de las nociones de posibilidad, necesidad y validez argumental. Por medio de un criterio psicológico, la propuesta busca que los estudiantes capten dichas nociones de forma intuitiva antes de comenzar a usar las pruebas formales de validez. Se muestra cómo puede adaptarse la propuesta en el uso de los diagramas de Venn y en la diagramación de algunas formas silogísticas que la teoría clásica del silogismo considera válidas pero que no aparecen como formas válidas en la diagramación canónica que usa los diagramas de Venn.

Authors: Sánchez Francisco , Martínez Habibe María Cristina , Díaz Sandra , Medina Nicolás , Riaño Jeisson , Paqui María Fernanda
Published: November 2022

Los ecosistemas urbanos incluyen áreas suburbanas y asentamientos conectados por corredores de conmutación y tierras afectadas por la energía y materiales del núcleo urbano. Estos ecosistemas presentan enormes retos para la conservación de la biodiversidad por la alta concentración de humanos, las marcadas perturbaciones, y en Colombia la información sobre la biodiversidad allí es limitada. Se hizo un inventario de las plantas vasculares, anfibios, reptiles sin plumas y con ellas (aves), y mamíferos en el campus de la Universidad Militar Nueva Granada, Sabana de Bogotá, cordillera Oriental colombiana, ~2550 m snm. El campus se ubica entre dos centros urbanos, Cajicá y Zipaquirá, y es un mosaico de ambientes urbanizados, de uso agropecuario, y con remanentes de ecosistemas naturales asociados al río Bogotá. Se registraron 205 especies de plantas, una especie de rana, una de serpiente, 80 especies de aves y 10 de mamíferos. La mayoría de los árboles del campus son plantados; una considerable proporción de plantas son exóticas y algunas son invasoras. Aves residentes y migratorias usan el campus, y representan casi el 40% de las especies conocidas para la Sabana. Entre los mamíferos hay seis especies no voladoras y posiblemente tres murciélagos, y también hay una especie exótica e invasiva, el ratón casero Mus musculus. El campus es refugio para especies amenazadas (e.g., Porphyriops melanops) y especies poco conocidas (e.g., Akodon sp.). Deben hacerse esfuerzos en el manejo adecuado del campus, e idealmente alrededor de él, manteniendo suficientes espacios verdes y humedales para conservar las especies silvestres.

Authors: Jaramillo Salazar Marco Tulio , Buitrago Escobar Diana Patricia , Henao Vasco Sonia Marcela , Galvis García John Henry
Published: November 2022

Las macrófitas acuáticas han sido utilizadas en procesos de biorremediación, ya que pueden absorber algunas sustancias disueltas y producir oxígeno mediante fotosíntesis. Con base en los estudios de remoción de compuestos tóxicos por parte de plantas acuáticas que permitan la depuración de aguas residuales, la presente investigación tuvo como propósito principal buscar la disminución de la contaminación por cianuro y la toxicidad de las aguas residuales del lavado de arena del proceso de cianuración de oro de la mina La Coqueta, mediante la utilización de macrófitas acuáticas flotantes (Eichhornia crassipes, Pistia stratiotes Salvinia auriculata); además, de acuerdo con los resultados de pruebas cualitativas, encontrar el destino final del cianuro en las plantas al ser absorbidos por éstas. El tratamiento de agua cianurada se realizó mediante un sistema de acuarios, los cuales contenían el agua proveniente de la mina, en ellos se depositaron las plantas para el tratamiento, se tomaron parámetros fisicoquímicos de control (pH, porcentaje de saturación de oxígeno y conductividad), además de la determinación de cianuro y toxicidad en el agua, pruebas cualitativas de compuestos nitrogenados en las plantas y bioensayos con Daphnia pulex en las plantas y en el agua tratada. Con base en los resultados de las pruebas cualitativas, se evidenció que las macrófitas pueden cambiar su metabolismo en condiciones de estrés y este cambio de metabolismo induce también a que se produzcan otro tipo de metabolitos secundarios no presentes naturalmente (e. g. glicósidos cianogénicos y alcaloides) en las plantas sometidas al tratamiento.La remoción de cianuro por parte de estas especies fue hasta del 86% al final del tratamiento, demostrando gran eficiencia para remover compuestos tóxicos del agua cianurada proveniente de la mina La Coqueta, ya que en los bioensayos realizados con Daphnia pulex indicaron que estos organismos podían resistir a las características del agua después del tratamiento con las plantas. Señalando que se puede realizar un tratamiento natural, ambientalmente seguro y económicamente viable que permita descontaminar el agua cianurada proveniente del lavado de las arenas del beneficio del oro a través del proceso de cianuración.
Presencia de Eleutherodactylus johnstonei (ANURA: ELEUTHERODACTYLIDAE) en Ibagué, Tolima, Colombia: el papel de los viveros comerciales
Authors: Gómez Martínez Mario J. , Llano Mejía Julián , Cortés Gómez Ángela María
Published: November 2022

La rana Coquí de las Antillas Eleutherodactylus johnstonei, es considerada una especie invasora de varios países de Centro y Sur América, la cual puede ocasionar efectos negativos al poner en riesgo la salud del hombre, debido a su aguda vocalización tornándose contaminación auditiva y por ser portadora de parásitos. Con el fin de identificar la fuente de introducción y los mecanismos de dispersión de la especie se reporta y se describe la contribución de los viveros comerciales de la ciudad de Ibagué con la llegada de E. johnstonei a la ciudad y de su posterior dispersión a las zonas residenciales por medio del transporte de plantas ornamentales. Individuos de la especie fueron observados en zonas residenciales y comerciales del centro de la ciudad en 2011, 2012 y 2013. Por medio de visitas nocturnas a viveros y recorridos por la ciudad se identificó la presencia de la especie en nueve de los 12 viveros visitados así como también el registro auditivo en siete barrios residenciales de la ciudad. Entrevistas semiestructuradas con viveristas permitieron identificar que la principal zona de donde se surten las plantas de los viveros ibaguereños es el departamento de Cundinamarca específicamente de los municipios de Fusagasugá y Mesitas del Colegio. Se reporta por primera vez a E. johnstonei en la localidad de Chinauta, Fusagasugá (Cundinamarca). Dadas las implicaciones biológicas y los potenciales impactos económicos de la invasión es necesario plantear estrategias de mitigación que conduzcan a controlar la presencia de la especie en los viveros mayoristas y a los de Ibagué para evitar la dispersión a otras zonas de la ciudad y el país.

Ética y narración (una reflexión fenomenológica)
Authors: Serna Castro Yobany
Published: November 2022

Ética y narración (una reflexión fenomenológica) consiste en una reflexión sobre la idea según la cual la literatura brinda elementos para comprender y analizar problemas filosóficos, morales y políticos de una manera diferente a como lo hace la filosofía. Se trata, además, de abordar el tema de la reflexión moral fenomenológicamente, acudiendo a un recurso distinto al de la filosofía: la literatura. Para hacer esto se hablará, en primer lugar, de cómo puede entenderse la moral desde la fenomenología, a través de las ideas de autores como Edmund Husserl y Emmanuel Lévinas. Posteriormente, se contextualizarán estas ideas acudiendo a las obras literarias El extranjero, de Camus y La náusea, de Sartre.
Fenomenotecnia, prácticas científicas y construcciones teóricoconceptuales. Sobre una aproximación neo-internista a la labor investigativa
Authors: Ortega Caro Cristian
Published: November 2022

Se presenta un protocolo orientado a interpretar las prácticas científicas desde una perspectiva microscópica. Si bien existe una vasta literatura sobre este enfoque –por ejemplo, el constructivismo científico– aquí se hará hincapié, fundamentalmente, en el entramado psico-técnico que implica la elaboración de los componentes lógicos, teóricos y metodológicos del trabajo investigativo; temática postergada por perspectivas que, como la mencionada, han obnubilado su complejidad y relevancia.
A objeto de reestablecer la autonomía del espacio técnico-racional de la labor científica, aquí, bajo la inspiración de Gastón Bachelard, se propone el concepto de fenomenotecnia situada en tanto recurso que puede guiar los análisis sobre la construcción de protocolos teóricoconceptuales en un proceso de investigación. Al contrario de lo que se estila en la mainstream science del campo, la hipótesis apela por la centralidad de la racionalidad científica, en tanto característica irreductible del entramado socio-psico-técnico de las prácticas científicas.
El punto de arranque de la indicación formal: la crítica heideggeriana a las operaciones de generalización y formalización
Authors: Abalo C. Francisco
Published: November 2022

En las últimas décadas se ha tomado gran conciencia dentro de los estudios heideggerianos de la relevancia de la indicación formal. En efecto, en ella se encuentra la pieza clave de la metódica filosófica de este pensador. Heidegger introduce por primera vez este concepto a través de una delimitación frente a otras operaciones conceptuales. El siguiente artículo se limitará a la exposición crítica que Heidegger hace de la generalización y de la formalización para mostrar que aquí late una discusión mucho más compleja con la fenomenología husserliana. La propuesta esencial de este artículo es que el problema acerca de los conceptos filosóficos se sitúa con Heidegger en el plano fundamental del problema de los principios metódicos de la investigación filosófica.
El sujeto del cambio
Authors: Briceño Domínguez Sebastián
Published: November 2022

Al enfrentar el problema de los intrínsecos temporales, las posiciones dominantes asumen que el sujeto del cambio es un particular concreto, i.e., un objeto que instancia propiedades intrínsecas en una posición temporal determinada. Posiciones minoritarias niegan la existencia del sujeto del cambio o aceptan a este último como un particular concreto de carácter contradictorio. En este artículo argumento (i) que las soluciones en oferta son incapaces de hacer sentido de las cambiantes apariencias; (ii) que esta incapacidad radica precisamente en una deficiente comprensión del sujeto del cambio; y (iii) que una comprensión del sujeto del cambio basada en un esquema categorial más tolerante sí nos permite hacer mejor sentido de ellas. Bajo este esquema, de raíces idealistas, el sujeto del cambio debe ser entendido como un “universal concreto”.
Progreso y Pórtico: las revistas seriadas de arquitectura y urbanismo en Medellín. De la ciudad tradicional al proyecto moderno
Authors: Cuervo Calle Juan José
Published: November 2022

Este texto tiene como objetivo indagar por la participación de dos revistas seriadas en torno al desarrollo urbanístico de Medellín (Colombia). La primera es Progreso, órgano de divulgación de la Sociedad de Mejoras Públicas; la cual expone el proceso de transformación urbana, su progreso y la instauración del civismo como instructivo para habitar la ciudad. La segunda es Pórtico, publicación seriada de la Facultad de Arquitectura de la Universidad Nacional, estableciéndose en Medellín como proclamadora de una cultura arquitectónica moderna. Para lograr este propósito se llevó a cabo una investigación de tipo documental estructurada en dos etapas: la primera fue la revisión bibliográfica existente sobre el tema y segundo, la indagación de material de archivo y revistas seriadas especializadas de la época, teniendo como fuente principal Progreso y Pórtico, partiendo de la pregunta central sobre la comprensión de la modernidad en Medellín. El encuentro de estas dos revistas en el segundo quinquenio de 1940, genera una tensión por divulgar una arquitectura y unas formas de producción de ciudad entre lo tradicional y lo moderno.

Involvement of Intracellular Ca²⁺ and Nitric Oxide in the Hydroxyurea-Induced Melanogenesis
Authors:   The Pharmaceutical Society Of Korea, Lee Yong Soo
Published: November 2022

The molecular mechanism underlying hyperpigmentation as an adverse side effect of the anticancer drug, hydroxyurea (HU), was investigated in B16 melanoma cells. HU increased the melanin content and intracellular Ca²⁺ concentration in a dose-dependent manner. These effects were significantly reduced by treatment with the intracellular Ca²⁺ release blockers, dantrolene and 2-aminoethoxidiphenylborate (2-APB). Additionally, HU induced the production of nitric oxide (NO) in a time- and dose-dependent manner, and this was significantly blocked by inhibitors of the increase in intracellular Ca²⁺ levels(bis-(o-aminophenoxy)-ethane-N,N,N',N'-tetraacetic acid/acetoxymethyl ester, dantrolene, and 2- APB). Furthermore, the HU-induced increases in NO and melanin production were significantly suppressed by NG-nitro- L-arginine methyl ester and 2-(4-carboxy-2-phenyl)-4,4,5,5-tetramethylinidazoline-1-oxyl-3-oxide, an NO synthase inhibitor and an NO scavenger, respectively. These results suggest that HU-induced melanogenesis through NO and an increase in intracellular Ca²⁺ levels may be involved in the mechanism of its hyperpigmentation effect.
Cost-effectiveness of Combination Therapy of Anticoagulants/antiplatelets with Proton Pump Inhibitors: A Systematic Review
Authors:   The Pharmaceutical Society Of Korea, Lee Yeon-Woo , Kwon Sun-Hong , Kim Na-Hyun , Lee Eui-Kyung
Published: November 2022

Anticoagulants/antiplatelets are effective in preventing cardiovascular diseases (CVDs). However, as an adverse effect, the risk of upper gastrointestinal bleeding (UGIB) leads to additional costs due to increased treatment and decreased quality of life. Accordingly, the administration of proton pump inhibitors (PPI) is recommended to prevent UGIB. We conducted a systematic review of economic evaluations of PPI co-therapy for patients taking long-term anticoagulants/ antiplatelets to prevent CVDs to examine the cost effectiveness of PPI co-therapy. We searched literature from PubMed and EMBASE with keywords including types of economic evaluations and active ingredients of anticoagulants and antiplatelets on 13/07/2022. Two independent reviewers conducted a systematic review. As a result, six economic evaluation studies were identified. All studies compared PPI co-therapy with low-dose aspirin to prevent CVDs. We confirmed the cost-effectiveness of PPI co-therapy with the respective incremental cost-effectiveness ratio (ICER) in each base case. In the sensitivity analyses, the PPI cost and adherence influenced the ICER the most. The quality of reporting, which was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist, was 87-96%. In the present study, we found that PPI co-therapy was cost-effective and tended to improve the patient’s life years and quality-adjusted life years. These results can be used as evidence for further economic evaluation studies to verify the costeffectiveness of anticoagulants/antiplatelets and PPI co-therapy.
Generation of glioblastoma spheroid model using an orbital shaker v1
Authors: KHOTCHAWAN WANNAWAT
Published: November 2022

Glioblastoma multiforme (GBM) is the most common and aggressive type of primary brain tumor with no effective treatment but a high fatality rate. Thus, a new treatment is still urgently required. The U251 cell line is widely used as a model for investigating GBM characteristics and developing therapeutic treatments. A conventional two-dimensional (2D) culture system is routinely used for maintaining and propagating U251 cells for experiments. However, the 2D system does not correctly mimic the in vivo tumor complexity and tumor microenvironment affected GBM behaviors and responsiveness to drugs treatment. Recent research suggests that three-dimensional (3D) culture methods, such as a spheroid model, could be a better platform for mimicking tumor behavior in vivo. The 3D model can imitate cellular activity, complexity, and providing a much more accurate representation of tumor profiles and medication response in vivo. Here, we provide a simple but yet effective protocol to generate the glioblastoma spheroids from the U251 GBM cell line using an orbital shaker for investigating GBM characteristics and developing therapeutic treatments. This protocol might be applicable to other type of tumors for studying factors effecting tumor growth.

Non-Formal Cultural Infrastructure in Peripheral Regions: Responsibility, Resources, and Regional Disparities
Authors: Fobel Lea
Published: November 2022

Non-formal cultural education (NCE) infrastructure has recently been at the centre of discussion regarding the promotion of equal opportunities as well as social cohesion and resilience. The German government strives to ensure equivalent living conditions, including access to education throughout the country. Although NCE infrastructure is considered a service of general interest, it is a voluntary service that districts are not obliged to provide. Research shows that NCE infrastructure provision and funding vary significantly between regions and that qualitative case analyses are needed to adequately contextualise key factors for the provision of NCE infrastructure. These developments and findings raise many questions against the background of spatially differentiated socio-economic landscapes. The article analyses two peripheral regions in Germany by examining key factors for the local provision of NCE infrastructure based on content analysis of qualitative interviews. This article aims to understand how NCE infrastructure is provided in peripheral regions to discuss the effect of these dynamics on the development of equivalent living conditions in Germany. The results show that citizens in peripheral areas have found alternative ways of providing NCE infrastructure due to the lack of financial resources available from the public sector. Self-responsibilisation, civic engagement, and individual commitment provide and sustain large parts of NCE infrastructure in rural areas. These developments impede the provision of equivalent living conditions in Germany while enabling a more resilient community through civic engagement. This article, therefore, provides an important contribution to the discourse on social and regional inequality.
DIGITAL CULTURAL HERITAGE UNDER ATTACK: SAVING UKRAINIAN CULTURAL HERITAGE ONLINE (SUCHO)
Authors:   Stanford University, Dombrowski Quinn , Kijas Anna ,   Tufts University, Majstorovic Sebastian ,   Austrian Center for Digital Humanities & Cultural Heritage
Published: November 2022

Cultural heritage is at the heart of Russia’s war on Ukraine, still underway five months after the invasion on February 24, 2022. Statements from the Kremlin indicate that the fundamental goal of Putin’s regime is to undermine and eliminate the distinct and distinctive Ukrainian national identity, culture, and language – three concepts that are manifested through cultural heritage. During a war with such an agenda, internationally recognized frameworks such as the 1954 Hague Convention can be subverted, turning the blue shield symbol meant to protect cultural property into a target. While practices codified by the Hague Convention provide both opportunities and challenges for physical cultural heritage in this war, the biggest challenge for preserving digital cultural heritage is the lack of precedent. Saving Ukrainian Cultural Heritage Online (SUCHO, sucho.org) began on March 1, 2022, as an emergency response effort organized by three digital humanities practitioners, and quickly grew to over 1,300 volunteers. In this brief essay, the three co-founders – Anna Kijas, Sebastian Majstorovic, and Quinn Dombrowski – reflect on the first five months of SUCHO, the differences between physical and digital cultural heritage, the urgency of preserving digital cultural heritage during a war, and the importance of these materials for the future of art history.

Variation of Pinning Force Density Throughout the TSMG Y123 Superconductor with Location
Authors: ÇAKIR Bakiye
Published: November 2022

Top seeded melt growth (TSMG) Y123 sample with 35 mm diameter was produced by using Nd123 seed and its superconducting parameters such as transition temperature (Tc), critical current density (Jc) and pinning mechanism were locally examined by taking small specimens which are containing defects in different number, size and distribution from different locations throughout the sample. The Tc of the main sample was determined from the resistivity measurement as 93.4 K. It was observed that the Jc was higher in the region close to the seed, while the Jc decreased towards to the edge or the deeper regions of the sample. Effective pinning mechanisms at different temperatures were determined by plotting the curves of the pinning force density (fp) of the specimens versus reduced magnetic field (h= Ha/Hmax) and the locational variations of the fp were examined. It was seen that below the value of h ≈ 0.2, normal point pinning was dominant at 30 and 50 K, while surface pinning was dominant at 77 K, in the all specimens. In addition, a transition was observed between two different pinning mechanisms when the Hmax > h > 0.2. The transition was took place between  and normal point pinning at 30 and 50 K while it was seen between  and surface pinning at 77 K.
Наука о цивилизациях как фундаментальная основа новой парадигмы обществознания в монографии академика РАЕН Ю. В. Яковца
Authors: Колин Константин Константинович
Published: November 2022

В статье проведен анализ основных положений науки о цивилизациях, изложенных в новой фундаментальной монографии академика РАЕН Ю. В. Яковца, изданной в 2021 г. в России. Показано, что эти положения создают научную основу новой парадигмы обществознания, которая в настоящее время является крайне необходимой не только для фундаментальной науки, но также и для решения прикладных задач, связанных с обеспечением национальной и глобальной безопасности.

Эти задачи сегодня объективно выдвигаются на первый план в связи с нарастанием системного кризиса современной цивилизации и обострения геополитической напряженности между странами Востока и Запада. Решение этих задач требует формирования цивилизационного мировоззрения у интеллектуальной элиты общества, которое является необходимым условием для преодоления имеющихся идеологических разногласий и перехода на путь диалога и партнерства цивилизаций в интересах решения общих глобальных проблем.
The Influence of Cumulative Intensity on Macroseismic Source Parameters: The Case of 2016–2017 and 1703 Seismic Sequences (Central Italy)
Authors: Graziani Laura , Rovida Andrea , Tertulliani Andrea
Published: November 2022

The macroseismic source parameters of earthquakes occurring within a sequence are strongly influenced by cumulative damage effects. When we deal with historical seismic sequences, in addition to the cumulative intensities, other intrinsic uncertainties due to the scarcity and indeterminacy of sources come into play. These issues imply that the parameterizations of the single earthquakes within a historical seismic sequence are not univocal and that all the uncertainties that are addressed when assessing macroseismic intensity should be carefully considered in the parameter estimation. In the light of these considerations, we performed some tests on the 2016–2017 and 1703 seismic sequences, which occurred in the same area in central Italy, to compute the macroseismic source parameters by means of two independent methods. Results show that the cumulative effects arising from multiple damaging earthquakes can cause biases in the intensity assessments, which affect the computed magnitude and epicentral locations. To reduce bias in macroseismic intensities due to cumulative damage, we illustrate a simple procedure, called cumulative intensity subtraction (CIS), which consists in discarding the localities strongly damaged by the early earthquakes of a sequence from the intensity distributions used for computing the macroseismic source parameters of the subsequent earthquakes. The outcomes show that, for the 2016 seismic sequence, the CIS approach provides locations in agreement with the instrumental epicenters and with the causative faults. For the 1703 sequence, the CIS approach along with explicit accounting for the indeterminacy in intensity assignments give a range of equally plausible solutions. The CIS represents an exploration of a simple strategy that stems from an attempt to give significance to macroseismic intensity in the presence of cumulative damage.
GrowClust3D.jl: A Julia Package for the Relative Relocation of Earthquake Hypocenters Using 3D Velocity Models
Authors: Trugman Daniel T. , Chamberlain Calum J. , Savvaidis Alexandros , Lomax Anthony
Published: November 2022

Relative relocation techniques are widely used to improve the resolution of earthquake hypocenter positions. Here, we present GrowClust3D.jl—an open-source software package written in the programming language Julia that builds and improves upon the original GrowClust algorithm, an established relative relocation technique based on cluster analysis instead of a more traditional matrix inversion approach. The adoption of Julia’s modern programming environment allows for greater flexibility in GrowClust3D.jl’s algorithm design and its computational implementation. Notable additions to the GrowClust3D.jl package include (1) several parallel processing options to improve efficiency in uncertainty quantification routines, (2) incorporation of geographic map projections and station elevations during the relocation process, and (3) the ability to use travel-time tables derived from 3D velocity models. We demonstrate the new features of the software package on relocation problems of different scales in Nevada, California, Texas, and New Zealand, where in the latter two cases the use of a 3D velocity model helps resolve structures that remain obscure with earlier versions of GrowClust. We expect that the new GrowClust3D.jl software package will become a valuable public resource for the earthquake science community.
Investigating the Performance of Sensor-Driven Biometrics for the Assessment of Cognitive Workload
Authors:   , MacNeil Emma Katherine , Izzetoglu Kurtulus
Published: November 2022

Cognitive workload changes in the assessment of human performance have long been monitored through the use of subjective self-reports, physiological, or neuro-physiological measures. Wearable sensors allow us to monitor direct physiological changes associated with cognitive workload in real time. This thesis focuses on utilizing multiple physiological and neurological measures: functional near-infrared spectroscopy (fNIRS), eye-tracking, electrodermal activity, heart rate, and respiratory rate; in order to assess cognitive workload changes during different simulation-based tasks designed within the context of Federal Law Enforcement Training. The primary objective is to use multi-modal sensors and machine learning (ML) approach as an objective assessment method and to investigate which set of biometrics serves as the best predictor of cognitive workload. To achieve this objective, several biometrics, including prefrontal cortex (PFC) oxygenation changes, heart rate, and respiratory rate, were collected in both high and low workload conditions in simulated use of force (UOF) scenarios. These biometrics were then used to train logistic regression, feature mapping, support vector machine (SVM) and linear discriminant analysis (LDA) classifiers. F1-score and accuracy measures were used to evaluate the performance of these classifiers. Oxygenation changes in the left anterior medial PFC region and the combined biomarkers including oxygenation changes in the PFC and heart rate revealed the highest performing feature sets across all the classifiers. Future work should include the use of non-linear classification models and study of additional biomarkers to enhance training outcomes and performance.

International space activities are regulated by seven main documents that had come into effect between the 1963–1974 period. For almost half a century, the world order has been changed, scientific and technological progress has made significant changes in the quality of using the near-Earth space environment. Offensive and defensive space assets have changed also. This article systematizes the means of counterspace capabilities and evaluates the counterspace potential of China, India and Iran on the basis of this systematization.
Prawda jako wartość chroniona prawnie. Problem odpowiedzialności prawnej za naruszenie dóbr osobistych związanych z rozpowszechnianiem nieprawdziwych informacji (fake news)
Authors: Tylec Grzegorz
Published: November 2022

In the Polish legal system, there are no legal regulations that allow to block publication in case of disseminating false information (fake news) in internet. The article encompass analysis if legal device like personal rights under polish civil law can be used to protect against the fake news. Analysis was made to answer the questions whether the polish model of the protection of personal rights meets the purpose which is protection against fake news or whether it contains gaps that allow publishing untrue information with impunity. The conclusions is proposals to change legal regulations that limit the possibility of determination of the person who publishes fake news.

Affinity in the XIV–XV Centuries: Means of Formation and Social Functions
Authors:   Moscow Pedagogical State University, Kudryakov V. V.
Published: November 2022

Evolution of feudal system on the verge of the thirteenth and fourteenth centuries entailed а decline of military service based on former tenurial bonds and its substitution by the system of contracted obligations which facilitated development of the institution of affinity. These communities forming around magnates executed not only military functions but became the centers of social, political and administrative activity. They defended interests of their members and promoted matrimonial and economic links among them. Prosperous affinities gained control over local executive and judicial power as well as elections to the House of Commons. However, their struggle for dominance contributed to a considerable extent to instability of political development in England in the fourteenth and fifteenth centuries.
The Legal Status of a Slave in the Early Medieval England
Authors:   Voronezh State Technical University, Zolotarev A. Y.
Published: November 2022

The article is about slavery in the early medieval England, a problem poorly discussed by Russian scholars. Slave’s legal status and capacity are under consideration. The author draws a conclusion that slaves in the Anglo-Saxon society possessed a certain degree of the legal capacity though diminished by comparison to that of the freemen. Slaves bore responsibility for their misdeeds, could have a family and own a property. These were prerequisites for disappearance of slavery and merging of the slaves and the lowest strata of the freemen into villainage.

Published: November 2022

This research aimed to study the types and purposes of dysphemisms in Mandarin online news platforms Guoji Ribao and Hao Bao. Ten news articles, dating from August to September 2021, were collected. The collected data were analyzed through data reduction, data presentation, conclusion drawing, and data verification. In the data analysis, the study was based on the Allan and Burridge dysphemism theory, and in describing the meaning of each dysphemism sentences, a lexical semantics approach was used. The results showed that Guoji Ribao and Hao Bao applies dysphemism in their news content and most of them are found as words inserted into sentences. Based on the findings, dysphemism is classified into three types: the use of dysphemism to address a person or a group of people, certain conditions, and certain activities. Each classified data showed different purposes. The purpose of using dysphemism is to demean a person or a group of people for the bad deeds they have committed, to demean someone of a lower position, to give negative nicknames, to give terrifying impressions to a situation, to give negative impression toward an activity and to compare two unequal things.
Keywords: dysphemism, Guoji Ribao, Hao Bao, phenomenon, COVID-19.
