Effect of Family-centered Empowerment Model on Quality of Life of Patients with Hypertension
Authors: Asadollahi Hamedani Mahsa , Salar Alireza , Kermansaravi Fatihe
Published: October 2021

Background: Nowadays, the high prevalence of hypertension and its serious complications for affected patients have made this disease a major health issue worldwide. Hypertension, like other chronic diseases, reduces the patients’ quality of life. Maintaining and improving their lifestyles requires the serious support of families. Objectives: This study aimed to explore the effect of the family-centered empowerment model on the quality of life of patients with hypertension. Methods: This clinical trial was performed on 70 hypertensive patients who were referred to two comprehensive health centers in Zahedan University of Medical Sciences in Zahedan, southeastern Iran, in 2020. The participants were selected and randomly allocated based on the inclusion criteria to the intervention (n = 35) and control (n = 35) groups using the consort. The participants in the intervention group received training in four 60-min sessions individually based on the family empowerment model. To collect data, a personal information form and the Quality of Life Questionnaire for hypertensive patients were used. The questionnaire was completed before the intervention and one and three months after the intervention by a self-report method. The collected data were analyzed by SPSS-22 using the independent samples t test, chi-square test, and repeated-measures analysis of variance. Results: The results of repeated-measures analysis of variance regarding the effect of time and group on the quality of life showed a statistically significant difference in the second and third phases between the two groups. In other words, the two variables of intervention and time affected the mean score of quality of life, and a statistically significant difference was observed in the measured time intervals (P < 0.001). Conclusions: This study showed that implementing the family-centered empowerment model improves the quality of life of patients with hypertension. Therefore, we recommend employing this method by nurses to engage the patients with chronic diseases and their families in the process of treatment.
Self-Deceptive Inquiry
Authors: Scott-Kakures Dion ,   Philosophy Documentation Center
Published: October 2021

I develop the claim that paradigmatic cases of self-deceptive inquiry and belief-formation result from cognitive disorientation. In cognitive disorientation, the data, experiences, and practices we make use of in typical inquiry lead us awry in systematic fashion. The self-deceiver encounters a puzzle or a threat to her picture of the world; this doubt or uncertainty gives rise to questions she struggles to settle. Drawing on the theory of cognitive dissonance, I show that while taking herself to be engaged in the familiar effort to settle a question, she undermines, by her own efforts, her success in achieving that goal. I appeal to two elements of such disorientation: Confusion of Aim and Misleading Feedback. I argue that we can find a role for both in the self-deceiver’s effort to settle a question.
Da Essência do Jardim. Aproximações a Uma Categoria Filosófica
Authors: Veríssimo Serrão Adriana ,   Philosophy Documentation Center
Published: October 2021

Avant toute description des jardins singuliers, ou même d’une approche historique ou typologique, le Jardin, en tant qu’espace mix te dû à l’action humaine sur une base naturelle qui per siste au-delà de l’action même devient un défi à la philosophie. Partant de la vision du Jardin en tant que catégorie synthétique où se croisent plusieurs axes conceptuels: transcendance/imanence, nature/art, nature/culture, l’article analyse quelques figures de la modernité et sa correspondance avec des principes esthétiques (Renaissance, Barroque, Lumières). Par contre, le doute sur la capacité autofondatrice de l’oeuvre humaine et la reconnaissance de l’origine naturelle de l’existence, demandent aujour-d’hui à la vision du Jardin d’autre cadres de référence, soit l’ontologie, soit l’étique du souci.
Agostinho e Jaccottet
Authors: Ferreira Ana Rita de Almeida ,   Philosophy Documentation Center
Published: October 2021

A experiência do jardim é um fenómeno com especificidades que ultrapassam as esferas da apreciação da arte e da natureza. É um a experiência que amplia a compreensão do ser no mundo e que obriga a uma transversalidade entre domínios vários d a esfera do saber. Ao nível da filosofia, o jardim proporciona uma forma única de conceptualização, sobressaindo como categoria sintética em que physis e poiesis se enleiam e apontam para uma concepção da natureza em ampla relação com as formas de consciência que o homem tem de si, da sua posição no mundo e da sua relação com o real. É com base nesta perspectiva que o presente texto propõe uma abordagem ao jardim no contexto do percurso biográfico e teórico de Santo Agostinho, a par da análise da obra A travers un verger, do poeta Philippe Jaccottet. O encontro improvável entre dois autores tão distintos, através da figura do jardim, reflecte o descentramento do sujeito, fundado na estética, em articulação com a experiência dos limites e da transcendência.
O Jardim: Retorta de Alquimista
Authors: Dias Isabel Matos ,   Philosophy Documentation Center
Published: October 2021

Esta reflexão visa estabelecer uma ana logia entre texto e jardim, privilegiando o texto poético e procurando mostrar a textura poética do jardim. Para mostrar a sobreposição entre o “livro da natureza” e o “livro de poesia” recorreu-se a um parque público contemporâneo português dedicado à poesia: o Parque dos Poetas, Salientou-se, por um lado, o exercício de misturas e de interacções de elementos diversos, patentes num jardim, aproximando-o da retorta do alquimista, por outro, tentou-se fazer uma hermenêutica desse jardim, desvendando a sua estrutura subjacente - a árvore e a folha - e a articulação entre espaços, formas, materiais, elementos, cores.
Descartes, the Savage, and the Barbarian
Authors: Westmoreland Peter ,   DePaul University
Published: October 2021

Philosophers struggle to identify a conception of race in Descartes’s philosophy. Yet, Descartes was not wholly silent on matters of foreign ethnicity and identity. This paper compares Descartes’s various statements on savages and barbarians, which have never been methodically analyzed. A tensive view emerges across several texts wherein Descartes asserts that all persons are rational while simultaneously presuming the epistemic inferiority of the foreign other construed as “savage” or “barbarous.” Further examination indicates that prejudice against this foreign other is endemic to both Descartes’s epistemology and his conception of the mind-body union.

¿Guerra anticolonial o guerra civil? Análisis historiográfico sobre el protagonismo étnico en la independencia del Ecuador según los textos escolares de Historia (1915-2015).
Authors: Silva Guijarro Víctor H.
Published: October 2021

El presente trabajo consiste en un análisis historiográfico sobre el protagonismo que tuvieron los distintos grupos étnicos en la Guerra de Independencia del Ecuador según los textos escolares de Historia publicados entre 1915 y 2015. Se han utilizado como fuentes historiográficas los textos escolares de Historia, debido a que desde el siglo XX las políticas educativas ecuatorianas los han utilizado como instrumentos ideológicos para llevar a cabo la construcción de una identidad nacional común cimentada a partir de los presupuestos de la Historia Patria del siglo XIX. El empleo de la enseñanza de la Historia a través de los textos escolares para consolidar esa identidad nacional del siglo XIX se hace patente en el análisis sobre el protagonismo étnico en la Independencia, donde dichos textos explican este acontecimiento como un proyecto de construcción nacional dirigido por las élites criollas cuyo supuesto objetivo principal era liberar a todos los “ecuatorianos” de una presunta opresión monárquica ejercida por un enemigo extranjero: el “español”. Pese a que hay autores que han manifestado que indígenas, negros, mestizos, zambos, pardos, mulatos, cholos, obtuvieron pocos beneficios de la Independencia, todos los textos escolares no dudan en confirmar que gracias a los esfuerzos de las élites criollas, héroes de la Patria a los que hay que venerar y ensalzar, la República del Ecuador pudo ser libre.

The present work consists of a historiographic analysis of the protagonism that the different ethnic groups had in Ecuador's War of Independence according to the history textbooks published between 1915 and 2015. History school textbooks have been used as historiographic sources, because since the 20th century Ecuadorian educational policies have used them as ideological instruments to carry out the construction of a common national identity based on the assumptions of the 19th century Patriotic History. The use of the teaching of history through school texts to consolidate this 19th century national identity is evident in the analysis of the ethnic protagonism in the Independence, where these texts explain this event as a project of national construction directed by the Creole elites whose supposed main objective was to free all “Ecuadorians” from an alleged monarchical oppression exercised by a foreign enemy: the “Spanish”. Although some authors have stated that indigenous people, blacks, mestizos, zambos, pardos, mulatos and cholos obtained few benefits from Independence, all the school texts do not hesitate to confirm that thanks to the efforts of the Creole elites, heroes of the country who are to be venerated and praised, the Republic of Ecuador was able to be free.

Asociacionismo inmigrante y nuevas formas de acción política. Facebook y la participación online de inmigrantes mexicanos en Estados Unidos.
Authors: Hernández Vega Leticia , Escala Rabadán Luis
Published: October 2021

Si bien el despliegue de acciones políticas ha sido una de las diversas funciones de las asociaciones de inmigrantes, en tiempos recientes muchos de estos grupos han incursionado en el uso de herramientas digitales para hacer política en favor de sus miembros y connacionales frente a los gobiernos de los países de llegada y de origen. En este artículo documentamos la creciente presencia de las asociaciones de inmigrantes mexicanos en Estados Unidos en las plataformas de Internet y explicamos su importancia al permitir un contacto directo, horizontal e inmediato entre dichas asociaciones, sus miembros y otros actores sociales y políticos, tanto de México como de Estados Unidos. Para ello, analizamos las acciones políticas de diversas asociaciones de inmigrantes mexicanos radicados en dicho país en la plataforma Facebook, con el fin de evidenciar los alcances de esta participación en lo que denominamos la “arena política glocaline”. Concluimos que el uso de espacios digitales amplía las dimensiones de la esfera pública, al abrir el acceso a múltiples voces desde la multi localidad, aunque en términos de efectos políticos directos los resultados pueden ser contingentes.

Although the deployment of political actions has been one of the various functions of immigrant associations, in recent times, many of these groups have been increasingly using digital tools to make politics in favor of their members and fellow compatriots vis-à-vis the governments. of the countries of arrival and origin. In this article we document the growing presence of Mexican immigrant associations in the United States on Internet platforms, and we explain their importance by facilitating direct, horizontal and immediate contact between associations, their memberships, and other social and political actors, both from Mexico and the United States. For this purpose, we analyze the political actions of various associations of Mexican immigrants based on the Facebook platform, in order to demonstrate the scope of this participation in what we call the "glocaline political arena”. We conclude that the use of digital spaces broadens the dimensions of the public sphere, by opening access to multiple voices from multiple locations. However, their direct political effects may be contingent.
Hacia un marxismo cubano. El Departamento de Filosofía de la Universidad de La Habana en sus primeras etapas (1962-1965).
Authors: González Lage Valeria
Published: October 2021

El Departamento de Filosofía de la Universidad de La Habana fue creado fruto de la Reforma Universitaria (enero de 1962) que introducía la obligatoriedad de enseñar filosofía marxista en todas las carreras universitarias y socializar la teoría científica adoptada por la Revolución cubana. Existiría hasta 1971, año en el que cambió de denominación, programas y profesorado. El artículo arroja luz sobre el proceso de creación del Departamento y la evolución de su visión respecto a la enseñanza y teoría del marxismo-leninismo en sus primeras etapas: desde un marxismo ortodoxo y manualista hacia la búsqueda de un punto de referencia cubano, antiimperialista y tercermundista. A través de fuentes orales y de archivo, el trabajo pretende analizar cómo y por qué nació el Departamento, sus objetivos y fuentes teóricas, y el cambio de perspectiva que experimentó su profesorado desde su creación hasta 1965, así como los principales factores que lo incentivaron.

The Philosophy Department of the University of Havana was created as a result of the University Reform (January 1962) that incorporated the obligation to teach Marxist philosophy in all university degree programmes and to socialize the scientific theory adopted by the Cuban Revolution. It would exist until 1971, the year in which it changed its name, programmes, and teaching staff. The article casts light on the formative process of the Department and the evolution of its conception regarding the teaching and theory of Marxism-Leninism in its early stages: from an orthodox and manualist Marxism towards the search for a Cuban, anti-imperialist, and Third-Worldist point of reference. Through oral and archival sources, this work aims to analyse how and why the Department was born, its objectives and theoretical sources, and the change in perspective that its teaching staff experienced from its creation to 1965, as well as the main factors that encouraged it.

Published: October 2021

Los MOOC se configuran como una de las tecnologías que, en los últimos tiempos, vienen ganando terreno en el campo educativo como nuevos enfoques en la educación a distancia, incrementándose su presencia en las instituciones educativas y el nivel de investigaciones y publicaciones que giran alrededor de estos desarrollos tecnológicos. En concreto, esta investigación se centra en el t-MOOC basado en la tarea. Se presenta la evaluación de un t-MOOC diseñado y producido para el desarrollo de competencias digitales del profesorado universitario a través del juicio de expertos según el Marco DigCompEdu. En su evaluación participan 172 expertos que obtienen un índice de competencia experta igual o superior a 0,9. Las puntuaciones alcanzadas permiten señalar que los expertos valoraron el t-MOOC de manera muy positiva, tanto de forma conjunta como individual. Igualmente, el estudio pone de manifiesto la significación del Coeficiente de Competencia Experta (CCE) a la hora de discriminar de forma más adecuada y justificada la selección de los expertos. Por este motivo, se reflexiona sobre las posibilidades didácticas que este tipo de tecnología añade a los nuevos escenarios educativos.

MOOCs are configured as one of the technologies that in recent times have been gaining ground in the educational field as new approaches in distance education, increasing their presence in educational institutions and the level of research and publications that revolve around these developments technological. Specifically, this research focused on the task-based t-MOOC. The evaluation of a t-MOOC carried out for the development of digital competences (DigCompEdu model) of university teachers is presented through the judgment of experts. 172 experts participate in its evaluation, obtaining an expert competence index equal to or greater than 0.9. The scores achieved allow us to indicate that the experts valued the t-MOOC very positively, both jointly and individually. Likewise, the study shows the significance of the Expert Competence Coefficient (ECC) when it comes to discriminating in a more adequate and justified way the selection of experts. For this reason, we reflect on the didactic possibilities of this type of technology in the new educational settings.
The effects of teacher’ feedback
Authors: Rochera María José , Engel Anna , Coll César
Published: October 2021

A pesar de su importancia, los efectos de la retroalimentación en entornos en línea no han sido ampliamente evaluados; tampoco hay consenso sobre cómo deben medirse. El objetivo de este estudio exploratorio es analizar los efectos de la retroalimentación del profesorado durante el desarrollo de un foro de discusión en línea. Durante un período de tres semanas, los participantes (14 estudiantes universitarios y su tutor) participaron en un debate virtual sobre el uso de Wikipedia con fines académicos, utilizando la plataforma Knowledge Forum (los participantes realizaron 328 publicaciones en total). Sobre la base de las características de los entornos de aprendizaje en línea, desarrollamos un modelo multidimensional para estudiar los comentarios del profesor y sus efectos durante la interacción en línea. Los resultados muestran los principales efectos de la retroalimentación tanto en la discusión de los estudiantes sobre los temas de aprendizaje -efecto en cadena y efecto en racimo-, como en las reglas de participación en el debate. El documento concluye con una discusión sobre las implicaciones teóricas y prácticas de estos resultados.

Despite its importance, the effects of feedback in online environments has not been widely assessed; nor is there any consensus on how it should be measured. The aim of this exploratory study is to analyse the effects of teacher feedback during the development of an online discussion forum. Over a three-week period, the participants (14 university students and their tutor) engaged in a virtual debate on the use of Wikipedia for academic purposes, using the Knowledge Forum platform (participants made 328 posts in total). Based on characteristics of online learning environments, we developed a multidimensional model to study feedback and its effects during online interaction. The results show the main effects of the teacher's feedback both on the students' discussion about learning topics –chain effect and cluster effect– and on the rules of participation in the debate. The paper concludes with a discussion on the theoretical and practical implications of these results.

Published: October 2021

Este artículo presenta una evaluación del nivel taxonómico de las actividades de aprendizaje de los MOOC de la Colección de Aprendizajes Clave diseñado para actualizar a profesores de educación primaria de México en enfoques y contenidos del nuevo plan de estudios. Con tal fin se realizó un mapeo de la estructura general de los MOOC. Se definió una tipología de segmentos de actividad (TSA) para realizar un análisis cuantitativo de contenido y clasificar las actividades de aprendizaje de acuerdo a la taxonomía de Anderson y Krathwohl (2001). Esta tipología se valoró por un comité de expertos y se aplicó al conjunto de actividades de aprendizaje identificadas. Se encontró que la mayoría de las actividades se distribuyen en dos de los seis niveles de la taxonomía, 36% se relacionan con la comprensión y 20% con el análisis. Asimismo, cuatro de los segmentos de actividad corresponden a actividades auténticas que favorecen la transferencia del aprendizaje, lo cual representa 20% de las actividades. Se concluye que la TSA es útil tanto para diseñadores como para evaluadores a fin de valorar las demandas cognitivas de un curso masivo y abierto para el logro de sus objetivos.

Published: October 2021

Los encuentros científicos en línea motivados por la Covid19 han sido una práctica muy común recientemente. No es nueva esta modalidad, pero hoy por su crecimiento solicitan soluciones tecnológicas estables y experimentadas. En un año se ha avanzado mucho en diferentes funciones en los sistemas de videoconferencias, como también en nuevas fórmulas para presentar los trabajos científicos como son los videopóster, que utilizando tecnologías emergentes de anotaciones de vídeo permiten una mayor interacción y debate en los trabajos científicos en un evento en línea. El estudio analiza la cantidad y la calidad de las anotaciones dentro de las cuales se recogen los debates e interacciones entre los autores y los oyentes de una mesa de comunicaciones con videopóster frente a otra presencial. La evaluación de la experimentación se realiza bajo estudio descriptivo de datos cuantitativos y cualitativos, y técnicas de análisis de contenidos “Q-análisis” de las 437 anotaciones y las 238 intervenciones en los 16 videopóster de un evento en línea. Los resultados muestran el doble de participación en la modalidad de videopóster frente a las Comunicaciones presenciales, al tiempo que se enumera un número relevante de beneficios que ofrecen los videopóster para el desarrollo de eventos en línea y redes profesionales de aprendizaje.

Online scientific meetings motivated by Covid19 have been a very common practice recently. This modality is not new, but today, due to its growth, it requires stable and experienced technological solutions. In one year, much progress has been made in different functions in videoconferencing systems, as well as in new formulas for presenting scientific papers, such as videoposters, which, using emerging video annotation technologies, allow greater interaction and discussion of scientific papers in an online event. The study analyzes the quantity and quality generated by discussions between authors and listeners at a videoposter presentation table versus a face-to-face one. The evaluation of the experiment is performed under a descriptive study of quantitative and qualitative data, and content analysis techniques "Q-analysis" of the 450 annotations and 355 interventions in the 16 videoposters of an online event. We found twice the production of participation in the video-poster modality compared to face-to-face communications, while listing a relevant number of benefits offered by videoposters for the development of online events and professional learning networks.

El éxito del proceso educativo mediados por la tecnología, depende en gran medida de la adopción y el uso de la tecnología digital (TD) por parte del profesorado, desde esta corriente se presenta un diagnóstico multivariado sobre el nivel de adopción y uso de las TD, mediante el efecto moderador de las variables género y edad, el estudio se llevó a cabo con una muestra de 280 docentes universitarios que respondieron el cuestionario denominado TAUT conformado por 46 ítems tipo escala de Likert en 5 dimensiones. La metodología aplicada en el estudio es cuantitativa basada en el método no experimental, descriptivo e inferencial, los datos fueron analizados a partir de una comparación de medias, utilizando pruebas no paramétricas. Los resultados se manifiestan por medio del TAUT autoevaluando la adopción y uso de las TD por parte del profesorado, los mismos que logran poseer una aceptación positiva en todas las dimensiones, como también permiten conocer que no existen diferencias significativas en la mayoría de los ítems en función del género como la edad, los mismos que no afectan a la intención del comportamiento del profesorado para adoptar y usar las TD.

The success of the educational process mediated by technology depends largely on the adoption and use of digital technology (TD) by teachers, from this current a multivariate diagnosis is presented on the level of adoption and use of TD, through the moderating effect of gender and age variables, the study was conducted with a sample of 280 university teachers who responded to the questionnaire called TAUT consisting of 46 Likert scale type items in 5 dimensions. The methodology applied in the study is quantitative based on the non-experimental, descriptive and inferential method, the data were analyzed from a comparison of means, using non-parametric tests. The results are shown by means of the TAUT self-evaluating the adoption and use of the TD by the teaching staff, the same that manage to have a positive acceptance in all the dimensions, as well as allowing to know that there are no significant differences in most of the items according to gender and age, the same that do not affect the intention of the teaching staff behavior to adopt and use the TD.
ADOPTION OF WATER AND SOIL CONSERVATION PRACTICES: THEORETICAL FRAMEWORKS AND ATTITUDINAL COMPONENTS
Authors: FARIDI Amirali , KAVOOSI KALASHAMI Mohammad , EL BILALI Hamid
Published: October 2021

Agricultural production requires two main resources; water, as a source of life, and soil, as a living environment. Water and soil conservation is a critical issue in areas facing water and soil resource constraints. The purpose of this review paper is to provide an overview on the theoretical frameworks used in the analysis of the adoption of water and soil conservation practices. Different models and frameworks have been used in the analysis of the acceptance and/or adoption of new technologies and practices; these include Technology acceptance model, Motivational model, Theory of reasoned action, theory of planned behavior, Innovation diffusion theory and the Unified theory of acceptance and use of technology. The Icek Ajzen’s Theory of Planned Behavior (TPB) has been used as a conceptual framework in many studies on the factors affecting the adoption of water and soil conservation practices. The TPB allows examining the impact of individual factors (i.e. attitude), social norms (cf. subjective norms) and situational factors (i.e. perceived behavioral control) on the adoption of practices. It posits that if a person assesses the suggested behavior as positive (cf. attitude) and if he/she thinks that others want them to perform the behavior (cf. subjective norm), these result in a higher intention and motivation to do so. However, the TPB has some limitations such as not considering environmental/contextual and economic factors that may affect the individual’s intention to perform a behavior. Therefore, despite the widespread use of the TPB model, the paper concludes that the UTAUT seems a better model in understanding the dynamics of acceptance and adoption of water and soil conservation practices.

Protein phosphorylation is a reversible post-translation modification essential in cell signaling. This study addresses a long-standing question as to how the most abundant serine/threonine protein phosphatase 2 (PP2A) holoenzyme, PP2A/B55α, specifically recognizes substrates and presents them to the enzyme active site. Here, we show how the PP2A regulatory subunit B55α recruits p107, a pRB-related tumor suppressor and B55α substrate. Using molecular and cellular approaches, we identified a conserved region 1 (R1, residues 615–626) encompassing the strongest p107 binding site. This enabled us to identify an ‘HxRVxxV619-625’ short linear motif (SLiM) in p107 as necessary for B55α binding and dephosphorylation of the proximal pSer-615 in vitro and in cells. Numerous B55α/PP2A substrates, including TAU, contain a related SLiM C-terminal from a proximal phosphosite, ‘p[ST]-P-x(4,10)-[RK]-V-x-x-[VI]-R.’ Mutation of conserved SLiM residues in TAU dramatically inhibits dephosphorylation by PP2A/B55α, validating its generality. A data-guided computational model details the interaction of residues from the conserved p107 SLiM, the B55α groove, and phosphosite presentation. Altogether, these data provide key insights into PP2A/B55α’s mechanisms of substrate recruitment and active site engagement, and also facilitate identification and validation of new substrates, a key step towards understanding PP2A/B55α’s role in multiple cellular processes.
Learning differentially shapes prefrontal and hippocampal activity during classical conditioning
Authors: Klee Jan L , Souza Bryan C , Battaglia Francesco P
Published: October 2021

The ability to use sensory cues to inform goal-directed actions is a critical component of behavior. To study how sounds guide anticipatory licking during classical conditioning, we employed high-density electrophysiological recordings from the hippocampal CA1 area and the prefrontal cortex (PFC) in mice. CA1 and PFC neurons undergo distinct learning-dependent changes at the single-cell level and maintain representations of cue identity at the population level. In addition, reactivation of task-related neuronal assemblies during hippocampal awake Sharp-Wave Ripples (aSWRs) changed within individual sessions in CA1 and over the course of multiple sessions in PFC. Despite both areas being highly engaged and synchronized during the task, we found no evidence for coordinated single cell or assembly activity during conditioning trials or aSWR. Taken together, our findings support the notion that persistent firing and reactivation of task-related neural activity patterns in CA1 and PFC support learning during classical conditioning.
Finger somatotopy is preserved after tetraplegia but deteriorates over time
Authors: Kikkert Sanne , Pfyffer Dario , Verling Michaela , Freund Patrick , Wenderoth Nicole
Published: October 2021

Previous studies showed reorganised and/or altered activity in the primary sensorimotor cortex after a spinal cord injury (SCI), suggested to reflect abnormal processing. However, little is known about whether somatotopically specific representations can be activated despite reduced or absent afferent hand inputs. In this observational study, we used functional MRI and a (attempted) finger movement task in tetraplegic patients to characterise the somatotopic hand layout in primary somatosensory cortex. We further used structural MRI to assess spared spinal tissue bridges. We found that somatotopic hand representations can be activated through attempted finger movements in the absence of sensory and motor hand functioning, and no spared spinal tissue bridges. Such preserved hand somatotopy could be exploited by rehabilitation approaches that aim to establish new hand-brain functional connections after SCI (e.g. neuroprosthetics). However, over years since SCI the hand representation somatotopy deteriorated, suggesting that somatotopic hand representations are more easily targeted within the first years after SCI.
The inner mechanics of rhodopsin guanylyl cyclase during cGMP-formation revealed by real-time FTIR spectroscopy
Authors: Fischer Paul , Mukherjee Shatanik , Schiewer Enrico , Broser Matthias , Bartl Franz , Hegemann Peter
Published: October 2021

Enzymerhodopsins represent a recently discovered class of rhodopsins which includes histidine kinase rhodopsin, rhodopsin phosphodiesterases, and rhodopsin guanylyl cyclases (RGCs). The regulatory influence of the rhodopsin domain on the enzyme activity is only partially understood and holds the key for a deeper understanding of intra-molecular signaling pathways. Here, we present a UV-Vis and FTIR study about the light-induced dynamics of a RGC from the fungus Catenaria anguillulae, which provides insights into the catalytic process. After the spectroscopic characterization of the late rhodopsin photoproducts, we analyzed truncated variants and revealed the involvement of the cytosolic N-terminus in the structural rearrangements upon photo-activation of the protein. We tracked the catalytic reaction of RGC and the free GC domain independently by UV-light induced release of GTP from the photolabile NPE-GTP substrate. Our results show substrate binding to the dark-adapted RGC and GC alike and reveal differences between the constructs attributable to the regulatory influence of the rhodopsin on the conformation of the binding pocket. By monitoring the phosphate rearrangement during cGMP and pyrophosphate formation in light-activated RGC, we were able to confirm the M state as the active state of the protein. The described setup and experimental design enable real-time monitoring of substrate turnover in light-activated enzymes on a molecular scale, thus opening the pathway to a deeper understanding of enzyme activity and protein-protein interactions.
Different B cell subpopulations show distinct patterns in their IgH repertoire metrics

Published: October 2021

Several human B cell subpopulations are recognised in the peripheral blood, which play distinct roles in the humoral immune response. These cells undergo developmental and maturational changes involving VDJ recombination, somatic hypermutation and class switch recombination, altogether shaping their immunoglobulin heavy chain (IgH) repertoire. Here, we sequenced the IgH repertoire of naïve, marginal zone, switched and plasma cells from 10 healthy adults along with matched unsorted andin silicoseparated CD19+bulk B cells. Using advanced bioinformatic analysis and machine learning, we show that sorted B cell subpopulations are characterised by distinct repertoire characteristics on both the individual sequence and the repertoire level. Sorted subpopulations shared similar repertoire characteristics with their correspondingin silicoseparated subsets. Furthermore, certain IgH repertoire characteristics correlated with the position of the constant region on the IgH locus. Overall, this study provides unprecedented insight over mechanisms of B cell repertoire control in peripherally circulating B cell subpopulations.

In 2019 the University Library at UiT - The Arctic University of Norway partnered with the Arctic Council Indigenous Peoples' Secretariat to create Ságastallamin - Telling the Story of Arctic Indigenous Languages, an interactive multi-media exhibition commemorating the UN International Year of Indigenous Languages. 
An Arctic Indigenous language map was updated for use in the exhibition, but the print format proved to be limiting, and the exhibition time frame did not allow for a thorough linguistic review. Therefore a follow-up project “Arctic Indigenous languages and revitalization: an online educational resource” was started in 2021 to further develop the map and convert it to an openly available online educational resource in GIS format. One key aspect of the new map is that it will feature individual language names in their Indigenous names, as well as in English and Russian. 
The project team consists of representatives from Higher Educational Institutions, Indigenous organizations, and Government departments from Canada, Finland, Greenland, Norway, Russia and the United States. The work on the map has just begun and this spring and summer the goal is to collect feedback from Indigenous language experts on the original exhibition print map before designing a new GIS version in the fall. 
We would like to present the current print map to the Arctic Knot conference in order to receive feedback about additional languages to include, creative ways to present language information in different layers, and suggestions for innovative language revitalization initiatives to feature on the map. There is an online form to collect feedback, and so the lightning talk would be used to present the project goals briefly and then encourage conference participants to submit feedback using the form after the talk.
Multiresolution dendritic cell algorithm for network anomaly detection

Anomaly detection in computer networks is a complex task that requires the distinction of normality and anomaly. Network attack detection in information systems is a constant challenge in computer security research, as information systems provide essential services for enterprises and individuals. The consequences of these attacks could be the access, disclosure, or modification of information, as well as denial of computer services and resources. Intrusion Detection Systems (IDS) are developed as solutions to detect anomalous behavior, such as denial of service, and backdoors. The proposed model was inspired by the behavior of dendritic cells and their interactions with the human immune system, known as Dendritic Cell Algorithm (DCA), and combines the use of Multiresolution Analysis (MRA) Maximal Overlap Discrete Wavelet Transform (MODWT), as well as the segmented deterministic DCA approach (S-dDCA). The proposed approach is a binary classifier that aims to analyze a time-frequency representation of time-series data obtained from high-level network features, in order to classify data as normal or anomalous. The MODWT was used to extract the approximations of two input signal categories at different levels of decomposition, and are used as processing elements for the multi resolution DCA. The model was evaluated using the NSL-KDD, UNSW-NB15, CIC-IDS2017 and CSE-CIC-IDS2018 datasets, containing contemporary network traffic and attacks. The proposed MRA S-dDCA model achieved an accuracy of 97.37%, 99.97%, 99.56%, and 99.75% for the tested datasets, respectively. Comparisons with the DCA and state-of-the-art approaches for network anomaly detection are presented. The proposed approach was able to surpass state-of-the-art approaches with UNSW-NB15 and CSECIC-IDS2018 datasets, whereas the results obtained with the NSL-KDD and CIC-IDS2017 datasets are competitive with machine learning approaches.

Background

Sugarcane (Saccharum spontaneum L.), the major sugar and biofuel feedstock crop, is cultivated mainly by vegetative propagation worldwide due to the infertility of female reproductive organs resulting in the reduction of quality and output of sugar. Deciphering the gene expression profile during ovule development will improve our understanding of the complications underlying sexual reproduction in sugarcane. Optimal reference genes are essential for elucidating the expression pattern of a given gene by quantitative real-time PCR (qRT-PCR).

Method

In this study, based on transcriptome data obtained from sugarcane ovule, eighteen candidate reference genes were identified, cloned, and their expression levels were evaluated across five developmental stages ovule (AC, MMC, Meiosis, Mitosis, and Mature).

Results

Our results indicated that FAB2 and MOR1 were the most stably expressed genes during sugarcane female gametophyte development. Moreover, two genes, cell cycle-related genes REC8 and CDK, were selected, and their feasibility was validated. This study provides important insights into the female gametophyte development of sugarcane and reports novel reference genes for gene expression research on sugarcane sexual reproduction.
Vocal communication in wild chimpanzees: a call rate study
Authors: Crunchant Anne-Sophie , Stewart Fiona A. , Piel Alex K.
Published: October 2021

Background

Patterns of vocal communication have implications for species conservation: a change in calling behaviour can, for instance, reflect a disturbed habitat. More importantly, call rate is a parameter that allows conservation planners to convert call density into animal density, when detecting calls with a passive acoustic monitoring system (PAM).

Methods

We investigated chimpanzee (Pan troglodytes schweinfurthii) call rate during the late dry season in the Issa Valley, western Tanzania by conducting focal follows. We examined the socio-ecological factors that influence call production rate of savanna woodland chimpanzees.

Results

We found that sex, proportion of time spent in a vegetation type, proportion of time spent travelling, time of the day, party size and swollen parous female presence had a significant effect on the call rate. Call rate differed among the different demographic classes with subadult and adult males vocalising twice as often as the subadult and adult females and three times as often as the juveniles.

Applications

The use of PAM and recent statistical developments to estimate animal density is promising but relies on our knowing individual call rate, often not available for many species. With the improvement in automatic call detection, we anticipate that PAM will increasingly be broadly applied to primates but also across taxa, for conservation.

In India, agriculture and related industries constitute the most important source of income. Around 120 million small-scale farmers play an important role in the country's food supply system. People's knowledge, attitudes, and practices regarding any contagious disease, such as COVID-19, all play a role in determining a society's willingness to accept behavioural change strategies aimed at disease prevention. The majority of respondents (35.00 percent) are between the ages of 35 to 45, with 77 of the total respondents belonging to the OBC categories. The majority of respondents' educational levels were indicated as high school (49.17 percent). The findings of this study revealed that there was a high level of awareness, particularly among farm women, about the nature of disease, its symptoms, and the preventive actions that should be followed to prevent disease transmission. COVID-19 is a contagious disease caused by a virus, according to the majority of respondents (79.17%), and respiratory droplets are the virus's primary method of transmission, according to 75.00 percent of respondents. Farmers should bring their own food and water from home to their agricultural field, as well as soap and water, according to all of the respondents (81.67 percent). Besides, 73.34 percent of respondents believe that wearing a mask and maintaining social distance are necessary during agricultural tasks. COVID- 19 has also had an impact on agriculture. Farm women faced many constraints during this period. Out of which it is difficult to get agricultural inputs, animal feed and vaccines, lack of outside traders for product procurement, lack of technical experts to fix the problem in time, ignorance about government programs during the lockdown.

Published: October 2021

In this paper, we propose a three-parameter probability distribution called equilibrium renewal Burr XII distribution using the equilibrium renewal process. The statistical properties of the distribution such as moment, mean deviation, order statistics, moment generating function, Beforroni and Lorenz curve, survival function, reversed hazard rate and hazard function were derived. The method of maximum likelihood is used for estimating the distribution's parameters and a simulation study is conducted to assess the performance of the parameters. We provide two applications in eld of health to demonstrate the importance of the proposed distribution.
