Beam Splitting Planar Inverted F Antenna For 5G Communication
Authors: Verma Akhilesh , Srinivasa Raghava Nallanthighal
Published: October 2021

A planar inverted-F antenna with symmetrical split beams and loaded with radio frequency absorbers (here Eccosorb MCS) for 5G communication is proposed. The multi-beam antennas reduce the requirement of number of antennas and provide wide coverage. But they require a complex system such as a phased array or MIMO antennas. On the other hand, multi-beam antennas do not have such requirements. In this work, we propose a PIFA antenna which achieves multi-beam behaviour by six slabs of absorbers placed periodically between the PIFA patch and substrate to split the beams into two directions at +26°. The proposed antenna obtains a frequency band of 24.2- 25.7 GHz and achieves a high gain of approximately 10 dB at +26°. The performance of the proposed antenna is suitable for G communication. All simulations of the antenna are carried out using Ansys HFSS. The design was validated by simulations and later confirmed with measurements.
Los niños y la familia: entre el imaginario y la separación
Authors: Medina Gómez Manuela , Giraldo Marín Daniela , Posada Castaño Nataly
Published: October 2021

Este artículo, resultado de investigación, comprende los imaginarios de familia que construyen los niños, antes y después de la separación de los padres. La metodología respondió a un paradigma cualitativo, bajo un enfoque hermenéutico, privilegiándose la narrativa como estrategia. La población estuvo compuesta por 6 niños del grado tercero y sus respectivas madres. Los resultados indican que el imaginario de familia se transforma después de la separación y que los cambios que sufre la dinámica familiar inciden en este. Se concluye que después de la ruptura de los padres, todos los miembros de la familia buscan establecer vínculos con otras personas, familia, amigos o grupos sociales para afrontar las dificultades que supone este cambio; y los padres esperan recibir apoyo de la escuela para reducir el impacto de la separación en la vida de los niños.

W okowach mitów – "Medeamaterial" Heinera Müllera, Pascala Dusapina i Sashy Waltz
Authors: Książek Paulina
Published: October 2021

Pascal Dusapin is regarded as one of the outstanding contemporary French composers. The opera genre seems to have a special place among his creative achievements. Medeamaterial is the composer’s second work for the stage, and one of many where myth becomes the subject. As the text of the libretto, he chose a text by a German dramatist, Heiner Müller. Both authors decide to reinterpret an antique history and deconstruct it using the means available to them. As does Sasha Waltz, who in 2007 staged Dusapin’s work. All three, while initiating a dialogue with the past, set the work firmly in the present. In this article the author attempts to answer the question how the devices used by these creative artists shape the psychological portrait of the drama’s heroine.
How to design robust algorithms using noisy comparison Oracle
Authors: Addanki Raghavendra , Galhotra Sainyam , Saha Barna
Published: October 2021

Metric based comparison operations such as finding maximum, nearest and farthest neighbor are fundamental to studying various clustering techniques such as
k
-center clustering and agglomerative hierarchical clustering. These techniques crucially rely on accurate estimation of pairwise distance between records. However, computing exact features of the records, and their pairwise distances is often challenging, and sometimes not possible. We circumvent this challenge by leveraging weak supervision in the form of a comparison oracle that compares the relative distance between the queried points such as `Is point
u
closer to
v
or
w
closer to
x
?'.

However, it is possible that some queries are easier to answer than others using a comparison oracle. We capture this by introducing two different noise models called adversarial and probabilistic noise. In this paper, we study various problems that include finding maximum, nearest/farthest neighbor search under these noise models. Building upon the techniques we develop for these problems, we give robust algorithms for
k
-center clustering and agglomerative hierarchical clustering. We prove that our algorithms achieve good approximation guarantees with a high probability and analyze their query complexity. We evaluate the effectiveness and efficiency of our techniques empirically on various real-world datasets.

Given a set
V
, the problem of
unconstrained submodular maximization with modular costs (USM-MC)
asks for a subset
S
⊆
V
that maximizes
f
(
S
) -
c
(
S
), where
f
is a non-negative, monotone, and submodular function that gauges the utility of
S
, and
c
is a non-negative and modular function that measures the cost of
S.
This problem finds applications in numerous practical scenarios, such as profit maximization in viral marketing on social media.

This paper presents ROI-Greedy, a polynomial time algorithm for USM-MC that returns a solution
S
satisfying [EQUATION], where
S

is the optimal solution to USM-MC. To our knowledge, ROI-Greedy is the first algorithm that provides such a strong approximation guarantee. In addition, we show that this worst-case guarantee is
tight
, in the sense that no polynomial time algorithm can ensure [EQUATION], for any ϵ > 0. Further, we devise a non-trivial extension of ROI-Greedy to solve the profit maximization problem, where the precise value of
f
(
S
) for any set
S
is unknown and can only be approximated via sampling. Extensive experiments on benchmark datasets demonstrate that ROI-Greedy significantly outperforms competing methods in terms of the tradeoff between efficiency and solution quality.
Data acquisition for improving machine learning models
Authors: Li Yifan , Yu Xiaohui , Koudas Nick
Published: October 2021

The vast advances in Machine Learning (ML) over the last ten years have been powered by the availability of suitably prepared data for training purposes. The future of ML-enabled enterprise hinges on data. As such, there is already a vibrant market offering data annotation services to tailor sophisticated ML models.

In this paper, inspired by the recent vision of online data markets and associated market designs, we present research on the practical problem of obtaining data in order to improve the accuracy of ML models. We consider an environment in which consumers query for data to enhance the accuracy of their models and data providers who possess data make them available for training purposes. We first formalize this interaction process laying out the suitable framework and associated parameters for data exchange. We then propose two data acquisition strategies that consider a trade-off betweenexplorationduring which we obtain data to learn about the distribution of a provider's data andexploitationduring which we optimize our data inquiries utilizing the gained knowledge. In the first strategy,Estimation and Allocation(EA), we utilize queries to estimate the utilities of various predicates while learning about the distribution of the provider's data; then we proceed to the allocation stage in which we utilize those learned utility estimates to inform our data acquisition decisions. The second algorithmic proposal, namedSequential Predicate Selection(SPS), utilizes a sampling strategy to explore the distribution of the provider's data, adaptively investing more resources to parts of the data space that are statistically more promising to improve overall model accuracy.

We present a detailed experimental evaluation of our proposals utilizing a variety of ML models and associated real data sets exploring all applicable parameters of interest. Our results demonstrate the relative benefits of the proposed algorithms. Depending on the models trained and the associated learning tasks we identify trade-offs and highlight the relative benefits of each algorithm to further optimize model accuracy.

Mechanical properties of wire arc additive manufactured carbon steel cylindrical component made by gas metal arc welding process
Authors: Nagasai Bellamkonda Prasanna , Malarvizhi Sudersanan , Balasubramanian Visvalingam
Published: October 2021

Wire arc additive manufacturing (WAAM), a welding-based additive manufacturing (AM) method, is a hot topic of research since it allows for the cost-effective fabrication of large-scale metal components at relatively high deposition rates. In the present study, the cylindrical component of low carbon steel (ER70S-6) was built by WAAM technique, using a GMAW torch that was translated by an automated three-axis motion system using a rotation table. The mechanical properties of the component were evaluated by extracting tensile, impact toughness and hardness specimens from the two regions of the building up (vertical) direction. It is found that the tensile properties of the built material exhibited anisotropic characteristics. The yield strength and ultimate tensile strength varied from 333 to 350 MPa and from 429 to 446 MPa, respectively, (less than 5 % variation).
Covering China’s New Development Pattern: Issues and Strategies for Transcultural Communication
Authors: Hang Min , Xiang Qiren , Li Dongxiao
Published: October 2021

The profound integration of China’s economy into the global economic and trade system creates an open cultural environment that facilitates cooperation and exchanges between China and the outside world. It is essential to understand how media with diverse cultural backgrounds cover China’s new development pattern and how they narrate China’s economic development in the global community. This essay examines the above issues from three perspectives: policy narrative, system narrative, and identity narrative. The diverse narratives provide implications for us to understand China’s economic policy in the global context, and to pursue new insights into transcultural communication.
Local nonlinearity engineering of evanescent-field-interaction fiber devices embedding in black phosphorus quantum dots

Published: October 2021

Tapered fiber (TF) and D-shaped fiber (DF) are two types of widely investigated devices in facilitating evanescent-field interactions with external materials. Although they have been found to be particularly useful in various ultrafast regimes, to date there is still no clear or systematic investigation on their local nonlinearities as well as the exerted influences on ultrafast behaviors. Herein, we present such thorough investigation through local nonlinearity engineering on TF and then in contrast with a DF as a reference. Optically deposited black phosphorus quantum dots (BPQDs) are used for saturable absorption. The nanometer-scale extremely small sizes of the BPQDs helpfully eliminate size-induced uncertainties or distortions during both device fabrication and the latter light–matter interaction. For the TF, in the experiment, it is found that the local nonlinear effect starts to be rather appreciable as the TF shrinks to a moderate thickness. Remarkably in comparison, the local nonlinearity of the DF itself can even be neglected reasonably, but after coating with BPQDs, it possesses a much larger modulation depth than any of the used BPQDs-coated TFs with different thicknesses/lengths. Further, we theoretically analyze the related locally nonlinear effects and reveal, for the first time, the direct origin of saturable absorption with evanescent-field-based general structures.

Published: October 2021

The clean production and washing resistance of nano-coating have always been common issues in nano-functional polyester textiles because of the dense structure and chemically inert surface. Here, we developed a clean treatment strategy for preparing washable silver nanoparticle (AgNP)-coated polyester fibers through high-temperature, high-pressure hydrothermal self-assembly of AgNPs in polyester fibers. AgNPs with high affinity to polyester were prepared through the hydrothermal reduction of AgNO3 by hyperbranched poly(amide-amine)s. The as-prepared spherical AgNPs possessed a uniform particle size (∼7.52 nm), a positive charge (zeta potential of +54.52 mV), and good dispersibility and chemical stability at 110–130°C. The optimal clean treatment conditions had Ag concentrations of 1–50 mg/L, impregnation time of 2 h, and impregnation temperature of 110°C. Therefore, the Ag content of polyester fibers in the range 0–2,500 mg/kg could be precisely controlled. The as-prepared polyester fibers exhibited excellent antibacterial activities and washing resistance and low Ag release (0.00024% for 24 h). Even when the Ag content was as low as ∼50 mg/kg, the corresponding bactericidal rates increased to 99.99% for Escherichia coli and 99.93% for Staphylococcus aureus. The sample containing ∼200 mg/kg of Ag could achieve up to a 99.99% bactericidal rate for E. coli and 99.9% for S. aureus even after 50 standard washes.
Psephological Advancements and Pitfalls of Political Opinion Polls in India
Authors: Rai Praveen
Published: October 2021

Political opinion polls in India are holistic snapshots in time that divulge deep dive information on electoral participation, ideological orientation and self-efficacy of the electorate and faith in core democratic values. The popularity of election surveys stems from the political socialization and crystal ball gazing curiosity of the citizens to foresee the outcomes of the hustings before the pronouncement of formal results. The opinion polls provide crucial data on voting behaviour and attitudes, testing theories of electoral politics and domain knowledge production. The obsession of the Indian media with political forecasting has shifted the focus from psephology to electoral prophecy, but it continues to furnish the best telescopic view of elections based on the feedback of the electorate. The ascertainment of subaltern opinion by surveys not only broadens the contours of understanding electoral democracy, but also provides an empirical alternative to elitist viewpoint of competitive politics in India.
The duration of word-final /s/ differs across morphological categories in English: evidence from pseudowords
Authors: Schmitz Dominic , Baer-Henney Dinah , Plag Ingo
Published: October 2021

Previous research suggests that different types of word-final /s/ and /z/ (e.g. non-morphemic vs. plural or clitic morpheme) in English show realisational differences in duration. However, there is disagreement on the nature of these differences, as experimental studies have provided evidence for durational differences of the opposite direction as results from corpus studies (i.e. non-morphemic > plural > clitic /s/). The experimental study reported here focuses on four types of word-final /s/ in English, i.e. non-morphemic, plural, andis- andhas-clitic /s/. We conducted a pseudoword production study with native speakers of Southern British English. The results show that non-morphemic /s/ is significantly longer than plural /s/, which in turn is longer than clitic /s/, while there is no durational difference between the two clitics. This aligns with previous corpus rather than experimental studies. Thus, the morphological category of a word-final /s/ appears to be a robust predictor for its phonetic realisation influencing speech production in such a way that systematic subphonemic differences arise. This finding calls for revisions of current models of speech production in which morphology plays no role in later stages of production.
Global and Regional Damages in Retinal Ganglion Cell Axon Bundles Monitored Non-Invasively by Visible-Light Optical Coherence Tomography Fibergraphy

Published: October 2021

Retinal ganglion cells (RGCs) exhibit compartmentalized organization, receiving synaptic inputs through their dendrites and transmitting visual information from the retina to the brain through the optic nerve. Little is known about the structure of RGC axon bundles extending from individual RGC somas to the optic nerve head (ONH) and how they respond to disease insults. We recently introduced visible-light optical coherence tomography fibergraphy (vis-OCTF), a technique for directly visualizing and analyzing mouse RGC axon bundlesin vivo. In this study, we validated vis-OCTF's ability to quantify RGC axon bundles with an increased number of RGCs using mice deficient in BCL2-associated X protein (BAX−/−). Next, we performed optic nerve crush (ONC) injury on wild-type (WT) mice and showed that the changes in RGC axon bundle width and thickness were location-dependent. Our work demonstrates the potential of vis-OCTF to longitudinally quantify and track RGC damage at single axon bundle level in optic neuropathies.

SIGNIFICANCE STATEMENTNearly all clinical and preclinical studies measure the retinal nerve fiber (RNFL) thickness as the sole indicator of retinal ganglion cell (RGC) damage without investigating RGC axon bundles directly. We demonstrated visible-light optical coherence tomography fibergraphy (vis-OCTF) to directly quantify global and regional RGC axon bundle organizationsin vivoas a new biomarker for RGC health. We validatedin vivovis-OCTF measures using both confocal microscopy of the immunostained flat-mounted retina and numerical simulations. Vis-OCTF for monitoring RGC axon bundle organization has the potential to bring new insight into RGC damage in optic neuropathies.

Mixed lineage kinase domain‐like (MLKL) is the executioner in the caspase‐independent form of programmed cell death called necroptosis. Receptor‐interacting serine/threonine protein kinase 3 (RIPK3) phosphorylates MLKL, triggering MLKL oligomerization, membrane translocation and membrane disruption. MLKL also undergoes ubiquitylation during necroptosis, yet neither the mechanism nor the significance of this event has been demonstrated. Here, we show that necroptosis‐specific multi‐mono‐ubiquitylation of MLKL occurs following its activation and oligomerization. Ubiquitylated MLKL accumulates in a digitonin‐insoluble cell fraction comprising organellar and plasma membranes and protein aggregates. Appearance of this ubiquitylated MLKL form can be reduced by expression of a plasma membrane‐located deubiquitylating enzyme. Oligomerization‐induced MLKL ubiquitylation occurs on at least four separate lysine residues and correlates with its proteasome‐ and lysosome‐dependent turnover. Using a MLKL‐DUB fusion strategy, we show that constitutive removal of ubiquitin from MLKL licences MLKL auto‐activation independent of necroptosis signalling in mouse and human cells. Therefore, in addition to the role of ubiquitylation in the kinetic regulation of MLKL‐induced death following an exogenous necroptotic stimulus, it also contributes to restraining basal levels of activated MLKL to avoid unwanted cell death.
Desarrollo del concepto de libertad en la Filosofía del derecho: exégesis y eiségesis en el contexto de la diferenciación del capital
Authors: Montero Christian
Published: October 2021

En el presente artículo nos concentramos en desarrollar lo que nos figuramos como los pasajes esenciales de la filosofía política de Hegel en la Filosofía del Derecho. En primer lugar, como nota introductoria al contenido analizamos brevemente los fines que persigue su proyecto, tanto contextualmente como en sí mismo. Esto nos obliga a distinguir entre lo existente y lo real. En segundo lugar, procedemos a exponer el concepto de voluntad, que transita desde un momento abstracto (la voluntad subjetiva) hacia el momento concreto (la voluntad en sí y para sí, que es idéntica a la Idea). En tercer lugar, proseguimos estudiando la moralidad enfocándonos en la crítica inmanente que Hegel realiza a Kant fundamentando la idea de autonomía del ser moral en la Sittlichkeit. En cuarto lugar, la Idea ética continúa dándose contenido en la familia, la sociedad civil y el Estado. Nuestro interés se centró en los dos últimos, aunque la familia tiene su exiguo lugar en el artículo. El énfasis en la sociedad civil y el Estado reside en los momentos en que la individualidad experimenta sus fines egoístas y, posteriormente universales. Por último, reflexionamos acerca de nuestra contemporaneidad y de las exigencias que supone el concepto de eticidad en un contexto nuevo, a saber, la diferenciación de la mercancía que deviene en la diferenciación del capital. Esta tarea, lejos de distanciarnos del concepto de Hegel nos invita a retomarlo para distinguir sus límites como su potencialidad.
Hegel y las lógicas del castigo
Authors: Peinado Andújar Carmen
Published: October 2021

A pesar de haber sido formulada de la manera más completa hace casi dos siglos, la teoría hegeliana de la pena sigue siendo convincente por entender la justicia en términos de reconocimiento y no en una clave vengativa o correctiva. El problema ante el que nos encontramos se puede resumir en el sintagma de “justificación de la pena”. Lo más radicalmente novedoso en la filosofía de Hegel es que la pena, tal y como se muestra en el parágrafo 100 de los Principios de Filosofía del Derecho, es considerada como “un derecho” del delincuente. Así, la pena impuesta a la persona que decide delinquir no resultaría ser nada más que un reconocimiento a su racionalidad. Esto es así puesto que, a ojos de Hegel, de no tratarse de un ser racional, sería incoherente castigarle. Encontramos entonces una relación directa entre el castigo y una determinada concepción de la racionalidad que, como es conocido, para Hegel está relacionada con la libertad y su desarrollo en la historia. Esta concepción tiene sus dificultades, a las cuales trataremos de aproximarnos: ¿cómo puede ser algo simultáneamente un derecho y un castigo para la misma persona? En la primera parte de este artículo dibujaremos la teoría de la pena de Hegel como una que no debe ni reformar al individuo ni vengar el daño. Esto nos permite pensar la justicia en términos que dejan atrás tanto la venganza como la corrección. Una lectura de Hegel nos llevaría hoy a adoptar una perspectiva de un gran compromiso moral, que no patologice al criminal sólo por ser criminal, y que, a un mismo tiempo, no criminalice eternamente al culpable. Estamos insertos en un marco complejo de relaciones sociales donde es imposible no actuar mal a ojos de alguien. No por ello nos debemos quedar en la inacción, pues, ¿de qué serviría la autonomía para pensar la moral, si no la tenemos para actuar conforme a ella? Legislación y moral no se pueden entender completamente si prescindimos de uno de los dos términos. Por ello, en la segunda parte del trabajo se tratará de analizar este problema en clave ética, subrayando la crítica de Hegel al formalismo kantiano y al alma bella.
La crítica del joven Marx a Hegel. El Manuscrito de Kreuznach.
Authors: Moreno Tonda Daniel
Published: October 2021

La Crítica a la filosofía del estado de Hegel es un texto de importancia capital para el desarrollo filosófico-político de Marx donde critica a la Filosofía del derecho de Hegel. El articulo abordará tres temas principales: 1) Marx articula su crítica aplicando conceptos e ideas propias de los jóvenes hegelianos, especialmente de Feuerbach con su crítica de la inversión de sujeto y objeto, esto es, la Idea en Hegel es el sujeto y los objetos sus predicados. En la lectura de este borrador inacabado ya se deja entrever los cimientos de la reformulación metodológica entre Hegel y Marx. Sin embargo, esta crítica en muchos casos parte de una visión de Hegel y su teoría ciertamente limitada; 2) Hegel era bien consciente de los nuevos retos que presentaba la incipiente sociedad moderna y orientó su filosofía política a desvelar las contradicciones y ponerles solución bajo el Estado. No obstante, Marx apuntará que Hegel no es capaz de armonizar las particularidades de la sociedad civil y que eventualmente la propiedad privada acaba determinando al Estado; 3) Al desterrar de la centralidad la Idea y su encarnación en el Estado hegeliano, Marx, con Feuerbach, propone poner en su lugar al ser humano, de manera que la realización de su esencia política ya no será bajo el Estado monárquico constitucional sino en un Estado democrático y republicano. El articulo pretende dar cuenta de la amplitud de la critica de Marx y, en última instancia, de ponerlo en conexión con las recientes corrientes del “New Hegelian Marxism” destacando la importancia de este manuscrito.

Allelopathic potential and cytostatic activity of Antarctic moss Sanionia georgicouncinata (Amblystegiaceae)
Authors: Dziuba O. , Liubinska A. , Khoyetskyy P. , Bedernichek T.
Published: October 2021

From the first half of the XX century, the maritime Antarctic was a region with high regional warming rates. At the beginning of the XXI century, regional warming strongly slowed down, but during the next twenty years the near-surface temperatures and mean annual precipitation at the Antarctic Peninsula will most probably increase. Higher temperatures and precipitation make the conditions in the maritime Antarctic more favourable for plants, including invasive species. Moreover, the increasing number of Antarctic tourists unintentionally transport thousands of seeds to the Antarctic on their clothes and equipment. In such circumstances, it is important to evaluate possible defensive mechanisms of native plant species, including their allelopathic potential. The objective of this study was to evaluate the allelopathic potential and cytostatic activity of Sanionia georgicouncinata. This species is widespread in the maritime Antarctic and is one of the most abundant moss species on the Argentine Islands (Wilhelm Archipelago). Seeds of cucumber Cucumis sativus, radish Raphanus raphanistrum subsp. sativus, wheat Triticum vulgare, and amaranth Amaranthus paniculatus were used as bioassay species. Fresh green biomass of S. georgicouncinata was used to prepare aqueous extracts with 1 : 10, 1 : 50, and 1 : 100 plant to water ratios. The average root length of wheat sprouts and cucumber sprouts in distilled water did not differ significantly from those in plant extracts. The root length of radish sprouts in 1 : 50 plant extract was significantly shorter than in distilled water. Meanwhile, in 1 : 50 and 1 : 100 water extracts, roots of amaranth plants were significantly longer than in water. The number of lateral roots of cucumber sprouts in water and studied aqueous extracts varied from 1 to 6 with medians from 3 to 4. The medians of control (distilled water) and sample groups (aqueous extracts) did not differ significantly, but only 38.1 ± 6.1% of cucumber sprouts developed lateral roots in the 1 : 10 aqueous extract of S. georgicouncinata, and even less – 28.3 ± 7.5% in the 1 : 50 aqueous extract. The results of this study show that the allelopathic potential of S. georgicouncinata is low. However, a significant cytostatic activity of the studied extracts shows that this species may still affect other plants and animals. Further research is needed to evaluate the impact of the studied extracts on root growth and germination of the invasive plants, particularly Poa annua.
Gender and Memory in Cristina García's The Agüero Sisters
Authors: Mertová Anna
Published: October 2021

This paper discusses Cristina García’s 1997 novel The Agüero Sisters. Its aim is to outline some of the topics present in the novel through the lens of gender, and to contribute to an awareness of Hispanic American literature. Following a brief introduction, the paper discusses masculinity and femininity as present in the novel. Here the paper focuses on two motifs – the position of the human body in the novel, and memory; a link between these two motifs is suggested. Memory is central to the novel, and it appears in different variations throughout the text – nostalgia, intergenerational memory, or memory as an inherently unreliable process. While this paper does not exhaust the topic of memory, it attempts to point out a possible direction for further discussion.
When Nature Triggers Trauma: Environmental Racism and Ecofeminism in Zora Neale Hurston's Their Eyes Were Watching God
Authors: Rohová Karla
Published: October 2021

This paper deals with the depiction of environmental racism, natural trauma and the woman/nature or woman/animal relationships in Zora Neale Hurston’s novel Their Eyes Were Watching God. The main goal is to identify and critically evaluate the impacts of such depictions or relationships in the context of the systemic oppression of African American women and men in the United States of America. For this purpose, excerpts from throughout the novel are discussed with regard to their depiction of dehumanization, animalization, natural trauma, or the metaphor of the female body, with the emphasis on ecofeminist and ecocritical aspects in Hurston’s work
“Quem matou a senhora batata?”: possibilitando a aprendizagem em genética por meio de uma sequência de ensino investigativa
Authors: Peruch Junior Weligton José , Borges Corte Viviana , Araújo Michell Pedruzzi Mendes
Published: October 2021

A compreensão de conceitos de genética, dos genes e da molécula do DNA são de grande importância para a formação dos conhecimentos consolidados pelos estudantes sobre a estruturação da vida.  Entretanto, a aprendizagem de genética é, por vezes, tida como desafiadora devido à terminologia específica e aos conceitos abstratos, resultando em dificuldades dos estudantes na aprendizagem desse conteúdo curricular. Nesse sentido, buscar novas estratégias de abordagem pode favorecer uma experiência mais dinâmica e motivadora, tendo em vista a promoção da autonomia dos estudantes. Para isso, apresentamos uma proposta de intervenção pedagógica, que se configura como uma Sequência de Ensino Investigativa (SEI), alicerçada metodológica e teoricamente nos pressupostos de Carvalho (2013), que utiliza como gatilho motivador uma atividade investigativa criminal fictícia, traçando paralelos entre o contexto real e a educação científica. Como resultado, destaca-se que a presente SEI pode potencializar os processos de ensino e aprendizagem de genética, tornando as aulas mais contextualizadas e significativas em prol do engajamento e valorização do protagonismo dos discentes.

Published: October 2021

O artigo aborda as contribuições do agente conversacional/chatbot/tutor virtual no ensino e aprendizagem dos conteúdos da Física. O chatbot é um programa que simula um diálogo entre o homem e um robô em linguagem natural. A pesquisa bibliográfica contempla estudos internacionais e nacionais, mediado pela busca das palavras-chave: (chatbot, education, high school, physics); com recorte temporal de 2016-2020, utilizou-se 08 artigos que atendiam aos critérios de inclusão. Os benefícios para aprendizagem compõem-se: estabelecimento de uma metodologia ativa de ensino, proposição de mais um “espaço virtual” para receber feedback; capacidade de simular experimentos, proporcionando uma alternativa à escassez de laboratórios de Ciências. O agente conversacional, comparado a outros métodos pedagógicos, demonstra-se superior à leitura de um livro sobre os mesmos conteúdos, em tempos iguais. A evolução na aprendizagem foi equivalente em pesquisas relacionando o tutor virtual e tutores humanos, prevalecendo  os tutores humanos em situações de esclarecimento de dúvidas.
From Essence to Queery—Puzzling Over the Persistence of Identity
Authors: Simmons K. Merinda , Posadas Jeremy
Published: October 2021

The following conversation between K. Merinda Simmons (University of Alabama) and Jeremy Posadas (Austin College) is an outgrowth of a roundtable on class, identity, and religion presented as part of the North American Association for the Study of Religion (NAASR) meeting in November 2020. That discussion reflected participants’ respective approaches and research emphases, of course, but we all in one way or another focused our comments on the role of intersectionality (i.e., the approach to identity that sees social categories and systems of discrimination as structurally interconnected) within the academic study of religion. Using that theme as a starting point, the back-and-forth that follows brings our respective work in gender studies and queer theory into the mix. While exchanging the messages that became this text, we purposefully took an approach of “thinking out loud” and experimenting with ideas in formative stages. This embrace of what remains unsettled—in fact, the process of unsettling what scholars often take to be terra firma—is reflected in our tone and in our relative disinterest in structural linearity. We hope instead that this conversation might be read as exactly that: a conversation, necessarily partial and productively unfinished.
El papel de los afectos en la acción humana: una exégesis de «S. Th.», I-II, q. 28, a. 6
Authors: Pérez-Soba-Díez-del-Corral Juan-José
Published: October 2021

Para comprender mejor el papel de los afectos en la acción humana hay que revisar la enseñanza de Santo Tomás y el sentido analógico que concede al amor. Así se puede verificar una integración de la fuente aristotélica que distingue las potencias humanas, con la dionisiaca más centrada en el aspecto unitivo del amor. De aquí se comprueba la necesaria mediación afectiva del amor en toda acción humana como integración de la tendencia natural y la intencionalidad propia de la razón práctica. Este es el contenido real de la S. Th., I-II, q 28, a. 6, que tiene una importancia decisiva para entender el valor moral de las acciones humanas.

La fe vista desde la experiencia estética según el «Directorio para la Catequesis» (2020)
Authors: Persidok Andrzej
Published: October 2021

El presente estudio parte del análisis del nuevo Directorio para la Catequesis, fijando la atención en el concepto de la experiencia cristiana. El objeto de interés particular es la visión «estética» de dicha experiencia. El Directorio varias veces habla de la belleza del Evangelio, la belleza de Dios o la belleza de Cristo. Todas estas menciones parecen más que unas meras metáforas. Se trata, más bien, de una nueva manera de presentar a la fe cristiana, que sea más adecuada a la sensibilidad del hombre contemporáneo. Después de analizar el texto del documento, se exponen las raíces teológicas del lenguaje estético presente en él y se propone un intento de evaluación de ventajas y peligros del acercamiento estético al tema de la fe.

Relevance. The spread of the coronavirus infection and the ensuing economic restrictions significantly influenced the main parameters of the socio-economic development of Russia and its territories, affecting the growth rate, production structure, territorial differentiation and competitiveness of Russian regions. Purpose of the study. The key goal of the study was to identify the socio-economic changes in the development of the country and its regions during the pandemic. Data and Methods. The analysis relies on open data on the socio-economic development of Russian regions for 2019–2021 (monthly, quarterly and annual periods), posted on the official website of Rosstat. Methodologically, the study is based on the comparative analysis of the data for the federal districts and their regions. Results. The study describes the main trends in the development of industry, trade, paid services, and investment potential and in the dynamics of unemployment and income in federal districts and regions. The first wave hit Russian regions the hardest due to the rigorous restrictions. Although no sharp recession was detected during the second wave, the stagnation in the key sectors persisted. The third wave is expected to have the same impact as the second. Conclusions. After the second wave subsided, there was a revival of economic activity in the spring of 2021. However, this has not turned into a steady trend yet. The coronavirus pandemic affected the competitiveness of regions. The importance of certain factors (including those related to resource potential) decreased during the pandemic, while the role of the competitive position of regions in the distribution of federal budget transfers increased.

Relevance. The coronavirus pandemic has lead to one of the most serious crises in the global economy. The significant disparities between Russian regions influenced the levels of morbidity and their strategies of containing the crisis. Research objective. The aim of this paper is to identify the factors of regional development which, during the pandemic and in the post-pandemic period, affected and will affect the economic stability of Russian regions. Materials and Methods. The research is based on the Rosstat data, industry reviews, materials from analytical and consulting firms, Russian and international research literature. The research methodology is based on the structuralist approach and the provisions of the new structural economics put forward by J. Lin. The methods of comparative, statistical, and structural analysis were also used. Results. The most significant factors in regional economic development are the structure of the economy and the quality of public administration at the national and regional levels. The high-tech sector in the structure of a regional economy plays a pivotal role in ensuring its stability in the times of crisis. The study shows the need for a transition to independent national value chains. It is also necessary to develop a long-term national strategy aimed at stimulating the structural transformation of regional economies. Conclusions. The study has demonstrated the importance of the two key factors in shaping the regions’ responses to the pandemic and the speed of their recovery – the structure of regional economy and the role of the government. These factors should be taken into account by the Strategy of the State Regional Industrial Policy.

Chasing Shadows
Authors: Canals Roger
Published: October 2021

“Chasing Shadows” offers an intimate portrait of the current practice of the prophetic movement called Kyangyang in Guinea-Bissau. Kyangyang means “the shadows”, but its followers also call themselves “Children of God”. The members of the movement, belonging to the Balanta ethnic group, communicate with their ancestors, who transmit messages from the high God through prophetic writing, glossolalia, divination rituals, and spirit possession. Guided by the ancestors, they heal and give advice in collective ceremonies. This film delves into the creative and poetic world of Kyangyang by giving voice to its members, young and adults, men and women. It also explores the relations between Kyangyang and Balanta cosmology and between the prophetic movement and the two main "world religions" in the country: Islam and Christianity, in its Catholic and Evangelical modes.

Saberes e Práticas Organizativas das Culturas Populares na cidade de Caruaru, Pernambuco, Brasil
Authors: Santos Elisabeth Cavalcante dos , Silva Ítalo Henrique de Freitas Ramos da , Dias Pâmela Karolina , Morais Wilson Mike
Published: October 2021

Abstract This paper examines the embodied practical knowledge (know-how) that make up the organizational practices of popular cultures in the northeast Brazilian municipality of Caruaru, located in the microzone of Agreste in the state of Pernambuco. We held informal and semi-structured interviews with fifteen masters and artists from Caruaru, linked to eleven different popular culture segments, and performed non-participant observation in workshops, meetings, and forums. Our discussion reflects on the ancestries, affections between family members, masters and apprentices, explicit rules, conflicts, and distinctions constituting the popular know-how that underlies organizational practices. We highlight as the main contributions of this study to Organizational Studies: the production of authentic knowledge about organizing practiced in peripheral contexts; and the questioning of the distinction between ‘knowing’ and ‘doing’ and instrumental rationality as the basis for organizational practices. Finally, we point out how practice theory initiates a wider discussion about popular cultures in a peripheral context like the Agreste of Pernambuco, which includes the contribution of other perspectives and leads to concrete actions in practice.
