The Relationships between Metacognition and Reading Strategies: The Case of English-Majored Students at a Private University in Vietnam
Authors: Nguyen Chi Hong , Phung Vy Trieu
Published: July 2021

Many studies have pointed out a proportionate relation between metacognition and reading strategies. This study advances such an understanding by arguing that this relation is comprised of several sub-relations. Metacognitive Awareness Inventory and Reading Strategies Inventory were conducted among 92 English as Foreign Language students at a Vietnamese university. This study highlights 3 major findings. First, metacognition processes do not merely mean “cognition about cognition”. Second, while previous studies tended to portray metacognition as a whole, it is argued in this study that it is constituted by two main clusters (knowledge of cognition and regulation of cognition) which can be further specified into eight sub-components. Third, there seem to be some sub-linearities that underpin students’ metacognition and that influence their uses of reading strategies. These findings are hoped to shed light on preserving spaces and autonomy in curriculum/syllabus development for students to exercise their own metacognition.

Published: July 2021

El presente trabajo da cuenta de las movilizaciones para pedir justicia por el asesinato de Giovanni López que se suscitaron durante la primera quincena de junio del año 2020 en la ciudad de Guadalajara, Jalisco, México. Estas movilizaciones son un referente contemporáneo del uso de la fuerza policial por parte del Estado mexicano y se incluye dentro de los pocos movimientos sociales que han irrumpido durante el lapso de la pandemia del Covid 19.El sostén teórico de este artículo parte de la acción colectiva, las formas organizativas y las emociones, en medida que consideramos que estas últimas tuvieron una influencia en el uso y ejecución de los repertorios de acción colectiva que fueron utilizados por los manifestantes. Cuenta, además, con un aparato metodológico que estuvo conformado por tres herramientas: la entrevista semi-estructurada, la observación participante y el registro hemerográfico y de redes sociales (virtuales). El artículo hace un ejercicio epistémico en el que se recupera la voz de las y los participantes en dichas movilizaciones y muestra extractos de entrevista, así como notas periodísticas que triangulan las narrativas.

Las condiciones de la desigualdad, pandemia y resistencias en las comunidades indígenas de Oaxaca, México
Authors: Bautista Martínez Eduardo Carlos , Juárez López Ivan Israel
Published: July 2021

Este artículo tiene como objetivo analizar las condiciones de la desigualdad social y su relación con la pandemia COVID-19 en comunidades indígenas de Oaxaca, una entidad federativa del sureste de México que registra una amplia diversidad cultural y lingüística expresada en 16 grupos étnicos. La temática resulta relevante ante las respuestas de las comunidades para revertir los efectos de la pandemia en donde se revelan antiguas y nuevas desigualdades históricas. No obstante, lejos del papel de víctimas, se están desplegando resistencias locales que reconfiguran subjetividades de rechazo al pensamiento universal y homogéneo de la pretendida modernidad que las coloca como “atrasadas” y “pre-modernas” que requieren civilizarse para mejorar sus condiciones sociales. Para alcanzar el objetivo trazado, en primer lugar, se analiza la manera en que la desigualdad se ha gestado en las comunidades indígenas. Se concluye que la desigualdad no es un defecto de la vida local sino una característica de un largo proceso histórico. En segundo lugar, se analiza la incidencia de la pandemia COVID-19. Por último, se retoma la centralidad de las resistencias locales en donde se entremezclan antiguos reclamos y nuevas demandas colectivas.
Programas Integrales Urbano-Sociales PIUS y Casa Analco FABUAP. Dos proyectos en la periferia y el centro de la ciudad en búsqueda de la participación ciudadana
Authors: Hernández Sánchez Adriana
Published: July 2021

This work exemplifies a search for participation for the promotion of urban-architectural projects both in the center and in the periphery of a Mexican city such as Puebla, where twenty years ago few activities were developed in which the main actors were the inhabitants. Fortunately, in recent years it has been possible to carry out specific actions where participation is a key part of having a less technical vision on the part of architects, urban planners and heritage conservators.The first project is the Integral Urban Social Program in which, through a municipal action, an attempt was made to implement a participatory process in sectors considered to be of extreme poverty where municipal government programs tried to impact the areas called PIUS. An important part was the Participatory Design process that mobilized the main universities of the city through young architecture students to carry out a series of projects where the condition was to have contact with the communities.In the case of the Casa Analco project, a university initiative in the historic centre of the city in a very traditional neighbourhood (16th century) with problems of deterioration, abandonment and insecurity, with which the university-neighbourhood link is currently promoted and in where space has been the pretext to promote university participation in the rehabilitation of a building, but at the same time in a rapprochement with the neighbourhood.Through these two cases it is confirmed that it is possible to make participation possible through a process that must be adapted to each place, these experiences leave a series of reflections in different areas, from which a basic process can be broken down to encourage it through organization, promotion, awareness of the work team, knowledge of the place, time, evaluation, management and adaptability.

Published: July 2021

Selective retinal therapy (SRT) employs a micro-second short-pulse lasers to induce localized destruction of the targeted retinal structures with a pulse duration and power aimed at minimal damage to other healthy retinal cells. SRT has demonstrated a great promise in the treatment of retinal diseases, but pulse energy thresholds for effective SRT procedures should be determined precisely and in real time, as the thresholds could vary with disease status and patients. In this study, we present the use of a multi-port fiber-based interferometer (MFI) for highly sensitive real-time SRT monitoring. We exploit distinct phase differences among the fiber ports in the MFI to quantitatively measure localized fluctuations of complex-valued information during the SRT procedure. We evaluate several metrics that can be computed from the full complex-valued information and demonstrate that the complex contour integration is highly sensitive and most correlative to pulse energies, acoustic outputs, and cell deaths. The validity of our method was demonstrated on excised porcine retinas, with a sensitivity and specificity of 0.92 and 0.88, respectively, as compared with the results from a cell viability assay.
Concept and implementation study of advanced DSP-based fiber-longitudinal optical power profile monitoring toward optical network tomography [Invited]
Authors: Tanimura Takahito , Yoshida Setsuo , Tajima Kazuyuki , Oda Shoichiro , Hoshida Takeshi
Published: July 2021

A new class of digital signal processing (DSP)-based fiber-longitudinal optical power profile monitor has recently been proposed and demonstrated toward optical network tomography that captures the whole physical status of an optical network, including in-span and wavelength-specific power profiles over a multi-span transmission light path. In this invited paper, we review the monitor that disentangles signal waveforms received by a standard digital coherent receiver to a distance-wise power profile over a multi-span transmission link and discuss its implementation aspect, including the advantages and limitations of its cloud/edge implementation, the dependency of the number representation in its algorithm, and a feasibility study on field-programmable gate array implementation.
Reconfiguring multicast sessions in elastic optical networks adaptively with graph-aware deep reinforcement learning
Authors: Tian Xiaojian , Li Baojia , Gu Rentao , Zhu Zuqing
Published: July 2021

With the fast deployment of datacenters (DCs), bandwidth-intensive multicast services are becoming more and more popular in metro and wide-area networks, to support dynamic applications such as DC synchronization and backup. Hence, this work studies the problem of how to formulate and reconfigure multicast sessions in an elastic optical network (EON) dynamically. We propose a deep reinforcement learning (DRL) model based on graph neural networks to solve the sub-problem of multicast session selection in a more universal and adaptive manner. The DRL model abstracts topology information of the EON and the current provisioning scheme of a multicast session as graph-structured data, and analyzes the data to intelligently determine whether the session should be selected for reconfiguration. We evaluate our proposal with extensive simulations that consider different EON topologies, and the results confirm its effectiveness and universality. Specifically, the results show that it can balance the trade-off between the number of reconfiguration operations and blocking performance much better than existing algorithms, and the DRL model trained in one EON topology can easily adapt to solve the problem of dynamic multicast session reconfiguration in other topologies, without being redesigned or retrained.
Intensity distribution in random lasers: comparison between a stochastic differential model of interacting modes and random phase sum-based models

Published: July 2021

Random lasers (RLs) are a special type of laser with a feedback mechanism arising from the random photon scattering in a disordered medium. Their emitted intensity is inherently stochastic. Here we compare results for the intensity distribution from two classes of models. The first concerns electromagnetic wave scattering in a random medium with field amplitudes and phases as independent random or locally correlated variables [random phase sum (RPS)-based models]. In the second, stochastic differential equations describe the mode dynamics in a random medium. Whereas RPS-based models imply Rayleigh, exponential, and

We present a C-band 6-mode 7-core fiber amplifier in an all-fiberized cladding-pumped configuration for space division multiplexed transmission supporting a record 42 spatial channels. With optimized fiber components (e.g. passively cooled pump laser diode, pump coupler, pump stripper), high power multimode pump light is coupled to the active fiber without any noticeable thermal degradation and an average gain of 18 dB and noise figure of 5.4 dB are obtained with an average differential modal gain of 3.4 dB.
Experimental demonstration of spatial rogue waves in the passively Q-switched Nd:YAG laser
Authors: Navitskaya Roza , Stashkevich Ihar , Derevyanko Stanislav , Karabchevsky Alina
Published: July 2021

The generation of spatial rogue waves, or “hot spots,” is demonstrated experimentally in the passively

Q

-switched Nd:YAG laser system operating in a low-power regime well below the self-focusing limit. Here, we report the dependence of rogue wave statistics on the number of transverse modes that interact in the laser cavity. Our observations show that spatial rogue waves are most likely to occur when the laser exhibits complex output beam configurations that are formed by a large number of interacting high-order transverse modes. These results confirm the hypothesis that one of the main factors affecting the emergence of spatial rogue waves in solid-state lasers is the number of laser transverse modes.
Millisecond-long suppression of spectroscopic optical signals using laser filamentation
Authors: Skrodzki Patrick J. , Burger Miloš , Finney Lauren A. , Nawara Robert , Nees John , Jovanovic Igor
Published: July 2021

Ultrashort laser pulse filamentation in air can extend the delivery of focused laser energy to distances greatly exceeding the Rayleigh length. In this way, remote measurements can be conducted using many standard methods of analytical spectroscopy. The performance of spectroscopic techniques can be enhanced by temporal gating, which rejects the unwanted noise and background. In the present work, we investigate the thermal relaxation of air in the wake of single-filament plasmas using shadowgraphy. We demonstrate that the transient change in refractive index associated with relaxation of the gas can be used to reject both continuous and time-varying spectroscopic signals, including emission from laser-produced plasmas. This method can augment temporal gating of simple optical detectors.
Embedded nanometer position tracking based on enhanced phasor analysis
Authors: Ma Hongqiang , Liu Yang
Published: July 2021

We present an embedded real-time 1D position tracking device at a
nanometer precision. The embedded algorithm extracts the most
appropriate region of the signal without manual intervention and
estimates the position based on the phase shift from the signal’s
first Fourier harmonic. Using simulated datasets, we demonstrate that
the proposed approach can achieve a similar precision to the
state-of-the-art maximum likelihood fitting-based method while
executing over four orders of magnitude faster. We further implemented
this algorithm on a low-power microprocessor and developed a simple,
compact, and low-cost embedded position tracking device. We
demonstrate nanometer tracking precision in real-time
drift tracking experiments.
Über Ähnlichkeiten heutiger Coachingverständnisse zum Supervisionsdiskurs zwischen 1945 und 1975. Ein ideengeschichtlicher Essay
Authors: Walpuski Volker Jörn
Published: July 2021

Der Essay skizziert die Ideengeschichte eines funktionalisierenden und optimierenden Coachingverständnisses und erschließt dafür Quellen, um damit einen Anstoß für weitere Forschungsarbeiten zu geben. Dabei ist der Beitrag nur eine erste diskursanalytische Annäherung, weil Coachingverständnisse hochgradig heterogen sind, für die frühe Geschichte der Supervision nur ein unzureichender Forschungsstand vorliegt, insbesondere in Hinblick auf ihre Ideengeschichte und die erschlossenen Quellen, und sich die Entwicklung nur in der Analyse der komplexen und vielsprachigen wissenschaftlichen und praktischen Austauschprozesse insbesondere zwischen den USA und dem westlichen Europa rekonstruieren lässt. Für die Forschung wurden zahlreiche Quellen zwischen 1950 und 1980 erschlossen. Es kann gezeigt werden, dass sich einzelne Konzeptbestandteile von Coaching bereits zwischen 1945 und 1975 im Diskurs um Praxisberatung und Supervision im Kontext der Sozialen Arbeit (Social Casework, Groupwork) nachweisen lassen. Offen bleibt, ob sich Coaching unabhängig davon oder darauf aufbauend entwickelt hat. Eine systematisierte Forschung zu diesen Zusammenhängen steht aus.
The transcription factor LAG-1/CSL plays a Notch-independent role in controlling terminal differentiation, fate maintenance, and plasticity of serotonergic chemosensory neurons
Authors: Maicas Miren , Jimeno-Martín Ángela , Millán-Trejo Andrea , Alkema Mark J. , Flames Nuria
Published: July 2021

During development, signal-regulated transcription factors (TFs) act as basal repressors and upon signalling through morphogens or cell-to-cell signalling shift to activators, mediating precise and transient responses. Conversely, at the final steps of neuron specification, terminal selector TFs directly initiate and maintain neuron-type specific gene expression through enduring functions as activators. C. elegans contains 3 types of serotonin synthesising neurons that share the expression of the serotonin biosynthesis pathway genes but not of other effector genes. Here, we find an unconventional role for LAG-1, the signal-regulated TF mediator of the Notch pathway, as terminal selector for the ADF serotonergic chemosensory neuron, but not for other serotonergic neuron types. Regulatory regions of ADF effector genes contain functional LAG-1 binding sites that mediate activation but not basal repression. lag-1 mutants show broad defects in ADF effector genes activation, and LAG-1 is required to maintain ADF cell fate and functions throughout life. Unexpectedly, contrary to reported basal repression state for LAG-1 prior to Notch receptor activation, gene expression activation in the ADF neuron by LAG-1 does not require Notch signalling, demonstrating a default activator state for LAG-1 independent of Notch. We hypothesise that the enduring activity of terminal selectors on target genes required uncoupling LAG-1 activating role from receiving the transient Notch signalling.

Os casos de inundação costumam ser mais frequentes no verão na região Sudeste do Brasil, podendo ser influenciados por sistemas ou fenômenos atmosféricos que agravam os eventos. O objetivo deste estudo foi verificar a ocorrência de inundações com as chuvas de verão, sob a influência dos períodos com e sem El Niño, no município de São Gonçalo, localizado na região metropolitana do Estado do Rio de Janeiro. Para isso foram analisados os dados de chuva da Estação Climatológica da Universidade do Estado do Rio de Janeiro entre 2005 e 2018. As análises consistiram em verificar a quantidade de eventos de chuva correspondentes às intensidades leve, moderada e forte, bem como o acumulado de chuva nos verões de cada ano, dentre os quais houve intervalos em que ocorreu o fenômeno El Niño. Os resultados contemplaram uma relação entre os registros da quantidade de inundações com os eventos de chuvas fortes (11,6%), observando que há uma suscetibilidade a inundações, pois foram registradas 82,8% de ocorrências no município somente nos anos com El Niño e 16,9% casos em anos sem El Niño.
Responses of populations for coping with an extreme event: Saint-Martin and Saint-Barthélemy in the wake of hurricane Irma
Authors: Defossez Stéphanie , Gherardi Monique
Published: July 2021

The intense hurricane season of 2017 in the North Atlantic brought a number of major hurricanes including Hurricane Irma (cat. 5), which landed on the French islands of St. Martin and St. Barthélemy. These two French Overseas Collectivities, separated by a distance of some 20 kilometres, have very different territorial and social characteristics. The study reported in this article is part of a scientific feedback conducted a few weeks after Irma. The social approach to the disaster conducted within this research framework aims to characterise the behaviour and implications of the inhabitants in the experience of the event, placed in a social and territorial context thanks to narrative interviews administered in situ. The comparative approach reveals similar behaviour before and during the hurricane, but individual and collective social and territorial factors guided very distinct post-event reactions.
Volcanic hazards assessment of Oldoinyo Lengai in a data scarcity context (Tanzania)
Authors: Rey Tony , Leone Frederic , Defossez Stéphanie , Gherardi Monique , Parat Fleurice
Published: July 2021

The objective of our study is to establish an assessment of four volcanic hazards in a country threatened by the eruption of the OlDoinyo Lengai volcano. The last major eruption dates back to 2007-2008 but stronger activity in 2019 has revived the memory of volcanic threats to the Maasai and Bantu communities and human activities (agro-pastoral and tourism). The methods chosen have had to be adapted to the scarce and incomplete data. The volcanic hazards and their probability of occurrence were analysed on the basis of data available in the scientific literature and were supplemented by two field missions combining geography and hydro-geomorphology. Our study enabled us to map the hazards of ash fall, lava flows, lahars and avalanches of debris. Each hazard was spatialised by being ascribed an intensity. They are sometimes synchronous with the eruption sometimes they occur several months or years after a volcanic eruption. The results are the first step towards developing a volcanic risk management strategy, especially for the pastoral communities living around Lengai and for the growing tourist activities in this area.

Critical Turning Points During Lesson Study: Student Misconceptions Spark Teacher Learning
Authors: Barber Krystal
Published: July 2021

During lesson study teachers collaborate to design, teach, observe, and reflect on a lesson with the overarching goals of improving instruction and increasing student learning. This article examines how a 6th grade mathematics lesson study project challenged teachers’ ideas and assumptions about their students’ understanding of fraction concepts. Significant misconceptions were revealed during the teaching of the lesson, prompting teacher learning and changes to instruction. The results highlight critical turning points during the process where evidence collected during lesson observations revealed student struggles and changed how teachers supported their students’ thinking moving forward. This article also documents one teacher’s journey as she recognizes the need for visual modeling and justification of math concepts to build deeper understanding. There are many different ways lesson study has been implemented in the United States, yet in many ways the effectiveness of lesson study remains uncertain. This paper focuses on key points during the lesson study process that can lead to the development of knowledge and practice.

Status in Early Modern and Modern World Politics
Authors: Youssef Ramy
Published: July 2021

In this article, Ramy Youssef compares historically varying structures and semantics of world political status competition. Early modern and modern rankings that represent the world political status of royal titles, or modern states, respectively, serve as empirical material. It is shown that status competition in the early modern period can neither semantically nor structurally be distinguished from conflicts, whereas in modern world politics competition is framed as a distinct social relationship and as an alternative to conflicts. Methodological and epistemological conclusions are drawn from the findings, suggesting that more caution should be taken when applying modern terms to historical contexts.
Network Power Europe and Competition at the UN Human Rights Council
Authors: Boyashov Anatoly
Published: July 2021

The chapter's argument anchors the debates on what type of a competitor the European Union is. On a larger scale, it addresses the question about the nature of competition within the United Nations. A large share of European integration literature suggests that the EU competes as a “normative power Europe” thus identifying competition as a struggle for prestige and status. The proponents of the other perspective pinpoint the EU identity as a “market power Europe”-to gain advantages, the EU hence seeks to guide competition with its wealth. This chapter argues the augmenting complexity of international organizations pushes the EU to act as “network power Europe” and compete for the structural position a “bridge” in complex networks.
Competing Powers
Authors: Russ Daniela , Turnbull Thomas
Published: July 2021

The interwar years saw the rise of debates and comparisons around the growth and efficiency of national power economies. The article interprets this 'energetic productivism' in terms of indirect geopolitical competition. While this form of competition clearly did not rule out national conflicts over resources and territories, it created a new medium--the national power economy--via which supremacy could be asserted. The article outlines the roots of energetic productivism in the 19th century and shows how it related to imperial competition around the turn of the century. It presents two forms of energetic productivism that emerged out of two distinct nation states, Great Britain and the Soviet Union. On the basis of these examples, the article argues that 'power competition' was wedded to two wider political conflicts. The first was between Great Britain and 'rising' rival powers whose ascendence was beginning to end its industrial and political hegemony. The second power competition occurred between the Soviet Union and the capitalist countries whom this experimental new polity sought to supersede. The article concludes by contrasting these two iterations of energetic productivism with a more well-known formulation of energetic statehood proposed in the US in the 1930s.
Small, Smart, Powerful?
Authors: Myatt Madeleine
Published: July 2021

“Size matters in international relations,” (Steinsson /Thorhallsson 2017: 1), but does size still matter in the digital age, and in the cyber domain? Scholars have long believed that larger states are better equipped for state competition due the size of their populations, economies, and militaries based on a respective size/power calculus. This chapter explores how digital technological innovation help small states like the Nordic countries to gain influence on the world political stage and in the cyber domain. Emphasis is put on the way how smaller states like Estonia or Finland make use of this new asymmetric toolbox of 'cyber power' to gain leverage in the international security realm.
Competition During Covid-19
Authors: Tworek Heidi
Published: July 2021

This afterword considers the role of competition during Covid-19. It incorporates insights from the chapters in this edited volume to understand how the global phenomenon of a pandemic has come to be portrayed through national rankings of cases and deaths. Statistics have desensitized, making the pandemic more about a competition over cases than about mourning those who have passed away and finding public health solutions to prevent further cases. I argue that we can best understand how Covid-19 statistics have spurred national competition and, at times, obscured much more important effects by turning to history, epidemiology, sociology, and international relations.
El aislamiento penitenciario:De la espiatio religiosa a su secularización inocuizadora
Authors: Stroppa Rachele
Published: July 2021

¿De dónde surge la idea de aislar a las personas privadas de libertad? Incluso ¿Por qué se decidió aislar para privar de libertad? ¿Por qué hoy en día se sigue aplicando el aislamiento penitenciario? Estas son algunas de las preguntas a las que se tratará de responder con este artículo. A través de una aproximación a una genealogía del aislamiento penitenciario, se estudiarán las funciones del aislamiento en las primeras etapas de la historia del encierro y durante la fase de recepción de los sistemas penitenciarios en Europa —y en particular en el Estado español— en aras de comprender mejor su configuración y sus finalidades actuales en el sistema penitenciario español (y catalán). Si en un principio con el aislamiento se pretendía lograr la reforma moral del preso, a través de la espiatiopenitencial, paulatinamente el solitaryconfinementse asentó como la principal técnica disciplinar para conseguir el sometimiento del preso al poder y a la autoridad, además de configurarse como la práctica preminente para inocuizar y neutralizar a los «peligrosos»

Performance Enhancement of Recycled Aggregate Concrete – An Experimental Study
Authors: Jagan Sivamani , Neelakantan Thurvas Renganathan , Saravanakumar Palaniraj
Published: July 2021

Extensive studies have been performed on the mechanical and durability properties of the concrete prepared with recycled coarse aggregates (RCA), however, only modest consideration has been given to the studies on the behaviour of RAC prepared by alternative mixing approach techniques. This study presents the mechanical properties of the recycled aggregate concrete (RAC) with different percentages of RCA prepared by normal mixing approach (NMA), two-stage mixing approach (TSMA) and sand enveloped mixing approach (SEMA) techniques. The manufactured concrete mixtures were tested for compression, tension, flexure and elastic modulus at 7, 28 and 90 days. The results indicate that the mechanical properties of the RAC (with 100% of RCA) prepared through TSMA and SEMA were improved by 9.36 and 12.14% at 28 days. Perhaps, prolonged curing to TSMA and SEMA mixtures improved the mechanical properties of the RAC that is nearly equal to normal aggregate concrete (NAC) prepared by NMA.

O artigo problematiza a chamada â€œdivisÃ£o digitalâ€, relacionada Ã  desigualdade na posse, no uso e nos benefÃ­cios extraÃ­dos dos recursos tecnolÃ³gicos devido Ã  estratificaÃ§Ã£o social que impÃµe clivagens econÃ´micas, polÃ­ticas, sociais e culturais. A partir dos estudos de sociologia da tÃ©cnica e dos conceitos de socializaÃ§Ã£o, capital tecnolÃ³gico e habitus informacional, o objetivo Ã© analisar a posse e o uso das Tecnologias da InformaÃ§Ã£o e ComunicaÃ§Ã£o (TICs), sob a perspectiva da geraÃ§Ã£o e da ocupaÃ§Ã£o. A realizaÃ§Ã£o de um estudo de corte transversal, com a aplicaÃ§Ã£o de questionÃ¡rios a uma amostra de 324 estudantes, professores e servidores tÃ©cnico-administrativos (ativos e aposentados) da Universidade Federal de ViÃ§osa (UFV), revelou que a geraÃ§Ã£o e o status ocupacional tÃªm efeito na posse, nas formas/frequÃªncias de uso e na autopercepÃ§Ã£o das capacidades tecnolÃ³gicas, estando aliados tambÃ©m a fatores como gÃªnero, escolaridade e renda. Os resultados apontaram que grande parte dos estudantes, professores ativos e aposentados e servidores tÃ©cnico-administrativos ativos realiza mÃºltiplas atividades online, declaram elevado tempo de uso das TICs e uma percepÃ§Ã£o mais favorÃ¡vel sobre as competÃªncias digitais. Enquanto, os servidores tÃ©cnico-administrativos aposentados registraram os menores percentuais de realizaÃ§Ã£o de prÃ¡ticas online, frequÃªncias de uso mais baixas e uma percepÃ§Ã£o menos favorÃ¡vel sobre suas competÃªncias. Outras diferenÃ§as estatisticamente significativas tambÃ©m foram observadas.
O software IRAMUTEQ como ferramenta metodolÃ³gica para anÃ¡lise qualitativa nas pesquisas em educaÃ§Ã£o profissional e tecnolÃ³gica
Authors: Silva Silvani , Ribeiro Eduardo Augusto Werneck
Published: July 2021

Trata-se de uma pesquisa de natureza qualitativa, que busca investigar quais sÃ£o as referÃªncias bibliogrÃ¡ficas que discutem o tema: escola e democracia na EducaÃ§Ã£o Profissional TecnolÃ³gica (EPT). Este trabalho apresenta a experiÃªncia de uso do software Iramuteq para analisar as referÃªncias bibliogrÃ¡ficas no contexto de uma pesquisa em curso no mestrado em EducaÃ§Ã£o Profissional e TecnolÃ³gica (ProfEPT), do Instituto Federal Catarinense polo Blumenau â€“ SC. Foram consultadas as plataformas de dados Web of Science e Scopus e selecionados 157 artigos relacionados com o tema. Os resumos dos artigos foram processados e analisados com o uso do software Iramuteq. A pesquisa mostrou que o software Iramuteq Ã© uma importante ferramenta de apoio para a anÃ¡lise de textos em pesquisas qualitativas e estÃ¡ disponÃ­vel gratuitamente. Os resultados mostraram promissores com significÃ¢ncia estatÃ­stica, mesmo diante de um grande volume de referÃªncias. A temÃ¡tica estÃ¡ em expansÃ£o (nÂº de artigos/ano), todavia, com a ajuda do software verificou-se que esta produÃ§Ã£o cientÃ­fica nÃ£o versam a EPT. O estudo contribuiu para conhecimento de novos instrumentos metodolÃ³gicos, alÃ©m de apontar novas perspectivas para aprofundar as pesquisas bibliogrÃ¡ficas e documentais relacionadas ao objeto da pesquisa que podem ser Ãºteis no desenvolvimento de trabalhos futuros.
ContribuiÃ§Ãµes do enfoque ciÃªncia tecnologia e sociedade em um projeto de ensino: um caminho para o consumo sustentÃ¡vel

Published: July 2021

O enfoque da CiÃªncia, Tecnologia e Sociedade (CTS) no contexto da EducaÃ§Ã£o permite o trabalho com temas de natureza social, polÃ­tica, ambiental, entre outros, que envolvem a participaÃ§Ã£o ativa no indivÃ­duo frente aos problemas da sociedade no sentido de refletir, criticar e agir. Assim, o objetivo do trabalho foi desenvolver aprendizagens conceituais e atitudinais a partir da temÃ¡tica lixo urbano, em um projeto de intervenÃ§Ã£o, com atividades envolvendo sustentabilidade, reutilizaÃ§Ã£o, consumismo e responsabilidades. A pesquisa teve natureza qualitativa, pautada em princÃ­pios da pesquisa-aÃ§Ã£o, desenvolvida pela pedagogia de projetos, participando treze (13) alunos do 1Âº ano do Ensino MÃ©dio, de uma escola pÃºblica localizada no municÃ­pio de Manaus-AM, todos voluntÃ¡rios. A coleta de dados ocorreu por meio de questionÃ¡rios, produÃ§Ã£o textual, discussÃµes e exposiÃ§Ã£o oral e os dados foram analisados qualitativamente de forma exploratÃ³ria. Os resultados revelaram que os alunos apresentaram indÃ­cios de compreensÃ£o conceitual dos termos relativos a temÃ¡tica como: lixo, resÃ­duo sÃ³lido, reciclagem, reutilizaÃ§Ã£o e buscaram traÃ§ar associaÃ§Ãµes com conceitos quÃ­micos e propor soluÃ§Ãµes para as questÃµes ambientais, se utilizando da sustentabilidade e das responsabilidades sociais. Mostraram-se, sensibilizados e dispostos a mudar suas atitudes frente ao problema.
Uso dos quadros de competÃªncia digital DigComp e DigCompEdu em educaÃ§Ã£o: revisÃ£o de literatura
Authors: Santos Cassio Cabral , Mattar JoÃ£o , Pedro Neuza Sofia Guerreiro
Published: July 2021

O objetivo desta revisÃ£o foi investigar a literatura educacional fundamentada nos quadros de competÃªncia digital DigComp e DigCompEdu, por meio de uma revisÃ£o de escopo ou mapeamento (ParÃ© et al., 2015), seguindo as orientaÃ§Ãµes metodolÃ³gicas de Okoli (2019). As buscas resultaram em 327 trabalhos, dos quais foram selecionados 18 artigos analisados considerando o contexto e objetivos da pesquisa, a abordagem metodolÃ³gica adotada, os instrumentos utilizados, o pÃºblico envolvido e as conclusÃµes. Os resultados encontrados permitiram verificar que as pesquisas analisadas tÃªm utilizado primordialmente abordagem quantitativa, baseadas em questionÃ¡rios apoiados por diversas metodologias, focadas principalmente na avaliaÃ§Ã£o da competÃªncia digital de professores no ensino superior, com menor incidÃªncia na educaÃ§Ã£o bÃ¡sica, e junto de alunos. Esses quadros sÃ£o tambÃ©m utilizados para desenvolver propostas de atividades formativas e analisar dados. Identifica-se a necessidade de formaÃ§Ã£o para o desenvolvimento de competÃªncias digitais tanto de professores como de alunos.

Published: July 2021

Let X be a smooth projective complex curve of genus g ≥ 2 and let M
X
(2,Λ) be the moduli space of semi-stable rank-2 vector bundles over X with fixed determinant Λ. We show that the wobbly locus, i.e. the locus of semi-stable vector bundles admitting a non-zero nilpotent Higgs field, is a union of divisors 𝓦
k
⊂ M
X
(2,Λ). We show that on one wobbly divisor the set of maximal subbundles is degenerate. We also compute the class of the divisors 𝓦
k
in the Picard group of M
X
(2, Λ).
Pythagorean harmonic summability of Fourier series
Authors: Haidar Nassar H. S.
Published: July 2021

This paper explores the possibility for summing Fourier series nonlinearly via the Pythagorean harmonic mean. It reports on new results for this summability with the introduction of new concepts like the smoothing operator and semi-harmonic summation. The smoothing operator is demonstrated to be Kalman filtering for linear summability, logistic processing for Pythagorean harmonic summability and linearized logistic processing for semi-harmonic summability. An emerging direct inapplicability of harmonic summability to seismic-like signals is shown to be resolvable by means of a regularizational asymptotic approach.
Instrumentalizing the book: Anne Carson’sNoxand books as archives
Authors: Davis Brian
Published: July 2021

This article introduces an experimental mode of contemporary writing and bookmaking that I callmultimodal book-archives, an emergent mode of contemporary literature that constructs narratives and textual sequences through the collection and representation of reproduced texts and other artifacts. In multimodal book-archives the book-object is presented as a container designed to preserve and transmit textual artifacts. In this article, I examine Anne Carson’sNox(2010) as a case study in archival poetics, exemplifying the “archival turn” in contemporary literature. My analysis draws attention to how writing, subjectivity, knowledge, history, and memory in the digital age are increasingly configured through distributed networks of people and artifacts in different social and institutional spaces, demonstrating howNoxfunctions not only as an instrument of psychological rejuvenation, but as an aesthetic instrument for documenting, ordering, listing, and juxtaposing disparate bits of information and memory into cathartic self-knowledge. Carson’s archival poetics is deeply personal, laden with private symbols and metaphors that readers are asked to collocate, cross-reference, and translate as part of the archival reading process. If grief is a kind of chaos, then Carson’s archival poetics instrumentalizes the book as a tool for ordering that chaos into something manageable, useful, even beautiful.

The Maximum Power Cycle Operating Between a Heat Source and Heat Sink with Finite Heat Capacities
Authors: Ibrahim Osama M. , Bourisli Raed I.
Published: July 2021

This study aims to identify the thermodynamic cycle that produces the maximum possible power output from a heat source and sink with finite heat capacities. Earlier efforts used sequential Carnot cycles governed by heat transfer rate equations to determine the maximum power cycle. In this paper, a hypothesis is proposed where the heat capacities of the heat addition and rejection processes of the proposed maximum power cycle are assumed to match the heat source and sink, respectively. The result is a simple thermodynamic model that approximately defines the performance and shape of the proposed maximum power cycle, which are compared and verified with the shape and performance of optimized sequential Carnot cycles with closely matching results.
