Two thermal cylinders with varied shapes (circular (R = 0.15), square (L = 0.15), ellipse (Rx = 0.2, Ry = 0.15), and circular (R = 0.15) near the cold wall of the square enclosure where the (AR = 0.7) is explored numerically in the present study. The nanofluid is contained within the cavity (Al2O3). Left-side vertical wall and inner bodies are maintained at a fixed temperature (Th), while the right-side vertical wall is maintained at a cool temperature (Tc). Thermal insulation is used to insulate the upper and lower horizontal walls. This code is used the (technique of finite elements), which is utilized to resolve dimensionless equations in the COMSOL program. The basic parameters that were utilized in this paper where: the Rayleigh number (Ra), which ranged from 103 to 106; the percentage of solid volume (ϕ=0.06); and the aspect ratio (AR =0.7). The outcome demonstrates that: When the heated internal bodies are used in different forms, the effect of fluid movement will be different, and when the two inner bodies are combined, the highest stream function of up to 33 can be obtained. The isotherm line shows the clear and important effect of internal bodies in enhancing and improving heat transfer. For the two-square case, the average Nu was at its lowest point. While the highest Nu was for two – the ellipse case followed by the cylinder – the ellipse and the two circular cylinders.

Published: September 2022

The current analytical study is concerned with studying the impact of Cattaneo-Christov heat flux of an incompressible flow which obeys Carreau nanofluid inside a symmetric channel in the existence of the porous medium. The impacts of couple stress, heat generation absorption, joule heating, couple stress viscous dissipation with Soret as well as Dufour numbers are all presumed. Long wavelength and law Reynold’s number approximations are utilized for solving the governing system of equations. Furthermore, the traditional perturbation method together with the homotopy perturbation technique (HPM) are applied to obtain the resultant solutions of these equations. The different physical parameters on velocity, temperature and nanoparticles concentration distributions are illustrated through a set of graphs. It is found that the elevate in the slip velocity parameter dwindle the velocity. Meanwhile, the rise in the value of thermal relaxation time parameter led to decay the temperature of the fluid. Over and above, enhancing the nano Biot number value caused an enrichment in the concentration of nanofluid.

Published: September 2022

Most large and controlled buildings require high power demand with long period. However, there are restrictions on building facilities and image when it comes to reducing electricity consumption. Another option is to install a roof-top solar power system, though due to the small installation area, it will only partially reduce energy use. Hybrid energy storage systems in combination with AGM batteries and LFP batteries are now offered as a lower cost energy management solution. AGM batteries are constrained in their ability to produce current, hence a larger current supply will reduce the battery's useable capacity. Therefore, in order to respond to high demand with long period, this research proposed a separate multi-level threshold control of the battery packs, and used the control factor in the form of current ratio to divide the load response for each battery type: On-Peak in AGM: LFP at 0.7:0.3, Off-Peak in AGM : LFP at 0.5 : 0.5. And when one battery was not ready for use, the other battery would be run at full capacity. The results showed that the AGM battery had a peak discharge current of 12.7A, or approximately 0.5C when coupled with an LFP battery, and when processing power storage system capacity, a loss of 8.99 kWh occurred. or 6.8% of the overall capacity.

Among the well-established cooling method via thermoelectricity is Peltier effect. Often known as thermoelectric cooling, the cooling effect is achieved without the use of any refrigerant, and this holds several advantages for industrial applications. In this paper, the process of designing and testing of low-cost thermoelectric cooling box were addressed. The design process was elaborated and the main components in the system such as the Peltier module, fan, cooling box made from among others were detailed out. The developed cooling box was then tested experimentally in terms of cooling capabilities by using canned drinks as items to be cooled. It was found that the temperature reduction was notably fast and successfully provided cooling to the canned drinks. The low cost components and materials used suggests its economics and potentials to be used on the do-it-yourself (DIY) basis as a hobby as well as commercial use.

Published: September 2022

Dam failure is undeniably catastrophic and one of its major causes is the soil erosion near the dam structure. In this paper, the characteristics and compositions of soil sediment in dam spillway structure were investigated to determine its impact on the occurrence of erosion. Four suspended samples were taken from the vicinity of Ogee dam spillway. Sediment analysis using scanning electron microscope revealed that the soils consist of relative high metal contents of aluminium, iron and magnesium. These metals will attribute to the erosion of dam wall, which subsequently reduce the durability of wall against high hydrostatic pressure exerted by the reservoir. Nonetheless, as the average sizing of suspended particles at each sampling location were capped at 4.55 μm, the damages incurred to the dam were minimal. Additionally, the suspended particles around the dam spillway was numerically simulated with the inclusion of discrete phase model. The numerical data were in great consensus with the corresponding finding attained from the particle image velocimetry experimental of a scaled-down dam model, with the discrepancy not more than 4.89 %. The movement of suspended particles due to the water flow can be tracked numerically and it is found the sediment prone to accumulate at the vicinity of dam spillway.
Thermal Conductivity-Based Optimisation of Surfactant on Hybrid Nanofluid
Authors: Muhammad Arif Harun  , Nor Azwadi Che Sidik
Published: September 2022

A surfactant is an efficient approach for increasing the stability of nanofluids. However, excessive surfactant degrades the hybrid nanofluid's outstanding thermal conductivity. Additionally, there was only a little research on optimising the amount of surfactant used in nanofluids depending on their thermal conductivity. As a result, it is critical to ensure that the created nanofluid is stable without impairing thermal conductivity. The optimisation was carried out in this study utilising Design Expert 11. Surfactant ratios and the mixing ratio of hybrid nanofluid were employed as variables, while thermal conductivity was used as the response. Additionally, the concentration and temperature of the hybrid nanofluid remained constant at 0.5 vol% and 40 °C, respectively. The results indicate that a 1:10 ratio of surfactant to TiO2 is the optimal proportion for the generated TiO2-GNP hybrid nanofluid. The correct amount of surfactant results in a hybrid nanofluid with high thermal conductivity and good stability.

Authors: Shean Ti Teen  , Keng Wai Chan
Published: September 2022

This study shows the evaluation of the indirect evaporative cooling system beneath the roof that aims to reduce the cooling load in buildings. As the energy demand for space cooling increases over the years, the evaporative cooler that has lower energy consumption can be a green technology for space cooling compared with air-conditioning systems. An example of an evaporative roof cooling method that is commonly used is a rooftop sprinkler system. This study emphasizes the evaluation of the performances of an indirect evaporative cooler and rooftop sprinkler system in terms of temperature reduction and cooling capacity. The modelling is done by using the sol-air temperature to estimate the solar heat gain. Then, the cooling power of each system is calculated, and finally, the indoor temperature for the respective system can be determined. The finding shows that the temperature drop for the indirect evaporative cooler is 9.2°C, whereas for the rooftop sprinkler system, it is only about 4.4°C. The simulated cooling load of the indirect evaporative cooler for this test house can go up to 49.2W.

Published: September 2022

Seiring dengan memburuknya kerusakan lingkungan akibat peningkatan emisi karbon, para pembuat kebijakan telah melakukan serangkaian langkah untuk menekan angka emisi ini yang salah satunya melalui konsep ‘label karbon,’ dimana tulisan ini hendak mengkaji efektivitas penerapannya pada aspek produksi makanan kemasan. Penerapan ide ini sejatinya dirancang sebagai suatu insentif bagi pengembangan rantai produksi makanan kemasan yang mampu menghasilkan emisi karbon pada tingkat rendah serta di sisi lain berupaya mendorong partisipasi masyarakat dalam mengurangi emisi karbon melalui pemilahan produk-produk yang ada pada keranjang belanjanya. Meski begitu, tidak dipungkiri bahwa terdapat tantangan untuk merancang skema pengumpulan serta sertifikasi data yang inovatif demi menekan tingginya biaya pengimplementasian konsep kebijakan ini. Dalam rangka mengkonsepsikan pelaksanaannya di Indonesia, akan dilakukan komparasi dengan Inggris yang telah berhasil menerapkan kebijakan ini, untuk kemudian dihubungkan dengan landasan filosofis hak warga negara dalam hal mendapatkan lingkungan hidup baik dan sehat sebagaimana terdapat pada Pasal 28H UUD 1945.

Published: September 2022

In recent years, research work on the use of coal bottom ash (CBA) as a partial alternative for aggregate in concrete is on the rise. This research is aimed at examining the characteristics of lightweight foamed concrete with CBA as fine aggregate to produce environmentally sustainable product. With the volume replacement technique, CBA was used as 25%, 50%, 75%, and 100% replacement for conventional mining sand with different sieve sizes of smaller than 4.75, 2.36, and 0.6 mm in concrete. Water absorption, porosity as well as mechanical characteristics tests, including compressive strength, splitting tensile strength, and modulus of elasticity (MOE) were conducted and analyzed. X-ray diffraction and scanning electron microscopy microstructural investigations were also performed to correlate test results. The quality of concrete was investigated using a non-destructive ultrasonic pulse velocity test. According to the findings, the highest replacement level of CBA with a sieve size smaller than 0.6 mm had an impact in reducing workability. The effect of CBA particles on water absorption, MOE, compressive strength, and tensile strength depends on the size of the fine aggregate, the replacement ratio and the density. In general, substituting mining sand with CBA aggregate improved the mechanical performance of concrete, notably for the aggregate size of less than 0.6 mm. Moreover, the SEM images indicate that the addition of CBA particles decreased the size and quantity of voids in the foamed concrete.

Published: September 2022

Chemical and isotopic composition provide insights into the formation and evolution history of planets and brown dwarfs. Recent measurements of 12CO/13CO abundance ratios in the atmosphere of the young super-Jupiter YSES-1b and the isolated brown dwarf 2MASS J03552337+1133437 may point to distinct formation pathways. Here we present our analysis of 0.5 hr of science verification observations using the recently upgraded CRIRES spectrograph at ESO’s Very Large Telescope on the same brown dwarf, with the aim to detect C18O and determine the 16O/18O isotope ratio. Our free retrieval analyses confirm the previous measurement of the carbon isotope ratio, and the inclusion of the C18O molecule in our models enables an initial tentative constraint of 16O/18O =

The China Friendship traveller in the 1970s and the dilemma of propaganda: memory, emotional response and narrative
Authors: Hedén Anne
Published: September 2022

During the 1960s and 1970s, radicals from the west travelling to socialist countries in the 'Third World' tried to create an alternative pool of expertise, often with a utopian agenda. This leftwing tourism later became the subject of academic discussion and analysis. One prominent
standpoint is that the travellers involved agreed with the propaganda to which they were subjected, or at least believed in it. Others regard the travellers' loyalty to the socialist country in question as a way of improving the prospects for hegemony within left organisations at home. Another
view is that the travellers contained their criticism amongst themselves, while struggling with their experiences in the country in question. The aim of this text is to examine, through a case study, how travellers not tied up in any partybuilding struggles back home perceived and explained
their experience in China, and how this experience was understood and interpreted – and reinterpreted – in hindsight. The study is focused on the Swedish social worker Elsa Larsson, who went to China in 1977. Her impressions and reflections were documented in a short film made
with a small hand camera, in letters and notes, and in two speaker texts to her film, one from 1977 and one from 2005. The study shows that Larsson did harbour some scepticism about what was presented during her visit – but also that the expectations of friends and colleagues in Sweden
were important in how she came to tell the story of her trip. This points to a more general picture, whereby the preconceptions of the traveller's own communities were of great significance in creating the western image of Red China, in addition to the Chinese state's own propaganda. The study
contributes a tentative explanation as to why China as an alternative welfare society was so favourably received in Sweden (and in Europe) in the 1970s. When Larsson reinterpreted her material many years later she added in analysis of the problematic issue of how the travellers had in general
failed to grasp the extent of Chinese Communist Party (CCP) propaganda. It seems that, in this later phase, it was important for Larsson to continue to create a frame for her experiences, rather than to uncritically adapt to any contemporary interpretation.
Building a new old left: The first period of the Greek Marxist-Leninist movement (1963-1967)
Authors: Mais Christos
Published: September 2022

This paper analyses the first period of the Greek Marxist-Leninist movement, from its birth in 1963 until the military coup of 1967, which brought this period to an abrupt end. The movement is often referred to as 'Maoist', but, as will be detailed in brief, this is a misnomer in the
Greek case. Before discussing the all-important 19631967 period, I will provide a brief pre-history of the movement, tracing its roots back to the 1950s. The central discussion within the article is the various activities of the Greek Marxist-Leninist movement in the 1963-67 period –
namely, its publishing, trade union activity and student activism.
Vieillesse et vieillissement dans l’œuvre de Günter Grass : autour de Vonne Endlichkait
Authors: Cailleux Dorothée
Published: September 2022

Cet article se propose d’étudier l’image de la vieillesse et du vieillissement dans l’ultime recueil de poèmes de Günter Grass. Une première partie s’attache à identifier différentes représentations de la vieillesse dans l’œuvre de l’auteur antérieure au tournant autobiographique de 2006, afin de permettre une comparaison entre les motifs utilisés par Grass pour évoquer la vieillesse de personnages de fiction et ceux convoqués pour parler de sa propre vieillesse. L’analyse détaillée du recueil, en particulier de sa composition, qui occupe la deuxième et principale partie de l’article, se nourrit donc de l’étude de l’œuvre littéraire et graphique antérieure et vise à montrer que l’ouvrage, reprenant et approfondissant des thématiques présentes de longue date chez l’auteur, invite le lecteur à une expérience émotionnelle, à travers les hauts et les bas d’un âge marqué par l’affaiblissement physique et la douleur, mais aussi synonyme de liberté créative et de jouissance épicurienne de l’instant. Loin des clichés, brisant quelques tabous, les poèmes et dessins ne cachent rien de la dureté de cette phase de la vie mais renferment encore une bonne dose d’humour et d’autodérision, qui restent les armes privilégiées de Grass contre la mélancolie.
La zététique ou les usages multiples d’une mise en récit scientiste du monde social
Authors: Bodin Cyrille
Published: September 2022

Le mouvement zététique a investi, en quelques décennies, les espaces médiatiques dès lors qu’il est question de « penser » les controverses sanitaires ou environnementales. Militants, médiateurs, journalistes et « experts » en tous genres mobilisent ses éléments de langage afin de faire valoir une autorité, présentée comme « scientifique », dans un agenda médiatique. Toutefois, la zététique présente toutes les caractéristiques du scientisme, en se réalisant au travers d’une naturalisation de l’énonciation scientifique. La posture zététicienne exempte le mouvement de toute réflexivité et lui donne la possibilité de parler « au nom de la Science » sans avoir à suivre les normes méthodologiques, déontologiques ou communicationnelles régissant, pourtant, la production des connaissances par les sciences contemporaines. Reposant sur une ignorance, parfois stratégique, la zététique apparait sous la forme d’une matrice narrative permettant la construction d’une fiction sociale. Quoique se prétendant « neutre », « rationnelle » et « descriptive » du monde dans son ensemble, notamment dans ses dimensions sociales et culturelles, elle se présente plutôt sous la forme d’un récit performatif, en construisant une « réalité » conforme aux vues et aux intérêts de ses énonciateurs.

Associated outcomes of various iterations of the dedicated orthopaedic trauma room: a literature review
Authors: Biddle Kathryn , Pagidas Kelly
Published: September 2022

Scheduling urgent, orthopaedic trauma cases has long been a challenge for health care institutions. Traditionally, these cases are scheduled for an operating room (OR) slot in the middle of the night, by “bumping” elective cases to later in the day, by adding a case on after-hours, or by delaying the case for several days until an OR becomes available. As a solution to the challenges facing traditional scheduling modules, trauma centers around the country have instituted the use of a dedicated orthopaedic trauma room (DOTR). While there are multiple studies analyzing the effects of DOTRs on various outcomes, there is not a centralized review of these studies. This paper will serve as a review of the various models of the DOTR as well as the effect of the DOTR on after-hours procedures, time to surgery (TTS), duration of surgery (DOS), length of stay (LOS), cost, and surgical complications. An extensive review of the literature was performed through PubMed and Embase. 17 studies were found to meet eligibility criteria. This review suggests that DOTRs have favorable effects on after-hours procedures, cost, and surgical complications. There is variability in the data regarding the effect on TTS, DOS, and LOS.

Authors: Roca-Escoda Mireia , Legarreta-Iza Matxalen , Hernández-Cordero Ana-Lucía
Published: September 2022

El artículo analiza las experiencias y percepciones de trabajadoras de cuidado de servicios de larga duración (residencias, Servicios de Ayuda a Domicilio y Asistencia Personal) durante la pandemia provocada por la COVID-19. Concretamente, estudia cómo se han modificado, e incluso ampliado y resignificado, las dimensiones material y relacional del cuidado. Para ello, se basa en una investigación cualitativa desarrollada a través de entrevistas semidirigidas llevadas a cabo a trabajadoras de Andalucía, Aragón, Cataluña, Castilla-La Mancha, Madrid, Murcia y País Vasco. Los resultados muestran que la limpieza, la corporalidad y la dimensión relacional han cobrado especial relevancia y la protección-seguridad aparece como una nueva dimensión que amplifica el concepto de cuidado. Con ello, aportamos un mayor entendimiento y visibilidad de las actividades de cuidado y las relaciones que lo atraviesan, lo que implica un reconocimiento de la importancia de los mismos en la sostenibilidad de la vida.

Etnografía y cine en la investigación antropológica. Reflexiones desde el proyecto Transgang
Authors: Mecca Margot , Feixa Carles
Published: September 2022

Este texto presenta algunas reflexiones alrededor de la incorporación de prácticas cinematográficas en la investigación antropológica desarrolladas desde el proyecto TRANSGANG, cuyo objetivo es estudiar las bandas juveniles como agentes de mediación en doce ciudades en el sur de Europa, Norte etc. el norte de África y América. El proyecto incluye talleres de antropología visual en los que participarán jóvenes de algunas de estas ciudades, así como la elaboración de tres películas documentales sobre las bandas vistas desde dentro, a cargo de tres realizadores seleccionados tras un concurso público internacional. Aunque el cine y la antropología compartan una larga historia de fascinaciones e intercambios recíprocos, ha habido frecuentes tensiones en la relación entre ambos. En el texto exponemos cómo, desde nuestra investigación, intentamos construir una colaboración paritaria entre las dos disciplinas a través del trabajo de campo. Creemos en el potencial cognoscitivo del intercambio entre cine y etnografía, que pueden contaminarse y enriquecerse recíprocamente para producir (y transmitir) un conocimiento más complejo de las realidades que estudiamos. También nos referiremos a los dilemas burocráticos, académicos y éticos que comporta la producción audiovisual y su contribución a la generación de conocimiento sobre los grupos sociales subalternos.

The 21st century as the information age implies that everyone, including students, must be literate in the development and advancement of knowledge-based information and communication technology. That is, students in schools as early as possible must be invited to build 21stcentury knowledge and skills, namely 4C skills. To accommodate this, the learning model must accommodate student centered learning models, one of which is quantum flipped learning (QFL) as a substitute for direct flipped learning (DFL). The aims of this study were 1) to analyze the main and interactive effect between the QFL model vs. the DFL model and students' cognitive involvement on their critical and creative thinking in learning physics. To achieve this goal, experimental research was conducted using a post test only control group design. The population of this research is high school students of class XI SMAN 4 Singaraja, and the sample is 4 classes selected by class random technique. The research data were collected with critical thinking tests, creative thinking tests, and cognitive engagement questionnaires. The research data were analyzed using two-way multivariate analysis of variance. Hypothesis testing was carried out at a significance level of 5%. The results showed that 1) critical thinking and creative thinking of students who studied with the QFL model were higher than students who studied with the DFL model, 2) students who had high cognitive engagement showed critical thinking and creative thinking skills that were not different from students who had low cognitive engagement, 3) there is no interactive effect between the learning model and students' cognitive involvement on critical thinking and creative thinking. The implication of this research is that to achieve optimal critical thinking and creative thinking, physics learning will be better if using the QFL model, students who have low cognitive engagement to be guided and motivated in learning to be able to increase their cognitive engagement in learning, both levels of cognitive involvement students are accommodated by both models.

Abstract— There have been many studies on technology-supported learning based on cognitive theory in the literature. However, little is known about GeoGebra-assisted social cognitive learning in supporting students' reasoning abilities for online learning during the COVID-19 pandemic. This study aims to examine and analyze the differences in the improvement of students' mathematical reasoning abilities who follow GeoGebra-assisted social cognitive learning (Geo-SCL) and GeoGebra-assisted problem-based learning (Geo-PBL). This study used a quantitative method with a quasi-experimental nonequivalent pre-test post-test control-group design. The sample consisted of 70 students from XI SMA Negeri 8 in Bandung, Indonesia. Before and after therapy, research data were collected using a mathematical reasoning test consisting of 5 essay questions. Paired sample t-test analysis and independent t-test were used to answer the research hypothesis. The results of the study concluded that students who studied with Geo-SCL obtained a higher increase in mathematical reasoning abilities than students who studied with Geo-PBL, with the criteria for improving abilities in both classes being in the moderate category. Research findings related to the application of Geo-SCL can be an alternative learning model in online learning situations.
L’événement astronomique du siècle ? Histoire sociale des passages de Vénus, 1874-1882
Authors: Aubin David
Published: September 2022

Les passages de Vénus sont des phénomènes rares (deux par siècle, séparés par 8 ans), permettant de déterminer la distance Terre-Soleil. Ceux du xixe siècle, en 1874 et 1882, donnent lieu à de multiples expéditions en divers lieux du globe, dans le contexte de la colonisation. Le volume s’attache aux retombées sociétales de l’événement. Sont interrogés, entre autres, les rapports conflictuels entre terrain et laboratoire, l’importance accrue de l’image, la montée en puissance des armes savantes.
Sensational Differences: the Case of the Transit of Venus
Authors: Canales Jimena
Published: September 2022

In the nineteenth century, astronomers, physiologists and experimental psychologists noticed that different individuals timed simultaneous phenomena differently. These small “sensational differences”, sometimes referred to as personal equations, augmented considerably in astronomical measurements, in perceptions of movement, and in measurements of rapid phenomena, such as the speed of light. Alarmingly, these differences affected science beyond determinations of time and simultaneity. They appeared in elementary perceptions of lengths, angles, color, and sound. Unlike well-known random errors, they persisted even when observations were repeated and averaged. This paper examines various attempts by scientists to overcome these differences in the determination of the most important constant of celestial mechanics: the solar parallax. It takes us from the famous transit of Venus observations of 1874 to later speed-of-light measurements, tracking fundamental changes in the establishment of measurement-based science.
Conspiracies of Proof and Diversity of Judgement in Astronomy and Physics: On Physicists’ Attempts to Time Light’s Wings and Solve Astronomy’s Noblest Problem
Authors: Staley Richard
Published: September 2022

Amongst the various methods of establishing the distance of the sun to the earth, by the late 19th century measures of the velocity of light had taken a prominent place, apparently trumping transit observations. For the historian of astronomy Agnes Clerke in 1887, such terrestrial measurements had solved (at least provisionally) what Airy called the “noblest problem in astronomy”. By examining experimental work on the velocity of light in France, Britain and (especially) the U.S. in the 1870s and 80s, this paper will explore what this episode reveals about the relations between astronomy and physics in the period. That terrestrial measurements were less costly than transit expeditions was often cited as an advantage, but I will show that once the money scrabbling was over physicists had to work hard —over several years— to prevent their results from embarrassing them.
Reframing the general theory of relativity
Authors: Kunkler Michael
Published: September 2022

The general theory of relativity extends the special theory of relativity to account for gravity (acceleration) and results in the postulation that matter curves spacetime, where gravitation is the embodiment of the spacetime curvature. The curvature of spacetime is modeled using Riemannian
geometry. In this paper, it is proposed that matter rotates spacetime hyperbolically, rather than curves spacetime. As a result, gravitation is the embodiment of the hyperbolic rotation of spacetime. Regions in spacetime that have a larger magnitude of rotation relative to other regions of
spacetime, ceteris paribus, experience stronger gravity, gravitational time dilation, gravitational length contraction, and gravitational frequency shift toward the red (blue) in the electromagnetic waves moving away (toward).
Gravitational waves in the dynamic medium of reference theory
Authors: Pignard Olivier
Published: September 2022

The theory of the dynamic medium of reference (DMR) has already been presented in several articles, in particular, Pignard [Phys. Essays 32, 422 (2019]. The objective of this article is to present gravitational waves within the framework of the DMR theory. For this, an important
relation is established between the gravitational potential and the speed of the flux of the medium. This relation makes it possible to deduce two differential equations verified by the speed of the flux of the medium, one relating to the stationary part and the other to the variational part,
which corresponds to gravitational waves. Solving these two equations provides the speed of the total flux of the medium. An application of the found formulas is carried out to a binary system, and the link with the metric tensor and the fundamental quadratic form of general relativity is
established. Finally, in the DMR theory, gravitational waves are waves that propagate through the medium at the speed of light, not ripples of space-time.

Published: September 2022

This study aims to explain factors that have influenced the e-government service quality in Kuwait during the Coronavirus Disease 2019 (COVID-19) pandemic. Data is collected data from 392 users of the e-government services in Kuwait. The analysis has revealed that having a functional e-government portal allows citizens to complete their transactions and depend heavily on using the e-government services. Moreover, trust, ease of use, and citizen's support were also significant in terms of affecting service quality. The findings also show reliability of content and appearance of information as significant factors. COVID-19 had moderating influence on the relationship between reliability, trust, and citizens' support with e-government service quality. These results imply that citizens care about the functionality of the e-government portal and that it allows them to conduct all the transactions and processes that they need. These findings are useful for government officials to understand the most important elements for e-government service quality and thus design services.
FORMAÇÃO EM MODA NO BRASIL
Authors: Ogushi Milena Mayuri Pellegrino , Sant'Anna Mara Rúbia
Published: September 2022

O presente artigo pretende contribuir para o complexo debate da Moda enquanto objeto de estudo. Neste caminho, optou-se pela análise quali-quantitativa de trabalhos de final de curso da turma formada no ano 2018 da Universidade do Estado de Santa Catarina. A concepção interdisciplinar de campo de Moda, ancorada nas concepções de Frigotto (2002) e Acom e Moraes (2017), bem como a compreensão da pesquisa acadêmica como parte constitutiva de uma formação universitária pautada pela reflexão e exercício crítico, em que Chauí (2001/2003) é baliza teórica, consolidaram o caminho percorrido neste trabalho. Os resultados indicam descompasso na relação entre a composição curricular e as áreas temáticas mais incidentes nas produções analisadas, bem como um perfil utilitário emprestado às disciplinas de cunho técnico. Pensar Moda e educação, contudo, sintoniza a dimensão formativa à missão que assume quando se insere no ensino superior, sobretudo na universidade pública.

Published: September 2022

O artigo apresenta um recorte dos resultados da pesquisa “Uma proposta teórico-metodológica de leitura para o ensino fundamental II mediada pelo gênero discursivo conto”, no âmbito do Mestrado Profissional em Letras (PROFLETRAS) da Universidade Estadual do Norte do Paraná (UENP), que mostra uma metodologia de ensino e como é possível abordar a habilidade leitora por meio do Plano de Trabalho Docente (PTD). Indagou-se: qual a relação entre a aprendizagem da leitura com o PTD, a partir de um conto de Clarice Lispector em turmas do Ensino Fundamental, e como integrar esse gênero às práticas de leitura escolar? Teve como objetivo averiguar se uma proposta de leitura mediada pelo gênero conto, tendo o PTD como instrumento orientador das ações docentes, pode contribuir para a melhoria das práticas de leitura. A metodologia consistiu em uma pesquisa-ação de cunho qualitativo-interpretativo, cujos procedimentos de coleta dedados foram atividades baseadas no PTD ministradas em sala de aula. Os sujeitos da pesquisa foram 23 educandos de uma turma de 9o ano do Ensino Fundamental de uma escola pública estadual de Fortaleza – CE. Os achados da investigação sinalizaram que o PTD articulado ao dialogismo bakhtiniano em sala de aula contribui para a melhoria da leitura dos educandos, que apresentaram uma compreensão responsiva ativa sobre o conto.
