Authors: Moraes Soares Luciana
Published: April 2023

O presente trabalho é fruto dos estudos realizados na disciplina Ética, Democracia e Educação do programa de Mestrado em Educação da Universidad de la Empresa (UDE- Montevideo), a partir da análise das obras Escola e democracia e Educar na era planetária, dos autores Saviani (2012) e Morin (2003) respectivamente, bem como da interlocução entre os teóricos Galeano (2020), Touraine (2011), Calligaris (2021), Barbosa (2005; 2011) e Sibilia (2012). Para a realização deste trabalho, foram utilizados referenciais teóricos em livros e vídeos, disponíveis no Youtube. Este trabalho visa socializar algumas reflexões quanto ao ensino da arte sob a ótica de uma disciplina de resistência problematizadora da contemporaneidade, no contexto de pandemia. Apresenta também alguns desafios e inquietações impostos pela pandemia, sendo que a pandemia nesse cenário, pode ter proporcionado a quebra de paradigma em relação a utilização das tecnologias nos planejamentos didáticos, ao mesmo tempo, em que se configura como uma proposta excludente.

Instruction, Assessment, and Intervention Practices in DMDL: A Multiple Case Study
Authors: Batain May Anne
Published: April 2023

The study aimed to determine the teaching practices of senior high school faculty in an integrated school in Calamba City, Laguna Philippines, offering a digital modular distance learning modality. Specifically, it sought to determine how teachers facilitate instruction, assess learning, and remediate least learned competencies.

            This paper utilized a multiple case study design. The researcher utilized Google Forms in gathering data and probed further by means of Facebook messenger, text messages, and face-to-face interviews. Results revealed that instruction began with the careful crafting of weekly home learning plans (WHLP). Teachers designed video lessons, put up feedback mechanisms, and designed learning activity sheets. In terms of assessment, they combined paper-and-pencil tests with task-based and web-based assessments. Lastly, interventions are done using paper-and-pencil tests, web-based assessments, teacher-made videos, and task-based assessments. Other interventions included home visitations and parent-teacher conferences.

            In conclusion, instruction in the DMDL required careful planning of the WHLP which involved the selection of materials to supplement the teaching-learning process. Assessment in this modality was a combination of traditional and web-based assessments. Interventions, on the other hand, could be academic and non-academic. For academic, further assessments and activities were provided to students whereas home visitations were conducted for those students with other concerns. The researcher recommended for future research the utilization of other research designs to verify the findings of the research in other contexts. Future researchers could consider having larger samples. The researcher also recommended to explore the possibility of DMDL in a post-pandemic scenario.

Authors: Caro Norma Patricia , Ahumada María Inés , Arias Verónica
Published: April 2023

En los procesos de enseñanza y aprendizaje un aspecto relevante es la evaluación del estudiantado, con estrategias innovadoras que tienen como objetivo obtener instrumentos de calidad. En el presente trabajo se pretende verificar el grado de dificultad y capacidad de discriminación de las preguntas que examinan al estudiantado en los conocimientos adquiridos en estadística, a traves de una evaluacion virtual con medios tecnológicos. Para ello, se construyó una prueba con 21 preguntas sobre Inferencia estadística y se la implementó en 124 estudiantes de un curso de Estadística en la Facultad de Ciencias Económicas de la Universidad Nacional de Córdoba, Argentina. A través de un modelo de respuesta al ítem (IRT), con variables de respuesta binaria, para medir los conocimientos adquiridos en el curso de estadística se analizó la relación de cada pregunta del cuestionario con el rasgo latente (conocimientos de estadística) y se determinó el grado de dificultad y discriminación de cada una de las preguntas. Los resultados indican que aquellas preguntas que aportan al constructo, que poseen dificultad media y que son las que más discriminan entre el estudiantado pueden ser retenidas en el cuestionario, ya que permiten además desarrollar otras capacidades que también deben aprenderse, mientras que aquellas preguntas no significativas o muy fáciles y que no discriminan pueden ser reemplazadas con la finalidad de obtener mejores instrumentos de evaluación para lograr los objetivos de aprendizaje. Esta experiencia es de suma utilidad en el contexto de pandemia donde la evaluación pasó de presencial a virtual.

Authors: Devalle Rech Andréia Jaqueline , Giovelli Priscila Michelon , Costa Thaieni Mazetto
Published: April 2023

Este artigo foi baseado nos relatos de experiência de duas acadêmicas do curso de Pedagogia Diurno, da Universidade Federal de Santa Maria (UFSM) - localizada em Santa Maria, Rio Grande do Sul, Brasil - que participaram do Regime de Exercícios Domiciliares Especiais (REDE), adotado durante a suspensão das atividades presenciais da Universidade, por conta da pandemia do Covid-19 (março/2020). Metodologicamente, o artigo configura-se como uma pesquisa qualitativa, do tipo relato de experiência, que se caracteriza pelo caráter descritivo, interpretando e compreendendo sobre fenômenos vividos num dado período histórico. A partir da análise dos relatos de experiências, elencaram-se cinco categorias: "Como aconteceu a mudança do presencial para o remoto"; "Desafios de estudar em casa"; "Dificuldades perante o ensino remoto"; "Metodologias adotadas pelos docentes no ensino remoto: quais foram favorecedoras e quais dificultaram a aprendizagem" e "Adequação quanto ao uso das novas tecnologias da informação e da comunicação para gerir os processos de aprendizagem". Conforme as exposições, percebemos que os discentes têm muito a dizer sobre a pandemia, o ensino remoto, o distanciamento físico, as necessidades, os desafios, as preferências e o como é “ser acadêmico” cotidianamente. Analisamos a importância do REDE durante esse processo de adaptações por parte de ambos, docentes e discentes, sendo uma maneira significativa de, na medida do possível, manter-se vínculos e de potencializar a aprendizagem. Concluímos que as Tecnologias da Informação e Comunicação (TICs) foram essenciais e, apesar dos empecilhos, provocaram inúmeras descobertas de algo que muitas vezes era visto como distante da realidade acadêmica.

Published: April 2023

El deporte es un fenómeno altamente complejo y su estudio puede realizarse desde múltiples perspectivas. Centramos nuestro interés en el deporte de rendimiento y alto rendimiento pensado desde el contexto nacional de Uruguay y su relación con otros ámbitos internacionales. En este artículo de reflexión se pretende presentar y discutir los avances que se vienen desarrollando en las propuestas de enseñanza e investigación universitaria en los factores de rendimiento deportivo: técnica, táctica y preparación física. Desde el punto de vista teórico partimos del marco conceptual de la perspectiva de la complejidad y su relación con el deporte. En esta propuesta de enseñanza profundizamos en estos conceptos en los diferentes niveles de enseñanza universitaria. Así, la integración de esta perspectiva repercute en las propuestas de formación y entrenamiento de los deportistas. En estrecha relación con la enseñanza, la investigación es un aspecto central. Los avances en los estudios del rendimiento deportivo con diferentes metodologías han permitido evolucionar desde propuestas observacionales simple de carácter descriptivo y lineal, a las propuestas actuales que atienden a multiplicidad de factores que afectan al rendimiento, integrando metodologías mixtas e incorporación de modelos de inteligencia artificial. Este avance es relevante en el contexto uruguayo puesto que diferentes propuestas en desarrollo permitirán profundizar y atender a las circunstancias específicas de los deportistas y equipos del país, donde los factores de rendimiento se manifiestan de manera propia y diferenciada tanto en la competición local como internacional.

Published: April 2023

The performance of automatic face recognition (AFR) technology has improved in recent years. As a result, these systems are frequently employed for security and business purposes. a face recognition programme that runs automatically in the background while a university tracks employee attendance. Hence, Smart Attendance with Real Time Face Recognition might be a global solution for managing personnel on a daily basis. The work is incredibly challenging since the critical temporal background subtraction during an image remains a challenge. Real-time face detection is done using easy, quick Principal Component Analysis, which has a high rate of success in identifying the faces found. As a result, we have developed a module in which an employee's attendance will be recorded automatically by recognising their face using face recognition technology. Their face will be saved in the database after this one-time enrollment process. Since enrolling a face is a one-time activity, we need a mechanism. Every employee will have a unique employee ID that is their own roll number. Every employee's presence will be updated within a database. Results of the proposed system demonstrated that it performs better than the manual attendance system. The marking of attendance follows employee identification. This application provides the customer with considerably more solutions and accurate leads than the conventional attendance and leave.

Published: April 2023

Objectives: Total number of avoided endoscopies using Baveno VI criteria is relatively low. Spleen elastography is an attractive tool and when compared with liver stiffness, it better represents the dynamic changes occurring in portal hypertension. The aim of the study was to evaluate spleen shear wave elastography (SWE) in compensated advanced chronic liver disease (cACLD) patients for ruling out the presence of esophageal high-risk varices (HRV). Methods: A total of 401 patients with cACLD were included in this cross-sectional study. The total sample was split into training set (200 patients) and validation set (201 patients). Spleen stiffness was measured with two-dimensional shear wave elastography (2D SWE). Esophageal HRV were defined as large varices (diameter >5 mm) or small varices with red color signs. In the training set, the receiver operating characteristic (ROC) curve was drawn and the area under the curve (AUC) of spleen SWE was assessed. A cutoff value was chosen (highest sensitivity and negative predictive value). In the validation set, the spleen SWE cutoff score and Baveno VI criteria were validated. Results: The prevalence of HRV was 12% in the training set and 13% in the validation set. Spleen SWE had an AUC of 0.89 in ruling out the presence of high-risk esophageal varices (cutoff value of 48.7 kPa, sensitivity of 100%, and specificity of 53%). Validating spleen SWE ≤48.7 kPa in a different cohort of 201 cACLD patients, 55% of screening endoscopies could be avoided without missing any HRV, whereas using Baveno VI criteria only 30% of screening endoscopies could be spared. Conclusion: Spleen SWE ≤48.7 kPa was able to identify cACLD patients who could safely avoid screening endoscopy with good accuracy. Spleen SWE could avoid an additional 25% of screening endoscopies compared to the Baveno VI criteria and no HRV were missed.

Published: April 2023

Introduction

We aimed to provide diagnostic models based on different parameters of placental magnetic resonance imaging (MRI) to detect intrauterine growth restriction (IUGR), as well as the severity of placental insufficiency.

Material and methods

We included 44 foetuses with appropriate weight for gestational age (AGA) and 46 foetuses with documented IUGR, defined as the estimated foetal weight (EFW) below the 10th centile. Using Doppler ultrasound, IUGR cases were divided into 2 groups: 1) IUGR with severity signs: EFW < 3rd centile, or cerebroplacental ratio < 5th centile, or abnormal umbilical/uterine artery pulsatility index; and 2) non-severe IUGR without any of this criterion. For all these participants, placental MRI was performed in the third gestational trimester, and its parameters were compared between AGA and IUGR, as well as between the severe and non-severe IUGR groups. Two diagnostic models consisting of significant predictors were developed, and their performance was investigated with accuracy metrics.

Results

The severity signs were detected in 25 (54.3%) IUGR cases. The diagnostic model for the differentiation of IUGR from AGA revealed an acceptable performance (area under the curve [AUC] of 0.749) and consisted of 2 variables: 1) the largest size of infarct ≥ 25 mm (odds ratio [OR] = 5.01, p = 0.001), and 2) thickness : volume ratio ≥ 0.043 (OR = 3.76, p = 0.027); while, the logistic regression model for detection of the severity signs was even better, with AUC = 0.862, and comprised of 2 predictors: 1) placental infarct percent ≥ 10% (OR = 26.73, p = 0.004), and 2) placental globular shape (OR = 5.40, p = 0.034).

Conclusions

Placental MRI parameters can differentiate IUGR from AGA, and more precisely, assess the severity of placental insufficiency in IUGR foetuses.

Fifteen collections of okra accession were examined for seed physico-chemical properties. Basic seed physical parameters such as seed length, seed width, seed thickness and hundred-seed weight were examined. Chemical parameters such as crude oil%, protein %, fibre, Moisture content%, ash %, calcium mg/100g and carbohydrates were measured and analysed as per recommended methods of the Association of Official Analytical Chemists. Line HSD4899 was identified for best performance for Hundred-seed weight (g) and ash %; Line HSD5021 was identifies as the best performer for carbohydrate %; Line HSD5017 was identified for seed thickness (mm), seed width (mm) and fibre %; HSD6655 were identified for seed thickness (mm), crude oil content % and calcium mg/100g; and line HSD5024 was identified for high protein content. Seed length( mm), seed thickness (mm), seed width (mm), hundred-seed weight (g), sphericity ratio, moisture %, and ash % recorded high heritability estimates and coupled with a high genotypic coefficient of variation suggesting that these traits are under the influence of genetic control and less affected by the environment. Considerable progress can be achieved using phenotypic selection on these traits. Crude protein content has a significant but weak negative correlation with seed width and a moderate negative genotypic correlation with hundred-seed weight. Protein content recorded a significantly moderate negative genotypic

Violence against adolescent girls and young women reported in Turkish newspapers, before one year and in the first year of the Covid-19 pandemic
Authors: NUR Naim , AKOVA İrem
Published: April 2023

Although the negative health consequences on human being caused by the Covid-19 pandemic is reported by the news media globally, its role is not well understood in countries like Turkey. This study provides an assessment over time of the events of Turkish newspaper media reported physical, sexual and lethal violence against adolescent girls and young women. Data for the study was collected through newspaper media reports on physical, sexual and lethal violence that published between March 2019 and March 2021, before one year and in the first year of the Covid-19 pandemic. In 483 (15.3%) of 3165 newspaper media reports the victims were under the age of 18 and the mean age was 13.0±4.5 years. During the study period, physical violence caused by an intimate partner has significantly raised (from 32.6% in 2020 to 40.6% in 2021). Logistic regression analysis also showed that being an intimate partner was the only factor associated with physical violence (OR = 8.1, 95% CI 5.21-12.60, p < 0.001). Given the prevalence of intimate partner violence in Turkey, newspaper media reports highlighting vital issues that may arise during the Covid-19 pandemic can be a good monitoring tool in a low-resource setting. In raising of the public and policymakers’ awareness about the danger consequences of violence against adolescent girls caused by an intimate partner, capacity building of the news media might be a useful approach on this issue.

Published: April 2023

O presente estudo tem como objetivo analisar a produção científica referente aos principais efeitos da hanseníase na percepção corporal e autoestima de mulheres acometidas. Trata-se de um estudo exploratório, do tipo Revisão Integrativa da Literatura (RIL), com abordagem qualitativa. O levantamento bibliográfico foi realizado nas bases de dados LILACS, SciELO e MEDLINE. Após a realização da pesquisa, foram encontrados 96 artigos, resultando em uma amostra final composta por 9 estudos primários.  A análise da literatura indica que a percepção da imagem corporal em mulheres com hanseníase apresenta-se como tema pouco explorado. No entanto, o surgimento de incapacidades ou alterações corporais visíveis podem se traduzir em representações negativas sobre si e discriminação social. As evidências indicam estratégias efetivas que podem ser incorporadas à prática clínica nos serviços de saúde ou associadas às já existentes, para buscar a melhor maneira de lidar com o impacto emocional da experiência, acompanhando o doente e seus contatos, considerando os aspectos psicológicos e sociais que podem influenciar no processo saúde-doença. Sendo assim, há que se pensar na ressignificação de aspectos ligados à vivência com a doença, a cura e o tratamento, além de instrumentalizar os profissionais da saúde para uma abordagem multidimensional.
Carbon monoxide (CO) cycling in the Fram Strait, Arctic Ocean
Authors: Campen Hanna I. , Arévalo-Martínez Damian L. , Bange Hermann W.
Published: April 2023

Abstract. Carbon monoxide (CO) influences the radiative budget and
oxidative capacity of the atmosphere over the Arctic Ocean, which is a
source of atmospheric CO. Yet, oceanic CO cycling is understudied in this
area, particularly in light of the ongoing rapid environmental changes. We
present results from incubation experiments conducted in the Fram Strait in
August–September 2019 under different environmental conditions: while lower
pH did not affect CO production (GPCO) or consumption (kCO) rates,
enhanced GPCO and kCO were positively correlated with coloured
dissolved organic matter (CDOM) and dissolved nitrate concentrations,
respectively, suggesting microbial CO uptake under oligotrophic conditions
to be a driving factor for variability in CO surface concentrations. Both
production and consumption of CO will likely increase in the future, but it
is unknown which process will dominate. Our results will help to improve
models predicting future CO concentrations and emissions and their effects
on the radiative budget and the oxidative capacity of the Arctic atmosphere.
Connecting CSR theory and LPJmL 5.3 to assess the role of environmental conditions, management and functional diversity for grassland ecosystem functions

Published: April 2023

Abstract. Forage supply and soil organic carbon storage are two important ecosystem functions of permanent grasslands, which are determined by climatic conditions, management and functional diversity. However, functional diversity is not independent of climate and management, and it is important to understand the role of functional diversity and these dependencies for ecosystem functions of permanent grasslands. Especially since functional diversity may play a key role in mediating impacts of changing conditions. Large-scale ecosystem models are used to assess ecosystem functions within a consistent framework for multiple climate and management scenarios. However, large-scale models of permanent grasslands rarely consider functional diversity. We implemented a representation of functional diversity based on the CSR theory and the global spectrum of plant form and function into the LPJmL dynamic global vegetation model forming LPJmL-CSR. Using a Bayesian calibration method, we parameterised new plant functional types and used these to assess forage supply, soil organic carbon storage and community composition of three permanent grassland sites. These are a temperate grassland, a hot and a cold steppe for which we simulated several management scenarios with different defoliation intensities and resource limitations. LPJmL-CSR captured the grassland dynamics well under observed conditions and showed improved results for forage supply and/or SOC compared to LPJmL 5.3 at three grassland sites. Furthermore, LPJmL-CSR was able to reproduce the trade-offs associated with the global spectrum of plant form and function and similar strategies emerged independent of the site specific conditions (e.g. the C- and R-PFTs were more resource exploitative than S-PFTs). Under different resource limitations, we observed a shift of the community composition. At the hot steppe for example, irrigation led to a more balanced community composition with similar C-, S- and R-PFT shares of above-ground biomass. Our results show, that LPJmL-CSR allows for explicit analysis of the adaptation of grassland vegetation to changing conditions while explicitly considering functional diversity. The implemented mechanisms and trade-offs are universally applicable paving the way for large-scale application. Applying LPJmL-CSR for different climate change and functional diversity scenarios may generate a range of future grassland productivity.
Marsh induced backwater: the influence of non-fluvial sedimentation on a delta's channel morphology and kinematics
Authors: Sanks Kelly , Shaw John , Zapp Samuel , Silvestre José , Dutt Ripul , Straub Kyle
Published: April 2023

Abstract. We investigate the interaction of fluvial and non-fluvial sedimentation on the channel morphology and kinematics of an experimental river delta. We compare two deltas: one that evolved with a proxy for non-fluvial sedimentation (treatment experiment) and one that evolved without the proxy (control). We show that the addition of the non-fluvial sediment proxy alters the delta's channel morphology and kinematics. Notably, the flow outside the channels is significantly reduced in the treatment experiment and the channels are deeper (as a function of radial distance) and longer. We also find that the treatment channels have the same width from the entrance to the shoreline, while the control channels get narrower as they approach the shore. Interestingly, the channel beds in the treatment experiment often exist below sea level in the terrestrial portion of the delta top creating a ~0.7 m reach of steady, nonuniform backwater flow. However, in the control experiment, the channel beds generally exist at or above relative sea level, creating channel movement resembling morphodynamic backwater kinematics and topographic flow expansions. Differences between channel and far-field aggradation produce a longer channel in-filling timescale for the treatment as compared to the control, suggesting that the channel avulsions triggered by a peak in channel sedimentation occur less frequently in the treatment experiment. Despite this difference, the basin-wide timescale of lateral channel mobility remains similar. Ultimately, non-fluvial sedimentation on the delta top plays a key role in the channel morphology and kinematics of an experimental river delta, producing channels which are more analogous to channels in global river deltas, and which cannot be produced solely by increasing cohesion in an experimental river delta.
Array processing in cryoseismology

Published: April 2023

Abstract. Seismicity at glaciers, ice sheets and ice shelves provides observational constraint of a number of glaciological processes. Detecting and locating this seismicity, specifically icequakes, is a necessary first step in studying processes such as basal slip, crevassing, and imaging ice fabric, for example. Most glacier deployments to date use conventional seismic networks, comprised of seismometers distributed over the entire area of interest. However, smaller aperture seismic arrays can also be used, which are typically sensitive to seismicity distal from the array footprint and require a smaller number of instruments. Here, we investigate the potential of arrays and array-processing methods to detect and locate seismicity in the cryosphere, benchmarking performance against conventional seismic network-based methods. We also provide an array-processing recipe for cryosphere applications. Results from an array and network deployed at Rutford Ice Stream, Antarctica, show that arrays and networks both have strengths and weaknesses. Arrays can detect icequakes from further distances whereas networks outperform arrays for more comprehensive studies of a process within the network extent, due to greater hypocentral constraint and a smaller magnitude of completeness. We also gain new insights into seismic behaviour at Rutford Ice Stream. The array detects basal icequakes in what was previously interpreted to be an aseismic region of the bed, as well as new icequake observations at the ice stream shear-margins, where it would be challenging to deploy instruments. Finally, we make some practical recommendations for future array deployments at glaciers.

Abstract. The widely-used open-source community Noah-MP land surface model (LSM) is designed for applications ranging from uncoupled land-surface and ecohydrological process studies to coupled numerical weather prediction and decadal global/regional climate simulations. It has been used in many coupled community weather/climate/hydrology models. In this study, we modernize/refactor the Noah-MP LSM by adopting modern Fortran code and data structures and standards, which substantially enhances the model modularity, interoperability, and applicability. The modernized Noah-MP is released as the version 5.0 (v5.0), which has five key features: (1) enhanced modularization and interoperability by re-organizing model physics into individual process-level Fortran module files, (2) enhanced data structure with new hierarchical data types and optimized variable declaration and initialization structures, (3) enhanced code structure and calling workflow by leveraging the new data structure and modularization, (4) enhanced (descriptive and self-explanatory) model variable naming standard, and (5) enhanced driver and interface structures to couple with host weather/climate/hydrology models. In addition, we create a comprehensive technical documentation of the Noah-MP v5.0 and a set of model benchmark and reference datasets. The Noah-MP v5.0 will be coupled to various weather/climate/hydrology models in the future. Overall, the modernized Noah-MP will allow a more efficient and convenient process for future model developments and applications.

Abstract. Climate warming accelerates the global water cycle. However, the relationships between climate warming and hydrological processes in the alpine arid regions remain unclear. Herein, high spatiotemporal resolution sampling of surface water and groundwater was performed at the Qaidam Basin, an extremely arid area in the northeastern Tibetan Plateau. Stable H-O isotopes and radioactive 3H isotopes were combined with atmospheric simulations to examine climate change and hydrogeological characteristics. The surface water heavy isotopes enrich during the wet season and deplete during the dry season. The contribution of precipitation to river discharge was considerably higher in the eastern region of the basin (approximately 45 %) than in the central and western regions (10 %–15 %). The H-O isotopic compositions showed a gradually negative spatial pattern from the west to the east in the Eastern Kunlun Mountains water system; a reverse pattern occurred in the Qilian Mountains water system. This distribution pattern was jointly regulated by the westerly water vapor transport intensity and local hydrothermal conditions. Increased precipitation and cryosphere shrinkage caused by climate warming mainly accelerated basin groundwater cycle. In the eastern and southwestern Qaidam Basin, precipitation and ice/snow meltwater infiltrate structural channels that favor water flow, such as fractures and fissures, facilitating rapid seasonal groundwater recharge and increased terrestrial water storage. However, under future increases in precipitation in the southwestern Qaidam Basin, compensating for water loss from long-term melting of ice and snow will be challenging, and the total water resources may show an initially increasing and then decreasing trend.

Abstract. Infrared attenuated total reflection (ATR) spectroscopy is a common laboratory technique for the analysis of highly absorbing liquids and solids, and a variety of ATR accessories for laboratory FTIR spectrometers are available. However, ATR spectroscopy is rarely found in industrial processes, where compact, robust, and cost-effective sensors for continuous operation are required. Here, narrowband photometers are more appropriate than FTIR instruments. We show the concept and implementation of a compact Si-based ATR module with a four-channel microelectromechanical systems (MEMS) detector. Measurements of liquid mixtures demonstrate the suitability for applications in the chemical industry. Apart from sapphire (for wavelengths below 5 µm) and diamond (extending to the far-infrared region), most materials for ATR
elements do not have either high enough infrared transmission or sufficient
mechanical and chemical stability to be exposed to process fluids, abrasive
components, or aggressive cleaning agents. However, using diamond coatings
on Si improves the stability of the sensor surface. In addition, by proper
choice of incidence angle and coating thickness, an enhancement of the ATR
absorbance is theoretically expected and demonstrated by first experiments
using a compact sensor module with a diamond-coated Si ATR element.
L’Afrique est-elle toujours enfermée dans la caverne de « la conscience occidentale du Nègre » ?
Authors: MADJINZE-MA-KOMBILE Ariande Cindy , KOUMBA Rolph Roderick
Published: April 2023

Les chapitres introductif et de conclusion de Tels des astres éteints (2008) de Léonora Miano déconstruisent le mythe de l’Afrique perçue comme l’univers-type des humanités subalternes. Curieusement, cette perception essentialiste semble étroitement liée à « la conscience occidentale du Nègre », laquelle instaure « la politique de la différence » que la critique récuse. Celle-ci apparaît comme une absurdité car elle instrumentalise la couleur de la peau et les maux dont souffre l’Afrique.

On January 18, Microsoft revealed its $68.7 billion deal to acquire videogame publisher Activision Blizzard. The acquisition was pitched as an investment towards “metaverse platforms” that gaming would play a key role in developing. Journalists speculated about the increasing consolidation of the videogame industry and whether blockbuster franchises would be locked into Microsoft’s platforms and subscription services. Commentary on the metaverse weighed in on how toxicity and harassment in game industry workplaces such as Activision Blizzard might relate to issues of trust and safety in virtual worlds such as Meta’s Horizon Worlds. Seemingly above the fray of platform strategy, market speculation, and corporate scandal, New Yorker writer Kyle Chayka (2022) tweeted as a matter of fact: “video game infrastructure and tools are increasingly going to take over all digital platforms”. This panel contextualizes discussions about the business and aesthetics of 3D platforms in the infrastructural work of game engines, which routinely integrate databases, file formats, web protocols, and translational algorithms. We trace public debates and corporate statements over representation and governance, equity and inclusion (Bosworth 2021) to the techniques, technologies, and practices that enable massive real-time 3D digital spaces to flow and transact. We also highlight the growing intertwinement between game engine development companies and related content ecosystems, such as the Epic Games Store and the Unreal Engine, and Epic’s and Unity’s Asset Stores. This panel investigates how digital systems are designed to regulate technical interoperability and its implications for creative practice and cultural production. Together, these papers map how power and capital become centralized and distributed throughout the back end of the metaverse, and politicize how social practices and subjectivities are negotiated through technological architecture.
MOBILE MEDIA DURING THE PANDEMIC: FOUR SCENARIOS TO HELP US IMAGINE A MOBILE MEDIA FUTURE TOWARDS LIBERATION

Together, our projects pose the question of what else can be possible as a way to rearrange the power relations that have contributed to the asymmetric flows of information and resources to some instead of others. We are inspired by indigenous scholars’ claim that “decolonization is not a metaphor” because liberation should not be a metaphor: it should be a possibility.

We, panelists, hope to engage conversations that address the future of the internet, especially the future of mobile communication with the lessons learned from studies. Panelists offer a close reading of four scenarios: in South Korea among residents whose locative data tell a story about their comings and goings, among International Exchange Students mobile media use during the on-set of travel bans, in China among rural-to-urban female migrant workers, and in Brazil among those who used the Unified Slum Dashboard to called attention for proper government intervention. Among our research methods are interviews, observations, content analysis, and case study to bring attention to and make institutional space for voices and accounts of community engagement that have been marginalized or overlooked. Our findings share a common theme that mobile media simultaneously can liberate and complicate our mobility choices, especially during a global pandemic, but that it can be a civic media in which liberation can be possible through more careful policies that take minoritized experiences into consideration for future policies.
WALKSHOPS – TESTING A LOW THRESHOLD METHODOLOGY FOR PARTICIPATORY CITY MAKING
Authors: Breuer Jonas , Van Zeeland Ine , Pierson Jo
Published: April 2023

This research is about an inclusive, participatory methodology for smart city research: walking in the ‘datafied’ city. So-called walkshops facilitate experiences of and discussion about the environment in which social challenges arise, together with urban dwellers who may perceive them in different ways than decision-makers. We are investigating if walkshops provide a low-threshold methodology for meaningful involvement of all urban dwellers in technological decision-making, with a specific interest in the involvement of societal groups that are vulnerable.

The General Data Protection Regulation (GDPR), for example, highlights the importance of transparency, accountability, and control of all technology users over the processing and use of their personal data. This includes so-called vulnerable data subjects. In smart, datafied cities, personal data protection provisions and rights could contribute to empowering urban dwellers. However, taking self-determined decisions regarding legal provisions and complex technical systems is often difficult, and nigh impossible for some. Despite the legal efforts to empower all data subjects vis-à-vis the processing of their personal data, inherent power imbalances remain, and the provisions hardly reach some groups. An important aim of the walkshop methodology is therefore to be inclusive and attractive for anyone.

Against this backdrop, we describe how the methodology was tested, and evaluated during eighteen walks in the cities of Brussels, Gent, and Leuven. Evaluations by researchers, participants, and partner organisations, showed very promising results despite some methodological challenges (e.g. participant recruitment). Walkshops show the potential for socially relevant empirical work that creates win-win situations for researchers, public partners, and citizenries.
