Published: January 2023

Previous studies demonstrate the critical importance of non-coding RNAs interfacing with chromatin-modifying machinery resulting in promoter-enhancer-based gene regulation and raise the possibility that many other enhancer-like RNAs may operate via similar mechanisms. Critically, more than 80% of the disease-linked variations identified in genome-wide studies are located in the non-coding regions of genomes, especially non-coding RNA, suggesting non-coding RNAs are relevant to disease. Thus, a critical path forward for understanding non-coding RNAs' role, especially long non-coding RNAs, is to understand the genomic regions' transcriptional regulation, especially non-coding regions. Here, we developed a user-friendly R package called SomaGene for studying and identifying enhancer-like non-coding RNAs with enriched somatic mutations in the cancer genome. SomaGene accepts different genomic variants (whole genome/exome somatic point mutations, structural variations, copy number variations) to identify those RNAs that significantly mutated in diseases (e.g., cancer). It then uses multiple publicly available genomics and epigenetics datasets including ENCODE epigenomics annotations, FANTOM5 tissue-specific expression profiles, disease-associated genome-wide association SNPs, and tissue-specific eQTL pairs to identify those RNAs with potentially enhancer function. SomaGene, as a powerful R package, can provide the opportunity to cancer scientists to study the roles of non-coding RNAs in different cancer genomes.

Authors: Piretti Luca , Pappaianni Edoardo , Garbin Caludia , Rumiati Raffaella Ida , Job Remo , Grecucci Alessandro
Published: January 2023

Self-conscious emotions, such as shame and guilt, play a fundamental role in regulating moral behavior and in promoting the welfare of the society. Despite their relevance, the neural bases of these emotions are uncertain. In the present meta-analysis, we performed a systematic literature review in order to single out functional neuroimaging studies on healthy individuals specifically investigating the neural substrates of shame, embarrassment and guilt. Seventeen studies investigating the neural correlates of shame/embarrassment, and seventeen studies investigating guilt brain representation met our inclusion criteria. The analyses revealed that both guilt and shame/embarrassment were associated with the activation of the left anterior insula, involved in emotional awareness processing, and arousal. Guilt specific areas were located within the left temporo-parietal junction, which is thought to be involved in social cognitive processes. Moreover, specific activations for shame/embarrassment involved areas related to social pain (dorsal anterior cingulate, insula, thalamus), behavioral inhibition (premotor cortex) networks. This pattern of results might reflect distinct action tendencies associated with the two emotions.
Molecular Pathways in Staphylococcus Aureus Endocarditis: a Systematic Review
Authors: Nappi Francesco , Avtaar Singh Sanjeet Singh
Published: January 2023

Staphylococci sp. have become the primary pathogens implicated in infective endocarditis, especially within high-income nations. Coupled with the increasing burden of healthcare with aging populations and the protracted course the infections may take, these infections contribute to a significant challenge for healthcare. A systematic review was conducted using relevant search criteria from PubMed, Ovid’s version of MEDLINE, and EMBASE, and data were tabulated from randomized controlled trials (RCT), observational cohort studies, meta-analysis, and basic research articles. The review was registered with the OSF register of systematic reviews and followed the PRISMA reporting guidelines. 35 studies met the inclusion criteria and were included in the final systematic review. The role of Staphylococcus aureus and its interaction with the protective shield and host protection functions is identified and highlighted in several studies. The interaction between infective endocarditis pathogens, vascular endothelium, and blood constituents is also explored giving rise to the potential use of antiplatelets as preventative and/or curative agents. Several factors allow Staphylococcus aureus infections to proliferate within the host with numerous promoting and perpetuating agents. The complex interaction with the hosts' innate immunity also potentiates its virulence. Ameliorating these molecular pathways may serve as a therapeutic avenue for the prevention and treatment of these infections in the near future.
Approximate Priority Hybrid 3DNoC Buffered-Bufferless Router
Authors: Savva Savvas , Tatas Konstantinos , Kyriacou Costas
Published: January 2023

This paper introduces a novel 3D NoC router that combines buffered and bufferless routing with approximate priority comparison when deflecting flits. Our proposal is a modification of an asymmetrical router that is buffered in the z dimension ports and bufferless in the x and y dimension ports. Flits that request output ports in the x and y dimensions are granted or deflected based on approximate, instead of accurate, priority comparison. Experimental results show that the proposed router, besides effectively combining the advantages of both buffered and bufferless routers, it achieves additional performance and area gains due to the reduced logic required for approximate priority comparison in flit deflections. Experimental results using synthetic and realistic traffic show that the proposed router begins to saturate at a sifnificantly higher injection rate than a bufferless router, but at a slightly lower injection rate than when using accurate priority comparison. Furthermore, the proposed router achieves higher clock frequencies and reduced area compared to the simpler permutation network.
The Environmental Kuznets Curve hypothesis for Colombia: impact of economic development on greenhouse gas emissions and ecological footprint
Authors: Acevedo Jorge A , Valencia Carlos Felipe , Valencia Carlos Darío
Published: January 2023

Climate change has become a major concern for developing countries given the risk that it posses on energy and food independence, and on general productivity. Despite having an energy system with low carbon intensity when compared to other Latin American countries, Colombia is already facing climate change impacts and requires urgent efforts to mitigate them. As a developing country, the challenge is bigger as policies for economic growth should be in line with the global commitment of reducing greenhouse gas emissions. With the aim of contributing to the design of climate policies, this study assesses the impact of economic development on the environment by examining the validity of the Environmental Kuznets Curve hypothesis for Colombia. Statistically validated and stable autoregressive distributed lag models are estimated for three different environmental indicators: carbon dioxide emissions, methane emissions, and ecological footprint. Moreover, the effects of other variables such as urbanization, foreign direct investment, value added of agricultural and industrial sectors, and energy use are analyzed with dynamic simulations. Empirical evidence supports a long-run equilibrium relationship among investigated variables and the existence of an inverted U-shaped EKC relationship between Gross Domestic Product (GDP) and methane emissions, and GDP and ecological footprint. Shifting to renewable energy sources and leveraging the use of cleaner technologies in agricultural and industrial sectors are found to be key for economic growth without harming the environment.

Published: January 2023

The lethal combination involving TB and HIV, known as 'syndemic’ diseases synergistically act upon one another to magnify the disease burden. Individuals on ART are at risk of developing TB-associated immune reconstitution inflammatory syndrome (TB-IRIS). The underlying inflammatory complication includes the rapid restoration of immune responses following ART eventually leading to exaggerated inflammatory responses to MTB antigens. TB-IRIS continues to be a cause of morbidity and mortality among HIV/TB coinfected patients initiating ART, and although significant quantum of knowledge has been acquired on the pathogenesis of IRIS, the underlying pathomechanisms and identification of a sensitive and specific diagnostic markers still remain a grey area of investigation. Here, we reviewed the latest research developments in IRIS immunopathogenesis, and outlined the modalities to prevent and manage strategies for better clinical and diagnostic outcomes for IRIS.
Stability and Resolution Analysis of the Wavelet Collocation Upwind Schemes for Hyperbolic Conservation Laws
Authors: Yang Bing , Wang Jizeng , Liu Xiaojing , Zhou Youhe
Published: January 2023

A system of wavelet collocation upwind schemes is constructed for solving hyperbolic conserva-tion laws based on a class of interpolation wavelets. The bias magnitude and symmetry factor are defined to depict the asymmetry of the adopted scaling basis function in wavelet theory. Effects of characteristics of the scaling functions on the schemes are explored based on numerical tests and Fourier analysis. The numerical results reveal that the stability of the constructed scheme is af-fected by the smoothness order, N, and the asymmetry of the scaling function. The dissipation analysis suggests that schemes with Neven have negative dissipation coefficients, leading to unstable behaviors. Only scaling functions with Nodd and bias magnitude of 1 can be used to construct stable upwind schemes due to the non-negative dissipation coefficients. Resolution of the wavelet scheme tends to the spectral resolution as the order of accuracy of the scheme in-creases.
Crater Formation under Extreme Space Weather Conditions
Authors: Gable Jacob , Bagashov Eugene
Published: January 2023

We consider an alternative hypothesis of crater formation -- through an electric discharge machining (EDM) of the celestial bodies' surfaces. The source of the energy and the current itself may lie in the plasma infalling on a celestial body (from an extremely strong solar outburst or a nearby supernova). This mechanism may have been even more important than impact cratering in the early Solar System, with potential implications to the history of the dynamics of the System itself and solar activity in particular. In this light, the conclusion that shocked and metamorphosed minerals found within crater sites are evidence of hypervelocity impacts might be reconsidered. There are ambiguities that remain among sources of mineralogical formations. This study is ongoing with details of investigations supporting a new approach to crater formation not yet exhausted. Apart from mineralogical analysis and theoretical considerations regarding the large scale crater formation, we present a description of experimental studies of EDM acting at low pressures. Experimental results are made with crude setups and could easily be replicated on a larger scale with valuable research potential, as there is a well understood relation between the crater size and the energy needed for its production.

Published: January 2023

Cervical cancer is mostly diagnosed cancer of women worldwide and the second most common cancer among middle-aged women in Bangladesh. Knowledge and perception of women are considered one of the major components of prevention strategy. We carried out this survey to assess the existing knowledge level of students and their perception to the role of vaccination in preventing cervical cancer. The participants were female undergraduate students studying Public Health in a university in Chattogram city of Bangladesh. A total of 275 female students were interviewed through prescribed questionnaire possessing questions on basic information of cervical cancer, its causal agent, risk factors, prevention methods, and vaccination. We marked the responses of participants with zero for wrong answer and one for every correct answer and ranked the knowledge level of students. The mean age of study participants was 20.68 years. In total, 69.1% students possessed poor knowledge whereas, 30.9% had good knowledge. The country of students has significant association with their level of knowledge. Most of the students got information on cervical cancer from traditional media (49.8%) and doctor (30.9%) and the effect of these two sources was statistically significant on the knowledge level of students. Students mostly identified vaccination (21.1%) and Gynecological examination (14.39%) as preventing methods. However, 65.5% of them acknowledge that vaccines cannot prevent this cancer and 33.4% believe in different risks of vaccine. Although students have heard of cervical cancer the overall knowledge was insufficient and perceived negative concepts about cancer vaccine. Therefore, we recommend the initiation of educational programs on basic reproductive health and health seeking behaviour targeting young women to successfully control and prevention of this life-threatening health problem.

Published: January 2023

Ophelia syndrome is characterized by the coincidence of severe neuropsychiatric symptoms, classical Hodgkin lymphoma, and the presence of antibodies to the metabotropic glutamate 5 receptor (mGluR5). Little is known about the pathogenetic link between these symptoms and the role that anti-mGluR5-antibodies play. We investigated lymphoma tissue from patients with Ophelia syndrome and with isolated classical Hodgkin lymphoma by quantitative immunocytochemistry for mGluR5-expression. Further, we studied the L-1236, L-428, L-540, SUP-HD1, KM-H2, and HDLM-2 classical Hodgkin lymphoma cell lines by FACS and Western blot for mGluR5-expression, and by transcriptome analysis. mGluR5 surface expression differed significantly in terms of receptor density, distribution pattern, and percentage of positive cells. Highest expression levels were found in the L-1236 line. RNA-sequencing revealed more than 800 genes that were higher expressed in the L-1236 line in comparison to the other classical Hodgkin lymphoma cell lines. High mGluR5-expression was associated with upregulation of PI3K/AKT and MAPK pathways and of downstream targets (e.g. EGR1) known to be involved in classical Hodgkin lymphoma progression. Finally, mGluR5 expression was increased in the classical Hodgkin lymphoma-tissue of our Ophelia syndrome patient in contrast to five classical Hodgkin lymphoma-patients without autoimmune encephalitis. Given the association of encephalitis and classical Hodgkin lymphoma in Ophelia syndrome, it is possible that mGluR5-expression on classical Hodgkin lymphoma cells not only drives tumor progression but also triggers anti-mGluR5 encephalitis even before classical Hodgkin lymphoma becomes manifest.

Influence of the Impact Angle on Machining in Powder Jet Processing
Authors: Kuji Chieko , Izumita Kuniyuki , Shimada Keita , Mizutani Masayoshi , Sasaki Keiichi , Kuriyagawa Tsunemoto
Published: January 2023

Powder jet machining is a blast machining process in which micrometer-order particles are projected onto a workpiece at near-supersonic speeds, to remove the workpiece (abrasive jet machining (AJM)) or to deposit the particles (powder jet deposition (PJD)). We report a novel dental treatment method for powder jet machining using hydroxyapatite, which is the main component of teeth, as deposited particles. The surfaces and interdental spaces of human teeth are not only flat, but also have complex groove structures. However, PJD and AJM exhibit impact-angle-dependent machining phases. Therefore, it is necessary to investigate the effect of the particle impact angle on machining, before dental treatment. Furthermore, because machining interacts not only with the particle impact angle but also with the particle impact velocity, a comprehensive investigation of the effects of the machining parameters is required, for delineating the phase-transition conditions. Accordingly, in this study, we conducted machining experiments using hydroxyapatite particles (particle diameter, 2.16 μm) and four different blasting angles of 30°, 45°, 60°, and 90°, to infer the machining amount. Machining efficiency was evaluated based on the amount of machining. The impact angles and velocities of the particles were calculated using computational fluid dynamics (CFD). Three-dimensional process mapping was performed using the machining amount, particle impact angle, and particle impact velocity, obtained from the experiments and CFD calculations. The results showed that PJD crossed to AJM at the impact angle of approximately 60°. Moreover, PJD exhibited high processing efficiency for impact angles above 60° and impact velocities in the 280–310 m/s range. In contrast, AJM exhibited high processing efficiency for impact angles below approximately 35° and impact velocities above 310 m/s.

Published: January 2023

The demand for optical glass lenses is rising owing to the increase in image resolution. Optical glass is a hard and brittle material. Thus, an efficient and precise grinding method is required for optical glass to improve lens quality and productivity. There are a few methods of producing crack-free machined surfaces; however, they provide only limited grinding efficiency. To resolve this issue, the authors’ group has proposed the reaction-induced slurry-assisted (RISA) grinding method, which expands the range of ductile-regime grinding by utilizing the chemical–mechanical action of a cerium oxide slurry. In this study, the grinding performance of RISA grinding is experimentally evaluated for different pH levels. The results are compared using Tukey’s test, where surface roughness is considered as the characteristic value and the pH value as the analyzed factor. The result shows that RISA grinding efficiently produces a high-quality surface when the slurry is alkaline. The adhesion of cerium oxide abrasives to the wheel in RISA grinding follows the same mechanism as slurry aggregation. In addition, adhesion is more likely to occur when the alkalization of the slurry promotes aggregation. The tank in the slurry supply unit is replaced with a rotating tank to ensure stable RISA grinding with a highly aggregable slurry while preventing aggregation. The performance evaluation shows that a high-quality surface with a surface roughness of less than 10 nm in most parts is obtained. Moreover, the critical depth of cut stably increases by a factor of 5.8.

Exploring Sociolects in Audiovisual Texts. A New Concept?
Authors: Martínez Sierra Juan José
Published: January 2023

This article is based on a consideration of the audiovisual text as a system in which different signifying codes converge, giving it a multimodal nature. Studies on the nature of the audiovisual text have addressed a multitude of aspects to date, although there are still concepts to be explained within the audiovisual paradigm. One such aspect has to do with varieties of language, specifically with the notion of sociolect. After a review of the literature, fragments of television sitcoms will be analysed to observe the possible audiovisual nature of the given sociolect. Specifically, it will be illustrated how language levels, slang, and scientific-technical language deal with audiovisual humour. The idea will be fostered that in this type of text, sociolects go beyond the linguistic scope and connect with the aural and visual dimensions. Accordingly, phenomena such as humour can be constructed thanks to elements that surpass a purely linguistic conception of sociolects.

Remote Interpreting in Spain after the Irruption of COVID-19: A Mapping Exercise
Authors: Lázaro Gutiérrez Raquel , Nevado Llopis Almudena
Published: January 2023

Remote interpreting, particularly telephone interpreting, was implemented in Spain less than 20 years ago and, since then, it has become increasingly common. Its use has even increased during the last months, due to COVID-19 circumstances and the subsequent growth of telecommuting. This paper aims at mapping remote interpreting services in Spain. With that purpose, structured qualitative interviews were conducted with representatives of the six main Spanish companies offering these services. The results show a diffusion of telephone interpreting across the country and an incipient presence of video-link interpreting. Nevertheless, more attention to quality performance and working conditions should be paid.

Finding ethics in and out of codes: ethical dilemmas faced by healthcare interpreting student interns
Authors: Álvaro Aranda Cristina
Published: January 2023

Establishing a code of ethics is a requirement an occupation must meet to become a full-fledged profession. In healthcare interpreting, several professional associations have published their own codes. Students are introduced to these codes in the classroom, but when they access the profession they often face ethical dilemmas that may overlap with their professional obligations. This paper explores a series of ethical dilemmas faced by students that first encounter the workplace as part of an internship programme. Drawing on participant observation and post-encounter interviews, we identify ethical dilemmas, describe the interns’ behaviour, and illustrate the rationale behind their choices. This allows us to isolate factors that hinder participants from strict adherence to codes of ethics (i.e., the theory-practice gap, contextual restrictions, and human emotion). In the light of results obtained, we encourage trainers and interpreters to develop critical ethical thinking in different healthcare scenarios to facilitate assessing the consequences of (not) following a code of ethics.

Are we teaching what they need? Going beyond employability in Translation Studies
Authors: Sánchez Ayuso Pablo , Haro Soler María del Mar , García de Quesada Mercedes
Published: January 2023

As lecturers and researchers in translation and interpreting, we are aware of the need to design curricula so that students are well equipped, and able to respond to the requirements of modern society. In the world today, there is an evident gap between what is actually taught in higher education and what should be taught to meet student needs. Even though various studies have already focused on the impact of constructs, such as self-regulation, empathy, or creativity, on performance quality, there is still a long way to go. In order to bridge this gap and highlight the role of the university as a transformational agent, our study uses LifeComp, the European framework for the personal, social, and learning to learn key competence. The objective of this research was firstly to discover the transversal competences that are most highly valued by employers in the language industry sector; and secondly, to identify the competences that need more attention in curricula. For this purpose, a questionnaire-based study was designed and administered to translation companies based in Spain. The results obtained indicate that these competences are necessary to foster employability as well as real wealth creation in a lifelong learning context. This study is part of a broader project within the LifeComp framework, in which a competence-based psycho-educational intervention was designed and is now integrated in the translation and interpreting degree programme at the University of Granada (Spain).

Cavidad idiopática de Stafne: una revisión de literatura
Authors:   , Cruces Valdivia Alexandra Gabriela
Published: January 2023

En 1942, el Dr. Edward Stafne presentó una serie de casos con características radiográficas de imágenes radiolúcidas con forma redondeada y bien delimitadas que asemejaban patologías maxilares, que tenían algunos aspectos en común como la ubicación cercana al ángulo mandibular y la relación con la base mandibular, a los que se refirió como defecto óseo. A este defecto se le conocería más adelante con diferentes nombres. Clínicamente es asintomática, no suele palparse intraoralmente ni presentar signos extraorales. Por ello, en la mayoría de los casos será un hallazgo radiológico accidental, el cual se presenta como una imagen radiolúcida delimitada, elíptica o redondeada, su diámetro varía de 1 a 3 centímetros, aproximadamente, y está delimitada por una osteocondensación en sus límites anteroinferiores. Según su ubicación, es clasificada en tres variantes; anterior, posterior y de rama. Se debe considerar esta entidad como una variante de normalidad y asociarla con diagnósticos alternativos. Por ello, esta revisión brinda información sobre su historia y sus características generales y radiográficas, con el fin de contribuir a una mejor visión respecto de este tipo de hallazgos.

Sin embargo, la capacidad de su planta es insuficiente. Una alternativa tecnológica eficiente para incrementar la capacidad de tratamiento y cumplir con las normativas ambientales vigentes es el tratamiento de electrocoagulación (EC). El tratamiento se basó en la construcción de una celda tipo batch de 30 L (representa el 0.5% de capacidad real la PTSB); donde se instalaron 20 electrodos en distribución paralela (10 de Al y 10 de Fe) y, se aplicó de 6 a 12 A de intensidad de corriente al tratamiento, durante tiempo de 10, 20 y 30 min a un total de 28 muestras, siendo cuatro de ellas controles y el resto tratamientos. Los resultados obtenidos permitieron determinar que los factores que influyen en la eficiencia de la EC fueron el tiempo de aplicación del tratamiento (30 min) y la densidad de corriente (12 A). La experimentación y aplicación de la EC demostró tener un resultado óptimo para ser implementado como un tratamiento complementario en la PTSB, lográndose una reducción de concentración de 98.1% de As, 86.26% de Cd, 91.37% de Pb y 88.88% de Fe, un 94.55% de DBO5, 99.99% de coliformes termotolerantes (CTT), y una disminución de conductividad de 439.4 a 36. 33 µS/cm; mientras que el resto de parámetros variaron entre 4.6 y 8.8 mg/L el oxígeno disuelto, entre 6.5 y 7.8 el pH, y la temperatura Δ 0.8 y Δ 6.2 °C.

The growth of Islamic insurance in Indonesia has experienced significant growth. On the other hand, the market share of Islamic insurance in Indonesia is still at 5%. As a country with a Muslim majority population, it is essential to know the factors that influence the interest of Muslims to adopt Sharia insurance in Indonesia. In this study, the author tries to analyze the factors that influence a Muslim's interest in adopting Sharia insurance in Indonesia. This study uses the theory of the planned behavior approach. The study results show that the variables of attitude, subjective norm, and perceived behavioral control have a positive and significant influence on the interest of a Muslim to adopt Sharia insurance in Indonesia. The theory of planned behavior is the main factor for Muslim communities to use sharia insurance. Islamic insurance companies need to pay attention to subjective norms, perceived moral control, and public attitudes in promotions to increase the number of new customers.Pertumbuhan asuransi Syariah di Indonesia mengalami pertumbuhan yang signifikan. Pada sisi lain, market share asuransi Syariah di indonesia masih di angka 5%. Sebagai negara dengan penduduk mayoritas muslim, maka penting untuk mengetahui faktor-faktor yang memengaruhi minat seorang muslim untuk mengadopsi asuransi Syariah di Indonesia. Pada penelitian ini, penulis mencoba menganalisis faktor-faktor yang memengaruhi minat seorang muslim untuk menagdopsi asuransi Syariah di Indonesia. Penelitian ini menggunakan pendekatan theory of planned behavior. Hasil penelitian menunjukan bahwasanya variable sikap, subjective norm dan perceived behavioral control memengaruhi secara positif dan signifikan terhadap minat seorang muslim untuk menagdopsi asurani Syariah di Indonesia. Theory of planned behavior merupakan faktor utama masyarakat muslim menggunakan asuransi syariah. Perusahaan asuransi syariah perlu memperhatikan subjective norm, perceived bahvioral control dan sikap masyarakat dalam melakukan promosi untuk menambah jumlah nasabah baru.
Portrait of Capital Accounting Practiced by Students of Sharia Accounting Department From Gorontalo Ethnic
Authors: Thalib Mohamad Anwar
Published: January 2023

This study aims to reveal the values of local wisdom from the way students majoring in Islamic accounting from the Gorontalo tribe practice capital accounting. This study uses an Islamic paradigm with an Islamic ethnomethodology approach. There are five data analysis stages: charity (amal), knowledge (ilmu), faith (iman), information revelation (informasi wahyu), and good deeds (ihsan). The results showed that before receiving the scholarship, the initial capital to finance college was obtained by students from both their parents and their families. The practice of capital accounting is conditional on the value of local wisdom in the form of responsibility. This value is one of the advice the elders often express through lumadu "delo sipati lo malu'o tiloliyo kulu-kulu wala'iyo modudu'o which has a meaning in the form of a feeling of family responsibility".Penelitian ini bertujuan untuk mengungkap nilai-nilai kearifan lokal dari cara mahasiswa jurusan akuntansi syariah yang berasal dari suku Gorontalo mempraktikkan akuntansi modal. Penelitian ini menggunakan paradigma Islam dengan pendekatan etnometodologi Islam. Terdapat lima tahapan analisis data yaitu amal, ilmu, iman, informasi wahyu, dan ihsan. Hasil penelitian menunjukkan bahwa sebelum menerima beasiswa maka modal awal untuk membiayai kuliah diperoleh oleh mahasiswa dari kedua orang tua dan keluarga mereka. Praktik akuntansi modal tersebut syarat dengan nilai kearifan lokal berupa tanggung jawab. Nilai ini merupakan salah satu nasihat yang sering diungkapkan oleh tua-tua melalui lumadu “delo sipati lo malu’o tiloliyo kulu-kulu wala’iyo modudu’o yang memiliki makna berupa perasaan tanggung jawab keluarga”.
Por uma cartografia do (r)existir cotidiano: o viver e as práticas espaciais da comunidade LGBTQIA+ no município de Pelotas
Authors: Alves Pedro , Siqueira Gabriela , Duarte Tiaraju
Published: January 2023

O presente trabalho discute a construção de uma cartografia social da resistência LGBTQIA+ no espaço urbano do município de Pelotas. A análise é fruto da aproximação de duas pesquisas acadêmicas, sendo a primeira um trabalho de conclusão de curso de licenciatura em Geografia  intitulado “As múltiplas territorialidades do medo e violência LGBTQIA+ na cidade de Pelotas: Corpos em processo de exclusão” e o segunda um projeto desenvolvido junto ao grupo de pesquisa “Margens: grupos em processo de exclusão e suas formas de habitar Pelotas/RS” que investiga como os atores pertencentes a comunidade LGBTQIA+ fazem-cidade e exercem seu direito à cidade. Frente a esta apresentação, o objetivo do presente artigo é identificar e cartografar as violências vivenciadas e as estratégias de enfrentamento desenvolvidas por quem é LGBTQIA+ na cidade de Pelotas, possibilitando neste sentido construir recursos didáticos voltados a conscientização desta situação. Em termos metodológicos, para elencar os pontos que seriam marcados em nossa cartografia recorremos, além das pesquisas mencionadas anteriormente, a revisão bibliográfica de trabalhos que abordam questões relacionadas a pessoas LGBTQIA+ no contexto de Pelotas e que tratassem de lugares ou acontecimentos que envolvessem formas de resistência na cidade. O caminho que seguimos para construção da cartografia teve grande influência dos entendimentos, expostos no artigo “Mapas, mapeamentos e a cartografia da realidade”, do geógrafo Seemann (2003). Além disso, para a realização do artigo foram utilizados vídeos, colagens digitais, colagens digitais em vídeos, narrativas, imagens, como formas de representar um cenário urbano que está em constante movimento, construído e reconstruído pela incessante relação entre periferias e centro (AGIER, 2015). Como base conceitual, partimos de um entendimento de resistência formulado por Michel Foucault (1988). Como resultados, podemos visualizar que a cartografia possibilitou identificar locais considerados seguros ou representativos (MAGNANI, 1993) que puderam inclusive se apresentar como formas táticas (CERTEAU, 2008) para fazer-cidade e exercer o direito à cidade (AGIER, 2015) - de pessoas LGBTQIA+. Estes elementos foram explorados por nós como forma de apresentar com diferentes linguagens e possibilidades, por meio da elaboração dos recursos didáticos, uma cidade de Pelotas que é feita de resistência, ainda que em suas dinâmicas existem inúmeras situações de violência. Assim, utilizamos da cartografia como forma de contar, como coloca Jörn Seemann (2003), que a cidade é feita por pessoas LGBTQIA+ através da articulação criativa de ações de lutas e táticas cotidianas para contornar estas violências.

Authors: Gebremeskel Gebeyehu Belay
Published: January 2023

An intelligent transportation system is an efficient and modern digital approach to dealing with massive data, which is pertinent for a future smart city. It is the inherent challenge of data processing in classic vehicular systems. Therefore, I proposed Big Data Analytics (BDA) to optimize the location and safety-based data analytics and performance measures for complete and informative learning processes in various circumstances. The data preprocessing and feature extraction process includes vehicle mobility, multi-source data acquisition, distributed computation, and multi-path data communication in an analytical model to enhance performance and safety. The proposed approach is capable and scalable to manage large-scale sensor data in various contexts. The findings revealed the possible trajectory gained from the online transaction and information flow on digital and safe ITS applications. The experiment showed that leveraging big data technology enhances safe and optimal vehicular system applications. It provides access to shared resources through connected devices and reduces costs using the response time and data structuring to the system stability and to accommodate future modifications in sensor technology.
