Application of Transformer-Based Language Models to Detect Hate Speech in Social Media
Authors: Mukherjee Swapnanil , Das Sujit 
Published: December 2021

Detecting and removing hateful speech in various online social media is a challenging task. Researchers tried to solve this problem by using both classical and deep learning methods, which are found to have limitations in terms of the requirement of extensive hand-crafted features, model architecture design, and pretrained embeddings, that are not very proficient in capturing semantic relations between words. Therefore, in this paper, we tackle the problem using Transformer-based pretrained language models which are specially designed to produce contextual embeddings of text sequences. We have evaluated two such models—RoBERTa and XLNet—using four publicly available datasets from different social media platforms and compared them to the existing baselines. Our investigation shows that the Transformer-based models either surpass or match all of the existing baseline scores by significant margins obtained by previously used models such as 1-dimensional convolutional neural network (1D-CNN) and long short-term memory (LSTM). The Transformer-based models proved to be more robust by achieving native performance when trained and tested on two different datasets. Our investigation also revealed that variations in the characteristics of the data produce significantly different results with the same model. From the experimental observations, we are able to establish that Transformer-based language models exhibit superior performance than their conventional counterparts at a fraction of the computation cost and minimal need for complex model engineering.

Ações de prevenção à evasão escolar na Licenciatura em Matemática do IFRN - Campus São Paulo do Potengi
Authors: Lima Neilson Ferreira de , Santos Rênhan Miguel dos 
Published: December 2021

A evasão escolar, de forma simples, é o abandono escolar do aluno, que ocorre em toda e qualquer instituição de ensino. Durante pesquisas realizadas sobre a evasão escolar, foi possível observar a intensa relação desta com a sociedade, visto que a educação de uma sociedade é fortemente prejudicada por este fenômeno, assim como os alunos e as instituições de ensino. Por ser um fenômeno complexo, é difícil de mapear todas as possíveis variáveis ou fatores que estão envolvidos nesse evento. Sabe-se que a evasão nos cursos é real e praticamente inevitável. Através de pesquisas com abordagem exploratória, descritiva, explicativa, de campo e quali-quantitativa na Licenciatura em Matemática do Instituto Federal do Rio Grande do Norte - IFRN Campus São Paulo do Potengi, observou-se que os maiores fatores da evasão escolar estão ligados às questões socioeconômicas, acadêmicas e culturais dos discentes. Falta de transporte, lacunas no conhecimento matemático e conciliar estudo e trabalho também apareceram como fatores de risco à evasão. Diante disso, foram realizadas ações de combate à evasão e de permanência e êxito, tais como rodas de conversa com a turma, com o fim de nos aproximarmos para conhecê-los melhor e ajudá-los nas dificuldades. Através dos diálogos foi possível evitar que alunos se evadissem e permanecessem no curso.

Authors: Koftun Camila Maria , Basniak Maria Ivete 
Published: December 2021

Este trabalho investigou implicações do PIBID – Programa Institucional de Bolsas de Iniciação à Docência para o desenvolvimento do conhecimento profissional dos professores supervisores, a partir das componentes da scholarship da docência. Estas componentes são a autocompreensão profissional e a teoria educacional subjetiva. Trata-se de uma pesquisa qualitativa de cunho investigativo e interpretativo, em que foi utilizado o grupo focal, que reuniu alguns dos professores supervisores que atuaram no subprojeto do PIBID de Matemática da UNESPAR – Campus de União da Vitória entre 2012 e 2017, para discutirem sobre suas experiências no PIBID. Posteriormente, a análise de dados revelou a influência de ações desenvolvidas com o PIBID no conhecimento profissional desses professores, principalmente no que diz respeito às reflexões e discussões coletivas decorrentes da participação no Programa, agregando novas ideias e elementos para suas práticas, assim como o desenvolvimento de aspectos da scholarship da docência. A atuação dos professores supervisores no PIBID deve ser reconhecida como uma política de formação continuada de professores, porque possibilita a articulação teoria-prática e, dessa forma, apresenta potencial maior do que os documentos que regulam o programa revelam.

Published: December 2021

Este artigo é o relato de uma pesquisa qualitativa, que foi desenvolvida com o objetivo principal de elaborar, desenvolver e analisar uma sequência didática, envolvendo o conteúdo de função quadrática. Para isso, foi adaptada e utilizada uma atividade descrita no capítulo referente a esse conteúdo no Livro Aberto de Matemática sobre a altura do Arco da Apoteose. A sequência foi aplicada aos alunos do 1º ano do Ensino Médio de uma escola particular da região central do Rio Grande do Sul, de maneira remota, devido à pandemia do Covid-19, e a metodologia de Resolução de Problemas foi adaptada para tal momento. Analisando as respostas dos alunos, podemos inferir que os conceitos sobre a função quadrática ainda não foram bem compreendidos. Os alunos apresentam dificuldades para transitar entre os registros algébricos e gráficos da função quadrática bem como compreender o significado dos parâmetros da função. Com isso, percebe-se a necessidade de se trabalhar esses conceitos em diferentes problemas e a transição desses registros, para que os alunos consigam aperfeiçoar o entendimento desses conceitos.

Published: December 2021

Este artigo, recorte de um estudo de doutorado, discute uma proposta metodológica fruto da pesquisa de abordagem experimental desenvolvida nos pressupostos da Didática da Matemática como uma Engenharia Didática e objetiva descrever algumas das contribuições de uma Sequência Didática (SD) elaborada para o ensino de números naturais. Analisamos as contribuições, condições e restrições para a sua implementação, visando o desenvolvimento do pensamento algébrico. Esta compreendeu oito momentos didáticos e a experimentação se deu com 111 alunos de três turmas do 6º Ano do Ensino Fundamental de uma escola pública estadual. Os problemas aplicados nas três sessões de experimentação foram elaborados a partir da análise preliminar do livro didático, das orientações curriculares e da revisão de literatura, em linguagem natural, numérica e icônica com recursos ostensivos, como o registro escrito, tabelas, bolinhas, figuras, que pudessem evocar elementos não ostensivos, como o pensamento algébrico. A Engenharia Didática sistematizou o estudo e as atividades da SD, direcionou nossas análises e possibilitou uma interessante interlocução entre os objetivos traçados para a pesquisa a partir do cruzamento das análises, e do que recolhemos de dados nas experimentações. Resultados apontaram que o pensar algebricamente se manifesta principalmente na capacidade de estabelecer relações entre os dados de um problema, significando-os. Assim, a SD, a Engenharia Didática e os arcabouços teóricos da Didática da Matemática se mostraram frutíferos, a partir dos resultados obtidos. As atividades sistematizadas e sua condução didática contribuíram para a promoção do conhecimento e o enriquecimento da educação algébrica e assim da aprendizagem matemática, além de mostrar caminhos a outras pesquisas.

infrastructure of life
Authors: Lidin Konstantin 
Published: December 2021

The infrastructure of the city accompanies a person at all stages of their biography, including death as an integral attribute of life. This section includes three articles, the authors of which appear in our journal for the first time. The articles discuss strong trends that usually escape the attention of architectural theorists. There is a return of communal and other forms of housing where people unrelated to each other live under the same roof. Is it a global trend or a forced measure against economic hardships? A rethink of the rental house, a rapid shift in the balance from home ownership to rental housing – how will this affect the architecture of cities?
In the general trend of changing attitudes to death and the process of dying, the subject of hospice architecture until recently was taboo, but now strongly attracts architects’ attention. The articles of our new authors are more of a question-posing and problematic nature, which is exactly in the style of our journal.
Impact of the COVID-19 pandemic related to lockdown measures on tropospheric NO2 columns over Île-de-France

Published: December 2021

Abstract. The evolution of NO2, considered as a proxy for air
pollution, was analyzed to evaluate the impact of the first lockdown (17 March–10 May 2020) over the Île-de-France region (Paris and surroundings). Tropospheric NO2 columns measured by two UV-Visible Système d'Analyse par Observation Zénithale (SAOZ) spectrometers were analyzed to compare the evolution of NO2 between
urban and suburban sites during the lockdown. The urban site is the
observation platform QualAir (48∘50′ N / 2∘21′ E) at the Sorbonne University Pierre and Marie Curie Campus in the center of Paris. The suburban site is located at Guyancourt (48∘46′N / 2∘03′E), Versailles Saint-Quentin-en-Yvelines University, 24 km southwest of Paris. Tropospheric NO2 columns above Paris and Guyancourt have shown similar
values during the whole lockdown period from March to May 2020. A decade of data sets were filtered to consider air masses at both sites with similar meteorological conditions. The median NO2 columns and the surface measurements of Airparif (Air Quality Observatory in Île de France)
during the lockdown period in 2020 were compared to the extrapolated values
estimated from a linear trend analysis for the 2011–2019 period at each
station. Negative NO2 trends of −1.5 Pmolec. cm−2 yr−1
(∼ −6.3 % yr−1) are observed from the columns, and trends of −2.2 µg m−3 yr−1 (∼ −3.6 % yr−1) are observed from the surface concentration. The negative anomaly in tropospheric columns in 2020 attributed to the lockdown (and related emission reductions) was found to be 56 % at Paris and 46 % at Guyancourt, respectively. A similar anomaly was found in the data of surface concentrations, amounting to 53 % and 28 % at the urban and suburban sites, accordingly.
PARAFOG v2.0: a near-real-time decision tool to support nowcasting fog formation events at local scales
Authors: Ribaud Jean-François , Haeffelin Martial , Dupont Jean-Charles , Drouin Marc-Antoine , Toledo Felipe , Kotthaus Simone 
Published: December 2021

Abstract. An improved version of the near-real-time decision tool PARAFOG (PFG2) is
presented to retrieve pre-fog alert levels and to discriminate between
radiation (RAD) and stratus lowering (STL) fog situations. PFG2 has two
distinct modules to monitor the physical processes involved in RAD and STL
fog formation and is evaluated at European sites. The modules are based on
innovative fuzzy logic algorithms to retrieve fog alert levels (low,
moderate, high) specific to RAD/STL conditions, minutes to hours prior to
fog onset. The PFG2-RAD module assesses also the thickness of the fog. Both
the PFG2-RAD and PFG2-STL modules rely on the combination of visibility
observations and automatic lidar and ceilometer (ALC) measurements. The
overall performance of the PFG2-RAD and PFG2-STL modules is evaluated based on
9 years of measurements at the SIRTA (Instrumented Site for Atmospheric Remote Sensing Research) observatory near Paris and up to two
fog seasons at the Paris-Roissy, Vienna, Munich, and Zurich airports. At all
sites, pre-fog alert levels retrieved by PFG2 are found to be consistent
with the local weather analysis. The advanced PFG2 algorithm performs with a
hit rate of about 100 % for both considered fog types and presents a
false alarm ratio on the order of 10 % (30 %) for RAD (STL) fog
situations. Finally, the first high alerts that result in a subsequent fog
event are found to occur for periods of time ranging from −120 min to
fog onset, with the first high alerts occurring earlier for RAD than STL cases.
Performance analysis of 300 GHz backhaul links using historic weather data
Authors: Jung Bo Kum , Kürner Thomas 
Published: December 2021

Abstract. According to the recently published IEEE standard 802.15.3d (2017), THz links operating at 300 GHz are viable to achieve more than 100 Gbit s−1 of data rate. This feature can support a transition of the future backhaul connectivity from the underground fibre connection to the wireless, where fibre links are not available or too costly to install. The EU-Japan Horizon 2020 project “ThoR” is working towards the demonstration of such links. A detailed investigation on the influence of weather conditions will help to derive planning guidelines of 300 GHz backhaul links for forthcoming applications. This paper focuses on the dependency of the THz link on the general weather by using ray-tracing simulation. Simulation is conducted combining ITU-R propagation models for atmospheric attenuation (water vapour and oxygen content of air, droplets of rains, liquid content of clouds or fog), a wind-depending swaying model for the antenna poles, and historical measured climate data for the deployment scenarios considered in the ThoR project. As a result, this research will show the feasibility of THz link in outdoor applications under general weather conditions, defines weather-dependent outage probabilities, and allows us to derive planning guidelines of THz links at a frequency of 300 GHz.

Abstract. Model simulations and remote sensing observations show that ocean dynamics at fine scales (1–100 km in space, day–weeks in time) strongly influence the distribution of phytoplankton.
However, only a few in situ-based studies at fine scales have been performed, and most of them concern western boundary currents which may not be representative of less energetic regions.
The PROTEVSMED-SWOT cruise took place in the moderately energetic waters of the western Mediterranean Sea (WMS), in the region south of the Balearic Islands.
Taking advantage of near-real-time satellite information, we defined a sampling strategy in order to cross a frontal zone separating different water masses.
Multi-parametric in situ sensors mounted on the research vessel, on a towed vehicle and on an ocean glider were used to sample physical and biogeochemical variables at a high spatial resolution.
Particular attention was given to adapting the sampling route in order to estimate the vertical velocities in the frontal area also.
This strategy was successful in sampling quasi-synoptically an oceanic area characterized by the presence of a narrow front with an associated vertical circulation.
A multiparametric statistical analysis of the collected data identifies two water masses characterized by different abundances of several phytoplankton cytometric functional groups, as well as different concentrations of chlorophyll a and O2.
Here, we focus on moderately energetic fronts induced by fine-scale circulation.
Moreover, we explore physical–biological coupling in an oligotrophic region.
Our results show that the fronts induced by the fine-scale circulation, even if weaker than the fronts occurring in energetic and nutrient-rich boundary current systems, maintain nevertheless a strong structuring effect on the phytoplankton community by segregating different groups at the surface.
Since oligotrophic and moderately energetic regions are representative of a very large part of the world ocean, our results may have global significance when extrapolated.
Seasonal evolution of basal environment conditions of Russell sector, West Greenland, inverted from satellite observation of surface flow

Published: December 2021

Abstract. Due to increasing surface melting on the Greenland ice sheet, better constraints on seasonally evolving basal water pressure and sliding speed are required by models. Here we assess the potential of using inverse methods on a dense time series of surface speeds to recover the seasonal evolution of the basal conditions in a well-documented region in southwest Greenland. Using data compiled from multiple satellite missions, we document seasonally evolving surface velocities with a temporal resolution of 2 weeks between 2015 and 2019. We then apply the inverse control method using the ice flow model Elmer/Ice to infer the basal sliding and friction corresponding to each of the 24 surface velocity data sets. Near the margin where the uncertainty in the velocity and bed topography are small, we obtain clear seasonal variations that can be mostly interpreted in terms of an effective-pressure-based hard-bed friction law. We find for valley bottoms or “troughs” in the bed topography that the changes in modelled basal conditions directly respond to local modelled water pressure variations, while the link is more complex for subglacial “ridges” which are often non-locally forced. At the catchment scale, in-phase variations in the water pressure, surface velocities, and surface runoff variations are found. Our results show that time series inversions of observed surface velocities can be used to understand the evolution of basal conditions over different timescales and could therefore serve as an intermediate validation for subglacial hydrology models to achieve better coupling with ice flow models.
