Alfabetização e letramento: um olhar para o processo de aprendizagem de crianças com o transtorno do espectro autista (TEA)
Authors: Santos Simone Martins dos , Teixeira Zenaide Dias , Porto Marcelo Duarte
Published: October 2022

Crianças com o Transtorno do Espectro Autista (TEA) podem manifestar dificuldades consideráveis na aquisição da linguagem tanto na modalidade oral, quanto na modalidade escrita. O presente estudo busca entender a complexidade das manifestações anômalas do TEA. Embora a etiologia seja complexa e haja muitas contradições sobre o que realmente é autismo, a manifestação e o diagnóstico clínico se dão por meio de características como a dificuldade para interagir socialmente, a demora na aquisição da linguagem e a dificuldade no domínio da linguagem: ecolalia, comportamento coibitivo e repetitivo. Nesse sentido, compreendendo os processos de alfabetização e letramento como fundamentais na formação do cidadão, investigamos as principais características do TEA, bem como os métodos mais eficazes para alfabetizar e letrar uma criança com este transtorno.
O exame de crenças, estereótipos e atitudes linguísticas na formação do professor: uma via para ensino do pensamento crítico
Authors: Bopp da Silva Taís
Published: October 2022

Este artigo empreende uma reflexão a partir de uma atividade pautada em uma estratégia didática sobre crenças e atitudes linguísticas, desenvolvida com estudantes de Licenciatura em Letras, com intuito fomentar o pensamento crítico sobre a língua. Pensar a língua criticamente constitui competência fundamental para o professor de língua portuguesa que almeja contribuir para a formação de uma sociedade que pense sua língua de modo mais criterioso, com menor consideração a critérios valorativos e a representações linguísticas estereotipadas. Os participantes da atividade que deu origem às reflexões apresentadas neste artigo foram 22 estudantes de Licenciatura em Letras, os quais foram convidados a assistir à comédia dramática “Domésticas, o filme” e a responder um questionário de atitudes linguísticas sobre as personagens retratadas na trama. O inquérito sobre atitudes linguísticas indicou que o grupo pesquisado consegue estabelecer relação entre critérios extralinguísticos e variação linguística; por outro lado, não foi possível afirmar, com base nas respostas, que os participantes rejeitam a ideia de identidade entre o estereótipo linguístico e o grupo retratado por esse estereótipo. Os resultados do teste de atitudes geraram reflexões, que são tema do presente artigo e que foram transformadas em tópicos para uma roda de conversa com os participantes, a qual visou promover uma reflexão crítica acerca de crenças estereotipadas, atitudes e preconceitos linguísticos.

How can linguists support language revitalization efforts in the Brazilian context?
Authors: Amaral Luiz
Published: October 2022

In the last 20 years, language revitalization efforts have grown to the point where we can now talk about a global movement to save the linguistic diversity that exists in different parts of the world. Linguists have long benefited from this multilingualism and in many cases have helped preserve it. In Brazil, we see a growing number of linguists from different subfields trying to find ways in which they can support indigenous communities in their efforts to reverse language loss. As part of a volume on linguistics and education, this paper discusses the potential roles linguists can play in language transmission scenarios where there is a minoritized, endangered language involved. It uses a language planning frame to describe revitalization efforts and to present suggestions to linguists that would like to explore and expand the impact of their work. It is an attempt by a linguist to establish a conversation with other linguists. The perspectives presented here do not represent the point of view of local communities and should be taken for what they are and who they represent.

Authors: Matsumoto Yoshihisa , Nagata Yui , Nakagawa Setsuko , Hashikawa Takuro , Sakai Hideki , Takahashi Shinji , Hashimoto Yosuke , Goto Shin , Sugita Yasuo , Takahashi Kenji
Published: October 2022

BACKGROUND

If complete obliteration of ruptured pediatric arteriovenous malformation (AVM) cannot be achieved, the appropriate follow-up duration and predictors of rebleeding remain unknown.

OBSERVATIONS

Pediatric patients with ruptured AVMs admitted to the authors’ hospital within the past 30 years were evaluated. Rebleeding was confirmed in two patients. The first patient was a 5-year-old boy who experienced right thalamic hemorrhage. AVM was found in the bilateral thalamus and treated with stereotactic radiosurgery (SRS). New aneurysm formation and residual AVM regrowth were confirmed 21 years after the SRS. Eight months later, rebleeding occurred. The second patient was a 5-year-old boy who underwent removal of a left cerebellar hemorrhage and AVM. The residual AVM was treated with SRS. Residual AVM regrowth was detected at 6 years 7 months after SRS. Five months later, new aneurysm formation was confirmed. Two additional days later, rebleeding occurred.

LESSONS

New aneurysm formation and residual AVM regrowth may predict rebleeding and can occur >20 years after the initial rupture and treatment. If AVM obliteration is not achieved, long-term follow-up is needed, even in adulthood, with attention to new aneurysm formation and residual AVM regrowth. Further treatment is recommended if these findings are confirmed.

Penelitian ini bertujuan untuk menemukan dan menganalisa konsep Islam moderat sebagai jalan alternatif dalam membendung paham dan gerakan radikal di Indonesia. Metode penelitian yang digunakan adalah studi kepustakaan yang berusaha mencari berbagai literatur mulai buku, jurnal, dokumen, dan artikel yang sesuai topik kajian. Hasilnya bahwa konsep Islam moderat ialah Islam yang menjunjung tinggi rasa persaudaraan lintas sesama (basyariyah), persamaan, kenegaraan, keharmonisan dan keramahan yang jauh dari sikap fanatik, egois dan penuh kekerasan. Empat prinsip yang dibawa oleh Islam moderat yakni tawasuth, tawazun, tasamuh, dan i’tidal, di mana keempat prinsip tersebut sebagai dasar pengejawantahan dari nilai-nilai Islam rahmatan lil alamin. Strategi dalam mengubah paradigma masyarakat menuju moderat ialah memahami bahwa perbedaan sebagai suatu keniscayaan mutlak dari Allah, keseimbangan dalam beragama menjadi kekuatan sosial untuk tidak mudah menghakimi sesama yang berbeda, kemudian sifat kasih sayang menjadi pengikat untuk memupuk interaksi sosial yang sehat, damai dan jauh dari unsur radikalisme. Sehingga, paham ini bisa dibendung dengan baik.

Ontology-Driven Visual Analytics Platform for Semantic Data Mining and Fuzzy Classification
Authors: Ryabinin Konstantin , Chumakov Roman , Belousov Konstantin , Kolesnik Mariia
Published: October 2022

Visualization is claimed as one of the essential “V’s” of Big Data since it allows presenting the data in a human-friendly way and is, therefore, a stepping-stone for the Big Data mining process. Visual analytics, in turn, ensures knowledge discovery out of the data through cognitive graphics and filtering capabilities. But to be efficient, visualization and analytics tools have to consider other Big Data “V’s” by handling the large data volumes, keeping up with the data growth and changing velocity, and adapting to the variety of the data representation formats. We propose using ontology engineering methods to create a visual analytics platform controlled by an ontological knowledge base that describes supported data types, input formats, data filters, visual objects, and visualization algorithms, as well as available communication protocols and computing nodes, the platform modules can run on. This allows introducing new functions and distributed computation scenarios to the platform on the fly just by extending the underlying domain ontologies without changing the source code of the platform’s core. The analytics flow inside this platform is described by task ontologies enabling semantic data mining process. As a result, seamless integration with different data sources is achieved, including plain files, databases, and even third-party soft- and hardware solvers. We demonstrate the viability of the approach proposed by solving several data mining and fuzzy classification problems, including the assessment of the citizens’ regional identity according to the mental maps they draw and the reconstruction of ontogenesis of extinct synapsid ‘Titanophoneus potens’ Efremov, 1938.

Authors: Si Zhichao , Niu Hongli , Wang Weiqing
Published: October 2022

The main purpose of credit risk assessment is to help financial institutions identify applicants with good credit and eliminate applicants with bad credit, minimizing the risk of capital loss and maximizing returns. Recent years have witnessed excellent performance of machine learning in the credit risk prediction. This paper extends the previous research by applying two boosting algorithms, namely AdaBoost and XGboost, to perform the credit scoring for real data from Lending Club. Compared with two statistical methods and three individual classifiers, the results show that (i) AdaBoost and XGBoost obtain higher forecasting accuracy for credit risk, providing stronger discrimination ability. (ii) AdaBoost has a greater ability to discriminate minority classes (defaulters), which can reduce capital losses for institutions. (iii) XGBoost is able to capture more potential benefits for institutions because it is more accurate in identifying majority classes, i.e., non-defaulters.

COVID-19 detection is an interesting field of study in the medical world and the commonly used method is classification. In determining the best detection model, several classification architectures, such as SVM, KNN, and CNN were utilized. The CNN is a changeable architecture due to having combinations of varying numbers of hidden layers or different activation and optimizer functions. Therefore, this study uses a deep CNN architecture with a combination of Leaky ReLU activation functions and 3 different optimizers, which include Adagrad, Adadelta, and Adamax. The results showed that the combination of the Leaky ReLU activation function and the Adamax optimizer produced good and stable accuracy in the CRX and CT datasets.

Fast Attribute Reduction for Big Datasets Based on Neighborhood Rough Set
Authors: Wang Cheng , Shao Yabin , Peng Xiaoli , Xia Shuyin , Chen Weiqi
Published: October 2022

Neighborhood rough set (NRS) is usually only applicable to small datasets due to the large number of useless and repetitive neighborhood calculations, which severely limits the efficiency of NRS. Many studies improve the efficiency of NRS by narrowing the neighborhood search range down and achieve good performance on small datasets, but they do not perform well on big datasets. To further improve the efficiency on big datasets, we propose a fast attribute reduction method for big datasets based on NRS (FARforBD). In addition, a theorem is also represented to prove the correctness and effectiveness of the proposed method. In FARforBD, we further reduce the neighborhood search range to a neighborhood without any positive region samples. This method greatly reduces many useless neighborhood calculations. The comparison experiments on big datasets show the effectiveness and efficiency of FARforBD.
Neuro-Fuzzy Employee Ranking System in the Public Sector
Authors: Michalopoulos Dimitrios , Karras Aristeidis , Karras Christos , Sioutas Spyros , Giotopoulos Konstantinos C.
Published: October 2022

One of the biggest problems the public sector faces is the proper utilization of human resources. Within a particular combination of practices, dynamic resource allocation management aims to increase employee productivity. The question that arises is how to match the abilities of employees on a measurable scale through their connection with the logic of neuro-fuzzy systems. Productivity and efficiency are two sides of the same coin and are directly related to the deployment of tasks. In this context, the new era of digital transformation along with the automation of processes allows the direct measurement of the workload status at any time. After the deployment of numerous experiments we verify that skill management is linked to performance measurement. Hard skills are selected since there is no direction of how to quantify soft skills and especially when applied to employees of a public body. ANFIS neuro-fuzzy system was selected since it uses the learning algorithm derived from neural network theory along with human criteria. Therefore the proposed system is based on two distinct factors, Skill management and Neuro-Fuzzy Inference System. The model initialization is system-data driven, which enhances the accuracy compared to traditional HR systems and secures a non-subjective procedure on employee management applied to the public sector.
Spatial Feature Evolutionary Relationship Discovery Based on Tree Structure Pattern Mining and Spatial Co-Location Pattern Mining in Spatial Cliques
Authors: Lin Kaishuo , Wang Lizhen , Tran Vanha
Published: October 2022

Feature evolutionary relationship discovery based on tree structure pattern mining and spatial co-location pattern mining in spatial cliques aims to combine spatial co-location pattern mining algorithm and tree structure pattern mining algorithm to find spatial cliques in spatial data and evolutionary relationships of spatial features in these spatial cliques. This allows for a deeper analysis of possible causal relationships between spatial features, predicting the occurrence of other spatial features based on the occurrence of certain spatial features, or summarizing general laws. For a spatial clique, the appearance of one spatial feature may lead to the appearance of another spatial feature, which is called evolutionary relationship. Previous spatial co-location pattern mining algorithms (such as join-based) focus on discovering prevalent co-occur spatial features and prevalent co-location patterns. We further discovered evolutionary relationships between prevalent co-occur spatial features in spatial cliques through tree structure pattern mining algorithm.

Underemployment in a Computable General Equilibrium Model
Authors: Roson Roberto
Published: October 2022

This paper presents a methodology to account, in a computable general equilibrium model, for the presence of underemployment in an economic system. The methodology is based on the estimation of a matrix, mapping different categories of workers to levels of educational attainment. A procedure is proposed, which allows to recalculate the matrix after the realization of a simulation with a CGE model, when employment levels are varied. In this way, a new matrix is made consistent with the simulation results, identifying a new equilibrium in the labor market, which entails a different combination of unemployment and underemployment.

Authors: Mekonin Tadelech
Published: October 2022

When compared to other radiological examinations, computed tomography has a significantly higher radiation exposure and employs ionizing radiation to make an image of a slice or cut of tissue and to learn about the patient's sickness. The current studies' objectives were to determine image quality and radiation dose from the 16-slice Philips CT scanner in order to identify the radiation dose delivered accuracy and the acceptable image quality parameter of CT scanner. The current investigation was carried out using quality assurance CT phantom, Image software, CT dosimeters PMMA phantom coupled with a 100mm pencil chamber. The image quality performance parameters that were tested were image noise, uniformity, CT number accuracy, and resolution. The radiation dose performance parameters that were evaluated were volume computed tomography dose index (CTDIvol), weighed computed tomography dose index (CTDIw), and dose length product (DLP). The results of the present study were measured CTDIvol was 10.01mGy, and the displayed was CTDIvol was 10.2mGy for the head scan technique, 5.8mGy, and 6.1 mGy for the body scan technique respectively. The image quality parameters were 4.4HU, 2.3HU, and 10 8HU for uniformity, contrast to noise ratio, and CT number accuracy for PMMA Quality assurance phantom respectively. The image quality parameter tests were accepted because they were within the tolerance values and the CT radiation dose parameters were not accepted within the international dose reference level. All CT scanners must pass the CT quality control test with respect to image quality and radiation dose for their performance to be improved.

The GDP in the SA was equally reduced by 1.4% which amounted to USD3.69 billion for good on business due to the pandemic. Noticeably, Agriculture and the agro-food industry significantly contribute to the region’s economy. This systematic review critically looked at the implications of the pandemic and its effects on the future of food security. It revealed the need to build productive, sustainable, and inclusive food systems that are resilient enough to revamp the agro-food industry and withstand the future crisis. This is essential for the future of many countries to achieve a systemic transformation and maintain the self-sufficiency level (SSL) planned before the pandemic. This review indicated that a specific disruption to the agro-food supply chain had occurred and consumer’s consumption patterns had been significantly changed which could lead to the post-COVID-19 food crisis. This study presented a framework that could be adopted to ensure the global future of food security in post-COVID-19 with a specific focus on building a resilient agro-food system.
