The premium of uncertain risk based on standard deviation principle
Authors: Zhang Yunqi , Sheng Yuhong
Published: March 2023

Risk measurement and insurance pricing have always been issues of concern in actuarial science. Under the framework of uncertainty theory, this paper puts forward a new premium principle: uncertain standard deviation premium principle, proposes some of its properties about risk and compares the premiums of different risks. Based on the utility function of risk aversion, the additional premium coefficient is derived and two specific numerical examples are used to calculate the maximum premium. Furthermore, the unknown parameters of the policy with deductible are estimated by uncertain moment estimation and uncertain maximum likelihood estimation.
A quantum-like text representation based on syntax tree for fuzzy semantic analysis
Authors: Yu Yan , Qiu Dong , Yan Ruiteng
Published: March 2023

To mine more semantic information between words, it is important to utilize the different semantic correlations between words. Focusing on the different degrees of modifying relations between words, this article provides a quantum-like text representation based on syntax tree for fuzzy semantic analysis. Firstly, a quantum-like text representation based on density matrix of individual words is generalized to represent the relationship of modification between words. Secondly, a fuzzy semantic membership function is constructed to discuss the different degrees of modifying relationships between words based on syntax tree. Thirdly, the tensor dot product is defined as the sentence semantic similarity by combining the operation rules of the tensor to effectively exploit the semantic information of all elements in the quantum-like sentence representation. Finally, extensive experiments on STS’12, STS’14, STS’15, STS’16 and SICK show that the provided model outperforms the baselines, especially for the data set containing multiple long-sentence pairs, which confirms there are fuzzy semantic associations between words.
Majority voting based on different feature ranking techniques from gene expression
Authors: Bolourchi Pouya , Ghasemzadeh Aman
Published: March 2023

In bioinformatics studies, many modeling tasks are characterized by high dimensionality, leading to the widespread use of feature selection techniques to reduce dimensionality. There are a multitude of feature selection techniques that have been proposed in the literature, each relying on a single measurement method to select candidate features. This has an impact on the classification performance. To address this issue, we propose a majority voting method that uses five different feature ranking techniques: entropy score, Pearson’s correlation coefficient, Spearman correlation coefficient, Kendall correlation coefficient, and t-test. By using a majority voting approach, only the features that appear in all five ranking methods are selected. This selection process has three key advantages over traditional techniques. Firstly, it is independent of any particular feature ranking method. Secondly, the feature space dimension is significantly reduced compared to other ranking methods. Finally, the performance is improved as the most discriminatory and informative features are selected via the majority voting process. The performance of the proposed method was evaluated using an SVM, and the results were assessed using accuracy, sensitivity, specificity, and AUC on various biomedical datasets. The results demonstrate the superior effectiveness of the proposed method compared to state-of-the-art methods in the literature.

Background: Spinal muscular atrophy (SMA) is a hereditary motor neuron disorder, characterized by the degeneration of motor neurons and progressive muscle weakness. There is a large variability of disease severity, reflected by the classification of SMA types 1–4. Objective: The aim of this cross-sectional study was to determine the nature of swallowing problems and underlying mechanisms in patients with SMA types 2 and 3, and the relationship between swallowing and mastication problems. Methods: We enrolled patients (aged 13–67 years) with self-reported swallowing and/or mastication problems. We used a questionnaire, the functional oral intake scale, clinical tests (dysphagia limit, and timed test swallowing, the test of mastication and swallowing solids), a videofluoroscopic swallowing study (VFSS), and muscle ultrasound of the bulbar muscles (i.e. digastric, geniohyoid and tongue muscles). Results: Non-ambulant patients (n = 24) had a reduced dysphagia limit (median 13 ml (3–45), and a swallowing rate at the limit of normal (median 10 ml/sec (range 4–25 ml). VFSS revealed piecemeal deglutition and pharyngeal residue. We found pharyngo-oral regurgitation in fourteen patients (58%), i.e. they transported the residue from the hypopharynx back into the oral cavity and re-swallowed it. Six patients (25%) demonstrated impaired swallowing safety (i.e. penetration aspiration scale > 3). Muscle ultrasound revealed an abnormal muscle structure of the submental and tongue muscles. Ambulant patients (n = 3), had a normal dysphagia limit and swallowing rate, but VFSS showed pharyngeal residue, and muscle ultrasound demonstrated an abnormal echogenicity of the tongue. Swallowing problems were associated with mastication problems (p = 0.001).
Short-term forecast of U.S. COVID mortality using excess deaths and vector autoregression
Authors: Britt Tom , Nusbaum Jack , Savinkina Alexandra , Shemyakin Arkady
Published: March 2023

We analyze overall mortality in the U.S. as a whole and several states in particular in order to make conclusions regarding timing and strength of COVID pandemic effect from an actuarial risk analysis perspective. No effort is made to analyze biological or medical characteristics of the pandemic. We use open data provided by CDC, U.S. state governments and Johns Hopkins University. In the first part of the paper, we suggest time series analysis (ARIMA) for weekly excess U.S. mortality in 2020 as compared to several previous years’ experience in order to build a statistical model and provide short-term forecast based exclusively on historical mortality data. In the second half of the paper, we also analyze weekly COVID cases, hospitalizations and deaths in 2020 and 2021. Two midwestern states, Minnesota and Wisconsin, along with geographically diverse Colorado and Georgia, are used to illustrate global and local patterns in the COVID pandemic data. We suggest vector autoregression (VAR) as a method of simultaneous explanatory and predictive analysis of several variables. VAR is a popular tool in econometrics and financial analysis, but it is less common in problems of risk management related to mortality analysis in epidemiology and actuarial practice. Efficiency of short-term forecast is illustrated by observing the effect of vaccination on COVID development in the state of Minnesota in 2021.
The 2022 Czech EU Council Presidency: Performance in the Fields of Security, Energy and Rule of Law
Authors: Kovář Jan , Weiss Tomáš
Published: March 2023

By the end of December 2002, the Czech EU Council presidency came to an end. Czechia was holding the rotating Council presidency for the second time and like in 2009 its presidency trio was rounded out by the preceding French presidency and the following Swedish one. The key difference between the two Czech presidencies was the changed institutional context. While the 2009 presidency took place on the verge of the entrance into force of the Lisbon Treaty, the Treaty nevertheless only came into effect in December 2009, a couple months after the Czechs passed the presidency baton to the Swedes. The 2022 Czech presidency was thus the first that the country held under the Lisbon rules. These rules curtailed the role of the rotating presidency in terms of presiding over the European Council as well as the Foreign Affairs Council. Most importantly, the practicalities of the Czech presidency were affected by the suddenly changed international context following the Russian aggression against Ukraine. The Czech presidency as well as the presidency trio had to revise their priorities and the entire EU was primarily focused on the war in Ukraine and its consequences. This special forum containing seven articles provides an early analysis that engages the existing scholarly literature on the performance of Czechia at the helm of the EU.

Convolutional neural networks (CNNs) play an important role in many computer vision applications such as object classification and recognition. To achieve high recognition rate, these neural networks are usually implemented on high-performance computing platforms with high processing speed and large memory. This is a big obstacle for deploying these models on devices with limited hardware resources such as embedded computers. For convolution layers, it requires a lot of multiply-accumulation operations to extract useful features from input images. Furthermore, multiplication of floating-point numbers has long latency and demands a big hardware overhead. In this paper, we analyze and identify the causes that limit the performance of CNNs. Then a method for implementing convolutional networks on hardware with limited resources is presented. Performance evaluation in terms of power, execution time as well as recognition rate is presented in detail. Experimental results on both the FPGA hardware platform and the ARM Cortex-A embedded processor indicate that CNNs using the XNOR-popcount approach can be optimized to achieve a 1000-fold increase in computational performance and approximately a 24-fold reduction in power consumption compared to the tranditional implementation of CNNs on common embedded computer systems.

Gac oil was encapsulated in the hydrogel bead using alginate as carrying material by dripping method. Different parameters of all three stages of the encapsulation process were investigated: alginate concentration (emulsification stage), nozzle height, extruded pressure (bead formation stage) and calcium flow rate (bead stabilisation stage). Gac oil emulsion was characterised through the droplet’s size and emulsion stability. Bead’s morphology including size and shape was evaluated by image analysis using ImageJ software. Encapsulation efficiency was evaluated through encapsulated Gac oil and beta-carotene stability during storage at room temperature during 8 weeks. The beta-carotene content was determined through spectrometric absorbance in n-hexane at 452 nm. Results show that alginate is suitable to use as carrying material for Gac oil encapsulation with a moderate encapsulation efficiency of 62.5 ± 0.8 %. Gac oil emulsion had a droplet’s size in range 1-2 m and showed a good stability at low alginate concentration. The bead’s morphology was highly affected by the height of nozzle and the extruded pressure while the flow rate of gelling solution expressed no influence of the bead’s morphology. The most spherical bead and the biggest bead’s diameter were obtained with the lowest distance at 150 mm and the lowest pressure at 2 MPa. A smaller size but more irregular shape can be obtained with the higher distances and higher pressures. A progressive decrease in beta-carotene content during storage was observed for both bead’s surficial and total level. The degradation of beta-carotene in Gac oil bead fitted the first-order reaction with degradation rate constant k of 0.0020 day-1 and a hafl-life t1/2 equal to 347 days which show a good stabiltity of Gac oil in alginate bead.

In the field of agriculture, the conservation of the agricultural products plays a vital role. The challenge in this topic is to manage a large scale of storehouse by manual works. Therefore, an implementation of IoT-based controller for monitoring in preserving fruits such as dragon fruit or jackfruit as a remotely monitored solution. First of all, the analysis of hardware platform and software programming is completed in this work. Several peripheral devices must be deployed in order to send or receive data online. Some sensing boards are also suggested to measure the physical variables such as temperature or humidity. In addition, the overall system is supervised in any time to ensure the whole process. After the procedure of data collection, there is optional filtering method to choose the correct information owing to the large scale of measuring values. Later, a GUI (Graphical User Interface) program is produced to support the system management. Any change in this system would be displayed as soon as possible. This software might be programmed by Visual Studio 2019 using C/C++ language. An operator could open this software in the host computer or mobile device with internet connection. MQTT (Message Queuing Telemetry Transport) protocol is suggested to maintain the data exchange between slaves and host. Thanks to this function, the flow of data could be transmitted fluently and continuously. To verify the effectiveness and feasibility of our approach, several tests are carried out. The system is validated when the environmental conditions are normally obtained. Although there needs several implementations to enhance the system performance, the use of the proposed design in practical system provides the robustness, effectiveness and feasibility for an industrial solution.

Published: March 2023

Social responsibility is achieving goals for the community, one of which is purchase intention, which is influenced by customer company identification, trust, general attitude, and purchase intention based on the sustainability theory on marketing, especially when companies maintain their status and standing in the business world. This study aims to determine the effect of the relationship between hypotheses on bottled mineral water products from the research gap. The object research focused on bottled mineral water product companies with the subject of bottled mineral water consumers from all walks of life. This research used Structural Equation Modeling (SEM) with 232 respondents who participated in responding to the research questionnaires. The results of the study indicate the rejection of one hypothesis that connects the influence between trust and purchase intention on bottled mineral water products due to privacy issues among consumers.

Published: March 2023

Thin films produced by deposition of metal oxides on different surfaces show semi-conductor properties that are sensitive to the surrounding atmosphere components. With their optical, electrical, and structural properties, CdO metal oxides are used in a variety of fields ranging from optoelectronic materials to gas sensors. CdO thin films can be produced by different methods such as spray pyrolysis, SILAR, sol-gel spin coating and dip coating technique. The sol-gel dip coating technique, which is simple, accessible, adjustable, and repeatable based on desired parameters, is widely used in the production of CdO thin films. In this study, CdO metal oxide thin films were coated on polyamide, acrylic and cotton yarns by sol-gel dipping method in three different molarities of 0.1 M, 0.3 M and 0.5 M starting solutions. Structural properties of CdO thin film coated yarn samples were investigated using SEM and EDX analyzes were performed. The sensor tests of the yarn samples for LPG gas were carried out in the specially designed gas sensor measurement system and in the gas chamber. The 0.5 M CdO thin film coated cotton yarn samples showed better semiconductor properties and gas response than the other samples.

Published: March 2023

İletişim araştırmalarında medyanın ekonomik yönüne duyulan ilgi, toplumsal yönüne duyulan ilgiye kıyasla her zaman biraz geride kalmıştır. Ancak teknoloji şirketleri ile medya şirketlerinin sınırlarının birbirine karışması, medya tüketicilerinin tercihlerinde yaşanan radikal değişimler, yıllardan beri uygulanan iş modellerinin bir süredir geçerliliğini yitirmiş olması gibi büyük değişimler medyaya ekonomik gözle bakılmasını adeta zorunlu kılmaktadır. Medya ekonomisi ve işletmeciliği; ülkemizde ‘basın ekonomisi ve işletmeciliği’, ‘medya ekonomisi ve işletmeciliği’, ‘medya ekonomisi’, ‘medya işletmeciliği’ adlarıyla 21 üniversitede gazetecilik bölümleri altında bir anabilim dalı olarak yer almaktadır. Ancak lisansüstü düzeyinde eğitim sadece Marmara Üniversitesi ve Ege Üniversitesi’nde verilmektedir. Bu çalışmanın amacı, söz konusu alanda üretilen lisansüstü tezleri tespit ederek bibliyometrik analize tabi tutmak, böylece bu alanda gelecekte yapılacak araştırmalara ışık tutmaktır. Çalışmada, YÖK Ulusal Tez Merkezi’nde detaylı tarama yapılarak 1995-2022 yılları arasında yayınlanan 149 teze ulaşılmıştır. Bu tezlerden 148 tanesinin Marmara Üniversitesi’nde, 1 tanesinin Ege Üniversitesi’nde üretildiği; üretilen tezlerden 31 tanesinin doktora, 118 tanesinin yüksek lisans seviyesinde olduğu; doktora tezlerinin ortalama 286,5 sayfa, yüksek lisans tezlerinin ortalama 161,3 sayfa olarak hazırlandığı tespit edilmiştir.

Did a nocebo effect contribute to the rise in special education enrollment following the Flint, Michigan water crisis?
Authors: Roy Siddhartha , Petrie Keith J. , Gamble Greg , Edwards Marc A.
Published: March 2023

Background

Exposure to waterborne lead during the Flint Water Crisis during April 2014-October 2015 is believed to have caused increased special education enrollment in Flint children.

Method

This retrospective population-based cohort study utilized de-identified data for children under six years of age who had their blood lead tested during 2011 to 2019, and special education outcomes data for children enrolled in public schools for corresponding academic years (2011-12 to 2019-20) in Flint, Detroit (control city) and the State of Michigan. Trends in the following crisis-related covariates were also evaluated: waterborne contaminants, poverty, nutrition, city governance, school district policies, negative community expectations, media coverage and social media interactions.

Results

Between 2011 and 2019, including the 2014-15 crisis period, the incidence of elevated blood lead in Flint children (≥ 5µg/dL) was always at least 47% lower than in the control city of Detroit (p < .0001) and was also never significantly higher than that for all children tested in Michigan (p = 0.33). Nonetheless, special education enrollment in Flint spiked relative to Detroit and Michigan (p < .0001). There is actually an inverse relationship between childhood blood lead and special education enrollment in Flint.

Conclusion

This study failed to confirm any positive association between actual childhood blood lead levels and special education enrollment in Flint. Negative psychological effects associated with media predictions of brain damage could have created a self-fulfilling prophecy via a nocebo effect. The findings demonstrate a need for improved media coverage of complex events like the Flint Water Crisis.

Published: March 2023

Academic Frequently Asked Questions (FAQ) service is a service designed to answer academic questions that are often asked by students. A survey conducted on April 12, 2022, to 33 students of the Ahmad Dahlan University Informatics study program showed that 39.4% of students rarely open the FAQ menu on the portal application. Students more often ask questions to administrators and lecturers, but 30.3% of students receive answers that last more than 10 minutes. Chatbot is an artificial intelligence system used to interact with users in real-time to provide information. The use of dialog flow in the system helps manage information and can provide an answer quickly and precisely to users. This research uses the waterfall method, which is a simple classic model with a linear flow system. The User Experience Questionnaire (UEQ) survey results get a score of 1,536 for attractiveness, 1,714 for clarity, 1,375 for efficiency, 1,357 for fixity, 1,536 for stimulation, and 0.964 for novelty. Based on these results, it shows that the application level is above average on the UEQ scale.
Narrative Economics: An Emerging New Research Approach
Authors: Baszczak Łukasz
Published: March 2023

Artykuł prezentuje obszerny i krytyczny przegląd badań ekonomicznych, które
można zakwalifikować do kształtującego się nurtu ekonomii narracji. Jego głównym
celem jest odkrywanie ekonomicznego znaczenia narracji, które są rozumiane
generalnie jako opowieści rozpowszechnione w społeczeństwie. W pracy zaprezentowano
trzy główne podgrupy badań nad narracjami w ekonomii. Pierwszą stanowią
badania ekonomiczne nad zróżnicowaniem kulturowym społeczeństw, które
może wynikać z różnic między narracjami w poszczególnych kulturach. Druga
grupa to analizy i prognozy fluktuacji zmiennych makroekonomicznych dokonywane
przy wykorzystaniu metody automatycznej analizy różnych charakterystyk
(np. poruszanych tematów czy prezentowanych odczuć) dużych korpusów tekstów,
często prasowych. Trzecią kategorię tworzą badania oparte na eksperymentach,
które ukazują rolę narracji w kształtowaniu preferencji, zachowania, sposobu
myślenia i podejmowaniu decyzji przez jednostkę (w szczególności poprzez czynienie
sensownymi surowych danych ze świata zewnętrznego). Pogłębiony przegląd
literatury pozwolił na wyciągnięcie wniosków: narracje mają duży potencjał, jeśli
chodzi o dziedzinę ekonomii, ale w ramach tego nurtu pojawiają się też problemy,
takie jak rozmycie definicji narracji, niejasność kanału przyczynowego oddziaływania
narracji i imperializm ekonomii. Wynikają one m.in. ze zbyt powierzchownego
i czysto ilościowego traktowania przez ekonomistów tekstów jako nośników
narracji i z niedostatku badań skupiających się na szczegółowej analizie funkcjonowania
konkretnych narracji. W tym przypadku ważne może być przeniesienie
idei z innych dyscyplin, takich jak interdyscyplinarny nurt analizy dyskursu.
Incidencia del uso de sustancias ilegales y alcohol para el cometimiento de delitos en la ciudad de Riobamba, en el año 2021
Authors: Ponce González Renata Doménica , Moncayo Molina Wilson Edwin
Published: March 2023

Introducción: tomando en cuenta que el índice de criminalidad y delincuencia se ha incrementado a nivel nacional en los últimos años y que en muchas modalidades de ataque los delincuentes usan sustancias estupefacientes y psicotrópicos para facilitar el crimen. Objetivos: se investigó la incidencia del uso de sustancias ilegales y alcohol para el cometimiento de delitos en la ciudad de Riobamba con datos del año 2021, Metodología: en primera instancia fue necesario revisar información procedente del laboratorio del Servicio de Medicina Legal de Chimborazo y de un laboratorio de toxicología privado con el fin de obtener datos reales procedentes de víctimas de la delincuencia cuyos casos han sido denunciados en las instancias pertinentes. Posteriormente se procesó la información para determinar cuáles eran las principales sustancias utilizadas en los móviles, y qué delitos eran los más frecuentes. Resultados: se analizó la sintomatología de las víctimas al igual que y se clasificó para las sustancias utilizadas en delitos como psicotrópicas o estupefacientes y finalmente se determinó la relación existente entre letalidad de víctimas y sustancias utilizadas en el cometimiento de delitos mediante la aplicación de análisis de datos y estadística. Conclusiones: se concluyó que la marihuana, cocaína, benzodiacepinas, barbitúricos y alcaloides son las sustancias ilegales más utilizadas por los delincuentes y que el robo es el principal delito por el cual las víctimas son sometidas, la gran mayoría de víctimas presentan episodios de confusión, desorientación, perdida de voluntad y equilibrio, son síntomas causados por las sustancias ilegales y aprovechados por la delincuencia. El alcohol etílico presente en bebidas alcohólicas juega un papel preponderante en el accionar delincuencial ya que es combinado frecuentemente con las sustancias ilegales aprovechando la capacidad de enmascarar olores y sabores de las drogas. Si bien en los casos analizados ninguna de las victimas ha perdido su vida debido a sobredosis o toxicidad de las sustancias utilizadas las cantidades suministradas facilitan la manipulación de la voluntad de las víctimas. Se recomienda utilizar esta investigación como una herramienta para coadyubar en la protección ciudadana y la prevención de delitos ya que los datos determinados obedecen a casos reales suscitados en la ciudad de Riobamba. Área de estudio general: ciencias forenses. Área de estudio específica: toxicología.

Published: March 2023

Purpose. The Bou Azzer Mine encounters difficulties during cobalt mining. In order to select the optimal mining sequence with the least geotechnical stability problems, one possible variant is the cut and backfill mining method used in the Bou Azzer East area at a depth of 540 m. Methods. This paper presents a methodology for selecting a sequence of the cut and backfill mining method using 2D geotechnical numerical modeling, taking into account the morphological characteristics, geomechanical properties of the ore and the surrounding rocks. Findings. The sequences of mining with rock backfill and rock-cemented backfill show that the high principal stress (Sigma 1) is in the range of 10-153 MPa, and the safety factors are in the range of 0.63-1.89. Therefore, mining sequences with cemented backfill and under cemented backfill have a principal stress (Sigma 1) in the range of 10-112 MPa and acceptable safety factors. Originality. In this study, the bottom-up mining sequence with a cemented backfill is proposed for the case of low-quality serpentine footwall. This mining sequence aims to achieve good cobalt mine production and provides a safe environment for miners. Practical implications. In the mining industry, the choice of mining method using 2D or 3D geotechnical numerical mo-deling is important to ensure the safest and most operational mining sequence in the mine lifetime.

Interventions for Enhancing Indigenous Undergraduates' Programming Learning: A Systematic Review
Authors: Rajendra Kumar Janaanie , Mohamad Fitri Suraya
Published: March 2023

This study reviews the challenges faced by indigenous undergraduates in learning programming and identifies interventions to address them. A systematic review of 37 studies published between 2000 and 2022 found that Indigenous undergraduates face barriers to learning programming related to their indigeneity, motivation, mathematics anxiety, cognitive load, pedagogy, prior knowledge, critical thinking, and programming language anxiety. Interventions such as ethnoprogramming, culturally responsive pedagogy, ethnomathematics, and gamification have been proposed to overcome these challenges. Our review and analysis suggest that culturally responsive pedagogy and gamification show promise in improving indigenous undergraduates' programming learning outcomes. This study highlights the importance of designing effective interventions to support Indigenous undergraduates' learning and career opportunities in the global programming market. Future research could explore specialised interventions tailored to indigenous learners' unique needs and perspectives.

The present study investigates the efficacy of the guided learning approach in promoting self-directedness among first-year, first-semester university students in Malaysia. Based on a sample of 37 participants, this study employs the SECI (Socialization, Externalization, Combination, and Internalization) Model as a theoretical framework to examine the transfer of knowledge between the lecturer and students, as well as among students. Using an SDL (Self-Directed Learning) Questionnaire, the study assesses the students' level of self-directed learning in the early stages of the semester and then again following the implementation of the guided learning approach throughout the remainder of the semester. The results of this study reveal that the guided learning approach has a substantial positive impact on students' self-directedness, with 94.59% of the participants exhibiting an increase in their SDL level by the end of the semester. These findings reinforce the notion that a guided learning approach is crucial in fostering self-directedness among first-year, first-semester university students in Malaysia and, more broadly, highlight the importance of fostering self-directed learning in higher education.

This paper explores the use of gamification in providing solutions to overcome learning problems related to electricity on series and parallel circuits in Science for Primary Year 5. The two primary schools involved were located in the rural districts of Betong and Lubok Antu in Sarawak. The use of game design thinking as a learning approach was utilised to facilitate the creation of educational games. The games produced were inspired by modern and traditional games. Several modifications were re-designed for the game elements to appropriately suit the learning context and logistics involved. The games consisted of both online and physical means of conduct where participants were able to collaborate between two schools as well as among themselves as a group. The findings obtained by the participants as the players of the games revealed the effectiveness of the games with the combination of computer-supported and collaborative learning in helping them understand the Science topic through play. Additionally, the implementation of online communication, collaborative activities, and sharing of knowledge was accomplished between the two schools via the Internet.
CORPO, IMAGEM E REPRESENTAÇÃO ICÔNICA NA LINGUAGEM DO VIDEOCLIPE
Authors: Wosniak Cristiane do Rocio
Published: March 2023

Neste artigo, apresento uma possibilidade analí­tica do í­cone cinético, ou seja, do corpo em movimento no videoclipe – signagemvideográfica contemporânea – alicerçada pelos pressupostos da Teoria Geral do Signos de Charles Sanders Peirce. Enquanto signagem hí­brida, o videoclipe será apresentado em suas instâncias relacionais das três matrizes de linguagens, a visual, a sonora e a verbal que se entretecem na construção de sentido por meio da ação sí­gnica. Tomo comocorpusde análise, o videoclipePower(2010) do cantor estadunidense,Kanye West, dirigido pelo cineasta Marco Brambilla. Além da semiótica peirceana, procuro embasamento nas concepções teóricas de Décio Pignatari, Lúcia Santaella e Denise Azevedo Duarte Guimarães, com o objetivo de explicar o argumento de que ocorre, neste objeto de estudo em particular, uma espécie detradução icônica, aproximando-o, pela intervenção do paradigma pós-fotográfico, do conceito de videoarte multimidiática, propí­cio à intervenção e instauração de novas significações.
CONTORNOS DA FIGURA FEMININA NA OBRA DE GUSTAV KLIMT: O MITO DESNUDADO
Authors: Wels Érica Schlude
Published: March 2023

RESUMOO presente artigo parte da análise da obra do pintor Gustav Klimt (1862-1918), lí­der do movimento da "Secessão" , e figura da "Modernidade Vienense" . No panteão de Klimt, predomina a figura feminina, em sua nudez naturalista, banhada por elementos simbólicos, ornamentos dourados e mosaicos que se expandem até o infinito, tornando-se a marca do Jugendstil (Art Noveau); o uso do dourado, a profusão de flores, ilustram a opulência e a decadência, a permanência e a fugacidade – uma face da estética europeia no apagar das luzes do século XIX e alvorecer do século XX. Os mitos são uma fonte inesgotável para as metáforas presentes nas pinturas, seja na forma de narrativas e suas personagens, seja como grandes temas. Além da obra em questão, pretende-se retratar aspectos da trajetória de outro "vienense" [1], contemporâneo de Klimt, Sigmund Freud (1856-1939), estabelecendo entre ambos pontos de contato, notadamente dialógicos.[1] O uso de aspas, aqui, destina-se a enfatizar que Freud não é natural de Viena, mas sim da Moravia, hoje parte da República Tcheca. Austrí­aco, Klimt nasceu na cidade de Baumgarten, próxima à capital. Viena foi um centro cultural, polí­tico e econômico considerável, capital do Império Austro-Húngaro (1867-1918), atraindo inúmeras famí­lias em busca de trabalho e melhores condições de vida. A biografia de ambos apresenta esse ponto de interseção; ao tornarem-se personagens conhecidas da vida na capital do Império, tanto Klimt quanto Freud misturam-se ao quadro vienense do fin-de-siècle.

A MATEMÁTICA E O MUNDO AUTÍSTICO DE SOFIA: UMA DISCUSSÃO DE NUMERALIZAÇÃO A PARTIR DA TEORIA DAS AÇÕES MENTAIS POR ETAPAS
Authors: Cordeiro Janivaldo Pacheco , Resende Allana , Thiengo Edmar
Published: March 2023

Este estudo propôs uma intervenção no processo de aprendizagem de uma aluna autista referente ao conceito de número baseado na Teoria das Ações Mentais por Etapas. O Transtorno do Espectro Autista (TEA) é caracterizado por um conjunto de sintomas que afeta as áreas da socialização, comunicação e comportamento, e, dessas, a mais comprometida é a interação social. Em razão disso, buscou-se em Galperin o aporte teórico-metodológico para analisar e discutir os resultados advindos do processo de aprendizagem, uma vez que o teórico compartilha as ideias da psicologia histórico-cultural. A pesquisa foi realizada numa escola pública de Vila Velha – ES, tendo como sujeito participante Sofia, atendida na sala do Atendimento Educacional Especializado (AEE). Os resultados apontam a necessidade de o docente conhecer as características da síndrome, comotambém as peculiaridades da aluna. Não é possível afirmar que Sofia dominou o conceito do número um, todavia o uso da Teoria das Ações Mentais por Etapas possibilitou a materialização da ação a ser internalizada, haja vista que faz parte de uma de suas etapas. Além disso, percebeu-se com Sofia que sua aprendizagem pode ser expressa em momentos diferentes daqueles em que está sendo ensinada;suas respostas nem sempre correspondiam às perguntas feitas naquele momento.
A Música Como uma Prática Inclusiva na Educação
Authors: Lemos Cristina , Silva Lydio Roberto
Published: March 2023

Este estudo trata da prática musical na escola como uma experiência inclusiva. O termo inclusão utilizado neste documento não necessariamente está atrelado à educação especial. Refere-se sim ao processo de acolhimento das mais variadas e diferentes formas de pensar, sentir e fazer música. Isto é, uma vivência musical em que a dimensão humana é o princípio e o fim de todas as ações. Por isto, esta produção, que é parte da pesquisa de seus autores, propõe uma reflexão educacional que considere a diversidade, a interculturalidade e a questão da tecnologia como fatores interdependentes e constituintes de um cenário com muitas possibilidades educativas. Esta reflexão está apoiada em alguns dos mais significativos autores da Educação Musical no Brasil e apresenta também um breve relato sobre o trabalho desenvolvido nos anos 90, junto a crianças oriundas de escolas públicas e privadas da cidade de Curitiba que apresentava como proposta a educação musical por meio do canto e da experiência da Música Popular Brasileira, em um ambiente onde se priorizou o amor à música, bem como o respeito e o acolhimento pleno das diferenças pessoais e culturais dos participantes.

Published: March 2023

Estudo extraído de tese de doutorado que investigou a implementação dos Encontros Musicais, estratégia grupal de cuidado que estimula a expressão musical e diálogos entre clientes em tratamento de quimioterapia e seus familiares. Este recorte tem por objetivo analisar a função da música no desenvolvimento dos encontros, a partir dos sentidos atribuídos pelos participantes. A análise musical foi baseada nos níveis das experiências musicais e nos espaços de identificação, desenvolvidos por Even Ruud. A pesquisa qualitativa foi desenvolvida segundo a metodologia da Pesquisa Convergente-Assistencial. Os participantes foram 27 pacientes adultos em tratamento de quimioterapia em um hospital na cidade do Rio de janeiro e seus familiares. As músicas escolhidas pelos participantes estiveram vinculadas aos níveis sintático, semântico e pragmático. Os espaços de identificação dos sujeitos, de maior relevância, foram o pessoal e o transpessoal, pois contribuíram para o desenvolvimento de rede de apoio.
