Authors: Silva Ivanderson Pereira da , Nunes Emanuelly Torres
Published: April 2024

Neste artigo, socializamos os resultados obtidos em duas práticas experimentais utilizando o smartfone e o software Tracker, presente em uma sequência didática de seis etapas/aulas sobre o estudo do fenômeno da queda dos corpos, sob a ação da gravidade, no contexto do ensino médio. Para isso, desenvolvemos, realizamos e analisamos a sequência didática intitulada “Estudo da queda de objetos, na direção vertical sobre o efeito da gravidade com o software Tracker”. Trata-se de uma pesquisa participante na qual a docente-pesquisadora foi coautora da sequência didática. Essa sequência didática foi desenvolvida junto aos estudantes das turmas da 1ª série do ensino médio de uma escola pública do agreste alagoano. O estudo tem como principal objetivo analisar os limites e possibilidades da utilização do smartfone e do software Tracker no processo de experimentação no Ensino de Física em turmas da 1ª série do Ensino Médio. Delinearam-se os seguintes objetivos específicos: explorar as potencialidades da prática experimental convencional e por meio da videoanálise, relacionar duas práticas experimentais no estudo de um mesmo movimento, e assim, analisar a propagação de erros no processo de experimentação. Partindo desse escopo, buscou-se responder ao seguinte problema de pesquisa: quais os limites e possibilidades da experimentação com a utilização do cronômetro do smartfone, da experimentação por meio da videoanálise utilizando o software Tracker, e da associação dessas duas práticas experimentais? Com o intuito de responder ao problema de pesquisa e alcançar os objetivos traçados, se desenvolveu um estudo analítico dos dados obtidos pelos estudantes nas duas práticas experimentais, que foram recolhidos por meio de ficha de coleta de dados (Etapa 1) e por planilha eletrônica (Etapa 5). Essa pesquisa e formação se deu pela vivência, do desenvolvimento, do planejamento, da execução, da análise da sequência didática, e de vivenciar todo esse percurso. Possibilitando assim, evoluir, quanto docente, em metodologias envolvendo a experimentação no Ensino de Física, mediando os estudantes na busca do conhecimento de forma ativa, crítica e reflexiva sobre os fatores que influência na propagação de erros e medidas em atividades experimentais
CIENCIA Y SEXUALIDAD EN LA FORMACIÓN DEL PROFESORADO: REFLEXIONES DESDE LA PRÁCTICA DE DOCENTES FORMADORES DE MAESTROS
Authors: Mosquera Jonathan Andrés , García José Joaquín , Pansera-de-Araujo Maria Cristina
Published: April 2024

La formación inicial del profesorado es un factor que incide en el desarrollo de sus prácticas de aula y los procesos de enseñanza y aprendizaje en torno a conceptos propios del saber disciplinar y su articulación con distintos fenómenos culturales. De ahí que, se desarrolló un estudio de naturaleza cualitativa con docentes formadores de maestros de ciencias naturales al interior de un programa de licenciatura en el sur de Colombia. El objetivo ha sido reconocer las concepciones y las prácticas del profesorado formador, en torno a la vinculación de la sexualidad y la afectividad con la educación en ciencias. De esta manera, se aplicó una entrevista semiestructurada sobre los ejes temáticos de interés; las respuestas fueron sistematizadas y analizadas a través de la técnica de Análisis Textual Discursivo mediante un sistema de categorías. Los resultados permiten afirmar que, el profesorado construye sus prácticas de aula con los docentes en formación desde una perspectiva eugenésica de la sexualidad, limitándose a contenidos de tipo biologicista y fuertemente articulados a las ciencias experimentales. Es decir, que la ciencia y la sexualidad al interior del programa de formación docente se articulan bajo un enfoque asignaturista, que privilegia las prácticas heteronormativas y promueve en los futuros profesores de ciencias naturales una visión patriarcal de la sexualidad y su enseñanza.

Published: April 2024

Compreender a Sociedade atual e o papel da Tecnologia e Ciência exige que se tome como objeto de investigação as próprias inter-relações entre a tríade Ciência, Tecnologia e Sociedade. Nesse sentido, este estudo buscou identificar as interações percebidas entre Tecnologia na Ciência e Sociedade na visão de professores em formação inicial dos cursos de Licenciatura em Ciências Biológicas, Química e Física da Universidade Federal do Rio Grande do Norte (UFRN) e Instituto Federal do Rio Grande do Norte (IFRN). A pesquisa é de abordagem qualitativa. Participaram 75 licenciandos. Utilizou-se como instrumento um questionário. Para interpretação das respostas empregou-se o método Análise Textual Discursiva. Infere-se que os professores em formação inicial percebem a Tecnologia e suas relações com a Ciência e Sociedade, alinhados ainda a um discurso que se adere a concepção do modelo linear de desenvolvimento. Mencionam-se ainda que denotam a prevalência de concepções instrumentalistas, seguida de concepções deterministas, salvacionistas e utilitaristas de Tecnologia. Discursos mais amplos e críticos sobre Tecnologia foram menos identificados. Sinaliza-se, que a implementação de Dimensões Tecnológicas, aspectos da Teoria Crítica da Tecnologia, História e Filosofia da Tecnologia, Alfabetização Tecnológica e Natureza da Tecnologia na abordagem da Educação CTS nas disciplinas pedagógicas dos cursos de Licenciatura de Ciências, podem ser caminhos que auxiliem a construção de concepções amplas e críticas sobre Tecnologia e suas relações com a Ciência e a Sociedade.

Background: Lateral epicondylitis, commonly known as tennis elbow, is characterized by pain and functional limitations at the elbow due to overuse. This study focuses on evaluating the effects of Tyler twist wrist extensor-strengthening exercises, aiming to provide insights into an effective intervention for this condition. Objective: This study aimed to determine the effects of Tyler twist wrist extensor strengthening exercises on pain, disability, and grip strength in patients with lateral epicondylitis. Methodology: A randomized controlled trial was conducted at Cina Medical Center Rawalpindi from February 2022 to January 2023. Fifty-two participants meeting the inclusion criteria were assigned to either Group A or Group B. Group A received eccentric Tyler twist exercises in addition to conventional physiotherapy, while Group B received conventional physiotherapy alone. Pain, functional disability, and grip strength were assessed at baseline, the second week, and the fourth week. Data was analyzed with SPSS version 25. Demographics and descriptive data is presented in form of percentages, frequencies and mean + SD. Normality of the data is determined via Shapiro Wilk Test. We applied mixed-way ANOVA to find the interaction between two groups. R e s u l t s : Within-group analysis demonstrated a significant improvement in pain, functional disability, and grip strength for both groups (p-value < 0.01). Between-group analysis revealed a significant difference in pain, functional disability, and grip strength. Conclusion: The addition of eccentric Tyler twist exercises to conventional therapy showed a statistically significant difference in terms of pain, functional disability, and grip strength in patients with lateral epicondylitis.
Analysis of recent inflation dynamics in Spain. An approach based on the Blanchard and Bernanke (2023) model
Authors: Ghomi Morteza , Hurtado Samuel , Montero José Manuel
Published: April 2024

The recent inflationary episode is the result of a series of shocks that have taken place over a short period of time. In this article we use the Blanchard and Bernanke (2023) model as an analytical framework to assess the relative importance of different factors over the course of this episode. Two main conclusions can be drawn from our results. First, supply-side shocks (related to energy, food and bottlenecks) have played a major role in recent inflation developments in the Spanish economy. Second, now that these supply shocks have been absorbed, labour market tightness is becoming more important as a determinant of wage inflation, with a pass-through to prices that has been limited so far but that, if it intensifies, could generate risks with a higher degree of persistence.

Published: April 2024

The world population is expected to grow by 2 billion people over the next 30 years, from the current 7.7 billion individuals to 9.7 billion in 2050, according to the United Nations - UN. In another UN report, The State of Food and Nutrition Security in the World (UN, 2022), it provided alarming data on the situation of food insecurity in the world. According to the “Panorama of Food and Nutritional Security 2022”, the number of people impacted by hunger in 2021 exceeded 46 million, data from 2020. In this context, urban agriculture gained visibility as a tool to mitigate the problem of food security (Bozetti, 2022). In parallel, Germany suggested industry 4.0, which presented the concepts and technologies of Artificial Intelligence (AI) and the Internet of Things (IoT). This study addresses the applicability of the concepts inherent to the Internet of Things (IoT) and Artificial Intelligence (AI) in the use of sustainable organic food agriculture in homes, by people without in-depth knowledge of agricultural techniques, in addition to contributing to minimizing the problem of food insecurity and contribute to the triple bottom line (TBL).

This article deals with the issue of the inclusion of people with disabilities in the Training Course for Officers of the Fire Department (CFO-BM) and the Military Police of Maranhão (CFO-PM), at the State University of Maranhão (UEMA). In this context, the main objective of this study is to analyze the main challenges to be overcome so that people with disabilities have the right to access, remain in and complete the CFO-BM and the Military Police of Maranhão at UEMA. In order to achieve the proposed objective, an exploratory, descriptive study was carried out with a qualitative approach. The participants were 04 disabled cadets from the CFO-BM; 02 aspiring officers from the Fire Department and 10 disabled cadets from the CFO-PM. The data collection instruments included semi-structured interviews. The research findings reveal that the BM and PM officer training courses are adjusting to issues involving the physical aptitudes of people with disabilities, their needs for specialized educational care and/or adjustments, their potential and vulnerabilities. Cadets with disabilities are bringing visibility to the human potential of people with disabilities. The main challenges to be overcome are the elimination of prejudice and ableism, as well as the lack of accessibility and attitudinal barriers. The inclusion of people with disabilities in the military contributes to the deconstruction of exclusionary paradigms in relation to disability. There is still a long way to go, but the first step has already been taken, let's wait for better outcomes.

The expansion of fish production in a sustainable way in small municipalities has become an objective for both fish farmers and consumers, whether for nutritional and/or environmental appeal. The objective of this work was to map natural resources in the municipality of Chopinzinho/Pr using geotechnology to subsidies the planning of fish production in the municipality. The methodology used was based on geoprocessing and remote sensing tools. Results indicate annual growth in fish production, an amount of 53.1 hectares of water depth and 242 excavated ponds, the majority (81.8%) measuring less than 3,000 meters. The estimated nutrient input, due to fish farming, in excavated ponds, during the cultivation cycle was 104.14 tons of Total Nitrogen and 12.78 tons of Total Phosphorus and during harvesting 3.95 tons of Total Nitrogen and 0,85 tons of Total Phosphorus. Therefore, the use of geotechnology tools to map natural resources and excavated ponds, for subsequent estimation of nutrient input, has the potential to become a methodology to promote the expansion of fish production in a sustainable manner.

Human health and disease are determined by multiple and complex factors. Threats to health are at the human-animal-ecosystems interface. Zoonoses pose risks and costs to public health and if the environment is contaminated, degraded and polluted, more diseases will be transmitted. This article specifically illustrates the importance of diverse paradigms to actual and potential threats to health. More specifically, it intends to discuss the specific aspects of the Sustainable Development Goal (SDG) No 3 (Health and Well-Being) and its correlations with the other SDG`s and implications with the multiple dimensions of sustainability. For this, a search was carried out in the databases, SciELO, PubMed, Scopus, Web of Science; and websites with magazines, ScienceDirect, CAPES Journal Portal. The importance of health is highlighted in the Magna Cartas of the countries, being considered a priority for human dignity. All areas of health are somehow linked to all SDGs, but in this text SDGs 1, 2, 6, 8, 10, 12 and 13 were highlighted. Health is an SDG that is intensive in scientific research and that it needs public policies. Poor quality in health directly affects the sustainability of the environment.

Introduction: The Deliberative Roots and Gender Complementarity in Igbo Political System
Authors:   Institute of African Studies, University of Nigeria Nsukka, Korieh Chima J.
Published: April 2024

One of the most key facts about African political development is the autonomous character of Africa’s political organizations and the relative absence of large polities along Eurasian lines. African communities placed a high value on autonomy and independence. Most were particularly concerned about the abusive potential of centralized authority or consolidation of power within an individual or group of individuals. The Igbo represent a perfect example of how Africans organized themselves into autonomous and democratic political entities and resisted political centralization.

Здійснення зовнішньоторговельної діяльності в умовах, що пов’язані з цифровізацією економічних взаємовідносин між суб’єктами господарювання та швидкими темпами розвитку інновацій, вимагає відповідного забезпечення в системі управління підприємством. Враховуючи різноманітність поглядів на базові економічні категорії, які розкривають сутність даних процесів, виникає необхідність формування сучасного понятійно-категоріального апарату.

Визначено, що в іноземних джерелах для характеристики торговельних операцій використовують поняття «міжнародна торгівля» (international trade), незважаючи на рівень взаємовідносин. Поняття «зовнішньоторговельна діяльність» (foreign trade activity) не має широкого вжитку та за використання вважається синонімом міжнародної торгівлі. Дана категорія також не має достатнього наукового обґрунтування і у вітчизняних джерелах.

У статті надано авторське визначення категорії зовнішньоторговельна діяльність – це сукупність економічних операцій і відносин на мікрорівні, пов'язаних з міжнародним обміном товарів, послуг і фінансових активів підприємств між різними країнами, що містить в собі експортно-імпортні операції, транзит, транскордонні інвестиції, послуги логістики та митні процедури.

Оскільки усі види та форми міжнародної взаємодії та співпраці потребують обробки значних інформаційних масивів даних і формуються під впливом стрімкого розвитку інформаційних технологій та інновацій, доцільно користуватися поняттям «інформаційно-інноваційне забезпечення зовнішньоторговельної діяльності», що являє собою комплекс заходів і технологій, спрямованих на використання інформаційних та інноваційних ресурсів для оптимізації процесів зовнішньоторговельної діяльності, охоплює впровадження сучасних інформаційних систем, аналітичних інструментів, електронної комерції, цифрових платформ та інших технологій для підвищення ефективності торговельних операцій, поліпшення маркетингу та просування товарів і послуг на світових ринках, а також забезпечення конкурентоспроможності на міжнародній арені.
Self-Determination Interventions for Students with Intellectual and Developmental Disabilities Transitioning to Postsecondary Education: A Scoping Review
Authors: Ahmed Gelan Hesham Abdou
Published: April 2024

Students with intellectual and developmental disabilities (IDDs) need a myriad of independent living skills to seamlessly transition to postsecondary education. One of these skills is self-determination. Self-determination is deemed as a combination of knowledge and skills that enables a person to become autonomous. So, the purpose of this scoping review was to explore the interventions that promote self-determination in students with IDDs as they transition to postsecondary education in USA. Arksey’s and O’Malley’s framework guided this scoping review paper. An electronic search was conducted using IU OneSearch. The search was restricted to peer-reviewed studies, books, and eBooks published in English language between 2010 to 2022. Studies were screened at the title and abstract levels, and at full-text level by the author. In total, two studies met the inclusion criteria and were included in this review. Findings showed that curriculum-based and community-based interventions had remarkable potentials in promoting self-determination in students with IDDs who were transitioning to postsecondary education. Implications for research include developing and implementing more curriculum-based and community-based interventions; measuring treatment integrity through checklists; describing implementation procedures to allow for replication studies to be conducted; and utilizing a mixed-methods research design in intervention studies.

É fato que o processo de formação do professor é crescente e contínuo. Como indivíduo, ele se molda a cada dia, em momentos que compõem seu cotidiano, e como educador, ele se define pelo compromisso que estabelece com os alunos e demais membros da comunidade escolar. Nesse contexto, é fundamental abordar a formação de professores no Brasil como um direito fundamental, visando compreender suas necessidades, identificar dificuldades e apontar os desafios enfrentados ao longo de suas jornadas profissionais. Esta pesquisa adota uma abordagem bibliográfica com uma perspectiva qualitativa e quantitativa. Ao explorar essa temática, observa-se a necessidade de um debate mais amplo sobre o assunto, bem como a urgência de investimentos em formação continuada e permanente para os professores. Afinal, é por meio dessas formações que os docentes podem aprimorar suas práticas pedagógicas, impactando diretamente no processo de ensino-aprendizagem. A formação de professores não se limita apenas à aquisição de conhecimentos teóricos; ela também abrange aspectos práticos, emocionais e sociais. É um processo multifacetado que exige constante reflexão e atualização por parte dos educadores. Portanto, é essencial que as políticas educacionais reconheçam a importância desse processo e garantam recursos e suporte adequados para sua efetivação. No contexto brasileiro, os desafios enfrentados pelos professores são diversos. Entre eles, destacam-se a falta de valorização da profissão, baixos salários, condições precárias de trabalho, falta de recursos didáticos adequados e a sobrecarga de tarefas administrativas. Esses obstáculos dificultam o desenvolvimento profissional e impactam negativamente na qualidade do ensino oferecido. Além disso, há a necessidade de promover uma cultura de colaboração e compartilhamento de experiências entre os professores. A troca de conhecimentos e práticas pedagógicas pode enriquecer o trabalho docente e contribuir para a construção de uma comunidade escolar mais coesa e eficaz. Diante desse cenário, torna-se evidente a importância de investir na formação inicial e continuada dos professores, garantindo que eles estejam preparados para os desafios do século XXI. Isso inclui o desenvolvimento de habilidades socioemocionais, o domínio das novas tecnologias educacionais e a capacidade de promover uma educação inclusiva e equitativa.
Using A Semi-Parametric Regression Model to Estimate A Function of The Quantity of Date Production In Iraq
Authors:   Department of Statistics, University of Sumer, Iraq, Kareem Kareem
Published: April 2024

The semi-parametric referral model is one of the important developments that used the analysis of their independent effect on other variables, which produces prediction issues. It is known that the semi-parametric referral model combines direct referral models, whose variables are linear, with analmic conversion models, whose variables are non-linear. In this, it was done. The research presents the production function of the quantity of dates, which is affected by the multiplicities. Some of them control parameters such as heart rate and settings of fruiting palm trees, and some of them behave nonlinearly, such as humidity, temperature, wind, and others, and we take the variable to determine the air temperature. It has been observed that the mean square error of the semi-parametric regression model is less than the mean square error of the parametric regression model, which assumes that all variables behave linearly. This proves the validity of the results in the case of using sample sizes for a set of data generated through simulation experiments, which showed that the regression models are semi-parametric.

Apropos of English learning, vocabulary learning is one of the most essential parts. Thanks to modern technology, recent years has witnessed scads of vocabulary learning apps springing in the app market which include greatly comprehensive functions. However, among those popular apps, some universal handicaps still exist in the design of the review section, for example, the absence of the freedom for the users to classify the cognitive or priority grade of vocabulary and the low effect of some reviewing methods that could not satisfy the need of the language learners to fully master the orthography of words. This paper aims at contriving an app serving as a supplementary part of English vocabulary learning in order to remedy those inadequacies of mainstream applications or other self-learning methods. In this paper, literature study, graphology, and mathematical modelling are involved. Based on Matlab GUI/App Designer, this paper presents a new method to review English words in which users could customize their lexicon, as well as define the priority of each word and practice spelling of vocabulary on an hourly-based system instead of a daily-based one that most of the existing online platforms adopted. Through creating a discrete probability density function for each word, this app could forward a random word in the glossary for users to practice orthography, obeying the probability density distribution that has a mathematical relationship with familiarity and priority of the words as well as the time factor (Ebbinghaus forgetting curve). Thus, users could thoroughly grasp the orthography of target words.

Research on the blockage effect in a shock tube
Authors: Shao Dong
Published: April 2024

The shock tube is a crucial experimental apparatus in the field of explosive impact. Limited research has been conducted on the visualization of the internal flow field in shock tubes under blockage conditions, and there is a lack of comprehensive understanding of the mechanisms behind blockage effects. This paper presents experimental and numerical investigations into the propagation of shock waves inside a shock tube and their interaction with obstructive elements. Blockage effect experiments were conducted on a shock tube test platform, where pressure data were obtained through a pressure monitoring system. Additionally, schlieren imaging technology was employed to visualize the evolution of shock wave fronts. A two-dimensional numerical model of the shock tube was established using Fluent software, and the computed results exhibited excellent agreement with the experimental data, confirming the accuracy of the numerical model. The mechanism of the blockage effect was revealed through analysis of pressure-time curves and images depicting the evolution of shock wave fronts. Furthermore, adjustments to parameters on the validated numerical model allowed for analysis and comparison of different blockage ratios. The results indicate that the disturbance to the flow field caused by the blockage effect is primarily due to the reflection of shock waves between the front surface of the obstructive element and the shock tube wall. This reflection leads to differences in pressure curves compared to free-field conditions, and such differences increase with higher blockage ratios.
European Option Pricing Based on FSDE Driven by Fractional Brownian Motion
Authors: Shu Qingyang
Published: April 2024

In the actual financial market, the classical Black-Scholes (B-S) model cant perfectly describe the process of stock price. Besides, memory effect is an important phenomenon in financial systems. Thus, in this paper, we establish a fractional order stochastic differential equations (FSDE) which is driven by fractional Brownian motion (fBm) to describe the effect of noise memory and trend memory in financial pricing. Finally, we derive a European option pricing formula based on the established model. After conducting an empirical analysis based on the SSE 50ETF, we find that the established model performs better than the traditional one.

Search and Retrieval in Semantic-Structural Representations of Novel Malware
Authors: Musgrave John , Campan Alina , Messay-Kebede Temesguen , Kapp David , Wang Boyang
Published: April 2024

In this study, we present a novel representation for binary programs which captures semantic similarity and structural properties. This representation enables the search and retrieval of binary executable programs based on their similarity of behavioral properties. The proposed representation is composed in a bottom-up approach: we begin by extracting data dependency graphs (DDG), which are representative of both program structure and operational semantics. We then encode each program as a set of graph hashes representing isomorphic uniqueness, a method we have labeled DDG Fingerprinting. We present experimental results of search using k-Nearest Neighbors in a metric space constructed from a set of binary executables. Searches in the dataset are based on the operational semantics of specific malware examples By quantifying behavioral similarity we show that we can recognize patterns of operation in novel malware with functionality not previously identified. We show in addition that the associated metric space allows an adjustable level of resolution. Resolution of the features may be decreased for breadth of search and retrieval, or as the search space is reduced, the resolution may be increased for accuracy and fine-grained analysis of malware behavior. This allows for explainability in the interpretation of fine-grained analysis.

Authors: Kaur Arshmeet , Sarmadi Morteza
Published: April 2024

The innovation of next-generation sequencing (NGS) techniques has significantly reduced the price of genome sequencing, lowering barriers to future medical research; it is now feasible to apply genome sequencing to studies where it would have previously been costinefficient. Identifying damaging or pathogenic mutations in vast amounts of complex, highdimensional genome sequencing data may be of particular interest for researchers. Thus, this paper’s aims were to train machine learning models on the attributes of a genetic mutation to predict LoFtool scores (which measure a gene’s intolerance to loss-of-function mutations). These attributes included, but were not limited to, the position of a mutation on a chromosome, changes in amino acids, and changes in codons caused by the mutation. Models were built using the univariate feature selection technique f-regression combined with K-nearest neighbors (KNN), Support Vector Machine (SVM), Random Sample Consensus (RANSAC), Decision Trees, Random Forest, and Extreme Gradient Boosting (XGBoost). These models were evaluated using five-fold cross-validated averages of r-squared, mean squared error, root mean squared error, mean absolute error, and explained variance. The findings of this study include the training of multiple models with testing set r-squared values of 0.97.
