RESUMO

The production efficiency factor is widely used to measure the zootechnical performance of a batch of broilers. The unit cost of production brings new elements to improve efficiency evaluation and financial sustainability for this activity in agriculture. This research aims to evaluate the production efficiency level of the crop to maximize the return on investment. This study uses Data Envelopment Analysis (DEA) with the computational processing of the SIAD software (Integrated Decision Support System). The variables selected were poultry housing, age at slaughter, feed consumed, mortality, and unit cost. The chosen output variable was the total available weight. The analysis spans 31 decision-making units (DMUs) composed of integrated producers, unveiling a frontier of efficiency delineated by the most exemplary DMUs. Notably, only two DMUs, specifically DMU 4 and DMU 23, approached the threshold of maximum relative efficiency. This research illuminates the critical role of unit cost in enhancing the assessment of production efficiency and financial sustainability within the agriculture environment. By setting benchmarks for efficient management and operational protocols, our findings serve as a cornerstone for improving practices among less efficient DMUs, contributing significantly to the literature on agricultural efficiency and offering actionable insights for the poultry farming sector.

RESUMO

OBJECTIVES: In celebration of the journal's 50th anniversary, the aim of the study was to review the whole collection of Community Dentistry and Oral Epidemiology (CDOE) publications from 1973 to 2022 and provide a complete overview of the main publication characteristics. METHODS: The study used bibliometric techniques such as performance and science mapping analysis of 3428 articles extracted from the Scopus database. The data were analysed using the 'Bibliometrix' package in R. The journal's scientific production was examined, along with the yearly citation count, the distribution of publications based on authors, the corresponding author's country and affiliation and citation count, citing source and keywords. Bibliometric network maps were constructed to determine the conceptual, intellectual and social collaborative structure over the past 50 years. The trending research topics and themes were identified. RESULTS: The total number of articles and average citations has increased over the years. D Locker, AJ Spencer, A Sheiham and WM Thomson were the most frequently published authors, and PE Petersen, GD Slade and AI Ismail published papers with the highest citations. The most published countries were the United States, United Kingdom, Brazil and Canada, frequently engaging in collaborative efforts. The most common keywords used were 'dental caries', 'oral epidemiology' and 'oral health'. The trending topics were healthcare and health disparities, social determinants of health, systematic review and health inequalities. Epidemiology, oral health and disparities were highly researched areas. CONCLUSION: This bibliometric study reviews CDOE's significant contribution to dental public health by identifying key research trends, themes, influential authors and collaborations. The findings provide insights into the need to increase publications from developing countries, improve gender diversity in authorship and broaden the scope of research themes.

RESUMO

Abstract Tactical aspects play a significant role in soccer, as a team sport, considering the inherent unpredictability of the actions during a game. Therefore, measuring tactical variables is essential for training planning in soccer and other team sports. However, previous studies have interchangeably used the terms "tactical behavior" and "tactical performance" to refer to the collected variables, which has become a source of questioning in recent literature. In this point-of-view article, the tactical behavior and tactical performance concepts are defined, discussed, and exemplified based on previous studies. While tactical behavior measures are associated with descriptions of the actions, tactical performance variables are assumed to classify and interpret such behaviors considering reference values. Finally, examples of instruments for collecting each data are provided.

Resumo Aspectos táticos representam um ponto chave no futebol enquanto um esporte coletivo considerando a imprevisibilidade das ações durante um jogo. Medir variáveis táticas é importante para o planejamento do treinamento no futebol e nos outros esportes coletivos. Estudos prévios, contudo, utilizaram de forma intercambiável os termos "comportamento tático" e "desempenho tático" para se referir às variáveis coletadas, o que se transformou em um ponto de dúvida na literatura recente. Neste artigo de ponto de vista, os conceitos de comportamento e desempenho tático são definidos, discutidos e exemplificados com base em estudos prévios. Enquanto comportamento tático está associado à descrição das ações, o desempenho tático é assumido como a classificação e a interpretação destes comportamentos considerando valores de referência. Finalmente, exemplos de instrumentos para a recolha de cada dado são apresentados.

RESUMO

Resumo A Análise de Desempenho e a Pedagogia do Esporte são áreas de conhecimento que apontam caminhos para a melhora da prática esportiva. O presente artigo buscou identificar o papel pedagógico na atuação dos analistas de desempenho das categorias de base dos clubes brasileiros. A pesquisa, de abordagem qualitativa, utilizou o procedimento de análise de Triangulação de Métodos, a partir de entrevistas semiestruturadas com dez analistas de desempenho das categorias de base dos clubes brasileiros de futebol masculino da série A (2020). Conclui-se que embora os analistas não percebam a sua atuação dentro dos clubes como de cunho pedagógico, na prática essa interface vem sendo necessária no desenvolvimento do trabalho destes profissionais. Dessa maneira o diálogo entre as áreas da Pedagogia do Esporte e da Análise de Desempenho pode contribuir para qualificação e atuação profissional dos analistas de desempenho, potencializando o processo de formação de jovens jogadores de futebol.

Abstract Performance Analysis and Sport Pedagogy are areas of knowledge that point to ways to improve sports practice. This article sought to identify the pedagogical role in the performance of performance analysts of the base categories of Brazilian clubs. The research, with a qualitative approach, used the Triangulation of Methods analysis procedure, based on semi-structured interviews with ten performance analysts from the basic categories of Brazilian men's soccer clubs in the series A (2020). It is concluded that although the analysts do not perceive their performance within the clubs as pedagogical, in practice this interface has been necessary in the development of the work of these professionals. In this way, the dialogue between the areas of Sport Pedagogy and Performance Analysis can contribute to the qualification and professional performance of performance analysts, enhancing the process of training young soccer players.

RESUMO

As a result of the COVID-19 pandemic, the Brazilian Serie A championship was played without crowds in 2020 and partially in the 2021 season. We verified if the home advantage (HA) was different between the 2018, 2019, 2020, and 2021 seasons. We also compared the HA, performance, and disciplinary aspects between the rounds with or without crowds and verified the association between the number of absent athletes because of health protocols and the HA in the 2020 and 2021 seasons. We calculated the HA using the Pollard method. The performance aspects were goals, corners, shots, and ball possession, and the disciplinary aspects were fouls, yellow cards, and red cards. The HA was higher in the 2018 season compared with the other seasons. The rounds with crowds showed higher HAs than the two previous seasons and the teams had more shots and scored more goals than in the rounds without crowds. There were 457 athletes in the 2020 season and 123 athletes in the 2021 season who were absent because of health protocols, and there was no association between absence and HA. The COVID-19 pandemic affected soccer in the two last seasons in different ways in the Brazilian Serie A championship.

Meli Neto, B., Fuini Puggina, E., Pombo Menezes, R., Cláudio Machado, J., Vanella, R., y Aquino, R. (2022). Análisis de redes sociales en el deporte desde el punto de vista del enfoque ecológico. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-21. El análisis del rendimiento está relacionado con la pedagogía del deporte. Las bases teóricas que sustentan las selecciones metodológicas deben estar bien establecidas para que haya una convergencia entre los instrumentos de evaluación y el proceso de enseñanza y entrenamiento. Este ensayo pretende presentar y discutir la importancia y representatividad del análisis de redes sociales para evaluar el rendimiento en los deportes de equipo. El objetivo principal del análisis de redes sociales es estudiar la relación entre los jugadores para identificar las posibles causas y consecuencias de los eventos durante el partido. Así, el análisis de redes sociales es diferente de los análisis tradicionales, en los que el foco principal está en el sujeto, o de los análisis notacionales, que son más utilizados y acumulan la frecuencia de los eventos ocurridos (por ejemplo, los goles marcados, la posesión del balón, las zonas de remate). Esta herramienta de evaluación, posicionada teóricamente en un enfoque ecológico, se muestra eficaz para la identificación de los patrones de interacción en un grupo y la comprensión de los artificios sociales que ayudan a entender el rendimiento de un equipo. Así, los equipos pasan a ser analizados como grupos sociales y no como sujetos aislados. En este ensayo también se exponen las principales aplicaciones prácticas de esta herramienta de evaluación en diferentes deportes de equipo como el fútbol, el fútbol sala, el balonmano, el baloncesto y el voleibol.

Meli Neto, B., Fuini Puggina, E., Pombo Menezes, R., Cláudio Machado, J., Vanella, R., & Aquino, R. (2022). Social networks analysis in sports through an ecological approach—a theoretical framework. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-21. Performance analysis is a discipline that is closely related to the pedagogy of sports. The theoretical foundations that undergird methodological choices must be well established in order for a convergence to exist between evaluation instruments and the process of teaching and training. The objective of the present theoretical study was to present and discuss the importance and representativeness of social networks analysis in order to evaluate the performance in group sports. The main purpose of social networks analysis is to study the relationships among players, in order to identify possible causes and consequences of the events that took place during a match. Thus, the analysis of social networks works differently from traditional analyses, whose major focus is on the subject, or in notational analyses that are most commonly used and that look for the accumulation of frequency of the events that have occurred (e.g., goals scored, ball possession, finishing zones). Such an instrument of evaluation, theoretically positioned on an ecological approach, proves effective for the identification of interaction patterns in a group and for understanding the social artifices that help to understand performance in a team. Thus, teams come to be analyzed as social groups instead of isolated individuals. This study also presents the main practical applications of this evaluation instrument in different group sports such as soccer football, indoor soccer, handball, basketball and volleyball.

RESUMO

This data article provides raw log files captured from automated computational experiments with an application integration platform that implements the task-based execution model. The code of a well-known enterprise application integration process was modified to record these data while running the experiments. The dataset described in this article is related to the research article entitled "On the Analysis of Makespan and Performance of the Task-based Execution Model for Enterprise Application Integration Platforms: an Empirical Study" of Frantz et al. (2021). The dataset contains two types of CSV files in text format presenting: (1) data of makespan related to experiment executions and (2) data regarding the number of messages and work-units processed during each experiment. Scientific community who works on workflow and integration process execution can benefit from these data to analyse and understand the behaviour of the task-based execution model, obtain insights to improve this model, as well as perform comparisons with other types of execution models or platforms.

RESUMO

Isokinetic tests have been highly valuable to athletic analysis, but their cost and technical operation turn them inaccessible. The purpose of this study was to verify the correlation between unilateral countermovement jump variables and isokinetic data. Thirty-two male professional soccer players were subjected to the isokinetic testing of both knee extensors and flexors in concentric and eccentric muscle contractions. They also executed unilateral countermovement vertical jumps (UCMJ) to compare maximum height, ground reaction force, and impulse power with isokinetic peak torque. Data analysis was conducted through Pearson correlation and linear regression. A high correlation was found between dominant unilateral extensor concentric peak torque and the UCMJ maximum height of the dominant leg. The non-dominant leg jump showed a moderate correlation. No other variable showed statistical significance. Linear regression allowed the generation of two formulae to estimate the peak torque from UCMJ for dominant and non-dominant legs. Although few studies were found to compare our results, leading to more studies being needed, a better understanding of the unilateral countermovement jump may be used in the future as a substitute to the expensive and technically demanding isokinetic testing when it is unavailable, allowing the assessment of lower limb physical asymmetries in athletic or rehabilitation environments.
