Impact of bullying on academic performance. A case study for the Community of Madrid

Bullying is a problem that affects children and teenagers around the world and its repercussions can endure throughout adult life. Its prevalence is, in part, a product of the lack of information and the paucity of studies which analyse the wide-ranging consequences for the individuals involved. The main objective of this research is to study the incidence of bullying on the academic performance of students in education centres in the Madrid Region. The databases used are those of Competency Tests carried out on all 10th grade students in Madrid during the year 2017. These external assessment tests evaluate Spanish language, English language, Mathematics, and Geography and History. Along with these tests, the students, their families, their teachers and head teachers complete comprehensive questionnaires. To analyse all these data, we carry out a multilevel methodological approach to identify the quantitative association of bullying with academic performance and to estimate the probability that performance is affected by the level of bullying that exists in the education centres. The results indicate that bullying has a negative impact on all the competencies evaluated, that the probability of a lower academic performance increases in environments where there is bullying and that bullying can affect students with low or high academic achievement in different ways, depending on what competency is evaluated

PROPOSING A METHOD TO CREATE METACOGNITIVE SCHOOL EXAMS

Metacognition is defined as the capacity of the persons to monitor, to regulate and to construct knowledge about their inner processes. Theoretically, this construct is relevant to Education and correlated areas, since the process of learning and knowledge construction involves metacognition. Besides, there are evidences that certain metacognitive components are predictors of academic achievement of the students. Regarding these aspects, this paper proposes a methodology that permits educators to elaborate metacognitive school exams, which are capable of measuring both the students' knowledge of an educational domain (i.e., concepts pertaining to biology, chemistry, history, mathematics, physics, and so on), and the following metacognitive abilities: feeling-of-knowing, monitoring (detection of errors), self-management, and judgment. In this paper, we present the methodology stressing on the steps that enable the teacher to elaborate a school exam capable of measuring a target educational domain, as well as the stated metacognitive abilities. Concomitantly, we apply this methodology, showing the construction of the Metacognitive School Exam in Electrostatics.  Article visualizations

Importância dos Fatores Não-tecnológicos na Implementação do CPFR

According to the Voluntary Interindustry Commerce Standards [VICS], Collaborative Planning, Forecasting, and Replenishment [CPFR] is based on the standardization, registration and electronic synchronization of data, supported by collaborative management among companies (VICS, 2004). Based on this definition, it can be concluded that there are two dominant factors in the implementation of CPFR: one essentially technological and the other non-technological. In this context, the main purpose of this study is to identify the so-called nontechnological factors involved in CPFR reported in the literature and to analyze them in real situations. The importance of these factors is then analyzed through the study of two real cases of CPFR implementation, the first in a large fast food network and the second at a wholesale food distributor operating in Brazil. The main findings indicate that the demand forecast conducted by the company that coordinates CPFR carries the most weight in the understanding of demand by the companies of the whole supply chain, that the collaborative culture is considered a very important factor in the relationships along the chain (albeit not essential to the implementation of processes), and that the monitoring of activities is fundamental in aligning the companies with CPFR management

Modelação 3D de grutas

A representação computacional de objetos espaciais complexos, como é o caso de grutas, possui variados campos de aplicações em domínios técnicos, científicos e artísticos. A construção destas representações envolve múltiplas tecnologias de aquisição e processamento de grandes conjuntos de dados. O presente trabalho apresenta um caso prático de criação de um modelo 3D do interior da gruta Algar do Penico (Algarve, Portugal) a partir de um levantamento por laser scanning terrestre (LST), com objectivo de identificar e cartografar estruturas geomorfológicas. Além do objectivo principal, a concepção de um modelo tridimensional permite reconstruir ambientes realistas para aplicações no domínio da criação artística, como por exemplo, animação 3D e Realidade Virtual

Framework for 3D data modeling and Web visualization of underground caves using open source tools

Terrestrial Laser Scanning is a very useful technique for cave studies. This surveying method creates point clouds with high detail levels for 3D model generation, which is indeed useful for either reconstruction, geomorphological studies or virtual visits of caves. The present work generated a 3D model of a cave chamber and developed a framework for 3D data visualization on the Web. Identifying geomorphological structures is one of the goals of this project. The generated 3D-mesh represents the surface model of the cave chamber, which is important to study its geomorphological features. A topological structure of the 3D-mesh was implemented to get an efficient algorithm to help determining stalactites. The recognition and positioning of cave stalactites can provide information on hidden cave features responsible for cave geomorphology. The possibility to publish 3D data on the Web is of particular interest for the geospatial field. For this reason, it was decided to make the cave model available in the Web by developing a 3D graphical interface where users can navigate and interact with the threedimensional models of the cave. For this Web framework, X3D, WebGL and X3DOM were used. Such solution does not require any additional plug-ins or components

High-resolution digital 3D models of Algar do Penico Chamber: limitations, challenges, and potential

The study of karst and its geomorphological structures is important for understanding the relationships between hydrology and climate over geological time. In that context, we conducted a terrestrial laser-scan survey to map geomorphological structures in the karst cave of Algar do Penico in southern Portugal. The point cloud data set obtained was used to generate 3D meshes with different levels of detail, allowing the limitations of mapping capabilities to be explored. In addition to cave mapping, the study focuses on 3D-mesh analysis, including the development of two algorithms for determination of stalactite extremities and contour lines, and on the interactive visualization of 3D meshes on the Web. Data processing and analysis were performed using freely available open-source software. For interactive visualization, we adopted a framework based on Web standards X3D, WebGL, and X3DOM. This solution gives both the general public and researchers access to 3D models and to additional data produced from map tools analyses through a web browser, without the need for plug-ins

Cave chamber data modeling and 3D Web visualization

Underground caves and its specific structures are important for geomorphological studies. In this paper we present tools to identify and map speleothems by surveying cave chambers interiors. The cave chamber was surveyed using Terrestrial Laser Scanning to acquire point clouds with high level of detail for 3D model generation. This data with 45 million points is useful for either reconstruction, geomorphological studies or virtual visits of caves. With this point cloud we generated a 3D-mesh to represent the surface model of the cave chamber, which is important to study its geomorphological features. A topological structure of the 3D-mesh was also implemented to get an efficient algorithm to help identifying stalactites. The possibility to publish 3D data on the Web is of particular interest for the geospatial field. For this reason, it was decided to make the cave model available in the Web by developing a 3D graphical interface where users can navigate and interact with the three-dimensional models of the cave. For this Web3D framework it was used X3D, WebGL and X3DOM. Such solution does not require any additional plug-ins or components

A topological framework for interactive queries on 3D models in the web

Several technologies exist to create 3D content for the web. With X3D, WebGL, and X3DOM, it is possible to visualize and interact with 3D models in a web browser. Frequently, three-dimensional objects are stored using the X3D file format for the web. However, there is no explicit topological information, which makes it difficult to design fast algorithms for applications that require adjacency and incidence data. This paper presents a new open source toolkit TopTri (Topological model for Triangle meshes) for Web3D servers that builds the topological model for triangular meshes of manifold or nonmanifold models. Web3D client applications using this toolkit make queries to the web server to get adjacent and incidence information of vertices, edges, and faces. This paper shows the application of the topological information to get minimal local points and iso-lines in a 3D mesh in a web browser. As an application, we present also the interactive identification of stalactites in a cave chamber in a 3D web browser. Several tests show that even for large triangular meshes with millions of triangles, the adjacency and incidence information is returned in real time making the presented toolkit appropriate for interactive Web3D applications
