Models implemented in statistical software for the precision analysis of diagnostic tests include random-effects modeling (bivariate model) and hierarchical regression (hierarchical summary receiver operating characteristic). However, these models do not provide an overall mean, but calculate the mean of a central study when the random effect is eq...

Learning approaches are factors that contribute to sustainability education. Academic stress negatively affects students’ performances in the context of sustainability teaching. This study analyzed how deep and surface approaches could be related to coping with academic stress and gender. An online survey was completed by 1012 university students....

One of the aims of compulsory education is for students to adequately handle basic maths, owing to its importance in their future professional and personal lives. However, mechanical knowledge of an algorithm may not be sufficient to train future citizens with critical and creative thinking if it is not accompanied by a comprehensive understanding...

Although measures such as sensitivity and specificity are used in the study of diagnostic test accuracy, these are not appropriate for integrating heterogeneous studies. Therefore, it is essential to assess in detail all related aspects prior to integrating a set of studies so that the correct model can then be selected. This work describes the sch...

Background: One of the most important concepts within Cognitive Social Theory as framed by Bandura is the perceived self-efficacy; this concept became widespread in 1981 when Mathias Jerusalem and Ralf Schwarzer, using 10 items, established a one-dimensional and universal construct of this scale. The main purpose of this study is to show that the...

Estudios recientes muestran que las actitudes positivas del profesorado hacia las TIC son un factor de incremento de uso e integración curricular. Sin embargo, existe poca investigación focalizada en la diferencia que existe entre estas actitudes positivas hacia las TIC y el uso efectivo en el aula. En contraste con estos estudios, en este trabajo...

Background Method This study addresses the need for a theoretical base to develop more effective early autism spectrum disorders (ASD) detection tools. The structure that underlies early ASD detection is explored by evaluating the opinions of experts on ASD screening tools currently used in Europe. A process of face and content validity was perform...

The association of dietary energy density (ED) and overweight is not clear in the literature. Our aim was to study in 4259 of the PREDIMED trial whether an increase in dietary ED based on a higher adherence to a Mediterranean dietary pattern was associated with 3-year weight gain. A validated 137-item food-frequency questionnaire was administered....

Centrofollicular B Cell lymphomas constitute 25% of non-Hodgkin lymphomas that originate in the skin. They are the second in frequency of those lymphomas with extranodal location after gastrointestinal B lymphomas. The primary cutaneous centrofollicular lymphoma is characterized by the neoplastic proliferation of centrocytes and centroblasts confin...

Background Dietary intervention success requires strong participant adherence, but very few studies have examined factors related to both short-term and long-term adherence. A better understanding of predictors of adherence is necessary to improve the design and execution of dietary intervention trials. This study was designed to identify participa...

Every area of scientific research produces results that must be communicated. Scientists are thus required to present their work and often realize that visual elements (forms, pictures, diagrams, letters and colors) are unavoidable. The correct understanding and mastering of these elements, through various communication media, can determine the eff...
