Neuroscience research has shown that meditation practices have effects on brain structure and function. However, few studies have combined information on the effects on structure and function in the same sample. Long-term daily meditation practice produces repeated activity of specific brain networks over years of practice, which may induce lasting structural and functional connectivity changes within relevant circuits. The aim of our study was therefore to identify differences in FC during the resting state between 23 Sahaja Yoga Meditation experts and (...) 23 healthy participants without meditation experience. Seed-based FC analysis was performed departing from voxels that had shown structural differences between these same participants. The contrast of connectivity maps yielded that meditators showed increased FC between the left ventrolateral prefrontal cortex and the right dorsolateral prefrontal cortex but reduced FC between the left insula and the bilateral mid-cingulate as well as between the right angular gyrus and the bilateral precuneus/cuneus cortices. It thus appears that long-term meditation practice increases direct FC between ventral and dorsal frontal regions within brain networks related to attention and cognitive control and decreases FC between regions of these networks and areas of the default mode network.

This paper compares pair and Mob programming in university courses from students' perceptions of technical and human aspects. Wilcoxon signed rank tests were performed. Results indicated that students preferred pair programming in technical aspects and in a global evaluation they completed.

A completely Lorentz-invariant Bohmian model has been proposed recently for the case of a system of non-interacting spinless particles, obeying Klein-Gordon equations. It is based on a multi-temporal formalism and on the idea of treating the squared norm of the wave function as a space-time probability density. The particle’s configurations evolve in space-time in terms of a parameter σ with dimensions of time. In this work this model is further analyzed and extended to the case of an interaction with an (...) external electromagnetic field. The physical meaning of σ is explored. Two special situations are studied in depth: (1) the classical limit, where the Einsteinian Mechanics of Special Relativity is recovered and the parameter σ is shown to tend to the particle’s proper time; and (2) the non-relativistic limit, where it is obtained a model very similar to the usual non-relativistic Bohmian Mechanics but with the time of the frame of reference replaced by σ as the dynamical temporal parameter.

IntroductionDuring the Coronavirus pandemic, a set of daily stressors are being experienced, all this affects people’s mental health, leading them to have a set of emotional disturbances. Little is known about how people’s age can influence their emotional well-being in the face of prolonged stress generate by the pandemic.ObjectiveTo clarify the presence of emotional aspects such as emotional expressiveness and the frequency of positive and negative affections in people with different age in times of crisis.MethodsThe final sample included 297 Chileans (...) between 22 and 68 years old, recruited through an online survey with the appropriate written informed consent. The study was carried out when the pandemic was spreading in Chile.ResultsThe findings revealed age differences in emotional expressivity and the type of affections experienced. The expression of emotions was more affected by negative affections, the age and the gender of the people. While the avoidance of this emotional expression, by age and affections both positive and negative. Age was a significant predictor of emotional expressiveness.DiscussionFindings suggests that the associations between both variables, varied according to the age group of the people. Furthermore, this finding proposes that although older people are facing the persistent and serious threat of COVID-19, they show better emotional functioning. Which would help to better understand the interaction of both positive and negative life experiences in times of crisis. (shrink)

This study aimed to identify the level of psychological violence in ethnic relationships among students of the National Academic Leveling System (SNNA, derived from Spanish) at Universidad Técnica del Norte (UTN). The research is quantitative, cross-sectional and correlational due to the interaction observed between the variables associated with psychological violence and ethnic identification. A survey of 12 Likert-type questions was applied to students aged 17 years and older, encompassing both men and women representing different ethnicities. The sampling approach was probabilistic (...) with a total of 1.158 participants. Subsequently, the collected data underwent statistical analysis using the Statistical Package for the Social Sciences (SPSS) version 25.0. It allowed the verification of a relationship between psychological violence and ethnic identification, evidencing a moderate level of psychological violence. There is 95% confidence in the level of psychological violence among SNNA students, which is related to the ethnic identification of the population. (shrink)

Lower extremity non-contact soft tissue injuries are prevalent in elite futsal. The purpose of this study was to develop robust screening models based on pre-season measures obtained from questionnaires and field-based tests to prospectively predict LE-ST injuries after having applied a range of supervised Machine Learning techniques. One hundred and thirty-nine elite futsal players underwent a pre-season screening evaluation that included individual characteristics; measures related to sleep quality, athlete burnout, psychological characteristics related to sport performance and self-reported perception of chronic (...) ankle instability. A number of neuromuscular performance measures obtained through three field-based tests [isometric hip strength, dynamic postural control and lower extremity joints range of motion ] were also recorded. Injury incidence was monitored over one competitive season. There were 25 LE-ST injuries. Only those groups of measures from two of the field-based tests, as independent data sets, were able to build robust models [area under the receiver operating characteristic curve score ≥0.7] to identify elite futsal players at risk of sustaining a LE-ST injury. Unlike the measures obtained from the five questionnaires selected, the neuromuscular performance measures did build robust prediction models. The inclusion in the same data set of the measures recorded from all the questionnaires and field-based tests did not result in models with significantly higher performance scores. The model generated by the UnderBagging technique with a cost-sensitive SMO as the base classifier and using only four ROM measures reported the best prediction performance scores. The models developed might help coaches, physical trainers and medical practitioners in the decision-making process for injury prevention in futsal. (shrink)

Objectives To develop and test two educational programmes (interactive and passive) aimed at improving family doctors' (FD) prescribing practices and patient's knowledge and use of non-opioid analgesics (NOA).Methods The educational programmes were conducted in two family medicine clinics by using a three-stage approach: baseline evaluation, design, and implementation of educational activities, and post-programme evaluation. An interactive educational programme (IEP) was compared with a passive educational programme (PEP); both were participated by FDs and patients. The IEP for FDs comprised of workshops, (...) discussion groups, in-service training and guidelines, while for patients the IEP consisted of an interactive session with a video, leaflets and a discussion. The PEP consisted in delivering the guidelines to the FDs and the leaflets to patients. The effect of the programmes on the FDs was measured through the appropriateness of prescriptions and analysed using the differences-in-differences estimator (D-in-D), and on patients through changes in self-medication and in their knowledge about the proper use and adverse events by analysing the inter- and intra-group differences before and after the programmes.Results The IEP obtained better results to improve appropriate FDs prescription of NOA than PEP (D-in-D = 15%). Regarding the patients, the PEP group reached higher reduction of self-medication than the IEP group (13.4% vs. 9.1%); the knowledge of proper NOA use increased by 8.5% in both groups, whereas knowledge of NOA-related adverse events was better in the IEP (39.6%) than in the PEP group (9.2%).Conclusions The IEP was better to improve the doctors' abilities to prescribe NOAs, and both programmes improved patients' knowledge.

El anacronismo, que implica la aplicación de conceptos o ideas de una época a otra, se suele considerar uno de los errores más graves en la narrativa histórica. La corriente historiográfica conocida como historia conceptual es una de las que reconoce y busca evitar este problema. Dentro de este contexto, Elias J. Palti ha defendido la idea de que el concepto de “lo político” se originó en la Era moderna. Según su argumento, utilizar este concepto para analizar sociedades anteriores podría (...) llevar a malentendidos y distorsiones en la comprensión de su funcionamiento. Sin embargo, el objetivo de este trabajo es desafiar esta perspectiva y proponer la posibilidad de aplicar el concepto de “lo político” al estudio de sociedades premodernas. En lugar de rechazar automáticamente la aplicación de conceptos modernos, se busca explorar cómo pueden enriquecer nuestro conocimiento de la historia, incluso en contextos temporales diferentes al suyo de origen.

Este artículo se enmarca en una línea de investigación que pretende analizar el humor como estrategia creativa en el ensayo audiovisual español. Para ilustrar el objetivo propuesto, se han revisado tres largometrajes que, a pesar de su diversidad, encajan, de una u otra forma y con diversos objetivos, en esta manera de enunciación cinematográfica: La casa Emak Bakia (Oskar Alegria, 2012), Mapa (Elías León Siminiani, 2012) y Muchos hijos, un mono y un castillo (Gustavo Salmerón, 2017). Los tres comparten (...) algunas características del ensayo audiovisual (la reflexividad, la escritura del yo y una preocupación estética que llega al cuestionamiento de las propias formas de expresión) y recurren al humor como un recurso para construir sus relatos. Por ello, se han revisado algunas de las características del ensayo audiovisual, se ha analizado el humor como elemento narrativo que se consigue a través de diversas instancias enunciativas y se ha pasado revista a dos recursos al servicio del humor.

Las múltiples estrategias que ofrece el arte contemporáneo, particularmente el de la escena, son revisitados a partir de las formulaciones que, desde hace unos años, creadores, investigadores y académicos están proponiendo. La presencia física y en la realidad virtual, el evento y la extrema realidad, así como la precariedad, debatida y ejecutada en performances y textos de Europa y Estados Unidos han sido el centro de varias discusiones que aquí se actualizan a través de la creación artística de mujeres mexicanas (...) y los entornos en los que se involucran. El seguimiento esta vez enfatiza la construcción de una “vida” que da sentido al mundo, como parte de los procesos de “escrituras” expandidas, donde la “presencialidad”, las mediaciones y la precariedad permiten diálogos con diferentes realidades en las que las nuevas tecno-logías son un soporte relevante a tener en cuenta.

La resolución 466 de 2007, promulgada por el Ministerio de Educación Nacional, representa un avatar sin precedentes en la institucionalización de la Ciencia Política en Colombia. Aunque avanza en la definición de las características específicas de calidad y desarrollo de los programas en materia de metodología, sin embargo no logra establecer una diferenciación clara entre los programas de ciencias sociales. Por esta razón, el presente artículo indaga por la especificidad disciplinar de la Ciencia Política, a partir de la revisión de (...) los métodos de investigación, en los programas de pregrado de las universidades de Bogotá. Para este efecto, está dividido en dos partes: primero, una revisión de la discusión epistemológica sobre los métodos de la disciplina en Francia e Inglaterra; y segundo, una revisión de los contenidos y la bibliografía de los syllabus de metodología de los programas de ciencias sociales de las universidades de Bogotá. Al final, se espera demostrar que no existen métodos específicos de Ciencia Política sino métodos genéricos para las ciencias sociales. (shrink)

The role of Greek thought in the final days of the Roman republic is a topic that has garnered much attention in recent years. This volume of essays, commissioned specially from a distinguished international group of scholars, explores the role and influence of Greek philosophy, specifically Epicureanism, in the late republic. It focuses primarily on the works and views of Cicero, premier politician and Roman philosopher of the day, and Lucretius, foremost among the representatives and supporters of Epicureanism at the (...) time. Throughout the volume, the impact of such disparate reception on the part of these leading authors is explored in a way that illuminates the popularity as well as the controversy attached to the followers of Epicurus in Italy, ranging from ethical and political concerns to the understanding of scientific and celestial phenomena.

RESUMEN Este articulo pretende describir el concepto de subjetividad nómade desarrollado por Rosi Braidotti, teniendo en cuenta su estructura con respecto a la diferencia sexual. Este análisis permite comprender cuál es la configuración del sujeto nómade revisando las implicaciones que tiene asociar tal concepto con la búsqueda de aceptación y representación de esa diferencia en el contexto político. La lectura critica de Braidotti remite directamente a examinar los conceptos originales de Deleuze y Guattari referidos al nomadismo, como singularización, devenir y (...) subjetivación. ABSTRACT This article aims to describe the concept of nomadic subjectivity developed by Rosi Braidotti, while considering its structure with respect to sexual difference. This analysis allows us to understand the configuration of the nomadic subject by reviewing the implications of associating the concept with the search for acceptance and representation of the sexual difference in the political context. A critical reading of Braidotti means to examine the Deleuze and Guattari's original concepts about nomadism, such as singularization, becoming and subjectivation. (shrink)

Background: Benzodiazepines have been widely used in clinical practice for over four decades and continue to be one of the most consumed and highly prescribed class of drugs available in the treatment of anxiety, depression, and insomnia. The literature indicates that Benzodiazepine users at a significantly increased risk of Motor Vehicle accidents compared to non-users but the impact on injuries at workplace is not well-defined. We aimed to investigate whether use of benzodiazepine is associated with increased risk of occupational injuries.Methods: (...) PubMed, Embase, and Scopus databases were searched. A meta-analysis was performed to calculate odds ratio and 95% confidence interval among case controls, cross-sectional studies, either questionnaire or laboratory exams based.Results: A total of 13 studies met inclusion criteria, involving 324,168 OI from seven different countries, with an estimated occurrence of benzodiazepine positivity of 2.71%. A total of 14 estimates were retrieved. Of them, 10 were based on laboratory analyses, three on institutional databases, while one study was based on questionnaires. Regarding the occupational groups, three estimates focused on commercial drivers, that exhibited a reduced risk ratio for benzodiazepine positivity compared to other occupational groups. Eventually, no increased risk for benzodiazepine positivity was identified, either from case control studies, or cross sectional studies, when only laboratory based estimates were taken in account.Conclusions: Even though benzodiazepines have the potential to increase injury rates among casual and chronic users, available evidence are insufficient to sustain this hypothesis, particularly when focusing on laboratory-based studies.
