Relación entre la inteligencia emocional y el ciberacoso en adolescentes

La inteligencia emocional es una capacidad que se relaciona negativamente con el acoso escolar en todas sus dimensiones. Asimismo, debido al desarrollo tecnológico de los últimos años, se originan nuevas formas de interacción en las que los adolescentes cuentan con mayor participación al hacer uso de las nuevas tecnologías. Con esto, el ciberacoso surge como una problemática que tiene un impacto negativo y mayor que el acoso tradicional. El objetivo de esta revisión es identificar la relación entre inteligencia emocional y el ciberacoso en los artículos científicos revisados que abordaron la relación entre ambas variables en población adolescentes. Se realizó una búsqueda sistemática siguiendo las indicaciones de la guía PRISMA (Urrútia y Bonfill, 2013). Las bases de datos consultadas fueron ProQuest, Scopus y EBSCO. Para el análisis se seleccionaron los estudios que evaluaron la inteligencia emocional y el ciberacoso (n = 7). En general, se discuten las relaciones encontradas en cuanto al enfoque teórico que aborda las variables, las pruebas utilizadas para medirlas, la evaluación de las dimensiones de ambos constructos y las limitaciones metodológicas evidenciadas.Emotional intelligence is a capacity that is negatively related to bullying in all its dimensions. Likewise, due to technological development in recent years, new forms of interaction have arisen in which adolescents have greater participation when making use of new technologies. With this, cyberbullying emerges as a problem that has a negative and greater impact than traditional bullying. The objective of this review is to identify the relationship between emotional intelligence and cyberbullying in the reviewed scientific articles that addressed the relationship between both variables in the adolescent population. A systematic search was carried out following the indications of the PRISMA guide (Urrútia and Bonfill, 2013). The databases consulted were ProQuest, Scopus and EBSCO. For the analysis, the studies that evaluated emotional intelligence and cyberbullying (n = 7) were selected. In general, the relationships found are discussed in terms of the theoretical approach that addresses the variables, the tests used to measure them, the evaluation of the dimensions of both constructs and the methodological limitations evidenced

Evaluación de dos complejos enzimaticos fibrolíticos comerciales sobre la digestibilidad y la cinética de digestión en el cogollo de caña de azucar (Saccharum officinarum)

El presente estudio tuvo como objetivo evaluar el efecto de dos complejos enzimáticos comerciales, sobre la digestibilidad in situ y la cinética de digestión de la materia seca del cogollo de caña de azúcar (Saccharum officinarum). El cogollo de caña de azúcar fue secado a 65 ºC por 48 h, molido con un tamiz de 3 mm y tratado 30 min antes de la incubación con las enzimas Allzyme Vegpro® (T1), y la enzima Rovabio Excel® (T2). Los complejos enzimáticos representaron el 1% respecto al sustrato. El sustrato sin ser tratado con enzimas fue considerado el tratamiento control (T0). El diseño experimental fue el de bloques al azar, con cuatro periodos, tres tratamientos (T0, T1 y T2) y dos repeticiones por periodo. Las muestras pesadas (1.8 g) fueron colocadas en bolsas de dacrón y vertidas al compartimiento 1 de la alpaca; luego de concluido el tiempo (6, 12, 24, 48, 72 y 96 horas) se retiraron, procediendo al lavado, secado y pesado. Los parámetros evaluados en cinética de digestión fueron: digestibilidad inicial, fracción degradable, tasa de degradación, digestión potencial y tiempo medio. Las variables fueron analizadas mediante análisis de varianza de dos vías y para la diferencia múltiple de medias se utilizó la prueba de Tukey. La digestibilidad in situ de la materia seca (DISMS) no mejoró en las distintas horas evaluadas, encontrándose solo pequeñas diferencias (p0.05) para la digestibilidad inicial, tasa de degradación, tiempo medio y la digestión potencial, solo se encontró diferencia (p<0.05) en la fracción degradable a favor de T1 versus T0 y T2. Se concluye que las enzimas fibrolíticas comerciales en la dosis utilizada no mejoran la digestibilidad ni la cinética de digestión del cogollo de caña de azúcar (Saccharum officinarum). Palabras clave: Enzima fibrolítica, cogollo de caña, digestibilidad in situ, alpaca.The objective of this study was to evaluate the in situ effect of two commercial enzymes on the digestibility and kinetics of the dry matter sugarcane bud (Saccharum officinarum). The sugarcane bud was dried at 65°C for 48 hours, ground with a 3 mm sieve, and incubated for 30 minutes with the Allzyme Vegpro ® enzymes (T1), and the Rovabio Excel ® enzyme (T2). The enzymes were used at 1% of the body weight. The substrate without treatment was considered the control treatment (T0). It was used a randomized experimental design, with four periods, three treatments (T0, T1 and T2), and two replicates for treatment period. The samples were weighing (1.8 g), imputed in dracon bags and placed alpaca 1 compartment. The bags were removed after digestion in different hours (6, 12, 24, 48, 72, and 96), proceeding to the wash and then drying and weighing. The parameters evaluated in digestion kinetics were: initial digestibility, degradable fraction, degradation rate, potential digestion and average time. The results were analyzed using two-way ANOVA and Tukey's test is used to mean multiple differences. This study showed that digestibility in situ dry matter (ISDMD) did not improve. It was found only small differences (p0.05) for initial digestibility, degradation rate, potential digestion and the average time, but there was difference (p<0.05) in the degradable fraction between T1 vs. T0 and T2. It is concluded that in the used dose fibrolytic enzymes do not increase digestibility or kinetics of digestion of the sugarcane bud (Saccharum officinarum). Key words: Enzyme fibrolytic, sugarcane bud, in situ digestibility, AlpacaTesi

Crítica del positivismo formalista en economía y las alternativas heterodoxas para la economía digital

Estudio crítico-hermenéutico e histórico-comparado de Principios de Economía Política, sobre la urgente necesidad revisora de fundamentos en la ciencia económica y su modelo ortodoxo de síntesis neoclásica, cada vez más formalista, pero menos realista. Dicho modelo confirmó su crisis con la Gran recesión de 2008 y su inadaptación para la economía digital, buscándose desde entonces alternativas, de ahí el recurso de los enfoques heterodoxos. Se compilan aquí las principales críticas, así como los riesgos y amenazas emergentes, si no se afronta el reto de repensar la economía y su digitalización para Horizonte 203

Functions and Characteristics of Music in Sound Fiction in the Case of RNE and Podium Podcast

The objective of this article is to know the importance of music whitin sound fiction on RTVE and Podium Podcast. With a mixed methodological approach, qualitative in terms of observation and interpretation of data and quantitative in terms of data collection, analysis, statistics and comparisons. The musical part is evaluated according to its internal function, external function, sound planes, musical, psychoacoustic and emotional resources. Our field of study focuses on two cases in particular with some characteristics that make them special, such as Guerra 3 (Podium Podcast) and In Cold Blood, Truman Capote from RNE, a live production proposal where the sound is released on site. The expected result of the study emphasizes the added value that music represents in sound fiction, as well as reviewing the temporal and introductory ellipses. The conclusions obtained confirm music as an added value.

The coupling of motion and conductive heating of a gas by localized energy sources

This paper investigates the time evolution of the near-isobaric flow field produced in a gas after the sudden application of a constant heat flux from a localized energy source. The problems of plane, line, and point heat sources are all investigated, with a power law for the temperature dependence of the thermal conductivity, after reduction to a quasi-linear heat equation for the temperature. In the planar and spherical cases, the constant heat flux defines scales for the length and time, which are used to nondimensionalize the problem. Numerical integration is used to provide the evolution of the temperature and velocity, and limiting solutions corresponding to small and large rescaled times are obtained. In the axisymmetric case, due to the absence of characteristic length and time scales, the solution is seen to admit a self-similar description in terms of the nondimensional heat flux. Profiles of temperature and radial velocity are provided for different values of this parameter, and the asymptotic limits of both small and large heating rates are addressed separately. The analysis reveals, in particular, the existence of front solutions when the resulting temperatures become much larger than the initial temperature, as occurs for sufficiently large times for the planar source, for sufficiently small times for the point source, and for sufficiently large heating rates for the line source

Acute adrenal insufficiency secondary to bilateral adrenal B-cell lymphoma: a case report and review of the literature

Primary adrenal lymphoma is an extremely rare entity which constitutes less than 1% of extranodal lymphomas. Most cases present with bilateral adrenal masses and without extraadrenal involvement, which can lead to symptoms of adrenal insufficiency. The prognosis is usually poor and chemotherapy is the first-line treatment option. We report here on a 78-year-old man admitted to our Internal Medicine Department because of constitutional symptoms and high fever spikes. He was diagnosed with adrenal insufficiency and a CT-scan revealed bilateral adrenal masses of about 6 cm in diameter. A percutaneous biopsy was performed and the histological exam was consistent with diffuse large B cell lymphoma. A review of the literature of this unusual entity was also carried out

Global Positioning System Analysis of Physical Demands in Elite Women’s Beach Handball Players in an Official Spanish Championship

This cross-sectional study aims to analyze the physical demands of elite beach handball players during an official competition. Nine elite female (mean age: 24.6 ± 4.0 years; body weight: 62.4 ± 4.6 kg; body height: 1.68 ± 0.059 m; training experience: 5 years; training: 6 h/week) beach handball players of the Spanish National Team were recruited for this study. A Global Positioning System was incorporated on each player’s back to analyze their movement patterns. Speed and distance were recorded at a sampling frequency of 15 Hz, whereas acceleration was recorded at 100 Hz by means of a built-in triaxial accelerometer. The main finding of the study is that 53% of the distance travelled is done at speeds between 1.5 and 5 km/h and 30% of the distance is between 9 and 13 km/h (83% of the total distance covered), which shows the intermittent efforts that beach handball involves at high intensity, as reflected in the analysis of the internal load with 62.82 ± 14.73% of the game time above 80% of the maximum heart rate. These data help to orientate training objectives to the physical demands required by the competition in order to optimize the players’ performance
