    La adolescencia es una etapa de turbulencias y cambios a nivel físico, socioafectivo y conductual, caracterizada por una elevada reactividad emocional al estrés y un aumento de las conductas exploratorias, lo cual favorece al desarrollo del individuo, perode forma desmedida puede derivar en problemas psicológicos. El objetivo de este trabajo ha sido evaluar los niveles de depresión, ansiedad, estrés y autoestima de una muestra de adolescentes estudiantes de educación privada, analizando las relaciones entre las variables y sus implicaciones sobre el rendimiento académico. Para ello, a través de una metodología no experimental de corte correlacional, se han analizado los datos de 141 alumnos/as de bachillerato. Se ha encontrado que los niveles de malestar emocional (depresión, ansiedad, estrés) están por encima de las puntuaciones normales (sujetos no clínicos), así como que existen diferencias significativas en función del sexo y relación con el rendimiento académico. Las características del tipo de centro, el alumnado, y la propia etapa evolutiva en la que se encuentran pueden explicar los resultados encontrados en el presente estudio, los cuales se describen más detalladamente en los apartados resultados y discusión. Por último, estos resultados indican la necesidad de trabajar estos aspectos en el ámbito educativo.Adolescence is a stage of turbulences as well as physical, socio-affective and behavioural changes. It is characterised by a high emotional responsiveness to stress and an increase of exploratory behaviours, which favours individual’s development, but can cause psychological problems if exceeded. The aim of this work is to evaluate the levels of depression, anxiety, stress and self-esteem in a group of teenagers, students of private education, to analyse the relations between the variables and their implications over the academic performance. For that, with a correlational and non-experimental methodology, the data of 141 students of bachillerato has been analysed. It should be noted that the level of emotional discomfort (depression, anxiety and stress) areabove the normal scoring (non-clinic people). In addition, there are significant differences depending on the genre and relation with the academic performance. The characteristics of the type of centre, the student body and the main evolutionary stage in which the teenagers are, can explain the results found in the present study. These are described in detail in the section “results and discussion”. Finally, these results show the need to work out these aspects in the academic world

    Soil Constraints (pH and Aluminium) for Legume Performance in Hill Country of Uruguay

    Get PDF
    Pastoral areas in eastern Uruguay have soils with pH 5.5 or lower (Mas, 1978), which is frequently associated with the acid soil syndrome (Cregan, 1980). As pH drops below 5.5, aluminium (Al) concentration can increase to toxic levels. These conditions may adversely affect growth of introduced legumes. A way to overcome these constraints is by the use of tolerant species. The objective of this study was to evaluate the adaptation and productivity of different legumes under environments with restrictions in pH and Al concentrations

    Effect of Different Phosphorous Sources and Levels on the Productive Behaviour of a \u3cem\u3eLotus Pedunculatus\u3c/em\u3e CV. Grasslands Maku Oversown Pasture

    Get PDF
    The organic meat production protocol of Uruguay (INAC, 2003) requires that the animals graze pastures that receive no chemical fertilisers. The oversown legume pastures in Uruguay used to be fertilised with soluble phosphorous (P) sources that are not accepted by the protocol. The relative efficiency of different P sources would be useful data for farmers. This information is not available for the acid soils of the eastern region of Uruguay. Lotus pedunculatus cv. Grasslands Maku is one of the most adapted legumes to be included in this type of pasture, as the sown area has increased in the last few years. The objective of this experiment was to evaluate the P levels response and the relative efficiency of different P fertilisers for forage production

    Parametric invariant Random Matrix Model and the emergence of multifractality

    Full text link
    We propose a random matrix modeling for the parametric evolution of eigenstates. The model is inspired by a large class of quantized chaotic systems. Its unique feature is having parametric invariance while still possessing the non-perturbative crossover that has been discussed by Wigner 50 years ago. Of particular interest is the emergence of an additional crossover to multifractality.Comment: 7 pages, 6 figures, expanded versio

    Key Health Issues Facing Latinas

    Acknowledging the relationship that exists among health outcomes, socioeconomic factors, and access to health care is key to understanding the health status of Latinas in Massachusetts. For example, poverty disproportionately affects Latinos in Massachusetts, and they have the lowest rate of health insurance in the Commonwealth despite the fact that Massachusetts has one of the most inclusive and comprehensive public health insurance programs in the nation. This situation impacts access to regular health care for Latinos and affects their overall health status. This fact sheet provides information on the following health areas of particular concern to Latinas: maternal and child health, sexually transmitted diseases, HIV/AIDS, breast cancer, cervical cancer, and diabetes

    From stem and progenitor cells to neurons in the developing neocortex: Key differences among hominids

    Get PDF
    Comparing the biology of humans to that of other primates, and notably other hominids, is a useful path to learn more about what makes us human. Some of the most interesting differences among hominids are closely related to brain development and function, for example behaviour and cognition. This makes it particularly interesting to compare the hominid neural cells of the neocortex, a part of the brain that plays central roles in those processes. However, well-preserved tissue from great apes is usually extremely difficult to obtain. A variety of new alternative tools, for example brain organoids, are now beginning to make it possible to search for such differences and analyse their potential biological and biomedical meaning. Here, we present an overview of recent findings from comparisons of the neural stem and progenitor cells (NSPCs) and neurons of hominids. In addition to differences in proliferation and differentiation of NSPCs, and maturation of neurons, we highlight that the regulation of the timing of these processes is emerging as a general foundational difference in the development of the neocortex of hominids

    Contributions to the Mathematical Technology Transfer with Finite Volume Methods

    [Abstract:] At the early 1980s, the research group in Mathematical Engineering, mat+i, started working on finite volume methods for the simulation of environmental issues concerning Galician rias (Spain). The focus was on the study of hyperbolic balance laws due to the presence of source terms related to the bathymetry. A correct treatment of these terms, an upwind discretization, was presented in [2, 7, 22]. The transfer of this knowledge has motivated the registration of the software Iber (http://www.iberaula.es). Latterly, under different research problems, we have been working on the development of a numerical algorithm for the resolution of Euler and Navier–Stokes equations. A hybrid projection finite volume/finite element method is employed making use of unstructured staggered grids (see [3, 9]). To attain second order of accuracy ADER methodology is employed [10]. On the other hand, with numerical simulation of gas transportation networks in view, a first-order well balanced finite volume scheme for the solution of a model, for the flow of a multicomponent gas in a pipe on non-flat topography, is introduced. The mathematical model consists of Euler equations, with source terms, coupled with the mass conservation equations of species. We propose a segregated scheme in which Euler and species equations are solved separately [6].The authors are indebted to E.F. Toro, from the Laboratory of Applied Mathematics, University of Trento, for the useful discussions on the subject.
