    Training and developing general labor competencies CLG in people is one of the great challenges that secondary educational institutions in Colombia must assume in order to contribute to the productive and social world according to the needs and particularities of each territory which requires a curricular structuring that relates the objectives proposed from the framework of education with territorial approaches in the search to contribute to the development of the local economy cultural socio-political perspectives in marked post-conflict scenarios and the comprehensive training of subjects who are prepared to respond to the changing demands of the present and future in diverse environments In this sense this article presents the results of data analysis under multivariate statistical analysis with R software supported in a systemic framework from the Vester matrix to understand the training processes focused on the development of CLG in the Municipality of San Vicente of Cagu n Caque

    Editorial: Judgment and decision making under uncertainty. Descriptive, normative, and prescriptive perspectives

    Get PDF
    Judgment and Decision Making Under Uncertainty: Descriptive, Normative, and Prescriptive Perspectives was motivated by our interest in better understanding why people judge and decide as they do (descriptive perspective), how they ideally ought to judge and decide (normative perspective), and how their judgment and decision-making processes might be improved in practice (prescriptive perspective). We sought papers that addressed some aspect of judgment and decision making from one or more of these three theoretical perspectives. We further sought contributions that examined judgment and decision making under conditions of uncertainty, which we intentionally left loosely defined. Our focus on uncertainty reflects the fact that the vast majority of decisions people make in life are not made under conditions of complete certainty, and the uncertainties may be more or less well-defined. Indeed, different components of a single judgment or decision may have multiple uncertainties associated with it, some of which may be fuzzier than others. Following our call for papers, we received 32 submissions, 17 of which were accepted. The latter set comprises this book. There are 11 original research articles, 2 hypothesis and theory articles, 2 perspectives, and 1 book review and systematic review each

    The present article shows the results from a qualitative research and thesis of the authors carried out on single-parent families with female heads of household in the city of Chillán (Chile). The general objective was to know the perception of the mothers from single-parent families in the previously mentioned city, about parentification as a tool to maintain family balance. Semi-structured interviews were held with these female heads of household and key informants,   which allowed an appreciation of role distribution within the household and also a greater understanding about how the parentification phenomenon can be a useful tool for each family system. The results showed how parentification follows the personal history of the household heads, as well as the environmental circumstances faced by the family or diseases of its members.En el presente artículo se exponen los resultados de una investigación de tipo cualitativa correspondiente a la actividad de tesis de los autores, realizada a familias monoparentales con jefatura femenina de la ciudad de Chillán (Chile), cuyo objetivo general fue conocer la percepción que tienen las madres de familias monoparentales de la mencionada ciudad, sobre la parentalización como medio para mantener el equilibrio familiar. Con dichas familias se trabajó mediante entrevistas semiestructuradas realizadas a las jefas de hogar e informantes clave, obteniéndose una apreciación de la distribución de los roles dentro del hogar y, de esta manera, una mayor comprensión de cómo el fenómeno de la parentalización logra ser una herramienta de utilidad para cada sistema familiar. Dentro de los resultados se puede apreciar como la parentalización responde a la historia personal de los jefes de hogar, así como a las circunstancias ambientales a las que se enfrentan las familias o enfermedades de los miembros de estas

    Properties of Submillimeter Galaxies in a Semi-analytic Model using the "Count Matching" Approach: Application to the ECDF-S

    Get PDF
    We present a new technique for modeling submillimeter galaxies (SMGs): the "Count Matching" approach. Using lightcones drawn from a semi-analytic model of galaxy formation, we choose physical galaxy properties given by the model as proxies for their submillimeter luminosities, assuming a monotonic relationship. As recent interferometric observations of the Extended Chandra Deep Field South show that the brightest sources detected by single-dish telescopes are comprised by emission from multiple fainter sources, we assign the submillimeter fluxes so that the combined LABOCA plus bright-end ALMA observed number counts for this field are reproduced. After turning the model catalogs given by the proxies into submillimeter maps, we perform a source extraction to include the effects of the observational process on the recovered counts and galaxy properties. We find that for all proxies, there are lines of sight giving counts consistent with those derived from LABOCA observations, even for input sources with randomized positions in the simulated map. Comparing the recovered redshift, stellar mass and host halo mass distributions for model SMGs with observational data, we find that the best among the proposed proxies is that in which the submillimeter luminosity increases monotonically with the product between dust mass and SFR. This proxy naturally reproduces a positive trend between SFR and bolometric IR luminosity. The majority of components of blended sources are spatially unassociated.Comment: 21 pages, 20 figures, 5 tables. Accepted for publication in MNRA

    An ALMA survey of submillimetre galaxies in the COSMOS field: The extent of the radio-emitting region revealed by 3 GHz imaging with the Very Large Array

    Get PDF
    We determine the radio size distribution of a large sample of 152 SMGs in COSMOS that were detected with ALMA at 1.3 mm. For this purpose, we used the observations taken by the VLA-COSMOS 3 GHz Large Project. One hundred and fifteen of the 152 target SMGs were found to have a 3 GHz counterpart. The median value of the major axis FWHM at 3 GHz is derived to be 4.6±0.44.6\pm0.4 kpc. The radio sizes show no evolutionary trend with redshift, or difference between different galaxy morphologies. We also derived the spectral indices between 1.4 and 3 GHz, and 3 GHz brightness temperatures for the sources, and the median values were found to be α=0.67\alpha=-0.67 and TB=12.6±2T_{\rm B}=12.6\pm2 K. Three of the target SMGs, which are also detected with the VLBA, show clearly higher brightness temperatures than the typical values. Although the observed radio emission appears to be predominantly powered by star formation and supernova activity, our results provide a strong indication of the presence of an AGN in the VLBA and X-ray-detected SMG AzTEC/C61. The median radio-emitting size we have derived is 1.5-3 times larger than the typical FIR dust-emitting sizes of SMGs, but similar to that of the SMGs' molecular gas component traced through mid-JJ line emission of CO. The physical conditions of SMGs probably render the diffusion of cosmic-ray electrons inefficient, and hence an unlikely process to lead to the observed extended radio sizes. Instead, our results point towards a scenario where SMGs are driven by galaxy interactions and mergers. Besides triggering vigorous starbursts, galaxy collisions can also pull out the magnetised fluids from the interacting disks, and give rise to a taffy-like synchrotron-emitting bridge. This provides an explanation for the spatially extended radio emission of SMGs, and can also cause a deviation from the well-known IR-radio correlation.Comment: 32 pages (incl. 5 appendices), 17 figures, 7 tables; accepted for publication in A&A; abstract abridged for arXi

      The objective of this article is to present the management of a patient diagnosed with a mandibular dentigerous cyst. The present case deals with a 14-year-old male patient, without relevant antecedents who attended the SERODU dental clinic, a radiolucent shadow between the dental pieces 42, 44 and 45 was included in the computerized axial tomography with the part piece No. 43 included in the symphysis of the mandibular region, horizontal position of the dental piece, the crown towards the distal and its root towards the medial with complete formation. At the crown level, a well-defined radiolucent shadow can be observed with a radiopaque halo, compatible with a dentigerous cyst. Therefore, it was decided to carry  out the endodontic treatment in the dental pieces 43,44,45, subsequently the enucleation of the lesion, elimination of the dental piece, curettage and rigid bone fixation were performed, to avoid pathological complications of adjacent structures such as fracture mandibular due to the size of the lesion. A histopathological diagnosis of dentigerous cyst was obtained. At the thirty-day control, a radiopaque area compatible with bone regeneration was observed radiographically, with a radiolucent halo separating with the original basal bone. Enucleation and rigid bone fixation is an effective treatment technique to eliminate the lesion that turned out to be benign.    El objetivo de este reporte es mostrar el manejo de un paciente con diagnóstico de quiste dentígero mandibular. Se  presenta el caso de un paciente de sexo masculino de 14 años de edad, sin antecedentes morbidos de importancia a la clínica odontológica SERODU, en la tomografía axial computarizada se evidenció una sombra radiolúcida entre las piezas dentales 42,44 y 45 con la pieza pieza Nº43  incluida en la sínfisis de la región mandibular, posición  horizontal de la  pieza dental, la corona hacia distal  y su raíz hacia medial con formación completa. A nivel de la corona se puede   observar una sombra radiolúcida bien definida con un halo radiopaco, compatible con un quiste dentígero. Por lo que se decidió llevar acabo el tratamiento endodóntico en las piezas dentales 43, 44,45, posteriormente se realizó la enucleación de la lesión, exéresis de la pieza dentaria, curetaje y fijación óseo rígida, para evitar complicaciones patológicas de  estructuras adyacentes como fractura mandibular por la dimensión de la lesión. Se obtuvo un diagnóstico histopatológico de quiste dentígero. Al control de treinta dias, se observó radiográficamente, una zona radiopaca compatible con regeneración ósea, con un halo radiolúcido de separación con el hueso basal original. La enucleación y la fijación ósea rígida, resultaron ser un tratamiento eficaz para eliminar dicha lesión que resultó ser benigna.
