Guidance and counseling in Latin America : General considerations about the criteria of coherence, cooperation and quality

Guidance in Latin America as a field of professional training, in comparison with Europe and United States , is an activity of recent acceptance in academic scene. The same has been characterized by a constant evolution in its eagerness to adapt to the new changes and social, political and economical transformations that occur in the Latin American continent. In this communication a general view appears about Guidance in this continent. The main considerations formulated are related to four dimensions: a) public policy dimension where the present situation and the proposals appear on the matter; b) the contextual dimension that makes reference to the counselor training and the different action settings; c) the organizational dimension that is related to the provision of this service, and d) the methodological dimension, where the main aspects related to the Guidance practice are developed.Facultad de Psicologí

Analco. Al otro lado de los desarrollos inmobiliarios

Partiendo de una metodología de investigación, se decidió hacer un análisis urbano muy profundo, tomando en cuenta todos los factores desde su ubicación, cómo se encuentra conectado en cuestión de transporte y movilidad, su infraestructura, el uso de suelo, su historia y todo el contexto patrimonial, la vegetación, asoleamientos y demás. Siguiendo de este planteamiento, se hizo un análisis más puntual de la zona donde se ubicó el predio o los predios con mejores características. Teniendo en cuenta todos los puntos anteriores, se hizo una investigación más detallada del predio final, con su análisis de colindancias, la vegetación de la zona, los cortes de calles, cuáles narrativas observamos en la zona y dentro del predio, cuáles eran los puntos clave a tomar en cuenta, cómo la circulación de las personas, la reintegración del espacio público, áreas verdes y naturales que acojan a los habitantes, el uso de espacios para comercio formal y ambulante integrando así todo el movimiento comercial que sucede en nuestra fachada norte y por último la propuesta de vivienda vertical incorporada con el contexto, surgiendo de todas las narrativas analizadas anteriormente, resultando así en la redensificación del barrio de Analco.ITESO, A.C

Estimating residence time distributions in industrial closed-circuit ball mills

This paper compares two deconvolution methodologies used to estimate residence time distributions (RTD) in industrial closed-circuit ball mills. Parametric and non-parametric deconvolution techniques were evaluated. Both techniques allowed for direct RTD estimates from inlet and outlet tracer measurements in the mills, with no need for mass balances nor assumptions to correct the effect of the tracer recirculation in the grinding circuits. Measurements of inlet and outlet concentrations were conducted by radioactive solid tracers and on-stream detectors. The parametric deconvolution was applied assuming the N-perfectly-mixed-reactors-in-series model, whereas the non-parametric deconvolution consisted of a constrained least squares estimation subject to non-negativity. The shapes of the estimated RTDs were consistent between these methodologies, showing mound-shaped distributions in all cases. From the parametric approach, mixing regimes described by 2–4 perfect mixers in series were observed, which indicated significant differences regarding perfect mixing. The mean (τmean) and median (τ50) residence times were more consistent with the RTD shapes when applying the parametric deconvolution. The non-parametric approach was more sensitive to noise, a disadvantage leading to mean residence times significantly higher than the median, and less consistent with the RTD locations. From the comparisons, the estimation strategies proved to be applicable in industrial closed-circuit ball mills. The parametric deconvolution led to better overall performances for τ50 = 1.7–8.3 min, given a suitable model structure for the RTDs

Predicting the outcome of patients with subarachnoid hemorrhage using machine learning techniques

Background: Outcome prediction for subarachnoid hemorrhage (SAH) helps guide care and compare global management strategies. Logistic regression models for outcome prediction may be cumbersome to apply in clinical practice. Objective: To use machine learning techniques to build a model of outcome prediction that makes the knowledge discovered from the data explicit and communicable to domain experts. Material and methods: A derivation cohort (n = 441) of nonselected SAH cases was analyzed using different classification algorithms to generate decision trees and decision rules. Algorithms used were C4.5, fast decision tree learner, partial decision trees, repeated incremental pruning to produce error reduction, nearest neighbor with generalization, and ripple down rule learner. Outcome was dichotomized in favorable [Glasgow outcome scale (GOS) = I–II] and poor (GOS = III–V). An independent cohort (n = 193) was used for validation. An exploratory questionnaire was given to potential users (specialist doctors) to gather their opinion on the classifier and its usability in clinical routine. Results: The best classifier was obtained with the C4.5 algorithm. It uses only two attributes [World Federation of Neurological Surgeons (WFNS) and Fisher’s scale] and leads to a simple decision tree. The accuracy of the classifier [area under the ROC curve (AUC) = 0.84; confidence interval (CI) = 0.80–0.88] is similar to that obtained by a logistic regression model (AUC = 0.86; CI = 0.83–0.89) derived from the same data and is considered better fit for clinical use.This work was supported in part by the Spanish Ministries of Science under Grant TRA2007-67374-C02-02 and Health under Grant FIS PI 070152.

Fabrication of hybrid graphene oxide/polyelectrolyte capsules by means of layer-by-layer assembly on erythrocyte cell templates

A novel and facile method was developed to produce hybrid graphene oxide (GO)–polyelectrolyte (PE) capsules using erythrocyte cells as templates. The capsules are easily produced through the layer-by-layer technique using alternating polyelectrolyte layers and GO sheets. The amount of GO and therefore its coverage in the resulting capsules can be tuned by adjusting the concentration of the GO dispersion during the assembly. The capsules retain the approximate shape and size of the erythrocyte template after the latter is totally removed by oxidation with NaOCl in water. The PE/GO capsules maintain their integrity and can be placed or located on other surfaces such as in a device. When the capsules are dried in air, they collapse to form a film that is approximately twice the thickness of the capsule membrane. AFM images in the present study suggest a film thickness of approx. 30 nm for the capsules in the collapsed state implying a thickness of approx. 15 nm for the layers in the collapsed capsule membrane. The polyelectrolytes used in the present study were polyallylamine hydrochloride (PAH) and polystyrenesulfonate sodium salt (PSS). Capsules where characterized by transmission electron microscopy (TEM), atomic force microscopy (AFM), dynamic light scattering (DLS) and Raman microscopy, the constituent layers by zeta potential and GO by TEM, XRD, and Raman and FTIR spectroscopies

The molecular basis and biologic significance of the β-dystroglycan-emerin interaction

β-dystroglycan (β-DG) assembles with lamins A/C and B1 and emerin at the nuclear envelope (NE) to maintain proper nuclear architecture and function. To provide insight into the nuclear function of β-DG, we characterized the interaction between β-DG and emerin at the molecular level. Emerin is a major NE protein that regulates multiple nuclear processes and whose deficiency results in Emery–Dreifuss muscular dystrophy (EDMD). Using truncated variants of β-DG and emerin, via a series of in vitro and in vivo binding experiments and a tailored computational analysis, we determined that the β-DG–emerin interaction is mediated at least in part by their respective transmembrane domains (TM). Using surface plasmon resonance assays we showed that emerin binds to β-DG with high affinity (KD in the nanomolar range). Remarkably, the analysis of cells in which DG was knocked out demonstrated that loss of β-DG resulted in a decreased emerin stability and impairment of emerin-mediated processes. β-DG and emerin are reciprocally required for their optimal targeting within the NE, as shown by immunofluorescence, western blotting and immunoprecipitation assays using emerin variants with mutations in the TM domain and B-lymphocytes of a patient with EDMD. In summary, we demonstrated that β-DG plays a role as an emerin interacting partner modulating its stability and function
