VALIDACIóN EMPíRICA DEL MODELO DE FORMULACIóN CLíNICA POR PROCESOS BáSICOS DE CASTRO Y áNGEL

Acta Colombiana de Psicología , 2010,
Abstract: the aim of this research was to carry out the empirical validation of the clinical formulation model founded on basic processes and proposed by castro and angel (1998). a quasi-experimental trans-sectional descriptive and comparative design with three groups was used. participants were thirty psychologists assigned to the three groups according to their academic background and clinical experience (novice, intermediate an expert). they received written information about a clinical case in order to formulate it using castro and angel's model. validity indexes were obtained by calculating the percentage of agreements between the formulations of the three groups and a reference formulation; a special instrument was designed for this purpose. the statistical tests h of kruskal-wallis and w of kendall were also used. results showed that, in general, the model oriented the development of the formulations in the majority of aspects regardless the clinician's level of experience. this points out the empirical validity of the model; nevertheless, the levels of agreement were not high and the differences lie in one of the model's basic categories. this is the first study aimed at validating castro and angel's model; its results will allow the restructuring of that model and in turn will lay the foundations for validating it in future research projects.

Riesgo sistémico y estabilidad del sistema de pagos de alto valor en Colombia: análisis bajo topología de redes y simulación de pagos
Machado,Clara; León,Carlos; Sarmiento,Miguel; Cepeda,Freddy; Chipatecua,Orlando; Cely,Jorge;
Ensayos sobre POLíTICA ECONóMICA , 2011,
Abstract: this article studies the stability of the high value payment system (ps) in colombia (deposit account system) when faced with noncompliance on the part of a systemically important entity and evaluates the response capacity of the affected entities on the basis of the utilization of their resources, as well as through the liquidity mechanisms provided by the banco de la república (the central bank of colombia). according to the recent literature, systemically important entities are grouped under the term too-connected-to-fail (tctf) in relation to different scenarios involving colombian treasury bonds (tes) and ps activities. ps stability is evaluated by means of network topology (nt) and a simulation model of payments (smp), which incorporate a resolution algorithm recursive queue of the first in first out (fifo) kind and a multilateral compensation algorithm.
Actualización en Aspergilosis con énfasis en Aspergilosis invasora

Abstract: the genus aspergillus is ubiquitous in nature and has universal distribution; for this reason contact with this fungus includes immunocompetent and non-immunocompetent hosts. the most common form of acquiring this fungus is through air, and its clinical manifestations and topographic location correspond to the interaction of the fungus and its host's immune capacity. the main clinical manifestation of this fungus is a breathing condition and has a very significant impact on mortality and morbidity, especially in non-immunocompetent patients. patients with haematological malignancies, heart or lung transplant surgeries, and aids are the most susceptible to present tissue and vascular invasion by this fungus in the form of invasive aspergillosis (ia). the ia presents diagnostic difficulties in non-immunocompetent hosts; therefore using non-invasive diagnosis methods for this group of patients offers therapeutic approach guidance. antifungal drugs such as azoles (voriconazole) and echinocandins (caspofungin), that have improved the ai group results, are available nowadays. this article updates the literature on ai diagnosis and treatment.

Abstract: El género Aspergillus es ubicuo en la naturaleza y de distribución universal. Por esta razón, el contacto con este hongo incluye hospederos inmunocompetentes e inmunosuprimidos. La vía aérea es la forma más frecuente de adquirir este hongo y sus manifestaciones clínicas y localización topográfica se relacionan con la interacción del hongo y la capacidad inmunológica del hospedero. La principal manifestación clínica de este hongo es a nivel respiratorio, con un impacto muy importante en mortalidad y morbilidad, especialmente en el paciente inmunosuprimido. Los pacientes con tumores hematológicos, trasplantes de corazón, pulmón y con sida son más susceptibles de presentar invasión tisular y vascular por este hongo, que en tales casos se manifiesta como Aspergilosis Invasora (AI). La AI ofrece dificultades diagnósticas en el hospedero inmunosuprimido por lo que en este grupo de pacientes el uso de métodos de diagnóstico no invasores permite guiar el abordaje terapéutico. En la actualidad se dispone de medicamentos antifúngicos del grupo de los azoles (voriconazol) y de las equinocandinas (caspofungina) que han mejorado el resultado de la AI. En este artículo se actualiza la literatura en cuanto al diagnóstico y tratamiento de la AI.

“Fear” Is a Book of Fiction Mixed with Real Events  [PDF]
Freddy A. Paniagua
Open Journal of Political Science (OJPS) , 2019, DOI: 10.4236/ojps.2019.91006
Abstract: Several book reviews were published prior to the publication of “Fear: Trump in the White House” on September 11, 2018, with emphasis on “terrifying scenes” (e.g., John F, Kelly reportedly said that Trump is an “idiot”). These reviews, however, did not discuss two major problems in “Fear,” namely, the contexts (i.e., environments, locations, settings, etc.) in which dialogues in “Fear” occurred and the probability that Woodward’s “sources” were present in such contexts, as well as the probability that such “sources” remembered and then reported verbatim extensive dialogues between two or more individuals in “Fear,” because of the limited capacity of the human short-term memory. This commentary suggests that Woodward did not “fabricate” the contents of “Fear,” as claimed by some in the White House, but argues that Woodward honestly believed what his “sources” reported to him without questioning such “sources” regarding the two major problems in “Fear.”
Fuzzy classification of phantom parent groups in an animal model

Genetics Selection Evolution , 2009, DOI: 10.1186/1297-9686-41-42
Abstract: To avoid the downside of such distinct classification, a fuzzy logic approach is suggested. A phantom parent can be assigned to several genetic groups, with proportions between zero and one that sum to one. Rules were presented for assigning coefficients to the inverse of the relationship matrix for fuzzy-classified genetic groups. This approach was illustrated with simulated data from ten generations of mass selection. Observations and pedigree records were randomly deleted. Phantom parent groups were defined on the basis of gender and generation number. In one scenario, uncertainty about generation of birth was simulated for some animals with unknown parents. In the distinct classification, one of the two possible generations of birth was randomly chosen to assign phantom parents to genetic groups for animals with simulated uncertainty, whereas the phantom parents were assigned to both possible genetic groups in the fuzzy classification.The empirical prediction error variance (PEV) was somewhat lower for fuzzy-classified genetic groups. The ranking of animals with unknown parents was more correct and less variable across replicates in comparison with distinct genetic groups. In another scenario, each phantom parent was assigned to three groups, one pertaining to its gender, and two pertaining to the first and last generation, with proportion depending on the (true) generation of birth. Due to the lower number of groups, the empirical PEV of breeding values was smaller when genetic groups were fuzzy-classified.Fuzzy-classification provides the potential to describe the genetic level of unknown parents in a more parsimonious and structured manner, and thereby increases the precision of predicted breeding values.Historically, genetic groups have been included in genetic evaluation models to account for selection not described by known genetic relationships. Introduction of animal models, which makes is possible to account for known relationships in the genetic evalua
