Implicações do clima organizacional na qualidade dos serviços públicos autárquicos segundo o modelo da estrutura comum de avaliação: estudo do caso de uma câmara municipal portuguesa

O presente trabalho pretende, partindo-se de algumas das componentes do Modelo da Estrutura Comum de Avaliação (Common Assessement Framework), analisar a influência que a liderança - como meio do referido modelo - terá em alguns dos factores que constituem o clima organizacional e daí extrair qual o impacto destes na qualidade dos serviços públicos autárquicos, através dos resultados relativos às pessoas - resultado do mesmo modelo. Para efeitos do presente trabalho serão considerados dois dos sistemas de liderança de Likert (autocrático-coercivo e participativo), bem como alguns dos factores do clima organizacional (motivação, satisfação, empowerment, conflito e stress).The present work pretends, by starting with some of the components of the Common Assessement Framework Model, to analyse the influence that leadership – as agent of the refered model – have in some of the organizational climate factors and then know what is the impact of such factors in the quality of the public services of the local authorities (city councils) throw the results of the persons - result of the same model. For that we used two of the leardership systems of Likert [authoritarian (autocratic) and participative (democratic)] and some of the organizational climate factors (motivation, satisfaction, empowerment, conflict and stress)

Caracterización de la intención emprendedora en estudiantes universitarios a partir del Modelo de Intención Emprendedora Sistémico: caso de estudio

[EN] This paper presents a characterization of the entrepreneurial intention of university students in the city of Medellin. It is based on a quantitative methodological design from a self-administered questionnaire that was applied and validated to 879 students. This questionnaire collected data about the main factors reported in the Systemic Entrepreneurship Intention Model. Factors or components that describe behavior patterns when undertaking a new company were identified through a principal component and cluster analysis. The results identify two factors that explain most of the data variance: the first one is the perceived viability by students to carry out processes of new companies, and the second one is the convenience factor that brings the creation a company. Furthermore, three groups or clusters of students with common characteristics in their entrepreneurial intention were identified. First, the “entrepreneurs” are characterized by having a positive attitude and aptitude regarding entrepreneurship. The second group is “neutral” and they are subjects partially affected or indifferent about wanting to start a new company. Finally, the group of “non-entrepreneurs” is composed of individuals who showed behavior of apathy towards entrepreneurship.[ES] Este artículo muestra una caracterización de la intención emprendedora de estudiantes universitarios de la ciudad de Medellín. Este estudio parte de un diseño metodológico cuantitativo a partir de un cuestionario autoadministrado aplicado y validado a 879 estudiantes, en el cual se recolectó información sobre los principales factores reportados en el Modelo de Intención Emprendedora Sistémico. Mediante un análisis de componentes principales y de clúster se lograron identificar los factores o componentes que describen los patrones de comportamiento en cuanto a emprender una empresa. Los resultados obtenidos identifican dos factores que explican la mayor parte de la varianza de los datos, el primero es la viabilidad percibida por los estudiantes para llevar a cabo procesos de emprendimiento y el segundo factor es la conveniencia que le reporta el crear una empresa. De otro lado, se lograron identificar tres grupos o clúster de estudiantes con características comunes y disímiles en su intención de emprender, el primero, los “emprendedores”, que se caracterizan por poseer una actitud y aptitud positiva frente al tema; el segundo grupo el “neutro” el cual está parcialmente afectado o indiferente en cuanto a querer emprender una nueva empresa y el último los “no emprendedores”, los cuales presentaron un comportamiento de apatía frente al tema

Using the Didactical Suitability Criteria tool when assessing mathematics learning sequences

En este artículo se utiliza la herramienta de análisis didáctico denominada Criterios de Idoneidad Didáctica (CID) para valorar las secuencias didácticas elaboradas por maestros que han cursado un Diplomado en la Universidad de Panamá. Dicha herramienta se ha desarrollado en el marco del Enfoque Ontosemiótico (EOS), revelándose útil para este tipo de acciones, tal como lo han validado las investigaciones previas. En esta investigación se propone un uso sistemático de los CID, aplicando una escala ordinal (tipo Likert) de cuatro posiciones, para cuantificar cada uno de los criterios y, así, evaluar las secuencias didácticas. Los investigadores (uno de los cuales es el formador de los docentes) discuten las secuencias didácticas elaboradas por los docentes, a partir de las grabaciones de aula, donde el análisis les permite sacar conclusiones sobre las decisiones didácticas que realizan los maestros. El uso de los CID revela fortalezas y debilidades en las secuencias didácticas de los maestros. El análisis de la idoneidad didáctica de las secuencias didácticas presentadas por los y las maestras sugiere que el Diplomado ha servido para mejorar su competencia de análisis didáctico, aunque también se han encontrado evidencias que sugieren que la experiencia previa docente aporta elementos importantes que explican el mayor uso de algunos criterios para orientar su práctica

Partial Genetic Turnover in Neandertals: Continuity in the East and Population Replacement in the West

Remarkably little is known about the population-level processes leading up to the extinction of the neandertal. To examine this, we use mitochondrial DNA sequences from 13 neandertal individuals, including a novel sequence from northern Spain, to examine neandertal demographic history. Our analyses indicate that recent western European neandertals (48 kyr) European neandertals. Using control region sequences, Bayesian demographic simulations provide higher support for a model of population fragmentation followed by separate demographic trajectories in subpopulations over a null model of a single stable population. The most parsimonious explanation for these results is that of a population turnover in western Europe during early Marine Isotope Stage 3, predating the arrival of anatomically modern humans in the region

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Mammalian Stem Cells Reprogramming in Response to Terahertz Radiation

We report that extended exposure to broad-spectrum terahertz radiation results in specific changes in cellular functions that are closely related to DNA-directed gene transcription. Our gene chip survey of gene expression shows that whereas 89% of the protein coding genes in mouse stem cells do not respond to the applied terahertz radiation, certain genes are activated, while other are repressed. RT-PCR experiments with selected gene probes corresponding to transcripts in the three groups of genes detail the gene specific effect. The response was not only gene specific but also irradiation conditions dependent. Our findings suggest that the applied terahertz irradiation accelerates cell differentiation toward adipose phenotype by activating the transcription factor peroxisome proliferator-activated receptor gamma (PPARG). Finally, our molecular dynamics computer simulations indicate that the local breathing dynamics of the PPARG promoter DNA coincides with the gene specific response to the THz radiation. We propose that THz radiation is a potential tool for cellular reprogramming

Relativismo y racionalidad

¿Qué quiere decir que el hombre es un ser racional? ¿Hay una o muchas racionalidades? ¿Son los límites de lo que podemos decir sobre la realidad también los límites de la realidad? ¿Es la percepción de algo real la garantía de que todos percibimos lo mismo? ¿Son la explicación y la compresión formas de justificación dependientes de contextos culturales, de la escogencia más o menos convencional de modelos de explicación, o de estructuras de comprensión universal? ¿Hay una verdad y una realidad en la matemática con independencia de nuestras formas de razonar, relacionadas de algún modo con nuestras formas de vida?. / Contenido.

Prospective individual patient data meta-analysis of two randomized trials on convalescent plasma for COVID-19 outpatients

Data on convalescent plasma (CP) treatment in COVID-19 outpatients are scarce. We aimed to assess whether CP administered during the first week of symptoms reduced the disease progression or risk of hospitalization of outpatients. Two multicenter, double-blind randomized trials (NCT04621123, NCT04589949) were merged with data pooling starting when = 50 years and symptomatic for <= 7days were included. The intervention consisted of 200-300mL of CP with a predefined minimum level of antibodies. Primary endpoints were a 5-point disease severity scale and a composite of hospitalization or death by 28 days. Amongst the 797 patients included, 390 received CP and 392 placebo; they had a median age of 58 years, 1 comorbidity, 5 days symptoms and 93% had negative IgG antibody-test. Seventy-four patients were hospitalized, 6 required mechanical ventilation and 3 died. The odds ratio (OR) of CP for improved disease severity scale was 0.936 (credible interval (CI) 0.667-1.311); OR for hospitalization or death was 0.919 (CI 0.592-1.416). CP effect on hospital admission or death was largest in patients with <= 5 days of symptoms (OR 0.658, 95%CI 0.394-1.085). CP did not decrease the time to full symptom resolution

Combined measurement of differential and total cross sections in the H → γγ and the H → ZZ* → 4ℓ decay channels at s=13 TeV with the ATLAS detector

A combined measurement of differential and inclusive total cross sections of Higgs boson production is performed using 36.1 fb−1 of 13 TeV proton–proton collision data produced by the LHC and recorded by the ATLAS detector in 2015 and 2016. Cross sections are obtained from measured H→γγ and H→ZZ*(→4ℓ event yields, which are combined taking into account detector efficiencies, resolution, acceptances and branching fractions. The total Higgs boson production cross section is measured to be 57.0−5.9 +6.0 (stat.) −3.3 +4.0 (syst.) pb, in agreement with the Standard Model prediction. Differential cross-section measurements are presented for the Higgs boson transverse momentum distribution, Higgs boson rapidity, number of jets produced together with the Higgs boson, and the transverse momentum of the leading jet. The results from the two decay channels are found to be compatible, and their combination agrees with the Standard Model predictions
