Live lecture screencast recording: a proposal to simplify the tasks associated with content production for video-teaching

Se trata de un resumen (Abstract) de la contribución. El acuerdo de transferencia de copyright del trabajo completo es incompatible con el depósito del mismo en RIUMA.Se describe la implementación inicial de un método simplificado de grabación en directo de sesiones de clase en asignaturas de las Escuelas de Ingeniería de la Universidad de Málaga. La simplificación se logra al incorporar en la actividad diaria del aula ciertas características típicas de la grabación en diferido de mini videos docentes. En una configuración mínima se graba únicamente el audio y el video en pantalla de la clase, evitando los desafíos técnicos y las dificultades que implica la grabación de otros elementos como la pizarra. Esto implica el uso de anotaciones en pantalla en tiempo real para reemplazar completamente las anotaciones en la pizarra.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech.

PopStar Evolutionary Synthesis Models II: Optical emission-line spectra from Giant H{\sc ii} regions

This is the second paper of a series reporting the results from the PopStar evolutionary synthesis models. Here we present synthetic emission line spectra of H{\sc ii} regions photoionized by young star clusters, for seven values of cluster masses and for ages between 0.1 and 5.2 Myr. The ionizing Spectral Energy Distributions (SEDs) are those obtained by the PopStar code \citep*{mgb09} for six different metallicities, with a very low metallicity set, Z=0.0001, not included in previous similar works. We assume that the radius of the H{\sc ii} region is the distance at which the ionized gas is deposited by the action of the mechanical energy of the winds and supernovae from the central ionizing young cluster. In this way the ionization parameter is eliminated as free argument, since now its value is obtained from the cluster physical properties (mass, age and metallicity) and from the gaseous medium characteristics (density and abundances). We discuss our results and compare them with those from previous models and also with a large and data set of giant H{\sc ii} regions for which abundances have been derived in a homogeneous manner. The values of the [OIII] lines (at $\lambda\lambda$ 4363, 4959, 5007\AA) in the lowest metallicity nebulae are found to be very weak and similar to those coming from very high metallicity regions (solar or over-solar). Thus, the sole use of the oxygen lines is not enough to distinguish between very low and very high metallicity regions. In these cases we emphasize the need of the additional support of alternative metallicity tracers, like the [SIII] lines in the near-\textit{IR}.Comment: 20 pages, 26 figures, accepted for publication in MNRAS Main Journa

Care coordination in two of Bogota’s public healthcare networks: A cross-sectional study among doctors

Introduction: Care coordination is a priority concern for healthcare systems. In Colombia, there is a lack of information on the topic. This study analysed how doctors of two Bogotá’s public healthcare networks perceived coordination between healthcare levels and what factors are associated with their perception. Methods: A cross-sectional study using the COORDENA-CO questionnaire to a sample of 363 doctors (network-1 = 181; network-2 = 182) in 2015. The questionnaire asks about types and dimensions of care coordination: information and clinical management, with items in a Likert scale, as well as conditions regarding health system, organisational and doctors’ conditions. Descriptive statistics and logistic regression analysis were performed. Results: The doctors’ perception of a high level of coordination did not exceed 25.4%. On coordination of information, limited transfer of clinical information was found. Concerning clinical management, there were limited care coherence, deficits in patient follow-up and lengthy waiting times for specialised care. A high perception of coordination were associated with being female, being over 50 years old, being a specialist, having less than one year’s working experience, working less than 20 h per week at the centre, forming part of network-1, having time available for performing coordination tasks, having job satisfaction and not identifying limitations imposed by healthcare insurers. Discussion: There was limited perception of coordination, in its different dimensions and types with some differences between networks. The results support the importance of guaranteeing job satisfaction, ensuring sufficient time to coordination-related activities and intervening in the restrictions imposed by healthcare insurers to improve care coordination. © The Author(s) 2019

Diagnostic tool for radical improvement in business processes

The present work presents a diagnostic tool applicable in any business sector; it works as a support to managers for decision-making towards the need for a radical improvement of processes. A literary review was conducted to collect case studies in order to identify the problems it addresses and the impacts generated by the process of reengineering application in organizations. Through conceptual modeling and synthesization, some diagnostic questions were formulated related to the problems that reengineering has addressed in the literature, and an evaluation model was built that allows organizations to identify what type of problem the organization has, its processes or departments, which should be approached from a radical improvement approach. Finally a diagnostic tool with an evaluation method was formulated, to recommend initiate process improvement either organization, departments o process, formulated fully integrable with PDCA cycle and evaluation or monitoring phases for systems like business activity monitoring based on IT systems, relevant in today's contexts when most of the nowadays organization are technology-based, and progressive improvements do not become a pragmatic and agile alternative in the business context

Perfil genético de la población de gatos (Felis catus) en Riohacha, la Guajira, mediante genes de pelaje

En el gato doméstico (Felis catus), la presencia de genes que codifican la coloración, el diseño y la longitud del pelaje, que se caracterizan por su herencia mendeliana y su fácil identificación fenotípica. Además su comportamiento reproductor no está controlado por el hombre, al igual que su vertiginoso incremento demográfico y su distribución casi mundial, ha convertido al gato doméstico, en una especie útil para la genética de poblaciones. El objetivo fue evaluar el perfil genético de las poblaciones de gatos domésticos (Felis catus) mediante genes del pelaje en Riohacha, La Guajira. Se efectuaron muestreos aleatorios de julio a septiembre del año 2015, en 267 animales adultos de seis barrios de Riohacha, utilizando marcadores de pelaje, cada animal se caracterizó fenotípicamente atendiendo a los marcadores de codificación morfológica: el locus ligado al sexo Orange (O) y los loci autosómicos Non-agouti (a), Tabby blotched (Tb), Dilution (d), Pelo largo (l) Manchado de blanco (S) y Dominante blanco (W). El marcador Non-agouti mostró la mayor frecuencia mientras los genes: Dominante blanco y pelo largo exhibió el valor más bajo. Se obtuvieron bajos valores de variabilidad genética a nivel global y poblacional. Así mismo, se obtuvo una escasa diferenciación genética entre poblaciones, acompañado de un elevado flujo génico; se observó exceso de heterocigotos a nivel poblacional y a nivel total y ausencia de equilibrio Hardy-Weinberg respecto a los marcadores Orange y Manchado de blanco. Se logró establecer que las poblaciones se encuentran muy relacionadas genéticamente

Fungal colonization with Pneumocystis correlates to increasing chloride channel accessory 1 (hCLCA1) suggesting a pathway for up-regulation of airway mucus responses, in infant lungs

AbstractFungal colonization with Pneumocystis is associated with increased airway mucus in infants during their primary Pneumocystis infection, and to severity of COPD in adults. The pathogenic mechanisms are under investigation. Interestingly, increased levels of hCLCA1 – a member of the calcium-sensitive chloride conductance family of proteins that drives mucus hypersecretion – have been associated with increased mucus production in patients diagnosed with COPD and in immunocompetent rodents with Pneumocystis infection. Pneumocystis is highly prevalent in infants; therefore, the contribution of Pneumocystis to hCLCA1 expression was examined in autopsied infant lungs. Respiratory viruses that may potentially increase mucus, were also examined. hCLCA1 expression was measured using actin-normalized Western-blot, and the burden of Pneumocystis organisms was quantified by qPCR in 55 autopsied lungs from apparently healthy infants who died in the community. Respiratory viruses were diagnosed using RT-PCR for RSV, metapneumovirus, influenza, and parainfluenza viruses; and by PCR for adenovirus. hCLCA1 levels in virus positive samples were comparable to those in virus-negative samples. An association between Pneumocystis and increased hCLCA1 expression was documented (P=0.028). Additionally, increasing Pneumocystis burden correlated with increasing hCLCA1 protein expression levels (P=0.017). Results strengthen the evidence of Pneumocystis-associated up-regulation of mucus-related airway responses in infant lungs. Further characterization of this immunocompetent host-Pneumocystis-interaction, including assessment of potential clinical significance, is warranted
