EVALUACIÓN DE PLANES DE MEDIOS TELEVISIVOS: MODELO BETA BINOMIAL CON ESTIMACIÓN DE DUPLICACIÓN ENTRE E INTRA SOPORTE

This study puts forward a procedure for assessing the results of television advertising media plans. It innovates by requiring only information on audience figures for the television media, to determine the distribution of exposures generated by plans using multiple media vehicles and multiple insertions. The methodology consists of including in the beta binomial distribution the estimations of duplication of audience within and between media vehicles. The results show acceptable error levels in the estimation of the coverage and distribution of exposures for advertising campaigns in the medium of television. El presente trabajo plantea un procedimiento para evaluar los resultados de los planes publicitarios difundidos en el medio televisión. Presenta como novedad el requerir, únicamente, información de la audiencia de los soportes televisivos, para determinar la distribución de exposiciones generada por planes compuestos por múltiples soportes y múltiples inserciones. La metodología consiste en incluir en la distribución beta binomial las estimaciones de audiencia duplicada entre e intra soporte. Los resultados evidencian niveles de error aceptables en la estimación de la cobertura y distribución de exposiciones para las campañas publicitarias difundidas en el medio televisión.Publicidad, planificación de medios publicitarios; audiencia.

Diseño y validación de contenido de un cuestionario sobre la satisfacción, participación y opinión de mejora en las clases de educación física en secundaria

El objetivo del presente estudio fue diseñar un instrumento que mida de forma valida y fiable en alumnos de enseñanza secundaria obligatoria la satisfacción, participación y opinión de mejora en las clases de educación física. En primer lugar, se realizó una validación del contenido a través del acuerdo y consenso de nueve jueces expertos. En segundo lugar, se aplicó el cuestionario a una muestra de 38 sujetos, de 3º de la E.S.O., con edades entre 14.6 ± 0.8. Los datos iniciales aportaron modificaciones realizadas tanto por los jueces expertos como por los propios sujetos. Tras realizar las modificaciones, se obtuvieron adecuados valores de fiabilidad, mediante la consistencia interna (alfa=.825), como de validez de contenido (V de Aiken mínimo de 0.90)._____________________________The aim of this study was to design an instrument to measure a valid and reliable in compulsory secondary school students' satisfaction, participation and improvement in view of physical education classes. First, a content validation through consensus and agreement of nine judges. Secondly, the questionnaire was applied to a sample of 38 subjects, 3 º ESO, aged 14.6 ± 0.8. Initial data modifications made by the expert judges and by the subjects themselves. After making the changes, we obtained suitable values of reliability by internal consistency (alpha =. 825), and content validity (V Aiken minimum of 0.90)

Metaheuristic approaches for optimal broadcasting design in metropolitan MANETs

11th International Conference on Computer Aided Systems Theory. Las Palmas de Gran Canaria, Spain, February 12-16, 2007Mobile Ad-hoc Networks (MANETs) are composed of a set of communicating devices which are able to spontaneously interconnect without any pre-existing infrastructure. In such scenario, broadcasting becomes an operation of tremendous importance for the own existence and operation of the network. Optimizing a broadcasting strategy in MANETs is a multiobjective problem accounting for three goals: reaching as many stations as possible, minimizing the network utilization, and reducing the duration of the operation itself. This research, which has been developed within the OPLINK project (http://oplink.lcc.uma.es), faces a wide study about this problem in metropolitan MANETs with up to seven different advanced multiobjective metaheuristics. They all compute Pareto fronts of solutions which empower a human designer with the ability of choosing the preferred configuration for the network. The quality of these fronts is evaluated by using the hypervolume metric. The obtained results show that the SPEA2 algorithm is the most accurate metaheuristic for solving the broadcasting problem.Publicad

Pneumocystis jirovecii and microsporidia: An unusual coinfection in HIV patients?

Pneumocystis jirovecii and microsporidia species are recognized as opportunistic infectious pathogens in AIDS patients. Coinfection of both in one patient has been rarely reported. The aim of the present study was to investigate the coinfection of P. jirovecii and microsporidia in different tissues from AIDS deceased patients. Post mortem histological finding of P. jirovecii and microsporidia was demonstrated by means of the Grocott’smethenamine silver and Brown Brenn staining, respectively. Molecular technique was used for identification and characterization of both fungi. Out of the 514 autopsied cases P. jirovecii andmicrosporidia species were identified in 53 (10.3%) and 62 (12.1%) cases respectively. A total of five cases (0.97%) coinfected with Pneumocystis and microsporidia were recovered from all analyzed autopsies. Coinfection of Pneumocystis and microsporidia is very challenging and raises interesting issues about host-parasite relationship. The early diagnosis of both pathogens must be crucial to establish correct and early treatments, improve the patient’s evolution, reducing the risk of death

Characteristics of clinical trials of influenza and respiratory syncytial virus registered in ClinicalTrials.gov between 2014 and 2021

The randomized clinical trial (RCT) is the ideal and mandatory type of study to verify the effect and safety of a drug. Our aim is to examine the fundamental characteristics of interventional clinical trials on influenza and respiratory syncytial virus (RSV). This is a cross-sectional study of RCTs on influenza and RSV in humans between 2014 and 2021 registered in ClinicalTrials.gov. A total of 516 studies were identified: 94 for RSV, 423 for influenza, and 1 for both viruses. There were 51 RCTs of RSV vaccines (54.3%) and 344 (81.3%) for influenza virus vaccines (p < 0.001). Twelve (12.8%) RCTs for RSV were conducted only with women, and 6 were conducted only with pregnant women; for RCTs for influenza, 4 (0.9%) and 3, respectively. For RSV, 29 (31%) of the RCTs were exclusive to people under 5 years of age, and 21 (5%) for influenza virus (p < 0.001). For RSV, there are no RCTs exclusively for people older than or equal to 65 years and no phase 4 trials. RCTs on influenza virus and RSV has focused on vaccines. For the influenza virus, research has been consolidated, and for RSV, research is still in the development phase and directed at children and pregnant women
