Economic Aspects of the Microsoft Case: Networks, Interoperability and Competition
In this paper, we discuss the main economic aspects of the European Microsoft case; in particular, Microsoft’s refusal to supply the necessary information to make the competitors’ work group server systems interoperable with Windows Operating System. The case can be seen as an example of competition between networks. We review the relevant economics literature with the objective of understanding the motivations behind Microsoft’s strategies.Networks; Complementarities; Foreclosure; Interoperability; Antitrust
Is Emission Intensity or Output U-shaped in the Strictness of Environmental Policy
In a model where firms face a continuous choice of how much to invest in environmental innovation, we show that an ever stricter environmental policy does not always lead to ever cleaner production methods and ever lower production of polluting goods. It does so when the abatement technology is end-of-pipe. When the abatement technology is integrated however, either emission intensity or output is U-shaped in the strictness of policy. If the emission intensity is U-shaped, it will reach its lowest value at the point where the Marginal Abatement Cost curves intersect. These results hold with emission taxation (whether firms are price-takers or they interact strategically on the output market) as well as in the social optimum

Insights from Learning Analytics for Hands-On Cloud Computing Labs in AWS
Cloud computing instruction requires hands-on experience with a myriad of distributed computing services from a public cloud provider. Tracking the progress of the students, especially for online courses, requires one to automatically gather evidence and produce learning analytics in order to further determine the behavior and performance of students. With this aim, this paper describes the experience from an online course in cloud computing with Amazon Web Services on the creation of an open-source data processing tool to systematically obtain learning analytics related to the hands-on activities carried out throughout the course. These data, combined with the data obtained from the learning management system, have allowed the better characterization of the behavior of students in the course. Insights from a population of more than 420 online students through three academic years have been assessed, the dataset has been released for increased reproducibility. The results corroborate that course length has an impact on online students dropout. In addition, a gender analysis pointed out that there are no statistically significant differences in the final marks between genders, but women show an increased degree of commitment with the activities planned in the course
Repercusión emocional en el personal de enfermería pediátrica. Revisión
Repercusión emocional en el personal de enfermería pediátrica. Revisión Para el personal de enfermería pediátrica, trabajar con niños/as requiere cierta connotación psicológica y emocional. Gestionándose de manera negativa, puede ser causa de sentimientos de impotencia, incertidumbre, tristeza y excesiva vinculación emocional; en caso de hacerlo de manera positiva, se observa una atención integral al paciente y su familia. La falta de herramientas de afrontamiento efectivo ante situaciones extremas en los pacientes, como la muerte, es causa de un manejo no efectivo de la salud
The usefulness of Olanzapine plasma concentrations in monitoring treatment efficacy and metabolic disturbances in first-episode psychosis
Introduction: The role of Olanzapine therapeutic drug monitoring is controversial. The present study explores the associations of Olanzapine plasma concentrations with clinical response and metabolic side effects in first episode psychosis (FEP) after 2 months of treatment. Methods: Forty-seven patients were included. Improvement in clinical symptomatology was assessed using the PANSS. Metabolic assessment included weight, blood pressure, waist circumference, blood glucose, total cholesterol, high-density lipoprotein, low-density lipoprotein, and triglycerides. Results: The Olanzapine plasma concentrations after 2 months of treatment were positively correlated with weight gain (r = 0.49, p = 0.003), and a concentration > 23.28 ng/mL was identified as a positive predictor of weight gain (≥ 7%). The Olanzapine concentration to dose (C/D) ratio was positively correlated with the percentage of improvement in the total PANSS (r = 0.46, p = 0.004), and a C/D ratio > 2.12 was identified as a positive predictor of a good response (percentage of improvement > 30%) after 2 months of treatment. We also identified several factors that could alter Olanzapine pharmacokinetics: gender (p = 0.03), diagnosis (p = 0.05), smoking habit (p = 0.05), and co-medications such as valproic acid (p = 0.05) and anxiolytics (p = 0.01). Discussion: In conclusion, our results suggest that therapeutic drug monitoring of Olanzapine could be helpful to evaluate therapeutic efficacy and metabolic dysfunction in FEP patients treated with Olanzapine
Recopilación automatizada de evidencias de la realización de actividades educativas en el cloud
Resumen:
En este artículo se describe una innovación educativa
a través de dos experiencias docentes, para automatizar
la recopilación de evidencias generadas por
los alumnos durante la realización actividades educativas
sobre laboratorios computacionales. Estas han sido
implementadas en asignaturas del Máster de Computación
Paralela y Distribuida (MCPD) de la Universitat
Politècnica de València (UPV). Para ello se utiliza
la plataforma ODISEA, que permite desplegar y configurar
de forma dinámica Entornos Virtuales Computacionales
(EVCs) (laboratorios virtuales, simuladores,
herramientas software, etc.) necesarios para la puesta
en marcha y ejecución de las actividades educativas
sobre infraestructuras virtualizadas en un cloud, tanto
privado (on-premise) como público. Como resultado,
se presentan los mecanismos utilizados para la recopilación
automática de evidencias con el fin de realizar
un control de la gestión de abuso (uso excesivo)
de recursos por parte de los alumnos, y para la creación
de un portafolio digital. Además se detalla cómo
éstos han sido implementados en los EVCs requeridos
en cada actividad, siendo desplegados y configurados
automáticamente a través de la plataforma ODISEA.Abstract:
This paper describes an educational innovation driven
by two teaching experiences, to automatically gather
evidences of the activities of the students on computational
laboratories. These have been implemented
in various courses of the Master’s Degree in Parallel
and Distributed Computing (MCPD) at the Universitat
Politècnica de València (UPV). For that, we rely
on the ODISEA platform, which allows to dynamically
deploy and configure Computational Virtual Environments
(CVE) (such as virtual laboratories, simulators,
software tools, etc.) required to perform educational
activities on top of virtual infrastructures both
in public and private (on-premise) clouds. We present
the approaches carried out to automatically collect the
evidences, focusing on detecting abuse and misuse of
computational resources and the creation of a digital
portfolio. Furthermore, it is outlined how these mechanism
have been implemented in the CVEs required in
the activities using the capabilities provided by ODISEA
