Algunas consideraciones en torno a la Evaluación del Sistema Educativo y a lo que ésta comporta

1994

In this article we considere the reasons for evaluating the educational system. The quality of education is a preoccupation of the governments, specially in time of crisis and of educational reforms and this quality needs and evaluation of all the educational system. In Spain the National Institute of Quality and Evaluation has been recently created in order to carry out this evaluation. We reflect about the subject and also about the methods and the agents of this evaluation. We ask for a democratic and cooperative evaluation.

Cognitive behavioural therapy interventions for insomnia among shift workers: RCT in an occupational health setting

2019

Abstract Introduction The aim of the study was to compare the effectiveness of cognitive behavioural therapy interventions for insomnia (CBT-I) to that of a sleep hygiene intervention in a randomized controlled design among shift workers. We also studied whether the features of shift work disorder (SWD) affected the results. Methods A total of 83 shift workers with insomnia disorder were partially randomized into a group-based CBT-I, self-help CBT-I, or sleep hygiene control intervention. The outcomes were assessed before and after the interventions and at 6-month follow-up using questionnaires, a sleep diary, and actigraphy. Results Perceived severity of insomnia, sleep-related dysfunction…

Advanced performance monitoring for self-healing cellular mobile networks

2015

This dissertation is devoted to development and validation of advanced per- formance monitoring system for existing and future cellular mobile networks. Knowledge mining techniques are employed for analysis of user specific logs, collected with Minimization of Drive Tests (MDT) functionality. Ever increas- ing quality requirements, expansion of the mobile networks and their extend- ing heterogeneity, call for effective automatic means of performance monitoring. Nowadays, network operation is mostly controlled manually through aggregated key performance indicators and statistical profiles. These methods are are not able to fully address the dynamism and complexity of modern mobile networks. Se…

Dinamiskās olfaktometrijas alternatīvas monitoringa metodes aprobācija un testēšanas rezultātu analīze

2016

Smaku piesārņojums paliek aizvien aktuālāka vides problēma, kas vairumā gadījumu izriet no straujās rūpniecības un lauksaimniecības attīstības apdzīvoto vietu tuvumā. Tā kā smakas tieši ietekmē sabiedrības dzīves kvalitāti, to uzraudzībai tiek pievērsts aizvien vairāk uzmanības. Ņemot vērā subjektivitāti smaku uztverē, tiek meklēti risinājumi aizvien precīzākai smaku piesārņojuma līmeņa noteikšanai. Darba izstrādes ietvaros, tika aplūkotas divas smaku piesārņojuma noteikšanas metodes - dinamiskā olfaktometrija, kura ir plašāk pielietotā smakas koncentrācijas noteikšanas metode, kas nenodrošina nepārtrauktus smakas koncentrācijas mērījumus un raksturo smakas emisiju tikai parauga ņemšanas br…

Creating Office Spaces in the Mediterranean. The importance of well-being, health and performance of office users

2018

Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the exi…

Splines in convex sets under constraints of two‐sided inequality type in a hyperplane

2008

The problem of minimization of a smoothing functional under inequality constraints is considered in a hyperplane. The conditions of the existence of a solution are obtained and some properties of this solution are investigated. It is proved that the solution is a spline. The method for its construction is suggested. First Published Online: 14 Oct 2010

Antennal lobe representations are optimized when olfactory stimuli are periodically structured to simulate natural wing beat effects

2014

Animals use behaviors to actively sample the environment across a broad spectrum of sensory domains. These behaviors discretize the sensory experience into unique spatiotemporal moments, minimize sensory adaptation, and enhance perception. In olfaction, behaviors such as sniffing, antennal flicking, and wing beating all act to periodically expose olfactory epithelium. In mammals, it is thought that sniffing enhances neural representations; however, the effects of insect wing beating on representations remain unknown. To determine how well the antennal lobe produces odor-dependent representations when wing beating effects are simulated, we used extracellular methods to record neural units an…
