Utopies et medias de masse
2019
International audience; Toute technologie est portée, au moins à ses débuts, par un imaginaire.Utopies et médias de masse traite des courants utopiques qui ont cherché à considérer les médias de masse comme un levier pour une société meilleure. La perspective adoptée est à la fois historique, sociétale et éducationnelle. Elle permet d’expliquer ces courants, de les situer dans leur contexte mais aussi de saisir l’influence qu’ils ont pu avoir. Si cet ouvrage jette parfois un regard rétrospectif sur le XIXe siècle ou plus loin dans le passé, il couvre principalement le XIXe siècle. Il examine également les conditions d’une éducation aux médias de masse au XXIe siècle.L’ouvrage s’adresse aux …
Economic Impact of 'Third-Wave' Cognitive Behavioral Therapies:A Systematic Review and Quality Assessment of Economic Evaluations in Randomized Contr…
2018
The term third-wave cognitive behavioral therapy (CBT) encompasses new forms of CBT that both extend and innovate within CBT. Most third-wave therapies have been subject to randomized controlled trials (RCTs) focused on clinical effectiveness; however, the number and quality of economic evaluations in these RCTs has been unknown and may be few. Evidence about efficiency of these therapies may help support decisions on efficient allocation of resources in health policies. The main aim of this study was to systematically review the economic impact of third-wave therapies in the treatment of patients with physical or mental conditions. We conducted a systematic literature search in PubMed, Psy…
Pacientu pieredze par profilaktiskajām apskatēm ģimenes ārsta praksē
2017
Pētniecības darbs: Pacientu pieredze par profilaktiskajām apskatēm ģimenes ārstu praksē. Tēmas aktualitāte: Bieži nopietnas saslimšanas sākuma stadijā norit bez būtiskiem simptomiem, kad parādās raksturīgie simptomi saslimšana jau ir ieilgusi, grūti padodas ārstēšanai vai ārstēšana ir novēlota. Savlaicīga saslimšanas atradne, palīdz vieglāk atgūt veselību un darbaspējas, ka arī ietaupīt materiālajā sfērā, uz slimības ārstēšanas izdevumu rēķina. Savlaicīgu saslimšanas diagnostiku mums palīdz noteikt profilaktiskās apskates, tāpēc ir svarīgi apmeklēt savu ģimenes ārstu un veikt profilaktiskās apskates katru gadu. Darba mērķis ir noskaidrot pacientu pieredzi par profilaktiskajām apskatēm ģimen…
Vēsturiskās pilsētas ainavas pieeja kultūras mantojuma saglabāšanai Kuldīgā
2015
Kuldīgas vēsturiskajā centrā kultūras mantojums sastopams visplašākajā tā izpratnē. Jau desmit gadu pašvaldība praktizē plānveidīgas kultūras mantojuma pārvaldības aktivitātes, kas pamanītas un atzinīgi novērtētas ne tikai Latvijā, bet arī starptautiski. Tomēr pilsētvide ir dzīva un mainīga, demonstrējot spēju tapt pielāgotai sabiedrības vajadzībām un kalpot tai. Arī kultūras mantojuma aizsardzībai un saglabāšanai tādai vajadzētu būt – visaptverošai, ar ilgtspējīgu vēsturiskās pilsētvides pārvaldību un integrētai vispārējā pilsētas attīstības ietvarā. Šī pētījuma mērķis ir izstrādāt priekšlikumus Kuldīgas kultūras mantojuma pārvaldības pilnveidošanai, balstoties teorētiskajās atziņās par vē…
Removing the saturation assumption in Bank-Weiser error estimator analysis in dimension three
2020
International audience; We provide a new argument proving the reliability of the Bank-Weiser estimator for Lagrange piecewise linear finite elements in both dimension two and three. The extension to dimension three constitutes the main novelty of our study. In addition, we present a numerical comparison of the Bank-Weiser and residual estimators for a three-dimensional test case.
Design and analysis of non-linear circuit with tunnel diode for hybrid control systems
2018
Electric circuits with tunnel diode's represent a classical example of dynamic systems with nonlinearities, which feature piecewise negative damping and multiple equilibria and, as consequence, nontrivial trajectories in the state-space. In this paper, we describe the experimental design and analysis of an electrical circuit, including a tunnel diode, allowing for a storage behavior with bistable output voltage states - low and high. The system is modeled for simulation and an experimental setup is designed and implemented in order to run a formal verification on different tools, applying a variety of hybrid control methods. The nonlinear diode's characteristic curve is experimentally deter…
Experimental investigation on different rainfall energy harvesting structures
2018
In this paper proposes an experimental comparison between different rainfall harvesting devices and the study of the corresponding electrical rectifying circuit. More in detail, three harvesting structures are considered: the cantilever, the bridge and the floating circle. For each of the proposed structure, different waveforms have been acquired and discussed. The processed data have been compared in order to suggest the best choice for the rectifying circuit, from the simplest one to the most endorsed in the technical literature.
Quantitative analysis of magnetization reversal in Ni thin films on unpoled and poled (0 1 1) [PbMg1/3Nb2/3O3]0.68–[PbTiO3]0.32piezoelectric substrat…
2016
The field angle dependence of the magnetization reversal in 20 nm thick polycrystalline Ni films grown on piezoelectric (0 1 1) [PbMg1/3Nb2/3O3](0.68)-[PbTiO3](0.32) (PMN-PT) substrates is analysed quantitatively to study the magnetic anisotropy induced in the film by poling the piezosubstrate. While the PMN-PT is in the unpoled state, the magnetization reversal is almost isotropic as expected from the polycrystalline nature of the film and corresponding to an orientation ratio (OR) of 1.2. The orientation ratio is obtained by fitting the angular dependence of normalized remanent magnetization to an adapted Stoner-Wohlfarth relation. Upon poling the piezosubstrate, a strong uniaxial anisotr…
Anomalies of dielectric properties and conductivity in single domain LiNbO3:Zn crystals
2016
ABSTRACTA study of the temperature dependence of dielectric constant, conductivity, and piezoelectric modulus in the single-domain state of LiNbO3 crystals modified by Zn admixture at threshold concentration is reported. Unipolarity of the LiNbO3:Zn crystals is observed to increase after treatment of brand-new samples by high-temperature electro-diffusion annealing and by subsequent high-temperature annealing of short-circuited samples. The observed effects are explained as a result of meta-stable residual domains collapsing at high temperature the collapse being assisted by disintegration of charged clusters stabilizing domain walls. The rise of unipolarity is accompanied by anomalies on t…
