Mediācijas darbības izvērtējums ģimenes tiesību strīdos un tālākās attīstības iespējas.
2020
Viens no alternаtīvajiеm strīdu risināšanas mehānismiem, kas tikai nesen ir iegājis Latvijā ir mediācija, kuram, autores ieskatā ir pievēršama īpaša uzmanība, jo arī ārvalstīs tas ir ārkārtīgi izplatīts strīdu izšķiršanas vеids. Mediācija ir izmantojama ne tikai ģimenes, darba, komercstrīdos, nekustamā īpašuma, mantojuma strīdos, bet tāpat jebkurās strīdīgajās situācijās starp pusēm, kuras mērķis ir abpusēji izdevīga risinājuma panākšana. Mediācija pasaulē plaši tiek izmantota jau kopš pagājušā gadsimta 70.gadiem un ir atzīstama par strukturētu metodi. Mediācijas process ir īpaši nozīmīgs ģimenes strīdos, kur tiesāšanās var atstāt ietekmi ne tikai uz konkrēto pāri, bet arī viņu bērniem. Str…
Efficient Dense Disparity Map Reconstruction using Sparse Measurements
2018
International audience; In this paper, we propose a new stereo matching algorithm able to reconstruct efficiently a dense disparity maps from few sparse disparity measurements. The algorithm is initialized by sampling the reference image using the Simple Linear Iterative Clustering (SLIC) superpixel method. Then, a sparse disparity map is generated only for the obtained boundary pixels. The reconstruction of the entire disparity map is obtained through the scanline propagation method. Outliers were effectively removed using an adaptive vertical median filter. Experimental results were conducted on the standard and the new Middlebury datasets show that the proposed method produces high-quali…
Noise estimation from digital step-model signal
2013
International audience; This paper addresses the noise estimation in the digital domain and proposes a noise estimator based on the step signal model. It is efficient for any distribution of noise because it does not rely only on the smallest amplitudes in the signal or image. The proposed approach uses polarized/directional derivatives and a nonlinear combination of these derivatives to estimate the noise distribution (e.g., Gaussian, Poisson, speckle, etc.). The moments of this measured distribution can be computed and are also calculated theoretically on the basis of noise distribution models. The 1D performances are detailed, and as our work is mostly dedicated to image processing, a 2D…
La teneur hépatique en F4-Neuroprostanes : une variable prédictive majeure de la réduction de la plaque d’athérome
2012
Le fichier annexe contient le livre des résumés; Les propriétés athéroprotectrices des acides gras polyinsaturés de type n-3 à longue chaîne (AGPI n-3 LC), et en particulier de l’acide docosahexaénoique (DHA) ont été largement décrites. Néanmoins, les mécanismes d’action restent encore mal connus. Les recherches se sont récemment orientées vers l’identification des métabolites oxygénés issus des AGPI n-3 LC qui sont de plus en plus considérés comme des effecteurs majeurs de leurs effets athéroprotecteurs. Dans ce contexte, une étude dose-réponse de supplémentation en DHA a été réalisée chez un modèle animal d’athérosclérose (souris LDLR-/-) afin d’étudier les relations entre la progression …
Les premiers fers pendant l'âge du Bronze en France. Données nouvelles
2022
If iron was used in Asia Minor from the 3rd millennium BC, it was not known in Western Europe until the 13th century BC. In France, its first appears towards the end of the Bronze Age, possibly during the 13th century BC (Bronze final I / Bz D). Iron has been subsequently documented, especially during the 9th century BC (Bronze final IIIb / Late Atlantic Bronze Age 3 / Bz B2-3). Metallurgic iron is known only during this last stage of Late Bronze Age. The inventory of objects found in France, drawn up in 1981 and revised in 2009 has not changed much, despite several recent studies. However renewed data, with new discoveries and some objects removed from the list, call for an updated overvie…
Russian speakers’ media engagement and acculturation in Finland and Latvia
2022
AbstractThis comparative study looks into Russian speakers’ acculturation in Finland and Latvia by contrasting their cultural involvement and cultural preference Carlson and Güler (J Int Migr Integr 19:625–647, 2018. 10.1007/s12134-018-0554-4) with their self-reported news media use. Drawing on survey data collected from both countries (N = 224), the findings show that participants in both countries scored closer to biculturalism than monoculturalism. Majority of the respondents report predominantly engaging with non-Russian news media sources. However, regardless of the societal context, respondents who were more engaged with Russian news media sources also scored higher on cultural prefer…

Biochemical and toxigenic properties of Vibrio furnissii isolated from a European eel farm
1995
Abstract The present study describes for the first time the isolation of Vibrio furnissii strains from a European eel culture system which are pathogenic for eels ( Anguilla anguilla ) (LD 50 dose, 10 6 cfu/fish). Biochemical characterization of the isolates was performed by API 20E system and by classical numerical taxonomy. Growth at 4 °C, and with 6–8% (w/v) NaCl in a broth medium were necessary to differentiate Vibrio furnissii from Aeromonas species when the API 20E system was used. Virulence for eels of V. furnissii isolates was demonstrated by intraperitoneal injection of living cells. The extracellular products (ECPs) produced by V. furnissii were lethal to elvers and induced some o…
Fine adaptive control of precision grip without maximum pinch strength changes after median nerve mobilization
2020
ABSTRACTFine dexterity critically depends on information conveyed by the median nerve. While the effects of its compression and vibration are well characterized, little is known about longitudinal tension and excursion. Using a force-sensitive manipulandum, a numeric dynamometer and Semmes-Weinstein monofilaments, we examined the adaptations of precision grip control, maximum pinch strength and fingertips pressure sensation threshold before and immediately after the application of longitudinal tension and excursion mobilizations applied on the median nerve. Grip (GF) and load (LF) forces applied by the thumb, index and major fingers were collected in 40 healthy young participants during thr…
Intensity invariant nonlinear correlation filtering in spatially disjoint noise.
2010
We analyze the performance of a nonlinear correlation called the Locally Adaptive Contrast Invariant Filter in the presence of spatially disjoint noise under the peak-to-sidelobe ratio (PSR) metric. We show that the PSR using the nonlinear correlation improves as the disjoint noise intensity increases, whereas, for common linear filtering, it goes to zero. Experimental results as well as comparisons with a classical matched filter are given.
