Amplitude and peculiar aspects of social inequalities in the French school
2005
05021http://www.scielo.br/pdf/ep/v31n1/a02v31n1.pdf; International audience; French sociology denounces vehemently since the end of the 1960s the important and standing social inequalities both in the access to the different levels of education and in school success stricto sensu. Such criticism has taken the form of a general theory put forward by Bourdieu and Passeron, in which such social inequalities are shown to be the necessary result of the functioning of the school institution. And this thesis, hugely influential not just among sociologists, but also more widely, has contributed to foster certain fatalism, since it establishes that the very function of school is to reproduce and leg…
Influence of the drawing process on the defect generation in multistep-index germanium-doped optical fibers
2009
International audience; Variation of germanium lone pair center (GLPC) concentration in germanosilicate multistep-index optical fibers and preforms was studied using confocal microscopy luminescence technique. The experimental results provide evidence that in the central core region ([Ge] ~11 wt. % ) of our specific canonical samples the ratio [GLPC]/[Ge] is five times larger in fiber than in preforms. The relative influence of the glass composition and of the drawing process on the generation efficiency of the GLPC defects that drive the glass photosensitivity is discussed. The radial distribution of these defects suggests a possible enhancement of the defect creation related to the intern…
The Latvian referendum on Russian as a second state language, February 2012
2016
On 18 February 2012 Latvian citizens participated in a referendum on making Russian a second official (“state”) language. The proposal was rejected by three-quarters of voters. There is a complex background to language policy in Latvia, where since regaining independence in 1991 the country has promoted Latvian as the only state language, though Russian and other languages are widely used at a societal level. The language law and associated citizenship law in Latvia (as in Estonia) have received considerable commentary, with recent significant writings disagreeing strongly regarding their interpretation. These laws have also very often been criticized by both European institutions and by Ru…

A Tool to Assess Architectural Education from the Sustainable Development Perspective and the Students' Viewpoint
2021
[EN] Architectural education plays a fundamental role in achieving sustainable development by training future professionals who can contribute to sustainability through their practice. Nevertheless, to ensure the introduction of sustainable development in the education of future architects, it is fundamental to understand what is being done and what could be improved. Despite this, a big gap has been detected in the assessment of architectural education in Spain and worldwide. Thus, a close-ended questionnaire for students has been designed based on the outcomes from a literature review, exploratory interviews with specialists, and the qualitative analysis of two schools of architecture. Ad…
De novo biosynthesis of simple aromatic compounds by an arthropod ( Archegozetes longisetosus )
2020
The ability to synthesize simple aromatic compounds is well known from bacteria, fungi and plants, which all share an exclusive biosynthetic route—the shikimic acid pathway. Some of these organisms further evolved the polyketide pathway to form core benzenoids via a head-to-tail condensation of polyketide precursors. Arthropods supposedly lack the ability to synthesize aromatics and instead rely on aromatic amino acids acquired from food, or from symbiotic microorganisms. The few studies purportedly showing de novo biosynthesis via the polyketide synthase (PKS) pathway failed to exclude endosymbiotic bacteria, so their results are inconclusive. We investigated the biosynthesis of aromatic …
Extracting locations from sport and exercise-related social media messages using a neural network-based bilingual toponym recognition model
2022
Funding: This study is a part of the “Equality in suburban physical activity environments, YLLI” research project (in Finnish: Yhdenvertainen liikunnallinen lähiö, YLLI). The project is being financed by the research program about suburban in Finland “Lähiöohjelma 2020-2022” coordinated by the Ministry of Environment (grant recipient: Dr. Petteri Muukkonen). Sport and exercise contribute to health and well-being in cities. While previous research has mainly focused on activities at specific locations such as sport facilities, “informal sport” that occur at arbitrary locations across the city have been largely neglected. Such activities are more challenging to observe, but this challenge may…
Colorimetric quantitation of trace amounts of sodium lauryl sulfate in the presence of nucleic acids and proteins
1992
A fast and sensitive procedure for the colorimetric detection of sodium lauryl sulfate (SDS) is presented. The assay is based upon the formation of a chloroform-extractable ion pair between lauryl sulfate and methylene blue that is quantified spectrophotometrically with an estimated detection limit of 150 ng of SDS. The method is suitable for the monitoring of contaminating traces of SDS in protein or nucleic acid samples that have the potential to interfere with enzymatic manipulations such as proteolytic digest, restriction analysis, or reverse transcription. Since the procedure is extremely simple and no special equipment is required it is accessible to every researcher concerned with SD…
Ģimenes ārstu un speciālistu nozīmēto H.pylori eradikācijas shēmu salīdzinājums; to atbilstība vadlīnijām un efektivitāte
2016
Helicobacter pylori kolonizē kuņģa gļotādu vairāk nekā pusei pasaules iedzīvotāju. Pasaules Veselības organizācija ir pasludinājusi H. pylori par 1. grupas kancerogēno vielu. Latvijā H. pylori eradikācijas shēmas nozīmē atbilstoši Māstrihtas IV vadlīnijām. Pētījuma mērķis – salīdzīnāt ģimenes ārstu un speciālistu nozīmēto H. pylori eradikācijas shēmu efektivitāti un atbilstību vadlīnijām. Pētījumā piedalījās 550 pacienti, kuri bija ieradušies uz eradikācijas efektivitātes testa veikšanu. Ģimenes ārsti vadlīnijām atbilstošas eradikācijas shēmas bija nozīmējuši 85,8% gadījumu, bet gastroenterologi – 96,8% gadījumu. Ģimenes ārsti efektīvu H. pylori eradikācijas terapiju nozīmējuši 77,6% gadīju…
H.pylori eradikācijas shēmas un to efektivitāte Latvijas ģimenes ārstu un gastroenterologu praksēs
2017
H. pylori ir kuņģī mītošs patogēns, kurš visiem inficētajiem izsauc aktīvu hronisku gastrītu. V Māstrihtas vadlīnijas nosaka, ka vajadzētu piedāvāt veikt H. pylori eradikāciju visiem pacientiem, lai novērstu risku nākotnē attīstīties nopietnākām komplikācijām, piemēram, kuņģa vēzim. Pētījumā analizētas Latvijas ģimenes ārstu un gastroenterologu nozīmētās eradikācijas terapijas. Iesaistīti 670 pacienti un kopumā izvērtētas 753 terapijas. Kopējā eradikācijas terapiju efektivitāte sasniedz tikai 73.31% un tā ir zemāka par vadlīnijās noteikto minimālo vēlamo efektivitātes rādītāju (80%). Gastroenterologi biežāk (85.14% gadījumu) kā ģimenes ārsti (70.96% gadījumu) nozīmē efektīvas eradikācijas t…
