"Yes we can" or "Make America great again" : comparison of representations in Barack Obama and Donald Trump's inaugural addresses
2017
Kielellä ja kielenkäyttötavoilla, diskursseilla, on suuria vaikutuksia ihmisten asenteisiin, toimintatapoihin ja tapaan nähdä maailma. Erityisesti poliittiset diskurssit ovat merkittävä tutkimuksen kohde, sillä ne saavuttavat usein suuren yleisön. Koska poliitikoilla on näkyvä rooli yhteiskunnassa, on tärkeää tutkia, millaisia asenteita, ideologioita ja arvoja he levittävät puheidensa välityksellä. Tätä teemaa voidaan tarkastella hyödyntäen kriittistä diskurssianalyysia, jonka avulla usein tarkastellaan eriarvoisuutta ja vallan väärinkäyttöä. Tämän tutkielman tarkoituksena oli selvittää, millaisia representaatioita Barack Obama ja Donald Trump loivat eri ihmisryhmistä virkaanastujaispuheiss…
L’organisation des circuits courts par les intermédiaires.
2016
The dissertation deals with the institutionalisation of proximity in agri-food markets and the place occupied in this process by non-economic intermediaries (employees of associations, researchers, members of staff from the ministry of Agriculture, advisers of the chambers of agriculture). By varying the scales of investigation, from the national to the departmental level, and by articulating qualitative and quantitative methods, this work points out the paradox that constitute the development of those intermediary agents, as proximity is progressively defined and objectified as a virtuous component of the merchant relationship. On the basis of a sociology of merchant institutions attentive…
Lojalitātes princips Latvijas valsts civildienestā
2017
Bakalaura darba (“Lojalitātes princips Latvijas valsts civildienestā”) mērķis ir izskaidrot lojalitātes principa saturu Latvijas Republikas Valsts civildienesta likuma izpratnē, atrast lojalitātes principa novērtēšanas kritērijus. Darba uzdevums ir analizēt lojalitātes principa būtību Latvijas un ārvalstu likumos, lai pēc nepieciešamības konstatētu Valsts civildienesta likuma spēkā esošās redakcijas trūkumus. Darba rezultātā izmantojot salīdzinošo analīzi tika secināts, ka lojalitātes principa saturs Valsts civildienesta likumā, kā arī citos likumos, nav pietiekami detalizēts, līdz ar to pienākums būt uzticīgam valstij un Satversmei ir nepieciešams noregulēt precīzāk.
Experimental and theoretical studies on corals. I. Toward understanding the origin of color in precious red corals from Raman and IR spectroscopies a…
2010
An attempt to explain the origin of the vivid red color in precious pink and red corals was undertaken. Raman and IR spectroscopies were applied to characterize white, pink and red corals. The position of the Raman signal near 1500 cm−1 of some corals and pearls was associated by several authors with the presence of the mixture of all‐trans‐polyenic pigments, containing 6–16 conjugated CC bonds or β‐carotenoids. This hypothesis was examined theoretically by performing extensive B3LYP‐DFT calculations of vibrational spectra of the model polyenic compounds. The B3LYP/6‐311++G** predicted positions of the dominating Raman mode depend on the number of CC units (Cn parameter) and can be accura…
Modeling red coral (Corallium rubrum) and African snail (Helixia aspersa) shell pigments: Raman spectroscopy versus DFT studies
2016
Pigments from red coral (Corallium rubrum) and African snail (Helixia aspersa) shell were studied non-invasively using Raman spectroscopy with 1064-nm laser beam. The two observed bands because of organic pigments confined in biomineralized CaCO3 matrix at about 1500 and 1100 cm−1 were assigned to ν(C[DOUBLE BOND]C) and ν(C―C), respectively. Both signals originate from polyene(s) of largely unknown structure, containing several conjugated C[DOUBLE BOND]C bonds. The small peak at 1016 cm−1 in the Raman spectrum of coral pigment was assigned to in-plane ―CH3 rocking or structural deformation of polyene chain because of spatial confinement in the mineral matrix. The organic pigments in red cor…
Raman Investigations to Identify Corallium rubrum in Iron Age Jewelry and Ornaments
2016
International audience; During the Central European Iron Age, more specifically between 600 and 100 BC, red precious corals (Corallium rubrum) became very popular in many regions, often associated with the so-called (early) Celts. Red corals are ideally suited to investigate several key questions of Iron Age research, like trade patterns or social and economic structures. While it is fairly easy to distinguish modern C. rubrum from bone, ivory or shells, archaeologists are confronted with ancient, hence altered, artifacts. Due to ageing processes, archaeological corals lose their intensive red color and shiny surface and can easily be confused with these other light colored materials. We pr…
Low-temperature single crystal X-ray diffraction and high-pressure Raman studies on [(CH3)2NH2]2[SbCl5]
2007
The structure of bis(dimethylammonium) pentachloroantimonate(III), [(CH{sub 3}){sub 2}NH{sub 2}]{sub 2}[SbCl{sub 5}], BDP, was studied at 15 K and ambient pressure by single-crystal X-ray diffraction as well as at ambient temperature and high pressures up to 4.87(5) GPa by Raman spectroscopy. BDP crystallizes in the orthorhombic Pnma space group with a=8.4069(4), b=11.7973(7), c=14.8496(7) A, and Z=4; R{sub 1}=0.0381, wR{sub 2}=0.0764. The structure consists of distorted [SbCl{sub 6}]{sup 3-} octahedra forming zig-zag [{l_brace}SbCl{sub 5}{r_brace}{sub n}]{sup 2n-} chains that are cross-linked by dimethylammonium [(CH{sub 3}){sub 2}NH{sub 2}]{sup +} cations. The organic and inorganic substr…
Grafting of polymer chains on the surface of carbon nanotubes via nitroxide radical coupling reaction
2016
Poly(butylene succinate)/MWCNTs nanocomposites with improved dispersion and with nanotubes embedded/immobilized into the polymer matrix were here prepared by an alternative "grafting to" method based on thenitroxide radical coupling reaction. Poly(butylene succinate) (PBS) was grafted on the surface of TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy) modified multi-walled carbon nanotubes (MWCNTs) via a nitroxide radical coupling reaction. TEMPO functionalized MWCNTs (MWCNTs-g-TEMPO) were synthesized using the Cu(I)-catalyzed azide/alkyne click chemistry approach and the covalent bond of the nitroxide moieties onto the MWCNTs was confirmed via electron paramagnetic resonance (EPR) spectroscopy.…

Las medidas de integración de los inmigrantes en la Unión Europea. El modelo competencial y los diferentes enfoques territoriales en el sistema españ…
2014
La investigación se centra en el estudio de los programas de integración cívica para inmigrantes, materializados en cursos introductorios y de idioma, desde una perspectiva eminentemente jurídica, examinando su permanente evolución en el contexto de la Unión Europea y su incipiente aparición en España. Este Estado miembro tiene la particularidad de ser aquel en el que el fenómeno migratorio ha comenzado, tenido su punto más álgido e iniciado un significativo descenso en poco más de una década, lo que convierte al país en un estudio de caso ciertamente paradigmático. El objetivo de este trabajo es averiguar si las medidas o condiciones de integración legitimadas por el Principio Básico Común…
