Alignment of linear molecules by short duration laser pulses
2005
Alignment of linear molecules is efficiently induced by strong linearly polarized laser pulses. In the case of short pulses with respect to molecular rotation, periodic alignment appears in field-free conditions after the extinction of the field. This manuscript presents three techniques where the value of allows to quantify alignment without molecular dissociation nor additional alignment. They use a weak time-delayed probe pulse which experiences the optical properties of an aligned sample and shows modification of its characteristics. The first of them measures a depolarization due to the birefringence of the sample. The second one is based on the defocusing produced by the spatial distr…
Polarisation attraction and incoherent modulation instability in optical fibers
2006
This thesis, entitled « Polarisation attraction and incoherent modulation instability in optical fibers », presents a theoretical and experimental study of two new processes from the nonlinear optic in optical fibers domain. We introduce in the first chapter some theoretical notions useful for the comprehension of this work. Then, we demonstrate in the second chapter that it is possible to generate some modulation instability in optical fibers using a partially coherent optical beam. We highlight and observe the main properties of the phenomenon. We study the polarisation attraction in isotropic fibers process in the third chapter. Our work proves the existence of the phenomenon, and permit…

First measurement of quarkonium polarization in nuclear collisions at the LHC
2021
The polarization of inclusive J/$\psi$ and $\Upsilon(1{\rm S})$ produced in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=5.02$ TeV at the LHC is measured with the ALICE detector. The study is carried out by reconstructing the quarkonium through its decay to muon pairs in the rapidity region $2.5<y<4$ and measuring the polar and azimuthal angular distributions of the muons. The polarization parameters $\lambda_{\theta}$, $\lambda_{\phi}$ and $\lambda_{\theta\phi}$ are measured in the helicity and Collins-Soper reference frames, in the transverse momentum interval $2<p_{\rm T}<10$ GeV/$c$ and $p_{\rm T}<15$ GeV/$c$ for the J/$\psi$ and $\Upsilon(1{\rm S})$, respectively. The polarization parameter…
Työmarkkinoiden polarisaation yhteys suomalaiseen palkkajakaumaan vuosina 1990-2010
2018
Tämän tutkimuksen tavoitteena on tarkastella suomalaisten työmarkkinoiden polarisoitumista ja sen yhteyttä kokopäivätoimisten palkansaajien palkkajakauman, keskipalkan ja palkkaerojen kehitykseen Suomessa vuosina 1990—2010. Työmarkkinoiden polarisoituminen, eli korkea- ja matalapalkkaisten ammattien työosuuksien kasvu keskipalkkaisten ammattien kustannuksella, on kehittyneissä läntisissä talouksissa laajalti havaittu ilmiö. Tämä tutkimus osoittaa, että myös suomalaisilla työmarkkinoilla on havaittavissa polarisoitumista sekä palkkarakennetilastolla mitattuna vuosina 2005—2015 että tulonjakotilastolla mitattuna vuosina 1990—1995 ja 2001—2010. Työosuuksien kasvu rajautuu 2000-luvulla lähes yk…
Parliamentarisation as Politicisation
2021
Understanding politics as a contingent and controversial activity, politicisation refers to those activities that create or make visible the political quality in the phenomena in question. Parliamentarisation is a distinct strategy of politicisation. In this chapter, parliament refers to a certain procedural and institutional ideal type of acting politically. The parliamentary way of politicising acting and thinking forms a Gedankenbild, a mental image. It is an ideal type that one-sidedly accentuates and intensifies the political way of thinking. The parliamentary way of proceeding politically transcends the given polity: ‘parliament’ is not primarily a parliament ‘of’ a unit, such as the …
The British Parliament and Foreign Policy in the 20th Century : Towards Increasing Parliamentarisation?
2016
This article demonstrates the complexity of the foreign policy involvement of the British parliament during the 20th century. Parliamentary government as such provides some procedural means for involvement in foreign policy debate, in Britain as well as in other countries. Researchers have, nevertheless, often argued that parliaments play a limited role in foreign policy. Approaching our topic by combining the analysis of policy documents with more discourse-oriented analysis of parliamentary debates, we argue that noticeable, but not straightforward, parliamentarisation of foreign policy took place in the course of the 20th century. The aftermath of the First World War led to reconsiderati…
Osaaminen lastensuojelun sosiaalityössä : Esitys asiantuntijuutta tukevasta urapolkumallista
2020
Osana Lapsi-ja perhepalvelujen muutosohjelmaa (LAPE) syntyi havainto siitä, että lastensuojelun osaami-sesta puuttuu kansallisen tason jäsennys. On tarve määritellä lastensuojelussa tarvittavaa osaamista ja sitä tukevia rakenteita. Työryhmä (Lasto) tarttui tähän määrittelyn haasteeseen, koska osaamisen sanoittamisel-la ja osaamista tukevilla rakenteilla nähdään olevan lastensuojelun vaikuttavuuden ja myös työntekijöiden hyvinvoinnin näkökulmasta merkitystä. Lastensuojelulaki antaa puitteet työlle, mutta se ei määrittele am-matillista osaamista ja käytäntöjä.Lastensuojelussa haasteena on sosiaalityöntekijöiden vaihtuvuus ja se, ettei asiakastyössä ole ollut mah-dollisuutta luoda urapolkua. U…
