C?est souvent de cette manière que les professionnels de la politique, les journalistes ou les citoyens appréhendent l?usage politique des médias. Cette formulation fait pourtant obstacle à l?explication des processus sociaux à l??uvre dans la médiatisation de la politique. Afin de montrer comment la médiatisation peut être agissante en politique, cet ouvrage met à l?épreuve le concept de « capital médiatique », une forme de capital symbolique tiré de la médiatisation. Les contributions examinent les opérations d?accumulation, d?appropriation, de légitimation, de conversion ou de rentabilisation de ce capital, à partir d?études de cas (Louise Michel, José Bové, Emmanuel Macron ou les parlementaires). L?ouvrage n?est pas seulement une étude de la médiatisation du politique : c?est aussi une contribution à la sociologie du champ politique et des ressources qui y prévalent. Il analyse le travail des agents politiques en lien avec tout ou partie du champ journalistique, et plus largement dans un espace médiatique profondément transformé par le numérique. Il conclut à l?inégale rentabilité du capital médiatique selon la position dans le champ politique. Les réflexions engagées invitent à réfléchir, par analogie, à d?autres espaces pour lesquels la reconnaissance médiatique est un enjeu stratégique et semble être une ressource valorisée. 606 $aPolitical Science 606 $apolitique 606 $ainformation 606 $acommunication 610 $apolitique 610 $ainformation 610 $acommunication 615 4$aPolitical Science 615 4$apolitique 615 4$ainformation 615 4$acommunication 700 $aBourad$b Aïcha$01296883 701 $aDahani$b Safia$01296884 701 $aDarras$b Éric$01285833 701 $aDesrumaux$b Clément$01296885 701 $aDulong$b Delphine$01296886 701 $aEdelbloude$b Johanna$01296887 701 $aFerron$b Benjamin$01296888 701 $aGaxie$b Daniel$0245893 701 $aLeroux$b Pierre$0465577 701 $aMarchetti$b Dominique$01287297 701 $aNeihouser$b Marie$01250340 701 $aNeveu$b Erik$0123957 701 $aNollet$b Jérémie$01292612 701 $aRiutort$b Philippe$01288098 701 $aRoginsky$b Sandrine$01296889 701 $aVerhaeghe$b Sidonie$01288099 701 $aDesrumaux$b Clément$01296885 701 $aNollet$b Jérémie$01292612 801 0$bFR-FrMaCLE 906 $aBOOK 912 $a9910548296003321 996 $aUn capital médiatique $93024273 997 $aUNINA LEADER 05195nam 22006374a 450 001 9911019229203321 005 20200520144314.0 010 $a9786612341687 010 $a9781282341685 010 $a1282341685 010 $a9780470695975 010 $a0470695978 010 $a9780470695227 010 $a0470695226 035 $a(CKB)1000000000687495 035 $a(EBL)470742 035 $a(SSID)ssj0000291568 035 $a(PQKBManifestationID)11223121 035 $a(PQKBTitleCode)TC0000291568 035 $a(PQKBWorkID)10254071 035 $a(PQKB)11183048 035 $a(MiAaPQ)EBC470742 035 $a(OCoLC)232611582 035 $a(Perlego)2755612 035 $a(EXLCZ)991000000000687495 100 $a20020419d2003 uy 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 10$aChromosomes $eorganization and function /$fAdrian T.

The organisation and behaviour of chromosomes is central to genetics and the equal segregation of genes and chromosomes into daughter cells at cell division is vital. This text aims to provide a clear and straightforward explanation of these complex processes.Following a brief historical introduction, the text covers the topics of cell cycle dynamics and 606 $aChromosomes 615 0$aChromosomes. 676 $a572.8/7 700 $aSumner$b A.
