The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Changing careers and trajectories. How individuals cope with organisational change and restructuring

The book focuses on changes in individual careers, trajectories on the labour market and occupational identities. It analyses the driving forces behind these changes and considers wider societal trends concerning the changing meaning of work.The conclusions highlight key trends in careers and trajectories: the widening of the spectrum of career models; the multiplication of fragmented trajectories; the plurality of models of identity formation at work; the new balance between internal and external labour markets; the individualisation of human resource management; the decline of traditional forms of collective involvement and the emergence of new forms of social bonding at work; and finally the increasing importance of the expressive dimension in the relation to work.[...

Het genderperspectief in het sociaal overleg op sectorniveau. Een analyse van en voor het ACV-optreden

De ongelijkheid tussen vrouwen en mannen op de Belgische arbeidsmarkt is een hardnekkig gegeven. In dit rapport in, samenwerking met het ACV, vatten de basisindicatoren van deze ongelijkheid nogmaals kort samen. Vervolgens overlopen we kort hoe beleidsmatig wordt getracht deze ongelijkheden weg te werken. ‘Gendermainstreaming’ of integratie van de genderdimensie in elk soort beleid krijgt daarbij vandaag de hoofdaandacht. Na een kort overzicht van hoe deze strategie programmatorisch is vertaald door het ACV, wordt duidelijk gemaakt op welke wijze het sectorale CAO-overleg in deze ACV-strategie van gendermainstreaming een welbepaalde rol wordt toebedeeld. Het is deze rol die in dit rapport systematisch wordt geanalyseerd.nrpages: 87status: publishe
