Reimagining career guidance: towards a pluralistic perspective
Difficulties concerning the identified mis-match between supply and demand sides of the labour market are discussed. The variability of career guidance services for young people across Europe is illustrated together with policy initiatives in some cases leading to problems of professional identity and limited support to clients of the service. The risks associated with a monoculture of ‘one size fits all’ approach to guidance practice are discussed. The principles of pluralistic approaches to counselling are discussed with the suggestion that this might prove to be a fertile way forward for career guidance practice
Instabilities in the wake of an inclined prolate spheroid
We investigate the instabilities, bifurcations and transition in the wake
behind a 45-degree inclined 6:1 prolate spheroid, through a series of direct
numerical simulations (DNS) over a wide range of Reynolds numbers (Re) from 10
to 3000. We provide a detailed picture of how the originally symmetric and
steady laminar wake at low Re gradually looses its symmetry and turns unsteady
as Re is gradually increased. Several fascinating flow features have first been
revealed and subsequently analysed, e.g. an asymmetric time-averaged flow
field, a surprisingly strong side force etc. As the wake partially becomes
turbulent, we investigate a dominating coherent wake structure, namely a
helical vortex tube, inside of which a helical symmetry alteration scenario was
recovered in the intermediate wake, together with self-similarity in the far
wake.Comment: Book chapter in "Computational Modeling of Bifurcations and
