Kwalitatieve evaluatie van 10 jaar zorgcoördinatie en case management in de Oost-Vlaamse drughulpverlening: een rondvraag bij hulpverleners en cliënten
Sinds 10 jaar wordt door de Provincie Oost-Vlaanderen – in samenwerking met het provinciaal overlegplatform geestelijke gezondheidszorg (PopovGGZ) en alle betrokken voorzieningen – geïnvesteerd in zorgvernieuwing, coördinatie en afstemming van de zorg in de drughulpverlening. Dit heeft naast heel wat ‘onzichtbare’ realisaties (bv. grotere bekendheid van het zorgaanbod, de intakeprocedure en werkwijze van andere voorzieningen, betere samenwerking tussen voorzieningen als gevolg van meer (informele) contactmomenten), ook tot een aantal duidelijk tastbare resultaten geleid. Het betreft onder meer de oprichting van een netwerkcomité middelenmisbruik, de aanstelling van een zorgcoördinator, de uitbouw van een case managementteam en de organisatie van een driewekelijks cliëntenoverleg. Met name deze laatste twee realisaties komen in voorliggend onderzoeksrapport uitgebreid aan bod. We doen dit in de eerste plaats door de direct betrokkenen (cliënten, hulpverleners en verantwoordelijken) zelf aan het woord te laten.
De bevindingen van onze kwalitatieve evaluatie worden afzonderlijk besproken met betrekking tot het cliëntenoverleg en case management. Vooreerst worden beide werkvormen beschreven en worden enkele cijfergegevens meegegeven over de interventie in kwestie. Daarna volgt een beknopte bespreking van de gevolgde methodologie. Bij de rapportage van de onderzoeksresultaten wordt een onderscheid gemaakt tussen de bevindingen van hulpverleners over het cliëntenoverleg, de visie van cliënten over case management en het perspectief van case managers en projectverantwoordelijken over deze laatste interventie. We sluiten af met een aantal globale conclusies en aanbevelingen voor de toekomstige praktijk, die we terugbrachten tot tien concrete suggesties ter optimalisatie van het cliëntenoverleg en het case management. In tegenstelling tot eerdere publicaties beroepen we ons in dit onderzoeksrapport slechts in beperkte mate op de literatuur. In voorliggend rapport wilden we vooral het ‘insider’-perspectief laten primeren en voor meer theoretische beschouwingen verwijzen we dan ook naar eerdere publicaties (cf. Vanderplasschen, 2004)
A semi-analytic model comparison - gas cooling and galaxy mergers
We use stripped-down versions of three semi-analytic galaxy formation models
to study the influence of different assumptions about gas cooling and galaxy
mergers. By running the three models on identical sets of merger trees
extracted from high-resolution cosmological N-body simulations, we are able to
perform both statistical analyses and halo-by-halo comparisons. Our study
demonstrates that there is a good statistical agreement between the three
models used here, when operating on the same merger trees, reflecting a general
agreement in the underlying framework for semi-analytic models. We also show,
however, that various assumptions that are commonly adopted to treat gas
cooling and galaxy mergers can lead to significantly different results, at
least in some regimes. In particular, we find that the different models adopted
for gas cooling lead to similar results for mass scales comparable to that of
our own Galaxy. Significant differences, however, arise at larger mass scales.
These are largely (but not entirely) due to different treatments of the `rapid
cooling' regime, and different assumptions about the hot gas distribution. At
this mass regime, the predicted cooling rates can differ up to about one order
of magnitude, with important implications on the relative weight that these
models give to AGN feedback in order to counter-act excessive gas condensation
in relatively massive haloes at low redshift. Different assumptions in the
modelling of galaxy mergers can also result in significant differences in the
timings of mergers, with important consequences for the formation and evolution
of massive galaxies.Comment: 21 pages, 14 figures. Accepted for publication in MNRAS
Magnetic Phases in Dense Quark Matter
In this paper I discuss the magnetic phases of the three-flavor color
superconductor. These phases can take place at different field strengths in a
highly dense quark system. Given that the best natural candidates for the
realization of color superconductivity are the extremely dense cores of neutron
stars, which typically have very large magnetic fields, the magnetic phases
here discussed could have implications for the physics of these compact
objects.Comment: Presented at VII Latin American Symposium on Nuclear Physics and

Dim galaxies and outer halos of galaxies missed by 2MASS ? The near-infrared luminosity function and density
By using high-resolution and deep Ks band observations of early-type galaxies
of the nearby Universe and of a cluster at z=0.3 we show that the two
luminosity functions (LFs) of the local universe derived from 2MASS data miss a
fair fraction of the flux of the galaxies (more than 20 to 30%) and a whole
population of galaxies of central brightness fainter than the isophote used for
detection, but bright enough to be included in the published LFs. In
particular, the fraction of lost flux increases as the galaxy surface
brightness become fainter. Therefore, the so far derived LF slopes and
characteristic luminosity as well as luminosity density are underestimated.
Other published near-infrared LFs miss flux in general, including the LF of the
distant field computed in a 3 arcsec aperture.Comment: A&A in pres
Diversity Of Short Gamma-Ray Burst Afterglows From Compact Binary Mergers Hosting Pulsars
Short gamma-ray bursts (sGRBs) are widely believed to result from the mergers
of compact binaries. This model predicts an afterglow that bears the
characteristic signatures of a constant, low density medium, including a smooth
prompt-afterglow transition, and a simple temporal evolution. However, these
expectations are in conflict with observations for a non-negligible fraction of
sGRB afterglows. In particular, the onset of the afterglow phase for some of
these events appears to be delayed and, in addition, a few of them exhibit
late- time rapid fading in their lightcurves. We show that these peculiar
observations can be explained independently of ongoing central engine activity
if some sGRB progenitors are compact binaries hosting at least one pulsar. The
Poynting flux emanating from the pulsar companion can excavate a bow-shock
cavity surround- ing the binary. If this cavity is larger than the shock
deceleration length scale in the undisturbed interstellar medium, then the
onset of the afterglow will be delayed. Should the deceleration occur entirely
within the swept-up thin shell, a rapid fade in the lightcurve will ensue. We
identify two types of pulsar that can achieve the conditions necessary for
altering the afterglow: low field, long lived pulsars, and high field pulsars.
We find that a sizable fraction (~20-50%) of low field pulsars are likely to
reside in neutron star binaries based on observations, while their high field
counterparts are not. Hydrodynamical calculations motivated by this model are
shown to be in good agreement with observations of sGRB afterglow lightcurves.Comment: Accepted to ApjL. Direct comparison to observed X-Ray afterglows now

ARGO CMB Anisotropy Measurement Constraints on Open and Flat-Lambda CDM Cosmogonies
We use data from the ARGO cosmic microwave background (CMB) anisotropy
experiment to constrain cosmogonies. We account for the ARGO beamwidth and
calibration uncertainties, and marginalize over the offset removed from the
data. Our derived amplitudes of the CMB anisotropy detected by the ARGO
experiment are smaller than those derived previously.
We consider open and spatially-flat-Lambda cold dark matter cosmogonies, with
clustered-mass density parameter Omega_0 in the range 0.1-1, baryonic-mass
density parameter Omega_B in the range (0.005-0.029)h^{-2}, and age of the
universe t_0 in the range (10--20) Gyr. Marginalizing over all parameters but
Omega_0, the ARGO data favors an open (spatially-flat-Lambda) model with
Omega_0= 0.23 (0.1). However, these numerical values are model dependent.
At the 2 sigma confidence level model normalizations deduced from the ARGO
data are consistent with those drawn from the UCSB South Pole 1994, MAX 4+5,
White Dish, and SuZIE data sets. The ARGO open model normalizations are also
consistent with those deduced from the DMR data. However, for most
spatially-flat-Lambda models the DMR normalizations are more than 2 sigma above
the ARGO ones.Comment: 21 pages of latex. Uses aaspp4.sty. 8 figures included. ApJ in pres
Addressing the Global Tragedy of Needless Pain: Rethinking the United Nations Single Convention on Narcotic Drugs
The lack of medical availability of effective pain medication is an enduring and expanding global health calamity. Despite important medical advances, pain remains severely under-treated worldwide, particularly in developing countries. This article contributes to the discussion of this global health crisis by considering international legal and institutional mechanisms to promote wider accessibility to critical narcotic drugs for pain relief
A composite K-band Luminosity Function for Cluster Galaxies
We present a composite K-band luminosity function for 10 clusters at low
redshift, where member galaxies are identified from an existing spectroscopic
survey (the 2dF galaxy redshift survey). Our kinematically selected K-band
luminosity function is well fitted by a Schechter function with and over . This is very
similar to the 2dF field value and suggests that the integrated mass accretion
history of galaxies does not vary strongly with environmentComment: 3 pages, 1 figure, Astronomische Nachrichten (JENAM 2008 Symposium 6
