Mental health professionals' feelings and attitudes towards coercion.
Despite absence of clear evidence to assert that the use of coercion in psychiatry is practically and clinically helpful or effective, coercive measures are widely used. Current practices seem to be based on institutional cultures and decision-makers' attitudes towards coercion rather than led by recommendations issued from the scientific literature. Therefore, the main goal of our study was to describe mental health professionals' feelings and attitudes towards coercion and the professionals' characteristics associated with them.
Mental health professionals working in the Department of Psychiatry of Lausanne University Hospital, Switzerland, were invited to participate to an online survey. A questionnaire explored participants' sociodemographic characteristics, professional background and current working context, and their feelings and attitudes towards coercion. Exploratory Structural Equation Modelling (ESEM) was used to determine the structure of mental health professionals' feelings and attitudes towards coercion and to estimate to which extent sociodemographic and professional characteristics could predict their underlying dimensions.
130 mental health professionals completed the survey. Even if a large number considered coercion a violation of fundamental rights, an important percentage of them agreed that coercion was nevertheless indispensable in psychiatry and beneficial to the patients. ESEM revealed that professionals' feelings and attitudes towards coercion could be described by four main dimensions labelled "Internal pressure", "Emotional impact", "External pressure" and "Relational involvement". The personal as well as the professional proximity with people suffering from mental disorders influences professionals' feeling and attitudes towards coercion.
As voices recommend the end of coercion in psychiatry and despite the lack of scientific evidence, many mental health professionals remain convinced that it is a requisite tool beneficial to the patients. Clinical approaches that enhance shared decision making and give the opportunity to patients and professionals to share their experience and feelings towards coercion and thus alleviate stress among them should be fostered and developed
Oligonucleotide Sensor Based on Selective Capture of Upconversion Nanoparticles Triggered by Target-Induced DNA Interstrand Ligand Reaction
The Multiwavelength Survey by Yale-Chile (MUSYC): Survey Design and Deep Public UBVRIz' Images and Catalogs of the Extended Hubble Deep Field South
We present UBVRIz' optical images of the 0.32 square degree Extended Hubble
Deep Field South. This is one of four fields comprising the MUSYC survey, which
is optimized for the study of galaxies at z=3, AGN demographics, and Galactic
structure. We calculate corrected aperture photometry and its uncertainties and
find through tests that these provide a significant improvement upon standard
techniques. Our photometric catalog of 62968 objects is complete to a total
magnitude of R_AB=25. We select z=3 Lyman break galaxy (LBG) candidates from
their UVR colors and find a sky surface density of 1.4/sq. arcmin and an
angular correlation function w(theta) = 2.3+-1.0 theta^{-0.8}. (Abridged)Comment: Astrophysical Journal Supplements, in press, 19 pages including 19

Cohesive strength of nanocrystalline ZnO:Ga thin films deposited at room temperature
In this study, transparent conducting nanocrystalline ZnO:Ga (GZO) films were deposited by dc magnetron sputtering at room temperature on polymers (and glass for comparison). Electrical resistivities of 8.8 × 10-4 and 2.2 × 10-3 Ω cm were obtained for films deposited on glass and polymers, respectively. The crack onset strain (COS) and the cohesive strength of the coatings were investigated by means of tensile testing. The COS is similar for different GZO coatings and occurs for nominal strains approx. 1%. The cohesive strength of coatings, which was evaluated from the initial part of the crack density evolution, was found to be between 1.3 and 1.4 GPa. For these calculations, a Young's modulus of 112 GPa was used, evaluated by nanoindentation
Strange particle production in proton-proton collisions at TeV with ALICE at the LHC
The production of mesons containing strange quarks (K, ) and both
singly and doubly strange baryons (, Anti-, and
+Anti-) are measured at central rapidity in pp collisions at
= 0.9 TeV with the ALICE experiment at the LHC. The results are
obtained from the analysis of about 250 k minimum bias events recorded in 2009.
Measurements of yields (dN/dy) and transverse momentum spectra at central
rapidities for inelastic pp collisions are presented. For mesons, we report
yields () of 0.184 0.002 stat. 0.006 syst. for K and
0.021 0.004 stat. 0.003 syst. for . For baryons, we find
= 0.048 0.001 stat. 0.004 syst. for , 0.047
0.002 stat. 0.005 syst. for Anti- and 0.0101 0.0020 stat.
0.0009 syst. for +Anti-. The results are also compared with
predictions for identified particle spectra from QCD-inspired models and
provide a baseline for comparisons with both future pp measurements at higher
energies and heavy-ion collisions.Comment: 33 pages, 21 captioned figures, 10 tables, authors from page 28,

Elliptic flow of charged particles in Pb-Pb collisions at 2.76 TeV
We report the first measurement of charged particle elliptic flow in Pb-Pb
collisions at 2.76 TeV with the ALICE detector at the CERN Large Hadron
Collider. The measurement is performed in the central pseudorapidity region
(||<0.8) and transverse momentum range 0.2< < 5.0 GeV/. The
elliptic flow signal v, measured using the 4-particle correlation method,
averaged over transverse momentum and pseudorapidity is 0.087 0.002
(stat) 0.004 (syst) in the 40-50% centrality class. The differential
elliptic flow v reaches a maximum of 0.2 near = 3
GeV/. Compared to RHIC Au-Au collisions at 200 GeV, the elliptic flow
increases by about 30%. Some hydrodynamic model predictions which include
viscous corrections are in agreement with the observed increase.Comment: 10 pages, 4 captioned figures, published version, figures at

Suppression of charged particle production at large transverse momentum in central Pb-Pb collisions at TeV
Inclusive transverse momentum spectra of primary charged particles in Pb-Pb
collisions at = 2.76 TeV have been measured by the ALICE
Collaboration at the LHC. The data are presented for central and peripheral
collisions, corresponding to 0-5% and 70-80% of the hadronic Pb-Pb cross
section. The measured charged particle spectra in and GeV/ are compared to the expectation in pp collisions at the same
, scaled by the number of underlying nucleon-nucleon
collisions. The comparison is expressed in terms of the nuclear modification
factor . The result indicates only weak medium effects ( 0.7) in peripheral collisions. In central collisions,
reaches a minimum of about 0.14 at -7GeV/ and increases
significantly at larger . The measured suppression of high- particles is stronger than that observed at lower collision energies,
indicating that a very dense medium is formed in central Pb-Pb collisions at
the LHC.Comment: 15 pages, 5 captioned figures, 3 tables, authors from page 10,

Two-pion Bose-Einstein correlations in central Pb-Pb collisions at = 2.76 TeV
The first measurement of two-pion Bose-Einstein correlations in central Pb-Pb
collisions at TeV at the Large Hadron Collider is
presented. We observe a growing trend with energy now not only for the
longitudinal and the outward but also for the sideward pion source radius. The
pion homogeneity volume and the decoupling time are significantly larger than
those measured at RHIC.Comment: 17 pages, 5 captioned figures, 1 table, authors from page 12,
