Results from the Scottish national HAI prevalence survey
A national point prevalence survey was undertaken over the period of one calendar year in Scotland from October 2005 to October 2006. The prevalence of healthcare-associated infection (HAI) was 9.5% in acute hospitals and 7.3% in non-acute hospitals. The highest prevalence of HAI in acute hospital inpatients was found in the following specialties: care of the elderly (11.9%), surgery (11.2%), medicine (9.6%) and orthopaedics (9.2%). The lowest prevalence was found in obstetrics (0.9%). The most common types of HAI in acute hospital inpatients were: urinary tract infections (17.9% of all HAI), surgical site infections (15.9%) and gastrointestinal infections (15.4%). In non-acute hospitals one in ten inpatients in two specialties (combined) medicine (11.4%) and care of the elderly (7.8%) was found to have HAI, and one in 20 inpatients in psychiatry (5.0%) had HAI. In non-acute hospital patients, urinary tract infections were frequent (28.1% of all HAI) and similarly skin and soft tissue infection (26.8% of all HAI). When combined, these two HAI types affected 4% of all the inpatients in non-acute hospitals. This is the first survey of its kind in Scotland and describes the burden of HAI at a national level
Homodyne detection for measuring internal quantum correlations of optical pulses
A new method is described for determining the quantum correlations at
different times in optical pulses by using balanced homodyne detection. The
signal pulse and sequences of ultrashort test pulses are superimposed, where
for chosen distances between the test pulses their relative phases and
intensities are varied from measurement to measurement. The correlation
statistics of the signal pulse is obtained from the time-integrated difference
photocurrents measured.Comment: 7 pages, A4.sty include
Female educatorsâ perceptions of employment opportunities in the United Arab Emirates
This article examines the way female educators experience barriers to employment opportunities in the education system of the United Arab Emirates. An exploratory qualitative research design using interviews and focus group sessions was used to collect data from national female educators at different stages of their careers. Manifestations of the category âemployment barriersâ included social barriers to women and work, education as career choice, âdelays and waiting listsâ, and opposition to employment in the private education sector. Manifestations of the category âbarriers to career progressionâ included, conflict of roles, âwaiting for them to promote meâ, lack of networking opportunities, âbig sisterâ mentoring, challenges to academic development and training and gender discrimination. Recommendations relating to strategies that could facilitate national female educator entry into and career progression in the education sector are provided.Educational Leadership and Managemen
The Ising-Kondo lattice with transverse field: an f-moment Hamiltonian for URu2Si2?
We study the phase diagram of the Ising-Kondo lattice with transverse
magnetic field as a possible model for the weak-moment heavy-fermion compound
URu2Si2, in terms of two low-lying f singlets in which the uranium moment is
coupled by on-site exchange to the conduction electron spins. In the mean-field
approximation for an extended range of parameters, we show that the conduction
electron magnetization responds logarithmically to f-moment formation, that the
ordered moment in the antiferromagnetic state is anomalously small, and that
the Neel temperature is of the order observed. The model gives a qualitatively
correct temperature-dependence, but not magnitude, of the specific heat. The
majority of the specific heat jump at the Neel temperature arises from the
formation of a spin gap in the conduction electron spectrum. We also discuss
the single-impurity version of the model and speculate on ways to increase the
specific heat coefficient. In the limits of small bandwidth and of small
Ising-Kondo coupling, we find that the model corresponds to anisotropic
Heisenberg and Hubbard models respectively.Comment: 20 pages RevTeX including 5 figures (1 in LaTeX, 4 in uuencoded EPS),

New Upper Limits on the Tau Neutrino Mass from Primordial Helium Considerations
In this paper we reconsider recently derived bounds on tau neutrinos,
taking into account previously unaccounted for effects. We find that, assuming
that the neutrino life-time is longer than , the constraint
rules out masses in the range
for Majorana neutrinos and
for Dirac neutrinos. Given that the present
laboratory bound is 35 MeV, our results lower the present bound to and
for Majorana and Dirac neutrinos respectively.Comment: 9 pages (2 figures available upon request), UM-AC-93-0
Purity of Gaussian states: measurement schemes and time-evolution in noisy channels
We present a systematic study of the purity for Gaussian states of
single-mode continuous variable systems. We prove the connection of purity to
observable quantities for these states, and show that the joint measurement of
two conjugate quadratures is necessary and sufficient to determine the purity
at any time. The statistical reliability and the range of applicability of the
proposed measurement scheme is tested by means of Monte Carlo simulated
experiments. We then consider the dynamics of purity in noisy channels. We
derive an evolution equation for the purity of general Gaussian states both in
thermal and squeezed thermal baths. We show that purity is maximized at any
given time for an initial coherent state evolving in a thermal bath, or for an
initial squeezed state evolving in a squeezed thermal bath whose asymptotic
squeezing is orthogonal to that of the input state.Comment: 9 Pages, 6 Figures; minor errors correcte
High Purity Pion Beam at TRIUMF
An extension of the TRIUMF M13 low-energy pion channel designed to suppress
positrons based on an energy-loss technique is described. A source of beam
channel momentum calibration from the decay pi+ --> e+ nu is also described.Comment: 5 page
Conditional generation of sub-Poissonian light from two-mode squeezed vacuum via balanced homodyne detection on idler mode
A simple scheme for conditional generation of nonclassical light with
sub-Poissonian photon-number statistics is proposed. The method utilizes
entanglement of signal and idler modes in two-mode squeezed vacuum state
generated in optical parametric amplifier. A quadrature component of the idler
mode is measured in balanced homodyne detector and only those experimental runs
where the absolute value of the measured quadrature is higher than certain
threshold are accepted. If the threshold is large enough then the conditional
output state of signal mode exhibits reduction of photon-number fluctuations
below the coherent-state level.Comment: 7 pages, 6 figures, REVTe
