Improving access to quality clinical nurse teaching : a partnership between Australia and Vietnam

Until recently, standards to guide nursing education and practice in Vietnam were nonexistent. This paper describes the development and implementation of a clinical teaching capacity building project piloted in Hanoi, Vietnam. The project was part of a multi-component capacity building program designed to improve nurse education in Vietnam. Objectives of the project were to develop a collaborative clinically-based teaching model that encourages evidence-based, student-centred clinical learning. The model incorporated strategies to promote development of nursing practice to meet national competency standards.\ud
\ud
Thirty nurse teachers from two organisations in Hanoi participated in the program. These participants attended three workshops, and completed applied assessments, where participants implemented concepts from each workshop. The assessment tasks were planning, implementing and evaluating clinical teaching. On completion of the workshops, twenty participants undertook a study tour in Australia to refine the teaching model and develop an action plan for model implementation in both organisations, with an aim to disseminate the model across Vietnam.\ud
\ud
Significant changes accredited to this project have been noted on an individual and organisational level. Dissemination of this clinical teaching model has commenced in Ho Chi Minh, with further plans for more in-depth dissemination to occur throughout the country
Jet momentum dependence of jet quenching in PbPb collisions at \sqrt{s} = 2.76 TeV

Dijet production in PbPb collisions at a nucleon–nucleon center-of-mass energy of 2.76 TeV is studied with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 150 μb−1 is analyzed. Jets are reconstructed using combined information from tracking and calorimetry, using the anti-kT algorithm with R=0.3. The dijet momentum balance and angular correlations are studied as a function of collision centrality and leading jet transverse momentum. For the most peripheral PbPb collisions, good agreement of the dijet momentum balance distributions with pp data and reference calculations at the same collision energy is found, while more central collisions show a strong imbalance of leading and subleading jet transverse momenta attributed to the jet-quenching effect. The dijets in central collisions are found to be more unbalanced than the reference, for leading jet transverse momenta up to the highest values studied
Low-temperature photocarrier dynamics in monolayer MoS2

The band structure of MoS2 strongly depends on the number of layers, and a transition from indirect to direct-gap semiconductor has been observed recently for a single layer of MoS2. Single-layer MoS2 therefore becomes an efficient emitter of photoluminescence even at room temperature. Here, we report on scanning Raman and on temperature-dependent, as well as time-resolved photoluminescence measurements on single-layer MoS2 flakes prepared by exfoliation. We observe the emergence of two distinct photoluminescence peaks at low temperatures. The photocarrier recombination at low temperatures occurs on the few-picosecond timescale, but with increasing temperatures, a biexponential photoluminescence decay with a longer-lived component is observed
Gender differences in behavioral regulation in four societies: The United States, Taiwan, South Korea, and China

© 2013 Elsevier Inc. The current study investigates gender differences in behavioral regulation in four societies: the United States, Taiwan, South Korea, and China. Directly assessed individual behavioral regulation (Head–Toes–Knees–Shoulders, HTKS), teacher-rated classroom behavioral regulation (Child Behavior Rating Scale, CBRS) and a battery of school readiness assessments (mathematics, vocabulary, and early literacy) were used with 814 young children (ages 3–6 years). Results showed that girls in the United States had significantly higher individual behavioral regulation than boys, but there were no significant gender differences in any Asian societies. In contrast, teachers in Taiwan, South Korea, as well as the United States rated girls as significantly higher than boys on classroom behavioral regulation. In addition, for both genders, individual and classroom behavioral regulation were related to many aspects of school readiness in all societies for girls and boys. Universal and culturally specific findings and their implications are discussed
Fluvial deposits as an archive of early human activity: progress during the 20 years of the Fluvial Archives Group

Fluvial sedimentary archives are important repositories for\ud
Lower and Middle Palaeolithic artefacts throughout the 'Old World', especially in Europe, where the beginning of their study coincided with the realisation that early humans were of great antiquity. Now that many river terrace sequences can be reliably dated and correlated with the globally valid marine isotope record, potentially useful patterns can be recognized in the distribution of the find-spots of the artefacts that constitute the large collections that were assembled during the years of manual gravel extraction. This paper reviews the advances during the past two decades in knowledge of hominin occupation based on artefact occurrences in fluvial contexts, in Europe, Asia and Africa. As such it is an update of a comparable review in 2007, at the end of IGCP Project no. 449, which had instigated the compilation of fluvial records from around the world during 2000-2004, under the auspices of the Fluvial Archives Group. An overarching finding is the confirmation of the well established view that in Europe there is a demarcation between handaxe making in the west and flake-core industries in the east, although on a wider scale that pattern is undermined by the increased numbers of Lower Palaeolithic bifaces now recognized in East Asia. It is also apparent that, although it seems to have appeared at different places and at\ud
different times in the later Lower Palaeolithic, the arrival of Levallois technology as a global phenomenon was similarly timed across the area occupied by Middle Pleistocene hominins, at around 0.3 Ma
Individualized versus conventional ovarian stimulation for in vitro fertilization : a multicenter, randomized, controlled, assessor-blinded, phase 3 noninferiority trial

Objective: To compare the efficacy and safety of follitropin delta, a new human recombinant FSH with individualized dosing based on serum antimullerian hormone (AMH) and body weight, with conventional follitropin alfa dosing for ovarian stimulation in women undergoing IVF. 
Design: Randomized, multicenter, assessor-blinded, noninferiority trial (ESTHER-1). 
Setting: Reproductive medicine clinics. 
Patient(s): A total of 1,329 women (aged 18-40 years). 
Intervention(s): Follitropin delta (AMH <15 pmol/L: 12 mg/d; AMH >= 15 pmol/L: 0.10-0.19 mu g/kg/d; maximum 12 mg/d), or follitropin alfa (150 IU/d for 5 days, potential subsequent dose adjustments; maximum 450 IU/d). 
Main Outcomes Measure(s): Ongoing pregnancy and ongoing implantation rates; noninferiority margins -8.0%. 
Result(s): Ongoing pregnancy (30.7% vs. 31.6%; difference -0.9% [95% confidence interval (CI) -5.9% to 4.1%]), ongoing implantation (35.2% vs. 35.8%; -0.6% [95% CI -6.1% to 4.8%]), and live birth (29.8% vs. 30.7%; -0.9% [95% CI -5.8% to 4.0%]) rates were similar for individualized follitropin delta and conventional follitropin alfa. Individualized follitropin delta resulted in more women with target response (8-14 oocytes) (43.3% vs. 38.4%), fewer poor responses (fewer than four oocytes in patients with AMH < 15 pmol/L) (11.8% vs. 17.9%), fewer excessive responses (>= 15 or >= 20 oocytes in patientswithAMH >= 15pmol/L) (27.9% vs. 35.1% and 10.1% vs. 15.6%, respectively), and fewermeasures taken to prevent ovarian hyperstimulation syndrome (2.3% vs. 4.5%), despite similar oocyte yield (10.0 +/- 5.6 vs. 10.4 +/- 6.5) and similar blastocyst numbers (3.3 +/- 2.8 vs. 3.5 +/- 3.2), and less gonadotropin use (90.0 +/- 25.3 vs. 103.7 +/- 33.6 mg). 
Conclusion(s): Optimizing ovarian response in IVF by individualized dosing according to pretreatment patient characteristics results in similar efficacy and improved safety compared with conventional ovarian stimulation
First measurement of the helicity asymmetry E in η photoproduction on the proton

International audienceResults are presented for the first measurement of the double-polarization helicity asymmetry E for the η photoproduction reaction γ p → ηp. Data were obtained using the FROzen Spin Target (FROST) with the CLAS spectrometer in Hall B at Jefferson Lab, covering a range of center-of-mass energy W from threshold to 2.15 GeV and a large range in center-of-mass polar angle. As an initial application of these data, the results have been incorporated into the Jülich–Bonn model to examine the case for the existence of a narrow N * resonance between 1.66 and 1.70 GeV. The addition of these data to the world database results in marked changes in the predictions for the E observable from that model. Further comparison with several theoretical approaches indicates these data will significantly enhance our understanding of nucleon resonances
Brexit or bremain? A person and social analysis of voting decisions in the EU referendum

The period following the UK’s EU referendum in 2016 foreshadows significant social and political change in the UK. The current research draws on social psychological theories to empirically examine the drivers of voting decisions during the referendum. We report the results of a prospective study using structural equation modelling with data (N = 244) collected just before, and self-reported voting behavior immediately following (N = 197), the EU referendum. We employ a person and social approach to examine the additive roles of worldview, conservatism, social identity, and intergroup threat as predictors of voting intentions and behavior. Results showed that person factors (worldview and conservatism) predicted voting intentions through social factors (European identity and realistic threat), and that intentions predicted behavior. The results highlight the importance of addressing threat-based intergroup rhetoric, and the potential of common ingroup identity to mitigate psychological threat
Communication: Transition State Theory for dissipative systems without a dividing surface

Transition state theory is a central cornerstone in reaction dynamics. Its key step is the identification of a dividing surface that is crossed only once by all reactive trajectories. This assumption is often badly violated, especially when the reactive system is coupled to an environment. The calculations made in this way then overestimate the reaction rate and the results depend critically on the choice of the dividing surface. In this Communication, we study the phase space of a stochastically driven system close to an energetic barrier in order to identify the geometric structure unambiguously determining the reactive trajectories, which is then incorporated in a simple rate formula for reactions in condensed phase that is both independent of the dividing surface and exact
A turnover in the galaxy main sequence of star formation at M*∼ 10¹⁰ M☉ for redshifts z< 1.3

The relationship between galaxy star formation rates (SFRs) and stellar masses (M∗) is reexamined using a
mass-selected sample of ∼62,000 star-forming galaxies at z  1.3 in the COSMOS 2 deg²field. Using new
far-infrared photometry from Herschel-PACS and SPIRE and Spitzer-MIPS 24μm, along with derived infrared
luminosities from the NRK method based on galaxies’ locations in the restframe color–color diagram (NUV − r)
versus (r − K), we are able to more accurately determine total SFRs for our complete sample. At all redshifts, the
relationship between median SFR and M∗ follows a power law at low stellar masses, and flattens to nearly constant
SFR at high stellar masses. We describe a new parameterization that provides the best fit to the main sequence and
characterizes the low mass power-law slope, turnover mass, and overall scaling. The turnover in the main sequence
occurs at a characteristic mass of about M0 ∼ 10¹⁰ Mʘ at all redshifts. The low mass power-law slope ranges from
0.9–1.3 and the overall scaling rises in SFR as a function of (1 +z)⁴˙¹²±⁰˙¹⁰. A broken power-law fit below and above
the turnover mass gives relationships of SFR ∝ M⁰˙⁸⁸±⁰˙⁰⁶ ∗ below the turnover mass and SFR ∝ M⁰˙²⁷±⁰˙⁰⁴ ∗ above the turnover mass. Galaxies more massive than M∗  1010 M  have a much lower average specific star formation rate (sSFR) than would be expected by simply extrapolating the traditional linear fit to the main sequence found for less massive galaxies
Characterization of two receptors for TRAIL.

Two receptors for TRAIL, designated TRAIL-R2 and TRAIL-R3, have been identified. Both are members of the tumor necrosis factor receptor family. TRAIL-R2 is structurally similar to the death-domain-containing receptor TRAIL-R1 (DR-4), and is capable of inducing apoptosis. In contrast, TRAIL-R3 does not promote cell death. TRAIL-R3 is highly glycosylated and is membrane bound via a putative phosphatidylinositol anchor. The extended structure of TRAIL-R3 is due to the presence of multiple threonine-, alanine-, proline- and glutamine-rich repeats (TAPE repeats). TRAIL-R2 shows a broad tissue distribution, whereas the expression of TRAIL-R3 is restricted to peripheral blood lymphocytes (PBLs) and skeletal muscle. All three TRAIL receptors bind TRAIL with similar affinity, suggesting a complex regulation of TRAIL-mediated signals
Maternal effect on female caste determination in a social insect.

Caste differentiation and division of labor are the hallmarks of social insect colonies [1, 2]. The current dogma for female caste differentiation is that female eggs are totipotent, with morphological and physiological differences between queens and workers stemming from a developmental switch during the larval stage controlled by nutritional and other environmental factors (e.g., [3-8]). In this study, we tested whether maternal effects influence caste differentiation in Pogonomyrmex harvester ants. By conducting crossfostering experiments we identified two key factors in the process of caste determination. New queens were produced only from eggs laid by queens exposed to cold. Moreover, there was a strong age effect, with development into queens occurring only in eggs laid by queens that were at least two years old. Biochemical analyses further revealed that the level of ecdysteroids was significantly lower in eggs developing into queens than workers. By contrast, we found no significant effect of colony size or worker exposure to cold, suggesting that the trigger for caste differentiation may be independent of the quantity and quality of resources provided to larvae. Altogether these data demonstrate that the developmental fate of female brood is strongly influenced by maternal effects in ants of the genus Pogonomyrmex
The Environmental Kuznets Curve: The Role of Renewable and Non-Renewable Energy Consumption and Trade Openness

We use panel cointegration techniques to investigate the causal relationship between CO2 emissions, renewable and non-renewable energy consumption, and trade openness in three different models for a panel of twenty five OECD countries over the period 1980-2009. Also the validity of the Environmental Kuznets Curve (EKC) hypothesis has been tested for these countries. Short-run Granger causality tests show the existence of a unidirectional causality running from the square of per capita output to per capita CO2 emissions and per capita non-renewable energy consumption and a unidirectional causality running from per capita real exports to per capita CO2 emissions. There is an indirect short-run causality running from per capita output to per capita non-renewable energy consumption. In the long-run, the FMOLS and DOLS estimates suggest that per capita GDP and per capita non-renewable energy consumption have a positive impact on per capita CO2 emissions. The long-run estimates suggest that the square of per capita GDP, per capita renewable energy consumption, and per capita real exports and imports have a negative impact on per capita CO2 emissions. Therefore, more trade openness and more use of renewable energy are efficient strategies to combat global warming.
Chern-Simons AdS_5 supergravity in a Randall-Sundrum background

Chern-Simons AdS supergravity theories are gauge theories for the super-AdS
group. These theories possess a fermionic symmetry which differs from standard
supersymmetry. In this paper, we study five-dimensional Chern-Simons AdS
supergravity in a Randall-Sundrum scenario with two Minkowski 3-branes. After
making modifications to the D = 5 Chern-Simons AdS supergravity action and
fermionic symmetry transformations, we obtain a Z_2-invariant total action S =
\tilde{S}_bulk + S_brane and fermionic transformations \tilde{\delta}_\epsilon.
While \tilde{\delta}_\epsilon \tilde{S}_bulk = 0, the fermionic symmetry is
broken by S_brane. Our total action reduces to the original Randall-Sundrum
model when \tilde{S}_bulk is restricted to its gravitational sector. We solve
the Killing spinor equations for a bosonic configuration with vanishing su(N)
and u(1) gauge fields.Comment: 15 pages; minor typos correcte
Spectroscopy and multiband photometry of the afterglow of intermediate
  duration gamma-ray burst 040924 and its host galaxy

We present optical photometry and spectroscopy of the afterglow and host
galaxy of gamma-ray burst 040924. This GRB had a rather short duration of T90
~2.4s, and a well sampled optical afterglow light curve. We aim to use this
dataset to find further evidence that this burst is consistent with a massive
star core-collapse progenitor. We combine the afterglow data reported here with
data taken from the literature and compare the host properties with survey
data. We find that the global behaviour of the optical afterglow is well fit by
a broken power-law, with a break at ~0.03 days. We determine the redshift z =
0.858 +/- 0.001 from the detected emission lines in our spectrum. Using the
spectrum and photometry we derive global properties of the host, showing it to
have similar properties to long GRB hosts. We detect the [Ne III] emission line
in the spectrum, and compare the fluxes of this line of a sample of 15 long GRB
host galaxies with survey data, showing the long GRB hosts to be comparable to
local metal-poor emission line galaxies in their [Ne III] emission. We fit the
supernova bump accompanying this burst, and find that it is similar to other
long GRB supernova bumps, but fainter. All properties of GRB 040924 are
consistent with an origin in the core-collapse of a massive star: the
supernova, the spectrum and SED of the host and the afterglow.Comment: A&A submitted. 10 pages, 4 figure
Effect of mobile telephones on sperm quality: A systematic review and meta-analysis.

types: REVIEWThis is an open access article that is freely available in ORE or from the publisher's web site. Please cite the published version.© 2014 The Authors. Published by Elsevier Ltd.Mobile phones are owned by most of the adult population worldwide. Radio-frequency electromagnetic radiation (RF-EMR) from these devices could potentially affect sperm development and function. Around 14% of couples in high- and middle-income countries have difficulty conceiving, and there are unexplained declines in semen quality reported in several countries. Given the ubiquity of mobile phone use, the potential role of this environmental exposure needs to be clarified. A systematic review was therefore conducted, followed by meta-analysis using random effects models, to determine whether exposure to RF-EMR emitted from mobile phones affects human sperm quality. Participants were from fertility clinic and research centres. The sperm quality outcome measures were motility, viability and concentration, which are the parameters most frequently used in clinical settings to assess fertility. We used ten studies in the meta-analysis, including 1492 samples. Exposure to mobile phones was associated with reduced sperm motility (mean difference -8.1% (95% CI -13.1, -3.2)) and viability (mean difference -9.1% (95% CI -18.4, 0.2)), but the effects on concentration were more equivocal. The results were consistent across experimental in vitro and observational in vivo studies. We conclude that pooled results from in vitro and in vivo studies suggest that mobile phone exposure negatively affects sperm quality. Further study is required to determine the full clinical implications for both sub-fertile men and the general population.Open Access funded by Natural Environment Research CouncilJessica

A three-state model with loop entropy for the over-stretching transition
  of DNA

We introduce a three-state model for a single DNA chain under tension that
distinguishes between B-DNA, S-DNA and M (molten or denatured) segments and at
the same time correctly accounts for the entropy of molten loops, characterized
by the exponent c in the asymptotic expression S ~ - c ln n for the entropy of
a loop of length n. Force extension curves are derived exactly employing a
generalized Poland-Scheraga approach and compared to experimental data.
Simultaneous fitting to force-extension data at room temperature and to the
denaturation phase transition at zero force is possible and allows to establish
a global phase diagram in the force-temperature plane. Under a stretching
force, the effects of the stacking energy, entering as a domain-wall energy
between paired and unpaired bases, and the loop entropy are separated.
Therefore we can estimate the loop exponent c independently from the precise
value of the stacking energy. The fitted value for c is small, suggesting that
nicks dominate the experimental force extension traces of natural DNA.Comment: 12 pages, 5 figures + Supplementary informatio
HQET at order 1/m: III. Decay constants in the quenched approximation

We report on the computation of the $B_s$ meson decay constant in Heavy Quark
Effective Theory on the lattice. The next to leading order corrections in the
HQET expansion are included non-perturbatively. We estimate higher order
contributions to be very small. The results are extrapolated to the continuum
limit, the main systematic error affecting the computation is therefore the
quenched approximation used here. The Generalized Eigenvalue Problem and the
use of all-to-all propagators are important technical ingredients of our
approach that allow to keep statistical and systematic errors under control. We
also report on the decay constant $f_{B'_s}$ of the first radially excited
state in the $B_s$ sector, computed in the static limit.Comment: (1+17) pages, 4 figures (7 pdf files); corrected eqn. (3.4),

Tests of a Family Gauge Symmetry Model at 10^3 TeV Scale

Based on a specific model with U(3) family gauge symmetry at $10^3$ TeV
scale, we show its experimental signatures to search for. Since the gauge
symmetry is introduced with a special purpose, its gauge coupling constant and
gauge boson mass spectrum are not free. The current structure in this model
leads to family number violations via exchange of extra gauge bosons. We
investigate present constraints from flavor changing processes and discuss
visible signatures at LHC and lepton colliders.Comment: 12 pages, 2 figures, title changed, minor modification, to appear in
