An examination of the factors that influence the publication or non-publication of mental health nursing research presented at national or international nursing conferences
Mental health nurses are required to be able to identify and access the current evidence surrounding a particular topic and evaluate and decide upon the best care approach to people with mental health problems. This is aided by specific guidance on how to facilitate access to and deliver the best quality evidence-based care. This is most commonly acquired by accessing evidence through hand searching publications or through electronic sources (databases, web search engines or internet publications).
However, evidence indicates that only a small proportion of mental health nursing research is published and that many nurses carry out research that is not published. Although, it is difficult to judge the quality of unpublished research the likelihood is that a number of high quality mental health nursing research projects are not published and are therefore not available to be evaluated as part of the evidence base of care. There has been relatively little examination of the reasons underpinning publication of nursing research.
This project examined the factors that influence the publication or non-publication of mental health nursing research presented at national or international nursing conferences in the UK

Antarctic subglacial hydrology: current knowledge and future challenges
AbstractFlood-carved landforms across the deglaciated terrain of Victoria Land, East Antarctica, provide convincing geomorphological evidence for the existence of subglacial drainage networks beneath the Antarctic ice sheet, and motivate research into the inaccessible environment beneath the contemporary ice sheet. Through this research, our understanding of Antarctic subglacial hydrology is steadily building, and this paper presents an overview of the current state of knowledge. The conceptualization of subglacial hydrological behaviour was developed at temperate and Arctic glaciers, and is thus less mature in the Antarctic. Geophysical and remote sensing observations have demonstrated that many subglacial lakes form part of a highly dynamic network of subglacial drainage beneath the Antarctic ice sheet. Recent research into subglacial water flows, other than those directly concerned with lakes, has discovered potentially significant impacts on ice stream dynamics, ice sheet mass balance, and supplies of water to the ocean potentially affecting circulation and nutrient productivity. Despite considerable advances in understanding there remain a number of grand challenges that must be overcome in order to improve our knowledge of these subglacial hydrological processes.</jats:p
The State of Solutions for Autonomous Systems Safety
Autonomous Systems are seeing increasing use and increasingly safety-significant application. Consequently, the safety of autonomous systems is an important topic. To reflect this importance the Safety Critical Systems Club (SCSC) has established the Safety of Autonomous Systems Working Group (SASWG). This paper introduces the SASWG and describes (and justifies) the approach it is taking. A running example is used to illustrate challenges, which are organised against three “difficulty horizons”. Potential solutions to some of the challenges are outlined; possible research directions are suggested for other challenges. Some proposed but invalid solutions are also identified. Overall, whilst the SASWG acknowledges the very significant benefits that could accrue from autonomous systems, it believes their development and implementation should be pursued carefully and thoughtfully
Do Unemployment Insurance Recipients Actively Seek Work? Evidence From Randomized Trials in Four U.S. States
In this paper we report the results of the only field test of which we are aware that uses
randomized trials to measure whether stricter enforcement and verification of work search
behavior alone decreases unemployment claims and benefits paid in the U.S.
unemployment insurance (UI) program. These experiments, which we implemented in four
sites in Connecticut, Massachusetts, Virginia, and Tennessee, were designed to explicitly
test claims based on nonexperimental data, summarized in Burgess and Kingston (1987),
that a prime cause of overpayments is the failure of claimants to actively seek work. Our
results provide no support for the view that the failure to actively search for work has been a
cause of overpayments in the UI system
Dust in Interstellar Clouds, Evolved Stars and Supernovae
Outflows of pre-main-sequence stars drive shocks into molecular material
within 0.01 - 1 pc of the young stars. The shock-heated gas emits infrared,
millimeter and submillimeter lines of many species including. Dust grains are
important charge carriers and play a large role in coupling the magnetic field
and flow of neutral gas. Some effects of the dust on the dynamics of oblique
shocks began to emerge in the 1990s. However, detailed models of these shocks
are required for the calculation of the grain sputtering contribution to gas
phase abundances of species producing observed emissions. We are developing
such models. Some of the molecular species introduced into the gas phase by
sputtering in shocks or by thermally driven desorption in hot cores form on
grain surfaces. Recently laboratory studies have begun to contribute to the
understanding of surface reactions and thermally driven desorption important
for the chemistry of star forming clouds. Dusty plasmas are prevalent in many
evolved stars just as well as in star forming regions. Radiation pressure on
dust plays a significant role in mass loss from some post-main-sequence stars.
The mechanisms leading to the formation of carbonaceous dust in the stellar
outflows are similar to those important for soot formation in flames. However,
nucleation in oxygen-rich outflows is less well understood and remains a
challenging research area. Dust is observed in supernova ejecta that have not
passed through the reverse shocks that develop in the interaction of ejecta
with ambient media. Dust is detected in high redshift galaxies that are
sufficiently young that the only stars that could have produced the dust were
so massive that they became supernovae. Consequently, the issue of the survival
of dust in strong supernova shocks is of considerable interest.Comment: 4 pages, to be published in the proceedings of Fifth International

Topological G 2 and Spin(7) strings at 1-loop from double complexes
© The Authors. Article funded by SCOAP3. This article is distributed under the terms of the Creative Commons Attribution License (CC-BY 4.0), https://creativecommons.org/licenses/by/4.0/We study the topological G2 and Spin(7) strings at 1-loop. We define new double complexes for supersymmetric NSNS backgrounds of string theory using generalised geometry. The 1-loop partition function then has a target-space interpretation as a particular alternating product of determinants of Laplacians, which we have dubbed the analytic torsion. In the case without flux where these backgrounds have special holonomy, we reproduce the worldsheet calculation of the G2 string and give a new prediction for the Spin(7) string. We also comment on connections with topological strings on Calabi-Yau and K3 backgrounds.Peer reviewedFinal Published versio
