Violence against women: public health or law enforcement problem or both?
Despite on-going research spanning many years, the police investigation of different forms of violence against women remains under review. The most recent reviews exploring sexual and domestic violence suggest that vulnerable victims are not identified effectively and that this subsequently impacts on the investigation, level of attrition and the provision of correct support for victims. The authors suggest that some of the current methods, aimed at improving these issues, can further compound problems within a police culture that often remains focused on narrow quantifiable performance targets. Violence against women involves a range of very complex issues and for most victims there are a number of vulnerabilities involved.
Considering these factors are often related to public health concerns the authors argue for a more consistent and joined up approach to supporting victims through the Criminal Justice System. In the short term this is necessary for keeping victims on board with the process and in the longer term this is essential when dealing effectively with the broader, longer term issues impacting on their victimisation. It is crucial given the current fiscal climate that these issues are dealt with universally, with a focus on longer term outcomes
Plasmon Evolution and Charge-Density Wave Suppression in Potassium Intercalated Tantalum Diselenide
We have investigated the influence of potassium intercalation on the
formation of the charge-density wave (CDW) instability in 2H-tantalum
diselenide by means of Electron Energy-Loss Spectroscopy and density functional
theory. Our observations are consistent with a filling of the conduction band
as indicated by a substantial decrease of the plasma frequency in experiment
and theory. In addition, elastic scattering clearly points to a destruction of
the CDW upon intercalation as can be seen by a vanishing of the corresponding
superstructures. This is accompanied by a new superstructure, which can be
attributed to the intercalated potassium. Based on the behavior of the c-axis
upon intercalation we argue in favor of interlayer-sites for the alkali-metal
and that the lattice remains in the 2H-modification
Randomised, controlled trial of alternating pressure mattresses compared with alternating pressure overlays for the prevention of pressure ulcers : PRESSURE (pressure relieving support surfaces) trial
Objective To compare whether differences exist between alternating pressure overlays and alternating pressure mattresses in the development of new pressure ulcers, healing of existing pressure ulcers, and patient acceptability. Design Pragmatic, open, multicentre, randomised controlled trial. Setting 11 hospitals in six NHS trusts. Participants 1972 people admitted to hospital as acute or elective patients. Interventions Participants were randomised to an alternating pressure mattress (n = 982) of- an alternating pressure overlay (n = 990). Main outcome measures The proportion of participants developing a new pressure ulcer of grade 2 or worse; time to development of new pressure ulcers; proportions of participants developing a new ulcer within 30 days; healing of existing pressure ulcers; and patient acceptability Results Intention to treat analysis found no difference in the proportions of participants developing a new pressure ulcer of grade 2 or worse (10.7% overlay patients, 10.3% mattress patients; difference 0.4%, 95% confidence interval - 23% to 3.1%, P = 0.75). More overlay patients requested change owing to dissatisfaction (23.3%) than mattress patients (18.9%, P = 0.02). Conclusion No difference was found between alternating pressure mattresses and alternating pressure overlays in the proportion of people who develop a pressure ulcer
Human endogenous retrovirus K106 (HERV-K106) was infectious after the emergence of anatomically modern humans.
HERV-K113 and HERV-K115 have been considered to be among the youngest HERVs because they are the only known full-length proviruses that are insertionally polymorphic and maintain the open reading frames of their coding genes. However, recent data suggest that HERV-K113 is at least 800,000 years old, and HERV-K115 even older. A systematic study of HERV-K HML2 members to identify HERVs that may have infected the human genome in the more recent evolutionary past is lacking. Therefore, we sought to determine how recently HERVs were exogenous and infectious by examining sequence variation in the long terminal repeat (LTR) regions of all full-length HERV-K loci. We used the traditional method of inter-LTR comparison to analyze all full length HERV-Ks and determined that two insertions, HERV-K106 and HERV-K116 have no differences between their 5' and 3' LTR sequences, suggesting that these insertions were endogenized in the recent evolutionary past. Among these insertions with no sequence differences between their LTR regions, HERV-K106 had the most intact viral sequence structure. Coalescent analysis of HERV-K106 3' LTR sequences representing 51 ethnically diverse individuals suggests that HERV-K106 integrated into the human germ line approximately 150,000 years ago, after the emergence of anatomically modern humans
A trio of month long flares in the nova-like variable V704 And
We present the discovery of an unusual set of flares in the nova-like
variable V704 And. Using data from AAVSO, ASAS-SN, and ZTF, of the nova-like
variable V704 And, we have discovered a trio of brightening events that
occurred during the high state. These events elevate the optical brightness of
the source from magnitude to magnitude. The events last
for roughly a month, and exhibit the unusual shape of a slow rise and faster
decay. Just after the third event we obtained data from regular monitoring with
Swift, although by this time the flares had ceased and the source returned to
its pre-flare level of activity in the high-state. The Swift observations
confirm that during the high-state the source is detectable in the X-rays, and
provide simultaneous UV and optical fluxes. As the source is already in the
high-state prior to the flares, and thus the disc is expected to already be in
the high-viscosity state, we conclude that the driver of the variations must be
changes in the mass transfer rate from the companion star and we discuss
possible mechanisms for such short-timescale mass transfer variations to occur.Comment: 5 pages + appendix. Accepted for publication in A&A Letter
