How accurate and useful are published UK prevalence rates of intimate partner violence (IPV)? Rapid review and methodological commentary

Purpose This paper aims to estimate the prevalence of intimate partner violence (IPV) in the UK general population and in the low-risk clinical population and to identify the methodological challenges presented by this task. Design/methodology/approach A rapid review of the evidence was conducted. Data were extracted with the help of pre-designed tools and were synthesised to answer the two study aims. The data extracted was both qualitative and quantitative. Findings In the general population, crime survey data gave a range of past-year IPV prevalence from 1.8% to 4.5%. This was higher in women than men (2.5%–6.3% vs 0.9%–2.7%). In both the general and low-risk clinical population, there was little data on pregnant women or gay men and lesbians. No significant relationships between IPV and ethnicity were found. Different surveys used different definitions of IPV and domestic violence, making it difficult to give an accurate estimate. There were also problems with data accuracy. Originality/value This research is original and contributes to the knowledge about IPV screening and if prevalence studies help

Precision Lunar Laser Ranging For Lunar and Gravitational Science

Laser ranging to retroreflector arrays placed on the lunar surface by the Apollo astronauts and the Soviet Lunar missions over the past 39 years have dramatically increased our understanding of gravitational physics along with Earth and Moon geophysics, geodesy, and dynamics. Significant advances in these areas will require placing modern retroreflectors and/or active laser ranging systems at new locations on the lunar surface. Ranging to new locations will enable better measurements of the lunar librations, aiding in our understanding of the interior structure of the moon. More precise range measurements will allow us to study effects that are too small to be observed by the current capabilities as well as enabling more stringent tests of Einstein's theory of General Relativity. Setting up retroreflectors was a key part of the Apollo missions so it is natural to ask if future lunar missions should include them as well. The Apollo retroreflectors are still being used today, and nearly 40 years of ranging data has been invaluable for scientific as well as other studies such as orbital dynamics. However, the available retroreflectors all lie within 26 degrees latitude of the equator, and the most useful ones within 24 degrees longitude of the sub-earth meridian. This clustering weakens their geometrical strength

How accurate and effective are screening tools and subsequent interventions for intimate partner violence in non-high-risk settings (IPV)? A rapid review

Purpose The purpose of this paper is to estimate the accuracy and effectiveness of screening tools and subsequent interventions in the detection and treatment of intimate partner violence (IPV) in non-high-risk settings (defined here as those in which routine IPV screening does not take place in the UK, such as in general practice). Design/methodology/approach Rapid review as defined by Grant and Booth – it is used under time or financial constraint to assess what is known using systematic review methods. Medline, PsycINFO, Embase and Cochrane Library databases to May 2019 were searched for “intimate partner violence” and synonyms plus terms related to screening and interventions. A Medline update was performed in August 2020. Data were extracted with the help of a predesigned tool and were synthesised to answer the two study aims. Data were mixed quantitative and qualitative. Findings The search yielded 10 relevant papers on screening (6 on accuracy and 4 on effectiveness) and 13 on intervention. These showed evidence of the effectiveness of simple screening tools and of subsequent interventions. However, the evidence was insufficient to support a change in UK guidelines which currently do not recommend their use outside of current high-risk environments. Originality/value Clinicians outside of high-risk areas should consider the use of some IPV screening tools and interventions but only within research protocols to gather further evidence

The Acclaim Programme in the South Atlantic and Southern Oceans

The ACCLAIM sea level network consists of six coastal tide gauge sites and approximately a dozen bottom pressure stations in the South Atlantic and Southern Oceans. Since 1985, an extensive dataset of regional sea level and bottom pressure measurements has been acquired. This dataset is being employed at POL in a number of scientific analyses and is available to any interested research worker through the World Ocean Circulation Experiment. In this paper, a review is given of the development and status of the ACCLAIM network and the technology installed at each site. Plans are presented for developments over the next 1-2 years

Interpersonal dynamics in baseline rallies in tennis

In tennis, the relative positioning of players on court constrains their opportunities to perform successful actions. In this study we proposed and validated an empirical function that captures the spatial-temporal relationship between tennis players during competitive performance. This parameter, termed goal-directed displacement index (GDD Index), is defined over time by the product of both players' distances to the central line of the court and to the centre of the net. Results showed that the GDD index successfully described tennis players' patterns of interaction, as well as identified breaks in patterns of play during competitive performance, due to changes in relative positioning on court. Our analysis revealed two different patterns of interpersonal interactions, cross and down-the-line rallies, and two ways for a break to emerge in game dynamics, parallel variation (transition from a cross court rally to a down-the-line rally) and angle opening (lateral displacement). Data suggest that the elaboration of specific individual profiles of performance for different players, using the GDD index, could improve performance analysis in tennis

Tissue mimicking materials for imaging and therapy phantoms: a review

Tissue mimicking materials (TMMs), typically contained within phantoms, have been used for many decades in both imaging and therapeutic applications. This review investigates the specifications that are typically being used in development of the latest TMMs. The imaging modalities that have been investigated focus around CT, mammography, SPECT, PET, MRI and ultrasound. Therapeutic applications discussed within the review include radiotherapy, thermal therapy and surgical applications. A number of modalities were not reviewed including optical spectroscopy, optical imaging and planar x-rays. The emergence of image guided interventions and multimodality imaging have placed an increasing demand on the number of specifications on the latest TMMs. Material specification standards are available in some imaging areas such as ultrasound. It is recommended that this should be replicated for other imaging and therapeutic modalities. Materials used within phantoms have been reviewed for a series of imaging and therapeutic applications with the potential to become a testbed for cross-fertilization of materials across modalities. Deformation, texture, multimodality imaging and perfusion are common themes that are currently under development
