Accidental injury, risk-taking behaviour and the social circumstances in which young people (aged 12-24) live: a systematic review
In industrialised countries such as England and Wales, unintended injury (which ranges from sprains in sport to hospitalisation and death due to drugs or transport crashes) is the leading cause of death in children aged 0 to 14 years, and a major cause of death in young adults aged 15 to 24. It is also a major cause of ill health and disability in these age groups. There is a large body of research on young people and their perceived propensity to take risks. Common sense suggests that an increased willingness to place oneself at risk will result an increased likelihood of physical injury. However, given that pathways to injury are complex and not always well understood, the UK Department of Health commissioned a large systematic review to examine this multifaceted issue.
Drug use
• The review found that the use of drugs is associated with an increased risk of accidental death among young people and that 12–24 year olds are less at risk than those immediately older. However, risk of death increases with length of drug use, so there is value in targeting interventions at this age group.
• Many more young men than women die from drug overdoses, because more men take drugs, but those women who do use drugs are at higher risk. Certain other groups of young people are more at risk than others. These include young people in deprived areas and men who have recently been released from prison.
• There was a clear disjunction of views between young people who used drugs and those who did not. The young people who did not take drugs regarded them as risky and stated that media images about possible negative consequences dissuaded them from trying them, while those who did tended not to believe ‘official’ messages about possible harms and did not perceive taking drugs as being dangerous. Cannabis in particular was singled out as possibly being good for you, with some young people believing it to be cheaper than alcohol. The recent reclassification of cannabis and the subsequent debate may have helped to reinforce this view.
• The burden of the more serious injuries – as demonstrated by the mortality statistics – is carried by young people in the lower socio-economic groups.
• In road injuries, drugs are found in the bloodstream of more young fatal accident victims than older age groups; however, it is difficult to assess whether drugs actually contributed to the accident.
• Driving on cannabis was thought to be more acceptable than drink-driving and not thought to be dangerous.
Alcohol use
• Almost everyone admitted to hospital for alcohol poisoning is aged between 11 and 17. After a sharp peak among 14 and 15 year olds, hospital admissions for injuries with alcohol involvement decline slowly between the ages of 16 and 30.
• Correlational studies have shown that alcohol puts the drinker at an increased risk of injury, that young people are more likely to have injuries than older people, and that young men are more at risk than young women. In the one study that examined ethnicity, minority ethnic status did not increase alcohol-related injuries, and may in fact have had a protective association.
• Views studies found that young people say that they do not commonly mix alcohol and other drugs. Most young people reported that drinking places them at greater risk of injury, though some did not. The younger teenagers – 14 and 15 year olds – felt most in danger of injury when drinking. Young people felt that they learned to manage their drinking through experience and that unsupervised, outdoor drinking was the most dangerous and was more common among younger teenagers (with injuries being considered less common in licensed venues). Peers encourage both drinking and drunken pranks, but also protect one another when they have become more vulnerable as a result of drink. Young people felt that drinking reduces their perceptions of danger and some stated that injury as a result was inevitable. Most young people were cautious about getting very drunk, though being sick as a result of drinking is common and not regarded as serious. Bad experiences – whether to self or someone else – might change behaviour in the short- but not long-term.
• One study which examined attempts to reduce alcohol-related injuries found some evidence that motivational interviews in A&E departments are more effective than information handouts.
Drink-driving
• Drink-driving was generally considered dangerous and not socially acceptable, whereas driving on cannabis was more acceptable and not thought to be dangerous. Some young people stated that a lack of public transport (or alternatives, such as taxis) made it more likely that they would drink and drive.
• Interventions based on models of behaviour change to reduce drink-driving are ineffective or have a negative effect. Combining different approaches has more effect than using a single approach. Education or skills training has either negative or no effects on driver behaviour and subsequent accidents, possibly because these approaches lead to over-confidence or early licensing.
• Legislation and enforcement on reducing drink-driving has been found to be effective
An Extinction Threshold for Protostellar Cores in Ophiuchus
We have observed continuum emission at lambda = 850 microns over ~4 square
degrees of the Ophiuchus star-forming cloud using SCUBA on the JCMT, producing
a submillimetre continuum map twenty times larger than previous Ophiuchus
surveys. Our sensitivity is 40 mJ/beam, a factor of ~2 less sensitive than
earlier maps. Using an automated identification algorithm, we detect 100
candidate objects. Only two new objects are detected outside the boundary of
previous maps, despite the much wider area surveyed. We compare the
submillimetre continuum map with a map of visual extinction across the
Ophiuchus cloud derived using a combination of 2MASS and R-band data. The total
mass in submillimetre objects is ~ 50 Msun compared with ~ 2000 Msun in
observed cloud mass estimated from the extinction. The submillimetre objects
represent only 2.5% of the cloud mass. A clear association is seen between the
locations of detected submillimetre objects and high visual extinction, with no
objects detected at A_V<7 magnitudes. Using the extinction map, we estimate
pressures within the cloud from P/k ~2x10^5 cm^-3 K in the less-extincted
regions to P/k ~2x10^6 cm^-3 K at the cloud centre. Given our sensitivities,
cold (T_d ~15K) clumps supported by thermal pressure, had they existed, should
have been detected throughout the majority of the map. Such objects may not be
present at low A_V because they may form only where A_V > 15, by some mechanism
(e.g., loss of non-thermal support).Comment: 12 pages, 1 figure. Accepted by Astrophysical Journal Letter
Active Region Moss: Doppler Shifts from Hinode/EIS Observations
Studying the Doppler shifts and the temperature dependence of Doppler shifts
in moss regions can help us understand the heating processes in the core of the
active regions. In this paper we have used an active region observation
recorded by the Extreme-ultraviolet Imaging Spectrometer (EIS) onboard Hinode
on 12-Dec-2007 to measure the Doppler shifts in the moss regions. We have
distinguished the moss regions from the rest of the active region by defining a
low density cut-off as derived by Tripathi et al. (2010). We have carried out a
very careful analysis of the EIS wavelength calibration based on the method
described in Young et al. (2012). For spectral lines having maximum sensitivity
between log T = 5.85 and log T = 6.25 K, we find that the velocity distribution
peaks at around 0 km/s with an estimated error of 4-5 km/s. The width of the
distribution decreases with temperature. The mean of the distribution shows a
blue shift which increases with increasing temperature and the distribution
also shows asymmetries towards blue-shift. Comparing these results with
observables predicted from different coronal heating models, we find that these
results are consistent with both steady and impulsive heating scenarios.
However, the fact that there are a significant number of pixels showing
velocity amplitudes that exceed the uncertainty of 5 km s is suggestive
of impulsive heating. Clearly, further observational constraints are needed to
distinguish between these two heating scenarios.Comment: 21 pages (single column), 7 figures, Accepted for Publication in The

The Assassination Of Lord Mayo: The 'first' Jihad?
In February 1872, Lord Mayo, Governor-General of India, was assassinated at
the penal settlement of Port Blair in the Andaman Islands whilst paying a viceregal visit to the Province of British Burma. His assassin, a Pathan from North
West India who had been in the Peshawar police, made no attempt to escape. He
had been serving a life sentence for murder, a murder of which he had declared
himself 'Not Guilty'. The manuscripts and papers relating to the thorough
investigation that was immediately launched into the death of the Viceroy use the
word jihad ('struggle for the Faith') to explain the motivation for the
assassination. However, intriguing unanswered questions remain that this paper
will attempt to highlight. Was the alleged assassin a mere tool in a larger game
of world politics? Was Lord Mayo's security detail deliberately slack in
performing its duties? Based on the manuscript collections in the Cambridge
University Library, this paper scrutinises the evidence and frames it within the
colonial history of the loss of Burmese independence in three wars with Britain
from 1824 to 1885
