Prospects for India's cereal supply and demand to 2020:
The possibility of an emerging cereal gap of serious proportions by the year 2020, is a useful illustration of the kind of constructive dialogue IFPRI hopes to encourage. It responds to several quite recent developments, notably the rapid expansion of India's industrial and service sectors since the 1991 structural reforms, the improved prospects for continued growth over the next few decades, and the likelihood of rising per capita incomes that could generate substantially increased demand for livestock products. As demand for livestock products grows, livestock production could increasingly depend on cereals for feed — perhaps as much as 50 million tons by 2020, according to G.S. Bhalla, Peter Hazell, and John Kerr, authors of this 2020 discussion paper on Prospects for Balancing Cereal Needs in India to 2020. These conclusions differ somewhat from other IFPRI studies, which have generally found that growth in demand for livestock products will be lower than the current study. This divergence of views is a useful signal to policymakers to pay careful attention to trends in demand for livestock products in India in the coming years. This study and the rest of IFPRI's 2020 research have consistently pointed to the vital link between agricultural policies and prospects for production growth in the next two decades.

On the interpretation of lateral manganin gauge stress measurements in polymers
Encapsulated wire-element stress gauges enable changes in lateral stress during
shock loading to be directly monitored. However, there is substantial debate
with regards to interpretation of observed changes in stress behind the shock
front; a phenomenon attributed both to changes in material strength and shock-
dispersion within the gauge-encapsulation. Here, a pair of novel techniques
which both modify or remove the embedding medium where such stress gauges are
placed within target materials have been used to try and inform this debate. The
behavior of three polymeric materials of differing complexity was considered,
namely polystyrene, the commercially important resin transfer moulding RTM 6
resin and a commercially available fat lard. Comparison to the response of
embedded gauges has suggested a possible slight decrease in the absolute
magnitude of stress. However, changing the encapsulation has no detectable
effect on the gradient behind the shock in such polymeric systems
Is doing a PhD bad for your mental health?
Poor mental health amongst PhD researchers is increasingly being recognised as an issue within higher education institutions. However, there continues to be unanswered questions relating to the propensity and causality of poor mental health amongst PhD researchers. Reporting on a new comparative survey of PhD researchers and their peers from different professions, Dr Cassie M Hazell and Dr Clio Berry find that PhD researchers are particularly vulnerable to poor mental health compared to their peers. Arguing against an inherent and individualised link between PhD research and mental health, they suggest institutions have a significant role to play in reviewing cultures and working environments that contribute to the risk of poor mental health
Modelling and characterization of cell collapse in aluminium foams during dynamic loading
Plate-impact experiments have been conducted to investigate the elastic–plastic behaviour of shock wave propagation and pore collapse mechanisms of closed-cell aluminium foams. FE modelling using a meso-scale approach has been carried out with the FE software ABAQUS/Explicit. A micro-computed tomography-based foam geometry has been developed and microstructural changes with time have been investigated to explore the effects of wave propagation. Special attention has been given to the pore collapse mechanism. The effect of velocity variations on deformation has been elucidated with three different impact conditions using the plate-impact method. Free surface velocity (ufs) was measured on the rear of the sample to understand the evolution of the compaction. At low impact velocities, the free-surface velocity increased gradually, whereas an abrupt rise of free-surface velocity was found at an impact velocity of 845 m/s with a copper flyer-plate which correlates with the appearance of shock. A good correlation was found between experimental results and FE predictions
Pilot evaluation of a brief training video aimed at reducing mental health stigma amongst emergency first responders (the ENHANcE II study)
Background
First responders (i.e. police and ambulance staff) have increasingly become part of the mental health care system, often being the first port of call for those experiencing a crisis. Despite their frequent involvement in supporting those with mental health problems, there is evidence that mental health stigma is high amongst first responders.
Aims
The aim of the present study was to evaluate a brief training video aimed at reducing mental health stigma amongst first responders.
Methods
First responders watched a training video based on the cognitive behavioural model of mental health stigma, and involved contributions from people with lived experience, and first responders. Measures of mental health stigma were collected before and after viewing the training.
Results
The training video produced small but significant improvements in mental health stigma, and these effects did not differ between police and ambulance staff. We were unable to determine what psychological constructs mediated this change in stigma. The feedback on the training video was generally positive, but also indicated some key areas for future development.
Conclusions
The present study provides encouraging evidence that levels of mental health stigma can be improved using a resource-light training intervention
Creating a hierarchy of mental health stigma: testing the effect of psychiatric diagnosis on stigma
Systemic Risk-Shifting in Financial Networks
Banks face different but potentially correlated risks from outside the financial system. Financial connections can share these risks, but also create the means by which shocks can propagate. We examine this tradeoff in the context of a new stylised fact
Guided self-help cognitive behavioral intervention for VoicEs (GiVE): study protocol for a pilot randomized controlled trial
Background: Cognitive behavior therapy for psychosis (CBTp) is an effective intervention for people who hear distressing voices (auditory hallucinations). However, there continues to be a problem of poor access to CBTp. Constraints on health care funding require this problem to be addressed without a substantial increase in funding. One solution is to develop guided self-help forms of CBTp to improve access, and a symptom-specific focus on, for example, distressing voices (auditory verbal hallucinations) has the potential to enhance effectiveness. We term this cognitive behavior therapy for distressing voices (CBTv).
Methods/design: This trial is an external pilot randomized controlled trial comparing the effects of 12 week guided self-help CBTv (with eight therapist support sessions) with a wait list control condition. Informed consent will be obtained from each participant. Half of the 30 participants will be randomized to receive guided self-help CBTv immediately; the remaining half will receive the intervention after a 12-week delay. All participants will continue with their usual treatment throughout the study. Outcomes will be assessed using questionnaires completed at baseline and 12 weeks postrandomization. Interviews will be offered to all those who receive therapy immediately to explore their experiences with the intervention.
Discussion: The outcomes of this trial, both quantitative and qualitative, will inform the design of a definitive randomized controlled trial of guided self-help CBTv. If this intervention is effective, it could help to increase access to CBT for those who hear distressing voices
A Systematic Review of the Effects of Urban Living on Suicidality and Self-Harm in the UK and Ireland
We conducted a systematic review to answer the following: (a) Is there any evidence to support increased prevalence of suicidality and self-harm (i.e. self-harm or suicidality) in urban versus rural environments? (b) What aspects of the urban environment pose risk for suicidality and self-harm? Thirty-five studies met our criteria. Our findings reflect a mixed picture, but with a tendency for urban living to be associated with an increased risk of suicidality and self-harm over rural living, particularly for those living in deprived areas. Further research should focus on the clustering and additive effects of risk and protective factors for suicidality and self-harm in urban environments
