Software Citation in Theory and Practice
In most fields, computational models and data analysis have become a
significant part of how research is performed, in addition to the more
traditional theory and experiment. Mathematics is no exception to this trend.
While the system of publication and credit for theory and experiment (journals
and books, often monographs) has developed and has become an expected part of
the culture, how research is shared and how candidates for hiring, promotion
are evaluated, software (and data) do not have the same history. A group
working as part of the FORCE11 community developed a set of principles for
software citation that fit software into the journal citation system, allow
software to be published and then cited, and there are now over 50,000 DOIs
that have been issued for software. However, some challenges remain, including:
promoting the idea of software citation to developers and users; collaborating
with publishers to ensure that systems collect and retain required metadata;
ensuring that the rest of the scholarly infrastructure, particularly indexing
sites, include software; working with communities so that software efforts
"count" and understanding how best to cite software that has not been
published

Outdoor music festivals: Cacophonous consumption or melodious moderation?
Large outdoor music festivals have emerged as part of a general expansion of licensed recreational activities, but in research terms they have been largely impenetrable due to commercial sensitivities. These sensitivities notwithstanding, the number and scale of such events necessitate a greater understanding of alcohol and drug use and the potential to promote normative protective behaviours in this context. This study examines self-reported alcohol and drug behaviours of 1589 attendees at a music festival in Scotland during the summer of 2008. Similarities between the outdoor rock music festivals and the dance club scene are considered alongside the challenges associated with risk reduction in these settings. Results show that alcohol was consumed by the majority of samples; however, negative consequences were reported by a minority of respondents, suggesting evidence of controlled hedonism within a situation traditionally associated with unrestrained excess. Similarly, the majority of samples did not use drugs. The majority also report a number of self-regulating protective behaviours suggesting that alcohol and drug use is contained within a developing social culture of âcontrolled intoxicationâ. Results further suggest that although music festivals are transitory events, there is a degree of consistency amongst attendees. Music festivals may therefore be atypical but potentially effective environments to increase protective behaviours using normative messaging and modern communications media. This study was resourced exclusively by local alcohol and drug partnerships
International Committee on Mental Health in Cystic Fibrosis: Cystic Fibrosis Foundation and European Cystic Fibrosis Society consensus statements for screening and treating depression and anxiety
Studies measuring psychological distress in individuals with cystic fibrosis (CF) have found high rates of both depression and anxiety. Psychological symptoms in both individuals with CF and parent caregivers have been associated with decreased lung function, lower body mass index, worse adherence, worse health-related quality of life, more frequent hospitalisations and increased healthcare costs. To identify and treat depression and anxiety in CF, the CF Foundation and the European CF Society invited a panel of experts, including physicians, psychologists, psychiatrists, nurses, social workers, a pharmacist, parents and an individual with CF, to develop consensus recommendations for clinical care. Over 18 months, this 22-member committee was divided into four workgroups: Screening; Psychological Interventions; Pharmacological Treatments and
Implementation and Future Research, and used the Population, Intervention, Comparison, Outcome methodology to develop questions for literature search and review. Searches were conducted in PubMed, PsychINFO, ScienceDirect, Google Scholar, Psychiatry
online and ABDATA by a methodologist at Dartmouth. The committee reviewed 344 articles, drafted statements and set an 80% acceptance for each recommendation statement as a consensus threshold prior to an anonymous voting process. Fifteen guideline recommendation statements for screening and treatment of depression and anxiety in individuals with CF and parent caregivers were finalised by vote. As these recommendations are implemented in CF centres internationally, the process of dissemination, implementation and resource provision should be closely monitored to assess barriers and concerns, validity and use
Anxiety, Movement Kinematics, and Visual Attention in Elite-Level Performers
We tested the predictions of Attentional Control Theory (ACT) by examining the effect of anxiety on attention control and the subsequent influence on both performance effectiveness and performance efficiency within a perceptual-motor context. A sample (N = 16) of elite shotgun shooters was tested under counterbalanced low (practice) and high (competition) anxiety conditions. A head-mounted, corneal reflection system allowed point of gaze to be calculated in relation to the scene, while motion of the gun was evaluated using markers placed on the barrel which were captured by two stationary cameras and analyzed using optical tracking software. The quiet eye (QE) duration and onset were analyzed along with gun barrel displacement and variability; performance outcome scores (successful vs. unsuccessful) were also recorded. QE (Vickers, 1996) is defined as the final fixation or tracking gaze that is located on a specific location/object in the visual display for a minimum of 100 ms. Longer QE durations have been linked to successful performance in previous research involving aiming tasks. Participants demonstrated shorter quiet eye durations, and less efficient gun motion, along with a decreased performance outcome (fewer successful trials) under high compared with low anxiety conditions. The data support the predictions of ACT with anxiety disrupting control processes such that goal-directed attention was compromised, leading to a significant impairment in performance effectiveness

Working with prisoners who self-harm: a qualitative study on stress, denial of weakness, and encouraging resilience in a sample of correctional staff
Background: Rates of selfâharm are high among prisoners. Most research focuses on the vulnerable prisoner, and there is little on the impact of these behaviours on staff.
Aims: To investigate staff perceptions of selfâharming behaviours by prisoners, including their views on its causes, manifestation, prevention in institutions, and impact on them.
Methods: Semi-structured interviews were conducted with 20 administrative and 21 therapeutic prison staff who are responsible in various ways for prisoners who selfâharm. Their narratives were explored using interpretative phenomenological analysis.
Results: Despite prison staff being experienced with prisoners' selfâharming behaviours, including severe acts of selfâharm, they were apt to reject any negative impact on their own mental health or wellâbeing. This denial of negative impact was accompanied by perceptions of the inmate's actions being manipulative and attention seeking. Prison staff also perceived institutional responses to selfâharming behaviours by prisoners as being mixed, ambiguous, or showing preference for relying on existing suicide protocols rather than taskâspecific guidance.
Conclusions: Although staff gave explanations of prisoner selfâharm in terms of âmanipulative behaviourâ, prisoners' selfâharm is, in fact, complex, challenging, and often severe. This staff perception may reflect denial of impact of often distressing behaviours on them personally and their own coping mechanisms. This could be feeding in to a perceived lack of clear and effective institutional responses to the selfâharm, so further research is needed to determine how staff could broaden their views, and respond more effectively to prisoners. Psychologically informed group work and/or reflective practice are among the candidates for such help for staff
Childhood injury in Tower Hamlets: Audit of children presenting with injury to an inner city A&E department in London.
Childhood injury is a leading cause of mortality and morbidity worldwide with the most socio-economically deprived children at greatest risk. Current routine NHS hospital data collection in England is inadequate to inform or evaluate prevention strategies. A pilot study of enhanced data collection was conducted to assess the feasibility of collecting accident and emergency data for national injury surveillance
Photosynthesis dependent acidification of perialgal vacuoles in theParamedum bursaria/Chlorella symbiosis. Visualization by monensin
After treatment with the carboxylic ionophore monensin theChlorella containing perialgal vacuoles of the greenParamecium bursaria swell. TheParamecium cells remain motile at this concentration for at least one day. The swelling is only observed in illuminated cells and can be inhibited by DCMU. We assume that during photosynthesis the perialgal vacuoles are acidified and that monensin exchanges H+ ions against monovalent cations (here K+). In consequence the osmotic value of the vacuoles increases. The proton gradient is believed to drive the transport of maltose from the symbiont into the host. Another but light independent effect of the monensin treatment is the swelling of peripheral alveoles of the ciliates, likewise indicating that the alveolar membrane contains an active proton pump
AI Researchers, Video Games Are Your Friends!
If you are an artificial intelligence researcher, you should look to video
games as ideal testbeds for the work you do. If you are a video game developer,
you should look to AI for the technology that makes completely new types of
games possible. This chapter lays out the case for both of these propositions.
It asks the question "what can video games do for AI", and discusses how in
particular general video game playing is the ideal testbed for artificial
general intelligence research. It then asks the question "what can AI do for
video games", and lays out a vision for what video games might look like if we
had significantly more advanced AI at our disposal. The chapter is based on my
keynote at IJCCI 2015, and is written in an attempt to be accessible to a broad
audience.Comment: in Studies in Computational Intelligence Studies in Computational
