Learning spillover and analogy-based expectations: a multi-game experiment
We consider a multi-game interactive learning environment and ask ourselves
whether long run behaviors in one game are a¤ected by behaviors in the other,
i.e whether there are learning spillovers. Our main �nding is that learning
spillovers arise whenever the feedback provided to subjects about past play is
not easily accessible game by game and thus subjects get a more immediate
impression about aggregate distributions. In such a case, long run behaviors
stabilize to an analogy-based expectation equilibrium (Jehiel 2005), thereby
suggesting how one should broaden the notion of equilibrium to cope with
learning spillovers
Disposable labour, passive victim, active threat: migrant/non-migrant othering in three British television documentaries
This article analyses discourses about migration within three documentaries that were broadcast on terrestrial British television in January 2014: The Truth about Immigration in the UK and The Hidden World of Britain’s Immigrants, both broadcast on BBC 2, and Episode 2 of Benefits Street, broadcast on Channel 4. The methodology involved a detailed analysis of the documentaries, situated within a Marxist analysis of British capitalism, the capitalist crisis, and the economic and political position of migrants. Amidst the contradictions and complexities that were identified within these documentaries, representations of 'migrants' can be grouped into three categories: disposable labour; passive victim; and active threat. We argue these discursive roles reflect and reinforce capitalist exploitation, by constructing 'migrants' as a mutable 'other' to divide the working class
Nanoengineering Carbon Allotropes from Graphene
Monolithic structures can be built into graphene by the addition and
subsequent re-arrangement of carbon atoms. To this end, ad-dimers of carbon are
a particularly attractive building block because a number of emerging
technologies offer the promise of precisely placing them on carbon surfaces. In
concert with the more common Stone-Wales defect, repeating patterns can be
introduced to create as yet unrealized materials. The idea of building such
allotropes out of defects is new, and we demonstrate the technique by
constructing two-dimensional carbon allotropes known as haeckelite. We then
extend the idea to create a new class of membranic carbon allotropes that we
call \emph{dimerite}, composed exclusively of ad-dimer defects.Comment: 5 pages, 5 figure
The Effects of Negative Legacies on the Adjustment of Parentally Bereaved Children and Adolescents
This is a report of a qualitative analysis of a sample of bereaved families in which one parent died and in which children scored in the clinical range on the Child Behavior Check List. The purpose of this analysis was to learn more about the lives of these children. They were considered to be at risk of developing emotional and behavioral problems associated with the death. We discovered that many of these “high risk” children had a continuing bond with the deceased that was primarily negative and troubling for them in contrast to a comparison group of children not at risk from the same study. Five types of legacies, not mutually exclusive, were identified: health related, role related, personal qualities, legacy of blame, and an emotional legacy. Coping behavior on the part of the surviving parent seemed to make a difference in whether or not a legacy was experienced as negative
Cultural basis of social ‘deficits’ in autism spectrum disorders
There is very little research that specifically looks at how autism spectrum disorders are perceived in various communities. This qualitative research was conducted with parents who had children on the autistic spectrum belonging to four different ethnic communities (White British, Somali, West African and South Asian- 63 in total) and living in the UK. The study found that the importance that the parents give to various social skills varied on the basis of their cultural background and the gender of the parent. This is an important aspect to consider while providing support and services to individuals on the autism spectrum and their family members if the services have to be appropriate for their needs. This consideration would also enable the individuals on the autism spectrum to develop appropriate social skills required within their cultural groups. This is a preliminary study and further research on the topic is required
Cubic Augmentation of Planar Graphs
In this paper we study the problem of augmenting a planar graph such that it
becomes 3-regular and remains planar. We show that it is NP-hard to decide
whether such an augmentation exists. On the other hand, we give an efficient
algorithm for the variant of the problem where the input graph has a fixed
planar (topological) embedding that has to be preserved by the augmentation. We
further generalize this algorithm to test efficiently whether a 3-regular
planar augmentation exists that additionally makes the input graph connected or
biconnected. If the input graph should become even triconnected, we show that
the existence of a 3-regular planar augmentation is again NP-hard to decide.Comment: accepted at ISAAC 201
Health economic assessment tools (HEAT) for walking and for cycling
Physical inactivity is a significant public health
problem in most regions of the world, which
is unlikely to be solved by classical health
promotion approaches alone. The promotion
of active transport (cycling and walking) for
everyday physical activity is a win-win approach;
it not only promotes health but can also lead
to positive environmental effects, especially
if cycling and walking replace short car trips.
Cycling and walking can also be more readily
integrated into people’s busy schedules than,
for example, leisure-time exercise. These forms
of physical activity are also more practicable for
groups of the population for which sport is either
not feasible because of physical limitations or is
not an accessible leisure activity for economic,
social or cultural reasons. There is a large
potential for active travel in European urban
transport, as many trips are short and would
be amenable to being undertaken on foot or
by bicycle. This, however, requires effective
partnerships with the transport and urban
planning sectors, whose policies are key driving
forces in providing appropriate conditions for
such behavioural changes to take place. This has
been recognized by a number of international
policy frameworks, such as the Action Plan for
implementation of the European Strategy for the
Prevention and Control of Noncommunicable
Diseases 2012–2016, adopted by the WHO
Regional Committee for Europe (1). The strategy
identifies the promotion of active mobility as
one of the supporting interventions endorsed
by WHO Member States to address this highpriority
topic in the European Region, as do other
international policy frameworks such as the
Toronto Charter for Physical Activity launched
in May 2010 as a global call for action (2)
Early risk factors for adolescent antisocial behaviour: an Australian longitudinal study
Objective: This investigation utilizes data from an Australian longitudinal study to identify early risk factors for adolescent antisocial behaviour. Method: Analyses are based on data from the Mater University Study of Pregnancy, an on-going longitudinal investigation of women’s and children’s health and development involving over 8000 participants. Five types of risk factors (child characteristics, perinatal factors, maternal/familial characteristics, maternal pre- and post-natal substance use and parenting practices) were included in analyses and were based on maternal reports, child assessments and medical records. Adolescent antisocial behaviour was measured when children were 14 years old, using the delinquency subscale of the Child Behaviour Checklist. Results: Based on a series of logistic regression models, significant risk factors for adolescent antisocial behaviour included children’s prior problem behaviour (i.e. aggression and attention/restlessness problems at age 5 years) and marital instability, which doubled or tripled the odds of antisocial behaviour. Perinatal factors, maternal substance use, and parenting practices were relatively poor predictors of antisocial behaviour. Conclusions: Few studies have assessed early predictors of antisocial behaviour in Australia and the current results can be used to inform prevention programs that target risk factors likely to lead to problem outcomes for Australian youth
Pharmacists in Pharmacovigilance: Can Increased Diagnostic Opportunity in Community Settings Translate to Better Vigilance?
The pharmacy profession has undergone substantial change over the last two to three decades. Whilst medicine supply still remains a central function, pharmacist’s roles and responsibilities have become more clinic and patient focused. In the community (primary care), pharmacists have become important providers of healthcare as Western healthcare policy advocates patient self-care. This has resulted in pharmacists taking on greater responsibility in managing minor illness and the delivery of public health interventions. These roles require pharmacists to more fully use their clinical skills, and often involve diagnosis and therapeutic management. Community pharmacists are now, more than ever before, in a position to identify, record and report medication safety incidents. However, current research suggests that diagnostic ability of community pharmacists is questionable and they infrequently report to local or national schemes. The aim of this paper is to highlight current practice and suggest ways in which community pharmacy can more fully contribute to patient safety
Adolescent self-control predicts midlife hallucinatory experiences:40-year follow-up of a national birth cohort
Associations between self-control in adolescence and adult mental health are unclear in the general population; to our knowledge, no study has investigated self-control in relation to psychotic-like symptoms
