Payoff levels, loss avoidance, and equilibrium selection in the Stag Hunt: an experimental study

Game theorists typically assume that changing a game’s payoff levels—by adding the same constant to, or subtracting it from, all payoffs—should not affect behavior. While this invariance is an implication of the theory when payoffs mirror expected utilities, it is an empirical question when the “payoffs” are actually money amounts. In particular, if individuals treat monetary gains and losses differently, then payoff–level changes may matter when they result in positive payoffs becoming negative, or vice versa. We report the results of a human–subjects experiment designed to test for two types of loss avoidance: certain–loss avoidance (avoiding a strategy leading to a sure loss, in favor of an alternative that might lead to a gain) and possible–loss avoidance (avoiding a strategy leading to a possible loss, in favor of an alternative that leads to a sure gain). Subjects in the experiment play three versions of Stag Hunt, which are identical up to the level of payoffs, under a variety of treatments. We find differences in behavior across the three versions of Stag Hunt; these differences are hard to detect in the first round of play, but grow over time. When significant, the differences we find are in the direction predicted by certain– and possible–loss avoidance. Our results carry implications for games with multiple equilibria, and for theories that attempt to select among equilibria in such games.

On the safe of pesticides in controlling the terrestrial mollusc pests

The preferred food items of the slugs Laevicaulis alte and the snails Achatina fulica were used to prepare 'poison baits'by injecting the pesticides 'Rogor'and 'Nuvan'to kill these mollusc pests. The 'poison baits'prepared with Thrichosanthes dioica and Lycopersicum esculentum were accepted by 100% individuals of both the species irrespective of the pesticides used. In all cases the slug and the snail individuals died within a considerable length of time following consuption of the bait. The importance of using 'poison bait'lies not only with the sure success in killing the pests but also with the 'safe use'of toxic materials in order to avoid environmental hazards.

Severe traumatic brain injury in Switzerland - feasibility and first results of a cohort study.

BACKGROUND: We aimed to study the incidence and outcome of severe traumatic brain injury (TBI) in Switzerland and to test the feasibility of a large cohort study with case identification in the first 24 hours and 6-month follow-up. METHODS: From January to June 2005, we consecutively enrolled and followed up all persons with severe TBI (Abbreviated Injury Score of the head region >3 and Glasgow Coma Scale <9) in the catchment areas of 3 Swiss medical centres with neurosurgical facilities. The primary outcome was the Extended Glasgow Outcome Scale (GOSE) after 6 months. Secondary outcomes included survival, Functional Independence Mea - sure (FIM), and health-related quality of life (SF-12) at defined time-points up to 6 months after injury. RESULTS: We recruited 101 participants from a source population of about 2.47 million (ie, about 33% of Swiss population). The incidence of severe TBI was 8.2 per 100,000 person-years. The overall case fatality was 70%: 41 of 101 persons (41%) died at the scene of the accident. 23 of 60 hospitalised participants (38%) died within 48 hours, and 31 (53%) within 6 months. In all hospitalised patients, the median GOSE was 1 (range 1-8) after 6 months, and was 6 (2-8) in 6-month survivors. The median total FIM score was 125 (range 18-126); median-SF-12 component mea - sures were 44 (25-55) for the physical scale and 52 (32-65) for the mental scale. CONCLUSIONS: Severe TBI was associated with high case fatality and considerable morbidity in survivors. We demonstrated the feasibility of a multicentre cohort study in Switzerland with the aim of identifying modifiable determinants of outcome and improving current trauma care.

Acquired and Congenital Ocular Toxoplasmosis Experimentally Induced in Calomys callosus (Rodentia, Cricetidae)

An experimental model for acquired and congenital ocular toxoplasmosis as well as a model to induce experimental autoimmune uveitis (EAU) was investigated in Calomys callosus. Toxoplasma gondii, ME-49 strain, was used to infect males and pregnant- and not pregnant-females while S-antigen, a major glycoprotein of the retinal photoreceptor cell, was used to induce EAU. The ocular lesions elicited by T. gondii were characterized by the presence of cysts, free tachyzoites and inflammatory cells in the retina or related tissues. In the congenital form, 40% of the fetus presented ocular lesions, i.e., presence of cysts in the retina, vitreous, and extra-retinal tissues. In the acquired form, 75% of the females and 50% of the males presented unilateral ocular cysts both at 21 and 47 days post-infection. It was also demonstrated that S-antigen was not uveitogenic in the C. callosus model. No lesion was observed in the animals exclusively immunized with this retinal component, even when jacalin was used as additional adjuvant for polyclonal response to the retinal antigen. It can be concluded that C. callosus may constitute in a promising model for study both acquired and congenital ocular toxoplasmosis, particularly when it is important to make sure that a non autoimmune process is involved in the genesis of the ocular infection.

Eficacia y Seguridad del tratamiento con Tocilizumab en pacientes con Artritis Reumatoide

L'artritis reumatoide (AR) és una malaltia inflamatòria crònica de caràcter sistèmic que afecta de manera preferent a les articulacions. El tractament de l'AR ha canviat de forma radical en l'última dècada. Això és a causa del desenvolupament de nous tractaments biològics dirigits contra molècules directament implicades en la patogènesi de l'AR. Un d'aquests tractaments és el Tocilizumab (RoACTEMRA ®) un anticòs monoclonal humanitzat que bloqueja l'acció de la Interleucina-6. TCZ ha estat aprovat recentment per al tractament de l'AR. El present projecte té com a objectiu avaluar la seguretat i eficàcia de TCZ en pacients amb AR inclosos en l'assaig clínic ACT-SURE (MA21573), provinents de la consulta externa monogràfica de pacients amb AR de l'Hospital Universitari Vall d'Hebron.

Els cócs : Una senya d'identitat a la Terra Alta

He organitzat aquest escrit de la manera següent: començo amb una visió general de l'entorn social i econòmic de la comarca, faig esment de breus aspectes lingüístics dels mots, continuo amb un breu repàs de la literatura culinària, principalment a Catalunya, i amb una breu visió històrica, continuo amb el món del pa i de la pastisseria i acabo amb la visió més lúdica dels cócs: el moment de consumir-los. Finalment entro en l'exposició de les receptes més genuïnes dels cócs terraltins, mirant que quedi tot ben clar, gràcies a la informació desinteressada de les persones a qui he consultat, i les comparo amb altres de semblants que trobem en antics manuscrits medievals. Per acabar, mostro quines conclusions podem extreure sobre els cócs i els dolços de la Terra Alta, vinculades bàsicament amb el seu origen i la seva continuïtat fins als nostres dies.

Analyse de la prise en charge médicale et de l'impact économique des patients ayant présentés des coûts extrêmes dans un hôpital universitaire [Analysis of the medical management and the economic impact of patients who have represented extreme costs at a university hospital]

Les coûts de traitement de certains patients s'avèrent extrêmement élevés, et peuvent faire soupçonner une prise en charge médicale inadéquate. Comme I'évolution du remboursement des prestations hospitalières passe à des forfaits par pathologie, il est essentiel de vérifier ce point, d'essayer de déterminer si ce type de patients peut être identifié à leur admission, et de s'assurer que leur devenir soit acceptable. Pour les années 1995 et 1997. les coûts de traitement dépassant de 6 déviations standard le coût moyen de la catégorie diagnostique APDRG ont été identifiés, et les dossiers des 50 patients dont les coûts variables étaient les plus élevés ont été analysés. Le nombre total de patients dont I'hospitalisation a entraîné des coûts extrêmes a passé de 391 en 1995 à 328 patients en 1997 (-16%). En ce qui concerne les 50 patients ayant entraîné les prises en charge les plus chères de manière absolue, les longs séjours dans de multiples services sont fréquents, mais 90% des patients sont sortis de l'hôpital en vie, et près de la moitié directement à domicile. Ils présentaient une variabilité importante de diagnostics et d'interventions, mais pas d'évidence de prise en charge inadéquate. En conclusion, les patients qualifiés de cas extrêmes sur un plan économique, ne le sont pas sur un plan strictement médical, et leur devenir est bon. Face à la pression qu'exercera le passage à un mode de financement par pathologie, les hôpitaux doivent mettre au point un système de revue interne de I'adéquation des prestations fournies basées sur des caractéristiques cliniques, s'ils veulent garantir des soins de qualité. et identifier les éventuelles prestations sous-optimales qu'ils pourraient être amenés à délivrer. [Auteurs] Treatment costs for some patients are extremely high and might let think that medical care could have been inadequate. As hospital financing systems move towards reimbursement by diagnostic groups, it is essential to assess whether inadequate care is provided, to try to identify these patients upon admission, and make sure that their outcome is good. For the years 1995 and 1997, treatment costs exceeding by 6 standard deviations the average cost of their APDRG category were identified, and the charts of the 50 patients with the highest variable costs were analyzed. The total number of patients with such extreme costs diminished from 391 in 1995 to 328 in 1997 (-16%). For the 50 most expensive patients, long stays in several services were frequent, but 90% of these patients left the hospital alive, and about half directly to their home. They presented an important variation in diagnoses and operations, but no evidence for inadequate care. Thus, patients qualified as extreme from an economic perspective cannot be qualified as such from a medical perspective, and their outcome is good. To face the pressure linked with the change in financing system, hospitals must develop an internal review system for assessing the adequacy of care, based on clinical characteristics, if they want to guarantee good quality of care and identify potentially inadequate practice.

PHA advises 'breast is best'!

The Public Health Agency is using National Breastfeeding Awareness Week (NBAW) to emphasise the message that breastfeeding is the healthiest option for both you and your baby and that by deciding to breastfeed, you will be giving your child the best possible start in life. NBAW runs from 19-25 June and highlights the fact that any period of breastfeeding, however short, will benefit your baby.Breast milk is different to formula milk as it contains antibodies that cannot be manufactured in formula. Antibodies help protect babies from infection and stimulate their immune system.Northern Ireland has the lowest breastfeeding rate in the UK, with an average of 63% of women breastfeeding their baby at birth. Janet Calvert, Regional Breastfeeding Coordinator at the PHA, said: "This is an issue that clearly needs addressed, as breastfeeding has many important health benefits for both mother and baby. These include a reduced risk of ear, chest, kidney and stomach infections and less risk of childhood diabetes and obesity."Breastfeeding can also significantly reduce the risk of hospital admission of children for gastroenteritis and chest infections. The health benefits for mothers who choose to breastfeed include a reduced risk of developing illnesses such as breast cancer, ovarian cancer and osteoporosis."There are other benefits as well as those to your health. Breastfeeding is free - you don't have to buy formula, bottles, teats, sterilising equipment etc. Breast milk is always available, with the right ingredients, at the right temperature, so it's easier to feed at night or on the go.The PHA recognises the importance of breastfeeding to health and the need to ensure that mothers get off to a good start with breastfeeding. It is vital that mothers get the right support and encouragement from their family and friends should they decide to breastfeed. Breastfeeding can be difficult at the start and mothers need reassurance while they learn."There are many local initiatives in the community to improve breastfeeding support. These include improving support in the health service and through Sure Start programmes, which work in areas of need to help ensure children get the best start in life," Janet added."Mother to mother peer support programmes are in place in many areas and are working with expectant and new mothers to help them breastfeed for longer. There are also 70 breastfeeding support groups, which provide ongoing support for breastfeeding mothers throughout Northern Ireland. "The PHA is also working to improve attitudes to breastfeeding in public through the Breastfeeding Welcome Here scheme, which began in 2005 and now has over 200 businesses and public facilities signed up to support and welcome breastfeeding families. All these initiatives, along with support from partners and family, are vital to help expectant and new mothers stay with breastfeeding."Health Minister Edwin Poots said: "There is clear evidence that breastfeeding offers health benefits for both babies and mothers. We know that breast milk gives baby the best start in life by providing all the nutrients and protection a baby needs for the first six months of life. That is why my Department is committed to promoting and supporting breastfeeding".For further information on breastfeeding visit www.breastfedbabies.org.uk

PHA urges parents to get 'at risk' children vaccinated against seasonal flu

The Public Health Agency is urging Northern Ireland parents to make sure children in 'at risk' groups get their flu vaccine early.The message has been issued to parents and carers of children as the PHA's seasonal flu vaccination programme gets underway for 2011/12.It is very important that children with any condition that puts them more at risk of the complications of flu get the vaccine.These 'at risk' conditions include:chronic lung conditions such as asthma;chest infections that have required hospital admission;chronic heart conditions;chronic liver disease;chronic kidney disease;diabetes;lowered immunity due to disease or treatment such as steroids or cancer therapy;chronic neurological conditions such as stroke, multiple sclerosis or a condition that affects the nervous system, such as cerebral palsy;hereditary and degenerative diseases of the central nervous system or muscles.Children who attend special schools for severe learning or physical disabilities are considered to be particularly at risk, as well as those with other complex health needs.The PHA has written to principals of local special schools, as well as parents of children at these schools, to raise awareness of the importance of getting vaccinated early.Dr Richard Smithson, PHA Flu Vaccination Lead, said: "For many people, flu is a short, unpleasant illness, but it does not usually cause any serious problems. However, for others, it can have very serious complications including, in rare cases, being fatal."We have been particularly reminded over the last two winters that children with chronic neurological problems and other complex health needs are very vulnerable to these complications. We have seen children become very seriously ill and, tragically, there have even been a few deaths in children who attend special schools."For this reason, we recommend that all children who attend special schools for severe learning disability, and special schools for physical disability, are offered the flu vaccine early in the autumn, before the flu viruses start circulating."The vaccine is now available from GP surgeries and the PHA recommends that parents check arrangements with their own GP's surgery so that their child can get the jab.The earlier you get vaccinated the better, as it takes the body about 10-14 days after the jab to develop antibodies. These will then protect you against the same or similar viruses if the body is exposed to them. The vaccine contains three strains of the flu virus, which are considered the most likely to be circulating this winter, including the H1N1 (swine flu) virus."Your child needs to get the flu jab every year - the protection it gives only lasts for one winter, so even if they got it last year, they still need to get it this year," added Dr Smithson."Also, if your child has been diagnosed with flu or swine flu in the past couple of years, they will still need the jab this year as there are different types of flu that the jab will protect against. Getting the flu jab is the best way to protect your child against flu and we would strongly recommend that you arrange for them to have it."Although the vaccine gives good protection, no vaccine gives total protection, so if your child develops flu-like symptoms (such as fever, cough, aches and pains, and sore throat) you should contact your GP for advice. If your child has any of these symptoms, they should be kept at home until they feel better."For more information on seasonal flu, go to www.fluawareni.info and follow us on Facebook and Twitter.

Fish pedicures: Information for the Public

Although the risk of catching an infection as a result of a fish spa pedicure is likely to be very low, it cannot be completely excluded. However, there are certain things you can do to further reduce your risk of catching or spreading an infection when having one of these treatments.Choosing a salonUse your personal judgment: as with all beauty salons, if it looks unsanitary, do not go there for your treatment. If you are very concerned about the cleanliness of a salon you visit, you can report this to your local Environmental Health department, who will be able to perform an inspection of the premises.When having a treatment, a trained member of staff should perform an inspection of your feet both beforehand, to check for any broken skin / infections, and afterwards, to check for signs of bleeding. They should also ask you to wash your feet with soap and water before putting them in the tank, to make sure that any products you have used that could be harmful to the fish are washed away, and to reduce the risk of spreading any infection.Ask your therapist what other procedures the salon has in place to minimise the risk of infection. The Health Protection Agency, England has produced a set of guidelines for salons which, if followed, will ensure any potential risk of infection is kept to an absolute minimum.Before having the treatment The HPA has identified a number of health conditions or prior treatments which may mean that you should not have a fish pedicure. These are:Leg waxing or shaving in last 24 hoursAny open cuts/wounds/abrasions/broken skin on the feet or lower legsInfection on the feet (including athlete's foot, verruca)Psoriasis, eczema or dermatitis affecting the feet or lower legsDiabetes (increased risk of infection)Infection with a blood borne virus such as Hepatitis B or Hepatitis C or HIVAny immune deficiency due to illness or medicationBleeding disorders or on anticoagulant medication (e.g. heparin or warfarinMore information and advice on fish spa pedicures and the full set of guidance can be found on the Health Protection website www.hpa.org.uk

A Fitter Future for All - Framework launched

Obesity is a modern lifestyle epidemic that is threatening our health and well-being.This was the key message delivered by Health Minister Edwin Poots at the launch of The Framework for Preventing and Addressing Overweight and Obesity in Northern Ireland 2012-2022: 'A Fitter Future for All'.This ten year strategy will seek to improve the health and wellbeing of people throughout their entire life, from newborns to seniors.Minister Poots said: "We need to face the issue of obesity head on. It's an issue that will require commitment and action from across all sectors, including other government departments and agencies. It is therefore my intention to invest more than £7 million towards tackling the problem of obesity over the next three years."The negative impact on health caused by obesity cannot be over stated. Being obese increases the risk of developing serious illnesses such as heart disease, stroke, some cancers and type 2 diabetes."It is a significant challenge facing modern society and if we don't tackle it now we are storing up a multitude of problems for ourselves in the future."The Minister continued: "More and more of our children and young people are becoming overweight or obese and are putting themselves at risk of developing a range of health problems in their later years."Evidence shows that it is more likely that an obese child will become an obese adult. This in turn will lead to a greater strain on our health and social care services, with more people requiring treatment for obesity related illnesses and specialist care."The proposed framework looks to address a number of key issues, including:-increasing levels of breastfeeding;increasing knowledge and skills about food and its preparationencouraging participation in physical activity;promoting walking and cycling; making sure how we live and where we live encourages and supports healthy eating and physical activity;encouraging and supporting more community involvement with these issues; and;continuation of reformulation of processed foods.The Minister added: "In Northern Ireland 59% of adults are either overweight (36%) or obese (23%). Another worrying statistic is that 8% of children aged 2-15 years were assessed as being obese. These figures demonstrate the scale of the problem and the enormous challenge we are facing."The new framework sets challenging targets. To date we have focussed on simply trying to stop the rise in the levels of obesity, however under A Fitter Future For All we are seeking to actually reduce the level of obesity by 4% and overweight and obesity by 3% among adults. In addition, we are seeking a 3% reduction of obesity and 2% reduction of overweight and obesity among our children and young people." "Meeting these targets will require changes in our lifestyles and behaviours. Most importantly, individuals need to be given the opportunity to make decisions that will benefit their own health and wellbeing".Referring to the 'Give It A Go!' initiative, to increase awareness of the range of nutritional and physical activity initiatives in the southern area, the Minister said: "The Give It A Go! Initiative is a great example of how collaborative work can make such a positive contribution to peoples' lives by providing opportunities for learning, participation in physical activity and for social interaction."Tackling obesity and seeing positive results throughout the life course of the entire population will take time but I strongly believe that the actions set out in this framework will inspire and enable people to improve their diets and be more active."Encouraging people to consider the framework and adopt a healthier lifestyle, the Minister concluded: "Government cannot tackle obesity on its own. We can encourage and promote healthy eating and physical activity but as a society, we must take more individual responsibility for our own health outcomes."Dr Tracy Owen, Consultant in Public Health Medicine with the PHA, said: "The PHA is already working with partner organisations across many of the areas included in the framework 'A Fitter Future for All' and is addressing issues such as developing people's skills and knowledge about healthier eating along with encouraging participation in physical activity. The framework gives us the opportunity to raise awareness of this important area and strengthen action."As the Minister has mentioned, a good example of this coordinated action is the PHA supported initiative Give it a Go! which is providing people in the Southern area with the opportunity to learn about food through supermarket tours and Cook it! classes and to get active through walks, spinning classes and many other activities, all of which are free. These taster sessions are aimed at raising awareness of healthier lifestyles which will ultimately make changes in behaviour more likely."These changes, no matter how small, can help people to lose weight, maintain a healthy weight and bring big benefits to their general health. Importantly, we have developed this joint programme by working closely with our partners, particularly local councils."

Healthy breaks: tasty tips for the under fives

Today the Public Health Agency is launching a new resource pack designed to assist nursery schools and playgroups deliver a healthy breaks scheme.All nursery schools and playgroups in Northern Ireland will receive the pack - 'Healthy breaks for pre-school children' - which includes a poster and information leaflets for parents explaining why a healthy break is so important for pre-school children and some tips and ideas for healthy nutritious breaks.Judith Hanvey, Regional Food in Schools Co-ordinator, appointed jointly by the PHA and the Department of Education, said: "Break-time snacking schemes currently operate in many pre-school settings across Northern Ireland, however they are implemented in different ways. The PHA has developed this new guidance so that any existing or future schemes have the information that they need to deliver a healthy break programme."Judith explained why a healthy break is so important for pre-school pupils."Young children have small stomachs but high requirements for energy (calories) and nutrients. This means that healthy snacks between meals are very important to make sure that they get all the nourishment they need."Childhood is also an important time to establish good eating and drinking habits for later life."Healthy eating schemes give children the knowledge and opportunity to make healthier choices."The Department of Education and Department of Health, Social Services and Public Safety recently launched 'Healthy Food for Healthy Outcomes: Food in Schools Policy', which builds on the nutritional standards which were introduced in 2007 by the Department of Education.The policy encourages a 'whole school approach' to all food and drink provided and consumed in schools. This ensures that children have the opportunity to benefit from a healthy balanced diet, which can aid learning, leading to improved educational outcomes. It also requires that every school should have their own whole-school food policy in place by September 2014. Nursery schools that receive funding from the Department of Education must follow this policy.This is also in line with the position taken by the Department of Health, Social Services and Public Safety's 10 year obesity prevention strategy, A Fitter Future for All, which aims to take a consistent approach to healthy food within early years settings.
