Can human social cognitive processes and social motives be grasped by the methods of experimental economics? Experimental studies of strategic cognition and social preferences contribute to our understanding of the social aspects of economic decisions making. Yet, papers in this issue argue that the social aspects of decision-making introduce several difficulties for interpreting the results of economic experiments. In particular, the laboratory is itself a social context, and in many respects a rather distinctive one, which raises questions of external validity.

IQ in children with autism spectrum disorders: data from the Special Needs and Autism Project (SNAP)
Resumo:
Background Autism spectrum disorder (ASD) was once considered to be highly associated with intellectual disability and to show a characteristic IQ profile, with strengths in performance over verbal abilities and a distinctive pattern of ‘peaks’ and ‘troughs’ at the subtest level. However, there are few data from epidemiological studies. Method Comprehensive clinical assessments were conducted with 156 children aged 10–14 years [mean (s.d.)=11.7 (0.9)], seen as part of an epidemiological study (81 childhood autism, 75 other ASD). A sample weighting procedure enabled us to estimate characteristics of the total ASD population. Results Of the 75 children with ASD, 55% had an intellectual disability (IQ<70) but only 16% had moderate to severe intellectual disability (IQ<50); 28% had average intelligence (115>IQ>85) but only 3% were of above average intelligence (IQ>115). There was some evidence for a clinically significant Performance/Verbal IQ (PIQ/VIQ) discrepancy but discrepant verbal versus performance skills were not associated with a particular pattern of symptoms, as has been reported previously. There was mixed evidence of a characteristic subtest profile: whereas some previously reported patterns were supported (e.g. poor Comprehension), others were not (e.g. no ‘peak’ in Block Design). Adaptive skills were significantly lower than IQ and were associated with severity of early social impairment and also IQ. Conclusions In this epidemiological sample, ASD was less strongly associated with intellectual disability than traditionally held and there was only limited evidence of a distinctive IQ profile. Adaptive outcome was significantly impaired even for those children of average intelligence.

A robot mounted camera is useful in many machine vision tasks as it allows control over view direction and position. In this paper we report a technique for calibrating both the robot and the camera using only a single corresponding point. All existing head-eye calibration systems we have encountered rely on using pre-calibrated robots, pre- calibrated cameras, special calibration objects or combinations of these. Our method avoids using large scale non-linear optimizations by recovering the parameters in small dependent groups. This is done by performing a series of planned, but initially uncalibrated robot movements. Many of the kinematic parameters are obtained using only camera views in which the calibration feature is at, or near the image center, thus avoiding errors which could be introduced by lens distortion. The calibration is shown to be both stable and accurate. The robotic system we use consists of camera with pan-tilt capability mounted on a Cartesian robot, providing a total of 5 degrees of freedom.

This paper presents a preface to this Special Issue on the results of the QUEST-GSI (Global Scale Impacts) project on climate change impacts on catchment-scale water resources. A detailed description of the unified methodology, subsequently used in all studies in this issue, is provided. The project method involved running simulations of catchment-scale hydrology using a unified set of past and future climate scenarios, to enable a consistent analysis of the climate impacts around the globe. These scenarios include "policy-relevant" prescribed warming scenarios. This is followed by a synthesis of the key findings. Overall, the studies indicate that in most basins the models project substantial changes to river flow, beyond that observed in the historical record, but that in many cases there is considerable uncertainty in the magnitude and sign of the projected changes. The implications of this for adaptation activities are discussed.

At the heart of the ‘special relationship’ ideology, there is supposed to be a grand bargain. In exchange for paying the ‘blood price’ as America's ally, Britain will be rewarded with exceptional influence over American foreign policy and its strategic behaviour. Soldiers and statesman continue to articulate this idea. Since 9/11, the notion of Britain playing ‘Greece’ to America's ‘Rome’ gained new life thanks to Anglophiles on both sides of the Atlantic. One potent version of this ideology was that the more seasoned British would teach Americans how to fight ‘small wars’ in Iraq and Afghanistan, thereby bolstering their role as tutor to the superpower. Britain does derive benefits from the Anglo-American alliance and has made momentous contributions to the wars in Afghanistan and Iraq. Yet British solidarity and sacrifices have not purchased special influence in Washington. This is partly due to Atlanticist ideology, which sets Britain unrealistic standards by which it is judged, and partly because the notion of ‘special influence’ is misleading as it loses sight of the complexities of American policy-making. The overall result of expeditionary wars has been to strain British credibility in American eyes and to display its lack of consistent influence both over high policy and the design and execution of US military campaigns. While there may be good arguments in favour of the UK continuing its efforts in Afghanistan, the notion that the war fortifies Britain's vicarious world status is a dangerous illusion that leads to repeated overstretch and disappointment. Now that Britain is in the foothills of a strategic defence review, it is important that the British abandon this false consciousness.
