The aim of this investigation was to examine the influence of pediatric sport-related concussion on brain and cognitive function. To do so, we used a between-participants design, measures of executive control, and event-related potentials (ERPs). The findings demonstrate that children with a history of concussion exhibit behavioral deficits in attention, working memory and impulse control, as w...

This paper uses data on elected village councils in South India to examine the political economy of public resource allocation. We find that the pattern of policy-making reflects politicians’ self-interest. Elected councillors benefit from improved personal access to public resources. In addition, the head councillor’s group identity and residence influences public resource allocation. While el...

This study investigated the mechanism that underlies the inefficient allocation of attentional resources in Attention-Deficit/Hyperactivity Disorder (AD/HD). The P300 event-related brain potential (ERP) was elicited from 24 healthy adults using a visual three-stimulus oddball paradigm (standard, 70%; target, 15%; non-target, 15%) and the degree of their AD/HD symptoms was assessed by using AD/H...

We live within an increasingly technological, information-laden environment for the first time in human evolution. This subjects us (and will continue to subject us in an accelerating fashion) to an unremitting exposure to 'meaningful information that requires action'. Directly dependent upon this new environment are novel evolutionary pressures, which can modify existing resource allocation me...

Costs incurred in the manufacture of ejaculates may constrain the number of sperm that males can produce, so males should show some economy in their allocation of sperm across multiple matings. In species in which females mate with multiple males and are capable of storing sperm for extended periods, sperm allocation of males should be tailored to the risk of sperm competition. Recent game theo...

The effect of the choice of control allocation scheme upon individual control effector rate demands is examined. Three previously reported and one new variation of control allocation schemes are described and compared. The new allocation scheme exploits the maximum attainable moment-rates of a given control effector configuration and is called moment rate allocation. The bases of comparison are...

The last chapter looked at feeding as a typical motivational system and examined the effects of variables such as palatability, diet dilution, and brain damage on the amount eaten and how hard a rat will work for food. These effects were quite well summarized by a simple, static feedback model whose central assumption is that animals regulate 1 eating rate. Chapter 6 did not deal directly with ...

The paper analyses the factors involved in a series of decisions by the Newcastle Area Health Authority concerning the future of one of its hospitals, as an illustration of the way in which choices about priorities in the health service are actually made. There is no easy way to resolve the various conflicts of interest, notably in this case the competing demands of acute and chronic medicine. ...
