Organizations enter alliances with each other to access critical resources, but they rely on information from the network of prior alliances to determine with whom to cooperate. These new alliances modify the existing network, prompting an endogenous dynamic between organizational action

The World Wide Web is revolutionizing the way that researchers access scientific information. Articles are increasingly being made available on the homepages of authors or institutions, at journal Web sites, or in online archives. However, scientific information on the Web is largely disorganized

Full list of author information is available at the end of the articleAutism spectrum disorders (ASD) represent a group of behaviourally defined neurodevelopmental disorders asso-ciated with disruptions of social, cognitive and/or motor behaviours. Increased understanding and acceptance of ASD in recent clinical practice indicates that the preva-lence of ASD has reached a median rate of 13/10,000 in male/female ratio of 4.4:1 [1]. However, although it is sug-gested that the complex impairments observed in ASD patients are caused by a number of genetic and environ-mental factors, as well as immunological and metabolic status, the neurological aetiology of ASD remains unclear [2-9]. Previous neuroimaging studies have revealed several conserved anatomical alterations in autistic patients that may be relevant to their behavioural abnormalities [10]. These include increased total brain volume, decreased grey matter volume in the amygdala-hippocampal complex,
