The error-related negativity (ERN) is a negative deflection in the event-related potential that occurs approximately 50 ms following the commission of an error at fronto-central electrode sites. Previous models suggest dopamine plays a role in the generation of the ERN. We recorded event-related potentials (ERPs) while 279 children aged 5-7 years completed(More)

The hypothalamic-pituitary-adrenal (HPA) axis underlies both adaptive and maladaptive responses to stress and may be an important marker of childhood vulnerability to psychopathology, although little is known about genetic variants that influence cortisol reactivity. We therefore examined associations between corticotrophin-releasing hormone (CRH) system(More)
Current Web services approaches have many limitations, especially with description, discovery and integration mechanisms. In this paper we present a novel software architecture called aspect-oriented Web services (AOWS) which addresses these problems. AOWS uses descriptions of cross-cutting concerns between Web services to give more complete descriptions of(More)
Current approaches to engineering web service-based software systems are limited by lack of comprehensive web service component characterisations. In this paper, we describe our recent work applying Aspect-Oriented Component Engineering (AOCE) to develop more adaptable, higher quality and more reusable software components for web services. We give examples(More)
Web services have become a popular new technology for describing, locating and using distributed system functionality. However, existing web service development approaches lack aspect-based development support for distributed components. We describe the application of Aspect-Oriented Component Engineering to web service development. This includes grouping(More)
Distributed denial-of-service (DDoS) attacks are increasingly mounted by cyber-criminal gangs to extort money from online businesses. This kind of attacks is normally targeted at a particular service provider to exhaust the network and system resources of the provider. Since the scale of the attack is limited, the ISP operators normally cannot observe this(More)
Aspect-oriented Component Engineering uses early aspects to better categorize and reason about provided and required services of individual components in software systems. Our earlier work on AOCE demonstrated an increase in the reusability and understandability of software components and systems via its usage of early requirements and design-phase aspects(More)
A crash can be thought of as a system composed of several elements, including drivers and vehicles that continually interact with each other, while a crash database is a record of the errors attributable to different components of the crash system. Learning from mistakes (errors) is important if crashes are to be avoided. With more than one hundred(More)
Visibility is one of the basic requirements for safe driving; any type of obscurity in a driver's vision can interfere with the driving task and impose a threat to the roadway safety. Glare is known to be one of the significant factors causing vision obstruction. One would agree that headlamps are not the only source of glare. Sometimes, sunlight may also(More)
