In the recent past, a lot of work has been done in establishing public key infrastructures (PKIs) for electronic commerce (e-commerce) applications. Unfortunately, most of these PKIs can only be used to authenticate the participants of e-commerce applications; they can't be used to properly authorize the participants and to control access to system resources accordingly. Consequently, these PKI...

To satisfy service customers and create unique value in a digitized world, companies must strive for exceeding customers’ expectations of e-service experience by establishing high e-service quality. However, an increasing amount of e-services is performed by context-aware mobile technology, which is able to sense and react to changes in the user’s environment. Although these context-aware servi...

Understanding the transcriptional regulationnetworks that control the gene expression programs in a living cell is one of fundamental questions in molecular biology. Using single perturbations allows us to identify the key players in those networks. To better understand the structure, we can use double perturbations to measure genetic interactions between the components in the network. By syste...

With the advent of self-organizing systems such as ad hoc networks or ubiquitous computing, security protocols have to meet a new requirement for establishing trust among parties that have no a priori relationship like a shared naming structure or a common organization. Trust establishment in this context calls for a brand new paradigm with respect to classical scenarios whereby entities build ...

The success of an agent mediated e-market system lies in the underlying reputation management system to improve the quality of services in an information asymmetric e-market. Reputation provides an operatable metric for establishing trustworthiness between mutually unknown online entities. Reputation systems encourage honest behaviour and discourage malicious behaviour of participating agents i...

Arylalkylamine N-acetyltransferase (Aanat) is the penultimate enzyme in the serotonin-N-acetylserotonin-melatonin pathway. It is nearly exclusively expressed in the pineal gland and the retina. A marked rhythm of Aanat gene expression in the rat pineal is mediated by cyclic AMP response elements located in the promoter and first intron. Intron 1 also contains E-box elements, which mediate circa...

Draft genome sequences for Schistosoma japonicum and Schistosoma mansoni are now available. The schistosome genome encodes approximately 13,000 protein encoding genes for which the function of only a small minority is understood. The new genes represent potential intervention targets. Molecular tools are needed to determine the importance of these new genes. There is a role for transgenesis in ...

Objective: To describe the process of establishing and implementing a social support infant feeding intervention. Design: This paper outlines the initial stages of a randomised controlled trial which assessed the effectiveness of a social support intervention on a range of infant feeding outcomes. Details are presented of the processes involved in recruiting, training and supporting a group of ...
