In this paper, we employ the decomposition of a directed network as an undirected graph plus its associated node meta-data to characterise cyclic structure found in networks by finding Minimal Cycle Basis and augmenting components with direction information. We show that only four classes cycles exist, they can be fully distinguished organisation number source–sink pairs their antichain structu...

Proxy-based transcoding adapts Web content to be a better match for client capabilities (such as screen size and color depth) and last-hop bandwidths. Traditional transcoding breaks the end-to-end model of the Web, because the proxy does not know the semantics of the content. Server-directed transcoding preserves end-to-end semantics while supporting aggressive content transformations. We show ...

Games such as the Nintendo WiiTM are being promoted for use by all ages but there is little experience with how groups of older people integrate Wii playing into their physical and social spaces. This paper focuses on WiiTM game play by older people in Sheltered Housing schemes, as part of an initiative to promote physical and social activity in these settings. Using participant observations, i...

To find interesting, personally relevant web content, we often rely on friends and colleagues to pass links along as they encounter them. In this paper, we study and augment link-sharing via e-mail, the most popular means of sharing web content today. Armed with survey data indicating that active sharers of novel web content are often those that actively seek it out, we present FeedMe, a plug-i...

In this demo, we present the VideoLecturesMashup, which delivers re-mixes of learning materials from the VideoLectures.NET portal based on shared topics across different lectures. Learners need more efficient access to teaching on specific topics which could be part of a larger lecture (focused on a different topic) and occur across lectures from different collections in distinct domains. Curre...

purpose: the present study aims at comparing the impact of two teaching/learning approaches-self- directed/paced learning and lecture/demonstration-based instruction-on mastering psychomotor skills among nursing students. material & method: thirty nursing students were selected for the study. they filled out questionnaires indicating the demographic factor, and mean exam scores achieved in the ...
