Research Aims E-learning Environments and Services (ELES) adoption and success rates continue to pose a challenge for ELES designers, practitioners and organisations. The enterprise decision makers continue to seek effective instruments in launching such systems. This study aims at understanding users’ perceptions of ELES and at developing a theoretical framework to improve understanding of suc...

Many cultures have reported end-of-life experiences (ELEs) as part of the dying process. However, few studies have examined the mental states of the dying in the weeks and days before death. Following an ELE pilot study with a palliative care team, 38 nurses, doctors and end-of-life carers from two hospices and a nursing home took part in a 5-year retrospective followed by a 1-year prospective ...

This paper focuses on the use of distributed memory multithreaded environments in data parallel programs and has two main goals. The rst is to show that data parallel programs can support features like communication overlapping, load balancing without global data parallel object redistribution and the eecient use of clusters of uniprocessor and/or symmetric multiprocessors (SMPs). Our extended ...

It is well-known that most scheduling problems arising from parallel systems are NP-hard, even under very special assumptions. Thus various suboptimal algorithms, in particular heuristics, were proposed in the literature. Worst-case error bounds are established in this note for heuristics of makespan minimization of parallel computations. Diierent parallel computation models are investigated, i...

Degradable performance of fault-tolerant computer systems has given rise to considerable interest in mathematical models for combined evaluation of performance and reliability. Most of these models are based upon Markov processes. Several methods have been proposed for the computation of the probability distribution of performability upon an interval of time 0; t]. In this paper, two closed for...

Research on the link between recall of early parenting and psychopathology has focused on recall of parental behaviours such as neglect, rejection, low warmth and overprotection. This study investigates recall of the personal feelings of perceived threat and subordination in childhood. A short, new self-report scale was developed, called the Early Life Experiences Scale (ELES) and given to 225 ...
