Hadoop MapReduce is a powerful open-source framework towards big data processing. For ordinary users, it is not hard to write MapReduce programs but hard to specify memory-related configurations. To help users analyze, predict and optimize job’s memory consumption, this technical report presents a fine-grained memory usage model. The proposed model reveals the relationship among memory usage, d...

Since the last major empirical review on choice interventions and preference assessments among people with severe to profound developmental disabilities (Lancioni, O'Reilly, & Emerson, 1996) the body of research in this area has grown extensively. This paper reviews thirty studies carried out between 1996 and 2002 that have been sorted into four categories. These categories are (a) building cho...

We are presenting a tool for collecting and analysing computer usage data. The observed data are locally used by the user to self-monitor and self-reflect her behaviour, decontrolling the data for personalisation of information environments only with her consent. 1

A core goal of librarians is to maximize usage of the content to which their libraries subscribe. Webscale or resource discovery systems offer a single search box for library users to access subscribed content. This article examines usage data at the University of Huddersfield to show how resource discovery has helped to increase the usage of publisher content, which has been made available to ...

We report the case of a young man who accidentally received a prolonged electric discharge from electrical wires and released the electric source with the help of an inappropriate shock from his implantable cardioverter-defibrillator (ICD), after misinterpretation of the electrical signal by the device as a ventricular tachycardia. This case illustrates the "electrical noise" phenomenon, and un...

[email protected] Editor – We read with interest the study by Chan et al into the effect of needling HT7 on psychological stress in hospice staff. We agree that stress in hospice staff is an important problem and that a simple effective treatment would be useful. However, although Chan et al aimed to measure reductions in psychological stress, we feel that the outcome measure they chose wa...

MIS researchers have developed a number of models for studying the software utilization choices of end users. In this paper, we focus on one of these, the Task-Technology fit model. We explore the addition of various personal characteristic constructs, especially Computer Self-Efficacy and Experience.

In this paper, we present selected findings from our usage analysis of an online English Language Teaching (ELT) workbook. We focus on how teachers assign activities and how learners complete them.
