In recent years, IT project failures have received a great deal of attention in the press as well as the boardroom. In an attempt to avoid disasters going forward, many organizations are now learning from the past by conducting retrospectives—that is, project postmortems or post-implementation reviews. While each individual retrospective tells a unique story and contributes to organizational le...

The Math Educational Resources (MER) wiki is an open online learning resource hosted at The University of British Columbia (UBC), aimed at providing math education resources for students and instructors at UBC. In this paper, we will discuss the motivation for creating this resource on the MediaWiki platform, key features of our implementation that support student learning (including the evolut...

| This paper investigates the relevance of the immune system metaphor to Time Dependent Optimization (TDO). At rst, we review previous results underlining the over-average reactiveness and robustness featured by a Simple Artiicial Immnune System (Sais) in comparison to well known evolutionist approaches ((GC99]). Then, we evaluate its immunization capability (i.e. improving robustness to previo...

Market-driven organizations need to structure, store and prioritize their requirements since they often implement the product in successive releases. Through interviews we have seen that the storage can be implemented as a database or a simple Excel sheet open for new requirements to be entered [1]. However, the prioritization is still difficult to manage in practice. In particular, immature or...

This paper discusses how software projects following different processes, which display disparate characteristics, have been categorized and analyzed using statistical techniques to measure and improve process capability. The analysis shows that language type, size of the application and complexity (represented by ratio of Total Project Effort to Build Phase Effort) are the predominant discrimi...

DESIGN Secondary analysis of baseline data from a social marketing intervention designed to change household dietary practices among parents of 3- to 7-year-ol...

Despite the high prevalence of adolescent food insecurity in Ethiopia, there is no study which documented its association with suboptimal dietary practices. The objective of this study is to determine the association between adolescent food insecurity and dietary practices. We used data on 2084 adolescents in the age group of 13-17 years involved in the first round survey of the five year longi...
