We describe a prototype system we have developed that incorporates best practices identified from a 2003 study of both public and private E-tax filing websites hosted in the USA. Our motivation is to investigate the current low functionality and low penetration usage of online tax filing, an increasingly important webapplication. We identify critical security and usability features in current u...

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...

They endure the trauma of street life, often contending with mental health and sub stance use issues. They lack the education and work experience necessary to find employment.

Metaphor recognition presents a computational challenge, in part due to metaphoric deviation from literal thinking, and also because of a metaphor’s various linguistic expressions. This article forwards a new computational method, an integrated treatment of metaphor recognition from the computational perspective, which recent related studies have not entirely addressed. The authors differentiat...

This method provides several simple and effective practices to manage software projects. However, despite of its simple structure, lots of challenges and issues have been reported during Scrum adoption. Te main aim of this paper is to report the main issues of intro...

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...

OBJECTIVE The present study examined whether characteristics such as quality, selection and convenience are associated with dietary intake of fruits and vegetables independent of perceived costs in an inner-city, low-income population. 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...
