On including quality in applied automatic gait recognition

Many gait recognition approaches use silhouette data. Imperfections in silhouette extraction have a negative effect on the performance of a gait recognition system. In this paper we extend quality metrics for gait recognition and evaluate new ways of using quality to improve a recognition system. We demonstrate use of quality to improve silhouette data and select gait cycles of best quality. The potential of the new approaches has been demonstrated experimentally on a challenging dataset, showing how recognition capability can be dramatically improved. Our practical study also shows that acquiring samples of adequate quality in arbitrary environments is difficult and that including quality analysis can improve performance markedly

Gait Extraction and Description by Evidence-Gathering

Using gait as a biometric is of increasing interest, yet there are few model-based, parametric, approaches to extract and describe moving articulated objects. One new approach can detect moving parametric objects by evidence gathering, hence accruing known performance advantages in terms of performance and occlusion. Here we show how that the new technique can be extended not only to extract a moving person, but also to extract and concurrently provide a gait signature for use as a biometric. We show the natural relationship between the bases of these approaches, and the results they can provide. As such, these techniques allow for gait extraction and description for recognition purposes, and with known performance advantages of a well-established vision technique

The DAEDALUS project, developing institutional repositories at Glasgow University:the story so far

The DAEDALUS project is funded under the Joint Information Systems Committee, Focus on Access to Institutional Resources Programme for three years until June 2005. The project is based at the University of Glasgow and is developing online institutional repositories for the university, while at the same time encouraging debate and discussion about scholarly communications issues and is made up of two complementary strands: advocacy and service development. This paper sets out the achievements of the project to date and details some of the advocacy strategies that have been used to engage academic staff and researchers with the aims and objectives of the project. Also discussed are some of the barriers which have been faced in obtaining content for the repositories

Hai Karate and Kung Fuey: Early Martial Arts Tropes in British Advertising

This paper focuses on the responsibility of advertising messages to authentically mirror and reflect British audience feelings towards ‘the Other’ and discusses caricatures of the Chinese in advertising through early martial arts tropes. It provides contextual background to Chinese depictions on screen in Britain before illustrating martial arts representations on print and television advertising during the 1970s. The paper includes examples of two popular brands in Britain: Pfizer’s ‘Hai Karate’ (1973) and Golden Wonder’s ‘Kung Fuey’ (1974-76) to illustrate colonial notions of the ‘Oriental’ during the 1960s and ’70s. This interdisciplinary study borrows from ethical representation and martial arts discourse in film and TV, to explain the exoticisation and exclusion of the Chinese in the context of authenticity and appropriation in advertising

Patron-Driven Acquisition: An Introduction and Literature Review

Introductory article to the Special Issue: Patron-Driven Acquisition: Current Successes and Future Direction

Academic E-Books: Publishers, Librarians, and Users

Academic E-Books: Publishers, Librarians, and Users provides readers with a view of the changing and emerging roles of electronic books in higher education. The three main sections contain contributions by experts in the publisher/vendor arena, as well as by librarians who report on both the challenges of offering and managing e-books and on the issues surrounding patron use of e-books. The case study section offers perspectives from seven different sizes and types of libraries whose librarians describe innovative and thought-provoking projects involving e-books. Read about perspectives on e-books from organizations as diverse as a commercial publisher and an association press. Learn about the viewpoint of a jobber. Find out about the e-book challenges facing librarians, such as the quest to control costs in the patron-driven acquisitions (PDA) model, how to solve the dilemma of resource sharing with e-books, and how to manage PDA in the consortial environment. See what patron use of e-books reveals about reading habits and disciplinary differences. Finally, in the case study section, discover how to promote scholarly e-books, how to manage an e-reader checkout program, and how one library replaced most of its print collection with e-books. These and other examples illustrate how innovative librarians use e-books to enhance users’ experiences with scholarly works.https://docs.lib.purdue.edu/purduepress_ebooks/1036/thumbnail.jp

Introduction to Academic E-Books

With so many advantages, it seems logical that librarians would be eager to switch from purchasing books in print to embrace the electronic format. However the transition to e-books in academic libraries has not been a smooth or quick one and the reasons are myriad and complicated. Aware that this is still a time of transition and that there are many issues surrounding the e-book, the editors set out to present the state of e-books in academic libraries today. They invited knowledgeable publishers and librarians to write about the current challenges, successes, and trends. In addition, there is a section that analyzes new data about user interaction with e-books and an essay written by a teaching faculty member who uses and encourages her student to use e-book

Pressure ulcer related pain in community populations: a prevalence survey.

BACKGROUND: Pressure ulcers are costly to the healthcare provider and can have a major impact on patient's quality of life. One of the most distressing symptoms reported is pain. There is very little published data on the prevalence and details of pain experienced by patients with pressure ulcers, particularly in community populations. The study was conducted in two community NHS sites in the North of England. METHODS: The aim was to estimate the prevalence of pressure area related pain within a community population. We also explored the type and severity of the pain and its association with pressure ulcer classification. A cross-sectional survey was performed of community nurses caseloads to identify adult patients with pressure ulcers and associated pain. Consenting patients then had a full pain assessment and verification of pressure ulcer grade. RESULTS: A total of 287 patients were identified with pressure ulcers (0.51 per 1000 adult population). Of the 176 patients who were asked, 133 (75.6%) reported pain. 37 patients consented to a detailed pain assessment. Painful pressure ulcers of all grades and on nearly all body sites were identified. Pain intensity was not related to number or severity of pressure ulcer. Both inflammatory and neuropathic pain were reported at all body sites however the proportion of neuropathic pain was greater in pressure ulcers on lower limbs. CONCLUSIONS: This study has identified the extent and type of pain suffered by community patients with pressure ulcers and indicates the need for systematic and regular pain assessment and treatment
