The Department of Information Science is one of six departments that make up the Division of Commerce at the University of Otago. The department offers courses of study leading to a major in Information Science within the BCom, BA and BSc degrees. In addition to undergraduate teaching, the department is also strongly involved in postgraduate research programmes leading to MCom, MA, MSc and PhD ...

With the publication of the article by Benoit Roux and colleagues in this issue (Vargas et al.), the JGP introduces a new type of article, the Viewpoint. A Viewpoint shares features with two other article types, Perspectives and Reviews, but is distinct from them. Like the Perspective, a Viewpoint will present a summary and critical analysis of a scientific issue of strong current interest to t...

BACKGROUND: Umbilical metastases from a malignant neoplasm, also termed Sister Mary Joseph's nodule, are not commonly reported in the English literature, and they have usually been considered as a sign of a poor prognosis for the patient. The present article reports on the current view point on umbilical metastasis besides discussing the epidemiology, clinical presentation, pathophysiology and ...

In this paper, we discuss QoE (Quality of Experience) requirements for MVV (Multi-View Video) and audio transmission over IP networks and study the effect of the playout buffering time, contents and viewpoint change interfaces on the QoE and user’s behavior. Unlike previous works, which mainly discuss MVV transmission from aspects of video codecs, we study MVV and audio transmission under vario...

This paper proposes a viewpoint invariant face recognition method in which several viewpoint dependent classifiers are combined by a gating network. The gating network is designed as autoencoder with competitive hidden units. The viewpoint dependent representations of faces can be obtained by this autoencoder from many faces with different views. Multinomial logit model is used for the viewpoin...

Viewpoints are re ections of software systems from multiple perspectives. A number of consistency conditions apply to viewpoints and developers require a tool for each type of viewpoint. These tools need to support consistency management. Inter-viewpoint consistency can only be checked when tools are integrated into a viewpoint development environment. We brie y outline the functionality develo...

In two experiments we examined the ability of human observers to recognize faces from novel viewpoints. Previous work has indicated that there are marked declines in recognition performance when observers learn a particular view of a face and are asked to recognize the face from a novel viewpoint. We replicate these ndings and extend them in several ways. First, we replicate the well-known 3/4 ...

In November 2011, I finally gave in to my bowels. Frequency and slime were one thing, but bleeding was the game changer. A delay of 6 months cost me a lymph node, allowing my rectum to enjoy a second course of chemotherapy. The offending mass had already been removed and fried and a year later, cancer over and my white count recovering, I was back at work. Just another patient benefiting from s...
