title: Incremental mining of frequent serial episodes considering multiple occurrences

authors: Guyet, Thomas

subjects: computer science

abstract: The need to analyze information from streams arises in a variety of applications. One of its fundamental research directions is to mine sequential patterns over data streams. Current studies mine series of items based on the presence of the pattern in transactions but pay no attention to the series of itemsets and their multiple occurrences. The pattern over a window of itemsets stream and their multiple occurrences, however, provides additional capability to recognize the essential characteristics of the patterns and the inter-relationships among them that are unidentifiable by the existing presence-based studies. In this paper, we study such a new sequential pattern mining problem and propose a corresponding sequential miner with novel strategies to prune the search space efficiently. Experiments on both real and synthetic data show the utility of our approach.

title: Positioning Functional Foods for Sports Performance - A Case Study: A food producer's communication with external stakeholder groups

authors: Johnson, Vanessa

subjects: Functional Foods

abstract: Increased consumer and professional interest in healthy foods and beverages, coupled with recent advances in food science technology, have seen food-producing organisations create and market food products claiming to offer physiological benefits beyond their basic nutritional value. These functional foods have sparked considerable public debate despite growing in popularity and availability. To date, empirical research on functional foods has focused mostly on consumer and medical professional perspectives. However, this case study focuses on the perspective of the food-producing organisation. In this case study I examine how one food-producing organisation tries to balance the tensions it faces in developing and producing functional foods. My interest is in how organisational assumptions affect research and development decisions, and subsequent communication with external stakeholders. The functional foods are beverages which can aid sports performance. The external stakeholders are to primarily be sportspeople (meaning highly competitive sportspeople and elite athletes), but I also include other relevant external stakeholder groups such as coaches, and health professionals. The data collection comprises semi-structured one-on-one interviews with organisational members involved in research and development, nutrition claims, marketing, and branding; together, with a review of secondary organisational information taken from websites and advertisements. The interpretive thematic analysis shows that this food-producing organisation made specific organisational assumptions about health, functional foods, sportspeople, and other consumer groups. The findings demonstrate that the organisation juggles multiple identities at a product, brand and organisational level in order to connect with the broadest range of stakeholders possible. This creates tensions concerning where the focus for product development, branding, and other communication should reside, which have financial and legislative consequences; in turn potentially affecting organisational reputation. One implication of this research is that in trying to connect with too broad a range of stakeholders the organisation may start losing the brand credibility it has thus far built up with specific consumer groups, such as sportspeople, and compromise the respect of professional interest groups and expert stakeholders.

title: Rangatiratanga - Kawanatanga: Dealing with rhetoric

authors: Nikora, Linda Waimarie

abstract: Numbered among the few Maori appointed to an academic position during the late 1980s, I have seen our discipline and profession, in all its awkward self-consciousness, make genuine attempts to grapple the respond to questions and challenges delivered by Maori and Pakeha alike.  For example, Where is the Maori content in courses?  Why aren’t Maori graduating from professional training programmes?  Why are there not more Maori academics? Where is the place/space for Maori as practitioners, academics, researchers and decision-makers?  Why does it seem that Maori are always on the ‘client’ side of the professional/client equation?  Where are the Maori men?  In responding to these persistent challenges the professional and discipline in Aotearoa/New Zealand has been irreversibly changed, in my opinion.  The change has not been dramatic (psychology is somewhat averse to self-promotion) but, of those changes that have occurred, a definite contribution has been made to advancing Maori development, to building a more bicultural discipline and practice, and to supporting the strength of the Kawanatanga and Rangatiratanga dynamic whose importance I emphasize here.
