title: Comparison of various methods to delineate blood vessels in retinal images

authors: Cree, Michael J.

subjects: engineering

abstract: The blood vessels in the human retina are easily visualisable via digital fundus photography and provide an excellent window to the health of a patient affected by diseases of blood circulation such as diabetes. Diabetic retinopathy is identifiable through lesions of the vessels such as narrowing of the arteriole walls, beading of venules into sausage like structures and new vessel growth as an attempt to reperfuse ischaemic regions. Automated quantification of these lesions would be beneficial to diabetes research and to clinical practice, particularly for eye-screening programmes for the detection of eye-disease amongst diabetic persons.

title: Number-fact knowledge and mathematical problem-solving of five-to seven-year olds

authors: Young-Loveridge, Jennifer

abstract: This paper examines children's number fact knowledge in relation to mathematics problem solving. These findings are derived from a study that set out to explore the impact on mathematics learning of using multiplication and division contexts with 84 five- to seven-year-old children from diverse cultural and linguistic backgrounds. After a series of focused lessons, children's knowledge of number facts, including single-digit addition, subtraction, and doubles improved substantially. However, children did not always apply this knowledge to relevant problem-solving situations. The difficulty level for recalling number facts was not directly related to the magnitude of the numbers, with certain salient facts such as 5+5 and 10+10 learned earlier than facts with smaller sums such as 2+3 and 1+4.

title: The importance of Māori identity for athletes and sportspeople within sporting contexts

authors: Westrupp, Maia Takamoana

subjects: Māori

abstract: Identity is an important concept within psychology given its influence upon how we perceive ourselves, who we are as people, and how it can impact behaviour. For Māori, colonisation has had a detrimental impact on the maintenance and flourishing of a strong cultural identity. Sport is an area where Māori have not only contributed successfully nationally and internationally alongside Pakeha, but have been able to either affirm or rebuild their sense of cultural identity and connectedness. The purpose of this thesis is to examine the importance of Māori identity for athletes and sports people within a sporting context. This research project encompassed a qualitative approach, drawing upon a kaupapa Māori research paradigm. Semi-structured interviews were employed to ascertain in depth knowledge of participant’s experiences. A total of six participants took part in this study, all of whom were made up of athletes, coaches, and sports psychologists. When interpreting participants understanding of Māori identity within a sporting context, participants indicated a desire to configure their Māori identity based on Māori cultural concepts such as whakapapa, manaakitanga, and pēpeha. The key findings also identified a link between Māori identity and sport as participants illustrated how important Māori identity was within their sports team and organisation. Participants also indicated an unconscious link to enhanced sporting behaviours given the essence of Māori identity and the significance it places on serving the collective. Ultimately, for Māori athletes and sports people, the sporting realm offers an opportunity to engage and reaffirm Māori identity. Additionally, the value sporting teams and organisations place on Māori identity, can lead to flourishing in sport given the behaviours that may transpire by connecting the individual beyond purely, the physical domain.
