title: Suboptimal Choice Behaviour across Different Reinforcement Probabilities

authors: Yang, Le

abstract: Six adult roosters’ choice behaviour was investigated across a series of five experimental conditions and a series of replication of the same five experimental conditions. Stagner and Zentall (2010) found that pigeons prefer to choose an alternative with highly reliable discriminative stimuli but with less food reward over an alternative with non-discriminative stimuli but with more food reward. The current research systematically changed the probability of reinforcement associated with the discriminative stimulus through a series of experimental conditions. Experimental sessions were completed with six adult roosters. The experimental procedure was based on Stagner and Zentall’s (2010) experiment in which the suboptimal alternative with discriminative stimuli was associated with 100% reinforcement on 20% of the trials, and non-reinforcement on 80% of the trials; the optimal alternative with non-discriminative stimuli was associated with both 50% reinforcement on all trials. This research modified the probabilities of reinforcement associated with the discriminative alternative. In the first experimental condition, the probability of getting access to reinforcement was the same (50%) for each discriminative stimulus, thus, what was seen for the first time was that both alternatives were associated with non-discriminative stimuli. To insure reliability, a replication of the conditions was done after the first five experimental conditions were completed. The results showed that four of the roosters had suboptimal choice behaviour in the first five experimental conditions; however, only two of them maintained such suboptimal behaviour in the replication conditions. This result does not support the idea that the suboptimal choice behaviour with strong discriminative stimuli is a robust effect.

title: Place of theory: Locating the New Zealand Education PhD experience

authors: Middleton, Sue

subjects: education

abstract: The year 1998 marked 50 years of doctoral study in New Zealand, and in 1999 I embarked on a history of Ph.D. theses in Education. Influenced by Foucaultian genealogy, this employed a fusion of bibliographic, archival and life-history interview methods. One hundred and eighty-three Education theses were identified and 57 of these graduates interviewed. How has New Zealand's 'corpus' of Education Ph.D. thesis production been enabled and constrained by its temporal/spatial location? To address this, I draw on geographical debates on 'space' and 'place'. The first part contextualises thesis topics, theories and methods in discourses of international scholarship, New Zealand politics and social change. The second part narrates a parallel history of the changing circumstances and sites of thesis production—biographical, domestic and institutional. It integrates students' accounts of thesis work's epistemological, methodological, spatial and technological dimensions to suggest a history of New Zealand doctoral candidates' experience.

title: Sport in the Waikato c.1897-1974: Narratives of Play, Identity and Belonging

authors: Buckley, Karen

subjects: sport

abstract: Regional identities and allegiances in New Zealand have most often been revealed at sporting events. From the colours worn, the slogans chanted, and even the ringing of cowbells, players, teams and supporters have presented facets of their collective character. This thesis engages with narratives of sport in the Waikato region over a period of eighty years to examine these representations as they produced meanings of sporting activities for local people. Informed by competing ideas about historical truth, the thesis interprets printed media as reconstructions of both recurring events, and belonging and membership, to investigate the place of sport in the region, and to decode the ways these stories of drama and contest contribute to the development of some components of a local identity.
Historically, the area now known as the ‘Waikato’ was part of the Auckland Province. The thesis argues that sport is at the centre of a notion of separation from the urban metropolis, and provided opportunities to demonstrate a growing independence. By examining examples of recurring sporting events such as the annual Ngāruawāhia Regatta, regular Auckland/Waikato rugby matches, Empire and Commonwealth Games participation, and regular lawn bowls tournaments, the place and function of sport in a regional space is able to be, in part, exposed. Uneven, often subtle, changes both in aspects of these events and in the representations of them, reveal underlying tensions and power relationships.
Local, if not exclusive, understandings of the place and role of Māori, and depictions of normative gender roles, are central to the analysis of these relationships. Sport is most often a social activity, and dissection of the newspaper texts has enabled the formation of ideas about the ways sports-men, and sometimes women, are collectively presented and organised. In much of the material used, these men and women are also the most recognisable and celebrated ‘heroes’. Consideration of the role of heroes in the formation of culturally constructed group identities informs the thesis, and the relationships between local sporting participants and groups are also important. Divisions, dissension, and competition for resources are all revealed in the reported activities of sports organisations, and changes in the importance afforded these endeavours are also apparent.
The focussed critical use of a local media source provides a consistent, if sometimes homogenous, group of historical narratives. The inclusion of local club and association histories, often produced with extensive use of newspaper archives, changes the perspective and enables a more nuanced examination of the place of different types of heroes, of gender norms and, most importantly, of the ways sporting organisations see and project themselves as part of the region. The stories they collectively choose to remember and tell are central to this narrative of the place of sport in the Waikato.
