Enactments of change: becoming textually active at youthline NZ

The phones at Youthline (NZ) hardly ring anymore. Young people still have problems, and are still helped, but it happens silently. This thesis addresses how counselling changes when mediated by technology, specifically text messaging. With emphasis on ‘moral purposing’, what it is to do good in contemporary counselling is explored.

Follower perceptions of the emotional intelligence of change leaders: a qualitative study

We present and explore a follower-centric model of how employees perceive the emotional intelligence (EI) of change leaders. Qualitative investigations of EI are rare and have not explored the field of organizational change leadership. Accordingly, we analyse qualitative data from a series of interviews set within the context of organizational change. We examine follower attributions about the abilities of their leaders to manage and express their own emotions and to respond appropriately to the followers' emotions. The findings reveal that the ways in which leaders deal with emotion might be the key to followers sharing their own emotions with them. The impact of perceived leader EI on follower responses to change is also discussed. The complexity and ambivalence of our participants' perceptions of the EI of their change leaders highlight the utility of a qualitative investigation. © The Author(s) 2011.

Indigenous students' persistence in higher education in Australia: contextualising models of change from psychology to understand and aid students' practices at a cultural interface

The need to address the substantial inequities that exist between Indigenous and non-Indigenous Australians in higher education is widely recognised. Those factors that affect the performance of Indigenous students in tertiary education have been reasonably well documented across different institutions, disciplines, and programme levels but there has, to date, been less consideration of the processes by which Indigenous students either persist or desist in higher education. This paper aims to present a conceptual understanding of academic persistence that can inform the delivery of tailored academic support interventions to Indigenous students who are at high risk of leaving higher education.

Effect of genotype and sex on fiber growth rate of alpacas for their first year of fleece production

The sale of alpaca fiber is the main income for thousands of families in the Central Andes of Peru. Little information exists on the fiber length growth rate of alpaca (FLG), especially throughout their first year of life when the fiber is most valuable. We aimed to determine the monthly FLG of 22 alpaca offspring of two genotypes (9 Suri, 13 Huacaya) and considering sex differences (10 females, 12 males) in the High Andes of Peru. FLG growth was determined using dye-bands. An additive lineal model with three factors (genotype, sex, month) was used for statistic analysis. To evaluate the effect of genotype and sex on the profile of the FLG throughout the year a two factor repeated-measures model was used. The results showed that FLG was affected by genotype and month but not sex. The Suri genotype had 20% higher FLG than Huacaya genotype alpacas (1.34 vs 1.10 cm/month, P < 0.001). FLG increased over each of the first three months (P < 0.05) and then maintained a near constant rate for the remainder of the first year. The resulting staple length indicates that shearing at ages from 8 to 12 months of age will provide fleeces of sufficient length for textile processing.

A decade of change in Australia’s DBA landscape

Purpose – The purpose of this paper is to examine the dynamics of the Doctorate of Business Administration (DBA) in Australia through the lens of a changing higher education landscape. The paper reflects on issues raised in a previous analysis of DBA programmes undertaken a decade ago, and highlights persistent challenges and emerging opportunities for professional Doctorate programmes in the Australian context.Design/methodology/approach – Interviews were undertaken with higher degree research directors, deans of graduate schools, and DBA programme directors from all 18 Australian institutions offering the DBA in 2013. Quantitative data on enrolments, accreditation requirements, course structures; and demographics are contextualised within a qualitative view of programme purposes, student and institutional motivations, rationales and concerns. Particular focus is given to perceptions of the difference between traditional research doctorates (PhDs) and professional doctorates, especially the DBA.Findings – In the decade from 2003 to 2013 DBA enrolments are down but enquiries are up, indicating unmet demand. There is a shift in the players, with some smaller, regional universities dramatically increasing their enrolments, and larger, traditional institutions exiting the space altogether. Significant changes in accreditation criteria have generated a perceptual shift: where DBAs previously suffered from “academic snobbery” regarding their legitimacy, this perception is being challenged by standards which require DBA equivalence with a PhD. This shift in standards has also created some confusion amongst supervisors and candidates.Originality/value – There is limited research into the DBA award or its candidates, and academic literature is generally silent on DBA supervision. This piece of research, one of very few that specifically examine the DBA, reflects on the past decade, analyses the present context and identifies emerging issues for the delivery of DBA programmes in Australia.

Scaling up the production rate of nanofibers by needleless electrospinning from multiple ring

Mass production of nanofibers is crucial in both laboratory research and industry application of nanofibers. In this study, multiple ring spinnerets have been used to generate needleless electrospinning. Multiple polymer jets were produced from the top of each ring in the spinning process, resulting in thin and uniform nanofibers. Production rate of nanofibers increased gradually with the increase of the number of rings in the spinneret. Spinning performance of multiple ring electrospinning, namely the quality and production rate of the as-spun nanofibers, was dependent on experimental parameters like applied voltage and polymer concentration. Electric field analysis of multiple ring showed that high concentrated electric field was formed on the surface of each ring. Fiber diameter together with production rate of needleless electrospinning was dependent on the strength and distribution of the electric field of the spinneret. Needleless electrospinning from multiple ring can be further applied in both laboratory research and industry where large amount of nanofibers must be employed simultaneously. © 2014 The Korean Fiber Society and Springer Science+Business Media Dordrecht.

Mediators of change in children's physical activity.

 The thesis has provided a more in-depth understanding of the causal mechanisms of behaviour change, specifically through identification of potential mediators as well as identification of challenges implementing effective intervention strategies targeting these mediators. A better understanding of these mechanisms is likely to enhance the effectiveness of future physical activity interventions.
