title: Breaking the Intergenerational Cycle of Physical Punishment

authors: Sturkenboom, Gina Alicia

subjects: physical punishment

abstract: Fifteen women and five men participated in a study aimed at devising strategies to reduce the use of physical punishment in New Zealand. The potential problems with the use of physical punishment, the extent of its use in New Zealand, and the likelihood of intergenerational transmission are discussed to justify the aim of the study. 

The participants were all parents who had been smacked themselves, but who had decided not to smack their own children. Their ages ranged from 28 to 57, and only three had less than some tertiary education. They were from various ethnic backgrounds; fourteen had an occupation other than parenting, and nine were single parents.

The participants had broken the intergenerational cycle of physical punishment: they had been smacked themselves but did not smack their own children. All participated in an individual, semi-structured interview, in which their childhood physical punishment, their decision not to smack, the maintenance of that decision, and their use of alternative disciplinary techniques were discussed. Four participated in a focus group, in which the strategies suggested in the interviews were discussed and refined to produce a final list of recommendations.
  
The parents made a conscious decision against smacking, which involved a particular experience that prompted them to consider their disciplinary practices. Negative views of smacking (ineffective, modelling violence, and potential to escalate) were also helpful in making the decision. 
 
While maintaining their decision was usually easy, alternative techniques were sometimes hard to use, though effective in the long term. Some had to deal with the effects of deviating from a childrearing norm, particularly in regard to other family members. While many were satisfied that their own children were free from physical punishment, some had actively tried to convince other parents not to use it as well. 
 
They recommended strategies aimed at achieving the goals of parent education, raising awareness, reducing strain, and increasing support for parents. They also suggested practical steps that individual parents who were interested in breaking the cycle of physical punishment could take. 

The limitations and strengths of the study are discussed, as well as the implications for further research. The study demonstrates that parenting without physical punishment is effective, desirable, and achievable, even by parents who were smacked themselves. It presents a number of possible strategies and intermediate goals, for interventions at a national, community, or individual level, which aim to reduce the use of physical punishment.

title: Evaluation of Cavitation Erosion Behavior of Commercial Steel Grades Used in the Design of Fluid Machinery

authors: Tzanakis, I.

abstract: The erosion response under cavitation of different steel grades was assessed by studying the erosion rate, the volume removal, the roughness evolution, and the accumulated strain energy. A 20 kHz ultrasonic transducer with a probe diameter of 5 mm and peak-to-peak amplitude of 50 μm was deployed in distilled water to induce damage on the surface of commercial chromium and carbon steel samples. After a relatively short incubation period, cavitation induced the formation of pits, cracks, and craters whose features strongly depended on the hardness and composition of the tested steel. AISI 52100 chromium steel showed the best performance and is, therefore, a promising design candidate for replacing the existing fluid machinery materials that operate within potential cavitating environments.

title: He raraunga inamata, he toronga ānamata, he huanga āke tonu atu: A multifaceted approach to improving quality of life for upper limb amputees

authors: August, Luke

subjects: Prosthesis

abstract: This thesis investigates innovative approaches to enhance the quality of life for upper limb amputees, integrating advanced prosthetic design, neurocontrol systems, and Māori knowledge systems. With the prevalence of prosthetic rejection and limitations in current designs affecting amputees' daily functionality and psychological well-being, a multifaceted strategy is essential. This research aims to address these challenges by improving prosthetic functionality, user control mechanisms, and incorporating cultural perspectives into prosthetic development.
The study first focuses on the design, development, and evaluation of four low-cost prosthetic hands. Assessing their Degrees of Freedom (DoF), Range of Motion (RoM), and Kapandji scores. The research proposes a novel hybrid coupled-tendon system. This system aims to combine the adaptability of underactuated designs with the precision control of coupled mechanisms, enhancing the prosthetic hands' functionality and grasp versatility.
In exploring control mechanisms, an EEG-based control system was developed to improve the intuitiveness of prosthetic control. Through comparative analysis of motor execution and action observation training regimes, facilitated by a digital twin, the study evaluates the efficacy of these methods in enhancing users' control over the prosthetics. The research identifies limitations in the classification of multiple active grasps and suggests potential improvements through augmented and virtual reality training environments. 
This thesis incorporates Māori perspectives by examining how mātauranga Māori can inform and enrich prosthetic design and usage. Through the analysis of pūrākau Māori, this work highlights the importance of considering the mauri, whakapapa of materials in prosthetic manufacturing and the implications of tapu on control systems. This inclusion aims to create culturally resonant devices that acknowledge and integrate the spiritual and cultural dimensions of the user's identity, offering a holistic approach to prosthetic development.
This interdisciplinary research contributes to the field by proposing a comprehensive framework that not only advances prosthetic technology but also aligns with cultural values and practices. By addressing the technical, psychological, and cultural needs of upper limb amputees, the project underscores the potential of combining engineering innovation with cultural wisdom to significantly improve amputees' autonomy and well-being. The findings advocate for a more inclusive and holistic approach to prosthetic development, emphasizing the importance of user-centric design and cultural competency in enhancing the quality of life for individuals with limb loss.
