title: Beneath the Golden Facade: A History of the Early Years on the Thames Goldfields

authors: Johnson, Matthew Alan Barker

subjects: Thames

abstract: The story of Thames has been told and retold by many authors since the area was proclaimed a goldfield in 1867. These histories often glamourise the prosperity and wealth that gold brought to the town and its people. This thesis argues that this was not the case. In fact, the goldfields struggled for many years because the area lacked the necessary equipment to extract the gold. By 1870, machinery was steadily introduced and implemented, leading to short period of prosperity in the town, but it was temporary. Throughout the late 1860s and 1870s, locals experienced many financial hardships, which have been neglected by historians in favour of more positive portrayals of life on the goldfields. This thesis explores the economic situation of the town during this period, highlighting the experiences of those that failed to strike it rich on the goldfields. By examining their stories, it is clear that the romantic portrayal of life in early Thames was in the most part fiction compared to the harsh realities of those actually living on the goldfields.
Additionally, this thesis examines the role that the community played in improving the economic situation in Thames. The efforts of locals helped to develop and foster a diverse array of industries, which lessened the town’s reliance on the success of the goldfields. These improvements came at a time when Thames was suffering considerable economic pressures, thanks in large part to the decline in gold production after 1871.
This thesis utilises a range of primary and secondary sources to investigate the economic situation of Thames during this early period. It makes thorough use of newspaper articles, which highlight what information was readily available to local and external observers pertaining to the condition of the town. Government reports are used to show the role that officials played in the development of Thames and what actions they took to improve the local economy. This thesis also examines personal accounts from residents, which illustrate the harsh realities of life on the goldfields.

title: The online performance estimation framework: heterogeneous ensemble learning for data streams

authors: van Rijn, Jan N.

subjects: Science & Technology

abstract: Ensembles of classifiers are among the best performing classifiers available in many data mining applications, including the mining of data streams. Rather than training one classifier, multiple classifiers are trained, and their predictions are combined according to a given voting schedule. An important prerequisite for ensembles to be successful is that the individual models are diverse. One way to vastly increase the diversity among the models is to build an heterogeneous ensemble, comprised of fundamentally different model types. However, most ensembles developed specifically for the dynamic data stream setting rely on only one type of base-level classifier, most often Hoeffding Trees. We study the use of heterogeneous ensembles for data streams. We introduce the Online Performance Estimation framework, which dynamically weights the votes of individual classifiers in an ensemble. Using an internal evaluation on recent training data, it measures how well ensemble members performed on this and dynamically updates their weights. Experiments over a wide range of data streams show performance that is competitive with state of the art ensemble techniques, including Online Bagging and Leveraging Bagging, while being significantly faster. All experimental results from this work are easily reproducible and publicly available online.

title: Just take a second to breathe: Empowering youth through mindfulness at Atawhai 2019

authors: McAllister, Suzanne Maree

subjects: Mindfulness

abstract: This research was an evaluation of The Kindness Institute’s 2019 Atawhai programme. It examined the effects that exposure to mindfulness-based skills, Māori cultural practices, mentoring, and the creative arts had on a cohort of marginalised youth. Specifically, the research aimed to determine (1) if learning mindfulness-based skills helped the youth to positively deal with challenges, (2) what effect learning mindfulness-based skills has on their positive and negative emotions and (3) were youth empowered to share the skills they learned within their homes, families and communities to enable a wider benefit from the mindfulness-based skills. Participants included 12 youth who attended the Atawhai programme during 2019. They all completed shortened versions of the Five Facet Mindfulness Questionnaire (FFMQ), Adolescent Self-Regulatory Inventory (ASRI), The Oxford Happiness Questionnaire (OHQ), Revised Children’s Anxiety and Depression Scale (RCADS) and Self-Compassion Scale (SCS) at seven stages over a nine-month period from March 2019 to December 2019. Self-report debrief questionnaires and researcher observations were recorded during the October 2019 residential intensive of 5 days. Inferential statistics (repeated measures ANOVA and post-hoc paired t-tests) indicated a statistically significant increase in positive emotions (p<0.01) with a large effect 1.07 over the duration of the evaluation period from March 2019 to December 2019; the October 2019 intensive, p<0.01, d=1.37; and the April 2019 intensive, p<0.01, d=1.89. Statistically significant decreases in anxiety (p<0.01) with a large effect d=1.99 were indicated over the duration of the evaluation period from March 2019 to December 2019; the October 2019 intensive, p=0.07, d=0.57; and the April 2019 intensive, p≤0.01, d=1.19. Self-report measures indicated the youth; found the mindfulness-based skills beneficial, preferred a particular skill over others, and found their mentors supportive in helping them incorporate the skills into their daily lives. Youth reported they had continued their mindfulness-based practice outside Atawhai and were regularly sharing the skills within their homes, families and communities including their schools. These findings suggest the Atawhai programme has a profound and significant positive effect on the wellbeing of the young people it serves.
