title: Future trends in I&M: The next generation of measurement technology for medicinal cannabis production

authors: Ooi, Melanie Po-Leen

abstract: Across the globe, legislation surrounding the application of cannabinoid compounds towards human health is gaining momentum. Corresponding with new regulations is a dramatic increase in cannabinoid-based treatment options—from just a few drugs in the early 2000s to now over 300 medical products currently in human trials for ailments such as post-traumatic stress disorder, nervous system degeneration, depression, epileptic seizures, Parkinson's disease, multiple sclerosis and schizophrenia. Consumption of medicinal cannabis is currently legal in over 40 countries and 33 states in the US, with the global sector estimated by some industry analysts to be worth over USD 62.6 billion by 2024 [1]. Legalization of medicinal cannabis is under consideration in over a dozen other countries, and more jurisdictions can be expected to follow suit if the evidence for efficacy of medicinal cannabis increases.

title: Adaptive XGBoost for evolving data streams

authors: Montiel, Jacob

subjects: computer science

abstract: Boosting is an ensemble method that combines base models in a sequential manner to achieve high predictive accuracy. A popular learning algorithm based on this ensemble method is eXtreme Gradient Boosting (XGB). We present an adaptation of XGB for classification of evolving data streams. In this setting, new data arrives over time and the relationship between the class and the features may change in the process, thus exhibiting concept drift. The proposed method creates new members of the ensemble from mini-batches of data as new data becomes available. The maximum ensemble size is fixed, but learning does not stop when this size is reached because the ensemble is updated on new data to ensure consistency with the current concept. We also explore the use of concept drift detection to trigger a mechanism to update the ensemble. We test our method on real and synthetic data with concept drift and compare it against batch-incremental and instance-incremental classification methods for data streams.

title: Kaum tuatanga the changing roles of kaum tua in Ng ti Rehua: Future directions

authors: Davies, Sydney Henare

subjects: Indigenous psychology

abstract: This study looks at the roles of kaum tua and investigates how these roles have changed over time. With the ageing Māori population and the reported importance of kaum tua roles in the wellbeing of Māori communities, the findings of this study provide an insight into the possible future direction of these roles. The study was conducted with the assistance of members of one hapu (N=47) that were 65 years of age and over. The study was by interview, utilising a semi-structured questionnaire with both open ended and closed questions. Narratives from participants was analysed and compared to the roles of kaum tua that were found in the literature, namely; Leadership, cultural knowledge, dispute resolution, protection and nurturing of young, provide spiritual and other guidance, social control, provide rituals, preserve te reo Māori and live active and healthy lives. Findings of this research supported the roles found in the literature. The roles of kaum tua still exist but may have diminished over time. The change in roles is in the adaptation to meet the needs of the time period while maintaining the core values of each role and providing a continuation of practices.
