title: River: Machine learning for streaming data in Python

authors: Montiel, Jacob

subjects: stream learning

abstract: River is a machine learning library for dynamic data streams and continual learning. It provides multiple state-of-the-art learning methods, data generators/transformers, performance metrics and evaluators for different stream learning problems. It is the result from the merger of two popular packages for stream learning in Python: Creme and scikit- multiow. River introduces a revamped architecture based on the lessons learnt from the seminal packages. River's ambition is to be the go-to library for doing machine learning on streaming data. Additionally, this open source package brings under the same um-brella a large community of practitioners and researchers. The source code is available at https://github.com/online-ml/river.

title: It’s a sign: From nocturnal kiwi to daytime heroes - The power of design in shaping conservation behaviour

authors: Fick-Swann, Skye

subjects: antecedent intervention

abstract: Interpretive signage is widely used in zoos and aquariums to support conservation education, yet evidence of its behavioural effectiveness remains inconsistent. I examined whether a poster designed using Big Hero Visualisation (BHV) principles functioned as an effective antecedent stimulus to increase recall of the five kiwi species. A between-subjects online experiment presented participants with existing National Aquarium exhibition signage, with the BHV kiwi poster included as an additional antecedent stimulus for the experimental condition only. The control condition viewed the same materials without the BHV poster prior to recall assessment. Participants also completed the Value Orientation Scale (VOS) and the New Ecological Paradigm (NEP) scale to explore whether self-reported environmental value orientations predicted recall or interacted with the signage condition. The logistic regression indicated that participants who viewed the BHV poster were more likely to recall the correct number of kiwi species compared to the control condition. None of the VOS or NEP subscales, nor their interactions with condition, were associated with recall accuracy. The study provides applied evidence that antecedent manipulations in visual design may influence immediate recall of conservation information. However, the online format likely increased attending relative to naturalistic settings, and I measured only immediate recall rather than broader behavioural outcomes. Future research should investigate how BHV elements perform amongst real-world competing stimuli and whether specific design components are more effective antecedent features. Overall, the results support continued evaluation of interpretive design as a low-cost behavioural intervention for improving conservation-related learning.

title: Maori Flourishing in a Fast Changing World - Inaugural Professorial Address

authors: Nikora, Linda Waimarie

subjects: Indigenous psychology; Maori flourishing; social identity; social and emotional wellbeing

abstract: A strong sense of who one is and that one’s life matters is vital to health and wellbeing. Without meaning and belonging many people, families and communities lie open to the risk of mental illness, addiction, transience, criminality, suicide and so on. In a rapidly changing social and technological environment where being Maori is enacted in the face of a dominant Pakeha majority, and in an increasingly diverse Maori world, staying well is an important challenge that we cannot underestimate or take for granted. There are many unwellness forces upon Maori in this fast changing world. Some are obvious and readily felt, others not so easy to apprehend or explain. Surveying almost 30 years of research, Professor Nikora will examine some of these unwellness forces and responses Maori make within the broader quest to remain indigenous and to flourish.
