title: Exploring a framework for matching to sample with visual stimuli in dogs (Canis familiaris)

authors: Arivazhagan Ambalam, Arihant

abstract: Dogs have been studied for their olfactory abilities, yet their capacity for same-modal visual matching to stimuli remains underexplored. Research focused on scent detection, and cross-modal odour matching. However, little attention was given to visual matchings. This study investigated dogs’ ability to match visual stimuli. Two monitors were used: one displaying a single image, and the other divided into four quadrants. Four dogs were trained to select the stimuli on the second monitor as displayed on the first. In the discrimination task, an errorless learning approach was implemented, where the correct stimuli were presented at full brightness while the incorrect shape was dimmed. As the stages progressed, the incorrect shape’s brightness increased. All dogs successfully matched to sample at low brightness, and they were able to perform better than chance. However, they didn’t meet the criteria to discriminate between shapes when both were presented at full brightness. After discontinuing errorless learning, the dogs went under a pure conditional discrimination test. Almost all dogs performed better than chance, while there were some significant findings specific to each dog. The findings contribute to understanding canine visual perception and contribute to a methodological framework for visual-visual matching tasks. Future studies may refine these methods to enhance canine performance in discrimination learning.

title: Supporting Remote Collaboration through Structured Activity Logging

authors: Bouamrane, Matt-Mouley

subjects: computer science

abstract: This paper describes an integrated architecture for online collaborative multimedia (audio and text) meetings which supports the recording of participants' audio exchanges, automatic metadata generation and logging of users editing interaction and also information derived from the use of group awareness widgets (gesturing) for post-meeting processing and access. We propose a formal model for timestamping generation and manipulation of textual artefacts. Post-meeting processing of the interaction information highlight the usefulness of such histories in terms of tracking information that would be normally lost in usual collaborative editing settings. The potential applications of such automatic interaction history generation range from group interaction quantitative analysis, cooperation modelling, and multimedia meeting mining.

title: The discovery of the Waiorongomai goldfield in 1881

authors: Hart, Philip

abstract: The first reports of gold being found in the vicinity of the Waiorongomai Stream were made in early November 1880, and after the opening of the goldfield a small rush took place to this part of the mountain. The first claims were pegged out in December and the following January, encouraged by some gold being found, but few claims were registered, for most prospectors were quickly disappointed. Prospecting was difficult because of the rugged terrain and heavy bush, and interest quickly faded.
Then, in early October, Hone Werahiko announced his latest and best find and provided samples of payable ore taken from a large reef. Immense excitement ensued, as this was the first payable reef to be found, and after Werahiko led miners on an exhausting trip to his ‘New Find’ a rush set in and many claims were pegged out. The first official to inspect the ground anticipated that the reefs could be easily worked, once an access track was constructed. The small settlement of Te Aroha was revived because a real goldfield had been found, at last.
