title: The limitations of the methods of identifying the floral source of honeys

authors: Molan, Peter C.

subjects: biology

abstract: The pollen grains in honey reveal the types of plants that were around when the bees produced the honey, thus it is valid to use melissopalynology to determine the geographical origin of honeys, but there are several reasons why it is less valid for determining the botanical origin of honeys.

title: Testing a biologically-based system for extracting depth from brief monocular 2-D video sequences

authors: Perrone, John A.

subjects: Cameras

abstract: Knowledge of the 3-D layout in front of a moving robot or vehicle is essential for obstacle avoidance and navigation. Currently the most common methods for acquiring that information rely on ‘active’ technologies which project light into the world (e.g., LIDAR). Some passive (non-emitting) systems use stereo cameras but only a relatively small number of techniques attempt to solve the 3-D layout problem using the information from a single video camera. A single camera offers many advantages such as lighter weight and fewer video streams to process. The visual motion occurring in brief monocular video sequences contains information regarding the movement of the camera and the structure of the scene. Extracting that information is difficult however because it relies on accurate estimates of the image motion velocities (optical flow) and knowledge of the camera motion, especially the heading direction. We have solved these two problems and can now obtain image flow and heading direction using mechanisms based on the properties of motion sensitive neurones in the brain. This allows us to recover depth information from monocular video sequences and here we report on a series of tests that assess the accuracy of this novel approach to 3-D depth recovery.

title: Typographic design in Māori-English bilingual picturebooks: some educational implications

authors: Vanderschantz, Nicholas

subjects: Te Reo Māori

abstract: The role of bilingual picturebooks in language learning has been explored recently by a number of authors who show their potential in normalising multilingualism (Naqvi, Thorne, Pfitscher, Nordstokke & McKeough, 2013; Zaidi, 2020), raising metalinguistic awareness and engaging parents (Sneddon, 2009), as well as raising language awareness (Kleker, Short & Daly, 2021). Hadaway and Young (2013) suggest bilingual picturebooks have a particular role to play in supporting the revitalisation of Indigenous languages. In New Zealand, the number of MāoriEnglish bilingual picturebooks is increasing, but there is very little, if any, research concerning their design or their use in educational settings. The design of bilingual picturebooks, as reflected in their linguistic landscape, has an important role to play in their pedagogical use (Daly, 2016; 2017), and in this article, we explore the typographic design of five bilingual Māori-English picturebooks with respect to the elements of typeface, type size, type colour and page layout. We discuss the design and audience implications of these factors for educational settings.
