title: Design of a Stable Traffic Cone

authors: Wang, Chung-Fu(Chris)

subjects: traffic cone

abstract: Traffic cones are a common sight on roads in most countries but due to their commonplace nature people tend not to think too much about their design and the importance of them in maintaining safe traffic flow is often overlooked. Traffic cones have become a product that is taken for granted in daily life for most people. Traffic cones are so easy to see on the road and yet are readily neglected by people. Never the less traffic cones are still important for safety and guiding traffic flow even though they are so simple.

A traffic cone consists of a relatively thin walled cone above a square hollow base. In order to increase the cones stability, the base is usually weighted therefore lowering the centre of gravity of the entire traffic cone. Traffic cones are typically produced in plastic or composite materials for reasons of safety and cost.

A literature search of a range of books and professional magazines has turned up little related research and few reports on the topic of traffic or road cones. It appears that road- cones receive little attention by people, due to their simple profile and inexpensive production cost.

Most current products are designed with a considerable amount of weight in the base in order to increase the stability of the traffic cone, which consumes a relatively large amount of material. Stability cannot be significantly increased using this design strategy without increasing the amount of material and the cost of production. Therefore optimization of the design to improve flexibility and stability would be investigated without compromising the appearance or manufacturing costs.

title: New development and trends in mathematics education at pre-school and primary level

authors: Jones, Graham

subjects: education

abstract: TSG 1 had a broad focus, calling for papers that examined contemporary developments in mathematics education at the preschool and primary level (approximately ages 0 through 12 years). This provided an exciting opportunity to explore issues across the early childhood and school sectors and the team quickly decided to integrate early childhood and school presenters, with sessions organized around common themes, rather than by sector. The range of nationalities of the presenters and the participants in this group also allowed the ideas to be considered as they applied in a number of different contexts. This report highlights the themes that were considered, describes the papers that were presented, and summarises some of the key ideas and issues that arose in the group’s discussions.

title: Mana motuhake ā-raraunga: datafication and social science research in Aotearoa

authors: Kukutai, Tahu

abstract: Social practices, interactions and relations are increasingly being turned into data, driven by technologies that enable new methods of data accumulation, digitisation, integration and manipulation (Taylor and Broeders 2015; Couldry and Yu 2018; Mann and Daly 2019). This ‘datafication’ is not only transforming social relations, it is also reshaping social science through the generation of datasets that open up new avenues for research and methodological development (van Dijck 2014) and generating debate about the relationships between data, digitalisation, ethics and human wellbeing (boyd and Crawford 2012; Mittelstadt and Floridi 2016; O’Neil 2016; Eubanks 2018).
