title: The parallel diffusion coefficient and adiabatic focusing of cosmic-ray particles

authors: Litvinenko, Yuri E.

subjects: cosmic rays

abstract: In this paper, the problem of focused particle transport is revisited. A description in terms of a system of stochastic differential equations, completely equivalent to the Fokker-Planck equation, is suggested. The coefficient for spatial diffusion parallel to the mean magnetic field is calculated. The case of isotropic pitch angle scattering and weak focusing is analyzed in detail. The disagreement between a recent analysis by Shalchi and other treatments of the same problem is discussed.

title: The power of stereotypes: Anchoring images through language in live sports broadcasts

authors: Desmarais, Fabrice

subjects: television

abstract: Televised sport offers a rich context for investigating the processes that influence particular uses of language. Here, the authors consider how pressure on sport commentators to connect with audiences results in reliance on preestablished narratives that draw heavily on stereotypes. They investigate how television sport commentators negotiate tensions between stereotypes of a particular country’s playing style and on-field action that challenges those stereotypes. Their interdisciplinary approach—drawing from social psychology, communication, media studies, sport studies, and cultural studies—provides a textual analysis of New Zealand commentary in a pivotal Rugby World Cup game between France and New Zealand. The authors identify three different ways in which national stereotypes lead commentators to produce interpretations that do not always accurately represent the action on the field. They conclude that sport commentary in an international context operates to create and reinscribe symbolic differences between nations, even in the face of visual evidence that is ambiguous or actively contradicts the words used to describe it. The analysis demonstrates how powerfully national stereotypes influence commentators’ representational choices.

title: Software development: Involving Tangata Whenua and incorporating Tikanga Māori

authors: Taia, Ivy

subjects: software engineering

abstract: Over the past fifty years, software development (SD) has been dominated by Western approaches, which is widely accepted as the standard way of doing things (Diaz Andrade et al., 2021). Consequently, many software applications for specific Indigenous cultures, especially health interventions and educational software (Dobson, Whittaker, Bartley, Connor, Chen, Ross & McCool, 2017; Fleer, 1989), were developed using traditional software engineering (SE) methodologies. Although these methodologies provide the workflows and methods for developing software, they do not provide guidelines for developing Indigenous software. While there have been numerous studies on diversity, such as gender and ethnicity in the field of Information Systems, there is very little research on the practices of involving Indigenous people and incorporating their traditional customs in the software development process. This thesis examines the participation of Indigenous people in software development. The research specifically focuses on Tangata Whenua (Māori people, the Indigenous population of Aotearoa New Zealand) and Tikanga Māori (Māori cultural methods). Our findings are useful to those attempting to enhance Indigenous representation in software development, especially those wanting to involve Māori people and their cultural methods in the development process and design of software.
