title: How an exchange of perspectives led to tentative ethical guidelines for visual ethnography

authors: Pope, Clive C.

subjects: visual ethics

abstract: Qualitative research, especially visual ethnography, is an iterative not a linear process, replete with good intentions, false starts, mistaken assumptions, miscommunication and a continually revised statement of the problem. That the camera freezes everything and everyone in the frame only complicates ethical considerations. This work, jointly authored by the researcher, the Research Ethics Committee (REC) chair and an informed outsider, walks the reader through the ethical challenges the researcher experienced seeking REC approval to conduct a visual ethnography of a secondary school's rowing event. Eventually, the researcher found the challenges and ambiguities of informed consent indicative of the current issues facing many researchers working with the visual medium. The account fleshes out a procedural ethics and ethics in practice dichotomy and ends with the researcher and REC chair retrospectively contemplating the iterative ethics of visual ethnography. We conclude our conversation by proposing five tentative guidelines for visual ethnography researchers and their research ethics committees.

title: Misconceptions arising from the Infinite Solenoid Magnetic Field Formula

authors: Wilson, Marcus T.

abstract: Many high school and first-year university courses include discussion of the magnetic effect of currents. Frequently discussed textbook examples include long, straight wires, circular current loops, and solenoids, partly because these examples are tractable mathematically. The solenoid naturally leads to discussion on magnetic materials since it is readily demonstrated that a paramagnetic core significantly boosts the strength of an electromagnet. However, magnetic effects of solid and even liquid materials are subtle and confusing¹ and the mathematics is not straightforward. This leads to confusion amongst students (and their teachers), which, when taken to more advanced study, leads to significant misconceptions about the nature of magnetic properties and fields. These misconceptions can become problematic when practical (rather than stereotyped) magnetic design and analysis is required such as for transformers,² magnetic recording materials, geomagnetic sensors,³ or biological stimulators4 to name a few. In this article, I highlight examples of this confusion, in particular the failure in realistic situations of the well-quoted formula for an infinite solenoid with a paramagnetic core, and the physical interpretation of the relative permeability of a material, µr.

title: The Māori Data Privacy Framework: How useful is it for hapū?

authors: Clark, Vanessa

abstract: This brief is a part of a series, produced for the Tikanga in Technology (TiNT) research programme, that provides a hapū perspective on data sovereignty, data governance, and data privacy. In this brief we focus on the Māori Data Privacy Framework developed by the TiNT team and assess how useful it is for hapū. To do so, we draw on a case study with Ngāti Tiipa, one of the 33 iwi and hapū of the Waikato confederation (Kukutai, Whitehead & Kani, 2022). This brief should be read in conjunction with TiNT Brief #2 Protecting hapū data privacy: A Ngāti Tiipa case study of technology considerations.
