title: Numerical simulations of wave setup over barred beach profiles: Implications for predictability

authors: Sephens, Scott A.

subjects: wave transformation

abstract: Numerical simulations of cross‐shore wave transformation and associated wave setup were performed for 100,000 realistic combinations of wave height, period and beach profile. Results of numerical simulations were compared to a widely‐used empirical predictor of wave setup and the outcome was a large variability in setup relative to that calculated by the empirical predictor. The variability, comparable in magnitude to the scatter around the empirical predictor developed with field observations, arose from unaccounted‐for wave energy dissipation over the cross‐shore profile. The beachface slope commonly used in empirical predictors can be a poor descriptor of wave transformation across the beach profile where most of the wave energy dissipation and setup generation occurs. Shoreline setup appears to be far more dependent on accurate characterisation of the offshore profile (e.g. bar location and depth) than the beach face slope.

title: Intersectional feminist and queer geographies: a view from 'down-under'

authors: Johnston, Lynda

subjects: Social Sciences

abstract: Despite rapid growth of geographies of genders and sexualities over the past decade, there is still a great deal of homophobia, transphobia, and heterosexism within academic knowledges. A queer and feminist intersectional approach is one way to highlight gendered absences, institutionalized homophobia and transphobia. To understand the diversity of genders and sexualities, feminist and queer geographers must continue to talk about, for example, genders (beyond binaries), sex, sexualities, bodies, ethnicities, indigeneity, race, power, spaces and places. It is vitally important to understand the way that genders and sexualities intermingle incommunity group spaces, rural spaces, and within indigenous spaces in order to push the boundaries of what feminist and queer geographers understand to be relevant sites of queer intersectionality. Reflecting on the production of queer and feminist geographical knowledges ‘down-under’ may prompt others to consider the way place matters to intersectional feminist and queer geographies.

title: Māori, census 2018 and data sovereignty

authors: Kukutai, Tahu

abstract: This webinar explores the issues with the 2018 Census data collection and examines what the implications could be for communities and funding.  See below to read some relevant articles prior to the webinar.

Our presenters also discuss iwi data sovereignty and data bias and the reasons why we should all pay more attention to the quality of the data we provide, use and collect.
