title: Perched and leaky layers in complex surface-subsurface flow environments: the Kawerau shallow groundwater aquifer (New Zealand)

authors: Shokri, Ali

subjects: perched and leaky

abstract: Perched and leaky geological layers can play an important role in hydrological systems by redirecting land surface recharge and reducing total recharge volume to regional aquifers. The extent of continuity and permeability of perched layers can be key physical parameters in surface and subsurface flow connection to regional groundwater systems. A semi-permeable perched layer with discontinuities, heterogeneity, fractures and faults will inevitably increase the spatial complexity of local recharge in an otherwise simple system. Relatively little is known about how perched and leaky layers might control linkages between surface flow, shallow groundwater flow, and regional groundwater. We describe one such system in the Kawerau shallow groundwater aquifer (New Zealand), where a thin, semi-permeable and fractured layer alternates between leaky and perching behaviour. A numerical groundwater model indicates the perching layer plays a critical role in controlling the volume and spatial pattern of water exchange between surface water and local and regional groundwater systems.

title: COVIDiSTRESS diverse dataset on psychological and behavioural outcomes one year into the COVID-19 pandemic

authors: Blackburn, Angélique M.

abstract: During the onset of the COVID-19 pandemic, the COVIDiSTRESS Consortium launched an open-access global survey to understand and improve individuals’ experiences related to the crisis. A year later, we extended this line of research by launching a new survey to address the dynamic landscape of the pandemic. This survey was released with the goal of addressing diversity, equity, and inclusion by working with over 150 researchers across the globe who collected data in 48 languages and dialects across 137 countries. The resulting cleaned dataset described here includes 15,740 of over 20,000 responses. The dataset allows cross-cultural study of psychological wellbeing and behaviours a year into the pandemic. It includes measures of stress, resilience, vaccine attitudes, trust in government and scientists, compliance, and information acquisition and misperceptions regarding COVID-19. Open-access raw and cleaned datasets with computed scores are available. Just as our initial COVIDiSTRESS dataset has facilitated government policy decisions regarding health crises, this dataset can be used by researchers and policy makers to inform research, decisions, and policy.</jats:p>

title: The arguing genre and the explaining genre: A comparison in terms of discourse relational analyses of texts written in English and texts written in Māori

authors: Crombie, Winifred

subjects: Māori linguistics

abstract: There is a commonly held belief that those who are immersed in indigenous cultures have a tendency, when constructing academic texts, to avoid sequential, deductive argumentation. We report here on a comparison of two groups of texts exhibiting two different genres - 'explaining' and 'arguing'. One group of texts was written in Māori by indigenous authors, the other group was written in English by non-indigenous authors. Our findings are that although the percentage use of logico-deductive relationships is roughly equivalent for both groups of texts/ writers in the case of the explaining genre, the Māori texts/ writers use almost twice the percentage of logico-deductive relationships as do the English texts/ writers.
