title: Social psychology and media: critical considerations

authors: Chamberlain, Kerry

subjects: psychology

abstract: In this paper, we argue that media saturate everyday living, and that people engage with and are engaged by media in diverse and complex ways. We suggest a need for an informed social psychology of media that conceptualises media as social practice, and attends to media practices as they occur. We propose that much media psychology research is limited because it: (i) focuses too strongly on documenting causal, and usually negative, media effects; (ii) continues to apply unsuitable research methodologies and theories to investigating media and ignores advances in media research and theory arising outside the discipline; and (iii) largely ignores the social contexts in which media engagements occur. These arguments are illustrated by studies that take a more social and critical approach to media research and that show possibilities for overcoming these limitations and developing insights into psychological concerns enmeshed in media practices.

title: Nutrients and eutrophication: introduction

authors: McDowell, Rich. W.

subjects: anthropogenic

abstract: Cultural eutrophication stimulated by anthropogenic-derived nutrients represents one of the most common forms of compromised surface water quality in many developed and developing countries (Schindler 2012). In fresh water, both nitrogen (N) and phosphorus (P) can potentially contribute to eutrophication (Carpenter et al. 1998). In lakes it is more common that excessive P inputs are the primary cause of eutrophication (Schindler 1977) although both global (Elser et al. 2007) and national surveys (Abell et al. 2011a) have increasingly highlighted excessive N inputs as an equal or more important cause. Debate on the relative roles of N and P limitation of lake phytoplankton is highly contentious, with a P-limitation paradigm (Schindler et al. 2008) challenged by those who contend that both P and N control are key elements of eutrophication management in freshwater systems (e.g. Conley et al. 2009; Scott and McCarthy 2010). Eutrophication of temperate estuaries and coastal waters is also common, but in contrast to fresh water, N is more commonly the controlling nutrient (Carpenter et al. 1998).

title: Piri Pāua: Mātauranga Māori and marine science approach to growth rate and length at maturity of pāua in the Bay of Plenty 2022-2024

authors: Paul-Burke, Kura

abstract: Pāua is a highly regarded taonga (culturally important) species. Mai i ngā Kurī ā Whārei ki Tihirau (the Bay of Plenty Regional Iwi Customary Fisheries Forum) raised concerns about the current state of pāua in Te Moana-a-Toi (Bay of Plenty). This project utilised localised intergenerational observations of population dynamics in traditional harvesting areas to assess pāua productivity in the Tauranga Moana Mātaitai Reserve in Tauranga and Te Rohe Moana o Ngāti Awa in Whakatāne. The project combined mātauranga Māori alongside marine science field methods.

Results were compared with previous iwi-led research at Tauranga in 2013 and Whakatāne in 2010. The pāua population in 2023 had declined by almost half in Tauranga but remained relatively consistent across all sites in Whakatāne. However, pāua were small sized in both locations, with less than 1% of individuals reaching the Minimum Legal Size (125 mm) for harvesting. Growth rate surveys were conducted in the wild at both locations from June 2023 to the end of May 2024 and identified pāua as slow growing and, as a result, sexually mature at smaller sizes than in other regions of Aotearoa New Zealand.
