title: Algar do Bom Santo: a Middle Neolithic necropolis in Portuguese Estremadura

authors: Carvalho, António F

subjects: Neolithic

abstract: A research project on the Algar do Bom Santo necropolis started in 2010. This paper presents a preliminary synthesis on the exhumed human population and a first insight into the funerary practices recorded during the site excavations in the 1990s, as well as palaeodiet reconstitutions.

title: Fish-finding Fido; Can domestic dogs (Canis familiaris) offer a solution for detecting an invasive freshwater catfish (Ameiurus nebulosus)

authors: Little, Lauren Amber

subjects: Scent detection

abstract: Invasive species now dominate many aquatic landscapes in most parts of the world, displacing native plants and animals by disrupting and altering ecosystems. The brown bullhead catfish (Ameiurus nebulosus) has been significantly correlated with regime shifts from macrophyte‐dominated clear water states to de‐vegetated turbid states, population declines of endemic species, and the disruption of food webs in New Zealand lakes. Conventional detection methods (e.g., visual surveys, fyke netting, electrofishing, and eDNA) for catfish are limited by their cost, invasiveness, time- consumption, and potential to be prone to error. Given that scent detection dogs are a well-established tool across a variety of fields, it was hypothesised that domestic dogs (Canis familiaris) may be able to detect the presence of catfish from water samples that have contained these fish. This could provide a new potential biosecurity monitoring tool.
In this study, five pet dogs were trained to operate an automated apparatus that presented water samples for evaluation. Water samples were presented to dogs from aquaria that had previously contained, catfish, goldfish (Carassius auratus), or no fish. Experiment 1 evaluated if dogs could discriminate between samples that had contained catfish or no fish. In Experiment 2, it was evaluated if dogs can discriminate between fish species (i.e., catfish and goldfish), and at what fish biomass concentrations they can do so. Experiment 3 evaluated if dogs could indicate the presence of catfish when samples were presented at two different biomass concentrations in the same session. It was found that dogs were able to correctly identify water that had contained catfish and largely reject water samples that had contained either no fish or goldfish at above 80% accuracy at biomasses equivalent to environmental biomasses of 4.6 x 1,000 kg/ha. Preliminarily investigations of lower detection limit thresholds were investigated in the study. These results suggest further investigation is warranted to confirm the dogs’ ability to detect catfish at biologically relevant concentrations comparable to real-world sample scenarios. However, these findings support the suggestion that dogs may have an important role to play in waterway conservation and management.

title: Manaaki whenua. Manaaki tangata: Care for the land, care for the people: Leading critical school reform with mana whenua and whānau Māori

authors: Ford, Therese

subjects: Critical school reform

abstract: Education disparities between Māori and Pākehā students in Aotearoa, have their origins in colonial education policies and practices which considerably advantaged Pākehā students and compromised the ability of Māori students to engage with learning and succeed.  Despite the promises of equality inherent in the Treaty of Waitangi,  this historical foundation has, for over 150 years, perpetuated intergenerational cycles of education failure for Māori resulting in high levels of endemic social and economic disadvantage in many Māori communities.
This thesis examines the leadership praxis of two Pākehā principals, to understand how, with more respectful connections with Māori communities, they were able to address education disparities and facilitate success for Māori students as Māori. Culturally responsive research methodologies guided two, in-depth case studies which employed mixed methods.
Two collaborative stories, with the voices of mana whenua and whānau Māori, identified the importance of school leaders developing critical levels of consciousness, through authentic, bidirectional relationships with Māori communities.  These relationships enabled the principals to understand the authentic local, pre-colonial iwi histories of the land. This in turn fostered connections between the schools and local Māori communities that enabled them to collaboratively respond to the implications of colonisation.  
The thesis challenges the monocultural, monolingual, unidirectional policies and practices that characterise the current model of colonial education.  It presents instead a decolonising model of critical school reform and a framework for implementation and evaluation.  It contends that honouring the Treaty of Waitangi requires an equity focused response with power sharing relationships, critically led by principals alongside Māori communities.
