title: Understanding how ableism impacts inclusion of autistic children in ECE in New Zealand

authors: Sharma, Silky

subjects: ECE

abstract: Research shows that, despite the promise of inclusive early childhood education (ECE) in national and international legislation, disabled children and their families are still marginalised in ECE (Lyons, 2021; Macartney, 2011, 2019; Purdue, 2009). Recent work in Critical Disability Studies (CDS) and Disability Studies in Education (DSE) has connected this ongoing marginalisation of disabled children to the bias associated with ableism. Ableism is influenced by the ideology of normalcy, which produces the notion of a ‘normal’ child, and simultaneously conceptualises a disabled child as ‘other’ in relation to their rights and participation. However, ableism and its impact on excluding disabled children and their families in ECE have been given little acknowledgement (Love & Beneke, 2021; Macartney, 2019). To address this gap, this study investigates whether and how ableism operates in an ECE setting in New Zealand, in order to understand its impact on the inclusion of autistic children and their families. Additionally, this study explores how disability awareness and critical reflection on their practices can help teachers support inclusive practices for autistic children. The study also analyses key policy documents in early childhood education and special education. 
 
 This study adopted the theoretical frameworks of Disability Studies in Education (DSE) and ableism. DSE challenges ableist ideologies and practices that dehumanise disabled children and focuses on the role of educational settings and broader society in supporting inclusion (Baglieri & Bacon, 2020). The research uses two data sets i) two policy documents, Te Whāriki (Ministry of Education (MoE), 2017) and Success for All (MoE, 2010), and ii) a case study within an ECE setting. The methods used to collect case study data included individual interviews with staff as well as a parent of an autistic child; video recordings and observations of interactions with autistic children in the ECE setting; a teachers’ focus group discussion; and analysis of documents written and used in the ECE setting. The analytical tools of thematic analysis and Fairclough’s (1995, 2003) approach of Critical Discourse Analysis (CDA) were used to identify the discourses of ableism within both data sets. The thesis examines how these discourses as social practices disrupted the inclusion of autistic children.  
 
The findings indicate evidence of ableism operating in ECE policies and interactions in the ECE setting via the dominant discourses of developmental psychology, the medical model of disability, special education, and neoliberalism, and indicate that these discourses inform disablist practices that negatively impact the inclusion of autistic children. The findings also highlight that disability awareness and providing space, time and collaborative support to teachers for critically reflecting on their practices can positively change their thinking towards autistic children and empower them to affect changes in their teaching. A key argument is that the theoretical understanding developed in this study draws attention to the importance of the DSE framework in recognising and challenging ableism and reorienting thinking around inclusion in ECE policy and practice. Accordingly, the study offers theoretical ideas that can be used to work against ableism and promote inclusive practice for autistic and other disabled children.

title: Prediction of ordinal classes using regression trees

authors: Kramer, Stefan

subjects: computer science

abstract: This paper is devoted to the problem of learning to predict ordinal (i.e., ordered discrete) classes using classification and regression trees. We start with S-CART, a tree induction algorithm, and study various ways of transforming it into a learner for ordinal classification tasks. These algorithm variants are compared on a number of benchmark data sets to verify the relative strengths and weaknesses of the strategies and to study the trade-off between optimal categorical classification accuracy (hit rate) and minimum distance-based error. Preliminary results indicate that this is a promising avenue towards algorithms that combine aspects of classification and regression.

title: A wiggle-match date for Polynesian settlement of New Zealand

authors: Hogg, Alan G.

subjects: East Polynesia

abstract: Dating initial colonisation and environmental impacts by Polynesians in New Zealand is controversial. A key horizon is provided by the Kaharoa Tephra, deposited from an eruption of Mt Tarawera, because just underneath this layer are the first signs of forest clearance which imply human settlement. The authors used a log of celery pine from within Kaharoa deposits to derive a new precise date for the eruption via "wiggle-matching" – matching the radiocarbon dates of a sequence of samples from the log with the Southern Hemisphere calibration curve. The date obtained was 1314 ± 12 AD (2σ error), and the first environmental impacts and human occupation are argued to have occurred in the previous 50 years, i.e. in the late 13th – early 14th centuries AD. This date is contemporary with earliest settlement dates determined from archaeological sites in the New Zealand archipelago.
