title: Propositionalisation of Profile Hidden Markov Models for Biological Sequence Analysis

authors: Mutter, Stefan

subjects: computer science

abstract: Hidden Markov Models are a widely used generative model for analysing sequence data. A variant, Profile Hidden Markov Models are a special case used in Bioinformatics to represent, for example, protein families. In this paper we introduce a simple propositionalisation method for Profile Hidden Markov Models. The method allows the use of PHMMs discriminatively in a classification task. Previously, kernel approaches have been proposed to generate a discriminative description for an HMM, but require the explicit definition of a similarity measure for HMMs. Propositionalisation does not need such a measure and allows the use of any propositional learner including kernel-based approaches. We show empirically that using propositionalisation leads to higher accuracies in comparison with PHMMs on benchmark datasets.

title: A whole-school approach to developing resilience: Resources and suggestions for New Zealand schools

authors: Poultney, Rachel

subjects: Resilience

abstract: In learning and life, there will always be challenges, requiring resilience to overcome, adapt, and persist in the face of adversity. Resilience is a key aspect of mental health and lifelong learning, reflected in the vision, key competencies, and health-related elements of the New Zealand Curriculum (Ministry of Education, 2007). Working on the understanding that schools can and should help learners to develop resilience, this article shares a recent inquiry undertaken by a full primary school in New Zealand (NZ), as part of a Teacher-Led Innovation Fund (TLIF) project. The inquiry approach and main findings are outlined, along with resources, and suggestions for schools striving to build a shared understanding of resilience among teachers, students, and parents. Our inquiry attests to the power of a whole school approach to the learning of resilience, underpinned by relational connections, the language of resilience and cross-curricula integration, as well as informal learning.

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.
