title: Multi-label classification using boolean matrix decomposition

authors: Wicker, Jörg

subjects: Machine learning

abstract: This paper introduces a new multi-label classifier based on Boolean matrix decomposition. Boolean matrix decomposition is used to extract, from the full label matrix, latent labels representing useful Boolean combinations of the original labels. Base level models predict latent labels, which are subsequently transformed into the actual labels by Boolean matrix multiplication with the second matrix from the decomposition. The new method is tested on six publicly available datasets with varying numbers of labels. The experimental evaluation shows that the new method works particularly well on datasets with a large number of labels and strong dependencies among them.

title: The social work regulation project in Aotearoa New Zealand

authors: Hunt, Sonya

subjects: social work regulation

abstract: INTRODUCTION: In this second of two articles on the history of professionalisation of social work in Aotearoa New Zealand, consideration is given to the more recent coalescing of forces from the 1990s to the initial implementation of the Social Workers Registration Act (2003), which led to our country’s example of a social work regulation project. 
APPROACH: This critical consideration of social work regulation in Aotearoa New Zealand situates it within the international social work professionalisation context alongside the national context. Consideration is given to the place of leadership and buy-in from the profession, political sponsorship, cultural considerations, and another ministerial review. Overlaying this, an examination of concepts of public trust, respect, and confidence in professions such as social work, are linked to crises of trust in professions in general, and placed within the current neoliberal, market-driven environment in which this project is anchored. 
CONCLUSION: The literature serves to document the history of social work regulation in Aotearoa New Zealand and as background for an ongoing research project which aims to uncover interests at work and interrogate the legitimacy of those interests, while enabling the voices of key actors from the time to surface, be explored, and be recorded.

title: Popoia te reo kia penapena: Nurture the language

authors: Berryman, Mere

subjects: Maori language

abstract: Research to develop a Māori language screening tool (Specialist Education Services, 2001), identified that students entering Māori Medium at five, could be classified into one of four Māori language competency, groups. Concurrently, teachers raised their need to identify the Māori language proficiency of five year olds entering Māori Medium so that more appropriate teaching strategies could be incorporated in preparation for literacy.
Accordingly, three Māori oral-language assessment tools, to help identify the Māori language competency of students entering Māori Medium settings at five years of age and provide formative information, were developed in response to this need. This paper details the development and trial of these tools.
