title: Deferral classification of evolving temporal dependent data streams

authors: Mayo, Michael

subjects: computer science

abstract: Data streams generated in real-time can be strongly temporally dependent. In this case, standard techniques where we suppose that class labels are not correlated may produce sub-optimal performance because the assumption is incorrect. To deal with this problem, we present in this paper a new algorithm to classify temporally correlated data based on deferral learning. This approach is suitable for learning over time-varying streams. We show how simple classifiers such as Naive Bayes can boost their performance using this new meta-learning methodology. We give an empirical validation of our new algorithm over several real and artificial datasets.

title: An Investigation of the Communal and Individual Resilience of Immigrant Women in New Zealand

authors: Okuyama, Lucinda

subjects: Resilience

abstract: Some immigrant women face triple discrimination due to their, gender, ethnicity and immigrant status. The voices of immigrant women are absent from literature on immigration, furthermore the experience of immigrant women are omitted as prominent literature largely presents the male immigration experience. In addition, immigrant women have been pathologised as much of the psychological literature views them through a deficit perspective, affirming that immigrant women are at risk of psychological disorders such as depression, anxiety and post-traumatic stress. This research adopts a strengths perspective in order to investigate resilience of immigrant women in New Zealand. This research explores the communal and individual resilience of immigrant women using a feminist qualitative framework. The women were interviewed by means of semi-structured, in depth interviews and the data was analysed by means of thematic analysis in order to report the experiences, meanings and realities of immigrant women’s lives. The analysis revealed that collective roles such as the role of mother, “co-madre”, the benevolent woman, the breadwinner and the role of spirituality and religious beliefs contributed to the resilience of immigrant women. It was also found that individual constructs such as individual spirituality, the emergence into a contemporary paradigm that allowed women to break free from traditional life, as well as the establishment of identities of independence and empowerment aided women’s resilience. The findings highlighted the complex and contradictory nature of immigrant women’s stories presenting a challenge to the pathology discourse of immigrant women evident in the literature and within society.

title: Safety hubs and partnership policing: Coordination, collaboration and partnership working in Auckland city centre

authors: Tompson, Lisa

subjects: Community Safety

abstract: This report presents key insights from an exploratory study of the Safety Hub initiative that first appeared in the run up to the 2023 Women’s World Cup in Auckland. It highlights the potential and the pitfalls of partnership-based approaches to community safety in Aotearoa New Zealand. The study was based on a series of in-person focus group discussions and semi-structured interviews with key partners and stakeholders including Community Patrols New Zealand (CPNZ) volunteers, NZ Police (Auckland city Beat officers and Liaison staff), Auckland council staff and Ngā Watene Māori (Māori Wardens). Data collection for this study took place over a four-month period from November 2024 through to February 2025, structured around the availability of participants. The study employed a thematic analysis methodology to systematically identify and organise key themes and issues within the qualitative data gathered from interviews and focus groups.
In summary, the operational reality of the Safety Hub was rather less structured and more ‘organic’ than some participants had hoped, but it still delivered meaningful outcomes. The Safety Hub made its own valuable contribution to community safety while the difficulties it faced helped identify the need for a wider, linked-up ecosystem of community safety in Auckland city. The Hub has proved itself to be a viable concept, that diverse partners can work together in a shared space, and that the presence of volunteers does offer reassurance and can make people feel safer. However, those involved in the Hub also identified a range of challenges that need to be overcome if the Hub is to be more than just a base for increasing the visibility and presence of capable guardians.
