title: Prevalence and risk factors for musculoskeletal pain when running during pregnancy: A survey of 3102 women

authors: Wyatt, Hannah E.

abstract: Background: Musculoskeletal pain while running is a concern to women during pregnancy and can lead to running cessation. To support women who wish to run during pregnancy, it is essential to understand the sites, severities and personal risk factors associated with musculoskeletal pain. Objective: The aim was to investigate prevalence and risk factors for musculoskeletal pain when running during pregnancy. Methods: An online survey was completed by women who had a child in the past 5 years and ran prior to and during pregnancy. Pain frequency informed prevalence rates by body site, and logistic regression odds ratios (ORs) and 95% confidence intervals were calculated. Results: A total of 3102 women of 23 ethnicities from 25 countries completed the survey. Women were 22–52 years old when they gave birth and ran 2–129 km/week during the 0.5–35 years before the birth of their youngest child. Women ran significantly less distance and less often during pregnancy than before pregnancy. Most women (86%) experienced pain while running during pregnancy (59% pelvis/sacroiliac joint, 52% lower back, 51% abdomen, 44% breast, 40% hip). The highest prevalence of severe-to-worst pain was at the pelvis/sacroiliac joint (9%). Women at greatest risk of pain while running during pregnancy had a previous injury (OR = 3.44) or were older (OR = 1.04). Women with a previous child were less likely to experience breast pain (OR = 0.76) than those running during their first pregnancy. Conclusion: Healthcare practices to reduce pain should focus on regions of greatest musculoskeletal change during pregnancy, specifically the pelvis, lower back and abdomen. Efforts to support women to run for longer throughout pregnancy should focus on pain at the pelvis and breasts.

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: KAUMĀTUATANGA  Supporting School Leaders To Develop Cultural Values While Resisting The Dominance of Colonialism

authors: Nuri, Ngahuia

subjects: Kaumātua

abstract: In an education system that is asserting to the importance of Māori (indigenous people of Aotearoa) language, culture, identity and the history of Aotearoa  (New Zealand) into the curriculum, there is direction from the Ministry of Education (MOE) for schools to reach out to iwi. What this looks like and how this can be achieved is not an easy task. This thesis follows the journey of three kaumātua (respected, knowledgeable elders, both female and male) working alongside the Senior Leadership Team (SLT) of a decile 10 kura auraki (mainstream primary school) where ākonga Māori (Māori students) were in the minority. The research examines what role kaumātua might have in guiding other schools to help tamariki Māori (Māori children) enjoy and achieve education success as Māori. It highlights the coming together of leaders from two different worldviews with this vision as a common purpose. 

Kaumātua in te ao Māori (the Māori world) are respected elders. Kaumātua are leaders, respected for their wisdom, knowledge and models of behaviour among other attributes. The Māui narratives are one example of demonstrating the characteristics of kaumātua. It was through his respected elders that Maui achieved so much. It was his grandfather who rescued him and taught him all he knew. It was his grandmother Mahuika who gave him fire and it was his kuia (female elder) Murirangiwhenua from whom he received the magic jawbone. The wisdom of Māori kaumātua has been recognised for centuries by Māori and yet kaumātua are often an untapped resource in the mainstream sector of education. In this thesis the kaumātua and members of the SLT share their experiences of working together and the learning and unlearning that has taken place over a period of four years from 2016 through 2019. They share their vulnerability, humility and strength in the goals they have worked towards over this period of time.
