title: Cross-sectional and time-series momentum returns: are Islamic stocks different?

authors: Cheema, Muhammad A.

subjects: Social Sciences

abstract: We search for differences in both unconditional and conditional momentum returns of Islamic and Non-Islamic stocks and test implications of competing behavioural theories that aim to explain momentum returns. Our results show that there is no significant difference in momentum returns between Islamic versus Non-Islamic stocks with respect to both cross-sectional (CS) and time-series (TS) momentum strategies even when we condition momentum returns on market dynamics, information uncertainty and idiosyncratic volatility. We also find that the TS strategy outperforms (underperforms) the CS strategy in market continuations (transitions) consistent with the recent evidence in the U.S. market.

Furthermore, we find that CS and TS strategies of both Islamic and Non-Islamic stocks are profitable only when the market continues in the same state consistent with overconfidence driving momentum returns of both Islamic and Non-Islamic stocks.

title: Self-organising map analysis of rugby placekicking biomechanics

authors: Hébert-Losier, Kim

subjects: artificial neural network

abstract: Our aim was to use a self-organising map (SOM) to examine key biomechanical variables previously identified to discriminate best from worst placekicking attempts. Placekicker and ball 3D biomechanics were acquired from three competitive placekickers who performed 10 kicks outdoors, 35-m from the posts. Seven key variables were extracted for SOM analysis and kicks were categorised into "best", "typical", and "worst" for each placekicker based on kick outcomes and player and coach ratings. SOM output indicated that three clusters best explained intra-cluster similarities and inter-cluster differences. The three clusters highlighted differences between the biomechanical variables of the three placekickers rather than the best, typical, and worst kicks. Within-clusters, however, the best and worst kicks tended to be represented by nodes in separate map regions.

title: Investigating Māori approaches to trauma informed care

authors: Pihama, Leonie

subjects: Māori health and wellbeing

abstract: This article gives an overview of a three-year Health Research Council funded research project “He Oranga Ngākau: Māori approaches to trauma-informed care”. The study is informed by Kaupapa Māori which provides both the theoretical and methodological foundation for understanding the world, exploring and conceptualising issues. The need for contextualised and culturally safe health and social services is well recognised within Aotearoa and particularly within Mental Health and Addiction Services. While trauma is an experience that can impact on all people, Māori experience trauma in distinct ways that are linked to the experience of colonisation, racism and discrimination, negative stereotyping and subsequent unequal rates of violence, poverty and ill health. Given that Māori are impacted by trauma in specific ways, it is important to explore and identify practice principles that contribute to the development of a framework that supports Māori Providers, counsellors, clinicians and healers in working with Māori. (Authors' abstract).
