SHPB Test and Microstructure Analysis on Ready-Mixed Concrete in Uniaxial Load and Passive Confining Pressure States

Shock and Vibration, 2019
Ready-mixed concrete has been used as a support in mine roadways, where the impact load of blasting excavation can cause damage to the concrete support of the roadway. However, limited studies are available on the effect of water content, storage period,

Measuring Child Disadvantage: Comparing Multidimensional and Socioeconomic Approaches for Predicting Developmental Outcomes

Australian Journal of Social Issues, EarlyView.
ABSTRACT Robust measurement of disadvantage is essential to identifying and addressing inequities in children's development. We tested how a multidimensional framework of child disadvantage performed relative to a traditional socioeconomic position (SEP) approach to predict developmental outcomes.

Reclamation Trend of Underground Construction

Procedia Engineering, 2016
Abstract The paper exposes the problems inducing to the active reclamation of underground space in large cities with established historical and architectural development as well as the problems associated its reclamation. Freed up space, as a rule, is transformed into new public spaces, parks and squares; there are new functional communications ...

‘Turkeys Cannot Vote for Christmas’: Why Epistemic Disobedience in an Anti‐Black World Matters

Australian Journal of Social Issues, EarlyView.
ABSTRACT Never in the history of global coloniality has the idea of epistemic disobedience been as important as in the 21st century. This is not only because the struggle for decolonisation has shifted from physical confrontation between the coloniser and the colonised into a battle of ideas but also because the former has deployed the idea of ...

Family Dispute Resolution in Australia: The Under‐Servicing of Indigenous, Migrant and Refugee Families Experiencing Family Violence

Australian Journal of Social Issues, EarlyView.
ABSTRACT Improving access to legal services for Indigenous, migrant and refugee women is critical to addressing family violence. In this context, Family Dispute Resolution (FDR) has long been discussed as a solution for separating families. This paper presents key findings of a research evaluation of an Australian Government $8.37 million pilot project
