‘The Other Parent’: A Critical Policy Analysis of Fatherhood Discourses in the Australian Government's Paid Parental Leave Scheme

Australian Journal of Social Issues, EarlyView.
ABSTRACT The Australian paid parental leave (PPL) government scheme aims to support working parents through financial assistance and the promotion of gender equality in caregiving responsibilities. However, the scheme's implementation has been critiqued for its gendered design, which marginalises fathers and reinforces traditional gender roles.

Durability assessment of mechanochemically activated geopolymer concrete with a low molarity alkali solution

Case Studies in Construction Materials
The prevailing practices of geopolymer concrete (GC) preparation use a high concentration of alkali activators, which is uneconomical. It is imperative to develop GC of low-concentration activators with enhanced durability for field implementation ...

Comparative study of the use of Ordinary Portland Cement (OPC), Portland Composite Cement (PCC) and Hydraulic Cement (HC) types in high quality concrete with an independent compaction system [PDF]

E3S Web of Conferences
One of the problems faced in the manufacture of high-strength concrete is the difficult workability, and the rising price of OPC and PCC cement. To overcome these problems, a self-compacting system is needed in concrete to make the workability easier to ...

Study of peak velocity of blasting vibration for raft foundation demolition based on MEA-BP algorithm

AIP Advances
In order to solve the problem of poor accuracy of blasting vibration prediction by the traditional Sadowski empirical formula and BP neural network, a model based on the mind evolutionary algorithm (MEA) is proposed for the first time to optimize the BP ...

Properties of concrete incorporating locally produced Portland limestone cement

Ain Shams Engineering Journal, 2018
Blended cements are increasingly being used in concrete to reduce the amount of clinker in the cement, thus achieving both economic and environmental gains. The use of limestone as a component of Portland cement is now common practice worldwide. Reducing

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

The beauty of experiential learning in anatomy

Anatomical Sciences Education, EarlyView.
Abstract Anatomy is a unique subject where one must learn by doing. This is achieved through a variety of methods like dissection, use of prosections, imaging, playful learning (crocheting structures, drawing, and painting organs), through functional movement like yoga or pilates, use of 3D plastic models or by immersing oneself in virtual or augmented
