Fighting, anger, frustration and tears: Matthew's story of hegemonic masculinity

This paper draws on Matthew's story to illustrate the conflicting discourses of being a boy and being a student. Matthew is 12 years old and in Grade Six, his final year at Banrock Primary ( a K- 6 Australian State School). School is far from a happy place for Matthew - his tearful accounts of his combative relationships with his peers and his teacher highlight his emotional distress. The paper's analytic focus draws attention to some of the ways Matthew's harmful storylines of hegemonic masculinity are made possible through, in particular, his teacher's gendered philosophies and her strategies of individualism and control. In this regard, Matthew's story provides insight into the potentially counterproductive realities of teacher practice in relation to addressing issues of masculinity within the school environment. Against this backdrop, the paper stresses the importance of teachers drawing on a sound research-based framework of gender knowledges that can illuminate how masculinities are constructed, regulated and, indeed, transformed through the power relations of everyday social practice, including teacher practice.

A review of flow modeling for dense medium cyclones

A critical assessment is presented for the existing fluid flow models used for dense medium cyclones (DMCs) and hydrocyclones. As the present discussion indicates, the understanding of dense medium cyclone flow is still far from the complete. However, its similarity to the hydrocyclone provides a basis for improved understanding of fluid flow in DMCs. The complexity of fluid flow in DMCs is basically due to the existence of medium as well as the dominance of turbulent particle size and density effects on separation. Both the theoretical and experimental analysis is done with respect to two-phase motions and solid phase flow in hydrocyclones or DMCs. A detailed discussion is presented on the empirical, semiempirical, and the numerical models based upon both the vorticity-stream function approach and Navier-Stokes equations in their primitive variables and in cylindrical coordinates available in literature. The existing equations describing turbulence and multiphase flows in cyclone are also critically reviewed.
