New Releases by David Kirk

Can we imagine a future in which physical education in schools no longer exists? In this controversial and powerful meditation on physical education, David Kirk argues that a number of different futures are possible. Kirk argues that multi-activity, sport-based forms of physical education have been dominant in schools since the mid-twentieth century and that they have been highly resistant to change. The practice of physical education has focused on the transmission of de-contextualised sport-techniques to large classes of children who possess a range of interests and abilities, where learning rarely moves beyond introductory levels. Meanwhile, the academicization of physical education teacher education since the 1970s has left teachers less well prepared to teach this programme than they were previously, suggesting that the futures of school physical education and physical education teacher education are intertwined. Kirk explores three future scenarios for physical education, arguing that the most likely short-term future is ‘more of the same’. He makes an impassioned call for radical reform in the longer-term, arguing that without it physical education faces extinction. No other book makes such bold use of history to interrogate the present and future configurations of the discipline, nor offers such a wide-ranging critique of physical culture and school physical education. This book is essential reading for all serious students and scholars of physical education and the history and theory of education.

Shimmer volunteers to put her siblings to bed and discovers the job is not without its complications.

Cilia are multifunctional organelles implicated in many human diseases. Cilia project from the cell surface and thus are well-situated for roles both in motility and sensory reception. The green alga Chlamydomonas reinhardtii is a useful model system for studies of cilia due to its combination of genetics, molecular biology, and biochemistry. At the base of cilia are modified centrioles called basal bodies, which are connected with cilia via a transition zone. Ciliary assembly and disassembly must be co-ordinated with cell cycle progression because the basal bodies must be freed in order to organize the mitotic spindle. Ciliary disassembly can occur either by deflagellation, a drastic stress response, or resorption, a gradual process normally occurring before cell division. I hypothesized that there might be commonality between the two pathways for ciliary loss. I discovered that cells with mutations in ciliary assembly invoke deflagellation in some circumstances, and resorption in others. Deflagellation mutants also exhibited resorption defects, supporting my hypothesis. To further explore the relationship between deflagellation and cell cycle, Qasim Rasi and I examined katanin, a microtubule-severing protein implicated in deflagellation in Chlamydomonas, and in mitosis in mammalian cells. A reverse genetics approach revealed that the only cells that can survive knock-down of katanin are mutants which already lack cilia. This led us to form the hypothesis that the role of katanin in the cell cycle is related to its cilia-severing activity. In support of this idea, I observed that wild-type cells entering mitosis sever their cilia to free the basal bodies. Katanin-mediated deflagellation is defective in fa2 mutants, and FA2 is a member of the Nek family of mitotic kinases. The Neks are a large family of kinases and through evolutionary analyses, Brian Bradley and I discovered that the family expanded early in eukaryotic evolution and it is likely that Neks co-ordinate the cycle of ciliary assembly and dissasemby with cell cycle progression. This study also identified the Chlamydomonas Nek CNK3 as an orthologue of the human disease gene Nek8, suggesting an avenue to further disease-related research.
