GENDERED SPACES OF INDUSTRIAL RESTRUCTURING IN RESOURCE PERIPHERIES: THE CASE OF THE CORNER BROOK REGION, NEWFOUNDLAND
Although industrial restructuring in a resource region might appear at first glance to impact mainly on the predominantly male labour force, in practice it often results in a broader range of economic and social changes as women expand and intensify their entrepreneurial activities as home-based paid workers, and as shifts occur in gender divisions of waged and unwaged labour. The Corner Brook region represents an example of these transformative processes of change. Since restructuring in resource regions occurs in situ, it is necessarily contingent on local place-based geographies and histories, but its impact has profound implications for gender identity and social relations in economically marginalised regions.

Nanomechanics of yeast surfaces revealed by AFM
Despite the large and well-documented characterization of the microbial cell wall in terms of chemical composition, the determination of the mechanical properties of surface molecules in relation to their function remains a key challenge in cell biology.The emergence of powerful tools allowing molecular manipulations has already revolutionized our understanding of the surface properties of fungal cells. At the frontier between nanophysics and molecular biology, atomic force microscopy (AFM), and more specifically single-molecule force spectroscopy (SMFS), has strongly contributed to our current knowledge of the cell wall organization and nanomechanical properties. However, due to the complexity of the technique, measurements on live cells are still at their infancy.In this chapter, we describe the cell wall composition and recapitulate the principles of AFM as well as the main current methodologies used to perform AFM measurements on live cells, including sample immobilization and tip functionalization.The current status of the progress in probing nanomechanics of the yeast surface is illustrated through three recent breakthrough studies. Determination of the cell wall nanostructure and elasticity is presented through two examples: the mechanical response of mannoproteins from brewing yeasts and elasticity measurements on lacking polysaccharide mutant strains. Additionally, an elegant study on force-induced unfolding and clustering of adhesion proteins located at the cell surface is also presented
