Of McKay Correspondence, Non-linear Sigma-model and Conformal Field Theory  

CERN Document Server

The ubiquitous ADE classification has induced many proposals of often mysterious correspondences both in mathematics and physics. The mathematics side includes quiver theory and the McKay Correspondence which relates finite group representation theory to Lie algebras as well as crepant resolutions of Gorenstein singularities. On the physics side, we have the graph-theoretic classification of the modular invariants of WZW models, as well as the relation between the string theory nonlinear $\\sigma$-models and Landau-Ginzburg orbifolds. We here propose a unification scheme which naturally incorporates all these correspondences of the ADE type in two complex dimensions. An intricate web of inter-relations is constructed, providing a possible guideline to establish new directions of research or alternate pathways to the standing problems in higher dimensions.

The Fourth Wave of Feminism: Psychoanalytic Perspectives  

British Library Electronic Table of Contents (United Kingdom)

The discussion focuses on the ways in which the 3 panelists in their lives and work embody fourth wave feminism, which combines politics, psychology, and spirituality in an overarching vision of change. Jane Fonda's emphasis on the importance of making narratives of gender a central organizer for personal and societal transformation, Hedda Bolgar's insistence that psychoanalysts recognize the complex dialectic between unconscious dynamics and sociocultural realities in order not to conflate conflicts rooted in social inequalities with individual issues, and Sue Shapiro's understanding of the ambiguous role of individual therapy in situations of historical and social trauma such as the tsunami in Indonesia are all examples of fourth wave feminism in practice. The unfinished business of the ...

Hope versus nursing  

British Library Electronic Table of Contents (United Kingdom)

Hope is an essential dimension of life. Hope, according to Marcel?s thinking, is the act by which the temptation to despair is actively overcome. Hope comes alive when confronting life?s trials, darkness, illness and separation. Marcel differentiates ?I hope? from ?I hope that?. Hope as a central construct for nursing has been analysed, defined, and studied by the nursing theorist Jean Watson in her Theory of Human Caring, and Kaye Herth with her strategies (Herth Hope Index). These strategies are based on Marcel?s existential notion that human beings have an endless possibility of improving their own being.

Collaborative and situated learning on the web ? how can teacher education theoretically and practically respond to changing demands and roles of teachers? : A Research based on case studies of online second language learning in ?communities of practice?  

DEFF Research Database (Denmark)

The background for this paper is a growing interest during the past decade in Denmark in the concepts of ?situated learning?, ?social theory of learning? and ?learning in communities of practice? developed by the American social anthropologist Jean Lave and the Californian Research Scientist Etienne Wenger. The work by Jean Lave from 1988 (Lave, 1988) based on anthropological field studies in Brazil and Liberia as well as later works by Lave & Wenger (Lave and Wenger, 1991; Chaiklin and Lave, 1993; Wenger, 1998; Wenger, McDermott, R. and W. Snyder, 2002) on situated learning and social learning theory have provoked considerable response in anthropological studies, in learning theories as well asin considerations about practical implementation of concepts like ?lifelong learning? in Denmark in recent decades. The European concept of ?lifelong learning? has had a big impact on educational thinking, including teacher education. In addition to this, IT has been playing a continuously ...

Biogeochemistry of the compost bioreactor components of a composite acid mine drainage passive remediation system  

International Nuclear Information System (INIS)

The compost bioreactor ('anaerobic cell') components of three composite passive remediation systems constructed to treat acid mine drainage (AMD) at the former Wheal Jane tin mine, Cornwall, UK were studied over a period of 16 months. While there was some amelioration of the preprocessed AMD in each of the three compost bioreactors, as evidenced by pH increase and decrease in metal concentrations, only one of the cells showed effective removal of the two dominant heavy metals (iron and zinc) present. With two of the compost bioreactors, concentrations of soluble (ferrous) iron draining the cells were significantly greater than those entering the reactors, indicating that there was net mobilisation (by reductive dissolution) of colloidal and/or solid-phase ferric iron compounds within the cells. Soluble sulfide was also detected in waters draining all three compost bioreactors which was rapidly oxidised, in contrast to ferrous iron. Oxidation and hydrolysis of iron, ...
