Prising open the black box: Critical realism, action research and social work

There is a growing interest in critical realism and its application to social work. This article makes a case for adopting this philosophical position in qualitative social work research. More specifically, it suggests that there is a concordance between critical realist premises and action research with its cyclical inquiry and advancement of social change. This combination of philosophy and method, it is argued, promotes anti-oppressive social work research and illuminates the processes shaping outcomes in programme evaluations. Overall, the article underscores the importance of 'depth' in qualitative inquiry by conceiving the social world in terms of five interlacing, social domains.

"That a black twisty divil could be hiding under such comeliness": Woman vs woman in Early Twentieth-Century Irish Theatre

This essay investigates representations of womanhood in early twentieth-century Irish theatre, particularly in terms of the disjunction between woman as a physical, social being and the symbolic Woman as an ideological construction promoted by both church and state. It uses Lacanian theory in conjunction with Irish women’s studies scholarship to inform the analyses of plays by dramatists including Maud Gonne, Padraic Colum, Lennox Robinson, and T. C. Murray. The aim is to show how women in Irish society were faced with the impossible task of fulfilling such idealized roles as Woman, Wife, and Mother, and how this situation was variously represented and contested in the theatre during the first quarter of the twentieth century.

Nonlinear compressional electromagnetic ion-cyclotron wavepackets in space plasmas

The parametric coupling between large amplitude magnetic field-aligned circularly polarized electromagnetic ion-cyclotron (EMIC) waves and ponderomotively driven ion-acoustic perturbations in magnetized space plasmas is considered. A cubic nonlinear Schrodinger equation for the modulated EMIC wave envelope is derived, and then solved analytically. The modulated EMIC waves are found to be stable (unstable) against ion-acoustic density perturbations, in the subsonic (supersonic, respectively) case, and they may propagate as "supersonic bright" ("subsonic dark", i.e. "black" or "grey") type envelope solitons, i.e. electric field pulses (holes, voids), associated with (co-propagating) density humps. Explicit bright and dark (black/grey) envelope excitation profiles are presented, and the relevance of our investigation to space plasmas is discussed.
