Social work education from a lesbian standpoint

This study looks at social work education from the standpoint of lesbian students and faculty. The literature indicates that many social workers manifest signs of homophobia, and that this affects the provision of services to gay and lesbian clients. The purpose of this study is to explore how issues of same-gender sexual orientation are addressed in schools of social work and to make recommendations for change. My approach is based on the view that “knowledge” is reflective of the values and experience of those who create it and that education serves to perpetuate and reinforce dominant social values. Looking at institutions from the standpoint of marginalised groups can reveal the ways in which those institutions promote an oppressive ideology. I interviewed fourteen lesbians, including undergraduate and graduate students, recent graduates and faculty members from five Ontario schools of social work. These open-ended interviews focused on the participants\u27 experiences and perspectives on social work education. I also facilitated two reflecting group discussions, each with five of the research participants, which supported and clarified the findings that emerged from the interviews. The findings of this study suggest that social work education is structured by a hidden curriculum which promotes heterosexuality as the only normal and legitimate form of sexual and relational expression. Content on same-gender sexual orientation is excluded from the curriculum and discourse on lesbian and gay issues is suppressed. The lack of a supportive and safe climate in schools of social work limits disclosures of same gender sexual orientation, reinforcing the institutional silence by keeping lesbian and gay experience closeted and invisible. Heterosexual students receive little or no education on same-gender sexual orientation and consequently are unprepared to provide services competently to lesbian and gay clients. The results of this inquiry suggest the need for a multi-faceted approach to change in social work education. CASSW accreditation standards should be changed to require the inclusion of content on issues of same-gender sexual orientation. Schools of social work should adopt policies which prohibit discrimination and harassment based on sexual orientation and statements of philosophy which clearly express opposition to heterosexism and other forms of oppression. Lesbian and gay faculty and students should be actively recruited as part of an effort to increase diversity in schools of social work. Issues of same-gender sexual orientation should be addressed in continuing education for faculty and in faculty evaluation. Feminist theory and critical pedagogy are identified as valuable resources in addressing heterosexism and lesbian and gay issues in social work education

New bryophyte taxon records for tropical countries 1

This is the first in a series of papers listing new records, which will be published whenever sufficient new records have been found. The taxa are arranged by countries for an easier evaluation, e.g. updates of checklists. The initials of the contributor for each record is shown in square brackets after the record, and these initials are interpreted at the end of the paper

Prospects of charged-oscillator quantum-state generation with Rydberg atoms

We explore the possibility of engineering quantum states of a charged mechanical oscillator by coupling it to a stream of atoms in superpositions of high-lying Rydberg states. Our scheme relies on the driving of a two-phonon resonance within the oscillator by coupling it to an atomic two-photon transition. This approach effectuates a controllable open system dynamics on the oscillator that in principle permits versatile dissipative creation of squeezed and other nonclassical states which are central to sensing applications or for studies of fundamental questions concerning the boundary between classical and quantum-mechanical descriptions of macroscopic objects. We show that these features survive thermal coupling of the oscillator with the environment.We perform a detailed feasibility study finding that current state-of-the-art parameters result in atom-oscillator couplings which are too weak to efficiently implement the proposed oscillator state preparation protocol. Finally, we comment on ways to circumvent the present limitations

Single photon production by rephased amplified spontaneous emission

The production of single photons using rephased amplified spontaneous emission is examined. This process produces single photons on demand with high efficiency by detecting the spontaneous emission from an atomic ensemble, then applying a population-inverting pulse to rephase the ensemble and produce a photon echo of the spontaneous emission events. The theoretical limits on the efficiency of the production are determined for several variants of the scheme. For an ensemble of uniform optical density, generating the initial spontaneous emission and its echo using transitions of different strengths is shown to produce single photons at 70% efficiency, limited by reabsorption. Tailoring the spatial and spectral density of the atomic ensemble is then shown to prevent reabsorption of the rephased photon, resulting in emission efficiency near unity
