Gender And Culture In Psychology: Theories And Practices

Gender and Culture in Psychology introduces new approaches to the psychological study of gender that bring together feminist psychology, socio-cultural psychology, discursive psychology and critical psychology. It presents research and theory that embed human action in social, cultural and interpersonal contexts. The book provides conceptual tools for thinking about gender, social categorization, human meaning-making, and culture. It also describes a family of interpretative research methods that focus on rich talk and everyday life. It provides a close-in view of how interpretative research proceeds. The latter part of the book showcases innovative projects that investigate topics of concern to feminist scholars and activists: young teens\u27 encounters with heterosexual norms; women and men negotiating household duties and childcare; sexual coercion and violence in heterosexual encounters; the cultural politics of women\u27s weight and eating concerns; psychiatric labeling of psychological suffering; and feminism in psychotherapy

Doing Interview-Based Qualitative Research: A Learner\u27s Guide

For many students, the experience of learning about and using qualitative methods can be bewildering. This book is an accessible step-by-step guide to conducting interview-based qualitative research projects. The authors discuss the \u27hows\u27 and \u27whys\u27 of qualitative research, showing readers the practices as well as the principles behind them. The book first describes how to formulate research questions suited to qualitative inquiry. It then discusses in detail how to select and invite research participants into a study and how to design and carry out good interviews. It next presents several ways to analyze interviews and provides readers with many worked examples of analyses. It also discusses how to synthesize findings and how to present them. Doing Interview-based Qualitative Research equips readers in disciplines such as psychology, sociology, education, counseling, nursing, and public health with the knowledge and skills necessary to embark on their own projects. People continually reflect on themselves and their worlds, and they are continually called upon to give accounts of themselves. People have hopes, fears, reasons, intentions, and values, and they may experience times of satisfaction, confusion, and demoralization. The premise of this book is that researchers ought to and can study these matters. In this book, we give readers the conceptual framework and practical tools to do so

The impact of information and communication technology on family carers of older people and professionals in Sweden

Government policy in Sweden, as in other developed countries, pays increasing attention as to how best to support the family carers of older people. New and innovative means of support, such as information and communication technology, are emerging. This paper explores the perceived benefits of, and barriers to, information technology as a means of supporting family carers of older people. Following a brief overview of the care-giving literature, with particular reference to the Swedish context, interview and questionnaire data collected from 34 families who took part in the Swedish ACTION project are used to explore the role of user-friendly information and communication technology to inform and enable family carers of older people to exercise choice, to care more effectively and to work in partnership with professionals. Interview data from two groups of professionals that utilised ACTION are also examined to throw light on its potential benefits for both carers and professionals. Consideration is given to the barriers to using information technology, and to identifying those carers most likely to benefit. Areas for further development are the need for practitioners' education and a wider range of programmes to address carers' diverse needs. Clearly, lessons learned from the Swedish project have wider relevance, given that new forms of support are being developed in most technically advanced countries

Functional renormalization group approach to the singlet-triplet transition in quantum dots

We present a functional renormalization group approach to the zero bias transport properties of a quantum dot with two different orbitals and in presence of Hund's coupling. Tuning the energy separation of the orbital states, the quantum dot can be driven through a singlet-triplet transition. Our approach, based on the approach by Karrasch {\em et al} which we apply to spin-dependent interactions, recovers the key characteristics of the quantum dot transport properties with very little numerical effort. We present results on the conductance in the vicinity of the transition and compare our results both with previous numerical renormalization group results and with predictions of the perturbative renormalization group.Comment: 15 pages, 9 figure

Spin-orbit coupled cold exciton condensates

We analyze theoretically the dynamics of degenerate condensate of cold indirect excitons. We account for both linear spin dependent terms arising from spin-orbit interaction of Rashba and Dresselhaus types and non-linear terms transforming a pair of bright excitons into a pair of dark ones. We show that both terms should lead to the qualitative changes in the dynamics of cold exciton droplets in the real space and time.Comment: 14 pages, 7 figure

Density-matrix approach for an interacting polariton system

Using the Lindblad approach we develop a general formalism for theoretical description of a spatially inhomogeneous bosonic system with dissipation provided by the interaction of bosons with a phonon bath. We apply our results to model the dynamics of an interacting one-dimensional polariton system in real space and time, analyzing in detail the role of polariton-polariton and polariton-phonon interactions.Comment: 7 pages + 3 figures. arXiv admin note: text overlap with arXiv:1103.1336 by other author

Bistability phenomena in one-dimensional polariton wires

We investigate the phenomena of bistability and domain wall propagation in polaritonic systems with dissipation provided by the interaction with incoherent phonon bath. The results on the temperature dependence of the polariton bistability behavior and polariton neuron switching are presented.Comment: 6 pages + 4 figures. Continuation of the work published in Phys. Rev. B 83, 165316 (2011

Phonon-mediated Josephson oscillations in excitonic and polaritonic condensates

We analyze theoretically the role of the exciton-phonon interactions in phenomena related to the Josephson effect between two spatially separated exciton and exciton-polariton condensates. We consider the role of the dephasing introduced by phonons in such phenomena as Josephson tunneling, self-trapping and spontaneous polarization separation. In the regime of cw pumping we find a remarkable bistability effect arising from exciton- exciton interactions as well as regimes of self- sustained regular and chaotic oscillations.Comment: 10 pages, Submitted to Phys. Rev.
