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

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.

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.
