    Superluminal propagation of an optical pulse in a Doppler broadened three-state, single channel active Raman gain medium

    Get PDF
    Using a single channel active Raman gain medium we show a (220±20)(220\pm 20)ns advance time for an optical pulse of τFWHM=15.4ÎŒ\tau_{FWHM}=15.4 \mus propagating through a 10 cm medium, a lead time that is comparable to what was reported previously. In addition, we have verified experimentally all the features associated with this single channel Raman gain system. Our results show that the reported gain-assisted superluminal propagation should not be attributed to the interference between the two frequencies of the pump field.Comment: 4 pages, 3 figure

    Anomie, Deviant Behavior, and the Olympics

    Get PDF
    Criminal and deviant behavior is known to occur in all places, settings, and times. The Olympics, both Summer and Winter, are not immune to deviant behavior. This paper focuses on the specific types of deviant and criminal acts arising out of the Olympic settings and the anomic factors that possibly lead to deviance in this particular arena. The way that athletes are conformists, innovators, ritualists, and retreatists is considered along with the way that norm confusion influences the Olympic event. Also considered is the role of norm saturation in confusing the way actors interpret appropriate behavior in this setting. Implications are provided

    A sanctuary of tranquillity in a ruptured world: evaluating long-term counselling at a women’s community health centre

    The longitudinal study described in this article evaluated long-term counselling provided at a women’s health centre in the UK for service users on low incomes. The article focuses on the qualitative aspect of the study in which 59 women were interviewed individually before and/or after their counselling. The interviews explored how women make sense of long-term counselling in the context of their gendered experiences and complex needs. The data were analysed using thematic analysis informed by a feminist orientation and attachment theory. Four main themes emerged:‘violence and loss in the context of female oppression’, ‘a sanctuary for women’, ‘non-medicalised long-term counselling in a safe setting’, and ‘benefits of the long view’. Participants attributed various benefits to receiving long-term counselling in a women-only environment. These included gaining employment; reduced suicidal ideation, anxiety and depression; improved physical health, improved confidence and being able to make positive changes in their relationships. The women interviewed post-counselling valued long term-counselling in this context, in contrast to short-term therapy in a medicalised environment. Wider implications with regards to clinical practice and research are discussed

    Evaluation of long-term counselling at a community health service for women who are on a low income

    Aims. Given the lack of research evaluating long-term counselling, coupled with the lack of women-only counselling services, the present study evaluated the long-term counselling service offered by a women-only community health centre. Method. The research ascertained: 1) the characteristics of 155 service users pre-counselling, 2) the views and experiences of 75 service users post-counselling and 3) pre-post-counselling clinical change in 98 service users via the Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM). Results. Unemployment, low income and reports of abuse were related to poorer mental health as measured by the CORE-OM. Content analysis of open-ended questions revealed that women felt supported, comfortable and gained insight through the counselling relationship. They also reported positive changes in their lives, relationships, health behaviours, and psychological wellbeing. Post-counselling improvements were found in CORE-OM scores. Conclusions. Long-term counselling in a women-only environment for socially disempowered women may be beneficial. A research-informed approach to counselling and therapy evaluation, which acknowledges the social context of psychological distress, should be taken across institutions

    Shell-model calculations for the three-nucleon system

    Get PDF
    We use Faddeev's decomposition to solve the shell-model problem for three nucleons. The dependence on harmonic-oscillator excitations allowed in the model space, up to 32ℏΩ32 \hbar\Omega in the present calculations, and on the harmonic-oscillator frequency is studied. Effective interactions derived from Nijmegen II and Reid93 potentials are used in the calculations. The binding energies obtained are close to those calculated by other methods. The structure of the Faddeev equations is discussed and a simple formula for matrix elements of the permutation operators in a harmonic-oscillator basis is given. The Pauli principle is properly treated in the calculations.Comment: 11 pages. REVTEX. 6 PostScript figure

    FP-20-15 Married & Living Apart Together

    Get PDF
    Living apart together (LAT) relationships are an emerging relationship form typically defined as unmarried couples in a committed, long-term relationship who choose to live apart (maintain separate residences) rather than cohabit or marry (Connidis, et al., 2017). Other researchers have classified married couples who live separately as LATs, as well (Binstock & Thornton, 2004). This profile examines the LAT status of newly married individuals who report having entered a marriage in the last year. We define newlywed LATs as those not living with their spouse for reasons other than marital discord1. Using data from IPUMS-USA, we present their characteristics by times married, age, and educational attainment
