Far-field resonance fluorescence from a dipole-interacting laser-driven cold atomic gas

We analyze the temporal response of the fluorescence light that is emitted from a dense gas of cold atoms driven by a laser. When the average interatomic distance is comparable to the wavelength of the photons scattered by the atoms, the system exhibits strong dipolar interactions and collective dissipation. We solve the exact dynamics of small systems with different geometries and show how these collective features are manifest in the scattered light properties such as the photon emission rate, the power spectrum and the second-order correlation function. By calculating these quantities beyond the weak (linear) driving limit, we make progress in understanding the signatures of collective behavior in these many-body systems. Furthermore, we shed light on the role of disorder and averaging on the resonance fluorescence, of direct relevance for recent experimental efforts that aim at the exploration of many-body effects in dipole–dipole interacting gases of atoms

Searching for the greatest Bengali: The BBC and shifting identity categories in South Asia

Drawing on debates generated by the BBC Bengali Language Service's naming of the greatest Bengali of all time, this article investigates the shifting boundaries between group identity categories in our 'globalising' world. First, the controversy over the meaning of the term 'Bengali', which emerged in contemporary Bangladesh and India in response to the BBC's list, is investigated. Then writings and speeches of several of the individuals who were honoured as the greatest Bengalis are analysed in order to draw out the multiple ways they approached their own Bengali identities. In the conclusion, it is argued that rather than imagining the end of place-based identity categories through the process of globalisation, it is more useful to conceptualise shifting categories that continue to incorporate a place-based aspect, but in hybrid and contradictory ways

A closer look at the rhetoric of rape

The entire thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file; a non-technical public abstract appears in the public.pdf file.Title from PDF of title page (University of Missouri--Columbia, viewed on December 29, 2009).Thesis advisor: Dr. Jeff Rice.M.A. University of Missouri--Columbia 2009.Based on the research of Lakoff and Turner, combined with studies in Burkean theory, and the representation of rape, this work presents the problematic use of metaphoric language in US Court rape trials. These are the cause of a growing trend in the public perception of a division between legality and justice in topic of sexual assault. Illustrating this claim is a case study of a rape trial.Includes bibliographical references

Do third-year mental health nursing students feel prepared to assess physical health?

Background The life expectancy for people with mental health issues is significantly lower than the general population, however, their physical health needs are often unrecognised by health professionals. Aim To investigate whether third-year mental health nursing students are clinically prepared to undertake a pre-defined set of physical health checks. Method A 34-item questionnaire was completed by two cohorts of mental health nursing students in their third and final year. Participants self-reported on their competence to assess a range of physical health checks. 37 questionnaires were completed and analysed. Findings Three groups emerged: group 1 – 100% of students self-declared competence in assessments including temperature and pulse, group 2 – more than 50% of students self-declared competence in assessments including urinalysis and pulse oximetry, and group 3 – less than 50% of students self-declared competence in taking electrocardiograms and using the hydration assessment tool. Conclusion The student participants of this study were not adequately prepared to undertake a complete range of physical health assessments for people with mental health issues

Managing diabetes in people with dementia: protocol for a realist review

Background Worldwide, the prevalences of diabetes and dementia are both increasing, particularly in older people. Rates of diabetes in people with dementia are between 13 and 20 %. Diabetes management and diabetic self-care may be adversely affected by the presence of dementia. There is a need to know what interventions work best in the management of diabetes in people living with dementia (PLWD) in different settings and at different stages of the dementia trajectory. The overall aim is to develop an explanatory account or programme theory about ‘what works’ in the management of diabetes in people in what context and to identify promising interventions that merit further evaluation. Methods/design This study uses a realist approach including studies on the management of diabetes in older people, medication management, diabetes-related self-care, workforce issues and assessment and treatment. We will use an iterative, stakeholder driven, four-stage approach. Phase 1: development of initial programme theory/ies through a first scoping of the literature and consultation with key stakeholder groups (user/patient representatives, dementia-care providers, clinicians, diabetes and dementia researchers and diabetes specialists). Phase 2: systematic searches of the evidence to test and develop the theories identified in phase 1. Phase 3: validation of programme theory/ies with a purposive sample of participants from phase 1. Phase 4: actionable recommendations for the management of diabetes in PLWD. Discussion A realist synthesis of the evidence will provide a theoretical framework (i.e. an explanation of how interventions work, for whom, in what context and why) for practice and future research work that articulates the barriers and facilitators to effective management of diabetes in people with dementia. By providing possible explanations for the way in which interventions are thought to work and how change is achieved, it will demonstrate how to tailor an intervention to the setting and patient group. The propositions arising from the review will also inform the design of future intervention studies. Systematic review registration PROSPERO registration number CRD42015020625

Characteristics of mothers with chronically ill children in Jeddah, Saudi Arabia

Children are their parents’ pride and joy. Parents have hopes, dreams and expectations for their children to grow and develop in a holistic healthy manner physically, emotionally, and socially. It is an extremely vulnerable situation when the life and health of children are threatened; hence, when a child is diagnosed with a chronic condition, parents grieve for the loss of their child’s health, their expectations and dreams can be challenged, and their sense of protection, feeling of invulnerability are severely shaken. Objectives: This study focuses on Saudi parents and in particular the mothers who have children with chronic illnesses. It aimed to describe and explore the coping patterns of Saudi mothers who have chronically ill children. Method: A survey questionnaire was administered to 122 Saudi parents with chronically ill children in peadiatric wards at three public hospitals in the Jeddah region in Saudi Arabia. Demographic data, Quality of Life Scale (QOL), The General Self-efficacy scale (GSE) and Social Support Questionnaire (SSQ) were distributed to the Saudi parents with identified chronically ill children. Results: The results of the descriptive statistical analyses provided significant correlations between QOL score and GSE, between QOL and SSQ, between QOL and stress and adversity, between GES and SSQ, between stress and adversity and duration of child’s illness, and between stress and adversity and family time spent in caring activities. In addition, a nearly significant result was found between GES and stress and adversity. Conclusion: The results of the study emphasise the importance of a thorough and holistic assessment of families, their social environments and the level of support they require to assist them to cope with the chronic illness of their children

The supply and movement of Denarii in Roman Britain

Hoards of denarii are common in Britain and the number which have been recorded in detail means that it is now possible to suggest reasonably accurately what a ‘normal’ hoard of a particular date should look like. That being the case, we can then look for variation around that norm and both investigate and speculate what that variation means. A methodology is developed which suggests periods of faster and less rapid coin circulation which has implications for consideration of monetisation. The model also enables us to view where denarii entered circulation; unsurprisingly the army looms large in this picture. The methodology is directly transferable to other provinces and other periods where there are longlived, relatively stable monetary systems

Transabdominal Embryofetoscopy for the Detection of Short Rib-polydactyly Syndrome, Type II(Majewski), in the First Trimester

Our aim was to demonstrate the potential of first-trimester embryofetoscopy for prenatal diagnosis in a continuing pregnancy. A patient at risk for giving birth to an infant with short rib-polydactyly syndrome, type II (Majewski), presented for prenatal diagnosis at 9 weeks of gestation. A 1 mm semirigid fiberoptic endoscope with an 18 gauge examination sheath and a single-chip digital camera were used for transabdominal embryofetoscopy. Transabdominal embryofetoscopy was performed at 13 weeks of gestation. Direct visualization of the fetus was achieved and no gross limb or facial abnormalities were seen. This case shows that embryofetoscopy is a useful tool for early diagnosis in high-risk patients in the first trimester for continuing pregnancies
