Turning HIV-Positive Clients into "Responsible Citizens"

In this thesis, I examine an ASO in Pittsburgh, Pennsylvania, in order to explore how case managers interpret the complex needs that HIV-positive clients present while trying to encourage them to become responsible citizens. The data are drawn from participant observation, structured interviews with case managers, and a content analysis of case managers' notes in clients' files. I find that clients do not regularly ask for services related to health maintenance, case managers negotiate surveillance and empowerment strategies in four ways, and external factors complicate case managers' ability to carry out their jobs in a climate of surveillance and empowerment. I conclude that responsible citizenship, in the sense of describing how case managers encourage clients to become more self-sufficient, is present in the language that case managers use to depict their approach to case management with clients

The Visibility of Sexual Minority Movement Organizations in Namibia and South Africa

The South African state has responded favorably to lesbian, gay, bisexual, and transgender (LGBT) social movement organizations' (SMOs) efforts to protect and extend sexual and gender minority rights, whereas Namibian state leaders have verbally attacked LGBT organizing and threatened to arrest sexual and gender minorities. In these countries, LGBT persons have organized themselves into publicly visible social movement organizations (SMOs) over the last ten years. Amid such different official responses to LGBT organizing, how, when, and why do Namibian and South African LGBT social movement organizations become publicly visible or retreat from visibility? To answer this question, I turn to sociologist James M. Jasper's (2004, 2006) concept of "strategic dilemma." LGBT social movement organizations encountered strategic dilemmas of visibility or invisibility when they decide whether and how to become visible, modify their public profile, or forgo political opportunities. To understand the micropolitical dynamics of how LGBT social movement organizations negotiated such strategic dilemmas of visibility and invisibility, I engaged in intensive, continuous ethnographic observation of four Namibian and South African LGBT social movement organizations for approximately 800 hours and analyzed my ethnographic fieldnotes. I also analyzed more than 2,100 newspaper articles and LGBT SMO documents and conducted 56 in-depth interviews with staff, members, and leaders of LGBT SMOs. In this dissertation, I explore the varied strategic dilemmas of visibility and invisibility that Namibian and South African LGBT SMOs faced. My findings advance social movement theorizing by demonstrating the importance of studying social movements in the global South. In addition, my findings contribute to postcolonial feminist and queer theorizing by showing how marginalized sexual and gender minorities in post-apartheid Namibia and South Africa used public visibility as a strategy to argue for their democratic inclusion

The role of serviced offices in the corporate real estate supply chain

The paper analyses the evolving corporate real estate supply chain and the interaction of this evolution with emerging business models in the serviced office sector. An enhanced model of the corporate real estate portfolio is first presented incorporating vacant, alienated and transitory space. It is argued that the serviced office sector has evolved in response to an increasingly diverse corporate real estate portfolio. For the peripheral corporate real estate portfolio, the core serviced workspace product provides the ability to rapidly acquire high-quality workspace and associated support services on very flexible bases. Whilst it is arguably a beta product, the core workspace offer is now being augmented by managed office or back-to-back leases which enables clients to complement the advantages of serviced offices with a wider choice of premises. Joint venture business models are aligned with solutions to problems of vacant space

Evolution and change in the serviced office sector: a decade later

With particular reference to its role in the corporate real estate supply chain, this paper focuses on how the serviced office sector in the UK has evolved and changed over the last decade. A qualitative research approach involving 21 semi-structured interviews with corporate clients of serviced office operators was used to address a number of issues regarding the perceptions of users of serviced offices. It is concluded that the serviced office sector has become an established sector of the UK’s commercial real estate market providing an essential product for many corporate organisations. The serviced office sector has been relatively nimble and a range of operational models have emerged. It was found that corporate organisations use serviced office space and services in order to align workforce change with portfolio change, to transfer risk, for short-term project space, as temporary overflow space, to pilot a new location, to become familiar with a specific geographical marketplace or simply to gain an initial presence in an area

Disability income support design and mental illness: a summary of the grey literature

Aim: Mental illnesses have many distinctive features such as their fluctuating nature, invisibility and lack of diagnostic clarity that make determining eligibility for disability income support challenging. How do policy-makers deal with these features when designing disability income support? More specifically, ‘How do mental illnesses come to be considered eligible disabilities?’, ‘What tools are used to assess mental illness for eligibility?’, ‘What challenges exist in this process?’ and ‘What approaches are used to address these challenges?’ We aimed to determine what evidence is available to policy-makers in Australia and Ontario (Canada) to answer these questions. Methods: Ten electronic databases and grey literature in both jurisdictions were searched using key words including disability income support, disability pension, mental illness, mental disability, addiction, depression and schizophrenia for articles published between 1991 and June 2013 yielding 1,341 articles of which 20 met the inclusion criteria and were critically appraised. Results: Results revealed that there is limited evidence available on disability income support design and mental illness in the Australian and Ontarian setting. Most of the evidence available is from the grey literature and draws on evidence from case law. Many documents reviewed argued that current policy in Australia and Ontario is frequently based on negative assumptions about mental illnesses rather than available evidence (either peer-reviewed or grey literature). Results showed that problems related to mental illness are largely related to the interpretation of the definition rather than the definition itself. Conclusions: The review confirmed that mental illnesses present many challenges when designing disability income support and that academic as well as grey literature, especially case law, provide insight into these challenges. More research is needed on addressing these challenges identified, particularly in these contexts, with the intention that more evidence on this topic could lead to policies for those with mental illness that are well-informed and do not reinforce societal prejudices

Using Gaussian processes to model light curves in the presence of flickering: the eclipsing cataclysmic variable ASASSN-14ag

The majority of cataclysmic variable (CV) stars contain a stochastic noise component in their light curves, commonly referred to as flickering. This can significantly affect the morphology of CV eclipses and increases the difficulty in obtaining accurate system parameters with reliable errors through eclipse modelling. Here we introduce a new approach to eclipse modelling, which models CV flickering with the help of Gaussian processes (GPs). A parametrized eclipse model – with an additional GP component – is simultaneously fitted to eight eclipses of the dwarf nova ASASSN-14ag and system parameters determined. We obtain a mass ratio q = 0.149 ± 0.016 and inclination i = 83$$_{.}^{\circ}$$4 $$^{+0{^{\circ}_{.}} 9}_{-0{^{\circ}_{.}} 6}$$. The white dwarf and donor masses were found to be Mw = 0.63 ± 0.04 M⊙ and Md = 0.093 $$^{+0.015}_{-0.012}$$ M⊙, respectively. A white dwarf temperature Tw = 14 000 $$^{+2200}_{-2000}$$ K and distance d = 146 $$^{+24}_{-20}$$ pc were determined through multicolour photometry. We find GPs to be an effective way of modelling flickering in CV light curves and plan to use this new eclipse modelling approach going forward

Testing the white dwarf mass–radius relationship with eclipsing binaries

We present high-precision, model-independent, mass and radius measurements for 16 white dwarfs in detached eclipsing binaries and combine these with previously published data to test the theoretical white dwarf mass–radius relationship. We reach a mean precision of 2.4 per cent in mass and 2.7 per cent in radius, with our best measurements reaching a precision of 0.3 per cent in mass and 0.5 per cent in radius. We find excellent agreement between the measured and predicted radii across a wide range of masses and temperatures. We also find the radii of all white dwarfs with masses less than 0.48 M¿ to be fully consistent with helium core models, but they are on average 9 per cent larger than those of carbon–oxygen core models. In contrast, white dwarfs with masses larger than 0.52 M¿ all have radii consistent with carbon–oxygen core models. Moreover, we find that all but one of the white dwarfs in our sample have radii consistent with possessing thick surface hydrogen envelopes (10-5 = MH/MWD = 10-4), implying that the surface hydrogen layers of these white dwarfs are not obviously affected by common envelope evolution

Long-term eclipse timing of white dwarf binaries: an observational hint of a magnetic mechanism at work

We present a long-term programme for timing the eclipses of white dwarfs in close binaries to measure apparent and/or real variations in their orbital periods. Our programme includes 67 close binaries, both detached and semi-detached and with M-dwarfs, K-dwarfs, brown dwarfs or white dwarfs secondaries. In total, we have observed more than 650 white dwarf eclipses. We use this sample to search for orbital period variations and aim to identify the underlying cause of these variations. We find that the probability of observing orbital period variations increases significantly with the observational baseline. In particular, all binaries with baselines exceeding 10 yr, with secondaries of spectral type K2 – M5.5, show variations in the eclipse arrival times that in most cases amount to several minutes. In addition, among those with baselines shorter than 10 yr, binaries with late spectral type (>M6), brown dwarf or white dwarf secondaries appear to show no orbital period variations. This is in agreement with the so-called Applegate mechanism, which proposes that magnetic cycles in the secondary stars can drive variability in the binary orbits. We also present new eclipse times of NN Ser, which are still compatible with the previously published circumbinary planetary system model, although only with the addition of a quadratic term to the ephemeris. Finally, we conclude that we are limited by the relatively short observational baseline for many of the binaries in the eclipse timing programme, and therefore cannot yet draw robust conclusions about the cause of orbital period variations in evolved, white dwarf binaries

Gendered Working Environments as a Determinant of Mental Health Inequalities:A Protocol for a Systematic Review

Both gender and employment are critical and intersecting social determinants of mental and physical health. This paper describes the protocol used to conduct a systematic literature review of the relationship between “gendered working environments„ and mental health. Gendered working environments (GWE) are conceptualised as involving: (1) differences in selection into work, and more specifically, occupations; (2) variation in employment arrangements and working hours; (3) disparities in psychosocial exposures at work, and; (4) differences in selection out of work. Methods/design: The review will adhere to a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) search procedure. Key words will be identified that are specific to each of the four domains of GWE. The databases used for the search will be Scopus, Pubmed, Proquest, and Web of Science. Keywords will be adapted for the specific requirements of each electronic database. Inclusion criteria are: Using a validated scale to measure mental health (outcome); including exposures related to the four domains of GWE; reporting estimates for both men and women; and use of a cohort, case-control, or cross-sectional design. Studies will be excluded if they were published more than 10 years ago, are not in English or do not present extractable data on the relationship between GWE and mental health. Discussion: The proposed review will provide evidence about the numerous and complex ways in which employment and gender intersect (and are reinforced) to influence mental health over the life course
