Health beliefs, attitudes, and health-related quality of life in persons with fibromyalgia : mediating role of treatment adherence

Fibromyalgia is a chronic illness characterized by pain and fatigue. Persons with fibromyalgia experience increased the risk for poor mental and physical health-related quality of life, which may be dependent on multiple factors, including health beliefs, such as confidence in physicians and the health-care system, and health behaviors, such as treatment adherence. Respondents with fibromyalgia (n = 409) were recruited nationally, via support organizations, and completed self-report measures: Multidimensional Health Profile – Health Functioning Index (MHP-H), Short-Form-36 Health Survey (SF-36v2), and Medical Outcomes Study (MOS) Measure of Patient Adherence – General Adherence Items. In mediation models, belief in the healthcare system and health-care personnel, and health efficacy exerted an indirect effect through treatment adherence on mental and physical quality of life. Adaptive health beliefs and attitudes were related to greater treatment adherence and, in turn, to a better quality of life. Maladaptive health beliefs and mistrusting attitudes about physician-level and systemic-level healthcare provision are negatively related to both treatment adherence and consequent physical and mental health-related quality of life in persons with fibromyalgia. Future randomized controlled trials are needed to determine if therapeutic strategies to alter health values might improve adherence and self-rated health

Can the effectiveness of an online stress management program be augmented by wearable sensor technology?

Objectives This mixed-methods pilot study sought to examine whether the effectiveness of an online intervention for stress in students could be augmented by the use of prototype wearable sensors. Methods Students who were stressed, but not depressed, were allocated to a stress management program alone (n = 34), with sensors (n = 29), or to no intervention (n = 35). Interventions lasted 4 weeks. Outcome measures included measures of stress, anxious, and depressive symptoms, and were measured immediately after the interventions and 4 weeks later. Participants in the two program groups were interviewed to gain feedback about the program and the sensors. Results Significant pre-post reductions in stress (p = .019) were observed for those in the program alone group. Significant reductions in depressive symptoms were observed among postgraduates (p = .006), but not undergraduates, in the program only group. The program plus sensors group had a broadly similar, but weaker set of results, indicating that the sensors impeded, rather than augmented, the effectiveness of the program. Qualitative data explicate this finding, highlighting participation burden as a key issue. Participants provided detailed feedback about the program, the sensors, and biofeedback exercises, which are summarised and discussed with reference to the quantitative findings. Conclusions The newly developed stress management program could be an effective way to improve student mental health. Wearable sensor technology, particularly biofeedback exercises, may be a useful contribution for the next generation of e-therapies, but further development of the prototypes is needed and their reliability and usability will likely affect user responses to them

Terrestrial habitat requirements of nesting freshwater turtles

Because particular life history traits affect species vulnerability to development pressures, cross-species summaries of life history traits are useful for generating management guidelines. Conservation of aquatic turtles, many members of which are regionally or globally imperiled, requires knowing the extent of upland habitat used for nesting. Therefore, we compiled distances that nests and gravid females had been observed from wetlands. Based on records of \u3e 8000 nests and gravid female records compiled for 31 species in the United States and Canada, the distances that encompass 95% of nests vary dramatically among genera and populations, from just 8 m for Malaclemys to nearly 1400 m for Trachemys. Widths of core areas to encompass varying fractions of nesting populations (based on mean maxima across all genera) were estimated as: 50% coverage = 93 m, 75% = 154 m, 90% = 198 m, 95% = 232 m, 100% = 942 m. Approximately 6–98 m is required to encompass each consecutive 10% segment of a nesting population up to 90% coverage; thereafter, ca. 424 m is required to encompass the remaining 10%. Many genera require modest terrestrial areas (\u3c200 m zones) for 95% nest coverage (Actinemys, Apalone, Chelydra, Chrysemys, Clemmys, Glyptemys, Graptemys, Macrochelys, Malaclemys, Pseudemys, Sternotherus), whereas other genera require larger zones (Deirochelys, Emydoidea, Kinosternon, Trachemys). Our results represent planning targets for conserving sufficient areas of uplands around wetlands to ensure protection of turtle nesting sites, migrating adult female turtles, and dispersing turtle hatchlings

Dynamics of social class contempt in contemporary British television comedy

This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2010 Taylor & Francis.British television comedy has often ridiculed the complexities and characteristics of social class structures and identities. In recent years, poor white socially marginalised groups, now popularly referred to as “chavs”, have become a prevalent comedy target. One of the most popular and controversial television “comedy chavs” is Little Britain's fictional teenage single mother, Vicky Pollard. This article examines the representation of Vicky Pollard in light of contemporary widespread abuse of the white working class. Highlighting the polysemic and ambivalent nature of Vicky Pollard's representation, the article argues that whilst Little Britain's characterisation of Vicky Pollard largely contributes to contemporary widespread demonisation of the working class, there are moments within Little Britain when a more sympathetic tone towards the poor working class may be read, and where chav identities are used to ridicule the pretensions, superficiality, and falsity of middle-class identities. The article concludes that television comedy has been, and continues to be, a significant vehicle through which serious concerns, anxieties, and questions about social class and class identities are discursively constructed and contested

On the mechanisms governing gas penetration into a tokamak plasma during a massive gas injection

A new 1D radial fluid code, IMAGINE, is used to simulate the penetration of gas into a tokamak plasma during a massive gas injection (MGI). The main result is that the gas is in general strongly braked as it reaches the plasma, due to mechanisms related to charge exchange and (to a smaller extent) recombination. As a result, only a fraction of the gas penetrates into the plasma. Also, a shock wave is created in the gas which propagates away from the plasma, braking and compressing the incoming gas. Simulation results are quantitatively consistent, at least in terms of orders of magnitude, with experimental data for a D 2 MGI into a JET Ohmic plasma. Simulations of MGI into the background plasma surrounding a runaway electron beam show that if the background electron density is too high, the gas may not penetrate, suggesting a possible explanation for the recent results of Reux et al in JET (2015 Nucl. Fusion 55 093013)

Velocity-space sensitivity of the time-of-flight neutron spectrometer at JET

The velocity-space sensitivities of fast-ion diagnostics are often described by so-called weight functions. Recently, we formulated weight functions showing the velocity-space sensitivity of the often dominant beam-target part of neutron energy spectra. These weight functions for neutron emission spectrometry (NES) are independent of the particular NES diagnostic. Here we apply these NES weight functions to the time-of-flight spectrometer TOFOR at JET. By taking the instrumental response function of TOFOR into account, we calculate time-of-flight NES weight functions that enable us to directly determine the velocity-space sensitivity of a given part of a measured time-of-flight spectrum from TOFOR

`Football Remembers':The Collective Memory of Football in the Spectacle of British Military Commemoration

This article examines two major rituals of contemporary national life in the UK: association football and military commemoration. It explores the ways in which remembering is enacted and performed within UK football and how these processes are related to issues of power, agency and identity in Britain today. Employing the concepts of collective memory and spectacle, this article argues that ‘memory entrepreneurs’ have sought to embed football as ‘site of memory’ in the performance of military commemoration. It concludes that this has contributed to the transformation of military commemoration, from a ritual that is observed to a spectacle that is consumed. This paper thus contributes to emergent debates on the militarization of civilian space, the shifting nature of civil–military relations in the twenty-first century, and the role of military remembrance in the reproduction of Britishness

Relationship of edge localized mode burst times with divertor flux loop signal phase in JET

A phase relationship is identified between sequential edge localized modes (ELMs) occurrence times in a set of H-mode tokamak plasmas to the voltage measured in full flux azimuthal loops in the divertor region. We focus on plasmas in the Joint European Torus where a steady H-mode is sustained over several seconds, during which ELMs are observed in the Be II emission at the divertor. The ELMs analysed arise from intrinsic ELMing, in that there is no deliberate intent to control the ELMing process by external means. We use ELM timings derived from the Be II signal to perform direct time domain analysis of the full flux loop VLD2 and VLD3 signals, which provide a high cadence global measurement proportional to the voltage induced by changes in poloidal magnetic flux. Specifically, we examine how the time interval between pairs of successive ELMs is linked to the time-evolving phase of the full flux loop signals. Each ELM produces a clear early pulse in the full flux loop signals, whose peak time is used to condition our analysis. The arrival time of the following ELM, relative to this pulse, is found to fall into one of two categories: (i) prompt ELMs, which are directly paced by the initial response seen in the flux loop signals; and (ii) all other ELMs, which occur after the initial response of the full flux loop signals has decayed in amplitude. The times at which ELMs in category (ii) occur, relative to the first ELM of the pair, are clustered at times when the instantaneous phase of the full flux loop signal is close to its value at the time of the first ELM

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
