Multiplatform Public Service Broadcasting: The Economic and Cultural Role of UK Digital and TV Independents

In this report, produced as part of a two-year Arts & Humanities Research Council project (AH-H0185622-2) on ‘multiplatform public service broadcasting’, focusing on factual/specialist factual as a case study, we detail the role independent production companies play in PSB. We set out how PSB informs the production cultures of independent companies, the tensions that are experienced between profit and public service and the impact multiplatform commissioning and production practices have had on the sector

The Development and Psychometric Testing of the Nurse Practitioner Role Transition Scale

Nurse practitioners (NPs) are formidable members of the health care system providing high quality, cost-effective care. Their transition into practice is often fraught with unexpected challenges. In support of this dissertation, a series of three studies was conducted to improve the process of NP role transition by increasing our knowledge and understanding of the defining constructs and the development and validation of the NP role transition scale (NPRTS). The NPRTS is a self-report survey designed to measure NP’s perceptions of role transition experiences during the first year of practice. Two individual studies supported the development and evolution of the NPRTS through factor analyses and reliability assessments. In a third study, a qualitative analysis including a subset of neonatal NPs was conducted to further our understanding of role transition constructs and support the revisions of the NPRTS. Two samples comprised of 182 and 427 NPs representing a variety of specialties and practice settings participated in the scale development studies. Multiple factor analyses provided empirical support for the existence of the resulting three factor eighteen indicator model. Internal consistency for the final three factors was high. A qualitative analysis of 70 neonatal NPs revealed four themes that described the reattainment of expert status during role transition: 1) First impressions: Am I prepared? 2) The transition, 3) Making it as a real NNP, and 4) The helpers and hinderers. The resulting NPRTS model is inferred as a valid and reliable measure of the constructs of NP role transition including: 1) confidence, comfort, and competence in the role; 2) collegial relationships; and 3) understanding of the role by clients. Implications for practice include the implementation of the NPRTS as a beginning model for NP role transition discussions and as a means to assess transition progress in the clinical setting. Continued research is warranted to progress the understanding of NP role transition and for the refinement and validation of the NPRTS

“YOU CAN STAY IF YOU WANT” -- WOMEN’S EXPERIENCES PROVIDING RAPE CRISIS MEDICAL ADVOCACY

Many survivors of sexual trauma describe the forensic rape exam as a second rape (Campbell et al., 1999; Parrot, 1991). Rape crisis medical advocates (RCMAs) assist survivors through this process, a time of particular vulnerability to retraumatization (Resnick, Acierno, Holmes, Kilpatrick, & Jager, 1999), by providing emotional support, education, and advocacy for comprehensive and respectful services. Campbell (2006) stated that the primary role of the RCMA is to reduce victim-blame, or the tendency to blame the victim of a crime for the crime or the circumstances leading up to it. The literature has consistently shown that survivors who worked with RCMAs received more medical and legal services and were less likely to feel revictimized (Campbell, 2006; Resnick et al., 1999; Wasco et al., 2004), but the impact of the work on RCMAs has not been sufficiently examined. Previous research has shown that many advocates experienced anger and fear in relation to the work (Wasco & Campbell, 2002), that RCMAs who witnessed more victim-blame reported less satisfaction with the work and lower levels of affective commitment to the job (Hellman & House, 2006), and that professional counselors who worked with trauma survivors reported higher levels of vicarious trauma than those who did not (Schauben & Frazier, 1995). Other researchers have shown that counselors who worked with trauma survivors reported higher traumatic stress than those who did not, and counselors who worked with victims of sexual trauma endorsed more disruptive beliefs about self, others, and the world (Bober & Regehr, 2005). However, the appropriateness of generalizing results observed among counselors to RCMAs is unclear. The purpose of this study was to examine possible predictors of RCMAs’ experiences of vicarious trauma (VT) and vicarious post-traumatic growth (VPTG). Since a great deal of research examining the effects of trauma on care-providers focuses on individual-level contributing variables like personality style, coping skills, and history of victimization (Kelley, Schwerin, Farrar, & Lane, 2005; King, King, Fairbank, & Adams, 1998; Pearlman & Mac Ian, 1995), in this study I examined the predictive ability of several environmental/contextual/systemic variables on RCMAs ratings of VT and VPTG, including caseload, amount of formal individual and group supervision received, ratings of social community at work, meaning of the work, emotional demands of the work, and perceptions of witnessing VB by police and medical staff. One hundred and sixty-four RCMAs participated in this internet-based survey research. A series of hierarchical regression analyses demonstrated that higher ratings of VT were predicted by younger age, lower amounts of formal group supervision received, and lower ratings of the social community at work and the meaning of the work. Ratings of VPTG were significantly and positively predicted by amount of formal individual supervision received, and negatively predicted by age and educational achievement. Interpretations and recommendations are provided to assist rape crisis agencies in supporting RCMAs in their work

Influence of biomaterial nanotopography on the adhesive and elastic properties of Staphylococcus aureus cells

Despite the well-known beneficial effects of biomaterial nanopatterning on host tissue integration, the influence of controlled nanoscale topography on bacterial colonisation and infection remains unknown. Therefore, the aim of the present study was to determine the nanoscale effect of surface nanopatterning on biomaterial colonisation by S. aureus, utilising AFM nanomechanics and single-cell force spectroscopy (SCFS). Nanoindentation of S. aureus bound to planar (PL) and nanopatterned (SQ) polycarbonate (PC) surfaces suggested two distinct areas of mechanical properties, consistent with a central bacterial cell surrounded by a capsullar component. Nevertheless, no differences in elastic moduli were found between bacteria bound to PL and SQ, suggesting a minor role of nanopatterning in bacterial cell elasticity. Furthermore, SCFS demonstrated increased adhesion forces and work between S. aureus and SQ surfaces at 0 s and 1 s contact times. Although WLC modelling showed similarities in contour lengths for attachment to both surfaces, Poisson analysis suggests increased short-range forces for the S. aureus–SQ interactions. In the case of S. aureus–PL, long-range forces were found to not only be dominant but also repulsive in nature, which may help explain the reduced adhesion forces observed during AFM probing. In conclusion, although surface nanopatterning does not significantly influence the elasticity of attached bacterial cells, it was found to promote the early-adhesion of S. aureus cells to the biomaterial surface

Observation of magnetic circular dichroism in Fe L_{2,3} x-ray-fluorescence spectra

We report experiments demonstrating circular dichroism in the x-ray-fluorescence spectra of magnetic systems, as predicted by a recent theory. The data, on the L_{2,3} edges of ferromagnetic iron, are compared with fully relativistic local spin density functional calculations, and the relationship between the dichroic spectra and the spin-resolved local density of occupied states is discussed

How should we treat vascular and fibrotic lung disease in scleroderma?

Recent randomized trials suggest that evidence-based algorithms for systemic sclerosis can be developed to identify patients at risk for lung disease, follow lung disease progression, and modify disease with therapies of proven benefit. Recognition of disease subsets allows physicians to integrate physiology, overlapping disease manifestations, and predictable drug effects into a comprehensive disease management program
