Assistant grade nurses and nursing students : a diary study

Background Little is known about the role of the assistant grade nurse in the clinical development of pre-registration nursing students during their practice placements; even less is known about this relationship in the mental health field. Aim To explore the relationship between assistant grade nurses and mental health nursing students. Methods Using a phenomenological approach, diaries of nine participants – three nursing students, three assistant grade nurses and three mentors – helped to inform semi-structured interviews. The data were analysed using interpretative phenomenological analysis. Findings Students recognised that a substantial percentage of their practice was supervised by assistant grade nurses. There was also a clear connection between assistant grade nurse supervision and the delivery of direct care. Conclusion This study has confirmed the existence of a more extensive educational relationship between assistant grade nurses and mental health nursing students than had previously been recognised

Local Approximations for Effective Scalar Field Equations of Motion

Fluctuation and dissipation dynamics is examined at all temperature ranges for the general case of a background time evolving scalar field coupled to heavy intermediate quantum fields which in turn are coupled to light quantum fields. The evolution of the background field induces particle production from the light fields through the action of the intermediate catalyzing heavy fields. Such field configurations are generically present in most particle physics models, including Grand Unified and Supersymmetry theories, with application of this mechanism possible in inflation, heavy ion collision and phase transition dynamics. The effective evolution equation for the background field is obtained and a fluctuation-dissipation theorem is derived for this system. The effective evolution in general is nonlocal in time. Appropriate conditions are found for when these time nonlocal effects can be approximated by local terms. Here careful distinction is made between a local expansion and the special case of a derivative expansion to all orders, which requires analytic behavior of the evolution equation in Fourier space.Comment: 14 pages, 2 figures.

Tackling Bullying in Scotland's Schools : a View from the Sidelines

This policy brief considers the proposals to reduce bullying in Scotland's schools. A number of interventions have been introduced in Scotland’s schools that that place an emphasis on peer-initiated interventions. However these interventions often fail to consider the mental health and wellbeing of the pupils involved. The role of the so-called pupil 'bystander' is fundamentally misunderstood as these pupils often have multiple roles within ‘school yard’ culture. The lack of independently evaluated evidence on the success of direct pupil-initiated interventions to reduce the level of bullying in schools should be of concern to policymakers. A key recommendation is that schools, education authorities and policymakers pause, review the evidence and have an informed discussion about the most effective interventions to deliver safer schools in Scotland

Measuring workplace bullying

Workplace bullying is increasingly being recognized as a serious problem in society today; it is also a problem that can be difficult to define and evaluate accurately. Research in this area has been hampered by lack of appropriate measurement techniques. Social scientists can play a key part in tackling the phenomenon of workplace bullying by developing and applying a range of research methods to capture its nature and incidence in a range of contexts. We review current methods of research into the phenomenon of bullying in the workplace. We examine definitional issues, including the type, frequency, and duration of bullying acts, and consider the role of values and norms of the workplace culture in influencing perception and measurement of bullying behavior. We distinguish methods that focus on: (a) inside perspectives on the experience of bullying (including questionnaires and surveys, self-report through diary-keeping, personal accounts through interviews, focus groups and critical incident technique, and projective techniques such as bubble dialogue); (b) outside perspectives (including observational methods and peer nominations); (c) multi-method approaches that integrate both inside and outside perspectives (including case studies). We suggest that multi-method approaches may offer a useful way forward for researchers and for practitioners anxious to assess and tackle the problem of bullying in their organizations.CIFPEC/CIEC - Centro de Investigação em Estudos da Criança, UM (UI 644 e 317 da FCT)

Connection between the Accretion Disk and Jet in the Radio Galaxy 3C 111

We present the results of extensive multi-frequency monitoring of the radio galaxy 3C 111 between 2004 and 2010 at X-ray (2.4--10 keV), optical (R band), and radio (14.5, 37, and 230 GHz) wave bands, as well as multi-epoch imaging with the Very Long Baseline Array (VLBA) at 43 GHz. Over the six years of observation, significant dips in the X-ray light curve are followed by ejections of bright superluminal knots in the VLBA images. This shows a clear connection between the radiative state near the black hole, where the X-rays are produced, and events in the jet. The X-ray continuum flux and Fe line intensity are strongly correlated, with a time lag shorter than 90 days and consistent with zero. This implies that the Fe line is generated within 90 light-days of the source of the X-ray continuum. The power spectral density function of X-ray variations contains a break, with steeper slope at shorter timescales. The break timescale of 13 (+12,-6) days is commensurate with scaling according to the mass of the central black hole based on observations of Seyfert galaxies and black hole X-ray binaries (BHXRBs). The data are consistent with the standard paradigm, in which the X-rays are predominantly produced by inverse Compton scattering of thermal optical/UV seed photons from the accretion disk by a distribution of hot electrons --- the corona --- situated near the disk. Most of the optical emission is generated in the accretion disk due to reprocessing of the X-ray emission. The relationships that we have uncovered between the accretion disk and the jet in 3C 111, as well as in the FR I radio galaxy 3C 120 in a previous paper, support the paradigm that active galactic nuclei and Galactic BHXRBs are fundamentally similar, with characteristic time and size scales proportional to the mass of the central black holeComment: Accepted for publication in ApJ. 18 pages, 17 figures, 11 tables (full machine readable data-tables online in ApJ website
