Dismantling the signposts to public health? NHS data under the Health and Social Care Act 2012

The Health and Social Care Act 2012 will replace the administrative structure of the NHS in England, currently based on the resident populations of defined geographical areas, with one that relates instead to the shifting populations of individuals registered with specific general practices at given points in time.1 This will radically change the longstanding basis for collecting data routinely about the health needs of local populations, making it difficult to monitor the effect of new legislation on the health of the population locally or nationally.2 3 We discuss some of the implications of the act for existing routine data systems and the production of routine statistics that underpin essential NHS functions, including monitoring healthcare provision and ensuring equity of access, allocation of resources, and measurement of outcomes

Permutation sampling in Path Integral Monte Carlo

A simple algorithm is described to sample permutations of identical particles in Path Integral Monte Carlo (PIMC) simulations of continuum many-body systems. The sampling strategy illustrated here is fairly general, and can be easily incorporated in any PIMC implementation based on the staging algorithm. Although it is similar in spirit to an existing prescription, it differs from it in some key aspects. It allows one to sample permutations efficiently, even if long paths (e.g., hundreds, or thousands of slices) are needed. We illustrate its effectiveness by presenting results of a PIMC calculation of thermodynamic properties of superfluid Helium-four, in which a very simple approximation for the high-temperature density matrix was utilized

Fatigue damage growth mechanisms in continuous fiber reinforced titanium matrix composites

The role of fiber/matrix interface strength, residual thermal stresses, and fiber and matrix properties on fatigue damage accumulation in continuous fiber metal matrix composites (MMC) is discussed. Results from titanium matrix silicon carbide fiber composites is the primary topic of discussion. Results were obtained from both notched and unnotched specimens at room and elevated temperatures. The stress in the 0 deg fibers was identified as the controlling factor in fatigue life. Fatigue of the notched specimens indicated that cracks can grow in the matrix materials without breaking fibers

Longitudinal study of local authority child and family social workers (wave 1) Findings from a 5 year study of local authority child and family social workers in England.

The longitudinal study investigates recruitment, retention and career progression in local authority child and family social work over 5 years. This is the first of 5 reports. It provides workforce information for employers and policy makers. Topics covered in this report include: •entry routes into local authority child and family social work •current employment and career history •workplace wellbeing •management, supervision and working environment •job satisfaction •career progression and future career plan

Development of quantum perspectives in modern physics

Introductory undergraduate courses in classical physics stress a perspective that can be characterized as realist; from this perspective, all physical properties of a classical system can be simultaneously specified and thus determined at all future times. Such a perspective can be problematic for introductory quantum physics students, who must develop new perspectives in order to properly interpret what it means to have knowledge of quantum systems. We document this evolution in student thinking in part through pre- and post-instruction evaluations using the Colorado Learning Attitudes about Science Survey. We further characterize variations in student epistemic and ontological commitments by examining responses to two essay questions, coupled with responses to supplemental quantum attitude statements. We find that, after instruction in modern physics, many students are still exhibiting a realist perspective in contexts where a quantum-mechanical perspective is needed. We further find that this effect can be significantly influenced by instruction, where we observe variations for courses with differing learning goals. We also note that students generally do not employ either a realist or a quantum perspective in a consistent manner.Comment: 18 pages, plus references; 3 figures; 9 tables. PACS: 01.40.Fk, 03.65._

Estimating the abundance of inshore dolphins in the Kimberley, north-western Australia

Assessing the abundance of wildlife populations is essential to their effective conservation and management. Concerns have been raised over the vulnerability of tropical inshore dolphins in waters off northern Australia to anthropogenic impacts on local populations, yet a lack of abundance data precludes assessment of their conservation status and the management of threats

Arts and creative activities for mental wellbeing during Covid-19 lockdown: report of a survey of university staff

Purpose There is evidence that the recent Covid-19 pandemic has led to an increase in stress in the UK workforce. Research also suggests that engaging in arts and creative activities may alleviate stress. The purpose was to explore how this might relate to staff at Canterbury Christ Church University, and specifically 1) to identify the overall extent of uptake and popularity of different arts activities; 2) to assess how this compares with pre-Covid levels of engagement and; 3) to identify how engagement with activities may serve to mitigate any adverse effects of the pandemic and beyond. Design The two-stage design comprised an online questionnaire, followed by in-depth interviews with a sub-sample of respondents. Findings 178 individuals responded to the questionnaire, and 12 individuals were interviewed. Receptive arts engagement featured more frequently than participatory arts. 46.6% respondents reported more engagement during lockdown than before. The most frequently reported benefits related to the ability to disengage from the negative concerns of lockdown. Interview data identified four themes: creativity for wellbeing; connecting and contributing; pandemic as opportunity; and reflecting the times. Originality Little previous research has been conducted on the impacts of the arts specifically on university staff during Covid, particularly research including non-academic staff
