Estimates of scale and cost efficiency for Federal Reserve currency operations

Meeting the currency demands of depository institutions, businesses, and consumers costs the Federal Reserve more than half a billion dollars each year, yet, very little research has been devoted to understanding what factors affect such costs. The authors estimate a cost function in order to obtain estimates of scale and cost efficiency for this service. They find that as in other paper-based technologies, such as checks, scale economies are achieved at a relatively low level of output, implying that currency services are not a natural monopoly. They also provide estimates of facility-specific marginal costs and returns to scale measures that could be used to improve resource allocations. Lastly, they find that the average processing facility operates at more 80 percent of the efficiency of the “best practice” facility, comparable to cost efficiency estimates that have been reported elsewhere for private-sector financial institutions.Federal Reserve banks - Costs ; Payment systems

To make PhDs fit for the 21st century we need to develop evidence based policies

The growth of PhD level education globally and in the UK has changed the nature of what it means to be a PhD holder. However, despite there being more PhDs and more value placed on producing them, there is still a severely limited evidence base for understanding PhD outcomes. Drawing on their recent working paper, Sally Hancock and Paul Wakeling outline key policy issues around PhD education and put forward an agenda for developing an evidence base for making PhDs fit for the 21st century

The use of admissions simulation to stabilize ancillary workloads

As part of the planning of a new hospital, an analysis was per formed to determine the number of procedures that would be performed in each of nineteen ancillary departments on a day of the week basis. Because the planned occupancy was not the maximum possible, attempts were made using simulation to smooth the daily ancillary loads by varying the admission day of elective, urgent inpatient and outpatient loads. The methodology, sample outputs, and main conclusions are presented.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69095/2/10.1177_003754978404300203.pd

Does personal experience of dementia change attitudes? The Bristol and South Gloucestershire survey of dementia attitudes

Background: it is unclear how attitudes towards people with dementia are formed and whether, for instance, increased contact with people with dementia, either through work or personal experience alters attitudes. This study used a validated questionnaire (the Approaches to Dementia Questionnaire or ADQ) to examine whether having experience of dementia (either as a result of work, or by being affected by dementia) is associated with differences in attitudes towards dementia.Methods: a modified version of the ADQ was completed by 2,201 participants, either on-line or in written form. Participants also recorded their age, gender and ethnicity as well as whether they worked with people with dementia, or had been personally affected by dementia.Results: increased contact with people with dementia was associated with increases in both total ADQ scores and across both sub-scales reflecting more positive person-centred attitudes toward dementia. The highest levels of increase were found amongst non-white participants.Conclusions: this study is, we believe, the first attempt to look systematically at whether greater contact with people with dementia is associated with changes in attitudes. The results strongly support the contention that increased contact with people with dementia leads to more person-centred attitudes, and by inference, less stigmatising views

The enigma of facial asymmetry:is there a gender specific pattern of facedness?

Although facial symmetry correlates with facial attractiveness, human faces are often far from symmetrical with one side frequently being larger than the other (Kowner, 1998). Smith (2000) reported that male and female faces were asymmetrical in opposite directions, with males having a larger area on the left side compared to the right side, and females having a larger right side compared to the left side. The present study attempted to replicate and extend this finding. Two databases of facial images from Stirling and St Andrews Universities, consisting of 180 and 122 faces respectively, and a third set of 62 faces collected at Abertay University, were used to examine Smith's findings. Smith's unique method of calculating the size of each hemiface was applied to each set. For the Stirling and St Andrews sets a computer program did this automatically and for the Abertay set it was done manually. No significant overall effect of gender on facial area asymmetry was found. However, the St Andrews sample demonstrated a similar effect to that found by Smith, with females having a significantly larger mean area of right hemiface and males having a larger left hemiface. In addition, for the Abertay faces handedness had a significant effect on facial asymmetry with right-handers having a larger left side of the face. These findings give limited support for Smith's results but also suggest that finding such an asymmetry may depend on some as yet unidentified factors inherent in some methods of image collection

Workplace interventions to improve sitting posture: a systematic review.

Evaluate the effectiveness of workplace interventions to improve sitting posture of workers that spend long periods of time seated at a visual display terminal. A systematic review of randomised controlled trials, non-randomised controlled trials and single-group intervention trials featuring workplace interventions with pre- and follow-up measurements of sitting posture was conducted (registered in PROSPERO, CRD#42015027648). Nine databases were searched for studies available between January 2005 and February 2016. 2519 articles were screened with 12 studies meeting the inclusion criteria. The included studies featured various ergonomic workplace interventions and comprised 4 randomised controlled trial (n = 457), 2 non-randomised controlled trials (n = 416) and 6 single-group intervention trials (n = 328). Due to clinical and methodological heterogeneity, pooling of data was not completed and a narrative summary of findings was developed using the Grading of Recommendations Assessment Development and Evaluation (GRADE) framework. The evidence for four review outcomes was assessed with medium to large positive improvements obtained for the majority of studies investigating changes to gross sitting posture, whereas mixed findings were obtained for more specific local segment assessments of sitting posture. The overall evidence quality for all review outcomes were identified as either 'low' or 'very low'. There is evidence which is limited in quality to indicate that ergonomic workplace interventions can improve gross sitting posture. More high quality research across a range of intervention types is required with longer follow-up durations and more advanced methods to assess sitting posture with greater frequency and less bias
