Graduate Employment in the UK: An Application of the Gottschalk-Hansen Model

There is an apparent inconsistency in the existing literature on graduate employment in the UK. While analyses of rates of return to graduates or graduate markups show high returns, suggesting that demand has kept up with a rapidly rising supply of graduates, the literature on over-education suggests that many graduates are unable to find employment in graduate jobs and the proportion over-educated has risen over time. Using a simple supply and demand model applied to UK data that defines graduate jobs in terms of the proportion of graduates and/or the graduate earnings markup within occupations, we find that the employment of graduates in non-graduate jobs has declined over time. Hence, there is no evidence of an over-production of graduates in the UK.employment, wages, education, graduates

How analysts process information: technical and financial disclosures in the microprocessor industry

Following Bradshaw (‘Analyst information processing, financial regulation, and academic research’ [2009], and Analysts' forecasts: What do we know after decades of work? [2011]), this paper examines how analysts process information, particularly in an information environment characterised by multiple and potentially complementary information sources. The setting is the microprocessor industry, one in which technical information is particularly significant and complex to digest. Based on 3837 analyst earnings-forecast revisions, issued by 134 analysts, we examine quantitatively the speed, magnitude, and information content of the reactions of individual analysts and subgroups of analysts to both periodic and timely technical disclosures, and as a complement to periodic financial disclosure. We find that analysts are much slower to react to timely technical disclosures than they are to periodic financial disclosures. We find also that technical and financial disclosures complement each other. Furthermore, we find that there is a ‘hierarchy’ of analysts in this particular industry, as evidenced through the strength of reaction to timely technical disclosures. Finally, we find that lower speed in reacting to timely technical disclosures and a higher intensity in the use of timely technical disclosure (in conjunction with periodic financial disclosure) result in greater accuracy, and that more experienced analysts tend to be less accurate. We suggest that the findings may have implications for other industries such as Bio-Tech Pharma

Job Mismatches and Labour Market Outcomes: Panel Evidence on Australian University Graduates

The interpretation of graduate mismatch manifested either as overeducation or as overskilling remains problematical. This paper uses annual panel information on both educational and skills mismatches uniquely found in the HILDA survey to analyse the relationship of both mismatches with pay, job satisfaction and job mobility. We find that overeducation and overskilling are distinct phenomena with different labour market outcomes and that their combination results in the most severe negative labour market outcomes. Using panel methodology reduces strongly the size of many relevant coefficients, questioning previous cross-section results and suggesting the presence of considerable unobserved heterogeneity which varies by gender.overeducation, overskilling, wages, satisfaction, mobility

Repeatability and validity of the PowerRefractor and the Nidek AR600-A in an adult population with healthy eyes

We assessed the repeatability and validity of the PowerRefractor and the Nidek AR-600A autorefractor. This is the first independent study conducted on adults to evaluate the performance of these instruments in a laboratory setting. Fifty subjects (23 males and 27 females) aged 16 to 61 years (mean, 37 ± 12) participated in the study. The validity of the PowerRefractor and the Nidek autorefractor readings were determined by comparing them to subjective refraction. Measurements of refractive error were obtained from the two instruments on two separate occasions to assess their repeatability. The measured refractive error was converted into a dioptric power matrix for data analysis. No significant difference was found between the measurements obtained with the two instruments and the subjective refraction. The estimate of refractive error given by the two instruments was also found to be repeatable. In addition to measuring the refractive error, the PowerRefractor also offers the facility to measure eye position, pupil size, and dynamics of accommodation. We suggest some improvements to the PowerRefractor measurement technique to standardize its clinical use and to improve accuracy

Killing the cMSSM softly

We investigate the constrained Minimal Supersymmetric Standard Model (cMSSM) in the light of constraining experimental and observational data from precision measurements, astrophysics, direct supersymmetry searches at the LHC and measurements of the properties of the Higgs boson, by means of a global fit using the program Fittino. As in previous studies, we find rather poor agreement of the best fit point with the global data. We also investigate the stability of the electro-weak vacuum in the preferred region of parameter space around the best fit point. We find that the vacuum is metastable, with a lifetime significantly longer than the age of the Universe. For the first time in a global fit of supersymmetry, we employ a consistent methodology to evaluate the goodness-of-fit of the cMSSM in a frequentist approach by deriving p-values from large sets of toy experiments. We analyse analytically and quantitatively the impact of the choice of the observable set on the p-value, and in particular its dilution when confronting the model with a large number of barely constraining measurements. Finally, for the preferred sets of observables, we obtain p-values for the cMSSM below 10%, i.e. we exclude the cMSSM as a model at the 90% confidence level.Comment: 22 pages, 16 figures, to be submitted to EPJ

Increasing Spatial Fidelity and SNR of 4D-STEM using Multi-frame Data Fusion

4D-STEM, in which the 2D diffraction plane is captured for each 2D scan position in the scanning transmission electron microscope (STEM) using a pixelated detector, is complementing and increasingly replacing existing imaging approaches. However, at present the speed of those detectors, although having drastically improved in the recent years, is still 100 to 1,000 times slower than the current PMT technology operators are used to. Regrettably, this means environmental scanning-distortion often limits the overall performance of the recorded 4D data. Here we present an extension of existing STEM distortion correction techniques for the treatment of 4D-data series. Although applicable to 4D-data in general, we use electron ptychography and electric-field mapping as model cases and demonstrate an improvement in spatial-fidelity, signal-to-noise ratio (SNR), phase-precision and spatial-resolution

Emergency Care Handover (ECHO study) across care boundaries : the need for joint decision making and consideration of psychosocial history

Background: Inadequate handover in emergency care is a threat to patient safety. Handover across care boundaries poses particular problems due to different professional, organisational and cultural backgrounds. While there have been many suggestions for standardisation of handover content, relatively little is known about the verbal behaviours that shape handover conversations. This paper explores both what is communicated (content) and how this is communicated (verbal behaviours) during different types of handover conversations across care boundaries in emergency care. Methods: Three types of interorganisational (ambulance service to emergency department (ED) in ‘resuscitation’ and ‘majors’ areas) and interdepartmental handover conversations (referrals to acute medicine) were audio recorded in three National Health Service EDs. Handover conversations were segmented into utterances. Frequency counts for content and language forms were derived for each type of handover using Discourse Analysis. Verbal behaviours were identified using Conversation Analysis. Results: 203 handover conversations were analysed. Handover conversations involving ambulance services were predominantly descriptive (60%–65% of utterances), unidirectional and focused on patient presentation (75%–80%). Referrals entailed more collaborative talk focused on the decision to admit and immediate care needs. Across all types of handover, only 1.5%–5% of handover conversation content related to the patient's social and psychological needs. Conclusions: Handover may entail both descriptive talk aimed at information transfer and collaborative talk aimed at joint decision-making. Standardisation of handover needs to accommodate collaborative aspects and should incorporate communication of information relevant to the patient's social and psychological needs to establish appropriate care arrangements at the earliest opportunity

The Western Australian Family Connections Genealogical Project: Detection of familial occurrences of single gene and chromosomal disorders

Aim: To investigate using a Western Australian (WA) genealogical database for the identification of single gene and chromosome disorders among families. Method: Hospital admissions for single gene and chromosome disorders recorded during 2000–2006 were identified from the WA Hospital Morbidity Data System. The proportion of these conditions occurring in family groups was then identified using genealogical links created through the WA Family Connections Genealogical Project. Results: There were 216 family clusters among 11,303 people who were recorded as having a genetic or chromosomal disorder on their hospital admission record. The most common single gene conditions found to occur in multiple family members included blood clotting disorders such as Factor VIII deficiency and Von Willebrand’s disease, followed by cystic fibrosis, myotonic dystrophies, neurofibromatosis, tuberous sclerosis, and osteogenesis imperfecta. Discussion: Single gene disorders most commonly occurring in multiple family members have been identified using the WA Family Connections Genealogical Project. These disorders reflect the most common single gene disorders requiring hospital admission, but which are not fatal before reproductive age and do not result in a loss of fertility. They are also restricted to disorders with earlier onset, as the WA Family Connections Genealogical Project currently covers 2–3 of the most recent generations. This study demonstrates the utility of record linkage genealogies to identify kindred with genetic disorders, offering a rich resource of information for focused genetic epidemiological research
