Ethnic parity in labour market outcomes for benefit claimants

We use UK administrative data to estimate the differential in labour market outcomes between Ethnic Minority benefit claimants and otherwise identical Whites. In many cases, Minorities and Whites are simply too different for satisfactory estimates to be calculated and results are sensitive to the methodology used. This calls into question previous results based on simple regression techniques, which may hide the fact that observationally different ethnic groups are being compared by parametric extrapolation. For some groups, however, we could calculate satisfactory results. In these cases, large and significant raw penalties almost always disappear once we appropriately control for pre-inflow characteristics.Ethnic, employment, benefit, discrimination, matching

Ethnic parity in labour market outcomes for benefit claimants in Great Britain

Accurate estimates of the extent of ethnic parity amongst benefit claimants are very important for policymakers who provide interventions for these groups. We use new administrative data on benefit claimants in Great Britain to document differences in labour market outcomes between Ethnic Minority and White claimants, both before and after controlling for rich observable characteristics. We do so using a variety of methods, from OLS to propensity score matching to difference-in-differences. We find that, in many cases, Minorities and Whites are simply too different for satisfactory estimates to be calculated, and that results are sensitive to the methodology used. This calls into question previous results based on simple regression techniques, which may hide the fact that observationally different ethnic groups are being compared by parametric extrapolation. For Income Support and Incapacity Benefit claimants, however, we could calculate satisfactory results. For these groups, large and significant raw penalties almost always disappear once we appropriately control for pre-inflow characteristics.Non-response, bias, school survey, data linkage, PISA

What treatment approach to intrapartum maternal fever has the best fetal outcomes?

A combination of beta-lactam and amino-glycoside antibiotics are the recommended empiric agents for the treatment of acute chorioamnionitis, given that no head-to-head trials exist (strength of recommendation [SOR]: C, based on expert opinion). Intrapartum antibiotic treatment is not superior to postpartum antibiotics for reducing neonatal sepsis and pneumonia (SOR: C, based on patient-oriented, underpowered randomized trials)

Investing in Well-being: An Analytical Framework

The NZ Treasury is currently engaged in a project to identify cost-effective interventions to improve outcomes for children and young adults in order to maximise the value of government expenditures across the social sector. The central aim of this paper is to provide an empirically-robust framework to compare intervention across a range of social sectors. There are two key components to the framework. The first is a life-course view of child development that emphasises that experiences and influences in childhood can affect well-being throughout life. The second component involves viewing social expenditures as investments addressed at achieving particular outcomes, typically directed at enhancing well-being. The paper presents evidence from a review of the literature on how the process and experiences of childhood have a later impact on wellbeing; how child development and outcomes are influenced by individual, family and communal factors and how risk and resilience can be used to indicate that an individual is at increased or decreased risk of negative outcomes. Case studies of youth suicide, teenage pregnancy, educational underachievement and youth inactivity provide evidence about what interventions work using key empirical findings from the literature.Well-being; social investment; life-course; child development; child and adult outcomes; portfolio; intervention

Innovative approaches to teaching mathematics in higher education: a review and critique

This paper provides a snapshot of emerging trends in mathematics teaching in higher education for STEM subjects (Science, Technology, Engineering and Mathematics). Overwhelmingly, papers identify a focus on conceptual understandings of mathematics in comparison to understanding that is instrumental or procedural. Calls for reform of mathematics teaching have been the basis for a range of studies; responses to these calls have embraced innovative methods for implementing changes in learning and teaching of mathematics, sometimes rooted in constructivist ideology. Observed trends have been categorised in six groups. In many studies, technology is being used as an enabler of reforms. Constraints to implementing new approaches in mathematics teaching are indicated. Discussion of contemporary research questions that could be asked as a result of the shift towards teaching mathematics in innovative ways is provided and is followed by a critique of the underlying theoretical positions, essentially that of constructivism

The Norse waterways of West Mainland Orkney, Scotland

This study was funded by BA/Leverhulme Small Research Grants 2017-18 Round.Norse place-names for farms, individual landscape features and general landscape areas are ubiquitous throughout the Orkney Islands. These have an origin during the mediaeval period AD790–1350 when Orkney was ruled by Scandinavian earls. The oldest referenced maps for the parish of Harray (West Mainland, Orkney) suggests that in the past significant waterways crossed wetlands extending between the Loch of Harray and Houseby in an area associated with the earldom power base at Birsay. Subsequent drainage projects, changes in climate and sea level have since resulted in the loss of the waterways. An investigation of the wetlands using geophysical and geological analysis provided a reconstruction of the palaeo-environments. Comparison with place-names of significance allowed interpretation of possible routeways along navigable waters by shallow-draught Viking-Age vessels. The results allow for re-drawing the map of Norse Orkney and postulation of produce transfer corridors from estates in the south to the power centre at Birsay.PostprintPeer reviewe

Classical simulation of noninteracting-fermion quantum circuits

We show that a class of quantum computations that was recently shown to be efficiently simulatable on a classical computer by Valiant corresponds to a physical model of noninteracting fermions in one dimension. We give an alternative proof of his result using the language of fermions and extend the result to noninteracting fermions with arbitrary pairwise interactions, where gates can be conditioned on outcomes of complete von Neumann measurements in the computational basis on other fermionic modes in the circuit. This last result is in remarkable contrast with the case of noninteracting bosons where universal quantum computation can be achieved by allowing gates to be conditioned on classical bits (quant-ph/0006088).Comment: 26 pages, 1 figure, uses wick.sty; references added to recent results by E.
