Responding to the employability agenda: developments in the politics and international relations curriculum in English universities.

yesWith some of the lowest levels of graduate employability across university campuses, and the non-vocational nature of most Politics/International Relations (IR) undergraduate degree programmes, the discipline faces a huge challenge in responding to the increasingly prevalent employability agenda in higher education. Indeed, as Politics/IR students feel the burden of the £9000 annual student fee now charged by most universities,5 and an ever-more contracting and competitive jobs market, a review of existing employability training and learning in the Politics/IR curriculum in universities has never been so essential. As such, this paper – based on a Higher Education Agency (HEA) funded project, Employability Learning and the Politics/IR Curriculum – explores the employability learning provision in a cross-section of English higher education institutions (HEIs) with a view to identifying examples of good practice in order to generate reflection on how best the discipline can respond to the employability agenda. The original project maps how employability is ingrained in various Politics/IR departments’6 curriculum. Here we present some of our preliminary findings. The bulk of this paper is formed by a discussion of the results we have gathered to date. Before proceeding to the data, however, we begin this paper by setting out the background to the employability agenda. In particular, we seek to highlight the ways in which the employability agenda has developed and been framed in higher education, as well as detailing the statistics on graduate employability in Politics/IR in order to provide some quantitative context. In so doing we aim to lay out the scale of the practical and pedagogic challenges we face as a discipline. We then go on to discuss the methodology of the project, before finally presenting and analysing our findings

The history of stellar metallicity in a simulated disc galaxy

We explore the chemical distribution of stars in a simulated galaxy. Using simulations of the same initial conditions but with two different feedback schemes (McMaster Unbiased Galaxy Simulations – MUGS – and Making Galaxies in a Cosmological Context – MaGICC), we examine the features of the age–metallicity relation (AMR), and the three-dimensional age– [Fe/H]–[O/Fe] distribution, both for the galaxy as a whole and decomposed into disc, bulge, halo and satellites. The MUGS simulation, which uses traditional supernova feedback, is replete with chemical substructure. This substructure is absent from the MaGICC simulation, which includes early feedback from stellar winds, a modified initial mass function and more efficient feedback. The reduced amount of substructure is due to the almost complete lack of satellites in MaGICC. We identify a significant separation between the bulge and disc AMRs, where the bulge is considerably more metal-rich with a smaller spread in metallicity at any given time than the disc. Our results suggest, however, that identifying the substructure in observations will require exquisite age resolution, of the order of 0.25 Gyr. Certain satellites show exotic features in the AMR, even forming a ‘sawtooth’ shape of increasing metallicity followed by sharp declines which correspond to pericentric passages. This fact, along with the large spread in stellar age at a given metallicity, compromises the use of metallicity as an age indicator, although alpha abundance provides a more robust clock at early times. This may also impact algorithms that are used to reconstruct star formation histories from resolved stellar populations, which frequently assume a monotonically increasing AMR

A model for the operation of perovskite based hybrid solar cells:formation, analysis and comparison to experiment

This work is concerned with the modeling of perovskite based hybrid solar cells formed by sandwiching a slab of organic lead halide perovskite (CH3NH3PbI3?xClx) photo-absorber between (n-type) acceptor and (p-type) donor materials—typically titanium dioxide and spiro. A model for the electrical behavior of these cells is formulated based on drift-diffusion equations for the motion of the charge carriers and Poisson’s equation for the electric potential. It is closed by (i) internal interface conditions accounting for charge recombination/generation and jumps in charge carrier densities arising from differences in the electron affinity/ionization potential between the materials and (ii) ohmic boundary conditions on the contacts. The model is analyzed by using a combination of asymptotic and numerical techniques. This leads to an approximate—yet highly accurate—expression for the current-voltage relationship as a function of the solar induced photo- current. In addition, we show that this approximate current-voltage relation can be interpreted as an equivalent circuit model consisting of three diodes, a resistor, and a current source. For sufficiently small biases the device’s behavior is diodic and the current is limited by the recombination at the internal interfaces, whereas for sufficiently large biases the device acts like a resistor and the current is dictated by the ohmic dissipation in the acceptor and donor. The results of the model are also compared to experimental current-voltage curves, and good agreement is shown

Evidence and implications for exciton dissociation in lead halide perovskites

We have employed ultrafast transient-grating and two- dimensional electronic spectroscopy to probe dynamics of photo-excited CH3NH3PbI3 thin films with 16-fs temporal resolution. We distinctly capture the 30-fs decay of excitons, weakly coupled to the phonons

‘There's a Brand New Talk, but it's Not Very Clear’: Can the Contemporary EU Really be Characterized as Ordoliberal?

Ordoliberalism has undergone a dramatic resurgence as a characterization of the contemporary EU and its economic dimensions. Commentators have pointed to the ‘ordoliberalization’ of EU economic policy with Germany at its core, albeit with the latter taking the role of a ‘reluctant hegemon’. Perhaps as a result of this pervasive influence, some have claimed that the EU is itself ordoliberal, resting on a particular understanding of the relationship between ordoliberalism and an ‘economic constitution’. For this claim to be substantiated, the characterization of ordoliberalism needs to persist across time and the EU's law and policy-making spaces. In this article, we examine this proposition, and argue that the influence of ordoliberalism can help a richer understanding of the contemporary EU beyond the confines of the economic constitution and into its evolving legal system(s)

On the spacing distribution of the Riemann zeros: corrections to the asymptotic result

It has been conjectured that the statistical properties of zeros of the Riemann zeta function near z = 1/2 + \ui E tend, as $E \to \infty$, to the distribution of eigenvalues of large random matrices from the Unitary Ensemble. At finite $E$ numerical results show that the nearest-neighbour spacing distribution presents deviations with respect to the conjectured asymptotic form. We give here arguments indicating that to leading order these deviations are the same as those of unitary random matrices of finite dimension $N_{\rm eff}=\log(E/2\pi)/\sqrt{12 \Lambda}$, where $\Lambda=1.57314 ...$ is a well defined constant.Comment: 9 pages, 3 figure
