water and sewerage

description: Many studies of the water and sewerage industries place significant importance on the benefits of economies of scale and scope and how these relate to vertically integrated firms. We have re-examined the early literature on scale and scope economies and find that these studies do not implicitly preclude non-integrated firms from fully utilising assets for multi-product activities; they can still reap scope economies through trading in the open market. Further, we demonstrate difficulties in separating these two types of economies when assessing firm performance. Trade-offs between governance and production costs are a key issue in determining the value of vertically integrated firms that may undergo divestiture. We discuss the present policy debate regarding the optimal structure of the water and sewerage markets in England and Wales in the light of this, and recommend avenues of research that will help determine the optimal policy.
On The Beta-Function in N=2 Supersymmetric Yang-Mills Theory

description: The constraints of N=2 supersymmetry, in combination with several other quite general assumptions, have recently been used to show that N=2 supersymmetric Yang-Mills theory has a low energy quantum parameter space symmetry characterised by the discrete group $\gu$. We show that if one also assumes the commutativity of renormalization group flow with the action of this group on the complexified coupling constant $\ta$, then this is sufficient to determine the non-perturbative $β$-function, given knowledge of its weak coupling behaviour. The result coincides with the outcome of direct calculations from the Seiberg-Witten solution.

description: We consider the cosmological consequences of a network of superconducting cosmic strings. For strong enough current the period of friction domination never ends. Instead a plasma scaling solution is reached. We demonstrate that this gives rise to a very different cosmology than the usual horizon scaling solution. In particular the string network gives rise to adistinct imprint on the microwave sky, giving non-Gaussian features on much smaller angular scales. It also gives rise to a filament structure in string wakes. Because of the presence of the string magnetocylinder, the string magnetic field cannot create a primordial magnetic field. Similarly, it evades nucleosynthesis constraints. We also show that strings formed at the supersymmetry breaking scale can create the required baryon asymmetry of the universe.

description: Utilizing data on criminal charges lodged against candidates to the Fourteenth and Fifteenth Lok Sabha, India’s lower house of representatives, we study the conditions that resulted in approximately a quarter of members of parliament elected in 2004 and in 2009 facing or having previously faced criminal charges. Our results document that Indian political parties are more likely to select alleged criminal candidates when confronting greater electoral uncertainty and in parliamentary constituencies whose populations exhibit lower levels of literacy. We interpret the decisions of political parties to enlist known criminals as candidates as a function of the capacity of these candidates to intimidate voters. To substantiate this, we show that criminal candidates depress electoral turnout. In addition, our results suggest that India’s well-known incumbency disadvantage stems from the superior electoral performance of allegedly criminal candidates, who drive parliamentary incumbents from office. Our study raises questions for democratic theory, which claims that electoral competition improves accountability, and for the future of the Indian polity, which is experiencing a growing criminalization of the national political arena.

description: We present exact modal expansions for photonic systems including highly dispersive media. The formulas, based on a simple version of the Keldysh theorem, are very general since both permeability and permittivity can be dispersive, anisotropic, and even possibly non reciprocal. A simple dispersive test case where both plasmonic and geometrical resonances strongly interact exemplifies the numerical efficiency of our approach.

description: Context: At the end of their lives AGB stars are prolific producers of dust and gas. The details of this mass-loss process are still not understood very well. Herschel PACS and SPIRE spectra offer a unique way of investigating properties of AGB stars in general and the mass-loss process in particular. Methods: The HIPE software with the latest calibration is used to process the available PACS and SPIRE spectra of 40 evolved stars. The spectra are convolved with the response curves of the PACS and SPIRE bolometers and compared to the fluxes measured in imaging data of these sources. Custom software is used to identify lines in the spectra, and to determine the central wavelengths and line intensities. Standard molecular line databases are used to associate the observed lines. Because of the limited spectral resolution of the spectrometers several known lines are typically potential counterparts to any observed line. To help identifications the relative contributions in line intensity of the potential counterpart lines are listed for three characteristic temperatures based on LTE calculations and assuming optically thin emission. Result: The following data products are released: the reduced spectra, the lines that are measured in the spectra with wavelength, intensity, potential identifications, and the continuum spectra, i.e. the full spectra with all identified lines removed. As simple examples of how this data can be used in future studies we have fitted the continuum spectra with three power laws and find that the few OH/IR stars seem to have significantly steeper slopes than the other oxygen- and carbon-rich objects in the sample. As another example we constructed rotational diagrams for CO and fitted a two-component model to derive rotational temperatures.

The role of credit in international business cycles

Publisher: name: Faculty of Economics
Year: 2012

description: The recent financial crisis raises important issues about the role of credit in international business cycles and the transmission of financial shocks across country borders. This paper investigates the international spillover of US credit shocks and the importance of credit in explaining business cycle fluctuations using a global vector autoregressive (GVAR) model with credit, estimated over the period 1979Q2 to 2006Q4 for 26 major advanced and emerging economies. Results from the country-specific models reveal the importance of bank credit in explaining output growth, changes in inflation and long term interest rates in countries with developed banking sector. The generalized impulse response function (GIRF) for a one standard error negative shock to US real credit provides strong evidence of the spillover of US credit shock to the UK, the Euro area, Japan and other industrialized economies.

description: It is shown that the proton "spin crisis'' or "spin puzzle" can be understood by the relativistic effect of quark transversal motions due to the Melosh-Wigner rotation. The quark helicity $Δq$ measured in polarized deep inelastic scattering is actually the quark spin in the infinite momentum frame or in the light-cone formalism, and it is different from the quark spin in the nucleon rest frame or in the quark model. The flavor asymmetry of the Melosh-Wigner effect for the valence $u$ and $d$ quarks and the intrinsic sea $q \bar{q}$ pairs are also the important ingredients in a SU(6) quark-spectator-diquark model framework to understand the "spin puzzle". Such a picture of the spin structure can be tested by use of several simple relations to measure the quark spin distributions in the quark model.

The role of policy in energy transitions: lessons from the energy liberalisation era
Creators: name: Pollitt, Michael G.
Publisher: name: Faculty of Economics
Year: 2012
Subjects: Energy liberalisation

Energy transition

description: The aim of this paper is to discuss the period of energy privatisation and liberalisation which began in the 1980s within its wider historical context. The key issues are: what has been learned from this recent period, and how significant is it in the light of an energy transition to low carbon energy system by 2050? Energy liberalisation has led to positive and globally widespread but modest efficiency gains but a lack of clearly visible direct benefits to households in many countries. It has significantly improved the governance of monopoly utilities (via independent regulators), the prospects for competition and innovation, and the quality of policy instruments for environmental emissions control (through the emergence of trading mechanisms). We conclude that it is not liberalisation per se that will determine the movement towards a low carbon energy transition, but the willingness of societies to bear the cost, which will be significant no matter what the extent of liberalisation.

description: Fitting equilibrium dynamical models to observational data is an essential step in understanding the structure of the gaseous hot haloes that surround our own and other galaxies. However, the two main categories of models that are used in the literature are poorly suited for this task: (i) simple barotropic models are analytic and can therefore be adjusted to match the observations, but are clearly unrealistic because the rotational velocity $v_ϕ(R,z)$ does not depend on the distance $z$ from the galactic plane, while (ii) models obtained as a result of cosmological galaxy formation simulations are more realistic, but are impractical to fit to observations due to high computational cost. Here we bridge this gap by presenting a general method to construct axisymmetric baroclinic equilibrium models of rotating galactic coronae in arbitrary external potentials. We consider in particular a family of models whose equipressure surfaces in the $(R,z)$ plane are ellipses of varying axis ratio. These models are defined by two one-dimensional functions, the axial ratio of pressure $q_{\rm axis}(z)$ and the value of the pressure $P_{\rm axis}(z)$ along the galaxy's symmetry axis. These models can have a rotation speed $v_ϕ(R,z)$ that realistically decreases as one moves away from the galactic plane, and can reproduce the angular momentum distribution found in cosmological simulations. The models are computationally cheap to construct and can thus be used in fitting algorithms. We provide a python code that given $q_{\rm axis}(z)$, $P_{\rm axis}(z)$ and $Φ(R,z)$ returns $ρ(R,z)$, $T(R,z)$, $P(R,z)$, $v_ϕ(R,z)$. We show a few examples of these models using the Milky Way as a case study.

Self-Disconnection Among Pre-Payment Customers - A Behavioural Analysis

description: In this paper, we revisit the problem of self-disconnection among prepayment energy customers. Using metering data from 2.3 million electricity pre-payment customers, we study how often households with an electricity pre-payment meter tend to self-disconnect over the course of a year - and why they do so. What we find is that, in any given year, the majority of households (ca. 78%) do not self-disconnect; ca. 12% self-disconnect once; ca. 3% self disconnect more often than four times. We also find that most self disconnections (ca. 62%) last for less than one day; between 72% and 82% last for less than two days; 12%-18% last for more than 3 days. As for the main driver of self-disconnection, we identify financial constraints. This suggests that it is likely to be difficult/expensive to reduce the total number of self-disconnections. In the last part of the paper, we argue, however, that it may (still) be possible to reduce the negative impact of self-disconnection in a relatively inexpensive way - at least to some extent - by helping households to better smooth their self disconnections over the course of a year.
Testing CAPM with a Large Number of Assets (Updated 28th March 2012)

description: (DISCLAIMER: Not all mathematical symbols in the abstract will display properly - please see the abstract in the pdf). This paper is concerned with testing the time series implications of the capital asset pricing model (CAPM) due to Sharpe (1964) and Lintner (1965), when the number of securities, N, is large relative to the time dimension, T, of the return series. Two new tests of CAPM are proposed that exploit recent advances on the analysis of large panel data models, and are valid even if N is much larger than T. When the errors are Gaussian and cross sectionally independent, a test, denoted by Ĵα,ı, is proposed which is N(0; 1) as N→∞, with T fixed. Even when the errors are non-Gaussian we are still able to show that Ĵα,ı, tends to N(0; 1) so long as the errors are cross-sectionally independent and N/T³→0, with N and T ! 1, jointly. In the case of cross sectionally correlated errors, using a threshold estimator of the average squares of pair-wise error correlations, a modified version of Ĵα,ı,, denoted by Ĵα,2, is proposed. Small sample properties of the tests are compared using Monte Carlo experiments designed specifically to match the correlations, volatilities, and other distributional features of the residuals of Fama-French three factor regressions of individual securities in the Standard Poor 500 index. Overall, the proposed tests perform best in terms of power, with empirical sizes very close to the chosen nominal value even in cases where N is much larger than T. The Ĵα,2 test (which allows for non-Gaussian and weakly cross correlated errors) is applied to all securities in the S&P 500 index with 60 months of return data at the end of each month over the period September 1989-September 2011. Statistically significant evidence against Sharpe-Lintner CAPM is found mainly during the recent financial crisis. Furthermore, a strong negative correlation is found between a twelve-month moving average p-values of the Ĵα,2 test and the returns of long/short equity strategies relative to the return on S&P 500 over the period December 2006 to September 2011, suggesting that abnormal profits are earned during episodes of market inefficiencies

description: The law surrounding third party nuclear liability is important to all parties in the nuclear supply chain whether they are providing decommissioning services, project management expertise or a new reactor. This paper examines third party nuclear liability, and in particular, in relation to a Supplier in the nuclear energy sector in the United Kingdom (UK). The term "Supplier" is used in this paper and, depending on the context, is intended to cover all parties in the supply chain providing services, equipment or technology (e.g. the EPC contractor, the reactor vender, the owner engineer, architect engineer, or the Parent Body Organisation responsible for decommissioning one the UK legacy nuclear installations). With a return to nuclear new build expected in the UK, the clarification of the position of a Supplier and their potential to be liable for nuclear damage is of vital importance for a functioning nuclear supply chain. The research explores the nuclear liability legislation in the UK and identifies the gaps and limitations in existence. The latter problems pose a risk for the Suppliers to operators in the nuclear energy industry, and consequently some approaches that can mitigate those risks are advanced and assessed. The nuclear liability regime in the UK is largely based on international conventions and hence, the risks posed to the Supplier in the UK also exist for Suppliers in other countries. There are resource shortages already in the nuclear energy industry, and currently the Supplier to the nuclear industry is over exposed. This situation needs to be resolved and a new legal definition of nuclear damage enacted. Further, the level of liability exposure for a UK Supplier involved in a nuclear project outside the UK needs to be reviewed as there remains too much ambiguity regarding liability in an international nuclear law context.
Econometric Modelling of World Oil Supplies: Terminal Price and the Time to Depletion

description: This paper develops a novel approach by which to identify the price of oil at the time of depletion; the so-called terminal price of oil. It is shown that while the terminal price is independent of both GDP growth and the price elasticity of energy demand, it is dependent on the world real interest rate and the total life-time stock of oil resources, as well as on the marginal extraction and scarcity cost parameters. The theoretical predictions of this model are evaluated using data on the cost of extraction, cumulative production, and proven reserves. The predicted terminal prices seem sensible for a range of parameters and variables, as illustrated by the sensitivity analysis. Using the terminal price of oil, we calculate the time to depletion, and determine the extraction and price profiles over the life-time of the resource. The extraction profiles generated seem to be in line with the actual production and the predicted prices are generally in line with those currently observed.

description: Grand unified theories can admit cosmic strings with fermion zero modes. Such zero modes result in the string being current-carrying and the formation of stable remnants, vortons. However, the string zero modes do not automaticall survive subsequent phase transitions. In this case the vortons dissipate. It is possible that the dissipating cosmic vortons create the observed baryon asymmetry of the universe. We show that fermion zero modes are an automatic consequence cosmic strings in supersymmetric theories. Since supersymmetry is not observed in nature, we consider possible supersymmetry breaking terms. Some of these terms result in the zero modes being destroyed. We calculate the baryon asymmetry generated by the consequent dissipating cosmic vortons. If the supersymmtry breaking scale is high enough, then the dissipating cosmic vortons could account for the observed baryon asymmetry.

description: We performed low-temperature de Haas-van Alphen (dHvA) effect measurements on a Ce$_{1-x}$Nd$_x$CoIn$_5$ series, for x = 0.02, 0.05, 0.1, and 1, down to T = 40 mK using torque magnetometry in magnetic felds up to 35 T. Our results indicate that a Fermi-surface (FS) reconstruction occurs from a quasi-two-dimensional (2D) topology for Nd-2% to a rather three-dimensional (3D) for Nd-5%, thus reducing the possibility of perfect FS nesting. The FS evolves further with increasing Nd content with no observed divergence of the effective mass between Nd-2% and 10%, consistent with the crossing of a spin density wave (SDW) type of quantum critical point (QCP). Our results elucidate the origin of the Q-phase observed at the 5% Nd-doping level [Raymond et al., J. Phys. Soc. Jpn. 83, 013707 (2014)].

description: Microtubules are biological protein polymers with critical and diverse functions. Their structures share some similarities with photosynthetic antenna complexes, particularly in the ordered arrangement of photoactive molecules with large transition dipole moments. As the role of photoexcitations in microtubules remains an open question, here we analyze tryptophan molecules, the amino acid building block of microtubules with the largest transition dipole strength. By taking their positions and dipole orientations from realistic models capable of reproducing tubulin experimental spectra, and using a Hamiltonian widely employed in quantum optics to describe light-matter interactions, we show that such molecules arranged in their native microtubule configuration exhibit a superradiant ground state, which represents an excitation fully extended on the chromophore lattice. We also show that such a superradiant ground state emerges due to supertransfer coupling between the ground states of smaller blocks of the microtubule. In the dynamics we find that the spreading of excitation is ballistic in the absence of external sources of disorder and strongly dependent on initial conditions. The velocity of photoexcitation spreading is shown to be enhanced by the supertransfer effect with respect to the velocity one would expect from the strength of the nearest-neighbor coupling between tryptophan molecules in the microtubule. Finally, such structures are shown to have an enhanced robustness to static disorder when compared to geometries that include only short-range interactions. These cooperative effects (superradiance and supertransfer) may induce ultra-efficient photoexcitation absorption and could enhance excitonic energy transfer in microtubules over long distances under physiological conditions.

Towards conditions for black-hole singularity-resolution in asymptotically safe quantum gravity

description: We explore the fate of the curvature singularity of Schwarzschild (deSitter) black holes in asymptotically safe quantum gravity. Specifically, we upgrade the classical spacetime by including the running of the Newton coupling and cosmological constant. In this setting, the antiscreening character of the gravitational interaction can remove the singularity, yet a nonzero value of the cosmological constant in the ultraviolet appears to reintroduce it. We find hints that a finite value of the cosmological constant in the infrared is compatible with singularity resolution provided that the cosmological constant is driven to zero fast enough in the ultraviolet. We compare the corresponding bounds on the critical exponents to the literature.

description: We present an analysis of the neutrino oscillation solutions of the solar neutrino problem in the framework of four-neutrino mixing where a sterile neutrino is added to the three standard ones. We perform a fit to the full data set corresponding to the 825-day Super-Kamiokande data sample as well as to Chlorine, GALLEX and SAGE and Kamiokande experiments. In our analysis we use all measured total event rates as well as all Super-Kamiokande data on the zenith angle dependence and the recoil electron energy spectrum. We consider both transitions via the Mikheyev-Smirnov-Wolfenstein (MSW) mechanism as well as oscillations in vacuum (just-so) and find the allowed solutions for different values of the additional mixing angles. This framework permits transitions into active or sterile neutrinos controlled by the additional parameter $\cos^2(\vartheta_{23}) \cos^2(\vartheta_{24})$ . We discuss the maximum allowed values of this additional mixing parameter for the different solutions.

Exponent of Cross-sectional Dependence: Estimation and Inference
Creators: name: Bailey, Natalia

Publisher: name: Faculty of Economics
Year: 2012

description: (DISCLAIMER: Not all mathematical symbols in the abstract will display properly - please see the abstract in the pdf). An important issue in the analysis of cross-sectional dependence which has received renewed interest in the past few years is the need for a better understanding of the extent and nature of such cross dependencies. In this paper we focus on measures of cross-sectional dependence and how such measures are related to the behaviour of the aggregates defined as cross-sectional averages. We endeavour to determine the rate at which the cross-sectional weighted average of a set of variables appropriately demeaned, tends to zero. One parameterisation sets this to be 0(N2α-2), for 1/2<α≤1. Given the fashion in which it arises, we refer to α as the exponent of cross-sectional dependence. We derive an estimator of α from the estimated variance of the cross-sectional average of the variables under consideration. We propose bias corrected estimators, derive their asymptotic properties and consider a number of extensions. We include a detailed Monte Carlo study supporting the theoretical results. Finally, we undertake an empirical investigation of α using the S&P 500 data-set, and a large number of macroeconomic variables across and within countries
Proton-nucleus cross section at high energies
Creators: name: Wibig, Tadeusz

Year: 1998
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Cross sections for proton inelastic collision with different nuclei are described within the Glauber and multiple scattering approximations. A significant difference between approximate `Glauber' formula and exact calculations with a geometrical scaling assumption for very high-energy cross section is shown. Experimental values of proton-proton cross sections obtained using extensive air shower data are based on the relationship of proton-proton and respective proton-air absorption cross sections. According to obtained results values reported by the Akeno and Fly's Eye experimental groups are about 10% overestimated. The proper energy dependence of absorption cross section for collisions with air nuclei is of a great importance for studies of high energy cosmic rays using the Monte Carlo technique.

Fiscal Policy in an Unemployment Crisis
Creators: name: Rendahl, Pontus
Publisher: name: Faculty of Economics
Year: 2012
Subjects: Fiscal multiplier
Fiscal policy
Liquidity trap
Unemployment inertia

description: This paper argues that the effectiveness of fiscal policy may increase markedly during periods of low nominal interest rates and high, persistent, unemployment. An increase in government spending boosts economic activity and reduces the unemployment rate both in the present and in the future. As a less disconcerting future spurs a rise in private consumption, unemployment falls even further and triggers an additional rise in private demand, and so on. In a stylized model, I show that the marginal impact of government spending on output is equal to the reciprocal of the elasticity of intertemporal substitution. In a more realistic framework, the effect is somewhat attenuated and displays significant nonlinearities with respect to the depth of the crisis as well as the size of the stimulus package. But in a severe recession with an unemployment rate of eight percent or above, the fiscal multiplier is equal to 1.5.
FCNC transitions $c\to uγ$ and $s\to dγ$ in $B_c\to B_u^*γ$ and $B_s\to B_d^*γ$ decays

description: We propose the $B_c\to B_u^*γ$ decay as the most suitable probe for the flavour changing neutral transition $c\to uγ$. We estimate the short and long distance contributions to this decay within the standard model and we find them to be comparable; this is in contrast to radiative decays of $D$ mesons, that are completely dominated by the long distance contributions. Since the $c\to uγ$ transition is very sensitive to the physics beyond the standard model, the standard model prediction $Br(B_c\to B_u^*γ)\sim 10^{-8}$ obtained here opens a new window for future experiments. The detection of $B_c\to B_u^*γ$ decay at branching ratio well above $10^{-8}$ would signal new physics. In addition we study the $s\to dγ$ transition in $B_s\to B_d^*γ$ decay and we find it to be dominated by the long distance contribution. We use the Isgur-Scora-Grinstein-Wise (ISGW) constituent quark model for the calculation of these decays.

Loyalty for Sale? Military Spending and Coups d'Etat

Subjects: Coups

Military spending
Political economy

description: Coups d'etat continue to be common around the world, often leading to changes in leaders and institutions. We examine the relationship between military spending and coups and find that (i) successful coups increase military spending by more than failed attempts, and (ii) coups are more likely when military spending as a share of GDP is relatively low. Our identification strategy exploits the conditional independence between a coup's outcome and the change in military spending that follows it. We interpret this as evidence that the military may stage coups in order to increase its funding, and rule out several alternative mechanisms.
Plastic energies in layered superconductors

Publisher: name: arXiv
Year: 1995
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We estimate the energy cost associated with two pancake vortices colliding in a layered superconductor. It is argued that this energy sets the plastics energy scale and is the analogue of the crossing energy for vortices in the continuum case. The starting point of the calculation is the Lawrence-Doniach version of the Ginzburg-Landau free energy for type-II superconductors. The magnetic fields considered are along the c-direction and assumed to be sufficiently high that the lowest Landau level approximation is valid. For Bi-2212, where it is know that layering is very important, the results are radically different from what would have been obtained using a three-dimensional anisotropic continuum model. We then use the plastic energy for Bi-2212 to successfully explain recent results from Hellerqvist {\em et al.}\ on its longitudinal resistance.

description: We study the anomalous Josephson effect, as well as the dependence on the direction of the critical Josephson current, in an S/N/S junction, where the normal part is realized by alternating spin-orbit coupled and ferromagnetic layers. We show that to observe these effects it is sufficient to break spin rotation and time reversal symmetry in spatially separated regions of the junction. Moreover, we discuss how to further improve these effects by engineering multilayers structures with more that one couple of alternating layers.

description: The principal angles between binary collision subspaces in an $N$-billiard system in $d$-dimensional Euclidean space are computed. These angles are computed for equal masses and arbitrary masses. We then provide a bound on the number of collisions in the planar 3-billiard system problem. Comparison of this result with known billiard collision bounds in lower dimensions is discussed.
