description: We consider bandwidth selection for the kernel estimator of conditional density with one explanatory variable. Several bandwidth selection methods are derived ranging from fast rules-of-thumb which assume the underlying densities are known to relatively slow procedures which use the bootstrap. The methods are compared and a practical bandwidth selection strategy which combines the methods is proposed. The methods are compared using two simulation studies and a real data set.

description: This paper considers the construction of model selection procedures based on choosing the model with the largest maximised log-likelihood minus a penalty, when key parameters are restricted to be in a closed interval. The approach adopted is based on King et al.' s (1995) representative models method with the use of the parametric bootstrap to handle nuisance parameters. The method is illustrated by application to two model selection problems in the context of Box-Cox transformations and the linear regression model. Simulation results for both problems indicate that the new procedure clearly dominates existing procedures in terms of having higher probabilities of correctly selecting the true model.

description: In the current work, a novel class of (Ca0.9Si0.1)Al2O6:Eu2+,Nd3+ long persistent phosphor was synthesized using high-temperature (1000-1500oC) solid-state reaction method. Further, the phosphor material was formulated into a phosphorescent ink using epoxy based colloidal suspension. Interestingly the phosphorescent ink absorbs ambient energies such as white light from D65 and tungsten lamps, sunlight, artificial lights etc., stores up the energy and emit as efficient blue colored photoluminescence (PL) apparently visible for many hours for dark adapted human eye. However, the optimum PL emission centred at ~450 nm has been registered at ~365 nm excitation that is attributed to transitions from 4f65d1 to 4f7 energy levels of Eu2+ ions. The longer persistence of PL aroused due to trapping and de-trapping of holes at Nd3+ sites situated proximate to valance band. In the optimised stoichiometric composition of the phosphor, the persistence lasted for >4 hours in extremely dark conditions. Furthermore, the phenomenon of long persistence enables to create/design unique hidden markings on goods and certificates using quick response (QR) code patterns. Systematic studies have been performed on various templates kept under UV (~365 nm) excitation to identify fake currencies, barcodes and combat counterfeiting effectively.

description: In this paper we propose a new test procedure with more general steady state information to test the convergence hypothesis for a specific economy. We consider a model where demeaned per capita output of an economy is a function of time trend and then set the convergence hypothesis as negative average slope of that model. Applying the new procedure to 22 OECD countries we find strong evidence of convergence for 20 countries towards their average level. We also consider the per capita output of USA as a common steady state level for OECD countries. Then using the per capita output gap from USA we test the convergence hypothesis for an individual economy. This approach also shows strong evidence in favour of convergence towards the USA for most economies. France and Iceland do not converge towards the average level of OECD countries although they are converging towards USA. Australia and New Zealand are showing the opposite pattern as they are converging towards the average level but moving away from USA. This study also points out why using standard unit root tests with Bernard and Durlauf's (1995) definition of convergence is inappropriate.
Einstein boundary conditions in relation to constraint propagation for the initial-boundary value problem of the Einstein equations

description: We show how the use of the normal projection of the Einstein tensor as a set of boundary conditions relates to the propagation of the constraints, for two representations of the Einstein equations with vanishing shift vector: the ADM formulation, which is ill posed, and the Einstein-Christoffel formulation, which is symmetric hyperbolic. Essentially, the components of the normal projection of the Einstein tensor that act as non-trivial boundary conditions are linear combinations of the evolution equations with the constraints that are not preserved at the boundary, in both cases. In the process, the relationship of the normal projection of the Einstein tensor to the recently introduced ``constraint-preserving'' boundary conditions becomes apparent.

description: A new simple formula is found to correct the underestimation of the standard deviation for total lead time demand when using simple exponential smoothing. The traditional formula for the standard deviation of lead time demand is to multiply the standard deviation for the one-period-ahead forecast error (estimated by using the residuals) by the square root of the number of periods in the lead time. It has been shown by others that the traditional formula significantly underestimates variation in the lead time demand when the mean of the process is somewhat changing and simple exponential smoothing is appropriate. This new formula allows one to see readily the significant size of the underestimation of the traditional formula and can easily be implemented in practice. The formula is derived by using a state space model for simple exponential smoothing.

description: We present the discovery of NGTS J214358.5-380102, an eccentric M-dwarf binary discovered by the Next Generation Transit Survey. The system period of 7.618 days is greater than many known eclipsing M-dwarf binary systems. Its orbital eccentricity of $0.323^{+0.0014}_{-0.0037}$, is large relative to the period and semi-major axis of the binary. Global modelling of photometry and radial velocities indicate stellar masses of $M_A$=$0.426 ^{+0.0056}_{-0.0049}$, $M_B$=$0.455 ^{+0.0058}_{-0.0052}$ and stellar radii $R_A$=$0.461 ^{+0.038}_{-0.025}$ $R_B$=$0.411 ^{+0.027}_{-0.039}$, respectively. Comparisons with stellar models for low mass stars show that one star is consistent with model predictions whereas the other is substantially oversized. Spectral analysis of the system suggests a primary of spectral type M3V, consistent with both modelled masses and radii, and with SED fitting of NGTS photometry. As the most eccentric eclipsing M-dwarf binary known, NGTS J214358.5-380102 provides an interesting insight into the strength of tidal effects in the circularisation of stellar orbits.

description: This paper considers residuals for time series regression. Despite much literature on visual diagnostics for uncorrelated data, there is little on the autocorrelated case. In order to examine various aspects of the fitted time series regression model, three residuals are considered. The fitted regression model can be checked using orthogonal residuals; the time series error model can be analysed using marginal residuals; and the white noise error component can be tested using conditional residuals. When used together, these residuals allow identification of outliers, model mis-specification and mean shifts. Due to the sensitivity of conditional residuals to model mis-specification, it is suggested that the orthogonal and marginal residuals be examined first.
title: Bonded Labour in Nepal: Life and Work of Children in Communities
Creators: name: Giri, Birendra Raj
Publisher: name: The Open University
Year: 2010

description: This dissertation focuses on the lives of Nepali children working under haliya and kamaiya systems. The former refers to people from various castes and ethnicities, including Musahar, predominately found in the far-western hill region of Nepal, who work as 'temporary' agricultural labourers for kisan (small landowners) to meet their daily needs, and also, often, to pay their debts. The latter exclusively implies ethnic Tharu families from the western Tarai districts, who have been tied to their kisan for generations. The United Nations Working Group on Contemporary Forms of Slavery calls those people bonded labourers.

Although detailed research is almost non-existent, especially concerning haliya practices, advocacy groups and the International Labour Organisation argue that bonded labour has continued even after the government banned it in 2000. Children in particular have increasingly taken on the activities previously carried out by their parents. This study was carried out in the pseudonymous Bayibab and Nayajib settlements of Morang and Bardiya districts, respectively, exploring Musahar/Tharu children's bondedness at work, including their motives and rationale for entering into bonded labour, the ways in which they understand it and its significance in the context of their lives. I conducted a series of semi-structured interviews and group discussions with 58 haliya/kamaiya children (ages ranging from 8 to 16 years), applying 'child-friendly' research techniques in order to uncover their everyday life-worlds from their own perspectives. My interviews with, and observations of, working children, parents, and kisan also provided a rich source of ethnographic data concerning bonded child labour.

This research shows the complexity in Musahar/Tharu children's constructions of haliya/kamaiya systems. It includes their assessment of their own health and well-being and their current and future prospects while being engaged in bonded child labour.

description: We apply deep-learning techniques to the string landscape, in particular, $SO(32)$ heterotic string theory on simply-connected Calabi-Yau threefolds with line bundles. It turns out that three-generation models cluster in particular islands specified by deep autoencoder networks and k-means++ clustering. Especially, we explore mutual relations between model parameters and the cluster with densest three-generation models (called "3-generation island"). We find that the 3-generation island has a strong correlation with the topological data of Calabi-Yau threefolds, in particular, second Chern class of the tangent bundle of the Calabi-Yau threefolds. Our results also predict a large number of Higgs pairs in the 3-generation island.

description: O presente estudo analisa algumas razões pelas quais se deve enfocar, atualmente, a questão agrária brasileira a partir de situações concretas diferentes daquelas de algumas décadas atrás, com ênfase principal no preço da terra e na formação de novos grupos com interesses na manutenção da atual estrutura agrária. Uma verificação fundamental foi a forte tendência crescente dos preços de venda no período 1966-78, principalmente em 1972-75, determinando-se o aumento da participação de elementos não ligados à produção na formação do preço da terra, elementos esses gerados pelos modelos de desenvolvimento econômico vigente no período analisado. Duas principais conclusões do trabalho foram que o monopólio da terra no Brasil foi reassegurado, diminuindo as possibilidades dos produtores diretos terem acesso a ela, e que houve a formação de novos grupos ligados ao capital industrial o agrário, interessados na manutenção da atual estrutura agrária.
Photoevaporation of Cosmological Minihalos during Reionization

description: We present the first gas dynamical simulations of the photoevaporation of cosmological minihalos overtaken by the ionization fronts which swept through the IGM during reionization in a LCDM universe, including the effects of radiative transfer. We demonstrate the phenomenon of I-front trapping inside minihalos, in which the weak, R-type fronts which traveled supersonically across the IGM decelerated when they encountered the dense, neutral gas inside minihalos, becoming D-type I-fronts, preceded by shock waves. For a minihalo with virial temperature T_vir < 10^4 K, the I-front gradually burned its way through the minihalo which trapped it, removing all of its baryonic gas by causing a supersonic, evaporative wind to blow backwards into the IGM, away from the exposed layers of minihalo gas just behind the advancing I-front. Such hitherto neglected feedback effects were widespread during reionization. N-body simulations and analytical estimates of halo formation suggest that sub-kpc minihalos such as these, with T_vir < 10^4 K, were so common as to cover the sky around larger-mass source halos and possibly dominate the absorption of ionizing photons. This means that previous estimates of the number of ionizing photons per H atom required to complete reionization which neglected this effect may be too low. Regardless of their effect on the progress of reionization, however, the minihalos were so abundant that random lines of sight thru the high-z universe should encounter many of them, which suggests that it may be possible to observe the processes described here in the absorption spectra of distant sources.

description: The opportunity of steady development is one of the major features of any enterprise in conditions of the market economy. Only a set of subsequent trend analysis, preliminary long-term and intermediate term, and also operative analysis are capable to provide an opportunity to achieve a truly steady development of the company. The major factor for the assessment of the opportunity of the enterprise development is its potential. The creation of the system of consolidated accountancy can be considered as an important factor in estimating the financial results and financial stability of holding companies and for analyzing the opportunities of their perspective development.

description: O trabalho aborda o inovador uso complementar da mandioca e da cana-de-açúcar para a produção de álcool. Ambas estas matérias-primas já foram usadas no passado, na produção de álcool etílico. Trata-se de procurar ver como elas se comportam hoje, dada a nova realidade histórica e tecnológica com que nos deparamos. O uso complementar do binômio cana/mandioca (a mandioca ou suas raspas utilizadas na entressafra da cana) permite expandir em torno de 50% a produção anual de álcool, com a mesma capacidade de destilação atualmente instalada e, portanto, sem acréscimos significativos de capital destinado à etapa industrial da produção de álcool. A menor exigência de solo por parte da cultura da mandioca, e, mais ainda, caso seja usada a raspa como insumo industrial, permite a utilização de terras de mais baixo custo de oportunidade, que não poderiam ser usadas para a plantação da cana. Assim, essas terras poderiam ser incorporadas à produção de energia, expandindo os benefícios do PROÁLCOOL a regiões e populações até hoje não atingidas. Outros aspectos da complementaridade, como, por exemplo, a possibilidade de aproveitamento econômico do bagaço no processo de obtenção do álcool via mandioca, são analisados no artigo. O estudo, ainda, conduz à necessidade de se proceder à análise das principais variáveis e dos aspectos que devem ser objeto de atenção numa pesquisa que vise a orientar as ações a serem desenvolvidas no sentido de racionalizar a política energética, mormente no que diz respeito ao combustível líquido vegetal destinado a substituir combustíveis de origem mineral. Assim, observa-se a necessidade de analisar a expansão da produção de álcool: por aumento da área cultivada, mantendo as práticas atuais; através da produção extra de melaço no período da safra da cana, para a produção de álcool na entressafra, via colheita da cana por todo o ano; com o uso complementar da mandioca; e através do uso complementar da raspa de mandioca. Cada uma destas alternativas deve ser analisada à luz dos custos privados e sociais de produção e estocagem, levando-se em conta os problemas de sazonalidade associados, e sua contribuição para o emprego em geral e, especialmente, para o emprego no campo, de mão-de-obra não qualificada para trabalhos urbanos.

description: The presence of nuisance parameters causes unwanted complications in statistical and econometric inference procedures. A number of modified likelihood and message length functions have been developed for better handling of nuisance parameters but they are not equally efficient. In this paper, we empirically compare different modified likelihood and message length functions in the context of estimation and testing of parameters from linear regression disturbances that follow either first-order moving average or first-order autoregressive error processes. The results show that estimators based on the conditional profile likelihood and tests based on the marginal likelihood are best. If there is a minor identification problem, the sizes of the likelihood ratio and Wald tests based on simple message length functions are best. The true sizes of the Lagrange multiplier tests based on message length functions are rather poor because the score functions of message length functions are biased.

description: We carry out a feasibility study toward a lattice QCD calculation of the neutron electric dipole moment (NEDM) in the presence of the $θ$ term using two different approaches. In the first method, we calculate the CP-odd electromagnetic form factor $F_3$, which becomes the NEDM in the zero momentum transfer limit. At the first order in $θ$, we derive a formula connecting the lattice three-point function to the CP-odd electromagnetic form factor. In the second method we directly extract the NEDM from the energy difference between spin-up and spin-down neutron states in the presence of a constant electric field, without expanding a small but non-zero $θ$. We test both approaches numerically, employing the domain-wall quark action with the RG improved gauge action in quenched QCD at $a^{-1}\simeq 2$ GeV on a $16^3\times 32\times 16$ lattice, and further applying the second method to the clover quark action at a similar lattice spacing and nucleon mass. We obtain good signals from both approaches. In particular the second method works well with both fermion formulations.

description: Observed extinction curves of active galactic nuclei (AGNs) are significantly different from those observed in the Milky Way. The observations require preferential removal of small grains at the AGN environment; however, the physics for this remains unclear. In this paper, we propose that dust destruction by charging, or Coulomb explosion, may be responsible for AGN extinction curves. Harsh AGN radiation makes a dust grain highly charged through photoelectric emission, and grain fission via the Coulomb explosion occurs when the electrostatic tensile stress of a charge grain exceeds its tensile strength. We show that the Coulomb explosion can preferentially remove both small silicate and graphite grains and successfully reproduce both flat extinction curves and the absence of 2175Å~bump.

We show that the response function distinguishes between the local and global (Minkowski) inertial frames and picks up the presence of the shell even when the detector is switched on for a finite time interval within which a light signal cannot travel to the shell and back as required by a classical measurement. We also analyze how the response of the detector depends on its location within the shell.

description: This paper proves the existence and uniqueness of Cournot equilibrium in models of international trade under oligopoly. The existence of Cournot equilibrium is established without the usual assumption that profit functions are concave. Instead the proof uses a weaker "aggregate concavity" condition. A simple proof is used to establish the uniqueness of the equilibrium. And, the paper considers the implications of the assumptions, used to prove the existence and uniqueness of the equilibrium, on the comparative static results.

description: The dynamical response of an atomic Bose-Einstein condensate manipulated by an integrated atom optics device such as a microtrap or a microfabricated waveguide is studied. We show that when the miniaturization of the device enforces a sufficiently high condensate density, three-body interactions lead to a spatial modulational instability that results in a fundamental limit on the coherent manipulation of Bose-Einstein condensates.

Export Subsidies and Countervailing Tariffs

Subjects: Financial Economics

description: This paper analyses how retaliation affects the profit shifting argument for export subsidies. Trade policy is modelled as a multistage game. At the first stage the foreign country sets its export subsidy, and then at the second stage the domestic country sets its tariff and/or production subsidy. If the domestic country pursues an optimal trade policy then it will always gain from a foreign export subsidy. When the domestic country uses a tariff and a production subsidy, the optimal foreign policy is an export subsidy. If the domestic country only uses a tariff then an export tax is usually the optimal foreign policy.
REASSESSING PRODUCER BEHAVIOUR IN A POLICY MODIFIED PRODUCTION ENVIRONMENT

Subjects: Demand and Price Analysis

description: This paper presents a new approach to assessing the impact of price support policies on producer behaviour. This approach takes explicit account of the impact of such policies on a producer's uncertain production environment and includes a numerical procedure for calculating ex ante price variability from ex post producer price data. The methodology is applied to European agricultural industries in which intervention purchasing schemes operate. Results show that price support policies can so severely distort the signal producers receive from world markets that their supply response is the opposite of that which would occur in the absence of the policy.
title: Post Privatisation Operating and Financial Performance of Newly Privatised Firms: Evidence From Pakistan
Creators: name: Ahmad, Sardar
Publisher: name: The Open University
Year: 2010

description: This study investigates post privatisation operating and financial performance of newly privatised firms in Pakistan. The sample consists of fifteen firms privatised in the period 2002 - 2008. Operating performance of newly privatised firms in this study is measured over a four year period including the year of privatisation. The three years trend of post privatisation operating performance is compared to operating performance in the year of privatisation. Financial performance is measured using buy-and-hold abnormal returns (BHAR). Results of the study show that post privatisation, profitability, efficiency and pay out increases, while leverage decreases for more than 50% of the sample firms. The results also indicate that firms privatised through different methods of privatisation show different trends in post privatisation operating performance. Findings regarding the post privatisation financial performance show that BHAR are negative for all of the sample firms over the three years horizon, while different methods used to privatise state owned enterprises (SOEs) does not affect post privatisation BHARs of newly privatised firms.
THE INTERTEMPORAL DEMAND FOR CONSUMER TECHNOLOGIES REQUIRING JOINT HARDWARE AND SOFTWARE INPUTS

description: In this paper we explore the demand for consumer technologies that involve joint inputs in the generation of the service flow. An intertemporal model is used in the analysis. The impact of hardware and software prices on hardware and software demand as well as the impact of changes in the size of the software catalogue are analysed. The model allows copying and it is shown that the ease of copying has a significant impact on hardware and software demands and that the presence of copying has a significant impact on the reactions of hardware and software purchases to changes in the size of the software catalogue and its intertemporal availability. The role of copying in the competition between technologies is also addressed, and it is shown that the prospect of a copying facility on a forthcoming technology will tend to reduce the demand for a current technology without such a facility and moreover will reduce the demand for software for that technology.

description: In this paper existing epidemic models of diffusion in the literature are modified to give freer interaction between exogenous and endogenous factors in the diffusion process and to also reflect the role of economic factors in that process. A new encompassing model is proposed and its properties explored. The model is applied to the diffusion of colour television ownership in the UK and outperforms the existing models in the literature. The exogenous factors play a dominant role in the diffusion of colour television in the UK.

Extended thermodynamics and microstructures of four-dimensional charged Gauss-Bonnet black hole in AdS space

description: The discovery of new four-dimensional black hole solutions presents a new approach to understand the Gauss-Bonnet gravity in low dimensions. In this paper, we test the Gauss-Bonnet gravity by studying the phase transition and microstructures for the four-dimensional charged AdS black hole. In the extended phase space, where the cosmological constant and the Gauss-Bonnet coupling parameter are treated as thermodynamic variables, we find that the thermodynamic first law and the corresponding Smarr formula are satisfied. Both in the canonical ensemble and grand canonical ensemble, we observe the small-large black hole phase transition, which is similar to the case of the van der Walls fluid. This phase transition can also appear in the neutral black hole system. Furthermore, we construct the Ruppeiner geometry, and find that besides the attractive interaction, the repulsive interaction can also dominate among the microstructures for the small black hole with high temperature in a charged or neutral black hole system. This is quite different from the five-dimensional neutral black hole, for which only dominant attractive interaction can be found. The critical behaviors of the normalized scalar curvature are also examined. These results will shed new light into the characteristic property of four-dimensional Gauss-Bonnet gravity.

description: A simplified version of an analysis by Mayshar (1977) is established in order to expose and explain the key factor behind the case for subsidizing private risky investment. A critical evaluation of the analysis motivates an extension of the model to incorporate moral hazard. It is demonstrated that the main conclusion of the former analysis carries over to the revised model under reasonable assumptions.

Pulsar kicks from a dark-matter sterile neutrino

description: We show that a sterile neutrino with mass in the 1-20 keV range and a small mixing with the electron neutrino can simultaneously explain the origin of the pulsar motions and the dark matter in the universe. An asymmetric neutrino emission from a hot nascent neutron star can be the explanation of the observed pulsar velocities. In addition to the pulsar kick mechanism based on resonant neutrino transitions, we point out a new possibility: an asymmetric off-resonant emission of sterile neutrinos. The two cases correspond to different values of the masses and mixing angles. In both cases we identify the ranges of parameters consistent with the pulsar kick, as well as cosmological constraints.
