GROWTH, INEQUALITY AND POVERTY: SOME HARD QUESTIONS
Creators: name: Kanbur, Ravi
name: Kanbur, Ravi
Publisher: name: Unknown
Year: 2004
Subjects: Food Security and Poverty

description: This commentary poses a series of progressively harder questions in the economic analysis of growth, inequality and poverty. Starting with relatively straightforward analysis of the relationship between growth and inequality, the first level of hard questions come when we ask what policies and institutions are causally related to equitable growth. Some progress is being made here by the economics literature, but relatively little is known about the second level, harder questions—how a society comes to acquire “good” policies and institutions, and what exactly it is that we are buying into when we accept the number one Millennium Development Goal of the United Nations— halving the incidence of income poverty by the year 2015.

description: This study investigates the determinants that influence a firm’s decision to use external private equity in agriculture. The use of external equity as a funding source in agriculture has increased since 1990; however, the literature addressing this phenomenon is limited. The asset specificity approach (Williamson 1988) offers insightful contributions to understand the choice of financial mechanisms. Specifically, financial structure is related to asset specificity, the extent to which assets are redeployable to alternative uses, a particularly important attribute in agricultural production. I construct an international dataset of companies that receive external private equity finance to test the determinants of using external equity finance. Results show that the attributes of the assets involved in agriculture are important determinants of financing choices.
Electron-Phonon interaction and electronic decoherence in molecular conductors

description: We perform a brief but critical review of the Landauer picture of transport that clarifies how decoherence appears in this approach. On this basis, we present different models that allow the study of the coherent and decoherent effects of the interaction with the environment in the electronic transport. These models are particularly well suited for the analysis of transport in molecular wires. The effects of decoherence are described through the D'Amato-Pastawski model that is explained in detail. We also consider the formation of polarons in some models for the electron-vibrational interaction. Our quantum coherent framework allows us to study many-body interference effects. Particular emphasis is given to the occurrence of anti-resonances as a result of these interferences. By studying the phase fluctuations in these soluble models we are able to identify inelastic and decoherence effects. A brief description of a general formulation for the consideration of time-dependent transport is also presented.

description: This paper presents a framework for estimating the remaining useful life (RUL) of mechanical systems. The framework consists of a multi-layer perceptron and an evolutionary algorithm for optimizing the data-related parameters. The framework makes use of a strided time window to estimate the RUL for mechanical components. Tuning the data-related parameters can become a very time consuming task. The framework presented here automatically reshapes the data such that the efficiency of the model is increased. Furthermore, the complexity of the model is kept low, e.g. neural networks with few hidden layers and few neurons at each layer. Having simple models has several advantages like short training times and the capacity of being in environments with limited computational resources such as embedded systems. The proposed method is evaluated on the publicly available C-MAPSS dataset, its accuracy is compared against other state-of-the art methods for the same dataset.

description: Longitudinal lepton polarization asymmetry in B_q -> l l (q = d, s$ and l = e, mu, tau) decays is investigated. The analysis is done in a general manner by using the effective operators approach. It is shown that the longitudinal lepton polarization asymmetry would provide a direct search for the scalar and pseudoscalar type interactions, which are induced in all variants of Higgs-doublet models.

This interpretation is based on the direct excitation of charge collective modes, which become nearly critical in the proximity to a charge-ordering instability. The nearly critical character of these excitations entails a peculiar temperature dependence and a pseudo-scaling form of the lineshapes, which are in agreement with the experimental data.

description: Recently in [M. Hairer, M. Hutzenthaler, and A. Jentzen, Ann. Probab. 43, 2 (2015), 468--527] and [A. Jentzen, T. Müller-Gronbach, and L. Yaroslavtseva, Commun. Math. Sci. 14, 6 (2016), 1477--1500] stochastic differential equations (SDEs) with smooth coefficient functions have been constructed which have an arbitrarily slowly converging modulus of continuity in the initial value. In these SDEs it is crucial that some of the first order partial derivatives of the drift coefficient functions grow at least exponentially and, in particular, quicker than any polynomial. However, in applications SDEs do typically have coefficient functions whose first order partial derivatives are polynomially bounded. In this article we study whether arbitrarily bad regularity phenomena in the initial value may also arise in the latter case and we partially answer this question in the negative. More precisely, we show that every additive noise driven SDE which admits a Lyapunov-type condition (which ensures the existence of a unique solution of the SDE) and which has a drift coefficient function whose first order partial derivatives grow at most polynomially is at least logarithmically Hölder continuous in the initial value.

Massless monopole clouds and electric-magnetic duality

Year: 2002
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We discuss the Montonen-Olive electric-magnetic duality for the BPS massless monopole clouds in N=4 supersymmetric Yang-Mills theory with non-Abelian unbroken gauge symmetries. We argue that these low energy non-Abelian clouds can be identified as the duals of the infrared bremsstrahlung radiation of the non-Abelian massless particles. After we break the N=4 supersymmetry to N=1 by adding a superpotential, or to N=0 by further adding soft breaking terms, these non-Abelian clouds will generally condense and screen the non-Abelian charges of the massive monopole probes. The effective mass of these dual non-Abelian states is likely to persist as we lower the energy to the QCD scale, if all the non-Abelian Higgs particles are massive. This can be regarded as a manifestation of the non-Abelian dual Meissner effect above the QCD scale, and we expect it to continuously connect with the confinement as we lower the supersymmetry breaking scale to the QCD scale.

description: Background: Polymorphisms in T-cell immunoglobulin and mucin domain 3 (TIM-3) gene have been implicated in susceptibility to autoimmune diseases (ADs) with inconsistent results. The aim of this study was to perform meta-analyses for clarifying the relationship between them. Methods: All relevant case-control studies were searched in PubMed, Embase, Wanfang, and China National Knowledge Infrastructure. Meta-analysis was conducted in the dominant and allelic models, and checked for heterogeneity and publication bias. The Odds ratio (OR) and 95% confidence interval (CI) was used to assess the strength of the associations. Results: Seventeen studies with four TIM-3 polymorphisms (+4259A>C, −574G>T, −1516G>T, and −1541C>T) were identified, involving 3,399 cases and 3,911 controls. TIM-3 −1516G>T polymorphism showed significant associations with ADs risk among Chinese; however, the significant finding was unstable in sensitivity analysis. In the overall population, TIM-3 + 4259A>C polymorphism demonstrated stable significant associations with ADs risk in the dominant (OR = 1.57, 95%CI = 1.13–2.18, P = 0.007) and allelic (OR = 1.51, 95%CI = 1.10–2.08, P = 0.01) models, and with rheumatoid arthritis (RA) risk in the dominant (OR = 2.09, 95%CI = 1.60–2.73, P < 0.00001) and allelic (OR = 1.95, 95%CI = 1.51–2.51, P < 0.00001) models. Cumulative meta-analyses confirmed that these significant results were robust. Concerning TIM-3 −574 G > T or −1541C>T polymorphism, no significant associations were detected. Conclusion: These findings reveal that TIM-3 + 4259A>C might be a potential susceptible predictor of ADs and especially RA. Further functional and clinical investigation between these diseases and TIM-3 polymorphisms is warranted.

In arXiv:1411.5011 we proved that if $\mathbb{K}$ is the field of complex or real numbers, then the set $S_f$ of points at which $f$ is not proper, is covered by polynomial curves of degree at most $d-1$. In this paper we generalize this result to positive characteristic. We provide a geometric proof of an upper bound by $d$.

Year: 2001
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The fluctuation induced diamagnetism of underdoped high temperature superconductors is studied in the framework of the Lawrence-Doniach model. By taking into account the fluctuations of the phase of the order parameter only, the latter reduces to a layered XY-model describing a liquid of vortices which can be either thermally excited or induced by the external magnetic field. The diamagnetic response is given by a current-current correlation function which is evaluated using the Coulomb gas analogy. Our results are then applied to recent measurements of fluctuation diamagnetism in underdoped YBCO. They allow to understand both the observed anomalous temperature dependence of the zero-field susceptibility and the two distinct regimes appearing in the magnetic field dependence of the magnetization.

description: We consider an optical resonator containing a photonic crystal fiber and driven coherently by an injected beam. This device is described by a generalized Lugiato--Lefever equation with fourth order dispersion We use an asymptotic approach to derive interaction equations governing the slow time evolution of the coordinates of two interacting dissipative solitons. We show that Cherenkov radiation induced by positive fourth-order dispersion leads to a strong increase of the interaction force between the solitons. As a consequence, large number of equidistant soliton bound states in the phase space of the interaction equations can be stabilized. We show that the presence of even small spectral filtering not only dampens the Cherenkov radiation at the soliton tails and reduces the interaction strength, but can also affect the bound state stability.

description: Nowadays society is more and more dependent on critical infrastructures. Critical network infrastructures (CNI) are communication networks whose disruption can create a severe impact. In this paper we propose REACT, a distributed framework for reactive network resilience, which allows networks to reconfigure themselves in the event of a security incidents so that the risk of further damage is mitigated. Our framework takes advantage of a risk model based on multilayer networks, as well as a graph-coloring problem conversion, to identify new, more resilient configurations for networks in the event of an attack. We propose two different solution approaches, and evaluate them from two different perspectives, with a number of centralized optimization techniques. Experiments show that our approaches outperform the reference approaches in terms of risk mitigation and performance.

description: This study reviews the ongoing reforms of national agricultural research systems (NARS) in sub-Saharan Africa. The study not only takes stock of the principal reform themes (i.e., a redefinition of the role of government, decentralization, stakeholder participation, new financing mechanisms, and system linkages), but also highlights the underlying ideas and concepts that shape the present NARS reform agenda. NARS reform details are illustrated and discussed in seven case-study countries: Côte d'Ivoire, Ethiopia, Ghana, Kenya, Senegal, Tanzania, and Uganda. While there is considerable consensus about the main trends, there are major differences and disputes on specific aspects of the reform agenda. Moreover, NARS reforms alone will not close the technological divide between Africa and the rest of the world—they are to be seen as part of a far broader modernization agenda.

description: An effective way for a Mobile network operator (MNO) to improve its revenue is price discrimination, i.e., providing different combinations of data caps and subscription fees. Rollover data plan (allowing the unused data in the current month to be used in the next month) is an innovative data mechanism with time flexibility. In this paper, we study the MNO's optimal multi-cap data plans with time flexibility in a realistic asymmetric information scenario. Specifically, users are associated with multi-dimensional private information, and the MNO designs a contract (with different data caps and subscription fees) to induce users to truthfully reveal their private information. This problem is quite challenging due to the multi-dimensional private information. We address the challenge in two aspects. First, we find that a feasible contract (satisfying incentive compatibility and individual rationality) should allocate the data caps according to users' willingness-to-pay (captured by the slopes of users' indifference curves). Second, for the non-convex data cap allocation problem, we propose a Dynamic Quota Allocation Algorithm, which has a low complexity and guarantees the global optimality. Numerical results show that the time-flexible data mechanisms increase both the MNO's profit (25% on average) and users' payoffs (8.2% on average) under price discrimination.

description: Evidence has increasingly mounted in recent decades that outflows of matter and energy from the central parsecs of our Galaxy have shaped the observed structure of the Milky Way on a variety of larger scales. On scales of ~15 pc, the Galactic centre has bipolar lobes that can be seen in both X-rays and radio, indicating broadly collimated outflows from the centre, directed perpendicular to the Galactic plane. On far larger scales approaching the size of the Galaxy itself, gamma-ray observations have identified the so-called Fermi Bubble features, implying that our Galactic centre has, or has recently had, a period of active energy release leading to a production of relativistic particles that now populate huge cavities on both sides of the Galactic plane. The X-ray maps from the ROSAT all-sky survey show that the edges of these cavities close to the Galactic plane are bright in X-rays. At intermediate scales (~150 pc), radio astronomers have found the Galactic Centre Lobe, an apparent bubble of emission seen only at positive Galactic latitudes, but again indicative of energy injection from near the Galactic centre. Here we report the discovery of prominent X-ray structures on these intermediate (hundred-parsec) scales above and below the plane, which appear to connect the Galactic centre region to the Fermi bubbles. We propose that these newly-discovered structures, which we term the Galactic Centre Chimneys, constitute a channel through which energy and mass, injected by a quasi-continuous train of episodic events at the Galactic centre, are transported from the central parsecs to the base of the Fermi bubbles.

description: One often heard counter to the concern on rising income and wealth inequality is that it is wrong to focus on inequality of outcomes in a “snapshot.” Intergenerational mobility and “equality of opportunity”, so the argument goes, is what matters for normative evaluation. In response to this counter, we ask what pattern of intergenerational mobility leads to lower inequality not between individuals but between the dynasties to which they belong? And how does this pattern in turn relate to commonly held views on what constitutes equality of opportunity? We revive and revisit here our earlier contributions which were in the form of working papers (Kanbur and Stiglitz (1982, 1986) in order to engage with the current debate. Focusing on bistochastic transition matrices in order to hold constant the steady state snapshot income distribution, we develop an explicit partial ordering which ranks matrices on the criterion of inequality between infinitely lived dynasties. A general interpretation of our result is that when comparing two transition matrices, if one matrix is “further away” from the identity matrix then it will lead to lower dynastic inequality. More specifically, the result presents a computational procedure to check if one matrix dominates another on dynastic inequality. We can also assess “equality of opportunity”, defined as identical prospects irrespective of starting position. We find that this is not necessarily the mobility pattern which minimizes dynastic inequality.

description: Recently, the development of chiral perturbation theory has allowed the generation of rigorous low energy theorems for various hadronic processes based only on the chiral invariance of the underlying QCD Lagrangian. Such techniques are highly developed and well tested in the domain of pionic and kaonic reactions. In this note we point out that with the addition of a few additional and reasonable assumptions similar predictive power is available for processes involving the eta meson.

description: Los mayas de Yucatán sabían que los cenotes eran la fuente primordial de agua y de vida en la Península y por ello los transformaron en la razón y el centro de los asentamientos,hecho que se evidencia claramente por la gran proliferación de la raíz “dzonot” (cenote) en numerosos topónimos mayas como sucede con“Chikindzonot”, por ejemplo, que significa agua del oeste . Pero los cenotes fueron igualmente importantes para el aspecto ritual y simbólico de los mayas y por ello devinieron, no sólo en notables elementos de la geografía sagrada, sino también en espacios mágicos para el desarrollo de ritos y ceremonias vinculadas con la lluvia,la fertilidad, la vida, la muerte y el renacimiento.

description: Magnet-superconductor hybrid heterostructures constitute a promising candidate system for the quantum engineering of chiral topological superconductivity. Here, we investigate the stability of their topological phases in the presence of various types of potential and magnetic disorder. In particular we consider magnetic disorder in the coupling strength and spin-orientation, as well as percolation type disorder representing missing magnetic moments. We show that potential disorder leads to the weakest suppression of topological phases, while percolation disorder leads to their strongest suppression. In addition, we demonstrate that in the case of correlated potential disorder, the spatial structure of the disorder potential is correlated not only with the particle number density, but also the Chern number density. Finally, we demonstrate how the disorder-induced destruction of topological superconductivity is reflected in the spatial structure and distribution of the Chern number density.

description: We present a new approach to identify fragments in computer simulations of relativistic heavy ion collisions. It is based on the simulated annealing technique and can be applied to n-body transport models like the Quantum Molecular Dynamics. This new approach is able to predict isotope yields as well as hyper-nucleus production. In order to illustrate its predicting power, we confront this new method with experimental data and show the sensitivity on the parameters which govern the cluster formation.

description: We formulate a dynamical fluctuation theory for stationary non equilibrium states (SNS) which is tested explicitly in stochastic models of interacting particles. In our theory a crucial role is played by the time reversed dynamics. Within this theory we derive the following results: the modification of the Onsager-Machlup theory in the SNS; a general Hamilton-Jacobi equation for the macroscopic entropy; a non equilibrium, non linear fluctuation dissipation relation valid for a wide class of systems; an H theorem for the entropy. We discuss in detail two models of stochastic boundary driven lattice gases: the zero range and the simple exclusion processes. In the first model the invariant measure is explicitly known and we verify the predictions of the general theory. For the one dimensional simple exclusion process, as recently shown by Derrida, Lebowitz, and Speer, it is possible to express the macroscopic entropy in terms of the solution of a non linear ordinary differential equation; by using the Hamilton-Jacobi equation, we obtain an logically independent derivation of this result.

EDUCATION FOR CLIMATE JUSTICE

description: Climate justice requires sharing the burdens and benefits of climate change and its resolution equitably and fairly. It brings together justice between generations and justice within generations. In particular it requires that attempts to address injustice between generations through curbing greenhouse gas emissions do not end up creating injustice in our time by hurting the presently poor and vulnerable. This essay considers the transformative power of education in its many dimensions as one entry point into expanding the scope of policy instruments for climate justice. First, education can change behavior, primarily in rich countries but also in poor countries, and thus help mitigate climate injustice between the generations. Second, resources targeted to the education of the poorest in poor countries can help their development but also help to counter some of the negative spillover effects of interventions to mitigate climate change. Hence the title of this essay — Education for Climate Justice.
Transverse excitations and zigzag transition in quasi-1D hard-disk system

description: Molecular dynamics computer simulations of collective excitations in a system of hard disks confined to a narrow channel of the specific width, that resembles 2D triangular lattice at disk close packing, are performed. We found that transverse excitations, which for hard-disk system are absent in the limit of 1D and are of acoustic nature in the limit of 2D, in the case of q1D hard-disk system emerge in the form of transverse optical excitations and could be considered as a tool to detect the structural transition to a zigzag ordering. By analyzing density evolution of longitudinal static structure factor and pair distribution function we have shown that driving force of zigzag ordering is caging phenomenon that in the case of hard-disk system is governed by excluded volume interaction with first and second neighbors and is of entropic origin.

Perturbation Foundation of q-Deformed Dynamics

description: In the q-deformed theory the perturbation approach can be expressed in terms of two pairs of undeformed position and momentum operators. There are two configuration spaces. Correspondingly there are two q-perturbation Hamiltonians, one originates from the perturbation expansion of the potential in one configuration space, the other one originates from the perturbation expansion of the kinetic energy in another configuration space. In order to establish a general foundation of the q-perturbation theory, two perturbation equivalence theorems are proved: (I) Equivalence theorem {\it I}: Perturbation expressions of the q-deformed uncertainty relations calculated by two pairs of undeformed operators are the same, and the two q-deformed uncertainty relations undercut Heisenberg's minimal one in the same style. (II) The general equivalence theorem {\it II}: for {\it any} potential (regular or singular) the expectation values of two q-perturbation Hamiltonians in the eigenstates of the undeformed Hamiltonian are equivalent to all orders of the perturbation expansion. As an example of singular potentials the perturbation energy spectra of the q-deformed Coulomb potential are studied.

Phase of bi-particle localized states for the Cooper problem in two-dimensional disordered systems

description: The Cooper problem is studied numerically for the Anderson model with disorder in two-dimensions. It is shown that the attractive Hubbard interaction creates a phase of bi-particle localized states in the regime where non-interacting states are delocalized. This phase cannot be obtained in the mean-field approximation and the pair coupling energy is strongly enhanced in this regime. The effects of magnetic field are studied and it is shown that under certain conditions they lead to delocalization.

description: The presence of food waste, and ways to reduce food waste, has generated significant debate among industry stakeholders, policy makers, and consumer groups in the United States and elsewhere. Many have argued that the variety of date labels used by food manufacturers leads to confusion about food quality and food safety among consumers. Here we develop a laboratory experiment with treatments that expose subjects to different date labels (Sell by, Best by, Use by, and Fresh by) for six food products; we include both small and large-sized ready-to-eat cereal, salad greens, and yogurt. Our results show that, holding other observed factors constant, that date labels do influence subjects’ value of food waste. We find that subjects will waste food across all date labels, but that the value of waste is greatest in the “Use by” treatment, the date label suggestive of food safety, and lowest for the “Sell by” treatment. Two-way ANOVA tests provide evidence that subjects respond differentially to date labels by product. Pair-wise comparison indicate that the “Sell by” treatment generates a waste value that is different than other date labels. We see subjects have different values of waste depending on date label and product. The value of waste for cereal is more responsive to “Fresh by”; for salad, the value of waste is more responsive to all date labels except for “Fresh by”; for yogurt, subjects adjusted their value of waste the most to the “Sell by” treatment. Date labels influence food waste despite the limited information provided by the labels.
