description: Mongolia's extensive mineral deposits and attendant growth in mining-sector activities have transformed Mongolia's economy, which traditionally has been dependent on herding and agriculture. In this paper a Keynesian type equilibrium displacement model is developed to deduce hypotheses about the effects of mining on agriculture. A major hypothesis to be tested is whether the effects have been adverse, as suggested by the "Dutch Disease" hypothesis.

description: Next year will mark the 90th anniversary of the great influenza pandemic of 1918, an event widely considered to be one of the greatest natural disasters in human history. Historians estimate that ≥50 million people died worldwide, including >450,000 documented deaths in the United States alone (1). Since then, the 20th century witnessed two more influenza pandemics, although fortunately none comparable in ferocity to the 1918 pandemic (2). Pandemics—epidemics so large that virtually the entire world is affected—have occurred several times in each of the last several centuries. Most virologists therefore believe that it is inevitable that we will experience at least one pandemic in this century, and very likely more. However, if a pandemic were to strike in the near future, it is likely that vaccine would not be available for at least 4-6 months (3). Antivirals, if effective against the pandemic strain, would probably also be in short supply. Few of these measures can be applied at pandemic scale, in which half the population of the world would likely be infected over the course of a year or more. We would be left with other measures, now termed "nonpharmaceutical interventions," to stave off the worst effects of a pandemic until a vaccine could be produced and widely administered (4, 5). Because many of these interventions, such as closing schools or shutting down mass transit, could be very disruptive to society, it is important to use effective measures in a rational way. But which measures are most effective, and how should they be applied? Do any nonpharmaceutical interventions actually help? Until now, there has been very little systematic examination of these questions.

description: An inhomogeneous (1+1)-dimensional model of the quantum gravity is considered. It is found, that this model corresponds to a string propagating against some curved background space. The quantization scheme including the Wheeler-DeWitt equation and the "particle on a sphere" type of the gauge condition is suggested. In the quantization scheme considered, the "problem of time" is solved by building of the quasi-Heisenberg operators acting in a space of solutions of the Wheeler-DeWitt equation and the normalization of the wave function corresponds to the Klein-Gordon type. To analyze the physical consequences of the scheme, a (1+1)-dimensional background space is considered for which a classical solution is found and quantized. The obtained estimations show the way to solution of the cosmological constant problem, which consists in compensation of the zero-point oscillations of the matter fields by the quantum oscillations of the scale factor. Along with such a compensation, a slow global evolution of a background corresponding to an universe expansion exists.

Prices and Incentives: Towards a General Theory of Compensation and Competition

name: Nalebuff, Barry J.
Publisher: name: Columbia University
Year: 1983
Subjects: Economics

description: This article analyzes the role of competitive compensation schemes (in which pay depends on relative performance) in economies with imperfect information. These compensation schemes have desirable risk, incentive, and flexibility properties; they provide for an automatic adjustment of rewards and incentives in response to common changes in the environment. When environmental uncertainty is large, such schemes are shown to be preferable to individualistic reward structures; in the limit, as the number of contestants becomes large, expected utility may approach the first-best (perfect information) level. We study the design of contests, including the optimal use of prizes versus punishments and absolute versus relative performance standards. The analysis can also be viewed as a contribution to the multiagent, single-principal problem.

Labor Turnover, Wage Structure and Moral Hazard: The Inefficiency of Competitive Markets
Creators: name: Stiglitz, Joseph E.
name: Arnott, Richard J.
Publisher: name: Columbia University
Year: 1985
Subjects: Economics
Labor economics

description: A multiperiod, general equilibrium model of the labor market is developed in which risk-averse workers are faced with job-related uncertainty and labor turnover is costly. If a worker is unlucky and suffers a bad job match, he quits and joins another firm, hoping that he will like its work environment more. Because the quality of a job match is unobservable, workers cannot insure against the risk of a bad match. The firm provides implicit insurance against job dissatisfaction, typically by paying workers more than their net marginal products in their early years with the firm and less subsequently. Since the probabilities of the insured-against events (the quit rates over time) are affected by the amount of such insurance provided, this implicit insurance is characterized by moral hazard. Individuals quit when in the absence of insurance they would not. The equilibrium contract balances out efficiency in risk bearing with efficiency in turnover incentives. We show that the equilibrium contract is not (constrained) efficient and indicate why.

description: After 70 years of communist regime, Mongolia chose a radical transition for democracy and a market economy in 1990. Since the 2000s, the Mongolian government has been promoting the mining industry to increase its foreign exchanges. The mining sector may offer local job opportunities and revenues, but might also cause loss and degradation of pasture land the local people depend on. An empirical study is conducted to investigate whether the immigration of rural people from a mining area is different from that of a non-mining area using a probit model based on a 2013 workforce survey of Mongolia. The result shows that mining soums receive fewer outsiders than the non-mining soums, suggesting local mining activities exert limited economic linkage in local community for a case of Mongolia.
New generation of double beta decay experiments: are there any limitations?

description: New generation experiments on search for neutrinoless double beta decay with sensitivity to effective Majorana neutrino mass on the level $\sim$ 3-5 meV is discussed. Possible restrictions at achievement of this purpose (possibility to produce big amount of enriched isotopes, possibility to reach very low background level, energy resolution and possible cost of experiments) are considered. It is shown that for realization of so ambitious project 10 tons (or more) of enriched isotope is required. Background index should be on the level $\le$ 10$^{-5}-10^{-6}$ c/kg$\cdot$ keV$\cdot$ y. Besides, the energy resolution of the detector should be not worse than 1-2%. It is shown that $^{130}$TeO$_2$ low temperature bolometer looks as the most realistic candidate for such experiments. Under some conditions experiments with $^{76}$Ge, $^{100}$Mo and $^{136}$Xe can be realized too.

description: Isocurvature perturbations naturally occur in models of inflation consisting of more than one scalar field. In this paper we calculate the spectrum of isocurvature perturbations generated at the end of inflation for three different inflationary models consisting of two canonical scalar fields. The amount of non-adiabatic pressure present at the end of inflation can have observational consequences through the generation of vorticity and subsequently the sourcing of B-mode polarisation. We compare two different definitions of isocurvature perturbations and show how these quantities evolve in different ways during inflation. Our results are calculated using the open source Pyflation numerical package which is available to download.

description: The nonequilibrium dynamics of carriers and phonons in graphene is investigated by solving the microscopic kinetic equations with the carrier-phonon and carrier-carrier Coulomb scatterings explicitly included. The Fermi distribution of hot carriers are found to be established within 100 fs and the temperatures of electrons in the conduction and valence bands are very close to each other, even when the excitation density and the equilibrium density are comparable, thanks to the strong inter-band Coulomb scattering. Moreover, the temporal evolutions of the differential transmission obtained from our calculations agree with the experiments by Wang et al. [Appl. Phys. Lett. 96, 081917 (2010)] and Hale et al. [Phys. Rev. B 83, 121404 (2011)] very well, with two distinct differential transmission relaxations presented. We show that the fast relaxation is due to the rapid carrier-phonon thermalization and the slow one is mainly because of the slow decay of hot phonons. In addition, it is found that the temperatures of the hot phonons in different branches are different and the temperature of hot carriers can be even lower than that of the hottest phonons. Finally, we show that the slow relaxation rate exhibits a mild valley in the excitation density dependence and is linearly dependent on the probe-photon energy.

Sensitivity analysis of simple global marine biogeochemical models
Creators: name: Kriest, Iris
name: Oschlies, Andreas

Publisher: name: Columbia University
Year: 2012
Subjects: Biogeochemistry

description: This study presents results from 46 sensitivity experiments carried out with three structurally simple (2, 3, and 6 biogeochemical state variables, respectively) models of production, export and remineralization of organic phosphorus, coupled to a global ocean circulation model and integrated for 3000 years each. The models' skill is assessed via different misfit functions with respect to the observed global distributions of phosphate and oxygen. Across the different models, the global root-mean square misfit with respect to observed phosphate and oxygen distributions is found to be particularly sensitive to changes in the remineralization length scale, and also to changes in simulated primary production. For this metric, changes in the production and decay of dissolved organic phosphorus as well as in zooplankton parameters are of lesser importance. For a misfit function accounting for the misfit of upper-ocean tracers, however, production parameters and organic phosphorus dynamics play a larger role. Regional misfit patterns are investigated as indicators of potential model deficiencies, such as missing iron limitation, or deficiencies in the sinking and remineralization length scales. In particular, the gradient between phosphate concentrations in the northern North Pacific and the northern North Atlantic is controlled predominantly by the biogeochemical model parameters related to particle flux. For the combined 46 sensitivity experiments performed here, the global misfit to observed oxygen and phosphate distributions shows no clear relation to either simulated global primary or export production for either misfit metric employed. However, a relatively tight relationship that is very similar for the different model of different structural complexity is found between the model-data misfit in oxygen and phosphate distributions to simulated meso- and bathypelagic particle flux. Best agreement with the observed tracer distributions is obtained for simulated particle fluxes that agree most closely with sediment trap data for a nominal depth of about 1000 m, or deeper.

description: Objective: To empirically describe the integration of pediatric disaster services into regional systems of care after the April 27, 2011, tornado in Tuscaloosa, Alabama, a community with no pediatric emergency department or pediatric intensive care unit and few pediatric subspecialists. Study design: Data were obtained in interviews with key informants including professional staff and managers from public health and emergency management agencies, prehospital emergency medical services, fire departments, hospital nurses, physicians, and the trauma program coordinator. Results: A single hospital in Tuscaloosa served 800 patients on the night of the tornado. More than 100 of these patients were children, including more than 20 with critical injuries. Many children were unaccompanied and unidentified on arrival. Resuscitation and stabilization were performed by nonpediatric prehospital and emergency department staff. More than 20 children were secondarily transported to the nearest children's hospital an hour's drive away under the care of nonpediatric local emergency medical services providers. No preventable adverse events were identified in the resuscitation and secondary transport phases of care. Stockpiled supplies and equipment were adequate to serve the needs of the disaster victims, including the children. Conclusion: Essential aspects of preparation include pediatric-specific clinical skills, supplies and equipment, operational disaster plans, and interagency practice embedded in everyday work. Opportunities for improvement identified include more timely response to warnings, improved practices for identifying unaccompanied children, and enhanced child safety in shelters. Successful responses depended on integration of pediatric services into regional systems of care.
Defining math disability : the impact of using different cut offs when assessing the cognitive characteristics of math disabled participants
Creators: name: Pinkerton, Neil A.
Publisher: name: University of British Columbia
Year: 2011

description: Mathematics disabilities (MD) can cause serious difficulties for children throughout their education. However, there is a lack of consensus in the literature regarding how MD should be defined. This makes it difficult to compare results across studies and to determine the overall cognitive profile of MD. The present study investigated the cognitive profiles of participants with MD defined using various cut off criteria and using different assessment measures. Further, this study endeavoured to investigate the differences between those who have MD at one time point and those who have MD at two time points (MD persistent). Over 700 participants were recruited from the North Vancouver school district to participate in this study. Participants were evaluated over two years (grades 2 and 3). Performance was measured using 16 different cognitive measures and 4 achievement tests. Scores on the achievement tests were used to assign MD status. A series of t-tests were conducted to determine whether there are differences between the cognitive profiles of those defined as MD using a 10th percentile cut off (MD10), a 25th percentile cut off (MD25), and a low achieving score between the 11th and 25th percentiles MD(11-25) when compared to typically achieving students (TA). Cut offs were based on performance on two separate math achievement tests: the Woodcock-Johnson Third Edition (WJ III) Calculation test and the Woodcock-Johnson Third Edition Applied Problems test. This study concludes that MD10, MD25, and MD(11-25) all represent similar enough cognitive profiles when compared to the TA group that using a 25% cut off to define MD will suffice for future research. Furthermore, the results suggest that the MD persistent group has a similar enough profile to the terminus point group that additional caution should be used when studying MD persistent in the future. The cognitive profiles of the MD groups are described and implications for research and practice are discussed.

description: We study the classical solutions of three dimensional topologically massive gravity (TMG) and its higher spin generalization, in the first order formulation. The action of higher spin TMG has been proposed in arXiv:1110.5113 to be of a Chern-Simons-like form. The equations of motion are more complicated than the ones in pure higher spin AdS$_3$ gravity, but are still tractable. As all the solutions in higher spin gravity are automatically the solutions of higher spin TMG, we focus on other solutions. We manage to find the AdS pp-wave solutions with higher spin hair, and find that the nonvanishing higher spin fields may or may not modify the pp-wave geometry. In order to discuss the warped spacetime, we introduce the notion of special Killing vector, which is defined to be the symmetry on the frame-like fields. We reproduce various warped spacetimes of TMG in our framework, with the help of special Killing vectors.

The equations involve an SU(2) gauge field and some auxiliary fields in addition to the metric. Four-dimensional ellipsoids with U(1)xU(1) isometry are shown to admit a supersymmetry if these additional fields are chosen appropriately. We compute the partition function of general Seiberg-Witten theories on ellipsoids, and the result suggests a correspondence with 2D Liouville or Toda correlators with general coupling constant b.

description: This paper undertakes three sets of tasks: (i) it analyzes positive and normative aspects of price scissors (the domestic terms of trade between agriculture and industry) within nonsocialist as well as socialist LDCs. The critical role of the economy's institutional features (e.g., external trade environment, wage and income determination, and wage-productivity effects) is emphasized. Certain aspects of the Soviet Industrialization Debate and subsequent collectivization are interpreted, (ii) It develops simple rules to delineate who gains and who loses (within agriculture) from changes in terms of trade, (iii) It presents powerful (and informationally parsimonious) rules for Pareto-improving price reforms for cash crops and agricultural inputs.
Effect of peer tutoring in reading for boys in French immersion
Creators: name: Hodson, Helen
Publisher: name: University of British Columbia
Year: 2012

description: Inspired by concern for the low motivation for reading in French of boys in French immersion programs, a study was undertaken in an elementary school in Vancouver, British Columbia, in the form of a reading intervention program. The program consisted of a peer tutoring reading group for French immersion males where the tutors were Grade 7 boys and the tutees were Grade 5 boys. The program was based on the Peer Tutoring Literacy Program™ for French Immersion Schools, which was used successfully in Elementary schools in Vancouver. Students met with their partners every week and read together French texts that were especially selected for boys. In addition to increasing motivation for reading, a number of other outcomes were examined: Whether the program would encourage more home reading in French, whether the program would increase the confidence of the tutees, the effect of the gender of the tutors and any effects that the tutoring program had on the Grade 7 tutors. Data were collected in the form of questionnaires (pre-and post-program), and interviews. The results suggest that, overall, motivation for reading in French and confidence in French reading abilities of the tutees increased but that the role of gender was not as significant as anticipated. Effects on the Grade 7 tutors were minimal.

description: Let $T_o(k)$ denote the number of solutions of $\sum_{i=1}^k\frac 1{x_i}=1$ in odd numbers $11$ in $S(p_1, p_2,..., p_t)$ is more than 1. In this paper we study $T_o(k)$ and $T_k(p_1,..., p_t)$. Three of our results are: 1) $T_o(2k+1)\ge (\sqrt 2)^{(k+1)(k-4)}$ for all $k\ge 4$; 2) if the inverse sum of all elements $s_j>1$ in $S(p_1, p_2,..., p_t)$ is more than 1, then $T_k(p_1,..., p_t)\not= 0$ for infinitely many $k$ and the set of these $k$ is the union of finitely many arithmetic progressions; 3) there exists two constants $k_0=k_0(p_1,..., p_t)>1$ and $c=c(p_1,..., p_t)>1$ such that for any $k>k_0$ we have either $T_k(p_1,..., p_t)= 0$ or $T_k(p_1,..., p_t)>c^k$.

Competition and the Number of Firms in a Market: Are Duopolies More Competitive Than Atomistic Markets?
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University
Year: 1987
Subjects: Economics

description: This paper uses a variant of the standard search model to examine market equilibrium and the consequences for market equilibrium of an increase in the number of firms. If marginal search costs increase with the number of searches, then the demand curve facing any firm will be kinked, with the elasticity of demand with respect to price decreases being less than with respect to price increases; prices may not change in response to changes in marginal costs. As the number of firms increases, the maximum price that is consistent with equilibrium increases, to the monopoly price, but the minimum price decreases. On the other hand, if marginal search costs decrease with the number of searches, equilibrium, if it exists, is characterized by a price distribution.

Fingerprints of Dirac points in first-principles scanning tunneling spectra of graphene on a metal substrate

description: Graphene physisorbed on a metal has its characteristic Dirac cones preserved in the band-structure, but the Fermi level of the system is shifted due to the interaction with the substrate. Based on density functional calculations with van der Waals corrections, we present a method to determine the position of the Dirac point with respect to the Fermi level from the measured scanning tunneling spectra (STS). It has been demonstrated that the dips in both simulated local density of states and in the observed dI/dV profiles are indeed the fingerprints of the Dirac points. The type and the level of doping can be then inferred directly from the STS data without any additional experimental technique. Test calculations of graphene on a Cu(111) substrate have shown that the predicted position of the Dirac point is in close proximity to the experimental value reported in the recent studies. Moreover, simulations for graphene on a Pt(111) surface allow us to explain the apparent contradictions in the state-of-the-art experimental works.

description: A framework for performing dynamic mesh adaptation with the discontinuous Galerkin method (DGM) is presented. Adaptations include modifications of the local mesh step size (h-adaptation) and the local degree of the approximating polynomials (p-adaptation) as well as their combination. The computation of the approximation within locally adapted elements is based on projections between finite element spaces (FES), which are shown to preserve an upper limit of the electromagnetic energy. The formulation supports high level hanging nodes and applies precomputation of surface integrals for increasing computational efficiency. Error and smoothness estimates based on interface jumps are presented and applied to the fully hp-adaptive simulation of two examples in one-dimensional space. A full wave simulation of electromagnetic scattering form a radar reflector demonstrates the applicability to large scale problems in three-dimensional space.

Nonlinear photon transport in a semiconductor waveguide-cavity system containing a single quantum dot: Anharmonic cavity-QED regime

description: We present a semiconductor master equation technique to study the input/output characteristics of coherent photon transport in a semiconductor waveguide-cavity system containing a single quantum dot. We use this approach to investigate the effects of photon propagation and anharmonic cavity-QED for various dot-cavity interaction strengths, including weakly-coupled, intermediately-coupled, and strongly-coupled regimes. We demonstrate that for mean photon numbers much less than 0.1, the commonly adopted weak excitation (single quantum) approximation breaks down, even in the weak coupling regime. As a measure of the anharmonic multiphoton-correlations, we compute the Fano factor and the correlation error associated with making a semiclassical approximation. We also explore the role of electron--acoustic-phonon scattering and find that phonon-mediated scattering plays a qualitatively important role on the light propagation characteristics. As an application of the theory, we simulate a conditional phase gate at a phonon bath temperature of $20 $K in the strong coupling regime.

description: Our objective here is to examine how the centralization or decentralization of decision-making authority affects the quality of the managers who are actually selected. This question is naturally dynamic because the quality of current managers is not only influenced by that of past managers, but it, in turn, affects the quality of future managers.
