description: This article describes sfcross and sfpanel, two new Stata commands for the estimation of cross-sectional and panel-data stochastic frontier models. sfcross extends the capabilities of the frontier command by including additional models (Greene, 2003, Journal of Productivity Analysis 19: 179–190; Wang, 2002, Journal of Productivity Analysis 18: 241–253) and command functionality, such as the possibility of managing complex survey data characteristics. Similarly, sfpanel allows one to fit a much wider range of time-varying inefficiency models compared with the xtfrontier command, including the model of Cornwell, Schmidt, and Sickles (1990, Journal of Econometrics 46: 185–200); the model of Lee and Schmidt (1993, in The Measurement of Productive Efficiency: Techniques and Applications), a production frontier model with flexible temporal variation in technical efficiency; the flexible model of Kumbhakar (1990, Journal of Econometrics 46: 201–211); the inefficiency effects model of Battese and Coelli (1995 Empirical Economics 20: 325–332); and the "true" fixed- and random-effects models of Greene (2005a, Journal of Econometrics 126: 269–303). A brief overview of the stochastic frontier literature, a description of the two commands and their options, and examples using simulated and real data are provided.

description: It is usual in time-to-event data to have more than one event of interest, for example, time to death from different causes. Competing risks models can be applied in these situations where events are considered mutually exclusive absorbing states. That is, we have some initial state—for example, alive with a diagnosis of cancer—and we are interested in several different endpoints, all of which are final. However, the progression of disease will usually consist of one or more intermediary events that may alter the progression to an endpoint. These events are neither initial states nor absorbing states. Here we consider one of the simplest multistate models, the illness-death model. stpm2illd is a postestimation command used after fitting a flexible parametric survival model with stpm2 to estimate the probability of being in each of four states as a function of time. There is also the option to generate confidence intervals and transition hazard functions. The new command is illustrated through a simple example.
Dark Matter freezeout in modified cosmological scenarios

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

description: We study the effects of modifying the expansions history of the Universe on Dark Matter freezeout. We derived a modified Boltzmann equation for freeze-out for an arbitrary energy density in the early Universe and provide an analytic approach using some approximations. We then look at the required thermally averaged cross sections needed to obtain the correct relic density for the specific case where the energy density consists of radiation plus one extra component which cools faster. We compare our analytic approximation to a numerical solutions. We find that it gives reasonable results for most of the parameter space explored, being at most a factor of order one away from the measured value. We find that if the new contribution to the energy density is comparable to the radiation density, then a much smaller cross section for Dark Matter annihilation is required. This would lead to weak scale Dark Matter being much more difficult to detect and opens up the possibility that much heavier Dark Matter could undergo freezeout without violating perturbative unitarity.

Towards foundations for the logic of distinctions
Creators: name: Jablon, Peter
Publisher: name: The Australian National University
Year: 1975

description: This thesis is a contribution to the philosophy of logic and the foundations of metaphysics, and not to logic proper. We suggest how the fundamental concepts of predicate logic and set theory may be reduced entirely, or almost entirely, to relational concepts. We also urge and begin to introduce the use of a new type of interpretation of logic (and we call this type of interpretation a "Chinese-mystical" one). Against this background, we look briefly at a variety of aspects of possible beginnings for the logic of (intensions of) relations (equivalently, for the logic of distinctions). In Chapter 1 we introduce nearly all of the primitive notions and the symbolic vocabulary in terms of which, in Chapter 1 and also later, we attempt to explain all the fundamental concepts of predicate logic and set theory and to explore the logic of contexts and tokenicity. We also remark on some of the differences between our conception of the foundations of logic and the conception presupposed in, or commonly associated with, PM, with special emphasis on the deficiencies of the latter. In Chapter 2 we display various senses in which the properties of the true/false distinction can be said to be generalized to those of certain other distinctions. That is, we suggest that there are certain distinctions any one of which, for the purposes of logic, will effectively achieve all the work the true/false dichotomy can do, and other work besides. And we emphatically suggest that the scope of modern logic should be broadened. In Chapter 3 we attempt to introduce some inchoate aspects of the logic of relations proper (that is, of the intensions of relations). There we also introduce "Chinese-mystical" metaphysics; a "Chinese-mystical" metaphysics can be described as a relational metaphysics which denies any reality to "thing" concepts. In Chapter 4 we explore some of the rudiments of how to attempt to replace the propositional calculus by an analogue which would formalize the logical characteristics of in general unasserted relations instead of those of propositions. In Chapter 5 we briefly explain some of the philosophical inadequacies of contemporary set theory. In Chapter 6 we suggest how set theory can be altered to make it less unacceptable as a formalization of the concept of "manyness" and foundation for mathematics. In Chapter 7 we digress to briefly survey something of the diversity of theories of what are the bearers of truth and falsity. In Chapter 8 we attempt to indulge in a little pioneering work on foundations for the logic of tokenicity. In Chapter 9 we suggest a clearcut way in which the paradoxes of mysticism may be explained logically.

description: We present a directed unloading sand box type avalanche model, driven by slowly lowering the retaining wall at the bottom of the slope. The avalanche propagation in the two dimensional surface is related to the space-time configurations of one dimensional Kardar-Parisi-Zhang (KPZ) type interface growth dynamics. We express the scaling exponents for the avalanche cluster distributions into that framework. The numerical results agree closely with KPZ scaling, but not perfectly.

description: A classic result, originally due to Kluberg-Stern and Zuber, states that operators that vanish by the classical equation of motion (eom) do not mix into "physical" operators. Here we show that and explain why this result does not hold in soft-collinear effective theory (SCET) for the renormalization of power-suppressed operators. We calculate the non-vanishing mixing of eom operators for the simplest case of $N$-jet operators with a single collinear field in every direction. The result implies that---for the computation of the anomalous dimension but not for on-shell matrix elements---there exists a preferred set of fields that must be used to reproduce the infrared singularities of QCD scattering amplitudes. We identify these fields and explain their relation to the gauge-invariant SCET Lagrangian. Further checks reveal another generic property of SCET beyond leading power, which will be relevant to resummation at the next-to-leading logarithmic level, the divergence of convolution integrals with the hard matching coefficients. We propose an operator solution that allows to consistently renormalize such divergences.

On the Influence of Einstein-Podolsky-Rosen Effect on the Domain Wall Formation during the Cosmological Phase Transitions

description: Search for the mechanisms suppressing formation of Higgs field defects (e.g. domain walls) during the cosmological phase transitions is one of key problems in explanation of the observed large-scale uniformity of the space-time. One of the possible solutions can be based on accounting for Einstein-Podolsky-Rosen (EPR) correlations. Namely, if a coherent quantum state of the Higgs field was formed in the course of its previous evolution, then reduction to the state with broken symmetry during the phase transition should be correlated even at the scales exceeding the local cosmological horizons. Detailed consideration of the simplest one-dimensional cosmological model with Z2 Higgs field demonstrates that, at certain parameters of the Lagrangian, EPR-correlations really result in a substantial suppression of spontaneous formation of the domain walls.

Joint state-parameter estimation of a nonlinear stochastic energy balance model from sparse noisy data

description: While nonlinear stochastic partial differential equations arise naturally in spatiotemporal modeling, inference for such systems often faces two major challenges: sparse noisy data and ill-posedness of the inverse problem of parameter estimation. To overcome the challenges, we introduce a strongly regularized posterior by normalizing the likelihood and by imposing physical constraints through priors of the parameters and states. We investigate joint parameter-state estimation by the regularized posterior in a physically motivated nonlinear stochastic energy balance model (SEBM) for paleoclimate reconstruction. The high-dimensional posterior is sampled by a particle Gibbs sampler that combines MCMC with an optimal particle filter exploiting the structure of the SEBM. In tests using either Gaussian or uniform priors based on the physical range of parameters, the regularized posteriors overcome the ill-posedness and lead to samples within physical ranges, quantifying the uncertainty in estimation. Due to the ill-posedness and the regularization, the posterior of parameters presents a relatively large uncertainty, and consequently, the maximum of the posterior, which is the minimizer in a variational approach, can have a large variation. In contrast, the posterior of states generally concentrates near the truth, substantially filtering out observation noise and reducing uncertainty in the unconstrained SEBM.

description: Watersheds are tremendously degraded worldwide, largely in developing countries especially in the Blue Nile Basin in Ethiopia. The degradation is due to several factors including pressure from land use and economic development. The degradation might be characterized by poor water quality, irregularity in water quantity, heavy floods that destroy life and property, sediment deposition in streams and irrigation canals; and sediment deposition on dams etc. Several researchers have suggested different watershed management interventions to end these problems, especially in developing countries. They include reforestation; construction of stone terrace; soil bunds; water harvesting technologies; and crop residue management. However, most landholders are not adopting these recommended technologies mainly due to socio-economic, institutional and policy-related issues. This paper empirically examines existing factors that are perceived to affect landholders’ decisions for adopting improved watershed management intervention technologies in the Blue Nile Basin in Ethiopia. A multi-stage probability sampling techniques was used to sample 300 respondents and a binary Logit model was applied to the data. Results indicate that education, farm size, fertilizer, tropical livestock unit, traditional local institutions, land security and distance to nearest market are found to be significant factors that influence downstream landholders’ decision to adopt improved watershed management technologies.

description: Hawking radiation emanating from two-dimensional charged and uncharged dilatonic black holes - dimensionally reduced from (2+1) spinning and spinless, respectively, BTZ black holes - is viewed as a tunnelling process. Two dimensional dilatonic black holes (AdS(2) included) are treated as dynamical backgrounds in contrast to the standard methodology where the background geometry is fixed when evaluating Hawking radiation. This modification to the geometry gives rise to a nonthermal part in the radiation spectrum. Nonzero temperature of the extremal two-dimensional charged black hole is found. The Bekenstein-Hawking area formula is easily derived for these dynamical geometries.

description: Corner solution responses are frequently observed in the social sciences. One common approach to model phenomena that give rise to corner solution responses is to use the tobit model. If the decision to participate in the market is decoupled from the consumption amount decision, then the tobit model is inappropriate. In these cases, the double-hurdle model presented in Cragg (1971, Econometrica 39: 829–844) is an appropriate alternative to the tobit model. In this article, I introduce a command, dblhurdle, that fits the double-hurdle model. The implementation allows the errors of the participation decision and the amount decision to be correlated. The capabilities of predict after dblhurdle are also discussed.

description: In missing-data analysis, Little’s test (1988, Journal of the American Statistical Association 83: 1198–1202) is useful for testing the assumption of missing completely at random for multivariate, partially observed quantitative data. I introduce the mcartest command, which implements Little’s missing completely at random test and its extension for testing the covariate-dependent missingness. The command also includes an option to perform the likelihood-ratio test with adjustment for unequal variances. I illustrate the use of mcartest through an example and evaluate the finite-sample performance of these tests in simulation studies.

description: Tris(glycinato)Mn(III) and its mixed ligand complexes with azido-, thiocyanato-, chloro- and bromo- groups have been synthesized and characterized by UV–Vis spectrophotometry, IR spectrophotometry, elemental analysis, magnetic susceptibility measurements, thermal analysis, Dart-mass spectrometry, EPR spectral studies, and X-ray powder diffraction studies. The molar extinction coefficient values of the complexes are in the range of spin allowed 5T2g → 5Eg transitions. The magnetic susceptibility measurements of all the complexes confirmed the presence of four unpaired electrons and high spin d4 systems. Room temperature EPR spectrum gives g isotropic value 2.002 indicative of octahedral geometry for the complex. PXRD studies suggest monoclinic system with space group P21/c with a = 9.1382(60) Å, b = 15.5340(11) Å, c = 10.2576(68) Å, and β = 110.598(15)°. The particle size of the complexes lies in the range 26.60–38.79 nm. The tris(glycinato)Mn(III) is an efficient heterogeneous catalyst for decolorization of Xylenol Orange and Methyl Red in the presence of H2O2. It also initiates polymerization of acrylonitrile.
The demand for staple foodstuffs in the Papua New Guinea urban sector
Creators: name: Sackett, M. A
Publisher: name: Canberra, ACT : The Australian National University
Year: 1975
Subjects: subject: Food supply Papua New Guinea

description: Food production in Papua New Guinea has in the past been almost exclusively confined to subsistence production, with the country's modern sector largely dependent upon imported foodstuffs. A rapid increase in urban population and Government desire for a more self-sufficient economy have made domestic food production a matter of the highest priority. In this study, analysis is made of the most comprehensive household expenditure data available to date, with the primary objective of estimating expenditure elasticities for staple foodstuffs. The most notable aspect to emerge is an apparently higher expenditure elasticity for traditional staples than for modern staples such as rice, wheat products and sugar. Examination is also made of the effect of the different price relativities between traditional and modern staples at the various urban centres. Utilising the estimates of expenditure and relative price elasticity obtained together with forecasts of future urban population, the demand for staple foodstuffs until 1986 is estimated. In addition, the implications of different strategies for the supply of domestically produced staple foods to urban markets are examined. Particular attention is paid to the value of rice and wheat product imports necessary to complement such supply strategies. Finally, factors relating to an integrated pricing policy for all staple foodstuffs are discussed.

 REMARKS: Philoliche Wiedemann, 1821 was originally proposed within [= effectively as a subgenus of] Pangonia Latreille, 1802. Chainey & Oldroyd (1980: 286), Daniels (1989: 281) and Sabrosky (1999: 242) listed Wiedemann (1828: 95) as the first publication to make the name Philoliche available. However, Wiedemann (1821b: 4) gave characters for it and included the six species listed above. Lucas (1838: 21) and Desmarest (1859: 233) designated Tabanus fuscipennis Wiedemann, 1828 as the type species (the last of these works was followed by Sabrosky, 1999) but, although Tabanus fuscipennis Wiedemann, 1828 was originally included in the Wiedemann (1828) work, it was not an originally included species in Wiedemann (1821b), thus designations of it are invalid. The earliest designation based on originally included species is Tabanus rostratus Linnaeus, 1758 by Coquillett (1910: 588).

description: With numerical simulations of the mW model of water, we investigate the energetic stability of crystalline clusters for both Ice I (cubic and hexagonal ice) and for the metastable Ice 0 phase as a function of the cluster size. Under a large variety of forming conditions, we find that the most stable cluster changes as a function of size: at small sizes the Ice 0 phase produces the most stable clusters, while at large sizes there is a crossover to Ice I clusters. We further investigate the growth of crystalline clusters with the seeding technique and study the growth patterns of different crystalline clusters. While energetically stable at small sizes, the growth of metastable phases (cubic and Ice 0) is hindered by the formation of coherent grain boundaries. A five-fold symmetric twin boundary for cubic ice, and a newly discovered coherent grain boundary in Ice 0, that promotes cross nucleation of cubic ice. Our work reveals that different local structures can compete with the stable phase in mW water, and that the low energy cost of particular grain boundaries might play an important role in polymorph selection.

description: The proportion of zeros in event-count processes may be inflated by an additional mechanism by which zeros are created. This has given rise to statistical models that accommodate zero inflation; these are available in Stata through the zip and zinb commands. The Vuong (1989, Econometrica 57: 307–333) test is regularly used to determine whether estimating a zero-inflation component is appropriate or whether a single-equation count model should be used. The use of the Vuong test in this case is complicated by the fact that zero-inflated models involve the estimation of several more parameters than the single-equation models. Although Vuong (1989, Econometrica 57: 307–333) suggested corrections to the test statistic to address the comparison of models with different numbers of parameters, Stata does not implement any such correction. The result is that the Vuong test used by Stata is biased toward supporting the model with a zero-inflation component, even when no zero inflation exists in the generative process. We provide new Stata commands for computing the Vuong statistic with corrections based on the Akaike and Bayesian (Schwarz) information criteria. In an extensive Monte Carlo study, we illustrate the bias inherent in using the uncorrected Vuong test, and we examine the relative merits of the Akaike and Schwarz corrections. Then, in an empirical example from international relations research, we show that errors in selecting an event-count model can have clear implications for substantive conclusions.
Image of the Janis-Newman-Winicour naked singularity with a thin accretion disk

description: We study the optical appearance and the apparent radiation flux of a thin accretion disk around the static Janis-Newman-Winicour naked singularity. We confine ourselves to the astrophysically most relevant case, when the solution possesses a photon sphere, assuming that the radiation emitted by the disk is described by the Novikov-Thorne model. The observable images resemble closely the visual appearance of the Schwarzschild black hole, as only quantitative differences are present. For the Janis-Newman-Winicour solution the accretion disk appears smaller, and its emission is characterized by a higher peak of the radiation flux. In addition, the most significant part of the radiation is concentrated in a closer neighbourhood of the flux maximum. The results are obtained independently by two alternative methods, consisting of a semi-analytical scheme using the spherical symmetry of the spacetime, and a fully numerical ray-tracing procedure valid for any stationary and axisymmetric spacetime.

description: We show that the redshift of pressureless matter density due to the expansion of the universe generically induces small oscillations in the stabilized radius of extra dimensions (the radion field). The frequency of these oscillations is proportional to the mass of the radion and can have interesting cosmological consequences. For very low radion masses $m_b$ ($m_b\sim10-100 H_0\simeq10^{-32} eV$) these low frequency oscillations lead to oscillations in the expansion rate of the universe. The occurrence of acceleration periods could naturally lead to a resolution of the coincidence problem, without need of dark energy. Even though this scenario for low radion mass is consistent with several observational tests it has difficulty to meet fifth force constraints. If viewed as an effective Brans-Dicke theory it predicts $ω=-1+\frac{1}{D}$ ($D$ is the number of extra dimensions), while experiments on scales larger than $1mm$ imply $ω>2500$. By deriving the generalized Newtonian potential corresponding to a massive toroidally compact radion we demonstrate that Newtonian gravity is modified only on scales smaller than $m_b^{-1}$. Thus, these constraints do not apply for $m_b>10^{-3} eV$ (high frequency oscillations) corresponding to scales less than the current experiments ($0.3mm$). Even though these high frequency oscillations can not resolve the coincidence problem they provide a natural mechanism for dark matter generation. This type of dark matter has many similarities with the axion.

description: We present methods for testing hypotheses and estimating confidence sets for structural parameters of economic models in the presence of instabilities and breaks of unknown form. These methods constructively explore information generated by changes in the data-generating process to improve the inference of parameters that remain stable over time. The proposed methods are suitable for models cast in the generalized method of moments framework, which makes their application wide. Moreover, they are robust to the presence of weak instruments. The genstest command in Stata implements these methods to conduct hypothesis tests and to estimate confidence sets.

description: We point out that slepton pairs produced via gauge boson fusion in anomaly mediated supersymmetry breaking (AMSB) model have very characteristic and almost clean signal at the Large Hadron Collider. In this article, we discuss how one lepton associated with missing energy and produced in between two high-$p_T$ and high-mass forward jets can explore quite heavy sleptons in this scenario.

description: Multi-modal data fusion has recently been shown promise in classification tasks in remote sensing. Optical data and radar data, two important yet intrinsically different data sources, are attracting more and more attention for potential data fusion. It is already widely known that, a machine learning based methodology often yields excellent performance. However, the methodology relies on a large training set, which is very expensive to achieve in remote sensing. The semi-supervised manifold alignment (SSMA), a multi-modal data fusion algorithm, has been designed to amplify the impact of an existing training set by linking labeled data to unlabeled data via unsupervised techniques. In this paper, we explore the potential of SSMA in fusing optical data and polarimetric SAR data, which are multi-sensory data sources. Furthermore, we propose a MAPPER-induced manifold alignment (MIMA) for semi-supervised fusion of multi-sensory data sources. Our proposed method unites SSMA with MAPPER, which is developed from the emerging topological data analysis (TDA) field. To our best knowledge, this is the first time that SSMA has been applied on fusing optical data and SAR data, and also the first time that TDA has been applied in remote sensing. The conventional SSMA derives a topological structure using k-nearest-neighbor (kNN), while MIMA employs MAPPER, which considers the field knowledge and derives a novel topological structure through the spectral clustering in a data-driven fashion. Experiment results on data fusion with respect to land cover land use classification and local climate zone classification suggest superior performance of MIMA.
