Risk and Uncertainty

description: In recent farm policy debates, proposals for a whole-farm revenue safety net program have been put forward that could provide a farm-income safety net for a wide variety of farming activities. These proposals include income- stabilization accounts and whole-farm revenue insurance. Risk protection from income-stabilization accounts would depend on the reserves in individual accounts and the structure of program benefits. Experience with farm savings accounts in Canada and Australia suggests that lack of adequate account balances and buildup of balances beyond the level required for risk management can reduce program effectiveness. Whole-farm revenue insurance could overcome these problems since coverage would not depend on the farmer's ability to build an account balance and benefits would only be realized when the farmer suffers a drop in income. However, the complexity of factors affecting income variability raises questions about the feasibility of a whole-farm insurance plan.

description: Theoretical arguments suggest that protoplanetary disks around young stars should start small and grow with the addition of high angular momentum material to reach the radii of several hundred AUs that characterize the disks around optically visible T Tauri stars. Examples of much more compact disks, with radii much less than 100 AU, have been found around some very young stars, but in all cases tidal truncation from a near binary companion provides a ready explanation for the small disk size. We report here an example of a compact, possibly isolated disk around the class 0 object IRAS16293-2422B, which is thought to be among the youngest protostars known. This disk has a Gaussian half power radius of only $\sim$8 AU, and a detailed, self-consistent, accretion disk model indicates an outer radius of only 26 AU. This discovery supports the notion that protoplanetary disks start small and grow with time, although other explanations for the compact size cannot be ruled out, including gravitational instability in its outer parts and tidal truncation from the close approach of a now distant stellar companion.

description: Interactions among individuals in natural populations often occur in a dynamically changing environment. Understanding the role of environmental variation in population dynamics has long been a central topic in theoretical ecology and population biology. However, the key question of how individuals, in the middle of challenging social dilemmas (e.g., the "tragedy of the commons"), modulate their behaviors to adapt to the fluctuation of the environment has not yet been addressed satisfactorily. Utilizing evolutionary game theory and stochastic games, we develop a game-theoretical framework that incorporates the adaptive mechanism of reinforcement learning to investigate whether cooperative behaviors can evolve in the ever-changing group interaction environment. When the action choices of players are just slightly influenced by past reinforcements, we construct an analytical condition to determine whether cooperation can be favored over defection. Intuitively, this condition reveals why and how the environment can mediate cooperative dilemmas. Under our model architecture, we also compare this learning mechanism with two non-learning decision rules, and we find that learning significantly improves the propensity for cooperation in weak social dilemmas, and, in sharp contrast, hinders cooperation in strong social dilemmas. Our results suggest that in complex social-ecological dilemmas, learning enables the adaptation of individuals to varying environments.
Evidence for a fundamental stellar upper mass limit from clustered star formation, and some implications therof

description: Theoretical considerations lead to the expectation that stars should not have masses larger than about m_{max*}=60-120Msun, while the observational evidence has been ambiguous. Only very recently has a physical stellar mass limit near 150Msun emerged thanks to modern high-resolution observations of local star-burst clusters. But this limit does not appear to depend on metallicity, in contradiction to theory. Important uncertainties remain though. It is now also emerging that star-clusters limit the masses of their constituent stars, such that a well-defined relation between the mass of the most massive star in a cluster and the cluster mass, m_{max}=F(M_ecl) \le m_{max*}\approx 150Msun, exists. One rather startling finding is that the observational data strongly favour clusters being built-up by consecutively forming more-massive stars until the most massive stars terminate further star-formation. The relation also implies that composite populations, which consist of many star clusters, most of which may be dissolved, must have steeper composite IMFs than simple stellar populations such as are found in individual clusters. Thus, for example, 10^5 Taurus--Auriga star-forming groups, each with 20 stars, will ever only sample the IMF below about 1Msun. This IMF will therefore not be identical to the IMF of one cluster with 2 times 10^6 stars. The implication is that the star-formation history of a galaxy critically determines its integrated galaxial IMF and thus the total number of supernovae per star and its chemical enrichment history. Galaxy formation and evolution models that rely on an invariant IMF would be wrong.

description: Most farms in the United States- 98 percent in 2003- are family farms. They are organized as proprietorships, partnerships, or family corporations. Even the largest farms tend to be family farms, although they are more likely to have more than one operator. Very large family farms and nonfamily farms account for a small share of farms but a large-and growing-share of farm sales. Small family farms account for most of the farms in the United States but produce a modest share of farm output. Median income for farm households is 10 percent greater than the median for all U.S. households, and small-farm households receive substantial off-farm income. Many farm households have a large net worth, reflecting the land-intensive nature of farming.

description: This article investigates discrete-time matrix-weighted consensus of multi-agent networks over undirected and connected graphs. We first present consensus protocols for the agents in common networks of symmetric matrix weights with possibly different update rates and switching network topologies. A special type of matrix-weighted consensus with non-symmetric matrix-weights that can render several consensus control scenarios such as ones with scaled/rotated updates and affine motion constraints is also considered. We employ Lyapunov stability theory for discrete-time systems and occasionally utilize Lipschitz continuity of the gradient of the Lyapunov function to show the convergence to a consensus of the agents in the system. Finally, simulation results are provided to illustrate the theoretical results.

description: The formation and structure of dark matter halos is studied by constrained simulations. A series of experiments of the formation of a 10^12 Msun/h halo is designed to study the dependence of the density profile on its merging history. We find that the halo growth consist of several quiescent phases intermitted by violent events, with the density well approximated by the NFW profile during the former phases. We find that (1) the NFW scale radius R_s stays constant during the quiescent phase and grows abruptly during the violent one. In contrast, the virial radius grows linearly during the quiescent and abruptly during the violent phases. (2) The central density stays unchanged during the quiescent phase while dropping abruptly during the violent phase, and it does not reflect the formation time of the halo. (3) The clear separation of the evolution of an individual halo into quiescent and violent phases implies that its entire evolution cannot be fitted by simple scaling relations.

description: Static source code analysis is a powerful tool for finding and fixing bugs when deployed properly; it is, however, all too easy to deploy it in a way that looks good superficially, but which misses important defects, shows many false positives, and brings the tool into disrepute. This article is a guide to the process of deploying a static analysis tool in a large organization while avoiding the worst organizational and technical pitfalls. My main point is the importance of concentrating on the main goal of getting bugs fixed, against all the competing lesser goals which will arise during the process.

description: Ten years after the first generation of genetically engineered (GE) varieties became commercially available, adoption of these varieties by U.S. farmers is widespread for major crops. Driven by farmers' expectations of higher yields, savings in management time, and lower pesticide costs, the adoption of corn, soybean, and cotton GE varieties has increased rapidly. Despite the benefits, however, environmental and consumer concerns may have limited acceptance of GE crops, particularly in Europe. This report focuses on GE crops and their adoption in the United States over the past 10 years. It examines the three major stakeholders of agricultural biotechnology and finds that (1) the pace of R&D activity by producers of GE seed (the seed firms and technology providers) has been rapid, (2) farmers have adopted some GE varieties widely and at a rapid rate and benefited from such adoption, and (3) the level of consumer concerns about foods that contain GE ingredients varies by country, with European consumers being most concerned.
Russian model forest in local forest politics : case study of the creation of a national park within the Gassinski Model Forest
Creators: name: Matsuo, Ichiro
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines local people's perception of the Gassinski Model Forest's (GMF) projects and activities in relation to local involvement and public communication. The GMF is the first model forest in the Russian Federation. A case study describing the creation of a national park (NP) within the GMF territory has been adopted for designing this research. The term "local involvement" for the purpose of this research, describes the inclusion of local people in the decision-making process and the term "public communication" refers to communication between the GMF and local people, including mass communication, a word-of-mouth communication and education. Public communication often accompanies local involvement. This research consists of six main chapters: introduction, background, conceptual framework, research methods, results and discussion and conclusion. In the background, firstly the organizational structure and characteristics of Canadian-style model forest programs and the GMF program are described, and then the continuity between the GMF program and the NP is explained. The conceptual framework of natural resources management is created to explain the focus of the questionnaire survey for this research. In the chapters concerned with the questionnaire survey, the methodology of the questionnaire survey was initially explained and then the results and the analyses are presented. According to the survey, more than 71% of the respondents are aware of the GMF. On the other hand, 71.8% of the respondents regard themselves as not being involved in the GMF. There are some statistical differences ( a =0.05) between groups (categorized by demographic information and responses to questions such as "Do you know anything about the GMF?" and "Do you consider yourself to be involved in any of the GMF?"). Many people do not have clear idea of the GMFs boundary. The results of the survey infer the GMFs projects and activities concerned with local involvement and public communication are perceived as insufficient by locals. The future National Park, which will be created within the GMF territory and the logical successor of the GMF, should learn from the GMFs experience in order to achieve the task of facilitating "ecological [environmental] education for locals."

description: The number of children in nonmetropolitan (nonmetro) areas increased by 3 percent between 1990 and 2000, compared with a 16-percent increase in metropolitan (metro) areas. A number of nonmetro counties lost population in the 1990s due to outmigration of young families, and the small increase in the number of nonmetro children may reflect that. Although rural child poverty rates declined in the 1990s, they remain higher (21 percent) than the rates for urban children (18 percent). In 2003, 2.7 million rural children under 18 were poor, representing 36 percent of the rural poor. The geographic distribution of child poverty-heavily concentrated in the South-is important for targeting poverty reduction policies and programs in nonmetro areas.

description: We have mapped the SiO J=5-4 line at 217GHz from the HH211 molecular outflow with the Submillimeter Array (SMA). The high resolution map (1.6''x0.9'') shows that the SiO J=5-4 emission comes from the central narrow jet along the outflow axis with a width of ~0.8'' (~250 AU) FWHM. The SiO jet consists of a chain of knots separated by 3-4'' (~1000 AU) and most of the SiO knots have counterparts in shocked H_2 emission seen in a new, deep VLT near-infrared image of the outflow. A new, innermost pair of knots are discovered at just +/-2'' from the central star. The line ratio between the SiO J=5-4 data and upper limits from the SiO J=1-0 data of Chandler & Richer (2001) suggests that these knots have a temperature in excess of 300-500 K and a density of (0.5-1) x10^7 cm^{-3}. The radial velocity measured for these knots is ~30 km/s, comparable to the maximum velocity seen in the entire jet. The high temperature, high density, and velocity structure observed in this pair of SiO knots suggest that they are closely related to the primary jet launched close to the protostar.

Large farms are far more likely to contract than small farms; in fact, contracts cover over half of the value of production from farms with at least $1 million in sales. Although use of both production and marketing contracts has grown over time, growth is more rapid for production contracts, which are largely used for livestock.

description: Under the Taxpayer Relief Act of 1997, most farmers will pay less Federal income tax, and farm families will find it easier to transfer the family farm across generations. The new law--the tax portion of 1997 legislation to balance the Federal budget by 2002--emerges from years of debate on proposals for tax simplification, broad tax reduction, and targeted relief for capital gains and estate taxes. The legislation is expected to generate a net tax reduction of $95 billion over 5 years for all taxpayers. A number of general and targeted tax relief provisions will reduce Federal taxes significantly for farmers and other rural residents, but also will increase the complexity of both Federal income and estate taxes. Farmers are expected to save more than $1.6 billion per year in Federal income taxes and $150-200 million in Federal estate taxes.

description: Public archival of analysis code and associated data is increasingly required or encouraged by scientific journals upon paper acceptance. Making both data and code available has numerous reported benefits, including increased transparency of methods, facilitation of future studies, and enabling complete reproduction of a paper's results. At present, however, there are few standards or checks on publicly available code, and in our experience it is rarely examined by reviewers. This leads to three questions: (1) how common is code sharing in recent papers; (2) how functional is the code, and (3) how reproducible are analyses when both code and data area publicly available? This study attempts to answer these three questions for recent papers on species distribution and abundance.

Revisiting Dionysus : Nietzsche, Heidegger, Foucault
Creators: name: DiPasquale, Steven Dean
Publisher: name: University of British Columbia
Year: 2009

description: This thesis challenges the traditional, Cartesian understanding of musical performance through a phenomenological investigation of aural experience. Whereas conventional approaches to musical performance prescribe separating 'work' from 'event' in order to ascertain musical meaning, we seek to reveal this dualistic framework as a limited knowledge paradigm and argue for a more situated account of performance that includes the myriad contingencies of its 'presentation.' To achieve this end, the writings of Friedrich Nietzsche, Martin Heidegger, and Michel Foucault are examined in order to construct a 'hermeneutic' framework for an interdisciplinary exchange between relevant works in philosophy, musicology, and acoustic science. A variety of contemporary rock, punk, postpunk, and electroacoustic performances are analyzed within this tri-partite model. Beginning with Nietzsche's concept of the Dionysian, we focus our attention on the musical event as a space of volatile, collective energies that can potentially be channeled into acts of mob violence, or into more positive forms of community. As we continue with the interdisciplinary dialogue, Heidegger and Foucault critique and refine Nietzsche's understanding of the Dionysian through their various analyses of human listening, mood, shared attunement, technology, power, and the body. B y charting Nietzsche's concept of the Dionysian as it is reinterpreted by Heidegger and Foucault, a much broader, more differentiated understanding o f musical experience is achieved.

description: This paper investigates maximum likelihood techniques to estimate component reliability from masked failure data in series systems. A likelihood model accounts for right-censoring and candidate sets indicative of masked failure causes. Extensive simulation studies assess the accuracy and precision of maximum likelihood estimates under varying sample size, masking probability, and right-censoring time for components with Weibull lifetimes. The studies specifically examine the accuracy and precision of estimates, along with the coverage probability and width of BCa confidence intervals. Despite significant masking and censoring, the maximum likelihood estimator demonstrates good overall performance. The bootstrap yields correctly specified confidence intervals even for small sample sizes. Together, the modelingframework and simulation studies provide rigorous validation of statistical learning from masked reliability data.

description: The AdS/CFT correspondence relates deformations of the CFT by "multi-trace operators" to "non-local string theories". The deformed theories seem to have non-local interactions in the compact directions of space-time; in the gravity approximation the deformed theories involve modified boundary conditions on the fields which are explicitly non-local in the compact directions. In this note we exhibit a particular non-local property of the resulting space-time theory. We show that in the usual backgrounds appearing in the AdS/CFT correspondence, the commutator of two bulk scalar fields at points with a large enough distance between them in the compact directions and a small enough time-like distance between them in AdS vanishes, but this is not always true in the deformed theories. We discuss how this is consistent with causality.

description: The coherent transmission technology using digital signal processing and advanced modulation formats, is bringing networks closer to the theoretical capacity limit of optical fibres, the Shannon limit. The in-phase quadrature electro-optic modulator that encodes information on both the amplitude and the phase of light, is one of the underpinning devices for the coherent transmission technology. Ideally, such modulator should feature low loss, low drive voltage, large bandwidth, low chirp and compact footprint. However, these requirements have been only met on separate occasions. Here, we demonstrate integrated thin-film lithium niobate in-phase/quadrature modulators that fulfil these requirements simultaneously. The presented devices exhibit greatly improved overall performance (half-wave voltage, bandwidth and optical loss) over traditional lithium niobate counterparts, and support modulation data rate up to 320 Gbit s-1. Our devices pave new routes for future high-speed, energy-efficient, and cost-effective communication networks.

description: Magnetic spots on low-mass stars can be traced and characterised using multi-band photometric light curves. Here we analyse an extensive data set for one active star, V1598Cyg, a known variable K dwarf which is either pre-main sequence and/or in a close binary system. Our light curve contains 2854 photometric data points, mostly in $V$, $R_c$, $I_c$, but also in $U$, $B$ and $Hα$, with a total baseline of about 4yr, obtained with small telescopes as part of the HOYS project. We find that V1598Cyg is a very fast rotator with a period of 0.8246 days and varying amplitudes in all filters, best explained as a signature of strong magnetic activity and spots. We fit the photometric amplitudes in $V$, $R_c$, $I_c$ and use them to estimate spot properties, using a grid-based method that is also propagating uncertainties. We verify the method on a partial data set with high cadence and all five broad-band filters. The method yields spot temperatures and fractional spot coverage with typical uncertainties of 100K and 3-4%, respectively. V1598Cyg consistently exhibits spots that are a few hundred degrees warmer than the photosphere, most likely indicating that the light curve is dominated by chromospheric plage. The spot activity varies over our observing baseline, with a typical time scale of 0.5-1yr, which we interpret as the typical spot lifetime. Combining our light curve with archival data, we find a six year cycle in the average brightness, that is probably a sign of a magnetic activity cycle.

Resummation techniques including relativistic formulations of chiral effective field theory and finite-range regularization (FRR) techniques are reviewed, with an emphasis on using lattice simulation results to constrain the parameters of the chiral expansion. We illustrate how the chiral extrapolation problem has been solved and use FRR techniques to identify the power-counting regime (PCR) of chiral perturbation theory. To fourth-order in the expansion at the 1% tolerance level, we find 0 \le m_pi \le 0.18 GeV for the PCR, extending only a small distance beyond the physical pion mass.

We estimate that at any given time, there should be $\sim1$ kilometer-scale or larger escaped asteroid in a transient direct (prograde) orbit with semimajor axis near that of Jupiter's ($a\simeq a_J$), with proportionally more smaller objects as determined by their size distribution. Most of these objects would be in the horseshoe dynamical state, which are hard to detect due to their moderate eccentricities (spending most of their time beyond 5 AU) and longitudes relative to Jupiter being spread nearly all over the sky. We also show that $\approx$1% of the transient asteroid co-orbital population is on retrograde orbits with Jupiter. This population, like the recently identified asteroid (514107) 2015 BZ$_{509}$, can spend millions of years with $a\simeq a_J$ including tens or hundreds of thousands of years formally in the retrograde 1:-1 co-orbital resonance. Escaping near-Earth asteroids (NEAs) are thus likely the precursors to the handful of known high-inclination objects with $a\simeq a_J$. We compare the production of jovian co-orbitals from escaping NEAs with those from incoming Centaurs. We find that temporary direct co-orbitals are likely dominated by Centaur capture, but we only find production of (temporary) retrograde jovian co-orbitals (including very long-lived ones) from the NEA source. We postulate that the primordial elimination of the inner Solar System's planetesimal population could provide a supply route for a metastable outer Solar System reservoir for the high-inclination Centaurs.

description: A theoretical approach is proposed to treat the spin dynamics in defect color centers. The method explicitly takes into account the spin dynamics in the ground state and excited state of the defect center as well as spin state dependent transitions involving the ground state and excited state, as well as an additional intermediate state. The proposed theory is applied to treat spin-dependent phenomena is silicon carbide, namely, in spin-3/2 silicon-vacancy centers, VSi or V2 centers. Theoretical predictions of magnetic field dependent photoluminescence intensity and optically detected magnetic resonance spectra demonstrate an important role of level crossing phenomena in the spin dynamics of the ground state and excited state. The results are in good agreement with previously published experimental data [Phys. Rev. X, 6 (2016) 031014].

description: A class of random discrete distributions $P$ is introduced by means of a recursive splitting of unity. Assuming supercritical branching, we show that for partitions induced by sampling from such $P$ a power growth of the number of blocks is typical. Some known and some new partition structures appear when $P$ is induced by a Dirichlet splitting.

description: Randomly diluted quantum boson and spin models in two dimensions combine the physics of classical percolation with the well-known dimensionality dependence of ordering in quantum lattice models. This combination is rather subtle for models that order in two dimensions but have no true order in one dimension, as the percolation cluster near threshold is a fractal of dimension between 1 and 2: two experimentally relevant examples are the O(2) quantum rotor and the Heisenberg antiferromagnet. We study two analytic descriptions of the O(2) quantum rotor near the percolation threshold. First a spin-wave expansion is shown to predict long-ranged order, but there are statistically rare points on the cluster that violate the standard assumptions of spin-wave theory. A real-space renormalization group (RSRG) approach is then used to understand how these rare points modify ordering of the O(2) rotor. A new class of fixed points of the RSRG equations for disordered 1D bosons is identified and shown to support the existence of long-range order on the percolation backbone in two dimensions. These results are relevant to experiments on bosons in optical lattices and superconducting arrays, and also (qualitatively) for the diluted Heisenberg antiferromagnet.
On independent permutation separability criteria

description: Recently P. Wocjan and M. Horodecki [quant-ph/0503129] gave a characterization of combinatorially independent permutation separability criteria. Combinatorial independence is a necessary condition for permutations to yield truly independent criteria meaning that that no criterion is strictly stronger that any other. In this paper we observe that some of these criteria are still dependent and analyze why these dependencies occur. To remove them we introduce an improved necessary condition and give a complete classification of the remaining permutations. We conjecture that the remaining class of criteria only contains truly independent permutation separability criteria. Our conjecture is based on the proof that for two, three and four parties all these criteria are truly independent and on numerical verification of their independence for up to 8 parties. It was commonly believed that for three parties there were 9 independent criteria, here we prove that there are exactly 6 independent criteria for three parties and 22 for four parties.

description: We show that single and multislit experiments involving matter waves may be constructed to assess correlations between the position and momentum of a single free particle. These correlations give rise to position dependent phases which develop dynamically and may play an important role in the interference patterns. For large enough transverse coherence lenght such interference patterns are noticeably different from those of a classical dispersion free wave.

description: The effect of retail grocery market structure on the speed of adjustment of retail food prices to changes in producer prices, real wages, and the cost of energy was examined for SMSAs. Evidence failed to support the implication of the Mason-Bain paradigm that increased concentration reduces market efficiency as reflected in speed of retail price adjustment. Evidence of strong intertemporal relationships between change in producer prices and retail prices found for the categories meat, poultry, fish, eggs and cereal and baker products provide support to the hypothesis of cost-push inflation.

New procedure to estimate plasma parameters through the q-Weibull distribution by using a Langmuir probe in a cold plasma

description: We describe a procedure to obtain the plasma parameters from the I-V Langmuir curve by using the Druyvesteyn equation. We propose to include two new parameters, $q$ and $r$, to the usual plasma parameters: plasma potential ($V_p$), floating potential ($V_f$), electron density ($n$), and electron temperature ($T$). These new parameters can be particularly useful to represent non-Maxwellian distributions. The procedure is based on the fit of the I-V Langmuir curve with the $q$-Weibull distribution function, and is motivated by recent works which use the $q$-exponential distribution function derived from Tsallis statistics. We obtain the usual plasma parameters employing three techniques: the numerical differentiation using Savitzky Golay (SG) filters, the $q$-exponential distribution function, and the $q$-Weibull distribution function. We explain the limitations of the $q$-exponential function, where the experimental data $V>V_p$ needs to be trimmed beforehand, and this results in a lower accuracy compared to the numerical differentiation with SG. To overcome this difficulty, the $q$-Weibull function is introduced as a natural generalization to the $q$-exponential distribution, and it has greater flexibility in order to represent the concavity change around $V_p$. We apply this procedure to analyze the measurements corresponding to a nitrogen $N_2$ cold plasma obtained by using a single Langmuir probe located at different heights from the cathode. We show that the $q$ parameter has a very stable numerical value with the height. This work may contribute to clarify some advantages and limitations of the use of non-extensive statistics in plasma diagnostics, but the physical interpretation of the non-extensive parameters in plasma physics remains not fully clarified, and requires further research.

The spontaneous exchange bias effect on La$_{1.5}$Ba$_{0.5}$CoMnO$_{6}$

description: La$_{1.5}$Ba$_{0.5}$CoMnO$_{6}$ is a re-entrant cluster glass material exhibiting a robust negative exchange bias (EB) effect even after being cooled from an unmagnetized state down to low temperature in zero magnetic field. Here we thoroughly investigate this phenomena by performing magnetization as a function of applied field [$M(H)$] measurements at several different temperatures and maximum applied magnetic fields ($H_m$). The spontaneous EB (SEB) effect is observed below 20 K, and shows a maximum value for $H_m$ = 75 kOe. The effect is greatly enhanced when the $M(H)$ curves are measured after the system is cooled in the presence of a magnetic field. The asymmetry of the $M(H)$ curves here investigated can be well described by a recently proposed model based on the unconventional relaxation of the SG-like moments during the hysteresis cycle.
