Asheville, North Carolina: U.S. Department of Agriculture, Forest Service, Southern Research Station. pp. 5-12.

Healthy ecosystems are those that are stable and sustainable, able to maintain their organization and autonomy over time while remaining resilient to stress (Costanza 1992). The Forest Health Monitoring (FHM) Program of the Forest Service, U.S. Department of Agriculture, with cooperating researchers within and outside the Forest Service and with State partners, quantifies the health of U.S. forests. The analyses and results outlined in sections 1 and 2 of this FHM annual national technical report offer a snapshot of the current condition of U.S. forests from a national or multi-State regional perspective, incorporating baseline investigations of forest ecosystem health, examinations of change over time in forest health metrics, and assessments of developing threats to forest stability and sustainability. For datasets collected on an annual basis, analyses are presented from 2009 data. For datasets collected over several years, analyses are presented at a longer temporal scale. Several chapters describe new techniques for analyzing forest health data as well as new applications of established techniques. Finally, section 3 of this report presents summaries of results from recently completed Evaluation Monitoring (EM) projects that have been funded through the FHM national program to determine the extent, severity and/or causes of specific forest health problems (Forest Health Monitoring 2010).

description: Este estudo tem por objetivo analisar a relação existente na formação dos preços de carne bovina in natura entre os países do MERCOSUL e dos Estados Unidos. O modelo econométrico utilizado busca identificar a relação de casualidade a partir da estimação de um Vetor Auto-regressivo (VAR). Ainda são analisadas as funções de impulsoresposta a fim de avaliar os efeitos de curto prazo sobre os preços da carne bovina. Por fim, é possível confirmar a existência de causalidade na formação de preços entre os países do MERCOSUL, bem como a intensidade e sentido dos choques nos preços em cada mercado analisado.-------------------The main objective of this study is to examine the relation between bovine meat prices in Mercosur countries and United States. The econometric model permits to identify the causality using a vector autoregressive model (VAR). In addition we analyze the impulse response function to investigate the short-time effects in bovine meat prices. Finally it is possible to confirm an existence of causality in the price definition for Mercosur countries. Also it evaluates the intensity and direction of prices shocks in each market.

description: One argument for keeping the physics GRE is that it can help applicants who might otherwise be missed in the admissions process stand out. In this work, we evaluate whether this claim is supported by physics graduate school admissions decisions. We used admissions data from five PhD-granting physics departments over a 2-year period (N=2537) to see how the fraction of applicants admitted varied based on their physics GRE scores. We compared applicants with low GPAs to applicants with higher GPAs, applicants from large undergraduate universities to applicants from smaller undergraduate universities, and applicants from selective undergraduate institutions to applicants from less selective undergraduate institutions. We also performed a mediation and moderation analysis to provide statistical rigor and to better understand the previous relationships. We find that for applicants who might otherwise have been missed (e.g. have a low GPA or attended a small or less selective school) having a high physics GRE score did not seem to increase the applicant's chances of being admitted to the schools. However, having a low physics GRE score seemed to penalize otherwise competitive applicants. Thus, our work suggests that the physics GRE does not, in fact, help applicants who might otherwise be missed stand out.

Monitoring the occurrence of forest pest and pathogen outbreaks is important at regional scales because of the significant impact insects and disease can have on forest health across landscapes (chapter 2). Survey data by the Forest Health Protection Program of the Forest Service from 2009 identified 62 different mortality-causing agents on nearly 4.69 million ha of forest in the conterminous United States. Similarly, defoliation damage attributed to 64 agents affected approximately 3.17 million ha. Significant large geographic hot spots of forest mortality were associated with mountain pine beetle in the West, while a smaller hot spot was associated with bronze birch borer in the northern Midwest. The largest hot spots of defoliation were also in the West, caused primarily by western spruce budworm. Forest tent caterpillar was associated with hot spots of defoliation in the East. Northern spruce engraver beetle was the most important cause of mortality in Alaska, while aspen leafminer was the most important defoliation agent there.
Promoting the rule of democratic law : the impact of non-institutional accountability mechanisms
Creators: name: Blanaru, Ana-Maria
Publisher: name: University of British Columbia
Year: 2009

description: Both theoretical and empirical analyses of the rule of law concentrate on the procedural, rather than the substantive dimensions of laws. In the context of the literature on the rule of law in democratizing states, I argue that this has led to insufficient attention being devoted to the substance of laws and constitutions. Moreover, theoretical accounts of mechanisms for promoting and protecting the rule of law, which concentrate on law enforcement, judicial independence and checks and balances among the branches of government, do not provide us with an analytical framework for examining non-institutional mechanisms that can account for variations in the strength of the rule of law over time. In this study, I introduce the argument that non-institutional accountability mechanisms (such as protests) employed by civil society and opposition political movements can be central to holding governments accountable and pressuring them to act in accordance with the rule of law, the constitution, and democratic principles. I develop a game-theoretic model that shows how the presence of non-institutional accountability mechanisms constrains the actions of executives who would otherwise transgress the laws or amend the constitution in a manner that undermines the democratic regime. Drawing upon recent evidence that shows the positive relationship between the rule of law and political stability in democratic states, I introduce new evidence that also shows the presence of this relationship in the gradually-democratizing states of the Arab world. I then examine the particular circumstances in which this relationship may be reversed in the short run, when non-institutional accountability mechanisms are employed because institutionalized accountability mechanisms are ineffective. Finally, I examine both rational choice and psychological theories of protest movements to elaborate strategies for facilitating the employment of non-institutional accountability mechanisms in order to protect the rule of law and democracy.

description: The M{ö}bius transform is a crucial transformation into the Boolean world; it allows to change the Boolean representation between the True Table and Algebraic Normal Form. In this work, we introduce a new algebraic point of view of this transformation based on the polynomial form of Boolean functions. It appears that we can perform a new notion: the M{ö}bius computation variable by variable and new computation properties. As a consequence, we propose new algorithms which can produce a huge speed up of the M{ö}bius computation for sub-families of Boolean function. Furthermore we compute directly the M{ö}bius transformation of some particular Boolean functions. Finally, we show that for some of them the Hamming weight is directly related to the algebraic degree of specific factors.

description: O Brasil é o terceiro maior produtor de frutas, entretanto, a participação nas exportações mundiais ainda é reduzida. A fruticultura consiste numa alternativa viável para o desenvolvimento uma vez que pode gerar renda a partir de reduzida área de produção, além de adotar mão-de-obra de forma intensa. A região Nova Alta Paulista apresenta características adequadas à atividade em termos de estrutura agrária e condições edafoclimáticas. Assim, esse estudo teve como objetivo caracterizar a fruticultura na região. Foram identificadas diversas barreiras ao desenvolvimento como a falta de coordenação entre os agentes das cadeias da fruticultura. Tais barreiras devem ser alvo de políticas públicas e privadas, pois os resultados podem beneficiar os agentes em termos de redução das incertezas relacionadas com a atividade, acesso à tecnologia, à informação e ao aprendizado, contribuindo para o desenvolvimento da região.------------------Brazil is the third fruit producer in the world; however, the participation in global exports is still low. Fruits agribusiness consists in a viable alternative for local development since it is able to generate income from a reduced area and adopts intensive labor force. Nova Alta Paulista region presents adequate characteristics for this activity in terms of agrarian structure and soil and climate conditions. This research had as main objective to characterize fruit agribusiness in Nova Alta Paulista region. Several barriers were identified as the lack of coordination among agents within the chains. Such barriers should be overcome by development of private and public policies, as the results may benefit the agents in terms of uncertainty reduction, access to technology, information and knowledge, favoring region development.

description: It has long been acknowledged that women with children require social support to promote their health and wellbeing, as well as that of their children. However, the dominant conceptualizations of support have been heavily influenced by Western family norms. The consequence, at best, has been to stifle our understanding of the nature and consequences of support for mothers and children. At worst, it has led to systematic discrimination negatively impacting maternal–child health. To fully engage with the complexities of social support, we must take multidisciplinary or interdisciplinary approaches spanning diverse cultural and geographical perspectives. However, multidisciplinary knowledge-processing can be challenging, and it is often unclear how different studies from different disciplines relate. To address this, we outline two epistemological frameworks—the scientific approach and Tinbergen's four questions that can be useful tools in connecting research across disciplines. In this theme issue on ‘Multidisciplinary perspectives on social support and maternal–child health’, we attempt to foster multidisciplinary thinking by presenting work from a diverse range of disciplines, populations and cultures. Our hope is that these tools, along with papers in this issue, help to build a holistic understanding of social support and its consequences for mothers and their children. Overall, a multidisciplinary perspective points to how the responsibility of childrearing should not fall solely onto mothers. Indeed, this multidisciplinary issue demonstrates that successful childrearing is consistently an activity shared beyond the mother and the nuclear family: an insight that is crucial to harnessing the potential of social support to improve maternal–child health.This article is part of the theme issue ‘Multidisciplinary perspectives on social support and maternal–child health’.

Such spacetimes include as special cases analytically known black hole Kerr and Schwarzschild spacetimes, as well as the analytic Hartle-Thorne spacetime and all numerically constructed spacetimes relevant for rotating neutron stars. Our derivation follows directly from energy and angular momentum conservation and it uses the concept of the effective potential. It has never been published, except for a few special cases, but it has already become a part of the common knowledge in the field.

Asheville, North Carolina: U.S. Department of Agriculture, Forest Service, Southern Research Station. pp. 31-39.
Forest fire occurrence outside the historic range of frequency and intensity can result in extensive economic and ecological impacts. The detection of regional patterns of fire occurrence can allow for the identification of areas at greatest risk of significant impact and for the selection of locations for more intensive analysis. In 2009, the Central California Coast experienced the most fires per 100 km2 of forested area, while ecoregions in the southern plains of Oklahoma and Texas also had high densities of forest fire occurrence. In Alaska, an extremely high density of forest fires occurred in the Yukon Flats ecoregion. Several geographical hot spots of fire occurrence were located near the Pacific Coast and throughout the coastal plains of the South. The pattern and degree of clustering of these hot spots suggests that fires were more evenly distributed across the conterminous States than in recent years, with slightly higher concentrations in a few areas.

description: Population growth is causing a high demand for construction and cement use and, at the same time, increasing the amount of MSW (Municipality Solid Waste). One of the solutions that can help to reduce the amount of waste in developing countries, along with the demand for fossil fuels, is using co-processing and incineration technologies in the cement industry.The objective of a waste management system is not to dispose of waste products, but it is to supply the economy with secondary raw materials and energy from waste. In the cement industry, co-processing is one of the best ways of recovering material and energy from waste. The desired waste material, to be used as a fuel, is available usually within the state or the country.Algeria, as a middle-income country, with a 72% urbanisation, faces waste management challenge. The industry sector consumes 25 % of the final gas consumption in the country. This study aims to reduce gas consumption in ement industries, one of the intensive consumers in the industry sector.Waste oil, plastic, and MSW (Municipal Solid Waste) as alternative fuels in the burning process of a cement industry are studied. The inject points are the main burner, calciner, and combustion chamber. Based on the injection point and replacement ratio, four different projects are analyzed:1. Waste Co-Processing in the Main Burner - 100% waste oil2. Waste Co-Processing in the Main Burner - 70% waste oil and 30% plastic3. Waste Incineration in the Calciner - 50% plastic and 50% MSW4. Waste Incineration in the Calciner and Combustion Chamber - 50% plasticand 50% MSWAnnually, at the targeted industry, 1,620,000 m3 waste can be incinerated in thecalciner and combustion chamber. Incinerating waste only in the calciner needs ahigher amount of averaged calorific value and waste treatment process, andapproximately 1,200,000 m3 waste can be burned. Waste co-processing in the main burner project can reduce the amount of waste oil 120,000 m3 per year. In the case of using a 30% replacement ratio with plastic also in the main burner, almost a waste volume reduction of 250,000 m3 per year can be seen.

description: We analyzed a coronal loop observed with the Normal Incidence Spectrometer (NIS), which is part of the Coronal Diagnostic Spectrometer (CDS) on board the Solar and Heliospheric Observatory (SOHO). The measured Doppler shifts and proper motions along the selected loop strongly indicate unidirectional flows. Analysing the Emission Measure Curves of the observed spectral lines, we estimated that the temperature along the loop was about 380000 K. We adapted a solution of the ideal MHD steady equations to our set of measurements. The derived energy balance along the loop, as well as the advantages/disadvantages of this MHD model for understanding the characteristics of solar coronal loops are discussed.

description: Wir prüfen zwei verschiedene Methoden um automatisch über streng monotone fallende oder streng monoton steigende Kantenzüge in kantengewichteten Graphen zu argumentieren. Zunächst präsentieren wir eine Formulierung als prädikatenlogisches Problem und evaluieren die Anwendung automatischer Theorembeweiser. Wir zeigen die Nachteile dieses Ansatzes, durch experimentelle Auswertung der Abhängigkeit der gebrauchten Zeit von der Größe des Graphen. Motiviert von diesen Einschränkungen präsentieren wir einen Beweis für eine untere Grenze der Länge von streng monotonen Kantenzügen, der nicht von der Größe des Graphen abhängt. Wir formalisieren Eigenschaften streng monoton fallender und streng monoton steigender Kantenzüge im Beweisassistenen Isabelle/HOL und verifizieren den Beweis der unteren Grenze der Länge des längsten streng monoton fallenden Kantenzugs. Dafür erweitern wir Isabelles Bibliothek für Graphentheorie mit einem Algorithmus, der die Länge des längsten streng monoton fallenden Kantenzugs von einem Knoten für eine gegebene Verteilung der Kantengewichte berechnet. Des Weiteren beweisen wir in Isabelle, dass in einem ungerichtetem Graphen jeder streng monoton fallende Kantenzug auch ein streng monoton steigender Kantenzug ist. Außerdem präsentieren wir einen konstruktiven Beweis, der eine obere Grenze der minimalen Länge eines streng monotonen Kantenzug in vollständigen Graphen zeigt. Im Zuge dessen geben wir auch einen Algorithmus zur Erzeugung von vollständigen Graphen beliebiger Größe an, die zeigen, dass Graphen mit einer bestimmten maximalen Länge von Kantenzügen existieren.
description: We survey two methods to reason about ordered trails in edge-weighted graphs. Firstly, we provide an encoding in first-order logic in order to apply automated theorem provers to the problem. Conducting experiments on the size of the input instance, we show the disadvantages of this approach. Motivated by this we present a symbolic proof of the lower bound on the length of strictly ordered trails in weighted graphs. Then, we formalize strictly ordered trails in the proof assistant Isabelle/HOL. We express and prove properties of these trails and verify the lower bounds on the length in Isabelle. We do so by extending the graph theory library of Isabelle/HOL with an algorithm computing the length of a longest strictly decreasing graph trail starting from a vertex for a given weight distribution, and prove that in an undirected graph any decreasing trail is also an increasing one. We also present a symbolic proof that shows an upper bound on the minimum length of strictly ordered trails. To this end we present an algorithm to construct graphs that witness the upper bound an implementation of this algorithm.

description: Metal-halide perovskites are rapidly emerging as solution-processable optical materials for light emitting applications. Here we adopt a plasmonic metamaterial approach to enhance photoluminescence emission and extraction of methylammonium lead iodide (MAPbI3) thin films, based on the Purcell effect. We show that hybridization of the active metal-halide film with resonant nanoscale sized slits carved into a gold film can yield more than one order of magnitude enhancement of luminescence intensity, and nearly threefold reduction of luminescence lifetime. This shows the effectiveness of resonant nanostructures in controlling metal-halide perovskite light emission properties over a tunable spectral range, a viable approach toward highly efficient perovskite light emitting devices and single-photon emitters.

description: This paper uses a choice based conjoint analysis in an attempt to develop a consumer profile for the new market for black consumers. Although the different statistical packages used variants of the MNL model, the results were significantly similar with no contradictions in their results and the model provided here had the best statistical significance. Despite the models’ imminent statistical insignificance, they suggested valuable notions about black consumers’ wine choice determinants. Age, gender and the choice of favourite red wine may be used to segment the market and the other significant coefficients will affect the marketing and distribution choices to be followed by wine companies.

description: Although South Africans are not predominantly wine drinkers, the industry is looking for ways to develop the local market to balance exports. The black middle class, increasingly referred to as the Black Diamonds are the most powerful marketing trend in the last 10 years as they have emerged as the strongest buying influence in the economy and making inroads in understanding this market presents a good opportunity. The data used in this paper was collected from an integration of a consumer behaviour survey; as well as personal interviews and focus group discussions. The paper asserts that the key factors influencing the South African consumers’ behaviour are age, gender, income, race and wine drinking history. The paper also asserts that not only are the black middle class are different from the white middle class but within the Black Diamonds different segments exist. The industry should particularly focus on marketing to the women and the “Start me up” age group in the group as there is limited consumer knowledge about wines, but a high willingness to experiment. The paper also suggests various new brand communication platforms that can be explored to reach this market as well as co-opetition between industry stakeholders.

description: We theoretically investigate the dynamics of magnetic hedgehogs, which are three-dimensional topological spin textures that exist in common magnets, focusing on their transport properties and connections to spintronics. We show that fictitious magnetic monopoles carried by hedgehog textures obey a topological conservation law, based on which a hydrodynamic theory is developed. We propose a nonlocal transport measurement in the disordered phase, where the conservation of the hedgehog flow results in a nonlocal signal decaying inversely proportional to the distance. The bulk-edge correspondence between hedgehog number and skyrmion number, the fictitious electric charges arising from magnetic dynamics, and the analogy between bound states of hedgehogs in ordered phase and the quark confinement in quantum chromodynamics are also discussed. Our study points to a practical potential in utilizing hedgehog flows for long-range neutral signal propagation or manipulation of skyrmion textures in three-dimensional magnetic materials.

Maternal inattention and impulsivity, and parenting behaviors
Creators: name: Chen, Mandy Yao-Min
Publisher: name: University of British Columbia

description: Recent studies on adults with ADHD have consistently shown an association between ADHD symptomatology and parenting impairments. This study extends previous research by examining whether inattention and impulsivity in a community sample of mothers are associated with different patterns of parenting deficits. Seventy mother-son dyads participated in the study, and the boys ranged between 4 and 8 years of age. Both negative and positive dimensions of parenting behaviors, as well as self-report and observational measures of parenting were included. Results showed that maternal inattention was uniquely associated with parenting overreactivity, inconsistent discipline, and lower involvement after controlling for impulsivity; however, maternal impulsivity was not uniquely related to any of the parenting constructs after controlling for inattention. Further, the associations between maternal inattention and parenting overreactivity and inconsistent discipline remained significant even after controlling for maternal hostility and depression, and child behavior problems. Possible reasons for the different patterns of associations between maternal inattention and impulsivity, and parenting are discussed.

description: We make an estimation of the value of the Gromov norm of the Cartesian product of two surfaces. Our method uses a connection between these norms and the minimal size of triangulations of the products of two polygons. This allows us to prove that the Gromov norm of this product is between 32 and 52 when both factors have genus 2. The case of arbitrary genera is easy to deduce form this one.

description: Pluto has a heterogeneous surface, despite a global haze deposition rate of ~1 micrometer per orbit (Cheng et al., 2017; Grundy et al., 2018). While there could be spatial variation in the deposition rate, this has not yet been rigorously quantified, and naively the haze should coat the surface more uniformly than was observed. One way (among many) to explain this contradiction is for atmospheric pressure at the surface to drop low enough to interrupt haze production and stop the deposition of particles onto part of the surface, driving heterogeneity. If the surface pressure drops to less than 10^-3 - 10^-4 microbar and the CH4 mixing ratio remains nearly constant at the observed 2015 value, the atmosphere becomes transparent to ultraviolet radiation (Young et al., 2018), which would shut off haze production at its source. If the surface pressure falls below 0.06 microbar, the atmosphere ceases to be global, and instead is localized over only the warmest part of the surface, restricting the location of deposition (Spencer et al., 1997). In Pluto's current atmosphere, haze monomers collect together into aggregate particles at beginning at 0.5 microbar; if the surface pressure falls below this limit, the appearance of particles deposited at different times of year and in different locations could be different. We use VT3D, an energy balance model (Young, 2017), to model the surface pressure on Pluto in current and past orbital configurations for four possible static N2 ice distributions: the observed northern hemisphere distribution with (1) a bare southern hemisphere, (2) a south polar cap, (3) a southern zonal band, and finally (4) a distribution that is bare everywhere except inside the boundary of Sputnik Planitia. We also present a sensitivity study showing the effect of mobile N2 ice...(cont.)

description: Recently, there have been some breakthroughs in graph analysis by applying the graph neural networks (GNNs) following a neighborhood aggregation scheme, which demonstrate outstanding performance in many tasks. However, we observe that the parameters of the network and the embedding of nodes are represented in real-valued matrices in existing GNN-based graph embedding approaches which may limit the efficiency and scalability of these models. It is well-known that binary vector is usually much more space and time efficient than the real-valued vector. This motivates us to develop a binarized graph neural network to learn the binary representations of the nodes with binary network parameters following the GNN-based paradigm. Our proposed method can be seamlessly integrated into the existing GNN-based embedding approaches to binarize the model parameters and learn the compact embedding. Extensive experiments indicate that the proposed binarized graph neural network, namely BGN, is orders of magnitude more efficient in terms of both time and space while matching the state-of-the-art performance.

description: Pretende-se partir de uma breve revisão sobre a noção de “Desenvolvimento Rural”. Em 2001, a Revista Estudos Avançados da USP publicou em volume 15, número 43, o Dossiê Desenvolvimento Rural, cujo conteúdo apresenta diversos enfoques. Optou-se neste trabalho pela resenha dos artigos de três autores (Veiga, J. Eli; Navarro, Zander; Silva, José Graziano da). Trata-se realmente de um dossiê, pois se revela como uma síntese das principais discussões que envolvem tanto o debate sobre desenvolvimento como a especificidade do desenvolvimento rural brasileiro. O interesse em desenvolver essa primeira reflexão sobre os referenciais conceituais, à luz de bibliografias contemporânea relacionadas à própria noção de desenvolvimento rural, deve-se a diversas indagações e certo estranhamento a visão de desenvolvimento rural ora no âmbito do mercado ora como ação de Estado. Observou-se a necessidade de constituir um arcabouço teórico que nos permitisse identificar quais as interfaces da noção de desenvolvimento rural, ou noções de desenvolvimento rural, com a teoria econômica. Por um lado, a primeira vista, percebe-se que vários atores políticos utilizam esta referencia com base em alguns princípios básicos como a melhoria da condição de vida da população (bem-estar) ou alterações na estrutura produtiva e de serviços das áreas rurais e a relação Estado e mercado. ----------------------------------------------It is from a brief review on the concept of "rural development". In 2001, the Journal of Advanced Studies USP published in volume 15, number 43, the Rural Development Dossier, the content of which presents several approaches. Our choice is to work for the review of the articles of three authors (Veiga, Eli J.; Navarro, Zander; Silva, José Graziano's). This is really a dossier because it is as a summary of the main discussions involving both the debate on development as the specificity of rural development. The interest in developing this first reflection on the conceptual reference in the light of contemporary bibliographies related to the concept of rural development, is due to several questions and some strangeness the vision of rural development now under the market now with action of state. There is a need to provide a theoretical framework that would allow us identify the interfaces of the concept of rural development, or notions of rural development, with economic theory. First, the first sight, realizes that several political actors use this reference based on some basic principles such as the improvement of the condition of living of the (welfare) or changes in the production structure and services of rural areas and State and market relationship.
