description: An estimated 88.2 percent of U.S. households were food secure throughout the entire year in 2017, meaning they had access at all times to enough food for an active, healthy life for all household members. The remaining households (11.8 percent) were food insecure at least some time during the year, including 4.5 percent with very low food security, meaning that at times the food intake of one or more household members was reduced and their eating patterns were disrupted because the household lacked money and other resources for obtaining food. Declines from 2016 in food insecurity overall and in very low food security were statistically significant. The rate of food insecurity declined from 12.3 percent in 2016, and very low food security declined from 4.9 percent, continuing downward trends. Among children, changes from 2016 in food insecurity and very low food security were not statistically significant. Children and adults were food insecure in 7.7 percent of U.S. households with children in 2017, versus 8.0 percent in 2016. Very low food security among children was 0.7 percent in 2017, essentially unchanged from 2016. In 2017, the typical food-secure household spent 23 percent more on food than the typical food-insecure household of the same size and household composition. About 58 percent of food-insecure households participated in one or more of the three largest Federal food and nutrition assistance programs (Supplemental Nutrition Assistance Program (SNAP, formerly food stamps); Special Supplemental Nutrition Program for Women, Infants, and Children (WIC); and the National School Lunch Program) during the month prior to the 2017 survey.

description: We give a theoretical analysis of published experimental studies of the effects of impurities and disorder on the superconducting transition temperature, T_c, of the organic molecular crystals kappa-ET_2X and beta-ET_2X (where ET is bis(ethylenedithio)tetrathiafulvalene and X is an anion eg I_3). The Abrikosov-Gorkov (AG) formula describes the suppression of T_c both by magnetic impurities in singlet superconductors, including s-wave superconductors and by non-magnetic impurities in a non-s-wave superconductor. We show that various sources of disorder lead to the suppression of T_c as described by the AG formula. This is confirmed by the excellent fit to the data, the fact that these materials are in the clean limit and the excellent agreement between the value of the interlayer hopping integral, t_perp, calculated from this fit and the value of t_perp found from angular-dependant magnetoresistance and quantum oscillation experiments. If the disorder is, as seems most likely, non-magnetic then the pairing state cannot be s-wave. We show that the cooling rate dependence of the magnetisation is inconsistent with paramagnetic impurities. Triplet pairing is ruled out by several experiments. If the disorder is non-magnetic then this implies that l>=2, in which case Occam's razor suggests that d-wave pairing is realised. Given the proximity of these materials to an antiferromagnetic Mott transition, it is possible that the disorder leads to the formation of local magnetic moments via some novel mechanism. Thus we conclude that either kappa-ET_2X and beta-ET_2X are d-wave superconductors or else they display a novel mechanism for the formation of localised moments. We suggest systematic experiments to differentiate between these scenarios.

description: Temperatures over the next century are expected to rise to levels detrimental to crop growth and yield. As the atmosphere warms without additional water vapor input, vapor pressure deficit (VPD) increases as well. Increased temperatures and accompanied elevated VPD levels can both lead to negative impacts on crop yield. The independent importance of VPD, however, is often neglected or conflated with that from temperature due to a tight correlation between the two climate factors. We used a coupled process-based crop (MAIZSIM) and soil (2DSOIL) model to gain a mechanistic understanding of the independent roles temperature and VPD play in crop yield projections, as well as their interactions with rising CO2 levels and changing precipitation patterns. We found that by separating out the VPD effect from rising temperatures, VPD increases had a greater negative impact on yield compared to that from warming. The negative impact of these two factors varied with precipitation levels and influenced yield through separate mechanisms. Warmer temperatures caused yield loss mainly through shortening the growing season, while elevated VPD increased water loss and triggered several water stress responses such as reduced photosynthetic rates, lowered leaf area development, and shortened growing season length. Elevated CO2 concentrations partially alleviated yield loss under warming or increased VPD conditions through water savings, but the impact level varied with precipitation levels and was most pronounced under drier conditions. These results demonstrate the key role VPD plays in crop growth and yield, displaying a magnitude of impact comparative to temperature and CO2. A mechanistic understanding of the function of VPD and its relation with other climate factors and management practices is critical to improving crop yield projections under a changing climate.

description: The discovery of novel structural and physical properties in the $A$-site ordered manganite $R$BaMn$_{2}$O$_{6}$ ($R$ = Y and rare earth elements) has demanded new comprehension about perovskite manganese oxides. In the present study, the $A$-site disordered form, $R_{0.5}$Ba$_{0.5}$MnO$_{3}$, has been investigated and compared with both $R$BaMn$_{2}$O$_{6}$ and $R_{0.5}A_{0.5}$MnO$_{3}$ ($A$: Sr, Ca) in the structures and electromagnetic properties. $R_{0.5}$Ba$_{0.5}$MnO$_{3}$ has a primitive cubic perovskite cell in the structure and magnetic glassy states are dominant as its ground state, in contrast to the ordinary disordered $R_{0.5}A_{0.5}$MnO$_{3}$ ($A$: Sr, Ca). In Pr-compounds with various degrees of Pr/Ba randomness at the $A$-sites, the $A$-site disorder gradually suppresses both ferromagnetic and A-type antiferromagnetic transitions and finally leads to a magnetic glassy state in Pr$_{0.5}$Ba$_{0.5}$MnO$_{3}$. A peculiar behavior, multi-step magnetization and resistivity change, has been observed in Pr$_{0.5}$Ba$_{0.5}$MnO$_{3}$. These properties could be closely related to any spatial heterogeneity caused by the random distribution of Ba$^{2 +}$ and $R^{3 +}$ with much different ionic radius.

description: Surface modification of Fe3O4 nanoparticles was performed by immobilizing silica, metformine, and amine. Mixed matrix PES nanofiltration membrane was prepared by embedding various concentrations of the modified Fe3O4 based nanoparticles. The membranes were characterized in terms of morphology and performance including investigation of SEM and AFM microphotographs, water contact angle, mean pore size and porosity measurements and determination of pure water flux as well as copper ion removal. Embedding iron oxide nanoparticles resulted in a significant rise in the pure water flux as a result of changes in the mean pore radius, porosity and hydrophilicity of the membranes. Moreover, the copper removal capability of prepared membranes remarkably increased because of improved hydrophilicity and also presence of nucleophilic functional groups on nanoparticles. The membrane fabricated with 0.1 wt.% metformine-modified silica coated Fe3O4 nanoparticles showed the highest copper removal (about 92%) due to high affinity in copper adsorption. Moreover, acceptable reusability was found for the membrane with the best performance after several times of usage/regeneration cycles usin EDTA as eluting agent.

description: Consumers are increasingly interested in farming methods and the nutritional quality of food. Manufacturers, in turn, are adding more information to food labels. In 1990, Congress passed two watershed laws on food labeling, one requiring nutrition labels to be included on most processed foods and the other requiring organic foods to meet a national uniform standard. This report examines the economic issues involved in five labels for which the Federal Government has played different roles in securing the information and making it transparent to consumers. In addition to the nutrition and organic labels, the report scrutinizes three other labels—one advertising foods made without genetically engineered ingredients, another advertising products made from animals raised without antibiotics, and the Federal country-of-origin label, which is now required for fresh and frozen fruits and vegetables, some nuts, fish and shellfish, ginseng, and certain meats. As interest grows in process-based and other types of food labeling, findings from these five case studies illustrate the economic effects and tradeoffs in setting product standards, verifying claims, and enforcing truthfulness.

description: Vacuum Brans-Dicke theory can be self-consistently described in two frames, the Jordan frame (JF) and the conformally rescaled Einstein frame (EF), the transformations providing an easy passage from one frame to the other at the level of actions and solutions. Despite this, the conformal frames are inequivalent describing different geometries. It is shown that the predictions of the weak field lensing (WFL) observables in the EF are different from those recently obtained in the JF for the vacuum Brans-Dicke class 1 solution. The value of the Brans-Dicke coupling parameter $ω$ from the Cassini spacecraft experiment reveals the degree of accuracy needed to experimentally distinguish the WFL measurements including the total magnification factor in the two frames.

description: This article presents a radio frequency system that can be used to perform precise vertical landings of drones. The system is based on the three-way phase shift detection of a signal transmitted from the landing point. The antenna system is designed by taking into account parameters such as landing tracking area, analog-to-digital converter (ADC) resolution, phase detector output range, antenna polarization, and the effect of antenna axial ratio. The fabricated prototype consists of a landing point antenna that transmits a signal at 2.46 GHz, as well as a drone triantenna system that includes a phase shift detection circuitry, ADC, and a simple control program that provides the correction instructions for landing. The prototype provides an averaged output data rate (ODR) suitable for landing maneuvers (>300 Hz). A simple system calibration procedure (detector output zeroing) is performed by aligning the antenna system. The measurements performed at different altitudes demonstrate both the correct operation of the proposed solution and its viability as an instrument for precision vertical landings.

description: The improvement in Information Technology has encouraged the use of Igbo in the creation of text such as resources and news articles online. Text similarity is of great importance in any text-based applications. This paper presents a comparative analysis of n-gram text representation on Igbo text document similarity. It adopted Euclidean similarity measure to determine the similarities between Igbo text documents represented with two word-based n-gram text representation (unigram and bigram) models. The evaluation of the similarity measure is based on the adopted text representation models. The model is designed with Object-Oriented Methodology and implemented with Python programming language with tools from Natural Language Toolkits (NLTK). The result shows that unigram represented text has highest distance values whereas bigram has the lowest corresponding distance values. The lower the distance value, the more similar the two documents and better the quality of the model when used for a task that requires similarity measure. The similarity of two documents increases as the distance value moves down to zero (0). Ideally, the result analyzed revealed that Igbo text document similarity measured on bigram represented text gives accurate similarity result. This will give better, effective and accurate result when used for tasks such as text classification, clustering and ranking on Igbo text.

description: It is a major research topic of limited generalized linear models, namely, generalized linear models with limited dependent variables. The models are developed in many research fields. However, quasi-likelihood estimation of the models is an unresolved issue, due to including limited dependent variables. We propose a novel quasi-likelihood, called Taylor quasi-likelihood, to handle with the unified estimation problem of the limited models. It is based on Taylor expansion of distribution function or likelihood function. We also extend the likelihood to a generalized version and an adaptive version and propose a distributed procedure to obtain the likelihood estimator. In low-dimensional setting, we give selection criteria for the proposed method and make arguments for the consistency and asymptotic normality of the estimator. In high-dimensional setting, we discuss feature selection and oracle properties of the proposed method. Simulation results confirm the advantages of the proposed method.
The Island and the Ocean : The Preservation of Intangible Heritage In Outport Newfoundland
Creators: name: Oke, Kathy
Publisher: name: The University of British Columbia
Year: 2019

description: The Island and the Ocean is an architectural graduation project set in rural Newfoundland, which aims to answer the question of how architecture might restore agency to a draining population, and reconnect the culture, identity, and future of the island to contemporary Newfoundlanders. It is a critique of the tourist-centric model of cultural heritage preservation that is prevalent across rural North America. It is a proposal for an alternative framing of preservation which prioritizes the evolution of culture over time. The project proposes that it is possible to design local tradition and inherited knowledge into architecture not just formally, but at the level of its function, social and spatial systems, and organization. Beyond this, by collecting and integrating programming which reflects the local culture in a way that encourages participation through creative practices, a building can become a catalyst for the sharing of heritage, community, and cultural rejuvenation. This thesis tests how – beside protection of the architectural object – architecture can look beyond the literal built form to the processes and sociospatial systems around which a place has developed as a means to create locally legible social infrastructure within which a new restorative ritual of cultural heritage preservation can take place.

description: Supermassive binary black holes at sub-parsec orbital separations have yet to be discovered, with the possible exception of blazar OJ~287. In parallel to the global hunt for nanohertz gravitational waves from supermassive binaries using pulsar timing arrays, there has been a growing sample of candidates reported from electromagnetic surveys, particularly searches for periodic variations in optical light curves of quasars. However, the periodicity search is prone to false positives from quasar red noise and quasi-periodic oscillations from the accretion disc of a single supermassive black hole---especially when the data span fewer than a few signal cycles. We present a Bayesian method for the detection of quasar (quasi-)periodicity in the presence of red noise. We apply this method to the binary candidate PG1302$-$102, and show that a) there is very strong support (Bayes factor $>10^6$) for quasi-periodicity, and b) the data slightly favour a quasi-periodic oscillation over a sinusoidal signal, which we interpret as modest evidence against the binary black hole hypothesis. We also find that the prevalent damped random walk red-noise model is disfavored with more than 99.9\% credibility. Finally, we outline future work that may enable the unambiguous identification of supermassive binary black holes.

description: We review the status of nu_mu-->nu_tau flavor transitions of atmospheric neutrinos in the 92 kton-year data sample collected in the first phase of the Super-Kamiokande (SK) experiment, in combination with the recent spectral data from the KEK-to-Kamioka (K2K) accelerator experiment (including 29 single-ring muon events). We consider a theoretical framework which embeds flavor oscillations plus hypothetical decoherence effects, and where both standard oscillations and pure decoherence represent limiting cases. It is found that standard oscillations provide the best description of the SK+K2K data, and that the associated mass-mixing parameters are determined at 1 sigma (and d.o.f.=1) as: Delta m^2=(2.6 +- 0.4)x10^{-3} eV^2 and sin^2(2theta)=1.00+0.00-0.05. As compared with standard oscillations, the case of pure decoherence is disfavored, although it cannot be ruled out yet. In the general case, additional decoherence effects in the nu_mu-->nu_tau channel do not improve the fit to the SK and K2K data, and upper bounds can be placed on the associated decoherence parameter. Such indications, presently dominated by SK, could be strengthened by further K2K data, provided that the current spectral features are confirmed with higher statistics. A detailed description of the statistical analysis of SK and K2K data is also given, using the so-called ``pull'' approach to systematic uncertainties.

description: While there has been considerable research on the analysis of extreme values and outliers by using heavy-tailed distributions, little is known about the semi-heavy-tailed behaviors of data when there are a few suspicious outliers. To address the situation where data are skewed possessing semi-heavy tails, we introduce two new skewed distribution families of the hyperbolic secant with exciting properties. We extend the semi-heavy-tailedness property of data to a linear regression model. In particular, we investigate the asymptotic properties of the ML estimators of the regression parameters when the error term has a semi-heavy-tailed distribution. We conduct simulation studies comparing the ML estimators of the regression parameters under various assumptions for the distribution of the error term. We also provide three real examples to show the priority of the semi-heavy-tailedness of the error term comparing to heavy-tailedness. Online supplementary materials for this article are available. All the new proposed models in this work are implemented by the shs R package, which can be found on the GitHub webpage.

Characterization of the catalyst was performed with various physicochemical methods. This effective catalyst was evaluated in terms of activity and reusability. It indicated high catalytic activity, good recoverability and reusability, and supplied the corresponding products in high yields and short reaction times. In addition, it shows notable advantages such as simplicity of operation, heterogeneous nature, easy work up, and it could be used at least eight times with no significant loss of its activity.

description: An estimated 87.7 percent of American households were food secure throughout the entire year in 2016, meaning they had access at all times to enough food for an active, healthy life for all household members. The remaining households (12.3 percent) were food insecure at least some time during the year, including 4.9 percent with very low food security, meaning that at times the food intake of one or more household members was reduced and their eating patterns were disrupted because the household lacked money and other resources for obtaining food. Changes from 2015 to 2016 in food insecurity overall (from 12.7 to 12.3 percent) and in very low food security (from 5.0 to 4.9 percent) were not statistically significant, but they continued a downward trend in food insecurity from a high of 14.9 percent in 2011. Among children, changes from 2015 in food insecurity and very low food security were also not statistically significant. Children and adults were food insecure in 8.0 percent of households with children in 2016, essentially unchanged from 7.8 percent in 2015. Very low food security among children was 0.8 percent in 2016, essentially unchanged from 0.7 percent in 2015. In 2016, the typical food-secure household spent 29 percent more on food than the typical food-insecure household of the same size and household composition. About 59 percent of food-insecure households participated in one or more of the three largest Federal food and nutrition assistance programs during the month prior to the 2016 survey (food stamps (SNAP); Special Supplemental Nutrition Program for Women, Infants, and Children (WIC); and the National School Lunch Program).

description: The evolution of the solar wind electron distribution function with heliocentric distance exhibits different features that are still unexplained, in particular, the increase of the Strahl pitch angle width. Wave-particle interactions between electrons and whistler waves are often proposed to explain these phenomena. We aim at quantifying the effect of whistler waves on suprathermal electrons as a function of heliocentric distance. We first perform a statistical analysis of whistler waves (occurrence and properties) observed by Solar Orbiter and Parker Solar Probe between 0.2 and 1 AU. The wave characteristics are then used to compute the diffusion coefficients in the framework of quasi-linear theory. These coefficients are integrated in order to deduce the overall effect of whistler waves on electrons along their propagation. 110,000 whistler wave packets are detected and characterized in the plasma frame. Most waves are aligned with the magnetic field and only about 0.5% of them have a propagation angle greater than 45°. Beyond 0.3 AU, almost exclusively anti-sunward waves (some of them are found sunward but are within switchbacks with a change of sign of the radial component of the background magnetic) are observed. These waves are therefore Strahl-aligned and not counter-streaming. At 0.2 AU we find both Strahl-aligned and counter-streaming waves. Beyond 0.3 AU, the integrated diffusion coefficients show that the observed waves can explain the measured Strahl pitch angle evolution and are effective in isotropizing the halo. Strahl diffusion is mainly due to whistler waves with an angle of propagation between 15° and 45°. Near 0.2 AU, counter-streaming whistler waves can diffuse the Strahl electrons more efficiently than the Strahl-aligned waves by two orders of magnitude.

description: We investigate the impact of a highly eccentric 10 $M_{\rm \oplus}$ (where $M_{\rm \oplus}$ is the Earth mass) planet embedded in a dusty protoplanetary disk on the dust dynamics and its observational implications. By carrying out high-resolution 2D gas and dust two-fluid hydrodynamical simulations, we find that the planet's orbit can be circularized at large radii. After the planet's orbit is circularized, partial gap opening and dust ring formation happen close to the planet's circularization radius, which can explain the observed gaps/rings at the outer region of disks. When the disk mass and viscosity become low, we find that an eccentric planet can even open gaps and produce dust rings close to the pericenter and apocenter radii before its circularization. This offers alternative scenarios for explaining the observed dust rings and gaps in protoplanetary disks. A lower disk viscosity is favored to produce brighter rings in observations. An eccentric planet can also potentially slow down the dust radial drift in the outer region of the disk when the disk viscosity is low ($α\lesssim2\times10^{-4}$) and the circularization is faster than the dust radial drift.

description: Αντικείμενο της παρούσας μεταπτυχιακής διπλωματικής εργασίας αποτελεί η μελέτη του ποιητικού και του στιχουργικού έργου του Μάνου Ελευθερίου, με σκοπό την ανάδειξη των κυρίαρχων θεμάτων και θεματικών του μοτίβων. Η πορεία που διέγραψε στα γράμματα ο συριανός δημιουργός ήταν μακρά, καλύπτοντας ένα χρονικό άνυσμα πέραν των πενήντα ετών, σε μία ιδιαιτέρως ταραχώδη και επεισοδιακή περίοδο της νεοελληνικής ιστορίας, η οποία τον σημάδεψε καθοριστικά τόσο ως προσωπικότητα όσο και ως λογοτέχνη. Στην εργασία αυτή εξετάζονται οι βασικότεροι θεματικοί πυλώνες επί των οποίων δομείται το έργο του Ελευθερίου, οι οποίοι τέμνονται σαφώς σε αρκετά σημεία, εντούτοις αποτελούν αυτόνομα τμήματα της ιδεολογίας του όπως αυτή εκφράστηκε μέσα από το έργο του. Τα ενδιαφέροντα και οι ανησυχίες του δημιουργού μπορούν να συνοψιστούν στις εξής θεματικές ενότητες: τον πολιτικό στοχασμό, την κοινωνική παρατήρηση και κριτική, τις αναζητήσεις του σχετικά με την ανθρώπινη ύπαρξη, και, τέλος, τις απόψεις του αναφορικά με τη λογοτεχνία, καθώς και τη σχέση που ανέπτυξε με αυτήν ως συγγραφέας. Μέσα από αυτές τις ευρύτερες ενότητες μελετούνται ποικίλοι προβληματισμοί του Ελευθερίου και σκιαγραφείται το ιδεολογικό προφίλ του συριανού λογοτέχνη. Παράλληλα, ανιχνεύεται ο τρόπος με τον οποίον διαχειρίστηκε τα δυο αυτά είδη λόγου, την ποίηση και την στιχουργική, και οδηγούμαστε σε ορισμένα συμπεράσματα σχετικά με τα κοινα αλλά και τα αποκλίνοντα χαρακτηριστικά τους
description: This dissertation set out to explore Manos Eleftheriou’s work, focusing specifically on his poems and lyrics aiming to highlight the main themes and thematic patterns of his work. As Manos Eleftheriou was literary active for about half a century, he witnessed a long series of political and social events which affected his ideology and his way of thinking both as a man and as a writer. This dissertation identifies the main themes of Eleftheriou’s poems and lyrics and summarizes them in four wide thematic categories: his political beliefs, his opinions about social matters, his thoughts about human existence and his way of perceiving literature. From within those thematic categories several of Eleftheriou’s reflections are being examined which help us understand his ideology and way of understanding the world. Lastly, this paper focuses on the points of convergence and deviation detected between the two types of literary writing, poetry and versification

description: Principal component regression uses principal components (PCs) as regressors. It is particularly useful in prediction settings with high-dimensional covariates. The existing literature treating of Bayesian approaches is relatively sparse. We introduce a Bayesian approach that is robust to outliers in both the dependent variable and the covariates. Outliers can be thought of as observations that are not in line with the general trend. The proposed approach automatically penalises these observations so that their impact on the posterior gradually vanishes as they move further and further away from the general trend, corresponding to a concept in Bayesian statistics called whole robustness. The predictions produced are thus consistent with the bulk of the data. The approach also exploits the geometry of PCs to efficiently identify those that are significant. Individual predictions obtained from the resulting models are consolidated according to model-averaging mechanisms to account for model uncertainty. The approach is evaluated on real data and compared to its nonrobust Bayesian counterpart, the traditional frequentist approach and a commonly employed robust frequentist method. Detailed guidelines to automate the entire statistical procedure are provided. All required code is made available, see ArXiv:1711.06341.

description: The commercial fishery is an industry of relative importance in the United States. In 1976, landings by U.S. vessels at U.S. ports amounted to 5.4 billion pounds and were valued at 1.4 billion dollars (figure 1). In spite of the economic significance of the industry, only recently has any notable national policy been developed which addresses itself to the problem of managing marine fishery resources.

description: The aim of the present thesis is to analyze the legal issue of the beginning and end of military occupation under international law. In the first chapter, we refer to the evolution of the notion of military occupation as well as its legal frame. In the second chapter, we present the conditions which must be fulfilled, in order to define the beginning of military occupation. Special emphasis is laid on the notion of effective control. Through the survey of rules of international law, jurisprudence of international institutions and reports of international organizations, we examine the degree and form of control, which are necessary for the military occupation to begin. In the third chapter, we analyze the means through which military occupation can be ended with special reference to the cases of Gaza Strip and Iraq. In the fourth chapter we analyze the case of prolonged military occupation. Finally, we present the conclusions drawn through the present thesis

description: Photoluminescence spectra have been investigated in erbium doped GaLaS(O) glasses. The samples demonstrate intense green emission bands centered at around 525 and 550 nm due to up-conversion processes in erbium ions. The theoretical description of up-conversion intensity as a function of excitation intensity has been offered. It is based on a solution of a system of rate equations taking into account three up-conversion transitions.
