Iterated and irreducible pion-photon exchange in nuclei
Creators: name: Kaiser, N.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: We calculate the contribution to the nuclear energy density functional which arises from iterated pion-photon exchange between nucleons. In heavy nuclei, this novel charge symmetry breaking interaction leads to an additional binding of each proton by about 0.2 MeV. Compared to that the analogous effect from irreducible pion-photon exchange is negligibly small. As a possible mechanism to resolve the Nolen-Schiffer anomaly we propose the iteration of one-photon exchange with an attractive short-range NN-interaction. The corresponding energy per proton reads: $\bar E[ρ_p]=(2α/15π^2)(π^2 -3+6 \ln2) {\cal A}_{pp} k_p^2$ with $ρ_p =k_p^3/ 3π^2$ the proton density and ${\cal A}_{pp}\approx 2 $fm an effective (in-medium) scattering length. Hints for such a value of ${\cal A}_{pp}$ come from phenomenological Skyrme forces and from the neutron matter equation of state.

Higher Education in Urban Forestry in North America and Europe: Profiling Skills and Competencies for the Labor Market of Today and Tomorrow
Creators: name: Baumeister, Christoph Florian
Publisher: name: The University of British Columbia
Year: 2014

description: Higher education in urban forestry is fragmented, encompassing multiple disciplines. The same is true for the fields of occupation—professionals in urban forestry work in a multi-faceted labor market. Little research has been done to describe what higher education in urban forestry looks like and what the fields of employment in the urban forestry sector are. Furthermore, there is a lack of knowledge with respect to skills and competencies professionals should have to manage, create and design urban woodlands. Using a descriptive methodology, this study identified higher institutions in urban forestry and fields of employment by analyzing labor statistics as well as books, journals and webpages. Additionally, I used multiple approaches to profile needed skills and competencies: job descriptions, opinions of practitioners and employers were used to give voice to the labor market. Existing urban forest management plans were scanned for components. I have examined research topics, opinions of educators of higher urban forestry institutions, as well as visions of cities to predict competencies needed for the labor market of tomorrow. The results indicate that growing urbanization and public demand on urban greenspaces call for new professionals, who must unify, expand and redefine existing established disciplines. Finally, they should be able to identify cities’ challenges, develop solutions and should know the vital contribution of urban greenspaces to livable green cities of tomorrow.

description: Food away from home (FAFH) has become increasingly integral to the American diet. In 2010, the share of Americans’ food budget for FAFH—reaching 50 percent (up from 41 percent in 1984)—surpassed the share for food at home (FAH) for the first time. Likewise, Americans’ share of energy intake from FAFH rose from 17 percent in 1977-78 to 34 percent in 2011-12, with differences in growth across types of FAFH (e.g., full- and quick-service restaurant foods, school meals, etc.). Along with the demand for FAFH, availability of FAFH has also increased, with much of the growth in recent years attributable to quick-service restaurants. The growing presence of FAFH in Americans’ diets reflects changes in consumer demand and producer behavior and affects the health and nutrition of individuals over time. This report takes a comprehensive look at the role of FAFH in American diets, exploring nutritional composition of FAFH and key Federal programs that may influence FAFH. The report also discusses how FAFH choices and availability relate to diet quality, income, age, and other socioeconomic factors.

description: The existence of star-to-star light-element abundance variations (multiple populations, MPs) in massive Galactic and extragalactic star clusters older than about 2 Gyr is by now well established. Photometry of red giant branch (RGB) stars has been and still is instrumental in enabling the detection and characterization of cluster MPs, through the appropriate choices of filters, colours and colour combinations, that are mainly sensitive to N and --to a lesser degree-- C stellar surface abundances. An important issue not yet properly addressed is that the translation of the observed widths of the cluster RGBs to abundance spreads must account for the effect of the first dredge-up on the surface chemical patterns, hence on the spectral energy distributions of stars belonging to the various MPs. We have filled this gap by studying theoretically the impact of the dredge-up on the predicted widths of RGBs in clusters hosting MPs. We find that for a given initial range of N abundances, the first dredge up reduces the predicted RGB widths in N-sensitive filters compared to the case when its effect on the stellar spectral energy distributions is not accounted for. This reduction is a strong function of age and has also a dependence on metallicity. The net effect is an underestimate of the initial N-abundance ranges from RGB photometry if the first dredge-up is not accounted for in the modelling, and also the potential determination of spurious trends of N-abundance spreads with age.

The results provide a nationwide and small scale (in a 250 m x 250 m grid) picture about school accessibility in Germany below the administrative level of the communities. As such the data allow to identify regions in Germany with already suboptimal school accessibility and re-gions where future school closures are going to intensify the present situation.

The analysis leads to following overall conclusion: At present all analyzed schools are good acces-sible by car. That is within a travel time of 30 minutes. By bicycle in great parts of Germany pri-mary schools and schools with Sekundarstufe 1 are accessible. That is within a travel time of 15 minutes 91 % of the population can reach a primary school by bicycle and 77 % of the population a school with Sekundarstufe 1. However, in large parts of the rural areas by foot school are bad accessible.

description: In this article, we examine prediction in the context of linear index models when one or more of the regressors are endogenous. To facilitate both within-sample and out-of-sample predictions, Stata offers the postestimation command predict (see [R] predict). We believe that the usefulness of the predictions provided by this command is limited, especially if one is interested in out-of-sample predictions. We demonstrate our point using a probit model with continuous endogenous regressors, although it clearly generalizes readily to other linear index models. We subsequently provide a program that offers one possible implementation of a new command, ivpredict, that can be used to address this shortcoming of predict, and we then illustrate its use with an empirical example.

description: This study extends the literature on interfuel substitution by investigating the role of transactions costs and technological adjustment, focusing specifically on differences across countries with different potential for fossil fuel production. We find that fossil fuel producing economies have higher elasticities of interfuel substitution. Our simulations show that, compared to the baseline case of uniform elasticities, energy and climate policies result in a greater substitution among different sources of energy for countries with larger potential to produce fossil fuels. These results are important because they imply lower economic cost for policies aimed at climate abatement and more efficient utilization of energy resources in energy-intensive economies.

We calculate the distribution functions of the time averaged intensity correlation function and show that these distributions are not delta peaked on the ensemble average correlation function values; instead they are W or U shaped. Beyond blinking nano-crystals our results describe non-ergodicity in systems stochastically modeled using the Levy walk framework for anomalous diffusion, for example certain types of chaotic dynamics, currents in ion-channel, and single spin dynamics to name a few.

description: The prevalence of undocumented workers in the United States is a sensitive issue for U.S. policy makers with numerous policy responses contemplated by several different administrations. This paper examines the impact of possible reforms to U.S. immigration policy with respect to undocumented workers on the U.S. and Mexican economies. Using a global trade and migration model that considers undocumented workers, we find that undocumented workers have a positive impact on the U.S. economy and on the agricultural sector. Legalization of these undocumented workers emerges as the preferred option, although additional considerations may be required to assist the agricultural sector.

description: In an attempt to control the flow of undocumented immigrants, successive US governments have considered everything from large scale deportation, amnesties, expanding visa programs, to fining firms who hire illegal workers. Using a comparative static model, Aguiar and Walmsley (2013), find that amnesties have a positive impact on the US economy. However such policies are one-time changes in the labor force, whose benefits diminish over time, and which are unlikely to stem the flow of undocumented workers or fulfill the demands of U.S. firms for cheap foreign labor. In this paper we use a global dynamic model to investigate the long run implications of three alternative policy scenarios: 1) a one-time amnesty for undocumented workers living in the US; 2) a permanent increase in the number of foreign worker visas; and 3) enhanced border security. We find that an amnesty is much less effective than a permanent increase in visas at promoting growth in the U.S., while enhanced border control by the U.S. is beneficial for Mexico in terms real GDP.

description: The GTAP Data Base provides a consistent snapshot of the global economy. It consists of a set of product-by-industry input output tables that represent the structures of more than 100 economies and are linked by bilateral merchandise and cross-border services trade. It is used to support a variety of models that are built to analyse policy changes. The database is assembled using regional input-output tables and data on trade, energy, protection and macroeconomic aggregates from a variety of international sources. The incompatibilities inherent in the data mean that many compromises are required to produce a fully consistent representation of the global economy. This paper provides a summary of the GTAP Data Base construction process. The process has improved continuously over the different versions. This paper refers to the process used to produce version 8.1. The detailed documentation is available from https://www.gtap.agecon.purdue.edu/databases/v8/v8_doco.asp. The purpose of this paper is to provide a link between that detailed documentation and the higher-level summary in the "Introduction to the Global Trade Analysis Project and the GTAP Data Base" paper by Walmsley, Aguiar and Narayanan (2012). This paper contains three sections. Section 1 provides an overview of the GTAP Data Base construction procedure. Section 2 details the data sources used and the manipulations applied to data obtained from international organizations to ensure that they are globally consistent. Section 3 details the FIT process, which is the procedure used to adjust regional I-O tables so that they are consistent with international data sources.

description: The general kind noncanonical warm inflation is introduced and its total non-Gaussianity of perturbation on uniform energy density hypersurfaces is studied. The total non-Gaussianity contains two complementary parts: the three- and the four-point correlations. The three-point correlation part denoted by $f^{int}_{NL}$, comes from the three-point correlation of inflaton field, while the four-point correlation part, denoted by $f_{NL}^{δN}$, is the contribution due to the four-point correlation function of the inflaton field. The aforementioned two parts of non-Gaussianity in general noncanonical warm inflation are calculated and analysed respectively, and the comparisons and discussions of the two parts are finally carried out in this study.

This scheme allows for an analysis of the structure of the solution in the vicinity of bifurcation points along the Maclaurin sequence. The post-Newtonian expansion is solved explicitly to the fourth order and its accuracy and convergence are studied by comparing it to highly accurate numerical results.

description: The problem of finding the densest subgraph in a given graph has several applications in graph mining, particularly in areas like social network analysis, protein and gene analyses etc. Depending on the application, finding dense subgraphs can be used to determine regions of high importance, similar characteristics or enhanced interaction. The densest subgraph extraction problem is a fundamentally a non-linear optimization problem. Nevertheless, it can be solved in polynomial time by an exact algorithm based on the iterative solution of a series of maximum flow sub-problems. Despite its polynomial time complexity, the computing time required by the exact algorithms on very large graphs could be prohibitive. Thus, to approach graphs with millions of vertices and edges, one has to resort to heuristic algorithms. We provide an efficient implementation of a greedy heuristic from the literature that is extremely fast and has some nice theoretical properties. We also introduce a new heurisitic algorithm that is built on top of the greedy and the exact methods. An extensive computational study is presented to evaluate the performance of various solution methods on a benchmark composed of 86 instances taken from the literature. This analysis shows that the proposed heuristic algorithm proved very effective on a large number of test instances, often providing either the optimal solution or near-optimal solution within short computing times.

Πιο συγκεκριμένα, σκοπός είναι η διερεύνηση της θετικής συσχέτισης της αυτο-αποτελεσματικότητας των εκπαιδευτικών με τη δημιουργικότητα, την εργασιακή ικανοποίηση και την εργασιακή τους προσήλωση, αναμένοντας ότι υπηρεσίες εκπαίδευσης που παρέχονται από τις εκπαιδευτικές μονάδες στο δημόσιο και στον ιδιωτικό τομέα θα βελτιωθούν. Όλες οι απαραίτητες πληροφορίες αποκτήθηκαν από ερωτηματολόγιο που συμπληρώθηκε από 117 εκπαιδευτικούς διαφορετικών πεδίων που εργάζονται στην πρωτοβάθμια και δευτεροβάθμια εκπαίδευση, σε δημόσια και ιδιωτικά σχολεία και σε φροντιστήρια σε όλη την Ελλάδα. Τα αποτελέσματα της έρευνας φαίνεται να επιβεβαιώνουν τις υποθέσεις, καθώς η αυτο-αποτελεσματικότητα των εκπαιδευτικών σχετίζεται θετικά με τη δημιουργικότητα, την εργασιακή ικανοποίηση και την εργασιακή προσήλωση. Επιπλέον, γίνονται κάποιες προτάσεις που αφορούν τους εκπαιδευτικούς οργανισμούς, ώστε να υπογραμμιστεί η σπουδαιότητα της αύξησης της αυτο-αποτελεσματικότητας των εκπαιδευτικών. Η αυτο-αποτελεσματικότητα αποτελεί έναν βασικό παράγοντα που οι οργανισμοί θα έπρεπε να λαμβάνουν υπόψη αν επιθυμούν να ευημερούν.

description: The present master’s thesis examines the positive outcomes of teachers' self-efficacy to their attitudes and behaviours. To be more specific, the aim is to investigate the positive correlation of teachers' self-efficacy with their creativity, job satisfaction and work engagement, expecting that the educational services provided by the educational units in the public and private sector will improve. All the necessary information was obtained from a questionnaire completed by 117 teachers of different fields working in primary and secondary education, in public and private schools and in private educational organisations throughout Greece. The findings of the study seem to confirm the hypotheses, since teachers' self-efficacy is positively related to creativity, job satisfaction and work engagement. In addition, some suggestions concerning the educational organisations are made, in order for the significance of increasing teachers' self-efficacy to be highlighted. Self-efficacy is a key factor that organisations should take into consideration if they wish to thrive. The last part of the study consists of suggestions for future research and the limitations of the research as well.

description: The GTAP standard model has proved a useful analysis tool and data source for over 20 years. The GTAP model has been updated overtime, but it maintains the structure of a single regional household, with income distributed into three components: government, private and savings-investment expenditures. There has been a need for a more detailed accounting system, especially as it relates to estimating the potential impacts of policies and global shocks on poverty, sustainable and inclusive growth. This paper presents an extension to the GTAP model and its accounting framework to implement distinct and multiple households, split factors of production, foreign aid and remittances, government and household transfer. The model and associated accounting links a household's expenditure to factor incomes (through ownership shares) and taxes. Government expenditure is linked to taxes and foreign aid. The MyGTAP model provides the user more flexibility in: the treatment of government and household savings and spending; the selection of a linear expenditure systems (LES) or a constant difference of elasticities (CDE) demand function\s. The model is incorporated into a RunGTAP application which supports many of RunGTAP's popular programs such as alter-tax, GTAPview and others. The introduction of a split regional household (which does not require splitting data for every region) supports economic analysis based on detailed households, government, factor income, remittances, foreign aid and income transfers. The code can be modified to include multiple regions with unique household structures.

description: We determine the precise asymptotic behaviour (in space) of the Green kernel of simple random walk with drift on the Diestel-Leader graph $DL(q,r)$, where $q,r \ge 2$. The latter is the horocyclic product of two homogeneous trees with respective degrees $q+1$ and $r+1$. When $q=r$, it is the Cayley graph of the wreath product (lamplighter group) ${\mathbb Z}_q \wr {\mathbb Z}$ with respect to a natural set of generators. We describe the full Martin compactification of these random walks on $DL$-graphs and, in particular, lamplighter groups. This completes and provides a better approach to previous results of Woess, who has determined all minimal positive harmonic functions.

Creators: name: Li, Carol
Publisher: name: The University of British Columbia
Year: 2014

description: This term project paper aims to find a guiding theoretical framework for gamification in workplace IS context and then evaluate the corresponding model using what we have learned in class. The impact of games and gamified elements on modern world, especially on the working environment was explored in order to answer the question 'exactly what can gamification offer to employees?' and a literature review was conducted. A model proposed by Herzig on workplace IS gamification was then evaluated and certain modification was suggested based on the discussion in the paper.

description: The concept of extended Hamiltonian systems allows the geometrical interpretation of several integrable and superintegrable systems with polynomial first integrals of degree depending on a rational parameter. Until now, the procedure of extension has been applied only in the case of natural Hamiltonians. In this article, we give several examples of application to non-natural Hamiltonians, such as the two point-vortices, the Lotka-Volterra and some quartic in the momenta Hamiltonians, obtaining effectively extended Hamiltonians in some cases and failing in others. We briefly discuss the reasons of these results.

description: A cluster is a group of computers that are linked together to form a single system. A commodity cluster uses “off-the-shelf”, conventional, pc server hardware. Clusters are used to solve or model large complex problems which would otherwise be difficult or impossible to run on current high specification computers. There is a wide range of available tools that can be used to manage clusters; these include open source tools as well as commercial ones. We carried out a review of the most commonly used cluster management tools, considering areas such as functionality, ease of use, and installation. Finally we drew some conclusions about their relative merits.

description: Deep neural networks are generally designed as a stack of differentiable layers, in which a prediction is obtained only after running the full stack. Recently, some contributions have proposed techniques to endow the networks with early exits, allowing to obtain predictions at intermediate points of the stack. These multi-output networks have a number of advantages, including: (i) significant reductions of the inference time, (ii) reduced tendency to overfitting and vanishing gradients, and (iii) capability of being distributed over multi-tier computation platforms. In addition, they connect to the wider themes of biological plausibility and layered cognitive reasoning. In this paper, we provide a comprehensive introduction to this family of neural networks, by describing in a unified fashion the way these architectures can be designed, trained, and actually deployed in time-constrained scenarios. We also describe in-depth their application scenarios in 5G and Fog computing environments, as long as some of the open research questions connected to them.

description: La Colección de Folklore reunida en Argentina en 1921 constituye un monumental archivo de manifestaciones culturales entre las que se encuentra una valiosa colección de temas y versiones romancísticas. Ismael Moya en su Romancero de 1941 publicó una selección de los romances documentados en la Colección, pero distintas falencias de orden teórico y metodológico presentes en el libro invitan a una revisión crítica de sus contenidos. En la presente ponencia propongo una nueva mirada sobre este corpus de romances que todavía espera su edición definitiva.

description: Cathodoluminescence (CL) has evolved into a standard analytical technique in (scanning) transmission electron microscopy. CL utilizes light excited due to the interactions between the electron-beam and the sample. In the present study we focus on Cerenkov radiation. We make use of the fact that the electron transparent specimen acts as a Fabry-Pérot interferometer for coherently emitted radiation. From the wavelength dependent interference pattern of thickness dependent measurements we calculate the refractive index of the studied material. We describe the limits of this approach and compare it with the determination of the refractive index by using valence electron energy loss spectrometry (VEELS)

description: GRANDMA is a network of 25 telescopes of different sizes, including both photometric and spectroscopic facilities. The network aims to coordinate follow-up observations of gravitational-wave candidate alerts, especially those with large localisation uncertainties, to reduce the delay between the initial detection and the optical confirmation. In this paper, we detail GRANDMA's observational performance during Advanced LIGO/Advanced Virgo Observing Run 3 (O3), focusing on the second part of O3; this includes summary statistics pertaining to coverage and possible astrophysical origin of the candidates. To do so, we quantify our observation efficiency in terms of delay between gravitational-wave candidate trigger time, observations, and the total coverage. Using an optimised and robust coordination system, GRANDMA followed-up about 90 % of the gravitational-wave candidate alerts, i.e. 49 out of 56 candidates. This led to coverage of over 9000 deg2 during O3. The delay between the gravitational-wave candidate trigger and the first observation was below 1.5 hour for 50 % of the alerts. We did not detect any electromagnetic counterparts to the gravitational-wave candidates during O3, likely due to the very large localisation areas (on average thousands of degrees squares) and relatively large distance of the candidates (above 200 Mpc for 60 % of BNS candidates). We derive constraints on potential kilonova properties for two potential binary neutron star coalescences (GW190425 and S200213t), assuming that the events' locations were imaged.

description: Ο ανατολικός πλάτανος αποτελεί ένα είδος που πλειοψηφεί μεταξύ των μνημείων της φύσης ως άξιο προστασίας για εθνικούς σκοπούς. Το συγκεκριμένο δέντρο, λόγω των ιστοριών που του αποδίδεται, αποτελεί σύμφωνα με ερευνητές, ένα εργαλείο ανασυγκρότησης θρησκευτικών και εθνικών αναμνήσεων. Η ξεχωριστή θέση που κατέχει στην ελληνική παράδοση, θα μπορούσε σε αυτό το πλαίσιο να αξιοποιηθεί για την ανάδειξη περιοχών της ηπειρωτικής Ελλάδας που πιθανόν να βρίσκονται μακριά από δημοφιλή τουριστικά κέντρα. Η εθνοικολογία, είναι η διαπολιτισμική μελέτη του τρόπου με τον οποίο οι άνθρωποι αντιλαμβάνονται και χειραγωγούν το περιβάλλον τους. Υπό το πρίσμα αυτό η παρούσα έρευνα χαρτογραφεί την εξάπλωση των πλατάνων στα κέντρα – πλατείες των ελληνικών οικισμών της περιφέρειας Ανατολικής Μακεδονίας και Θράκης. Σκοπός της εργασίας είναι να συσχετίσει την ύπαρξή των πλατάνων με σταθμικές ή πολιτιστικές μεταβλητές. Τέλος η έρευνα στοχεύει στην χρήση των αποτελεσμάτων ως βάση για τη δημιουργία ενός νέου συμβόλου της ελληνικής παράδοσης που θα μπορούσε να αξιοποιηθεί για την προσέλκυση επισκεπτών σε μη ευνοημένες περιοχές.
description: The oriental plane tree is a species worthy of protection for national purposes in Greece. This particular tree, due to the stories attributed to it, is according to researchers, a precious tool for reconstructing memories associated to culture and religion. The special place that holds within the Greek traditions, could be used to highlight areas of mainland Greece that may be located away from popular tourist centers. Ethnoecology is an interdisciplinary study of the way in which people perceive and manipulate their environment - and in this context, the present study attempts to map the geographical distribution of plane trees among villages within the region of Eastern Macedonia and Thrace. The aim of this study is to correlate the existence of plane trees with natural or cultural variables. Finally, the research aims to use the results as a basis for creating a potential touristic attraction for less favorable areas.
