description: Η παρούσα εργασία εξετάζει τη στρατηγική αξιοποίηση των μεταναστευτικών ροών στο πλαίσιο των μέσων μαζικής ενημέρωσης πολιτικοποιημένων εφημερίδων και περιοδικών στην Ελλάδα. Παράλληλα, μελετάται σχετική έρευνα για την αποτελεσματική διαχείριση της μαζικής μετανάστευσης προς την ΕΕ. Στην διπλωματική αυτή εργασία, θα παρατεθούν τα σημαντικότερα γεγονότα που πλαισίωσαν την περίοδο του Φεβρουαρίου 2020, αναφορικά με τις προσφυγικές ροές στην περιόχη των συνόρων του Εβρου και στην συνεχεία θα εξεταστούν οι τρόποι που τα ελληνικά ΜΜΕ παρουσίασαν την κρίση αυτή. Θα προσπαθήσουμε να αποτυπώσουμε τον τρόπο με τον οποίο κάποια ελληνικά ειδησεογραφικά ΜΜΕ παρουσίασαν τα γεγονότα που σχετίστηκαν με τα δρώμενα των ημερών αυτών. Θα επιλεχτούν συγκεκριμένοι ειδησεογραφικοί ιστότοποι (sites) που να είναι φίλα προσκείμενοι στην ελληνική κυβέρνηση, όσο και sites που εκφράζουν την αντιπολίτευση, ώστε να υπάρχει τόσο αντικειμενικό δείγμα άρθρων/δημοσιευμάτων, όσο και σφαιρική επισκόπηση του αντικειμένου που εξετάζεται. Για την ανεύρεση των προς εξέταση δημοσιευμάτων θα χρησιμοποιηθούν συγκεκριμένες λέξεις κλειδιά, στην εσωτερική μηχανή αναζήτησης που διαθέτουν οι συγκεκριμένοι ιστότοποι. Εν συνεχεία θα εξεταστούν και θα συγκριθούν τα δημοσιεύματα αυτά ως προς τον τρόπο παρουσίασης των γεγονότων και τα τεχνικά χαρακτηριστικά που χρησιμοποίησαν στην γραφή τους οι αρθρογράφοι με απώτερο σκοπό να επηρεάσουν ή μη την κοινή γνώμη προς συγκεκριμένη κατεύθυνση.
description: This paper examines the strategic exploitation of migration flows in the context of the mass media of politicized newspapers and magazines in Greece. At the same time, relevant research is being studied for the effective management of mass migration to the EU. In this diplomatic work, the most important events that framed the period of February 2020, regarding the refugee flows in the area of the Evros border, will be listed and then they will be examined the ways in which the Greek mass media presented this crisis. We will try to capture the way in which some Greek news media presented the events related to the events of those days. Specific news websites that are close to the Greek government will be selected, as well as sites that express the opposition, so that there is both an objective sample of articles/publications and a global overview of the subject under consideration. In order to find the publications to be examined, specific keywords will be used in the internal search engine of the specific websites. Subsequently, these publications will be examined and compared in terms of the way of presenting the facts and the technical characteristics used in their writing by the columnists with the ultimate aim of influencing or not public opinion in a specific direction.

description: The study analyses the strategies Ita-lian farmers use to cope with the risks that face their production. We develop cross-sectional and longi-tudinal analyses as well as analyses of correlation that underline the main differences between the way farms adapt their structure and management towards risk. The expected output is an analysis of farms’ approach to risk management in relation to the risk exposure. The present study is the result of research conducted by INEA “Research and techni-cal support on natural disasters, climatic and phyto-sanitary risks in agriculture and related policies”, funded by the Italian Ministry of Agricultural Food and Forestry Policies. The main aim of this analysis is to explore the potential and the limitations of economic tools for climatic risk management in agriculture of new CAP 2013-2020 in relation to farms’ needs, possible or necessary policies and future directions in the context of the Italian experience (National Solidarity Fund for natural disasters in agriculture, legislative decree n. 102/2004). The chosen approach for the analysis of demand consi-ders the climatic risk at the level of farms’ approach to hedging risks in terms of the use of technical tools (agricultural practices, pesticides, fertilizers, irriga-tion) and economic/financial instruments (insuran-ces, etc.). The results show a preference of technical tools and a strong need of a more integrated policy scheme, arising also from a new system and the potential synergies between risk management tools and other rural development measures of a more structural and management nature. The latter can contribute to a reduction of risk exposure and of the farms’ vulnerability, first and foremost through agro-climatic-environmental measures, production diversification, irrigation infrastructures, technolo-gical and management innovations and formation-information-consultancy.
Net Energy Metrics Reveal Striking Disparities Across United States Households

Year: 2021

description: Energy poverty in the United States is an issue of increasing urgency, exacerbated by rising inequality. Few policy-relevant datasets evaluate the energy burden of typical American households. Here, we develop a framework using net energy analysis and socioeconomic data at the census tract-level to observe systematic energy inequity across the United States among critical groups that heed policy attention. We find substantial instances of energy poverty in the United States -- 10% of households experience energy poverty as presently defined as spending more than 10% of household income on energy expenditures. While 78% of households below the federal poverty line also face energy poverty, fewer than 0.29% of those above the federal poverty line face this scarcity. The federal poverty line is not enough to capture the experience and disparity in energy poverty across the United States and excludes households that would benefit immensely from programs available to support low-income communities. We identify that energy expenditures across census tracts disproportionately burden Black, Hispanic, and Native American communities. For solar, wind, and energy efficiency to address socioeconomic mobility, programs must reduce relative energy expenditures by expanding eligibility requirements for support and access to improved conservation measures, efficiency upgrades, and distributed renewables. We recommend the United States develop a more inclusive federal energy poverty categorization that provides greater assistance for household energy costs.

description: The model is presented of H$_2$O maser in the $1_{10}-1_{01}$ line within the first excited vibrational state of the molecule around oxygen-rich asymptotic giant branch stars. It is suggested that the maser cloud is located in the inner layers of the circumstellar envelope where intense dust formation takes place. The calculations took into account rotational levels belonging to the five lowest vibrational states of the H$_2$O molecule. The model predicts the gain values of the 658-GHz maser about $10^{-14} -10^{-13}$ cm$^{-1}$ at H$_2$ molecule concentrations $10^9 - 10^{11}$ cm$^{-3}$ and at high ortho-H$_2$O concentrations $ \gtrsim 10^5$ cm$^{-3}$. The gas temperatures $1000 - 1500$ K are considered to be a necessary condition for the effective maser operation. Results are presented for other maser transitions of the excited vibrational states of the molecule.

description: Vortex flows, related to solar convective turbulent dynamics at granular scales and their interplay with magnetic fields within intergranular lanes, occur abundantly on the solar surface and in the atmosphere above. Their presence is revealed in high-resolution and high-cadence solar observations from the ground and from space and with state-of-the-art magnetoconvection simulations. Vortical flows exhibit complex characteristics and dynamics, excite a wide range of different waves, and couple different layers of the solar atmosphere, which facilitates the channeling and transfer of mass, momentum and energy from the solar surface up to the low corona. Here we provide a comprehensive review of documented research and new developments in theory, observations, and modelling of vortices over the past couple of decades after their observational discovery, including recent observations in Hα, innovative detection techniques, diverse hydrostatic modelling of waves and forefront magnetohydrodynamic simulations incorporating effects of a non-ideal plasma. It is the first systematic overview of solar vortex flows at granular scales, a field with a plethora of names for phenomena that exhibit similarities and differences and often interconnect and rely on the same physics. With the advent of the 4-m Daniel K. Inouye Solar Telescope and the forthcoming European Solar Telescope, the ongoing Solar Orbiter mission, and the development of cutting-edge simulations, this review timely addresses the state-of-the-art on vortex flows and outlines both theoretical and observational future research directions.

description: Trimethylchlorosilane silylated silica aerogel (TS-SA) was loaded with a model drug, aspirin. TS-SA preparation, drug loading, and drying were performed through ambient pressure techniques in a safe and cheap manner. The sample structure, drug loading, and drug dissolution profiles were characterized by N2 adsorption and desorption analysis, FT-IR spectroscopy, UV absorption spectroscopy, FE-EM, EDX, XRD, and DSC. The characterization results indicated drug molecules are successfully loaded on the entire nanostructure of TS-SA. Specific surface area, total pore volume, and average pore size decrease with drug loading in TS-SA structure, as well as XRD and DSC results are indicating the amorphous state of loaded aspirin. Drug adsorption isotherm was measured and fitted well by the Freundlich model. Drug release kinetics from the samples were also evaluated in 0.1 N HCl (pH 1.2) and phosphate buffer (pH 7.4). The zero-order model, the first-order model, and the Higuchi model were employed to study the release kinetics. Better fitting to the Higuchi model showed that Fick's diffusion governs the aspirin release mechanism. The release rate of loaded samples was slower than the pure drug in both HCl and phosphate buffer. As pure aspirin dissolves totally in 0.1 N HCl and phosphate buffer within 40 min and 20 min, respectively, loaded drug dissolve 35% ± 4 and 80% ± 4 in 0.1 N HCl and phosphate buffer within 100 min. The ambient pressure drug loading on TS-SA could have interesting potential applications in controlled release drug delivery systems.
Generalized nuclear contacts and the nucleon's momentum distributions

description: The general nuclear contact matrices are defined, taking into consideration all partial waves and finite-range interactions, extending Tan's work for the zero range model. The properties of these matrices are discussed and the relations between the contacts and the one-nucleon and two-nucleon momentum distributions are derived. Using these relations, a new asymptotic connection between the one-nucleon and two-nucleon momentum distributions, describing the two-body short-range correlations in nuclei, is obtained. Using available numerical data, we extract few connections between the different contacts and verify their relations to the momentum distributions. The numerical data also allows us to identify the main nucleon momentum range affected by two-body short-range correlations. Utilizing these relations and the numerical data, we also verify a previous independent prediction connecting between the Levinger constant and the contacts. This work provides an important indication for the relevance of the contact formalism to nuclear systems, and should open the path for revealing more useful relations between the contacts and interesting quantities of nuclei and nuclear matter.

description: This is an introduction to models of accretion discs around black holes. After a presentation of the non-relativistic equations describing the structure and evolution of geometrically thin accretion discs we discuss their steady-state solutions and compare them to observation. Next we describe in detail the thermal-viscous disc instability model and its application to dwarf novae for which it was designed and its X-ray irradiated-disc version which explains the soft X--ray transients, i.e. outbursting black-hole low-mass X-ray binaries. We then turn to the role of advection in accretion flows onto black holes illustrating its action and importance with a toy model describing both ADAFs and slim discs. We conclude with a presentation of the general-relativistic formalism describing accretion discs in the Kerr space-time.

description: Time is a valuable resource and it seems intuitive that longer time should lead to better precision in Hamiltonian parameter estimation. However recent studies have put this intuition into question, showing longer time may even lead to worse estimation in certain cases. Here we show that the intuition can be restored if coherent feedback controls are included. By deriving asymptotically optimal feedback controls we present a quantification of the maximal improvement feedback controls can provide in Hamiltonian parameter estimation and show a universal time scaling for the precision limit of Hamiltonian parameter estimation under the optimal feedback scheme.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Objective: To evaluate and compare the amount of volumetric wear of bulk-fill composite resin to conventional composite resin and human enamel after thermo-mechanical loading. Materials and Methods: Five composite resins (n=10) were tested: four bulk-fill composite resins (Filtek One Bulk Fill [3M Oral Care], Tetric EvoCeram Bulk Fill [Ivoclar Vivadent], Tetric PowerFill [Ivoclar Vivadent], SonicFill 3 [Kerr Corp.]) and one conventional composite (Filtek Supreme Ultra [3M Oral Care]). Enamel from recently extracted teeth was used as control. Specimens were subjected to a 2-body volumetric wear evaluation using a chewing simulator (CS-4.8, Mechatronik). Disc-shaped specimens (3 mm×10 mm) received 500,000 load cycles against steatite antagonists while simultaneously thermocycled (5,000 cycles, 5-55°C). Volumetric wear (mm3) was measured using the Geomagic Control X software (3D Systems) based on before and after Trios 3 (3Shape) digital scanner images of the specimens. Scanning electron microscope analysis of wear facets and composite resin fillers’ shape and size was performed. Volumetric wear was statistically analyzed using the one-way ANOVA and Tukey’s post-hoc test (α=0.05). Results: All tested composite resins wore at rates significantly higher than enamel (P<0.05). The mean volumetric wear of the composite resins ranged from 1.01 mm3 to 1.48 mm3, while enamel had a mean volumetric wear of 0.25 mm3. Bulk-fill composite resins showed higher wear resistance than the conventional composite resin. Conclusions: Under the study parameters, enamel was more resistant to wear then all composite resins tested. Bulk-fill composite resins presented higher wear resistance than the conventional composite resin.
ADVANCED IMMUNOSENSING PLATFORMS FOR BIOMONITORING AND ENVIRONMENTAL MONITORING

Publisher: name: Washington State University

Subjects: Materials Science

description: Chemical analysis of complex sample matrix is significant towards the efficient monitoring of human and environmental health. In the area of environmental contamination control and disease diagnosis, traditional analytical approaches rely on the separation effects by chromatography, such as gas chromatography (GC) and liquid chromatography (LC). Although GC/LC coupled with various detectors are extensively employed in analytical settings as the mature technologies, the disadvantages are also obvious, including the dependence on large and bulky instruments, complex and time-consuming instrumental operation, inevitable sample pretreatment and high cost. These disadvantages greatly limit their application in rapid diagnosis of disease, on-site samples testing, and household preclinic diagnosis. Immunosensing approaches, however, are promising substitutes applicable to the above scenarios. Featured with extraordinary selectivity and accuracy of detection attributed to the specific antibody-antigen recognition, immunoassays (IAs) have attracted extensive interests in recent years. Nevertheless, the major challenges are to overcome the inherent defects of IAs, such as low sensitivity of detection and difficult to realize multi-target simultaneous detection, in the meantime, to develop high-performance portable detection platforms. In this dissertation, advanced immunosensing platforms based on the principle of enzyme-linked immunosorbent assay (ELISA) and lateral flow immunoassay (LFIA) were systematically explored from the aspects of biorecognition, signal amplification, and signal quantification. Advanced functional nanomaterials, including metal-organic framework (MOF), graphene, carbon dot, mesoporous nanocomposite, etc., with unique physical or chemical properties were synthesized and employed as signal reporters in IAs for amplified sensitivity of detection. In addition, we designed and manufactured immunosensing platforms using 3D printing to achieve optimal integration of immunoassays, nanomaterials, and quantitative detection methods, thus the on-site, point-of-care, high-performance sample assessment was realized. Further, the extraordinary analytical performances of the immunosensing platforms were validated in practical applications for the detection of woodsmoke biomarkers in various human biofluids representing the exposure of human to contaminated air from wildfires, as well as the detection of environmental pesticide contaminants and the corresponding human metabolites in biofluids.

Year: 2019

description: This thesis aims to explore the development of voice in the workplace and how employee voice has been used in the case study organisation as it moves towards closedown and to determine what mechanisms have been put in place to enable employee voice in CarCo. Measures of employee voice will be used as indicators of management attitudes towards employee participation (Bryson,1999; Benson & Brown, 2010; Pyman, Holland, Teicher and Cooper, 2010). This thesis will also then compare results at two points in time to trace any changes in the type or extent of employee voice as well as employer attitudes during this period. The study will use an in-depth case study method to analyse the use of employee voice in the gradual closedown of manufacturing at CarCo.
Young farmer and farm performance

Subjects: Farm Management

description: Recent data on the Italian farms con-firm the excessive aging of farmers. Most of the literature argues that a low inclusion of young people in the management of the farms determines a reduction in strength and farm efficiency, consequently increasing the risk of disinvestment of farming. The resolution of this problem becomes, therefore, an imperative for the Common agricultural policy (CAP), wanting to prevent the abandonment of domestic agriculture. So, much of the literature has devoted to this topic, but it has rarely provided statistical evidences on the relationship between age of farmer and farm performance. With the aim to added empirical evidences on this issue I use different econometric techniques on a panel data of the Farms Accounting Data Network (FADN), trying, primarily, to investigate in detail this relationship, showing the changes in the different productive contest and for dissimilar dimension of farm performance; secondly, to verify the presence of a probable reverse causality in this correlation, which is determined by the top per-forming farms that encourage young entrepreneurs to get into the agricultural business. The main results showed that: there is a positive correlation between young farmers and farms performance that remain positive even if I focused in specific agricultural sec-tors and using different proxy for farm performance; but when I control for the endogeneity of the age variable the relationship young-performance change the sign, showing that the observed “performing effect” of young farmer is due mainly to the ability of the elderly farmer, aiming pass or sell their farm, rather than the skill of the young farmer incoming.

description: Decoupling is an important tool to prolong the coherence time of quantum systems. Most decoupling schemes have been assuming selective controls on the system and it is believed that with global pulses one can only decouple systems with certain coupling terms like secular dipole-dipole coupling. In this article we show that with global pulses it is possible to reduce the coupling strength of other types of coupling, which we demonstrate with Ising coupling. The complexity of such pulses is independent of the size of system.

description: We demonstrate the existence of a set of novel discrete symmetry transformations in the case of an interacting N = 2 supersymmetric quantum mechanical model of a system of an electron moving on a sphere in the background of a magnetic monopole and establish its interpretation in the language of differential geometry. These discrete symmetries are, over and above, the usual three continuous symmetries of the theory which together provide the physical realizations of the de Rham cohomological operators of differential geometry. We derive the nilpotent N = 2 SUSY transformations by exploiting our idea of supervariable approach and provide geometrical meaning to these transformations in the language of Grassmannian translational generators on a (1, 2)-dimensional supermanifold on which our N = 2 SUSY quantum mechanical model is generalized. We express the conserved supercharges and the invariance of the Lagrangian in terms of the supervariables (obtained after the imposition of the SUSY invariant restrictions) and provide the geometrical meaning to (i) the nilpotency property of the N = 2 supercharges, and (ii) the SUSY invariance of the Lagrangian of our N = 2 SUSY theory.

description: In this paper, we explore the effects of dialectal diversity on economic performance by drawing evidence from Chinese prefecture-level cities. Our dataset is a panel of 5-year average data over the period from 2001 to 2015 including 274 cities. We compute five indices of Chinese dialectal diversity: 1. Dialectal fractionalization; 2. Adjusted dialectal fractionalization; 3. Dialectal polarization; 4. Adjusted dialectal polarization and 5. Periphery heterogeneity. We find that dialectal fractionalization and dialectal polarization as well as periphery heterogeneity have a positive effect on both income per capita and economic growth. Adjusted dialectal fractionalization exhibits a positive effect only on the change in economic growth over time. However, adjusted dialectal polarization does not show any robust effects. Furthermore, the experience of being governed by the Chinese Communist Party during the revolutionary war inhibits the negative effects of dialectal diversity in eastern China, while it has persistent negative effects in central and north-eastern regions of the country.

description: In this conference contribution, the main focus should be on the emergence or gradual discovery of this circular constant. From where it arose with high probability? Is our present-day π really the ancient used constant or coefficient itself? Why did π or the underlying ratio gain scientific importance? When and how was π calculated more precisely in ancient times?

description: We experimentally study the effects of the anisotropic Rydberg-interaction on $D$-state Rydberg polaritons slowly propagating through a cold atomic sample. In addition to the few-photon nonlinearity known from similar experiments with Rydberg $S$-states, we observe the interaction-induced dephasing of Rydberg polaritons at very low photon input rates into the medium. We develop a model combining the propagation of the two-photon wavefunction through our system with nonperturbative calculations of the anisotropic Rydberg-interaction to show that the observed effect can be attributed to pairwise interaction of individual Rydberg polaritons.

description: The sediments of lakes and reservoirs produce significant amounts of the powerful greenhouse gas methane (CH4). Characterizing the rate, timing, and controls on the transport of CH4 from sediments is critical for understanding emissions from lacustrine ecosystems. In this dissertation, we explore environmental and anthropogenic drivers of CH4 flux from lake sediments at multiple spatiotemporal scales and address several methodological challenges to measuring CH4 transport into lake water columns.In the first chapter, we examine rates of sediment CH4 production and consumption (oxidation) in a global dataset of lakes and reservoirs. Sediment CH4 production rates positively correlated with lake biological productivity, and systems with greater sediment CH4 production rates had less efficient oxidation. Together, our findings indicate eutrophication may increase emissions from lake and reservoir surfaces by driving greater transport of CH4 from sediments into the water column.
description: The second chapter presents a novel approach for measuring flux a short distance above sediments. The flux gradient method provides a non-invasive, in situ measurement of flux at an hourly temporal resolution. We apply this method in a eutrophic reservoir and suggest that significant changes in CH4 fluxes observed within hours may be linked to fluctuations in CH4 oxidation and/or near-bed turbulence. Although CH4 fluxes increased from spring to summer, we report that most CH4 was oxidized in the hypolimnion. Our results are the first to examine CH4 flux variability and controls on hourly and seasonal time scales. In addition, the developed method is a promising future tool for quantifying other solute fluxes.
description: Finally, the third chapter is a critical review of common approaches available for measuring CH4 flux from lake sediments. We highlight important caveats to consider when comparing fluxes across studies, such as some methods disturbing microbial activity, excluding sediment surface processes, or ignoring CH4 dynamics in deeper sediment. We argue that the coarse spatiotemporal resolution and ex situ nature of most techniques have resulted in a poor understanding of the sub-daily variability and controls on CH4 transport from sediments. Lastly, we identify future methodological advancements needed, such as eddy correlation techniques, modeling approaches, and explicit method comparison studies.

description: We consider a class of invariant measures for a passive scalar $f$ driven by an incompressible velocity field $\boldsymbol{u}$, on a $d$-dimensional periodic domain, satisfying $$ \partial_t f + \boldsymbol{u} \cdot \nabla f = 0, \qquad f(0)=f_0. $$ The measures are obtained as limits of stochastic viscous perturbations. We prove that the span of the $H^1$ eigenfunctions of the operator $\boldsymbol{u}\cdot\nabla$ contains the support of these measures. We also analyze several explicit examples: when $\boldsymbol{u}$ is a shear flow or a relaxation enhancing flow (a generalization of weakly mixing), we can characterize the limiting measure uniquely and compute its covariance structure. We also consider the case of two-dimensional cellular flows, for which further regularity properties of the functions in the support of the measure can be deduced. The main results are proved with the use of spectral theory results, in particular the RAGE theorem, which are used to characterize large classes of orbits of the inviscid problem that are growing in $H^1$.

Navajo Desire in the Settler-Colonial Present: overgrazing, grazing regimes, and development

description: Since 1868, Navajo self-determination has been marginalized by the unequal power relations between Navajo people and the U.S. government. Colonial relations manifests historically as an imposition of a forced livestock reduction, a grazing regime, and the uneven-development in the Navajo Nation. A history of an imposed grazing regime and uneven-development converge in the present to shape Navajo desires for development. Development in Indigenous nations is characterized as problematic for its function in extending and proliferating exploitive colonial relations. Thinking about the history of uneven-development and a grazing regime in terms of Navajo desire offers a vital lens to understanding how Indigenous people continue and navigate a settler-colonial present. Utilizing archived speeches, letters, and meeting minutes with ethnographic research, I explore how histories converge in the present to shape Navajo desires. Engaging with Marxist geography, Indigenous geography, and affective theory I examine contemporary Navajo desires for development are shaped in settler-colonialism.

Διεθνείς οργανισμοί, Μ.Κ.Ο. και δημόσια υγεία: το μείγμα χρηματοδότησης, η κατανομή πόρων και η αποδοτικότητα των δράσεών τους

description: Με την υγεία να συνιστά ένα επαπειλούμενο αγαθό, μέσα σε ένα άκρως παγκοσμιοποιημένο περιβάλλον, και τις περιβαλλοντικές συνθήκες συνεχώς μεταβαλλόμενες, η μελέτη των πολιτικών και των οικονομικών της υγείας αναδεικνύονται στον ακρογωνιαίο λίθο για την εφαρμογή όσων οι αμιγώς υγειονομικές επιστήμες ανακαλύπτουν και ερευνούν. Η παγκόσμια υγεία, υπό το πρίσμα της «μίας υγείας» δεν είναι υπόθεση μόνο των ισχυρών κρατών. Οι επιδημικές και πανδημικές κρίσεις δεν περιορίζονται σε σύνορα, υπενθυμίζοντάς μας πως η επίτευξη της καθολικής κάλυψης στην υγεία είναι μία διαδικασία δαπανηρή, και η σωστή εφαρμογή της προϋποθέτει μηχανισμούς ελέγχου και αξιολόγησης, αφενός για να αποφεύγονται ζητήματα κακοδιαχείρισης, αφετέρου για να μπορούμε να προσεγγίζουμε αποδοτικά, υπό όρους κόστους και αποτελεσματικότητας, τις παρεμβάσεις για την επίτευξή της. Η Αναπτυξιακή Βοήθεια για την Υγεία, ειδικά για την περιοχή αναφοράς της παρούσας μελέτης (Υποσαχάρια Αφρική), λόγω των πολύ χαμηλών κρατικών προϋπολογισμών υγείας και αναλόγως κρατικών δαπανών, λαμβάνει χαρακτήρα υποκατάστασης του κρατικού μηχανισμού. Ειδικά για τις μεταδιδόμενες ασθένειες και τις νόσους αναφοράς (HIV, Φυματίωση και Μαλάρια) κρίνεται αναγκαία, και μάλιστα, ακόμα και στις περιπτώσεις μη καλής απόδοσης, αφενός διότι δίχως αύξηση των κρατικών δαπανών δεν υπάρχουν εναλλακτικές, αφετέρου διότι οποιαδήποτε μείωση ή τερματισμός τους θα είχε καταστροφικά αποτελέσματα. Για την εξαγωγή αποτελεσμάτων και συμπερασμάτων χρησιμοποιείται για πρώτη φορά μία τρισδιάστατη καινοτόμα προσέγγιση ως προς την ομαδοποίηση - οπτική των δεδομένων (χώρες, ομάδες χωρών, νοσήματα) και αντίστοιχη τριπλή προσέγγιση ανάλυσης (στατιστική ανάλυση, χαρτογράφηση και ανάλυση κόστους-αποτελεσματικότητας). Ανάλογη είναι και η εικόνα των μηχανισμών οικονομικής ενίσχυσης των φορέων της κοινωνίας των πολιτών, που επιχειρούν στο χώρο της υγείας, από την ιδιωτική πρωτοβουλία, η οποία αντλείται από την παρούσα μελέτη, και η οποία αποτελεί την πρώτη για την περίπτωση της Ελλάδας. Για την αποφυγή μη αποδοτικών πρακτικών, εμπορευματοποίησης είναι αναγκαία η αξιολόγηση και η θέσπιση νέων μέτρων διαφάνειας ως προς τις συναλλαγές μεταξύ των συμβαλλομένων.

description: We use a tunable laser ARPES to study the electronic properties of the prototypical multiband BCS superconductor MgB2. Our data reveal a strong renormalization of the dispersion (kink) at ~65 meV, which is caused by coupling of electrons to the E2g phonon mode. In contrast to cuprates, the 65 meV kink in MgB2 does not change significantly across Tc. More interestingly, we observe strong coupling to a second, lower energy collective mode at binding energy of 10 meV. This excitation vanishes above Tc and is likely a signature of the elusive Leggett mode.

COVID-19

description: Das Poster zeigt die Anwendung von LinkedOpenData in der GIS Community mit QGIS am aktuellen Anwendungsbeispiel COVID-19 und ist in zwei Teile aufgeteilt. Der erste Teil skizziert, wie man mit Konvertierungstools Geodaten nach RDF überführen und zu Geokonzepten interlinken kann - den sogenannten Semantic Upflit. Diese Geodaten können anschließend als Linked Data in einem Triple Store zur Verfügung gestellt werden. Im Kontext der COVID-19 Pandemie sind hier insbesondere Ländergrenzen, sowie innerdeutsche Grenzen wie Bundesländer und Landkreise von Bedeutung. Diese Geodaten wurden mit Hilfe der Schnittstellen der Johns Hopkins University und des Robert Koch-Instituts mit COVID-19 Daten angereichert. Die integrierten Daten können jedoch noch mit weiteren Linked Data Datenquellen angereichert werden. Hierfür zeigen wir ein Beispiel. Hier bietet sich z.B. Wikidata an, wofür wir Beispiele (Einwohnerzahl, etc.) zeigen. Der zweite teil zeigt zwei Methoden wie diese Geodaten in der Geocommunity verarbeitet werden können. Der erste Weg ist das SPARQLing Unicorn QGIS Plugin welches es ermöglicht ein SPARQL Query direkt an einen Triple Store abzuschicken und die Ergebnisse als Layer in QGIS zu verarbeiten. Das SPARQLing Unicorn QGIS Plugin kann hierbei jedoch auch als Vorbereitung für eine zweite Methode dienen: den SemanticWFS. Der SemanticWFS ist ein Web Feature Service, welcher Triple Stores als Backends zulässt. Benutzer können mit dem SPARQLing Unicorn QGIS Plugin ein Query an den Triple Store testen und im SemanticWFS das Query als FeatureType konfigurieren. Anschließend kann das Ergebnis des SPARQL Queries in einem der vom SemanticWFS angebotenen Formate zurückgegeben und zum Beispiel in QGIS als WFS eingebunden werden. Dieser Weg ist für Benutzer gedacht, welche über keine Kenntnisse in der SPARQL Query Sprache verfügen und bietet die Möglichkeit über Linked Data angereicherte Daten zielgerichtet als Geowebservice zur Verfügung zu stellen. Wir stellen somit zwei neue Wege vor, Linked Data in einem GIS zu nutzen und motivieren die Integration und Nutzung von Linked Data an einem konkreten Beispiel.
