description: Κυρίαρχη έννοια της διατριβής αποτελούν οι πολυεθνικές εταιρίες σε σχέση με τα ανθρώπινα δικαιώματα. Εξετάζεται κατά πόσο οι πολυεθνικές εταιρίες μπορούν να παραβιάσουν τα ανθρώπινα δικαιώματα και γενικότερα το διεθνές δίκαιο. Ερευνάται λοιπόν το ζήτημα της διεθνούς νομικής προσωπικότητας των πολυεθνικών εταιριών και της αναγνώρισης τους ως υποκείμενα του διεθνούς δικαίου. Γίνεται αναφορά στον διαχωρισμό ανάμεσα στα κράτη και τους μη κρατικούς-δρώντες και την επίδραση των τελευταίων στο διεθνές πεδίο. Ακόμη εξετάζεται η ευθύνη των πολυεθνικών εταιριών για παραβιάσεις ανθρωπίνων δικαιωμάτων δίνοντας έμφαση στο δικαιικό σύστημα των Ηνωμένων Πολιτειών της Αμερικής και στη συνέχεια στο σύστημα της Ευρωπαϊκής Ένωσης. Συγκεκριμένα αναλύεται ο νόμος της Alien Tort Claims Act στις Ηνωμένες Πολιτείες της Αμερικής και η σχετική νομολογία των δικαστηρίων της χώρας. Ακολούθως, αναλύονται οι διατάξεις του κανονισμού των Βρυξελλών και του κανονισμού Ρώμη ΙΙ στο σύστημα της Ευρωπαϊκής Ένωσης που σχετίζονται με το θέμα της εργασίας, καθώς και η υπάρχουσα νομολογία. Τέλος εξετάζεται το ζήτημα από την σκοπιά του συγκριτικού δικαίου και γίνονται ορισμένες παρατηρήσεις και συγκρίσεις ανάμεσα στα δύο δικαιικά συστήματα.
description: The basic concept of the present thesis is the role of multinational corporations in violations of human rights. It examines whether multinational corporations are capable of violating human rights and more generally violating international law. Accordingly, it analyses the issue of international personality of multinational corporations as being subjects of international law. There is a reference on the distinction between states and non-state actors and the impact it has on international level. Then the issue of liability of multinational corporations is examined especially in the United States of America and in the European Union. There is an analysis of the Alien Tort Claims Act and the relative jurisprudence in the United States. Furthermore, the rule of the Brussels Regulation and Rome II in the European Union is examined, as well as the case law that relates to violations of human rights by European multinational corporations. In the end there is a comparative study of the phenomenon between the two jurisdictions.

description: The starting point of securing a network is having a concise overview of it. As networks are becoming more and more complex both in general and with the introduction of IoT technology and their topological peculiarities in particular, this is increasingly difficult to achieve. Especially in cyber-physical environments, such as smart factories, gaining a reliable picture of the network can be, due to intertwining of a vast amount of devices and different protocols, a tedious task. Nevertheless, this work is necessary to conduct security audits, compare documentation with actual conditions or found vulnerabilities using an attacker's view, for all of which a reliable topology overview is pivotal. For security auditors, however, there might not much information, such as asset management access, be available beforehand, which is why this paper assumes network to audit as a complete black box. The goal is therefore to set security auditors in a condition of, without having any a priori knowledge at all, automatically gaining a topology oversight. This paper describes, in the context of a bigger system that uses active scanning to determine the network topology, an approach to automate the first steps of this procedure: passively scanning the network and determining the network's scope, as well as gaining a valid address to perform the active scanning. This allows for bootstrapping an automatic network discovery process without prior knowledge.

description: We try to review the main current ideas and points of view on the running coupling constant in QCD. We begin by recalling briefly the classic analysis based on the Renormalization Group with some emphasis on the exact solutions of the RG equation for a given number of loops, in comparison with the usual approximate expressions. We give particular attention to the problem of eliminating the unphysical Landau singularities, and of defining a coupling that remains significant at the infrared scales. We consider various proposals of couplings directly related to the quark-antiquark potential or to other physical quantities (effective charges) and discuss optimization in the choice of the scale parameter and of the RS. Our main focus is, however, on dispersive methods, their application, their relation with non-perturbative effects. We try also to summarize the main results obtained by Lattice simulations in various MOM schemes. We conclude briefly recalling the traditional comparison with the experimental data.

description: The co-evolution between supermassive black holes and their environment is most directly traced by the hot atmospheres of dark matter halos. Cooling of the hot atmosphere supplies the central regions with fresh gas, igniting active galactic nuclei (AGN) with long duty cycles. Outflows from the central engine tightly couple with the surrounding gaseous medium and provide the dominant heating source preventing runaway cooling by carving cavities and driving shocks across the medium. The AGN feedback loop is a key feature of all modern galaxy evolution models. Here we review our knowledge of the AGN feedback process in the specific context of galaxy groups. Galaxy groups are uniquely suited to constrain the mechanisms governing the cooling-heating balance. Unlike in more massive halos, the energy supplied by the central AGN to the hot intragroup medium can exceed the gravitational binding energy of halo gas particles. We report on the state-of-the-art in observations of the feedback phenomenon and in theoretical models of the heating-cooling balance in galaxy groups. We also describe how our knowledge of the AGN feedback process impacts on galaxy evolution models and on large-scale baryon distributions. Finally, we discuss how new instrumentation will answer key open questions on the topic.

description: Growing evidence indicates that the synchrotron radiation mechanism may be responsible for the prompt emission of gamma-ray bursts (GRBs). In the synchrotron radiation scenario, the electron energy spectrum of the prompt emission is diverse in theoretical works and has not been estimated from observations in a general way (i.e., without specifying a certain physical model for the electron spectrum). In this paper, we creatively propose a method to directly estimate the electron spectrum for the prompt emission, without specifying a certain physical model for the electron spectrum in the synchrotron radiation scenario. In this method, an empirical function (i.e., a four-order Bezier curve jointed with a linear function at high-energy) is applied to describe the electron spectrum in log-log coordinate. It is found that our empirical function can well mimic the electron spectra obtained in many numerical calculations or simulations. Then, our method can figure out the electron spectrum for the prompt emission without specifying a model. By employing our method on observations, taking GRB 180720B and GRB 160509A as examples, it is found that the obtained electron spectra are generally different from that in the standard fast-cooling scenario and even a broken power law. Moreover, the morphology of electron spectra in its low-energy regime varies with time in a burst and even in a pulse. Our proposed method provides a valuable way to confront the synchrotron radiation mechanism with observations.

description: Solving a singular linear system for an individual vector solution is an ill-posed problem with a condition number infinity. From an alternative perspective, however, the general solution of a singular system is of a bounded sensitivity as a unique element in an affine Grassmannian. If a singular linear system is given through empirical data that are sufficiently accurate with a tight error bound, a properly formulated general numerical solution uniquely exists in the same affine Grassmannian, enjoys Lipschitz continuity and approximates the underlying exact solution with an accuracy in the same order as the data. Furthermore, any backward accurate numerical solution vector is an accurate approximation to one of the solutions of the underlying singular system.
Unlinking summer new particle formation and high ozone episodes

description: New particle formation (NPF) and ozone (O3) episodes are products of photochemically-driven processes. However, O3 formation occurs under the presence of precursors (Monks et al., 2015), whereas NPF usually requires clean atmospheres (Boy and Kulmala, 2002). Clustering studies on particle number size distribution (PNSD) time series in high insolation urban areas revealed the frequent occurrence of photochemical NPF in spring and summer (Brines et al., 2015). Averaged O3 concentrations reached the highest concentrations for the NPF-cluster in most of the studied cities. We intend here to elucidate if this simultaneous peaking of NPF and O3 is due to the similar seasonal patterns of both pollutants or because NPF episodes coincide with high O3 episodes. To this end we analyzed 2014-2018 spring and summer time series of PNSD and O3 concentrations at Montseny, a regional background station 40 km NE of Barcelona (Spain) included in the ACTRIS and GAW networks.We categorized NPF events with the method proposed by (Dal Maso et al., 2005). K-means clustering was applied to the O3 daily series. The number of clusters was chosen so that only one clusters contained all the days registering an exceedance of the information value (180 μg m-3 h-1), using the minimum number of clusters. This was achieved by using 4 clusters. For each of them we studied the occurrence of NPF and the average daily cycles of other variables: PNSD, concentration of NO2, SO2, and PM1, and meteorological variables. The results suggest that, for spring and summer, the highest regional background UFPs concentrations coincide with the highest O3 episodes, but the probability of NPF during these days is the lowest, even though the nucleation-mode number concentration is the highest. These days also present the maximum temperature, solar radiation, and wind speed, and the lowest relative humidity. The condensation sink and concentration of other pollutants are also the highest and peak simultaneously with the wind speed. This suggests that during these days pollutants are transported from the Barcelona metropolitan area to the regional background station. Conversely, when the plume does not reach the station, UFPs and O3 concentrations are the lowest, and the probability of NPF is the highest.

description: An inverse boundary value problem for the Helmholtz equation in a bounded domain is considered. The problem is to extract information about an unknown obstacle embedded in the domain with unknown impedance boundary condition (the Robin condition) from the associated Dirichlet-to-Neumann map. The main result is a characterization of the unknown obstacle via the sequences that are constructed by the Dirichlet-to-Neumann map, under smallness conditions on the wave number and the upper bound of the impedance. Moreover two alternative simple proofs of a previous result of Cheng-Liu-Nakamura which are based on only some energy estimates, an analysis of the blowup of the energy of so-called reflected solutions and an application of the enclosure method to the problem are also given.

It permits to explain the mass splitting of leptons (e,mu,tau). Recently, the interest has grown to this model (see, for instance, the papers by S. Kruglov and J. P. Vigier et al). We continue the research deriving the equation from the first principles, finding dynamical invariants for this model, investigating the influence of potential interactions.

Whether Neel AF ordering in 2D can be dominantly induced by electron-phonon couplings (EPC) has not been completely understood. Here, by employing numerically-exact sign-problem-free quantum Monte Carlo (QMC) simulations, we show that optical Su-Schrieffer-Heeger (SSH) phonons with frequency $ω$ and EPC constant $λ$ can induce AF ordering for a wide range of phonon frequency $ω>ω_c$.

description: We present the fundamentals of geometrothermodynamics, an approach to study the properties of thermodynamic systems in terms of differential geometric concepts. It is based, on the one hand, upon the well-known contact structure of the thermodynamic phase space and, on the other hand, on the metric structure of the space of thermodynamic equilibrium states. In order to make these two structures compatible we introduce a Legendre invariant set of metrics in the phase space, and demand that their pullback generates metrics on the space of equilibrium states. We show that Weinhold's metric, which was introduced {\it ad hoc}, is not contained within this invariant set. We propose alternative metrics which allow us to redefine the concept of thermodynamic length in an invariant manner and to study phase transitions in terms of curvature singularities.

description: The human brain prioritises relevant sensory information to perform different tasks. Enhancement of task-relevant information requires flexible allocation of attentional resources, but it is still a mystery how this is operationalised in the brain. We investigated how attentional mechanisms operate in situations where multiple stimuli are presented in the same location and at the same time. In two experiments, participants performed a challenging two-back task on different types of visual stimuli that were presented simultaneously and superimposed over each other. Using electroencephalography and multivariate decoding, we analysed the effect of attention on the neural responses to each individual stimulus. Whole brain neural responses contained considerable information about both the attended and unattended stimuli, even though they were presented simultaneously and represented in overlapping receptive fields. As expected, attention increased the decodability of stimulus-related information contained in the neural responses, but this effect was evident earlier for stimuli that were presented at smaller sizes. Our results show that early neural responses to stimuli in fast-changing displays contain remarkable information about the sensory environment but are also modulated by attention in a manner dependent on perceptual characteristics of the relevant stimuli. Stimuli, code, and data for this study can be found at https://osf.io/7zhwp/.

description: Background: Long-term care (LTC) patients have high needs for care and are at increased risk when transferred to the emergency department (ED). Objective: This thesis evaluates how paramedics can provide enhanced care to LTC patients, avoiding ED visits. Methods: We completed a systematic review, a national survey, and a health records review. We systematically reviewed existing programs in LTCs seeking to avoid ED visits, assessed program needs through surveying paramedic services, and determined what conditions could be treated by paramedics at the LTC, with a health records review. Results: We found programs reducing ED visits and hospitalizations from LTC patients. Few paramedic services have such community paramedic programs; most would welcome them. Community paramedics could treat 11% of LTC patients on-site, avoiding an ED visit, within current emergency paramedics medical directives. Conclusion: Community paramedics can reduce ED visits and hospitalizations from LTC patients. However, there are barriers to program implementation.
The genetic and molecular analysis of the mfs(2)31 locus in Drosophila melanogaster : a novel suppressor of position-effect variegation
Creators: name: Whitehead, Ian P.
Publisher: name: University of British Columbia
Year: 2008

description: Position-effect variegation (PEV) is the variable inactivation of a euchromatic gene which has been moved, by way of a chromosomal rearrangement, into a heterochromatic environment. The transcriptional repression at the variegating locus is thought to be a consequence of inappropriate packaging of the euchromatin asheterochromatin. Second site mutations which modify the PEV phenotype (Su(var)s and E(var)s), identify loci which encode non-histone chromosomal proteins. Although the majority of mutations which modify PEV exhibit a dominant phenotype, rare recessives u(var) mutations have been reported. This study describes a locus which is identified by one such recessive mutation, mfs(2)31. A cytogenetic analysis of subdivisions 31D-E was undertaken to determine the precise location of the mfs(2)31 locus and to isolate additional alleles. Five new deficiencies and 123 new lethal mutations were induced, allowing for the partitioning of 31D-E intosix cytological subintervals. The mfs(2)31 gene was localized todistal 31E in an interval containing nine lethal complementation groups. Three new mfs(2)31 alleles were recovered, one of whichwas isolated in a screen for P element insertions. The new alleles of mfs(2)31 were used for a phenotypic analysis of the locus. Strong alleles that were lethal as homozygotes died in the larval phase, while weaker alleles exhibited the previously described bristle, sterility and su(var)phenotypes. Larval, pupal and adult functions were defined for the locus. Although no dominant phenotypes were observed, surviving heteroallelic combinations suppressed PEV in a variety of variegating backgrounds. When the weak, P-induced, allele was outcrossed in a dysgenic background, all the mfs(2)31 phenotypes, including suppression of PEV, were co-reverted. An in situhybridization to salivary gland polytene chromosomes revealed a P element in distal 31E of this strain. The P element, located in distal 31E, was cloned from thedysgenic mfs(2)31 allele. This element is responsible for the reduced transcription of a 1.2 kb message which is expressed throughout development. Wild-type levels of transcription are restored at this locus in revertants of the mfs(2)31 phenotype. The predicted amino acid sequence, as determined from a cDNA analysis, reveals similarities with a mouse microtubule-associated protein and mammalian histone H1.

description: We consider projection methods for the estimation of the cumulative distribution function under interval censoring, case 1. Such censored data also known as current status data, arise when the only information available on the variable of interest is whether it is greater or less than an observed random time. Two types of adaptive estimators are investigated. The first one is a two-step estimator built as a quotient estimator. The second estimator results from a mean square regression contrast. Both estimators are proved to achieve automatically the standard optimal rate associated with the unknown regularity of the function, but with some restriction for the quotient estimator. Simulation experiments are presented to illustrate and compare the methods.

description: Nonlinear metamaterials show potential for realizing flat nonlinear optical devices but generally lack in terms of achievable conversion efficiencies. Recent work has focused on enhancing nonlinear processes by utilizing high quality factor resonances, such as collective responses known as surface lattice resonances (SLRs) taking place in periodic metal nanoparticle arrays. Here, we investigate how the dispersive nature of SLRs affects the nonlinear responses of SLR-supporting metasurfaces. Particularly, we measure second-harmonic generation from aluminum nanoparticle arrays and demonstrate that by tilting the sample along two orthogonal directions, the sample can be made multiply-resonant for several pump and second-harmonic signal wavelength combinations. Characterized metasurfaces are estimated to exhibit a second-order susceptibility value of 0.40 pm/V, demonstrating aluminum as a potential material for nonlinear metasurfaces.

More specifically, the main objective of this qualitative research was to enrich and strengthen the interpretation of the results of the integration programs in regular school in order to highlight the benefits of these sections for both students and teachers but also to contribute to the improvement intervention programs through the proposals of teachers in general schools integration classes. Data analysis was done with the interpretive phenomenological analysis. The results show the need for the formulation and implementation of individualized programmatic integration interventions in general schools taking into account the views, perceptions and attitudes of teachers for the integration classes and the motives, self-perception and self-efficacy of children with special educational needs .These results are consistent with previous research showing that the integration classes is not an easy one-dimensional case and contributing to the literature on the implementation of integration programs in the general school.

description: We present a new method, fan-beam modulation, for observing weak extended x-ray sources with the Reuven Ramaty High-Energy Solar Spectroscopic Imager (RHESSI). This space-based solar x-ray and gamma-ray telescope has much greater sensitivity than previous experiments in the 3-25 keV range, but is normally not well suited to detecting extended sources since their signal is not modulated by RHESSI's rotating grids. When the spacecraft is offpointed from the target source, however, the fan-beam modulation time-modulates the transmission by shadowing resulting from exploiting the finite thickness of the grids. In this paper we detail how the technique is implemented and verify its consistency with sources with clear known signals that have occurred during RHESSI offpointing: microflares and the Crab Nebula. In both cases the results are consistent with previous and complementary measurements. Preliminary work indicates that this new technique allows RHESSI to observe the integrated hard x-ray spectrum of weak extended sources on the quiet Sun.

description: Στόχος της εργασίας είναι ο εντοπισμός των βέλτιστων δρομολογίων που πρέπει να κάνει καθημερινά ένας οδηγός της εταιρίας SteriMed στην ευρύτερη περιοχή της Θεσσαλονίκης. Ο κάθε οδηγός έχει ένα συγκεκριμένο σημείο εκκίνησης το οποίο είναι το εργοστάσιο της εταιρείας, και ένα δρομολόγιο με διαφορετικά σημεία επίσκεψης κάθε μέρα, το οποίο θα πρέπει να ακολουθήσει. Με τη βοήθεια της γλώσσας προγραμματισμού Lindo, κωδικοποιήσαμε τα μοντέλα γραμμικού προγραμματισμού και βρήκαμε λύσεις στο πρόβλημα του περιοδεύοντος πωλητή. Έτσι, βρήκαμε τη συνολική βέλτιστη απόσταση που χρειάζεται να κάνει ένας οδηγός της εταιρίας SteriMed, από το σημείο εκκίνησής του (εργοστάσιο στη Σίνδο), στις επισκεπτόμενες υγειονομικές μονάδες, και πάλι πίσω στο σημείο εκκίνησής του. Η σημαντικότερη συνεισφορά της παρούσας έρευνας, είναι τόσο η μείωση του χρόνου των καθημερινών δρομολογίων των οδηγών, όσο και αύξηση του αριθμού των υγειονομικών μονάδων που μπορούν να εξυπηρετηθούν σε μια ημέρα, σε συνδυασμό με τη μείωση του κόστους.
description: The aim of this paper is to identify the best route that should take a driver of the company SteriMed in the region of Thessaloniki. Each driver has a specific starting point which is the company's factory, and a route to visit different places each day, which he should follow. Using the Software Lindo, we encode the linear programming models and found solutions to the traveling salesman problem. So, we found the overall optimal distance needs to do a driver of SteriMed, from its starting point (factory in Sindos) for visiting health units, and back to its starting point. The most important contribution of this research is both to reduce time of daily trips made by drivers, as well as increasing the number of health units that can be served in a day, combined with cost reduction.

description: HO Puppis (HO Pup) was considered as a Be-star candidate based on its gamma-Cassiopeiae-type light curve, but lacked spectroscopic confirmation. Using distance measured from Gaia Data Release 2 and the spectral-energy-distribution (SED) fit on broadband photometry, the Be-star nature of HO Pup is ruled out. Furthermore, based on the 28,700 photometric data points collected from various time-domain surveys and dedicated intensive-monitoring observations, the light curves of HO Pup closely resemble IW And-type stars (as pointed out in Kimura et al. 2020a), exhibiting characteristics such as quasi-standstill phase, brightening, and dips. The light curve of HO Pup displays various variability timescales, including brightening cycles ranging from 23 to 61 days, variations with periods between 3.9 days and 50 minutes during the quasi-standstill phase, and a semi-regular ~14-day period for the dip events. We have also collected time-series spectra (with various spectral resolutions), in which Balmer emission lines and other expected spectral lines for an IW And-type star were detected (even though some of these lines were also expected to be present for Be stars). We detect Bowen fluorescence near the brightening phase, and that can be used to discriminate between IW And-type stars and Be stars. Finally, despite only observing for four nights, the polarization variation was detected, indicating that HO Pup has significant intrinsic polarization.

description: This paper forms part of a larger international project on understanding the rights of the child and developing functional comparative methodologies for assessing approaches recognising the autonomy of a child. As a starting point, it trials a method across the Australian states and territories. The paper will explore the divergence in approaches to the legal recognition of the autonomy of the child. Although the method is ultimately intended for international application in a larger ongoing/future study, it has been adapted for use in the Australian state/federal systems as an initial methodological trial. The method as adopted for this analysis will compare a range of legal age-based distinctions such as the age of criminal responsibility, minimum school leaving age, minimum age for the consumption of alcohol, tobacco and obtaining a driver’s licence, the age for sexual consent both with age- based peers and adults, and the ability to independently receive medical treatment and legal counsel, as well as assessments of the extent of children’s rights, such as legal involvement and consultation rights. The article will analyse the utility of the proposed methodology for international comparisons of the legal autonomy of the child. It will also comment upon the challenges in understanding and recognising the legal autonomy of the child in a federal jurisdiction with distinctions between internal jurisdictions. It will conclude with observations on the function of a yardstick for the comparison of rights of a child generally, as well as observations on the results of the applied method in Australia.

description: This publication presents a philosophical and ontotechnological response to the current crisis in intellectual property systems, as recently highlighted by Jack Dorsey. Rooted in the symbolic architecture of the XChronos OS, it proposes a shift from data-centered systems to experiential, time-conscious infrastructures. The work defends the licensing of symbolic systems under ethical and open principles, positioning subjective time and conscious presence as foundations for a new human–machine interaction paradigm.

Η χρήση της ακουστικής μικροσκοπίας στα αρχαιολογικά ευρήματα, αν και σχετικά νέα, έχει μεγάλο πεδίο εφαρμογών στο τομέα της μελέτης της δομής των ευρημάτων, στον έλεγχο της κατάστασης διατήρησης τους, καθώς και στην εφαρμογή των υλικών συντήρησης. Συγκεκριμένα, η χρησιμότητα μιας τέτοιας, μη καταστρεπτικής μεθοδολογίας, καθίσταται απαραίτητη στις περιπτώσεις που η διαδικασία της δειγματοληψίας είναι εκ των πραγμάτων απαγορευτική. Τέλος, η μελέτη της τεχνολογίας κατασκευής των ψηφίδων με τις τεχνικές XRF και FTIR, ανέδειξαν τη μεθοδολογία κατασκευής των ψηφίδων, συμβάλλοντας και εμπλουτίζοντας με αυτόν το τρόπο την παγκόσμια βάση δεδομένων.
description: This thesis has to do with the study of the 3D structure of glass mosaic tesserae, with or without gold leaf, using the method of acoustic microscopy. Moreover, it was examined the manufacturing technology of glass mosaic tesserae using the method of X-ray fluorescence spectroscopy and the infrared Fourier transform spectroscopy (FTIR). The mosaic tesserae came from the archaeological site of Dion and the experimental part of the thesis held in Ormylia Foundation, which is the base of the Art Diagnostic Centre. The use of the acoustic microscopy in archaeological findings, although relatively new, it is widely applied in the study of the structure of the archaeological findings, in their condition control and in the implementation of the conservation materials. Furthermore, the use of such non-destructive methodology becomes even more important in cases in which the sampling process is actually prohibited. To conclude, the study of the construction technology of the tesserae with the techniques XRF and FTIR, revealed the method which the mosaic tesserae is manufactured,, enriching and contributing in this way to the global database.
