description: Σκοπός της διατριβής ήταν η μελέτη του πολέμου των Φώκλαντ, μιας πολεμικής σύγκρουσης μεταξύ Μεγάλης Βρετανίας και Αργεντινής που ξεκίνησε την άνοιξη του 1982, διήρκησε δέκα εβδομάδες αλλά αποτέλεσε ένα από τα σημαντικότερα γεγονότα του 20ου αιώνα. Παρουσιάστηκε το καθεστώς κυριαρχίας που υφίστατο στα Φώκλαντ μέχρι το 1982, οι συνεχείς διεκδικήσεις της Αργεντινής επί αυτών, όπως επίσης η απόφαση της εν τέλει να εισβάλει και η βρετανική αντίδραση. Στη συνέχεια αναλύθηκαν οι παράγοντες που συνέθεσαν την έκβαση του πολέμου, τόσο μέσω της παρουσίασης των στρατιωτικών μέσων που είχαν στη διάθεσή τους οι δύο πλευρές, όσο και από τη σκοπιά των διπλωματικών διαπραγματεύσεων που λάμβαναν χώρα με την ελπίδα μιας ειρηνικής επίλυσης της κρίσης. Αναφερθήκαμε επίσης στην προετοιμασία των δύο πλευρών για τον πόλεμο και στις στρατιωτικές επιχειρήσεις, από τη βύθιση του αργεντινού καταδρομικού Βelgrano μέχρι την απόβαση στο Σαν Κάρλος, την κατάληψη του Ντάργουϊν και Γκους Γκρην, με τους Βρετανούς να βγαίνουν θριαμβευτές του πολέμου. Η μελέτη ολοκληρώθηκε αφενός με τον απολογισμό της έκβασης του πολέμου και τις συνέπειες αυτού για κάθε πλευρά και αφετέρου με μια σύντομη επισκόπηση, η οποία σκοπό είχε την ανακεφαλαίωση καίριων σημείων που επηρέασαν την έκβαση του πολέμου.
description: The aim of the present thesis was the study of the Falklands War, a military conflict between Great Britain and Argentina, which started in the spring of 1982, lasted only ten weeks but is known as one of the most important incidents of the 20th century. We presented the issue of sovereignty that existed in the Falkland Islands up until 1982, the constant claims of Argentina, her decision to invade and the British response. Then we examined the factors which led to the British victory by analyzing the military means of both sides and the diplomatic negotiations that took place with the hope of a pacific solution to the crisis. Furthermore, we presented the preparations held by both sides in order to be in position to participate in military operations, as well as the events that followed the sunk of the Argentine warship Belgrano, the landing in San Carlos, the battles of Goose Green and finally the dominance of the British forces. The thesis was completed with a generalizability of findings, a brief review on the effects of the conflict for both sides, which aim was to recap the main factors that led to the British triumph.

description: The dominant source of electromagnetic energy in the Universe today (over ultraviolet, optical and near-infrared wavelengths) is starlight. However, quantifying the amount of starlight produced has proven difficult due to interstellar dust grains which attenuate some unknown fraction of the light. Combining a recently calibrated galactic dust model with observations of 10,000 nearby galaxies we find that (integrated over all galaxy types and orientations) only (11 +/- 2)% of the 0.1 micron photons escape their host galaxies; this value rises linearly (with log(lambda)) to (87 +/- 3)% at 2.1 micron. We deduce that the energy output from stars in the nearby Universe is (1.6+/-0.2) x 10^{35} W Mpc^{-3} of which (0.9+/-0.1) x 10^{35} W Mpc^{-3} escapes directly into the inter-galactic medium. Some further ramifications of dust attenuation are discussed, and equations that correct individual galaxy flux measurements for its effect are provided.

description: Based on the archival Hubble Space Telescope images, we have performed stellar photometry for 18 dwarf galaxies. Branches of young and old stars are seen on the constructed Hertzsprung-Russell diagrams. Using the photometry of red giants and applying the TRGB method, we have determined accurate distances for all 18 galaxies for the first time. The galaxies AGC238890 and AGC747826 have minimum ($D$ = 5.1 Mpc) and maximum ($D$ = 12.0 Mpc) distances, respectively. The distances to the remaining galaxies lie within this range. Low-metallicity galaxies have been identified by measuring the color indices of the red giant branch: AGC102728, AGC198691, AGC205590, AGC223231, AGC731921, and AGC747826. We have determined the distance to AGC198691 with a record low metallicity. Since AGC223254, AGC229053, AGC229379, AGC238890, AGC731921, and AGC742601 are projected onto the Virgo cluster of galaxies, the distances estimated by us together with the velocities of these galaxies measured previously at Arecibo can be used to refine the effect of galaxy infall to the Virgo cluster.

Formation of closed timelike curves in a composite vacuum/dust asymptotically-flat spacetime

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We present a new asymptotically-flat time-machine model made solely of vacuum and dust. The spacetime evolves from a regular spacelike initial hypersurface S and subsequently develops closed timelike curves. The initial hypersurface S is asymptotically flat and topologically trivial. The chronology violation occurs in a compact manner; namely the first closed causal curves form at the boundary of the future domain of dependence of a compact region in S (the core). This central core is empty, and so is the external asymptotically flat region. The intermediate region surrounding the core (the envelope) is made of dust with positive energy density. This model trivially satisfies the weak, dominant, and strong energy conditions. Furthermore it is governed by a well-defined system of field equations which possesses a well-posed initial-value problem.

description: In natural languages, words are used in association to construct sentences. It is not words in isolation, but the appropriate combination of hierarchical structures that conveys the meaning of the whole sentence. Neural networks can capture expressive language features; however, insights into the link between words and sentences are difficult to acquire automatically. In this work, we design a deep neural network architecture that explicitly wires lower and higher linguistic components; we then evaluate its ability to perform the same task at different hierarchical levels. Settling on broad text classification tasks, we show that our model, MHAL, learns to simultaneously solve them at different levels of granularity by fluidly transferring knowledge between hierarchies. Using a multi-head attention mechanism to tie the representations between single words and full sentences, MHAL systematically outperforms equivalent models that are not incentivized towards developing compositional representations. Moreover, we demonstrate that, with the proposed architecture, the sentence information flows naturally to individual words, allowing the model to behave like a sequence labeller (which is a lower, word-level task) even without any word supervision, in a zero-shot fashion.

description: In this study, we conducted a large-scale molecular biology analysis of pregnancy phenotypes based on genotype data from nearly 40,000 pregnant women and over 110 clinical measurements. Genome-wide association analysis identified novel loci for numerous phenotypes and also provided the first GWAS results for several phenotypes. Functional enrichments and relevant tissues/cell types for multiple pregnancy phenotypes (e.g., birth weight, twin gestation) were identified for the first time. In terms of both sample size and the variety of phenotypes, our work is one of the largest population genetic studies of pregnancy phenotypes. We believe that this study will provide a valuable reference for exploring the genetic background of pregnancy phenotypes and also for further research on pregnancy-related diseases.

description: The prospect of relativistic jets exhibiting complex morphologies as a consequence of geodetic precession has long been hypothesised. We have carried out a 3D hydrodynamics simulation study varying the precession cone angle, jet injection speed and number of turns per simulation time. Using proxies for the radio emission we project the sources with different inclinations to the line of sight to the observer. We find that a number of different precession combinations result in characteristic `X' shaped sources which are frequently observed in radio data, and some precessing jet morphologies may mimic the morphological signatures of restarting radio sources. We look at jets ranging in scale from tens to hundreds of kiloparsecs and develop tools for identifying known precession indicators of point symmetry, curvature and jet misalignment from the lobe axis and show that, based on our simulation sample of precessing and non-precessing jets, a radio source that displays any of these indicators has a 98% chance of being a precessing source.

description: In this paper we extend the bosonic $D$-brane action in D=10 obtained by duality from the D=11 membrane wrapped on $S^1$ to an SU(2) non abelian system. This system presents only first class constraints, whose algebra closes off-shell and generalizes the algebra of diffeomorphisms of the $D2$-brane to include non abelian symmetry generators. From the SU(2) $D$-brane action, we also obtain the SU(2) Born-Infeld theory by performing a covariant reduction to a flat background. This calculation agrees up to fourth order with the result obtained from the superstring amplitudes and gives an alternative approach to analyze non-abelian Born-Infeld theories.

description: In this study, we implemented the largest population genetic study of GDM in a Chinese population to date. Genome-wide association analysis of glycemic traits recapitulated known genes, and also identified several novel genes. Further functional pathway analysis enriched these candidate genes to pathways related to glucose metabolism and, interestingly, also to pathways related to hormone levels and postnatal traits (e.g., birth weight). To our knowledge, this is the first time that gestational diabetes and postnatal outcome have been linked at the genetic level. In addition to this, the logistic regression and genetic correlation analysis emphasized the major connection of early plasma glucose to GDM, suggesting the necessity of monitoring glucose levels in the first trimester. Considering both clinical measurements and genetic components, we constructed predictive models for early detection of GDM. We believe that our study will certainly become an important reference for population genetic study of GDM and will have important implications for elucidating the genetic mechanisms of GDM.

description: This dissertation examines the issue of termination of the franchise (franchising agreement) and in particular the specific issues arising from its termination. Specifically, all the forms of termination of the franchising agreement are studied, as well as the consequences of its termination, the obligations of the parties after the termination of the contract, the protection of any investment made by the franchisee during the contract and which has not yet recovered upon termination of the contract, the ability of the franchisee to claim compensation by the proportional implementation of the article 9 of the presidential decree 219/1991 on commercial agents and, finally, the prohibition of competition after the termination of the contract. Before examining these issues, it was considered appropriate to perform an overall general overview of the contract, briefly studying the meaning, its features, its legal nature, the formation of relations of the parties, the rights and obligations of the parties, and the advantages and disadvantages of franchising as an economic institution.

description: AGL16 bound to promoters of more than 2000 genes via CArG-box motifs with high similarity to that of SOC1 in Arabidopsis thaliana. Approximately seventy flowering genes involved in multiple pathways were potential targets of AGL16. AGL16 formed a protein complex with SOC1 and shared a common set of targets. Intriguingly, only a limited number of genes were differentially expressed in the agl16-1 loss-of-function mutant. However, in the soc1-2 knockout background, AGL16 repressed and activated the expression of 375 and 182 genes, respectively, with more than a quarter bound by AGL16.

description: Από τις αρχές του 4ου αιώνα μ.Χ, οπότε και ο Κωνσταντίνος έγινε κυρίαρχος σ’ ολόκληρη τη Ρωμαϊκή Αυτοκρατορία, ο Χριστιανισμός εξαπλώνεται με γοργούς ρυθμούς και σύντομα γίνεται η επίσημη θρησκεία. Το κέντρο βάρους της Αυτοκρατορίας στους αμέσως επόμενους αιώνες, μεταφέρεται στην Ανατολή, όπου ιδρύεται και η νέα πρωτεύουσα, η Κωνσταντινούπολη. Οι σχέσεις των Εθνικών, δηλαδή των υποστηρικτών του παγανισμού, και των Χριστιανών κατά τη διάρκεια της περιόδου αυτής στην Ανατολή αποτελούν το αντικείμενο μελέτης της παρούσας εργασίας. Το πρώτο κεφάλαιο ασχολείται με την αντιμετώπιση των Εθνικών από τους Χριστιανούς πλέον αυτοκράτορες και τα μέτρα που πάρθηκαν εναντίον τους. Το δεύτερο αναλύει τις κοινωνικές παραμέτρους των σχέσεων αυτών και το ρόλο που έπαιξαν οι εθνικές και κοινωνικές διαφοροποιήσεις που υπήρχαν στα πλαίσια της αυτοκρατορίας. Το τρίτο κεφάλαιο αναφέρεται στην κατάσταση του Χριστιανισμού και του παγανισμού εκείνη την εποχή. Ιδιαίτερη αναφορά γίνεται στο ρόλο που έπαιζε η μαγεία και η λατρεία των δαιμόνων, όπως και στην αντιμετώπιση που είχαν από τη Χριστιανική Εκκλησία. Τέλος, το τέταρτο κεφάλαιο εντοπίζει τις συγκρούσεις που κατά καιρούς προκλήθηκαν ανάμεσα σε Εθνικούς και Χριστιανούς και τα αίτια που τις προκάλεσαν. Η διδασκαλία των Πατέρων της Εκκλησίας για την ανοχή απέναντι στους μη-Χριστιανούς, δείχνει ότι τα αίτια που προκάλεσαν αυτές τις συγκρούσεις δεν ήταν τόσο θρησκευτικά, αλλά συνήθως υποκρύπτονταν πίσω απ’ αυτές πολιτικοί ή κοινωνικοοικονομικοί παράγοντες.
description: Since the beginning of the 4th century AD, when Constantine became dominant throughout the Roman Empire, Christianity spread rapidly and soon became the official religion. The center of gravity of the Empire in the following centuries, moved to the East, where the new capital, Constantinople was founded. The subject of the present study is the relations between Pagans, supporters of paganism, and the Christians during this period in the East. The first chapter deals with the treatment of Pagans by Christian emperors and the measures which were taken against them. The second analyzes the social aspects of these relations and the role that the national and social differences existing within the Empire played. The third chapter refers to the situation of Christianity and paganism at that time. Particular reference is made to the role that the witchcraft and the worship of demons played, including the opposition of the Christian Church. Finally, the fourth chapter identifies the conflicts that occasionally were caused between the Pagans and the Christians as well as the reasons that caused them. The teaching of the Church Fathers for tolerance toward non-Christians, shows that the reasons behind these conflicts were mainly not religious, but usually political or socioeconomic factors were concealed behind them.

description: LS 5039 is the only X-ray binary persistently detected at TeV energies by the Cherenkov HESS telescope. It is moreover a gamma-ray emitter in the GeV and possibly MeV energy ranges. To understand important aspects of jet physics, like the magnetic field content or particle acceleration, and emission processes, such as synchrotron and inverse Compton (IC), a complete modeling of the multiwavelength data is necessary. LS 5039 has been detected along almost all the electromagnetic spectrum thanks to several radio, infrared, optical and soft X-ray detections. However, hard X-ray detections above 20 keV have been so far elusive and/or doubtful, partly due to source confusion for the poor spatial resolution of hard X-ray instruments. We report here on deep (300 ksec) serendipitous INTEGRAL hard X-ray observations of LS 5039, coupled with simultaneous VLA radio observations. We obtain a 20-40 keV flux of 1.1 +/- 0.3 mCrab (5.9 (+/-1.6) X 10^{-12} erg cm^{-2} s^{-1}), a 40-100 keV upper limit of 1.5 mCrab (9.5 x 10^{-12} erg cm^{-2}s^{-1}), and typical radio flux densities of about 25 mJy at 5GHz. These hard X-ray fluxes are significantly lower than previous estimates obtained with BATSE in the same energy range but, in the lower interval, agree with extrapolation of previous RXTE measurements. The INTEGRAL observations also hint to a break in the spectral behavior at hard X-rays. A more sensitive characterization of the hard X-ray spectrum of LS 5039 from 20 to 100 keV could therefore constrain key aspects of the jet physics, like the relativistic particle spectrum and the magnetic field strength. Future multiwavelength observations would allow to establish whether such hard X-ray synchrotron emission is produced by the same population of relativistic electrons as those presumably producing TeV emission through IC.

description: We present the quasar luminosity function at $z \sim 5$ derived from the optical wide-field survey data obtained as a part of the Subaru strategic program (SSP) with Hyper Suprime-Cam (HSC). From $\sim$81.8 deg$^2$ area in the Wide layer of the HSC-SSP survey, we selected 224 candidates of low-luminosity quasars at $z \sim 5$ by adopting the Lyman-break method down to $i = 24.1$ mag. Based on our candidates and spectroscopically-confirmed quasars from the Sloan Digital Sky Survey (SDSS), we derived the quasar luminosity function at $z \sim 5$ covering a wide luminosity range of $-28.76 < M_{\rm 1450} < -22.32$ mag. We found that the quasar luminosity function is fitted by a double power-law model with a break magnitude of $M^{*}_{1450} = -25.05^{+0.10}_{-0.24}$ mag. The inferred number density of low-luminosity quasars is lower, and the derived faint-end slope, $-1.22^{+0.03}_{-0.10}$, is flatter than those of previous studies at $z \sim 5$. A compilation of the quasar luminosity function at $4 \leq z \leq 6$ from the HSC-SSP suggests that there is little redshift evolution in the break magnitude and in the faint-end slope within this redshift range, although previous studies suggest that the faint-end slope becomes steeper at higher redshifts. The number density of low-luminosity quasars decreases more rapidly from $z \sim 5$ to $z \sim 6$ than from $z \sim 4$ to $z \sim 5$.

description: Partial-wave analyses (PWA) are an essential tool for studying resonance structures in decays with hadronic multi-body final states. For several years, more model-independent approaches to such analyses have been used for various decay final states. However, up to now, these methods have mostly been applied to sub-sets of partial waves, also called freed waves. In this article, we explore possibilities and limitations of extended model-independent approaches. We systematically apply various different fit models to the analysis of pseudo data sets, to study both the impact of the mathematical description used for the freed waves and the choice of simultaneously freed waves. We can show that suitable methods exist, which lift restrictions to only sub-sets of freed partial waves and demonstrate hidden caveats present in previous works.

description: An extraordinary event took place recently in Ireland. A group of independent and professional researchers met to discuss an old heterodox topic with important consequences in astrophysics and, especially, in cosmology: possible causes of the redshifts in the spectra of astrophysical objects other than a Doppler or expanding universe mechanism. Many decades of work have been devoted to this kind of research, most of it forgotten by the greater part of the astrophysical community nowadays. But the question is still open, the debate is still alive, as was shown by the participants in the present Workshop. There is no smoke without fire, and the existence of many facts and theories on alternative origins of redshifts may point to some new pathways in physics that deserve further attention. This was precisely the aim of this meeting. (...)

description: Characterizing cell features of germinating seeds is essential for understanding the complex biological functions of different embryonic cells in regulating seed vigor and seedling establishment. In this study, we performed spatially enhanced resolution omics (Stereo-seq) and single-cell RNA sequencing (scRNA-seq) to capture spatially resolved single-cell transcriptomes of germinating rice embryos. An automated cell-segmentation model was developed based on deep-learning to accommodate the analysis requirements. The spatial transcriptome revealed known and novel cell types of rice embryo, including two new scutellum cell types. The temporal transcriptome revealed the expression dynamics of genes in different types of embryonic cells during the time course of seed germination and the key genes, particularly related to nutrient metabolism and biosynthesis and signaling of phytohormonesand were reprogrammed in a cell-type-specific manner. Our study provides a panoramic spatiotemporal transcriptome of rice embryo and a novel methodology for exploring the roles of different embryonic cells in seed germination.

description: Ο εσωτερικός έλεγχος αποτελεί από ετών λειτουργία που συμβάλει σε μεγάλο βαθμό στην βελτίωση της απόδοσης των οργανισμών που τον εφαρμόζουν. Σε ακαδημαϊκό και πρακτικό επίπεδο έχει μελετηθεί διεξοδικά και έχουν διατυπωθεί αναλυτικά μεθοδολογίες εφαρμογής των κανόνων του ώστε να καλύπτουν τις ιδιαιτερότητες του συνόλου του εύρους των διαφορετικού χαρακτήρα οργανισμών σε παγκόσμιο επίπεδο. Στη περίπτωση των οργανισμών του δημόσιου τομέα στην Ελλάδα, αν και έχει προβλεφθεί νομοθετικά η λειτουργία μονάδων εσωτερικού ελέγχου, έχει υστερήσει χρονικά η οργάνωση τους. Με την παρούσα εργασία, αφού περιγράψουμε την έννοια και την μεθοδολογία του εσωτερικού ελέγχου γενικά, θα εξετάσουμε μία συγκεκριμένη περίπτωση φορέα άσκησης εσωτερικού ελέγχου σε δημόσιο οργανισμό ώστε να εξάγουμε συμπεράσματα για την σημασία του ρόλου του εσωτερικού ελέγχου ευρύτερα στους δημόσιους οργανισμούς.
description: Internal audit is a function that is long proven to greatly contribute in improving the performance of organizations applying it. In academic and practical level it has been extensively studied and detailed methodologies have been developed for implementing rules to cover specifically the whole range of organizations of different nature worldwide. In the case of public sector organizations in Greece, although legislative action for the development of internal audit units has been taken, a delay in their formulation is observed. In the present paper, after describing the concept and methodology of internal audit generally, we will examine a particular case of a body of internal control in a public organisation aiming to draw conclusions widely about the importance of the role of the internal audit public organizations.

description: Στόχο της παρούσας εργασίας αποτέλεσε η συγκριτική μελέτη του εκπαιδευτικού προγράμματος και των κοινωνικών αλληλεπιδράσεων παιδιών με μέτρια νοητική ανεπάρκεια που φοιτούν σε ειδικά σχολεία και σχολεία γενικής αγωγής στην Αγγλία. Για το σκοπό αυτό, συλλέχθηκαν ποσοτικά και ποιοτικά δεδομένα μέσω ερωτηματολογίων προς τους εκπαιδευτικούς συνολικά 30 μαθητών, αλλά και παρατηρήσεων κατά το διάλειμμα. Σύμφωνα με τα αποτελέσματα που προέκυψαν, τα παιδιά που φοιτούν σε γενικά σχολεία φαίνεται να υπερτερούν σημαντικά σε σχέση με τους μαθητές ειδικών σχολείων στη συχνότητα των θετικών συμπεριφορών που επιδεικνύουν κατά το μάθημα, ενώ οι διαφορές των αλληλεπιδράσεών τους κατά το μάθημα δεν διέφεραν σημαντικά. Επιπλέον, όσον αφορά τους εκπαιδευτικούς στόχους, οι εκπαιδευτικοί των ειδικών σχολείων φάνηκε να είναι περισσότερο προσανατολισμένοι σε στόχους για τη βελτίωση της συμπεριφοράς και κατάκτησης δεξιοτήτων καθημερινής ρουτίνας, σε αντίθεση με τους εκπαιδευτικούς των γενικών σχολείων, οι οποίοι έδωσαν έμφαση στους μαθησιακούς στόχους και τη διαφοροποίησή τους ώστε να ανταποκρίνονται στις ανάγκες των μαθητών με μέτριες νοητικές δυσκολίες. Καθώς το δείγμα της συγκεκριμένης έρευνας θεωρείται μικρό σε αριθμό, κρίνεται σημαντική η διενέργεια μεγαλύτερων ερευνών πάνω στο συγκεκριμένο θέμα, με στόχο τη γενίκευση των αποτελεσμάτων.
description: The aim of this study was to compare the educational programmes and the social interactions between students with moderate intellectual disability in special schools and students with moderate intellectual disability in mainstream schools in the UK. For this purpose, both qualitative and quantitative data had been collected through questionnaires to the teachers of 30 students in total, as well as through observations during the break times. According to the results that came out, the children who study in mainstream schools seem to predominate significantly in comparison to the children who study in special schools in relation to the frequency of their positive behaviours during the lesson, while the differences in their interactions had not been differed considerably. Moreover, in relation to the educational targets, the special school teachers seem more behavioural and daily routine target orientated, in contrast to the mainstream school teachers, who seemed to pay more attention in the learning targets and how to differentiate them in order to meet the needs of the individual pupils with moderate intellectual disability. Since the sample of the specific study is considered small in size, crucial is believed to be the delivery of bigger studies on the specific theme, helping the generalisation of the results.

description: Η παρούσα μελέτη επιδιώκει να παρουσιάσει την έννοια της πολλαπλής διάκρισης και τα επιμέρους χαρακτηριστικά της, στην αναγνώριση των οποίων συνέβαλε σημαντικά η θεωρία της διαπλοκής των ταυτοτικών χαρακτηριστικών του ανθρώπου, που γεννήθηκε στις Ηνωμένες Πολιτείες της Αμερικής. Η θεωρία αυτή, που εισήχθη στο νομικό χώρο με αφορμή την περιθωριοποίηση –σε επίπεδο προστασίας- των έγχρωμων γυναικών, κατάφερε να επεκταθεί και σε άλλες χώρες και έννομες τάξεις, όπως αυτές του Καναδά και της Ευρωπαϊκής Ένωσης, καθιστώντας ευχερέστερη την κατανόηση της έννοιας της πολλαπλής διάκρισης και την ένταξή της στο νομικό οπλοστάσιο κάθε δικαιικού συστήματος. Σημαντικό εργαλείο στην προσπάθεια της συγκριτικής προσέγγισης των δύο προαναφερθέντων συστημάτων δικαίου όσον αφορά στο φαινόμενο της πολλαπλής διάκρισης υπήρξε το Συγκριτικό Δίκαιο, με τη βοήθεια του οποίου πραγματοποιήθηκε η μελέτη των στοιχείων που προσδιορίζουν τη φυσιογνωμία των εννόμων τάξεων και αναζητήθηκε ο μηχανισμός που κάθε μία από αυτές επιστρατεύει για την αντιμετώπιση του φαινομένου. Ειδικότερα, επιχειρήθηκε η ανεύρεση των σημείων σύγκλισης και απόκλισης μεταξύ των υπό εξέταση έννομων τάξεων, ως προϊόντα του ευρύτερου νομικού, ιστορικού, κοινωνικού, οικονομικού και πολιτικού περιβάλλοντος, βάσει της αξιολόγησης των οποίων διεξήχθησαν ορισμένα συμπεράσματα σχετικά με την αντιμετώπιση του φαινομένου της πολλαπλής διάκρισης.
description: This study presents the idea of multiple discrimination and its special forms which was recognized thanks to the theory of the intersection of a human being’s identity characteristics -first developed in the U.S.A. This theory -introduced in the legal field on the occasion of black women’s marginalization- managed to expand in further countries and judicial systems, like the ones of Canada and the European Union, thus making the comprehension of the content of the idea much easier, as well as enhancing its accession into the judicial arsenal of each system. Nevertheless, an important tool to this comparative approach, as far as the effect of multiple discrimination is concerned, has been no other than the Comparative Law, the methodological nature of which has contributed to the research of all those elements that define the character of a legal system and help to detect the mechanisms set in motion to confront the phenomenon at issue. More precisely, all convergence and divergence points detected between the examined legal systems, in the framework of historical, social, financial and political circumstances, were evaluated and constituted the basis on which the final conclusions on the idea of multiple discrimination were conducted.

Εξετάστηκε, αρχικά, ο λόγος για τον οποίο ο Βιζυηνός εμπίπτει στο πλαίσιο της φιλοσοφικής έρευνας και επιχειρήθηκε,επίσης, μια στοιχειοθέτηση της αισθητικής του θεωρίας μέσα από το θεωρητικό, κατά κύριο λόγο, έργο του. Στη συνέχεια, παρουσιάστηκε αναλυτικά η μορφή και το περιεχόμενο του συνόλου του έργου του με έμφαση στον Ρομαντισμό και τον Νεοπλατωνισμό καθώς και στην πρόσληψή τους από τον Βιζυηνό. Επιπλέον, έγιναν αναφορές σε ζητήματα ψυχολογίας, όπως τα εκθέτει στις μελέτες και τα διηγήματά του. Τέλος, σχολιάστηκαν συνδέσεις με το διανοητικό περιβάλλον της εποχής του, τόσο το ελληνικό όσο και το γερμανικό.
description: The purpose of this research was the attempt to present Georgios M. Vizyenos’,one of the top writers and intellectuals of the 19th centuryin Greece,whole aesthetics. Consideration hasbeen initially taken into the reason why Vizyenos comes under the philosophical inquiry and ithas been also attempted to composehis aesthetic theory mainly through his theoretical works. Then,the form and the content of hiswork in total have been thoroughly presented with emphasis on Romanticism and Neo-Platonism as well as Vizyenos’apprehension of them. In addition, references have been made topsychological topics, as exposed in his studies and short stories. Finally, comments have been made toconnections with the intellectual environment of his time, both Greek and German.

Borges, Pier Damiani e i passati contingenti

description: La discussione medievale sul tema dei futuri contingenti pone al centro dell’attenzione, da un lato, il modo di concepire conoscenza e potenza divine e, dall’altro, lo statuto degli eventi futuri. Pier Damiani, monaco dell’XI secolo, distingue fra la possibilità divina di mutare le conseguenze del passato e quella di produrre un passato interamente diverso. Pedro Damian, protagonista del racconto di Borges, riscatta il suo comportamento giovanile producendo poco alla volta un altro, diverso, passato. La potenza della memoria invece della potenza di Dio.

The Collapse of Bell Determinism

Publisher: name: arXiv
Year: 2006

description: The Bell-Kochen-Specker conditions (BKS) for a deterministic noncontextual hidden-variable model are wonderfully simple to state, deal with just one-dimensional projectors on a Hilbert space H and make no reference to a probabilistic phase space or quantum system. They only ask for an assignment of zero or one to every projector such that the assignment respects orthogonal resolutions of the identity. Various no-go results in the literature show that the pair of statements {BKS is valid; dim H greater than or equal to 3} are inconsistent. Here we show, more radically, that the pair actually contradicts the dimensionality of the space itself, by implying that there can exist at most a single one-dimensional projector acting on H. Our derivation involves only elementary inner product spaces. It is non-probabilistic, inequality-free, state independent, does not use entanglement, and is simultaneously valid in all dimensions three or greater.

description: L’avventura ultraterrena di Dante, definita divina da Boccaccio, si fa in Borges commedia di vita. È soprattutto nell’interpretazione esistenziale del viaggio ultraterreno dantesco che risiede l’irresistibile forza di attrazione dell’ateo Borges per la teologia poetica di Dante, un viaggio alla scoperta di un’umanità, di cui l’incontro con il poeta restituisce affreschi indelebili di grande intensità.

description: Recent studies prove that the analysis of metaphors which are used by teachers when they refer to the teaching process is an important research tool for the study of their personal theory. This article presents the results of a research in a field which studies the serving teachers’ and the future teachers’ points of view concerning teaching and knowledge, through the analysis of their metaphorical speech. From the research results we can con¬clude that the majority of the cross-section teachers expressed metaphorical phrases which indicate traditional perceptions concerning teaching methods and knowledge. These perceptions contrast with the modern tendencies that are promoted by the teacher education and training programmes. In this context, metaphors could become a dynamic tool of a reflective analysis, capable of helping teachers to realize their personal theory, to evaluate it so that they would be able to enrich it and develop it.

description: The presence of a small concentration of in-plane Fe dopants in La$_{1.87}$Sr$_{0.13}$Cu$_{0.99}$Fe$_{0.01}$O$_4$ is known to enhance stripe-like spin and charge density wave (SDW and CDW) order, and suppress the superconducting $T_c$. Here, we show that it also induces highly two-dimensional (2D) superconducting correlations that have been argued to be signatures of a new form of superconducting order, so-called pair-density-wave (PDW) order. In addition, using the resonant soft x-ray scattering, we find that the 2D superconducting fluctuation is strongly associated with the CDW stripe. In particular, the PDW signature first appears when the correlation length of the CDW stripe grows over eight times the lattice unit ($\sim$ 8$a$). These results provide critical conditions for the formation of PDW order.
