description: Ausgehend von der Vielfalt von Forschungs- und Entwicklungsformaten an der Versuchsschule Oberstufen-Kolleg (vgl. den Beitrag von Klewin & Heinrich, S. 7–26 in diesem Band) stellt sich die Frage, weshalb dieser Variantenreichtum sinnvoll oder sogar geboten erscheint. Im vorliegenden Beitrag möchten wir diese spezifische Gemengelage für die Praxisforschung forschungsmethodologisch reflektieren, indem wir die Frage stellen, inwieweit diese Frage nach der Gegenstandsangemessenheit im Rahmen von Praxisforschung nicht einen multiparadigmatischen Ansatz erfordert. Nach einer Problemskizzierung der unterschiedlichen Logiken der Gegenstandsbestimmung im Rahmen von Praxisforschung (Kap. 1) bringen wir als methodologische Perspektive den Ansatz der Multiparadigmatik in Anschlag (Kap. 2). Den Gedanken der Multiparadigmatik aufnehmend stellen wir abschließend (Kap. 3) die Frage, welche Konsequenzen sich daraus für Schulentwicklung, Fortbildung sowie internen und externen Transfer ergeben.

Starting from the diversity of research and development formats at the experimental school Oberstufen-Kolleg (cf. Klewin & Heinrich, pp. 7–26 in this volume), the question arises whether and why this wealth of variants seems sensible or even necessary. In this article, we reflect on this specific situation for practice research in terms of research methodology by asking whether the question of object appropriateness in the context of practice research does not require a multi-paradigmatic approach. After outlining the problems of the different logics of object definition in the context of practice-based research (chapter 1), we will use the multi-paradigmatic approach as a methodological perspective (chapter 2). Taking up the idea of multi-paradigmatics, we conclude (chapter 3) by asking what consequences this has for school development, further training and internal and external transfer.

description: Σκοπός της διπλωματικής εργασίας ήταν η μελέτη της πλατωνικής θεωρίας της δικαιοσύνης, όπως αυτή αναπτύσσεται στην Πολιτεία του Πλάτωνα, και η κριτική που άσκησε ο Karl Popper. Προσεγγίσαμε πολλά από τα ζητήματα που θίγονται στο κείμενο της Πολιτείας, όπως της πλατωνικής ψυχής, των αρετών, της αγωγής, της ευτυχίας και των πολιτευμάτων, επιχειρώντας έτσι μια διεισδυτική έρευνα για την εξαγωγή ασφαλών συμπερασμάτων γύρω από το πολύπλοκο θέμα της δικαιοσύνης. Νωρίτερα, σκιαγραφήσαμε την προσωπικότητα του Πλάτωνα και περιγράψαμε την εποχή στην οποία έζησε και συνέγραψε το έργο του, έχοντας ως στόχο την αξιολόγηση των δεδομένων λαμβάνοντας υπόψη συγκεκριμένες χρονικές συγκυρίες. Στη συνέχεια παρουσιάσαμε αναλυτικά τις θέσεις του Popper τόσο γύρω από το πρόσωπο του ίδιου του Πλάτωνα, όσο και της Πολιτείας του. Αναφερθήκαμε στις κατηγορίες του περί ιστορικισμού, κλειστών κοινωνιών και ολοκληρωτισμού, και εκθέσαμε διεξοδικά την θεωρία του για την ανοιχτή κοινωνία και τους εχθρούς της. Και στην περίπτωση του Popper, προηγουμένως επιχειρήθηκε μια σύντομη αλλά περιεκτική αναφορά στη ζωή του και στο έργο του. Αναφερθήκαμε επιπλέον σε ορισμένες ενδεικτικές κριτικές που ασκήθηκαν από διανοούμενους της Ελλάδας και του εξωτερικού, στην κριτική του Popper για την πλατωνική πολιτική – ολοκληρωτική κατ’ αυτόν – θεωρία. Συμπεράναμε ότι η αλήθεια του ζητήματος βρίσκεται κάπου στο μέσο, αναλόγως με την εποχή και τα κοινωνικά – πολιτικά δεδομένα.
description: The purpose of this thesis was to study the Platonic theory of justice as developed in Plato's Republic, and the criticism of Karl Popper. We approached many of the issues raised in the text of the Republic, as the Platonic soul, the virtues, education, happiness and political systems, attempting with such an intrusive investigation to draw firm conclusions about the complex issue of justice. At first, we outlined the personality of Plato, described the time in which he lived and wrote his work, aiming to evaluate the data while taking into account specific time in which it was written. Then, we presented in detail the positions of Popper, on both Plato and his Republic. We discussed the categories on historicism, closed societies and totalitarianism and reported in detail the theory of the open society and its enemies. In addition, we made a brief but comprehensive reference to the life and work of Popper. We also discussed some indicative criticism from intellectuals in Greece and abroad, on Popper's criticism of Plato's political – totalitarian, according to Popper - theory. Finally, we concluded that the truth of the matter lies somewhere in the middle, depending on the time and the social - political conditions.
Multivariate control charts based on Bayesian state space models

description: This paper develops a new multivariate control charting method for vector autocorrelated and serially correlated processes. The main idea is to propose a Bayesian multivariate local level model, which is a generalization of the Shewhart-Deming model for autocorrelated processes, in order to provide the predictive error distribution of the process and then to apply a univariate modified EWMA control chart to the logarithm of the Bayes' factors of the predictive error density versus the target error density. The resulting chart is proposed as capable to deal with both the non-normality and the autocorrelation structure of the log Bayes' factors. The new control charting scheme is general in application and it has the advantage to control simultaneously not only the process mean vector and the dispersion covariance matrix, but also the entire target distribution of the process. Two examples of London metal exchange data and of production time series data illustrate the capabilities of the new control chart.

description: The HERMES-TP/SP (High Energy Rapid Modular Ensemble of Satellites -- Technologic and Scientific Pathfinder) is an in-orbit demonstration of the so-called distributed astronomy concept. Conceived as a mini-constellation of six 3U nano-satellites hosting a new miniaturized detector, HERMES-TP/SP aims at the detection and accurate localisation of bright high-energy transients such as Gamma-Ray Bursts. The large energy band, the excellent temporal resolution and the wide field of view that characterize the detectors of the constellation represent the key features for the next generation high-energy all-sky monitor with good localisation capabilities that will play a pivotal role in the future of Multi-messenger Astronomy. In this work, we will describe in detail the temporal techniques that allow the localisation of bright transient events taking advantage of their almost simultaneous observation by spatially spaced detectors. Moreover, we will quantitatively discuss the all-sky monitor capabilities of the HERMES Pathfinder as well as its achievable accuracies on the localisation of the detected Gamma-Ray Bursts.

description: We study the locus of dwarf and giant early and late-type galaxies on the Tully-Fisher relation (TFR), the stellar mass Tully-Fisher relation (sTFR) and the so-called baryonic or HI gas+stellar mass Tully-Fisher relation (gsTFR). We show that early-type and late-type galaxies, from dwarfs to giants, trace different yet approximately parallel TFRs. Surprisingly, early-type and late-type galaxies trace a single yet curved sTFR over a range of 3.5 orders of magnitude in stellar mass. Moreover, all galaxies trace a single, linear gsTFR, over 3.5 orders of magnitude in HI gas+stellar mass. Dwarf ellipticals, however, lie slightly below the gsTFR. This may indicate that early-type dwarfs, contrary to the late-types, have lost their gas, e.g. by galactic winds or ram-pressure stripping. Overall, environment only plays a secondary role in shaping these relations, making them a rather ``clean'' cosmological tool. LCDM simulations predict roughly the correct slopes for these relations.

description: Surfactant transport is central to a diverse range of natural phenomena, and for many practical applications in physics and engineering. Surprisingly, this process remains relatively poorly understood at the molecular scale. This study investigates the mechanism behind the transport of surfactant monolayers on flat and curved liquid vapor interfaces using nonequilibrium molecular dynamics simulations, which are compared with the continuum transport model. This approach not only provides fresh molecular level insight into surfactant dynamics, but also confirms the nanoscale mechanism of the lateral migration of surfactant molecules along a thin film that continuously deforms as surfactants spread. By connecting the continuum model where the long wave approximations prevail, to the molecular details where such approximations break down, we establish that the transport equation preserves substantial accuracy in capturing the underlying physics. Moreover, the relative importance of the different mechanisms of the transport process are identified. Consequently, we derive a novel, exact molecular equation for surfactant transport along a deforming surface. Finally, our findings demonstrate that the spreading of surfactants at the molecular scale adheres to expected scaling laws and aligns well with experimental observations.

Quantumness without quantumness: entanglement as classical correlations in higher dimensions
Creators: name: Vedral, Vlatko
Publisher: name: arXiv
Year: 2007
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: I exploit the formal equivalence between the ground state of a $d$ dimensional quantum system and a d+1 dimensional classical Ising chain to represent quantum entanglement in terms of classical correlations only. This offers a general "local hidden variable model" for all quantum phenomena existing in one dimension lower than the (hidden variable) classical model itself. The local hidden variable model is not contradicted by the implications of Bell's theorem. Formal theory is presented first and then exemplified by the quantum Ising spin chain in a transverse magnetic field. Here I explicitely show how to derive any two site entanglement in the transverse model from the partition function of the classical Ising spin chain existing in two dimensions. Some speculations are then presented regarding possible fundamental implications of these results.

The Experiences of mental health nurses whose clients disclose sexual contact with a former physician : Three comparative case studies
Creators: name: Rae, Margaret I.
Publisher: name: University of British Columbia
Year: 2009

description: This study explored the subjective experiences of community mental health nurses whose clients disclosed sexual contact with a former physician. Theory, opinion literature, and my own clinical experience support the belief that disclosures such as these challenge nurses with their complexity and intensity. Three nurses' accounts of their clients' disclosures constituted cases for comparison and generated a beginning theoretical framework. Data were collected by multiple, indepth, unstructured, audiotaped interviews. Open coding and axial coding techniques of content analysis were used to analyze the data collected, and each set of data was .then compared and contrasted. The Cycle of Focusing Attention was identified as the integrating concept in a conceptual framework that describes how nurses alternately focus their attention on the client and on themselves, with the goal of alleviating client suffering. Contained in this cycle were: two concepts, Focusing on the Client and Focusing on Self; four subconcepts, Collecting Information, Using Interventions, Experiencing Feelings, and Analyzing Thoughts; and two modifying-concepts, Analyzing Boundaries and Analyzing Power. Data analysis revealed that despite the passage of time the details and circumstances of the disclosure experience remained vivid in the nurses' minds. Nurses experienced moral outrage and powerlessness at the physicians' misuse of professional power, and these feelings did not lessen with time. Despite their personal feelings the. nurses maintained a professional demeanor and consistently treated their clients in caring and respectful ways. The nurses were immediately certain that the physician's sexual behavior was unethical. They understood the therapeutic needs of their clients related to client-therapist sexual contact, and the social and ethical demands of reporting. Implementation of the study's findings could lead to more effective clinical practice, thereby lessening the suffering of both client and nurse.

description: We report on the results from a five-night campaign of high-speed spectroscopy of the 17-minute binary AM Canum Venaticorum, obtained with the 4.2-m William Herschel Telescope on La Palma. We derive a mass ratio q=0.18+/-0.01 for AM CVn, which is significantly higher than the value found in previous, less direct measurements. We discuss the implications for AM CVn's evolutionary history and show that a helium star progenitor scenario is strongly favoured. We further discuss the implications for the interpretation of AM CVn's superhump behaviour, and for the detectability of its gravitational-wave signal with LISA. Finally, we test the predictions of an eccentric, precessing disc that are based on AM CVn's observed superhump behaviour. We limit the effective eccentricity in the outermost part of the disc, where the resonances that drive the eccentricity are thought to occur, to e=0.04+/-0.01, which is smaller than previous models indicated.

description: This study presents an experimental investigation of the recently established generalized linear sampling method (GLSM) for non-destructive evaluation of damage in elastic materials. To this end, ultrasonic shear waves are generated in a prismatic slab of charcoal granite featuring a discontinuity interface induced by the three-point bending (3PB). The interaction of probing waves with the 3PB-induced damage gives rise to transient velocity responses measured on the sample's boundary by a 3D scanning laser Doppler vibrometer. Thus obtained waveform data are then carefully processed to retrieve the associated spectra of scattered displacement fields. On deploying multifrequency sensory data, the GLSM indicators are computed and their counterparts associated with the classical linear sampling method (LSM) for comparative analysis. Verified with in-situ observations, the GLSM map successfully exposes the support of hidden scatterers in the specimen with a remarkable clarity and resolution compared to its predecessor LSM. It is further shown that the GLSM remains robust for sparse and partial-aperture data inversion, thanks to its rigorous formulation. For completeness, the one-sided reconstruction by both indicators is investigated.

description: Breaking domain names such as openresearch into component words open and research is important for applications like Text-to-Speech synthesis and web search. We link this problem to the classic problem of Chinese word segmentation and show the effectiveness of a tagging model based on Recurrent Neural Networks (RNNs) using characters as input. To compensate for the lack of training data, we propose a pre-training method on concatenated entity names in a large knowledge database. Pre-training improves the model by 33% and brings the sequence accuracy to 85%.

description: The prompt emission of GRBs has been investigated for more than 50 years but remains poorly understood. Commonly, spectral and temporal profiles of γ-ray emission are analysed. However, they are insufficient for a complete picture on GRB-related physics. The addition of polarization measurements provides invaluable information towards the understanding of these astrophysical sources. In recent years, dedicated polarimeters, such as POLAR and GAP, were built. The former of which observed low levels of polarization as well as a temporal evolution of the polarization angle. It was understood that a larger sample of GRB polarization measurements and time resolved studies are necessary to constrain theoretical models. The POLAR-2 mission aims to address this by increasing the effective area by an order of magnitude compared to POLAR. POLAR-2 is manifested for launch on board the China Space Station in 2024 and will operate for at least 2 years. Insight from POLAR will aid in the improvement of the overall POLAR-2 design. Major improvements (compared to POLAR) will include the replacement of multi-anode PMTs (MAPMTs) with SiPMs, increase in sensitive volume and further technological upgrades. POLAR-2 is projected to measure about 50 GRBs per year with equal or better quality compared to the best seen by POLAR. The instrument design, preliminary results and anticipated scientific potential of this mission will be discussed.

Time Reversal Polarization and a Z_2 Adiabatic Spin Pump

description: We introduce and analyze a class of one dimensional insulating Hamiltonians which, when adiabatically varied in an appropriate closed cycle, define a "$Z_2$ pump". For an isolated system a single closed cycle of the pump changes the expectation value of the spin at each end even when spin orbit interactions violate the conservation of spin. A second cycle, however returns the system to its original state. When coupled to leads, we show that the $Z_2$ pump functions as a spin pump in a sense which we define, and transmits a finite, though non quantized spin in each cycle. We show that the $Z_2$ pump is characterized by a $Z_2$ topological invariant that is analogous to the Chern invariant that characterizes a topological charge pump. The $Z_2$ pump is closely related to the quantum spin Hall effect, which is characterized by a related $Z_2$ invariant. This work presents an alternative formulation which clarifies both the physical and mathematical meaning of that invariant. A crucial role is played by time reversal symmetry, and we introduce the concept of the time reversal polarization, which characterizes time reversal invariant Hamiltonians and signals the presence or absence of Kramers degenerate end states. For non interacting electrons we derive a formula for the time reversal polarization which is analogous to the Berry's phase formulation of the charge polarization. For interacting electrons, we show that abelian bosonization provides a simple formulation of the time reversal polarization. We discuss implications for the quantum spin Hall effect, and argue in particular that the $Z_2$ classification of the quantum spin Hall effect is valid in the presence of electron electron interactions.

description: This paper explains why standardised tariffs for renewable energy generation should continue to play a central role in energy policy. The overall goal is to massively accelerate the uptake of renewables to comply with the Paris Agreement. The demand for new renewable capacity is still not sufficiently incited by the energy markets due to incumbent fossil and nuclear generation and slow electrification of the heat and transport sector. Therefore, policy intervention is still necessary. A New Policy Mix should be envisaged which promotes renewable installations of all system sizes. To that end it is argued that a so-called Surplus Power Tariffs (SPTs) should be introduced for small and medium sized systems. These tariffs would provide a fair remuneration for energy that is not self-consumed or shared. SPT levels would be set just high enough to make minimum viable business case. To achieve a good business case, (joint) self-consumption and energy sharing or further efforts like the provision of systems services will be required. To solve other problems that come with large-scale deployment of renewables, the refinancing mechanisms of the energy system needs to be revisited (levies, taxes, charges, etc.) and a new Energy Market Design is required. The paper builds on the recent study (Jacobs et al. 2020) and aims to provide additional considerations for the design of the New Policy Mix and the underlying tariff schemes.

description: Die zunehmende weltweite Plastikproduktion führt dazu, dass sich in allen Ökosystemen Mikroplastik anreichert, ohne abge-baut zu werden. Während das Recycling von Makroplastik seit Jahrzehnten in der Umweltbildung verankert ist, geraten durch aktuelle Forschung zum Thema Mikroplastik weitere Quellen in den Blick wie Reifenabrieb, Granulat auf Sportplätzen oder synthetische Kleidung. Um Unterrichtskonzepte zu entwickeln, ist es notwendig, die Prädiktoren für Verhalten zu identifizie-ren, das zu weniger Eintrag von (Mikro-)Plastik führt. In diesem Beitrag werden zum einen Ergebnisse zur Vorhersage der Verhaltensintention, weniger Plastik zu verbrauchen und häufiger Bus und Fahrrad zu fahren, präsentiert. Zum anderen werden Evaluationsergebnisse eines Projekttags mit Schüler:innen der Jahrgänge 5 und 6 (N = 349, Gymnasium) berichtet, an dem nach einer Untersuchung von Mikroplastik, seinen Quellen und Folgen für aquatische Ökosysteme das Alltagshandeln reflek-tiert wurde. Basierend auf der Theorie des geplanten Verhaltens konnte gezeigt werden, dass insbesondere die wahrgenommene Verhaltenskontrolle sowie ferner die Einstellungen und subjektive Norm die Verhaltensintention, weniger Plastik zu verbrau-chen und häufiger Bus und Fahrrad zu fahren, vorhersagen. Bzgl. dem Hauptprädiktor, der wahrgenommenen Verhaltenskon-trolle, konnten aus offenen Antworten Herausforderungen konkretisiert werden, die die Schüler:innen einige Wochen nach dem Projekttag retrospektiv berichteten: insbesondere das fehlende plastikfreie Supermarktangebot und Entscheidungen durch Haushaltsmitglieder. Die Evaluation ergab, dass es bei den meisten Prädiktoren und der Verhaltensintention leichte Zuwächse vom Prä- zum Posttest gab, im Follow-Up-Test jedoch ein deutliches Absinken. Auf Grundlage der Ergebnisse werden unter-richtspraktische Implikationen, insbesondere zum Umgang mit der wahrgenommenen Verhaltenskontrolle, diskutiert.

Θέτει ζητήματα που προκύπτουν από τη διεθνή βιβλιογραφία και επιδιώκει να δώσει απαντήσεις στα ακόλουθα ερωτήματα: Πώς προσαρμόστηκαν οι ελληνικές εταιρίες στο ευρωπαϊκό σύστημα εμπορίας ρύπων (EU ETS) και στους μηχανισμούς του Πρωτοκόλλου του Κιότο; Ποιος ο ρόλος του Τμήματος Εσωτερικού Ελέγχου στη διαδικασία λήψης αποφάσεων και στον έλεγχο των συναλλαγών σε δικαιώματα ρύπων; Ποια η συμμετοχή εξωτερικού ελέγχου, κρατικού ή ιδιωτικού, στην καταγραφή και τον έλεγχο των εκπομπών μιας εγκατάστασης; Ποια η περιβαλλοντική πολιτική των εταιριών σε θέματα ρύπων; Η έρευνα πραγματοποιήθηκε με τη μέθοδο του ερωτηματολόγιου, στις ελληνικές εταιρίες που συμμετέχουν στο Εθνικό Σχέδιο Κατανομής Δικαιωμάτων Εκπομπών 2008-2012, με χρονικό πλαίσιο τη 2η φάση του Ευρωπαϊκού Συστήματος Εμπορίας Δικαιωμάτων Εκπομπών (EU ETS), από το 2008 μέχρι σήμερα.
description: The current master thesis explores the Greek CO2 emissions market from the perspective of auditing, internal and external, of companies that emit pollutants and thus participate in the National Allocation Plan (NAP) of the country. It raises issues arising from the literature and seeks to answer the following questions: How have Greek companies adapted to the European Emissions Trading Scheme (EU ETS) and the flexible mechanisms of the Kyoto Protocol? What is the role of the Internal Auditing Department in the decision making and the auditing of the company’s trading in emissions rights? What is the involvement of an external auditor, public or private, in the recording and auditing of the emissions of an installation? What is the environmental policy of the companies on issues regarding emissions? The survey was conducted by means of a questionnaire in Greek companies participating in the National Allocation Plan 2008-2012, during the second phase of the European Emissions Trading Scheme (EU ETS), and in particular, from 2008 until today.

description: We consider the random Erd{\H o}s--Rényi network with enhanced clusterization and Ising spins $s=\pm 1$ at the network nodes. Mutually linked spins interact with energy $J$. Magnetic properties of the system as dependent on the clustering coefficient $C$ are investigated with the Monte Carlo heat bath algorithm. For $J>0$ the Curie temperature $T_c$ increases from 3.9 to 5.5 when $C$ increases from almost zero to 0.18. These results deviate only slightly from the mean field theory. For $J<0$ the spin-glass phase appears below $T_{SG}$; this temperature decreases with $C$, on the contrary to the mean field calculations. The results are interpreted in terms of social systems.

description: We introduce a versatile and spatially resolved morphological characterisation of binary fields, rooted in the opening transform of mathematical morphology. We subsequently apply it to the thresholded ionization field in simulations of cosmic reionization and study the morphology of ionized regions. We find that an ionized volume element typically resides in an ionized region with radius $\sim8\,h^{-1}\mathrm{cMpc}$ at the midpoint of reionization ($z\approx7.5$) and follow the bubble size distribution even beyond the overlap phase. We find that percolation of the fully ionized component sets in when 25% of the universe is ionized and that the resulting infinite cluster incorporates all ionized regions above $\sim8\,h^{-1}\mathrm{cMpc}$. We also quantify the clustering of ionized regions of varying radius with respect to matter and on small scales detect the formation of superbubbles in the overlap phase. On large scales we quantify the bias values of the centres of ionized and neutral regions of different sizes and not only show that the largest ones at the high-point of reionization can reach $b\approx 30$, but also that early small ionized regions are positively correlated with matter and large neutral regions and late small ionized regions are heavily anti-biased with respect to matter, down to $b\lesssim-20$.

description: Σκοπός της διπλωματικής μας διατριβής ήταν να επαληθεύσουμε πως μέσα από τις γραμμές της αντιπαράθεσης για την μεταρρύθμιση του συστήματος κοινωνικής ασφάλισης, καταγράφηκε μια σύγκρουση των εκσυγχρονιστών της κυβέρνησης με τους αντι-εκσυγχρονιστές της εσωκομματικής αντιπολίτευσης του ΠΑΣΟΚ και τους συνδικαλιστές. Αρχικά αναλύσαμε έννοιες κομβικές για την κατανόηση του θέματος μας, όπως το κράτος πρόνοιας, τον φιλελευθερισμό και πως προκύπτουν ο εκσυγχρονισμός και ο αντι-εκσυγχρονισμός και το συνδικαλισμό. Εν συνεχεία, παρουσιάσαμε και αναλύσαμε την επιχειρηματολογία της κυβέρνησης υπέρ του νομοσχεδίου αλλά και του διαλόγου με τα συνδικάτα. Παρουσιάσαμε ακόμα τις αντιδράσεις των οργανωμένων συνδικαλιστών αλλά και την οργανωμένη αντίδραση της εσωκομματικής αντιπολίτευσης του ΠΑΣΟΚ και την τελική τους εναντίωση, μέχρι την ολοκληρωτική απόσυρση του νομοσχεδίου από την κυβέρνηση. Τέλος, αναδείξαμε τα γνωρίσματα του εκσυγχρονιστικού λόγου στις προτάσεις και την επιχειρηματολογία της κυβέρνησης και αυτά του αντι-εκσυγχρονιστικού, αντίστοιχα στην επιχειρηματολογία των συνδικαλιστών και της εσωκομματικής αντιπολίτευσης, πραγματοποιώντας έτσι την επαλήθευση της ερευνητικής μας πρότασης.
description: The purpose of our diplomatic work, was to verify that through the lines of the juxtaposition for the reform of the system of social insurance, was noted a conflict between the modernizers belong to the government and the anti-modernizers of intraparty opposition of PASOK and the trade unionists. At the beginning, we analyzed key concepts for the better understanding of our issue, such as the welfare state, the liberalism and how accrue the modernization and the anti-modernization, and the syndicalism. Continuing, we presented and analyzed the government’s argument for the Bill an the social dialogue with the unions. Moreover, we presented both the reactions of organized trade unionists and intraparty opposition in PASOK and their final opposition and deny, until the complete withdrawal of the Bill by the government. Finally, we highlighted the attributes of modernization dialectic on the proposals and argument of the government and those of anti-modernization dialectic on the argument of trade unionists and the intraparty opposition, thus making the verification of our initial research proposal.

description: We consider W-boson scattering at high-energy e+ e- colliders and study one-loop logarithmic electroweak corrections within the Standard Model assuming a light Higgs boson. We present explicit analytical results for W+ W- -> W+ W-. Using the equivalent vector-boson approximation, we have implemented these corrections into a Monte Carlo program for the process e+ e- -> nue anti-nue W+ W-. The quality of the equivalent vector-boson approximation and of the logarithmic high-energy approximation for the electroweak corrections is discussed in detail. The impact of the radiative effects is quantitatively analysed. The corrections are negative and their size, typically of the order of 10%, increases with energy reaching up to -20% and -50% at the ILC and CLIC, respectively.

Infrared Echoes Reveal the Shock Breakout of the Cas A Supernova

description: (Condensed form) - The serendipitous discovery of infrared echoes around the supernova remnant of Cas A by the Spitzer satellite has provided astronomers with a unique opportunity to study the properties of the echoing material and the history and nature of the outburst that generated these echoes. All the echoes located within a distance of ~15 arcmin from the SN are caused by the delayed arrival of thermal emission from dust located at a distance of 160 lyr (corresponding to half the adopted age of the remnant) directly behind the origin of the explosion. The spectra of the echoes are distinct from that of the general diffuse interstellar medium (ISM) revealing hot silicate grains that are either stochastically heated to temperatures in excess of ~150 K, or radiating at an equilibrium temperature of this value. We show that the optical light curve from the supernova, is not capable of producing such spectra, and could therefore not have given rise to the echoes. Instead, we find that the echoes were generated by an intense and short burst of EUV-UV radiation with a luminosity of ~ 1.5E11 Lsun. The average H-column density of the IR emitting region in the echoing clouds is about 5E17 cm-2. Taking a burst time of ~1 d gives a cloud density of ~200 cm-3, typical of dense IR cirrus.

Griffiths singularities and algebraic order in the exact solution of an Ising model on a fractal modular network

description: We use an exact renormalization-group transformation to study the Ising model on a complex network composed of tightly-knit communities nested hierarchically with the fractal scaling recently discovered in a variety of real-world networks. Varying the ratio K/J of of inter- to intra-community coupling, we obtain an unusual phase diagram: at high temperatures or small K/J we have a disordered phase with a Griffiths singularity in the free energy, due to the presence of rare large clusters, which we analyze through the Yang-Lee zeros in the complex magnetic field plane. As the temperature is lowered, true long-range order is not seen, but there is a transition to algebraic order, where pair correlations have power-law decay with distance, reminiscent of the XY model. The transition is infinite-order at small K/J, and becomes second-order above a threshold value (K/J)_m. The existence of such slowly decaying correlations is unexpected in a fat-tailed scale-free network, where correlations longer than nearest-neighbor are typically suppressed.

The relationship between grammar and cognition
Creators: name: Carter, Ron
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is an attempt to link basic cognitive processes to attested historical developments in the English language, and, in so doing, to arrive at a plausible, natural theory of grammar that accounts for the form of the language at any stage in its history. The main argument is that relational morphemes such as case inflections and prepositions always derive their meaning from concrete object schemas that develop pre-linguistically from our experience with the world in relation to our bodies and our intentional states. Evidence is drawn from linguistic investigations into case that have served as the catalyst for the discussion about how pre-linguistic categorization affects language structure, cognitive (Langacker) and experientialist (Lakoff) orientations to grammatical structure that take the insights of case grammar and reconcile them with research in cognitive psychology (Rosch), and Artificial Intelligence Research (Parallel Distributed Processing) involving the computer modeling of neural functions. The conclusion is that pre-linguistic relational schemas and therefore spatial cognitive function provide a template for grammatical relationships, and, that the computer modeling of neural function supports such a conclusion.
