description: Thermodynamic properties and elementary excitations in $S=1/2$ one-dimensional Heisenberg antiferromagnet KCuGaF$_6$ were investigated by magnetic susceptibility, specific heat and ESR measurements. Due to the Dzyaloshinsky-Moriya interaction with alternating $D$-vectors and/or the staggered $g$-tensor, the staggered magnetic field is induced when subjected to external magnetic field. Specific heat in magnetic field clearly shows the formation of excitation gap, which is attributed to the staggered magnetic field. The specific heat data was analyzed on the basis of the quantum sine-Gordon (SG) model. We observed many ESR modes including one soliton and three breather excitations characteristic of the quantum SG model.

description: We make the first calculation in lattice QCD of two-photon decays of mesons. Working in the charmonium sector, using the LSZ reduction to relate a photon to a sum of hadronic vector eigenstates, we compute form-factors in both the space-like and time-like domains for the transitions $η_c \to γ^* γ^*$ and $χ_{c0} \to γ^* γ^*$. At the on-shell point we find approximate agreement with experimental world-average values.

description: Introduction: The Oral Health Related Quality of Life for Chronic Periodontitis (OHIP-CP) is considered able to assess the impact of periodontitis on quality of life. The aim of the present was to assess its validity and reliability in the Greek population. Materials and Methods: 178 patients completed the questionnaire at university and private dental clinics. Confirmatory and possibly Exploratory Factor analyses of the data were planned to be performed to assess the validity of the tool. Reliability was tested between two successive time points in 25 participants who completed the OHIP-CP twice. Results: The findings of the Confirmatory Factor analysis were unsatisfactory. Exploratory analysis showed that with some modifications, OHIP-CP may retain good psychometric properties. Conclusions: The initial translation of the oral health impact profile for chronic periodontitis tool does not show acceptable validity and reliability. Modifications show that the items of a two-factor and 14-item tool exhibits acceptable psychometric properties for further study in the Greek population.

Η παρούσα μελέτη στοχεύει στη μετάφραση, την πολιτιστική προσαρμογή και χρήση του OHIP-CP στη διεξαγωγή μελέτης επικύρωσης και αξιοπιστίας στον ελληνικό πληθυσμό. Υλικά και μέθοδοι: Συμμετείχαν 178 ασθενείς οι οποίοι ολοκλήρωσαν το ερωτηματολόγιο σε πανεπιστημιακές και ιδιωτικές οδοντιατρικές κλινικές. Επιβεβαιωτικές και διερευνητικές αναλύσεις παραγόντων πραγματοποιήθηκαν για να εκτιμηθεί η εγκυρότητα του εργαλείου. Η αξιοπιστία δοκιμάστηκε μεταξύ δύο διαδοχικών χρονικών μετρήσεων σε 25 συμμετέχοντες που εξετάστηκαν δύο φορές. Αποτελέσματα: Η διερευνητική ανάλυση έδειξε ότι με κάποιες τροποποιήσεις μπορεί να αναδιαμορφωθεί το OHIP-CP σε ένα εργαλείο δύο παραγόντων. Στο εργαλείο 14 στοιχείων που παρήχθη μετά από διερευνητική ανάλυση παραγόντων φάνηκε ότι οι ερωτήσεις εξυπηρετούσαν ικανοποιητικά το σκοπό τους. Συμπεράσματα: Η μετάφραση του OHIP-CP δεν είχε καλές ψυχομετρικές ιδιότητες στον ελληνικό πληθυσμό. Το τροποποιημένο εργαλείο δύο παραγόντων και 14 στοιχείων ίσως φανεί χρήσιμο στο μέλλον μετά από επικύρωση των ιδιοτήτων του σε νέο δείγμα.

Orbital Evolution of Equal-mass Eccentric Binaries due to a Gas Disk: Eccentric Inspirals and Circular Outspirals

description: We solve the equations of two-dimensional hydrodynamics describing a circumbinary disk accreting onto an eccentric, equal-mass binary. We compute the time rate of change of the binary semimajor axis $a$ and eccentricity $e$ over a continuous range of eccentricities spanning $e=0$ to $e=0.9$. We find that binaries with initial eccentricities $e_0 \lesssim 0.1$ tend to $e=0$, where the binary semimajor axis expands. All others are attracted to $e \approx 0.4$, where the binary semimajor axis decays. The $e \approx 0.4$ attractor is caused by a rapid change in the disk response from a nearly origin-symmetric state to a precessing asymmetric state. The state change causes the time rates of change $\dot{a}$ and $\dot{e}$ to steeply change sign at the same critical eccentricity resulting in an attracting solution where $\dot{a} = \dot{e} = 0$. This does not, however, result in a stalled, eccentric binary. The finite-transition time between disk states causes the binary eccentricity to evolve beyond the attracting eccentricity in both directions resulting in oscillating orbital parameters and a drift of the semimajor axis. For the chosen disk parameters, binaries with $e_0 \gtrsim 0.1$ evolve toward and then oscillate around $e \approx 0.4$ where they shrink in semimajor axis. Because unequal mass binaries grow toward equal mass through preferential accretion, our results are applicable to a wide range of initial binary mass ratios. Hence, these findings merit further investigations of this disk transition; understanding its dependence on disk parameters is vital for determining the fate of binaries undergoing orbital evolution with a circumbinary disk.

description: We present a memory-based snowdrift game (MBSG) taking place on networks. We found that, when a lattice is taken to be the underlying structure, the transition of spatial patterns at some critical values of the payoff parameter is observable for both 4 and 8-neighbor lattices. The transition points as well as the styles of spatial patterns can be explained by local stability analysis. In sharp contrast to previously reported results, cooperation is promoted by the spatial structure in the MBSG. Interestingly, we found that the frequency of cooperation of the MBSG on a scale-free network peaks at a specific value of the payoff parameter. This phenomenon indicates that properly encouraging selfish behaviors can optimally enhance the cooperation. The memory effects of individuals are discussed in detail and some non-monotonous phenomena are observed on both lattices and scale-free networks. Our work may shed some new light on the study of evolutionary games over networks.

description: The development of EDI technology has created many concerns and challenges for the auditing profession. Along with its many suggested benefits, the technology brings an important potential to change business information systems and the way businesses operate. As a consequence, it may put auditors in a new audit environment and may thus force significant modification to the established methods of auditing. This study identifies important EDI audit issues as viewed by information systems auditors in the greater Vancouver area. A three round Delphi methodology was used to solicit opinions from a group of IS audit experts. The expert respondents predominantly held managerial positions in internal audit functions while their organizations comprised a wide cross section of sizes and industries. The research findings reveal a consensus set of eleven most important issues. Among these EDI audit issues, "Controls Over EDI Network", "Backup, Disaster Recovery and Contingency Plans", "Auditability and Audit Trail", "Audit Involvement during the System Development", and "Legal and Audit Evidence" are rated in the top five ranks.

Effects of correlated variability on information entropies in nonextensive systems

description: We have calculated the Tsallis entropy and Fisher information matrix (entropy) of spatially-correlated nonextensive systems, by using an analytic non-Gaussian distribution obtained by the maximum entropy method. Effects of the correlated variability on the Fisher information matrix are shown to be different from those on the Tsallis entropy. The Fisher information is increased (decreased) by a positive (negative) correlation, whereas the Tsallis entropy is decreased with increasing an absolute magnitude of the correlation independently of its sign. This fact arises from the difference in their characteristics. It implies from the Cramér-Rao inequality that the accuracy of unbiased estimate of fluctuation is improved by the negative correlation. A critical comparison is made between the present study and previous ones employing the Gaussian approximation for the correlated variability due to multiplicative noise.

Vorlesestunden, Bilderbuchkinos und Autorenlesungen sind vielerorts Teil des Standardprogramms. Seit einiger Zeit wird auch die Vermittlung von Informationskompetenz, insbesondere was das Internet betrifft, immer weiter in die Veranstaltungskalender integriert. Diese Angebote werden sicherlich auch in Zukunft Bestand haben, es stellt sich jedoch die Frage, wie sie sich im Umfeld der Digitalisierung der Gesellschaft weiterentwickeln werden. Ein Ansatz kann hier sein, zukünftig auch die Scientific Literacy zu berücksichtigen. Wir bewegen uns in einer zunehmend technisierten Gesellschaft, die jedoch dringend mehr Fachkräfte benötigt. Während auf der einen Seite Impfgegner und Leugner des Klimawandels Auftrieb erhalten, werden auf der anderen Seite jedwede wissenschaftliche Studien kritiklos übernommen und verallgemeinert. Ein solides Grundwissen zu wissenschaftlichen Methoden, zu deren Vorteilen und Grenzen, wird also auch in Zukunft von großer Bedeutung sein. Im folgenden Beitrag soll ein Ansatz diskutiert werden, der praxisnah zur Vermittlung dieser Kompetenzen genutzt werden kann: Citizen Science, auf Deutsch auch Bürgerwissenschaft genannt, also die Durchführung wissenschaftlicher Forschung unter Beteiligung Freiwilliger.
Manganese(I)-catalyzed (asymmetric) reduction of carbonyl bonds

Subjects: subject: 540 Chemistry & allied sciences

description: This dissertation reports the synthesis of different non-noble metal complexes for the (asymmetric) reduction of predominantly ketones or esters to the corresponding alcohols. Thereby, mainly pincer ligands coordinated to a manganese(I) metal center were used while corresponding noble metal analogues already have demonstrated good activities in different reductions of organic compounds. Manganese(I) was used as a metal center because of its high abundance, low price and only minor toxicity in comparison to other noble metals.

In this paper we present methods and an algorithm that, by means of extensive computer simulation--based experimental campaigns (ISTC) guided by intelligent search, optimise a pharmacological treatment for an individual patient (precision medicine). e show the effectiveness of our approach on a case study involving a real pharmacological treatment, namely the downregulation phase of a complex clinical protocol for assisted reproduction in humans.

description: The SFI++ consists of ~5000 spiral galaxies which have measurements suitable for the application of the I-band Tully-Fisher (TF) relation. This sample builds on the SCI and SFI samples published in the 1990s but includes significant amounts of new data as well as improved methods for parameter determination. We derive a new I-band TF relation from a subset of this sample which consists of 807 galaxies in the fields of 31 nearby clusters and groups. This sample constitutes the largest ever available for the calibration of the TF template and extends the range of line-widths over which the template is reliably measured. Careful accounting is made of observational and sample biases such as incompleteness, finite cluster size, galaxy morphology and environment. We find evidence for a type-dependent TF slope which is shallower for early type than for late type spirals. The line-of-sight cluster peculiar velocity dispersion is measured for the sample of 31 clusters. This value is directly related to the spectrum of initial density fluctuations and thus provides an independent verification of the best fit WMAP cosmology and an estimate of Omega^0.6 sigma_8 = 0.52+/-0.06. We also provide an independent measure of the TF zeropoint using 17 galaxies in the SFI++ sample for which Cepheid distances are available. In combination with the ``basket of clusters'' template relation these calibrator galaxies provide a measure of H0 = 74+/-2 (random) +/-6 (systematic) km/s/Mpc.

description: Βασικός στόχος της παρούσας εργασίας είναι η ανάδειξη της υποτίμηση ενός νομίσματος ως εργαλείο οικονομικής πολιτικής. Υπό αυτό το πρίσμα, πραγματοποιείται εκτενής βιβλιογραφική επισκόπηση, ώστε να παρουσιαστούν κυρίαρχες προσεγγίσεις και υποδείγματα που εξετάζουν τα αποτελέσματα μιας νομισματικής υποτίμησης. Εν συνεχεία, βάσει της πρότερης ανάλυσης, παρατίθενται οι δίαυλοι μέσω των οποίων διαχέονται οι επιδράσεις της υποτίμησης στην οικονομία. Παράλληλα, σημείο ενδιαφέροντος στην παρούσα εργασία, αποτελεί η πρόβλεψη των πραγματικών μακροχρόνιων συναλλαγματικών ισοτιμιών. Έτσι παρουσιάζεται η βασική κριτική που έχει ασκηθεί στα συμβατικά μοντέλα πρόβλεψης, καθώς και η κλασική προσέγγιση, ως αντιπρόταση, όπως διατυπώθηκε από τον Α. Shaikh. Το μεγαλύτερο τμήμα της εργασίας όμως, εστιάζει στη μελέτη της ελληνικής οικονομίας. Η μελέτη της περίπτωσης της Ελλάδας εναρμονίζεται πλήρως με το βασικό ερευνητικό ερώτημα. Ξεφεύγοντας από μια στείρα γεγονοτολογική και αποσπασματική αφήγηση, ανατέμνεται η οικονομική ιστορία της περιόδου 1944-1989, δίνοντας ιδιαίτερη έμφαση στις πραγματοποιηθείσες υποτιμήσεις. Συγχρόνως, φωτίζεται το πως η ελληνική οικονομία ανταποκρινόταν στο διεθνή ανταγωνισμό, τόσο εντός ενός καθεστώτος σταθερών συναλλαγματικών ισοτιμιών, όπως το Bretton Woods, όσο και υπό καθεστώς ελεύθερα κυμαινόμενων συναλλαγματικών ισοτιμιών.
description: The main purpose of the present work is to show how the devaluation of a currency can be used as an economic policy tool. Under this light, an extended literature review is carried out, in order to present the dominant approaches and models that examine the results of a currency devaluation. Afterwards, according to the prior analysis, the channels by which the effects of a devaluation spread on the economy are exposed. At the same time, another point of interest in this research is the forecast of the real long-run exchange rates. As a result, the dominant critique on the conventional forecasting models is presented, along with the alternative theory of exchange rates, as proposed by A. Shaikh. However, the largest part of the thesis focuses on the study of the Greek economy. The examination of the Greek case is aligned completely to the fundamental question posed by the thesis. Escaping a fragmented and abridged narration, the economic history of the 1944-1989 period is thoroughly examined, emphasizing on the applied devaluations. Simultaneously, the responses of the Greek economy to the international competition, both in the regimes of constant exchange rates, including the Bretton Woods system, and in the floating exchange rates regimes, are illuminated.

description: We investigate here the Cooper pairing of fermionic atoms with mismatched fermi surfaces using a variational construct for the ground state. We determine the state for different values of the mismatch of chemical potential for weak as well as strong coupling regimes including the BCS BEC cross over region. We consider Cooper pairing with both zero and finite net momentum. Within the variational approximation for the ground state and comparing the thermodynamic potentials, we show that (i) the LOFF phase is stable in the weak coupling regime, (ii) the LOFF window is maximum on the BEC side near the Feshbach resonance and (iii) the existence of stable gapless states with a single fermi surface for negative average chemical potential on the BEC side of the Feshbach resonance.

description: Η παρούσα διπλωματική εργασία μελετά την αναπαράσταση του κήπου σε δύο αγγλικά και ιταλικά μυθιστορήματα του 19ου αιώνα με εργαλείο τη θεωρία της οικοκριτικής. Η οικοκριτική συνδέεται στενά με την επιστήμη της οικολογίας και μελετά τη λογοτεχνία και το περιβάλλον μέσα από μία διεπιστημονική προσέγγιση. Τα δύο αγγλικά μυθιστορήματα που επέλεξα είναι το Great Expectations (Μεγάλες Προσδοκίες, 1861) του Charles Dickens και το Jane Eyre (Τζέιν Έιρ, 1847) της Charlotte Brontë στα οποία ο κήπος έχει σημαντική θέση και η αναπαράσταση του έχει οικολογικές προεκτάσεις. Τα έργα της ιταλικής λογοτεχνίας είναι το Malombra (Μαλόμπρα, 1881) και το Piccolo Mondo Antico (Μικρός παλαιός κόσμος, 1895) του ίδιου συγγραφέα, του Antonio Fogazzaro, καθώς στην ιταλική λογοτεχνία δεν υπάρχει τόσο πλούσιο υλικό όπως στην αγγλική λογοτεχνία (ειδικά σε συνδυασμό με την οικολογία). Η ανάλυση της εικόνας του κήπου μέσα στα έργα απαντάει σε ερωτήματα που αφορούν τη σχέση του ανθρώπου με τη φύση και την κοινωνία τη συγκεκριμένη εποχή και φέρνει στην επιφάνεια μια νέα, οικολογική πτυχή των έργων. Τέλος, μέσα από τη σύγκριση των μυθιστορημάτων εντοπίζονται τα κοινά στοιχεία και οι διαφορές ανάμεσα στην αγγλική και ιταλική λογοτεχνική παραγωγή της περιόδου.
description: This thesis studies the representation of the garden in two English and Italian novels of the 19th century using ecocriticism as a tool. Ecocriticism is closely related to ecology and studies literature and the environment through an interdisciplinary approach. The two English novels I chose are, Charles Dickens’s Great Expectations (1861) and Charlottes Brontë’s Jane Eyre (1847) in which the representation of the garden has ecological connotations. The Italian novels are Malombra (1881) and Piccolo Mondo Antico (1895) both of the same writer, Antonio Fogazzaro, due to the fact that there are not so many Italian literary works related to ecology as in English literature. The analysis of the representation of the garden answers questions regarding the relationship of man, nature and society in that particular era and brings to surface a new, ecological aspect of the novels. Last but not least, through the comparison of the novels the similarities and differences between the English and Italian literature of that era are brought to light.

description: In critical infrastructures like airports, much care has to be devoted in protecting radio communication networks from external electromagnetic interference. Protection of such mission-critical radio communication networks is usually tackled by exploiting radiogoniometers: at least three suitably deployed radiogoniometers, and a gateway gathering information from them, permit to monitor and localise sources of electromagnetic emissions that are not supposed to be present in the monitored area. Typically, radiogoniometers are connected to the gateway through relay nodes. As a result, some degree of fault-tolerance for the network of relay nodes is essential in order to offer a reliable monitoring. On the other hand, deployment of relay nodes is typically quite expensive. As a result, we have two conflicting requirements: minimise costs while guaranteeing a given fault-tolerance. In this paper, we address the problem of computing a deployment for relay nodes that minimises the relay node network cost while at the same time guaranteeing proper working of the network even when some of the relay nodes (up to a given maximum number) become faulty (fault-tolerance). We show that, by means of a computation-intensive pre-processing on a HPC infrastructure, the above optimisation problem can be encoded as a 0/1 Linear Program, becoming suitable to be approached with standard Artificial Intelligence reasoners like MILP, PB-SAT, and SMT/OMT solvers. Our problem formulation enables us to present experimental results comparing the performance of these three solving technologies on a real case study of a relay node network deployment in areas of the Leonardo da Vinci Airport in Rome, Italy.

description: This paper has four main parts. In the first part, we construct a noncommutative residue for the hypoelliptic calculus on Heisenberg manifolds, that is, for the class of Heisenberg PsiDOs introduced by Beals-Greiner and Taylor. This noncommutative residue appears as the residual trace on integer order Heisenberg PsiDOs induced by the analytic extension of the usual trace to non-integer order Heisenberg PsiDOs. Moreover, it agrees with the integral of the density defined by the logarithmic singularity of the Schwartz kernel of the corresponding Heisenberg PsiDO. In addition, we show that this noncommutative residue provides us with the unique trace up to constant multiple on the algebra of integer order Heisenberg PsiDOs. In the second part, we give some analytic applications of this construction concerning zeta functions of hypoelliptic operators, logarithmic metric estimates for Green kernels of hypoelliptic operators, and the extension of the Dixmier trace to the whole algebra of integer order Heisenberg PsiDOs. In the third part, we present examples of computations of noncommutative residues of some powers of the horizontal sublaplacian and the contact Laplacian on contact manifolds. In the fourth part, we present two applications in CR geometry. First, we give some examples of geometric computations of noncommutative residues of some powers of the horizontal sublaplacian and of the Kohn Laplacian. Second, we make use of the framework of noncommutative geometry and of our noncommutative residue to define lower dimensional volumes in pseudohermitian geometry, e.g., we can give sense to the area of any 3-dimensional CR manifold. On the way we obtain a spectral interpretation of the Einstein-Hilbert action in pseudohermitian geometry.

description: Η παρούσα διπλωματική εργασία παρουσιάζει, αναπτύσσει και σχολιάσει τα εκπαιδευτικά νομοσχέδια του 1899, τα οποία αναφέρονται σε όλες τις εκπαιδευτικές βαθμίδες που εισήγαγε ο τότε Υπουργός Εκκλησιαστικών και Δημοσίας Εκπαιδεύσεως, Αθανάσιος Ευταξίας. Σκοπός είναι η ανάδειξη και κατάδειξη της σημασίας αυτών των εκπαιδευτικών νομοσχεδίων κατά την περίοδο εκείνη μέσω της παρουσίασης των ιστορικών, πολιτικών, οικονομικών και εκπαιδευτικών συνθηκών. Στο κυρίως μέρος της εργασίας αναλύεται το περιεχόμενό τους και οι συζητήσεις που ακολούθησαν την εισήγησή τους στη Βουλή, ενώ δεν θα μπορούσε να παραλειφθεί η βιογραφία του Ευταξία, έργα σχετικά με την εκπαίδευση του ιδίου αλλά και η παραίτησή του, η οποία ήταν αποτέλεσμα έντονων αντιπαραθέσεων. Η εργασία κλείνει με συμπεράσματα και σχόλια τόσο πάνω στα ίδια τα νομοσχέδια, το εκπαιδευτικό σύστημα της εποχής και της ανάγκης που έχρηζε για εκπαιδευτικές μεταρρυθμίσεις, αλλά και του τρόπου με τον οποίο αυτά τα νομοσχέδια συνδέονταν με τις εξελίξεις που διαδραματίζονταν εκείνη την περίοδο στην ελληνική κοινωνία.
description: This diploma thesis presents, develops and comments on the educational bills of 1899, which refers to all educational levels, introduced by the ex Minister of Ecclesiastical and Public Education, Athanasios Eftaxias. The aim is to highlight and demonstrate the importance of these educational drafts at that time through the presentation of the historical, political, economic and educational conditions. The main part of the paper analyzes their content and the discussions that followed their presentation to the Greek Parliament, while the biography of Eftaxias could not be omitted, works of his own on education and his resignation, which was the result of intense confrontations. The project concludes with conclusions and comments on both the bills themselves, the educational system of the era and the need for educational reforms, but also the way in which these bills were linked to the developments that were taking place at that time in the Greek society.
Renormalized holographic entanglement entropy in Lovelock gravity

description: We study the renormalization of Entanglement Entropy in holographic CFTs dual to Lovelock gravity. It is known that the holographic EE in Lovelock gravity is given by the Jacobson-Myers (JM) functional. As usual, due to the divergent Weyl factor in the Fefferman-Graham expansion of the boundary metric for Asymptotically AdS spaces, this entropy functional is infinite. By considering the Kounterterm renormalization procedure, which utilizes extrinsic boundary counterterms in order to renormalize the on-shell Lovelock gravity action for AAdS spacetimes, we propose a new renormalization prescription for the Jacobson-Myers functional. We then explicitly show the cancellation of divergences in the EE up to next-to-leading order in the holographic radial coordinate, for the case of spherical entangling surfaces. Using this new renormalization prescription, we directly find the $C-$function candidates for odd and even dimensional CFTs dual to Lovelock gravity. Our results illustrate the notable improvement that the Kounterterm method affords over other approaches, as it is non-perturbative and does not require that the Lovelock theory has limiting Einstein behavior.

description: We investigate the properties of baryonic matter within the framework of the in-medium modified chiral soliton model by taking into account the effects of surrounding baryonic environment on the properties of in-medium baryons. The internal parameters of the model are determined based on nuclear phenomenology at nonstrange sector and fitted by reproducing nuclear matter properties near the saturation point. We discuss the equations of state in different nuclear environments such as symmetric nuclear matter, neutron and strange matters. We show that the results for the equations of state are in good agreement with the phenomenology of nuclear matter. We also discuss how the SU(3) baryons masses undergo changes in these various types of nuclear matter.

description: Τα Αναλυτικά Προγράμματα Σπουδών αποτελούν τη βάση του εκπαιδευτικού συστήματος. Οι τεχνολογίες -λόγω της ραγδαίας εξέλιξής τους- είναι από τις ενδιαφέρουσες περιοχές προς συζήτηση και επαναπροσδιορισμό μέσα στα αναλυτικά προγράμματα όλων των χωρών. Για αυτό και παρατηρείται τακτικά η αναθεώρησή τους. Ο σκοπός της παρούσας εργασίας ήταν να μελετήσει την ένταξη των ΤΠΕ στα Αναλυτικά Προγράμματα Ελλάδας και Αυστραλίας. Πιο συγκεκριμένα, μέσα από τη σύγκρισή τους έγινε προσπάθεια να επισημανθούν οι ομοιότητες, αλλά και οι διαφορές τους σε ένα σύστημα κατηγοριών που αποτελούν στοιχεία της δομής τους και της ανάπτυξής τους. Η σύγκριση έδειξε ότι υπάρχουν ομοιότητες που όμως εντοπίζονται κυρίως στις γενικές προθέσεις των δύο αναλυτικών προγραμμάτων. Περισσότερες είναι οι διαφορές που αφορούν στα βασικά σημεία των Αναλυτικών Προγραμμάτων όπως οι στόχοι, το περιεχόμενο και η κεντρική ιδέα γύρω από την οποία αναπτύσσονται. Τα δύο κράτη φαίνεται πως απέχουν μεταξύ τους όχι μόνο ως προς την απόσταση αλλά και στα βήματα που έχουν κάνει σε σχέση με την ενσωμάτωσή τους στο εκπαιδευτικό τους πρόγραμμα.
description: School curricula form the basis of the education system. Due to their rapid development technologies are considered as an interesting subject for discussion and redefinition in the curricula of all countries. This is why they are being reviewed regularly. The purpose of this paper was to study the integration of ICT in Greece and Australia primary education. More specifically, the comparison of the two countries attempted to highlight their similarities but also the differences in a system of categories that are elements of their structure and development. The comparison revealed that similarities do exist but they are mainly focused on the general intentions of both curricula. There are more differences regarding the core points of the school curriculum as the goals, content and central idea around which they are developing. The two countries seem to be, not just literally far away from each other but also in the progress they have made regarding the integration of ICT in their educational program.

description: We derive an integral convex combination of product states for a range of separable Werner states. Our method consists of expanding the sought-after local density operators in terms of Wigner operators. For dimension d=2, our decomposition holds for the whole separable range of Werner states, while for d>2 it is valid for a subset of separable Werner states. We illustrate the general method with the explicit examples d=2 and d=3.

description: Using the recently introduced boundary form factor bootstrap equations, we map the complete space of their solutions for the boundary version of the scaling Lee-Yang model and sinh-Gordon theory. We show that the complete space of solutions, graded by the ultraviolet behaviour of the form factors can be brought into correspondence with the spectrum of local boundary operators expected from boundary conformal field theory, which is a major evidence for the correctness of the boundary form factor bootstrap framework.

Non-volatile resistive switching in dielectric superconductor YBCO

description: We report on the reversible, nonvolatile and polarity dependent resistive switching between superconductor and insulator states at the interfaces of a Au/YBa$_2$Cu$_3$O$_{7-δ}$ (YBCO)/Au system. We show that the superconducting state of YBCO in regions near the electrodes can be reversibly removed and restored. The possible origin of the switching effect may be the migration of oxygen or metallic ions along the grain boundaries that control the intergrain superconducting coupling. Four-wire bulk resistance measurements reveal that the migration is not restricted to interfaces and produce significant bulk effects.

Alcock-Paczynski effects on wide-angle galaxy statistics

description: The Alcock-Paczynski (AP) effect is a geometrical distortion in three-dimensional observed galaxy statistics. In anticipation of precision cosmology based on ongoing and upcoming all-sky galaxy surveys, we build an efficient method to compute the AP-distorted correlations of galaxy number density and peculiar velocity fields for any larger angular scale not relying on the conventionally used plane-parallel (PP) approximation. Here, instead of the usual Legendre polynomial basis, the correlation functions are decomposed using tripolar spherical harmonic basis; hence, characteristic angular dependence due to the wide-angle AP effect can be rigorously captured. By means of this, we demonstrate the computation of the AP-distorted correlations over the various scales. Comparing our results with the PP-limit ones, we confirm that the errors due to the PP approximation become more remarkable as the visual angle of separation between target galaxies, $Θ$, enlarges, and especially for the density auto correlation, the error exceeds $10\%$ when $Θ\gtrsim 30^\circ$. This highlights the importance of the analysis beyond the PP approximation.

The experience of aging : a qualitative study of well elderly individuals
Creators: name: Tomilson, Roxanne Gaye
Publisher: name: University of British Columbia
Year: 2008

description: This phenomenological study was designed to explore and describe the perceptions of well elders who are experiencing aging. The study was conducted with a sample of nine elders ranging in age from 65 to 77 years. Data were collected by intensive interviewing usually at the community centre or at the home of the elder. The data were analyzed for common themes. The findings revealed that the elderly participants described their aging experience in terms of control. The concept of control was mentioned in relation to lifestyle, finances, and health. The participants repeatedly emphasized that their degree of control directly related to how positively they viewed the aging experience. In other words, the greater the elder's perceived control over lifestyle, finances, and health, the greater the elder's positive perception of aging. The results of a study such as this can be used to facilitate the individual nurse's development of knowledge and expertise as it provides information that may be used in developing and providing nursing services for the elderly population.
