description: We show that the generation of entanglement of two heavily macroscopic mirrors with masses of up to several kilograms are feasible with state of the art techniques of high-precision laser interferometry. The basis of such a demonstration would be a Michelson interferometer with suspended mirrors and simultaneous homodyne detections at both interferometer output ports. We present the connection between the generation of entanglement and the Standard Quantum Limit (SQL) for a free mass. The SQL is a well-known reference limit in operating interferometers for gravitational-wave detection and provides a measure of when macroscopic entanglement can be observed in the presence of realistic decoherence processes.

description: We study cosmologies based on low-energy effective string theory with higher-order string corrections to a tree-level action and with a modulus scalar field (dilaton or compactification modulus). In the presence of such corrections it is possible to construct nonsingular cosmological solutions in the context of Pre-Big-Bang and Ekpyrotic universes. We review the construction of nonsingular bouncing solutions and resulting density perturbations in Pre-Big-Bang and Ekpyrotic models. We also discuss the effect of higher-order string corrections on dark energy universe and show several interesting possibilities of the avoidance of future singularities.

Adam von Fulda on musica plana and compositio : De musica, book II : a translation and commentary
Creators: name: Slemon, Peter John
Publisher: name: University of British Columbia
Year: 2009

description: Adam von Fulda, German musician, composer and teacher, completed his important treatise on music in 1490. While representing a conservative, northern tradition in late-medieval music theory, it also shows some evidence of humanist influence. The treatise is divided into four books which discuss the origins and uses of music, the theory of plainchant, mensuration and notation of rhythm, and proportions, respectively. Thus, throughout this informative work, Adam mixes the practical with the speculative. Although his style of explaining technical matters is clear and succinct, he also engages the reader's interest with his polemical and rhetorical digressions. This dissertation presents a detailed commentary upon Book II of the treatise, on musica plana (plainchant), accompanied by a translation from the Latin. The first two chapters of the dissertation are concerned with the biographical information available on Adam von Fulda, as well as with the format and transmission of the treatise. Three chapters of the dissertation serve as the commentary. Chapter III discusses Adam's treatment of the practical aspects of singing plainchant, including his discussions of the Guidonian hand, the gamut, the naming of pitches, hexachords and mutation (material covered in Chapters 1 to 6 of the treatise's second book). Chapter IV of the dissertation considers the subject of musical intervals as covered by Adam, and the ten rules of composition provided in his Chapters 7 to 12. These rules are perhaps the most interesting and unusual part of Book II, as they go beyond the stated subject of plainchant. Written composition, not just improvised counterpoint, is treated in a manner that anticipates later humanist regard for music as an art. Finally, Chapter V examines Adam's treatment of the modes of plainchant (discussed in his Chapters 13 to 17). A conclusion summarizes Adam's impact on later theorists and the importance of the treatise.
Edge Currents for Quantum Hall Systems, II. Two-Edge, Bounded and Unbounded Geometries

description: Devices exhibiting the integer quantum Hall effect can be modeled by one-electron Schroedinger operators describing the planar motion of an electron in a perpendicular, constant magnetic field, and under the influence of an electrostatic potential. The electron motion is confined to bounded or unbounded subsets of the plane by confining potential barriers. The edges of the confining potential barriers create edge currents. This is the second of two papers in which we review recent progress and prove explicit lower bounds on the edge currents associated with one- and two-edge geometries. In this paper, we study various unbounded and bounded, two-edge geometries with soft and hard confining potentials. These two-edge geometries describe the electron confined to unbounded regions in the plane, such as a strip, or to bounded regions, such as a finite length cylinder. We prove that the edge currents are stable under various perturbations, provided they are suitably small relative to the magnetic field strength, including perturbations by random potentials. The existence of, and the estimates on, the edge currents are independent of the spectral type of the operator.

description: We present a comprehensive analysis of 2-charge fuzzball solutions, that is, horizon-free non-singular solutions of IIB supergravity characterized by a curve on R^4. We propose a precise map that relates any given curve to a specific superposition of R ground states of the D1-D5 system. To test this proposal we compute the holographic 1-point functions associated with these solutions, namely the conserved charges and the vacuum expectation values of chiral primary operators of the boundary theory, and find perfect agreement within the approximations used. In particular, all kinematical constraints are satisfied and the proposal is compatible with dynamical constraints although detailed quantitative tests would require going beyond the leading supergravity approximation. We also discuss which geometries may be dual to a given R ground state. We present the general asymptotic form that such solutions must have and present exact solutions which have such asymptotics and therefore pass all kinematical constraints. Dynamical constraints would again require going beyond the leading supergravity approximation.

description: Embedded principalization of ideals in smooth schemes, also known as Log-resolutions of ideals, play a central role in algebraic geometry. If two sheaves of ideals, say $I_1$ and $I_2$, over a smooth scheme $V$ have the same integral closure, it is well known that Log-resolution of one of them induces a Log-resolution of the other. On the other hand, in case $V$ is smooth over a field of characteristic zero, an algorithm of desingularization provides, for each sheaf of ideals, a unique Log-resolution. In this paper we show that algorithms of desingularization define the same Log-resolution for two ideals having the same integral closure. We prove this result here by using the form of induction introduced by Włodarczyk. We extend the notion of Log-resolution of ideals over a smooth scheme $V$, to that of Rees algebras over $V$; and then we show that two Rees algebras with the same integral closure undergo the same constructive resolution. The key point is the interplay of integral closure with differential operators.

description: Solar oscillations consist of a rich spectrum of internal acoustic waves and surface gravity waves, stochastically excited by turbulent convection. They have been monitored almost continuously over the last ten years with high-precision Doppler images of the solar surface. The purpose of helioseismology is to retrieve information about the structure and the dynamics of the solar interior from the frequencies, phases, and amplitudes of solar waves. Methods of analysis are being developed to make three-dimensional images of subsurface motions and temperature inhomogeneities in order to study convective structures and regions of magnetic activity, like sunspots.

description: Using a 2D Viscoresistive Reduced MagnetoHydroDynamic (VR-RMHD) model, the magnetic island coalescence problem is studied in the presence of in-plane, parallel shear flows. Extending the analytical work of Waelbroeck et al [33] and Throumoulopoulos et al [34] in the sub-Alfvénic flow shear regime for Fadeev equilibrium, the super-Alfvénic regime is studied for the first time numerically. A wide range of values of shear flow amplitudes and shear scale lengths have been considered to understand the effect of sub-Alfvénic and super-Alfvénic flows on the coalescence instability and its nonlinear fate. We find that for flow shear length scales greater than the magnetic island size, the maximum reconnection rate decreases monotonically from sub-Alfvénic to super- Alfvénic flow speeds. For scale lengths smaller than the island size, the reconnection rate decreases upto a critical value $v_{0c}$, beyond which, the shear flow is found to destabilize the islands. The value of v0c decreases with decrease in the value of shear flow length scale. Interestingly, for our range of parameters, we find suppression of the Kelvin-Helmholtz instability in super-Alfvénic flows even when the shear scale length is smaller than the island width. Observation of velocity streamlines shows that the plasma circulation inside the islands has a stabilizing influence in strong shear flow cases. Plasma circulation is also found to be responsible for decrease in upstream velocity, causing less pile-up of magnetic flux on both sides of the reconnection sheet.

description: Various galactic globular clusters display abundance anomalies that affect the morphology of their colour-magnitude diagrams. In this paper we consider the possibility of helium enhancement in the anomalous horizontal branch of NGC 2808. We examine the dynamics of a self-enrichment scenario in which an initial generation of stars with a top-heavy initial mass function enriches the interstellar medium with helium via the low-velocity ejecta of its asymptotic giant branch stars. This enriched medium then produces a second generation of stars which are themselves helium-enriched. We use a direct N-body approach to perform five simulations and conclude that such two-generation clusters are both possible and would not differ significantly from their single-generation counterparts on the basis of dynamics. We find, however, that the stellar populations of such clusters would differ from single-generation clusters with a standard initial mass function and in particular would be enhanced in white dwarf stars. We conclude, at least from the standpoint of dynamics, that two-generation globular clusters are feasible.

Interaction of complement with human cytomegalovirus
Creators: name: Spiler, Owen Bradley
Publisher: name: University of British Columbia
Year: 2009

description: In the absence of specific anti-human cytomegalovirus (HCMV) antibodies, complement has a negligible neutralizing effect on the virions. Under these conditions, the presence of activated C3 fragments, but not C9, were found on the HCMV virions. There are no known viral complement inhibitors encoded in the HCMV genome, but the presence of host-encoded complement inhibitors, CD55, CD46, and CD59, on the HCMV virions may explain the virion’s ability to regulate complement. In the presence of anti-HCMV antibodies, complement enhanced the neutralizing ability of the immunoglobulins by 2-3 fold. Complement activation in the presence of antibodies occurred primarily by the classical complement activation pathway and was complete, as assessed by the presence of C9. CD55 (decay-accelerating factor) and CD46 (membrane co-factor protein) regulate complement at the level of C3 and belong the regulators of complement activation (RCA) gene cluster. CD59 regulates complement at the level of the terminal lytic pathway and does not belong to the RCA gene cluster. HCMV infection of fibroblasts and glioblastoma cells resulted in a 3-8 fold increase in the expression of CD55 and CD46 by 72 h p.i., but infection with herpes simplex virus or adenovirus had no effect. An increase in C3 convertase regulation was also found on the HCMV-infected cells using a purified complement component assay. By contrast, CD59 expression was decreased on HCMV-infected cells by 50% by 72 h p.i., similar to the decrease observed for HLA class I. CD55 expression was increased in HCMV-infected cells at the level of protein, mRNA, and transcription of the gene as assessed by using a variety of techniques. Similarly, the levels of CD59 mRNA decreased in the HCMV infected cells, paralleling the observations for protein expression, but radiolabel pulse-chase analysis identified a decreased CD59 protein survival. Indirect evidence suggested that the immediate early or early genes from HCMV were responsible for the altered expression of host complement inhibitors, but CD55 promoter activity and protein expression were unaffected by the presence of isolated HCMV immediate early genes.

description: We present a theoretical scheme based on su(2) algebra to investigate the influence of homogeneous gravitational field on the quantum nondemolition measurement of atomic momentum in dispersive Jaynes-Cummings model. In the dispersive Jaynes-Cummings model, when detuning is large and the atomic motion is in a propagating light wave, we consider a two-level atom with quantized cavity-field in the presence of a homogeneous gravitational field. We derive an effective Hamiltonian describing the dispersive atom-field interaction in the presence of gravitational field. We can see gravitational influence both on the momentum filter and momentum distribution. Moreover, gravitational field decreases both tooth spacing of momentum and the width of teeth of momentum.

description: We calculate DIS-scheme splitting and coefficient functions for electromagnetic deep inelastic scattering with small x resummations, as given by the NLL BFKL equation with running coupling and approximate NLL resummed impact factors. The resummations are combined with a NLO fixed order expansion, and the improved quantities thus obtained are stable at small x and significantly suppressed with respect to LL results. These results are implemented in a global fit to DIS and related data, and the results compared to a NLO fixed order DIS-scheme fit and with a previous LL resummed fit. The NLL resummed fit quality is excellent, and constitutes a marked improvement over the purely fixed order approach. The input gluon, at Q_0^2=1GeV^2, obtained from the resummed fit is positive and slightly increasing as x-->0, in contrast to the result obtained at fixed order. A resummed prediction for the longitudinal structure function F_L is presented. It is positive definite and growing with energy at low x and Q^2, where the fixed order results show a significant perturbative instability.

Έναυσμα για τη διενέργειά της αποτέλεσε το γεγονός ότι παρά τη σπουδαιότητα του θέματος λόγω της σημασίας των λεκτικών και μη λεκτικών μέσων επικοινωνίας σε μία σχολική τάξη, παρατηρείται έλλειψη έρευνας στο συγκεκριμένο ερευνητικό πεδίο. Πιο συγκεκριμένα, μελετήθηκαν τα διαφορετικά είδη παύσης-σιωπής, η μη λεκτική επικοινωνία και ο ρόλος της σιωπής μέσα στη σχολική τάξη τόσο από την πλευρά του εκπαιδευτικού όσο και από αυτή του μαθητή. Επιπλέον, στο πλαίσιο της παρούσας εργασίας διενεργήθηκε έρευνα σχετική με τις απόψεις των εκπαιδευτικών για τη σιωπή και τη χρήση της ως διδακτικό εργαλείο κατά τη διάρκεια της διδακτικής διαδικασίας. Στην έρευνα έλαβαν μέρος 122 εκπαιδευτικοί από σχολεία πρωτοβάθμιας εκπαίδευσης από διάφορες περιοχές της Ελλάδας. Οι εκπαιδευτικοί συμπλήρωσαν ένα ερωτηματολόγιο, το οποίο διαμορφώθηκε ύστερα από μελέτη της σχετικής βιβλιογραφίας. Το ερωτηματολόγιο αποτελείτο από δύο μέρη. Στο πρώτο μέρος οι εκπαιδευτικοί κλήθηκαν να απαντήσουν σε ερωτήσεις που αφορούσαν τα δημογραφικά στοιχεία. Στο δεύτερο μέρος απάντησαν σε ερωτήσεις που αφορούσαν τη συχνότητα και τους λόγους χρήσης της σιωπής μέσα στην τάξη. Τα αποτελέσματα έδειξαν ότι οι Έλληνες εκπαιδευτικοί τηρούν μία μετριοπαθή στάση απέναντι στο φαινόμενο της σιωπής παρόλο που οι περισσότεροι δήλωσαν ότι κάνουν χρήση της σιωπής αρκετά συχνά.
description: The aim of the present thesis was to study the phenomenon of pause and silence as a tool of teaching and communication in the school class. The priming of this study was the fact that, despite the importance of this issue because of the significance of verbal and non-verbal means of communication in the school class, there is lack of research in this field. More specifically, we studied the different types of pause and silence, the non-verbal communication and the role of silence in the classroom from both teacher’s and student’s perspective. Moreover, we conducted a research on the teacher’s views about silence and its use as a tool in the teaching process. The survey involved 122 teachers from primary schools from various regions of Greece. Teachers filled out a questionnaire which was consisted of two parts. In the first part, the teachers were asked to answer questions related to demographics. In the second part, they answered in questions regarding the frequency and the reasons of the use of silence in the classroom. The results showed that teachers keep a moderate attitude towards the phenomenon of silence although most of them said that they use silence quite often.
Bayesian multivariate interpolation with missing data and its applications
Creators: name: Sun, Weimin
Publisher: name: University of British Columbia
Year: 2009

description: This thesis develops Bayesian multivariate interpolation theories when there are: (i) data missing-by-design; (ii) randomly missing data; (iii) monotone missing data patterns. Case (i) is fully discussed both theoretically and empirically. A predictive distribution yields a Bayesian interpolator with associated standard deviation, a simultaneous interpolation region, and a hyperparameter estimation algorithm. These results are described in detail. The method is applied to interpolating data from Southern Ontario Pollution. An optimal redesign of a current network is proposed. A cross-validation study is conducted to judge the performance of our method. The method is compared with a Co-kriging approach to which the method is meant to be an alternate. Case (ii) is briefly discussed. An approximation of a matrix T-distribution by a normal distribution is explored for obtaining an approximate predictive distribution. Based on the approximate distribution, an approximate Bayesian interpolator and an approach for estimating hyperparameters by the EM algorithm are described. Case (iii) is only touched on. Only an iterative predictive distribution is derived. Further study is needed for finding ways of estimating hyperparameters.

description: We present experimental results of the first high-precision test of quark-hadron duality in the spin-structure function g_1 of the neutron and $^3$He using a polarized 3He target in the four-momentum-transfer-squared range from 0.7 to 4.0 (GeV/c)^2. Global duality is observed for the spin-structure function g_1 down to at least Q^2 = 1.8 (GeV/c)^2 in both targets. We have also formed the photon-nucleon asymmetry A_1 in the resonance region for 3He and found no strong Q^2-dependence above 2.2 (GeV/c)^2.

description: It is known that there exist two different classes of time dependent solutions in the form of space-like (or S)-branes in the low energy M/string theory. Accelerating cosmologies are known to arise from S-branes in one class, but not in the other where the time-like holography in the dS/CFT type correspondence may be more transparent. We show how the accelerating cosmologies arise from S-branes in the other class. Although we do not get the de Sitter structure in the lowest order supergravity, the near `horizon' ($t\to 0$) limits of these S-branes are the generalized Kasner metric.

Συμπεριφορικη διερεύνηση της χροιϊκής ομοιότητας μουσικών ήχων και συγκριτική μελέτη με χρήση υπολογιστικών μοντέλων της ακουστικής περιφέρειας

description: Ένα από τα βασικά εργαλεία που χρησιμοποιούνται κατά την έρευνα της χροιάς είναι η MDS (MultiDimensionalScaling) ανάλυση. Οι χροιϊκοί χώροι που προκύπτουν από αυτήν συνιστούν μια γεωμετρικής φύσης περιγραφή της χροιάς και αποτελούν το βασικό μοντέλο που χρησιμοποιείται στην ψυχοακουστική. Ερεθίσματα των οποίων οι χροιές είναι σχετικά ίδιες τοποθετούνται κοντά στον χώρο αυτό, ενώ ερεθίσματα που γίνονται αντιληπτά ως διαφορετικά, έχουν μεγαλύτερες αποστάσεις. Οι διαστάσεις του χώρου αυτού συνηθίζεται να συσχετίζονται με επιμέρους φυσικά χαρακτηριστικά των ερεθισμάτων, τα οποία εικάζεται ότι συνδέονται με αντίστοιχα ψυχολογικά μεγέθη. Για ένα σετ ερεθισμάτων που διαφέρουν ως προς την αναλογία τονικού και ενθόρυβου περιεχομένου, εκτελέστηκε πειραματική διερεύνηση σε πραγματικά υποκείμενα και ανάλυση MDS. Οι χροιϊκοί χώροι που προέκυψαν έδειξαν ότι η ευαισθησία δεν είναι σταθερή κατά μήκος του φυσικού συνεχούς. Λαμβάνοντας υπόψιν παλαιότερα δεδομένα που προέκυψαν από μελέτη με χρήση υπολογιστικού μοντέλου, αυτή η μη γραμμικότητα φαίνεται να οφείλεται στη μη γραμμική λειτουργία του ακουστικού οργάνου και όχι σε διεργασίες ανωτέρων σταδίων.
description: MDS (MultiDimensionalScaling) is one of the main tools used in timbre research. Timbre spaces extracted from MDS constitute a geometric description of timbre, being the main model used in psychoacoustics. Stimuli perceived as almost the same lay close to each other in this space, while stimuli perceived as different are located in longer distances to each other. Usually, the dimensions of timbre space are correlated with physical attributes of the stimuli, the later being considered to be connected with psychological characteristics. An experiment and MDS analysis was performed on human subjects for a stiluli set differing in tonal and noise ratio content. Extracted timbre spaces showed that sensitivity is not constant along the physical dimension. Taking into account previous data, resulted from research using model of auditory nerve activity, this non-linearity is likely to be attributed to periphery’s non-linear function, rather than higher mental processes.

description: This is the first paper in a series. We develop a general deformation theory of objects in homotopy and derived categories of DG categories. Namely, for a DG module $E$ over a DG category we define four deformation functors $\Def ^{\h}(E)$, $\coDef ^{\h}(E)$, $\Def (E)$, $\coDef (E)$. The first two functors describe the deformations (and co-deformations) of $E$ in the homotopy category, and the last two - in the derived category. We study their properties and relations. These functors are defined on the category of artinian (not necessarily commutative) DG algebras.

description: Σκοπός της διατριβής ήταν η διερεύνηση των απόψεων των μελλοντικών εκπαιδευτικών πρωτοβάθμιας εκπαίδευσης σχετικά με την αξιολόγηση του έργου του εκπαιδευτικού σε επίπεδο σχολικής μονάδας. Εξετάζεται η έννοια της εκπαιδευτικής αξιολόγησης, της αξιολόγησης του εκπαιδευτικού έργου και του έργου του εκπαιδευτικού καθώς και οι ορισμοί που έχουν διατυπωθεί. Στην συνέχεια αναφέρεται αναλυτικά η αναγκαιότητα της αξιολόγησης στην ανατροφοδότηση και βελτίωση της ποιότητας του εκπαιδευτικού συστήματος αλλά και στην αναβάθμιση της προσωπικής και επαγγελματικής ανάπτυξης του εκπαιδευτικού. Γίνεται εκτενή παρουσίαση των τάσεων που επικρατούν στον ευρωπαϊκό και ελληνικό χώρο για την αξιολόγηση του εκπαιδευτικού και την ποιότητα του έργου του. Τονίζεται ιδιαίτερα ο ρόλος της σωστής επαγγελματικής κατάρτισης του εκπαιδευτικού στην ποιότητα της εκπαίδευσης καθιστώντας έτσι σημαντική τη σχετική ενημέρωσή του από τα προγράμματα σπουδών. Πραγματοποιήθηκε ποσοτική ανάλυση των οδηγών σπουδών των ελληνικών παιδαγωγικών τμημάτων για να διερευνηθεί το περιεχόμενό τους και διαπιστώθηκαν οι απόψεις των φοιτητών προσχολικής και δημοτικής εκπαίδευσης για την αξιολόγηση του έργου τους.
description: The purpose of this study was to investigate the views of future primary school teachers on the evaluation of the work of teaching at school level. Initially, the meaning of educational evaluation is mentioned, the educational assessment and the educator's work, as well as the definitions that have been described. Another issue of great importance that is stressed in detail is the necessity of the evaluation in order to enrich and improve the quality of the educational system and the advancement of the personal and professional evolution of the teacher. Additionally, there is an extensive presentation of the tendencies in the European and Greek area, as far as the teachers evaluation is being concerned. Consequently, the role of the adequate education in accordance with the significance of their continuously educational updating can contribute to the quality of the educational system. A quantitative analysis of the Greek study guide in the Greek pedagogical departments is conducted, in order to stress the content of training evaluation while a structured questionnaire is used according to the views of the preschool and elementary students as far as the assessment of their work is concerned.

description: The workshop aims at providing an international forum for researchers and practitioners from academia, industry, network operators, and service providers to discuss and address the challenges deriving from bringing the technologies from labs to the field with special attention to the effective integration of SDN and NfV functions into a single programmable context. The workshop welcomes contributions from several communities interested in the "virtualization at large" approach, the programmability of network resources, the integration of these functions, the introduction of novel security features. The workshop is particularly interested in real use cases and their implementation. Another topic of great importance is the operation of these platforms. This is a new paradigm, and many operators and other stakeholder need to learn how to fully exploit the capabilities offered. New processes for the management of resources, for the relationship with developers, for the requirements captures from the users have to be identified and consolidated in order to make these platforms a valid instrument for changing the way in which communication services are provided. In addition the workshop aims at considering how these technologies can influence and shape the definition and implementation of the future 5G networks. Contributions that discuss lessons learnt and best practices, describe practical deployment and implementation experiences, and demonstrate innovative use-cases are especially encouraged for presentation and publication.

description: Η επικοινωνία, η επαφή και η αποδοχή είναι ίσως η βασικότερη ανάγκη του ανθρώπου στην κοινωνική του ζωή. Κάθε άνθρωπος ορίζει την ποσότητα και την ποιότητα της επικοινωνίας του, ανάλογα με τα βασικά χαρακτηριστικά του και την επιθυμία που έχει για να αλληλεπιδράσει και να ενταχθεί στο κοινωνικό περιβάλλον. Αποτελεί μία ικανότητα του ανθρώπου, τα χαρακτηριστικά της οποίας διαμορφώνονται από την βρεφική ηλικία και τον συνοδεύουν εφόρου ζωής. Η αποδοχή, η ένταξη, η επικοινωνία, η φιλική ή η ερωτική σχέση προσδιορίζουν κάποιες από τις κοινωνικές δεξιότητες του ατόμου σε οποιαδήποτε ηλικία. Ένα άτομο που είναι αποδεκτό, στον τομέα των κοινωνικών σχέσεων αλληλεπιδρά με τους συνομηλίκους του και δημιουργεί σχέσεις αυθόρμητα. Δεν συμβαίνει, όμως ,το ίδιο και για τα άτομα με νοητική ανεπάρκεια. Ποιοι είναι αυτοί οι περιορισμοί που εμποδίζουν την ανάπτυξη της επικοινωνίας; Κάτω από ποιες προϋποθέσεις και σε τι πλαίσιο μπορεί ένα άτομο να νιώσει αποδεκτό και να αναπτύξει σχέσεις με τους συνομηλίκους του; Στην παρούσα έρευνα παρουσιάζεται ο σχεδιασμός και η υλοποίηση ενός προγράμματος παρέμβασης με στόχο την κοινωνική ένταξη ενός ενήλικου ατόμου στην ομάδα χορού. Αποτελεί μία 12μηνη ερευνητική προσπάθεια, σε απόλυτη συνεργασία με ένα δημόσιο κέντρο φιλοξενίας ατόμων με νοητική ανεπάρκεια, με στόχο την κοινωνική αλληλεπίδραση με άτομα εκτός της δημόσιας κατοικίας στην οποία κατοικεί. Στην συνέχεια καταγράφονται λεπτομερώς τόσο ο σχεδιασμός όσο και η υλοποίηση αυτού του ερευνητικού προγράμματος.
description: The ability to contact and communicate and the sense of feeling accepted by the surrounding social environment are critical qualities determining the social life of a human being. The quantity and quality of human communication are defined by each individual’s characteristics and the desire to be adapted. These skills are developed during the infancy and the social acceptance, communication, friendly relationships, love affairs evince their efficiency. Under the condition that a person is accepted, social interaction and relationships bonding happens spontaneously. However, this is not the case for people with impaired cognitive functioning. What is lying at the heart of this lack of communication abilities? What are the circumstances which can lead a person to feel accepted and able to bond relationships? The planning and implementation of an intervention schedule with the aim of achieving the join and acceptance of a person with cognitive impairment in a dance group are presented in this report. This 12-month research study was held with fully collaboration with a public hospitality centre for people with mental disabilities under the objective to achieve social interaction outside the home environment. In this report, the planned schedule and the steps are thoroughly presented.
