description: A small fraction of the gravitational-wave (GW) signals that will be detected by second and third generation detectors are expected to be strongly lensed by galaxies and clusters, producing multiple observable copies. While optimal Bayesian model selection methods are developed to identify lensed signals, processing tens of thousands (billions) of possible pairs of events detected with second (third) generation detectors is both computationally intensive and time consuming. To mitigate this problem, we propose to use machine learning to rapidly rule out a vast majority of candidate lensed pairs. As a proof of principle, we simulate non-spinning binary black hole events added to Gaussian noise, and train the machine on their time-frequency maps (Q-transforms) and localisation skymaps (using Bayestar), both of which can be generated in seconds. We show that the trained machine is able to accurately identify lensed pairs with efficiencies comparable to existing Bayesian methods.

description: Mixtures of lipids and cholesterol are commonly used as model systems for studying the formation of liquid-ordered ($L_o$) domains in heterogeneous biological membranes. The simplest model system exhibiting coexistence between $L_o$ domains and a liquid-disordered ($L_d$) matrix is that of a binary mixture of saturated lipids like DPPC and cholesterol (Chol). DPPC/Chol mixtures have been investigated for decades both experimentally, theoretically, and recently also by means of atomistic simulations. Here, we present a minimal lattice model that captures the correct behavior of this mixture across multiple scales. On the macroscopic scales, we present simulation results of mixtures of thousands of lipids and Chol molecules which show excellent agreement with the phase diagram of the system. The simulations are conducted on timescales of hundreds of microseconds and show the morphologies and dynamics of the domains. On the molecular scales, the simulations reveal local structures similar to those recently seen in atomistic simulations, including the formation of gel-like nano-domains ($\sim$ 1-10 nm) within larger Chol-rich $L_o$ domains ($\sim$ 10-100 nm). The observed multi-scale behavior is related to the tendency of Chol to induce ordering of acyl chains on the one hand, and disrupt their packing with each other, on the other hand.

description: Η μελέτη αυτή ερευνά εις βάθος τις οργανώσεις της κοινωνίας των πολιτών (ΟΚΠ) - μη κερδοσκοπικές, εθελοντικές οντότητες ξεχωριστές από το κράτος, συμπεριλαμβανομένων των κοινοτικών οργανώσεων και των μη κυβερνητικών οργανώσεων (ΜΚΟ). Αν και το συγκεκριμένο πεδίο μελέτης είναι ιδιαίτερα ανεπτυγμένο, ελάχιστη έρευνα έχει γίνει σχετικά με τον τρόπο με τον οποίο η κοινωνία των πολιτών χρησιμοποιεί ειδικά τα πολυμεσικά εργαλεία για την οικοδόμηση ειρήνης σε περιοχές μετά από συγκρούσεις. Σκοπός της έρευνας είναι να αναλύσει με ποιο τρόπο οι ΟΚΠ σε κοινωνίες μετά από συγκρούσεις αξιοποιούν τα μέσα επικοινωνίας για την προώθηση διαδικασιών οικοδόμησης της ειρήνης. Για τους σκοπούς της έρευνας επιλέχθηκαν οι ΟΚΠ που προωθούν την ειρήνη στη Βοσνία-Ερζεγοβίνη αναλύοντας σε βάθος μέσα από ημιδομημένες συνεντεύξεις την τρέχουσα χρήση των μέσων ενημέρωσης, την αποτελεσματικότητά και την εμβέλειά τους. Οι συνεντεύξεις σχεδιάστηκαν για να αξιολογηθούν οι στόχοι των ΟΠΚ, η δομή, ο τύπος του παραγόμενου περιεχομένου και η επίτευξη των στόχων. Τα αποτελέσματα αυτής της μελέτης αποκαλύπτουν σε ποιο βαθμό οι ΟΚΠ συμβάλλουν στις προσπάθειες οικοδόμησης της ειρήνης σε περιοχές μετά από συγκρούσεις και σε ποια τα πεδία ενδέχεται βελτίωση προκειμένου να αναπτυχθεί η επικοινωνία και η χρήση των πολυμεσικών εργαλείων στην κοινωνία των πολιτών
description: This study aims to dive deeper into the field of research regarding how civil society organizations (CSOs)—nonprofit, voluntary entities separate from the state, including community-based organizations and non-governmental organizations (NGOs)—use communications and multimedia in their work. While there is current research on its existence, there has been little research conducted on how civil society uses multimedia specifically for peacebuilding efforts in post-conflict areas. The goal of this research is to analyze in which ways CSOs in post-conflict societies utilize communications to promote peacebuilding processes. A selected number of peacebuilding CSOs in Bosnia and Herzegovina provided in-depth, semi-structured interviews in order to analyze current media use and its effectiveness and reach. The interviews were designed in order to assess CSO objectives, structure, type of content produced and reach. Results of this study illuminate to what extent CSOs are contributing to peacebuilding efforts in post-conflict areas, and what are the largest areas of improvement in order to develop communications and multimedia use within civil society

description: Αυτή η μελέτη χρησιμοποιεί τη θεματική ανάλυση για να κατανοήσει πώς οι οργανώσεις των μέσων ενημέρωσης των νέων χρησιμοποιούν τις παιδαγωγικές τους για να ενισχύσουν την ανάπτυξη των ενηλίκων και της κοινότητας. Συγκεκριμένα, αυτή η έκθεση αναλύει 16 οργανώσεις των μέσων ενημέρωσης των νέων σε όλες τις Ηνωμένες Πολιτείες και βασίζεται σε ημιδομημένες συνεντεύξεις Εκτελεστικών Διευθυντών (ΕΔ), μελών του προσωπικού, νεολαίας και αποφοίτων. Ο τριγωνισμός διαφόρων προοπτικών από αυτές τις συνεντεύξεις παρουσιάζει ένα πλούσιο σύνολο δεδομένων για τους τις οργανώσεις και τη χρήση της δημοσιογραφίας και των νέων μέσων, καθώς και τον αντίκτυπο στη νεολαία και την κοινότητα. Η συνδεσιμότητα της κοινότητας, η ανάπτυξη των νέων και τα μέσα ενημέρωσης ως μια μορφή αφηγηματικής αφήγησης είναι σημαντικά θέματα συζήτησης σε αυτά τα αποτελέσματα. Τα ευρήματα αποκαλύπτουν ότι οι οργανώσεις των μέσων ενημέρωσης των νέων δημιουργούν ισχυρές συνδέσεις στην κοινότητα και ενισχύουν την ανάπτυξη των νέων, συμπεριλαμβανομένων ακαδημαϊκών επιτευγμάτων και κοινωνικο-συναισθηματικής υγείας, μέσω μαθησιακών εμπειριών (PBL) και εμπειριών που οδηγούν στη νεολαία, στρατηγικών κοινοτικών συνεργασιών, ολιστικών και συνεργατικών προσεγγίσεων, δίκτυα ανάπτυξης και ενδυνάμωσης της έκφρασης
description: This study uses thematic analysis to understand how youth media organizations (YMOs) utilize their pedagogies to increase adolescent and community development. Specifically, this report analyzes 16 YMOs across the United States and draws upon semi-structured interviews of Executive Directors (EDs), staff members, youth, and alumni. The triangulation of various perspectives from these interviews presents a rich data set about the YMOs and their use of journalism and new media, as well as the impact upon the youth and community. Community connectedness, youth development, and media as a form of narrative storytelling are important topics of discussion within these results. Findings reveal that YMOs create strong community connections and strengthen youth development, including academic achievement and socio-emotional health, through project-based learning (PBL) and youth-drive experiences, strategic community partnerships, holistic and collaborative approaches, pipelines of growth, and the empowerment of expression

description: We present deep and accurate Near-Infrared (NIR) photometry of the Galactic Globular Cluster (GC) Omega Cen. Data were collected using the Multi-Conjugate Adaptive Optics Demonstrator (MAD) on VLT (ESO). The unprecedented quality of the images provided the opportunity to perform accurate photometry in the central crowded regions. Preliminary results indicate that the spread in age among the different stellar populations in Omega Cen is limited.

description: Το υπερφυές «σημείο» της μυροβλυσίας υπήρξε κριτήριο για την αναγνώριση της αγιότητας πλήθους αγίων πατέρων της Εκκλησίας μας. Στα πλαίσια του ΠΜΣ «Σπουδές στην Ιστορία, την Πνευματικότητα, την Τέχνη και τη Μουσική Παράδοση του Αγίου Όρους», αντικείμενο της διπλωματικής μας υπήρξε η διερεύνηση του φαινομένου της μυροβλυσίας των ιερών λειψάνων και των χώρων ταφής οσίων μοναχών που εγκαταβίωσαν στο Άγιο Όρος. Στο πρώτο μέρος της εργασίας μας προσεγγίσαμε θεολογικά το φαινόμενο της μυροβλυσίας και μελετήσαμε το βίο των μυροβλυτών αγιορειτών οσίων, προσπαθώντας να ερμηνεύσουμε γιατί αξιώθηκαν από το Θεό με το θαυμαστό αυτό φαινόμενο. Στην προσπάθεια μας να αναδείξουμε περαιτέρω το φιλόθεο και αγγελικό του βίου των αγιορειτών μυροβλυτών “μαρτύρων” του μοναχισμού, στο δεύτερο μέρος της εργασίας μας ασχοληθήκαμε με το βίο και την πολιτεία του οσίου Θεοφίλου του Μυροβλύτη, μιας από τις σπουδαιότερες μορφές της αγιορείτικης βιβλιογραφίας του 16ου αιώνα και λαμπρό παράδειγμα μετάνοιας, ταπεινότητας και ασκητισμού. Συγχρόνως, και μελετώντας όλες τις πτυχές του βίου του οσίου, εξετάσαμε και μερικά ιστορικά και θεολογικά στοιχεία του ησυχαστικού περιβάλλοντος εγκαταβίωσής του αλλά και του ευρύτερου περιβάλλοντος του Αγίου Όρους, το οποίο επέδρασε σημαντικά και διαμόρφωσε διαχρονικά την προσωπικότητα και το έργο πολλών μεγάλων οσίων μορφών
description: The supernatural phenomenon of Myroblism (:the flow of the “oil of saints” or “holy water”, an aromatic liquid very much like myrrh and the holy essence that emanates from the bodies of saints) has been a strong evidence of the sainthood of many holy fathers of our Church. Within the framework of the program "Studies in the History, Spirituality, Art and Musical Tradition of Mount Athos", our goal was to investigate the phenomenon of myrrh flowing out of the sacred relics and burial places of monks who had lived in the area of the Holy Mountain. In the first part of our work we approached the phenomenon of myrrh exudation and studied the holy life of the Athonite myroblytes, trying to explain why they were blessed with that rare gift. In an effort to further highlight the good and angelic life of the Athonite “martyrs” of monasticism, in the second part of our work we dealt with the life and works of Saint Theophilos the Myroblyte, one of the most important bibliographers of the sixteenth century on Mount Athos and an excellent example of repentance, humility and asceticism. Studying all aspects of the life of the saint, we also examined some of the historical and theological elements of the ascetic environment of Mount Athos, which greatly influenced and shaped the personalities and works of many great Athonite monks

description: We calculate the eigenvalue distribution of the Faddeev-Popov operator in Coulomb gauge QCD using quenched SU(3) lattice simulation. In the confinement phase, the density of the low-lying eigenvalues increases with lattice volume, and the confinement criterion is satisfied. Moreover, even in the deconfinement phase, the behavior of the FP eigenvalue density is qualitatively the same as in the confinement phase. This is consistent with the fact that the color-Coulomb potential is not screened in the deconfined phase.

description: Moiré patterns are additional, long-range periodicities in twisted crystalline bilayers. They are known to fundamentally change the electronic states of the layers, but similar effects on their mechanical and vibrational properties have not been discussed so far. Here we show that the Moiré potential shifts the radial breathing mode in double walled carbon nanotubes (DWCNTs). The change of frequency is expected to be proportional to the shift in optical transition energies, which are induced by the Moiré patterns. To verify our model we performed resonant Raman scattering on purified and sorted semiconducting DWCNTs. We find that the radial breathing mode shifts up to 14 cm$^{-1}$ higher in energy followed by optical transitions energies displacement up to 200 meV to lower energies, compared to the single-walled tubes. We show how to identify the strong coupling condition in DWCNTs from their phonon frequencies and construct a Kataura plot to aid their future experimental assignment.

description: The spectral properties of operators formed from generators of the q-Onsager non-Abelian infinite dimensional algebra are investigated. Using a suitable functional representation, all eigenfunctions are shown to obey a second-order q-difference equation (or its degenerate discrete version). In the algebraic sector associated with polynomial eigenfunctions (or their discrete analogues), Bethe equations naturally appear. Beyond this sector, where the Bethe ansatz approach is not applicable in related massive quantum integrable models, the eigenfunctions are also described. The spin-half XXZ open spin chain with general integrable boundary conditions is reconsidered in light of this approach: all the eigenstates are constructed. In the algebraic sector which corresponds to special relations among the parameters, known results are recovered.

description: O άγιος Συμεών στη διδασκαλία του περί πνευματικής πατρότητας ακολούθησε πιστά την πατερική και κανονική παράδοση. Η καταφυγή στον πνευματικό πατέρα είναι απαραίτητη για τον πιστό που θέλει να προκόψει στον πνευματικό του βίο. Η πνευματική πατρότητα ως φάρμακο ψυχών είναι απαραίτητη για τη σωτηρία. Ο πνευματικός Πατέρας πρέπει να αποτελεί ηθικό πρότυπο για τους πιστούς και να ζει κατά Χριστό. Ο Επίσκοπος δια της αποστολικής διαδοχής είναι πνευματικός πατέρας μετά Θεόν. Ως τελών τα μυστήρια μεταδίδει την θεία χάρη στο ποίμνιο και τα πνευματικά δώρα του εν Χριστώ βίου. Το μυστήριο της μετάνοιας τελείται μόνο από τους έχοντες την εξουσία να συγχωρούν τις αμαρτίες, δηλαδή τους Επισκόπους. Ο ίδιος ο Χριστός μεταβίβασε την εξουσία του δεσμείν και λύειν στους αποστόλους και δια της αποστολικής διαδοχής στους Επισκόπους. Για λόγους πρακτικούς και επειδή δεν είναι πάντοτε δυνατόν οι πιστοί να εξομολογούνται στον οικείο επίσκοπο, δύνανται να τελούν την εξομολόγηση και οι ιερείς, αλλά πάντα κατόπιν αδείας (ενταλτηρίου) και ευλογίας του επισκόπου. Η μοναδική θέση που επέχει ο Επίσκοπος για την τοπική Εκκλησία αντιστοιχεί με αυτήν που επέχει ο Ηγούμενος για την Ιερά Μονή του
description: Saint Symeon, archbishop of Thessalonica, in his teaching of spiritual fatherhood adopted the patristic and canonical tradition. Addressing to the spiritual father is essential for the believer who wants to advance in his spiritual life. Spiritual fatherhood as a remedy for souls is essential for the salvation of the human nature. The spiritual Father must be a moral model for believers and live according the example of Jesus Christ. The Bishop by the apostolic succession is a spiritual father after God for a local Church. Indeed, with the celebration of the sacraments the Bishop transmit the divine grace and the spiritual gifts of Christ through the flock. The sacrament of repentance is celebrated only by those who have the power to forgive sins, the Bishops. Christ Himself transferred His power to forgive sins to the Apostles and through the Apostolic succession to the Bishops. For practical reasons, and because it was not always possible for the flock to confess to the local bishop, confession may be made by the priests, but always with the permission and blessing of the bishop. The unique position of the Bishop for the local Church corresponds to that of the Abbot for his Holy Monastery and the monastic community

description: Intermittent fluctuations in the boundary of magnetically confined plasmas are investigated by numerical turbulence simulations of a reduced fluid model describing the evolution of the plasma density and electric drift vorticity in the two-dimensional plane perpendicular to the magnetic field. Two different cases are considered, one describing resistive drift waves in the edge region and another including only the interchange instability due to unfavorable magnetic field curvature in the scrape-off layer. Analysis of long data time series obtained by single-point recordings are compared to predictions of a stochastic model describing the plasma fluctuations as a super-position of uncorrelated pulses. For both cases investigated, the radial particle density profile in the scrape-off layer is exponential with a radially constant scale length. The probability density function for the particle density fluctuations in the far scrape-off layer has an exponential tail. Radial motion of blob-like structures leads to large-amplitude bursts with an exponential distribution of peak amplitudes and the waiting times between them. The average burst shape is well described by a two-sided exponential function. The frequency power spectral density of the particle density is simply that of the average burst shape and is the same for all radial positions in the scrape-off layer. The fluctuation statistics obtained from the numerical simulations are in excellent agreement with recent experimental measurements on magnetically confined plasmas. The statistical framework defines a new validation metric for boundary turbulence simulations.

Effects of exercise modality on metabolic rate, body composition, dietary intake, and eating behaviour

Publisher: name: University of British Columbia
Year: 2008

description: This study was designed to investigate the effects of exercise as a strategy for weight management in overweight women. Specifically, the effects of exercise modality on metabolic rate, body composition, dietary intake, and eating behaviour were examined. Participants included 41 overweight, sedentary females aged 25 to 49 years, who had a defined history of dieting. Experimental (n=26) and control (n=15) participants were recruited separately. Participants in the experimental group were randomly assigned to either an endurance- or a resistance-training exercise class. Exercise classes designed for a sedentary population were scheduled three times per week for a duration of three months. Pre- and post-intervention measures included resting energy expenditure (REE), anthropometry (height, weight, 8 skinfolds and 6 girth measurements), a three-day diet record, and the Three-Factor Eating Questionnaire. Results indicated that exercise modality had no effect on REE, dietary intake, or eating behaviour. Exercise, regardless of modality, had a significant effect on body composition (p=0.0001) as shown by a significant decrease in the sum of skinfolds for the two exercise groups relative to the control group (p<0.0001). No differences in fat-free mass were observed between groups. Regardless of modality, exercise also resulted in an increased estimated VO2 max (p=0.012), based on a one-mile walking test. The pattern of weight change of the groups was different (p=0.029) over the three month period. Whereas the exercise groups maintained their weight, the control group gained weight (approximately 2.5 kg). Thus, although exercise modality had no effect, the benefits of exercise per se, such as decreased body fat, increased fitness level, and weight maintenance, were observed in this population. Implications for future studies concerning exercise prescription, exercise adherence, and weight management include preferences for walking as a mode of exercise and the importance of incorporating factors such as group homogeneity, social networking, commitment to a goal, and a leader with a health-related background into an exercise program. Also, it was shown that exercise prevents seasonal weight gain that might otherwise occur in the absence of exercise.
Motion of a gyroscope on a closed timelike curve

description: We consider the motion of a gyroscope on a closed timelike curve (CTC). A gyroscope is identified with a unit-length spacelike vector - a spin-vector - orthogonal to the tangent to the CTC, and satisfying the equations of Fermi-Walker transport along the curve. We investigate the consequences of the periodicity of the coefficients of the transport equations, which arise from the periodicty of the CTC, which is assumed to be piecewise $C^2$. We show that every CTC with period $T$ admits at least one $T-$periodic spin-vector. Further, either every other spin-vector is $T-$periodic, or no others are. It follows that gyroscopes carried by CTCs are either all $T-$periodic, or are generically not $T-$periodic. We consider examples of spacetimes admitting CTCs, and address the question of whether $T-$periodicity of gyroscopic motion occurs generically or only on a negligible set for these CTCs. We discuss these results from the perspective of principles of consistency in spacetimes admitting CTCs.

Subjects: Taxpayers' education, Voluntary tax compliance

description: This paper carefully examines the influence of taxpayers' education on voluntary tax compliance in Benin City, Edo State.  The study being empirical evaluated taxpayer education with the aid of effective seminars and handbooks/bills. The study gathered relevant data with the aid of a well-structured questionnaire administered to taxpayers who are in the business of small and medium-sized enterprises. A total of seventy-seven (77) taxpayers were carefully selected for the study, upon which the Ordinary least square regression method was used to analyze the data gathered. Premised on the analysis, the paper concluded that the effective use of seminars and handbooks/bills significantly influences voluntary tax compliance in the city and therefore recommends the need for the relevant tax authority to promote taxpayers' education as this has a direct relationship with voluntary taxpayers compliance and as well would improve the revenue of the government

description: By linking to external websites, Wikipedia can act as a gateway to the Web. To date, however, little is known about the amount of traffic generated by Wikipedia's external links. We fill this gap in a detailed analysis of usage logs gathered from Wikipedia users' client devices. Our analysis proceeds in three steps: First, we quantify the level of engagement with external links, finding that, in one month, English Wikipedia generated 43M clicks to external websites, in roughly even parts via links in infoboxes, cited references, and article bodies. Official links listed in infoboxes have by far the highest click-through rate (CTR), 2.47% on average. In particular, official links associated with articles about businesses, educational institutions, and websites have the highest CTR, whereas official links associated with articles about geographical content, television, and music have the lowest CTR. Second, we investigate patterns of engagement with external links, finding that Wikipedia frequently serves as a stepping stone between search engines and third-party websites, effectively fulfilling information needs that search engines do not meet. Third, we quantify the hypothetical economic value of the clicks received by external websites from English Wikipedia, by estimating that the respective website owners would need to pay a total of $7--13 million per month to obtain the same volume of traffic via sponsored search. Overall, these findings shed light on Wikipedia's role not only as an important source of information, but also as a high-traffic gateway to the broader Web ecosystem.

description: Metamaterials and metasurfaces are designed by periodically arranged subwavelength geometries, allowing a tailored manipulation of the electromagnetic response of matter. Here, we exploit temporal variations of permittivity inside subwavelength geometries to propose the concept of spatiotemporal meta-atoms having time-dependent properties. We exploit isotropic-to-anisotropic temporal boundaries within spatially subwavelength regions where their permittivity is rapidly changed in time. In so doing, it is shown how resulting scattered waves travel in directions that are different from the direction of the impinging wave, and depend on the values of the chosen anisotropic permittivity tensor. To provide a full physical insight of their performance, multiple scenarios are studied numerically such as the effect of using different values of permittivity tensor, different geometries of the spatiotemporal meta-atom and time duration of the induced isotropic-to-anisotropic temporal boundary. The intrinsic asymmetric response of the proposed spatiotemporal meta-atoms is also studied demonstrating, both theoretically and numerically, its potential for an at-will manipulation of scattered waves in real time. These results may open new paradigms for controlling wave-matter interactions and may pave the way for the next generation of metamaterials and metasurfaces by unleashing their potential using four-dimensional (4D) unit cells.

description: We report on the calculation of the cyclotron spin-flip excitation (CSFE) in a spin-polarized quantum Hall system at unit filling. This mode has a double-exciton component which contributes to the CSFE correlation energy but can not be found by means of a mean field approach. The result is compared with available experimental data.

description: Many qubit implementations are afflicted by correlated noise not captured by standard theoretical tools that are based on Markov approximations. While independent gate operations are a key concept for quantum computing, it is actually not possible to fully describe noisy gates locally in time if noise is correlated on times longer than their duration. To address this issue, we develop a method based on the filter function formalism to perturbatively compute quantum processes in the presence of correlated classical noise. We derive a composition rule for the filter function of a sequence of gates in terms of those of the individual gates. The joint filter function allows to efficiently compute the quantum process of the whole sequence. Moreover, we show that correlation terms arise which capture the effects of the concatenation and thus yield insight into the effect of noise correlations on gate sequences. Our generalization of the filter function formalism enables both qualitative and quantitative studies of algorithms and state-of-the-art tools widely used for the experimental verification of gate fidelities like randomized benchmarking, even in the presence of noise correlations.

description: The light curves (LC) for Supernova (SN) can be modeled adopting the conversion of the flux of kinetic energy into radiation. This conversion requires an analytical or a numerical law of motion for the expanding radius of the SN. In the framework of conservation of energy for the thin layer approximation we present a classical trajectory based on a power law profile for the density, a relativistic trajectory based on the Navarro--Frenk--White profile for the density, and a relativistic trajectory based on a power law behaviour for the swept mass. A detailed simulation of the LC requires the evaluation of the optical depth as a function of time. We modeled the LC of SN~1993J in different astronomical bands, the LC of GRB 050814 and the LC GRB 060729 in the keV region. The time dependence of the magnetic field of equipartition is derived from the theoretical formula for the luminosity.

A three part project consisting of graduating essay, student internship report, studio work in painting
Creators: name: Weaver, Carla B.
Publisher: name: University of British Columbia
Year: 2008

description: My interdisciplinary studies have concentrated on the practice of art, the theory of art and the business of art by combining the disciplines of art history, painting and arts administration through the Faculties of Arts and Commerce and Business Administration. This three part project replaced a traditional thesis in order to best explore these disciplines. Part I is a graduating essay, which discusses a management strategy for the 21st century for public art galleries in Canada. It calls for an interdisciplinary approach to management, so that Directors can combat the issues of reduced public funding, a work force composed of paid workers and volunteers, and a heightened awareness that, in order to survive, galleries must understand and communicate with all of their constituents including artists, audiences, volunteers, employees, politicians, private donors and corporate sponsors, and boards of directors. Part II of this paper describes my internship at the Vancouver Art Gallery, which took place from October 1992 to April 1993. The internship was part of my Masters program studies, and involved working on two projects: "Day Without Art" and "Art in Bloom." These two projects exposed me to project management within the art gallery context and to working with volunteers, artists and gallery staff. The report contained within this project describes my involvement in these two projects, and offers conclusions and recommendations. Part III of the project involved studio painting. Photos of 23 works that were completed during my study program are included, along with a description of the work. By studying painting, interning at the Gallery, and conducting research in arts administration and art history, I was able to gain a multidimensional point of view about the visual arts, which I believe will be invaluable for a career in the arts, and was an enjoyable and stimulating study program.

description: Correlated, non-Markovian noise is present in many solid-state systems employed as hosts for quantum information technologies, significantly complicating the realistic theoretical description of these systems. In this regime, the effects of noise on sequences of quantum gates cannot be described by concatenating isolated quantum operations if the environmental correlation times are on the scale of the typical gate durations. The filter function formalism has been successful in characterizing the decay of coherence under the influence of such classical, non-Markovian environments and here we show it can be applied to describe unital evolution within the quantum operations formalism. We find exact results for the quantum process and a simple composition rule for a sequence of operations. This enables the detailed study of effects of noise correlations on algorithms and periodically driven systems. Moreover, we point out the method's suitability for numerical applications and present the open-source Python software package filter_functions. Amongst other things, it facilitates computing the noise-averaged transfer matrix representation of a unital quantum operation in the presence of universal classical noise for arbitrary control sequences. We apply the presented methods to selected examples.

description: Often a modification of microscopic symmetry in a system can result in a dramatic change in its macroscopic properties. Here we report that symmetry breaking by a tube-threading magnetic field can drastically increase the photoluminescence quantum yield of semiconducting single-walled carbon nanotubes, by as much as a factor of six, at low temperatures. To explain this striking connection between seemingly unrelated properties, we have developed a comprehensive theoretical model based on magnetic-field-dependent one-dimensional exciton band structure and the interplay of strong Coulomb interactions and the Aharonov-Bohm effect. This conclusively explains our data as the first experimental observation of dark excitons 5-10 meV below the bright excitons in single-walled carbon nanotubes. We predict that this quantum yield increase can be made much larger in disorder-free samples.

description: H παρούσα εργασία μελετά το αντι-μνημονιακό ντοκιμαντέρ, το οποίο θεωρείται ως προϊόν της ελληνικής κρίσης. Η εξήγηση της κρίσης από τα παραδοσιακά μέσα θεωρήθηκε εν πολλοίς μη αντικειμενική αν όχι πολιτικά μεροληπτική. Συνεπώς, οι δημιουργοί των ντοκιμαντέρ που θα εξεταστούν προσπάθησαν να εξηγήσουν την κρίση με έναν πιο αντικειμενικό τρόπο, κατά τα δικά τους πιστεύω. Η πολιτική οικονομία της παραγωγής των ντοκιμαντέρ αυτών είναι ιδιαίτερα ενδιαφέρουσα, αφού χρησιμοποιήθηκαν εναλλακτικοί τρόποι για τη χρηματοδότηση, την διανομή και την προβολή τους. Αν και ο σκοπός των δημιουργών είναι να παρουσιάσουν την κρίση με αντικειμενικότητα, συχνά δεν το καταφέρνουν, και επομένως τα ντοκιμαντέρ αυτά εμπεριέχουν διάφορα στοιχεία λαϊκισμού, συνωμοσιολογίας και ριζοσπαστισμού
description: This dissertation aims at exploring the “anti-austerity” documentary, which is considered to be a product of the Greek economic crisis. Although, when the crisis began, the country’s mainstream media offered a plethora of explanations of it, they were considered to be, and in many cases were, partisan. Therefore, the creators of the “anti-austerity” documentaries tried to present the crisis and its events in a more truthful, non partisan scope. In an epoch of skepticism towards the mainstream Greek media, the “anti- austerity” documentary used alternative ways for its funding, production and distribution. It can, therefore, be classified as an “alternative medium”. However, the alternative ways of producing these documentaries, as well as the anti-authority, mostly leftist background of the majority of their creators, have given a subjective and rather radical character to the genre. Also, although the basic intention of the producers was to “reveal the truth”, those documentaries often fail at explaining the details of the crisis. Instead, they get caught in a manicheist way of interpreting it, where a small number of powerful economic elites is ruling the country and the world, and people are powerless in the wake of neo-liberalism. This way of seeing the world is argued to be both populist and conspiratorial. Conspiracy theories and populism generally flourished during the Greek economic crisis. However, the populist and conspiratorial discourse that was mainly researched academically was the one of the political right and far right. Therefore, the goal of this dissertation is to investigate the conspiracy theories and the populist ideas that flourished as products of the leftist political discourse during the Greek economic crisis, as presented in the “anti-austerity” documentaries that will be examined

description: Στην παρούσα μελέτη εστιάσαμε στους τρόπους αναπαράστασης του παρελθόντος όπως αυτοί αποτυπώνονται σε κείμενα των Φάις και Sebald. Με αφετηρία την ιδιότυπη γραφή των δύο συγγραφέων, που ορίσαμε ως κολάζ ντοκουμέντων και λογοτεχνικών ειδών στα διευρυμένα πλαίσια της μεταμοντέρνας λογοτεχνίας, επιχειρήσαμε να ανιχνεύσουμε τους συσχετισμούς μεταξύ του τρόπου αυτού και των θεματικών της ιστορίας και της μνήμης. Η διαλογικότητα που αναδύεται μέσα από την πληθυντικότητα και ετερογένεια των λόγων στα κείμενα κολαζιακής λογοτεχνίας, αναδεύει προβληματισμούς που αφορούν τον αλληλο-προσδιορισμό της Ιστορίας με την κοινωνία και την ταυτότητα, συλλογική και ατομική, καθώς και τη λογική διαμεσολάβησης και κατασκευής που εμπεριέχουν οι αναπαραστάσεις του παρελθόντος. Κατά τον τρόπο, που η μεταδομιστική θεωρία και η μεταμοντέρνα πολιτισμική λογική ανέδειξαν τη κινητικότητα και πληθυντικότητα του νοήματος, ανάμεσα στα σημεία και τα σημαινόμενα, στο σύνολο των προεκτάσεων του κόσμου και της κοινωνίας, αντικρύζουμε και τα κείμενα κολάζ, και δη εκείνα με ιστορικό περιεχόμενο, να αναπαριστούν τη κινητικότητα, ρευστότητα και διαλογικότητα, των νοημάτων και αναπαραστάσεων του παρελθόντος και της ιστορίας, των αφηγημάτων και των συμβάσεων του λόγου ακόμη. Στόχος της εργασίας είναι να αναδειχθούν όλοι αυτοί οι διάλογοι και οι συσχετισμοί στην κατασκευή της αναπαράστασης του παρελθόντος και στην αλληλεπίδραση που αυτή φέρει με το άτομο και την κοινωνία
description: The present thesis focuses on the ways of representation of the past as they are depicted in Fais’ and Sebald’s works. Having the aforementioned authors’ distinctive writing style of as a point of reference, which is defined as a collage of documents and literary genres in the extended context of postmodern literature, we attempted to trace the correlations between their writing styles and the fields of History and Memory. The dialogism, which emerges through the plurality and the heterogeneity of the discourses in the collage literature, raises concerns regarding the interaction and definition of History in terms of society, the individual and collective identity and regarding the rationality of intervention and formulation that are embedded in the representations of the past. The poststructuralism and the postmodern cultural logic demonstrate the fluidity and plurality of the meaning of the signs and signifiers in the world’s and society’s aspects. Based on that way of demonstration, we examine the collage works and especially those of historical content that present the flexibility, fluidity, and dialogism of the meaning, of the representations of the past and History, of the narratives, and the discourse genres. This thesis aims to highlight all these dialogues and correlations of the structure of the representation of the past and its interaction with the individual and society
