interfacea: open-source library for protein interface analysis
Creators: name: Rodrigues, João

Publisher: name: F1000 Research Limited
Year: 2019

description: Protein interactions are central to most processes in biology. Understanding why and how these interactions translate to biological function requires a detailed analysis of their 3D structures. Often, these analyses involve the identification of chemical features such as hydrogen bonds and ionic interactions, as well as quantitative measurement of their contribution to the overall stability of the system. Here, we present interfacea, a software library written in Python to facilitate the analysis of chemical and energetic features of macromolecular interfaces. Besides implementing standard algorithms to identify a variety of chemical interactions, interfacea is built on the OpenMM simulation engine to allow high-performance energy calculations that can identify both hotspots and sources of strain in the 3D structure. Our code complies to the PEP8 standards and is available under an open-source license on GitHub. As such, we hope that interfacea not only facilitates routine analyses of the 3D structure of protein interactions, but serves also as a building block for more advanced tools in molecular docking and design.

description: We report on precision measurements of the frequency of the radial compression mode in a strongly interacting, optically trapped Fermi gas of Li-6 atoms. Our results allow for a test of theoretical predictions for the equation of state in the BEC-BCS crossover. We confirm recent quantum Monte-Carlo results and rule out simple mean-field BCS theory. Our results show the long-sought beyond-mean-field effects in the strongly interacting BEC regime.

A passage to premodernity : Carl Sauer repositioned in the field
Creators: name: Skeels, Anna Clare
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is an attempt to mediate between the different perspectives on Carl Sauer and his work that fix him in the “field” of geography. By repositioning Sauer literally in the “field" in Mexico (and later, in South America) through a reading of his correspondence and fieldnotes, I hope to open up Sauer and cultural geography to a new range of questions and debate. In the course of the thesis, it is maintained that you cannot consider Sauer and culture in the “field” of geography without remobilising him as geographer amidst culture in the “field”; nor can you consider Sauer as fieldworker in isolation from the “passage to premodernity” of his life and work. Sauer is thus positioned ambivalently in various “moments” of the practices and politics of dwelling and travelling in the “field” and presented as an ant imodernist looking for a cultural and an academic “home”.

description: The thesis " Linguistic and semiotic practices on Instagram: Focusing on a sample of students from the Department of Journalism and Mass Media Communication” of Aristotle University examined the language and images (photos or posts and quotations etc.) used by the students of our Department on a new social media called Instagram (2010). Among the fifteen personal profiles of students, I chose and studied specifically five personal profiles on Instagram as a sample group for the analysis that had, over a period of three months, greater movement and usage in this social means, the highest number of posts in general, as well as the highest frequency of posts that included combinations of text and image. The five personal profiles of the students had been studied with regards to: firstly, the most typical linguistic phenomena that exhibit, for example the orality, the conversational style, the Latin-greek, Greek-latin text, the use of the English language and code switching(Greek / English); and, secondly, their images, focusing on how their visual meanings stated. Finally, through this study, conclusions were drawn for the individual /social identities that future journalists construct/display, taking advantage of the technical possibilities and peculiarities of Instagram, a media which promotes capturing of important moments / events of everyday life.

description: We tackle the problem of discovering novel classes in an image collection given labelled examples of other classes. We present a new approach called AutoNovel to address this problem by combining three ideas: (1) we suggest that the common approach of bootstrapping an image representation using the labelled data only introduces an unwanted bias, and that this can be avoided by using self-supervised learning to train the representation from scratch on the union of labelled and unlabelled data; (2) we use ranking statistics to transfer the model's knowledge of the labelled classes to the problem of clustering the unlabelled images; and, (3) we train the data representation by optimizing a joint objective function on the labelled and unlabelled subsets of the data, improving both the supervised classification of the labelled data, and the clustering of the unlabelled data. Moreover, we propose a method to estimate the number of classes for the case where the number of new categories is not known a priori. We evaluate AutoNovel on standard classification benchmarks and substantially outperform current methods for novel category discovery. In addition, we also show that AutoNovel can be used for fully unsupervised image clustering, achieving promising results.

description: A one-way quantum key distribution scheme based on intrinsically stable Faraday-mirror type Michelson interferometers with four-port polarizing beampslitters has been demonstrated which can compensate for birefringence effects automatically. The encoding is performed with phase modulators, but decoding is accomplished through measurement of the polarization state of Bob's photons. An extinction ratio of about 30dB was maintained for several hours over 50km of fiber at 1310nm without any adjustment to the setup, which shows its good potential for practical systems

description: In this paper, we study a projectable Hořava-Lifshitz cosmology without the detailed balance condition minimally coupled to a non-linear self-coupling scalar field. In the minisuperspace framework, the super Hamiltonian of the presented model is constructed by means of which, some classical solutions for scale factor and scalar field are obtained. Since these solutions exhibit various types of singularities, we came up with the quantization of the model in the context of the Wheeler-DeWitt approach of quantum cosmology. The resulting quantum wave functions are then used to investigate the possibility of the avoidance of classical singularities due to quantum effects which show themselves important near these singularities.

description: We propose a stochastic particle model in (1+1)-dimensions, with one dimension corresponding to rapidity and the other one to the transverse size of a dipole in QCD, which mimics high-energy evolution and scattering in QCD in the presence of both saturation and particle-number fluctuations, and hence of Pomeron loops. The model evolves via non-linear particle splitting, with a non-local splitting rate which is constrained by boost-invariance and multiple scattering. The splitting rate saturates at high density, so like the gluon emission rate in the JIMWLK evolution. In the mean field approximation obtained by ignoring fluctuations, the model exhibits the hallmarks of the BK equation, namely a BFKL-like evolution at low density, the formation of a traveling wave, and geometric scaling. In the full evolution including fluctuations, the geometric scaling is washed out at high energy and replaced by diffusive scaling. It is likely that the model belongs to the universality class of the reaction-diffusion process. The analysis of the model sheds new light on the Pomeron loops equations in QCD and their possible improvements.

description: (abridged) Photometry and long-slit spectroscopy are presented for a sample of 6 galaxies with a low surface brightness stellar disc and a bulge. The stellar and ionised-gas kinematics were measured along the major and minor axis in half of the sample galaxies, whereas the other half was observed only along two diagonal axes. Spectra along two diagonal axes were obtained also for one of the objects with major and minor axis spectra. The kinematic measurements extend in the disc region out to a surface-brightness level mu_R~24mag/arcsec^2 reaching in all cases the flat part of the rotation curve. The stellar kinematics turns out to be more regular and symmetric than the ionised-gas kinematics, which often shows the presence of non-circular, off-plane, and non-ordered motions. This raises the question about the reliability of the use of the ionised gas as the tracer of the circular velocity in the modeling of the mass distribution, in particular in the central regions of low surface brightness galaxies.

description: In this work we present a dual-mode mid-infrared workflow [6], for detecting sub-superficial mural damages in frescoes artworks. Due to the large nature of frescoes, multiple thermal images are recorded. Thus, the experimental setup may introduce measurements errors, seen as inter-frame changes in the image contrast, after mosaicking. An approach to lowering errors is to post-process the mosaic [10] via osmosis partial differential equation (PDE) [12, 13], which preserves details, mass and balance the lights: efficient numerical study for osmosis on large images is proposed [2, 11], based on operator splitting [8]. Our range of Cultural Heritage applications include the detection of sub-superficial voids in Monocromo (L. Da Vinci, Castello Sforzesco, Milan) [5], the light-balance for multi-spectral imaging and the data integration on the Archimedes Palimpsest [10].

description: We present five recycled pulsars discovered during a 21-cm survey of approximately 4,150 deg^2 between 15 deg and 30 deg from the galactic plane using the Parkes radio telescope. One new pulsar, PSR J1528-3146, has a 61 ms spin period and a massive white dwarf companion. Like many recycled pulsars with heavy companions, the orbital eccentricity is relatively high (~0.0002), consistent with evolutionary models that predict less time for circularization. The four remaining pulsars have short spin periods (3 ms < P < 6 ms); three of these have probable white dwarf binary companions and one (PSR J2010-1323) is isolated. PSR J1600-3053 is relatively bright for its dispersion measure of 52.3 pc cm^-3 and promises good timing precision thanks to an intrinsically narrow feature in its pulse profile, resolvable through coherent dedispersion. In this survey, the recycled pulsar discovery rate was one per four days of telescope time or one per 600 deg^2 of sky. The variability of these sources implies that there are more millisecond pulsars that might be found by repeating this survey.

Liu Yü-hsi (772-842) : a study of his thought
Creators: name: Wong, Kwok-Yiu

Year: 2009

description: This thesis examines the thought of Liu Yü-hsi (772-842), a participant of the mid-T’ang (Ca. 750-850) Confucian revival movement. In this study, I have attempted to construct an approximation of Liu’s thought through the discussions of two major elements in his thought: Confucianism and Buddhism. In addition, I also discuss his famous philosophical dissertation T’ien Lun” (“On Heaven”) in order to present a basic understanding of Liu’s world view. These discussions reveal that Confucianism occupied a central position in Liu YU-hsi’s thought. His major concern in life was how to “bring benefit to the people” (“chi-wu”). Buddhism, while it occupied an important place in Liu’s life, never took charge of his inner life completely. He conceived that Buddhism and Confucianism share a similar goal in their teachings. In particular, Buddhism should form a complement to Confucianism. Hence, he selected elements from various Buddhist schools that best fit his major concern in life. In this way, Buddhism and Confucianism co-exist in a harmonious and connected fashion in his thought. To achieve the goal of “chi-wu,” Liu also believed that humans are totally responsible for their own future. The phenomenal world, according to Liu, is regulated by a pair of concepts -- shu (numerical dimensions) and shih (conditions). These concepts explain the basic principles behind which events occur in the world. If human beings are to optimize the state of their existence, they have to exert themselves to construct a well-regulated society. Such a society can be achieved by the use of laws that are based on Confucian moral values. Therefore, Liu’s thought can be characterized by his social concern.

description: We investigate the low-energy effective description of non-geometric compactifications constructed by T-dualizing two or three of the directions of a T^3 with non-vanishing H-flux. Our approach is to introduce a D3-brane in these geometries and to take an appropriate decoupling limit. In the case of two T-dualities, we find at low energies a non-commutative T^2 fibered non-trivially over an S^1. In the UV this theory is still decoupled from gravity, but is dual to a little string theory with flavor. For the case of three T-dualities, we do not find a sensible decoupling limit, casting doubt on this geometry as a low-energy effective notion in critical string theory. However, by studying a topological toy model in this background, we find a non-associative geometry similar to one found by Bouwknegt, Hannabuss, and Mathai.

description: Η παρούσα διπλωματική εργασία αναφέρεται στο πεδίο των ασυρμάτων ad-hoc δικτύων και έχει ως στόχο τη σύγκριση του πρωτοκόλλου MAC του προτύπου 802.11 με ένα πρωτόκολλο MAC, το οποίο βασίζεται στον έλεγχο ισχύος. Τα εκτεθειμένα τερματικά παίζουν καθοριστικό ρόλο στην απόδοση ενός ασυρμάτου ad hoc δικτύου. Το 802.11 MAC πρωτόκολλο δεν εισάγει μεθόδους για την μείωση του πλήθους των τερματικών που εκτίθενται στην μετάδοση των CTS μηνυμάτων από τον δέκτη. Στην παρούσα εργασία, το MAC πρωτόκολλο που μελετάμε, κάνει χρήση των μηχανισμών ελέγχου ισχύος, κι έτσι, μειώνεται η ποσότητα των εν λόγω τερματικών. Έτσι λοιπόν, αξιοποιείται καλύτερα το διαθέσιμο εύρος ζώνης, αυξάνοντας την πιθανότητα για παράλληλες μεταδόσεις, σε περιπτώσεις όπου το 802.11 MAC πρωτόκολλο επιτρέπει να γίνει μια μετάδοση τη φορά. Για τον σκοπό της σύγκρισης αυτών των δύο πρωτοκόλλων αναπτύχθηκαν προσομοιώσεις, στον προσομοιωτή δικτύων Network Simulator 2, σε διάφορες τοπολογίες δικτύων, ώστε να έχουμε μια συνολική εικόνα για τις σχέσεις Offered Load , Throughput και Total Delay, του κάθε πρωτοκόλλου.
description: This thesis refers to the field of wireless ad-hoc networks and aims to compare the MAC protocol of 802.11 standard with a MAC protocol which is based on the method of power capturing. Exposed terminals play a crucial role in the throughput of a wireless ad-hoc network. The 802.11 MAC protocol introduces no methods for decreasing the amount of the terminals exposed to the transmission of the CTS message by the receiver. In this thesis, the MAC protocol, using power capturing mechanisms, decreases the amount of such terminals. This allows for the better utilization of the available bandwidth via increasing the chances for parallel transmissions in situations where the MAC protocol of the 802.11 standard would allow for only one transmission to occur at a time. For the comparison of these two protocols developed simulations in Network Simulator 2, on different network topologies, to acquire a complete view of the relation between Offered Load, Throughput and Total Delay of each protocol.

description: Recently, Vedral and one of us proposed an entanglement-based witness of non-classicality in systems that need not obey quantum theory, based on constructor-information-theoretic ideas, which offers a robust foundation for recently proposed table-top tests of non-classicality in gravity. The witness asserts that if a mediator can entangle locally two quantum systems, then it has to be non-classical. Hall and Reginatto claimed that there are classical systems that can entangle two quantum systems, thus violating our proposed witness. Here we refute that claim, explaining that the counterexample proposed by Hall and Reginatto in fact validates the witness, vindicating the witness of non-classicality in its full generality.

description: The series-series compensation topology is widely adopted in many wireless power transfer applications. For such systems, their wireless power receiver part typically involves a DC-DC converter with front-stage full-bridge diode rectifier, to process the high-frequency transmitted AC power into a DC output voltage for the load. It is recently reported that the current source nature of the series-series compensation will introduce right-half-plane (RHP) zeros into the small-signal transfer functions of the DC-DC converter of the wireless power receiver, which will severely affect the stability and dynamic response of the system. To resolve this issue, in this paper, it is proposed to adopt a different rectifier configuration for the system such that the input current to the DC-DC converter becomes controllable to eliminate the presence of RHP zeros of the small-signal transfer functions of the system. This rectifier can be applied to different wireless power receivers using the buck, buck-boost, or boost converters. As compared with the original wireless power receivers, the modified ones feature minimum-phase characteristics and hence ease the design of compensator. Theoretical and experimental results are provided. The comparative experimental results verify the elimination of the RHP zero, improved dynamic responses of reference tracking and against load disturbances, and a larger stability margin.

description: Between mirrors, the density of electromagnetic modes differs from the one in free space. This changes the radiation properties of an atom as well as the light forces acting on an atom. It has profound consequences in the strong-coupling regime of cavity quantum electrodynamics. For a single atom trapped inside the cavity, we investigate the atom-cavity system by scanning the frequency of a probe laser for various atom-cavity detunings. The avoided crossing between atom and cavity resonance is visible in the transmission of the cavity. It is also visible in the loss rate of the atom from the intracavity dipole trap. On the normal-mode resonances, the dominant contribution to the loss rate originates from dipole-force fluctuations which are dramatically enhanced in the cavity. This conclusion is supported by Monte-Carlo simulations.

description: We present a self-similar solution to describe the propagation of a shock wave whose energy is deposited or lost at the front. Both of the propagation of the shock wave in a medium having a power-law density profile and the expansion of the medium to a vacuum after the shock breakout are described with a Lagrangian coordinate. The Chapman-Jouguet detonation is found to accelerate the medium most effectively. The results are compared with some numerical simulations in the literature. We derive the fractions of the deposited/lost energy at the shock front in some specific cases, which will be useful when applying this solution to actual phenomena.

description: Αντικείμενο της παρούσας μελέτης είναι η νομική προστασία των βάσεων δεδομένων στο εγχώριο δίκαιο, όπως αυτή διαμορφώθηκε μετά την ενσωμάτωση της κοινοτικής Οδηγίας 96/9/ΕΟΚ. Το πρώτο μέρος είναι αφιερωμένο στην οριοθέτηση της έννοιας «βάση δεδομένων». Παρουσιάζεται το νομικό πλαίσιο που διέπει τις βάσεις δεδομένων, επιχειρείται μια σύντομη ανάλυση των στοιχείων που συνθέτουν τον ορισμό της έννοιας καθώς και μια συγκριτική παρουσίαση κάποιων προϊόντων που εμφανίζουν ομοιότητες με τις βάσεις δεδομένων. Το δεύτερο κεφάλαιο της μελέτης πραγματεύεται την προστασία των βάσεων δεδομένων μέσα από τις διατάξεις του δικαίου πνευματικής ιδιοκτησίας. Έμφαση δίνεται στα νέα δεδομένα που καθιέρωσε ο κοινοτικός νομοθέτης ως προς κριτήριο της πρωτοτυπίας. Στη συνέχεια, οριοθετείται το δικαίωμα του δημιουργού της βάσης δεδομένων, αναλύεται το περιεχόμενο του δικαιώματος και οι περιορισμοί του. Τέλος, το τρίτο κεφάλαιο επικεντρώνεται στην προστασία της βάσης δεδομένων με βάση το νέο δικαίωμα ειδικής φύσης που καθιέρωσε η Οδηγία 96/9 και το οποίο φέρει πλέον το κύριο βάρος της προστασίας των πληροφοριακών συνόλων. Εξετάζεται η νομική φύση του καινοφανούς αυτού δικαιώματος, οι προϋποθέσεις χορήγησής του, καθώς και το περιεχόμενο αλλά και οι περιορισμοί του. Ειδική αναφορά γίνεται στην ανάλυση και ερμηνεία των αόριστων εννοιών που συνθέτουν το νέο δικαίωμα από την νομολογία του Δικαστηρίου της Ευρωπαϊκής Ένωσης.
description: The aim of this study is to examine the legal protection of databases in domestic law, as it stands after the incorporation of EU Directive 96/9/EC. The first part is devoted to the definition of the term 'database'. We present the legal framework for databases and we attempt a brief analysis of the components of the definition as well as a comparative presentation of certain products that appear similar to the databases. The second chapter of the study deals with the protection of databases through the provisions of copyright law. Emphasis is placed on new data established by the Community legislature as to the criterion of originality. Furthermore, we delineate the copyright of databases and we analyze the content of the right and also its limitations. Finally, the third chapter focuses on database protection on the basis of the new sui generis right introduced by the Directive 96/9, which now bears the brunt of the protection of information sets. We examine the legal nature of this novel right, the conditions for granting, as well as the its content and limitations. Specific reference is made to the analysis and interpretation of the vague concepts that make up the new right from the jurisprudence of the European Court of Justice.

description: We present new results on the statistical hadronization of heavy quarks at SPS, RHIC and LHC energies. Several new aspects are considered, among them a separation of the collision geometry into a ``core'' and a ``corona'' part and an estimate of the annihilation rate of charm quark in a hot plasma, together with a critical assessment of its influence on the results. For RHIC energies we investigate the centrality dependence of J/psi production focusing on the model results for different values of the charm production cross section, including its theoretical and experimental uncertainty. We also study, within this model, the rapidity dependence of the J/psi yield. Recent RHIC data from the PHENIX experiment are well reproduced. At LHC energy, we update our model predictions for the centrality dependence of the J/psi yield and investigate as well the rapidity dependence. We also discuss the transverse momentum distributions of J/psi mesons expected from the model and provide predictions for a range of values of the expansion velocity at chemical freeze-out. Finally, we extend the model to predict Upsilon yields in Pb+Pb collisions at LHC energy.

title: Statistical Methods to Address Selection Bias in Economic Evaluations that Use Patient-Level Observational Data
Creators: name: Kreif, N
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2013

description: This thesis compares statistical methods for addressing selection bias in cost-effectiveness analyses (CEA) that use observational data. The thesis has four objectives: (1) to critically appraise currently recommended statistical methods, (2) to consider alternative statistical methods for CEA, (3) to compare propensity score (PS) approaches and Genetic Matching (GM) for estimating subgroup-effects in CEA, and (4) to compare methods that combine regression with PS approaches, for CEA. I developed a new checklist for critically appraising statistical methods for addressing selection bias in CEA, and applied it in a systematic review of published CEA. Most studies used regression or matching methods, and did not assess their underlying assumptions, such as the correct specification of the PS or the endpoint regression model. I identified methods that can make less restrictive assumptions: GM, a multivariate matching method that can directly balance covariates, double-robust (DR) methods, regression-adjusted matching, and machine learning estimation of the PS and the endpoint regression. I compared these methods across a range of typical CEA circumstances, using simulations and case studies. In the first case study, where cost-effectiveness estimates for subgroups were of interest, I found that the cost-effectiveness results differed according to the statistical approach. The accompanying simulation study found that GM was relatively robust to the misspecification of the PS, and provided the least biased and most precise estimates of cost-effectiveness for each subgroup. The second simulation study considered DR methods and regression-adjusted matching for estimating overall cost-effectiveness and found that regression-adjusted matching was relatively robust to misspecification of the PS and the regression model. The third study extended these approaches with machine learning estimation of the PS and the endpoint regression, and found that bias due to misspecification could be further reduced. This thesis concludes that those approaches that relax the assumption that the statistical model for addressing selection bias is correctly specified, can give more accurate and precise estimates of cost-effectiveness than previously recommended methods. Findings from this thesis can improve the quality of CEA that use patient-level observational data, to help future studies provide a sounder basis for policy making.
Phase transitions in social sciences: two-populations mean field theory

description: A new mean field statistical mechanics model of two interacting groups of spins is introduced and the phase transition studied in terms of their relative size. A jump of the average magnetization is found for large values of the mutual interaction when the relative percentage of the two populations crosses a critical threshold. It is shown how the critical percentage depends on internal interactions and on the initial magnetizations. The model is interpreted as a prototype of resident-immigrant cultural interaction and conclusions from the social sciences perspectives are drawn.

description: We introduce a new method to estimate the probability that an extragalactic transient source is associated with a candidate host galaxy. This approach relies solely on simple observables: sky coordinates and their uncertainties, galaxy fluxes and angular sizes. The formalism invokes Bayes' rule to calculate the posterior probability P(O_i|x) from the galaxy prior P(O), observables x, and an assumed model for the true distribution of transients in/around their host galaxies. Using simulated transients placed in the well-studied COSMOS field, we consider several agnostic and physically motivated priors and offset distributions to explore the method sensitivity. We then apply the methodology to the set of 13~fast radio bursts (FRBs) localized with an uncertainty of several arcseconds. Our methodology finds nine of these are securely associated to a single host galaxy, P(O_i|x)>0.95. We examine the observed and intrinsic properties of these secure FRB hosts, recovering similar distributions as previous works. Furthermore, we find a strong correlation between the apparent magnitude of the securely identified host galaxies and the estimated cosmic dispersion measures of the corresponding FRBs, which results from the Macquart relation. Future work with FRBs will leverage this relation and other measures from the secure hosts as priors for future associations. The methodology is generic to transient type, localization error, and image quality. We encourage its application to other transients where host galaxy associations are critical to the science, e.g. gravitational wave events, gamma-ray bursts, and supernovae. We have encoded the technique in Python on GitHub: https://github.com/FRBs/astropath.

Empowerment of Chinese (English as a second language) youth through popular theatre
Creators: name: Lam, Angelo
Publisher: name: University of British Columbia
Year: 2009

description: This study examines theories of delinquency and the history Of the Chinese community in Vancouver in recognition of the fact that they are important to the development and establishment of effective programs for Chinese ESL (english as a second language) youth. Without a clear understanding of how we have arrived at the current situation in youth work, it is difficult to separate the symptoms from the problems as they pertain to Chinese ESL youth. Existing programs focus on approaches to “integrate” and “incorporate” youth into Canadian society, yet it is not always clear if the goals of “integration” and “incorporation” are a help or hinderance to Chinese ESL youth. Programs targeted at “transformation”, such as popular theatre, may be more effective since they deal with problems at a socio-political and historical level. Such an approach also deal with the concept of power and analyzes the “covert institutional violence” that exists in society and strives for long-term changes at a structural level. The hypothesis put forward in this study is that a popular theatre program would have a positive effect on the self-esteem of Chinese ESL youth. The research uses a pre-test - post-test design. One group of 15 participants from a single Vancouver high-school was referred to the popular theatre program by school personnel. The Culture Free Self-Esteem Inventory was administered at the beginning and the end of the program to provide quantitative data on the change in self-esteem level of participants. Interviews with 3 of the participants were conducted and transcribed to provide qualitative data. It was found that the change in general, social and overall self-esteem was significant at the 0.005 level while other self-esteem sub-categories did not show a statistical significance at the 0.10 level. Analysis of the qualitative data obtained from the interviews identified 3 themes in the responses given by the interviewees concerning the popular theatre program: a) opportunities for expression; b) shared life experiences; and c) learning new ideas in order to take action. The results were consistent with the quantitative data as well as the ideas and techniques of popular theatre. The results suggest that programs targeted at “transformation” are effective at raising the self-esteem level of Chinese ESL youth.
