The QUEST RR Lyrae Survey II: The Halo Overdensities in the First Catalog

description: The first catalog of the RR Lyrae stars (RRLS) in the Galactic halo by the QUEST Survey has been searched for significant overdensities that may be debris from disrupted dwarf galaxies or globular clusters. Away from the major overdensities, the distribution of these stars is adequately fit by a smooth halo model, in which the flattening of the halo decreases with increasing galactocentric distance (Preston et al 1991). This model was used to estimate the ``background'' of RRLS on which the halo overdensities are overlaid. A procedure was developed for recognizing groups of stars that constitute significant overdensities with respect to this background. To test this procedure, a Monte Carlo routine was used to make artificial RRLS surveys that follow the smooth halo model, but with Poisson distributed noise in the numbers of RRLS and, within limits, random variations in the positions and magnitudes of the artificial stars. The artificial surveys created by this routine were examined for significant groups in exactly the same way as the QUEST survey. These calculations provided estimates of the frequencies with which random fluctuations produce significant groups. In the QUEST survey, there are six significant overdensities that contain six or more stars and several smaller ones. The small ones and possibly one or two of the larger ones may be artifacts of statistical fluctuations, and they need to be confirmed by measurements of radial velocity and/or proper motion. The most prominent groups are the northern stream from the Sagittarius dwarf spheroidal galaxy and a large group in Virgo. Two other groups lie in the direction of the Monoceros stream and at approximately the right distance for membership. Another group is related to the globular cluster Palomar 5.

Prometheus unbound : towards the more precise proscription of the socially undesirable market conduct associated with dominance
Creators: name: Colvin, Craig Grierson
Publisher: name: University of British Columbia
Year: 2008

description: The regulation of the market conduct of dominant firms is an entrenched part of the competition laws in many jurisdictions. The conduct which such laws proscribe has been variously described as "abuse of dominance", "anticompetitive conduct", "monopolization" or "improper use of market power". Each description is used by way of contrast to "normal competitive conduct". In all jurisdictions the courts have experienced considerable difficulty in articulating the distinction between lawful competitive behaviour and unlawful market rivalry, principally because both may exclude rivals and lead to concentrated markets, and the same conduct may be competitive or anticompetitive depending upon context. We argue, based upon an understanding of competition as a dynamic process (a cycle of innovation and imitation), driven by rivalry between firms in which the possibility of achieving dominance is a necessary element of the dynamic, that there is no market conduct unique to dominant firms that is socially undesirable. Rather, the prospect of dominance motivates all firms to pursue either competitive or rent seeking strategies to secure the supra-normal profits attendant to a dominant position. Competitive strategies are socially desirable as they seek to meet (or influence) consumer needs and thereby promote total welfare. Rent seeking strategies are undesirable as their purpose is to prevent other firms from meeting (or influencing) consumer needs and thus represent investments in the distribution rather than the creation of wealth. We propose the rejection of existing laws, which require proof of dominance, and their replacement by a law which proscribes rent seeking by all firms. We contend that such a law would articulate with greater precision the distinction between desirable competitive behaviour and unlawful rivalry providing the courts with improved direction as to the evidentiary enquiry to be undertaken when a complaint of anticompetitive conduct is made. It would also relieve dominant firms from the vagaries of the uncertainties inherent in the existing approach to the regulation of market conduct associated with dominance.

description: Changes in the modern business environment are rapid and competition between businesses is increasing constantly. Businesses need to be flexible and they have to adapt quickly to these changes in order to survive and make a profit. In addition, customer requirements are multiplying, leading businesses to seek more solutions to serve them more effectively. In the past few decades, businesses have realized that flexibility is driven by the efficient supply chain performance. The purpose of the supply chain is to coordinate all its members in order for the product to reach the final consumer. This can only be achieved with proper management. The need for effective supply chain management emanated from the fact that there is a great deal of interdependence among companies, as far as their cooperation is concerned. The effective management of the supply chain is also reinforced by information systems, which are the core of business. Information systems, along with the basic principles of supply chain management, can provide the business with an edge over competition. The purpose of the current dissertation is to highlight the contribution of information systems to the efficient management of the supply chain.

description: Quantum properties, such as entanglement and coherence, are indispensable resources in various quantum information processing tasks. However, there still lacks an efficient and scalable way to detecting these useful features, especially for high-dimensional and multipartite quantum systems. In this work, we exploit the convexity of samples without the desired quantum features and design an unsupervised machine learning method to detect the presence of such features as anomalies. Particularly, in the context of entanglement detection, we propose a complex-valued neural network composed of pseudo-siamese network and generative adversarial net, and then train it with only separable states to construct non-linear witnesses for entanglement. It is shown via numerical examples, ranging from two-qubit to ten-qubit systems, that our network is able to achieve high detection accuracy which is above 97.5% on average.Moreover, it is capable of revealing rich structures of entanglement, such as partial entanglement among subsystems. Our results are readily applicable to the detection of other quantum resources such as Bell nonlocality and steerability, and thus our work could provide a powerful tool to extract quantum features hidden in multipartite quantum data.

description: In the present study, the possibility of enhancing the diagnostic potential of the FTIR technique for the study of the autoxidation of virgin olive oil was examined, by applying the method of generalized two-dimensional spectra correlation (g2D-COR) and its expansion the removable window (MW-2D-COR). The research included a preliminary test applied to a set of time series obtained from the storage of the same sample in repetitions. Among others, one of the aims was to examine whether the derived information was repeatable. The main study focused on the examination of a group of virgin olive oils stored at room temperature for 12 months with periodic sampling every 2 months. For comparison purposes, non-chemometric and chemometric approaches proposed in the literature were also examined. The findings showed advantages and some weak points of the methodology that need further investigation for the better evaluation of g2D IR-COS and MW-2D-COS as tools for virgin olive oil quality control under mild storage conditions in the dark.

description: Quantum technology is an emergent and potentially disruptive discipline, with the ability to affect many human activities. Quantum technologies are dual-use technologies, and as such are of interest to the defence and security industry and military and governmental actors. This report reviews and maps the possible quantum technology military applications, serving as an entry point for international peace and security assessment, ethics research, military and governmental policy, strategy and decision making. Quantum technologies for military applications introduce new capabilities, improving effectiveness and increasing precision, thus leading to `quantum warfare', wherein new military strategies, doctrines, policies and ethics should be established. This report provides a basic overview of quantum technologies under development, also estimating the expected time scale of delivery or the utilisation impact. Particular military applications of quantum technology are described for various warfare domains (e.g. land, air, space, electronic, cyber and underwater warfare and ISTAR -- intelligence, surveillance, target acquisition and reconnaissance), and related issues and challenges are articulated.

Mass Modelling with Minimum Kinematic Information

Publisher: name: arXiv
Year: 2007

subject: FOS: Physical sciences

description: Mass modelling of early-type systems is a thorny issue. In this paper, we present a new mass modelling formalism for ellipticals that invokes no observations other than the central velocity dispersion ($σ_0$) and photometry. The essence of the method lies in choosing a local mass-to-light ratio ($M/L$) profile for a galaxy, with which the deprojected luminosity density distribution (along the major axis coordinate $x$) is scaled. The resulting discontinuous mass density profile is then smoothed, according to a laid out prescription; the local $M/L$ profile that stems from this smoothed mass density, is found to be significantly different from the raw $M/L$ distribution. A suite of model galaxies (both Sersic and cored in nature) is used for extensive experimentation in order to characterise this raw $M/L$ profile and in each case, the mass density recovered from this mass modelling technique is compared to the known mass distribution. We opt to work with a raw $M/L$ profile that is a simple two-stepped function of $x$, with a low inner and higher outer value of $M/L-Υ_{in}$ and $Υ_{out}$, respectively. The only constraint that we have on this profile is in the centre of the galaxy, via $σ_0$. This value of $σ_0$ is implemented in the virial theorem to obtain an estimate of the central $M/L$ ratio of the galaxy. The fallibility of the virial mass estimate is taken care of, by allowing for a range in the values of $Υ_{in}$ that can be used for a given galaxy model. Moreover, our experiments indicate that $Υ_{out}$ is uniquely known, for a given $Υ_{in}$; for cored galaxies, this functional form is found uniquely dependant on the core radius. The jump radius of the raw $M/L$ profile is chosen to be thrice the effective radius of the galaxy.

description: The second order Ordinary Differential Equation which describes the unknown part of the solution space of some vacuum Bianchi Cosmologies is completely integrated for Type III, thus obtaining the general solution to Einstein's Field Equations for this case, with the aid of the sixth Painlevé transcendent $P_{VI}$. For particular representations of $P_{VI}$ we obtain the known Kinnersley two-parameter space-time and a solution of Euclidean signature. The imposition of the space-time generalization of a "hidden" symmetry of the generic Type III spatial slice, enables us to retrieve the two-parameter subfamily without considering the Painlevé transcendent.

description: Using the Global Magneto-Ionic Medium Survey (GMIMS) Low-Band South (LBS) southern sky polarization survey, covering 300 to 480 MHz at 81 arcmin resolution, we reveal the brightest region in the Southern polarized sky at these frequencies. The region, G150-50, covers nearly 20deg$^2$, near (l,b)~(150 deg,-50 deg). Using GMIMS-LBS and complementary data at higher frequencies (~0.6--30 GHz), we apply Faraday tomography and Stokes QU-fitting techniques. We find that the magnetic field associated with G150-50 is both coherent and primarily in the plane of the sky, and indications that the region is associated with Radio Loop II. The Faraday depth spectra across G150-50 are broad and contain a large-scale spatial gradient. We model the magnetic field in the region as an expanding shell, and we can reproduce both the observed Faraday rotation and the synchrotron emission in the GMIMS-LBS band. Using QU-fitting, we find that the Faraday spectra are produced by several Faraday dispersive sources along the line-of-sight. Alternatively, polarization horizon effects that we cannot model are adding complexity to the high-frequency polarized spectra. The magnetic field structure of Loop II dominates a large fraction of the sky, and studies of the large-scale polarized sky will need to account for this object. Studies of G150-50 with high angular resolution could mitigate polarization horizon effects, and clarify the nature of G150-50.

Συγκρίνει την εβραϊκή αγωγή με την αγωγή των παιδιών στην αρχαία Ελλάδα και διαπιστώνει σημαντικές ομοι¬ότητες αλλά και διαφορές.

Ωστόσο οι Παροιμίες ως βιβλικό κείμενο, σε αντίθεση με τον αρχαιοελληνικό φιλοσοφικό στοχασμό που αναζητά να ανακαλύψει τον Θεό, προϋποθέτει την αποκάλυψη του Θεού και την πίστη σε Αυτόν.Παρόλες τις διαφορές που εντοπίζονται η ανάγκη διάπλασης ενός ενάρετου και ηθικού χαρα¬κτήρα είναι μια οικουμενική και πανανθρώπινη ανάγκη που αφορά όλους τους λαούς και τις κοινωνίες κάθε εποχής
description: This dissertation examines ethical teaching and more specifically the importance of the virtues of wisdom, prudence and justice both in the book of Proverbs and in the ancient Greek philosophy. It compares the Jewish education with the education of the eastern peoples and especially with the education received by the children in ancient Greece and finds significant similarities and differences. The dominant idea that pervades the entire book of Proverbs is that the truly wise man is the one who fears the Lord. Wisdom, personified, talks with her children which they respond to this dialogue by listening to her advice or trying to acquire and keep it, in order to gain justice, kindness of spirit, purity of heart, morality, modesty and generally all that can make a person happy with himself and create a balanced community. On the other hand, the nature and accumulation of the virtues of wisdom, prudence and justice preoccupied sophists, orators and philosophers such as Socrates, Plato and Aristotle. However, the Proverbs as a biblical text, in contrast to the ancient Greek philosophical thought that seeks to discover God, presupposes the revelation of God and faith in Him. Despite the differences, the need to create a virtuous and moral character is a universal need that concerns all peoples and societies of every age

description: The present paper is devoted to construction of an optimal quadrature formula for approximation of Fourier integrals in the Hilbert space $W_2^{(1,0)}[a,b]$ of non-periodic, complex valued functions. Here the quadrature sum consists of linear combination of the given function values on uniform grid. The difference between integral and quadrature sum is estimated by the norm of the error functional. The optimal quadrature formula is obtained by minimizing the norm of the error functional with respect to coefficients. In addition, analytic formulas for optimal coefficients are obtained using the discrete analogue of the differential operator $d^2/d x^2-1$. Further, the order of convergence of the optimal quadrature formula is studied.

Inter-American human rights protection: how methods and rules of interpretation are framed
Creators: name: Reindel, Florian
Publisher: name: University of British Columbia
Year: 2008

description: This thesis is an analytical study of the rules and methods in the respective cultural context used in the interpretation of human rights treaties. It involves an examination of the interpretation methods and rules of "ordinary" international treaties, which are being compared with those of the interpretation methods and rules of human rights treaties. The Inter-American human rights protection system with the judgements of the Inter-American Court of Human Rights and the decisions of the Inter-American Commission on Human Rights serve as an example. This thesis also includes a comparative overview of the various international and regional human rights protection mechanisms. Human rights treaties have a special nature when being compared to other international treaties. They are concluded by states which limit their sovereignty for an indefinite period of time, while granting rights to individuals, who are not partners of the treaty. Through a process of evolution those treaties are not interpreted in the classic objective or subjective method ofinterpretation, but in a newly developed dynamic approach. That is, the meaning of the text is looked at under the intention of the treaty, however, under present day conditions. All codified and non-codified rules of treaty interpretation are applied, however, under the limitation that the rights of the individual are being protected.

Eshelby, Proc. Roy. Soc. A241, 376 (1957)), one can calculate the saddle point energy of such a structural rearrangement. The neighbourhood of the saddle point gives rise to soft resonant vibrational modes. One can calculate their density, their kinetic energy, their fourth order potential term and their coupling to longitudinal and transverse sound waves.

description: Near equilibrium, Green-Kubo relations provide microscopic expressions for macroscopic transport coefficients in terms of equilibrium correlation functions. At their core, they are based on the intimate relationship between response and fluctuations as embodied by the equilibrium fluctuation-dissipation theorem, a connection generically broken far from equilibrium. In this work, we identify a class of perturbations whose response around far-from-equilibrium steady states is linked to steady-state correlation functions via an equilibrium-like fluctuation-response equality. We then utilize this prediction to substantiate linearized hydrodynamic transport equations that describe how spatial inhomogeneities in macroscopic nonequilibrium systems relax. As a consequence, we derive nonequilibrium Green-Kubo relations for the transport coefficients of two types of hydrodynamic variables: local conserved densities and broken-symmetry modes. A byproduct of this work is to provide a theoretical foundation for the validity of Onsager's regression hypothesis around nonequilibrium steady states. Our predictions are analytically and numerically corroborated for two model systems: density diffusion in a fluid of soft, spherical active Brownian particles and phase diffusion in the noisy Kuramoto model on a square lattice.

description: A partial submillimeter line-survey was performed toward 7 high-mass young stellar objects (YSOs) aimed at detecting H2CO, CH3OH, CH2CO, CH3CHO, C2H5OH, HCOOH, HNCO and NH2CHO. In addition, other organic species such as CH3CN have been observed. The aim is to establish the chemical origin of a set of complex organic molecules thought to be produced by grain surface chemistry in high mass YSOs. Rotation temperatures and beam-averaged column densities are determined. Based on their rotation diagrams, molecules can be classified as either cold (<100 K) or hot (>100 K). This implies that complex organics are present in at least two distinct regions. Furthermore, the abundances of the hot oxygen-bearing species are correlated, as are those of HNCO and NH2CHO. This is suggestive of chemical relationships within, but not between, those two groups of molecules. The most likely explanation for the observed correlations of the various hot molecules is that they are ``first generation'' species that originate from solid-state chemistry. This includes H2CO, CH3OH, C2H5OH, HCOOCH3, CH3OCH3, HNCO, NH2CHO, and possibly CH3CN, and C2H5CN. The correlations between sources implies very similar conditions during their formation or very similar doses of energetic processing. Cold species such as CH2CO, CH3CHO, and HCOOH, some of which are seen as ices along the same lines of sight, are probably formed in the solid state as well, but appear to be destroyed at higher temperatures. A low level of non-thermal desorption by cosmic rays can explain their low rotation temperatures and relatively low abundances in the gas phase compared to the solid state. The CH3CCH abundances can be fully explained by low temperature gas phase chemistry. No cold N-containing molecules are found.

description: 20 years have now passed since the democratic revolutions of Latin America, East Asia, and Eastern Europe. In most cases, the transition has been sustained, with only a small number of reversions from democratic rule. However, while military, business, and political elites have generally respected democratic norms of political competition, disillusionment with mainstream political parties, corruption, failure to control organized crime, declines in voter turnout, and withdrawal from civic life all present challenges for democratic governance (Howard 2003, Ramet 1999, Beetham 2004; Diamond and Morlino 2005; Mainwaring and Hagopian 2005; O ́Donnell 2004a and 2004b; Powell 2004; Rueschemeyer 2004). As the consolidation of democracy ultimately depends upon democratic legitimacy, some see in these trends the risk of a more widespread appeal for demagogic populism or electoral authoritarianism, citing cases such as Venezuela and Russia as examples (Gershman 2007). This paper examines a neglected difference in the analysis of civil society trajectories: whether a society transitioned from authoritarian or totalitarian rule.

description: It was found that, although isovalent, Rh substituted for Ir in Sr$_2$IrO$_4$ may trap one electron inducing effective hole doping of Ir sites. Transport and thermoelectric measurements on Sr$_2$Ir$_{1-x}$Rh$_x$O$_4$ single crystals presented here reveal the existence of an electron-like contribution to transport, in addition to the hole-doped one. As no electron band shows up in ARPES measurements, this points to the possibility that this hidden electron may delocalize in disordered clusters.

description: Combining the $b\to sμ^+μ^-$ anomaly and dark matter observables, we study the capability of LHC to test dark matter, $Z^{\prime}$, and vector-like quark. We focus on a local $U(1)_{L_μ-L_τ}$ model with a vector-like $SU(2)_L$ doublet quark $Q$ and a complex singlet scalar whose lightest component $X_I$ is a candidate of dark matter. After imposing relevant constraints, we find that the $b\to sμ^+μ^-$ anomaly and the relic abundance of dark matter favor $m_{X_I}< 350$ GeV and $m_{Z^{\prime}}< 450$ GeV for $m_Q

description: We investigate an economic system in which one large agent - the Japan government changes the environment of numerous smaller agents - the Japan agriculture producers by indirect regulation of prices of agriculture goods. The reason for this intervention was that before the oil crisis in 1974 Japan agriculture production prices exhibited irregular and large amplitude changes. By means of analysis of correlations and a combination of singular spectrum analysis (SSA), principal component analysis (PCA), and time delay phase space construction (TDPSC) we study the influence of the government measures on the domestic piglet prices and production in Japan. We show that the government regulation politics was successful and leaded (i) to a decrease of the nonstationarities and to increase of predictability of the piglet price; (ii) to a coupling of the price and production cycles; (iii) to increase of determinism of the dynamics of the fluctuations of piglet price around the year average price. The investigated case is an example confirming the thesis that a large agent can change in a significant way the environment of the small agents in complex (economic or financial) systems which can be crucial for their survival or extinction.

description: We define a multivariate polynomial that generalizes several interlace polynomials defined by Arratia, Bollobas and Sorkin on the one hand, and Aigner and van der Holst on the other. We follow the route traced by Sokal, who defined a multivariate generalization of Tutte's polynomial. We also show that bounded portions of our interlace polynomial can be evaluated in polynomial time for graphs of bounded clique-width. Its full evaluation is necessarly exponential just because of the size of the result.

description: Σκοπός της συγκεκριμένης έρευνας ήταν η διερεύνηση της επίδρασης ενός προγράμματος μουσικοκινητικής αγωγής στις βασικές δεξιότητες μετακίνησης και το ρυθμό παιδιών προσχολικής ηλικίας. Η ομάδα παρέμβασης αποτελούνταν από 17 παιδιά προσχολικής ηλικίας και η ομάδα ελέγχου από 16. Η ομάδα παρέμβασης ακολούθησε ένα πρόγραμμα μουσικοκινητικής αγωγής διάρκειας οχτώ εβδομάδων, δύο φορές την εβδομάδα διάρκειας 45 λεπτών. Η ομάδα ελέγχου στο ίδιο διάστημα διδάχτηκε τις ίδιες δεξιότητες δίχως τη συνοδεία μουσικής. Πριν και μετά την παρέμβαση για τη μέτρηση των βασικών δεξιοτήτων μετακίνησης εφαρμόστηκε το TestofGrossMotor Development-2 (Ulrich, 2000) και για τη μέτρηση του ρυθμού το K-Rhythmtest (Chatzopoulos, etal., 2019).Η στατιστική επεξεργασία έγινε με τη μέθοδο ανάλυσης διακύμανσης με επαναλαμβανόμενες μετρήσεις. Σε σχέση με τις βασικές δεξιότητες μετακίνησης και οι δυο ομάδες παρουσίασαν σημαντική βελτίωση μεταξύ της αρχικής και της τελικής μέτρησης. Σε σχέση με τις διαφορές μεταξύ των ομάδων η ομάδα παρέμβασης παρουσίασε καλύτερες επιδόσεις μόνο στη δεξιότητα γκαλόπ. Σε σχέση με το ρυθμό, η ομάδα παρέμβασης παρουσίασε στο τέλος σημαντικά καλύτερες επιδόσεις από την ομάδα ελέγχου. Το συμπέρασμα της εργασίας είναι ότι ένα πρόγραμμα μουσικοκινητικής αγωγής μπορεί να συμβάλλει στη βελτίωση των βασικών δεξιοτήτων μετακίνησης και ρυθμού σε παιδιά προσχολικής ηλικίας.
description: The aim of this research was to investigate the impact of a music-movement programme on the development of basic motor skills and rhythm in pre-school children. Seventeen pre-school children were included in the intervention group and sixteen in the control group. The intervention group followed an eight-week music-movement programme, taking place twice a week, with each session lasting 45 minutes.During the same time period, the control group followed a standard non-music programme for increasing the same skills. Before and after the intervention, the Test of Gross Motor Development-2 (Ulrich, 2000) was used to measure the basic motor skills and the K-Rhythm test (Chatzopoulos, et al., 2019) to measure rhythm. The data were analysed using repeated measures analysis of variance. At the end of the intervention, both groups significantly improved their basic motor skills when compared to the baseline. Between-group comparisons showed that gallop was the only basic motor skill that significantly improved in the intervention group at the end of the study. Rhythm was also significantly improved in the intervention group when compared to the control group at the end of the study. In conclusion, this research found that a music-movement programme can contribute to the improvement of basic motor skills and rhythm in pre-schoolchildren.

description: Taking the recently reported non-zero rotation angle of the cosmic microwave background (CMB) linear polarization $β=0.35\pm0.14{\rm\, deg}$ as the hint for a pseudo Nambu-Goldstone boson quintessence dark energy (DE), we study the electroweak (EW) axion quintessence DE model where the axion mass is generated by the EW instantons. We find that the observed value of $β$ implies a non-trivial $U(1)$ electromagnetic anomaly coefficient ($c_γ$), once the current constraint on the DE equation of state is also taken into account. With the aid of the hypothetical high energy structure of the model inspired by the experimentally inferred $c_γ$, the model is shown to be able to make prediction for the current equation of state ($w_{\rm DE,0}$) of the quintessence DE. This is expected to make our scenario distinguishable in comparison with the cosmological constant ($w=-1$) and testable in future when the error in the future measurement of $w_{\rm DE,0}$ is reduced to $\mathcal{O}(1)\%$ level ($δw=\mathcal{O}(10^{-2})$).

Perturbations of the coupled Jeffery-Stokes equations

description: This paper seeks to provide clues as to why experimental evidence for the alignment of slender fibers in semi-dilute suspensions under shear flows does not match theoretical predictions. This paper posits that the hydrodynamic interactions between the different fibers that might be responsible for the deviation from theory, can at least partially be modeled by the coupling between Jeffery's equation and Stokes' equation. It is proposed that if the initial data is slightly non-uniform, in that the probability distribution of the orientation has small spacial variations, then there is feedback via Stokes' equation that causes these non-uniformities to grow significantly in short amounts of time, so that the standard uncoupled Jeffery's equation becomes a poor predictor when the volume ratio of fibers to fluid is not extremely low. This paper provides numerical evidence, involving spectral analysis of the linearization of the perturbation equation, to support this theory. This paper differs from the published version in that it contains a corrogendum at the end.
Realities about role drama: the trials of one teacher’s year-long implementation

description: Although role drama is being regarded as a key ingredient in the recipe for children's learning, it appears to be making surprisingly little impact on the methods used by many teachers. After wading through related literature, and talking with colleagues, I realized that role drama is not growing to its fullest potential because it appears threatening to classroom teachers who are not drama specialists. In order to bring this problematic issue into clear view, I decided to document the implementation of role drama by a teacher in her classroom. Dianne, the brave grade one (year two of the primary program) teacher who volunteered for my study, had completed one Drama in Education teacher training course at The University of British Columbia. Like many of her colleagues, Dianne was hesitant about using role drama, but, since she was aware of its value as a teaching tool, she was eager to help me uncover the difficulties. Over a time span of approximately nine months, I videotaped 15 drama sessions, conducted audiotaped reviews with Dianne following each session, collected Dianne's reflective notes related to her observations of the videos (and maintained my own reflective journal, too), and audiotaped two overview discussions regarding the entire implementation and the implications for teachers in classrooms and for Drama in Education teacher training courses. The documentation is sometimes exhilarating, sometimes disheartening -- but, invariably, it is honest.

description: We present a numerical technique to compute the gravitational lensing induced by simulated haloes. It relies on a 2D-Tree domain decomposition in the lens plane combined with a description of N-Body particles as extended clouds with a non-singular density. This technique is made fully adaptive by the use of a density-dependent smoothing which allows one to probe the lensing properties of haloes from the densest regions in the center or in substructures to the low-density regions in the outskirts. 'Smooth Particle Lensing' has some promising features. First, the deflection potential, the deflection angles, the convergence and the shear are direct and separate end-products of the SPL calculation and can be computed at an arbitrary distribution of points on the lens plane. Second, this flexibility avoids the use of interpolation or a finite differentiation procedure on a grid, does not require padding the region with zeros and focuses the computing power on relevant regions. The SPL algorithm is tested by populating isothermal spheres and ellipsoids with particles and then comparing the lensing calculations to the classical FFT-based technique and analytic solutions. We assess issues related to the resolution of the lensing code and the limitations set by the simulations themselves. We conclude by discussing how SPL can be used to predict the impact of substructures on strong lensing and how it can be generalized to weak lensing and cosmic shear simulations.
