Relationships between cognitive and linguistic processes and second language production in French immersion programmes
Creators: name: Bournot-Trites, Monique
Publisher: name: University of British Columbia
Year: 2009

description: Some researchers believe that all French immersion students speak the same way and that they make many transfer errors (borrowing English structures). Although these beliefs are not founded on rigorous observations, current teaching strategies emphasize repeating correct patterns rather than teaching according to student's individual differences. My study posed two main questions. First, are there individual differences in the quality of French spoken by French immersion students? Second, do individual differences in cognitive and linguistic processes influence the type and frequency of errors observed in French immersion students' language production? To analyse individual differences in linguistic processes, I used variables from verbal learning theory that measure Paradigmatic and Syntagmatic processes. I analysed differences in cognitive processes with the PASS (Planning, Arousal/Attention, Simultaneous and Successive processes) cognitive theory. PASS is operationalized in the Cognitive Assessment System test (CAS). These theories generated a secondary purpose for the study: to verify and explain the findings of Jarman's (1980) study concerning the parallelism between Paradigmatic and Simultaneous processes, and between Syntagmatic and Successive processes. Data came from 89 girls and 63 boys from anglophone families in grade three French immersion schools in British Columbia. I analysed four areas of individual differences (Paradigmatic and Syntagmatic processes; Simultaneous and Successive processes; Planning; and Attention), and the relationship between these processes with Vocabulary, Grammar, and Transfer Errors in oral and written French language production. LISREL measurement models did not converge due to variables' low correlation. Relationships between the variables were not found probably because of low reliabilities of the CAS measures. A subsequent analysis used observed variables' models (multiple regressions), rather than latent variables' models. The strongest relation was between Planning and Attention, and Transfer Errors. Grammar Errors, rather than Transfer Errors prevailed. Consequently, I suggested teaching methods reinforcing communicative sentence structures. As in Jarman (1980), cognitive and linguistic processes were not demonstrably parallel. Contrary to what verbal learning researchers thought, various linguistic processes' measures are not equivalent. Linguistic measures' constraint level as well as Planning level affected my results. For further research, I proposed a model of linguistic tasks of various constraint levels.

Εξετάσαμε την πορεία την οποία σημείωσε το Δικαστήριο προκειμένου να καθιερώσει την αστική ευθύνη των κρατών μελών της ΕΕ σε περίπτωση που αποτυγχάνουν να σεβαστούν το ενωσιακό δίκαιο. Ακόμη αναφερθήκαμε αναλυτικά στις απόψεις που έχει εκφράσει η θεωρία σχετικά με τα ζητήματα της αστικής ευθύνης.
description: The aim of the present thesis was to present the basic aspects of the State liability, as formed under the catalytic influence of the jurisprudence of the Court of the European Union. We examined the path that the Court followed in order to establish the liablitity of the member states of the EU, when they fail to respect the EU law. Furthermore, we analyzed the views that have been adopted by the theory, on the questions of the liability.

description: Online selection is an essential step to collect the most relevant collisions from the very large number of collisions inside the ATLAS detector at the Large Hadron Collider (LHC). The Fast TracKer (FTK) is a hardware based track finder, built to greatly improve the ATLAS trigger system capabilities for identifying interesting physics processes through track-based signatures. The FTK is reconstructing after each Level-1 trigger all tracks with $ p_{\textrm T}>1 $ GeV, such that the high-level trigger system gains access to track information at an early stage. FTK track reconstruction starts with a pattern recognition step. Patterns are found with hits in seven out of eight possible detector layers. Disabled detector modules, as often encountered during LHC operation, lead to efficiency losses. To recover efficiency, WildCards (WC) algorithms are implemented in the FTK system. The WC algorithm recovers inefficiency but also causes high combinatorial background and thus increased data volumes in the FTK system, possibly exceeding hardware limitations. To overcome this, a refined algorithm to select patterns is developed and investigated in this article.

description: Metal halide perovskites are an important class of emerging semiconductors. Their charge dynamics is poorly understood due to limited knowledge of defect physics and charge recombination mechanisms. Nevertheless, classical ABC and Shockley-Read-Hall (SRH) models are ubiquitously applied to perovskites without considering their validity. Herein, an advanced technique mapping photoluminescence quantum yield (PLQY) as a function of both the excitation pulse energy and repetition frequency is developed and employed to examine the validity of these models. While ABC and SRH fail to explain the charge dynamics in a broad range of conditions, the addition of Auger recombination and trapping to the SRH model enables a quantitative fitting of PLQY maps and low-power PL decay kinetics, and extracting trap concentrations and efficacies. Higher-power PL kinetics requires the inclusion of additional non-linear processes. The PLQY mapping developed herein is suitable for a comprehensive testing of theories and is applicable to any semiconductor.

description: Mixing transformations in quantum field theory are non-trivial, since they are intimately related to the unitary inequivalence between Fock spaces for fields with definite mass and fields with definite flavor. Considering the superposition of two neutral scalar (spin-0) bosonic fields, we investigate some features of the emerging condensate structure of the flavor vacuum. In particular, we quantify the flavor vacuum entanglement in terms of the von Neumann entanglement entropy of the reduced state. Furthermore, in a suitable limit, we show that the flavor vacuum has a structure akin to the thermal vacuum of Thermo Field Dynamics, with a temperature dependent on both the mixing angle and the particle mass difference.

description: Perturbative dynamics of gravity is investigated for high energy scattering and in black hole backgrounds. In the latter case, a straightforward perturbative analysis fails, in a close parallel to the failure of the former when the impact parameter reaches the Schwarzschild radius. This suggests a flaw in a semiclassical description of physics on spatial slices that intersect both outgoing Hawking radiation and matter that has carried information into a black hole; such slices are instrumental in a general argument for black hole information loss. This indicates a possible role for the proposal that nonperturbative gravitational physics is intrinsically nonlocal.

description: Aims. We study the changes in geometry of the truncated disc and the inner hot-flow of GX 339-4 by analyzing the Power SpectralDensity (PSD) extracted from six XMM-Newton observations taken at the very end of an outburst. Methods. A theoretical model of the PSD of GX 339-4 in the 0.3-0.7 keV (thermal reverberation dominated) and 0.7-1.5 keV (disc continuum dominated) energy bands is developed. The model assumes the standard accretion disc to be truncated at a specific radius, inside of which are two distinct hot-flow zones: one spectrally soft and the other spectrally hard. The effects of disc-fluctuations and thermal reverberation are taken into account. Results. This model successfully produces the traditional bumpy PSD profiles and provides good fits to the GX 339-4 data. The truncation radius is found to increase from $r_{\rm trc}$ $\sim$ 10 to 55 $r_{\rm g}$ as the source luminosity decreases, strongly confirming that the truncation radius can be characterized as a function of luminosity. Keeping in mind the large uncertainty in previous measurements of the truncation radius, our values are larger than some obtained from spectroscopic analysis, but smaller than those implied from reverberation lag analysis. Furthermore, the size of two inner hot-flow zones which are spectrally hard and spectrally soft are also growing from $\sim$ 5 to 27 $r_{\rm g}$ and from $\sim$ 3 to 26 $r_{\rm g}$, respectively, as the flux decreases. We find that the radial range of inner hard zone is always larger than the range of the soft hot-flow zone, but by a comparatively small factor of $\sim$ 1.1-2.2

description: We focus on the recognition of Dyck-n ($\mathcal{D}_n$) languages with self-attention (SA) networks, which has been deemed to be a difficult task for these networks. We compare the performance of two variants of SA, one with a starting symbol (SA$^+$) and one without (SA$^-$). Our results show that SA$^+$ is able to generalize to longer sequences and deeper dependencies. For $\mathcal{D}_2$, we find that SA$^-$ completely breaks down on long sequences whereas the accuracy of SA$^+$ is 58.82$\%$. We find attention maps learned by $\text{SA}{^+}$ to be amenable to interpretation and compatible with a stack-based language recognizer. Surprisingly, the performance of SA networks is at par with LSTMs, which provides evidence on the ability of SA to learn hierarchies without recursion.

description: The purpose of this study was to investigate the role of gender, body mass index and physical activity in body dissatisfaction, drive for thinness in children aged between 11 and 13 years old. Three hundred and fifty five children, 170 boys and 185 girls-participated in the survey. All of the participants have filled in questionnaires of demographic characteristics, physical activity, body dissatisfaction, drive for thinness (EDI-2 for children) and EAT-26 for children. The results showed that girls and overweight and obese children have higher average body dissatisfaction and drive for thiness than boys and normal weight children have. In boys there is an inverse relationship between physical activity and factors of EDI-2-ch and EAT-26-ch. The conclusion is that sex, body weight and physical activity are factors that differentiate, provide or/and affect the physical dissatisfaction, the motivation for weight loss and τηε tendency to display eating disorders.

The YM sector of the model consists of the usual YM term and the next higher order term of the YM hierarchy, which is required by the scaling condition for the existence of finite energy solutions. The basic features of two different types of configurations are studied, corresponding to (multi)solitons with topological charge $n^2$, and soliton--antisoliton pairs with zero topological charge.

Rural third-grade children’s social and psychological occupational gender-types : the relationship of maternal work patterns and attitudes
Creators: name: Vaillancourt, Tracy
Publisher: name: University of British Columbia
Year: 2009

description: The present study examined third grade students' (N = 52) social and psychological occupational gender stereotypes in relation to their mothers' work patterns and attitudes toward women in a rural context. The results indicated that rural children not only aspire to and expect to hold gender-traditional jobs (psychological dimension), but they also recognize that certain occupations are typically filled by women or men (social dimension). Specifically, males reported more traditional occupational gender stereotypes for both themselves (psychological dimension) and others (social dimension), and overall, children perceived more traditional occupational gender stereotypes for themselves (psychological dimension) than others (social dimension). The students' social and psychological occupational gender stereotypes were not found to be related to the traditionality of their mothers employment nor to the traditionality of their mothers attitudes concerning the roles of women. Implications for education and future research are discussed.

description: Shells in Elliptical Galaxies are faint, sharp-edged features, believed to provide evidence of a recent ($\sim 0.5 - 2 \times 10^9$ years ago) merger event. We analyse the Globular Cluster (GC) systems of six shell elliptical galaxies, to examine the effects of mergers upon the GC formation history. We examine the colour distributions, and investigate differences between red and blue globular cluster populations. We present luminosity functions, spatial distributions and specific frequencies ($S_N$) at 50 kpc radius for our sample. We present V and I magnitudes for cluster candidates measured with the HST Advanced Camera for Surveys (ACS). Galaxy background light is modelled and removed, and magnitudes are measured in 8 pixel (0.4 arcsec) diameter apertures. Background contamination is removed using counts from HDFS. We find that the colour distributions for NGC 3923 and NGC 5982 have a bimodal form typical of bright ellipticals, with peaks near $V-I=0.92 \pm 0.04$ and $V-I=1.18 \pm 0.06$. In NGC 7626, we find in addition a population of abnormally luminous clusters at $M_I=-12.5$. In NGC 2865 we find an unusually blue population, which may also be young. In NGC1344 and NGC474 the red cluster population is marginally detected. The radial surface density profiles are more flattened than the galaxy light in the cores. As already known, in NGC3923, which has a high $S_N$ of 5.6, the radial density distribution is more shallower than the diffuse galaxy light. The clusters in NGC 2865 and NGC 7626 provide evidence for formation of a population associated with a recent merger. In the other galaxies, the properties of the clusters are similar to those observed in other, non-shell, elliptical galaxies.

description: ASTROD I is a planned interplanetary space mission with multiple goals. The primary aims are: to test General Relativity with an improvement in sensitivity of over 3 orders of magnitude, improving our understanding of gravity and aiding the development of a new quantum gravity theory; to measure key solar system parameters with increased accuracy, advancing solar physics and our knowledge of the solar system and to measure the time rate of change of the gravitational constant with an order of magnitude improvement and the anomalous Pioneer acceleration, thereby probing dark matter and dark energy gravitationally. It is an international project, with major contributions from Europe and China and is envisaged as the first in a series of ASTROD missions. ASTROD I will consist of one spacecraft carrying a telescope, four lasers, two event timers and a clock. Two-way, two-wavelength laser pulse ranging will be used between the spacecraft in a solar orbit and deep space laser stations on Earth, to achieve the ASTROD I goals. A second mission, ASTROD II is envisaged as a three-spacecraft mission which would test General Relativity to one part per billion, enable detection of solar g-modes, measure the solar Lense-Thirring effect to 10 parts per million, and probe gravitational waves at frequencies below the LISA bandwidth. In the third phase (ASTROD III or Super-ASTROD), larger orbits could be implemented to map the outer solar system and to probe primordial gravitational-waves at frequencies below the ASTROD II bandwidth.

description: Belle II is a rapidly growing collaboration with members from one hundred and nineteen institutes spread around the globe. The software development team of the experiment, as well as the software users, are very much decentralised. Together with the active development of the software, such decentralisation makes the adoption of the latest software releases by users an essential, but quite challenging task. To ensure the relevance of the documentation, we adopted the policy of in-code documentation and configured a website that allows us to tie the documentation to given releases. To prevent tutorials from becoming outdated, we covered them by unit-tests. For the user support, we use a question and answer service that not only reduces repetition of the same questions but also turned out to be a place for discussions among the experts. A prototype of a metasearch engine for the different sources of documentation has been developed. For training of the new users, we organise centralised StarterKit workshops attached to the collaboration meetings. The materials of the workshops are later used for self-education and organisation of local training sessions.

description: Em meio ao fenômeno da "Onda Azul" na América Latina, esta pesquisa examina a política externa de dois líderes proeminentes: Mauricio Macri, da Argentina, e Jair Bolsonaro, do Brasil. Ambos são emblemáticos do surgimento conservador na região, no entanto, adotaram estratégias diplomáticas distintas. Macri, focando na recuperação econômica argentina, procurou estabelecer relações multilaterais equilibradas, demonstrando uma flexibilidade pragmática nas relações internacionais. Em contraste, Bolsonaro adotou uma abordagem mais ideológica e protecionista, influenciada, em parte, pelo conservadorismo norte-americano contemporâneo. Estas discrepâncias ressaltam que, mesmo sob uma onda ideológica comum, nuances nacionais moldam a política externa. Esta análise comparativa é fundamental para acadêmicos e profissionais das Relações Internacionais, enfatizando a complexidade e diversidade inerente aos movimentos políticos regionais.

description: Differential inclusive-jet cross sections have been measured for different jet radii in neutral current deep inelastic ep scattering for boson virtualities Q^2 > 125 GeV^2 with the ZEUS detector at HERA using an integrated luminosity of 81.7 pb^-1. Jets were identified in the Breit frame using the k_T cluster algorithm in the longitudinally inclusive mode for different values of the jet radius R. Differential cross sections are presented as functions of Q^2 and the jet transverse energy, E_T,B^jet. The dependence on R of the inclusive-jet cross section has been measured for Q^2 > 125 and 500 GeV^2 and found to be linear with R in the range studied. Next-to-leading-order QCD calculations give a good description of the measurements for 0.5 <= R <= 1. A value of alpha_s(M_Z) has been extracted from the measurements of the inclusive-jet cross-section dsigma/dQ^2 with R=1 for Q^2 > 500 GeV^2: alpha_s(M_Z) = 0.1207 +- 0.0014 (stat.) -0.0033 +0.0035 (exp.) -0.0023 +0.0022 (th.). The variation of alpha_s with E_T,B^jet is in good agreement with the running of alpha_s as predicted by QCD.

description: Learning to locomote is one of the most common tasks in physics-based animation and deep reinforcement learning (RL). A learned policy is the product of the problem to be solved, as embodied by the RL environment, and the RL algorithm. While enormous attention has been devoted to RL algorithms, much less is known about the impact of design choices for the RL environment. In this paper, we show that environment design matters in significant ways and document how it can contribute to the brittle nature of many RL results. Specifically, we examine choices related to state representations, initial state distributions, reward structure, control frequency, episode termination procedures, curriculum usage, the action space, and the torque limits. We aim to stimulate discussion around such choices, which in practice strongly impact the success of RL when applied to continuous-action control problems of interest to animation, such as learning to locomote.

description: The Shishkin's solutions of the Dirac equation in spherical moving frames of the de Sitter spacetime are investigated pointing out the set of commuting operators whose eigenvalues determine the integration constants. It is shown that these depend on the usual angular quantum numbers and, in addition, on the value of the scalar momentum. With these elements a new result is obtained finding the system of solutions normalized (in generalized sense) in the scale of scalar momentum.

description: We study particular classes of states on the Weyl algebra $\mathcal{W}$ associated with a symplectic vector space $S$ and on the von Neumann algebras generated in representations of $\mathcal{W}$. Applications in quantum physics require an implementation of constraint equations, e.g., due to gauge conditions, and can be based on so-called Dirac states. The states can be characterized by nonlinear functions on $S$ and it turns out that those corresponding to non-trivial Dirac states are typically discontinuous. We discuss general aspects of this interplay between functions on $S$ and states, but also develop an analysis for a particular example class of non-trivial Dirac states. In the last part, we focus on the specific situation with $S = L^2(\mathbb{R}^n)$ or test functions on $\mathbb{R}^n$ and relate properties of states on $\mathcal{W}$ with those of generalized functions on $\mathbb{R}^n$ or with harmonic analysis aspects of corresponding Borel measures on Schwartz functions and on temperate distributions.

description: Η σχέση της λογοτεχνίας με την ιστορία μπορεί να περιγραφτεί από τα λόγια του Γ. Λιχτενμπεργκ: “Διαβάζω σημαίνει δανείζομαι; παράγομαι δικες μου σκέψεις, εξοφλώ.” Παρομοίως, η λογοτεχνία δανείζεται σενάρια και χαρακτήρες από ιστορικές πληροφορίες; εξοφλεί όμως το χρέος της για την ιστοριογραφία, δίνοντας ιδέες για καινοτόμους τρόπους παρατήρησης και ερμηνευσης των γνωστών ιστορικών γεγονότων, για καινούριες όψεις της Ιστορίας. Το θέμα αυτής της εργασίας είναι η μετά-ιστοριογραφική λογοτεχνία του 20ου αιώνα και ο διάλογος της με την φιλοσοφία της Ιστορίας; στο επίκεντρο της έρευνας βρίσκεται το πικαρικό μυθιστόρημα και ο αντι-ήρωας πρωταγωνιστής του. Ως παραδείγματα αναλύονται τα εξής έργα: Το Τενεκεδένιο Ταμπούρλο του Γκυντερ Γκρας, Υπηρέτησα τον Βασιλιά της Αγγλίας του Μποχουμιλ Χραμπαλ, Φορεστ Γκαμπ του Γουινστον Γκρουμ, Catch-22 του Τζοζεφ Χελερ και Σελεπκο Λαβοτσκα: Ημερολόγιο ενός Ήρωα του Έθνους του Γιουρι Τυς-Κροχμαλιουκ. Στην έρευνα δίνεται η έμφαση στα στοιχεία της μετά-ιστοριογραφικής λογοτεχνίας και την επίδραση τους στον αναγνώστη, που πρέπει να βρει δικό του τρόπο να εξερευνεί και να ερμηνεύει την λογοτεχνική όσο και την ιστορική πραγματικότητα.
description: The relations of literature and history could be described by an aphorism by G. Chr. Lichtenberg: „To read means to borrow; to create out of one's readings is paying off one's debts.“ In a similiar way, literature borrows plots, sceneries and characters from what is known as „historical reality“; what is paid off to historiography are new viewpoints and innovative ways of rethinking and reimagining the history we know. The topic of this research is interaction of 20th century metahistoriographic fiction with the post-modern philosophy of history as well as the post-modern historiographic narration; it focuses on the genre of picaresque novel and the figure of anti-hero. Following novels are examined: Günter Grass’ The Tin Drum, Bohumil Hrabals I Served The King Of England, Winston Grooms Forrest Gump, Joseph Hellers Catch-22, Yurij Tys-Krochmaljuks Selepko Lawotchka. Diary Of A National Hero. Dealing with historiographical theoretical basis as well as with text examples, demonstration and analysis of metahistoriographic narration elements is provided. Following aspects are approached: 1) creating awareness of literary elements in historiographic narration; 2) the role of oral history and eyewitness accounts as the central media of historical information; 3) unreliable narration in eyewitness accounts and its function; 4) ways of picturing historical events and interferences of facts and fiction; 5) methods of interaction with the reader; a call for active reception and critical evaluation of literary as well as historical reality.
Singularly Perturbed Monotone Systems and an Application to Double Phosphorylation Cycles

description: The theory of monotone dynamical systems has been found very useful in the modeling of some gene, protein, and signaling networks. In monotone systems, every net feedback loop is positive. On the other hand, negative feedback loops are important features of many systems, since they are required for adaptation and precision. This paper shows that, provided that these negative loops act at a comparatively fast time scale, the main dynamical property of (strongly) monotone systems, convergence to steady states, is still valid. An application is worked out to a double-phosphorylation ``futile cycle'' motif which plays a central role in eukaryotic cell signaling.

Death as true bridge
Creators: name: Rosenberg, Margot Claire
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, storytelling was used as a bridge to dialogue with young children around death. A children's story with a death theme was read by either the author or her colleague to four small groups of children ages three to six. These story sessions were part of the children's weekly routine, and relationships between the children and their respective storytellers were previously established and on-going. The spontaneous reactions, questions, comments, and stories that the children interjected during the stories are woven throughout the text. Interviews with this co-storyteller/colleague and another preschool teacher at the same school were conducted to ascertain whether or not they had discussed death in their early childhood classrooms and if so how, their ideas and beliefs about children's perceptions of death, their own experiences with death, and whether or not they thought these personal experiences influence their curricular decisions. These story sessions and interviews provided a framework within which the author could reflect upon and share her own experiences and struggles with death, and her grief over the recent death of her mother. Journal entries, dreams, and stories past and present are interspersed throughout the text in an attempt to document the ways in which participating in and then writing about these experiences have impacted her as a storyteller, researcher, teacher, and daughter. These many voices are woven within three themes, or chapters: other in self, gain in loss, and life in death. Death is used as the medium with which to bridge each of these binary opposites. This thesis explores ways of doing as well as ways of being with children and death in the classroom, with the hope that educators and parents might choose to broach this subject with the children in their lives. This thesis concludes with the author's realization that death has taught her to reach; reach out to children, teachers, graduate students, the bereaved, and others who choose to listen to the stories she weaves.

Entangled gene regulatory networks with cooperative expression endow robust adaptive responses to unforeseen environmental changes

description: Living organisms must respond to environmental changes. Generally, accurate and rapid responses are provided by simple, unidirectional networks that connect inputs with outputs. Besides accuracy and speed, biological responses should also be robust to environmental or intracellular noise and mutations. Furthermore, cells must also respond to unforeseen environmental changes that have not previously been experienced, to avoid extinction prior to the evolutionary rewiring of their networks, which takes numerous generations. We have investigated gene regulatory networks that mutually activate or inhibit, and have demonstrated that complex entangled networks can make appropriate input-output relationships that satisfy the robust and adaptive responses required for unforeseen challenges. Such entangled networks function for sloppy and unreliable responses with low Hill coefficient reactions for the expression of each gene. To compensate for such sloppiness, several detours in the regulatory network exist. By taking advantage of the averaging over such detours, the network shows a higher robustness to environmental and intracellular noise as well as to mutations in the network, when compared to simple unidirectional circuits. Furthermore, the appropriate response to unforeseen challenges, allowing for functional outputs, is achieved as many genes exhibit similar dynamic expression responses, irrespective of inputs, as confirmed by applying dynamic time warping and dynamic mode decomposition. As complex entangled networks are common in gene regulatory networks and global gene expression responses are observed in microbial experiments, the present results provide a novel design principle for cellular networks.

description: We analyse the geometry of four-dimensional bosonic manifolds arising within the context of $N=4, D=1$ supersymmetry. We demonstrate that both cases of general hyper-Kähler manifolds, i.e. those with translation or rotational isometries, may be supersymmetrized in the same way. We start from a generic N=4 supersymmetric three-dimensional action and perform dualization of the coupling constant, initially present in the action. As a result, we end up with explicit component actions for $N=4, D=1$ nonlinear sigma-models with hyper-Kähler geometry (with both types of isometries) in the target space. In the case of hyper-Kähler geometry with translational isometry we find that the action possesses an additional hidden N=4 supersymmetry, and therefore it is N=8 supersymmetric one.

description: The random intensity distribution observed due to the propagation of a coherent beam of light through a scattering medium is known as a speckle pattern. The interaction of the speckles with a birefringent crystal, here, YVO4 results in the e-ray and o-ray speckles. It is observed that the e-ray and o-ray speckles experience an angular shift with the rotation of the crystal and the shift depends on the rotation angle of the crystal. It is also found that the rate of the shift is different for e-ray and o-ray speckles, and is independent of the topological charge of the beam incident on the scattering medium. The observed rate of shift of the speckle pattern is found to be same as that of the e-ray and o-ray beams. It is experimentally demonstrated that the rotation of a birefringent crystal can be tracked very accurately from the speckle shift measurement.
