Bilingualism in infancy : a window on language acquisition
Creators: name: Byers-Heinlein, Krista
Publisher: name: University of British Columbia
Year: 2010

description: To rise to the challenge of acquiring their native language, infants must deploy tools to support their learning. This thesis compared infants growing up in two very different language environments, monolingual and bilingual, to better understand these tools and how their development and use changes with the context of language acquisition. The first set of studies − Chapter 2 − showed that infants adapt very early-developing tools to the context of their prenatal experience. Newborns born to bilingual mothers directed their attention to both of their native languages, while monolinguals preferred listening to their single native language. However, prenatal bilingual experience did not result in language confusion, as language discrimination was robustly maintained in both monolinguals and bilinguals. Thus, learning mechanisms allow experience-based listening preferences, while enduring perceptual sensitivities support language discrimination even in challenging language environments. Chapter 3 investigated a fundamental word learning tool: the ability to associate word and object. Monolinguals and bilinguals showed an identical developmental trajectory, suggesting that, unlike some aspects of word learning, this associative ability is equivalent across different types of early language environments. Chapters 4 and 5 explored the development of a heuristic for learning novel words. Disambiguation is the strategy of associating a novel word with a novel object, rather than a familiar one. In Chapter 4, disambiguation was robustly demonstrated by 18-month-old monolinguals, but not by age-matched bilinguals and trilinguals. The results supported the “lexicon structure hypothesis”, that disambiguation develops with mounting evidence for a one-to-one mapping between words and their referents, as is typical for monolinguals. For bilinguals, translation equivalents (cross-language synonyms) represent a departure from one-to-one mapping. Chapter 5 directly tested the lexicon structure hypothesis, by comparing subgroups of bilinguals who knew few translation equivalents to bilinguals who knew many. Only the former group showed disambiguation, supporting the lexicon structure hypothesis. The series of studies presented in this thesis provides a window into language acquisition across all infants. Whether growing up monolingual or bilingual, infants harmonize their development and use of the tools of language acquisition to the particular challenges mounted by their language environment.

Subjects: Fine Arts

description: In this paper I will introduce the theories and motivations that contextualize my practice during the course of my 2-year MFA degree. I will start off with an introduction; a brief summary of the events that took place in my country—Egypt, and that instigated my research. In the first chapter, I will investigate the issue of social confinement, and its psychological effect on individuals and groups. The second chapter is an explanation of my visual interpretation of psychological confinement and a closer examination of my artistic work. The third chapter is an analysis and discussion of the conceptual aspects of my use of the term ‘frame,’ in reference to ancient Egyptian mythology and the contemporary term territorialization. The fourth and last chapter is a further application of the notion of territorialization as a critique of street art, as well as a conceptual tool for the investigation of my own practice. I will try to convey the ideological and visual battles that take place between the public and the institution through examples of Egyptian street art and my work.
Modeling magnetar outbursts: Flux enhancements and the connection with short bursts and glitches

Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The availability of a large amount of observational data recently collected from magnetar outbursts is now calling for a complete theoretical study of outburst characteristics. In this letter (the first of a series dedicated to model magnetar outbursts), we tackle the long-standing open issue of whether or not short bursts and glitches are always connected to long-term radiative outbursts. We show that the recent detection of short bursts and glitches seemingly unconnected to outbursts is only misleading our understanding of these events. We show that, in the framework of the starquake model, neutrino emission processes in the magnetar crust limit the temperature, and therefore the luminosity. This natural limit to the maximum luminosity makes outbursts associated with bright persistent magnetars barely detectable. These events are simply seen as a small luminosity increase over the already bright quiescent state, followed by a fast return to quiescence. In particular, this is the case for 1RXS J1708-4009, 1E 1841-045, SGR 1806-20, and other bright persistent magnetars. On the other hand, a similar event (with the same energetics) in a fainter source will drive a more extreme luminosity variation and longer cooling time, as for sources such as XTE J1810-197, 1E 1547-5408 and SGR 1627-41. We conclude that the non-detection of large radiative outbursts in connection with glitches and bursts from bright persistent magnetars is not surprising per se, nor it needs of any revision on the glitches and burst mechanisms as explained by current theoretical models.

The Genealogy of Maiden Names

subject: N+7

description: The Genealogy of Maiden Names is a feminist poetic investigation into and deconstruction of the androcentrism inherent in the practice of genealogy. Genealogy systematically erases women’s narratives from the historical record at the level of the family. Through its erasure of the maternal name, the patrinomial organization of genealogies privileges men as the embodiment of relational narrative. The story of a family is told through the transfer of its name from father to son, and this sequence of entitlement and inheritance is what traditionally defines a family beyond the scope of memory and oral history. Drawing on a number of theoretical and poetic practices, such as homophonic procedures, psychogeographic techniques and decentred treatments of voice, this exploration reconsiders what it means to inherit, to name, to remember, and to be remembered, through an examination of three women whose familial histories and legacies occupy spaces outside of the standard genealogical frame.

description: We apply the principal component analysis and Spearman's correlation test to study the properties of superclusters drawn from the SDSS DR7. We analyse possible selection effects in the supercluster catalogue, study the physical and morphological properties of superclusters, find their possible subsets, and determine scaling relations for superclusters. We show that the parameters of superclusters do not correlate with their distance. The correlations between the physical and morphological properties of superclusters are strong. Superclusters can be divided into two populations according to their total luminosity. High-luminosity superclusters form two sets, more elongated systems with the shape parameter K_1/K_2 < 0.5 and less elongated ones with K_1/K_2 > 0.5. The first two principal components account for more than 90% of the variance in the supercluster parameters and define the fundamental plane, which characterises the physical and morphological properties of superclusters. We use principal component analysis to derive scaling relations for superclusters, in which we combine the physical and morphological parameters of superclusters. Structure formation simulations for different cosmologies, and more data about the local and high redshift superclusters are needed to understand better the evolution and the properties of superclusters.

description: Near continuous outcrop of Pennsylvanian to Early Permian carbonate strata were studied on northwest Ellesmere Island, in the Sverdrup Basin, Arctic Canada. Six sections were examined displaying shallow water facies of the Nansen Formation and deeper water facies of the Hare Fiord Formation. Petrographic analysis and field observations identified 15 microfacies that represent four main depositional environments along a distally steepened ramp. The environments are: restricted shelf, shoal and patch reef, open shelf, and slope with evidence for exponential slope geometry. This is a new interpretation as the Nansen Formation studied to the north was interpreted as a rimmed shelf with a planar slope geometry. Slope morphology is influenced by: climate change, oceanography and prevailing wind direction, and tectonics.

description: Late nineteenth and early twentieth century Freemasonry has generally been understood as a staunchly middle-class organization that promoted class cohesion, and provided a vehicle for social mobility, as well as a means to attain and broadcast respectability. Similarly, the popularity of the order has been regarded as evidence of a late Victorian “flight from domesticity” as men sought to escape the stifling feminine influence in the home and church. The characterization of late Victorian and Edwardian era Freemasonry as a reactionary space fails to account for the personal and emotive functions of Freemasonic ritual. This thesis examines Masonic materials and rituals, especially those surrounding death and dying, and argues that Freemasonry satisfied many deeply personal emotional and religious needs of Canadian men in the early twentieth century.
Detecting population III galaxies with HST and JWST

description: A small fraction of the atomic-cooling halos assembling at z<15 may form out of minihalos that never experienced any prior star formation, and could in principle host small galaxies of chemically unenriched stars. Since the prospects of detecting isolated population III stars appear bleak even with the upcoming James Webb Space Telescope (JWST), these population III galaxies may offer one of the best probes of population III stars in the foreseeable future. By projecting the results from population III galaxy simulations through cluster magnification maps, we predict the fluxes and surface number densities of pop III galaxy galaxies as a function of their typical star formation efficiency. We argue that a small number of lensed population III galaxies in principle could turn up at z=7-10 in the ongoing Hubble Space Telescope survey CLASH, which covers a total of 25 low-redshift galaxy clusters.

description: This study in environmental communication addresses links among land, natural resources and people in a world shaped increasingly by global economic forces and pervaded by the power of pictures. Hosting what has been called the world’s largest industrial project, the bituminous (‘tar’/‘oil’) sands, Alberta has become an epicentre of the clash between economic growth mandated by extractive capitalism and its unsustainable ecological costs. A high-stakes, international public-relations battle has emerged, with independent filmmakers producing documentary films challenging Albertans’ environmental stewardship, and government and industry producing advocacy videos defending it. Situating this negotiation of Alberta’s place-identity in a discourse beginning in 2004—the year the US deemed the extraction of the sands to be economically viable—this study is inspired theoretically by the Canadian critical tradition, notably extensions of Innis’ ideas on communications into environmental studies, and methodologically by arts-based research (re)presenting diversities and complexities of voice, nuances of character and potential affect on audiences that would be diminished in conventional scholarly prose. Thus, this study proceeds in three phases: interviews with commissioning and creative principals of the films/videos; a critical visual framing analysis of that work, focusing on its creators’ positioning of Alberta and broader cultural, political and economic forces at work; and a synthesis and (re)presentation of my findings in a script for a hybridized documentary film. Five conclusions emerging from this study are: (1) place in a globally-recognized, resource-based economy is positioned and contested largely in response to events and to representations of that place originating beyond its borders; (2) in representing resource extraction and its effects, visual strategies focus on both the macro and the micro; (3) visual omissions or denials can be as significant in environmental discourse as explicit representations; (4) producers of films/videos use a wide spectrum of frames ranging from anthropocentric (e.g. denial, progress, money) to ecocentric (e.g. eco-justice, present-minded, ecocide); and (5) the significant costs, production time and distribution challenges of producing and exhibiting documentary films professionally favour presenting generalizations and drama over nuanced details in addressing complex issues like environmental concerns about resource extraction.

description: This thesis examines the potential for the collaborative process as a tool for dispute management in Australian civil matters. It applies exploratory research methods to first understand collaborative practice in its present use, which is predominantly as a tool for family law matters, and then explores how the process can assist parties in other types of dispute. The areas most suited to collaborative practice are identified, and the barriers to its expansion into these fields are considered. The thesis concludes with recommendations to support the expansion of the collaborative process and an illustrative example of how the process might be applied in a commercial setting.

description: In the current study a meshfree Lagrangian particle method for the Landau-Lifshitz Navier-Stokes (LLNS) equations is developed. The LLNS equations incorporate thermal fluctuation into macroscopic hydrodynamics by the addition of white noise fluxes whose magnitudes are set by a fluctuation-dissipation theorem. The study focuses on capturing the correct variance and correlations computed at equilibrium flows, which are compared with available theoretical values. Moreover, a numerical test for the random walk of standing shock wave has been considered for capturing the shock location.

description: The potential applications of nanotechnology in a wide range of areas necessities nano-networking research. Nano-networking is a new type of networking which has emerged by applying nanotechnology to communication theory. Therefore, this dissertation presents a framework for physical layer communications in a nano-network and addresses some of the pressing unsolved challenges in designing a molecular communication system. The contribution of this dissertation is proposing well-justified models for signal propagation, noise sources, optimum receiver design and synchronization in molecular communication channels. The design of any communication system is primarily based on the signal propagation channel and noise models. Using the Brownian motion and advection molecular statistics, separate signal propagation and noise models are presented for diffusion-based and flow-based molecular communication channels. It is shown that the corrupting noise of molecular channels is uncorrelated and non-stationary with a signal dependent magnitude. The next key component of any communication system is the reception and detection process. This dissertation provides a detailed analysis of the effect of the ligand-receptor binding mechanism on the received signal, and develops the first optimal receiver design for molecular communications. The bit error rate performance of the proposed receiver is evaluated and the impact of medium motion on the receiver performance is investigated. Another important feature of any communication system is synchronization. In this dissertation, the first blind synchronization algorithm is presented for the molecular communication channels. The proposed algorithm uses a non-decision directed maximum likelihood criterion for estimating the channel delay. The Cramer-Rao lower bound is also derived and the performance of the proposed synchronization algorithm is evaluated by investigating its mean square error.
The legacy of the Maoist gender project in contemporary China
Creators: name: Huang, Xin
Publisher: name: University of British Columbia
Year: 2010

description: This study examines various ways in which the Maoist gender project manifests itself in Chinese women’s lives today, as conveyed by a range of women currently living in Beijing. Oral histories were collected from fifteen women, four of whom were selected for in-depth analysis using a method informed by narrative studies and feminist approaches to women’s auto/bio/graphy. Judith Butler’s ideas on gender as performative serve as a framework to examine these individual negotiations with changing models of femininity, and the first chapter presents a critical account of the limits and applicability of her theory in this specific transnational context. The four following chapters provide detailed, contextualized analysis of these particular performances of gender in relation to the Maoist model woman (funű, or socialist labourer), whose presence remains in the shadow of the currently preferred nűxing (feminine, consumer-oriented woman), while the even older pre-revolutionary devoted wife and mother remains in the background. Their gender performances bring out the intersections of physical embodiment and the construction of subjectivity through discourse. Analysis of the content of each story is complemented by a discussion of the structure and language of their narratives, including an innovative interviewing method of “telling and retelling”. Hybrid language—various mixtures of official dialect, regional dialects, and imported terms—is a feature that becomes prominent, conveying changing performances of being a woman, as do the visual representations (photographs, artwork) that some of them shared. The analysis reveals how women individually appropriate, resist or synthesize the ideologically motivated models proposed by government and media, from China and from the West. The concept of gender performance as a “project” is introduced to convey both conscious manipulation at the collective level, and personal agency for individuals. This research shows that the Maoist legacy still manifests itself in various ways in the lives of women with different social locations and sexual orientations, and is one of the resources for women to formulate strategies for gender subversion. The persistent existence of this legacy sheds light on how to formulate subversive strategies to challenge the narrowly defined, class-encoded, normative gender model of the post-Mao nüxing, and create a more diverse and democratic gender landscape in China.

description: Protoadditive functors are designed to replace additive functors in a non-abelian setting. Their properties are studied, in particular in relationship with torsion theories, Galois theory, homology and factorisation systems. It is shown how a protoadditive torsion-free reflector induces a chain of derived torsion theories in the categories of higher extensions, similar to the Galois structures of higher central extensions previously considered in semi-abelian homological algebra. Such higher central extensions are also studied, with respect to Birkhoff subcategories whose reflector is protoadditive or, more generally, factors through a protoadditive reflector. In this way we obtain simple descriptions of the non-abelian derived functors of the reflectors via higher Hopf formulae. Various examples are considered in the categories of groups, compact groups, internal groupoids in a semi-abelian category, and other ones.
Epistemic modality and evidentiality in Gitksan at the semantics-pragmatics interface
Creators: name: Peterson, Tyler Roy Gösta
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation provides an empirically driven, theoretically informed investigation of how speakers of Gitksan, a Tsimshianic language spoken in the northwest coast of Canada, express knowledge about the world around them. There are three main goals that motivate this investigation: The first is to provide the first detailed description of the evidential and modal system in Gitksan. The second is to provide a formal semantic and pragmatic account of this system that adequately explains the meanings of the modals and evidentials, as well as how they are used in discourse. The third goal is to examine the specific properties the Gitksan evidential/modal system brings to bear on current theories of semantics and pragmatics, as well as the consequences this analysis has on the study of modality and evidentiality cross-linguistically. In addition to documenting the evidential and modal meanings in Gitksan, I work through a variety of theoretical tools designed to determine what level of meaning the individual evidentials in Gitksan operate on. The current state of research into the connection between evidentiality and epistemic modality has identified two different types of evidentials defined by the level of meaning they operate on: propositional and illocutionary evidentials. These two types correspond to a distinction between modal evidentials and non-modal evidentials respectively. I show that Gitksan has both modal and non-evidentials. This leads to an analysis where the Gitksan modal evidentials are treated as a specialized type of epistemic modals, and the non-modal evidentials are sentential force specifiers. I also identify various features of the evidential system that bring specific issues to bear upon current theories of the semantics and pragmatics of modality. This has four outcomes: first, I present a novel analysis of variable modal force in modals with fixed quantification. Secondly, I discuss the effect of modal evidentials in Conjectural Questions. Thirdly, I analyze how modal and non-modal evidentials interact in discourse contexts in implicating a speaker’s attitude towards the evidence they have for a proposition. And fourthly, I develop the first formal analysis of mirativity and non-literal uses of evidentials, analyzing them both as cases of conversational implicature.
The peculiar properties of horizontal branch stars in omega Centauri

description: We measured temperatures, gravities, and masses for a large sample of blue horizontal branch stars in omega Centauri, comparing the results with theoretical expectations for canonical and He-enriched stars, and with previous measurements in three other clusters. The measured gravities of omega Cen stars are systematically lower than canonical models, in agreement with expectations for He-enriched stars, and contrary to that observed in the comparison clusters. However, the derived masses are unrealistically too low as well. This cannot be explained by low gravities alone, nor by any of the other parameters entering in the calculation. We find that the same stars are not brighter than their analogs in the other clusters, contrary to the expectations of the He-enrichment scenario. The interpretation of the results is thus not straightforward, but they reveal an intrinsic, physical difference between HB stars in omega Cen and in the three comparison clusters.

description: Today digital assistants have become not only a universally recognized area of computer language learning — CALL (computer-assisted language learning), but also an important part of teaching English in general. Computer quest games that appeared several decades ago representing problem tasks, activating cognitive activities as well and increasing students' motivation are of great importance. With the development of the Internet speed and affordable storage costs such segments as online games appeared. Online games allow us to present and master difficult material to any modern gadget in the form of a game. The article demonstrates the effectiveness of the use of interactive methods in foreign language teaching. The main types of educational quests in terms of their general classification and structure are identified. Based on English phrasal verbs, phraseological units, and logic puzzles the article proves that quest game is an innovative method of language teaching.

description: In this paper we report on the bulk features of the hole carved by the companion star in the material ejected during a Type Ia supernova explosion. In particular we are interested in the long term evolution of the hole as well as in its fingerprint in the geometry of the supernova remnant after several centuries of evolution, which is a hot topic in current Type Iasupernovae studies. We use an axisymmetric smoothed particle hydrodynamics code to characterize the geometric properties of the supernova remnant resulting from the interaction of this ejected material with the ambient medium. Our aim is to use supernova remnant observations to constrain the single degenerate scenario for Type Ia supernova progenitors. Our simulations show that the hole will remain open during centuries, although its partial or total closure at later times due to hydrodynamic instabilities is not excluded. Close to the edge of the hole, the Rayleigh-Taylor instability grows faster, leading to plumes that approach the edge of the forward shock. We also discuss other geometrical properties of the simulations, like the evolution of the contact discontinuity.

description: We consider modifications of the nonlinear Schrodinger model (NLS) to look at the recently introduced concept of quasi-integrability. We show that such models possess an infinite number of quasi-conserved charges which present intriguing properties in relation to very specific space-time parity transformations. For the case of two-soliton solutions where the fields are eigenstates of this parity, those charges are asymptotically conserved in the scattering process of the solitons. Even though the charges vary in time their values in the far past and the far future are the same. Such results are obtained through analytical and numerical methods, and employ adaptations of algebraic techniques used in integrable field theories. Our findings may have important consequences on the applications of these models in several areas of non-linear science. We make a detailed numerical study of the modified NLS potential of the form V = |psi|^(2(2+epsilon)), with epsilon being a perturbation parameter. We perform numerical simulations of the scattering of solitons for this model and find a good agreement with the results predicted by the analytical considerations. Our paper shows that the quasi-integrability concepts recently proposed in the context of modifications of the sine-Gordon model remain valid for perturbations of the NLS model.

description: The Ising model S=1/2 and the S=1 model are studied by efficient Monte Carlo schemes on the (3,4,6,4) and the (3,3,3,3,6) Archimedean lattices. The algorithms used, a hybrid Metropolis-Wolff algorithm and a parallel tempering protocol, are briefly described and compared with the simple Metropolis algorithm. Accurate Monte Carlo data are produced at the exact critical temperatures of the Ising model for these lattices. Their finite-size analysis provide, with high accuracy, all critical exponents which, as expected, are the same with the well known 2d Ising model exact values. A detailed finite-size scaling analysis of our Monte Carlo data for the S=1 model on the same lattices provides very clear evidence that this model obeys, also very well, the 2d Ising model critical exponents. As a result, we find that recent Monte Carlo simulations and attempts to define effective dimensionality for the S=1 model on these lattices are misleading. Accurate estimates are obtained for the critical amplitudes of the logarithmic expansions of the specific heat for both models on the two Archimedean lattices.

description: Recent work on classicication of off-shell representations of N-extended worldline supersymmetry without central charges has uncovered an unexpectedly vast number--trillions of even just (chromo)topology types--of so called adinkraic supermultiplets. Herein, we show by explicit analysis that a long-known but rarely used representation, the complex linear supermultiplet, is not adinkraic, cannot be decomposed locally, but may be reduced by means of a Wess-Zumino type gauge. This then indicates that the already unexpectedly vast number of adinkraic off-shell supersymmetry representations is but the proverbial tip of the iceberg.

description: Johne’s disease (JD) is a debilitating chronic enteritis in ruminants caused by Mycobacterium avium subsp. paratuberculosis (Map). JD causes substantial losses to the dairy industry due to reduced milk production, fertility rates and increased culling. The control of JD is complicated by the difficult diagnosis of the disease in its early stages and low sensitivity of the current diagnostics. As Map eventually survives in the host tissue despite of aggressive immune response, our aim was to profile early Map - induced immune responses in dairy calves infected with a high or low dose of Map for a 6-month period. The circulating T-lymphocytes were profiled by their phenotypic markers and signature cytokines. Regulatory T cell markers (Foxp3, IL-10 and TGF-β) were all upregulated during the first 2 months after infection, and a shift to Th1 response with robust IFN-γ production was observed, which lasted until the end of the study. Th2 response (IL-4) was very weak during the course of this study. Upregulation of CCR9 after 6 months of infection was also observed. In conclusion, regulatory T cell response that occurs early after Map exposure is vigorous and infective dose dependent but short lived; it is then replaced by a strong Th1 response and interferon-gamma production, characteristic of subclinical JD.
Full-field quantum correlations of spatially entangled photons

description: Spatially entangled twin photons allow the study of high-dimensional entanglement, and the Laguerre-Gauss modes are the most commonly used basis to discretize the single photon mode spaces. In this basis, to date only the azimuthal degree of freedom has been investigated experimentally due to its fundamental and experimental simplicity. We show that the full spatial entanglement is indeed accessible experimentally, i.e., we have found practicable radial detection modes with negligible cross correlations. This allows us to demonstrate hybrid azimuthal -- radial quantum correlations in a Hilbert space with more than 100 dimensions per photon.

description: The spectral predictions of stellar population models are not as accurate in the ultra-violet (UV) as in the optical wavelength domain. One of the reasons is the lack of high-quality stellar libraries. The New Generation Stellar Library (NGSL), recently released,represents a significant step towards the improvement of this situation. To prepare NGSL for population synthesis, we determined the atmospheric parameters of its stars, we assessed the precision of the wavelength calibration and characterised its intrinsic resolution. We also measured the Galactic extinction for each of the NGSL stars. For our analyses we used ULySS, a full spectrum fitting package, fitting the NGSL spectra against the MILES interpolator. We find that the wavelength calibration is precise up to 0.1 px, after correcting a systematic effect in the optical range. The spectral resolution varies from 3Å in the UV to 10Å in the near-infrared (NIR), corresponding to a roughly constant reciprocal resolution R ~ 1000 and an instrumental velocity dispersion $σ_{ins}$ ~ 130 km/s. We derived the atmospheric parameters homogeneously. The precision for the FGK stars is 42K, 0.24 and 0.09 dex for Teff, logg and [Fe/H], respectively. The corresponding mean errors are 29K, 0.50 and 0.48 dex for theMstars, and for the OBA stars they are 4.5 percent, 0.44 and 0.18 dex. The comparison with the literature shows that our results are not biased.

Flatness is a Criterion for Selection of Maximizing Measures

description: For a full shift with Np+1 symbols and for a non-positive potential, locally proportional to the distance to one of N disjoint full shifts with p symbols, we prove that the equilibrium state converges as the temperature goes to 0. The main result is that the limit is a convex combination of the two ergodic measures with maximal entropy among maximizing measures and whose supports are the two shifts where the potential is the flattest. In particular, this is a hint to solve the open problem of selection, and this indicates that flatness is probably a/the criterion for selection as it was conjectured by A.O. Lopes. As a by product we get convergence of the eigenfunction at the log-scale to a unique calibrated subaction.
Dependence Deduction: A New Perspective in Constructing Matroidal Networks

description: Matroidal networks play a fundamental role in proving theoretical results on the limitation of network coding. This can be explained by the underlying connections between network coding and matroid theory. Two existing methods are known in the network coding literature for constructing networks from a matroid. The method due to Dougherty et al. has high time complexity but can create relatively simple network structures from a given matroid. The method due to El Rouayheb et al. has low time complexity, but results in rather complex network structures. This thesis studies the design of matroidal networks from uniform and whirl matroids, targeting both low time complexity and minimum network sizes. Our construction is based on the new technique of dependence deduction, which may serve as a promising direction for constructing general matroidal networks. Some of our constructions lead to new networks for understanding network coding in terms of base eld requirements.
Life After French Immersion: Grade 12 Students’ Perceptions of Continuing to Use French After Graduation

description: Many French Immersion (FI) graduates risk losing their French after high school, as many do not find local places where they can use it. Their disengagement with the French language in the years after graduation can be for various reasons. They often lack confidence in their ability to speak French and can be unaware of how the French that they acquired and used during the program can be deemed inadequate. The very nature of the FI context can be reason that these students acquire what can be viewed as a different variety of French. Discourses within FI can suggest that students do not consider themselves fully bilingual. Research has shown that full bilingualism is a rarity. Francophones in Canada are reluctant to accept Anglophones as legitimate speakers of French for a variety of reasons. Many FI graduates may struggle to use their French in the real world. This study aimed to understand Grade 12 FI student perceptions of continuing to use French after graduation. Results suggest that FI students have limited experience using their French outside of school. This creates a situation where they have little engagement with local Francophone populations. Most students lack confidence in using their French with Francophones. Encouraging FI students to gain experience speaking with Francophones outside of school before they graduate may increase the likelihood they will continue using their French after graduation.
How effectual will you be? Development and validation of a scale in higher education

description: The literature on effectual theory offers validated scales to measure effectual or causal logic in entrepreneurs' decision-making. However, there are no adequate scales to assess in advance the effectual or causal propensity of people with an entrepreneurial intention before the creation of their companies. We aim to determine the validity and reliability of an instrument to measure that propensity by first analysing those works that provide recognised validated scales with which to measure the effectual or causal logic in people who have already started up companies. Then, considering these scales, we designed a scale to evaluate the effectual or causal propensity in people who had not yet started up companies using a sample of 230 final-year business administration students to verify its reliability and validity. The validated scale has theoretical implications for the literature on potential entrepreneurship and entrepreneurial intention and practical implications for promoters of entrepreneurship who need to orient the behaviour of entrepreneurs, entrepreneurs of established businesses who want to implement a specific strategic orientation, entrepreneurs who want to evaluate the effectual propensity of their potential partners and workers, and academic institutions interested in orienting the entrepreneurial potential of their students.
