title: Learning English as a second language during childhood: A longitudinal case study
Creators: name: Cooze, Alysha
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Since the 1950s, hypotheses have been put forth to explain developmental behaviours observed during a learner’s second language (L2) acquisition. Many of these hypotheses build on language transfer, which provides a basis for the explanation of many phenomena that learners exhibit during the acquisition of their L2. However, aspects of transfer have yet to be fully understood; among others, how the critical period for language acquisition affects the relationship between a learner’s first language (L1) and L2 has yet to be unfolded. Transfer effects and the critical period are indeed potentially confounded when the L2 learner is a child. Furthermore, three questions surrounding transfer still remain. These questions are as follows: What is transferred? What are the conditions for transfer? And when does transfer occur? Further, while it is commonly observed that children are more proficient than adults at language learning, debates still exist as to whether or not a critical period for language acquisition exists at all. In relation to this, there is also the debate concerning whether children introduced to an L2 early in life behave more like a first or second language learner for that L2. This thesis describes a longitudinal corpus documenting a child named Nura, who is a L2 learner of English with Kazakh as her L1 (also with some passive knowledge of Chinese). More specifically, we focus on Nura’s development of singleton onsets and onset clusters which do not occur in her native Kazakh language. The data provides evidence for relatively immediate transfer effects through her early acquisition of her singleton onsets and onset clusters. However, the developmental patterns of a number of sounds and sound combinations also point to issues in child L2 development in contexts where transfer is not possible, if only for certain phonological dimensions of the L2.

description: We present supersymmetry breaking four dimensional orientifolds of type IIA strings. The compact space is a torus times a four dimensional orbifold. The orientifold group reflects one direction in each torus. RR tadpoles are cancelled by D6-branes intersecting at angles in the torus and in the orbifold. The angles are chosen such that supersymmetry is broken. The resulting four dimensional theories contain chiral fermions. The tadpole cancellation conditions imply that there are no non-abelian gauge anomalies. The models also contain anomaly-free U(1) factors.

description: Resilience has become one of the keywords in the recent scholarly and policy debates on food security. However, household resilience to food insecurity is unobservable ex ante. Therefore, the two key issues in empirical research and program implementation are how to estimate a proxy index of household resilience on the basis of observable variables and assess whether this index is a good indicator of the construct it intends to measure, i.e. household resilience. This paper contributes to this literature providing evidence based on two case studies: Tanzania and Uganda. Specifically, the paper: (i) proposes a method to estimate a resilience index and analyses what are the most important components of household resilience, (ii) tests whether the household resilience index is a good predictor of future food security status and food security recovery capacity after a shock, and (iii) explores how idiosyncratic and covariate shocks affects resilience and household food security. The analysis shows that: (i) in both countries adaptive capacity is the most important dimension contributing to household resilience, (ii) the resilience index positively influences future household food security status, decreases the probability of suffering a food security loss should a shock occur and speeds up the recovery after the loss occurrence, and (iii) shocks have a negative effect on food security and resilience contributes to reduce the negative impacts of these shocks, though this is not proven for self-reported and idiosyncratic shocks.

description: Persistent tension between low-redshift observations and the Cosmic Microwave Background radiation (CMB), in terms of two fundamental distance scales set by the sound horizon $r_d$ and the Hubble constant $H_0$, suggests new physics beyond the Standard Model or residual systematics. We examine recently updated distance calibrations from Cepheids, gravitational lensing time-delay observations, and the Tip of the Red Giant Branch. Calibrating the Baryon Acoustic Oscillations (BAO) and Type Ia supernovae with combinations of the distance indicators, we obtain a joint and self-consistent measurement of $H_0$ and $r_d$ at low redshift, independent of cosmological models and CMB inference. In an attempt to alleviate the tension between late-time and CMB-based measurements, we consider four extensions of the standard $Λ$CDM model. The sound horizon from our different measurements is $r_d=(137\pm3^{stat.}\pm2^{syst.})$~Mpc. Depending on the adopted distance indicators, the $combined$ tension in $H_0$ and $r_d$ ranges between 2.3 and 5.1 $σ$. We find that modifications of $Λ$CDM that change the physics after recombination fail to solve the problem, for the reason that they only resolve the tension in $H_0$, while the tension in $r_d$ remains unchanged. Pre-recombination extensions (with early dark energy or the effective number of neutrinos $\rm{N}_{\rm{eff}}=3.24 \pm 0.16$) are allowed by the data, unless the calibration from Cepheids is included. Results from time-delay lenses are consistent with those from distance-ladder calibrations and point to a discrepancy between absolute distance scales measured from the CMB (assuming the standard cosmological model) and late-time observations. New proposals to resolve this tension should be examined with respect to reconciling not only the Hubble constant but also the sound horizon derived from the CMB and other cosmological probes.

description: Biotic and abiotic conditions in the world’s oceans have changed considerably in the last two centuries as a result of anthropogenic factors, including whaling, sealing, fishing, and climate change. For species that have limited variation in life-history traits, life-history characteristics may impede the ability to adapt to changing environmental conditions. Albatrosses are one such group, where breeding investment is limited to a single egg every one or two years. At a coarse level, individuals may decide whether to breed or not, or whether to incubate an egg or not, but one of the only finer-scale adjustment in parental investment involves altering egg size, along with parental foraging and chick provisioning. We investigated changes in egg size in Atlantic Yellow-nosed Albatrosses (Thalassarche chlororhynchos) breeding at Tristan da Cunha, South Atlantic Ocean, from 1856 to 2015. We found no change in egg length, or breadth, which may suggest that with regards to this life-history parameter, Atlantic Yellow-nosed Albatrosses appear to have been able to buffer the effects of the trophic, climatic and oceanographic changes in the South Atlantic Ocean.

description: A high degree of heterogeneity has been observed amongst Irish beef farms, with a diverse range of production systems employing different practices and technologies. Such variation can compromise the estimates obtained when stochastic frontier analysis is used to estimate the frontier under which farms in the sector operate, since it relies on the assumption that all farms operate under the same technology. A latent class stochastic frontier model is implemented using an unbalanced panel dataset constructed from farm level data for Irish beef farms between the years 2000 and 2013, in order to identify different technologies. Results obtained suggest that a single frontier model overestimates technical inefficiency compared to the model where technology heterogeneity is taken into account. Overall results highlight the importance of correctly addressing technology heterogeneity in order to obtain reliable technical efficiency measures; and the comparison of the main characteristics for different classes identified suggest the need of targeted policy measures.

description: We define an operational notion of phases in interferometry for a quantum system undergoing a completely positive non-unitary evolution. This definition is based on the concepts of quantum measurement theory. The suitable generalization of the Pancharatnan connection allows us to determine the dynamical and geometrical parts of the total phase between two states linked by a completely positive map. These results reduce to the knonw expressions of total, dynamical and geometrical phases for pure and mixed states evolving unitarily.

description: Wheat is a key staple crop for global food security, but its production is strongly concentrated in a few regions, among which the EU is the first producer. EU farmers are struggling to keep high productivity levels due to global market and climate challenges. Risk management practices (RMP) are often advocated as viable tools to cope against these uncertainties, but their adoption can also subtract resources to the production activity, resulting in a controversial impact on the overall farm productivity. This paper analysis whether and how much four RMP contribute to wheat farming efficiency in France and Hungary using i) a stochastic frontier model to obtain a measure of farms efficiency; ii) an endogenous switching regression model to quantify the RMP impact. Results show that RMP can benefit farm efficiency, but not all the RMP have the same effect. While insurance, diversification and contract farming can positively affect farm efficiency, cultivating different varieties can reduce farm efficiency of about 10% depending on the production conditions.

description: Intelligent reflecting surface (IRS) has recently been envisioned to offer unprecedented massive multiple-input multiple-output (MIMO)-like gains by deploying large-scale and low-cost passive reflection elements. By adjusting the reflection coefficients, the IRS can change the phase shifts on the impinging electromagnetic waves so that it can smartly reconfigure the signal propagation environment and enhance the power of the desired received signal or suppress the interference signal. In this paper, we consider downlink multigroup multicast communication systems assisted by an IRS. We aim for maximizing the sum rate of all the multicasting groups by the joint optimization of the precoding matrix at the base station (BS) and the reflection coefficients at the IRS under both the power and unit-modulus constraint. To tackle this non-convex problem, we propose two efficient algorithms under the majorization--minimization (MM) algorithm framework. Specifically, a concave lower bound surrogate objective function of each user's rate has been derived firstly, based on which two sets of variables can be updated alternately by solving two corresponding second-order cone programming (SOCP) problems. Then, in order to reduce the computational complexity, we derive another concave lower bound function of each group's rate for each set of variables at every iteration, and obtain the closed-form solutions under these loose surrogate objective functions. Finally, the simulation results demonstrate the benefits in terms of the spectral and energy efficiency of the introduced IRS and the effectiveness in terms of the convergence and complexity of our proposed algorithms.

On the formation of massive stars

Year: 2002

description: We calculate numerically the collapse of slowly rotating, non-magnetic, massive molecular clumps, which conceivably could lead to the formation of massive stars. Because radiative acceleration on dust grains plays a critical role in the clump's dynamical evolution, we utilize a wavelength-dependent radiation transfer and a three component dust model: amorphous carbon particles, silicates and "dirty ice"-coated silicates. We do not spatially resolve the innermost regions of the molecular clump and assume that all material in the innermost grid cell accretes onto a single object. We introduce a semi-analytical scheme for augmenting existing evolution tracks of pre-main sequence protostars by including the effects of accretion. By considering an open outermost boundary, an arbitrary amount of material could, in principal, be accreted onto this central star. However, for the three cases considered (30, 60, and 120 solar masses originally within the computation grid), radiation acceleration limited the final masses to 31.6, 33.6, and 42.9 solar masses, respectively, for wavelength-dependent radiation transfer and to 19.1, 20.1, and 22.9 solar masses for comparison simulations with grey radiation transfer. We demonstrate that massive stars can in principle be formed via accretion through a disk. We conclude with the warning that a careful treatment of radiation transfer is a mandatory requirement for realistic simulations of the formation of massive stars.

description: We describe an approach for incorporating prior knowledge into machine learning algorithms. We aim at applications in physics and signal processing in which we know that certain operations must be embedded into the algorithm. Any operation that allows computation of a gradient or sub-gradient towards its inputs is suited for our framework. We derive a maximal error bound for deep nets that demonstrates that inclusion of prior knowledge results in its reduction. Furthermore, we also show experimentally that known operators reduce the number of free parameters. We apply this approach to various tasks ranging from CT image reconstruction over vessel segmentation to the derivation of previously unknown imaging algorithms. As such the concept is widely applicable for many researchers in physics, imaging, and signal processing. We assume that our analysis will support further investigation of known operators in other fields of physics, imaging, and signal processing.

description: Generalized trigonometric functions (GTFs) are simple generalization of the classical trigonometric functions. GTFs are deeply related to the $p$-Laplacian, which is known as a typical nonlinear differential operator. Compared to GTFs with one parameter, there are few applications of GTFs with two parameters to differential equations. We will apply GTFs with two parameters to studies on the inviscid primitive equations of oceanic and atmospheric dynamics, new formulas of Gaussian hypergeometric functions, and the $L^q$-Lyapunov inequality for the one-dimensional $p$-Laplacian.

On the basis of analyzing concept and characteristics of the forest experience, this paper analyzed current situation of forest experience by taking Kunming West Mountain Forest Park as an example. It found there are existing problems in subject image, development methods and degree, professional personnel and concept. In view of these problems, it came up with recommendations including determining subject image, designing special products, accelerating cultivation of professional personnel, and strengthening training of forest experience concept. It is expected to provide reference for multi-functional use theory of China and provide ideas for developing forest experience projects.

description: The study of zinc oxide, within the homogeneous electron gas approximation, results in overhybridization of zinc $3d$ shell with oxygen $2p$ shell, a problem shown for most transition metal chalcogenides. This problem can be partially overcome by using LDA+$U$ (or, GGA+$U$) methodology. However, in contrast to the zinc $3d$ orbital, Hubbard type correction is typically excluded for the oxygen $2p$ orbital. In this work, we provide results of electronic structure calculations of an oxygen vacancy in ZnO supercell from ab initio perspective, with two Hubbard type corrections, $U_{\mathrm{Zn}-3d}$ and $U_{\mathrm{O}-2p}$. The results of our numerical simulations clearly reveal that the account of $U_{\mathrm{O}-2p}$ has a significant impact on the properties of bulk ZnO, in particular the relaxed lattice constants, effective mass of charge carriers as well as the bandgap. For a set of validated values of $U_{\mathrm{Zn}-3d}$ and $U_{\mathrm{O}-2p}$ we demonstrate the appearance of a localized state associated with the oxygen vacancy positioned in the bandgap of the ZnO supercell. Our numerical findings suggest that the defect state is characterized by the highest overlap with the conduction band states as obtained in the calculations with no Hubbard-type correction included. We argue that the electronic density of the defect state is primarily determined by Zn atoms closest to the vacancy.

description: We have analysed images of the field of A2390 obtained with the CFHT and HST. The analysis fits models to bulge and disk components to several hundred galaxies, with about equal samples from the cluster and field. We also have assessed and graded asymmetries in the images. The cluster galaxies are compared in different cluster locations and also compared with field galaxies. We find that the central old population galaxies are bulge-dominated, while disk systems have young populations and are found predominantly in the outer cluster. S0 and bulgy disk galaxies are found throughout, but concentrate in regions of substructure. Disks of cluster blue galaxies are generally brighter and smaller than those in the field. We find that the cluster members have a higher proportion of interacting galaxies than the field sample. Interactions in the cluster and in the field, as well as cluster infall, appear to inhibit star-formation in galaxies.

Accretion bursts during the embedded phase of young protostars are probably most intense, but can only be inferred indirectly through long-wavelength observations. We perform radiative transfer calculations for young stellar objects (YSOs) formed in hydrodynamic simulations to predict the long wavelength, sub-mm and mm, flux responses to episodic accretion events, taking into account heating from the young protostar and from the interstellar radiation field. We find that the flux increase due to episodic accretion events is more prominent at sub-mm wavelengths than at mm wavelengths; e.g. a factor of ~570 increase in the luminosity of the young protostar leads to a flux increase of a factor of 47 at 250 micron but only a factor of 10 at 1.3 mm. Heating from the interstellar radiation field may reduce further the flux increase observed at longer wavelengths. We find that during FU Ori-type outbursts the bolometric temperature and luminosity may incorrectly classify a source as a more evolved YSO, due to a larger fraction of the radiation of the object being emitted at shorter wavelengths

Superbranes and Super Born-Infeld Theories as Nonlinear Realizations
Creators: name: Ivanov, E.
Publisher: name: arXiv
Year: 2001
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We outline, on a few instructive examples, the characteristic features of the approach to superbranes and super Born-Infeld theories based on the concept of partial spontaneous breaking of global supersymmetry (PBGS). The examples include the N=1, D=4 supermembrane and the ``space-filling'' D2- and D3-branes. Besides giving a short account of the available results for these systems, we present some new developments. For the supermembrane we prove the equivalence of the equation of motion following from the off-shell Goldstone superfield action and the one derived directly from the nonlinear realizations formalism. We give a new derivation of the off-shell Goldstone superfield actions for the considered systems, using a universal procedure inspired by the relationship between linear and nonlinear realizations of PBGS.

description: We study properties of the quantale spectrum Max A of an arbitrary unital C*-algebra A. In particular we show that the spatialization of Max A with respect to one of the notions of spatiality in the literature yields the locale of closed ideals of A when A is commutative. We study under general conditions functors with this property, in addition requiring that colimits be preserved, and we conclude in this case that the spectrum of A necessarily coincides with the locale of closed ideals of the commutative reflection of A. Finally, we address functorial properties of Max, namely studying (non-)preservation of limits and colimits. Although Max is not an equivalence of categories, therefore not providing a direct generalization of Gelfand duality to the noncommutative case, it is a faithful complete invariant of unital C*-algebras.

description: After a short review of recent progresses in 2D Euler equations with random initial conditions and noise, some of the recent results are improved by exploiting a priori estimates on the associated infinite dimensional Fokker-Planck equation. The regularity class of solutions investigated here does not allow energy- or enstrophy-type estimates, but only bounds in probability with respect to suitable distributions of the initial conditions. This is a remarkable application of Fokker-Planck equations in infinite dimensions. Among the example of random initial conditions we consider Gibbsian measures based on renormalized kinetic energy.

description: The capital structure of a firm is very important to the firm's successful operation. The objective of the study was to analyze the effects of Capital Structure on Corporate Performance of selected firms on the Nigerian Stock Exchange in Nigeria from 2011 to 2017. The study employed data from five multinational companies, using Micro Panel data as the estimated technique. Both the Random Effect Model and the Fixed Effect Model were estimated, and the Hausman effect was carried out to determine the appropriate model. The result shows that the effect of liquidity of the firms is negatively related to return on Asset (ROA). Hence, keeping funds in non-interest yielding form does not increase the ROA of the firms. Similarly, the short term debt financing (CLA) is negatively related to ROA. However, there is a positive relationship between long term debt financing and ROA. It noted that short term debt financing requires the payment of the debt in a short term, and this may not be convenient for the firms, and impair their performance. However, repaying long term debt may be convenient, and this may have a positive effect on the performance of the firms. Management of the quoted firms in Nigeria is strongly advised to increase the use of equity capital in financing to improve the earnings of their firms.

description: Approximate Nearest Neighbor Search (ANNS) is now widely used in various applications, ranging from information retrieval, question answering, and recommendation, to search for similar high-dimensional vectors. As the amount of vector data grows continuously, it becomes important to support updates to vector index, the enabling technique that allows for efficient and accurate ANNS on vectors. Because of the curse of high dimensionality, it is often costly to identify the right neighbors of a single new vector, a necessary process for index update. To amortize update costs, existing systems maintain a secondary index to accumulate updates, which are merged by the main index by global rebuilding the entire index periodically. However, this approach has high fluctuations of search latency and accuracy, not even to mention that it requires substantial resources and is extremely time-consuming for rebuilds. We introduce SPFresh, a system that supports in-place vector updates. At the heart of SPFresh is LIRE, a lightweight incremental rebalancing protocol to split vector partitions and reassign vectors in the nearby partitions to adapt to data distribution shift. LIRE achieves low-overhead vector updates by only reassigning vectors at the boundary between partitions, where in a high-quality vector index the amount of such vectors are deemed small. With LIRE, SPFresh provides superior query latency and accuracy to solutions based on global rebuild, with only 1% of DRAM and less than 10% cores needed at the peak compared to the state-of-the-art, in a billion scale vector index with 1% of daily vector update rate.

description: If there are large extra dimensions and the fundamental Planck scale is at the TeV scale, then the question arises of whether ultra-high energy cosmic rays might probe them. We study the neutrino-nucleon cross section in these models. The elastic forward scattering is analyzed in some detail, hoping to clarify earlier discussions. We also estimate the black hole production rate. We study energy loss from graviton mediated interactions and conclude that they can not explain the cosmic ray events above the GZK energy limit. However, these interactions could start horizontal air showers with characteristic profile and at a rate higher than in the Standard Model.
