What kind of language are L2 Spanish students learning? : a critical study on the relevance of relative clause explanations
Creators: name: Escudero, Alejandra
Publisher: name: University of British Columbia
Year: 2011

description: This is a critical study of how Spanish language textbooks present relative constructs at the post-secondary level. Specifically, do textbooks give information about what Spanish speakers actually say or do they simply prescribe usage patterns? Subordination through relative constructs (i.e., que [that, who], quien [who], lo que [that which], and so on) is one of the ways through which L2 Spanish learners begin to produce complex discourse (e.g., to clarify, to integrate, and to avoid repetition). Thus, these constructs deserve special attention. For this study, we reviewed the presentation of eleven relative constructs in 30 textbooks at the three different levels of language proficiency (beginner, intermediate and advanced) and then we compared them with occurrences in the Corpus de Referencia del Español Actual CREA (2008) [Reference Corpus of Current Spanish] electronic corpus of the Spanish language. Results showed that the relative construct que [that, who] presents the highest frequency in the electronic corpus, corroborating the information explained in the textbooks. For all other constructs, our analyses revealed great discrepancy between frequencies of appearance in the electronic corpus and the textbooks. For example, many textbook authors give great importance to the relative construct quien [who], when its use in actual discourse is much lower than expected. The analysis shows that textbooks give preference to specific relative constructs in a decontextualized setting. Results suggest that L2 Spanish students may be learning to speak in a pragmatically marginal style. Therefore, textbooks may be hindering full integration into a Hispanic community. The data collected from the electronic corpus suggest that Spanish speakers are replacing the relative constructs with other constructs when communicating in Spanish. Some relative constructs are less frequent than the grammars lead us to believe.
Ab initio probing of the electronic band structure and Fermi surface of fluorine-doped WO3 as a novel low-TC superconductor

description: First-principles calculations were performed to investigate the electronic structure and the Fermi surface of the newly discovered low-temperature superconductor: fluorine-doped WO3. We find that F doping provides the transition of the insulating tungsten trioxide into a metallic-like phase WO3-xFx, where the near-Fermi states are formed mainly from W 5d with admixture of O 2p orbitals. The cooperative effect of fluorine additives in WO3 consists in change of electronic concentration as well as the lattice constant. At probing their influence on the near-Fermi states separately, the dominant role of the electronic factor for the transition of tungsten oxyfluoride into superconducting state was established. The volume of the Fermi surface gradually increases with the increase of the doping. In the sequence WO3 \rightarrow WO2.5F0.5 the effective atomic charges of W and O ions decrease, but much less, than it is predicted within the idealized ionic model - owing to presence of the covalent interactions W-O and W-F.

description: Keberadaan lebih dari 500 industri dan pemukiman untuk kurang lebih 5 juta penduduk yang menghasilkan sekitar 200 ton limbah perharinya dibuang ke sungai Citarum tanpa melalui proses instalasi pengolahan air limbah (IPAL), merupakan sumber utama dari pencemaran sungai Citarum. Upaya pemerintah terhadap Citarum telah dilakukan selama 5 tahun dalam berbagai bentuk program, namun hasilnya belum signifikan. Salah satu kendala dalam program, untuk menanggulangi pencemaran air sungai Citarum adalah tidak ada data informasi yang menunjukan tingkat pencemaran dan lokasi pencemaran. Untuk mengatasi kendala tersebut, diperlukan sebuah sistem yang mampu melakukan pembacaan secara terus menerus dan menentukan lokasi yang diindentifikasi sebagai sumber pencemaran. Sistem yang dibangun untuk mendeteksi pencemaran dan lokasi pencemaran berbasis IoT dan klasifikasi naive bayes. Metode naive bayes dipilih karena dalam teknik data mining yang menerapkan teori Bayes dalam klasifikasi dengan asumsi yang sangat kuat (naif) akan independensi dari masing-masing kondisi kejadian. Hasil penelitian menunjukkan penggunaan metode klasifikasi naive bayes pada proses klasifikasi pencemaran air sungai memiliki tingkat akurasi sebesar 96%. Hasil ini dapat diterima untuk akurasi klasifikasi.

Publisher: name: Zenodo
Year: 2019
Subjects: OpenUP interim report

description: This report aims to provide a methodology to construct and present a taxonomy that links innovative channels of dissemination with alternative or open metrics. The taxonomy we will construct provides orientation for scholars who intend to make use of these channels. The taxonomy is also useful for scholars who want/need to assess or reflect about their usage. Based on the considerations of the sociology of valuation, we came up with different dimensions that constitute relevant dimensions, e.g., discourses, cultural (field specific) practices, and metrics. We provide the following approach to translate and enrich these theoretical concepts with empirical analysis conducted within OpenUp.

description: We discuss as a fundamental characteristic of orthogonal polynomials like the existence of a Lie algebra behind them, can be added to their other relevant aspects. At the basis of the complete framework for orthogonal polynomials we put thus --in addition to differential equations, recurrence relations, Hilbert spaces and square integrable functions-- Lie algebra theory. We start here from the square integrable functions on the open connected subset of the real line whose bases are related to orthogonal polynomials. All these one-dimensional continuous spaces allow, besides the standard uncountable basis ${|x>}$, for an alternative countable basis ${|n>}$. The matrix elements that relate these two bases are essentially the orthogonal polynomials: Hermite polynomials for the line and Laguerre and Legendre polynomials for the half-line and the line interval, respectively. Differential recurrence relations of orthogonal polynomials allow us to realize that they determine a unitary representation of a non-compact Lie algebra, whose second order Casimir ${\cal C}$ gives rise to the second order differential equation that defines the corresponding family of orthogonal polynomials. Thus, the Weyl-Heisenberg algebra $h(1)$ with ${\cal C}=0$ for Hermite polynomials and $su(1,1)$ with ${\cal C}=-1/4$ for Laguerre and Legendre polynomials are obtained. Starting from the orthogonal polynomials the Lie algebra is extended both to the whole space of the ${\cal L}^2$ functions and to the corresponding Universal Enveloping Algebra and transformation group. Generalized coherent states from each vector in the space ${\cal L}^2$ and, in particular, generalized coherent polynomials are thus obtained.

description: Variability in neurobiological signatures is ubiquitous in early life but the link to adverse developmental milestones in humans is unknown. We examined how levels of signal and noise in movement signatures during the 1st year of life constrain early development in 71 healthy typically developing infants, either at High or Low familial Risk (HR or LR, respectively) for developing Autism Spectrum Disorders (ASD). Delays in early learning developmental trajectories in HR infants (validated in an analysis of 1,445 infants from representative inf﻿ant-sibling studies) were predicted by worse stochastic patterns in their spontaneous head movements as early as 1–2 months after birth, relative to HR infants who showed more rapid developmental progress, as well as relative to all LR infants. While LR 1–2 mo-old infants’ movements were significantly different during a language listening task compared to during sleep, HR infants’ movements were more similar during both conditions, a striking lack of diversity that reveals context-inflexible experience of ambient information. Contrary to expectation, it is not the level of variability per se that is particularly detrimental in early life. Rather, inflexible sensorimotor systems and/or atypical transition between behavioral states may interfere with the establishment of capacity to extract structure and important cues from sensory input at birth, preceding and contributing to an atypical brain developmental trajectory in toddlerhood.

description: Nowadays, search engines are used to find various information on the Web. Search engines that are implied traditional search based on keywords do not always provide relevant information. Meanwhile by semantic search can provide relevant results because it can understand the meaning of the context and its connection. One approach to semantic search is to use ontology. Ontology is used to define concepts and relevant relations in a domain. In Information Retrieval (IR), an ontology encompasses in returning relevant information from a collection of unstructured information. One application of ontology in IR is query expansion. In this research, The query entered by the users will be searched for its relation to the ontology domain which will be expanded later. We use tourism in Bandung Raya as an ontology domain. The search in this research is represented by using Vector Space Model (VSM). Furthermore, relevant documents from search result will be provided to users. Based on the results of testing, the system that is built is able to provide relevant information with an average MAP value better than the search system that only uses traditional search methods.

description: The global behaviour of the normal function associated with van Geemen's family of lines on the mirror quintic is studied. Based on the associated inhomogeneous Picard-Fuchs equation, the series expansions around large complex structure, conifold, and around the open string discriminant are obtained. The monodromies are explicitly calculated from this data and checked to be integral. The limiting value of the normal function at large complex structure is an irrational number expressible in terms of the di-logarithm.

description: This work presents a formalization of the theorem of existence of most general unifiers in first-order signatures in the higher-order proof assistant PVS. The distinguishing feature of this formalization is that it remains close to the textbook proofs that are based on proving the correctness of the well-known Robinson's first-order unification algorithm. The formalization was applied inside a PVS development for term rewriting systems that provides a complete formalization of the Knuth-Bendix Critical Pair theorem, among other relevant theorems of the theory of rewriting. In addition, the formalization methodology has been proved of practical use in order to verify the correctness of unification algorithms in the style of the original Robinson's unification algorithm.

Our results show that the critical temperature increases as a function of $B$ at $μ=0$, but for values $μ$ larger than about 210-225 MeV, the opposite behavior is realized. As the magnetic field increases, the critical point $(T^*,μ^*)$ moves from large $μ$, small $T$ towards small $μ$, larger $T$ in the $μ$--$T$ phase diagram.

Aspects of the progressive in English and Icelandic
Creators: name: Johannsdottir, Kristin M.
Publisher: name: University of British Columbia
Year: 2011

description: This dissertation presents a semantic analysis of the progressive of both English and Icelandic, the only two Germanic languages that generally are considered to have fully grammaticalized progressive constructions. The progressive is an aspectual category where the focus is on a single, dynamic event being in progress at a certain time – the reference time. It is generally considered to be a sub-category of the imperfective aspect, just like the habitual aspect, and one of the descriptions typically given for the progressive is that it cannot have a habitual reading. Similarly, stative predicates are categorized as imperfective but non-progressive. Nevertheless, both habitual sentences and stative predicates occur in the progressive; they then appear to have a slightly different meaning from the one they have when they occur in the simple past/present. I argue that the subtle meaning difference between progressive and non-progressive statives and habituals is in fact an implicature. Stative verbs are shifted to being events in order to take on one or more of the prototypical eventive properties, and as events they can occur in the progressive. In such cases they usually imply dynamicity, control and/or temporariness. Habituals are essentially stative so when they occur in the progressive they too have been shifted to events, resulting in the same implicature of prototypical eventive properties, particularly temporariness. We then get the reading that the habit is temporary and it contrasts with the simple past/present that picks out a more general habit. Additionally I investigate another way to indicate that a series of events is in progress, namely the present participle progressive in Icelandic, which is a progressive construction with a presupposition for pluractionality. It usually occurs with iterative adverbials, in particular adverbs of quantity, which give additional information on the frequency of the series of events.

description: Demographic growth, changes in diet, and reliance on first-generation biofuels are increasing the human demand for agricultural products, thereby enhancing the human pressure on global freshwater resources. Recent research on the food-water nexus has highlighted how some major agricultural regions of the world lack the water resources required to sustain current growth trends in crop production. To meet the increasing need for agricultural commodities with limited water resources, the water use efficiency of the agricultural sector must be improved. In this regard, recent work indicates that the often overlooked strategy of changing the crop distribution within presently cultivated areas offers promise. Here we investigate the extent to which water in the United States could be saved while improving yields simply by replacing the existing crops with more suitable ones. We propose crop replacement criteria that achieve this goal while preserving crop diversity, economic value, nitrogen fixation, and food protein production. We find that in the United States, these criteria would greatly improve calorie (+46%) and protein (+34%) production and economic value (+208%), with 5% water savings with respect to the present crop distribution. Interestingly, greater water savings could be achieved in water-stressed agricultural regions of the US such as California (56% water savings), and other western states.

description: The phase relations in boron have been investigated at high pressure and high temperature using a multianvil apparatus, and the quenched sample has been analyzed by x-ray diffraction, Raman spectra and transmission electron microscopy. We demonstrate that γ-B28 can be synthesized over a wide P-T range, and T-B50 is obtained at higher temperatures and similar pressures. The phase boundary of the β-B106, γ-B28 and T-B50 is determined at pressures between 7 and 18 GPa and the temperatures of 500-2200 °C. The results suggest that T-B50 might be an intermediate phase-metastable, formed for kinetic reasons (Ostwald rule) on the way from β-B106 to T-192 and γ-B28 to T-192.

description: We explore the energetics of the titular reaction, which current astrochemical databases consider to be open at typical dense molecular (i.e., dark) cloud conditions. As is common for reactions involving the transfer of light particles, we assume that there are no intersystem crossings of the potential energy surfaces involved. In the absence of any such crossings, we find that this reaction is endoergic and will be suppressed at dark cloud temperatures. Updating accordingly a generic astrochemical model for dark clouds changes the predicted gas-phase abundances of 224 species by greater than a factor of 2. Of these species, 43 have been observed in the interstellar medium. Our findings demonstrate the astrochemical importance of determining the role of intersystem crossings, if any, in the titular reaction.

description: A failure of adaptive inference—misinterpreting available sensory information for appropriate perception and action—is at the heart of clinical manifestations of schizophrenia, implicating key subcortical structures in the brain including the hippocampus. We used high resolution, three-dimensional (3D) fractal geometry analysis to study subtle and potentially biologically relevant structural alterations (in the geometry of protrusions, gyri and indentations, sulci) in subcortical gray matter (GM) in patients with schizophrenia relative to healthy individuals. In particular, we focus on utilizing Fractal Dimension (FD), a compact shape descriptor that can be computed using inputs with irregular (i.e., not necessarily smooth) surfaces in order to quantify complexity (of geometrical properties and configurations of structures across spatial scales) of subcortical GM in this disorder. Probabilistic (entropy-based) information FD was computed based on the box-counting approach for each of the seven subcortical structures, bilaterally, as well as the brainstem from high-resolution magnetic resonance (MR) images in chronic patients with schizophrenia (n = 19) and age matched healthy controls (n = 19) (age ranges: patients, 22.7–54.3 and healthy controls, 24.9–51.6 years old). We found a significant reduction of FD in the left hippocampus (median: 2.1460, range: 2.07–2.18 vs. median: 2.1730, range: 2.15–2.23, p<0.001; Cohen’s effect size, U3 = 0.8158 (95% Confidence Intervals, CIs: 0.6316, 1.0)), the right hippocampus (median: 2.1430, range: 2.05–2.19 vs. median: 2.1760, range: 2.12–2.21, p = 0.004; U3 = 0.8421 (CIs: 0.5263, 1)), as well as left thalamus (median: 2.4230, range: 2.40–2.44, p = 0.005; U3 = 0.7895 (CIs: 0.5789, 0.9473)) in schizophrenia patients, relative to healthy individuals. Our findings provide in-vivo quantitative evidence for reduced surface complexity of hippocampus, with reduced FD indicating a less complex, less regular GM surface detected in schizophrenia.

description: Changes in the structure of the BINAP framework were shown to provide improved enantioselectivities in asymmetric reactions. This dissertation describes two novel modifications of the BINAP scaffold and their implications in asymmetric reactions. Two BINAP derivatives containing 3,3'-substituents bound to the binaphthalene core via a C-C bond have been prepared. The syntheses of (S)-3,3 '-bis(phenethyl)­BINAP and (S)-3,3 '-bis(phenoxymethyl)-BINAP hinged on the successful ortho­lithiation and iodine incorporation at the I-position of 2-(diphenylphosphinoyl)-3-phenyethyny 1 naphthalene. Electronically similar (S)-BINAP and (S)-3,3 '-bis(phenethyl)-BINAP were compared in Rh- and Pd-catalyzed asymmetric reactions. It was concluded that levels of asymmetric induction and product enantiosense reversals can be attributed solely to a change in the steric properties of the BINAP ligand used. Isosteric yet electronically different (S)-3,3 '-bis(phenethyl)-, (S)-3,3 '-bis(phenoxymethyl)- and (S)-3,3 '-(OBnh­BINAP in the same reactions afforded mixed results. This indicated that the nature of the 3,3 '-substituent, not necessarily the cr-basicity of the ligand, might dictate asymmetric induction and product enantiosense. A series of 3,3 '-disubstituted xy!BINAP derivatives were prepared by combining strategies employed in the syntheses of xy!BINAP and 3,3 '-substituted BIN AP ligands. The use of a naproxen ether-based auxiliary allowed for biaryl axis resolution and access to diastereomeric 3,3 '-disubstituted xy!BINAP derivatives. Auxiliary cleavage and further manipulation of a bisnaphthol intermediate afforded 3,3 '-(OiPr)2-xylBINAP and 3,3 '-(OPiv)2-xylBINAP. 3,3 '-disubstituted xylBINAP derivatives were used in Rh- and Pd-catalyzed asymmetric reactions. The effect of 3 ,3 '-disubstitution and the 3 ,5-dialkyl meta effect are cooperative in the Pd-catalyzed arylation of 2,3-dihydrofuran and the Rh-catalyzed hydrogenation of MAC. The naproxen ether-substituted xylBINAP derivatives outperformed all other 3,3 '-substituted BINAP and xylBINAP ligands, with the naproxen and P-xylyl substituents being necessary for high levels of asymmetric induction. The reversal of product enantiosense observed in Rh-catalyzed hydrogenations upon 3,3'-substitution of the BINAP scaffold was further investigated. The energies of the catalyst-substrate complexes involved in the Rh-catalyzed hydrogenation of MAC obtained from OFT calculations were consistent with an anti-lock-and-key mode of enantioselection. Temperature and pressure studies, as well as quadrant diagram analyses indicate that a change in the kinetics of olefin could be responsible for the enantiosense reversals and high levels of asymmetric induction observed with 3,3 '-disubsituted BINAP and xylBINAP ligands.

description: In addiction, there are few human studies on the neural basis of cue‐induced changes in value‐based decision making (Pavlovian‐to‐instrumental transfer, PIT). It is especially unclear whether neural alterations related to PIT are due to the physiological effects of substance abuse or rather related to learning processes and/or other etiological factors related to addiction. We have thus investigated whether neural activation patterns during a PIT task help to distinguish subjects with gambling disorder (GD), a nonsubstance‐based addiction, from healthy controls (HCs). Thirty GD and 30 HC subjects completed an affective decision‐making task in a functional magnetic resonance imaging (fMRI) scanner. Gambling‐associated and other emotional cues were shown in the background during the task. Data collection and feature modeling focused on a network of nucleus accumbens (NAcc), amygdala, and orbitofrontal cortex (OFC) (derived from PIT and substance use disorder [SUD] studies). We built and tested a linear classifier based on these multivariate neural PIT signatures. GD subjects showed stronger PIT than HC subjects. Classification based on neural PIT signatures yielded a significant area under the receiver operating curve (AUC‐ROC) (0.70, p = 0.013). GD subjects showed stronger PIT‐related functional connectivity between NAcc and amygdala elicited by gambling cues, as well as between amygdala and OFC elicited by negative and positive cues. HC and GD subjects were thus distinguishable by PIT‐related neural signatures including amygdala–NAcc–OFC functional connectivity. Neural PIT alterations in addictive disorders might not depend on the physiological effect of a substance of abuse but on related learning processes or even innate neural traits.
Consequences of Flooding on Spectral Statistics

description: We study spectral statistics in systems with a mixed phase space, in which regions of regular and chaotic motion coexist. Increasing their density of states, we observe a transition of the level-spacing distribution P(s) from Berry-Robnik to Wigner statistics, although the underlying classical phase-space structure and the effective Planck constant remain unchanged. This transition is induced by flooding, i.e., the disappearance of regular states due to increasing regular-to-chaotic couplings. We account for this effect by a flooding-improved Berry-Robnik distribution, in which an effectively reduced size of the regular island enters. To additionally describe power-law level repulsion at small spacings, we extend this prediction by explicitly considering the tunneling couplings between regular and chaotic states. This results in a flooding- and tunneling-improved Berry-Robnik distribution which is in excellent agreement with numerical data.

The black/white wealth gap : the transgenerational effects of post-reconstruction sharecropping and racial systems on African Americans today
Creators: name: Chandra, Michelle Veena
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to investigate how sharecropping systems, a form of racialized agriculture, instituted in the Post-Reconstruction era has had a profound impact on the inability of many African Americans to generate and pass down wealth to successive generations lending to the sizable gap in wealth between whites and blacks (as well as between blacks) in America today. Another aim was to find out how systematic anti-black racism, particularly during Jim Crow, aided in denying a substantial number of southern blacks from entering into the labour market and engaging in the white American ideal of property ownership by re-asserting a white hegemonic order reminiscent of the antebellum period. Another objective was to trace the effects of the Great Migration (1910-1970), the northward and westward migration of close to 8 million blacks out of the South, that occurred as a result of this systemic racism. It was found that the late move of black men out of agriculture and into other areas of the labour market, in addition to the persistent racism that upheld sharecropping systems in the South, severely hampered the ability of many African Americans from building and passing down wealth holdings to their children, helping to explain some of the staggering wealth discrepancies that we see today. Furthermore, the results of the study indicated that some blacks, particularly in Durham, North Carolina, benefited by the anti-black racism in the South by creating a black clientele in predominantly black neighbourhoods where whites did not want to set up shop, allowing some blacks entry into the coveted middle class. The effects of the Great Migration did not benefit all, however, in that it also created clusters of blacks in northern urban areas who faced increasing anti-black racism and exclusion from the marketplace, lending to the creation of a lower middle class and an impoverished underclass. The principle conclusion was that in order to understand present day inequalities among African Americans, there must be a historical analysis that is sensitive to the transgenerational effects of sharecropping, Jim Crow and institutionalized racism.
