How young children negotiate sociomathematical norms during inquiry-based learning in mathematics : a discursive psychological perspective.
Creators: name: McLellan, Sylvia Susan
Publisher: name: University of British Columbia
Year: 2014

description: This dissertation uses a discursive psychological perspective to investigate how young children use the structure of spoken language to support their participation in mathematical discussion. There is a general consensus that participation in the practice of collective argumentation not only promotes, but actually constitutes the learning of mathematics (Cobb, Yackel & Wood, 1992a; Krummheuer, 2007). However, given the wide variety of forms that mathematical communication might take (Barwell, Leung, Morgan & Street, 2005), how to fruitfully define and document the practices of communication involved, especially for young learners, remains an open question. Through a series of related discourse analyses (three linked studies carried out on a common data set), I explore some of the discursive practices 5- to 7-year-olds use as they negotiate what will become a taken-as-shared understanding regarding mathematical validity: a sociomathematical norm regarding what it means to know in mathematics. Discursive psychology (Edwards, 1997) affords an examination of how participants treat notions of knowing and understanding during interaction. Using corpus linguistic analysis in the first study here allows me to elaborate features of this group’s culture of negotiation by illuminating patterns in the interactional sequences involving doing knowing. Conversation analysis in the second study affords an examination of the practices by which young children incorporate mathematical content within the social act of negotiation: doing mathematical understanding. Further analysis attending to multimodal aspects of communication in the third study shows how the participants used those previously noted discursive practices to develop and sustain a six week long investigation into the meaning of the square root symbol: doing algebraic reasoning. These analyses show how the children are able to draw upon a range of sociomathematical norms as resources that enable them to participate in ways that co-ordinate with each other. The findings suggest that expanding our expectations for what mathematical knowing looks like with young children affords the development of learning environments that support all children’s sustained, successful engagement with mathematics.

description: Companies invest in research and development (R&D) to safeguard their competitive ability and increase productivity. Using extensive company data for Germany, the study shows that manufacturing companies that engage in R&D activities and that are located in a central urban agglomeration are especially productive. They additionally benefit from knowledge created by R&D activities of other companies and public research. However, the regional research systems in major urban regions are very different. These differences require tailored support by research and technology policy for the development of regional research and innovation systems on a region-by-region basis. The goal should be to reinforce the regional transfer of knowledge among companies, universities, and non-university research institutes. Regional differences must be taken into account when devising policy because uniform programs on the federal level will have different effects depending on the research region.

description: Fairtrade certification is intended to improve both the income and living conditions of producers, thereby creating more fairness in international trade. However, theoretical considerations and empirical studies show that this goal is only achieved to a limited extent, at least for coffee: Faitrade certification leads at best to small increases in income for coffee farmers. The results on the reduction of income volatility, payments used to implement social projects, and improved access to credit are also mixed. Fairtrade is a means of market segmentation for roasters and retailers.

description: In May, the EU Commission presented its proposal for the EU budget for 2021 to 2027—a period of change for the EU. Not only will Great Britain’s exit from the Union leave a significant hole in the budget, but at the same time the budget must cover a vast range of additional requirements. Current international policy developments are already demanding the EU acting as a community, and the European project will continue to require a high level of investment. For managing this balancing act expenditure cuts in traditional areas are indispensable. But the Commission’s lopsided proposal relies on higher revenue. Currently, the Commission is planning fund allocations in the absence of a policy strategy for the years after 2020.

description: We study the relationship between local and global error in Runge-Kutta methods for initial-value problems in ordinary differential equations. We show that local error control by means of local extrapolation does not equate to global error control. Our analysis shows that the global error of the higher-order solution is propagated under iteration, and this can cause an uncontrolled increase in the global error of the lower-order solution. We find conditions under which global error control occurs during the initial stages of the RK integration, but even in such a case the global error is likely to eventually exceed the user-defined tolerance.

description: Earnings differences are a recurring topic of public discussion in Germany. Data from the long-term Socio-Economic Panel (SOEP) study as well as a separate survey of German employees (LINOS) show that earnings inequalities are generally perceived as fair while a substantial share of the respondents find the current earnings distribution in Germany unfair. This applies above all to the middle and lower end of the earnings distribution, where respondents perceive there to be particularly severe underpayment. More rarely do respondents find that employees earning high salaries are unfairly overpaid. Perceived unfairness in the upper strata of the earnings distribution is associated with a reduction in effort at the workplace while perceived unfairness in the lower end of the earnings distribution is accompanied by a lack of participation in the democratic process.

description: We extend previous analyses of wide-angle correlations in the galaxy power spectrum in redshift space to include all general relativistic effects. These general relativistic corrections to the standard approach become important on large scales and at high redshifts, and they lead to new terms in the wide-angle correlations. We show that in principle the new terms can produce corrections of nearly 10 % on Gpc scales over the usual Newtonian approximation. General relativistic corrections will be important for future large-volume surveys such as SKA and Euclid, although the problem of cosmic variance will present a challenge in observing this.

description: To actively address maternal morbidity and mortality in Mexico, proficiency among obstetrics and gynecology (OBGYN) residents in the surgical management of postpartum hemorrhage (PPH) is a priority. However, the capacity of programs to provide this training is unknown. The self-reported knowledge, education, and proficiency of common surgical techniques for the management of PPH among OBGYN residents in Mexico was evaluated. Educational resources, perceived barriers to acquiring skills, and clinical decision-making were explored. In July of 2018, an anonymous electronic survey was sent to 86 residents at four hospitals throughout Mexico. Surgical techniques queried included uterine tamponade (UT), uterine compression sutures (UCS), uterine devascularization (UD), hypogastric artery ligation (HAL), and gravid hysterectomy (HT). Participants also answered case-based questions about a patient with PPH. The survey response rate was 59.3% (51/86). Seventy-nine percent of residents reported understanding the rationale and techniques for the surgical intervention of PPH. However, 43.9% reported limited ability to perform these procedures with autonomy. Eighty-six percent of residents reported exposure to these techniques while performing a rescue procedure during PPH and 49% reported learning these procedures while performing prophylactic techniques in patients without PPH. Only 25.5% had been exposed to simulation training. Lack of a training module for these skills in their curriculum was noted by 74.5%. The majority of the participants chose UCS, UD, HAL, and HT as the first, second, third, and fourth rescue procedures to perform for PPH, respectively. Most residents reported theoretical knowledge of surgical interventions for PPH, but their self-rated ability to independently perform such skills and a curriculum focused on PPH management was suboptimal.

description: We investigate the coupling of the electromagnetic sources (charge and current densities) to the scalar and vector potentials in classical electrodynamics, using Green function techniques. As is well known, the scalar potential shows an action-at-a-distance behavior in Coulomb gauge. The conundrum generated by the instantaneous interaction has intrigued physicists for a long time. Starting from the differential equations that couple the sources to the potentials, we here show in a concise derivation, using the retarded Green function, how the instantaneous interaction cancels in the calculation of the electric field. The time derivative of a specific additional term in the vector potential, present only in Coulomb gauge, yields a supplementary contribution to the electric field which cancels the gradient of the instantaneous Coulomb gauge scalar potential, as required by gauge invariance. This completely eliminates the contribution of the instantaneous interaction from the electric field. It turns out that a careful formulation of the retarded Green function, inspired by field theory, is required in order to correctly treat boundary terms in partial integrations. Finally, compact integral representations are derived for the Lienard-Wiechert potentials (scalar and vector) in Coulomb gauge which manifestly contain two compensating action-at-a-distance terms.

A retrospective analysis of all feto-maternal demographic and biometric data in fetuses with normal estimated fetal weight (EFW) and a CPR examination between the years 2014–2019, in a university medical center. The study group included healthy singleton pregnancies from 32-week gestation, with an examination-to-delivery interval of <31 days. The three models compared two thresholds: <5th percentile (CPR 1, CPR 3) and <10th percentile (CPR2). The CPR1 and CPR2 models both use local CPR reference ranges, while the CPR3 model uses an external CPR reference range. The main outcome was predictive accuracy for urgent cesarean delivery (CD), operative delivery (OD), and composite outcome (CO), defined as an Apgar score of <7, fetal blood pH Overall, 410 low-risk pregnancies with normal weight fetuses were enrolled in the study. All three CPR models turned out to be significant predictors of CD, with an odds ratio (OR) of 9, 95% CI (2.7–27), p p p p p p A CPR model based on local reference ranges and <5th percentile cutoffs showed the highest PPV for CD and OD. The calculation of local references for CPR should be encouraged.

Hydrologic processes in unsaturated waste rock piles in the Canadian subarctic
Creators: name: Momeyer, Steven Alexander
Publisher: name: University of British Columbia
Year: 2014

description: Hydrologic processes occurring within waste rock situated in a semi-arid continuous permafrost environment at the Diavik Diamond Mine waste rock research project, located in Northwest Territories, Canada, were studied. Characterization of water flow through, and hydrologic properties of, waste rock is complicated by the heterogeneous clast composition, the spatial arrangement of these clasts, internal structures, and the unsaturated nature. Results are presented from experiments on six active zone lysimeters (AZLs), each with an approximate 5 cubic metre volume, along with three instrumented test piles, each with an approximate 3,000 square metre footprint and approximate 15 metre height. A basal drain collection system and individual basal collection lysimeters underlie each test pile to monitor water discharge. The test piles and AZLs were instrumented with monitoring devices designed to collect geochemical, thermal and hydrological data including moisture content, pore-water samples, pore-gas samples, temperature, thermal conductivity, air permeability, matric potential, and microbiology samples. Results indicate that infiltration into the waste rock was dependent on the magnitude and timing of rainfall. Rainfall received after net radiation peaked in June permitted greater infiltration. Once infiltrated, water flow through the matrix was observed to be the dominate transport mechanism under average rainfall conditions despite a grain size distribution with less than 18% of the waste rock composed of the finer than 5-mm fraction. Only in response to large storm events was water flow through preferential flow paths observed. Continuous monitoring of water discharge at the base of the test piles indicated the rate of initial wetting front advancement under average precipitation was about 7.5 m.yr-¹ and under drier conditions was about 6 m.yr-¹. Based on solute transport determined from a tracer test at the AZLs, the average advective velocity during the active flow period was between 1.0 and 1.4 m.yr-¹. Through the first three years of study, the active layer of the uncovered test piles extended the entire depth of the pile, although frozen areas within the core may remain. Each year the discharge period was shorter and less pile volume thaws, consistent with an overall cooling of the lower central core of the test piles.
Oral second primary tumour risk predictors : clinical factors and loss of heterozygosity
Creators: name: Prelec, Jelena
Publisher: name: University of British Columbia
Year: 2014

description: Oral squamous cell carcinoma (SCC) has a poor survival rate mainly due to late stage diagnosis and the high risk of developing second primary tumours (SPTs). Risk factors associated with progression of primary oral premalignant lesions (OPLs) to SCC have been validated; however, little research has been done on the risk predictors of SPTs. The objective of this thesis was to identify the demographic, clinicopathological and molecular risk factors associated with oral SPTs as well as those associated with second oral premalignant lesion (SOPL) progression to an oral SPT. From a cohort of the Oral Cancer Prediction Longitudinal study, data collected included: 1) demographic and habit information; 2) primary tumour information; 3) clinicopathological features during follow-up; and 4) toluidine blue (TB) and florescence visualization results. SOPL biopsy samples were analyzed for loss of heterozygosity (LOH) at regions previously identified as high risk for primary OPL progression. Of 296 patients who were followed-up subsequent to curative primary tumour treatment, 23 (8%) developed SPTs. Sixty-seven (23%) patients developed SOPLs, of which nine (14.5%) progressed to SPTs. Patients with primary tumours located on low-risk sites had an increased risk of SPTs (P=0.004) and SOPLs (P=0.009). Tobacco (P=0.046) and alcohol consumption (P=0.019) were each associated with the presence of SOPLs. The presence of an SOPL was associated with risk for SPT development, independent from histopathological diagnosis (P<0.001). TB was not only effective in identifying SPT development but was a valuable tool for predicting SOPL risk of progression to an SPT. Additionally, the majority of SOPLs had an LOH on at least one of the three chromosomal arms (9p, 3p and17p). The results suggest it is necessary to increase surveillance, to roughly six years following treatment in order to improve on the early detection of SOPLs and address the risk factors for SPTs. Data also supports the need to routinely biopsy SOPLs in order to provide a timely diagnosis and provide samples for the analysis of LOH. Ultimately translating this knowledge to the clinical management of patients has the potential to identify patients who are at high-risk for SPTs and improve long-term survival rates.

description: We develop from basic economic principles a continuous-time model for a large investor who trades with a finite number of market makers at their utility indifference prices. In this model, the market makers compete with their quotes for the investor's orders and trade among themselves to attain Pareto optimal allocations. We first consider the case of simple strategies and then, in analogy to the construction of stochastic integrals, investigate the transition to general continuous dynamics. As a result, we show that the model's evolution can be described by a nonlinear stochastic differential equation for the market makers' expected utilities.

description: We investigated the arcuate artery blood flow in the region of the abnormally localized placenta in women who had undergone insertion of an obstetric pessary and were receiving micronized progesterone. The study included 120 pregnant women with high perinatal risks and abnormal placental localization. The patients were randomized to receive the Arabin’s pessary and vaginal micronized progesterone (Group A, n = 60) or vaginal micronized progesterone only (Group B, n = 60). Randomization was carried based on the order of hospital admission: odd patient numbers were allocated to Group A and even numbers to Group B. Patients underwent a series of ultrasound scans to evaluate the placental migration and presence of abnormal placental attachment. Depending on the results of the scan, study participants were divided into the following groups: (1) patients without placental migration: A1 (n = 23) and B1 (n = 42); and (2) patients with placental migration: A2 (n = 37) and B2 (n = 18). Women in subgroups A1 and B1 were further divided into the subgroups based on the presence of abnormal placental attachment: A1x (n = 5) and B1x (n = 12) with abnormal placental attachment; and A1O (n = 18) and B1O (n = 30) without the abnormal placental attachment. In patients with abnormal placental attachment, the resistance of blood flow in the arcuate arteries was significantly higher than in those with normal placental attachment. A significant increase in the blood flow resistance occurred between 24 and 28 weeks of gestation. The combined use of the obstetric pessary and vaginal micronized progesterone in women with abnormal placental localization helped maintain the resistivity index at low levels and reduce the rate of abnormal placental attachment by 1.3-fold (OR 0.694 (95% CI: 0.21–2.29)).

description: Intuitionistic logic, in which the double negation law not-not-P = P fails, is dominant in categorical logic, notably in topos theory. This paper follows a different direction in which double negation does hold. The algebraic notions of effect algebra/module that emerged in theoretical physics form the cornerstone. It is shown that under mild conditions on a category, its maps of the form X -> 1+1 carry such effect module structure, and can be used as predicates. Predicates are identified in many different situations, and capture for instance ordinary subsets, fuzzy predicates in a probabilistic setting, idempotents in a ring, and effects (positive elements below the unit) in a C*-algebra or Hilbert space. In quantum foundations the duality between states and effects plays an important role. It appears here in the form of an adjunction, where we use maps 1 -> X as states. For such a state s and a predicate p, the validity probability s |= p is defined, as an abstract Born rule. It captures many forms of (Boolean or probabilistic) validity known from the literature. Measurement from quantum mechanics is formalised categorically in terms of `instruments', using Lüders rule in the quantum case. These instruments are special maps associated with predicates (more generally, with tests), which perform the act of measurement and may have a side-effect that disturbs the system under observation. This abstract description of side-effects is one of the main achievements of the current approach. It is shown that in the special case of C*-algebras, side-effect appear exclusively in the non-commutative case. Also, these instruments are used for test operators in a dynamic logic that can be used for reasoning about quantum programs/protocols. The paper describes four successive assumptions, towards a categorical axiomatisation of quantitative logic for probabilistic and quantum systems.

description: We prove a version of quantum geometric Langlands conjecture in characteristic $p$. Namely, we construct an equivalence of certain localizations of derived categories of twisted crystalline $\mathcal D$-modules on the stack of rank $N$ vector bundles on an algebraic curve $C$ in characteristic $p$. The twisting parameters are related in the way predicted by the conjecture, and are assumed to be irrational (i.e., not in $\mathbb F_p$). We thus extend the results of arXiv:math/0602255 concerning the similar problem for the usual (non-quantum) geometric Langlands. In the course of the proof, we introduce a generalization of $p$-curvature for line bundles with non-flat connections, define quantum analogs of Hecke functors in characteristic $p$ and construct a Liouville vector field on the space of de Rham local systems on $C$.

description: To evaluate associations between operative vaginal delivery complications and provider experience (operative vaginal delivery volume and time since residency). We included all operative vaginal deliveries between 2008 and 2014 at a tertiary care teaching hospital, stratified into forceps-assisted and vacuum-assisted deliveries. Complications included severe perineal lacerations (3rd and 4th degree) and neonatal injuries (subgaleal/subdural/cerebral hemorrhage, facial nerve injury, and scalp injury), which were identified by International Classification Diagnosis-9 codes. Providers were categorized by operative vaginal delivery volume (mean annual forceps- or vacuum-assisted deliveries over the study interval) and time since residency. Regression analyses were used to compare complication rates by provider volume and time since residency, adjusting for potential confounders, using 0–1 deliveries per year and <5 years since residency as reference groups. Nine hundred and thirty-four forceps and 1074 vacuums occurred. For forceps-assisted deliveries, severe perineal injury was decreased among providers with >10 forceps per year (aOR 0.50 [95%CI 0.30–0.81]) and at 15–19 years (aOR 0.45 [95% CI 0.22–0.94], and ≥25 years (aOR 0.45 [0.27–0.73]) since residency. There were no associations with neonatal injuries. Among vacuum-assisted deliveries, severe perineal injury decreased at ≥25 years since residency (aOR 0.35 [95%CI 0.17–0.74], with no association with provider volume. Neonatal injury decreased at 5–9 years (aOR 0.53 [95%CI 0.30–0.93]), and 15–19 years since residency (aOR 0.53 [95%CI 0.29–0.97]), due to differences in scalp injuries. Neonatal injuries other than scalp injury were rare. Severe perineal lacerations decreased with increasing operative vaginal delivery experience, primarily among forceps-assisted vaginal delivery. Providers >5 years since residency may have lower scalp injury with vacuums, but this cohort was largely underpowered for neonatal injury.

description: We study $k$-divisible partition structures, which are families of random set partitions whose block sizes are divisible by an integer $k=1,2,\ldots$. In this setting, exchangeability corresponds to the usual invariance under relabeling by arbitrary permutations; however, for $k>1$, the ordinary deletion maps on partitions no longer preserve divisibility, and so a random deletion procedure is needed to obtain a partition structure. We describe explicit Chinese restaurant-type seating rules for generating families of exchangeable $k$-divisible partitions that are consistent under random deletion. We further introduce the notion of {\em Markovian partition structures}, which are ensembles of exchangeable Markov chains on $k$-divisible partitions that are consistent under a random process of {\em Markovian deletion}. The Markov chains we study are reversible and refine the class of Markov chains introduced in {\em J.\ Appl.\ Probab.}~{\bf48}(3):778--791.

description: Objective: To evaluate the predictive value of local versus external cerebroplacental ratio (CPR) reference ranges for delivery outcomes in low-risk pregnancies. Methods: A retrospective analysis of all feto-maternal demographic and biometric data in fetuses with normal estimated fetal weight (EFW) and a CPR examination between the years 2014–2019, in a university medical center. The study group included healthy singleton pregnancies from 32-week gestation, with an examination-to-delivery interval of <31 days. The three models compared two thresholds: <5th percentile (CPR 1, CPR 3) and <10th percentile (CPR2). The CPR1 and CPR2 models both use local CPR reference ranges, while the CPR3 model uses an external CPR reference range. The main outcome was predictive accuracy for urgent cesarean delivery (CD), operative delivery (OD), and composite outcome (CO), defined as an Apgar score of <7, fetal blood pH Results: Overall, 410 low-risk pregnancies with normal weight fetuses were enrolled in the study. All three CPR models turned out to be significant predictors of CD, with an odds ratio (OR) of 9, 95% CI (2.7–27), p p p p p p Conclusions: A CPR model based on local reference ranges and <5th percentile cutoffs showed the highest PPV for CD and OD. The calculation of local references for CPR should be encouraged.

description: Because of the 3D nature of galaxies, an algorithm for constructing spatial density distribution models of galaxies on the basis of galaxy images has many advantages over surface density distribution approximations. We present a method for deriving spatial structure and overall parameters of galaxies from images and estimate its accuracy and derived parameter degeneracies on a sample of idealised model galaxies. The test galaxies consist of a disc-like component and a spheroidal component with varying proportions and properties. Both components are assumed to be axially symmetric and coplanar. We simulate these test galaxies as if observed in the SDSS project through ugriz filters, thus gaining a set of realistically imperfect images of galaxies with known intrinsic properties. These artificial SDSS galaxies were thereafter remodelled by approximating the surface brightness distribution with a 2D projection of a bulge+disc spatial distribution model and the restored parameters were compared to the initial ones. Down to the r-band limiting magnitude 18, errors of the restored integral luminosities and colour indices remain within 0.05 mag and errors of the luminosities of individual components within 0.2 mag. Accuracy of the restored bulge-to-disc ratios (B/D) is within 40% in most cases, and becomes worse for galaxies with low B/D, but the general balance between bulges and discs is not shifted systematically. Assuming that the intrinsic disc axial ratio is < 0.3, the inclination angles can be estimated with errors < 5deg for most of the galaxies with B/D < 2 and with errors < 15deg up to B/D = 6. Errors of the recovered sizes of the galactic components are below 10% in most cases. In general, models of disc components are more accurate than models of spheroidal components for geometrical reasons.
