description: In this thesis, the design of a supermarket is parametrically explored to reduce the energy consumption from these high energy consuming buildings. Starting with a model which is representative of supermarkets in Calgary, Alberta, Canada a number of parameters (insulation, lighting, windows, phase change material, greenroofing, building integrated photovoltaics, etc) are individually investigated to determine the impact on energy consumption. A model is found to have 30% reduction in building loads before a greenhouse is added to the design to reduce the dependency on transportation and external sources. A new set of parameters are investigated in the greenhouse (window assemblies, shading devices, night-time insulation, semi-transparent photovoltaics, etc) to reduce the energy consumption of the new Complex (supermarket and greenhouse). It is shown that such a Complex can exist with similar performance as a supermarket on its own. Finally, by optimizing the mechanical systems and utilizing cold outside air, energy consumption can be reduced by an additional 20% to achieve a net-zero energy design with the use of rooftop situated building integrated photovoltaics and semi-transparent photovoltaics in the greenhouse. In the end, and through the use of building strategies explored in this thesis, a reduction of 240 tonnes of GHG emissions are avoided through the application of this design.
Comments on the N=1 SU(M+p)xSU(p) quiver gauge theory with flavor

description: We study supersymmetric vacua of the N=1 cascading SU(M+p)xSU(p) gauge theory with flavor - the theory on p D3-branes and M wrapped D5-branes at the tip of the conifold, and N_f flavor D7-branes wrapping a holomorphic four-cycle inside the conifold. The Coulomb branch of the moduli space is inherited from the pure gauge theory without flavor and was thoroughly studied in the past. Besides, there is a Higgs branch where some D3 and/or D5-branes dissolve in the D7-branes forming the worldvolume gauge instantons. We study the Higgs branch both from the field theory and the bulk point of view. On the classical level the moduli space is closely related to the one of the N=2 C^2/Z_2 orbifold theory, in particular certain vacua of the N=1 theory are related to noncommutative instantons on the resolved C^2/Z_2. On the quantum level the Higgs branch acquires corrections due to renormalization of the Kahler potential and non-perturbative effects in field theory. In the bulk this is encoded in the classical D7-brane geometry. We compute the VEVs of the protected operators and the field theory RG flow and find an agreement with the parallel computations in the bulk.

Dislocation core field. I. Modeling in anisotropic linear elasticity theory

Year: 2011
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Aside from the Volterra field, dislocations create a core field, which can be modeled in linear anisotropic elasticity theory with force and dislocation dipoles. We derive an expression of the elastic energy of a dislocation taking full account of its core field and show that no cross term exists between the Volterra and the core fields. We also obtain the contribution of the core field to the dislocation interaction energy with an external stress, thus showing that dislocation can interact with a pressure. The additional force that derives from this core field contribution is proportional to the gradient of the applied stress. Such a supplementary force on dislocations may be important in high stress gradient regions, such as close to a crack tip or in a dislocation pile-up.

description: The ratio of the shear viscosity ($η$) to entropy density ($s$) for the intermediate energy heavy-ion collisions has been calculated by using the Green-Kubo method in the framework of the quantum molecular dynamics model. The theoretical curve of $η/s$ as a function of the incident energy for the head-on Au+Au collisions displays that a minimum region of $η/s$ has been approached at higher incident energies, where the minimum $η/s$ value is about 7 times Kovtun-Son- Starinets (KSS) bound (1/4$π$). We argue that the onset of minimum $η/s$ region at higher incident energies corresponds to the nuclear liquid gas phase transition in nuclear multifragmentation.

description: One of Canada’s trademarks is the cultural diversity of its people, and how different ways of life are integrated to Canadian society a current and important issue. Often, unresolved dilemmas surface as attempts to negotiate and recognize different cultural identities in ways that reflect both immigrants and Canadian preferences. Therapy conversations can become spaces in which immigrant family members, together with therapists, collaborate in recognizing each other according to cultural memberships that are preferred by them. In this study, I focus on how immigrant family members relationally recognize and co-articulate with each other their preferred cultural memberships. I also explore what immigrant family members consider therapists’ helpful conversational moves in helping them negotiate preferred cultural identities. Informed by discursive psychology, I offer my analysis of five immigrant families’ therapy conversations. I describe three practices (resisting recognition, foregrounding cultural identities, and recognizing preferred cultural identities) in which immigrant family members engaged, together with their therapists, in successfully negotiating preferred cultural identities. This preference-animated research can be useful for family therapists who work with immigrant families, to help them foreground relational patterns of dis-preferred cultural identity ascriptions (i.e., misrecognition), to find relational patterns that suit them better as a family.

description: Short-term and long-term compression behavior of single proppant grains were thoroughly studied by diametrical compression tests and DEM/FEM simulations. Hydroprop showed the highest single grain crush-resistance while ceramic proppant grains with coarse surfaces were susceptible to creep behavior under load. One-dimensional compression tests under various stress levels and temporal conditions were systematically carried out to investigate the time-independent and time-dependent crushing behavior of proppant grain packs. Baylic Sand was the most crushing-prone whereas the OxSteel was the least. Most proppants showed creep behavior under long-term compression. Rock-proppant interaction tests were also performed which cast light on the proppant crushing and embedment under the field conditions. Pressure gradients of proppant-water slurries flowing through a small-diameter pipe were experimentally investigated and mimicked by DEM-CFD simulations. A generalized Darcy-Weisbach equation was proposed for the prediction of pressure gradients.

description: The aim of this research is to use a novel approach with less technical and analytic limitations in liquid solvent-bitumen diffusion studies. Taylor dispersion technique has been selected in this work due to its convenient short run-time experiments and reliable data analysis to find molecular diffusion coefficients in hexane-bitumen system. For the first time, the infinite dilution molecular diffusion coefficients of bitumen in hexane were measured in both cases of presence and relative absence of asphaltene particles in the solution. As the first result, polydisperse nature of bitumen is clearly revealed. Results were compared with common predictive tools and the most reliable correlation is proposed. Also, it is found that asphaltene particles presumably have surface charge in hexane solvent. Moreover, through concentration dependency investigations it was found that the molecular diffusion coefficients monotonically decrease as the viscosity of mixture increases within the concentration range studied. In conclusion, Taylor dispersion technique showed a great potential in diffusion studies of liquid solvent-bitumen systems.

description: Objectives: Sulforaphane, a major ingredient isolated from Brassica oleracea var. italica (broccoli), is known to exhibit anti-inflammatory, anti-cancer, and anti-diabetic effects. In this study, we employed an in vitro model of phorbol 12-myristate 13-acetate and a23187 (PMACI)-stimulated human mast cells (HMC-1 cells) to investigate the anti-allergic inflammatory effects and mechanisms of sulforaphane and Brassica oleracea var. italica extracts. Methods: Cytokine levels were measured by ELISA and quantitative real-time-PCR methods. Caspase-1 activity was determined by caspase-1 assay. Binding mode of sulforaphane within caspase-1 was determined by molecular docking simulation. Protein expression was determined by Western blotting. Results: Water extract of Brassica oleracea var. italica (WE) significantly reduced thymic stromal lymphopoietin (TSLP) secretion and caspase-1 activity on activated HMC-1 cells. In the molecular docking simulation and in vitro caspase-1 assays, sulforaphane regulated caspase-1 activity by docking with the identical binding site of caspase-1. Sulforaphane significantly inhibited the levels of inflammatory mediators including TSLP, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-8 in a dose-dependent manner. Immunoblotting experiments revealed that sulforaphane and WE reduced translocation of NF-κBp65 into the nucleus and phosphorylation of IκBα in the cytosol. Furthermore, phosphorylation of mitogen-activated protein kinases (MAPK) was down-regulated by treatment with sulforaphane or WE. Conclusion: Our findings suggest that sulforaphane and WE have anti-allergic inflammatory effects by intercepting caspase-1/NF-κB/MAPKs signaling pathways.
Modeling Storage and Flow of Fluids in Shale Reservoirs

description: Recent development of shale gas reservoirs has led to a revolution in the global energy market. The shale gas industry has expanded rapidly through the application of new drilling and completion technologies, particularly horizontal wells completed in multiple hydraulic fracture stages. While these technologies play a critical role enabling economical production from these resources, uncertainty in the understanding of basic shale gas reservoir properties, and methods used to characterize them, has led to inefficiencies in shale gas resource development. This thesis addresses uncertainties in the characterization of fluid storage and transport mechanisms in shales, and uses new methods for characterization in exploring enhanced recovery options for shale-hosted hydrocarbons. The primary gas storage mechanisms in organic-rich shales are free gas storage and adsorption; however, there is a significant amount of uncertainty in modeling these storage mechanisms in shale. Of the adsorption models tested, the simplified local density (SLD) model was found to be the most useful for shale gas storage estimation. The model was used not only for adsorption modeling, but also to rigorously correct free gas storage calculations for the presence of adsorbed phase volume. Further, the SLD model was used to predict changes in fluid behaviour within the confined pore space of shale reservoirs. An important contribution of this thesis is the estimation of gas storage and transport parameters from shale reservoir drill cuttings. Low-pressure (N2 and CO2) adsorption data was collected on “artificial” (crushed rock) shale cuttings, and used, in combination with the SLD model to predict high-pressure/high-temperature adsorption of hydrocarbons. Further, adsorption rate data, collected on small masses of artificial cuttings, combined with sophisticated numerical modeling which takes into account the physics of gas storage and transport through shale, was used to estimate shale gas diffusivity/permeability. Finally, the importance of hydrocarbon adsorption and diffusivity for predicting hydrocarbon liquid recovery after CO2 injection was investigated. A history-matched (flowback data) multi-fractured horizontal well completed in a tight liquid-rich reservoir was used as a starting point for sensitivities using CO2 injection. Unique to this study, fluid compositions as a function of depth in the reservoir were available. Simulation of CO2 huff-n-puff schemes using this calibrated model demonstrated that inclusion of adsorption/diffusion effects has an important impact on hydrocarbon liquid recovery.
Déu i el mal en la teologia de Martí Luter

description: En el pensament de Luter la qüestió del mal no es planteja ni discuteix en els termes de la teodicea i especulació filosòfica, sinó en el marc d’una teologia guiada exclusivament per la Paraula de Déu. En l’antropologia del teòleg de Wittenberg la fe, guiada sempre per l’Escriptura és la categoria fonamental. És aquesta fe i no les obres que justifiquen l’home. La fe juga també un paper decisiu en aquell que ha caigut en pecat, de tal manera que la mateixa fe i confiança en el Déu bondadós el fa aixecar i li perdona el pecat comès. Per Luter cal distingir dos camps on es planteja el problema de mal: un seria el mal moral o pecat derivat de la voluntat humana, i l’altre seria el mal que no depèn de la decisió humana, el mal físic i material. La presència del mal i els sofriments que comporta no poden ser mai una causa per abandonar la fe, sinó una ocasió única per viure-la amb més fervor. En el mateix mal, el creient hi veu la mà de Déu que el crida a creure més fermament, malgrat totes les aparences

description: Accretion-powered X-ray pulsars exhibit significant variability of the Cyclotron Resonance Scattering Feature (CRSF) centroid energy on pulse-to-pulse timescales, and also on much longer timescales. Two types of spectral variability are observed. For sources in group 1, the CRSF energy is negatively correlated with the variable source luminosity, and for sources in group 2, the opposite behavior is observed. The physical basis for this bimodal behavior is currently not understood. We explore the hypothesis that the accretion dynamics in the group 1 sources is dominated by radiation pressure near the stellar surface, and that Coulomb interactions decelerate the gas to rest in the group 2 sources. We derive a new expression for the critical luminosity such that radiation pressure decelerates the matter to rest in the supercritical sources. The formula for the critical luminosity is evaluated for 5 sources, using the maximum value of the CRSF centroid energy to estimate the surface magnetic field strength. The results confirm that the group 1 sources are supercritical and the group 2 sources are subcritical, although the situation is less clear for those highly variable sources that cross over the critical line. We also explain the variation of the CRSF energy with luminosity as a consequence of the variation of the characteristic emission height. The sign of the height variation is opposite in the supercritical and subcritical cases, hence creating the observed bimodal behavior.

description: Divergent natural selection is a major cause of phenotypic differentiation among populations exploiting different environments, but information on the ecological factors contributing to peak shift is largely missing from natural populations. Threespine stickleback (Gasterosteus aculeatus) is an emerging vertebrate model for studying phenotype-environment associations, as ancestral marine populations have adapted independently to postglacial freshwater environments. I characterized antipredator, foraging, and body shape phenotypes of 800+ fish from 16 ecologically diverse sites on the Alaska Peninsula. Gill rakers, antipredator traits, and body shape significantly associated with lake ecology, whereas foraging traits and body shape were influenced by geography. Stickleback from lakes ecologically similar to the ancestral state were more phenotypically similar to marine-influenced populations than fish from ecologically divergent habitats (i.e., small lakes). My study elucidates mechanisms associated with adaptive evolution and is one of relatively few that links ecological features of the adaptive landscape with phenotypic evolution in multiple populations.

description: Dermacentor albipictus is an important parasite of moose and other ungulate species. In 1989, winter ticks were reported as far north as 62° N, but recent anecdotal reports of clinically affected moose in the Sahtu Settlement Area, NT suggested significant range expansion. This research aimed to determine the occurrence of D. albipictus on moose and caribou hides from the Sahtu submitted by local hunters, to investigate growth and development of winter ticks on captive reindeer, and to develop a serological assay to detect antibodies to ticks using cattle as a model. Winter ticks were confirmed in 5 of 30 moose at 66° N. The development of ticks on captive reindeer was similar to that reported in moose. There was no consistent pattern in antibody response after exposure to ticks. Future studies should continue monitoring to understand the potential risks of this parasite to infest caribou under a changing climate.
Interception and Analysis of WCDMA Signals

description: Intercepting wireless signal has been of a great interest for law enforcement and military users as it provides precious information about illegal activity or the enemy intention. To intercept the signal, first, the signal existence must be detected. In case of using the spread spectrum, signal detection becomes more challenging since the spread spectrum system could bury the signal below the noise level to hide it. Therefore, a detection system that detects the signal existence even in a low signal to noise ratio (SNR) regime is needed to detect the hidden signal. In the unintended reception scenario, moreover, the receiver does not have any prior knowledge about the signal activity or the detection environment. Hence, the detection system should also operate without any prior knowledge about signal activity in the targeted frequency band or the signal statistics. This thesis develops an algorithm that utilizes the cyclostationary detector to detect the signal in low SNR regime. Furthermore, the cyclic frequency mismatch concept is used to determine the existence of the signal without any prior assumption about the signal activity. The bootstrap technique is then used to determine the threshold of the algorithm regardless of the noise distribution. To prove the applicability in real time situation, the proposed algorithm is implemented on the SoC FPGA Xilinx board. The research in this thesis offers the potentials of enhancing the detection performance while reducing the complexity of achieving this enhancement. The numerical results vali- date the efficacy of the proposed detection system in improving the detection performance compared to its counterparts. Finally, the FPGA implementation validates its applicability in real-world usage.

description: We present magnetic characterization of a binary rare-earth intermetallic compound Er5Si3, crystallizing in Mn5Si3-type hexagonal structure, through magnetization, heat-capacity, electrical resistivity, and magnetoresistance measurements. Our investigations confirm that the compound exhibits two magnetic transitions with decreasing temperature, first one at 35 K and the second one at 15 K. The present results reveal that the second magnetic transition is a disorder-broadened first-order transition, as shown by thermal hysteresis in the measured data. Another important finding is that, below 15 K, there is a magnetic-field-induced transition with a hysteretic effect with the electrical resistance getting unusually enhanced at this transition and the magnetorsistance (MR) is found to exhibit intriguing magnetic-field dependence indicating novel magnetic phase-co-existence phenomenon. It thus appears that this compound is characterized by interesting magnetic anomalies in the temperature-magnetic-field phase diagram.

description: Stereoscopic Particle Image Velocimetry measurements were taken in the turbulent wake of two dimensional rectangular cylinders. The influence of post-stall angles of attack and Reynolds number on the flow behind a thin flat plate, and for the normal case, the effect of thickness to chord (t/d) ratio over a family of rectangular cylinders were investigated. At all cases, quasi-periodic vortex shedding is observed, the normal direction Reynolds stress becomes very large just downstream of the mean recirculation zone, and the spanwise motions were uncorrelated to the main vortex shedding process. The data were processed to obtain the mean velocities, Reynolds stresses, and forces on the body. All terms in the turbulent kinetic energy equations were measured with the exception of dissipation which was found by difference. The pressure-related terms were estimated from the numerical solution of the Poisson equation for the instantaneous velocity field. Proper Orthogonal Decomposition modes are related via mean-field theory to construct generalized phase-averaging and low-order models capturing coherent cycle-to-cycle variations. The advection, production and pressure diffusion were all significant and mostly coherent. It is shown that high, average, and low amplitude vortex shedding cycles are different in terms of vortex street dimensions, vortex topology, circulation, and decay rate. It is also shown that these flows experience irregular significant decreases in the shedding amplitude associated with shedding of disorganized vortices in a large wake. Reynolds number was found to have imperceptible effects on the wake of a normal thin plate. A reduction in the angle of attack caused the wake to decrease in size and increase in shedding frequency but the global characteristics vary non-linearly. An increase in thickness from thin plate (t/d=0.05), caused the wake to shrink, low cycles to diminish, and local turbulence increase to a peak at t/d=1.0, identified as a critical thickness. At t/d=1.9, however, turbulent quantities decrease, the wake grows larger and significant cycle-to-cycle variations in the flow reports of a new vortex formation process.

description: We analyze possible interpretations of the recent LHCb evidence for CP violation in D meson decays in terms of physics beyond the Standard Model. On general grounds, models in which the primary source of flavor violation is linked to the breaking of chiral symmetry (left-right flavor mixing) are natural candidates to explain this effect, via enhanced chromomagnetic operators. In the case of supersymmetric models, we identify two motivated scenarios: disoriented A-terms and split families. These structures predict other non-standard signals, such as nuclear EDMs close to their present bounds and, possibly, tiny but visible deviations in K and B physics, or even sizable flavor-violating processes involving the top quark or the stops. Some of these connections, especially the one with nuclear EDMs, hold beyond supersymmetry, as illustrated with the help of prototype non-supersymmetric models.

description: Introduction
 This study was conducted to compare the pick-up rates of head and neck malignancies, duration of symptoms prior to first presentation to hospital and duration to commence treatment among newly diagnosed patients with head and neck malignancy during the COVID-19 pandemic. Methodology
 This cohort retrospective study includes newly diagnosed patients aged above 18 with head and neck malignancies based on histopathological diagnosis from January 2019 till December 2020.Descriptive analysis was performed and using SPSS, quantitative data was analyzed with t-test and qualitative data analyzed with Chi-square test. p value of less than .05 was considered statistically significant. Results
 There was a significant drop of 56.1% in the total number of new referrals from 12,371 in 2019 to 5,425 in 2020 (p= .00001). The pick-up rate for the number of cancer cases based on the overall new referrals increased from 0.27% to 0.39%. The duration to seek the first consultation from the time of symptom appearance had shorten with 23.8% of the patients coming within 1 month of symptoms as compared to 12.1% in 2019. More patients began definitive treatment within a month with 66.7% in 2020 as compared to 51.5% in 2019. Discussion/Conclusion
 COVID-19, has resulted cancer patients to begin definitive treatment within a month of diagnosis as a result of reduced patient load, by having an earlier imaging, biopsy and appointment dates at respective Oncology centers.Strategic measures taken (i.e. having an isolated scope room & scoping patients at predetermined time) has improved the cancer pick-up rates while ensuring the safety of healthcare providers.

A Simple Framework for the Dynamic Response of Cirrus Clouds to Local Diabatic Radiative Heating

description: This paper presents a simple analytical framework for the dynamic response of cirrus to a local radiative flux convergence, expressible in terms of three independent modes of cloud evolution. Horizontally narrow and tenuous clouds within a stable environment adjust to radiative heating by ascending gradually across isentropes while spreading sufficiently fast so as to keep isentropic surfaces nearly flat. More optically dense clouds experience very concentrated heating, and if they are also very broad, they develop a convecting mixed layer. Along isentropic spreading still occurs, but in the form of turbulent density currents rather than laminar flows. A third adjustment mode relates to evaporation, which erodes cloudy air as it lofts. The dominant mode is determined from two dimensionless numbers, whose predictive power is shown in comparisons with high resolution numerical cloud simulations. The power and simplicity of the approach hints that fast, sub-grid scale radiative-dynamic atmospheric interactions might be efficiently parameterized within slower, coarse-grid climate models.

description: María Zambrano creía que el título El hombre y lo divino podría ser no solo de un libro suyo sino de toda su obra. Con una particular sensibilidad para la dimensión mistérica o «trascendente del hombre», que es algo distinto del acierto con que se exprese después esa dimensión, ese libro y esa autora pueden ser hoy una buena introducción al hecho religioso para el hombre de nuestra sociedad secular. Esa dimensión trascendente, el ser humano la padece (porque le revela que él no es Dios) y, por otro lado, le abre a la esperanza. Desde aquí elabora una antropología y unas reflexiones sobre la Ilustración, la muerte de Dios, o el amor… en las que entra también una lúcida crítica al hombre europeo. El artículo intenta exponer esas reflexiones, señalando lo que (70 años después) habría que añadirles: la atención a la religiosidad india y a la teología de la liberación.

description: This thesis presents a comprehensive study of the pyrolysis of lignocellulosic biomass (sawdust, wheat, oat, flax and barley straws). In the first part of the study, the pyrolysis of sawdust was observed using a thermogravimetric analyzer (TGA), in order to understand the devolatilization process and to obtain its global kinetic parameters. The influences of particle size, initial weight of the sample and heating rate on the devolatilization of sawdust particles were assessed. It was observed that the pyrolysis of sawdust differed significantly with variations in heating rate. As the heating rate increased, the char yield also increased. The kinetic parameters, including activation energy (E), frequency factor (k0) and order of reaction (n), for the two stages considered in the model were: EA2 = 79.53 (kJ/mol), EA3 = 60.71 (kJ/mol); k02 = 1.90 × 106 (1/min), k03 = 1.01 × 103 (1/min); n2 = 0.91, n3 = 1.78, respectively. In the second part of the study, the pyrolysis of several Canadian straw biomasses was studied using a TGA and a bench-scale horizontal fixed-bed reactor. The effects of various catalysts on product yields are discussed. When using zeolite catalysts, the bio-oil and bio-char yields of the straw pyrolysis increased to 46.44% and 38.77%, respectively, while the gas yield was decreased to 13.65%. The use of the catalyst zeolite ZY-SS had the most significant effect on overall bio-oil and bio-char yields, increasing the bio-oil yield by about 2% and the bio-char yield by 8%. A screening of different catalysts unveiled that Ni-Mo/TiO2 was the most active catalyst. The structure was investigated using Brunauer-Emmett-Teller (BET) surface area showed that the Ni-Mo/TiO2 catalyst presented a higher surface area and more optimal mesopores than Ni-V/TiO2. Based on the results, it appears that the significant hydrodeoxygenation (HDO) activity for both the catalysts attributed to a high dispersion of metals and acidic sites, which was affected by the interaction between the nickel and the titania support. The activation energy (E) values for guaiacol reactions over Ni-Mo/TiO2 and Ni-V/TiO2 were 93.6 and 98.4 kj/mol, respectively; and, the E values for anisole reactions over Ni-Mo/TiO2 and Ni-V/TiO2 were 80.9 and 53.9 kj/mol, respectively.

China's Role in Africa: The Case of Sudan

description: The People’s Republic of China started to rebuild and strengthen its role as a regional superpower in the 1980’s after the first decades of so called irrelevant existence. Economic problems, poverty, and the lack of international partners plagued the country and continued when it was in close partnership with the Soviet Union until the 1960’s. Its hegemonicambitions emerged early in the face of international aid and prosperous credits. Until the end of the 1970’s, these tools were used to convince partners that it was worth for them to support China against the Soviet Union in the growing ideological debates. After Mao’s death and after getting over the detrimental consequences of the last years of his rule China required new and upgraded partnerships andreal economic connections.

The story of the new and economically improved China is now well known and does not need to be retold here. What is important is that China has come to occupy a particularly prominent position also in Africa. It is part of the new forces that help shape the continent. The main reason that Africa has become so prominent in Chinese foreign policy is its hunger for resources. The huge continent made up of several countries with enormous resource reserves is a perfect place for them to do business. This paper focuses on China’s role in the Sudan. Based on the experience of the Sino-Sudanese connections, it tries at the end to reflect more broadly on the Asian state’s Africa policy.

description: Temporal communities result from a consistent partitioning of nodes across multiple snapshots of an evolving complex network that can help uncover how dense clusters in a network emerge, combine, split and decay with time. Current methods for finding communities in a single snapshot are not straightforwardly generalizable to finding temporal communities since the quality functions used for finding static communities have highly degenerate landscapes, and the eventual partition chosen among the many partitions of similar quality is highly sensitive to small changes in the network. To reliably detect temporal communities we need not only to find a good community partition in a given snapshot but also ensure that it bears some similarity to the partition(s) found in immediately preceding snapshots. We present a new measure of partition distance called "estrangement" motivated by the inertia of inter-node relationships which, when incorporated into the measurement of partition quality, facilitates the detection of meaningful temporal communities. Specifically, we propose the estrangement confinement method, which postulates that neighboring nodes in a community prefer to continue to share community affiliation as the network evolves. Constraining estrangement enables us to find meaningful temporal communities at various degrees of temporal smoothness in diverse real-world datasets. Specifically, we study the evolution of voting behavior of senators in the United States Congress, the evolution of proximity in human mobility datasets, and the detection of evolving communities in synthetic networks that are otherwise hard to find. Estrangement confinement thus provides a principled approach to uncovering temporal communities in evolving networks.
Investigating and Fostering Metacognition in Early Math Learners

Subjects: subject: Educational Psychology
subject: Metacognition

description: While metacognition is commonly a focus of instruction within the school context and used to help improve students’ academic achievement (Larkin, 2010; Pintrich, 2002; Young, 2010), such instruction is typically limited to students in the upper grades (e.g., grades 4 and higher). This is likely due to wide-spread beliefs within the educational field that the ability to think metacognitively does not emerge until 8 to 12 years of age (Desoete, 2008). However, there is emerging evidence in support of children’s ability to be metacognitive and strategic in their learning at an earlier age (Desoete, 2008; Larkin, 2010; Shamir, Mevarech, & Gida, 2009; Whitebread et al., 2009). The present study was designed to examine whether metacognition can be developed and enhanced during the early school years through instruction, and if these developments are linked to improvements in mathematics and metacognition. The intervention was implemented through a think-aloud method that utilized Metacognitive Thinking cards as visual cues. The intervention was delivered over an eight week period by grade one classroom teachers using a combination of instructional components consisting of modelling and independent practice. The purpose of this study was: (a) to investigate the degree to which children ages 6 to 7 exhibit signs of metacognitive knowledge in their mathematical learning, (b) to determine whether metacognitive skills can be fostered and enhanced through intervention activities, and (c) to examine the relationship between metacognition and mathematical performance for this age group. Data was collected from 82 grade one students randomly assigned to one of two conditions: (a) treatment (n= 45), and (b) a comparison group (n=37). Data was collected at two time points from the four participating schools. Overall, results provide support that children aged 6-7 are capable of articulating metacognitive thoughts and these thoughts are increased with access to Metacognitive Thinking cards. However, the intervention did not demonstrate an improvement in either metacognition or mathematical abilities. Results also indicated that language abilities did not appear to be related to metacognition. Given these results, strengths and limitations of the study are considered and implications for practice and future research directions are discussed.
