description: Providing intimate partner violence (IPV)-related services to women enrolled in substance abuse treatment programs has the potential to reach a population disproportionately affected by IPV. Integrating basic IPV services into substance abuse treatment, however, poses challenges to organizations and staff. Using focus groups, the authors examined the experiences and attitudes of substance abuse treatment staff towards clients with IPV victimization experiences in order to elucidate factors that might affect the implementation of IPV services within substance abuse treatment. Seven focus groups were conducted with staff members from substance abuse treatment programs in New York City. Although participants believed that IPV is common and negatively affects client recovery, they felt competing time demands, complex confidentiality issues, insufficient training and lack of agency leadership would impede their provision of IPV-services. The study suggests that system-level assessment and change is needed to provide IPV-related services in substance abuse treatment settings.

Conventional and multi-frequency tympanometric norms for Caucasian and Chinese school-aged children
Creators: name: Bosaghzadeh, Vahideh
Publisher: name: University of British Columbia
Year: 2011

description: Objectives: The present study used tympanometric parameters to evaluate application of the current norms in Caucasian and Chinese school-aged children. The goals of this study were 1) to establish normative tympanometric data for school-aged children; 2) to determine whether the results vary significantly between Caucasian and Chinese children, male and female children, and children and adults; and 3) to compare normal paediatric tympanometric data with tympanometric data obtained from children with middle-ear pathology. Design: Tympanometry was measured in 98 subjects with normal middle-ear function with an average age of 5.8 years. There were a total of 66 participants who had abnormal middle-ear condition with a mean age of six years. Control group subjects were recruited from elementary schools in the Greater Vancouver area. Subjects with middle-ear effusion (MEE) were consisted of two groups. Those with confirmed middle-ear effusion (21 subjects) classified as “OTL confirmed” and those who recruited at elementary schools (eight subjects) were classified as “not OTL confirmed”. Statistical analysis (mixed-model ANOVA) was performed for effects of gender, ethnicity (Caucasian versus Chinese), age (child versus adult), and middle-ear condition. Conventional 226-Hz and multi-frequency tympanometry performed using GSI- Tympstar tympanometer (v. 2). . Results: Vanhuyse patterns were single peak (1B1G) at 226-Hz probe-tone frequency, but more complex patterns (e.g. 1B3G) were observed at higher probe-tone frequencies. Chinese school-aged children had lower Vea and Ytm, wider TW, and higher RF values than did Caucasian school-aged children. Diseased group tympanometric data was significantly different from normal group data. Statistical comparison of the area under receiver operating characteristic curve (AUROC) plots revealed that Ytm at 678-Hz had better test performance in distinguishing normal middle-ear status from MEE than did Ytm at other probe-tone frequencies (226-, and 1000-Hz). The results showed that Ytm from a 678-Hz probe-tone frequency, TW, and RF had the highest sensitivity, highest specificity, and statistically higher test performance in identification of MEE. Conclusions: A preliminary set of normative tympanometric data revealed significant differences between Caucasian and Chinese school-aged children and also between children and adults. Therefore, application of ethnic-specific criteria changes sensitivity or specificity of tympanometry in clinics.

Classification and clustering of sequencing data using a Poisson model

Year: 2012
Subjects: subject: Applications (stat.AP)

description: In recent years, advances in high throughput sequencing technology have led to a need for specialized methods for the analysis of digital gene expression data. While gene expression data measured on a microarray take on continuous values and can be modeled using the normal distribution, RNA sequencing data involve nonnegative counts and are more appropriately modeled using a discrete count distribution, such as the Poisson or the negative binomial. Consequently, analytic tools that assume a Gaussian distribution (such as classification methods based on linear discriminant analysis and clustering methods that use Euclidean distance) may not perform as well for sequencing data as methods that are based upon a more appropriate distribution. Here, we propose new approaches for performing classification and clustering of observations on the basis of sequencing data. Using a Poisson log linear model, we develop an analog of diagonal linear discriminant analysis that is appropriate for sequencing data. We also propose an approach for clustering sequencing data using a new dissimilarity measure that is based upon the Poisson model. We demonstrate the performances of these approaches in a simulation study, on three publicly available RNA sequencing data sets, and on a publicly available chromatin immunoprecipitation sequencing data set.

description: Bibliography: p. 155-178
description: Refugee youth resettle in Canada in search of a better future. Their adaptation process however is filled with challenges. A model of refugee adaptation and development and narrative theory were used as the guiding theoretical framework of this research. The purpose of this participatory action research study was to find out, from the youth themselves, what facilitates the successful adaptation process of refugee youth in Canada. To do so, three youth from three different continents came together to identify numerous factors that have contributed to helping them successfully adapt to the school system, learn to feel safe at school and within their community, cope with the impact of violence in their life, and adapt as a family. The findings of this study suggest that refugee youth's successful adaptation process is a shared responsibility between the youth, their family, and that of Canadian society.

description: Dielectronic recombination (DR) of singly charged ions is a reaction pathway that is commonly neglected in chemical models of molecular clouds. In this study we include state-of-the-art DR data for He+, C+, N+, O+, Na+, and Mg+ in chemical models used to simulate dense molecular clouds, protostars, and diffuse molecular clouds. We also update the radiative recombination (RR) rate coefficients for H+, He+, C+, N+, O+, Na+, and Mg+ to the current state-of-the-art values. The new RR data have little effect on the models. However, the inclusion of DR results in significant differences in gas-grain models of dense, cold molecular clouds for the evolution of a number of surface and gas-phase species. We find differences of a factor of 2 in the abundance for 74 of the 655 species at times of 104-106 yr in this model when we include DR. Of these 74 species, 16 have at least a factor of 10 difference in abundance. We find the largest differences for species formed on the surface of dust grains. These differences are due primarily to the addition of C+ DR, which increases the neutral C abundance, thereby enhancing the accretion of C onto dust. These results may be important for the warm-up phase of molecular clouds when surface species are desorbed into the gas phase. We also note that no reliable state-of-the-art RR or DR data exist for Si+, P+, S+, Cl+, and Fe+. Modern calculations for these ions are needed to better constrain molecular cloud models.
The development of salinity tolerance in juvenile pink salmon (Oncorhynchus gorbuscha)
Creators: name: Gallagher, Zoë Sydney Wilson
Publisher: name: University of British Columbia
Year: 2011

description: Following yolk-sac absorption and gravel emergence pink salmon (Oncorhynchus gorbuscha) migrate into seawater (SW) at as small as 0.2 g. This life-history strategy is in contrast with most anadromous salmonid species that generally spend 1-2 years growing in fresh water (FW) and physiologically preparing for life in SW before they migrate to SW as smolts. This study characterized for the first time the ontogeny of SW tolerance in pink salmon around the period of yolk-sac absorption. Post-hatch juvenile pink salmon were either held in FW for 26 weeks or transferred to SW every two weeks for 20 weeks to follow % survival, whole body (WB) Na+ and water content, as well as changes in wet and dry mass, gill Na+K+ATPase (NKA) activity and α1a and α1b mRNA isoform expression. An increase in gill NKA activity and the ratio of the α1b/α1a isoform expression, a plateau in WB water and Na+ levels, and the switch from catabolic to anabolic growth were all observed at the time of yolk-sac absorption in fish retained in freshwater. At this time, morbidity following subsequent SW transfer fell to 0% from a high of 100% for newly hatched alevins, but then rose to 25% in older fry, suggesting that a window of increased salinity tolerance exists for pink salmon at the time of yolk-sac absorption. This proposed window of SW tolerance is similar to the smolt window that has been identified for other salmonids; but in pink salmon appears to be endogenously mediated, as fish were reared under constant (12L:12D) photoperiod and at 5˚C throughout the study. Moreover, smoltification is incomplete since transfer to SW further elevated gill NKA activity and increased gill NKA α1b/α1α isoform expression ratio 8-fold at yolk-sac absorption. Thus, even the most SW-tolerant fish were not fully prepared for SW before entry, but responded directly to SW by further increasing hypo-osmoregulatory ability. This study filled the previously existing void of knowledge regarding the acquisition of salinity tolerance in juvenile pink salmon.

description: Osteoarthritis is a degenerative joint disease involving the breakdown of articular cartilage, which is common after injury or with aging. Cartilage lubrication is a vital mechanism for the protection and maintenance of joints. Proteoglycan 4 (PRG4), a glycoprotein present in synovial fluid (SF), contributes to the boundary lubrication of cartilage and maintenance of the joint. PRG4 also acts synergistically with hyaluronan (HA), another molecule present in SF, as cartilage boundary lubricants. The objective of this thesis was to determine 1) PRG4 and HA concentration, 2) HA molecular weight (MW) distribution, 3) cartilage lubricating ability, and 4) the isoelectric point (pl) of PRG4 in SF from surgical sham (SHAM), anterior cruciate ligament (ACL)/medial collateral ligament (MCL) transection, and lateral meniscectomy (MEN) in a post-knee injury ovine model at 20 weeks. SHAM (n=S), ACL/MCL transection (n=6), and MEN (n=S) ovine SF ( oSF) was collected at euthanization 20 weeks after surgery, with the left joint serving as the non-operative control (CTRL). PRG4 and HA concentration in oSF was measured by a sandwich enzyme-linked immunosorbent assay (ELISA) and HA MW distribution by agarose gel electrophoresis. A cartilage-cartilage friction test under boundary lubrication conditions was used to assess the cartilage lubricating ability of oSF. The pl of PRG4 was determined by two­dimensional (2D) gel electrophoresis. PRG4 and HA concentration in SHAM, ACL/MCL, and MEN oSF was similar in comparison to the contralateral CTRL oSF. The HA MW distribution in the SHAM, ACL/MCL, and MEN oSF for all ranges were similar with respect to the contralateral CTRL oSF. The kinetic coefficient of friction in phosphate buffered saline was si nificantly higher than all groups, both operated, CTRL oSF, and bovine SF in all cases, which was lower and similar. The pl of PRG4 is ~4.0-4.4 and the pl of PRG4 may have shifted to a higher pl in MEN oSF, in compared to contralateral CTRL oSF. These results suggest that lubricant composition and function was normal 20 weeks post-knee surgery in this model and 2D electrophoresis may provide insight into the structure of PRG4 glycosylations.

description: I Zw 18 is a prototype Blue Compact Dwarf (BCD), characterized by a strong starburst and extremely low metallicity (Z ~ 0.02 Zsun). It has long been considered a candidate young galaxy in the Local Universe, but recent studies indicate the presence of old stars. We analysed archival VLA observations of the 21 cm line and found that the HI associated to the starburst region forms a compact fast-rotating disk. The HI column densities are very high, up to ~50-100 Msun/pc^2 (~0.6-1.2 x 10^22 atoms/cm^2). The rotation curve is flat with a steep rise in the inner parts, indicating the presence of a strong central concentration of mass. Mass models with a dark matter halo show that baryons may dominate the gravitational potential in the inner regions. A radial inflow/outflow motion of ~15 km/s is also present. I Zw 18 appears structurally different from typical dwarf irregulars in terms of gas distribution, stellar distribution and dynamics. It may be considered as a "miniature" high-surface-brightness disk galaxy. These dynamical properties must be tightly related to the starburst. They also shed new light on the question of the descendants of BCDs. There is also extended HI emission towards the outlying stellar complex I Zw 18 C and a ~13.5 kpc HI tail. An interaction/merger between gas-rich dwarfs is the most likely explanation for the starburst.

Geomechanical upscaling and modeling of interbedded shales within reservoirs

description: Some pages are in colour.
description: The concept of compaction of reservoirs, mainly sandstone layers, has often been studied and the methods for assessments of its impact on the subsidence have been developed in the oil and gas industry. However, the effect of the interbedded shales compaction on the subsidence has been rarely discussed in reservoir and geomechanical simulation studies for surface subsidence and reservoir compaction prediction. This study attempts to assess the effect of interbedded shales layers ( which are on a sub-grid scale) on the compaction behaviour of the reservoirs. The results can be considered as a "geomechanical upscaling" technique which can be used to make more accurate prediction of reservoir compaction and surface subsidence. The specific parameters considered are the geometry and permeability of the shale laminations, reservoir permeability, Young's modulus, Poisson ratio, reservoir average pressure, shale's pressure lag during reservoir depletion and desired flow rate. Parametric and numerical calculations, based on a semi-analytical solution and finite-difference solutions of a single element for uniaxial displacement conditions have been used to develop an upscaling formula which was implemented in the geomechanical simulator based on the Net-to-Gross (NTG) concept. The NTG is the ratio that represents the total thickness of the productive layers divided by the total (gross) thickness of the reservoir. In reservoir characterization and simulation, the NTG concept is applied to each computational cell. The results of the field application show that the inclusion of the NTG effect contributes a significant subsidence reduction for Neptune field due to the pressure lag of the shale layers.

description: The volume of data from telescopes stored in archives has increased rapidly over time. The ALMA archive, for instance, holds such an immense amount of information that astronomers cannot effectively access it without search tools specifically designed for this archive. These tools function by assigning each observation with keywords, allowing users to search based on these keywords. However, this system has its shortcomings. Firstly, the astronomer assigning an observation might not recognize or include all relevant keywords. Secondly, given the vast and varied phenomena in our universe, creating a comprehensive keyword list becomes a near-impossible task.
Machine learning offers enormous potential for both finding objects of interest and then interpret their morphology in terms of physically meaningful properties. In this project, we trained a convolutional  neural network to detect gaussian disks with extensions in the ALMA-archive. Extensions in the dust emission perpendicular to disks could be a sign of dust leaving the disk via winds, but to date only a handful of such observations have been acquired. We want to know whether this is a common feature for young disks or not. Our data set originates from five unique observations and are used to train a neural network.
By using linear and non-linear augmentation techniques (artificially creating data), we expanded the data set and trained a neural network. Preliminary results show that this methodology can be used to find observations in the archive, that resembles the input training data. In other words, Gaussian disks with extensions can be identified. A future, and long-term, goal is to refine the approach in such a way that the code can handle data and perform morphological classification for various archives.

description: We remark on the existence of non-linearly realized conformal symmetries for scalar adiabatic perturbations in cosmology. These conformal symmetries are present for any cosmological background, beyond any slow-roll or quasi-de Sitter approximation. The dilatation transformation shifts the curvature perturbation by a constant, and corresponds to the well-known symmetry under spatial rescaling. We argue that the scalar sector is also invariant under special conformal transformations, which shift the curvature perturbation by a term linear in the spatial coordinates. We discuss whether these conformal symmetries can be extended to include tensor perturbations. Tensor modes introduce their own set of non-linearly realized symmetries. We identify an infinite set of large gauge transformations which maintain the transverse, traceless gauge condition, while shifting the tensor mode non-trivially.

Two-dimensional physical model study on mechanisms of enhanced heavy oil recovery by chemical flooding

Year: 2012

description: Bibliography: p. 83-90
description: Some pages are in colour.
description: The dominant mechanism of enhanced heavy oil recovery by chemical flooding is studied by conducting various chemical slug injections into a two-dimensional physical model. A total of sixteen tests including seven single-slug tests, seven two-slug tests and two tests with chemical slug alternated with air slugs were conducted to test the contribution of alkaline, surfactant, polymer and their combinations to enhanced heavy oil recovery. The relationship between the tertiary oil recovery and the pressure drop of the seven single-slug floods was analyzed, and it was discovered that the two have a good correlation. Comparison of the tertiary oil recoveries of different chemical slug tests shows that the improved recovery for the heavy oil used in this study is mainly due to the plugging of water channels, or the reduction of water mobility. The results of two-slug tests show that after regular alkaline/surfactant/polymer flooding, the second polymer slug injection can recover more oil, if a water slug injection is applied between the two chemical slugs. Experimental results and conclusions were further studied in the field application of polymer flooding, based on simulation results using actual geological and reservoir data and the production history data from Pelican Lake reservoir.

description: Silicene is a monolayer of silicon atoms forming a honeycomb lattice. The lattice is actually made of two sublattices with a tiny separation. Silicene is a topological insulator, which is characterized by a full insulating gap in the bulk and helical gapless edges. It undergoes a phase transition from a topological insulator to a band insulator by applying external electric field. Analyzing the spin Chern number based on the effective Dirac theory, we find their origin to be a pseudospin meron in the momentum space. The peudospin degree of freedom arises from the two-sublattice structure. Our analysis makes clear the mechanism how a phase transition occurs from a topological insulator to a band insulator under increasing electric field. We propose a method to determine the critical electric field with the aid of diamagnetism of silicene. Diamagnetism is tunable by the external electric field, and exhibits a singular behaviour at the critical electric field. Our result is important also from the viewpoint of cross correlation between electric field and magnetism. Our finding will be important for future electro-magnetic correlated devices.

description: Formation of Long-Term Agro-ecosystem Research (LTAR) networks in 2012 and the USDA Regional Climate Hubs in 2014 provide networks to address climate change and agriculture. Eighteen sites in the LTAR network address, through replicated experimental designs, common problems of how to "Sustain or Enhance Productivity, Profitability, and Ecosystem Services in Agro-ecosystems and Agricultural Landscapes" for "business as usual" and "aspirational agriculture" management strategies. Common core measurements will be taken (e.g., productivity; carbon, water and energy fluxes; greenhouse gas measurements; wind and water erosion) and used for cross-site comparisons, meta-analyses with other network data (e.g., National Ecological Observatory Network, NEON; Long-Term Ecological Research, LTER), and in model simulations/projections for predicted climate scenarios. Data will feed into 7 USDA Regional Climate Hubs, tasked with enhancing decisions by agricultural producers on the ground to reduce enterprise risk, increase resilience of lands, improve soil health, and increase efficiency of production (e.g., more crop per drop) in a changing climate, including more frequent extreme events. Climate-smart decisions, such as matching stocking/grazing decisions to improved predictions of seasonal weather (precipitation and temperature) or matching appropriate crops to predicted growing seasons (including earlier onset of growing season and increased frost free days), are reliant on development and transfer of science-based, region-specific information and technologies through coordinated efforts with local and regional partners in Federal and state agencies, NGOs, private companies, and Tribes. Information transfer can include: trusted sources of Extension, state climatologists; modification of existing conservation programs through NRCS or others; and peer-to-peer communications through social media.

description: We study the linear and nonlinear structure formation in the dilaton and symmetron models of modified gravity using a generic parameterisation which describes a large class of scenarios using only a few parameters, such as the coupling between the scalar field and the matter, and the range of the scalar force on very large scales. For this we have modified the N-body simulation code ECOSMOG, which is a variant of RAMSES working in modified gravity scenarios, to perform a set of 110 simulations for different models and parameter values, including the default LCDM. These simulations enable us to explore a large portion of the parameter space. We have studied the effects of modified gravity on the matter power spectrum and mass function, and found a rich and interesting phenomenology where the difference with the LCDM template cannot be reproduced by a linear analysis even on scales as large as k~0.05 h/Mpc. Our results show the full effect of screening on nonlinear structure formation and the associated deviation from LCDM. We also investigate how differences in the force mediated by the scalar field in modified gravity models lead to qualitatively different features for the nonlinear power spectrum and the halo mass function, and how varying the individual model parameters changes these observables. The differences are particularly large in the nonlinear power spectra whose shapes for f(R), dilaton and symmetron models vary greatly, and where the characteristic bump around 1 h/Mpc of f(R) models is preserved for symmetrons, whereas an increase on much smaller scales is particular to symmetrons. No bump is present for dilatons where a flattening of the power spectrum takes place on small scales. These deviations from LCDM and the differences between modified gravity models, such as dilatons and symmetrons, could be tested with future surveys.

description: Sulphur (S) is a non-refractory alpha-element that is not locked into dust grains in the interstellar medium. Thus no correction to the measured, interstellar sulphur abundance is needed and it can be readily compared to the S content in stellar photospheres. Here we present the first measurement of sulphur in the metal poor globular cluster (GC) NGC 6397, as detected in a MIKE/Magellan high signal-to-noise, high-resolution spectrum of one red giant star. While abundance ratios of sulphur are available for a larger number of Galactic stars down to an [Fe/H] of ~ -3.5 dex, no measurements in globular clusters more metal poor than -1.5 dex have been reported so far. We find a NLTE, 3-D abundance ratio of [S/Fe] = +0.52 +/- 0.20 (stat.) +/- 0.08 (sys.), based on the S I, Multiplet 1 line at 9212.8A. This value is consistent with a Galactic halo plateau as typical of other alpha-elements in GCs and field stars, but we cannot rule out its membership with a second branch of increasing [S/Fe] with decreasing [Fe/H], claimed in the literature, which leads to a large scatter at metallicities around -2 dex. The [S/Mg] and [S/Ca] ratios in this star are compatible with a Solar value to within the (large) uncertainties. Despite the very large scatter in these ratios across Galactic stars between literature samples, this indicates that sulphur traces the chemical imprints of the other alpha-elements in metal poor GCs. Combined with its moderate sodium abundance ([S/Na]_NLTE=0.48), the [S/Fe] ratio in this GC extends a global, positive S-Na correlation that is not seen in field stars and might indicate that proton-capture reactions contributed to the production of sulphur in the (metal poor) early GC environments.

description: In Canada, many heavy oil fields are nearing the end of the primary production. These reservoirs have been depleted of their natural energy, and have been disturbed to an unknown extent through the formation of wormholes. There is a large amount of heavy oil resources and only about 8-10% of its original oil in place (OOIP) can be recovered with the primary production. In small or thin reservoirs, the thermal recovery methods do not work and so non thermal recovery methods such as alkali surfactant flooding seem as suitable alternatives in improving the oil recoveries. This research is a laboratory study that investigates the mechanisms of the pore level displacement in chemical floods for heavy oil. The Alkali-Surfactant is used as the chemical to generate oil and water emulsions which can in turn improve the oil recoveries. A bulk liquid study is performed in order to choose the optimal concentrations for both the alkali and the surfactant. Furthermore, data is obtained from three core flood runs with unconsolidated sand packs containing heavy oil of viscosity 15,800 cp at 23 C. A series of high injection rate and low injection rate core floods are performed and finally, there is another set of core floods performed on two cores in parallel having a large permeability difference between them in order to get a more detailed insight on reservoirs containing channels and wormholes. The data collected from all these experiments alongside the analysis of the results are discussed in detail which provides a further step forward in discovering the mechanisms and the potential implications for improved recovery processes for these systems.
TFH Mixing Patterns, Large $θ_{13}$ and $Δ(96)$ Flavor Symmetry

description: We perform a comprehensive analysis of the Toorop-Feruglio-Hagedorn (TFH) mixing patterns within the family symmetry $Δ(96)$. The general neutrino mass matrix for the TFH mixing and its symmetry properties are investigated. The possible realizations of the TFH mixing in $Δ(96)$ are analyzed in the minimalist approach. We propose two dynamical models which produce the TFH mixing patterns at leading order. The full flavor symmetries are $Δ(96)\times Z_3\times Z_3$ and $Δ(96)\times Z_5 \times Z_2$ respectively. The next to leading order terms introduce corrections of order $λ^2_c$ to the three mixing angles in both models. The allowed mixing patterns are studied under the condition that the Klein four subgroups and the cyclic $Z_N$ subgroups with $N\geq3$ are preserved in the neutrino and the charged lepton sector respectively. We suggest that the deformed tri-bimaximal mixing is a good leading order approximation to understanding a largish reactor angle.

Dreaming a way out : social planning responses to the agency of lone mothers experiencing neo-liberal welfare reform in western Canada
Creators: name: Vilches, Silvia Leonor

description: Neo-liberal welfare reform, which was implemented in 2002 in BC, Canada, contests the agency of welfare recipients by claiming the right to legitimize motivation. The impact of this on a diverse group of impoverished lone mothers (n = 17) with young children in the city of Vancouver was explored using a critical feminist lens. Grounded theory and narrative analysis were used in a qualitative mixed method study to investigate how women are creating a future for themselves and their children, how they resist and interrogate the imposition of policy directives, and the implications for social planning. The results of in-depth interviews from a three year qualitative longitudinal study show how women mediate between public expectations and private needs by deploying identity to survive. Their actions resist individualizing policy discourses that frame them as people in need. Meanwhile, because of insufficient benefits, they engage in the informal economy to survive, transforming private goods, including sometimes, their bodies, into benefits through barter, sale, and assuming debt. As they scrabble for resources, they create and care for community as a means of surviving, ensuring the future well-being of their children and affirming their identity as valuable members of society. These women manage the risk of failing to support themselves, their children and others, by constituting themselves through dreaming a way out. When their dreaming is at risk of failing, the women risk losing their families. If a key normative goal of social planning is to create an equitable and inclusive society, then these findings challenge the often racialized discourses around poverty and affirm the contribution of impoverished lone parent families, including Aboriginal families, to urban life. A conceptual shift away from the polarized debate created by identifying poverty with a lack of finances and toward the capabilities model used at the international level would enable local planners. Spatial planning tools could help meet the dilemmas impoverished lone parent women face as they use place-based resourcing activities to survive. I argue that without recognizing women’s agency, impoverished lone parent families remain invisible and underserved by existing planning practices.

description: In this paper we analyze a suite of cosmological simulations of modified gravitational action f(R) models, where cosmic acceleration is induced by a scalar field that acts as a fifth force on all forms of matter. In particular, we focus on the bispectrum of the dark matter density field on mildly non-linear scales. For models with the same initial power spectrum, the dark matter bispectrum shows significant differences for cases where the final dark matter power spectrum also differs. Given the different dependence on bias of the galaxy power spectrum and bispectrum, bispectrum measurements can close the loophole of galaxy bias hiding differences in the power spectrum. Alternatively, changes in the initial power spectrum can also hide differences. By constructing LCDM models with very similar final non-linear power spectra, we show that the differences in the bispectrum are reduced (<4%) and are comparable with differences in the imperfectly matched power spectra. These results indicate that the bispectrum depends mainly on the power spectrum and less sensitively on the gravitational signatures of the f(R) model. This weak dependence of the matter bispectrum on gravity makes it useful for breaking degeneracies associated with galaxy bias, even for models beyond general relativity.

description: A new vision of structural health monitoring (SHM) is presented, in which the ultimate goal of SHM is not limited to damage identification, but to describe the structure by a probabilistic model, whose parameters and uncertainty are periodically updated using measured data in a recursive Bayesian filtering (RBF) approach. Such a model of a structure is essential in evaluating its current condition and predicting its future performance in a probabilistic context. RBF is conventionally implemented by the extended Kalman filter, which suffers from its intrinsic drawbacks. Recent progress on high-fidelity propagation of a probability distribution through nonlinear functions has revived RBF as a promising tool for SHM. The central difference filter, as an example of the new versions of RBF, is implemented in this study, with the adaptation of a convergence and consistency improvement technique. Two numerical examples are presented to demonstrate the superior capacity of RBF for a SHM purpose. The proposed method is also validated by large-scale shake table tests on a reinforced concrete two-span three-bent bridge specimen.

description: Bibliography: p. 142-158
description: Are the US and Pakistan friends or foes? A methodological framework of constructivism will be employed to answer this question. First, constructivism will be outlined, and its applicability to the case of the US-Pakistan alliance will be demonstrated. The specific constructivist tools to be used - narrativity and role identity formation - and their applicability to the relationship between Pakistan and the US will be described. The national narrative formation process of both states will then be addressed, and will include such elements as religion, domestic politics, and foreign policy. Interactions between the two states and the process by which role identities are formed will then be described. This will include themes such as victirnhood and exceptionalism. Finally, this paper will address the thesis question and conclude that the US and Pakistan are fundamentally foes, not friends.
