description: A recent study of younger adults suggests that, compared to repeated individual recall trials, repeated collaborative recall trials produce better individual recall after a short delay (Blumen & Rajaram, 2008). Our study was designed to determine if such collaboration benefits would remain after a one-week delay, in both younger and older adults. Sixty younger (M age = 24.60) and 60 older (M age = 67.35) adults studied a list of words and then completed either two collaborative recall trials followed by two individual recall trials, or four individual recall trials. A five-min delay was inserted between the first three recall trials. The fourth recall trial was administered 1 week later. Collaborative recall was completed in groups of three individuals working together. Both younger and older adults benefitted from repeated collaborative recall trials to a greater extent than repeated individual recall trials, and such collaboration benefits remained after a one-week delay. This is the first demonstration of collaboration benefits on later individual recall at delays as long as 1 week, in both younger and older adults. Findings are discussed within the context of the negative effects of collaboration associated with group memory (collaborative inhibition) and the positive effects of collaboration associated with later individual memory (collaboration benefits).

description: Understanding the magnetic configuration of the source regions of coronal mass ejections (CMEs) is vital in order to determine the trigger and driver of these events. Observations of four CME productive active regions are presented here, which indicate that the pre-eruption magnetic configuration is that of a magnetic flux rope. The flux ropes are formed in the solar atmosphere by the process known as flux cancellation and are stable for several hours before the eruption. The observations also indicate that the magnetic structure that erupts is not the entire flux rope as initially formed, raising the question of whether the flux rope is able to undergo a partial eruption or whether it undergoes a transition in specific flux rope configuration shortly
before the CME.

description: Bilayer membranes self-assembled from simple amphiphiles in solution always have a planar ground-state shape. This is a consequence of several internal relaxation mechanisms of the membrane and prevents the straightforward control of vesicle size. Here, we show that this principle can be circumvented and that direct size control by molecular design is a realistic possibility. Using coarse-grained calculations, we design tetrablock copolymers that form membranes with a preferred curvature, and demonstrate how to form low-polydispersity vesicles while suppressing micellization.

description: We describe the temperature-chemical potential phase diagrams of holographic models of a range of strongly coupled gauge theories that display chiral symmetry breaking/restoration transitions. The models are based on the D3/probe-D7 system but with a phenomenologically chosen running coupling/dilaton profile. We realize chiral phase transitions with either temperature or density that are first or second order by changing the dilaton profile. Although the models are only caricatures of QCD they show that holographic models can capture many aspects of the QCD phase diagram and hint at the dependence on the running coupling.

description: Little information exists on the performance of black versus white patients with Alzheimer's disease on neuropsychological tests for dementia.In this study, we compared performance on the CERAD (Consortium to Establish a Registry for Alzheimer's Disease) neuropsychological battery between white (n equals 830) and black (n equals 158) patients with Alzheimer's disease enrolled in the CERAD study at 23 university medical centers in the United States. The black patients were older, had fewer years of formal education, and were more impaired in their activities of daily living than were the white patients. After controlling for these characteristics and for duration of the disease and severity of dementia, there were differences in the performance of black and white patients on several of the cognitive measures. Black patients scored lower than whites on tests of visual naming and constructional praxis and on the Mini-Mental State Examination. There were no statistical differences in performance on tests of fluency and word list memory. These findings suggest that cultural or experiential differences may modify performance on specific neuropsychological tests. These factors, in addition to age and educational background, should be considered when interpreting performance on neuropsychological tests in elderly black patients with dementia.

description: A universal dimer is subject to secondary collisions with atoms when formed in a cloud of ultracold atoms via three-body recombination. We show that in a collisionally opaque medium, the value of the scattering length that results in the maximum number of secondary collisions may not correspond to the Efimov resonance at the atom-dimer threshold and thus can not be automatically associated with it. This result explains a number of controversies in recent experimental results on universal three-body states and supports the emerging evidence for the significant finite range corrections to the first excited Efimov energy level.

Multi-criteria decision based evaluation of municipal infrastructure projects

Publisher: name: University of British Columbia
Year: 2012

description: Public and private agencies that are in charge of planning, evaluating, and executing the operation, maintenance, and renewal of assets are always faced with difficulties, such as aging assets and funding limitations. In addition, the growth of population and increasing environmental protection and preservation concerns and regulations have already put more pressure on involved agencies and organizations to establish more efficient, effective and even more sustainable investment plans. The motivation of the thesis is to assist the agencies involved in asset management to allocate their funds and resources more efficiently and cost effectively in order to provide a basis for reducing the amount of future budget requirement and keeping the assets at the same or even better condition. This research reviews the strategic goals and objectives of typical municipalities in order to identify the strengths and weaknesses of ongoing municipal asset management; an efficient and more practical decision making process at the strategic level of municipal asset management has been developed. Infrastructure asset management entails multiple steps, processes, and management levels. A formal and typical structure management of infrastructure systems can be divided to three main levels: project level, network level (or tactical level), and strategic level. This thesis concentrates on the strategic planning that is done by senior managers in municipal governments. Furthermore, municipal infrastructure in this research is limited to pavements, bridges, water and sewer networks; however, all findings are applicable to similar type infrastructure assets. The methodology of this research entails four main parts: preparing a comprehensive literature review of the domain, developing the decision making process, designing and conducting a survey regarding municipal priorities, analyzing the responses, and proposing and testing a suitable and practical solution for decision making for municipalities.

description: Conditional evolution is crucial for generating non-Gaussian resources for quantum information tasks in the continuous variable scenario. However, tools are lacking for a convenient representation of heralded process in terms of quantum maps for continuous variable states, in the same way as Wigner functions are able to give a compact description of the quantum state. Here we propose and study such a representation, based on the introduction of a suitable transfer function to describe the action of a quantum operation on the Wigner function. We also reconstruct the maps of two relevant examples of conditional process, that is, noiseless amplification and photon addition, by combining experimental data and a detailed physical model. This analysis allows to fully characterize the effect of experimental imperfections in their implementations.

description: Extrapyramidal signs frequently accompany Alzheimer's disease (AD), but the pathological substrate remains unknown. Clinical and postmortem information from patients with AD, Parkinson's disease, or progressive supranuclear palsy and control subjects seen at a large tertiary medical center between 1989 and 1994 was examined. AD patients who had taken neuroleptics and AD brains that also contained Lewy bodies were excluded. Sections of basal ganglia, subthalamic nucleus, and substantia nigra were examined for neurofibrillary tangles and neuropil threads and the nigra for neuronal numbers. The presence of extrapyramidal signs was determined using the Unified Parkinson's Disease Rating Scale. Patients with AD (with or without extrapyramidal signs) did not show neuronal loss in the nigra compared to control subjects, while both Parkinson's disease and progressive supranuclear palsy brains showed marked depletion. The number of neurofibrillary tangles and neuropil threads was increased in AD (with or without extrapyramidal signs) nigra compared to control tissue, and also in progressive supranuclear palsy nigra, but not Parkinson's disease nigra. The numbers of nigral neurofibrillary tangles and neuropil threads were positively related to extrapyramidal signs in AD. There were no correlations between tangles and threads in the basal ganglia or subthalamic nucleus and extrapyramidal signs in AD. Thus, extrapyramidal signs in AD correlate best with tangle pathology in the nigra and do not require the concomitant presence of Lewy bodies.

description: We analyze the properties of a Luttinger liquid under the influence of a periodic driving of the interaction strength. Irrespective of the details the driven system develops an instability due to a parametric resonance. For slow and fast driving, however, we identify intermediate long-lived meta-stable states at constant time-averaged internal energies. Due to the instability perturbations in the fermionic density are amplified exponentially leading to the buildup of a superlattice. The momentum distribution develops a terrace structure due to scattering processes that can be associated with the absorption of quanta of the driving frequency.

description: We attempted to characterize the changes in cognition associated with the earliest, or preclinical, stages of Alzheimer's disease (AD) by administering a comprehensive neuropsychological test battery to a group of initially nondemented older adults participating in a prospective epidemiologic study of dementia. Using Cox regression analyses, we examined the associations between baseline neuropsychological test scores and subsequent development of AD. Results confirmed preliminary findings that baseline scores on the Boston Naming Test, Immediate Recall on the Selective Reminding Test, and the Similarities subtest of the Wechsler Adult Intelligence Scale-Revised were significantly and independently associated with later diagnosis of AD. Analyses controlled for the effects of age, education, sex, and language of test administration. These results lend support to the notion of a preclinical phase of AD and indicate that this very early stage of AD is characterized by poor word-finding ability, abstract reasoning, and memory.

Maximizing climate and health benefits in household energy carbon credit projects
Creators: name: Freeman, Olivia Esther
Publisher: name: University of British Columbia
Year: 2012

description: ‘Improved’ cooking technologies, which in general are cleaner burning with higher levels of complete combustion, greater efficiency and better heat transfer then less-efficient cooking technologies, have been generally understood in the global community to be a ‘win-win’ development intervention creating a multitude of benefits. Yet as in most environment-development efforts there are many unacknowledged tradeoffs that exist under the all-encompassing ‘win-win’ claims. In this study tradeoffs made between two co-benefits of cookstove projects, climate and health, are examined under the framework of carbon financing mechanisms. Two methodologies used to calculate carbon credits for cookstove projects are compared, the Gold Standard method and the Clean Development Mechanism method. Different carbon credit scenarios are evaluated for how they compare to estimated health impacts when switching from a traditional biomass stove to each of the other ten alternative stove-fuel combinations including three basic improved biomass stoves, two gasifying biomass stoves, two coal stoves, one charcoal stove and two liquid fossil fuel stoves. Tradeoffs between the maximization of co-benefits were found to exist, with carbon credits inherently accounting for climate benefits, but not health. The three stove types achieving the highest levels of co-benefits were the two liquid fossil fuel fueled stoves included in the analyses, kerosene and liquid petroleum gas, and a more technologically advanced gasifying biomass stove with a battery powered fan. Yet they were also the most expensive and the fossil fuel stoves were treated very differently in the two methodologies, creating a diffusion barrier to achieve the highest maximization of co-benefits. The Gold Standard methodology consistently calculated more carbon credits than the Clean Development Mechanism, largely due to its inclusion of methane emissions in its calculations. Including black carbon emissions in theoretical carbon credit calculations also significantly increased the number of credits calculated. If accounted for in such equations this could greatly increase the amount of income earned per project as well as change how such projects are designed and approached due to the large increase in potential credits calculated. As health and other development benefits are not inherently included in carbon credit calculations, in order to achieve ‘win-win’ outcomes, deliberate decisions about project design need to be made to ensure such objectives are actually met and not simply assumed.

description: 2-joins are edge cutsets that naturally appear in the decomposition of several classes of graphs closed under taking induced subgraphs, such as balanced bipartite graphs, even-hole-free graphs, perfect graphs and claw-free graphs. Their detection is needed in several algorithms, and is the slowest step for some of them. The classical method to detect a 2-join takes $O(n^3m)$ time where $n$ is the number of vertices of the input graph and $m$ the number of its edges. To detect \emph{non-path} 2-joins (special kinds of 2-joins that are needed in all of the known algorithms that use 2-joins), the fastest known method takes time $O(n^4m)$. Here, we give an $O(n^2m)$-time algorithm for both of these problems. A consequence is a speed up of several known algorithms.

description: Background: Although the proportion of cases of acquired immunodeficiency syndrome related to intravenous drug use has increased dramatically over the past decade, there has been no longitudinal examination of primary neurologic disease in this group. Objective: To study the development of neurologic disease in human immunodeficiency virus (HIV)—negative and HIV-positive men and women who were intravenous drug users over a 3.5-year period. Design: Prospective observational cohort study. Setting: Subjects were recruited from an infectious disease clinic at a New York City Hospital or from a methadone maintenance program. Participants: Ninety-nine HIV-negative (62 men and 37 women) and 124 HIV-positive (85 men and 39 women) intravenous drug users volunteered. Main Outcome Measure: The development of clinically significant manifestations in six neurologic domains. Results: With multivariate adjustment for current and past substance abuse, age, education, and head injury, we examined the odds of developing HIV-related neurologic disease. Extrapyramidal signs and reduced motor ability became increasingly apparent over time in HIV-infected men as their CD4 cell count declined and as the subjects developed the acquired immunodeficiency syndrome. Fewer neurologic signs were seen in the women. Conclusions: The impact of HIV infection among intravenous drug users parallels that in homosexual men and is independent of alcohol and other drug use.

description: Pattern formation in microbial colonies of competing strains under purely space-limited population growth has recently attracted considerable research interest. We show that the reproduction time statistics of individuals has a significant impact on the sectoring patterns. Generalizing the standard Eden growth model, we introduce a simple one-parameter family of reproduction time distributions indexed by the variation coefficient δ \in [0, 1], which includes deterministic (δ = 0) and memoryless exponential distribution (δ = 1) as extreme cases. We present convincing numerical evidence and heuristic arguments that the generalized model is still in the KPZ universality class, and the changes in patterns are due to changing prefactors in the scaling relations, which we are able to predict quantitatively. At the example of Saccharomyces cerevisiae, we show that our approach using the variation coefficient also works for more realistic reproduction time distributions.

description: Results of therapeutic trials with physostigmine in the treatment of Alzheimer disease (AD) have been inconsistent and controversy persists concerning safety and efficacy. In a double-blind, placebo-controlled, crossover study, patients received 6 weeks of oral physostigmine (OP) and placebo in random order. Twenty-nine patients with AD received as much as 16 mg/day of OP and were assessed with neuropsychological and functional measures. No significant cardiac side effects were noted, though other systemic adverse effects were noted, requiring dose reduction in four patients. There was a slight but significant improvement (12%) in performance on the selective reminding test with physostigmine and the memory performance was correlated with dosage. This improvement compares favorably with the 15% decrease in scores seen in an untreated comparison cohort followed for an equivalent time period. There was a trend toward an improvement in communication and a reduction in memory complaint. These results suggest that oral physostigmine is safe and may improve memory in AD.

Experimental bounds on the collapse time are reported (of order 0.1 ms to 0.1 ps) and its convenient dimensionless measure is introduced. This parameter helps to identify the areas where sensitive probes of the possible collapse dynamics can be done. Examples are experiments with Bose-Einstein condensates, ultracold neutrons or ultrafast optics.

description: Adhesion bonds between membranes and surfaces are attracted to each other via effective interactions whose origin the entropy loss due to the reduction in the amplitude of the membrane thermal fluctuations in the vicinity of the adhesion bonds. These fluctuation-induced interactions are also expected to drive the adhesion bonds toward the rim of the cell, as well as toward the surfaces of membrane inclusions. In this paper, we analyze the attraction of adhesion bonds to the cell inner and outer boundaries. Our analysis shows that the probability distribution function of a single (diffusing) adhesion bond decay algebraically with the distance from the boundaries. Upon increasing the concentration of the adhesion bonds, the attraction to the boundaries becomes strongly self-screened.

Inclusive production of a pair of hadrons separated by a large interval of rapidity in proton collisions

description: We consider within QCD collinear factorization the inclusive process $p+p\to h_1+h_2+X$, where the pair of identified hadrons, $h_1,h_2$, having large transverse momenta is produced in high-energy proton-proton collisions. In particular, we concentrate on the kinematics where the two identified hadrons in the final state are separated by a large interval of rapidity $Δy$. In this case the (calculable) hard part of the reaction receives large higher order corrections $\sim α^n_s Δy^n$. We provide a theoretical input for the resummation of such contributions with next-to-leading logarithmic accuracy (NLA) in the BFKL approach. Specifically, we calculate in NLA the vertex (impact-factor) for the inclusive production of the identified hadron. This process has much in common with the widely discussed Mueller-Navelet jets production and can be also used to access the BFKL dynamics at proton colliders. Another application of the obtained identified-hadron vertex could be the NLA BFKL description of inclusive forward hadron production in DIS.

description: We evaluated neuropsychological test performance of 168 homosexual and bisexual men with and without human immunodeficiency virus (HIV) infection (113 HIV+ subjects and 55 HIV- controls) over 4.5 years of semiannual follow-up. Analyses of the longitudinal data were performed by applying generalized estimating equations (GEEs) to regression analyses with repeated measures. Compared with the HIV- men, the HIV+ subjects performed more poorly on memory testing. Performance on all tests tended to improve over time, but this improvement was attenuated or eliminated in the HIV+ group for tests of language and attention. Within the HIV+ subjects, improvement over time in tests of memory, executive function, language, and attention was attenuated or eliminated in patients with lower CD4 levels; more advanced HIV disease was associated with poorer memory and executive function and with attenuated or reduced learning effects for memory, motor speed, and language tests. Clinically significant neurologic findings were associated with worse memory and orientation and with attenuated or reversed learning effects for memory, language, and attention tests. There were 33 deaths in the HIV+ group. In the men who died, there was more rapid decline in executive, language, and attentional test performance. These observations remained significant after controlling for HIV disease severity. We conclude that HIV infecting the CNS results in progressive cognitive change that is closely associated with neurologic findings. In addition, our findings suggest a relation between more rapid cognitive progression and death.

description: Background There is little information on the efficacy and side effects of antidepressant treatment in elderly patients with combined depression and cognitive impairment without dementia (DEP-MCI), and it is unclear if cognitive performance improves with antidepressant response in these patients. Methods In 39 elderly DEP-MCI patients, changes in depression and cognitive impairment were evaluated with open sertraline treatment up to 200 mg/day for 12 weeks. Results Of the 26 completers, 17 were responders and nine were non-responders. Diagnostic subtype of depression was unrelated to response. ANCOVA on WAIS-R digit symbol percent change scores revealed a significant effect for responder status (F = 5.59, p < 0.03), and age (F = 0.24, p < 0.64) and education (F = 1.64, p < 0.22) were not significant covariates. From pre-trial to post-trial, responders improved in WAIS-R digit symbol percent change scores (Mean −10% SD 24) while non-responders declined (Mean 14% SD 18; t = 2.60, p < 0.02). Other neuropsychological measures were unrelated to response. Percent change in HRSD scores showed significant inverse correlations with percent change in several cognitive measures. Conclusions DEP-MCI patients showed moderate clinical response to sertraline treatment. When responders were compared to non-responders, cognitive improvement was limited to one measure of attention and executive function. Overall, there was little cognitive improvement with antidepressant treatment. The findings indirectly suggest that lack of improvement in cognition following treatment of depression in DEP-MCI patients may be associated with increased risk of meeting diagnostic criteria for dementia during follow-up.

description: Within the framework of light-front field theory, we reassess the electromagnetic form factors of the pion and kaon. Comparison with experiment is made for the full range of momentum transfer, q^2<0, including recent data. The light-front model's single regulator mass, m_R, of the \bar qq bound-state vertex function is initially adjusted to reproduce the weak decay constants, f_π and f_K, and both meson's charge radii, r_π and r_K. We study the behavior of these observables under variation of the quark masses and find an optimized parameter set, m_u=m_d, m_s and m_R, for which they are in sensibly better agreement with experiment than in a previous analysis; a feature also observed for the elastic form factors, in particular at small q^2. This model refinement is important in view of an extension to vector and heavy-light mesons.

description: A previous study of reference abilities and cortical thickness reported that association between reference abilities and cortical thickness summarized over large ROIs suppressed was suppressed after controlling for mean cortical thickness and global cognition. In this manuscript, we showed that preserving detailed spatial patterns of cortical thickness can identify reference-ability-specific association besides the association explained by global cognition and mean cortical thickness. We identified associations between cortical thickness and 3 cognitive reference abilities after controlling for mean thickness, global cognition, and linear chronological age: (1) memory, (2) perceptual speed, and (3) vocabulary. Global cognition was correlated with mean overall thickness but also was found to have a regionally specific pattern of associations. Nonlinear associations between cortical thickness and cognition were not observed, neither were nonlinear age effects. Age-by-thickness interactions were also absent. This implies that all thickness-cognition relations and age associations are independent of age and that consequently no age range is inherently special, since brain-behavioral findings are invariant across the whole age range.
Yan gaa duuneek : an examination of Indigenous transformational leadership pedagogies in BC higher education
Creators: name: Ormiston, Todd Lee
Publisher: name: University of British Columbia
Year: 2012

description: This dissertation explores transformational Indigenous leadership pedagogies in higher education through a study at the University of Victoria. Four students, six Indigenous faculty, and four elders were interviewed to explore traditional concepts of Indigenous leadership and how they are being applied today within post-secondary education. Key challenges to maintaining an Indigenous way of knowing while being in the academy, and the ways in which students, faculty and elders are dealing with those tensions are explored. What emerged from the interviews was the importance of living cultural and traditional teachings, a commitment to building and maintaining relationships and the responsibility to self -determination of Indigenous people, communities and Nations. This research is grounded in Indigenous theory through Tlingit philosophies, the Medicine Wheel and my Canoe Journey.

description: Let $\GroupG$ be a connected reductive algebraic group, $\GroupH \subsetneq \GroupG$ a reductive subgroup and $\GroupT \subset \GroupG$ a maximal torus. It is well known that if charactersitic of the ground field is zero, then the homogeneous space $\GroupG/\GroupH$ is a smooth affine variety, but never an affine space. The situation changes when one passes to double coset varieties $\dcosets{\GroupF}{\GroupG}{\GroupH}$. In this paper we consider the case of $\GroupG$ classical and $\GroupH$ connected spherical and prove that either the double coset variety $\dcosets{\GroupT}{\GroupG}{\GroupH}$ is singular, or it is an affine space. We also list all pairs $\GroupH \subset \GroupG$ such that $\dcosets{\GroupT}{\GroupG}{\GroupH}$ is an affine space.

description: Cognitive decline in dementia does not correspond precisely to the amount of neurodegeneration in the brain. This discrepancy in brain damage and its clinical manifestation has been explicated by the concept of reserve. Brain reserve inferred from the brain size had moderate success in explaining the discrepancy, and numerous studies have reported the effects of education supporting cognitive reserve. Yet the neural substrates of reserve have been elusive. Utilizing optimized voxel-based morphometry, we have identified brain regions that were significantly smaller in individuals with low cognitive performance (LCP) compared to those with normal cognitive performance (NCP) in community-residing non-demented elderly people both with low educational attainment. It was assumed that the cognitive performance in this population reflected long-standing cognitive functioning of the individual, possibly the reserve, based on their stable follow-up performance and clinical interviews. Bilateral precuneus, right superior frontal gyrus and left middle frontal gyrus were smaller in individuals with LCP. Further, the LCP individuals had weaker correlation between the gray matter volume of those regions and the rest of the cortex. On the other hand, volume of these regions was more tightly correlated with the K-DRS Total score in these individuals. Finally, an outcome study of the community sample from which this study's participants were recruited from reported five times higher risk of dementia in the LCP group. Precuneus and prefrontal cortex are proposed as key sites comprising the neural substrates that underlie the reserve.

description: Using airglow imagers, a particular type of gravity wave event called a mesospheric bore was observed over Germany and the observation was complemented by 2D Direct Numerical Simulation of the Navier-Stokes equations under Boussinesq approximation. The inclusion of the wind in addition to temperature, led to the generation of secondary instabilities previously reported in observations of both bores and solitons. The extension of the existing simulation to 3D showed that the dynamics are also influenced by the generation of these instabilities in the transverse direction to the propagation.
