How we came to stay : narratives of social workers in remote northern regions of British Columbia
Creators: name: Pierce, Joanna
Publisher: name: University of British Columbia
Year: 2017

description: This research explores the unfolding process of how four social workers living and working in remote northern British Columbia, chose to stay. Social work practice in rural, remote, and northern areas is a topic that has been widely explored in the literature. To date, efforts to increase recruitment and retention of social workers to these areas remain a concern and researchers continue to investigate aspects of practice in these regions. Previous exposure to life in the north is noted in the literature as one feature that supports workers with their transition, or commitment to, a northern location and therefore increases the likelihood a worker may stay longer-term (Cameron, 2010). In response to the need to understand how some social workers come to remain in remote northern place (Graham et al., 2008; Zapf, 2009), this study is completed applying narrative inquiry. Departing somewhat from current research focused on elements of job satisfaction, this research approaches the topic area through concepts of spatiality and how people come to bond with, and attach to, particular places, eventually identifying such places as ‘home’. The four narrated stories of remote northern social work in this thesis provide a different way in which to understand remote northern social work; one that reveals details of the process of coming to stay in a new manner.

description: Next-generation sequencing has yielded a vast amount of cattle genomic data for global characterization of population genetic diversity and identification of genomic regions under natural and artificial selection. However, efficient storage, querying, and visualization of such large datasets remain challenging. Here, we developed a comprehensive database, the Bovine Genome Variation Database (BGVD). It provides six main functionalities: gene search, variation search, genomic signature search, Genome Browser, alignment search tools, and the genome coordinate conversion tool. BGVD contains information on genomic variations comprising ~60.44 M SNPs, ~6.86 M indels, 76,634 CNV regions, and signatures of selective sweeps in 432 samples from modern cattle worldwide. Users can quickly retrieve distribution patterns of these variations for 54 cattle breeds through an interactive source of breed origin map, using a given gene symbol or genomic region for any of the three versions of the bovine reference genomes (ARS-UCD1.2, UMD3.1.1, and Btau 5.0.1). Signals of selection sweep are displayed as Manhattan plots and Genome Browser tracks. To further investigate and visualize the relationships between variants and signatures of selection, the Genome Browser integrates all variations, selection data, and resources, from NCBI, the UCSC Genome Browser, and Animal QTLdb. Collectively, all these features make the BGVD a useful archive for in-depth data mining and analyses of cattle biology and cattle breeding on a global scale. BGVD is publicly available at http://animal.nwsuaf.edu.cn/BosVar.

description: Coherent radio emission from extensive air showers at MHz frequencies is exploited. The sensitivity to the mass composition as well as the reconstruction of the energy of the primary particle are investigated by leveraging the features of the radio lateral distribution function. Based on (REAS3)-simulation predictions, a method is developed and directly applied on LOPES measurements. The possibility to reconstruct both energy and Xmax using radio data, with relatively high precision, is showed.
Removal of Chromium from Water using Manganese Oxide Based Adsorbents: Adsorption of Cr(III) and Cr(VI)

description: The removal of chromium from water down to environmentally acceptable levels is required because of the toxicity of this contaminant species. The removal of chromium from water should be achieved in an effective manner using relatively simple and inexpensive technology. Various technologies such as ion exchange, membrane filtration, adsorption and reduction-filtration-precipitation have been employed for removal of chromium from water. Adsorption is considered as a relatively simple and effective technology with low operational cost. Metal oxides such as manganese oxides have commonly been used as potential adsorbents for the removal of heavy metals. However, the application of pure manganese oxides as viable adsorbents or filter media in a flow-through (adsorber) column system is limited due to the low hydraulic conductivity and extant colloidal form of the pure manganese oxides. Manganese-coated sand (MCS) has exhibited a considerably appreciable adsorption capacity toward several heavy metal species which are present in water as cations or as oxyanions. In this study, we focused on synthesizing and evaluating a novel MCS sorbent with a high hydraulic conductivity as a potential sorbent for removal of two chromium species [Cr(III) and Cr(VI)] from water. In order to investigate the adsorption mechanism and interactions between the two chromium species with the MCS sorbent, we employed several surface characterization techniques to analyze the crystallinity and surface oxides on the surface of the MCS sorbent, surface charge, surface elemental composition and oxidation states of manganese and chromium before and after adsorption. A surface complexation model was developed for the adsorption process based on the experimental adsorption data and surface characterization results. A sustainability assessment was performed to compare the sustainability of the MCS adsorber system with two other technologies used for the removal of chromium from water.
Inertia and Learning in Physician Prescribing Behavior

description: Pharmaceutical spending in the United States represents 10 percent of national health expenditure. There is a vigorous policy debate on lowering pharmaceutical spending, in which generics play a large role. Many institutional features encourage generic drugs as the default choice once they are available. However, the switch to generic drugs is slow, which is costly to patients and insurers. I estimate the effects of physician and patient familiarity with brand-name drugs on generic utilization for atypical antipsychotics. Using claims data from a large, national insurer, I show that physicians familiar with the drug class before generic entry are 16 percent more likely to prescribe the brand-name drug after generic entry. I then address two possible causes of choice persistence in brand-name drug prescriptions—switching costs and learning—using a structural demand model. Results show that physicians incur large switching costs, which are slightly reduced as learning occurs through additional prescribing of the drug. Counterfactual simulations show that policies that reduce physician switching costs, such as removing the availability of brand-name drugs once the generic enters, can increase welfare by $31 per prescription and decrease average patient copays.

description: We study a model of self propelled particles exhibiting run and tumble dynamics on lattice. This non-Brownian diffusion is characterised by a random walk with a finite persistence length between changes of direction, and is inspired by the motion of bacteria such as E. coli. By defining a class of models with multiple species of particle and transmutation between species we can recreate such dynamics. These models admit exact analytical results whilst also forming a counterpart to previous continuum models of run and tumble dynamics. We solve the externally driven non-interacting and zero-range versions of the model exactly and utilise a field theoretic approach to derive the continuum fluctuating hydrodynamics for more general interactions. We make contact with prior approaches to run and tumble dynamics off lattice and determine the steady state and linear stability for a class of crowding interactions, where the jump rate decreases as density increases. In addition to its interest from the perspective of nonequilibrium statistical mechanics, this lattice model constitutes and efficient tool to simulate a class of interacting run and tumble models relevant to bacterial motion, so long as certain conditions (that we derive) are met.

The momentum distribution is measured using Bragg spectroscopy and an effective coherence length of the whole ensemble is defined. In addition, we propose and demonstrate that time-of-flight absorption imaging can be used as a simple probe to directly measure the coherence-length of 1D gases in the regime where phase-fluctuations are strong. This method is suitable for future studies such as investigating the effect of disorder on the phase coherence.

The Importance of Contextual Factors in Program Development and Evaluation – A Case Study
Creators: name: Halverson, Amy L.
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: Several conceptual frameworks discuss the importance of context in educational program development and evaluation. The interpretation of context varies among the different conceptual frameworks. Additionally, there are limited examples in the literature how one can identify context, of how educational programs should be adapted to relevant contexts and how context may inform and affect program evaluation. We collected geographic information, course evaluation results and follow-up survey data related to a skills course for rural surgeons offered by the American College of Surgeons. This course provides an illustrative example of how contextual factors such as current trends, the learning environment, learners’ baseline behaviors, and learners’ practice setting influence learning and subsequent implementation of new knowledge, attitudes and skills into clinical practice. Educational interventions should have a learner-centric approach to content that considers the learners’ baseline experience, self-confidence and potential barriers to implementation of newly learned techniques. Educators may keep content new and relevant by keeping abreast of current popular topics related to surgical patient safety. Additionally, the introduction of new technology or instrumentation is an opportunity for education and training. Educators should realize that an outstanding curriculum may be derailed by logistical issues in the educational setting. We recommend that educators create a checklist of necessary resources, including space, personnel and equipment, and develop contingency plans for unexpected problems.
Coincident count rates in absorbing dielectric media

description: A study of the effects of absorption on the nonlinear process of parametric down conversion is presented. Absorption within the nonlinear medium is accounted for by employing the framework of macroscopic QED and the Green tensor quantization of the electromagnetic field. An effective interaction Hamiltonian, which describes the nonlinear interaction of the electric field and the linear noise polarization field, is used to derive the quantum state of the light leaving a nonlinear crystal. The signal and idler modes of this quantum state are found to be a superpositions of the electric and noise polarization fields. Using this state, the expression for the coincident count rates for both Type I and Type II conversion are found. The nonlinear interaction with the noise polarization field were shown to cause an increase in the rate on the order of 10^{-12} for absorption of 10% per cm. This astonishingly small effect is found to be negligible compared to the decay caused by linear absorption of the propagating modes. From the expressions for the biphoton amplitude it can be seen the maximally entangled states can still be produced even in the presence of strong absorption.

Transcriptomics of post-anthesis colour change in Lotus
Creators: name: Boehm, Mannfred M. A.
Publisher: name: University of British Columbia
Year: 2017

description: Post-anthesis colour change (PACC) is widely thought to be an adaptation to signal floral viability to pollinators, and may be a developmental pre-pattern for bird pollination in Lotus. Lotus filicaulis and Lotus sessilifolius are insect-pollinated herbaceous legumes with flowers that open yellow, shift to orange and finally, red. This thesis examines the ecological and molecular basis for floral colour change in these Lotus species. L. filicaulis was cultivated in a glasshouse from which pollinating insects (bees) were excluded, and the rate of colour change was recorded in both unpollinated and manually pollinated flowers. Unpollinated flowers from both the yellow stage and red stage were sampled for sequencing. The transcriptomes of L. filicaulis and L. sessilifolius of both colour stages were analyzed for differentially expressed genes and enriched ontologies. Pollination significantly accelerates PACC in L. filicaulis, consistent with the hypothesis that PACC increases pollination efficiency by directing pollinators to unpollinated flowers. RNA-seq results show the synchronized upregulation of the entire cyanidin biosynthesis pathway in the red stage of PACC of both Lotus species – possibly at the expense of adjacent pathways competing for the same substrate. This thesis is the foundation for understanding the molecular evolution of PACC in Lotus and will be useful in testing the hypothesis that PACC is a preadaptation to bird pollination in Lotus.

description: We address the question whether observables of an exactly solvable model of electrons coupled to (optical) phonons relax into large time stationary state values and investigate if the asymptotic expectation values can be computed using a stationary density matrix. Two initial nonequilibrium situations are considered. A sudden quench of the electron-phonon coupling, starting from the noninteracting canonical equilibrium at temperature T in the electron as well as in the phonon subsystems, leads to a rather simple dynamics. A richer time evolution emerges if the initial state is taken as the product of the phonon vacuum and the filled Fermi sea supplemented by a highly excited additional electron. Our model has a natural set of constants of motion, with as many elements as degrees of freedom. In accordance with earlier studies of such type of models we find that expectation values which become stationary can be described by the density matrix of a generalized Gibbs ensemble which differs from that of a canonical ensemble. For the model at hand it appears to be evident that the eigenmode occupancy operators should be used in the construction of the stationary density matrix.

description: The level of control that one has over neutral molecules in beams dictates their possible applications. Here we experimentally demonstrate that state-selected, neutral molecules can be kept together in a few mm long packet for a distance of over one mile. This is accomplished in a circular arrangement of 40 straight electrostatic hexapoles through which the molecules propagate over 1000 times. Up to 19 packets of molecules have simultaneously been stored in this ring structure. This brings the realization of a molecular low-energy collider within reach.
A Wavelet Smoothing Approach to Reducing Bias in Structural Vector Autoregressions
Creators: name: Kelley, Michael P
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: This study proposes a modification of the Blanchard Quah method of obtaining identification in Structural Vector Autoregressions (SVAR) using long run restrictions. Employing a discrete wavelet transform (DWT) to filter out high frequency variation, it obtains a better estimate of the long run effect matrix and substantially reduces bias when tested on a simulated dataset. This modification addresses the criticism of bias in the Blanchard Quah method due to lag truncation. By filtering the high frequency variation when estimating the long run effects matrix using ordinary least squares, I push the bias towards the high frequency region where it will not bias the estimate of the long run effects matrix. I test this method against the standard method using a monte carlo experiment utilizing a two variable real business cycle model and show much lower bias than the standard method. The modified method that I refer to as Wavelet BQ is then applied to the data used to parameterize that real business cycle model and rejects the parameterization. Next, I examine data from 4 small open economies to test Dornbush's overshooting model. Wavelet BQ shows responses for all 4 countries that are of the magnitude and shape predicted by Dornbush's overshooting model. The standard method (Standard BQ) has the right shape and direction but the effect sizes are biased upward toward 0 and about half the magnitude as the ones estimated by Wavelet BQ.

description: It is theoretically shown that, in the four-fold symmetric d-wave superconducting phase, a paramagnetic pair-breaking (PPB) enhanced sufficiently by increasing the applied magnetic field induces not only the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconducting state but also an incommensurate antiferromagnetic (AFM) order with Q-vector parallel to a gap node. This AFM ordering tends to occur only below H_{c2} at low temperatures, i.e., in the presence of a nonvanishing superconducting energy gap $Δ$ rather than in the normal phase. Through a detailed study on the resulting AFM order and its interplay with the FFLO spatial modulation of $Δ$, it is argued that the strange high field and low temperature (HFLT) superconducting phase of CeCoIn_5 is a coexisting phase of the FFLO and incommensurate AFM orders, and that this PPB mechanism of an AFM ordering is also the origin of the AFM quantum critical fluctuation which has occurred close to H_{c2}(0) in several unconventional superconductors including CeCoIn_5.

Historical Articles on the Plant Closing Movement, Industrial Retention Policies and Economic Development
Creators: name: O'Neill-Kohl, Sara K
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: Economic restructuring presents ongoing challenges for economic development planners. In particular, the 1970s and 1980s are well known for the hardships that economic dislocations inflicted on industrial workers and their communities. Most scholarly and applied work invoking this period is grounded in a contemporary understanding of the inevitability of global economic change, and the limitations this presents for local economic development policy and practice. This dissertation takes a different approach. It maintains that we cannot understand the current boundaries of our discipline without first traveling back to a time before they were so firmly in place. Thus, the topic of this dissertation is a lesser known aspect of the deindustrialization story: how communities fought back. The “plant closing movement” was made up of coalitions of religious and community groups, unions, and progressive local officials that arose across the country in the 1970s and 1980s to resist and reverse industrial job loss, mobilizing both direct action and policy. The dissertation, a collection of three articles, asks how the successes and failures of the plant closing movement have shaped ongoing progressive efforts in economic development planning. Together, the articles reveal a story of the ideological restraint of policy alternatives. By directing attention to the process by which economic decisions are determined to be “public” or “private”, and how those decisions have changed over time, the work combats the notion that today’s formation of economic development is a natural or inevitable state.

description: We analyze the partition function of the dimer model on an $\mathcal{M} \times \mathcal{N}$ triangular lattice wrapped on torus obtained by Fendley, Moessner and Sondhi [Phys. Rev. B \textbf{66}, 214513 (2002)]. From a finite-size analysis we have found that the dimer model on such a lattice can be described by conformal field theory having central charge $c=1$. The shift exponent for the specific heat is found to depend on the parity of the number of lattice sites $\mathcal{N}$ along a given lattice axis: e.g., for odd $\mathcal{N}$ we obtain the shift exponent $λ=1$, while for even $\mathcal{N}$ it is infinite ($λ=\infty$). In the former case, therefore, the finite-size specific-heat pseudocritical point is size dependent, while in the latter case, it coincides with the critical point of the thermodynamic limit.

Physiological, transcriptomic and genomic mechanisms of thermal adaptation in Oncorhynchus mykiss
Creators: name: Chen, Zhongqi
Publisher: name: University of British Columbia
Year: 2017

description: Given the rate and magnitude of the ongoing global warming, there is some urgency to understand the underlying mechanism of thermal adaptation to evaluate and predict the ecological consequences. This thesis used Oncorhynchus mykiss from different thermal regimes to examine thermal adaptation at physiological, transcriptomic and genomic levels. Thermal tolerance was examined in three redband trout (O. mykiss gairdneri) populations from warm desert and cool montane climates (Idaho, USA), as well as in a domesticated rainbow trout (O. mykiss) strain raised in a thermally challenging environment for over 19 generations (Western Australia, Australia). Acclimated to 15°C, the desert redband trout had the highest critical thermal maximum (CTMAX; 29.7°C) and maintained an almost constant absolute aerobic scope (AAS) across a broader range of test temperatures (12-24°C) than seen in other strains, but had the lowest peak AAS, suggesting a tradeoff between thermal performance and tolerance. Western Australian rainbow trout had the highest AAS, even when tested at 21°C, which may be a result of hatchery selection for thermal performance. Although the rate transition temperatures for maximum heart rate (Arrhenius breakpoint and arrhythmia temperature for fH,max) were similar among all populations, fH,max was the highest in the desert redband trout population at all temperatures. Cardiac RNA sequencing revealed different patterns of gene regulation among redband trout populations during acute warming. Many genes had different mRNA abundances between populations due to constitutive and induced expression, and the number of differentially expressed genes among populations was positively correlated to the genetic distance, suggesting intraspecific cellular regulatory strategies in response to acute warming. Population and quantitative genetic studies identified potential genomic markers for thermal adaptation. A total of twenty-one loci were putatively under positive thermal selection (“outliers”). In addition, genotypes of some outlier loci had significantly different CTMAX. Genome-wide association study identified twelve loci that were significantly associated with individual CTMAX. Altogether, results in my dissertation demonstrated the capacity of thermal adaptation in O. mykiss populations at multiple organismal levels. This data lays a foundation to improve our understanding on the potential impact of global warming on wild aquatic populations.

description: Since the Spring of 2020 and due to the Pandemic, the massive transition to online spaces has magnified the issue of the influence of digital regulation on the choice of behavior on the Internet as a special cultural and symbolic environment. The article presents a theoretical analysis of regulatory mechanisms in the digital environment. It discusses the main problem of choosing behavioral models in cyberspace. The purpose of the research is thus to systematize psychological approaches to the study of the regulation of human behavior as it is translated to the digital environment. The research was carried out by a qualitative methodology of discussions among teachers and students. Three problem areas of behavior regulation were identified, namely the acceptance of responsibility, the externalization of motivation, and the simplification of choice. These are reflected in the evolution of regulatory mechanisms for the formation of value judgments, the fragmentation and breaking of chains of activity, and the feedback system or social control which acquire a quantitative dimension in digital space. The limitations of the results obtained are due to the qualitative methodology that was adopted for the empirical part of the research, that is, with its concentration on the educational sphere, with the period of the pandemic and with the stress that was due to the overall transition to online learning. Conceptually, however, there are social implications in regard to the discovery of public or state interventions, especially the regulation of activity of social media, of institutions functioning online and of individual and group (households, institutions) users. The original value of the research relates to the systemic analysis of psychological approaches to the problem areas of regulation of human behavior in digital space. The study substantiates the need for independent regulatory activity as a special type of governance of behavior in the digital environment, contradicting the “Google doctrine“ that presupposes natural self-regulation and self-organization on the Internet.

2+1d quantum field theories in large N limit
Creators: name: Omid, Hamid
Publisher: name: University of British Columbia
Year: 2017

description: In Chapter 1, we present a brief introduction to the tight-binding model of graphene and show that in the low-energy continuum limit, it can be modeled by reduced QED₂₊₁ . We then review renormalization group technique which is used in the next chapters. In Chapter 2, we consider a quantum field theory in 3+1d with the defect of a large number of fermion flavors, N. We study the next-to-leading order contributions to the fermions current-current correlation function by performing a large N expansion. We find that the next-to-leading order contributions 1/N to the current-current correlation function is significantly suppressed. The suppression is a consequence of a surprising cancellation between the two contributing Feynman diagrams. We calculate the model's conductivity via the Kubo formula and compare our results with the observed conductivity for graphene. In Chapter 3, we study graphene's beta function in large N. We use the large N expansion to explore the renormalization of the Fermi velocity in the screening dominated regime of charge neutral graphene with a Coulomb interaction. We show that inclusion of the fluctuations of the magnetic field lead to a cancellation of the beta function to the leading order in 1/N. The first non-zero contribution to the beta function turns out to be of order 1/N². We perform a careful analysis of possible infrared divergences and show that the superficial infrared divergences do not contribute to the beta function. In Chapter 4, we study the phase structure of a Φ⁶ theory in large N. The leading order of the large N limit of the O(N) symmetric phi-six theory in three dimensions has a phase which exhibits spontaneous breaking of scale symmetry accompanied by a massless dilaton. In this chapter, we show that this “light dilaton” is actually a tachyon. This indicates an instability of the phase of the theory with spontaneously broken approximate scale invariance. We rule out the existence of Bardeen-Moshe-Bander phase. In this thesis, we show that Large N expansion is a powerful tool which in regimes that the system is interacting strongly could be used as an alternative to coupling expansion scheme.

description: Cystathionine γ-lyase (CSE) has become a target of interest in recent years via its ability to synthesize hydrogen sulfide. However, lack of suitable inhibitors has prevented scientists from properly delineating the role of CSE in disease and disease state, therefore hindering the progress of this field. This study aimed to revise commonly known CSE inhibitors, such as L-PAG, by using three distinct enzymatic assays as well as several CSE substrates. Moreover clavulanic acid was identified as a novel inhibitor for CSE for the first time. Although L-PAG remains as the best CSE inhibitor, this study has been able to clarify discrepancies of CSE inhibition found within the literature, as well as providing a better mechanistic view of this enzyme. By focusing on the mechanism of CSE (via γ and β-elimination) as well as substrate preference, the work shown here has provided a basis that could aid in the future discovery of more selective potent inhibitors. In addition, this study has shown the beneficial effects that CSE can have under oxidative stress. By using oxidative stress models such as excess of 4-hydroxynonenal (HNE) and 4-oxononenal (ONE), two known biomarkers of oxidative stress, this work has shown that CSE is able to create powerful antioxidants from several substrates, which can scavenge HNE and ONE therefore preventing protein crosslinking. Overall, this work shows the therapeutic potential of CSE, from its inhibition, to its ability to create powerful antioxidants under oxidative stress.

description: Using a combination of analytical and numerical techniques, we show that chaos in globally-coupled identical dynamical systems, be they dissipative or Hamiltonian, is both extensive and sub-extensive: their spectrum of Lyapunov exponents is asymptotically flat (thus extensive) at the value $λ_0$ given by a single unit forced by the mean-field, but sandwiched between sub-extensive bands containing typically $\mathcal{O}(\log N)$ exponents whose values vary as $λ\simeq λ_\infty + c/\log N$ with $λ_\infty \neq λ_0$.

description: Zigzag graphene nanoribbons patterned on graphane are studied using spin-polarized ab initio calculations. We found that the electronic and magnetic properties of the graphene/graphane superlattice strongly depends on the degree of hydrogenation at the interfaces between the two materials. When both zigzag interfaces are fully hydrogenated, the superlattice behaves like a freestanding zigzag graphene nanoribbon, and the magnetic ground state is antiferromagnetic. When one of the interfaces is half hydrogenated, the magnetic ground state becomes ferromagnetic, and the system is very close to being a half metal with possible spintronics applications whereas the magnetic ground state of the superlattice with both interfaces half hydrogenated is again antiferromagnetic. In this last case, both edges of the graphane nanoribbon also contribute to the total magnetization of the system. All the spin-polarized ground states are semiconducting, independent of the degree of hydrogenation of the interfaces. The ab initio results are supplemented by a simple tight-binding analysis that captures the main qualitative features. Our ab initio results show that patterned hydrogenation of graphene is a promising way to obtain stable graphene nanoribbons with interesting technological applications.

description: We present a direct measurement of the mass difference between top and antitop quarks (dm) in lepton+jets top-antitop final states using the "matrix element" method. The purity of the lepton+jets sample is enhanced for top-antitop events by identifying at least one of the jet as originating from a b quark. The analyzed data correspond to 3.6 fb-1 of proton-antiproton collisions at 1.96 TeV acquired by D0 in Run II of the Fermilab Tevatron Collider. The combination of the e+jets and mu+jets channels yields dm = 0.8 +/- 1.8 (stat) +/- 0.5 (syst) GeV, which is in agreement with the standard model expectation of no mass difference.

description: Analysts of world politics routinely ask what a ‘rising’ China will want and what it will do. In this paper, we ask a different question: what is China? In dominant accounts of China's rise, adopting a Weberian model of the state and methodological nation-statism in analysis, the answer to this question is theoretically over-determined: China is either a rising power, a strong state, or it is weak and fragmenting. Against Weberian perspectives, we make two moves which together produce a different constitutive account of China’s rise and what it means. First, we adopt an historical materialist conception of the state, drawn from internationalization of the state theory. Second, we focus empirically on the Chinese peasantry which, despite its centrality to Chinese economic development, is usually either marginal or invisible in analysis of China's rise. Such an account is both conceptually superior to Weberian accounts by integrating analysis across scales, escaping the territorial trap, and also empirically richer in being able to account for more of the available evidence of China's rise, its dynamics and implications. Specifically, it enables us to produce an integrated account of rural and urban developments, as together constitutive of the internationalization of the Chinese state.

description: The ttbar spin correlation at production is a fundamental prediction of QCD and a potentially incisive test of new physics coupled to top quarks. We measure the ttbar spin state in ppbar collisions at sqrt(s) = 1.96 TeV using 1001 candidate events in the lepton plus jets decay channel reconstructed in the CDF II detector. In the helicity basis, for a top-quark mass of 172.5 GeV/c^2, we find a spin correlation coefficient kappa = 0.60 +/- 0.50 (stat) +/- 0.16 (syst), consistent with the QCD prediction, kappa ~= 0.40.

description: Modern programming paradigms heavily rely on the concept of parallel programming and multi-threading. As a consequence, it has been possible to observe an increase in the need to efficiently communicate, synchronize and share data structures between threads. Conventional synchronization mechanisms are based on the concept of locking. In general, such approaches have an advantage when there is low contention over the lock; while, on the other hand, under conditions of high contention, delegation as Fast Fly Weight Delegation has been proven to provide better performance in terms of both throughput and latency. Nevertheless, State Of the Art implementation of delegation as Gepard requires to dedicate one, or possibly more, cores to act as servers (the concept of server and how delegation works are going to be explained in the following Chapters). Often such servers are not very busy, instead they are just busy-waiting, until some work arrives. We show how this limitation can be bypassed in designated delegation with little or no overhead and how our solution enables for an efficient implementation of a variation of standard delegation: flat delegation. We evaluate designated and flat delegation on a Fetch-And-Add benchmark under different load conditions and report latency and throughput results comparing against Gepard and conventional lock mechanisms.

description: Although autism spectrum disorders (ASDs) have long been known to have a strong heritability, the genetic basis of these disorders has remained largely elusive. Hundreds of genes have been linked to ASDs, but most of them only contribute a small increase in risk. In 2009, a genome-wide association study identified Semaphorin 5A (SEMA5A) as a novel autism susceptibility gene. Sema5A is a member of the Semaphorin family consisting of secreted and membrane-associated proteins characterized by the Sema domain. Although initially identified as axon guidance cues, Semaphorins have been found to play numerous key roles in the development and function of the nervous system. Here, I provide evidence that Sema5A, along with Sema5B, regulates dendritic morphology and excitatory synaptic elimination in hippocampal neurons. The overexpression of Sema5A/Sema5B negatively impacted dendrite complexity and reduced excitatory synapse density without affecting inhibitory synapses, in contrast the knockdown of Sema5A/Sema5B increased excitatory synapse density. I also investigated the relationship between Sema5A/Sema5B and activity-dependent plasticity including long-term potentiation (LTP) and long-term depression (LTD), which are cellular models of learning and memory. It was demonstrated that the overexpression of Sema5A/Sema5B attenuated the LTP-mediated increase of synapse density, whereas the knockdown of Sema5A/Sema5B blocked the LTD-mediated decrease of synapse density. Furthermore, soluble Sema5A treatment altered the surface expression of the AMPA receptor subunit GluA1 with total level of GluA1 unchanged. Finally, I examined the signaling mechanisms of Sema5A-mediated synapse elimination and plasticity. I found that in vitro Sema5A signalled through two members (Plexin A1 and Plexin A2) of the Plexin family, which are known as the neuronal receptors for the Semaphorin family. Moreover, TAG-1, a cell adhesion molecule also known as Contactin-2, was necessary for the function of Sema5A and Sema5B. Lastly I found that ALLN, an inhibitor of protease calpain, significantly rescued Sema5A-mediated synapse elimination, suggesting that calpain was downstream of Sema5A signaling in hippocampal neurons. Thus, my data revealed a new role for class 5 Semaphorins in synapse density and plasticity, and may therefore provide insights into the critical roles of Sema5A in the general mechanisms of circuit formation and the specific etiology of ASDs.
