Developing effective knowledge management systems
Creators: name: Nevo, Dorit
Publisher: name: University of British Columbia
Year: 2009

description: Knowledge Management Systems (KMS) are computerized systems intended to support the management and application of organizational knowledge. Despite the many potential benefits from KMS> industry reports show that companies are having difficulties in realizing these benefits. This dissertation sets out to identify the reasons for those difficulties - from a requirements analysis point of view - and to propose a way to improve the design of KMS in order to enhance their benefits to companies. We develop a theory-based approach to the evaluation of Knowledge Management Systems and identify the main shortfalls of existing systems. The findings show two inter-related problems. First, the lack of a conceptual model such as an organizational ontology or of additional knowledge about the knowledge might inhibit KMS ability to support specific organizational KM processes. Second - the lack of an integrated KM product reduces organization's ability to attain an overall solution for the management of organizational knowledge. In addition, the analysis pinpoints the inability of current technology to support effective management of tacit knowledge - an important aspect of KMS design. In the second part of the dissertation we focus on one of the problems identified - namely, the lack of a unified meta-knowledge set - and identify the specific meta-knowledge that should be incorporated into the design of KMS. The expected benefits from the inclusion of meta-knowledge are better management of organizational memory and enhanced adoption of knowledge by KMS users. We conduct an empirical investigation - using conjoint analysis - to identify specific attributes of knowledge and of knowledge sources that individuals take into account when making their knowledge use decision, and propose that these attributes should be included as meta-knowledge in the KMS design. The results indicate that the 'accuracy' and 'relevance' of the knowledge are the top two important attributes in the knowledge selection decision and 'extent of knowledge' and 'trustworthiness' are the top two important attributes in the selection of a knowledge source. In addition the results show that knowledge plays a slightly more important role than knowledge source in the overall decision. Finally, several demographic and contextual variables - such as the knowledge search task and organization size - are shown to affect the importance of different attributes in the overall evaluation of knowledge and of knowledge source by individuals.

description: Antiferromagnet materials have recently gained renewed interest due to their possible use in spintronics technologies, where spin transport is the foundation of their functionalities. In that respect metallic antiferromagnets are of particular interest, since they enable complex interplays between electronic charge transport, spin, optical, and magnetization dynamics. Here we review phenomena where the metallic conductivity provides unique perspectives for the practical use and fundamental properties of antiferromagnetic materials.

description: We use Bayesian Markov Chain Monte Carlo methods to investigate the linkage between the volatility of ethanol security prices and the uncertainty surrounding the profitability of ethanol production and the price variations of non-ethanol energy securities. The joint evolution of return and volatility is modeled as a stochastic process that incorporates jumps in both return and volatility. While a strong and significant correlation is found between the volatility of ethanol securities and profit uncertainty from June 2005 to July 2008, the dynamic pattern of ethanol stock volatility is strikingly similar to that of the S&P 500 energy sector index in the more recent period. Our evidence lends support to the findings in the literature on rational learning from uncertainty in determining the equity price and volatility during the adoption and development of a technological innovation.
Measurement of mass and width of the excited charmed meson states $D_1^0$ and $D_2^{*0}$

Year: 2005
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: This paper describes a measurement of the mass and of the width of two neutral narrow resonances $D_10$ and $D_2^{0*}$, both composed of a charm quark and an up antiquark. The difference with respect to the well-known resonance $D0$, also neutral and with the same quark composition, is that the two quarks have an orbital momentum 1, which increases their binding energy. Therefore the mass is larger than that of the $D0$. Since the relative orientation of the spin is the same, in the limit of very large charm mass, the masses of these resonances should be the same; their small difference is predicted by theory and therefore important to measurement to distinguish the different models. These states have been observed in their decay into a kaon and three pions; two of these particles are required to originate from a displaced vertex with respect to the primary interaction vertex, to account for the longer lifetime of the charmed mesons. The resonances parameters have been extracted using a fitting procedure accounting for the expected resonance shape, including effects from detector resolution and background, providing a new best single measurement of the $D_10$ and $D_2^{0*}$ masses and a competitive measurement of their widths.

description: This paper investigates the role that aspects of the physical environment play in determining health outcomes in adults as measured by body mass index (BMI). Using spatial econometric techniques that allow for spatial spillovers and feedback processes, this research specifically examines how differing levels of access to large chain grocers has on individual health outcomes. While other studies have investigated the impact of proximity to food retailers, the point-coordinate data used in this paper is uniquely suited to spatial econometric estimation at the individual level. In addition to modeling spatial dependence and allowing for unobserved neighborhood effects, the flexibility of the model is increased by incorporating potential spatial heterogeneity between wealthier and lower-income neighborhoods. Using survey responses tied to geographic location, demographic, behavioral, and access to chain grocers, this study finds evidence of spatial dependence pointing to locational impacts on BMI. The effect on individual health outcomes of retailer access improvements varies depending on neighborhood characteristics. Our findings suggest structural differences in the variation and sensitivity of BMI dependent jointly on individual and neighborhood characteristics.

description: We measure experimentally the rearrangements due to a small localized cyclic displacement applied to a packing of rigid grains under gravity in a 2D geometry. We analyze the evolution of the response to this perturbation by considering the individual particle displacement and the coarse grained displacement field, as well as the mean packing fraction and coordination number. We find that the displacement response is rather long ranged, and evolves considerably with the number of cycles. We show that a small difference in the preparation method (induced by tapping the container) leads to a significant modification in the response though the packing fraction changes are minute. Not only the initial response but also its further evolution change with preparation, demonstrating that the system still retains a memory of the initial preparation after many cycles. Nevertheless, after a sufficient number of cycles, the displacement response for both preparation methods converges to a nearly radial field with a 1/r decay from the perturbation source. The observed differences between the preparation methods seem to be related to the changes in the coordination number (which is more sensitive to the evolution of the packing than the packing fraction). Specifically, it may be understood as an effect of the breaking of local arches, which affects the lateral transmission of forces.

description: We address nonlocality of continuous variable systems in the presence of dissipation and noise. Three nonlocality tests have been considered, based on the measurement of displaced-parity, field-quadrature and pseudospin-operator, respectively. Nonlocality of twin beam has been investigated, as well as that of its non-Gaussian counterparts obtained by inconclusive subtraction of photons. Our results indicate that: i) nonlocality of twin beam is degraded but not destroyed by noise; ii) photon subtraction enhances nonlocality in the presence of noise, especially in the low-energy regime.

description: Macedonia, as a candidate country to the EU and a member of the WTO is in need of a comprehensive, transparent, and internationally comparable assessment of the support to agriculture in the country. OECD that has been measuring support to agriculture on a yearly basis, in its member countries as well as some other countries since the mid-1980s offers a good tool for such a task. The method is known for its most important indicator, the Producer Support Estimate (PSE). Using this method, data on Macedonian agricultural policy measures, in place – partly or entirely - for the period 1999 to 2004, have been gathered and categorized in order to arrive at an estimate of the level of support. This report presents the main findings of this assessment.

description: Let $L(s,χ)$ be the Dirichlet $L$-function associated to a non-principal primitive character $χ$ modulo $q$ with $3\le q \le 400\,000$. We prove a new explicit zero-free region for $L(s,χ)$: $L(s,χ)$ does not vanish in the region $\Re s \ge 1-\frac1{R \log \left(q\max(1,| \Im s|)\right) }$ with $R=5.60$. This improves a result of McCurley where $9.65$ was shown to be an admissible value for $R$.

description: This paper considers a class of qubit channels for which three states are always sufficient to achieve the Holevo capacity. For these channels it is known that there are cases where two orthogonal states are sufficient, two non-orthogonal states are required, or three states are necessary. Here a systematic theory is given which provides criteria to distinguish cases where two states are sufficient, and determine whether these two states should be orthogonal or non-orthogonal. In addition, we prove a theorem on the form of the optimal ensemble when three states are required, and present efficient methods of calculating the Holevo capacity.

description: Naturally occurring networks exhibit quantitative features revealing underlying growth mechanisms. Numerous network mechanisms have recently been proposed to reproduce specific properties such as degree distributions or clustering coefficients. We present a method for inferring the mechanism most accurately capturing a given network topology, exploiting discriminative tools from machine learning. The Drosophila melanogaster protein network is confidently and robustly (to noise and training data subsampling) classified as a duplication-mutation-complementation network over preferential attachment, small-world, and other duplication-mutation mechanisms. Systematic classification, rather than statistical study of specific properties, provides a discriminative approach to understand the design of complex networks.

Full computation of massive AGB evolution. I. The large impact of convection on nucleosynthesis

description: It is well appreciated that the description of overadiabatic convection affects the structure of the envelopes of luminous asymptotic giant branch (AGB) stars in the phase of ``hot bottom burning '' (HBB). We stress that this important uncertainty in the modeling plays a role which is much more dramatic than the role which can be ascribed, e.g., to the uncertainty in the nuclear cross-sections. Due to the role tentatively attributed today to the HBB nucleosynthesis as the site of self-enrichment of Globular Clusters stars, it is necessary to explore the difference in nucleosynthesis obtained by different prescriptions for convection. We present results of detailed evolutionary calculations of the evolution of stars of intermediate mass during the AGB phase. We follow carefully the nucleosynthesis at the base of the external convective region, showing that very different results can be obtained according to the presciption adopted to find out the temperature gradient within the instability regions. We discuss the uncertainties in the yields of the various chemical species and the role which these sources can play as polluters of the interstellar medium.

description: By duality approach, we study condensate mass of QCD vacuum via dilaton wall background in presence of parameter $c$ which represents the gluon condensation in holographic set up. First from Wilson line calculation we find $m^2_0$ (condensate parameter in mixed nonlocal condensation) whose behavior mimics that of QCD. The value of $m^2_0$ that we find by this approach, is in agreement with QCD data. In the second step we consider produced mass m via Schwinger effect mechanism in presence of parameter $c$. We show that generally gluon condensation contribute mass dominantly and produced mass via Schwinger effect is suppressed by $m_0$ .

description: The objective of this work was to analyze the cost allocation of improvements in river basins among the water users. It was used, as example, the Paraíba do Sul river basin, located in the states of Minas Gerais, São Paulo and Rio de Janeiro, and, as criteria of allocation of costs, they were used the volumes of water extracted and consumed, and the quantity of pollutants deposited in the basin area by water users. The methodology used consists of the rule of allocation known as Shapley value, which belongs to the cooperative branch of game theory. In the case of Paraíba do Sul river basin, the values found indicated that the urban users should pay the higher part of the costs of improvements, given that these users are responsible for most of the pollution in the basin area, being the reduction of water quality an important problem in this basin.

description: We report an improved dynamic determination of the Casimir pressure between two plane plates obtained using a micromachined torsional oscillator. The main improvements in the current experiment are a significant suppression of the surface roughness of the Au layers deposited on the interacting surfaces, and a decrease in the experimental error in the measurement of the absolute separation. A metrological analysis of all data permitted us to determine both the random and systematic errors, and to find the total experimental error as a function of separation at the 95% confidence level. In contrast to all previous experiments on the Casimir effect, our smallest experimental error ($\sim 0.5$%) is achieved over a wide separation range. The theoretical Casimir pressures in the experimental configuration were calculated by the use of four theoretical approaches suggested in the literature. All corrections to the Casimir force were calculated or estimated. All theoretical errors were analyzed and combined to obtain the total theoretical error at the 95% confidence level. Finally, the confidence interval for the differences between theoretical and experimental pressures was obtained as a function of separation. Our measurements are found to be consistent with two theoretical approaches utilizing the plasma model and the surface impedance over the entire measurement region. Two other approaches to the thermal Casimir force, utilizing the Drude model or a special prescription for the determination of the zero-frequency contribution to the Lifshitz formula, are excluded on the basis of our measurements at the 99% and 95% confidence levels, respectively. Finally, constraints on Yukawa-type hypothetical interactions are strengthened by up to a factor of 20 in a wide interaction range.

description: Brazil is the largest exporter and third largest producer in the chicken meat market. Consequently, it is important to know the relationship between domestic and export prices. Through the Granger causation method and the cointegrating method of Engle and Granger and the Johansen one, this study aims to verify the hypothesis of long-term relationship between both domestic and export prices of chicken meat. The results indicate that prices are cointegrated. The conclusion is that the prices received by the Brazilian producers are possibly sensible to the behavior of world market prices, and therefore they should worried about internal factors which may enlarge differences between both prices.

The series is targeted at the wide range of stakeholders involved in cotton sector reforms in West and Central Africa (WCA). This introductory brief focuses on the cotton sector structural model most prevalent in WCA —the ‘filière integrée’. The brief reviews the early successes of the ‘filière integrée’ approach and the more recent history of crisis and reforms. This sets the stage for comparisons between the ‘filière integrée’ system of WCA and other systems that are described in subsequent briefs.

The interactions of LCK in T cells and its regulation by CD45
Creators: name: Lefebvre, Dennis C.
Publisher: name: University of British Columbia
Year: 2009

description: Lck is a Src-family tyrosine kinase whose activity is essential for T cell activation and development. The phosphorylation of two key tyrosine residues in Lck, Tyr 505 and Tyr 394, regulate its activation by inducing profound changes in conformation. In vitro, CD45, a leukocyte-specific tyrosine phosphatase, preferentially dephosphorylated Tyr 394, as opposed to Tyr 505, and this specificity depended on the Lck non-catalytic domains and not the sequence specificity of the phosphatase catalytic pocket. The Lck non-catalytic domains enhanced the rate of CD45-mediated Tyr 394 dephosphorylation, and inhibited, but did not block catalysis at Tyr 505. A direct, specific, non-catalytic interaction was observed between the second phosphatase domain of CD45 (D2) and subdomain X(SD10) of Lck. This interaction was also shown to influence CD45 substrate specificity as the replacement of Erkl SD10 with that of Lck resulted in the conversion of Erkl into a more efficient CD45 substrate. In T cells, the majority of CD45 is constitutively associated with a smaller protein aptly named CD45-associated protein (CD45AP). An interaction between Lck and CD45AP was determined to occur independently of CD45 in T cells. A direct CD45AP:Lck interaction was confirmed in vitro, and was shown to antagonize the ability of CD45 to interact with Lck. Moreover, the presence of CD45AP significantly inhibited CD45-mediated Lck dephosphorylation at Tyr 394, but not Tyr 505, suggesting a role for CD45AP in sustaining Lck activity in the cell. CD44 is a widely expressed transmembrane adhesion molecule that requires the activity of Src-family kinases in T cells to induce cytoskeletal changes associated with cell adhesion. Here, Src-family kinases Lck and Fyn were both shown to associate with CD44 in T cells. In vitro, the CD44 cytoplasmic domain bound to Lck directly in a zinc dependent manner, but did not bind to Fyn. The treatment of T cells with cation chelator 1,10-phenanthroline both disrupted the CD44:Lck association and blocked CD44-induced cytoskeletal changes. This suggests that the zinc-dependent Lck association with CD44 plays a key role in mediating CD44-induced cell signaling events required for cell adhesion.

description: Using the Green Bank Telescope, we have conducted a survey for 1.3 cm water maser emission toward the nuclei of nearby active galaxies, the most sensitive large survey for H2O masers to date. Among 145 galaxies observed, maser emission was newly detected in eleven sources and confirmed in one other. Our survey targeted nearby (v < 12,000 km/s, mainly type 2 AGNs north of declination -20 degrees, and includes a few additional sources as well. We find that more than a third of Seyfert 2 galaxies have strong maser emission, though the detection rate declines beyond v about 5000 km/s due to sensitivity limits. Two of the masers discovered during this survey are found in unexpected hosts: NGC 4151 (Seyfert 1.5) and NGC 2782 (starburst). We discuss the possible relations between the large X-ray column to NGC 4151 and a possible hidden AGN in NGC 2782 to the detected masers. Four of the masers discovered here, NGC 591, NGC 4388, NGC 5728 and NGC 6323, have high-velocity lines symmetrically spaced about the systemic velocity, a likely signature of molecular gas in a nuclear accretion disk. The maser source in NGC 6323, in particular, reveals the classic spectrum of a "disk maser" represented by three distinct groups of Doppler components. Future single-dish and VLBI observations of these four galaxies could provide a measurement of the distance to each galaxy, and of the Hubble constant, independent of standard candle calibrations.

description: This Policy Brief introduces a series of synthesis papers on the relationship between cotton sector structure and performance, drawing on recent studies of cotton sectors across Africa. The series is targeted at the wide range of stakeholders involved in cotton sector reforms in West and Central Africa (WCA). This introductory brief focuses on the cotton sector structural model most prevalent in WCA—the ‘filière integrée’. The brief reviews the early successes of the ‘filière integrée’ approach and the more recent history of crisis and reforms. This sets the stage for comparisons between the ‘filière integrée’ system of WCA and other systems that are described in subsequent briefs.

description: In this paper, we discuss about the possibility to enhance the tensor-to-scalar ratio $r$ under the condition of Trans-Planckian censorship conjecture (TCC), thus $r\sim O(10^{-3})$ could be observable within the sensitivity of future experiments. We make use of the scalar-tensor theory where inflaton is nonminimally coupled to gravity. After demonstrating that the TCC condition could be modified in scalar-tensor theory, we show that due to the effects of modified gravity at the end of inflation, a large $r\sim O(10^{-3})$ could be allowed without violating the TCC. Moreover, the modification can give rise to a weak coupling of gravity to the inflation field. If such an effect has been present as early as inflation starts, it would imply that in our case, the Universe might have experienced an asymptotically safe period at its early time.

description: The measurement of the deviation of the 2-3 leptonic mixing from maximal, D_23 = 1/2 - sin^2(theta_23), is one of the key issues for understanding the origin of the neutrino masses and mixing. In the three-neutrino context we study the dependence of various observables in the atmospheric neutrinos on D_23. We perform a global three-neutrino analysis of the atmospheric and reactor neutrino data taking into account the effects of both the oscillations driven by the "solar" parameters (Delta_m_21^2 and theta_12) and the 1-3 mixing. The departure from the one-dominant mass scale approximation results into the shift of the 2-3 mixing from maximal by Delta_sin^2(theta_23) ~ 0.04, so that D_23 ~ 0.04 +- 0.07 (1 sigma). Though value of the shift is not statistically significant, the tendency is robust. The shift is induced by the excess of the e-like events in the sub-GeV sample. We show that future large scale water Cherenkov detectors can determine D_23 with accuracy of a few percent, comparable with the sensitivity of future long baseline experiments. Moreover, the atmospheric neutrinos will provide unique information on the sign of the deviation (octant of theta_23).

description: Deformations of Dubrovin's Hurwitz Frobenius manifolds are constructed. The deformations depend on $g(g+1)/2$ complex parameters where $g$ is the genus of the corresponding Riemann surface. In genus one, the flat metric of the deformed Frobenius manifold coincides with a metric associated with a one-parameter family of solutions to the Painlevé-VI equation with coefficients $(1/8,-1/8,1/8,3/8).$ Analogous deformations of the real doubles of the Hurwitz Frobenius manifolds are also found; these deformations depend on $g(g+1)/2$ real parameters.

Physical parameters of active galactic nuclei derived from properties of jet geometry transition region

description: We use the observed jet boundary transition from parabolic to conical shape, which was earlier discovered as possibly a common effect in active galactic nuclei, to estimate a black hole, a jet and an ambient medium parameters. We explained earlier the geometry transition as a consequence of a change in the jet inner properties: a transition from a magnetically dominated to an equipartition regime. This interpretation allows us to estimate a black hole spin, a black hole mass and an ambient pressure amplitude, using the observed jet shape break position and the jet width at the transition point for 11 active galactic nuclei. The black hole spin values obtained using our method are consistent with the lower estimates for the sources with redshift $z<2$ from the spin evolution modelling. We find that the method of a black hole mass determination based on the relation between the broad-line region size and its luminosity may underestimate masses of the sources with large jet viewing angles. We propose a new method for the black hole mass determination, with the obtained masses being in interval $10^8-10^{10}\;M_{\odot}$. The range of the values of the ambient pressure amplitude points to the uniform medium conditions for the sources in our sample, with a tentative indication of higher pressure around FRII sources.

A Theory of Migration as a Response to Occupational Stigma

subject: General equilibrium

description: Drawing on the literature of occupational status and social distance, a theory is developed of labor migration that is prompted by a desire to avoid “social humiliation.” A closed-economy general equilibrium model that incorporates occupational status and examines the interaction between the goods market and the labor market is constructed. This framework is then extended from a closed, single economy to an open economy setting in a world that consists of two countries or two regions. It is shown that as long as migration can reduce humiliation sufficiently, migration will occur even between two identical economies. Hence, a new model of migration is presented in which migration arises from a wish to reap social exposure gains. The model shows that migration increases the number of individuals who choose to perform degrading jobs and that consequently, migration lowers the price of the good produced in the sector that is associated with low social status. Moreover, the more migration reduces the “humiliation” of performing degrading jobs, the larger the number of individuals who end up choosing such jobs, and the lower the wage in that sector. Finally, a welfare analysis is conducted, comparing the level of wellbeing in an open economy with the level of wellbeing in a closed economy. It is shown that the greater an individual’s aversion to performing degrading jobs, the more likely it is that he will experience a welfare gain when the economy opens up.

A heuristic algorithm for automated routing in integrated circuits
Creators: name: Sepasi, Amir Hossein
Publisher: name: University of British Columbia
Year: 2009

description: In recent years artificial intelligence techniques have been extensively applied to. real world problems. Two common characteristics of the problems amenable to heuristics are: their large search space that makes exhaustive search practically impossible; and for most applications the need to find a near-optimal solution - instead of exact - in a reasonable and cost effective time frame. Most of the problems throughout the design of Very Large Scale Integration (VLSI) circuits are combinatorial, which implies a huge search space. Furthermore the sheer number of components makes exhaustive search impossible. One of the common problems in this area is routing the terminals in the layout in a reasonable amount of time. Until very recently, manual routing was the most reliable way of doing routing. As the scale of integration grows, manual routing becomes practically impossible. There has been lots of research and studies on how automated routing can successfully replace manual routing. The purpose of this thesis is a to find an automated method that helps find a good solution to this problem in a reasonable amount of time.
