description: We give in this paper a new construction of factors of type ${\rm III_1}$. Under certain assumptions, we can, thanks to a result by Popa, give a complete classification for this family of factors. Although these factors are never full, we can nevertheless, in many cases, compute Connes' $τ$ invariant. We obtain a new example of an uncountable family of pairwise non-isomorphic factors of type ${\rm III_1}$ with the same $τ$ invariant.

description: This paper presents an estimate of the price elasticity of supply for tobacco output in Zimbabwe using an adapted Nerlovian model. The results indicate a short-run elasticity of +0.34 and a long-run elasticity of +0.81, suggesting that tobacco farmers are highly unresponsive to price changes. These estimates are similar to those obtained for tobacco in supply response studies conducted in other developing African countries.

description: The description of realistic strongly correlated systems has recently advanced through the combination of density functional theory in the local density approximation (LDA) and dynamical mean field theory (DMFT). This LDA+DMFT method is able to treat both strongly correlated insulators and metals. Several interfaces between LDA and DMFT have been used, such as (N-th order) Linear Muffin Tin Orbitals or Maximally localized Wannier Functions. Such schemes are however either complex in use or additional simplifications are often performed (i.e., the atomic sphere approximation). We present an alternative implementation of LDA+DMFT, which keeps the precision of the Wannier implementation, but which is lighter. It relies on the projection of localized orbitals onto a restricted set of Kohn-Sham states to define the correlated subspace. The method is implemented within the Projector Augmented Wave (PAW) and within the Mixed Basis Pseudopotential (MBPP) frameworks. This opens the way to electronic structure calculations within LDA+DMFT for more complex structures with the precision of an all-electron method. We present an application to two correlated systems, namely SrVO3 and beta-NiS (a charge-transfer material), including ligand states in the basis-set. The results are compared to calculations done with Maximally Localized Wannier functions, and the physical features appearing in the orbitally resolved spectral functions are discussed.

description: This contribution introduces the GTOPX space mission benchmark collection, which is an extension of GTOP database published by the European Space Agency (ESA). GTOPX consists of ten individual benchmark instances representing real-world interplanetary space trajectory design problems. In regard to the original GTOP collection, GTOPX includes three new problem instances featuring mixed-integer and multi-objective properties. GTOPX enables a simplified user handling, unified benchmark function call and some minor bug corrections to the original GTOP implementation. Furthermore, GTOPX is linked from it's original C++ source code to Python and Matlab based on dynamic link libraries, assuring computationally fast and accurate reproduction of the benchmark results in all three programming languages. Space mission trajectory design problems as those represented in GTOPX are known to be highly non-linear and difficult to solve. The GTOPX collection, therefore, aims particularly at researchers wishing to put advanced (meta)heuristic and hybrid optimization algorithms to the test. The goal of this paper is to provide researchers with a manual and reference to the newly available GTOPX benchmark software.

description: This paper uses one of four possible areas of strategic market research, namely Trademaps , to analyse the South African market potential for deciduous fruit. It isolates the apple industry to illustrate the application of Trademaps. An overview of the export performance within the apple industry is given. Export Trademaps are then utilised to analyse the trade flows and the market potential of South African apples on the world market. The Trademaps generated are based on trade data for the years 1995 to 1999 as reported by nearly 100 trading nations in the COMTRADE database of the United Nations Statistical Division. Possible strategies and options are suggested, given the results of the Trademap analysis. It is concluded that this analysis demonstrates the usefulness of Trademaps as a research tool to provide market information on new and existing markets.

The x-ray diffraction refinement suggests the superconductor crystallizes into a 0201 structure with space group I4/mmm and lattice parameters being a=3.92A, c=15.6 A. The magnetic susceptibility as well as resistance measurements indicated that the bulk superconductivity with transition temperature 30K was achieved in the sample.

Subjects: Resource /Energy Economics and Policy

description: In South Africa, the 1998 National Water Act has created two user-driven water resource management organisations, namely the Water User Association at the local level and the Catchment Management Agency at a larger catchment level. The paper investigates some challenges concerning the participation of smallholders in water resource management organisations involving also large-scale users. Specifically, the paper analyses the possible discrepancies between the needs of smallholders with regard to water and the functions of these organisations. A simple typology of needs concerning water is presented and used to classify the main problems faced by smallholders in selected case studies. In some of the cases studied, smallholders need above all funds for investment in waterworks and their operation. They are not directly affected by water resource management issue, a lack of overlap between their needs and the functions of a water resource management organisation might lead to their unsustainable presence within the organisation. In such cases, one alternative is to achieve cross-subsidization. The National Water Act calls for it, without providing specific requirement. The proposed creation of small-scale user forums in the Olifants Water Management area can be described as cross-subsidization. It might improve the internal organisation among smallholders and give them a voice. Some funds will be dedicated to forums activities, but they are not entrenched as part of the core functions of the Catchment Management Agency. This analysis shows the importance of undertaking an assessment of smallholder water related needs to orientate the public participation process.

description: Abstract

Introduction- Inflammatory bowel diseases (IBDs) includes ulcerative colitis (UC) and crohn’s disease (CD). Both are chronic recurring conditions affecting gastrointestinal tract, differing in disease course, complication and management. Accurate histopathological assessment is needed, first to distinguish IBDs from non-IBDs colitis and secondly in case of IBDs to discern between ulcerative colitis and Crohn’s disease. Aims and objectives - The aim of this study is to display the histomorphological spectrum of changes observed in endoscopic biopsy specimens performed on patient with history suggestive of colitis, thereby highlighting the pertinent changes that can lead to reliable recognition of IBD from non IBD colitis and further sub classify IBDs as UC and CD. Material and methods – 30 endoscopic biopsies performed in patients suspected of IBDs for a period of 1 year were taken into account.  Histomorphological changes noted were-1) Architectural abnormalities – surface ulceration, crypt distortion and crypt atrophy 2) Inflammation – lymphoplasmacytic / neutrophilic, cryptitis, crypt abscess, granuloma  3) Epithelial changes- mucin depletion. Initial diagnosis of IBD versus non IBD colitis was made. In cases likely to be of IBD further division into ulcerative colitis and Crohn’s disease was attempted. Result – Out of 30 cases, 60% were IBD and 40% were categorised as non-IBD. In IBD category, 83%  were subcategorised as UC, 6% as Crohn’s and 11% could not be further subcategorised. Almost all IBD cases (77%) showed architectural abnormalities and 60% mucin depletion. Conclusion- Combination of architectural and epithelial changes with accompanying inflammation patterns can prove to be effective diagnostic parameters for diagnosing endoscopic biopsies in colitis patients.

description: This study identifies different dimensions of poverty affecting the current and future well-being of households within a community of land reform beneficiaries in the Midlands of KwaZulu-Natal. A census survey of the beneficiary households was conducted in May 2002 to gather data on poverty indicators. Principal Component Analysis was used to construct an index of the standard of housing, which was then combined with variables measuring other symptoms of poverty (income, wealth and health) in a Cluster Analysis of the households. The analysis revealed five clusters representing four distinct groups of poverty; households relatively income and asset rich, households relatively income rich but asset poor, households relatively asset rich but income poor and households with the lowest incomes and assets. While income is an important indicator of current poverty, household wealth (measured in terms of saleable assets) indicates ability to cope with adverse shocks a key issue as life expectancy is declining and old-age pensioners account for a large share of household income in the survey group. It is concluded that child welfare grants could be increased as pension earnings become less effective in combating the symptoms of poverty in this area. In addition, land reform grants may address poverty more effectively when used to purchase equity in joint ventures with commercial farmers than when used to purchase land that many of the beneficiaries cannot use or transact.

description: The time evolution of local operators in quantum compass models is characterized by simplicity as it can be represented as expanding and contracting strings of operators. Here we present an analytical solution to the problem of growth of a local energy operator in a quantum compass model on a Bethe lattice. We find a linear increase in time of the average operator length and a diffusive spreading of the operator length distribution. By a moment method we evaluate the local energy autocorrelation function that shows a Lorentzian shape at low frequencies. Furthermore, by a stochastic method we visualize the expansion of the string cloud.

description: A bioeconomic model of reservoir aquaculture in northern Vietnam is used to investigate the impacts of price and yield risk on the level, variability and skewness of expected net revenue and utility. Prices and yields are assumed to follow lognormal and beta distributions, respectively. Net revenue follows a generalized gamma distribution and is found to be very risky compared with similar enterprises elsewhere, mainly due to the relatively high yield risk. This represents the nascent nature of the industry in Vietnam and the opportunity for efficiency improvements. Increasing production capacity (through increasing reservoir size, stocking density, production cycle length and harvest rate) are found to increase profits and decrease the variability of profits. Species diversification was found to reduce the riskiness of the enterprise.

description: Given a stream of entries in a multi-aspect data setting i.e., entries having multiple dimensions, how can we detect anomalous activities in an unsupervised manner? For example, in the intrusion detection setting, existing work seeks to detect anomalous events or edges in dynamic graph streams, but this does not allow us to take into account additional attributes of each entry. Our work aims to define a streaming multi-aspect data anomaly detection framework, termed MSTREAM which can detect unusual group anomalies as they occur, in a dynamic manner. MSTREAM has the following properties: (a) it detects anomalies in multi-aspect data including both categorical and numeric attributes; (b) it is online, thus processing each record in constant time and constant memory; (c) it can capture the correlation between multiple aspects of the data. MSTREAM is evaluated over the KDDCUP99, CICIDS-DoS, UNSW-NB 15 and CICIDS-DDoS datasets, and outperforms state-of-the-art baselines.

description: We take advantage of the correspondence between pseudogroups and inverse quantal frames, and of the recent description of Morita equivalence for inverse quantal frames in terms of biprincipal bisheaves, to define Morita equivalence for pseudogroups and to investigate its applications. In particular, two pseudogroups are Morita equivalent if and only if their corresponding localic étale groupoids are. We explore the clear analogies between our definition of Morita equivalence for pseudogroups and the usual notion of strong Morita equivalence for $C^{\ast}$-algebras and these lead to a number of concrete results.

description: Eating quality is one of the most important factors influencing demand for beef. Meat Standards Australia is a voluntary beef grading system aimed at improving consumer certainty about beef quality, improving overall beef quality and strengthening supply chain linkages. Since its inception in 1999/2000, substantial improvements in beef quality, as measured by the system, have been identified. An evaluation was undertaken to estimate the economic value of these improvements to the industry. It was found that MSA graded beef consistently attracted premiums above nongraded beef, with mean values of 29c/kg and 39c/kg (carcass equivalent) at the wholesale and retail levels respectively, while the food service sector received an average of 39c/kg (carcass equivalent). The total retail value of the program to date is estimated to be between $218 to 230 million and $171 million at the wholesale level (in terms of 2005 prices).

description: The willingness to pay (WTP)/willingness to accept (WTA) disparity raises serious questions about preference elicitation techniques based on the Hicksian model of decision-making. In this paper we investigate the possibility of incorporating the strategies suggested by Plott and Zeiler (2005) in a Pivot Process mechanism and in a Choice Modelling experiment to eliminate the WTP/WTA disparity. The goal is to improve the reliability of the benefit estimates by comparing and contrasting these two methodologies. No methodological and analytical obstacles prevent the use the Pivot Process to calibrate the Choice Modelling estimates. By combining the two methods, a calibration procedure can be usefully developed to validate good hypothetical surveys and correct bad ones.

description: Temperature sensing is a ubiquitous cell behavior, but the fundamental limits to the precision of temperature sensing are poorly understood. Unlike in chemical concentration sensing, the precision of temperature sensing is not limited by extrinsic fluctuations in the temperature field itself. Instead, we find that precision is limited by the intrinsic copy number, turnover, and binding kinetics of temperature-sensitive proteins. Developing a model based on the canonical TlpA protein, we find that a cell can estimate temperature to within 2%. We compare this prediction with in vivo data on temperature sensing in bacteria.

description: This paper reports on an analysis of technical efficiency and varietal differences in pistachio production in Iran. A random sample of 475 farmers was selected from the province of Kerman in 2003 and 2004. In this study, farmers are classified into three groups according to the variety of tree they planted. The three main varieties of pistachio trees planted are Kalleh- Ghuchi, Fandoghi and Akbari. The technical efficiency indices are computed using three approaches. First, a standard stochastic production frontier was employed using pooled data. Secondly, stochastic frontier production functions were estimated for each variety (separately). Lastly, the meta-frontier approach was used because production varieties and technologies are expected to differ between the three varieties. Use of this method enabled technical efficiency scores to be corrected by the coefficient of the variety-technology gap ratio (VTGR). Estimates of the frontier were obtained assuming a translog functional form. Results indicate that the mean values of technical efficiency in 2003 and 2004 for the pooled frontier, variety group frontiers and meta-frontier across all data are 54 per cent, 55 per cent and 62 per cent, respectively. The mean value of VTGR in 2003 and 2004 varies from 0.58 for the Kalleh-Ghuchi variety to 0.68 for the Fandoghi variety. These results show the importance of taking into account the differences in frontiers imposed by different tree varieties.
Salmonella Typhimurium genes induced upon bacterial invasion into mammalian cells
Creators: name: Pfeifer, Cheryl Gurine
Publisher: name: University of British Columbia
Year: 2009

description: In causing gastroenteritis, Salmonella typhimurium are able to invade and grow within non-phagocytic intestinal cells. They are also able to survive within phagocytic cells, and have the potential to cause systemic disease. The ability of these bacteria to be intracellular is important in the disease process. Salmonella express an unique set of genes inside macrophages (not expressed with other stresses, e.g. heat, low pH, starvation), however, only a few have been identified. Therefore, the goal of this study was to search for Salmonella genes only expressed inside cells, thereby identifying genes essential for intracellular survival and perhaps virulence. A light-based reporter system was developed to specifically detect gene expression from intra-cellular bacteria. Vibrio harveyi luciferase genes, luxAB, were fused to Salmonella plasmid virulence genes, spvRAB, and the construct was shown to be upregulated after Salmonella invasion into epithelial cells. Upregulation was also demonstrated using a similar B-galactosidase (lacZ) reporter gene fusion. The results indicated luciferase was a sensitive reporter, able to monitor bacterial gene expression from within host cells, and able to differentiate live from dead bacteria. Subsequently, a library of S. typhimurium mutants was made by randomly inserting promoterless luxAB genes into the bacterial chromosome. Individual mutants were screened for luciferase expression (i.e. light production) within phagocytic cells. Extracellular bacterial mutants expressing light during growth in rich media or in the presence of cell-secreted factors were eliminated. From this screen, four S. typhimurium genes were identified as upregulated within both phagocytic and non-phagocytic cells. Three genes were found located within "Salmonella pathogenicity islands" (SPI): sigD/sopB and pipBwithin SPI-5 and ssaR within SPI-2. The sigD/sopB gene encodes an inositol phosphate phosphatase affecting host cell signalling pathways and chloride secretion. The ssaR gene potentially encodes a type III secretion apparatus component. Bacterial type III secretion systems are highly regulated and specialized for secretion of bacterial proteins directly into host cells. The fourth gene (iicA for induced mtracellularly) was completely novel. The four bacterial mutants retained their ability to invade and grow within cultures cells, and all but iicA were requiredfor virulence in a mouse model. This work confirms Salmonella pathogenicity includes genes expressed in the intracellular environment. The ability to identify such genes, and their further characterization has led to an enhanced understanding about how Salmonella functions as an intracellular pathogen, in addition to identifying specific virulence factors.

description: Often sensitive industries such as those dependent on agricultural resources are left out of FTAs. On the other hand, FTAs can bring in specific non-WTO aspects like competition policy to facilitate trade. In this paper, the development of the AANZFTA is analysed within a framework characterising "good" FTAs, and in terms what it may deliver with respect to resource-based industries. Past FTAs involving partner countries, changes over time, interviews with and submissions from relevant parties are analysed. The analysis suggests that the AANZFTA will be a more difficult agreement to develop to fruition than have bilateral agreements between the parties.

Due to unfavourable climatic conditions in collection rooms of the Natur-Museum Lucerne, mould developed on objects from all areas of the collection or on their storage containers. Since some principles have to be taken into account in the remediation of mould infestation, a concept for the professional containment and remediation of the mould was developed together with external experts. The various steps from immediate measures to careful evacuation to cleaning are presented in this article.

description: A scenario is proposed in which the matter-antimatter asymmetry behaves like a seed for the inflationary phase of the universe. The mechanism which makes this scenario plausible is the holographic principle: this scheme is supported by a good prediction of the number of e-folds. It seems that such a mechanism can only work in the presence of a Hagedorn-like phase transition. The issue of the "graceful exit" can also be naturally accounted for.

description: Natural resource management decision making by Catchment Management Authorities in NSW is being aided by a project involving bio-physical modelling and the development of an alternative decision-making framework. The objective of the bio-physical modelling process is to generate predictions of environmental or natural resource outcomes rather than project outputs. These outcomes can then be used in an investment framework to help priority setting and project decision making. Questions that arise in bio-physical modelling include those relating to scale and scope. Scale issues include how to address the landscape impacts of particular (or a series of local) on-ground works proposals. Scope issues include assessment of multiple-attribute responses to particular changes. In a multi-disciplinary context the challenge is then to translate this information into units that can be adapted to a decision-support framework. Existing Catchment Management Authorities decisions are often based on scoring and weighting of environmental improvements using an environmental benefits index, however other economic frameworks are possible. We discuss the important context for these questions in the decision making framework.

Genetically-engineered populus hybrids and metalliferous soil remediation
Creators: name: Schmidt, Monica A.
Publisher: name: University of British Columbia
Year: 2009

description: With global heavy metal pollution increasing, there is a need for innovative metal decontamination processes. Plants that have the ability to sequester metal contaminants within their tissues promise to be a cost-effective soil remediation practice. A poplar hybrid clone, Populus alba x P.tremula (INRA clone 717-1B4), was selected for this soil metal remediation research due to its large biomass and extensive deep tap root system that enables it to encounter many contaminants within its surroundings. The response of poplar to heavy metal stress, primarily cadmium and copper, was studied at the molecular level as a means to assess its metal stress-induced defense mechanisms. Metal toxicity tests and chemical inhibition studies to limit the formation of phytochelatins indicate that this metal-chelating compound plays a role in conferring tolerance to both Cd and Cu stress. Metallothioneins were seen to be constitutively expressed in all tissue regardless of metal stress conditions. Conversely, the production of phytochelatins, as monitored by the expression of the glutathione synthetase gene, was seen to be strongly induced by both Cd and Cu-stress in leaf and stem tissue and weakly induced in root tissue. Genetically-engineered poplar hybrids, that express the fission yeast Schizosaccharomyces pombe vacuole transporter gene, HMT, were produced. After exposure to cadmium stress, it was found that the transformants analyzed did not exhibit an enhanced level of metal tolerance nor did they accumulate elevated levels of metal ions within their tissues. It was hypothesized that in order for this particular poplar hybrid to be engineered to have the metalaccumulating phenotype that both the HMT vacuole membrane transporter and the up-regulation of phytochelatins in roots would be needed.
Electron interference in mesoscopic devices in the presence of nonclassical electromagnetic fields

description: The interaction of mesoscopic interference devices with nonclassical electromagnetic fields is studied. The external quantum fields induce a phase factor on the electric charges. This phase factor, which is a generalization of the standard Aharonov-Bohm phase factor, is in the case of nonclassical electromagnetic fields a quantum mechanical operator. Its expectation value depends on the density matrix describing the nonclassical photons and determines the interference. Several examples are discussed, which show that the quantum noise of the nonclassical photons destroys slightly the electron interference fringes. An interesting application arises in the context of distant electron interference devices, irradiated with entangled photons. In this case the interfering electrons in the two devices become entangled. The same ideas are applied in the context of SQUID rings irradiated with nonclassical electromagnetic fields. It is shown that the statistics of the Cooper pairs tunneling through the Josephson junction depend on the statistics of the photons.

description: New Zealand's biodiversity consists of over 80,000 types of native plants, animals and fungi, a considerable number of which are indigenous and located on private property. To preserve and enhance native biodiversity and discourage activities that may deplete it, economic values can be calculated which can, in turn, guide the use of policy tools, such as incentives, that can be used. This can support behavioural changes by encouraging individual self-interest to coincide with social interest. In this project, we used the contingent valuation, choice modelling and well-being approaches to estimate native biodiversity values for Wellington residents. In this paper, we present a summary of our initial results.

description: Consider the wave equation with constant or variable coefficients in $\R^3$. The initial datum is a random function with a finite mean density of energy that also satisfies a Rosenblatt- or Ibragimov-Linnik-type mixing condition. The random function converges to different space-homogeneous processes as $x_3\to\pm\infty$, with the distributions $μ_\pm$. We study the distribution $μ_t$ of the random solution at a time $t\in\R$. The main result is the convergence of $μ_t$ to a Gaussian translation-invariant measure as $t\to\infty$ that means central limit theorem for the wave equation. The proof is based on the Bernstein `room-corridor' argument. The application to the case of the Gibbs measures $μ_\pm=g_\pm$ with two different temperatures $T_{\pm}$ is given. Limiting mean energy current density formally is $-\infty\cdot (0,0,T_+ -T_-)$ for the Gibbs measures, and it is finite and equals to $-C(0,0,T_+ -T_-)$ with $C>0$ for the convolution with a nontrivial test function.

description: Watershed degradation is a major environmental concern in the steeply sloping uplands of the Philippines. Land use in these upland regions is dynamic and there is growing interest in how livelihood strategies bring about land-use change in the uplands, with impacts on other resource users elsewhere in the watershed. The Landcare Program has helped develop conservation farming practices that both mitigate against the degradation process and have a positive impact on farm livelihoods. This paper explores the dynamics of landuse change in upland watersheds in Bohol Province as a basis for evaluating the economic impacts of the Landcare Program.
