description: The availability of an abundance of knowledge sources has spurred a large amount of effort in the development and enhancement of Information Retrieval techniques. Users information needs are expressed in natural language and successful retrieval is very much dependent on the effective communication of the intended purpose. Natural language queries consist of multiple linguistic features which serve to represent the intended search goal. Linguistic characteristics that cause semantic ambiguity and misinterpretation of queries as well as additional factors such as the lack of familiarity with the search environment affect the users ability to accurately represent their information needs, coined by the concept intention gap. The latter directly affects the relevance of the returned search results which may not be to the users satisfaction and therefore is a major issue impacting the effectiveness of information retrieval systems. Central to our discussion is the identification of the significant constituents that characterize the query intent and their enrichment through the addition of meaningful terms, phrases or even latent representations, either manually or automatically to capture their intended meaning. Specifically, we discuss techniques to achieve the enrichment and in particular those utilizing the information gathered from statistical processing of term dependencies within a document corpus or from external knowledge sources such as ontologies. We lay down the anatomy of a generic linguistic based query expansion framework and propose its module-based decomposition, covering topical issues from query processing, information retrieval, computational linguistics and ontology engineering. For each of the modules we review state-of-the-art solutions in the literature categorized and analyzed under the light of the techniques used.
Optimizing environmental education and awareness strategies for sustainable forest management in Kenya

description: Forests and allied environmental resources are important for environmental and socio-economic development. However, information is scarce on the ways of optimizing the strategies for forestry and environmental education and awareness in many developing countries. Using a literature review and document content analysis, this study explores the case of four forested ecosystems in Kenya with the aim of contributing to a better understanding of the strategies to achieve sustainable forest management. Results show that the key ingredients of effective forestry and environmental education are formal education infrastructure, community engagement panels, digital platforms, corporate responsibility initiatives, media, arts, policy advocacy, and research with feedback loops on initiatives. In addition, results indicate that Kenya is desirous of establishing robust mechanisms for effective environmental education and awareness, as demonstrated by policy and legal actions. Case studies of Cherangani, Mt. Kenya, Aberdares, and Kakamega forest ecosystems demonstrate these commendable efforts by embedding the ingredients of strategy optimization within their forest ecosystem management plans. However, while there is a general similarity in the approaches across the ecosystems, there is a need to optimize awareness strategies by leveraging the existing educational infrastructure, increasing stakeholder engagement, and addressing outstanding challenges currently inhibiting sustainable forest management in the examined ecosystems.

description: The economy of northwest Arkansas, including the Lincoln Lake watershed (a sub-watershed of the Illinois River), relies greatly upon livestock and poultry production. The supply of production by-products is increasingly under scrutiny as one of the potential sources of water pollution in the region. In light of the recent economic crisis, methodologies that help producers to evaluate the environmental and economic impacts of several practices before implementing them may be a cost-effective means of increasing BMP adoption. This study uses stochastic dominance techniques to evaluate, environmentally and economically, ten best management practices (BMPs) combinations to lessen water pollution in the Lincoln Lake watershed. All BMP combinations analyzed were effective in reducing total phosphorous (TP) losses. However, six combinations also decreased net returns (NR) when compared to a baseline. This suggests that including BMPs in the bermudagrass production systems may lead to increased NR risk. Without additional incentives, producers will not likely implement these BMP combinations regardless of their TP reduction benefits. Although, as expected, rankings of BMP combinations in terms of TP or NR differed from each other, four scenarios established that environmental and economic goals are not necessarily conflicting; they may be complementary. Additionally, this analysis revealed that producers’ risk preferences did not matter when selecting among the top-four BMP combinations but it could be a factor for other less preferred scenarios.

Among them there are either exotic states as the X(1600) or the recently measured charm states $D_{sJ}^*$ and X(3872) and some of the light scalar mesons. In this work we present a possible description of these states in terms of tetraquarks.

description: End-to-end encryption has become a requirement for secure messaging, which has improved a lot since Signal introduced the Double Ratcheting algorithm for end-to-end encryption. Although metadata is often needed by service providers to fulfill their tasks i.e. forward messages, it is usually not end-to-end encrypted. Another problem is that most mobile messaging apps depend on phone numbers as unique identifiers. However, it is increasingly difficult to acquire anonymous prepaid cards. Further, contact discovery often works via upload of the address book to the server, exposing sensitive data. Motivated to find a messaging service that does not have the above-mentioned drawbacks, this thesis shows how to evaluate the security and privacy of secure messaging services. For this, a case study of Wire was conducted and compared to other services i.e. Signal. The main questions answered in this thesis are (1) how can the security of the Wire protocol be evaluated, (2) how does Wire perform in trust establishment, conversation security and transport privacy compared to Signal and (3) how much metadata does Wire expose? To do this, a test setup with a self-hosted Wire server without AWS dependencies was built to inspect the Wire protocol, the REST API and the database, particularly for metadata. The Wire protocol was evaluated regarding trust establishment, conversation security and transport privacy. To help understanding the Wire protocol, a Pidgin plugin was developed which implements most features of Wire's protocol to support end-to-end encrypted messaging. Further, the production environments of Wire's and Signal's official servers were analyzed with a focus on TLS security, HTTP security headers and cookie security. To conclude, Wire has a good security level but has room for several improvements. Especially trust establishment and its usability should be advanced. Furthermore, Wire does expose a lot of metadata which should be reduced.

description: We are conducting a survey of distant clusters of galaxies (0.5 < z < 3.0) using bent, double-lobed radio sources driven by AGN as tracers. These types of radio sources are easily detected in the ~10,000 square degree VLA FIRST survey to large distances and are frequently found in clusters since interaction with a surrounding intracluster medium (ICM) can create the ram pressure necessary to bend the radio lobes. The sources can be found in a range of cluster environments, from large-scale cluster-cluster mergers, to more relaxed clusters that include sloshing of the ICM. The bending of the radio lobes enables an estimate of the flows present in the ICM. Unlike many other cluster surveys that are biased towards the most massive clusters, our clusters span a wide mass range. Our COBRA sample includes 646 radio sources, all of which have follow-up Spitzer infrared observations. In addition, we have deep optical imaging for a significant subset of the sample. Based on our multi- wavelength analysis, we confirm that approximately 200 of the targets are clusters, with most of the remainder groups. We present our survey as well as the significant detection of a subset of our clusters in the X-ray using observations with Chandra and XMM-Newton. We discuss the advances that will be made possible with Athena.

description: In operation for more than 40 years and now in all 50 states and 6 territories, the Expanded Food and Nutrition Education Program has become a cornerstone in US nutrition education. The aim of the program is to assist limited resource audiences to acquire the knowledge, skills, attitudes, and changed behavior necessary for nutritionally sound diets, and to contribute to their personal development and improvement of the overall family diet and nutritional well-being. However, very little is known about the effectiveness of this program, especially at the national level. The purpose of this research is to determine the effectiveness of money spent on the Expanded Food and Nutrition Education Program in satisfying its stated goals for adult participants. Data from all states and territories participating in the program for the years 2000-2006 are utilized in a non-linear seemingly unrelated regression framework to estimate returns to scale and related cost measures. Controlling for participant and program characteristics, the amount of money spent on the Expanded Food and Nutrition Education Program has a positive and significant impact on two of three federal outcome indices used to measure outcomes for adults. Larger-funded programs (states/territories) are relatively more cost efficient than smaller programs.

description: Plane partitions naturally appear in many problems of statistical physics and quantum field theory, for instance, in the theory of faceted crystals and of topological strings on Calabi-Yau threefolds. In this paper a connection is made between the exactly solvable model with the boson dynamical variables and a problem of enumeration of boxed plane partitions - three dimensional Young diagrams placed into a box of a finite size. The correlation functions of the boson model may be considered as the generating functionals of the Young diagrams with the fixed heights of its certain columns. The evaluation of the correlation functions is based on the Yang-Baxter algebra. The analytical answers are obtained in terms of determinants and they can also be expressed through the Schur functions.

description: We develop measures of technical and allocative efficiency of producers in marketing certified organic products. A stochastic output distance frontier and the associated revenue share equations are estimated using comprehensive U.S. data on certified organic producers. Farm-level measures of technical efficiency are calculated and factors which enhance performance are identified. Factors that systematically influence allocative efficiency are assessed. The revenue mix of organic producers is systematically inefficient as both male and female producers rely too heavily on revenue from organic markets relative to conventional outlets.

description: The six-vertex model with Domain Wall Boundary Conditions, or square ice, is considered for particular values of its parameters, corresponding to 1-, 2-, and 3-enumerations of Alternating Sign Matrices (ASMs). Using Hankel determinant representations for the partition function and the boundary correlator of homogeneous square ice, it is shown how the ordinary and refined enumerations can be derived in a very simple and straightforward way. The derivation is based on the standard relationship between Hankel determinants and orthogonal polynomials. For the particular sets of parameters corresponding to 1-, 2-, and 3-enumerations of ASMs, the Hankel determinant can be naturally related to Continuous Hahn, Meixner-Pollaczek, and Continuous Dual Hahn polynomials, respectively. This observation allows for a unified and simplified treatment of ASMs enumerations. In particular, along the lines of the proposed approach, we provide a complete solution to the long standing problem of the refined 3-enumeration of AMSs.

description: This paper presents findings on the use of HT corn and quality-adjusted herbicide use for 12 key corn producing states using a panel data set for 1986-2008. Our preliminary findings indicate an insignificant impact of HT corn on herbicide use, conditioning or accounting for HT corn with other important drivers of corn herbicide use: HT soy, corn output price, glyphoste price, nonherbicide glyponsate price, and percentage of continuous corn and low-till corn. However, we find a positive and significant impact of HT corn on herbicide use in selected states, using regional interaction terms. We use econometric techniques to avoid spurious regression results. Other preliminary runs indicated that the results hold when running the US and regional interactions on 1986-2006 and 1986-2007 data.
The unbearable search for self : a comparison between "One Man’s Bible" and "The Unbearable Lightness of Being"
Creators: name: Xie, Xiaosi
Publisher: name: University of British Columbia
Year: 2009

description: This research paper makes an overall comparison between Gao Xingjian's "One Man's Bible" and Milan Kundera's "The Unbearable Lightness of Being" in order to demonstrate that both of the works aim to examine how individuals seek their own identity and sooth themselves during times of chaos; my emphasis will be on how both protagonists gradually establish their identity through ostensibly libertine lifestyles and how both writers' representations of women are free of misogyny, and how the female characters are imbued with a strength as vigorous as the male characters. This paper begins with a biographical introduction background to these two internationally acclaimed writers and to their importance in twentieth-century literature. The similarities in their own experiences contribute to the similarities in their works, especially in "One Man's Bible" and "The Unbearable Lightness of Being". Chapter 2 discusses how the protagonists seek their identities through sexual relationships with women. Chapter 3 and 4 demonstrate how the female characters find their identities, and how Gao and Kundera see women and feminism as reflected in the novels. Chapter 5 examines the novels' philosophical ideas. I will elaborate on each writer's own literary theories exhibited in these two novels with references to their theoretical writings. Eventually, I will come to a conclusion that both "One Man's Bible" and "The Unbearable Lightness of Being" are examples of those singular pieces of art where literature and philosophy coexist, because of their detachment from any political ideology and most importantly their concern for human beings in general.

description: We present the results of a programme to search and identify the nature of unusual sources within the All-sky Wide-field Infrared Survey Explorer (WISE) that is based on a machine-learning algorithm for anomaly detection, namely one-class support vector machines (OCSVM). Designed to detect sources deviating from a training set composed of known classes, this algorithm was used to create a model for the expected data based on WISE objects with spectroscopic identifications in the Sloan Digital Sky Survey (SDSS). Subsequently, it marked as anomalous those sources whose WISE photometry was shown to be inconsistent with this model. We report the results from optical and near-infrared spectroscopy follow-up observations of a subset of 36 bright ($g_{AB}$<19.5) objects marked as 'anomalous' by the OCSVM code to verify its performance. Among the observed objects, we identified three main types of sources: i) low redshift (z~0.03-0.15) galaxies containing large amounts of hot dust (53%), including three Wolf-Rayet galaxies; ii) broad-line quasi-stellar objects (QSOs) (33%) including low-ionisation broad absorption line (LoBAL) quasars and a rare QSO with strong and narrow ultraviolet iron emission; iii) Galactic objects in dusty phases of their evolution (3%). The nature of four of these objects (11%) remains undetermined due to low signal-to-noise or featureless spectra. The current data show that the algorithm works well at detecting rare but not necessarily unknown objects among the brightest candidates. They mostly represent peculiar sub-types of otherwise well-known sources.

Para tanto, foram utilizadas as Pesquisas Nacionais por Amostra de Domicílios (PNADs) e os Censos Demográficos, de 1976 a 2005. A análise dos dados é feita a partir de estimações de funções de Regressão de Mínimos Quadrados Ordinários que permitem testar quebras estruturais que poderiam indicar mudanças na tendência referente à posição relativa do rendimento do trabalho do pequeno produtor familiar. Ao final, observa-se que a tendência de queda da posição relativa do rendimento do trabalho do pequeno produtor familiar tendeu a se acentuar após a criação do PRONAF.---------------This article has two main parts.

Cosmology under Milne's shadow

description: Based on the magnitude--redshift diagram for the sample of supernovae Ia analysed by Perlmutter et al. (1999), Davis & Lineweaver rule out the special relativistic interpretation of cosmological redshifts at a confidence level of 23 sigma. Here, we critically reassess this result. Special relativity is known to describe the dynamics of an empty universe, by means of the Milne kinematic model. Applying only special-relativistic concepts, we derive the angular diameter distance and the luminosity distance in the Milne model. In particular, in this model we do not use the underlying metric in its Robertson-Walker form, so our exposition is useful for readers without any knowledge of general relativity. We do however, explicitly use the special-relativistic Doppler formula for redshift. We apply the derived luminosity distance to the magnitude--redshift diagram for supernovae Ia of Perlmutter et al. (1999) and show that special relativity fits the data much better than that claimed by Davis & Lineweaver. Specifically, using these data alone, the Milne model is ruled out only at a 2 sigma level. Although not a viable cosmological model, in the context of current research on supernovae Ia it remains a useful reference model when comparing predictions of various cosmological models.

description: We present LOFAR observations at 150 MHz of the borderline FRI/FRII giant radio galaxy NGC 6251. This paper presents the most sensitive and highest-resolution images of NGC 6251 at these frequencies to date, revealing for the first time a low-surface-brightness extension to the northern lobe, and a possible backflow associated with the southern lobe. The integrated spectra of components of NGC 6251 are consistent with previous measurements at higher frequencies, similar to results from other LOFAR studies of nearby radio galaxies. We find the outer structures of NGC 6251 to be either at equipartition or slightly electron dominated, similar to those of FRII sources rather than FRIs; but this conclusion remains tentative because of uncertainties associated with the geometry and the extrapolation of X-ray measurements to determine the external pressure distribution on the scale of the outer lobes. We place lower limits on the ages of the extension of the northern lobe and the backflow of the southern lobe of $t \gtrsim 250$ Myr and $t \gtrsim 210$ Myr respectively. We present the first detection of polarisation at 150 MHz in NGC 6251. Taking advantage of the high Faraday resolution of LOFAR, we place an upper limit on the magnetic field in the group of $B < 0.2 (Λ_B / 10 {\rm kpc})^{-0.5} μ$G for a coherence scale of $Λ_B < 60 {\rm kpc}$ and $B < 13 μ$G for $Λ_B = 240$ kpc.

description: We describe a method by which gravitational wave observations of eccentric binary systems could be used to test General Relativity's prediction that gravitational waves are dispersionless. We present our results in terms of the graviton having a non-zero rest mass, or equivalently a non-infinite Compton wavelength. We make a rough estimate of the bounds that might be obtained following gravitational wave detections by the space-based LISA interferometer. The bounds we find are comparable to those obtainable from a method proposed by Will, and several orders of magnitude stronger than other dynamic (i.e. gravitational wave based) tests that have been proposed. The method described here has the advantage over those proposed previously of being simple to apply, as it does not require the inspiral to be in the strong field regime nor correlation with electromagnetic signals. We compare our results with those obtained from static (i.e. non-gravitational wave based) tests.

description: Mato Grosso ao longo de sua história passou de uma economia baseada na pecuária para uma economia essencialmente agrícola, destacando-se no cenário agrícola nacional e mundial pelas suas produções e exportações de soja e algodão, dentre outros bens de origem agropastoril. Este trabalho tem como propósito compreender a heterogeneidade espacial do desenvolvimento rural mato-grossense a partir do grau de desenvolvimento de cada município. Com base em dados secundários, com recorrência à análise fatorial, adaptada de Melo & Parré (2007), ajustada para Mato Grosso, constatou-se que mais da metade dos municípios (60,99%) do Estado se posicionam abaixo da média do grau de desenvolvimento encontrada (52,99), enquanto que apenas 30,99% situam-se acima dessa.---------------Mato Grosso throughout its history went from an economy based on livestock for a mainly agricultural economy, such scenery in the national agricultural and world for their production and exports of soybeans and cotton, among other goods of pasture and agricultural origin. This work is to understand the spatial heterogeneity of rural development matogrossense from the degree of development of each council. Based on secondary data, with the recurrence factor analysis, adapted Parré & Melo (2007), adjusted for Mato Grosso, it was found that more than half of the counties (60.99%) of the state is positioned below the average of degree development found (52.99), while only 30.99% would be above that.

description: We consider the gamma-ray burst of 1997 February 28 (GRB 970228) within the ElectroMagnetic Black Hole (EMBH) model. We first determine the value of the two free parameters that characterize energetically the GRB phenomenon in the EMBH model, that is to say the dyadosphere energy, $E_{dya}=5.1\times10^{52}$ ergs, and the baryonic remnant mass $M_{B}$ in units of $E_{dya}$, $B=M_{B}c^{2}/E_{dya}=3.0\times10^{-3}$. Having in this way estimated the energy emitted during the beam-target phase, we evaluate the role of the InterStellar Medium (ISM) number density (n$_{ISM}$) and of the ratio ${\cal R}$ between the effective emitting area and the total surface area of the GRB source, in reproducing the observed profiles of the GRB 970228 prompt emission and X-ray (2-10 keV energy band) afterglow. The importance of the ISM distribution three-dimensional treatment around the central black hole is also stressed in this analysis.

description: A teoria Geral dos Sistemas (Bertalanffy, 1968) e a Teoria dos Sistemas Sociais (Loomis, 1960) podem ser usadas para explicar as relações à nível das comunidades tradicionais na Amazônia entre as ciências sociais e as ciências naturais ou as relações do homem com a natureza, inclusive como decisões tomadas envolvem o uso de tecnologia para explorar os recursos naturais. O presente trabalho aclara essa relação e oferece as dimensões e variáveis que podem ser usadas em verificação empíricas, tanto à luz da Ecologia Complexa (Morin, 1980) como da Sociologia Complexa (Alexander, 1998).----------------The General Theory of Sistems (Bertalanffy, 1968) and the The Social Systems Theory (Loomis, 1960) are used to explain the relationship between social sciences and natural sciences or the relationship between Man and nature. Both Theories also can be used to explain how traditional community in the Amazon region, ”make and take” decision on technology to be utilized in the surrounding natural resoures. The paper discuss, also social and natural dimensions and variables that can be used analyse at empirical ground such relations.

description: Operation speed and coherence time are two core measures for the viability of a qubit. Strong spin-orbit interaction (SOI) and relatively weak hyperfine interaction make holes in germanium (Ge) intriguing candidates for spin qubits with rapid, all-electrical coherent control. Here we report ultrafast single-spin manipulation in a hole-based double quantum dot in a germanium hut wire (GHW). Mediated by the strong SOI, a Rabi frequency exceeding 540 MHz is observed at a magnetic field of 100 mT, setting a record for ultrafast spin qubit control in semiconductor systems. We demonstrate that the strong SOI of heavy holes (HHs) in our GHW, characterized by a very short spin-orbit length of 1.5 nm, enables the rapid gate operations we accomplish. Our results demonstrate the potential of ultrafast coherent control of hole spin qubits to meet the requirement of DiVincenzo's criteria for a scalable quantum information processor.

Dust and star formation in the centre of NGC 3311

description: NGC 3311 is the central galaxy of the Hydra I galaxy cluster. It has a hot interstellar medium and hosts a central dust lane with emission lines. These dust lanes are frequent in elliptical galaxies, but the case of NGC 3311 might be particularly interesting for problems of dust lifetime and the role of cool gas in the central parts. We aim to use archival HST images and MUSE data to investigate the central dust structure of NGC 3311. We used the tool PyParadise to model the stellar population and extract the emission lines. The HST/ACS colour map reveals the known dust structures, but also blue spots, which are places of strong line emission. A dusty 'mini-jet' emanates from the centre. The distribution of the emission line gas matches the dust silhouette almost exactly. Close to the brightest Halpha emission, the ratio [NII]/Halpha resembles that of HII-regions; in the outer parts, [NII] gets stronger and is similar to LINER-like spectra. The gas kinematics is consistent with that of a rotating disc. The Doppler shifts of the strongest line emissions, which indicate the areas of highest star formation activity, smoothly fit into the disc symmetry. The metallicity is supersolar. The presence of neutral gas is indicated by the fit residuals of the stellar NaI D absorption line, which we interpret as interstellar absorption. We estimate the mass of the neutral gas to be of the order of the X-ray mass. The dynamical mass infers a stellar population of intermediate age, whose globular clusters have already been identified. Our findings can be harmonised in a scenario in which the star formation is triggered by the accretion of cold gas onto a pre-existing gas/dust disc or ring. Newly produced dust then contributes to the longevity of the dust.

description: In this paper we describe a theory of (branched) crystals which is adapted to the study of representations in the BGG category $\cal O$ and which generalizes the theory of normal crystals of Kashiwara. In the case of $sl_2$ we show that one can associate (uniquely up to isomorphism) to every module in $\cal O$ a branched crystal . We show that the indecomposable modules in \cal O$ correspond to "indecomposable" branched crystals. We also define the tensor product of these crystals and show that for $sl_2$ the indecomposable components of the tensor product of branched crystals are the same as the crystals associated to the indecomposable summands of the tensor product of the corresponding modules.

description: A questão da constituição de uma estratégia adequada para a promoção da inovação constitui um dos elementos-chave para os atores sociais comprometidos com os processos de transição agroecológica. Embora do ponto de vista propositivo encontrem-se referências relativamente consolidadas, há pouco conhecimento sobre a configuração que assume o sistema de informação e conhecimento local que sustenta a transição agroecológica em experiências concretas. Nesse sentido, o presente trabalho propõe-se a investigar esta problemática no âmbito de atuação da Associação de Agricultores Ecologistas de Ipê e Antônio Prado (AECIA), no RS, recorrendo a consulta à documentos e outros estudos, observação participante e entrevistas à agentes de ongs e agricultores. Os resultados apontam que a introdução da agricultura ecológica interfere na esfera das relações sociais, mais especificamente, no arranjo social da produção, fazendo emergir uma configuração nova e originando espaços sociotécnicos específicos para atender as necessidades desses atores, uma vez que o “modelo” da agricultura convencional e os atores que o sustentam, não consegue dar conta das novas demandas.------------------The matter of constitution of an adequate strategy for the promotion of innovation constitutes one of the key-elements for the social actors committed with the agro-ecological transition processes. Although in the purposive point of view there are found relatively consolidated references, there is little understanding about the configuration that assumes the information system and local knowledge that supports the agro-ecological transition in real experiences. In this way, the present work proposes itself to investigate this problem in the scope of the acting of the Ipê and Antônio Prado Ecologist Agriculturists Association (AECIA), in RS, resorting to a consultation of documents and other studies, participant observation and interviews with ONG agents and agriculturists. The results show that the introduction of the ecological agriculture interferes in the sphere of social relations, more specifically, in the social arrangement of the production, doing to emerge a new configuration and originating specific socio-technical spaces for serving the necessities of these actors, since the “model” of conventional agriculture and the actors who support it, are not able to the new demands.
