description: O artigo analisa estratégias adotadas por setores do agronegócio no campo das ações de responsabilidade social para erradicar a exploração do trabalho infantil no Brasil. No contexto da globalização da economia e da internacionalização dos direitos da infância, setores empresariais de cadeias produtivas do agronegócio passaram a desenvolver ações de responsabilidade social para combater o trabalho infantil, mediante a adesão aos selos sociais, assinatura de pactos e proposição de projetos sociais. As empresas vinculadas ao agronegócio aderiram a projetos de responsabilidade social empresarial em virtude da inclusão de cláusulas sociais nos mercados internacionais, da intensificação da fiscalização do poder público, bem como do compromisso na construção do desenvolvimento sustentável.------------------------------The article examines strategies adopted by sectors of the agribusiness in the stock of social responsibility to eradicate the exploitation of child labor in Brazil. In the context of economic globalisation and internationalisation of the rights of children, business sectors of the agribusiness production chains began to develop actions of social responsibility to combat child labour through adherence to the social stamps, signing of agreements and proposals for social projects. Companies linked to agribusiness joined the projects for corporate social responsibility because of the inclusion of social clauses in international markets, the strengthening of supervision of public power, and the commitment in the construction of sustainable development.
Spoken word recognition by children with and without specific language impairment : an examination of lexical characteristics
Creators: name: Lewis, Julie A.
Publisher: name: University of British Columbia
Year: 2009

description: The current study had three aims: 1) To examine spoken word recognition by children with and without specific language impairment (SLI), 2) To investigate the effects of two lexical characteristics, age of acquisition and neighbourhood density, on spoken word recognition, and 3) To explore possible links between spoken word recognition and phonological short-term memory or semantic knowledge. Eight school-aged children with SLI and nine typically developing children matched for comprehension vocabulary completed three experimental tasks. First, they listened to 28 common nouns presented in a gating paradigm. The 28 words varied along the dimensions of age of acquisition (early- versus late-acquired) and neighbourhood density (words from sparse versus dense phonological neighbourhoods) so that there were four types of words: early/sparse, early/dense, late/sparse and late/dense. Participants were asked to identify the word being presented. Second, participants completed a word-picture matching task (from a choice of four pictures) that measured the depth of their semantic knowledge of the same 28 words. Third, children repeated nonsense words that varied from one to four syllables in length as a measure of their phonological short-term memory. Results from the gating task found no significant difference between groups. For both groups, children recognized early-acquired words from sparse neighbourhoods more quickly than early-acquired words from dense neighbourhoods and late-acquired words from both sparse and dense neighbourhoods. A significant correlation was found between the gating task and the nonsense word repetition task for all participants. The longer the phonological short-term memory span, the more quickly words were recognized for all children. A strong and marginally significant correlation was found between the gating task and the word-picture matching task for the children with SLI only: the higher the number of words they could correctly match to a picture the more quickly words were recognized in the gating task. These results suggest that children with SLI do not have a deficit relative to vocabulary-matched peers in the recognition of single, spoken, words. Furthermore, the current findings provide some degree of support for a relationship between spoken word recognition and both phonological short-term memory and depth of semantic knowledge.

Modelling the spin equilibrium of neutron stars in LMXBs without gravitational radiation

description: In this paper we discuss the spin-equilibrium of accreting neutron stars in LMXBs. We demonstrate that, when combined with a naive spin-up torque, the observed data leads to inferred magnetic fields which are at variance with those of galactic millisecond radiopulsars. This indicates the need for either additional spin-down torques (eg. gravitational radiation) or an improved accretion model. We show that a simple consistent accretion model can be arrived at by accounting for radiation pressure in rapidly accreting systems (above a few percent of the Eddington accretion rate). In our model the inner disk region is thick and significantly sub-Keplerian, and the estimated equilibrium periods are such that the LMXB neutron stars have properties that accord well with the galactic millisecond radiopulsar sample. The implications for future gravitational-wave observations are also discussed briefly.

Phase Referencing and Narrow-Angle Astrometry in Current and Future Interferometers

description: Atmospheric turbulence is a serious problem for ground-based interferometers. It places tight limits on both sensitivity and measurement precision. Phase referencing is a method to overcome these limitations via the use of a bright reference star. The Palomar Testbed Interferometer was designed to use phase referencing and so can provide a pair of phase-stabilized starlight beams to a second (science) beam combiner. We have used this capability for several interesting studies, including very narrow angle astrometry. For close (1-arcsecond) pairs of stars we are able to achieve a differential astrometric precision in the range 20-30 micro-arcseconds.

description: We report on a statistical study of prominence eruptions (PEs) using a catalog of these events routinely imaged by the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO) in the 304 Å pass band. Using an algorithm developed as part of an LWS project, we have detected PEs in 304 Å synoptic images with 2-min cadence since May 2010. A catalog of these PEs is made available online (https://cdaw.gsfc.nasa.gov/CME_list/autope/). The 304 Å images are polar-transformed and divided by a background map (pixels with minimum intensity during one day) to get the ratio maps above the limb. The prominence regions are defined as pixels with a ratio $\ge$2. Two prominence regions with more than 50% of pixels overlapping are considered the same prominence. If the height of a prominence increases monotonically in 5 successive images, it is considered eruptive. All the PEs seen above the limb are detected by the routine, but only PEs with width $\ge$15° are included in the catalog to eliminate polar jets and other small-scale mass motions. The identifications are also cross-checked with the PEs identified in Nobeyama Radioheliograph images (http://solar.nro.nao.ac.jp/norh/html/prominence/). The catalog gives the date, time, central position angle, latitude, and width of the eruptive prominence. The catalog also provides links to JavaScript movies that combine SDO/AIA images with GOES soft X-ray data to identify the associated flares, and with SOHO/LASCO C2 images to identify the associated coronal mass ejections. We examined the statistical properties of the PEs and found that the high-latitude PE speed decreased with the decreasing of the average polar magnetic field strength of the previous cycle.

description: This study is primarily concerned with the planning and management of a multipurpose reservoir. An economic optimization model using non-linear programming is developed and solved using Risk Solver to maximize the net economic benefits derived from different use of reservoir water under uncertainties. Marketed: urban and rural water supply and hydropower generation and non-marketed: lake recreation uses are considered directly in the maximization problem while flood control and downstream releases are incorporated as constraints. Stochastic inflows to the reservoir are considered to be log normally distributed. Lake Tenkiller because of its clear water and scenic beauty is chosen for this study. A mass balance equation is used to determine the level and volume of water in the lake for each period over the year 2010. Both the value of a visitor day and the number of visitor are the function of lake level which makes it completely unique. Results show that for Lake Tenkiller it is beneficial to maintain the lake level at around 634 feet above mean sea level (famsl) until mid-August, and then start drawing down for hydropower generation. A sensitive analysis is also performed with different values of visitor day and peak electricity prices. However, the results remain the same for all different scenarios making the model completely robust and the solution also satisfies the equi-marginal principle.

description: Evaluating the impact on market performance of investments in agricultural market information systems (MIS) face several methodological challenges. These fall into two broad categories: (a) defining the dimensions of market performance to measure (which is a function of whom the MIS is designed to serve) and identifying reliable indicators of those performance dimensions, and (b) identifying the causal effects of the MIS. The determination of causal effects in turn requires establishing a credible baseline, measuring “treatment effects” (i.e., the effects on economic behavior of receiving improved information from an MIS), dealing with problems of endogenous placement of treatment, and interpreting the validity of stakeholders’ statements and governments’ revealed preferences regarding the utility of MIS. Many of these challenges arise because improved market information can affect the welfare of market actors through improved market polices and increased competition even if those actors do not have direct access to that information. The paper discusses these challenges and identifies approaches that may be useful in developing a “convergence of evidence” concerning whether investment in a given MIS is socially worthwhile.

description: Spatial light modulators can typically only modulate the phase or the amplitude of an incident wavefront, with only a limited number of discrete values available. This is often accounted for in computer-generated holography algorithms by setting hologram pixel values to the nearest achievable value during what is known as quantisation. Sympathetic quantisation is an alternative to this nearest-neighbour approach that takes into account the underlying diffraction relationships in order to obtain a significantly improved post-quantisation performance. The concept of sympathetic quantisation is introduced in this paper and a simple implementation, soft sympathetic quantisation, is presented which is shown to improve mean squared error and structural similarity index error metrics by 50% for the considered case of single-transform algorithms.
Decay of Affleck-Dine Condensates with Application to Q-balls
Creators: name: Pawl, Andrew
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Analytical and numerical estimates show that a charged Affleck-Dine condensate will fracture into Q-balls only when the Hubble time is significantly larger than the inverse soft-breaking mass of the field in question. This would generally imply that the decay of the field into light fermions will compete with Q-ball formation. We will show that for typical flat directions the large field value will significantly suppress decays of the condensate to fermions even if no baryon charge asymmetry exists. We will consider the details of the decay process for a condensate that does carry charge, and show that it is qualitatively different from that of an uncharged condensate. Finally, we will consider the possibility of resonant production of heavy bosons. We will show that this can have a strong effect on the condensate. Contrary to intuition, however, our results indicate that boson production would actually assist Q-ball formation in condensates with significant charge.

description: We discuss the effects of superfluidity on the shear viscosity in a neutron star core. Our study combines existing theoretical results for the viscosity coefficients with data for the various superfluid energy gaps into a consistent description. In particular, we provide a simple model for the electron viscosity which is relevant both when the protons form a normal fluid and when they become superconducting. This model explains in a clear way why proton superconductivity leads to a significant strengthening of the shear viscosity. We present our results in a form which permits the use of data for any given modern equation of state (our final formulas are explicitly dependent on the proton fraction). We discuss a simple description of the relevant superfluid pairing gaps, and construct a number of models (spanning the range of current uncertainty) which are then used to discuss the superfluid suppression of shear viscosity. We conclude by a discussion of a number of challenges that must be met if we are to make further progress in this area of research.

O objetivo do presente trabalho foi mensurar a concentração do crédito agrícola na Bahia, dividido em suas mesorregiões, no período de 1999 a 2003. Para tanto, utilizou-se a metodologia do índice T de Theil e da análise tabular dos dados. Os resultados demonstraram concentração do crédito entre as mesorregiões baianas. Apesar de se verificar concentração do crédito pela análise tabular, esta não foi fortemente caracterizada pelo índice T de Theil, que mensurou a distribuição do crédito em relação ao valor da produção. A despeito da elevação do índice no período analisado, verificou-se que esta ainda é baixa em comparação ao seu valor máximo.------------------------------The rural credit is one of the most important agricultural policy finance, however the resources have been distributed in an inequality way, benefiting the brazilian south and southeast regions. This article aims to mensurate the rural credit concentration in the Bahia state, it was divided in its 7 (seven) “mesorregiões”, in the period from 1999 to 2003. Tabular analysis, estimation of Theil T index were used as the basic analytical techniques for the study. The main results of the research show concentration among the “mesorregiões” by tabular analysis, but analyzing by Theil index, this concentration was not perceived. They differ because the Theil index consider the relationship between the credit distribution and agricultural production value. Despite of the elevation in the Theil index in the full period, note that the concentration is lower faced with his higher value.

description: In this work, the impact of field stress on Li7La3Zr2O12 (LLZO) polycrystalline pellets and single crystals was investigated. Voltages of up to a few V were applied using metal electrodes at elevated temperatures in different gas atmospheres (argon and air). The electrochemical processes induced by field stress were investigated by a combination of impedance spectroscopy and chemical analysis. Local conductivities were determined using circular thin film micro-electrodes prepared by photolithography and ion-beam etching. Laterally resolved elemental compositions of the samples were measured by laser-induced breakdown spectroscopy (LIBS). The correlation between changes in electrical properties and chemical composition is discussed. Moreover, electrochemical properties of Li containing oxide thin film electrodes on LLZO were investigated by means of impedance spectroscopy and DC-cycling. In order to prepare such electrodes (e.g. LiMn2O4 and Li4Ti5O12) a RF sputtering device was built and tested for different materials. Influence of the substrate temperature on the properties of the thin films were investigated. All solid state cells were built with Ta-doped LLZO single crystals and polycrystals and reversible electrochemical (dis)charging of the oxide electrodes was demonstrated.

description: Conversational search is one of the ultimate goals of information retrieval. Recent research approaches conversational search by simplified settings of response ranking and conversational question answering, where an answer is either selected from a given candidate set or extracted from a given passage. These simplifications neglect the fundamental role of retrieval in conversational search. To address this limitation, we introduce an open-retrieval conversational question answering (ORConvQA) setting, where we learn to retrieve evidence from a large collection before extracting answers, as a further step towards building functional conversational search systems. We create a dataset, OR-QuAC, to facilitate research on ORConvQA. We build an end-to-end system for ORConvQA, featuring a retriever, a reranker, and a reader that are all based on Transformers. Our extensive experiments on OR-QuAC demonstrate that a learnable retriever is crucial for ORConvQA. We further show that our system can make a substantial improvement when we enable history modeling in all system components. Moreover, we show that the reranker component contributes to the model performance by providing a regularization effect. Finally, further in-depth analyses are performed to provide new insights into ORConvQA.

description: Neste artigo avaliamos a viabilidade econômica do ecoturismo e sua eficácia como alternativa para a conservação da diversidade biológica em áreas protegidas. Usamos como objeto de estudo a Reserva Particular do Patrimônio Natural (RPPN) Pousada das Araras, localizada no município de Serranópolis, no oeste do Estado de Goiás, Brasil. Essa RPPN foi selecionada por apresentar elevada diversidade biológica aliada à beleza cênica de grande valor, com recursos histórico-culturais de especial relevância. Pelo lado dos custos da conservação da diversidade biológica o principal componente foi o custo de oportunidade (CO) das atividades produtivas que não estão sendo desenvolvidas nesta área de RPPN. Assim, o CO da conservação da biodiversidade foi dado pelos benefícios sacrificados de uma possível atividade agrícola, a cana-de-açúcar. Os benefícios líquidos da RPPN foram expressos pelos benefícios menos custos da atividade de ecoturismo nesta RPPN. Nossos resultados mostram que a RPPN só é viável economicamente se ela receber um fluxo contínuo e satisfatório de ecoturistas. Dito de outra maneira, os diferentes produtos ecoturísticos ofertados precisam atrair uma demanda significativa para que o ecoturismo se torne uma alternativa econômica relevante para o empreendedor privado de uma RPPN. Só assim proprietário particular e sociedade em seu conjunto podem garantir benéficos mútuos da conservação da biodiversidade. Caso a hipótese de nível e continuidade de fluxo de turistas não se confirmar, há necessidade de políticas públicas que orientem e auxiliem proprietários privados a desenvolver ecoturismo de modo eficaz e eficiente para a conservação da diversidade biológica. ------------------In this paper we evaluate the economic feasibility of ecotourism and its effectiveness to biological diversity conservation in protected areas. We use the Private Reserve of Natural Asset (RPPN) of Pousada das Araras as case study. This RPPN is located in the count y of Serranópolis, in the west portion of the State of Goiás, Brazil. It was chosen due to its high diversity of biological diversity and to its outstanding natural beauty. As far as economic estimates are concerned, the main cost component was the opportunity cost of sacrificed production. In our estimates, sugar-cane was chosen as the alternative land use. Net benefits of the RPPN were estimated as ecotourism benefits minus costs. Our results show that ecotourism in RPPNs is a economic sound activity if and only if it receives a significant flow of tourist throughout the year. If a continuous flow of tourists is not observed, it is necessary to draw and implement policies to incentive private entrepreneurs to develop ecotourism activities in their properties.
Project summary: The STEM Good Tutor Guide

Subjects: Scholarship of Teaching and Learning

description: It has been 20 years since the university published Supporting Open Learners: Reader, and the accompanying publication, Supporting Open Learners: Theoretical Reader for its tutors. These booklets offer practical guidance about many aspects of the role as a tutor. Two years later, the university published booklets on subjects, such as correspondence tuition (intranet only). Given the amount of substantial change that has taken place in the last 20 years, there is the need for a new up-to-date tutor resource that shares best practice, whilst also drawing on research carried out by the scholarship centres. Alluding to the title of Andrew Northedge’s student focussed The Good Study Guide, the aim of this scholarship project is to create a new resource entitled The Good Tutor Guide (TGTG). This project will aim to solicit opinions about tutor needs through university, faculty and school AL development events and to evaluate the first draft of The Good Tutor Guide, with a view to preparing a second edition. The project will also draw on the existing Guides for Associate Lecturer booklets (intranet only) which were last updated nearly ten years ago.The new guide will be published under a creative commons licence and made available as an Open Educational Resource (OER) so it can be edited and adapted by other members of the university. It is envisaged that TGTG will be initially made available in a number of different formats: a PDF, an ePub for use on e-readers, and a physical booklet. All three formats will be evaluated.

description: For two convex bodies K and T in $R^n$, the covering number of K by T, denoted N(K,T), is defined as the minimal number of translates of T needed to cover K. Let us denote by $K^o$ the polar body of K and by D the euclidean unit ball in $R^n$. We prove that the two functions of t, N(K, tD) and N(D, tK^o), are equivalent in the appropriate sense, uniformly over symmetric convex bodies K in $R^n$ and over positive integers n. In particular, this verifies the duality conjecture for entropy numbers of linear operators, posed by Pietsch in 1972, in the central case when either the domain or the range of the operator is a Hilbert space.

Treatment of obesity and diabetes by a regulatable leptin cell therapy system

description: Obesity, a chronic disorder that is increasing in prevalence worldwide, is a major risk factor for the development of type 2 diabetes, a metabolic disorder characterized by hyperglycemia. In this thesis, the efficacy of a leptin cell therapy was evaluated for the treatment of obesity and diabetes in leptin-deficient ob/ob mice and in high fat fed, leptin-resistant C57BL/6J mice. A gut endocrine K-cell line was engineered to produce leptin under the regulation of an RU486 controlled GeneSwitch™ system. In culture, these cells express and release leptin in an RU486 dose- and time-dependent manner. These cells were transplanted into ob/ob mice via (a) kidney capsule and (b) intraperitoneal (IP) injection of alginate encapsulated cells along with 14-day RU486 pellets. In mice that received leptin-producing cells under the kidney capsule, reductions in body weight (10%), food intake (50%) and blood glucose levels (67%) were observed 10 days post-transpjant, relative to controls. Body weight and food intake rapidly increased thereafter to that of controls. Interestingly, however, blood glucose concentrations remained reduced by 40% up to 2 weeks post-transplantation. Animals given IP encapsulated cells lost up to 17% of body weight and then rapidly returned to their starting weight 14 days later at exhaustion of the RU486. Remarkably, despite the fact that body weight was completely regained within 20 days posttransplantation, blood glucose concentrations remained reduced by almost 70% up to 50 days post-transplantation. Both the number of transplanted cells and the dose of RU486 given could regulate the effects of leptin cell therapy. Obese C57BL/6J mice on a high fat diet did not respond with reductions in body weight, food intake or blood glucose levels after being transplanted with encapsulated leptin-producing gut cells. These data demonstrate that leptin administered via a cell therapy strategy can result in a reduction in body weight, food intake and long term corrections of blood glucose concentrations in leptin sensitive ob/ob mice but not in high fat fed leptin resistant C57BL/6J mice under the conditions tested.

Energy barrier for collapse in a pair of tunnel-coupled condensates with the scattering lengths of opposite signs

description: We predict the existence of an energy barrier for collapse in a system of two tunnel-coupled repulsive and attractive quasi two-dimensional condensates trapped in a double-well potential. The ground state in such a system can have a lower energy than that of the collapsing state. We find such ground states numerically and analytically determine the domain of their existence, they have a much larger share of atoms confined in the repulsive condensate. The energy barrier for collapse is due to the fact that the energy of the system increases if atoms tunnel from the repulsive condensate to the attractive one.

description: Holographic Predictive Search (HPS) is a novel approach to search-based hologram generation that uses a mathematical understanding of the optical transforms to make informed optimisation decisions. Existing search techniques such as Direct Search (DS) and Simulated Annealing (SA) rely on trialling modifications to a test hologram and observing the results. A formula is used to decide whether the change should be accepted. HPS operates presciently, using knowledge of the underlying mathematical relationship to make exact changes to the test hologram that guarantee the 'best' outcome for that change. In this work, we extend the scope of the original research to cover both phase and amplitude modulating Spatial Light Modulators (SLMs), both phase sensitive and phase insensitive systems and both Fresnel and Fraunhofer diffraction. In the cases discussed, improvements of up to 10x are observed in final error and the approach also offers significant performance benefits in generation time. This comes at the expense of increased complexity and loss of generality.

description: The development of mathematical simulation and optimization models and algorithms for solving gas transport problems is an active field of research. In order to test and compare these models and algorithms, gas network instances together with demand data are needed. The goal of GasLib is to provide a set of publicly available gas network instances that can be used by researchers in the field of gas transport. The advantages are that researchers save time by using these instances and that different models and algorithms can be compared on the same specified test sets. The library instances are encoded in an XML (extensible markup language) format. In this paper, we explain this format and present the instances that are available in the library.
