Improving the impact of luminance contrast on the window appearance in a conventional office room: Using supplementary lighting strategies

High contrast ratios between windows and surrounding surfaces could cause reduced visibility or discomfort for occupants. Consequently, building users may choose to intervene in lighting conditions through closing blinds and turning on the lamps in order to enhance indoor visual comfort. Such interventions increase projected electric lighting use in buildings. One simple method to prevent these problematic issues is increasing the luminance of the areas surrounding to the bright surface of windows through the use of energy-efficient supplementary lighting, such Light Emitting Diodes (LEDs). This paper reports on the results of a pilot study in conventional office in Brisbane, Australia. The outcomes of this study indicated that a supplementary LED system of approximately 18 W could reduce the luminance contrast on the window wall from values in the order of 117:1 to 33:1. In addition, the results of this experiment suggested that this supplementary strategy could increase the subjective scale appraisal of window appearance by approximately 33%, as well as reducing the likelihood of users’ intention to turn on the ceiling lights by about 27%. It could also diminish the likelihood of occupants’ intention to move the blind down by more than 90%.

Agreement Patterns in English : Diachronic Corpus Studies on Common-Number Pronouns

This study reports a diachronic corpus investigation of common-number pronouns used to convey unknown or otherwise unspecified reference. The study charts agreement patterns in these pronouns in various diachronic and synchronic corpora. The objective is to provide base-line data on variant frequencies and distributions in the history of English, as there are no previous systematic corpus-based observations on this topic. This study seeks to answer the questions of how pronoun use is linked with the overall typological development in English and how their diachronic evolution is embedded in the linguistic and social structures in which they are used. The theoretical framework draws on corpus linguistics and historical sociolinguistics, grammaticalisation, diachronic typology, and multivariate analysis of modelling sociolinguistic variation. The method employs quantitative corpus analyses from two main electronic corpora, one from Modern English and the other from Present-day English. The Modern English material is the Corpus of Early English Correspondence, and the time frame covered is 1500-1800. The written component of the British National Corpus is used in the Present-day English investigations. In addition, the study draws supplementary data from other electronic corpora. The material is used to compare the frequencies and distributions of common-number pronouns between these two time periods. The study limits the common-number uses to two subsystems, one anaphoric to grammatically singular antecedents and one cataphoric, in which the pronoun is followed by a relative clause. Various statistical tools are used to process the data, ranging from cross-tabulations to multivariate VARBRUL analyses in which the effects of sociolinguistic and systemic parameters are assessed to model their impact on the dependent variable. This study shows how one pronoun type has extended its uses in both subsystems, an increase linked with grammaticalisation and the changes in other pronouns in English through the centuries. The variationist sociolinguistic analysis charts how grammaticalisation in the subsystems is embedded in the linguistic and social structures in which the pronouns are used. The study suggests a scale of two statistical generalisations of various sociolinguistic factors which contribute to grammaticalisation and its embedding at various stages of the process.

Uzbekistan Supplementary NGO Report on the Implementation of the Convention on the Rights of the Child in the Republic of Uzbekistan

[Excerpt] The Convention on the Rights of the Child (CRC) was one of the first international instruments to which the Republic of Uzbekistan acceded, and with parliamentary ratification on 9 December 1992, the Republic of Uzbekistan entered into a commitment to observe all the provisions of the CRC and to shoulder its responsibility before the international community. As a result various legislative, administrative and other steps have been taken by the government of the Republic of Uzbekistan with a view to bringing the State policy and legislation on children to be in line with the provisions as enshrined in the Convention on the Rights of the Child. The Constitution incorporates the fundamental provisions of the Universal Declaration of Human Rights. At the current stage in the restructuring of the country’s social and economic development, solid foundations have been laid for the conduct of significant democratic reforms based on a recognition of the innate worth of the individual (including the child) and of the unconditional respect of his or her rights and freedoms. Until recently, the State acted as the main guarantor of the provision of all social services, however the process of the transition (political/economic) to a market economy has entailed the development of new economic relations with a reduction in the allocation of state resources for the provision of social services to children. The efforts of the government made so far to bring the state policy and legislation on the child to be in line with the provisions enshrined in the convention on the rights of the child are commendable; never the less, the implementations of all these policies and laws into practice needs a lot to desire as there are a number of ongoing child rights violations. The National Report has fundamentally overlooked a number of child rights privileges enshrined in the CRC that have not yet been realised, or those rights that have been eroded since the independence. These shortcomings need to be noted for consideration so that the state steps up its efforts to enact new laws and/or to enforce the existing rules and regulations required for the protection and implementation of these child rights, and to improve the overall situation for children in the Republic of Uzbekistan.

Localization of feeding of Anomalococcus indicus (Hemiptera: Lecanodiaspididae) and supplementary biological notes: Towards the biological management of the invasive tree Vachellia nilotica indica (Fabales: Mimosoideae) in North-Eastern Australia

. Management of the invasive Vachellia nilotica indica infesting tropical grasslands of Northern Australia has remained unsuccessful to date. Presently Anomalococcus indicus is considered a potential agent in the biological management of V. n. indica. Whereas generic biological details of A. indicus have been known, their feeding activity and details of their mouthparts and the sensory structures that are associated with their feeding action are not known. This paper provides details of those gaps. Nymphal instars I and II feed on cortical-parenchyma cells of young stems of V. n. indica, whereas nymphal instars III and adult females feed on phloem elements of older shoots. Nymphal instars and adults (females) trigger stress symptoms in the feeding tissue with cells bearing enlarged and disfigured nuclei, cytoplasmic shrinkage, cytoplasmic trabeculae, abnormal protuberances and uneven cell wall thickening, unusual cell membrane proliferation, and exhausted and necrosed cells. Continuous nutrient extraction by A. indicus can cause stem death. We provide evidence that A. indicus, by virtue of its continuous feeding activity and intense population build up, can be an effective biological-management agent to regulate populations of V. n. indica in infested areas. © 2014 © 2014 Société entomologique de France.

Conservation of Atlantic salmon by supplementary stocking of juvenile fish

Wild salmon stocks in the northern Baltic rivers became endangered in the second half of the 20th century, mainly due to recruitment overfishing. As a result, supplementary stocking was widely practised, and supplementation of the Tornionjoki salmon stock took place over a 25 year period until 2002. The stock has been closely monitored by electrofishing, smolt trapping, mark-recapture studies, catch samples and catch surveys. Background information on hatchery-reared stocked juveniles was also collected for this study. Bayesian statistics was applied to the data as this method offers the possibility of bringing prior information into the analysis and an advanced ability for incorporating uncertainty, and also provides probabilities for a multitude of hypotheses. Substantial divergences between reared and wild Tornionjoki salmon were identified in both demographic and phenological characteristics. The divergences tended to be larger the longer the duration spent in hatchery and the more favourable the hatchery conditions were for fast growth. Differences in environment likely induced most of the divergences, but selection of brood fish might have resulted in genotypic divergence in maturation age of reared salmon. Survival of stocked 1-year old juveniles to smolt varied from about 10% to about 25%. Stocking on the lower reach of the river seemed to decrease survival, and the negative effect of stocking volume on survival raises the concern of possible similar effects on the extant wild population. Post-smolt survival of wild Tornionjoki smolts was on average two times higher than that of smolts stocked as parr and 2.5 times higher than that of stocked smolts. Smolts of different groups showed synchronous variation and similar long-term survival trends. Both groups of reared salmon were more vulnerable to offshore driftnet and coastal trapnet fishing than wild salmon. Average survival from smolt to spawners of wild salmon was 2.8 times higher than that of salmon stocked as parr and 3.3 times higher than that of salmon stocked as smolts. Wild salmon and salmon stocked as parr were found to have similar lifetime survival rates, while stocked smolts have a lifetime survival rate over 4 times higher than the two other groups. If eggs are collected from the wild brood fish, stocking parr would therefore not be a sensible option. Stocking smolts instead would create a net benefit in terms of the number of spawners, but this strategy has serious drawbacks and risks associated with the larger phenotypic and demographic divergences from wild salmon. Supplementation was shown not to be the key factor behind the recovery of the Tornionjoki and other northern Baltic salmon stocks. Instead, a combination of restrictions in the sea fishery and simultaneous occurrence of favourable natural conditions for survival were the main reasons for the revival in the 1990 s. This study questions the effectiveness of supplementation as a conservation management tool. The benefits of supplementation seem at best limited. Relatively high occurrences of reared fish in catches may generate false optimism concerning the effects of supplementation. Supplementation may lead to genetic risks due to problems in brood fish collection and artificial rearing with relaxed natural selection and domestication. Appropriate management of fisheries is the main alternative to supplementation, without which all other efforts for long-term maintenance of a healthy fish resource fail.

Fuzzy logic based TCSC supplementary controller for damping of inter area oscillations in power system

This paper describes an application of a FACTS supplementary controller for damping of inter area oscillations in power systems. A fuzzy logic controller is designed to regulate a thyristor controlled series capacitor (TCSC) in a multimachine environment to produce additional damping in the system. Simultaneous application of the excitation controller and proposed controller is also investigated. Simulation studies have been done with different types of disturbances and the results are shown to be consistent with the expected performance of the supplementary controller.

Proactive control of sequential saccades in the human supplementary eye field

Our ability to regulate behavior based on past experience has thus far been examined using single movements. However, natural behavior typically involves a sequence of movements. Here, we examined the effect of previous trial type on the concurrent planning of sequential saccades using a unique paradigm. The task consisted of two trial types: no-shift trials, which implicitly encouraged the concurrent preparation of the second saccade in a subsequent trial; and target-shift trials, which implicitly discouraged the same in the next trial. Using the intersaccadic interval as an index of concurrent planning, we found evidence for context-based preparation of sequential saccades. We also used functional MRI-guided, single-pulse, transcranial magnetic stimulation on human subjects to test the role of the supplementary eye field (SEF) in the proactive control of sequential eye movements. Results showed that (i) stimulating the SEF in the previous trial disrupted the previous trial type-based preparation of the second saccade in the nonstimulated current trial, (ii) stimulating the SEF in the current trial rectified the disruptive effect caused by stimulation in the previous trial, and (iii) stimulating the SEF facilitated the preparation of second saccades based on previous trial type even when the previous trial was not stimulated. Taken together, we show how the human SEF is causally involved in proactive preparation of sequential saccades.

Cluster labeling for multilingual scatter/gather using comparable corpora

Scatter/Gather systems are increasingly becoming useful in browsing document corpora. Usability of the present-day systems are restricted to monolingual corpora, and their methods for clustering and labeling do not easily extend to the multilingual setting, especially in the absence of dictionaries/machine translation. In this paper, we study the cluster labeling problem for multilingual corpora in the absence of machine translation, but using comparable corpora. Using a variational approach, we show that multilingual topic models can effectively handle the cluster labeling problem, which in turn allows us to design a novel Scatter/Gather system ShoBha. Experimental results on three datasets, namely the Canadian Hansards corpus, the entire overlapping Wikipedia of English, Hindi and Bengali articles, and a trilingual news corpus containing 41,000 articles, confirm the utility of the proposed system.

Translation Induction on Indian Language Corpora Using Translingual Themes from Other Languages

Identifying translations from comparable corpora is a well-known problem with several applications, e.g. dictionary creation in resource-scarce languages. Scarcity of high quality corpora, especially in Indian languages, makes this problem hard, e.g. state-of-the-art techniques achieve a mean reciprocal rank (MRR) of 0.66 for English-Italian, and a mere 0.187 for Telugu-Kannada. There exist comparable corpora in many Indian languages with other ``auxiliary'' languages. We observe that translations have many topically related words in common in the auxiliary language. To model this, we define the notion of a translingual theme, a set of topically related words from auxiliary language corpora, and present a probabilistic framework for translation induction. Extensive experiments on 35 comparable corpora using English and French as auxiliary languages show that this approach can yield dramatic improvements in performance (e.g. MRR improves by 124% to 0.419 for Telugu-Kannada). A user study on WikiTSu, a system for cross-lingual Wikipedia title suggestion that uses our approach, shows a 20% improvement in the quality of titles suggested.

Prosa argumentativa em língua inglesa: um estudo contrastivo sobre advérbios em corpora digitais

Esta pesquisa tem como objetivo principal investigar como aprendizes brasileiros de língua inglesa usam advérbios com terminação em ly no inglês escrito, e comparar ao uso que deles fazem os falantes de inglês como língua materna. Para tanto, o trabalho encontra suporte teórico e metodológico na Linguística de Corpus e fundamenta-se na área chamada de pesquisa sobre corpora de aprendizes, que se ocupa da coleta e armazenagem de dados linguísticos de sujeitos aprendizes de uma língua estrangeira, para a formação de um corpus que possa ser utilizado para fins descritivos e pedagógicos. Esta área objetiva identificar em que aspectos os aprendizes diferem ou se assemelham aos falantes nativos. Os corpora empregados na pesquisa são o corpus de estudo (Br-ICLE), contendo inglês escrito por brasileiros, compilado de acordo com o projeto ICLE (International Corpus of Learner English) e dois corpora de referência (LOCNESS e BAWE), contendo inglês escrito por falantes de inglês como língua materna. Os resultados indicam que os alunos brasileiros usam, em demasia, as categorias de advérbios que indicam veracidade, realidade e intensidade, em relação ao uso que deles fazem os falantes nativos, além de usarem esses advérbios de forma distinta. Os resultados sugerem que, além das diferenças apresentadas em termos de frequência (seja pelo sobreuso ou subuso dos advérbios), os aprendizes apresentavam combinações errôneas, ou em termos de colocados ou em termos de prosódia semântica. E finalmente a pesquisa revela que a preferência dos aprendizes por advérbios que exprimem veracidade, realidade e intensidade cria a impressão de um discurso muito assertivo. Conclui-se que as diferenças encontradas podem estar ligadas a fatores como o tamanho dos corpora, a influência da língua materna dos aprendizes, a internalização dos elementos linguísticos necessários para a produção de um texto em língua estrangeira, a falta de fluência dos aprendizes e o contexto de sala de aula nas universidades

Memes pluralistas práticas linguístico-midiáticas em fenômenos bilíngues: um estudo sistêmico-funcional e multimodal sobre propagação via corpora digitais

Investigou-se pelo presente estudo se a concepção presente na Teoria de Replicadores, expressa através do conceito de meme (DAWKINS, 1979), poderia ser um modelo compatível para explicar a propagação de memes no substrato das mídias sociais. No âmbito dos estudos locais, Recuero (2006) sugeriu uma transdução desse modelo, baseando-se nas concepções de Dawkins (1979). Refletindo sobre o posicionamento epistemológico de Recuero (2006), o presente trabalho, baseando-se em Dennett (1995), Blackmore (2002) e Tyler (2011b; 2013b), procedeu às instâncias de Análise Conceitual e Composicional dessa transdução. A partir do conceito de memeplexo (BLACKMORE, 2002), esta pesquisa de base linguística (HALLIDAY, 1987) entende os memes, no substrato das mídias digitais/sociais, como práticas de produção e distribuição linguístico-midiáticas, propaladas a partir de diversas unidades de propagação e das relações criadas pelos internautas nesse processo de transmissão. Investigando tais relações, a partir da instância de Análise Relacional, propõe-se examinar duas unidades de propagação. Expressões meméticas (Que deselegante e #Tenso) e imagens meméticas (oriundas do fenômeno memético Nana em desastres). Integram este estudo dois corpora de expressões meméticas (5275 postagens oriundas ou redirecionadas para o Twitter.com total de 83.655 palavras/tokens) e um corpus bilíngue (Português/Inglês) de imagens meméticas (um total de 134 imagens oriundas do Tumblr.com e Facebook.com). Para analisar os corpora de expressões meméticas utilizou-se a metodologia de Linguística de Corpus (BERBER-SARDINHA, 2004; SHEPHERD, 2009; SOUZA JÚNIOR, 2012, 2013b, 2013c). Para a análise do corpus multimodal de imagens meméticas, utilizou-se a metodologia que chamamos de Análise Propagatória. Objetivamos verificar se essas unidades de propagação e as práticas linguístico-midiáticas que estas transmitem, evoluiriam somente devido a aspectos memético-midiáticos, conforme Recuero (2006) apontara, e com padrão de propagação internalista (DAWKINS, 1979; 1982). Após análise dos dados, revelou-se que, ao nível do propósito, os fenômenos locais investigados não evoluíram por padrão internalista (ou homogêneo) de propagação. Tais padrões revelam ser de natureza externalista (ou heterogênea). Ademais, constatou-se que princípios constitutivos meméticos de evolução como os de fecundidade, longevidade (DAWKINS 1979; 1982) e o de design (DENNETT, 1995), junto com o princípio midiático de evolução de alcance (RECUERO, 2006) mantiveram-se presentes com alto grau de influencia nas propagações de natureza externalista. Por outro lado, o princípio memético da fidelidade (DAWKINS, 1979; 1982) foi o que menos influenciou esses padrões de propagação. Neutralizando a fidelidade, e impulsionados pelo princípio de design, destacaram-se nesse processo evolutivo os princípios linguísticos sistematizadores revelados por este estudo. Isto é: o princípio da funcionalidade (memes evoluem porque podem indicar propósitos diferentes) e o princípio do alcance linguístico (memes podem ser direcionados a itens animados/ inanimados; para internautas em idioma nativo/ estrangeiro)

Heterotrophic marine bacteria as supplementary feed for larval Penaeus monodon

The findings are presented of a study conducted to use autochthonously obtained, nonpathogenic heterotrophic marine bacteria as a substitute feed for microalgae in rearing larval Penaeus monodon. Eleven strains were isolated: Micrococcus (MCC), Staphylococcus, Streptococcus, Bacillus (two strains; BAC-1, BAC-2), Pseudomonas (two strains; PSM-1, PSM-2), Vibrio parahemolyticus, V. fluviatilis, Moraxella (MOR) and Flavobacterium. Six nonhemolytic strains were then chosen for the Penaeus monodon larval feed trials: BAC-1, BAC-2, PSM-1, PSM-2, MCC and MOR. The study demonstrates that bacterial biomass could be further investigated as a partial substitute for microalgae in penaeid shrimp larval rearing.
