[Book] The potential of electric light as a new building “material” was recognized in the 1920s and became a useful design tool by the mid-century. Skillful lighting allowed for theatricality, narrative, and a new emphasis on structure and space. The Structure of Light tells the story of the career of Richard Kelly, the field’s most influential figure. Six historians, architects, and practitioners explore Kelly’s unparalleled influence on modern architecture and his lighting designs for some of the 20th century’s most iconic buildings: Philip Johnson’s Glass House; Louis Kahn’s Kimbell Art Museum; Eero Saarinen’s GM Technical Center; and Mies van der Rohe’s Seagram Building, among many others. This beautifully illustrated history demonstrates the range of applications, building types, and artistic solutions he employed to achieve a “nocturnal modernity” that would render buildings evocatively different at night. The survival of Kelly’s rich correspondence and extensive diaries allows an in-depth look at the triumphs and uncertainties of a young profession in the making. The first book to focus on the contributions of a master in the field of architectural lighting, this fascinating volume celebrates the practice’s significance in modern design.

The language of lighting design

From 23 August until 2 October 2010, the successful Richard Kelly exhibition and symposium held at the Yale Architecture School in New Haven, US drew attention to the many contributions of this pioneering designer. Luminous opens the debate with five international lighting designers on the role and relevance of Kelly's vocabulary today.

Näkökulmia eurooppalaiseen sosiaalipolitiikkaan : malli, väestö, resurssit ja kommunikaatio

The study analyses European social policy as a political project that proceeds under the guidance of the European Commission. In the name of modernisation, the project aims to build a new idea for the welfare state. To understand the project, it is necessary to distance oneself from both the juridical competence of the European Union and the traditional national welfare state models. The question is about sharing problems, as well as solutions to them: it is the creation and sharing of common views, concepts and images that play a key role in European integration. Drawing on texts and speeches produced by the European Commission, the study throws light on the development of European social policy during the first years of the 2000s. The study "freeze-frames" the welfare debate having its starting points in the nation states in the name of the entity of Europe. The first article approaches the European social model as a story in itself, a preparatory, persuasive narrative that concerns the management of change. The article shows how the audience can be motivated to work towards a set target by using discursive elements in a persuasive manner: the function of a persuasive story is to convince the target audience of the appropriateness of the chosen direction and to shape their identity so that they are favourably disposed to the desired political targets. This is a kind of "intermediate state" where the story, despite its inner contradictions and inaccuracies, succeeds in appearing as an almost self-evident path towards a modern social policy that Europe is currently seen to be in need of. The second article outlines the European social model as a question of governance. Health as a sector of social policy is detached from the old political order, which was based on the welfare state, and is closely linked to economy. At the same time the population is primarily seen as an economic resource. The Commission is working towards a "Europe of Health" that grapples with the problem of governance with the help of the "healthisation" of society, healthy citizenship and health economics. The way the Commission speaks is guided by the Union's powerful interest to act as "Europe" in the field of welfare policy. At the same time, the traditional separateness of health policy is effaced in order to be able to make health policy reforms a part of the Union's wider modernisation targets. The third article then shows the European social policy as its own area of governance. The article uses an approach based on critical discourse analysis in examining the classification systems and presentation styles adopted by Commission communications, as well as the identities that they help build. In analysing the "new start" of the Lisbon strategy from the perspective of social policy, the article shows how the emphasis has shifted from the persuasive arguments for change with necessary common European targets in the early stages of the strategy towards the implementation of reforms: from a narrative to a vision and from a diagnosis to healing. The phase of global competition represents "the modern" with which European society with its culture and ways of life now has to be matched. The Lisbon strategy is a way to direct this societal change, thus building a modern European social policy. The fourth article describes how the Commission uses its communications policy to build practices and techniques of governance and how it persuades citizens to participate in the creation of a European project of change. This also requires a new kind of agency: agents for whom accountability and responsibilities mean integration into and commitment to European society. Accountability is shaped into a decisive factor in implementing the European Union's strategy of change. As such it will displace hierarchical confrontations and emphasise common action with a view to modernising Europe. However, the Union's discourse cannot be described as being a political language that would genuinely rouse and convince the audience at the level of everyday life. Keywords: European social policy, EU policy, European social model, European Commission, modernisation of welfare, welfare state, communications, discoursiveness.

An analytical model for the capacity estimation of combined VoIP and TCP file transfers over EDCA in an IEEE 802.11e WLAN

In this paper we develop and numerically explore the modeling heuristic of using saturation attempt probabilities as state dependent attempt probabilities in an IEEE 802.11e infrastructure network carrying packet telephone calls and TCP controlled file downloads, using Enhanced Distributed Channel Access (EDCA). We build upon the fixed point analysis and performance insights in [1]. When there are a certain number of nodes of each class contending for the channel (i.e., have nonempty queues), then their attempt probabilities are taken to be those obtained from saturation analysis for that number of nodes. Then we model the system queue dynamics at the network nodes. With the proposed heuristic, the system evolution at channel slot boundaries becomes a Markov renewal process, and regenerative analysis yields the desired performance measures.The results obtained from this approach match well with ns2 simulations. We find that, with the default IEEE 802.11e EDCA parameters for AC 1 and AC 3, the voice call capacity decreases if even one file download is initiated by some station. Subsequently, reducing the voice calls increases the file download capacity almost linearly (by 1/3 Mbps per voice call for the 11 Mbps PHY).

Mammalian neuronal sodium channel Blocker mu-conotoxin BuIIIB has a structured N-terminus that influences potency

Among the mu-conotoxins that block vertebrate voltage-gated sodium channels (VGSCs), some have been shown to be potent analgesics following systemic administration in mice. We have determined the solution structure of a new representative of this family, mu-BuIIIB, and established its disulfide connectivities by direct mass spectrometric collision induced dissociation fragmentation of the peptide with disulfides intact The major oxidative folding product adopts a 1-4/2-5/3-6 pattern with the following disulfide bridges: Cys5-Cys17, Cys6-Cys23, and Cys13-Cys24. The solution structure reveals that the unique N-terminal extension in mu-BuIIIB, which is also present in mu-BuIIIA and mu-BuIIIC but absent in other mu-conotoxins, forms part of a short a-helix encompassing Glu3 to Asn8. This helix is packed against the rest of the toxin and stabilized by the Cys5-Cys17 and Cys6-Cys23 disulfide bonds. As such, the side chain of Val1 is located close to the aromatic rings of Trp16 and His20, which are located on the canonical helix that displays several residues found to be essential for VGSC blockade in related mu-conotoxins. Mutations of residues 2 and 3 in the N-terminal extension enhanced the potency of mu-BuIIIB for Na(v)1.3. One analogue, D-Ala2]BuIIIB, showed a 40-fold increase, making it the most potent peptide blocker of this channel characterized to date and thus a useful new tool with which to characterize this channel. On the basis of previous results for related mu-conotoxins, the dramatic effects of mutations at the N-terminus were unanticipated and suggest that further gains in potency might be achieved by additional modifications of this region.

Mathematical models for the prediction of temperature distributions resulting from the discharge of heated water into large bodies of water

Mathematical models for heated water outfalls were developed for three flow regions. Near the source, the subsurface discharge into a stratified ambient water issuing from a row of buoyant jets was solved with the jet interference included in the analysis. The analysis of the flow zone close to and at intermediate distances from a surface buoyant jet was developed for the two-dimensional and axisymmetric cases. Far away from the source, a passive dispersion model was solved for a two dimensional situation taking into consideration the effects of shear current and vertical changes in diffusivity. A significant result from the surface buoyant jet analysis is the ability to predict the onset and location of an internal hydraulic jump. Prediction can be made simply from the knowledge of the source Froude number and a dimensionless surface exchange coefficient. Parametric computer programs of the above models are also developed as a part of this study. This report was submitted in fulfillment of Contract No. 14-12-570 under the sponsorship of the Federal Water Quality Administration.

Enfim mães!: da experiência da reprodução assistida à experiência da maternidade lésbica

Embora a maternidade lésbica não seja novidade, nos últimos anos sua visibilidade vem aumentando. A ampliação da procura e acesso aos serviços de medicina reprodutiva por casais de mulheres acrescenta novos ingredientes a este cenário, que desperta crescente interesse social. Tão bem arraigada às construções de gênero, a maternidade figura como elemento de fundamental importância em nossa sociedade. Pretendendo tensionar como casais de mulheres que desejam ser mães a partir do acesso às técnicas de reprodução assistida se relacionam com a maternidade e com o serviço de saúde, realizamos entrevistas com cinco casais de mulheres residentes de cidades do Rio de Janeiro e de São Paulo, bem como com seis profissionais de saúde de um centro de medicina reprodutiva localizado na cidade do Rio de Janeiro. Mesmo o processo tendo sido longo e dispendioso para muitas, parece a maternidade autorizar manipulações e intervenções profissionais. Ainda que os profissionais entrevistados recebam casais lésbicos e prestem atendimento, as desconfianças sobre a legitimidade desta composição familiar não são poucas. A maternidade ressignificou a vida dessas mulheres, acrescentando novas dinâmicas às relações familiares e conjugais. Todavia, sob olhares que desconfiam e tolhidas de direitos, estas famílias enfrentam lutas judiciais e se articulam para responder as desconfianças.

Revisão taxonômica das espécies brasileiras de Funariaceae Schwagr. (Bryophyta)

Funariaceae Schwägrichen é uma família de musgos cosmopolita que crescem em diversos habitats, por um ou raramente dois anos, mas algumas espécies podem ser perenes. Possuem como característica marcante o gametófito uniforme e uma ampla diversidade na arquitetura do esporófito. Este estudo realizou a revisão taxonômica da família Funariaceae no Brasil através da análise dos espécimes-tipos de coleções de herbários, nacionais e internacionais, e consulta a literatura específica sobre os táxons. É apresentada uma listagem revista e atualizada da família Funariaceae que ocorrem no Brasil, chaves de identificação para gêneros e espécies, descrições morfológicas, distribuição geográfica, status de conservação, ecologia, comentários, relação do material examinado e ilustrações. Para o Brasil eram citados 51 binômios agrupados em três gêneros: Entosthodon Schwagr. (11 binômios), Funaria Hedw. (20 binômios) e Physcomitrium (Brid.) Brid. (20 binômios). Os gêneros são taxonomicamente distintos pelo tipo de ornamentação dos esporos, forma da cápsula, forma das células do exotécio, presença ou ausência de peristômio, comprimento da seta, forma do ânulo e forma da caliptra. Após a revisão dos nomes foi estabelecida uma combinação nova a partir de Funaria ramulosa (Hampe) Paris: Entosthodon ramulosus (Hampe) M. S. Dias & D. F. Peralta. Foram estabelecidos 10 novos sinônimos: Funaria luteolimbata Broth. F. obtusa-apiculata Müll. Hal. e F. ramulosa (Hampe) Paris como sinônimos de Entosthodon ramulosus (Hampe) M. S. Dias & D. F. Peralta; Physcomitrium flavum (Müll. Hal.) Broth. como sinônimo de E. bonplandii (Hook.) Mitt.; Physcomitrium badium Broth. como sinônimo de P. umbonatum Mitt.; P. lindmanii Broth., P. sylvestre Müll. Hal. e P. convolutaceum Müll. Hal. como sinônimos de P. thieleanum Hampe. P. serrulatum Mitt., P. cupulare Müll Hal. e P. platyphylloides Paris como sinônimos de P. subsphaericum Schimp. Entosthodon puiggarii Geh. & Hampe é o nome legítimo do táxon Physcomitrium puiggarii Geh & Hampe e foi constatado que Funaria capillipes (Müll. Hal. ex Broth.) Broth., é uma combinação inválida. Seis táxons foram excluídos de Funariaceae por não possuírem os caracteres morfológicos diagnósticos da família e seis espécies não foram incluídas no tratamento taxonômico por falta de informação sobre as mesmas e foram consideradas como espécies duvidosas. Portanto, são reconhecidos para o Brasil 11 táxons em Funariaceae: quatro de Entosthodon (E. bonplandii (Hook.) Mitt., E. obtusifolius Hook. f. in Hooker, E. puiggarii Geh. & Hampe in Hampe & Geheeb. e E. ramulosus (Hampe) M. S. Dias & D. F. Peralta); dois de Funaria (F. calvescens Schwagr. e F. hygrometrica Hedw.) e cinco de Physcomitrium (P. capillipes Müll. Hal. ex Broth., P. falcifolium Müll. Hal. in Brotherus, P. umbonatum Mitt., P. subsphaericum Schimp. e P. thieleanum Hampe). Cinco táxons são endêmicos do Brasil: Entosthodon puiggarii, E. ramulosus, Physcomitrium capillipes, P. falcifolium, P. umbonatum e a espécie P. capillipes é conhecida apenas pelo tipo nomenclatural. A partir da análise de diversos materiais originais, é apresentada aqui uma nova reinterpretação da família Funariaceae do Brasil, com novas sinonimizações, reconhecimento de uma nova combinação, e lectótipos

A responsabilidade dos pais pelos atos dos filhos menores

Trata-se de estudo sobre a responsabilidade dos pais em caso de ato ilícito cometido pelo filho menor. Nos termos do artigo 932, I, do atual Código Civil brasileiro, os pais respondem pelos atos dos filhos que estiverem sob sua autoridade e em sua companhia. Nesse sentido, intenta-se esclarecer conceitos como paternidade, autoridade e companhia a fim de melhor compreender o alcance da norma. O exercício da autoridade parental e a garantia da vítima serão apresentados como fundamentos do dever dos pais de reparar os danos causados por seus filhos. Partindo-se desses fundamentos, busca-se também nova abordagem do instituto do poder familiar, levando em consideração a mudança na concepção das famílias nos últimos anos. O desempenho da autoridade por outras figuras, como os avós e os padrastos, permitem reflexões em torno da responsabilidade sobre os menores que estão sob seus cuidados, principalmente no que pertine ao dever de reparar os danos causados. Acerca do fenômeno da responsabilidade civil, atenta-se para a grande preocupação com a vítima, merecedora de indenização pelos prejuízos sofridos. A possibilidade de atingir o patrimônio de terceiros, independente da caracterização da culpa, sinaliza a garantia dada ao ofendido. A mesma importância merece o interesse do menor, seja no que diz respeito ao seu patrimônio, seja em suas relações existenciais. Em razão disso, o estudo também aborda o ato ilícito cometido por menores, partindo de uma releitura do regime das capacidades, a fim de considerar a análise da conduta culposa do ofensor a partir do seu possível discernimento. Os princípios constitucionais como melhor interesse da criança e do adolescente, dignidade da pessoa humana, solidariedade, igualdade e paternidade responsável figuram como diretrizes à compreensão do tema.

The first molluscan TCTP in Venerupis philippinarum: Molecular cloning and expression analysis

Translationally controlled tumor protein (TCTP) is one of the abundant and ubiquitously expressed proteins in metazoans In the present study, the first molluscan TCTP (denoted as VpTCTP) was identified from Venerupis philippinarum haemocytes by EST and RACE approaches The full-length cDNA of VpTCTP consisted of 1148 nucleotides with an open-reading frame of 555 bp encoding 184 amino acids The deduced amino acid sequence of VpTCTP shared high similarity with TCTPs from other species, indicating that VpTCTP should be a new member of TCTP family Several highly conserved motifs, including 5'terminal ologopyrimidine (5'TOP) starting sequence and rich AU and AUUT elements in 3'UTR, were also identified in VpTCTP The tissue and temporal expression of VpTCTP after Vi boo anguillarum challenge was recorded by quantitative real-time RT-PCR. VpTCTP transcript could be detected in all examined tissues with the highest expression level in haemocytes and the lowest in hepatopancreas Concerning the time-course expression in haemocytes, the relative expression of VpTCTP mRNA was down-regulated sharply from 6 h to 12 h post-infection. Then, the expression level was obviously up-regulated and reached 3.4-fold to that in the control group at 48 h post challenge As time progressed, the expression of VpTCTP recovered to the original level at 96 h. All these results indicated that VpTCTP was an acute-phase protein involved in the Immune response of V philippinarum (C) 2010 Elsevier Ltd. All rights reserved.

A Laminar Cortical Model for 3D Perception of Slanted and Curved Surfaces and of 2D Images: Developement, attention, and Bistability

A model of laminar visual cortical dynamics proposes how 3D boundary and surface representations of slated and curved 3D objects and 2D images arise. The 3D boundary representations emerge from interactions between non-classical horizontal receptive field interactions with intracorticcal and intercortical feedback circuits. Such non-classical interactions contextually disambiguate classical receptive field responses to ambiguous visual cues using cells that are sensitive to angles and disparity gradients with cortical areas V1 and V2. These cells are all variants of bipole grouping cells. Model simulations show how horizontal connections can develop selectively to angles, how slanted surfaces can activate 3D boundary representations that are sensitive to angles and disparity gradients, how 3D filling-in occurs across slanted surfaces, how a 2D Necker cube image can be represented in 3D, and how bistable Necker cuber percepts occur. The model also explains data about slant aftereffects and 3D neon color spreading. It shows how habituative transmitters that help to control developement also help to trigger bistable 3D percepts and slant aftereffects, and how attention can influence which of these percepts is perceived by propogating along some object boundaries.
