Résultats préliminaires d'un projet de comparaison des deux plus importants répertoires bibliographiques spécialisés en littératures de langue française (accessibles sous forme de bases de données bibliographiques en ligne depuis 2014) : la « Bibliographie de la littérature française » (« Bibliographie der französischen Literaturwissenschaft » ou « KLAPP »), publiée chez Klostermann depuis 1956, et la « Bibliographie de la littérature française » (ou « Rancoeur », précédemment intitulée « Bibliographie de la littérature française), publiée depuis 1953 chez Armand Colin et aux Presses universitaires de France (sous forme de hors-série annuel de la « Revue d'histoire littéraire de la France ») puis chez Classiques Garnier.

El estudio analiza los determinantes de uso y acceso a las tecnologías de información y comunicación en personas de bajos ingresos en pasases como Colombia, México y Perú. El punto central está en analizar las diferencias entre países de acuerdo a diferentes variables socioeconómicas. Se encuentra que la variable que más explica el nivel de acceso digital es la escolaridad. De otro lado no se encuentra una brecha por género sino en Perú. Los resultados también indican que cuando solo se tienen en cuenta las tecnologías más ‘avanzadas’, las diferencias entre la población son más notorias

A set of connections among several nuclear and electronic indexes of reactivity in the framework of the conceptual Density Functional Theory by using an expansion ofthe energy functional in terms of the total number of electrons and the normal coordinates within a canonical ensemble was derived. The relations obtained provided explicit links between important quantities related to the chemical reactivity of a system. This paper particularly demonstrates that the derivative of the electronic energy with respect to the external potential of a system in its equilibrium geometry was equal to the negative of the nuclear repulsion derivative with respect to the external potential

The purpose of this document is to provide a single source of reference for every paper published in the journals directly related to research in Construction Management. It is indexed by author and keyword and contains the titles, authors, abstracts and keywords of every article from the following journals: • Building Research and Information (BRI) • Construction Management and Economics (CME) • Engineering, Construction and Architectural Management (ECAM) • Journal of Construction Procurement (JCP) • Journal of Construction Research (JCR) • Journal of Financial Management in Property and Construction (JFM) • RICS Research Papers (RICS) The index entries give short forms of the bibliographical citations, rather than page numbers, to enable annual updates to the abstracts. Each annual update will carry cumulative indexes, so that only one index needs to be consulted.

There is a family of well-known external clustering validity indexes to measure the degree of compatibility or similarity between two hard partitions of a given data set, including partitions with different numbers of categories. A unified, fully equivalent set-theoretic formulation for an important class of such indexes was derived and extended to the fuzzy domain in a previous work by the author [Campello, R.J.G.B., 2007. A fuzzy extension of the Rand index and other related indexes for clustering and classification assessment. Pattern Recognition Lett., 28, 833-841]. However, the proposed fuzzy set-theoretic formulation is not valid as a general approach for comparing two fuzzy partitions of data. Instead, it is an approach for comparing a fuzzy partition against a hard referential partition of the data into mutually disjoint categories. In this paper, generalized external indexes for comparing two data partitions with overlapping categories are introduced. These indexes can be used as general measures for comparing two partitions of the same data set into overlapping categories. An important issue that is seldom touched in the literature is also addressed in the paper, namely, how to compare two partitions of different subsamples of data. A number of pedagogical examples and three simulation experiments are presented and analyzed in details. A review of recent related work compiled from the literature is also provided.

We suggest the use of a particular Divisia index for measuring welfare losses due to interest rate wedges and in‡ation. Compared to the existing options in the literature: i) when the demands for the monetary assets are known, closed-form solutions for the welfare measures can be obtained at a relatively lower algebraic cost; ii) less demanding integrability conditions allow for the recovery of welfare measures from a larger class of demand systems and; iii) when the demand speci…cations are not known, using an index number entitles the researcher to rank di¤erent vectors of opportunity costs directly from market observations. We use two examples to illustrate the method.

In the past decade, indicators have been created to assess the sustainability performance of companies listed in stock exchange markets. Academics and practitioners expect companies to benefit from being listed in such indexes, but evidence of value creation is still scarce. Since virtually all studies about the Corporate Sustainability Index (ISE) of the S~ ao Paulo Stock Exchange (Brazil) e the object of the present study e focused on the value of shares, we initially looked for answers in the finance theory. We collected secondary data about the financial and economic performance of companies forming the ISE's ‘theoretical portfolio’, as these kinds of indexes are also known. In a second stage, we sought additional motivations for companies to make efforts to be listed in the index. We collected additional data and interviewed representatives of key companies listed in the ISE, as well as industry leaders who chose not to participate in the selection process. The results support the main propositions of the institutional theory, as well as the ‘pays to be green’ literature e that the intangible value created by voluntary environmental initiatives, such as access to knowledge, new capabilities and reputational gain, better explain the efforts companies make to be listed in the ISE index

Seis índices de estresse ambiental foram aplicados a 1.359 dados de 359 vacas Holandesas e 54 vacas Jersey em rebanhos comerciais do Ceará e Rio Grande do Norte. O critério de seleção aplicado aos índices foi sua correlação com a temperatura retal e a freqüência respiratória dos animais. O Índice de Temperatura e Umidade (THI) e o Índice de Globo e Umidade (BGHI) apresentaram os piores resultados, com correlações muito baixas com as respostas dos animais. Os índices escolhidos foram o Índice de Temperatura Equivalente (ESI), correlacionado significativamente com a temperatura retal (r = 0,293) e a freqüência respiratória (r = 0,520), e o Índice de Carga Térmica (HLI), com correlações r = 0,286 e r = 0,542 respectivamente.

OBJETIVOS: propor padrão de normalidade das dimensões do IVventrículo e estudar suas características em neurocisticercose. MÉTODO: em um grupo controle (GC) constituído de 114 indivíduos com tomografias normais e em outro grupo composto de 80 doentes com neurocisticercose (GN), mediram-se a distância fronto-polar de ventrículos laterais (FP) e os diâmetros craniano interno (Cr), ântero-posterior (AP) e látero-lateral (LL) do IVº ventrículo para a padronização de seis índices. RESULTADOS: AP/Cr, AP/LL e AP/FP foram os índices mais discriminatórios e apresentaram, em GC, valores médios de 0,063, 0,267 e 0,582, respectivamente. em GN os valores foram estatisticamente superiores a GC. Selecionaram-se 51 doentes do GN com índice> ou =2 desvios-padrão da média em GC. Neles, AP/Ll foi> ou =1 em 95% doentes com derivação liquórica e em 88% com depressão, ocorrendo em 73% com evolução satisfatória e todos que faleceram. CONCLUSÃO: AP/Cr, AP/LL e, principalmente, AP/FP são representativos das dimensões do IVventrículo.
