Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Differential efficacy of risperidone versus haloperidol in psychopathological subtypes of subchronic schizophrenia
No full textThe aim of this study was to evaluate the efficacy and tolerability of risperidone versus haloperidol in subchronic schizophrenia, using psychopathological subgroups of patients with negative or positive and mixed symptoms to analyse the possible differential efficacy of the drugs. A total of 33 patients diagnosed using DSM-IV criteria entered the 6 week double-blind study with either risperidone or haloperidol 5 mg/day. Twenty-nine patients completed at least 2 weeks of treatment and entered the last observation carried-forward analysis. Both treatments were effective in reducing total scores and positive and negative subscale scores on the Positive and Negative Scale for Schizophrenia (PANSS), with a significantly better extrapyramidal profile in the risperidone-treated group. When analysis was repeated in each treatment group by psychopathological subtype (negative vs positive-mixed subgroups based on the PANSS composite index), risperidone was significantly superior to haloperidol in the intention to treat analysis in the negative subgroup. Repeated measures multivariate analysis of variance showed a significantly greater improvement in the PANSS negative subscale scores of risperidone-treated patients in the negative subgroup and a significant improvement in the PANSS positive subscale scores in both psychopathological subtypes. Haloperidol was significantly effective only in reducing positive symptoms in the positive subtype. Our results indicate that risperidone may be proposed for first-line treatment of subchronic schizophrenia, in particular the negative subtype. Copyright (C) 2001 John Wiley & Sons, Ltd

Improved decision feedback equalizer using discriminative neural learning
No full textIn this paper we introduce an enhanced Decision
Feedback Equalizer (DFE), based on the use of a
feedforward neural network trained with the
Discriminative Least Squares (DLS) algorithm. The
DFE is a very common architecture in communications
[4] ; its ability to cope with channels characterized by a
high Intersymbol Interference (ISI) comes from the
degree of nonlinearity and the feeback introduced. In
this work we show how Neural Networks can
generalize the DFE, giving superior performance in the
presence of non-minimum phase and non-linear
channels. In this last case, the Neural DFE (NDFE)
outperforms a Viterbi decoder with a decision depth of
five symbols
