Marcus on Belief and Belief in the Impossible
Full text linkI review but don’t endorse Marcus’ arguments that impossible beliefs are impossible. I defend her claim that belief’s objects are, in some important sense, not the bearers of truth and falsity, discuss her dispositionalism about belief, and argue it’s a good fit with the idea that belief’s objects are Russellian states of affairs.
Reviso, pero no suscribo, los argumentos de Marcus a favor de que las creencias imposibles son imposibles.
Defiendo su tesis de que los objetos de las creencias no son, en algún sentido importante, los soportes
de la verdad y la falsedad; discuto su disposicionalismo acerca de las creencias y argumento que encaja bien
con la idea de que los objetos de las creencias son estados de cosas russellianos

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
Biologically inspired control techniques for compliant reaching /cby R.M. Sunderland.
No full textThis research aims to add to the understanding of manipulation and actuator control with the objective of facilitating the future development of fully autonomous manipulating agents. As a first stage along this path, the work presents a simulated implementation of two techniques designed to control a two degree of freedom arm, equipped with six compliant actuators. After preliminary modelling with a static arm, the first technique, inspired by a biological motor theory called convergent force field control, seeks to use a multi-layer-perceptron (MLP) to steer a custom built dynamic simulation of the arm towards predefined targets within the workspace. The MLP is trained iteratively using mutation hill climbing. The work demonstrates that this approach is capable of creating arm responses that move towards a fixed target from any location within the workspace. That said, the learning approach is not reliable and often gets stuck in local minima. The section concludes by demonstrating the blending of two controllers, to create a smooth range of intermediate results. The second technique combines convergent force field control with another related biological control theory, called equilibrium trajectory control. Key to the success of this technique is the assumption that smooth natural movements of the tip of the arm can be generated by constant rate movement of the arm's equilibrium point, with respect to the workspace. The model proposed uses a form of convergent force field control to guide an internal representation of the equilibrium point towards a target at a constant rate. Various implementation options are considered with particular attention paid to the way the equilibrium point is encoded internally. Initial development of the trajectory generator and length encoder indicate that, for reasonable sizes of MLP, shoulder centred polar encoding is the most computationally efficient scheme. It is hoped that the work presented here will provide a foundation for techniques that will bridge the gap between behaviour based control and low level coordination of complex compliant articulated systems.</p
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
