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

No full textThe condition of undamaged or lightly damaged internal partitions after seismic events is of utmost importance
for at least three building performance levels: i) life safety, ii) operational and iii) damage. Indeed, victims
may be caused by the weight of falling partitions, the obstruction of the ways out and the dust released by some
(e.g. brick) partitions. Cracks and dislocations of internal partitions, which can be also caused by frequent
earthquakes, may lead to the downtime of the building hosting the partitions; downtime cannot be accepted in
case of strategic buildings and may lead to large losses in case of industrial and commercial buildings. Large
economic losses are also related to the damage itself of the partitions. Consequently, modern seismic codes
pay attention to the protection of these nonstructural elements: i) imposing their seismic qualification; ii)
providing strength verifications, based on accelerations, and displacement verifications, based on story drifts.
Their protection also conditions the structural design: seismic codes link the stiffness of the structure to the
damage of the partitions and the structural strength distribution to the possible irregular distribution of the
partitions.
Contemporaneous architectural choices are leading to a large increase of the use of glass partitions, for both
aesthetic and functional reasons: sound and thermic compartmentations should not be also visual barriers.
Glass partitions are more and more used in offices, belonging also to strategic buildings. On the other hand,
fragility, stiffness and weight of the glass sheets are features increasing the seismic vulnerability of this
partition type. Consequently, the development of glass partitions, remaining operational after strong
earthquakes, is an urgent need, which cannot be reached without a strong cooperation between research and
industry. Indeed, glass partitions are sophisticated industrial products, characterized by a detailed and
expensive manufacture of glass and either steel or aluminum.
The paper shows the development of glass partitions which remain operational after very severe earthquakes,
i.e. under large accelerations and story drifts, as shown by shake table tests. Four types of partitions are
developed, fully glass, glass partition with a glass door, mixed glass and steel and, finally, mixed glass and
wood. It is confirmed that, as already known, simple details may largely increase the seismic performance of
nonstructural element
Vertex-connectivity for node failure identification in Boolean Network Tomography
No full textWe study the node failure identification problem in undirected graphs by means of Boolean Network Tomography. We argue that vertex-connectivity plays a central role. We prove bounds on the maximum number of simultaneous node failures that can be identified in arbitrary networks. We argue that (augmented) grids are a class of networks with large failure identifiability, and provide very tight results in this context
