Variations on the Author
No full text“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
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
The Role of the Locus Coeruleus in Cellular and Systems Memory Consolidation
No full textSynaptic plasticity, neuronal replay, and cross-regional communication are considered key physiological processes underlying memory consolidation. Both cellular and systems-level consolidation hypotheses are supported by extensive empirical evidence. However, presently, little is known about the temporal relations between local synaptic modifications and activity dynamics within extended neuronal networks supporting memory. The diffuse ascending neuromodulatory systems, with the locus coeruleus (LC) noradrenergic system being one of them, appear to be ideal candidates for bridging the cellular and systems mechanisms of memory consolidation. According to a canonical view, noradrenaline release from the terminal fields of LC neurons creates a window of heightened synaptic plasticity within a recently activated neuronal network. Importantly, this neuromodulatory input is critical at times of actual learning experience but also functions “off-line,” when experience-activated neuronal ensembles replay and protein-dependent synaptic modifications occur. Tracking the connectivity strength within learning-related large-scale networks combined with monitoring neuromodulatory activity and behavioral assessment of memory appear irreplaceable methodology for examining interactions between cellular and systems mechanisms of memory consolidation, which are both dependent on neuromodulation

No full textLocus coeruleus activity after learning: implication for off-line memory consolidation
No full textBrain networks activated by experience undergo various changes at the molecular, synaptic and systems levels that ultimately lead to stabilization and storage of newly encoded information. According to the consolidation hypothesis, memory formation is a long-lasting process and thus continues after actual learning experience, i.e. off-line. Noradrenaline (NA), a neuromodulator that is released from the terminals of the Locus Coeruleus (LC) neurons, promotes both synaptic strengthening and weakening. It is well established that optimal level of NA-neurotransmission is essential during information encoding and retrieval; however, we only begin to understand the role LC after learning. Earlier studies identified a ~ 2h after post-learning time window when LC-NA influence on memory consolidation is most pronounced; this time window coincides with the protein-dependent phase of synaptic plasticity. At present, the LC firing pattern and the temporal dynamics of LC activity after learning remain largely unexplored. The hippocampal ripples and thalamo-cortical sleep spindles are considered to mediate off-line consolidation. During sleep, LC firing is phase-locked to cortical slow oscillations, NA release promotes cortical activated state when sleep spindles occur. At the same time, LC activity is transiently suppressed around times of ripple/spindle coupling when information transfer is thought to take place. Indeed, experimentally induced phasic LC activation at times of ripples was detrimental for spatial memory. Furthermore, elevated tonic LC firing suppresses generation of both sleep-associated oscillations. Suppression of NA-neurotransmission potentiates thalamocortical oscillations, while suppresses ripple generation. Our new results suggest that reduced NA-neurotransmission may be necessary for generation of a brain state that is favorable for ‘off-line’ inter-regional information transfer. The temporal windows of elevated LC activity during off-line states and the functional significance of LC activation for off-line consolidation remain yet to be discovered
