No full textGoing 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
The Impact of Electrostatic Interactions between Defects on the Characteristics of Random Telegraph Noise
No full textRandom telegraph noise (RTN) is one of the most challenging defect-related reliability concerns in emerging HfO2-based devices due to the higher bulk defect density compared to SiO2. Despite many research efforts, the physical mechanisms determining complex signals (e.g., multilevel, anomalous, temporary RTN) are still unclear and need a deeper investigation. With this driving force, we performed physic-based kinetic Monte Carlo (kMC) simulations in a TiN/HfO2/TiN cell to directly analyze the role of defects which promote RTN, both in steady state and transient regime. The nonmonotonic trends of the ratio of the RTN dwell times with the applied bias frequently found in the literature are found to be caused by changes with the applied voltage of the preferential capture/emission source/destination of traps. The in-depth analysis sheds new light on the conventional methods for defect classification and vertical position estimation. Moreover, such source/destination changes also occur over time due to the dynamics of the local electric field, which varies with the evolution of the surrounding electrostatic landscape. Notably, the local field is given by the overlap of the applied voltage and of the trapped charge contributions, the latter being dominant at low voltages. The analysis of the Markov chains of closely spaced defects shown interdependencies and alterations of the RTN capture and emission times. A new method is proposed to include the impact of electrostatic interactions between defects on RTN
