The Code of Life, Jennifer Doudna, gene editing and the future of the human species by Walter Isaacson
No full textEste es un excelente libro escrito por Walter Isaacson, profesor de historia de la Universidad de Tulane en Estados Unidos. Describe la vida de la investigadora Jennifer Doudna, quien compartió con Emmanuelle Charpentier el Premio Nobel de Química en el 2020 por construir un vector genético que facilita el empleo del sistema CRISPR/Cas9 (siglas que en inglés corresponden a “repeticiones palindrómicas cortas agrupadas y regularmente interespaciadas”), una herramienta empleada en la edición genética. El libro relata que cuando Jennifer estaba en sexto grado en su colegio de la isla de Hilo, archipiélago de Hawái, encontró en su cama La doble hélice, un libro que le había dejado su padre. Al leerlo quedó fascinada por el drama oculto detrás de la competencia para descubrir el ADN, la molécula que contiene el código de la vida. Cuando leyó sobre la gran contribución que la Dra. Rosalind Franklin había hecho con sus fotografías de cristalografía de rayos X, que permitieron descifrar la estructura tridimensional del ADN, Jennifer aprendió que las mujeres también pueden ser científicas. Fue así como decidió hacer una carrera en la ciencia, a pesar de que su asesor en la escuela consideraba que las mujeres no debían hacerlo.COL000096
Being Nixon a man divided
No full text"What was it really like to be Richard Nixon? Evan Thomas tackles this fascinating question by peeling back the layers of a man driven by a poignant mix of optimism and fear. The result is both insightful history and an astonishingly compelling psychological portrait of an anxious introvert who struggled to be a transformative statesman."--Walter Isaacson, author of Steve Job

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
