Introduction to big data and data science: Methods and applications
No full textBig data and data science are transforming our world today in ways we could not have imagined at the beginning of the twenty-first century. The accompanying wave of innovation has sparked advances in healthcare, engineering, business, science, and human perception, among others. In this chapter we discuss big data and data science to establish a context for the state-of-the-art technologies and applications in this book. In addition, to provide a starting point for new researchers, we present an overview of big data management and analytics methods. Finally, we suggest opportunities for future research
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
The dark side of rationality. Does universal moral grammar exist?
No full textOver a century ago, psychoanalysis created an unprecedented challenge: to show that the effects of the unconscious are more powerful than those of consciousness. In an inverted scheme at present time, neurosciences challenge psychoanalysis with experimental and clinical models that are clarifying crucial aspects of the human mind. Freud himself loved to say that psychological facts do not fluctuate in the air and that perhaps one day, biologists and psychoanalysts would give a common explanation for psychic processes. Today, the rapid development of neuroimaging methods has ushered in a new season of research. Crucial questions are becoming more apparent. For instance, how can the brain generate conscious states? Does consciousness only involve limited area of the brain? These are insistent questions in a time where the tendency of neuroscience to naturalize our relationship life is ever more urgent. Consequently, these questions are also pressing: Does morality originate in the brain? Can we still say “being free” or freedom? Why does morality even exist? Lastly, is there a biologically founded universal morality? This paper will try to demonstrate how neurophysiology itself shows the implausibility of a universal morality
The tourist city and the digital restructuring of the urban rent. La città turistica e la ristrutturazione digitale della rendita urbana
No full textQuesto contributo intende sostenere, a partire da analisi qualitative e quantitative,la seguente tesi: la locazione breve turistica è oggi uno dei principali strumentidella rendita e i supporti digitali che la favoriscono ne determinano alcune formee modalità peculiari, in particolar modo nei contesti urbani. L’industria turistica eil capitalismo di piattaforma verranno quindi riletti a partire dal ruolo che svolgo-no nell’ambito dell’economia della renditaGrounded on qualitative and quantitative analyses, this contribution sustains the following thesis: short-term tourist rental (STR) is one of the main tools of urban rent today and the digital supports that promote it determine some of its peculiar conditions, especially in urban contexts. Tourism industry and platform capitalism will therefore be reinterpreted starting from the role they play in the economy of rent
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
