Which disciplines form digital public health, and how do they relate to each other?: Chen-Chia Pan
No full textA standard public health definition, coined by Acheson in 1998 and adapted by the World Health Organization, describes public health as ‘the art and science of preventing disease, prolonging life and promoting health through the organised efforts of society’. Several other definitions emphasise different foci such as living conditions, the efficient use and equitable distribution of resources, or sustainability. Yet, they all share the dual nature as a science and practice of public health, its focus on the health of entire populations, and its interdisciplinary nature. In particular, joint efforts of individual disciplines are needed to combine subject matter knowledge and approaches to protect and promote population health. Traditional core public health disciplines comprise the social sciences, humanities, natural sciences, and environmental sciences. Their key tasks are summarised in the ten essential public health services, which can be further extended to digital public health. This extension leads to increasing use and integration of technological innovation and advancement into public health functions which require intensive collaborations with disciplines from the engineering field. In this presentation, we aim to describe the transition from public health to digital public health, emphasising the disciplines needed to tackle population health challenges in a digitalised world. In a first step, we will illustrate core disciplines and their sub-disciplines that are traditionally known in the public health field. In a second step, we will introduce further core and sub-disciplines prominent in digital public health. Finally, we will briefly present examples of key strengths and challenges of some of the disciplines. After this presentation, workshop participants should have a first understanding of the role and importance of interdisciplinarity in digital public health. Stefanie Do will host the table on epidemiology during the world coffee
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
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

Full text linkWe 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
