Author's Network
Paper Co-Citation Network
Another way to study the database is looking at the relevance that authors have and how they are related to each other. Firstly, let's analyze a network of papers co-citations, that is, the times that two authors appear together referenced in the same paper. So, the following network shows which papers are more times citated and next to which.
Figure 7. The network depicts the times when a paper is citated together with other, within the Scopus minned database. It has been applied a clusterization analysis using the modularity class of the nodes, which is represented by the color of the node and that can be particulary explored with the group selector on the left toolbar of the graph. Also, the size of the nodes are pointing out their medium grade with weights, that is, when a appears more together with others within the network. The graph allows zoom in/out as well as the selection of any word by clicking. Return the graph to its original position by clicking the empty lens. The data was captured and processed with bibliometrix package on R programming and plotted with Gephi Software and Sigma js plugin.
The biggest cluster is the PINK CLUSTER, with 10 members, although it doesn't have the strongest connections. It is a cluster dominated by the texts of Carol Diane Ryff Beyond Ponce de Leon and Life Satisfaction: New Directions in Quest of Successful Ageing (1989) and The Structure of Psychological Well-Being Revisited (1995); together with the references of Richard Ryan On Happiness and Human Potentials: A Review of Research on Hedonic and Eudaimonic Well-Being (2001) and Self-determination theory and the facilitation of intrinsic motivation, social development, and well-being (2000); as well as the articles of Edward Diener Subjective well-being (1984), The Satisfaction With Life Scale (1985), Subjective well-being: Three decades of progress (1999) and New well-being measures: Short scales to assess flourishing and positive and negative feelings (2010).
The ORANGE CLUSTER, with 5 members, hihglights the presence of Martin Seligman, who is the founder of the positive psychology movement. He has the works: Positive psychology: An introduction (2000), Authentic Happiness: Using the New Positive Psychology to Realize Your Potential for Lasting Fulfillment (2002) and Flourish: A Visionary New Understanding of Happiness and Well-being (2011). The first of these books was written with Mihaly Csikszentmihalyi, who also has the article The domain of creativity (1990) present within the cluster. The cluster is completed with the book Character strengths and virtues: A handbook and classification (2004) which Christopher Peterson writes with Martin Seligman
The GREEN CLUSTER includes many works of Corey Lee M. Keyes, which support human flourishing research from a psychological point of view. The references are: Promoting and Protecting Mental Health as Flourishing: A Complementary Strategy for Improving National Mental Health (2007), Optimizing well-being: The empirical encounter of two traditions (2002), Social well-being (1998) and Mental illness and/or mental health? Investigating axioms of the complete state model of health (2005). Together with Keyes and completing the psychological references, there is Barbara Fredrickson with the article written with Losada Positive Affect and the Complex Dynamics of Human Flourishing (2005) as well as the most cited article of the sample, which she writes alone, The role of positive emotions in positive psychology: The broaden-and-build theory of positive emotions (2001).
Finally, the BLUE CLUSTER, just with 4 members, includes the debate about social justice, with the book of Amartya Sen: Development as Freedom (1999), the book of John Rawls, A Theory of Justice (1971) where the author develops an ethical and political theory based on Kant and Hume and alternative to utilitarism; Robert Nozick (1974) Anarchy, State, and Utopia; and Alasdair MacIntyre with After Virtue: A Study in Moral Theory (1981).
