Success in books: a big data approach to bestsellers
Reading remains the preferred leisure activity for most individuals, continuing to offer a unique path to knowledge and learning. As such, books remain an important cultural product, consumed widely. Yet, while over 3 million books are published each year, very few are read widely and less than 500 make it to the New York Times bestseller lists. And once there, only a handful of authors can command the lists for more than a few weeks. Here we bring a big data approach to book success by investigating the properties and sales trajectories of bestsellers. We find that there are seasonal patterns to book sales with more books being sold during holidays, and even among bestsellers, fiction books sell more copies than nonfiction books. General fiction and biographies make the list more often than any other genre books, and the higher a book˙˙s initial place in the rankings, the longer the book stays on the list as well. Looking at patterns characterizing authors, we find that
fiction writers are more productive than nonfiction writers, commonly achieving bestseller status with multiple books. Additionally, there is no gender disparity among bestselling fiction authors but nonfiction, most bestsellers are written by male authors. Finally we find that there is a universal pattern to book sales. Using this universality we introduce a statistical model to explain the time evolution of sales. This model not only reproduces the entire sales trajectory of a book but also predicts the total number of copies it will sell in its lifetime, based on its early sales numbers. The analysis of the bestseller characteristics and the discovery of the universal nature of sales patterns with its driving forces are crucial for our understanding of the book industry, and more generally, of how we as a society interact with cultural products.

Countries and cities are likely to enter economic activities that are
related to those that are already present in them. Yet, while these path
dependencies are universally acknowledged, we lack an understanding of the
diversification strategies that can optimally balance the development of
related and unrelated activities. Here, we develop algorithms to identify
the activities that are optimal to target at each time step. We find that
the strategies that minimize the total time needed to diversify an economy
target highly connected activities during a narrow and specific time
window. We compare the strategies suggested by our model with the
strategies followed by countries in the diversification of their exports
and research activities, finding that countries follow strategies that are
close to the ones suggested by the model. These findings add to our
understanding of economic diversification and also to our general
understanding of diffusion in networks.

Critical diversity: Divided or united states of social coordination

Much of our knowledge of coordination comes from studies of simple, dyadic systems or systems containing large numbers of components. The huge gap ˙˙in between˙˙ is seldom addressed, empirically or theoretically. We introduce a new paradigm to study the coordination dynamics of such intermediate-sized ensembles with the goal of identifying key mechanisms of interaction. Rhythmic coordination was studied in ensembles of eight people, with differences in movement frequency (˙˙diversity˙˙) manipulated within the ensemble. Quantitative change in diversity led to qualitative changes in coordination, a critical value separating régimes of integration and segregation between groups. Metastable and multifrequency coordination between participants enabled communication across segregated groups within the ensemble, without destroying overall order. These novel findings reveal key factors underlying coordination in ensemble sizes previously considered too complicated or 'messy' for
systematic study and supply future theoretical/computational models with new empirical checkpoints.

Self-Organization and Artificial Life: A Review
Self-organization has been an important concept within a number of disciplines, which Artificial Life (ALife) also has heavily utilized since its inception. The term and its implications, however, are often confusing or misinterpreted. In this work, we provide a mini-review of self-organization and its relationship with ALife, aiming at initiating discussions on this important topic with the interested audience. We first articulate some fundamental aspects of self-organization, outline its usage, and review its applications to ALife within its soft, hard, and wet domains. We also provide perspectives for further research.

Multi-criteria analysis of economic complexity transition in emerging economies: The case of Paraguay

Like many emerging economies, the productive structure of the Paraguayan
economy is not complex. It relies extensively on low value-added
activities in the primary sector such as agriculture and cattle ranching.
These activities have a lower return in terms of economic and social
benefits than other potential productive activities and do not contribute
to increasing capability accumulation. In this paper we present a tool to
support the identification of strategic sectors and products which if
taken advantage of, could leverage development through the accumulation of
productive capabilities. Our guiding question is: Which productive sectors
should be promoted to foster economic development in Paraguay through a
transition towards a more complex economy? To answer this question, we use
concepts from the Economic Complexity theory to identify new products and
cluster them based on the Product Space methodology for the determination
of potential products and combine it with the Analytic Hierarchy Process
(AHP) for multicriteria analysis considering multiple criteria. In doing
so, our proposed methodology contributes to both the Economic Complexity
and the AHP literature. Through this combination, we tackle the
multiplicity of juxtaposed criteria, which should be considered at the
prioritization stage in the crafting of economic restructuring measures
according to the country's capabilities. Our evaluation showed that the
combination of the approaches is useful, and for Paraguay's case, it
helped identify sectors, which, if promoted by policymakers, could help
boost economic development through complexity and capability accumulation.
