Universality of peer-influence in social networks


Flávio L. Pinheiro, Marta D. Santos, Francisco C. Santos & Jorge M. Pacheco, Origin of Peer Influence in Social Networks, Physical Review Letters, in press (2014).

Recent empirical studies show that our choices and behaviors not only influence (and are influenced) by our friends but also their friends together with their friends’ friends. This has been coined as “the 3-degrees of influence”, a concept that became extremely popular, spawning ramifications in many of the strategies and procedures that are currently employed in web and social media applications. In a recent manuscript in Physical Review Letters, Pacheco and colleagues resort to different models of information spreading and behavioral dynamics that have been developed in the physical, biological and social sciences, to investigate the origin of peer influence, specifically, whether the patterns one obtains depend on the way information or behavior is spread and on the underlying network of contacts that inter-connects individuals. They show that the resulting patterns are essentially independent of the type of information or behaviors, on how it spreads, and, to a large extent, even of the type of social network that inter-connects individuals. Moreover, they also identify the network features necessary to promote deviations from such “3 degrees of influence” paradigm. The authors demonstrate that in medium to large communities, everybody may ultimately influence and be influenced by almost everybody else. Thus, not only our choices, behaviors and opinions are strongly influenced by a large number of people we have never met, but also our influence on them goes well beyond what one would naively expect.

An updated inventory of the ichthyofauna recorded in Portuguese waters lists up to 230 more species

mar1An updated inventory of the ichthyofauna recorded in Portuguese waters lists up to 230 more species than those listed in Fishbase and previous checklists, consisting in an increase of nearly 30% in the number of fish species recorded in Portuguese territorial waters and the Economic Exclusive Zone (EEZ).

 The grand list includes also the recently proposed extension of the continental platform, making up a total of close to 1200 fish species in an area spanning for 4 227 408 Km2, that corresponds to the total land area occupied by the countries of the European Union. The ichthyofauna present in this region comprises about 88% of the marine fish species recorded for European countries.

These findings were a result of a comprehensive literature search and data mining of fish species records available in Museum collections and major public biodiversity databases. The study was led by the researchers Miguel Carneiro and Rogélia Martins (Instituto Português do Mar e da Atmosfera - IPMA), with the participation of Filipe Costa and Monica Landi from CBMA, Universidade do Minho.

The study was published in the European Journal of Taxonomy and the access is free (http://www.europeanjournaloftaxonomy.eu/index.php/ejt/article/view/196).


Climate policies under wealth inequality

Climate policies under wealth inequality.
Taming the planet's climate requires cooperation. Previous failures to reach consensus in climate summits have been attributed, among other factors, to conflicting policies between rich and poor countries, which disagree on the implementation of mitigation measures. Here we implement wealth inequality in a threshold public goods dilemma of cooperation in which players also face the risk of potential future losses. We consider a population exhibiting an asymmetric distribution of rich and poor players that reflects the present-day status of nations and study the behavioral interplay between rich and poor in time, regarding their willingness to cooperate. Individuals are also allowed to exhibit a variable degree of homophily, which acts to limit those that constitute one's sphere of influence. Under the premises of our model, and in the absence of homophily, comparison between scenarios with wealth inequality and without wealth inequality shows that the former leads to more global cooperation than the latter. Furthermore, we find that the rich generally contribute more than the poor and will often compensate for the lower contribution of the latter. Contributions from the poor, which are crucial to overcome the climate change dilemma, are shown to be very sensitive to homophily, which, if prevalent, can lead to a collapse of their overall contribution. In such cases, however, we also find that obstinate cooperative behavior by a few poor may largely compensate for homophilic behavior.

A cooperação internacional, necessária para combater as alterações climáticas, será conseguida mais facilmente a partir de acordos locais, em vez de basear-se em instituições globais, como as Nações Unidas, segundo um estudo liderado por portugueses. O trabalho desenvolvido por investigadores do Instituto Superior Técnico e da Universidade do Minho, em colaboração com a Princeton University, e publicado no jornal PNAS, concluiu que “as instituições são muito mais estáveis e efetivas quando são locais, quando comparadas com instituições globais, como as Nações Unidas”, no que respeita aos comportamentos relacionados com a mudança do clima.

Future Trends for Recombinant Protein-Based polymers

Future Trends for Recombinant Protein-Based polymers: The Case Study of Development and Application of Silk-Elastin-Like Polymers

Margarida Casal, António M. Cunha, and Raul Machado

Materiacaparedls science and engineering emerged and developed throughout the twentieth century with a primary focus on metals, ceramics and petroleum-based polymers. However, since the 1990s they also expanded to study biological materials, due to the significant progress made in this field. In fact, the recognition of the mechanisms linking nano - and micro-scale structures with macromolecular assembly and organization enable Mmolecular biologists to understand Nature`s refinednways of creating high performance structural materials.
