Aureliano Mira Fernandes), eds. L. Saraiva e J. T. Pinto, (Sociedade
Portuguesa de Matematica, Lisboa, 2010) , p.125-145, 2011 In connection to a review of the writings on Galois Theory of the Portuguese mathematician Aureliano Mira Fernandes at turn of the XXth century a brief narrative is presented on how the group theory concepts discovered by Galois are connected to previous work that took centuries to evolve, and how fast they changed the landscape of theoretical and ...

Child &Family Social Work, EarlyView.ABSTRACT Migration entails important changes for families. Despite existing evidence on the process of adaptation, little is known about the degree of social inclusion in a context of high cultural affinity. We examine the variability of social inclusion patterns, indexed by personal, family and social conditions, in 263 Latin American families, with ...

Regularization in the Restricted Four Body Problem [PDF]
Aportaciones Matematicas Memorias de la Sociedad Matematica
Mexicana. Comunicaciones 45 (2012), pp.1-13, 2013 The restricted (equilateral) four-body problem consists of three bodies of masses m1, m2 and m3 (called primaries) lying in a Lagrangian config- uration of the three-body problem, i,e,. they remain fixed at the apices of an equilateral triangle in a rotating coordinate system.

Setting goals for pollinator gardens
Conservation Biology, EarlyView.Abstract In recent years, declines in animal pollinators have stimulated tremendous interest in pollinator‐friendly gardening. There is a widespread notion that pollinator gardens are beneficial, but the specific capacity of pollinator gardens to improve biodiversity conservation and societal well‐being remains unclear.

Invariants and TQFT's for cut cellular surfaces from finite groups [PDF]
Boletim da Sociedade Portuguesa de Matem\'atica, 74 (2016), p. 17, 2015 We introduce the notion of a cut cellular surface (CCS), being a surface with boundary, which is cut in a specified way to be represented in the plane, and is composed of 0-, 1- and 2-cells. We obtain invariants of CCS's under Pachner-like moves on the cellular structure, by counting colourings of the 1-cells with elements of a finite group, subject to

A social network analysis of the European science–policy–society interface on biodiversity
Conservation Biology, EarlyView.Abstract Despite the wealth of evidence on biodiversity status, trends, and policy options in Europe, knowledge often fails to inform policy makers and decision makers effectively. Implementing the EU Biodiversity Strategy for 2030 will require the transformation of engagement and exchange between knowledge providers and policy and decision makers ...

The impact of spanish astrophysics in the 1990's [PDF]
arXiv, 2000 Spanish astronomy has grown rapidly during the 1990s. The number of papers published per year has doubled, to about 4% of the world total. The number of high-impact papers, however, remains constant at about 1% of the world total. Papers from France, Germany and Italy also have lower impact than their numbers suggest, while for the US, UK, Japan ...

African voices and their role in improving north–south collaborations for biodiversity conservation
Conservation Biology, EarlyView.Abstract While the dominance of policies from the Global North has shaped conservation practices, holistic decision‐making is urgently needed to incorporate more local voices, especially in Africa. Effective conservation strategies may be enhanced by incorporating the expertise and resources of the Global North alongside the knowledge, lived ...
