During the past four years, the research of new synthetic methodologies for the rapid construction of enantiomerically pure substituted indole has had a fruitful and important growth. This research line continues to produce stunning arrays of enantioselective technologies either metal or organocatalyzed. Thus, an update of our previous review (Chem. Soc. Rev., 2010, 39, 4449-4465) has become necessary and this critical review documents the literature on this topic, until the end of 2013. © The Royal Society of Chemistry 2015. Source

Although in recent years research in innovation management in retail industries have increased drastically, most of these industries have focused only on addressing consumers' acceptance of the most effective novel systems. For these reasons, a deeper understanding is needed in three main areas: the innovation management approaches in retail industry, the degree of innovation heterogeneity, and the innovation drivers. Starting from these evidences, this paper identifies to what extent there are similarities and differences in the main innovation drivers in retailing if compared to other sectors (i.e. education, game, etc.). © 2014 Elsevier Ltd.

The Ecuadorian Constitution (2008) declared food sovereignty a strategic goal and a government obligation, embracing many of the proposals put forth since the late 1990s by Ecuadorian federations linked to Vía Campesina. The issue of food sovereignty has expanded from the inner circles of peasant organizations to the wider context of the whole Ecuadorian society. The paper provides an overview of this process, describing the collective actions that made it possible. Moreover, it attempts to explain the reasons why the ‘Agrarian Revolution’ is currently evaluated as weak, and the motivations for a gap between constitutional mandates and the ongoing official policies. © 2014 Taylor & Francis.

The increase in the volume and heterogeneity of semistructured data based application scenarios has demanded for next-generation methods that are able to effectively couple syntactic with semantic information in data management and mining tasks. The focus of this paper is on the development of methods for determining semantic relatedness in tree-shaped semistructured data and on the assessment of the impact of these methods on structural sense ranking in such data. By exploiting key features of a lexical knowledge base like WordNet, namely ontological relations and concept definitions, we propose a twofold approach that takes into account the particular form of labeled tree data as a conceptual hierarchical representation of real-world objects. We infer indirect relationships between tag concepts and exploit an interleaved search through different concept hierarchies in order to extend semantic relatedness measures originally conceived for plain-text data to deal with labeled tree data instances. We also develop a structural sense ranking framework which employs a context graph built on the tag concepts and the structural relations among tags in the tree data. Experimental evidence on a large real-world collection of Wikipedia articles has shown that the proposed methods can effectively detect and maximize semantic relatedness in tree-structured data, and can be profitably used to perform structural sense ranking. © 2012 Elsevier Inc.

The numerical models for simulating the seismic response of a frame member are generally classified into two categories according to the nonlinearity distribution in the element: lumped- (LPM) and distributed- (DPM) plasticity models. In the present work, starting from an LPM relating axial load and biaxial bending, a DPM capable of following the evolution of the plastic zone at the ends of a frame member is proposed and implemented in a computer code for the nonlinear analysis of spatial framed structures. Unlike a fibre model (FM), the spread of inelasticity is taken into account by monitoring the inelastic response at the end sections and making assumptions about the curvature distribution in the inelastic zone without discretizing the frame member along its length and over the cross-section. The elastic-plastic solution is obtained by adopting a predictor-corrector iterative procedure based on the Haar-Kàrmàn principle, taking into account the fact that the axis vector of the biaxial bending changes direction along the longitudinal axis of the beam element. Comparisons with a refined FM and a simplified LPM are carried out in order to check the reliability of the DPM. To this end, cantilever steel beams are considered under monotonic (uniaxial) and cyclic (biaxial) bending with different values of the axial force. Afterwards, consideration is given to the nonlinear dynamic response of one-bay single-storey r.c. spatial frames subjected to artificial bi-directional (horizontal) accelerograms matching, on average, EC8 response spectra for a medium subsoil class and low-, medium- and high-risk seismic regions. © 2014 Elsevier Ltd.
