Construction of three new Gateway® expression plasmids for Trypanosoma cruzi

We present here three expression plasmids for Trypanosoma cruzi adapted to the Gateway® recombination cloning system. Two of these plasmids were designed to express trypanosomal proteins fused to a double tag for tandem affinity purification (TAPtag). The TAPtag and Gateway® cassette were introduced into an episomal (pTEX) and an integrative (pTREX) plasmid. Both plasmids were assayed by introducing green fluorescent protein (GFP) by recombination and the integrity of the double-tagged protein was determined by western blotting and immunofluorescence microscopy. The third Gateway adapted vector assayed was the inducible pTcINDEX. When tested with GFP, pTcINDEX-GW showed a good response to tetracycline, being less leaky than its precursor (pTcINDEX).

Time resolved construction of a bimodal laccolith (Torres del Paine, Patagonia)

Granitic and mafic magma pulses were sequentially accreted in the spectacularly exposed shallow crustal Torres del Paine laccolith, in southern Patagonia. This 12.5 Ma pluton forms a composite intrusion with a subvertical feeding system in the west and a laccolith in the east. A key unknown in the formation of sill complexes is how individual magma pulses are assembled over time and the geometry and localization of their feeding system. High resolution zircon CA-ID-TIMS U-Pb dating shows that the laccolith grew first by under-accretion of granitic sills over 90 +/- 30 ka, linked to a `sheet-like' feeding system, followed by underplating of mafic sills after similar to 20 ka of quiescence. In the mafic sills complex, individual sills were injected by over-accretion during 41 +/- 11 ka. Our data show that successive granitic and mafic magmas emplacement generated a volume of similar to 88 km(3) in 162 +/- 11 ka. (C) 2012 Elsevier B.V. All rights reserved.

Norme d'internalité ou biais de confirmation d'hypothèse? Une approche expérimentale de la construction des questionnaires d'internalité

Cette recherche teste l'hypothèse de l'intervention d'un biais de confirmation d'hypothèse dans la procédure actuelle de construction des questionnaires d'internalité. Dans une étude pilote, 18 étudiants ont produit des explications en vue de la construction d'un questionnaire d'internalité soit en ayant connaissance de l'existence d'une norme d'internalité vs d'une norme d'externalité, soit sans activation expérimentale de cette connaissance (condition "contrôle"). Dans une première étude, 32 étudiants ont évalué le lieu de causalité et la plausibilité des explications produites dans l'étude pilote. Dans une seconde étude, 113 étudiants ont évalué la valeur sociale de ces explications internes et externes dans une situation de recrutement. Les résultats indiquent tout d'abord que le biais de confirmation influence les individus lorsqu'ils sont amenés à produire des explications internes et externes. On observe ainsi que la différence en faveur des explications internes sur la plausibilité (étude 1) et sur la valeur sociale (étude 2) est plus marquée en condition "norme d'internalité" qu'en condition "contrôle", et plus dans cette dernière condition que dans la condition "norme d'externalité". De plus, les résultats obtenus dans la condition "contrôle" suggèrent que les explications internes sont plus plausibles (étude 1) et plus valorisées que les explications externes (étude 2). Ainsi, si cette recherche confirme l'impact du biais de confirmation d'hypothèse, elle suggère également l'existence d'une norme d'internalité dans la pensée sociale.

Perspectives on the green construction of the new European Energy Policy

The EU has been one of the main actors involved in the construction process of an international climate change regime, adopting it as an identity sign in the international arena. This activism has reverted in the European political agenda and in the one of its Members States. Therefore, climate change has become a driver for the EU growing participation in energy policy and for its governance evolution. In this context, much attention has been paid to the climate and energy policies integration agreed after the 2007 spring European Council. Apparently, this decision meant a decisive step towards the incorporation of the environmental variable in the energy policy-making. Moreover, the Action Plan [2007-2009] “Energy Policy for Europe” outlined priority actions in a variety of energy-related areas, implying the new European Energy Policy commencement. Against this background, there is still much left to understand about its formulation and its further development. Rooted on the Environmental Policy Integration approach, this paper traces the increasing proximity between environment and energy policies in order to understand the green contribution to the European Energy Policy construction.

Violence and displacement. Evidence from the Spanish civil war (1936-1939)

This paper explores the relationship between violence and displacement during civil war focusing on two different forms of population movements (i.e. incoming and outgoing), and two different forms of violence (i.e. direct and indirect). The paper explores the relationship between displacement and violence at the local level in the context of a civil war fought conventionally using fine-grained data from 1,062 municipalities of the region of Catalonia during the Spanish Civil War (1936-1939). First, the paper suggests that exogenous and endogenous to the war factors combine to generate patterns of resettlement. Second, the evidence indicates that, in acivil war context, refugee flows and violence are interrelated in multiple ways: the arrival of internal refugees in a locality promotes the perpetration of direct violence against civilians; this, in turn, triggers the departure of people from the locality when the other group approaches. Third, indirect violence (i.e. bombings) shows to be the most significant factor accounting for external displacement at the local level, suggesting that bombing can serve as a strong signal for civilians of the type of armed group they are facing. Finally, the Spanish case suggests that the demographic changes provoked by displacement, combined with the lethality of the conflict, are likely to have long-term political consequences.

A three-pronged approach to social business: a Brazilian multi-case analysis

Social businesses present a new paradigm to capitalism, in which private companies, non-profit organizations and civil society create a new type of business with the main objective of solving social problems with financial sustainability and efficiency through market mechanisms. As any new phenomenon, different authors conceptualize social businesses with distinct views. This article aims to present and characterize three different perspectives of social business definitions: the European, the American and that of the emerging countries. Each one of these views was illustrated by a different Brazilian case. We conclude with the idea that all the cases have similar characteristics, but also relevant differences that are more than merely geographical. The perspectives analyzed in this paper provide an analytical framework for understanding the field of social businesses. Moreover, the cases demonstrate that in the Brazilian context the field of social business is under construction and that as such it draws on different conceptual influences to deal with a complex and challenging reality.

Tri-sector partnerships in social entrepreneurship: discourse and practice of the actors from the circles of action and reflection

This article discusses the construction of tri-sector partnerships in three projects conducted in Brazil in different fields of intervention of public policy (access to water, basic education and performance of boards of rights of children and adolescents). Collaborative articulations involving the players from three sectors (the State, civil society and the market) are practices that are little studied in the Brazilian and even in the international context, as tri-sector partnerships are rare, despite the proliferation of lines of discourse in support of alliances between governments and civil society or between companies and NGOs in the management of public policy. As a research strategy, this study resorted to cooperative inquiry, a method that involves breaking down the boundaries between the subjects and the objects of the analysis. Besides working toward a better understanding of the challenges of building tri-sector partnerships in the Brazilian context, the article also tries to show the relevance to public policy studies of investigative methods based on the subjects studied, as a means of developing an understanding of the practices, lines of discourse and dilemmas linked to social action in social programs.

Valoració de l’impacte i repercussió de les drogues de disseny en el medi judicial. Aspectes forenses en els àmbits civil i penal

Les rogues de disseny són utilitzades hores d’ara amb major intensitat encara que no suposen un problema tan greu, a nivell assistencial o clínic, com les drogues més clàssiques. La seva prevalença no ha estat molt estudiada des del punt de vista legal i la seva implicació en procediments civils o penals no és ben coneguda. La recerca pretén obtenir dades del consum de drogues de disseny, avaluar la seva associació amb dades sociodemogràfiques, mèdiques i amb els delictes comesos per la població d’estudi, valorar aspectes forenses, intoxicació i morts degudes al seu consum, revisar sentències i repercussió als àmbits civil i penal en relació amb aquestes drogues, a través de l’estudi d’una mostra de 175 subjectes que es troben detinguts al Jutjat de Guàrdia de Barcelona i de subjectes interns al Centre Penitenciari de Joves de Barcelona.
