The objective of this study was to assess the potential of visible and near infrared spectroscopy (VIS+NIRS) combined with multivariate analysis for identifying the geographical origin of cork. The study was carried out on cork planks and natural cork stoppers from the most representative cork-producing areas in the world. Two training sets of international and national cork planks were studied. The first set comprised a total of 479 samples from Morocco, Portugal, and Spain, while the second set comprised a total of 179 samples from the Spanish regions of Andalusia, Catalonia, and Extremadura. A training set of 90 cork stoppers from Andalusia and Catalonia was also studied. Original spectroscopic data were obtained for the transverse sections of the cork planks and for the body and top of the cork stoppers by means of a 6500 Foss-NIRSystems SY II spectrophotometer using a fiber optic probe. Remote reflectance was employed in the wavelength range of 400 to 2500 nm. After analyzing the spectroscopic data, discriminant models were obtained by means of partial least square (PLS) with 70% of the samples. The best models were then validated using 30% of the remaining samples. At least 98% of the international cork plank samples and 95% of the national samples were correctly classified in the calibration and validation stage. The best model for the cork stoppers was obtained for the top of the stoppers, with at least 90% of the samples being correctly classified. The results demonstrate the potential of VIS + NIRS technology as a rapid and accurate method for predicting the geographical origin of cork plank and stoppers

Entre as muitas aplicações das tecnologias de identificação biológica humana, estão as finalidades forenses. O objetivo desta pesquisa foi verificar frequências alélicas de Short Tandem Repeat (STR) e os parâmetros estatísticos de interesse em genética de populações e forense para desenvolver o primeiro banco de dados populacional de DNA na Faculdade de Odontologia de Bauru, Universidade de São Paulo, (FOB/USP) para futuros usos forenses. Frequências alélicas de 15 locos autossômicos e do marcador de gênero amelogenina foram determinadas utilizando amostras de 200 μL de saliva doados por 296 alunos de graduação da FOB/USP, com idade ≥ 18 anos, após aprovação ética. Os testes laboratoriais foram feitos com kits comerciais. Resultados e parâmetros estatísticos foram obtidos por meio de programas clássicos: GeneMapper-ID-X, MS Excel 2002 versão 10.6871.6870, GenAlEx 6.5 e Arlequin 3.5, comparando quatro populações (brasileira, portuguesa, norte-americana e a população deste estudo). Os locos mais polimórficos foram D18S51 (17 alelos) e FGA (15 alelos), seguidos pelo D21S11 (13 alelos) e os menos polimórficos foram D16S539 e TH01 (7 alelos cada). A análise comparativa com amostra da população brasileira proveniente de estudos anteriores (n > 100.000) pelo teste goodness of fit X2 index não mostrou diferenças significativas entre estes grupos (p = 0,9999). Outros parâmetros estatísticos foram calculados comparando as populações: local (deste estudo), portuguesa e norte-americana. A análise de variância molecular (AMOVA) entre as três populações, entre as pessoas da mesma população e para cada pessoa de cada população mostrou que existe uma elevada variância individual (99%), que esta variância é mantida uniformemente entre as pessoas da mesma amostra/região (1%) e entre as três populações estudadas (0%). O estudo confirmou o elevado grau de polimorfismo e a alta heterozigosidade (96,5%) da população. Houve diferença significativa quanto ao gênero (79,7% mulheres) quando comparado à população brasileira em geral (50,4%), explicada pelas características do corpo discente da FOB/USP composto por 80,6% de pessoas do gênero feminino. Interessante foi a observação de uma microvariante alélica no loco D18S51, fora da escada padrão e da escala de abrangência do kit, correspondente ao alelo 29, ainda não definida na base de dados internacional (STRBase, atualizada em 07/08/2015). Esta microvariante deverá ser confirmada por testes familiares e sequenciamento de DNA para verificar a possibilidade de outra ocorrência familiar ou duplicação de nucleotídeos. No futuro, os dados obtidos neste estudo devem ser incorporados ao banco de dados da população brasileira e podem ser considerados como referência genética da população regional, ajudando a elucidar casos forenses. Após a confirmação, a potencial nova microvariante alélica contribuirá para a base de dados internacional STRBase.

In the last few years, one of the lines of research of great interest in the field of emotional intelligence (EI) has been the analysis of the role of emotions in the educational context and, in particular, their influence on learning strategies. The aims of this study are to identify the existence of different EI profiles and to determine possible statistically significant differences in learning strategies between the obtained profiles. The study involved 1253 Chilean school students from 14 to 18 years (M = 15.10, SD = 1.30), who completed the Trait Meta-Mood Scale-24 (TMMS-24) and the Inventory of Learning and Study Strategies—High School version (LASSI-HS). Cluster analysis identified four EI profiles: a group of adolescents with a high EI profile, a group with predominance of low emotional attention and high repair skills, a group with high scores on attention and low scores on clarity and repair, and a final group of adolescents with low EI. Also, students in groups with high overall scores in EI and low attention and high repair emotional obtained higher scores on the different learning strategies; however, the effect size analysis showed that these differences had no empirical relevance.

Following the death of engineer General Jorge Próspero de Verboom in 1744 and after a few years of transition in the management of Spanish fortifications, Juan Martín Zermeño took on the role, initially with a temporary mandate, but then definitively during a second period that ran from 1766 until his death in 1772. He began this second period with a certain amount of concern because of what had taken place during the last period of conflict. The Seven Years War (1756–1763) which had brought Spain into conflict with Portugal and England in the Caribbean had also lead to conflict episodes along the Spanish–Portuguese border. Zermeño’s efforts as a planner and general engineer gave priority to the northern part of the Spanish–Portuguese border. After studying the territory and the existing fortifications on both sides of the border, Zermeño drew up three important projects in 1766. The outposts that needed to be reinforced were located, from north to south, at Puebla de Sanabria, Zamora and Ciudad Rodrigo, which is where he is believed to have come from. This latter township already had a modern installation built immediately after the war of the Spanish Succession and reinforced with the Fort of La Concepción. However, Zamora and Puebla de Sanabria had some obsolete fortifications that needed modernising. Since the middle of the 15th century Puebla de Sanabria had had a modern castle with rounded turrets, that of the counts of benavente. During the 16th and 17th centuries it had also been equipped with a walled enclosure with small bastions. During the war of the Spanish Succession the Portuguese had enlarged the enclosure and had erected a tentative offshoot to the west. In order to draw up the ambitious Puebla de Sanabria project Zermeño had the aid of some previous reports and projects, such as those by the count of robelin in 1722, the one by Antonio de Gaver in 1752, and Pedro Moreau’s report dated June 1755. This study includes a technical analysis of Zermeño’s project and its strategic position within the system of fortifications along the Spanish–Portuguese border.

In the five-year period 2005-09, Brazil has dramatically reduced carbon emissions by around 25% and at the same time has kept a stable economic growth rate of 3.5% annually. This combination of economic growth and emissions reduction is unique in the world. The driver was a dramatic reduction in deforestation in the Amazonian forest and the Cerrado Savannah. This shift empowered the sustainability social forces in Brazil to the point that the national Congress passed (December 2009) a very progressive law internalising carbon constraints and promoting the transition to a low-carbon economy. The transformation in Brazil’s carbon emissions profile and climate policy has increased the potentialities of convergence between the European Union and Brazil. The first part of this paper examines the assumption on which this paper is based, mainly that the trajectory of carbon emissions and climate/energy policies of the G20 powers is much more important than the United Nations multilateral negotiations for assessing the possibility of global transition to a low-carbon economy. The second part analyses Brazil’s position in the global carbon cycle and public policies since 2005, including the progressive shift in 2009 and the contradictory dynamic in 2010-12. The final part analyses the potential for a transition to a low-carbon economy in Brazil and the impact in global climate governance.

This study analyses the current picture and prospects for EU–Brazil relations in the political and security arenas. As actors experiencing relevant changes, albeit in different directions in their respective international status quo, the EU and Brazil have found some common ground for convergence at the macro level on some structural issues, such as the normative framework of a changing global order, the striving for a multipolar world and the relevance and desirability of multilateralism. At the same time, it is argued that they differ significantly as to the strategies pursued in the attainment of those shared interests, resulting in competing, or eventually divergent, policy preferences when addressing specific issues and developments at the international level, limiting the prospects for a deep mutual commitment and engagement in political and security dynamics at the global level.

Whilst shopping malls have been explored at length by critical urban studies, there has been little exploration of their role in restructuring the practice of urban and spatial planning. This article uses the shopping mall as an object of study in the light of the neoliberal trends and post-metropolisation in Southern Europe, with the aim of exploring challenges for urban governance and planning practice and with a focus on the role of the ongoing economic crisis. A threefold exploratory framework – the ‘lost-in-time scenario’, the ‘messianic mall model’ and the ‘(im)mature planning explanation’ – is used to make sense of the local versions of shopping mall development in Lisbon (Portugal) and Palermo (Southern Italy). According to findings, we highlight the clash between the multi-scalar nature of shopping malls and the dominance of the municipal scale in regulatory planning frameworks, and the risk that shopping mall development (at least in Southern Europe) may replicate uneven development patterns, reproducing the pre-conditions of the crisis without helping to overcome it.

The significant gains in export market shares made in a number of vulnerable euro-area crisis countries have not been accompanied by an appropriate improvement in price competitiveness. This paper argues that, under certain conditions, firms consider export activity as a substitute for serving domestic demand. The strength of the link between domestic demand and exports is dependent on capacity constraints. Our econometric model for six euro-area countries suggests domestic demand pressure and capacity-constraint restrictions as additional variables of a properly specified export equation. As an innovation to the literature, we assess the empirical significance through the logistic and the exponential variant of the non-linear smooth transition regression model. We find that domestic demand developments are relevant for the short-run dynamics of exports in particular during more extreme stages of the business cycle. A strong substitutive relationship between domestic and foreign sales can most clearly be found for Spain, Portugal and Italy, providing evidence of the importance of sunk costs and hysteresis in international trade.
