    Property Rights and Intellectual Property Protection, GDP growth and Well-Being in Latin America

    A central argument for increased protections of property rights (PR) is the role they play in encouraging economic transactions, investment and economic growth. Likewise, the utilitarian justification of intellectual property laws is that such rights promote creative inventions and innovation, and thus can make a nation better off. A further argument is psychological: it has also been argued (though rarely tested) that enhanced rights contribute to increases in well-being enjoyed by a county’s citizens. Many Latin American countries have made efforts to improve property rights (and their enforcement) in the recent past, with varying success. Using three data sources (the Latinobarometer, the World Bank, and the World Economic Forum’s Global Competitive Index), this investigation considers the relationship between property rights and intellectual property protection, economic growth, and well-being. The results, which are heterogeneous with respect to labour force status, suggest that policy makers in Latin America should pursue improvements in property rights if they wish to improve citizen well-being while also promoting economic growth

    RĂ©sumĂ© Les caractĂšres Ă©pidĂ©miologiques, cliniques et bactĂ©riologiques des bactĂ©riĂ©mies varient en fonction du service oĂč l'Ă©tude est rĂ©alisĂ©e. Le but de ce travail est d’étudier les caractĂšres Ă©pidĂ©miologiques des bactĂ©riĂ©mies observĂ©es dans un service de Maladies Infectieuses. Nous avons rĂ©alisĂ© une Ă©tude rĂ©trospective qui a portĂ© sur 216 Ă©pisodes bactĂ©riĂ©miques observĂ©s chez 216 patients hospitalisĂ©s dans le service entre janvier 2013 et juin 2014. L'Ăąge moyen de nos malades Ă©tait de 40 ans, une tare prĂ©existante Ă©tait prĂ©sente chez 108patients (50%), dominĂ©e par le diabĂšte (12%), HTA (7%), nĂ©phropathie (5%), l’infection a VIH a Ă©tĂ© retrouvĂ© chez 18% des cas. Une porte d'entrĂ©e Ă©tait identifiĂ©e chez 140 malades (65%). Les portes d'entrĂ©e urinaire et cutanĂ©e Ă©taient les plus frĂ©quentes respectivement dans 48 % et 30 % des Ă©pisodes bactĂ©riĂ©miques. L'origine nosocomiale de la bactĂ©riĂ©mie Ă©tait retenue dans 8% des cas. Les germes les plus frĂ©quemment isolĂ©s Ă©taient les bacilles Ă  Gram nĂ©gatif (54%) au premier rang desquels Escherichia coli suivi de Klebsiella pneumoniae. Les cocci Ă  Gram positif Ă©taient Ă  l'origine de 46 % des bactĂ©riĂ©mies avec prĂ©dominance de Staphylococcus aureus. La mortalitĂ© globale Ă©tait de 15% .La mortalitĂ© Ă©tait de 33% pour la bactĂ©riĂ©mie Ă  Klebsiella pneumoniae

    Spatio-Temporal Characteristics of Global Warming in the Tibetan Plateau during the Last 50 Years Based on a Generalised Temperature Zone - Elevation Model

    Temperature is one of the primary factors influencing the climate and ecosystem, and examining its change and fluctuation could elucidate the formation of novel climate patterns and trends. In this study, we constructed a generalised temperature zone elevation model (GTEM) to assess the trends of climate change and temporal-spatial differences in the Tibetan Plateau (TP) using the annual and monthly mean temperatures from 1961-2010 at 144 meteorological stations in and near the TP. The results showed the following: (1) The TP has undergone robust warming over the study period, and the warming rate was 0.318°C/decade. The warming has accelerated during recent decades, especially in the last 20 years, and the warming has been most significant in the winter months, followed by the spring, autumn and summer seasons. (2) Spatially, the zones that became significantly smaller were the temperature zones of -6°C and -4°C, and these have decreased 499.44 and 454.26 thousand sq km from 1961 to 2010 at average rates of 25.1% and 11.7%, respectively, over every 5-year interval. These quickly shrinking zones were located in the northwestern and central TP. (3) The elevation dependency of climate warming existed in the TP during 1961-2010, but this tendency has gradually been weakening due to more rapid warming at lower elevations than in the middle and upper elevations of the TP during 1991-2010. The higher regions and some low altitude valleys of the TP were the most significantly warming regions under the same categorizing criteria. Experimental evidence shows that the GTEM is an effective method to analyse climate changes in high altitude mountainous regions

    Improved functionalization of oleic acid-coated iron oxide nanoparticles for biomedical applications

    Superparamagnetic iron oxide nanoparticles can providemultiple benefits for biomedical applications in aqueous environments such asmagnetic separation or magnetic resonance imaging. To increase the colloidal stability and allow subsequent reactions, the introduction of hydrophilic functional groups onto the particles’ surface is essential. During this process, the original coating is exchanged by preferably covalently bonded ligands such as trialkoxysilanes. The duration of the silane exchange reaction, which commonly takes more than 24 h, is an important drawback for this approach. In this paper, we present a novel method, which introduces ultrasonication as an energy source to dramatically accelerate this process, resulting in high-quality waterdispersible nanoparticles around 10 nmin size. To prove the generic character, different functional groups were introduced on the surface including polyethylene glycol chains, carboxylic acid, amine, and thiol groups. Their colloidal stability in various aqueous buffer solutions as well as human plasma and serum was investigated to allow implementation in biomedical and sensing applications.status: publishe
