Is it too early to learn lessons from the developed world on the potential of big data technology: Harnessing and nurturing intuition in organisational decision makers
YesAs big data (BD) and data analytics gain significance in Europe, the industry expects that executives will eventually move towards evidence based decision making, and consequently would build sustainable competitive advantages for their organisations. Therefore, the lessons learned from experiences of European executives can be key for human development and also economic development. However, it also seems that in some cases decision makers in Europe seem to not use business intelligence systems at all. Since, executives are intelligent human beings with credible and proven expertise, it seems to raise a question mark on effectiveness of business intelligence systems, and the potential it has in human and economic development. Furthermore, repeated evaluation of literature pointed out that ultimately executives in Europe make decisions by intuition, and this leads to the question whether big data would ever replace intuition. In this paper, the mind-sets of executives about application and limitations of big data have been explored, by taking into account the cognitive factors in decision making. By using this, it is evaluated whether BD technologies can use to accelerate intuition development of the executives, and consequently lead to faster and sustainable economic development in the developing world
Estudio de factibilidad para la implementación de sistemas fotovoltaicos como fuente de energía en el sector industrial de Colombia
El calentamiento global, los gases de efecto invernadero y el deterioro de la calidad de vida del ser humano a causa del impacto generado por la contaminación producida por el sector industrial son problemas que requieren de medidas a corto y mediano plazo para solucionarlos. Entre las soluciones que se han propuesto e implementado durante los últimos 20 años a nivel mundial es la generación de la energía demandada por los sectores residencial, comercial e industrial a partir de fuentes no convencionales y de carácter renovable que contribuyan significativamente con la disminución de emisiones nocivas para el medio ambiente.Tema de Investigación

A study looking at ways to increase acceptance of E-Government systems in Developing Countries: A focus on The Context-System Gap
YesFor developing countries involved in enhancing communication between citizens and public administration and minimizing corruption, it is imperative to exploit information technology. However, certain factors surrounding the context of e-government adoption can either facilitate or hinder the achievement of this objective. In this paper we develop a conceptual framework that aims to enable more successful e-government adoption and aim to expose the factors hindering implementation. Most empirical research and theories on the implementation of e-government in developing countries remain at the macro-level and fail to highlight contextual complexities of deployment and the role of the gap between the citizens and the government. Therefore, this research offers an empirical model differentiating between the electronic context and the electronic system and shed a light over a new gap, government-citizen gap, in the adoption of e-government
Creating a tobacco line with a weaker antifeedant property against colorado potato beetle
Background. Genetic modification of plants is one of the promising strategies to increase their resistance to insect pests. The development of metabolic or RNA interference systems for plant protection requires appropriate models of host-insect interactions. Nicotiana tabacum L. is a classical model plant used in molecular and metabolic engineering. We consider tobacco as a model for developing protective strategies against Colorado potato beetle (Leptinotarsa decemlineata Say, CPB). Normally, tobacco is toxic for CPB due to high content of nicotine and related alkaloids in leaves. Modification of the tobacco genome could provide tobacco genotypes with altered metabolism suitable for CPB feeding. It is known that different mutations in Berberine Bridge-Like (BBL) genes cause different alterations in tobacco leaf alkaloid levels. In the current study, the Cas9/gRNA system targeting members of the BBL gene family of tobacco was used to create a line which can serve as a diet for CPB. Results. In order to obtain tobacco with modified alkaloid content, two gRNAs matching target sequences in six BBL genes were selected. Each gRNA was cloned into a gRNA/Cas9 generic vector. The created constructs were mixed and used for biolistic transformation of tobacco leaf explants together with the pBI121 plasmid harboring the kanamycin resistance gene nptII and the reporter E.coli betaglucuronidase (GUS) gene. Regenerants were selected on 100 mg/l of kanamycin and checked for transgene presence by histochemical GUS-assay. Unexpectedly, the regenerated plants displayed a variety of adverse phenotypic effects including different degree of growth and rooting inhibition, early flowering, increased number of internodes, changes in leaf shape, fusion of flowers, longostyly, and partial sterility. Only one from seven obtained calli produced a population of regenerated plants without severe phenotypic abnormalities. The NtaBBL5-14 line of clonally propagated plants was selected from this population and used for a CPB feeding experiment. It was shown that CPB larvae consume the leaves of NtaBBL5-14 line ten times more efficiently than the leaves of control plants (97±0.5% vs. 9±3% in 24 h respectively). Conclusion. The NtaBBL5-14 tobacco line is suitable for CPB feeding and can be further used as a model for studies in plant-pest interaction. The modification of other genes regulating nicotine metabolism can be a promising strategy to obtain tobacco plants edible for CPB with less pleiotropic effects
Modulating the photoluminescence of bridged silsesquioxanes incorporating Eu(3+)-complexed n,n '-diureido-2,2 '-bipyridine isomers: application for luminescent solar concentrators
Two new urea-bipyridine derived bridged organosilanes (P5 and P6) have been synthesized and their hydrolysis-condensation under nucleophilic catalysis in the presence of Eu(3+) salts led to luminescent bridged silsesquioxanes (M5-Eu and M6-Eu). An important loading of Eu(3+) (up to 11%(w)) can be obtained for the material based on the 6,6'-isomer. Indeed the photoluminescence properties of these materials, that have been investigated in depth (photoluminescence (PL), quantum yield, lifetimes), show a significantly different complexation mode of the Eu(3+) ions for M6-Eu, compared with M4-Eu (obtained from the already-reported 4,4'-isomer) and M5-Eu. Moreover, M6-Eu exhibits the highest absolute emission quantum yield value (0.18 +/- 0.02) among these three materials. The modification of the sol composition upon the addition of a malonamide derivative led to similar luminescent features but with an increased quantum yield (026 +/- 0.03). In addition, M6-Eu can be processed as thin films by spin-coating on glass substrates, leading to plates coated by a thin layer (similar to 54 nm) of Eu(3+)-containing hybrid silica exhibiting one of the highest emission quantum yields reported so far for films of Eu(3+)-containing hybrids (0.34 +/- 0.03) and an interesting potential as new luminescent solar concentrators (LSCs) with an optical conversion efficiency of similar to 4%. The ratio between the light guided to the film edges and the one emitted by the surface of the film was quantified through the mapping of the intensity of the red pixels (in the RGB color model) from a film image. This quantification enabled a more accurate estimation of the transport losses due to the scattering of the emitted light in the film (0.40), thereby correcting the initial optical conversion efficiency to a value of 1.7%.FCT - PTDC/CTM/101324/2008COMPETEFEDE
