Ítem Análisis de los criterios de eficiencia económica y calidad para la determinación de las tarifas del sector eléctrico en Colombia(Universidad EAFIT, 10/10/2005) García Rendón, John Jairo; Cadavid Herrera, José Vicente; Universidad EAFITÍtem Analysis of the regulation and control of privatized home public services in Argentina under the Kirchner period (2003-2015)(Universidad EAFIT, 2021-06) López, Andrea; Universidad de Buenos AiresThis article studies the contractual renegotiations with the privatized companies, providers of electricity, gas, drinking water and basic telephony in the metropolitan area and Greater Buenos Aires (AMBA), as well as their regulatory regime and the evolution of the entities of respective control, during the presidential terms of Néstor Kirchner and Cristina Fernández de Kirchner, in order to analyze the “crossover” or “tension” between the “pro-market” policies promoted from the structural reforms of the 1990s, the original initiatives to change the regulatory institutional framework, the regulations finally approved and the consolidated - and long-standing - practices in the operation of the organizationsdedicated to supervising the functioning of these essential public services. . Under this framework, when analyzing the cycle of design and implementation of regulatory policies, it is noted that those measures that advocated the comprehensive review of contracts and the definition of new regulatory frameworks and control entities were bypassed, generating a greater provision, for internal and external factors, to enter into rate agreements with the concessionaires, without correcting the deficits in state capacity inherited from the previous stage. In this way, the opportunity - as recommended by CEPAL (2011) - to use regulation as a “policy instrument” capable of reversing the asymmetry of power between the State, privatized companies and users is lost.Ítem Ceratocystis cacaofunesta genome analysis reveals a large expansion of extracellular phosphatidylinositol-specific phospholipase-C genes (PI-PLC)(BioMed Central Ltd., 2018-01-17) Molano, E.P.L.; Cabrera, O.G.; Jose, J.; do Nascimento, L.C.; Carazzolle, M.F.; Teixeira, P.J.P.L.; Alvarez, J.C.; Tiburcio, R.A.; Tokimatu Filho, P.M.; de Lima, G.M.A.; Guido, R.V.C.; Corrêa, T.L.R.; Leme, A.F.P.; Mieczkowski, P.; Pereira, G.A.G.; Universidad EAFIT. Departamento de Ciencias; Biodiversidad, Evolución y ConservaciónBackground: The Ceratocystis genus harbors a large number of phytopathogenic fungi that cause xylem parenchyma degradation and vascular destruction on a broad range of economically important plants. Ceratocystis cacaofunesta is a necrotrophic fungus responsible for lethal wilt disease in cacao. The aim of this work is to analyze the genome of C. cacaofunesta through a comparative approach with genomes of other Sordariomycetes in order to better understand the molecular basis of pathogenicity in the Ceratocystis genus. Results: We present an analysis of the C. cacaofunesta genome focusing on secreted proteins that might constitute pathogenicity factors. Comparative genome analyses among five Ceratocystidaceae species and 23 other Sordariomycetes fungi showed a strong reduction in gene content of the Ceratocystis genus. However, some gene families displayed a remarkable expansion, in particular, the Phosphatidylinositol specific phospholipases-C (PI-PLC) family. Also, evolutionary rate calculations suggest that the evolution process of this family was guided by positive selection. Interestingly, among the 82 PI-PLCs genes identified in the C. cacaofunesta genome, 70 genes encoding extracellular PI-PLCs are grouped in eight small scaffolds surrounded by transposon fragments and scars that could be involved in the rapid evolution of the PI-PLC family. Experimental secretome using LC-MS/MS validated 24% (86 proteins) of the total predicted secretome (342 proteins), including four PI-PLCs and other important pathogenicity factors. Conclusion: Analysis of the Ceratocystis cacaofunesta genome provides evidence that PI-PLCs may play a role in pathogenicity. Subsequent functional studies will be aimed at evaluating this hypothesis. The observed genetic arsenals, together with the analysis of the PI-PLC family shown in this work, reveal significant differences in the Ceratocystis genome compared to the classical vascular fungi, Verticillium and Fusarium. Altogether, our analyses provide new insights into the evolution and the molecular basis of plant pathogenicity. © 2018 The Author(s).Ítem Prostitution: what to punish?
