El estudio tuvo como objetivo la estimacion, en terminos monetarios del valor economico del agua del humedal, aplicando el metodo de valoracion contingente (MVC), bajo la pregunta de disposicion a pagar por un proyecto que propenda por el cuidado y tratamiento que mejoraria la calidad del agua del lugar mencionado. Durante 4 meses,  se encuestaron a 360 persona que visitaron el humedal. Se concluye que la disponibilidad a pagar (DAP) por las familias visitantes al humedal por la consecucion del proyecto que permitiera el cuidado y tratamiento del  agua del humedal, es significante a un 85%, con entradas que registran hasta los $5000 pesos colombianos por persona. De esta manera el valor economico para la realizacion de este proyecto es altamente rentable.","PeriodicalId":53826,"journal":{"name":"Revista Digital Lampsakos","volume":"1 1","pages":"33-43"},"PeriodicalIF":0.3,"publicationDate":"2016-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68238523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, one way to mitigate the risk is through diversification. However, considering that the portfolio diversification helps to reduce the associated risk, international diversification portfolio provides additional opportunities to reduce risk. This research shows the benefits of international diversification portfolios. For this, investment portfolios formed only with Colombian financial assets, they will diversify with international financial assets such as, Exchange Traded Funds – ETF. We will estimate and compare the Value at Risk of each of the portfolios with traditional methodologies for identifying international financial assets that diversify the portfolios of the Colombian market better. The main finding is that the portfolios with the most liquid shares of the Colombia Stock Exchange decrease the risk when considering ETF that replicate international indices, specifically the S & P 500.","PeriodicalId":53826,"journal":{"name":"Revista Digital Lampsakos","volume":"1 1","pages":"30-42"},"PeriodicalIF":0.3,"publicationDate":"2016-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68238226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This opinion defends that, the necessary quantity of stages and test values to achieve the maximum coverage is too big, what converts the test-case design, and in particular the generation of its values, in a combinatorial problem. That´s why, in many instances, in front of the impossibility of covering all the stages, testers leave out of the design some interesting values, which can discover inconsistencies with the specified requirements. This work presents a proposal for the automatic generation of values of functional test cases, by means of the use of meta-heuristic algorithms and maximizing the coverage of the stages. Furthermore, the algorithms implemented for the generation of initial values and for the generation of combinations are detailed. Additionally a set of good practices to use the component and the comparison of the obtained results with other existing solutions are described.","PeriodicalId":53826,"journal":{"name":"Revista Digital Lampsakos","volume":"1 1","pages":"51-58"},"PeriodicalIF":0.3,"publicationDate":"2016-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68238638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
