[en] The coffee market is distinguished for being volatile and uncertain in terms of domestic and international prices. Arabica and Robusta coffee are produced in 23 provinces of Ecuador. A decade-long decline of coffee production prompted the Ecuadorian government to launch a public program for replanting coffee trees towards the end of 2011. A grower’s decision to enter, remain in or exit the coffee sector is based on fluctuating profits from each year’s harvest sale. We analyzed the hypothesis whereby the coffee grower’s decision to leave the sector is explained by volatile and uncertain prices. This paper aimed to evaluate the coffee sector with an application of Real Option Analysis for the period 2002-2012. We also defined entry (H) and exit (L) prices for Arabica and Robusta coffee for the analyzed period. Our findings revealed high H and L prices encourage growers to leave the sector for the most part of the analyzed period. High H and L prices resulted from high variable cost due to increasing wages for farm workers. The Ecuadorian government is developing a policy to help growers make production more efficient, encouraging them to remain in the sector in the long run.
[en] The 600-km segment of the Andean Cordillera in Ecuador includes zones that can be correlated, geologically, with uranium districts elsewhere in the Andes. It is believed that these essentially unexplored zones have the potential for economic uranium mineralization. Exploration activity to date has been limited, although it has involved both geochemical and radiometric techniques to evaluate geological concepts. Minor uranium occurrences (with chemical analyses up to 100 ppm) have been encountered, which provide further incentive to commence large-scale systematic exploration. It is recognized that a very large exploration budget and considerable technical expertise will be required to ensure exploration success. Consequently, participation by groups of proven capability from other countries will be sought for Ecuador's national exploration programme. (author)
[en] Ecuador's YasunI Man and the Biosphere Reserve-located at the intersection of the Amazon, the Andes mountains, and the equator-is home to extraordinary biodiversity and a recently contacted Amazonian indigenous group known as the Waorani (or Huaorani). Relatives of the Waorani, the Tagaeri and Taromenane, still live in voluntary isolation deep in the reserve, with no peaceful contact with the outside world. The YasunI Biosphere Reserve also sits atop large reserves of crude oil, Ecuador's chief export, and contains an abundance of valuable timber species. This volatile combination has led to intense conflicts, and subsequently, increased international interest and concern. To make the issues confronting YasunI more accessible to a growing audience of interested parties, we synthesized information on the biological, social, and political issues of the region, providing a concise overview of its modern history and conservation challenges. We constructed a chronology of key events in the YasunI region over the past century and a series of maps designed to guide readers to a better understanding of the area's complicated array of overlapping designations. Main topics of analysis and discussion include: the Waorani and their ancestors living in voluntary isolation, YasunI National Park, illegal logging, missionary impacts, oil-development-related impacts and conflicts, and the Ecuadorian government's innovative YasunI-ITT Initiative (ITT: Ishpingo-Tiputini-Tambococha).
[en] 'Reference values of thyroid hormones in newborn children' was determined by this research. The work was carried out in two hospitals: Policlinic and Social Security at Riobamba city. The data was compared with international values and healthy adults. It was used 248 samples of umbilical cord blood and 38 samples of vessel blood from adults. The thyroid perfil (T3, T4, TSH and T3, RU) was determined through radioimmunoassay, RIAPC, LOTUS 123 and CHARTMASTER. The following values were obtained in newborn children: T4(ug/dl) = 10,8 + - 3,1 ; T3(ng/dl) = 41,8 + - 26,9; TSH(uUI/ml) 7,2 + - 6,5; <<<<< T3RU() = 22,6 + - 7,9. The data obtained were no significantly different from the international values. If we compare newborns with adults there is a high significant difference; so the values are quite distinct. Since the referencial values found were trusty it was recommended to use them in medical diagnosis
