Decomposing Revenue Efficiency in Fisheries

Creator:: Alvarez, Antonio and Arias, Carlos
Abstract:: The estimation of production frontiers using revenue as the dependent variable is very common in fisheries research since in multi-species fisheries boats catch several species and their output must be aggregated somehow. The objective of this paper is to decompose revenue efficiency into two components, one due to quantities and...

Monte Carlo analysis of the product handling and high-pressure treatment effects on the Vibrio vulnificus risk to raw oysters consumers

Creator:: Serment-Moreno, Vinicio, Deng, Kai, Wu, Xulei, Su, Yi-Cheng, Fuentes, Claudio, Torres, J. Antonio, and Welti-Chanes, Jorge
Abstract:: A Monte Carlo procedure considering the variability in oyster handling from harvest to raw consumption estimated reductions in the number of Vibrio vulnificus induced septicemia cases achieved by high-pressure processing (HPP). The calculations yielded pathogen load distributions in raw oysters from harvest to consumption. In the warm season, 2-6 min...

Inclusion of the variability of model parameters on shelf-life estimations for low and intermediate moisture vegetables

Creator:: Escobedo-Avellaneda, Zamantha, Velazquez, Gonzalo, Torres, J. Antonio, and Welti-Chanes, Jorge
Abstract:: Shelf-life is the time period during which products retain market-acceptable quality while meeting legal and safety requirements. Deterministic models yield single value estimations of shelf-life typically based on average or worst-case values for input parameters. In deterministic calculations, considering the input parameter variability can be challenging. In this study, a...

Risk Assessment of the Mediterranean Seabass and Seabream industry in Greece: A Stochastic Simulation Approach Based on insurance Claims

Creator:: Theodorou, John A., Kotsonis, Antonios, Sorgeloos, Patrick, Viaene, Jacques, and Tzovenis, Ioannis
Abstract:: The Mediterranean finfish aquaculture is strongly represented from the successful industrial development of the mass production of the Mediterranean seabass (Dicentrarchus labrax) and seabream (Spaurus aurata), with Greece as the major producer country, contributing with approximately 57% of the global farmed production of both species. Despite the difficulty to obtain...

Effects of volcanic and hydrologic processes on forest vegetation: Chaitén Volcano, Chile

Creator:: Swanson, Frederick J., Jones, Julia A., Crisafulli, Charles M., and Lara, Antonio
Abstract:: The 2008-2009 eruption of Chaitén Volcano (Chile) involved a variety of volcanic and associated hydrologic processes that damaged nearby forests. These processes included coarse (gravel) and fine (silt to sand) tephra fall, a laterally directed blast, fluvial deposition of remobilized tephra, a variety of low-temperature mass-movement processes, and a pyroclastic...

Analysis of Vibrio vulnificus Infection Risk When Consuming Depurated Raw Oysters

Creator:: Deng, Kai, Wu, Xulei, Fuentes, Claudio, Su, Yi-Cheng, Welti-Chanes, Jorge, Paredes-Sabja, Daniel, and Torres, J. Antonio
Abstract:: A beta Poisson dose-response model for Vibrio vulnificus food poisoning cases leading to septicemia was used when evaluating the effect of 15°C depuration on the estimated risk of raw oyster consumption. Statistical variability sources included V. vulnificus load at harvest, time and temperature during harvest and transportation to processing plants,...

Reference Points for Vulnerable Fish Species Based on Bioeconomic Age-Structured Models: An Approach for Totoaba macdonaldi

Creator:: Rodríguez-García, Oswaldo Uriel, De Anda-Montañez, Juan Antonio, Valenzuela-Quiñonez, Fausto, Hernández-Flores, Alvaro, Salas-Márquez, Silvia, and María Da-Rocha, José
Abstract:: Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...

On Nonparametric Estimation: With a Focus on Agriculture

Creator:: Färe, Rolf, Grosskopf, Shawna, Pasurka, Carl, and Martins-Filho, Carlos
Abstract:: We review nonparametric estimation of efficiency and productivity, by which we mainly mean activity analysis, or data envelopment analysis (DEA). The review covers topics that we hope will be of special interest to those doing research in the realm of agriculture. We also include a brief appendix addressing nonparametric estimation...

Abstract:: Understanding genetic differentiation and speciation processes in marine species with high dispersal capabilities is challenging. The Chilean dolphin, Cephalorhynchus eutropia, is the only endemic cetacean of Chile and is found in two different coastal habitats: a northern habitat with exposed coastlines, bays and estuaries from Valparaíso (33°02' S) to Chiloé...
