Globalization achievements and challenges for the Vietnamese Seafood Industry
The paper presents main achievements of the Vietnamese seafood industry in the last ten years (1998-2007) - a special period with revolutionary developments, in which seafood processing and export sector has gained breakthroughs in both quantity and quality, motivating the whole industry to take off. From a small and unknown country in the world seafood map, Viet Nam has now become one of the largest seafood producers, ranking third in terms of aquaculture production and sixth in terms of seafood export turnover. Viet Nam's total fisheries production reached 4.16 million MT in 2007, seafood export volume was 950,000MT, at value of US$ 3.76 billion, and 4.2 times higher than that of 1998. The paper also points out challenges and key directions for sustainable development of the Vietnamese seafood industry to the year 2020 in process of further globalization by improvement of its competitiveness and strengthening vertical and horizontal integration.Keywords: Fisheries Economics, Sustainable development, Aquaculture, Globalization, Vietnamese seafood industry, Vertical and horizontal integrationKeywords: Fisheries Economics, Sustainable development, Aquaculture, Globalization, Vietnamese seafood industry, Vertical and horizontal integratio
An End-to-End Time Series Model for Simultaneous Imputation and Forecast
Time series forecasting using historical data has been an interesting and
challenging topic, especially when the data is corrupted by missing values. In
many industrial problem, it is important to learn the inference function
between the auxiliary observations and target variables as it provides
additional knowledge when the data is not fully observed. We develop an
end-to-end time series model that aims to learn the such inference relation and
make a multiple-step ahead forecast. Our framework trains jointly two neural
networks, one to learn the feature-wise correlations and the other for the
modeling of temporal behaviors. Our model is capable of simultaneously imputing
the missing entries and making a multiple-step ahead prediction. The
experiments show good overall performance of our framework over existing
methods in both imputation and forecasting tasks
Influence of Market Type and Time of Purchase on Bacterial Counts and Salmonella and Listeria Prevalence in Whole Chickens in Vietnam
The objective of the current study was to determine the influence of market type and sampling time on Salmonella and Listeria prevalence and bacterial counts of 180 whole chicken carcasses collected from 6 supermarkets (SM), 6 indoor markets (IM), and 6 open markets (OM) in Vietnam, at opening (T0) and 4 h after the opening (T4). Salmonella and Listeria prevalence was at least 25.6% and 42.7%, respectively. Whole birds in IM had greater Salmonella prevalence than birds from both SM and OM by 28.4% and 23.0% (P = 0.006 and 0.022, respectively). Listeria prevalence was lower in whole chickens from SM, at 56.6%, than those in IM and OM (78.6% and 73.2%, P = 0.024 and 0.089, respectively). Whole chicken carcasses had more than 10.1, 7.5, and 9.4 log colony-forming units (CFU)/g of aerobic bacteria, Escherichia coli (E. coli), and coliforms, respectively. Both E. coli and coliform counts were greater in IM than in SM (P = 0.002 and 0.006). However, only E. coli counts differed between SM (7.7 log CFU/g) and OM (8.3 log CFU/g; P = 0.024). These results highlighted high levels of bacteria and high prevalence of Salmonella and Listeria in whole chickens in retail establishments in Vietnam, posing potential food safety and public health risks
