Comunicaciones integradas feriales o como planificar con éxito una feria industrial

En este artículo se explica que la feria es una herramienta comercial utilizada habitualmente en el área de Marketing Industrial y que, a pesar de las ventajas que ofrece, recibe diversas críticas. Los frenos a su utilización están muy relacionados con la inversión que suponen tanto en recursos económicos como humanos. En definitiva, la feria es una herramienta con una gran potencialidad pero que requiere de un proceso de planificación riguroso y sistemático, con unos objetivos claros y definidos a partir de la estrategia de marketing global de la empresa. La aplicación del concepto de Comunicaciones Integradas Feriales pretende garantizar al expositor la optimización del esfuerzo realizado, maximizando el valor que las distintas herramientas de Marketing pueden aportar al programa ferial.

ICGE: an R package for detecting relevant clusters and atypical units in gene expression

Background: Gene expression technologies have opened up new ways to diagnose and treat cancer and other diseases. Clustering algorithms are a useful approach with which to analyze genome expression data. They attempt to partition the genes into groups exhibiting similar patterns of variation in expression level. An important problem associated with gene classification is to discern whether the clustering process can find a relevant partition as well as the identification of new genes classes. There are two key aspects to classification: the estimation of the number of clusters, and the decision as to whether a new unit (gene, tumor sample ... ) belongs to one of these previously identified clusters or to a new group. Results: ICGE is a user-friendly R package which provides many functions related to this problem: identify the number of clusters using mixed variables, usually found by applied biomedical researchers; detect whether the data have a cluster structure; identify whether a new unit belongs to one of the pre-identified clusters or to a novel group, and classify new units into the corresponding cluster. The functions in the ICGE package are accompanied by help files and easy examples to facilitate its use. Conclusions: We demonstrate the utility of ICGE by analyzing simulated and real data sets. The results show that ICGE could be very useful to a broad research community.

Problems of industrial fisheries development in the Cross River State

The industrial fisheries as opposed to artisanal fisheries in Cross River State, Nigeria, is discussed, considering the prospect of industrial fisheries in the State and identifying the major fish and shrimp resources within the coastal waters. Industrial fishing was introduced in 1973 when the state government invited a Japaneese company to carry out a joint exploratory shrimp fishing venture. The contributions made by the Seastate Seafoods Company, the Eyib's Nutritional Food and the Arawak Fishing Companies towards the increase in the number of fishing fleet in the state are noted.
