Predictors of review sites usage in hotels

The tourism industry has been strongly impacted by the consumer use of review sites. Since review travel sites such as TripAdvisor allowed accommodations to create own profiles with information, hotels began incorporating these actions into their engaging customers programming. Despite the benefits that review sites can offer to customers, hotels and accommodations, its implementation is not developed and exploited in all its possibilities, and little is known about hotels use of this review sites. This study explores the topic trough quantitative methodology, conducting multiple correlation analysis of data obtained from a sample of 301 hotel managers. Managers consider they are committed to this type of platforms and are capable of use it accurately. Also it was found evidence of correlation between use of TripAdvisor and hotel characteristics (size, ownership structure, and category). Furthermore, multiple regression analysis shows competence and commitment as the most important predictors of use intensity

A Disc Electrophoretic Procedure for Separating Proteins of Marchantia polymorpha: Esterases.

Extracts from Marchanlia polymorpha were used in the development of a disc electrophoretic procedure for the separation of proteins. Dialyzed and fresh extracts were found to produce best resolution when electrophoresed in Tris-Glycine buffer (pH 8.3) and 50 millamps current for 45-60 minutes. The esterase enzyme system was used as an indication of separation. Significantly, 5 bands were detected in induced thalli attesting to the sensitivity and application of this method to developmental studies
