NAFTA Students'Whistle-blowing Perceptions: A Case of Sexual Harassment (La percepción advertidora de Ios alumnos en TLC: un caso de acoso sexual by Peek, L., Roxas, M., Peek, G., Robichaud, Y., Covarrubias, B., Barragán Codina, José Nicolás

“…Sexual harassment is asignificant business risk in terms of financial costs and the loss of reputation. lt is important for corporations to develop sexual harassment policies and to provide mechanisms for employees toreport sexual harassment behaviors to upper level management. This paper reports on business students' responses to a possible Sexual Harassment scenario from Arthur Andersen's Business Ethics Program and the actions that the characters in the video should take in terms of whistle-blowing. l fall 2004,78 students from two U.S. universities and one Mexican and one Canadian university participated in the project as part of the NAFIA Challenges of Accounting and Busrness Sysfems Granf funded by the United States Department of Education Fund for the lmprovement of PostSecondary Education (FIPSE), Human Resources Development Canada (HRDC), and Mexico's Secretaría de Educación Pública (SEP). …”

Polimorfismo de los genes que codifican para las proteínas VP4, VP7 y NSP4 de rotavirus y su asociación con la severidad de la diarrea by González Ochoa, Guadalupe

“…Abstract Of the viruses that cause gastroenteritis, rotavirus is the main causal agent of severe diarrhea; it causes the fence death 440,000 children per year at world-wide level. Some researchers point to proteins VP4, VP7 and NSP4 like pathogenicity factors; VP4 and VP7 are related with the penetration viral into epithelial cells and the synthesis of neutralization antibodies; NSP4 is the first described viral enterotoxin, which, by means of an increase in Ca2+ it triggers the diarrheic processes. …”

Análisis de la expresión genética en la síntesis de acetato de etilo y acetato de isoamilo en Saccharomyces cerevisiae, en distintas condiciones de fermentación en el proceso cerve... by Quintero Vásquez, Gabriela Alejandra

“…These compounds are generated by the activity of certain genes, and although progress has been made in the investigation and it is known that the production of esters is influenced by factors such as strain, wort composition, temperature, pressure, amount of inoculum and dissolved oxygen ; still unknown levels of expression and interaction of these genes in different industrial fermentation conditions.In this paper we determine the level of expression of genes related to the biosynthesis of ethyl acetate and isoamyl acetate in the strains type lager 790 and 820. …”
