We analyzed papers published by researchers from Latin American and from Spain and Portugal (Ibero-America) in the last three years, in the field of public opinion. This study identified topics of interest and principal research techniques. We used qualitative analysis program NVivo11 in the analysis of the findings. As a result, it can be highlighted the predominance of investigation on digital communication, centrally on the digital social network, particularly on Twitter.

Así como los casos de leucemia infantil van en aumento, la tecnología y los tratamientos para enfrentar este cáncer buscan mitigar el impacto de estos efectos secundarios, independientemente del tipo y duración de la quimioterapia como parte del tratamiento, los pacientes pueden presentan efectos secundarios físicos y psicológicos lo que pueden influir en la recuperación del niño.

The purpose of this in vitro study was to compare the adaptation of the cast copings marginal unitary nickel chromium before and after application of the ceramic. The investigation was experimental in vitro. Thirty-two lower premolars were divide in two groups. One group was conducted by the Laboratory Oral Lab S.C.R.L. and the other by Surgical Medical Services VADI S.A.C. The copings and veneering were made following each laboratory standards. The marginal adaptation was measured by a Steromicroscope (Leica Microsystems LAS EZ version 2.0.0, Switzerland) in microns in four zones (mesial, distal, lingual and buccal) before and after application of ceramic. The better marginal adaptation was obtained in group 1A (cap before application of ceramic) with an average of 54.97 μm, while a smaller average marginal adaptation was register in group 1B (cap after application of ceramic) with a m...

This paper analyzes the information treatment of the Mapuche people in the newspaper El Mercurio during two periods. First, between 1950 and 1973 (twentieth century); and second, during the years 2010, 2013 and 2014, (21st century). To this end, a corpus of 340 journalistic texts has been selected, of which 147 correspond to the 20th century (1950-1970) and 193, to the 21st century (2010, 2013-2014). The analysis shows that most of the frames are linked to conflicts, criminal prosecutions and arson attacks; so that El Mercurio prioritizes connotations and negative events to inform about the Mapuche indigenous people.
