Hip-hop in Colombia - Essay Example What began as a music practice common among the economically underprivileged groups like the Latinos and the African-Americans transcended into an art form, without national boundaries in a very short time. Hip-hop in Columbia is not only viewed as a simple music form but as a media to express powerful feelings by the youth. The hip-hop music has international reach and the Columbian artists are using it efficiently to underline their plight to the world community through rapping. Hip-Hop appeared in Columbia by late 1980s shortly after the art form had established itself as a distinguished sub-culture in the US. Los Generales R&R, an Afro-Columbian group is reported to be one of the first groups to entertain Columbian music lovers already mesmerized by MC Hammer and NWA. Los Generales broke up shortly after releasing their first CD. But, they were followed by groups like Gotas de Rap and La Etina in the early 1990s paving way for steady growth of Columbian hip-hop. Both the groups were known for expressing their social concerns through their lyrics, and adapting a very independent style which served as an inspiration for the development of later Columbian hip-hop style.

Analysis of a primary research article Example | Topics and Well Written Essays - 250 words

Analysis of a primary research - Article Example The null hypothesis for the second study is the diarrheal outbreak at a day care center was not caused by E. coli O145. In both studies, the independent variables were demographic and environmental characteristics in both settings while the dependent variable was the presence of either of the E. coli strain in stool samples. There was no multivariate analysis or standardization of variables in both studies. The first study is a case control study and the cases were defined as individuals with laboratory confirmed E. coli 0157:H7 or those with a clinically compatible diagnosis (Jay, Garrett and Mohle-Boetan). The cases were healthy individuals. The second study lacks defined cases and controls (Wahl, Vold and Lindstedt 7). The presence of E. coli in both studies was established by culture and typing and the units of measurement for the concentration of the organism were Colony-Forming Units per milliliter (CFU/ML). In both studies, statistics on laboratory diagnosis of the different E. coli strains were presented. Positive culture and typing results were used to support the hypothesis on the presence on an outbreak in both studies. The outbreaks were caused by the E. coli strains in the two studies. Based on the results of the two studies, the authors recommend routine surveillance in an effort to detect future outbreaks. Although no limitations were identified in the first study, the authors in the second study reported limitations in the study design and results. Another limitation in the second study was that the symptoms were self-reported; hence, the study was subject to variations between clinical data and what was reported (Wahl, Vold and Lindstedt 8-9).
