Melanagromyza obtusa (Díptera: Agromyzidae) is recorded for the first time in Colombia. Distribution of this species is mainly Asiatic although it has been recently reported in Florida (The United States of America), the Dominican Republic, Puerto Rico, Haiti, Panama, and Peru. In countries such as India, Indonesia (Java) and Malaysia, it is recognized as an important pest in economic crops of Cajanus cajan (Fabaceae) and, to a lesser degree, in other Fabaceae, such as Flemingia macrophylla.

SARS-CoV-2 is a deadly virus that has affected human life since late 2019. Between all the countries that have reported the cases of patients with SARS-CoV-2 disease (COVID-19), the United States of America has the highest number of infected people and mortality rate. Since different states in the USA reported different numbers of patients and also death cases, analyzing the difference of SARS-CoV-2 between these states has great importance. Since the generated RNA walk from the SARS-CoV-2 genome includes complex random fluctuations that also contain information, in this study, we employ the complexity and information theories to investigate the variations of SARS-CoV-2 genome between different states in the USA for the first time. The results of our analysis showed that the fractal dimension and Shannon entropy of genome walk significantly change between different states. Based on these results, we can conclude that the SARS-CoV-2 genomic structure significantly changes between different states, which is resulted from the virus evolution. Therefore, developing a vaccine for SARS-CoV-2 is very challenging since it should be able to fight various structures of the virus in different states.

INTRODUCTIONThe name, Manie van Rensburg, is virtually unknown in Europe and the United States of America. Recently, some of his work was screened at a South African film festival in Amsterdam at the Kriterion cinema and I had the honour to present a lecture there on 7 October 1995 regarding Van Rensburg and his presence in the cinema. His film work was also highlighted in a small retrospective during October 1996 at the Vrije Universiteit Brussel. IT WAS NOT THE FIRST TIME a Van Rensburg film was screened outside the borders of South Africa. During the 1980s Van Rensburg received an International Film Festival of New York award for his historical TV drama series, Heroes, and a Merit Award from the London Film Festival was given to him for his filmed play, The Native who Caused all the Trouble. His mammoth production, The Fourth...

This paper examined the interface between “racial” and national identity from the perspective of two competing theoretical frameworks: the ideological asymmetry hypothesis and the thesis of Iberian Exceptionalism. In contrast to previous results found in the United States and Israel, use of survey data from Puerto Rico, the Dominican Republic, and Cuba showed some support for both theoretical positions. Consistent with the asymmetry thesis, there was strong and consistent evidence of racial hierarchy within all three Caribbean nations. However, contradicting the asymmetry hypothesis and more in line with the Iberian Exceptionalism perspective, there was a general tendency for all “races” to be equally attached to the nation in both the Dominican Republic and Puerto Rico. Somewhat unexpectedly, Cuban Blacks tended to be slightly more positively attached to the nation than Cuban Whites. These results suggest that the precise interface between racial and national identity will be acutely influenced by the specific socio-political context within each nation.
