The main goal of this study is to analyze the degree to which several community elements such as insecurity, discrimination and informal community support might have an influence on the social integration of Latin-American immigrants, a group at risk of social exclusion in Spain. Multivariate linear regression analyses results showed that informal community support is positively related to social integration whereas insecurity is negatively related. The statistical relationship between discrimination and social integration disappears once levels of informal community support are taken into account. A better understanding of the factors that either promote or inhibit the social integration progress of immigrant population is important to orientate public policies and intervention programs that contribute to the adaptation of this population to the host society.

The article questions the degree of importance that has been attributed to insecurity in the recent analysis of Colombia's lack of development in the 19th century, and of the lack of development in post-independence Latin America generally. The author criticizes their lack of empirical evidence, and their lack of comparative focus, both within the hemisphere and outside it, and offers a series of arguments against their conclusions. His own evidence in the Colombian case indicates that neither «anarchy» nor deficiencies in property rights constituted significant brakes on the development of the country's economy. He also questions the direction of causation in institutionalist explanations.
