This book is an extended argument about the “coloniality” of power. In a shrinking world where sharp dichotomies, such as East/West and developing/developed, blur and shift, this book points to the inadequacy of current practices in the social sciences and area studies. It explores the crucial notion of “colonial difference” in the study of the modern colonial world and traces the emergence of an epistemic shift, which the book calls “border thinking.” Further, the book expands the horizons of those debates already under way in postcolonial studies of Asia and Africa by dwelling on the genealogy of thoughts of South/Central America, the Caribbean, and Latino/as in the United States. The book's concept of “border gnosis,” or sensing and knowing by dwelling in imperial/colonial borderlands, counters the tendency of occidentalist perspectives to manage, and thus limit, understanding. A new preface discusses this book as a dialogue with Hegel's Philosophy of History.

Abstract Background. The population of Latin America and the Caribbean (LAC) is ageing rapidly, presenting the highest prevalence rates of dementia in the world. In this context, mild cognitive impairment (MCI) is an intermediate condition between normal ageing and dementia. However, very few studies verified the prevalence of MCI in LAC countries; earlier global systematic reviews only considered prevalence reports published in English language. Method. We conducted a systematic review to evaluate the prevalence of MCI in LAC countries and to explore the factors associated with MCI (i.e., age, gender, and education). A database search was conducted in February 2020 using PubMed, Web of Science, Scopus, Lilacs, SciELO, and EMBASE, for population-or community-based studies with MCI data for countries in LAC, published in English, Spanish, or Portuguese language. From k=2,168 identified and k=1,684 screened studies, only articles were selected that included subjects with a precise diagnosis of MCI. The studies were qualitatively assessed using the JBI critical appraisal checklist for studies reporting prevalence data tool. Results. A total of nine studies met the criteria, published between 2007 and 2019, including a total of 17,812 participants in nine countries Brazil, Mexico, Argentina, Colombia, Peru, Cuba, Dominican Republic, Venezuela, and Costa Rica. Estimates for MCI prevalence ranged from 1.2% to 34%, with most estimates between 1.2% and 6.45%. Estimates differed by age group, gender, and educational level. Discussion. This is the first systematic review of the prevalence of MCI in LAC countries, considering only high-quality studies adopting rigorous diagnostic criteria.

Many coral reefs in the Caribbean, and elsewhere, have undergone changes from hard coral to fleshy algal dominance over the past two decades which has often been interpreted as a localized response to eutrophication and fishing. Here, data on the abundance of hard corals and algae from lagoonal patch reefs distributed throughout a large (260 km2) remote reef atoll located approximately 30 km offshore from the sparsely-populated coast of Belize, Central America, are compared with a study of these patch reefs conducted 25 years previously. Data and observations indicate that these patch reefs have undergone a major change in their ecology associated with a 75% reduction in total hard coral, a 99% loss in the cover of Acropora cervicornis and A. palmata, and a 315% increase in algae, which are mostly erect brown algae species in the genera Lobophora, Dictyota, Turbinaria and Sargassum. Such changes have been reported from other Caribbean reefs during the 1980s, but not on such a remote reef and the present changes may be attributed primarily to both a disease that began killing Acropora in this region in the mid 1980s and a reduction in herbivory. The low level of herbivory may be attributable to the disease-induced loss of the sea urchin Diadema antillarum in 1983, or fishing of herbivorous fishes, but both explanations are speculative. The present density of fisherfolk is low, and their efforts are not targetted at herbivorous fishes, and population densities of D. antillarum 14 years after the mortality are <1 individual per 1000 m2, but there is no comparative data from before the die off. There is, however, no indication that these major changes occurred on the fore reef, because A. palmata is abundant and erect algal abundance is low. We suggest that reported changes in other Caribbean reefs are not necessarily or exclusively influenced by local human factors such as localized intense eutrophication or fishing.
