Fiction. Latin/Latina Studies. In Havana, Cuba, a beautiful young woman rides a bicycle through the city streets to lure men in to her services. Desperate to escape her dead-end life in a city plagued with scarcity, the luscious bicyclist designs a get-rich-quick scheme with a gorgeous John from Canada. A web of deception is weaved and then disastrously unraveled. Daniel Chavarra has long been recognized as one of Latin America's finest writers. Now he again proves why with ADIOS MUCHACHOS, a comic mystery peopled by a delightfully mad band of miscreants, all of them led by a woman you will not soon forget Alicia, the loveliest bicycle whore in all Havana.

Graph representations are pervasive in scientific and social computing. They serve as vital tools to model the interplay between different interacting entities. This monograph delves into the problem of community detection, which is one of the most widely used graph operations toward scientific discovery. Community detection refers to the process of identifying tightly-knit subgroups of vertices in a large graph. These sub-groups (or communities) represent vertices that are tied together through common structure or function. Identification of communities could help in understanding the modular organization of complex networks. However, owing to large data sizes and high computational costs, performing community detection at scale has become increasingly challenging. This monograph presents a detailed review and analysis of some of the leading computational methods and implementations developed for executing community detection on modern day multicore and manycore architectures. The intention is to: a) define the problem of community detection and highlight its scientific significance; b) relate to challenges in parallelizing the operation on modern day architectures; c) provide a detailed report and logical organization of the approaches that have been designed for various architectures; and d) provide insights into the strengths and suitability of different architectures for community detection, and a preview into the future trends of the area. While the focus is on community detection, the challenges, and techniques to overcome the challenges, transcend to several other graph problems that have applications in science and data analytics.

The stories gathered in this anthology reflect the many complex challenges Havana's citizens have had to endure as a result of their country's political isolation - from the hardships of the 'Special Period', to the pitfalls of Cuba's schizophrenic currency system, to the indignities of becoming a cheap tourist destination for well-heeled Westerners. Moving through various moments in its recent history, as well as through different neighbourhoods - from the prefab, Soviet-era maze of Alamar, to the bars and nightclubs of the Malecon and Vedado - these stories also demonstrate the defiance of Havana: surviving decades of economic disappointment with a flair for the comic, the surreal and the fantastical that remains as fresh as the first dreams of revolution.
