In Unbecoming Blackness, Antonio López uncovers an important, otherwise unrecognized century-long archive of literature and performance that reveals Cuban America as a space of overlapping Cuban and African diasporic experiences. López shows how Afro-Cuban writers and performers in the U.S. align Cuban black and mulatto identities, often subsumed in the mixed-race and post-racial Cuban national imaginaries, with the material and symbolic blackness of African Americans and other Afro-Latinas/os. In the works of Alberto O’Farrill, Eusebia Cosme, Rómulo Lachatañeré, and others, Afro-Cubanness articulates the African diasporic experience in ways that deprive negro and mulato configurations of an exclusive link with Cuban nationalism. Instead, what is invoked is an “unbecoming” relationship between Afro-Cubans in the U.S and their domestic black counterparts. The transformations in Cuban racial identity across the hemisphere, represented powerfully in the literary and performance cultures of Afro-Cubans in the U.S., provide the fullest account of a transnational Cuba, one in which the Cuban American emerges as Afro-Cuban-American, and the Latino as Afro-Latino.

Pedestrian Protection Systems (PPSs) are on-board systems aimed at detecting and tracking people in the surroundings of a vehicle in order to avoid potentially dangerous situations. These systems, together with other Advanced Driver Assistance Systems (ADAS) such as lane departure warning or adaptive cruise control, are one of the most promising ways to improve traffic safety. By the use of computer vision, cameras working either in the visible or infra-red spectra have been demonstrated as a reliable sensor to perform this task. Nevertheless, the variability of human’s appearance, not only in terms of clothing and sizes but also as a result of their dynamic shape, makes pedestrians one of the most complex classes even for computer vision. Moreover, the unstructured changing and unpredictable environment in which such on-board systems must work makes detection a difficult task to be carried out with the demanded robustness. In this brief, the state of the art in PPSs is introduced through the review of the most relevant papers of the last decade. A common computational architecture is presented as a framework to organize each method according to its main contribution. More than 300 papers are referenced, most of them addressing pedestrian detection and others corresponding to the descriptors (features), pedestrian models, and learning machines used. In addition, an overview of topics such as real-time aspects, systems benchmarking and future challenges of this research area are presented.

The need to find suitable biomaterials and procedures from alternative sources able to imitate or even enhance the performance of currently used products has become an important focus of research today due to the depletion of non-renewable resources and the increasing concern related to climate change, sustainability and environmental preservation. Thus, this reprint gathers different original articles and review manuscripts from the Special Issue "Development of Bio-Based Materials: Synthesis, Characterization and Applications". The development of partial or fully bio-based materials has been included, with excellent outcomes in many different applications, as well as alternative procedures that can reduce the carbon footprint or optimize both production and energy consumption.
