A design-build workshop organized by Taller CreandoS in Encargos a collective founded by four female architecture professors; Yazmín M. Crespo, AndreaBauzá, Irvis González y Omayra Rivera, at La Perla, a community outside the northern historic city-wall of old San Juan, Puerto Rico. Together the professors share interests to revitalize deteriorated and abandon urban spaces with ephemeral interventions and participative workshops in an effort to redefine the conventional way of understanding the professional practice of architecture. The workshop invited students from the three architecture and design schools in Puerto Rico; Polytechnic University of Puerto Rico, University of Puerto Rico School of Architecture, Pontifical Catholic University of Puerto Rico and the school of Visual Arts in Old San Juan to work together with international architecture collectives Todo porla Praxis from Madrid, Spain; Arquitectura Expandida from Bogotá, Colombia; and FG Studio from New YorkCity in three design-build projects together with the community. The workshop included lectures by the three international architects’ collectives, a design charrette, community presentations, final review, a round table and construction of the interventions from August 31to September 7, 2013.

This article analyses aspects related to the development of the paving, lighting, sewerage and cleaning of streets and squares in the city of San Juan de Puerto Rico, during Miguel de la Torre’s government of the island (1823-1837). With this research we intend to offer a new and complementary view to the existing one on the management of this governor, who, along with the Cabildo, had powers in these matters, while at the same time deepening the analysis of the urban history of the city of San Juan for that period. The information on the experience that other relevant urban centers of the period, such as Madrid, Mexico or Havana, had in this type of actions is also included, with the purpose of contextualizing both the measures applied and their scope.

An overview of the Tren Urbano project in San Juan, Puerto Rico, is presented. Phase 1 will be a 17-km rail rapid transit line from Bayamon to Sagrado Corazon in metropolitan San Juan. The line is standard gauge, third-rail-powered, 750-Vdc, rail rapid transit, fully grade-separated. An initial fleet of 64 cars was ordered, and an option for 10 more has been exercised. The project has been bid as a design-build-operate-maintain effort, with Siemens Transportation Systems, Inc., as the prime contractor. Work has been divided into six segments and bid by local contractors. Through the Systems Turnkey and Test Track contract, Siemens is responsible for all systems elements, including cars, power supply, signals, train control and communications, the yard and shop, and about 2 km of main line with two passenger stations. Systems elements are described, with emphasis on their origin in various countries in addition to the United States. The need for Buy America compliance is mentioned. Some car-borne equipment was designed and initial units were built overseas, with most production being done in U.S. plants owned or contracted by the suppliers. By using international sources, Siemens was able to be the lowest bidder and yet provide a quality system to meet the contract requirements.

Urban ecosystems are a patchwork of habitats that host a broad diversity of animal species. Insects comprise a large portion of urban biodiversity which includes many pest species, including those that transmit pathogens. Mosquitoes (Diptera: Culicidae) inhabit urban environments and rely on sympatric vertebrate species to complete their life cycles, and in this process transmit pathogens to animals and humans. Given that mosquitoes feed upon vertebrates, they can also act as efficient samplers that facilitate detection of vertebrate species that utilize urban ecosystems. In this study, we analyzed DNA extracted from mosquito blood meals collected temporally in multiple neighborhoods of the San Juan Metropolitan Area, Puerto Rico to evaluate the presence of vertebrate fauna. DNA was collected from 604 individual mosquitoes that represented two common urban species, Culex quinquefasciatus (n = 586) and Aedes aegypti (n = 18). Culex quinquefasciatus fed on 17 avian taxa (81.2% of blood meals), seven mammalian taxa (17.9%), and one reptilian taxon (0.85%). Domestic chickens dominated these blood meals both temporally and spatially, and no statistically significant shift from birds to mammals was detected. Aedes aegypti blood meals were from a less diverse group, with two avian taxa (11.1%) and three mammalian taxa (88.9%) identified. The blood meals we identified provided a snapshot of the vertebrate community in the San Juan Metropolitan Area and have potential implications for vector-borne pathogen transmission.
