Research-to-Practice (R2P) Tools for Improving Safety in Nighttime Highway Construction Work Zones

The safety of workers in nighttime roadway work zones has become a major concern for state transportation agencies due to the increase in the number of work zone fatalities. During the last decade, several studies have focused on the improvement of safety in nighttime roadway work zones; but the element that is still missing is a set of tools for translating the research results into practice. This paper discusses: 1) the importance of translating the research results related to the safety of workers and safety planning of nighttime work zones into practice, and 2) examples of tools that can be used for translating the results of such studies into practice. A tool that can propose safety recommendations in nighttime work zones and a web-based safety training tool for workers are presented in this paper. The tools were created as a component of a five-year research study on the assessment of the safety of nighttime roadway construction. The objectives of both tools are explained as well as their functionalities (i.e., what the tools can do for the users); their components (e.g., knowledge base, database, and interfaces); and their structures (i.e., how the components of the tools are organized to meet the objectives). Evaluations by the proposed users of each tool are also presented.

Student Expositions as an Opportunity to Feel Proud: One Antidote to Expectations of Failure in Zone Schools

Expositions of student work at the end of the extended school year are one of many reform efforts in a specially formed School Improvement Zone in Miami Dade schools. This descriptive analysis offers examples of successful attempts to engender pride even in the face of formidable social and cultural obstacles.

Links across the Gulfstream: The Florida /Bahamas zone, 1780–1900

The links created between Florida and the Bahamas from 1780 to 1900 constituted a major influence in the evolution of a unique society. This dissertation adds to the understanding of this topic by using primary sources and architecture to follow the odyssey of the people who shaped this region. Building on the historiography which examined each area separately, this work focused on the ties forged in the interactions between Florida and the Bahamas. Following the immigrants who shaped Florida and the Bahamas, this work examines cultural holdovers which influenced this region during times of demographic flux. Aesthetic preferences stood out as one way that people maintained connections to their past. The use of architecture as a lens to view this process provides a concrete example of this phenomenon. The societies of Florida and the Bahamas remained intertwined during the late eighteenth and early nineteenth centuries. Forced migrations shaped the trajectory of the evolution of a distinctive culture in these areas bordered by the Gulfstream. This dissertation proves that the links forged between these societies reinforced the patterns which endured throughout the maturation of this area.
