Announcement: 7th Annual Graduate Research Symposium

Join the Greenspun College of Urban Affairs in celebrating graduate students’ research. The Graduate Research Symposium offers opportunities for graduate students from several Urban Affairs academic programs to present their research in an informal environment. Awards will be presented to the top three presenters

Site Controller: A System for Computer-Aided Civil Engineering and Construction

A revolution\0\0\0 in earthmoving, a $100 billion industry, can be achieved with three components: the GPS location system, sensors and computers in bulldozers, and SITE CONTROLLER, a central computer system that maintains design data and directs operations. The first two components are widely available; I built SITE CONTROLLER to complete the triangle and describe it here. SITE CONTROLLER assists civil engineers in the design, estimation, and construction of earthworks, including hazardous waste site remediation. The core of SITE CONTROLLER is a site modelling system that represents existing and prospective terrain shapes, roads, hydrology, etc. Around this core are analysis, simulation, and vehicle control tools. Integrating these modules into one program enables civil engineers and contractors to use a single interface and database throughout the life of a project

Special Project--Feast or Famine: Issues, Problems, and Procedures Relating to Massive Relief Efforts with a Focus on the African Crisis

The profound promise of our era is that for the first time we may have the technical capacity to free mankind from the scourge of hunger. Therefore, today we must proclaim a bold objective--that within a decade no child will go to bed hungry, that no family will fear for its next day\u27s bread, and that no human being\u27s future and capacities will be stunted by malnutrition. One decade later, the ongoing drought and famine in Ethiopia, Chad, Mozambique and other African countries cruelly portray the failure of that promise. Each year, millions of dollars worth of aid, much of it in the form of food, funnels through the international relief system--a network of individuals, corporations, voluntary organizations, governments, and intergovernmental organizations, which disburses relief throughout the world. During the past year, the United States alone has supplied more than 1.5 million tons of agricultural commodities, approximately one-half of the total amount of food given to Africa. For those facing starvation, the provision of food meets an immediate need. But the donation of emergency aid without considering long-term food production requirements of the recipient nation is often an inappropriate response. Starvation in Africa is attributable to conditions that are both natural and man-made, deeply rooted and complex; emergency assistance alone will not remedy a disaster such as this one, engendered not only by drought but by politics and civil strife. To combat the results of such conditions, donors should supplement emergency relief with long-term development assistance

D.I.R.E.C.T. Pathway (Delayed Imaging to Reduce Excessive Computed Tomography) for the Evaluation of Patients with Suspected Renal Colic

Flank pain and the diagnosis of acute renal colic is one of the most common and costly evaluations performed in the emergency department (ED) in the United States. The gold standard for diagnostic imaging of patients who present with flank pain remains non-contrast computed tomography (CT) due to its superior sensitivity and specificity for the identification of urolithiasis when compared to other imaging modalities. Due to concerns regarding radiation exposure, cost, and incidental findings, the relative benefits of alternative imaging modalities for the assessment of suspected renal colic have been evaluated. Ultrasound (US) in particular has been shown to be a safe alternative approach in this clinical scenario. Ultrasound, however, has limitations in defining specific anatomic and stone information needed by urologists to guide clinical management. An US-first, delayed CT approach for the evaluation of patients with suspected renal colic is both feasible and safe. ¾ of enrolled patients received US alone with no missed alternative diagnoses or complications. Nearly 40% of subjects definitively passed a stone and only 10% required surgical intervention. Avoiding upfront CT imaging should be strongly considered in this patient population. The need for confirmatory imaging or clinical follow-up to ensure stone passage remains a question that will require further study and additional long-term data
