"Presenteeism" occurs when an employee goes to work despite a medical illness that will prevent him or her from fully functioning at work. This problem has been well studied in the business and social science literature, and carries increased importance in the health care setting due to the risk of infectious disease transmission in vulnerable patient(More)
PURPOSE The majority of health care, both for acute and chronic conditions, is delivered in the ambulatory setting. Despite repeated proposals for change, the majority of internal medicine residency training still occurs in the inpatient setting. Substantial changes in ambulatory education are needed to correct the current imbalance. To assist educators and(More)
OBJECTIVES To determine whether the survival benefit associated with moderate alcohol use remains after accounting for nontraditional risk factors such as socioeconomic status (SES) and functional limitations. DESIGN Prospective cohort. SETTING The Health and Retirement Study (HRS), a nationally representative study of U.S. adults aged 55 and older. (More)

Hazardous materials are ubiquitous in modern society. The weak link in the safety chain is transportation. Despite the remarkable safety record in the United States, the potential for disaster is real, as has been seen in Mexico, India, and the Soviet Union. Careful planning and cooperation between federal and local governments, industry, and healthcare(More)
This workshop will bring together researchers from the engineering design, engineering learning, and creativity communities to explore emerging theoretical and pedagogical issues related to creativity and cognition in engineering design. The need to produce a creative engineering workforce for the 21st century is well recognized. This workshop will help(More)
America’s economic growth and international competitiveness significantly depend on its ability to innovate. Entrepreneurship is an important pathway to innovation and leadership—however, until recently there has been little research exploring what factors influence whether or not engineering graduates will engage in entrepreneurial activities.

The effect of three accelerators of hemolysis-acetylphenylhydrazine, 9-aminoacridine, and phenothiazone-upon protein and lipid monolayers has been examined. These compounds, in low concentration, cause marked expansion of monolayers of plasma albumin, but have no apparent effect upon cholesterol films. It is suggested that these accelerators may affect the(More)
Engineers of the future are expected to possess a range of competencies in addition to math and science skills. This paper turns to engineering students to explorewhat they think it takes to become a good engineer. Profiles are identified bymeans of a large-scale survey-based investigation of the perceptions of first year engineering students in the US and(More)
