Economics / Ph.D. / This dissertation studies the effect of star power among physicians on the diffusion of a medical technology. Studies of the diffusion of medical technologies document institutional and market level factors influencing diffusion rates and patterns. The role of the physician in the diffusion of medical technology in hospitals is not widely studied. This dissertation seeks to fill this gap. Certain "star" physicians and hospitals are recognized as highly attractive to patients. A star physician is defined as a physician who meets any of the following criteria: (i) completed residency training at top 30 ranked hospital, (ii) graduated from a top 30 medical school or (iii) is included in Castle & Connolly's Top Docs publications. A star hospital is defined as a member of the American Association of Medical Colleges' Council of Teaching Hospitals. Using quarterly data on all bariatric surgeries performed in the state of Pennsylvania from 1995 through 2007, I measure the effect of stars physicians and star hospitals on the diffusion of a surgical innovation in bariatric surgery called laparoscopic gastric bypass surgery. I use logistic and OLS regression to test for effects at both the hospital and physician level. At the hospital level, I find that having a star physician at a hospital raises the likelihood of that hospital diffusing laparoscopic gastric bypass from eleven percent to eighty-nine percent. I find that over the time period from first quarter 2000 to fourth quarter 2001, being a star hospital raises the likelihood of that hospital diffusing laparoscopic gastric bypass from thirteen percent to eighty-seven percent. At the physician level, the empirical results indicate that star physicians exert positive asymmetric influence on the adoption and utilization rates of non-stars at the same hospital. This dissertation supports earlier work in technology diffusion by finding a positive influence from key individuals. It adds to the literature on medical technology diffusion by testing a new data set for a chronic disease treatment. / Temple University--Theses
Emerging and Disruptive Technologies for Education: An Analysis of Planning, Implementation, and Diffusion in Florida's Eleven State University System InstitutionsBradford, Deborah 07 May 2010 (has links)
The purpose of the study was to understand and appreciate the methodologies and procedures used in determining the extent to which an information technology (IT) organization within the eleven member State University Systems (SUS) of Florida planned, implemented, and diffused emerging educational technologies. Key findings found how critical it was that flexibility be given during the planning stages and not rely on standardized models which may or may not be of use any longer. Research also found that the SUS institutions have to be prepared to organize and preserve the deluge of digital data if they intended to remain relevant as a "tower" of knowledge transmissions. The literature found that institutions of higher education needed to keep abreast of the new technologies, new pedagogies, and never before open-access concepts because authors found these ideas were converging and producing an unprecedented period of innovation in learning. Furthermore, the implications of perpetual connectivity to information, peers, and teachers garnered a great deal of attention among educational technologists. However, those implications had not been gauged, especially in Florida's SUS institutions. A survey of those institutions regarding how technologies were planned for, implemented logically, and thoroughly diffused, along with lessons learned could potentially save resources and ensure Florida's institutions continue to be on higher learning's forefront. / Ed.D. / Department of Educational Research, Technology and Leadership / Education / Educational Leadership EdD
Vilka kriterier är viktiga för användarupplevelsen vid interaktion med en språkcafé-robot? / Which criteria are important for the user experience when interacting with a language café robot?Mekonnen, Michael, Tahir, Gara January 2019 (has links)
As the number of immigrants in Sweden rises, the demand for alternative methods for language learning increases simultaneously. The use of social robots for teaching a second language is a promising field. The following research question has been designed to identify how social robots can be improved to better suit second language learners. The research question is: Which criteria are important for the user experience when interacting with a language cafe robot? The main method used to answer the question is Design Thinking with the help of semi-structured interviews. The results were 12 criteria which can be implemented for social robots in the future. The research has also studied how the criteria can be implemented in robots and to what degree the robot Furhat developed by Furhat robotics has implemented the criteria today. / I takt med det stigande antalet immigranter i Sverige ökar efterfrågan på alternativa metoder för språkinlärning. Användningen av sociala robotar för att undervisa andraspråk är ett lovande fält. Följande forskningsfråga har utformats för att identifiera hur sociala robotar kan förbättras för att anpassas till elever som lär sig andraspråk. Forskningsfrågan lyder enligt följande: Vilka kriterier är viktiga för användarupplevelsen när man interagerar med en språkcaférobot? Den huvudsakliga metoden som används för att svara på frågan är Design Thinking med hjälp av semistrukturerade intervjuer. Resultatet var 12 kriterier som kan implementeras för sociala robotar i framtiden. Rapporten har också studerat hur kriterierna kan implementeras i robotar och i vilken grad roboten Furhat som utvecklats av Furhat Robotics har implementerat kriterierna idag.
