Electronic Word Of Mouth On Twitter About Physical Activity In The United States: Exploratory Infodemiology Study, Ni Zhang, Shelly Campo, Kathleen F. Janz, Petya Eckler, Jingzhen Yang, Linda G. Snetselaar, Alessio Signorini

Faculty Research, Scholarly, and Creative Activity

Background:
Twitter is a widely used social medium. However, its application in promoting health behaviors is understudied.
Objective:
In order to provide insights into designing health marketing interventions to promote physical activity on Twitter, this exploratory infodemiology study applied both social cognitive theory and the path model of online word of mouth to examine the distribution of different electronic word of mouth (eWOM) characteristics among personal tweets about physical activity in the United States.
Methods:
This study used 113 keywords to retrieve 1 million public tweets about physical activity in the United States posted between January 1 and March 31, …


Effect Of Fluctuating Temperatures On The Development Of A Forensically Important Blow Fly, Protophormia Terraenovae (Diptera: Calliphoridae), Jodie-A. Warren, Gail S. Anderson Feb 2013

Effect Of Fluctuating Temperatures On The Development Of A Forensically Important Blow Fly, Protophormia Terraenovae (Diptera: Calliphoridae), Jodie-A. Warren, Gail S. Anderson

Faculty Research, Scholarly, and Creative Activity

Experiments were conducted to compare the immature development of Protophormia terraenovae (Robineau-Desvoidy) at fluctuating temperatures of 4-28 and 9-23°C to their mean constant temperature, 16°C. Overall development was fastest at the greater fluctuation and slowest at the constant temperature but showed similar percentages of development time in each stage. The rate summation effect is suspected to have caused this difference in development rate because fluctuations above the mean increase the rate relatively more than temperatures below the mean can lower the rate.
