Nathaniel Hawthorne is one of the most popular authors of American literature during the 19th century. My research then investigates how Nathaniel Hawthorne's “Alice Doane's Appeal” as well as “The House of Seven Gables” ...
Parent-adolescent relationships, sibling ordinal status, and adolescent adjustment [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Investigating the possible moderating affects of sibling ordinal status, researchers tested how differences in parent-child communication and trust between first-born and later-born children influence adolescent depressed ...
Photoacoustic detection of circulating melanoma cells in the plasma layer of the blood [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
When a melanoma patient is diagnosed, aggressive treatment is advised in an effort to contain the disease. Although the initial malignant cells are destroyed, it is impossible to determine whether or not the cancer has ...
Impact of prior/concurrent exposure to infectious diseases on variability in the 1918-19 flu epidemic on Newfoundland [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Between 1918 and 1920 nearly 2000 people on the island of Newfoundland died from influenza, pneumonia, and related illnesses. Deaths were recorded from all parts of the island, but there is substantial regional variability ...
Efficacy of modified constraint-induced movement therapy (mCIMT) protocol with clients with chronic stroke [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Objective: To determine efficacy of a new modified constraint - induced movement therapy protocol in clients with chronic stroke. Method: Each participant will undergo a six week modified constraint-induced movement (mCIMT) ...
Effect of assumptions by pre-service teachers concerning family life, extracurricular involvement and socioeconomic status [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The state of Missouri wants to produce highly qualified educators in order to facilitate high performing students; because of this it is vital that pre-service teachers alter their expectation in order to maintain high ...
