Outdoor relief by the counties of Missouri
(University of Missouri--Columbia, 1909)
In the following pages the results of a somewhat isolated study of outdoor relief are presented. The general value of the study probably lies in the novel view it affords of a public relief system in the earlier stages of ...
Motivation for smoking and smoking cessation : a self-determination theory investigation
(University of Missouri--Columbia, 2019)
, understanding more about this process may provide important insights into dependence. It appears progress in this area has been slowed by a paucity of appropriate theoretical and methodological tools for research (Stickland & Smith, 2014; 2015). The current...
