Title of Dissertation: Three Essays on Internet Platform Usage and Trade
Abstract: In the last decade the key driver of e-commerce growth has been the expansion of internet access. Studies indicate that the internet is transforming both the production and the consumption of goods and services in the domestic and international markets. Internet platform usage has significantly decreased the barriers for firms to communicate with foreign clients and suppliers on their international market participation. Using the internet platform for marketing intelligence enables firms to access information about the external environment at a faster rate and lower cost. The internet has the potential to reduce market-specific fixed entry costs because suppliers can more easily find information about new markets and can also advertise to numerous buyers at once. However, only few studies have studied the linkage between firm’s internet platform usage and its foreign market participation. Thus, this dissertation adds to the limited literature by examining how using the internet platform can affect firm’s participation in global markets.

Title: Evaluation of Treatment Components of a Smoking Cessation
Program for Veterans with Serious Mental Illness
High cigarette smoking rates pose a serious health threat for individuals with serious mental illness (SMI). Despite being as motivated to quit smoking as the general population, quit rates are lower and less research is focused on identifying effective smoking cessation interventions for individuals with SMI. This secondary data analysis examined effectiveness of treatment components within a multifaceted smoking cessation intervention developed for Veterans with SMI (Bennett et al., 2015). The intervention offered five treatment components: (1) group sessions, (2) smoking cessation pharmacotherapy, (3) outreach contacts, (4) medication education sessions, (5) MI sessions. Participants could self-select use and dose of each treatment component. Attending a greater number of group sessions was significantly associated with lower nicotine dependence, greater abstinence self-efficacy, fewer cigarettes smoked per day, and greater likelihood of reporting a reduction in smoking post-intervention. Using a greater number of NRT/medications was significantly associated with lower nicotine dependence, fewer cigarettes smoked per day, greater confidence in quitting smoking, greater likelihood of reporting no smoking in the past week or month, and greater likelihood of reporting plans to quit smoking in the next month. Engaging in a greater number of medication education sessions was significantly associated with fewer cigarettes smoked per day and greater likelihood to report a reduction in smoking post-intervention. Using a greater number of outreach contacts and MI sessions were not associated with any outcomes on smoking measures. Using a greater number of treatment components was associated with significantly lower nicotine dependence, fewer cigarettes smoked per day, and greater intentions to quit smoking in the next month, as compared to using fewer treatment components. Lastly, using a greater number of treatment encounters was associated with significantly lower nicotine dependence, fewer cigarettes smoked per day, and greater smoking reduction, as compared to using fewer treatment encounters. Smokers with SMI can engage in a multicomponent smoking cessation intervention and reduce their smoking. Future studies should explore creative ways to incorporate shared decision-making into smoking cessation intervention development for individuals with SMI.
