Online Network Influences on Emerging Adults’ Alcohol and Drug Use

Researchers have reported that network characteristics are associated with substance use behavior. Considering that social interactions within online networks are increasingly common, we examined the relationship between online network characteristics and substance use in a sample of emerging adults (ages 18–24) from across the United States (N = 2,153; M = 21 years old; 47 % female; 70 % White). We used regression analyses to examine the relationship between online ego network characteristics (i.e., characteristics of individuals directly related to the focal participant plus the relationships shared among individuals within the online network) and alcohol use and substance use, respectively. Alcohol use was associated with network density (i.e., interconnectedness between individuals in a network), total number of peer ties, and a greater proportion of emotionally close ties. In sex-stratified models, density was related to alcohol use for males but not females. Drug use was associated with an increased number of peer ties, and the increased proportion of network members’ discussion and acceptance of drug use, respectively. We also found that online network density and total numbers of ties were associated with more personal drug use for males but not females. Conversely, we noted that social norms were related to increased drug use and this relationship was stronger for females than males. We discuss the implications of our findings for substance use and online network research.     

The fiscal effects of statehood: New Mexico and Arizona, 1903–1919

The residents of US territories often vote against statehood for fear government will use its greater sovereignty to impose a heavier tax burden. On the other hand, public choice theory predicts that fiscal decentralization limits government’s size. The financial reports of New Mexico and Arizona were examined before and after statehood in 1912. Graphical and regression analyses of the ratios of receipts and expenditures to property values and US GNP suggest that the relative price of government rose far more in the two new states than in a control state, Nevada, thus supporting the claims of statehood’s opponents.     

Made in Canada: The evolution of Canadian counter-terrorism policy in the post-9/11 world

Literature on Canada-United States (US) counter-terrorism (CT) cooperation from the early 2000s presumed that Canadian CT policy was driven by US security imperatives and fear, leaving little room for Canada to develop its own path in fighting terrorism. It presumed that: the Canadian government was more worried about the US reaction to terrorism than terrorism itself; Canadian security policy sought to be “separate but cooperative”; and Canadian policy was informed by “wise” understandings of the US. We argue these assumptions no longer hold. Since 2011, with the rise of the Islamic State and foreign fighter activity, the Canadian government took independent steps to address national security concerns in a multilateral environment. We use process tracing to track evolutions in the Passenger Protect Program (Canada's “no-fly list” policy), showing how Canada has increasingly asserted agency in response to violent extremism. It suggests the prior scholarly consensus on the US role in Canadian CT policy must be rethought.
