Globalization is associated with economic openness and, in this sense, is in line with conservative free market ideology that embraces less government intervention. Globalization is also associated with greater contact with dissimilar outgroups and potential threats from terrorists and seems to run against conservative attitudes toward outgroup threat and civil liberties. We report research employing two nationally representative samples of 1,000 adults (collected in 2006 and 2008) that explored conservative individuals' attitudes as American views of terrorism evolved following 9/11. Despite diminishing estimates of the likelihood of terrorist attacks, conservatism remained strongly associated with support for seeking revenge for foreign terrorist attacks and for restricting the civil liberties of foreign visitors and noncitizens in order to prevent terrorism. These trends were not accounted for by differences in levels of perceived threat or by demographic characteristics distinguishing conservatives from others. Results are discussed in the context of globalization and the role of political ideology. [ABSTRACT FROM AUTHOR]

Objective: To assess the performance of Diagnostic Cost Groups (DCGs) in explaining variation in concurrent utilization for a defined subgroup, patients with substance abuse (SA) disorders, within the Department of Veterans Affairs (VA).Data Sources: A 60 percent random sample of veterans who used health care services during Fiscal Year (FY) 1997 was obtained from VA administrative databases. Patients with SA disorders (13.3 percent) were identified from primary and secondary ICD-9-CM diagnosis codes.Study Design: Concurrent risk adjustment models were fitted and tested using the DCG/HCC model. Three outcome measures were defined: (1) "service days" (the sum of a patient's inpatient and outpatient visit days), (2) mental health/substance abuse (MH/SA) service days, and (3) ambulatory provider encounters. To improve model performance, we ran three DCG/HCC models with additional indicators for patients with SA disorders.Data Collection: To create a single file of veterans who used health care services in FY 1997, we merged records from all VA inpatient and outpatient files.Principal Findings: Adding indicators for patients with mild/moderate SA disorders did not appreciably improve the R-squares for any of the outcome measures. When indicators were added for patients with severe SA who were in the most costly category, the explanatory ability of the models was modestly improved for all three outcomes.Conclusions: Modifying the DCG/HCC model with additional markers for SA modestly improved homogeneity and model prediction. Because considerable variation still remained after modeling, we conclude that health care systems should evaluate "off-the-shelf" risk adjustment systems before applying them to their own populations.
