The microfoundations of territorial disputes: Evidence from a survey experiment in Japan

Although territorial disputes are one of the most fraught issues among states, how public opinion on territorial disputes varies within states and what explains the variation are often overlooked. This paper argues that citizens who prioritize economic considerations are more likely to support compromises over such disputes, while those who prioritize a country’s reputation tend to reject any compromise. Further, the paper hypothesizes that such variation in individual preferences can be explained by proximity to disputed territories. Counterintuitively, residents closer to disputes are more likely to support a compromise than those who live further away, because they are more affected by economic considerations. Those far from the disputed territory can afford to focus on its political aspects, which leads to a more hawkish stance. By using an experimental approach within Japan, this paper examines the validity of the spatial argument, and tests the relative salience of economic and political aspects of territorial disputes. The findings, based on original survey data, show that distance from disputed territories shapes individual preferences, and under some conditions, people living further away from disputed territories are more hawkish

Myocardial viability in patients with ischemic cardiomyopathy-evaluation by 3-D integration of myocardial scintigraphic data--and coronary angiographic data

PURPOSE: To determine the prevalence of viable myocardium in patients with ischemic cardiomyopathy and, to evaluate the value of three-dimensional (3-D) fusion imaging of myocardial scintigraphic and angiographic data to assign coronary artery lesions to the corresponding viable and nonviable myocardial territory. PROCEDURES: In 105 patients, the combination of perfusion and metabolic imaging with (201)thallium ((201)TI) single-photon emission computed tomography (SPECT) and 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG) positron emission tomography (PET) determined viability in dysfunctional myocardium. In addition, the value of 3-D scintigraphic fusion imaging was assessed in these patients. RESULTS: Based on the presence of viable dysfunctional myocardium, 54% of patients with ischemic cardiomyopathy may be considered for coronary revascularization. In 31 of 105 patients, the 3-D fusion imaging was estimated to be helpful in the diagnostic and interpretative process. CONCLUSION: In patients with end-stage coronary artery disease scintigraphic imaging is most important in the decision-making process. Three-dimensional fusion imaging may add important information in approximately 30% of these patients

Chronic inflammation and impaired coronary vasoreactivity in patients with coronary risk factors.

BACKGROUND: The goal of this study was to examine a possible association between systemic microinflammation, as reflected by C-reactive protein (CRP) serum levels, and coronary vasomotion in patients with coronary risk factors but with angiographically normal coronary arteries. METHODS AND RESULTS: Coronary vasomotor function was studied in response to cold pressor testing (CPT) in 71 patients with normal angiograms. In all patients, CPT-induced changes in epicardial luminal area (LA; mm2) were assessed with quantitative angiography. Within 20 days, myocardial blood flow (MBF) responses to CPT were measured (mL x g(-1) x min(-1)) noninvasively with 13N-ammonia and PET imaging. The CPT-induced mean changes in LA and in MBF in patients with elevated CRP (> or =0.5 mg/dL) were significantly impaired compared with patients presenting with CRP levels within normal range (<0.5 mg/dL) (DeltaLA, -1.09+/-0.86 versus 0.45+/-0.63 mm2; DeltaMBF, 0.06+/-0.18 versus 0.44+/-0.31 mL x g(-1) x min(-1); P<0.0001, respectively). Coronary LA changes and MBF responses to CPT were inversely correlated with CRP serum levels (r=-0.84 and r=-0.63; P<0.0001). Lastly, regression analysis revealed a significant correlation between the changes in LA and MBF during CPT for patients with elevated CRP levels and those for patients with normal CRP levels (r=0.56 and r=0.66; P<0.001). CONCLUSIONS: These findings suggest a direct association between systemic microinflammation and altered coronary vasomotor function of both the epicardial conductance and the arteriolar resistance vessels
