Peritoneal mesothelioma: Sonographic findings in nine cases

Ultrasonographic findings in nine cases of peritoneal mesothelioma are presented. The most common findings were sheetlike or nodular peritoneal thickening, soft tissue masses, fixation of the intestinal loops, mesenteric thickening, and minimal ascites which was disproportional to the degree of tumor dissemination. The authors found that abdominal sonography, using 3.75–7.5 MHz transducers, is a useful imaging method for diagnosis of peritoneal mesothelioma in high-risk groups.     

Globalization, R&D and the iPod Cycle

This paper constructs a dynamic scale-free North-South model of trade with endogenous innovation. In the North a local-sourcing-targeted race and an outsourcing-targeted R&D race take place simultaneously within each industry. The former results in the winner firm manufacturing in the North, while the latter culminates in the winner firm's immediate outsourcing to the South, generating the iPod cycle. We study three aspects of globalization: reductions in the resource-requirement in outsourcing-targeted R&D, increased subsidies to outsourced production, and reduced Southern imitation due to TRIPs. Each event boosts outsourcing-targeted R&D and increases the frequency of iPod cycles. The aggregate innovation rate rises despite a possible fall in local-sourcing-targeted R&D, and the North-South relative wage decreases.
