Branded Products as a Passport to Global Citizenship: Perspectives from Developed and Developing Countries

Abstract: This article focuses on belief in brands as a passport to global citizenship, defined as a person's perception that global brands create an imagined global identity. The authors assess the effects of this belief on the importance consumers assign to branded products and also examine the antecedent effects of cultural openness and consumer ethnocentrism. Their work focuses on the global youth market in the developing countries of Romania, Ukraine, and Russia and the developed U.S. market. The findings contribute to a broadened understanding of branding in a global marketplace by examining the associations between beliefs about global brands and the importance consumers attach to branded products in their daily lives.

A decade of global volcanic SO 2 emissions measured from space.

Abstract: The global flux of sulfur dioxide (SO2) emitted by passive volcanic degassing is a key parameter that constrains the fluxes of other volcanic gases (including carbon dioxide, CO2) and toxic trace metals (e.g., mercury). It is also a required input for atmospheric chemistry and climate models, since it impacts the tropospheric burden of sulfate aerosol, a major climate-forcing species. Despite its significance, an inventory of passive volcanic degassing is very difficult to produce, due largely to the patchy spatial and temporal coverage of ground-based SO2 measurements. We report here the first volcanic SO2 emissions inventory derived from global, coincident satellite measurements, made by the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite in 2005–2015. The OMI measurements permit estimation of SO2 emissions from over 90 volcanoes, including new constraints on fluxes from Indonesia, Papua New Guinea, the Aleutian Islands, the Kuril Islands and Kamchatka. On average over the past decade, the volcanic SO2 sources consistently detected from space have discharged a total of ~63 kt/day SO2 during passive degassing, or ~23 ± 2 Tg/yr. We find that ~30% of the sources show significant decadal trends in SO2 emissions, with positive trends observed at multiple volcanoes in some regions including Vanuatu, southern Japan, Peru and Chile.
