Much research on acculturation around global experiences has focused on the “type” of overseas experience—e.g. expatriate, repatriate, inpatriate, flexpatriate. The experiences of people in those categories and across various demographics (single/married/divorced; gender; sexual orientation) can differ dramatically. In addition, given the explosion of people working in global business, some global business citizens could well fit into several of those various types of experiences over the course of their careers. In this paper, we propose to push in a somewhat different direction and explore something that for us would be quite new. Rather than focusing on the various categories and their resulting experiences, we take a step back to consider what attributes and ways of thinking a global citizen may need to become better as a global business citizen, regardless of type of experience. The question is less one of “Who am I” than “How can I become better?”. Essentially, we would like to explore what might be required in moving the global citizen from thinking about “global mindset” to “global mindsponge.” When we hear the term mindset, we think of a certain way of thinking that stays rather fixed. So part of the challenge of the paper will be to define and examine what mindsponge might mean in the global context—what does it take to unlearn or squeeze out certain ways of thinking or behaving before absorbing and reshaping new ways of thinking and behaving? Moreover, how might that become part of a natural and regular way of operating, especially in a rapidly changing developing country like Vietnam, in particular? At this early stage, we think of mind sponge as a mechanism that encourages flexibility and receptiveness through a process of using multiple filters and more focus on creativity, or doing things differently to improve an organization or individual performance. Our goal is to develop a basic conceptual framework for “mindsponge,” drawing upon a broad literature review as well as several unstructured interviews, to assess whether the idea of mindsponge helps people perceive that they are more culturally versatile and culturally mobile, regardless of whether they work in or outside of their “home environment.” We hope this would enhance their ability to shape an emerging set of cultural values that erases the divide between “foreign” and “local” cultural differences that so often dominates in emerging economies.

Carbon dioxide (CO2) transfer from inland waters to the atmosphere, known as CO2 evasion, is a component of the global carbon cycle. Global estimates of CO2 evasion have been hampered, however, by the lack of a framework for estimating the inland water surface area and gas transfer velocity and by the absence of a global CO2 database. Here we report regional variations in global inland water surface area, dissolved CO2 and gas transfer velocity. We obtain global CO2 evasion rates of 1.8petagrams of carbon (Pg C) per year from streams and rivers and 0.32Pg Cyr-1 from lakes and reservoirs, where the upper and lower limits are respectively the 5th and 95th confidence interval percentiles. The resulting global evasion rate of 2.1 Pg Cyr-1 is higher than previous estimates owing to a larger stream and river evasion rate. Our analysis predicts global hotspots in stream and river evasion, with about 70 per cent of the flux occurring over just 20 per cent of the land surface. The source of inland water CO2 is still not known with certainty and new studies are needed to research the mechanisms controlling CO2 evasion globally. © 2013 Macmillan Publishers Limited.
