35. Between continuous presents and disruptive futures: Identifying the ideological backbones of global environmental scenarios.

Author

Lauer, Arthur, de Castro, Carlos, and Carpintero, Óscar

Abstract

Despite the great relevance of global environmental scenarios for the study of environmental change and sustainability transitions, they have rarely been the object of analysis for scholars of the social sciences. In this article, we analyze the ideological assumptions of 993 global environmental scenarios contained in 243 academic works. By developing a new categorization of environmental scenarios, we investigate the economic and governance organization reflected in the scenarios, as well as the portrayed human-nature relationships. We find that global environmental scenarios developed and used by the scientific community largely reproduce rather than break with dominant power structures in the economic, governance and cultural domain. The majority of scenarios reflects an anthropocentric worldview and assumes that the logic of global capitalism and of the Westphalian state-based governance system will not change radically during the 21st century. The implicit solution of sustainability problems dominating these scenarios is a combination of continuous economic growth, rapid technological progress and an international (environmental) agreement. 'Alternative scenarios' are scarce, often only problematize one dimension of the social structure of world society and frequently lack explicit drivers of change or pathways to desirable futures. To increase the diversity of scenarios, future research should focus on refining and quantifying existing post-capitalist, post-state-centric and/or ecocentric scenarios, and on developing a range of scenarios whose storyline systematically problematize or even break with current power structures. • We apply a novel categorization of global environmental scenarios to 342 different scenarios. • The great majority of scenarios displays are strong bias toward extending the status quo to the future. • Technological progress and economic growth are presented as solutions to sustainability problems. • Post-capitalist and ecocentric scenarios featuring governance beyond nation states are rare and barely quantified.

Abstract

To link to full-text access for this article, visit this link: http://dx.doi.org/10.1016/j.cose.2009.06.006 Byline: Carlos Javier Hernandez-Castro, Arturo Ribagorda Abstract: We present a black-box attack against an already deployed CAPTCHA that aims to protect a free service delivered using the Internet. This CAPTCHA, referred to as "Math CAPTCHA" or "QRBGS CAPTCHA", requests the user to solve a mathematical problem in order to prove human. We study significant problems both in its design and its implementation, and how those flaws can be used to completely solve this CAPTCHA using a low-cost attack. This attack requires no development in Artificial Intelligence or automatic character recognition, the intended path, thus becoming a side-channel attack, based on the previously mentioned CAPTCHAs flaws. We relate these flaws to common flaws found in other CAPTCHA proposals. We conclude with some tips for enhancing this CAPTCHA that can be considered as general guidelines.
