Utopia, A Must: A Review Essay on Benjamin Kunkel’s Utopia or Bust

Utopia or Bust, more than many foundational alternatives, forcefully though with non-sectarian wisdom, re-implants the notion of utopia to the front-of-the-line of Left theory (whether economic, geographic, political, social, and/or cultural). Kunkel's introductory survey reminds us through Harvey, among others, that “Utopia exists and that other systems, other spaces, are still possible."

Global compilation of benthic data sets I

Approaches to quantify the organic carbon accumulation on a global scale generally do not consider the small-scale variability of sedimentary and oceanographic boundary conditions along continental margins. In this study, we present a new approach to regionalize the total organic carbon (TOC) content in surface sediments (<5 cm sediment depth). It is based on a compilation of more than 5500 single measurements from various sources. Global TOC distribution was determined by the application of a combined qualitative and quantitative-geostatistical method. Overall, 33 benthic TOC-based provinces were defined and used to process the global distribution pattern of the TOC content in surface sediments in a 1°x1° grid resolution. Regional dependencies of data points within each single province are expressed by modeled semi-variograms. Measured and estimated TOC values show good correlation, emphasizing the reasonable applicability of the method. The accumulation of organic carbon in marine surface sediments is a key parameter in the control of mineralization processes and the material exchange between the sediment and the ocean water. Our approach will help to improve global budgets of nutrient and carbon cycles.

Metafísica do tempo presente: sobre o programa de Walter Benjamin a uma filosofia vindoura

Our thesis tracks down and explores a method of reading Walter Benjamin´s texts and examines his proposal to a "coming philosophy" by highlighting his higher concept of "experience" (Erfahrung) for the foundation of a metaphysics for the Now-Time. Accordingly, it starts first from the application of the method and analyzes what is to be rescued from the Kantian legacy, as indicated in Benjamin´s youth "Program for a coming Philosophy" (1917-1918). Then, to discuss and evaluate Benjamin´s project of a "coming philosophy" several youth´s texts are compared with later texts which propose a new concept of experience as both aesthetic and historical basis for a philosophy of "NowTime" (Jetztzeit). Finally, by analogy with Kant´s critical attitude against dogmatic metaphysics the challenge of metaphysics today is discussed, especially Benjamin´s proposal to "Now-Time-Metaphysics" within the context of crisis and bankruptcy of explanatory models of reality in philosophy.
