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."

Data compilation on the biological response to ocean acidification: environmental and experimental context of data sets and related literature

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

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.
