Detecting Compaction Disequilibrium with Anisotropy of Magnetic Susceptibility

In clay-rich sediment, microstructures and macrostructures influence how sediments deform when under stress. When lithology is fairly constant, anisotropy of magnetic susceptibility (AMS) can be a simple technique for measuring the relative consolidation state of sediment, which reflects the sediment burial history. AMS can reveal areas of high water content and apparent overconsolidation associated with unconformities where sediment overburden has been removed. Many other methods for testing consolidation and water content are destructive and invasive, whereas AMS provides a nondestructive means to focus on areas for additional geotechnical study. In zones where the magnetic minerals are undergoing diagenesis, AMS should not be used for detecting compaction state. By utilizing AMS in the Santa Barbara Basin, we were able to identify one clear unconformity and eight zones of high water content in three cores. With the addition of susceptibility, anhysteretic remanent magnetization, and isothermal remanent magnetization rock magnetic techniques, we excluded 3 out of 11 zones from being compaction disequilibria. The AMS signals for these three zones are the result of diagenesis, coring deformation, and burrows. In addition, using AMS eigenvectors, we are able to accurately show the direction of maximum compression for the accumulation zone of the Gaviota Slide

Resilience, resistance, infrapolitics and enmeshment

A great deal has been written in the International Relations literature about the role of resilience in our social world. One of the central debates in the scholarship concerns the relationship between resilience and resistance, which several scholars consider to be one of mutual exclusivity. For many theorists, an individual or a society can either be resilient or resistant, but not both. In this article, we argue that this understanding of the resilience–resistance connection suffers from three interrelated problems: it treats resilience and resistance as binary concepts rather than processes; it presents a simplistic conception of resilient subjects as apolitical subjects; and it eschews the ‘transformability’ aspect of resilience. In a bid to resolve these issues, the article advocates for the usefulness of a relational approach to the processes of resilience and resistance, and suggests an approach that understands resilience and resistance as engaged in mutual assistance rather than mutual exclusion. The case of the Palestinian national liberation movement illustrates our set of arguments

Insurrecciones no armadas : movimientos de poder popular en regímenes autoritarios

En las dos últimas décadas del siglo XX, una oleada de movimientos de \u93poder popular\u94 estalló en países no democráticos. Kurt Schock compara los éxitos del movimiento Anti-Apartheid en Sudáfrica, el movimiento de Poder Popular en Filipinas, el movimiento Prodemocracia en Nepal, y el Movimiento Antimilitarista en Tailandia, con los fracasos de los movimientos de prodemocracia en China y el desafío contra el régimen en Burma. Al examinar cómo esos métodos de protesta promovieron cambios del régimen en algunos países, pero no en otros, este libro proporciona un singular discernimiento en un campo que ha sido examinado con superficialidad y que es poco entendido, este es el del poder de la acción no-violenta
