This paper explores alterations in social dynamics caused by coca crops in Curvaradó and Jiguamiandó, at Choco department in the Colombian Pacific region. The research analyzes the role of armed actors such as paramilitaries and guerrillas in the conformation of new social spaces where local people find resistance as the main tool to survive in chaotic environments. Local power as a politics of resistance is also analyzed. Non-governmental organizations are a key tool to comprehend new social configurations. By doing the analysis and comparison using political ecology as the theoretical background along with concepts of moral economy and everyday resistance, with qualitative research methods. The paper aims to interpret and provide a better understanding of those changes considering social-environmental relations. Findings suggest that those changes in social structure are leading to an understanding, not just of the organization of the area, but also that social dynamics and coca crops cannot be generalized in the country.

In simultaneous analyses of multiple data partitions, the trees relevant when measuring support for a clade are the optimal tree, and the best tree lacking the clade (i.e., the most reasonable alternative). The parsimony-based method of partitioned branch support (PBS) forces each data set to arbitrate between the two relevant trees. This value is the amount each data set contributes to clade support in the combined analysis, and can be very different to support apparent in separate analyses. The approach used in PBS can also be employed in likelihood: a simultaneous analysis of all data retrieves the maximum likelihood tree, and the best tree without the clade of interest is also found. Each data set is fitted to the two trees and the log-likelihood difference calculated, giving partitioned likelihood support (PLS) for each data set. These calculations can be performed regardless of the complexity of the ML model adopted. The significance of PLS can be evaluated using a variety of resampling methods, such as the Kishino-Hasegawa test, the Shimodiara-Hasegawa test, or likelihood weights, although the appropriateness and assumptions of these tests remains debated.

In 3 experiments, the authors examined the role of memory for prior instances for making relative judgments in conflict detection. Participants saw pairs of aircraft either repeatedly conflict with each other or pass safely before being tested on new aircraft pairs, which varied in similarity to the training pairs. Performance was influenced by the similarity between aircraft pairs. Detection time was faster when a conflict pair resembled a pair that had repeatedly conflicted. Detection time was slower, and participants missed conflicts, when a conflict pair resembled a pair that had repeatedly passed safely. The findings identify aircraft features that are used as inputs into the memory decision process and provide an indication of the processes involved in the use of memory for prior instances to make relative judgments.
