Plants are edging closer to the center of critical inquiry in the Anthropocene because they are intimately tied to legacies of settler colonialism, forced migration, related practices of extractive capitalism, and their environmental and human harm. Ostensibly sessile, plants travel constantly through their adaptations to ensure their survival and reproduction. In the modern period, this movement was taken to unprecedented scale by humans, triggering massive displacement of people and disruption to ecosystems. Among the many instances of plant movement, the scandalous (...) mobility of invasives unsettles us because it exposes the worst excesses of the Anthropocene. This essay focuses on the practice of multimedia artist Precious Okoyomon, whose installations feature prominently kudzu, the most notorious weed in the US. The highest concentrations of kudzu are found in the former Cotton Belt—Georgia, Alabama, and Mississippi—making it cotton’s unlikely successor. The essay analyzes how Okoyomon’s kudzu installations explore the dark side of the landscape, peeling off layers of human and environmental harm while acknowledging the resilience of more-than-human life. But a focus on invasive species also challenges plant theory’s celebration of entanglement, showing how the theoretical effort to produce the plant as a generalized concept bumps against the contingencies of its natural history in time and place, its ontological slipperiness, its ethical ambiguity.

This paper analyses and compares some of the automated reasoners that have been used in recent research for compliance checking. Although the list of the considered reasoners is not exhaustive, we believe that our analysis is representative enough to take stock of the current state of the art in the topic. We are interested here in formalizations at the _first-order_ level. Past literature on normative reasoning mostly focuses on the _propositional_ level. However, the propositional level is of little usefulness for (...) concrete LegalTech applications, in which compliance checking must be enforced on (large) sets of individuals. Furthermore, we are interested in technologies that are _freely available_ and that can be further investigated and compared by the scientific community. In other words, this paper does not consider technologies only employed in industry and/or whose source code is non-accessible. This paper formalizes a selected use case in the considered reasoners and compares the implementations, also in terms of simulations with respect to shared synthetic datasets. The comparison will highlight that lot of further research still needs to be done to integrate the benefits featured by the different reasoners into a single standardized first-order framework, suitable for LegalTech applications. All source codes are freely available at https://github.com/liviorobaldo/compliancecheckers, together with instructions to locally reproduce the simulations. (shrink)

The chromosomes of eukaryotic cells possess many potential DNA replication origins, of which a subset is selected in response to the cellular environment, such as the developmental stage, to act as active replication start sites. The mechanism of origin selection is not yet fully understood. In this review, we summarize recent observations regarding replication origins and initiator proteins in various organisms. These studies suggest that the DNA‐binding specificities of the initiator proteins that bind to the replication origins and promote DNA (...) replication are primarily responsible for origin selection. We particularly focus on the importance of transcription factors in the origin selection process. We propose that transcription factors are general regulators of the formation of functional complexes on the chromosome, including the replication initiation complex. We discuss the possible mechanisms by which transcription factors influence the selection of particular origins. BioEssays 27:1107–1106, 2005. © 2005 Wiley Periodicals, Inc. (shrink)
