Rethinking Filter: An Interdisciplinary Inquiry into Typology and Concept of Filter, Towards an Active Filter Model

Abstract

This works aims to re-investigate different aspects of a variety of filters and filtration processes within diverse realms of knowledge from an interdisciplinary point of view, and develop a comprehensive Active Model of Filter that accommodates the phenomena in its entire diversity and complexity. The Active Filter Model proposes to take Filter—from various fields and scales operating at material and symbolic level—not as mere objects, but as difference-producing phenomena that need to be addressed as complex active systems within event-based boundaries. The model underlines a systemic, operative, performative, and negentropic nature to the phenomena that invites one to; recognize various elements and intra-actions within a filter system; follow chains of operations and processes that render the activity; take the performative and ecology building aspect of the filter activity into consideration; and acknowledge the negentropic, order-producing nature of filtering phenomena. The Active Filter Model is meant to serve as a foundation for further analysis and synthesis in various fields dealing with Filter, and the research approach is put forward as a paradigm for how seemingly disciplinary concepts such as Filter can be rethought through interdisciplinary methods, and mutually complement research questions within active matter, biology, information philosophy, data science and sustainability discourses.

“…Probably no other structure of animals embodies the multifarious functionalities of sophisticatedly combined carbohydrates and glycoproteins (Kimura et al, 2001; Kimura & Itoh, 2007; Riehl, 1993) like the appendicularian house. While the general internal structure and functional aspects of the appendicularian house are well documented (Flood, 1991, 2003, Deibel, 1986, Fenaux, 1986; an excellent review of the research history leading to our current functional understanding of appendicularian houses is found in Flood & Deibel, 1998—see further literature there), many details are still in need of exploration (see, e.g., Conley et al, 2018; Katija et al, 2020, Razghandi & Yaghmaei, 2020).…”
