Using Visual Systems Mapping to Improve Transparency and Comparability of Life Cycle Assessment Baseline Scenarios

open access: yesSystems Engineering, EarlyView.
ABSTRACT Visual systems mapping is a systems engineering approach used to represent complex processes and interactions. This study evaluates its application for documenting assumptions in life cycle assessment (LCA) baseline scenarios. In LCA, the baseline or reference case represents the business as usual system against which changes in impacts (e.g.,

Seriality and style: The embodiment, perception, and normalization of collectives

open access: yesThe Southern Journal of Philosophy, EarlyView.
Abstract Within existential phenomenology, both seriality and style have been drawn on to theorize the embodiment and perceptibility of (social) ontological differences. While style refers to how we encounter the world and others not in the abstract, but as immediately and intuitively meaningful, seriality is a form of collective being that pertains to
