Introduction

The Introduction examines why “movement” is often invoked as a term in film criticism and film theory but is rarely analyzed as an aspect of film form. The reason for this is twofold. First, because film theory has largely examined movement only as a defining property of the cinematic medium, movement is rarely singled out in film criticism. Second, because film theory has inherited the philosophical intuition that form is primarily spatial rather than temporal, formal analysis in film studies tends to break up the temporal flow of film into static units, such as in shot breakdowns and frame analyses. In film studies, then, “form” and “movement” are conceptually incompatible. As a means of thinking motion and form together, the Introduction proposes the concept of “motion forms,” generic structures, patterns, or shapes of motion. The Introduction then explores the philosophical roots of the motion form in phenomenology and Gestalt psychology, and explains how such a way of thinking about cinematic motion differs from other phenomenological approaches in film studies. Finally, the introduction outlines the six chapters of the book, each of which investigates a particular motion form that emerges throughout the history of cinema.

Managing projects as a mode of temporal ordering. Performative organising of time and temporality in projects

Purpose Project studies analyse either managing practices or the temporal nature of project management, which leaves open a research gap: the temporality of managing practice. The paper demonstrates that performativity theory with a temporal perspective helps us to understand how managing a project organises limited temporal resources by aligning activities, deadlines or milestones to reach a goal in a given time.Design/methodology/approach The article utilises empirical data and grounded theory methodology. Ten interviews with project managers from two companies support empirically guided theory building and conceptual reasoning.Findings The article extends John Law's “modes of ordering” to a project-specific mode of temporal ordering. This mode of temporal ordering describes the underlying rationale of project managers who assign, order and materialise time to generate the temporal structure of the project.Research limitations/implications The conceptual nature of the paper and its limited empirical data restrict the generalisation of the findings. The article's goal is to initiate further research and to offer a set of tools for such research.Originality/value The contribution links managing practice and temporality in a performativity approach. This link focusses the actual actions of the managers and contextualises them in the temporal flow of the project. Managing projects as a mode of temporal ordering describes how project managers enact temporal structures and how they themselves and their activities are temporally embedded.

Application of Dynamic Mode Decomposition to Study Temporal Flow Behavior in a Saccular Aneurysm

Aneurysms are abnormal expansion of weakened blood vessels which can cause mortality or long-term disability upon rupture. Several studies have shown that inflow conditions spatially and temporally influence aneurysm flow behavior. The objective of this investigation is to identify impact of inflow conditions on spatio-temporal flow behavior in an aneurysm using Dynamic Mode Decomposition (DMD). For this purpose, low-frame rate velocity field measurements are performed in an idealized aneurysm model using Particle Image Velocimetry (PIV). The inflow conditions are precisely controlled using a ViVitro SuperPump system where non-dimensional fluid parameters such as peak Reynolds number (Rep) and Womersely number (α) are varied from 50-270 and 2-5, respectively. The results show the ability of DMD to identify the spatial flow structures and their frequency content. Furthermore, DMD captured the impact of inflow conditions, and change in mode shapes, amplitudes, frequency, and growth rate information is observed. The DMD low-order flow reconstruction also showed the complex interplay of flow features for each inflow scenario. Furthermore, the low-order reconstruction results provided a mathematical description of the flow behavior in the aneurysm which captured the vortex formation, evolution, and convection in detail. These results indicated that the vortical structure behavior varied with the change in α while its strength and presence of secondary structures is influenced by the change in Rep.

The Art that is Made Out of Time

This chapter asks, how do rhythm, temporality, and noise work through a range of media practices from painting, writing, music, and film? Artists have long employed an array of media to create what might be referred to as ‘sound art’, when that term is expanded, as it is here, to include all work that is prefaced on a temporal flow and set against the figure of noise. What is sound art? This question seems to have been asked a lot in recent times. The intention here is not to pose it again but to offer instead some concrete reflections on what happens when other artistic practices work through sound and noise?

Participatory Design as the Temporal Flow of Coalescing Participatory Lines

This paper argues that the existing literature on participatory design (PD) tends to focus on frontstage design interactions (workshops, participants, methodologies, techniques, etc.) to facilitate PD ‘here and now’—referred to as the interactional approach. In contrast, the paper proposes to contribute to an evolving literature, referred to as the transformational approach, that takes a more longitudinal line and which attends to both the frontstage and backstage within an extended temporal frame. To do this the paper draws on the work of the social anthropologist Tim Ingold, in particular, his concept of the happening of ongoing life as a bundle of flowing lines. The paper argues that PD becomes possible when ongoing participation is conceived of as a set of corresponding (or coalescing) and conditioning lines of flow—each line with its own history, attentionality, rhythms, tempos and so forth. To illustrate what this reorientation might mean for PD the paper draws on an in-depth action research study of a PD initiative that sought to develop a digital service to address loneliness and social isolation in a rural location in the UK. The paper explores how project members, individual participants, non-governmental organisation, government representatives, evaluators and funders co-responded to each other (or not) as they engaged, or became implicated, in the PD process. The paper concludes with some practical implications of what such an Ingoldian reorientation might mean for the ongoing development of PD as a transformational methodology.

Genetic determination of regional connectivity in modelling the spread of COVID-19 outbreak for improved mitigation strategies

ABSTRACTCovid-19 has resulted in the death of more than 1,500,000 individuals. Due to the pandemic’s severity, thousands of genomes have been sequenced and publicly stored with extensive records, an unprecedented amount of data for an outbreak in a single year. Simultaneously, prediction models offered region-specific and often contradicting results, while states or countries implemented mitigation strategies with little information on success, precision, or agreement with neighboring regions. Even though viral transmissions have been already documented in a historical and geographical context, few studies aimed to model geographic and temporal flow from viral sequence information. Here, using a case study of 7 states, we model the flow of the Covid-19 outbreak with respect to phylogenetic information, viral migration, inter- and intra- regional connectivity, epidemiologic and demographic characteristics. By assessing regional connectivity from genomic variants, we can significantly improve predictions in modeling the viral spread and intensity.Contrary to previous results, our study shows that the vast majority of the first outbreak can be traced to very few lineages, despite the existence of multiple worldwide transmissions. Moreover, our results show that while the distance from hotspots is initially important, connectivity becomes increasingly significant as the virus establishes itself. Similarly, isolated local strategies-such as relying on herd immunity-can negatively impact neighboring states. Our work suggests that we can achieve more efficient unified mitigation strategies with selective interventions.
