Left Ruins in Ethiopia: Imagining Otherwise Amid Necroepistemic Historiography

This essay uses the notion of necroepistemology to expose the killing of the other as executed by the neoliberal historiography in Ethiopia. Utilizing Fanonian negative dialectics, it critiques the ahistorical, immaterial, and reified object, as well as universal history, promoted by the official Ethiopian historiography’s absolute time, space, and matter. It does so to reveal the ways in which the enduring social questions and new imaginations are dismissed by this historiography as the work of the global-local left. To counterbalance this practice, I return to the 1974 Ethiopian socialist revolution and to the staging of Ethiopian socialism as a critical transnational rethinking of the human in the country. At the same time, attending to the everyday struggle of women performers in both the imperial and revolutionary spaces, the essay reminds us how the revolutionary practice, which had envisioned a new social human, ended up marking female performers’ bodies as dangerous for the socialist movement. Revealing the ways in which women performers collaborated with and fought against a male revolutionary figure, this essay ends with a call to respond to the current necroepistemic moment to draw attention to the historically vulnerable people who are dying in Ethiopia in the here and now.

The Iraqw society reflected in their language

A close inspection of the anthropological literature on Iraqw (Cushitic, Tanzania) reveals that central properties in their culture include the relative importance of social relations and hence community over kinship relations, the relevance of relative rather than absolute time, the centrality of space in culture and the importance of ritual cleansiness. The paper investigates to what extend the Iraqw language reflects this. Language being a social construct is expected to reflect social structure over time, both in lexicon and in grammar. Indeed the Iraqw language reflects their social structure in a number of way. Their verbal art emphasizes the need for peace in the community and is strongly communal in performance. This is evident, for example, in the rituals for lifting a curse. The centrality of community is reflected in various part of the lexicon. expression for pride being one of them, or the factor of companionship in possession. It is also grammaticalised in an extension of the function of the impersonal subject pronoun to express actions done together. Iraqw mythology and tales never attempt to indicate a point on time and only report chronology of event. This conceptualisation of time is reflected in the absence of lexical elements for absolute time and the abstract notion time. Furthermore the language forces specification of gender in any direct address: the second person pronoun is gender specified, kinship terms used for address are all gender specified as is the interjection for attention. Iraqw shows signs for a disappearing in-law respect register.

Locking Down Gender Roles? A Time-Use Perspective on Gender Division of Household Labour during the COVID-19 Pandemic Lockdown in Belgium

The impact of the COVID-19 pandemic on the division of household labour could continue to lock down or start to break gender roles. Using time-use data of n = 473 individuals collected during the lockdown restrictions in Belgium from March to May 2020, we analyse the gendered division of routine and non-routine household labour in absolute time use and relative shares. We compare against the Belgian time-use data of 2013 for the same time period ( n = 678 individuals). A time-demanding work and living situation associate with an increase in men’s time spent on household labour during the lockdown but not with a change in women’s time use. The gender gap closes in absolute time but not in relative shares of routine and non-routine household labour. The limited impact of the COVID-19 pandemic on the gender division of household labour indicates a temporal rather than a substantial change in gender roles.

Effects of order on memory of event times

Memorizing time of an event may employ two processes (1) encoding of the absolute time of events within an episode, (2) encoding of its relative order. Here we study interaction between these two processes. We performed experiments in which one or several items were presented, after which participants were asked to report the time of occurrence of items. When a single item was presented, the distribution of reported times was quite wide. When two or three items were presented, the relative order among them strongly affected the reported time of each of them. Bayesian theory that takes into account the memory for the events order is compatible with the experimental data, in particular in terms of the effect of order on absolute time reports. Our results suggest that people do not deduce order from memorized time, instead people’s memory for absolute time of events relies critically on memorized order of the events.

Newton’s Philosophy of Time

This chapter explains what Isaac Newton means with the phrase “absolute, true, and mathematical time” in order to discuss some of the philosophic issues that it gives rise to. It describes Newton’s thought in light of a number of scientific, technological, and metaphysical issues that arose in seventeenth‐century natural philosophy. The first section discusses some of the relevant context from the history of Galilean, mathematical natural philosophy, especially as exhibited by the work of Christiaan Huygens. The second section offers a close reading of what Newton says about time in the Principia’s Scholium to the definitions. It argues that Newton allows us to conceptually distinguish between “true” and “absolute” time from the vantage point of Newton’s dynamics. The third section, in the context of a brief account of Descartes’ views on time, discusses the material that Newton added to the second edition of the Principia in the General Scholium

Synchronization-Free RadChat for Automotive Radar Interference Mitigation

Automotive radar interference mitigation is expected to be inherent in all future ADAS and AD vehicles. Joint radar communications is a candidate technology for removing this interference by coordinating radar sensing through communication. Coordination of radars requires strict time synchronization among vehicles, and our formerly proposed protocol (RadChat) achieves this by a precise absolute time, provided by GPS clocks of vehicles. However, interference might appear if synchronization among vehicles is lost in case GPS is spoofed, satellites are blocked over short intervals, or GPS is restarted/updated. Here we present a synchronization-free version of RadChat (Sync-free RadChat), which relies on using the relative time for radar coordination, eliminating the dependency on the absolute time provided by GPS. Simulation results obtained for various use cases show that Sync-free RadChat is able to mitigate interference without degrading the radar performance.
