Erving Goffman at 100: A Chameleon Seen as a Rorschach Test within a Kaleidoscope

open access: yesSymbolic Interaction, EarlyView.
The 100th anniversary of Erving Goffman's birth was in 2022. Drawing on his work, the Goffman archives, the secondary literature, and personal experiences with him and those in his university of Chicago cohort, I reflect on some implications of his work and life, and the inseparable issues of understanding society.

Can Extremal Black Holes Have Non-Zero Entropy ? [PDF]

open access: yes, 1996
We give several pieces of evidence to show that extremal black holes cannot be obtained as limits of non-extremal black holes. We review arguments in the literature showing that the entropy of extremal black holes is zero, while that of near-extremal ...

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

An Overview of the Rock Art of AlUla: Tracing Changes in Content and Form Across 12,000 Years of Human History

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,

Competition and payments to African chiefs on the Gold Coast during the slave trade, 1679‒1704

open access: yesThe Economic History Review, EarlyView.
Abstract The manuscript records of the Royal African Company show that the Company paid African chiefs for access to trade along the caravan routes on the Gold Coast in the seventeenth century. This paper documents and examines these payments. Using an event study, I establish that after the Glorious Revolution in 1688 when the Company's monopoly in ...

From black strings to fundamental strings: non-uniformity and phase transitions

open access: yesJournal of High Energy Physics
We discuss the transition between black strings and fundamental strings in the presence of a compact dimension, S z 1 $$ {\mathbbm{S}}_z^1 $$ . In particular, we study the Horowitz-Polchinski effective field theory in ℝ d × S z 1 $$ {\mathbb{R}}^d\times {

Boosts, Schwarzschild Black Holes and Absorption cross-sections in M theory [PDF]

open access: yes, 1997
$D$ dimensional neutral black strings wrapped on a circle are related to $(D-1)$ dimensional charged black holes by boosts. We show that the boost has to be performed in the covering space and the boosted coordinate has to be compactified on a circle ...
