The Athenian recovery of Theseus’ bones from Scyros is known through a number of literary accounts spanning several centuries. The tradition dates the recovery to the early fifth century and connects it to the Athenian statesman Cimon. Modern reconstructions tend to rely on the combination of different (and possibly conflicting) sources. An analysis of the evidence, however, shows that the stor...
Persistent seed banks may provide information on historical changes in the genetic composition of populations. We used stratified sampling of the soil seed bank of Astragalus bibullatus (Pyne's ground plum) to assess levels of temporal variation in population genetic structure and to infer historical changes in the levels of inbreeding and relative gene flow. This species has an extremely limit...

leather artifacts have organic and degradable structure and some historic samples have remained from different historical periods. studies of these scarce specimens have a great importance in the conservation procedure by which the structural study of leather artifact for understanding production process and used materials can be achieved. for this purpose a historic leather bottle has been stu...
Despite widespread belief that redlining contributed to disinvestment in cities, there has been little empirical analysis of historical lending patterns. The lack of appropriate data and clear definitions of redlining has contributed to this void. This article reviews definitions and methods that have emerged from research on lending in recent years and considers how they can be applied to rese...
The structure of near-wall layers has been the subject of much research over many years, with conceptual descriptions of the Attached Eddy Hypothesis (AEH, henceforth) by Townsend (1980) and Perry & Chong (1982) being key historical fix points. The fact that major efforts have continued unabated over the past two to three decades reflects the exceptional structural complexity of near-wall layer...
The explanation of how and why firms succeed or fail is a recurrent research challenge. This is particularly important in the context of technological innovations. We focus on the role of historical events and decisions in explaining such success and failure. Using a case study of Nokia, we develop and extend a multi-layer path dependence framework. We identify four layers of path dependence: t...
the present study aimed at investigating how different news agencies using the concept of legitimation/delegitimation represent the same event differently. to this end, van leeuwens (2008) legitimatory/delegitimatory framework was applied to the data gleaned from the iranian state-run news agency fars news, british state-run news agency bbc, and also american state-run news agency voa. the resu...
Humanities scholars increasingly rely on digital archives for their research instead of time-consuming visits to physical archives. This shift in research method has the hidden cost of working with digitally processed historical documents: how much trust can a scholar place in noisy representations of source texts? In a series of interviews with historians about their use of digital archives, w...
This paper examines the effects of strategic alliances on non-financial firms’ bank loan financing. We construct several measures to capture firms’ alliance activities using the frequency of alliance activities, the prominence of the alliance partner and the relative networking position in the overall alliance network. We find that firms with active alliance involvement experience a lower cost ...
