John Marshall Harlan's Political Memoir

Near the end of his life, John Marshall Harlan wrote a number of biographical essays, presumably at the request of his children. Most of the essays relate to his experiences in the Civil War. The essay reprinted here instead recounts Harlan's political career before he joined the Supreme Court. Although he rarely won any elections and only held a couple of offices, Harlan's political odyssey is significant in that it shows how his social views were formed. Harlan's transformation from a staunch anti‐abolitionist to a civil‐rights advocate can be viewed as a series of reactions against various opponents as he struggled to find his political identity after the collapse of the Whig party in the 1850s.     

SHAKING TABLE DYNAMICS: RESULTS FROM A TEST-ANALYSIS COMPARISON STUDY

This paper presents the results of a comprehensive comparison study between the analytically predicted and experimentally identified dynamics of the shaking table system built recently in the Structural Engineering Laboratory at Rice University in Houston, Texas. The primary objectives of the research presented here are two-fold: (1) to shed light into the dynamic performance of asmall-tc-medium size, uni-axial, servo-hydraulic, displacement-controlled shaking table system, and (2) to validate a linearised dynamic model of the system (in the form of the total shaking table transfer function) developed earlier by the authors from basic principles. The analytical model incorporates the inherent dynamic characteristics of the various components of the shaking table system (i.e. controller, servovalve, actuator, test specimen, and reaction mass) and their dynamic interaction.

The test-analysis correlation study performed over a wide range of operating and payload conditions provides useful information on the sensitivity of the shaking table transfer function to control gain parameters and how it can be used to tune the shaking table controller for optimum performance under various payload conditions. The good test-analysis correlation results obtained validate the analytical shaking table model, show its robustness, and provide keen insight into the underlying coupled dynamics of a shaking table system. In order to achieve this good test-analysis correlation, it was crucial to include a time delay in the analytical model of the shaking table system (innovative feature of the model to account for the time lag in the response of the servovalve-actuator system). The expected significant dynamic interaction between payload and shaking table is also confirmed by this study.     

STATISTICAL EVALUATION OF THE PRESENTLY ACCUMULATED LEAD ISOTOPE DATA FROM ANATOLIA AND SURROUNDING REGIONS

Several hundred new stable lead isotope ratio determinations of ore and slag specimens from ancient mining sites throughout Anatolia and of samples of artefacts of the Chalcolithic, Bronze Age and Early Iron Age from museum collections in Turkey and the United States have been combined with the accumulated published isotope determinations of such specimens from throughout the eastern Mediterranean and Aegean regions to form a data base of nearly 1000 analyses. It is the purpose of this paper to evaluate the practical effectiveness of using this now extensive data base to discriminate between the many sources of metals throughout this region and to propose methods to enhance this discrimination. By using the full three-dimensional isotopic data in multivariate statistical treatments and by separating isotopically resolvable source groups within some of the source areas and isolating statistically outlying specimens from them, it has been possible to characterize some ore sources more precisely and compactly and thereby achieve better resolution between ore sources. It has also been possible to isolate isotopically compatible artefact groups which possibly relate to ore sources that, as yet, have not been well defined by isotopic analysis.     

RADIOCARBON MEASUREMENTS ON A FLOATING TREE-RING CHRONOLOGY FROM NORTH-EAST SCOTLAND

Radiocarbon measurements have been performed on a 250 year ‘floating’ tree-ring section recovered from an archaeological site in north-east Scotland. Short term fluctuations in atmospheric concentration appear to be superimposed on a general trend of decreasing ambient ¹⁴Cparallel with tree growth. The most significant finding is the range of dates obtained from the sequence, namely 400 years, since it implies that the error on a single radiocarbon date is considerably greater than at present accepted on the basis of analytical precision alone.     

A Powerful Place of Pictland: Interdisciplinary Perspectives on a Power Centre of the 4th to 6th Centuries ad

OUR UNDERSTANDING of the nature of late and post-Roman central places of northern Britain has been hindered by the lack of historical sources and the limited scale of archaeological investigation. New work at Rhynie, Aberdeenshire, Scotland (NJ 49749 26345), has begun to redress this through extensive excavation and landscape survey. This has revealed a Pictish central place of the 4th to 6th centuries ad that has European connections through material culture, iconography and site character. In addition to reviewing the place-name and historical context, this article outlines preliminary reflections on five seasons of excavation and survey in the Rhynie landscape. The article also provides a detailed consideration of chronology, including radiocarbon dating and Bayesian statistical analysis. The results reveal the multi-faceted nature of a major, non-hillfort elite complex of Pictland that comprised a high-status residence with cult dimensions, a major centre for production and exchange, and a contemporary cemetery. A series of sculptured stones stood in association with the settlement and cemetery and the iconography of the stones, along with the wider archaeological evidence, provides a rich dataset for a renewed consideration of the central places of early medieval northern Britain with broader implications for the nature of power and rulership in late and post-Roman Europe.     

Of squatting amid capitalism on Yangon's industrial periphery

Across major cities throughout the world, inflated real-estate markets continue to exacerbate crises of affordable housing. Amid such conditions, squatting has emerged as a means to claim urban residence while bypassing the rule of property, resulting in densely populated informal settlements stretched along urban peripheries, most notably in the Global South. But in what respect might squatting be said to have anti-capitalist content? But does the challenge squatting poses to private property mean the practice is unambiguously anti-capitalist? The case presented here illustrates how squatting – initially a challenge to the rule of private property – becomes imbricated with wider relations of extraction and rule and with the broader capitalist context more generally.
