War,memes and memeplexes

Meme theory has been attracting much attention in recent years. Pioneered by Richard Dawkins and Daniel Dennett it suggests that there are self‐replicating units of culture analogous to genes. Like genes these ‘memes’ seek to copy themselves as widely as possible. One of them may be war. Memetics remains in its infancy but the truly sobering aspect is that ‘fitness of purpose’ for a meme may have little to do with the biological fitness of the people who are ‘programmed’ by it; it simply evolves because it is advantageous for itself. Memes also persist because they flourish in the presence of other memes (such as religion) in what Dawkins calls ‘memeplexes’. One of the most persistent memes is honour, and another is revenge for dishonour imagined or real. War is a powerful medium for both. Even if meme theory never catches on it encourages us to think about war more creatively.     

HOUSES, DEFENCES AND STATUS; THE TOWNS OF ROMAN BRITAIN IN THE SECOND HALF OF THE SECOND CENTURY A.D.

Summary. The appearance of spacious and well-equipped houses in the towns of Roman Britain from the mid second century, following an initial period of resistance to urban dwelling on the part of the wealthy, requires explanation. Various possible motivating factors—the increasing prosperity of villa owners, the desire for security, official pressure coupled with renewed imperial interest in urban development, the availability of cheap building land, the example of the coloniae and the promotion of towns to higher rank—are considered. In many cases a combination of these factors will have applied, but the growing prestige of the towns themselves seems to have been a powerful attraction.     

HAM HILL STONE: A MEDIEVAL DISTRIBUTION PATTERN FROM SOMERSET

This paper explores the potential of simple quantitative techniques for elucidating a medieval distribution pattern. The distribution is that of a distinctive building-stone found in parish churches in Somerset and throughout the south-west. Dating is achieved by recognition of different architectural styles and the stone's occurrence is plotted within 25 km of the source quarry at Ham Hill near Yeovil. The study has dual implications in that simple statistical techniques enable new conclusions to be made concerning the mechanisms of the stone's distribution, but some of these conclusions can also be checked against the documentary evidence. Therefore both distribution and techniques come under scrutiny. In this way a complementary archaeological and historical approach united by quantitative techniques and documents is applied to a medieval distribution problem but has implications for the prehistorian also.     

Joseph P. Bradley's Journey: The Meaning of Privileges and Immunities

Justice Joseph P. Bradley of New Jersey will forever be remembered as the judge who in 1883 cruelly scorned black rights in the Civil Rights Cases . ¹ Yet Bradley's position that year marked the end of a journey that had started in a quite different place. Thirteen years before, when he first joined the Court, Bradley had read Fourteenth Amendment protections of citizens' rights expansively, believing that "it is possible that those who framed the [Fourteenth Amendment] were not themselves aware of the far reaching character of its terms." In 1870 and 1871, Bradley wrote that the Fourteenth Amendment's Privileges and Immunities Clause reached "social evils … never before prohibited" and represented a commitment to " fundamental " or "sacred" rights of citizenship that stood outside the political process and "cannot be abridged by any state." ² By 1883, however, Bradley had turned away from such views. In the Civil Rights Cases , he wrote that nothing in the Thirteenth or Fourteenth Amendments countenanced a law against segregation. Blacks, he said, must take "the rank of mere citizen" and cease "to be the special favorite of the laws." ³     

2. WRITING POLITICS BACK INTO HISTORY1

This essay examines the writing of history and historiography in early modern south India as discussed in the book Textures of Time. The book argues that a historical and historiographical awareness was prevalent in south India prior to the arrival of a European field of knowledge under colonial rule. However, this essay maintains that the book unwittingly reproduces some of the very same Eurocentric formulations of the writing of history and modernity that it seeks to refute. A liberal conception of modernity is at the core of how society, history, and politics have been imagined in this book. These attributes of modernity, such as history as a set of causal relations, as presentation of facts, as a realm of the real cannot escape their prior formulation in Europe. The liberal social order also underpins the relationship between writing and the world. In Textures, early historians merely represent reality; they are not authors whose practices are constitutive of politics and identity. The conception of modernity overlooks the constitutive role colonial empires played in the very creation not only of the West and non‐West, but also in conceptions of the real, the modern, the universal, and the historical.     

Changes in stream channel morphology at tributary junctions,Lower Hunter Valley,New South Wales

Many empirically derived models of downstream changes in channel form are based on the concept of hydraulic geometry, whereby changes in channel morphological variables are related by a continuous power function to increasing discharge or its surrogate. However, changes in discharge throughout a drainage basin are normally concentrated at the junctions of stream channels. At junctions, the relationship between discharge and channel morphology is discontinuous. Some Lower Hunter Valley stream channels were surveyed upstream and downstream of tributary junctions. While significant regional downstream relationships were established, consistent trends at tributary junctions were not apparent from the data. It is possible that considerable scatter evident in ratios of change on either side of each junction was due to local within-site variability. In addition, the relative timing of discharge inputs and the nature of introduced sediment loads could be important in determining the magnitude and direction of channel change at tributary junctions. Interrelated changes in cross-sectional, profile and planform variables may be expected below junctions. The resultant channel morphology, in terms of these variables, might not be wholly determinate.     

NITRATE-NITROGEN FLUX AND UTILIZATION IN A STREAM ECOSYSTEM DURING LOW SUMMER FLOWS

Analysis of nitrate transport in the downstream reaches of Duffin Creek, Ontario, revealed an average daily loss of 45 kg nitrate-N during low summer flows. The nitrate loss represents 50 per cent of the average daily input of total nitrogen and 75 per cent of the nitrate input received by these channel reaches. Nitrate uptake by benthic algae appears to account for a small portion of the NO₃^- removal. Laboratory experiments suggest that most of the nitrate disappearance from the river reaches is caused by bacterial denitrification and nitrate reduction in stream sediments. L'analyse du transport de nitrate dans l'étendue en aval de Duffin Creek, Ontario, a révélé une perte journalière moyenne de 45 kg de nitrate-N durant l'écoulement affaibli des flots du ruisseau en été. Cette perte de nitrate représente 50 pourcent de la moyenne journalière du total d'azote fourni et 75 pourcent du nitrate reçu par l'étendue de ce canal. Les algues agrostides ne semblent être responsable que d'une faible partie de ladisparition du NO₃^-. Des experiences en laboratoire suggèrent que presque toute la disparition du nitrate dans la riviere est causée par la dénitrification bactérienne et la réduction d'azote dans les sédiments du cours d'eau.
