Irrigated taro (Colocasia esculenta) farming in North Kohala,Hawai‘i: sedimentology and soil nutrient analyses

How did traditional farming transform the natural environment in the Hawaiian Islands? This question is one that has largely been addressed for rainfed farming of crops like sweet potato (Ipomoea batatas), but evidence is lacking for irrigated farming of the critical staple crop taro (Colocasia esculenta). We describe the results of soil nutrient and sedimentological analyses of deeply-stratified pondfield deposits representing a 600-year-long record of irrigated taro farming in the North Kohala District, Hawai‘i Island. Soil is categorized by particle size to determine modes of transport and deposition, and concurrent soil nutrient analyses were conducted to infer shifts in the source of sediments and changes associated with taro harvesting. The advent of farming is clearly detectable in sedimentology, the presence of charcoal found within sediments, and soil chemistry. However, diminished nutrient concentrations can be attributed largely to deposition of a mixture of upstream sediments. Overall, there is no clear evidence for nutrient draw-down by taro harvesting, but we cannot yet rule it out as a factor. This study demonstrates the inherent difficulty of correlating changes in soil nutrients evident in irrigated pondfields with the long term history of soil nutrient cycling.     

Carbon and nitrogen isotope signals in eel bone collagen from Mesolithic and Neolithic sites in northern Europe

Carbon and nitrogen isotope analysis was undertaken on collagen extracted from eel bone from six Mesolithic and Neolithic sites in northern Europe. The results were compared with data obtained on other archaeological fish remains and modern eel caught in fresh and brackish water and from the sea. The possibility of discriminating between freshwater, brackish and marine signals in archaeological eel bone is evaluated and the implications for archaeology discussed. Our data suggest that eel found at coastal Mesolithic and Neolithic sites have carbon isotope signals consistent with a marine origin with no evidence of freshwater residency. The sample of eel bone from one inland site is small but indicates carbon isotope values more consistent with freshwater residency or at least values intermediate between freshwater and marine carbon pools.     

The land of parrots

New settlements play an important role in planning for new residential needs. These arise from population growth, household change or de‐concentration from urban centres. The designation of a new settlement is a complex process as shown by the experience in Grampian Regional Council. This case study raises a number of questions for the effectiveness of strategic and local planning in Scotland and the rest of the UK.

The Belgammel Ram,a Hellenistic‐Roman Bronze Proembolion Found off the Coast of Libya: test analysis of function,date and metallurgy,with a digital reference archive

The Belgammel Ram was found off the coast of Libya in 1964, and examined during 2008–9. The following techniques were used: surface non‐contact digitizing using a laser scanner, reflectance transformation imaging using polynomial texture mapping and hemi‐spherical harmonics, digital photogrammetry with dense surface modelling, structured light optical scanning, and X‐ray fluorescence analysis. For internal structure the ram was examined by X‐radiography and 3‐D X‐ray tomography. Metallurgical composition was studied by micro‐drilling and subjecting the samples to scanning electron microscope X‐ray micro‐analysis, micro X‐ray fluorescence and X‐ray backscatter. The lead isotope composition was analysed. The alloy has average percentage composition Cu = 86.9, Sn = 6.3, Pb = 6.6, and Zn = < 0.10. The Belgammel Ram is probably a Hellenistic‐Roman proembolion from a small military vessel or tesseraria. The archived data are at the Faculty of Engineering and Environment, Engineering Sciences, Material Data Centre, University of Southampton ( muvis@soton.ac.uk ).     

Italian identity: Catholic responses to secularist definitions,c.1910–48

In united Italy, assertions by Catholic militants about their nation's true identity have been bound up with polemic against secularist forces and with claims about the position due to the Church in Italian society. They have insisted that Italy's authentic traditions are Catholic and that her true greatness resides in her being the heart of Christian civilization. Hostile or threatening ideologies, e.g. idealist philosophy and Communism, have been stigmatized as alien to Italian tradition. In the face of Fascism, with which the ‘Catholic world's’ relations were ambivalent, there was a major ideological campaign to assert a Catholic definition of the keyword romanità. The way in which Catholic theoreticians have defined the ‘nation’ in organicist terms have been linked to strategies of ideological defence against state forms, whether liberal or Fascist, perceived to be overweening.
