Evaluating bone collagen extraction methods for stable isotope analysis in dietary studies

The specific purpose of this study was to compare three different collagen extraction methods commonly used in isotope laboratories conducting dietary studies. We evaluated their resultant differences in δ¹³C and δ¹⁵N, collagen quality and collagen yield. Our study was based on well-preserved skeletal material from the medieval period in Denmark. Our study shows that there is a systematic significant difference in the yield and the δ¹³C values between the three methods. Using the method of DeNiro and Epstein [DeNiro, M.J., Epstein, S., 1981. Influence of diet on the distribution of nitrogen isotopes in animals. Geochimica et Cosmochimica Acta 45, 341–351] with NaOH as cleaning agent, will, according to our study, give δ¹³C values that are on average ±0.32‰ more positive than using the ultra-filtration method [Brown, T.A., Nelson, D.E., Vogel, J.S., Southon, J.R., 1988. Improved collagen extraction by modified Longin method. Radiocarbon 30 (2), 171–177, modified in Richards, M.P., Hedges R.E.M., 1999. Stable isotope evidence for similarities in the types of marine foods used by late Mesolithic humans at sites along the Atlantic coast of Europe. Journal of Archaeological Science 26, 717–722]. The third method, which is a modified version of the second method, excluded the ultra-filtration step. This method seems to give δ¹³C values that lie in between the other methods. Our study did not show any significant difference in δ¹⁵N values. Although the differences between the methods are very small, we conclude that the use of stable isotope analysis in food determination studies requires adherence to routine methods for preparing and measuring samples.

SARUP REVISITED: ARCHAEOLOGICAL REALITY AND REALITIES OF ARCHAEOLOGY

In the second half of the 4^th millennium BC, we see significant changes in the early Neolithic culture. These take place some centuries after the initial introduction of agriculture and sees striking developments such as the apparent opening‐up of the landscape, involving forest clearance, the introduction of the ard for ploughing and the construction of regular houses. The transition to a settled and sedentary farming lifestyle must also have demanded mental adaptations, whereby the farmers were required to forge new and stable alliances. These alliances appear to be forged by a series of communal works, involving monumental structures, such as the building of dolmens and passage graves as well as the extensive and land‐demanding causewayed enclosures. The causewayed enclosures were essentially used for only a few days but were remembered for centuries. Since the 1970s, excavations have been undertaken in the Sarup area, on the island of Funen, Denmark, to obtain more detailed information about the activities that took place there between c. 3600 and 3000 BC. This paper presents the results of excavations and studies of two well‐preserved causewayed enclosures, the Barkaer‐structures and more than 30 megalithic monuments, as well as investigations of several settlements. This research has provided insight into a complex farming culture, which appears to have been firmly consolidated by major communal construction works, whereby teams and networks were created within an evolving cooperative social structure.     

Ideology and the history of ancient Israel

An answer to the recent criticism of Ian Provan and James Barr of the position of the so-called ''revisionists'' among Old Testament scholars. Provan - as well as Barr - accuses the revisionists for being ''ideologists'', i.e., that ideology has governed their research. This is a false accusation. The revisionists originally shared the ideology of the scholarship of the modern age. Only at a later date they adopted, forced by their analyses, an ideological approach to the reading of text that seems more on-line with ideas that are said to be postmodern.     

Using the Concept of Ethnicity in Defining Philistine Identity in the Iron Age

ABSTRACT

Normally the discussion about Philistine identity vis-à-vis Isra-elite identity moves on a macro basis: On one side the Philistines, and on the other the Israelites. Little attention has been paid to the related concept of “scale and social organization.” If we try to find a background for the macro definitions: Israelites, Philistines, we move on an imaginary level. It is a kind of literary concept nourished among the elite—never more than a few percent of any ancient society. The realities of ancient Palestine in the Iron Age were different. First of all nationality was an unknown concept, and any idea of ethnicity related to the issue of nationality (as in Avraham Faust's recent book on Israelite origins) is irrelevant. Second, there were, as argued by, among others Mario Liverani, no national borders in Antiquity. Borders were fiscal delimitations: Who paid tax to whom? Third, ethnicity follows the group, and a certain person may change identity as he moves through differ-ent groups. In a society of such small extent as ancient Palestine, each villager would have an identity defined by his village as against the members of the neighboring community—ethnicity cannot be separated from identity—and villagers living in one area will have a distinct consciousness of being differ-ent from those who live “on the other side of the river.” “National” identity, when the idea of ethnicity includes all people living within the fiscal borders of an ancient state, would hardly ever be called upon, except when the elite wanted to defend its privileges—its right to obtain taxes—against intruders. Thus the concept of a Philistine—Israelite controversy based on different ide-as about ethnicity is no more than a projection of modern ideas about the na-tional state which came into being two hundred years ago.     

A Review of: “Theodore L. Sourkes. The Life and Work of J.L.W. Thudichum (1828–1901).”

This article explores the short history of “neuroscience” as a discipline in its own right as opposed to the much longer past of the brain sciences. It focuses on one historical moment, the formation of the first British “neuroscience” society, the Brain Research Association (BRA), renamed in 1996 to the British Neuroscience Association (BNA). It outlines the new thinking brought about by this new science of brain, mind, and behavior, it sketches the beginnings of the BRA and the institutionalization of neuroscience in the British context, and it further explores the ambiguous relation the association had towards some of the ethical, social, and political implications of this new area of research.
