Quantitative analysis of two low-cost aerial photography platforms: A case study of the site of Zagora,Andros, Greece

Aerial photography provides a valuable recording method for archaeological sites and is often underutilized. In the past, aerial photographic platforms were expensive and often required highly specialized equipment. However, with new technology a variety of different platforms are now available. This paper will analyze two low cost aerial photographic platforms used at the Australian Archaeological Institute at Athens/University of Sydney's project at Zagora, on the island of Andros, Greece. Over two years, both kites and drones were used with relative success. Through a review of the application of both systems on the project, along with a quantitative analysis of the cost, transportability, operation and quality of photographs, the strengths and weaknesses of both platforms will be discussed.     

Quantifying how much raw material is needed: A case study based on the weight of the lithic artefacts from the Brno-Štýřice III Epigravettian site (Moravia,Czech Republic)

This paper compares the quantification of different raw materials in a chipped stone assemblage by weight and by number at the site of Brno-Štýřice III in Moravia, Czech Republic. The use of the same reduction technology for all raw materials means that the Brno-Štýřice III assemblage is a good case study. The result demonstrates that semi-local raw material tends to dominate numerically, but in terms of weight, there is a significant change in the predominant raw material. The paper contextualizes the results in relation to other assemblages and discusses the possible reasons for this phenomenon.

Korean unification: a solution to the challenges of an increasingly elderly population?

South Korea experienced below replacement fertility for the first time in 1983, which also marked the point from which fertility rates continued to decline over the next 20 years to reach a low of 1.2 in 2003. In spite of recent pronatalist policies, the fertility rate has remained near this level and has not increased appreciably. The reasons for sustained low fertility in South Korea are complex and solutions remain elusive. One option that has been suggested is reunification with North Korea, which could address the eventual decline in the population and mitigate the increasing proportion of the elderly. Although the conditions surrounding the German reunification experience were vastly different than what Korea will likely undergo, it is informative to look at Germany as a guide to the demographic parameters of reunification. Three projection models for 2015–2050 are presented; even the highest fertility models show that reunification will not be the answer to population restructuring already underway in South Korea as a result of sustained low fertility.

The estimation of live fish size from archaeological cranial bones of the New Zealand blue cod Parapercis colias

Twenty-four measurements were taken on five of the paired cranial bones and the otoliths of a modern sample of 177 blue cod. Parapercis colias. Regression analysis was performed on these measurements to estimate live fork length and ungutted weight. A number of regression models were examined (linear, logarithmic, exponential and power curve) to work out the optimum estimator for each bone measurement. It was found that live fork length of this species can be estimated with a standard error of less than ±28 mm, and the weight to less than ±140 g. Coefficients are provided for 48 equations linking bone size to live characteristics. This is followed by a study of blue cod from an archaeological site at Waihora in the Chatham Islands. Measurements were made on 8036 archaeological bones with a minimum number of individuals of 2547. It was found that the blue cod catch had near normal characteristics, with a mean fork length of 327 mm and SD of 57 mm. The mean body weight was estimated at 569 g. The usable meat weight represented by these fish is estimated to be 1.0 t. © 1997 John Wiley & Sons, Ltd.

Bone weight: new reference values based on a modern Portuguese identified skeletal collection

Skeletal weight and/or weight of the different bones of the human skeleton are currently used in a wide range of applications such as archaeological cremations and forensics. Still, few reference values are available that compare the mean weights for the different skeletal parts. In this paper we present new reference values for total skeletal weight, including the weight of the different skeletal bones based on a modern Portuguese Identified Skeletal Collection (CEI) curated in the Museum of Anthropology of the University of Coimbra (Portugal). The mean weight of the entire skeleton for the CEI pooled sample is 3323.8 ± 779.6 g. Sex and age differences were investigated. As expected, males display heavier bones, at a statistically significant level. The mean weight of the male skeletons is 3850 g, and 2797.6 g for the female sample. Age differences were found, especially for the female samples in the 29–39 versus 50–59 and/or >60 age groups, probably as a consequence of age‐related bone loss in post‐menopausal women. For the male sample, no clear age‐related trend was observed but for the unexpected result that the second highest bone weight recorded is in the oldest age group (>60 years). This could result from high mechanical loadings and thus greater bone robusticy and amount of cortical bone. The percentage of weight of the different parts of the skeleton was also calculated. These new values can be quite useful in the study of very fragmentary and/or commingled human remains, recovered from historic or forensic contexts, since the complete identification, by side, of the remains is not necessary.
