From Aterian Notch to Aterian Tang: How to Make a Technological Invention

The Aterian lithic techno-complex that characterizes the late Middle Stone Age in North Africa is well known especially for its tanged or stemmed points. Recent techno-morphological and use-wear analyses have added new data to support the identification of the tang as the hafted portion of an artifact. They have also highlighted the presence of this attribute on tools other than projectile points, in contrast with the widespread idea that the tanged point is the Aterian fossile directeur. The design of this specific device, the tang, for hafting purposes is regarded as a great technical innovation that underlines a modern behavior. Our work provides new use-wear and experimental data, aiming at discussing the cognitive preconditions of this technical innovation that could have originated from a specific functional unit: the notch. Notches are quite abundant in the Aterian techno-complex. Our systematic study of this tool category from Aterian sites of the Jebel Gharbi allowed defining the notch per se as a techno-morpho-functional unit that was “applied” to different types of blanks, including “reused blanks,” which show a heavy patina on their surface. This functional unit has been used for various types of activities and can be found either alone on a blank or with multiple other units on the same blank, creating different tool morphologies. According to this interpretation, the tang could have been considered by Aterian populations as a new resulting variant of various possible combinations of notches, for defining and/or transforming the shape of a tool.     

A Comprised Archaeological History of Taiwan through the Long-Term Record of Heping Dao,Keelung

We present the results of six years of archaeological work carried out in Heping Dao, Keelung, northern Taiwan. The site has revealed a rich archaeological record spanning a sequence that comprehends most of the history of Taiwan, including the most salient historical landmarks in it. The study of this long-term sequence of habitation in Heping Dao throughout prehistory to current times, allows us to attempt a historical archaeology of the longue duree of the place that in turn enables the establishment of comparisons between periods and raising of specific questions, among them: the general understanding of cultural transformation along the Neolithic and the Iron Age, and in turn the transition Iron Age/Aboriginal historic times in Taiwan, which in our view has to be observed as a history of continuity rather than of interruptions; the recognition of the Chinese presence in Taiwan in the pre-European period; the implantation of the European colony and its effects on the local populations; the differing material remains and impacts caused by the presence of pre-European Chinese and the Qing occupation; and the potential for a comparison between the European and the Japanese colonial projects as seen in the material record.     

Economic and Environmental Policy Analysis of the Flumen‐Monegros Irrigation System in Huesca,Spain

This article describes a behavioral model of the Flumen‐Monegros irrigation area (Spain) and presents the results from the model simulation under various policy scenarios. The model combines agronomic, economic and policy information in a framework built using linear programming and crop growth simulation techniques. An important feature of the model is the classification of crop acreage in various types of soils which have different productive potential. The objective function maximizes net margins of crops and includes direct payments of the Common Agricultural Policy (CAP). The crop activities covered in the model are the main crops cultivated in the area (fallow, wheat, barley, corn, sunflower, alfalfa, rice, other crops, and CAP set‐aside). To validate the model, the results on cropland utilization obtained from the model have been compared with actual cropland utilization, concluding that the model closely approximates the actual data. The model is used to characterize the behavior of the irrigation area under three scenarios which reflect likely changes in agricultural and environmental policies: removal of direct payments, increase in water prices, and reduction of fertilizer use. The results show the large impact of these three scenarios on farmers' production decisions: the elimination of direct payment reduces net margin almost by half; prices corresponding to full recovery of water costs reduce significantly the cultivated acreage; and the reduction in fertilizer use causes a fall of 23 percent in net margins.     

Determinants of Residential Location Choice: How Important Are Local Public Goods in Attracting Homeowners to Central City Locations?*

Abstract. A hybrid conditional logit choice model is estimated using data on the characteristics and destination of homeowners who engaged in intrametropolitan moves among 17 school districts within the Columbus, Ohio area in 1995. The model is used to test the relative influence of local fiscal and public goods versus household‐level characteristics in determining household location choices across central city and suburban school districts. Results provide evidence of both a “natural evolution” of households to the suburbs, due to job location, residential filtering, and household income and lifecycle effects, and “flight from blight,” due to lower school quality, higher crime levels, and lower average income levels in the city. In comparing the magnitudes of these variables, we find that school quality exerts the strongest influence: a 1‐percent increase in the school quality of the city district increases the probability of choosing a city residence by 3.7 percent. In contrast, the effects of household income and other individual characteristics are relatively modest. The findings provide support for a “flight from blight” suburbanization process that is dominated by differences in neighborhood quality between the city and suburbs. An implication is that investments that promote central city development and reduce suburbanization are justified on efficiency grounds if negative externalities are generated by increased concentration of poverty, crime, and low school quality.     

Women’s representation and participation in UNESCO heritage discourse

ABSTRACT

Gender equality represents one of the most challenging objectives in contemporary society and has become a priority for UNESCO (Medium-Term Strategy 2008–2013 and 2014–2021), as it is considered ‘an essential part of the equation for more inclusive and sustainable development’. However, in various World Heritage sites, women are still being marginalised from decisional processes concerning the identification and interpretation of the past and they are often underrepresented in the main narratives. Using the case study of the World Heritage Vineyard Landscape of Langhe-Roero and Monferrato (Italy), I explore how international and national documents frame gender equality in order to uncover underground power dynamics that risk undermining cultural representation and participation. Through the analysis of the interviews done with a group of local female wine producers, I compare heritage discourses with the perception women have of their contribution in the identity and heritage-building process. If dominant heritage discourses are characterised by a rather male-driven set of values, could lack of women’s representation influence the activation of their participation? Are women willing to participate in the management of a heritage which has not been recognised through their values and meanings? What kind of participation would they desire?     

Mycenaean shipwright tool kit: its reconstruction and evaluation

The present study aims to answer questions of utility and efficiency, on the basis of archaeological evidence, of the nominated Mycenaean shipwright tool kit through experimental methods. The target set was established through the recording of archaeological data, examination of the available findings, classification of the finds, gathering of the relevant sources (literature, iconography, archeological parallels and preserved traces), reconstruction of the findings (casting, elaboration of the metallic parts and reconstruction of the hafts), usage of the reconstructed tools and the evaluation of them qualitatively, quantitatively and ergonomically via the reconstruction of a segment of the Uluburun shipwreck hull. Knowledge of tool production of the Late Bronze Age has been furthered. Questions on the casting of the metal parts of tools and the elaboration of their different parts have been answered. The reconstructed tools appear suitable for use in pegged mortise-and-tenon joinery in shipbuilding by skilled woodworkers. Moreover, the reconstructed tools proved to be user friendly. Experimental methods proved useful in the allocation of efficient criteria for the use-based classification of tools. Functional differences between the tools were shown, and questions on utility were answered. The Late Bronze Age shipwright, as master of his craft and tool use, could make new tools or adjust them to the demands of a particular job, as well as to his own body build. The range of tools used for shipbuilding in the Late Bronze period is comparable to those used today.
