Application of a new typological approach to classifying denticulate and notched tools: the study of two Mousterian lithic assemblages

Identifying tools by means of morphological attributes are widely used in lithic studies to categorize retouched artifacts from different archaeological periods. This procedure has facilitated the exchange of information between separate researchers and has improved the comparison of different assemblages. In these classifications, denticulates and notched tools have been regularly interpreted as analogues and chronologically unvaried in different and vast territories. Based on the definitions developed by Bordes, the denticulate category has become a catchall for any kind of tool bearing concavities. In this paper a new quantitative approach to the classification of denticulates and notched tools is proposed. The new methodology is based on measuring the length of notches and their distribution on the perimeter of the blank. Analyzing the lithic series of the Abric Romaní rock-shelter (Spain) and Grotta Maggiore di San Bernardino (Italy) led to the identification of 11 redundant forms: eight denticulates and three notched tools. Moreover, the application of Kuhn’s Geometric Index of Unifacial Reduction brought local manufacturing trends to light, calling into question the presumed geographical uniformity of these categories of artifacts.     

Deportation Discretion: Tiered Influence,Minority Threat,and “Secure Communities” Deportations

As deportations from the United States rose to unprecedented levels, a nationwide immigration enforcement program Secure Communities helped identify deportable noncitizens under arrest in county jails. Examining county‐level variation in deportation activity between 2008 and 2013, this paper contributes to immigration policy research by examining how county officials in some locations facilitated exceptionally restrictive deportation outcomes while others exercised the discretion to turn noncitizens over for deportation sparingly. Consistent with a hypothesized “tiered influence” relationship, but contrary to a “racial threat” hypothesis, Hispanic concentration predicts the highest levels of exercised discretion where Hispanic concentration is neither too small nor too large. Noncitizens under arrest seem to have benefited from above‐average Hispanic concentrations, except in counties where Hispanics exceed about 40 percent of the population.     

Consumption of Chinese goods in southwestern Europe: a multi-relational database and the vicarious consumption theory as alternative model to the industrious revolution (eighteenth century)

This article discusses the application of new technologies, software coding and computer analysis in the social sciences and humanities, mainly in the field of economic history. In the last two decades, the use of new computer technologies among historians to develop theories and solve questions has fostered a vibrant historiographical debate. However, these new digital tools have largely been used as an end in themselves, rather than as a means to develop hypotheses and answer questions. This has prevented researchers from fully exploiting such technologies in their field. In this article, I discuss how I designed a new multi-relational database using the “Access” package and SQL language to test the “industrious revolution” hypothesis and present the “vicarious consumption” theory as an alternative model for analyzing the eighteenth-century circulation of Chinese goods in the Western Mediterranean region. It presents the cross-referencing method I used to analyze the historical information I collected, mainly from probate inventories and trade records. This method makes it possible to navigate through the data in a way that goes beyond the traditional use of “excel” tables.     

Long-term land-use changes in small/medium-sized cities. Enhancing the general trends and local characteristics

Small and medium-sized cities represent the backbone of the European territory, promoting cohesion and an economic base for development. The study compares the spatial and temporal trajectories of land use in three small/medium-sized cities located in central Portugal, between 1958 and 2011. The cities of Viseu, Leiria and Castelo Branco were chosen because they are located in different urban sub-systems and because of the different factors that frame their alterations in land use, occupation and consequent urban development. The research evaluates the transformations, supported by indicators to explain the spatial dynamics of losses and gains and a principal component analysis compares the land-use trajectories for the three cities. The general results reveal an increase from the central part of the study areas to the periphery, contrasting with a continuous decrease of the agricultural parts, illustrating peri-urbanization and rururbanization processes. The study allows identification of the dynamics in the three analysed areas, highlighting the different rhythms of change and relating them to the particularities that exist in each city. The methodology represents an advantage for the analysis and evaluation of territorial dynamics related to land-use change, and made possible the identification of the different forces.     

Political Decoupling: Private Implementation of Public Policy

Where policy goals can be achieved through regulation of private firms, private provision of public services allows governments to separate public policies from their political costs by shifting those costs to the private sector. Over the past three decades, financial decoupling has emerged as a regulatory strategy for promoting conservation, especially in the energy sector. Decoupling refers to the separation of a firm’s revenues from the volume of its product consumed, which allows companies to pursue resource efficiency free from financial risk. Similarly, when private firms provide public services, they separate public policies from their political costs. This political decoupling allows governments to pursue controversial policies while avoiding their attendant political risks. Applied to environmental policy, this theory implies that potentially unpopular conservation policies are more likely to be adopted and succeed when implemented through private firms. As an initial test of the theory, we analyze California water utilities and their responses to that state’s drought from 2015–2017. Analysis shows that, compared with those served by local government utilities, private utilities adopted more aggressive conservation measures, were more likely to meet state conservation standards, and conserved more water.     

Action research for tourism planning in rural areas? Examining an experience from the Couto Mixto (Galicia,Spain)

This paper reviews a tourist planning experience developed for the Couto Mixto in 2007–2008. The Couto Mixto is a small territory of three hamlets situated in Galicia (Spain) and bordering Portugal that, until the end of the 19th century, used to be a virtually independent state of 25 km². This tourism planning process is compared and contrasted with the well‐described Action Research (AR) approach. The paper begins by providing the conceptual foundations of tourism planning which were used as a framework for the research. Then, the tourism planning experience is introduced in detail, focussing on the results of the interviews conducted to identify the tourism resources of the area. Therefore, 23 resources were inventoried and further audited to determine their various degrees of potential for the purposes of tourism planning. Previous AR experiences and the tourism planning initiative developed for the Couto Mixto share a common objective to facilitate change in communities in trouble. However, the case‐study tourism planning experience was not fully compliant with genuine AR in several respects. We conclude by recommending AR as a worthy approach for tourism planning as a way to effectively put the local community in focus.     

Experimental study of cut marks made with rocks unmodified by human flaking and its bearing on claims of ∼3.4-million-year-old butchery evidence from Dikika, Ethiopia

In order to assess further the recent claims of ∼3.4 Ma butchery marks on two fossil bones from the site of Dikika (Ethiopia), we broadened the actualistic-interpretive zooarchaeological framework by conducting butchery experiments that utilized naïve butchers and rocks unmodified by human flaking to deflesh chicken and sheep long limb bones. It is claimed that the purported Dikika cut marks present their unexpectedly atypical morphologies because they were produced by early hominins utilizing just such rocks. The composition of the cut mark sample produced in our experiments is quite dissimilar to the sample of linear bone surface modifications preserved on the Dikika fossils. This finding substantiates and expands our earlier conclusion that—considering the morphologies and patterns of the Dikika bone surface modifications and the inferred coarse-grained depositional context of the fossils on which they occur—the Dikika bone damage was caused incidentally by the movement of the fossils on and/or within their depositional substrate(s), and not by early hominin butchery. Thus, contrary to initial claims, the Dikika evidence does not warrant a major shift in our understanding of early hominin behavioral evolution with regard to carcass foraging and meat-eating.     

Archeoseismicity and environmental crises at the Sialk Mounds,Central Iranian Plateau,since the Early Neolithic

During the long-lasting cultural sequences of the Shurābeh and Sialk archeological mounds (6200–550 BC) the inhabitants encountered numerous diversified crises along a narrow fertile passageway at the edge of the Central Iranian Plateau Great Desert. Some of the threats may be attributed to earthquakes, drastic climatic changes, and man-made environmental deterioration, which possibly led to the settlement withdrawing at different stages toward a more suitable location. Our study identified the occurrence of a large-magnitude earthquake around 3800 BC along the Kāshān fault, which is well-documented by various lines of circumstantial evidence, including: (i) numerous contemporaneous smashed skeletons and artifacts underneath collapsed walls and ceiling debris in several different areas; (ii) tilted and collapsed walls; (iii) nearly N–S oriented fallen large storage jars; and (iv) nearly vertical deep ground fractures cutting walls and floors of the Sialk III₅ South Mound settlement. Archeological data also shows additional stratigraphic discontinuities and damages that may be attributed to earthquakes. However, damage features in limited exposed trenches are less conclusive and require additional careful excavations. Apparent ancient paleo-architectural innovative attempts to enhance the coherency/elasticity of the structures and minimize earthquake damage to buildings were also noted, suggesting the indigenous earthquake hazard mitigation endeavor. There seems to be a correlation between some site abandonment dates and possible drastic regional draught/cooling events. The natural and anthropogenic impacts addressed in this study constituted major threats to the sensitive archeological settlements at the fringe of the desert and the vicinity of the Kāshān active fault since antiquity.     

Regional Externalities And Growth: Evidence From European Regions*

Abstract. This paper models externalities of production across regional economies. Under the assumption that knowledge diffuses without political or administrative barriers, we derive externalities that affect the steady state and the process of growth of each economy. The empirical counterpart of the reduced form equation summarizing the process of growth allows us to test for the presence of regional spillovers and to measure their magnitude. Our results for a sample of European regions show that spillovers are far from negligible, are robust to the consideration of variables within each region, and may cause nondecreasing returns at the spatial aggregate level. The paper also relates previous empirical evidence on spatial dependence in growth studies to the externalities modeled here.
