Using provenance data to assess archaeological landscapes: an example from Calabria, Italy

Ceramic provenance studies have helped archaeologists examine trade and exchange in multiple scales, the organization of production, and even vessel function. Yet, they may go even further, to provide a venue for the examination of past people’s perception of their landscape. To do so, a methodology is needed that links the choices prehistoric potters made, as reflected in their ceramics, with the choices their landscape could afford them, as reflected in the extent and distribution of local clays, and the physical, chemical and mineralogical characteristics of these clays. Using the region of Bova Marina in southwestern Calabria as a case study, we have combined a raw materials survey with field and laboratory experiments, along with chemical and mineralogical analyses of the collected sediments to understand the distribution and the physical, chemical and mineralogical variability of locally available clays and provide baseline data against which prehistoric ceramic materials from the region may be compared. We show that the local sediments can be divided into three major units, based on their macroscopic, mineralogical and chemical characteristics, that correspond well with the major geological units outcropping in the study area. While two of these units have internally consistent properties, the third is variable.     

The Science of Empire: Darwinism,Human Diversity,and Russian Physical Anthropology

Summary : The article explores deployment of the Darwinian narrative of the “natural history of humanity” in Russian physical anthropology in the late nineteenth to the early twentieth century. It traces two narratives developed by the leading Russian school of physical anthropology: one narrative advanced a universalist vision of collective scholarly enterprise working toward clarifying the missing links in the a priori accepted developmental evolutionary model. The other constructed a new language that undermined the idea of species/subspecies/races/nations/ as stable, externally bounded, and internally homogeneous units and attempted to rationalize imperial hybridity. The article's main focus is on the latter classificatory narrative, its relational methodology, and the protostructuralist units of comparison that it produced.

Maximising Response Rates in Mail Surveys

Many studies in geography and other disciplines require data to be collected from human subjects. Survey techniques are routinely employed but as expense and time impose powerful constraints there is much interest in methods of making the data collection process as efficient as possible, particularly when the numbers of subjects involved are large. The surveys described here were conducted to collect data for a study of residential water use in Melbourne. A previous analysis of demographic. physical and economic data (Aitken et al., 1991) had revealed the need for additional data to be used in explaining variability in residential water consumption. A theoretical basis was established for the relevance of attitudes, habits and values to water use, and a survey was planned with the primary aim of measuring these psychological constructs. It was conducted in early 1991. and the water consumption of participating households was recorded over winter of that year. The survey instrument also targeted demographic and physical data relevant to water use in the home. Dillman's Total Design Method (TDM — Dillman, 1978) offers an integrated and detailed methodology for survey design. and it was from the TDM that most of the methods for these surveys were derived. The elements of Dillman's methodology most relevant to these surveys are those concerning the presentation of the questionnaire package and its distribution.

Physical planning in an era of marketization: conflicting governance perspectives in the Swedish Transport Administration

Planning of transport infrastructure in Sweden has undergone successive legislative changes as well as neoliberal corporatization and marketization reforms in recent years, with a general aim to increase efficiency and effectiveness. This paper presents planning practitioners’ experiences of far-reaching marketization of physical planning practice in line with a strategy within the Swedish Transport Administration (STA) to become a ‘Pure Purchaser’. The strategy implies that all practical planning work should be carried out by procured consultants. The paper follows a qualitative, explorative approach based on document studies and interviews with practitioners actively involved in carrying out physical planning of road and rail investments. The concept of ‘modes of governance’ is applied to highlight and analytically interpret differences in perspectives on efficient and effective governance as expressed in the planning legislation, and the STA marketization strategy, respectively. The empirical results make evident that the recent marketization reforms are generally perceived as strongly and negatively affecting the efficiency and effectiveness of planning practices while also circumscribing professional discretion. The study highlights the importance of specific organization and management perspectives as explanatory factors in studying efficiency and effectiveness of planning practices.     

A Geostatistical Linear Regression Model for Small Area Data. 一种适用于小区域数据的地统计线性回归模型

We present a new linear regression model for use with aggregated, small area data that are spatially autocorrelated. Because these data are aggregates of individual‐level data, we choose to model the spatial autocorrelation using a geostatistical model specified at the scale of the individual. The autocovariance of observed small area data is determined via the natural aggregation over the population. Unlike lattice‐based autoregressive approaches, the geostatistical approach is invariant to the scale of data aggregation. We establish that this geostatistical approach also is a valid autoregressive model; thus, we call this approach the geostatistical autoregressive (GAR) model. An asymptotically consistent and efficient maximum likelihood estimator is derived for the GAR model. Finite sample evidence from simulation experiments demonstrates the relative efficiency properties of the GAR model. Furthermore, while aggregation results in less efficient estimates than disaggregated data, the GAR model provides the most efficient estimates from the data that are available. These results suggest that the GAR model should be considered as part of a spatial analyst's toolbox when aggregated, small area data are analyzed. More important, we believe that the GAR model's attention to the individual‐level scale allows for a more flexible and theory‐informed specification than the existing autoregressive approaches based on an area‐level spatial weights matrix. Because many spatial process models, both in geography and in other disciplines, are specified at the individual level, we hope that the GAR covariance specification will provide a vehicle for a better informed and more interdisciplinary use of spatial regression models with area‐aggregated data.     

REGIONAL DEVELOPMENT,ECONOMIC ACCOUNTABILITY,AND SOCIAL JUSTICE

The author argues in favor of redoubled efforts at improving access to transportation and communications as the most effective means of government intervention promoting a “level playing field” for disparate territorial units under “regional khozraschet.” He maintains that such an approach does not remove incentives for innovation and productivity at individual enterprises, but helps eliminate the disadvantages of peripheral production enterprises relative to those of “central” areas. A scheme is proposed whereby increasing overall (intermodal) transportation accessibility would be the objective, rather than maximizing narrowly based microeconomic efficiency criteria for various transportation ministries.

Regional Occupational Employment Projections: Modeling Supply Constraints in the Direct‐Requirements Approach*

Detailed industry‐occupation employment forecasts are an important class of regional labor market information produced by the U.S. Bureau of Labor Statistics. In theory, the forecasts should improve the national, interregional, and intertemporal matching efficiency of labor markets. But the efficiency argument is dependent on the quality of the forecasts. The methodology used to produce the projections is still fundamentally a demand‐requirements approach that implicitly assumes that labor supply is infinitely elastic for every occupation. This paper examines the validity of that assumption and evaluates a demographically based labor supply module as an adjunct to the current methodology.     

Comparing Axe Heads of Stone,Bronze, and Steel: Studies in Experimental Archaeology

Abstract

This paper presents inferences based on the results of an experimental project comparing the effectiveness of stone, bronze, and steel axes in felling trees. The study shows that bronze is as efficient as steel for this task, and therefore the two material types can be considered equivalent when comparing technologies. We support the findings of other studies indicating that metal axes are more efficient than stone axes in a number of ways other than effort expended. Other variables that affect tree felling efficiency are discussed. Tree type, tree diameter, and axe type are the most important, but other factors may also be significant. The use of regionally specific estimates for tree felling time is suggested when making cultural inferences based upon experimental data.     

Improving the learning processes of Physical Geography through the use of landscape photographs in class

The use of alternative teaching methods to lectures is one of the keys to develop a more participatory and effective education. In the teaching of Geography, greater interaction of students with elements of the landscape through the active use of photography could be one of the ways to achieve this efficiency. This article describes an experiment conducted in 2016 with students of the subject Physical Geography of the Iberian Peninsula. Two different teaching methodologies were applied to two groups of students. The first one was based on dividing the time of each class between participatory comments of landscape photographs and imparting theoretical knowledge through lectures. The second methodology consisted only of lectures, following a more traditional approach. Additionally, some students from the first group actively participated by uploading and tagging their own field pictures to a photographic repository of the University of Seville. The effectiveness of the different activities in each group was assessed through four tests, performed monthly. The results indicate that the use of landscape photographs as a participative teaching resource allows a more efficient learning of theoretical concepts. Therefore, the proposed methodology should be considered by those interested in improving the quality and effectiveness of their teaching of Geography.     

Simple Seismic Assessment of Traditional Unreinforced Masonry Buildings

A framework for quick seismic assessment and retrofit of traditional unreinforced masonry (URM) structures is presented. The proposed methods build on simple principles of structural dynamics and are used as an alternative to detailed time-history analysis, in recognition of the prevailing need for simple and practical methods, compatible with the low-budget and the limited level of knowledge regarding materials, internal force paths, connectivity and condition of older URM structures. An objective is to identify areas in the building that are particularly susceptible to damage and for guiding the types of the required global interventions to improve seismic response. Demand and supply are expressed in terms of relative drift ratios that quantify the intensity of out-of-plane differential translation and in-plane shear distortion of masonry walls. A characteristic traditional building type of timber-laced masonry is used as a model structure for illustration of concepts. The morphology and geometry of the building correspond to a statistical sample of the actual traditional unreinforced masonry buildings (TURM) found in historical centers of many towns in the greater region of Northern Greece. The methodology is particularly useful for setting retrofit priorities and management of the collective seismic risk of historical entities.     

REVISITING LITHIC SCATTERS: A CRM PERSPECTIVE

Abstract

The scope of an archaeological survey may be defined by environmental or cultural boundaries, or by arbitrarily defined boundaries, which is generally the case in cultural resource management (CRM) surveys. The most common site type encountered during the course of almost any Phase I CRM survey is the temporally nondiagnostic “lithic scatter.” The majority of surveys conducted within the United States today are compliance driven, and thus most lithic scatters are discovered and recorded by CRM firms. They are therefore investigated according to state standards, and their potential for contributing to the archaeological record is evaluated according to criteria established under the National Historic Preservation Act. Under these circumstances, the significance of the vast majority of these sites is dismissed outright during the course of initial investigation and reporting. While nondiagnostic lithic scatters may often be uninteresting as individual units of analysis, this paper argues that in aggregate they represent a vital component of the archaeological record. It further argues that their potential value as individual units of analysis is often dismissed too casually. The paper demonstrates that under currently accepted field methodology, many of these sites are not adequately investigated and are not entered into any meaningful database. Recommendations for improving the initial investigation and interpretation of these sites are offered, based on recent initiatives taken in Louisiana by the U.S. Forest Service on Kisatchie National Forest.     

The Efficiency of Social and Economic Image Projection in Spatial Configurations

In this paper we examine issues related to the regional images of spatial configurations and their performance in attracting resources that are expressed in terms of regional gross domestic product. The concepts of social and economic image efficiency are introduced and their dual relationship is acknowledged. A non-parametric frontier analysis methodology is proposed for assessing the two types of efficiency, based on the concept of data envelopment analysis. The method is applied to the twenty prefectures of Northern Greece on data that span the period 1981 to 1991.     

TAX AND FINANCIAL POLICIES FOR THE HOUSING MARKET OF THE 1980s

The imbalance in the age structure of the U.S. population has created conditions for heavy demand and consequently pressures for rising relative prices in the market for owner-occupied single family housing in the 1980s and 1990s. Working in reverse, the unbalanced demographics may well lead to the falling relative price of housing around 2010, the period in which the baby boom generation will be retiring and may wish to liquidate its housing investment. Changes in housing policies during the 1980s could help offset the anticipated costs associated with the swings in demand pressures in the housing market over the next forty years. Current favorable tax and financial policies toward homeownership encourage both the overconsumption of housing and the overinvestment in housing as a retirement asset. Tax and financial policies could be changed to neutralize the attractiveness of owner-occupied single family units relative to alternative types of housing units. To avoid overbuilding for the future, policies could encourage the efficient use of existing housing resources through intergenerational turnover, upgrading of units and neighborhood improvement, and condominium-style conversion of multiunit structures from rental to owner-occupancy. Finally, tax and financial policies toward investment could encourage the baby boom generation to diversify its retirement assets outside of housing.

ALLOCATIVE EFFICIENCY OF RURAL NEVADA WATER SYSTEMS: A HEDONIC SHADOW COST FUNCTION APPROACH*

ABSTRACT. The efficiency of the water utility firms in rural Nevada and their input optimization are examined in this study. The empirical methodology incorporates a hedonic specification of the nonminimum globally concave cost function in estimating the effect of the regulatory environment and the quality of water services on the optimum utilization of inputs. Allocative distortions are introduced through shadow prices and are specified as functions of regressors which make distortion factors firmand input-specific. The results show that 76 percent of the water utilities of rural Nevada in the sample overutilize energy relative to labor. The impact of allocative distortions on each firm's cost is also computed.     

Local and more local: Impact of size and organization type of settlement units on candidacy

Following current debates on the study of the quality of local government, this article focuses on the effects of settlement unit size and organizational type on candidacy in local elections within the Czech Republic. Municipal size and institutional design are traditionally seen as important factors influencing political participation at the local level. However, citizens in differently defined settlement units included in a municipality are disadvantaged differently by these factors and thus, de-motivated to participate in politics. The unit of analysis within the article is a settlement unit within a municipality. The article uses Poisson regression to estimate the effect of the absolute and relative size of the settlement unit and different organizational types of settlement unit on the relative number of candidates in the unit. The analysis is based on data from 6,124 Czech municipalities over three sets of elections. The results of the analysis show that increasing absolute size and decreasing relative size of settlement unit have negative effects on the number of candidates in units. Also the institutionally disadvantaged units (defined by the location of the municipal office within the settlement unit) produce smaller number of candidates. The results show the importance of structural factors on the traditionally neglected type of political participation (candidacy) within this field. This allows the formulation of recommendations for local government reforms, not only in the Czech Republic, but also for amalgamated municipal systems.     

An Impact Analysis of the European Structural Funds on the Variation of the Rate of Employment and Productivity in Objective 1 Regions

Regional policies seek to enable regions to increase their competitiveness and development, and as such one priority Objective of activities financed by Structural Funds is higher employment, higher productivity and economic activity. How efficiently the regions apply the funds is a fundamental issue for the development and continuity of regional policies. We therefore consider that determining the efficiency of European regional policies is an issue of high importance, and this is the main aim of this study. We have considered it appropriate to use the available information to apply a mathematical technique known as Data Envelopment Analysis (DEA), which allows us to calculate the technical efficiency and inefficiency of the Structural Funds applied in the Objective 1 regions for the period 2000–2006. Furthermore, we wish to determine if the regions have been more efficient in creasing their levels of employment or in increasing productivity. Our study applies this methodology along with other methods like regression analysis, profit analysis and factorial analysis to determine the variation in the rate of unemployment and productivity in these European Regions. The study reveals that only eight regions are efficient, although none of them is run in all the models.
