A Workshop on European Peasants

Art critics and scholars have puzzled over the behavior of Pablo Picasso, Gerhard Richter, and Sigmar Polke, three important modern painters who have made frequent and abrupt changes of style. In each case, assuming this behavior to be idiosyncratic, the experts consequently failed to recognize its common basis. But stylistic versatility is in fact often a characteristic of conceptual innovators whose ability to solve specific problems can free them to pursue new goals. This contrasts sharply with the practice of experimental artists, whose inability to achieve their goals often ties them to a single style for an entire career. The phenomenon of the conceptual innovator who produces diverse innovations is an important and new feature of twentieth-century art; Picasso was the prototype, and he has been followed by a series of others, from Marcel Duchamp and Francis Picabia to Bruce Nauman and Damien Hirst. Versatility has furthermore been a characteristic not only of modern painters but also of conceptual innovators in other arts, and of conceptual scholars. Recognizing the common basis of this behavior deepens our understanding not only of twentieth-century art but also of human creativity more generally, for it adds a dimension to the contrast between conceptual and experimental innovators.     

Between Large-N and Small-N Analyses: Historical Comparison of Thirty Insurgency Case Studies

Abstract

The authors study the 30 insurgencies occurring between 1978 and 2008 using four methods crossing the qualitative/quantitative divide. The four approaches are narrative, bivariate comparison, comparative qualitative analysis, and K-medoids clustering. The quantification of qualitative data allows the authors to compare more cases than they could “hold in their heads” under a traditional small-n qualitative approach, improving the quality of the overall narrative and helping to ensure that the quantitative analyses respected the nuance of the detailed case histories. Structured data-mining reduces the dimensionality of possible explanatory factors relative to the available observations to expose patterns in the data in ways more common in large-n studies. The four analytic approaches produced similar and mutually supporting findings, leading to robust conclusions.     

Railways as a Factor of Change in the Distribution of Population in Spain, 1900–1970

Abstract

The central focus of this work is to test a new methodology to measure the impact of the railway on the distribution of population, in this case in Spain. To achieve this, it was necessary to previously integrate data relating to population and railway lines into a geographical information system. The result was a spatial database that includes population data from homogeneous census series obtained for the municipal scale and the evolution of the railway network in service at corresponding points in time. This allowed the authors to apply spatial-temporal analysis. By so doing, this work constitutes an analysis of a new methodology, as they used exploratory spatial data analysis and geographically weighted regression to detect spatial patterns and estimate the influence of the railway and distance from the coast on population change. The results obtained show that the influence of the railway was very pronounced in some areas, while in others it was just one of the factors that could explain major changes in population distribution.     

Range of motion and energy cost of locomotion of the late medieval armoured fighter: A proof of concept of confronting the medieval technical literature with modern movement analysis

ABSTRACT

Study of technical, normative, and narrative medieval literature and of archaeological pieces allows the motor skills of armoured members of the aristocracy to be outlined but not quantified. The authors present novel data on the impact of wearing armour on both the freedom of movement and the energy cost of locomotion, and confront the results to systematic analysis of medieval written sources. An accurate harness replica realized in an informed archaeological experimental way, close to medieval material and manufacturing conditions, was used for the experiments. Measurements of the energy cost of locomotion in and out of armour were taken during walking and running on a treadmill. Gait analysis and range of motion of joints were performed with 3-D kinematics. The results indicated an increase in the energy cost of locomotion in slight excess to the added weight and for most movements studied reductions in the range of motion over the joint, potentially to the advantage of the wearer during combat. This proof of concept appears promising for further study in this field of scholarly endeavor.
