Past agricultural responses to climate variability can helps us to better understand the current and future impacts of climate change on agricultural production. We studied rye (Secale cereale) and barley (Hordeum vulgare) yield responses to temperature fluctuations in Finland during the period 1861–1913. Our analyses demonstrate the high sensitivity of non-industrialised northern agriculture to temperature anomalies. We found evidence of a strong relationship between monthly and seasonal mean temperatures and crop yields. In particular, high spring temperatures were associated with higher yields. Additionally, we tested temperature-sensitive tree-ring series for their value in indicating previous agricultural outputs. The results imply that tree-ring proxies (in particular, maximum latewood density) can provide novel material for studies of historical periods and locations where instrumentally measured climate and harvest data are not available.

This talk consists of two parts - first part deals with what Jeffrey Bolster called “The Changing Nature of Maritime Insurrection”- and I will tie that into some research that I did on a New York clipper ship called the Contest. The second part of the talk will look at the rise of seafarer’s missions and that will tie Roald Kverndal’s magnum opus Seamen’s Missions: Their Origin and Early Growth into some research that I did on the earliest work done in New York among seafarers that pre-dated the American Seamen’s Friend Society.

La cuestión de la interpretación de Aristóteles por parte de la Academia alemana del siglo XIX es de interés tanto para filósofos como para economistas. Esto se debe a que el pensamiento clásico constituyó una cuestión de discusión e inspiración para el Idealismo, el Hegelianismo, el Historicismo y los economistas históricos alemanes (comenzando por Roscher) y su oponente austríaco, Carl Menger, fundador de la Escuela Austríaca de Economía. De este modo la filosofía antigua permaneció vigente. Al evaluar esta recepción, en este trabajo se muestra que el debate sobre entidades colectivas versus individualidad encuentra allí una base, y el individualismo metodológico, una justificación. Esto resulta útil aún hoy en el siglo veintiuno, en que presenciamos una crisis de la corriente principal de la economía.

The recent revolts of the middle class in the national capitals of the Philippines and Thailand have raised a new question about democratic consolidation. Why would the urban middle class, which is expected to stabilize democracy, expel the democratically elected leaders through extra-constitutional action? This article seeks to explain such middle class deviation from democratic institutions through an examination of urban primacy and the change in the winning coalition. The authoritarian regime previously in power tended to give considerable favor to the primate city to prevent it revolting against the ruler, because it could have become a menace to his power. But after democratization the new administration shifts policy orientation from an urban to rural bias because it needs to garner support from rural voters to win elections. Such a shift dissatisfies the middle class in the primate city. In this article I take up the Philippines as a case study to examine this theory.

Durante el s. XIX las bóvedas tabicadas se desarrollan enormemente, ampliando sus usos a nuevos tipos y extendiendose por zonas dónde no se habían utilizado tradicionalmente. Además, comienza a utilizarse el cemento como aglomerante en lugar del yeso. En este contexto se realizan muchos ensayos sobre ellas, con el objeto de validar un sistema que resultaba nuevo por estas razones. Se estudian a continuación una serie de ensayos de resistencia realizados en Francia entre 1837 y 1865, todos ellos sobre bóvedas de tamaño y geometría similar: entre 4 y 5 m de luz, y con flecha 1/10 de la luz, un tipo muy empleado en ese momento para la construcción de fábricas. El primero de ellos busca medir experimentalmente el empuje de una de estas bóvedas, para cerrar un debate sobre la existencia o no de empujes en las bóvedas tabicadas. Los siguientes quieren obtener la carga de rotura de las bóvedas, con el objeto de construir después unas similares.

From the late seventeenth to early nineteenth centuries, many religious temples have been built in the province of Alicante (south east of Spain) with brick domes as their main characteristic feature. Often, the limited data available about these remarkable constructions make rehabilitation interventions become into real research projects, with a high value for their historic conservation over time. The aim of this paper is to show a detailed refurbishment analysis of a religious temple built in 1778, showing the need of preservation of historic buildings as a part of the architectural heritage by establishing a common pattern of materials, geometry and constructive systems, specifically in their domes. In most cases, there was not an architectural project for the construction, that is why the analysis of any documentary and archival sources available is essential to find different ways to proceed on the use and maintenance of these religious buildings.

The Camposanto of Pisa is an extraordinarily complex and evocative monument, which has captured the imagination of pilgrims, both religious and secular, for centuries. The late Medieval and early Renaissance wall paintings that line the perimeter of the portico surrounding a vast inner courtyard, are unparalleled in early Italian art, not only for their striking variety of composition and narrative complexity, but also for the sheer grandeur of their proportion. However, the passage of time has scarred the structure of the Camposanto and inflicted terrible damage on its wall paintings. This thesis explores the material reality of the Camposanto as experienced over three centuries through the eyes of British travelers. In order to situate the Camposanto mural cycle within an historical and cultural context, the first chapter provides an overview of the construction and decoration of the monument. Notably, Giorgio Vasari (1511-1574), the Italian Humanist often recognized as the father of art history, included numerous descriptions of the Camposanto murals in his highly influential text Vite de' più eccellenti pittori, scultori, ed architettori. Accordingly, the second chapter provides an analysis of Vasari’s descriptions and reflects upon the influence that the Renaissance author may have had upon the subsequent British reception of the Camposanto murals. The third chapter utilizes three centuries of travel writing in order to investigate the aesthetic impact of the Camposanto mural cycle upon British tourists from the seventeenth through to the nineteenth century.
