(Re)building the sacred landscape: Orleans, 1560 1610

The seizure and subsequent occupation of Orléans by theHuguenot forces in 1562–1563 and 1567–1568 was accompaniedby iconoclastic outbursts and the destruction of the religiouslandscape, which culminated in the demolition of the centraltower of the cathedral. This article examines the ways in whichthe religious and civic authorities reacted to this destructionand their attempts not only to bring about a renewal of thesacred landscape of the city but also to assert the importanceof Catholicism within that landscape. This was achieved againstthe background of the ongoing religious conflicts which wrackedFrance during the second half of the sixteenth century. Thearticle looks at how this was achieved not only through thereconstruction of the city's religious buildings but also throughthe use of religious rituals and sacred relics. Furthermore,a figure from the city's past, Jeanne d’Arc developedas a local cult symbolizing the triumph of Catholicism overthe Huguenots.     

Hydrogen isotope systematics of hair: archeological and forensic applications

The hydrogen isotope systematics of hair have been explored and several applications demonstrate the type of information that can be recovered from archeological and forensic hair samples. Experiment with modern hair demonstrate that sources of protein-based hydrogen in keratin are food and water. On the basis of a deuterium-enriched drinking study, it was found that 31% of hydrogen in human hair is derived from ingested water. At least 9% of total hydrogen in human hair is isotopically exchangeable with water or water vapor at 25 °C. Nearly complete exchange occurs in a matter of hours. The δD value of body water is approximately 17±10‰ (n=7) more negative than human hair, although there is much scatter in data for modern hair, which is clearly related to variability of the isotopic composition of ingested food and water. Archeological hair samples were analyzed from (i) a 370 year old Incan mummy sacrificed at 5300 m altitude in Argentina (Geoarchaeology 14 (1999) 27) and (ii) from a Woolly Mammoth from Siberia. High spatial resolution data along the length of hair from the mummy indicate seasonal variations in carbon, nitrogen and hydrogen isotope ratios. No hydrogen isotope anomalies are seen in the youngest hair at the base of the scalp, indicating that the individual probably lived at 1600 m, and spent less than a week at high altitudes before death. The mammoth also preserves a seasonal signal, suggesting hair growth rates of 33 cm/year, faster than human hair, but slower than horse tail hair. The limited isotopic range across seasons for the mammoth is consistent with a north-south migration on the order of 1000 km.     

A Flawed Saint: The Popular Image of William Gladstone in the Australian Colonies

ABSTRACT

This article looks at the popular image of William Gladstone which gradually emerged and evolved in the Australian Colonies throughout the nineteenth century. By using a wide variety of newspaper sources and political speeches, the piece shows how Gladstone was extensively discussed and interpreted on the far side of the ‘British World’. It tracks the ups and downs of the turbulent relationship Gladstone had with the Australian Colonies over his long career, as he influenced Australian history both directly through the policies he implemented and indirectly as an inspiration for local politicians. It concludes that although Gladstone repeatedly aggravated Australian opinion both through his time at the Colonial Office and the ‘soft’ foreign policy he pursued as Prime Minister, his domestic popularity as a successful liberal and democratic figure was enough to make him a hero in colonial eyes. This conclusion shows how ‘British World’ popular sentiment was able to trump nominal local interests. This demonstrates not only the predominance of Britishness in Australian identity during this time period, but also how as a simultaneously separate yet intimately linked part of the Empire, Australians abstracted their own significance and meaning from domestic British politics.     

Research design in digital luminance analysis

The prevalence of digital image analysis in studies spanning a wide range of fields makes the importance of set-up design decidedly important for repeatability and testing between studies, especially for those interested in the analysis of microscopic properties. This note outlines some important guidelines for setting up an image analysis protocol, and provides a case study based on the digital analysis of dental cement. Our method allowed for us (1) to get data through the conversion of optical luminance into numerical values and (2) to accurately measure image features through numerical analysis.     

Structural Determinism in the Interlocking World City Network

Taylor's interlocking specification of the world city network has offered researchers a theoretically informed way to measure the world city network using readily available firm location data. However, the number and size of firms that are viewed as linking cities to one another impose a form of structural determinism on the world city network. Specifically, when a relatively small number of firms is used to define a network among a relatively large set of cities, or when only larger firms are used, this approach is unable to reveal a wide range of structures features that may actually be present in the world city network it is intended to measure. Through a series of examples, I demonstrate how specific features of firm location data predetermine the structure, number and size of cliques, and density of world city networks derived using the interlocking approach. Concluding comments discuss the implications of this structural determinism by focusing on the case of the commonly used Globalization and World Cities data set 11, offer some suggestions concerning how the interlocking approach can be employed while avoiding structural determinism, and identify some alternative approaches to mapping the world city network. El modelo interconexión cerrada (interlocking) de la red mundial de ciudades (world city network) desarrollado por Taylor (2001) ha proporcionado a los investigadores un marco teórico para medir dicha red con datos fácilmente disponibles acerca de la localización de empresas. Sin embargo, el número y tamaño de las empresas que son consideradas como ‘vinculadoras’ (de ciudades) imponen una forma de determinismo estructural sobre la red. En concreto, cuando un número relativamente pequeño de firmas es utilizado para definir la red entre un conjunto relativamente grande de ciudades, o, cuando sólo se utilizan las empresas más grandes, este enfoque (interlocking) no es capaz de identificar o medir una amplia gama de características estructurales presentes potencialmente en la red de ciudades mundiales. A través de una serie de ejemplos, el autor demuestra cómo varias características específicas de los datos de localización de las empresas predeterminan la estructura, número y tamaño de los cliques y la densidad de las redes de ciudades mundiales resultantes de la aplicación de modelos de interlocking. Luego el autor presenta las implicancias del determinismo estructural mencionado, centrándose en el caso la base de datos de uso común GaWC # 11. Finalmente el articulo ofrece algunas sugerencias sobre cómo el enfoque de interlocking puede ser empleado sin caer en un determinismo estructural, y se identifican algunos enfoques alternativos para el mapeo de la red mundial de ciudades. 泰勒（2001）采用相对容易获得的公司地理位置数据提出的世界城市网络连锁度量方法,为研究者提供了一种理论途径。然而,将公司的数量和规模视为城市之间的联接是一种强加的世界城市网络结构决定论形式。特别是当用数量相对较少的公司或仅用大公司的数量来定义相对较大的城市网络集时,该方法不能揭示目前实际情况中大范围世界城市网络需要度量的结构特征。通过一系列的案例分析,本文显示了公司区位数据的特有特征预先决定了集团的结构、数量和规模,以及由泰勒的连锁方法推导出世界城市网络的密度。最后,通过曾被广泛采用的GaWC（全球化和世界城市）数据集的11个城市公司数据讨论了结构决定方法的应用,并就应用该方法如何避免结构决定论提出一些建议,进而识别一些可选用的方法来绘制世界城市网络图。     

Clintoncare and Obamacare: Lessons for Gridlock Theory

Abstract

The passage of the Affordable Care Act (ACA) in 2010 marked a significant achievement for congressional health reform. Despite increased partisanship, decreased productivity, and increased polarization of Congress, major health reform legislation was passed. We compare the ACA’s passage to the failure of Clinton-era health reform, emphasizing gridlock theory, which some scholars interpreted to predict that major health reform would not be possible in 2010. We identify several ways in which the different outcomes for the ACA and the Clinton reform effort can be explained by gridlock theory: pivotal actors, the gridlock window, and the status quo. However, factors not included in gridlock theory, such as the role of parties and institutional change, appear to also have contributed to the success of the ACA relative to the failure of Clinton health reform. Lessons learned from health reform suggest an opportunity to expand gridlock theory to account for these additional factors.     

Hydrothermal monitoring in a quiescent volcanic arc: Cascade Range,northwestern United States

Ongoing (1996–present) volcanic unrest near South Sister, Oregon, is accompanied by a striking set of hydrothermal anomalies, including elevated temperatures, elevated major ion concentrations, and ³He/⁴He ratios as large as 8.6 R_A in slightly thermal springs. These observations prompted the US Geological Survey to begin a systematic hydrothermal‐monitoring effort encompassing 25 sites and 10 of the highest‐risk volcanoes in the Cascade volcanic arc, from Mount Baker near the Canadian border to Lassen Peak in northern California. A concerted effort was made to develop hourly, multiyear records of temperature and/or hydrothermal solute flux, suitable for retrospective comparison with other continuous geophysical monitoring data. Targets included summit fumarole groups and springs/streams that show clear evidence of magmatic influence in the form of high ³He/⁴He ratios and/or anomalous fluxes of magmatic CO₂ or heat. As of 2009–2012, summit fumarole temperatures in the Cascade Range were generally near or below the local pure water boiling point; the maximum observed superheat was <2.5°C at Mount Baker. Variability in ground temperature records from the summit fumarole sites is temperature‐dependent, with the hottest sites tending to show less variability. Seasonal variability in the hydrothermal solute flux from magmatically influenced springs varied from essentially undetectable to a factor of 5–10. This range of observed behavior owes mainly to the local climate regime, with strongly snowmelt‐influenced springs and streams exhibiting more variability. As of the end of the 2012 field season, there had been 87 occurrences of local seismic energy densities approximately ≥ 0.001 J/m³ during periods of hourly record. Hydrothermal responses to these small seismic stimuli were generally undetectable or ambiguous. Evaluation of multiyear to multidecadal trends indicates that whereas the hydrothermal system at Mount St. Helens is still fast‐evolving in response to the 1980–present eruptive cycle, there is no clear evidence of ongoing long‐term trends in hydrothermal activity at other Cascade Range volcanoes that have been active or restless during the past century (Baker, South Sister, and Lassen). Experience gained during the Cascade Range hydrothermal‐monitoring experiment informs ongoing efforts to capture entire unrest cycles at more active but generally less accessible volcanoes such as those in the Aleutian arc.     

Evaluating the use of IKONOS satellite imagery in lowland Maya settlement archaeology

This article presents an extensive evaluation, in several contiguous or near-contiguous areas, of the viability of IKONOS satellite imagery in detecting sub-canopy Maya settlement in Peten, Guatemala. Initial research in and around San Bartolo, Guatemala, led to the conclusion that IKONOS imagery could be highly effective in detecting and predicting Maya settlement of the Preclassic and Classic periods, in zones of dense occupation near swampy lowlands known as bajos. The pioneering methods at San Bartolo are applied here to other regions in the Maya lowlands, but with mixed or unpromising results. Preliminary evaluation indicates that local climate, geology, hydrology, topography, pedology, and vegetation differ dramatically in these other regions, with consequences for wider application of the settlement signature discerned at San Bartolo. Possible reasons for these difficulties are offered in this paper, along with ways to strengthen the use of multispectral imagery in archaeological survey of tropical forests.
