Experimental Heating of Moravian Cherts and its Implication for Palaeolithic Chipped Stone Assemblages

The applicability of colour, magnetic susceptibility and remanent magnetization measurements for the identification of heated or accidentally burned Palaeolithic cherts from Moravia (Czech Republic) is tested in this study. We conclude that all these methods are usable. Colour changes are best detectable in materials heated at between 250–350°C, while magnetic susceptibility and remanent magnetization change at higher temperatures, closer to 600°C. This latter temperature, however, is usually destructive for cherts and is probably evidenced by accidentally burned artefacts. With the use of the three methods, we managed to identify three probably heated chert artefacts from two early Upper Palaeolithic assemblages from Moravia.     

Full‐Vector Archaeomagnetic Dating of a Medieval Limekiln at Pinilla Del Valle Site (Madrid,Spain)

Archaeomagnetic dating based on the full geomagnetic field vector was carried out on a limekiln excavated at Pinilla del Valle archaeological site (Madrid, Spain). The limekiln tradition in this area is largely documented by historical sources for recent centuries but the date of the studied kiln's last use was unknown. The combination of mean archaeomagnetic directional and absolute archaeointensity results shows that the kiln was last used between ad 1296 and 1413, in good agreement with two independent radiocarbon dates. This study provides the first archaeomagnetic evidence that the local limekiln tradition dates back to at least late medieval times. Furthermore, the inclusion of these data in the Iberian secular variation curve and geomagnetic field models will help to improve the archaeomagnetic dating technique.     

Was He Murdered or Was He Not?—Part II: Multi‐Elemental Analyses of Hair and Bone Samples from Tycho Brahe and Histopathology of His Bones

Hair and bone samples procured from the remains of Tycho Brahe were analysed by several analytical techniques. In segmented hair samples, concentrations of Fe, As, Ag and Au at the tips exceeded values for the contemporary population; however, they decreased towards the hair bulbs, similarly to Hg, indicating that recent exposure that was discontinued ~2 months prior to Brahe's death. Several other elements did not follow this pattern. Analyses of bones revealed signs of long‐term exposure to Au, while many other elements were within expected ranges. Histopathological examination of bone sections yielded no signs of severe bone metabolic disorders.     

Magnetic Alteration of Soils by Late Holocene Hunter–Gatherer Groups (Tierra Del Fuego,South America)

The present work aims to analyse the magnetic signature from the Late Holocene open‐air archaeological deposits of hunter–gatherer ephemeral occupations. For this purpose, two profiles were sampled at the Marazzi 2 site in the north‐western Isla Grande de Tierra del Fuego, Chile, in order to carry out studies of magnetic susceptibility, hysteresis cycles, back‐field remanent magnetization, isothermal remanent magnetization and thermal variation of magnetic susceptibility at high and low temperature. Despite short‐term occupations, the P1 profile shows a magnetic peak at a depth of ~30–70 cm due to magnetite, probably formed by anthropogenic activity related to combustion. The P2 profile instead yields an anomalous peak of coercivity (at a depth of 20–40 cm), which could also be anthropogenic, due to the presence of finely dispersed ancient ‘red ochre’. The red ochre is proposed to form anthropogenic thermal alteration of goethite associated with volcanic ash, the remnants of which were found in thin sections from the P2 subsoil.     

Persistence of Crime Hot Spots: An Ordered Probit Analysis

The temporal persistence of crime hot spots is recognized as a valuable indicator of consistent problem areas. The current literature has not adequately addressed the mechanisms that perpetuate or interrupt persistent crime hot spots. Investigating the persistence of violent crime hot spots in Columbus, Ohio, from 1994 to 2002, this study fills a gap in the literature by identifying neighborhood structural correlates that drive the persistence of hot spots. Specifically, this study identifies yearly crime hot spots, and estimates an ordered probit model to explore the neighborhood structural determinants. The results indicate that socio‐economic factors, identified from a synthesis of social disorganization theory and routine activity theory, significantly correlate with persistent patterns of violent crime hot spots. This gives evidence that a combination of the two ruling spatial theories of crime provides an applicable framework for understanding the temporal dimension of violent crime hot spots. By identifying the factors that contribute to the persistence of hot spots of crime, insights gained from the results can help to inform focused crime prevention efforts.     

ZONING A CROSS‐BORDER CITY

This paper investigates zoning in a cross‐border linear city that consists of two bordering towns. In each town, a local regulator has a say in the location of the local firm. We find that local regulators may use zoning strategically. The incentive to gain consumers from the other town, or not to lose local consumers, may push regulators to approve only locations for firms close enough to the frontier. When zoning is costly an asymmetric equilibrium may emerge: only one regulator resorts to zoning. In the case of towns of different sizes, the regulator of the larger town is the only one that zones in an asymmetric equilibrium.     

How do Migrant Workers Respond to Labour Abuses in “Local Sweatshops”?

This article aims to provide empirical evidence on understanding how migrant workers’ responses to labour exploitation in low‐wage economies are articulated. Inspired by the low levels of conflict among workers in small urban sweatshops in Italy and Argentina, we ask ourselves what contextual and subjective factors prevent workers from organising collectively. Here we argue that in order to understand the nature of their responses, it is necessary to consider not only the organisation of the labour process, but also the class divisions within migrant communities. We also bring in briefly the role of the state in (mis)regulating migrant labour exploitation. We conclude by showing that workers’ responses are highly individualised and that community leaders with economic interests in sweatshop economies may play a role in securing their continuation by channelling the workers’ responses towards the defence of the “ethnic economy”.     

Remembering the German Past in the Czech Lands: A Key Moment Between Communicative and Cultural Memory

The objective of this paper is to document the ongoing shift from communicative to cultural memory of war and post-war events in the Czech Republic by using an example of a local struggle about a memorial for German inhabitants of a Czech town killed in June 1945. Thanks to an anthropological and social geographical approach based on interviews, family memory research, observations, and analysis of archive materials, it is possible to reconstruct the local and international sources of the post-1989 collective memory of the German past in Central Europe. This memory is still in constant conflict with the pre-1989 version of Czech national history which had contemptuously marginalized its German component. The communicative memory of the German past has entered the public space and tries to become a permanent part of the Czech cultural memory, but it is not a straightforward process, mainly due to the continuously strengthening nationalistic framing of memory within Central Europe.     

Rewriting the Latin liturgy of the Holy Sepulchre: text,ritual and devotion for 1149

ABSTRACT

An extraordinary reform of Jerusalem’s liturgy took place under the patriarchate of Fulcher of Angoulême (1146–57). The refocusing of Jerusalem’s rite positioned the commemoration of Easter as its central theological theme. This was effected to a level unparalleled in the liturgical traditions of the West. However, rubrics from extant twelfth-century liturgical books from Jerusalem further reveal how this reform was made to coincide with the 1149 rededication of the Church of the Holy Sepulchre, and the 50-year celebration of the capture of Jerusalem. From this newly discovered perspective, this study argues that liturgy, through its active rewriting, formed an integral part of a hitherto unexplored religious programme carried out by Patriarch Fulcher. Liturgy, alongside architecture and civic festivities, was used as a central tool to reshape the devotional identity of Jerusalem and the Latin East.     

Reassessment of Neovenericor Rossi de García,Levy & Franchi, 1980 (Bivalvia: Carditidae) using a geometric morphometric approach,and revision of planicostate carditids from Argentina

Pérez, D.E., Alvarez, M.J. & Santelli, M.B., July 2016. Reassessment of Neovenericor Rossi de García, Levy & Franchi, 1980 (Bivalvia: Carditidae) using a geometric morphometric approach, and revision of planicostate carditids from Argentina. Alcheringa 41, xxx–xxx. ISSN0311-5518.

Various systematic approaches have been applied to the Neogene planicostate carditids of Patagonia. Some authors have included these species within Venericor (known from the Eocene of North America and Europe) or in Megacardita (recorded from the Miocene of Europe). By contrast, Rossi de García et al. erected the endemic Neovenericor in 1980 for Patagonian species. The three proposed genera have variable outlines and similar hinge teeth configuration. Two geometric morphometric analyses were performed, which included the type species of the following taxa: M. jouanneti (middle Miocene, Mediterranean Basin), V. planicosta (middle Eocene, Paris Basin) and N. austroplata (early Miocene, Chenque Formation, Chubut Province). In the first approach, an Elliptic Fourier Analysis was used to test the general variability of outlines. In the second, a landmark-based method was employed to analyse the hinge configuration, followed by a Discriminant Function Analysis. The outline analysis discriminated Megacardita from the other two taxa based on its more elongate and rectangular shells. The Landmark Analysis distinguished the three taxa based on both, left and right hinges. The Discriminant Function Analysis showed significant values for this differentiation. Neovenericor has a higher hinge plate, broader and less posteriorly inclined teeth, and a less sinuous ventral edge than Megacardita; and it has larger and more posteriorly inclined teeth than Venericor. Other morphological characters of the genus include an intermediate number of radial ribs that do not dissipate ventrally, and wide and deep intercostal spaces. Thus, Neovenericor is clearly a distinct taxon. All Argentinian planicostate carditids were revised and included in this genus because they embrace its diagnostic features.
