Characterization of a current coprogenic sample originated by Canis lupus as a tool for identifying a taphonomic agent

We study a skeletal sample digested by Iberian wolf (Canis lupus signatus) in order to finding diagnostic features of digestion caused by this agent. The remains were taken from scats collected in different natural areas in the northwestern Iberian Peninsula. We tested different methods to recover the remains with the goal of not produce biases, and we evaluated the most appropriate methods. The results were compared with those reported by other authors who have also worked with samples digested by wolves. Bias during the procurement of the skeletal assemblages seems to be a significant cause of the differences observed between the samples. We found that it was necessary to fully recover all remains and individually analyze all modifications, even in small-sized remains. Taphonomic characterization was performed by analyzing physical and biochemical modifications. We believe that these results may be useful in the study of archaeological and paleontological assemblages.     

Swidden agriculture,village longevity,and social relations in Formative central Tlaxcala: Towards an understanding of macroregional structure

Understanding social change within early village societies requires analysis at multiple scales. In this paper, we focus on macroregional structure in the Formative era of Central Mexico, based on excavations at village sites in Tlaxcala. A macroregional scale is particularly important for contextualizing developments in the study region. Rapid political evolution after 900 BC built on a legacy of organizational innovations in settled communities to the south. The earliest farmers in central Tlaxcala practiced a system of swidden agriculture developed at lower-lying elevations. Practiced on the erodible slopes of central Tlaxcala, that system led to the widespread degradation of farmland. Consequences at the village scale involved chronic instability of settlement and recurring localized stress on faunal resources.     

Dietary analysis of Piraino 1, Sicily,Italy: the role of archaeopalynology in forensic science

Pollen from intestinal contents of mummies, backed by macrofloral analysis, provides important clues to diet, medicines, and season of death. Intestinal contents were recovered from the Piraino 1 mummy from the “Sepulcher of the Priests”, Piraino Mother Church, in the province of Messina, Sicily. Using standard palynological methods and pollen concentration technique, we quantified the numbers of pollen grains per gram of coprolite. The pollen spectrum was dominated by Polygalaceae, the Milkwort Family. Polygalaceae pollen is rarely found in archaeological sites. Based on comparison to published keys, we determined that the pollen came from a species of Polygala. Polygala contains species with medicinal value. We found nine other pollen types. Traces of Potamogeton (pondweed) was observed in preliminary scans. Multiple grains of Brassicaceae (mustard family), cereal (cultivated grains), Typha (cattail) and Cheno-am were found. Single grains of Castanea (chestnut), Fabaceae (bean family), Salix (willow), and Solanaceae (tomato family) were found. The preservation of the pollen was poor except for Polygala and the cereal pollen. Brassicaceae and Cheno-am have been part of the natural pollen spectrum in Sicily since ancient times. Cereal grains were consumed with prepared food. Importantly, background arboreal pollen was nearly absent. This indicates that Piraino 1 died during months of low pollination. The absence of olive pollen is important since this plant in Sicily reaches its maximum pollination in May and June and tapers off rapidly by mid-June. Therefore, absence of the key warm season airborne pollen type suggests a post-June death. Macrofossils, especially residue from grape pulp, indicates a death in September to November. His cause of death was likely a result of multiple myeloma. The methodological differences between archaeopalynology and forensic palynology are summarized. We suggest that the palynological methods presented here should be adopted for human remains analysis in forensic palynology.     

Osteophagia and dental wear in herbivores: actualistic data and archaeological evidence

The ability of herbivores to produce damage in bones and antlers has recently been described by the present authors (Cáceres et al., 2011), showing several cases of modified bones and various stages of bone modification due to osteophagic behavior by herbivores. Herbivores chew and eat bones and antlers to make up for mineral scarcity in their diet. In this paper we describe how the consumption of bone and antlers by herbivore can result in distinct differential tooth wear, breakage and the loss of some dental pieces. This damage has also been identified in fossils. These preliminary results are especially relevant in archaeological contexts, because this marked tooth wear can be mistaken for dental disease or lead to the incorrect assignment of age to the animals.     

魁北克VS蒙特利尔——早春双城记

我牢记在心 我是在百合花下出生 却在玫瑰花下成长…… 这段小诗．在加拿大最东边的魁北克省境内,恐怕是最知名的文字了,原文是法语．第一句“Je Me Souviens”,翻译成英文就是“I do remember”,这也是每一块魁北克省车牌上出现的唯一文字。小诗里提到的百合花是法国的象征,而玫瑰是英国的象征。     

How Do Local Knowledge Spillovers and Experience Affect Export Performance?

This research paper tries to analyse the role that knowledge about foreign markets has in increasing firms' exports in clustered spaces. We consider two interrelated sources of this knowledge, a firm's direct experience and its indirect experience from other clustered firms. In particular, it is proposed that firms can improve their export performance by accessing others' knowledge as long as they have some previous direct experience that allows them to identify, understand and exploit these. Nevertheless, this positive influence of previous direct experience on exports continues only to a certain point, at which time it becomes less relevant or even negative. Firms with broad international experience have little to learn from local interactions, being more enriching establishing relationships with agents from outside the cluster. Empirical evidence gathered from wine producers located in La Rioja, Spain, confirms the moderating but decreasing importance of previous experience.     

Introduction: The gendered geographies of ‘bodies across borders’

This paper introduces the articles that comprise the themed section ‘bodies across borders’ which investigates how the social and spatial dynamics of healthcare provision are being transformed by both neo-liberalization and globalization. The articles demonstrate how the central tenets of neoliberalism: the promotion of individual autonomy as realized through the instrument of consumer choice, the privatization, outsourcing and off-shoring of core competencies and service provision, the production of highly ‘flexible’ labour are at work in re-shaping access to, and delivery of, services in the domains of reproductive health, organ donation and globalized healthcare. In paying special attention to the ways in which these practices are cut across by class, gender and ethnicity, these accounts will hopefully encourage us to reject totalizing and homogeneous narratives of medical travel in favour of those that offer more nuanced understandings of the positionality of the individuals at the heart of them.
