Authors: Sengupta Subhalakshmi , Chatterjee Uttara , Bandyopadhyay Ranjana , Bhowmick Kuntal , Banerjee Sugata 
Published: April 2012

AbstractPrimary pulmonary neoplasms are uncommon in children and represent a wide spectrum of pathology from benign to malignant. They are quite different in their histopathologic distribution from that of adults. This study was done to analyze the histopathologic spectrum of primary lung tumors in children. All the resected specimens of lung in children over a period of 5 years were studied and only the cases of primary pulmonary neoplasms were further analyzed. There were two cases of inflammatory myofibroblastic tumor. The patients were boys aged 10 and 12 years, respectively. One case of bronchial carcinoid was diagnosed in a boy of 12 years. There were one case each of pleuropulmonary blastoma (PPB) in a girl of 9 years and pulmonary blastoma (PB) in a girl of 2 years of age. In our study, the two cases of inflammatory myofibroblastic tumor had excellent prognosis. However, the cases of PPB and PB were both associated with poor clinical outcome, whereas the case of bronchial carcinoid has been doing well on follow-up.

Published: April 2012

AbstractWe present a patient with metastatic leiomyosarcoma of the prostate who achieved complete response with chemotherapy. A 70 years old male patient presented with urinary tract symptoms and a prostatic mass. After having been treated as carcinoma prostate, he presented with progressive pelvic mass, lung and bone metastases to our hospital. Repeat biopsy was suggestive of prostatic leiomyosarcoma. He was treated with chemotherapy with the ifosfamide-epirubicin regimen and achieved complete remission on positron emission tomography/computerized tomography after three cycles. He was given a total of six cycles of chemotherapy and continues to be disease-free after 8 months. Although adenocarcinomas are the commonest prostatic malignancies in the elderly, a careful evaluation is essential to rule out alternative diagnoses. Our case report illustrates the potential role of combination chemotherapy in the management of advanced leiomyosarcoma of the prostate. The literature on this entity is reviewed.

Published: April 2012

AbstractMalignant ectomesenchymomas are rare tumors. This tumor affects predominantly young children. Most common site is head and neck. A multi modality approach should be appropriate for this soft-tissue tumor. We present a 43 year old female with malignant ectomesenchymoma of the nasal cavity.
Left-orderability and Exceptional Dehn Surgery on Twist Knots
Authors: Teragaito Masakazu 
Published: April 2012

Abstract.We show that any exceptional non-trivial Dehn surgery on a twist knot, except the trefoil, yields a 3-manifold whose fundamental group is left-orderable. This is a generalization of a result of Clay, Lidman, and Watson, and also gives a new supporting evidence for a conjecture of Boyer, Gordon, andWatson.
On Prey Mobility, Prey Rank, and Foraging Goals
Authors: Ugan Andrew , Simms Steven 
Published: April 2012

AbstractIn their recent paper “In Pursuit of Mobile Prey,” Bird, Bliege-Bird, and Codding (2009) identify a negative relationship between body size and post-encounter returns among Martu prey in western Australia, attributing the phenomena to the greater mobility of large animals and associated risk of hunting failure. While this phenomenon has implications for archaeological applications of foraging models that assume body size and on-encounter returns are positively correlated, the Martu data may be less exceptional than they appear. Here we outline the reasons for our skepticism, point out areas in which we are in agreement, and build upon their findings by exploring the trade-offs between foraging to maximize efficiency and immediate returns and foraging for purposes other than immediate provisioning.
High Resolution Radiocarbon Dating at the Gerstle River Site, Central Alaska
Authors: Potter Ben A. , Reuther Joshua D. , Newbold Bradley A. , Yoder David T. 
Published: April 2012

AbstractEarly Holocene cultural material at Gerstle River, central Alaska, provides excellent contextual controls for examining variability in radiocarbon dating. Over 4,000 bone and teeth fragments are directly associated with over 7,000 lithic artifacts and 10 discrete charcoal-rich hearths in a thin occupation layer (∼10 cm vertical thickness) within well-stratified loess deposits. Radiocarbon dating of the hearth features indicates overlapping ages at 2σ, suggesting contemporaneity. This study uses the high level of resolution at Gerstle River to evaluate systematic radiocarbon variation due to different materials (collagen and charcoal), different pretreatments of collagen (regular and ultrafiltered), and interlaboratory variation through paired bone and hearth charcoal dates, split samples, and cross-checks. Accurately dating bone collagen is important given the closer association of dated samples with human activities (e.g., butchering) compared with charcoal fragments in certain contexts (e.g., driftwood, paleosols, or alluvial deposits). This study demonstrates the efficacy of bone collagen dating with ultrafiltration to counter potential site-specific contamination. These results also indicate that even in high-resolution situations with little evidence for old-wood effect and contamination, considerable variability can exist among cross-check and even split samples from single pieces of charcoal from short-lived species.
Craft Specialists at Moche: Organization, Affiliations, and Identities
Authors: Bernier Hélène 
Published: April 2012

AbstractThis article examines the organization of specialized craft production at the urban site of Moche, known as the capital of the Southern Moche state. Recent excavations in workshop contexts revealed that the urban population of Moche was in part composed of ceramists, metallurgists, and lapidaries. These craft specialists played a significant role in the economic, political, and religious spheres of the Moche polity. Data obtained during excavations of workshops and domestic compounds are used to analyze the context, scale, and intensity of craft production, taking into account the nature of the goods produced and the identity of consumers. The discussion also considers the integration of craft specialists into the daily life and social structure at the site of Moche. Excavations showed that while urban craft specialists were not independent, they were not tightly controlled by a centralized ruling elite. They produced symbolic goods in various small to middle-scale workshops integrated into residential units, under the direct authority of urban leaders taking advantage of this particular organization of semi-attached craft production in various status-building strategies.
Continuity and Transformation During the Terminal Middle Horizon (A.D. 950–1150): A Bioarchaeological Assessment of Tumilaca Origins within the Middle Moquegua Valley, Peru
Authors: Sutter Richard C. , Sharratt Nicola 
Published: April 2012

AbstractPrevious archaeological studies suggest that terminal Middle Horizon Tumilaca populations (cal A.D. 950–1150) of the middle Moquegua Valley represent direct descendants of earlier Chen Chen-style Tiwankau colonists of the region. This study tests this idea by comparing dentally derived biodistance analyses of Tumilaca, Chen Chen-style, Tiwanaku, and other regional samples. The results indicate that the Tumilaca and Chen Chen-style mortuary samples are similar to one another suggesting that these populations might share an ancestral-descendant relationship. The phenetic relations of the Tumilaca and Chen Chen to other regional samples are also discussed.
Cerro Lampay: Architectural Design and Human Interaction in the North Central Coast of Peru
Authors: Vega-Centeno Rafael 
Published: April 2012

AbstractRecent fieldwork concerning the late Preceramic/late Archaic period on the PeruvianNorth-Central Ccoast has revealed the existence of large architectural complexes, which scholars interpret as indicative of social complexity. This article is especially concerned with architectural design as an effective means to define social and political organization at Cerro Lampay. It concludes that there was not a highly formalized hierarchy but that power positions within the community could have been negotiated through ritual practices that included the dual organization of participants. It is highly probable that the residents of the North Central Coast were in constant and intense interaction during the late Archaic, which may have resulted in displays of competitive emulationin ritual settings.
Lecturas estratigráficas: arquitectura funeraria y depositación de residuos en el sambaquí Jabuticabeira II
Authors: Villagran Ximena Suarez , Klokler Daniela , Nishida Paula , Gaspar Maria Dulce , DeBlasis Paulo 
Published: April 2012

ResumenSambaquís (concheros o shell mounds) son construcciones antrópicas que aperecen en la costa brasileña hace aproximada mente 8000 años erguidas a partir de la acumulación formal de valvas de moluscos. En el Estado de Santa Catarina, algunos sitios tienen la particularidad de presentar un depósito ictiológico superior con características estratigráficas y composicionales semejantes al depósito malacológico (conchero) subyacente. La aparición del depósito superior fue tradicionalmente asociada a cambios en la subsistencia de estos grupos, con el reemplazo del consumo de moluscos por peces. Sin embargo, análisis faunísticos indicaron que la pesca siempre fue una actividad de subsistencia predominante. Nuevas interpretaciones del fenómeno sugirieron que la substitución de valvas de molusco por huesos de pescado responde a alteraciones tardías en la funcionalidad de los sitios. En este trabajo, la micromorfología de depósitos arqueológicos fue aplicada como herramienta principal de análisis para descifrar la formación del sitio Jabuticabeira II. A partir de la combinación de estudios geoarqueológicos, microestratigráficos y arqueofaunísticos realizados en ambos depósitos, proponemos un modelo para la formación de este sambaquí como resultado de sucesivos procesos de depositación antrópicos asociados a actividades rituales. Estos procesos envolvieron la quema de materiales, acumulación y re-depositación como diferentes etapas en el ritual funerario del grupo constructor. El origen de los materiales constructivos es discutido desde un abordaje contextual a través de la valorización del papel simbólico que la depositación de residuos tuvo entre estas poblaciones.
Inka Sacrifice and the Mummy of Salinas Grandes
Authors: Besom Thomas 
Published: April 2012

AbstractIn the last 25 years, materials from some human sacrifices that the Inkas carried out on high mountains (e.g., Aconcagua and Llullaillaco) have been thoroughly analyzed and adequately interpreted. Remains from immolations that took place in other contexts, however, which tend to be poorly preserved and incompletely studied, are not as well understood. In this article, I begin to remedy this imbalance in our knowledge by discussing the sacrifice from Salinas Grandes, which is a salt flat situated in northwestern Argentina. I describe the body of the victim—who was very likely aqhapaq hucha, a specially chosen child—and his clothing, accouterments, and hairstyle. I offer hypotheses on where he came from and on the reasons behind his ritual dispatch. I demonstrate how the different items that were buried with him all contributed to the meaning of his immolation. I also show how the lords of Cuzco may have employed the sacrifice to tie the region where the salt flat is located to the empire.
The La Tolita—Tumaco Culture: Master Metalsmiths in Gold and Platinum
Authors: Scott David A. 
Published: April 2012

AbstractThe archaeological setting of the La Tolita—Tumaco culture is briefly discussed as a framework for the examination of the metallurgy of the area, in particular the gold—platinum alloys used to make platinum-coated gold objects, platinum—gold sintered alloys, and platinum—gold foil—plated objects. The sophisticated approach to the manipulation of metallic materials resulted in several notable advances being made by the La Tolita—Tumaco culture: the production of extremely fine rectangular wire, bimetallic tumbaga alloys, small lead spheres inlaid with platinum, soldering, granulation, and a degree of sophistication to metalworking that is very impressive and, in some cases, unique in the world. Some selected examples are discussed, and the microstructure of a representative selection of the La Tolita material, bimetallic tumbaga construction, the initial sintered gold—platinum product, platinum-plated gold, and heavily worked gold—platinum composite artifacts are presented.
People Who Lived in Stone Houses: Local Knowledge and Social Difference in the Classic Maya Puuc Region of Yucatan, Mexico
Authors: Carmean Kelli , McAnany Patricia A. , Sabloff Jeremy A. 
Published: April 2012

AbstractThis study builds on the premise that local knowledge of limestone—and its workable characteristics—was foundational to landscape inhabitation in the Puuc region of Yucatán, México. Classic Maya architecture of the northern Yucatán generally is considered to represent the apogee of Maya construction prowess with extensive use of core-veneer masonry and the creation of tall, wide corbelled vaults. Less commonly discussed is the variable distribution of high-quality limestone across the Yucatán, the social matrix that undergirds the quarrying, transporting, and working of limestone, and the pronounced social differences materialized in stone architecture. This study explores these three topics by bringing to bear Yucatec Mayan linguistic evidence and excavation data from the archaeological site of Sayil, in the hilly Puuc region of Yucatán. That information provides a basis for understanding the development of a sprawling residential complex, the role that variable limestone quality played in its expansion, and serves as an index of intra-compound social difference. Late additions to the dwellings indicate that recognition of the cultural value of carved stone persisted long after masonry skills became attenuated. The durability of stone renders it a particularly effective—if underutilized—medium for interpreting social landscapes of the past.
Ritual among the Masses: Deconstructing Identity and Class in an Ancient Maya Neighborhood
Authors: Blackmore Chelsea 
Published: April 2012

AbstractEquating a single cultural group to a classificatory scheme has implications for not only how archaeologists develop the concept of cultural identity but how we investigate and theorize about internal social dynamics within that same society. For the ancient Maya, social organization remains largely understood as a two-class system—that of commoner and elite. While these categories reflect the extreme ends of known social strata, they inadequately characterize the reality of day-to-day interactions. This has led to tacit assumptions that commoners did not participate in or comprehend the political and social complexity of the world around them. This paper examines how occupants of a Late Classic Maya neighborhood employed ritual and public practices as a means of social differentiation. Excavations at the Northeast Group, part of the ancient Maya site of Chan, Belize, identified considerable diversity between households, suggesting that occupants shaped status and identity through the control and centralization of ritual. Understanding how people distinguished themselves within the context of a neighborhood provides direct evidence of class complexity, challenging traditional models of commoner behavior and more importantly the role they played in ancient Maya society as a whole.
Formation of a Complex Polity on the Eastern Periphery of the Maya Lowlands

Published: April 2012

AbstractThis paper pursues the application of a central tenet of the dual-processual framework, the corporate/network continuum, to the development of Uxbenká, a small monument-bearing polity in the southern Maya Lowlands. During its growth, Uxbenká underwent a transformation from a small farming community to a complex polity with many of the trappings of elite authority that characterizes Classic Maya centers. It was one of the earliest complex polities to develop on the southeastern periphery of the Maya lowlands during the Early Classic period (A.D. 300—600). The polity was founded upon earlier agricultural communities that are now known to extend back to at least A.D. 100. Starting after A.D. 200 the location of the original agricultural village (Group A) was leveled and reorganized to form a public monument garden and the center of political authority throughout much of the Classic period (A.D. 400—800). In this article we present radiocarbon ages from well-defined stratigraphic contexts to establish a site chronology. Based on these data we suggest that by A.D. 450 Uxbenká was the center of a regional political system connected to some of the larger polities in the Maya world (e.g., Tikal). We argue that at this time Uxbenká underwent a significant change from a polity organized by a corporate inclusionary form of ruler-ship to a more networked one marked by exclusionary authority vested in elites who privileged their ancestral relations and network interactions across the geopolitical landscape.
Urns, Bowls, and Ollas: Pottery-Making Practices and Technical Identity in the Southern Andes During the Late Period (ca. A.D. 900—A.D. 1450) (Catamarca, Northwestern Argentine Region, Argentina)
Authors: De La Fuente Guillermo A. 
Published: April 2012

AbstractThis paper presents studies and discussions of pottery-making practices during the Late period (ca. A.D. 900—1450) in Northwestern Argentina. It stems from an extensive archaeological research project carried out in the middle sector of the Abaucán Valley, Province of Catamarca, Argentina. Pottery production during this period is evaluated through the study of technological choices and technical identity, as well as its relationship to the technical behaviors developed by potters. The analysis of a large sample of ceramic sherds, complete vessels, and overfired sherds indicates that the potters produced a very narrow repertoire of ceramic forms (bowls, urns, and ollas) using local raw materials and technology, the latter with a strong hold in the area. Pottery production during the Late period was carried out in household contexts, becoming increasingly intensified and concentrated with the appearance of Inkas in the region. Additionally, some ideas are discussed concerning the technological choices of ancient potters during this period, and the implications for technological studies in archaeological ceramics.
The Square-Room Unit as an Emblem of Power and Authority within the Initial Period Sechín Alto Polity, Casma Valley, Peru
Authors: Pozorski Shelia , Pozorski Thomas 
Published: April 2012

AbstractSome 3,500 years ago, the Sechín Alto Polity built large, precisely planned cities, one of which contained the largest structures in the New World at that time. Such accomplishments reflect strong, enduring leadership, and we propose that the power and leadership role of these leaders was tangibly manifested by a unique, widely used architectural element and by a related symbol within polity iconography. The distinctive architectural form is a free-standing module that is omnipresent in power loci: temple, palace, storehouse, mid-level administrative buildings, roadside structures, and a satellite site. We also interpret recurring symbols within Sechín Alto Polity iconography as more abstract representations of this architectural form in its capacity as a power symbol. The essence of this "architecture of power" transcended time as the modular form was imitated by a subsequent polity.
Death and Religion in the Southern Moche Periphery: Funerary Practices at Huambacho, Nepeña Valley, Peru
Authors: Chicoine David 
Published: April 2012

AbstractThis article explores religion, death, and mortuary practices in the Southern Moche (A.D. 1-800) periphery as viewed through the excavation of grave contexts at the site of Huambacho, Nepeña Valley, Peru. Moche influence reached Nepeña as is visible in the construction of religious buildings at the site of Pañamarca and the presence of Moche style ceramics at several sites. In 2003 and 2004, scientific excavations at Huambacho, an Early Horizon center mainly built and occupied during the first millennium B.C., yielded a series of intrusive graves containing Gallinazo, Virú, and Moche style objects. This contribution contextualizes these discoveries and focuses on the analysis of funerary patterns of burial, osteological evidence, and symbolic meanings with the objective of understanding local funerary practices and Moche religious and cultural expressions. Symbolic references to coast-highland interactions, inversions in body positioning, and possible human sacrifices bring insights into the complex and potentially tense sociohistorical cirmcumstances in Nepeña during the Moche phase.
Consumo Antropico de Pequeños Mamiferos en el Holoceno de Argentina Central: Perspectivas desde el Abrigo Rocoso Quebrada del Real 1 (Pampa de Achala, Cordoba)
Authors: Medina Matías , Rivero Diego , Teta Pablo 
Published: April 2012

ResumenSe estudiaron los restos de micromamíferos y otros pequeños vertebrados (Número de Especímenes Identificados = 2,754) del sitio arqueológico Quebrada del Real 1, provincia de Córdoba, Argentina. Las muestras analizadas estuvieron dominadas por roedores caviomorfos de las familias Caviidae y Ctenomyidae, incluyendo taxones de tamaño relativamente grande (200—700 g), hábitos coloniales o gregarios, ubicación predecible, y fáciles de explotar como recurso. El estudio tafonómico de los restos sugiere que las acumulaciones tienen un origen mayoritario en actividades antrópicas de consumo. Las evidencias incluyen la presencia de huellas de corte (especialmente en mandíbulas y huesos del esqueleto apendicular) y un patrón diferencial de alteración térmica, mayormente restringido a las porciones distales de tibias. En el contexto regional, el consumo de pequeños vertebrados sugiere que la implementación de una dieta de amplio espectro posiblemente no sea un proceso arqueológico exclusivamente tardío, sino que se remonta al menos al límite Holoceno Medio-Tardío (ca. 3000 a.P.).
