Personas, no piedras: preservar el pasado manteniendo un futuro

Best practices in cultural heritage management must include economic, social and cultural benefits to the people and communities where they are located; that is, in the words of the conference organizers, they must serve as local “wealth increasers”. Yet far too often even when site management plans include “wealth increase” as a goal, few such benefits are actually realized, most frequently the result of either poorly conceived or implemented plans, or both. The processes by which heritage serves as a “wealth increaser” have been badly under theorized, and site managers receive little or no training in the subject. In this paper, I set forth some theoretical considerations and practical steps to generate economic, social and cultural benefits in communities where cultural heritage sites are located. Rather than top-down mass tourism models in which most of any economic benefits accrue outside of the local community and there is little or no incentive to preserve a site, I propose a model predicated upon social entrepreneurship, economic sustainability and enhanced local control, and provide case studies that demonstrate significant economic, social and cultural benefits. I utilize projects of the work of the Sustainable Preservation Initiative in order to demonstrate the efficacy of this model.Las mejores prácticas en gestión del patrimonio cultural deben incluir beneficios económicos, sociales y culturales para las personas y las comunidades donde están ubicadas; es decir, en palabras de los organizadores del Congreso, debe servir como “incrementadores de riqueza”. Todavía demasiado frecuentemente incluso cuando la gestión de un sitio incluye “aumento de la riqueza” como un objetivo, en muy raras ocasiones esos beneficios realmente se llevan a cabo; con mayor frecuencia el resultado son planes mal concebidos o mal implementados, o ambos. Los procesos por los cuales el patrimonio sirve como un “aumentador de riqueza”han sido mal implementados, y los administradores del sitio reciben poca o ninguna preparación para ello. En este artículo, se establecen algunas consideraciones teóricas y pasos prácticos para generar beneficios económicos, sociales y culturales en las comunidades donde se encuentran sitios de patrimonio cultural. En lugar de un modelo de turismo masivo, siguiendo un esquema piramidal de arriba a abajo, donde los beneficios económicos se acumulan fuera de la comunidad local y hay pocos o ningún incentivo para preservar un sitio, propongo un modelo basado en el emprendimiento social, la sostenibilidad económica y un control local mejorado, proporcionando estudios de caso que muestran importantes beneficios económicos, sociales y culturales. Utilizo proyectos de trabajo de preservación sostenible para demostrar la eficacia de este modelo.Depto. de Prehistoria, Historia Antigua y ArqueologíaFac. de Geografía e HistoriaTRUEMinisterio de Economía y Competitividad (MINECO)pu

Theaters of Power: Inka Imperial Performance

Military and police power has proven time and again to be necessary but not sufficient to create and maintain an empire. Empires must employ a multitude of strategies to expand and survive, one of the most important of which is state-sanctioned public spectacles, ceremonies, and rituals. This dissertation examines the roles of these large-scale non-quotidian performances that are organized and directed by political agents, occur generally at specified times and locations, and include elements of the spectacular, theatricality, cosmological invocation, and feasting. These, state-sanctioned public spectacles, ceremonies, and rituals, have received inadequate attention from archaeologists. Archaeologists traditionally focused on the development of administrative and economic systems, ignoring the roles of performances in imperial expansion, which have often been considered epiphenomenal. My own research has focused on one of these empires, the Inka, and how it grew from a small single valley in Peru to a powerful polity ranging north to Ecuador and Colombia, south to Chile and Argentina, and east to Bolivia and Paraguay. This expansion occurred without many of the tools historically considered critical to such expansion, including a writing system, horses, and the wheel. I analyze religious and state constructions and spaces for their roles in and as the settings for spectacles and ceremonies. Utilizing a performance-based perspective and theories of semiotics and pragmatics drawn from semiotic anthropology, I focus on a particular set of Inka performance spaces and their role in imperial expansion and control: the capital Cuzco and certain replicas of that capital constructed in other parts of the empire. I suggest that these sites served as the settings for a calendar of ritual ceremonies and spectacles that referenced certain repeated physical attributes and were performed by and for an audience of the Inka themselves, and did not, like other performances in the empire, involve the meaningful participation of other social groups within the empire. I also suggest that these Cuzco replicas were strategically placed in areas of war and rebellion where the utilization of ritual performance to maintain, reinforce, inculcate and manipulate Inka ideology, identity, and power was a critical element of imperial strategy

Treatment of Gastrointestinal Bleeding in the Biliopancreatic Limb with Embolization in a Patient with Duodenal Switch Anatomy

Introduction: Biliopancreatic diversion with duodenal switch (BPD/DS) is an uncommon type of bariatric surgery that can rarely lead to bleeding in the biliopancreatic limb. The altered anatomy poses significant diagnostic and therapeutic challenges. Case Presentation: We present an unusual case of a woman status post-BPD/DS nearly a decade ago who presented with gastrointestinal bleeding in the duodenum of the biliopancreatic limb, a rare phenomenon given the unique surgery. Conclusion: We illustrate a promising minimally invasive option of successfully treating the bleeding by interventional radiology (IR) embolization as an alternative to more invasive and challenging options of balloon-assisted enteroscopy, lumen-apposing metal stent placement and surgical intraoperative enteroscopy

Mathematical images in advertising: constructing difference and shaping identity, in global consumer culture

Mathematics educators have long emphasised the importance of attitudes and feelings towards mathematics, as crucial in motivating (or not) its learning and use, and as influenced in turn by its social images. This paper is about images of mathematics. Our search for advertisements containing such images of in UK daily newspapers, during 2006-2008, found that 4.7% of editions included a ‘mathematical’ advert, compared with 1.7% in pilot work for 1994-2003. The incidence varied across type of newspaper, being correlated with class and gender profiles of the readership. Three-quarters of advertisements were classified as containing only very simple mathematics. ‘Semiotic-discursive’ analysis of selected advertisements suggests that they draw on mathematics not to inform, but to connote qualities like precision, certainty and authority. We discuss the discourse on mathematics in advertising as ‘quasi-pedagogic’ discourse, and argue that its oversimplified forms, being empty of mathematical content, become powerful means for regulating and ‘pedagogising’ today’s global consumers

On the verge of Umdeutung in Minnesota: Van Vleck and the correspondence principle (Part One)

In October 1924, the Physical Review, a relatively minor journal at the time, published a remarkable two-part paper by John H. Van Vleck, working in virtual isolation at the University of Minnesota. Van Vleck combined advanced techniques of classical mechanics with Bohr's correspondence principle and Einstein's quantum theory of radiation to find quantum analogues of classical expressions for the emission, absorption, and dispersion of radiation. For modern readers Van Vleck's paper is much easier to follow than the famous paper by Kramers and Heisenberg on dispersion theory, which covers similar terrain and is widely credited to have led directly to Heisenberg's "Umdeutung" paper. This makes Van Vleck's paper extremely valuable for the reconstruction of the genesis of matrix mechanics. It also makes it tempting to ask why Van Vleck did not take the next step and develop matrix mechanics himself.Comment: 82 page

Rural High North: A High Rate of Fatal Injury and Prehospital Death

Finnmark County is the northernmost county in Norway. For several decades, the rate of mortality after injury in this sparsely inhabited region has remained above the national average. Following documentation of this discrepancy for the period 1991–1995, improvements to the trauma system were implemented. The present study aims to assess whether trauma-related mortality rates have subsequently improved. All injury-associated fatalities in Finnmark from 1995–2004 were identified retrospectively from the National Registry of Death and reviewed. Low-energy trauma in elderly individuals and poisonings were excluded. A total of 453 cases of trauma-related death occurred during the study period, and 327 of those met the inclusion criteria. Information was retrievable for 266 cases. The majority of deaths (86%) occurred in the prehospital phase. The main causes of death were suicide (33%) and road traffic accidents (21%). Drowning and snowmobile injuries accounted for an unexpectedly high proportion (12 and 8%, respectively). The time of death did not show trimodal distribution. Compared to the previous study period, there was a significant overall decline in injury-related mortality, yet there was no change in place of death, mechanism of injury, or time from injury until death. Changes in injury-related mortality cannot be linked to improvements in the trauma system. There was no change in the epidemiological patterns of injury. The high rate of on-scene mortality indicates that any major improvement in the number of injury-related deaths lies in targeted prevention

Endophenotypes in a Dynamically Connected Brain

We examined the longitudinal genetic architecture of three parameters of functional brain connectivity. One parameter described overall connectivity (synchronization likelihood, SL). The two others were derived from graph theory and described local (clustering coefficient, CC) and global (average path length, L) aspects of connectivity. We measured resting state EEG in 1,438 subjects from four age groups of about 16, 18, 25 and 50 years. Developmental curves for SL and L indicate that connectivity is more random at adolescence and old age, and more structured in middle-aged adulthood. Individual variation in SL and L were moderately to highly heritable at each age (SL: 40–82%; L: 29–63%). Genetic factors underlying these phenotypes overlapped. CC was also heritable (25–49%) but showed no systematic overlap with SL and L. SL, CC, and L in the alpha band showed high phenotypic and genetic stability from 16 to 25 years. Heritability for parameters in the beta band was lower, and less stable across ages, but genetic stability was high. We conclude that the connectivity parameters SL, CC, and L in the alpha band show the hallmarks of a good endophenotype for behavior and developmental disorders

Crash characteristics and patterns of injury among hospitalized motorised two-wheeled vehicle users in urban India

<p>Abstract</p> <p>Background</p> <p>Traffic crashes and consequent injuries represent a growing public health concern in India, particularly in light of increasing motorization. Motorised two-wheeled vehicles (MTV) constitute a large portion of the vehicle fleet in India. We report the crash characteristics and injury patterns among a cohort of MTV riders and pillions presenting to hospital post-crash.</p> <p>Methods</p> <p>Consecutive MTV riders and pillions, whether alive or dead, injured in a road traffic crash presenting to the emergency departments of two government hospitals and three branches of a private hospital in urban Hyderabad, India, were recruited to this study.</p> <p>Results</p> <p>378 MTV users were enrolled to the study of whom 333 (88.1%) were male, 252 (66.7%) were riders and median age was 31.3 years. A total of 223 (59%) MTV users were injured in multi-vehicle crashes while one-third had a frontal impact. The majority (77%) were assessed as having a Glasgow coma score (GCS) of 13–15, 12% a GCS of 9–12 and 11% a GCS of 3–8. No difference was seen in the severity distribution of injuries based on GCS among riders and pillions. Open wounds and superficial injuries to the head (69.3%) and upper extremity (27%) and lower extremity (24%) were the most common injuries. 43 (11%) sustained an intracranial injury, including 12 (28%) with associated fracture of the bones of the head. There were few differences in types of injuries sustained by riders and pillions though riders had a significantly lower risk of crush injuries of the lower extremity than pillions (relative risk, RR 0.25, 95% CI 0.08–0.81) and female pillions were at a significantly lower risk of sustaining fractures of the lower extremity than male pillions (RR 0.30, 95% CI 0.09 – 0.94). Overall, 42 (11%) MTV users died, of which 42.8% died before reaching the hospital. Only 74 (19.6%) MTV users had worn a helmet correctly and failure to wear a helmet was associated with a five times greater risk of intracranial injury (RR 4.99, 95% CI 1.23–20.1). Of the 19 pre-hospital deaths, 16 (84%) had not worn a helmet.</p> <p>Conclusion</p> <p>Head injuries accounted for the major proportion of injuries sustained in MTV users. Non-helmet use was associated with increased risk of serious head injuries. The data presented on the nature and severity of injuries sustained by MTV users can assist with planning to deal with these consequences as well as prevention of these injuries given the high use of MTV in India.</p

A case of learning mathematics the hard way as a teaching assistant

This paper develops early data from a qualitative longitudinal study of the first cohort of five students making the transition from teaching assistant in secondary school to specialist teacher of secondary mathematics. Data from a second cohort of four women and one man starting in 2003 is less complete, but used as appropriate. Bernstein's work on subject classification frames an argument that this student group navigates simultaneously two mathematics discourses: hard university mathematics, and everyday mathematics as experienced by the lower ability school pupils that the students support. This raises questions about the purpose and scope of the students work in school with respect to their mathematics learning, and vice versa. The study of conventional mathematics undergraduates for the ESRC (Macrae, Brown, and Rodd, 2003) provides a foil against which to compare approaches to learning mathematics, raising the possibility of a rethink of pre-requisite pre-qualification, and potential relations between university mathematics and work-place learning in secondary schools
