The Prevalence and Health Implications of Concha Bullosa in a Population from Mediaeval England

Concha bullosa is hypertrophy of the middle nasal concha attributable to its pneumatisation. It is considered to be the most common anatomical variant of the ostiomeatal complex, but it has been little studied in skeletal populations. It is uncertain whether the prevalence of concha bullosa varies in different world populations. Some have suggested that it predisposes to sinusitis, but this is controversial. The aim of the current work is to assess the prevalence of concha bullosa in a pre‐modern population and to investigate whether it is associated with maxillary sinusitis. Results showed that concha bullosa was present in 17 out of 45 individuals, a prevalence of 38%. There was no evidence of an association with sinusitis. This adds to a growing body of evidence that calls into question concha bullosa as a significant risk factor for sinus disease. Copyright © 2012 John Wiley & Sons, Ltd.     

In the Shadow of a Mild Revolution: Polish Women's Political Attitudes during the Great Sejm (1788−1792)

The Great Sejm (1788−1792) is perceived as a turning point in Stanisław August Poniatowski's reign and as one of the most important Sejms in the history of the Polish–Lithuanian Commonwealth. Studies devoted to this period concentrate in particular on parliamentary debates and deputies’ actions, as they were leading actors in this so-called Polish mild revolution. However, an interesting line of inquiry is to ask about women's experiences, as they were also aware of the importance of these events. This paper presents conclusions arising out of analysis of women's correspondence from the Archiwum Roskie (Roskie Archives): the legacy of the Lithuanian and Polish aristocratic Sapieha, Branicki and Potocki families that is maintained at the Archiwum Główne Akt Dawnych (Central Archives of Historical Records) in Warsaw. First, the article describes the group of correspondents and the source material extracted for examination. Second, it focuses on women's approaches towards the Sejm, its deputies and its attempts to reform the Republic. Lastly, it tries to explain the factors influencing women's attitudes. The study's results allow us to gain a better understanding of elite women's political culture in the late eighteenth-century Polish–Lithuanian Commonwealth.     

Did Children in Medieval and Post‐medieval Poland Suffer from Scurvy? Examination of the Skeletal Evidence

Late‐medieval and post‐medieval writings report that scurvy was a widespread condition in medieval and early historical Poland. Archaeological and historical data indicate that the diet of children was based on foods poor in vitamin C and contained small amounts of raw plant products. Also, historians emphasise that in medieval and post‐medieval Poland, there were seasonal fluctuations in food availability, frequently accompanied by poor harvests. Both resulted in long periods of poor nutrition, which affected children most severely. The aim of this study was to investigate skeletal manifestations of scurvy in subadult remains from medieval and post‐medieval Poland. Following standards described by Ortner and colleagues, anatomical sites pathognomonic of scurvy in subadults (<17 years) were assessed for abnormal porosity and hypertrophic bone among skeletons excavated from three sites: Ostrów Lednicki (dated to the 11th–14th centuries AD), Cedynia (10th–14th centuries AD) and Słaboszewo (14th–17th centuries AD). In total, 3.6% of all examined children were found to bear traces of vitamin C deficiency. The prevalence of scorbutic lesions was 4.5% for Cedynia, 2.6% for Ostrów Lednicki and 3.6% for Słaboszewo. The majority of affected children were less than 7 years of age. Scurvy was likely more widespread in the living populations than it appears from the calculation of skeletal markers, because some individuals might have recovered or died before obvious traces became apparent. Also, in some children, scurvy might not have reached an advanced stage, identifiable in the skeletal material. The prevalence of scurvy reflects not only dietary patterns but also food storage and preparation techniques adopted in the Polish territories during the Middle Ages, which contributed to low intakes of vitamin C.

Skeletal Evidence for Otitis Media in Mediaeval and Post‐Mediaeval Children from Poland,Central Europe

In palaeopathological research, otitis media (OM) is a rarely reported disease, although it is one of the most common diseases of childhood, with potentially severe consequences resulting in physical and social impairment, or even death. The episodes of OM are often preceded by upper respiratory tract infections, though the aetiology of OM is multifactorial, with significant role of environmental factors. In archaeological skeletons, middle ear inflammation is identified as erosive lesions and new bone formation of auditory ossicles. The aim of this study was to examine the skeletal signs of OM in children from a mediaeval early urban site (Cedynia) and a post‐mediaeval rural site (Słaboszewo) located on the territory of Poland. Among the entire sample (N = 435), ear bones were present in 99 skeletons. The total of 168 ossicles were examined. The general frequency of individuals with eroded ossicles was 47.5% (53.4% in Cedynia and 39.0% in Słaboszewo). In the total sample, 33.9% of ear bones showed pathological changes, with the incudes being most frequently affected. The frequency of altered ossicles was significantly higher in the early urban site than in the rural settlement (42.2% vs 25.9%, respectively; Fisher exact test, p = 0.0339). The children aged 0–3 years old tend to have a higher frequency of altered ear bones than the children aged 4–11 years old. The majority of the mastoid processes of the subadults with ear bone erosion show abnormal pneumatisation pattern. The results indicate that the environmental and socio‐cultural conditions in the stronghold likely made their inhabitants more prone to upper respiratory tract infections than the inhabitants of the village. A variety of factors may be responsible for this pattern, such as exposure to dust, environmental pollution, indoor pollution, wood smoke, occupation, population density, sanitation and quality of housing.

Not just cattle: Cranial perforations revisited

The phenomenon of perforated cattle skulls is well known to archaeozoologists. It is a condition that has not only been reported during routine faunal analyses but, unusually for animal palaeopathological studies, it has also been the subject of dedicated research papers. A revolutionary moment in the understanding of this anomaly came with its detection in the skull of a European bison. As a result of this discovery, a developmental disorder of genetic origin is now accepted as the most probable cause. In this paper, it is suggested that the perforations are caused by a developmental disorder that is expressed during the pneumatisation of the frontal, parietal and occipital bones in animals with a large sinus frontalis. The first published example of this condition in pig supports this hypothesis. It is argued that the anomaly is a hereditary trait caused by a recessive gene, the phenotypic expression of which only appears in homozygous recessive individuals. Higher incidences of this condition in past cattle and pig populations in certain places at times, may therefore testify to the occurrence of population bottlenecks and/or inbreeding practices.

Global Horizons: Mexico,the Third World,and the Non-Aligned Movement at the Time of the 1961 Belgrade Conference

This paper analyses the autonomous streak that marked Mexico's foreign policy during the presidency of Adolfo López Mateos (1958–64). Throughout this period, Mexico showed reluctance to participate fully in the flagship Kennedy programme for Latin America, the Alliance for Progress. At the same time, the López Mateos government adopted a position of defence for Cuba's right to self-determination in spite of Washington's attempts to eradicate the Cuban Revolution from the Western Hemisphere. During López Mateos's term, Mexico tried for the first time in its history to elaborate a foreign policy with broader international outreach, an effort highlighted by the Mexican presidential trips to Latin America and Asia as well as other countries that belonged to the Non-Aligned Movement. While historiography has explored Mexico's attitude towards the Alliance for Progress and, more consistently, the country's Cuban policy, much less attention has been dedicated to López Mateos's engagement with the Non-Aligned Movement. Focusing on Mexico's failed participation at the First Conference of Heads of State of Non-Aligned Countries celebrated in Belgrade in 1961, this article aims to fill this research gap. Indeed, even if Mexico did not ultimately participate in the conference, Mexican diplomacy did show great interest in the gathering. For a country that had formally sided with the United States after the beginning of the cold war, Mexico's flirtation with the Non-Aligned Movement represented a detour from the diplomatic path it had adopted at the end of the Second World War. This work argues that Mexico's engagement with the Non-Aligned Movement presents a different dimension of the country's international strategy during the 1960s, reflecting Mexico's desire to loosen the bipolar constraints that limited its economic development and increase its leverage with Washington.     

Cranial pathology of Ursus spelaeus ROSENMÜLLER & HEINROTH from Chateau Pignon,Basque Territories (Spain)

A complex lesion, on a skull of a female cave bear (Ursus spelaeus) associated with perforations of the frontal sinus is described. Paleopathological analysis suggests that the lesion is attributable to complex cranial trauma, probably complicated by an infection which appears to have occurred following a fight, most likely with another bear or, possibly, a cave lion (Panthera leo spelaea); at least one of the perforations observed on the skull may have been produced by the canine of a large carnivore. This hypothesis is supported by the frequent intraspecific aggressiveness documented in modern bears, and by evidence suggesting interspecific fights between cave bears and cave lions. The case is discussed in the light of other evidence reported in the literature. © 1998 John Wiley & Sons, Ltd.     

Gender in Post-Doi Moi Vietnam: Women,desire, and change

On the eve of doi moi's twentieth anniversary, this group of papers examines the impact of ‘economic renovation’ on the lives of Vietnam's women. Economically, the transformation is unarguable. Socially, the impacts have been as deep, but more uneven and possibly less predictable. These four papers examine different aspects of contemporary Vietnamese women's experience through the lens of desire: mothers confronting the age-old desire for sons under the government's small-family policy, young women's desire to explore sexuality in the strict moral environment of the countryside, piece-workers' desire for better conditions and better lives but unable to mobilize their proletarian class position in a socialist regime, and the desire of authors to evoke women's war-time roles to create a shared national remembrance of suffering, sacrifice, and loss. In their diverse ways, these papers offer unusual insights and rare glimpses into the lives of women in post-doi moi Vietnam.

El Género en Vietnam Post-‘Doi Moi’: Mujeres, deseo y cambio

La víspera de que cumple veinte años el doi moi, esta antología de papeles examina el impacto de ‘la reforma económica’ en las vidas de mujeres vietnamitas. Económicamente, no se puede discutir la transformación. Socialmente, los impactos han sido no solo profundo sino más desigual y posiblemente menos previsible. Los cuatro papeles examinan unos aspectos distintas de las experiencias contemporánea de mujeres vietnamitas a través de las lentes de deseo: madres se enfrentan al deseo antiguo de tener hijos bajo la política estatal de pequeña-familia; las mujeres jóvenes que desean a explorar su sexualidad dentro de un ambiente de morales estricto en el campo; el deseo de destajistas de tener mejores condiciones y vidas mejores pero incapaz de movilizar a sus posiciones de la clase proletaria bajo un régimen socialista; y el deseo de autores de suscitar los papeles de guerra que tenían mujeres para crear una conmemoración nacional compartida de sufrimiento, sacrificio, y pérdida. De sus modos diversos, estos papeles ofrecen perspicacias originales y raras vislumbres de las vidas de mujeres en post-doi moi Vietnam.

HISTORY AND KAIRÓS

The recent wave of interest in the “theological‐political” has focused scholarly attention on the constellation of ideas associated with “messianic time.” The term kairós belongs to this constellation, and Giacomo Marramao's brief but ambitious text of the same name both proposes and performs a “kairological” reconfiguration of the close relationship between philosophy and time. Marramao's argument for the productive potential of “cosmic disorientation” and contingency will merit the attention of historians interested in Benjamin's blend of messianism and historical materialism, and of anyone who is intrigued by the prospect of a messianism without apocalypticism.     

A New Application of the Bioarchaeology of Care Approach: A Case Study from the Metal Period,the Philippines

A case of disability in the Metal Period of the Philippines, likely requiring healthcare from others, is presented to explore aspects of group dynamics in this period of antiquity. B243, a middle‐aged man excavated from the Napa site in the central Philippines, suffered severe trauma to the right leg resulting in considerable restrictions to mobility and self‐maintenance of survival‐related behaviours such as food provision and hygiene. It is likely that B243 required assistance from others to survive for some period of time prior to eventual death. The bioarchaeology of care method was applied to assess the types of healthcare that B243 likely required and to consider potential social and biological impacts to both B243 and his community. Provision of healthcare practice in this case suggests that B243's community had access to health‐related resources, knowledge on the treatment of his injuries and underlying values in the group for sustaining human life in the case of injury and disability.

Differential diagnosis and discussion of a large nasal neoplasm from a late Bronze Age Athenian male

An adult male from the late Bronze Age of Athens, Greece, was found to have a large neoplasm in the nasal cavity. The characteristics of the lesion suggest that it was an osteoma of the ethmoid. Secondary infections of the paranasal sinuses are present as a result of the tumour blocking the sinus drainage. Copyright © 2009 John Wiley & Sons, Ltd.     

All at Sea. Rethinking fishers' identities in Australia

In fisheries a new ecological order is being created based upon conservation sciences. Bio-economic models of conservation sciences are being pursued globally in response to the crises generated by over-fishing. Drawing upon Haraway's concept of ‘cyborg politics’ we provide a material analysis of the gendered identities belonging to both the ‘old’ and ‘new’ orders. In this case study, empirical evidence is derived from observation and qualitative analysis of in-depth interviews conducted with trawlers, deckhands and managers of the Australian South East Trawl Fishery. We show how conservation sciences, framed within the New Right's economic policies, have prioritised performances of masculinity centred on managerialism over those of manual labour.

En pesquerías un nuevo orden ecológico se crea sobre ciencias de conservación. Modelos bíoeconómicos de las ciencias de conservación se persiguen global en reacción a la crisis generado de sobrepescar. Empleándose el concepto de Haraway del ‘político del ciborg’ proveemos un análisis material de las identidades de género que corresponden a los ordenes ‘viejos’ y ‘nuevos’. En este estudio de caso, la evidencia empírica se derivan de observaciones y análisis cualitativa de entrevistas profundas llevado a cabo con jabegueros, marineros de cubierta, y gerentes de la Pesquería Red Barredera de Sudeste Australia. Ilustramos como las ciencias de conservación, enmarcado dentro de las políticas económicas de la nueva derecha, han priorizado los representaciones del papel de masculinidad que se concentran en gerencialisma además de los masculinidades de labor manual.     

Redefining ‘sub‐culture’: a new lens for understanding hybrid cultural identities in East‐Central Europe with a case study from early 20th century L'viv‐Lwów‐Lemberg

This paper proposes a new definition of the term ‘subculture’, as a way of better understanding hybrid identities specific to East‐Central Europe, before applying this definition to a case study from the now‐Ukrainian city of L'viv from around 1900. The first section outlines the theory, arguing that the continued focus on the nation state – either from the ‘top down’, or else the ‘bottom up’ as a source of contestation, by historians and anthropologists, has limited the ability to study groups in the interstices of the national projects that typically remain defined in monolithic ethno‐linguistic terms. It examines the theoretical term ‘subcultures’ to propose a new definition that accounts for such hybridity, by having particular sensitivity to context (historical, social, geographical) and cultural practice, in addition to any prevailing national narratives at a given time. The case study in the second section focuses on linguistic hybridity in the city then known more commonly as Lemberg (German) or Lwów (Polish). It argues that Lemberg/Lwów/L'viv produced an urban dialect that blended Polish, Ukrainian, Yiddish and German elements. This dialect should be reassessed as a mixed, hybrid or transitional code, rather than as a linguistic variant of a titular nation. Archival evidence – in particular, court records – is quoted to show that at the lower end of L'viv society, people routinely mixed and transcended linguistic and, thereby, ethnic and religious boundaries. This offers direct evidence of a specific subsection, or subculture, in urban life where people interacted and intermingled intensely. As such, the paper offers new possibilities for investigating ‘hybrid’ identities, as well as proposing a counterpoint to recent research focusing on deliberate indifference or opposition to national segregation for various socio‐political, economic and cultural reasons (Judson 2006: 19–65; King 2002; Zahra 2008).     

Landscapes on the Margins: Gender and homelessness in Canada

This introductory article examines the issue of gendered homelessness and asks why so little academic feminist writing addresses this theme. The article begins with reference to a feminist novel—The Longings of Women by Marge Piercy—that does tackle this matter. The invisibility of the novel's homeless character is used as a way of introducing some distinctions between women's and men's homelessness. More generally, the article has two objectives. The first is to examine what feminist and other critical geographers have said, conceptually and empirically, about gendered homelessness, especially in Canada but also in other Western contexts. The second involves highlighting the problematic nature of too great a focus on visibility in relation to gendered homelessness, and offers an alternative reading drawn from examining the relations of bodies and urban space in conjunction with a discussion about the politics of scale and difference. All told, this collection of essays is an effort to highlight the often hidden and variable nature of gendered homelessness in Ontario, Canada and to argue that the theme is worthy of greater attention by feminist geographers.

Paisajes en los margines: género y la falta de vivienda

Éste artículo introductoria examina el tema de género y la falta de vivienda y pregunta porque hay pocos escritos feministas académicas que toca éste tema. El artículo empieza con relación a una novela feminista—The Longings of Women por Marge Piercy—que trata el tema. La invisibilidad del personaje sin hogar en el libro se utiliza como una manera de introducir algunas distinciones entre la falta de vivienda de mujeres y hombres. Más generalmente, el artículo tiene dos objetivos. El primer es examinar lo que feminista y otros geógrafos críticos han dicho conceptualmente y empíricamente sobre género y la falta de viviendo, no solo en Canadá sino en otros contextos Occidentales. El segundo involucra destacar la naturaleza problemática de un enfoque extensivo en la visibilidad en relación a género y la falta de viviendo, y ofrecer una lectura alternativa que viene de examinando las relaciones de cuerpos y espacio urbano conjuntamente con una discusión sobre las políticas de espacio y diferencia. En general, ésta compilación de ensayos es una tentativa para enfatizar que la naturaleza de género y la falta de vivienda en Ontario, Canadá son a menudo escondidos y variables, y además para argumentar que éste tema vale la pena de tender más atención por geógrafas feministas.     

Maxillary Sinus Infection in a 19th‐Century Almshouse Skeletal Sample

In 1984, the Monroe County Parks Department in the Highland Park section of Rochester, New York, accidentally unearthed part of an unmarked cemetery while landscaping. The cemetery was in use from approximately 1826 to 1863 and was associated with the Monroe County Almshouse. Anthropological examination of dental and skeletal pathology revealed a high incidence of dental infection, known to occasionally be a causal agent of maxillary sinus infection. Therefore, maxillary sinus infections in this sample were studied to ascertain their relationship with dental infections, sex, and age at death. The maxillary sinuses of 99 skeletons were examined for evidence of infection. The presence, location, type and extent of dental infections in the posterior teeth were also recorded. Half the sample exhibited bone remodelling in the maxillary sinus (54 individuals). Dental infections were observed in 82 individuals. Forty‐eight demonstrated signs of dental infection and maxillary sinusitis. Statistical analysis revealed that dental infection and maxillary sinus infection were not statistically related. Rather, a rhinogenic method of infection seems likely, which would appear related to the squalid air quality the 19th‐century poor were exposed to in the almshouse and city tenements.

A temporal bone lesion in a modern subject to explain a defect in the Kabwe skull

The skull of a dissection room subject was noted to have a hole in the left squamous temporal bone similar to a lesion in the Kabwe (Broken Hill) skull. Kabwe man has an 8 × 8 mm hole situated 2 cm above and slightly anterior to the left external auditory meatus (EAM). This report describes a possible mechanism for the causation of that lesion, which is illustrated by features on a modern skull. The subject is a 55-year-old man who died from carcinoma of the stomach in 1942. The skull was macerated, defatted and stored after the cadaver had been dissected by medical students. In the squamous temporal bone there was an oval shaped 9 × 8 mm hole. The base of the oval was situated 11 mm above the superior margin of the EAM with the central axis of the hole being in line with the anterior margin of the EAM. This hole forms the base of a larger intracranial pit measuring 21 mm in diameter. The hole has an irregular margin except superiorly where it is smooth and rounded, indicative of healing. Intracranially, the petrous temporal bone displayed a marked exophytic, bony outgrowth suggestive of a chronic infective condition. The tegmen tympani contained a hole 3 mm in diameter in the middle of the exophytic area. No sign of disease in the mastoid process was noted. These findings are compatible with advanced chronic ear disease which has tracked into the extradural space through the tegmen tympani, become loculated, and then eroded the squamous temporal bone. The Kabwe skull shows signs compatible with chronic ear disease. It is suggested that a mechanism similar to the one described in the modern skull could explain the lesion in the left squamous temporal bone of Kabwe man.     

‘I'd Feel Ashamed’: Girls' Bodies and Sports Participation

This article is concerned with the links between space, gender and adolescents' bodies. Drawing on data from both qualitative and quantitative research carried out with adolescents aged 13–16 in Liverpool, UK in 2001 the article examines girls' low participation rates in physical education (PE). Framed within theoretical work relating to the performance of corporeal femininities and ‘inhibited intentionality’ in reference to sporting confidence, girls' experiences of single-sex PE are compared with their perceptions of mixed PE in order to explore how the presence of boys may impact on girls' perceptions of their bodies and willingness to participate in sport. The results suggest that while girls still feel pressure from a male gaze to present their bodies to boys as passively beautiful, they also feel pressure to be competent at sport and thus present their bodies as active. However, single-sex PE does not provide a space where the male gaze is absent, suggesting this gaze has been internalized. This article explores the nature of school space in explaining differential participation rates, highlighting how sports within the space of the school, with an emphasis on competition and under the evaluative gaze of teachers, intensify some girls' fears of inadequacy in sports. The findings illustrate the complexities and contradictions present within and between girls' experiences of their bodies and sports and the relationship between school space and adolescents' bodies.

‘Siento Verguüenza’: Cuerpos de jovenas Y participación endeportes

Este artículo se ocupa de los enlaces entre espacio, género, y los cuerpos de adolescentes. Utilizando datos de una investigación cualitativo y cuantitativo que se llevó a caber con adolescentes de 13 hasta 16 años en Liverpool en 2001, examino el nivel bajo de la participación de jovenas en educación física. Las experiencias de jovenas de la educación física sólo para niñas se comparan con sus percepciones de la educación física mixta para explorar como la presencia de jóvenes (niños) influye la percepción de jovenas de sus cuerpos y sus buenas disposiciones para participar en deportes. Los resultados sugieren que mientras las jovenas sienten presión de las miradas masculinas para presentar sus cuerpos a ellos como pasivamente hermosos, sienten también la presión para estar capaz en los deportes y así presentar sus cuerpos como activos. Sin embargo, la educación física sólo para niñas no provee un espacio donde no hay una mirada masculina por que ésta mirada se ha sido interiorizado. Deportes en el espacio de la escuela tienen un énfasis en la competición y una mirada evaluativa de maestros y como consecuencia se intensifica el miedo de jovenas de ser inadecuado en deportes. Las conclusiones ilustran las complejidades y contradicciones en y entre las experiencias de jovenas de sus cuerpos y deportes, y la relación entre el espacio de la escuela y los cuerpos de adolescentes.     

MakingGüeras: Selling white identities on late-night Mexican television

This article examines discourses of whiteness and color in Mexico through a discussion of White Secret, a widely available skin-lightening cosmetic product. In an analysis of a televised infomercial advertising the product, we examine contextualizations of whiteness in Mexico, as figured through the product's representations of light-skinned female bodies and advanced cosmetic technology. We consider the ways that White Secret can speak to broader conceptualizations of whiteness and identity and, furthermore, argue that such an engagement points to the need to interrogate the geographical and epistemological limits of current understandings of whiteness based in Anglo-American and Latin-American contexts.

Creando güeras: La venta de identidades blancas en la televisión Mexicana de media noche En este artículo, hacemos un análisis sobre los discursos de ‘blancura’ y de color con respecto a la población en México a través de una discusión sobre ‘White Secret’, un producto cosmético para aclarar la piel que es muy disponible en México. Por un análisis de un ‘info-nuncio’ que sale por la televisión anunciando el producto ‘White Secret’, exploramos los entretejemientos de la construcción de blancura en México y como este ‘info-nuncio’ manipula imágenes de los cuerpos de güeras (mujeres de piel clara) y tecnología cosmética avanzada. Reflexionamos acerca de las maneras que el producto ‘White Secret’ pueda hablar a concepciones más amplias sobre la construcción de identidad y blancura y además, discutimos que tal exploración indica la necesidad de interrogar los limites epistemológicos y geográficos de la comprensión actual de la construcción de blancura basados en los contextos Latino Americanos y Anglo Americanos.
