A case of concha bullosa mucopyocele in a medieval human skull

The term ‘concha bullosa’ refers to the pneumatisation of the intranasal turbinates. The pneumatisation can occur at any level (superior, middle, inferior), but the term is typically used to describe the aeration of the middle turbinate. This case report concerns a medieval skull from Tomb Chamber Number One in St. Nicholas's Church in Głogów, Poland. The burial dates from the 13th or 14th century. Direct measurements of the skull according to Martin's technique and computed tomography (CT) were made. The skull is from a male whose age was estimated as 40–55 years. In the nasal cavity, a large bony formation with the appearances of a tumor, a lesion of the maxillary sinus wall, and a significant curvature of the nasal septum were found. The CT scan demonstrated changes that could be described as a type IV concha bullosa, according to Krzeski's classification. This anatomical variation was first described by Zuckerkandl in 1893. The symptoms that were often associated with concha bullosa include nasal obstruction or congestion, facial pain, and headache. Concha bullosa can result in recurrent sinusitis, mucocele, or mucopyocele. In the case of the Głogów skull, an extensive lesion and inflammatory changes in the maxillary sinus and destruction of the orbital floor suggests the presence of a mucopyocele that arose from a concha bullosa.

Population affinities of Parsis in the Indian subcontinent

The present study was an attempt to document changes in frequencies of dental morphology traits and understand phenetic affinities of Parsis, who migrated to the Indian subcontinent around the 8th century. Despite successfully integrating themselves into the Indian society, they have retained their ethnicity and distinct cultural practices. This study was conceived as a result of an excavation at the site of Sanjan, Gujarat which, as per historical records, is believed to be the first town in the Indian subcontinent with a large Parsi settlement thereby facilitating a diachronic comparison between the ancestral and extant Parsi groups. We compared and analysed dental traits between the two groups expecting a very close relationship between them owing to their ancestor–descendent relationship. Eleven discrete dental traits were selected and scored using the Arizona State University Dental Anthropology System (ASUDAS). Frequency changes were assessed by comparing trait frequencies; whereas phenetic affinity between Parsis was assessed by statistically comparing them with 13 populations using Smith's mean measure of divergence (MMD) statistic. Comparison of dental trait frequencies between Sanjan and extant Parsi samples show significant differences in incisor morphology, Carabelli cusp and Hypocone development. Trait frequencies, MMD values and 2D multidimensional scaling (MDS) plot indicate that extant Parsis and Sanjan samples are distantly separated from each other. Extant Parsis show closer affinity to low caste Mahars and tribal Madia Gonds than South and Central Asian groups. Sanjan is distant from all other groups including extant Parsis. It is likely that genetic drift accentuated by their small numbers and strict endogamy has resulted in divergence of Parsi groups. Similarly, their convergence with Maharashtran groups indicates admixture of Parsis with local groups, which supports earlier conducted mtDNA studies. Copyright © 2009 John Wiley & Sons, Ltd.     

The Process of Kinship in the Paternal/Fraternal House of the Austronesian‐speaking Amis of Taiwan

In this essay, I will describe the traditional social organisation of the Amis peoples of Taiwan which previous ethnographers have portrayed as consisting of a matrilineal clan‐based system conjoined with a residential‐based male age‐set/grade system. Following David Schneider's critique of ‘kinship’ cross‐culturally and the ‘new kinship studies' which his work inspired, I will attempt a reinterpretation of overall Amis social organisation as instead a total kinship‐based system comprised of a paternal/fraternal system which integrates and encompasses the multiplicity of maternal‐focused houses constitutive of village communities. Rather than being a system composed of kinship and non‐kinship parts, I argue that Amis social organisation is comprehensively kinship‐based. Moreover, I shall describe how through paternal/fraternal relations generated by rites of male initiation and rebirth this overall integration of diverse matrifocal units is achieved. In the first section, I will describe the structure of the paternal/fraternal initiatory system. In the following section, I will draw upon the major anthropological theories of initiation including rites of passage and the literature on sacrifice to describe numerous aspects of initiation activities, showing how the classificatory father‐son and elder‐younger‐brother relations between and within the initiation sets are explicitly represented by the concepts and practices of the Amis.     

Ancient DNA in archaeological wheat grains: preservation conditions and the study of pre-Hispanic agriculture on the island of Gran Canaria (Spain)

The recovery of ancient DNA from archaeological wheat samples under different preservation conditions was assessed using a number of genetic markers. It was possible to amplify nuclear DNA from desiccated grains but not from charred. The desiccated grain was from a pre-Hispanic grain silo in Gran Canaria and showed excellent DNA preservation, enabling the amplification of the ribosomal DNA markers IGS and ITS, the upstream region of the HMW-glutenin locus and single-locus nuclear microsatellites. Our results demonstrated the presence of both durum and bread wheat in an assemblage of naked grain. We were also able to identify different genotypes in durum wheat and compare these with extant landraces, providing insights into the agrarian practices of the ancient Canarians and the origin of their crops.     

An Umm an‐Nar culture stone bas‐relief from Al‐Qutainah,Sultanate of Oman

The Al‐Qutainah stone with its bas‐relief decoration was found in a secondary position, reused through time. The object is clearly a facing stone, originally part of an Umm an‐Nar period tomb, and was subsequently repeatedly reused for making new engravings. While working out the sequence of images it became clear that the very first image was a pair of human figures. This artwork is associated to grave architecture and therefore dates to the Umm an‐Nar period. Two models of interpretation can be suggested, the image of a human pair or the image of a supplicant and deity. Changes in the original meaning of the image indicate conceptual changes in subsequent periods, most probably alterations in the underlying social structure. The importance of the Qutainah stone is not solely due to rare monumental human figurative expression of the period in Oman; furthermore, the find spot in the Adam region is at a distance from the central location of Umm an‐Nar culture that has so far emerged.     

Regional Inequality in the EU: How to Finance Greater Cohesion

After outlining the overall scale and evolution of European Union (EU) public expenditure, this paper examines the mechanisms driving the allocation of Cohesion Policy resources. The analysis reveals the extent to which the outcome of the policy's principle- and formula-driven allocation mechanisms is modified by precedent and politico-economic considerations. In particular it shows that the consequent per capita final financial allocations (the intensity of aid) are greatest not for the poorest areas: up to 84% of EU GDP per head, aid increases as income increases. The analysis also emphasizes the on–off nature of the EU policy. In the light of these results a series of simulations are carried out. Attention is given first to a more economically sensitive treatment of transition regions, whose relative growth results in shifts from one category to another and to a mechanism capable of providing differentiated support to all disadvantaged regional economies. Attention is then given to ways of ensuring that final allocations are inversely proportional to income, and that most aid is concentrated on the most disadvantaged areas (Section 5). In the conclusions attention is paid to guidelines which might apply to the reform of the EU Cohesion Policy.     

Are new patterns of low‐income distribution emerging in Canadian metropolitan areas?

Recent studies on urban poverty in Canadian cities suggest a growing spatial concentration of poor populations within metropolitan regions. This article assesses trends in the intra‐urban distribution of the poor population from 1986 to 2006 in eight of Canada's largest cities. We consider five well‐known dimensions of segregation, as identified by Massey and Denton (1988) , in order to examine changes in the spatial distribution of poor populations within metropolitan areas: evenness, exposure, concentration, clustering, and centralization. These indices were calculated for low‐income populations at the census tract level using data from five Canadian censuses. Although each metropolitan area has distinctive characteristics, we were able to identify some general trends. The results suggest that, in 2006 compared to 1986, low‐income populations lived in more spatially concentrated areas, which were, at the same time, socioeconomically more homogeneous and more dispersed throughout the metropolitan area. In addition, we observed that over the last twenty years areas of poverty have been located, for the most part, in neighbourhoods adjacent to downtown cores. Nevertheless, we found that poverty has mostly increased in suburban areas located outside inner‐city neighbourhoods. Growing socioeconomic homogeneity and dispersion of low income areas in metropolitan areas reveal new spatial patterns of urban poverty distribution. These findings should be cause for concern as social isolation in the most disadvantaged neighbourhoods could affect the life chances and opportunities for the residents of those areas.
