We use regression and factor analyses to explain intermetropolitan variation in the proportion of jobs in disaggregated service sectors in American metropolitan areas. Central place theory postulates of centrally located establishments serving a surrounding complementary region partially explain the positive relationship between metropolitan size and the proportion of jobs in an area in services. Regional variation in demand following several decades of substantial shifts in population and economic output is an additional influence. Intermetropolitan clustering of service sectors is also occurring. A factor analysis of employment proportions in twenty-two disaggregate service sectors identified five intersectoral service clusters. The factor analysis accounted for substantially more variance than the regression equations. We interpret this result as evidence of the emergence of service-based spatial industrial complexes. We argue that agglomeration of information-intensive intermediate services is driven by an attraction to labor markets endowed with pools of skilled professionals who can flexibly apply their talents in a variety of sectors. Unusual demographic characteristics of some metropolitan areas probably explain clusters of final demand services.  相似文献

This article examines imaginings and uses of place in the city of Belfast which challenge the conventionally gendered and sectarian place discourses dominating politics and society in Northern Ireland. These alternative imaginings are articulated in two artworks, ‘Home’, by Mary McIntyre, and ‘Street Signs’, by Aisling O'Beirn. I present readings of these pieces with reference to concepts of public and private which signify through socio-political, geographical and psychological orderings of space. Focusing on the construction of public and private space allows me to approach the issue of sectarian territorialisation in Belfast obliquely, while recognising its physical and psychological potency and the complexity of its operations; further, it facilitates the exploration of how gender and memory are made to matter spatially, in general and specifically in Belfast. This analytical perspective clarifies certain exclusions and oppressions inherent in the framing of space, but also offers understandings of how these may be destabilised, allowing unorthodox or marginal identities and practices to emerge as co-constituents of space.  相似文献

The small mineral-binding bone protein, osteocalcin, has been applied in a number of studies on ancient bone due to predictions of its long-term stability. However, the intact protein has not been shown to survive in ancient bone devoid of DNA, which is a much more phylogenetically informative biomolecule. In this investigation, the survival of osteocalcin is directly compared to the amplification of mtDNA in a set of 34 archaeological samples from four sites throughout Europe. We also present unpublished osteocalcin sequences of seven mammalian species in addition to the 19 published sequences to highlight phylogenetic limitations of this protein. The results indicate that the intact osteocalcin molecule survives less in archaeological samples than mtDNA and is more subject to the temperature of the archaeological site. Amino acid analyses show the persistence of the dominant protein collagen in samples that failed both osteocalcin and mtDNA analyses. The implications these findings present for biomolecular species identification in archaeological and palaeontological material are that, although proteins do survive beyond ancient DNA, osteocalcin does not appear to be the most ideal target.  相似文献

The centenary of the Easter Rising in 2016 and the 150th anniversary of James Connolly’s birth in 2018 afford an ideal opportunity to reappraise this unique figure. Rightly renowned for his polemical journalism and political theory, Connolly is less celebrated for his creative writing. His 1916 play, Under Which Flag?, long considered lost, resurfaced fifty years ago without causing significant ripples in Irish literary circles, but interest in Connolly’s role in the struggle for Irish independence continues to grow, and critics are becoming increasingly aware of the fusion of feminist and socialist thought that shaped his particular anti-imperialist agenda. In this context his creative writing takes on new significance. A second lost play of Connolly’s, The Agitator’s Wife, has never been found, but its discovery would surely deepen our understanding of this gifted radical thinker. In this essay we suggest that an anonymous short story bearing that very title, published in a short-lived Christian socialist journal of the 1890s, may be a crucial missing piece in solving the puzzle of Connolly’s forgotten drama.  相似文献
