The 1970's has been a period in which three trends have coincided: housing prices have been escalating, wives have continued to enter the labor force, and legislation prohibiting discrimination in mortgage markets on the basis of sex and marital status has been enacted. In this paper, we examine the role of the two-earner family–one in which both husband and wife work–in the housing market of the 1970's, and the interrelation of this household type with other factors shaping the current high demand for housing. We also speculate on the role of the two-earner family in the housing market of the 1980's. We conclude that two-earner families are in a position to increase their housing outlays in the future, that the continued growth in the number of two-earner families will add to future housing demand, but that many two-earner families may be divorced couples of the future. This suggests that, while there will be a strong impact on single-family home demand, there will also be some restructuring of demand toward rental housing and cooperative/condominium ownership.  相似文献

Shell beads are well established in the archaeological record of sub-Saharan Africa and appear as early as 75,000 BP; however, most research has focused on ostrich eggshell (OES) and various marine mollusc species. Beads made from various land snails shells (LSS), frequently described as Achatina, also appear to be widespread. Yet tracking their appearance and distribution is difficult because LSS beads are often intentionally or unintentionally lumped with OES beads, there are no directly dated examples, and bead reporting in general is highly variable in the archaeological literature. Nevertheless, Achatina and other potential cases of LSS beads are present at over 80 archaeological sites in at least eight countries, spanning the early Holocene to recent past. Here, we collate published cases and report on several more. We also present a new case from Magubike Rockshelter in southern Tanzania with the first directly dated LSS beads, which we use to illustrate methods for identifying LSS as a raw material. Despite the long history of OES bead production on the continent and the abundance of land snails available throughout the Pleistocene, LSS beads appear only in the late Holocene and are almost exclusively found in Iron Age contexts. We consider possible explanations for the late adoption of land snails as a raw material for beadmaking within the larger context of environmental, economic, and social processes in Holocene Africa. By highlighting the existence of these artifacts, we hope to facilitate more in-depth research on the timing, production, and distribution of LSS beads in African prehistory.  相似文献

Sexual assault is a heinous crime that for decades had failed to receive needed attention on college campuses across the country.11. Nancy Chi Cantalupo, “Burying Our Heads in the Sand: Lack of Knowledge, Knowledge Avoidance, and the Persistent Problem of Campus Peer Sexual Violence,” 43 Loy. U. Chi. L.J. (2011) 205, 214–17.View all notes That changed on April 4, 2011, when the Department of Education's (ED) Office of Civil Rights (OCR) issued a “Dear Colleague” letter (DCL) on sexual harassment and violence, which purported to clarify “Title IX's requirements related to student-on-student sexual harassment, including sexual violence, and explains schools' responsibility to take immediate and effective steps to end sexual harassment and sexual violence.”22. Russlynn Ali, Assistant Secretary for Civil Rights, “Dear Colleague Letter from Assistant Secretary for Civil Rights,” Office for Civil Rights, U.S. Department of Education.

All subsequent references to this letter will refer to Ali, Sexual Assault Guidance, 2011.View all notes The intent of the letter to mete out swift justice for sexual assault survivors and to punish perpetrators and negligent institutions became immediately clear as the number of schools under OCR investigation began to swell. In response, colleges and universities have instilled a vast machinery of administrative procedures to adhere to the new requirements. At last count the OCR was conducting more than 300 investigations of nearly 200 colleges and school districts for the handling of sexual harassment and assault under Title IX.33.

This article analyses processes of uneven urbanisation by looking at flood infrastructure. Combining the conceptual frameworks of uneven development with the political ecology of urbanisation, we use flood infrastructure as a methodological device to trace the processes through which unevenness occurs within, but also far beyond, the city of Jakarta, Indonesia. We do this to show how the development of flood infrastructure in Jakarta is shaped by the logic of capitalism through mutually implicated tendencies of socionatural differentiation and equalisation. These processes render waters, resources and labour as similar across places and times to produce different spaces for different populations, within and beyond city boundaries. This theorisation reveals how the urban inequalities (re)produced by flood infrastructure are intimately linked to inequalities (re)produced through the urbanisation of the non‐city.  相似文献

Bell, P.R., Burns, M.E. & Smith, E.T. October 2017. A probable ankylosaurian (Dinosauria, Thyreophora) from the Early Cretaceous of New South Wales, Australia. Alcheringa 42, 120–124. ISSN 0311-5518.

We describe an isolated osteoderm from the Albian Griman Creek Formation where it is exposed near the town of Lightning Ridge in central-northern New South Wales, Australia. Several lines of evidence allow referral of this element to the Ankylosauria—a group that epitomises body armour and ubiquitous osteodermal coverage among dinosaurs. Despite the abundant record of fossil vertebrates from this interval, ankylosaurians have not been previously reported, although, they have been described from penecontemporaneous deposits in western Queensland and Victoria. This discovery, therefore, provides an important link between the northerly faunas (including the Griman Creek Formation) that flourished at the edge of the epeiric Eromanga Sea, with those from the sub-polar rift-valley system of Victoria during the mid-Cretaceous.

Intensive farming is an increasing part of Australian agriculture, including in the multi‐functional landscapes at the edges of Australian cities. The example of intensive “broiler” poultry production reveals the tensions that arise when sites of hyper‐productivity conflict with social change in rural areas. Planning processes for intensive farming in the Australian state of Victoria are predicated on stability and consensus: on assumed static and uncontroversial ideas of agriculture, its place, and the primacy of agricultural productivity. Yet concerns about the industrialisation of agriculture are live political issues at the local level, especially in dynamic peri‐urban locations. This paper explores the emergence of a politics of place outside the bounds of planning consensus through an analysis of planning appeals and associated media relating to planning permits for intensive poultry developments in Victoria over 2011–2016. We highlight tensions that exist in relation to technical planning assessments and categorisations used to assert farming as the orthodox use of rural land, especially when new forms of farming look and feel demonstrably different. Using Mouffe's problematising of the negation of antagonism and Rancière's notion of the risks of a false consensus democracy, we argue that planning processes for intensive farming illustrate critical issues in participatory planning. While ostensibly post‐political decision‐making narrows the politics of place and food systems to decisions about policing the boundaries and buffer distances placed around intensive poultry developments, alternative representations of rural life persist. The certainty offered by code‐based planning does not negate the ongoing (if inconvenient) politics of intensive peri‐urban agriculture.  相似文献

Bells were an inescapable part of fourteenth-century urban life. They signalled the hours of the day and times for prayers; they warned of tempests and enemy armies; they heralded masses, funerals, and deaths. The pealing of bells brought men, women, and children together, choreographing communal behaviour in time and space. Bells echoed the vox Domini, calling out the deaths of holy men and women, celebrating the working of miracles. The ubiquitous presence of bells reflected the omnipresence of God in the medieval world. Their echoes transformed private moments into collective experiences, elevating the mundane into the miraculous. Scholars have rarely examined the religious aspects of bells, looking instead at their more practical side, especially their utilisation as markers of time and the allegedly concurrent rise of mercantile culture. This article approaches bells from the viewpoints of those men and women who heard them and wanted them rung. Focusing on sources from Christian clerics, we see that medieval men rang the bells with clear, but many possible, purposes in mind. By marking time and prayers, Christian church bells helped to create and facilitate communities within dioceses, spurring and choreographing their actions. During funerals, bells broadcast private moments, giving them communal significance. The transformative, creative function of bells is clearest in their role in miracles. In Manresa, the vision experienced by a few became a community affair when the church bells gathered the people; the bells transformed an ordinary day into one where the people, as a community, received divine favour. Finally, with the deaths of holy persons, the tolling of bells transformed private, even anonymous deaths, into moments of wonder as God’s hand touched the world.The pealing of bells defined Christian communities in the Mediterranean and, at the same time as rulers and elites throughout the region were seeking to control minority groups, those same groups were seeking to exercise control over the sounds within their own communities. Through the pealing of bells, churchmen across Catalunya sought to direct the thoughts and prayers of their listeners. When the Christian clerics of Catalunya rang their churches’ bells, they had specific aims in mind, yet, as the evidence demonstrates, the pealing of the bells never meant just one thing. This article demonstrates that there is much more to understanding medieval bells than knowing ‘for whom the bell tolls’; we have to look at the listeners as much as the ringers in order to understand their cultural significance in medieval Europe. This article is a first step in how such a study could be begun.  相似文献
