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

Les fouilles de James Matthews. Second rapport prelimhaire P. BAKER AND G. HENDERSON Les auteurs décrivent dans ce rapport les méthodes utiliées et les résultats obtenus en 1975–77, sur une épave coulée par faible fond sur la côte ouest d'Australie. Ils présentent, en détail, l'utilisation d'un carroyage rigide, facilement manoeuvrable et servant en même temps de plate-forme pour une tourelle - photo pyramidale. Les avantages et les limites de la photogrammétrie, pour les relevés subaquatiques, sont aussi exposés. 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.1 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.”2 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.3 相似文献
