In colonial America, land acquired new liquidity when it became liable for debts. Though English property law maintained a firm distinction between land and chattel for centuries, in the American colonies, the boundary between the categories of real and personal property began to disintegrate. There, the novelty of easy foreclosure and consequent easy alienation of land made it possible for colonists to obtain credit, using land as a security. However, scholars have neglected the first instances in which a newly unconstrained practice of mortgage foreclosure appeared—the transactions through which colonists acquired land from indigenous people in the first place. In this article, I explore these early transactions for land, which took place across fundamental differences between colonists’ and native communities’ conceptions of money, land, and exchange itself. I describe how difference and dependence propelled the growth of the early American contact economy to make land into real estate, or the fungible commodity on the speculative market that it remains today. 相似文献

Certified aircraft mechanics represent the largest gender-based demographic disparity in aviation with a 49-to-1 male-to-female ratio. Recent research into women’s perspective on the aircraft mechanic career field revealed that a large majority of women felt unsure or negatively about their potential promotion opportunities and social acceptance. The purpose of this follow-on mixed-methods concurrent triangulation study was to explore the perspectives of men regarding the aforementioned topics to see if they differ from previously published research on women perceptions. A total of 587 men and 431 women completed an eight-question survey containing 5-point Likert-type and open-ended questions. The quantitative comparison consisted of the total 1018 responses, while only the survey responses from the 587 men were analysed for correlations and qualitative codes. Results indicated that there was a significant difference between the perceptions of men from those of the women regarding work environment safety and social acceptance. Additional correlation analysis revealed social acceptance to be a key variable when predicting career appropriateness, advancement opportunity and work environment safety. The 587 qualitative responses yielded results that differed from those of women, citing an assumption that women have the same advancement opportunities or be as socially accepted as men entering the field. 相似文献

THESIS: Despite spending more on medical care than any other country in the world, the United States still boasts some of the worst patient outcomes of any developed nation. This disparity is especially true of how Americans give birth and die. These natural human transitions have become catastrophically expensive and leave patients and their families traumatized from unnecessary interventions. This article examines the costs and outcomes associated with the medicalization of birth and death and argues that alternatives exist that improve patient outcomes while lowering costs. Access to these alternatives will require changing current regulatory and reimbursement structures and providing trained support staff to help families navigate beginning- and end-of life decisions. 相似文献
