In Canada, as in other industrialized welfare states, definitions of health system sustainability reflect different goals and correspondingly diverse ways of understanding exactly what is to be sustained and how. In this article, we report on results from a survey of documents and groups involved in and/or concerned about sustainability of the healthcare system. We identify four broad narratives of sustainability in Canadian healthcare reform discourse, and explore what these different sustainability narratives tell us about the character and contours of these often‐fractious debates. We argue that sustainability itself may not be a paradigm shift, as has been suggested, but a plot device that helps to steer the story in a particular direction, ‘black‐boxing’ certain aspects of context and emphasizing others.  相似文献

The author used a new longitudinal data set, the How Couples Meet and Stay Together surveys (N = 3,009), to generate the first nationally representative comparison of same‐sex couple stability and heterosexual couple stability in the United States. He measured the association between marriage (by several definitions of marriage) and couple longevity for same‐sex couples in the United States. Reports of same‐sex relationship instability in the past were due in part to the low rate of marriages among same‐sex couples. After controlling for marriage and marriage‐like commitments, the break‐up rate for same‐sex couples was comparable to (and not statistically distinguishable from) the break‐up rate for heterosexual couples. The results revealed that same‐sex couples who had a marriage‐like commitment had stable unions regardless of government recognition. A variety of predictors of relationship dissolution for heterosexual and for same‐sex couples are explored.  相似文献

In this paper we compare several types of economic dependency ratios for a selection of European countries. These dependency ratios take into account not only the demographic structure of the population, but also the differences in age-specific economic behaviour such as labour market activity, income and consumption as well as age-specific public transfers. In selected simulations where we combine patterns of age-specific economic behaviour and transfers with population projections, we show that in all countries population ageing would lead to a pronounced increase in dependency ratios if present age-specific patterns were not to change. Our analysis of cross-country differences in economic dependency demonstrates that these differences are driven by both differences in age-specific economic behaviour and in the age composition of the populations. The choice of which dependency ratio to use in a specific policy context is determined by the nature of the question to be answered. The comparison of our various dependency ratios across countries gives insights into which strategies might be effective in mitigating the expected increase in economic dependency due to demographic change.  相似文献

The internet and other digital networks in the U.S. (and beyond) remain essentially an upgrade of the national telephone network built by AT&T over the first half of the twentieth century, and digital payment remains tethered to telephony at the level of infrastructure. Telephone history also continues to inform digital payment at the level of interface. Debit card readers feature a keypad nearly identical to those introduced (also by AT&T) to the dialling public a half-century ago on touch-tone telephones. In this essay I highlight the development of the touch-tone keypad as a transformative payment technology. There have been three great leaps forward in the history of telephone interface: the dial, the keypad and the touch screen. Each corresponds to a period of technological transformation in the telephone industry and society more broadly: the rotary dial and automation, touch-tone keypads and digitization, and touch screens and computerization. The successful careers of the dial and the keypad, especially when read in tandem, suggest that touch screens will alter the everyday economics of retail payment even more radically than its predecessors. I also describe a broader trajectory of digital naturalization, whereby telephone numbers have proliferated into a personal identification number, passwords and a plethora of personalized information. Payments increasingly circulate today as subsets of personal information within the vast sea of big data. Payment apps are demonstrating a capacity to reorganize retail transactions on a scale as vast as any technology since the cash register. The history of retail payment finds the point of sale heading from the till into shoppers’ pockets. As a result, consumers are increasingly shouldering the costs of purchasing, maintaining, upgrading and securing the technology used for everyday transactions.  相似文献
