Off‐farm labour decisions of a sample of Kansas farmers are evaluated. The central question of our analysis pertains to whether 1996 US farm policy reforms may have altered the decisions to work off the farm. The effects of policy decoupling on off‐farm labour are complex: different aspects of policy changes can have opposing effects on off‐farm work decisions. Essentially, this makes this issue an empirical question. Results show that the introduction of fixed, decoupled payments in 1996 might have reduced the likelihood of off‐farm labour participation. However, the new policy environment may have increased farm households’ revealed aversion to risk, motivating a higher participation in non‐farm labour markets. The effects of 1996 policy reforms on farm income variability could have been attenuated by changes in US crop insurance programmes and by an increase in emergency assistance payments towards the end of the 1990s. The reduction in price supports may have increased the motivation for working off the farm. The net effect of the overall reforms on off‐farm work participation is not likely to have been large.  相似文献

While technology and health care delivery are inextricably and increasingly intertwined and technology has driven major advances in quality and efficiency in health care, technology does not replace the need for a thinking human being in care delivery. The term "technicity" refers to the tension created by the ability of humans to think versus their risk of being exploited as objects subservient to technologies. Drawing upon the philosophical works of Thoreau, Heidegger, and others, the authors pause on the conundrum created by expanding technology with the assumption that technological "improvements" should be evaluated with caution. Health care information systems are an example of tools that have improved our ability to collect and store information, but when systems "go down," staff can be rendered helpless. Similarly, technology can impose personal distance between the patient and provider in instances where staff are positioned as a mechanism for collecting data rather than a person interacting with another person. In some cases, health care providers function as navigators helping patients reach the correct pharmaceutical, rather than as teachers helping patients seek better health. Lastly, the tendency toward systems analysis in the context of the complex hospital environment leads solely toward uniform solutions rather than instances where a customized solution is warranted.  相似文献

This article measures the size and incomes of six major social classes across the industrial revolution using social tables for England and Wales in 1688, 1759, 1798, 1846, and 1867. Lindert and Williamson famously revised these tables, and this article extends their work in three directions. First, servants are removed from middle‐ and upper‐class households in the tables of King, Massie, and Colquhoun and tallied separately. Second, estimates are made for the same tables of the number and incomes of women and children employed in the various occupations, and, third, incomes are broken down into rents, profits, and employment income. These extensions to the tables allow variables to be computed that can be checked against independent estimates as a validation exercise. The tables are retabulated in a standardized set of six social groups to highlight the changing structure of society across the industrial revolution. Gini coefficients are computed from the social tables to measure inequality. These measures confirm that Britain traversed a ‘Kuznets curve’ in this period. Changes in overall inequality are related to the changing fortunes of the major social classes.  相似文献

This article develops a posthuman approach to authorship to challenge implied distinctions and superiorities between the social and material worlds, which can detach academics and their writing from societies and ecosystems. By reimagining academic texts that are open for richer interpretation and accessible to diverse audiences, this article offers two main contributions. Firstly, I develop a conceptualisation of the posthuman author as an 'unbounded gatherer', adding to others' attempts to destabilise predominant humanistic ways of writing about managing and organizing that view authors as autonomous agents. Secondly, by developing the idea of 'mediators' as a means to explore how the sociomaterial is implicated in writing, debates about materiality in writing are extended. Through an illustration of posthuman writing, five emergent categories of mediators are analysed, and three textual practices are performed and examined.  相似文献

传统上,金融系统主要有两种形式,一种是以银行为基础的,另一种是以市场为基础的。它们的有效性需要从几个方面来比较,包括风险分担、信息供给、资助新兴产业、法人治理、法律、政治对金融的影响。这两种金融系统各有利弊。就其稳定性来讲,它们都会遭受经济危机的危害。展望未来的金融系统,应该是以金融中介和市场共为基础,具有很多的优点而几乎没有缺陷。  相似文献
