The interaction among myriad species and chemicals in the food chain often yields potential outcomes which are difficult to foresee. In policy terms, these interactions comprise an information load beyond human cognition, resulting in unexpected side effects. The clearest examples are seen in the invasions of species and epidemics, air pollution, toxic substances, and endangered species. The policy process attempts to deal with the information problem by using (1) an incremental approach, (2) a bounding approach, or (3) an uncertainty approach. Unfortunately, the bounding approach excludes all data on interactions outside the apparent cause/effect hypothesis. Possible approaches to augment and improve environmental policy, beyond the bounding approach, are to inquire into uncertainties and side-effects, choose complex ecologies over simple ones, and sample for uncertain risks by probability assessments.  相似文献

Inflation may be looked upon as a deferred consumption tax which reduces consumer purchasing power through high prices to compensate for earlier excess expansions of credit. A portion of this excess borrowing is by government to finance deficits. The inflation cost may then be compared by family–income class with the alternative income taxes needed to avoid inflation by eliminating the deficits. By this calculation for 1965–75, the inflation cost was highly regressive, with an effective rate of 17 percent on. families below $5,000, and 17 times greater than such families would have had to pay in income taxes. Meantime, the effective inflationary tax rate for wealthy families over $50,000 in income was a bonus, or tax rebate, of one percent.  相似文献

FEELING IS BELIEVING, OR LANDSCAPE AS A WAY OF BEING IN THE WORLD   总被引:3,自引:2,他引:1  
This article is work‐in‐progress, an orientation of thought towards possibilities for individual human beings to diminish the distance between outer and inner landscapes imposed by cultural norms and happenstances such as exile. The dominance of visual landscapes and visual perceptions is seen as a pivotal problem, to be solved by the engagement of all the senses in landscape discourse and formation. All the senses are engaged in earliest childhood, as they have been in ‘primitive’ societies. While returning to either a state of childhood or primitivism is an impossible dream, it is possible to edge closer to human nature by engaging and honing all the senses, especially the ‘earth‐bound senses’ of feel, smell and taste. Cultivating those senses and developing discourse about them, and incorporating them into landscape formation and enjoyment, is much more difficult than having a discourse about sight and hearing, for which there is a rich and well‐developed symbolic language and which can be shared through various types of media. The way towards a deeper discourse about the earth‐bound senses, and the way out of the tyranny of the visual, is to be found in stories, as several thinkers suggest. The story told is autobiographical and literary – a mode of geographic writing that I developed in a 2004 book (Bunk?e 2004a), in which the complex dilemmas of home and road were explored. This article shows how in the early 1970s I defined the individual's landscape as ‘a unity in one's surroundings perceived through all the senses’, with imagination as the key human faculty. And I tell the story of how through complex circumstances, a visually and emotionally repugnant landscape became emotionally and intellectually attractive, with a scent, not a picture or image causing the initial attraction. The external and internal landscapes are thus unified, resulting in a sense of timelessness and placelessness of deep existential significance for the person.  相似文献

Environment and development practitioners increasingly are interested in identifying methods, institutional arrangements and policy environments that promote negotiations among natural resource stakeholders leading to collective action and, it is hoped, sustainable resource management. Yet the implications of negotiations for disadvantaged groups of people are seldom critically examined. We draw attention to such implications by examining different theoretical foundations for multistakeholder negotiations and linking these to practical problems for disadvantaged groups. We argue that negotiations based on an unhealthy combination of communicative rationality and liberal pluralism, which underplays or seeks to neutralize differences among stakeholders, poses considerable risks for disadvantaged groups. We suggest that negotiations influenced by radical pluralist and feminist post‐structuralist thought, which emphasize strategic behaviour and selective alliance‐building, promise better outcomes for disadvantaged groups in most cases, particularly on the scale and in the historical contexts in which negotiations over forest management usually take place.  相似文献
