It is becoming increasingly clear that scientists, managers, lawyers, public policymakers, and the public must decide how to value what is provided by, and is a consequence of, natural resources. While “Western” scientists have clear definitions for the goods and services that ecosystems provide, we contend that these categories do not encompass the full totality of the values provided by natural resources. Partly the confusion results from a limited view of natural resources derived from the need to monetize the value of ecosystems and their component parts. Partly it derives from the “Western” way of separating natural resources from cultural resources or values, and partly it derives from the false dichotomy of assuming that ecosystems are natural, and anything constructed by man is not natural. In this article, we explore the previous assumptions, and suggest that because cultural resources often derive from, and indeed require, intact and unspoiled natural ecosystems or settings, that these values are rightly part of natural resources. The distinction is not trivial because of the current emphasis on cleaning up chemically and radiologically contaminated sites, on restoration of damaged ecosystems, on natural resource damage assessments, and on long‐term stewardship goals. All of these processes depend upon defining natural resources appropriately. Several laws, regulations, and protocols depend upon natural resource trustees to protect natural resources on trust lands, which could lead to the circular definition that natural resources are those resources that the trustees feel they are responsible for. Where subsistence or tribal peoples are involved, the definition of natural resources should be broadened to include those ecocultural attributes that are dependent upon, and have incorporated, natural resources. For example, a traditional hunting and fishing ground is less valued by subsistence peoples if it is despoiled by contamination or physical ecosystem degradation; an Indian sacred ground is tarnished if the surrounding natural environment is degraded; a traditional homeland is less valued if the land itself is contaminated. Our argument is that intact natural resources are essential elements of many cultural resources, and this aspect requires and demands adequate consideration (and may therefore require compensation). 相似文献

Daniel Rigney 《Sociological inquiry》1991,61(4):434-451
Hofstadter's landmark analysis of anti-intellectualism in American life is interpreted within the framework of the sociology of knowledge. His analysis suggests three analytically distinct types of anti-intellectualism: religious anti-rationalism, populist anti-elitism, and unreflective instrumentalism. Each type arises from within its own distinctive institutional matrix. Although Hofstadter fails to anticipate the growing cultural impact of mass media institutions, he demonstrates convincingly that anti-intellectualism is not a unitary phenomenon. 相似文献

Two earner family migration A search theoretic approach 总被引:1,自引:0,他引:1
Mont D 《Journal of population economics》1989,2(1):55-72
This paper represents the first attempt to model the two earner family decision to migrate using a joint search theoretic approach. In so doing, the paradox of a couple whose members would both migrate if single but decide not to migrate because they are married to each other is discovered and explained. Furthermore the impact of the rising number of working women and reentry of wives into the labor force on the extent and regional pattern of migration is discussed. Extensions to the model are addressed, as well as future avenues of research, both theoretical and empirical. It is suggested that the search theoretic approach, not previously applied to models of family migration, is the most appropriate. 相似文献

This article focuses on a Russian woman entrepreneur who established a very successful software firm under license from an American software company. The case illustrates a productive and successful partnership between a Western company and a new Russian entrepreneur. Recent developments in Russian entrepreneurship are reviewed, and the selection of Russian entrepreneurs as business partners is evaluated. The American company is described briefly, followed by an in-depth discussion of its Russian partner and founder, Olga Kirova. Conclusions and interpretations are offered on choosing the right Russian partners, assessing their personal values, objectives and leadership skills, being a good Western business partner, and considering Russian women as business associates. 相似文献

Although a consistent body of research has demonstrated that occupational segregation is highly consequential for women's economic standing, we know little about the processes that contribute to changes in levels of sex segregation. In this study, we examine those factors that contribute to changes in the percent of women in detailed occupational categories in the United States. Since we are most concerned with the economic consequences of this type of segregation, we analyze a group of high-paying, male-dominated occupations that, if better integrated, would contribute most to earnings equality. We find that occupations to which relatively high percentages of women aspired and occupations that are growing have been experiencing above-average increases in the percentage of women, while occupations characterized by male-stereotyped task profiles have been witnessing below-average increases. Additionally, our results suggest the presence of a ceiling effect: it is easier for women to break into male-dominated occupations initially than to sustain growth. Our analysis suggests that both supply and demand-side explanations provide insight into the processes contributing to increases in the occupations that we examine, although it can be very difficult to distinguish between supply and demand-side elements; indeed they may occur simultaneously. 相似文献
