Extreme environmental situations are useful tools for the investigation of the general processes of adaptation. Among such situations, high altitude of more than 3000 m produces a set of pathological disorders that includes both cerebral (cAS) and respiratory (RAS) altitude symptoms. High altitude exposure further induces anxiety responses and behavioural disturbances. The authors report an investigation on anxiety responses, personality traits, and altitude symptoms (AS) in climbers participating in a 31-day period of confinement and gradual decompression in a hypobaric chamber equivalent to a climb from sea-level to Mount Everest (8848 m altitude). Personality traits, state-trait anxiety, and AS were assessed, using the Cattell 16 Personality Factor questionnaire (16PF), the Spielberger's State-Trait Anxiety Inventory (STAI), and the Lake Louise concensus questionnaire. Results show significant group effect for state-anxiety and AS; state-anxiety and AS increased as altitude increased. They also show that state-type anxiety shows a similar time-course to cAS, but not RAS. Alternatively, our results demonstrate a significant negative correlation between Factor M of the 16PF questionnaire, which is a personality trait that ranges from praxernia to autia. In contrast, no significant correlation was found between personality traits and AS. This suggests that AS could not be predicted using personality traits and further support that personality traits, such as praxernia (happening sensitivity), could play a major role in the occurrence of state-type anxiety responses in extreme environments. In addition, the general processes of coping and adaptation in individuals participating in extreme environmental experiments are discussed.  相似文献

The aim of this article is to further our understanding of the “GM is unnatural” view, and of the critical response to it. While many people have been reported to hold the view that GM is unnatural, many policy-makers and their advisors have suggested that the view must be ignored or rejected, and that there are scientific reasons for doing so. Three “typical” examples of ways in which the “GM is unnatural” view has been treated by UK policy-makers and their advisors are explored. These are the Government’s position (DEFRA Report), the account of the Nuffield Council on Bioethics, and the position of Nigel Halford, a scientist with an advisory role to the Government. I show that their accounts fail to mount a convincing critique. Then, I draw on an empirical research project held during  2003–2004 at the University of Newcastle-upon-Tyne in the north east of England. Scientists met with non-scientists in a range of facilitated one-to-one conversations (“exchanges”) on various environmental issues, one of which was on GM. Our findings show that some scientists who rejected the “GM is unnatural” view struggled to do so consistently. Their struggle is interpreted in terms of a conflict between a so-called “scientific” worldview, and a different worldview that underlies the concerns of those who held the “GM is unnatural” view. This worldview is explored further by an examination of their concerns. What distinguishes this worldview from the “scientific” worldview is that the instrumentalization of the nonhuman world is questioned to a larger extent. I conclude that, because the underlying concerns of those who held the “GM is unnatural” view were not with GM as such, yet with a worldview that was considered to be problematic, and of which many GM applications were held to be expressions, policy-makers and their advisors should reflect on the critical worldview of those who claim that GM is unnatural if they want to engage seriously with their concerns.  相似文献

Economic instruments, such as effluent fees and tradable discharge permits (TDP), have often been suggested by economists as efficient or cost-effective means to control pollution. In recent years such instruments have received increasing attention due to their growing political acceptability. Still, their use in practice has been tentative. The interest in possible application of such instruments has led to a set of studies regarding their practical potential. These studies indicate that economic instruments require substantial government involvement, entailing high administration cost; require restrictions so as to prevent significant deterioration in receptor areas; and have ambivalent effects on innovation adoption. Consequently, the efficiency gains from such instruments may be smaller than potential gains identified in earlier studies. In addition, the distributional impacts of such instruments and their possible adverse effect on market contestability reduce their attractiveness in some cases. These findings raise the question: what is the desired role of economic instruments in addressing environmental concerns? In recent years the demand for environmental services has increased dramatically. Current legislation and studies indicate that desired environmental expenditures are likely to increase. At the same time environmental programs face increasing competition from other programs for a declining pool of general revenues. One outcome of these processes has been the search for alternative sources of funds for environmental programs. Furthermore, as the competition for general revenue funds increases, the allocation of such funds for environmental programs becomes less predictable. This may endanger many long-term environmental programs that require stable funding. This article suggests that economic instruments may prove one source of dedicated funds for many environmental goals. Consequently, studies of environmental-program financing as well as studies of economic instruments may well explore the possible role of economic instruments as financing tools. Some examples of the potential of such tools for estuary cleanup programs are discussed.  相似文献

Summary The position and weaknesses of the Belgian environmental movement are assessed within their historical context. Recent intentions pronounced by prominent members of the movement are put into the context of the on-going constitutional and administrative reformation in Belgium. An analysis is made of the organizational and operational problems that exist within any planning process, including environmental planning processes. The problems in the latter type of process are severe due to the derived or indirect nature of the subject matter of environmental management and planning. It is argued that an appropriate response to the unique opportunities furnished by the administrative reorganization consists of demanding the establishment of a central planning and strategic control authority. This authority would be the initiator of the general planning processes within the Flemish Community. It would act on the indication of the Executive Cabinet and it would be charged with planning, programming, budgeting, and strategic control of goals and policy guidelines adopted by the Flemish Community Council. The role of environmental managers and planners will be twofold. They would be members of the planning teams within the central planning and strategic control authority, thus they would ensure the environmental soundness of planning. Secondly, they will be the implementators of specific planning actions, undertaken solely to enhance the quality of Flanders' battered environment. To execute the latter function, they will constitute the personnel of peripheral, implementation-geared, environmental agencies. Walter E. J. Tips holds degrees in general biology, ecology and town and regional planning from the State University of Ghent (Belgium). He has published in fields as varied as conservation, animal ecology, environmental planning and environmental impact assessment, and rural development planning. He has been a lecturer in planning in Malaysia and an advisor to Belgian landscape planning authorities. At present his main interest is in research on the possibilities of organizational reform of government administration to include environmental planning procedures in decision making and planning.  相似文献

Do individuals’ perceptions of their interdependence with the natural environment affect their environmental behaviors? From the perspective of interdependence theory, we introduce a scale to measure commitment to the natural environment. In Study 1, higher levels of commitment to the environment and greater inclusion of nature in the self separately predicted higher levels of pro-environmental behavior, even when controlling for social desirability and ecological worldview. In Study 2, participants primed to experience high commitment to the environment reported greater levels of pro-environmental behavioral intentions as well as pro-environmental behavior relative to participants primed to experience low commitment to the environment. Commitment to the natural environment is a new theoretical construct that predicts environmental behavior.  相似文献

The investigation is concerned with the reported incidence and frequency of homesickness following an environmental transition to university in a group of 101 first year university students. Definitions provided by students indicated that homesickness is a collective term for a number of cognitive and emotional/motivational experiences primarily associated with missing home and wanting to visit it. 60% reported homesickness. Geographical distance of the move and relative lack of satisfaction with features of the psychosocial and physical environment in the new place were found to be associated with homesickness reporting. Personality and circumstantial factors such as decisional control over the move and cognitive failure levels were also associated with homesickness reporting. A two-stage risk model is proposed in which an environmental relocation is a necessary but not a sufficient condition for homesickness; features of the new place combine with personality factors to precipitate the experience.  相似文献

There is a considerable debate on the effects of environmental regulation on competitive performance. Based on survey data, this paper analyzesthe two main research questions, derived from literature, on the links between environmental regulation and competitiveness, by focusing on firms operating in the building and construction sector, i.e.: 1) whether environmental policy stringency affects the competitive performance of firms in the building and construction sector 2) and how a specific form of environmental regulation (direct regulation, economic instruments and soft instruments) affects this performance? By applying a regression analysis, we find that a more stringent environmental regulation, measured by inspection frequency, provides a positive impulse for increasing investments in advanced technological equipment and innovative products and on business performance. Moreover, a well-designed “direct regulation” appears to be the most effective policy instrument for prompting the positive impact of environmental policies on innovation and intangible performance while economic instruments do negatively affect business performance.  相似文献

The scale and intensity of bushfire activity in Australia is likely to increase as a result of climate change. Effective bushfire management policy measures are therefore essential to minimise the interrelated social, environmental and economic impacts of fire in the landscape. This paper presents a historical review of bushfire management in the South West of Australia (SW): a bushfire prone and biodiverse region. Using a worldview framework to analyse key policy documents and literature, the paper demonstrates that the evolution of complex policy sectors such as bushfire management, is influenced not only by scientific and technical developments but also as a result of changing worldviews. Adapting the Integrative Worldview Framework (IWF), seven worldview categories that dominated particular periods of history in Australia are presented. These worldview categories are then used to examine the evolution of bushfire management practice, policy and institutional arrangements relevant to the SW. The argument presented herein is that a better understanding of worldviews and how they influence complex and contentious policy fields such as bushfire management, is useful for policy analysis, reflexive practice and research. The paper suggests an integrative worldview approach, which enables opportunities for exchanges and constructive conflict between stakeholders and agencies with diverse worldviews, could contribute to creating more sustainable bushfire management. Finally, it is argued that opportunities for Indigenous and Western worldview exchanges in the bushfire management sector, through collaborative knowledge partnerships could assist the sector in both management practice and policy formulation.  相似文献

The burgeoning literature on sustainable transitions links persistent environmental problems to the functioning of socio-technical systems. Conventional policy instruments, such as environmental taxation, are often rejected by transition scholars but in-depth studies on their potential are scarce. This paper explores the potential of the instrument of environmental taxation for influencing sustainability transitions. The multi-level perspective and the multi-phase perspective from transition thinking and the social practices approach are combined with the environmental economics theories of Pigou and Coase. Our analysis shows that the highest impact of regulatory taxation will be realised at the end of the take-off phase and in the acceleration phase of a transition. Although important barriers exist and many conditions apply, regulatory environmental taxation, especially as part of a smart policy mix, has more potential for contributing to sustainability transitions than hitherto assumed.  相似文献

Environmental accounts bring together economic and environmental information in a common framework to measure the contribution of the environment to the economy and the impact of the economy on the environment. They enable governments to set priorities, monitor economic policies more precisely, enact more effective environmental regulations and resource management strategies, and design more efficient market instruments for environmental policies. This article uses examples from the regional environmental accounting programme in southern Africa to demonstrate the usefulness of environmental accounts to policy-making and natural resource management. The examples address the contribution of natural capital endowments (minerals and fisheries) to sustainable development in Botswana and Namibia; the economic importance of non-market forest goods and services in South Africa; and the socio-economic impact of current water allocation and pricing policies in Botswana, Namibia and South Africa. While there are many additional policy applications, these few provide a powerful argument for the use of environmental accounts in all countries.  相似文献

Abstract

In recent years there has been increasing interest in the use of so‐called ‘economic instruments’ in environmental policy. Economic instruments influence the behaviour of economic agents by providing financial incentives for environmentally improved behaviour, or disincentives for damaging behaviour. This paper explores the use of economic instruments in the field of sustainable community planning and development. It does so in the wider context of how environmental economic policy is made. The focus of this paper is to examine the role of policy instruments in community planning, and to review the different types of instruments that are available to policy‐makers. Numerous examples of the various instruments at the community level are described. It is widely believed that policy making should occur at the lowest or most local level possible while maintaining effectiveness. A system of government that does not give adequate legal power to local governments, and does not allow local governments considerable flexibility in the use of funds, cannot be expected to achieve all community objectives. Central governments must give local governments permission to take measures towards sustainable community planning, even though that requires giving them power to address broader issues. At the same time, when issues that should be addressed at national and international levels are not addressed, local governments may be able to take action individually. Given the general reluctance (and perhaps inability) of governments at all levels today to consider non‐economic and, particularly, non‐market policy instruments, it is pragmatic as well as timely to improve our understanding of economic instruments for sustainable community development.  相似文献

This paper focuses on impediments to environmentally sound management practices and how these might be overcome, with an emphasis on the role of environmental management systems, supply chains and civil society. It argues that: Farmers are under increased pressure to cut costs and improve production but with little opportunity to increase prices. Commonly short-term economic interest has damaging environmental implications. Current government policy, in Australia and in many other jurisdictions, relies heavily on voluntary arrangements, education and information, as the main policy instruments through which to persuade farmers to adopt better environmental farm management - e.g. the recent push to encourage the use of voluntary environmental management systems. However, there is good evidence to suggest that these can only make a valuable contribution when combined with a range of other policy instruments, including positive and negative incentives, intervention by third parties and in some cases, an underpinning of regulation. Arguably, what is needed is a strategy that builds on the strengths of voluntary environmental management arrangements while compensating for their weaknesses by combining them with other, complementary policy instruments. If so, we must engage with a range of questions that have not so far figured substantially in the policy debate. Although the principal focus has been on the role of government in bringing about on-farm change in management practices, supply chain pressure (at least in respect of agricultural chemicals and practices which threaten food safety) and civil society action are also potentially powerful mechanisms for bringing about change. Government can and should play a role in harnessing such forces in the interests of improved environmental on-farm practices.  相似文献

This study examines managerial preferences for various policy mechanisms commonly used to address environmental problems using a sample of 653 Chinese managers from firms in Beijing, Dalian and Guangzhou. Overall, these managers appeared to favor regulatory instruments, placing somewhat less faith in market and communicative instruments. However, all measures appear to have ample support within each subgroup. In addition, the influence of two situational factors on these preferences was investigated--the immediacy of environmental impact and diffusion of responsibility. The results of the study indicate that these two factors interact in explaining managerial preferences, but only for the use of market mechanisms.  相似文献

This study compared the person and national-level personality correlates of environmental engagement. Associations between specific personality traits and environmental concern have been observed in a number of studies, but few have examined associations between the Big Five personality traits and environmental engagement. Associations at the individual-level were examined with the environmental value ‘protecting the environment’ (Study 1) and retrospective self-reports of electricity conservation behaviour (Study 2) in national probability samples. Country-level indices of sustainability, environmental attitudes, and harmony values were related to aggregate personality traits with data across nations (Study 3). Across both persons and nations, Agreeableness, Conscientiousness and Openness to Experience were the traits most strongly linked to environmental engagement. These findings provide insight into the ways in which stable regularities in overall behavioural patterns are linked to more specific aspects of conservation behaviour and attitudes both in persons and across entire societies. Theoretical explanations for the findings are proposed.  相似文献

People spend most of their time indoors, where air pollution levels rival and often exceed those outdoors for a number of important pollutants. Yet, little is known about people’s knowledge of indoor environmental hazards. The purpose of the current study was to construct a measure of indoor environmental knowledge. A set of 78 true/false items were developed with input from a panel of experts. The set of items was truncated with traditional item analyses, resulting in a reliable set of 21 items (α = .79). Concurrent validity was established by a significant correlation between the indoor environmental knowledge (IEK) scale and an established measure of science literacy (r = 0.44, p < .001). Schema theory guided the assumption that the two measures should be related. Convergent validity was established by the significant regression of science literacy, formal education in science and math, and status as an engineering student on IEK scale score, accounting for 25% of the variance in the IEK scale score. Future research avenues are proposed and limitations are discussed.  相似文献

We examined the connection between individuals’ relationships with the natural environment and their environmental behaviors with a focus on commitment to the environment, defined as psychological attachment and long-term orientation to the natural world. Commitment is theorized to emerge from structural interdependence with the environment and to lead to pro-environmental behaviors. Close relationships research has identified three key antecedents to commitment (satisfaction, alternatives, and investments). We developed environment-specific measures of these constructs, and factor analysis verified three distinct factors. A path analysis revealed that satisfaction with the environment and investments in the environment, but not alternatives to the environment, predicted commitment to the environment. Moreover, commitment mediated the effects of satisfaction and investments on general ecological behavior and willingness to sacrifice for the environment. In regression analyses, commitment predicted general ecological behavior and willingness to sacrifice for the environment, even when controlling for ecological worldview, inclusion of nature in the self, connectedness to nature, and environmental identity. Individuals who are satisfied with and invested in the natural world are likely to be committed to the environment and act with the well-being of the environment in mind.  相似文献

US government actions undertaken in Antarctica are subject to the requirements of both the Protocol and the US National Environmental Policy Act (NEPA). There are differences in the scope and intent of the Protocol and NEPA; however, both require environmental impact assessment (EIA) as part of the planning process for proposed actions that have the potential for environmental impacts. In this paper we describe the two instruments and highlight key similarities and differences with particular attention to EIA. Through this comparison of the EIA requirements of NEPA and the Protocol, we show how the requirements of each can be used in concert to provide enhanced environmental protection for the antarctic environment. NEPA applies only to actions of the US government; therefore, because NEPA includes certain desirable attributes that have been refined and clarified through numerous court cases, and because the Protocol is just entering implementation internationally, some recommendations are made for strengthening the procedural requirements of the Protocol for activities undertaken by all Parties in Antarctica. The Protocol gives clear and strong guidance for protection of specific, valued antarctic environmental resources including intrinsic wilderness and aesthetic values, and the value of Antarctica as an area for scientific research. That guidance requires a higher standard of environmental protection for Antarctica than is required in other parts of the world. This paper shows that taken together NEPA and the Protocol call for closer examination of proposed actions and a more rigorous consideration of environmental impacts than either would alone. Three areas are identified where the EIA provisions of the Protocol could be strengthened to improve its effectiveness. First, the thresholds defined by the Protocol need to be clarified. Specifically, the meanings of the terms “minor” and “transitory” are not clear in the context of the Protocol. The use of “or” in the phrase “minor or transitory” further confuses the meaning. Second, cumulative impact assessment is called for by the Protocol but is not defined. A clear definition could reduce the chance that cumulative impacts would be given inadequate consideration. Finally, the public has limited opportunities to comment on or influence the preparation of initial or comprehensive environmental evaluations. Experience has shown that public input to environmental documents has a considerable influence on agency decision making and the quality of EIA that agencies perform.  相似文献
