鉴于湿地生态系统的特殊性和敏感性,科学地保护和利用湿地资源、合理地进行湿地利用规划,一直是相关学者所关注的问题;以安徽省北部淮河三汊河湿地为例,从水文调节、大气调节、水体净化、物质生产、文化功能、提供生境和生物多样性价值等方面采用替代成本法、恢复成本法、市场价格法和影子工程法对湿地生态服务价值进行经济核算;分别以生态服务功能价值的理论值(2152.9万元)和现状值(1982.7万元)为参考标准,进行湿地公园规划对湿地生态影响的比较分析,预评价湿地公园规划后的生态服务功能价值为2447.2万元,较理论值和现状值都高;在各项服务功能中,除物质生产功能影响为负值外,其它各项值均为正值,在水文调节、水体净化和文化功能方面变化值较大,因而,从生态服务功能角度考虑,可以认为公园规划具备合理性和可行性。 相似文献

This article reports on one outcome from a three-year study with pre-service primary teachers at Goldsmiths' College, University
of London. The purpose of the study was to evaluate the influence of participants' prior educational experience and beliefs
about the relationship between design & technology (D&T) and science on their lesson planning for these subjects during school
placements. Data from the study support a three-domain model of pre-service teachers' thinking and action. When operating
within the pragmatic domain, participants are primarily concerned with survival in the classroom, resulting in short-term planning which may contradict
their epistemological and curricular beliefs. In the pedagogical domain, the focus shifts from the pre-service teacher themselves and their immediate survival to the learning potential of
the activities they plan. There is evidence that some participants have progressed to operating within a philosophical domain, leading to clasroom practice which reflects and re-conceptualises pre-service teachers' core beliefs about the nature
of, and relationship between, D&T and science.

Tourism is frequently cited as a tool by which American Indians can strengthen the economies of their reservations. However, successful tourism development on such reservations requires effective tourism planning, and effective tourism planning requires public participation in the planning process. The Nominal Group Technique (NGT) has proved to be a useful group process in the tourism field but its application to tourism planning on American Indian reservations has been unexplored. This article helps to fill this knowledge gap by reporting on an NGT workshop conducted on the Lake Traverse Reservation of the Sisseton–Wahpeton Oyate (people, nation) in North and South Dakota, USA. Rich information on tourism development possibilities for three lakefront properties was obtained. Possible success factors are discussed and suggestions for conducting similar future workshops on American Indian reservations are advanced. 相似文献

Neuman, Yoram, Abraham Pizam and Arie Reichel, Values as Determinants of Motivation: Tourism and Other Career Choices. Annals of Tourism Research 1980, VII (3): 428–442. This study examined the predictive validity of work values in explaining motivational patterns of three groups of career preparation differing in their occupational specificity: Tourism/Hospitality, Management, and Liberal Arts. It was found that the higher the occupational specificity of a career preparation the higher is the predictive validity of work values in explaining work motivations. As predicted, the best relationships between values and motivation was found in the maximally specified occupation, namely: tourism/hospitality students, followed by management students with the liberal arts students — the most flexible occupational group — having the lowest relationship between values and motivation. The implications of the findings for employee selection and motivation prediction in the tourism/hospitality industry are discussed. 相似文献

The complex rapidly changing environment faced by tourism organization officials makes tourism planning extremely difficult. Goal programming can aid the tourism planner in appraising the goal attainment potential associated with proposed tourism marketing program alternatives. By changing priorities of goals, budgetary limitations, and organizational constraints, the policy maker can test the effect of changes before they are implemented. By utilizing goal programming, a tourism organization can more systematically evaluate the nature and relative importance of organizational goals, critical constraints affecting the organization and marketing program alternatives. 相似文献

Scenario planning in the public sector has significant differences from scenario planning in the corporate world. Scenario planning in the government not only tends to be focused on issues of higher complexity and significance to public policy, but also in comparison to people in the private business, public officials have fundamental psychological and institutional constraints in their scenario thinking. These constraints make it difficult for them to contemplate multiple ‘untidy’ futures and imagine the possibility of policy failure: skills which are essential for successful scenario projects. Based on specific characteristics of scenario planning in the Japanese government, this paper contributes on better understanding the challenges and strategic solutions in providing more successful scenario planning in the public sector. Specifically, this paper argues that possible solutions in overcoming these constraints may be to shake public bureaucrats out of their thinking by providing free and open venues of conversation and more importantly through ‘derailment’ exercises. 相似文献

This study investigates the performance of analysts when they match the asymmetric timeliness of their earnings forecast revisions (i.e., asymmetric forecast timeliness) with the asymmetric timeliness of firms’ reported earnings (i.e., asymmetric earnings timeliness). We find that better timeliness‐matching analysts produce more accurate earnings forecasts and elicit stronger market reactions to their forecast revisions. Further, better timeliness‐matching analysts issue less biased earnings forecasts, more profitable stock recommendations and have more favorable career outcomes. Overall, our results indicate that analysts’ ability to incorporate conditional conservatism into their earnings forecasts is an important reflection of analyst expertise and professional success. 相似文献
