Abstract People generally do not perceive New England to be tornado-prone. Yet, there is a long history of such storms in the six states going back to the late seventeenth century. Usually, New England tornadoes are small and short-lived; even so, some have caused many deaths and much property damage. There is a greater probability for a person to be affected by a tornado in southern New England than in much of the American Midwest. As building and population density increases, so does the hazard potential. Data from awareness surveys indicate that the lack of tornado knowledge remains a serious problem for teachers, students, and the public, and government information about such storms is not being widely disseminated. 相似文献
Abstract Geography teacher preparation is an ongoing problem for the discipline. Changes in certification requirements and federal and state educational policies have diminished the role of colleges and universities in educating teachers. At the same time, geography education reform efforts have resulted in higher standards and an increased quantity of geography in the curriculum, pre-service programs have failed to produce an adequate supply of highly qualified geography teachers. This paper suggests that geographers implement geography mentoring programs to improve the quality of geography instruction in early-career teachers. A model developed for the National Geographic Society is described. The model uses Teacher Consultants as mentors to assist novice teachers at the stage in their development when they are most ready to improve practice: between years two and five of their career. 相似文献
The geology of New South Wales is diverse, spanning Paleoproterozoic to modern materials and their various associated landforms and soils. In recognition of the intrinsic geological value of the State, around 150 geological sites were nominated to the now defunct Register of the National Estate, with the objective of geoconservation. However, these sites did not encompass the full range of geology of New South Wales; neither did they offer registered sites any protection. Analysis shows that the types of sites nominated were biased towards sedimentary and igneous rocks, and fossils, with under representation of metamorphic rocks, site-restricted soils, geomorphology and hydrogeology. To test the utility of the Brocx and Semeniuk ‘Geoheritage Toolkit’, a subset of the Register listings was re-examined, focusing on the Sydney Basin. Within the Sydney Basin, 59 nominated sites were reassessed using various geoheritage categories and the hierarchical framework of scale of the Toolkit. Four sites within the Sydney Basin were found to have features of international to national significance, and to have national historical value. These sites will need to be renominated for State and National listing. Clearly, to ensure that University teaching sites, as well as stratigraphic and lithologic type sections and reference sites, reflecting the geodiversity of New South Wales are conserved for future generations, a greater number of sites need to be put forward for heritage listing. 相似文献
ABSTRACTThe Australian government’s proposal to expand the Snowy Hydro Scheme to include a second pumped hydro energy storage (PHES) system, and support for feasibility studies for PHES in Tasmania, offer an opportunity to incorporate more intermittent renewable energy generation into the National Energy Market. However, the infrastructure construction required for PHES expansion may have negative effects for biodiversity in subalpine and alpine areas. To identify the potential effects of PHES on biodiversity in Kosciuszko National Park (KNP), this systematic literature review assesses: (i) the key environmental disturbances likely to arise from PHES construction; and (ii) the specific impacts of these construction processes on biodiversity in subalpine and alpine environments. We find that the effects of PHES construction-related disturbances are likely to be negative for subalpine and alpine biodiversity, with impacts including the proliferation of exotic flora, habitat loss resulting from vegetation clearing, altered landscape hydrology and reduced water quality. Management recommendations to limit these impacts are provided and further research is recommended to assess: (i) the effects of PHES on fish populations in alpine reservoirs; (ii) the utility of spoil as artificial habitat for endemic fauna; and (iii) the chemical and physical impacts of spoil dumping in alpine reservoirs. 相似文献
This paper analyzes the role of the National Natural Science Foundation of China (NSFC) in advancing human geography in China by focusing on five key research areas: land use, urban systems and urban agglomeration, economic globalization, climate change and social and cultural geographies. All NSFC-funded human geography programs related to these five topics from 1986 to 2017 comprise the sample for analysis, and the research topics, content, teams, and peer-reviewed journal publications supported by these programs are investigated. Specifically, this paper analyzes the NSFC’s promotion of the expansion of research topics in response to national developmental needs and the shifting frontiers of human geography research internationally, its enhancement of interdisciplinary research, and its contributions to the assembly of specialized research teams. The paper also reports important progress in Chinese human geography over the past 30 years through the institutional lens of the NSFC, revealing major characteristics and trends in the discipline. The paper concludes by calling for further collaboration between the research community and the NSFC for the development of a locally suitable and globally influential Chinese human geography. 相似文献
This article provides insights into the role of institutions involved in climate governance working towards a future low-carbon society at the national level, within the global climate change governance architecture. Specifically, it contributes to understanding the fragmented governance of energy efficiency policy in developing countries by focussing on Vietnam’s building sector, identifying key institutions related to underlying discourses, national and international power relations, resource distribution and coalitions. It uses the case of baseline setting in developing Nationally Appropriate Mitigation Actions (NAMAs) to illustrate institutional dynamics, nationally and transnationally, as well as to question whether demands for baseline setting achieve the ideal trade-off between actual GHG emissions reduction and institutionalized demands for accountability. The analysis reveals that, in addition to domestic efforts and challenges, the international agenda greatly influences the energy efficiency policy arena. The article presents lessons to be learnt about policy processes from the specific Vietnamese case, reflecting on the role of international actors and discourses in it. Finally, it argues for the abolition of baselines in favour of adequate monitoring and evaluation, from the perspective that requirement for deviation from fictitious baselines is unproductive and only serves an international techno-managerial discourse.
POLICY RELEVANCE
Baseline establishment is commonly considered an initial step in developing NAMAs, in order to facilitate the demonstration of a deviation from such baselines. The requirement to produce baselines is traditionally not questioned by policy practitioners. Thus, significant development resources are allocated to the establishment of baselines and the bridging of data gaps, often without consideration as to whether baselines are a necessary instrument for NAMA implementation. We suggest omitting the lengthy and resource-consuming practice of establishing baselines and recommend proceeding forthwith to the planning and implementation of mitigation and energy efficiency policies. As conditions vary significantly in different contexts, it would be more appropriate to measure the initial situation, establishing the ‘base point’, and monitor development from that point. The present article might serve as motivation for policymakers to question traditional approaches to policy development and consider alternatives to maximize the cost efficacy of NAMA programmes and facilitate their implementation. 相似文献
