Between 2000 and 2014, more than thirty geography departments adopted revised or new names, with some entirely dropping geography. Although renaming and rebranding efforts are not new to higher education, the rapid pace at which geography department names have changed raises questions about the discipline's identity and health. We examine the renaming trend within geography programs together with intended and unexpected factors as perceived by faculty. Specifically, we look at the renaming and rebranding trend within the context of four pillars offered by Pattison (1964) to define geography's principal academic domains—earth-science, man–land, area/regional studies, and spatial traditions. 相似文献

Past research suggests that how we perceive risk can be related to how we attribute responsibility for risk-related issues, such as climate change; however, a gap in research lies in exploring possible connections between attribution of responsibility, risk perception, and information processing. Using the Risk Information Seeking and Processing model, this study fills this gap by examining how RISP-based variables are related to information processing and whether attribution of responsibility for mitigating climate change influences communication behaviors that are often predicted by elevated risk perceptions. Undergraduates at two large research universities (N = 572) were randomly assigned to read one of two newspaper articles that emphasized either individual responsibility (by highlighting personal actions) or societal responsibility (by highlighting government policy) for climate change mitigation. Results indicate that subjects in the individual responsibility condition were significantly more likely to process the message in a systematic manner; however, attribution of responsibility did not interact with risk perception to influence systematic processing. Moreover, attitudes toward climate change information and negative affect mediated the relationship between other key variables and systematic processing. These and other findings suggest that strategic communication about climate change may benefit from emphasizing individual responsibility to attract more attention from diverse audiences and to promote deeper thinking about the issue. Additional theoretical implications are presented. 相似文献

As the social, ecological and economic benefits of green buildings become more established, firms, especially professional service firms, are responding by adopting sustainable office space (SOS). Accelerating this uptake demands a nuanced appreciation of firms’ understandings of and motivations for adopting SOS. Through a qualitative study of professional service firms in Sydney, this paper brings together a decentred understanding of the contemporary firm drawn from the ‘new economic geographies’ approach and theories of corporate social responsibility to trace and interpret the diverse and overlapping motivations shaping the uptake of SOS amongst these firms. The firm is shown to be a site of plurality and agency, governed by multiple logics. Whilst motivations informed by economic logic remain persuasive and pervasive, the adoption of SOS is simultaneously informed by a wider palette of logics, including environmental and social logics. The paper argues that a decentred conceptualisation of the firm brings the multiplicity of firms’ orientations towards SOS into view and, in so doing, has the potential to inform a politics of intervention for steering firms towards more socially and environmentally sustainable behaviours. 相似文献

The scientific environmental ethics plays a key role in the recognition of the human- environment interactions. Modern environmental ethics is the philosophical re-thinking of modern human race environmental behavior. The development of environmental ethics theory, as well as its application in reality, determines the viewpoints of environmental ethics. Sustainable development implies harmony on human-environment interactions and inter- generation responsibility, with emphasis on a harmonious relationship among population, resources, environment and development, so as to lay a sustainable and healthy foundation of resources and environment for future generations. The harmonious society construction in China that is raised by the Chinese central government should be covered by environmental ethics. The connotation of open environmental ethics includes a respect for nature, care for the individual human race, and respect for the development of future generations, which means giving consideration to natural values, individual and human race benefits and welfare across generations. The role of environmental ethics in regional development consists of cognition, criticism, education, inspiration, adjusting, legislation and promoting environmental regulations. The major problems in regional development are extensive resource exploration, fast population growth, irrational industrial structure, unfair welfare distribution and the twofold effects of science and technology development. The formulation of environmental ethics that aims at regional sustainable development, can not only harmonize the relationship of population, resource, environment and economic development, but also guide behavior selection, push social and political system transformation, strengthen the legal system, and raise environmental awareness of the public. 相似文献

Conflicts between different interest groups for use of natural resources is one area where state geological surveys can provide
assistance. A state geological survey working within the scientific constraints of specific issues can remain objective in
its presentations and maintain the faith of both the conflicting interest groups and the public. One cannot vary from the
objective view or you will quickly be criticized. Criticism can still occur from one side of a natural resource issue as your
data might counter their views. However, the final decisions are almost always made in some legislators, or regulators, area
of responsibility. The responsibility of the state geological survey is to provide the important data that will assist in
making correct decisions. Should one party in the conflict become extreme in their demands, a potential compromise that is
beneficial to both sides can be lost. In Kansas, the classical natural resource problem of resource/recreation in a populated
area is presented as a case study. The state geological survey presented data on sand resources in the Kansas River and its
valley in northeast Kansas. That information was important to both recreation and dredging interests where the political problem
is a conflict of sand use as a construction material resource versus use of the alluvial river as an important recreation
area, especially for canoeing. However, when a reasonable compromise was near completion in the Kansas Legislature one side,
in a bold move to develop an advantage, ruined that potential for compromise.
