Environmental stewardship—a concept that describes the relationships between humans and the environment—is gaining increased attention as an approach that can address planetary sustainability issues. In-depth empirical investigations of local environmental stewardship are needed to understand how social-ecological context influences stewardship, as well as the arrangement of conceptual elements in applied settings. This study addresses these needs by conducting an in-depth exploration of environmental stewardship in the Niagara Region of Canada. A single embedded case study design is employed, with environmental stewardship initiatives constituting the individual units of analysis with the case. Analysis of the spatial arrangement of a total of 89 initiatives indicated that initiatives tended to cluster closer to the Niagara River and in more populous municipalities. The significance of collaboration, tensions between the environment and economic development, and concerns about political impacts emerged as themes across contextual factors. The configuration of stewardship elements reveals interesting discrepancies between initiatives and previous stewardship research focused on larger scales, individuals, and organizations. Further analysis is encouraged to illuminate environmental stewardship in other settings as well as advance relational understanding of conceptual elements.  相似文献

ABSTRACT

The highest number of German scholars and physicians, forced by the National Socialist regime to emigrate for “race” or political reasons, were from Berlin. Language and medical exams were requested differently in their new host country—the United States—leading to a concentration of immigrants in the New York and Boston areas. Very early Emergency Committees in Aid of German Scholars and Physicians were established. Undergraduate students (like F. A. Freyhan, H. Lehmann, and H.-L. Teuber) from Berlin seemed to integrate easily, in contrast to colleagues of more advanced age. Some of the former chiefs and senior assistants of Berlin’s neurological departments could achieve a successful resettlement (C. E. Benda, E. Haase, C. F. List, and F. Quadfasel) and some a minor degree of success (F. H. Lewy and K. Goldstein). A group of neuropsychiatrists from Bonhoeffer’s staff at the Berlin Charité Hospital could rely on the forceful intercession of their former chief. The impact of the émigré colleagues on North American neuroscience is traced in some cases. Apart from the influential field of psychoanalysis, a more diffuse infiltration of German and European neuropsychiatry may be assumed. The contribution to the postwar blossoming of neuropsychology by the émigré neuroscientists K. Goldstein, F. Quadfasel, and H.-L. Teuber is demonstrated in this article.  相似文献

Crown Prince Mohammed bin Salman is moving across the international stage as the future King of Saudi Arabia. He has the support of his father, Saudi royals, and the oil income of his country. He also has 10‐year plan he agreed upon with the King called Vision 2030. The three components of the Vision are to diversify the oil‐based economy to include technology and tourism, to make the country the heart of Islam and Arab culture and to become the economic and geographic hub of Asia/Europe and Africa. His rise in power will depend upon his skill in expanding the religious tolerance of Saudi people, the current economic structure of the country, and the education of the youth. He is simultaneously addressing all these challenges in order to cement the country's future sustainability. Suggestions for enhancing his multifaceted impact on his country are provided.  相似文献

Recent articles critical of the use of context in contextual intellectual history have identified contextual method with the post‐1960s work of the “Cambridge School,” which is regarded as being grounded in a flawed theory of textual interpretation. Focusing on German cultural and political history, this article shows that a contextual historiography was already fully developed in seventeenth‐century ecclesiastical history, and a parallel version of this approach had developed in the field of constitutional history. The modern critique of context emerged only with the appearance of dialectical philosophical history in the first decades of the nineteenth century. The article argues that rather than representing a scholarly engagement with contextual historiography, the central plank of the dialectical critique of contextualism—the notion that contextual explication of thought is insufficient because context itself has transcendental conditions—is actually a cultural‐political attack on it launched on behalf of a hostile and incommensurable academic culture.  相似文献

It is widely acknowledged in the literature that the study of blame avoidance behavior (BAB) exhibited by public officials is scattered and unconcentrated, and that, for the most part, it neglects both contextual factors and comparative research. These deficits inhibit the production of the kind of generalized findings necessary to better understand potential consequences for the policy process and the workings of political systems. We address these deficits by developing a framework that takes stock of blame avoidance research, clarifies the explanatory potential of contextual factors, and allows for a systematic context‐sensitive cross‐case analysis. For illustrative purposes, the framework is applied to the Home Insulation Program in Australia as a critical case. This case reveals the explanatory potential of contextual factors for the understanding of BAB and the consequences thereof. We conclude by stating the advantages of our framework and explain how it can be used for comparative research.  相似文献

From 1955 to 1988, the Royal Australian Air Force (RAAF) maintained a large airbase in Northern Malaysia. For the first 15 years of its existence, RAAF Butterworth had a modest and incomplete perimeter fence. With the end of British military colonialism in Malaysia and Singapore following the implementation of the ‘East of Suez’ policy, the Australians became preoccupied with their physical security and the role of the perimeter fence. By exploring the adoption of practices of exclusion via physical barriers in the wake of British withdrawal, this paper argues that the changing psychological outlook of Australian military officials reflected broader Australian anxieties about their own sense of ‘Britishness’ and the nation’s place in a decolonising Asia. As the Australians lost their British ‘blanket’ they built a fence.  相似文献

In Israel and Palestine, map-making practices were always entangled with contradictive spatial identities and imbalanced power resources. Although an Israeli narrative has largely dominated the ‘cartographic battlefield’, the latest chapter of this story has not been written yet: collaborative forms of web 2.0 cartographies have restructured power relations in mapping practices and challenged traditional monopolies on map and spatial data production. Thus, we can expect web 2.0 cartographies to be a ‘game changer’ for cartography in Palestine and Israel. In this paper, I review this assumption with the popular example of OpenStreetMap (OSM). Following a mixed methods approach, I comparatively analyze the genesis of OSM in Israel and Palestine. Although nationalist motives do not play a significant role on either side, it turns out that the project is dominated by Israeli and international mappers, whereas Palestinians have hardly contributed to OSM. As a result, social fragmentations and imbalances between Israel and Palestine are largely reproduced through OSM data. Discussing the low involvement of Palestinians, I argue that OSM's ground truth paradigm might be a watershed for participation. Presumably, the project's data are less meaningful in some local contexts than in others. Moreover, the seemingly apolitical approach to map only ‘facts on the ground’ reaffirms present spatio-social order and thus the power relations behind it. Within a Palestinian narrative, however, many aspects of the factual material space might appear not as neutral physical objects but as results of suppression, in which case, any ‘accurate’ spatial representation, such as OSM, becomes objectionable.  相似文献

Many questions remain about the effects of digital media use on citizens’ political engagement. This article argues that this is because such effects depend on the context in which digital media are used. Its findings are based on two cross-sectional sets from the 2010 and 2013 Australian Election Study and show that (1) political resources played different moderating roles in the association between digital media and offline participation, and (2) such a moderating role depended on different campaign contexts in the two elections, with context affecting political efficacy. The findings confirm that campaign context can function as leverage in motivating online news consumption and political participation, thereby emphasising the importance of political contexts in media use and political behaviour.  相似文献
