While the links between contaminated sites and adverse effects on human health and well‐being are being increasingly recognised, some argue that the magnitude of the health problem is inadequately addressed because it is largely invisible. Health geographies literature has sought to highlight this invisibility by focusing on the link between contaminated sites and health. This study adds to health geographies by presenting unique insights into the geography of residents' worry about the disruptive effect of environmental contamination on health and well‐being. It analyses a sample of residents (n = 485) living near 13 contaminated sites across Australia. Ordinal logistic regression analysis of closed‐format survey questions was combined with coding of open‐ended survey questions to reveal the geography of residents' worry about contamination from nearby sites. First, the study explores some of the main relationships between residents, their environs, and contaminants from nearby source sites, which determines their levels of worry: residents' demographics, residents' proximity to sites, contaminant boundaries and borders, and type of contaminant. Second, the study investigates how worry affects residents' health and well‐being, ranging from effects on their personal functioning through to their sense of ontological security, which depends in part upon their perceptions of contaminants' impacts. Despite having identified a range of diverse and negative effects of worry about contamination on residents, we found that worry for contamination can also prompt coping strategies and problem‐solving, reinforcing the need for more research on this subject.  相似文献

It is proposed that there is an iconographic and epistemological relationship between some drawings in Felipe Guaman Poma de Ayala’s Nueva corónica y buen gobierno and the images recorded in several colonial wood vessels (qeros) which circulated widely during the time that Guaman Poma was writing his letter to the King of Spain. This connection shows that the work of Guaman Poma was not an isolated or singular act in the colonial context and that both communicative and creative processes, that of the Nueva corónica and that of the qeros, formed part of a process of shared colonial semiosis through which Andean societies maintained a certain autonomy in the production and circulation of their own discourses. Secondly, the article discusses the epistemological tension that results from the coexistence of different narratives (European and Andean) that used their own temporal and spatial categories to account for new colonial conditions.  相似文献

This study seeks to advance the understanding of the utility of “soft power” by exploring the case of Qatar. The country's approach is conceptualized as “nested power” through the examination of its political strategies before and after the regional blockade in 2017. The role of soft and nested power in Qatar has already been examined through various vantage points, such as small state diplomacy, mediation, and sports. Since the blockade has been for Qatar a great strategic dilemma, examination of how it affected power dynamics reveals the salience as well as the resilience of Qatar's soft and nested power. The article will discuss the concepts of “soft” and “nested” powers and their relevance to the state of Qatar in general and it will focus in the final section on the post‐blockade period. In doing so, we also seek useful approaches, which can be compatible with, and even advance “global international relations” (IR). The movement to make IR more global and inclusive is a welcome feature of the current century, reflective of the burgeoning role of the “Global South.”  相似文献

Throughout the 1960s, Spanish students staged a strong opposition against the dictatorship of General Franco. Also during this decade, the U.S. Foreign Service in Spain began to pay great attention to these students for two key reasons. On the one hand, student protests posed a threat to US defensive interests in a country with a high strategic value during the Cold War in southern Europe. However, on the other hand, campus agitation could lead to positive effects for the United States if students’ expectations of social change were channeled toward national development in a context of order and political stability. So, how could student activism and idealism be directed toward a controlled modernization of Spain? This article attempts to answer this question by studying American programs aimed at disseminating the principles of modernization theory in Spanish universities as an instrument to (1) influence students’ political and intellectual socialization and to immunize them against radical ideologies and (2) channel students’ aspirations towards constructive and responsible reform of their country's socioeconomic structures.  相似文献

In 2010–11 a pedestrian survey of the western end of Wadi al‐Hijr in northern Oman identified 1507 archaeological features in a 124 km2 area. Data were collected on each feature's architectural characteristics, associated artefact assemblages, topographic and environmental locations, condition of remains, and relations to other archaeological features. The majority of datable features belong to the third millennium BC and divide unequally between the Hafit and Umm an‐Nar periods. While the majority of these third‐millennium BC features were tombs, other feature types were identified, including towers, settlements, quarries, dams, enclosures, and possible platforms. Third‐millennium BC features were organised into clusters and ranged considerably in size, from a few features to several hundred. All of the clusters established during the Hafit period were maintained in the Umm an‐Nar period, suggesting a continuity throughout the third millennium. Some preliminary hypotheses regarding settlement patterns are suggested.  相似文献
