The concept of providing a fuse in a structural system has been both developed and investigated over the past few years (e.g., the use of replaceable links in eccentrically braced frames or the use of replaceable links in the new San Francisco-Oakland Bay Bridge). This paper presents a new coupling beam with a creative fuse installed in the mid-span of a steel-concrete composite beam via an end plate and high-strength bolts. First, a practical design methodology of a replaceable coupling beam is presented. Next, the seismic behavior of the proposed fuse is tested and evaluated, and two structural wall specimens with or without a fuse are designed and fabricated according to the proposed design methods. The two specimens possess similar shear capacities under large-scale cyclic loading, and the walls of the two specimens show similar failure modes; however, the new walls exhibit slightly lower levels of damage than the conventional walls. In particular, the inelastic deformation and damage of replaceable coupling beams are mainly concentrated in the fuse, whereas the non-yield segment and the beam-wall pier interfaces remain nearly intact and produce only slight damage, which is beneficial regarding the replacement of the fuse in post-earthquake events.  相似文献

With the onset of the Arab uprisings at the end of 2010 and the emergence of popular demonstrations that raised the issue of crises of legitimacy across the Arab states, the literature on democratization in the Middle East and North African (MENA) studies has taken on new dimensions recently. One of the primary theoretical debates that has surfaced in the post‐2011 era has revolved around on whether or not the demonstrations will lead to regime change or increased authoritarianism in the MENA region. One of the crucial developments of the Arab Spring has, then, been the overthrow of some long‐standing rulers like Ben Ali of Tunisia and Mubarak of Egypt, as well as the questioning of authoritarian regimes by the masses. The public protests submerged some Arab republics, but monarchies found ways to overcome the public outcry through containing the opposition. This paper, therefore, takes the monarchy of Morocco as a case study with the aim of analyzing the methods and regime‐survival strategies the regime has employed to sustain itself and consolidate power in the post‐2011 Arab uprisings era. Additionally, the role of the Justice and Development Party as an emerging threat in the postdemocratization era, and the changing nature of the party’s relations with the palace, will be addressed.  相似文献

For this study the narratives of 16 young women who had served as child soldiers with the Lord’s Resistance Army (LRA) in northern Uganda were collected. They had spent between 2 months and 16 years in captivity before managing to escape. All of them spent time at the Gulu Support the Children Organization Rehabilitation centre, from which 12 had moved back into their communities. The narratives start with their capture, the time with the LRA, the escape and the returning and reintegrating. Even though the narratives included appalling stories about the time in captivity, the participants expressed hope for the future and focused on giving their children a good start in life. We used Antonovsky’s theories about ‘sense of coherence’ coupled with resilience theory to discern the factors that helped these young women cope. The participants all managed to leave captivity. We have no comparative information about those who are still in captivity.  相似文献

Risk assessment is affected by large uncertainties, depending on hazard, structure, damage, and loss analysis. Crucial problems and choices may refer to: (a) hazard parameters, including the definition of appropriate ground motion levels and of their probability to occur; (b) level of knowledge about materials, geometry, detailing; (c) assessed damage and failure modes; and (d) resulting potential for step changes in performances.

The cost of attaining a high level of knowledge may significantly reduce the remaining resources, it is therefore important to favor resilient solutions with a creative adoption of appropriate strengthening strategies.

In this framework, this article discusses the possible criteria for the mitigation of seismic risk and some of the alternative choices that may be adopted for strengthening, with reference to:

(a)?the modification of damage and collapse modes strengthening individual elements or locallyincreasing the deformation capacity;

(b)?the insertion of additional systems resisting to horizontal actions;

(c)?the introduction of base isolation, with the objective of capacity-protecting the existingstructure;

(d)?the reduction of displacement demand by added damping or introducing tuned masssystems.

Alternative strengthening choices lead to different protection levels and imply different performances that are, in general, represented by non linear or step functions of a cost parameter of the intervention. From these considerations, conceptual “structure driven” strengthening criteria, based on a logical use of resources, are discussed.  相似文献

ABSTRACT

Tourism is a well-known way of life for an increasing portion of the world's indigenous communities, and it has taken tortuous paths and undergone changes in approach and meaning.

Indigenous tourism is examined here within the theoretical framework of resilience, focusing on development, communication and justification. Men and women and their perspectives on space, time and spatial relations are the crucial agents in these processes. Based on an empirical study in Québec, Canada, we show that the impact of indigenous tourism includes networks within the local community at the regional and national levels, as well as translocal networks and relationships. Communicative processes are essential for achieving resilience, communicating identity within families and the community, and giving a voice to a political project. We argue that indigenous tourism works on several geographical levels and that these levels intersect and have the potential to increase resilience if they interact. Our study supplements resilience development theory by highlighting the need to consider communities as parts of networks. It also contributes to the field of tourism research by emphasising communication on several levels.  相似文献

In this article, Grove and Adey's (2015) call to capture the multiplicities of resilience through aesthetics is advanced by engaging with the first two seasons of the television series Breaking Bad. This engagement demonstrates that the relationality of geopolitics and mobility is important for resilience. To capture dynamics generated by the interplay of geopolitical contexts and resilient subjectivities through popular geopolitics, Jacques Rancière's aesthetics and the concept of the aesthetic subject are deployed. The emergence of homo resilio as a political subject within an imagined American heartland is presented to contextualise the aesthetic reading of Breaking Bad that follows. The character Walter White is presented as a paradigmatic example of homo resilio to map the geopolitics of this subject position. The paper concludes that race and gender feature at the intersections of homo resilio, geopolitics, and cultural criticism, reiterating the importance of popular geopolitics for capturing the multiplicities of resilience.  相似文献

This essay uses the case of Hurricane Maria in Puerto Rico to discuss “the coloniality of disaster”: how catastrophic events like hurricanes, earthquakes, but also other forms political and economic crisis deepen the fault lines of long-existing racial and colonial histories. It argues that disaster capitalism needs to be understood as a form of racio-colonial capitalism and that this in turn requires us to question our understandings of both “resilience” and “recovery.” The article focuses on the “wait of disaster” as a temporal logic of state subjugation and on how Puerto Ricans responded to state abandonment through modes of autogestión, or autonomous organizing. It concludes that while resiliency can be coopted in service of a neoliberal recovery, it can also be the site for gestating new forms of sovereignty and new visions of postcolonial recovery.  相似文献

Sustainability has been a core conceptual framework for community development since the approach was popularized in 1987, although in its essence it reflects a long history of environmental conservation reactions to industrialization. Resilience, as a framework for understanding and approaching community development, emerged more gradually out of ecological studies in the 1980s, but has only recently, since the mid-2000s, emerged as a focus of public interest as a way of responding and adapting to the planet's growing anthropogenic changes. For many, sustainability and resilience are slightly nuanced perspectives on the same phenomenon. For others, however, there are distinct differences between them, with sustainability's conservation goals being in opposition to the adaptation goals of resilience. Two major reasons for these confusions are (1) both concepts are defined and used in many different ways to achieve a variety of political goals that may not reflect their core definitions, and (2) both concepts share similar goals and some common approaches, such as a focus on climate change and seeking a balance between humans and nature. Returning to the core definitions of conservation and adaptation helps to clarify their similarities and differences, as well as to articulate indicators for understanding how each applies to community tourism development. Indicators from research in rural Taiwan tourism communities were therefore based on responses to the questions: What does the community want to conserve and how do they want to do it (sustainability)? What do they want to change and how do they want to do it (resilience)? Preliminary results suggest that the new ideal community is the one that is both sustainable and resilient.  相似文献

Hospitals are critical infrastructures which are vulnerable to natural disasters, such as earthquakes, man-made disasters and mass causalities events. During the emergency, the hospital might also incur in structural and non-structural damage, have limited communication and resources, so they might not be able to treat the large number of incoming patients. For this reason, the majority of medium- and large-size hospitals have an emergency plan that expands their services quickly beyond normal operating conditions to meet an increased demand for medical care, but it is impossible for them to test it before an emergency occurs. The objective of this article is to develop a simplified model that could describe the ability of the Hospital Emergency Department to provide service to all patients after a natural disaster or any other emergency. The waiting time is the main response parameter used to measure hospital resilience to disasters. The analytical model has been built using the following steps. First, a discrete event simulation model of the Emergency Department in a hospital located in Italy is developed taking into account the hospital resources, the emergency rooms, the circulation patterns and the patient codes. The results of the Monte Carlo simulations show that the waiting time for yellow codes, when the emergency plan is applied, are reduced by 96%, while for green codes by 75%. Then, using the results obtained from the simulations, a general metamodel has been developed, which provides the waiting times of patients as function of the seismic input and the number of the available emergency rooms. The proposed metamodel is general and it can be applied to any type of hospital.  相似文献

This paper argues that indigenous peoples' responses to climate change are better understood in relation to emerging notions of citizenship than to climate change crisis narratives. The latter, like development narratives, are often used to license the intervention of experts in debates about resource management and conservation. Dominant climate change narratives about the Arctic emphasise the power of global climate systems to threaten northern communities by situating them as being intrinsically ‘at risk’. These narratives envisage Arctic citizenship within very narrow parameters which have largely masked the voices of northern citizens. Definitions of ecosystem resilience, while providing a framework for comparing disparate cultural and ecological contexts, are predicated on avoiding systemic collapse. It is argued that such definitions heighten the sense of risk implicit in climate change impacts. This may ultimately impede the development of different aspects of civic participation by northern citizens with climate change policy opportunities. Policy responses across a range of diverse geographical contexts require new narratives that put communities back into the calculus of risk and decision-making. One way to be more critical about the language of climate change narratives is to evaluate the extent to which they can account for, and mitigate, growing inequalities of power and wealth. Studies in the historical reception of science narratives are proposed as a better approach for making grounded comparisons of the discursive strategies with which climate change narratives are made to work. This also helps to bridge discussions of climate change across regions like the Arctic and Africa, which share much in common, but are too often studied in isolation.  相似文献
