In this article, an agent‐based framework to quantify the seismic resilience of an electric power supply system (EPSS) and the community it serves is presented. Within the framework, the loss and restoration of the EPSS power generation and delivery capacity and of the power demand from the served community are used to assess the electric power deficit during the damage absorption and recovery processes. Damage to the components of the EPSS and of the community‐built environment is evaluated using the seismic fragility functions. The restoration of the community electric power demand is evaluated using the seismic recovery functions. However, the postearthquake EPSS recovery process is modeled using an agent‐based model with two agents, the EPSS Operator and the Community Administrator. The resilience of the EPSS–community system is quantified using direct, EPSS‐related, societal, and community‐related indicators. Parametric studies are carried out to quantify the influence of different seismic hazard scenarios, agent characteristics, and power dispatch strategies on the EPSS–community seismic resilience. The use of the agent‐based modeling framework enabled a rational formulation of the postearthquake recovery phase and highlighted the interaction between the EPSS and the community in the recovery process not quantified in resilience models developed to date. Furthermore, it shows that the resilience of different community sectors can be enhanced by different power dispatch strategies. The proposed agent‐based EPSS–community system resilience quantification framework can be used to develop better community and infrastructure system risk governance policies.  相似文献

This paper draws upon international research evidence that suggests a relationship between protest masculinity and the manifestation of violent crime among young males, and that criminal desistance may be linked to (inter-) subjective processes such as the reconstruction of masculine identity. The paper considers the potential that pugilism (the art and practice of boxing) may have on enabling young, disadvantaged minority male gang members to find avenues for alternative identity construction and to gain transitional experiences which trigger self-confessed desistance actions. Drawing upon an ethnographic study conducted in a boxing rehabilitation centre on the outskirts of Copenhagen, Denmark, the paper reports on data gleaned from participant observation and qualitative interviews with 22 ethnic minority young men. Findings suggest that the masculine context within the rehabilitation programme provided the young men with a safe space to perform broader versions of locally dominated views on masculinity and to reflect on their current situations and dilemmas. The young men were clearly in transition and their desistance journeys were characterized by hope and ambition but also disappointment and despair. In some cases it appeared that the young men's dogged attempts to desist from crime became a new way for them to ‘do masculinity’. The authors draw upon the findings to make recommendations for policy, practice and research.  相似文献

外商直接投资(FDI)在拓宽国内资金需求渠道的同时,具有较强的技术溢出效应,迎合了装备制造业资本和技术密集的双重特征。当前,安徽省装备制造业处在资本密集型占主导的发展阶段,对 FDI的偏好性较强。研究表明,安徽省装备制造业与FDI间具有较强的相关性,FDI能够有效促进安徽省装备制造业发展,但安徽省装备制造业对FDI的吸引力较弱,且各具体行业对 FDI依赖程度存在较大差异。据此提出相应的建议,一方面,安徽省应注重装备制造业转型升级,提升行业整体竞争力;另一方面,要优化投资环境,增强安徽省装备制造业对FDI的引致能力。  相似文献

为研究是否考虑设备 结构动力相互作用在不同地震阶段的差别,对建筑结构中常见的设备 结构相互作用体系进行了小震、中震和大震阶段的地震时程反应分析。分析了不同震级作用下考虑相互作用后给结构与设备的地震反应带来的变化。结果表明:考虑设备 结构动力相互作用与不考虑相互作用相比,结构的地震反应有较明显的区别,设备的地震反应有很大的区别,处于完全失真的状态。大震阶段由于设备和结构均进入了弹塑性阶段,刚度等主要参数发生了变化,导致动力相互作用的影响降低。虽然设备质量占结构总地震质量的比例很小,但仍会对结构位移与内力造成较大的影响。  相似文献

The looming oil crisis, pollution, and climate change have pushed governments, corporations, and individuals to think of new policies, new objects/products and new manners to market them – usually under the label of “green economy” (or the shifting towards a sustainable economy).

The changes that are on the way as a result of the envisaged “green revolution” need a broad vision that couples the economy of energetic techniques with the related socio-cultural economy that is induced by, and at the same time reciprocally influences, the mere technical transformations.

Based on previous analysis of theories of socio-technological change and putting at its center the concept of subjectivation in social sciences, this article proposes a theoretical understanding of cultural shifts and their relationship with changes in the practices of production, transfer and use of energy.

First part presents a schema of subjectivation in triangulation, that links the biological level with the material culture and with the representational realm of normativities in our society. It will be developed through the example of electric vehicle as metaphor of the energetic transition. Through this understanding, second part deals with the modeling of the three items as a processual energetic system by using the concepts of surplus and expenditure. Within this frame, we show how disruptions in one of the poles of this model influences the others and bring about changes in the entire Anthropo-Social level. Third part proposes possible types of emerging subjectivities and advances the idea of extending the realm of consciousness to the energetic transfers and their potentiality.  相似文献

在汉阳铁厂建设问题上,长期以来,学界普遍认为,张之洞选购炼钢设备时盲目自大,颟顸无知,以至于设备不符合原料品质,造成了严重后果,因之对张之洞非议颇多。其实,这些批评都脱离了当时的实际情形。张之洞根据汉阳铁厂的产品质量要求,立足于大冶铁矿石的化验数据,以此作为订购炼钢设备的依据。后来汉阳铁厂钢铁产品含磷过高的问题是多种因素综合作用的结果,不能简单地归咎于设备购买环节;同时,今人也不应该过分夸大由炼钢设备所引发的消极影响。  相似文献
