Building contents that include cabinets housing electronic equipment are typically not rigidly secured to the floor, nor to the adjacent wall except in regions of high seismic activities. The behavior of unrestrained building contents in an earthquake is a cause of concern because of the consequence of damage to certain equipment or other forms of fragile items. Much of the research reported in the literature has been devoted to studying the rocking and sliding motion behavior of base-excited rigid objects and their risks of overturning. In contrast, this paper is concerned with estimating the impact acceleration that can be generated by the pounding of the rocking object onto the floor. Algebraic expressions for predicting the acceleration level, which can be translated into dynamic force values, are derived and illustrated by case studies. Importantly, the proposed expressions have been verified by comparisons with results from both simulated and physical experiments. In illustrating the use of the proposed analytical procedure, a parametric experimental study has been undertaken on a cushion material to study the sensitivity of its static and dynamic stiffness to changes in the boundary conditions of the cushion. The proposed calculation procedure, while simple to apply, can be used as a means of predicting shock and the dynamic forces that can be generated in an object in the course of the response to an earthquake. 相似文献

A study was conducted on a collection of 123 juvenile skeletons from various sites dating to the Bronze Age (Argar culture) and from the medieval cemeteries of La Torrecilla, Villanueva de Soportilla and San Baudelio, all in the Iberian Peninsula. No cranial trauma was observed. However, four postcranial fractures were found, including three from Castellón Alto, a typical Argaric village of some urban complexity built on steep terraces in high and rugged terrain. The combination of a hazardous environment and a climate that encourages outdoor play may explain the relatively high frequency of childhood trauma in the burials from the Argar culture.

Amidst the ongoing crisis of plummeting oil prices, the GCC (Gulf Cooperation Council) terrain has become a haunt of economists and financial analysts to tackle the ongoing challenges in the region. GCC constituents are gearing themselves with a robust political will that they hope could result in a turnaround of their economy by adopting a policy of economic diversification in nonoil‐based sectors. With this background supported by extensive qualitative scan of literature pertaining to the reforms proposed by the six members of the GCC to drive the economy forward amidst ongoing economic crisis, this article seeks to underscore the prospect of a shared initiative by the GCC constituents in institutionalizing a GCC bank as a potent innovative solution which may serve to provide an edifice for pushing forth the region's economy in nonhydrocarbon segments contingent upon the individual needs of the GCC constituents. As an exploratory study, this paper sheds light on these issues besides discussing the fundamental functions of the GCC bank. 相似文献

Academia is expected to act as a cognitive arena in which members intellectually challenge one another, problematize social structures, and destabilize dominant ideologies. It is, supposedly, a cognitively unstable environment wherein intellectualism pushes social boundaries and acts as an agent for social change. It is a training camp wherein people come to be trained in the practice of critical thinking. Hence, one would imagine that academia would be the last place to find passive conformism. However, does this image reflect reality? Having interviewed four groups of 50 students, 47 academics, and 28 support staff in three Saudi universities, passive conformism (be it unethical, managerial, or in the form of logistical conformism) appears to be a necessity in Saudi academia. This suggests that, although academia acts as an authority in regard to critical thinking, it may not internalize this philosophy or expose its own organizational activities to such thinking. Passive conformism in Saudi academic organizations is enhanced by wider Saudi culture which promotes conformism among its citizens and directs every aspect of public and private lives, including the lives of its academic organizations. A theoretical proposition could be therefore that passive conformism in a society could be transmitted to its organizations. 相似文献

Ecological modernisation (EM), in theory and practice, has increasingly become central to contemporary state environmental reform agendas. EM's allure lies in its central tenet that the contemporary institutions of capitalism can be ecologically adapted to achieve ‘win–win’ economic and environmental outcomes. How government policy can best accomplish this aim is contested, however, with weak and strong EM approaches advocating different roles for the state in facilitating ecological restructuring. The latter approaches argue that for EM processes to be successful, state intervention via ecological industrial policy is required. This article makes a unique contribution to the industry policy and EM debate by assessing the manner in which EM was conceptualised and implemented within the Australian government's automotive industry policy between 2007 and 2013. This analysis raises issues about the institutional capacity of states to pursue either weak or strong forms of EM.
生态现代化在理论上和实践上日益成为当代国家环境改革的中心议题。环境现代化所以诱人在于其核心原则:当代资本主义体制生态上可以取得经济、环境的双赢结果。不过政府政策如何实现这一目标确是挑战,生态现代化有强、弱二途,政府在促进生态重构时扮演不同的角色。按强势思路,要想生态现代化成功,需要国家通过生态产业政策进行干预。本文对2007至2013年澳大利亚政府的汽车产业政策形成和实施的方式做了评估,希望以此对产业政策以及生态现代化的辩论有所助益。本文还提出了国家实施强、弱生态现代化的体制能力的问题。 相似文献

This study looks at the reorganization of production in the context of a multi-plant firm in the automotive industry. Changes in such firms may result in the closure of some plants and/or the opening of others. The article provides a method for assessing the risk of plant closure, and then applies that method to a specific case: the automotive plants located in the Spanish region of Navarre. This entails acknowledging the factors that increase what has come to be known as the “degree of vulnerability” of the plant, including sunk costs and relative productivity levels. This paper can also be understood as a source of information for designing developmental after-care programmes for foreign direct investors in the periphery of the European Union. 相似文献

ABSTRACTThis article attempts to describe a particular form of baraccata house, found in L’Aquila, Italy. The differences between this form of baraccato and the Italian traditional timber-framed (T-F) structures, the baraccato borbonico and the baraccato alla beneventana, are shown. In the upper valley of the Aterno river (Abruzzo, Italy), a few kilometers far from L’Aquila, wonderful 18th-century examples of T-F masonry structures are present. The use of wood pervades both the poor and noble buildings. In this article, the documentary and functional features of this peculiar anti-seismic timber-based building technique, which is widespread in L’Aquila and the neighboring areas, is described. After a comparative analysis of the technique’s features, the case of three T-F buildings, belonging to three different social classes is reported, the first is the Ricci palace in Mopolino di Montereale, the second is a middle-class building, and the third is a rural one. The 1703 earthquake, which affected the upper valley of the Aterno river and the nearby city of L’Aquila, gave rise to an ante litteram anti-seismic culture. Timber was not seen as an obstacle to durability but a material to be exploited to protect buildings from earthquakes. 相似文献
