Previous studies on moral judgment have assumed that the trolley and footbridge dilemmas (Thomson, 1985) reflect utilitarian and deontologist thinking, respectively. However, on the basis of the “intervention myopia” hypothesis (Waldmann & Dieterich, 2007) and recent findings in analyses of moral dilemmas (Nakamura, 2011), the current study led a somewhat paradoxical prediction: An effect of th...

To perform a realistic reliability analysis of a complex cable-stayed steel footbridge subject to natural hazard and corrosion, this article addresses a rational process of modeling and simulation based on identification, model updating, and validation. In particular, the object of this study is the Ponte del Mare footbridge located in Pescara, Italy; this bridge was selected as being a complex...

This paper presents a probabilistic damage identification study on a full-scale structure, the Dowling Hall Footbridge, through a Bayesian finite element (FE) model updating. The footbridge is located at Tufts University and is equipped with a continuous monitoring system that measures its ambient acceleration response. A set of data is recorded once every hour or when triggered by large vibrat...

Moral psychologists have shown that people’s past moral experiences can affect their subsequent moral decisions. One prominent finding in this line of research is that when people make a judgment about the Trolley dilemma after considering the Footbridge dilemma, they are significantly less likely to decide it is acceptable to redirect a train to save five people. Additionally, this ordering ef...

In this paper, effects of changing ambient temperatures on finite element (FE) model updating of the Dowling Hall Footbridge are investigated. The Dowling Hall Footbridge is located on the Tufts University campus in Medford, Massachusetts. The footbridge is equipped with a continuous monitoring system that records vibration and temperature of the bridge once an hour or when triggered by large v...

Many moral psychologists have proposed that the difference between people’s moral judgments about the Trolley and Footbridge dilemmas can be explained by their differing emotional responses to the dilemmas. In two experiments, we tested this explanation by presenting the dilemmas and measuring participants’ reactions using a self-report emotion measure (PANAS-X). As might be expected, participa...

Although moral dilemmas such as the trolley and footbridge dilemmas (Thomson, 1986) have been widely employed to investigate the nature of moral reasoning, but their psychometric properties remain a mystery. In this study, 219 participants completed 62 moral dilemma tasks used in Greene et al. (2001), and the correlation structure among the dilemmas was analyzed through factor analysis and stru...

The paper summarises the ambient vibration-based assessment of an historic suspension footbridge, dating back to 1928. The footbridge is characterised by the timber floor system supported by two couples of cables, that were recently replaced. After the retrofit, the actual structural behaviour of the bridge were assessed by experimental and theoretical methods. The field tests included geometri...

Modern footbridges are often lively structures, characterized by natural frequencies that fall in the range of pedestrian activities, such as walking, running, and jumping. Therefore, serviceability assessment under human-induced excitation is crucial both at design stage during footbridge lifetime. This paper presents validates two different FE models an existing with very complex geometry: St...

Tensegrity structures are spatial reticulated structures composed of cables and struts. A tensioncompression equilibrium leads to lightweight systems that change shape through length changes in their members. Active members thus control several degrees of freedom simultaneously. Tensegrityring modules are transformable circuit-pattern modules. The linear combination of tensegrity rings has been...
