Model updating concerns the modification of an existing but inaccurate model with measured data. For models characterized by quadratic pencils, themeasured data usually involve incomplete knowledge of natural frequencies, mode shapes, or other spectral information. In conducting the updating, it is often desirable tomatch only the part of observed data without tampering with the other part of u...

Load theory of attention proposes that distractor processing is reduced in tasks with high perceptual load that exhaust attentional capacity within task-relevant processing. In contrast, tasks of low perceptual load leave spare capacity that spills over, resulting in the perception of task-irrelevant, potentially distracting stimuli. Tsal and Benoni (2010) find that distractor response competit...

The challenge of human-computer interaction forces educationalists to think of new ways to understand the social, historical and contextual nature of learning. Discussion and exchange of ideas enable learners to learn together. However, the granularity of the Webbased learning context is extensive; consequently, eCourseware design faces new dilemmas. Only through targeted research will it be kn...

Two experiments investigated whether outcomes that violate people’s moral standards increase their deviant behavior (the moral spillover effect). In Study 1, participants read about a legal trial in which the outcome supported, opposed or was unrelated to their moral convictions. Relative to when outcomes supported moral convictions, when outcomes opposed moral convictions people judged the out...

The paper examines risk spillover among major European, American and Japanese stock exchanges using daily stock prices from 1998 to 2011 period. More specifically, we focus more on risk spillover among major north-western stock markets (i.e. France, Germany, and United Kingdom) and southern European stock markets (Greece, Italy, Portugal, and Spain). The main motivation of the study is to use t...

World Bank Policy Research Working Paper 2972, February 2003 The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordi...

This three-week longitudinal field study with an experimental intervention examines the association between daily events and employee stress and health, with a specific focus on positive events. Results suggest that both naturally occurring positive work events and a positive reflection intervention are associated with reduced stress and improved health, though effects vary across momentary, la...

Urban areas consume up to 80 percent of the world's total energy production and are growing in size and complexity. At present, urban building energy consumption is largely considered solely in terms of individual building types, neglecting the effects of residents’ location-based activities that influence patterns in energy supply and demand. Here, we examine the spatial fluctuations of these ...

The effects of process and product innovation are analyzed in a multisectoral framework. The effect of an innovation in any particular sector propagates throughout the entire economy. A simple measure for the spillover of innovation effects to the other sectors is developed. As a consequence, an alternative viewpoint is obtained for the interpretation of the elements of the Leontief inverse and...

Four foreign exchange spot rate series, recorded on an hourly basis for a six-month period in 1986 are examined. A seasonal GARCH model is developed to describe the time-dependent volatility apparent in the percentage nominal return of each currency. Hourly patterns in volatility are found to be remarkably similar across currencies and appear to be related to the opening and closing of the worl...
