Fringe-Saving A* is an incremental version of A* that repeatedly finds shortest paths from a fixed start cell to a fixed goal cell in a known gridworld in case the traversability of cells changes over time. It restores the content of the OPEN and CLOSED lists of A* at the point in time when an A* search for the current search problem could deviate from the A* search for the previous search prob...

Preparing our hospitals and other healthcare facilities for disasters is a national security priority. Disasters occur nearly every day in the United States, and the frequency is increasing. This includes such diverse events as storms, droughts, wildfires, floods, earthquakes, chemical and industrial accidents, burns, mass shootings and bombings, and epidemics. All sickened or injured people re...

This article compares saving motives of urban Chinese and American workers. A framework based on Maslow’s human needs theory with the consideration of economic and cultural factors was used to develop hypotheses. The results of logistic regressions and simulations suggest that Chinese are more likely than Americans to report four out of six saving motives: saving for daily expenses, emergencies...

In this paper we study the parameterized complexity of the firefighter problem. More precisely, we show that Saving k-Vertices and its dual Saving All But k-Vertices are both W[1]-hard for parameter k even for bipartite graphs. We also investigate several cases for which the firefighter problem is tractable. For instance, Saving kVertices is fixed-parameter tractable on planar graphs for parame...

Gender differences in personal saving behaviors among single person households were investigated using the 2007 Survey of Consumer Finances (SCF). Determinants of short-term and regular saving behavior were found to differ by gender. Women (n = 702) were less likely to save in the short term if they were in poor health, while poor health did not significantly affect the short term saving of men...

The First International Conference on the Theory and Practices in Bio-water-saving (ICTPB) was held from May 21 to 25, 2006 in Beijing, China. This indicated that the work related to this hot topic on the globe has been paid more attention to. Most progress in this field has been presented from near 300 participating people worldwide, who were meeting together to discuss about the theory and pr...

Four studies tested the idea that saving money can buffer death anxiety and constitute a more effective buffer than spending money. Saving can relieve future-related anxiety and provide people with a sense of control over their fate, thereby rendering death thoughts less threatening. Study 1 found that participants primed with both saving and spending reported lower death fear than controls. Sa...

This paper examines how aversion to risk and aversion to intertemporal substitution determine the strength of the precautionary saving motive in a two-period model with Selden/Kreps-Porteus preferences. For small risks, we derive a measure of the strength of the precautionary saving motive which generalizes the concept of "prudence" introduced by Kimball (1990b). For large risks, we show that d...

Although research has shown that poor people in sub-Saharan Africa (SSA), including those living in rural areas save, little is known about the factors that influence saving and asset accumulation among this population. Using three theoretical perspectives on saving and asset accumulation, this study examines the broader determinants of saving and asset accumulation among low-income individuals...
