The Firefighter problem and a variant of it, known as Resource Minimization for Fire Containment (RMFC), are natural models for optimal inhibition of harmful spreading processes. Despite considerable progress on several fronts, the approximability of these problems is still badly understood. This is the case even when the underlying graph is a tree, which is one of the most-studied graph struct...

firefighting is extremely strenuous and physically demanding work and involves ability to cope with emergency life-or-death situations. because of the high physical demands of firefighting, successful job performance and minimizing of morbidity and mortality depends on fitness for duty. the firefighting department of tehran does not perform periodic medical assessment for firefighters. the aim ...

In this paper we describe a functional goal decomposition of urban firefighting as part of a larger cognitive task analysis. Previous research indicates that firefighter decision strategies employ a pattern-matching technique that allows them to choose the first workable option based on similar previous experiences. This study builds upon this research by employing multiple cognitive task analy...

In the firefighter problem the spread of fire is modelled on an undirected graph. The goal is to find such an assignment of firefighters to the nodes of the graph that they save as large part of the graph as possible. In this paper a multi-objective version of the firefighter problem is proposed and solved using an evolutionary algorithm. Two different autoadaptation mechanisms are used for gen...

Three experiments were conducted with male-confederates wearing or not a firefighter’s uniform. In the first experiment, male confederates smiled to young women whereas in the second experiment male-confederates said “hello” to young women in the street. The results shown that’s women smiled more favorably and more openly and said “hello” more favorably to the firefighter. In the third experime...

24 A cornerstone of effective institutional learning and accountability is the development, tracking, and analysis of informative performance measures. In a previous issue of Fire Management Today (“A New Look at Risk Management,” Winter 2011), a series of articles highlighted the importance of organizational safety and risk management and the challenges of balancing safety, efficiency, and eff...

Firefighters routinely encounter physical demands that contribute to countless musculoskeletal injuries. Seemingly, a progressive prescription for fitness would offer superior protection against intrinsic job risks. The purpose of this study was to investigate the influence of two resistance training interventions on fitness adaptations among firefighters, and to assess the degree of transfer t...

Background: Inflammation is increasingly recognized as an important component of tumorigenesis, although the mechanisms involved are not fully characterized. The invasive capacity of cancers is reflected in the classic metastatic cascade: tumor (T), node (N) and metastasis (M). However, this staging system for cancer would also have a tumoral biological significance. Presentation of the hypothe...

OBJECTIVE We evaluated the current use and fit of structural firefighting gloves and developed an improved sizing scheme that better accommodates the U.S. firefighter population. BACKGROUND Among surveys, 24% to 30% of men and 31% to 62% of women reported experiencing problems with the fit or bulkiness of their structural firefighting gloves. METHOD An age-, race/ethnicity-, and gender-stra...
