Abstract This study examined whether the Coast Guard and Maritime Transportation Act of 2006 affected the United States (US) Coast Guard performance characteristics with respect to incident response. The periods analyzed consisted of a decade before versus a decade after implementation of the legislation. Using analysis of variance (ANOVA) and the p-value approach (p < 0.05), six hypotheses were tested to determine whether statistically significant differences in response attributes existed during the 10 years before versus the 10 years following the passing of the legislation. Four significant hypothesis-testing outcomes represented differences in the number of incidents, incident responses, cumulative lives lost, and lives lost after notification.

Professional development is an essential aspect of any career. Many professions have minimum standards or requirements of training each year to maintain a license and/or job. This chapter outlines the necessary components for effective professional development training in terms of technology use, and examines some reasons why certain professional development programs may be ineffective. The chapter also discusses ways to assess the overall efficiency of a professional development program and highlight some outstanding professional development programs/practices in existence. A comparison between professional development practices performed in the United States with other countries around the world is provided to offer an understanding how professional development can vary depending upon culture.

Spiders vary enormously in their behaviour when placed on the surface of fresh water. In some families (e.g. Theridiidae), the spider typically becomes wet and either sinks or is incapacitated by adhesion to the water. In other families (e.g. Agelenidae), the spider remains dry and moves across the water using its legs in much the same way it does on land, with the members of each leg pair moving in alternation with each other. In at least one family (Pisauridae), the spider remains dry and moves across the water using a rowing or galloping gait in which the members of each propulsive pair of legs move in synchrony with each other. While some degree of hydrophobicity is widespread among spiders, the ability to move on water by rowing occurs rarely; it is common only among families in the Lycosoidea, which is a subset of the GST (Grate-Shaped Tapetum) clade. Our mapping of water surface locomotion behaviour of representatives of 42 families of spiders onto cladograms of the Araneae suggests that the ability to row evolved at the base of the clade that includes Trechaleidae, Pisauridae and Lycosidae and evolved independently in some members of the family Ctenidae. Rowing behaviour is seen in all subfamilies of Lycosidae but, unlike in the Pisauridae in which all animals tested showed the rowing behaviour, many individuals that could row did not do so all of the time. Among the 166 non-lycosoid species we have tested, we have found one species of Araneidae and two species of Salticidae that can row. It is evident from our data that, in most spiders, phylogeny trumps recent selection (based on habitat preference) in determining the spiders' locomotor behaviour on the water surface.
