OBJECTIVE To (1) provide a contextual analysis of the Caribbean region with respect to forces shaping the current and emerging nursing workforce picture in the region; (2) discuss country-specific case(s) within the Caribbean; and (3) describe the Managed Migration Program as a potential framework for addressing regional and global nurse migration issues. PRINCIPAL FINDINGS The Caribbean is i...

Most corals in tropical localities broadcast their gametes into the water column, yet we have a poor understanding of what forces reproductive schedules. Moreover, recent studies show considerable geographical variation in the duration of the coral spawning season. For example, on the Great Barrier Reef, corals display tight coupling, while corals in Kenya spawn over seven months. This study re...

Disentangling evolutionary forces that may interact to determine the patterns of genetic differentiation within and among wild populations is a major challenge in evolutionary biology. The objective of this study was to assess the genetic structure and the potential influence of several ecological variables on the extent of genetic differentiation at multiple spatial scales in a widely distribu...

Mechanical forces play an important role during brain development. In the early embryo, the anterior end of the neural tube enlarges and differentiates into the major brain subdivisions, including three expanding vesicles (forebrain, midbrain, and hindbrain) separated by two constrictions. Once the anterior neuropore and the spinal neurocoel occlude, the brain tube undergoes further regional gr...

Similar to random sea waves, forces on the offshore structures due to waves are random. These forces can be mainly divided into two components, namely, inline forces and transverse or lift forces. The random nature of lift forces is more complicated than that of inline forces and both should be combined for design purposes. In the present paper, two different approaches have been used to determ...

Current regional hurricane loss estimation models use the present-day vulnerability of the building inventory in predicting future losses and assume that it remains static throughout the time horizon of interest. In reality, the hurricane vulnerability of a region changes with time due to changes in the types and conditions of buildings. Loss estimation models, therefore, may misestimate risk a...

Although there is evidence that domestic politics matter for the formation of preferential trade agreements, the impact of large-scale changes in political institutions, especially in the direction of democratization, on economic integration has been given surprisingly short shrift in the previous literature. This study takes a first step toward developing such an explanation. It posits that, a...
