The Georgia Coast of the eastern United States boasts some largest and spatially complex Late Archaic sites in North America, with most famous these being shell rings. ring village phenomenon its larger ceremonial landscapes did not, however, last throughout Archaic. Climate shifts that led to local relative sea level change area at around 3800 cal. BP appears have resulted conditions suppresse...

We use multidimensional diffusion processes to approximate the dynamics of a queue served by many parallel servers. The queue is served in the first-in-first-out (FIFO) order and the customers waiting in queue may abandon the system without service. Two diffusion models are proposed in this paper. They differ in how the patience time distribution is built into them. The first diffusion model us...

Abstract Human impacts have led to dramatic biodiversity change which can be highly scale‐dependent across space and time. A primary means manage these changes is via passive (here, the removal of disturbance) or active (management interventions) ecological restoration. The recovery biodiversity, following disturbance, often incomplete relative some kind reference target. magnitude systems dist...

This study explores the reason for non-usage and abandonment of microblogging. While previous studies mainly focused on individual behaviors associated with the use of social media, this research identifies why people do not use, or terminate their microblogging accounts. Studying the reasons for non-usage and abandonment is important as it helps organizations devise strategies to counteract th...

We characterized soil cation, carbon (C) and nitrogen (N) transformations within a variety of land use types in the karst region of the northeastern Dominican Republic. We examined a range of soil pools and fluxes during the wet and dry seasons in undisturbed forest, regenerating forest and active agricultural sites within and directly adjacent to Los Haitises National Park. Soil moisture, soil...

Many-server queuing networks with general service and abandonment times have proven to be a realistic model for scenarios such as call centers and health-care systems. The presence of abandonment makes analytical treatment difficult for general topologies. Hence, such networks are usually studied by means of fluid limits. The current state of the art, however, suffers from two drawbacks. First,...
