Lithic analysis of three Lowland Virgin Anasazi sites
… assemblages ever done. Comparisons reveal a temporal trend toward increasing sedentism at the early to middle Pueblo II interfacing time period. This finding may be important to future arguments for fully sedentary Virgin Anasazi communities.

Object-centric temporal navigation for dynamic information visualizations.
We introduce object-centric temporal navigation for time-varying information visualizations. In our approach, navigation through time is controlled by interacting directly with any data item, enabling simultaneous exploration of the time dimension while focusing on the changing item. Subtle …

Has global financial reporting comparability improved?
… accounting numbers, this study examines the temporal trend in global financial reporting comparability and the factors that explain its variation. Despite regulatory interest in improving comparability, numerous frictions can limit the effectiveness of these efforts; examples include …

Lagoon effluent treatment using grass filtration bays
… and cracks in the soil. The trials showed a temporal trend in most of the monitored parameters. Ammonia, total nitrogen, total phosphorus, and BOD removals were generally higher during the first half of the trial period, while effluent colour was poorer during the first three and last five …

Evaluating the sustainability of monitored natural attenuation in groundwater at chlorinated ethene contaminated sites
… thesis where NAC is the screening metric and the temporal trend in the rate of natural attenuation being evaluated. Within the conceptual decision model, the use of NAC as a screening tool in combination with a specific analysis of MNA parameters allows engineers, regulators, and decision makers …

Analysis of Post-Cranial Traits for the Assessment of Biological Distance among Temporally Distinct New World Populations of African Descent
… change in post-cranial osteometric markers in temporally distinct New World populations of African ancestry: Newton Plantation series (17th-19th century Barbados; N = 16); two subsamples from the Hamann-Todd (HT) series (U.S.) based on birth year, 1865-1900 (N = 66) and 1901-1915 (N = 62); and …

Spatial characteristics of the remotely-sensed surface urban heat island in Baton Rouge, LA: 1988-2003
… high-resolution (both spatially and temporally) observations in cities. Using remotely-sensed data, this study analyzes urban heat islands (UHI) that are manifested through an elevation in the surface thermal emissions within urban regions known as surface heat islands (SHI). The …

Models and methods for computationally efficient analysis of large spatial and spatio-temporal data
… methods and models for large spatial and spatio-temporal data. Several approximation methods to "the big n problem" are reviewed, and an extended autoregressive model, called the EAR model, is proposed as a parsimonious model that accounts for smoothness of a process collected over space. It is …
