Citizenship, Identity, And Transnational Migration: Arab Immigrants To The Us, Caroline R. Nagel, Lynn A. Staeheli
Citizenship, Identity, And Transnational Migration: Arab Immigrants To The Us, Caroline R. Nagel, Lynn A. Staeheli
Faculty Publications
The aim of this paper is to evaluate the changing relationships between identities, citizenship and the state in the context of globalisation. We first examine the ways in which scholars discuss changes in the ways in which citizenship and political identity are expressed in the context of international migration. We argue that much of the discussion of transnationalism and diaspora cling to an assumption that citizenship remains an important—though not defining—element of identity. Our position, by contrast, is that migration is one of a number of processes that transform the relationship between citizenship and identity. More specifically, we argue that …

Accuracy Of Airborne Lidar-Derived Elevation: Empirical Assessment And Error Budget, Michael E. Hodgson, Patrick Bresnahan
Accuracy Of Airborne Lidar-Derived Elevation: Empirical Assessment And Error Budget, Michael E. Hodgson, Patrick Bresnahan
Faculty Publications
As part of a countywide large-scale mapping effort for Richland County, South Carolina, an accuracy assessment of a recently acquired lidar-derived data set was conducted. Airborne lidar (2-m nominal posting) was collected at a flying height of 1207 meters above ground level (AGL) using an Optech ALTM (Airborne Laser Terrain Mapper) 1210 system. Unique to this study are the reference point elevations. Rather than using an interpolation approach for gathering observed elevations at reference points, the x-y coordinates of lidar points were located in the field and these elevations were surveyed. Using both total-station-based and rapid-static GPS techniques, observed vertical …
A Parameterization Model For Transportation Feature Extraction, Michael E. Hodgson, Xingong Li, Yang Cheng
A Parameterization Model For Transportation Feature Extraction, Michael E. Hodgson, Xingong Li, Yang Cheng
Faculty Publications
This article presents one solution to the parameterization problem for automated road feature extraction models. Using a line-length buffer approach, a measure of agreement between extracted road features and reference road features is defined. An automated approach for deriving this agreement index is presented and implemented as a parameterization model. Coupling the implemented parameterization model with an existing transportation feature extraction model is demonstrated. Although the solution was designed for a road feature extraction model (FEM), the conceptual design could be applied to other linear FEMs, such as models for streams, fault lines, and isolines.
Pelvic Sexual Dimorphism In A Metatherian, Didelphis Virginiana: Implications For Eutherians, Robert G. Tague
Pelvic Sexual Dimorphism In A Metatherian, Didelphis Virginiana: Implications For Eutherians, Robert G. Tague
Faculty Publications
Eutherians give birth to relatively large infants. Females have larger pelves than males, though males typically have larger nonpelvic bones. Pelvic dimorphism is an adaptation for parturition. Metatherian females, who give birth to markedly small infants, should not show pelvic adaptations for parturition and should have smaller pelves than males. Adult females and males of the Virginia opossum, Didelphis virginiana, are compared. Males are significantly larger than females in absolute size for 14 of 16 pelvic and 8 nonpelvic measures. Sexes did not differ significantly for lower iliac length and posterior space of midplane. However, relative lengths for females are …
Synergistic Use Of Lidar And Color Aerial Photography For Mapping Urban Parcel Imperviousness, Michael E. Hodgson, John R. Jensen, Jason A. Tullis, Kevin D. Riordan, Clark M. Archer
Synergistic Use Of Lidar And Color Aerial Photography For Mapping Urban Parcel Imperviousness, Michael E. Hodgson, John R. Jensen, Jason A. Tullis, Kevin D. Riordan, Clark M. Archer
Faculty Publications
The imperviousness of land parcels was mapped and evaluated using high spatial resolution digitized color orthophotography and surface-cover height extracted from multiple-return lidar data. Maximum-likelihood classification, spectral clustering, and expert system approaches were used to extract the impervious information from the datasets. Classified pixels (or segments) were aggregated to parcels. The classification model based on the use of both the orthophotography and lidar-derived surface-cover height yielded impervious surface results for all parcels that were within 15 percent of reference data. The standard error for the rule-based per-pixel model was 7.15 percent with a maximum observed error of 18.94 percent. The …

During late spring through summer of 1994 and 1995, 290 randomly selected stream sites in Nebraska, Kansas, and Missouri were sampled once for several parameters including conductivity, turbidity, total phosphorus, nitrate-nitrite nitrogen, the index of biotic integrity, and a habitat index. Based on landscape data from watersheds that were delineated for each sampling location, interrelationships were examined between these water quality parameters and land use/land cover, the normalized difference vegetation index (NDVI), and vegetation phenological metrics derived from the NDVI. Statistically significant relationships were found between NDVI values and the derived metrics with the stream condition parameters (r values to …

Dam Nation: A Geographic Census Of American Dams And Their Large-Scale Hydrologic Impacts, William L. Graf
Faculty Publications
Newly available data indicate that darns fragment the fluvial system of the continental United States and that their impact on river discharge is several times greater than impacts deemed likely as a result of global climate change. The 75,000 dams in the continental United States are capable of storing a volume of water almost equaling one year's mean runoff, but there is considerable geographic variation in potential surface water impacts. In some western mountain and plains regions, darns can store more than 3 year's runoff, while in the Northeast and Northwest, storage is as little as 25% of the annual …

Variability Of A Vestigial Structure: First Metacarpal In Colobus Guereza And Ateles Geoffroyi, Robert G. Tague
Variability Of A Vestigial Structure: First Metacarpal In Colobus Guereza And Ateles Geoffroyi, Robert G. Tague
Faculty Publications
A tenet of evolutionary theory is that, under conditions of stabilizing selection, phenotypic variability is inversely related to selection intensity. Correspondingly, a nonfunctional, vestigial structure is expected to be highly variable relative to its functional homologue. This study tests the hypothesis that species with a vestigial pollex, Colobus guereza and Ateles geoffroyi, have a first metacarpal whose length is both highly variable relative to, and poorly correlated with, the lengths of the other metapodials. The results are consistent with the hypothesis, though this combination of traits is also found in Presbytis rubicunda and Presbytis cristata. The latter two species have …
