Spatial Information Divergence: Using Global And Local Indices To Compare Geographical Masks Applied To Crime Data, Ourania Kounadi, Michael Leitner Oct 2015

Spatial Information Divergence: Using Global And Local Indices To Compare Geographical Masks Applied To Crime Data, Ourania Kounadi, Michael Leitner

Faculty Publications

Advances in Geographic Information Science (GISc) and the increasing availability of location data have facilitated the dissemination of crime data and the abundance of crime mapping websites. However, data holders acknowledge that when releasing sensitive crime data there is a risk of compromising the victims' privacy. Hence, protection methodologies are primarily applied to the data to ensure that individual privacy is not violated. This article addresses one group of location protection methodologies, namely geographical masks that are applicable for crime data representations. The purpose is to identify which mask is the most appropriate for crime incident visualizations. A global divergence …


The Human Shoulder Suspension Apparatus: A Causal Explanation For Bilateral Asymmetry And A Fresh Look At The Evolution Of Human Bipedality, Michelle L. Osborn, Dominique G. Homberger Sep 2015

The Human Shoulder Suspension Apparatus: A Causal Explanation For Bilateral Asymmetry And A Fresh Look At The Evolution Of Human Bipedality, Michelle L. Osborn, Dominique G. Homberger

Faculty Publications

© 2015 Wiley Periodicals, Inc. The combination of large mastoid processes and clavicles is unique to humans, but the biomechanical and evolutionary significance of their special configuration is poorly understood. As part of the newly conceptualized shoulder suspension apparatus, the mastoid processes and clavicles are shaped by forces exerted by the musculo-fascial components of the cleidomastoid and clavotrapezius muscles as they suspend the shoulders from the head. Because both skeletal elements develop during infancy in tandem with the attainment of an upright posture, increased manual dexterity, and the capacity for walking, we hypothesized that the same forces would have shaped …


Infectious Disease And Red Wolf Conservation: Assessment Of Disease Occurrence And Associated Risks, Kristin E. Brzeski, Rebecca B. Harrison, William T. Waddell, Karen N. Wolf, David R. Rabon, Sabrina S. Taylor Aug 2015

Infectious Disease And Red Wolf Conservation: Assessment Of Disease Occurrence And Associated Risks, Kristin E. Brzeski, Rebecca B. Harrison, William T. Waddell, Karen N. Wolf, David R. Rabon, Sabrina S. Taylor

Faculty Publications

Infectious diseases pose a significant threat to global biodiversity and may contribute to extinction. As such, establishing baseline disease prevalence in vulnerable species where disease could affect persistence is important to conservation. We assessed potential disease threats to endangered red wolves (Canis rufus) by evaluating regional (southeastern United States) disease occurrences in mammals and parasite prevalence in red wolves and sympatric coyotes (Canis latrans) in North Carolina. Common viral pathogens in the southeast region, such as canine distemper and canine parvovirus, and numerous widespread endoparasites could pose a threat to the red Wolf population. The most prevalent parasites in red …


Lithium In Drinking Water And Suicide Mortality: Interplay With Lithium Prescriptions, Marco Helbich, Michael Leitner, Nestor D. Kapusta Jul 2015

Lithium In Drinking Water And Suicide Mortality: Interplay With Lithium Prescriptions, Marco Helbich, Michael Leitner, Nestor D. Kapusta

Faculty Publications

Background: Little is known about the effects of lithium intake through drinking water on suicide. This intake originates either from natural rock and soil elution and/or accumulation of lithium-based pharmaceuticals in ground water. Aims: To examine the interplay between natural lithium in drinking water, prescribed lithium-based pharmaceuticals and suicide in Austria. Method: Spatial Bayesian regressions for males, females and pooled suicide mortality rates were estimated. Results: Although the expected inverse association between lithium levels in drinking water and suicide mortality was confirmed for males and for total suicide rates, the relationship for females was not significant. The models do not …

Hurricane Risk Variability Along The Gulf Of Mexico Coastline, Jill C. Trepanier, Kelsey N. Ellis, Clay S. Tucker Mar 2015

Hurricane Risk Variability Along The Gulf Of Mexico Coastline, Jill C. Trepanier, Kelsey N. Ellis, Clay S. Tucker

Faculty Publications

Hurricane risk characteristics are examined across the U. S. Gulf of Mexico coastline using a hexagonal tessellation. Using an extreme value model, parameters are collected representing the rate or λ (frequency), the scale or σ (range), and the shape or ζ (intensity) of the extreme wind distribution. These latent parameters and the 30-year return level are visualized across the grid. The greatest 30-year return levels are located toward the center of the Gulf of Mexico, and for inland locations, along the borders of Louisiana, Mississippi, and Alabama. Using a geographically weighted regression model, the relationship of these parameters to sea …

Ant Community Structure And Response To Disturbances On Coastal Dunes Of Gulf Of Mexico, Xuan Chen, Benjamin Adams, Cody Bergeron, Alexander Sabo, Linda Hooper-Bùi Feb 2015

Ant Community Structure And Response To Disturbances On Coastal Dunes Of Gulf Of Mexico, Xuan Chen, Benjamin Adams, Cody Bergeron, Alexander Sabo, Linda Hooper-Bùi

Faculty Publications

Coastal dunes are complex and fragile ecosystems. The decrease in environmental stressors from sea to inland creates zonation patterns of habitats, which support high biodiversity. Although coastal dunes have been examined in primary succession studies for more than 100 years, invertebrates have received much less attention than other taxa. In this study, we examined ant community composition and its relationship with vegetation structure on dunes, and used ants as indicators to reveal the influence of anthropogenic disturbances on these habitats. Quadrat sampling, hand collecting, and beating plants were used to sample ants on coastal dunes fringing the northern Gulf of …

African Fire Cultures, Cattle Ranching, And Colonial Landscape Transformations In The Neotropics, Andrew Sluyter, Chris Duvall Jan 2015

African Fire Cultures, Cattle Ranching, And Colonial Landscape Transformations In The Neotropics, Andrew Sluyter, Chris Duvall

Faculty Publications

Fire regimes emerge partly from human activities that reflect cultural-ecological knowledge of the relationships among fire, vegetation, grazing, climate, and other variables, as well as social relations. More knowledge of such “fire cultures,” past and present, therefore remains necessary to better understand the causes and persistent consequences of landscape burning. In the neotropics, people have used fire for centuries to manage livestock pastures. Conventional wisdom has long posited that such practices derived solely from antecedent European and indigenous, Native American fire cultures. Analysis of accounts of rangeland burning from throughout the neotropics during colonial times, however, demonstrates that ranchers incorporated …

Annual average and maximum spells with no precipitation in the southern United States are analyzed. In this study, dry spells are defined as consecutive days with no measurable rainfall. The study area includes 70 weather stations in Texas, Oklahoma, Louisiana, Arkansas, Mississippi, and Tennessee. Interarrival times between daily precipitation records for each station provide the data for this analysis. All 70 stations were analyzed from 1950 to 2013. Six stations that each have data for more than 100 years were analyzed for the period from 1908 to 2013. Approximately 25% of stations in the region show significant negative trends through …


Examining Healthy Food Accessibility In Baton Rouge, Louisiana Using A Huff-Modified 2sfca Method, Xuan Kuai Jan 2015

Examining Healthy Food Accessibility In Baton Rouge, Louisiana Using A Huff-Modified 2sfca Method, Xuan Kuai

LSU Master's Theses

Food accessibility refers to people’s ability to access the service of food providers. Disparities in healthy food accessibility have long been a public health concern. This study proposes a new approach modified from the popular 2-Step Floating Catchment Area (2SFCA) method to measure spatial access. By incorporating a self-adaptive kernel density function extracted from the Huff Model, the proposed new method is termed the Huff-modified 2SFCA method. It is then applied to measure the healthy food accessibility in East Baton Rouge Parish, Louisiana. The research accounts for the economically disadvantaged groups that may walk or depend on public transit for …


Comparison Of Occlusal Area And Postcanine Mesiodistal Length In Old World And New World Monkeys, Ashley Marie Franklin Jan 2015

Comparison Of Occlusal Area And Postcanine Mesiodistal Length In Old World And New World Monkeys, Ashley Marie Franklin

LSU Master's Theses

The purpose of this study is to discover the relationship between the number of teeth and the postcanine occlusal area and postcanine mesiodistal length in select OWM and NWM species. New World monkeys (NWM) have 12 premolars, whereas Old World monkeys (OWM) have 8. Four species are studied: Cercopithecus albogularis and Colobus guereza (OWM), and Cebus capucinus and Alouatta palliata (NWM). Two pairs of species are chosen because they are classified as having the same general folivorous and omnivorous diet: Co. guereza and A. palliata, and Cer. albogularis and Ceb. capucinus, respectively. Adult, wild caught, female specimens from the Smithsonian, …


Visual Representations Of Gender In Engineering Trade Journals Of Professional Societies During 1998-2012: A Content Analysis Of Hierarchy And Stereotypes, Tracy Ettel Morris Jan 2015

Visual Representations Of Gender In Engineering Trade Journals Of Professional Societies During 1998-2012: A Content Analysis Of Hierarchy And Stereotypes, Tracy Ettel Morris

LSU Doctoral Dissertations

Recruiting and retaining women in engineering have stagnated since the mid-1990's partially due to the marginalization of women in education and the workforce. This research analyzed the quality and quantity of representation of women and men in visual images of professional science and engineering trade journals to illuminate the marginalizing climate of engineering. A mixed methods approach using visual content analysis was performed for a 15-year period during 1998-2012 of three different trade journals of professional societies representing various disciplines of engineering: the first has a low percentage of women, the second has a higher percentage of women, and the …

The study area is the Mississippi State, which is ranked last state for health care. The objectives of this study are to calculate the accessibility and analyze the spatial and non-spatial disadvantages of communities in accessibility of primary health care …


The Saxophone In Puerto Rico: History And Annotated Bibliography Of Selected Works, Marcos David Colón-Martín Jan 2015

The Saxophone In Puerto Rico: History And Annotated Bibliography Of Selected Works, Marcos David Colón-Martín

LSU Doctoral Dissertations

The tradition of classical saxophone performance in Puerto Rico officially began quite recently in 1994. Musicians performing regularly in the style are few and local composition of new music for the instrument is rare. This research provides a historical overview of the saxophone in the musical culture of Puerto Rico and explores reasons for the delay on saxophone classical performance to develop. In an attempt to help promote the local performance and composition of new works, the author provides an annotated bibliography of music for saxophone by selected Puerto Rican composers.


Planning Towards Equal Spatial Accessibility Of Nci Cancer Centers Across Geographic Areas And Demographic Groups In The U.S., Cong Fu Jan 2015

Planning Towards Equal Spatial Accessibility Of Nci Cancer Centers Across Geographic Areas And Demographic Groups In The U.S., Cong Fu

LSU Doctoral Dissertations

The Cancer Centers designated by the National Cancer Institute (NCI) form the “backbone” of the cancer care system in the United States. Awarded via a peer-review process and being re-evaluated every 3 to 5 years, an NCI Cancer Center receives substantial financial support from NCI grants. When the quality standard is not compromised, we argue that an additional criterion for improving and promoting equal accessibility should be factored into the designation and planning process of NCI Cancer Centers. With the help of regression and dummy variables, this research evaluates geographic disparities in spatial accessibility of the NCI Cancer Centers across …


Mortuary Practices And Social Identity At Matrix 101, La Leche Valley, Peru, Jenna Renee Hurtubise Jan 2015

Mortuary Practices And Social Identity At Matrix 101, La Leche Valley, Peru, Jenna Renee Hurtubise

LSU Master's Theses

This thesis focuses on the social identity of the individuals buried at a Late Middle Sicán (A.D. 1050-1120) mass grave designated Matrix 101. Matrix 101 is located in the Great Plaza of the Pomac forest archaeological complex in the La Leche Valley, north coast of Peru. My objectives are threefold: (1) to understand the social identities of the individuals, (2) to examine the complex mortuary practices that took place during the construction of the burial, and (3) to infer socio-political reasons for the construction of Matrix 101 and to see how they might relate to the Sicán societal collapse. Initial …
