Exploring Influences On Gender Equality In Photojournalism: Is The Field Picture-Perfect?, Andrea Briscoe Jan 2014

Exploring Influences On Gender Equality In Photojournalism: Is The Field Picture-Perfect?, Andrea Briscoe

LSU Master's Theses

America prides itself on having a free press. Ideally, this free press would look like the communities in which they cover. However, research shows that gender discrepancies are quite common in newsrooms (Anderson 2014; Briscoe 2012; Norris 1997; Willnat and Weaver 2014). Women often have a marginal presence in newsrooms, and this is troublesome, because scholars have noted that men and women approach newsgathering and reporting differently (Beam and Cicco 2010; Briscoe 2012; Grabe et al. 2011; Weaver 1997). While research has focused on gender discrepancies in various types of media, little to no research has looked at the field …

Early Horizon Defensive Structures And The Role Of Warfare In The Lower Nepeña Valley, Peru, James Steven Treloar Jan 2014

Early Horizon Defensive Structures And The Role Of Warfare In The Lower Nepeña Valley, Peru, James Steven Treloar

LSU Master's Theses

In this thesis I examine the presence and distribution of defensive structures in Nepeña, Ancash, Peru, during the Early Horizon (ca. 900-200 B.C.). Data are gathered from pedestrian surveys, GPS coordinates, drawings, and photographs. I analyze architectural and spatial data using Geographic Information Systems (GIS) tools. I integrate these methods to investigate the organization and distribution of defensive structures in the lower Nepeña, in particular at the archaeological complexes of Caylán, Samanco, and Huambacho. Caylán is a multi-component archaeological complex with a major Early Horizon occupation, and serves as the primary site while the others are used to draw a …

The Frontal Bone As A Proxy For Sex Estimation In Humans: A Geometric Morphometric Analysis, Lucy Ann Edwards Hochstein Jan 2014

The Frontal Bone As A Proxy For Sex Estimation In Humans: A Geometric Morphometric Analysis, Lucy Ann Edwards Hochstein

LSU Master's Theses

Physical anthropologists have a toolkit for determining sex from skeletal remains composed of visual and metric techniques concerning the pelvis and the skull. However, complete elements are not always available and results can be indeterminate. The present study combines visual assessment of the skull with statistical methods of shape analysis, geometric morphometrics, to reach a better understanding of how cranial variation of the frontal bone is influenced by sex. The three-dimensional coordinates of frontal bone curvatures of 204 skulls from the Terry Collection were collected using a Microscribe digitizer. These data were used to assess the ability of this technique …

Electrical Resistivity Employed At The Livonia Mound Site (16pc1), Pointe Coupee Parish, Louisiana, Jennifer Patricia Gardner Jan 2014

Electrical Resistivity Employed At The Livonia Mound Site (16pc1), Pointe Coupee Parish, Louisiana, Jennifer Patricia Gardner

LSU Master's Theses

Electrical resistivity was used at the Livonia Mound site (16PC1) to identify construction breaks, possible human burials, and other cultural activity below the surface. Resistivity transects traveled across the mound and the level surface directly south of the mound; this latter section was called Area A. Four transects stretched across the north, south, west, and east slopes of the mound; as a result, four vertical profiles were created from the apparent resistivity (ƒâa) values. The standard deviation of each transect was computed using the ƒâa values from the four pseudo-sections to establish the base-line for analysis. ƒâa values for Area …

The Adoption Of State Wetland Policies: How Do Wetlands Fit Within The Theoretical Framework Of Environmental Policy Determinants?, Rachel Bogart Krech Jan 2014

The Adoption Of State Wetland Policies: How Do Wetlands Fit Within The Theoretical Framework Of Environmental Policy Determinants?, Rachel Bogart Krech

LSU Master's Theses

Wetlands are an extremely important natural resource in the United States. They offer storm surge protection, sediment stabilization, groundwater recharging, carbon sequestration, and habitat for many species. Despite their values, wetlands have a long history of being misunderstood. It was not until the mid-1970s that scientific understanding helped transform policy from that of rapid conversion to that of conservation. By this time, the lower 48 states had already lost 53 percent of its total wetlands. The nature of wetlands and federal limitations make the management of this natural resource a primarily state-based responsibility. However, the way that states construct their …

The Spatial-Temporal Prediction Of Various Crime Types In Houston, Tx Based On Hot-Spot Techniques, Shuzhan Fan Jan 2014

The Spatial-Temporal Prediction Of Various Crime Types In Houston, Tx Based On Hot-Spot Techniques, Shuzhan Fan

LSU Master's Theses

A series of hotspot mapping theories and methods have been proposed to predict where and when a crime will happen. Each method has its strengths and weaknesses. In addition, the predictive accuracy of each hotspot method varies depending on the study area, crime type, parameter settings of each method, etc. The predictive accuracy of hotspot methods can be quantified by three measures, which include the hit rate, the predictive accuracy index (PAI), and the recapture rate index (RRI). This thesis research applied eight hotspot mapping techniques from the crime analysis field to predict crime hotspot patterns. In addition, these hotspot …

Danger Shelter Opportunity: The Coastal Fortifications Of Nineteenth Century Louisiana, James F. Osborne, Iv Jan 2014

Danger Shelter Opportunity: The Coastal Fortifications Of Nineteenth Century Louisiana, James F. Osborne, Iv

LSU Master's Theses

This document seeks to establish a contemporary record of the nineteenth-century masonry fortifications of the Third System whose continued existence in Southeastern Louisiana is in peril. Designed and implemented in the years following the invasion of Washington, D.C. during the War of 1812 by Napoleon Bonaparte’s chief engineer, Louisiana’s coastal forts represent the pinnacle of European, pre-modern-warfare military architecture. With their obsolescence secured by advances in technology in the mid to late nineteenth century, each was abandoned or decommissioned following the American Civil War. These historic constructed spaces that are each uniquely adapted to the land they occupy have never …

Animal Scavenging On Human Skeletal Remains In The Southwest United States: A Preliminary Model, Maximilian Hiram Cantu Jan 2014

Animal Scavenging On Human Skeletal Remains In The Southwest United States: A Preliminary Model, Maximilian Hiram Cantu

LSU Master's Theses

Animal scavenging is a major taphonomic process responsible for damage to bone and alternations to postmortem interval estimates. Despite the significant implications animals can have on altering forensics cases, extensive research on animal scavenging has yet to be done. The most notable research on animal scavenging comes from Haglund . Haglund’s extensive research in the Pacific Northwest led him to create a model for the sequence in which animals scavenge and disarticulate a human body after death. The major goal of my research was to apply Haglund’s model to 60 southern Arizona cases in order to see if animals scavenge …

An Analysis Of Osteoarthritis Of The Upper Limbs In The Tchefuncte Site (16st1), Mallory Baldridge Jan 2014

An Analysis Of Osteoarthritis Of The Upper Limbs In The Tchefuncte Site (16st1), Mallory Baldridge

LSU Master's Theses

Osteoarthritis is a degenerative disorder of the synovial joints which is frequently linked to activity and age, as well as numerous other etiologies. In particular, osteoarthritis of the shoulder is often shown to correlate with age, while osteoarthritis of the elbow is often shown to correlate with physical activity. The presence and pattern of osteoarthritis has been investigated in numerous Native American populations, but to date, its presence has not been investigated in the skeletal collection from the Tchefuncte site (16ST1), a Tchula Period shell midden site in St. Tammany Parish, Louisiana. Osteoarthritis of the upper limbs is examined in …

The Feasibility Of Creating A 3d Digital Skeletal Collection For Research Purposes And Museum Use, Karen Leigh Beebe Jan 2014

The Feasibility Of Creating A 3d Digital Skeletal Collection For Research Purposes And Museum Use, Karen Leigh Beebe

LSU Master's Theses

3D scanners offer many advantages to scientists and museum curators, such as a permanent digital archival record of the scanned object, the non-intrusive nature of 3D laser surface scanning, the ability to create and share a digital collection with other researchers, and the portability of recent scanners. With the purpose of determining the feasibility of creating a 3D research collection in mind, I have scanned and studied skeletal material from Wild Cane Cay and Moho Cay, Belize. I explore how the 3D model compares to the physical bone and the significance of 3D imaging to the anthropological community.

Can You Hear The People Sing: Community Theater, Play And The Middle Class, Heather Marie Moats Jan 2014

Can You Hear The People Sing: Community Theater, Play And The Middle Class, Heather Marie Moats

LSU Master's Theses

Over the last century community, or “little”, theaters have popped up all over the United States as a way for amateur actors to perform. Academic research in both anthropology and theater studies have greatly overlooked and dismissed these theaters. Using data collected via ethnographic methods over the course of two musical productions, approximately seven months total, at a community theater in Baton Rouge, Louisiana I hope to demonstrate both why individuals, predominately within the middle class, with limited leisure time choose to spend it volunteering at a community theater as well as some of the social and interpersonal benefits it …

Avian Biogeography And Conservation In Eastern Indonesia, John C. Mittermeier Jan 2014

Avian Biogeography And Conservation In Eastern Indonesia, John C. Mittermeier

LSU Master's Theses

Evaluating the conservation status of threatened species requires a sequential process of 1) taxonomic classification, 2) distributional mapping, and 3) evaluation of species according to criteria established by the IUCN Red List. Knowledge gaps in the first two phases of this process have been termed the Linnaean and Wallacean Shortfalls, respectively. The Indonesian archipelago is one of the most biologically diverse areas of the planet, as well as one of the most threatened and poorly studied, and the Linnaean and Wallacean Shortfalls pose substantial challenges for conservation in the region. Here I address each of the three stages of categorizing …

The Visual Novel: Fictional Space And Print After 1900, Michael James Griffin Ii Jan 2014

The Visual Novel: Fictional Space And Print After 1900, Michael James Griffin Ii

LSU Doctoral Dissertations

My dissertation, The Visual Novel: Fictional Space and Print After 1900, examines how and why the novel has assimilated visual mediums—film, art, and the digital—into the genre as a means of adapting to the proliferation of mass media and technology. This project connects a history of the novel (genre) with a history of the book (the genre’s physical form), thereby theorizing and narrating a history of the visual novel. I demonstrate that through fictional space, a critical term used by narratologists and textual studies scholars, visual writing emerges as a hybridized mode of creative composition where we can see most …

"Post Your Version Here!": Performances In/Of Online, Noncommercial, Video-To-Video Adaptations, Lyndsay Michalik Jan 2014

"Post Your Version Here!": Performances In/Of Online, Noncommercial, Video-To-Video Adaptations, Lyndsay Michalik

LSU Doctoral Dissertations

Processes of creative adaptation no longer fit traditional, culturally sanctioned forms, like commercial book-to-film adaptation, or vice versa. Meanwhile, internet users are demonstrating how noncommercial, creative text adaptation using video technology has become an everyday art form, a skill set, a form of communication, and a means of cultural commentary. Internet video adapters physically perform in their own videos and they create videos that work performatively online. Negotiating the slippery spaces between copyright, creativity, and cultural commentary, these creators adapt videos in myriad ways, and find spaces to share their adaptations online, despite (for most) a lack of financial return …

Adaptive Divergence And Speciation Across Depth In A Caribbean Candelabrum Coral, Carlos Andrés Prada Montoya Jan 2014

Adaptive Divergence And Speciation Across Depth In A Caribbean Candelabrum Coral, Carlos Andrés Prada Montoya

LSU Doctoral Dissertations

Since Darwin, biologists wonder how organisms cope with environmental variation, why there are so many species, and how species form. In my dissertation, I explore how species of long-lived, clonal reef organisms originate across depth gradients. In Chapter 2, I evaluate the strength of depth to isolate populations by comparing the genes and morphologies of pairs of depth-segregated populations of the candelabrum coral Eunicea flexuosa across the Caribbean. Eunicea flexuosa is a long-lived clonal cnidarian that associates with an alga of the genus Symbiodinium. Genetic analysis revealed two depth-segregated lineages, each genetically well-mixed across the Caribbean. Survivorship data, combined with …

Evaluating Alternative Techniques For Forecasting Industrial And Occupational Employment, Drew A. Varnado Jan 2014

Evaluating Alternative Techniques For Forecasting Industrial And Occupational Employment, Drew A. Varnado

LSU Doctoral Dissertations

This paper offers three different regional output-by-industry forecasting techniques (time series, Social Accounting Matrix (SAM)-based, and Computable General Equilibrium (CGE)-based) and two different occupation-by-industry matrices (national and state geographies) for use in the creation of industry/occupation employment forecasts. Estimates are compared to actual data from eight years from 2001 to 2010. OLS regressions are run to determine how well modeled employment estimates fit actual employment for the state of Louisiana. A meta-analysis style regression of the R-sqaured values on model characteristics (accounted for using Boolean dummy-variables) determines that industrial output forecasting techniques do not provide statistically different R-squared values, but …

Chemistry And Application Of Pulses As Value-Added Ingredients In Processed Foods, Darryl Holliday Jan 2014

Chemistry And Application Of Pulses As Value-Added Ingredients In Processed Foods, Darryl Holliday

LSU Doctoral Dissertations

Chemical characterization of pulses allows for varying rates of water absorption, least gelation capacity, and retrogradation depending on species. Nutritionally, pulses are good sources of protein while being low in fat. Pulses deliver a readily bioavailable food form of several key minerals. Additionally, they deliver fiber. The insoluble fiber components are both natural and formed resistant starch in addition to the oligosaccharide content. Therefore, pulses can serve both a nutritional and functional role when used as a value-added ingredient. Meat patties were produced from beef and 23 different pulses at 35%, 42.5%, and 50% ratios. Each patty was tested for …

Mental Mapping The Transformation Of Social Space In Rio's Oldest Favela: Morro Da Providência, Jamie Lauren Worms Jan 2014

Mental Mapping The Transformation Of Social Space In Rio's Oldest Favela: Morro Da Providência, Jamie Lauren Worms

LSU Doctoral Dissertations

Amid the 2014 FIFA World Cup and the 2016 Olympic Games, strategic policy reforms at the federal, state, and municipal levels have reordered and re-purposed the social space of Rio’s favelas through the implementation of social and physical infrastructure. This research project contributes a geographical perspective to the ways in which fast-paced urbanization transforms and produces social space in Rio’s oldest favela, Morro da Providência. Based on Henri Lefebvre’s conceptual triad concerning the production of social space, this research uses mental mapping to understand the disparity between representations of conceived space and representational lived space. It also contributes to perceived …

Holocene Paleoenvironmental Reconstruction From Mexico's Pacific Coast-A Paleotempestological Investigation, Thomas Bianchette Jan 2014

Holocene Paleoenvironmental Reconstruction From Mexico's Pacific Coast-A Paleotempestological Investigation, Thomas Bianchette

LSU Doctoral Dissertations

This dissertation examines the paleoenvironments of four lagoons from Mexico’s Pacific coast, with the aim of retrieving sediment deposition from storm surge events to determine long-term tropical cyclone (TC) records. Lagoons Agua Dulce, Boquita, Mitla, and Nuxco are located along a 700 km stretch in states Jalisco and Guerrero. Roughly 70 meters of sediment were collected and subjected to multiple proxies, including loss-on ignition, a microfossil survey, and geochemical analysis. Nuxco’s dynamism is caused by intense and prolonged rainfall (largely from TCs), responsible for increasing water level, opening the tidal inlet, and draining the site (termed “blowouts”). High amounts of …

Subjugated Territory: The New Afrikan Independence Movement And The Space Of Black Power, Paul Karolczyk Jan 2014

Subjugated Territory: The New Afrikan Independence Movement And The Space Of Black Power, Paul Karolczyk

LSU Doctoral Dissertations

In this dissertation, I study the black revolutionary nationalist geography of the New Afrikan Independence Movement (NAIM) and the anti-racist space of Black Power. I adapt social theorist Henri Lefebvre’s concept of representational space to show how New Afrikan revolutionary nationalism intersects with space, place, and scalar politics in a representational space of black radicalism that confounds dominant notions of race, cultural identity, and national belonging in the United States. NAIM originated in 1968 when several-hundred black nationalist delegates met at the National Black Government conference in Detroit to create the Provisional Government of the Republic of New Afrika. New …

The Worlds Of Agriculture In Asia : Agricultural And Economic Development, Lorna Econg Amrinto Jan 2014

The Worlds Of Agriculture In Asia : Agricultural And Economic Development, Lorna Econg Amrinto

LSU Doctoral Dissertations

The agro-fundamentalists consider agriculture as the engine of growth while agro-pessimists argue that economic growth causes agricultural productivity. It is the main engine of growth in agriculture-based countries; less important in transforming economies; and plays the same role as other tradable sectors in urbanized countries (World Bank, 2008). This work revisits agriculture’s role in the development process within the experience of Asia where the majority of the population heavily depends on agriculture. Chapter 2 presents the results of causality tests between agriculture and economic growth in bivariate systems using the TYDL methodology. For some of agriculture-based Asia (Bhutan, Lao, Cambodia …
