Attitude Toward Companion And Guard Dogs In Hawaii: Health And Welfare Implications, Lynn Morrison, Julie Ann Luiz Adrian, Marina Kelley, Johana Hill, Zachariah Tman, Dana-Lynn Ko'omoa-Lange Oct 2021

Attitude Toward Companion And Guard Dogs In Hawaii: Health And Welfare Implications, Lynn Morrison, Julie Ann Luiz Adrian, Marina Kelley, Johana Hill, Zachariah Tman, Dana-Lynn Ko'omoa-Lange

People and Animals: The International Journal of Research and Practice

The island of Hawaii exhibits extremes in dog welfare ranging from dogs as family members to dogs used as commodities, either as guard or hunting dogs, with many lacking appropriate care. This study offers a preliminary exploration of people’s attitudes toward companion and noncompanion dogs and the health and welfare implications for humans and dogs. Data collection included interviews and surveys conducted among 20 companion dog/human and eight guard dog/human dyads. Blood pressure (BP) was monitored during interviews to assess stress. The results of the interview data led to five themes. The first two themes describing contexts of dog welfare …


Trade-Offs In Growth And Development: A Life History Approach, Anna Medendorp Rautman Oct 2021

Trade-Offs In Growth And Development: A Life History Approach, Anna Medendorp Rautman

Anthropology ETDs

Life history theory (LHT) is the conceptualization of tradeoffs in resources allocation. Plasticity, the ability of phenotypes to vary in response to environmental cues, is integral to LHT. Prior to completed maturation, resources are distributed towards maintenance or somatic maturation, a combination of growth and development (G&D). This dissertation presents an examination of intragroup variation in the G&D of the dental and skeletal systems within a sample of 20th century White females to consider whether they provide evidence for tradeoffs within the subadult interval. In a series of individual research chapters, I consider the following: 1) how does the relative …


Multi-Agent Scavenging Patterns In Hawai‘I: A Forensic Archaeological And Skeletal Case Study, Jennifer F. Byrnes, William Belcher Sep 2021

Multi-Agent Scavenging Patterns In Hawai‘I: A Forensic Archaeological And Skeletal Case Study, Jennifer F. Byrnes, William Belcher

Department of Anthropology: Faculty Publications

Knowledge of the behavior of local fauna can aid forensic investigators in developing awareness of site formation processes. In Hawai‘i, little has been published on the effects of feral domestic pig (Sus scrofa) and feral domestic dog (Canis familiaris) scavenging and bone dispersal on field recovery and laboratory observations. In this Pacific tropical setting, the most consequential terrestrial taphonomic agents are pigs and dogs, both in terms of hard tissue modification and dispersal of remains across the landscape. In 2017, an archaeologist discovered the remains of an unidentified decedent on the island of Kauaʻi, State of Hawai‘i during a cultural …


Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath Aug 2021

Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath

Symposium of Student Scholars

Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating which …


Case 3847 – Simopithecus Oswaldi Andrews, 1916 (Currently Theropithecus Oswaldi; Mammalia, Primates, Cercopithecidae), Proposed Conservation By Reversal Of Precedence With Cynocephalus Atlanticus Thomas, 1884., Eric Delson, David M. Alba, Stephen R. Frost, Dagmawit Abebe Getahun, Christopher C. Gilbert Aug 2021

Case 3847 – Simopithecus Oswaldi Andrews, 1916 (Currently Theropithecus Oswaldi; Mammalia, Primates, Cercopithecidae), Proposed Conservation By Reversal Of Precedence With Cynocephalus Atlanticus Thomas, 1884., Eric Delson, David M. Alba, Stephen R. Frost, Dagmawit Abebe Getahun, Christopher C. Gilbert

Publications and Research

The purpose of this application, under Articles 23.9.3 and 81.1 of the Code, is to conserve the usage of the species-group name Simopithecus oswaldi Andrews, 1916 by giving it precedence over its senior subjective synonym Cynocephalus atlanticus Thomas, 1884. Theropithecus is a common to dominant member of the extinct primate community across Africa after 4 million years ago (Jablonski & Frost, 2010) and often co-occurred with extinct humans (Hominini); fossils are also known rarely across Eurasia (Roberts et al., 2014). Most fossil samples are currently included in Theropithecus oswaldi (Andrews, 1916), which is often divided into chrono-geographic subspecies. Cynocephalus atlanticus …


The Evolution Of Sex Differences In Mandrills (Mandrillus Sphinx): Micro- And Macroevolution, Jerred Klint Schafer Aug 2021

The Evolution Of Sex Differences In Mandrills (Mandrillus Sphinx): Micro- And Macroevolution, Jerred Klint Schafer

Legacy Theses & Dissertations (2009 - 2024)

Primates show diverse patterns of adaptive color and body size dimorphism produced by inter- and intrasexual selection. However, the specific microevolutionary processes that produce variation in secondary sexual characteristics remain largely unexplored in primates. Furthermore, sexual conflict theory predicts that female and male secondary sexual traits can coevolve in an antagonistic manner and promote speciation. This dissertation explores the microevolution of secondary sexual characteristics in mandrills (Mandrillus sphinx) and the macroevolution of these characters in anthropoid primates. I address the microevolution of mandrill facial coloration and body mass by estimating the heritability, phenotypic selection, and genetic evolution of these traits …


The Shortcomings Of Maize: Using Tipu To Assess Maize Consumption And Its Impact On Stature And Limb Proportions Among The Maya, Peter Mercier Aug 2021

The Shortcomings Of Maize: Using Tipu To Assess Maize Consumption And Its Impact On Stature And Limb Proportions Among The Maya, Peter Mercier

Master's Theses

A reliance on maize among the ancient and modern Maya has been reasoned to cause short statures and short legs compared to overall height. The goal of this study was to test this proposition using a sample of contact period Maya from the site of Tipu in western Belize. Long bone length data from 100 individuals were compared to that from two other prehistoric maize agriculturalist societies: the Schild site in Illinois and Pecos Pueblo in New Mexico.

Four hypotheses were tested: 1) Tipu would be the shortest, 2) Tipu would have the shortest femora relative to tibiae, 3) Tipu …


Analyzing The Consistency Of Scoring Porotic Hyperostosis From 3d Scans, Carson Rouse Aug 2021

Analyzing The Consistency Of Scoring Porotic Hyperostosis From 3d Scans, Carson Rouse

Master's Theses

The use of 3D scans is becoming more and more common in the field of bioarchaeology. They alleviate the need to travel, allow for larger sample sizes, and can help preserve bones with pathologies on them which make them more fragile. Though there are major benefits with using 3D scanning of human remains, there is a lack of studies which examine whether or not traditional pathology scoring methods can be used to consistently gather the same data from these 3D scans. This project examines how consistently six researchers of varying experience levels scored porotic hyperostosis from 25 3D scans on …


Subadult Cortical Bone Analysis As An Indicator Of Childhood Health Status Among The Tipu Maya Population, Jaime Thomas Aug 2021

Subadult Cortical Bone Analysis As An Indicator Of Childhood Health Status Among The Tipu Maya Population, Jaime Thomas

Master's Theses

This thesis explores juvenile health at the contact Maya site of Tipu in western Belize. The associated cemetery was excavated and provided a large and well-preserved population. Although Tipu has been a focus of many studies, few studies have focused on subadults and none on their cortical development, which can allow insight into access to necessary nutritional resources.

Some 108 femora belonging to individuals aged birth to 13 years with femora previously sectioned at midshaft provided the sample. External dimensions taken included diaphyseal length, circumference, medial-lateral diameter and anterior-posterior diameter. Additionally, cortical thickness was measured at four points, and 95 …


"When The Voices Of Children Are Heard": Evaluating The Biological Effects Of Socioeconomic Status On Children In Postmedieval London., Ashley R. Ezzo Aug 2021

"When The Voices Of Children Are Heard": Evaluating The Biological Effects Of Socioeconomic Status On Children In Postmedieval London., Ashley R. Ezzo

Electronic Theses and Dissertations

As the most vulnerable members of society, children (and their treatment) may reveal important sociocultural and socioeconomic praxes throughout human history. During the Postmedieval period, children, especially low socioeconomic status (SES) individuals, participated in the workforce. By examining the demographic distributions and paleopathological profiles of juvenile skeletal remains from high SES (St. Bride’s Crypt and Chelsea Old Church) and low SES (St. Bride’s Lower and Crossbones) Postmedieval (1700-1850 CE) London cemeteries, we can better understand how SES impacted the biological health and mortality of children. While results indicated higher mortality risk associated with low SES circumstances, most differences in pathological …


Determining Dietary Niche In Primates Using Portable X-Ray Fluorescence, Theresa C. Schwartz Jul 2021

Determining Dietary Niche In Primates Using Portable X-Ray Fluorescence, Theresa C. Schwartz

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Diet is a critical component of the ecology of an animal. Many dietary reconstructions involve destruction of the sample. Portable X-Ray fluorescence (pXRF), however, is a non-destructive method of gathering elemental data. This is important for research in biological anthropology and diet reconstructions because it leaves a sample intact of which there might only be few specimens. There has been a gap in dietary reconstructions using non-destructive methods like pXRF which is portable, cheaper, and as accurate as destructive methods and should therefore be implemented into research of this nature. This research attempts to validate this method by determining dietary …


Dataset For Faunal Analyses Of Biry House Food Remains, Castroville, Tx, Kathryn Maupin Jun 2021

Dataset For Faunal Analyses Of Biry House Food Remains, Castroville, Tx, Kathryn Maupin

Anthropology Datasets

In 2013, Van Dyke excavated a historic residence located at 309th Paris Street in Castroville, Texas. Beginning in 1844, the house was occupied by the families that had immigrated from the Alsace region of France. Preliminary analyses of the faunal recovered from a lime slaking pit suggested that over the course of the home’s residence, family members incorporate wild taxa into their diet in addition to their traditional Alsatian foodstuffs. Expanded analyses of the faunal remains from additional features provide additional evidence that the diet of the residents slowly transitioned away from a strict Alsatian diet and eventually included …


Patterns Of Recent Natural Selection On Genetic Loci Associated With Sexually Differentiated Human Body Size And Shape Phenotypes, Audrey M. Arner, Kathleen E. Grogan, Mark Grabowski, Hugo Reyes-Centeno, George H. Perry Jun 2021

Patterns Of Recent Natural Selection On Genetic Loci Associated With Sexually Differentiated Human Body Size And Shape Phenotypes, Audrey M. Arner, Kathleen E. Grogan, Mark Grabowski, Hugo Reyes-Centeno, George H. Perry

Anthropology Faculty Publications

Levels of sex differences for human body size and shape phenotypes are hypothesized to have adaptively reduced following the agricultural transition as part of an evolutionary response to relatively more equal divisions of labor and new technology adoption. In this study, we tested this hypothesis by studying genetic variants associated with five sexually differentiated human phenotypes: height, body mass, hip circumference, body fat percentage, and waist circumference. We first analyzed genome-wide association (GWAS) results for UK Biobank individuals (~194,000 females and ~167,000 males) to identify a total of 114,199 single nucleotide polymorphisms (SNPs) significantly associated with at least one of …


Language As The Medium: A Literature Review. Harnessing The Prolific Power Of Dramatic Language As A Therapeutic Tool In Drama Therapy, Edward Freeman May 2021

Language As The Medium: A Literature Review. Harnessing The Prolific Power Of Dramatic Language As A Therapeutic Tool In Drama Therapy, Edward Freeman

Expressive Therapies Capstone Theses

Language in and of the theatre, with its palate of variegated writing styles and playwrights from throughout time, has the potential to be harnessed, focused, and systematized for use as a therapeutic tool within drama therapy – the field’s artistic medium. Drama therapy could benefit from having a specific medium germane to its artform which has the potential to provide practitioners with a common resource and means of communication, assessment, diagnosis, and treatment planning, as well as align the field with other creative arts therapies. Language encompasses all forms of human communication – speaking, writing, signing, gesturing, expressing facially – …


Reiki For Recovery: Incorporating Japanese Health Practices To Increase Contemporary Resiliency In American Health, Leif Peterson May 2021

Reiki For Recovery: Incorporating Japanese Health Practices To Increase Contemporary Resiliency In American Health, Leif Peterson

Master's Projects and Capstones

The Japanese health practice of Reiki attempts to maximize the latent ability of the human system to heal itself. The Reiki system, established over a century ago, combines multiple Asian health traditions, experimenting with practices that maximize the natural processes of the body to perform its own repairs. Reiki encourages healthy behaviors that balance the mind and body, return the human system to a lowered stress level, and allow for an optimal recovery state for the patient. This paper illustrates how this Japanese health-affirming method can be integrated and utilized within existing health and medical practices. An area that is …


Detecting Bacterial Species From Ancient Human Skeletal Samples, Ariel Owens, Daisy Mcgrath, Tsai-Tien Tseng May 2021

Detecting Bacterial Species From Ancient Human Skeletal Samples, Ariel Owens, Daisy Mcgrath, Tsai-Tien Tseng

Symposium of Student Scholars

This paleopathological study aims to identify Mycobacterium tuberculosis complex (MTBC), Mycobacterium avium complex (MAC) and other Mycobacterium species in silico from skeletal samples that belonged to 28 Polish individuals in the Neolithic period under PRJNA422903 from the Sequence Read Archive (SRA). After next-generation sequencing (NGS), bioinformatics methods are heavily relied upon for identification of pathogens from complex samples. We implemented a bioinformatics pipeline, with custom-built databases, utilizing the following software tools: Trim Galore! and Kraken2. After adapter trimming, Kraken2 was used for taxonomic classifications. We have found that Mycobacterium is present in all 28 individuals. The average percentage of MAC …

The Rates Of Caries Prevalence By Sex And Age From Individuals In St. Mary Graces And East Smithfield Cemeteries, Elizabeth Houston, Joseph Upton May 2021

The Rates Of Caries Prevalence By Sex And Age From Individuals In St. Mary Graces And East Smithfield Cemeteries, Elizabeth Houston, Joseph Upton

Honors Theses

Caries are a common pathology in past and current populations, and because of the close interaction of dentition with diet, archaeologists are able to infer components of a population’s culture from pathology like caries (Lanfranco & Eggers, 2010). Most literature implies that women have higher rates of caries than men because of cultural practices and natural physiological differences which are thought to put women at an increased risk (Lukacs, 2008). Another established trend throughout literature is that caries prevalence tends to increase with age, regardless of sex (Hillson, 2008). We evaluated data from the East Smithfield (1348-1350 AD) and Saint …


Intergenerational Embodiment Of Stress : How The Broader Sociocultural Environment Can Shape Child Growth And Development, Elizabeth A. Holdsworth May 2021

Intergenerational Embodiment Of Stress : How The Broader Sociocultural Environment Can Shape Child Growth And Development, Elizabeth A. Holdsworth

Legacy Theses & Dissertations (2009 - 2024)

Childhood growth has been a means of identifying systemic, material inequalities within populations. The plasticity of growth is responsive to multiple environmental factors, most notably adequate nutrition, but also psychosocial stress. Psychosocial stress can be a function of the social and political economic ecology, reinforcing power hierarchies within societies. This dissertation proposes that childhood growth can also reflect inequality in the distribution of psychosocial stress exposure through mothers’ feelings of a chronically stressful environment conveyed through maternal-infant interactions.


Covid-19’S Impact Of Social Isolation On Seniors In An Assisted Living Facility, Mary Mclaughlin May 2021

Covid-19’S Impact Of Social Isolation On Seniors In An Assisted Living Facility, Mary Mclaughlin

Theses/Capstones/Creative Projects

This study explores the impact of social distancing precautions in response to the rapidly evolving COVID-19 pandemic by resident seniors in an assisted living facility. Previous studies describe how social distancing regulations can amplify feelings of loneliness in all age groups. However, pandemic-related lockdowns and social distancing measures disproportionately affect vulnerable older populations. Resident seniors in an assisted living facility in Omaha, NE participated in a semi-structured interview focused on the perceived impact of COVID-19 safety precautions. Participants reported a temporal dimension of impact, specifically, an increased level of loneliness in the evening, but also discussed the importance of encouragement …


An Evaluation Of Activity In A Colonial Maya Cemetery Using Femoral Cross-Sectional Analysis, Casey Lejeune May 2021

An Evaluation Of Activity In A Colonial Maya Cemetery Using Femoral Cross-Sectional Analysis, Casey Lejeune

Master's Theses

Cortical bone formation in the population of Tipu, a colonial visita site in Belize, was examined here to reveal factors of their activity and address the possibility of a status-based burial plan. To answer this question, this research examined the endosteal surface of the midshaft femur using digital imaging methods. The femora from 70 individuals were photographed and examined using the BoneJ plugin in ImageJ software. The cortical bone area was compared to additional variables, including sex, age, stature, pilastric index, and burial location. It was hypothesized that sex, age, and stature would correlate with cortical bone area similarly across …


A 3-Dimensional Approach To Projectile Point Classification, Kayden Dennis May 2021

A 3-Dimensional Approach To Projectile Point Classification, Kayden Dennis

Graduate Theses and Dissertations

Typologies have long been used by archaeologists to answer questions about the past, ranging from issues of site chronology to tool function. However, current methods are hampered by subjective misclassifications as well as a loss of the range of variability among different tool forms due to a process that forces them into singular types. This thesis looks to create a simple and reliable technique of projectile point classification. It is also the author’s goal to use a classification system that monitors cultural transmission over time. This objective is addressed with an Archaic projectile point sequence from the Albertson site in …


The Role Of Culture In Sustainable Communities: The Case Of Rapa Nui (Easter Island, Chile), Pamela A. Mischen, Carl P. Lipo Apr 2021

The Role Of Culture In Sustainable Communities: The Case Of Rapa Nui (Easter Island, Chile), Pamela A. Mischen, Carl P. Lipo

Anthropology Datasets

We explore how the combination of cultural heritage and present-day cultural affili- ations influences the construction of the concept of sustainability at the scale of the community using the case study of Rapa Nui (Easter Island, Chile). We argue that overlapping affiliations—expressed through administrative culture, organizational culture, and professional culture—influence the views held by governance leaders. Furthermore, the role of cultural heritage must be considered in efforts to change and perpetuate sustainability-related behaviors within a community. Using archeo- logical and historical evidence from the pre-contact and historical record of Rapa Nui, we discuss how cultural heritage evolved endogenously in response …


The Genetic Links Between Archaic And Modern Humans, Maria J. Orellana Rosales Apr 2021

The Genetic Links Between Archaic And Modern Humans, Maria J. Orellana Rosales

Thinking Matters Symposium

Our modern physiology is the mixture of many archaic humans that once roamed our planet. The evidence of these archaic humans is still present in our DNA. This poster reviews how our understanding of ancient human genetics has drastically changed due to advances in molecular genetics. Neanderthal and Denisovan remains have been sequenced for nuclear and mitochondrial DNA. Neanderthal and Denisovan genetic ancestry have been identified by genomic studies in modern human populations across Eurasia and Pacific Island regions. Studies have shown a gene flow of 4±1% from Neanderthals to present-day Eurasians. Whereas, Papuan and Melanesian individuals share 4±0.7% more …


Embodied Injustices: Covid-19, Race, And Epigenetics, Maria Encinosa Apr 2021

Embodied Injustices: Covid-19, Race, And Epigenetics, Maria Encinosa

Showcase of Osprey Advancements in Research and Scholarship (SOARS)

Digital Projects Showcase Exhibitor Award Although historical and even modern accounts of race assume significant biological differences between racial groups, race has little biological meaning. Nonetheless, the social construct of race has real consequences. Racial identity defines boundaries of community and impacts the experiences of individuals, including how people live and die during a pandemic. COVID-19 has disproportionately affected minority communities in the United States, triggering many explanations for racial disparities in health. Through an analysis of sources spanning from popular media to traditional academic journals, I analyze the potential for epigenetic research to serve as a missing link that …

By examining this data, I will be able to answer …


"The Face Of The Agency": Interviews With Death Investigators In South Louisiana, Natalie H. King Mar 2021

"The Face Of The Agency": Interviews With Death Investigators In South Louisiana, Natalie H. King

LSU Master's Theses

According to the American Board of Medicolegal Death Investigators, “the role of the medicolegal death investigator is to investigate any death that falls under the jurisdiction of the medical examiner or coroner, including all suspicious, violent, unexplained and unexpected deaths” (American Board of Medicolegal Death Investigators [ABMDI], n.d.). As such, a death investigator has a job that is highly intense and stressful at a level similar to that of doctors, nurses, emergency medical technicians (EMTs), and firefighters. The majority of the literature written about death investigators focuses on procedural issues, while there seemingly is a lack of literature focused on …


The Bioarchaeology Of The Lake St. Agnes Mound (16av26) Site: Exploring Diet From Fragmentary Remains, Kenneth Tremblay Mar 2021

The Bioarchaeology Of The Lake St. Agnes Mound (16av26) Site: Exploring Diet From Fragmentary Remains, Kenneth Tremblay

LSU Master's Theses

The Lake St. Agnes Mound (16AV26) site, located in central Louisiana, is composed of two, temporally distinct burial components; one, a Coles Creek period component, at the base of the mound (~780-880 CE), and the other, a Plaquemine subperiod component, at its apex (~1400 CE). These burials, though heavily fragmented, commingled, and representing small sample sizes, are valuable for studying the transition to agriculture in the Lower Mississippi River Valley. It is now clear that for the Coles Creek period, maize was likely only a ceremonial crop rather than a staple food source (Kidder, 1993; Listi, 2011). The reliance on …


Assessing The Validity Of The Estimation Of Population Affinity From The Maxillary Hard Palate: An Empirical Approach Using A Modern Forensic Sample, Christopher M. Goden Mar 2021

Assessing The Validity Of The Estimation Of Population Affinity From The Maxillary Hard Palate: An Empirical Approach Using A Modern Forensic Sample, Christopher M. Goden

LSU Master's Theses

In response to Beathard and DiGangi’s (2020) call to action for empirical assessment of population affinity estimation methodology, this study investigates the validity of maxillary palate shape as an indicator of ancestral population affinity for human skeletal remains through the use of Elliptical Fourier Analysis (EFA) and Linear Discriminant Function Analysis (DFA). Further, this study also places emphasis on the expressed variation of palate shape within and between population groups exemplified by Principal Component Analysis (PCA) of EFA data.

Computed tomography scans of 180 individuals of Black, White, and Hispanic population affinities were obtained from the New Mexico Decedent Imaging …


Using The Seventh Rib Length And Depth Measurements As A Method To Estimate Ancestry And Sex In Adults, Alexandria M. Amaki Mar 2021

Using The Seventh Rib Length And Depth Measurements As A Method To Estimate Ancestry And Sex In Adults, Alexandria M. Amaki

LSU Master's Theses

This study tested the correlation of dimensions of the left seventh rib (L7) to ancestry and sex in adult humans. The first hypothesis, based on Bergmann’s theory, is that Black (African-American) individuals will have smaller L7 dimensions than White individuals (Americans of primarily European descent). The second hypothesis is that males, due to sexual dimorphism, will have larger ribs than females. 299 individuals from the Hamann-Todd Skeletal Collection were used in the study, approximately evenly distributed among sex and ancestry groups. Five variables were examined, including three measurements (length, width, and width point), and two calculations (area and ratio). A …
