Resistance Training Versus Cardiovascular Training: Which Is Better For Fat Loss?: A Brief Narrative Review., Jason M. Curtis, Jose Antonio, Cassandra Evans Jan 2025

Resistance Training Versus Cardiovascular Training: Which Is Better For Fat Loss?: A Brief Narrative Review., Jason M. Curtis, Jose Antonio, Cassandra Evans

Journal for Sports Neuroscience

Abstract

Introduction: Obesity has risen from 30.5% to 41.9% from 2000-2017. Those who are considered severely obese increased from 4.7% to 9.2% over that same period. There are numerous fitness-center approaches to induce weight-loss or reduction of body fat. These interventions are often categorized into two general categories: Resistance training (using weighted resistance in anaerobic strength training) and cardiovascular training (aerobic training). While both fitness groups have been shown to be effective, there is a debate about which method is most effective for eliciting changes in body composition, primarily fat loss.

Methods: Google Scholar and Pubmed were scoured for …


Early Bronze Age Fauna From Tel Lod, Edward F. Maher Maher Jan 2025

Early Bronze Age Fauna From Tel Lod, Edward F. Maher Maher

'Atiqot

The excavations at Tel Lod yielded a small zooarchaeological assemblage, primarily dating to Early Bronze Age IB (Strata VII–IV); the material from the latest occupation (Strata III–II) dates to late EB IB or the EB IB/EB II transition. The fauna of both phases is dominated by domestic stock, comprising sheep, goats, cattle and pigs, which were used both for primary products, such as meat, and secondary products, such as dairy, wool, hair, traction and for breeding. Wild animals, such as boar, gazelle, deer and hare, were also occasionally exploited.


Early Bronze Age Remains At Tel Lod, Amir Golani Jan 2025

Early Bronze Age Remains At Tel Lod, Amir Golani

'Atiqot

A rescue excavation conducted in the southwestern part of the Early Bronze Age mound at Lod exposed an intensive settlement. The architectural remains of Strata VI–IV demonstrate the use of rounded exterior corners for domestic structures, characteristic of the end of EB I and the transition into EB II. The architectural remains associated with Strata IV–III include large, possibly public buildings dating to the end of EB IB. The ceramic assemblages from Strata VII–II are typical of late EB I in central and southern Israel. Two Carbon-14 dates from Stratum IV indicate a date at the beginning of EB IB …


Early Bronze Age Ia Settlement Remains At Ḥorbat Ḥammim (South), Near Modi‘In, Edwin C.M. Van Den Brink, Liora Kolska Horwitz, Ofer Marder, Henk K. Mienis Jan 2025

Early Bronze Age Ia Settlement Remains At Ḥorbat Ḥammim (South), Near Modi‘In, Edwin C.M. Van Den Brink, Liora Kolska Horwitz, Ofer Marder, Henk K. Mienis

'Atiqot

The excavation at Ḥorbat Ḥammim (South) yielded a rock-cut basin and a small cave within a limestone bedrock outcrop. The basin is similar to other rock-cut installations previously exposed in the area and dated to the Chalcolithic period.
The manmade rock-cut cave was entered through a shaft. The sediments from the shaft and the cave consisted of many potsherds, stone tools and animal bones, that may have been washed into the cave, or intentionally discarded in it. The cave may have been quarried as early as the Late Chalcolithic period, although the bulk of the pottery dates to EB IA, …


A Ceramic Zoomorphic Figurine From Tel Bet Yeraḥ, Nadeshda B. Knudsen Jan 2025

A Ceramic Zoomorphic Figurine From Tel Bet Yeraḥ, Nadeshda B. Knudsen

'Atiqot

A well-made ceramic zoomorphic figurine was recovered from a domestic EB IB context (Stratum V) in the southern part of Tel Bet Yeraḥ. The physical characteristics of this figurine suggest that it was intended to represent an equid, possibly a donkey. Such animal figurines are common at Early Bronze Age sites, usually representing familiar domesticate animals. The purpose of these figurines remains obscure, with multiple suggestions offered, including their use as toys, talismans, teaching aids, exchange tokens, or for rituals.


Early Bronze Age Remains In The Southern Part Of Tel Bet Yeraḥ, Amir Golani Jan 2025

Early Bronze Age Remains In The Southern Part Of Tel Bet Yeraḥ, Amir Golani

'Atiqot

Five strata were exposed during a salvage excavation near the southwestern fringes of Tel Bet Yeraḥ: late EB I (Stratum V), EB II (Stratum IV) and EB III (Strata III–I). The direct superposition of the strata suggests a minimal time interval between the occupations and a nearly continuous habitation. The architectural remains attest that this area was domestic in nature, a conclusion further supported by the small finds, which include a large quantity of holemouth vessels, probably used as cooking pots, fauna, flint, ground stones and mollusks. This part of the site appears to have been finally abandoned in EB …


The Relationship Between Lower-Body Flexibility And Running Performance In A Half Marathon Downhill Running Event, Logan Petty, Marcus M. Lawrence Jan 2025

The Relationship Between Lower-Body Flexibility And Running Performance In A Half Marathon Downhill Running Event, Logan Petty, Marcus M. Lawrence

International Journal of Exercise Science

International Journal of Exercise Science 18(3): 1-12, 2025. Although previous studies examining treadmill or relatively flat overground running events have found relationships for running performance and flexibility, no study has examined these outcomes during downhill events, including between sexes. Therefore, the purpose of this study was to determine if a relationship exists between lower body flexibility and running performance in recreational adult male and female distance runners competing in a downhill half marathon race. Recreational (n=11 male, n=19 female) adult distance runners completed this study. On the day prior to the race, participants performed a standardized warm-up, …

Biocultural Mobility: The Impact Of Osteoarthritis On Rural Kentuckians, Alexandria Anderson

Mahurin Honors College Capstone Experience/Thesis Projects

Osteoarthritis (OA) is a common chronic degenerative joint disease that results in joint pain and loss of joint function, and it is rising in prevalence alongside an aging population. OA has a complex etiology, with various biological, mechanical, and sociocultural factors affecting its acquisition and progression. Like most diseases, OA has a differential prevalence among populations; it is disproportionally more common in underserved communities, including rural areas. This thesis presents (1) a study comparing selected OA treatment type and patient travel time, (2) a study comparing OA comorbidity amount and rurality, and (3) a discussion of exploratory interdisciplinary methods in …


René Dubos: An Annotated Bibliography, Carol L. Moberg Jan 2025

René Dubos: An Annotated Bibliography, Carol L. Moberg

René Dubos: An Annotated Bibliography

René Dubos (1901–1982), a prominent 20th century scientist, humanist, and philosopher, was a prolific author. Affiliated for more than 50 years with The Rockefeller Institute for Medical Research/The Rockefeller University, his studies ranged from antibiotics and the role of bacteria in human diseases to formulating broad ecological and environmental questions affecting human health and disease. His seminal writings explore a lifelong belief that a living organism—whether microbe, human being, society, or the Earth itself—could be understood only through its relationships with everything else.

This comprehensive bibliography of more than a thousand works by René Dubos includes brief annotations for each …

Fire History, Ecological History, And Historical Human-Environment Interactions In The Northern Great Plains, James Victor Benes Jan 2025

Fire History, Ecological History, And Historical Human-Environment Interactions In The Northern Great Plains, James Victor Benes

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation explores the spatiotemporal signatures of fire in North American grassland ecosystems. In three chapters, I explore different aspects of fire history in the northern Great Plains. Chapter 1 is an introduction. Chapter 2 focuses on the Euro-American Settlement Period (ca. 1850–1950 C.E.). Fire histories from six different lakes in the Nebraska Sandhills are compared with two periods of historic drought and the establishment of United States Post Offices. Five of the six records show increased levels of biomass burning during the initial phases of Euro-American Settlement. Chapter 3 is a long-term (ca. 15,000 years), high-resolution fire history and …


The Cognition Of Emotion: How Cognitive Control And Working Memory Underly Emotion Regulation Strategy Differences, Nathan Chabin Jan 2025

The Cognition Of Emotion: How Cognitive Control And Working Memory Underly Emotion Regulation Strategy Differences, Nathan Chabin

Pitzer Senior Theses

Working memory is crucial for comprehensively grasping the dynamics of emotion regulation (ER) and cognitive control, as it serves as a foundational cognitive resource that influences how individuals manage their thoughts, emotions, and behaviors. This research aimed to examine the role working memory capacity (WMC) has on Frontal Midline Theta (FMT), an EEG marker for cognitive control, during two common ER strategies: emotional suppression and cognitive reappraisal. Participants performed both an Operation Span working memory task and an ER task, where they viewed a series of negative and neutral images across three conditions. First, participants were instructed to passively view, …


Investigating Dimensions Of Social Vulnerability To Wildfire: A Case Study Of Western Montana, Ella Brodowski Jan 2025

Investigating Dimensions Of Social Vulnerability To Wildfire: A Case Study Of Western Montana, Ella Brodowski

Dissertations, Master's Theses and Master's Reports

Communities across the US are facing increased wildfire risks due in part to historic fire suppression efforts, a warming climate, and an influx of people residing in wildland urban interface (WUI) landscapes. Because of these increasing risks, there have been growing concerns about the social factors that can increase individual and community vulnerability to wildfires. This research adds to the discussion of social vulnerability by examining how people living in a geographic area with heightened wildfire risk think about the ways in which people can be more or less vulnerable to wildfires. Using semi-structured interviews, round table discussions, and field …


Relict Ponderosa Pine Mortality And Fuels Study In The Bob Marshall Wilderness, Montana, Usa, Laura K. Schimmel Jan 2025

Relict Ponderosa Pine Mortality And Fuels Study In The Bob Marshall Wilderness, Montana, Usa, Laura K. Schimmel

Dissertations, Master's Theses and Master's Reports

Many forests have historically experienced mixed-severity fire regimes that were disrupted during the 20th century due to fire exclusion policy. A stand of relict Pinus ponderosa in the Bob Marshall Wilderness Complex that burned in 2003, 2011, and 2018 provides a unique case study for investigating the effects of returned fire to the landscape. Many of the trees have fire scars or Indigenous bark-peeling scars, preserving valuable ecological and anthropological history. We sought to determine whether scarred trees were more susceptible to fire damage, if larger trees had greater fire resilience than smaller trees, and if fuel loads have changed …

To wrap-up the lesson, students will pair up, then reflect on their model and then individually write or draw their takeaways.


Trait-Based Predictors Of Social Rank In Astatotilapia Burtoni, Joshua T. Johnson Jan 2025

Trait-Based Predictors Of Social Rank In Astatotilapia Burtoni, Joshua T. Johnson

All Master's Theses

Dominance hierarchies are a central feature of social species, influencing access to resources, reproductive opportunities, and survival. In many animals, body size is a primary determinant of social rank, but other morphological traits may also contribute. This study investigates how physiological traits—including body size, pigmentation, lachrymal striping, and egg spots—relate to social dominance in Astatotilapia burtoni, a socially dynamic African cichlid.

Side-profile photographs were used to measure body size, red, green, and blue pigmentation intensity, lachrymal stripe area, and egg spot count. Behavioral interactions were recorded and analyzed using the Elo rating system to generate a continuous measure of …


“Fixing” Settler Capitalism: Un/Sustainability In The Former Fort Ord, Clare M. Beer, Sara Salazar Hughes Jan 2025

“Fixing” Settler Capitalism: Un/Sustainability In The Former Fort Ord, Clare M. Beer, Sara Salazar Hughes

Urban and Environmental Studies Faculty Works

California's former Fort Ord Army Base is located on the unceded Indigenous territory of the Ohlone Costanoan Esselen Nation. After seven decades as a training ground for foreign wars, the decommissioning of the base triggered an economic, demographic, and cultural crisis for greater Monterey. The solution to this crisis, the Fort Ord Base Reuse Plan, promised sustainable development in the form of local environmental protection, public higher education, and economic growth. We argue that the Fort Ord Base Reuse Plan illustrates a settler sustainability fix, which the state deploys to secure settler capitalist futurity on the Monterey Peninsula at the …


Ecological Interactions Of Large Mammals In Luangwa, Zambia, Jahzara Osborne, Amelia Villaseñor Jan 2025

Ecological Interactions Of Large Mammals In Luangwa, Zambia, Jahzara Osborne, Amelia Villaseñor

2025 Research Poster Competition

"The connection between mammalian behavior in national parks and human-driven environmental change is tenuous. National parks are often considered the last vestiges of natural space, yet they are created and maintained by humans. South Luangwa National Park (SLNP) within the southern East African Rift is a microcosm of this global conundrum and is also a region where stable isotope data is sparce. Understanding the mammalian diets of mammals in the SLNP via carbon and oxygen stable isotopes in teeth will provide a means of understanding variation in one aspect of mammal behavior that may be affected by changing animal-human relationships. …


Comparative Semiotic Analysis Of Non-Verbal Communication: Apis Mellifera Waggle Dance And Human Kinesic Signaling Systems, Nishtha Tikalal Jan 2025

Comparative Semiotic Analysis Of Non-Verbal Communication: Apis Mellifera Waggle Dance And Human Kinesic Signaling Systems, Nishtha Tikalal

Honors Undergraduate Theses

There are many parallels between two seemingly disparate forms of non-verbal communication: the waggle dance of Apis mellifera (honeybees) and human kinesic signaling systems. Through a comparative semiotic analysis, this research aims to conduct a comparative semiotic analysis, investigating structural and functional similarities between these communication methods, challenging anthropocentric assumptions about meaning making in the natural world. This research employs a meta-synthesis approach, drawn from a methodological literature review to examine historical representations of bee-human relationships, semiotics of non-verbal communication, and the specific mechanisms of the waggle dance and human kinesics. This methodology involves systematic categorization and analysis of extracted …


Archaeoparasitology Of The Colorado Plateau, Karl J. Reinhard, Morgana Caacho Jan 2025

Archaeoparasitology Of The Colorado Plateau, Karl J. Reinhard, Morgana Caacho

Karl Reinhard Publications

Archaeoparasitology has been conducted in the Southwest for 57 years. In the first decade of the period, two pictures of parasitism emerged. Analysis of compressed organic sediments from a latrine at Elden Pueblo presented a spectrum of geohelminths not different from medieval Europe. These findings contrast pronouncedly with an analysis of coprolites from all other studies that show consistent pinworm parasitism at other sites in the Southwest. We summarize the paleoepidemiological bases for these contrasting phenomena.

Fecal Glucocorticoid Metabolite And T3 Profiles Of Orphaned Elephants Differ From Non-Orphaned Elephants In Zambia, Daniella E Chusyd, Janine L Brown, Steve Paris, Nicole Boisseau, Webster Mwaanga, Moses Kasongo, Lisa Olivier, Stephanie L Dickinson, Bailey Ortyl, Tessa Steiniche, Steven N Austad, David B Allison, Michael D Wasserman

Children’s Nutrition Research Center Staff Publications

Background: Elephants provide valuable insight into how early-life adverse events (ELAEs) associate with animal health and welfare because they can live to advanced ages, display extensive cognitive and memory capabilities, and rely heavily on social bonds. Although it is known that African savanna elephants that experienced ELAEs, such as being orphaned due to human activities, have altered behavioral outcomes, little is known regarding the physiological consequences associated with those stressors.

Methods: We compared fecal glucocorticoid (fGCM) and thyroid (fT3) metabolites as well as body condition scores (BCS) in rescued and rehabilitated orphaned (early-dry season: n = 20; late-dry season: n …


Nature, Nurture, And Serial Murder: A Biocriminological Analysis Of Jeffrey Dahmer And Aileen Wuornos, Dori W. Jal Jan 2025

Nature, Nurture, And Serial Murder: A Biocriminological Analysis Of Jeffrey Dahmer And Aileen Wuornos, Dori W. Jal

Honors Thesis

In recent years, there has been an increase in public fascination with serial killers, however current criminological explanations continue to focus on social and psychological factors, lacking commentary on potential biological implications. This thesis addresses a gap in the literature by examining how biological processes, specifically epigenetic, neurobiological, and endocrinological mechanisms, interact with environmental stressors to shape serial homicidal behavior. The goal is to determine whether serial murder can be more effectively understood through a biosocial framework that integrates biological vulnerability with lived experience, rather than relying on singular explanatory models.

Using a qualitative multiple-case study methodology, this research analyzes …
