Rosegate Projectile Points In The Fremont Region, James R. Allison, Robert J. Bischoff

Faculty Publications

The Fremont projectile point typology was developed in the 1980s. An early revision combined the Rose Spring Corner-notched and Eastgate Expanding-stem types into a combined Rosegate type with an end date of AD 900-1000. Some archaeologists recognize that these projectile points persist to approximately AD 1300 but others use the earlier date range, and much of the relevant information is confined to gray literature. Furthermore, there is a varied approach to these types. Some use the original two types, while others use Rosegate or a combination of Rosegate, Rose Spring, and Eastgate. We used projectile point typology data, illustrations, and …

Historical And Archaeological Evidence For Flooding In West Provo, Utah, Michael T. Searcy

Faculty Publications

Utah Lake in Utah County, Utah, has been a wealth of resources for generations of people over thousands of years. The lake’s waters also have regularly breached its banks and adversely affected the lives of many people. Using both historical and archaeological data, I provide evidence for successive flooding events that are likely to persist into the future. This same information is used to suggest that Provo City is making poor decisions in their current development of this area next to the lake.

Variations In Paint On San Juan Red Ware, James R. Allison, Aspen Greaves

Faculty Publications

Portable x-ray fluorescence (PXRF) analysis allows rapid, non-destructive characterization of the elements present in paints on archaeological ceramics. By measuring painted and unpainted portions of San Juan Red Ware sherds s from southeastern Utah, we document variation in the elements in the paint. Iron is ubiquitous in San Juan Red Ware paints, while manganese, lead, and copper, were also sometimes present. Manganese is consistently present in black paints on later San Juan Red Wares, and is a useful tool in identifying sherds. Abajo Red-on-orange sherds discolored by exposure to fire can appear to be Bluff black-on-red, but lack manganese. Lead …

Pre-Columbian Rock Mulching As A Strategy For Modern Agave Cultivation In Arid Marginal Lands, Hector Ortiz-Cano, Jose Antonio Hernandez-Herrera, Neil C. Hansen, Steven L. Petersen, Michael T. Searcy, Ricardo Mata-Gonzalez, Teodoro Cervantes-Mendivil, Antonio Villanueva-Morales, Pil Man Park, J. Ryan Stewart

Faculty Publications

Cultivation of C3 and C4 crops in semi-arid regions will be severely constrained as global temperatures rise. Consequently, alternative crops need to be sought out that adapt well to heat and drought and are productive despite limited access to water. Traits, such as crassulacean acid metabolism (CAM), enable economically important species such as those in the Agave genus adapt to drought and high temperatures. The succulence and high efficiency of agaves, which enables them to produce biomass with little water, underscores their feasibility as an alternative crop for semi-arid regions, such as the Sonoran Desert in the southwestern U.S. In …

Morphologic Adjustments Of Actively Evolving Highly Curved Neck Cutoffs, Derek Richards, Kory Konsoer

Faculty Publications

Neck cutoffs and their resultant oxbow lakes are important and prominent features of riverine landscapes. Detailed field-based research focusing on the morphologic evolution of neck cutoffs is currently insufficient to fully characterize cutoff evolution. High-resolution bathymetric data were collected over 3 years for the purpose of determining channel morphology and morphologic change on three actively evolving neck cutoffs. Results indicate the following general trends in morphologic adjustment: (1) a longitudinal bar in the upstream meander limb that develops near the entrance to the abandoned bend; (2) a deep scour hole in the downstream meander limb immediately downstream of the cutoff …

Faculty Publications

© 2019 The Author(s). Background: Baboons (genus Papio) and geladas (Theropithecus gelada) are now generally recognized as close phylogenetic relatives, though morphologically quite distinct and generally classified in separate genera. Primate specific Alu retrotransposons are well-established genomic markers for the study of phylogenetic and population genetic relationships. We previously reported a computational reconstruction of Papio phylogeny using large-scale whole genome sequence (WGS) analysis of Alu insertion polymorphisms. Recently, high coverage WGS was generated for Theropithecus gelada. The objective of this study was to apply the high-Throughput "poly-Detect" method to computationally determine the number of Alu insertion polymorphisms shared by T. …

Using Bim (Building Information Modeling) To Vizualize And Share Archaeological Data At Tall Hisban, Jordan, Ariel Solis, Rhonda Root

Faculty Publications

Today, the field of archaeology is seeking to expand beyond the traditional sharing of information through printed books and archaeological publications, and be more relevant by using various new technologies, such as 3-D visualization, Building Information Modeling (BIM), and interactive media. We seek to continue to advance research that is being done in these area. At Tall Hisban, Jordan (the first Madaba Plains Project archaeological site), many of these technologies are being used. However, the main objective of this project is to create a digital three-dimensional model of the Tall (entire site), showing the historical order of civilizations, how buildings …

The Future Of Reef Ecosystems In The Gulf Of Mexico: Insights From Coupled Climate Model Simulations And Ancient Hot-House Reefs, Kristine L. Delong

Faculty Publications

emperatures (SST), salinity, carbonate chemistry, and acidity. Over the last half-century, some reef communities have been disappearing at an alarming pace. This study focuses on the Gulf of Mexico, where the majority of shallow coral reefs are reported to be in poor or fair condition. We analyze the RCP8.5 ensemble of the Community Earth System Model v1.2 to identify monthly-to-decadal trends in Gulf of Mexico SST. Secondly, we examine projected changes in ocean pH, carbonate saturation state, and salinity in the same coupled model simulations. We find that the joint impacts of predicted higher temperatures and changes in ocean acidification …

Faith And Faithfulness In The Book Of Mormon, Noel B. Reynolds

Faculty Publications

The concept of covenantal faithfulness toward Yahweh that Old Testament scholars have recognized and defined over the last century turns out to be a far better account of the Book of Mormon understanding of faith in the Lord, in Jesus Christ, than are any of the competing concepts of faith that have grown out of the Christian tradition over the last two millennia. For the Nephite prophets, faith was an active concept, better understood as faithfulness—as diligent obedience to the commandments the Lord has given to those who have accepted the gospel covenant through repentance and baptism. The divine …

Covenant Language In Biblical Religions And The Book Of Mormon, Noel B. Reynolds

Faculty Publications

In this essay I have tried to provide a broad survey of the concept of covenant for Latter-day Saint students of the Bible and the Book of Mormon. I began with a sketch of the history of covenant theology in the Christian tradition showing how the early New Testament idea of a baptismal covenant was soon replaced by the Christian institution of sacraments. Although the covenant idea played little role in the historical developments of Christian theology, it did resurge in the Reformation, but without widespread theological impact.

In contrast, over the last century, the role of the covenant idea …

Late Pleistocene Site Formation And Paleoclimate At Lapa Do Picareiro, Portugal, Michael M. Benedetti, Jonathan A. Haws, Nuno F. Bicho, Lukas Friedl, Brooks B. Ellwood

Faculty Publications

© 2019 Wiley Periodicals, Inc. The cave site of Lapa do Picareiro, Portugal contains a deep (~10 m) sedimentary sequence representing much of the Middle and Upper Paleolithic, with abundant animal bones, lithic/bone/shell artifacts, and charcoal/ash in hearths. A deposition model based on 49 radiocarbon ages demonstrates average sedimentation rates of 0.1–0.3 mm a −1 between 9 and 45 ka. Extrapolation suggests an age at the base of the excavation of 65–78 ka. The cave sediments are primarily limestone éboulis derived from roof spalling, and muddy fine sediment derived from weathered soil infiltrating through bedrock joints and crevices. Bone preservation …

Wetland Biomass And Productivity In Coastal Louisiana: Base Line Data (1976-2015) And Knowledge Gaps For The Development Of Spatially Explicit Models For Ecosystem Restoration And Rehabilitation Initiatives, Victor H. Rivera-Monroy, Courtney Elliton, Siddhartha Narra, Ehab Meselhe, Xiaochen Zhao, Eric White, Charles E. Sasser, Jenneke M. Visser, Xuelian Meng, Hongqing Wang, Zuo Xue, Fernando Jaramillo

Faculty Publications

Coastal Louisiana hosts 37% of the coastal wetland area in the conterminous US, including one of the deltaic coastal regions more susceptible to the synergy of human and natural impacts causing wetland loss. As a result of the construction of flood protection infrastructure, dredging of channels across wetlands for oil/gas exploration and maritime transport activities, coastal Louisiana has lost approximately 4900 km2 of wetland area since the early 1930s. Despite the economic relevance of both wetland biomass and net primary productivity (NPP) as ecosystem services, there is a lack of vegetation simulation models to forecast the trends of those functional …

Situational Factors Influencing Receptivity To Bullshit, Mitch Brown, Lucas A. Keefer, Shelby J. Mcgrew

Faculty Publications

Individuals are motivated to maintain a sense of meaning, and enact cognitive processes to do so (e.g., perceiving structure in the environment). This motivation to find meaning may ultimately impact humans’ interpretation of "bullshit", statements intended to convey profundity without any meaning. Conversely, subtle cues threatening the meaningfulness of bullshit may elicit greater skepticism. Three studies tested situational factors predicted to heighten or diminish susceptibility to bullshit by changing motivations to seek meaning. We employed diverse methods including symbolic meaning threat (Study 1), social exclusion (Cyberball; Study 2), and manipulating cognitive fluency (Study 3). Taken together, the results indicate basic …

When Good Girls Go Bad (Or Do They?): Nymphomania And Lycanthropy In Verga’S “La Lupa”, Ilona Klein

Faculty Publications

At some point during early development, most children are afraid of the imaginary wolf under the bed or the wolf that hides in the closet at night. Traditional bedtime stories such as Little Red Riding Hood certainly do not help assuage such fears: these are atavistic dreads, similar to being scared of the dark or of death.1 In childhood culture, the wolf represents the “other,” the “furry non-human,” and almost always the viciously violent. Later, as adults, the occasional dream of wolverine violence, or of human transformation into a wolf (a lycanthropic aversion) might very well create anxiety and apprehension.2 …

Theory And The Scholarship Of Teaching And Learning: Inquiry And Practice With Intention, Nancy L. Chick

Faculty Publications

Theory in the scholarship of teaching and learning (SoTL) is the conceptual basis for the practice of SoTL—or, more precisely, the conceptual bases for the practices of SoTL—as well as the bodies of knowledge, methodological assumptions, and explanations of phenomena that are deployed (explicitly or implicitly) from a range of contexts within SoTL. Put another way, theory is thinking on a meta level, a metacognitive move in which practitioners become aware, critical, and intentional of how and why they are doing their practice. It involves taking stock of the existing conversations to move beyond definitions, to critically evaluate gaps and …

Contrasting Latitudinal Gradients Of Body Size In Helminth Parasites And Their Hosts, Tad Dallas, Alyssa Lois M. Gehman, A. Alonso Aguirre, Sarah A. Budischak, John M. Drake, Maxwell J. Farrell, Ria Ghai, Shan Huang, Ignacio Morales-Castilla

Faculty Publications

© 2019 John Wiley & Sons Ltd Aim: We examined body size scaling relationships for two developmental life stages of parasitic helminths (egg and adult) separately in relationship to latitude (i.e. Bergmann's rule), temperature and temperature seasonality. Given that helminth eggs experience environmental conditions more directly, whereas adults live inside infected host individuals, we predict stronger environmentally driven gradients of body size for eggs than for adults. Location: Global. Time period: Present day. Major taxa studied: Parasitic helminths. Methods: We compiled egg size and adult body size data (both minimum and maximum) for 265 parasitic helminth species from the literature, …

Ethnic-Racial Socialization In Early Childhood: The Implications Of Color-Consciousness And Colorblindness For Prejudice Development, Flora Farago, Kimberly Leah Davidson, Christy M. Byrd

Faculty Publications

This chapter outlines how early childhood teachers can bring children into conversations surrounding race and racism by drawing on literature on how parents of color discuss these topics. Although educators’ practices surrounding race and racism remain largely unexplored, decades of developmental psychological research indicate that parents of color engage in ethnic-racial socialization practices that are beneficial for children (Hughes et al., 2006). The established dimensions of parental ethnic-racial socialization include (1) cultural socialization, or teaching children about their ethnic heritage and instilling ethnic pride; (2) preparation for bias, or teaching children about racism and preparing them to face discrimination; (3) …

A Comparison Of Hominin Teeth From Lincoln Cave, Sterkfontein L/63, And The Dinaledi Chamber, South Africa, Juliet K. Brophy, Joel Irish, Steve E. Churchill, Darryl J. De Ruiter, John Hawks, Lee R. Berger

Faculty Publications

Prior to the recovery of Homo naledi from the Dinaledi Chamber of the Rising Star Cave system, the Middle Pleistocene fossil record in Africa was particularly sparse. With the large sample size now available from Dinaledi, the opportunity exists to reassess taxonomically ambiguous teeth unearthed at the nearby site of Sterkfontein. Teeth recovered from Lincoln Cave South and area L/63 at Sterkfontein have been considered ‘most probably Homo ergaster’ and ‘perhaps Archaic Homo sapiens’, respectively. Given the similarities shared between Lincoln Cave, area L/63, and the Dinaledi Chamber with regard to climatic/geologic depositional context and age, two teeth from the …
