Identifying and Investigating Deeply Buried Activity Areas at the La Prele Site
Before 2023, excavations at the La Prele site identified three hearth-centered areas associated with mammoth remains. In 2022 and 2023, more than 150 augers across the site suggested the presence of a bone bed and a fourth activity area with the potential for dense archaeological deposits. Here we report preliminary results comparing the expected versus actual artifact densities to evaluate the use of auger surveys for identifying artifact cluste…
Bruce Huckell and the Folsom Record of the West Mesa, New Mexico
The West Mesa is an expansive Eolian plain atop a basalt-capped terrace of the Rio Grande in central New Mexico. Seminal work carried out in the 1960s–1970s led to the identification of an abundant Paleoindian record across the surface; Bruce Huckell initiated a program of renewed investigation in the region in the late 1990s. He, along with students and volunteers, conducted archaeological surveys and excavations at Rio Rancho, Boca Negra Wash, …
Prevalence of Tourette syndrome among children and adolescents in the United States, 2016–2022
Based on nationally representative data, this study found that the national prevalence of TS among the US children and adolescents differed by sex and race/ethnicity but remained stable from 2016 to 2022

Association Between ICD-10 Codes for Social Needs and Subsequent Emergency and Inpatient Use
BACKGROUND: International Classification of Diseases, 10th revision Z codes capture social needs related to health care encounters and may identify elevated risk of acute care use. OBJECTIVES: To examine associations between Z code assignment and subsequent acute care use and explore associations between social need category and acute care use. RESEARCH DESIGN: Retrospective cohort study. SUBJECTS: Adults continuously enrolled in a commercial or …
Prediabetes prevalence and awareness by race, ethnicity, and educational attainment among U.S. adults
Introduction: Racial and ethnic minority groups and individuals with limited educational attainment experience a disproportionate burden of diabetes. Prediabetes represents a high-risk state for developing type 2 diabetes, but most adults with prediabetes are unaware of having the condition. Uncovering whether racial, ethnic, or educational disparities also occur in the prediabetes stage could help inform strategies to support health equity in pr…
The Geochronological and Geoarchaeological Context of the Clovis-Age La Prele Mammoth Site (48CO1401), Converse County, Wyoming
The La Prele Mammoth site (48CO1401), located in Converse County, Wyoming, contains a Clovis-age occupation associated with the remains of a subadult mammoth (Mammuthus columbi). In this paper, we present the geochronological and geoarchaeological context of the site. The La Prele Mammoth site is buried in an alluvial terrace of La Prele Creek, a tributary of the North Platte River, which acts as an important migration corridor through the Rocky …
Behavioral Assessment and Treatment via Telehealth for Children with Autism
Functional analyses (FA) and functional communication training (FCT) are the most commonly used behavioral assessment and treatment approaches via telehealth for children with autism spectrum disorder (ASD) who display challenging behavior. The FA + FCT telehealth model has been shown to maintain treatment effectiveness (i.e., child behavioral outcomes and parent acceptability), as well as demonstrate treatment efficiency (i.e., cost savings). Ho…
Dukha Mobility in a Constructed Environment
Diverse theoretical perspectives suggest that place plays an important role in human behavior. One recent perspective proposes that habitual and recursive use of places among humans may be an emergent property of obligate tool use by our species. In this view, the costs of tool use are reduced by preferential occupation of previously occupied places where cultural materials have been discarded. Here we use the model to generate five predictions f…
Occupancy and the Use of Household Space Among the Dukha
Archaeologists commonly encounter the occupation surfaces of ephemeral prehistoric houses. Within those spaces, artifacts can exhibit considerable spatial structure raising the question of what that structure can tell us about human behavior. We explore a simple site-formation model in which household occupancy, defined here as the average number of individuals who simultaneously occupy a house, positively predicts artifact dispersion. We confron…
Spatial Expression of Kinship among the Dukha Reindeer Herders of Northern Mongolia
Pastoralism represents a crucial shift in the relationship between humans and animals that permeates all aspects of culture. One aspect of this transition is changes to settlement and camp structure. Previous studies indicate pastoralists situate themselves in areas suitable for their domesticated animals as opposed to foragers who situate themselves closer to consumable natural resources, such as food and raw materials. Building on these past st…
Mobility at the scale of meters
When archeologists discuss mobility, we are most often referring to a phenomenon that operates on the scale of kilometers, but much of human mobility, at least if measured in terms of frequency of movement, occurs at much smaller scales, ranging from centimeters to tens of meters. Here we refer to the movements we make within the confines of our homes or places of employment. With respect to nomadic peoples, movements at this scale would include …
Entangling Migration History
This collection of essays offers two different contributions to American immigration historiography. The editors' introduction provides a valuable primer on the recently emergent approach of entanglement theory, described by the historian Christian Goeschel as “a dynamic theory of crossovers, transfers, and exchanges.” In Entangling Migration History Benjamin Bryce and Alexander Freund provide a pithy intellectual genealogy of the constituent app…
Latino Population Growth and Hospital Uncompensated Care in California
Objectives. We examined the association between the size and growth of Latino populations and hospitals’ uncompensated care in California. Methods. Our sample consisted of general acute care hospitals in California operating during 2000 and 2010 (n = 251). We merged California hospital data with US Census data for each hospital service area. We used spatial analysis, multivariate regression, and fixed-effect models. Results. We found a significan…
Evaluating the Contemporaneity of Households at the Eden-Farson site
Archaeologists often rely on absolute dating methods, but the standard deviations associated with these approaches often leave us wondering what to make of spatially related archaeological units, such as adjacent sites, clusters of features or regional-scale investigations. This issue is particularly relevant to the Shoshone Protohistoric site of Eden-Farson located in southwest Wyoming. The campsite consists of at least 11 discrete excavation un…
Quantifying the energetic returns for pronghorn
Becoming a Promotora
Drawing from role theory, this study sought to explore the effects of assuming a new role on Latina community health workers (CHW) participating in a cervical cancer prevention program in a new Latino immigrant community located on the East Coast of the United States. Through a series of in-depth, Spanish language interviews with the 4 participants, the researchers explored the process and effects of assuming and enacting the CHW role through a n…
