    Genetic Relationships between Mesoamerican Ancient Populations and with American Greater Southwest and Caribbean Populations Close to Mesoamerican Borders

    No full text
    Mesoamerica is a cultural and geographic region with a northern boundary adjacent to the American Greater Southwest and a southeastern boundary that includes the Maya area, which is adjacent to the Caribbean. These regions are of interest to analyze genetic structure, ancestry, and gene flow between the ancient populations. We identified the mitochondrial DNA haplogroups and haplotypes in 19 colonial and 10 pre-Columbian Maya from Xcaret and 6 Paquimé individuals. We analyzed our data together with 603 ancient individuals and with 95 colonial and 502 pre-Columbian individuals. The results show clear genetic differences among Mesoamerica, American Greater Southwest, and Caribbean regions. High frequency of haplogroup A in Paquimé and Mine Canyon and the distribution of its haplotypes in the networks suggest these populations are probably genetically related with both Mesoamerican and the American Greater Southwest populations. The genetic structure of the Maya is due to common ancestry, and it was maintained by geographic isolation and gene flow mostly between Mayan populations. The Spanish conquest did not change this structure in the Maya from Xcaret, Quintana Roo. Although populations from Central Mexico are not genetically homogeneous, they are clearly different from Maya. Teotihuacan and Cholula were contemporary cities that allied to control the region, but they show genetic differences that could be related to a distant common ancestry; they probably descended from the same group but separated very early, before their arrival in Central Mexico

    Protecting the Integrity of Archives

    This article examines the problem of fraudulent and stolen materials being introduced into archives. If these issues become common enough, people will not trust archives or history itself. Archivists can fight these problems by learning how to spot potential sellers of stolen or fraudulent items. They can also catalog unique aspects of their collections and share them on the internet, dedicate more resources to security, and hire experts when items’ authenticity is called into question. The most helpful step they can take, however, is being so diligent about establishing provenance that provenance becomes a security measure in itself. Ultimately, resources and funding will determine how much archives do to ensure their collections’ integrity

    Library Publishing Curriculum Introduction Module: Introduction Narrative

    In 2018, The Educopia Institute and the Library Publishing Coalition (LPC), in partnership with the Public Knowledge Project (PKP), NASIG, and BlueSky to BluePrint, released the first iteration of the “Library Publishing Curriculum,” a suite of synchronous and asynchronous professional development offerings for librarians. The four initial modules—Content, Impact, Policy, and Sustainability—were funded by the Institute for Museum and Library Sciences and address major competencies in library publishing. As part of the sustainability plan for these grant deliverables, the LPC created an editorial board that would steer future iterations of the curriculum. They took as their first task a step back from the existing modules to provide an introduction that would frame the rest of the curriculum for complete newbies to library publishing. This Introduction Module offers an entry-level approach that explains the very fundamentals of library publishing that the discipline has inhabited over the last decade—explaining much of the implicit work of who, what, when, where, and why of library publishing

    Contrasting Male and Female Dietary Life Histories: A Case Study at an Ancestral Muwekma Ohlone Heritage Site in San Jose, California

    Stable carbon and nitrogen isotope analyses of bones and teeth at the ancestral heritage Muwekma Ohlone site of Yakmuy ´Ooyákma-tka (“Place of the East Ridge Site”; CA-SCL-215) reveal significant differences in the dietary life history of males and females. Overall, isotope data indicate that site inhabitants were primarily dependent on low-trophic-level foods, likely plants, and minor amounts of marine food for their main source of dietary protein. From tooth dentin serial samples, we found that males and females were similar for δ13C in early childhood (age 1–9 years), but boys were elevated in δ15N by 0.6–1.0‰ relative to girls, indicating boys were accessing slightly greater amounts of higher-trophic-level foods, such as meat from game. The sex-biased difference in δ15N diminishes during the second decade of life, as female δ15N values increase and become equal to males. However, a difference in δ13C emerges during the second decade: female δ13C values are elevated relative to males. This could indicate that teenage females consumed higher amounts of low-trophic-level, marine-derived protein, such as shellfish. During later adult years the difference in δ13C disappears, while males again show an increase in δ15N relative to females. Although these differences are small, they reveal important sex-biased life history patterns during childhood and adulthood in this ancient community

    More Than Ethics: Changing Approaches to Research in Human Biology

    Get PDF
    Work in biological anthropology and human biology that engages with, extracts, manipulates, analyzes and disseminates biological data from and associated with people requires serious ethical investment as central to method, theory, and practice. However, ethics is not enough. Moving beyond a call for better (or more) ethics there is a core need for anthropological, historical, anti-racist/anti-colonialist method and theory in dealing with human data (existing, newly collected, and future collections). But there are structures in the academy, historical, financial, hierarchical, discriminatory, that impede sincere and effective actions to make such changes. Encouragingly, calls for structural change, and some actions entailing it are underway. But individual efforts are not enough. Systemic profession-level processes need to be addressed

    Patient-reported outcome measures should guide need for specialty referral in atraumatic shoulder and knee pain Introduction: Patient-Reported Outcome Measurement Information System (PROMIS) questionnaires have proven utility as an augment to monitoring clinical outcomes in an orthopedic setting. However, there is minimal information regarding the use of PROMIS questionnaires as a screening tool for referrals to specialty providers. The purpose of this study was to evaluate the relationship between PROMIS scores and the level of care and treatment provided by all providers across an orthopedic sports medicine department. Methods: 500 randomized charts were reviewed between January 1, 2023 and May 31, 2023. All patients 40 years or older who presented to any orthopedic provider within the sports medicine department for atraumatic shoulder or knee pain met inclusion criteria. Data collected included general demographic information, PROMIS, treatment plan at the initial clinic visit, and ICD-10 codes from that same visit. Statistical analysis was performed, first descriptively, and then using paired Student’s t-tests to evaluate the relationship between PROMIS scores and the recommended treatment. Results: 341 patients met inclusion criteria. The average age of the cohort was 60.30. There were 145 patients who presented for shoulder concerns and 196 who presented for knee concerns. Average PROMIS physical function (PROMIS-PF) score was 40.99, average PROMIS upper extremity (PROMIS-UE) 36.54, and average PROMIS pain interference (PROMIS-PI) 61.12. Providers recommended conservative treatment for 251 patients. Additional work-up was recommended for 215 patients – 115 received an injection, 165 had advanced imaging ordered, only 10 were indicated for surgery, and 19 were referred to a different subspecialty. The most common ICD-10 codes for patients presenting with knee concerns were diagnosis codes for primary knee osteoarthritis. The most common ICD-10 codes for patients presenting with shoulder concerns were more variable. When comparing those who were recommended conservative management only with those who required additional work-up or more invasive treatment, PROMIS-PF (p \u3c 0.001), PROMIS-UE (p = 0.013), and PROMIS-PI (p = 0.002) were all found to be significantly associated. Discussion: In patients with atraumatic shoulder and knee pain, PROMIS scores are a useful prediction of management, with PROMIS scores indicating greater disability predicting the likelihood of further diagnostic work-up or more invasive treatment recommendations. PROMIS scores should be considered when ordering a referral for patients with atraumatic shoulder or knee pain to prevent unnecessary specialty service appointments which can be costly for both the patient and the health system
