Disease and Healing in Ancient Societies: Dental Calculus Residues and Skeletal Pathology Data Indicate Age- and Sex-Biased Medicinal Practices among Native Californians

The health of humans is intricately linked to the substances we ingest—both food and nondietary items. Adverse health outcomes related to smoking of such products as tobacco and other psychoactive substances are clearly established in modern populations but are less well understood for ancient communities. Grasping these dynamics is further complicated by the curative, religious, and medicinal context of many of these substances, which have often been commodified, refined, and altered in recent history. As part of a larger collaboration with the Muwekma Ohlone Tribe dedicated to understanding medicinal plant use among Native Californians, this article summarizes new metabolomic data from three Middle- and Late-Period ancestral heritage Ohlone sites: Thámien Rúmmeytak (CA-SCL-128), ’Ayttakiš ’Éete Hiramwiš Trépam-tak (CA-ALA-677/H), and Síi Túupentak (CA-ALA-565/H). The authors used an ultra-performance liquid chromatography-mass spectrometry platform to analyze chemical residues from 95 human dental calculus samples from 50 burials. Using multivariate statistics, they coanalyzed demographic and skeletal pathology data with chemical residue profiles and considered skeletal markers for a series of oral and postcranial health conditions. Results indicate sex and age biases in consumption patterns. Periodontitis stands out as the most significant local factor for changes in the oral metabolome. However, while chemical markers of oral diseases may be related to pathogen activity, associations between residues and postcranial conditions such as osteoarthritis suggest traditional curative practices and the ingestion of medicinal substances. Hence, this study yields new insights into the broader context of illness and healing in the past

Proposing a rational resilience credo for use with athletes

© 2016 Association for Applied Sport Psychology. While the reported use of Rational Emotive Behavior Therapy (REBT) is growing in sport, little is written about specific tools used by practitioners when applying REBT with athletes. The Athlete Rational Resilience Credo (ARRC) adapts Windy Dryden's (2007) original Rational Resilience Credo for application with athletes. The ARRC promotes rational beliefs in athletes, which are important for resilient responding to adverse events. The ARRC is presented in full, followed by some explanation as to its purposes, critical practitioner reflections, and guidance for its use in sport

Affective determinants of treatment engagement in violent offenders

Affective factors are likely to play a major role in determining the extent to which offenders are able to engage with, and benefit from, treatment. In this article, it is argued that the relationship between affect and treatment engagement may be understood in three ways: the access the client has to emotional states, the ability to express such states, and the willingness of the client to do this in the therapeutic session. It is suggested that affective determinants of treatment readiness can be understood with reference tomodels of emotional regulation and that attention to these affective factors in the early stages of treatment is likely to promote engagement, reduce attrition, and consequently improve treatment outcomes for violent offenders. <br /
