AbstractThe evolution and development of human mortuary behaviors is of enormous cultural significance. Here we report a richly-decorated young infant burial (AVH-1) from Arma Veirana (Liguria, northwestern Italy) that is directly dated to 10,211–9910 cal BP (95.4% probability), placing it within the early Holocene and therefore attributable to the early Mesolithic, a cultural period from which well-documented burials are exceedingly rare. Virtual dental histology, proteomics, and aDNA indicate that the infant was a 40–50 days old female. Associated artifacts indicate significant material and emotional investment in the child’s interment. The detailed biological profile of AVH-1 establishes the child as the earliest European near-neonate documented to be female. The Arma Veirana burial thus provides insight into sex/gender-based social status, funerary treatment, and the attribution of personhood to the youngest individuals among prehistoric hunter-gatherer groups and adds substantially to the scant data on mortuary practices from an important period in prehistory shortly following the end of the last Ice Age.

Heritage language variation and change provides an opportunity to examine the interplay of contact-induced and language-internal effects while extending the variationist framework beyond monolingual speakers and majority languages. Using data from the Heritage Language Variation and Change in Toronto Project, we illustrate this with a case study of Tagalog (r), which varies between tap, trill, and approximant variants. Nearly 3000 tokens of (r)-containing words were extracted from a corpus of spontaneous speech of 23 heritage speakers in Toronto and 9 homeland speakers in Manila. Intergenerational and intergroup analyses were conducted using mixed-effects modeling. Results showed greater use of the approximant among second-generation (GEN2) heritage speakers and those that self-report using English more. In addition, the distributional patterns remain robust and the approximant appears in more contexts. We argue that these patterns reflect an interplay between internal and external processes of change. We situate these findings within a framework for distinguishing sources of variation in heritage languages: internal change, identity marking and transfer from the dominant language.

Hoy en día el conejo europeo (Oryctolagus cuniculus) es considerado invasivo en varios países. Sin embargo, los motivos del inicio de la explotación de este lagomorfo en el Paleolítico Superior en la península ibérica son objeto de un intenso debate sin que todavía exista un consenso general sobre las causas que explican su introducción en la dieta de los cazadores-recolectores ibéricos. En este artículo, primero presentamos cómo su caza comenzó antes del Último Máximo Glacial (UMG), aumentando durante este periodo. Luego evaluamos las principales hipótesis del Modelo de Amplitud de Dieta (Diet Breadth Model), desarrollado a partir de la Teoría del Forrajeo Óptimo (Optimal Foraging Theory). Este modelo (a veces implícito) es el origen de algunas de estas hipótesis, pero hasta ahora nunca se había aplicado de forma concreta al UMG en la península ibérica. En consecuencia, nosotros lo hemos hecho y los resultados obtenidos no parecen apoyar las hipótesis que defienden una intensificación de la explotación del medio ambiente. Sugerimos que el aprovechamiento de este taxon en torno al UMG en Iberia podría explicarse más bien por el uso de redes entre varias personas. [fr] Bien qu’aujourd’hui le lapin de garenne (Oryctolagus cuniculus) soit considéré comme une espèce invasive dans plusieurs pays, il fait l’objet d’un débat intense quant aux raisons du début de son exploitation durant le Paléolithique supérieur dans la péninsule ibérique. Cependant, aucun consensus général n’existe afin d’expliquer les causes de son introduction dans la diète des chasseurs-cueilleurs ibériens. Ici, nous présentons d’abord que sa chasse a débuté avant le Dernier Maximum Glaciaire (DMG) et qu’elle s’est accrue durant cette période. Ensuite, nous évaluons les principales hypothèses soutenues à partir du Modèle Classique du Régime Alimentaire (MCRA; Diet Breadth Model) issu de la Théorie de l’Approvisionnement Optimal (TAO; Optimal Foraging Theory). Bien que ce modèle soit à l’origine (parfois implicitement) de plusieurs de ces hypothèses, il n’a jamais été appliqué concrètement au DMG dans la péninsule. Nous avons alors appliqué ce modèle et les résultats obtenus ne semblent pas appuyer les hypothèses soutenant une intensification de l’exploitation de l’environnement. Plutôt, nous suggérons que l’utilisation de filets par plusieurs personnes pourrait expliquer l’exploitation de ce taxon autour du DMG en Ibérie.

An increasing number of researchers support reproducibility by including pointers to and descriptions of datasets, software and methods in their publications. However, scientific articles may be ambiguous, incomplete and difficult to process by automated systems. In this paper we introduce RO-Crate, an open, community-driven, and lightweight approach to packaging research artefacts along with their metadata in a machine readable manner. RO-Crate is based on Schema$.$org annotations in JSON-LD, aiming to establish best practices to formally describe metadata in an accessible and practical way for their use in a wide variety of situations. An RO-Crate is a structured archive of all the items that contributed to a research outcome, including their identifiers, provenance, relations and annotations. As a general purpose packaging approach for data and their metadata, RO-Crate is used across multiple areas, including bioinformatics, digital humanities and regulatory sciences. By applying "just enough" Linked Data standards, RO-Crate simplifies the process of making research outputs FAIR while also enhancing research reproducibility.

This work introduces a novel analytical chemistry method potentially applicable to the study of archaeological starch residues. The investigation involved the laboratory synthesis of model Maillard reaction mixtures and their analysis through Fourier-Transform Ion Cyclotron Resonance Mass Spectrometry (FTICR-MS). Thus, starch from sixteen plant species were matured while reacting it with the amino acid glycine. The FTICR-MS analysis revealed > 5,300 molecular compounds, with numerous unique heteroatom rich compound classes, ranging from 20 (Zea mays) to 50 (Sorghum bicolor). These classes were investigated as repositories of chemical structure retaining source and process-specific character, linked back to botanical provenance. We discussed the Maillard reaction products thus generated, a possible pathway for the preservation of degraded starch, while also assessing diagenetic recalcitrance and adsorption potential to mineral surfaces. In some cases, hydrothermal experimentation on starches without glycine reveals that the chemical complexity of the starch itself is sufficient to produce some Maillard reaction products. The article concludes that FTICR-MS offers a new analytical window to characterize starchy residue and its diagenetic products, and is able to recognize taxonomic signals with the potential to persist in fossil contexts.
