Forested settings present challenges for understanding the full extent of past human landscape modifications. Field-based archaeological reconnaissance in forests is low-efficiency and most remote sensing techniques are of limited utility, and together, this means many past sites and features in forests are unknown. Archaeologists have increasingly used light detection and ranging (lidar), a remote sensing tool that uses pulses of light to measure reflecting surfaces at high spatial resolution, to address these limitations. Archaeology studies using lidar have made significant progress identifying permanent structures built by large-scale complex agriculturalist societies. Largely unaccounted for, however, are numerous small and more practical modifications of landscapes by smaller-scale societies. Here we show these may also be detectable with lidar by identifying remnants of food storage pits (cache pits) created by mobile hunter-gatherers in the upper Great Lakes during Late Precontact (ca. AD 1000-1600) that now only exist as subtle microtopographic features. Years of intensive field survey identified 69 cache pit groups between two inland lakes in northern Michigan, almost all of which were located within ~500 m of a lakeshore. Applying a novel series of image processing techniques and statistical analyses to a high spatial resolution DTM we created from commercial-grade lidar, our detection routine identified 139 high potential cache pit clusters. These included most of the previously known clusters as well as several unknown clusters located >1500 m from either lakeshore, much further from lakeshores than all previously identified cultural sites. Food storage is understood to have emerged regionally as a risk-buffering strategy after AD 1000 but our results indicate the current record of hunter-gatherer cache pit food storage is markedly incomplete and this practice and its associated impact on the landscape may be greater than anticipated. Our study also demonstrates the potential of harnessing commercial-grade lidar for other fine-grained archaeology applications.

Background Prior to commencing a randomised controlled trial, we conducted a focused ethnography to ensure that the trial was well suited to the proposed setting. Methods A six-month observation of a Child and Adolescent Mental Health Service site in the North-East of England was undertaken to observe the site procedures, staff culture and patient care pathways. During this period, documentary data were collected and interviews were conducted with key informants to provide insight into staff perceptions of the proposed trial. The data were coded using thematic analysis and the resulting themes were verified by a second coder. Results Seventeen documents were collected, 158 h of observation and six formal staff interviews were undertaken. Four themes emerged from the data; non-clinically orientated variation in practice, diagnosis , capacity and staff economy. Non-clinically orientated variation in practice occurred when staff decisions were based upon resource availability rather than on clinical judgement. Diagnosis demonstrated differing staff confidence in making diagnoses and in the treatment of patients who had received a diagnosis. Capacity consisted of the time to attend training and the psychological capacity to consider or incorporate learning into practice. Staff economy was characterised by staff changes and shortages. There was significant interaction between the themes, with staff economy emerging as a central barrier to research. The results directly informed adaptations to the trial protocol. Conclusions An ethnographic approach has provided important insights into the individual, practical and organisational boundaries into which a trial would need to be implemented.

Identifying the driving forces behind oceanic pelagic shark movements is key to a better understanding of their life history. Some oceanic pelagic shark species have been shown to aggregate in specific regions to mate and/or exploit abundant food resources. The oceanic whitetip shark Carcharhinus longimanus, a subtropical, ectothermic, oceanic pelagic shark that has experienced severe population declines, aggregates seasonally around Cat Island (CI) in The Bahamas. Large pelagic teleosts (e.g. billfish, tunas, and dolphinfish) are abundant in this region and oceanic whitetips are anecdotally reported to feed heavily on recreationally caught teleosts. However, it was unknown whether feeding habits at CI substantially differ from longer-term feeding habits. We used tag-recapture to assess site-fidelity of adult oceanic whitetips to CI and stable isotope analysis (SIA) of 2 different tissues (blood plasma and white muscle) to compare short- and long-term feeding patterns. The relatively high recapture rate (20.3%) confirmed that individual whitetips exhibit site-fidelity to CI. The aggregation consisted of adult individuals; females were more common, more than half were gravid, and no physical or behavioral evidence of mating or parturition was observed at CI. SIA-based Bayesian mixing model estimates of short-term (near CI) diets showed more large pelagic teleosts (72%) than in long-term diets (47%), showing a spatiotemporal difference in oceanic whitetip feeding habits. This suggests that availability of large teleost prey is a possible mechanism underpinning site-fidelity and aggregation of whitetips at CI. These results provide insight into the function of one of the last known aggregations of this once-abundant top predator.

Building monuments was one way that past societies reconfigured their landscapes in response to shifting social and ecological factors. Understanding the connections between those factors and monument construction is critical, especially when multiple types of monuments were constructed across the same landscape. Geospatial technologies enable past cultural activities and environmental variables to be examined together at large scales. Many geospatial modeling approaches, however, are not designed for presence-only (occurrence) data, which can be limiting given that many archaeological site records are presence only. We use maximum entropy modeling (MaxEnt), which works with presence-only data, to predict the distribution of monuments across large landscapes, and we analyze MaxEnt output to quantify the contributions of spatioenvironmental variables to predicted distributions. We apply our approach to co-occurring Late Precontact (ca. A.D. 1000–1600)monuments in Michigan: (i) mounds and (ii) earthwork enclosures. Many of these features have been destroyed by modern development, and therefore, we conducted archival research to develop our monument occurrence database. We modeled each monument type separately using the same input variables. Analyzing variable contribution to MaxEnt output, we show that mound and enclosure landscape suitability was driven by contrasting variables. Proximity to inland lakes was key to mound placement, and proximity to rivers was key to sacred enclosures. This juxtaposition suggests that mounds met local needs for resource procurement success, whereas enclosures filled broader regional needs for intergroup exchange and shared ritual. Our study shows how MaxEnt can be used to develop sophisticated models of past cultural processes, including monument building, with imperfect, limited, presence-only data.

Interprofessional education (IPE) promotes team-based approaches to professional practice and lifelong collaboration. However, there is little consensus on its \"best practice\" in dentistry and dental hygiene curricula. This study aimed to explore dental hygiene students' perceptions and experiences of collaboration with dentistry students in an IPE program that authentically represents private practice settings and work processes. The intent was to identify what students thought would best help prepare them to work collaboratively in an oral health team once they graduated after participating in this experience. Data were collected from 40 dental hygiene student written reflections and 6 dental hygiene students through a focus group session that was audiorecorded and transcribed. Data were examined using thematic analysis. Five interrelated themes emerged: 1) understanding of roles and responsibilities; 2) hierarchical perceptions and level of experience; 3) team dynamics; 4) instructor and staff involvement and support; and 5) timing and structure of IPE activities. The findings suggest that dental hygiene students need consistent and sustained access to realistic environments in which to practise team roles and work directly with dentistry students. Opportunities to build relationships with dentistry students before working together in professional roles appear to alleviate hierarchical concerns that impede teamwork. IPE should occur throughout students' education as hierarchical perceptions appear to influence collaboration. Informal and/or non-clinical IPE opportunities should be introduced early in students' education to develop a foundation for team dynamics in later formal and/or clinical IPE activities. Students should collaborate in ways that will be reflected in professional expectations after graduation; the environment in which they learn their team role should provide the opportunity to authentically practise it.

Climate change threatens cultural heritage across the globe. Of its varied impacts, sea level rise is critically pressing because of the long relationship between humans and the ocean. Numerous cultural heritage sites lie on the world’s fragile coasts. Identifying cultural heritage sites at risk is an urgent need, but archaeological research programs do not always have the resources available to conduct large-scale cultural heritage vulnerability assessments. Given sea level rise poses myriad pressing issues, entities around the globe are developing sea level rise models for various management purposes (ecology, hydrology, real estate, etc.). These remote sensing-derived sea level rise models can be harnessed by archaeologists to assess cultural heritage site vulnerability. Here, such an analysis is realized for a northwest Atlantic Ocean coastal area experiencing relative sea level rise and with robust cultural heritage, including economically significant maritime heritage tourism. Combining archaeological and historic geospatial databases with LIDAR (Light Detection and Ranging)-derived relative sea level rise models illuminates coastal New Hampshire’s cultural heritage vulnerability. This is informative for risk monitoring, mitigation, and preservation planning, especially for cultural heritage tourism. The analysis also raises the need for discussions around what kind and whose heritage gets priority in planning for future sea level rise impacts.

Other-than-human persons and the role they play in transforming social, economic, and ideological material realities is an area of expanding interest in archaeology. Although the Anishinaabeg were an early and vital focus of cultural anthropological studies on nonhumans given their significant relationships with other-than-human persons, known to them as manitou , emerging archaeologies advancing this topic are not largely centered on ancestral Anishinaabeg sites and artifacts. This article analyzes a set of nonvessel ceramic artifacts from Late Woodland archaeological sites in the Inland Waterway in northern Michigan, which are interpreted to be ceramic renderings of manitou. I argue that these were manitou-in-clay, vibrant relational entities that are brought into being for and through use in ceremonial perspective practices related to Mishipishu—a complexly powerful, seductive, and dangerous nonhuman being known as the head of all water spirits. I contextualize the making and breaking of Mishipishu manitou-in-clay as acts of petition by hunter-fishers who had been seduced by this manitou in dreams, as they headed out on necessary but high-risk early-spring resource harvesting in the inland lakes of the Inland Waterway. This case advances insights into how relationships with other-than-human persons were coproductive of the world in the northern Great Lakes region during the Late Woodland period. Las personas que no son humanas y el papel que desempeñan en la transformación de las realidades materiales sociales, económicas e ideológicas es un área de creciente interés en la arqueología. Aunque los Anishinaabeg fueron uno de los primeros y vitales focos de los estudios antropológicos culturales sobre los no humanos debido a sus relaciones significativas con personas que no son humanas conocidas por ellos como manitou , las arqueologías emergentes que promueven este tema no se centran en gran medida en los sitios y artefactos ancestrales de Anishinaabeg. Este artículo analiza un conjunto de artefactos cerámicos no embarcados de los sitios arqueológicos de Woodland tardío en el Canal interior en el norte de Michigan interpretados como representaciones cerámicas de manitou. Sostengo que se trata de entidades relacionales vibrantes de manitou-in-clay, creadas para y mediante el uso en prácticas de perspectiva ceremoniales relacionadas con Mishipishu, un ser no humano complejo, poderoso, seductor y peligroso conocido como la cabeza de todos los espíritus del agua. Contextualizo la fabricación y ruptura de Mishipishu manitou-in-clay como actos de petición de cazadores-pescadores que habían sido seducidos por este manitou en sueños, mientras se dirigían a la recolección de recursos necesarios pero de alto riesgo a principios de la primavera en los lagos interiores de El Canal Interior. Este caso ofrece información sobre cómo las relaciones con personas que no son humanas fueron coproductivas del mundo en la región norte de los Grandes Lagos durante el período de Woodland tardío.

This paper considers the archaeological study of ritual and explores the interrelationships that exist between ideologically meaningful accounts of ritual and the material representations of ritual practice that remain for archaeological evaluation. Specifically, the paper addresses the development and antiquity of the Midewiwin ritual, a ceremonial complex that is known historically throughout the Great Lakes region. The serendipitous discovery of a linkage between the Mide origin tale of Bear's Journey and the layout of the Late Prehistoric earthwork enclosures of northern Michigan provides an opportunity to document how a ritual system is represented in the archaeological record and to evaluate how the understanding of the archaeology is altered by having access to the meaning underpinning the ritual performance. The research provides unambiguous evidence for the prehistoric antiquity of the Mide ceremony and illustrates the contribution archaeology can make to understanding the long-term processes of ritual practice and change.

Mason contends that we (Howey and O'Shea 2006) created a \"chimera\" of the Missaukee Earthworks site as a regional ceremonial center in Late Prehistoric Michigan (A.D. 1200-1600) by misinterpreting archaeological and ethnohistoric data. In considering Mason's critique, we re-emphasize the value, and methods, of studying ritual via material remains and show that Mason’s arguments simply serve to exemplify why the culture-historic approach has failed in its effort to understand the pre-contact Native cultures of the Great Lakes. Whitley contends we are misguided about the aims of archaeological studies of ritual and the place of \"meaning\" in these studies. In considering the \"meaning\" archaeologists seek in our studies of past ritual, we emphasize the problems we see in quests for what is ultimately immaterial and unrecoverable, the internal or emotive \"meaning\" of past ritual.
