Urubici Rock Art Project
No full textThe Urubici Rock Art Project aimed to document pre-Columbian petroglyphs located in the Avencal 1 site (Sao Jaoquim National Park, Santa Catarina state, Brazil) using Polynomial Texture Mapping (PTM). In the associated article we evaluate the application of PTM in terms of information gain over traditional techniques. Avencal is one of the most recognized petroglyph sites in the southern Brazilian highlands. This study is the first detailed analysis of the site since it was recorded five decades ago. The record produced with PTM is more complete in comparison to preceding sketches. Furthermore, its utility as a prospection tool is underscored by revealing the existence of multiple eroded motifs for the first time. The site is one of the largest of several open-air petroglyph sites located within the Canoas watershed. The project was carried out by Rafael Corteletti and Philip Riris, with logistical support from the national park service of Sao Joaquim, as well as with some additional equipment lent by Marcelo Sabiá and Carolina Medeiros. Some hypothesized sequences of production for specific panels and multiple techniques of engraving used at Avencal 1 are also discussed. Following our study, it is clear that PTM has applications for both analysis and conservation of pre-Columbian rock art
Exploring the spatial structure of pre-Columbian cultural landscapes in the Alto Paraná (Misiones province, Argentina)
No full textThis thesis investigates new approaches to analysing and interpreting the spatial structure of pre-Columbian cultural landscapes in the eastern La Plata basin, through two case studies the upper watershed of the Río Paraná, Misiones province, Argentina. Drawing on ‘non-site’ and ‘distributional’ archaeological theory to establish a robust spatial framework, the first case study concerns the organization of lithic technology in a sample constructed from survey data recorded during June and July 2013 in Eldorado Department. Point pattern data, combined with a desk-based analysis of stone tools, forms the baseline for the application of a family of spatial statistical analyses of surface archaeology derived from Ripley’s K function, and supported by Monte Carlo simulation. These methods succeed in detecting significant technological trends at multiple spatial scales. The results are interpreted as a long-term accumulation of material deposited through different systems of land use, which overlap and blend in a palimpsest of occupational events that are irreducible to their individual episodes. The findings imply that the notion of archaeological ‘sites’ is unfit for the purpose of studying past cultural processes in the region. The results also show that surface data possess significant potential for generating new insights on pre-Columbian settlement patterns in both Misiones and its broader regional context.In the second case study, the role of monumental architecture in the later pre-Columbian period of Misiones is investigated with a geospatial model. It tests the emergence of territoriality among southern proto-Jê groups as a function of differential access to mound and enclosure complexes. Through a computational approach that combines archaeological and simulated random data, the model is able to discern different hierarchical modalities of accessibility to a sample of southern proto-Jê funerary earthworks. The results demonstrate that the model succeeds in characterizing hereto unknown patterns of structured mobility that existed in relation to these distinctive elements of the later Holocene built environment. Together with a focused point process model using a larger sample of monuments from Rio Grande do Sul, Brazil, these efforts demonstrate that employing quantitative methods allow archaeologists to move from conceptual models to robust explanatory frameworks in the context of understanding pre-Columbian socio-political complexification.In sum, it is argued that standard practice of collecting and interpreting surface data in the wider study region fundamentally mischaracterizes the variability, temporality, and spatial scale of this record. Adopting non-site methods and theory offers a solution to this problem. The approaches are evaluated in the Alto Paraná study area in terms of the new interpretative perspectives they enabled. New avenues of enquiry for research aiming to reconstruct past land use are presented based on the findings, including specific improvements concerning survey method and integrating excavated data

Full text linkU’lum, Bakhrul, 2018. Harmonisasi dan Kerukunan Umat Beragama (studi kasus Koeksistensi umat beragama di Daerah Udan Riris Tlogosari Kulon Kecamatan Pedurungan Kota Semarang). Semarang: Fakultas Ushuluddin dan Humaniora UIN Walisongo Semarang.
Skripsi ini adalah salah satu kajian ilmiah yang membahas tentang koeksistensi atau hidup berdampingan antara umat Kristen, Protestan, dan Hindu secara harmonis tanpa adanya konflik, ataupun permasalahan terkait agama di Wilayah Udan Riris Tlogosari kulon, Yang mana melihat Fenomena dunia terkhusunya di Indonesia banyak sekali kasus penistaan yang mengatasnamakan agama. Dan penelitian ini memberikan batasan masalah yaitu Bagaimana bentuk koeksistensi yang dilakukan masyarakat di Daerah Udan Riris Tlogosari Kulon, Kecamatan Pedurungan, Kota Semarang, dan apa Peran agamawan dalam Koeksistensi Umat Beragama masyarakat di Daerah Udan Riris Tlogosari Kulon, Kecamatan Pedurungan, Kota Semarang.
Serta tujuan yang ingin di capai dalam penelitian ini adalah Untuk memahami bentuk koeksistensi umat beragama di Daerah Udan Riris Tlogosari Kulon, Kecamatan Pedurungan, Kota Semarang. dan Agar mampu memahami pentingnya peran agama dalam koeksistensi Umat Beragama di daerah udan riris Tlogosari kulon, kecamatan Pedurungan, kota Semarang, metode penelitiang yang di gunakan adalah field reserch atau penelitian lapangan, dengan tujuan yang menggambarkan fenomena koeksistensi umat beragama antara masyarakat Kristen, Protestan, dan Hindu, secara sistematis dari suatu fakta secara faktual dan cermat.
Hasil penelitian ini menunjukkan bahwa bentuk koeksistensi umat beragama yang ada di wilayah Udan Riris adalah dengan melakukan kegiatan tolong menolong, dan silaturahmi dari satu rumah kerumah yang lain, karena hal itulah faktor utama kehidupan berdampiangan serta menjadi ciri tersendiri masyarakat atas koeksistensi yang ada di wilayah Udan Riris ini. Adapun faktor yang mendukung terjadinya harmonisasi di wilayah Udan Riris yaitu : 1) ajaran agama, 2) Peran Agamawan, 3) sikap kekeluargaan/saling memahami. Dan untuk faktor penghambatnya adalah: 1) pemahaman agama yang kurang mendalam, 2) kurangnya pemahaman akan Harmonisasi dan kerukunan umat beragama. Kemudian peran agamawan dalam koeksistensi umat beragama di Daerah Udan Riris Tlogosari Kulon, Kecamatan Pedurungan, Kota Semarang yang diamatai melalui kegiatan sosial yang dilakukan oleh para tokoh agama yang saling berkunjung dari satu rumah kerumah yang lain untuk menciptakan rasa kepercayaan yang tinggi, saling menghargai pada saat melakukan ibadah, serta penyampaian kepada umat mereka untuk terus menaga perdamaian tanpa pandang bulu agama

Electronic Supplementary Material for: The biogeography of population resilience in lowland South America
No full text<p>## Electronic Supplementary Information for "The biogeography of population resilience in lowland South America" chapter</p>
<p>This repository holds the code and data for reproducing the analysis in the chapter "The biogeography of population resilience in lowland South America", forthcoming in the Oxford Handbook of Resilience in Climate History. It also contains supplementary information on the statistical modelling undertaken as part of the aforementioned work. </p>
<p>The code comprises five principal sections, plus setup:</p>
<p>0. Setup & data loading<br>1. Data processing and display<br>2. Radiocarbon analysis<br>3. Statistical modelling<br>4. Output<br>5. Supplementary output</p>
<p>The code features an extended version of the p2pPerm function: (https://github.com/philriris/p2pPerm) that was first introduced in Riris and De Souza (2021) (https://doi.org/10.3389/fevo.2021.740629), here called the `resmet` (RESilience METrics) function. </p>
<p>In addition, the code is accompanied by three datasets:</p>
<p>- A table containing archaeological radiocarbon dates from lowland tropical South America <br>- A shapefile of South American ecoregions, original data available here: http://ecologicalregions.info/data/sa/<br>- A table of domesticated Neotropical plants resolved in Amazonian palaeoecological records, after Iriarte et al. (2020)(https://doi.org/10.1016/j.quascirev.2020.106582)</p>
<p>Briefly, the georeferenced radiocarbon data used in the paper have been compiled from a wide range of sources, including Goldberg et al. (2016), Riris & Arroyo-Kalin (2019), Napolitano et al. (2019) Arroyo-Kalin & Riris (2021), De Souza & Riris (2021), and Bird et al. (2022). These sources have been extensively cross-checked for duplicate lab codes, variation in site naming conventions, and reported locations, in order to minimise errors arising from these variables. It does not purport to be error-free, although it is adequate for the current analysis. </p>
<p>As well as its use in the production of Figure 1, the ecoregions shapefile has been intersected with the radiocarbon date locations to append this information to `rhdata.csv`. An extended description and rationale for its use can be found in the main text. </p>
<p>For the convenience of the end-user, an additional file containing the main results (metrics_regular.csv) is included. The data contained in this table is the subject of section 3 of the code, Statistical Modelling. It forms the basis of the discussion in the chapter. </p>
<p>Data cleaning was carried out manually on the raw output of the `resmet` function to remove false positives from the table. These "events" are either: a) statistically significant downturns present in periods where, logically, no humans should be present, e.g. in the Greater Antilles before ~6000 cal BP, or: b) downturns where there are no minima in the summed probability distributions of calibrated radiocarbon dates, returning nonsensical resilience metrics. Removing these data rows introduces errors to the variable Cumulative, which counts the cumulative number of downturns detected by the `permTest` function in `rcarbon`. The file version of the output in this repository should be considered authoritative for present purposes, as these counting errors in Cumulative have been manually fixed too. </p>

A reconstructed reduction sequence for curved bifacial stone tools from the eastern La Plata Basin, Argentina
Full text linkA distinctive regional lithic industry is found in the eastern La Plata basin, known as the Altoparanaense culture in northeastern Argentina, and the Humaitá tradition in southern Brazil. These archaeological cultures are recognised on the basis of large bifacial tools. The earliest deposits are dated to the ninth millennium BP, and elements of these industries continue to be produced into the post-contact period (8640±95 to 310±50 cal BP). One of the most characteristic features of the assemblages in the region is the presence of a particular class of bifacial tool known as “curved cleavers”, whose name stems from their distinctive asymmetrical shape. We describe the reduction sequence of these tools based on a spatially extensive sample from Misiones province, Argentina. This study provides for the first time a full chaîne opératoire for curved cleavers and compares it to the findings of the only published experimental study. We use a logistic regression model to verify the reconstructed five-stage reduction sequence and further support it with a metric analysis of artefact attributes within each identified stage of reduction. Our results support the conclusion that many bifacially reduced artefacts encountered in the larger study region may actually be unrecognised pre-forms of curved cleaver
