    Archaeometric characterization of prehistoric pottery from Baħrija, Malta

    Get PDF
    The end of prehistory in the Maltese archipelago is characterized by the production of a problematic class of pottery, until now attested just at the site of Baħrija, on the western coast of Malta. Such a production represents a break with the tradition in terms of repertoire of shapes, style and technology and it has been interpreted as the result of contact between locals and foreign immigrants. The recent overall reappraisal of the unpublished ceramic assemblage collected during the excavations carried out at Baħrija, represents a unique opportunity to focus on the technological aspects of the production, trying to shed light on the issue of the break with the tradition and the impact of external influxes. Petrographic analysis on thin sections and chemical analyses via X-ray fluorescence spectroscopy (XRF) and laser ablation-inductively coupled plasma mass spectroscopy (LA-ICP-MS) have been carried out to characterize the Baħrija pottery production in order to interpret from a different angle the issue of the possible arrival of newcomers and establishment of a foreign enclave in Malta, which until now has been hypothesized only on the basis of the sudden emergence of the Baħrija pottery

    Study of the geomorphological and archaeological aspects of Sintra area (Portugal) as contribution to its tourist appraisal and promotion

    The Portughese town of Sintra is an UNESCO world heritage site for itscultural and environmental aspects. The town is located 30 km from Lisbon and 15km from the Atlantic Ocean, and is a touristic site in every seasons mainly for itsarchitectural qualities. This work describes the geomorphological and archaeologicalaspects of the town and the surrounding Serra de Sintra in order to give an addedvalue to tourist appraisal and promotion of the area. Serra de Sintra is an ellipticigneous massif 10 km E-W and 5 km N-S, 300-500 m above sea level. The geologicalstructure is complex but it can be simplified as a core of sienites surrounded bygranites intruded in a limestone plateau. The morphogenetic processes, besidecommon landforms such as narrow valleys, scarps and ridges, shaped a variety ofparticular granite morphologies such as round block fields, inselbergs, castle koppies,etc…. The most spectacular ones have been described and classified as geosites in adata-base. The oldest archaeological remains dates to the Mesolithic, but the area hasbeen extensively occupied during the Neolitic/Calcolithic, Bronze and Iron Ages. Inhistorical times Romans, Visigots and Arabs left some interesting architectural andlinguistic marks. All the archaeological sites have been classified according tobibliographic, museal data and field surveys. They are also all included in a data-base.GeoArchaeo-Tourist maps at 1:25,000 and 1.10,000 scales of the Serra de Sintra andSintra town are the information results collected in the geomorphological andcultural data-bases. The maps have been implemented, by means of an ArcGIScomputer programme, integrating geological, geomorphological, archaeological andhistorical aspects with the tourist infrastructures (information points, parking areas,accommodations, panoramic points, etc.) in order to obtain documents readable, simple, clear but scientifically accurate also for non-expert users. This study could besuitably simplified and summarized in a guide book, with enclosed GeoArchaeo-Tourist maps, as a contribution to improve the knowledge and appraisal of the Sintraterritory also for its landscape and archaeological aspects

    Improved high-resolution GPR imaging and characterization of prehistoric archaeological features by means of attribute analysis

    We propose a novel procedure for the analysis and interpretation of Ground-Penetrating Radar (GPR) data from archaeological data and we test the method in challenging conditions at a prehistoric settlement on the Stromboli Island (Italy). The main objective of the proposed procedure is to enhance the GPR capability of identifying and characterizing small-size and geometrically irregular archaeological remains buried beneath rough topographic surface conditions. After the basic GPR processing sequence, including topographic correction using a high-resolution Digital Elevation Model acquired from 3-D Laser Scanner, the procedure encompasses a multi-attribute analysis and iso-attribute surfaces calculation with different volume extraction solutions to emphasize vertical and lateral variations within GPR data cubes. The test was performed in cooperation with the archaeological team to calibrate the results and to provide detailed information about buried targets of potential archaeological interests to plan further excavations. The results gave evidence of localized buried remains and allowed detailed preexcavation planning. The archaeological excavations validated the results obtained from the GPR survey. The research demonstrates that the proposed GPR procedure enhances the ability to identify and characterize archaeological remains with high accuracy even in complex surface and subsurface conditions. Such logistical situation is very common, particularly in prehistoric sites, which are often characterized by discontinuous, small and irregular targets that cannot be identified by standard processing and analysis strategies

    Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

    : The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity > 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI
