Anyskop Blowout Prehistoric Dataset, Western Cape, South Africa
<p>These Stone Age archaeological datasets were collected in 2001 and 2002 by a team from the Department of Early Prehistory and Quaternary Ecology of the University of Tübingen (Germany) headed by Nicholas J. Conard. Many South African researchers collaborated on this project, with Pippa Haarhoff, John Compton, Dave Roberts, and Stephan Woodborne deserving special mention.</p> <p>The field work took place at the Anyskop Blowout (ANY1) located within the West Coast Fossil Park near Langebaanweg, Western Cape, South Africa. The field work was conducted with the help of students from the universities of Tübingen and Cape Town. The datasets are predominantly in English (with some German as well) and include field data in the MAIN table. Further analytical data for many classes of artifacts include: LITHICS, FAUNA, POTTERY, MODERN, BUCKETS, REFITS.</p> <p>All collected materials are curated by the Iziko South African Museums in Cape Town under accession numbers SAM-AA-8903 (finds collected by other teams before 2001) and SAM-AA-9007 (finds from this study, 2001-2002). Some of the finds are exhibited in the museum at the West Coast Fossil Park.</p> <p>Funding for this research project came mainly from the German Research Foundation (DFG - CO 226/5-1, 5-2, 5-5 and 5-6) and the University of Tübingen. Significant support was provided by the Iziko South African Museums, the West Coast Fossil Park, and the University of Cape Town.</p>
Hoedjiespunt Middle Stone Age Dataset, Western Cape, South Africa
<p>This Middle Stone Age archaeological dataset from Hoedjiespunt 1 was collected in 2011 by a team from the Department of Early Prehistory and Quaternary Ecology of the University of Tübingen (Germany) headed by Nicholas J. Conard. South African and European researchers collaborated on this project, with John E. Parkington, Katherine Kyriacou, Deano Stynder, Graham Avery, and Chantal Tribolo making substantial contributions. The site is located within the property of Transnet National Ports Authority in the municipality of Saldanha, Western Cape, South Africa.</p> <p>The locality of Hoedjiespunt 1 was well known as a paleontological site since at least the 1990s, when the site yielded several important Middle Pleistocene hominin remains dated between 200,000 and 350,000 years. The paleontological site also yielded a well preserved assemblage of fauna, including terrestrial and marine mammals, shellfish and ostrich eggshell. The excavators interpreted the accumulation of these finds as the remains of a hyena den. Cultural remains such as lithic artifacts were absent from the paleontological site, which is situated immediately below the archaeological site.</p> <p>The 2011 field work at the archaeological site of Hoedjiespunt 1 took place with the help of students from the universities of Tübingen and Cape Town. The datasets are predominantly in English (with some parts in German) and include field data in the MAIN table. Further analytical data for several classes of artifacts include: LITHICS, FAUNA, OCHRE, and BUCKETS.</p> <p>All of the archaeological materials collected in 2011 are curated by the Department of Archaeology of the University of Cape Town in Rondebosch, South Africa. Funding for this research came mainly from the Heidelberg Academy of Sciences and Humanities and the University of Tübingen. Significant support was provided by the Department of Archaeology of the University of Cape Town and the Iziko South African Museums.</p> <p> </p> <p>Importnat references for the paleontological excavations are listed here, while the main publications associated with the 2011 excavations are presented below in the reference section: </p> <p>Berger, L.R. & Parkington, J.E.

Fig. 2.—Bayesian phylogenetic reconstruction based on the mitochondrial gene cytochrome b (Cytb). Values above branches represent Bayesian posterior probabilities and values below branches are bootstrap values of maximum likelihood (support values <50 are not shown). The right column presents sequences GenBank accession numbers. The sequence JQ956446 is listed in GenBank as Pseudoromicia tenuipinnis but it was probably misidentified. See Table 1 for a complete list of the specimens used and main text for details of the molecular analyses.
The knowledge, attitudes and perceptions towards the Covid-19 vaccine among dental staff at the University of the Western Cape, South Africa
<p><strong>Background:</strong> Despite the well-known increased risk of exposure to the Covid-19 virus in a dental setting, vaccination rates among staff members are low. This study was aimed at understanding the knowledge, attitudes and perceptions of staff towards the Covid-19 vaccine. This information, as well as the possible associations to demographic profiles, are necessary for authorities to adequately address specific concerns and uncertainties<strong>; (2) Methods:</strong> A descriptive cross-sectional study was conducted by means of an anonymous, online, validated questionnaire.; <strong>(3) Results:</strong> 105 staff members participated. Majority of staff have received the Covid-19 vaccine but stated that they would not take the booster vaccination. Significant associations between the level of education and the knowledge, attitudes and perceptions of staff were found.; <strong>(4) Conclusions:</strong> Majority of the staff members had a positive attitude towards the Covid-19 vaccine. However, specific concerns and uncertainties were identified and will need to be addressed in order to improve vaccination rates among staff members.</p>
