The peak(s) and ending of an experience are defining moments for how an experience is remembered afterwards. An important factor contributing to the likelihood of engagement in an APS is a positive previous experience (with the same or a similar system). Show less

Financial support by extended family affect interactions athealthcare facilities. They are crucial for the attainment of SustainableDevelopment Goal 3. Literature review suggests that remittance-flows havepositive impact on the quality of health care; clients are part of socialnetworks and remitters are active influencers in such networks. Remittersengage in the situation the patient is facing.Methods: We test a remitter-inclusiveapproach to information-sharing in healthcare. We investigate how this sharing increasesthe decisions on healthcare services. We hypothesize that sharing ofinformation contributes to a more positive Western-oriented health orientation,also in Africa.Results: Healthcare is rarely an individualaffair. Langen[1]described a paradigm clash of Western healthcare with traditional Africanapproaches. Hence, bridging of health care paradigms is important. Remitters,living overseas, are immersed in the context of Western-based health care. Theyrefer to their understanding, experience and knowledge of such care. Remittersthat contribute directly to the patient’s challenge are influential. They are trustedsources of information. Their knowledge augments local information sources. Inthe process of sending remittances for health, relatives in the diaspora discusshealth-issues within social groupings. Experiences, expectations, and health-relatedinformation are exchanged. These exchanges shift attributed values and communalattitudes towards the health-services and the local knowledge base of thehealth-challenges at hand. Conclusions and Recommendations: Involvementof overseas remitters in information exchange on options of patients canimprove the quality of the decision-making and their remittances can contributeto expand health-coverage and quality of healthcare.

Show moreIn 2018 we initiated a geoarchaeological investigation of Umhlatuzana rock shelter. Our aim is to clarify the depositional environment of the Middle and Later Stone Age (MSA-LSA) assemblages (~70 – 20 ka), in light of suggestions of post depositional sediment movement (Kaplan 1990). The Pleistocene sequence shows few visible stratigraphic boundaries. Sedimentological analysis allows us to evaluate the depositional environment. Show less

Show moreThe collection of the black minerals comprised primarily of manganese dioxide (MnO2) by Neandertals during the late Middle Palaeolithic in France is a known archaeological phenomenon, with some of these blocks exhibiting evidence of having been abraded to produce powder [1,2]. This has generally been interpreted as resulting from the production of black pigment that may have been applied to the body as a form of symbolic expression [3]. However, Heyes and colleagues [4] demonstrate that MnO2 can reduce the auto-ignition temperature of wood by upwards of 100°C and suggest that this special pyrotechnic property of powdered MnO2 may have been appreciated by Neandertals. Specifically, they suggest that the addition of MnO2 to tinder materials may have aided in fire-making. Recent findings suggesting that late Neandertals were producing fire by artificial means as early as 50,000 years ago lend credence to this hypothesis [4]. The purpose of the study described here is to test the utility of MnO2 as a tinder enhancer during actualistic fire-making experiments. The flint-and-pyrite fire-making method was employed to produce sparks that were directed onto different types of tinder, both with and without added MnO2, to determine if and the degree to which this material improves the ability of the tinders to capture sparks, allowing them to propagate into a glowing ember. The initial results of this study lend support to the hypothesis of Heyes and colleagues by demonstrating that MnO2 improves the spark capturing efficiency of tinder material over untreated tinder, thereby reducing the time and energy required to produce fire using the percussive fire-making method. However, it was also observed that the incorporation of pyrite dust into the untreated tinder over the course of the experiments appeared to improve its ability to capture sparks, lending to the idea that pyrite powder added to tinder prior to making fire could also expedite the process and largely negate the need for collecting MnO2 for this purpose.[1] Pitarch Martí, A., d'Errico, F., 2018.

Show moreUmhlatuzana is an important site for the study of modern behavior during the Middle and Later Stone Age in South Africa. The site was excavated in the 1980s by Jonathan Kaplan, who observed a complex Pleistocene stratigraphy and suggested that the sequence may have been impacted by sediment movement. The site formation is poorly understood with a lack of clear sedimentary boundaries in the Pleistocene deposits. In 2018, a high-resolution geoarchaeological study of the site was initiated. We re-excavated part of the site applying state-of-the-art methods and techniques designed to clarify the stratigraphy and the archaeological context. We present the results of our field observations, complemented by an evaluation of the recorded find density to reveal diachronic changes in the character of occupation. We suggest that the Pleistocene Later Stone Age occupations at the site may have been characterized by a low occupation intensity. With a clearer stratigraphic understanding of the site, we plan to study the archaeological materials and assess whether the existing collections are representative. Additional geoarchaeological analyses are underway to address outstanding questions on the stratigraphic integrity of the site. Show less

Show moreUmhlatuzana rock shelter is an important archaeological site for the study of the Middle and Later Stone Age in South Africa (~70,000 BP - 1,800 CE). The site was first excavated in 1985 by Jonathan Kaplan within a limited timeframe and was reported to have a complicated stratigraphy. One of the main problems in comprehending the formation processes of the site was the lack of clear stratigraphic boundaries in the Pleistocene deposits. In 2018, a high-resolution geoarchaeological study of the site was initiated. We re-excavated part of the site applying state-of-the-art methods and techniques designed to clarify the stratigraphy and the archaeological context.Our stratigraphic assessment of the site is based on a combination of field observations with geospatial, sedimentological, and geochemical analyses. Specifically, we have conducted grain-size, pH, and Loss-on-Ignition analyses. Within the Holocene part of the sequence pH and Loss-on-Ignition analysis confirms the presence of combustion features. Within the lower part of the sequence, our results suggest differential preservation across the sequence, explaining the absence of faunal remains and charcoal in several units. In addition, based on our analysis of piece-plotted finds, we suggest that the Pleistocene Later Stone Age occupations at the site may have been characterized by a low occupation intensity. Additional geoarchaeological work including micromorphological analysis are underway to address outstanding questions on the stratigraphic integrity of the site. With a clearer stratigraphic understanding of the site, we plan to study the archaeological materials and assess whether the existing collections are representative. Show less
