Evidence for labret use in prehistory
No full textAims. Compared to occlusal dental wear, labial/buccal abrasion is seldom documented in prehistoric groups. This type of wear occurs in some ethnographic-present and living populations and leaves telltale facets on non-occlusal vestibular surfaces associated with labrets. Methods and materials. For detailed macroscopic, microscopic (binocular and SEM) and thin-sectioned analysis we focused on the early Neolithic site of Mehrgarh in Pakistan where labial/buccal wear is found in mostly older adult males. We studied 215 teeth from ten individuals from the site. From the literature and some personal observations, we review evidence from the Czech early Upper Paleolithic and many later sites in the Old and New Worlds. Results. For Mehrgarh macroscopic observations revealed numerous teeth with labial and buccal facets affecting nearly every tooth class. Binocular and scanning electron microscopy and one thin-sectioned tooth provided detailed information about the wear characteristics on the facets. Comparisons. The most striking parallels to wear at Mehrgarh come from recent Inuit and Northwest Coast Native Americans where labret use was frequent in males and females. Vestibular wear occurs in a wide variety of specimens from the early Upper Paleolithic to modern patients. Unlike Mehrgarh and earlier prehistoric groups, in many cases Native American teeth are associated with the actual labrets in the graves. Conclusion. Occlusal wear or attrition caused by dental/oral manipulations where the teeth were used as tools is different, based on the resultant facets left on the teeth and micro-wear features. In prehistoric Europe, labret use extends back, at least, to the early Upper Paleolithic. As in recent humans, the use of labrets in prehistoric groups likely represents personal adornment tied to concepts of beauty and/or achieved/acquired status
New 1 Ma old human cranial remains from Mulhuli-Amo, near Uadi Aalad, Danakil (Afar) depression of Eritrea
No full textThe iceman as a burial
No full textSince his discovery in 1991 the iceman has been widely seen as meeting a dramatic end – mortally wounded by an arrow shot while attempting to flee through an Alpine pass. A careful study of all the located grave goods, here planned comprehensively for the first time, points strongly towards the scene as one of a ceremonial burial, subsequently dispersed by thawing and gravity. The whole assemblage thus takes on another aspect – not a casual tragedy but a mortuary statement of its day
Measuring teacher self-efficacy using English language learner shadowing as a catalyst for implementation of two instructional strategies to support the academic language development of long-term English language learners
No full textThe purpose of this descriptive survey study was to (a) investigate the impact of ELL Shadowing on teachers\u27 awareness of the academic language abilities and needs of Long-Term English Language Learners; (b) assess teacher-perceived proficiency in implementing Frayer Model and Think-Pair-Share Charting instructional strategies with English learners following specially designed professional development; (c) assess teacher self-efficacy to effectively address the academic language needs of English learners following specially designed professional development; and (d) investigate the academic language performance of Long-Term English Language Learners as a result of the Frayer Model and Think-Pair-Share Charting strategy implementation. This study used an original survey created by the researcher consisting of 13 structured and 2 semi-structured questions that was administered after professional development on ELL Shadowing, the Frayer Model, and Think-Pair-Share Charting. The survey\u27s 15 questions examined teacher self-efficacy in using the 2 instructional strategies to meet the needs of Long-Term English Language Learners, how ELL Shadowing impacted teachers\u27 perspectives of English learners, and the impact of the 2 instructional strategies on English learners\u27 performance following professional development. The findings from this study indicated that: (a) the majority of teacher participants saw the benefit in ELL Shadowing increasing awareness of the academic needs of Long-Term English Language Learners and that these students often remain passively silent in the classroom; (b) teachers are slightly more comfortable using the Frayer Model than Think-Pair-Share Charting; (c) the majority of teacher participants saw the benefit in using the Frayer Model and Think-Pair-Share Charting to increase student talk, accountability, and Academic Language Development; and (d) in addition to professional development workshops, some teachers need ongoing support and coaching for full implementation of instructional strategies. It was concluded that: (a) ELL Shadowing increases awareness of Long-Term English Language Learners; (b) English learner professional development can increase teacher efficacy for supporting English learners; (c) The Frayer Model and Think-Pair-Share Charting, when used in conjunction, increase academic language development for English learners; and (d) Effective professional development requires a systems approach in order to build teacher capacity and sustainability
Core-Shell Processing of Natural Pigment: Upper Palaeolithic Red Ochre from Lovas, Hungary.
No full textOchre is the common archaeological term for prehistoric pigments. It is applied to a range of uses, from ritual burials to cave art to medications. While a substantial number of Palaeolithic paint mining pits have been identified across Europe, the link between ochre use and provenance, and their antiquity, has never yet been identified. Here we characterise the mineralogical signature of core-shell processed ochre from the Palaeolithic paint mining pits near Lovas in Hungary, using a novel integration of petrographic and mineralogical techniques. We present the first evidence for core-shell processed, natural pigment that was prepared by prehistoric people from hematitic red ochre. This involved combining the darker red outer shell with the less intensely coloured core to efficiently produce an economical, yet still strongly coloured, paint. We demonstrate the antiquity of the site as having operated between 14-13 kcal BP, during the Epigravettian period. This is based on new radiocarbon dating of bone artefacts associated with the quarry site. The dating results indicate the site to be the oldest known evidence for core-shell pigment processing. We show that the ochre mined at Lovas was exported from the site based on its characteristic signature at other archaeological sites in the region. Our discovery not only provides a methodological framework for future characterisation of ochre pigments, but also provides the earliest known evidence for "value-adding" of products for trade
