This paper describes two youth participatory action research initiatives undertaken in East Palo Alto, CA, USA, as part of university–community partnerships. We discuss the process of engaging youth researchers to build youth skills, facilitate relationships with community-based organizations, and enhance study integrity. We report interview and artifact data that address: (1) how the youths' involvement in the research process affected their sense of place and self-efficacy for creating community change; (2) how the youths' interactions with adult community leaders shifted adult perceptions of youths' abilities and roles in the community; and (3) how the initiatives affected youth and adult participants' perspectives of the university.  相似文献

This article focuses on an eye‐witness account of a series of sermons preached in Brown's River, Tasmania, in 1836–1838 by Harriet Pullen — arguably the earliest documented instance of female preaching in Australia. It explores the context, motivation, and reception of Harriet's preaching, comparing it with the two main paradigms of female preachers that can be found in the contemporary literature: the preacher as “prophetess” and the preacher as “helpmeet.” While Harriet has much in common with both paradigms, she does not fit neatly into either. Her preaching activity is best understood as a convergence of the two paradigms, within a context of domestic church gatherings in a frontier missionary situation.  相似文献

Archaeological sites dating from the Preboreal are of special interest since they mark the turning point in the transition between the cultures of the Late Pleistocene and the Holocene. In spite of their relevance only few sites in the Western and Central European Plain have become known, thus providing an inhomogeneous basis for further hypotheses. In particular, sites in the widespread aeolian landscapes have been neglected for a long time due to their uncertain genesis, dating problems and obviously insufficient preservation. Our investigations of the Haverbeck site, situated in sandy aeolian substrate, seek to enhance knowledge about the Preboreal Mesolithic. The well-preserved archaeological spatial, technological and functional patterns and the geoarchaeological site formation were studied. Sedimentological and palaeopedological analyses, supported by 14C and OSL dating results, revealed that artefacts were deposited during the Preboreal on sands which had accumulated during the Younger Dryas and were reactivated in subsequent periods (Atlantic, Subboreal, Subatlantic). In spite of these processes, the artefacts remained unimpaired in their relative horizontal positions, enabling spatial analyses, which show a zonal differentiation and a prevalence of retooling and replacing activities. These results offer an insight into spatial and functional differentiations of the local Early Mesolithic subsistence, evidently including particular places for gathering and processing raw material. A comparison between the microlithic spectrum left behind and the number of points produced as concluded from the microburins indicates a greater typological differentiation than previously assumed for the Early Mesolithic. The remarkable variability of scraper forms obviously intentionally abandoned in a high number and replaced by new tools emphasizes the strong influence of functional elements on the typological assemblage composition. It is suggested that Early Mesolithic assemblages could display rather functional requirements or tasks performed than significant chronological or regional influences.  相似文献

The Hawkesbury River of New South Wales, Australia is under increasing environmental stress. Pre-anthropogenic and current levels of heavy metal concentrations have been established for bed sediments between Windsor and Broken Bay. Sediment heavy metal concentrations in the main channel of the Hawkesbury River are close to background, but are substantially elevated in the headwaters of Berowra Creek, Cowan Creek and in southeast Pittwater. The Berowra Waters area and the upper catchment contribute both heavy metals and organochlorines/pesticides to the Berowra estuary. High contaminant levels above and below the Hornsby sewage treatment plant, and above and below the Calna Creek sewage treatment plant, make an assessment of the contribution by these plants difficult. Analyses of oyster tissue from the middle and lower reaches of the estuary indicate that heavy metal contaminants are entering the food chain.  相似文献

This paper traces perceptions of Papuan ‘fearfulness’ in the records of the Freycinet, Duperrey and Dumont d’Urville expeditions. These French scientific expeditions explored Oceania during the period of the Bourbon Restoration in France and stopped at Waigeo Island and Teluk Doreri in West Papua. The paper aims to elucidate not only the nature and significance of perceptions of fearfulness in the Papuan encounters, but also the Indigenous agency, French cultural assumptions and evolving ethnographic practices that complicated and were papered over by emergent ‘racial’ classifications. Despite their acknowledgement of diversity and their increasing familiarity with their hosts, the voyagers presented fearfulness as the Papuans’ most characteristic trait. A hardening of this claim in the published accounts may be attributed partly to the development of a racial classification and distancing from the emotional intensity and complexity of contact, but that in itself leaves unclear what role fearfulness actually played in the encounters.  相似文献
