The present study examined children's perceptions of other children's ability to make moral judgements. Preschool, kindergarten, first- and second-grade children rated the permissibility of moral transgressions for a same-age peer, a younger child and an older child. Children also were asked why the transgressions were wrong. Preschool and kindergarten children rated transgressions equally wrong for a same-age peer, a younger and an older child, whereas first and second graders rated transgressions for a same-age peer and an older child as more wrong than for a younger child. Preschoolers stated they did not know why the transgressions were wrong for a younger child, while kindergarten children reasoned that a younger child did not know the rules. First and second graders reasoned that a same-age peer and an older child should know ‘better’, but a younger child would not know ‘better’. Results suggest that children's perceptions of others' moral knowledge is related to children's ability to coordinate domains of social knowledge when making judgements of others' moral transgressions.  相似文献

The Capitanian (Late Guadalupian) Maokou Formation at Chaotian in northern Sichuan, South China, is composed mainly of shallow marine shelf carbonates deposited on the Tethyan side of South China. By detailed field mapping and scientific drilling, we newly found out unique fossil assemblages and a sharp lithologic change in the upper part of the Maokou Formation. The main part of the Maokou Formation (over 130 m thick) is composed of algal packstone with Wordian-Capitanian large-tested fusulines, rugose corals and other sessile benthos, whereas the Uppermost Member (13 m thick) is composed of black limy mudstone/chert with Capitanian offshore biota (ammonoids, radiolarians, and conodonts). The topmost Capitanian conodont zones are missing; however, the Maokou Formation is disconformably overlain by 260+/-4 Ma volcanic ash (Wangpo bed) and the Early Lopingian Wujiaping Formation with plant-bearing coaly mudstone and shallow marine carbonates (packstone). The newly identified facies change indicates that northern Sichuan has experienced rapid sea-level changes in the late Guadalupian, i.e., first a transgression in the mid-Capitanian and then a regression across the Guadalupian-Lopingian boundary. As the end-Guadalupian is characterized by a global regression, such a volatile sea-level fluctuation, in particular the sea-level rise, is unique to the Tethyan side of South China. The newly recognized relatively deep-water late Guadalupian sequence adds new paleo-environmental information and further provides a paleotectonic interpretation of the low-latitude eastern Tethyan margin immediately before the end-Guadalupian mass extinction.  相似文献

Several traces of biological interaction were found on penguin bones from the basal levels (Aquitanian) of the Miocene Gaiman Formation in the lower Chubut valley of the Provincia del Chubut, Argentina. The fossil-bearing beds were deposited in littoral to sublittoral environments within sediments of mostly pyroclastic origin. We interpret many traces to have been produced by predators and/or scavengers while the penguins were still in a breeding area. Many bones show cracking marks due to aerial exposure. The material is disarticulated as is usual in recent breeding areas. Potential predators were coeval terrestrial mammals, most probably marsupial carnivores. After a marine transgression, these bones were buried or exposed on the sea bottom where they could be colonized by algae, sponges, cnidarians, and other benthic organisms. We identified sponge borings in several bones. Other traces are interpreted to have been produced by echinoderms feeding on sponges or algae. No evidence of other invertebrate predators such as muricid or naticid gastropods, or decapods was found. Finally, other traces appear to have been generated by shark and possibly teleostean vertebrates feeding on epibionts. One coracoid is interpreted to have been marked by a shark that is common in the Gaiman Formation, the carcharhiniform Galeocerdo aduncus. From an ethological (Seilacherian) classification, traces on bones from the Gaiman Formation include Domichnia (sponge perforations), Praedichnia (terrestrial marsupials, sharks, teleosteans) and Pasichnia (echinoderms). Remarkably, remains of marine organisms with skeletons made of calcium carbonate are very poorly preserved in the Gaiman Formation. Only large oysters, sparse shell fragments, skeletal moulds, and bioturbation is evident. The fossil assemblage is mainly composed of phosphatic (e.g. teeth, bones, crustacean parts) and siliceous (sponge spicules, diatoms) remains.  相似文献

Ongoing human–long-tailed macaque (Macaca fascicularis) conflicts in Bukit Timah Nature Reserve, Singapore, have seen native macaques significantly affected, as residential development encroaches into animals' habitat, destroying important wildlife corridors. The search for a more humane treatment of these transgressive animals can be seen as an attempt to extend and include non-human animals within humanistic notions of ethics and care, in the process destabilizing the assumed divide between human/animal. Yet, a feasible solution is difficult to reach as National Parks Board (NParks), the state agency overseeing the conservation of reserves and wildlife, has to negotiate constantly between their goal of maintaining biodiversity and appeasing the complaining residents. The paper seek to understand urban–wilderness conflicts between human–macaque, showing that the divide between tamed/wild is multi-sited, ambiguous and constantly shifting. In this regard, we are especially interested in the role of intermediaries in initiating actions to ‘make discursive as well as material space’ for macaques in the reserve. Intermediaries, here referring to NParks and animal activists, are actors who do not reside near the reserve thus having no frequent encounters with wildlife, yet are enrolled as mitigators during instances of human–animal conflicts.  相似文献

Transgression is not only an inevitable part of systemic supervision but is also necessary if we are to work towards innovative and inclusive supervisory and therapeutic practice. Defying culturally generated ‘rules’ of systemic practice can allow for more relevant and productive ways of talking. Systemic practitioners are increasingly finding themselves trying to practice systemic therapy in employing authorities and training courses which are dominated by inflexible professional narratives and manualised procedures. Our profession is committed to ethical inner and outer dialogue, to self‐ and relational reflexivity as distinct from the rule‐bound surveillance culture in which we live and work. Systemic supervisors and therapists may find themselves at odds with monological institutional discourse and attempts from within our own profession to manualise practice. I introduce examples from supervisory conversations to illustrate how supervisors can develop more culturally sensitive practices through supporting practitioners to hear and have heard their own marginalised and oppressed voices and those of their clients.  相似文献

The discovery of a previously unrecognized unconformity and of new faunas in the type Llandovery area underpins a revised correlation of Hirnantian strata in mid Wales. This has revealed the sedimentary and faunal events which affected the Lower Palaeozoic Welsh Basin during the global rise in sea level that followed the end‐Ordovician glacial maximum and has allowed their interpretation in the context of local and global influences. In peri‐basinal shelfal settings the onset of post‐glacial deepening is recorded by an unfossiliferous, transgressive shoreface sequence (Cwm Clyd Sandstone and Garth House formations) which rests unconformably on Rawtheyan rocks, deformed during an episode of pre‐Hirnantian tectonism. In the deep water facies of the basin centre, this same sequence boundary is now recognized as the contact between fine‐grained, re‐sedimented mudstones and an underlying regressive sequence of turbidite sandstones and conglomerates; it is at a level lower than previously cited and calls into question the established lithostratigraphy. In younger Hirnantian strata, graptolites associated with the newly recognized Ystradwalter Member (Chwefri Formation) demonstrate that this distal shelf unit correlates with the persculptus graptolite‐bearing Mottled Mudstone Member of the basinal succession. Together these members record an important macrofaunal recolonization of the Welsh Basin and mark a key event in the post‐glacial transgression. Further deepening saw the establishment of a stratified water column and the imposition of anoxic bottom water conditions across the basin floor. These post‐glacial Hirnantian events are consistent with the re‐establishment of connections between a silled Welsh Basin and the open Iapetus Ocean. However, a comparison with other areas suggests that each event records a separate deepening episode within a pulsed glacio‐eustatic transgression, while also reflecting changes in post‐glacial climate and patterns of oceanic circulation and associated biotic flux.

福建东南沿海第四纪盆地构造沉降   总被引:1,自引:0,他引:1       下载免费PDF全文
利用福建东南沿海地区城市活断层探测的研究资料,重新确认了福州、泉州和漳州盆地的断层组合与第四纪沉积。研究区内晚更新世“福州海侵”产生的炭质淤泥沉积现代高程的分析对比表明,晚更新世以来该区地壳发生不均匀隆升,而这些盆地相对于研究区内其他地区发生沉降。断层的静态位错理论研究认为,正断层深部活动引发地表的沉降,该区断裂的深部正断层活动是盆地沉降的重要因素。盆地的发展演化可划分为晚更新世以前的断陷阶段,和其间或其后的拗陷沉积阶段。  相似文献
