Psychroptilus burrettae gen. et sp. nov., from the Late Carboniferous of Tasmania, combines characters of the insect orders Palaeodictyoptera and Megasecoptera. Psychroptilus is referred to the Megasecoptera because it lacks paratergal processes on the pronotum, and because its wing venation is simple, with reduced cross veins. However, its wings are not narrowed at their bases, but are as broad as those of the Palaeodictyoptera. It is placed in a new suborder of the Megasecoptera, the Neosecoptera. This suborder differs from the Suborders Eumegasecoptera and Protohymenoptera in having: 1, broad wings that are not narrowed at base; 2, the hind wing slightly broader than the fore wing; and 3, anal veins that all arise from close to the wing base. The insect is possibly the oldest recorded in the southern hemisphere although age determinations of this and the only other known probable Late Carboniferous species, Hadentomoides dwykensis Riek, are not precise. The inclusion of the insect fossil in varve-like sediments and the very few associated fossil species, are indicative of a very cold habitat either at or adjacent to the area producing the sediments. The great majority of insect fossils are associated with abundant plant remains or other fossils indicative of warm conditions in the area of sedimentation. None is recorded from an area apparently as cold as that under which Psychroptilus burrettae was preserved.  相似文献

Terrestrial reptile remains are very rare in the Lower Cretaceous of South Australia, but include the holotype of the small theropod Kakuru. Here, we review this taxon and other archosaur specimens collected from the Bulldog Shale (Aptian) of Andamooka and Coober Pedy. Kakuru possesses no unique characters or character state combinations and is regarded as a nomen dubium, representing an indeterminate tetanuran theropod. Two other specimens (a left metatarsal and astragalus) can be referred to Dinosauria, but the identity of several other specimens (phalanges and a centrum) can only be resolved to the level of an indeterminate archosaur.  相似文献

A new sthenurine taxon, Rhizosthenurus flanneryi gen. et sp. nov. from middle late Miocene deposits of Riversleigh, northwestern Queensland, is established on the basis of material previously assigned to Bulungamayinae. Postcranial remains belonging to an indeterminate basal macropodid are described. Cladistic analysis of 50 discrete postcranial characters coded for 16 ingroup and two outgroup taxa suggests that R. flanneryi is the most plesiomorphic member of a clade containing the late Miocene macropodid Hadronomas puckridgi and crown-group sthenurines. The indeterminate basal macropodid is placed as the immediate sister taxon to the bulungamayine Ganguroo bilamina and a monophyletic clade containing macropodines and sthenurines. This arrangement supports consideration of bulungamayines as ancestral to other macropodids and suggests that macropodines and sthenurines are monophyletic. However, the possibility of a diphyletic origin for Macropodinae and Sthenurinae from within Bulungamayinae cannot be dismissed.  相似文献

This article establishes that the suffering of the other represents a serious philosophical and ethical problem in Beauvoir's first post–World War II novel. In fact, the other's suffering poses such a complex problem in Le sang des autres particularly because Beauvoir depicts her characters’ world as a kind of Mitsein, which is Heidegger's word to describe how our lives necessarily intertwine with and envelop the lives of others while still allowing for the existential experience of separation. In the novel, the main characters’ potential responses to the other's suffering—quietism, indifference, charity, and empathy—fail according to the novel's existentialist ethical framework because of the ways these responses deny the fundamental ambiguity of Beauvoirian Mitsein. Only in accepting separation and connection as codependent ethical values do the characters find an ethically palatable response to the other's suffering at the end of the novel.  相似文献

The first caviine rodent referable to Galea Meyen, 1832 is described from the late Pleistocene of southern Brazil based on a left dentary with the p4–m3 series. The specimen derives from the Ponte Velha I locality in the Touro Passo Creek (Touro Passo Formation, upper Pleistocene), western Rio Grande do Sul State. The main characters used to assign this specimen to Galea are: anterior area of horizontal crest at the level of prism I of p4; deep anterior area of masseteric fossa; incisor alveolus on the medial face of the dentary extended up to the level of prism II of m2; and presence of cement in the hypoflexid. Currently, the genus has a disjunct distribution, with a group in Argentina, Bolivia and Peru, and another in northern and northeastern Brazil. The presence of this taxon in Pleistocene deposits of Rio Grande do Sul State, Uruguay and the Argentine Mesopotamian, where there are no extant representatives of the genus, indicates its wider distribution during the late Pleistocene.  相似文献

As an acclaimed work of twentieth-century Persian fiction, Sadeq Hedayat's The Blind Owl has stirred much scholarly contemplation. Identical characters obscure the work; the resemblance amongst them seemingly originates in some mysterious old man. The paper first demonstrates how every male character resembles this old man. Thereafter, he is argued to be non-existent; all the characters, therefore, become Baudrillardian simulacra bound together through family resemblances. A language-game is then fashioned to represent the family. The metamorphosis of the narrator is followed to manifest how this language-game haunts the characters—other language-games. The paper hopefully sheds some light on an ambiguous aspect of the work and provides a model as to how one language-game takes over another.  相似文献

This is a study of the Sanguo yanyi (hereafter Yanyi), one of the four great literary classics of China, in terms of its political standpoint, character evaluation, and character development. It questions the traditional views related to Yanyi’s stance of revering Liu Bei 劉備 and belittling Cao Cao 曹操. The argument here is that the novel's political standpoint is mainly based on zhongyi 忠義 (loyalty and righteousness), rather than lineage, benevolence, and other factors. Although Yanyi has a clear political position, it is relatively objective and neutral in evaluating historical figures from different camps. The character development of Yanyi is very successful. The character images are round and rich, rather than flat and stereotypical. Both positive and negative characters have their merits and weaknesses.  相似文献

Palygorskite is a rare clay mineral used by the ancient Mayas for fabricating the Maya blue pigment and for other purposes. It seems to have been obtained from a restricted area in the Yucatán peninsula where important archaeological sites are found. Geological samples from different localities in this area show a high content in palygorskite, indicating that this clay is widespread in Yucatán. Combining structural, morphological, compositional and geochemical methods, we analysed the common characteristics of Yucatecan palygorskites, and compared them with palygorskites from other origins around the world. These results can be used for defining a fingerprint of Yucatecan palygorskite to be used in provenance studies of archaeological artefacts, in particular the Maya blue pigment.  相似文献

从提点刑狱司制度看宋代“路”之性质   总被引:1,自引:1,他引:0  
提点刑狱司是宋朝首创的专门化的路级司法、监察机构。是继转运司后设立的又一个对州县进行监管的重要路级机构。从提刑司制度所反映出的宋代路级机构某些共性的特征来看:它们具有较固定的行政管理区划,处于地方一定的行政管理层级之中,有大量的行政处置权力。因而宋代的"路",尤其伴随着中央下放除监察权外的大量行政权力到转运、提刑等机构之后,可以被认定为是州县之上的一级正式行政管理层级和行政区划。宋代的"路"是一种权力多源化、分权制衡、集权于中央的新型地方行政体制,是宋代政治精英们对中国古代地方行政制度建设所做出的创新和贡献。  相似文献

This article approaches Chilean filmmaker Alicia Scherson’s first feature-length film, Play (2005), from the perspectives of mobility and social cartography in relation to the spatial practices of the main characters. Through the paradigmatic figure of the flâneur, the article explores the representative function of both the characters’ and the camera’s drifting itineraries across the city, as they subtly perform a peripatetic cartography of present-day Santiago. The diegetic threads that are spun by the characters progressively interlace to weave an urban text which lays bare – as they are transgressed – a series of frontiers that cut across the cityscape. The film maps out two very different human geographies of post-dictatorship Chile, a lived urban space that reveals the stark social divide propping up the nation’s neoliberal economic structure. Scherson’s roving camera engages in a politics of perception which invites the spectator to view the city differently, thus exploring the possibility of upsetting this divide.  相似文献

The state of a group of glaciers in the northern Mackenzie Mountains across the Yukon‐Northwest Territories border was investigated over a period of three decades, using Landsat TM and OLI imagery from 1987, 1994, 1999, 2004, 2013, and 2017 to examine changes in glacier extents. A thresholded red/shortwave infrared band ratio image was used to delineate glacier boundaries. The total area of 74 glaciers in the study area decreased from 52.78 ± 1.32 km2 in 1987 to 24.89 ± 0.62 km2 in 2017, a loss of 27.89 ± 1.39 km2 or 52.8 ± 2.6%, with a mean rate of reduction of 1.8% · a?1. Smaller glaciers experienced larger relative changes in area. In this study, the rates of reduction are high compared to decreases reported for other glaciers in the region in the late 20th century. Based on linear extrapolation of the trend in values of total glacier area, it is predicted—subject to uncertainties in how glaciers diminish in size and eventually disappear—that the study area could be free of visible glacier cover within three decades.  相似文献

The anatomy of a new articulated enantiornithine bird skeleton from the Late Cretaceous of Patagonia clearly indicates a capacity for powered flight, approaching that of modern birds. Enantiornithines possess some of the synapomorphies of the Ornithurae, although they retain plesiomorphic states for many other characters, mainly in the hind limb. Such a mosaic character combination suggests a sister-group relationship between Enantiornithes and Ornithurae. Derived features of the pectoral girdle are here considered as diagnostic for a major avian clade, the Ornithopectae, comprising all known birds other than Archaeopteryx. The combination of derived and primitive traits in the fore and hind limbs and their girdles in early ornithopectines reflects mosaic evolution, with flight-related modifications of the fore limb and pectoral girdle preceding those in the hind limb and pelvic girdle.  相似文献

This article examines the Vita Gangulfi prima, a text which was frequently copied and widely circulated in the Middle Ages. It argues that the text can be understood as an ironic discourse on miracle stories in hagiographical texts: the central message of the Vita is that meek and penitential living leads to sanctity, and not the enjoyment of stories about miracles. At the same time, the Vita presents the reader to some extent with a performance of this idea. The reader who sees through to the Vita's ironic intent is encouraged to laugh at the saint and thereby comes to comprehend the very sin for which the various characters in the Vita are punished, while the text simultaneously depicts penitence as the way out of this sinfulness. The Vita's critique of miracle stories made an eccentric contribution to a discourse which was also carried on in a number of other hagiographical texts of the early tenth century.  相似文献

This paper discusses Mary Lavin's place within the Irish literary tradition by means of an analysis of her representations of female characters. It argues, first, that Lavin's short stories depart from the short story tradition in general and the Irish short story tradition in particular by failing to subscribe to the cultivation of the romantic outsider and focusing instead on family relations and social responsibilities. Second, Mary Lavin's marginal position in a feminist or female literary tradition is explained through her unwillingness to portray women as victims and through the absence of a clear critique of patriarchy in her work. The paper then tries to characterise the relationship between individual and society in Lavin's short fiction in a more positive way, by focusing on the notions of individual fate and personal responsibility, which turn out to be crucial to Mary Lavin's philosophy. This philosophy is first discussed explicitly in a reading of the story ‘Happiness’ and ‘The Widow's Son’ and subsequently shown to lie behind the oppositions and dilemmas in several other stories. Finally, the article demonstrates how Lavin manages to realise her Nietzschean belief in an Amor Fati in some of her most positive female characters through a clever use of imagery and point of view, without thereby succumbing to sentimentality or cliché.  相似文献

Wang, Y., Shih, C., Szwedo, J. &; Ren, D. iFirst article. New fossil palaeontinids (Hemiptera, Cicadomorpha, Palaeontinidae) from the Middle Jurassic of Daohugou, China. Alcheringa, 1–12. ISSN 0311-5518.

A new genus and species assigned to the extinct family Palaeontinidae, Synapocossus sciacchitanoae Wang, Shih &; Ren, is described from the Middle Jurassic of Daohugou in Inner Mongolia, China. This new genus is established based on well-preserved fossil specimens with body and complete forewings and hind wings. It differs from other described genera by the following characters: small body size, RP and M1 coalescing for an interval on the forewings and M3 + 4 without bifurcation on the hind wings. The RP coalescence with M1 in Synapocossus Wang, Shih &; Ren previously reported only in Turgaiella Becker-Migdisova &; Wootton, seems to be associated with strengthening of the anterior wing margin. The intra-specific and individual variations of Synapocossus and numerous other insect fossils of northeastern China probably indicate long-lasting ecological stresses and a competitive environment in the Middle Jurassic to Early Cretaceous ecosystems.  相似文献

This paper presents the results of the archaeometric study of 30 grinding tools found in the Karst plateau (an area that spreads from the northeastern border of Italy to Slovenia) and in the Istria peninsula (Croatia). The petrographic and geochemical characteristics of the artefacts indicate that most of them would be made of trachytic volcanites extracted from the Euganean Hills, near Padua (Veneto). It is known that trachytic rocks from this area had been widely exploited in northern Italy during protohistoric times, but these data considerably enlarge the area of diffusion of saddle‐querns made of these rocks, extending it to Istria. Additionally, the likely provenance from Mount Etna of few other pieces of mugearites and hawaiites represents a new element, to be fully evaluated in the context of trans‐Adriatic exchange/trade connections. Analytical data and possible archaeological inferences are presented in detail in the text.  相似文献

Robert McLiam Wilson has become one of the most influential literary voices to emerge from Northern Ireland since the Troubles began, and he has challenged the understanding of contemporary Irishness. His novels are gritty, acerbic and he constructs images of Belfast that are as startling as they are affectionate. Both Ripley Bogle (1989) and Eureka Street (1996) involve characters from broken families who, in spite of sectarian violence around them, find emotional support from unlikely individuals. Failure of parenting is a persistent motif in McLiam Wilson, but so too is the triumph of love because the protagonists of Ripley Bogle and Eureka Street both turn to unlikely individuals for guidance. Although traditional parenting fails, pseudo-adoptive parents mollify both Ripley Bogle and Jake Jackson by granting them support and love.  相似文献

This article presents excerpts from two near-contemporary works of popular prose from the medieval Near East: the Persian Dārāb-nāmeh and the Arabic Sīrat Banī Hilāl. In each, birds or birdlike characters (the sīmorgh and the crow, respectively) that share in having had theriomorphic, mythic significance in regional pre-Islamic traditions dispense premonitory wisdom to Muslim characters. Comparing these passages, the article contends that the characterization of these birds brokers a pietistic shift in symbolism between the pre-Islamic and Islamic context, while still maintaining the birds’ mystical significance and sustaining the trope of birds as winged, heaven-sent messengers. This modified association between birds and divine ministry is not only prominent in these two texts, but also in the Qur?ān and varied bestiaries, poetry, and belletristic works that comprise these texts’ cultural network.  相似文献
