A biogeographically mixed, Middle Permian brachiopod fauna from the Baoshan Block, Western Yunnan, China

A small brachiopod fauna is described from the carbonate rocks of the basal Shazipo Formation of the Baoshan Block, western Yunnan, south-west China, including significant new ventral and dorsal internal morphological features of Cryptospirifer omeishanensis Huang. This fauna is regarded as Wordian (Middle Guadalupian, Middle Permian) because of the presence of Cryptospirifer omeishanensis Huang and associated fusulinids (Neoschwagerina craticulifera Zone). Palaeobiogeographically, the brachiopod fauna is of considerable interest because of its admixed nature characterized by typical warm-water Cathaysian elements intermingled with temperate Peri-Gondwanan taxa. This in turn is interpreted to indicate that the Baoshan Block may have been situated in an intermediate palaeogeographical position between Gondwanaland to the south and Cathaysia to the north during the Mid Permian and, as such, it probably furnished an important 'stepping stone' for the dispersal of Mid Permian eastern Tethyan marine invertebrate taxa (e.g. Cryptospirifer) to the western Tethys.

Art, pain, children: utopian and dystopian discourses in picture books

It is often assumed that picture books are intended for young children and that they are therefore mainly concerned with safe and reassuring stories, say, about home and family, friends and starting school. There are many picture books which fit within this category, but the form itself, a 32-page format which developed during the 1960s from illustrated books, has always been peculiarly open to experimentation and has enlarged its audience to include older children and adults. Unlike the novel, the picture book is not weighed down by the practices and conventions of the past; and the combination of verbal and visual texts makes for a particularly complex genre as it constructs ideas through dialogical relations between words and pictures.

Early carboniferous brachiopod faunas from the Baoshan block, west Yunnan, southwest China

38 brachiopod species in 27 genera and subgenera are described from the Yudong Formation in the Shidian-Baoshan area, west Yunnan, southwest China. New taxa include two new subgenera: Unispirifer (Septimispirifer) and Brachythyrina (Longathyrina), and seven new species: Eomarginifera yunnanensis, Marginatia cylindrica, Unispirifer (Unispirifer) xiangshanensis, Unispirifer (Septimispirifer) wafangjieensis, Brachythyrina (Brachythyrina) transversa, Brachythyrina (Longathyrina) baoshanensis, and Girtyella wafangjieensis. Based on the described material and constraints from associated coral and conodont faunas, the age of the brachiopod fauna from the Yudon Formation is considered late Tournaisian (Early Carboniferous), with a possibility extending into earlyViseacutean.

They went home: racialised spaces in contemporary picture books

This paper discusses Michel de Certeau’s theories of spatialised power and of resistance, especially his characterisation of what he describes as ‘tactics’ by which marginalised groups resist the strategies by which those in power gain and maintain control, in relation to a group of settler society picture books: Edna Tantjingu Williams, Eileen Wani Wingfield and Kunyi June-Anne McInerney’s Down the hole (2000); the Papunya School Book of Country and History (2001); Chiori Santiago and Judith Lowry’s Home to Medicine Mountain (1998); George Littlechild’s This Land Is My Land (1993); and Allen Say’s Home of the Brave (2002). These texts thematise colonial and assimilationist policies in Australia, Canada and the United States which required that racialised groups of children should be removed from their homes and families and placed in institutions. I argue that the first four of these texts position child readers both to understand the dislocation and pain caused by government policies such as those which enforced the removal of the Stolen Generation in Australia, and to appreciate the tactics of resistance by which children evaded or subverted institutional power. Home of the Brave deploys the symbolism of an adult’s journey into the past to show how strategies of repression serve to protect individuals and nations from shame and guilt, and demonstrates the transformative effects which result when the past is scrutinized.

Phase behavior and crystallization in blends of a low molecular weight polyethylene-block-poly(ethylene oxide) diblock copolymer and poly(hydroxyether of bisphenol A)

The phase behavior, morphology and crystallization in blends of a low-molecular-weight (Mn = 1400) double-crystalline polyethylene-block-poly(ethylene oxide) (PE-PEO) diblock copolymer with poly(hydroxyether of bisphenol A) (PH) were investigated by differential scanning calorimetry, transmission electron microscopy and small-angle X-ray scattering. The symmetric PE-PEO diblock copolymer consists of a PH-miscible PEO block and a PH-immiscible PE block. However, PH only exhibits partial miscibility with the PEO block of the copolymer in the PH/PE-PEO blends; both macrophase and microphase separations took place. There existed two macrophases in the PH/PE-PEO blends, i.e., a PH-rich phase and a PE-PEO copolymer-rich phase. The PE block of the copolymer in the blends exhibited fractionated crystallization behavior by homogeneous nucleation. There appeared three crystallization exotherms related to the crystallization of the PE block within three different microenvironments in the PH/PE-PEO blends.

Identity territory: Pamela Allen's picture books in the Australian psyche

Parsons examines the dialogic space of the picture book reading, and its co-opting of the authority of the "significant other" in relation to Pamela Allen's picture books. Mapping Australian identity theory in Allen's picture books involves recognizing Australian-ness as both formed and performed at a point of intersection between colonial, migrant, and patriarchal tropes. Each of these tropes is readable through the dynamics of theater semiotics, and each is mirrored by child maturation as embodied by a movement toward adult authority.
