A diverse and well-preserved fossil wood assemblage is described, for the first time, from the Middle Permian Taerlang Formation and the Upper Permian Quanzijie Formation in the vicinity of the Tianshan Town, Hami City of northwestern China. On the basis of wood microstructure, the fossil woods are classified into three genera and five species, including one new genus: Prototianshanoxylon gen. nov. and two new species: Prototianshanoxylon erdaogouense sp. nov., Prototianshanoxylon hamiense sp. nov. The new genus is characterized by window-like cross-field pitting and mixed tracheid radial wall pitting that suggest a transitional type between araucarioid-type and protopinoid-type pittings.Phytogeographically, the fossil wood assemblage is characterized by an admixture of elements of both temperate Angaran (represented by wood specimens with moderately to well defined growth rings in their secondary xylem) and tropical-subtropical north subregion of the Cathaysian floras (with wood specimens lacking well-defined growth rings). Such a phytogeographically mixed fossil wood assemblage is interpreted to represent a transitional and complex climate condition between a cool temperate and tropical to subtropical zones, showing both seasonal variation and unstable climate conditions. Previously, similarly mixed floras have already been found to exist widely in northern China ranging in age from Early to Late Permian, but the mechanisms thought to be responsible for their formation were varied and remain controversial. In this study, the formation of these mixed Permian floras of North China is linked to the closure of the Tianshan-Hingan seaway coupled with the collision and amalgamation of Siberia with North China and the Tarim block, in a manner much like closing a pair of scissors with the closure of the seaway proceeding gradually and progressively from west to the east.

The rising expectations of university students with regard to quality, service and value for money, and the growing diversity of student populations have challenged universities to become increasingly student focused. Marketing theory suggests that a clear understanding of customer needs and expectations is central to being customer focused and to facilitate targeting of products and services to appropriate segments. The process requires the marketer to have insights into the cultural backgrounds of customers where the study of personal values becomes a critical component in understanding consumer needs and preferences. The results of this study indicate that personal values are useful in explaining differences amongst the student cohorts with regard to age, gender and nationality. Recommendations are made with regard to developing the educational product for the international student, based on underlying value domains of Self-efficacy and Hedonism.

Isogramma manchoukuoensis from the Upper Carboniferous of northeast China is redefined based on re-examination of the type specimens. Isogramma specimens from the Middle Permian of northeastern Japan are reassigned to I. aff. paotechowensis. A new family, Schizopleuroniidae, is proposed to include Schizopleuronia, but excludes Megapleuronia, which belongs to the Megapleuroniidae Liao, 1983. The family Isogrammidae is considered to be a transitional group in the eichwaldid-isogrammid-schizopleuronid evolutionary lineage within the Dictyonellida. A review of the global distribution of Isogramma species reveals that the genus has a total of 56 species ranging from the Mississippian (Early Carboniferous) to the Lopingian (Late Permian). Isogramma diversified rapidly after its origination in the middle Viséan and its species diversity remained high throughout the Mississippian. The genus possibly suffered a severe mid-Carboniferous boundary mass extinction, with no Early Carboniferous species surviving this event. Bashkirian Isogramma species show low diversity, followed by a global recovery in the Moscovian. During the latest Carboniferous Isogramma became highly diversified again. At the Carboniferous–Permian (C/P) transition Isogramma underwent another dramatic diversity drop, followed by several stepwise declines in diversity during the Early–Middle Permian. The Wuchiapingian I. sinosa is the last Isogramma species.

Ukraine was the possible centre of origin for Isogramma. From Ukraine Isogramma spread over the Moscow Basin of Russia, Central Europe (Germany, Austria), South Europe (Spain) and West Europe (England, Ireland and Scotland), and migrated to the North American midcontinent and South China during the late Viséan (Early Carboniferous). In Europe, Isogramma migrated to Spain and eastern Europe (Serbia) in the Moscovian, from there it then dispersed into Central Asia (Uzbekistan and Kazakhstan) in the Kasimovian-Gzhelian. In the Palaeo-Tethys Isogramma migrated from South China to northeast and northwest China in the Moscovian, spread over the North China Block during the C/P transition, moved to Russian Siberia, Japan and the Qiangtang terrane of the Palaeo-Tethys during the Early–Late Permian. In North America Isogramma spread over the midcontinent during the Late Carboniferous and Early–Middle Permian and migrated to South America (Bolivia) in latest Carboniferous. Biogeographically, Isogramma was confined principally to the palaeo-tropical and warm to temperate zones throughout the Late Palaeozoic, with the possible exception of the Artinskian, as a questionable species of the genus also occurs in the Transbaikal region of southeast Russia.

The temples of Southeast Asia are remarkable and intriguing in their architecture, in that they are obviously derivative from Indic canon and yet
profoundly original and different from the corpus of the subcontinent. Further, the regional nuances of these temples, whether in Java, Cambodia or Champa, defy obvious and linear connections within these traditions and with the pan-Indic corpus. While epigraphists, Sanskritists and historians have made significant connections between these temple building traditions, much work remains to be done on the compositional and architectural linkages along the trading routes of South and Southeast Asia. This paper is an early attempt at understanding the compositional connections, as evident in the temple forms of early southeast Asia. To elucidate the complex material, the authors deploy a comparative method on two levels. Between ideal notions of the Hindu temple and shared cosmogony on one hand and individual temples as a realization of the ideal on the other. The consideration of the compositional material yields some surprisingly rich and varied connections. For example, the affinities between 7th century cellas in Cambodia and early Gupta models from central India are difficult to ignore. Further, the linkages between these cellas and the early Deccan experiments in structural stone raise questions about both idioms. The range of experimentation in Cambodia
(in plan forms, superstructure and construction methods are discussed with reference to their Indic antecedents. The findings of the paper raise questions about the relation between temple and treatise; between theory and practice and between the individual temple and its collective corpus.

This study examines the impact of Asian financial crisis on central bank independence and governance in the Asia Pacific. It applies a unique CBIG index-model for 36 countries for the period 1991 to 2005. This paper examines changes in the CBIG in the Asia Pacific before and after the Asian financial crisis in 1997. It applies a panel data pooled regression model and finds that the Asian financial crisis dummy is significantly different in the post-crisis period compared to the pre-crisis period. As a result the improved CBIG in the post-crisis period has contributed to lower the inflation in the entire region.

The expansion of private forestry and the partnership between government and private sector timber growers and processors highlights the issues associated with a functionally based rather than a place based approaches to changing patterns of land use in rural areas. Rural development through blue gum forestry was promoted as a means of revitalising rural communities, providing both economic and social gains to regional areas. The purpose of this study is to examine the economic consequences of policies designed to promote plantation forestry at a local level. It concludes that while plantation forestry may bring benefits to the national economy, these benefits may not be apparent at a local level especially if the industry operates in competition with a viable alternative.

Background: Physical activity (PA) surveillance is an important component of non-communicable disease risk factor monitoring, and occurs through national and international surveillance systems. This review identifies population PA estimates for adults in the Asia-Pacific region, and examines variation in trends and prevalence rates obtained using different PA measures.

Methods: Data were obtained from a MEDLINE search; World Health Organization’s Global Health Infobase; Government websites and reference lists of relevant papers. Inclusion criteria included: national studies or those reporting large scale population-level data; data published from 2000 to 2010 and trend data prior; sample sizes over n = 1000, or fewer subjects in small nations.

Results: In total, 56 population surveys from 29 Asia-Pacific countries were identified. Data on ‘sufficient physical activity’ amongst adults were available from 45 studies (80%), with estimates ranging from 7% to 93% (median 62%, inter-quartile range 40%-85%). For 14 countries, estimates of ‘sufficient activity’ were documented in multiple surveys using different methods, with the largest variation from 18% to 92% in Nepal. Median or mean METminutes/ day, reported in 20 studies, ranged from 6 to 1356. Serial trend data were available for 11 countries (22%), for periods spanning 2-10 years. Of these, five countries demonstrated increases in physical activity over time, four demonstrated decreases and three showed no changes.

Conclusions: Many countries in the Asia-Pacific region collect population-level PA data. This review highlights differences in estimates within and between countries. Some differences may be real, others due to variation in the PA questions asked and survey methods used. Use of standardized protocols and measures, and combined reporting of data are essential goals of improved international PA surveillance.

Over the last century and a half the competing merits of withdrawal from and connection to Asia-and the related vocabularies of separation and engagement-have been defining themes in Australian history. Experiencing Turbulence brings together a selection of publications on Australian representation of Asia, published in various journals and books in the last ten years that follow the publication of Anxious Nation: Australia and the Rise of Asia, 1850 to 1939. Collectively they address key themes in the Australian response to Asia: survivalist anxieties, climate and race, population and immigration, empty Australia, gender and bush mythologies, and regional Identities. These essays reveal the central, often constitutive role that Asia has played in the formation of ideas of nation and identity in Australia from the late nineteenth century to the present. The collection underlines the often unpredictable character of engagement and the fluid nature of fear and fascination, proximity and distance in the Australia-Asia relationship. With the recent publication of a government White Paper on Australia in the Asian Century there is a new determination to persuade Australians that "rising Asia," turbulent though it may be, is an opportunity for Australia more than it is a threat.

 This paper examines assumptions about democracy and the role of media held by journalism educators working outside Australia, and the extent to which those assumptions influence teaching styles, regardless of the maturity of the political systems in the nations in question. This paper looks at the work emerging from academics Beate Josephi, Barbie Zelizer, John Nerone, Cherian George and Silvio Waisbord, who argue in Journalism (2012) that there needs to be a change to the understanding by journalism scholars of the central place of journalism in democracy because that view is not global in its perspective. This paper specifically considers Zelizer’s point that “much of the scholarly world in the West – and specifically in the United States – depends directly or indirectly on the presumption of democracy and its accoutrements”. The researcher asks, “what can we learn about our Australian perspective on teaching journalism in the developing world where there may not, yet, be an operating democracy or a form of democracy that replicates the Western liberal model?”

A Kubergandian (Kungurian) fusuline fauna from the lower part of the Lugu Formation in the Cuozheqiangma area, central Qiangtang Block is described. This fusuline fauna belongs to the Southern Transitional Zone in palaeobiogeography, and is characterised by the presence of the distinctive bi-temperate genus Monodiexodina and many genera common in lower latitude Tethyan areas such as Parafusulina and Pseudodoliolina. The occurrence of Monodiexodina in the fauna confirms that the seamount-type carbonates of the Lugu Formation did not originate from the Palaeotethys Ocean, but rather from a branch of the Neotethys Ocean after the rifting of the Qiangtang Block from the Tethys Himalaya area in the Artinskian. © 2014 Geological Society of China.
