Graphene networks and their influence on free-volume properties of graphene-epoxidized natural rubber composites with a segregated structure: rheological and positron annihilation studies

Epoxidized natural rubber-graphene (ENR-GE) composites with segregated GE networks were successfully fabricated using the latex mixing combined in situ reduced technology. The rheological behavior and electrical conductivity of ENR-GE composites were investigated. At low frequencies, the storage modulus (G′) became frequency-independent suggesting a solid-like rheological behavior and the formation of GE networks. According to the percolation theory, the rheological threshold of ENR-GE composites was calculated to be 0.17 vol%, which was lower than the electrical threshold of 0.23 vol%. Both percolation thresholds depended on the evolution of the GE networks in the composites. At low GE concentrations (<0.17 vol%), GE existed as individual units, while a "polymer-bridged GE network" was constructed in the composites when GE concentrations exceeded 0.17 vol%. Finally, a "three-dimensional GE network" with percolation conductive paths was formed with a GE concentration of 0.23 vol%, where a remarkable increase in the conductivity of ENR-GE composites was observed. The effect of GE on the atom scale free-volume properties of composites was further studied by positron annihilation lifetime spectroscopy and positron age momentum correlation measurements. The motion of ENR chains was retarded by the geometric confinement of "GE networks", producing a high-density interfacial region in the vicinity of GE nanoplatelets, which led to a lower ortho-positronium lifetime intensity and smaller free-volume hole size.

Assessment of acute burn management in 32 low- and middle-income countries

BACKGROUND: The purpose of this study is to ascertain whether acute burn management (ABM) is available at health facilities in low- and middle-income countries (LMICs). METHOD: The study used the World Health Organization situational analysis tool (SAT) which is designed to assess emergency and essential surgical care and includes data points relevant to the acute management of burns. The SAT was available for 1413 health facilities in 59 countries. RESULTS: A majority (1036, 77.5 %) of the health facilities are able to perform ABM. The main reasons for the referral of ABM are lack of skills (53.4 %) and non-functioning equipment (52.2 %). Considering health centres and district/rural/community hospitals that referred due to lack of supplies/drugs and/or non-functioning equipment, almost half of the facilities were not able to provide continuous and consistent access to the equipment required either for resuscitation or to perform burn wound debridement. Out of the facilities that performed ABM, 379 (36.6 %) are capable of carrying out skin grafts and contracture release, which is indicative of their ability to manage full thickness burns. However the magnitude of full thickness burns managed was limited in half of these facilities, as they did not have access to a blood bank. CONCLUSION: The initial management of acute burns is generally available in LMICs, however it is constrained by the inability to perform resuscitation (19 %) and/or burn wound debridement (10 %). For more severe burns, an inability to perform skin grafting or contracture release limits definitive management of full thickness burns, whilst lack of availability to blood further compromises the treatment of major burns.

State identity in Iranian foreign policy

This article examines the role of corporate identity in Iran’s foreign policy making. Drawing on interviews with Iranian stakeholders and an analysis of Iran’s political developments, this article surveys the three key elements of Iranian nationalism that shape Iranian foreign policy: Iranism, Islam and Shi’ism. This article finds that each of these is crucial in explaining the apparent contradictions in the approaches of several significant Iranian leaders, especially in cases where Iranism collides with religious values. By highlighting how each component is at once unique but still intrinsically linked to the others, this article demonstrates how Iran’s foreign policy choices can be understood in relation to its corporate identity.

Bellwether procedures for monitoring and planning essential surgical care in low- and middle-income countries: caesarean delivery, laparotomy and treatment of open fractures

BACKGROUND: Surgical conditions represent a significant proportion of the global burden of disease, and therefore, surgery is an essential component of health systems. Achieving universal health coverage requires effective monitoring of access to surgery. However, there is no widely accepted standard for the required capabilities of a first-level hospital. We aimed to determine whether a group of operations could be used to describe the delivery of essential surgical care.

METHODS: We convened an expert panel to identify procedures that might indicate the presence of resources needed to treat an appropriate range of surgical conditions at first-level hospitals. Using data from the World Health Organization Emergency and Essential Surgical Care Global database, collected using the WHO Situational Analysis Tool (SAT), we analysed whether the ability to perform each of these procedures-which we term "bellwether procedures"-was associated with performing a full range of essential surgical procedures.

FINDINGS: The ability to perform caesarean delivery, laparotomy, and treatment of open fracture was closely associated with performing all obstetric, general, basic, emergency, and orthopaedic procedures (p < 0.001) in the population that responded to the WHO SAT Survey. Procedures including cleft lip, cataract, and neonatal surgery did not correlate with performing the bellwether procedures.

INTERPRETATION: Caesarean delivery, laparotomy, and treatment of open fractures should be standard procedures performed at first-level hospitals. With further validation in other populations, local managers and health ministries may find this useful as a benchmark for what first-level hospitals can and should be able to perform on a 24/7 basis in order to ensure delivery of emergency and essential surgical care to their population. Those procedures which did not correlate with the bellwether procedures can be referred to a specialized centre or collected for treatment by a visiting specialist team.

Re-thinking multiculturalism: performing the Cronulla beach riot

Since 11 September 2001, Australia’s race relations have been an issue of significant cultural concern, particularly relations between Anglo-Celtic and Middle-Eastern Australians. Riots on Cronulla Beach, Sydney, in December 2005 heightened this concern. This paper looks at the events at Cronulla and the debates they catalysed about race relations in Australia, and examines how these discourses have been shaped by arguments from both the Right and the Left. Informed by the discourse of critical multiculturalism, we examine several performance-based arts activities that made the riots their subject matter and argue that these arts practices reflect a larger cultural concern about the currency of traditional forms of multiculturalism, and promote instead an emphasis on understanding racial conflict as a critical negotiation over shared territories and values.

Celebrating difference

This thesis examines short fiction and some poetry by writers from four different Australian cultural communities, the Indigenous community, and the Jewish, Chinese and Middle-Eastern communities. I have chosen to study the most recent short fiction available from a selection of writing which originates from each culture. In the chapters on Chinese-Australian and Middle-Eastern Australian fiction I have examined some poetry if it contributes to the subject matter under discussion. In this study I show how the short story form is used as a platform for these writers to express views on their own cultures and on their identity within Australian society. Through a close examination of texts this study reveals the strategies by which many of these narratives provide an imaginative literary challenge to Anglo-Celtic cultural dominance, a challenge which contributes to the political nature of this writing and the shifting nature of the short story genre. This study shows that by celebrating difference these narratives can act as a site of resistance and show a capacity to reflect and instigate cultural change. This thesis examines the process by which these narratives create a dialogue between cultures and address the problems inherent in diverse cultural communities living together.

Resource use by the Eastern Grey Kangaroo and the Black Wallaby in a managed remnant woodland community

This work studies the interactions and relationships that exist between Eastern Grey Kangaroos and Black Wallabies in their utilisation of spatial and trophic resources in a managed remnant woodland community. The thesis provides a closer understanding of the way in which these species impact upon their habitats. The Coranderrk Reserve, near Healesville in eastern Victoria, Australia was the study site. A floristic analysis of the communities of the study site was conducted. This consisted of plant biomass measurements, estimates of plant abundance and cover determination. Faecal pellets from Eastern Grey Kangaroos and Black Wallabies were collected from ten vegetation communities during three different plant productivity periods. The spatial and temporal distribution of the animals was identified by analysing the frequency of occurrence of faecal pellets in the various communities. The use of faecal pellet density as a measure of habitat utilisation was examined. Eastern Grey Kangaroos utilised communities which were characterised by the presence of a dense grassy statum. Black Wallabies were able to utilise all of the communities of the study site regardless of their floristic composition. A reference herbarium of the leaf epidermis of 233 possible forage plant species was accumulated. These epidermal specimens were prepared for Confocal Scanning Laser Microscopy. The information gained was enhanced and stored digitally. Diagnostic information critical for the identification of plant epidermal fragments was assembled into a computer database. This was used to assist in the recognition of unknown epidermal fragments in macropodid faeces. These epidermal plant recognition techniques enabled a list of the contents of Eastern Grey Kangaroo and Black Wallaby faeces during the sampling periods in the individual communities, to be accumulated. Eastern Grey Kangaroos utilised forage which consisted largely of grass and their diets were similar regardless of their feeding sites or the time of the year. Black Wallaby diets were heterogenous with wide variations over space and time observed. The implications of these findings for current wildlife management practices were considered. Black Wallaby and Eastern Grey Kangaroo herbivory have significant impacts on ecosystem integrity. Management strategies should seek to establish ecologically sustainable populations of both species in remnant woodlands where conservation values are important.

Transformational leadership and job involvement in the Middle East: the moderating role of individually held cultural values

This study examines whether individually held cultural values moderate the relationship between transformational leadership behavior of supervisors and the job involvement of subordinates in the Middle Eastern organizational context. Hierarchical regression analysis was used to analyze survey data from 229 employees of 10 organizations in the United Arab Emirates. In line with the findings of studies in Western countries, transformational leadership was found to influence job involvement positively. In addition, the cultural value orientations of individuals were found to moderate this relationship. Collectivism positively influenced the relationship between transformational leadership and job involvement, whereas uncertainty avoidance had a negative effect. These findings provide an insight into how transformational leadership may be used to motivate culturally diverse groups of employees within the Middle East. To enhance job involvement, organizations need to realize that the attitudinal response of subordinates to transformational leadership can depend on their cultural values. This has significant implications regarding the training and effective deployment of transformational leaders within Middle Eastern organizations.

The role of ethnicity and culture in body image and disordered eating among males

An increasing number of researchers have examined body image concerns, disordered eating, and other behaviors associated with increasing muscle size among men from different cultural groups. However, to date there has been no synthesis or evaluation of these studies. In this paper we specifically review studies which have included a comparison between males from different cultural groups with White males on body image concerns or other related behaviors. The groups include Blacks, Hispanic Americans, Asians, Native Americans, Pacific Islanders, and men from Middle Eastern countries. Overall, evidence suggests that males from a range of cultural groups engage in more extreme body change strategies and binge eating than Whites. On the other hand, there is no consistent pattern which summarizes the nature of body image concerns across the different cultures. Mediating and/or moderating variables are proposed to account for the inconsistent findings. These include body build, levels of acculturation, socio-economic status, media exposure, and internalization of the muscular and lean body ideal.

Culture and trade

This investigation emphasises the significant role socio-cultural considerations play in Australia's education sector initiatives in the Middle East, and the direct impact this has on wider Australian-Middle Eastern trade and strategic relations. In order to enhance these relations, there is an urgent need for Australia to develop a more sophisticated policy of engagement that moves away from historical and contemporary misconceptions.

What is so ‘primitive’ about ‘primitive democracy’? Comparing the ancient Middle East and classical Athens

This chapter seeks to delve deeper into the ancient history of democracy than is normally permitted, back to a time preceding the developments of classical Athens, when the earliest signs of organized society and complex governmental systems emerged across the ancient Middle East. It then seeks to compare and contrast these ancient Middle Eastern examples with those of classical Athens and to offer new insights into, and questions about, the nature and history of democracy. Building on some recent work (Fleming, 2004; Isakhan, 2007a; Keane, 2009: 78–155), this chapter also hopes to move the discussion beyond the phrase usually associated with ancient Middle Eastern democracies, that of ‘primitive democracy’. This chapter also argues that, while the Middle Eastern experiments were less rigid and formalized, they were in no measurable sense more ‘primitive’ than the later example offered by classical Athens. However, this essay also cautiously notes that, while not all of the elements which made ancient Athens significant occurred in the same way and at the same time in the ancient Middle East, all of them did exist at varying times and in varying guises across these earlier civilizations. To demonstrate this thesis, the remainder of the chapter utilizes several of the key criteria by which we commonly measure Athenian democracy – the functioning of its assembly, the mechanisms of justice and of the law, the varying voting and elective procedures, the rights and freedoms of the citizens, and the systematic exclusion of ‘non-citizens’ – and discusses precedents and parallels drawn from the extant evidence concerning the ancient Middle East.
