A review of the Ustilago-Sporisorium-Macalpinomyces complex

The fungal genera Ustilago, Sporisorium and Macalpinomyces represent an unresolved complex. Taxa within the complex often possess characters that occur in more than one genus, creating uncertainty for species placement. Previous studies have indicated that the genera cannot be separated by morphology alone. Here we chronologically review the history of the Ustilago-Sporisorium-Macalpinomyces complex, argue for its resolution and suggest methods to accomplish a stable taxonomy. A combined molecular and morphological approach is required to identify synapomorphic characters that underpin a new classification. Ustilago, Sporisorium and Macalpinomyces require explicit re-description and new genera, based on monophyletic groups, are needed to accommodate taxa that no longer fit the emended descriptions. A resolved classification will end the taxonomic confusion that surrounds generic placement of these smut fungi.

Soral synapomorphies are significant for the systematics of the Ustilago-Sporisorium-Macalpinomyces complex (Ustilaginaceae)

The genera Ustilago, Sporisorium and Macalpinomyces are a polyphyletic complex of plant pathogenic fungi. The four main morphological characters used to define these genera have been considered homoplasious and not useful for resolving the complex. This study re-evaluates character homology and discusses the use of these characters for defining monophyletic groups recovered from a reconstructed phylogeny using four nuclear loci. Generic delimitation of smut fungi based on their hosts is also discussed as a means for identifying genera within this group. Morphological characters and host specificity can be used to circumscribe genera within the Ustilago-Sporisorium-Macalpinomyces complex.

Analysis of productive performance of crop production systems: an integrated analytical framework

Recent literature has argued that environmental efficiency (EE), which is built on the materials balance (MB) principle, is more suitable than other EE measures in situations where the law of mass conversation regulates production processes. In addition, the MB-based EE method is particularly useful in analysing possible trade-offs between cost and environmental performance. Identifying determinants of MB-based EE can provide useful information to decision makers but there are very few empirical investigations into this issue. This article proposes the use of data envelopment analysis and stochastic frontier analysis techniques to analyse variation in MB-based EE. Specifically, the article develops a stochastic nutrient frontier and nutrient inefficiency model to analyse determinants of MB-based EE. The empirical study applies both techniques to investigate MB-based EE of 96 rice farms in South Korea. The size of land, fertiliser consumption intensity, cost allocative efficiency, and the share of owned land out of total land are found to be correlated with MB-based EE. The results confirm the presence of a trade-off between MB-based EE and cost allocative efficiency and this finding, favouring policy interventions to help farms simultaneously achieve cost efficiency and MP-based EE.

The Spartan-3E tutorial 3 : using the LCD display [version 1.0]

This tutorial is designed to assist users who wish to use the LCD screen on the Spartan-3E board. In this tutorial, the PicoBlaze microcontroller is used to control the LCD. The tutorial is organised into three Parts. In Part A, code is written to display the message "Hello World" on the LCD. Part B demonstrates how to define and display custom characters. Finally, Part C shows how the display can be shifted and flashed. Shifting is done by using a delay in the main PicoBlaze program loop, while flashing is done using the PicoBlaze interrupt. The slider switches can be used to select the shifting direction, and to turn shifting and flashing on and off.

Preliminary study on the stability of highly sensitive fiber Bragg grating temperature sensors [对高灵敏光纤光栅温度传感器的稳定性的初探]

As a novel sensitive element and due to its advantages of immunity to electrical interference, distributed measurement, etc., fiber Bragg grating (FBG) has been researched widely. To realize the substitution of high accurate electronic temperature sensors, high sensitive FBG temperature sensors can be made by taking advantage of its characters of being sensitive to both temperature and strain. Although there are reports about high sensitive FBG temperature sensors, however, few about their stability have been done. We manufactured a high sensitive FBG temperature sensor, and put it together with an average FBG temperature sensor and an electronic crystal temperature sensor into a stainless steel container filled by water to observe the room temperature change. By comparing their results in two weeks, we have found out that: although the high sensitive FBG temperature sensor is in much better agreement with the electronic crystal sensor than the average FBG sensor is, it has occurred some small drifts. Because the drifts appeared in the process of further pulling the FBG, it might be a result of the slip of the FBG fixing points. This contributes some good experiences to the application of FBG in high accuracy temperature measurement.

Integrating crowd-behavior modeling into military simulation using game technology

Crowds of noncombatants play a large and increasingly recognized role in modern military operations and often create substantial difficulties for the combatant forces involved. However, realistic models of crowds are essentially absent from current military simulations. To address this problem, the authors are developing a crowd simulation capable of generating crowds of noncombatant civilians that exhibit a variety of realistic individual and group behaviors at differing levels of fidelity. The crowd simulation is interoperable with existing military simulations using a standard, distributed simulation architecture. Commercial game technology is used in the crowd simulation to model both urban terrain and the physical behaviors of the human characters that make up the crowd. The objective of this article is to present the design and development process of a simulation that integrates commercially available game technology with current military simulations to generate realistic and believable crowd behavior.

The implications of cross-regional differences for the design of In-vehicle Information Systems : a comparison of Australian and Chinese drivers

The increasing global distribution of automobiles necessitates that the design of In-vehicle Information Systems (IVIS) is appropriate for the regions to which they are being exported. Differences between regions such as culture, environment and traffic context can influence the needs, usability and acceptance of IVIS. This paper describes two studies aimed at identifying regional differences in IVIS design needs and preferences across drivers from Australia and China to determine the impact of any differences on IVIS design. Using a questionnaire and interaction clinics, the influence of cultural values and driving patterns on drivers' preferences for, and comprehension of, surface- and interaction-level aspects of IVIS interfaces was explored. Similarities and differences were found between the two regional groups in terms of preferences for IVIS input control types and labels and in the comprehension of IVIS functions. Specifically, Chinese drivers preferred symbols and Chinese characters over English words and were less successful (compared to Australians) at comprehending English abbreviations, particularly for complex IVIS functions. Implications in terms of the current trend to introduce Western-styled interfaces into other regions with little or no adaptation are discussed.

A distance too far away : a novel and exegesis

This practice-led research examines the generative function of loss in fiction that explores themes of grief and longing. This research considers how loss may be understood as a structuring mechanism through which characters evaluate time, resolve loss and affect future change. The creative work is a work of literary fiction titled A Distance Too Far Away. Aubrey, the story’s protagonist, is a woman in her twenties living in Brisbane in the early 1980s, carving out an independent life for herself away from her family. Through a flashback narrative sequence, told from the perspective of the twelve year narrator, Aubrey retraces a significant point of rupture in her life following a series of family tragedies. A Distance Too Far Away explores the tension between belonging and freedom, and considers how the past provides a malleable space for illuminating desire in order to traverse the gap between the world as it is and the world as we want it to be. The exegetical component of this research considers an alternative critical frame for interpreting the work of American author Anne Tyler, a writer who has had a significant influence on my own practice. Frequently criticised for creating sentimental and inert characters, many critics observe that nothing happens in Tyler’s circular plots. This research challenges these assertions, and through a contextual analysis of Tyler’s Ladder of Years (1995) investigates how Tyler engages with memory and nostalgia in order to move across time and resolve loss.

Variation in leaf structure of the invasive Madeira vine (Anredera cordifolia, Basellaceae) at different light levels

Madeira vine (Anredera cordifolia (Ten.) Steenis) is a climber in the angiosperm family Basellaceae. It is native to South America and has naturalised in Australia. It is regarded as a serious environmental weed because of the structural damage it causes to native vegetation. The present study, for the first time, documents anatomical and morphological traits of the leaves of A. cordifolia and considers their implications for its ecology and physiology. Plants were grown under three different light levels, and anatomical and morphological leaf characters were compared among light levels, among cohorts, and with documented traits of the related species, Basella alba L. Stomata were present on both the adaxial and abaxial sides of the leaf, with significantly more stomata on the abaxial side and under high light. This may account for the ability of this species to fix large amounts of carbon and rapidly respond to light gaps. The leaves had very narrow veins and no sclerenchyma, suggesting a low construction cost that is associated with invasive plants. There was no significant difference in any of the traits among different cohorts, which agrees with the claim that A. cordifolia primarily propagates vegetatively. The anatomy and morphology of A. cordifolia was similar to that of B. alba.

Review : "Everynight...Everynight" -- Alkinos Tsilimidos

Synopsis and review of the Australian prison film Everynight...Everynight (Alkinos Tsilimidos, 1994). Includes cast and credits. An opening title states that Everynight… Everynight is a true story, but due to “legal implications”, the characters have been fictionalised. Another title dedicates the film to the memory of Christopher Dale Flannery, an infamous underworld figure known as ‘Mr Rent-a-Kill’ who spent time in H Division in the 1970s and 1980s. Originally from Melbourne, Flannery was a major figure in the Sydney ‘gang wars’ of 1984-85, dramatised in the television series Underbelly: A Tale of Two Cities (2009). He disappeared in mid-1985; there are several conflicting stories about his fate. The character of Bryant appears to have been based on Stan Taylor who had spent time in H Division with Flannery. Taylor was sentenced to life imprisonment without parole in 1988 for the 1986 bombing of police headquarters in Melbourne...

Review : "Ghosts...of the Civil Dead" -- John Hillcoat

Synopsis and review of the Australian prison film Ghosts...of the Civil Dead (John Hillcoat, 1988). Drawing heavily from the book In the Belly of the Beast by American author and long-term prisoner Jack Henry Abbott, as well as from the historical and philosophical work of Michel Foucault (the credits include ‘Foucault Authority – Simon During’), Ghosts… Of the Civil Dead is a searing critique of the so-called ‘new generation’ prison system developed in the United States and recently introduced in Australia. Director John Hillcoat and producer Evan English conducted extensive research for the film, including spending time at the National Institute of Corrections, a think tank in Colorado, and visiting numerous institutions like the ‘new Alcatraz’ at Marion Illinois and other maximum security prisons across the United States. Using a mix of professionals and non-actors, including former prisoners and prison guards, the ‘story’ was workshopped during a lengthy rehearsal period with many actual events and experiences of participants incorporated into the film. The end result deliberately blurs the line between American and Australian prison experience to make the political point that what had happened in the US – from where many events and characters, and much of the architecture and design of the prison are drawn – was beginning to happen in Australia. The film emphasises the vicious cycle of institutionalisation, and highlights the role state authorities play in manufacturing, provoking and manipulating violence and fear both in prisons and in wider society as a means to augment policing and surveillance of the population, to oppress the working classes, and to maintain the political status quo...

Review : "Not Quite Hollywood" -- Mark Hartley

Synopsis and review of the Australian documentary Not Quite Hollywood (Mark Hartley, 2008). Not Quite Hollywood might just as accurately have been titled Not Quite Australian Cinema. The film begins from the premise that the vast range of films it covers have been unduly overlooked by critics, historians and scholars of the Australian cinema despite often enormous box office success. Much of the blame for the marginalisation of these films is placed at the feet of former Sydney Film Festival director and long-time film critic for The Australian newspaper David Stratton, well-known to Australian audiences as one half of the ‘David and Margaret’ couple who have dominated film reviewing on Australian television for many years. Stratton’s books on the Australian film revival The Last New Wave (1980) and The Avocado Plantation (1990) are said to have set the tone for later writers by reviling or simply ignoring many of the films produced in Australia in the 1970s and 1980s in favour of a canon of films and directors deemed more culturally and artistically worthy. Perhaps predictably, Not Quite Hollywood swings the other way. The back-slapping, anecdotal, revisionist history told through the many interviews with key figures from the time is only occasionally interrupted by Bob Ellis and Phillip Adams, who are only slightly uncomfortably cast as defenders of the mainstream views. The interviews and clips from the films are interspersed with the fan-boy enthusiasms of Quentin Tarantino whose geek-chic profile and encyclopaedic knowledge of exploitation and genre cinema are milked to the full. In sharp contrast, Ellis’s scorn for these filmmakers and their films is total, but it is his withering and slanderous assessments of the characters, talents and practices of producers like Antony I Ginnane and John Lamond that leavens this sometimes stodgy stew of selfcongratulation...

Metabolic urinary profiling of alcohol hepatotoxicity and intervention effects of Yin Chen Hao Tang in rats using ultra-performance liquid chromatography/electrospray ionization quadruple time-of-flight mass spectrometry

This paper was designed to study metabonomic characters of the hepatotoxicity induced by alcohol and the intervention effects of Yin Chen Hao Tang (YCHT), a classic traditional Chinese medicine formula for treatment of jaundice and liver disorders in China. Urinary samples from control, alcohol- and YCHT-treated rats were analyzed by ultra-performance liquid chromatography/electrospray ionization quadruple time-of-flight mass spectrometry (UPLC/ESI-QTOF-MS) in positive ionization mode. The total ion chromatograms obtained from the control, alcohol- and YCHT-treated rats were easily distinguishable using a multivariate statistical analysis method such as the principal components analysis (PCA). The greatest difference in metabolic profiling was observed from alcohol-treated rats compared with the control and YCHT-treated rats. The positive ions m/z 664.3126 (9.00 min) was elevated in urine of alcohol-treated rats, whereas, ions m/z 155.3547 (10.96 min) and 708.2932 (9.01 min) were at a lower concentration compared with that in urine of control rats, however, these ions did not indicate a statistical difference between control rats and YCHT-treated rats. The ion m/z 664.3126 was found to correspond to ceramide (d18:1/25:0), providing further support for an involvement of the sphingomyelin signaling pathway in alcohol hepatotoxicity and the intervention effects of YCHT.

Contemporary Australian masculinities and De Certeau’s concept of la perruqe in Christos Tsiolkas’ novel The Slap (2008)

This paper will focus on how Christos Tsiolkas the author of The Slap (2008) invites us to view the complex range of private lives of his male characters living in suburban Melbourne through their daily routines, conversations and innermost thoughts. On the surface most appear to be participating in and achieving a certain level of success in their lives. However, this novel reveals when we agitate and dig below the “practices of everyday life” there is often a disquiet simmering away under the facade of family harmony, male bravado and contentment. This paper will argue that as a result of dissatisfaction with the established order of their lives, each man has managed to create another level of meaning for himself, his own form of la perruque (De Certeau 2011: 29),the concept of living proposed by Michel De Certeau. A treatment of the characters in this article draws on, and is used to illustrate the paradigm.
