The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
THE RELATIONSHIP BETWEEN POLICE AND OTHER GOVERNMENT AGENCIES: RECENT CHANGES IN PERSPECTIVE IN QUEENSLAND
No full textThis paper examines the changing relationships between police and other government agencies, in the context of recent experience in Queensland. Three aspects of the changing relationships are examined: divesting police of extraneous duties; responsibility for all government agencies to consider the law enforcement impact of their policies; and the moves for police to work alongside and play a key role in a broad range of policy and program developmen
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Oil extraction processes in microalgae
No full textMicroalgae are an attractive source for biofuels due to their high growth rates and lipid content. However, up to the present time, the extraction of lipids from wet microalgae biomass remains an energy-intensive step, and an impediment for the economically viable large scale bio-oil production. During the extraction process, cell disruption and drying are two of the most energy-consuming steps. Several studies on genetic modification of microalgae towards lipid accumulation enhancement, or to reduce the harvesting and lipid extraction cost have been carried out successfully. This chapter aims to summarize the recent developments in microalgal oil extraction processes, including drying methods, cell disruption methods, conventional or supercritical solvent extraction methods, and recent approaches for direct biodiesel production. The current developments in metabolic engineering for lipids production are also reviewed. Hydrothermal liquefaction is also included as an alternative route to convert wet biomass into bio-crude oil.NSERC Discovery Gran
Determination of alpha-dicarbonyl compounds in foods with a high content of free sugars
No full textaplha-Dicarbonyl compounds are highly reactive substances found in foods and beverages. They are formed during processing, cooking and prolonged storage as end products of lipid peroxidation, microorganism metabolites, and caramelization or Maillard reaction products. Precise and accurate determination of their content in foods is important, because they exert both positive and negative effects on human health, even at low doses. The method most frequently applied to determine alpha-dicarbonyl compounds in foods and beverages involves their derivatization with 1,2- diaminobenzene, to obtain specific quinoxaline derivatives that can be detected by HPLC or GC. In the literature derivatization conditions vary widely, particularly the pH of the medium and temperature, without considering that alpha-dicarbonyl compounds can form as glucose and fructose fragmentation products. Our data demonstrate that derivatization conditions critically affect the fragmentation process in sugar-rich matrices. In this work we tested a range of derivatization conditions to find the combination that would allow accurate and precise determination of alpha-dicarbonyl compounds sugar-rich matrices. Formation of alpha-dicarbonyl compounds due to glucose and fructose fragmentation was found to be avoided by using an acidic medium (pH 3.0) at low temperature (25 °C) while allowing a derivatization yield close to 100% for the alpha-dicarbonyl compounds considered (methylglyoxal and diacetyl). Analysis of four types of red wine having different sugar contents (two table wines and two dessert wines) confirmed that these conditions prevent alpha-dicarbonyl compound overestimation as well as false positive results

Deep Learning in Sentiment Analysis: A Survey of Recent Architectures
No full textHumans are increasingly integrated with devices that enable the collection of vast unstructured opinionated data. Accurately analysing subjective information from this data is the task of sentiment analysis (an actively researched area in NLP). Deep learning provides a diverse selection of architectures to model sentiment analysis tasks and has surpassed other machine learning methods as the foremast approach for performing sentiment analysis tasks. Recent developments in deep learning architectures represent a shift away from Recurrent and Convolutional neural networks and the increasing adoption of Transformer language models. Utilising pre-trained Transformer language models to transfer knowledge to downstream tasks has been a breakthrough in NLP.
This survey applies a task-oriented taxonomy to recent trends in architectures with a focus on the theory, design and implementation. To the best of our knowledge, this is the only survey to cover state-of-the-art Transformer-based language models and their performance on the most widely used benchmark datasets. This survey paper provides a discussion of the open challenges in NLP and sentiment analysis. The survey covers five years from 1st Jul 2017 to 1st Jul 2022
