Student-generated submicro diagrams : a useful tool for teaching and learning chemical equations and stoichiometry

This paper reports on a pedagogical approach to the teaching of chemical equations introduced to first year university students with little previous chemical knowledge. During the instruction period students had to interpret and construct diagrams of reactions at the submicro level, and relate them to chemical equations at the symbolic level with the aim of improving their conceptual understanding of chemical equations and stoichiometry. Students received instruction in symbol conventions, practice through graded tutorial tasks, and feedback on their efforts over the semester. Analysis of the student responses to formative test and summative exam items over consecutive years indicates that there was a consistent improvement in the abilities of the various cohorts to answer stoichiometry questions correctly. The responses provide evidence for diagrams of the submicro level being used as tools for reasoning in solving chemical problems, to recognise misconceptions of chemical formulae and to recognise the value of using various multiple representations of chemical reactions connecting the submicro and symbolic levels of representation. The student-generated submicro diagrams serve as a visualisation tool for teaching and learning abstract concepts in solving stoichiometric problems. We argue that the use of diagrams of the submicro level provides a more complete picture of the reaction, rather than a net summary of a chemical equation, leading to a deeper conceptual understanding.

Representation and judgement : 'privileged' Jews in Holocaust writing and film

This thesis analyses the ways in which moral judgements of so-called privileged Jews are constructed in Holocaust representations. ‘Privileged’ Jews include those prisoners in the camps and ghettos who held positions which gave them access to material and other benefits. Subject to extreme levels of coercion, these victims were compelled to act in ways that have often been judged as both self-serving and harmful to fellow inmates. Such controversial figures constitute an intrinsically important, frequently misunderstood and hastily judged facet of the Holocaust. Scholars have neglected the problem of judgement in relation to ‘privileged’ Jews; nonetheless, Holocaust texts frequently portray these liminal figures.

Of crucial importance to the thesis is Primo Levi’s paradigmatic essay entitled ‘The Grey Zone,’ which directly engages with the complex and sensitive issue of ‘privileged’ Jews. Levi argues that due to the extreme ethical dilemmas that ‘privileged’ Jews confronted, any judgement of these victims needs to be suspended. However, if, as Levi suggests, judgement is at times impossible, the thesis challenges Levi’s assumption by contending that representations of ‘privileged’ Jews inevitably take a moral position. In this way, the thesis conceptualises judgement as a ‘limit’ of representation. Indeed, it is shown that Levi himself cannot abstain from judging those for whom he argues judgement should be suspended.

The thesis takes Levi’s concept of the ‘grey zone’ as a point of departure in order to examine the problems of judgement and representation in relation to ‘privileged’ Jews. Analysis focuses on Raul Hilberg’s influential historical work and examples of documentary and fiction films. The thesis examines how Hilberg and several filmmakers employ conventions as a means of conveying judgement. It is argued that self-reflexive representations of ‘privileged’ Jews in film, particularly fictional dramatisation, have the potential to provide a nuanced representation of ‘privileged’ Jews, which engages with Levi’s ideas by questioning the possibility of judgement.

Pervasive limitations : innovating with ambient intelligence (AmI) technologies and restricted absorptive capacity in Australian SME manufacturers

The last 25 years have seen rapid increases in the number and sophistication of technological and process innovations in large manufacturers, producing dramatic improvements in productivity and efficiency. However, smaller manufacturers’ adoption of such innovations has been uneven. Ambient Intelligence (AmI) technologies are being positioned as the next performance and productivity enhancing purchase for manufacturers. This paper defines and gives examples of AmI technologies in current use, summarises AmI technologies of potential interest to small and medium enterprise (SME) manufacturers, and identifies potential impacts of restricted absorptive capacity in SMEs on the adoption of AmI technologies. Comparing two SME manufacturers, one from Germany and one from Australia illustrates a potential application of generic AmI technology based business solutions to a range of SME manufacturers.

The interface between intrapreneurship, innovation and IT governance

The purpose of this conceptual paper is to examine the links, as reported in the international literature, between intrapreneurship, innovativeness and IT governance within medium to large organizations. A cross disciplinary literature review was conducted and yielded a theoretical framework for identifying and understanding the critical elements underpinning and driving innovation and intrapreneurship performance and their relationship with key aspects of IT governance within organizations.

Mislabeling marine protected areas and why it matters : a case study of Australia

As part of international obligations and national policies, most nations are working toward establishing comprehensive, adequate, and representative systems of terrestrial and marine protected areas (MPAs). Assigning internationally recognized International Union for Conservation of Nature (IUCN) protected area categories to these MPAs is an important part of this process. The most recent guidance from the IUCN clearly states that commercial or recreational fishing is inappropriate in MPAs designated as category II (National Park). However, in at least two developed countries with long histories of protected area development (e.g., Canada and Australia), category II is being assigned to a number of MPAs that allow some form of commercial or recreational fishing. Using Australia as a case study, this article explores the legal and policy implications of applying protected area categories to MPAs and the consequences for misapplying them. As the Australian Government is about to embark on potentially one of the largest expansions of MPA networks in the world, ensuring the application of IUCN categories is both transparent and consistent with international practice will be important, both for the sake of international conventions and to accurately track conservation progress.

Social responsibility and credit availability

There has been a widespread increase in the use of consumer credit and therefore consumer indebtedness. Some of this increase has been within that segment of the population least able to afford debt of any kind – welfare recipients. This qualitative study demonstrates some interesting attitudes to debt, as well as differences in peoples’ perceptions of acceptable debt and their debt-management strategies. This study suggests that action is required by those responsible for the marketing of credit to this vulnerable group and government policymakers to provide a socially responsible approach to manage this societal concern.

The interaction of discipline and culture in academic writing

Work in contrastive rhetoric has often sought to examine the impact of culturally-based writing conventions on text production and has outlined cultural differences in texts in different languages. At the same time. the study of specialised languages has often claimed a degree of uniformity in text construction both at the level of culture and at the level of the discipline. It appears however that approaches which consider just culture or just discipline miss part of the picture. This paper argues that considerations of discipline and culture are. complex and interrelated and that this complexity and interrelationship can be seen at several different levels in specialised academic texts.

Novel approach to determining tempo and dramatic story sections in motion pictures

This paper presents an original computational approach to extraction of movie tempo for deriving story sections and events that convey high level semantics of stories portrayed in motion pictures, thus enabling better video annotation and interpretation systems. This approach, inspired by the existing cinematic conventions known as film grammar, uses the attributes of motion and shot length to define and compute a novel continuous measure of tempo of a movie. Tempo flow plots are derived for several full-length motion pictures and edge detection is performed to extract dramatic story sections and events occurring in the movie, underlined by their unique tempo. The results confirm reliable detection of actual distinct tempo changes and serve as useful index into the dramatic development and narration of the story in motion pictures.

Media independent knowledge indexing and retrieval

Composing a multimedia presentation may require creation or generation of suitable images and video segments, as well as animation, sound, or special effects. Obtaining images or video sequences can be prohibitively expensive when costs of travel to location, equipment, staff, etc, are considered. Those problems can be alleviated with the use of pictorial and video digital libraries, such libraries require methods for comprehensive indexing and annotation of stored items and efficient retrieval tools.

We propose a system based on user oriented perceptions as they influence query formation in image and video retrieval. We present a method based on user dependent conceptual structures for creating and maintaining indexes to images and video sequences.

Role of shot length in characterizing tempo and dramatic story sections in motion pictures

Motivated by existing cinematic conventions known as film grammar, we proposed a computational approach to determine tempo as a high-level movie content descriptor as well as means for deriving dramatic story sections and events occurring in movies. Movie tempo is extracted from two easily computed aspects in our approach: shot length and motion. Story sections and events are generally associated with changes in tempo, and are thus identified by edges located in the tempo function. In this paper, we analyze our initial founding of the tempo function on the basis that the distribution of both shot length and motion in movies is normal. Given that the distribution of shot length is approximately Weibull as confirmed in our experiments, we examine the impact of modelling and modifying the contributions of shot length to tempo. We derive an appropriate normalization function that faithfully encapsulates the role of shot length in tempo perception, and analyze the changes to the story sections identified in films.

A genre analysis of reprint request emails written by EFL and physics professionals

The present study aimed to analyze reprint request e-mail messages written by postgraduates (MA students) of two fields of study, namely Physics and EFL, to realize the differences and similarities between the two email types. The results showed that the two corpora were much alike at the level of move schemata while there were some differences concerning strategies and microstructural features.
