Three dimensional stability charts for slopes based on limit analysis methods

This paper uses finite element upper and lower bound limit analysis to produce chart solutions for three-dimensional (3D) natural slopes for both short- and long-term stability. The presented chart solutions are convenient tools that can be used for preliminary design purposes. The rigorous limit analysis results in this paper were found to bracket the true factor of safety within ±10% or better, which can be used as a benchmark for the solutions from other methods. The depth of the slip surfaces is observed to be generally shallow for most analyzed cases, particularly for the long-term slope stability problem. In addition, it was found that using a two-dimensional (2D) analysis may lead to significant differences in estimating safety factors, which can differ by 2%–60% depending on the slope geometry and soil properties. Therefore, great care and judgement are required when applying 2D analyses to 3D slope problems.

Entrapping Christian and Muslim Arabs in racial cartoons in Australia : the other anti-semitism

Racial Cartoons are a powerful force disguised as entertainment operating to shape public opinion. During the 1980s, 1990s and after 9/11 in 2001, cartoons in the Australian press were particularly directed against Muslim and Christian Arabs without remorse or fear of redress or accountability. The offensive of such cartoons has essentially been directed on three fronts—oil, politics and religion. The drawback resulting from socio-cultural, historical and other differences are no doubt visible; but equally obvious is that anti-Semitism, which was directed against the Jews in the 1930s and 1940s, is today mostly directed against the public relations deprived, opinion silenced and undemocratically governed, ethnically diverse Arabs. It is argued in this paper that several forces were behind such distorted visual strategies adopted by the Australian press. Pre-judgement stemming from an inbuilt bias of the cartoonist, or highlighting characteristics which conform to the national interest are likely factors. The debate in Australia as to whether public images and attitudes of a minority “cause” or “determine” policy or whether policy itself changes attitudes is still resting with the jury.

‘No one will ever know...’ : the Holocaust, ‘privileged’ Jews, and the ‘grey zone’

This paper explores the problems of judgement and representation in relation to Jewish victims of the Holocaust who occupied so-called privileged positions in the camps and ghettos. Such figures, forced to act in ways that have proven controversial both during and after the war, faced unprecedented ethical dilemmas under Nazi persecution. Taking Auschwitz survivor Primo Levi’s highly influential essay on the ‘grey zone’ as a point of departure, I examine the extreme situations confronted by prisoner doctors, an important – though little discussed – category of ‘privileged’ Jews. Investigating the synergies between history, memory and film, I focus particularly on the case of Gisella Perl, a prisoner doctor whose experiences in Auschwitz-Birkenau are represented in her memoir and a recent fiction film. The emotionally and morally fraught circumstances of prisoner doctors can never be fully understood, yet reflecting on the double binds they faced, and acknowledging the inherent problems involved in representing and judging them, enables a nuanced approach to the moral complexities of the Holocaust.

The strange and the familiar : seeing beyond when we know

My novel is a collection of interrelated stories. Each story is framed by the idiosyncrasies and prejudices of a different first-person voice. There are gaps in narrative time and there is disparity between the narrators’ voices. The result is a ‘discontinuous narrative’; this term describes the early work of Frank Moorhouse: ‘an innovative narrative method using interconnected stories’ (Griffith University 2011).
As I draft and re-draft the stories, I am forced to assess the interaction between the voices. I am aware of the disjuncture, and I ask myself: Why not tell the story through the eyes of one narrator? Why not choose a third-person perspective, an omniscient narrator who might collect all of the voices together, in a coherent way?
As I second-guess my approach, I realise that the splintering of voices feels like the right way to tell the story and, in this way, I approach the question of methodology. I am aware that a sense of disjuncture arises out of the medley of voices, but I also realise that the disjuncture is carefully constructed; it is not accidental. This is an intuitive judgement.
If I edit my novel ethically, I ask what the discontinuity achieves, rather than how it fails in the context of logic. This means that I recognise that the narrative begins from a place that does not worry about logic, and I realise that second-guessing the surface content of the narrative, from a rational perspective, may be counterproductive.
The conscious mind, fettered as it is with inhibitions, may fail to see that the logical track is not necessarily the most productive route. The conscious mind may not recognise that going off-track is the way forward and, perhaps, the only way that the story can become something other than what I, in my rational mind, believe that it should be.
Ethical editing means that I am attentive to my intuitive response to the narrative; it means that I tolerate incongruous elements of the narrative, even if they do not fit the criteria of logic.
Ethical editing is a meeting of minds (both mine); the fully conscious mind meets the work of the subconscious mind with surprise and approval, at best, skepticism and derision, at worst. The work of the subconscious mind is elusive but it need not be subjugated to logical, rational considerations, for this means that I delimit the work of the subconscious; it means I assess the discontinuity on the basis of an external operating system; it means that I impose certain criteria upon the surface narrative, criteria that has nothing to do with understanding why the discontinuity exists in the first instance.
Alternatively, when I pay heed to a primal moment of narrative composition, a moment that is not necessarily consciously determined or logical, I apprise the surface of the narrative as a metaphorical map, I attempt to engage with the possibilities for meaning that the map encompasses; this constitutes a quest for the unstable how of meaning attribution.

Bowerbirds, art and aesthetics : are bowerbirds artists and do they have an aesthetic sense?

Male bowerbirds create and decorate a structure called a bower which serves only to attract females for mating, and females visit and choose one among many bower owners before deciding which male to mate with. Is what they do art, and do they have an aesthetic sense? I propose operational definitions of art, judgement, and an aesthetic sense which depend upon communication theory which allow one to get explicit answers to this question. By these definitions Great Bowerbirds are artists, judge art, and therefore have an aesthetic sense.

An empirical analysis of colour image segmentation using fuzzy c-means clustering

In this paper, an empirical analysis to examine the effects of image segmentation with different colour models using the fuzzy c-means (FCM) clustering algorithm is conducted. A qualitative evaluation method based on human perceptual judgement is used. Two sets of complex images, i.e., outdoor scenes and satellite imagery, are used for demonstration. These images are employed to examine the characteristics of image segmentation using FCM with eight different colour models. The results obtained from the experimental study are compared and analysed. It is found that the CIELAB colour model yields the best outcomes in colour image segmentation with FCM.

A hybrid Kansei engineering system using the self-organizing map neural network

Kansei Engineering (KE), a technology founded in Japan initially for product design, translates human feelings into design parameters. Although various intelligent approaches to objectively model human functions and therelationships with the product design decisions have been introduced in KE systems, many or the approaches are not able to incorporate human subjective feelings and preferenees into the decision-making process. This paper proposes a new hybrid KE system that attempts to make the machine-based decision-making process closely resembles the real-world practice. The proposed approach assimilates human perceptive and associative abililities into the decision-making process of the computer. A number of techniques based on the Self-Organizing Map (SOM) neural network are employed in the backward KE system to reveal the underlying data structures that are involved in the decision-making process. A case study on interior design is presented to evaluate the efficacy of the proposed approach. The results obtained demonstrate tbe effectiveness of the proposed approach in developing an intelligent KE system which is able to combine huiiUUI feelings and preferences into its decision making process.

Evaluation of delivery of the switched on secondary science professional learning (SOSSPL) program

The Switched On Secondary Science Professional Learning (SOSSPL) program consisted of three days professional learning. Days 1 and 2 were undertaken consecutively, with Day 3 following a break of several weeks. The break allowed sufficient time for teachers to undertake a small classroom-based project within one of the topics teachers will be teaching at the time. The program was designed to build teacher capacity to improve learning outcomes in secondary science.

Evaluation of delivery of the switched on secondary science professional learning (SOSSPL) program (2011-12)

The Switched On Secondary Science Professional Learning (SOSSPL) program consisted of three days professional learning for Victorian DEECD secondary science teachers. Days 1 and 2 were undertaken consecutively, with Day 3 following a break of several weeks. The break allowed sufficient time for teachers to undertake a small classroom-based project within one of the topics they were teaching at the time. The program was designed to build teacher capacity to improve student learning outcomes in secondary science.

The program supported teachers to plan and implement classroom sequences that focused on student construction and interpretation of different representations of the science concepts and processes that are described by the Victorian Essential Learning Standards (VELS): Science and the Science Continuum P-10. The Deakin University team in collaboration with the Department of Education and Early Childhood Development (DEECD) produced curriculum resources for the program that encapsulated a representational focus to the teaching and learning of science. The program explored and linked to core DEECD resources such as the e5 Instructional Model and the Science Continuum P-10.
The SOSSPL program was delivered in all Victorian DEECD regions in 2010-11 and was evaluated (Hubber et al, 2011). The program was delivered again in all Victorian DEECD regions in 2011-12. The evaluation of the 2011-12 program is reported here with some comparisons made to the findings from the previously delivered program.
This evaluation of the SOSSPL program involved an online survey, daily workshop evaluations, focus group and presentations data of the participating teachers’ classroom-based projects. The aim of the evaluation was to make a judgement about the effectiveness of the SOSSPL program in terms of building teacher capacity to improve student learning outcomes in secondary science.

Bourdieu and educational research: thinking tools, relational thinking, beyond epistemological innocence

The main aim of this chapter is to provide an introduction to the theoretical work of Pierre Bourdieu, and to outline different ways in which Bourdieu’s work is influential and has been engaged with in education research and to suggest implicitly the usefulness of this work for educational researchers. In order to do this, we draw on a range of Bourdieu’s own writing published singly or with colleagues, emphasising in particular his engagements with education. Part of our treatment also deals with his wider writing that has subsequently been influential for education researchers, and in particular Bourdieu’s anthropological writing and account of practice (Bourdieu 1977, 1990), his approach to social class and cultural issues, his account of the judgement of taste and distinctions (Bourdieu, 1984), and his later politically focused writing (Bourdieu, 1989/1996, 2003, 2004c, 2005a).

Checked baggage: spatial negotiations in contemporary air travel

This paper examines the act of undertaking international air travel and analyses how it forces individuals to consider a range of ideas as a result of dislocation and attempts to re-align themselves within spatial, material and biological structures. In order to balance the shifts between spatial and material experiences, travellers employ imaginative and perceptive procedures, gaining knowledge through experience. At the intersection of participatory and spatial boundaries through the lens of multi-disciplinary literature, this paper explores how practices of individuals within international air travel provides alternative modes of thinking and navigating through personal, cultural and globalised public spaces.

Multipoint haptic mediator interface for robotic teleoperation

Despite recent advances in artificial intelligence and autonomous robotics, teleoperation can provide distinct benefits in applications requiring real-time human judgement and intuition. However, as robotic systems are increasingly becoming sophisticated and are performing more complex tasks, realizing these benefits requires new approaches to teleoperation. This paper introduces a novel haptic mediator interface for teleoperating mobile robotic platforms that have a variety of manipulators and functions. Identical master-slave bilateral teleoperation of the robotic manipulators is achieved by representing them in virtual reality and by allowing the operator to interact with them using a multipoint haptic device. The operator is also able to command motions to the mobile platform by using a novel haptic interaction metaphor rather than a separate dedicated input device. The presented interaction techniques enable the operator to perform a wide range of control functions and achieve functionality similar to that of conventional teleoperation schemes that use a single haptic interface. The mediator interface is presented, and important considerations such as workspace mapping and scaling are discussed. © 2015 IEEE.

Engaging clinicians in research: Issues to consider

The beginning of nursing research is attributed to Florence Nightingale whose research during the Crimean War in the 1850s ultimately shaped health care, including nursing practice. Modern research, like clinical care, is influenced by technological, societal, organisational and environmental changes. However, ‘nursing research’ is a simple term that may not encompass complex inter-related concepts and practices and various research methods: quantitative, qualitative, implementation science, evaluation and audit. All research methods follow a similar basic ‘research process,’ but the way the process is applied and rigor is demonstrated differs among the methods. All nurses must engage in research on some level, given they practice in a climate of evidence-based care and are expected to adhere to evidence-based protocols and guidelines. In addition, they need to be able to implement evidence-based best practice and use clinical judgement to treat each person as an individual.
