Interpreting electrochemical noise resistance as a statistical linear polarisation resistance

A theoretical analysis on the electrochemical noise resistance is carried out based on basic electrochemical corrosion theory. It is proven that the noise resistance is equivalent to the polarisation resistance and is in fact a special form of linear polarisation resistance, namely statistical linear polarisation resistance.

Charting Australia Felix : re-interpreting cultural landscape creation through a land health lens

The landscape of the Western District of Victoria has been extensively transformed in the imagery and aspirations of United Kingdom estates but markedly modified to address the climatic and agricultural prospects of the District landscape. By assembling land, the original squatters had a clean sheet to map, comprehend, and configure an economically viable pastoral estate. ‘Charting Australia Felix’ seeks to ascertain the spatial and geographical logic and rationale that informed this pastoral estate formation. These settlers mastered an economically viable estate that respected climate, soil quality and ensured water security which were the essential ingredients of a quality land holding; their successful grazing and specialisation were dependent upon these attributes. Thus, they successfully comprehended the essences of the landscape in line with contemporary land care and rural land management strategies. Charting Australia Felix involves the use of the historic landscape characterisation method to map, assess and model some 5 exemplar pastoral stations in the Western District to quantify their temporal landscape characteristics, their responses to landscape evolution, and change to test and quantify what the archetypes are that may have informed these patterns. Using Murndal and Glenormiston pastoral stations as the lens of investigation, a preliminary appraisal is offered in this paper.

Using immersive and interactive approaches to interpreting traumatic experiences for tourists: potentials and limitations

This chapter uses three cases studies - the Melbourne Watch House Experience, the Titanic international travelling exhibition and the interpretation centre underneath the Memorial for the Murdered Jews of Europe in Berlin to discuss the ethics and politics involved in using strategies of interpretation that foster identification with victims.

Cross-curriculum priorities and the ethics of interpreting Indigenous texts

Deakin University’s first-year unit, ‘Reading Children’s Texts’, is mandatory for the B.Ed. (Primary). Newly revised, it addresses the cross- curriculum priorities, Indigenous histories and cultures, and Australia’s engagements with Asia. The unit introduces the study of narrative, genre, and ideology. But how should the political topics embedded in the English curriculum be framed for pre-service teachers, and how relevant are literary texts to the teaching of ethical interpretation of texts to both primary and secondary students?

A new framework for interpreting the outcomes of imperfectly blinded controlled clinical trials

It is well known that the outcome of an intervention is affected both by the inherent effects of the intervention and the patient's expectations. For this reason in comparative clinical trials an effort is made to conceal the nature of the administered intervention from the participants in the trial i.e. to blind the trial. Yet, in practice perfect blinding is impossible to ensure or even verify post hoc. The current clinical standard is to follow up the trial with an auxiliary questionnaire, which allows trial participants to express in closed form their belief concerning the intervention, i.e. trial group assignment (treatment or control). Auxiliary questionnaire responses are then used to compute the extent of blinding in the trial in the form of a blinding index. If the estimated extent of blinding exceeds a particular threshold the trial is deemed sufficiently blinded; otherwise, the strength of evidence of the trial is brought into question. This may necessitate that the trial is repeated. In this paper we make several contributions. Firstly, we identify a series of problems of the aforesaid clinical practice and discuss them in context of the most commonly used blinding indexes. Secondly, we formulate a novel approach for handling imperfectly blinded trials. We adopt a feedback questionnaire of the same form as that which is currently in use, but interpret the collected data using a novel statistical method, significantly different from that proposed in the previous work. Unlike the previously proposed approaches, our method is void of any ad hoc free parameters and robust to small changes in the participants' feedback responses. Our method also does not discard any data and is not predicated on any strong assumptions used to interpret participants' feedback. The key idea behind the present method is that it is meaningful to compare only the corresponding treatment and control participant sub-groups, that is, sub-groups matched by their auxiliary responses. A series of experiments on simulated trials is used to demonstrate the effectiveness of the proposed approach and its superiority over those currently in use.

Encountering the ‘other’: interpreting student experiences of a multi-sensory museum exhibition

The Immigration Museum Melbourne, Australia, launched the Identity: Yours, Mine, Ours exhibition in 2011. Aimed primarily at secondary school students, this long-term installation seeks to foster reflection on identity and belonging, as well as dialogue about racism, through an interactive, immersive museum experience. This paper describes a multi-method research project, which included narrative interviews, focus groups and video diaries with 47 Year 11–12 students from three secondary schools in Victoria, Australia, and discusses each method's contribution to an overall empirical understanding of the installation's impact on students' experiences. Emerging findings suggest the ways in which the exhibition space supports students to encounter and engage with individual stories and experiences, thus moving beyond an abstract tolerance of cultural diversity by unsettling the self and destabilising stereotyped and prejudiced interpretations of the ‘other’. The paper concludes by discussing the potential for triangulated qualitative approaches to provide rich emic perspectives on multi-sensory exhibitions.

Interpreting behaviors from accelerometry: a method combining simplicity and objectivity.

Quantifying the behavior of motile, free-ranging animals is difficult. The accelerometry technique offers a method for recording behaviors but interpretation of the data is not straightforward. To date, analysis of such data has either involved subjective, study-specific assignments of behavior to acceleration data or the use of complex analyses based on machine learning. Here, we present a method for automatically classifying acceleration data to represent discrete, coarse-scale behaviors. The method centers on examining the shape of histograms of basic metrics readily derived from acceleration data to objectively determine threshold values by which to separate behaviors. Through application of this method to data collected on two distinct species with greatly differing behavioral repertoires, kittiwakes, and humans, the accuracy of this approach is demonstrated to be very high, comparable to that reported for other automated approaches already published. The method presented offers an alternative to existing methods as it uses biologically grounded arguments to distinguish behaviors, it is objective in determining values by which to separate these behaviors, and it is simple to implement, thus making it potentially widely applicable. The R script coding the method is provided.
