Perceptual Or Analytical Processing? Evidence From Children's And Adult's Performance On The Euclidean Traveling Salesperson Problem, Iris Van Rooij, Alissa Schactman, Helena Kadlec, Ulrike Stege Dec 2006

Perceptual Or Analytical Processing? Evidence From Children's And Adult's Performance On The Euclidean Traveling Salesperson Problem, Iris Van Rooij, Alissa Schactman, Helena Kadlec, Ulrike Stege

The Journal of Problem Solving

The Euclidean Traveling Salesperson Problem (E-TSP) is a useful task to study how humans optimize when faced with computational intractability. It has been found that humans are capable of finding high-quality solutions for E TSP in a relatively short time and with seemingly little cognitive effort. This observation has led to two general proposals: The high quality of performance on E-TSP reflects (a) the output of automatic and innate perceptual processes or (b) a fundamentally intelligent approach to the task by humans. An experiment was performed to compare performance of three age groups (7- year-olds, 12-year-olds, and adults). Our findings …

A Comparison Of Heuristic And Human Performance On Open Versions Of The Traveling Salesperson Problem, James N. Macgregor, Edward P. Chronicle, Thomas C. Ormerod Dec 2006

A Comparison Of Heuristic And Human Performance On Open Versions Of The Traveling Salesperson Problem, James N. Macgregor, Edward P. Chronicle, Thomas C. Ormerod

The Journal of Problem Solving

We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally intractable and, as with the standard TSP, people appear to be able to find good solutions with relative ease. The three heuristics used mechanisms that have been cited as potentially relevant in human performance in the standard task. These were: convex hull, nearest neighbor, and …

Human Performance On Visually Presented Traveling Salesperson Problems With Varying Numbers Of Nodes, Matthew Dry, Michael D. Lee, Douglas Vickers, Peter Hughes Dec 2006

Human Performance On Visually Presented Traveling Salesperson Problems With Varying Numbers Of Nodes, Matthew Dry, Michael D. Lee, Douglas Vickers, Peter Hughes

The Journal of Problem Solving

We investigated the properties of the distribution of human solution times for Traveling Salesperson Problems (TSPs) with increasing numbers of nodes. New experimental data are presented that measure solution times for carefully chosen representative problems with 10, 20, . . . 120 nodes. We compared the solution times predicted by the convex hull procedure proposed by MacGregor and Ormerod (1996), the hierarchical approach of Graham, Joshi, and Pizlo (2000), and by five algorithms drawn from the artificial intelligence and operations research literature. The most likely polynomial model for describing the relationship between mean solution time and the size of a …

Are Individual Differences In Performance On Perceptual And Cognitive Optimization Problems Determined By General Intelligence?, Nicholas R. Burns, Michael D. Lee, Douglas Vickers Dec 2006

Are Individual Differences In Performance On Perceptual And Cognitive Optimization Problems Determined By General Intelligence?, Nicholas R. Burns, Michael D. Lee, Douglas Vickers

The Journal of Problem Solving

Studies of human problem solving have traditionally used deterministic tasks that require the execution of a systematic series of steps to reach a rational and optimal solution. Most real-world problems, however, are characterized by uncertainty, the need to consider an enormous number of variables and possible courses of action at each stage in solving the problem, and the need to optimize the solution subject to multiple interacting constraints. There are reliable individual differences in people’s abilities to solve such realistic problems. It also seems likely that people’s ability to solve these difficult problems reflects, or depends on, their intelligence. We …

Visual Learning Objects: Enable Faculty To Focus On Active Learning, Pandeli Glavanis Dr. Dec 2006

Visual Learning Objects: Enable Faculty To Focus On Active Learning, Pandeli Glavanis Dr.

Faculty Journal Articles

In two recent issues of New Chalk Talk (Vol.6, Issue 2 & 6) I suggested that “learning objects” enhance active learning and that “visual learning objects”, in particular, contribute significantly to the learning relationship. In this issue I wish to elaborate on how such “visual learning objects” are the key element that liberates faculty from having to design and construct their own demonstrations and illustrations (reinvent the wheel) in their respective courses and thus enable them to focus on critical and active learning instead.

Information Security Management And Virtual Collaboration: A Western Australian Perspective, Rosanna Fanciulli Dec 2006

Information Security Management And Virtual Collaboration: A Western Australian Perspective, Rosanna Fanciulli

Australian Information Security Management Conference

This paper presents an ongoing case study into stakeholder perceptions regarding information security management systems in emergent organisations operating in Western Australia. It takes a socio-political perspective on the problem of how to manage simultaneously virtual collaboration and information security management. A literature review introduces the context and history of the research. In light of this, it is proposed that social and political issues need to be researched and addressed before many of the existing technological strategies for information security will succeed. The research project is then outlined and the design and preliminary results presented. The results point to a …

The Information Security Ownership Question In Iso/Iec 27001 – An Implementation, Lizzie Coles-Kemp, Richard E. Overill Dec 2006

The Information Security Ownership Question In Iso/Iec 27001 – An Implementation, Lizzie Coles-Kemp, Richard E. Overill

Australian Information Security Management Conference

The information security management standard ISO/IEC 27001 is built on the notion that information security is driven by risk assessment and risk treatment. Fundamental to the success of risk assessment and treatment is the decision making process that takes risk assessment output and assigns decisions to this output in terms of risk treatment actions. It is argued that the effectiveness of the management system lies in its ability to make effective, easytoimplement and measurable decisions. One of the key issues in decision making is ownership. In this paper two aspects of information security ownership are considered: ownership of the asset …

Individuals’ Perceptions Of Wireless Security In The Home Environment, Patryk Szewczyk Dec 2006

Individuals’ Perceptions Of Wireless Security In The Home Environment, Patryk Szewczyk

Australian Information Security Management Conference

Research in 802.11 wireless networking has in the past focused predominantly on corporate wireless network use, or identifying the flaws in wireless security. This study was aimed to determine the individuals’ perceptions of wireless security in the home environment. 163 volunteers completed a survey on their perceptions, knowledge, experiences and attitudes towards wireless networking. The results of the survey indicated that there is little difference in knowledge between those who had worked in the IT industry, and those who did not. The sources of information used to configure wireless networks are not improving the knowledge respondents had on wireless security. …

Making Research Real: Is Action Research A Suitable Methodology For Medical Information Security Investigations?, Patricia A. Williams Dec 2006

Making Research Real: Is Action Research A Suitable Methodology For Medical Information Security Investigations?, Patricia A. Williams

Australian Information Security Management Conference

In the medical field, information security is an important yet vastly underrated issue. Research into the protection of sensitive medical data is often technically focused and does not address information systems and behavioural aspects integral to effective information security implementation. Current information security policy and guidelines are strategically oriented which, whilst relevant to large organisations, are less supportive to smaller enterprises such as primary care practices. Further, the conservative nature of the medical profession has been shown to hinder investigation into information technology use and management, making effective improvement based on research problematical. It is an environment which relies greatly …

Unsupervised Neural Pattern Classifiers For Oral Vowel Pronunciation Of Foreign-Accented Speech, Joseph Hecker Dec 2006

Unsupervised Neural Pattern Classifiers For Oral Vowel Pronunciation Of Foreign-Accented Speech, Joseph Hecker

All Theses

This thesis describes the development of unsupervised neural-based pattern classifiers for the training of vowel pronunciations for students learning a foreign language. This paper examines American learners of the French language. A corpus of single word utterances is compiled from a group of native French speakers. Cepstral features are used to train two unsupervised neural pattern classifiers: a self-organizing map and a growing neural gas. The development and justification for the use of these classifiers is presented. The output from the classifier is translated to a bar graph for visual assessment. The degree to which the utterance sounds native is …

Mapping The Consensual Knowledge Of Security Risk Management Experts, David J. Brooks Dec 2006

Mapping The Consensual Knowledge Of Security Risk Management Experts, David J. Brooks

Australian Information Warfare and Security Conference

The security industry comprises of diverse and multidisciplined practitioners, originating from many disciplines. It has been suggested that the industry has an undefined knowledge structure, although security experts contain a rich knowledge structure. There has also been limited research mapping security expert knowledge structure, reducing the ability of tertiary educators to provide industry focused teaching and learning. The study utilized multidimensional scaling (MDS) and expert interviews to map the consensual knowledge structure of security experts in their understanding of security risk. Security risk concepts were extracted and critiqued from West Australian university courses. Linguistic analysis categorised the more utilized security …
