Design tools for event-driven software systems

Proposes a design method for the development of software in Visual BASIC whose programming environment is multi-paradigm. Extensions to structure charts and pseudocode to incorporate the three paradigms have been developed based on the premise that procedural models, event-driven forms and objects are mutually exclusive in operation.

Reducing obesity in early childhood : results from romp & chomp, an Australian community-wide intervention program

Background: There is growing evidence that community-based interventions can reduce childhood obesity in older children.
Objective: We aimed to determine the effectiveness of the Romp & Chomp intervention in reducing obesity and promoting healthy eating and active play in children aged 0–5 y.
Design: Romp & Chomp was a community-wide, multisetting, multistrategy intervention conducted in Australia from 2004 to 2008. The intervention occurred in a large regional city (Geelong) with a target group of 12,000 children and focused on community capacity building and environmental (political, sociocultural, and physical) changes to increase healthy eating and active play in early-childhood care and educational settings. The evaluation was repeat cross-sectional with a quasiexperimental design and comparison sample. Main outcome measures were body mass index (BMI), standardized BMI (zBMI; according to the Centers for Disease Control and Prevention 2000 reference charts), and prevalence of overweight/obesity and obesity-related behaviors in children aged 2 and 3.5 y.
Results: After the intervention there was a significantly lower mean weight, BMI, and zBMI in the 3.5-y-old subsample and a significantly lower prevalence of overweight/obesity in both the 2- and 3.5-y-old subsamples (by 2.5 and 3.4 percentage points, respectively) than in the comparison sample (a difference of 0.7 percentage points; P < 0.05) compared with baseline values. Intervention child-behavioral data showed a significantly lower intake of packaged snacks (by 0.23 serving), fruit juice (0.52 serving), and cordial (0.43 serving) than that in the comparison sample (all P < 0.05).
Conclusion: A community-wide multisetting, multistrategy intervention in early-childhood settings can reduce childhood obesity and improve young children's diets. This trial was registered with the Australian Clinical Trials Registry at anzctr.org.au as ACTRN12607000374460.

Aboriginal women and reconciliation in Australia : communication strategies and symbolism

This thesis explores the voices of Aboriginal women in the Reconciliation movement from 1991to 2001. It charts their success and failure, the power of the media and Reconciliation symbolism. Some of these women leaders retain a passionate commitment to Reconciliation while others have totally withdrawn from the process.

The longitudinal influence of home and neighbourhood environments on children's body mass index and physical activity over 5 years : the CLAN study

Objective: To determine the independent contributions of family and neighbourhood environments to changes in youth physical activity and body mass index (BMI) z-score over 5 years.

Methods: In 2001, 2004 and 2006, 301 children (10–12 years at baseline) had their height and weight measured (BMI was converted to z-scores using Centers for Disease Control and Prevention reference charts; see http://www.cdc.gov/growthcharts) and moderate-to-vigorous physical activity (MVPA) assessed using accelerometers. In 2001, parents reported on the home environment (social support, role modelling, rules and restrictions, physical environment) and perceived neighbourhood environment (local traffic, road safety, sporting venues, public transport), and Geographic Information Systems were used to map features of the neighbourhood environment (destinations, road connectivity, traffic exposure). Generalized estimating equations were used to predict average BMI z-score and MVPA over time from baseline home and perceived and objective neighbourhood environment factors.

Results: Among boys, maternal education and heavy traffic were inversely associated, and sibling physical activity, maternal role modelling of MVPA and the presence of dead-end roads were positively associated with MVPA. Having unmarried parents, maternal MVPA role modelling and number of home sedentary items were positively associated with BMI z-score among boys. Among girls, having siblings, paternal MVPA role modelling, physical activity rules and parental physical activity co-participation were positively associated with MVPA. Having unmarried parents and maternal sedentary behaviour role modelling were positively associated, and number of sedentary behaviour rules and physical activity items were inversely associated with BMI z-score among girls.

Conclusion: The home environment seems more important than the neighbourhood environment in influencing children's physical activity and BMI z-score over 5 years. Physical activity and weight gain programmes among youth should focus on parental role modelling, rules around sedentary and active pursuits, and parental support for physical activity. Intervention studies to investigate these strategies are warranted.

The client's complex decision-making environment on international mega projects

More than ever before, architectural, engineering and construction (AEC) firms are working on international mega projects. The mega project environment offers a range of opportunities for firms but is but is characterised by a high level of risk and uncertainty. International mega projects bring together networks of people with differing backgrounds and cultures to work in unfamiliar locations to integrate the social, economic, technical and political components of design and construction. Within such an intense environment there is a process of rapid relationship development at an unprecedented level. The interests and power relations on such projects are often very strong given the vast amount of money, jobs, environmental impacts, publicity and national prestige involved. Therefore in a field as costly or consequential as mega project design and construction there is an increased need to effectively manage these projects given the associated high risks of failure. Internationalisation is a relatively new field of research in the AEC sector and past research has tended to focus on explaining the attitudes and behaviour of the industry itself towards improving performance on such projects. To date there has been little research investigating the sophistication of the international client in terms of their regular business environment which is characterised by a set of social, economic and political responsibilities. The values that clients ascribe to their everyday practices and experiences inevitably condition how they act economically, which in turn impacts upon project decision-making. Clients establish the structural organisation of project teams through the procurement strategy and establish the context for effective decision-making. To a large extent they establish a unique culture that project team members need to work within and make decisions. Since clients establish the context within which firms operate the findings of past studies on the industry’s position and attitudes are more indicative than enlightening. Clients occupy a distinctly different position in the construction supply chain and therefore experience and respond to project matters based upon their environment and not the construction industry environment. Clients are confronted with uncertainties and need support to help them understand the critical role that they play in creating good decision-making environments. This theoretical paper seeks to develop a rationale for studying the client’s complex decision-making environment on international mega projects. Specifically it charts the quest for improved industry performance through client leadership as documented in various industry and government publications since the 1940s and highlights that there has been considerable attention to address industry problems through client leadership, however, with little evidence that the issues have been resolved. This paper is positioned within a PhD study, which seeks to move beyond the aspirations of policymakers and idealistic descriptions of how clients ought to behave to explain the reality of what really happens on mega project client decision-making based upon a critique of cultural political economy.

Using the psychrometric chart in building measurements

This paper centres around the presentation of multiple measured results on a psychrometric chart. The psychrometric chart was programmed in Microsoft Office Excel to accommodate measured results. It was written because existing programs appear not to cater for the researcher wishing to enter results electronically onto the chart. Furthermore, many existing charts are complex and cluttered displaying up to ten attributes, being intended for engineering design, whereas presenting the behaviour of living and working environments is focused on wet and dry bulb temperature and relative humidity. As well as results, users would also like to specify and adjust the ‘comfort zone’ (a shaded area on the chart) for different ‘adaptive’ or ‘seasonal’ conditions. The comfort zone is bounded by lines of constant heat loss from the skin, relative humidity and wet-bulb temperature. The paper presents various applications of the psychrometric chart for the analysis and reporting of research and discusses the programming of Microsoft Office Excel to generate the chart and display user data.

The roles, responsibilities and development needs of quality managers in Britain and Australia

This paper compares and contrasts the career experiences and development needs of 334 British quality managers compared with Australian quality managers based on two Australian surveys. The quality managers in both countries brought wide functional experience to their roles, with many coming in particular from production and operations and general management. In their current roles major sources of job satisfaction for managers in both countries were improving efficiency and problem solving, whereas aspects of employee relations was a source of least satisfaction. Both groups of quality managers utilised a very limited range of quality tools, the most popular being brainstorming, control charts and Pareto analysis, with virtually no mention of more sophisticated tools like Six sigma, which is in stark contrast to American managers. Also British and Australian managers showed little awareness in terms of their development needs for a broader background in quality, which could disadvantage their companies in global markets.

Website physical activity interventions : preferences of potential users

Information and communication technologies (particularly websites and e-mail) have the potential to deliver health behavior change programs to large numbers of adults at low cost. Controlled trials using these new media to promote physical activity have produced mixed results. User-centered development methods can assist in understanding the preferences of potential participants for website functions and content, and may lead to more effective programs. Eight focus group discussions were conducted with 40 adults after they had accessed a previously trialed physical activity website. The discussions were audio taped, transcribed and interpreted using a themed analysis method. Four key themes emerged: structure, interactivity, environmental context and content. Preferences were expressed for websites that include simple interactive features, together with information on local community activity opportunities. Particular suggestions included online community notice boards, personalized progress charts, e-mail access to expert advice and access to information on specific local physical activity facilities and services. Website physical activity interventions could usefully include personally relevant interactive and environmentally focused features and services identified through a user-centered development process.

Application of computational media aesthetics methodology to extracting color semantics in film

Using film grammar as the underpinning, we study the extraction of structures in video based on color using a wide configuration of clustering methods combined with existing and new similarity measures. We study the visualisation of these structures, which we call Scene-Cluster Temporal Charts and show how it can bring out the interweaving of different themes and settings in a film. We also extract color events that filmmakers use to draw/force a viewer's attention to a shot/scene. This is done by first extracting a set of colors used rarely in film, and then building a probabilistic model for color event detection. We demonstrate with experimental results from ten movies that our algorithms are effective in the extraction of both scene-cluster temporal charts and color events.

Heritage of war

The Heritage of War is an interdisciplinary study of the ways in which heritage is mobilized in remembering war, and in reconstructing landscapes, political systems and identities after conflict. It examines the deeply contested nature of war heritage in a series of places and contexts, highlighting the modes by which governments, communities, and individuals claim validity for their own experiences of war, and the meanings they attach to them.

From colonizing violence in South America to the United States’ Civil War, the Second World War on three continents, genocide in Rwanda and continuing divisions in Europe and the Middle East, these studies bring us closer to the very processes of heritage production. The Heritage of War uncovers the histories of heritage: it charts the constant social and political construction of heritage sites over time, by a series of different agents, and explores the continuous reworking of meaning into the present.

What are the forces of contingency, agency and political power that produce, define and sustain the heritage of war? How do particular versions of the past and particular identities gain legitimacy, while others are marginalised? In this book contributors explore the active work by which heritage is produced and reproduced in a series of case studies of memorialization, battlefield preservation, tourism development, private remembering and urban reconstruction. These are the acts of making sense of war; they are acts that continue long after violent conflict itself has ended.

An evaluation of a national program to implement the cornell scale for depression in dementia into routine practice in aged care facilities

Background: Screening tools have been recommended for use in aged care to improve the detection and treatment of depression. This study aimed to evaluate the impact of a program for the routine implementation of the Cornell Scale for Depression in Dementia in Australian facilities, to determine whether use of the instrument by nurses led to further monitoring of depressive symptoms, medical referral, and changes in treatments prescribed for depression.
Methods: A file review was completed for 412 participants out of a total of 867 older people (47.5%) who resided in ten aged care facilities. The review examined Cornell Scale assessment data, medication charts, medical history, nursing progress notes, and resident care plans. Nursing staff who administered the Cornell Scale to each participant were also interviewed, and ten facilitymanagers took part in an interview to determine barriers to the effective implementation of the instrument.
Results: The Cornell Scale had been administered to 46.8% of the sample in the previous 12 months, with 25% of these participants scoring 9–13 and 27% scoring 14 and above. Less than one third of the residents with high scores were monitored by the staff following the assessment. Only 18% of residents with high scores were referred for further assessment of depression, while 10% received a treatment change.
Conclusions: The absence of a protocol for responding to high Cornell Scale scores limited the potential of this program to result in widespread improved treatment of depressed older people. The use of the Cornell Scale by aged care nurses with limited training raised concern.

Identification of concurrent control chart patterns with singular spectrum analysis and learning vector quantization

Identification of unnatural control chart patterns (CCPs) from manufacturing process measurements is a critical task in quality control as these patterns indicate that the manufacturing process is out-of-control. Recently, there have been numerous efforts in developing pattern recognition and classification methods based on artificial neural network to automatically recognize unnatural patterns. Most of them assume that a single type of unnatural pattern exists in process data. Due to this restrictive assumption, severe performance degradations are observed in these methods when unnatural concurrent CCPs present in process data. To address this problem, this paper proposes a novel approach based on singular spectrum analysis (SSA) and learning vector quantization network to identify concurrent CCPs. The main advantage of the proposed method is that it can be applied to the identification of concurrent CCPs in univariate manufacturing processes. Moreover, there are no permutation and scaling ambiguities in the CCPs recovered by the SSA. These desirable features make the proposed algorithm an attractive alternative for the identification of concurrent CCPs. Computer simulations and a real application for aluminium smelting processes confirm the superior performance of proposed algorithm for sets of typical concurrent CCPs.

Real estate graduates’ employability skills : the perspective of human resource managers of surveying firms

Purpose – The purpose of this paper is to report further on research funded by the Centre for Education in the Built Environment (CEBE) into real estate programmes of study in UK universities (Poon and Hoxley). The aim of this paper is to identify human resource managers’ view on the employability skills of real estate graduates. It also compares the views on the employability skills of real estate graduates between human resource managers, a large sample of real estate employers and real estate course directors.

Design/methodology/approach – This paper presents the research findings of eight interviews with human resource managers who work in different types of surveying firms. The approach for collecting their view of the employability skills required by real estate graduates was through gathering their opinions on three charts. These charts compare what employers feel graduates require and what they feel graduates demonstrate in 31 knowledge areas, 20 skills and 21 attributes, alongside a list of additional competencies made by graduates and employers which was developed as part of an earlier study.

Findings – The human resource managers identified the key employability skills for real estate graduates as soft skills, in particular report writing skills, communication skills, presentation skills, client care and professional standards. The human resource managers of real estate consultancy firms also voiced their concern regarding graduates’ lack of commercial awareness, which echoed the same view from real estate employers and real estate course directors mentioned in the previous research (Poon, Hoxley and Fuchs). Therefore, it is necessary for universities to embed these soft skills, such as commercial awareness in the curriculum in order to enhance the employability of graduates.

Originality/value – This paper makes an original contribution to existing literature on the identification and discussion of employability skills for real estate graduates. It describes pioneering research focusing on the human resource managers’ perspective of the real estate graduate employability skills.

Impact of personalized recommendation and social comparison on learning behaviours and outcomes

ELearning suffers from the lack of face-to-face interaction and can deprive learners from the benefits of social interaction and comparison. In this paper we present the results of a study conducted for the impact of social comparison. The study was conducted by collecting students’ engagement with an eLearning tool, the attendance, and grades scored by students at specific milestones and presented these metrics to students as feedback using Kiviat charts. The charts were complemented with appropriate recommendations to allow them to adapt their study strategy and behaviour. The study spanned over 4 semesters (2 with and 2 without the Kiviats) and the results were analysed using paired T tests to test the pre and post results on topics covered by the eLearning tool. Survey questionnaires were also administered at the end for qualitative analysis. The results indicated that the Kiviat feedback with recommendation had positive impact on learning outcomes and attitudes.

Can't sleep

A devised, alternative musical set in the future, the play charts the story of a group of scientists, who have been tasked with capturing light in deep space. The play’s premise is bound to a strong ideological question: Life After Death or Light After Death? While religions believe in, but cannot prove, ‘life after death’, science proves that there is ‘light after death’… Lotu then asks, what if light holds consciousness? And what if scientific technique could be developed to capture light and experiment on it? “Can’t Sleep” is a story that will trick you into believing that you have embarked on a journey into the absurd, only to reach the destination of a collective reality. Lotu Theatre was awarded a $15,000 Arts Project Grant from Regional Arts Victoria to create the play and to explore the process of professional artists development through the collaborative process.
