Supporting process model validation through natural language generation

The design and development of process-aware information systems is often supported by specifying requirements as business process models. Although this approach is generally accepted as an effective strategy, it remains a fundamental challenge to adequately validate these models given the diverging skill set of domain experts and system analysts. As domain experts often do not feel confident in judging the correctness and completeness of process models that system analysts create, the validation often has to regress to a discourse using natural language. In order to support such a discourse appropriately, so-called verbalization techniques have been defined for different types of conceptual models. However, there is currently no sophisticated technique available that is capable of generating natural-looking text from process models. In this paper, we address this research gap and propose a technique for generating natural language texts from business process models. A comparison with manually created process descriptions demonstrates that the generated texts are superior in terms of completeness, structure, and linguistic complexity. An evaluation with users further demonstrates that the texts are very understandable and effectively allow the reader to infer the process model semantics. Hence, the generated texts represent a useful input for process model validation.

Robust and reversible numerical set watermarking

Numeric sets can be used to store and distribute important information such as currency exchange rates and stock forecasts. It is useful to watermark such data for proving ownership in case of illegal distribution by someone. This paper analyzes the numerical set watermarking model presented by Sion et. al in “On watermarking numeric sets”, identifies it’s weaknesses, and proposes a novel scheme that overcomes these problems. One of the weaknesses of Sion’s watermarking scheme is the requirement to have a normally-distributed set, which is not true for many numeric sets such as forecast figures. Experiments indicate that the scheme is also susceptible to subset addition and secondary watermarking attacks. The watermarking model we propose can be used for numeric sets with arbitrary distribution. Theoretical analysis and experimental results show that the scheme is strongly resilient against sorting, subset selection, subset addition, distortion, and secondary watermarking attacks.

Factors contributing to crashes among young drivers

Young drivers are the group of drivers most likely to crash. There are a number of factors that contribute to the high crash risk experienced by these drivers. While some of these factors are intrinsic to the young driver, such as their age, gender or driving skill, others relate to social factors and when and how often they drive. This article reviews the factors that affect the risk of young drivers crashing to enable a fuller understanding of why this risk is so high in order to assist in developing effective countermeasures.

Education for Australia’s information future

Digital disruption and an increasingly networked society drive rapid change in many professions and a corresponding need for change in tertiary education. Across the world, information education has, to date, prepared graduates for employment in discrete professions, such as librarianship, records management, archives, and teacher librarianship. However, contemporary information practices are less defined and are demanding of new professional skill-sets and understandings. This paper reports a study that consulted Australia’s tertiary academics about the current circumstances of information education in the academy and elicited a vision and a concern for future directions in Australian information education.

A comparison of factors influencing perceived risk by French and Australian cyclists and drivers

Differences in the levels of risk perceived by cyclists and car drivers may contribute to the dangers in their interactions. Levels of perceived risk have been shown to vary according to personal and environmental factors and between countries. Cycling rates in France are higher than in Australia, particularly among women. This study investigated whether cultural differences between France and Australia are reflected in perceived risks for experienced adult cyclists and drivers in the two countries. In online surveys, regular cyclists (France 336, Australia 444) and drivers (France 92, Australia 151) were asked to rate the level of risk in six situations: failure to yield; going through a red light; not signalling when turning; swerving; tail-gating; and not checking traffic. The effects of type of interacting vehicle and participant type on perceived risk were similar in France and Australia. However, the influence of responsibility for the risky behaviour differed according to participant type, type of situation and nationality. When the bicycle rider committed the road rule violation, Australian cyclists and drivers gave higher risk ratings than French cyclists and drivers. In both countries, cyclists rated themselves significantly higher than drivers on the perceived control and overconfidence subscales of the perceived skill measure. The French cyclists rated themselves higher than Australian cyclists on these scales, which could be responsible for overall lower perceived risk levels when interacting with a bike. Australian cyclists rated themselves significantly lower than drivers on the incompetence subscale but French cyclists rated themselves higher than drivers. In both countries incompetence scores were positively related to levels of perceived risk. Weekly time was associated with perceived risk in Australia but not in France. Frequency of traffic violations was not associated with perceived risk in either country. In conclusion, levels of perceived risk differed between drivers and cyclists in both countries and were influenced by type of interacting vehicle, experience and perceived skill. However, some differences between the results from the two countries merit further investigation to shed light on potential improvements in safety and cycling participation.

Augmenting and assisting model elicitation tasks with 3D virtual world context metadata

Accurate process model elicitation continues to be a time consuming task, requiring skill on the part of the interviewer to extract explicit and tacit process information from the interviewee. Many errors occur in this elicitation stage that would be avoided by better activity recall, more consistent specification methods and greater engagement in the elicitation process by interviewees. Theories of situated cognition indicate that interactive 3D representations of real work environments engage and prime the cognitive state of the viewer. In this paper, our major contribution is to augment a previous process elicitation methodology with virtual world context metadata, drawn from a 3D simulation of the workplace. We present a conceptual and formal approach for representing this contextual metadata, integrated into a process similarity measure that provides hints for the business analyst to use in later modelling steps. Finally, we conclude with examples from two use cases to illustrate the potential abilities of this approach.

The New Lawyer

This text is designed to implement the Threshold Learning Outcomes (TLOs) for law in the first year, and to incorporate Sally Kift’s First Year Curriculum principles: http://tls.vu.edu.au/portal/site/trans/Resources/KiftTransitonPedagogySixPrinciples_16Nov09.pdf This is a learning-centered text book intentionally designed for first year students and written by experts in legal education and the first year experience. It is written in a tone and style that engages and communicates effectively with first year law students, without compromising its rigour. It provides students with opportunities to contextualise and make sense of their learning by connecting that learning with what they already know, and with current contemporary issues and affairs. This work is designed to ease students through the transition from a diverse variety of backgrounds (such as high school, work or other disciplines) to the first year of law. It provides practical guidance about adjusting to law school and to university. Students are asked to regularly reflect upon why they are studying law. The book also prepares law students for success in their latter year studies in law by ensuring that they are equipped with the necessary threshold concepts and foundational skills to do well: for example, research skills (particularly, online research skills), reasoning skills, written communication skills, negotiation skills, and self-management skills. A range of practical tips on studying law are provided throughout the book. The work also asks students to engage with developing an emergent sense of professional identity – including what it means to ‘think like a lawyer’. In supporting the students to engage with the concept of professional identity, the work begins a process of preparing students for transition from law school to legal practice. This is achieved by providing explanations of how the material being presented relates to the practice of law, as well as practical information relating to employability skills as a new graduate. This work has a number of learning and teaching objectives to enhance the quality of student learning in their first year of law by engaging, motivating and supporting that learning. First, the work is designed to engage first year students with their legal education and with a future sense of professional identity. It does this through its: • Dynamic writing style • Engaging format • Inclusion of contemporary issues and events • Flowcharts, checklists, mind-maps, tables and timelines • Inclusion of real-world problems and dilemmas. Second, the text motivates student learning by promoting active learning. It does this by: • Demonstrating, and asking students to practice, what they need to do – that is, the work is not simply focussed on telling students what they need to know • Including regular self-directed learning exercises throughout each chapter, such as practical exercises for the development of important foundational legal skills • Including exercises that promote student collaboration, and that require students to apply their learning to practical situations, and • Incorporating a range of interesting active thinking points and research activities. Third, the book supports student learning by encouraging reflective learning and independent learning. It does this by including: • Specific content on how to be a reflective practitioner and an independent learner • Exercises that require students to engage in independent learning, particularly in relation to legal research skill development • Exercises requiring students to reflect upon what they have learned, and encouraging students to keep a reflective learning journal • Exercises requiring students to reflect upon their own views and beliefs • Reflection on whether students have achieved the learning objectives articulated at the beginning of the chapter. The work also: • Demonstrates respect for student experiences, views, opinions and values • Acknowledges student diversity • Recognises the importance of being globally minded law students and lawyers • Supports law teachers in using the work in their classrooms through the provision of comprehensive teaching materials.

A Statutory interpretation EXperience : putting the SEX into statutory interpretation

With the growing proliferation of statute laws, the skill of statutory interpretation is an increasingly important aspect of legal practice. Despite the importance, statutory interpretation can be a challenging area of law to teach to undergraduate law students, who may find the topic dry and disengaging when taught through traditional methods. Such disengagement may adversely affect knowledge retention, particularly if the material is taught in the first or second year of study and not explicitly reinforced in subsequent years. Concern over the present standard of statutory interpretation skills being exhibited by practitioners, has prompted the Chief Justice of the Supreme Court of Queensland to contact law schools, enquiring how and to what extent statutory interpretation is being taught...

Performance psychology applied to dance

The recent interest in the area of performance psychology has included a focus on applied practice within the performing arts. The use of psychology within this field has been occurring for many years, although practice has been observed to originate primarily from within clinical psychology in dealing with ‘problems’ (e.g. eating disorders). During the past 15 years, increased interest and focus has come from the field of sport psychology and its application to fields such as dance. Experience with the application of sport psychology in the dance profession has shown that dancers identify primarily with the concept of performance psychology. The focus of applied performance psychology practice with dancers has been observed to incorporate principles from across sport, clinical and organisational psychology, yet packaged together in such a way that the focus is on performance enhancement – whether that be in terms of dance technique, artistry, creativity, or personal skill development both on and off the stage. This paper focuses upon sharing the practitioner’s experience of the delivery of performance psychology to dancers (both professionals and dancers-in-training), and discussion of the considerations related to this undertaking within this unique population.

The dynamics of expertise acquisition in sport : the role of affective learning design

Objectives The aim of this position paper is to discuss the role of affect in designing learning experiences to enhance expertise acquisition in sport. The design of learning environments and athlete development programmes are predicated on the successful sampling and simulation of competitive performance conditions during practice. This premise is captured by the concept of representative learning design, founded on an ecological dynamics approach to developing skill in sport, and based on the individual-environment relationship. In this paper we discuss how the effective development of expertise in sport could be enhanced by the consideration of affective constraints in the representative design of learning experiences. Conclusions Based on previous theoretical modelling and practical examples we delineate two key principles of Affective Learning Design: (i) the design of emotion-laden learning experiences that effectively simulate the constraints of performance environments in sport; (ii) recognising individualised emotional and coordination tendencies that are associated with different periods of learning. Considering the role of affect in learning environments has clear implications for how sport psychologists, athletes and coaches might collaborate to enhance the acquisition of expertise in sport.

Digital Modeling, Integrated Project Delivery and Industry Transformation: An Australian Case Study

This research is focused on realizing productivity benefits for the delivery of transport infrastructure in the Australian construction industry through the use of building information modeling (BIM), virtual design and construction (VDC) and integrated project delivery (IPD). Specific objectives include: (I) building an understanding of the institutional environment, business systems and support mechanisms (e.g., training and skilling) which impact on the uptake of BIM/VDC; (II) gathering data to undertake a cross-country analysis of these environments; and (III) providing strategic and practical outcomes to guide the uptake of such processes in Australia. Activities which will inform this research include a review of academic literature and industry documentation, semi-formal interviews in Australia and Sweden, and a cross-country comparative analysis to determine factors affecting uptake and associated productivity improvements. These activities will seek to highlight the gaps between current-practice and best-practice which are impacting on widespread adoption of BIM/VDC and IPD. Early findings will be discussed with intended outcomes of this research being used to: inform a national public procurement strategy; provide guidelines for new contractual frameworks; and contribute to closing skill gaps. Keywords: building information modeling (BIM); virtual design and construction (VDC); integrated project delivery (IPD); transport infrastructure; Australia; procurement

Blended delivery and online assessment : scaffolding student reflections in work-integrated learning

This paper documents a teaching innovation addressing the challenges of embedding and assessing reflective practice in work-integrated learning, specifically marketing internships. We identify four issues relating to this problem: lack of knowledge or skill for reflection, limitations of physical journals, facilitation of different forms of reflection, and suitable models for teaching and assessing reflection. The paper outlines a blended approach combining face-to-face workshops and online resources, and using online reflective journals and digital stories as assessment. The approach and assessment tasks can be implemented in a variety of marketing and business units.

Construction of volcanic records from marine sediment cores : a review and case study (Montserrat, West Indies)

Detailed knowledge of the past history of an active volcano is crucial for the prediction of the timing, frequency and style of future eruptions, and for the identification of potentially at-risk areas. Subaerial volcanic stratigraphies are often incomplete, due to a lack of exposure, or burial and erosion from subsequent eruptions. However, many volcanic eruptions produce widely-dispersed explosive products that are frequently deposited as tephra layers in the sea. Cores of marine sediment therefore have the potential to provide more complete volcanic stratigraphies, at least for explosive eruptions. Nevertheless, problems such as bioturbation and dispersal by currents affect the preservation and subsequent detection of marine tephra deposits. Consequently, cryptotephras, in which tephra grains are not sufficiently concentrated to form layers that are visible to the naked eye, may be the only record of many explosive eruptions. Additionally, thin, reworked deposits of volcanic clasts transported by floods and landslides, or during pyroclastic density currents may be incorrectly interpreted as tephra fallout layers, leading to the construction of inaccurate records of volcanism. This work uses samples from the volcanic island of Montserrat as a case study to test different techniques for generating volcanic eruption records from marine sediment cores, with a particular relevance to cores sampled in relatively proximal settings (i.e. tens of kilometres from the volcanic source) where volcaniclastic material may form a pervasive component of the sedimentary sequence. Visible volcaniclastic deposits identified by sedimentological logging were used to test the effectiveness of potential alternative volcaniclastic-deposit detection techniques, including point counting of grain types (component analysis), glass or mineral chemistry, colour spectrophotometry, grain size measurements, XRF core scanning, magnetic susceptibility and X-radiography. This study demonstrates that a set of time-efficient, non-destructive and high-spatial-resolution analyses (e.g. XRF core-scanning and magnetic susceptibility) can be used effectively to detect potential cryptotephra horizons in marine sediment cores. Once these horizons have been sampled, microscope image analysis of volcaniclastic grains can be used successfully to discriminate between tephra fallout deposits and other volcaniclastic deposits, by using specific criteria related to clast morphology and sorting. Standard practice should be employed when analysing marine sediment cores to accurately identify both visible tephra and cryptotephra deposits, and to distinguish fallout deposits from other volcaniclastic deposits.

Recognising emotional expressions of complaining customers : A cross-cultural study

Purpose This study aims to test service providers’ ability to recognise non-verbal emotions in complaining customers of same and different cultures. Design/methodology/approach In a laboratory study, using a between-subjects experimental design (n = 153), we tested the accuracy of service providers’ perceptions of the emotional expressions of anger, fear, shame and happiness of customers from varying cultural backgrounds. After viewing video vignettes of customers complaining (with the audio removed), participants (in the role of service providers) assessed the emotional state of the customers portrayed in the video. Findings Service providers in culturally mismatched dyads were prone to misreading anger, happiness and shame expressed by dissatisfied customers. Happiness was misread in the displayed emotions of both dyads. Anger was recognisable in the Anglo customers but not Confucian Asian, while Anglo service providers misread both shame and happiness in Confucian Asian customers. Research limitations/implications The study was conducted in the laboratory and was based solely on participant’s perceptions of actors’ non-verbal facial expressions in a single encounter. Practical implications Given the level of ethnic differences in developed nations, a culturally sensitive workplace is needed to foster effective functioning of service employee teams. Ability to understand cultural display rules and to recognise and interpret emotions is an important skill for people working in direct contact with customers. Originality/value This research addresses the lack of empirical evidence for the recognition of customer emotions by service providers and the impact of cross-cultural differences.

Evaluation of the Australian Performing Arts Market 2014-2018 - Year One Report

The Australia Council awarded the tender of APAMs 2014, 2016 and 2018 to the Brisbane Powerhouse. The Australia Council, in awarding the contract for the presentation of APAM by Brisbane Powerhouse, stipulated that a formal evaluation of the three iterations of APAM and activity in the intervening years be undertaken. Queensland University of Technology, Creative Industries Faculty, under the leadership of Associate Professor Sandra Gattenhof, were contracted to undertake the formal evaluation. This is the first year report on the Brisbane iteration of the Market. This report has drawn from data collected across a range of sources, drawing on the scoping study undertaken by Justin Macdonnell addressing the Market from 1994–2010; the tender document submitted by the Brisbane Powerhouse; in-person interviews with APAM staff, APAM Stakeholders, Vox Pops from delegates in response to individual sessions, producer company/artist case studies and, most significantly, responses from a detailed online survey sent to all delegates. The main body of the report is organised around three key research aims, as outlined in the Brisbane Powerhouse Tender document (2011). These have been articulated as: Evaluation of international market development outcomes through showcasing work to targeted international presenters and agents Evaluation of national market development outcomes through showcasing work to national presenters and producers Evaluation of the exchange ideas, dialogue, skill 
development, partnerships, collaborations and co- productions and networks with local and international peers. The culmination of the data analysis has been articulated through five key recommendations, which may assist the APAM delivery team for the next version, in 2016. In summary, the recommendations are described as: 1. Indigenous focus to remain central to the conception and delivery of APAM 2. Re-framing APAM’s function and its delivery 3. Logistics and communications in a multi-venue approach, including communications and housekeeping, volunteers, catering, re-calibrating the employment of Brisbane Powerhouse protocols and processes for APAM 4. Presentation and promotion for presenters 5. Strategic targeting of Asian producers.
