Workflow patterns put into context

In his paper “Approaches to Modeling Business Processes. A Critical Analysis of BPMN, Workflow Patterns and YAWL”, Egon Börger criticizes the work of the Workflow Patterns Initiative in a rather provocative manner. Although the workflow patterns and YAWL are well established and frequently used, Börger seems to misunderstand the goals and contributions of the Workflow Patterns Initiative. Therefore, we put the workflow patterns and YAWL in their historic context. Moreover, we address some of the criticism of Börger by pointing out the real purpose of the workflow patterns and their relationship to formal languages (Petri nets) and real-life WFM/BPM systems.

Putting the Repository First: Implementing a Repository to RIS Workflow for QUT ePrints

As one of the first institutional repositories in Australia and the first in the world to have an institution-wide deposit mandate, QUT ePrints has great ‘brand recognition’ within the University (Queensland University of Technology) and beyond. The repository is managed by the library but, over the years, the Library’s repository team has worked closely with other departments (especially the Office of Research and IT Services) to ensure that QUT ePrints was embedded into the business processes and systems our academics use regularly. For example, the repository is the source of the publication information which displays on each academic’s Staff Profile page. The repository pulls in citation data from Scopus and Web of Science and displays the data in the publications records. Researchers can monitor their citations at a glance via the repository ‘View’ which displays all their publications. A trend in recent years has been to populate institutional repositories with publication details imported from the University’s research information system (RIS). The main advantage of the RIS to Repository workflow is that it requires little input from the academics as the publication details are often imported into the RIS from publisher databases. Sadly, this is also its main disadvantage. Generally, only the metadata is imported from the RIS and the lack of engagement by the academics results in very low proportions of records with open access full-texts. Consequently, while we could see the value of integrating the two systems, we were determined to make the repository the entry point for publication data. In 2011, the University funded a project to convert a number of paper-based processes into web-based workflows. This included a workflow to replace the paper forms academics used to complete to report new publications (which were later used by the data entry staff to input the details into the RIS). Publication details and full-text files are uploaded to the repository (by the academics or their nominees). Each night, the repository (QUT ePrints) pushes the metadata for new publications into a holding table. The data is checked by Office of Research staff the next day and then ‘imported’ into the RIS. Publication details (including the repository URLs) are pushed from the RIS to the Staff Profiles system. Previously, academics were required to supply the Office of research with photocopies of their publication (for verification/auditing purposes). The repository is now the source of verification information. Library staff verify the accuracy of the publication details and, where applicable, the peer review status of the work. The verification metadata is included in the information passed to the Office of Research. The RIS at QUT comprises two separate systems built on an Oracle database; a proprietary product (ResearchMaster) plus a locally produced system known as RAD (Research Activity Database). The repository platform is EPrints which is built on a MySQL database. This partly explains why the data is passed from one system to the other via a holding table. The new workflow went live in early April 2012. Tests of the technical integration have all been successful. At the end of the first 12 months, the impact of the new workflow on the proportion of full-texts deposited will be evaluated.

Holistic blended design studio model : potential implication in education of Iran

Iran as a developing country faces many considerable shortages of both physical learning environment and inefficient budget to resolve this shortage. Today, Iran needs a $28 billion budget to add 23,000 schools to the existing 120,000 schools to be able to omit two shifts schools [1], [2]. Moreover, the standard learning space is 6-8 square meter per student, while this rate for big cities in Iran is about one square meter per student [1]. This decrease the time students spend in schools. In addition, the education approach in k-12 and higher education is still teacher-centered based and needs to be contemporized with educational, cultural, and technological changes.

Bending and blurring blended learning boundaries [Extended Abstract]

This presentation presents a blended learning model that provides greater opportunity for learning to be self-managed and personalized.

A holistic blended design studio model : Exploring and expanding learning opportunities

This book involves a comprehensive study of the learning environment by adopting Grounded Theory methodology in a qualitative comparative way.It explores the limitations and benefits of a face-to-face and a virtual design studio as experienced by architecture students and educators at an Australian university in order to find the optimal combination for a blended environment to enhance the students’ experience. The main outcome:holistic multidimensional blended learning model,that through the various modalities,provides adaptive capacity in a range of settings.The model facilitates learning through self-determination,self-management,and the personalisation of the learning environment. Another outcome:a conceptual design education framework,provides a basic tool for educators to evaluate existing learning environments and to develop new learning environments with enough flexibility to respond effectively to a highly dynamic and increasingly technological world.The provision of a practical framework to assist design schools to improve their educational settings according to a suitable pedagogy that meets today’s needs and accommodates tomorrow’s changes.

Workflow resource pattern modelling and visualization

Workflow patterns have been recognized as the theoretical basis to modeling recurring problems in workflow systems. A form of workflow patterns, known as the resource patterns, characterise the behaviour of resources in workflow systems. Despite the fact that many resource patterns have been discovered, people still preclude them from many workflow system implementations. One of reasons could be obscurityin the behaviour of and interaction between resources and a workflow management system. Thus, we provide a modelling and visualization approach for the resource patterns, enabling a resource behaviour modeller to intuitively see the specific resource patterns involved in the lifecycle of a workitem. We believe this research can be extended to benefit not only workflow modelling, but also other applications, such as model validation, human resource behaviour modelling, and workflow model visualization.

Dichotomy in the design studio 2.0 : adapting to new blended learning environments

In a study aimed at better understanding how students adapt to new blended studio learning environments, all undergraduate and masters of architecture students at a large school of architecture in Australia, learned a semester of architectural design in newly renovated, technology embedded, design studio environments. The renovations addressed the lessons learned from a 2011 pilot study of a second year architectural design studio learned in a high technology embedded prototype digital laboratory. The new design studios were purpose designed for the architecture students and adapted Student-Centred Active Learning Environment for Undergraduate Programs design principles. At the end of the semester, the students completed a questionnaire about their experiences of learning in the new design studio environments. Using a dual method qualitative approach, the questionnaire data were coded and extrapolated using both thematic analysis and grounded theory methodology. The results from these two approaches were compared, contrasted and finally merged, to reveal five distinct emerging themes, which were instrumental in offering resistance or influencing adaptation to, the new blended studio learning environments. This paper reports on the study, discusses the major contributors to resistance and adaptation, and proposes points for consideration when renovating or designing new blended studio learning environments. This research extends the 2011 pilot study by the same authors: ‘Dichotomy in the design studio: Adapting to new blended learning environments’.

Self-directed student work groups using blended learning

This paper provides a description of an innovative teaching approach designed to facilitate student work groups using a blended learning approach that incorporates both traditional face-to-face teaching methods and an online student work group facility. The teaching approach is designed to accommodate a large introductory human resource management subject positioned within an undergraduate business degree.

Dichotomy in the design studio : adapting to new blended learning environments

Since the architectural design studio learning environment was first established in the early 19th century at the École des Beaux-Arts in Paris, there has been a complete transformation in how the discipline of architecture is practiced and how students of architecture acquire information. Digital technologies allow students to access information instantly and learning is no longer confined to the rigid boundaries of a physical campus environment. In many schools of architecture in Australia, the physical design studio learning environments however, remain largely unchanged. Many learning environments could be mistaken for those last refurbished 30 years ago, being devoid of any significant technological intervention. While some teaching staff are eagerly embracing new digital technologies and attempting to modify their pedagogical approaches, the physical design studio learning environment is resistant to such efforts. In a study aimed at better understanding how staff and students adapt to new blended learning environments, a group of 165 second year architecture students at a large school of architecture in Australia were separated into two different design studio learning environments. 70% of students were allocated to a traditional design studio setting and 30% to a new, high technology embedded, prototype digital learning laboratory. The digital learning laboratory was purpose designed for the case-study users, adapted Student-Centred Active Learning Environment for Undergraduate Programs [SCALE-UP] principles, and built as part of a larger university research project. The architecture students attended the same lectures, followed the same studio curriculum and completed the same pieces of assessment; the only major differences were the teaching staff and physical environment within which the studios were conducted. At the end of the semester, all staff and students were asked to complete a questionnaire about their experiences and preferences within the two respective learning environments. The questionnaire response rate represented the opinions of 100% of the 10 teaching staff and over 70% of the students. Using a qualitative grounded theory approach, data were coded, extrapolated and compared, to reveal emerging key themes. The key themes formed the basis for in-depth interviews and focus groups of teaching staff and students, allowing the researchers to understand the data in more detail. The results of the data verified what had become increasingly evident during the course of the semester: an underlying negative resistance to the new digital studio learning environment, by both staff and students. Many participants openly exhibited a yearning for a return to the traditional design studio learning environments, particularly when the new technology caused frustration, by being unreliable or failing altogether. This paper reports on the study, discusses the negative resistance and explores the major contributors to resistance. The researchers are not aware of any similar previous studies across these particular settings and believe that it offers a necessary and important contribution to emergent research about adaptation to new digital learning environments.

Privacy-aware workflow management

Information security policies play an important role in achieving information security. Confidentiality, Integrity, and Availability are classic information security goals attained by enforcing appropriate security policies. Workflow Management Systems (WfMSs) also benefit from inclusion of these policies to maintain the security of business-critical data. However, in typical WfMSs these policies are designed to enforce the organisation’s security requirements but do not consider those of other stakeholders. Privacy is an important security requirement that concerns the subject of data held by an organisation. WfMSs often process sensitive data about individuals and institutions who demand that their data is properly protected, but WfMSs fail to recognise and enforce privacy policies. In this paper, we illustrate existing WfMS privacy weaknesses and introduce WfMS extensions required to enforce data privacy. We have implemented these extensions in the YAWL system and present a case scenario to demonstrate how it can enforce a subject’s privacy policy.

On structured workflow modelling

While there are many similarities between the languages of the various workflow management systems, there are also significant differences. One particular area of differences is caused by the fact that different systems impose different syntactic restrictions. In such cases, business analysts have to choose between either conforming to the language in their specifications or transforming these specifications afterwards. The latter option is preferable as this allows for a separation of concerns. In this paper we investigate to what extent such transformations are possible in the context of various syntactical restrictions (the most restrictive of which will be referred to as structured workflows). We also provide a deep insight into the consequences, particularly in terms of expressive power, of imposing such restrictions.

Reconstructing places and spaces in blended work integrated learning

This paper considers the emergence and ongoing development of an embedded, studentnegotiated work placement model of Work Integrated Learning (WIL) in the engineering and built environment disciplines at an Australian metropolitan university. The characteristics of the model and a continuous improvement strategy are provided. The model is characterised by large student cohorts independently sourcing and negotiating relevant work placements and completing at least one, mandatory credit-bearing WIL unit. Through ongoing analyses and evaluation of the model more experiential and collaborative learning approaches have been adopted. This has included the creation of blended learning spaces using technology. The paper focuses on the five year journey travelled by the teaching team as they embarked on ways to improve curriculum, pedagogy, administrative processes and assessment - effectively relocating much of their interaction with students online. The insights derived from this rich, single case study should be of interest to others considering alternative ways of responding to increasing student enrolments in WIL and the impact of blended learning in this context.

Air Gondwana and Mosswood Manor : blended learning environments utilising second life machinima to teach negotiation skills

Seminal reports into higher education in Australia and overseas have recognised negotiation as an essential skill of a practising lawyer and have recommended that all law schools include instruction in negotiation theory and practice in their curricula. Effective negotiation training includes the elements of instruction, modelling, practice and feedback. Ideally such training takes place in the context of small groups. However, this does not necessarily mean that negotiation cannot be taught effectively in the context of large groups. This paper discusses two related blended learning environments that provide instruction in negotiation theory and practice as part of the graduate capabilities program of the undergraduate law degree in the School of Law at the Queensland University of Technology in Brisbane, Australia. Air Gondwana, which forms part of the curriculum of the two first year Contract Law subjects, and Mosswood Manor, which forms part of the curriculum of the second year Trusts subject, utilise a common narrative concerning the family of a wealthy industrialist to facilitate learning of negotiation skills. The programs both combine online and in-class components, the online components utilising machinima (computer graphics created without the need for professional software) to depict the narrative. This strategy has enabled the creation of effective, engaging and challenging learning experiences for large cohorts of students studying by different modes (full-time, part-time and distance external). The use of a common narrative, including the same characters and settings, in the two programs also provides a familiar environment in which students advance their learning from one level of attainment to the next.

Examining workload models in online and blended teaching

Over the past decade, most Australian universities have moved increasingly towards online course delivery for both undergraduate and graduate programs. In almost all cases, elements of online teaching are part of routine teaching loads. Yet detailed and accurate workload data are not readily available. As a result, institutional policies on academic staff workload are often guided more by untested assumptions about reduction of costs per student unit, rather than being evidence-based, with the result that implementation of new technologies for online teaching has resulted in poorly defined workload expectations. While the academics in this study often revealed a limited understanding of their institutional workload formulas, which in Australia are negotiated between management and the national union through their local branches, the costs of various types of teaching delivery have become a critical issue in a time of increasing student numbers, declining funding, pressures to increase quality and introduce minimum standards of teaching and curriculum, and substantial expenditure on technologies to support e-learning. There have been relatively few studies on the costs associated with workload for online teaching, and even fewer on the more ubiquitous ‘blended’, ‘hybrid’ or ‘flexible’ modes, in which face-to-face teaching is supplemented by online resources and activities. With this in mind the research reported here has attempted to answer the following question: What insights currently inform Australian universities about staff workload when teaching online?
