Execution Pattern

This article presents a comparator module which aims to compare, in real time, executions of organizational transactions with patterns of behaviors of these transaction executions, allowing the determination of which execution pattern is being followed by running each transaction. This is according to information received by the internal control mechanisms, which continuously monitors the transaction executions. A possible application using this module was deployed and results were obtained from a case study. The results prove effectiveness of the module, mainly because it is able to assess business compliance and the qualitative risk associated to each transaction execution while it is running, enabling an efficient continuous auditing application. The innovation of this article is ensured by the use of an ontological model to represent organizational transactions, which can be applicable to any type of transaction in any business area in order to audit transactions at a very low level, contrary to what happens in traditional auditing, which occurs at a high level (e.g. compare whether a completed transaction has followed a set of procedures). Besides the conceptualization, this work presents some technical details of development and discussion of results from the case study.

In this article, we present WOAD, a framework that was inspired and partly validated within a 2-year observational case study at a major teaching hospital. We present the WOAD framework by stating its main and motivating rationales, outlining its high-level architecture and then introducing its denotational language, LWOAD. We propose LWOAD to support users of an electronic document system in declaratively expressing, specifying and implementing content- and event-based mechanisms that fulfill coordinative requirements and make users aware of relevant conditions. Our focus addresses (a) the user-friendly and yet formal expression of local coordinative practices based on the work context; (b) the promotion of awareness of both these conventions and the context to enable actors to quickly respond; (c) the full deployment of coordination-oriented and context-aware functionalities into legacy electronic document systems. We give examples of LWOAD mechanisms taken from the case study and discuss their impact from the EUD perspective.

Simulation Environments

NATO and the nations use distributed simulation environments for various purposes, such as training, mission rehearsal, and decision support in acquisition processes. Consequently, modeling and simulation (M&S) has become a critical technology for the coalition and its nations. Achieving interoperability between participating simulation systems and ensuring credibility of results currently often requires enormous effort with regards to time, personnel, and budget. Recent technical developments in the area of cloud computing technology and service oriented architecture (SOA) may offer opportunities to better utilize M&S capabilities in order to satisfy NATO critical needs. A new concept that includes service orientation and the provision of M&S applications via the as-a-service model of cloud computing may enable composable simulation environments that can be deployed rapidly and on-demand. This new concept is known as M&S as a Service (MSaaS). There has also been the recent emergence of containerization as an alternative to virtualization. Containerization is the process of creating, packaging, distributing, deploying, and executing applications in a lightweight and standardized process execution environment known as a container. Because containers are, in principle, lightweight, they are suitable to serve as the vehicle for the provision of packaged (micro)services. Service orientation is an approach to the design of heterogeneous, distributed systems in which solution logic is structured in the form of interoperating services. This paper investigates various aspects of service orientation and containerization including simulation composition, networking, discovery, scalability, and overall performance. This investigation provides background information on the topics of service orientation, containerization, and Docker – a technology ecosystem for working with containers. A case study is presented for the use of Docker in support of a training simulation based on the high level architecture (HLA). The HLA is an IEEE standard architecture for distributed simulation environments that was originally developed for defense applications. The case study introduces a number of training use cases, and shows how Docker can be used to assist in their implementation. The performance impact of running a simulation within container technology is also investigated. The application of container technology to HLA-based simulations as presented in this paper is novel. The motivation for looking at this topic stems from the activity being conducted within NATO MSG-136.

<span>Teleteaching, though in a relatively early stage at Monash University, has the potential to provide a conduit for high level interaction between students and staff on various campuses in 'real time'. Whilst the technology holds valuable potential, there are unresolved discrepancies between 'what can be done' and the academics' understandings and common practice of 'what is actually being done' with teleteaching. It is only through research into current practices and attitudes that an understanding will be gained of the strategies that need to be adopted to ensure that teleteaching becomes an enriching learning experience for staff and students alike.</span><p>This article focuses on the perceptions and practices of staff within the realm of current training and support. It aims to provide an understanding of difficulties experienced in the use of teleteaching, and to suggest solutions emerging from the research. To illustrate current practices and attitudes towards the use of teleteaching, this paper reports on a study conducted by Tennant (1997) into the use of teleteaching at Monash University to deliver lectures between two campuses. The paper concentrates on andragogical, interaction and training issues in teleteaching with large groups of students as seen through the eyes of both academic staff and students.</p>
