Social Reasoning in Multi-Agent Systems with the Expectation-Strategy-Behaviour Framework

Multi-agent Systems (MAS) provide an increasingly relevant field of research due to their many applications to modelling real world situations where the behaviour of many individual, self-motivated, agents must be reasoned about and controlled. The problem of agent social reasoning is central to MAS, where an agent reasons about its actions and interactions with other agents. This is the most important component of MAS, as it is the interactions, cooperation and competition between agents that make MAS a powerful approach suited for tackling many complex problems. Existing work focuses either on specific types of social reasoning or general purpose agent practical reasoning - reasoning directed toward actions. This thesis argues that social reasoning should be considered separately from practical reasoning. There are many possible benefits to this separation compared to existing approaches. Principally, it can allow general algorithms for agent implementation, analysis and bounded reasoning. This viewpoint is motivated by the desire to implement social reasoning agents and allow for a more general theory of social reasoning in agents. This thesis presents the novel Expectation- Strategy-Behaviour (ESB) framework for social reasoning, which provides a generic way to specify and execute agent reasoning approaches. ESB is a powerful tool, allowing an agent designer to write expressive social reasoning specifications and have a computational model generated automatically. Through a formalism and description of an implemented reasoner based on this theory it is shown that it is possible and beneficial to implement a social reasoning engine as a complementary component to practical reasoning. By using ESB to specify, and then implement, existing social reasoning schemes for joint commitment and normative reasoning, the framework is shown to be a suitable general reasoner. Examples are provided of how reasoning can be bounded in an ESB agent and the mechanism to allow analysis of agent designs is discussed. Finally, there is discussion on the merits of the ESB solution and possible future work

Graduate Skills Assessment : Stage One Validity Study

The Graduate Skills Assessment (GSA) is a new test with complex aims and is in the first stages of development and application. Principally, the test aims to assess a set of valued and widely applicable generic skills that may be developed by the university experience and which are relevant to university achievement and graduate work. This publication reports on the validity of the first stage of the Graduate Skills Assessment test (GSA Stage One Validity Study), which covers the first two tests, Exit 2000 and Entry 2001. These tests involved the participation of 3663 students drawn from nine broad fields of study across 27 Australian universities. Details of these populations are given in the GSA Summary Reports (Hambur & Glickman, 2001, Hambur & Le, 2001). The study was commissioned by the Commonwealth Department of Education, Training and Youth Affairs

Attitudinal and behavioural determinants influencing decision makers when adopting integration technologies in local government

Over the last few years, the advent of innovative or revolutionary integration technologies has influenced pivotal decisions within top management to strategically transform Local Government Authorities (LGAs). These technologies may represent a huge cost for adopting LGAs, but may also offer the chance to achieve competitive advantage through superior service delivery. With the emergence of electronic Government (e- Government), LGAs are turning to integration technologies to fully automate and e-enable their business processes and integrate their IT infrastructures. While prior research on the adoption of integration technologies in the private and public domain has considered several determinants (e.g. benefits, barriers, costs), little attention has been given to investigate the attitudinal and behavioural determinants influencing top management’s decision making process for the adoption of integration technologies in LGAs. Notwithstanding, the implications of this research have yet to be assessed, leaving scope for timeliness and novel research. Therefore, it is of high importance to investigate this area within LGAs and contribute to the area of strategic decision making by examining attitudinal and behavioural determinants of top management in relation to integration technologies adoption

The development of project management capability in complex organisational settings: towards a knowledge-based view

This exploratory case-based study investigates the development of project management (PM) as an organisational capability in two public sector organisations (PSO) during a period of rapid environmental change. Within the PM literature, the concept of project management capability (PMC) and how it develops over time through organizational learning is still an emerging tradition led to date by mainly European scholars (Lindkvist, Söderlund, Davies, Brady, Hobday, etc.). This investigation locates itself within this emerging tradition and represents a unique empirical opportunity to study the learning processes involved in PMC development in a complex setting that shows these processes in greater relief. In both of the organizations studied, the elevation and enhancement of PMC from a relatively low-level activity to a strategic supporting competence was triggered by radical and rapid change in the external environment during the 2000s. The main process insight is that PMC is found to be developed as a dynamic organisational capability in complex PM settings through organisational complex problem-solving (CPS). The overall outcomes of the study build upon and extend the emerging PMC literature in at least three important respects, with implications for traditional PM research and practice. Firstly, in contrast to the mechanistic view of traditional PM, this study supports an integrated knowledge-based view of ‘projects as process’ and ‘PM as practice’. In this view, a project is seen to be ‘a mode of organising to accomplish a temporary undertaking’ and PMC is seen as a strategic organisational practice in organising complex projects. Secondly, PMC is honed as a practice through goal-directed organisational CPS. This builds upon and extends the work of Popper on the evolutionary growth of knowledge by revealing problemsolving as a two-stage process of differentiation-integration, or disorder-order. In contrast to traditional PM which follows a path from ‘order to order’, the development of PMC as an organisational capability is found to proceed from ‘order to disorder to order’. Thirdly, using the lens of PM as practice, a 'distributed organising' approach is suggested for coordinating the formation of ‘complex knowledge’ under organisational CPS, which is inherently emergent and dynamic. This contrasts with the ‘centralised planning’ approach of traditional PM, which assumes that knowledge is manifest in pre-given plans that are executed with little organisational learning expected beyond the application of prior knowledge

The response of secondary students from non-English speaking backgrounds to a visual arts course

Interest in multiculturalism has been expressed by educators for a number of years. Much of the literature concerning multiculturalism in visual arts education calls for the adoption of a culturally inclusive curricula in order to meet the needs of all students. In his consideration of conceptions of curriculum, Eisner (1988) made reference to a preferred body of knowledge which often excludes students from minority groups within society. Many Australian schools are experiencing increases in enrolments of students from non-English speaking backgrounds (NESB). These students may themselves be immigrants or the children of one or both parents born in another country. This study is concerned specifically with the impact of such students\u27 inherited culture on their perceptions of the visual arts which may be influenced by exposure to particular styles or forms of art experienced in the context of the family, or through visual arts education in the student\u27s country of origin. The research investigates students from non-English speaking backgrounds perceptions of the visual arts and visual arts education. The study\u27s purpose is to determine the degree to which these perceptions influence the performance of NESB students undertaking a visual arts course at upper secondary school level. Although many students from various ethnic groups show an interest in and aptitude for the visual arts, they are often not successful in all aspects of the secondary level. From equity and justice perspectives it would appear that the opportunity to succeed in a chosen area should be available to all students and that in order to provide this opportunity, it is necessary to determine what factors influence the success or failure of these students. This study involved the use of qualitative research methods and was conducted as a case-study. The sample or case was selected from a Year 11 tertiary entrance art class and represents a diversity of ethnic backgrounds. The seven participants originated from Australia, mainland China, Greece, Indonesia, Russia and Vietnam. The data was collected using a questionnaire, interviews, observation and examination of work samples. The data was categorised according to themes which emerged during the data collection and analysis stages. Results showed that NESB students appear to be influenced by their early home and educational experiences and that these in turn are influenced by the ethnic and cultural contexts in which they were experienced. There is also evidence that the delivery and content of visual arts education plays an important role in influencing students\u27 perceptions of the visual arts. Information emerging from the study however suggests a need for further research in order to validate the findings. Replication of this research using a wider sample of students may help to reduce some of the variables impacting on the study. These may include levels of literacy attained by students in both their mother tongue and in English, continuity experienced by students in both general and visual arts education, and socio-economic status. Whilst it appears that further use of the case study may be appropriate, variation in both the research design and research instruments should also be considered

Towards automated composition of convergent services: a survey

A convergent service is defined as a service that exploits the convergence of communication networks and at the same time takes advantage of features of the Web. Nowadays, building up a convergent service is not trivial, because although there are significant approaches that aim to automate the service composition at different levels in the Web and Telecom domains, selecting the most appropriate approach for specific case studies is complex due to the big amount of involved information and the lack of technical considerations. Thus, in this paper, we identify the relevant phases for convergent service composition and explore the existing approaches and their associated technologies for automating each phase. For each technology, the maturity and results are analysed, as well as the elements that must be considered prior to their application in real scenarios. Furthermore, we provide research directions related to the convergent service composition phases

Human-Robot Collaborations in Industrial Automation

Technology is changing the manufacturing world. For example, sensors are being used to track inventories from the manufacturing floor up to a retail shelf or a customer’s door. These types of interconnected systems have been called the fourth industrial revolution, also known as Industry 4.0, and are projected to lower manufacturing costs. As industry moves toward these integrated technologies and lower costs, engineers will need to connect these systems via the Internet of Things (IoT). These engineers will also need to design how these connected systems interact with humans. The focus of this Special Issue is the smart sensors used in these human–robot collaborations

Same same but different - Towards a taxonomy for digital involvement projects

Governments and public institutions increasingly embrace digital opportunities to involve citizens in public issues and decision making. While public participation is generally seen as an important and promising venture, the design of the participation processes and the utilized digital infrastructure poses challenges, especially to the public sector. Instead of limiting conceptual guidance and exchange to one domain, we therefore develop a taxonomy for digital involvement projects that unites the domains of e-participation, citizen science and crowd-X. Embedded in a design science research approach, we follow an iterative design process to elaborate the key characteristics of a digital involvement project based on the participation process, its individuals and digital infrastructure. Through evaluating the artifact in a focus group with domain practitioners, we find support for the usefulness of our taxonomy and its ability to provide guidance and a basis for discussion of digital involvement projects across domains
