Forest management policy decisions are complex due to the multiple-use nature of goods and services from forests, difficulty in monetary valuation of ecological services and the involvement of a large number of stakeholders. Multi-attribute decision techniques can be used to synthesise stakeholder preferences related to regional forest planning because it can accommodate conflicting, multidimensional, incommensurable and incomparable objectives. The objective of this paper is to examine how the Analytical Hierarchy Process (AHP) can be used to incorporate stakeholder preferences in determining optimal forest land-use choices. The Australian Regional Forest Agreement Programme is taken as an illustrative case for the analysis. The results show that the AHP can formalise public participation in decision making and increase the transparency and the credibility of the process.

The link between management practices and worker’s motivations impacting construction productivity is being considered as significant among the research community. This research aimed to identify and analyse the underlying attributes impacting construction productivity from the site management perspective. This research presents a framework designed to analyse and quantify the relative relevance of different drivers in the determination of productivity levels and the degree of effectiveness of potential opportunities for improving performance of overall projects. Owing to the complexity of construction projects and underlying conflicting drivers influencing higher worker’s productivity, the Analytical Hierarchy Process (AHP) is employed to deal with interdependent relationships within a multi-criteria decision-making model. In the analytical approach, the large unstructured decision parameters are identified first and then are broken down into the manageable and measurable components using a top down hierarchical structure. This paper demonstrates an example to illustrate how to empirically analyse and prioritise a set of influencing parameters as selection criteria in devising appropriate management practices to ensure higher productivity vis-à-vis optimum performance of projects.

Australian agriculture is very susceptible to the adverse impacts of climate change, with major shifts in temperature and rainfall projected. In this context, this paper describes a research methodology for assessing potential climate change impacts on, and formulating adaptation options for, agriculture at regional level. The methodology was developed and applied in the analysis of climate change impacts on key horticultural commodities—pome fruits (apples and pears), stone fruits (peaches and nectarines) and wine grapes—in the Goulburn Broken catchment management region, State of Victoria, Australia. Core components of the methodology are mathematical models that enable to spatially represent the degree of biophysical land suitability for the growth of agricultural commodities in the region of interest given current and future climatic conditions. The methodology provides a sound analytic approach to 1) recognise regions under threat of declines in agricultural production due to unfolding climatic changes; 2) identify alternative agricultural systems better adapted to likely future climatic conditions and 3) investigate incremental and transformational adaptation actions to improve the problem situations that are being created by climate change.

Monitoring patients who have noncommunicable diseases is a big challenge. These illnesses require a continuous monitoring that leads to high cost for patients' healthcare. Several solutions proposed reducing the impact of these diseases in terms of economic with respect to quality of services. One of the best solutions is mobile healthcare, where patients do not need to be hospitalized under supervision of caregivers. This paper presents a new hybrid framework based on mobile multimedia cloud that is scalable and efficient and provides cost-effective monitoring solution for noncommunicable disease patient. In order to validate the effectiveness of the framework, we also propose a novel evaluation model based on Analytical Hierarchy Process (AHP), which incorporates some criteria from multiple decision makers in the context of healthcare monitoring applications. Using the proposed evaluation model, we analyzed three possible frameworks (proposed hybrid framework, mobile, and multimedia frameworks) in terms of their applicability in the real healthcare environment.

Information quality is a complex problem. Issues relating to information quality are strongly embedded in the context of the operations of information systems. Information quality issues, therefore, have qualitative as well as quantitative underpinnings, which affect on the various dimensions of information quality. In order to improve information quality, it is essential to assess its various dimensions. This assessment provides the gaps that work as the building blocks for improving quality of information. However, assessing information quality dimensions is extremely intricate because each dimension depends upon other dimensions, which makes it difficult to objectively assess these dimensions. This research utilizes a product perspective of information and applies Six-Sigma methodology to assess information quality. It describes a case study of a Korean manufacturing organization where analytical hierarchy process and quality function deployment was utilized to determine the mutual relationships of information quality dimensions and critical to information quality factors.

This thesis is a case study of educational process in the leadership development program of the Australian Defence Force Academy. The intention is to determine the relative emphasis in educational process on the conventional command and managerial compliance (Type A) style and the emergent contingent and creative (Type B) style of leadership. The Type A style is theorised as emphasizing hierarchy and control, whereas the emphasis in a Type B style is on adaptive and entrepreneurial behaviour. This study looks at the learning process in a cultural and structural context rather than focus on curriculum and instructional design. Research in this wider context is intended to enable development processes to successfully bridge a gap between theory and practice, implicit in studies that identify theories 'in-operation' as different from the theories 'espoused' (Argyris 1992, Savage 1996). In terms of espoused and in-use theory, the study seeks to produce a valid and reliable result to the question: what is the relative emphasis on the two leadership styles in the operation of the three educational mechanisms of curriculum, pedagogy (teaching practice) and assessment? The quantitative analysis of results (n = 114) draws attention to both leadership styles in terms of two and three-way relationships of style, cadet or work group and service type. The data shows that both Type A and Type B leadership styles are evident in the general conversation of the organisation. This trend is present as espoused theory in the curriculum of the Defence Academy. However, the data also confirm a clear and strong emphasis towards command and managerial compliance as theory-in-use, particularly by cadets. This emphasis is noticeably evident in the teaching and assessment practice of the Defence Academy. Other research outcomes include the observation that: Contextually, while studies show it is difficult to isolate skills from their cultural and biographical context (Watkins, 1991:15), this study suggests that it is equally difficult to isolate skills development from this context. There is a strong task or instrumental link identified by cadet responses in terms of content and development process at the Defence Academy, in contrast to the wider developmental emphasis in general literature and senior officer interviews. There is a lack of awareness of teaching strategies and development activity consistent with espoused Type B leadership theory and curriculum content. This gap is compounded by the use in the Defence Academy of personnel without teaching expertise or suitable developmental experience. The socialisation of cadets into the military workplace is the primary purpose of training. This purpose appears taken for granted by all concerned - staff, cadets and senior officers. Defence Academy development processes appear to be faced with a dilemma. Arguably, training and learning from experience are limited approaches to development. Training, which involves learning by replication, and learning from experience, which is largely imitative, are both of little use when people are faced with novel and ambiguous situations. This study suggests that in order to support the development of capabilities that go beyond training based competence a learning and development approach is needed. This more expansive approach requires educational planners to consider the cultural and social context that can inadvertently promote the status quo in practice over espoused outcomes.

Anomaly detection as a kind of intrusion detection is good at detecting the unknown attacks or new attacks, and it has attracted much attention during recent years. In this paper, a new hierarchy anomaly intrusion detection model that combines the fuzzy c-means (FCM) based on genetic algorithm and SVM is proposed. During the process of detecting intrusion, the membership function and the fuzzy interval are applied to it, and the process is extended to soft classification from the previous hard classification. Then a fuzzy error correction sub interval is introduced, so when the detection result of a data instance belongs to this range, the data will be re-detected in order to improve the effectiveness of intrusion detection. Experimental results show that the proposed model can effectively detect the vast majority of network attack types, which provides a feasible solution for solving the problems of false alarm rate and detection rate in anomaly intrusion detection model.
