Interlink decision making index (IDMI) -- a simple tool/concept to assist decision making for sustainability Part 1: definition of IDMI

There is an apparent gap between the LCA or other assessment's outcomes and its effective application in the decision making process. It is needed to provide to the decision makers a simple, less human interfered mechanism that integrates all the key criteria (environmental, economic, technical and safety etc.). The proposed index: Interlink Decision Making Index (IDMI) has all these features: simple, interlink (all criteria) and automatically and quantified influence of critical criteria (ie. no human weighting needed) and is able to assist the multi-criteria decision making for sustainability based on the outcomes of specific assessments (eg. LCA, ElA etc.). The index represents a pure numerical value and does not necessarily have any physical meanings, but it reflects the total merits of a particular option once the normal decision making criteria and (up to two) critical criteria (CC) have been chosen. Then, without arbitrarily weighting process, the comparison and selection of the best possible option, ie. decision can be made based on the derived IDMI results. Two hypothetical examples are presented in part 2 of the paper to demonstrate the application of the IDMI concept and it's differences with the traditional "tabular method" in the decision making process.

One-dimensional nanomaterials synthesized using high-energy ball milling and annealing process

One-dimensional (1D) nanomaterials including nanotubes, nanowires and nanorods have many new properties, functionalities and a large range of promising applications. A major challenge for these future industrial applications is the large-quantity production. We report that the ball milling and annealing process has the potential to achieve the mass production. Several examples including C, BN nanotubes and SiC, Zn nanowires are presented to demonstrate such capability. In addition, both size and structure of 1D nanomaterials can be controlled by varying processing conditions. New growth mechanisms involved in the process have been investigated and the high-energy ball milling has an important role in the formation of these 1D nanomaterials.

Effects of starvation and water quality on the purging process of farmed Murray cod ( Maccullochella peelii peelii )

The aim of this study was to determine the effects of starvation and water quality during the purging process on the biometric parameters, fatty acids, and flavor volatiles of Murray cod farmed in a recirculation system. Market size Murray cod, at the end of the grow-out stage, were divided into eight treatments. The treatments were either fed/starved (F or S) and kept in clean water (CW: CWF2, CWS2, CWF4, and CWS4) or fed/starved and kept in recycled water (RW: RWF2, RWS2, RWF4, and RWS4) for either 2 or 4 weeks. Fish were sampled at 0, 2, and 4 week intervals. Food deprivation was responsible for a significant (P < 0.05) weight loss compared to that of fed treatments. The same was observed for the condition factor (K), hepatosomatic index (HSI), and dress-out percentage (DP). No significant changes were, however, observed in the visceral fat index (VFI). Saturated fatty acids (SFA) were highest in RWF4 and lowest in CWS4 (P < 0.05), while monounsaturated fatty acids (MUFA) were lowest in CWF4 (P < 0.05). Starvation did not affect the flavor volatile compounds, which were mainly affected by changes in water quality. Specifically, total aldehyde (% w/w) content was significantly (P < 0.05) affected by water quality, but the time of purging was not responsible for any noteworthy differences. This study was able to separate the effects of starvation and water quality, in the purging process, on the final eating quality of farmed market size Murray cod. It is concluded that because of the inevitable weight loss during starvation, Murray cod should be fed during the purging stage but kept in clean water and deprived of food only for the time necessary to empty the gastro-intestinal tract.

Internationalisation process for construction design service SMES on multi national projects

The internationalisation process has four key factors including market selection, decision to enter, entry modes and factors affecting entry modes. Small and medium sizes enterprises (SMEs) in the architectural engineering construction design services sector have demonstrated an increasing involvement in international markets. Consequently, activities and processes involved in internationalisation of these SME types present important issues for understanding from entrepreneurial, managerial and research perspectives. A research gap exists, however, through emphasis in past research having been given to large firms, and in particular those within manufacturing. This investigation identified similarities and differences between two construction design service SMEs who have been exporting to various localities including Eastern Europe, Africa, Middle East, UK, Asia and South America for typically more than two decades. Similarities and differences were identified within eight major constructs including: purpose, firm type, market image and design philosophy, entry mode strategy, institutional arrangement, factors affecting mode of entry, marketing selection and firm strategy in relation to project selection. The primary reasons for firms in both cases working in international markets were associated with the firms' motivations related to growth and enhancement of financial viability. Both firms were categorized as client following. This paper discusses the various internationalization processes and explains the reasons intrinsic to each case study. The two firms have been highly successful in the internationalization processes on multi-national projects die to a reflexive capability philosophy which incorporates continuous analysis and alignment between firm and locality characteristic to transform traditional barriers into enablers of success.

Developing and validating a questionnaire to measure spirituality : a psychometric process

The purpose of the paper is to describe the processes undertaken to evaluate the psychometric properties of a questionnaire developed to measure spirituality and examine the relationship between spirituality and coping in young adults with diabetes.

The specific validation processes used were: content and face validity, construct validity using factor analysis, reliability and internal consistency using test-retest reliability and Cronbach’s alpha correlation coefficient.

The exploratory factor analysis revealed four factors: self-awareness, the importance of spiritual beliefs, spiritual practices, and spiritual needs. The items on the Spirituality Questionnaire (SQ) revealed factor loading ≥ 0.5. Reliability processes indicated that the SQ is reliable: Cronbach’s alpha 0.94 for the global SQ and between 0.80-0.91 for the four subscales. Test-retest statistic examination revealed stability of the responses at two time points 10 weeks apart.

The final questionnaire consists of 29 items and the psychometrics indicated that it is valid and reliable.

Whey protein and gum arabic encapsulated Omega-3 lipids. The effect of material properties on coacervation

The effect of material properties on complex coacervation of whey protein and gum Arabic from various sources was investigated. In this study, it was demonstrated that material properties of whey protein isolates and gum Arabic affect the complex coacervation process significantly. For whey protein, the coacervation capability could be correlated with their level of denaturation and calcium content. For gum Arabic, both material sources and salt content were found to be attributing factors to their coacervation capability. This study facilitated the development of Omega-3 lipids microcapsules with promising performances in certain food applications.

Biometric, nutritional and sensory characteristic modifications in farmed Murray cod (Maccullochella peelii peelii) during the purging process

Intensively farmed, market-size Murray cod (~ 600 g), were purged (transferred into a clean water system and starved) and sampled at three day intervals for a total of 18 days (D0, D3, D6, D9, D12, D15 and D18). Purged fish lost from 6% (D3) to 14% (D18) body weight, and the weight loss was highly correlated to the number of days of purging/starvation. Condition factor and Hepatosomatic Index decreased significantly (P < 0.05) only after 18 days of purging compared to the control (D0). Fillet lipid content (%) did not vary during the trial. Eicosapentaenoic acid (EPA: 20:5 n−3) decreased and docosapentaenoic acid (DPA: 22:5 n−3) increased (P < 0.05) during the trial, while docosahexaenoic acid (DHA: 22:6 n−3) did not show any significant variation. Purging contributed positively to the improvement of the volatile flavour compound composition, with a significant (P < 0.05) reduction in total volatile aldehydes and an increase in total volatile hydrocarbons. Since no major differences were found between samples during the last stages of the purging process (D12, D15 and D 18), it is possible to conclude that, under these experimental conditions, 12 days is the minimum duration to obtain an improvement in the volatile compound profile of intensively farmed Murray cod whilst keeping body weight loss to a minimum.

Adopting reflexive capability in international briefing

Purpose – The aim of the paper is to investigate the architectural firm's role in the briefing process on international projects and to identify the strategies of successful firms to overcome barriers.

Design/methodology/approach – A model is developed based on a critique of briefing models and international design management theory. The development of a reflexive capability model borrows cultural theory concepts of capital and reflexivity. The model is based on maximizing reflexive capability through the management of social, cultural and intellectual capital. Two case studies of architectural firms identify barriers during the briefing process and strategies to overcome these barriers. Data collection involved 16 interviews with senior management and design team staff.

Findings – There are various barriers and strategies used to achieve success in the briefing process. However, the management of a firm's capital is key to successful briefing on international projects and is a characteristic of reflexive practice. Reflexivity is based in a positive interpretation of change, and a continual responsiveness to change by participants in a system. The study provides useful information on management of the design and briefing stages of international projects.

Research limitations/implications – The study is limited by the number of case studies used and the difficulty of generalisability of findings.

Practical implications – The research is that it provides useful information about how to approach constant change during briefing for the architects and clients who work on international projects.

Originality/value – The model is original and has value as it assists in explaining why some firms are more successful than others. The case studies provide new knowledge on international projects and the briefing process. The value of the paper is for the academic community, professionals in the built environment and clients involved in international projects.

The role of reflexive capability in relation to intellectual capital on multi international partnerships

This paper reports the results of an analysis of five Malaysian firms who have worked successfully on multi international partnerships and/or megaprojects. A case study methodology was employed to examine the barriers and successful strategies the firms used in decision making in various international markets. A common characteristic across the firms was the ability to self reflect and adapt their practices to different international conditions despite numerous differences between countries including cultural, social, project governance structures, regulatory, terminology and codes. A reflexive capability model developed from the social sciences theory of individual agent reflexivity was developed to explain the way in which firms as an entity can develop awareness, responsiveness and adaptability for long term success in diverse international markets. This paper builds upon an initial Australian study which developed the model grounded in empirical observations of internationalising design construction firms by presenting the results of a second study of Malaysian firms. Results indicate that the model of reflexivity capability is a useful way to interpret practices that are undertaken in multi partner relationships on larger more complex projects. Successful Malaysian firms within joint venture relationships display an ability to self reflect and adapt. This transformation process is critiqued in relation to the relationships between social, cultural and intellectual capital. Reflexive capability is a characteristic of the successful case study firms working within global models of practice. The reflexive capability model is explained in relation to common themes identified in relation to the management of intellectual capital in successful multi international partnerships and megaprojects.

Design management methodology to strengthen firm and industry competitiveness in the construction design services export sector

The aim of this research was to investigate strategies deployed by successful construction design-related firms towards achieving high levels of firm competitiveness in international markets. A reflexive capability model, developed through a critical analysis of related internationalisation literature, is composed of three key areas; internationalisation process, market knowledge and design management. Firm reflexive capability is explored through the management of social, cultural and intellectual capital. The concept of reflexivity is borrowed from sociology. Reflexivity is reinterpreted as the ‘firm’s’ ability to be aware, responsive and adaptable to self, market and project needs assessment. A cross case analysis explored the barriers and success factors through three constructs; internationalisation process, design management and market knowledge of three firms. This paper demonstrates that international firm competitiveness is dependent upon the strategic inter-relational management of social, cultural and intellectual capital for maximum advantage of the utilisation and leverage of one form of capital to gain another. This leads to the development of increasing reflexive capability to support internationalisation. An outcome of this research is the identification of the central relation between a level of reflexive capability within the firm and the firm’s level of success in international markets. This research is part of an ongoing program of research on international collaborative practice. A Reflexive Capability Matrix was developed from the findings of one research project and then validated through a second research project (only the capability matrix is presented in this paper though). The reflexive capability approach is appropriate to all firms but what is speculated upon is that the reflexive capability is particularly intrinsic to small to medium sized construction design firms who work globally. A reflexive capability is a characteristic of successful and innovative firms internationalising and working within global models of practice.

The development of a theoretical model for firm design management to support internationalisation processes

The aim of this research was to investigate strategies deployed by successful construction design related firms towards achieving high levels of firm competitiveness in international markets. A reflexive capability model, developed through a critical analysis of related internationalisation literature, is composed of three key areas; internationalisation process, market knowledge and design management. Firm reflexive capability is explored through the management of social, cultural and intellectual capital. The concept of reflexivity is borrowed from sociology the philosophers, Bourdieu and Giddens. Reflexivity is reinterpreted as the ‘firm’s’ ability to be aware, responsive and adaptable to self, market and project needs assessment. This research is part of an ongoing program of research on international collaborative practice. A Reflexive Capability Matrix is proposed. The reflexive capability approach is appropriate to all firms but what is speculated upon is that the reflexive capability is particularly applicable to small to medium sized construction design firms who work globally. A reflexive capability is a characteristic of successful and innovative firms internationalising and working within global models of practice. This paper is the theoretical development to support the paper in this congress “Design Management Methodology to Strengthen Firm and Industry Competitiveness in the Construction Design Services Export sector” where the methodology and results of a cross case analysis of three construction design firms are presented.

Multi-market industrial organizational economic models for the internationalization process by small and medium enterprise construction design service firms

Small and medium enterprises (SMEs) are critical to strategic initiatives in an economy; however, their contribution to foreign trade is not as significant. SMEs are one of the principal driving forces in economic development. One of the greatest challenges is the internationalization process for longevity rather than seeing the process as initial market entry. The internationalization process research has typically involved four key constructs: market selection, decision to enter, entry modes and factors affecting entry modes. Past research has focused on large manufacturing firms. The export of architectural, engineering and construction (AEC) firms has undergone growth, yet there is still significant opportunity for further growth. The majority of AEC firms are SMEs. Notwithstanding assistance provided through international trade missions, organized export firm support networks and information packages by a burgeoning number of government agencies, there are still perceived barriers to market entry and long-term economic sustainability for SMEs. There are a number of problems faced by SMEs acting in foreign trade. This investigation explores the successful initial internationalization process constructs and identifies unique project-oriented sector characteristics. The study identified similarities and differences between two firms that have been exporting to various localities, including Eastern Europe, Africa, Middle East, UK, Asia and South America, for more than two decades. The similarities and differences were identified within eight major constructs: purpose, firm type, market image and design philosophy, entry mode strategy, institutional arrangement, factors affecting mode of entry, market selection and firm strategy in relation to project selection. The primary reasons for internationalization were associated with the firms' motivations related to growth and financial viability. This article discusses the various internationalization processes and strategies intrinsic to each case study and establishes a detailed set of empirical observations from which to develop further a grounded theoretical model of reflexive capability for the internationalization process. This study contributes to the body of knowledge around the SME AEC design service firm's internationalization process, as a dynamic, evolving and continuously adaptable construct for project-based sectors.
