Decision making to support an integrated infrastructure supply chain industrial ecological approach within public private partnerships

Supply chains are complex adaptive systems for which final performance depends upon numerous interdependent decisions made by numerous firms which synthesise inputs from various resources systems.  The dynamic interdependent behaviour of social, economic, material and informational resource systems within eco-industrial settings that support the built environment life cycle supply chains can be studied at the supply chain level.  The impact of megaprojects is significant and holds promise to explore the impact of decisions on various systems as it combines project and system boundaries.  Megaoprojects considered as major events within systems can produce critical revolutionary impacts on the systems within which they are embedded.  The decisions that are made on megaprojects are central to risk management.  typically major infrastructure projects are procured through a form of public private partnership (PPP).  The core principle of PPP is value for money which refers to the best available outcome attempting to take account of all benefits, costs and risks over the whole life of the procurement.  In this paper the focus is on Australia where there has been considerable acitivity in the use of PPPs.  With recent national infrastucture packages proposed to stimulate the economy due to the global financial crisis, decision modelling on risks is a revelant and critical matter not only in practice but also in the research community.  PPPs encourage the whole-of-lifecycle approach in the procurement and management of public sector assets by transparently recognising the costs and risks associated with the whole life of the required service or facility, thus integrated whole of life supply chains can be considered.  By creating a single point of responsibility for an entire project from inception through operation, a strong incentive is created for thinking about the effects that a design or construction decision will have on the effectiveness and efficiency of managing and maintaining a facility during its operational life.  The decision to procure holistic supply chains becomes a much more viable commercial reality in the PPP environment than previously considered in the usual commercial construction spot transactional approach.  These types of decisions tend to be imprecise, approximate and complex requireing justification and reasoning logic rather than the classical 'truth' logic.  The purpose of this paper is to develop a theoretical decision framework which combines interdependency and multi-values logic for supply chain procurement modelling.

Promoting energy efficiency in the private rented sector

The English House Condition Survey for 1991 demonstrated that levels of energy efficiency in private rented property are significantly below other sectors, even though energy improvements have tangible benefits for landlords. The low level of energy efficiency provision in the private rented sector indicates that landlords are unaware or unconvinced of these benefits and market barriers may have restricted uptake. Information regarding energy efficiency advice to the private rented HMO sector has focussed on offering good practice design guidance, and information about the level of fitness and overall characteristics of the sector. This research project evaluated the PRESS scheme, which encouraged landlords to introduce energy efficiency measures. A total of 78 private sector rented properties in Sheffield were analysed with retrofit measures to improve levels of energy efficiency. The results demonstrate that whilst market barriers exist, the PRESS scheme went some way to overcoming some barriers to energy efficiency.

Risk allocation in public-private partnership projects : an innovative model with an intelligent approach

Both the increasing private participation in public projects and the critical importance of appropriate risk allocation to the success of Public-private partnership (PPP) projects justify specific research on how to establish effective risk allocation strategies in PPP projects. Partner’s risk management capability is currently the main concern to risk allocation in PPP projects. Following the transaction cost economics, it is argued that factors such as partner’s commitment and risk management structure should be considered simultaneously in order to develop effective risk allocation strategies. Based on the holistic capability-commitment governance-driven view, this paper proposed a model for generating an optimal risk allocation strategy in PPP projects. The model is demonstrated and described. An artificial intelligent technique integrated with fuzzy logic for model testing and validation is then introduced and justified. The innovative model is expected to provide a logical and complete understanding of the risk allocation strategy selection process, and to provide stakeholders with a richer framework than previously existing ones to guide their decision-making on risk allocation strategies.

A construct of the 'ethos of codes of ethics' (ECE) : the case of private and public Sweden

Purpose – The objective of this paper is to develop and describe a construct of the “ethos of the codes of ethics” (i.e. an ECE construct) in the private and public sectors of Sweden.

Design/methodology/approach – The paper takes a cross-sector approach to codes of ethics amongst the top private sector companies and the top public sector organisations. The paper then examines the measures put in place by the dual sample in order to describe the ethos of their codes of ethics.

Findings – The multivariate techniques used in the statistical analysis indicated that the ECE-construct consists of five dimensions: ethical bodies, ethical tools, ethical support procedures, internal ethics usage, and external ethics usage.

Research limitations/implications – It should be noted that the ECE construct has been derived from large companies and organisations in private and public Sweden, which may indicate less applicability to smaller operations. Another limitation may be the validity and reliability across other cultural samples. The dual sample contains a variety of different types of operations, but it may not be transferable to other countries.

Practical implications – The outcome is based on data from private companies and public organisations that indicated they had corporate codes of ethics. Therefore, a suggestion for further research is to examine the ECE construct in other countries/cultures that differ from the ones in this research effort performed in the private and public sectors of Sweden.

Originality/value – The ECE construct introduced makes a contribution to theory and practice in the field as it is based upon a dual sample. It makes a contribution to theory as it outlines a construct for the benefit of other researchers working in both the private and the public sectors. The authors also believe that it may be of managerial interest as it provides a grounded framework of areas to be considered in the implementation of the codes of ethics in both private companies and public organisations.

Lesbian family disclosure: Authenticity and safety within private and public domains

Definitions of family and disclosure of family configuration are important themes for understanding the experiences of contemporary lesbian-parented families. Drawing on multi-generational family interviews with 20 lesbian-parented families in Victoria, Australia, we explore how participants describe and present their families in public contexts. We found a marked difference in experience between lesbian-parented stepfamilies and lesbian-parented de novo families where children are conceived and raised by lesbian parents from birth. Family members adopted a variety of strategies when disclosing parents’ sexual orientation in mainstream social institutions such as health care settings and schools. Some chose a proud, open strategy; while others were more private; yet others chose a passive strategy, particularly when dealing with health care providers, and a selective strategy when dealing with schools. These strategies demonstrate
the fine balance that families must strike between being publicly authentic and creating safety by protecting themselves from negative attitudes.

Codes of ethics in large private sector Australian businesses

This thesis deals with codes of ethics in the top 500 companies operating in the private sector in Australia. We seek to answer two questions. First, can businesses adopt codes of ethics in a meaningful way, or are business ethics a contradiction in terms for profit seeking organisations in competitive markets? Second, to what extent do Australia’s top 500 private sector firms show commitment to codes of ethics? A number of ancillary questions are explored to form a picture of the current Australian situation and to compare it to the rest of the world, especially the US and Canada. Chapter 1 discusses these questions and the origins of the author’s interest in business ethics. This chapter develops a focus upon codes of ethics and their role in assisting to establish and maintain an ethical culture. The chapter looks at previous research on codes of ethics and demonstrates a lack of understanding in Australia on the subject and the need for research into it. Also included in Chapter 1 is the plan for the thesis. Chapters 2 to 4 review the literature upon which the thesis is based. In Chapter 2, the meaning of the terms ethics and business ethics are considered. Deontological and teleological approaches are distinguished and a (largely) teleological model of business ethics is developed. This chapter also asks whether business ethics are possible. The contention that ethics may be good for a business’s profit is explored in-depth and the conclusion is reached that ethics should be pursued for its inherent worth regardless of the economic benefit that can be attributed to it. A number of models of ethical decision making are discussed in Chapter 3 starting with Kohlberg and Kramer (1969). This discussion leads to the conclusion that organisations must create an ethical culture for staff if they require them to embrace ethical practices. If this is a correct conclusion, then the role of senior managers becomes critical in the process. Chapter 4 looks further at the role of senior managers, organisational culture and ethical/unethical behaviour in organisations. The conclusion is that senior managers do play an integral part in shaping the culture of an organisation. Their actions, either overtly or covertly, impact upon their staff and highlight behaviour that the organisation is or is not willing to tolerate. Sims (1991) proposed ten ways to foster an ethical culture and these ideas are set out and further explored through the work of other writers on management ethics. Finally, the link between ethics and strategic planning is examined. In Chapter 5 the methods used for empirical data gathering are described and justified. A number of factors that can lead us to consider a company’s ‘commitment’ to ethics are outlined. A survey of Australian companies was the primary means of data collection. Each question in the survey instrument is listed and explained. Also the survey response rate is reported, as are major demographic characteristics of respondents. Chapter 6 provides the research findings from the survey of the top 500 companies operating in the private sector in Australia. The research examines: i) the current Australian usage and implementation of codes of ethics; ii) the measures put in place in organisations in order to support a code; From this analysis conclusions are drawn about the ‘commitment’ of companies operating in Australia to codes of ethics. Australian companies are becoming aware of the potential of code usage. Companies operating in Australia that have codes appear to be good at implementing codes and examining staff performance in relation to codes. However, they lack the procedures that incorporate education and training and the implementation of the support mechanisms necessary to enhance employee understanding of the code. In Chapter 7, Australian codes are compared to American and Canadian codes for similarity and disparity. The assessment found that in all three countries codes are primarily concerned with company continuance. Australian codes do tend to be more socially oriented than in the other two countries and also less legalistic. Chapter 8 looks at 4 companies from the first survey that were asked for more in-depth information in a quest to determine current best practice in Australia. These organisations were chosen because they appeared, from the first survey instrument, to have put in place mechanisms to assist employees to better understand the code. The implication is that companies must make a conscious, positive effort to ensure that employees are considered in the process of ethical development. They should have input into the process, rather than just being directed to follow another management initiative. The final chapter summarises the research findings and looks at answers to the two major questions and the seven subordinate empirical questions posed at the start of the thesis. The conclusion reached is that companies operating in Australia appear to be moving towards establishing codes of ethics. Those who already have codes display a real commitment to them. The movement appears to be gathering momentum as more organisations see the value of incorporating ethical business practices into the every day workings of their individual companies. Generally, most Australian companies lag behind the rest of the world, but the pace-setting companies are defining their own best practice and achieving positive outcomes for themselves, their employees and other stakeholders.

Allocating risks in public-private partnership projects using a transaction cost economics approach - a case study

Public-private partnership (PPP) projects are often characterised by increased complexity and uncertainty due to their idiosyncrasy in the management and delivery processes such as long-term lifecycle, incomplete contracting, and the multitude of stakeholders. An appropriate risk allocation is particularly crucial to achieving project success. This paper focuses on the risk allocation in PPP projects and argues that the transaction cost economics (TCE) theory can integrate the economics part, which is currently missing, into the risk management research. A TCE-based approach is proposed as a logical framework for allocating risks between public and private sectors in PPP projects. A case study of the Southern Cross Station redevelopment project in Australia is presented to illustrate the approach. The allocation of important risks is put under scrutiny. Lessons learnt are discussed and alternative management approaches drawing on TCE theory are proposed.

Neurofuzzy decision support system for efficient risk allocation in public-private partnership infrastructure projects

The performance of public-private partnership (PPP) infrastructure projects is largely contingent on whether the adopted risk allocation (RA) strategy is efficient. Theoretical frameworks drawing on the transaction cost economics and the resource-based view of organizational capability are able to explain the underlying mechanism but unable to accurately forecast efficient RA strategies. In this paper, a neurofuzzy decision support system (NFDSS) was developed to assist in the RA decision-making process in PPP projects. By combining fuzzy and neural network techniques, a synthesized fuzzy inference system was established and taken as the core component of the NFDSS. Evaluation results show that the NFDSS can forecast efficient RA strategies for PPP infrastructure projects at a highly accurate and effective level. A real PPP infrastructure project is used to demonstrate the NFDSS and its practical significance.
