This chapter provides a taxonomy of key rolling stock types and covers the key engineering principles. This chapter concentrates on the aspects of the rolling stock that make it sustainable in terms of passenger transportation; these aspects are primarily safety and crashworthiness. These are specific items that contribute to make the rolling stock and hence rail system more sustainable; passengers need to be confident that they are travelling in safe rolling stock and the vehicle consist, manufacturing technique or materials used should not compromise the crashworthiness aspects. For this reason, all aspects of this chapter reference vehicle safety and crashworthiness.

Disputes about Canadian exports of softwood lumber to the U.S. have persisted for more than a century. In this paper the roots of the disputes and the prospects for their resolution are examined. The focus is on the following key factors: (1) the nature of supply and demand; (2) the normative differences underlying the systems of timber management in the two countries and differences about what constitutes a “level playing field”; (3) rent seeking by stakeholders; and (4) weakness in bilateral and multilateral trade dispute resolution institutions. The paper concludes that there are good reasons to expect short term solution to the current dispute but persistence of the disputes in the long run.

Purpose – The purpose of the chapter is to sketch the historical and evolutionary development of the Wichita Aircraft Manufacturing Cluster from inception to present and provide a descriptive narrative of aircraft industry knowledge spillovers currently driving effort to establish a Medical Device Manufacturing Cluster. The chapter illustrates how carbon-fiber composite materials knowledge and technology developed for use in the aviation industry is facilitating the creation and growth of medical device manufacturing.

Methodology/approach – We use an historical case study approach to trace the development of the aircraft cluster in the Wichita, KS metropolitan area. A number of technologies are identified that had initially been adopted by one firm but eventually diffused through other firms in the local cluster and ultimately throughout the industry.

Findings – In addition to providing examples of within industry knowledge spillovers, we provide an example of technology-based knowledge that is diffusing through the aircraft manufacturing industry and is now being used as the basis for establishing an unrelated industry manufacturing cluster. The use of carbon-fiber composites in aircraft manufacturing has diffused from one manufacturer to many in the industry. Subsequently, the knowledge base surrounding carbon-fiber composite materials is being used in a local R&D effort to create a second manufacturing cluster producing medical devices ranging from surgical instruments to joint-replacement implants.

Originality/value of paper – The chapter illustrates a unique example of a manufacturing cluster, intra-industry knowledge spillovers, and inter-industry knowledge spillovers to create a new manufacturing cluster.

Perhaps the most difficult objection raised by skeptics of the real options approach concerns the apparent lack of market transactions that would verify that real options have actual value. Although there are no organized exchanges with publicly disclosed prices, there are nevertheless several mechanisms for buying and selling real options. Observing these could offer important advantages in the quest for enhancing the role of real options in financial decision making:•demonstrate that real options can indeed add value•in some cases even gain a sense of the amount of value added by real options•offer expert appraisers methods for improved estimation of the value of a business when real options are part of the organizational capital

The most frequently used method for buying or selling real options occurs when a product that includes real options is sold to customers (often at a premium above the price of a comparable product that does not include real options). Real options that are part of the organizational capital of a business are part of the package in an acquisition (or minority equity position). In this chapter we examine several cases of such transactions.

The premise of this discussion is that private equity players intend to create real options that maximize the value derived from potential movement in the worth of the underlying business platform. This intended maximization occurs when the current value of the exercise instrument equals the current value of the underlying asset (so the option is at the money). It is also clear that when the time horizons of different arrangements tend to be consistent (as tends to happen in private equity arrangements) the attraction will be for higher volatility. The actions often criticized in the media are readily understandable in this context. For example, private equity partnerships are criticized for “borrowing heavily to buy companies, breaking them up, and selling off the pieces at huge profits.” Even before exiting, the private equity players separate the acquisitions into business units and asset pools. This changes an option on a portfolio into a portfolio of options, and we know from option pricing theory that the resulting position is worth more than the starting point.

Private equity partnerships also have been criticized for putting acquisitions into debt to receive dividends. Upon acquisition of a new business platform (perhaps composed of multiple business units) the private equity firm has paid a substantial premium for an option on a portfolio. After separating it into multiple options on different business units, the private equity firm might understandably want to sell assets that do not need to be owned (but could be leased instead), thereby reducing their equity investment and bringing the options closer to the money. Then additional borrowing (and withdrawal of dividends) again brings the options closer to the money.

In order to illustrate the nuances of private equity as real options, we include discussion of three recent cases, each illustrating one of the common paths followed in private equity.

The consideration of alternative sources of material for construction is imperative to reduce the environmental impacts as two-fifths of the carbon footprint of materials is attributed to the construction industry. One alternative material with improved biodegradable attributes which can contribute to carbon offset is bamboo. The commercialisation of bamboo in modern infrastructures has significant potential to address few of the Sustainable Development Goals (SDGs) itemised by the United Nations, namely SDG 9 about industry, innovation and infrastructure. Other SDGs covering sustainable cities and communities, responsible consumption and production and climate action are also indirectly addressed when utilising sustainable construction materials. Being a natural material however, the full commercialisation of materials such as bamboo is constrained by a lack of durability. Besides fracture mechanisms arising from load-induced cracks and thermal modification, the durability of bamboo material is greatly impaired by biotic and abiotic factors, which equally affect its natural rate of degradation, hence fracture behaviour. In first instance, this chapter outlines the various factors leading to the durability limitations in bamboo material due to load-induced cracks and natural degradation based on recent findings in this field from the author's own work and from past literature. Secondly, part of this chapter is devoted to a new approach of processing the surge of information about the varied aspects of bamboo durability by considering the powerful technique of artificial intelligence (AI), specifically the artificial neural network (ANN) for prediction modelling. Further use of AI-enabled technologies could have an impactful outcome on the life cycle assessment of bamboo-based structures to address the growing challenges outlined by the United Nations.

In the 1930s, chlorofluorocarbons (CFCs) were developed as safe, non-reactive alternatives to toxic and explosive refrigerants and propellants such as ammonia, chloromethane, and sulfur dioxide. American engineer Thomas Midgley famously demonstrated these properties by inhaling Freon (CFC-12) and blowing out a candle with it. He was presented with many awards for his discoveries, such as the Perkin, Priestley, and William Gibbs medals. In today's jargon, CFCs might have been called an eco-innovation, because they provided solutions to several environmental issues. However, CFCs solved environmental problems by creating others. In 1974, Sherwood Rowland and Mario Molina published their pathbreaking research that demonstrated CFCs were depleting the ozone layer. In 1989, the Montreal Protocol, which regulates a global phaseout of CFCs, entered into force. A few years later, in 1995, Rowland and Molina received the Nobel Price in Chemistry. The new substitutes for CFCs, hydrofluorocarbons (HFCs), have no known effects on the ozone layer but are extremely potent greenhouse gases (GHGs) and thus subject to the Kyoto Protocol.

To examine the role of new aeronautical technologies in improving commercial aviation’s environmental performance.

Reviews the environmental improvements that may be conferred through the adoption of alternative aviation fuels and new airframe, engine and navigation technologies.

Although aeronautical technologies have evolved considerably since the earliest days of powered flight, the aviation industry is now reaching a point of diminishing returns as growing global consumer demand for air transport outstrips incremental improvements in environmental efficiency. The chapter describes some of the technological interventions that are being pursued to improve aviation’s environmental performance and discusses the extent to which these innovations will help to deliver a more sustainable aviation industry.
