This chapter outlines complex and conflicting issues related to designing tall buildings. It gathers a vast amount of fragmented criticism and concerns and organizes them around the three pillars of sustainability: social, economic, and environmental. Mapping out the “unsustainable” aspects forms the foundation for addressing them in future research and tall building developments. The chapter engages the reader with a preliminary discussion on potential solutions to the outlined problems. It also balances extensive criticism by highlighting the virtues and advantages of tall buildings. Consequently, this chapter forms a foundation for improving the sustainability of tall buildings whenever and wherever they are constructed.

Purpose – The purpose of this chapter is to advance understanding of regional industry or innovation clusters and the opportunities that the cluster framework provides policymakers for delivering economic impact, clarifying economic priorities, and coordinating disparate programmatic efforts, and to articulate some basic principles for formulating cluster strategies.

Methodology/approach – As the cluster concept enters its third decade and the body of related literature reaches a new level of maturity a consensus has emerged among academics and policy thinkers on the economic benefits of clusters. In fact, clusters have emerged as major focus of economic and policy discussion just now – in what the authors dub a “cluster moment” – by dint of their demonstrated practical impact, their value in paradigm discussions, and their potential utility in policy reform. The chapter reviews the benefits of clusters and traces their ascendance – and re-emergence post-recession – among policy thinkers.

Findings – New research confirms that strong clusters tend to deliver positive benefits to workers, firms, and regions. As a paradigm, they reflect the nature of the real economy and as a matter of policymaking, clusters provide a framework for rethinking and refocusing economic policy. In pursuing cluster-based economic development strategies, policy leaders should not try to create clusters; use data to target interventions, drive design, and track performance; focus initiatives on addressing discrete gaps in performance or binding constraints on cluster growth; maximize impact by leveraging pre-existing cluster-relevant programs; align efforts vertically as well as horizontally; and let the private sector lead. All three tiers of the nation's federalist system have distinct and complementary roles to play in advancing the cluster paradigm.

Research limitations/implications (if applicable) – The paper includes no new/original data.

Practical implications (if applicable) – Given that clusters have emerged as a major focus of economics and policy, this chapter lays out a core set of general principles for pursuing cluster-based economic development strategies – and for avoiding common pitfalls – to which policymakers can adhere.

Originality/value of paper – The chapter advances cluster thinking and cluster strategies as a paradigm with the potential to accelerate regional economic growth and assist with the nation's needed restructuring and rebalancing toward a more productive post-recession economy.

The vehicle–track interaction and the resulting dynamic response of the vehicle involve a number of complex nonlinear problems. Large vertical loads act through a small contact patch leading to very high contact pressures. Transverse loads acting through this contact induce a relative velocity between wheel and rail expressed in non-dimensional form as a creepage. The wheel and rail profiles determine the contact patch shape and affect the ability of the vehicle to run stably. If the yaw stiffness of the axles is too low, the vehicle will become unstable at a relatively low speed; conversely, if the yaw stiffness is too high, the curving behaviour will be adversely affected. The vehicle suspension, especially the secondary suspension, also affects the ride comfort of passengers. Finally, it is shown how the speed profiles of accelerating and decelerating trains can be calculated from basic assumptions about the train power, adhesion and rolling resistance.

Purpose – This chapter examines the factors that influence the ability of anti-gentrification movements to get media coverage for their core policy goals. It takes, as a point of departure, the suggestion that the media supports the growth machine and is not inclined to provide favorable coverage to movements trying to limit development.

Design/methodology/approach – In comparing six newspapers’ coverage of anti-gentrification movements in San Francisco's Mission District and West Oakland, we suggest a more nuanced theoretical understanding of media coverage of urban movements against development. The analysis of newspaper articles published in six Bay Area newspapers from 1995 to 2005 illustrates tremendous variations in favorability of coverage between the two movements.

Findings – There are also large variations in the extent to which movements’ core policy goals are represented in newspaper articles. Although the Mission District received more coverage than the West Oakland movement, the West Oakland movement was better able in getting its core policy goals into its coverage than the Mission District movement. The West Oakland movement was more effective in generating media attention for its core policy goals through its organized public protests than the Mission District movement.

Originality/value – This chapter adds to the genre of research analyzing newspaper coverage of social movements. It demonstrates that the coverage is more nuanced than previously reported. Factors such as phase in the movement and the framing of the issues are related to whether the media covers the story in a negative or positive manner.

It shows that NYC, LA and some other urban locations rank very high nationally, and above many suburban and smaller population counties, even in bike events (for mountain and road bikes).

This paper deals with the organizing of interactive product development. Developing products in interaction between firms may provide benefits in terms of specialization, increased innovation, and possibilities to perform development activities in parallel. However, the differentiation of product development among a number of firms also implies that various dependencies need to be dealt with across firm boundaries. How dependencies may be dealt with across firms is related to how product development is organized. The purpose of the paper is to explore dependencies and how interactive product development may be organized with regard to these dependencies.

The analytical framework is based on the industrial network approach, and deals with the development of products in terms of adaptation and combination of heterogeneous resources. There are dependencies between resources, that is, they are embedded, implying that no resource can be developed in isolation. The characteristics of and dependencies related to four main categories of resources (products, production facilities, business units and business relationships) provide a basis for analyzing the organizing of interactive product development.

Three in-depth case studies are used to explore the organizing of interactive product development with regard to dependencies. The first two cases are based on the development of the electrical system and the seats for Volvo’s large car platform (P2), performed in interaction with Delphi and Lear respectively. The third case is based on the interaction between Scania and Dayco/DFC Tech for the development of various pipes and hoses for a new truck model.

The analysis is focused on what different dependencies the firms considered and dealt with, and how product development was organized with regard to these dependencies. It is concluded that there is a complex and dynamic pattern of dependencies that reaches far beyond the developed product as well as beyond individual business units. To deal with these dependencies, development may be organized in teams where several business units are represented. This enables interaction between different business units’ resource collections, which is important for resource adaptation as well as for innovation. The delimiting and relating functions of the team boundary are elaborated upon and it is argued that also teams may be regarded as actors. It is also concluded that a modular product structure may entail a modular organization with regard to the teams, though, interaction between business units and teams is needed. A strong connection between the technical structure and the organizational structure is identified and it is concluded that policies regarding the technical structure (e.g. concerning “carry-over”) cannot be separated from the management of the organizational structure (e.g. the supplier structure). The organizing of product development is in itself a complex and dynamic task that needs to be subject to interaction between business units.
