AbstractThis article explores a missing link in the recent literature on the formation of social policies: that between democracy and universalism, one desirable yet elusive feature of these policies. We base our argument on a case study of Costa Rica, the most successful case of universalism in Latin America. We proceed by first depicting Costa Rica's peculiar policy architecture, based on the incremental expansion of benefits funded on payroll taxes. Then we reconstruct the policy process to stress the key role played by technopoliticians in a democratic context. Backed by political leadership and equipped with international ideas, technopoliticians drove social policy design from agenda setting to adoption and implementation. Third, we argue that key aspects of the policy architecture established in the early 1940s were fundamental building blocks for a distinctive and seldom explored road to universalism. We conclude considering contemporary implications.

Key Aspects

In this chapter, the authors pose a theory for the governance of enterprise coherence. The proposed theory consists of three key ingredients: an Enterprise Coherence-governance Assessment (ECA), an Enterprise Coherence Framework (ECF), and an Enterprise Coherence Governance (ECG) approach. The ECA provides an explicit indication of the degree at which an organisation governs its coherence, while also providing a base to achieve a shared understanding of the level of coherence, and actions needed to improve it. The ECF is a practice-based framework that enables enterprises to make the coherence between key aspects, such as business, finance, culture, IT, etc. explicit. The ECG approach offers the instruments to guard/improve the level of coherence in enterprises during transformations. An important trigger to develop this new theory was the observation that many transformation projects fail. These failures even included projects that used an explicit enterprise architecture to steer the transformation. The theory was developed as part of the GEA (General Enterprise Architecting) research programme, involving twenty client organizations. Based on a survey of the possible causes for the project failures, the requirements for the research programme are identified. In developing the theory on enterprise coherence, the following hypothesis is used as a starting point: the overall performance of an enterprise is positively influenced by a strong coherence among the key aspects of the enterprise, including business processes, organizational culture, product portfolio, human resources, information systems, IT support, etc. The research programme uses a combination of design science-based iterations and case study-based research to develop and iterate the theory for enterprise coherence governance. In this chapter, the authors also discuss one of the conducted (real world) case studies, showing the application of the enterprise coherence theory.

Ground Penetrating

We provide a coherent approach for developing an understanding of how and where ground-penetrating radar (GPR) can be deployed for tunnel detection. While tunnels in general are of interest, the more specific focus is tunnels that are hand dug or created with a minimal amount of equipment and resources for clandestine purposes. Determining whether GPR can be used for tunnel detection is impossible without an in-depth knowledge of the operational environment and constraints. To effectively address the question, we define the general characteristics of clandestine tunnels, discuss how to estimate the responses amplitude, define the dominant noise types associated with GPR data, and point out how those factors are affected by the GPR system. The key aspects are illustrated using a controlled field case study.

Key Aspects

Purpose The purpose of the study, upon which this paper is based, was to contribute an improved understanding of the vertical extension of buildings, by presenting a development process for its implementation in which the key aspects to consider when planning such extensions are highlighted. Design/methodology/approach The approach is based on linking the diffusion of innovation together with case study research to stimulate further development in vertically extending buildings. Four cases of vertically extended buildings in Sweden were selected for the study. Findings The development process highlights seven key areas for decisions when planning a vertical extension. These areas are: opportunities for vertical extension; strategies for implementation; detailed planning process; concept development; evaluation; building permit; and procurement. The development processes and lessons learnt from each case are presented, covering both success and failure. Research limitations/implications The research is based on four cases of vertically extended buildings. The findings offer valuable insights into the development process which should provide the research community with an improved understanding of the challenges faced. Practical implications The findings will help planners, housing owners, housing developers and facility managers better understand the conditions that favour successful implementation of vertical extensions. Originality/value The paper provides the reader with an understanding of the challenges faced in the vertical extension of a building and the means of overcoming them to create a simplified development process.

Interaction Management

Recent studies have challenged the assumption that the interpreter is an ‘invisible’ mediator and have demonstrated a departure from the ‘conduit’ role often assigned to interpreters in their professional ethics guidelines (e.g. Russell 2000, Wadensjö 1998, 2004; Yoshida 2007). In this paper, I address the issue of interpreter’s role as an invisible mediator through an examination of interactional ‘repairs’, one of the key aspects of interaction management mechanisms in the tradition of Conversation Analysis. The context of interpreting is Australian Federal Police interviews mediated by Japanese-English interpreters. While some repair sequences in interpreter-mediated police interviews followed common patterns of monolingual police interviews, there were also some features of repairs specific to interpreter-mediated discourse. In particular, due to the interpreting of each turn, in some cases, it is not always possible to ascertain whether it was the primary speaker’s turn or the interpreted version that was the source of ‘trouble’ leading to an interactional repair. The paper demonstrates interpreters’ vulnerability to being identified as the ‘troublemaker’ in repair sequences and consequential face-saving strategies. These strategies included modifying the primary speaker’s utterances or providing explanations for why a need to repair was perceived or why a repair sequence failed to rectify a problem. It is demonstrated that in engaging in these types of problem solving activities, interpreters at times shift roles, sometimes pushing the boundaries of their professional ethics. The paper argues that, while interpreters are often viewed as operating within a third ‘invisible’ space between interlocutors, this invisibility needs to be questioned. It is suggested that the expectation of a completely invisible, or neutral, third space is unrealistic, and that interpreters as cultural and linguistic mediators, and as social beings, continuously negotiate their identity with their clients while interpreting.

Purpose Lanzarote, Spain, as a tourism destination, suffered a rapid tourist expansion for many years, and this has endangered its sustainability. The purpose of this study is to investigate the case of overtourism and its consequences for the local population and the environment, and to identify ways to mitigate this issue. Design/methodology/approach The study uses a case study approach. Data obtained from tourists visiting the destination were used to examine three key aspects of tourism development, namely, the arrival of tourists to the island, the accommodation offer and the growth of the population. Social awareness with environmental values and protection of the island’s natural resources were the main engine to establish measures to mitigate overtourism. Findings The analysis shows rapid growth in the arrival of tourists to the island and how it affected the accommodation offer and the population. It explores the solution that the authorities of the island took to solve the problem of disorganized growth of tourism and makes reference to the importance of managing the image of a destination to contribute to tourism sustainability. Originality/value This research proposes practical solutions to tackle overtourism at a destination which has been used by the United Nations as an example to establish sustainable tourism development guidelines. It proposes a unique mitigation strategy which is derived from the use of natural recreation.
