This study examines the influence of board interlocks and former politicians on decisions regarding acquisitions in Spain. Our research suggests that board interlocks to other firms can positively influence operations in terms of acquisition scale. Our findings also show that this relationship is positively moderated by the presence of former politicians. That is, the effects of interlocks on acquisitions are amplified further when there are former politicians on boards, which confirms their role as community influentials. In the case of Spain, and under-regulated industries, this complementary effect is maintained. However, the role played by interlocks seems to be more important than former politicians, which means that board interlocks can replace other formal methods of acquiring information (through former politicians) while attempting acquisitions.

Abstract This paper explores the role of formal methods as part of the user-centred design of interactive systems. An iterative process is described, developing prototypes incrementally, proving user-centred requirements while at the same time evaluating the prototypes that are executable forms of the developed models using ‘traditional’ techniques for user evaluation. A formal analysis complements user evaluations. This approach enriches user-centred design that typically focuses understanding on context and producing sketch designs. These sketches are often non-functional (e.g. paper) prototypes. They provide a means of exploring candidate design possibilities using techniques such as cooperative evaluation. This paper describes a further step in the process using formal analysis techniques. The use of formal methods provides a systematic approach to checking plausibility and consistency during early design stages, while at the same time enabling the generation of executable prototypes. The technique is illustrated through an example based on a pill dispenser.

Formal methods for thirty years have promised to be the solution for the safety certification headaches of railway software designers. This chapter looks at the current industrial application of formal methods in the railway domain. After a recall of the dawning of formal methods in this domain, recent trends are presented that focus in particular on formal verification by means of model checking engines, with its potential and limitations. The paper ends with a perspective into the next future, in which formal methods will be expected to pervade in more respects the production of railway software and systems.

Purpose This study aims to examine the effects of competing influences emanating from firms’ social structural context (i.e. sent and received board of director interlocks and industry peers) on the adoption of an institutionally contested corporate governance code provision. Design/methodology/approach The corporate governance code provision of interest in this research recommends that German firms listed on German stock exchanges should disclose the individual remuneration arrangements for their board members. This paper uses 945 firm year observations from 2002 to 2006, the time period during which the adoption of this provision was voluntary for firms, to examine the role of firms’ social structural context in the legitimization process of this provision. Findings The results show that sent board interlocks to firms that defy pressures to adopt this practice have an equally pronounced but opposing effect on its institutionalization process. Received interlocks are inconsequential in this process. The results also provide evidence for the existence of competing influences emanating from firms’ industry peers. In contrast to the effects associated with sent board interlocks, at the industry level, peer acquiescence has a more pronounced effect than peer defiance. Furthermore, the practice’s legitimacy among firms’ peers moderates the effects of sent board interlocks. Originality/value The results of this paper suggest that a balanced approach to studying institutional change in corporate governance needs to acknowledge the co-existence of conflicting signals regarding the spread of new institutional models. The findings suggest that firms’ social structural context plays a central role in processes of contested institutional change. Board interlocks and industry peers carry the potential to facilitate institutional change and facilitate institutional continuity and resistance to change. However, not all board interlocks are of equal importance, and industry peers constitute a source of legitimacy to which directors forming the interlocks attend.
