The modelling and prediction of traffic flow is one of the future challenges for science. We present a simulation tool for an urban road network based on real-time traffic data and a cellular automaton model for traffic flow. This tool has been applied to the inner city of Duisburg. The quality of the reproduced traffic states is investigated with regard to vehicle densities and typical features of urban traffic.

Based on the assumption that the identity and self-understanding of an academic discipline determines how it conceptualizes different domains of social reality, including how it imports and/or exports concepts from or to other disciplines, this chapter presents some of the findings of a major ongoing comparative and cross-disciplinary study of how five key concepts within the combined fields of crisis management and reputation management are applied in three different disciplinary contexts. In this chapter, however, the focus is on just one of these concepts: the concept of reputation.

In Finland the use of public relations (PR) agencies and consultants in political decision making has increased in the last two decades. The development of the Finnish political realm has been similar to that of other Nordic countries where the PR industry has built a strong linkage to the political sphere. The present study analyses how Finnish PR consultants with a political background use and attempt to influence the news media as part of lobbying processes to advance their clients' causes. The chapter is based on 11 interviews with PR consultants that were conducted during November 2018. The main findings indicate that Finnish PR consultants consider the news media and journalists as an important part of lobbying. The media and journalists are considered supportive or alternative forums for advocacy and political debate. PR consultants use the media strategically to establish relationships and networks with journalists, and to advocate long-term political decision making and agendas. Overall, the study indicates that Finnish PR consultants want to be active political interpreters, who together with their clients engage in shaping the political agenda and discourses. This is done by taking advantage of previous political experience and networks, constructing the political agenda for media communication, organising a network of media representatives to influence and finally by framing political messages to the media.

Professional organizations are encouraging accounting educators to better prepare their students for their professional careers by improving students’ interpersonal skills. Although accounting instructors are responding by including group activities in their courses, they may not be considering the negative impact of the phenomenon known as “groupthink” on the outcome of group problem solving. Our search of the Social Science Citation Index (2007) provides evidence that groupthink continues to be an area of research interest in academic disciplines other than accounting. Our search provides no evidence that accounting educators are acknowledging or addressing the potential influences the groupthink dynamic may have on students working in groups. The dynamics involved with groupthink have the potential to affect the quality of decisions made by accounting students in their classroom assignments as well as in their future professional lives. We describe the dynamics leading to groupthink, provide examples from our own experience, and offer accounting educators guidelines to discourage the impact of groupthink on the process of student work groups.

Organizational buying decisions are characterized by conflict which can be studied through the use of coalition theory. It appears, however, that conceptual and methodological problems with coalition theory based on game theory and social psychology have limited its usefulness in helping us understand how such conflict can be managed. This paper proposes the group influence approach to conflict management in organizational buying. The main contribution of this approach is that by treating individuals as representatives of coalitions, sellers and buyers can focus on coalition leaders rather than focus on individuals who, in any case, have to conform to group expectations. Theoretically, the group influence approach recognizes that power and politics are basic forces that affect most spheres of organizational activity. Within such a framework purchase decisions are shown to be politically negotiated settlements between those coalitions involved in making the buying decision.

American multinationals, when deciding pricing strategies for their culturally diverse foreign markets, usually have to debate whether to change or to keep the pricing strategy that they have been using at home. The recent move towards standardization in global markets has only raised the importance of this issue. This research addresses this issue by comparing the effectiveness of 9‐ending prices or just below prices in the USA and in a Central European country, Poland. A conceptual framework was developed to predict why there might be differences in preference for such 9‐ending prices in Poland and the USA. Results from the first study show that 9‐ending prices, which are popular in the US market, are not well received in the Polish market. The second study provided further insights by determining reasons for differences in perception and preference for such prices in the two countries.

Work groups and teams are common across all types of organizations. After providing both practical and scholarly definitions, this chapter examines work team processes common across groups (groupthink and bullying) that largely constrain group work both in and out of meetings. The chapter concludes with attention to work team evaluations (satisfaction with group process and continuity), meeting evaluations, and an overview of relational byproducts of task accomplishment.

The purpose of this chapter is to investigate the nature and range of solutions that can empower and (re-)engage vulnerable and marginalized populations so that they can fully participate in the social, economic, cultural, and political life. These innovative social solutions may be viewed as interactive, generative, and contextualized phenomena that are driven by individuals, organizations and institutional actors at micro, meso, and macro levels.

The use of Middle Range Theory (MRT) as an integrative approach provides an understanding of the processes and mechanisms that govern social phenomena including social innovations. Middle range theorizing focuses on empirical phenomenon and creates general statements that can be verified by data. As such MRT provides an appropriate framework to investigate social innovation trajectory and dynamics.

MRT has been used within the context of SIMPACT, a research project funded under the European Commission’s 7th Framework Program and is the acronym for “Boosting the Impact of Social Innovation in Europe through Economic Underpinnings.” The application of MRT to selected case studies has permitted to identify the micro (individual actions) and macro (structures) links in a variety of social and economic contexts across Europe.

This chapter provides new insights as how different themes studied in the SIMPACT project (i.e., migration, unemployment, education, gender, etc.) in different economic and geographic zones (i.e., Anglo-Saxon, Continental, East-European, and Scandinavia) have been treated by social innovators in response to problems of welfare, economic exclusion, and vulnerability. The research findings are susceptible to be of use in other countries with different economic, political, and social structures.

The significance of vulnerability is well-recognized by social innovators, intermediaries, and impact investors including governments and policy-makers. This requires greater policy and practical interventions, guidelines, and support. However the capacity to intervene is conditioned by financial and human resources. Further investigation about alternative social innovation business models will shed light on the resources and policies that would be needed to foster social innovation.

The analysis of social innovations' economic factors by case studies represents a pioneering effort to highlight social innovation path dependency and building as an effort to overcome the problems of vulnerability and exclusion.

Although the concept of groupthink (the extreme concurrence‐seeking tendency displayed by decision making groups), has been an influential one, empirical research has provided equivocal support for the groupthink model. In this paper, we review previous case and laboratory work on groupthink and identify empirical and theoretical inconsistencies. We then describe a model of groupthink as social identity maintenance (SIM) that is capable of reconciling these inconsistencies and summarize laboratory experiments that specifically test the SIM hypothesis. We use the model to suggest possible pitfalls of previous proposals for preventing groupthink when SIM pressures are operative. Finally, we suggest intervention strategies capable of mitigating groupthink due to SIM that have two objectives: (a) the reduction of pressures toward identity protection and (b) the stimulation of intellectual conflict.
