Congestion Tolls

This introductory article to the special issue discusses briefly both the practice and theory of road pricing. Actual methods of charging for road use are discussed, and the current trend towards greater use of time-of-day congestion tolls is noted. The basic model of traffic congestion and road pricing is presented next, and this is followed by a summary of the extensions to the basic model represented in this issue of the Review of Network Economics. Researchers are now developing models that come very close to presenting realistic congestion toll systems that are reasonably efficient.

Critical Reflections

In this introductory article we explore the relationship between statehood and governance, examining in more detail how non-state actors like MNCs, international NGOs, and indigenous authorities, often under conditions of extreme economic scarcity, ethnic diversity, social inequality and violence, take part in the making of rules and the provision of collective goods. Conceptually, we focus on the literature on Areas of Limited Statehood and discuss its usefulness in exploring how business-society relations are governed in the global South, and beyond. Building on insights from this literature, among others, the four articles included in this special issue provide rich illustrations and critical reflections on the multiple, complex and often ambiguous roles of state and non-state actors operating in contemporary Syria, Nigeria, India and Palestine, with implications for conventional understandings of CSR, stakeholders, and related conceptualizations.

The purpose of this special issue is to generate and expand the locations and perspectives from which justice and equity, in multiple forms, are and can be, orienting concepts for critical qualitative inquiry. Although critical inquiry originates from diverse views, concerns, and conditions, all forms would always and already address matters of privilege/harm, equity/ inequity, and justice/injustice, while at the same time challenging power-oriented dualisms, systematic western notions of progress, and capitalist gains. This introductory article describes the work of special issue authors asking questions like: How might critical qualitative inquiry build from the past while at the same time lead to more just possibilities, leading to something we might recognize as inquiry as/toward/for justice? How can critical scholarship be theorized, designed, and practiced with justice as the orienting focus within (en)tangled times, materials and material injustices?

In the last decades, the Italian road transport system has been characterized by severe and consistent traffic congestion and in particular Rome is one of the Italian cities most affected by this problem. In this study, a LevenbergMarquardt (LM) artificial neural network heuristic model was used to predict the traffic flow of non-autonomous vehicles. Traffic datasets were collected using both inductive loop detectors and video cameras as acquisition systems and selecting some parameters including vehicle speed, time of day, traffic volume and number of vehicles. The model showed a training, test and regression value (R2) of 0.99892, 0.99615 and 0.99714 respectively. The results of this research add to the growing body of literature on traffic flow modelling and help urban planners and traffic managers in terms of the traffic control and the provision of convenient travel routes for pedestrians and motorists.

This special issue highlights an exciting range of contemporary, interdisciplinary research into spatial forms, political economic processes, and planning policies that have animated East Asian urbanization. To help situate this research, this introductory article argues that the urban as form, process, and imaginary has often been absent from research on East Asian developmentalism; likewise, the influence of developmentalism on East Asian urbanization has remained under-examined in urban research. To rectify this issue, we propose a concept of urban developmentalism that is useful for highlighting the nature of the urban as a site of and for developmentalist intervention in East Asia. We then outline the contribution made by the articles in this special issue to three key themes that we feel are germane for the study of urban developmentalism across varied contexts: geopolitical economies, spaces of exception, and networks of expertise.

Constructivist Model

This introductory article attempts to set a conceptual stage for the special issue on identities of school leaders. We do this by beginning with a discussion of identity – its definition, philosophical roots, nature, and components. We then move to a discussion of identity development and the various dimensions that characterize this development. The article ends with a brief description of a critical constructivist model of identity. Our intention in the article is not to offer a theoretical framework that will be used by the article authors, but to offer a conceptual stage that provides the background for understanding identity.

Introductory Article

The functioning of the biosphere and the Earth as a whole is being radically disrupted due to human activities, evident in climate change, toxic pollution and mass species extinction. Financialization and exponential growth in production, consumption and population now threaten our planet’s life-support systems. These profound changes have led Earth System scientists to argue we have now entered a new geological epoch – the Anthropocene. In this introductory article to the Special Issue, we first set out the origins of the Anthropocene and some of the key debates around this concept within the physical and social sciences. We then explore five key organizing narratives that inform current economic, technological, political and cultural understandings of the Anthropocene and link these to the contributions in this Special Issue. We argue that the Anthropocene is the crucial issue for organizational scholars to engage with in order to not only understand on-going anthropogenic problems but also help create alternative forms of organizing based on realistic Earth–human relations.

Abstract The influence of usage frequency, and particularly of linguistic similarity on human linguistic behavior and linguistic change in situations of language contact are well documented in contact linguistics literature. However, a theoretical framework capable of unifying the various explanations, which are usually couched in either structuralist, sociolinguistic, or psycholinguistic parlance, is still lacking. In this introductory article we argue that a usage-based approach to language organization and linguistic behavior suits this purpose well and that the study of language contact phenomena will benefit from the adoption of this theoretical perspective. The article sketches an outline of usage-based linguistics, proposes ways to analyze language contact phenomena in this framework, and summarizes the major findings of the individual contributions to the special issue, which not only demonstrate that contact phenomena are usefully studied from the usage-based perspective, but document that taking a usage-based approach reveals new aspects of old phenomena.
