Reforms of the Vietnamese economy have been widely credited for stabilizing the value of the state-issued currency in the marketplace. Nevertheless, how people evaluate the Vietnamese dong as a symbolic form can be read as a symptom of shifting economic and political forces, above all in Ho Chi Minh City, a city associated with commerce. Through three ethnographic cases – the introduction of “big money,” the scarcity of “new money” in 2002, and the campaign to build Automated Teller Machines (ATMs), this paper analyzes the contentious politics around symbolic exchange that shape confidence in Vietnamese currency.

Regression discontinuity (RD) models are commonly used to nonparametrically identify and estimate a local average treatment effect. Dong and Lewbel (2015) show how a derivative of this effect, called treatment effect derivative (TED) can be estimated. We argue here that TED should be employed in most RD applications, as a way to assess the stability and hence external validity of RD estimates. Closely related to TED, we define the complier probability derivative (CPD). Just as TED measures stability of the treatment effect, the CPD measures stability of the complier population in fuzzy designs. TED and CPD are numerically trivial to estimate. We provide relevant Stata code, and apply it to some real datasets.

Strategic option generation is a fundamental step in strategy formulation. Several lenses have been proposed to explain its foundations, including the microeconomics positioning school, and the resource and capabilities based view of the firm. These approaches are largely based on inductive and deductive logics, which are not the logics that provide strategic options that are potentially novel, profitable, and largely differentiated from competitive offerings. In this chapter, we propose a unifying framework of the cognitive foundations of strategic option generation. Building on five fundamental cognitive acts – imitation, framing, analogical reasoning, abductive reasoning, and mental simulation, this proposed model both synthesizes the extant literature and provides guidance about promising avenues for future theoretical and empirical research.

There is a strong body of research that indicates that teacher quality has a stronger effect on student learning than any other school-based factor. At the same time, most teacher evaluation systems have traditionally failed to distinguish among different levels of teacher effectiveness or to link evaluation results to professional development in meaningful ways. In this chapter, we compare teacher responses in S. Korea and the United States to evaluation policies. We provide initial evidence that teachers and principals in Seoul defined “effective teachers” as those who helped manage their schools in areas such as affairs/planning, curriculum/instruction, science and technology, discipline, and extra-curricular activities. In contrast, the Michigan teachers and principals in the study were more likely to view effective teachers as those who planned instruction to meet student needs and provided evidence of student engagement and learning. In addition, educators’ notions of effective teachers seemed related to their responses to new teacher evaluation policies. In particular, the teachers in Seoul strongly resisted the new teacher evaluation policies while their counterparts in Michigan either supported the new evaluation policies or at least did not actively resist them. These differences seemed related to regulative, normative, and cultural-cognitive elements associated with the teacher evaluation policies in the jurisdictions where the teachers and principals worked.

This chapter develops an asymptotic theory for a general transformation model with a time trend, stationary regressors, and unit root nonstationary regressors. This model extends that of Han (1987) to incorporate time trend and nonstationary regressors. When the transformation is specified as an identity function, the model reduces to the conventional cointegrating regression, possibly with a time trend and other stationary regressors, which has been studied in Phillips and Durlauf (1986) and Park and Phillips (1988, 1989). The limiting distributions of the extremum estimator of the transformation parameter and the plug-in estimators of other model parameters are found to critically depend upon the transformation function and the order of the time trend. Simulations demonstrate that the estimators perform well in finite samples.

As noted in this volume’s introduction, Bohemia is considered a core component driving innovation and urban development in the West. From Balzac through Richard Florida, Bohemians are creative. Artists are the quintessence in the sense that breaking the eggs of tradition is a prerequisite to cooking a new omelet. The core idea seems broadly accepted by many readers and commentators in the United States and Western Europe. However, many Korean intellectuals react with puzzlement when asked what or where is the local Bohemia. Many imply that there are none in most Asian countries. There is evidence for this argument. Korean university students seem to dress more elegantly than Westerners. Many female students often wear skirts or dresses and high-heeled shoes and make up to class. Regarding tolerance of homosexuals, there is a famous story about a television star who “came out” with his gay identity and was fired from his job. Dressing inelegantly and tolerating gays are two possible indicators of Bohemia that Richard Florida has stressed, but a critical point to reassess is whether the idea of Bohemia should be revised or whether a new concept should be considered as Asian variations are more specifically incorporated into international theory.

This chapter will examine whether or not Bohemia is absent using scene data. The results will also be compared with those from Chicago to lead to incorporate Asian variations more specifically.

Purpose – Intersections are hazardous locations and to improve their safety we need to understand the factors contributing to crashes at these locations and provide evidence-based recommendations to reduce them. This chapter provides a summary of the findings on infrastructure-related factors contributing to crashes at urban and rural intersections and some discussions on the implications and potential countermeasures.

Approach – A review of the literature on intersection crashes was performed to identify the infrastructure-related crash-contributing factors. Some discussions on the implications and potential countermeasures are then provided.

Findings – The factors contributing to road crashes are diverse and complex. While the safety effects of a few factors (e.g., exposure and speed) are relatively consistent, many factors have different impacts on crash frequency and severity (e.g., types of intersection) and different impacts on urban and rural intersections (e.g., bus stops).

Research Implications – More studies are needed on developing a stronger theoretical or conceptual foundation on the effects of roadway designs and traffic controls on different dimensions of safety (e.g., exposure, frequency, severity, etc.), types of crashes (e.g., head-on, rear-end, etc.) or road users involved (e.g., drivers, pedestrians, cyclists, etc.).

Practical Implications – Transport engineers need to be aware that some treatments may have different effects on different crash types and road users involved. Even though the overall safety may be improved by the treatments designed, they need to consider and mitigate any unintended consequences to satisfy the Pareto improvement principle and the social equity criterion.

Nowadays, the increase in the capacity of batteries has laid the foundations for a broader diffusion of electric mobility. However, electric mobility is causing a growing electricity demand as well as the need to increase the diffusion of suitable charging stations. Within these last challenges, drawing on the recent literature, this chapter provides a critical and wide-ranging review of papers dealing with the formulation of the problem of the localisation of electric vehicle (EV) charging points. This problem is approached considering the electric charging infrastructure technologies, localisation criteria and related methodologies. This review shows how the ‘electric mobility revolution’ applies the technological innovations provided by the energy supply systems, and the location of these systems within the urban contexts. Since the technological innovations have different options, achieving an international standard of charging systems is still far away. Moreover, as there are several criteria, parameters and methodologies, and some analytical approaches for the localisation of electric vehicle charging points, the formulation of the ‘localisation’ problem should require the application of multi-criteria analysis to be addressed. Finally, the results show that there is no consensus on technologies, criteria, and methodologies to be adopted. Therefore, this wide-ranging analysis of the literature would be useful to support possible benchmarking and systematisation accordingly.
