Challenges faced by world tourism cities – London’s perspective

World tourism cities perform multiple functions and exhibit various characteristics that influence tourism development within their boundaries. They are the main gateway for tourists visiting a country and their success has a direct impact on the visitor economy of that destination. London, the focus of this research, has been one of the world’s top tourism cities for many years, and a key gateway for domestic and international visitors. But despite the important role tourism plays in the economy of the city, there is limited research on the development of this activity in the capital. Using London as an exploratory case study, this paper contributes to better understanding the challenges faced by policy makers when planning and managing tourism in world cities. The adopted research method offers the advantage of gathering insightful information using multiple data collection techniques. Examining this new evidence contributes to expanding the knowledge on the particularities of tourism development in one of the top world cities, which could help policy makers in their efforts to better prepare for potential challenges faced by these complex but important destinations.     

Semitractability of optimal stopping problems via a weighted stochastic mesh algorithm

In this paper, we propose a Weighted Stochastic Mesh (WSM) algorithm for approximating the value of discrete‐ and continuous‐time optimal stopping problems. In this context, we consider tractability of such problems via a useful notion of semitractability and the introduction of a tractability index for a particular numerical solution algorithm. It is shown that in the discrete‐time case the WSM algorithm leads to semitractability of the corresponding optimal stopping problem in the sense that its complexity is bounded in order by with being the dimension of the underlying Markov chain. Furthermore, we study the WSM approach in the context of continuous‐time optimal stopping problems and derive the corresponding complexity bounds. Although we cannot prove semitractability in this case, our bounds turn out to be the tightest ones among the complexity bounds known in the literature. We illustrate our theoretical findings by a numerical example.     

People,Actors, and the Humanizing of Institutional Theory

In much contemporary institutional scholarship, the term ‘actor’ is used as a shorthand for any entity imbued with agency. Talking about actors in institutions thus serves the necessity of allocating agency before returning to the analysis of institutional structures and processes. We find this approach to actorhood limiting, conceptually and normatively. Grounded in the perspective of pragmatist phenomenology, we assert the need for distinguishing between persons and actors, and the value of integrating the person into institutional analysis. We conceive of persons as humans with a reflective capacity and sense of self, who engage with multiple institutions through the performance of institutional roles. People may acquire actorhood by temporarily aligning their self with what is expected from a particular actor-role in an institutional order. Conversely, institutions enter people’s lifeworld as they are personified in people’s social performances. We outline this perspective and examine conceptual and normative implications that arise from the integration of human experience in institutional analysis.     

The impact of the managed care backlash on health care spending

The health spending slowdown associated with the managed care revolution in the 1990s suggests that managed care may have been successful in controlling health care spending. I exploit the passage of state regulation during the “managed care backlash” as well as geographic variation in managed care intensity to measure the impact of managed care on spending. I find that restricting managed care causes a large and significant increase in hospital spending, which cannot be explained by changes in hospital market concentration, other regulatory activity, and multiple other possible explanations. I also do not find effects of the backlash on mortality.     

Communication via a strategic mediator

This paper investigates communication between an informed expert and an uninformed principal via a strategic mediator. We demonstrate that, for any bias in the parties' preferences, there exists a strategic mediator that provides the highest expected payoff to the principal, as if the players had communicated through an optimal non-strategic mediator.     

Freedom and the market

Those who believe that the free market is positively related to both economic efficiency and individual freedom are prone to regard resistance to the establishment of the global market essentially free from any serious sociopolitical constraint as a politically insignificant expression of impatience, ignorance, and hypocrisy. This article attempts to endow the manifestation of discontent with the status quo evident in public protests in Seattle and Washington DC with political significance through explicating it as an expression of a fundamental conflict between economic efficiency and individual freedom inherent in the global implementation of the principle of self-regulating markets. This analysis of the antiglobalization movement is conducted from the perspective of the theoretical foundation of the evaluation of the dynamics of capitalism by Polanyi, Hayek, and Keynes, and its conclusions are brought to bear upon the validity of their contesting views of the relationship between economic efficiency and individual freedom.     

The Role of Cultural and Symbolic Capital in Entrepreneurs' Ability to Meet Expectations about Conformity and Innovation

We conceptualize entrepreneurs' success in acquiring resources as the outcome of a socially embedded process of pursuing legitimacy, which in turn encompasses their ability to meet field incumbents' expectations about conformity and innovation. Drawing from Bourdieu's theory of practice, we specifically discuss entrepreneurs' ability, when entering a business field, to simultaneously conform to existing field arrangements (i.e., to "fit in") and to be perceived as innovators (i.e., to "stand out"). A possible paradoxical relationship marks entrepreneurs' ability to meet both of these expectations; we discuss the role of entrepreneurs' cultural and symbolic capital in this process. In addition, two contingency factors may influence how entrepreneurs' ability to fit in and stand out affects their resource acquisition. First, the contribution of the two facets of legitimacy to resource acquisition is influenced by the maturity of the field the entrepreneur enters. Second, entrepreneurs' resource acquisition may be enhanced by their ability to artfully navigate the possible conflicting demands to fit in versus stand out through impression management.     

Driving forces of chemical risks for the European biodiversity

In the framework of the EU-funded research project ALARM (Assessing LArge-scale environmental Risks with tested Methods), an original method combining the DPSIR (driving forces–pressures–state–impacts–responses) framework and an analysis based on the distinction between the four spheres of sustainability (environmental, economic, social and political) has been developed. This paper presents the application of this method, called “the tetrahedral DPSIR” for the identification and analysis of driving forces of environmental chemicals risks for biodiversity, in Europe. The purpose of this methodology is to help reduce the pressures on biodiversity through modifying the driving forces behind them by offering scientific advice to policy makers. We frame our analysis in the context of the current policy, namely the implementation of REACH (Regulation on the Registration, Evaluation, and Authorization of CHemicals).

On stochastic comparisons of minimum order statistics from the location–scale family of distributions

We consider stochastic comparisons of minimum order statistics from the location–scale family of distributions that contain most of the popular lifetime distributions. Under certain assumptions, we show that the minimum order statistic of one set of random variables dominates that of another set of random variables with respect to different stochastic orders. Furthermore, we illustrate our results using some well-known specific distributions.
