Identification of Employment Concentration Areas

This article presents a method to identify “Absolute and Relative Employment Concentration (AREC) areas” for a particular industry. Two novel characteristics of the method are that it simultaneously analyses AREC, and that it combines spatial concentration per area with the spatial concentration in neighbouring areas. The method is easy to understand and apply. It is developed to assist regional policy makers and corporate decision-makers with their investment decisions related to new infrastructure or plants. The identification of concentration areas also allows for analysing the performance of these areas in relation to characteristics such as infrastructure availability and the housing and labour market. This can yield new academic insights that are relevant for regional planners. An application of the newly developed method to five industries in a Dutch province subdivided into 502 areas illustrates the value of the method in comparison to other methods.     

Citizen Participation in Planning: Climbing a Ladder?

Certain levels of public access in the process of the statutory land-use planning have been part of Czech planning legislation since the 1970s, but actual citizen participation has become an issue in practice only during the last decade. Currently citizens have a say but their involvement seldom exceeds mere opposition towards active involvement. Their attempts to be heard in the decision-making process is perceived as a nuisance by developers and some local governments as well. Except for the opponents of specific project proposals, most people feel that involvement in the planning process is futile, having little comprehension of how urban and regional planning may actually influence their lives, their property and their local environment. The paper analyses the effects of the pre-1989 powerlessness on the recent changes in the planning process and it reviews the research and opinions of several scholars in this field. The formal planning process, which deals mostly with land use, is often felt to be too narrowly defined and too restrictive, with limited opportunities for citizen involvement. Strategic planning has been introduced by some municipalities in recent years as a less rigid, more flexible and potentially more participatory approach, but also here the trend that copied the accustomed patterns of statutory land-use planning prevailed in the end. Apart from the 'mainstream' planning, alternative, 'informal' planning has emerged, often supported from abroad and organized by non-governmental organizations (NGOs). Although still marginal, it has introduced active planning by citizens. The absence of legal definition and guidance in the case of non-statutory planning allowed greater diversity in the planning method itself. After several years of this experience, however, it has primarily proven just how diverse the concept of citizen participation might be. On the basis of the analysis of the current diversification of planning methods, an attempt is made to draw some conclusions concerning the evolving process of citizen empowerment and participation in Czech planning, as well as to indicate patterns of the changes of the involvement process in the current stage of transformation.     

Thailand: The Making of a Miracle?

Over the last half century, Thailand has been one of the fastest growing developing countries. This article reviews the causes of that growth. It deals both with the immediate factors, in a growth accounting framework, and with the underlying social and political factors. The author reaches the conclusion that a dynamic entrepreneurial class together with a supportive state were the key elements in Thailand’s rapid and efficient accumulation of production factors. Although in this respect Thailand is similar to a small number of other East Asian countries, the Thai case also has a number of unique characteristics.     

Structural Integrity of Stone Blocks From Charles Bridge in Prague

The Charles Bridge is the oldest, still-standing gothic bridge that crosses the Vltava River in Prague and up to now has belonged among the most sought-after historical monuments in the Czech Republic. The bridge has been repeatedly damaged due to floods and has been repaired several times. In the reconstructions, damaged sandstone blocks were substituted in facing. This experimental study focused on nonlinear ultrasonic spectroscopy for testing stone blocks that were extracted from the historical bridge structure. The objective of these experiments was verifying whether the methods can be applied to evaluating the internal structure of blocks, which are built-in in the structure in situ. Intact-structure blocks, blocks that had been repaired in the past, and damaged-structure blocks were measured. Two methods of nonlinear ultrasonic spectroscopy were applied—the method with single harmonic ultrasonic signal and with two harmonic ultrasonic signals. Measurement results of both applied methods proved resulting parameters correlation with block structure integrity quality.     

Decision-Making on Transport Infrastructure and Contested Information: A Critical Analysis of Three Approaches

Information is highly contested in virtually all decision-making processes on large infrastructure projects, leading to the delay or cancellation of projects. Contested information has two characteristics: uncertainty and ambiguity. The uncertainty of information refers to the lack of reliable knowledge about the characteristics and future effects of infrastructure projects. The ambiguity of information means that different actors have different (legitimate and valid) perspectives on the characteristics and effects of infrastructure projects. Information is contested if both uncertainty and ambiguity apply. In this paper, we develop a theoretical framework based on different perspectives on rationality and the role ascribed to information in decision-making. We then use this framework to analyse three approaches aiming to deal with the contested nature of information. The analysis shows that none of the approaches can fully deal with the contested nature of information, because no practically feasible approach has yet been developed to effectively address the ambiguity of information. We end with a brief discussion of the possible responses to this finding.
