The purpose of this study is to discuss prevalent socio-psychological models which examine how tourists’ needs and motivations affect their destination choices by collectively considering Plog’s (1974) psychographic profiles, Cohen’s (1979) tourist typology and Peace’s (1988) travel career ladder. The current study argues that no single model can adequately explain tourists’ destination selection process as well as travel behaviors and introduces a new integrated perspective of existing psychological models.

Examining responses from 202 Hong Kong residents who have travel experience, this study divides the respondents’ psychographics into three types.

Using multinomial logit model (MNL) analysis, the study finds that tourists’ travel motivations and destination settings can be varied by their psychographics types. The findings also reveal that tourist’s psychographic types can be varied by demographics, travel type, frequencies, duration, purpose and destination setting.

The study provides implications for tourism marketers as well as the tourism literature by suggesting an integrative approach for a better understanding of tourist motivations.

Urban water bodies play an important role in reducing summertime urban heat island (UHI) effects. Previous studies focused mainly on the impact of water bodies of large areas, and there is no analysis of the efficacy and scale effect of how small and medium-sized water bodies reduce the UHI effects. Hence, these studies could not provide theoretical support for the scientific planning and design of urban water bodies. This study aims to confirm, within different scale ranges, the efficacy of a water body in reducing the summertime UHI effects. We propose a scale sensitivity method to investigate the temporal and spatial relationship between urban water bodies and UHI. Based on the scale theory and geostatistical analysis method in landscape ecology, this study used the platforms of 3S, MATLAB, and SPSS to analyze the distance-decay law of water bodies in reducing summertime UHI effects, as well as the scale response at different water surface ratios. The results show that the influence of water surfaces on UHIs gradually decreases with increasing distance, and the temperature rises by 0.78 °C for every 100 m away from the water body. During daytime, there is a scaled sensitivity of how much water surfaces reduce the summertime UHI effects. The most sensitive radius from the water was found at the core water surface ratio of 200 m. A reduction of UHI intensity by 2.3 °C was observed for every 10% increase of the average core water surface ratio. This study provides a theoretical reference to the control of heat islands for the planning and design of urban water bodies.

The purpose of this paper is to assess the blast‐mitigation potential and the protection ability of an air‐vacated buffer placed in front of a target structure under realistic combat‐theatre conditions.

The blast‐mitigation efficacy of the air‐vacated buffer concept is investigated computationally using a combined Eulerian‐Lagrangian (CEL) fluid‐structure interaction (FSI) finite‐element analysis.

The two main findings resulting from the present work are: the air‐vacated buffer concept yields significant blast‐mitigation effects; and the buffer geometry and vacated‐air material‐state parameters (e.g. pressure, mass density, etc.) may significantly affect the extent of the blast‐mitigation effect.

The main contribution of the present work is a demonstration of the critical importance of timely deployment of the buffer relative to the arrival of the incident wave in order to fully exploit the air‐vacated buffer concept.

This study aims to examine the impact of relative importance of local characteristics, distance from the city centre and unobservable spatial relation in explaining values of constant‐quality apartment units in Vienna.

Drawing on recent developments in spatial econometrics and spatial hedonic house price modelling, the rent gradient hypothesis is examined by means of hedonic regression and spatial hedonic regression. Spatial autocorrelation tests are applied in order to assess possible presence of spatial dependence. The authors borrow Florax et al.'s specification search strategy in order to choose the most appropriate spatial model specification.

This research shows that local characteristics – or particularities – proxied by district and distance from the city centre are important location variables with regard to the Viennese apartment market. The spatial analysis suggests that the apartment prices are spatially autocorrelated and the Viennese apartment market has a distance‐based neighbourhood structure. The main finding is, however, that residents are willing to bid more for constant‐quality apartment units that are close to the centre of the city.

Rent gradient hypothesis is usually tested within non‐spatial hedonic frameworks: this study estimates a spatial hedonic model additionally in order to allow for comparison of results. This is also the first article to apply recent developments in spatial econometrics to examine explicitly rent gradient theory in the context of the Viennese apartment market.

Considers the scope for applying expert system techniques to assist in decisions regarding site location. Begins with a review of the theoretical literature and assesses the progress made in developing computer models. Its central theme is that the next step forward in this area is to develop expert systems. Addresses the question of the design of an expert system which would improve the decision‐making process. Concludes that such a system is well within the scope of current technology, as long as developers can avoid being overambitious and as long as the end result is highly user friendly.

The aim of this research is to explore the relationship between destination supply-side factors, visitor demand-side factors and the role of local government authorities in supporting the drive tourism market with effective interventions. A mixed methods approach was used to gather qualitative data from 14 destination stakeholders, which informed the development of a survey of 397 drive tourists to the Atherton Tablelands, in the far north of Australia. The findings identified stakeholder concerns about fragmented regional promotions by different regional entities, weakened destination branding and infrastructure needs. Drive tourist surveys indicated that although the destination provides a competitive tourism experience, there were concerns about the availability of information. This research highlights the danger of destination disunity, and the theoretical and practical contributions of the learning destination concept to understanding the importance of destination-wide, stakeholder collaboration, although it may be difficult to implement.

Recreational needs, their resulting demands and ensuing supply systems have become an increasingly difficult matter for society to manage and to establish consistent policies for. The difficulty seems to arise out of the two basic elements that constitute the recreational mosaic: first we have the difficulty in establishing what constitutes recreational needs for large populations and what are the characteristics and levels of recreational demand for various activities; secondly, even if one can arrive at reasonably accurate measurements of recreational demand levels, it is exceedingly difficult to construct a set of mechanisms, which in a coordinated way can monitor the supply, and the same time can do this according to principles consistent with good land management.

Multinational corporations (MNCs) have increasingly sourced knowledge across borders, and foreign subsidiaries operations have played a critical role in MNC international knowledge sourcing strategies. The growing responsibility of foreign subsidiaries has paralleled an interest on the geography of this phenomenon by international business and international management scholars. In this chapter, we review this research. In addition, based on recent research in economics and management drawing on economic geography and innovation studies, we highlight possible avenues of research to enrich our understanding of the geographical aspects of international knowledge sourcing. In particular, we suggest three lines of research opportunities. A first opportunity relates to the explicit consideration of distance and border effects. A further research opportunity arises from investigating the geographical distance of heterogeneous host country knowledge sources from the foreign subsidiary. A final research opportunity we discuss is about the contribution of heterogeneous host country knowledge sources to the variety of knowledge developed by the foreign subsidiary.

To provide an eddy‐viscosity turbulence model that accounts for the non‐equilibrium shape of the energy spectrum and for the effect of velocity correlation on turbulent viscosity.

The turbulence model is built using the standard kε model as the starting point. It is suggested that the character of turbulence depends on the time elapsed since its generation. Therefore, a local variable named “age of turbulence” or α, is defined and its transport equation is derived. Two hypotheses are formulated. The first one is that the shape of the energy spectrum depends on α. The second one is that also the effect of velocity correlation on turbulent viscosity is a function of α, in analogy with the dispersion coefficient of a particle in a turbulent flow. Hence, expressions for the characteristic time scaleτ_T and the turbulent viscosity ν_T are proposed and they are integrated in the standard kε model, resulting in a three equation model named here kεα. The expressions of ν_T and τ_T reduce to those of the kε model in decaying turbulence, and deviate from them in recently produced turbulence. The empirical constants are calibrated and various benchmark experiments are simulated.

A comparison between computed results and experimental data show that the kεα model is generally more accurate than the standard kε model.

The “age of turbulence” has not been used previously to characterise turbulence. The work is especially relevant for combustion/reacting applications, where the expression of the characteristic turbulence time scale is crucial for the estimation of the reactant mixing rates.

Finite element (FE) models are considered for the penetration of magnetic flux in type-II superconductor films. A shell transformation allows boundary conditions to be applied at infinity with no truncation approximation. This paper aims to determine the accuracy and efficiency of shell transformation techniques in such non-linear eddy current problems.

A three-dimensional H – ϕ formulation is considered, where the reaction field is calculated in the presence of a uniform applied field. The shell transformation is used in the far-field region, and the uniform applied field is introduced through surface terms, so as to avoid infinite energy terms. The resulting field distributions are compared against known solutions for different geometries (thin disks and thin strips in the critical state, square thin films). The influence of the shape, size and mesh quality of the far-field regions are discussed.

The formulation is shown to provide accurate results for a number of film geometries and shell transformation shapes. The size of the far-field region has to be chosen in such a way to properly capture the asymptotic decay of the fields, and a practical procedure to determine this size is provided.

The importance of the size of the far-field region in a shell transformation and its proximity to the conducting domains are both highlighted. This paper also provides a numerical way to apply a constant magnetic field in a given region, while the source, on which only the far-field behaviour of the applied field depends, is excluded from the model.
