Multi-stakeholders’ assessment of bike sharing service quality based on DEMATEL–VIKOR method

ABSTRACT

Bike sharing is a sustainable mode of urban transportation. Assessing the perceived service quality is essential to improve the development of bike sharing. Most of the existing research evaluates the service quality of bike sharing only from the perspective of its users. This study assesses the perceived quality gap among four different stakeholders including government regulators, platform operators, bike association and users. First, an evaluation criteria system consisting of sixteen criteria obtained from the five dimensions of tangibles, reliability, responsiveness, assurance and empathy is constructed based on a revised service performance model. Thereafter, a hybrid multi-criteria decision-making model that combines Decision-Making Trial and Evaluation Laboratory (DEMATEL) with VIsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is proposed. Then, the model is applied to evaluate the service quality of bike sharing in Xi’an City. Finally, some useful suggestions are given to improve the bike sharing service quality from the perspective of multi-stakeholders.     

Chinese lessons: state-owned enterprises and the regulation of foreign investment in Canada

A recent influx of Asian investment is changing the character of the Canadian oil and gas industry and reviving old debates on the regulation of foreign investment. Particular attention has been placed on investment by state-owned enterprises (SOEs), driven in part by public suspicion about investment from China, which has been the largest source of SOE capital flows to Canada. Recent amendments to the Investment Canada Act have made SOE investment more difficult and have raised questions about the country’s attractiveness as an investment destination. This paper makes the case for non-discrimination of SOEs in the investment review process. In the context of a policy framework that is fundamentally supportive of inward foreign direct investment (FDI), the Canadian government does not require a set of redundant measures to protect against the relatively low risk of undesirable investment.     

Parallel visualization of seismic wave propagation

Today parallel visualization of massive datasets from observation and numerical simulation of seismic waves is one of the major goals of geoscience community. A majority of these datasets are time-varying volume data (TVVD), also known as 4D field data. The difficulty of visualizing them on distributed parallel system mainly lies in the algorithm designing for distributed preprocessing of raw datasets, hierarchical point-to-point or collective communication implementation based on distributed data allocation, synchronous volume rendering techniques. In this work we present viable solutions for preprocessing of raw data sets, novel algorithms of parallel rendering and display matrix. Our main objective is focused on the parallel visualization of results coming from full 4D seismic wave propagation simulations.     

Labour Market Adjustments to Exchange Rate Fluctuations: Evidence from Canadian Manufacturing Industries

This paper provides some of the first empirical evidence on labour market adjustments to exchange rate movements in Canadian manufacturing industries. Controlling for endogeneity using generalized method of moments estimation, it is found that during the 1981–1997 period, exchange movements have a substantial impact on labour input and that this impact has grown over time as the manufacturing industries have become more exposed to trade. In contrast, the exchange rate effect on real wages is estimated to be virtually zero for all manufacturing industries.

Pan-European Advertising: Think Europe—Act Local

Changes in Europe resulting from the unification of EC countries and the accessibility of new Eastern European markets have fundamentally altered the trading environment in which advertising agencies operate. As the advertising industry attempts to get to grips with legislative and media changes, agencies are working hard to create alliances and develop networks which encompass markets in which they did not traditionally have a presence. This article draws on a combination of quantitative and qualitative information collected from secondary sources and extended personal interviews with key agency personnel, advertisers and representatives from the UK's Advertising Association and The Advertising Standards Authority. The objective is to show how the advertising industry and agencies are continuing to gear up to meeting the new demands of the Europeanized market.     

Entrepreneurship,Innovation and Economic Growth: Evidence from GEM data

Studies on the impact of technological innovation on growth have been largely mute on the role ofnew firm formation. Using cross-sectional data on the 37 countries participating in GEM 2002, this paper uses an augmented Cobb–Douglas production to explore firm formation and technological innovation as separate determinants of growth. One area of interest is the contrast between different types of entrepreneurial activities as measured using GEM Total Entrepreneurial Activity (TEA) rates – high growth potential TEA, necessity TEA, opportunity TEA and overall TEA. Of the four types of entrepreneurship, only high growth potential entrepreneurship is found to have a significant impact on economic growth. This finding is consistent with extant findings in the literature that it is fast growing new firms, not new firms in general, that accounted for most of the new job creation by small and medium enterprises in advanced countries.     

Small sample behaviour of some nonparametric multi-sample location tests in the presence of dispersion differences

This paper describes the small and moderate sample behaviour of three studentized non-parametric statistics by Sen and a modified Wilcoxon statistic by Potthoff for testing the equality of location parameters in the presence of dispersion differences. Based on the agreement between the asymptotic and small sample distributions of the statistics as well as a comparison of their power under heteroscedasticity, the studentized Wilcoxon and the studentized Brown and Mood tests arc preferred in the two-sample and c-sample situations, respectively.     

Why managers divest—Evidence from New Zealand's largest companies

Chief Executives from New Zealand's largest companies were surveyed to distinguish divesting and nondivesting companies, and to identify the relative importance of the factors and motives which led to the divestment of 208 business units in the period 1985 through 1990. The divesting companies were considerably larger and faster growing than nondivestors. The typical divestment was motivated by the need to convert unattractive assets into liquid form which could then be held to strengthen the balance sheet, or reinvested in either the core business or new areas.     

Optimal International Taxation and Growth Rate Convergence: Tax Competition vs. Coordination

Optimal international taxation and its implications for convergence in long run income growth rates are analyzed in the context of an endogenously growing world economy with perfect capital mobility. Under tax competition (i) the residence principle will maximize national welfare; (ii) the optimal long run tax rate on capital incomes from various sources will be zero in all countries; and (iii) long term per capita income growth rates will be equalized across countries. Under tax coordination, (i) becomes irrelevant while (ii) and (iii) will continue to hold. In other words, optimal tax policies are growth-equalizing with and without international policy coordination.
