This article evaluates how bus users perceive the quality of their public transport service. In particular it looks at how perception of quality varies according to the available information. The experiment compares an overall evaluation of service quality before and after making passengers reflect on the importance of certain fundamental system variables which they may not have previously considered.Focus groups were used to individualise the most relevant variables. A quality survey was carried out both on-board buses and at bus stops and the overall service quality was related to the aforementioned variables using ordered probit models. The perception of quality is shown to change with the category of user and that there tends to be more criticism towards variations in overall quality until the users are stimulated into thinking more deeply about other influential variables. The application of this methodology may provide operating companies with valuable information for planning marketing policies aimed at different categories of user, in order to improve the service quality and attract more passengers to using public transport. 相似文献

The aim of this paper is to review the usefulness of the software CAQDAS QSR—Nvivo-6 in a PhD. Thesis, which consisted of
finding the long-term psychological effects of experiences of imprisonment and torture for political reasons in their Chilean
survivors. For this research, it was created and administered an in-depth interview to 60 survivors, from which outcome was
9900 paragraphs, coded into 784 categories. The software QSR Nvivo-6 threw a report of frequencies, which were compared quantitatively
using Pearson’s χ
2 square test and cluster analysis. We conclude that the software facilitates the development of qualitative thematic content
analysis, simplifying the coding, analysis and display of data. In Addition, it is very useful when working with large quantities
of information, promoting the reliability and validity of studies. However, other aspects are also required to ensure the
rigor of a qualitative study. 相似文献

Benefits and costs associated to hubbing practices of airlines are still subject to much debate. In the previous literature, some standard spatial concentration indices have been proposed to measure it. However, we show that these indices are “ill-defined” because they do not take into account the salient characteristic of hubbing: connecting passengers. The purpose of this research is to present a new methodology which avoids the pitfalls of other methods. Our new methodology also analyzes the level of concentration of the connecting passengers studying two different dimensions: hub airports and routes. Finally, we apply our methodology to some US carriers. 相似文献

In this paper, we empirically assess the importance of regional and sector-specific determinants of industry dynamics. To
this aim we test three hypotheses (originally proposed by Shapiro and Khemani (1987, Int J Indust Organ 5:15–26)) for the
relationship between the entry and exit of firms: independence, symmetry and simultaneity. Estimates from a panel data system
of equations seem to confirm the simultaneity hypothesis for Spain, i.e. we find evidence of a displacement (replacement)
effect between the gross rate of entry (exit) and the gross rate of exit (entry). Also, our results show that, irrespective
of the hypothesis we use, both sectorial and regional variables affect entry and exit.

The aim of this paper is to analyze the determinants of the strategic environmental behavior of firms and, more specifically,
the external and internal barriers that limit and sometimes even prevent the environmental adaptation. The analysis focuses
on a sample of industrial firms that have at least three workers and that are located in Aragón, a region situated in the
northeast of Spain. In order to achieve this objective, first the theoretical literature on the topic is reviewed. Subsequently,
from the firms which were sampled, the existence of an underlying structure among the totality of barriers is studied. Finally,
this structure is analyzed in order to determine if it has any influence on the degree of proactivity of the firm’s environmental
strategy.

The improvement of data statistics as well as the econometrician methods have facilitated the introduction the new variables
and factors I the economic growth analysis. In this sense, real variables have mainly been considered in the economic growth
studies, but not financial or risk management aspects. In this sense, it is interesting to analyze the relationship between
economic growth and value at risk and the feed-back process. The goal of the paper is to analyze the relationship between
economic growth and risk management and the feed-back process. We will consider economic variables, including economic growth,
rule of law, human capital, fiscal policy and monetary policy, among others, in our analysis. We will analyze the theoretical
relationships between these variables and risk and the effects of risk on economic growth. We will also develop an empirical
analysis considering the case of 15 European Union countries.

We consider a pure exchange economy with a finite set of types of agents which have incomplete and asymmetric information
on the states of nature. Our aim was to describe the equilibrium price formation and analyze how the lack of information may
affect the allocation of resources. To do so, we adapt to an asymmetric information scenario a variant of the Shapley–Shubik
game introduced by Dubey and Geanakoplos (J Math Econ 39:391–400, 2003 ). 相似文献
