The spanish restaurant sector: evaluating the perceptions of quality

The restaurant sector is one of the fastest growing sectors within the Spanish economy and looks likely to continue its development into the future. The implementation of total quality (TQ) systems in the tourist industry is still a recent phenomenon in Spain. Hence the importance of the client's satisfaction, resulting in the acquisition of an optimum quality level: i.e. cooking is culture and it has to be culturally adapted and promoted. The survey on the customers of Spanish restaurants reported in this article has gathered the perception of quality according to a likert scale from one to five. The objective of the survey was to determine the degree of satisfaction as well as the quality of the establishment, by using a cluster analysis of the data. Amongst the findings of the survey was the importance of the motivation of pleasure that makes people go to restaurants and it is therefore necessary to create a favourable atmosphere of quality the customers will want to come back to. This provides the sector's greatest challenge.     

Linking globalization of entrepreneurship in small organizations

The field of entrepreneurship spans a wide variety of topic areas, and among the most important is that of the small and medium-sized enterprise (SME). The aim of this paper is to link entrepreneurship and SMEs. Attempting to generalize the outcomes of entrepreneurship in small organizations from different sectors, countries or industries should be activities that are part of daily life on an international scale. In extracting and transferring the outcomes of this research into entrepreneurship and SMEs, policy makers should see an aspect that must be consolidated within the environment of international globalization that surrounds us. It should not be forgotten that what starts out as small (i.e. an SME) can become large over time and this entrepreneurship can form a part of a new organizational structure. A brief overview of the contents of each of the articles included in this special issue on the globalization of entrepreneurship in small organizations is also presented herein.      

Management factors affecting the performance of technology firms

This paper analyzes high-technology firms within the European Union to determine the factors that influence performance through business productivity. The study examines six different factors that are representative of entrepreneurial activity, firstly from a purely business standpoint, and subsequently from the areas of production and technology, human resources, strategy and marketing and, lastly, the economic-financial area. Results indicate a direct relation between productivity and factors such as private borrowing, dynamism or using price as a strategic factor, while the reverse is true for concepts such as family resources, level of investment in R&D or training programs.     

The α-stable processes and their relationship with the exponent of self-similarity: Exchange rates of USA Dollar,Canadian Dollar,Euro and Yen

This research work analyzes the yields of the exchange rate parities of the American dollar, Canadian dollar, Euro, and Yen; estimates the basic statistics and the α-stables; carries out the Kolmogorov–Smirnov, Anderson–Darling, and Lilliefors goodness of fit tests; estimates the self-similar exponents and carries out the t and F tests, ruling out that the series of parities are multifractal. It also estimates the confidence intervals of the exchange rate parities and concludes that the estimated α-stable distributions are more efficient than the Gaussian distribution to quantify the risks of the market, and that the series are self-similar. Through the ? index, we can infer the risk of the events, indicating that the parities are anti-persistent and thus have short-term memory, mean reversion, and a negative correlation with the high risk in the short and medium term. The estimation and validation of the α-stable distributions and the self-similar exponent are important in the evaluation and creation of innovative investment instruments through financial engineering, risk administration, and the evaluation of derived products.
