The purpose of this paper is to investigate issues relevant to service quality and propose a conceptual model addressing the convictions held by consumers in relation to the service quality of sport services as regards spectators and their influence on sport consumption.

A quantitative method was used for the purpose of this study and 1,643 questionnaires were gathered and analyzed. The current research intended to employ an integrated service quality model within the scope of sport spectating. The model included five fundamental factors and they were examined in association with the behavioral intentions that spectators have. By combining all these factors and aspects, it was attempted to shape consumers’ general perception regarding quality in service. The model of the research considers quality in service to be a hierarchical construct comprising many dimensions and it is observed that service quality can be classified into five factors, all of which can be defined by a variety of corresponding sub-factors.

The outcomes showed that four of the suggested factors regarding quality (i.e. game quality, augmented service quality, interaction quality and outcome quality) had an important as well as favorable influence on sport consumption.

The empirical evidence for this research is derived from one specific professional sport event (European Basketball League) and spectators who took part were from Greece. Future research could use a wider sample of sport events and the participation of spectators from various countries is necessary before such findings are generalized.

The present research provides a contemporary analysis of factors influencing sport spectators anticipated quality and their influence on sport consumption.

The purpose of this paper is to present a method for early crack detection in rotating shafts. A rotor-bearing system, consisting of an elastic rotor mounted on fluid film bearings, is used to detect the presence of the crack at a depth of around 5 percent of shaft radius. The fluid film bearings, the shaft and the crack introduce coupled bending vibrations both in the horizontal and vertical plane. Experimental time series of the rotor composite response under normal steady-state operation are uncoupled, to develop a signal processing procedure able to reveal the presence of the crack.

The variation of the coupling property that a crack (breathing or not) or a cut (always open) introduces into the system and the localization of the coupling in the time domain is a concept proposed as a means to detect transverse surface cracks in rotating shafts. This consideration is combined with the concept of external excitation for the development of an additional crack-sensitive response during system normal operation. Using an external excitation of an active magnetic bearing of specific duration, frequency and amplitude, the method uses this coupling variation during rotation.

The method is simple, quick and effective for early crack detection, being able to detect cracks as shallow as 5 percent of the shaft radius while the system is under normal operation, and can even be applied real-time. Experimental verification uses a simple elastic rotor with a cut mounted on fluid film bearings, with the cut producing similar coupling phenomena as an opened crack. Experimental results are encouraging.

The method used is simple, quick and effective for early crack detection, being able to detect cracks as shallow as 5 percent of the shaft radius while the system is under normal operation, and can even be applied real-time.

This paper attempts to examine the relationship between service quality and customer satisfaction in spectator sports. The relationship between these two constructs is examined, first, by a review of the literature to date and, second, by the results of almost 200 questionnaires completed by spectators at two professional basketball games in Athens, Greece. The results of the questionnaire study are examined and, in conclusion, the implications and limitations of the study are discussed. Areas for further research are also suggested.

The present study attempts to offer more insights into the Greek organic market. It examines the organic products as “eco‐products”, suitable for “green” consumers, who are ecologically/environmentally ecology‐aware and who are concerned with health and quality‐of‐life issues. Analysing a countrywide sample, the survey concludes that three consumer types exist in terms of attitude towards, purchase intention and awareness of organic products: the “unaware”, the “aware non‐buyers”, and the “(aware) buyers” (or simply buyers) of organic food products. After developing a detailed profile of the first two, the “aware buyers” type is segmented in terms of five groups of personality and behavioural factors, defined in the international literature as the driving forces of organic purchasing.
