Initially, abibliographic review was made about services, service quality and SERVQUAL scale. The proposed model is an adaptation of the SERVQUAL scale to the Call Centers. Evaluating the results, it is possible to identify that the major part of the interviewers perceive the dimensions related to reliability and attendance. In the oth... Heriney Lima Queiroga http://biblioteca.universia.net/ficha.do?id=44844597 This research has focused on the customer evaluation of perceived quality in the urgent transport service in Spain. Using different statistical procedures, such as ordinal regression, between-groups comparison or multilevel modeling, this study shows how the perceived service quality of the public company «Correos» is lower than several of the main competitors: Seur, MRW and Nacex. Despite the investment achieved by this public institution in order to improve service quality, these efforts ha... Martínez García, José Antonio; Martínez Caro, Laura http://biblioteca.universia.net/ficha.do?id=47185932 ABSTRACT. This paper presents an assessment method for fast and quantified estimation of the Perceived Quality of Service (PQoS) for homogeneous MPEG-4 video content, enabling optimized utilization of the corresponding storage and bandwidth resources. Besides, the Mean Perceived Quality of Service (MPQoS) as a function of the video encoding rate is introduced and exploited as a metric for objective video quality assessment. The validity of this metric is evaluated by comparing PQoS experiment... H. Koumaras; E. Pallis; G. Xilouris; A. Kourtis; D. Martakos; J. Lauterjung http://biblioteca.universia.net/ficha.do?id=41817807 Traditional visual quality metrics measure fidelity instead of quality, even though fidelity, i.e. the accuracy of the reproduction of the original on the display, is just one of the many factors determining the overall perceived quality. In this paper, the addition of image appeal attributes is investigated in order to bridge this gap. Sharpness and colorfulness are identified among these attributes and are quantified by means of an isotropic local contrast measure and the distribution of ch...

Stefan Winkler http://biblioteca.universia.net/ficha.do?id=41960386 This paper, which summarises work on measuring users' opinions of the quality of software products carried out the last four years, presents the experience gained from measuring users' perception of software quality. Although this paper briefly presents the survey method and the techniques used to ensure the quality of the responses, it mainly emphasises the problems related to such measurements and the human factors that the measuring team has to overcome. It also presents examples from the ... Michalis Xenos http://biblioteca.universia.net/ficha.do?id=41961872 This paper presents a method for measuring customer's perception of software quality. We argue that, although the importance of the perceived product quality is recognised world-wide, there does not exist a rigorous method for measuring customer perception of product quality. This paper presents a method expanded to measure not only end- -- -users perception for the product, but also company employees perception for the quality of the internal deliverables produced within the company M Xenos,D Christodoulakis http://biblioteca.universia.net/ficha.do?id=42115613 As the number of Web users and the diversity of Web applications continues to explode, Web Quality of Service (QoS) is an increasingly critical issue in the domain of e-Commerce [re]. This paper presents experiments designed to estimate users' tolerance of QoS in the context of e-commerce. In addition to objective measures we discuss contextual factors that influence these thresholds and show how users' conceptual models of Web tasks affect their expectations. We then show how user thresholds... Allan Kuchinsky,Service User http://biblioteca.universia.net/ficha.do?id=41640996 There is currently much discussion of Quality of Service (QoS) measurements at the network level of real-time multimedia services, but it is the subjective quality perceived by the user that will determine whether these applications are adopted. This paper argues that ITU-recommended methods for subjective quality assessment of speech and video are not suitable for assessing the quality of many newer services and applications. We present an outline of what we believe to be a more suitable tes... Anna Watson,M.
