Feasibility of Information-Centric Networking Integration into LTE Mobile Networks

With the current growth of mobile devices usage, mobile net- works struggle to deliver content with an acceptable Quality of Experience. In this paper, we propose the integration of Information Centric Networking into 3GPP Long Term Evolution mobile networks, allowing its inherent caching feature to be explored in close proximity to the end users by deploying components inside the evolved Node B. Apart from the advantages brought by Information-Centric Networking’s content requesting paradigm, its inherent caching features enable lower latencies to access content and reduce traffic at the core network. Results show that the impact on the evolved Node B performance is low and ad- vantages coming from Information-Centric Networking are considerable. Thus, mobile network operators reduce operational costs and users end up with a higher perceived network quality even in peak utilization periods.

A novel monetary incentive for commercial P2P streaming

Today P2P faces two important challenges: design of mechanisms to encourage users’ collaboration in multimedia live streaming services; design of reliable algorithms with QoS provision, to encourage multimedia providers employ the P2P topology in commercial streaming services. We believe that these two challenges are tightly-related and there is much to be done with respect. This paper proposes a novel monetary incentive for P2P multimedia streaming. The incentive model classifies the users in groups according to the perceived video quality. We apply the model to a streaming system’s billing model in order to evaluate its feasibility and visualize its quantitative effect on the users’ motivation and the provider’s profit. We conclude that monetary incentive can boost up users’ cooperation, loyalty and enhance the overall system integrity and performance. Moreover the model defines the constraints for the provider’s cost and profit when the system is leveraged on the cloud. Considering those constraints, a multimedia content provider can adapt the billing model of his streaming service and achieve desirable discount-profit trade-off. This will moreover contribute to better promotion of the service, across the users on the Internet.

The relationship between young people's transit use and their perceptions of equity concepts in transit service provision

This study investigates the effect of price and travel mode fairness and spatial equity in transit provision on the perceived transit service quality, willingness to pay, and habitual frequency of use. Based on the theory of planned behavior, we developed a web-based questionnaire for revealed preferences data collection. The survey was administered among young people in Copenhagen and Lisbon to explore the transit perceptions and use under different economic and transit provision conditions. The survey yielded 499 questionnaires, analyzed by means of structural equation models. Results show that higher perceived fairness relates positively to higher perceived quality of transit service and higher perceived ease of paying for transit use. Higher perceived spatial equity in service provision is associated with higher perceived service quality. Higher perceived service quality relates to higher perceived ease of payment, which links to higher frequency of transit use.

Transit Use by Young People in Times of Financial Austerity: A Cause of Equity Concern?

This study investigates the effect of price and travel time fairness and spatial equity in transit provision on the perceived transit service quality, willingness to pay, and habitual frequency of use. Based on the theory of planned behavior, we developed a web-based questionnaire for revealed preferences data collection. The survey was administered among young people in Copenhagen and Lisbon to explore the transit perceptions and use under different economic and transit provision conditions. The survey yielded 499 questionnaires, analyzed by means of structural equation models. Results show that higher perceived fairness relates positively to higher perceived quality of transit service and higher perceived ease of paying for transit use. Higher perceived spatial equity in service provision is associated with higher perceived service quality. Higher perceived service quality relates to higher perceived ease of payment, which links to higher frequency of transit use.

Modelo multivariante de evolución en el tiempo de la calidad percibida en la educación superior

Las instituciones de educación superior deben gestionar eficaz y eficientemente sus procesos de captación de nuevos estudiantes, y con este objetivo necesitan mejorar su comprensión sobre los antecedentes que inciden en la intención de recomendarlas. Por lo que esta Tesis Doctoral se centra en el estudio y análisis de las componentes de la calidad del servicio de la educación superior, como antecedentes de la intención de recomendación de una institución universitaria. El enfoque que se adopta en esta investigación integra las dimensiones de calidad docente y de calidad de servicio e incorpora en el análisis la valoración global de la carrera. Paralelamente se contempla la moderación de la experiencia y el desempeño académico del estudiante. En esta Tesis Doctoral se hace uso de la Encuesta de Calidad de la Universidad ORT Uruguay cedida a los autores para su explotación con fines de investigación. Los estudiantes cumplimentan la encuesta semestralmente con carácter obligatorio en una plataforma en línea autoadministrada, que permite identificar las valoraciones realizadas por los estudiantes a lo largo de su paso por la universidad. Por lo que la base de datos es un panel no balanceado que consta de 195.058 registros obtenidos, a partir de 7.077 estudiantes en 17 semestres (marzo de 2003 a 2011). La metodología se concreta en los Modelos de Ecuaciones Estructurales, que proporciona una serie de ventajas con respecto a otras aproximaciones. Una de las más importantes es que permite al investigador introducir información a priori y valorar su inclusión, además de reformular las modelizaciones propuestas desde una perspectiva multi-muestra. En esta investigación se estiman los modelos con MPLUS 7. Entre las principales conclusiones de esta Tesis Doctoral cabe señalar que las percepciones de calidad, servicio, docencia y carrera, inciden positivamente en la intención de recomendar la universidad, y que la variable experiencia del estudiante modera dichas relaciones. Los resultados señalan, en general, que a medida que los estudiantes avanzan en su carrera, los efectos totales de la percepción de la calidad del servicio en la calidad global de la carrera y en la intención de recomendar la universidad son mayores que los efectos que tiene la percepción de calidad de la docencia. Estos hallazgos señalan la necesidad que tienen estas instituciones de educación superior de incorporar en su planificación estratégica la segmentación de los estudiantes según su experiencia. ABSTRACT For institutions of higher education to effectively and efficiently manage their processes for attracting new students, they need to understand the influences that activate student intentions to recommend a program and/or college. This Thesis describes research identifying the quality components of a university that serve as antecedents of student intentions to recommend. The research design integrates teaching and service dimensions of higher education, as well as measures of student perceptions of the overall quality of a program. And introduces the student quality and student experience during the program as moderators of these relationships. This Thesis makes use of the Quality Survey of the Universidad ORT Uruguay ceded to the authors for their exploitation for research purposes. The students complete the survey each semester in a self-administered online platform, which allows to identify the assessments conducted by the students throughout its passage by the university. So that the database is an unbalanced panel consisting of 195.058 records obtained from 7.077 students in 17 semesters (march 2003 to 2011). The methodology of analysis incorporated Simultaneous Equation Models, which provides a number of advantages with respect to other approaches. One of the most important is that it allows the researcher to introduce a priori information and assess its inclusion, in addition to reformulate the modellings proposals with a multi-sample approach. In this research the models are estimated with MPLUS 7. Based on the findings, student perceptions of quality, service, teaching and program, impact positively the intent to recommend the university, but the student’s experience during the program moderates these relationships. Overall, the results indicate that as students advance in the program, the full effects of the perception of service quality in the overall quality of the program and in the intention to recommend the university, outweigh the effects of the perceived teaching quality. The results indicate the need for institutions of higher education to incorporate in its strategic planning the segmentation of the students according to their experience during the program.

A consumer-based method for retailer equity measurement: Results of an empirical study

This research extends the consumer-based brand equity measurement approach to the measurement of the equity associated with retailers. This paper also addresses some of the limitations associated with current retailer equity measurement such as a lack of clarity regarding its nature and dimensionality. We conceptualise retailer equity as a four-dimensional construct comprising retailer awareness, retailer associations, perceived retailer quality, and retailer loyalty. The paper reports the result of an empirical study of a convenience sample of 601 shopping mall consumers at an Australian state capital city. Following a confirmatory factor analysis using structural equation modelling to examine the dimensionality of the retailer equity construct, the proposed model is tested for two retailer categories: department stores and speciality stores. Results confirm the hypothesised four-dimensional structure.

Chinese host country nationals' willingness to support expatriates:the role of collectivism, interpersonal affect and Guanxi

The willingness of host country nationals (HCNs) to provide support to the expatriate has received a lot of attention in the literature on international assignments. Surprisingly, though, the number of empirical studies examining this relationship is extremely limited. This study examines the role of HCNs' collectivistic orientation, interpersonal affect, and guanxi in relation to their willingness to support expatriates. Using data from 212 HCNs in China, it is found that HCNs' perceived relationship quality with the expatriate has a significant impact on their willingness to provide assistance, both role information and social support, to expatriates. Further, it is found that relationship quality is related to perceived cultural similarity. The results reinforce the importance of paying attention to the perceptions and reactions of HCNs towards expatriates. Implications of the findings are discussed, and suggestions are offered for future research.

The influence of adaptation and inhibition on the effects of onset asynchrony on auditory grouping

Onset asynchrony is an important cue for auditory scene analysis. For example, a harmonic of a vowel that begins before the other components contributes less to the perceived phonetic quality. This effect was thought primarily to involve high-level grouping processes, because the contribution can be partly restored by accompanying the leading portion of the harmonic (precursor) with a synchronous captor tone an octave higher, and hence too remote to influence adaptation of the auditory-nerve response to that harmonic. However, recent work suggests that this restoration effect arises instead from inhibitory interactions relatively early in central auditory processing. The experiments reported here have reevaluated the role of adaptation in grouping by onset asynchrony and explored further the inhibitory account of the restoration effect. Varying the frequency of the precursor in the range ± 10% relative to the vowel harmonic (Experiment 1), or introducing a silent interval from 0 to 320 ms between the precursor and the vowel (Experiment 2), both produce effects on vowel quality consistent with those predicted from peripheral adaptation or recovery from it. However, there were some listeners for whom even the smallest gap largely eliminated the effect of the precursor. Consistent with the inhibitory account of the restoration effect, a contralateral pure tone whose frequency is close to that of the precursor is highly effective at restoring the contribution of the asynchronous harmonic (Experiment 3). When the frequencies match, lateralization cues arising from binaural fusion of the precursor and contralateral tone may also contribute to this restoration.

The Influence of Servicescape and Local Food Attributes on Pleasure and Revisit Intention in an Upscale-Casual Dining Restaurant

The current study looks at the relationship between servicescape, emotional product involvement, perceived quality of local foods, the positive emotion of pleasure, and revisit intention in an upscale buffet style restaurant on a university campus in the Southeastern U.S. Test results show positive relationships between all of the constructs in the proposed conceptual model. The study also gives practitioners and academics insights into practices that can help to market the use of local foods through the restaurant environment in order to engage emotionally involved customers. This marketing can illicit pleasurable feelings and increase perceived product quality of local foods with the purpose of getting customers to revisit the restaurant. Suggestions for further research on the subject are proposed.

Análisis de las variables de marketing que afectan al valor del cliente. La permanencia como variable controlable

To know how marketing variables affect customer value is essential for a company in order to be market and customer oriented, and to improve investment efficiency in both attracting and retaining customers. Thus, the assessment of the influence of marketing variables in customer value is of prime importance. This is recognized in many empirical studies of these variables, which address the impact of a single variable (or sets of a few variables) on customer value. A comprehensive, integrated assessment of all marketing variables and their interdependencies is an arduous and complex task for researchers and marketing managers. This research proposes a theoretical model of customer value that takes into account all significant marketing variables that have been partially addressed in empirical investigations of other researchers. These marketing variables include brand and reputation, point of sale, employees, price, termination fee commitment, discounts, complementarity of products, experiences, emotions, perceived value, quality, satisfaction, switching costs, and loyalty. The model incorporates the relationship between each variable with retention and with customer value as well as the relationships between them. A special focus is placed on the empirical analysis of the termination fee commitment and its relationship with customer value. This variable is widely used in the telecommunication’s industry for its influence on customer retention from the moment of purchase. However, there is strikingly little research in this topic. A large customer database of a telecommunications company containing five years information about 63.165 customers is used for this purpose. Multivariate linear regression and ANOVA method are applied...
