It is common practice for service providers, such as cell phone network providers, to utilise relationship marketing strategies in an effort to retain their customers and thereby to increase profitability. Customers with relationship intentions are willing to respond to such efforts while other customers will refrain. Service failures negatively impact relationship marketing efforts and thus complicate service providers’ relationship-building efforts. Therefore, service providers endeavour to restore customers’ post-recovery satisfaction and loyalty through service recovery efforts to retain their customers. However, the influence that customers’ relationship intentions have on this process has not been considered. Previous research on relationship intention in South Africa focussed only on developing a valid and reliable relationship intention measurement scale. For this reason, the primary objective of this study was to determine the influence of relationship intention on customer satisfaction, loyalty and retention following service recovery within the cellular industry. Supporting the primary objective, a model depicting the influence of respondents’ relationships intentions on satisfaction, loyalty and retention following service recovery was developed. Furthermore, a model depicting the interrelationships of the relationship constructive dimensions of the service recovery process uncovered during this study was also developed. Through non-probability convenience sampling of adults 18 years and older (residing in Johannesburg and the surrounding residential suburbs) who have used a cell phone network provider for three years or longer, 605 respondents completed interviewer-administered questionnaires. Demographic and patronage information, together with respondents’ relationship intentions, attitudes towards complaining, customers’ complaint behaviour, expectations of service recovery, perceived service recovery as well as satisfaction, loyalty and retention following service recovery, were obtained. Results indicated that no associations exist between respondents’ levels of relationship intention and their relationship lengths, as well as whether they had contractual agreements with their cell phone network providers. It is therefore recommended that instead of using relationship length or contractual agreements, cell phone network providers should use customers’ relationship intentions to identify customers for relationship marketing purposes. Findings from this study furthermore include that respondents’ relationship intentions influence their propensities to complain, as well as the likelihood that they will voice a complaint regarding dissatisfactory service delivery. It is therefore recommended that cell phone network providers use the opportunity to identify customers with relationship intentions through customers’ complaint behaviour. This study found that respondents’ relationship intentions influence both their expectations of cell phone network providers to take service recovery action, as well as their perceptions of service recovery. Respondents’ relationship intentions also positively influence their satisfaction, loyalty and retention following service recovery. Based on these findings, it is recommended that cell phone network providers should always take corrective action following service failures (such as billing errors in this study), preferably by including at least an acknowledgement, apology, explanation and rectification of the problem as part of the service recovery efforts. Such a combination of service recovery efforts will increase the satisfaction, loyalty and retention of customers with higher relationship intentions. From the results it can be concluded that customers’ relationship intentions influence their behaviour with regard to propensity to complain, voicing, expectations of service recovery action, perceptions of service recovery, as well as satisfaction, loyalty and retention following service recovery, when service failures occur. The proposed model developed from these findings results in the recommendation that cell phone network providers should view the service recovery process as an interrelated process influenced by customers’ relationship intentions. Cell phone network providers should note that customers with higher relationship intentions will attempt to salvage the relationship when service failures occur, which contributes to their satisfaction, loyalty and retention following service recovery. This study contributes to establishing relationship intention theory by confirming the positive influence of customers’ relationship intentions on constructive behaviour when service failures occur. Moreover, practical recommendations concerning cell phone network providers’ response to billing errors are proposed. Future research should address the methodological limitations of this study by using probability sampling, and data should be collected from all South African provinces. Real-time service failures should be considered as opposed to the scenario-based approach used in this study. Important influences on customer behaviour when service failures occur, such as the perceived severity of service failure, service failure type, perceived justice and attributions, should also be considered with regard to their influence on the constructs of this study. Lastly, the antecedents of or differences with regard to customers’ relationship intentions based on personality, generational cohort or population group deserve further attention to establish relationship intention as study field within the domain of relationship marketing. / PhD (Marketing Management), North-West University, Potchefstroom Campus, 2014.

O trabalho justificou-se pela necessidade de uma análise conjunta dos três temas, como forma de viabilizar uma melhor compreensão destes temas como elementos relevantes do paradigma de marketing de relacionamento. Foi desenvolvida uma revisão da literatura sobre cada um dos temas, com maior extensão sobre o valor para o cliente. Em cada um destes foram apontados: uma visão geral dos temas; a discussão conceitual e a relevância teórica e prática de cada assunto; os principais desafios para pesquisa; aspectos relacionados à mensuração; e os desenvolvimentos dos temas no contexto brasileiro. Foi elaborado a partir desta revisão um total de cinco proposições, que geraram dois modelos estruturais aos quais foram agregadas as proposições conceituais associadas aos construtos de benefício e de sacrifício como dimensões de valor para o cliente. Para avaliar os dois modelos, decidiu-se proceder a um levantamento de dados, por meio de um questionário estruturado, junto a estudantes de cursos de pós-graduação lato sensu da área de gestão, na cidade de Fortaleza. Foram coletados 261 questionários, dos quais 248 foram utilizados nas análises. Os modelos foram avaliados a partir da técnica de Modelagem de Equações Estruturais, tendo-se destacado os seguintes resultados: com relação à reclamação, identificou-se que, quanto mais os clientes percebem valor nos serviços, mais se tornam predispostos a reclamar, e mais efetivamente reclamam; quanto ao comportamento de boca a boca, verificou-se que quanto mais valor os clientes percebem, mais são predispostos a tais comunicações, e efetivamente falam mais intensamente e mais favoravelmente. Adicionalmente, foram identificadas algumas dificuldades com as proposições conceituais, e com os antecedentes do valor. Com base nos resultados, são apontadas algumas recomendações para outras pesquisas envolvendo os temas em questão, como forma de superar as limitações identificadas, e de avaliar os problemas identificados em cada um dos temas. / This dissertation has the customer value as the main subject, and the main purpose was to analyze the relationship of value with complaining and word-of-mouth behaviors. The research is justified for the necessity of a scientific analysis putting the three subjects together, in order to make possible a better comprehension of them as elements of the marketing relationship paradigm. This way, it was done a research on the academic literature of each subject, more extensively on customer value. For each subject, it was appointed: an overall analysis; a discussion about the concepts and the theoretical and practical relevance; the main challenges for academic research; aspects of measurement; and the development of researches on the subject in the Brazilian context. From the literature evaluation, five propositions were developed, what generated two different structural models. Conceptual propositions related to the benefits and sacrifices dimensions related to customer value concept were also put in the models. In order to evaluate the two models, a questionnaire was prepared, and the data collected with students of management lato sensu post graduate courses from Fortaleza. A total of 261 questionnaires were collected, and 248 were used in the analysis. Structural Equation Modeling were used to evaluate the models, and the main results were: related to complaining behavior, it was identified that value perceived influences positively the complaining intention, and the action of complaining; related to word-of-mouth, it was identified that value perceived influences positively the word-of-mouth intention, and also the behavior intensity and favorability. In addition, some difficulties were found relating the value conceptual propositions, both with the benefits and the sacrifices dimensions. From the results, some research recommendations involving the subjects were suggested, as a way to solve the limitations of this research, and to evaluate the problems identified in each one of the subjects.

Service quality has always been a tacit assumption within the delivery of academic library services, but since the 1990s demands for accountability from different stakeholders, including the clients, made service quality a highly debated and researched focus in academic libraries all over the world. The scope of the study covers a wide-ranging analysis of discourses underpinning service quality and its accompanying performance indicators in academic libraries. Using the academic library of the University of South Africa as an illustrative case study, this study examines the possible impact of inventory control on the service quality of the academic library in three areas, namely access to information resources, retrieval of information resources and positive implications for sound financial management. The study's findings all point to a positive enhancement of service quality in regard to the three areas mentioned. / Information Science / M. Inf.

Les mouvements périodiques des jambes sont de courts mouvements involontaires qui surviennent de façon périodique au cours du sommeil ou de l’éveil. Ils sont présents dans certains troubles du sommeil, mais également chez des sujets sans plainte reliée au sommeil. Le premier objectif de cette thèse visait une meilleure description de la prévalence de ces mouvements. Nous avons montré que chez les sujets sans plainte de sommeil, la prévalence des mouvements périodiques des jambes en sommeil augmentait de façon importante à partir d’environ 40 ans, tandis que l’index des mouvements périodiques des jambes à l’éveil évoluait avec l’âge selon une courbe en U. Chez les sujets atteints de narcolepsie, on retrouvait davantage de mouvements périodiques des jambes que chez les sujets témoins, mais leur patron d’évolution avec l’âge était similaire. Le deuxième objectif de cette thèse visait l’étude des mouvements périodiques des jambes en relation avec le système nerveux autonome cardiovasculaire. Nous avons non seulement confirmé la présence d’une tachycardie suivie d’une bradycardie lors des mouvements périodiques des jambes durant le sommeil chez les patients atteints du syndrome d’impatiences musculaires à l’éveil et chez les sujets sans plainte de sommeil, mais nous avons également décrit ces mêmes changements de la fréquence cardiaque, quoiqu’avec une plus faible amplitude, chez les sujets atteints de narcolepsie. Finalement, nous avons montré pour la première fois que les mouvements périodiques des jambes en sommeil des sujets atteints du syndrome d’impatiences musculaires à l’éveil et des sujets sans plainte de sommeil étaient aussi associés à des augmentations importantes et significatives de la pression artérielle. / Periodic leg movements are short involuntary movements occurring periodically during sleep or wakefulness. They occur in some sleep disorders, but also in healthy subjects not complaining of sleep problems. The first objective of this thesis was to provide a better description of the prevalence of these movements. In healthy non-complaining subjects, the prevalence of periodic leg movements during sleep increased dramatically from about age 40, whereas the age-related evolution of periodic leg movements during wakefulness followed a U curve. In narcoleptic patients there were more periodic leg movements than in control subjects, but their evolution with age showed the same pattern. The second objective of this thesis was to study periodic leg movements in relationship with cardiovascular autonomic nervous system. We not only confirmed that periodic leg movements during sleep were associated with a tachycardia followed by a bradycardia in restless legs syndrome patients and in healthy non-complaining subjects, but that these heart rate changes were also present in narcoleptic patients, albeit of a lower amplitude. Finally, we showed for the first time that periodic leg movements during sleep in restless legs syndrome patients and in healthy non-complaining subjects were also associated with significant and important rises of blood pressure.
