Customer satisfaction is a key concern in any business strategy. It is often assumed that customer satisfaction can be enhanced using e-services. E-service is defined as interactive service received via the Internet (Jiang et al., 2013). E-service has contributed to business-to-consumer (B2C) e-commerce by providing on-demand solutions to customers. The relationship with the customer is enhanced by introducing self-service options, product customisation and variety. However, there may also be negative impacts, such as techno-stress and lack of online customer assistance. The primary aim of this research was to develop a conceptual framework to describe the correlation relationship between the factors that influence customers’ adoption of e-services. Organisations use the Internet to attract customers, to conduct financial services and obtain information. This research focussed specifically on online shopping. The Grounded Theory research methodology was chosen for its flexibility and iterative comparison of data. A quantitative survey was conducted to determine the relative significance of the factors uncovered by the Grounded Theory methodology and to validate the hypothesis of the conceptual model. Customer adoption is attained where customer satisfaction is high, where the customer sees value in the service, and where there is customer loyalty or trust. To date, research has focussed primarily on developed countries. Many challenges face South Africa as a Newly Industrialised Country (NIC). The negative factors facing developing countries in terms of e-service adoption include: lack of infrastructure, economic constraints and an emergent socio-political framework. The aim of this research was to build a conceptual model for explaining interrelationships between the identified factors that have an impact on customer e-service adoption. The customer’s perception of technology-driven services affects the organisation’s reputation, which in turn affects profitability. This research will be beneficial to ii managers in local organisations that thrive on e-services. An understanding of customer preferences will lead to improvement of customer services in South Africa. / Art History, Visual Arts & Musicology / D. Litt. et Phil. (Art History)

Magister Chirurgiae Dentium - MChD / Purpose: To assess the oral health status of 4-15-year-old schoolchildren in the Western Region of the Eastern Cape Province, by determining the prevalence of dental caries, periodontal disease, dental fluorosis, malocclusion and oral mucosal lesions and to create baseline data for planning oral health services in this region. Materials and Methods: The prevalent analytic survey was undertaken on 822 schoolchildren between the ages of 4-15 years in 27 different schools. The sample size selected for this region by the Department of Statistics, University of Pretoria, for the National Oral Health Survey of 1999/2000 was used. The data on 209, 210, 209 and 194 scholars in the 4-5, 6, 12 and 15-year-old age groups respectively were collected. The World Health Organization's (1997) criteria were used to determine the prevalence of caries, periodontal treatment needs, the dental fluorosis, malocclusion and prevalence of oral mucosal lesions. Six calibrated and trained examiners recorded the data on a survey form. The WHO survey forms were used for data collection. The data were analysed and processed by the author on Microsoft Excel 2000. Results: The sample size consisted of 1.35 % Asian, 51.89 % Black, 26.07 % Coloured and 20.06 % White scholars. Nearly equal amounts of males (48.3 %) and females (51.7%) were examined. The dental caries prevalence in the primary dentition of 4-5-year-olds with an average age of 4.43 years was 40.67%, with a mean dmft of 3,56. The dental caries prevalence in the permanent dentition of6-, 12- and 15-year-oldage groups was 67.62%, 46.05% and 67.92% respectively. The mean DMFT for 6-, 12- and 15 year olds were 0.05, 1.19 and 2.02 respectively. Gender differences and differences in prevalence of dental caries between the populations groups were recorded. The Coloured children experienced the highest dental caries prevalence. In the 4-5- and 15-year-old groups the males were affected more than the females by dental caries. Prevalent differences were recorded between rural and urban areas in the same population group. The prevalence of periodontal disease in 373, 12-15-year-olds was 79.09%. Only 4.02 % were in need of dental hygiene instructions and polishing. Dental education, dental hygiene instructions, dental scaling and polishing were needed by 75.07% of the children. Dental fluorosis prevalence in 450, 6-15-year-olds was 13.03%. Dental fluorosis did not affect 86.97% of the scholars; 10.63% had mild fluorosis and 2.05% was severely affected. The mean fluoride concentration in the drinking water in this region were 1.07 mgIL, ranging between 0.3-3 mgIL. Definite malocclusion was recorded in only 0.48% of the 12-year-old group, whom needed elective treatment. In the 12-year-olds, 99.52% needed no or slight treatment for no or minor malocclusions. The majority of children had no oral mucosal lesions (91.55%). The prevalence of oral mucosal lesions was 8.5% in this survey. The most frequent conditions were traumatic lesions (1.96%), dento-alveolar abscess (1.22%) and herpes labialis (1.22%). The intra-examiner reliability for caries, dental fluorosis, periodontal treatment needs and prevalence of malocclusions was 97.66%, 100%, 88.89% and 86.67% respectively. The inter-examiner reliability was 98.75%, 98.34%, 100%, 100% and 100% respectively for the five examiners. Conclusion: This survey indicated a higher prevalence of dental caries in the primary dentition (63.48%), than the permanent dentition (41.3%). The mean dmft was 3.65 and the DMFT 1.2, which indicated a low mean caries experience for these children. The WHO goal for the year 2000 for the 6-year-olds of 50% being caries free has not reached for only 32.56% were caries free. The mean DMFT of 1.2 for 12-year-olds in this survey is below the WHO goal of a mean DMFT of 1.5 or less. The lack of available preventative service provision, were ) indicated by the low percentage of fissure sealants (2.8%). The need for dental treatment was highlighted by the need mostly for one-surface restorations. Preventative treatment, two-surface fillings and extractions were also needed. Periodontal disease was a major public oral health concern for this region for a prevalence of 79.09% was recorded for the 12-15-year-olds. The majority of the children affected by periodontal disease (75.07%) were in need of professional cleaning and calculus removal. The prevalence of dental fluorosis was 8.2%, 19.87% and 13.05% for 6-, 12- and IS-year age groups respectively. The prevalence of malocclusion was 0.48% for the 12-year-old group. The prevalence of oral mucosa lesions was 8.5% for 4-15-year-old schoolchildren. Therefore, the conclusion can be made that dental fluorosis; malocclusions and oral mucosal lesions were no public concern in this region. The major public oral health concerns were dental caries in the primary dentition and periodontal disease in all age groups. Recommendations: Dental services in this region should be directed towards prevention of dental caries in the primary dentition and periodontal disease in all age groups. The focus of dental services should be primarily on preventative programs and treatments. The public dental treatments needs indicated in this survey, namely scaling and polishing, restorations and extractions, consists of the primary health care package delivery. Currently, no evaluation tool exists to monitor the efficiency of oral health programs, no baseline data for the Province exists. Therefore, the urgent need for dental research and oral health service planning and delivery are recommended.

La tesi si colloca nell'ambito di studi sulla fraseologia nell'inglese prodotto da apprendenti. Presenta uno studio empirico delle sequenze di parole più ricorrenti in un corpus di inglese prodotto da apprendenti di livello avanzato durante chat asincrone in contesto universitario italiano. Secondo la letteratura d'area, sia nella lingua scritta che in quella parlata, le sequenze di parole degli apprendenti rivelano una scarsa attenzione alla variazione del registro a seconda del mezzo di comunicazione usato. Al fine di verificare la presenza di questa caratteristica in un tipo di comunicazione che si trova in posizione intermedia tra i due poli del continuum esistente tra parlato e scritto, la presente ricerca ha analizzato quantitativamente e qualitativamente le sequenze di parole più frequenti nel corpus di comunicazioni mediate dal computer (CMC) raccolto nell'ambito della presente ricerca. Successivamente, le sequenze più frequenti sono state confrontate con quelle estratte da due corpora di interlingua inglese prodotta da apprendenti italofoni, uno di testi scritti (ICLE, Granger et al. 2002) e uno interviste orali (LINDSEI, Gilquin et al. 2010 ). Il confronto ha rivelato che le sequenze più ripetute dagli apprendenti hanno caratteristiche distintive nei vari media e supporta solo in parte i precedenti studi in materia. Ciò è probabilmente dovuto sia alle caratteristiche di informalità e immediatezza della comunicazione mediata dal computer, che ai vantaggi motivazionali e al diverso tipo di elaborazione linguistica connaturato alla CMC. Per l'apprendente la CMC non presenta la stessa pressione comunicativa del parlato e, allo stesso tempo, egli ha la possibilità di monitorare la propria produzione in quanto distanziata da sé dal mezzo elettronico. / The present dissertation contributes to studies of phraseology in learner English. It is an analysis of recurrent sequences of words in a corpus of learner Computer-mediated Communication. English, collected by means of asynchronous chats in an Italian university context. Previous research has argued that the use of recurrent word sequences plays a major role in learner English fluency both in writing and in speech, and is one of the factors behind learner English register failures. Using a corpus-driven approach, the study analyses the most frequent word sequences extracted from the specially compiled Learner Chat Corpus (LCC). To determine the level of adaptation of learner English to different registers, data regarding 3-word sequences from LCC is compared with the Italian subcomponents of a well-known corpus of learner writing (ICLE, Granger et al. 2002) and a corpus of learner speech (LINDSEI, Gilquin et al. 2010 ). The cross-corpus comparisons provide evidence that learners employ combinations which make their English suitable to the mode they are using for communication. Quantitative and qualitative findings from the present research support only in part previous studies of learner English in terms of recurrent sequences. This is probably due both to the informality and spoken-like quality of CMC, and to its motivational advantages and processing differences connected to the fact that learners can monitor their output while communicating because learner language production is distanced by the electronic means.

1 ABSTRACT This thesis describes the theatre reform at the turn of 19th and 20th century in its wider sociocultural concept. It focuses on the reaction of theatre to the modernistic crisis of European culture and society. Modernism is understood here according to its wider thematic and chronological definition. Modernism is based on the conception of machine civilization as it was defined by a Polish sociologist Jerzy Jedlicki. Jedlicki places the rise of modernistic cultural formation into the second half of 18th century which is when a steam engine was invented and it was a time of social turbulence and changes in human spirituality. Another theoretical frame of the thesis is created by utopia phenomenon as it was defined by Jerzy Szacki. Second half of 20th century is considered to be the end of modernism, inasmuch the utopic visions which had been placed on theatre faded away. The main topic of the thesis is Juliusz Osterwa's and Mieczyslaw Limanowski's theatre studio Reduta. It was founded in Warsaw in 1919 and it was to a great extend inspired by Moscow theatre studios of Stanislavsky and by Polish theatre sources (Stanislaw Wyspianski). By studying selected examples, the thesis studies Reduta as a realisation of modernistic utopia when theatre was supposed to carry a special mission in renaissance of...
