31	Customer-based brand equity of the major cellphone network service providers amongst principal estate agents in the Gauteng province of South Africa Mentz, Hendrik 14 September 2011 (has links) This study investigates the customer-based brand equity of the major cellphone network service providers (Vodacom, MTN and Cell C) amongst principal estate agents registered with the Estate Agency Affairs Board in Gauteng. Secondary research covered the marketing environment of the major service providers. An extensive study of literature on branding, brand management and brand equity measurement was undertaken. An empirical study was conducted. Telephone interviews were used for initial contact and screening. An invitation to participate in the survey, with a link to a questionnaire, was e-mailed to qualified respondents. Cell C users were excluded from the quantitative analysis. There were several significant findings: Vodacom and MTN users are alike in terms of personal and estate agency-related demographics. With the exception of age and gender, the sample fits the stated descriptors of individuals in the LSM seven to LSM ten groups. Cronbach‘s alpha coefficient confirmed a high level of reliability (0.870) for the summated measurement scale developed as an indicator variable of customer-based brand equity and Vodacom and MTN‘s rating on the summated scale did not differ at a statistically significant level. The service provider used proved to be an important driver of loyalty, but overall satisfaction with the cellphone service does not differ statistically significantly between Vodacom and MTN users. Vodacom has established a much more favourable positioning on the brand association statements evaluated. Factor analysis identified five brand association dimensions that should be considered for measurement of brand associations. Multiple regression analysis identified the brand as a product dimension as the best predictor of customer-based brand equity. Vodacom received more favourable brand performance ratings than MTN. Factor analysis identified six brand performance dimensions that should be considered for inclusion when measuring brand performance. Multiple regression analysis identified the easy to use and one-stop-service dimensions as the best predictors of customer-based brand equity. The customer-based brand equity of the user group is moderate (16 out of 25, or 64%). / Business Management / D. Com.

32	Investigating the Single Category Belief Problem in a Hybrid Product Aziz, Salma 18 August 2011 (has links) Existing research suggests that when consumers encounter hybrid products or boundary-spanning products with attributes belonging to multiple categories, consumers tend to generate inferences based on only a single product category. Reliance on a single category for inferencing is termed as the “single category belief problem” which has been regarded as a vital marketing challenge because it leads consumers to underestimate the true utility of a hybrid product as certain product attributes are ignored. Our objective was to explore whether single category beliefs manifest in consumer choice for a hybrid product when strategically placed within varying contexts. The research used discrete choice experiment (DCE) to test hypotheses. Our research confirms that the single category belief is evident in consumer choice. We also found that the context the hybrid product is placed within has a major influence on what consumers preferred the most. Depending on the context a hybrid product was seen in had significant influence on how consumers evaluated product attributes and made purchase decisions. The findings for this research may be very beneficial for marketers.

35	Channel Modeling Applied to Robust Automatic Speech Recognition Sklar, Alexander Gabriel 01 January 2007 (has links) In automatic speech recognition systems (ASRs), training is a critical phase to the system?s success. Communication media, either analog (such as analog landline phones) or digital (VoIP) distort the speaker?s speech signal often in very complex ways: linear distortion occurs in all channels, either in the magnitude or phase spectrum. Non-linear but time-invariant distortion will always appear in all real systems. In digital systems we also have network effects which will produce packet losses and delays and repeated packets. Finally, one cannot really assert what path a signal will take, and so having error or distortion in between is almost a certainty. The channel introduces an acoustical mismatch between the speaker's signal and the trained data in the ASR, which results in poor recognition performance. The approach so far, has been to try to undo the havoc produced by the channels, i.e. compensate for the channel's behavior. In this thesis, we try to characterize the effects of different transmission media and use that as an inexpensive and repeatable way to train ASR systems.
