AbstractThis study examines the production and perception of corrective focus in South Kyungsang Korean, using phone number strings. It shows that focus prosody varies greatly by tonal pattern (HHL, HLL, LHT, LHL) within phrases. Prosodic focus in High-initial phrases was clearly produced and accurately recognized, compared to that in Low-initial phrases. Additionally, the identification rate of HLL was higher than that of HHL, mainly because the focused initial H of the HHL contrasted with the second H within phrases, in terms of pitch. The results confirm that the encoding of prosodic focus is not uniform within a language; rather, focus prosody within a language can vary depending on the tonal pattern of an utterance.

Mobile number portability (MNP) across telecommunication networks entails the movement of a customer from one mobile service provider to another. This, often, is as a result of seeking better service delivery or personal choice. Churning prediction techniques seek to predict customers tending to churn and allow for improved customer sustenance campaigns and the cost therein through an improved service efficiency to customer. In this paper, MNP predicting model using integrated kernel logistic regression (integrated-KLR) is proposed. The Integrated-KLR is a combination of kernel logistic regression and expectation-maximization clustering which helps in proactively detecting potential customers before defection. The proposed approach was evaluated with five others, mostly used algorithms: SOM, MLP, Naïve Bayes, RF, J48. The proposed iKLR outperforms the other algorithms with ROC and PRC of 0.856 and 0.650, respectively.

Purpose: The purpose of this article is to assess the switching costs impact on the customer retention in the Lebanese telecommunication industry. Design/methodology/approach: Based on previous literature around customer retention and switching costs, a qualitative survey was conducted on one of the two operators managing the telecommunication market in Lebanon. Focus groups were organized to capture the point of view and perspective of top managers of the operator, results were then coded, and analyzed. Findings: Due to the current duopoly and status quo of the Lebanese telecommunication market, owned completely by the government and managed by two operators sharing the market equally and offering nearly the same portfolio, technologies and network coverage, the switching costs include only the time and effort needed to switch to the other operator, the financial fees to be paid upon buying a new subscription, the attachment to mobile number, and the relational loss from breaking bond with the current provider. Research limitations/implications: Focus group sessions were conducted with managers of one of the two telecom operators in Lebanon, and it might be relevant to interview the managers of the other operator as well. This topic was tackled from the provider’s point of view; it would be interesting to check the customers’ point of view. Practical implications: Managers in the Lebanese telecommunication industry can prepare marketing strategies including customer retention programs and well-designed switching costs to protect and increase their market share once this sector induces more competition either with the introduction of the number portability service or with the privatization of this sector in Lebanon. Originality/value: The customer retention and switching costs constructs are not yet studied in the Lebanese telecommunication market, and also due to the saturation in this industry, customer retention is becoming an imperative topic to all operators in this business.
