Pakistan's mobile phone market is one of the world's fastest growing markets with a subscriber base of 137 million users. Competition in the country's telecommunication industry is dominated by four players and customer demand is high. In addition Pakistan is the first country in South Asia to have implemented Mobile Number Portability (MNP) in March 2007. MNP is a facility that allows mobile subscribers to switch between service providers without changing their existing phone numbers. Mobile phone service provider's selection may be influenced by various factors. Therefore this research was undertaken to explore factors affecting MNP and to determine which factors were most influential in the selection of mobile phone service providers in a developing economy like Pakistan. Moreover the study also probed into differences in customer perceptions between pre-paid and post-paid customers. This exploratory study is based on primary data collected from 300 customers using services of different cellular companies who had experienced MNP facility. Factor analysis was carried out on obtained data and reliability of the resultant scale was verified to achieve the objectives of the study. The outcome of this research provided a concise framework of the various dimensions of customer choice. Contrary to previous researches the result of this study indicated that infrastructural services customer relationships call quality and promotional packages were the most important factors affecting MNP. However price of services was found less important factor in selection of telecommunication service providers. This study also showed that pre-paid and post-paid customers can be significantly different for many value-added services and promotional tools. (C) 2017 The Authors. Published by IASE.

Günümüzde, bir dergi kapağına veya bir televizyon reklamına baktığımızda yüksek olasılıkla gösterilen kadınlar uzun boylu ve gerçeklikten uzak ölçüde zayıftır. Medya ve toplumumuz, medya tarafından standartları oluşturulmuş bu güzellik kavramına uymayanları kabul etmemeye başlamıştır. Bu araştırmanın amacı, medyadaki beden imgesinin genç kadınlar üzerinde oluşturduğu öz güvensizlik, yeme bozuklukları ve bedenlerinin yetersizlikleri fikirlerini bulmak ve kadınlar üzerindeki etkilerini gözlemlemektir.Araştırma genç kadınlara yapılan anketlerden elde edilen bilgiler doğrultusunda rakamlarla desteklenmiştir. Araştırma sonuçları göstermiştir ki medyanın rolü ve mütemadiyen yansıttığı mükemmel beden ve daha zayıf olunması gerekliliği fikri yüzünden genç kadınlar görünüş ve bedenleri için çok endişelidir. Medyadaki beden imgesi kadınlarda sadece beden öz güvensizliğini artırmakla kalmaz, dahası yeme bozuklukları ve öz saygı eksikliğine yol açar.
