Adaptive packet classification for constant perceptual quality of service delivery of video streams over time-varying networks

We study the role of dropout risk in dynamic signaling. A seller privately knows the quality of an indivisible good and decides when to trade. In each period, he may draw a dropout shock that forces him to trade immediately. To avoid costly delay, the seller with a low-quality good voluntarily pools with early dropouts, implying that the expected quality of the good increases over time. We characterize the time-varying equilibrium trading dynamics. It is demonstrated that the maximum equilibrium delay of trade is decreasing in the initial belief that the good is of high quality.

Service Gap

This study analyzes the gap between expected and perceived services by ship passengers at the Sri Bayintan Port, Kijang, Riau Archipelago. The purpose of the paper is to examine the gap between expected and perceived service delivery by ship passengers in the Sri Bayintan Port. To test the service gap, ServQual variables as postulated in Parasuraman, Zeithaml & Berry (1988) were used. The variables include tangibility, reliability, responsiveness, assurance, and empathy. Data were collected using a sample of 98 passengers, who were chosen at random. Research results showed that there is a significant difference between expected and perceived service delivery among passengers who use Sri Bayintan port. In particular, findings of this study showed that passengers were not satisfied with the quality of service delivery they received in Sri Bayintan Port.

Business To Consumer

In an m-commerce setting, the underlying communication system will have to provide a quality of service (QoS) in the presence of two competing factors—network bandwidth and, as the pressure to add value to the business-to-consumer (B2C) shopping experience by integrating multimedia applications grows, increasing data sizes. In this chapter, developments in the area of QoS-dependent multimedia perceptual quality are reviewed and are integrated with recent work focusing on QoS for e-commerce. Based on previously identified user perceptual tolerance to varying multimedia QoS, we show that enhancing the m-commerce B2C user experience with multimedia, far from being an idealised scenario, is in fact feasible if perceptual considerations are employed.

Acute Healthcare

In this current 21st-century global competitive market, employee empowerment plays a significant role in building the internal resource-based capacity of business survival towards meeting and exceeding ever-increasing market needs. The tertiary health institutions saddled with the responsibility of providing acute healthcare services significantly require effective commitment of their healthcare workers in promoting quality of service delivery towards achieving result-oriented healthcare quality assurance outcome. However, the Nigerian health sector has been characterised with diverse challenges in sustaining quality assurance due to lack of leadership commitment in empowering caregivers in the sector effectively. To a large extent, this has weakened the adequate performance of employees, and also, contributed to the observed increase in morbidity and mortality rate in the Nigerian health centres. This aim of this paper is to critically analyse the impact of employees' empowerment on the perceived quality of service delivery in the context of the Nigerian healthcare institutions.
