Websites and an Automated Call Distribution (ACD) system in a call center are both considered important customer relationship technologies. Integrating concepts from information systems quality and trust transference theory, this paper introduces the concept of inter-satisfaction: the extent to which customer satisfaction with a website leads to satisfaction with an ACD and vice versa. It is hypothesized that dissatisfaction with either the website or the ACD influences potential brand-switching behaviors. A model, largely drawing upon concepts of user satisfaction as developed in information system research, is presented. The model is then tested using data from passengers using Low Cost Carriers (LCCs) in South Korea, specifically 366 passengers at the Jeju International Airport, who experienced both their airlines’ website and call center. A structural equation modeling analysis demonstrates that satisfaction with the website transfers to satisfaction with the ACD system, but not vice versa, and that only dissatisfaction with the website creates a brand-switching intention.  相似文献

Ethical instruction is critical for trainee accountants. Various teaching methods, both active and passive, are normally utilised when teaching accounting ethics. However, students’ learning styles are rarely assessed. This study evaluates the learning styles of accounting students and assesses the interaction of teaching methods and learning styles in an ethics instruction environment. The ethical attitudes and preferred learning styles of a cohort (137) of final year accounting students were evaluated pre-instruction. They were then subject to three different teaching methods while studying ethics during an auditing course. When ethical attitudes and preferred learning styles were re-assessed post-instruction, the teaching methods were found to have influenced active learners more than passive ones. Furthermore, when learning styles matched teaching methods used, usefulness was assessed as high but when learning styles and teaching methods differed, usefulness deteriorated significantly. Students displayed a preference for passive learning styles, despite being so advanced in their education. The implications are that instructors should consider learning styles before deciding on appropriate teaching methods, in accounting ethics environments.  相似文献

We introduce deep habits into a sticky-price sticky-wage economy and examine the resulting models ability to account for the impact of monetary policy shocks. The deep habits mechanism gives rise to countercyclical markup movements even when prices are flexible and interacts with nominal rigidities in interesting ways. Key parameters are estimated using a limited information approach. The deep habits model can account very precisely for the persistent impact of monetary policy shocks on aggregate consumption and for both the price puzzle and inflation persistence. A key insight is that the deep habits mechanism and nominal rigidities are complementary: the deep habits model can account for the dynamic effects of monetary policy shock at low to moderate levels of nominal rigidities. The results are shown to be stable over time and not caused by monetary policy changes.  相似文献

The article presents forecasts and analyses aimed at the justification for the modernization of the Russian economy based on innovative products of the engineering industry. Solutions to the following tasks are proposed: to restore the function of innovations of the engineering industry, to provide the innovative and technological development of the production apparatus of the engineering industry, and significantly increase the share of domestic products in the market of investments and consumer goods.  相似文献

Adverse weather is the dominant cause of delays in the National Airspace System (NAS). Since the future weather condition is only predictable with a certain degree of accuracy, managing traffic in the weather-affected airspace is a challenging task. In this paper, we propose a geometric model to generate an optimal combination of ground delay and route choice to hedge against weather risk. The geometric recourse model (GRM) is a strategic Probabilistic Air Traffic Management (PATM) model that generates optimal route choice, incorporating route hedging and en-route recourse to respond to weather change: hedged routes are routes other than the nominal or the detour one, and recourse occurs when the weather restricted airspace becomes flyable and aircraft are re-routed to fly direct to the destination. Among several variations of the GRM, we focus on the hybrid Dual Recourse Model (DRM), which allows ground delay as well as route hedging and recourses, when the weather clearance time follows a uniform distribution. The formulation of the hybrid DRM involves two decision variables - ground delay and route choice - and four parameters: storm location, storm size, maximum storm duration time, and ground-airborne cost ratio. The objective function has two components: expected total ground delay cost and expected total airborne cost. We propose a solution algorithm that guarantees to find the global optimum of the hybrid-DRM. Based on the numerical analysis, we find that ground-holding is effective only when combined with the nominal route. Otherwise, it is optimal to fly on the route determined by the DRM without ground delay. We also find the formula of the threshold ground-airborne cost ratio, which we call the Critical Cost Ratio (CCR), that determines the efficacy of ground delay: the higher the CCR, the more effective the strategies involving ground delay. We conclude that both ground delay and route hedging should be considered together to produce the best ATM decisions.  相似文献

Hospital operating theatres are a critical but costly resource in healthcare processes. Their efficiency and utilisation impact upon hospital finances, clinical effectiveness and patient outcomes. Operations management techniques have now been applied widely to optimise flow. An important challenge is to balance the needs of process flexibility, efficiency and work standardisation with clinical requirements. This paper applies operations management methods to analyse elective orthopaedic surgery at five international hospitals to describe the issues that affect operating theatre productivity. It utilises an innovative method of video analysis to observe patient changeovers over 29 days of surgery and data is analysed to understand the causes of variability and waste. The findings suggest that processes which are standardised via operations management methodologies can improve productivity in a process that exhibits wide variation in practice. There are apparent trade-offs associated with efficiency and clinical concerns such infection control, that lead to different standard process archetypes being utilised. Recommendations for standardising patient changeovers are provided.  相似文献
