Study of Queueing Behaviour in IP Buffers

It is unquestioned that the importance of IP network will further increase and that it will serve as a platform for more and more services, requiring different types and degrees of service quality. Modern architectures and protocols are being standardized, which aims at guaranteeing the quality of service delivered to users. In this paper, we investigate the queueing behaviour found in IP output buffers. This queueing increases because multiple streams of packets with different length are being multiplexed together. We develop balance equations for the state of the system, from which we derive packet loss and delay results. To analyze these types of behaviour, we study the discrete-time version of the “classical” queue model M/M/1/k called Geo/Gx/1/k, where Gx denotes a different packet length distribution defined on a range between a minimum and maximum value.

Management interventions and prosocial behaviours:understanding the mediating mechanisms

Previous research suggests that the attitudes and behaviours of front-line employees (FLEs) significantly influence customers’ evaluations of service quality and customer satisfaction. Therefore, it becomes important to identify the variables that influence FLEs job attitudes and Prosocial ServiceBehaviours (PSBs). The conceptual framework developed from extant literature is presented, which proposes that management interventions (internal communication, training and development and empowerment) have a direct effect on PSBs. In addition, these relationships are mediated by role stress and job attitudes. Implications for service management and future research directions are discussed.

Motivations for servitization:the impact of product complexity

Purpose – The purpose of this paper is to identify the commonalities and differences in manufacturers’ motivations to servitise. Design/methodology/approach – UK study based on interviews with 40 managers in 25 companies in 12 sectors. Using the concept of product complexity, sectors were grouped using the Complex Products and Systems (CoPS) typology: non-complex products, complex products and systems. Findings – Motivations to servitise were categorised as competitive, demand based (i.e. derived from the customer) or economic. Motivations to servitise vary according to product complexity, although cost savings and improved service quality appear important demand-based motivations for all manufacturers. Non-complex product manufacturers also focus on services to help product differentiation. For CoPS manufacturers, both risk reduction and developing a new revenue stream were important motivations. For uniquely complex product manufacturers, stabilising revenue and increased profitability were strong motivations. For uniquely systems manufacturers, customers sought business transformation, whilst new service business models were also identified. Research limitations/implications – Using the CoPS typology, this study delineates motivations to servitise by sector. The findings show varying motivations to servitise as product complexity increases, although some motivational commonality existed across all groups. Manufacturers may have products of differing complexity within their portfolio. To overcome this limitation the unit of analysis was the strategic business unit. Practical implications – Managers can reflect on and benchmark their motivation for, and opportunities from, servitisation, by considering product complexity. Originality/value – The first study to categorise servitisation motivations by product complexity. Identifying that some customers of systems manufacturers seek business transformation through outsourcing.

Within-role, extra-role and anti-role behaviours in retail banking

Purpose: This paper aims to explore front line employee performance in retail banking and presents distinct components of employee performance, including extra-role and sabotage behaviours. Design/methodology/approach: Data was collected from Irish bank employees. Usable responses were received from 404 respondents and subjected to exploratory factor analysis. Structural Equation Modeling (SEM) was used to undertake a confirmatory factor analysis of the emergent five-factor model. Findings: Results indicate front line employee performance is multi-faceted and comprised of civility, assurance and reliability, customer orientation, as well as extra-role behaviour and anti-role behaviour, or sabotage. Research limitations/implications: This exploratory study focuses on the Irish banking sector. To explore the generalisabilty of results, replication studies among other samples of branch banking employees in other countries are in order. Moreover, our survey is limited to the views of branch employees. We advocate research among bank managers and customers to triangulate potentially divergent views about performance. Practical implications: Findings have implications for recruitment, training and rewards. To ensure new hires are service minded, managers must consider their potential for extra-role or sabotage behaviour. Employees who demonstrate extra-role behaviours must be rewarded to encourage the adoption of such behaviours. Managers must also seek to minimise job stress in order to curtail anti-role behaviours. Originality/value: This paper offers insights into employees' views about their own performance at the front line. It extends the conceptualisation of service quality, by considering extra-role behaviour and sabotage as components of employee performance. © Emerald Group Publishing Limited.

In marketing literature a lot of studies have been created focusing on understanding and measuring e-service quality (e-sq) and online-customer satisfaction. The aim of the study is to summarize these concepts, analyse the relationship between e-sq and customer’s loyalty, which increases the competitiveness of the companies, and to create a valid and reliable scale to the Hungarian market for measuring online-customer satisfaction. The base of the empirical study is the E-S-QUAL and its second scale the E-RecS-QUAL that are widely used multiple scales measuring e-sq with seven dimensions: efficiency, system availability, fulfilment, privacy, responsiveness, compensation, and contact. The study is focusing on the websites customers use to shop online.

As over the last decade internet has become a significant channel, in parallel its customers have built some expectation about the quality of different websites and online services. Therefore the marketing literature should focus on the dimensions of e-service quality (e-sq) and online-customer satisfaction. This study first resumes with different concepts of e-sq, which are the principles of the online-customer satisfaction’s measurement. Than the different e-sq measurement methods are reviewed and the dimensions of E-S-QUAL and ERecS- QUAL scales are deeply explained. The study is focusing on concepts relating to web shops. The next part of the article includes two empirical studies. The first is about the situation of satisfaction measurement at Hungarian companies. The other one analyzes the most relevant relationships between the dimension of e-sq and customer satisfaction based on the E-S-QUAL and E-RecS-QUAL scales for measuring e-sq and briefly outlines the reliability and validity of these scales. The main purpose of this empirical research is to summarise the managerial and practical implications.

Anarchy In The Airways

In his dialogue - Anarchy In The Airways - Joseph C. Von Kornfeld, Assistant Professor, College of Hotel Administration, University of Nevada, Las Vegas initially states: “Deregulation of the airline industry has brought about financial vulnerability for the traveling public. The author analyzes the situation since that point in time and makes recommendations for some solutions.” In this article, Assistant Professor Von Kornfeld, first defines the airline industry in its pre-regulated form. Then he goes into the ramifications and results of deregulating the industry, both in regards to the consumer, and in deregulation’s impact on the airlines themselves. “The most dramatic consequence of the pressures and turbulence of airline deregulation has been the unprecedented proliferation of airline bankruptcies,” Von Kornfeld informs. “Prior to the deregulation of the U.S. airline industry in 1978, U.S. air carriers operated in a business environment that was insulated from the normal stresses and strains of open competition. They were restricted from actively competing with fares and routings by the Civil Aeronautics Board (CAB),” Von Kornfeld says. In leveling the playing field, Von Kornfeld offers, “Each carrier was restricted to specific geographic routes, with those routes limited to two or three competing carriers. The only thing that set carriers apart in this CAB defined atmosphere was their ability to either advertise, or to enhance their level of service; or both. “…ultimately paid for by the passenger through fare increases sanctioned by the CAB,” Von Kornfeld states. “Airline service standards were unquestionably superior during the regulated environment,” Von Kornfeld renders an interesting observation. He does mention, however, that carrier safety was also considered a concern immediately prior to, and then after deregulation. “The major controversy focused on the allegation that safety and maintenance standards would be compromised due to the financial pressures brought about by an openly competitive environment,” Von Kornfeld says. Pricing, as well as labor unions are important factors in the equation, and Von Kornfeld addresses their relevance in the deregulated environment. “The primary rationalization for deregulation was to facilitate a more openly competitive environment. The increased competition was to ultimately have benefitted the consumer. Ironically, that’s not entirely the case, Von Kornfeld elaborates. In addressing some of the negative aspects of airline deregulation, Von Kornfeld suggests that some sort of federal re-regulation may be in order.

Hotel Guest e-questionnaires: Implications for Feedback and Relationships

This paper examines the reliability and efficacy of hotel guest e-mail questionnaire compared to the paper questionnaire in the Asian Pacific context. Conducted inPerth,SingaporeandPenang, cities with mature hospitality and tourism industries and a representation of chain and independent deluxe hotels, this exploratory qualitative study examines hotelier views of e-mail guest communication derived from content analysis of guest questionnaires format and content and in-depth interviews with senior hoteliers. The findings indicated that e-questionnaires manifested as e-mails, as a direct replacement of the paper questionnaire, appear to be premature given divergent hotelier views and shortcomings in e-mail response administration. If properly executed, e-mail can play an increasingly important adjunct role to the paper guest questionnaire as a part of a multi-channel approach. The balance/relationship between ‘high tech’ and ‘high touch’ needs to be maintained: the latter can enhance the latter but should not undermine it.

A Study of Satisfaction Level of Hong Kong Tourists with Hot Springs Hotels and Resorts in Guangdong, China

The research reported here aimed at examining Hong Kong tourists’ level of satisfaction with hot springs hotels and resorts in Guangdong, China. Primary data were collected and service quality and tourist satisfaction levels were measured using the SERVQUAL model. The empirical findings indicate that most tourists are satisfied with the service quality of these hotels and resorts. Among the different dimensions of service quality, empathy receives the highest score. Overall satisfaction receives a score only slightly better than average. The results also reveal significant relationships among customer satisfaction level, loyalty, and recommendation.

The Effects of Teppanyaki Restaurant Stimuli on Diners’ Emotions and Loyalty

This research examines the influence of restaurant stimuli (i.e., chefs, service staff, other customers, food quality, and atmospherics) on diners’ emotions and loyalty to teppanyaki restaurants. In teppanyaki restaurants, chefs take orders from diners, prepare food in front of diners, and serve dishes to diners. Although the importance of chefs has been acknowledged by scholars, empirical research on the influence of chefs on diners has been scarce. To augment the literature on how chefs influence diners, this research incorporates “chef’s image” into an extended Mehrabian-Russell model (M-R model) to conceptualize diner loyalty to teppanyaki restaurants. A total of 308 diners from Taiwan were recruited. After examining their completed questionnaires, this study found that chef’s image, service quality, and food quality can affect the positive and negative emotions of diners. Moreover, other diners and restaurant atmospherics affect only the negative emotions of diners. Both positive and negative emotions can affect diner loyalty to teppanyaki restaurants. In addition, the managerial implications of this study are discussed.
