One of the most important sectors that plays key role for grasping developed condition is banking sector. Banks like other institutions also look for augmenting their profits and increasing their strength by expansion. The designing of bank must involve selection of those that have sufficient success potential. Hence, from several factors of success, the following three criteria factors have been: selected-customer satisfied, one dimensional, and product fully functional. These factors offers three question multi criteria group extracted from a 16 norms. Also, three criteria factors have been studied over a period of five years and important criteria for evaluating the norms. The Analytical Hierarchy Process (AHP) has been employed to calculate the success potential of each norm. The empirical data comprises the longitudinal survey of the agricultural banking of the Semnan province. The paper, also, finds that product fully functional is placed as the first priority.展开更多

Scott (2000) stresses the requirement of aesthetic and semiotic content in a creative product, instead of creativity. But, how many of retailers and salespersons in heritage product believe the semiotic as knowledge to present the product and opportunities in their selling? According to Kotler (2000) a good personal selling will provide a detailed explanation or demonstration of the product. The message can be varied by the salesperson to fit the motivations and interests or each prospective customer. So, the purpose of this paper is to closely examine the level of awareness among retailers and salesperson toward the important of semiotic knowledge as part of strategic persuasion in a selling process. This survey study will develop a sample among retailers and salesperson in Kuala Terengganu as a respondent who give the feedback to fulfill the research questions.展开更多

Accordingly, the paper proposes that performance could be improved by properly managing differences (gaps) that are usually found between customers' expectations and of suppliers perception with respect to services delivered. The paper also proposes that gaps in the relationship between customers and suppliers could be analyzed using mapping techniques. The paper points to the possibility of finding perception gaps and expectation gaps in the interrelated value attributes of goods and/or services; namely quality, cost, and time of delivery of goods or services to customers. In addition, the paper suggests that those gaps may impact on the performance from the perspectives of quality, cost, and speed of delivery of the service. It is envisaged that this research could assist management in controlling cost and avoid wastage and improve organizational performance.展开更多

The major advantage of the flying boats was its endless runway (i.e., ocean or lake) and resultant possibilities for larger aircrafts than land-based airliners. Airlines such as Pan Am made large investments in the 1930s for flying boats, their special terminals by the water, and the worldwide flying-boat air route network. However, in the late 1940s to early 1950s, the flying boats suddenly disappeared due to the rapid development of land-based large airliners and long runways, according to the previous studies. The author conducted historical research on this topic, and found another reason: rapid decline in the high-income population who used to travel by flying boat scheduled flights. Also found was a recent surge of the luxury market, and steady increase in the cruise-ship passengers. Hence, there could be implications for revival of the flying boat flights as luxury cruise, rather than as scheduled flights.展开更多

As a second point, there is a description and a classification of the different kinds of innovation. The object of this template is a scientific examination of the interrelation between innovation and the companies' future development. Today's markets are changing rapidly. The environment alters faster and faster. Business companies are forced to adapt to these changing conditions. They have to develop new and adjusted products to be successful on these markets. Companies are offering their products on markets. The more customers' requirements those products fulfil, the more likely they will be bought. Innovation can be described as a process of transforming a concept into a product, good, or service. Real innovation is seldom, though. More often, innovation is a result of a known solution being transferred into a new context. There are different forms of innovation. In general innovation can be classified in: basic innovation, product improving innovation, product adjusting innovation, imitation and pretended innovation. These different kinds of innovation can occur within a company as a process, or in a market as a newly developed product. The future of a company depends in many ways on the newly developed products, which in turn are depending on the needs of the customers. Those needs are not always known and needs could also be generated by inventing new technologies. Companies have to consider the development of new products and manufacturing processes in order to stay successful.展开更多

In literature, there are many studies showing how a company's brand affects customer loyalty. Less attention has been paid to the relationship between e-commerce website loyalty and e-customer loyalty. This paper can be included in a stream of research that applies the construct of loyalty to e-commerce. Thus, this study aims to analyze, within the electronic market, the elements influencing and determining the trust and loyalty of the e-customers. This research consists of a descriptive study carried out utilizing the survey method. The population in this study includes 421 e-customers of Italian online multi-brand portals. The instrument of data gathering was a web-questionnaire and the data analysis was based on regression. Findings show a positive relationship between three factors (website technological level, e-service quality, and brand) and e-customer trust. Furthermore, the correlation, among the three variables, trust as mediating variable, and e-customer's loyalty, has been revealed. Therefore, it can be basically assumed that trust builds e-customer loyalty.展开更多

This paper has proposed assessing the quality of food services in the President Restaurant performed by applying Servqual instrument designed on the basis of customer's expectations and perceptions on analyzed components. Over 70% of respondents have a favorable perception on the quality of services. However you can see a slight difference between perceptions and expectations regarding the serving speed, waiter's professionalism, hygiene of room service and inventory objects, the reason being related to the lack of staff.展开更多

However, M-banking still faces resistance that may hamper customers' adoption in Egypt. Following a mixed method approach, this study involves two main phases. First, a quantitative Consumer survey is conducted in the form of 350 structured questionnaires to identify the main barriers towards m-banking. Then, decision makers in 5 different public and private banks are interviewed in order to find similarities and difference, and identify service providers' roles regarding these barricrs. Questionnaire data was statistically analysed using independent T-Test, Chi-squares, frequencies and cross tabulations, while interview data was interpretively analysed. Results enabled the researchers to identify the risk, usage, and tradition as the most m-banking barriers that discourage m-banking adoption in Egypt as seen by the two main players.展开更多

A full-scale two-degree-of-freedom quarter car experimental set-up was constructed to study the vehicle suspension. On-off skyhook controller and Fuzzy-Lyapunov skyhook controller (FLSC) were employed to control the input current for MR damper so as to achieve the desired damping force. Tests were done to evaluate the ability of MR damper for controlling vehicle vibration. Test results show that the semi-active MR vehicle suspension vibration control system is feasible. In comparison with OEM damper, on-off and FLSC controlled MR dampers can effectively reduce the acceleration of vehicle sprtmg mass by about 15% and 24%, respectively.展开更多

Although a series of achievements have been formed, the deeper research is still needed in the following aspects: how to build parameter estimation model of various variables based on the interaction among customer assets elements and how to get the scientific and available measured data. In order to solve these problems, this paper, based on the characteristics of customer relationship in Business to Business (B to B) enterprise and the analysis of the variable factors in the interactive models will systematically and practically use the seemingly unrelated regression method to construct three main parameters estimation models in the customer assets measurement model, and prove the feasibility of the model through a case study. Research results show that measurement model system constructed by this method solves the problem of interaction and germination among parameters influencing factors. At the same time, factors concentration simplifies data sources to ensure the reliability and objectivity of the data, and thus improve the accuracy and feasibility of the estimation of customer assets value.展开更多
