The LTE technology offers versatile mobile services that use different numbers of resources. This enables operators to provide subscribers or users with differential quality of service (QoS) to boost their satisfaction. On one hand, LTE operators need to price the resources high for maximizing their profits. On the other hand, pricing also needs to consider user satisfaction with allocated resources and prices to avoid “user churn,” which means subscribers will unsubscribe services due to dissatisfaction with allocated resources or prices. In this paper, we study the pricing resources with profits and satisfaction optimization (PRPSO) problem in the LTE networks, considering the operator profit and subscribers' satisfaction at the same time. The problem is modelled as nonlinear multiobjective optimization with two optimal objectives: (1) maximizing operator profit and (2) maximizing user satisfaction. We propose to solve the problem based on the framework of the NSGA-II. Simulations are conducted for evaluating the proposed solution.

The few computer-assisted scheduling and dispatching (CASD) systems evaluated to date do not, in general, provide details on the effects of quality of service. An analysis of the quality-of-service effects of a CASD system in central Illinois is presented. The analysis finds that a variety of service attributes have been positively affected by CASD implementation. Passengers experienced greater on-time rates at both pickup and drop-off, overall satisfaction with the service increased, and customer reporting of ride denials was reduced. On the other hand, the use of CASD to promote higher vehicle productivity resulted in slightly longer ride times. In addition, callers to the system experienced being put on hold more often. On the whole, the conclusion is that quality of service has been positively affected by the implementation of the CASD system.

Construction professionals are the authors on one hand and co-executors of constructionprojects on the other, therefore, the quality of the services expected of them in constructionproject delivery as environmental resource manager is key. This paper investigated whetherquality of service of the construction professionals in Nigeria is influenced by the level ofprofessional fees receivable for services rendered hence their resource management role. Thedeterminants of service quality are identified and their means of evaluation examined usingthe SERVQUAL; instrument used for measurement of the service quality on responses gotfrom a set of questionnaires administered on the construction stakeholders comprising of theconstruction clients on one hand and the construction professionals on the other hand inLagos, Nigeria with a view to assessing the perception of the clients regarding the quality ofservices being received from their construction professionals vis-a-vis clients expectations.The study revealed that there was no significant relationship between the level of fees paidand the quality of service rendered by the construction professionals as the result of theanalysis of variance between service quality gap and the various methods of fees paid is notreflected in the service quality of construction professionals.

Recently, consumers become more critical. They criticize whenever they found the quality of service offered was not according to what had already been promised. On the other hand, quality of service became the sword of marketing program. Thus, these two elements go hand in hand to retain consumers. This research aims to answer some problems regarding quality of service of a photo developer retail outlet. Data gathered from consumers were analyzed by using validity, realibility and weighted mean to indicate the response of consumers towards all elements embeeded within the business. The research results showed that consumers found satisfied with the service given. However, the study suggested several steps to maintain customer satisfaction.

Over the course of his 14-year career at Chicago's Field Museum of Natural History, artist and engraver John Conrad Hansen rendered hundreds of beautiful and accurate scientific illustrations of animals – mostly extinct fossil vertebrates. His principal media were oil paintings, pencil, pen-and-ink and wash drawings. Many of his illustrations have been published in the scientific literature. His oil paintings, on the other hand, were made for display alongside specimens in the Field Museum's exhibits. Despite the quality of Hansen's full-colour reconstructions, few of them have been seen outside the Museum. A small, representative sample of his work is reproduced here, along with a brief account of his troubled life and career.

Ainsworth's Strange Situation

Fourty-nine 12 months old children and their mothers were videotaped in Ainsworth's Strange Situation. Fourty-six of them were videotaped again in the same situation at 18 months with their fathers. Quality of attachment was determined by using Ainsworth's criteria. Fewer children had 'secure' relationships to their parents than in comparable U.S. samples. There was no correlation between infant-mother and infant-father quality of attachment relationship. The results are discussed in terms of parental attempts to cope with cultural demands imposed on them. These specific cultural demands may frequently interfere with the establishment of a securely attached relationship. On the other hand, they may be only transitory and appropriate from an adaptation to culture-specific expectancies point of view.

The multicast quality of service-enabled routing is a computationally challenging task. Despite ongoing research efforts, the associated mathematical problems are still considered to be NP-hard. In certain applications, computational complexity of finding the optimal connection between a set of network devices may be a particularly difficult challenge. For example, connecting a small group of participants of a teleconference is not much more complex than setting up a set of mutual point-to-point connections. On the other hand, satisfying the demand for such services as IPTV, with their receivers constituting the majority of the network, requires applying appropriate optimization methods in order to ensure real system execution. In this paper, algorithms solving this class of problems are considered. The notion of multicast saturation is introduced to measure the amount of multicast participants relative to the entire network, and the efficiency of the analyzed algorithms is evaluated for different saturation degrees.

The recertification of the professional accounting qualification in Estonia: the requirements and quality of CPD As the purpose of a professional qualification should be to ensure quality to employers/customers, appro-priate requirements for professional training should not be too low. On the other hand, too high require-ments for the amount of training would lead to the situation where maintaining the level is expensive and if the labour market does not consider having a professional certificate necessary, recertification will be discarded. The purpose of the research was to identify the factors that influence an accountant’s decision whether to recertify his/her professional qualification or not. The conditions of recertification were ana-lysed and compared to other countries as were the requirements set up for auditors. The results of the survey revealed that in Estonia the decision not to recertify one’s professional qualification was mainly due to not having fulfilled the required number of qualification hours or not having certificates proving one’s participation in qualification training sessions. At the same time, compared to other countries, the requirements in Estonia are very low. So that the increase in the amount of training would not hinder recertification, alternative solutions for Estonia are proposed in the article.
