Mobility management for vehicular user equipment in LTE/mobile femtocell networks

Vehicular User Equipment (UE) performance during mobility faces two issues relating to signaling and transmission, namely Handover (HO) and link adaptation. This paper shows that both processes are experiencing degradation during mobility and that vehicular UEs suffer from call drops and loss of connections. Therefore, this work presents an effective technique using Mobile-Femtos to improve vehicular UEs' HO process and link quality. Results show that vehicular UEs attached to a Mobile-Femto achieved better signalling and Link Ergodic capacity and as a consequence the outage probability was reduced. The achieved results indicated that deploying Mobile-Femtos under 25dB Vehicular Penetration Loss (VPL) has improved the vehicular UE Link Ergodic capacity by 1% and reduced the signal outage probability by 1.8% compared to the eNB direct transmission. Consequently, Drop Calls Probability (DCP) and Block Calls Probability (BCP) have been reduced by 7% and 14% respectively compared to the direct transmission from the eNB

How KOLs influence consumer purchase intention in short video platforms:Mediating effects of emotional response and virtual touch

In recent years, Key Opinion Leader (KOL) marketing opens up a new mode of social commerce by effectively integrating social networking and marketing since it has been successfully taking advantage of KOL’s high popularity to promote products. This study expands the stimulus-organism-response (S-O-R) model by combining the communication persuasion theory with the flow experience theory. Our model considers the characteristics of KOLs and published content features as independent variables, consumer perception as the mediating variable and consumer purchase intention as the dependent variable. This study also refines the measurement dimensions of each variable and analyzes KOL impacts on consumer purchase intention on short video platforms. After analyzing 357 valid questionnaires, we find that the variables –reputation, perceived fit, aesthetic quality and content richness have significant impacts on consumer purchase intention where virtual touch and emotional response play intermediary roles. This study provides insights into KOL marketing

An empirical investigation of total quality management in Libya: a proposed guideline of implementation

Rapid socio-economic and technological changes have urged the implementation of new approaches to procure construction projects. Total Quality Management (TQM) is one of the approaches that contribute towards ensuring that projects are being delivered to the stakeholder requirements. This study identifies critical success factors (CSFs) that affect the implementation of TQM in the Libyan Construction Industry (LCI) and develops guidelines which help companies implement and maintain quality management systems. To achieve these aims, the research employed both quantitative and qualitative methods. Based on a thorough review of literature, a questionnaire was developed and distributed to 200 managers. Data from 130 completed questionnaires were then analysed using Principal Component Analysis (PCA), which reveals the internal structure of the data in a way that explains the dimensions of TQM implementation in LCI. The results identify five reliable and valid TQM dimensions, namely organisation management, communication to improve quality, training and development, employee involvement and recognition, and culture. Supported by relevant literature and interviews with a number of managers, they provide the basis for developing the guideline for successful implementation of TQM in Libyan construction companies

Decision Support Based on Bio-PEPA Modeling and Decision Tree Induction: A New Approach, Applied to a Tuberculosis Case Study

The problem of selecting determinant features generating appropriate model structure is a challenge in epidemiological modelling. Disease spread is highly complex, and experts develop their understanding of its dynamic over years. There is an increasing variety and volume of epidemiological data which adds to the potential confusion. We propose here to make use of that data to better understand disease systems. Decision tree techniques have been extensively used to extract pertinent information and improve decision making. In this paper, we propose an innovative structured approach combining decision tree induction with Bio-PEPA computational modelling, and illustrate the approach through application to tuberculosis. By using decision tree induction, the enhanced Bio-PEPA model shows considerable improvement over the initial model with regard to the simulated results matching observed data. The key finding is that the developer expresses a realistic predictive model using relevant features, thus considering this approach as decision support, empowers the epidemiologist in his policy decision making

TQM Practices in Public Sector : Case of Finnish Healthcare Organizations

This study aims to discuss the evolution, principles, and stages of total quality management (TQM) in public health care organizations. It also makes a comparison that how case organizations think about quality and TQM along with its applicability within public sector. The study can be categorized as qualitative research. The data is collected from semi structural interviews of the informants and the concerning documents, which consist of strategy, policy papers and audit reports of the case organizations. Altogether there are two case organizations. Furthermore, data is analyzed with the help of content analysis. Most vital issues in TQM practices are its comprehensiveness, and its application in such a way which is appropriate for the organization, with a logical way of operation and the participation of management and personnel. Training, guidance, teamwork, involvement and learning are imperative for achieving a continuous improvement culture and are vital elements when adopting TQM. Managers should learn from the experience of TQM implementers by studying expected challenges and pitfalls. They should also pay more attention to the crucial role of all stakeholders in the TQM implementation. The study could be quite valuable from a strategic perspective in providing guidelines to build up a proper plan for TQM practices more promptly. The paper also manages to shed light on TQM practices of public service organizations by comparing their current approaches to quality.fi=vertaisarvioitu|en=peerReviewed

Framework for a Hospitality Big Data Warehouse: The Implementation of an Efficient Hospitality Business Intelligence System

order to increase the hotel's competitiveness, to maximize its revenue, to meliorate its online reputation and improve customer relationship, the information about the hotel's business has to be managed by adequate information systems (IS). Those IS should be capable of returning knowledge from a necessarily large quantity of information, anticipating and influencing the consumer's behaviour. One way to manage the information is to develop a Big Data Warehouse (BDW), which includes information from internal sources (e.g., Data Warehouse) and external sources (e.g., competitive set and customers' opinions). This paper presents a framework for a Hospitality Big Data Warehouse (HBDW). The framework includes a (1) Web crawler that periodically accesses targeted websites to automatically extract information from them, and a (2) data model to organize and consolidate the collected data into a HBDW. Additionally, the usefulness of this HBDW to the development of the business analytical tools is discussed, keeping in mind the implementation of the business intelligence (BI) concepts.SRM QREN IDT [38962]FCT projects LARSyS [UID/EEA/50009/2013]CIAC [PEstOE/EAT/UI4019/2013]CEFAGE [PEst-C/EGE/UI4007/2013]CEG-IST - Universidade de Lisboainfo:eu-repo/semantics/publishedVersio

Toward an integrated conceptualization of the service and service system concepts: a systems approach

Service and service systems concepts are fundamental constructs for the development of the emergent SSME, ITSM, and Service Oriented Software (SOS) knowledge streams. A diversified literature has provided a richness of findings, but at the same time, the lack of standardized conceptualizations is a source of confusion to IT practitioners and academics. Given this problematic situation, we pose that a systems approach is useful to address it. In this article, we review and synthesize key studies in these knowledge streams to design: (i) a framework to characterize both concepts under a system view and, (ii) harmonized definitions (e.g. identification of shared and essential properties) for such fundamental concepts. Our main contribution is scholastic, but we are confident that the posed conceptual artifacts can be further used to elaborate standardized definition for the IT service and IT service system constructs, as well as analysis tools for describe real service systems

Service science,management, engineering, and design (SSMED): an emerging discipline -- outline and references

The growth of the global service economy has led to a dramatic increase in our daily interactions with highly specialized service systems. Service (or value-cocreation) interactions are both frequent and diverse, and may include retail, financial, healthcare, education, on-line, communications, technical support, entertainment, transportation, legal, professional, government, or many other types of specialized interactions. And yet surprisingly few students graduating from universities have studied anything about service or service systems. Service Science, Management, Engineering, and Design (SSMED), or service science for short, is an emerging discipline aimed at understanding service and innovating service systems. This article sketches an outline and provides an extensive, yet preliminary, set of references to provoke discussions about the interdisciplinary nature of SSMED. One difficult challenge remaining is to integrate multiple disciplines to create a new and unique service science
