Exploring the Acceptance of Ubiquitous Computing-Based Information Services in Brick and Mortar Retail Environments Exploring the Acceptance of Ubiquitous Computing-based Information Services in Brick and Mortar Retail Environments An Integration of UTAUT2 and Media System Dependency Theory Vom Promotionsausschuss der Technischen Universität Hamburg zur Erlangung des akademischen Grades Doktorin der Wirtschafts- und Sozialwissenschaften (Dr. rer. Pol.) genehmigte Dissertation von Sara Kheiravar aus Tabriz 2018 I Erster Gutachter: Herr Prof. Dr.Thorsten Blecker Zweiter Gutachter: Herr Prof. Dr. Christian M. Ringle Tag der mündlichen Prüfung: 19.06.2018 II Acknowledgment Doing a PhD and writing a dissertation is an enjoyable and fulfilling but at the same time a long and rough journey; loaded with many moments of excitement and motivation but also that of exhaustion and disappointment. Without academic and emotional support of many people along this journey I wouldn’t be able to successfully complete it. First and foremost, with deep sense of gratitude, I wish to thank my advisor, Professor Thorsten Blecker, for his academic support, insightful discussions, and constructive criticism. I would also like to thank Professor Christian M. Ringle for accepting to be my second advisor. He was always generous with his time answering my questions and giving invaluable feedbacks on my work. Even though this dissertation was a big milestone in completing my PhD, it might not do justice summarizing my experience at the Institute of Business Logistics and General Management (LOGU) of TUHH. My experience at LOGU was nothing short of amazing for which I am indebted to my great colleagues, faculty and staff of LOGU, many of whom became my true friends ever since we met at the institute. A special acknowledgment goes to my officemates: Semah Ibrahim Ben Abdelaziz and Ahmed Ziad Benleulmi whose support especially during survey design and data collection was invaluable. In addition, I would like to thank Hella, Herman, and Thorsten who provided me with the best imaginable warm and inviting environment upon my arrival in Hamburg. Since my first day in Hamburg I have felt at home and since then they are like family to me. Finally and most importantly, I am endlessly grateful to my family. I could not be the person I am today without them. My dear parents, Hamideh and Belal, unconditionally and generously supported me in every imaginable way to reach my dreams. They inspired me to love and enjoy learning, and taught me that it is only with persistence and hard work that one could achieve her dreams. My lovely sisters, Shirin, Solmaz, and Salma, and brothers, Mohammadhassan, and Khaled, were always there to motivate and cheer me up. Finally, my best friend and husband, Philipp, whom I cannot thank enough was an outstanding emotional support and a great academic advisor. He patiently listened to each and every one of my presentations, discussed III ideas, and shared the passion for research with me. I am eternally blessed to have him by my side.

University of Sci. & Tech., M.D. University, Rohtak, India Hisar, India Abstract- With the rapid advancement in field of networking and communications, no aspect of human life is untouched. Commercial activities are also affected by the new advancements. Traditional commercial activities are changed and modified with the passage of time. Firstly, the age of E-Commerce arrived, then M-Commerce. Now, after E-Commerce and M-Commerce, the age of Ultimate Commerce is arrived. Any time/ Always/ Anywhere service providing is the key to this ultimate or ubiquitous commerce. This paper studies the concept of ubiquitous computing and its adaption to commerce with new issues associated. Keywords- Ubiquitous computing, Ubiquitous commerce. I. INTRODUCTION Ubiquitous commerce, also referred to as „u-commerce‟ is a new paradigm that broadens and extends the Internet usage in today‟s environment. With the rapid development of ubiquitous computing and mobile communication technologies, the traditional business model is changing drastically. As a logical extension of e-commerce and m-commerce, Watson proposed the concept of ubiquitous commerce (u-commerce) in 2000. As the next generation business model, it immediately gained a lot of attention. U-commerce emerges as a continuous, seamless stream of communication, content and services exchanged among businesses, suppliers, employees, customers, and products. It will enable interactions and transactions to happen anywhere and at any time without being constrained to stay connected through power and telephone lines.

  • UPS – an Ubiquitous Proximity Eservice for Trust Collaboration
    UPS – An Ubiquitous Proximity eService for Trust Collaboration Yuan-Chu Hwang1 and Soe-Tsyr Yuan2 1 Department of Information Management, National United University, Taiwan No. 1, Lien Da, Kung-Ching Li, Miao-Li 360, Taiwan, R.O.C. [email protected] 2 Department of Management Information Systems, National Chengchi University, Taiwan No. 64, Sec. 2, ZhiNan Rd., Wenshan District, Taipei City 11605, Taiwan, R.O.C. [email protected] Abstract. Ubiquitous e-service is one of the most recent links in the chain of evolution that has characterized the different eras of the internetworking environment. The ubiquitous proximity e-service highlights the collective effort focused on collecting the user group’s power as the reference for ubiquitous trust decisions. In this paper, we define the ubiquitous proximity e-service and discuss the significance of ubiquitous proximity e-service. Simulation outcomes for trust decision quality enhancement show significant improvement in all kinds of environment settings. The ubiquitous proximity e-service makes it possible for users to collaborate with the nearby user groups for establishing a reliable and trustworthy interaction environment. It also facilitates and empowers the potential benefits of various ubiquitous e-service applications. 1 Changes of Proximity in the U-Commerce Era The ongoing developments of ubiquitous commerce have brought human life into a new era. Classic social science studies long ago demonstrated that proximity frequently increases the rate of individuals communicating and affiliating in organizations and communities [1,4]. Proximity also develops strong norms of solidarity and cooperation. While advanced telecommunication technologies have led some to conclude that the problem of distance has been overcome, others argue that proximity remains essential to group functioning and that new technologies cannot eliminate the challenges faced by members of geographically-dispersed teams.

Chandra Sekhar** * Assistant Professor, Department of Computer Science Engineering, Pragati Engineering College, Surampalem, Kakinada, India ** Assistant Professor, Department of Computer Science Engineering, Pragati Engineering College, Surampalem, Kakinada, India Abstract: Ubiquitous computing eliminates the bottlenecks of conventional business in such a way that users get a thrilling experience as well as their purpose is also served.The main underlying principle in ambient intelligence is that computing ,communication ability is stored in smart devices which can be objects ,locations, people. Conducting online business with smart devices increases savings in overall cost for all stakeholders involved. Though reliability is a challenge research work in this direction has already been initiated by the major bodies working in this area. Index Terms: Ambient, EDI, Smart, VMI & Ubiquitous 1. Introduction: In present business era, smart services adopt themselves according to market scenarios .As market scenarios are dynamic, so the design of the devices offering smart services should be flexible. This element of flexibility in the design of smart devices has inherent challenges in themselves which sometimes reduce the quality of service for the device. Nevertheless the advantages weigh over these minor challenges while deploying and using the smart devices. An emerging trend was set in military grounds by the Department of Defence (DoD), USA by making use of RFID tags at container level to supply the inventory products to minimize the lead time when demand was made.

With the rapid advancement in field of networking and communications, no aspect of human life is untouched. Commercial activities are also affected by the new advancements. Any time/ always/ anywhere service providing is the key to this ultimate or ubiquitous commerce. Commerce that offers unique and personalized service to every customer individually using ubiquitous networks is called u-commerce. U-commerce is abbreviation that stands for ubiquitous commerce, also called ubicomp or ultimate commerce. U-commerce represents the next phase of commence, which is initiated by electronic commerce (e-commerce) and propagated by mobile commerce (m-commerce).In this paper, we look into the basic construct or building blocks of U-commerce and what are the obstacles faced in its implementations. U-commerce is combination of e- commerce, m-commerce, television, voice and silent commerce. It can be seen as extension of current types of commerce, but not as their replacement. Main u-commerce characteristics are described using the four u-constructs: ubiquity, universality, uniqueness, and unison. Although U-commerce brings many benefits the principal obstacle to u-commerce development and adoption are customer concerns for their privacy protection.
