A value-based approach to prioritise non-functional requirements during software project development
- Authors: Alex J. Ruiz-Torres, JosÃ© Humberto Ablanedo-Rosas, Somnath Mukhopadhyay
  Pages: 363 - 382
  Abstract: Non-functional requirements determine the characteristics of a software product or service as a whole. The research described in this paper presents an empirical framework involving respondents of both the project and the business organisation, in order to select and prioritise a list of non-functional requirements for implementation during software project development. The assessment process takes into consideration the extent of relative value addition while making trade-off in selection of non-functional requirements for inclusion in the project's requirement set. The final results are expected to be beneficial to both the business and the project organisation by identifying and implementing the desired non-functional requirements that contributes to business value in a cost effective manner.

Exploring technology acceptance for online food services
- Authors: Tugrul U. Daim, A. Nuri Basoglu, Deniz Gunay, Ceren Yildiz, Fredy Gomez
  Pages: 383 - 403
  Abstract: This paper explores the factors which may affect customers' choices for online shopping, and thus help online food sellers innovate. A theoretical framework based on technology acceptance model was developed for this sector. A survey instrument was used to validate the framework. We found that the most important factors affecting online food shopping are: the speed of the website, fast response time on online services and kindness and quality of the personnel. Contrary to our estimations, some extra features such as a dietician support for menus, a list of nutritive values for every meal and displaying the ingredients of the meal were found unnecessary by the customers who buy food through online services.

An RBV and real options-based soft OR heuristic for solution strategising
- Authors: Suvankar Ghosh, Marvin D. Troutt, Alan Brandyberry
  Pages: 404 - 422
  Abstract: This paper develops a heuristic for applying the abstract and complex theories of real options and the resource-based view (RBV) to provide managerial prescription on promising technology solutions to business problems. We draw upon the tradition of soft operational research (OR) with its reliance on graphical techniques to develop a decision-making matrix called the CUReO Grid for identifying preferred solutions under different conditions of decision context uncertainty and the capability of the firm to exploit the technologies under consideration. Our grid is obtained by a two-stage mapping of the real options available in a technology solution, such as options for altering scale and scope or for strategic growth, to a two-dimensional space defined by contextual uncertainty and firm capability. We illustrate our general methodology by applying it to two very different but major contemporary problems: enterprise integration in information technology and lean production in operations management.

Optimal spectrum utilisation in cognitive network using combined spectrum sharing approach: overlay, underlay and trading
- Authors: Ayoub Alsarhan, Anjali Agarwal, Ibrahim Obeidat, Mohammad Bsoul, Ahmad Al-Khasawneh, Yousef Kilani
  Pages: 423 - 454
  Abstract: Cognitive radio technology enables unlicensed users (secondary users, SUs) to access the unused spectrum. In the literature, there are three spectrum sharing paradigms that enable SUs to access the licensed spectrum. These access techniques include underlay, overlay and spectrum trading, and have their own drawbacks. To combat these drawbacks, we propose a new approach for each of them and merge them into one combined system. Our overlay scheme provides quick access to the unused spectrum. We propose a new cooperative sensing protocol to reduce the likelihood of interfering with PUs. In order to enable SUs for transmitting simultaneously with PUs, we suggest using our underlay scheme. Our trading scheme allows PUs to trade the unused spectrum for the SUs that require better quality of service. The new combined scheme increases the size of spectrum in the cognitive network. Simulation results show the ability of the new scheme to serve extra traffic.

Gender preferences of efficiencies and ethical issues: commercial, personal, and governmental applications of RFID-based implants and technologies
- Authors: Ayoub Alsarhan, Anjali Agarwal, Ibrahim Obeidat, Mohammad Bsoul, Ahmad Al-Khasawneh, Yousef Kilani
  Pages: 455 - 492
  Abstract: Significant advancements in RFID-related applications and its scanning technology has become an increasing subject for academic research. Analysing a sample of employed business professionals, representative of the service industry located within the metropolitan section of Pittsburgh, PA, a major corporate headquarters revealed a number of significant gender differences when considering the myriad operational and ethical issues associated RFID-related implementations, especially concerning microchip implants. Overall, male business professionals had a perceived greater awareness of RFID-related technological applications, while females were more concerned about job loss due to such technological innovations, local government has more control over technological innovations, and felt that such technology was useful in reducing the threat of personal identity theft. In general, most respondents felt that RFID-embedded microchip implants were potentially important in dealing with effectively dealing with criminal elements in society and keeping domesticated animals safe, but generally felt that too many potential issues associated with commercial and governmental misuse exists in order to allow for widespread, unregulated implementations into society.
