Smartwatches are wearable mini-computers equipped with sensors. They are intended as smartphone companions providing information access related to health, location, social media, and more. Recently, information systems research acknowledged smartwatches as fashion products and wonder whether this hype will fade due underutilization. Yet, adoption r...

Proof-of-Work (PoW) is a common mechanism used to validate peer-to-peer transactions and maintain highly secured immutability of the blockchain. However, this mechanism has been criticized due to its inefficient use of computing resources and its limited usefulness. In this paper, we propose the Proof-of-Useful-Work (PoUW) as an alternative mechani...

Article
Extant research in information systems relies heavily on career anchor theory (CAS) as a lens to examine occupational choices and outcomes in information technology. Yet, the empirical results are inconclusive and the power of the theory in predicting IT occupations is rather weak. With the growing demand for IT professionals, it becomes imperative...
Chapter
Providers of e-government systems and policymakers recognize that usability and adoption are key success indicators of e-government services. Borrowed from the field of e-commerce, several models were proposed and tested in the literature to evaluate users' adoption of e-government services in different contexts. This chapter examines users' satisf...
Article
Purpose: Social Network Sites (SNS) have been common applications attracting a large number of users in Qatar. Current literature remains inconclusive about the relationship between SNS usage and users’ academic performance. While one stream confirms that SNS usage may lead to addiction and seriously affects individuals’ academic performance, other...

Evaluating users' satisfaction of e-Government services has been addressed by numerous studies. These mainly looked at e-Government users as citizens who are nationals and comply with the local culture of the governments providing these services. However, the GCC region has a particular culture stemming from the social structure and working environ...
Conference Paper
Gamification has shown to be a valuable approach that enhances participants’ engagement. In education, enhanced student engagement has proven to increase their learning effectiveness. In business, gamification permits employee innovations and helps organizations achieve various business objectives. However, the application of gamification in public...
Article
This study aims at exploring users' satisfaction with the traffic violation e-Service provided by the Ministry of Interior in Qatar. The paper presents the findings of a quantitative survey that covered over 300 users of the traffic violation e-Service and reflects on satisfaction based on the four dimensions of the COBRA framework (Osman et al. 20...
Article

Workflow technology has been proven an enabler of numerous benefits for the private and public organisations including cost reduction, efficiency savings in terms of time and cost, increased capability, faster processing, reductions in errors and work iterations, service quality and customer satisfaction. Public sector has endorsed these benefits b...
Conference Paper
Full-text available
Mobile government application and services refer to governmental functions that are available to mobile devices, such as smart phones or personal digital assistants, to the users anytime/anywhere. M-Government and m-Participation are emergent concepts used to represent the evolving field of public administration functions provided as mobile service...
Conference Paper
This paper aims to propose PMWF model, a new workflow model to automate ubiquitous policy making processes and facilitate citizen participation. While workflow technology has been widely adopted in public sector, the use of technology is mostly limited to supporting back-end administrative business processes. PMWF model targets front-end policy mak...
Article
While centralised approach has been considered to provide superior performance workflow coordination than market-based approach, most of the extant comparisons have been performed on the assumption that the working environments are static. This paper aims to compare the performance of the two approaches in task allocations of mobile business proces...
Conference Paper
While two main approaches, namely the centralized and the market-based approaches, have been used and compared in the literature for task allocation problems, uncertainty and dynamism imposed in the mobile task allocation problem (MTAPs) require new techniques for comparing these two approaches due to the limitations of traditional mathematical mod...
Article
Full-text available
Centralized approach has been adopted for finding solutions to resource allocation problems (RAPs) in many real-life applications. On the other hand, market-based approach has been proposed as an alternative to solve the problem due to recent advancement in ICT technologies. In spite of the existence of some efforts to review the pros and cons of e...
