The National Aeronautics and Space Act of 1958 established the National Aeronautics and Space Administration (NASA) and charged it to “provide for the widest practicable and appropriate dissemination of information concerning ... its activities and the results thereof”. The search for innovative methods to distribute NASA′s information led a grassroots team to create the NASA Technical Report Server (NTRS), which uses the World Wide Web and other popular Internet‐based information systems.

Fraud is a global economic menace which threatens the survival of individuals, firms, industries and economies, and the mobile money service is no exception. This paper aims to explore the main causes of fraud in the mobile money services in Ghana and the measures to combat the menace by the key stakeholders connected to the mobile money services. The paper is motivated by recent reports of numerous fraudulent transactions on the mobile money platform, and the need to clamp down these nefarious transactions with effective and practical measures to sustain the service.

A thorough review of existing studies on fraud risk relating to mobile money services was done revealing a paucity of literature on the subject. Primary data were gathered using an interview guide to explore the magnitude of the problem based on the views of employees of mobile money operators, mobile money agents, banking supervisors from Bank of Ghana, employees of partnering banks, employees of National Communications Authority and mobile money subscribers.

The study revealed that fraud in mobile money services is caused by weak internal controls and systems, lack of sophisticated information technology tools to detect the menace, inadequate education and training and the poor remuneration of employees. These factors disrupt the growth, and the smooth-running of the services. To curb this menace, a detailed legal code and internal fraud policy should be developed and used by mobile money operators and partner banks. Adequate training for mobile money agents should be encouraged coupled with public awareness campaigns to educate stakeholders especially the mobile money subscribers on the tricks of the fraudsters.

With the chosen research methodology and limited sample size, the findings may not reflect the views of all the stakeholders connected to the mobile money services. Therefore, future studies on this subject are entreated to use research methods which embrace larger samples to get more details about this menace.

The study will assist in tackling the mobile money fraud to sustain the service in the foreseeable future.

This paper contributes to scanty literature on fraud relating to the mobile money services by drawing lessons from a middle-income country.

To enhance an entrepreneur's business network through the integration of the social network concepts and design principles of virtual communities.

This study documents the design and initial deployment of a virtual community case, Innovation Information Infrastructure, based on social network concepts.

Basic design principles, deployment strategy, and future directions for social network‐based virtual communities are presented.

Because of resource and time constraints, only basic content service, communication tools, and transaction functions were implemented in the initial deployment. Future extensions of this study may include development of a personalized and intelligent information retrieval system utilizing data mining techniques, development of advanced communication features to promote active participation, and creation of automatic social network‐tracking tools to monitor an individual's network evolution.

Sample designs are provided for researchers who are interested in conducting a similar study.

This study serves as a starting‐point for how theories from social network and virtual community research streams can be applied in creating a virtual community that facilitates transformation of knowledge into products and services, which in turn lead to greater economic prosperity.
