Examining motivation of IT vendors to share knowledge with clients

To reduce information technology (IT) development costs, more firms have begun to outsource IT-related activities by partnering with IT vendors. As knowledge is a valuable asset in IT development, knowledge sharing between vendors and business clients becomes critical. However, the motivation behind IT vendors’ willingness to share knowledge with client firms is not sufficiently understood. To shed light on the nature of knowledge sharing within vendor–client partnerships, we examine the influence of performance feedback and managerial mindset on vendors’ motivation to share knowledge with their clients. We adopt a multi-method approach involving both a scenario-based field experiment with 164 vendor managers (Study 1) and a field survey of 112 vendor managers involved in IT development (Study 2). We find that when vendors’ performance exceeds their aspiration levels, they are motivated to share knowledge with clients. Such motivational effects are more pronounced for vendor managers exhibiting abstract mindsets. Our study is of significant value to researchers and practitioners, affording both groups a keener, deeper, and more robust appreciation for how knowledge sharing in vendor–client partnerships can be managed more effectively.

Exploring best practices in public–private partnership (PPP) in e-Government through select Asian case studies

e-Government has emerged as a popular governance reform in recent years, to improve the productivity of the government and quality of services provided by it to various stake-holders. However, e-Government implementation is hampered by certain roadblocks such as lack of financial resources, lack of technical and soft skills, etc. Public–private partnership (PPP) has emerged as a viable model to counter these factors, apart from improving the economic sustainability of e-Government projects. PPP essentially implies sharing of risks and rewards of a venture. Successful implementation of PPP in e-Government requires the adoption of some key best practices, and incorporation of the learning obtained from previous PPP experiences. Four successful “PPP in e-Government” projects, implemented in Asia, are discussed to highlight the best practices and key learning obtained from each project. This is intended to highlight the necessary steps to be taken, especially in an Asian setting, to implement a successful PPP in e-Government.     

Shaping Up: Boot Camp and Other Programs Addressing Professional Development Needs of Science Librarians

Scientists work collaboratively with online tools, relying almost exclusively on online resources and sharing publications freely online while generating and utilizing large datasets. As a result, librarians charged with providing services to the scientific community face both opportunities and challenges in keeping up in this electronic, digital environment. To meet these challenges, library leaders from the five campuses of the University of Massachusetts System established an on-going e-Science initiative. This initiative focuses on increasing awareness and understanding of the principles of e-Science while improving general knowledge within different scientific disciplines. Programs of varying lengths and focus provide local and affordable professional development opportunities that improve the working librarian's ability to better serve scientific researchers and students.
