Enterprise systems (ES) are important business software which can be difficult to implement, while the failure to account for organisational culture can lead to projects that are expensive and late. However most of the existing research has focused on national level culture. As such little is known of how organisational culture influences the implementation of enterprise systems. This ongoing r...

Student modelling systems must operate in an environment in which a student’s mastery of a subject matter is likely to change as a lesson progresses. A student model is formed from evaluation of evidence about the student’s mastery of the domain. However, given that such mastery will change, older evidence is likely to be less valuable than recent evidence. Data ageing addresses this issue by d...

Virtual or Managed Learning Environments (VMLEs) cannot be fully effective unless well-integrated with existing campus information systems. Institutional planning for the UK Research Assessment Exercise (RAE) has provided an unexpected impetus at the University of Bristol. The DataHub, a reporting database created initially to back-end a locally developed Web application (IRIS) to support the R...

Time on task is an important predictor for how much students learn. However, students must be focused on their learning for the time invested to be productive. Unfortunately, students do not always try their hardest to solve problems presented by computer tutors. This paper explores student disengagement and proposes an approach, engagement tracing, for detecting whether a student is engaged in...

To find the current level of a student’s knowledge, we use a sequence of problems of increasing complexity; if a student can solve a problem, the system generates a more complex one; if a student cannot solve a problem, the system generates an easier one. To find a proper testing scheme, we must take into account that every time a student cannot solve a problem, he/she gets discouraged. To take...

Increasingly, higher education institutions are exploring the potential of learning analytics to predict student retention, understand learning behaviors, and improve student learning through providing personalized feedback and support. The technical development of learning analytics has outpaced consideration of ethical issues surrounding their use. Of particular concern is the absence of the ...

We examine whether stringent formal sector borrowing requirements in developing countries restrict credit access and the potential of asset-collateralized loans. When a Kenyan dairy cooperative exogenously replaced high down payments with loans collateralized by the asset itself a large water tank loan take-up increased from 2.4% to 41.9%. In contrast, substituting joint liability requirements ...

METHODS The authors designed a survey instrument to examine the effect of involvement in a student-run free clinic project (SRFCP) on medical student self-reported attitudes toward the underserved and interest in primary care. From 2001-2010, first-and second-year medical students in an introductory service-learning elective course rated each of 15 statements on a seven-point Likert scale pre/p...
