This study aims to construct a valid, reliable measurement model for the enhancement process effectiveness in an open source environment. We examine the validity and reliability of an initial list of indicators through two rounds of data collection and analysis from 240 and 750 OSS projects respectively, and come up with a measurement model for the effectiveness of enhancement process comprising four indicators. The implication of this measurement model for practitioners is explained through a numerical example followed by implications for research community.

When applied in a health context, this is known as: health-related quality of life (HRQoL). The assessment of HRQoL is a medical goal; it is used in clinical research, medical practice, health-related economic studies and in planning health management measures and strategies. Obtaining a patient self-assessment with QoL measuring instruments on the platform developed in this project, through friendly software, easy for the user to adapt to, aids the study, promotes the creation of databases, and accelerates its statistical treatment. The possibility of graphically representing results that physician needs to analyse, immediately after the answer collection, makes this assessment a diagnosis instrument ready to be used routinely in clinical practice.

Survey method has been used to attain the objectives of research by including 70 large and medium scale organisations, from state of Punjab in India, in the sample. It was found that Indian manufacturing firms were using IS for operational benefits rather for strategic benefits. Extent of outsourcing IS functions was limited. Organisations were found lacking in planning for IS outsourcing activities. Top management was playing an active role in the purchase of IS-based applications with the major inputs coming from IT department in the organisation. The present study provides useful insights regarding the state of IS outsourcing in the Indian manufacturing sector. Findings of the study indicate that IS outsourcing practices are in nascent stage as IS usage history of Indian manufacturing sector is quite short.

We find that these firms continuously broaden and enhance their product lines by leveraging highly mobile and fungible digital resources and capabilities. In particular, we show that investments of a focal firm in organisational networks create higher switching costs relative to those in public networks, therefore, making revenue generation more sustainable. Our findings suggest that healthcare information providers pursue two key strategies to expand their economies of scope and scale. They first rely on complementarities among their internal resources in order to find new uses for existing products. M&A investments in external resources are primarily used when these firms intend to create new product offerings outside of their current capabilities.

Active database systems can react to the occurrence of some predefined events automatically. In many applications, active rules may interact in complex and sometimes unpredictable ways, thus possibly yielding infinite rule executions by triggering each other indefinitely causing non-termination. Almost all of the work to date on termination analysis for active databases relies on checking that a directed graph called the 'triggering graph' for a set of rules is acyclic. This paper presents new algorithms for detecting termination/non-termination of rule execution using triggering graph.
