The Water Framework Directive 2000/60/EC draw attention to Water Quality Monitoring Networks (WQMN) that allows the acquisition of information regarding water streams. Information could be acquired by a spatial and/or temporal approach. However, there is a cost for monitoring water quality. Hence, to determine the spatio-temporal design of the network, the Economic Value of Information must be known to undertake a cost-benefit analysis. In this study, we show how the calculation of the EVOI can help the network manager to answer questions such as: is the cost of monitoring justified? How to allocate a budget between adding a monitoring station or increasing the frequency of measurement of existing stations?

The determination of value of information or information systems is a basic issue for information management. In order to solve it several questions must be answered like: what is the object of valuation; how is value defined and measured; and what constitutes a coherent and usable method for valuation. In this paper an approach is outlined that combines the information commodity approach, activity-based costing, and graph modelling. The first is used to define the object of analysis (an information commodity) and the nature of value (the demand value at the marketplace). The third allows the modelling of business processes in terms of activities and cost relations between activities. The second enables the assignment of costs to activities modelled in the graph. Together they constitute a coherent and usable method for determining the value of IS. This is illustrated by means of a case study.

Using a multi-theoretical approach, this study seeks to examine the determinants of corporate web-based investor relations (IR) activities for companies listed on Amman Stock Exchange. Jordan provides an interesting context to pursue the objectives of this study because it provides insights into how listed companies are voluntarily responding to recent government and financial market regulators initiatives to encourage the use of the internet and to keep financial market participants informed about corporate activities. A survey analysis is conducted to examine online reporting practices of Jordanian listed companies. The explanatory analysis relies on logistic, ranked and normal scores ordinary least squares (OLS) regression analyses and identifies ten explanatory variables that may affect the existence and level of web-based IR disclosure; company size, profitability, government ownership, institutional ownership, number of shareholders, growth prospects, age, industry type, auditor type, and equity need. Results reveal that the existence of web sites is positively related to company size and industry (Financials) while the extent of web-based IR disclosure is significantly positively related to size, governmental ownership, institutional ownership, number of shareholders, and industrial type (Financials); however, it is negatively related to company age.

This study analyzed what are enablers to adopt web-based Personal Health Records (PHR) from patients' perspective while many studies are conducted from providers' perspective. Patients may consider Perceived Value of Information, Perceived Worthwhileness of Searching, Privacy, Information Trust, and Security before adopting web-based PHR. By using HINTS (Health Information National Trends Survey), this study found out that Perceived Value of Information is the most critical enabler for patients to adopt web-based PHR. Privacy, Information Trust, and Security are also enablers to adopt web-based PHR. But, Perceived Worthwhileness of Searching is not statistically significant to explain adoption of web-based PHR. However, Perceived Value of Information is strong antecedent of Perceived Worthwhileness of Searching. Based on this study, patients are more likely to adopt web-based PHR when they realize that web-based PHR provides valuable and reliable information with protecting privacy and security.
