The Australian Government is meeting the challenge of water scarcity and climate change through significant on-farm infrastructure investment to increase water use efficiency and productivity, and secure longer term water supplies. However, it is likely that on-farm infrastructure investment will alter energy consumption and therefore generate considerable greenhouse gas (GHG) emissions, sugges...

Organizations in both the private and public sectors have been struggling to determine the appropriate investments to make for protecting their critical intellectual property. As a result, cybersecurity investment strategies at the macro level (overall strategic investment in systemor enterprise-wide protection) and the micro level (how to allocate the tactical security elements across componen...

Information security operations necessary to protect the confidentiality, integrity, and availability of an organization’s information systems against attacks represent substantial investments in technologies, tools, and human resources. Typically, the relationship between the supplier of an information system and its users is regulated by a Service Level Agreement, and the supplier must determ...

This paper analyzes the information security investment decisions by a firm with two correlated information assets. When information assets are correlated, a firm may face additional losses compared to a loss from a single breach, and the probability of security breach on one set may increase the probability on the other. We model the security investment of a risk-taking firm as well as risk-ne...

This paper uses real options analysis, specifically a hybrid Monte Carlo simulation – decision tree analysis as well as a binomial tree analysis, to look at optimal decisionmaking for investment by a small community wind farm under uncertainty. In particular, the uncertainty due to forecasting of electricity prices and the potential for carbon pricing are considered. Two options are considered:...

Transportation project prioritization uses performance measures that are related to the transportation asset, its operations, and its environment. However, in the state of practice, evaluation does not consider directly the likelihood of natural or man-made threats, the infrastructure resilience, or the consequences of the infrastructure damage in the event that the threat occurs. Thus, during ...

Information security operations ― necessary to protect the confidentiality, integrity, and availability of an organization’s information systems against attacks ― represent substantial investments in technologies, tools, and human resources. Typically, the relationship between the supplier of an information system and its users is regulated by a Service Level Agreement, and the supplier must de...

Although there is a lot of country and regional variation, the overwhelming story across much of Africa and Asia is one of more small farms, shrinking farm sizes and increased income diversification. Despite growth, sometimes quite rapid growth, in national per capita incomes, there is little sign yet of a shift to the patterns of farm consolidation and matching levels of rural-urban migration ...

Farm structure and optimal farm size have always attracted the interest of research as they constitute some of the intense problems of farm efficiency and farm income. Although several approached have been employed to handle with this problem a real options approach can significantly contribute on this matter. This article provides an empirical example of applying real options approach in inves...

In most of the developing countries, lack of resources and little market accessibility are among the major factors that affect small farming household food security. This study aims to investigate the status of small farming households' food security, and its determinants including the role of market accessibility factors in enhancing food security at household level. In addition, this study al...
