Indeed, due to their simplicity and ease, they are one of the first methods used to analyze gathered data.

Digital signatures are by far the most prominent mechanisms to detect violations of integrity. When signing rights are delegated, the integrity protection is gradually weaker as the delegatee’s actions are not considered integrity violations. Taken to an extreme, delegating the right to undetectably change everything to everyone will achieve a property called contingency. Contingency was introd...

Projects require budgets to set the sponsor’s financial commitment and provide the basis for cost control and measurement of cost performance. A key component of a project budget is cost contingency.

To investigate the involvement of dopaminergic projections to the prelimbic and infralimbic cortex in the control of goal-directed responses, a first experiment examined the effect of pretraining 6-OHDA lesions of these cortices. We used outcome devaluation and contingency degradation procedures to separately assess the representation of the outcome as a goal or the encoding of the contingency ...

Although practitioners have begun to implement Green IT into their companies, the governance of Green IT varies significantly. No research has been done to explain these differences in Green IT governance. Building upon contingency theory and IT governance, we develop a contingency model for Green IT governance which demonstrates the fit between contingencies and the company-specific configurat...
