There are many psychological tasks that involve the pairing of binary variables. The various tasks used often address different questions and are motivated by different theoretical issues and traditions. Upon closer examination, however, the tasks are remarkably similar in structure. In the present paper, we examine two such tasks, the contingency judgment task and the signal detection task, an...

A unified approach to power system security assessment and contingency analysis suitable for on-line applications is proposed. The severity of the contingency is measured by two scalar Performance Indices (PIs): Voltage-reactive power performance index, PIVQ and line MVA performance index, PIMVA. In this paper, a two stage cascade neural network is developed: Stage I employs Multi-Layer Percept...

Contingency analysis and reaction is a critical task to be carried out by any airplane to guarantee its safe operation in a non-segregated airspace. Pilot’s reactions to any kind of incidences that may occur in-flight, like engine malfunctions, loss of electrical power, hydraulic failure, unexpected weather, etc, will determine the fate of the flight. Nowadays, contingency reactions are mainly ...

The analysis of R×C contingency tables usually features a test for independence between row and column counts. Throughout the social sciences, the adequacy of the independence hypothesis is generally evaluated by the outcome of a classical p-value null-hypothesis significance test. Unfortunately, however, the classical p-value comes with a number of well-documented drawbacks. Here we outline an...

an explanatory survey was carried out in 2008 to investigate the relationship between entrepreneurial orientation (eo), environmental factors, human capital and organizational characteristics vs. entrepreneurial performance among entrepreneurial firms in iranian agricultural sector. data were obtained from a sample of 120 iranian agricultural establishments, using an interview-oriented question...

Although practitioners have begun to implement Green IT into their companies, the governance of sustainable information systems varies significantly. Only little 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 comp...

The item-specific proportion congruency (ISPC) effect is the finding of attenuated interference for mostly incongruent as compared to mostly congruent items. A debate in the Stroop literature concerns the mechanisms underlying this effect. Noting a confound between proportion congruency and contingency, Schmidt and Besner (2008) suggested that ISPC effects are entirely contingency based. We int...
