It has been observed in previous work that it is desirable to avoid causal violations in any execution or transformation of a parallel program. In this paper, we formalize the notion of causality in memory consistency models and code transformations. For memory models, we introduce a framework of causality graph that can be used to analyze if a particular memory model violates causality. We sho...

This paper focuses on the causality relation between US and the several Asia-pacific markets (Japan, China, Hong Kong, Taiwan, Singapore, Korea, and Indonesia). We check the causality of the co-movement among the markets across Pacific by using Granger-Causality test, VAR, and event studying on unexpected high volatile period. Our tests show that U.S. and Japan have strong influence to other As...

The results achieved in this research show that there are three long-run relationships between production, trade openness, energy consumption and carbon dioxide emissions. The EKC hypothesis was not ...

The Java Memory Model (JMM) formalizes the behavior of shared memory accesses in a multithreaded Java program. Dependencies between memory accesses are acyclic, as defined by the JMM causality requirements. We study the problem of post-mortem verification of these requirements and prove that the task is NP-complete. We then argue that in some cases the task may be simplified by tracing the actu...

Philosophers have long argued that causality cannot be directly observed but requires a conscious inference (Hume, 1967). Albert Michotte however developed numerous visual phenomena in which people seemed to perceive causality akin to primary visual properties like colour or motion (Michotte, 1946). Michotte claimed that the perception of causality did not require a conscious, deliberate infere...

This study re-examines the long run relationship between the budget and current account deficits in an oil-dependent open economy like Nigeria using a multivariate Granger causality test within the VECM framework. This result confirmed the existence of a long run relationship between the budget and current account deficit in Nigeria, thus supporting the Mudell-Fleming theory and refuting the Ri...
