Six experiments were used to examine the effects of explicit response, stimulus, and temporal dependencies on responding in an interfood interval. The first two experiments demonstrated that 10-segment 60-s interfood clocks controlled similar distributions of key pecking in pigeons regardless of whether response-reinforcement contiguity was required, allowed, or precluded. The third and fourth ...

The joint analysis of various ordinal variables is necessary in many experimental studies within research fields such as sociology and psychology. Therefore, the measures multiple dependence must be easy to interpret facilitate interpretation multivariate models that fit data. main objective this article propose a correlation measure based on bivariate measure: Kendall’s tau. A sample version p...

Identify Data dependency between the attributes of a database play very important role in the design of normalization. Data dependency identifies value of attributes which are uniquely determine form some other attributes. Identify data dependency is useful for handling large relational database efficiently. Data dependency also helps for a database designer to split a large relational table in...

Among the variety of proposals currently making the dependency perspective on grammar more concrete, there are several treebanks whose annotation exploits some form of Relational Structure that we can consider a generalization of the fundamental idea of dependency at various degrees and with reference to different types of linguistic knowledge. The paper describes the Relational Structure as th...
