Drawing on Robinson’s cognition hypothesis, the study attempted to examine how task conditions influence EFL learners’ oral performance and whether learners’ individual differences in terms of tolerance of ambiguity and self-efficacy mediate the effects of such conditions. To this end, 62 Iranian intermediate EFL learners from private language institutes in Tehran performed four dyadic decision...

Gatekeeping procedures have been developed to solve multiplicity problems arising in clinical trials with hierarchical objectives where the null hypotheses that address these objectives are grouped into ordered families. A general method for constructing multistage parallel gatekeeping procedures was proposed by Dmitrienko et al. (2008). The objective of this paper is to study two related class...

The concept of multiplicity in UML derives from that of cardinality in entity-relationship modeling techniques. The UML documentation defines this concept but at the same time acknowledges some lack of obviousness in the specification of multiplicities for n-ary associations. This paper shows an ambiguity in the definition given by UML documentation and proposes a clarification to this definiti...

Purpose – The “fuzzy front end” of new product development (NPD) is characterized by considerable uncertainty and ambiguity, but detailed studies of ambiguity specifically related to NPD are missing. This paper aims to establish a classification of ambiguity in NPD processes. Design/methodology/approach – The authors’ research design is a holistic multiple-case-study design with the NPD project...

One of the stylistic features of Hafez’s sonnets is the repetition of a part of the meaning of the first line in the second line. His knowledge of the rhetorical and semantic relations of vocabularies enabled him to repeat the meaning with the least verbal repetition. One of the ways that has helped him to achieve this goal is replicating the concepts in two parts of the couplet based on rhetor...

In the presence of several objectives, goal conflict may be avoided via multifinal means, which advance all of the active goals at once. Because such means observe multiple constraints, they are fewer in number than the unconstrained means to a single goal. Five experimental studies investigated the process of choosing or generating such means for multiple goals. We found that the simultaneous ...
