Physics is a journals dependent discipline . Our bottom line in shifting to electronic format is to increase usability ; if an electronic-only format makes a journal unusable , then we are more than willing to retain print . Modern Psychological Studies ( MPS ) is a journal devoted exclusively to publishing manuscripts by undergraduates . Poetry Review is a journal devoted exclusively to the criticism of poetry . The formulation of this impact measure , which comes from the work of Rasch , depends upon the difference in position of any two journals on the scale , and thus overcomes the problem of the ratio nature of the impact factor where a small number of both citations and source articles gives a journal equal or greater impact than one with a larger number of both . Ancient Narrative is a journal interested in the ancient Greek , Roman , and Jewish novelistic traditions as well as the reception of these traditions in modern literature , film and music .
