and Orlicz spaces X Φ obtained by replacing the space L 1 in the classical construction by an arbitrary Banach function space X. Our main aim is to focus on the task to study inequalities in such spaces. We prove a number of new inequalities and also natural generalizations of some classical ones (e.g., Minkowski’s, H�lder’s and Young’s inequalities). Moreover, a number of other basic facts for further study of inequalities and function spaces are included.

Abstract  

We present an equivalence theorem, which includes all known characterizations of the class B p, i.e., the weight class of Ariño and Muckenhoupt, and also some new equivalent characterizations. We also give equivalent characterizations for the classes B p *, B * and RB p, and prove and apply a “gluing lemma” of independent interest.

Abstract  

Many new journals are started in response to increasing specialization and limited space in existing journals. In this study two journals in organization research are studied,Administrative Science Quarterly as the first mover in the field andOrganization Studies as the challenger. It is shown that the new journal gradually differ from the old in terms of the national origin of its authors as well as the documents cited. It is concluded that the scientific journal market may not mirror the copy-cat behaviour found among newspapers or companies in other markets.
