Journal Guide

Oikos is a journal issued by the Nordic Ecological Society and is one of the leading peer-reviewed journals in ecology. Oikos publishes original and innovative research on all aspects of ecology. Emphasis is on theoretical and empirical work aimed at generalization and synthesis across taxa, systems and ecological disciplines. Papers should be well founded in ecological theory and contribute to new developments in ecology by reporting novel theory or critical experimental results. Confirming or extending the established literature is given less priority. Synthesis of new and emerging fields in ecology and beyond is encouraged. Papers of review character should strive for conceptual unification and being a point of departure for future work rather than restrospective summaries of established fields or topics. Papers in Brevia, Horizons and Forum sections are given high priority in the publication process. Oikos Sections Research papers - Research papers report original research in all fields of ecology and should aim at a readership from a wide range of ecological disciplines. Research papers' manuscripts should have a maximum of 50 references. Forum - Forum is the section in Oikos where syntheses and reviews are published. The format can be short notes or more substantial reviews aimed at bringing fields together, to transgress existing boundaries and to syntesize larger fields or seemingly disparate areas, and to offer new ways of interpreting existing data. Forum articles should strive for conceptual unification and being a point of departure for future work rather than just summarizing existing bodies of theory and data. It is an arena for challenging current thinking on ecological issues by revising established concepts and received knowledge through critical experiments or new theory so that new ground can be broken. Horizons - Horizons papers are short (maximum two printed pages) essays on the past and the future of ecological research, an exploration of new territories of ecology by a more speculative, yet scientifically sound, reasoning on topics that also may be more peripheral to traditional ecological thinking. Manuscripts are judged strongly on their novelty and originality.The Horizons section invites authors to look ahead, to go beyond the contemporary and mainstream and serves as an arena for informed reflections and outlooks within or outside the field of ecology. It is aimed at capturing emerging ideas and concepts by using existing knowledge and insights as a springboard for pointing in new directions and for breaking new grounds. Horizon articles may be solicited but are always sent out for review before possible publication. Brevia - Brevia offers the possibility to comment on and discuss papers published in Oikos. Brevia articles should be brief, succcinct and to the point and should broaden and widen the scope of published ccontributions, or debate controversial findings. It is open for discussions on fundamental issues in ecology or the way the science of ecology is done. Manuscripts should rarely be longer than approximately 5 pages with a very brief (maximum 200 words) opening summary and with a reference list in the standard Oikos format. Oikos does not publish book reviews. Oikos is published in cooperation with the journals Ecography, Lindbergia, J. Avian Biology, the internet journal Web Ecology and the monograph series Ecological Bulletins. Manuscripts may be transferred between these journals according to profile.

Optimal Control Applications & Methods provides a forum for papers on the full range of optimal and optimization based control theory and related control design methods. The aim is to encourage new developments in control theory and design methodologies that will lead to real advances in control applications. Papers are also encouraged on the development, comparison and testing of computational algorithms for solving optimal control and optimization problems. The scope also includes papers on optimal estimation and filtering methods which have control related applications. Finally, it will provide a focus for interesting optimal control design studies and report real applications experience covering problems in implementation and robustness. The subject involves the optimization of systems described by differential or difference equations and even covers hybrid systems and non-linear programming and optimization methods. The class of problems covered includes: static and dynamic optimization, linear-quadratic control, nonlinear optimal control, optimal systems design, dynamic programming, optimal stochastic control, periodic optimal control, optimal estimation, multi-criteria and multiple model optimal control, singular perturbation methods, repetitive control, the optimal control of large-scale or distributed systems, and time-delay systems. Papers on the theory of systems with great applications potential will be particularly encouraged including papers on areas such as predictive control, optimal adaptive control, nonlinear, safety critical and reliable control . There is a significant interest in applications, which includes: process and manufacturing, aerospace and defence, marine and automotive systems, structural and mechanical design, robotics and manufacturing systems, chemical, petrochemical and industrial processes, electric power generation and distribution systems, energy systems and management, operations research and business, socio-economic models, biological and biomedical systems, environmental control, water treatment and ecology management, electrical and electronic systems and health care and support. It also covers a wide range of interdisciplinary and complex systems problems, where multi-agent software solutions, intelligent sensors and either dynamic or static optimization plays a major role.

Oral Diseases is a multidisciplinary and international journal with a focus on head and neck disorders. This includes the basic sciences, well designed and controlled clinical research and analytical epidemiology. The essential requirement is that all research is hypothesis-driven. Equal emphasis will be placed on aetiology, pathogenesis, diagnosis, prevention and treatment. Oral Diseases publishes bimonthly.

Oral Science International, a journal of the Japanese Stomatological Society, publishes original articles describing basic and clinical research on the cellular and molecular characterization, prevention, diagnosis, and therapy of oral diseases as well as those that contribute to the advancement of stomatology and its related fields. Oral Science International will receive materials prepared and submitted according to these instructions. However, we reserve the right to make any changes necessary to make the contribution conform to the editorial standards of the Journal, as deemed by the Editorial Board based on the recommendations of the reviewers. Contributions can be made both by members and nonmembers of the Japanese Stomatological Society. Articles must deal with original research, case reports and reviews, not previously published or being considered for publication elsewhere.

Orbis Litterarum is an international journal devoted to the study of European, American and related literature. Orbis Litterarum publishes Peer reviewed, original articles on matters of general and comparative literature, genre and period, as well as analyses of specific works bearing on issues of literary theory and literary history. Orbis Litterarum: International Review of Literary Studies was founded in 1943 as a journal devoted to the study of literature in international and comparative perspectives. With a well consolidated global circulation Orbis Litterarum, edited at the University of Southern Denmark, has a distinguished publication record of original articles in English, German and French by scholars from all over the world on specific literary works as well as on more general aspects of literature. Not affiliated to any particular approach to literature or specialization and editorially independent of any private or public interests, Orbis Litterarum serves outstanding achievement in literary scholarship, criticism and theory.
