Competition in international markets was traditionally the realm of large companies, with smaller firms tending to remain local or regional. Internationalisation was an expansion option of interest to some enterprises, but seldom was it a competitive necessity. Many opted to avoid the uncertainties of competing in foreign markets, and simply kept their firms small and local. Traditional internationalisation theories, therefore, focused mainly on large multinational corporations, and were less pertinent to smaller firms. With the liberalisation of trade, however, domestic firms are threatened by international competitors that are penetrating formerly protected markets. Nowadays, internationalisation affects everyone, whether or not they wish to internationalise themselves. The threats and opportunities of internationalisation must be addressed.Globalisation is transforming the competitive environment of small and large players alike. As a result, internationalisation issues will continue to be increasingly important to business. Public policy agendas already include programmes to help entrepreneurs become successful at internationalisation. There is a growing need to understand internationalisation in the context of entrepreneurship, as well as large multinationals.Knowledge of how, when and why firms internationalise - either incrementally or not - will surely be the focus of energetic researchers. Yet, up to now, academia has been lacking a journal dedicated to internationalisation issues. To fill this niche, the aforementioned editorial team wishes to offer an outlet for high-quality research addressing the opportunities and challenges intrinsic to internationalisation.The primary audience for this journal will be researchers of entrepreneurship and international business. In addition, readership is certain to include business-people and policy-makers.The editors invite submissions that analyse internationalisation, combining theore, tical and empirical work. Researchers will be encouraged to conduct comparative studies, and to evaluate competing theories. The composition of the editorial team - including experts in international business and experts in entrepreneurship - is designed to avoid editorial bias. Every effort will be made to reach a first decision about a submission, within sixty days. Officially cited as: J Int Entrep
Read free Language & Linguistics articles in the Routledge AAAL Collection. Find out more. The Journal of Quantitative Linguistics is an international forum for the publication and discussion of research on the quantitative characteristics of language and text in an exact mathematical form. This approach, which is of growing interest, opens up important and exciting theoretical perspectives, as well as solutions for a wide range of practical problems such as machine learning or statistical parsing, by introducing into linguistics the methods and models of advanced scientific disciplines such as the natural sciences, economics, and psychology. Specifically, JQL publishes on:Observations and descriptions of all aspects of language and text phenomena including the areas of psycholinguistics, sociolinguistics, dialectology, pragmatics, etc. as far as they use quantitative mathematical methods (probability theory, stochastic processes, differential and difference equations, fuzzy logics and set theory, function theory etc.), on all levels of linguistic analysis.Applications of methods, models, or findings from quantitative linguistics to problems of natural language processing, machine translation, language teaching, documentation and information retrieval.Methodological problems of linguistic measurement, model construction, sampling and test theory.Epistemological issues such as explanation of language and text phenomena, contributions to theory construction, systems theory, philosophy of science.

Pedagogy, Culture & Society is a fully-refereed international journal that seeks to provide an international forum for pedagogy discussion and debate. The identity of the journal is built on the belief that pedagogy debate has the following features: Pedagogy debate is not restricted by geographical boundaries: its participants are the international educational community and its proceedings appeal to a worldwide audience. Pedagogy debate is open and democratic: it is not the preserve of teachers, politicians, academics or administrators but requires open discussion. Pedagogy debate is eclectic and interdisciplinary: it draws on a wide range of different intellectual and practical traditions to clarify core problems and sustain deliberation. Pedagogy debate is concerned with the past, present and future: it involves thinking reflectively and critically about pedagogy policy and practice with the aid of organising concepts such as culture, politics and ideology. Pedagogy debate is culturally diverse: it involves communication between participants whose thinking is shaped by different cultural conditions ranging from the 8216;post-colonial' condition of many African and Asian countries to the 8216;post-centralised' condition of Eastern Europe and the 8216;post-modern' condition of Western liberal democracies.Peer Review Policy:All research articles in this journal have undergone rigorous peer-review, based on initial editor screening and anonymised refereeing by at least two anonymous referees.Disclaimer for Scientific, Technical and Social Science publications:Taylor & Francis and Pedagogy, Culture and Society make every effort to ensure the accuracy of all the information (the 8220;Content8221;) contained in its publications.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Articles are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches. Topical coverage includes: • Spectroscopy • Dynamics • Kinetics • Statistical mechanics • Thermodynamics • Electrochemistry • Catalysis • Surface science • Quantum mechanics • Quantum computing • Machine learning • Polymers and soft matter • Materials • Quantum Materials • Nanoscience • Energy • Surfaces/interfaces • Biophysical chemistry • Atmospheric Chemistry • Astrochemistry
Plant Science will publish in the minimum of time, research manuscripts as well as commissioned reviews and commentaries recommended by its referees in all areas of experimental plant biology with emphasis in the broad areas of genomics, proteomics, biochemistry (including enzymology), physiology, cell biology, development, genetics, functional plant breeding, systems biology and the interaction of plants with the environment.Manuscripts for full consideration should be written concisely and essentially as a final report. The main criterion for publication is that the manuscript must contain original and significant insights that lead to a better understanding of fundamental plant biology. Papers centering on plant cell culture should be of interest to a wide audience and methods employed result in a substantial improvement over existing established techniques and approaches. Methods papers are welcome only when the technique(s) described is novel or provides a major advancement of established protocols.Plant Science is not a publication vehicle for preliminary observations, for studies that are merely confirmatory of results accomplished in other plant systems, or that are addressed only to a specialized readership. Submitted manuscripts describing studies of preliminary nature, that are merely confirmatory in scope or of limited scope and interest to the general readership of the journal will be returned without formal review. As a general policy, the journal will no longer consider manuscripts just describing the cloning, sequencing and expression patterns of gene sequences that have been identified and characterized in other plant species, expression of a protein without proper characterization of the recombinant product and native form, the isolation, purification and characterization of enzymes extensively analyzed in other plants, description of molecular markers and plant genetic diversity without any relevant biological information, cell culture and/or transformation of plant species (or closely related species) already established in the literature and basic transcriptomic approaches with no further relevant functional characterization of genes of interest.
Schizophrenia Bulletin seeks to review recent developments and empirically based hypotheses regarding the etiology and treatment of schizophrenia. We view the field as broad and deep, and will publish new knowledge ranging from the molecular basis to social and cultural factors. We will give new emphasis to translational reports which simultaneously highlight basic neurobiological mechanisms and clinical manifestations. Much of the Bulletin content will be invited reviews and manuscripts organized as a theme by special guest editors. Also, the Bulletin will carry unsolicited manuscripts of high quality that report original data related to theme issues or where the Bulletin can provide a special venue for a major study.The editorial policy of the Schizophrenia Bulletin generally follows the Uniform Requirements guidelines articulated by the International Committee of Medical Journal Editors (http://www.icmje.org). The journal is published bi-monthly serving readership and contributors from the USA and internationally. Each issue of the Bulletin will be based on a major review and/or one or more themes comprised of 2-5 Reviews Articles covering clinical and basic scientific aspects of the theme area of the issue. Topics for future issues will be announced ahead of time and Original Reports related to the themes will be accepted for review. Some theme issues will be based on workshops and meeting symposia.We consider the Bulletin to be an ideal venue for special reports such as treatment guidelines or the presentation of translational science. The Bulletin will publish the proceedings and abstracts of the International Congress on Schizophrenia Research. The Bulletin will publish first person accounts, At Issue articles expressing opposing views on controversial scientific issues, succinct discourses on clinical and basic neuroscience concepts, and brief essays on the role of specific environmental and genetic factors in schizophrenia. The Schizophrenia Bulletin will continue the tradition of the front cover display of art from artists with mental illness.
Statistics & Probability Letters adopts a novel and highly innovative approach to the publication of research findings in statistics and probability. It features concise articles, rapid publication and broad coverage of the statistics and probability literature.Statistics & Probability Letters is a refereed journal. Articles will be limited to six journal pages (13 double-space typed pages) including references and figures. Apart from the six-page limitation, originality, quality and clarity will be the criteria for choosing the material to be published in Statistics & Probability Letters. Every attempt will be made to provide the first review of a submitted manuscript within three months of submission.The proliferation of literature and long publication delays have made it difficult for researchers and practitioners to keep up with new developments outside of, or even within, their specialization. The aim of Statistics & Probability Letters is to help to alleviate this problem. Concise communications (letters) allow readers to quickly and easily digest large amounts of material and to stay up-to-date with developments in all areas of statistics and probability.The mainstream of Letters will focus on new statistical methods, theoretical results, and innovative applications of statistics and probability to other scientific disciplines. Key results and central ideas must be presented in a clear and concise manner. These results may be part of a larger study that the author will submit at a later time as a full length paper to SPL or to another journal. Theory and methodology may be published with proofs omitted, or only sketched, but only if sufficient support material is provided so that the findings can be verified. Empirical and computational results that are of significant value will be published. We also plan to publish applications and case studies that demonstrate a novel use of existing techniques or have interesting innovative ideas about data collection, modelling or inference.
The journal covers a broad spectrum and brings together various disciplines,
for example, zoology, microbiology, molecular biology, genetics, mathematical
modelling, veterinary and human medicine. Multidisciplinary approaches and the
use of conventional and novel methods/methodologies (in the field and in the
laboratory) are crucial for deeper understanding of the natural processes and
human behaviour/activities that result in human or animal diseases and in economic
effects of ticks and tick-borne pathogens. Such understanding is essential for
management of tick populations and tick-borne diseases in an effective and environmentally
acceptable manner. The journal covers the following topics:
Ticks: biosystematics/taxonomy, morphology, evolution, ecology, physiology/biochemistry,
behaviour, molecular biology, genomics/proteomics, and control
Ecology/ecoepidemiology of tick-borne diseases: vector ticks and reservoir
hosts, the mechanisms and processes determining their abundance and distribution,
the occurrence and prevalence of pathogens in tick and tick-host populations,
tick-host-pathogen interactions at the ecological level and their dependence
upon environmental factors, natural focality, and risk assessments of exposure
to ticks and the occurrence of tick-borne diseases
Tick-borne pathogens: viruses, bacteria, and parasites, their biology in
ticks and vertebrates, pathogen-tick and pathogen-host interactions on the molecular
and cellular levels, transmission, coinfection, genomics/proteomics, and biosystematics/taxonomy
Tick-borne diseases in domestic animals and wildlife: epidemiology, diagnosis,
immunology, treatment, vaccination, control/management, and economics
Tick-borne human diseases: epidemiology, diagnosis, immunology, treatment,
vaccination, socioeconomics, and public health
In addition, methodological papers on all these areas will be published as well
as timely reviews on vectors and vector-borne diseases in which tick biology
or tick-borne diseases are addressed.
