    Steady-State Cracks in Viscoelastic Lattice Models

    Full text link
    We study the steady-state motion of mode III cracks propagating on a lattice exhibiting viscoelastic dynamics. The introduction of a Kelvin viscosity η\eta allows for a direct comparison between lattice results and continuum treatments. Utilizing both numerical and analytical (Wiener-Hopf) techniques, we explore this comparison as a function of the driving displacement Δ\Delta and the number of transverse sites NN. At any NN, the continuum theory misses the lattice-trapping phenomenon; this is well-known, but the introduction of η\eta introduces some new twists. More importantly, for large NN even at large Δ\Delta, the standard two-dimensional elastodynamics approach completely misses the η\eta-dependent velocity selection, as this selection disappears completely in the leading order naive continuum limit of the lattice problem.Comment: 27 pages, 8 figure

    Acceleration and Deceleration in the Internationalization Process of the Firm

    By adopting a processual and dynamic view on internationalization, we develop the concepts of acceleration and deceleration, providing analytical tools to enhance our understanding of the non-linearity and multidimensionality of internationalization. We argue that acceleration and deceleration are embedded in the internationalization process and are a consequence of the firm’s capability to absorb and integrate acquired knowledge, and to find and exploit opportunities. In addition, we advance the idea that changes in speed are further influenced by how the firm integrates and coordinates the resources it has deployed within and across various internationalization dimensions. Thus, it emerges that the overall evolution of commitment to internationalization is more complex than received theories tend to present; therefore, empirical studies should aim to include a wide set of international activities and processes embedded in time

    Societal-level versus individual-level predictions of ethical behavior: a 48-society study of collectivism and individualism

    Get PDF
    Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed

    The Differences in Values Between Managers of the European Founding Countries, the New Members and the Applicant Countries: Societal Orientation or Financial Orientation?

    No full text
    Advocates for a social Europe are worried that the accession of ex-Eastern Bloc countries into the European Community would lead European corporations to emphasize a financial orientation rather than a societal orientation. We examined this question in a study of the values orientations of 3,836 managers in 16 countries representing established EU, new EU, and candidate EU country groups. Within-Europe managerial values convergence was found in a relatively high openness to change and low self-enhancement values. However, we found divergent values such that managers in established EU countries were more self-transcendent and less conservative than their counterparts in new EU and candidate EU countries. Implications for the convergence of future values within the Europe region are discussed
