International Business as disciplinary tautology: an ontological perspective

The identity, legitimacy, and sustainability of international business (IB) as a research field are at stake. IB is being overtaken by the evolution of industries and technology, and critical voices challenge its distinctiveness and value. We identify IB’s ambiguous conceptual space, articulate the roots of the problem, and suggest a perspective for re-legitimizing the discipline. Specifically, we contend that redrawing legitimate knowledge boundaries for IB requires an ontological shift. In this respect, we promote a focus on the processual constitution of international entities across time and a reconceptualization of IB as the amalgamation of local and international forces. The perspective we advocate aims to counterbalance the disciplinary tautology suffered by current IB conceptualizations and to open up the discussion on boundary identification in the field

Individual Entrepreneurship Capacity and Performance of SMEs

This paper analyses the importance of human capital and organizational capital on the determination of SME’s performance, by proposing and testing a conceptual model about Individual Entrepreneurship Capacity, and its impact both on non-economic and economic performance. This constitutes an innovative approach in the sense that uses information collected at the individual level, that is, the entrepreneur. Moreover, it constitutes a first attempt for facing the caveat in the literature on the relationship among types of capital and entrepreneurial performance. A model where the individual entrepreneurship capital is defined as a function of two types of capital: Human and Organizational; is proposed and empirically tested. For the Human Capital we consider three dimensions: (a) Individual Characteristics; (b) Managerial Push; and (c) Managerial Pull. As concerns the Organizational Capital, four dimensions are considered: (i) Individual Entrepreneurial Behavior; (ii) Collective Entrepreneurial Behavior; (iii) Managerial Practices; and (iv) Organizational Culture (in terms of the Superstructure and the Socio-Structure). The use of the stepwise method provides the selection of significant variables that impact on SME’s performance. When only non-economic indicators are considered for measuring the performance, in what respects the human capital we find out that the only significant variable is: enthusiasm at work. In what concerns the organizational capital the significant variables are: efficient organizational structure; participative management; incentives for interdisciplinary discussion and dialogue; and frequent meetings of working groups. For its turn, when economic indicators are considered for measuring the performance, we find out that the significant human capital determinants are: entrepreneur’s intuition; and propensity for innovating activities. In terms of organizational capital determinants we reveal that the significant variables are: efficient organizational structure; and use of external indicators for improving entrepreneurial performance. The main policy implication of the paper is the possibility of creating, at an individual level, new incentives and motivational tools based on the identification of the most important variables of human capital and organizational capital, for fostering SME’s performance

Defining family business: a closer look at definitional heterogeneity

Researchers have used a myriad of different definitions in seeking to explain the heterogeneity of family firms and their unique behavior; however, no widely-accepted definition exists today. Definitional clarity in any field is essential to provide (a) the basis for the analysis of performance both spatially and temporally and (b) the foundation upon which theories, frameworks and models are developed. We provide a comprehensive analysis of prior research and identify and classify 82 definitions of family business. We then review and evaluate five key theoretical perspectives in family business to identify how these have shaped and informed the definitions employed in the field and duly explain family firm heterogeneity. Finally, we provide a conceptual diagram to inform the choice of definition in different research settings

Stable isotope study of a new chondrichthyan fauna (Kimmeridgian, Porrentruy, Swiss Jura): An unusual freshwater-influenced isotopic composition for the hybodont shark Asteracanthus

Chondrichthyan teeth (sharks, rays, and chimaeras) are mineralized in isotopic equilibrium with the surrounding water, and parameters such as water temperature and salinity can be inferred from the oxygen isotopic composition (δ18Op) of their bioapatite. We analysed a new chondrichthyan assemblage, as well as teeth from bony fish (Pycnodontiformes). All specimens are from Kimmeridgian coastal marine deposits of the Swiss Jura (vicinity of Porrentruy, Ajoie district, NW Switzerland). While the overall faunal composition and the isotopic composition of bony fish are generally consistent with marine conditions, unusually low δ18Op values were measured for the hybodont shark Asteracanthus. These values are also lower compared to previously published data from older European Jurassic localities. Additional analyses on material from Solothurn (Kimmeridgian, NW Switzerland) also have comparable, low-18O isotopic compositions for Asteracanthus. The data are hence interpreted to represent a so far unique, freshwater-influenced isotopic composition for this shark that is classically considered a marine genus. While reproduction in freshwater or brackish realms is established for other hybodonts, a similar behaviour for \textit{Asteracanthus} is proposed here. Regular excursions into lower salinity waters can be linked to the age of the deposits and correspond to an ecological adaptation, most likely driven by the Kimmeridgian transgression and by the competition of the hybodont shark Asteracanthus with the rapidly diversifying neoselachians (modern sharks)

Supplementary material to Stable isotope study of a new chondrichthyan fauna (Kimmeridgian, Porrentruy, Swiss Jura): an unusual freshwater-influenced isotopic composition for the hybodont shark <i>Asteracanthus</i>"

Abstract. Chondrichthyan teeth (sharks, rays and chimaeras) are mineralised in isotopic equilibrium with the surrounding water, and parameters such as water temperature and salinity can be inferred from the oxygen isotopic composition (δ18Op) of their bioapatite. We analysed a new chondrichthyan assemblage, as well as teeth from bony fish (Pycnodontiformes). All specimens are from Kimmeridgian coastal marine deposits of the Swiss Jura (vicinity of Porrentruy, Ajoie district, NW Switzerland). While the overall faunal composition and the isotopic composition of bony fish are consistent with marine conditions, unusually low δ18Op values were measured for the hybodont shark Asteracanthus. These values are also lower compared to previously published data from older European Jurassic localities. Additional analyses on material from Solothurn (Kimmeridgian, NW Switzerland) also have comparable, low-18O isotopic compositions for Asteracanthus. The data are hence interpreted to represent a so far unique, freshwater-influenced isotopic composition for this shark that is classically considered as a marine genus. While reproduction in freshwater or brackish realms is established for other hybodonts, a similar behaviour for Asteracanthus is proposed here. Regular excursions into lower salinity waters can be linked to the age of the deposits and correspond to an ecological adaptation, most likely driven by the Kimmeridgian transgression and by the competition of the primitive shark Asteracanthus with the rapidly diversifying neoselachians (modern sharks). </jats:p
