Including income from (speculative) financial transactions will lead to instability if the amount is sufficiently large. Considering the present amount of financial transactions, stability is impossible. Therefore, further financial crashes are not only likely but inevitable.

The contribution presents some specific socio-economic features of this particular illness in contemporary Greece, emphasizing on some of the core strategies these diagnosed women apply in respect with their professional re-orientation. It as well analyses the inter-subjective experience of breast cancer in as much as participants record it as a turning point regarding their economic status, socio-psychological state, biographies and overall relationships. The paper is based both on qualitative research, grounded on fourteen biographical interviews with Greek women, experiencing breast cancer and mastectomy and on quantitative data provided by secondary inquiry. In an integrated view, it is possible to formulate some preliminary conceptual tools that can account for the economic dimensions and socio-psychological implications of the disease. Besides, we present the energetic strategies these women employ to mitigate personal suffering and transform their “harmed” body to an energetic source of professional re-orientations and biographical re-constitutions.

It contributes to the field of international business by providing hypotheses about organizational and owner-manager’s characteristics which affect SME internationalization. Combining the Resource-Based View and the Upper Echelons Theory the study creates a more complete picture of the effect of organizational and owner-manager’s characteristics on the likelihood of SME internationalization. The proposed hypotheses are tested in a sample of Bulgarian SMEs offering empirical evidence about SME internationalization in a transition context and addressing the call for more research in this context.
