Although they have developed very much in isolation from each other, we argue the theory of entrepreneurship and the economic theory of the firm are closely related, and each has much to learn from the other. In particular, the notion of entrepreneurship as judgment associated with Frank Knight and some Austrian school economists aligns naturally with the theory of the firm. In this perspective, the entrepreneur needs a firm, that is, a set of alienable assets he controls, to carry out his function. We further show how this notion of judgment adds to the key themes in the modern theory of the firm (i.e., the existence, boundaries, and internal organization). In our approach, resource uses are not data, but are created as entrepreneurs envision new ways of using assets to produce goods. The entrepreneur’s decision problem is aggravated by the fact that capital assets are heterogeneous. Asset ownership facilitates experimenting entrepreneurship: Acquiring a bundle of property rights is a low cost means of carrying out commercial experimentation. In this approach, the existence of the firm may be understood in terms of limits to the market for judgment relating to novel uses of heterogeneous assets; and the boundaries of the firm, as well as aspects of internal organization, may be understood as being responsive to entrepreneurial processes of experimentation. Key words: Entrepreneurship, heterogeneous assets, judgment, ownership, firm boundaries, internal organization. JEL Codes: B53, D23, L2

Las recidivas varicosas, posiblemente, son uno de los temas peor estudiados en nuestra especialidad, y desconocemos, en gran medida, la realidad de este tema. Tampoco existen suficientes consideraciones con respecto al tratamiento inicial que se ha empleado, ni a las causas patológicas que originan dichas recidivas. Esto, en gran parte, se debe a la dificultad en elaborar bases de datos amplias y, a largo plazo, en un grupo de población, generalmente joven, que, una vez operados, no suelen volver al médico ni por ellos mismos ni por nosotros, ya que ocuparían y consumirían una gran cantidad de recursos tanto directos, sanitarios, como indirectos, en pérdida de horas de trabajo. Sin embargo, hablamos de enfermedades crónicas, de amplia afectación social, que necesitan un control y, sobre todo, una prevención. Para ello, nosotros, los especialistas, deberíamos contar con unas ideas más homogéneas, así como de unas guías clínicas para aplicar en estos casos, que estuvieran en plena sintonía con la atención primaria.

Background/Objective: This study sought to assess the psychometric properties of the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) in patients with resected, non-metastatic cancer and eligible for adjuvant chemotherapy. Method: A total of 568 patients were recruited from a multi-institutional, prospective, transversal study. Patients answered the SDM-Q-9 after visiting their medical oncologist who, in turn, completed the SDM-Q-Physician version. Reliability, factorial structures [exploratory factor analysis (EFA), confirmatory factor analysis (CFA)], and convergent validity of the SDM-Q-9 scores were explored. Results: SDM-Q-9 showed a clear factorial structure, compatible with a strong and replicable general factor and a secondary group factor, in patients with resected, non-metastatic cancer. Total sum scores derived from the general factor showed good reliability in terms of omega coefficient: .90. The association between patient and physician perception of SDM was weak and failed to reach statistical significance. Males and patients over 60 years of age displayed the greatest satisfaction with SDM. Conclusions: SDM-Q-9 can aid in evaluating SDM from the cancer patients' perspective. SDM-Q-9 is helpful in studies examining patient perspectives of SDM and as an indicator of the degree of quality and satisfaction with health care and patient-physician relationship.

During the Middle Ages, rulers from different regions aspired to an idea of imperial hegemony. On the other hand, there were rulers who deliberately refused to be «emperors», although their reign showed characteristics of imperial rule. The contributions in this volume ask for the reasons why some rulers such as Charlemagne strove for imperial titles, whereas others voluntarily shrank from them. They also look at the characteristics of and rituals connected to imperial rule as well as to the way Medieval empires saw themselves. Thus, the authors in this volume adopt a transcultural perspective, covering Western, Eastern, Northern and Southern Europe, Byzantium and the Middle East. Furthermore, they go beyond the borders of Christianity by including various caliphates and Islamic «hegemonic» rulers like Saladin. Projektname: OGeSoMo
