Abstract
The present study surveys and maps the existing methodological approaches for measuring creative employment. Based on a unique matched employer-employee data-set which encompasses over three million Portuguese workers, we found that the magnitude of the creative class varies considerably between approaches, ranging from 2.5%, using the conventional industry-based taxonomy and 30.8%, using Florida's occupational proposal. The disparities are justified on the basis of the departure definition of what creative employment is and operationalization issues regarding which industries and occupations should be included. Interestingly, when we focus on core creative employment, the figures conveyed by the distinct approaches are strikingly similar (around 6%), suggesting that, at least where core creative employment is concerned, the distinct approaches converge. The diversity of approaches and measurements are not necessarily a bad thing in itself, but has to be adequately acknowledged in order to accomplish adequate public-policy guidance.

Abstract
The advancement of knowledge on networks entails acknowledging the heterogeneity of their participants, more precisely, the organizations that lie beyond the scope of the activities of firms. Adopting a dynamic perspective of networks, and considering different types of innovation exchanges, we propose a hybrid and wider notion of industry which implies taking account of a set of local supporting organizations (LSOs) in domains such as research and technology, production factors, consultancy and training, and public support. Based on a rich data set built from face-to-face interviews with Portuguese automotive organizations, which resulted in a network comprising 867 organizations, we apply social network analysis techniques to analyse the structure, content and dynamics of the networks. The evidence gathered unveiled huge industry turbulence and significant changes in the boundaries of the Portuguese automotive networks over a 20-year period, with the emergence (and decline) of different prominent organizations. Specifically, following AutoEuropa major foreign direct investment (in 1995), the analyses reflect a clear increase in connectivity within the industry (from 524, before 1995, up to 2327 connections after 1995), with greater involvement among suppliers and between suppliers and LSOs, with the latter achieving top positions in the ranking of innovation networks.

Abstract
The speed of internationalization of firms has attracted considerable research in the last few decades. However, with regard to a particular type of firm, university spin-offs (USOs), this line of research is still incipient. A majority of the studies on USOs highlights their main features but does not focus on internationalization. Based on the responses from 111 Portuguese USOs, of which 78 are exporters, econometric estimations indicate that: (1) the internationalization speed of USOs is critically dependent on support from technology transfer offices; (2) in line with the “learning advantages of newness” perspective, younger Portuguese USOs reveal higher levels of entrepreneurial spirit and entrepreneurial capabilities, being in a better position to internationalize earlier than older USOs; (3) USOs that operate in microelectronics/robotics internationalize faster and earlier than USOs operating in ICT/software/digital media; and (4) in contrast with the literature on born globals/international new ventures, greater involvement in R&D activities slows down the early internationalization process of USOs. © 2014, Springer Science+Business Media New York.
