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.

Abstract
Despite connections and common traits between geopolitics and international business based on geography and location, literature on this matter is somewhat scarce. This chapter aims to contribute to this literature gap. Using the Russian Federation as a case study and by framing its geopolitical situation, it seeks to answer the following question: What is the importance of geopolitical factors in international location decisions? Applying a hybrid methodology which combines qualitative and quantitative analyses, the chapter concludes though Russia has an innately favorable geopolitical situation, its full potential is not being exploited, remaining latent and underutilized. Additionally, the pragmatic standing of Russia's foreign policy, the permanence of some structures recalling the USSR and the persistence of corruption, and an unsteady business environment place constraints on improving the open market and raises obstacles to FDI.

Abstract
This study investigates the impact of Technology Balance of Payments (TBP) on countries' international competitiveness. Using dynamic panel data estimations for 26 OECD countries over the period 2000-2017, the estimations unambiguously show that a TBP surpluses significantly foster countries' international competitiveness, regardless of how this latter is measured.

Abstract
The literature focusing on rural and urban entrepreneurship has so far overlooked the conditions in which different institutional contexts can affect firms' performance. The present study addressed this gap by investigating the extent to which institutional factors impact distinctively the performance of rural and urban newly created ventures. Based on data gathered through a direct questionnaire, we obtained 408 responses from newly created ventures located in Portuguese business incubators and science parks. Resorting to econometric binary (logit) models, we found that certain institutional factors, namely EU policy support, financial support from other sources than not banks, business advice for starting up/ ongoing activities, and collaboration to access new markets, are critical for new venture export performance, particularly those located in rural settings. To a larger extent than for urban, rural new venture economic-related performance positive and significantly depend on central government policy support, close relatives' role models, and technological support at the R&D collaboration level. Given the relevance of embeddedness-related factors in rural municipalities, public authorities should follow strategies that involve a growing connection between rural entrepreneurs and a variety of actors from industry, academia and the public and private sectors in order to foster newly created venture performance.

Abstract
In the last decade, a growing number of studies have addressed the ongoing debate about whether corruption "sands" or "greases" the wheels of business at the firm level. This study revisits this debate and proposes a comprehensive theoretical framework to test whether corruption harms or boosts firm performance, as well as the extent to which this relationship is mediated by the countries' institutional settings, the size and strategic behaviour of the firms, and market competition. Based on a sample of 21,250 firms located in 117 emerging and developing countries, and resorting to instrumental variable (IV) estimations, three main results were found: (a) regardless of the proxy used for corruption and firm performance, the former clearly harms the latter; (b) corruption "greases the wheels" of business for African firms but it "sands the wheels" for firms in Latin America, the Caribbean, Eastern Europe, Central Asia, and Southern Asia; and (c) the negative impact of corruption on performance is mitigated for larger and exporting firms.

Abstract
Film consumers are continuously online and active in various social platforms. This phenomenon has led over-the-top (OTT) providers - empowered by social computing technologies - to establish a social media presence and incorporate elements drawn from social media into their services. However, little is known about existing OTT interfaces and their key social features. This study sought to provide a structured categorisation of the most salient social media features of the best-known applications in the OTT video business. In addition, a new social content network model, Avids, was proposed to connect individuals socially through films. Avids reaches beyond more fixed, functionality-based approaches applied in the development of OTT video sites and focuses on components related to sociality. This approach ensures a unified system in which the overall social media setting is embedded in every functional area of the platform's architecture, thereby allowing applications to trigger and support social behaviours absent from traditional OTT providers. A purpose-built international online survey was administered to 479 film lovers to assess how Avids' main features compare with traditional OTT video providers. The questionnaire was based on the technology acceptance model. The results confirm the critical role of sociality in film viewing-related activities.
