The Differential Effects of Minority State Ownership Types on the Internationalization of Emerging Market Multinationals from Democratic States

We argue that governments use different types of minority state ownership in domestic multinationals to balance the provision of public and private goods and maximize political survival in emerging market democracies. Using a sample of Brazilian multinationals, we combine instrumental and fixed-effects regressions with an in-depth case study in order to measure and describe the effects of two types of ownership ties. We show that ownership through state-controlled institutional investors has a positive effect on the internationalization level of multinationals, whereas the ownership by state agencies and state-owned enterprises shows an opposite effect. By looking at these effects from the perspective of the political survival of democratic rulers, we contrast our results against the empirical research on multinationals from authoritarian states.

Internationalization of peer reviewed and non-peer reviewed book publications in the Social Sciences and Humanities

In this article barycenters of the places of publication of monographs, edited books and book chapters are used to represent the internationalization of research in the Social Sciences and Humanities (SSH) as practiced at universities in Flanders (Belgium). Our findings indicate that, in terms of places of publication, the distance between peer reviewed and non-peer reviewed SSH book literature is growing. Whereas peer reviewed books are increasingly published abroad and in English, non-peer reviewed book literature remains firmly domestic and published in the Dutch language. This divergence is more the case for the Social Sciences than for the Humanities. For Law we have found a pattern along the lines of the Social Sciences. We discuss these findings in view of the two main readerships of SSH publications: international academia on the one hand, and a mostly domestic intelligentsia on the other.     

Internationalization of scientific journals: A measurement based on publication and citation scope

Although impact factor and related measurements are the best-known features of scientific journals, other characteristics are of particular interest. The way a journal reflects the internationalized nature of science may be determined by many methods, one of which is based on the distribution of authoring and citing countries. This can be systematically measured either by a comparison of these distributions with averages profiles of a discipline or specialty, or by concentration indexes on the other. This paper focuses on the first approach. As the average profile of science drifts with the level of visibility, stratification by impact level is discussed. In this study, experimental internationalization indexes were calculated on the SCI for journals belonging to Earth&Space and Applied Biology. Convergence of measurements (types of indexes, type of normalization, publication vs citation scope) is adressed. Internationalization indexes may have a variety of applications, including characterization of the scientific publishing market and sampling of the SCI for science indicators.     

The Role of Large Multinationals in the Dutch Technology Infrastructure. A Patent Citation Analysis

This paper investigates the impact of large multinational firms on the Dutch technology infrastructure. More specifically, it asks how the structure of the knowledge flows network matters for diffusion of technological knowledge in the Dutch economy. Patent citation analysis based on European Patent applications is used to quantify this network. The paper finds that there are large differences between firms in terms of the density of their 'ego-network', and the amount of knowledge spillovers to the Dutch economy that they generate.

A Transparent,Wearable Fluorescent Mouthguard for High-Sensitive Visualization and Accurate Localization of Hidden Dental Lesion Sites

Accurate detection and early diagnosis of oral diseases such as dental caries and periodontitis, can be potentially achieved by detecting the secretion of volatile sulfur compounds (VSCs) in oral cavities. Current diagnostic approaches for VSCs can detect the existence and concentrations, yet are not capable of locating the dental lesion sites. Herein, the development of a unique approach for accurately locating dental lesion sites using a fluorescent mouthguard consisting of the zinc oxide–poly(dimethylsiloxane) (ZnO-PDMS) nanocomposite to detect the local release of VSCs is reported. The ZnO-PDMS mouthguard displays a highly sensitive and selective response to VSCs, and exhibits high fluorescent stability, good biocompatibility, and low biological toxicity in normal physiological environments. Then, the wearable ZnO-PDMS mouthguard is demonstrated to be able to identify the precise locations of lesion sites in human subjects. Combined with image analysis, the mouthguards successfully uncover the precise locations of dental caries, allowing convenient screening of hidden dental lesion sites that are oftentimes omitted by dentists. Due to low cost, long-term stability, and good patient compliance, the proposed wearable mouthguard is suitable for large-scale production and enables widely applicable, preliminary yet accurate screening of dental lesions prior to dental clinics and routine physical examinations.     

Internationalization of communication a view on the evolution of scientific journals

Starting from a characterization of the level of internationalization of SCI journals, based on their authoring scope, the process of internationalization of scientific communication throughout the period 1981–97 is described. The growth of the classes of international journals at the expense of national-oriented ones, appears as a general trend in all disciplines. A kindred measure of internationalization at the country-level is proposed, based on the balance of country-authored publications between national-oriented and international-oriented journals. A typology of countries is sketched. The general trend towards internationalization is also clear at the country level. It can be generally interpreted as a positive evolution, with some exceptions as Russia in the recent period, where it appears together with the output decline, a counterpart of the disappearance of many journals from SCI. Some other examples of shocks with a covariation of internationalization and output are given. Country internationalization indexes also express the sensitivity of the country output indicators to the possible restriction of SCI sample to the international fraction. Considering evolutions of internationalization may be helpful for a comprehensive study of scientific long-term evolutions at the country level.
