- Greenfield versus acquisition : the drivers for entry and expansion modes of German : based multinational enterprises in PortugalPublication . Langer, Tim Philipp; Reis, RicardoThis paper examines the determinants for entry and expansion modes of German multinational enterprises in Portugal. Using a sample of Greenfield and acquisition transactions from 1996 until 2013, we investigate the impact of previously proven parent-level and industry-level drivers that derive from Transaction Cost/Internationalization Theory, Information Economics and Industrial Organization Perspective, and further factors that may have had an influence on the decision to invest in Portugal. We find evidence that the parent’s size, its R&D intensity, the previous experience by another German firm, the target industry's growth and Portugal's membership in the Eurozone increase the probability of a Greenfield investment rather than an acquisition. In turn, the likelihood of an acquisition increases when the parent is publicly traded and productivity in the target industry grows. Our findings confirm that traditional theories can be applied to the particular combination of home and host country. Furthermore, specific policy recommendations can be given based on the results in order to promote German foreign direct investments in Portugal.

- Selection of potential probiotic enterococcus faecium isolated from Portuguese fermented foodPublication . Barbosa, Joana; Borges, Sandra; Teixeira, PaulaFour Enterococcus faecium strains isolated from fermented products were evaluated for potential use as probiotic strains. In addition to efaAfm gene, commonly found in E. faecium food isolates, none of the isolates possessed virulence genes and none had positive reactions for the production of tyramine, histamine, putrescine and cadaverine in the screening medium used. All of these four isolates proved to be resistant to 65. °C. E. faecium 119 did not show antimicrobial activity against any of the target bacteria investigated. E. faecium 85 and 101 inhibited Listeria innocua and E. faecium DSMZ 13590. The strain E. faecium 120 inhibited seven target bacteria (Listeria monocytogenes 7946, L. monocytogenes 7947, L. innocua 2030c, L. innocua NCTC 11286, E. faecium DSMZ 13590, Enterococcus faecalis ATCC 29212 and Staphylococcus aureus ATCC 29213) and was chosen as the representative to assess the ability to survive gastrointestinal tract passage simulation, as well as the protective role of two food matrices (skim milk and Alheira) during its passage. For both matrices used, no significant differences (p< 0.05) were obtained between the types of digestion - quick and slow passage simulation. In the skim milk matrix the isolate was reduced to values below the detection limit of the enumeration technique by the end of the two digestions, in contrast to the Alheira matrix, for which isolate 120 showed a reduction of only ca. 1. log. CFU/ml. The E. faecium strain 120 was shown to be a potential candidate for further investigations as a potential probiotic culture.
