How do firms combine different internationalisation modes? A multivariate probit approach
No full textMost of the literature on the relationship between firm’s participation in international markets and firm heterogeneity focuses on export and foreign direct investment. This paper considers a wider range of forms of internationalisation that firms could combine into different patterns. With the purpose of analysing the selection of heterogeneous firms into different internationalisation patterns, we jointly model the decisions on the forms of internationalisation through a multivariate probit. This model allows us to avoid any a priori assumption about the firm’s behaviour. In this context we study the complementarity/substitutability relationships between forms of internationalisation. The results obtained show that: i) neglecting some forms could lead to an incomplete representation about the firm’s internationalisation strategy, ii) different firm’s characteristics influence the choice of internationalisation pattern, i.e. some types of firm are more prone to choosing one type of process over another, iii) complementarity between forms of internationalisation seems to be preferred over substitution, but some heterogeneity also arises in this context
The reconstruction of human memories between Art and Design in the small Lucanian towns on Matera hills.
No full textIn 1980 the devastating earthquake in Irpinia, caused a complete disruption of the everyday life order in small towns, leaving only fragments of memories standing that stagger in the minds of those who have suffered a loss. Hence, the desire to collect, pass on, and disseminate the memory of these places in the silence of these landscapes, imagining a possible cultural reconstruction, through artistic expressions of identity that endure over time
Antimicrobial resistance gene shuffling and a three-element mobilisation system in the monophasic Salmonella typhimurium strain ST1030
No full textIn this study we describe the genetic elements and the antimicrobial resistance units (RUs) harboured by the Salmonella Typhimurium monophasic variant 1,4,[5],12:i:- strain ST1030. Of the three identified RUs two were chromosomal, RU1 (IS26-blaTEM-1-IS26-strAB-sul2- IS26) and RU2 (IS26-tetR(B)-tetA(B)-ΔIS26), and one, RU3 (a sul3-associated class 1 integron with cassette array dfrA12-orfF-aadA2-cmlA1-aadA1), was embedded in a Tn21-derived element harboured by the conjugative I1 plasmid pST1030-1A. IS26 elements mediated the antimicrobial resistance gene (ARG) shuffling and this gave rise to pST1030-1A derivatives with different sets of ARGs. ST1030 also harboured two ColE1-like plasmids of which one, pST1030-2A, was mobilisable and the target of an intracellular translocation of the Tn21-derived element; the second (pST1030-3) was an orphan mob-associated oriT plasmid co-transferred with pST1030-1A and pST1030-2A. pST1030-2A and pST1030-3 also carried a parA gene and a type III restriction modification system, respectively. Overall analysis of our data reinforces the role played by IS26, Tn21-derived elements and non-conjugative plasmids in the spread of ARGs and supplies the first evidence, at least in Salmonella, for the identification of a natural isolate harbouring a three-element mobilisation system in the same cell

No full textRecurrence of ovarian endometrioma after laparoscopic excision
No full textOur purpose was to evaluate the recurrence rate after laparoscopic excision of ovarian endometrioma. Study Design: An unrandomized prospective clinical study was performed at 2 tertiary-care centers of 366 patients who had a minimum of 6 months of postoperative follow-up or 6 months after the suspension of medical therapy after laparoscopic ovarian endometrioma excision. Patients underwent clinical examination and vaginal ultrasonography 3, 6, and 12 months after surgery and subsequently at least once a year. We evaluated the cumulative recurrence rate of pain and clinical findings of ovarian endometrioma, the rate of repeated surgery, and the recovery of fertility
