Price discrimination and market power in export markets: The case of the ceramic tile industry.
2005
This paper combines the pricing-to-market equation and the residual demand elasticity equation to measure the extent of competition in the export markets of ceramic tiles, which has been dominated by Italian and Spanish producers since the late eighties. The findings show that the tile exporters enjoyed substantial market power over the period 1988-1998, and limited evidence that the export market has become more competitive over time.
ANÁLISIS DE LA RELACIÓN ENTRE EL COMPROMISO EXPORTADOR Y LAS AYUDAS A LA INTERNACIONALIZACIÓN DE LAS EMPRESAS /
2004
Las empresas que están iniciando o desarrollando su internacionalización se enfrentan a una serie de problemas que por si mismas no siempre pueden resolver. Las entidades públicas y privadas que diseñan e implementan los programas de ayuda a la internacionalización deben hacerlo partiendo de la determinación de las necesidades de las empresas. Estas necesidades varían en función, entre otros factores, de la etapa en que se encuentre la empresas en su proceso de internacionalización. El objeto del presente artículo es intentar justificar y modelizar la relación entre las necesidades de ayuda a la internacionalización de las empresas y su compromiso exportador, y en segundo lugar hacer una ap…
Connecting temporal identity to mitosis: the regulation of Hunchback in Drosophila neuroblast lineages.
2006
Both in vertebrates and invertebrates, neural stem cells generate different cell types at different times during development. It has been suggested that this process depends on temporal identity transitions of neural progenitors, but the underlying mechanism has not been resolved, yet. Recently, Drosophila neuroblasts (NBs) have been shown to be an excellent model system to investigate this subject. Here, changes in temporal identity are regulated by sequential and transient expression of transcription factors in the NB, such as Hunchback (Hb) and Kruppel (Kr). The temporal expression profile is maintained in the progeny. Hb is expressed first and thus defines the earliest identity in a giv…
Physical and Genetic Interactions Link the Yeast Protein Zds1p with mRNA Nuclear Export
2005
Eukaryotic gene expression requires the export of mRNA from the nucleus to the cytoplasm. The DEAD box protein Dbp5p is an essential export factor conserved from yeast to man. A fraction of Dbp5p forms a complex with nucleoporins of the cytoplasmic filaments of the nuclear pore complex. Gfd1p was identified originally as a multicopy suppressor of the rat8-2 ts allele of DBP5. Here we reported that Dbp5p and Gfd1p interact with Zds1p, a protein previously identified as a multicopy suppressor in several yeast genetic screens. By using the two-hybrid system, we showed that Zds1p interacts in vivo with both Gfd1p and Dbp5p. In vitro binding experiments revealed that Gfd1p and Dbp5p bind directl…

Le misure pubbliche di sostegno all'internazionalizzazione delle imprese
2020
Il capitolo analizza gli strumenti di supporto pubblico all'internazionalizzazione delle imprese italiane. In particolare, si esamina il ruolo delle pubbliche amministrazioni e degli istituti nazionali di promozione e il loro supporto tecnico e finanziario in favore delle piccole e medie imprese. The chapter analyzes the public support to the internationalization process of Italian firms. It examines the role of public administrations and national promotional banks and their financial and technical support to small and medium-sized enterprises.
Karyopherin Msn5 is involved in a novel mechanism controlling the cellular level of cell cycle regulators Cln2 and Swi5
2019
ABSTRACT The yeast β-karyopherin Msn5 controls the SBF cell-cycle transcription factor, responsible for the periodic expression of CLN2 cyclin gene at G1/S, and the nuclear export of Cln2 protein. Here we show that Msn5 regulates Cln2 by an additional mechanism. Inactivation of Msn5 causes a severe reduction in the cellular content of Cln2. This occurs by a post-transcriptional mechanism, since CLN2 mRNA level is not importantly affected in asynchronous cultures. Cln2 stability is not significantly altered in msn5 cells and inactivation of Msn5 causes a reduction in protein level even when Cln2 is stabilized. Therefore, the reduced amount of Cln2 in msn5 cells is mainly due not to a higher …
Regulation of cell cycle transcription factor Swi5 by karyopherin Msn5
2012
AbstractInactivation of S. cerevisiae β-karyopherin Msn5 causes hypersensitivity to the overexpression of mitotic cyclin Clb2 and aggravates growth defects of many mutant strains in mitotic exit, suggesting a connection between Msn5 and mitotic exit. We determined that Msn5 controlled subcellular localization of the mitotic exit transcription factor Swi5, since it was required for Swi5 nuclear export. Msn5 physically interacted with the N-terminal end of Swi5. Inactivation of Msn5 caused a severe reduction in cellular levels of Swi5 protein. This effect occurred by a post-transcriptional mechanism, since SWI5 mRNA levels were not affected. The reduced amount of Swi5 in msn5 mutant cells was…
Translocation Biosensors – Cellular System Integrators to Dissect CRM1-Dependent Nuclear Export by Chemicogenomics
2009
Fluorescent protein biosensors are powerful cellular systems biology tools for dissecting the complexity of cellular processes with high spatial and temporal resolution. As regulated nucleo-cytoplasmic transport is crucial for the modulation of numerous (patho)physiological cellular responses, a detailed understanding of its molecular mechanism would open up novel options for a rational manipulation of the cell. In contrast to genetic approaches, we here established and employed high-content cellular translocation biosensors applicable for dissecting nuclear export by chemicogenomics. A431 cell lines, stably expressing a translocation biosensor composed of glutathione S-transferase, GFP and…
