Verso una didattica linguistica riflessiva. Percorsi di formazione iniziale per insegnanti di italiano lingua non materna
2014
italiano Nato dall’esigenza di fare il punto sull’esperienza del Master in “Teoria, progettazione e didattica dell’italiano come lingua seconda e straniera” dell’Università di Palermo, giunto ormai alla sesta edizione, il volume intende gettare le basi di ulteriori itinerari di ricerca e riflessione sulla didattica dell’italiano come lingua non materna. È destinato a chi è interessato al Master come apprendente o a chi voglia confrontarsi con le esperienze messe a punto a Palermo e con le opzioni che le fondano: sul piano scientifico, l’interconnessione stretta fra competenza didattica e competenza linguistica come finalità formativa e, sul piano didattico, l’approccio riflessivo alla forma…
Networks of knowledge among unionized firms
2008
We develop a model of strategic networks in order to analyze how trade unions will affect the stability of R&D networks through which knowledge is transmitted in an oligopolistic industry. Whenever firms settle wages, the partially connected network is likely to emerge in the long run if and only if knowledge spillovers are large enough. However, when unions settle wages, the complete network is the unique stable network. In other words, the stronger the union bargaining power is, the more symmetric stable R&D networks will be. In terms of network efficiency, the partially connected network (when firms settle wages) does not Pareto dominate the complete network (when unions settle wages) an…
Networks of manufacturers and retailers
2011
We study the endogenous formation of networks between manufacturers of differentiated goods and multi-product retailers who interact in a successive duopoly. Joint consent is needed to establish and/or maintain a costly link between a manufacturer and a retailer. We find that only three distribution networks are stable for particular values of the degree of product differentiation and link costs: (i) the non-exclusive distribution & non-exclusive dealing network in which both retailers distribute both products is stable for intermediate degree of product differentiation and small link costs; (ii) the exclusive distribution & exclusive dealing network in which each retailer distributes a dif…
R&D networks among unionized firms
2005
We develop a model of strategic networks in order to analyze how trade unions will affect the stability and efficiency of R&D collaboration networks in an oligopolistic industry with three firms. Whenever firms settle wages, the complete network is always pairwise stable and the partially connected network is stable if and only if spillovers are large enough. If spillovers are small, the complete network is the efficient network; otherwise, the efficient network is the partially connected network. Thus, a conflict between stability and efficiency may occur: efficient networks are pairwise stable, but the reverse is not true. Strong stability even reinforces this conflict. However, once unio…
The dynamics of the financial capital – intellectual capital binomial relationship regarding the value creation process of a firm in the knowledge-ba…
2009
The idea that the value of the firm is given by its financial capital and its intellectual capital is generally accepted. But, what is changing nowadays is the importance/weight that each one of these two components claims to have regarding the value of the firm – based on the dynamics of the changes and the intensity of the competition within an industry, on one hand, and on the measure of connection/networking to the knowledge-based economy of the given industry, on the other hand. So, we are the witnesses of: (1) a repositioning into the dynamics of the financial capital – intellectual capital binomial relationship regarding the value creation process of a firm and (2) the need to reform…
Gestión empresarial y dinámica laboral en España
2015
El objetivo del presente artículo es plantear una serie de reflexiones sobre la dinámica labo- ral reciente en la economía española bajo el enfoque analítico de la segmentación laboral. Desde esta perspectiva, la situación y problemas del mercado laboral se explican por un conjunto de factores relacionados con las prácticas de gestión empresarial y no tanto por la regulación que limita la competencia en el mercado o las modalidades contractuales. Nues- tra conclusión es que es necesario superar el marco analítico restringido del enfoque econó- mico convencional e introducir otras dimensiones, que van más allá del mercado, para una mejor compresión de los problemas laborales. En este sentido…
Why Do European Venture Capital Companies Syndicate?
2002
Financial theory, resource-based theory and access to deal flow are used to explain syndication practices among European venture capital (VC) firms. The desire to share risk and increase portfolio diversification is a more important motive for syndication than the desire to access additional intangible resources or deal flow. Access to resources is, however, more important for non-lead than for lead investors. When resource-based motives are more important, the propensity to syndicate increases. Syndication intensity is higher for young VC firms and for VC firms, specialised in a specific investment stage. Finally, syndication strategies are similar across European countries, but differ fro…
Gouvernance contractuelle et cognitive des alliances internationales en R&D
2009
Notre objectif est d’expliquer le choix des firmes multinationales entre les alliances avec prise de participation et les alliances sans prise de participation pour investir en R&D à l’étranger. Les déterminants du choix peuvent être contractuels ou cognitifs. Nos résultats montrent que les alliances sans prise de participation sont choisies en cas d’une spécificité des actifs et de fréquence moyennes ou faibles des transactions et au cas où les firmes parentes détiennent des capacités en R&D similaires. Nos résultats montrent aussi que les firmes multinationales n’optent pas nécessairement pour les alliances à fort degré d’interdépendance organisationnelle dans un objectif d’exploration de…
Identifying a supply-chain related to the use of renewable natural resource: Case studies from France and Aquitaine region
2015
This paper aims to build a method to identify an economic sector. This type of method attempts to identify a pool of sub sector showing a strong intensity of economic flows between them. In this study, we show the potential of input output models for this type of analysis. Two types of contributions have been done here. First we improve the sub sector selection. Then we improve the calculation of the « economic distance between sub sectors belonging to the same sector. These improvements are applied to identified the wood sector in France but also at the regional level of Aquitaine. The empirical results show the features of sectors can vary between France and regions, mainly because of reg…
L'incidence des LBO sur la politique d'investissement et la gestion opérationnelle des firmes acquises:le cas français
2002
Cet article étudie dans quelle mesure la politique d'investissement ainsi que la gestion opérationnelle des firmes françaises reprises dans le cadre d'un leveraged buy-out (LBO) peuvent expliquer la dégradation de leur surperformance après l'opération. L'étude empirique porte sur 132 LBO réalisés en France de 1989 à 1994. Les résultats obtenus montrent qu'on ne peut expliquer la réduction anormale de la rentabilité économique de ces firmes par un effet mécanique imputable à des surinvestissements, ni par une dérive de la gestion de leurs actifs et passifs d'exploitation. En revanche, l'augmentation des frais de personnels ainsi que des consommations intermédiaires et/ou des réductions de pr…
