RISULTATI RICERCA

In this paper the possibility to introduce high-powered incentive schemes in public organizations is analyzed taking into account the attempts to reform public service in Italy since Dlgs n. 29/93 until the most recent normative and contractual developments. A simple formal model of promotions is presented and is examined by introducing typical features of public employment such as pensions, lateral entry restrictions and job security. From this model it emerges that with a well-defined system of promotions it is possible to introduce high-powered incentives even when dismissal is not an issue and out-put is hard to measure. In this perspective the last part of the paper is concerned with "tournaments" as means to define promotions. It is pointed out what could be the advantages and the disadvantages of using tournaments in the public sector especially when public employees are risk-adverse as empirical evidence seems to confirm.

Il contributo esplora lo sviluppo delle traiettorie di carriera dei dottori di ricerca nelle Scien-ze Sociali e Umane, analizzandole da due punti di vista complementari: in primo luogo si analizzano gli elementi che possono influenzare la variabilità dell’intera carriera in termini di mobilità tra settori e tra Paesi, in secondo luogo vengono considerati i singoli step di car-riera e le determinanti che favoriscono il passaggio tra lavori diversi.

Individuals’ mobility needs are constantly increasing both in urban and in less-densely popu-lated areas. Private transport activities are intensifying, creating unsustainable environmental pressure and absorbing a too large amount of resources, forcing to social exclusion the popu-lation segments which cannot bear the cost of private transport. Car sharing has proven to be a viable solution to alleviate at least partially these problems. Many different business models are used to provide the service. Organizational and technical innovations have changed the market, opening the supply to new providers and serving segments of the latent demand which were not reached by the traditional operators. The role played by the decision marker to sup-port the development of this market in its various forms has been essential and will still be crit-ical in order to guide a smooth transition from the private use of traditional vehicles to the shared use of autonomous ones. The purpose of this paper is to shed light on these changing characteristics of the carsharing market with a special focus on the Italian context.

«La Carta de Logu d’Arborea è un corpus di norme scritto in sardo arborense, promulgato dalla giudicessa Eleonora alla fine del Trecento. Questo volume fornisce per la prima volta l’edizione critica della Carta tràdita dall'incunabolo, che vede la luce in una data imprecisata dell’ultimo ventennio del XV secolo e che tramanda una versione differente rispetto a quella attestata nell'unico manoscritto superstite. Oltre a fornire un indizio delle relazioni politico-culturali esistenti nella Sardegna medievale, la Carta è una fonte preziosa per la conoscenza della lingua sarda.»

Mapping critical and sensitive areas in the buffer zone of the W’s - Transfrontier Biosphere Reserve Within the Ecopas framework, which is an Eu environmental cooperation program, a critical and sensitive areas mapping has been developed in order to support the decision within the Rbt/W governance (Burkina Faso, Benin, Niger). The Rbt/W system equilibrium relays on both geographical interaction and distribution of critical areas located on the cross border of the three countries involved. If one of those collapses, a chain of critical events might take place with heavy consequences for other border areas, as well as within the W Park itself. Concerning monitoring and intervention strategy, Ecopas and its partners focus their actions in those crowded areas (environmental conflicts, land pressure, cattle migration, institutional crisis).
