Le forme del lavoro associato con particolare riguardo all'associazione in partecipazione

The thesis has three chapters. The first one focuses in general on the associated employment, trying to give a unitary perspective and to show the several readings given by scholars. In detail, the thesis underlines the peculiar features of the associated employment relationships. The following chapters deal with the contract of “associazione in partecipazione” labour intensive. In the second chapter, this contract is analysed as it was originally provided by the Civil Code, with references to the relevant jurisprudence. In the third chapter, the thesis stresses the most outstanding characteristics of the contract in recent years, analysing all the legislative reforms in the field (in particular article 86, par. 2, Decree n. 276 of 2003 and its consequences in terms of social contribution), trying to interpret them in the present context.

Strumenti e metodi per lo sviluppo prodotto di lenti oftalmiche

The recent introduction of free form NC machining in the ophthalmic field involved a full review of the former product development process both from the design and the manufacturing viewpoint. Aim of the present work is to investigate and to set up innovative methods and tools supporting the product development, particularly for lenses characterized by free form geometry, as e.g. progressive lenses. In the design stage, the research addressed geometric modeling of complex lens shapes and relevant analysis tools for the optical-geometrical characterization of the produced models. In the manufacturing stage, the main interest was focused on the set-up of the fabrication process, particularly on the NC machining process for which an integration CADCAM software was developed for the generation and the simulation of the machining cycle. The methodologies and tools made available by the present work are currently used in the development of new complex geometry product typologies as, e.g. progressive lenses.
