EURO AND WEB SERVICES IN CUSTOMER BEHAVIOUR

The removal of internal customs barriers, the introduction of Euro and the suppression of frontier controls (Schengen treaty), joined with the enlargement of number of Members from 15 up to 25 represent the most meaningful aspects of the integrating process between the Countries of European Union before the forthcoming European Constitution. The actual configuration of the Union still completed the initial plan of a “Common Market”, obtained introducing some complying elements in the course of time. The last step of this integrating process was represented by the adoption of a common currency that really transformed the Union area in a unique market. The adoption of a common currency represented the main care versus the integration process. The reason of this care is that it really represents the first step towards the giving up of some intrinsic privileges in the sovereignty of a State. These steps are (and will be) requisite for a full achievement of the European Union aims. Nevertheless, some recent national events showed how much that unconfessed fear was undoubtly well-grounded. A first unexpected effect of the introduction of Euro is the possibility to outline all the persistent differences between States in a more effective way. These differences enable also to identify the heterogeneous conditions of economic, political, social and cultural behavior of each Country. The increased effectiveness of Internet made this evaluation more simple, enabling to consider the whole virtual environment as an immediately reachable place to obtain information, services and goods from sources that are distributed in all over the world. The aim of this paper is to outline that the homogeneity of internal market of European Union is still not completed showing some specific examples. A further attempt is to identify some factors of persistence of the still existing differences between European Countries.

Internet diffusion vs. The crisis of the new economy

The diffusion of Internet in the world, both in terms of ''users" and "information supplyiers" is continously and constantly increasing. This market growth is based on a development that follows the usual behaviour of technological innovation diffusion (S-shaped logistic curve), so it is allowed to obtain reliable forecasts about the future market trend. Nevertheless, dispite the continous growth of the "target", the E-business seems to be in a crucial situation absolutely unpredictable since few moths ago, when viceversa looked as the main driving force of the "new economy" attacking the boundaries of the "global market". The objective of this paper is to analyse the potentialities of the growing market, through the the actual and forecasted number of users, and the condition of the general offer, in terms of typology and quality of the services supplied, trying to identify a reason for this crisis.

Selecting Near-Optimal Learners via Incremental Data Allocation

We study a novel machine learning (ML) problem setting of sequentially allocating small subsets of training data amongst a large set of classifiers. The goal is to select a classifier that will give near-optimal accuracy when trained on all data, while also minimizing the cost of misallocated samples. This is motivated by large modern datasets and ML toolkits with many combinations of learning algorithms and hyper-parameters. Inspired by the principle of "optimism under uncertainty," we propose an innovative strategy, Data Allocation using Upper Bounds (DAUB), which robustly achieves these objectives across a variety of real-world datasets. We further develop substantial theoretical support for DAUB in an idealized setting where the expected accuracy of a classifier trained on $n$ samples can be known exactly. Under these conditions we establish a rigorous sub-linear bound on the regret of the approach (in terms of misallocated data), as well as a rigorous bound on suboptimality of the selected classifier. Our accuracy estimates using real-world datasets only entail mild violations of the theoretical scenario, suggesting that the practical behavior of DAUB is likely to approach the idealized behavior.Comment: AAAI-2016: The Thirtieth AAAI Conference on Artificial Intelligenc

Pensions reforms, workforce ageing and firm-provided welfare

This paper investigates the impact of an exogenous increase in the legal retirement age on the firms’ propensity to provide welfare services voluntarily to their employees. To this purpose we exploit a unique dataset derived from the Employers and Employees Survey, conducted by the National Institute for Public Policies Analysis (Inapp) in 2015 on a large and representative sample of Italian firms. By referring to the existing sociological and economic literature we make the hypothesis that a sudden increase in the share of older workers may motivate the employers to establish welfare schemes as a way to cope with an ageing workforce. The results obtained from different regression models show that firms which, as a consequence of the Law 214/2011 (the so-called “Fornero pension reform”), were forced to give up previously planned hirings increased the probability of providing welfare services at the workplace. This result also holds if propensity score matching methods are used in order to control for sample selection issues

Potentialities and usage of Internet communications: A qualitative and quantitative overview.

Technological innovation is the main responsible of the phenomenon called Internet. This innovative use of the medium accomplishes those concepts and dreams of science fiction's authors. Nevertheless, the new potentialities supplied by this new medium have only partially been analysed until today. Our purpose is to define a qualitative schema to investigate the main usage of Internet potentialities, joined with a quantitative analysis in the main geographic areas paying a special attention to the national and EEC data. The first goal is pursued identifying the better usage of the medium done by some representitives of the main socio-economic categories. These representitives could be chosen in any geographic area and their performances will be investigated, compared and used to define an analysing schema. The second objective is obtained using the best so-called "search engines", since the main characteristic of a site is represented by it's accessibility. Moreover, some cross-section data will be provided to enhance some more meaningful insights.

Fixed and Mobile Phoning in Italian Regions

The telecommunication diffusion and it?s interaction with the socio-economic environment was analysed both in terms of introduction of new technologies in the market and their diffusion/substitution process with respect to former technologies. Nevertheless, the word ?innovation? should be referred to products in a more general sense, so avoiding limitations to technology but also keeping track of all those characterising elements of products inside the market. Due to a similar approach, should be considered as innovative a product even if it doesn?t contain technological components different with respect to pre-existing ones, but also if a former technology is sold using totally innovative formulas. This modified viewpoint requires a more flexible approach to the diffusion process. This approach can enhance the interest on studying those different answers adopted by different socio-economic environments, to analyse the characteristic elements enabling the identification of categories with similar behaviour.

Corte costituzionale, automatismi legislativi e bilanciamento in concreto: "giocando con le regole" a proposito di una recente sentenza in tema di perdita della potest\ue0 genitoriale e delitto di alterazione di stato.

L'articolo intende verificare se le linee evolutive del sindacato di ragionevolezza-uguaglianza di cui si spesso si serve il diritto penale possano fornire indizi significativi di un progressivo superamento di un modello di decisione giudiziale basato su generalizzazioni trincerate, a tutto vantaggio di una strategia decisionale di tipo particolaristico
