Integration of migrants in Italy: A simple general and objective measure

Measuring migrants’ integration into host societies is a challenging task as, in general, measuring any social behavior and social phenomena. The task is affected by many specific problems related to the definition of the objective of study and the impact of subjective evaluations in the construction of an index. Our study aims to provide a measure of integration as much as possible general and objective. More in details, first, we consider some different general aspects of the integration problem related to migrants’ polarization, cultural diversification, social stability, integration in the labor market. Second, we aggregate them in a synthetic linear index, which is rather objective since the weights are computed by only considering the statistical properties of our dataset, i.e. choosing those weights that minimize the information loss in terms of data variances/co-variances.Migrations; migrants’ integration; regional index; principal component analysis

The impact of a massive migration flow on the regional population structure: The case of Italy

Low economic growth rates are a common problem in many developed countries in Europe. This paper aims to highlight the possible role of demographic factors. Problems of low growth may be exacerbated by an increase in dependency ratios. However, large-scale migrations have been shown to positively affect the age composition of a population. Focusing on Italy, we estimate the impact of migration on the working age population ratio, population size and gross domestic product. We also show that migration may affect the economic gap between the North and South, posing a new potential problem to policymakers.

Reaction to Uncertainty and Market Mechanism:Experimental Evidence

Abstract Much of the evidence supporting the Ellsberg's paradox comes from experiments on individual choice and judgement. In this study, we address the issue whether, in market experiments, there is a tendency for anomalous behaviour to disappear or to be reduced as a consequence of market experience and feedback. We empirically test the validity of this assumption by running an auction market for the sale of both risky and uncertain prospects. We compare bidding behaviour and prices in market-like settings with valuations obtained from individual pricing tasks. We conclude that, with the repetition of the market experience, there is a tendency for subjective expected utility to perform better. However, economists' general assumption that, in laboratory experiments, poor performance of SEU is due to the lack of financial incentives or to the lack of market-like settings is by no means supported by our data.

Automated Synthesis of SEU Tolerant Architectures from OO Descriptions

SEU faults are a well-known problem in aerospace environment but recently their relevance grew up also at ground level in commodity applications coupled, in this frame, with strong economic constraints in terms of costs reduction. On the other hand, latest hardware description languages and synthesis tools allow reducing the boundary between software and hardware domains making the high-level descriptions of hardware components very similar to software programs. Moving from these considerations, the present paper analyses the possibility of reusing Software Implemented Hardware Fault Tolerance (SIHFT) techniques, typically exploited in micro-processor based systems, to design SEU tolerant architectures. The main characteristics of SIHFT techniques have been examined as well as how they have to be modified to be compatible with the synthesis flow. A complete environment is provided to automate the design instrumentation using the proposed techniques, and to perform fault injection experiments both at behavioural and gate level. Preliminary results presented in this paper show the effectiveness of the approach in terms of reliability improvement and reduced design effort

Possible Implication of Red Blood Cells in the Prothrombotic Risk in Early Rheumatoid Arthritis

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that can be considered as a prothrombotic state1. A great number of studies have investigated the possible role of reactive oxygen species (ROS) in the etiology and pathogenesis of this disease. The presence of large amounts of superoxide radicals and hydrogen peroxide produced by activated neutrophils has been reported in the synovial fluid of patients with RA. This may cause lipid peroxidation that yields a wide variety of end products, including malondialdehyde (MDA), a known marker of oxidative stress. These products are therefore transported from the synovial fluid to the blood circulation system2. Considering that elevated levels of MDA have been observed in the blood plasma of patients with RA2, the aim of this pilot study was to investigate whether the elevated levels of plasmatic MDA could be associated with a modification of the total antioxidant capacity (TAC) of blood plasma that is usually indicative of a “systemic” oxidative imbalance3. In addition, in view of their activity as redox effectors or scavengers4, as well as determinants of thrombus formation5, we evaluated red blood cell (RBC) features in terms of their redox state and lifespan marker molecules
