The merger of populations, the incidence of marriages, and aggregate unhappiness
No full textLet a society's unhappiness be measured by the aggregate of the levels of relative deprivation of its members. When two societies of equal size, F and M, merge, unhappiness in the merged society is shown to be higher than the sum of the levels of unhappiness in the constituent societies when apart; merger alone increases unhappiness. But when societies F and M merge and marriages are formed such that the number of households in the merged society is equal to the number of individuals in one of the constituent societies, unhappiness in the merged society is shown to be lower than the aggregate unhappiness in the two constituent societies when apart. This result obtains regardless of which individuals from one society form households with which individuals from the other, and even when the marriages have not (or not yet) led to income gains to the married couples from increased efficiency, scale economies, and the like. While there are various psychological reasons for people to become happier when they get married as opposed to staying single, the very formation of households reduces social distress even before any other happiness-generating factors kick in. --Merger of populations,Integration of societies,Unhappiness,Marriages,Relative Deprivation
The application of byproducts legislation in Italy as a strategic lever for the competitiveness of businesses: an evolving legal administrative scenario
No full textIn 2018 the Italian production of special waste amounted approximately to 143.5 Mt with an increase of 3.3% if compared to 2017 and disposal costs in the range of 160-240 €/ton, practically doubled within the last years. Many companies have therefore experienced increasing difficulties in waste managing because of both the increase in disposal costs and the collection timing required by sector operators. In order to make the production residues a new resource for other production activities, it is possible to qualify and manage the residues as by-products by creating paths of industrial symbiosis. Industrial symbiosis allows the transfer of resources (such as by-products and waste but also services and expertise) between two or more dissimilar industries and it represents a key to reduce their annual management costs achieving as well greater competitiveness. In addition to these advantages, there are environmental and social benefits that can have positive impacts not only on the individual companies involved but also on a territorial scale. The economic advantages can be more relevant where the industrial symbiosis approach takes place in a systematic way, against a specific project, allowing to obtain economic margins from the transfer of resources from one company to another. The main administrative legal instrument for the realization of industrial symbiosis is the by-product regulated in Italy by art. 184-bis of Legislative Decree 152/06 and subsequent amendments. Despite some steps forward to encourage and facilitate the use of by-products (Ministerial Decree of the Environment October 13, 2016, n.264, List of producers and users of by-products, List of by-products of the Emilia-Romagna Region), application difficulties persist in Italy, preventing a systematic and organic implementation of industrial symbiosis as a normal practice in the management of
industrial production residues. The purpose of this work is to carry out an examination of the regulatory and application landscape of industrial symbiosis in Italy with particular reference to the regulation of the by-product, identifying some possible tools and measures to overcome the difficulties highlighted and to favor the use as by-products of production residues that meet specific criteria as required by current legislation

The FM and PL Libraries Documentation
No full textBuilding complex SPMD code in an ecient and portable way is nowadays a challenge, especially when there is no uniformity of tools and libraries across platforms. The Fast Messages (FM) and the Portability Library (PL) where both designed to provide the basis of an abstract enough framework for C, so that problems can be coded and ported to any supported platform with no more than a few changes in the makeles and a recompilation. The FM library provides a message passing communications library built around the Berkeley Active Messages library. The PL library provides the primitives for host to node communication for problem initialization and results collection, as well as other miscellaneous and potentially non-portable primitives. This technical report contains the documentation for both libraries.Technical report LCSR-TR-25

Differences in the behavior of advanced glycation end products and advanced oxidation protein products in patients with allergic rhinitis.
No full textBACKGROUND: The presence of oxidative stress in patients with asthma is well
documented; however, the role of oxidative stress in allergic rhinitis has
received less attention, although it is likely to be similar to that observed in
patients with asthma. Advanced glycation end products (AGEs) and advanced
oxidation protein products (AOPPs) are compounds formed by the transformation of
macromolecules, including proteins, which can serve as densitometric markers of
oxidative stress and inflammation in several diseases.
OBJECTIVE: The aim of this study was to investigate the role of AGEs and AOPPs as
new markers of oxidative stress and inflammation in patients affected by allergic
rhinitis.
METHODS: AGE and AOPP levels were determined in the sera of 25 patients with
allergic rhinitis and 64 healthy controls. AGEs and AOPPs were detected using
spectrofluorimetry and spectrophotometry, respectively.
RESULTS: AGE levels in patients were significantly higher than those in controls
(P < .0001). These levels were not affected by the presence of asthma. No
statistically significant differences were found between AOPP levels in patients
or controls (P = .38).
CONCLUSIONS: Formation of AGEs and AOPPs may be accelerated in immunological and
respiratory disorders such as asthma. Depending on the marker evaluated, the
presence or absence of oxidative stress in allergic rhinitis is controversial. To
our knowledge, this is the first study showing the possible involvement of AGEs
in allergic rhinitis. The different behavior observed for these 2 biomarkers is
very likely due to the activation of specific related biochemical pathways (eg, the myeloperoxidase pathway) associated with the condition under study
