On finitely subadditive outer measures and modularity properties
Charles Traina
International Journal of Mathematics and Mathematical Sciences , 2003, DOI: 10.1155/s0161171203208115
Abstract: Let ν be a finite, finitely subadditive outer measure onP(X). Define ρ (E)=ν (X)−ν (E′) for E⊂X. The measurable sets Sν and Sρ and the set S={E⊂X/ν (E)=ρ (E)} are investigated in general, and in thepresence of regularity or modularity assumptions on ν. This is also done for ν0(E)=inf{ν (M)/E⊂M∈Sν }. General properties of ν are derived when ν isweakly submodular. Applications and numerous examples are given.

Charles Traina
International Journal of Mathematics and Mathematical Sciences , 2008, DOI: 10.1155/2008/896480
Abstract: Given a nonempty abstract set , and a covering class , and a finite, finitely subadditive outer measure , we construct an outer measure and investigate conditions for to be submodular. We then consider several other set functions associated with and obtain conditions for equality of these functions on the lattice generated by . Lastly, we describe a construction of a finite, finitely subadditive outer measure given an arbitrary family of subsets, ?, of and a nonnegative, finite set function defined on ?.

Abstract: ate on critical evidence for use of carnitine analogs in clinical practice in CNS disorders Review (3594) Total Article Views Authors: Traina G Published Date April 2011 Volume 2011:3 Pages 77 - 87 DOI: http://dx.doi.org/10.2147/NDS.S7119 Giovanna Traina Department of Economics and Food Sciences, University of Perugia, Perugia, Italy Abstract: L-carnitine (LC) is part of the carnitine shuttle system at the mitochondrial inner membrane (MIM) and transports long chain fatty acids over the MIM route. Acetyl-L -carnitine (ALC), the acetyl ester of LC, plays an essential role in intermediary metabolism. To ALC are ascribed neurotrophic actions, antioxidant and antiapoptotic activity, positive effects on mitochondrial metabolism, and stabilization of intracellular membranes. Acylcarnitine and LC supplementation have shown beneficial effects in the treatment of aging, chronic degenerative pathologies and the slowing of the progression of mental deterioration in neurodegenerative diseases, and painful neuropathies. ALC is reported to affect brain energy and phospholipid metabolism and to interact with cell membranes, proteins, and enzymes. It also shows a neuromodulatory effect on synaptic morphology and neurotransmitter synaptic transmission, including that of acetylcholine and dopamine. All these data suggest that ALC can affect several targets in the central nervous system. The roles and effects of LC and ALC have led researchers to investigate carnitine's involvement in a variety of neuropathological states and treatments, including autism, Parkinson's disease, Alzheimer's disease, Down's syndrome, Huntington's disease, cerebellar ataxia, age-associated mental decline, hepatic encephalopathy, and ammonia neurotoxicity. This review summarizes evidence that carnitine analogs play many roles in serious neurological pathologies.
Letteralita’ e metafora: dinamiche e costruzione a partire dalle riflessioni di Francois Recanati
Francesca Traina
Rivista Italiana di Filosofia del Linguaggio , 2012,
Abstract: Following Recanati (2004) metaphor is not confined to the post-semantic uses of language, but it will instead be conceived as an output of the complex pragmatic processes that actually concur in the activation or, vice-versa, in the inhibition of the potential meanings of the single parts of utterance. On the one hand, Recanati does not leave any doubt explaining the way pragmatic mechanisms determine figurative meanings; on the other hand, he is not explicit in clarifying what really happens in the language unit contributing to these mechanisms. In this paper, I will try to argue that Recanati always preserves the notion of literality of language units and will try to clarify the deep connection that relates terms’ semantic field to world’s knowledge
Outer measures associated with lattice measures and their application
Charles Traina
International Journal of Mathematics and Mathematical Sciences , 1995, DOI: 10.1155/s0161171295000937
Abstract: Consider a set X and a lattice ¢ ’ of subsets of X such that , X ¢ ¢ ’. M( ¢ ’) denotes those bounded finitely additive measures on A( ¢ ’) which are studied, and I( ¢ ’) denotes those elements of M( ¢ ’) which are 0 ¢ ’1 valued. Associated with a ¢ M( ¢ ’) or a ¢ M ( ¢ ’) (the elements of M( ¢ ’) which are -smooth on ¢ ’) are outer measures ¢ € 2 and ¢ € 3. In terms of these outer measures various regularity properties of can be introduced, and the interplay between regularity, smoothness, and measurability is investigated for both the 0 ¢ ’1 valued case and the more general case. Certain results for the special case carry over readily to the more general case or with at most a regularity assumption on ¢ € 2 or ¢ € 3, while others do not. Also, in the special case of 0 ¢ ’1 valued measures more refined notions of regularity can be introduced which have no immediate analogues in the general case.
Smoothness conditions on measures using Wallman spaces
Charles Traina
International Journal of Mathematics and Mathematical Sciences , 1999, DOI: 10.1155/s0161171299227135
Abstract: In this paper, X denotes an arbitrary nonempty set, ¢ ’ a lattice of subsets of X with ¢ …,X ¢ ¢ ’,A( ¢ ’) is the algebra generated by ¢ ’ and M( ¢ ’) is the set of nontrivial, finite, and finitely additive measures on A( ¢ ’), and MR( ¢ ’) is the set of elements of M( ¢ ’) which are ¢ ’-regular. It is well known that any ¢ M( ¢ ’) induces a finitely additive measure ˉ on an associated Wallman space. Whenever ¢ MR( ¢ ’), ˉ is countably additive.

From Crimea to Syria. Re-defining the alleged historical earthquake of 63 B.C.
G. Traina
Annals of Geophysics , 1995, DOI: 10.4401/ag-4068
Abstract: Within the SGA research on the historical seismicity of the Crimean Peninsula (SGA Report, 1990), interest has been focused on the case of the earthquake of 63 B.C. According to regional seismic catalogues as well as to historic and archaeological literature, two late Roman sources. Dio Cassius and Paulus Orosius, allegedly give evidence of an earthquake which happened in the Crimea in this year; the event was linked to the death of Mithridates V1 Eupator, eventually the king of Pontos. Local archaeologists claimed to have found evidence of this event in the excavations of Panticapaeunl (present-day Ker?). In fact. this is the result of a restricted analysis of the written sources. Thence stems a sort of iivulgatan. currently accepted by scholarship, yet not really supported by the evidence. A re-examination of the whole question, including an analysis of all sources avalaible on earthquakes in the Eastern Mediterranean. showed that in that period no seismic event took place in the Crimea. Dio's and Orosius' accounts are instead concerned with another earthquake, already known for Syria from other sources. This historical case gives a proper methodological example of the problems concerned with the analysis of the evidence in historical seismology. not only of Antiquity, but of almost any premodern period.

Implementing a Service of Independent Living Using a Participatory Approach  [PDF]
Ivan Traina
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102591
Abstract: This paper presents a case study about the implementation of a service of independent living using a participatory approach. The service promoted living experiences in apartments with innovative activities, characterized by means for the development of personal autonomy addressed to persons with disabilities and older persons. The paper shows the methodology applied, the experimentation process and the lessons learnt from the experience. Realized in the framework of the doctoral thesis titled “Social inclusion of vulnerable groups through participatory and emancipatory approaches. Implementing active citizenship and socially innovative actions in the framework of civil & human rights model of disability”. The implementation of the service has allowed demonstrating the initial research hypothesis according to which “an open participation in the co-creation of a service makes life easier for vulnerable groups”, gaining more knowledge about how to involve vulnerable groups as co-creators of services. This aspect can support the shift from situations based only on medical approach (passive situation), towards ones based on human rights (active situation). Placing the person with her/his needs, desires, objectives and expectations at the centre of actions and interventions.
