The nearly Gorenstein property for numerical duplications and semitrivial extensions
2022
In this thesis we present and study the ideal duplication, a new construction within the class of the relative ideals of a numerical semigroup $S$, that, under specific assumptions, produces a relative ideal of the numerical duplication $SJoin^b E$, for some ideal $E$ of $S$. We prove that every relative ideal of the numerical duplication can be uniquely written as the ideal duplication of two relative ideals of $S$; this allows us to better understand how the basic operations of the class of the relative ideals of $SJoin^b E$ work. In particular, we characterize the ideals $E$ such that $SJoin^b E$ is nearly Gorenstein. With the aim to generalize this construction to commutative rings with…
Economic Logic with Internal Consistency (and Not Only Formal Rigour)
2022
As is well known, during his life Sraffa never published a work explicitly devoted to epistemological issues. This fact should not be interpreted to indicate Sraffa’s lack of interest in such concerns. From Sraffa’s unpublished manuscripts – kept at the Wren Library of Trinity College, Cambridge, and from the books of his personal library – we see that Sraffa had a strong interest in questions of philosophy of 8science (Kurz and Salvadori, 2005). Therefore, a reconstruction of Sraffa’s epistemological theory can only be conjectural and must not leave out of consideration his unpublished manuscripts. In a previous work (Salvadori and Signorino, 2007), we analysed a specific aspect of Sraffa’…
Explanations for use of dietary- and muscle enhancing dietary supplements among university students: a national cross-sectional study.
2022
Abstract Background Use of dietary supplements (DS) and muscle enhancing dietary supplements (MEDS) is frequent among students despite the lack of evidence of effects and health risks related to consumption. We need to increase our understanding of students’ motivation, examine potential gender differences, and explore explanatory factors, to address preventive measures related to use. Therefore, this study aimed to explore the frequency of, and the reasons for, DS use among university students, as well as explanatory factors for use of MEDS. Method Male and female students from nine Norwegian universities participated in this cross-sectional study. Participants responded to questions about…
