The index theorem on the lattice with improved fermion actions

1998

We consider a Wilson-Dirac operator with improved chiral properties. We show that, for arbitrarily rough gauge fields, it satisfies the index theorem if we identify the zero modes with the small real eigenvalues of the fermion operator and use the geometrical definition of topological charge. This is also confirmed in a numerical study of the quenched Schwinger model. These results suggest that integer definitions of the topological charge based on counting real modes of the Wilson operator are equivalent to the geometrical definition. The problem of exceptional configurations and the sign problem in simulations with an odd number of dynamical Wilson fermions are briefly discussed. We consi…

Morse-Smale index theorems for elliptic boundary deformation problems.

2012

AbstractMorse-type index theorems for self-adjoint elliptic second order boundary value problems arise as the second variation of an energy functional corresponding to some variational problem. The celebrated Morse index theorem establishes a precise relation between the Morse index of a geodesic (as critical point of the geodesic action functional) and the number of conjugate points along the curve. Generalization of this theorem to linear elliptic boundary value problems appeared since seventies. (See, for instance, Smale (1965) [12], Uhlenbeck (1973) [15] and Simons (1968) [11] among others.) The aim of this paper is to prove a Morse–Smale index theorem for a second order self-adjoint el…

Dzīvnieku morālā statusa pamatošanas iespējamība: Pīters Singers un Endrū Linzijs

2020

Bakalaura darbā tiek pētīti utilitārisma ētikas pārstāvja Pītera Singera un kristīgās ētikas pārstāvja Endrū Linzija argumenti dzīvnieku morālā statusa pamatošanai. Skaidrojot abu autoru pozīcijas, izgaismojas, kādā veidā starp abiem autoriem varētu veidoties diskusija. Galvenais darba mērķis ir salīdzināt darba centrālo autoru argumentus dzīvnieka morālā statusa atzīšanai un noskaidrot, vai Linzija izpratne par kristīgo ētiku nodrošina tādus principus, kuriem varētu būt nozīme arī sekulāras dzīvnieku ētikas, tai skaitā Singera teorijas, kontekstā. Noslēgumā secināts, ka Linzija kristīgās ētika izpratne piedāvā šādu principu, kas ir dāsnuma paradigma. Tiek norādīts uz tādu attieksmi pret dz…

Andreklassingers arbeid med problemløsningsoppgaver : Et semiotisk perspektiv

2019

Masteroppgave matematikkdidaktikk MA502 – Universitetet i Agder 2019 This master thesis presentsaqualitative case study whichexplore year 2 students work with problem solving tasks, in a semiotic perspective. In the study, three small groups were observed while working with problem solving tasks. The aim of the observations where to getaninsight into which semiotic resources the students used while working onthe problem solving tasks. Video recordings from the observations make up the empirical data material of this study. This study is placed in the socio-cultural learning perspective. The aim of this study is to explore which semiotic resources the students use while working onproblem sol…

The Orbi Tradition: Blind Street Singers in Sicily

2019

In Sicily, the street music was primarily entrusted to a class of professional singers and players called orbi (“blind”). In 1661 orbi gathered in Palermo at the brotherhood of the Immaculate Conception under the protection of the Jesuits, marking their first official appearance in the historical record. The testimonies of the activity of orbi between the 18th and 19th centuries offers a detailed account of both their repertoire – composed mainly of sacred songs, but also of storii (“narrative songs”), canzuni (“songs”), ditties and dance music – and their performative contecxts. For instance, they were called to perform at religious celebrations, weddings and convivial events, serenades, a…

Place Identity e marcatezza diatopica nella canzone dialettale siciliana

2015

Il ritorno alla “località”, anche mediante il dialetto, quale simbolo di microspazialità fisica e culturale, con lo scopo di creare il necessario contrappunto al senso di straniamento e alienazione determinato dal modello globale, sembra particolarmente vero per la canzone dialettale contemporanea. Non sarà un caso, dunque, che molti autori neodialettali, già impegnati nella espressione di un’identità di luogo mediante il ricorso al dialetto che, in quanto tale, si configura come codice diatopicamente marcato e quindi intimamente legato a uno specifico spazio, non sanno fare a meno di richiamare nei propri testi, a puntello della “località” linguistica, contesti fisici del loro vissuto. Pot…

Laryngopathies by vocal abuse: clinical multidisciplinary evaluation in workers at risk

2014

Background: Attention to vocal pathologies in occupational categories that provide for a continuous use and often abuse of phonation has grown in recent decades. Objectives: Aim of this study was to evaluate presence of laryngopathies by vocal abuse in subjects occupationally exposed, namely teachers and singers, compared with non-exercising jobs at risk, also checking if self-assessment tests and spectrographic signals could be predictive of disease observed with endoscopy. Methods: We therefore proceeded to enroll on a voluntary basis, after information campaign, subjects, which in addition to an ananmnestic framework, underwent a multidisciplinary evaluation, which included, besides a fi…

Foreign Direct Investment, Terms of Trade, and Quality Upgrading: What Is So Special about South Asia?

2016

The existing literature has highlighted the positive effect of foreign direct investment (FDI) on export upgrading and associated terms of trade in developing economies. However, the FDI effect has been found to be negative in South Asia. In this paper, we elaborate on the South Asia-specific effect by emphasizing the role of human capital in the positive link between FDI and terms of trade. We argue that education levels in South Asia have lagged behind those in East Asia and other developing regions. This has resulted in a world market integration strategy in South Asia that specializes in less skills-intensive products and generates associated FDI flows. We demonstrate these patterns fo…
