Formation and Mitigation of Technostress in the Personal Use of IT
2022
Understanding information technology (IT) use is vital for the information systems (IS) discipline due to its substantial positive and negative consequences. In recent years, IT use for personal purposes has grown rapidly. Although personal use is voluntary and can often reflect fun, technostress is a common negative consequence of such use. When left unaddressed, technostress can cause serious harm to IT users. However, prior research has not explained how technostress forms over time or how its mitigation takes place in a personal—rather than organizational—environment. To address these research gaps, we conducted a qualitative study with narrative interviews of IT users who had experienc…
Comparison of essential oil components and in vitro anticancer activity in wild and cultivated Salvia verbenaca.
2015
The objectives of our research were to study the chemical composition and the in vitro anticancer effect of the essential oil of Salvia verbenaca growing in natural sites in comparison with those of cultivated (Sc) plants. The oil from wild (Sw) S. verbenaca presented hexadecanoic acid (23.1%) as the main constituent, while the oil from Sc plants contained high quantities of hexahydrofarnesyl acetone (9.7%), scarce in the natural oil (0.7%). The growth-inhibitory and proapoptotic effects of the essential oils from Sw and Sc S. verbenaca were evaluated in the human melanoma cell line M14, testing cell vitality, cell membrane integrity, genomic DNA fragmentation and caspase-3 activity. Both t…

Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
Semantica ed epistemologia di techne nella Grecia antica
2016
Sulla scorta del libro di Claude Calame intitolato "Prometeo genetista" e di cui l'A. ha curato parte della traduzione italiana, viene indagata l'ampia gamma di significati propri del termine greco "techne" e della corrispondente radice. La ricerca riguarda in particolare il valore semantico proprio del termine, che si contraddistingue, alla luce dell'analisi condotta sulle più antiche attestazioni nella letteratura greca sino al IV secolo a.C., come una vera e propria "vox media". Il carattere sostanzialmente medio del termine, evidente nell'uso linguistico di autori quali Eschilo e Sofocle, si connota più o meno positivamente a seconda della valutazione del singolo autore, e in primo luog…
Zabieg medycyny estetycznej w przypadku małoletniego dziecka bez zgody sądu rodzinnego a odpowiedzialność prawnokarna
2017
This article refers to criminal liability for performing aesthetic medicine treatment in a form of plastic surgery without patient’s consent, substitute consent (including collective) or substitute consent of Family Court. Article presents the current state of law in this respect and the correlation between applicable regulations of various branches of law and lex generalis regulations that deal with this issue, i.e. aesthetic medicine treatment.The author evaluates and describes the legal issues related with aesthetic medicine, including the patient’s consent, extended disclosure obligation as well as the ground for statutory liability for committing a prohibited act that is described and …
Economical evaluation of ecological benefits of the demand side management
2014
Environmental pollution and over-exploitation of non-renewable sources to find energy are current topics for the modern world that is now at having to deal with several issues such as the greenhouse effect, acid rain and climate change. In this study, the economical estimate of the savings in carbon dioxide obtained with a careful management of electrical loads is presented. Four particular scenarios are designed as case studies: Italy, France, United Kingdom and Germany. A comparison is presented with a similar study, made in 2007, when green energies were not yet very developed.
Operator (Quasi-)Similarity, Quasi-Hermitian Operators and All that
2016
Motivated by the recent developments of pseudo-Hermitian quantum mechanics, we analyze the structure generated by unbounded metric operators in a Hilbert space. To that effect, we consider the notions of similarity and quasi-similarity between operators and explore to what extent they preserve spectral properties. Then we study quasi-Hermitian operators, bounded or not, that is, operators that are quasi-similar to their adjoint and we discuss their application in pseudo-Hermitian quantum mechanics. Finally, we extend the analysis to operators in a partial inner product space (pip-space), in particular the scale of Hilbert space s generated by a single unbounded metric operator.
Jacobi Fields, Conjugate Points
2001
Let us go back to the action principle as realized by Jacobi, i.e., time is eliminated, so we are dealing with the space trajectory of a particle. In particular, we want to investigate the conditions under which a path is a minimum of the action and those under which it is merely an extremum. For illustrative purposes we consider a particle in two-dimensional real space.
