Making and breaking relationships on social media: the impacts of brand and influencer betrayals
2021
This study considers how the relationships between social media influencers, brands and individuals are intertwined on social media and analyses the spill-over effects of feelings of betrayal. An experimental design with two transgression scenarios (influencer vs. brand) was created, and 250 individuals were recruited to participate in the study. The results show that a perceived betrayal by a brand can negatively affect the perceived coolness of the social media influencer that has endorsed the brand, as well as the parasocial relationships that followers have with the influencer. Accordingly, a perceived betrayal by a social media influencer can negatively affect attitudes, trust and purc…
Il satiro come maestro di moralità. Una stravagante invenzione di Jan Kochanowski
2016
Three visits of Jan Kochanowski in Padua, at that time under the rule of the Republic of Venice which influenced both cultural and intellectual life in the city, had a considerable impact on his literary output. This essay proves that there was a significant mark of the Serenissima entering into the theatrical life, related to one of his earliest texts, Satyr albo Dziki Mąz (The Satyr or the wild Man), dedicated to the king Sigismund II August and published presumably for the first time in 1563. An unsolved issue concerns not only the idea of making the Satyr a morality teacher, but also the question whether it was just a text meant for reading or for being performed in a theatrical form. T…
Uloga glazbe u dubrovackom pastoralnom teatru u 16. stoljecu. (The Role of the Music in the Pastoral Theatre in Dubrovnik during the Sixteenth Centur…
2004
The 16th-century pastoral plays in Dubrovnik (Ragusa), like the Italian ones which inspired them, are marked by the strong presence of sounds, songs and choruses to increase the fantastical and sentimental emphasis of the performances. Their evolution, from Dzore Drzic eclogues to the pastorals of Antun Sasin, and through Mauro Vetranovic's "Orfeo", is characterized by the acquisition of a Petrarchian language in the Croatian pieces of Nikola Naljeskovic. In the Dubrovnik pastoral plays, unlike the Italian ones, the presence of shepherds, nymphs, and rustic men (the "vlasi", Engl. Walachians or Morlacks) as well as the fantastic and comic elements, is constant. Music supports a narrative fu…
Radiation effects in transparent ferroelectric ceramics
1997
Radiation of different types ((gamma) -rays, electrons, neutrons) and fluence has been used to study the defect processes as well as the change of physical parameters in PLZT X/65/35 (X equals 4.5 - 11 at.%) and PbSc 0.5 Nb 0.5 O 3 (PSN) ceramics and to evaluate critical irradiation conditions. Effects on optical (extinction) spectra and dielectric characteristics (polarization, thermal and frequency dependences of dielectric permittivity (epsilon) and losses), dependent on composition and state of phase and polarization have been analyzed by means of annealing in isochronic and prolonged time regimes. A gradual shift of extinction edge to longer wavelengths, reduction of polarization and (…
ÉTICA DE LOS CREYENTES
2011
In this paper I analyze the relationship between religious beliefs of individuals and their attitudes to certain moral and political issues. In some cases, certain behaviours of believers contradict the doctrines of the religions that they claim to profess, although they don’t feel less faithful. This dissonance between religious doctrines and beliefs of a religion’s followers can be explained through the concept of the privatization of religious beliefs, according to which at present, religious beliefs have lost their objectivity in the context of moral monism. Thus, the believers’ convictions are influenced by the social influences on the way the believer understand
Alpha and deuteron irradiation effects on silica nanoparticles
2014
We present an experimental investigation focused on the effects of alpha and deuteron irradiation on different silica nanoparticles. The study has been devoted also to characterize the induced point defects and the eventual structural modifications to evaluate the effects of the different irradiation source in comparison with the bulk materials. After irradiation up to about 10^16 ions cm^-2, we performed electron paramagnetic resonance (EPR), photoluminescence (PL), infrared (IR) absorption, Raman, and atomic force microscopy (AFM) measurements. We found that the two types of irradiation qualitatively induce comparable effects. Furthermore, irradiation generates the socalled twofold coordi…
Collision-kerma conversion between dose-to-tissue and dose-to-water by photon energy-fluence corrections in low-energy brachytherapy
2016
The AAPM TG-43 brachytherapy dosimetry formalism, introduced in 1995, has become a standard for brachytherapy dosimetry worldwide; it implicitly assumes that charged-particle equilibrium (CPE) exists for the determination of absorbed dose to water at different locations, except in the vicinity of the source capsule. Subsequent dosimetry developments, based on Monte Carlo calculations or analytical solutions of transport equations, do not rely on the CPE assumption and determine directly the dose to different tissues. At the time of relating dose to tissue and dose to water, or vice versa, it is usually assumed that the photon fluence in water and in tissues are practically identical, so tha…
Concentration depending fluorescence of 8-(di-(2-picolyl)) aminoBODIPY in solution
2014
[EN] An 8-dipicolylBODIPY derivative has been prepared and its photophysical properties evaluated under different conditions. Two different structures, hemicyanine and cyanine, are observed (depending on the solvent or the solution concentration). The hemicyanine form is not emissive whereas the cyanine form is fluorescent. This behavior is related with the planarity degree of the BODIPY core. The X-ray structure of the compound is reported and it shows that in solid state the hemicyanine form is present. The hemicyanine form seems to be stabilized by aggregation and is the main compound in concentrated solutions whereas the cyanine form is present in diluted solutions that are photochemica…
Simulation and experimental investigations on dynamic after cavity interaction (ACI)
2010
In recent years, the so called after cavity interaction (ACI) in high power gyrotrons operating in the 100–200 GHz range gained attention as an influence factor on overall efficiency. While investigations concentrated on ACI as a stationary effect until now, recent simulations show that an undesired interaction in the uptaper region can also result in additional parasitic oscillations. In this paper, such non-stationary, dynamic processes are investigated in first simulations and experiments.
Charge collection efficiency and resolution of an irradiated double-sided silicon microstrip detector operated at cryogenic temperatures
1999
Abstract This paper presents results on the measurement of the cluster shapes, resolution and charge collection efficiency of a double-sided silicon microstrip detector after irradiation with 24 GeV protons to a fluence of 3.5×10 14 p/cm 2 and operated at cryogenic temperatures. An empirical model is presented which describes the expected cluster shapes as a function of depletion depth, and is shown to agree with the data. It is observed that the clusters on the p-side broaden if the detector is under-depleted, leading to a degradation of resolution and efficiency. The model is used to make predictions for detector types envisaged for the LHC experiments. The results also show that at cryo…
