Towards a typology of negative engagement behavior in social media
2022
Extant literature on consumer engagement has focused on positive manifestations of the construct, rather than on its negative dimension. Yet, many brand interactions are negative in nature. The purpose of this conceptual study is to develop a typology of negative engagement behavior in social media by using the multi-grounded theory (MGT) approach on a sample of 12,429 tweets extracted from Twitter. The analysis shows that negative engagement behavior with a brand or service provider as the object focus or target can be categorized according to (a) the manifestation of the negative engagement and (b) the emotional intensity of the negative engagement. Four categories of negative engagement …
Benefits and drawbacks of communication visibility : from vicarious learning and supplemental work to knowledge reuse and overload
2022
Purpose This study aims to examine some of the benefits and drawbacks of communication visibility. Specifically, building on communication visibility theory, the authors study how and why message transparency and network translucence may increase knowledge reuse and perceived overload through behavioral responses of vicarious learning and technology-assisted supplemental work. Design/methodology/approach Drawing on survey data obtained from 1,127 employees of a global company operating in the industrial machinery sector, the authors used structural equation modeling to test the hypothesized model. Findings The results demonstrate that the two aspects of communication visibility yield somew…
Neutrino-nucleus scattering off 136Xe
2015
Background: Theoretical estimates of the cross sections for the neutrino-nucleus scattering off relevant nuclei for supernova neutrinos are essential for many applications in neutrino physics and astrophysics. The double- β-decaying nucleus 136Xe nucleus is used by the EXO Collaboration in the search for neutrinoless double-β decay. A ton-scale experiment based on 136Xe could also be used for studies of supernova neutrinos and/or solar neutrinos. Purpose: The purpose of the present work is, thus, to perform a study of the charged-current and neutral-current nuclear responses to supernova neutrinos for 136Xe. Method: The cross sections are computed by using the well-established framework for…
Nuclear structure and neutrino-nucleus reactions at supernova energies
2015
Supernova-(anti-)neutrino–nucleus scattering is discussed with reference to neutral-current (NC) and charged-current (CC) processes in heavy stable nuclei. The Donnelly-Walecka method with the associated multipole expansion of the nucleonic current has been adopted as the basic framework in deriving the neutrino-nucleus scattering cross sections. The needed nuclear wave functions are computed by using the quasiparticle random-phase approximation (QRPA) for the even-even target nuclei in the NC processes and the proton-neutron QRPA (pnQRPA) has been used to compute the CC processes for the mentioned nuclei. The wave functions of the stable odd-mass target nuclei have been obtained by the use…
Snowmass Neutrino Frontier: Neutrino Interaction Cross Sections (NF06) Topical Group Report
2022
A thorough understanding of neutrino cross sections in a wide range of energies is crucial for the successful execution of the entire neutrino physics program. In order to extract neutrino properties, long-baseline experiments need an accurate determination of neutrino cross sections within their detector(s). Since very few of the needed neutrino cross sections across the energy spectrum are directly measured, we emphasize the need for theoretical input and indirect measurements such as electron scattering, which would complement direct measurements. In this report we briefly summarize the current status of our knowledge of the neutrino cross sections and articulate needs of the experiments…

GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral
2017
On August 17, 2017 at 12-41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral. The signal, GW170817, was detected with a combined signal-to-noise ratio of 32.4 and a false-alarm-rate estimate of less than one per 8.0×104 years. We infer the component masses of the binary to be between 0.86 and 2.26 M, in agreement with masses of known neutron stars. Restricting the component spins to the range inferred in binary neutron stars, we find the component masses to be in the range 1.17-1.60 M, with the total mass of the system 2.74-0.01+0.04M. The source was localized within a sky region of 28 deg2 (90% probabili…
3D models acquisition and image processing for virtual musealization of the spezieria di Santa Maria della Scala, Rome
2022
This study was carried out within the project “Roma Hispana. Nuevas tecnologías aplicadas al estudio histórico, la musealización y la puesta en valor de Patrimonio Cultural español en Roma: la spezieria di Santa Maria della Scala” (Universitat de València Spain), which is funded by the Conselleria d’Innovació, Universitats, Ciència i Societat Digital of the Generalitat Valenciana (2020–2021) and authorized by the Sovrintendenza Speciale Archeologia Belle Arti e Paesaggio (Special Superintendence of Archeology, Fine Arts and Landscape) of Rome, Italy. The spezieria di Santa Maria della Scala was the oldest apothecary in…
Impacts sensoriels et non-sensoriels de la modification d’un attribut d’un produit alimentaire sur ses quantités consommées
2012
Cette recherche examine l’effet de la modification d’un attribut aux effets indésirables (la teneur en alcool du vin) sur la consommation d’un produit. En adoptant une perspective sensorielle, nous testons si la baisse de la quantité de l’attribut du nouveau produit (vin à 9 % d’alcool au lieu de 13,5 %) a une influence physiologique sur les quantités consommées. De même, en adoptant une perspective cognitive, nous examinons si l’information sur la baisse de cet attribut influence également les quantités consommées. Une expérimentation a été mise en œuvre avec deux groupes appariés de 33 individus consommant, soit un vin allégé en alcool (9 % vol.), soit un vin normal (13,5 % vol.), ceci pe…
