“You Cannot Get into My Taxi!” Perceptions of a COVID-19-based rejection episode reported in the newspapers
COVID-19-related incidents of xenophobia have hit the headlines. We asked participants to read about a rejection episode targeting a foreigner and we manipulated whether the rejection was motivated by COVID-19 fears or by no specific reasons. In the COVID-19 condition, the perpetrator was perceived as moral but as experiencing shame and guilt, while the target was seen as experiencing social pain. Helping intentions were predicted by either the perceived victim's social pain or morality and blame associated with the perpetrator.info:eu-repo/semantics/acceptedVersio
When characters impact on dubbing: the role of sexual stereotypes on voice actor/actress’ preferences
Dubbing is a procedure through which an original actor’s voice is replaced with that of a voice actor, usually speaking a different language. Dubbing is not only an adaptation to language but also to cultural beliefs. Across two studies, we analyzed how some Italian participants would prefer a television series’ character to sound. In Study 1, participants read a male/female character description that was manipulated according to gender and sexual stereotypes in order to be masculine, feminine, or gender-neutral. Next, participants were asked to indicate their preference for three voice actors/actresses who sounded heterosexual, gay/lesbian, or ambivalent. Study 2 tested the interplay between a character’s description and the voice of the English-speaking (gay/lesbian vs. heterosexual sounding) actor/actress who played the role in the original television series on dubbing preferences. The results of both studies showed that a character’s description affected dubbing preferences. Participants preferred the gay/lesbian-sounding voice actor/actress to the counter-stereotypical character (i.e., a feminine man or a masculine woman) and the heterosexual-sounding voice actor/actress to the stereotypical character. Interestingly, at least for male targets, the original actor’s voice itself affected the preference for voice actors in the same way. This work suggests that dubbing can maintain and reinforce stereotypes.info:eu-repo/semantics/acceptedVersio
Raman Spectroscopy of Graphene Edges
Graphene edges are of particular interest since their orientation determines the electronic properties. Here we present a detailed Raman investigation of graphene flakes with edges oriented at different crystallographic directions. We also develop a real space theory for Raman scattering to analyze the general case of disordered edges. The position, width, and intensity of G and D peaks are studied as a function of the incident light polarization. The D-band is strongest for polarization parallel to the edge and minimum for perpendicular. Raman mapping shows that the D peak is localized in proximity of the edge. For ideal edges, the D peak is zero for zigzag orientation and large for armchair, allowing in principle the use of Raman spectroscopy as a sensitive tool for edge orientation. However, for real samples, the D to G ratio does not always show a significant dependence on edge orientation. Thus, even though edges can appear macroscopically smooth and oriented at well-defined angles, they are not necessarily microscopically ordered
Gay- and Lesbian-Sounding Auditory Cues Elicit Stereotyping and Discrimination
Thegrowing bodyof literatureonthe recognition of sexual orientation from voice (‘‘auditory gaydar’’) is silent on the cognitive and social consequences of having a gay-/lesbianversus heterosexual-sounding voice.We investigated this issue in four studies (overall N=276), conducted in Italian language, in which heterosexual listeners were exposed to single-sentence voice samples of gay/lesbian and heterosexual speakers. In all four studies, listeners were found to make gender-typical inferences about traits and preferences of heterosexual speakers, but gender-atypical inferences about those of gay or lesbian speakers. Behavioral intentionmeasures showed that listeners considered lesbian and gay speakers as less suitable for a leadership position, andmale (but not female) listeners took distance from gay speakers. Together, this research demonstrates that having a gay/ lesbian rather than heterosexual-sounding voice has tangible consequences for stereotyping and discrimination

First insights into the urinary metabolome of captive giraffes by proton nuclear magnetic resonance spectroscopy
The urine from 35 giraffes was studied by untargeted1H-NMR, with the purpose of obtaining, for the first time, a fingerprint of its metabolome. The metabolome, as downstream of the transcriptome and proteome, has been considered as the most representative approach to monitor the relationships between animal physiological features and environment. Thirty-nine molecules were unambiguously quantified, able to give information about diet, proteins digestion, energy generation, and gut-microbial co-metabolism. The samples collected allowed study of the effects of age and sex on the giraffe urinary metabolome. In addition, preliminary information about how sampling procedure and pregnancy could affect a giraffe\u2019s urinary metabolome was obtained. Such work could trigger the setting up of methods to non-invasively study the health status of giraffes, which is utterly needed, considering that anesthetic-related complications make their immobilization a very risky practice
Fast visible imaging of turbulent plasma in TORPEX
Fast framing cameras constitute an important recent diagnostic development aimed at monitoring light emission from magnetically confined plasmas, and are now commonly used to study turbulence in plasmas. In the TORPEX toroidal device [A. Fasoli et al., Phys. Plasmas 13, 055902 (2006)], low frequency electrostatic fluctuations associated with drift-interchange waves are routinely measured by means of extensive sets of Langmuir probes. A Photron Ultima APX-RS fast framing camera has recently been acquired to complement Langmuir probe measurements, which allows comparing statistical and spectral properties of visible light and electrostatic fluctuations. A direct imaging system has been developed, which allows viewing the light, emitted from microwave-produced plasmas tangentially and perpendicularly to the toroidal direction. The comparison of the probability density function, power spectral density, and autoconditional average of the camera data to those obtained using a multiple head electrostatic probe covering the plasma cross section shows reasonable agreement in the case of perpendicular view and in the plasma region where interchange modes dominate.This work is partly funded by the “Fonds National

Les sables de Fontainebleau: a natural quartz reference sample and its characterisation
Fundamental studies on luminescence production
in natural quartz require samples
which can be studied by groups of laboratories
using complementary methods. In the framework
of a European collaboration studying
quartz luminescence, a sample originating
from the Fontainebleau Sandstone Formation
in France was selected for characterisation
and distribution to establish a starting point
for interlaboratory work. Here we report on
the preparation and characterisation work
undertaken before distribution with the aim
of ensuring that each laboratory received
comparable material. Material was purified to
enrich the quartz concentration, followed by
mineralogical screening by SEM and ICP-MS
analyses. Luminescence screening measurements
were undertaken at a single laboratory
(SUERC) to verify the suitability of the sample
for use within the study, and to establish the
level of homogeneity of subsamples prepared
for distribution. The sample underwent minimal
non-chemical pre-treatment by multiple
cycles of magnetic separation and annealing.
SEM analysis showed that the sample
consists mainly of SiO2. The luminescence
characterisation confirmed a dose sensitivity
of ca. 22,000–160,000 cts K−1 Gy−1 per 260–
290 grains for the 110◦C UV TL peak, well
developed low (here: 100–300◦C) temperature
(pre-dose) TL signals and high OSL sensitivities.
The grain to grain OSL response varies by
more than one order of magnitude. No significant
IRSL signal was observed. In summary,
the results from luminescence characterisation
confirm the suitability of the sample for the
luminescence experiments envisaged and have
established a basis for comparability in studies
conducted by a network of laboratories
Voice changes meaning: the role of gay- versus straight-sounding voices in sentence interpretation
Utterances reveal not only semantic information but also information about the speaker’s social category membership, including sexual orientation. In four studies (N = 345), we investigated how the meaning of what is being said changes as a function of the speaker’s voice. In Studies 1a/1b, gay- and straight-sounding voices uttered the same sentences. Listeners indicated the likelihood that the speaker was referring to one among two target objects varying along gender-stereotypical characteristics. Listeners envisaged a more “feminine” object when the sentence was uttered by a gay-sounding speaker, and a more “masculine” object when the speaker sounded heterosexual. In Studies 2a/2b, listeners were asked to disambiguate sentences that involved a stereotypical behavior and were open to different interpretations. Listeners disambiguated the sentences by interpreting the action in relation to sexual-orientation information conveyed by voice. Results show that the speaker’s voice changes the subjective meaning of sentences, aligning it to gender-stereotypical expectations.info:eu-repo/semantics/acceptedVersio
Urinary reference values and first insight into the urinary proteome of captive giraffes
Urinalysis is widely recognized to be a useful tool in routine health investigations, since it can diagnose numerous pathologies. Considering the paucity of knowledge concerning giraffes, urine from 44 giraffes (Giraffa camelopardalis) (18 males and 26 females, from 3 months of age to 21 years of age) underwent routine urinalysis, 1D-electrophoresis, and protein identification using mass spectrometry, with the aim of identifying the urinary reference values and the urine proteome. The urine specific gravity (USG), urine total proteins (uTP), urine creatinine (uCr), and urine protein:creatinine ratio (UPC) reference values, reported as the median, and lower limit (LL) and upper limit (UL), were 1.030 (1006\u20131.049), 17.58 (4.54\u201335.31) mg/dL, 154.62 (39.59\u2013357.95) mg/dL, and 0.11 (0.07\u20130.16), respectively. Mass spectrometry, together with electrophoresis, revealed a pattern of common urinary proteins; albumin, lysozyme C, and ubiquitin were the most represented proteins in the giraffe urine. It has been hypothesized that these proteins could act as a defense against microbes. Moreover, in giraffes, urinalysis could be a valid tool for gauging renal function and physiological status changes
