    Background: Meta-analyses on the effectiveness of anti-bullying interventions show that average effects tend to be significant but small. Informed by the Vantage Sensitivity framework (Pluess and Belsky, 2013) the current study aims at testing whether individual differences in Environmental Sensitivity predict treatment response to an anti-bullying intervention. Method: Large randomized controlled trial with 2,042 pupils (grade 4 and 6) randomly assigned to a treatment or control condition. Results: Significant Intervention effects on victimization and internalizing symptoms (but not bullying or externalizing symptoms) were moderated by both Environmental Sensitivity and gender, with boys scoring high on sensitivity benefitting significantly more than less sensitive boys from the effects of the intervention regarding reduced victimization and internalizing symptoms. Conclusions: Findings are consistent with the notion of Vantage Sensitivity, suggesting that some individuals are disproportionately likely to respond to treatment while others are more resistant as a function of individual differences in environmental sensitivity

    Sub-National Scale Initiatives for Climate Change Mitigation: Refining the Approach to Increase the Effectiveness of the Covenant of Mayors

    Get PDF
    Climate change mitigation strategies include sub-national initiatives proposed and operated by municipalities. An example of such initiatives is the Covenant of Mayors, the signatories of which are requested to compile territorial greenhouse gas emission inventories to identify entry points for mitigating policies and to be able to monitor their effectiveness over time. However, the current accounting approach presents some limitations, providing an incomplete picture of the territorial emissive status, thus hampering the mitigation potential of the set of measures. The present study shows that the current approach required by the Sustainable Energy and Climate Action Plan (SECAP) guidelines for compiling the Baseline Emission Inventory (BEI) can be complemented with the accounting guidelines proposed by the Intergovernmental Panel on Climate Change (IPCC) in order to fill existing gaps and provide a comprehensive picture from a different point of view. The proposed refinement demonstrates that local administrative bodies can count on a tool able to provide detailed and accurate information, stimulate knowledge and awareness, and optimize local mitigation efforts sometimes limited by the application of large scale (national) top-down initiatives

    Adolescents' Ethnic Hate Speech Exposure and Ethnic Bullying Perpetration: The Moderating Role of Tolerance Towards Diversity and Gender

    Information and Communication Technologies have become powerful tools for adolescents, but they have enabled a huge number of online risks, such as being exposed to Online Hate Speech (OHS). High exposure to hateful content has been linked to despicable offline actions, including hate crimes. However, there is a lack of studies considering the associations with certain specific forms, such as the perpetration of bullying. The purpose of this study was to fill this gap in the literature by analysing the associations between exposure to OHS targeting ethnic minorities and ethnic bullying perpetration, and considering the potential moderating role of tolerance towards diversity and of gender. Participants were 960 high school students (53.6% females; Mage = 15 years, SD = 0.59). Data were collected in January/February 2020, before the first lockdown due to the Covid-19 pandemic. Findings suggest that being exposed to ethnic OHS is significantly, but weakly, associated with traditional ethnic bullying perpetration. Moreover, this association is moderated by tolerance towards diversity and by gender. In particular, for male adolescents, at low and middle levels of tolerance, higher ethnic OHS exposure is not associated with a higher tendency to perpetrate bullying toward peers with a different ethnicity. For females, instead, tolerance is not a moderator in the relationship between ethnic OHS exposure and ethnic bullying perpetration. Results are discussed in terms of their practical implications

    A rapid spectroscopic method to detect the fraudulent treatment of tuna fish with carbon monoxide

    Get PDF
    Carbon monoxide (CO) can be used to treat fresh meat and fish in order to retain its 'fresh' red colour appearance for a longer period of time. In fact, upon aging, myoglobin is oxidized to met-myoglobin with the concomitant blue-shift and broadening of the Soret maximum, which brings about a change in the colour of the fish, revealing that it is no longer fresh. The use of carbon monoxide, which reacts with the oxy-myoglobin to form a fairly stable cherry red carboxy-myoglobin complex may mask spoilage, because the CO-complex can be stable beyond the microbiological shelf life of the meat. The presence of CO in tuna fish has been investigated by optical spectroscopy as the formation of the CO adduct can be easily detected by the combined analysis of electronic absorption spectra in their normal and second derivative modes, monitoring the intense Soret band at 420 nm. The presence of met- and oxy-myoglobin can obscure the presence of small amounts of the CO adduct; however, it can be revealed by chemically reducing the met- and oxy-forms to the deoxy-form in an anaerobic environment. This spectroscopic method provides a qualitatively rapid laboratory screening procedure for food control to unmask the presence of CO in frozen or fresh fish. (c) 2006 Elsevier Ltd.

    Vibrational Raman and IR data on brown hair subjected to bleaching

    Get PDF
    Brown human hair was bleached three times (45 min × 3) and four times (45 min × 3 + 15 min) with commercial formulations containing persulfate salts and hydrogen peroxide. The hair samples were characterized by Raman and IR spectroscopy in the Attenuated Total Reflectance (ATR) mode to gain more insights into the possible secondary structure and Cα-Cβ-S-S-Cβ-Cα conformational changes induced by bleaching. The latter were evaluated through band-fitting procedures; the relative content of the disulfide bridges and oxidized sulfur species (cysteic acid, Bunte salt, cystine oxides) was assessed. The observed conformational changes could be significant in developing restoring agents to be used after hair decoloration. The use of two different spectroscopic techniques allowed to discriminate the information coming from the cortical region of hair (Raman) and the cuticle (ATR/IR).
