No full textA study on the implementation of dual career at European higher education institutions: the student-athletes' and experts' views
No full textIntroduction: The holistic development of elite athletes is a priority within European sports policies, necessitating a coordinated approach to dual career support. This study evaluated the perspectives of both university experts and student-athletes (S-As) on various dual career aspects, aiming to provide actionable insights for improving policies within European higher education institutions (HEIs). Materials and methods: Data was collected through an online survey tailored for HEI experts and S-As across multiple countries. A total of 46 HEI experts and 321 S-As responded to the survey. The role of the country of origin on each dual career aspect for S-As was investigated using a MANOVA, followed by an ANOVA and post hoc analyses using Tukey's test when an effect emerged. The data from HEI experts and comparisons between S-As and HEI experts were handled descriptively due to the violation of assumptions of homogeneity of variances and sufficient sample size. Results: The study revealed significant trends and disparities in the availability and quality of support services. In particular, logistic, and financial support, and other support/policies areas showed a significant effect for S-As countries of origin, with Romanian and Serbian S-As generally reporting better scores and Italian and Spanish worse. In general, HEI experts rated dual career provision areas more favorably than S-As. Conclusion: This study underscores the importance of integrating both HEI expert and S-As' perspectives to develop effective dual career policies. Tailored interventions and enhanced communication about available resources are crucial for improving the dual career experiences of S-As across Europe

Kinetics of Different Substituted Phenolic Compounds’ Aqueous OH Oxidation in Atmosphere
No full textAtmospheric aqueous-phase reactions have been recognized as an important source of secondary organic aerosols (SOAs). However, the unclear reaction kinetics and mechanics hinder the in-depth understanding of the SOA sources and formation processes. This study selected ten different substituted phenolic compounds (termed as PhCs) emitted from biomass burning as precursors, to investigate the kinetics using OH oxidation reactions under simulated sunlight. The factors influencing reaction rates were examined, and the contribution of reactive oxygen species (ROS) was evaluated through quenching and kinetic analysis experiments. The results showed that the pseudo-first-order rate constants (kobs) for the OH oxidation of phenolic compounds ranged from 1.03 × 10−4 to 7.85 × 10−4 s−1 under simulated sunlight irradiation with an initial H2O2 concentration of 3 mM. Precursors with electron-donating groups (-OH, -OCH3, -CH3, etc.) exhibited higher electrophilic radical reactivity due to the enhanced electron density of the benzene ring, leading to higher reaction rates than those with electron-withdrawing groups (-NO2, -CHO, -COOH). At pH 2, the second-order reaction rate (kPhCs, OH) was lower than at pH 5. However, the kobs did not show dependence on pH. The presence of O2 facilitated substituted phenols’ photodecay. Inorganic salts and transition metal ions exhibited varying effects on reaction rates. Specifically, NO3− and Cu2+ promoted kPhCs, OH, Cl− significantly enhanced the reaction at pH 2, while SO42− inhibited the reaction. The kPhCs, OH were determined to be in the range of 109~1010 L mol−1 s−1 via the bimolecular rate method, and a modest relationship with their oxidation potential was found. Additionally, multiple substituents can suppress the reactivity of phenolic compounds toward •OH based on Hammett plots. Quenching experiments revealed that •OH played a dominant role in phenolic compound degradation (exceeding 65%). Electron paramagnetic resonance confirmed the generation of singlet oxygen (1O2) in the system, and probe-based quantification further explored the concentrations of •OH and 1O2 in the system. Based on reaction rates and concentrations, the atmospheric aqueous-phase lifetimes of phenolic compounds were estimated, providing valuable insights for expanding atmospheric kinetic databases and understanding the chemical transformation and persistence of phenolic substances in the atmosphere
Optimal reinsurance in a dynamic contagion model: comparing self-exciting and externally-exciting risks
No full textWe investigate the optimal reinsurance problem in a risk model with jump clustering features. This modeling framework is inspired by the concept initially proposed in Dassios and Zhao [A dynamic contagion process. Adv. Appl. Probab., 2011, 43, 814-846], combining Hawkes and Cox processes with shot noise intensity models. Specifically, these processes describe self-exciting and externally excited jumps in the claim arrival intensity, respectively. The insurer aims to maximize the expected exponential utility of terminal wealth for general reinsurance contracts and reinsurance premiums. We discuss two different methodologies: the classical stochastic control approach based on the Hamilton-Jacobi-Bellman (HJB) equation and a backward stochastic differential equation (BSDE) approach. In a Markovian setting, differently from the classical HJB-approach, the BSDE method enables us to solve the problem without imposing any requirements for regularity on the associated value function. We provide a Verification Theorem in terms of a suitable BSDE driven by a two-dimensional marked point process and we prove an existence result relaying on the theory developed in Papapantoleon et al. [Existence and uniqueness results for BSDE with jumps: the whole nine yards. Electron. J. Probab., 2018, 23, 1-68] for stochastic Lipschitz generators. After discussing the optimal strategy for general reinsurance contracts and reinsurance premiums, we provide more explicit results in some relevant cases. Finally, we provide comparison results that highlight the heightened risk stemming from the self-exciting component in contrast to the externally-excited counterpart and discuss the monotonicity property of the value function
Una conferma della multietnicità iadertina: il liber baptizatorum della Chiesa di Sant’Elia Profeta a Zara (DAZ: inv. n. 1531)
No full textNel presente lavoro viene analizzata la sezione in lingua italiana del manoscritto
del registro delle nascite, in realtà r egistro dei battesimi, della chiesa
di Sant’Elia Profeta a Zara, conservato presso l’Archivio di Stato di Zara
(DAZ: inv. n. 1531). Come ogni registro parrocchiale riporta gli eventi più
significativi della sua comunità di riferimento, nel caso specifico nell’arco
temporale 1637-1776. La chiesa di Sant’Elia Profeta, sorta come luogo di
culto cattolico e passata, nel 1578, a quello greco-ortodosso, è stata oggetto
di descrizione da parte di studiosi come G. Ferrari-Cupilli (1854), C.F.
Bianchi (1877) e G. Sabalich (1897). Tali documenti sono un’importante
testimonianza di quei secoli, ma soprattutto una conferma della vocazione
multietnica della città dalmata. Del registro vengono qui presi in esame gli
elementi formali, una selezione di dati demografici, onomastici e toponomastici,
nonché specifici aspetti lessicali e/o linguistici

No full textThe Nrf2-Related Pathways and the Antiandrogenic Effects Are Enhanced In Vitro and In Silico by the Combination of Graminex®G96® Pollen and Teupol 25P in Cell Models of Benign Prostate Hyperplasia
No full textInflammation, oxidative stress, and androgen activity are key features in benign prostate hyperplasia (BPH). Risks associated with the long-term use of 5α-reductase inhibitors have led to the search for alternative therapies, including food supplements. This study investigates the effectiveness of the combination of pollen extracts, namely Graminex®G96® (G) and Teupol 25P (T), towards oxidative stress and inflammation on human macrophages and benign prostate hyperplasia cells (BPH-1), both of which are LPS stimulated. The Nrf2-dependent antioxidant intracellular cascade as well as the NF-ĸB-driven inflammatory cascades were analyzed. The anti-proliferative effect of G and T, alone and in association, were evaluated on prostatic adenocarcinoma cells (PC-3) and BPH-1 cells. Finally, the inhibitory activity of GT on 5α-reductase was investigated in PC-3 cells by measuring epiandrosterone amounts, with the 5α-reductase inhibitor finasteride administered for comparison. All experiments were conducted in triplicate; data are presented as mean values ± standard deviations. Statistical analysis was performed using one-way analysis of variance. Our work demonstrates that GT promotes Nrf2-dependent antioxidant responses and counteracts the NF-ĸB-driven pathway in macrophages. GT is effective in counteracting the expression of pro-inflammatory cytokines and the generation of reactive oxygen species by promoting HO-1-dependent antioxidant responses in BPH-1 cells. GT reduces PC-3 and BPH-1 proliferation when associated with finasteride through a statistically significant inhibition of 5α-reductase activity. Data obtained in vitro and in silico demonstrate the potential efficacy of a multitargeted approach in the treatment of BPH
When efficient help is perceived as greed: experimental evidence
No full textWe study charitable behaviour when genuine donations can be misinterpreted as being greedy. This is relevant when private benefits from donating, like tax exemptions, bring into question whether donors are truly altruistically motivated. In our experiment, a potential donor, the distributor, decides how to split a sum of money between themselves, a paired non-distributor, and a charity of their choice. Choosing to donate part of the sum to charity is socially efficient because the charity receives four times the amount, with the difference covered by the experimenters. Our conditions vary in the choice set available to the distributor and whether the choice set becomes known to the non-distributor. With the choice set unknown, the distributor may be concerned that the non-distributor will believe the money has been split unfairly, with the distributor keeping a larger share. Overall, we find this not to be the case: the number of individuals who donate to charity is not significantly lower when donating could be perceived as greedy
