Search for Light Dark Matter Interactions Enhanced by the Migdal Effect or Bremsstrahlung in XENON1T.
2019
Direct dark matter detection experiments based on a liquid xenon target are leading the search for dark matter particles with masses above ∼5 GeV/c2, but have limited sensitivity to lighter masses because of the small momentum transfer in dark matter-nucleus elastic scattering. However, there is an irreducible contribution from inelastic processes accompanying the elastic scattering, which leads to the excitation and ionization of the recoiling atom (the Migdal effect) or the emission of a bremsstrahlung photon. In this Letter, we report on a probe of low-mass dark matter with masses down to about 85 MeV/c2 by looking for electronic recoils induced by the Migdal effect and bremsstrahlung us…
XENON1T Dark Matter Data Analysis: Signal Reconstruction, Calibration and Event Selection
2019
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above $6\,$GeV/$c^2$ scattering off nuclei. The detector employs a dual-phase time projection chamber with 2.0 metric tons of liquid xenon in the target. A one metric $\mathrm{ton}\times\mathrm{year}$ exposure of science data was collected between October 2016 and February 2018. This article reports on the performance of the detector during this period and describes details of the data analysis that led to the most stringent exclusion limits on various WIMP-nucleon interaction models to date. In pa…
Excess electronic recoil events in XENON1T
2020
We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 t-y and an unprecedentedly low background rate of $76\pm2$ events/(t y keV) between 1 and 30 keV, the data enables sensitive searches for solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter. An excess over known backgrounds is observed at low energies and most prominent between 2 and 3 keV. The solar axion model has a 3.4$\sigma$ significance, and a 3D 90% confidence surface is reported for axion couplings to electrons, photons, and nucleons. This surface is inscribed in the cuboid defined by $g_{ae}<3.8 \times 10^{-12}$,…
Sedación en el paciente geriátrico
2004
Se exponen la utilidad de la yatrosedación y de la sedación farmacológica para el tratamiento odontológico en el paciente anciano, su aplicación es necesaria debido a la mayor prevalencia de patología oral, peor tolerancia al estrés y a la asociación frecuente con patología sistémica. Se describen las vías de administración de psicofármacos más indicada según la patología asociada y a la interrelación farmacológica más frecuente con su patología de base. La fármaco-sedación siempre debe ir acompañada de un manejo psicológico para así minimizar las dosis y de una anestesia loco-regional correcta. A review is made of the utility of iatrosedation and pharmacological sedation in the dental trea…

Exploring the collaborative synthesis of information during online reading
2019
Abstract This descriptive study sought to understand the complexities of integrative processing during collaborative online reading. Student pairs constructed a collaborative understanding while reading online information about a controversial issue by connecting, combining and organizing information that originated from prior knowledge, self-selected online texts, and discussions during an online inquiry task. Thirty-eight students from an upper secondary school in Finland worked in pairs to read online information and write an essay with the help of an argument graph tool. Primary data sources consisted of: prior knowledge; discussions; notes recorded with a graphic representational tool;…
Videoconferencing analytic psychodrama in treating young adults’ psychological suffering: preliminary results
2023
The study aims to explore the effects that videoconferencing Analytic Psychodrama (AP) has on the psychological wellbeing and emotional competence of young adults who are suffering from mental health problems. Twenty-two undergraduate students, asking for help at the Psychological Counselling Service of the University of Bologna for anxiety-depressive problems, took part in the three online groups that met weekly from October 2020 to July 2021. The Clinical Outcomes in Routine Evaluation Outcome Measure, the Trait Emotional Intelligence Questionnaire Short Form, the Toronto Alexithymia Scale, the Interpersonal Reactivity Index, and the Group Climate Questionnaire were used as test–retest qu…
Relationships Between Career Indecision, Search for Work Self-Efficacy, and Psychological Well-Being in Italian Never-Employed Young Adults.
2017
Although different studies have investigated career choices as cognitive acts of decision-making, non-cognitive components also play an important role. The study tries to develop an empirically based model of career decision-making process linking cognitive (search for work self-efficacy - SWSE) and non-cognitive (psychological well-being - PWB) components. In particular, the study investigates, among 148 never-employed Italian young adults, to what extent the relationship between SWSE and career indecision in terms of lack of readiness (LoR) can be explained by their common relationship with PWB. Results highlighted that SWSE is negatively associated with LoR when considered in absence of …
Young women’s contradictory expectations and their perceived capabilities for future work-family reconciliation in Finland
2022
This paper explores young women’s expectations on future work-family reconciliation in Finland, a Nordic country well-known for the promotion of gender equality. Utilising Sen’s capabilities approach, we content-analysed thirty individual interviews to identify differences in women’s expectations and their perceived capabilities in future work and care. The results showed that irrespective of their labour market status and educational attainment, the women’s expectations were contradictory, reflecting a current Finnish gender culture that embraces both the ideal of shared parenthood and the primacy of maternal care. Between-group differences were also found. The employed women perceived the…
Staying inside : social withdrawal of the young, Finnish ‘Hikikomori’
2016
This article explores socially withdrawn young Finnish people on an Internet forum who identify with the Japanese hikikomori phenomenon. We aim to overcome the dualism between sociology and psychology found in earlier research by referring to Pierre Bourdieu, who provides insights into how individual choices are constructed in accordance with wider social settings. We focus on the individual level and everyday choices, but we suggest that psychological factors (anxiety, depression) can be seen as properties of social relations rather than as individual states of mind, as young adults have unequal access to valued resources. We scrutinise young people’s specific reasoning related to the soci…
