Wolność wyboru rodzaju działalności naukowej a przesłanki ustawowe uzyskania tytułu naukowego profesora
2022
Niniejsze opracowanie dotyczy analizy ustawowych kryteriów dla przyznania tytułu profesora, w ramach tak zwanej Konstytucji dla Nauki. W treści artykułu postawiono nacisk na swobodę wyboru formy aktywności naukowej dla kandydata do tytułu profesora, jaka wynika z treści ustawy. Ustawodawca użył złożonej normy prawnej dla ustalenia kryteriów dla kandydata do tytułu profesora. Może ona budzić wątpliwości zarówno praktyczne, jak i teoretyczne
Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light
2017
Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…
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 $g_{ae}<3.8 \times 10^{-12}$,…
Always in crisis, always a solution? : The Nordic model as a political and scholarly concept
2021
While campaigning for the 2016 US Democratic Party presidential nomination, Senator Bernie Sanders invoked the Nordic countries as a model for future politics. In a debate, he declared, ‘I think we should look to countries like Denmark, like Sweden and Norway, and learn from what they have accomplished for their working people.’1 Hailing the Nordic countries, especially Denmark, as an example of ‘democratic socialism’,2 Sanders’s vision engendered a heated debate, with political opponents critiquing the implied political agenda, the prime minister of Denmark protesting the idea of Denmark as a socialist country, and journalists and pundits presenting corrective views of the economic and soc…
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;…
Physical activity from adolescence to young adulthood: patterns of change, and their associations with activity domains and sedentary time
2021
Background Longitudinal studies demonstrate an average decline in physical activity (PA) from adolescence to young adulthood. However, while some subgroups of adolescents decrease activity, others increase or maintain high or low activity. Activity domains may differ between subgroups (exhibiting different PA patterns), and they offer valuable information for targeted health promotion. Hence, the aim of this study was to identify PA patterns from adolescence to young adulthood; also to explore the associations of (i) changes in PA domains and in sedentary time, (ii) sociodemographic factors, and (iii) self-rated health with diverging PA patterns. Methods The observational cohort study data …
Get up, stand up: Alongside adolescents and young adults with cancer for their right to be forgotten
2022
Adolescent and young adult cancer survivors may experience various forms of social difficulties years or even decades after completing their cancer treatments. This article will hopefully help the Italian national project dedicated to adolescents and young adults with cancer promoting political and legal solutions to stop discrimination and supporting the right to be forgotten.
How Do Young Adults Orchestrate Their Multiple Achievement-Related Goals? Associations of Achievement Goal Orientations With Identity Formation and G…
2016
Young adults strive for multiple achievement goals. Frameworks for achievement goal orientations, personal goals, and identity formation have emphasized the role of goal-specific exploration and commitment in the interpretation of goals. However, researchers have yet to combine these different perspectives in an empirical study. Therefore, to explore the processes involved in the selection of multiple goals, the present study investigated the associations of young adults’ achievement goal orientations (mastery-intrinsic, mastery-extrinsic, performance-approach, performance-avoidance, and work-avoidance orientations) with distinct styles of exploring and committing to goals, by considering d…
