Genealogy of the Ethics of Teacher Self-Evaluation
2022
Quality evaluation (QE) has assumed major importance in governing education. QE is acknowledged as a self-evident and necessary method of improving quality in education across education systems. Along with the quality ‘evaluation wave’, schools and teachers have not only become objects of evaluation, but have also been subjected to increasing demands to self-evaluate. Using genealogical methodology, this chapter analyses the emergence and formation of the politics of school and teacher self-evaluation and also the power and subjectivities invoked through it in the case of Finnish comprehensive education. The research material includes curricular, legislative and education policy texts and n…
Regression analysis of the nuclear symmetry energy for relativistic mean-field models
2022
Regression analysis for the symmetry energy within a sample of relativistic mean-field models of nuclear matter is performed. The selected models consistently meet the experimentally obtained limitations. A proposed measure of the importance of adding the fourth-order term to the symmetry energy is analyzed. As a result of the research, it became possible to arrange the models and perform two-dimensional and one-dimensional linear regression analyses. The one-dimensional regression analysis between the input parameters confirms the appropriateness of introducing the division of the sample of considered models into four separate classes representing four statistically different fits. An addi…
Approccio integrato per la caratterizzazione delle murature storiche siciliane. Il caso di Gangi
2022
This study is part of a research aimed at developing a database of mechanical and hygrothermal information for Sicilian historic walls. This database is intended to support the analysis of the envelope performances of the historic building and to integrate data collected through in-situ measurements. The method is based on the analysis of local contexts: stone walls are divided in typologies according to the detailed non-destructive examination of the historic building stock, and laboratory and in-situ tests are carried out to characterize the mechanical and thermophysical properties of walls and masonry materials. This study focuses on the local context of Gangi, where a large amount of hi…
Light-front wavefunctions of mesons by design
2022
AbstractWe develop a mechanism to build the light-front wavefunctions (LFWFs) of meson bound states on a small-sized basis function representation. Unlike in a standard Hamiltonian formalism, the Hamiltonian in this method is implicit, and the information of the system is carried directly by the functional form and adjustable parameters of the LFWFs. In this work, we model the LFWFs for four charmonium states, $$\eta _c$$ η c , $$J/\psi $$ J / ψ , $$\psi '$$ ψ ′ , and $$\psi (3770)$$ ψ ( 3770 ) as superpositions of orthonormal basis functions. We choose the basis functions as eigenfunctions of an effective Hamiltonian, which has a longitudinal confining potential in addition to the transver…

Contrasting responses of vascular plants and bryophytes to present and past connectivity in unmanaged grasslands
2022
AbstractThe area of semi-natural grasslands has decreased dramatically causing many grassland specialist species to persist in small habitat fragments. Furthermore, ecological communities once shaped by disturbances related to traditional agriculture now face the impacts of modern agriculture and urbanization. Many of the species have become endangered due to the combined effects of habitat destruction and degradation. We studied the responses of vascular plants and bryophytes to present and past connectivity in semi-natural grasslands, while accounting for the effects of local environmental conditions. We conducted vegetation surveys in 33 fragmented, unmanaged dry grasslands in Southwest …
On Supervising Master’s Theses in Industry Context
2022
In software engineering, students easily find internships in companies while still studying. To combine their studies and employment, many of them seek to compose their final theses in an industry context, for the benefit of the employer as well as to simplify their context switching between job and studies. This can put the student between a rock and a hard place, as on one hand the employer has certain expectations in terms of working for the company, whereas the supervising professor needs to follow the university guidelines. An additional aspect worth considering is the university as an administrative home for the thesis and owner of the thesis process. In this paper, we study how the d…

La Educación para la Ciudadanía cumple con esta función y su implementación en los sistemas educativos de los países es muy diversa, dando como resultado diferentes ciudadanos.
Two Remarkably Luminous Galaxy Candidates at z ≈ 10-12 Revealed by JWST
2022
The first few 100 Myr at z > 10 mark the last major uncharted epoch in the history of the universe, where only a single galaxy (GN-z11 at z ≈ 11) is currently spectroscopically confirmed. Here we present a search for luminous z > 10 galaxies with JWST/NIRCam photometry spanning ≈1–5 μm and covering 49 arcmin2 from the public JWST Early Release Science programs (CEERS and GLASS). Our most secure candidates are two MUV ≈ −21 systems: GLASS-z12 and GLASS-z10. These galaxies display abrupt ≳1.8 mag breaks in their spectral energy distributions (SEDs), consistent with complete absorption of flux bluewards of Lyα that is redshifted to =+z12.40.3 0.1and=+z10.40.5 0.4. Lower redshift interlopers su…
A Long Journey into the Investigation of the Structure–Dynamics–Function Paradigm in Proteins through the Activities of the Palermo Biophysics Group

An overview of the biophysics activity at the Department of Physics and Chemistry Emilio Segrè of the University of Palermo is given. For forty years, the focus of the research has been on the protein structure–dynamics–function paradigm, with the aim of understanding the molecular basis of the relevant mechanisms and the key role of solvent. At least three research lines are identified; the main results obtained in collaboration with other groups in Italy and abroad are presented. This review is dedicated to the memory of Professors Massimo Ugo Palma, Maria Beatrice Palma Vittorelli, and Lorenzo Cordone, which were the founders of the Palermo School of Biophysics. We all have been, directl…
Electrical two-qubit gates within a pair of clock-qubit magnetic molecules
2022
Enhanced coherence in HoW$_{10}$ molecular spin qubits has been demonstrated by use of Clock Transitions (CTs). More recently it was shown that, while operating at the CTs, it was possible to use an electrical field to selectively address HoW$_{10}$ molecules pointing in a given direction, within a crystal that contains two kinds of identical but inversion-related molecules. Herein we theoretically explore the possibility of employing the electric field to effect entangling two-qubit quantum gates among two neighbouring CT-protected HoW$_{10}$ qubits within a diluted crystal. We estimate the thermal evolution of $T_1$, $T_2$, find that CTs are also optimal operating points from the point of…

Vanadium Modulates Proteolytic Activities and MMP-14-Like Levels during Paracentrotus lividus Embryogenesis
2022
The increasing industrial use of vanadium (V), as well as its recent medical use in various pathologies has intensified its environmental release, making it an emerging pollutant. The sea urchin embryo has long been used to study the effects induced by metals, including V. In this study we used an integrated approach that correlates the biological effects on embryo development with proteolytic activities of gelatinases that could better reflect any metal-induced imbalances. V-exposure caused morphological/morphometric aberrations, mainly concerning the correct distribution of embryonic cells, the development of the skeleton, and the embryo volume. Moreover, V induced a concentration change …
Extracellular vesicles from Trypanosoma cruzi-dendritic cell interaction show modulatory properties and confer resistance to lethal infection as a ce…
2022
Extracellular vesicles (EVs) include a heterogeneous group of particles. Microvesicles, apoptotic bodies and exosomes are the most characterized vesicles. They can be distinguished by their size, morphology, origin and molecular composition. To date, increasing studies demonstrate that EVs mediate intercellular communication. EVs reach considerable interest in the scientific community due to their role in diverse processes including antigen-presentation, stimulation of anti-tumoral immune responses, tolerogenic or inflammatory effects. In pathogens, EV shedding is well described in fungi, bacteria, protozoan and helminths parasites. For Trypanosoma cruzi EV liberation and protein compositio…

Two-photon optical shielding of collisions between ultracold polar molecules
2022
We propose a method to engineer repulsive long-range interactions between ultracold ground-state molecules using optical fields, thus preventing short-range collisional losses. It maps the microwave coupling recently used for collisional shielding onto a two-photon transition, and takes advantage of optical control techniques. In contrast to one-photon optical shielding [Phys. Rev. Lett. 125, 153202 (2020)], this scheme avoids heating of the molecular gas due to photon scattering. The proposed protocol, exemplified for 23Na39K, should be applicable to a large class of polar diatomic molecules.
Intensity and persistence of water repellency at different soil moisture contents and depths after a forest wildfire
2022
Abstract The Mediterranean mixed coniferous and broad-leaved forest of Moarda (Palermo) was affected by a large wildfire in summer 2020. In spring 2021, burned and unburned loam soil sites were sampled and the water drop penetration time (WDPT) and ethanol percentage (EP) tests applied to assess the influence of wetting-drying processes and soil water content on post-fire soil water repellency (SWR) as well as its vertical distribution. According to the WDPT test, the surface layer of the natural unburned soils was severely hydrophobic at intermediate soil water contents roughly corresponding to wilting point and SWR reduced either for very dry conditions (air- or oven-dried conditions) or …
Protection from fishing improves body growth of an exploited species
2022
Hunting and fishing are often size-selective, which favours slow body growth. In addition, fast growth rate has been shown to be positively correlated with behavioural traits that increase encounter rates and catchability in passive fishing gears such as baited traps. This harvest-induced selection should be effectively eliminated in no-take marine-protected areas (MPAs) unless strong density dependence results in reduced growth rates. We compared body growth of European lobster ( Homarus gammarus ) between three MPAs and three fished areas. After 14 years of protection from intensive, size-selective lobster fisheries, the densities in MPAs have increased considerably, and we demonstrate t…
The Association of Self-Reported Birthweight with Lung Function and Respiratory Diseases: Results from a Multi-Centre, Multi-Case Control Study in It…
2022
Early life conditions are associated with lung function and the development of respiratory and non-respiratory illnesses. The relationship with birthweight (BW), however, is conflicting. We examined associations of self-reported BW with lung function and the development of respiratory and also non-respiratory diseases within the GEIRD (Gene–Environment Interaction in Respiratory Diseases) project, an Italian multi-centre, multi-case control study involving cases of COPD, asthma, allergic rhinitis and controls. Multinomial logistic regression was performed with case/control status as response variable; BW as main determinant; and adjusting for sex, age and smoking status. Of the 2287 p…
Signal dimension estimation in BSS models with serial dependence
2022
Many modern multivariate time series datasets contain a large amount of noise, and the first step of the data analysis is to separate the noise channels from the signals of interest. A crucial part of this dimension reduction is determining the number of signals. In this paper we approach this problem by considering a noisy latent variable time series model which comprises many popular blind source separation models. We propose a general framework for the estimation of the signal dimension that is based on testing for sub-sphericity and give examples of different tests suitable for time series settings. In the inference we rely on bootstrap null distributions. Several simulation studies are…
Developmental Enamel Defects in Children from the Southern Region of Ecuador
2022
Developmental defects of enamel (DDEs) are widely observed in children and are related to the appearance of dental caries, malocclusion, tooth sensitivity, and unfavorable esthetic conditions. The objective of this cross-sectional study was to determine the prevalence and distribution of enamel defects present in children aged 6 to 12 years in the provinces located in southern Ecuador. A total of 1606 schoolchildren were examined under the World Health Organization criteria for diagnosis of DDEs. The results are presented using percentage frequency measures and chi-square associations. Some types of DDEs were presented by 50% of the schoolchildren, mainly diffuse opacity, with no statistica…

Experimental introgression in Drosophila : Asymmetric postzygotic isolation associated with chromosomal inversions and an incompatibility locus on th…
2022
Interspecific gene flow (introgression) is an important source of new genetic variation, but selection against it can reinforce reproductive barriers between interbreeding species. We used an experimental approach to trace the role of chromosomal inversions and incompatibility genes in preventing introgression between two partly sympatric Drosophila virilis group species, D. flavomontana and D. montana. We backcrossed F1 hybrid females from a cross between D. flavomontana female and D. montana male with the males of the parental species for two generations and sequenced pools of parental strains and their reciprocal 2nd generation backcross (BC2mon and BC2fla) females. Contrasting the obser…

Type-2 intuitionistic fuzzy TODIM for intelligent decision-making under uncertainty and hesitancy
2022
AbstractThe classical TODIM considers the crisp numbers to handle the information. However, in a real-world applicative context, this information is bounded by noise and vagueness and hence uncertain. There are wide range of works in the literature which utilizes fuzzy sets to handle the uncertainty in the various dimensions. However, there is a constraint of hesitancy in such decision-making problems due to the involvement of various decision-makers. Also, in the TODIM method, decision-maker’s bounded rationality and psychological behavior are also taken into consideration which adds up the hesitation and considers the problem with higher dimension of uncertainty. There are various applica…

“Without social there is no health”: Social work perspectives in multidisciplinary healthcare
2022
The pandemic has not just affected the health sphere: strong social effects of the emergency have added to the health risk, stressing on social relations and the deterioration of people's living conditions, and making those who are already fragile more fragile. Notwithstanding, during the emergency following the COVID-19 pandemic the attention was focused, indeed understandably, on the health aspects, widening the already existing misalignment between the health interventions and the social ones. Emergency oriented efforts and resources more toward a clinical care approach (cure) than toward support for the social and the inclusion aspects (care). Reflecting on the specific area of health c…
Isotopic Niche and Trophic Position of the Invasive Portunid Portunus segnis Forskål, (1775) in Elounda Bay (Crete Island, Eastern Mediterranean)
2022
There is a growing recognition that an advanced understanding of the trophic characteristics of an invasive consumer can provide important information on its ecological impact. In recent years, the blue swimming crab Portunus segnis, one of the earliest Lessepsian invaders, has considerably expanded its distribution range in the Mediterranean Sea, yet, its trophic habits in invaded areas remain scarcely investigated. In this study, we used carbon and nitrogen stable isotopes analysis (SIA) to determine the trophic position and isotopic niche of the crab compared with other representatives of the flora and fauna occurring in Elounda Bay (Crete). P. segnis showed a trophic position of 3.9, hi…

Does forming a nuclear family increase religiosity? Longitudinal evidence from the British Household Panel Survey
2022
Abstract This study investigates how far the nuclear family—in terms of entering cohabitation and marriage and having a first and second child—affects religious salience, religious attendance, and activity in religious organizations. Previous research has shown that religious individuals are more likely to marry, and have higher fertility, than non-religious individuals. Less is known about how far the nuclear family also affects religiosity. This study presents longitudinal evidence on how religious factors change within the life-course of individuals after entering cohabitation or marriage and after having a first or second child in up to 14 waves of the British Household Panel Survey col…

Photostability assessment of natural pyrethrins using halloysite nanotube carrier system
2022
Natural pyrethrins are one of the most used pesticides and insect repellents employed for domestic or agronomic use. However, they are highly hydrophobic and suffer from insolubility in water media and ready decomposition by photochemical, and oxidative actions. These aspects hamper their long-term storage and applicability. Herein, we report the synthesis and characterization of a nanomaterial based on the loading of pyrethrum extract (PE) into natural, low-cost, and eco-compatible halloysite nanotubes (Hal). The Hal/PE nanomaterial was thoroughly characterized, and the morphology was imaged by TEM and SEM investigations. Release experiments showed a slow release of pyrethrins from the car…
Nobiletin and xanthohumol counteract the TNFα-mediated activation of endothelial cells through the inhibition of the NF-κB signaling pathway.
2022
Angiogenesis, a process characterized by the formation of new blood vessels from pre-existing ones, is a crucial step in tumor growth and dissemination. Given the ability of tumors to interfere with multiple or different molecular pathways to promote angiogenesis, there is an increasing need to therapeutically block tumor progression by targeting multiple antiangiogenic pathways. Natural polyphenols present health-protective properties, which are likely attributed to their ability to activate multiple pathways involved in inflammation, carcinogenesis, and angiogenesis. Recently, increased attention has been addressed to the ability of flavonoids, the most abundant polyphenols in the diet, t…
Organized interests in post-communist policy-making: a new dataset for comparative research
2022
AbstractThis article familiarizes readers with the international research project ‘The Missing Link: Exploring Organized Interests in Post-Communist Policy-Making’ (OrgIntCEE). The project team has focused on how populations of organized interests in the region have evolved, how they interact with state institutions as well as the group-specific characteristics driving access to policy-makers. The project also explores how Europeanization has affected post-communist interest groups as well as other factors contributing to their “coming-of-age.” We provide a comprehensive overview of the population ecology and survey datasets, while shedding light on the challenges during the data collection…
The asymptotics of the area-preserving mean curvature and the Mullins–Sekerka flow in two dimensions
2022
AbstractWe provide the first general result for the asymptotics of the area preserving mean curvature flow in two dimensions showing that flat flow solutions, starting from any bounded set of finite perimeter, converge with exponential rate to a finite union of equally sized disjoint disks. A similar result is established also for the periodic two-phase Mullins–Sekerka flow.
Brief Communication – ALARM: an innovative protocol of educating on seismic risk perception, and its assessment
2022
Abstract. The effectiveness of risk mitigation also depends on how well-prepared and informed society is about the risk itself. The younger generation plays a key role in the scientific awareness of society, representing both the future of society and a conduit to reach and educate their families. We developed a didactic experience, based on Serious Games, dedicated to seismic risk that was tested and, then, implemented during the whole COVID-19 pandemic. Before the start and at the end of any of these activities, an evaluation phase was carried out to assess the learning experience and the effectiveness of the science communication technique.
