Precision 71Ga – 71Ge mass-difference measurement
2016
The 71Ga(νe, e−) 71Ge reaction Q value has been measured with the JYFLTRAP mass spectrometer at the IGISOL facility of the University of Jyv¨askyl¨a to Q = 232.443(93) keV. This value agrees with previous measurements, though it features a much higher accuracy. The Q value is being discussed in the context of the solar neutrino capture rate in 71Ga. peerReviewed
High-precision mass measurements for the isobaric multiplet mass equation atA= 52
2017
Masses of $^{52}$Co, $^{52}$Co$^m$, $^{52}$Fe, $^{52}$Fe$^m$, and $^{52}$Mn have been measured with the JYFLTRAP double Penning trap mass spectrometer. Of these, $^{52}$Co and $^{52}$Co$^m$ have been experimentally determined for the first time and found to be more bound than predicted by extrapolations. The isobaric multiplet mass equation for the $T=2$ quintet at $A=52$ has been studied employing the new mass values. No significant breakdown (beyond the $3\sigma$ level) of the quadratic form of the IMME was observed ($\chi^2/n=2.4$). The cubic coefficient was 6.0(32) keV ($\chi^2/n=1.1$). The excitation energies for the isomer and the $T=2$ isobaric analogue state in $^{52}$Co have been d…
Single-particle and collective excitations in the transitional nucleus 166Os
2021
The mean lifetimes of the lowest energy 2+, 8+ and 9− states in 166Os have been measured using the recoil distance Doppler-shift method in conjunction with a selective recoil-decay tagging technique. These measurements extend studies into the most neutron-deficient mass region accessible to current experimental methods. The B(E2; 2+ → 0+) = 7(2) W.u. extracted from these measurements is markedly lower than those observed in the heavier even-mass Os isotopes. The 8+ and 9− states yield reduced transition probabilities that are consistent with single-particle transitions. While these values may indicate a departure from collective structure, the level scheme and the underlying nuclear configu…
Aiuti di Stato all’interno di uno stesso gruppo societario: profili sostanziali e processuali
2022
The essay deals with a State aid case between companies belonging to the same corporate group. To clarify the concepts of ‘State resources’ and the misure imputable to the State, the essay suggests framing the concrete case within the framework of the so-called “in-house” company. This does not rule out the application of the private investor test in normal market conditions, which – if disregarded – can overcome the indistinction typical of “in-house” companies.
Measurement
2020
The basic idea of measurement is that objects exhibit an attribute for which questions like “do objects exhibit the attribute to the same degree or for any pair of them does one exhibit it more or less than the other?” make sense. It implies ordering objects that show an equal, a greater or lesser amount of one attribute, The notion of order is captured by the concept of a binary relation that is at least a weak order. Stevens (1946, 1951) classified four types of scales through which the assignment of objects to numbers can be achieved. These two approaches converge on the Representational Theory of Measurement, according to which it is the construction of functions from a set of data to a…
Dimension of projection : Marstrand's theorem
2022
Tässä tutkielmassa todistetaan Marstrandin projektiolause käyttäen apuna potentiaaliteoriaa. Projektiolauseen mukaan 2-ulotteisen Borel joukon ortogonaaliprojektion Hausdorffin dimensio on luvun 1 ja kyseisen Borel joukon dimension minimi melkein kaikkiin eri suuntiin. Intuitiivisesti lause kertoo, että joukon varjon dimensio on suurin mahdollinen. Marstrandin projektiolauseen todistamiseksi tutkielmassa rakennetaan teoria alkaen yleisen mittateorian perustuloksista. Mittateorian pohjalta määritellään Hausdorffin mitta, jonka avulla määritellään joukon Hausdorffin dimensio. Intuitiivisesti Hausdorffin dimensio kuvaa joukon geometrista kokoa ja se on yksikäsitteinen jokaiselle joukolle. Haus…
Evaluating the Dimensionality of the Sociocultural Adaptation Scale in a Sample of International Students Sojourning in Los Angeles: Which Difference…
2022
The Sociocultural Adaptation Scale (SCAS) measures the degree of sociocultural competence in new cultural settings, and, despite its popularity, research aiming at evaluating its dimensionality is lacking and has incongruent results. Moreover, the dimensionality of the scale has been mainly tested on different samples adjusted to Eastern culture. We administered the SCAS to 266 international students sojourning in Los Angeles to test which underlying dimensionality emerges if the measure is used to assess sociocultural adaptation to Western culture, also verifying its measurement invariance across sex. Findings from EFA showed a three-factor solution: Diversity Approach, Social Functioning,…
Measuring Health Literacy in Childhood and Adolescence with the Scale Health Literacy in School-Aged Children – German Version : The Psychometric Pro…
2022
Abstract. Health literacy can help explain health inequalities in childhood and adolescence. However, suitable instruments for assessing health literacy in this age group are rare, especially in the German-speaking countries. One economical measure is the 10-item Health Literacy in School-Aged Children (HLSAC) scale, developed and reviewed as part of the WHO Child and Adolescent Health Study (HBSC, Health Behavior in School-Aged Children). In the present study, we tested dimensionality, measurement invariance, and associations with health-related measures of the German version of the scale (HLSAC–German), using data from the 2018 national German HBSC study ( N = 4,347 students aged 11, 13,…
Assessment of students’ agency in Finnish and Spanish university courses: Analysis of measurement invariance
2023
This study reports on the measurement invariance of the Agency of University Students Scale in data consisting of Finnish and Spanish university students (n = 645) and presents cross-national findings on student agency assessment. Multigroup confirmatory factor analysis confirmed the metric invariance for 10 factors, which allows comparisons of covariance structures and correlation analyses, and can, for example, be used to examine background factor effects on agency across groups. At least partial scalar invariance was confirmed for six factors, allowing comparisons of mean values between Finnish and Spanish students. Differences were found in the experiences of personal and relational res…
Psychometric Comparisons of Benevolent and Corrective Humor across 22 Countries: The Virtue Gap in Humor Goes International
2018
Recently, two forms of virtue-related humor, benevolent and corrective, have been introduced. Benevolent humor treats human weaknesses and wrongdoings benevolently, while corrective humor aims at correcting and bettering them. Twelve marker items for benevolent and corrective humor (the BenCor) were developed, and it was demonstrated that they fill the gap between humor as temperament and virtue. The present study investigates responses to the BenCor from 25 samples in 22 countries (overall N = 7,226). The psychometric properties of the BenCor were found to be sufficient in most of the samples, including internal consistency, unidimensionality, and factorial validity. Importantly, benevolen…
