This study examines interpersonality and audience awareness of initial greetings and leave-taking formulae in 1,041 e-mails (523 Finnish, 518 Swedish) written by Finnish (n = 222) and Swedish (n = 174) language learners in basic education, secondary education and at university level in Finland. The results reveal that there are certain communicative differences between the two groups. The e-mails contain different levels of formality: Swedish learners use more initial greetings and their messages are slightly more coherent than those of Finnish learners. The initial greeting hei/hej is commonly used in different contexts, regardless of the language. Learners’ audience awareness is indicated…

In-beam spectroscopic study of $^{244}$Cf
2018
The ground-state rotational band of the neutron-deficient californium ( Z = 98 ) isotope 244 Cf was identified for the first time and measured up to a tentative spin and parity of I π = 20 + . The observation of the rotational band indicates that the nucleus is deformed. The kinematic and dynamic moments of inertia were deduced from the measured γ -ray transition energies. The behavior of the dynamic moment of inertia revealed an up-bend due to a possible alignment of coupled nucleons in high- j orbitals starting at a rotational frequency of about ℏ ω = 0.20 MeV . The results were compared with the systematic behavior of the even-even N = 146 isotones as well as with available theoretical c…
Shape coexistence in the odd-odd nucleus 98Y : the role of the g9/2 neutron extruder
2017
Excited states in 98Y, populated in neutron-induced fission of 235U and in spontaneous fission of 248Cm and 252Cf, have been studied by means of γ spectroscopy using the Lohengrin fission-fragment separator at ILL Grenoble and the EXILL, Eurogam2, and Gammasphere Ge arrays. Two new isomers have been found in 98Y: a deformed one with T1/2 = 180(7) ns and a rotational band on top of it, and a spherical one with T1/2 = 0.45(15)μs, analogous to the 8+ isomer in 96Y, corresponding to the (νg7/2,πg9/2)8+ spherical configuration. Using the JYFLTRAP Penning trap, an accurate excitation energy of 465.7(7) keV has been determined for the 2.36-s isomer in 98Y. This result and the studies of excited le…
Prompt and delayed spectroscopy of 203At : Observation of a shears band and a 29/2+ isomeric state
2018
Using fusion-evaporation reactions, a gas-filled recoil separator, recoil-gating technique and recoil-isomer decay tagging technique we have extended the level scheme of 203 At ( N = 118 ) significantly. We have observed an isomeric [ τ = 14.1 ( 3 ) μ s ] state with a spin and parity of 29 / 2 + . The isomeric state is suggested to originate from the π ( h 9 / 2 ) ⊗ ∣ ∣ 202 Po ; 11 − ⟩ coupling, and it is depopulated through 286 keV E 2 and 366 keV E 3 transitions. In addition, we have observed a cascade of magnetic-dipole transitions which is suggested to be generated by the shears mechanism. peerReviewed
Autonomy and Cooperation in Federalizing Models of Cultural Policy. Comparative Analysis of the Cases of Germany, USA, Canada, Switzerland, United Ki…
2018
Desde los años ochenta diversas investigaciones han profundizado en la comparación de los diversos modelos de las políticas culturales nacionales. Asimismo, el interés por la descentralización cultural y el reconocimiento de la diversidad cultural y nacional ha crecido en paralelo a la importancia de la acción cultural pública de las regiones y las municipalidades. Sin embargo, no se han desarrollado estudios que permitan comparar de forma sistemática la relación entre los modelos de federalismo y los modelos de política cultural de un Estado. Este trabajo persigue cubrir este vacío realizando una comparativa de seis países federales o casi federales que han destacado en su desarrollo de po…
Isomeric 13/2+ state in 201Fr
2020
We have identified an isomeric state in 201Fr for which we propose a spin and parity of 13/2 +, and interpret it as arising from the π(i13/2 ) configuration. A half-life of 720(40) ns was measured, corresponding to B(M2) = 0.17(2) W.u., in good agreement with those of other 13/2 + → 9/2 − [π(i13/2 ) → π(h9/2 )] transitions observed in other nuclei in the region. The nuclei of interest were produced in a fusion-evaporation reaction and their decay properties were investigated using the GREAT spectrometer at the focal plane of the RITU gas-filled recoil separator. peerReviewed
Fine structure in the α decay of high-spin isomers in 155Lu and 156Hf
2018
Fine structure in the α decay of high-spin isomers in 155Lu(25/2−) and 156Hf (8+) has been studied for the first time using αγ -coincidence analysis. Three new α decays from 155Lu(25/2−) and two from 156Hf (8+) have been identified, populating seniority s > 1 states in the N = 82 nuclei 151Tm and 152Yb, respectively. The reduced hindrance factors of the α decays support the previous configuration assignments of the populated states. This is the first observation of states with excitation energy greater than 1.5 MeV being populated following α decay in nuclei outside of the 208Pb region. peerReviewed
Lifetime measurements of lowest states in the π g7/2 ⊗ νh11/2 rotational band in 112I
2018
A differential-plunger device was used to measure the lifetimes of the lowest states in the πg7/2 ⊗ νh11/2 rotational band in doubly odd 112I with the 58Ni(58Ni, 3pn) reaction. A differential decay curve method was performed using the fully shifted and degraded γ -ray intensity measurements as a function of target-to-degrader distance. The lifetimes of the lowest three states in the πg7/2 ⊗ νh11/2 band in 112I were measured to be 124(30), 130(25), and 6.5(5) ps, respectively. As the lifetimes of successive excited states in a rotational band are expected to decrease with increasing excitation energy, these measurements suggest that the order of the transitions in the established band in 112…
