Prompt and delayed spectroscopy of 199At
2010
The neutron-deficient nucleus At199 has been studied through γ-ray and electron spectroscopy, using the recoil-decay tagging technique. Two experiments were conducted, using a gas-filled recoil separator with a focal-plane spectrometer alone and together with a germanium-detector array at the target position. The resulting level scheme for At199 includes a new isomer with a half-life of 0.80(5) μs and a spin and parity of (29/2+). The 13/2+ isomer, which de-excites via an M2 transition to the 9/2− ground state, was measured to have a half-life of 70(20) ns. Our earlier version of the level scheme for At197 has been updated as well. peerReviewed
Structure of 115Ag studied by β− decays of 115Pd and 115mPd
2012
The excited levels of 115Ag have been studied via the beta decay of 115Pd and 115Pdm. The beta-decay schemes for both states have been considerably extended, especially the scheme following the decay of 115Pdm which was practically unknown before this work. Transition intensities and log10 f t values are reported, which have been missing in the literature. A set of levels around 2 MeV has been found to be strongly populated by the beta decay of the ground state of 115Pd and is suggested to have a three-quasiparticle nature. The properties of excited levels have been compared with the level systematics of lighter neutron-rich silver isotopes, and new spin assignments as well as identificatio…
Candidate superdeformed band in 28Si
2012
Recent antisymmetrized molecular dynamics (AMD) calculations for 28Si suggest the presence of a superdeformed (SD) band with a dominant 24Mg + α clustering for its configuration, with firm predictions for its location and associated moment of inertia. This motivates a review of the experimental results reported in the literature with a particular focus on 24Mg(α,γ ) studies, as well as on α-like heavy-ion transfer reactions such as 12C(20Ne,α) 28Si. Combining this information for the first time leads to a set of candidate SD states whose properties point to their α-cluster structure and strong associated deformation. Analysis of data from Gammasphere allows the electromagnetic decay of thes…

Student Engagement and School Burnout in Finnish Lower-Secondary Schools: Latent Profile Analysis
2016
Self-ratings of behavioural engagement, cognitive engagement and school burnout were used in person-centred analyses to identify latent profiles among 2,485 Finnish lower-secondary school students. Three profiles were identified: high-engagement/low-burnout (40.6% of the sample), average-engagement/average-burnout (53.9%), and low-engagement/high-burnout (5.5%). Another sample of lower-secondary school students was used to validate the 3 profiles. The factors most strongly associated with the high-engagement/low-burnout profile of lower-secondary school students’ were high levels of support from teachers and family, good academic performance, and lack of truancy. The study indicated that te…
Ohjauksen palvelujärjestelyjen toimijoiden käsitykset johtamisesta ohjausverkostossa : matkalla verkostojohtamiseen?
2010
Ohjausverkosto on monisilmukkainen organisaatioiden sisäinen ja niiden rajapinnoille ulottuva verkosto. Ohjaus on tässä tutkimuksessa osallistava, oppimista ja elämänsuunnittelua edistävä palvelu. Muiden tukipalveluiden, kuten oppilas- ja opiskelijahuollon rinnalla ja kanssa se muodostaa verkostoituvat moniammatilliset ja monihallinnolliset palvelujärjestelyt. Tutkimuksessa tarkastellaan alueellisten ohjauksen toimijoiden käsityksiä ohjauksen palvelujärjestelyjen yhteistyön johtamisesta. Tulosten perusteella johtamisella luodaan palveluiden rakenteet, edistetään palveluprosesseja, tuetaan henkilöstön osaamisen kehittämistä ja jaksamista sekä tuotetaan yhteistyössä palveluita kaikille asiaka…
