Brief Research Report: The Impact of a Utility-Value Intervention on Students’ Engagement

The present study investigated the impact of a utility-value intervention on students’ behavioral, cognitive, and emotional engagement. Students assigned to the intervention condition were required to write an essay to connect the course contents with their personal hobbies, interests, or goals three times during the course. The results showed that the students who completed all the intervention assignments behaviorally engaged more in the course (evaluated by continuous assignment submission), while those in the control condition became less engaged later in the course. Moreover, the students who completed the intervention assignments remained cognitively engaged even at the end of the course. We discussed how a utility-value intervention works on students’ engagement and practical implications for amplifying the effectiveness of a utility-value intervention.Goto T..

27Al-NMR Study on a square-Kagome lattice antiferromagnet

NMR study has been performed on an S = 1/2 antiferromagnet KCu6AlBiO4(SO4)5Cl on the square-Kagome lattice, which has three slightly inequivalent nearest-neighbor interactions. Because of the geometrical frustration inherited from triangles within the square kagome lattice and of the low dimensionality, a long range magnetic order is strongly suppressed; its absence has so far been confirmed in low temperatures down to dilution refrigerator region. 27Al-NMR spectra and the longitudinal relaxation time T1 were measured by a conventional pulsed spectrometer on powder sample under several magnetic fields between 3 and 10 T and in low temperatures down to 0.35 K. The NMR line width due to the inhomogeneous broadening increased with lowering temperatures and leveled off below 3 K, where FWHM reached the value as large as 0.1 T, implying that the ground state is magnetic one, consistent with previous reports. On the other hand, the longitudinal nuclear spin relaxation rate 1/T1 obeyed the Arrhenius law with the thermal activation energy {\Delta} = 2K at low temperatures, suggesting that a small gap is formed in the spin excitation spectrum.Comment: Hyperfine Interaction 2023, to appear in Interaction

Lepton electric dipole moments in supersymmetric type II seesaw model

AbstractWe study the lepton electric dipole moments in the framework of the supersymmetric type II seesaw model where the exchange of heavy SU(2)W triplets generates small neutrino masses. We show that the CP violating phase of the bilinear soft supersymmetry breaking term associated with the SU(2)W triplets contributes to lepton electric dipole moments mainly through threshold corrections to the gaugino masses at the seesaw scale. As a consequence, the ratio of the electric dipole moments of the muon and the electron is the same as the ratio of their masses in a wide region of parameter space
