Purpose: This study aimed to investigate the relationship between the expectations of unit-level nurses from nursing assistants (NAs), frequency of individual NAs' information-sharing behaviors with nurses, and the effect of NAs’ self-perceived roles on this relationship. NAs provide patient care along with nurses, and their information-sharing behaviors with nurses may be influenced by the expectations of the nurses. Methods: Nurses and NAs from 104 integrated community care (sub- and postacute) units were included in this Japanese cross-sectional study conducted from July to September 2018. Nurses' expectations from NAs and the NAs' self-perceived roles and information-sharing frequency were measured. Multilevel mediation analysis was performed for NAs’ information-sharing behaviors, such as expressing, asking, providing linguistic responses, and providing feedback. Results: Unit-level nurses' expectations from NAs were associated with the frequency of NAs' asking and responding behaviors with nurses (p < .05), mediated by the NAs' self-perceived roles. The frequency of NAs’ expressing behaviors and feedback were also associated with their self-perceived roles (p < .001). Conclusions: High expectations of unit-level nurses from NAs led to better perception by NAs of their roles and led to better information-sharing behaviors. Educating nurses on NAs’ roles may improve information-sharing between nurses and NAs that leads to safe and appropriate care to patients.

We have performed zero-field muon spin relaxation measurements in single-crystalline samplesof superconducting (SC) RbxFe2−ySe2 (Tc = 29 K) and non-SC RbxFe2−ySe2 in order to elucidatewhether there is difference in the magnetic states between SC and non-SC systems. In the SCsample, no temperature dependence of the muon spin polarization was observed at temperaturesbelow 40 K while a decrease in the spin polarization was observed in the non-SC sample withdecreasing temperature. This suggests that a new magnetically ordered state seems to develop inthe non-SC sample.
Phase Separation of Antiferromagnetism and Superconductivity in RbxFe2−ySe2 Observed by Using Rb NMR

We have carried out 87Rb NMR measurements on single crystals with and without the superconducting(SC) transition to clarify whether the SC and the antiferromagnetic (AFM) states aremicroscopically coexistent or just phase-separated in the Rb-intercalated iron-selenide RbxFe2−ySe2. The 87Rb NMR spectra observed at temperature below 300 K for these crystals are clearly separableinto two parts with different structures and widths. The broader spectrum can be explainedby the presence of a region with an AFM spin structure proposed by neutron scattering studies. The narrower spectrum in the crystal with the SC transition can be understood from the temperaturedependences of the spectral frequency-position and shape to stem from the SC region withTc = 30.8 K. Thus, we can clearly conclude that the superconductivity and the antiferromagnetismin the present system are phase-separated. Also, the crystal without the SC transition has twophase-separated regions with respective magnetic transitions at 500 and 50 K.
