Aim To evaluate the effectiveness of a professional identity promotion strategy (PIPS) on nursing students' professional identity and resilience. Methods This study was a quasi‐experimental study with a random cluster sample of 103 sophomore undergraduate nursing students. One hundred students answered the questionnaires at both baseline and follow‐up (51 of 53 in the intervention group and 49 of 50 in the control group). Intervention and control groups underwent 5 months PIPS and standard professional education from May 2 to September 27, respectively. Participants completed the professional identity questionnaire for nursing students (PIQNS) and Connor–Davidson resilience scale (CD‐RISC). Data were collected at baseline (T0), after the intervention (T1) and 3 months after the intervention (T2), and analyzed using the Chi‐squared test, Fisher's exact test, and repeated‐measures analysis of variance. Results There were no significant differences between the two groups ( p > .05) regarding demographic questions, professional identity, or resilience at baseline ( p > .05). Significant differences were found in professional identity between groups ( p < .001), measurement times ( p = .026), and in the interaction between groups and measurement times ( p = .018) from T0 to T2. Significant differences were found in resilience between groups ( p < .001), measurement times ( p = .007), and in the interaction between groups and measurement times ( p = .035) from T0 to T2. Conclusions The PIPS program improved nursing students' professional identity and resilience. Further long‐term effectiveness of the program needs to be tested with implementation through various forms of mobile technology.

Magnesium alloy is very attractive in many industrial applications due to its low density. The structure-property relationships of the magnesium alloy under quasi-static loading have been extensively investigated. However, the dynamic behavior, particularly the mechanism of high-rate plastic deformation, of the magnesium alloy requires more in-depth investigations. In this paper, the effect of aging treatment on the quasi-static and dynamic properties of a typical rare earth Mg-Gd-Y magnesium alloy is investigated. In particular, the plastic deformation mechanism under dynamic compression loading is discussed. Split Hopkinson Pressure Bar (SHPB) was used to carry out dynamic compression tests with controllable plastic deformation by using stopper rings. The experimental results demonstrate that both static and dynamic properties of the Mg-Gd-Y alloy vary under various aging treatment conditions (under-aged, peak-aged and over-aged conditions), due to two different kinds of second phases: remnant micro size phase from solid solution treatment and nano precipitation from aging treatment. The results of microstructure characterization and statistic analysis of the metallographic phase are presented. The area fraction of the twinned grains increases due to aging treatment and dynamic loading. The main plastic deformation mechanism of the rare earth Mg-Gd-Y magnesium alloy is possibly dislocation slip, rather than twinning for the conventional AZ31 magnesium alloy under high strain rate loading.
