A phenomenological theory of nonphotochemical laser induced nucleation

Our analysis of the experimental data related to nonphotochemical laser induced nucleation in solutions leads to the inevitable conclusion that the phase transformation is initiated by particles that are metallic in nature. This conclusion appears paradoxical because the final products are dielectric crystals. We show that the experimental results are well accounted for by the theory of electric field induced nucleation of metallic particles that are elongated in the direction of the field. However, new physical and chemical insights are required to understand the structure of the metallic precursor particles and the kinetics of subsequent dielectric crystallization.Comment: 5 pages 4 figure

Development and Testing of the Quality Improvement Self-efficacy Inventory

Quality improvement is paramount for patient safety. Leading change for quality improvement requires nurses with knowledge and skills beyond the clinical management of patients. In this study, staff nurses working in hospitals throughout Alabama were asked via an online survey to rate their quality improvement knowledge and skills using the new 10-item Quality Improvement Self-Efficacy Inventory (QISEI) and their perceptions of the nursing work environment using the Practice Environment Scale of the Nursing Work Index. Nurses (N = 886) rated the basic quality improvement items higher than the more advanced items. Several nurse characteristics and the nursing work environment were associated with nurses’ ratings of their quality improvement knowledge and skills. Educators and administrators in health care organizations can use QISEI to gauge their nurses’ knowledge and skills and then develop continuous professional development opportunities aimed at improving quality and safety competencies
