In order to detect weld defects in laser welding T-joint of Al–Li alloy, a real-time X-ray image system is set up for quality inspection. Experiments on real-time radiography procedure of the weldment are conducted by using this system. Twin fillet welding seam radiographic arrangement is designed according to the structural characteristics of the weldment. The critical parameters including magnification times, focal length, tube current and tube voltage are studied to acquire high quality weld images. Through the theoretical and data analysis, optimum parameters are settled and expected digital images are captured, which is conductive to automatic defect detection.

Background Workplace climate is a great significant element that has an impact on nurses’ behavior and practice; moreover, nurses’ service behavior contributes to the patients’ satisfaction and subsequently to the long-term success of hospitals. Few studies explore how different types of organizational ethical climate encourage nurses to engage in both in-role and extra-role service behaviors, especially in comparing the influencing process between public and private hospitals. This study aimed to compare the relationship between the five types of ethical climate and nurses’ in-role and extra-role service behaviors in public and private hospitals. Methods This study conducted a cross-sectional survey on 559 nurses from China in May 2019. The questionnaire was distributed to nurses by sending a web link via the mobile phone application WeChat through snowball sampling methods. All participants were investigated using the Ethical Climate Scale and Service Behavior Questionnaire. SPSS 22.0 was used for correlation analysis, t-test, and analysis of variance test, and Mplus 7.4 was used for group comparison (p < .05). Results The law and code climate has a much greater influence on nurses’ in-role service behavior in private hospitals than on that in public hospitals (β = − 0.277; CI 95 % = [-0.452, − 0.075]; p < .01), and the instrumental climate has a stronger influence on nurses’ extra-role service behavior private hospitals than on that in public hospitals (β = − 0.352; CI 95 % = [-0.651, − 0.056]; p < .05). Meanwhile, the rules climate has a greater effect on nurses’ extra-role service behavior in public hospitals than it does in private hospitals (β = 0.397; CI 95 % = [0.120, 0.651]; p < .01). Conclusions As the relationship between the five types of ethical climate and nurses’ in-role and extra-role service behaviors in public and private hospitals were different, the strategies used to foster and enhance the types of ethical climate are various from public to private hospitals. The caring and instrumental climate are the key to promote extra-role service behavior for nurses in private hospitals. And the independent climate has a great effect on extra-role service behaviors for nurses in public hospitals.

PurposeEntrepreneurial passion has important implications for entrepreneurial success and psychological well-being. But their connections are complicated by the fact that three entrepreneurial passions (passion for inventing, passion for founding and passion for developing) can be combined differently according to their level and shape difference. A variable-centered approach cannot explain their relationship very well, by only focusing on the level difference and ignoring the different combination of entrepreneurial passion in subpopulations. The purpose of this study is to explore the function of entrepreneurial passion on entrepreneurial success and psychological well-being from a person-cantered approach.Design/methodology/approachIn this study, the authors conducted latent profile analyses to identify different configurations of different entrepreneurial passions (passion for inventing, passion for founding, passion for developing) on two samples of Chinese students and entrepreneurs. Then in the sample of Chinese entrepreneurs, the authors utilized the DCON command in Mplus to provide comparisons among the profiles on entrepreneurial success and psychological well-being.FindingsBased on identity theory, the authors found four entrepreneurial passion profiles across two samples—fully passionate, action-driven, interest-driven and dispassionate. Furthermore, the authors found that fully passionate entrepreneurs showed the highest level of entrepreneurial success, followed by action-driven, and then by interest-driven and dispassionate showed the lowest level. Action-driven entrepreneurs experienced the highest level of psychological well-being, followed by fully passionate entrepreneurs, then by interest-driven and dispassionate.Originality/valueThe results provide new insights into the nature and influence of entrepreneurial passion on entrepreneurial success and psychological well-being from a person-centered perspective.
