This study aims to explore the formation mechanism of aerodynamic noise of a high-speed maglev train and understand the characteristics of dipole and quadrupole sound sources of the maglev train at different speed levels.

Based on large eddy simulation (LES) method and Kirchhoff–Ffowcs Williams and Hawkings (K-FWH) equations, the characteristics of dipole and quadrupole sound sources of maglev trains at different speed levels were simulated and analyzed by constructing reasonable penetrable integral surface.

The spatial disturbance resulting from the separation of the boundary layer in the streamlined area of the tail car is the source of aerodynamic sound of the maglev train. The dipole sources of the train are mainly distributed around the radio terminals of the head and tail cars of the maglev train, the bottom of the arms of the streamlined parts of the head and tail cars and the nose tip area of the streamlined part of the tail car, and the quadrupole sources are mainly distributed in the wake area. When the train runs at three speed levels of 400, 500 and 600 km·h⁻¹, respectively, the radiated energy of quadrupole source is 62.4%, 63.3% and 71.7%, respectively, which exceeds that of dipole sources.

This study can help understand the aerodynamic noise characteristics generated by the high-speed maglev train and provide a reference for the optimization design of its aerodynamic shape.

Innovation is one of the most important foundations on which to create and sustain competitive advantages in companies, but at the individual level, employee innovative behavior has recently been jeopardized by the situation caused by the COVID-19 pandemic (e.g. changes in workplaces, employee interaction, motivation). This study analyzes wellness programs and actions through which organizations have tried to adapt to the new situation caused by COVID-19 and their effect on employee innovation behavior.

Structural equation modeling by means of the partial least squares technique was used to test the study's hypotheses after collecting survey data from Spanish companies, providing evidence that wellness programs and measures to deal with COVID-19 through perceived organizational support and affective commitment encourage employee innovation behavior.

The results suggest that efforts developed by firms focused on employee well-being to overcome difficulties caused by the pandemic strengthen innovative behaviors by means of intrinsic motivation based essentially on personal commitment. Theoretical and practical implications of the findings are discussed by the paper's authors.

This paper corroborates and extends previous research regarding wellness programs, perceived organization support and affective commitment. It provides a comprehensive model of relationships that predicts employee innovative behavior. It analyzes the influence of enterprise wellness programs based on protective COVID-19 measures.

Upon graduating from university, many engineers will work in new product development and/or technology adoption for continuous improvement and production optimization. These jobs require employees to be cognizant of ethical practices and implications for design. However, little engineering coursework, outside the traditional ABET (Accreditation Board for Engineering and Technology) required Engineering Ethics course, accounts for the role of ethics within this process. Because of this, engineering students have few learning opportunities to practice and reflect on ethical decision-making.

This paper highlights one approach to integrating ethics into an engineering course (outside of engineering ethics). Specifically, the study is implemented within a five-week module with a focus on big data ethics, as part of a Supply Chain Management Technology course (required for Industrial Engineering Technology majors), using metacognition as the core assessment.

Four main themes were identified through the qualitative data analysis of the metacognitive reflections: (1) overreliance on content knowledge, (2) time management skills, (3) career connections and (4) knowledge extensions.

Three notable points emerged which contribute to the literature. First, this study showcased one example of how an ethics module can be integrated into an engineering course (other than Engineering Ethics). Second, this study demonstrated how metacognitive reflections can be used to reinforce student self-awareness of the learning process and connections to big data ethics in the workplace. Finally, this study exhibited how metacognitive reflection assignments can be deployed as a teaching and learning assessment tool, providing an opportunity for the instructor to make immediate changes as needed.

The purpose of this paper is to assess previous research on conditions for managers’ learning and development in daily work practices and how such conditions may influence their sustainability and also to propose a concept and a heuristic model that reconceptualizes and expands on the theoretical foundations generated in previous studies of managers’ learning and development at work.

This paper is based on an integrative literature review. The literature search identified 1,403 unique studies. Nine qualitative and seven quantitative studies met the relevance and quality criteria and were included in the review.

The results of the review found associations between managers’ learning conditions, career opportunities, individual engagement and sustainability. However, the small amount of empirical data used in the reviewed studies and the cross-sectional design of the studies make it difficult to establish the nature of the relationship between different variables.

The results of this paper show that managers need to care for and take advantage of opportunities for their own development and not only function as creators of their employees’ development. Employers should keep in mind that the development environment includes managers and employees.

This paper contributes with an original concept of managers’ development environments and a conceptual model that integrates theory with results from the included studies. Based on the model, propositions that may serve as an agenda for future research are formulated.

This paper aims to study and measure the level of the psychological well-being, of the employees in IT/ITES organizations and to find out whether the psychological well-being (PWB), of the IT/ITES employees significantly varies with their socio-economic and demographic profiles.

Study was conducted among the employees in IT/ITES companies in Infopark, a cluster of companies, in Cochin. There are 30,000 employees estimated as working in different companies in Infopark. Considering the size of the population, the researcher targeted 1200 sample respondents (covering 4% of the population) and distributed 1400 questionnaires to IT/ITES employees of different companies in Infopark. The response rate was 78%, hence, the researcher could get back 1092 filled questionnaires. However, out of 1092, filled questionnaires, 24 questionnaires (2.20%) were found to be either incomplete or with mistakes and hence not in usable nature. These were eliminated from the final sample. The final sample for this study is (1092–24) thus taken as 1068 IT/ITES employees (3.56%) in Infopark, Kochi. psychological well-being (PWB) of the employees in IT/ITES organizations was measured using the PWB scale by Ryff (1989). Data analysis was done using parametric tests like, independent sample test and analysis of variance.

The current study tries to explain the variation in PWB, of IT/ITES employees with respect to their socio-economic and demographic profiles. Based on the independent sample t-test and one-way ANOVA test results relating to H1a (gender), H1b (age), H1c (work-experience) and H1d (employment level) the overall hypothesis H1: PWB exhibited by the IT/ITES employees significantly varies with their socio-economic and demographic profiles is rejected. Hence it is concluded that PWB among IT/ITES employees do not significantly differ with respect to their socio-economic and demographic profile.

The study results may help the academia, trainers and researchers to identify new ways of improving PWB among employees. It will also help them to focus on training programmes, targeting toward the betterment of PWB. Policymakers' role is significant in promoting PWB among employees so as to ensure sustainable organizational performance.

The study will help managers to provide a conducive work place where employees are psychologically mature and carry positive attitude toward work, work environment and co-workers. Planned interventions are necessary to enhance team spirit, cooperation, cohesiveness and collaboration among employees.

With the study findings new psychosocial interventions could be offered to the IT/ITES professionals in the form of training and personality development programmes. This will directly influence team effectiveness among employees.

A study on PWB has not yet been done among the Infopark employees. Thus, a study to assess the level of PWB carried out among IT/ITES professionals in Kochi is quite a new approach. A study of this nature is believed to help employers take measures for enhancing the PWB which will help to improve the team performance and thus the performance of the company as a whole.
