Given that the relationship between proactive personality and turnover intention is not straightforward in the literature, the authors address two research questions focusing on the nursing profession: does proactive personality negatively influence nurses' turnover intention by alleviating their lack of professional recognition? And does a supervisor’s proactive personality act as a boundary condition for the mediating effects of the lack of professional recognition in the link between proactive personality and turnover intentions?

A moderated mediation model linking proactive personality and turnover intentions was developed and tested on a sample of 579 nurses in 88 work units in general hospitals in South Korea.

The results of multilevel path analysis reveal that proactive personality has a negative indirect relationship with turnover intention via lack of professional recognition. Additionally, the indirect relationship is strengthened when the supervisor’s proactive personality is low.

These findings provide valuable empirical evidence on the inconclusive relationship between proactive personality and turnover intention by highlighting the role of proactive personality in attenuating the influence of negative occupational factors. Moreover, proactive personality as a boundary condition for the aforementioned relationship was empirically examined.

The purpose of this study is to identify and assess the role of predictors to women’s economic empowerment (WEE). Moreover, the mediating role of digital banking usage (DBU) between financial literacy (FL) and WEE is empirically tested. The study also examines the moderation effect of educational level (EL) and employment sector (ES) on WEE.

Using a mixed-method approach, a comprehensive questionnaire was used to collect data of 482 women working in the formal ESs of Delhi-NCR. Partial least square structural equation modeling using SmartPLS-4 was used to test the explanatory and predictive power of the proposed model. This was followed by semi-structured interviews to collect qualitative data from 14 respondents.

The results present the following important findings: first, DBU, FL, women’s agency (WA) and workplace human resource policies (HR) significantly impact WEE, whereas government support (GS) and FL significantly impact DBU; second, DBU significantly mediates the relationship between FL and WEE; and third, ES significantly moderates the relationship between DBU and WEE.

This research also shares significant findings for practitioners and organizations by holistically identifying factors affecting WEE. These findings apply to both the human resource department of the employment sectors and the management of the banking sector.

The present study adds value to the scarce literature on the impact of DBU on WEE and highlights the mediating role of DBU along with the moderation effect of EL and ES. The study model incorporates novel constructs that impact WEE and offers new insights to various stakeholders in enhancing WEE. In addition, qualitative method was used to complement the quantitative findings.

This study examined whether officers’ perceptions of the effect of BWCs on procedural justice, police lawfulness, police legitimacy, compliance with police and law, and cooperation with police differed by type of law enforcement agency.

The data were collected from a survey administered to 152 police officers from State Police, City Police, University Police, and Sheriff’s Office.

The multivariate analyses found that City Police officers hold significantly more positive perceptions than University Police (on police legitimacy and cooperation with police), State Police (except for police lawfulness, on all other outcomes), and Sheriffs’ Office officers (on procedural justice and police legitimacy). Additionally, Sheriffs’ Office officers hold significantly more positive perceptions than University Police (on police legitimacy, cooperation with police, and compliance with police) and State Police (on police legitimacy, cooperation with police, compliance with police and law). No significant difference was found between University Police and State Police officers.

This is the first study that examines whether officers’ perceptions of the outcomes differ by type of law enforcement agency.

The article aims to establish whether the degree of aversion to inflation and the responsiveness to deviations from potential output have changed over time.

This paper assesses time variation in monetary policy rules by applying a time-varying parameter generalised methods of moments (TVP-GMM) framework.

Using monthly data until December 2022 for five inflation targeting countries (the UK, Canada, Australia, New Zealand, Sweden) and five countries with alternative monetary regimes (the US, Japan, Denmark, the Euro Area, Switzerland), we find that monetary policy has become more averse to inflation and more responsive to the output gap in both sets of countries over time. In particular, there has been a clear shift in inflation targeting countries towards a more hawkish stance on inflation since the adoption of this regime and a greater response to both inflation and the output gap in most countries after the global financial crisis, which indicates a stronger reliance on monetary rules to stabilise the economy in recent years. It also appears that inflation targeting countries pay greater attention to the exchange rate pass-through channel when setting interest rates. Finally, monetary surprises do not seem to be an important determinant of the evolution over time of the Taylor rule parameters, which suggests a high degree of monetary policy transparency in the countries under examination.

It provides new evidence on changes over time in monetary policy rules.

Permanent magnet synchronous spherical motors can have wide use in robotics and industrial automation. They enable three-DOF omnidirectional motion of their rotor. They are suitable for several applications, such as actuation in robotics, traction in electric vehicles and use in several automation systems. Unlike conventional synchronous motors, permanent magnet synchronous spherical motors consist of a fixed inner shell, which is the stator, and a rotating outer shell, which is the rotor. Their dynamic model is multivariable and strongly nonlinear. The treatment of the associated control problem is important.

In this paper, the multivariable dynamic model of permanent magnet synchronous spherical motors is analysed, and a nonlinear optimal (H-infinity) control method is developed for it. Differential flatness properties are proven for the spherical motors’ state-space model. Next, the motors’ state-space description undergoes approximate linearization with the use of first-order Taylor series expansion and through the computation of the associated Jacobian matrices. The linearization process takes place at each sampling instance around a time-varying operating point, which is defined by the present value of the motors’ state vector and by the last sampled value of the control input vector. For the approximately linearized model of the permanent magnet synchronous spherical motors, a stabilizing H-infinity feedback controller is designed. To compute the controller’s gains, an algebraic Riccati equation has to be repetitively solved at each time-step of the control algorithm. The global stability properties of the control scheme are proven through Lyapunov analysis. Finally, the performance of the nonlinear optimal control method is compared against a flatness-based control approach implemented in successive loops.

Due to the nonlinear and multivariable structure of the state-space model of spherical motors, the solution of the associated nonlinear control problem is a nontrivial task. In this paper, a novel nonlinear optimal (H-infinity) control approach is proposed for the dynamic model of permanent magnet synchronous spherical motors. The method is based on approximate linearization of the motor’s state-space model with the use of first-order Taylor series expansion and the computation of the associated Jacobian matrices. Furthermore, the paper has introduced a different solution to the nonlinear control problem of the permanent magnet synchronous spherical motor, which is based on flatness-based control implemented in successive loops.

The presented control approaches do not exhibit any limitations, but on the contrary, they have specific advantages. In comparison to global linearization-based control schemes (such as Lie-algebra-based control), they do not make use of complicated changes of state variables (diffeomorphisms) and transformations of the system's state-space description. The computed control inputs are applied directly to the initial nonlinear state-space model of the permanent magnet spherical motor without the intervention of inverse transformations and thus without coming against the risk of singularities.

The motion control problem of spherical motors is nontrivial because of the complicated nonlinear and multivariable dynamics of these electric machines. So far, there have been several attempts to apply nonlinear feedback control to permanent magnet-synchronous spherical motors. However, due to the model’s complexity, few results exist about the associated nonlinear optimal control problem. The proposed nonlinear control methods for permanent magnet synchronous spherical motors make more efficient, precise and reliable the use of such motors in robotics, electric traction and several automation systems.

The treated research topic is central for robotic and industrial automation. Permanent magnet synchronous spherical motors are suitable for several applications, such as actuation in robotics, traction in electric vehicles and use in several automation systems. The solution of the control problem for the nonlinear dynamic model of permanent magnet synchronous spherical motors has many industrial applications and therefore contributes to economic growth and development.

The proposed nonlinear optimal control method is novel compared to past attempts to solve the optimal control problem for nonlinear dynamical systems. Unlike past approaches, in the new nonlinear optimal control method, linearization is performed around a temporary operating point, which is defined by the present value of the system's state vector and by the last sampled value of the control inputs vector and not at points that belong to the desirable trajectory (setpoints). Besides, the Riccati equation which is used for computing the feedback gains of the controller is new, and so is the global stability proof for this control method. Compared to nonlinear model predictive control, which is a popular approach for treating the optimal control problem in industry, the new nonlinear optimal (H-infinity) control scheme is of proven global stability, and the convergence of its iterative search for the optimum does not depend on initial conditions and trials with multiple sets of controller parameters. It is also noteworthy that the nonlinear optimal control method is applicable to a wider class of dynamical systems than approaches based on the solution of state dependent Riccati equations (SDRE). The SDRE approaches can be applied only to dynamical systems which can be transformed into the linear parameter varying form. Besides, the nonlinear optimal control method performs better than nonlinear optimal control schemes, which use approximation of the solution of the Hamilton–Jacobi–Bellman equation by Galerkin series expansions. Furthermore, the second control method proposed in this paper, which is flatness-based control in successive loops, is also novel and demonstrates substantial contribution to nonlinear control for robotics and industrial automation.

This study examines the barriers and drivers to student-led mobilization for sustainability in higher education institutions (HEIs) across Canada. Findings indicate that the most common barrier to student mobilization was a lack of political opportunities and social capital. In response, the findings indicate that the primary drivers that student-led sustainability groups used to overcome barriers included: sharing framing perspectives to inspire and motivate action across campuses, using social networks to borrow and leverage social capital from other stakeholders, and impacting campus stakeholder behaviors resulting in the creation of a culture of sustainability. Social movement theories have been applied to the barriers and drivers to student-led action in order to provide a deeper understanding of how students mobilize on campuses. The findings suggest that while students may struggle to elicit policy changes across HEIs due to common barriers, their efforts can successfully shift the campus culture of sustainability. This study addresses an identified need for more literature investigating sustainability activism in higher education more broadly and more specifically fills a gap in our understanding of how student activism may contribute to social change.
