Magnetorheological elastomers (MREs) are in demand in the field of high-tech microindustries and nanoindustries such as biomedical applications and soft robotics due to their exquisite magneto-sensitive response. Among various MRE applications, programmable actuators are emerging as promising soft robots because of their combined advantages of excellent flexibility and precise controllability in a magnetic system. Here, we present the development of magnetically programmable soft magnetic microarray actuators through field-induced injection molding using MREs, which consist of styrene-ethylene/butylene styrene (SEBS) elastomer and carbonyl iron powder (CIP).

This study investigates the complex interplay between organizationally prescribed perfectionism (OPP), job insecurity, counterproductive work behavior (CWB), and self-efficacy in learning artificial intelligence (AI) in the context of modern organizations. Based on several theories, the current research suggests and tests a moderated mediation model. Using a three-wave time-lagged design with data collected from 412 workers across various South Korean corporations, we examine how OPP influences CWB both directly and indirectly through job insecurity, and how self-efficacy in AI learning moderates the OPP-job insecurity link.

As corporate social responsibility (CSR) has progressively ascended to prominence among academics and industry professionals, numerous studies have embarked on examining its impact on employees' perceptions, attitudes, and behaviors. Notwithstanding, the current body of research has predominantly overlooked the influence of CSR on employees' mental health, encompassing depression, anxiety, and burnout. In order to acknowledge the critical role of employee mental health within an organization, our exploration is focused on discerning the effect of CSR on depressive states.

Using a variety of theoretical foundations, this paper examines the association between corporate social responsibility (CSR) and employees' knowledge-sharing behavior, investigating the sequential mediation role of perceived organizational support and organizational commitment as well as the moderating role of ethical climate. Hypotheses were formulated to address both the sequential mediation effect of perceived organizational support and organizational commitment on the link between CSR and knowledge-sharing and the moderation effect of ethical climate on the relationship between CSR and perceived organizational support. In order to mitigate the problems of potential common method bias, data were gathered from a sample of 204 South Korean employees at three distinct time points.

Swift social and economic environmental changes such as those associated with the COVID-19 pandemic have led to decreased job security. Although numerous previous studies have examined the influence of job insecurity on employee perceptions, attitudes, and behaviors, the link between job insecurity and negative behavior and its underlying or intermediating mechanisms remain underexplored. The significance of an organization's positive behaviors, which fall under the umbrella of corporate social responsibility (CSR), also deserves more attention.

Considering the importance of safety behavior, the current study investigates the relationship between CSR and safety behavior. To be specific, we delve into the underlying mechanism and its contingent factor of the association. This paper proposes that CSR promotes employee safety behavior through the mediation of psychological safety.

As the global economic situation deteriorates due to the prolonged COVID-19 pandemic, the business environment is plagued by uncertainty and risk. To address this, many organizations have sought to optimize efficiency, especially by downsizing and restructuring, to reduce costs. This causes anxiety among employees, who worry about whether they will be fired.

Although there has been extensive research on the corporate social responsibility (CSR)-performance link, full understanding is still elusive. A possible reason for this is the limited understanding of the underlying processes that affect the relationship. Grounded in institutional theory, which emphasizes the importance of micro-level intermediating processes (e.

A body of existing literature delves into how corporate social responsibility (CSR) affects employees' cognition, emotion, and behavior within an organization. These previous studies, however, pay relatively little attention to the influence of CSR on levels of creativity in employees. Considering that creativity is closely related to innovative capability, which is critical for a firm to survive, the relationship between CSR and employees' creativity and its elaborate underlying processes need further investigation.

Although previous works have examined how job insecurity affects the perceptions, attitudes, and behaviors of members in an organization, those studies have not paid enough attention to the relationship between job insecurity and performance or the mediating processes in that relationship. Considering that organizational performance is a fundamental target or purpose, investigating it is greatly needed. This research examines both mediating factors and a moderator in the link between job insecurity and organizational performance by building a moderated sequential mediation model.

Quantum confinement in inorganic semiconductor nanocrystals produces brightly luminescent nanoparticles endowed with unique photo-physical properties, such as tunable optical properties. These have found widespread applications in nanotechnology. The ability to render such nanostructures biocompatible, while maintaining their tunable radiation in the visible range of the electromagnetic spectrum, renders them appropriate for bio-applications.

Background: Previous MRI studies have investigated cortical or subcortical grey matter changes in patients with Parkinson's disease (PD), yielding inconsistent findings between the studies. We therefore sought to determine whether focal cortical or subcortical grey matter changes may be present from the early disease stage.

Methods: We recruited 49 untreated, early stage PD patients without dementia and 53 control subjects.
