RESUMO

BACKGROUND: Two deep-sea eels collected from the Western Pacific Ocean are described in this study. Based on their morphological characteristics, the two deep-sea eel specimens were assumed to belong to the cusk-eel family Ophidiidae and the cutthroat eel family Synaphobranchidae. METHODS AND RESULTS: To accurately identify the species of the deep-sea eel specimens, we sequenced the mitochondrial genes (cytochrome c oxidase subunit I [COI] and 16S ribosomal RNA [16S rRNA]). Through molecular phylogenetic analysis based on mtDNA COI and 16S rRNA gene sequences, these species clustered with the genera Bassozetus and Synaphobranchus, suggesting that the deep-sea eel specimens collected are two species from the genera Bassozetus and Synaphobranchus in the Western Pacific Ocean, respectively. CONCLUSIONS: This is the first study to report new records of the genera Bassozetus and Synaphobranchus from the Western Pacific Ocean based on COI and 16S rRNA genes.

RESUMO

The dynamic interplay between Artificial Intelligence (AI) adoption in modern organizations and its implications for employee well-being presents a paramount area of academic exploration. Within the context of rapid technological advancements, AI's promise to revolutionize operational efficiency juxtaposes challenges relating to job stress and employee health. This study explores the nuanced effects of Artificial Intelligence (AI) adoption on employee physical health within organizational settings, investigating the potential mediating role of job stress and the moderating influence of coaching leadership. Drawing from the conservation of resource theory, the research hypothesized that AI adoption would negatively impact employee physical health both directly and indirectly through increased job stress. Critically, our conceptual model underscores the mediating role of job stress between AI adoption and physical health. Further, introducing a novel dimension to this discourse, we postulate the moderating influence of coaching leadership. To empirically test the hypotheses, we gathered survey data from 375 South Korean workers with a three-wave time-lagged research design. Our results demonstrated that all the hypotheses were supported. The results have significant implications for organizational strategies concerning AI implementation and leadership development.

RESUMO

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. The results of the study offer compelling evidence that CSR activities exert a positive influence on employees' knowledge-sharing behavior, an effect that is sequentially mediated by both perceived organizational support and organizational commitment. Furthermore, the research uncovers the positive moderating role played by the ethical climate in the relationship between CSR and perceived organizational support. By integrating multiple theoretical frameworks, this study not only advances the extant literature but also offers invaluable insights for organizations striving to bolster knowledge-sharing through the strategic implementation of CSR initiatives.

RESUMO

As the global economy deteriorates because of the great shocks such as COVID-19 pandemic and wars among nations, the business environment is suffered from uncertainty and risk. To deal with it, several firms have attempted to maximize its efficiency via downsizing and restructuring to diminish costs. Thus, the degree of anxiety is increased among employees who worry about the loss of their job. The current research hypothesizes that job insecurity increases employees' knowledge hiding behavior by diminishing the degree of their psychological safety. In other words, psychological safety functions as the underlying process (i.e., mediator) in the job insecurity-knowledge hiding behavior link. Furthermore, this paper tries to examine the boundary condition of how to decrease the detrimental influence of job insecurity, focusing on the moderating effect of servant leadership. Utilizing a 3-wave time-lagged data from 365 Korean employees, we empirically demonstrated that employees who perceive job insecurity are less likely to perceive psychological safety, eventually increasing their knowledge hiding behavior. We also found that servant leadership functions as a positive moderator which buffers the negative impact of job insecurity on psychological safety. Theoretical and practical contributions are described.

RESUMO

Swift social and economic environmental changes such as COVID-19 pandemic have led to increased job insecurity. The current study examines the intermediating mechanism (i.e., mediator) and its contingent factor (i.e., moderator) in the association between job insecurity and employee's turnover intention, especially from the perspective of positive psychology. By establishing a moderated mediation model, this research hypothesizes that the degree of employee meaningfulness in work may mediate the relationship between job insecurity and turnover intention. In addition, coaching leadership may play a buffering role to positively moderate the harmful impact of job insecurity on meaningfulness of work. With three-wave time-lagged data that was collected from 372 employees in South Korean organizations, the current study not only demonstrated that meaningfulness of work mediates the job insecurity-turnover intention relationship, but also that coaching leadership functions as a buffering factor in reducing the harmful influence of job insecurity on meaningfulness of work. The results of this research suggest that the level of meaningfulness of work (as a mediator) as well as coaching leadership (as a moderator) are the underlying processes and the contingent factor in the job insecurity-turnover intention link.

RESUMO

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. Furthermore, our paper undertakes a thorough analysis of the link between CSR and depression, probing its underlying processes and potential contingent factors. We posit that CSR can alleviate the incidence of employee depression by amplifying the sense of meaningfulness that work provides. Moreover, the element of prosocial motivation among employees may act as a positive moderating variable that intensifies the beneficial effect of CSR on the sense of meaningfulness derived from work. By relying on data obtained through a tripartite online survey involving 214 South Korean workers, this paper scrutinized the proposed hypotheses via the application of moderated mediation analysis with structural equation modeling. We contend that the insights yielded by this study bear significant theoretical and practical implications.

RESUMO

The purpose of this study was to investigate the influence of corporate social responsibility (CSR) on an employee's negative behavior, in addition to its intermediating mechanism (i.e., mediators and moderator) in the relationship. This paper proposes that CSR may diminish an employee's negative behavior, such as counterproductive work behavior. Relying on the context-attitude-behavior framework, this study investigated the mediators and moderator of the relationship between CSR and counterproductive work behavior. Specifically, this study hypothesized that not only does CSR diminish the level of counterproductive work behavior by sequentially boosting the level of employees' organizational trust and commitment, but their work overload also negatively moderates the association between CSR and organizational trust. Utilizing three-wave time-lagged online survey data from 342 employees in South Korean companies, this study tested the hypotheses by building a moderated mediation model with structural equation modeling analysis. The results indicate that CSR decreases the level of employees' counterproductive work behavior through enhancing their organizational trust and commitment. Moreover, work overload negatively moderates the association between CSR and organizational trust. The findings of this study make theoretical and practical contributions to the CSR literature.

RESUMO

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. In addition, authentic leadership may function as a positive moderator that amplifies the positive effect of CSR on psychological safety. Utilizing 3-wave time-lagged survey data from 213 South Korean workers, the current study empirically tests the hypotheses by establishing a moderated mediation model by utilizing structural equation modeling. The results demonstrate that CSR enhances employees' safety behavior by increasing their psychological safety and that authentic leadership positively moderates the relationship between CSR and psychological safety. This research's findings have meaningful theoretical and practical implications.

RESUMO

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. We hypothesize that such job insecurity increases knowledge-hiding behavior by employees, and we investigate the mechanism underlying such a negative effect. In addition, we attempt to capture the boundary conditions of how to reduce the adverse effects of job insecurity, focusing on the role of coaching leadership. Using three-wave time-lagged cohort-study data from 346 Korean workers, we empirically found that employees who perceive job insecurity are less likely to feel organizational identification, leading to increased knowledge-hiding behavior. This study also demonstrated that coaching leadership operates as a boundary condition which buffers the negative influence of job insecurity on organizational identification. Theoretical and practical implications are discussed.

RESUMO

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. To address these gaps, we examined both the mediator and the moderator in the association between job insecurity and negative employee behavior by establishing a moderated sequential mediation model. We hypothesized that the levels of employee job stress and organizational identification sequentially mediate the relationship between job insecurity and counterproductive work behavior as a representative negative behavior. We also hypothesized that CSR activities play a buffering role that moderates the influence of job insecurity on job stress. We used three-wave time-lagged data collected from 348 employees in South Korean organizations to demonstrate that job stress and organizational identification sequentially mediate the relationship between job insecurity and counterproductive work behavior, and that CSR activities function as a buffering factor that decreases the influence of job insecurity on job stress. The results of this research suggest that the levels of job stress and organizational identification (as sequential mediators) as well as CSR activities (as a moderator) are underlying mechanisms in the link between job insecurity and counterproductive work behavior.

RESUMO

Several characteristics of insurance fraud including its chronic nature justifies the need for identifying feasible proposals which can be expected to bring about significant impacts. Recent statistics show that insurance fraud is now consistently on the increase. However, insurance fraud is highly fragmented and each offence is not significant enough to elicit active interest among the public or interventions from the police. Three problems have been identified and diagnosed. These were a lack of awareness, an absence of a national leadership and also limited attention directed to insurance fraud by the investigating authorities. Based on these, three recommendations have been suggested. (1) Embarking on and developing a national initiative by central government, (2) Taking a dynamic concentration approach to send deterrent threats to potential fraudsters, and (3) Using big data technologies to detect clandestine activities by organised groups.

RESUMO

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.g., employees' perceptions and attitudes) to explain a macro-level association (i.e., CSR to organizational performance), we built a moderated mediation model where: (i) organization commitment mediated the influence of CSR on organizational performance, and (ii) an employee's prosocial motivation moderated the relationship between CSR and organizational commitment. Using three-wave time-lagged survey data obtained from 302 Korean workers, we found that organizational commitment is an important micro-level process in the CSR-performance link, and that the level of an employee's prosocial motivation can positively moderate that link. We discuss theoretical and practical implications, along with limitations and future research directions.

RESUMO

In the contemporary business environment where business ethics is critical for organizational performance, the importance of corporate social responsibility (CSR) is increasing. By investigating the mechanism of the effects of CSR on counterproductive work behavior (CWB), the present study suggests that CSR decreases negative employee behavior. Based on social identity theory and context-attitude-behavior framework, this research examines the underlying process and its contingent factor of the association between CSR and CWB. Specifically, this study hypothesizes that CSR decreases CWB by enhancing employees' organizational identification and that moral identity positively moderates the relationship between CSR and organizational identification. Using three-wave online survey data from 368 employees in Korean firms, this paper tested our hypotheses by conducting moderated mediation analysis with structural equation modeling. The results showed that CSR is negatively related to CWB through organizational identification and that moral identity positively moderates the relationship between CSR and organizational identification. The current study's findings have crucial theoretical and practical implications in CSR literature.

RESUMO

Although previous works have examined how work overload affects the perceptions, attitudes, and behaviors of members in an organization, those studies have paid insufficient attention to the mediating and contingent factors in the work overload-turnover intention link from the perspective of positive psychology. Considering the theoretical and practical value and importance of positive psychology, studies that use it to investigate underlying processes are needed. Also, existing studies on work overload have focused on the moderating role of individual-level variables to reduce the negative effects of work overload, mostly ignoring the importance of organizational-level moderators. To resolve those issues, we hypothesize that the meaningfulness of an employee's work mediates the relationship between work overload and turnover intention. Corporate social responsibility (CSR) practices could moderate the association between work overload and the meaningfulness of work. Using a three-wave data set gathered from 356 currently working employees in South Korea, we reveal not only that the meaningfulness of work mediates the work overload-turnover intention link, but also that CSR activities play a buffering role in the work overload-meaningfulness of work link. Our findings suggest that, from the perspective of positive psychology, the degree of meaningfulness of work (as a mediator) and CSR activities (as a moderator) function as intermediating mechanisms in the work overload-turnover intention link.

RESUMO

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. Based on a group creativity model, we argue that CSR may increase levels of creativity in employees through mediation of enhanced levels of psychological safety in employees. In addition, existing works on CSR have relatively underexplored the contextual role of leadership in translating CSR practices into employees' attitudes, perceptions, and behaviors. Using three-wave time-lagged survey data from 311 employees in South Korea, we found that CSR enhances employees' creativity via mediation of psychological safety. Additionally, ethical leadership positively moderates the relationship between CSR and psychological safety. Our findings suggest that psychological safety in employees functions as an important underlying mechanism to describe the CSR-employee creativity link. Furthermore, this paper emphasizes the importance of the moderating role of ethical leadership in the process of CSR activities.

RESUMO

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. To be specific, we hypothesize that the degree of an employee's job stress and organizational commitment sequentially mediate the relationship between job insecurity and performance. Furthermore, ethical leadership could moderate the association between job insecurity and job stress. Using a three-wave data set gathered from 301 currently working employees in South Korea, we reveal that not only do job stress and organizational commitment sequentially mediate the job insecurity-performance link, but also that ethical leadership plays a buffering role of in the job insecurity-job stress link. Our findings suggest that the degree of job stress and organizational commitment (as mediators), as well as ethical leadership (as a moderator), function as intermediating mechanisms in the job insecurity-performance link.

RESUMO

Although existing works have investigated the influence of employee's job insecurity on his or her perceptions or attitudes, those studies relatively have paid less attention to the influence of it on employee's behaviors, as well as to its intermediating mechanisms of the relationship between job insecurity and the behaviors. Considering that employee's behaviors substantially influence various organizational outcomes, I believe that studies which examine the impact of job insecurity on the behaviors as well as its underlying processes are required. Grounded on the context⁻attitude⁻behavior framework, I delved into the intermediating mechanism between job insecurity and organizational citizenship behavior with a sequential mediation model. In specific, I hypothesized that employee's organizational trust and organizational identification would sequentially mediate the job insecurity⁻organizational citizenship behavior (OCB) link. Utilizing 3-wave time-lagged data from 303 employees in South Korea, I found that organizational trust and organizational identification function as sequential mediators in the link. The finding suggests that organizational trust and organizational identification are underlying processes to elaborately explain the job insecurity⁻OCB link.

RESUMO

Although some previous studies have examined the impact of transformational leadership on safety behavior, those works have paid relatively less attention to the intermediating role of employees' job strain in the link as well as contingent variables that moderate the relationship. Considering that not only job strain substantially affects employees' perceptions, attitudes, and behaviors in an organization, but also there are some contextual factors that moderate the relationships, we investigated intermediating mechanisms (i.e., mediator and moderator) in the relationship between transformational leadership and safety behavior. Relying on the context-attitude-behavior framework, we conducted a structural equation modeling analysis with a moderated mediation model. Specifically, we hypothesized that the level of an employee's job strain would mediate the transformational leadership-safety behavior link. We also hypothesized that an employee's self-efficacy regarding safety would moderate the association between job strain and safety behavior. Using survey data from 997 South Korean employees, we found that all of our hypotheses were supported. The findings suggest that the level of an employee's job strain mediates and elaborately explains the transformational leadership-safety behavior link. Moreover, an employee's self-efficacy regarding safety is a buffering factor which decreases the harmful effects of job strain on safety behavior.
