Phylogenetic inference based on evidence from DNA sequences has led to significant strides in the development of a stable and robustly supported framework for the vertebrate tree of life. To date, the bulk of those advances have relied on sequence data from a small number of genome regions that have proven unable to produce satisfactory answers to consistently recalcitrant phylogenetic questions. Here, we reexamine phylogenetic relationships among early-branching euteleostean fish lineages classically grouped in the Protacanthopterygii using DNA sequence data surrounding ultraconserved elements. We report and examine a dataset of thirty-four OTUs with 17,957 aligned characters from fifty-three nuclear loci. Phylogenetic analysis is conducted both in concatenated and joint gene trees and species tree estimation frameworks. Both analytical frameworks yield supporting evidence for existing hypotheses of relationship for the placement of Lepidogalaxias salamandroides, monophyly of the Stomiatii and the presence of an esociform + salmonid clade. Lepidogalxias salamandroides and the Esociformes + Salmoniformes are successive sister lineages to all other euteleosts in the two analysis types receiving high support values for this arrangement. However, interrelationships of Argentiniformes, Stomiatii and Neoteleostei remain uncertain as they varied by analysis type while receiving strong and contradictory indices of support. Topological differences between analysis types are apparent within the Ostarioclupeomorpha and the percomorph taxa in the data set. Our results identify concordant areas with strong support for relationships within and between early-branching euteleost lineages but they also reveal limitations in the ability of larger datasets to conclusively resolve other aspects of that phylogeny.

In spite of an increasing number of studies on ethical climate, little is known about the antecedents of ethical climate and the moderators of the relationship between ethical climate and work outcomes. The present study conducted firm-level analyses regarding the relationship between chief executive officer (CEO) ethical leadership and ethical climate, and the moderating effect of climate strength (i.e., agreement in climate perceptions) on the relationship between ethical climate and collective organizational citizenship behavior (OCB). Self-report data were collected from 223 CEOs and 6,021 employees in South Korea. The results supported all study hypotheses. As predicted, CEOs' self-rated ethical leadership was positively associated with employees' aggregated perceptions of the ethical climate of the firm. The relationship between ethical climate and firm-level collective OCB was moderated by climate strength. More specifically, the relationships between ethical climate and interpersonally directed collective OCB and between ethical climate and organizationally directed collective OCB were more pronounced when climate strength was high than when it was low. Theoretical and practical implications of these findings are addressed herein.

While the increasing sophistication of information technology has led to the spread of virtual organizations, there has been very little research on what factors contribute to individuals’ effectiveness in such organizations. This paper argues that organizations possess different degrees of virtuality based on four dimensions of temporal, spatial, cultural, and organizational dispersion. Using a person-environment fit framework, a theoretical model that identifies individual qualities required to fit into virtual organizations, virtual teams, and virtual jobs is developed, taking into account dimensions and degrees of virtuality. Mechanisms for enhancing fit in virtual organizations as well as theoretical and practical implications of the model are addressed.

As a result of the global economic recession over the past decade, employees have been exposed to constant threats of job insecurity. Despite having conducted extensive research on job insecurity, scholars have paid little attention to the motivational processes underlying employees’ reactions to job insecurity. The purpose of the present study is to examine the relationship between job insecurity, intrinsic motivation, and performance and behavioral outcomes. Drawing on self-determination theory (SDT), we propose a mediated relationship in which job insecurity decreases intrinsic motivation, which, in turn, undermines job performance, organizational citizenship behavior (OCB), and change-oriented OCB. To test our propositions, we collected survey-based data from 152 R&D professionals employed in a South Korean manufacturing company. As predicted, job insecurity was negatively related to intrinsic motivation, which, in turn, had a positive relationship with all three outcomes. Furthermore, job insecurity exerted significant indirect effects on job performance, OCB, and change-oriented OCB through intrinsic motivation. These findings affirm SDT, which posits that motivation, as a key intermediary process, affects employees’ reactions to job stressors.

Despite the vast amount of research on the antecedents of team performance, the role of subcultures in team contexts has only received scant attention. This study investigates the relationships between different types of team culture and team performance. Team-level analyses conducted on the leaders and members of 104 teams revealed a significant association between internal process team culture and team task performance, as well as a marginally significant relationship between human relations team culture and team task performance. Furthermore, team prevention focus mediated the relationships between internal process and human relations team cultures and team task performance. Team promotion focus mediated the relationship between open system team culture and team creative performance. These findings offer new insights regarding team culture, collective regulatory focus, and team performance.

Due to increasing organizational demand and competition, employees’ goal-pursuit regulatory processes become pivotal to their work behavior and outcomes. Drawing on interpersonal regulatory fit theory, we proposed that leader prevention focus would moderate the relation between follower prevention focus and maintenance organizational citizenship behavior (OCB), whereas the relation between follower promotion focus and change OCB would be moderated by leader promotion focus. We tested these fit hypotheses using cross-level polynomial regression analyses conducted on 117 leader and 641 followers in South Korean firms. The results showed that followers’ prevention focus was positively associated with their maintenance OCB. This main effect was more pronounced when the leader’s prevention focus was high than when it was low. While we detected a significant main effect of follower promotion focus on change OCB, no fit effect was found for promotion focus. The implications of these findings as well as directions for future research are addressed.

Despite the increasing significance of corporate ethics, few studies have explored the intermediate mechanisms that explain the relationship between corporate ethics and firm financial performance. Drawing on institutional theory and strategic human resource management literature, the authors hypothesize that the internal collective processes based on employees’ collective organizational commitment and organizational citizenship behavior (OCB) mediate the ethics–performance relationship at the organizational level. The authors’ hypotheses are tested using data collected from 3,821 employees from 130 Korean companies and the respective companies’ financial performance data. The results indicate that collective organizational commitment and interpersonal OCB are meaningful intervening processes that connect corporate ethics to firm financial performance. To complement prior studies that identify a firm’s reputation and external relations as mediators between corporate ethics and performance, the present study highlights the need to examine microprocesses occurring within the organization to account for the ethics–firm performance relationship. Moreover, the present demonstration of collective organizational commitment and OCB as meaningful predictors of a firm’s objective performance indicates the significance of these employee processes in explaining organizational-level outcomes.
