Exploring the Process of Ethical Leadership: The Mediating Role of Employee Voice and Psychological Ownership
The study of ethical leadership has emerged as an important topic for understanding the effects of leadership in organizations. In a study with 845 working adults across multiple organizations, the relationships between ethical leadership with positive employee outcomes were examined. Results suggest that ethical leadership is related to both psychological well-being and job satisfaction in employees, but the processes are different. Employee voice mediated the relationship between ethical leadership and psychological well-being. Feelings of psychological ownership mediated the relationship between ethical leadership and job satisfaction. A discussion of theoretical and practical implications concludes the article
Individual identification and marking techniques for zebrafish
In laboratory fish research, the zebrafish Danio rerio (Cyprinidae) represents the equivalent of the mouse in mammalian research. This species has become a major model for studies in developmental and behavioural genetics, neurophysiology, biomedicine, ecotoxicology, and behavioural and evolutionary ecology. To meet the need for accurate and reproducible data in both fundamental and applied sciences, it is of primary importance to be able to tag and/or recognize individual zebrafish. However, classic methods used in fish ecology and aquaculture are generally difficult to apply to such small fish. Recently, various new tagging methods have been developed. This paper presents a first review of current identification and marking methods applied to zebrafish, from external observation methods (such as skin pattern recognition, fin clipping, scale regeneration, colour and transgenic methods) to the most advanced technological developments in electronic (low- and high- radio-frequencies PIT tags, microchip) and image analysis methods (video tracking). This review aims to help researchers and zebrafish facility managers select the identification method (ID) best adapted to their needs. The main characteristics of each ID method are examined (including detection range, durability, speed and repetitiveness, ID code combination, size dependence and ethical considerations), and their pros and cons are summarized in a decision table to help select the most appropriate option for a research or management program. Finally, contextual applications of these ID methods and future developments are discussed
