Publication Recommendations to Report Laboratory Data of Neonates - a Modified Delphi Approach

Background: Clinical and analytical information on laboratory data of neonates in scientific publications is sparse and incomplete. Furthermore, interpreting neonatal laboratory data can be complex due to their time-dependent and developmental physiology, and paucity of well-established age-appropriate reference ranges for neonates. This study aims to develop publication recommendations to report laboratory data of neonates to enhance the quality of these data in research and clinical care. Methods: A modified Delphi approach was used to develop recommendations in cooperation with the International Neonatal Consortium. A Core Group, including different stakeholders, was responsible for developing the recommendations, in collaboration with a Reflection Group, responsible for providing additional input. Results: The recommendations were classified into three categories: ‘Clinical Characteristics’, ‘Bio-analytical Information’ and ‘Data-analytical Information’. These were each divided into ‘Core Data’ (always to be reported) and ‘Supplemental Considerations’ (to be reported when considered relevant to the study). Conclusion: Our recommendations provide guidance on standardization of neonatal laboratory data in publications. This will enhance the comparison, replication, and application of study results in research initiatives and clinical practice. Furthermore, these recommendations also serve as foundational work to develop reference ranges for neonatal laboratory values by standardizing the quality of information needed for such efforts. Impact: Standardized reporting of neonatal laboratory data in scientific publications will enhance the comparison, replication, and application of study results in research initiatives and clinical practice, as well as improve reporting to regulatory agencies. To integrate multistakeholder perspectives, a modified Delphi approach was used to develop publication recommendations which strengthens the applicability of the recommendations. Implementation of standardization will likely improve the overall quality of neonatal clinical research and neonatal healthcare. In addition, these recommendations are foundational to develop reference ranges for neonatal laboratory values by standardizing the quality of information needed for such efforts.</p

Catalog of Galactic Beta Cephei Stars

We present an extensive and up-to-date catalog of Galactic Beta Cephei stars. This catalog is intended to give a comprehensive overview of observational characteristics of all known Beta Cephei stars. 93 stars could be confirmed to be Beta Cephei stars. For some stars we re-analyzed published data or conducted our own analyses. 61 stars were rejected from the final Beta Cephei list, and 77 stars are suspected to be Beta Cephei stars. A list of critically selected pulsation frequencies for confirmed Beta Cephei stars is also presented. We analyze the Beta Cephei stars as a group, such as the distributions of their spectral types, projected rotational velocities, radial velocities, pulsation periods, and Galactic coordinates. We confirm that the majority of these stars are multiperiodic pulsators. We show that, besides two exceptions, the Beta Cephei stars with high pulsation amplitudes are slow rotators. We construct a theoretical HR diagram that suggests that almost all 93 Beta Cephei stars are MS objects. We discuss the observational boundaries of Beta Cephei pulsation and their physical parameters. We corroborate that the excited pulsation modes are near to the radial fundamental mode in frequency and we show that the mass distribution of the stars peaks at 12 solar masses. We point out that the theoretical instability strip of the Beta Cephei stars is filled neither at the cool nor at the hot end and attempt to explain this observation

Temporal proximity matters:The impact of justice information timing on psychological contract breach resolution

Although scholars and practitioners argue that organizations should provide justice information in the aftermath of a psychological contract breach (PC breach) to prevent or reduce violation feelings, it remains unclear whether that information should be provided within a few hours, days, or weeks following a PC breach. We estimated a 2-level time-lagged regression model on experience sampling data from 76 (226 observations), 70 (213 observations), and 70 (344 observations) employees with different intervals to test the durability of informational justice as a moderator on the PC breach-violation feelings relationship. We found that justice information should be provided in close temporal proximity (i.e., within the same day; Study 1) of PC breach to reduce violation feelings. In contrast, neither justice information provided the day (Study 2) or week (Study 3) after a PC breach successfully moderated the PC breach-violation feelings relationship. The current paperunderscores the importance of being informationally just in close temporal proximity to a PC breach in line with resolution velocity as an indicator of the effectiveness of the recovery process. We discuss theoretical and practical implications of these findings

How psychological contract breach affects long-term mental and physical health: The longitudinal role of effort-reward imbalance

This study contributes to the research of employee health and well-being by examining the longitudinal effects of psychological contract (PC) breach on employees' health. We integrate Social Exchange and Conservation of Resources theories to position effort-reward imbalance (ERI) as the mediating mechanism. We also assessed the moderating role of perceived job control as a boundary condition through which employees could prevent PC breach and ERI from adversely affecting their health. Using three-wave longitudinal survey data from 389 employees, we estimated a path model using each variable's growth parameters (intercept and slope). We found support for our hypotheses regarding stable effects; we found positive associations between PC breach and physical and mental health complaints and a need for recovery through ERI perceptions. We further tested employees' perceived control over the work environment as a boundary condition and found support for its role in attenuating the positive relationship between PC breach and ERI perceptions, but not for its moderating role in the ERI-health outcomes relationship. Our findings indicate that exposure to PC breach has a detrimental impact on employee health/well-being via perceptions of ERI and allow us to unravel one of the cognitive mechanisms leading to potential employee ill-health. We conclude with theoretical and practical implications

What goes around comes around: How perpetrators of workplace bullying become targets themselves

In this study, we investigated whether and how perpetrators of bullying become targets themselves. Building on the notion of bullying as an escalation process and the Conservation of Resources Theory, we hypothesized that following enactment of bullying, people would experience increased relationship conflicts with colleagues, diminishing their sense of control and making them more likely to become exposed to bullying themselves. We tested this idea using longitudinal sequential mediated Structural Equation Modelling in a sample of 1420 Belgian workers. Our results confirmed that enactment of bullying lead to more exposure to bullying 18 months later. Relationship conflicts partially mediated this effect, meaning that bullying enactment can lead to increased tensions with others at work, increasing one's vulnerability to bullying exposure. Although perceived control also mediated the enactment-exposure relationship, relationship conflicts did not lead to perceived loss of control, suggesting a missing link in this relationship. Furthermore, the effect from perceived control to exposure to bullying was small and did not replicate in post-hoc analyses. Our findings suggest that people may experience a backlash from others in their work environment following engagement in bullying behavior at work and invite further exploration of the processes that may account for this relationship
