Coping with Child Loss at Work – A Systematic Review, a Future Research Agenda, and Practice Recommendation
No full textDer Tod eines Kindes ist allgegenwärtig und hat erhebliche Folgen für Eltern und Unternehmen. Daher ist es von entscheidender Bedeutung zu verstehen, wie organisatorische Faktoren die verlust- und wiederherstellungsorientierte Bewältigung des Todes eines Kindes ihrer Mitarbeitenden beeinflussen. Auf der Grundlage eines systematic Reviews (k = 51 Studien) haben wir rollenbezogene und soziale Spannungen und Komplementaritäten identifiziert, durch die die Arbeit diesen Bewältigungsprozess beeinflusst. Diese Spannungen führen zu Anforderungen, die die Bewältigung durch die Beschäftigten erschweren. Rollenbezogene Spannungen stellen Anforderungen an das Boundary Management, die Entscheidungsfindung und die Emotionsregulierung. Soziale Spannungen stellen Anforderungen an das Impression Management und die Normkonformität. Umgekehrt helfen Komplementaritäten im Bewältigungsprozess. Rollenbezogene Komplementaritäten bieten Ablenkung und Ressourcen. Soziale Komplementaritäten sorgen für Zugehörigkeit und soziale Unterstützung. Auf der Grundlage unserer Untersuchung entwickeln wir Empfehlungen für Organisationen, Vorgesetzte und Mitarbeitende sowie für die künftige Forschung.Am 11. Dezember 2024 sprach Dr. Nina M. Junker, Associate Professor in Work & Organizational Psychology an der University of Oslo, Norwegen im ZPID-Kolloquium.Child loss is pervasive and has important consequences for individuals and organizations. Consequently, it is crucial to understand how organizational factors affect employees’ loss-oriented and restoration-oriented coping with child loss. Adopting an identity lens and based on a systematic review (k = 51 studies), we identified role-related and social tensions and complementarities through which work affects that coping process. These tensions add requirements that hamper employees’ coping. Role-related tensions add boundary-management, decision-making, and emotion-regulation requirements. Social tensions add impression-management and norm-conformity requirements. Conversely, complementarities help in the coping process. Role-related complementarities provide distraction and resources. Social complementarities provide belongingness and social support. We develop recommendations for organizations, supervisors, and co-workers and for future research based on our review.On December 11th, 2024 Nina M.

Helium burning and neutron sources in the stars
No full textHelium burning represents an important stage of stellar evolution as it contributes to the synthesis of key elements such as carbon, through the triple-α process, and oxygen, through the 12C(α,γ)16O reaction. It is the ratio of carbon to oxygen at the end of the helium burning stage that governs the following phases of stellar evolution leading to different scenarios depending on the initial stellar mass. In addition, helium burning in Asymptotic Giant Branch stars, provides the two main sources of neutrons, namely the 13C(α,n)16O and the 22Ne(α,n)25Mg, for the synthesis of about half of all elements heavier than iron through the s-process. Given the importance of these reactions, much experimental work has been devoted to the study of their reaction rates over the last few decades. However, large uncertainties still remain at the energies of astrophysical interest which greatly limit the accuracy of stellar models predictions. Here, we review the current status on the latest experimental efforts and show how measurements of these important reaction cross sections can be significantly improved at next-generation deep underground laboratories
Shedding light on electrodeposition dynamics tracked in situ via soft X-ray coherent diffraction imaging
No full textThe in situ physicochemical analysis of nanostructured functional materials is crucial for advances in their design and production. X-ray coherent diffraction imaging (CDI) methods have recently demonstrated impressive potential for characterizing such materials with a high spatial resolution and elemental sensitivity; however, moving from the current ex situ static regime to the in situ dynamic one remains a challenge. By combining soft X-ray ptychography and single-shot keyhole CDI, we performed the first in situ spatiotemporal study on an electrodeposition process in a sealed wet environment, employed for the fabrication of oxygen-reduction catalysts, which are key components for alkaline fuel cells and metal-air batteries. The results provide the first experimental demonstration of theoretically predicted Turing–Hopf electrochemical pattern formation resulting from morphochemical coupling, adding a new dimension for the in-depth in situ characterization of electrodeposition processes in space and time

An analysis of numerical trends in African elephant populations
No full textDissertation (MSc)--University of Pretoria, 2009.The elephant debate deals largely with population size, how elephant numbers change over time, how they may affect vegetation, and how their populations should be managed. Trends in elephant numbers frequently motivate management decisions, and past efforts to alleviate elephant impact aimed at controlling population size. However, methodological and statistical constraints may influence interpretation of trends and lead to incorrect management decisions. Furthermore, inferences about the response of elephant populations to specific management actions are seldom based on scientific evidence. In this thesis I assess the consequences of survey design and monitoring features on the interpretation and statistical reliability of population trends as well as the effect of population management on elephant densities and population growth rates. To do this, I collated information on elephant population estimates and past management actions across Africa. I used information from the northern Botswana elephant population to clarify temporal trends in elephant densities and numbers. Elephant numbers in northern Botswana increased from 1973 to 1993 while densities remained relatively stable. This difference in trends is due to an associated increase in survey area during the same time. In contrast, from 1996 to 2004 surveyed areas remained constant in size and neither elephant numbers, nor densities changed significantly during this time. This apparent stabilisation in numbers may have resulted from density-related elephant dispersal. This case study suggests that in open populations movements may complicate the interpretation of trends, and that differences in the rates of change in numbers and densities may have different management implications. The precision of population estimates, sample size, population size, and the magnitude of the annual rate of population change to be detected, affect power to identify trends. Two-thirds of the 156 time series that I assembled apparently were stable, and only 30 % of these had sufficient statistical power to detect population changes. These apparent stable trends without sufficient statistical power are inconclusive and should not be used to inform management decisions. Past elephant population management practices may have increased densities and growth rates in African elephant populations. Case studies of populations that were exposed to different management actions indicated that fencing of populations and water supplementation may have enhanced growth rates probably by influencing dispersal patterns. Thus, past management practices may have contributed to the ‘elephant problem’ by enhancing local elephant densities and population growth rates. In this thesis, I showed that trends based on elephant numbers may be misleading when the area over which elephants were counted, increased in size. Second, despite much effort and resources devoted to the monitoring of elephant populations for more than 50 years, population estimates and time series including such estimates had low quality, thereby reducing statistical power to detect trends in population change. Third, population growth rates were associated with management, where elephant population densities grew at faster rates when managed. Future conservation efforts should take into account the methodological and statistical constraints that may influence trend analyses of elephant populations and take cognizance of the fact that management decisions need to be evaluated against expected outcomes.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
