Abstract
Purpose
This study investigates the processes that the US universities and colleges used to learn during the COVID-19 pandemic and the factors that facilitated and impeded their learning processes.
Design/methodology/approach
To address this study’s research questions, this study used a crisis communication and learning lens to interview crisis response team members from 30 US higher education institutions in May 2020 (the first pandemic semester). In October 2020 (the second pandemic semester), this study conducted follow-up interviews with 25 of the original interviewees. Overall, this study conducted 55 interviews.
Findings
Learning during the COVID-19 pandemic is facilitated by a recognition of a serious deficiency in the current system and impeded by the need to act quickly. The findings demonstrate the process by which decisions, actions and strategies emerged during crises.
Originality/value
This investigation illustrates how crises can prompt organizational learning while demonstrating the critical role of internal and external resources in the learning process.

Abstract
Purpose
To examine the post 9/11 communication of the bond‐trading firm, Cantor Fitzgerald and its CEO Howard Lutnick, according to the discourse of renewal framework.
Design/methodology/approach
This case‐study of the discourse of renewal draws upon the messages and statements made by the company and its employees following the 9/11 attacks. The discourse of renewal framework emphasizes provisional responses, prospective statements, and the role of the leader as a symbol of stability in the face of a crisis.
Findings
This study provides support for viewing crisis as change‐inducing events with the potential to fundamentally alter the form, structure and direction of an organization. Renewal discourse helped the company survive an attack where over 600 employees were killed and the company offices completely destroyed. While a crisis inevitably create severe harm, it also has the potential to serve as a renewing force for the organization.
Research limitations/implications
Few examples of post‐crisis discourse of renewal have been examined in the literature and more research is needed. Work needs to identify the conditions necessary for this kind of discourse.
Practical implications
Organizations may have the opportunity to fundamentally reframe a crisis, focusing on the opportunities that arise from these events.
Originality/value
This paper explores both organizational crisis and organizational discourse from unique positions. Discourse is positioned as the means whereby crisis can become a positive force for change

Abstract
Purpose
The purpose of this paper is to analyse the signal dependency of the camera-based coaxial monitoring system QMMeltpool 3D (Concept Laser GmbH, Lichtenfels, Germany) for laser powder bed fusion (LPBF) under the variation of process parameters, position, direction and layer thickness to determine the capability of the system. Because such and similar monitoring systems are designed and presented for quality assurance in series production, it is important to present the dominant signal influences and limitations.
Design/methodology/approach
Hardware of the commercially available coaxial monitoring QMMeltpool 3D is used to investigate the thermal emission of the interaction zone during LPBF. The raw images of the camera are analysed by means of image processing to bypass the software of QMMeltpool 3D and to gain a high level of signal understanding. Laser power, scan speed, laser spot diameter and powder layer thickness were varied for single-melt tracks to determine the influence of a parameter variation on the measured sensory signals. The effects of the scan direction and position were also analysed in detail. The influence of surface roughness on the detected sensory signals was simulated by a machined substrate plate.
Findings
Parameter variations are confirmed to be detectable. Because of strong directional and positional dependencies of the melt-pool monitoring signal a calibration algorithm is necessary. A decreasing signal is detected for increasing layer thickness. Surface roughness is identified as a dominating factor with major influence on the melt-pool monitoring signal exceeding other process flaws.
Research limitations/implications
This work was performed with the hardware of a commercially available QMMeltpool 3D system of an LPBF machine M2 of the company Concept Laser GmbH. The results are relevant for all melt-pool monitoring research activities connected to LPBF, as well as for end users and serial production.
Originality/value
Surface roughness has not yet been revealed as being one of the most important origins for signal deviations in coaxial melt-pool monitoring. To the best of the authors’ knowledge, the direct comparison of influences because of parameters and environment has not been published to this extent. The detection, evaluation and remelting of surface roughness constitute a plausible workflow for closed-loop control in LPBF.

Abstract
Statistical methods of spatial analysis are often successful at either prediction or explanation, but not necessarily both. In a recent paper, Dearmon and Smith (2016) showed that by combining Gaussian Process Regression (GPR) with Bayesian Model Averaging (BMA), a modeling framework could be developed in which both needs are addressed. In particular, the smoothness properties of GPR together with the robustness of BMA allow local spatial analyses of individual variable effects that yield remarkably stable results. However, this GPR-BMA approach is not without its limitations. In particular, the standard (isotropic) covariance kernel of GPR treats all explanatory variables in a symmetric way that limits the analysis of their individual effects. Here we extend this approach by introducing a mixture of kernels (both isotropic and anisotropic) which allow different length scales for each variable. To do so in a computationally efficient manner, we also explore a number of Bayes-factor approximations that avoid the need for costly reversible-jump Monte Carlo methods.
To demonstrate the effectiveness of this Variable Length Scale (VLS) model in terms of both predictions and local marginal analyses, we employ selected simulations to compare VLS with Geographically Weighted Regression (GWR), which is currently the most popular method for such spatial modeling. In addition, we employ the classical Boston Housing data to compare VLS not only with GWR but also with other well-known spatial regression models that have been applied to this same data. Our main results are to show that VLS not only compares favorably with spatial regression at the aggregate level but is also far more accurate than GWR at the local level.

Abstract
Purpose
The purpose of this paper is to explore the ethical dimensions of crisis translation through the lenses of Paul Ricoeur’s philosophical scholarship. In particular, his work on both translation and ethics will be examined in order to draw practical applications for those involved in humanitarian action.
Design/methodology/approach
The authors identified relevant themes in the work of renowned philosopher Paul Ricoeur and used philosophical analysis to apply them to ethical issues in crisis translation.
Findings
Paul Ricoeur was one of the leading philosophers in the twentieth century, writing on a wide variety of topics. From these, his work on translation and on ethics provided suitable ways to examine ethical issues in crisis translation. In particular, his concept of “linguistic hospitality” provides an important lens through which translation ethics can be examined. In addition, Ricoeur’s approach to ethics emphasised relational and justice dimensions which are crucial to examine in humanitarian settings.
Practical implications
While the findings are conceptual, they have many practical implications for how translation is approached in humanitarian crises. The focus on justice in Ricoeur’s approach has implications for policy and practice and serves to ensure that translation is available for all affected communities and that all groups are included in discussions around humanitarian responses.
Social implications
Ricoeur’s work provides important insights into both translation and ethics that have significant social implications. His ideas highlight the personal and emotional aspects of translation and ethics, and point to their relational character. His openness to others provides an important basis for building trust and promoting dignity even in difficult humanitarian settings.
Originality/value
Ricoeur’s ethics points to the importance of persons and their relationships, reminding responders that translation is not just a mechanical exercise. This approach fosters an interest in and openness to others and their languages, which can promote respect towards those being helped in humanitarian crises.

Abstract
In this commentary, the authors introduce certain paradoxes of religious experience, ways the sacred is both attractive and repulsive, how there are urges to merge with the divine and to meaningfully change the world, how sacred power is both ineffable and accessible, how the divine can best be understood as a coincidence of opposites, how there is both good and evil in the world, and how religions sometimes proclaim peace yet instigate wars. The authors link these paradoxes with the contributions of the chapters in this volume on religion and philosophy. On the basis of both our and the chapters’ contributions the authors demonstrate several domains where religious paradox adds important insights to organizational approaches to paradox.

Abstract
Purpose
The main purpose of this paper is to provide empirical evidence for effective crisis communication in public emergencies including the relevance of planning and training and rehearsal; to explore the role of different stakeholders and how social media influence effective crisis communication.
Design/methodology/approach
A qualitative research design was employed. Two events were analysed, via the synthesis model for handling crisis communication in the public sector, as cases. First, via post-crisis semi-structured interviews, a gas explosion in the city of Antwerp was analysed. Second, via participant observation of a training and rehearsal exercise, more insight was gained on the role of training and social media for crisis communication.
Findings
The findings of this paper provide empirical evidence that (1) effective crisis communication is communication that is diversified across different crisis stages and diverse stakeholders; (2) that different internal social media tools and external social media tools are necessary to be monitored for effective crisis communication; (3) that training and rehearsal are of great importance for effective crisis communication.
Originality/value
This paper contributes to three current crisis communication research calls. First, the call for more research focusing on public sector crisis management, using public sector crisis communication models. Second, the call for the implementation of a more multiple-actor approach instead of an organisation-centred approach; and, third, the call for gaining insight into how specific communication channels are used before, during and after a crisis.

Abstract
Purpose
Disaster information is an important resource for flood preparedness, however, the transition of information provision to preparedness and consequently to damage reduction is complex. The nature of complexity has made it imperative to provide context-specific evidence on how disaster information provision influences intentions to prepare for flood hazard. This paper seeks to investigate how message clarity and source credibility mediate and moderate the relationship between information sufficiency and intentions to prepare. This paper aims to provide valuable insights into the relationship between the major components of disaster communication and their influence on intentions to prepare.
Design/methodology/approach
The study used a cross-sectional survey design to test the relationship between information sufficiency, message clarity and source credibility. A total of 1,064 questionnaire surveys were conducted on a face-to-face basis. The data collection was done in one month with ten research assistants. Participants of the study were randomly selected from adults over 18-years old who have lived in the study areas for at least three years. Responses from participants were analysed using a structural equation modelling (SEM) technique and SPSS AMOS version 24 software.
Findings
Findings suggest that the information sufficiency-intentions to prepare relationship is enhanced when adequate disaster information communicated is clear and from a credible source. This implies that policymakers and risk communicators need to critically assess the clarity of disaster information content and the credibility of the source in the dissemination of information during the communication process. It also provides a better understanding of the factors that influence people’s intentions to prepare for flood hazards.
Research limitations/implications
This current study did not account for the specific nature or content of information necessary to increase message clarity and source credibility for disaster preparedness. In addition, the study did not cover the channels of communication ideal to stimulate people’s intentions to flood preparedness. Although these do not undermine the significance of the present study, they present entry points for further studies. In view of the on-going urbanisation dynamics and the complex socio-spatial patterns emerging in the Greater Accra Area, it is recommended that further studies explore the channels of communication that will suit the diverse socio-spatial profile of residents (e.g. age, location, ethnicity, etc.).
Originality/value
While a plethora of studies emphasize the role of source credibility, information sufficiency and message clarity towards disaster preparedness, there is at present little evidence on the mediating and moderating role of the communication variables. In this study, we propose and test the mediating and moderating role of message clarity and source credibility on the relationship between information sufficiency and intentions to prepare. The findings of this paper provide other incentives that encourage message audiences to take up precautionary measures towards flood hazards. In addition, with a view that people fail to prepare because of lack of sufficient information, the study findings suggest that the provision of sufficient information may enhance preparedness.
