Coronavirus disease 2019 (COVID-19) was first identified in China in late 2019 and is caused by newly identified severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Previous studies had reported the stability of SARS-CoV-2 in cell culture media and deposited onto surfaces under a limited set of environmental conditions. Here, we broadly investigated the effects of relative humidity, temperature, and droplet size on the stability of SARS-CoV-2 in a simulated clinically relevant matrix dried on nonporous surfaces. The results show that SARS-CoV-2 decayed more rapidly when either humidity or temperature was increased but that droplet volume (1 to 50 μl) and surface type (stainless steel, plastic, or nitrile glove) did not significantly impact decay rate. At room temperature (24°C), virus half-life ranged from 6.3 to 18.6 h depending on the relative humidity but was reduced to 1.0 to 8.9 h when the temperature was increased to 35°C. These findings suggest that a potential for fomite transmission may persist for hours to days in indoor environments and have implications for assessment of the risk posed by surface contamination in indoor environments. IMPORTANCE Mitigating the transmission of SARS-CoV-2 in clinical settings and public spaces is critically important to reduce the number of COVID-19 cases while effective vaccines and therapeutics are under development. SARS-CoV-2 transmission is thought to primarily occur through direct person-to-person transfer of infectious respiratory droplets or through aerosol-generating medical procedures. However, contact with contaminated surfaces may also play a significant role. In this context, understanding the factors contributing to SARS-CoV-2 persistence on surfaces will enable a more accurate estimation of the risk of contact transmission and inform mitigation strategies. To this end, we have developed a simple mathematical model that can be used to estimate virus decay on nonporous surfaces under a range of conditions and which may be utilized operationally to identify indoor environments in which the virus is most persistent.

In recent years, organisational theorists have been interested in the tensions faced by healthcare organisations. In this paper, these tensions are examined using the virtue approach to ethics of Alasdair MacIntyre. It is argued that although MacIntyre's framework shares many concerns with organisational studies, it supplements the analysis with a focus on moral content and evaluation. By providing moral evaluation of the stories told in organisations, an ethical analysis compels action on a basis that organisational studies does not. Nevertheless, it is the analysis of stories in organisation studies that provides the tools for taking action. The analysis presented here provides an example of how ethics and organisational studies can be brought together to provide a stronger analysis of organisational phenomena. Indeed, it provides support for Nielsen's position that organisational theory and ethics are co‐dependent and suggests that greater attention should be paid to ethical concepts in the study of organisational phenomena.

Examination of the application of virtue ethics to business has only recently started to grapple with the measurement of virtue frameworks in a practical context. This paper furthers this agenda by measuring the impact of virtue at the level of the organisation and examining the extent to which organisational virtue (OV) impacts on moral attentiveness (MA) and the perceived role of ethics and social responsibility in creating organisational effectiveness (PRESOR). It is argued that people who operate in more virtuous organisational contexts will be expected to be more attentive to ethical issues and in turn perceive a greater role for ethics and social responsibility in business. Analysis of results based on a sample of 137 HR professionals shows that where people report that their organisation provides meaningful work, they are more likely to display reflective MA and the belief that ethics and social responsibility are compatible with business objectives, suggesting that organisations who are interested in promoting an ethical culture should focus on their work structures and practices. More generally, OV is shown to have a more complex relationship with PRESOR than hypothesised pointing towards a more nuanced view of OV. The paper examines the implications of the results for organisations and research.
