Bereavement, grief and consolation: emotional-affective geographies of loss during COVID-19

COVID-19 has resulted in a new global geographies of death ranging from cellular to global scales. These geographies are uneven, reflecting existing inequalities and failures of governance. In addition to death and bereavement, the pandemic has generated varied forms of loss and consolation, negative and positive affective atmospheres, whereby emotions are mobilised and politicised. Understanding these emotional-affective topographies, including ‘emotional-viral-loads’, is vital to wellbeing, resilience and unfolding policy interventions locally and globally

Conceptual modelling for simulation Part I: definition and requirements

Conceptual modelling is probably the most important aspect of a simulation study. It is also the most difficult and least understood. Over 40 years of simulation research and practice have provided only limited information on how to go about designing a simulation conceptual model. This paper, the first of two, discusses the meaning of conceptual modelling and the requirements of a conceptual model. Founded on existing literature, a definition of a conceptual model is provided. Four requirements of a conceptual model are described: validity, credibility, utility and feasibility. The need to develop the simplest model possible is also discussed. Owing to a paucity of advice on how to design a conceptual model, the need for a conceptual modelling framework is proposed. Built on the foundations laid in this paper, a conceptual modelling framework is described in the paper that follows
