Monitoring how different people – as ‘social sensors’ – evaluate and respond to crisis such as pandemics, allows tailoring crisis communication to the social perceptions of the situation, at different moments. To gather such evidence, we proposed a index of social perceptions of systemic risk (SPSR), as an indicator of a situational threat compromising risks to physical health, psychological health, the economy, social relations, health system, and others. This indicator was the core of a social sensing approach applied to crisis situations, implemented during the COVID-19 pandemic through a content analysis of more than 130.000 public com-ments from Facebook™ users, in COVID-19 related publications. This content coding allowed creating a SPSR index monitored during a one-year descriptive longitudinal analysis. This index correlated with co-occurring events within the social system, namely epidemiological indicators across measurement cycles (e.g. new deaths; cumulative num-ber of infection cases; Intensive Care Unit hospitalizations) and tended to reflect the epidemiological situation severity (e.g. with the highest level registered during the worst pandemic wave). However, discrepancies also occurred, with high SPSR registered in a low severity situation, i.e. low number of hospitalizations and deaths (e.g. school year beginning), or low SPSR in a high severity situation (e.g. 2nd pandemic wave during Christmas), showing other factors beyond the epidemiological situation contributing to the social perceptions. After each ‘crisis period’ with SPSR peaking, there was a ‘restoration period’, consistently decreasing towards average levels of the previous measurement cycle. This can either indicate social resilience (recovery and resources potentiation) or risk attenuation after a high-severity period. This study serves as preliminary proof of concept of a crises social sensing approach, enabling monitoring of social system dynamics for various crisis types, such as health crisis or the climate crisis.
There Is Light and There Is Darkness: On the Temporal Dynamics of Cohesion, Coordination, and Performance in Business Teams
Publication . Marques-Quinteiro, Pedro; Rico Muñoz, Ramon; Passos, A. M.; Curral, Luis
This study examines teams as complex adaptive systems (tCAS) and uses latent
growth curve modeling to test team cohesion as an initial condition conducive to
team performance over time and the mediational effect of team coordination on this
relationship. After analyzing 158 teams enrolled in a business game simulation over five
consecutive weeks, we found that change in team coordination was best described
by a continuous linear change model, while change in team performance was best
described by a continuous nonlinear change model; and the mediation latent growth
curve model revealed a negative indirect effect of team cohesion on the level of change
in team performance over time, through the level of change in team coordination. This
study contributes to the science of teams by combining the notions of initial conditions
with co-evolving team dynamics, hence creating a more refined temporal approach to
understanding team functioning.
