- In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty-nonstandard errors (NSEs). We study NSEs by letting 164 teams test the same hypotheses on the same data. NSEs turn out to be sizable, but smaller for more reproducible or higher rated research. Adding peer-review stages reduces NSEs. We further find that this type of uncertainty is underestimated by participants.

Getting it done: Critical success factors for project managers in virtual work settings

- What conditions do project managers perceive as the most important to get the work done when working in fully dispersed settings? Rather than focusing on problems that managers experience when working in dispersed settings, our study highlights the conditions that are important for successful task accomplishment. We applied a Means-End-Chain (MEC) method to investigate the links between task accomplishment and relevant conditions that are attributes, benefits and values among a sample of experienced project managers (N = 30). Our results show that important conditions for successful project execution in a dispersed setting include rules of communication and its clarity; project management style and goal-setting; and managers' competences and trust in a team. In addition to these internal conditions, project managers also stress the importance of both corporate and technology support. These four conditions are all perceived as vital for task accomplishment in global dispersed projects.

Nature-based biopsychosocial resilience : An integrative theoretical framework for research on nature and health

Forskningsöversikt (refereegranskat)abstract
- Nature-based solutions including urban forests and wetlands can help communities cope better with climate change and other environmental stressors by enhancing social-ecological resilience. Natural ecosystems, settings, elements and affordances can also help individuals become more personally resilient to a variety of stressors, although the mechanisms underpinning individual-level nature-based resilience, and their relations to social-ecological resilience, are not well articulated. We propose ‘nature-based biopsychosocial resilience theory’ (NBRT) to address these gaps. Our framework begins by suggesting that individual-level resilience can refer to both: a) a person’s set of adaptive resources; and b) the processes by which these resources are deployed. Drawing on existing nature-health perspectives, we argue that nature contact can support individuals build and maintain biological, psychological, and social (i.e. biopsychosocial) resilience-related resources. Together with nature-based social-ecological resilience, these biopsychosocial resilience resources can: i) reduce the risk of various stressors (preventive resilience); ii) enhance adaptive reactions to stressful circumstances (response resilience), and/or iii) facilitate more rapid and/or complete recovery from stress (recovery resilience). Reference to these three resilience processes supports integration across more familiar pathways involving harm reduction, capacity building, and restoration. Evidence in support of the theory, potential interventions to promote nature-based biopsychosocial resilience, and issues that require further consideration are discussed.
