From schools of thought to an ecology of practices: Categorizing circular economy's futures.

In response to pressing societal challenges, scholars are increasingly focusing on research aimed at fostering sustainable futures. We contribute to that discussion by theorizing the circular economy (CE) as an "ecology of practices." The ecology of practices concept helps to make sense of a developing field that has been heavily practitioner-driven.

Using systems mapping to understand the constraints and enablers of solutions to plastic pollution.

Plastic pollution is now considered globally ubiquitous, irreversible, and a planetary boundary threat. Solutions are urgently needed but their development and application are hampered by the complexity and scale of the issue. System dynamics is a technique used to understand complex behaviours of systems through model building and is useful for conceptualising the relationships between various interacting, dynamic factors, and identifying potential intervention points within the system where specific policies or innovations might have the greatest impact or meet with the greatest resistance.

Predicting the natural history of metabolic syndrome with a Markov-system dynamic model: a novel approach.

Background: Markov system dynamic (MSD) model has rarely been used in medical studies. The aim of this study was to evaluate the performance of MSD model in prediction of metabolic syndrome (MetS) natural history.

Methods: Data gathered by Tehran Lipid & Glucose Study (TLGS) over a 16-year period from a cohort of 12,882 people was used to conduct the analyses.

The value of involving patients and public in health services research and evaluation: a qualitative study.

Background: Public and Patient Involvement, Engagement and Participation research encompasses working with patients/service users (people with a medical condition receiving health service treatment), public members, caregivers and communities (who use services or care for patients). The Partner Priority Programme (PPP) was developed by the National Health Service [NHS] and National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care [NIHR CLAHRC] NWC to share information and experience on evaluating new services being offered to patients that were seeking to reduce health inequalities, improve people's health and wellbeing and reduce emergency hospital admissions. This paper seeks to explore an approach developed for involving the public as equal partners within the evaluation and decision-making processes of health and social care services research.

The dynamics of metabolic syndrome development from its isolated components among Iranian adults: findings from 17 years of the Tehran lipid and glucose study (TLGS).

Background: Evaluating the process of changes in the Metabolic Syndrome (MetS) components over time is one of the ways to study of the MetS natural history. This study aimed to determine the trend of changes in the progression of MetS from its isolated components.

Methods: This longitudinal study was performed on four follow-up periods of the Tehran Lipid and Glucose Study (TLGS) between 1999 and 2015.
