Circular business models (CBMs) focus on cycling, extending, intensifying, and/or dematerialising material and energy loops to reduce resource inputs and waste and emission leakage. We aim to explore consumer behaviour in circular economy through a systematic literature review to determine barriers and motivators to implementing CBMs, analysing twenty-eight articles. We identified internal motivations, such as economic and environmental concerns; and external factors facilitating engagement with circularity, such as better awareness, and products with design for circularity.

participants have an average annual carbon footprint of 844 kg of carbon dioxide-equivalent emissions. Thus, it is crucial to find solutions that reduce the sports industry's environmental impact. In this context, the circular economy emerges as a possible alternative. This paper analyses a sports production and retail company transitioning to the circular economy. First, we identified 154 internal circular projects concerning 89 product categories and classified them into different circular strategies and approaches. Then, we conducted interviews with 33 project representatives. Our results show that repair & maintenance is the most employed loop, but sharing economy and recycling also have an essential role. Each circularity loop presents specific challenges, but personal conviction is the common motivator. However, there is a need for greater allocation of resources such as time and budget. Additionally, strong governance is essential to structure these initiatives.

Much of the research on posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) has been conducted in high-income countries (HICs). However, PTSD and AUD commonly co-occur (PTSD + AUD) are both associated with high global burden of disease, and disproportionately impact those in low- and middle-income countries (LMICs). This narrative review attempts to synthesize the research on prevalence, impact, etiological models, and treatment of PTSD + AUD drawing from research conducted in HICs and discussing the research that has been conducted to date in LMICs. The review also discusses overall limitations in the field, including a lack of research on PTSD + AUD outside of HICs, issues with measurement of key constructs, and limitations in sampling strategies across comorbidity studies. Future directions are discussed, including a need for rigorous research studies conducted in LMICs that focus on both etiological mechanisms and on treatment approaches.

This study describes the development of a pilot sentinel school absence syndromic surveillance system. Using data from a sample of schools in England the capability of this system to monitor the impact of disease on school absences in school-aged children is shown, using the coronavirus disease 2019 (COVID-19) pandemic period as an example. Data were obtained from an online app service used by schools and parents to report their children absent, including reasons/symptoms relating to absence. For 2019 and 2020, data were aggregated into daily counts of ‘total’ and ‘cough’ absence reports. There was a large increase in the number of absence reports in March 2020 compared to March 2019, corresponding to the first wave of the COVID-19 pandemic in England. Absence numbers then fell rapidly and remained low from late March 2020 until August 2020, while lockdown was in place in England. Compared to 2019, there was a large increase in the number of absence reports in September 2020 when schools re-opened in England, although the peak number of absences was smaller than in March 2020. This information can help provide context around the absence levels in schools associated with COVID-19. Also, the system has the potential for further development to monitor the impact of other conditions on school absence, e.g. gastrointestinal infections.

The primary objectives of the ExoplANETS-A project are to: establish new knowledge on exoplanet atmospheres; establish new insight on influence of the host star on the planet atmosphere; disseminate knowledge, using online, web-based platforms. The project, funded under the EU’s Horizon-2020 programme, started in January 2018 and has a duration ∼3 years. We present an overview of the project, the activities concerning the host stars and some early results on the host stars.
