A growing interest in the circular economy concept has pushed the discourse in various management-related disciplines beyond established boundaries, with calls to better address how such a model may be developed in a world of global value chains. Still, the conventional linear economy model continues to dominate business, society, and research. While the concept of better connecting physical output and input flows at multiple production or consumption levels is becoming more accepted, it remains unclear how to make this happen while ensuring that sustainability targets are met or exceeded.

This perspective calls for building greater understanding of the role that entrepreneurship plays in addressing the challenges to resource and waste management imposed by COVID-19. We contend that researchers and practitioners need to recognize that entrepreneurs are important change agents who can help in the transition to a more sustainable and circular economy. We present challenges as well as opportunities to address this gap with the goal to foster future research.

Article Synopsis
- Global population growth is increasing the demand for sustainable food systems, especially in urban areas, which highlights the environmental effects of current food production.
- Aquaponics offers a closed-loop method for growing seafood and vegetables, potentially minimizing this environmental impact.
- There are significant research gaps in studying diverse species, standardizing protocols, assessing environmental and economic impacts, and addressing health concerns related to produced food.
Background: Blood samples banked for up to 1 month are typically used to perform pretransfusion testing in humans and small animals, but this has not been validated using blood from horses.
Hypothesis: Compatibility of equine blood samples is repeatable using fresh samples, and reproducible using donor blood samples stored for up to 4 weeks.
Animals: Six healthy adult horses.
Background: As single incision surgery increases in popularity, the feasibility of offering this approach in bariatric surgery is further progression of this surgical technique. With the technical challenges that both operating on the morbidly obese patient and single incision surgery present, we describe our initial experience undertaking 111 single-incision gastric band insertions.
Methods: From June 2009 to October 2010, 111 obese patients underwent single-incision laparoscopic adjustable gastric banding through a single transverse incision using a multichannel single port and a pars flaccida technique.
