Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

The Slippery Slope of Green Deeds: A Scoping Review of Moral Licensing in Studies on Proenvironmental Behaviors

open access: yesSustainable Development, EarlyView.
ABSTRACT The moral licensing theory (MLT) has been increasingly used to explain why proenvironmental behaviors (PEBs) sometimes lead to a decreased interest in sustainability (moral licensing), or how polluting actions might be followed by PEBs (moral cleansing). To shed light on how the MLT has been used in the studies on PEBs, this scoping review: (1)

Evaluation of Four Species of Wild Yams, as Potential Natural Reservoirs of Potyviruses Infecting Yams Cultivated in Togo

open access: yes, 2019
Yams cultivation in Togo is hampered by diseases caused by Potyviruses, mainly Yam mosaic virus (YMV) and Yam mild mosaic virus (YMMV). To understand the Potyviruses dissemination mechanism and to develop an efficient control method, the present study ...

Facilitating System Change With GOSR: Integrating AI and Human Collaboration

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Problem solving in complex domains requires approaches that encourage systems thinking, collaboration, and recognize multiple simultaneous solutions. Building from principles of General Systems Theory and existing problem structuring methods, we present a new method for supporting system partners working to address complex problems called GOSR.

A Comprehensive Stress and Breakage Analysis of Staple Fiber Yams: Part II: Breakage Analysis of Single Staple Fiber Yams

open access: yes, 1996
This paper contains the theory developed to describe the breaking mechanism of single staple fiber yams, based on the ideal conical helix model and the stress and breakage theory given in Part I.

Semester in Dialogue: A Systems Thinking Approach to Dialogue‐Based Higher Education at Simon Fraser University

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT This paper addresses a gap in the application of systems thinking to higher education programme design. We use the Complexity Theory of Outcome Creation (CTOC), a structured model for working in complexity, to analyse Simon Fraser University's Semester in Dialogue (SiD)—an innovative undergraduate programme applying the ideas of dialogic ...

Bia improved yams

open access: yes, 2014
Researchers at the University of Nigeria have shown that the dormancy period of white yams (Dioscorea rotundata) can be broken by applying the growth regulator BIA (butyric indolic acid) to the tubers before planting. Farmers can thus schedule..
