Gibson used "affordance" to describe how animals perceive and interact with their environment. Since the term was coined, many studies, both theoretical as well as empirical, have been done. We conducted a review of the 56 most cited works on physical affordances to answer: (1) What methods have been used to study affordances, and how have they changed with time? (2) How has the definition of affordances evolved over time? We went through papers decade-wise and compare their key contributions. Finally, we discuss how the definition and research on affordances has evolved in the last 40 years.

On June 11, 2018, the State of Qatar (Qatar) instituted legal proceedings against the United Arab Emirates (UAE) before the International Court of Justice (ICJ), alleging violations of the International Convention on the Elimination of All Forms of Racial Discrimination (CERD Convention). On the same day, Qatar also applied for provisional measures of protection.

2020 is a significant year for the International Criminal Court (ICC). Nearly two decades have passed since the entry into force of the Rome Statute and the establishment of the ICC, and there are valid questions being asked about the efficacy and value of the court. This is impelled in part by the track-record of the ICC. There are currently nine open preliminary examinations, thirteen examinations that have been granted the authorization to proceed to the investigation stage, and four investigations that have been closed without any further proceedings. Of the few cases that have eventually gone to trial, there have been four convictions and three acquittals. There have also been allegations of bias in the selection of situations and cases, and the politicization of justice. However, the complexities that need to be navigated by the court also must not be overlooked. These include the lack of cooperation by states, difficulties in accessing information and evidence, as well as mismatched expectations from the court and what it can achieve.
